金融体制、融资约束与投资——来自OECD的实证分析R.SemenovDepartment of Economics,University of Nijmegen,Nijmegen(荷兰内梅亨大学,经济学院)这篇论文考查了OECD的11个国家中现金流量对企业投资的影响.我们发现不同国家之间投资对企业内部可获取资金的敏感性具有显著差异,并且银企之间具有明显的紧密关系的国家的敏感性比银企之间具有公平关系的国家的低.同时,我们发现融资约束与整体金融发展指标不存在关系.我们的结论与资本市场信息和激励问题对企业投资具有重要作用这种观点一致,并且紧密的银企关系会减少这些问题从而增加企业获取外部融资的渠道。

一、引言各个国家的企业在显著不同的金融体制下运行。

金融发展水平的差别(例如,相对GDP的信用额度和相对GDP的相应股票市场的资本化程度),在所有者和管理者关系、企业和债权人的模式中,企业控制的市场活动水平可以很好地被记录.在完美资本市场,对于具有正的净现值投资机会的企业将一直获得资金。

然而,经济理论表明市场摩擦,诸如信息不对称和激励问题会使获得外部资本更加昂贵,并且具有盈利投资机会的企业不一定能够获取所需资本.这表明融资要素,例如内部产生资金数量、新债务和权益的可得性,共同决定了企业的投资决策.现今已经有大量考查外部资金可得性对投资决策的影响的实证资料(可参考,例如Fazzari(1998)、 Hoshi(1991)、 Chapman(1996)、Samuel(1998)).大多数研究结果表明金融变量例如现金流量有助于解释企业的投资水平。

这项研究结果解释表明企业投资受限于外部资金的可得性。

很多模型强调运行正常的金融中介和金融市场有助于改善信息不对称和交易成本,减缓不对称问题,从而促使储蓄资金投着长期和高回报的项目,并且提高资源的有效配置(参看Levine(1997)的评论文章)。

因而我们预期用于更加发达的金融体制的国家的企业将更容易获得外部融资.几位学者已经指出建立企业和金融中介机构可进一步缓解金融市场摩擦。

Inventory managementInventory ControlOn the so-called "inventory control", many people will interpret it as a "storage management", which is actually a big distortion.The traditional narrow view, mainly for warehouse inventory control of materials for inventory, data processing, storage, distribution, etc., through the implementation of anti-corrosion, temperature and humidity control means, to make the custody of the physical inventory to maintain optimum purposes. This is just a form of inventory control, or can be defined as the physical inventory control. How, then, from a broad perspective to understand inventory control? Inventory control should be related to the company's financial and operational objectives, in particular operating cash flow by optimizing the entire demand and supply chain management processes (DSCM), a reasonable set of ERP control strategy, and supported by appropriate information processing tools, tools to achieved in ensuring the timely delivery of the premise, as far as possible to reduce inventory levels, reducing inventory and obsolescence, the risk of devaluation. In this sense, the physical inventory control to achieve financial goals is just a means to control the entire inventory or just a necessary part; from the perspective of organizational functions, physical inventory control, warehouse management is mainly the responsibility of The broad inventory control is the demand and supply chain management, and the whole company's responsibility.Why until now many people's understanding of inventory control, limited physical inventory control? The following two reasons can not be ignored:First, our enterprises do not attach importance to inventory control. Especially those who benefit relatively good business, as long as there is money on the few people to consider the problem of inventory turnover. Inventory control is simply interpreted as warehouse management, unless the time to spend money, it may have been to see the inventory problem, and see the results are often very simple procurement to buy more, or did not do warehouse departments .Second, ERP misleading. Invoicing software is simple audacity to call it ERP, companies on their so-called ERP can reduce the number of inventory, inventory control, seems to rely on their small software can get. Even as SAP, BAAN ERP world, the field ofthese big boys, but also their simple modules inside the warehouse management functionality is defined as "inventory management" or "inventory control." This makes the already not quite understand what our inventory control, but not sure what is inventory control.In fact, from the perspective of broadly understood, inventory control, shouldinclude the following:First, the fundamental purpose of inventory control. We know that the so-called world-class manufacturing, two key assessment indicators (KPI) is, customer satisfaction and inventory turns, inventory turns and this is actually the fundamental objective of inventory control.Second, inventory control means. Increase inventory turns, relying solely on the so-called physical inventory control is not enough, it should be the demand and supply chain management process flow of this large output, and this big warehouse management processes in addition to including this link, the more important The section also includes: forecasting and order processing, production planning and control, materials planning and purchasing control, inventory planning and forecasting in itself, as well as finished products, raw materials, distribution and delivery of the strategy, and even customs management processes.And with the demand and supply chain management processes throughout the process, it is the information flow and capital flow management. In other words, inventory itself is across the entire demand and supply management processes in all aspects of inventory control in order to achieve the fundamental purpose, it must control all aspects of inventory, rather than just manage the physical inventory at hand.Third, inventory control, organizational structure and assessment.Since inventory control is the demand and supply chain management processes, output, inventory control to achieve the fundamental purpose of this process must be compatible with a rational organizational structure. Until now, we can see that many companies have only one purchasing department, purchasing department following pipe warehouse. This is far short of inventory control requirements. From the demand and supply chain management process analysis, we know that purchasing and warehouse management is the executive arm of the typical, and inventory control should focus on prevention, the executive branch is very difficult to "prevent inventory" for the simple reason that they assessment indicatorsin large part to ensure supply (production, customer). How the actual situation, a reasonable demand and supply chain management processes, and thus set the corresponding rational organizational structure and is a question many of our enterprisesto exploreThe role of inventory controlInventory management is an important part of business management. In the production and operation activities, inventory management must ensure that both the production plant for raw materials, spare parts demand, but also directly affect the purchasing, sales of share, sales activities. To make an inventory of corporate liquidity, accelerate cash flow, the security of supply under the premise of minimizing Yaku funds, directly affects the operational efficiency. Ensure the production and operation needs of the premise, so keep inventories at a reasonable level; dynamic inventory control, timely, appropriate proposed order to avoid over storage or out of stock; reduce inventory footprint, lower total cost of inventory; control stock funds used to accelerate cash flow.Problems arising from excessive inventory: increased warehouse space andinventory storage costs, thereby increasing product costs; take a lot of liquidity, resultingin sluggish capital, not only increased the burden of payment of interest, etc., would affect the time value of money and opportunity income; finished products and raw materials caused by physical loss and intangible losses; a large number of enterprise resource idle, affecting their rational allocation and optimization; cover the production, operation of the whole process of the various contradictions and problems, is not conducive to improve the management level.Inventory is too small the resulting problems: service levels caused a decline in the profit impact of marketing and corporate reputation; production system caused by inadequate supply of raw materials or other materials, affecting the normal production process; to shorten lead times, increase the number of orders, so order (production) costs; affect the balance of production and assembly of complete sets.NotesInventory management should particularly consider the following two questions:First, according to sales plans, according to the planned production of the goods circulated in the market, we should consider where, how much storage.Second, starting from the level of service and economic benefits to determine howto ensure inventories and supplementary questions.The two problems with the inventory in the logistics process functions.In general, the inventory function:(1)to prevent interrupted. Received orders to shorten the delivery of goods fromthe time in order to ensure quality service, at the same time to prevent out of stock.(2)to ensure proper inventory levels, saving inventory costs.(3)to reduce logistics costs. Supplement with the appropriate time interval compatible with the reasonable demand of the cargo in order to reduce logistics costs, eliminate or avoid sales fluctuations.(4)ensure the production planning, smooth to eliminate or avoid sales fluctuations.(5)display function.(6)reserve. Mass storage when the price falls, reduce losses, to respond to disasters and other contingencies.About the warehouse (inventory) on what the question, we must consider the number and location. If the distribution center, it should be possible according to customer needs, set at an appropriate place; if it is stored in central places to minimize the complementary principle to the distribution centers, there is no place certain requirements. When the stock base is established, will have to take into account are stored in various locations in what commodities.库存管理库存控制在谈到所谓“库存控制”的时候,很多人将其理解为“仓储管理”,这实际上是个很大的曲解。

外文文献原稿和译文原稿DATABASEA database may be defined as a collection interrelated data store together with as little redundancy as possible to serve one or more applications in an optimal fashion .the data are stored so that they are independent of programs which use the data .A common and controlled approach is used in adding new data and in modifying and retrieving existing data within the data base .One system is said to contain a collection of database if they are entirely separate in structure .A database may be designed for batch processing , real-time processing ,or in-line processing .A data base system involves application program, DBMS, and database.THE INTRODUCTION TO DATABASE MANAGEMENT SYSTEMSThe term database is often to describe a collection of related files that is organized into an integrated structure that provides different people varied access to the same data. In many cases this resource is located in different files in different departments throughout the organization, often known only to the individuals who work with their specific portion of the total information. In these cases, the potential value of the information goes unrealized because a person in other departments who may need it does not know it or it cannot be accessed efficiently. In an attempt to organize their information resources and provide for timely and efficient access, many companies have implemented databases.A database is a collection of related data. By data, we mean known facts that can be recorded and that have implicit meaning. For example, the names, telephone numbers, and addresses of all the people you know. You may have recorded this data in an indexed address book, or you may have stored it on a diskette using a personalcomputer and software such as DBASE Ⅲor Lotus 1-2-3. This is a collection of related data with an implicit meaning and hence is a database.The above definition of database is quite general. For example, we may consider the collection of words that made up this page of text to be usually more restricted. A database has the following implicit properties:● A database is a logically coherent collection of data with some inherent meaning. A random assortment of data cannot be referred to as a database.● A database is designed, built, and populated with data for a specific purpose. It has an intended group of user and some preconceived applications in which these users are interested.● A database represents some aspect of the real world, sometimes called the miniworld. Changes to the miniworld are reflected in the database.In other words, a database has some source from which data are derived, some degree of interaction with events in the real world, and an audience that is actively interested in the contents of the database.A database management system (DBMS) is composed of three major parts: (1) a storage subsystem that stores and retrieves data in files; (2)a modeling and manipulation subsystem that provides the means with which to organize the data and to add, delete, maintain, and update the data; and (3) an interface between the DBMS and its users. Several major trends are emerging that enhance the value and usefulness of database management systems.●Managers who require more up-to-date information to make effective decisions.●Customers who demand increasingly sophisticated information services and more current information about the status of their orders, invoices, and accounts.●Users who find that they can develop custom applications with database systems in a fraction of the time it takes to use traditional programming languages.●Organizations that discover information has a strategic value; they utilize their database systems to gain an edge over their competitors.A DBMS can organize, process, and present selected data elements from the database. This capability enables decision makers to search, probe, and query database contents in order to extract answers to nonrecurring and unplanned questions that aren’t available in regular reports. These questions might initially be vague and/or p oorly defined, but people can “browse” through the database until they have the needed information. In short, the DBMS will “mange” the stored data items and assemble the needed items from the common database in response to the queries of those who aren’t programmers. In a file-oriented system, user needing special information may communicate their needs to a programmer, who, when time permits, will write one or more programs to extract the data and prepare the information. The availability of a DBMS, however, offers users a much faster alternative communications path.DATABASE QUERYIf the DBMS provides a way to interactively enter and update the database ,as well as interrogate it ,this capability allows for managing personal database. However, it does not automatically leave an audit trail of actions and does not provide the kinds of controls necessary in a multi-user organization .There controls are only available when a set of application programs is customized for each data entry and updating function.Software for personal computers that perform some of the DBMS functions has been very popular .Individuals for personal information storage and processing intended personal computers for us .Small enterprises, professionals like doctors, architects, engineers, lawyers and so on have also used these machines extensively. By the nature of intended usage ,database system on there machines are except from several of the requirements of full-fledged database systems. Since data sharing is not intended, concurrent operations even less so ,the software can be less complex .Security and integrity maintenance are de-emphasized or absent .as data volumes will be small, performance efficiency is also less important .In fact, the only aspect of a database system that is important is data independence. Data independence ,as stated earlier ,means that application programs and user queries need not recognize physical organization of data on secondary storage. The importance of this aspect , particularly for the personal computer user ,is that this greatly simplifies database usage . The user can store ,access and manipulate data at ahigh level (close to the application)and be totally shielded from the low level (close to the machine )details of data organization.DBMS STRUCTURING TECHNIQUESSpatial data management has been an active area of research in the database field for two decades ,with much of the research being focused on developing data structures for storing and indexing spatial data .however, no commercial database system provides facilities for directly de fining and storing spatial data ,and formulating queries based on research conditions on spatial data.There are two components to data management: history data management and version management .Both have been the subjects of research for over a decade. The troublesome aspect of temporal data management is that the boundary between applications and database systems has not been clearly drawn. Specifically, it is not clear how much of the typical semantics and facilities of temporal data management can and should be directly incorporated in a database system, and how much should be left to applications and users. In this section, we will provide a list of short-term research issues that should be examined to shed light on this fundamental question.The focus of research into history data management has been on defining the semantics of time and time interval, and issues related to understanding the semantics of queries and updates against history data stored in an attribute of a record. Typically, in the context of relational databases ,a temporal attribute is defined to hold a sequence of history data for the attribute. A history data consists of a data item and a time interval for which the data item is valid. A query may then be issued to retrieve history data for a specified time interval for the temporal attribute. The mechanism for supporting temporal attributes is to that for supporting set-valued attributes in a database system, such as UniSQL.In the absence of a support for temporal attributes, application developers who need to model and history data have simply simulated temporal attributes by creating attribute for the time interval ,along with the “temporal” attribute. This of course may result in duplication of records in a table, and more complicated search predicates in queries. The one necessary topic of research in history data management is to quantitatively establish the performance (and even productivity) differences betweenusing a database system that directly supports attributes and using a conventional database system that does not support either the set-valued attributes or temporal attributes.Data security, integrity, and independenceData security prevents unauthorized users from viewing or updating the database. Using passwords, users are allowed access to the entire database of the database, called subschemas. For example, an employee database can contain all the data about an individual employee, but one group of users may be authorized to view only payroll data, while others are allowed access to only work history and medical data.Data integrity refers to the accuracy, correctness, or validity of the data in the database. In a database system, data integrity means safeguarding the data against invalid alteration or destruction. In large on-line database system, data integrity becomes a more severe problem and two additional complications arise. The first has to do with many users accessing the database concurrently. For example, if thousands of travel agents book the same seat on the same flight, the first agent’s booking will be lost. In such cases the technique of locking the record or field provides the means for preventing one user from accessing a record while another user is updating the same record.The second complication relates to hardware, software or human error during the course of processing and involves database transaction which is a group of database modifications treated as a single unit. For example, an agent booking an airline reservation involves several database updates (i.e., adding the passenger’s name and address and updating the seats-available field), which comprise a single transaction. The database transaction is not considered to be completed until all updates have been completed; otherwise, none of the updates will be allowed to take place.An important point about database systems is that the database should exist independently of any of the specific applications. Traditional data processing applications are data dependent.When a DMBS is used, the detailed knowledge of the physical organization of the data does not have to be built into every application program. The application program asks the DBMS for data by field name, for example, a coded representationof “give me customer name and balance due” would be sent to the DBMS. Without a DBMS the programmer must reserve space for the full structure of the record in the program. Any change in data structure requires changes in all the applications programs.Data Base Management System (DBMS)The system software package that handles the difficult tasks associated with creating ,accessing and maintaining data base records is called a data base management system (DBMS). A DBMS will usually be handing multiple data calls concurrently.It must organize its system buffers so that different data operations can be in process together .It provides a data definition language to specify the conceptual schema and most likely ,some of the details regarding the implementation of the conceptual schema by the physical schema.The data definition language is a high-level language, enabling one to describe the conceptual schema in terms of a “data model “.At the present time ,there are four underling structures for database management systems. They are :List structures.Relational structures.Hierarchical (tree) structures.Network structures.Management Information System(MIS)An MIS can be defined as a network of computer-based data processing procedures developed in an organization and integrated as necessary with manual and other procedures for the purpose of providing timely and effective information to support decision making and other necessary management functions.One of the most difficult tasks of the MIS designer is to develop the information flow needed to support decision making .Generally speaking ,much of the information needed by managers who occupy different levels and who have different levels and have different responsibilities is obtained from a collection of exiting information system (or subsystems)Structure Query Language (SQL)SQL is a data base processing language endorsed by the American NationalStandards Institute. It is rapidly becoming the standard query language for accessing data on relational databases .With its simple ,powerful syntax ,SQL represents a great progress in database access for all levels of management and computing professionals.SQL falls into two forms : interactive SQL and embedded SQL. Embedded SQL usage is near to traditional programming in third generation languages .It is the interactive use of SQL that makes it most applicable for the rapid answering of ad hoc queries .With an interactive SQL query you just type in a few lines of SQL and you get the database response immediately on the screen.译文数据库数据库可以被定义为一个相互联系的数据库存储的集合。

外文文献翻译译稿1卡尔曼滤波的一个典型实例是从一组有限的,包含噪声的,通过对物体位置的观察序列(可能有偏差)预测出物体的位置的坐标及速度。

在很多工程应用(如雷达、计算机视觉)中都可以找到它的身影。

同时,卡尔曼滤波也是控制理论以及控制系统工程中的一个重要课题。

例如,对于雷达来说,人们感兴趣的是其能够跟踪目标。

但目标的位置、速度、加速度的测量值往往在任何时候都有噪声。

卡尔曼滤波利用目标的动态信息,设法去掉噪声的影响,得到一个关于目标位置的好的估计。

这个估计可以是对当前目标位置的估计(滤波),也可以是对于将来位置的估计(预测),也可以是对过去位置的估计(插值或平滑)。

命名[编辑]这种滤波方法以它的发明者鲁道夫.E.卡尔曼(Rudolph E. Kalman)命名,但是根据文献可知实际上Peter Swerling在更早之前就提出了一种类似的算法。

施密特(Stanley Schmidt)首次实现了卡尔曼滤波器。

卡尔曼在NASA埃姆斯研究中心访问时,发现他的方法对于解决阿波罗计划的轨道预测很有用,后来阿波罗飞船的导航电脑便使用了这种滤波器。

关于这种滤波器的论文由Swerling(1958)、Kalman (1960)与Kalman and Bucy(1961)发表。

当一国的经济增长的可持续性岌岌可危的时候,金融业的改革一直被认为是提高资金使用效率和消费型经济增长重新走向平衡的必要(Lardy,1998年,Prasad,2007年)。

事实上,不久前,中国的国有银行被视为“技术上破产”,它们的生存需要依靠充裕的国家流动资金。

但是,在银行改革开展以来,最近,强劲的盈利能力已恢复到国有商业银行的水平。

但自从中国的国有银行在不久之前已经走上了改革的道路,它可能过早宣布银行业的改革尚未取得完全的胜利。

此外,其坚实的财务表现虽然强劲,但不可持续增长。

随着经济增长在2008年全球经济衰退得带动下已经开始软化,银行预计将在一个比以前更加困难的经济形势下探索。

本文的目的不是要评价银行业改革对银行业绩的影响,这在一个完整的信贷周期后更好解决。

相反,我们的目标是通过审查改革的进展和银行改革战略,并分析其近期改革后的强劲的财务表现,但是这不能完全从迄今所进行的改革努力分离。

国际贸易对碳排放的影响外文文献翻译中英文

外文文献翻译(含:英文原文及中文译文)英文原文The effects of international trade on Chinese carbon emissionsB Wei ,X Fang ,Y WangAbstractInternational trade is an important impact factor to the carbon emissions of a country. As the rapid development of Chinese foreign trade since its entry into the WTO in 2002, the effects of international trade on carbon emissions of China are more and more significant. Using the recent available input-output tables of China and energy consumption data, this study estimated the effects of Chinese foreign trade on carbon emissions and the changes of the effects by analyzing the emissions embodied in trade between 2002 and 2007. The results showed a more and more significant exporting behavior of embodied carbon emissions in Chinese international trade. From 2002 to 2007, the proportion of net exported emissions and domestic exported emissions in domestic emissions increased from 18.32% to 29.79% and from 23.97% to 34.76%, respectively. In addition, about 22.10% and 32.29% of the total imported emissions were generated in processing trade in 2002 and 2007, respectively, which were imported and later exported emissions. Although, most of the sectors showed a growth trend in imported and exportedemissions, sectors of electrical machinery and communication electronic equipment, chemical industry, and textile were still the biggest emission exporters, the net exported emissions of which were also the largest. For China and other developing countries, technology improvement may be the most favorable and acceptable ways to reduce carbon emissions at present stage. In the future negotiations on emissions reduction, it would be more fair and reasonable to include the carbon emissions embodied in international trade when accounting the total emissions of an economy. Keywords: input-output analysis, carbon emissions, international trade, ChinaIntroductionGlobal warming has been considered an indisputable fact. The main reason is that the warming of the global climate system is due to the continuous increase in the concentration of greenhouse gases in the atmosphere, the result of human activities (IPCC, 2007). In order to avoid the possible negative impact on human society's global warming, a series of measures have been taken to reduce global greenhouse gas emissions to slow down global warming. However, around the CO2 emission reduction and the future allocation of carbon emission rights, the game plays a different interest group.With the development of globalization, the impact on the international trade of the environment is becoming more and moresignificant, including the potential impact of carbon emissions from geographical relocation. Many researchers estimate that it is reflected in international trade in certain countries as well as in the world economy (Wykoff and Rupp, carbon emissions in 1994; Schaefer and Lealdesa, 1996, Machado et al., 2001 Year; Munksgaard, Peder and Sen, 2001; Ahmed and Wykov, 2003; Sanchez-Chóliz and Duarte, 2004; Peters and Hess, 2006, 2008; Mäenpää et al, 2007; Keman et al., 2007). The general conclusion is that in a more open economy, the impact of large foreign trade on the carbon emissions of a country. In addition, all these studies have pointed out that import and export trade cannot ignore a relatively open economy; otherwise, energy and carbon emissions figures may be seriously distorted by this economy (Machado et al., 2001). In terms of total volume, the value of China’s trade surplus increased from US$30.43 billion in 2002 to US$261.83 billion in 2007 (National Bureau of Statistics, 2008). The rapid growth of China’s foreign trade will have a significant effect on China’s carbon emissions.As one of the countries with the highest carbon emissions, China is facing increasing pressure to reduce emissions. However, China is also a big country in international trade. The rapid development of China’s economy has led to steady growth in foreign trade. From 1997 to 2002, China’s total import and export value increased by an average annual growth rate of 14.35%. Since joining the World Trade Organization, theaverage annual growth rate of China’s trade has jumped to 28.64%. From 2002 to 2007, the value of exports compared with 2002, it increased by 2.7 times in 2007 to reach US$1.2177.8 billion. Imports also soared to US$955.95 billion in 2007, which was 2.2 times higher than the 2002 imports. In terms of total volume, the value of China’s trade surplus increased from US$30.43 billion in 2002 to US$261.83 billion in 2007 (National Bureau of Statistics, 2008). The rapid growth of China’s foreign trade will have a significant effect on China’s carbon emissions.However, quantitative assessment of the impact of China's international trade in energy use and carbon emissions has only recently begun. Estimates from the IEA (2007) show that China's domestic production and export of energy-related carbon dioxide emissions account for 34% of total emissions, and if it is used in 2004, the weighted average carbon intensity of commodity countries imported from China is estimated. China's net exports of EM-rich CO2 may be more than 17% of total emissions in 2004 (Levin, 2008). Using a single-area input-output model, Pan et al. (2008) estimated that their production of energy and emissions in 2002 accounted for 16% and 19% of China’s net exports of primary energy consumption, respectively, in 2002. In the input-output analysis, China reported that the discharge volume of pre-grid discharges to the United States accounted for about 5%. Weber et al. (2008), ESTI mating production exported from China's carbon dioxide emissions from1987 to 2005. In 2005, about one-third of China's emissions were due to production exports, and this proportion has risen from 12% in 1987 to 21% in 2002. In developed countries, consumption is driving this trend. Wei et al.'s estimation (2009a) also found that the presence of emissions in China's economy in 2002 reflected significant export behavior; in addition, subsequent exports (processing trade played by EMIS--) were total imports of 20 %the above. In addition, using a multi-area input-output model, Peters and Hewei (2008) also found that export emissions represented 24.4% of China's domestic emissions, and the proportion of imports in 2001 was only 6.6%. A similar study by Atkinson et al. (2009) also shows that China is a net exporter of carbon emissions in international trade. In recent years, using ecological input-output based on physical access programs, MOD-Y eling, Chen and Chen (2010) estimated that in 2007 China's export of carbon dioxide emissions and total energy were respectively 32.31% and 33.65% of total emissions.Both the United States and European countries are major importers of China’s export carbon emissions. Using the economic input-output life cycle assessment software, Ruihe Harris (2006) found that about 7% of China’s carbon dioxide emissions from exports to the United States during the period of 1997-2003 were produced by 14% of the total; the US’s CO2 emissions will At 3%-6%, if increased imports from Chinahave been produced in the United States. AP-walking a similar approach, Lee Hewitt found that bilateral trade between the United Kingdom and China (2008) produced about 4% of CO2 emissions. In 2004, China's CO2 emissions were for the UK market to produce goods and the UK trade decreased. About 11%. Weber et al. (2008) also found that most of China’s recent export emissions went to developed countries, approximately 27% of the United States, 19% of the EU-27, and 14% of the remaining Annex B countries, mainly Japan and Australia. And New Zealand. Recently, Xu et al. (2009) studied the impact of energy consumption and exhaust emissions on the environment. From 2002 to 2007, the use of environmental input-output analysis and adjustment of bilateral trade data reflected trade in the East (from China to the United States). Zhang (2009) has also obtained similar results. Energy and CO2 account for about 12% and 17% of China's energy consumption, and China's CO2 emissions are 8% and 12%, respectively.Although China's international trade is a meaningful research on carbon emissions, further related research is necessary because of the rapid development of China's foreign trade, especially the development of processing trade. According to statistics (National Bureau of Statistics, 2008), the export share of processing trade has been more than 50% of total exports since 1996. In 2002 and 2007, the share of processing trade reached 55.26% and 50.71%, which will be processing trade. Thenecessary distinction between the impact of general trade and China's carbon emissions.Since China's input-output table is only 5 years, we have chosen from 2002 (entry to the WTO) to 2007 (the latest issue), and China's international trade input-output table has impact on carbon emissions with the view of the last requirement of this paper. Influence changes. In addition, we distinguish between domestic processing trade and import investment in the assessment of production processes (import emissions and re-exports), which will help us to further understand the impact of international trade on emissions status. In this study, we tried to answer three questions: 1) What is the net emissions generated by foreign trade in China as a big country's foreign trade? 2) China from 2002 to 2007, International How does trade affect carbon emissions? 3) From 2002 to 2007, which departments were the major emitters of China's import and export trade and their roles?Uncertainty in the calculation of carbon emissionsThe calculation of emissions from China's trade reflects a certain degree of uncertainty. One is that the input-output analysis itself has many inherent uncertainties (more discussion in Lenzen, 2001). Based on an input-output table for China's single region, it allows us to obtain a relatively accurate assessment of the emissions that are reflected in China's exports, but this error may be more pronounced when estimatingthe emissions of goods and services exported to China. (Lenzen , 2001; Lenzen et al., 2004). Another important factor of uncertainty is that the calculations come from different regions, which may underestimate the method of importing the carbon intensity factor that is reflected in the import of larger proportion of finished product producing countries and tertiary industries, and the smaller proportion of secondary industries. In addition, the method of pro-grade introduction of the column will inevitably result in some errors in order to obtain a matrix from the inlet of the original import and export table.At present, for reasons of data availability, we cannot fully quantify the accuracy of our calculations, but preliminary estimates suggest that the use of more accurate data results from research will not significantly change the conclusions of this analysis. These restrictions will be improved through the use of multi-zone import and export tables and out-of-zone more detailed industry carbon intensity and sector-to-sector production processes in the future for detailed analysis.Understand the impact of international trade on carbon emissions in ChinaFrom 2002 to 2007, the impact of foreign trade on China’s carbon emissions has greatly expanded. It may be largely related to two factors. The first is the coal-based energy consumption structure. The secondary industry-based production structure will maintain high domestic energyintensity. In 2002, the coal consumption exchange was only 66.3% of the total energy consumption. The 44.8% of China's gross domestic product (GDP) is due to the secondary industry in 2002 (National Bureau of Statistics, 2008). In 2007, related stock prices rose as high as 69.5% and 48.6%, respectively, which will lead to the fact that the unit exports are higher than the carbon emissions reflected in unit imports. The second factor, which may be a more important factor, is the rapid growth of export trade. From 2002 to 2007, China’s exports increased by 246.80%, while imports increased by 199.97% (National Bureau of Statistics, 2008). Export growth is significantly higher than imports, which may lead to a sharp increase in net exports. Decomposition analysis using input and output structures, Liu et al. (2010) also found that the total export expansion of export and energy-intensive products tends to expand, reflecting the export of energy from 1992 to 2005, but the improvement and change of energy efficiency in the primary energy consumption structure can offset part of the impact on export energy. The above driving force is implemented.Although, based on the coal-based energy consumption structure, the carbon dioxide emissions produced by the secondary industry-based production structure, the more important role, it may be difficult for China to adjust because of its endowment characteristics, and in a very short time Its structural characteristics and its current economicdevelop ment stage. In addition, the expansion of China’s foreign trade, including the expansion of the trade surplus, is mainly the result of the market economy’s maximizing its comparative advantage. The development-replacement of China's economy not only provided many of the world's goods and services, but also reduced the nation's production-based relative costs in developed countries. China’s foreign trade has always played an important role in the development of the world economy, due to its huge market, stable government system and abundant cheap labor. Therefore, it can be argued that at the current stage, for China's better methods to reduce the impact of international trade on national or global CO2 emissions should be to improve its production technology, reduce the intensity of energy consumption as a whole, not only to control China The amount of foreign trade. In addition, the imported goods from China should take part in China's carbon emission responsibilities, because the CON-consumer demand of foreign consumers has generated a large amount of China's carbon emissions, especially for consumers in developed countries.ConclusionDespite some uncertainties in this study, most areas produced from the details of the data, we can conclude that international trade has a significant impact on China's carbon emissions, and changed the impact of time on going. Compared with 2002 emissions, domestic exportemissions in 2007 increased from 267.07 MTC to 718.31 MTC, with a speed increase of over 160%; net exports also increased correspondingly, from 204.08 MTC up to 615.65 MTC, over 200% growth rate Now. From 23.97% in 2002, the share of domestic emissions from domestic emissions jumped to 34.76% in 2007. The share of pre-net transplants that exceeded domestic emissions also rose from 18.32% in 2002 to 29.79% in 2007. The results show that more and more significant net export behaviors of implied carbon emissions exist in China's economy and processing trade have more and more significant effects on carbon emissions.Regardless of the emissions of imported emissions or exports, most industries showed a growth trend in 2007. Compared with 2002, emissions although the sectoral emissions have changed for the entire economy from 2002 to 2002, The impact, of which the largest percentage of imported major department or China's export emissions remain unchanged. The largest import emissions (all or actual imports) come from the industries of electrical machinery and communications electronics, chemicals, smelting and rolling plus metals. Electrical machinery and communications electronics equipment, chemicals, textiles and other sectors are the largest emitters of exports, net exports of which are also the largest. Technological progress may be the most favorable and acceptable way for China and other developing countries toreduce their carbon emissions. Considering that the world’s largest carbon emissions and the recent increase in emissions are in developing countries, the historical responsibility for the current responsibilities, developed countries should also take more efforts to help developing countries reduce their carbon emissions. Economic growth through technical assistance And financial support. In the car's list of future emissions reductions, which include the total economic output, the carbon emissions reflected in international trade will be fair and reasonable.中文译文国际贸易对中国碳排放的影响: 一份具有经验性的分析作者:B Wei ,X Fang ,Y Wang摘要国际贸易是一个国家碳排放量重要的影响因素,自2002年加入世贸组织,中国对外贸易的快速发展对碳排放的影响越来越显著。

However, the ability of SMEs to grow depends highly on their potential to invest in restructuring, innovation and qualification. All of these investments need capital and therefore access to finance.Against this background the consistently repeated complaint of SMEs about their problems regarding access to finance is a highly relevant constraint that endangers the economic recovery of Europe.Changes in the finance sector influence the behavior of credit institutes towards Crafts, Trades and SMEs. Recent and ongoing developments in the banking sector add to the concerns of SMEs and will further endanger their access to finance. The main changes in the banking sector which influence SME finance are:•Globalization and internationalization have increased the competition and the profit orientation in the sector;•worsening of the economic situations in some institutes (burst of the ITC bubble, insolvencies) strengthen the focus on profitability further;•Mergers and restructuring created larger structures and many local branches, which had direct and personalized contacts with small enterprises, were closed;•up-coming implementation of new capital adequacy rules (Basel II) will also change SME business of the credit sector and will increase its administrative costs;•Stricter interpretation of State-Aide Rules by the European Commission eliminates the support of banks by public guarantees; many of the effected banks are very active in SME finance.All these changes result in a higher sensitivity for risks and profits in the financesector.The changes in the finance sector affect the accessibility of SMEs to finance.Higher risk awareness in the credit sector, a stronger focus on profitability and the ongoing restructuring in the finance sector change the framework for SME finance and influence the accessibility of SMEs to finance. The most important changes are: •In order to make the higher risk awareness operational, the credit sector introduces new rating systems and instruments for credit scoring;•Risk assessment of SMEs by banks will force the enterprises to present more and better quality information on their businesses;•Banks will try to pass through their additional costs for implementing and running the new capital regulations (Basel II) to their business clients;•due to the increase of competition on interest rates, the bank sector demands more and higher fees for its services (administration of accounts, payments systems, etc.), which are not only additional costs for SMEs but also limit their liquidity;•Small enterprises will lose their personal relationship with decision-makers in local branches –the credit application process will become more formal and anonymous and will probably lose longer;•the credit sector will lose more and more i ts “public function” to provide access to finance for a wide range of economic actors, which it has in a number of countries, in order to support and facilitate economic growth; the profitability of lending becomes the main focus of private credit institutions.All of these developments will make access to finance for SMEs even more difficult and / or will increase the cost of external finance. Business start-ups and SMEs, which want to enter new markets, may especially suffer from shortages regarding finance. A European Code of Conduct between Banks and SMEs would have allowed at least more transparency in the relations between Banks and SMEs and UEAPME regrets that the bank sector was not able to agree on such a commitment.Towards an encompassing policy approach to improve the access of Crafts, Trades and SMEs to financeAll analyses show that credits and loans will stay the main source of finance for the SME sector in Europe. Access to finance was always a main concern for SMEs, but the recent developments in the finance sector worsen the situation even more.Shortage of finance is already a relevant factor, which hinders economic recovery in Europe. Many SMEs are not able to finance their needs for investment.Therefore, UEAPME expects the new European Commission and the new European Parliament to strengthen their efforts to improve the framework conditions for SME finance. Europe’s Crafts, Trades and SMEs ask for an encompassing policy approach, which includes not only the conditions for SMEs’ access to l ending, but will also strengthen their capacity for internal finance and their access to external risk capital.From UEAPME’s point of view such an encompassing approach should be based on three guiding principles:•Risk-sharing between private investors, financial institutes, SMEs and public sector;•Increase of transparency of SMEs towards their external investors and lenders;•improving the regulatory environment for SME finance.Based on these principles and against the background of the changing environment for SME finance, UEAPME proposes policy measures in the following areas:1. New Capital Requirement Directive: SME friendly implementation of Basel IIDue to intensive lobbying activities, UEAPME, together with other Business Associations in Europe, has achieved some improvements in favour of SMEs regarding the new Basel Agreement on regulatory capital (Basel II). The final agreement from the Basel Committee contains a much more realistic approach toward the real risk situation of SME lending for the finance market and will allow the necessary room for adaptations, which respect the different regional traditions and institutional structures.However, the new regulatory system will influence the relations between Banks and SMEs and it will depend very much on the way it will be implemented into European law, whether Basel II becomes burdensome for SMEs and if it will reduce access to finance for them.The new Capital Accord form the Basel Committee gives the financial market authorities and herewith the European Institutions, a lot of flexibility. In about 70 areas they have room to adapt the Accord to their specific needs when implementing itinto EU law. Some of them will have important effects on the costs and the accessibility of finance for SMEs.UEAPME expects therefore from the new European Commission and the new European Parliament:•The implementation of the new Capital Requirement Directive will be costly for the Finance Sector (up to 30 Billion Euro till 2006) and its clients will have to pay for it. Therefore, the implementation – especially for smaller banks, which are often very active in SME finance –has to be carried out with as little administrative burdensome as possible (reporting obligations, statistics, etc.).•The European Regulators must recognize traditional instruments for collaterals (guarantees, etc.) as far as possible.•The European Commission and later the Member States should take over the recommendations from the European Parliament with regard to granularity, access to retail portfolio, maturity, partial use, adaptation of thresholds, etc., which will ease the burden on SME finance.2. SMEs need transparent rating proceduresDue to higher risk awareness of the finance sector and the needs of Basel II, many SMEs will be confronted for the first time with internal rating procedures or credit scoring systems by their banks. The bank will require more and better quality information from their clients and will assess them in a new way. Both up-coming developments are already causing increasing uncertainty amongst SMEs.In order to reduce this uncertainty and to allow SMEs to understand the principles of the new risk assessment, UEAPME demands transparent rating procedures –rating procedures may not become a “Black Box” for SMEs: •The bank should communicate the relevant criteria affecting the rating of SMEs.•The bank should inform SMEs about its assessment in order to allow SMEs to improve.The negotiations on a European Code of Conduct between Banks and SMEs , which would have included a self-commitment for transparent rating procedures by Banks, failed. Therefore, UEAPME expects from the new European Commission and the new European Parliament support for:•binding rules in the framework of the new Capital Adequacy Directive,which ensure the transparency of rating procedures and credit scoring systems for SMEs;•Elaboration of national Codes of Conduct in order to improve the relations between Banks and SMEs and to support the adaptation of SMEs to the new financial environment.3. SMEs need an extension of credit guarantee systems with a special focus on Micro-LendingBusiness start-ups, the transfer of businesses and innovative fast growth SMEs also depended in the past very often on public support to get access to finance. Increasing risk awareness by banks and the stricter interpretation of State Aid Rules will further increase the need for public support.Already now, there are credit guarantee schemes in many countries on the limit of their capacity and too many investment projects cannot be realized by SMEs.Experiences show that Public money, spent for supporting credit guarantees systems, is a very efficient instrument and has a much higher multiplying effect than other instruments. One Euro form the European Investment Funds can stimulate 30 Euro investments in SMEs (for venture capital funds the relation is only 1:2).Therefore, UEAPME expects the new European Commission and the new European Parliament to support:•The extension of funds for national credit guarantees schemes in the framework of the new Multi-Annual Programmed for Enterprises;•The development of new instruments for securitizations of SME portfolios;•The recognition of existing and well functioning credit guarantees schemes as collateral;•More flexibility within the European Instruments, because of national differences in the situation of SME finance;•The development of credit guarantees schemes in the new Member States;•The development of an SBIC-like scheme in the Member States to close the equity gap (0.2 – 2.5 Mio Euro, according to the expert meeting on PACE on April 27 in Luxemburg).•the development of a financial support scheme to encourage the internalizations of SMEs (currently there is no scheme available at EU level: termination of JOP, fading out of JEV).4. SMEs need company and income taxation systems, whichstrengthen their capacity for self-financingMany EU Member States have company and income taxation systems with negative incentives to build-up capital within the company by re-investing their profits. This is especially true for companies, which have to pay income taxes. Already in the past tax-regimes was one of the reasons for the higher dependence of Europe’s SMEs on bank lending. In future, the result of rating w ill also depend on the amount of capital in the company; the high dependence on lending will influence the access to lending. This is a vicious cycle, which has to be broken.Even though company and income taxation falls under the competence of Member States, UEAPME asks the new European Commission and the new European Parliament to publicly support tax-reforms, which will strengthen the capacity of Crafts, Trades and SME for self-financing. Thereby, a special focus on non-corporate companies is needed.5. Risk Capital – equity financingExternal equity financing does not have a real tradition in the SME sector. On the one hand, small enterprises and family business in general have traditionally not been very open towards external equity financing and are not used to informing transparently about their business.On the other hand, many investors of venture capital and similar forms of equity finance are very reluctant regarding investing their funds in smaller companies, which is more costly than investing bigger amounts in larger companies. Furthermore it is much more difficult to set out of such investments in smaller companies.Even though equity financing will never become the main source of financing for SMEs, it is an important instrument for highly innovative start-ups and fast growing companies and it has therefore to be further developed. UEAPME sees three pillars for such an approach where policy support is needed:Availability of venture capital•The Member States should review their taxation systems in order to create incentives to invest private money in all forms of venture capital.•Guarantee instruments for equity financing should be further developed.Improve the conditions for investing venture capital into SMEs•The development of secondary markets for venture capital investments in SMEs should be supported.•Accounting Standards for SMEs should be revised in order to easetransparent exchange of information between investor and owner-manager.Owner-managers must become more aware about the need for transparency towards investors•SME owners will have to realise that in future access to external finance (venture capital or lending) will depend much more on a transparent and open exchange of information about the situation and the perspectives of their companies.•In order to fulfil the new needs for transparency, SMEs will have to use new information instruments (business plans, financial reporting, etc.) and new management instruments (risk-management, financial management, etc.).外文资料翻译涂敏之会计学 8051208076题目:未来的中小企业融资背景:中小企业融资已经改变未来的经济复苏将取决于能否工艺品,贸易和中小企业利用其潜在的增长和创造就业。

儿童教育外文翻译文献(文档含中英文对照即英文原文和中文翻译)原文:The Role of Parents and Community in the Educationof the Japanese ChildHeidi KnipprathAbstractIn Japan, there has been an increased concern about family and community participation in the child’s educat ion. Traditionally, the role of parents and community in Japan has been one of support and less one of active involvement in school learning. Since the government commenced education reforms in the last quarter of the 20th century, a more active role for parents and the community in education has been encouraged. These reforms have been inspired by the need to tackle various problems that had arisen, such as the perceived harmful elements of society’spreoccupation with academic achievement and the problematic behavior of young people. In this paper, the following issues are examined: (1) education policy and reform measures with regard to parent and community involvement in the child’s education; (2) the state of parent and community involvement at the eve of the 20th century.Key Words: active involvement, community, education reform, Japan, parents, partnership, schooling, supportIntroduction: The Discourse on the Achievement GapWhen western observers are tempted to explain why Japanese students attain high achievement scores in international comparative assessment studies, they are likely to address the role of parents and in particular of the mother in the education of the child. Education mom is a phrase often brought forth in the discourse on Japanese education to depict the Japanese mother as being a pushy, and demanding home-bound tutor, intensely involved in the child’s education due to severe academic competition. Although this image of the Japanese mother is a stereotype spread by the popular mass media in Japan and abroad, and the extent by which Japanese mothers are absorbed in their children is exaggerated (Benjamin, 1997, p. 16; Cummings, 1989, p. 297; Stevenson & Stigler, 1992, p. 82), Stevenson and Stigler (1992) argue that Japanese parents do play an indispensable role in the academic performance of their children. During their longitudinal and cross-national research project, they and their collaborators observed that Japanese first and fifth graders persistently achieved higher on math tests than American children. Besides reciting teacher’s teaching style, cultural beliefs, and organization of schooling, Stevenson and Stigler (1992) mention parent’s role in supporting the learning conditions of the child to explain differences in achievement between elementary school students of the United States and students of Japan. In Japan, children receive more help at home with schoolwork (Chen & Stevenson, 1989; Stevenson & Stigler, 1992), and tend to perform less household chores than children in the USA (Stevenson et al., 1990; Stevenson & Stigler, 1992). More Japanese parents than American parents provide space and a personal desk and purchase workbooks for their children to supplement their regular text-books at school (Stevenson et al., 1990; Stevenson & Stigler, 1992). Additionally, Stevenson and Stigler (1992) observed that American mothers are much more readily satisfied with their child’s performance than Asian parents are, have less realistic assessments of their child’s academic perform ance, intelligence, and other personality characteristics, and subsequently have lower standards. Based on their observation of Japanese, Chinese and American parents, children and teachers, Stevenson and Stigler (1992) conclude that American families can increase the academic achievement of their children by strengthening the link between school and home, creating a physical and psychological environment that is conducive to study, and by making realistic assessments and raising standards. Also Benjamin (1997), who performed ‘day-to-day ethnography’ to find out how differences in practice between American and Japanese schools affect differences in outcomes, discusses the relationship between home and school and how the Japanese mother is involved in the academic performance standards reached by Japanese children. She argues that Japanese parents are willing to pay noticeable amounts of money for tutoring in commercial establishments to improve the child’s performance on entrance examinations, to assist in ho mework assignments, to facilitate and support their children’s participation in school requirements and activities, and to check notebooks of teachers on the child’s progress and other school-related messages from the teacher. These booklets are read and written daily by teachers and parents. Teachers regularly provide advice and reminders to parents, and write about homework assignments of the child, special activities and the child’s behavior (Benjamin, 1997, p. 119, p. 1993–1995). Newsletters, parents’ v isits to school, school reports, home visits by the teacher and observation days sustain communication in later years at school. According toBenjamin (1997), schools also inform parents about how to coach their children on proper behavior at home. Shimahara (1986), Hess and Azuma (1991), Lynn (1988) and White (1987) also try to explain national differences in educational achievement. They argue that Japanese mothers succeed in internalizing into their children academic expectations and adaptive dispositions that facilitate an effective teaching strategy, and in socializing the child into a successful person devoted to hard work.Support, Support and SupportEpstein (1995) constructed a framework of six types of involvement of parents and the community in the school: (1) parenting: schools help all families establish home environments to support children as students; (2) communicating: effective forms of school-to-home and home-to-school communications about school programs and children’s progress; (3) volu nteering: schools recruit and organize parents help and support; (4) learning at home: schools provide information and ideas to families about how to help students at home with homework and other curriculum-related activities, decisions and planning; (5) decision making: schools include parents in school decisions, develop parent leaders and representatives; and (6) collaborating with the community: schools integrate resources and services from the community to strengthen school programs, family practices, and student learning and development. All types of involvement mentioned in studies of Japanese education and in the discourse on the roots of the achievement gap belong to one of Epstein’s first four types of involvement: the creation of a conducive learn ing environment (type 4), the expression of high expectations (type 4), assistance in homework (type 4), teachers’ notebooks (type 2), mother’s willingness to facilitate school activities (type3) teachers’ advice about the child’s behavior (type 1), observ ation days by which parents observe their child in the classroom (type 2), and home visits by the teachers (type 1). Thus, when one carefully reads Stevenson and Stigler’s, Benjamin’s and other’s writings about Japanese education and Japanese students’ high achievement level, one notices that parents’ role in the child’s school learning is in particular one of support, expected and solicited by the school. The fifth type (decision making) as well as the sixth type (community involvement) is hardly ever mentioned in the discourse on the achievement gap.In 1997, the OECD’s Center for Educational Research and Innovation conducted a cross-national study to report the actual state of parents as partners in schooling in nine countries, including Japan. In its report, OECD concludes that the involvement of Japanese parents in their schools is strictly limited, and that the basis on which it takes place tends to be controlled by the teacher (OECD, 1997, p. 167). According to OECD (1997), many countries are currently adopting policies to involve families closely in the education of their children because (1) governments are decentralizing their administrations; (2) parents want to be increasingly involved; and (3) because parental involvement is said to be associated with higher achievement in school (p. 9). However, parents in Japan, where students already score highly on international achievement tests, are hardly involved in governance at the national and local level, and communication between school and family tends to be one-way (Benjamin, 1997; Fujita, 1989; OECD, 1997). Also parent–teacher associations (PTA, fubo to kyoshi no kai ) are primarily presumed to be supportive of school learning and not to participate in school governance (cf. OECD, 2001, p. 121). On the directionsof the occupying forces after the second world war, PTA were established in Japanese schools and were considered with the elective education boards to provide parents and the community an opportunity to participate actively in school learning (Hiroki, 1996, p. 88; Nakata, 1996, p. 139). The establishment of PTA and elective education boards are only two examples of numerous reform measures the occupying forces took to decentralize the formal education system and to expand educational opportunities. But after they left the country, the Japanese government was quick to undo liberal education reform measures and reduced the community and parental role in education. The stipulation that PTA should not interfere with personnel and other administrative tasks of schools, and the replacement of elective education boards by appointed ones, let local education boards believe that parents should not get involved with school education at all (Hiroki, 1996, p. 88). Teachers were regarded to be the experts and the parents to be the laymen in education (Hiroki, 1996, p. 89).In sum, studies of Japanese education point into one direction: parental involvement means being supportive, and community involvement is hardly an issue at all. But what is the actual state of parent and community involvement in Japanese schools? Are these descriptions supported by quantitative data?Statistics on Parental and Community InvolvementTo date, statistics of parental and community involvement are rare. How-ever, the school questionnaire of the TIMSS-R study did include some interesting questions that give us a clue about the degree of involvement relatively compared to the degree of involvement in other industrialized countries. The TIMSS-R study measured science and math achievement of eighth graders in 38 countries. Additionally, a survey was held among principals, teachers and students. Principals answered questions relating to school management, school characteristics, and involvement. For convenience, the results of Japan are only compared with the results of those countries with a GNP of 20650 US dollars or higher according to World Bank’s indicators in 1999.Unfortunately, only a very few items on community involvement were measured. According to the data, Japanese principals spend on average almost eight hours per month on representing the school in the community (Table I). Australian and Belgian principals spend slightly more hours and Dutch and Singaporean principals spend slightly less on representing the school and sustaining communication with the community. But when it comes to participation from the community, Japanese schools report a nearly absence of involvement (Table II). Religious groups and the business community have hardly any influence on the curriculum of the school. In contrast, half of the principals report that parents do have an impact in Japan. On one hand, this seems a surprising result when one is reminded of the centralized control of the Ministry of Education. Moreover, this control and the resulting uniform curriculum are often cited as a potential explanation of the high achievement levels in Japan. On the other hand, this extent of parental impact on the curriculum might be an indicator of the pressure parents put on schools to prepare their children appropriately for the entrance exams of senior high schools.In Table III, data on the extent of other types of parental involvement in Japan and other countries are given. In Japan, parental involvement is most common in case of schools volunteering for school projects and programs, and schools expecting parents to make sure that thechild completes his or her homework. The former is together with patrolling the grounds of the school to monitor student behavior most likely materialized through the PTA. The kinds and degree of activities of PTA vary according to the school, but the activities of the most active and well-organized PTA’s of 395 elementary schools investigated by Sumida (2001)range from facilitating sport and recreation for children, teaching greetings, encouraging safe traffic, patrolling the neighborhood, publishing the PTA newspaper to cleaning the school grounds (pp. 289–350). Surprisingly, less Japanese principals expect from the parents to check one’s child’s completion of homework than principals of other countries. In the discourse on the achievement gap, western observers report that parents and families in Japan provide more assistance with their children’s homework than parents and families outside Japan. This apparent contradiction might be the result of the fact that these data are measured at the lower secondary level while investigations of the roots of Japanese students’ high achievement levels focus on childhood education and learning at primary schools. In fact, junior high school students are given less homework in Japan than their peers in other countries and less homework than elementary school students in Japan. Instead, Japanese junior high school students spend more time at cram schools. Finally, Japanese principals also report very low degrees of expectations toward parents with regard to serving as a teacher aid in the classroom, raising funds for the school, assisting teachers on trips, and serving on committees which select school personnel and review school finances. The latter two items measure participation in school governance.In other words, the data support by and large the descriptions of parental of community involvement in Japanese schooling. Parents are requested to be supportive, but not to mount the territory of the teacher nor to be actively involved in governance. Moreover, whilst Japanese principals spend a few hours per month on communication toward the community, involvement from the community with regard to the curriculum is nearly absent, reflecting the nearly absence of accounts of community involvement in studies on Japanese education. However, the reader needs to be reminded that these data are measured at the lower secondary educational level when participation by parents in schooling decreases (Epstein, 1995; OECD, 1997; Osakafu Kyoiku Iinkai, unpublished report). Additionally, the question remains what stakeholders think of the current state of involvement in schooling. Some interesting local data provided by the Osaka Prefecture Education Board shed a light on their opinion.ReferencesBenjamin, G. R. (1997). Japanese lessons.

外文文献翻译原文Analysis of Con tin uous Prestressed Concrete BeamsChris BurgoyneMarch 26, 20051、IntroductionThis conference is devoted to the development of structural analysis rather than the strength of materials, but the effective use of prestressed concrete relies on an appropriate combination of structural analysis techniques with knowledge of the material behaviour. Design of prestressed concrete structures is usually left to specialists; the unwary will either make mistakes or spend inordinate time trying to extract a solution from the various equations.There are a number of fundamental differences between the behaviour of prestressed concrete and that of other materials. Structures are not unstressed when unloaded; the design space of feasible solutions is totally bounded;in hyperstatic structures, various states of self-stress can be induced by altering the cable profile, and all of these factors get influenced by creep and thermal effects. How were these problems recognised and how have they been tackled?Ever since the development of reinforced concrete by Hennebique at the end of the 19th century (Cusack 1984), it was recognised that steel and concrete could be more effectively combined if the steel was pretensioned, putting the concrete into compression. Cracking could be reduced, if not prevented altogether, which would increase stiffness and improve durability. Early attempts all failed because the initial prestress soon vanished, leaving the structure to be- have as though it was reinforced; good descriptions of these attempts are given by Leonhardt (1964) and Abeles (1964).It was Freyssineti’s observations of the sagging of the shallow arches on three bridges that he had just completed in 1927 over the River Allier near Vichy which led directly to prestressed concrete (Freyssinet 1956). Only the bridge at Boutiron survived WWII (Fig 1). Hitherto, it had been assumed that concrete had a Young’s modulus which remained fixed, but he recognised that the de- ferred strains due to creep explained why the prestress had been lost in the early trials. Freyssinet (Fig. 2) also correctly reasoned that high tensile steel had to be used, so that some prestress would remain after the creep had occurred, and alsothat high quality concrete should be used, since this minimised the total amount of creep. The history of Freyssineti’s early prestressed concrete work is written elsewhereFigure1:Boutiron Bridge,Vic h yFigure 2: Eugen FreyssinetAt about the same time work was underway on creep at the BRE laboratory in England ((Glanville 1930) and (1933)). It is debatable which man should be given credit for the discovery of creep but Freyssinet clearly gets the credit for successfully using the knowledge to prestress concrete.There are still problems associated with understanding how prestressed concrete works, partly because there is more than one way of thinking about it. These different philosophies are to some extent contradictory, and certainly confusing to the young engineer. It is also reflected, to a certain extent, in the various codes of practice.Permissible stress design philosophy sees prestressed concrete as a way of avoiding cracking by eliminating tensile stresses; the objective is for sufficient compression to remain after creep losses. Untensionedreinforcement, which attracts prestress due to creep, is anathema. This philosophy derives directly from Freyssinet’s logic and is primarily a working stress concept.Ultimate strength philosophy sees prestressing as a way of utilising high tensile steel as reinforcement. High strength steels have high elastic strain capacity, which could not be utilised when used as reinforcement; if the steel is pretensioned, much of that strain capacity is taken out before bonding the steel to the concrete. Structures designed this way are normally designed to be in compression everywhere under permanent loads, but allowed to crack under high live load. The idea derives directly from the work of Dischinger (1936) and his work on the bridge at Aue in 1939 (Schonberg and Fichter 1939), as well as that of Finsterwalder (1939). It is primarily an ultimate load concept. The idea of partial prestressing derives from these ideas.The Load-Balancing philosophy, introduced by T.Y. Lin, uses prestressing to counter the effect of the permanent loads (Lin 1963). The sag of the cables causes an upward force on the beam, which counteracts the load on the beam. Clearly, only one load can be balanced, but if this is taken as the total dead weight, then under that load the beam will perceive only the net axial prestress and will have no tendency to creep up or down.These three philosophies all have their champions, and heated debates take place between them as to which is the most fundamental.2、Section designFrom the outset it was recognised that prestressed concrete has to be checked at both the working load and the ultimate load. For steel structures, and those made from reinforced concrete, there is a fairly direct relationship between the load capacity under an allowable stress design, and that at the ultimate load under an ultimate strength design. Older codes were based on permissible stresses at the working load; new codes use moment capacities at the ultimate load. Different load factors are used in the two codes, but a structure which passes one code is likely to be acceptable under the other.For prestressed concrete, those ideas do not hold, since the structure is highly stressed, even when unloaded. A small increase of load can cause some stress limits to be breached, while a large increase in load might be needed to cross other limits. The designer has considerable freedom to vary both the working load and ultimate load capacities independently; both need to be checked.A designer normally has to check the tensile and compressive stresses, in both the top and bottom fibre of the section, for every load case. The critical sections are normally, but not always, the mid-span and the sections over piers but other sections may become critical ,when the cable profile has to be determined.The stresses at any position are made up of three components, one of which normally has a different sign from the other two; consistency of sign convention is essential.If P is the prestressing force and e its eccentricity, A and Z are the area of the cross-section and its elastic section modulus, while M is the applied moment, then where ft and fc are the permissible stresses in tension and compression.c e t f ZM Z P A P f ≤-+≤Thus, for any combination of P and M , the designer already has four in- equalities to deal with.The prestressing force differs over time, due to creep losses, and a designer isusually faced with at least three combinations of prestressing force and moment;• the applied moment at the time the prestress is first applied, before creep losses occur,• the maximum applied moment after creep losses, and• the minimum applied moment after creep losses.Figure 4: Gustave MagnelOther combinations may be needed in more complex cases. There are at least twelve inequalities that have to be satisfied at any cross-section, but since an I-section can be defined by six variables, and two are needed to define the prestress, the problem is over-specified and it is not immediately obvious which conditions are superfluous. In the hands of inexperienced engineers, the design process can be very long-winded. However, it is possible to separate out the design of the cross-section from the design of the prestress. By considering pairs of stress limits on the same fibre, but for different load cases, the effects of the prestress can be eliminated, leaving expressions of the form:rangestress e Perm issibl Range Mom entZ These inequalities, which can be evaluated exhaustively with little difficulty, allow the minimum size of the cross-section to be determined.Once a suitable cross-section has been found, the prestress can be designed using a construction due to Magnel (Fig.4). The stress limits can all be rearranged into the form:()M fZ PA Z e ++-≤1 By plotting these on a diagram of eccentricity versus the reciprocal of the prestressing force, a series of bound lines will be formed. Provided the inequalities (2) are satisfied, these bound lines will always leave a zone showing all feasible combinations of P and e. The most economical design, using the minimum prestress, usually lies on the right hand side of the diagram, where the design is limited by the permissible tensile stresses.Plotting the eccentricity on the vertical axis allows direct comparison with the crosssection, as shown in Fig. 5. Inequalities (3) make no reference to the physical dimensions of the structure, but these practical cover limits can be shown as wellA good designer knows how changes to the design and the loadings alter the Magnel diagram. Changing both the maximum andminimum bending moments, but keeping the range the same, raises and lowers the feasible region. If the moments become more sagging the feasible region gets lower in the beam.In general, as spans increase, the dead load moments increase in proportion to the live load. A stage will be reached where the economic point (A on Fig.5) moves outside the physical limits of the beam; Guyon (1951a) denoted the limiting condition as the critical span. Shorter spans will be governed by tensile stresses in the two extreme fibres, while longer spans will be governed by the limiting eccentricity and tensile stresses in the bottom fibre. However, it does not take a large increase in moment ,at which point compressive stresses will govern in the bottom fibre under maximum moment.Only when much longer spans are required, and the feasible region moves as far down as possible, does the structure become governed by compressive stresses in both fibres.3、Continuous beamsThe design of statically determinate beams is relatively straightforward; the engineer can work on the basis of the design of individual cross-sections, as outlined above. A number of complications arise when the structure is indeterminate which means that the designer has to consider, not only a critical section,but also the behaviour of the beam as a whole. These are due to the interaction of a number of factors, such as Creep, Temperature effects and Construction Sequence effects. It is the development of these ideas whichforms the core of this paper. The problems of continuity were addressed at a conference in London (Andrew and Witt 1951). The basic principles, and nomenclature, were already in use, but to modern eyes concentration on hand analysis techniques was unusual, and one of the principle concerns seems to have been the difficulty of estimating losses of prestressing force.3.1 Secondary MomentsA prestressing cable in a beam causes the structure to deflect. Unlike the statically determinate beam, where this motion is unrestrained, the movement causes a redistribution of the support reactions which in turn induces additional moments. These are often termed Secondary Moments, but they are not always small, or Parasitic Moments, but they are not always bad.Freyssinet’s bridge across the Marne at Luzancy, started in 1941 but not completed until 1946, is often thought of as a simply supported beam, but it was actually built as a two-hinged arch (Harris 1986), with support reactions adjusted by means of flat jacks and wedges which were later grouted-in (Fig.6). The same principles were applied in the later and larger beams built over the same river.Magnel built the first indeterminate beam bridge at Sclayn, in Belgium (Fig.7) in 1946. The cables are virtually straight, but he adjusted the deck profile so that the cables were close to the soffit near mid-span. Even with straight cables the sagging secondary momentsare large; about 50% of the hogging moment at the central support caused by dead and live load.The secondary moments cannot be found until the profile is known but the cablecannot be designed until the secondary moments are known. Guyon (1951b) introduced the concept of the concordant profile, which is a profile that causes no secondary moments; es and ep thus coincide. Any line of thrust is itself a concordant profile.The designer is then faced with a slightly simpler problem; a cable profile has to be chosen which not only satisfies the eccentricity limits (3) but is also concordant. That in itself is not a trivial operation, but is helped by the fact that the bending moment diagram that results from any load applied to a beam will itself be a concordant profile for a cable of constant force. Such loads are termed notional loads to distinguish them from the real loads on the structure. Superposition can be used to progressively build up a set of notional loads whose bending moment diagram gives the desired concordant profile.3.2 Temperature effectsTemperature variations apply to all structures but the effect on prestressed concrete beams can be more pronounced than in other structures. The temperature profile through the depth of a beam (Emerson 1973) can be split into three components for the purposes of calculation (Hambly 1991). The first causes a longitudinal expansion, which is normally released by the articulation of the structure; the second causes curvature which leads to deflection in all beams and reactant moments in continuous beams, while the third causes a set of self-equilibrating set of stresses across the cross-section.The reactant moments can be calculated and allowed-for, but it is the self- equilibrating stresses that cause the main problems for prestressed concrete beams. These beams normally have high thermal mass which means that daily temperature variations do not penetrate to the core of the structure. The result is a very non-uniform temperature distribution across the depth which in turn leads to significant self-equilibrating stresses. If the core of the structure is warm, while the surface is cool, such as at night, then quite large tensile stresses can be developed on the top and bottom surfaces. However, they only penetrate a very short distance into the concrete and the potential crack width is very small. It can be very expensive to overcome the tensile stress by changing the section or the prestress。

Criminal Law1.General IntroductionCriminal law is the body of the law that defines criminal offenses, regulates the apprehension, charging, and trial of suspected offenders,and fixes punishment for convicted persons. Substantive criminal law defines particular crimes, and procedural law establishes rules for the prosecution of crime. In a democratic society, it is the function of the legislative bodies to decide what behavior will be made criminal and what penalties will be attached to violations of the law.Capital punishment may be imposed in some jurisdictions for the most serious crimes. And physical or corporal punishment may still be imposed such as whipping or caning, although these punishments are prohibited in much of the world. A convict may be incarcerated in prison or jail and the length of incarceration may vary from a day to life.Criminal law is a reflection of the society that produce it. In an Islamic theocracy, such as Iran, criminal law will reflect the religious teachings of the Koran; in an Catholic country, it will reflect the tenets of Catholicism. In addition, criminal law will change to reflect changes in society, especially attitude changes. For instance, use of marijuana was once considered a serious crime with harsh penalties, whereas today the penalties in most states are relatively light. As severity of the penaltieswas reduced. As a society advances, its judgments about crime and punishment change.2.Elements of a CrimeObviously, different crimes require different behaviors, but there are common elements necessary for proving all crimes. First, the prohibited behavior designated as a crime must be clearly defined so that a reasonable person can be forewarned that engaging in that behavior is illegal. Second, the accused must be shown to have possessed the requisite intent to commit the crime. Third, the state must prove causation. Finally, the state must prove beyond a reasonable doubt that the defendant committed the crime.(1) actus reusThe first element of crime is the actus reus.Actus is an act or action and reus is a person judicially accused of a crime. Therefore, actus reus is literally the action of a person accused of a crime. A criminal statute must clearly define exactly what act is deemed “guilty”---that is, the exact behavior that is being prohibited. That is done so that all persons are put on notice that if they perform the guilty act, they will be liable for criminal punishment. Unless the actus reus is clearly defined, one might not know whether or not on e’s behavior is illegal.Actus reus may be accomplished by an action, by threat of action,or exceptionally, by an omission to act, which is a legal duty to act. For example, the act of Cain striking Abel might suffice, or a parent’s failure to give to a young child also may provide the actus reus for a crime.Where the actus reus is a failure to act, there must be a duty of care. A duty can arise through contract, a voluntary undertaking, a blood relation, and occasionally through one’s official position. Duty also can arise from one’s own creation of a dangerous situation.(2)mens reaA second element of a crime is mens rea. Mens rea refers to an individual’s state of mind when a crime is committed. While actus reus is proven by physical or eyewitness evidence, mens rea is more difficult to ascertain. The jury must determine for itself whether the accused had the necessary intent to commit the act.A lower threshold of mens rea is satisfied when a defendant recognizes an act is dangerous but decides to commit it anyway. This is recklessness. For instance, if Cain tears a gas meter from a wall, and knows this will let flammable gas escape into a neighbor’s house, he could be liable for poisoning. Courts often consider whether the actor did recognise the danger, or alternatively ought to have recognized a danger (though he did not) is tantamount to erasing intent as a requirement. In this way, the importance of mens rea hasbeen reduced in some areas of the criminal law.Wrongfulness of intent also may vary the seriousness of an offense. A killing committed with specific intent to kill or with conscious recognition that death or serious bodily harm will result, would be murder, whereas a killing affected by reckless acts lacking such a consciousness could be manslaughter.(3)CausationThe next element is causation. Often the phrase “but for”is used to determine whether causation has occurred. For example, we might say “Cain caused Abel”, by which we really mean “Cain caused Abel’s death. ”In other words, ‘but for Cain’s act, Abel would still be alive.” Causation, then, means “but for” the actions of A, B would not have been harmed. In criminal law, causation is an element that must be proven beyond a reasonable doubt.(4) Proof beyond a Reasonable DoubtIn view of the fact that in criminal cases we are dealing with the life and liberty of the accused person, as well as the stigma accompanying conviction, the legal system places strong limits on the power of the state to convict a person of a crime. Criminal defendants are presumed innocent. The state must overcome this presumption of innocence by proving every element of the offense charged against the defendant beyond a reasonable doubt to thesatisfaction of all the jurors. This requirement is the primary way our system minimizes the risk of convicting an innocent person.The state must prove its case within a framework of procedural safeguards that are designed to protect the accused. The state’s failure to prove any material element of its case results in the accused being acquitted or found not guilty, even though he or she may actually have committed the crime charged.3. Strict LiabilityIn modern society, some crimes require no more mens rea, and they are known as strict liability offenses. For in stance, under the Road Traffic Act 1988 it is a strict liability offence to drive a vehicle with an alcohol concentration above the prescribed limit.Strict liability can be described as criminal or civil liability notwithstanding the lack mens rea or intent by the defendant. Not all crimes require specific intent, and the threshold of culpability required may be reduced. For example, it might be sufficient to show that a defendant acted negligently, rather than intentionally or recklessly.1. 概述刑法是规定什么试犯罪,有关犯罪嫌疑人之逮捕、起诉及审判,及对已决犯处以何种刑罚的部门法。

The Stereo Garage1.1 An overview of the stereo garageVehicles parked nowhere is the problem of the urban social, economic and transport development to a certain extent the result, Garage Equipment development in foreign countries, especially in Japan nearly 30-40 years. Whether technically or in terms of experience had been a success. China is also in the beginning of the 1990s developed mechanical parking equipment, which was 10 years in the past. Because a lot of new residents in the district with the ratio of 1:1. To address the size of parking spaces for tenants and business areas contradictions 3D mechanical parking equipment with an average size of a small motorcycle's unique characteristics, the majority of users have been accepted.Compared with the traditional natural underground garage, Machinery garage demonstrates its superiority in many respects. First, the mechanical garage has a prominent section of superiority. Past due to the underground garage must elapse enough lanes, the average car will occupy an area of 40 square meters, If the use of double-mechanical garage, which would enable ground to improve the utilization rate of around 80% to 90%, If using ground multi-storey (21 storey), three-dimensional garage, 50 square meters of land area will be placed on the 40 cars, which can greatly save the limited land resources, Civil and save development costs.To underground garage, Mechanical garage can be more effective to ensure personal and vehicle safety in the garage or car kept prospective location, the entire electronic control equipment would not operate. It should be said that the mechanical garage from the management can do a thorough separation of people and vehicles.In the underground garage using mechanical parking, it also can remove the heating ventilation; therefore, Operation of the power consumption than workers in the management of underground garage is much lower. Mechanical garage don't usually do complete system, but as a single machine containers. This will give full play to its small space, the advantages of decentralized, Each of the residential areas or groups downstairs to make a complete circuit can be set up random mechanicalparking building. This garage of the district can solve the shortage of parking difficulty in providing convenient conditions right now.Currently, three-dimensional garage mainly in the following forms: lifting and transferring,aisle stacking garage, vertical garage, vertical cycle, box-level cycle, the level of circulating round.1.1.1 Lifting and transferringLifting and transferring Garage modular design, each module can be designed into two, three, four levels, the five-story, semi-submerged in various forms, such as the number of parking spaces from a few to hundreds. Three-dimensional garage applies to the ground and underground car parks, configuration flexibility and cost is low.1. Product features:1) Save land, the configuration flexibility, and shorter construction period.2) Low prices, firefighting and exterior decoration, with a total investment on small foundations.3) Use automatic control, simple structure, safe and reliable.4) Access to a quick, short waiting time.5) Run a smooth, low noise.6) Applies to commercial, offices, and residential quarters supporting the use of car parks.2. Safety devices: anti-dropping device, a photoelectric sensor, spacing protectors, emergency stop switch.1.1.2 Aisle stacking garageAisle stacking garage used as a stacking machine tool access vehicles. All vehicles are stacking machine access, so the technical requirements for stacker higher, a single stacker cost is higher. So aisle stacking apply to the parking garage needs a few more customers.1.1.3 Vertical GarageVertical Garage Elevator similar to the principle that both sides of the hoist layout spaces. Generally need a ground vehicle rotary tables can be saved by the driver away. Vertical Garage generally higher high (tens of meters), safety equipment, Installation precision machining requirements are very high, high cost, but has the smallest area.1.1.4 Vertical cycleProduct features:1) covers an area of small; two berths area can stop 6-10 vehicles.2) The decoration can be added only roof, fire hydrants available.3) Low prices, foundation, external decoration, fire and other small investment, short construction periods.4) Use automatic control, safe and reliable operation.2.2.1 The stereo garage automatic control systemThe modern large-scale building mainstream is intelligent mansion and community. So, automated parking equipment or garage automatic control system will become intelligent mansion and an important part of community. Simple, fast, easy to use, safe, reliable, and less maintenance, to provide users with a safe, easy to use environment, This is auto-parking feature of the basic equipment. All parking equipment operating conditions, vehicles parked in time, vehicle storage Malaysia, garage storage capacity. Vehicles kept high and low peaks, and other information can be transmitted through the network of intelligent control center through intelligent control center operator, and the broadcasting system and the management office of the Division linked related to early release control, management information, thus achieving all the intelligent management. Building and the Community through the intelligent control of the center could also associate with social networking functions. Information released to the collection coming out or expands utilization of the garage social and economic benefits. This will be the automation of the development direction of the garage.

Sampling is not used only in audit – is used in sampling surveys,market analysis and medical research in which someone wants to reach aconclusion about a large number of data by examining only a part of thesedata. The difference is the “population” from which the sample is selected, iethat set of data which is intended to draw a conclusion. Audit sampling appliesonly to certain types of audit procedures.Key words: sampling, sample risk, population, sampling unit, tests ofcontrols, substantive procedures.Statistical samplingCommittee statistical sampling of American Institute of CertifiedPublic Accountants of (AICPA) issued in 1962 a special report, titled“Statistical sampling and independent auditors’ which allowed the use ofstatistical sampling method, in accordance with Generally Accepted AuditingStandards (GAAS). During 1962-1974, the AICPA published a series of paperson statistical sampling, “Auditor’s Approach to Statistical Sampling”, foruse in continuing professional education of accountants. During 1962-1974,the AICPA published a series of papers on statistical sampling, “Auditor’sApproach to Statistical Sampling”, for use in continuing professional educationof accountants. In 1981, AICPA issued the professional standard, “AuditSampling”, which provides general guidelines for both sampling methods,statistical and non-statistical.Earlier audits included checks of all transactions in the period coveredby the audited financial statements. At that time, the literature has not givenparticular attention to this subject. Only in 1971, an audit procedures programprinted in the “Federal Reserve Bulletin (Federal Bulletin Stocks)” includedseveral references to sampling such as selecting the “few items” of inventory.Statistics and Audit The program was developed by a special committee, which later became the AICPA, that of Certified Public Accountants American Institute.In the first decades of last century, the auditors often applied sampling, but sample size was not in related to the efficiency of internal control of the entity. In 1955, American Institute of Accountants has published a study case of extending the audit sampling, summarizing audit program developed by certified public accountants, to show why sampling is necessary to extend the audit. The study was important because is one of the leading journal on sampling which recognize a relationship of dependency between detail and reliability testing of internal control.In 1964, the AICPA’s Auditing Standards Board has issued a report entitled “The relationship between statistical sampling and Generally Accepted Auditing Standards (GAAS)” which illustrated the relationship between the accuracy and reliability in sampling and provisions of GAAS.In 1978, the AICPA published the work of Donald M. Roberts,“Statistical Auditing”which explains the underlying theory of statistical sampling in auditing.In 1981, AICPA issued the professional standard, named “Audit Sampling”, which provides guidelines for both sampling methods, statistical and non-statistical.An auditor does not rely solely on the results of a single procedure to reach a conclusion on an account balance, class of transactions or operational effectiveness of the controls. Rather, the audit findings are based on combined evidence from several sources, as a consequence of a number of different audit procedures. When an auditor selects a sample of a population, his objective is to obtain a representative sample, ie sample whose characteristics are identical with the population’s characteristics. This means that selected items are identical with those remaining outside the sample.In practice, auditors do not know for sure if a sample is representative, even after completion the test, but they “may increase the probability that a sample is representative by accuracy of activities made related to design, sample selection and evaluation” [1]. Lack of specificity of the sample results may be given by observation errors and sampling errors. Risks to produce these errors can be controlled.Observation error (risk of observation) appears when the audit test did not identify existing deviations in the sample or using an inadequate audit technique or by negligence of the auditor.Sampling error (sampling risk) is an inherent characteristic of the survey, which results from the fact that they tested only a fraction of the total population. Sampling error occurs due to the fact that it is possible for Revista Română de Statistică nr. 5 / 2010Statistics and Auditthe auditor to reach a conclusion, based on a sample that is different from the conclusion which would be reached if the entire population would have been subject to audit procedures identical. Sampling risk can be reduced by adjusting the sample size, depending on the size and population characteristics and using an appropriate method of selection. Increasing sample size will reduce the risk of sampling; a sample of the all population will present a null risk of sampling.Audit Sampling is a method of testing for gather sufficient and appropriate audit evidence, for the purposes of audit. The auditor may decide to apply audit sampling on an account balance or class of transactions. Sampling audit includes audit procedures to less than 100% of the items within an account balance or class of transactions, so all the sample able to be selected. Auditor is required to determine appropriate ways of selecting items for testing. Audit sampling can be used as a statistical approach and a non- statistical.Statistical sampling is a method by which the sample is made so that each unit consists of the total population has an equal probability of being included in the sample, method of sample selection is random, allowed to assess the results based on probability theory and risk quantification of sampling. Choosing the appropriate population make that auditor’ findings can be extended to the entire population.Non-statistical sampling is a method of sampling, when the auditor uses professional judgment to select elements of a sample. Since the purpose of sampling is to draw conclusions about the entire population, the auditor should select a representative sample by choosing sample units which have characteristics typical of that population. Results will not extrapolate the entire population as the sample selected is representative.Audit tests can be applied on the all elements of the population, where is a small population or on an unrepresentative sample, where the auditor knows the particularities of the population to be tested and is able to identify a small number of items of interest to audit. If the sample has not similar characteristics for the elements of the entire population, the errors found in the tested sample can not extrapolate.Decision of statistical or non-statistical approach depends on the auditor’s professional judgment which seeking sufficient appropriate audits evidence on which to completion its findings about the audit opinion.As a statistical sampling method refer to the random selection that any possible combination of elements of the community is equally likely to enter the sample. Simple random sampling is used when stratification was not to audit. Using random selection involves using random numbers generated byRomanian Statistical Review nr. 5 / 2010Statistics and Audit a computer. After selecting a random starting point, the auditor found the first random number that falls within the test document numbers. Only when the approach has the characteristics of statistical sampling, statistical assessments of risk are valid sampling.In another variant of the sampling probability, namely the systematic selection (also called random mechanical) elements naturally succeed in office space or time; the auditor has a preliminary listing of the population and made the decision on sample size. “The auditor calculated a counting step, and selects the sample element method based on step size. Step counting is determined by dividing the volume of the community to sample the number of units desired. Advantages of systematic screening are its usability. In most cases, a systematic sample can be extracted quickly and method automatically arranges numbers in successive series.”[2].Selection by probability proportional to size - is a method which emphasizes those population units’recorded higher values. The sample is constituted so that the probability of selecting any given element of the population is equal to the recorded value of the item;Stratifi ed selection - is a method of emphasis of units with higher values and is registered in the stratification of the population in subpopulations. Stratification provides a complete picture of the auditor, when population (data table to be analyzed) is not homogeneous. In this case, the auditor stratifies a population by dividing them into distinct subpopulations, which have common characteristics, pre-defined. “The objective of stratification is to reduce the variability of elements in each layer and therefore allow a reduction in sample size without a proportionate increase in the risk of sampling.” [3] If population stratification is done properly, the amount of sample size to come layers will be less than the sample size that would be obtained at the same level of risk given sample with a sample extracted from the entire population. Audit results applied to a layer can be designed only on items that are part of that layer.I appreciated as useful some views on non-statistical sampling methods, which implies that guided the selection of the sample selecting each element according to certain criteria determined by the auditor. The method is subjective; because the auditor selects intentionally items containing set features him.The selection of the series is done by selecting multiple elements series (successive). Using sampling the series is recommended only if a reasonable number of sets used. Using just a few series there is a risk that the sample is not representative. This type of sampling can be used in addition to other samples, where there is a high probability of occurrence of errors. At the arbitrary selection, no items are selected preferably from the auditor, Revista Română de Statistică nr. 5 / 2010Statistics and Auditthat regardless of size or source or characteristics. Is not the recommended method, because is not objective.That sampling is based on the auditor’s professional judgment, which may decide which items can be part or not sampled. Because is not a statistical method, it can not calculate the standard error. Although the sample structure can be constructed to reproduce the population, there is no guarantee that the sample is representative. If omitted a feature that would be relevant in a particular situation, the sample is not representative.Sampling applies when the auditor plans to make conclusions about population, based on a selection. The auditor considers the audit program and determines audit procedures which may apply random research. Sampling is used by auditors an internal control systems testing, and substantive testing of operations. The general objectives of tests of control system and operations substantive tests are to verify the application of pre-defined control procedures, and to determine whether operations contain material errors.Control tests are intended to provide evidence of operational efficiency and controls design or operation of a control system to prevent or detect material misstatements in financial statements. Control tests are necessary if the auditor plans to assess control risk for assertions of management.Controls are generally expected to be similarly applied to all transactions covered by the records, regardless of transaction value. Therefore, if the auditor uses sampling, it is not advisable to select only high value transactions. Samples must be chosen so as to be representative population sample.An auditor must be aware that an entity may change a special control during the course of the audit. If the control is replaced by another, which is designed to achieve the same specific objective, the auditor must decide whether to design a sample of all transactions made during or just a sample of transactions controlled again. Appropriate decision depends on the overall objective of the audit test.Verification of internal control system of an entity is intended to provide guidance on the identification of relevant controls and design evaluation tests of controls.Other tests:In testing internal control system and testing operations, audit sample is used to estimate the proportion of elements of a population containing a characteristic or attribute analysis. This proportion is called the frequency of occurrence or percentage of deviation and is equal to the ratio of elements containing attribute specific and total number of population elements. WeightRomanian Statistical Review nr. 5 / 2010Statistics and Audit deviations in a sample are determined to calculate an estimate of the proportion of the total population deviations.Risk associated with sampling - refers to a sample selection which can not be representative of the population tested. In other words, the sample itself may contain material errors or deviations from the line. However, issuing a conclusion based on a sample may be different from the conclusion which would be reached if the entire population would be subject to audit.Types of risk associated with sampling:Controls are more effective than they actually are or that there are not significant errors when they exist - which means an inappropriate audit opinion. Controls are less effective than they actually are that there are significant errors when in fact they are not - this calls for additional activities to establish that initial conclusions were incorrect.Attributes testing - the auditor should be defining the characteristics to test and conditions for misconduct. Attributes testing will make when required objective statistical projections on various characteristics of the population. The auditor may decide to select items from a population based on its knowledge about the entity and its environment control based on risk analysis and the specific characteristics of the population to be tested.Population is the mass of data on which the auditor wishes to generalize the findings obtained on a sample. Population will be defined compliance audit objectives and will be complete and consistent, because results of the sample can be designed only for the population from which the sample was selected.Sampling unit - a unit of sampling may be, for example, an invoice, an entry or a line item. Each sample unit is an element of the population. The auditor will define the sampling unit based on its compliance with the objectives of audit tests.Sample size - to determine the sample size should be considered whether sampling risk is reduced to an acceptable minimum level. Sample size is affected by the risk associated with sampling that the auditor is willing to accept it. The risk that the auditor is willing to accept lower, the sample will be higher.Error - for detailed testing, the auditor should project monetary errors found in the sample population and should take into account the projected error on the specific objective of the audit and other audit areas. The auditor projects the total error on the population to get a broad perspective on the size of the error and comparing it with tolerable error.For detailed testing, tolerable error is tolerable and misrepresentations Revista Română de Statistică nr. 5 / 2010Statistics and Auditwill be a value less than or equal to materiality used by the auditor for the individual classes of transactions or balances audited. If a class of transactions or account balances has been divided into layers error is designed separately for each layer. Design errors and inconsistent errors for each stratum are then combined when considering the possible effect on the total classes of transactions and account balances.Evaluation of sample results - the auditor should evaluate the sample results to determine whether assessing relevant characteristics of the population is confirmed or needs to be revised.When testing controls, an unexpectedly high rate of sample error may lead to an increase in the risk assessment of significant misrepresentation unless it obtained additional audit evidence to support the initial assessment. For control tests, an error is a deviation from the performance of control procedures prescribed. The auditor should obtain evidence about the nature and extent of any significant changes in internal control system, including the staff establishment.If significant changes occur, the auditor should review the understanding of internal control environment and consider testing the controls changed. Alternatively, the auditor may consider performing substantive analytical procedures or tests of details covering the audit period.In some cases, the auditor might not need to wait until the end audit to form a conclusion about the effectiveness of operational control, to support the control risk assessment. In this case, the auditor might decide to modify the planned substantive tests accordingly.If testing details, an unexpectedly large amount of error in a sample may cause the auditor to believe that a class of transactions or account balances is given significantly wrong in the absence of additional audit evidence to show that there are not material misrepresentations.When the best estimate of error is very close to the tolerable error, the auditor recognizes the risk that another sample have different best estimate that could exceed the tolerable error.ConclusionsFollowing analysis of sampling methods conclude that all methods have advantages and disadvantages. But the auditor is important in choosing the sampling method is based on professional judgment and take into account the cost / benefit ratio. Thus, if a sampling method proves to be costly auditor should seek the most efficient method in view of the main and specific objectives of the audit.Romanian Statistical Review nr. 5 / 2010Statistics and Audit The auditor should evaluate the sample results to determine whether the preliminary assessment of relevant characteristics of the population must be confirmed or revised. If the evaluation sample results indicate that the relevant characteristics of the population needs assessment review, the auditor may: require management to investigate identified errors and likelihood of future errors and make necessary adjustments to change the nature, timing and extent of further procedures to take into account the effect on the audit report.Selective bibliography:[1] Law no. 672/2002 updated, on public internal audit[2] Arens, A şi Loebbecke J - Controve …Audit– An integrate approach”, 8th edition, Arc Publishing House[3] ISA 530 - Financial Audit 2008 - International Standards on Auditing, IRECSON Publishing House, 2009- Dictionary of macroeconomics, Ed C.H.

Mould is a product of high quality, high efficiency production tool, mold development cycle of the main part of the product development cycle. So the customer requirements for mold development cycle shorter, many customers put the mould delivery date in the first place, and then the quality and price. Therefore, how to ensure the quality, control the cost under the premise of processing mould is a problem worthy of serious consideration. Mold processing technology is an advanced manufacturing technology, has become an important development direction, in the aerospace, automotive, machinery and other industries widely used. Mold processing technology, can improve the comprehensive benefit and competitiveness of manufacturing industry. Research and establish mold process database, provide production enterprises urgently need to high speed cutting processing data, to the promotion of high-speed machining technology has very important significance. This article's main goal is to build a stamping die processing, mold manufacturing enterprises in theactual production combined cutting tool, workpiece and machine tool with the actual situation of enterprise itself accumulate to high speed cutting processing instance, process parameters and experience of high speed cutting database selectively to store data, not only can save a lot of manpower and material resources, financial resources, but also can guide the high speed machining production practice, to improve processing efficiency, reduce the tooling cost and obtain higher economic benefits.1. The concept, characteristics and application of stampingStamping is a pressure processing method that uses a mold installed on a press machine (mainly a press) to apply pressure to a material to cause it to separate or plastically deform, thereby obtaining a desired part (commonly referred to as a stamped or stamped part). Stamping is usually cold deformation processing of the material at room temperature, and the main use of sheet metal to form the required parts, it is also called cold stamping or sheet metal stamping. Stamping is one of the main methods of material pressure processing or plastic processing, and is affiliated with material forming engineering.The stamping die is called stamping die, or die. Dies are special tools for the batch processing of materials (metal or non-metallic) into the required stampings. Stamping is critical in stamping. There is no die that meets the requirements. Batch stamping production is difficult. Without advanced stamping, advanced stamping processes cannot be achieved.Stamping processes and dies, stamping equipment, and stamping materials constitute the three elements of stamping. Only when they are combined can stampings be obtained.Compared with other methods of mechanical processing and plastic processing, stamping processing has many unique advantages in both technical and economic aspects, and its main performance is as follows;(1) The stamping process has high production efficiency, easy operation, and easy realization of mechanization and automation. This is because stamping is accomplished by means of die and punching equipment. The number of strokes for ordinary presses can reach several tens of times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute, and each press stroke is Y ou may get a punch.(2) Since the die ensures the dimensional and shape accuracy of the stamping part during stamping, and generally does not destroy the surface quality of the stamping part, the life of the die is generally longer, so the stamping quality is stable, the interc hangeability is good, and it has “the same” Characteristics.(3) Stamping can process parts with a wide range of sizes and shapes, such as stopwatches as small as clocks, as large as automobile longitudinal beams, coverings, etc., plus the cold deformation hardening effect of materials during stamping, the strength of stamping and Thestiffness is high.(4) Stamping generally does not generate scraps, material consumption is less, and no other heating equipment is required. Therefore, it is a material-saving and energy-saving processing method, and the cost of stamping parts is low.However, the molds used for stamping are generally specialized, and sometimes a complex part requires several sets of molds for forming, and the precision of the mold manufacturing is high and the technical requirements are high. It is a technology-intensive product. Therefore, the advantages of stamping can only be fully realized in the case of large production volume of stamping parts, so as to obtain better economic benefits.Stamping is widely used in modern industrial production, especially in mass production. A considerable number of industrial sectors are increasingly using punching to process product components such as automobiles, agricultural machinery, instruments, meters, electronics, aerospace, aerospace, home appliances, and light industry. In these industrial sectors, the proportion of stamped parts is quite large, at least 60% or more, and more than 90%. Many of the parts that were manufactured in the past using forging = casting and cutting processes are now mostly replaced by light-weight, rigid stampings. Therefore, it can be said that if the stamping process cannot be adopted in production, it isdifficult for many industrial departments to increase the production efficiency and product quality, reduce the production cost, and quickly replace the product.2. Basic process and mould for stampingDue to the wide variety of stamped parts and the different shapes, sizes, and precision requirements of various parts, the stamping process used in production is also varied. Summarized, can be divided into two major categories of separation processes and forming processes; Separation process is to make the blank along a certain contour line to obtain a certain shape, size and section quality stamping (commonly referred to as blanking parts) of the process; forming process refers to The process of producing a stamped part of a certain shape and size by plastic deformation of the blank without breaking.The above two types of processes can be divided into four basic processes: blanking, bending, deep drawing and forming according to different basic deformation modes. Each basic process also includes multiple single processes.In actual production, when the production volume of the stamped part is large, the size is small and the tolerance requirement is small, it is not economical or even difficult to achieve the requirement if the stamping is performed in a single process. At this time, a centralized scheme is mostly used in the process, that is, two or more singleprocesses are concentrated in a single mold. Different methods are called combinations, and they can be divided into compound-graded and compound- Progressive three combinations.Composite stamping - A combination of two or more different single steps at the same station on the die in one press stroke.Progressive stamping - a combination of two or more different single steps on a single work station in the same mold at a single working stroke on the press.Composite - Progressive - On a die combination process consisting of composite and progressive two ways.There are many types of die structure. According to the process nature, it can be divided into blanking die, bending die, drawing die and forming die, etc.; the combination of processes can be divided into single-step die, compound die and progressive die. However, regardless of the type of die, it can be regarded as consisting of two parts: the upper die and the lower die. The upper die is fixed on the press table or the backing plate and is a fixed part of the die. During work, the blanks are positioned on the lower die surface by positioning parts, and the press sliders push the upper die downwards. The blanks are separated or plastically deformed under the action of the die working parts (ie, punch and die) to obtain the required Shape and size of punching pieces. When the upper mold is lifted, the unloading and ejecting device of the moldremoves or pushes and ejects the punching or scrap from the male and female molds for the next punching cycle.3. Current status and development direction of stamping technologyWith the continuous advancement of science and technology and the rapid development of industrial production, many new technologies, new processes, new equipment, and new materials continue to emerge, thus contributing to the constant innovation and development of stamping technology. Its main performance and development direction are as follows:(1) The theory of stamping and the stamping process The study of stamping forming theory is the basis for improving stamping technology. At present, the research on the stamping forming theory at home and abroad attaches great importance, and significant progress has been made in the study of material stamping performance, stress and strain analysis in the stamping process, study of the sheet deformation law, and the interaction between the blank and the mold. . In particular, with the rapid development of computer technology and the further improvement of plastic deformation theory, computer simulation techniques for the plastic forming process have been applied at home and abroad in recent years, namely the use of finite element (FEM) and other valuable analytical methods to simulate the plastic forming process of metals. According to the analysis results, the designer can predict the feasibility and possiblequality problems of a certain process scheme. By selecting and modifying the relevant parameters on the computer, the process and mold design can be optimized. This saves the cost of expensive trials and shortens the cycle time.Research and promotion of various pressing technologies that can increase productivity and product quality, reduce costs, and expand the range of application of stamping processes are also one of the development directions of stamping technology. At present, new precision, high-efficiency, and economical stamping processes, such as precision stamping, soft mold forming, high energy high speed forming, and dieless multi-point forming, have emerged at home and abroad. Among them, precision blanking is an effective method for improving the quality of blanking parts. It expands the scope of stamping processing. The thickness of precision blanking parts can reach 25mm at present, and the precision can reach IT16~17; use liquid, rubber, polyurethane, etc. Flexible die or die soft die forming process can process materials that are difficult to process with ordinary processing methods and parts with complex shapes, have obvious economic effects under specific production conditions, and adopt energy-efficient forming methods such as explosion for processing. This kind of sheet metal parts with complex dimensions, complex shapes, small batches, high strength and high precision has important practical significance; Superplastic forming of metal materialscan be used to replace multiple common stampings with one forming. Forming process, which has outstanding advantages for machining complex shapes and large sheet metal parts; moldless multi-point forming process is an advanced technology for forming sheet metal surfaces by replacing the traditional mold with a group of height adjustable punches. Independently designed and manufactured an international leading-edge moldless multi-point forming equipment, which solves the multi-point press forming method and can therefore be Changing the state of stress and deformation path, improving the forming limit of the material, while repeatedly using the forming technology may eliminate the residual stress within the material, the rebound-free molding. The dieless multi-point forming system takes CAD/CAM/CAE technology as the main means to quickly and economically realize the automated forming of three-dimensional surfaces.(2) Dies are the basic conditions for achieving stamping production. In the design and manufacture of stampings, they are currently developing in the following two aspects: On the one hand, in order to meet the needs of high-volume, automatic, precision, safety and other large-volume modern production, stamping is To develop high-efficiency, high-precision, high-life, multi-station, and multi-function, compared with new mold materials and heat treatment technologies, various high-efficiency, precision, CNC automatic mold processing machine toolsand testing equipment and molds CAD/CAM technology is also rapidly developing; On the other hand, in order to meet the needs of product replacement and trial production or small-batch production, zinc-based alloy die, polyurethane rubber die, sheet die, steel die, combination die and other simple die And its manufacturing technology has also been rapidly developed.Precision, high-efficiency multi-station and multi-function progressive die and large-scale complex automotive panel die represent the technical level of modern die. At present, the precision of the progressive die above 50 stations can reach 2 microns. The multifunctional progressive die can not only complete the stamping process, but also complete welding, assembly and other processes. Our country has been able to design and manufacture its own precision up to the international level of 2 to 5 microns, precision 2 to 3 microns into the distance, the total life of 100 million. China's major automotive mold enterprises have been able to produce complete sets of car cover molds, and have basically reached the international level in terms of design and manufacturing methods and means. However, the manufacturing methods and methods have basically reached the international level. The mold structure and function are also close to international Level, but there is still a certain gap compared with foreign countries in terms of manufacturing quality, accuracy, manufacturing cycle and cost.4. Stamping standardization and professional productionThe standardization and professional production of molds has been widely recognized by the mold industry. Because the die is a single-piece, small-volume production, the die parts have both certain complexity and precision, as well as a certain structural typicality. Therefore, only the standardization of the die can be achieved, so that the production of the die and the die parts can be professionalized and commercialized, thereby reducing the cost of the die, improving the quality of the die and shortening the manufacturing cycle. At present, the standard production of molds in foreign advanced industrial countries has reached 70% to 80%. Mould factories only need to design and manufacture working parts, and most of the mold parts are purchased from standard parts factories, which greatly increases productivity. The more irregular the degree of specialization of the mold manufacturing plant, the more and more detailed division of labor, such as the current mold factory, mandrel factory, heat treatment plant, and even some mold factories only specialize in the manufacture of a certain type of product or die The bending die is more conducive to the improvement of the manufacturing level and the shortening of the manufacturing cycle. China's stamp standardization and specialized production have also witnessed considerable development in recent years. In addition to the increase in the number of standard parts specialized manufacturers, the number ofstandard parts has also expanded, and the accuracy has also improved. However, the overall situation can not meet the requirements of the development of the mold industry, mainly reflected in the standardization level is not high (usually below 40%), the standard parts of the species and specifications are less, most standard parts manufacturers did not form a large-scale production, standard parts There are still many problems with quality. In addition, the sales, supply, and service of standard parts production have yet to be further improved.中文译文冲压模具技术前言在目前激烈的市场竞争中, 产品投入市场的迟早往往是成败的关键。

儿童教育外文翻译文献(文档含中英文对照即英文原文和中文翻译)原文:The Role of Parents and Community in the Educationof the Japanese ChildHeidi KnipprathAbstractIn Japan, there has been an increased concern about family and community participation in the child’s educat ion. Traditionally, the role of parents and community in Japan has been one of support and less one of active involvement in school learning. Since the government commenced education reforms in the last quarter of the 20th century, a more active role for parents and the community in education has been encouraged. These reforms have been inspired by the need to tackle various problems that had arisen, such as the perceived harmful elements of society’spreoccupation with academic achievement and the problematic behavior of young people. In this paper, the following issues are examined: (1) education policy and reform measures with regard to parent and community involvement in the child’s education; (2) the state of parent and community involvement at the eve of the 20th century.Key Words: active involvement, community, education reform, Japan, parents, partnership, schooling, supportIntroduction: The Discourse on the Achievement GapWhen western observers are tempted to explain why Japanese students attain high achievement scores in international comparative assessment studies, they are likely to address the role of parents and in particular of the mother in the education of the child. Education mom is a phrase often brought forth in the discourse on Japanese education to depict the Japanese mother as being a pushy, and demanding home-bound tutor, intensely involved in the child’s education due to severe academic competition. Although this image of the Japanese mother is a stereotype spread by the popular mass media in Japan and abroad, and the extent by which Japanese mothers are absorbed in their children is exaggerated (Benjamin, 1997, p. 16; Cummings, 1989, p. 297; Stevenson & Stigler, 1992, p. 82), Stevenson and Stigler (1992) argue that Japanese parents do play an indispensable role in the academic performance of their children. During their longitudinal and cross-national research project, they and their collaborators observed that Japanese first and fifth graders persistently achieved higher on math tests than American children. Besides reciting teacher’s teaching style, cultural beliefs, and organization of schooling, Stevenson and Stigler (1992) mention parent’s role in supporting the learning conditions of the child to explain differences in achievement between elementary school students of the United States and students of Japan. In Japan, children receive more help at home with schoolwork (Chen & Stevenson, 1989; Stevenson & Stigler, 1992), and tend to perform less household chores than children in the USA (Stevenson et al., 1990; Stevenson & Stigler, 1992). More Japanese parents than American parents provide space and a personal desk and purchase workbooks for their children to supplement their regular text-books at school (Stevenson et al., 1990; Stevenson & Stigler, 1992). Additionally, Stevenson and Stigler (1992) observed that American mothers are much more readily satisfied with their child’s performance than Asian parents are, have less realistic assessments of their child’s academic perform ance, intelligence, and other personality characteristics, and subsequently have lower standards. Based on their observation of Japanese, Chinese and American parents, children and teachers, Stevenson and Stigler (1992) conclude that American families can increase the academic achievement of their children by strengthening the link between school and home, creating a physical and psychological environment that is conducive to study, and by making realistic assessments and raising standards. Also Benjamin (1997), who performed ‘day-to-day ethnography’ to find out how differences in practice between American and Japanese schools affect differences in outcomes, discusses the relationship between home and school and how the Japanese mother is involved in the academic performance standards reached by Japanese children. She argues that Japanese parents are willing to pay noticeable amounts of money for tutoring in commercial establishments to improve the child’s performance on entrance examinations, to assist in ho mework assignments, to facilitate and support their children’s participation in school requirements and activities, and to check notebooks of teachers on the child’s progress and other school-related messages from the teacher. These booklets are read and written daily by teachers and parents. Teachers regularly provide advice and reminders to parents, and write about homework assignments of the child, special activities and the child’s behavior (Benjamin, 1997, p. 119, p. 1993–1995). Newsletters, parents’ v isits to school, school reports, home visits by the teacher and observation days sustain communication in later years at school. According toBenjamin (1997), schools also inform parents about how to coach their children on proper behavior at home. Shimahara (1986), Hess and Azuma (1991), Lynn (1988) and White (1987) also try to explain national differences in educational achievement. They argue that Japanese mothers succeed in internalizing into their children academic expectations and adaptive dispositions that facilitate an effective teaching strategy, and in socializing the child into a successful person devoted to hard work.Support, Support and SupportEpstein (1995) constructed a framework of six types of involvement of parents and the community in the school: (1) parenting: schools help all families establish home environments to support children as students; (2) communicating: effective forms of school-to-home and home-to-school communications about school programs and children’s progress; (3) volu nteering: schools recruit and organize parents help and support; (4) learning at home: schools provide information and ideas to families about how to help students at home with homework and other curriculum-related activities, decisions and planning; (5) decision making: schools include parents in school decisions, develop parent leaders and representatives; and (6) collaborating with the community: schools integrate resources and services from the community to strengthen school programs, family practices, and student learning and development. All types of involvement mentioned in studies of Japanese education and in the discourse on the roots of the achievement gap belong to one of Epstein’s first four types of involvement: the creation of a conducive learn ing environment (type 4), the expression of high expectations (type 4), assistance in homework (type 4), teachers’ notebooks (type 2), mother’s willingness to facilitate school activities (type3) teachers’ advice about the child’s behavior (type 1), observ ation days by which parents observe their child in the classroom (type 2), and home visits by the teachers (type 1). Thus, when one carefully reads Stevenson and Stigler’s, Benjamin’s and other’s writings about Japanese education and Japanese students’ high achievement level, one notices that parents’ role in the child’s school learning is in particular one of support, expected and solicited by the school. The fifth type (decision making) as well as the sixth type (community involvement) is hardly ever mentioned in the discourse on the achievement gap.In 1997, the OECD’s Center for Educational Research and Innovation conducted a cross-national study to report the actual state of parents as partners in schooling in nine countries, including Japan. In its report, OECD concludes that the involvement of Japanese parents in their schools is strictly limited, and that the basis on which it takes place tends to be controlled by the teacher (OECD, 1997, p. 167). According to OECD (1997), many countries are currently adopting policies to involve families closely in the education of their children because (1) governments are decentralizing their administrations; (2) parents want to be increasingly involved; and (3) because parental involvement is said to be associated with higher achievement in school (p. 9). However, parents in Japan, where students already score highly on international achievement tests, are hardly involved in governance at the national and local level, and communication between school and family tends to be one-way (Benjamin, 1997; Fujita, 1989; OECD, 1997). Also parent–teacher associations (PTA, fubo to kyoshi no kai ) are primarily presumed to be supportive of school learning and not to participate in school governance (cf. OECD, 2001, p. 121). On the directionsof the occupying forces after the second world war, PTA were established in Japanese schools and were considered with the elective education boards to provide parents and the community an opportunity to participate actively in school learning (Hiroki, 1996, p. 88; Nakata, 1996, p. 139). The establishment of PTA and elective education boards are only two examples of numerous reform measures the occupying forces took to decentralize the formal education system and to expand educational opportunities. But after they left the country, the Japanese government was quick to undo liberal education reform measures and reduced the community and parental role in education. The stipulation that PTA should not interfere with personnel and other administrative tasks of schools, and the replacement of elective education boards by appointed ones, let local education boards believe that parents should not get involved with school education at all (Hiroki, 1996, p. 88). Teachers were regarded to be the experts and the parents to be the laymen in education (Hiroki, 1996, p. 89).In sum, studies of Japanese education point into one direction: parental involvement means being supportive, and community involvement is hardly an issue at all. But what is the actual state of parent and community involvement in Japanese schools? Are these descriptions supported by quantitative data?Statistics on Parental and Community InvolvementTo date, statistics of parental and community involvement are rare. How-ever, the school questionnaire of the TIMSS-R study did include some interesting questions that give us a clue about the degree of involvement relatively compared to the degree of involvement in other industrialized countries. The TIMSS-R study measured science and math achievement of eighth graders in 38 countries. Additionally, a survey was held among principals, teachers and students. Principals answered questions relating to school management, school characteristics, and involvement. For convenience, the results of Japan are only compared with the results of those countries with a GNP of 20650 US dollars or higher according to World Bank’s indicators in 1999.Unfortunately, only a very few items on community involvement were measured. According to the data, Japanese principals spend on average almost eight hours per month on representing the school in the community (Table I). Australian and Belgian principals spend slightly more hours and Dutch and Singaporean principals spend slightly less on representing the school and sustaining communication with the community. But when it comes to participation from the community, Japanese schools report a nearly absence of involvement (Table II). Religious groups and the business community have hardly any influence on the curriculum of the school. In contrast, half of the principals report that parents do have an impact in Japan. On one hand, this seems a surprising result when one is reminded of the centralized control of the Ministry of Education. Moreover, this control and the resulting uniform curriculum are often cited as a potential explanation of the high achievement levels in Japan. On the other hand, this extent of parental impact on the curriculum might be an indicator of the pressure parents put on schools to prepare their children appropriately for the entrance exams of senior high schools.In Table III, data on the extent of other types of parental involvement in Japan and other countries are given. In Japan, parental involvement is most common in case of schools volunteering for school projects and programs, and schools expecting parents to make sure that thechild completes his or her homework. The former is together with patrolling the grounds of the school to monitor student behavior most likely materialized through the PTA. The kinds and degree of activities of PTA vary according to the school, but the activities of the most active and well-organized PTA’s of 395 elementary schools investigated by Sumida (2001)range from facilitating sport and recreation for children, teaching greetings, encouraging safe traffic, patrolling the neighborhood, publishing the PTA newspaper to cleaning the school grounds (pp. 289–350). Surprisingly, less Japanese principals expect from the parents to check one’s child’s completion of homework than principals of other countries. In the discourse on the achievement gap, western observers report that parents and families in Japan provide more assistance with their children’s homework than parents and families outside Japan. This apparent contradiction might be the result of the fact that these data are measured at the lower secondary level while investigations of the roots of Japanese students’ high achievement levels focus on childhood education and learning at primary schools. In fact, junior high school students are given less homework in Japan than their peers in other countries and less homework than elementary school students in Japan. Instead, Japanese junior high school students spend more time at cram schools. Finally, Japanese principals also report very low degrees of expectations toward parents with regard to serving as a teacher aid in the classroom, raising funds for the school, assisting teachers on trips, and serving on committees which select school personnel and review school finances. The latter two items measure participation in school governance.In other words, the data support by and large the descriptions of parental of community involvement in Japanese schooling. Parents are requested to be supportive, but not to mount the territory of the teacher nor to be actively involved in governance. Moreover, whilst Japanese principals spend a few hours per month on communication toward the community, involvement from the community with regard to the curriculum is nearly absent, reflecting the nearly absence of accounts of community involvement in studies on Japanese education. However, the reader needs to be reminded that these data are measured at the lower secondary educational level when participation by parents in schooling decreases (Epstein, 1995; OECD, 1997; Osakafu Kyoiku Iinkai, unpublished report). Additionally, the question remains what stakeholders think of the current state of involvement in schooling. Some interesting local data provided by the Osaka Prefecture Education Board shed a light on their opinion.ReferencesBenjamin, G. R. (1997). Japanese lessons.

华北电力大学毕业设计(论文)附件外文文献翻译学号: 200701000324 姓名:杨曦所在院系:电力工程系专业班级:电气化0707指导教师:安勃原文标题: Research on Smart Grid in China2011年06月20日对中国智能电网的研究1摘要——智能电网是电力系统的未来发展的新方向。

在本文中,首先是智能电网的背景,意义,以及概念和结构。

典型的智能电网图如下所示.然后,在美国和欧洲智能电网的发展现状进行了描述,并对这些国家未来发展思路的趋势进行了总结和比较及分析。

此外,分析了中国智能电网发展的必要性,详细介绍了在目前与中国与有关项目,并对特高压电网和智能电网之间的的关系进行了讨论。

最后,对智能电网在未来在中国电网的潜在作用进行了展望和并为中国的智能电网发展指明新方向.索引词,智能电网,特高压电网,规划,经营,管理一导言随着世界经济全球化的推广,石油价格一直维持在一个上升的趋势。

还值得注意的是世界范围内的的能源供应短缺,对资源和环境的压力越来越大,同时,由于目前电网的低效率,在能源输送过程中损失了巨大的电力。

此外,由于不断增长的电力需求和用户对电力可靠性和质量日益增长的要求,电力工业正面临着前所未有的挑战和机遇。

因此,一个有环境友好,经济,高性能,低投资,安全性,可靠性和灵活性特点的的电力系统一直是电力工程师的目标。

尽管如此,基础设施和先进的仪表出现互联网更广泛地的使用加速了这个过程[1]。

自1990年以来随着分布式发电越来越多地使用,已经对对电网的强度提出更多的需求和要求[2][3]。

对于这些问题,为了找出最佳的解决方案,电力公司应接受新的思路,采用新技术,对现有的能源系统进行潜力挖掘,对技术和应用加以改进。

来自不同国家的学者和专家已经达成共识:未来电网的必须能够满足不同的需求及能源发电,高度市场化的电力交易的需求,由此可以满足客户的自我选择。

所有这些都将成为未来智能电网的发展方向。

本文的重点是智能电网发展的现状,分析了智能电网的驱动力和也介绍中国当前的示范项目。

它也讨论了特高压电网和智能电网关系,并展望了在将来智能电网的意义。

智能电网中发展的一个新方向也被描绘,这可以为中国的智能电网的发展提供参考。

二智能电网概念智能电网是一个渐进发展的过程,伴随着随着技术创新,节约能源的需求和管理层的需要。

每个人都会有自己对的智能电网的理解,不管他们是设施供应商,IT公司,咨询公司,公共权力公司或发电公司。

从早先的智能电表到智能计量,从1Jingjing Lu, Da Xie, Member, IEEE and Qian Ai, Member, IEEE输电和配电自动化到全智能化过程中,智能电网的概念得到了极大程度的丰富[4]。

2006年,美国IBM公司提出了“智能电网"解决方案。

这是一个目前相对完整的概念,表明了智能电网的正式诞生[5]。

如图1所示,智能电网基本上覆盖了与信息系统与物理电源系统链接的设备及多种资产连同传感器,形成一个客户服务平台.它允许公用事业及消费者不断监测和调整用电。

公司经营管理将根据用户方和供应方能需求动态分析的基础上更加智能化和科学化,从而由于投资效率提高和更严格的设计标准优化电网资产的使用。

与传统电网相比,智能电网包括综合通信系统,先进的传感,计量,测量基础设施,完全决策支持和人性化界面.三目前的研究活动A:比较欧洲和美国智能电网领域的研究,在美国,近几年有几个大的电力中断事故,因此电力行业自身更加重视电力质量和可靠性,客户制定出电力供应更多的请求。

不断增长的需求和国环保政策要求对电网的建设与管理提出更高标准[6]。

与此同时,近年来,对基础材料,电力和信息技术,对已取得突破,表现出了了显着改善的可靠性及在电力网络的效率。

例如超导电缆的出现,让奥巴马对美国新政府已经看到了的智能电网的希望。

同样,欧洲也对电力供应与电能质量提出更高要求[7]。

由于对环境保护的极端重视,相对于美国的权力电网建设,欧洲人对建设更多的关注可再生能源的取得,对野生动物的影响,以及积极研究实时监测和终端控制。

一切都即将以“即插即用使用”的理念,确保对电网更加友好,灵活的访问与用户互动。

在欧洲和美国,为电网的发展寻求新能源和可再生来源发电是最常见的方向.然而,智能电网不是一个固定的,静态的项目,根据其特殊的地位和存在的主要问题,所有国家都需要简化智能电网,并使其调整到适合自己的特点。

B中国的智能电网发展的驱动力智能电网建设的推动力可以总结为市场,环境,安全和电能质量。

中国的电力行业也面临着类似的情况在欧洲和美国:以市场为导向的改革层面上,国家级的网络和全国统一的电力市场尚未完全形成。

从长远看来,中国的电力市场交易方式和价格结构都在发展,市场需求和供给双方将有更频繁的互动。

为了吸引更多的用户加入市场竞争,电力公司要改善服务,加强互动,用户和提供更多的产品供选择,以满足不同类型的用户的需求。

在宏观政策层面,电力行业需求,满足资源节约型,要求环保社会的建设,适应气候变化,促进可持续发展。

中国电网没有建成一个强大后盾的网络,而且还不能够承受多种故障情况。

区域骨干电网也是这样,稳定在一个较低的水平,在一个有限的系统操作中缺乏灵活性。

2008年初雪沙尘暴天气,导致了中国生动地面积停电,暴露了目前中国电网的电力供应保障方面的弱点。

此外,智能电源区域性分布缺乏,导致季节性电力短缺和既盈共存一些地区的电力。

仍然存在挑战,如何提高效率的电力投资和建设,如何确保安全和电网的运行可靠性,保证电能质量,如何提高维护电力系统的能力,如何提高服务质量,以及如何改善中国电网管理,对于这些问题,智能电网将是一个理想的解决方案。

C.目前在中国的研究活动2006年,IBM公司公布了'建立智能电网和创新管理方法---——对电力发展的新思路中国'命名的关于中国电力发展的新思路。

当前的机遇和挑战下建议中国电网公司加强对智能电网的建设和管理方法的创新,提高投资效率和电网建设,电网的稳定性,公司的服务和管理水平。

同时,IBM提出,它可以提供一个计划—能源解决方案架构(SAFT理论)来帮助中国电力公司有效的使用智能电网。

SAFT理论包含几个部分:第一是改善连接的设备与传感器数字水平;二是建立数据收集和整合系统;三是分析:SAFT在优化经营上改善的和数据分析基础上的管理。

这是在中国智能电网的未来的希望。

2007年10月,华东电网公司进行了区域智能电网可行性的研究。

这个研究项目,不仅相关这些先进企业和国外设施研究的进展,而且还需要考虑到华东电网采取的现状和未来。

结果是,在装备水平和较强的高技术创新能力的基础上,在华东建设智能电网是可行的。

华东电网公司在智能电网的建设上格将遵循“关于与未来的需求和变化速度快,提供优质服务”的信念。

目前有一个三步战略,2010年之前建立一个先进的电网输配中心, 2020年前建设完成有一定智能的数字电网,到2030年一个具有自我修复能力的智能电网建成[7].项目建设计划仍在考虑中。

2009年2月28日,作为华东智能电网的一部分,稳定状态,瞬态状态和动态状态作为安全防御的三态的和发电监控系统在北京通过了验收。

该系统第一次同时将三个简单的系统统一,其中包括电源管理系统,电网动态监测系统和网络的稳定性分析和预警系统.系统可以获得电网整体观运营状况并在不改变系统或平台的情况下作出决策.此外,该系统通过建立检查的管理平台和市场服务质量分析平台,有效地提高了管理的规范化和相关电厂电流等级。

中国的智能电网发展缓慢,远远落后于西方。

到目前为止,只有华东电网公司,南方电网公司和华北电网公司开展有关的研究开发和实施计划。

中国向来强调技术的发展,而事实上,在中国的设备制造先进于发达国家.因此,智能电网在中国有一个光明的前景。

四发展展望中国智能电网为了解决资源分配和电力负荷发电失衡问题的,通过建设长途和大容量电力传输系统,输电能力应该得到加强。

整体或者联合的特高压电网建设应根据协调好的计划建设.从中国西部和北部向中国中部和东部地区可以大规模的电力传输,减少在中国东部的能源和环境保护压力。

与此同时可以加速从资源优势向挥经济优势优势的转变,实现民族经济的协调发展.中国政治制度,经济环境和管理制度同样促进发展特高压电网。

目前,中国在研究未来的大电网的技术并具有构建全国统一电网能力。

在2009年1月16日,在中国首个特高压电力线已经完成,并投入运行。

统一或联合特高压电网,分布式电源或分散供电电网的是发展的趋势.中国,作为统一或联合特高压电网发展的典范,不同于任何西方国家。

在中国,同时发展特高压电网和智能电网是否存在矛盾?虽然大电网联动效应具有优化资源的优势,但它具有在大面积停电的潜在危险。

能够控制大功率电网并保持保持稳定的能力,是电网快速发展的要求.而智能电网自我修复和高可靠性就满足这样的要求。

因此,建设特高压电网和同时发展不同等级的电网,并改善经营和电网管理水平智能电网是中国电网的方向。

根据特高压前提和背景在当前中国电力电网的发展,这方面应更加重视对如下:智能规划:电网应逐渐具有自愈和智能的能力。

电网规划能力应该得到加强。

所以在特高压交/直流馈入不同电压等级协调发展的前提下,增加电网接收端能力。

最重要的是要转变观念和电力规划方法,并提出在传统基础上有所行长的概念,比如把建设新的变电站作为一个资源广泛的概念分布的资源分配端 .智能操作:调度模式为了增强控制和掌控大功率电网,在向着协调控制方向发展。

未来的智能电网为改善现有的在一个完整系统内的发动机管理系统,集成电力系统,定位系统功能和性能同时追查不同的电网监测和控制指标的相关关系, 并建立一个逻辑结构为基础的电力系统监测和控制指标体系,应该与具有先进管理能力的控制中心相协调。

通过渐进的过程的动态安全实施监测,电力系统预报警处理和预控,可以获取更精确和全面的数据,在此基础上,采取符合电力系统控制和调度最有效和及时措施和行动,最后,提高保障整个电力系统的稳定和安全。

智能管理:电源管理模式系统正在经历一个从垂直模式到分布式模式,从职能管理到流程管理,从电网建设大盘同时建设和运作模式的演变。

五总结智能电网是当今电力系统中的热点,也算是21世纪科技创新与发展的主要方面之一。

世界上许多国家都参与了这个大趋势,并建立了大量的智能电网示范项目和测试平台.此外,理论研究也在智能电网和实验研究取得了一些成就。

国际交流,极大地促进了智能电网的发展。

由于中国的电力输送及分布极不均衡用电负荷,这是一个正确的时间来发展特别高电压电网。

智能电网在我们国家仍然处于起步阶段的,如何结合特高压电网与智能电网是面临的主要问题。

中国智能电网的发展和特点仍有待我们的专家学者进一步研究探索。
