2.2客运服务和客运产品的关系
客运服务的层次:(菲利普·科特勒) 1.核心利益:无差别的旅客真正购买的服务和利益。(高铁客运服务的核心利益是”位移“) 2.基础产品:产品的基本形式与设备(列车、座位、铺位、卧具、卫生设备) 3.期望价值:旅客在购买服务时期期望得到的与服务密切相关的一整套属性和条件(列车运行安 全、卫生设施干净等)
服务业特点: 1、政府对服务业的管制放松 2、技术的进步 3、服务的全球化
1.2中国服务业发展历程及特点
• 1.1949-1978年——服务业在国民经济中所处地位 薄弱
• 2.1978年至今——私营个体经济重新介入经济活 动,服务行

业迅速增长
我国服务业在今后一段时期内仍将迅速增长的原因: 1.服务业在国民经济总值中所占的比重较低 2.服务业内部结构不合理 3.经济体制改革的推动力

2018学年高中数学北师大版必修一课件:第三章 指数函数与对数函数-第5节-5.3 精品

2018学年高中数学北师大版必修一课件:第三章 指数函数与对数函数-第5节-5.3 精品
y=lg x(x>0)的图像对称到 y 轴的左侧与函数 y=lg x 的图像合起来得函数 f(x)的 图像,如图所示.由图知:此函数是偶函数,f(x)>0 的解集为(-∞,-1)∪(1, +∞).
1.作函数图像的基本方法是列表描点法.另外,对形如 y=f(|x|)的图像可先 作出 y=f(x)的图像在 y 轴右侧的部分,再作关于 y 轴对称的图像,即可得到 y= f(|x|)的图像.y=|f(x)|的图像可先作出 y=f(x)的图像,然后 x 轴上方的不动,下 方的关于 x 轴翻折上去即可得到 y=|f(x)|的图像.
像,由底数变化对图像位置的影响知: log712>log812.
比较对数大小的思路: 1底相同,真数不同的,可看作同一对数函数上的几个函数值,用对数函 数的单调性比较大小; 2底数不同,真数相同的几个数,可通过图像比较大小,也可通过换底公 式比较大小; 3底不相同,真数也不相同的几个数,可通过特殊值来比较大小,常用的 特殊值是“0”或“1”.)
解惑:
比较大小
[小组合作型]
比较大小: (1)log0.31.8,log0.32.7; (2)log67,log76; (3)log3π,log20.8; (4)log7 12,log8 12.【导学号:04100063】
【精彩点拨】 (1)底数相同,可利用单调性比较;(2)与(3)可分别与“1”和“0” 比较大小;
2.如果只需要作出函数的大致图像时可采用图像变换.
[再练一题] 2.画出下列函数的图像,并根据图像写出函数的定义域与值域以及单调区 间:
(1)y=log3(x-2); (2)y=|log1x|.
2
【解】 (1)函数 y=log3(x-2)的图像可看作把函数 y=log3x 的图像向右平 移 2 个单位得到的,如图①.其定义域为(2,+∞),值域为 R,在区间(2,+∞) 上是增加的;

National Education Policiesand ProgrammesC o u n t r y Case Studies and Re s e a r c h1989-1999Education Se c t o rDivision for the Re c o n s t r uction and Deve l o p m e n tof Education Sy s t e msThe documents and publications referred to in this catalogue have been produced between 1989 and 1999 in the framework of UNESCO's education 'upstream' support services to Member States. They concern activities undertaken by or with support of BER/PSA (before 1996) and the ED/ERD Divisions designed to support the elaboration of sector-wide national policies, strategies and action plans for the reconstruction and reform of education systems in Member States in the framework of international development cooperation. Documents are related to country-based activities and, to a lesser degree, to cross-country activities under international working groups and partnerships.The database which serves for the elaboration of this catalogue is updated regularly and is available for consultation at the Office for Administration and Information of the Education Sector, UNESCO, Paris, as well as at UNESCO's field offices and education institutes throughout the world. It will also be made available through Internet at UNESCO (ED/ERD) Website in the near future. The documents themselves may be consulted at or requested from the Office for Administration and Information (ED/OAI) at UNESCO Paris Headquarters. The user should be aware of the special nature of this documentary collection which covers a broad variety of documents - from official government and agency documents and publications - to internal and working documents, frequently unofficial, and that they wary widely in quality, completeness and degree of reliability.Analysis and information presented in the individual documents are those provided by the authors and do not necessarily bear the endorsement of UNESCO.ED/99/WS/FOREWORDFor many years UNESCO has co-operated with other Agencies to assist its Member States in the preparation of suitable education projects for international co-operation and funding. This particular aspect of international co-operation is called the 'upstream' phase as it involves the analysis of the educational situation, the definition of country policies and strategies, the drawing up of plans, programmes and projects prior to their actual launching under what is generally referred to as the 'downstream" phase.Since the 1980s, UNESCO has intensified its efforts to provide 'upstream' services to the Member States in response to the changing conditions in international development co-operation. This co-operation is increasingly focussed on sector-wide policies as opposed to the traditional sub-sector and individual projects approaches. At the same time a large number of countries are increasingly dependant on external financing for their educational investments, particularly the Least Developed Countries. Those countries are doubly dependant on external funding agencies, in particular the World Bank, which holds a leading position both from the financial and technical assistance points of view. In this context multilateral and bilateral funding agencies are often perceived as wielding undue influence on the agenda for national policy analysis and formulation as well as on the investments made by other Organizations and external partners.In the area of upstream work, UNESCO has earned a reputation as an "honest broker' for its professional independence and sensitivity to the interests of the countries it is servicing.A specific unit for the provision of upstream services was created at UNESCO Headquarters in 1990 in order to respond adequately to the growing demand for such services and was subsequently integrated into the Education Sector in 1996, as part of the Division for the Reconstruction and Development of Education Systems (ED/ERD). The aim was to support national leadership in the preparation of national strategies and action plans, as well as in the mobilisation of national and external resources, both intellectual and financial, which are required for sound and independent policy analyses work. Emphasis is placed on national capacity building, enhancing negotiation skills for policy dialogue and donor co-ordination.UNESCO has provided education upstream services to well over 30 Member States during the present decade, with special attention being paid to the Least Developed Countries in Africa and South East Asia, as well as to countries undergoing rapid political and economic transition or in post-conflict reconstruction. In recent years, upstream activities have been broadened to encompass several complementary cross-country initiatives, such as the regional Working Group on Education Sector Analysis (WGESA) within the framework of the Association for the Development of Education in Africa (ADEA), as well as inter-agency partnerships on educational reform and international co-operation.The present catalogue contains bibliographical references of those working documents and research publications produced from 1989 to 1999, either by or with the support of the former division for Policies and Sector Analysis (BER/PSA) before its integration into the ED Sector in 1996 and the ED/ERD Division, as part of UNESCO's education upstream support services to Member States.The catalogue is primarily addressed to professionals, researchers and students undertaking field research and operational work related to the elaboration of national education policies and programmes within the framework of development co-operation. Although it includes numerous unofficial and internal working papers which vary widely in quality, form or presentation it provides a wealth of methodological, historical and contextual data which we hope will prove useful for information and research purposes. It is also hoped that this initiative will contribute to increasing the dissemination and utilization of field-related information and analysis in international co-operation.Lucila Jallade M.

Project documents retained in this catalogue concern selected country upstream services and may be used as practical examples for the development of further projects in similar areas.2.Country Sector Reviews and StudiesSector-wide reviews and /or analyses of the education system in a given country (in-depth briefs, needs-assessment report). Usually they provide a synthetic view of the sector, including statistical and institutional information, identification and analysis of issues as well as the priority areas for educational development.3.Country Sub-Sectoral/Thematic StudiesAs above but covering a specific sub-sector or theme. These studies usually serves as inputs for sector-wide reviews. Most internal national and international consultancy reports fall under this category.4.Country Policy/Strategy Documents and Action PlansPresentation of national policy or strategy and /or action plans or programme for the development of the education sector or a sub-sector in a given country. They may include detailed action or investment plans with related costing and a summary of the sector or sub-sector situation as well as the related statistical information. Documents submitted to donor round tables/consultations are included in this category.5.Mission ReportsReports produced by UNESCO staff or consultants upon return from missions to a given country undertaken in connection with upstream projects and studies. They refer to the mission's context and activities, present follow-up proposals and frequently provide a preliminary substantive report on a given subject.6.Project Reviews and Evaluation/Final ReportsDescriptive and/or analytical reports on the progress, results and lessons learnt from a given project.7.Training/Workshop MaterialsSpecific documentation concerning training activities, national workshops and seminars undertaken in connection with upstream activities.8.Other project based documents and miscellaneousOther documents not elsewhere classified.9.Publication/Research/Methodology PapersCase studies, generic and or reflective papers and publications referring to international experience in the field of education sector analysis, educational policy and programme development, international aid and related subjects. Most of the papers are closely connected to the experience resulting from the projects and documents listed in the catalogue and database. They may directly refer to one region, sub-region or country.KEYWORDS AAction planAdult educationAfrica regionAsian regionALBANIAAuditsAusterityBBasic educationBENINBilateral agencies BOSNIA AND HERZEGOVINA BURKINA FASOCCAMBODIACapacity buildingCHADCOMOROS Comparative education CONGOCONGO DRContinuing education CurriculumDDecentralisation DemographyDeveloping countries Development aidDonors coordination DropoutsEEducation sector analysis Educational administration Educational costs Educational decentralization Educational evaluation Educational facilities Educational finance Educational innovations Educational management Educational management information system Educational organisation Educational personnel Educational planning Educational policy Educational policy analysis Educational projects Educational reconstructionEducational qualityEducational reformEducational researchEducational statisticsEducational strategiesEducational supervisionEducational systemsEmploymentETHIOPIAExternal aidFFunctional analysisGGABONGeneral educationGHANAGUINEAHHAITIHigher educationHuman developmentHuman resources developmentIInstitutional developmentInternational developmentcooperationInternational educationInter-regional issuesInvestment plan/programmeLLeast developed countriesLEBANONLESOTHOLiteracyMMacro-economic frameworkMADAGASCARMALIMaster planMAURITANIAMAURITIUSMOROCCOMOZAMBIQUEMultilateral agenciesMultilateralismMYANMARNNonformal educationNon-governmental organisationPPALESTINEPAPUA NEW GUINEAPedagogyPoverty alleviationPre-school educationPrimary educationPrivate educationRRWANDASSAO TOME AND PRINCIPESchool mappingScience educationSecondary educationSENEGALSimulation modelSkills developmentSocio-economic contextSocio-economic indicatorsSOUTH AFRICASpecialised educationSRI LANKAStructural adjustmentSUB-SAHARAN AFRICATTeacher educationTeacher effectivenessTeacher trainingTeaching materialsTeaching staffTechnical and vocationaleducationTextbooksTripartite reviewVVIETNAMVocational trainingWWomen educationWorkshop materialsZZIMBABWEDOCUMENTS BY COUNTRYALBANIA / ALBANIE1Albania: Education Donors Consultation.
