模拟国际会议发言稿【篇一：模拟国际会议演讲稿】recsplorer:recommendation algorithms based on precedence mining1. introductionthank you very much, dr. li, for your kind introduction. ladies and gentlemen, good morning! i am honored to have been invited to speak at this conference. before i start my speech, let me ask a question. do you think recomemdations from others are useful for your internet shopping? thank you. it is obvious that recommendations play an important role in our daily consumption decisions.today, my topic is about recommendation algorithms based on precedence mining. i want to share our interesting research result on recommendation algorithms with you. the content of this presentation is divided into 5 parts: in session 1, i will intruduce the tradictional recommendation and our new strategy; in session 2, i will give the formal definition of precedence mining; in session 3, i will talk about the novel recommendation algorithms; experimental result will be showed in session 4; and finally, i will make a conclusion.2. bodysession 1: introductionthe picture on this slide is an instance of recommemdation application on amazon.recommender systems provide advice on products, movies,web pages, and many other topics, and have become popular in many sites, such as amazon. many systems use collaborative filtering methods. the main process of cf is organized as follow: first, identify users similar to target user; second, recommend items based on the similar users. unfortunately, the order of consumed items is neglect. in our paper, we consider a new recommendation strategy based on precedence patterns. these patterns may encompass user preferences, encode some logical order of options and capture how interests evolve.precedence mining model estimate the probability of user future consumption based on past behavior. and theseprobabilities are used to make recommendations. through our experiment, precedence mining can significantly improve recommendation performance. futhermore, it does not suffer from the sparsity of ratings problem and exploit patterns across all users, not just similar users.this slide demonstrates the differences between collaborative filtering and precedence mining. suppose that the scenario is about course selection. each quarter/semester a student chooses a course, and rates it from 1 to 5. figure a) shows five transcripts, a transcript means a list of course. u is our target student who need recommendations. figure b) illustrates howcf work. assume similar users share at least two common courses and have similar rating, then u3 and u4 are similar to u, and their common course h will be a recommendation to u. figure c) presents how precedence mining work. for this example, we consider patterns where one course follows another. suppose patterns occour at least two transcrips are recognized as significant, then (a,d), (e,f) and (g,h) are found out. and d, h, and f are recommendation to u who has taken a, g and e.now i will a probabilistic framework to solve the precedence mining problems. our target user has selected course a , we want to compute the probability course x will follow, i.e.,pr[x|a].﹁howerve, what we really need to calculate is pr[x|ax] rather than pr[x|a]. because in our context,we are deciding if x is a good recommendation for the target user that has taken a. thus we know that our target user’s transcript does not have x before a. for instance, the transcript no. 5 will be omitted. in more common situation, our targetuser has taken a list of courses, t = {a,b,c,…} not﹁just a. thus, what really need is pr[x|tx]. the question is how to figure out this probability. i willanswer it later.session 2: precedence miningwe consider a set d of distinct courses. we use lowercase letters (e.g., a, b, … ) to refer to courses in d. a transcript t is a sequence of courses, e.g., a - b - c - d. then the definition oftop-k recommendation problem is as follows. given a set transcripts over d for n users, the extra transcript t of a targetuser, and a desired number of recommendations k, our goal is to:1. assign a score score(x) (between 0 and 1) to every course x ∈ d that reflects how likely it is the target student will be interested in taking x. if x ∈ t , then score(x) = 0.2. using the score function, select the top k courses to recommend to the target user.to compute scores, we propose to use the following statistics, where x, y ∈ d:f(x): the number of transcripts that contain x.g(x; y): the number of transcripts in which x precedes course y.this slide shows the calculation result of f(x) and g(x,y). for example, from the table, we know that f(a) is 10 and g(a,c) is 3. we propose a precedence mining model to solve the top-k recommendation problem. here are﹁some notation: xy, which we have memtioned in session 1, refers to transcript where x occurswithout a preceding y; x﹁y refers to transcript where x occurs without y following it. we use quantities f(x) and g(x,y) to compte probabilities that encode the precedence information. for instance, from formular 1 to 7. i would not tell the detail of all formulars. we just pay attention to﹁formular 5, note that this quantity above is the same as: pr[x ﹁y |yx] which will be used toas we know, the target user usually has taken a list ofcourses rather than a course, so we need to﹁extent our probability calculation formulars. for example, suppose t={a,b}, pr[xt] theprobability x occurs without either an a or b preceding it; pr[x﹁t] the probability x occurs without either an a or b following it. this probability can be calculated exactly. so how to calculate it?session 3: recommendation algorithmslet’s review session 2. the main goal of the recommendation algorithms is to calculate the score(x), and then select the top k courses based on these scores. traditional recommendation algorithms compute a recommendation score for a course x ind only based on its frequency of occurence. it does not take into account the courses taken by the target user.our recommendation algorithms called singlemc conquer the shortcoming of the traditional ones. it computes the score(x) using the formular 5. the detail is as follows: a student with a transcrip t of taken courses, for the course y ∈ t, if y and x appear together in transcripts satisfies the﹁and ignoring the effect of the other courses in t; finally the maximum of pr[x﹁y |yx] is choosen asthe score(x).here is the calculation formular of score(x) of signlemc. for example, with the higer score, d will be recommended.another new recommendation algorithm named joint probabilities algorithm, jointp for short, is proposed. unlike singlemc, jointp takes into account the complete set of courses in a transcript. in formular 12, we cannot compute its quantity exactly, remember this problem we have mentioned. our solution is to use approximations. this slide is about the first approximating formular. and this the second approximating formular.the system is courserand, and data set for experiment contains 7,500 transcripts.this slide shows the new recommendation algoritms with black color and the traditional ones with blue color.the chart on this slide indicates our new recommendation algorithms beat the traditional ones in precision, because the former ones exploit patterns across all users, while the latter ones just use the similar users.the chart on this slide points out our new recommendation algorithms also beat the traditional ones in coverage for the same reason.session 5: conclusion and summaryin conclusion, we proposed a novel precedence mining model, developed a probabilistic framework for making recommendations and implemented a suite of recommendation algorithms that use the precedence information. experimental result shows that our new algorithms perform better than the traditional ones, and our recommendation system can be easily generalized to otherscenarios, such as purchases of books, dvds and electronic equitment.to sum up, first, i introduced the motivation and the outline of work; second, i gave the definition of precedence mining model; third, i described some new recommendation algorithms using precedence information; forth, i showed our experimental results to compare the new algorithms with traditional ones. finally, i made a conclusion of our work.. that’s all. thank you! are there any questions?【篇二：国际会议作报告英语发言稿】thank you, prof. …. my name is ….. i’m from ….. i am very pleased to be here to join this forum. the topic of my presentation is properties of rapid construction materials for soil pavement of field airfield. as is shown in the picture, the main parts of my research are about soil pavement.my presentation will include these four parts:first, some background information about this research; second, the main work we have done; third, some conclusions we have got and the last: innovation and presentation of our published papers.why i choose this item? i think it can be illustrated from the following four parts. first, the existing quantity of airfields is still not sufficient and the airfields have many shortcomings especially in war time. second, the complementary facilities, such as highway runways are far less than airfields, however, have more weakness. third, a certain amount of field airfield is quite necessary considering some emergencies such as rescue and disaster relief. forth, the field airfield can fill the void of airfield and they can be combined to be airfield network. the meaning and aim of this research contains three parts. fast, convenient and validity, fast means the field airfield must be constructedas fast as possible, convenient means the construction should need the minimum equipment, labor and materials considering the actual construction condition, validity means the constructed airfield is able to support the operation of given aircraft in specifically time.just like many other territories, the situation of the research is that the u.s. army takes advanced line. the u.s. army declaresthat they can reach to anywhere on the earth in 96 hours, the most important method for force projection is though aircraft, thus rapid construction of pavement is the key problem for rapid force transportation.the main work we have done can be summarized as four parts, materials choosing, scheme making, mechanical properties research and water-stable properties research.we choose two kinds of soils, which are got from xi’an,shanxi province and jiuquan, gansu province separately. the sand from ba river was considerate to investigate the influence of sand to the properties of stabilized soil. the chosen three kinds of powders are cement, lime and new-type stabilizer developed by chang’an university. the principles in considering the function of 4 kings of fibers are referring different length, type and mixing them.on account of the time, i will make a brief description aboutthe experiment scheme. in summary, three parts were proposed to distinguish the affecting factors in making experiment scheme. they are powder control, fiber control and other factors. taking powder control for example, the dosage of cement is respectively 6%, 8% and 10% when the soil is stabilized only by cement, while the dosage of cement decrease to 3%, 5% and 7% when the lime is addicted to stabilized soil. the following two factors are stabilizer and sand. six kinds of experiments were performed to investigate the influence of above factors to the mechanical properties of stabilized soil. the aim of compaction test is to find the maximum dry density and optimum moisture content. the aim of compression strength test is to determine the optimum dosage of cement, lime, powder stabilizer and fiber, meanwhile evaluating the performance of stabilized soil. the aim of splitting tension strength test is similar to compression strength test, the left picture is sample stabilized by cement, while the right picture is the sample stabilized by fiber and cement. the direct sheer is another important parameter in geotechnical engineering. it influences the foundation bearing capacity and many other properties especially for soil baseand base course. the left picture shows the course of making sample and the right picture shows the test process.the cbr test and rebound modulus test are referenced from highway test specification to evaluating the comprehensive capacities of each structure level of the pavement. for both the two tests, the left picture shows the course of making sample and the right picture shows the test process. what should be noted is that the number of sample is at least 6, the last result is the average value of these date got from test after eliminating the bad results.four kinds of experiments were performed to investigate the influence of above factors to the water-stable properties of stabilized soil. the scouring test is not the stated experiment in current specification. it is performed by us through looking up large quantity of interrelated literature, and two different ways to carry out. the left picture shows the method of vibration table and the right picture shows the method of fatigue test instrument. penetrant test refers to the experiment in relating concrete specification. the left picture shows the process of saturation, the right picture shows the test process.cantabria test and other tests are all original experiments; they are used in stabilized soil for first time, here i will not develop my narrative.as regards the innovation, i think it throughout the whole research, including materials choosing, scheme making, mechanical and water-stable experiments. i think it can be drawled from the following keywords, such as soil choosing, sand, powders, fibers, and so on. three main parts can be summarized. first, selecting two kinds of soils, three kinds of powders, several combinations; second, several kinds of fibers, different length and admixture; third, comprehensive experiments, test method and test instrument.【篇三：国际学术会议发言稿】1. prologuethank you, mr. chairman, for your gracious introduction. i am honored to have the chance to address you on this special occasion. the topic of my paper is “transaction cost and farmers’choice of agricultural products selling”. the outline of my talk as follows. the first part i want to introduce the background of this research. the second part suggests a simple household choice model .the third part covers the dataused in this research. and then, we introduce the empirical results. finally, a simple conclusion is given.2. introductionwell, let’s move on the first part of this topic .the motivation of this work like this. institutional economics posits that agents making decisions on different types of transactions do so in a costly way .for example , farmers deciding sell a particular crop to whom base their decisions not only on the price they expect to receive in each market choice but also on additional costs related to transacting in these markets.i want to use a picture to illustrate it. for example, given some market channels, farmers’ choices can be regarded as equilibrium between the surplus and the additional costs that related to transacting .especially in developing countries, high-value crop producers fully participate in the market and the transaction cost has been the hard constraint to farmers. furthermore, farmers’ market choices can be taken as a choice dilemma of transaction cost and production surplus. consequently, the scientific question of this research is how transaction cost affects planters’ choices.3. methodologyq?n?market. the third equationi ? q ? implies the amount exchanged in nth time.in stage 3, farmers will decide to sell the products to whom.c hanel j’s market price isbdecided by an exogenesis price and farmers’ negotiating power. pij?p*j?b(qi,zi)besides this, we use a matrix to show the net profit of chanel jx ik ? ik , ? ?? ik ?and then farmers’ choice can be expressed in a typical choi ce modelexp(xij?)pr(ji?j|xik)?1 exp(xij?)? k?1based on the choice model, another important concept is famers’ channel choice .here, we set five types .they rank by the market barriers. accordingly, we set a group discrete number to express them. y: dependent variable y=5,means farmer choosebrokers. y=1, farmers sell products to consumers directly.4. data and estimation procedureshere, we illustrate the data distribution with this map. according to the agricultural regionalization from department of agriculture, the apple specialization areas in china contain two parts: bo sea area and loess plateau. bo sea area in red color, contains hebei, shandong and liaoning 3 provinces. and loess plateau in green color, contains shanxi, henan, shaanxi and gansu 4 provinces. firstly, we use pps method to get the first stage sampling unit 14 counties in 7 provinces. then use random sample method to get village and household. they are our sample distribution.5. empirical results6. conclusions。

We have had 6 reports presented. Thank you for your informative talks, and thank you for your interesting questions and answers during the Q & A Session. We have shared much experience and knowledge. All of us have learned a lot about the recent achievements and up-to-date information in our research field. I believe this is a very successful meeting. I hope we can go on with our stimulated international conference tomorrow. Let us meet again here in the same room at 2:00 tomorrow afternoon.As a spesker:Since my partner have talked about the details about the methods and results of our experiment ,now ,i would like to some disadvantage in the process of expeiment ,i have 6 points to cover in the discussion part.first ,regression models showed that driver mutations are able to explain a limited fraction of the total variation of the most relevant clinical variables.second,However, we also found that recurrent somatic mutations were able to explain only a fraction of the total variation of the most relevant clinical variables, including hemoglobin, WBC count and BM blasts.then,Although the integration of cytogenetic abnormalities resulted in a better risk stratification, only a minority of CMML patients carry recurrentkaryotypic abnormalities. Several genes were reported to have prognostic value in CMML.It must be acknowledged that our sample size did not allow to assess possible interactions between co-occurring mutations, which may potentially influence the resulting compounded prognostic effect.As previously observed for the original CPSS, comparable results were obtained when the scoring system was calculated using hemoglobin thresholds instead of RBC transfusion-dependency.13 This alternative model could be useful, especially in those patients deserving urgent therapy and in whom RBC transfusion-dependency is still not established.In conclusion, although current understanding of the pathophysiology of CMML at present does not allow to move toward entirely molecular-based classification and risk assessment, the results of this study suggest that the integration of somatic mutations significantly improve prognostic stratification of patients with this neoplasm, and may provide a basis for improving clinical decision-making.。

模拟国际会议演讲稿
1.IntroductionThank you very much.Mr.Jiao,for your kind dies and gentlemen,Good afternoon!My name is Lijia,came from Harbin Engineering University.I am honored to have been invited to speak at this conference.Before I start my speech,let me ask a question.Do you know what can affect the properties of foam concrete?Do you think how to reinforced the properties of foam concrete？Most of the investigations on foam concrete in the past have been confined（被限于）to neat cement paste,cement paste with partial replacement with admixtures and to cement–sand mixes.Today,my topic is about Influence offiller type on the properties of foam concrete.I want to share our interesting research result on reinforced concrete frame with you.The content of this presentation is divided into4parts:In section1,I will introduce what is the foam concrete.In section2,I will talk about Parameters investigated and mix compositions.In section3,I will give Effect of water–solids ratio on design density.And finally,I will make a conclusion.2.BodySection1:the foam concreteNow,I will introduce the foam concrete.Pre-formed(成型的)foam concrete is manufactured（加工）by adding foam,prepared by aerating（充气）a foaming agent solution,to cement paste or cementmortar（灰浆）.The composition（合成物）,physical properties（性能）and uses of foam concrete were discussed in detail（详细的）by Valore,Short and Kinniburgh,Rudnai and Taylor.Although several investigations have been conducted on the properties of foam concrete, most of them deal with cement–sand mixes,neat cement paste with or without partial replacement（局部替换）using admixtures（掺合料）. Few studies report on the influence offiller type on the properties of foam concrete.By usingfly ash（粉煤灰）asfiller(fine aggregate细骨料) instead of sand,the high volume（体积）utilization（利用）offly ash becomes possible可能,thus providing a means of eco-nomic（经济）and safe disposal（处理）of this waste parison（比较）of strength of air-cured foam concrete made with cement-sand and cement–fly ash for masonry（砌体结构）by Durack and Weiqing show that for products of comparable density（比较密度）,mixes withfly ash asfine aggregate in place of sand gave relatively higher strength.Section2:Parameters(参数)investigated and mix compositions（组成成分）So much for the foam concrete,now I will move on to Parameters(参数)investigated and mix compositions.As the experimental programme(实验程序)was aimed at studying the effect of thefillers on the properties like density（密度）,flow behaviour（流动特性）,water absorption（吸水率）and strength of foam concrete,the following mixeswere investigated by keeping the basicfiller–cement ratio constant（恒定不变）at1:1by weight.The foam required for three densities（密度）of foam concrete viz.1000,1250,1500kg/m3were arrived at as per ASTMC796-97.In the cement–sand–fly ash mixes50%of the sand is replaced withfly ash and in the cement–fly ash mixes all the sand is replaced withfly ash.Section3:Effect of water–solids ratio（水砂比率）on design density That bring me to Effect of water–solids ratio（水砂比率）on design density.I think this part is the most important in my presentation,I will explain in detail.As the foam is added to the wet foam concrete mix,the consistency（稠度）of the wet mix is very important to get the design density.Fig.2(a)and(b)show the variation of density ratio（密度变化率）(measured fresh density divided（分离）by design density)with water–solids ratio for mixes with differentfiller type for each of the design densities,viz.,1000and1500kg/m3,respectively（分别地）.It is observed that at lower water–solids ratios,i.e.,at lower consistency,the density ratio is higher than unity（个体）.The mix is too stiff（严格地）to mix properly thus causing the bubbles（气泡）to break during mixing resulting in increased density.At higher water–solids ratios there is also an increase in density ratio as higher water contents make the slurry（泥浆）too thin to hold the bubbles resulting in segregation（分离）of the foam from the mix along with segregation of the mix itself thus causingan increase in measured density.Therefore,as shown in Fig.2(a)and(b), a density ratio of unity or nearly unity is achieved only at a particular consistency.This consistency requirement for the mix before adding foam to it can be expressed in terms of water–solids ratio.It is also observed that the water–solids ratio required to obtain a density ratio value of one,depends on thefiller type.Section4:ConclusionThe conclusions drawn from this study and summarized below are applicable（合适的）to the characteristics of the materials（材料特性）used and the range of parameters（参数范围）investigated:(i)the consistency of pre-formed foam concrete mixtures(defined as the water–solids ratio for achieving the target（目标）density)mainly depends on thefiller type,i.e.,relatively higher for mixes withfly ash asfiller compared to mixes with sand;(ii)theflow behaviour mainly depends on the foam volume and as the foam volume increases theflow decreases. For a given density,foam concrete withfly ash asfiller showed relatively（相当的）higherflow values;(iii)for a given density,an increase infly ash content of the mix results in increased strength.In comparison（比较）to cement–sand mixes,cement–fly ash mixes showed relatively higher water absorption（吸收）.That’s all.Thank you!Are there any questions?The picture on this slide isSo much for......,now I will move on to......This slide shows the calculation resultAs we know,the target user usually has taken a list of courses rather than a course,so we need to extent our probability calculation formulars.For example,suppose T={a,b},Pr[x﹁T]the probability x occurs without either an a or b preceding it;Pr[x﹁T]the probability x occurs without either an a or b following it.This probability can be calculated exactly. So how to calculate it?That bring me to Recommendation Algorithms.I think this part is the most important in my presentation,I will explain in detail.In conclusion,we proposed a novel precedence mining model,developedTo sum up,first,I introduced the motivation and the outline of work; second,I gave the definition of precedence mining model;third,I described some new recommendation algorithms using precedence information;forth,I showed our experimental results to compare the new algorithms with traditional ones.Finally,I made a conclusion of our work..That’s all.Thank you!Are there any questions?。

Good morning/afternoon/evening, and welcome to the 2023 International Conference on Sustainable Development and Global Challenges. It is a great pleasure to be here among such a distinguished group of experts, scholars, and practitioners who have gathered to discuss and find solutions to some of the most pressing issues facing our world today.My name is [Your Name], and I am honored to represent [YourOrganization/Institution] at this conference. Today, I would like to focus on the topic of "Sustainable Urbanization: A Key to Global Resilience and Inclusive Growth."As we all know, urbanization is a double-edged sword. On one hand, ithas been a major driver of economic growth and technological innovation. Cities are hubs of creativity and entrepreneurship, attracting people from all over the world in search of better opportunities. On the other hand, rapid urbanization has led to numerous challenges, including overcrowding, pollution, inequality, and climate change.Firstly, let us address the issue of overcrowding. The United Nations predicts that by 2050, two-thirds of the world's population will live in urban areas. This dramatic shift in population distribution will put immense pressure on existing infrastructure and public services. To mitigate this challenge, we need to prioritize smart urban planning.This involves designing cities that are adaptable, resilient, andcapable of accommodating diverse needs. We must invest in sustainable transportation systems, efficient public utilities, and green spaces to enhance the quality of life for all residents.Secondly, we cannot ignore the environmental impact of urbanization. The rapid growth of cities has been accompanied by an increase in greenhouse gas emissions and pollution levels. To combat this, we must embrace renewable energy sources and promote sustainable practices in urban development. Initiatives such as green roofs, urban agriculture, and the use of eco-friendly materials can significantly reduce our carbon footprint and improve air quality.Furthermore, we must tackle the issue of inequality that often arises in the context of urbanization. Cities can become places of stark contrasts,with wealthy neighborhoods coexisting alongside slums. To ensureinclusive growth, we need to implement policies that promote social equity and provide equal access to education, healthcare, and employment opportunities. This can be achieved through targeted investments in underprivileged areas and the development of affordable housing.Lastly, climate change is a pressing global challenge that requires urgent action. Urban areas are particularly vulnerable to the impacts of climate change, such as extreme weather events and rising sea levels. To build resilience against these threats, we must integrate climate change adaptation and mitigation strategies into our urban planning and development processes. This includes constructing infrastructure thatcan withstand extreme conditions and promoting community-basedadaptation measures.In conclusion, sustainable urbanization is crucial for achieving global resilience and inclusive growth. By addressing the challenges of overcrowding, environmental degradation, inequality, and climate change, we can create cities that are sustainable, livable, and equitable. It is through collaboration, innovation, and a shared commitment tosustainable practices that we can overcome these obstacles and create a better future for all.I would like to propose the following actions to be taken by governments, businesses, and civil society:1. Implement comprehensive urban planning policies that prioritize sustainability and inclusivity.2. Invest in renewable energy and green infrastructure to reduce the carbon footprint of cities.3. Promote social equity and provide equal access to essential services for all residents.4. Develop climate-resilient urban areas that can withstand the impacts of climate change.5. Foster international cooperation and knowledge sharing to advance sustainable urbanization worldwide.Thank you for your attention. I look forward to engaging in a lively discussion with all of you and exploring the ways in which we can work together to make our cities more sustainable and livable for future generations.Thank you.。

国际会议发言稿双语
Ladies and Gentlemen, Distinguished Delegates, Colleagues:Good morning/afternoon. It is a great honor and pleasure to stand before you today at this prestigious international conference. As we gather here from various corners of the globe, we are united by a common goal: to discuss and find solutions to the pressing challenges of sustainable development. In my speech today, I will focus on the current challenges, the opportunities that lie ahead, and the collective responsibility we all share in shaping a sustainable future.Current Challenges: A Call to ActionFirstly, let us acknowledge the current challenges that threaten our planet and its inhabitants. Climate change remains the most pressing issue of our time. The Intergovernmental Panel on Climate Change (IPCC) has issued stark warnings about the escalating consequences of global warming. Rising sea levels, extreme weather events, and the loss of biodiversity are just a few of the devastating impacts we are already witnessing.Moreover, inequality and poverty continue to be pervasive issues. Despite significant progress in reducing extreme poverty over the past few decades, millions of people still lack access to basic services such as clean water, sanitation, healthcare, and education. This gap not only hinders human development but also exacerbates social tensions and conflicts.The COVID-19 pandemic has further highlighted the interconnectedness of our world and the vulnerabilities of our global systems. It has exposed weaknesses in healthcare systems, supply chains, and social protection mechanisms. The economic impact of the pandemic has disproportionately affected the most vulnerable populations, deepening the divide between the rich and the poor.Opportunities for Sustainable DevelopmentDespite these challenges, there are numerous opportunities for sustainable development that we cannot afford to ignore. Innovation andtechnology have the potential to revolutionize our approach to environmental protection, social justice, and economic growth.Renewable energy sources, such as solar, wind, and hydroelectric power, are becoming increasingly cost-effective and efficient. The transition to a low-carbon economy is not only necessary to mitigate climate change but also presents a massive economic opportunity. The global renewable energy market is expected to grow exponentially in the coming years, creating jobs and stimulating economic growth.Innovation in agriculture and food systems can address both foodsecurity and environmental sustainability. Precision farming, vertical farming, and the development of climate-resilient crop varieties can enhance productivity while reducing the environmental footprint of agriculture.Moreover, digital technology has the potential to transform education, healthcare, and governance. E-learning platforms, telemedicine, and blockchain can improve access to quality services and promote transparency and accountability.Collective Responsibility and CollaborationThe realization of these opportunities requires collectiveresponsibility and collaboration. Governments, businesses, civil society organizations, and individuals must work together to create an enabling environment for sustainable development.Governments have a crucial role to play in setting ambitious targets and implementing policies that promote sustainable practices. This includes investing in renewable energy infrastructure, implementing progressive taxation systems, and ensuring that social protection measures are in place for the most vulnerable.Businesses must embrace sustainable practices and innovation, not only to comply with regulatory requirements but also to drive economic growth and enhance their competitive advantage. The concept of the circular economy, where resources are reused and recycled, offers a promising path forward.Civil society organizations and individuals can contribute by raising awareness, advocating for change, and participating in community-based initiatives. The power of collective action cannot be underestimated.ConclusionLadies and Gentlemen, the future of sustainable development lies in our hands. We are at a critical juncture where the decisions we make today will shape the world our children and grandchildren inherit. It is a future filled with challenges, but also with immense opportunities.Let us seize these opportunities by working together, fostering innovation, and promoting a culture of sustainability. Let us remember that we are all stakeholders in this journey and that our collective actions can and will make a difference.Thank you for your attention, and I look forward to engaging in a productive dialogue with you over the course of this conference.结束Title: The Future of Sustainable Development: Challenges and Opportunities女士们，先生们，尊敬的各位代表，同事们：上午/下午好。

国际会议主旨演讲稿范本尊敬的各位嘉宾、尊敬的各位代表，大家好！首先，我要感谢主办方邀请我来发表这次国际会议的主旨演讲。
本次会议的主题是关于可持续发展的，这是一个十分重要且紧迫的议题。
在我今天的演讲中，我将从几个方面来探讨可持续发展的重要性以及我们应该采取的行动。
首先，让我们来看看可持续发展的概念。
可持续发展是指满足当前需求的同时，不损害后代满足其需求的能力。
换句话说，我们要确保我们的行动不会对环境、经济和社会造成不可逆转的损害。
可持续发展不仅仅是一种理念，更是一种行动的指导原则。
那么，为什么可持续发展如此重要呢？首先，我们生活在一个资源有限的地球上。
随着全球人口的增长和经济的发展，资源的消耗速度越来越快。
如果我们不采取行动来保护和管理这些资源，我们将面临资源枯竭的风险。
其次，我们也面临着严重的环境问题，例如气候变化、水资源短缺和生物多样性丧失等。
这些问题不仅会对我们的生活造成直接的影响，还会对未来几代人的生活产生深远的影响。
那么，我们应该如何实现可持续发展呢？首先，我们需要加强政府和企业的合作。
政府应该制定和执行相关的法律和政策，鼓励企业采取可持续的经营方式。
同时，企业也应该自觉地履行社会责任，推动可持续发展。
其次，我们需要加强教育和宣传工作。
只有当人们了解可持续发展的重要性，并且知道如何采取行动时，才能真正实现可持续发展的目标。
此外，我们还需要加强国际合作。
可持续发展是一个全球性的问题，需要各国共同努力，分享经验和资源，共同解决。
在实现可持续发展的过程中，科技创新起着至关重要的作用。
科技创新可以帮助我们找到更加高效和环保的方式来生产和消费。
例如，可再生能源技术的发展可以减少对化石燃料的依赖，减少温室气体的排放。
另外，智能城市和智能交通系统的发展可以减少能源的浪费和环境污染。
因此，我们应该鼓励和支持科技创新，为可持续发展提供更多的解决方案。
最后，我想强调的是，可持续发展是一个长期的过程，需要我们每个人的参与和努力。
国际会议主题发言稿
国际会议主题发言稿尊敬的主持人、各位来宾：大家好！首先，我要感谢主办方给予我这次在国际会议上发表演讲的机会，我感到非常荣幸。
今天，我想和大家探讨的是关于国际合作与沟通的重要性。
当今世界，全球化的进一步发展使得各国之间的联系更加紧密，国际交流与合作已成为推动世界发展的重要动力。
首先，国际合作和沟通有助于各国共同应对共同面临的挑战。
我们生活在同一个地球上，面对的问题往往是共同的。
例如，气候变化、环境污染、贫困等问题无国界，需要各国共同合作才能找到解决方案。
通过国际会议和交流，各国可以分享经验、借鉴先进的做法，共同应对这些全球性挑战。
其次，国际合作和沟通有助于促进经济的繁荣与发展。
不同国家之间存在着各自的优势和特点，通过国际贸易和合作，各国可以互利共赢，实现资源的优化配置和互补发展。
国际间的交流与合作也推动了科技的创新和进步，促进了全球经济的发展。
此外，国际合作和沟通对于文化的交流和理解也起到了重要作用。
各国的文化和传统有着独特的魅力，通过国际间的交流，我们可以了解和欣赏不同文化，促进民族间的友谊和互相尊重。
同时，文化的交流也有助于促进和平与稳定，减少误解和误判，为各国和平共处提供了良好的基础。
然而，尽管国际合作与沟通的重要性被广泛认同，但我们也面临着一些挑战。
首先，语言和文化的差异是国际沟通的一大障碍。
不同国家使用不同的语言，拥有不同的文化背景，这往往给沟通和合作带来了困扰。
为了有效沟通和合作，我们需要不断加强语言学习和跨文化的交流。
其次，利益分歧也是国际合作面临的挑战之一。
各国的利益是复杂而多样的，有时会发生矛盾和冲突。
然而，我们需要超越狭隘的利益观念，深化对共同利益的认识，通过平等和互利的合作来解决分歧。
最后，国际合作和沟通的目标是实现共同发展与繁荣。
为了实现这一目标，我们需要促进多边主义和全球治理体系的建设，加强各国之间的交流与合作，共同应对全球性挑战。
让我们携起手来，共同为国际合作与沟通建设贡献我们的力量。

国际会议发言稿(精选多篇)第一篇：国际学术会议发言稿1. prologuethank you, mr. chairman, for your gracious introduction. i am honored to have the chance to address you on this special occasion. the topic of my paper is “transaction cost and farmers’choice of agricultural products selling”. the outline of my talk as follows. the first part i want to introduce the background of this research. the second part suggests a simple household choice model .the third part covers the data used in this research. and then, we introduce the empirical results. finally, a simple conclusion is given.2. introductionwell, let’s move on the first part of this topic .the motivation of this work like this. institutional economics posits that agents making decisions on different types of transactions do so in a costly way .for example , farmers deciding sell a particular crop to whom base their decisions not only on the price they expect to receive in each market choice but also on additional costs related to transacting in these markets.i want to use a picture to illustrate it. for example, given some market channels, farmers’choices can be regarded as equilibrium between the surplus and the additional costs that related to transacting .especially in developing countries, high-value crop producers fully participate in the market and the transaction cost has been the hard constraint to farmers. furthermore, farmers’market choices can be taken as a choice dilemma of transaction cost and production surplus. consequently, the scientific question of this research is how transaction cost affects planters’choices.3. methodologylet’s move to the theoretical model of our research. consider a household model in one rotation. in stage 1 , famer η needs to allocate the inp ut factors .this process can qbe set into a function like this q? ? q( p , w , z ? ) , qη means the output farmers decide qto produce .p implies the output price w implies input price and.z: ? is fixed input. once produce what and produce how many are decided, next question to be considered is how much products to be transacted in market. here we use three cc()cη means how functions to describe this question. the first equation, c ? ?p , z ?much agricultural products used by famers themselves. p implies the price thecagricultural product,z ?suggests the fluctuation of cη. the second equation q ? ? q ? ?c?, qη means the amount of agricultural products transacted inq?n?market. the third equationi ? q ?implies the amount exchanged in nth time.in stage 3, farmers will decide to sell the products to whom. chanel j’s market price isbdecided by an exogenesis price and farmers’negotiating power.pij?p*j?b(qi,zi)besides this, we use a matrix to show the net profit of chanel jx ik? ik, ? ?? ik ?and then farmers’choice can be expressed in a typical choice modelexp(xij?)pr(ji?j|xik)?1 exp(xij?)? k?1based on the choice model, another important concept is famers’channel choice .here, we set five types .they rank by the market barriers. accordingly, we set a group discrete number to express them. y: dependent variable y=5,means farmer choosebrokers. y=1, farmers sell products to consumers directly.4. data and estimation procedureshere, we illustrate the data distribution with this map. according to the agricultural regionalization from department of agriculture, the apple specialization areas in china contain two parts: bo sea area and loess plateau. bo sea area in red color, contains hebei, shandong and liaoning 3 provinces. and loess plateau in green color, contains shanxi, henan, shaanxi and gansu 4 provinces. firstly, we use pps method to get the first stage sampling unit 14 counties in 7 provinces. then use random sample method to get village and household. they are our sample distribution.5. empirical results6. conclusions第二篇：国际会议国际会议：20XX 2nd international conference on environment science and engineering(icese 20XX)post by：20XX-7-24 19:09:28 [只看该作者]20XX 2nd international conference on environment science and engineeringmay. 26, 20XX news! the icese 20XX papers are available in the vol.8 of ipcbee.(click)mar.16, 20XX news! the conference program of icese 20XX is available now.
