"V有"式"V""有"之关系及相关问题

从“V有”句式的研究入手,重点对“V有”中“V”的特征、“V”和“有”之间的关系进行了分析,给出了“V”的测试格式。同时,认为“V有”是一种表示结果态的动态关系,其中的“有”丧失了独立的表义功能,变成了一个附加成分。     

关于设立大学生创新基金的思考

大学生创新基金的设立,是培养学生的创新意识和科研实践能力的一种新思路。大学生创新基金在培养创新性人才中起着构建平台、提供动力、营造空间、奠定基础的重要作用。建议各高校采取鼓励大学生共同参与、独立申报,制定本科导师制,自选课题、自主设计实验方案,组织学生参加创新大赛,拓宽创新渠道等具体措施,以推动创新基金的健康发展。     

在传统、现代性与后现代性之间——信息时代中国现代化难题的深层根源

传统、现代性与后现代性三重因素的矛盾和冲突是信息时代中国现代化难题的深层根源,而经济发展与环境资源、中国传统文化与西方文化、工业社会与后工业社会之间的矛盾只不过是这一深层根源在不同层面上的外在表现形式     

差异政治与协商民主

兴起于20世纪80年代的差异政治理论对普遍主义的政治模式提出了质疑,强调差异性、多元文化在政治生活中应受到平等尊重和承认权利.20世纪90年代兴起的协商民主理论,其前提在于承认并解决多元文化社会的现实,通过公共协商解决自由主义民主理论缺陷.然而,协商民主与差异政治两者表面的亲密关系却无法掩饰其实质性的分歧.二者背后隐含着现代民主政治的内在悖论--是以无差别的个人主义抑或以有差别的社群主义为原则?该问题是协商民主理论领域内最重要的议题之一.     

Control‐based imputation for sensitivity analyses in informative censoring for recurrent event data

In clinical trials, missing data commonly arise through nonadherence to the randomized treatment or to study procedure. For trials in which recurrent event endpoints are of interests, conventional analyses using the proportional intensity model or the count model assume that the data are missing at random, which cannot be tested using the observed data alone. Thus, sensitivity analyses are recommended. We implement the control‐based multiple imputation as sensitivity analyses for the recurrent event data. We model the recurrent event using a piecewise exponential proportional intensity model with frailty and sample the parameters from the posterior distribution. We impute the number of events after dropped out and correct the variance estimation using a bootstrap procedure. We apply the method to an application of sitagliptin study.     

Impacts of the Triple Global Crisis on Growth and Poverty: The Case of Yemen

Yemen is an oil‐exporting and food‐importing country with the highest levels of poverty in the Middle East and North Africa. The impacts of the triple crisis are likely to further complicate pre‐existing conditions of conflict, oil depletion and governance failure. Using a dynamic CGE model, this article finds that oil‐driven growth in 2008 dominated the negative growth impacts of the food crisis, but that growth was not pro‐poor. The financial crisis of 2009 slowed growth sharply and raised the poverty rate to 42.8%, up from 34.8% in 2005/6. Poverty continues to be higher in rural areas, where almost half the population live in poverty.     

微翅管几何参数对混合工质流动沸腾特性的影响

对非共沸混合工质R32／R134a在水平微翅管内的流动沸腾特性进行了实验研究，获得了微翅管的翅高和翅数对换热性能的影响，并综合比较了3根微翅管的换热性能。同时，将微翅管与光管性能进行了比较。结果表明，在相同工况下，翅高为0．2mm、翅数为60的换热性能最好；微翅管的换热性能明显优于光管。     

坚持、运用和发展邓小平教育思想

邓小平教育思想的基本特征是战略性和全局性,邓小平充分论述了教育在国家现代化建设中的战略地位,江泽民对此做出了具有时代意义的新发展。我们要在邓小平教育思想的指引下,在江泽民对邓小平教育思想发展的基础上,进一步形成面对教育新情况、新问题所应当具备的现代教育理念,善于在教育实践中以改革的精神做出新的发展、新的创造。     

浅谈个人所得税存在的问题

现行的个人所得税制至少存在两个问题:一是个人取得年终一次性奖金的计税新政策“漏”出负效应区;二是代扣代缴个人所得税返还手续费使用管理有漏洞,应尽快采取相应的对策,以实现个人所得税管理的科学、规范和高效。     

Demand Constraints on Agricultural Growth in East and Southern Africa: A General Equilibrium Analysis

This article analyses demand constraints on agricultural growth in seven countries of East and Southern Africa using an applied general equilibrium framework. It finds that both traditional and non‐traditional export crops have limited potential to raise incomes because of demand constraints (for traditional exports) or a relatively small base (for non‐traditional exports). The best prospects for agriculture‐led growth remain in the food sector, where domestic demand represents a large and growing market. Improvements in market efficiency and simultaneous growth in the livestock sectors can help spur demand further and avert falls in prices. Achieving rapid gains in farm incomes, however, also requires investment in rural infrastructure to reduce marketing costs, and demand‐ enhancing growth in the non‐agricultural sector to spur demand.
