高校科技创新研究平台的构建与实现探析

针对高校目前研究人员之间的科技资源和成果相互封锁、开展多学科交叉研究面临多方面的困难、政策不完善、难以组建创新团队,以及研究群体组织模式落后等问题,探讨构建科技创新研究平台的意义并提出平台构建形式,以改变科研小而分散的模式,整合科技队伍,促进学科的交叉、融合与资源的共享。     

公司价值形成的反身性机制与中国上市公司的实证研究

该研究把人的非完全理性和市场非有效对公司经理人投融资行为的影响融入公司价值的形成过程,构建了公司的价值体系,分析了公司价值形成的反身性机制。用公司价值预期与公司真实的价值创造之间的关系来建立实证模型,检验公司市场价值与内在价值之间的相关性。以中国上市公司为样本进行了实证研究,发现公司价值创造效率与市场的价值预期之间存在显著的相关关系:首先,市场对上市公司的价值预期存在偏离,表现为高估低内在价值的公司和低估高内在价值的公司;其次,这种市场预期的偏差对上市公司的价值创造具有显著的影响,表现为阻碍公司价值的创造。实证结果证明了公司价值形成反身机制的存在性。     

《二十四孝图》新解

《二十四孝图》是中国封建历史上孝子的典范故事,作为华夏民族的优良传统体现出中国独特的人文精神,我们需要为此发扬光大。但需要用马克思历史唯物主义的观点来重新审视这种历史沉淀物,使其更好的体现民族品格。     

ONE LUMP OR TWO: UNITARY VERSUS BIFURCATED MEASURES OF INJURY AT THE USITC

The most popular methodology used by the US International Trade Commission (USITC) commissioners to determine whether dumped and/or subsidized imports injure competing domestic industries has been rejected by reviewing bodies because it does not distinguish injury caused by unfairly traded imports from other demand or supply changes. We estimate injury to the domestic industry due to changes in unfairly traded import price and to other causes for 44 USITC dumping and/or subsidy investigations. Change in unfairly traded import price was typically not the most important cause of injury to the domestic industry. (JEL F13 )     

Low dose risk estimation via simultaneous statistical inferences

Summary.  The paper develops and studies simultaneous confidence bounds that are useful for making low dose inferences in quantitative risk analysis. Application is intended for risk assessment studies where human, animal or ecological data are used to set safe low dose levels of a toxic agent, but where study information is limited to high dose levels of the agent. Methods are derived for estimating simultaneous, one-sided, upper confidence limits on risk for end points measured on a continuous scale. From the simultaneous confidence bounds, lower confidence limits on the dose that is associated with a particular risk (often referred to as a bench-mark dose ) are calculated. An important feature of the simultaneous construction is that any inferences that are based on inverting the simultaneous confidence bounds apply automatically to inverse bounds on the bench-mark dose.     

文学翻译：特殊的艺术再创作

通过对艺术创作过程的分析,论证文学翻译为一门特殊的艺术再创作。无论是创作冲动、艺术构思,还是艺术表达,文学翻译与艺术创作都具备同一性。但是两者并非完全相同,文学翻译受到原作等各方面因素的限制。通过对这一问题的论述,提倡创造性翻译,以实现译者的自身价值。     

全要素生产率变动的分解——基于Malmquist生产力指数的实证分析

一、引言关于全要素生产率(TFP)的讨论,是当今经济学界的热门话题。对它的研究已经成为应用经济学领域中十分活跃的分支。全要素生产率(TFP)的最初研究开始于丁伯根(1942)和索洛(1985)在新古典的框架下研究“索洛余值”对增长的贡献。后来大量关于全要素生产率的研究中,Fare(1985,1989,1994)以及coelli(1996)发展了全要素生产率变动的测量方法,并进行了卓有成效的经验分析。目前对全国特别是各省区市全要素生产率的计算,已经有许多研究成果发表,这方面的代表性文献是支道隆(1997)、Fleisher and Chen(1997)、李京文(1998)、张军和施少华…     

International guidelines and the inclusion of disabled people. The Ugandan story

Uganda has made much progress towards including disabled people in its mainstream development, particularly in the political agenda. The exact process by which this has been achieved and the relationship between this and international guidelines and legislation are not known. This study undertakes to examine this from two specific perspectives: (1) How do international documents relevant to disabled people relate to national legislation in Uganda? (2) What can this comparison, together with the perceptions of stakeholders, tell us about how the legislation and services could improve? International legislation and Ugandan legislation is reviewed and compared. Data from 5 semi‐structured key informant interviews and 6 focus group discussions involving a total of 38 people are collected and analysed. The themes arising from the data are related to the documents, legislation, policies and other relevant literature. The results examine the barriers to service provision; the role of change; the importance of representation; policy and legislation issues; and the effects of devolution. Five specific findings relate to how legislation and services can improve: more resources to increase access for disabled people; strong leadership and collaboration between Disabled People’s Organisations (DPOs) funding bodies and governments; awareness raising and training; representation from all impairment groups; and raising the profile of disabled people through further legislation.     

关于构建和谐的社会利益协调机制的思考

日益加剧的社会利益分化和利益矛盾,内在地要求我们必须切实构建起和谐的社会利益协调机制。构建和谐的社会利益协调机制,要承认和尊重社会物质利益的差别,要坚持以公正的原则处理各种利益关系。当前,必须要改变过去协调利益矛盾政策滞后的状况,颁布切实有效的、和谐的协调利益矛盾的政策;要构建和谐的利益表达与实现机制;要实现社会利益调节法治化;要建立和谐的社会利益导向机制。
