建设维护生命尊严的光辉世纪

现今的世界上,有许多人由于内战、贫困与饥饿、环境破坏等威胁,迫使他们的生命及尊严处于危险状态,也有大批人仍然饱受着人权侵害、种族歧视的痛苦。为和平、人权、人道的奋斗,绝不是低层爬到高山的顶峰就可以达到终点那样。重要的是要创建一股一代接一代、谁也阻挡不了的滔滔洪流,并日积月累地把它发展和扩大。这就是我们为了建设一个和平未来的不断挑战。     

“网络杜甫”:当代文化的一种美学思考

":网络杜甫"事件为我们观察当代文化提供了一个有益窗口。涂鸦的作者不同,反映出来的动机和利益也不同。商家和媒体利用此次事件实现了自身利益,但公众在其中除去"娱乐"自身之外,一无所获。此次事件并没有从根本上改变杜甫本人,而仅仅是一次当代的文化消费。公众娱乐和商家利益构成了整个事件的核心,因此在这种文化消费中,我们根本无法建立起精神、道德等要素。     

Judgmental overconfidence: Three measures, one bias?

Overconfidence is used to explain various instances of detrimental decision making. In behavioral economic and finance models, it is usually captured by misperceiving the reliability of signals and results in overweighting private information. Empirical tests of these models often fail to find evidence for the predicted effects of overconfidence. These studies assume, however, that a specific type of overconfidence, i.e. “miscalibration,” captures the underlying trait. We challenge this assumption and borrow the psychological methodology of single-cue probability learning to obtain a direct measure for misperceiving signal reliability. Our findings indicate that the perception of signal precision and measures of miscalibration are unrelated. We thus conclude that in order to test the theoretical predictions of the overconfidence literature in economics and finance, one cannot rely on the well-established miscalibration bias.     

Behrens-Fisher问题的正态逼近

 本文提出用基于得分检验的正态逼近方法来解决Behrens-Fisher问题，即比较方差比未知时两正态总体的均值。模拟结果显示：在所有的研究情况下，我们的方法都能很好地控制第一类错误，检验功效也不差；而最常用的Welch近似t检验在样本量不等时大多数情况都不能控制第一类错误。     

商标保护的行政视角分析

商标是企业的无形资产，是企业竞争力的主要体现，是企业发展的动力源。现代企业都非常重视对商标的保护，但是仅凭企业一己之力很难有效的保护商标专用权。因此，政府必须对商标提供有效的行政保护，通过提高商标执法人员素质、增强社会商标意识、实现行政方式的非权力化转换、建立商标预警机制和商标行政执法区域协作机制等方式进一步完善商标行政保护体系．增强保护能力。     

国际收支贸易调项 对中国贸易平衡的影响程度

 本文首先介绍新修订的国际收支表涉及贸易项目的调整要点，提出应重视加工贸易从货物转移到服务项下核算引起的对中国贸易平衡的影响。接着以主要篇幅对此进行测算和分析，得出影响虽然不小，但不会颠覆货物贸易平衡格局的结论。最后提出关于服务贸易理论和统计制度的四点思考。     

农民问题：中国粮食安全的根本问题?

粮食安全是国家安全的重要组成部分，是影响我国经济社会发展大局的重大战略问题。农民是实现粮食安全的经济主体，“谁来种粮”和“如何种粮”的问题的核心是农民问题，农民问题是影响粮食安全战略的根本问题，关乎国民经济全局、粮食生产稳定和农村社会和谐稳定。重视、研究和解决农民问题，是一个贯穿于我国整个改革开放和社会主义现代化进程中的时代性课题。土地问题、收入问题、权力问题、发展问题和职业培育问题是新时期正确认识农民问题的五个价值维度；以法的形式还地权于农民、千方百计增加农民收入、构建全方位的农民权利体系、全面提升农民发展能力和加快培育新型职业农民，是解决农民问题的根本举措。     

Perceived Risks of Conventional and Organic Produce: Pesticides, Pathogens, and Natural Toxins

Public risk perceptions and demand for safer food are important factors shaping agricultural production practices in the United States. Despite documented food safety concerns, little attempt has been made to elicit consumers' subjective risk judgments for a range of food safety hazards or to identify factors most predictive of perceived food safety risks. In this study, over 700 conventional and organic fresh produce buyers in the Boston area were surveyed for their perceived food safety risks. Survey results showed that consumers perceived relatively high risks associated with the consumption and production of conventionally grown produce compared with other public health hazards. For example, conventional and organic food buyers estimated the median annual fatality rate due to pesticide residues on conventionally grown food to be about 50 per million and 200 per million, respectively, which is similar in magnitude to the annual mortality risk from motor vehicle accidents in the United States. Over 90% of survey respondents also perceived a reduction in pesticide residue risk associated with substituting organically grown produce for conventionally grown produce, and nearly 50% perceived a risk reduction due to natural toxins and microbial pathogens. Multiple regression analyses indicate that only a few factors are consistently predictive of higher risk perceptions, including feelings of distrust toward regulatory agencies and the safety of the food supply. A variety of factors were found to be significant predictors of specific categories of food hazards, suggesting that consumers may view food safety risks as dissimilar from one another. Based on study findings, it is recommended that future agricultural policies and risk communication efforts utilize a comparative risk approach that targets a range of food safety hazards.     

Information Technology Risks as Seen by the Public

Risks related to information technology (IT) are becoming a focus of concern in current risk debates. The use of IT is rapidly spreading in the population, as is access to computers in general. The present article reviews the literature on IT use (especially electronic mail and various Internet applications) and the related risks. In addition, the results from a survey about IT use and risk perception, given to a random sample of the Swedish population, are reported. In general, participants were quite positive to IT and were, to some extent, aware of the related risks. However, risks of IT were mostly seen as pertinent to other people, a finding in contrast with other results on perceived technology hazards. The attitude toward the use of IT was strongly related to general attitude toward computers, and less clearly to risk perception. Only a small percentage of the respondents reported having had negative experiences with IT hazards such as Internet addiction, depression, and social isolation. When extrapolated to the general population, however, these small percentages amount to large groups in the population that have been negatively affected by IT use.     

在现实与心灵的二重空间鸣唱-九叶诗派的本体世界特征

九叶诗派的诗歌本体是一种提纯与升华了的经验,一种心灵与外物对话的情感哲学;它以客观化的抒情方式传达精神信息,求得与主体世界的呼应平衡,表现了现实与理想错位情境下的时代焦灼感、阵痛感,具体凝结为爱、批判、希望三个主题意向;以诗的方式把握世界,切入人生,是九叶诗派对中国新诗最独特的贡献.
