Covariate Order Tests for Covariate Effect

A new approach for constructing tests for association between a random right censored life time variable and a covariate is proposed. The basic idea is to first arrange the observations in increasing order of the covariate and then base the test on a certain point process defined by the observation times. Tests constructed by this approach are robust against outliers in the covariate values or misspecification of the covariate scale since they only use the ordering of the covariate. Of particular interest is a test based on the Anderson-Darling statistic. This test has good power properties both against monotonic and nonmonotonic dependencies between the covariate and the life time variable.     

The role of litigation in human research accountability

This essay examines and analyzes the recent and dramatic series of personal injury lawsuits instituted against those individuals and institutions that conduct and monitor human research. It discusses the social engineering functions of tort litigation, outlines the legal elements and viability of lawsuits against those who conduct and monitor human research, and evaluates and predicts what role tort litigation will play in fulfilling the goals of accountability in the context of human research and human research regulation. In general, tort law engenders two forms of accountability: retrospective and prospective. Retrospective accountability is backward looking, focusing on harms that have already occurred, their culprits, and the reimbursement of individuals for their injuries. Prospective accountability is forward looking in that it encourages actors and institutions to fulfill responsibilities toward individuals in order that harm does not occur, or at least that the risk of harm is decreased. This article argues that research litigation is not, and will probably never become, an effective means of ensuring retrospective accountability in regard to research injuries and ethical violations. Paradoxically though, the current wave of research litigation may serve an important and even key role in encouraging and ensuring prospective accountability.     

现代新儒家对五四新文化运动的省察梳要

五四新文化运动已过去八十余年了,检讨"五四"成为中国文化建设的重要内容。现代新儒家站在民族文化本位的立场上,对五四新文化运动进行了认真的梳理。一方面,他们对"五四"思想启蒙给予了积极的评价,认为新文化运动有功于儒家思想的新开展;另一方面,他们对"新青年"学者盲从西方的激烈反传统态度和唯科学主义思潮表示强烈的不满,具有否定"五四"的倾向。他们在反省"五四"的基础上,提出了重建中国文化的方案,充满着哲学的睿智,是一份宝贵的精神遗产。     

环境与贸易的可持续发展研究

贸易影响国民经济发展 ,国民经济又影响生态环境 ,环境与贸易是联系非常密切的两个领域。贸易使环境问题极端化 ,表现为环境问题国际化和局地化两个方面。环境问题对贸易影响主要是通过环保措施影响产品竞争力来实现。单独在各自领域寻找解决问题的措施 ,对可持续发展不利 ,也是不现实的。必须用可持续发展的生态经济综合观点考察环境与贸易的关系。基本原则一是向市场发出“新的稀缺信号”,促进环境成本内部化 ,具体执行中 ,政府的调整和监督作用应予以加强。二是发展和加强国际合作 ,促进环境保护和自由贸易的结合。三是加强立法 ,制定合理的环境与贸易国际法则     

关于"生产力"问题的几点思考

人类社会已进入知识经济新时代,亦应赋予"生产力"新的定义,即"所谓生产力,即社会生产力,是人们认识自然、改造自然,合理利用自然资源以谋求人类自身生存和全面发展的能力.它包括两个基本方面一是人类社会生产物质财富(或物质资料)的能力;二是人类社会生产劳动力的能力."它表示的是人们在生产过程中对自然界、社会的关系,而不仅仅是人们在生产过程中"对自然界的关系".同时,作者明确指出,"管理"也是一种"劳动","管理者"也是"劳动者";管理既是形成生产力的必要条件,又是创造生产力的源泉.应当重新认识管理与生产力之间的相互关系.

Investigating the impact of violations of the “left and top means first” heuristic on response behavior and data quality

ABSTRACT

Web surveys are an established data collection mode that use written language to provide information. The written language is accompanied by visual elements, such as presentation formats and shapes. However, research has shown that visual elements influence response behavior because respondents sometimes use interpretive heuristics to make sense of the visual elements. One such heuristic is the ‘left and top means first’ (LTMF) heuristic, which suggests that respondents tend to believe that a response scale consistently runs from left to right or from top to bottom. We conducted a web survey experiment to investigate how violations of the LTMF heuristic affect response behavior and data quality. For this purpose, a random half of respondents received response options that followed a consistent order and the other half received response options that followed an inconsistent order. The results reveal significantly different response distributions between the two groups. We also found that inconsistently ordered response options significantly increase response times and decrease data quality in terms of criterion validity. We, therefore, recommend using options that follow the design strategies of the LTMF heuristic.     

对联之对偶英译初探——从望城黑糜峰长联的英译谈对联英译的一些问题

对联是中华民族独有的文化瑰宝，但人们一直以为原对句不能译作外语对偶句，以致不懂汉语的人至今不能欣赏。通过对望城黑麋峰长联的英译探索证明，只要原对句语法结构相同，翻译成对偶句是完全可能的。对联能英译成对偶句，译成其他语言的对偶句也应当可能。对联这个问题可以解决，诗词曲的对仗句也应当可以解决。通过将望城黑麋峰长联英译成对偶句的三个步骤，以及在英译过程中得到的九个方面的认识作了初步的总结，希望有更多的人参与进来，共同努力，把我国的对联乃至诗词曲逐步介绍给其他民族的读者。
