网络人肉搜索与侵犯个人隐私权问题研究

通过对一些有关于人肉搜索的典型案例分析的基础上，揭示了人肉搜索的运行机制。人肉搜索是一种特殊的信息搜索方式，同时也是一种新的信息生产方式。正确使用的话可以弥补机器搜索引擎的不足，但如果被滥用的话，则可能造成对个人隐私权的侵犯。     

Guest Editorial Production Planning and Control in other Industries

This paper provides an excursion into various scheduling problems arising in the manufacturing environment and possible approaches that can be taken to solve them. It reviews the research in production scheduling from the perspective of designing and operating a production system and examines the research strategies adopted to find the solution of the practical problems. This review is in the form of the paradigms that evolved during the twentieth century and shows the transition in theory and practice of each paradigm. It covers the fundamental frameworks of scheduling theory, outlining various approaches that can be taken to solve (optimally or approximately) such problems, and the difficulties arising in their practical use. Subsequently, an iterative scheduling process is suggested as an extension of existing paradigms to solve practical production scheduling problems and to bridge the gap between theory and practice in production scheduling and control.     

Conflicts of Interest in Academic Research: Policies,Processes, and Attitudes

Few studies have examined academic researchers' understandings of or attitudes toward conflict of interest policies even though these understandings and attitudes represent a crucial component of both compliance and educational efforts. This study reports the results of a large-scale, cross-sectional survey of research faculty at the nine campuses of the University of California regarding their understandings of and attitudes toward campus conflict of interest policies. We gathered information on their general assessments of investigators with financial ties to industry sponsors and reactions to the process of implementing conflict of interest policies at their respective campuses. We surveyed 1,971 faculty members from the nine-campus University of California system and had 779 responses (39% response rate). The sampled faculty were in the ten departments with the most number of financial disclosures at each campus. We utilized the WebSurveyor software to create a secure, online, 21-item survey. Our study reveals faculty with complex, sometimes contradictory, feelings about academic-industry relationships and highlights perceived gaps in policy and process. Most respondents were concerned about unlimited financial relationships, but a sizable number also viewed campus policies as irrelevant. Some expressed considerable anger over the process of policy implementation, rejecting the policies on the basis of professional and individual self-determination and moral integrity. Our study suggests the need for renewed efforts to encourage awareness of the relevance of conflict of interest policies for all faculty, new efforts to increase understanding of the situational nature of conflicts of interest, and a reexamination of the processes of policy implementation at the campus level.     

因子模型门槛效应的LM和Wald检验及其统计性质研究

门槛因子模型可以有效地刻画高维度时间序列的共变特征和区制转换行为,具有良好的可解释性和预测能力。针对因子载荷矩阵存在的门槛效应,本文提出了拉格朗日乘子和沃尔德检验方法,并给出了渐近分布,相关结果表明以上检验统计量具有良好的大样本性质和有限样本表现。在实证部分,以我国股市的行业指数作为研究对象,通过构建门槛因子模型来刻画我国股票市场波动的共变性特征和非对称效应。实证结果表明基于门槛因子模型可以很好地刻画中国股市行业收益率波动的共变特征和区制转换行为。     

论市场交换的供给与需求、成本与收入双重属性(上)

本文试图以一种崭新的非均衡的供给与需求、成本与收入双重属性的市场交换概念,重新阐释市场交换问题。两个人在竞争市场上相互交换的两种不同商品,既是自己的供给商品,即自己生产、拥有、卖出的商品,又是对方的需求商品,即对方用供给商品买回的满足自己需要的商品,两个交换商品具有供给与需求双重属性,这种属性说明用什么交换什么;供给商品生产和交换消耗的费用称谓供给成本,简称成本,用成本买回的需求商品称谓需求收入,简称收入,两个成本交换后变成了两个收入,成本与收入也有双重属性,这种属性说明两种交换商品用多少成本换回多少收入。市场交换就是用供给交换需求,用成本交换收入,追逐收入大于成本的利润,避免收入小于成本的亏损,这就是市场交换机制。     

上海市人口老龄化：现状、影响及对策思考

人口老龄化已成为当今世界各国经济发展过程面临的共同性话题,就上海而言．未来上海市人口老龄化带来的影响已逐渐凸显,人口老龄化带来的养老金匮乏,劳动力不足以及社区为老服务发展滞后的矛盾已开始成为制约上海市经济发展的瓶颈,老龄化带来的影响将在未来很长一段时间内长期存在．缓解人口老龄化带来的影响以及寻求可行性办法解决老龄化人口的赡养问题已成为政府和社会必须要解决的问题。     

Bayesian inference for the parameters of Weibull distribution under progressive Type-I interval censored data with beta-binomial removals

This article considers the problem of estimating the parameters of Weibull distribution under progressive Type-I interval censoring scheme with beta-binomial removals. Classical as well as the Bayesian procedures for the estimation of unknown model parameters have been developed. The Bayes estimators are obtained under SELF and GELF using MCMC technique. The performance of the estimators, has been discussed in terms of their MSEs. Further, expression for the expected number of total failures has been obtained. A real dataset of the survival times for patients with plasma cell myeloma is used to illustrate the suitability of the proposed methodology.

家庭结构对老年人代际支持的影响研究

本文利用中国老年健康影响因素跟踪调查（CLHLS）项目2008年的数据,分析了家庭结构的变迁（表现为居住安排与子女数量两方面）对老年人所获得的来自子女的代际支持的影响。研究结论显示,是否与子女同住会影响老年人获得的经济支持、情感支持与照料支持,而子女数量对代际支持的获得有正向作用。     

网上考古的新发现——关于《碣石调·幽兰第五》的原本问题

《碣石调·幽兰第五》的原本问题为笔者同吴文光、戴微争鸣多年而未获结论的难题.最近,笔者运用http//www.emuseum.ip/cqi?SvoID=3&ID=wcq7&subid=s 000网站,发现了东京国立博物馆所藏《幽兰》卷纸本的原件,是为东京本之二.这次网上考古的发现证实了东京国立博物馆的确有两份《碣石调·幽兰第五》即东京本之一和东京本之二,后者为原本.本文探讨《幽兰》版本列表、对日本方面迟迟不提供原本之讨论.黎氏刊本与原本之比较等三方面问题.
