Exact sample size determination in a weibull test plan when there is time censoring

Engineers who conduct reliability tests need to choose the sample size when designing a test plan. The model parameters and quantiles are the typical quantities of interest. The large-sample procedure relies on the property that the distribution of the t -like quantities is close to the standard normal in large samples. In this paper, we use a new procedure based on both simulation and asymptotic theory to determine the sample size for a test plan. Unlike the complete data case, the t -like quantities are not pivotal quantities in general when data are time censored. However we show that the distribution of the t -like quantities only depend on the expected proportion failing and obtain the distributions by simulation for both complete and time censoring case when data follow Weibull distribution. We find that the large-sample procedure usually underestimates the sample size even when it is said to be 200 or more. The sample size given by the proposed procedure insures the requested nominal accuracy and confidence of the estimation when the test plan results in complete or time censored data. Some useful figures displaying the required sample size for the new procedure are also presented.

论章学诚以《随园诗话》为中心的袁枚批评

章学诚对袁枚《随园诗话》有专论文章,态度激烈,语言犀利,研究专家多斥章学诚为卫道。本文对章批《随园诗话》进行了简略的考察,认为章学诚以《随园诗话》为中心的对袁枚的批评可谓实事求是、有的放矢,既不是所谓简单的"卫道"也不是空言无依,网人入罪,而是袁枚在《随园诗话》及其著作和个人行为的具体揭示,也是章学诚文学观念的具体展现和"文不空言"的有为之言。     

论水平扭剪应力场对大裂缝系统的控制

本文根据地质力学和岩体结构力学原理，探讨水平扭剪应力场在大裂缝系统形成、转化和分布中的重要控制作用及其物理模型．文中认为，大裂缝系统是较大的直压型裂缝网络与扭剪型裂缝网络叠加的产物，主要分布在较强的水平扭剪应力和术平直压应力复合作用的区块；水平扭剪应力场是改造和控制大裂缝网络结构异向性的最重要因素。这为研究和勘探较大的隐伏裂缝系统，提供了新的成藏模式和理论依据。     

Tilting at windmills: a cynical assemblage of the crises of knowledge

The essay offers one piece of a larger conjunctural analysis, in an effort to contribute to a better story of the contemporary organic crisis. It considers three elements of the complexity of the ‘crises’ of knowledge: First, it explores the increasingly felt social perception that knowledge (and the forms of authority that accompany it) has become less determined and determining, less identifiable, less effective, more troubled. It argues that one must think about these developments historically and contextually, rather than going along with the panic that has surrounded their increasing visibility in recent political events. Second, it considers some of the attacks on the university as well as some of the recent changes in the political economy and institutional forms of the academy. Finally, it argues that academics have failed to examine their own contributions to the crises of knowledge, failed to consider the ways their own cultures and practices can be located within rather than against the crises of knowledge.     

Multiple comparisons of exponential location parameters with a control based on doubly censored sample under heteroscedasticity

In this article, a one-sample procedure for multiple comparisons of exponential location parameters with a control under heteroscedasticity is proposed. The observations are obtained by doubly censored samples. A one-sided and two-sided confidence intervals are used to perform such multiple comparisons. Statistical tables of critical values and an example of comparing four drugs in treating leukemia are provided.     

充分发挥主体性：深入践行科学发展观的着力点

主体性是人的本质属性，其根本内涵表现为自主性、能动性和创造性。人的主体性是践行科学发展观的内源动力。主体性的充分发挥有助于把握和领会科学发展观的内涵，化解践行科学发展观过程中的矛盾、困境及掌控科学发展观赋予的科学发展方向。高扬人的主体精神，立足人的主体地位和充分发挥人的主体作用，是深入践行科学发展观人本核心、发展要务的关键所在，故此，充分发挥主体性理应成为践行科学发展观的着力点。     

Sociology and the European Court of Human Rights

This article offers a sociological analysis of the jurisprudence of the European Court of Human Rights (ECtHR). Adopting a sociological jurisprudence approach, the article aims to demonstrate the unique and valuable contribution that sociology can make to understanding key aspects of international human rights law. Whilst the article seeks to develop an agenda for critical sociological research on human rights law, it also aims to persuade those charged with the supervision of human rights of the value of sociological analysis. To achieve this, the article focuses on three separate but inter‐related aspects of ECtHR jurisprudence: first, it considers the ECtHR's approach to consensus in its adjudication of human rights complaints; second, it examines the social control implications of the ECtHR's decisions and judgments; and third, it assesses how conceptualizations of social identity are often foundational to the ECtHR's reasoning.     

“重陆轻海”与“通洋裕国”之海洋观刍议

明清两朝正处于世界性海洋历史发展的"千古变局"时代,但统治者沿袭传统模式,在立国思想上"重农抑商"、"重陆轻海",在国防战略上以"禁海"代替海防,禁海迁界、"守土防御",反映其海洋观念的淡薄;而东南沿海地方官员,尤其郑成功"通洋裕国"思想的提出和实践,显露出"以商立国",向海洋空间发展的意涵;传统时代"重陆轻海"与"通洋裕国"所反映的海洋观念,对国家民族发展的影响在某种程度上可以忽略不计,但大航海时代,海洋作为人类的第二生存空间影响到世界历史走向和发展格局时,"重陆轻海"观念所带来的深层影响会因此而改变国家和民族的命运。
