Prediction intervals for future Weibull residual data

In reliability theory, risk analysis, renewal processes and actuarial studies, the residual lifetimes data play an important essential role in studying the conditional tail of the lifetime data. In this paper, based on some observed ordered residual Weibull data, we introduce different prediction methods for obtaining prediction intervals (PIs) of future residual lifetimes including likelihood, Wald, moments, parametric bootstrap, and highest conditional methods. Monte Carlo simulations are performed to compare the performances of the so obtained PIs and one data analysis is performed for illustration purposes.     

That's My Art: A Case Study on Children's Views of Cultural Policy

How do children experience a participatory TV cultural policy project and, related to that, which views do they share on cultural policy matters? These questions guided a case study on a TV show aired on the Flemish children's public service channel, which staged children as cultural experts. Although the programme was presented as a participatory project, we found that the children's views were minimally involved in the production process. The children also expressed concerns about how (their) art and cultural practices were represented. Yet, from a cultural policy perspective, the children accepted adults’ authority in art and cultural matters.     

A Quantitative Estimate of the Dominant Position of Public Ownership in China and Trends in Its Development

以不同生产资料所有制的经营性资产价值量作为衡量主次地位的边界标准，估算第一产业公有制与非公有制的资产规模及其比重变化，并在前人估算的基础上，延伸估算第二和第三产业两种所有制的资产规模及其比重变化。结果发现：截至2012年，中国三次产业经营性总资产约为487．53万亿元，其中公有制经济的资产规模是258．39万亿元，占53％；第二、三产业非公有制经济占增加值和就业规模的比重分别为67．59％和75．20％。这表明，公有制资产仍占主体，非公有制经济贡献占优，中国社会主义基本经济制度充满活力，从而为我国社会主义初级阶段的所有制改革和坚持“两个毫不动摇”的政策提供了理论依据。     

On a system of nonhomogeneous components sharing a common frailty

The components of a reliability system subjected to a common random environment usually have dependent lifetimes. This paper studies the stochastic properties of such a system with lifetimes of the components following multivariate frailty models and multivariate mixed proportional reversed hazard rate (PRHR) models, respectively. Through doing stochastic comparison, we devote to throwing a new light on how the random environment affects the number of working components of a reliability system and on assessing the performance of a k-out-of-n system.     

Relations Between Alphabetized Name Order and Nomination Counts in Peer Nomination Measures

Peer nominations, a central method for measuring peer relationships in developmental research, typically involve asking children or adolescents to choose peers who fit various criteria from an alphabetized roster of classmates or grade‐mates. Although such measures have been used for decades, very little research has investigated the effects of alphabetical name order on the number of nominations received by peers. This study collected peer nominations for 20 items among 607 eighth grade participants in two schools. Regression analyses showed that earlier name order significantly predicted higher nomination counts for eight of the items, and explained over 5 percent of the variance in four affective variables (friendship, acceptance, acquaintanceship, and received liking). Across variables, name order effects were negatively correlated with internal reliability of nominations, implying that order effects may be related to the consensus of the peer group. Name order also had a minimal effect on inter‐correlations among a subset of variables. Implications and concrete recommendations for controlling and reducing name order effects in future research are discussed.     

关于对贞卜辞同字异形判定的三个问题

对贞卜辞是甲骨文中有特色的文例形式，我们从对贞卜辞的判定、同字异形现象的判定以及两条卜辞刻写先后顺序的判定三个方面来细致研究对贞卜辞，进而为下一步的研究打下基础。     

Hazard rate ordering of the second-order statistics from multiple-outlier PHR samples

In this paper, we compare the hazard rate functions of the second-order statistics arising from two sets of independent multiple-outlier proportional hazard rates (PHR) samples. It is proved that the submajorization order between the sample size vectors together with the supermajorization order between the hazard rate vectors imply the hazard rate ordering between the corresponding second-order statistics from multiple-outlier PHR random variables. The results established here provide theoretical guidance both for the winner's price for the bid in the second-price reverse auction in auction theory and fail-safe system design in reliability. Some numerical examples are also provided for illustration.     

公益诉讼费用分担方式的构建

公益诉讼费用是公益诉讼必然面临的问题,其合理与否极大地关系着人们享受法律保障的程度。但公益诉讼往往诉讼成本高,导致公益诉讼难以取得理想的预期效果,而现行的诉讼费用分担方式并不能完全适应公益诉讼的发展需要。因此,应从被告方分担、受益者分担、国家分担三方面入手,通过设立公益诉讼奖励基金以及费用移转支付的方式,建立起一个与公益诉讼理念相契合的公益诉讼费用分担方式。     

试论我国新闻舆论监督现状及其前景

我国新闻舆论监督在近年来取得了良好的成效,尤其是监督方式方面得到了较快发展.但是不足的一面比较明显：监督缺乏相对的独立性,理论研究不足,总体水平不高.我国新闻舆论监督的发展方向是：应该加大对政府部门和官员的监督力度和加大本区域监督和跨区域监督的力度,制度建设和法律建设应迈出更快步伐.
