Noninformative priors for linear combinations of normal means with unequal variances

For normal populations with unequal variances, we develop matching priors and reference priors for a linear combination of the means. Here, we find three second-order matching priors: a highest posterior density (HPD) matching prior, a cumulative distribution function (CDF) matching prior, and a likelihood ratio (LR) matching prior. Furthermore, we show that the reference priors are all first-order matching priors, but that they do not satisfy the second-order matching criterion that establishes the symmetry and the unimodality of the posterior under the developed priors. The results of a simulation indicate that the second-order matching prior outperforms the reference priors in terms of matching the target coverage probabilities, in a frequentist sense. Finally, we compare the Bayesian credible intervals based on the developed priors with the confidence intervals derived from real data.

我国重大刑事冤案成因分析及应对策略——以公安司法机关的绩效考核机制为视角

近些年来,我国刑事司法领域发生了许多重大刑事冤案,危害极大,比较典型的如赵作海杀人冤案、佘祥林杀妻冤案等.刑事冤案的发生原因错综复杂,现行公安司法机关的绩效考核机制便是其中之一.文章以应对重大刑事冤案的发生为出发点,我国公安司法机关的绩效考核机制存在着一些不足,需要加以优化.只有建立了良好的法治观念与法治环境,构建完善的法律制度,才能从根本上遏制赵作海杀人冤案这样的人间悲剧再次发生.

South Korean College Students' Holland Types and Career Compromise Processes

This study explored South Korean college students' career compromise processes and examined whether preferences for sex type, prestige, or interests would be differentiated by Holland theme interest types, gender, or college major. Participants were South Korean undergraduate students from 2 universities in Seoul, South Korea. They were asked to choose 1 occupation from each of 168 pairs of occupations using a forced‐choice format. A total of 376 surveys were analyzed. There were significant main effects for Holland interest types and for gender but not for college major on their career compromise processes. Implications for career counselors and researchers are discussed.     

A Study of Battered Women’s Purpose of Life and Resilience in South Korea

The principal objective of this study is to determine whether battered women’s purpose of life (meaning/value) affects resilience (self‐efficacy/communication efficiency/optimism). This purpose is meaningful in that it may help provide battered women with a new perspective of a changeable life, away from the negative perspectives frequently associated with domestic violence sufferers. The subjects of this study were 110 battered women staying at shelters located in Seoul and Gyeonggi Province, Korea. The survey was conducted between August 15 and September 20, 2010. The data were collected using questionnaires measuring sociodemographic variables, a purpose‐of‐life scale, and a resilience scale. The collected data were evaluated with frequency, correlation, and multiple regression analysis. The results of this study can be summarized as follows. First, the meaning and value of life positively influenced self‐efficacy. Second, only the meaning had a beneficial effect on communication efficiency. Third, only the value variable positively affected optimism. Therefore, this study implied that resilience is an important area in the context of spousal abuse. Based on these results, a program for enhancing the meaning of life is suggested to help domestic violence survivors to build up resilience.     

多圈层——中心辐射式选题策划模式

目前选题策划在我国出版界处于起步和尝试阶段,受到出版界的高度重视.本文在对比分析若干策划模式利弊的基础上,提出一种"多圈层-中心辐射式"的选题策划模式.该模式是指建立以社长、总编为核心、以编辑室主任和发行部门负责人为骨干、以广大编辑为补充的三层策划网络系统.该模式强调全编辑职能扩展,能够调动各层面人员的积极性,形成选题策划合力,避免或减少人员之间的感情隔阂和选题策划的盲目性.
