Bayesian estimates in a one-way ANOVA random effects model

Bayesian estimators of variance components are developed, based on posterior mean and posterior mode, respectively, in a one-way ANOVA random effects model with independent prior distributions. The formulas for the proposed estimators are simple. The estimators give sensible results for 'badly-behaved' datasets, where the standard unbiased estimates are negative. They are markedly robust as compared to the existing estimators such as the maximum likelihood estimators and the maximum posterior density estimators.     

邓小平的社会主义本质论新探

“社会主义本质”是一个具有创新意义的总体性范畴。邓小平对社会主义本质的哲学表述,是一个有着内在的严密逻辑关系的整体。社会主义本质论既包括了社会主义社会的生产力问题,又包括了以社会主义生产关系为基础的社会关系问题;既指出了社会主义的根本任务,又指出了社会主义的根本目的和未来发展方向。实现社会主义本质,是一个动态的发展过程。     

学术腐败的期刊编辑控制

由于学术腐败对学术期刊的侵袭日趋严重,因此建立有效的编辑防范机制,遏止学术腐败在学术期刊中泛滥,已经成为学术期刊必须赢得的挑战。通过提升作者的学术规范意识,健全审稿程序,完善相关法律制度,构建起一套严格有效的编辑出版控制机制,把好学术成果的出口,学术期刊将会在规范学术研究,净化学术环境等方面发挥出独特的作用。

The Relationship Between Spiritual Well-Being and Health-Related Quality of Life in College Students

Abstract

Objective: This study investigated the relationship between spiritual well-being (SWB) and various aspects of health-related quality of life (HRQL) of college students. Participants and Methods: Two hundred twenty-five participants were surveyed during October 2010 to assess SWB and HRQL using the Spiritual Well-Being Scale and questions from the Centers for Disease Control and Prevention's scale for HRQL, respectively. Hierarchical multiple linear regression analyses tested the relationship between SWB and multiple measures of HRQL while controlling for sex, age, and race. Results: Participants who reported higher SWB scores were more likely to participate in religious-type activities and report better HRQL compared with students who reported a moderate sense of SWB. Jointly, SWB and participation in religious activities explained 18% of the variance in HQRL in this sample. Conclusions: SWB made a significant contribution to HRQL in a sample of college students. Such a relationship should be considered by campus health program planners to improve the quality of life of young adults.     

从形上之思到生存智慧--现代性状况与哲学存在的合法性根基

近代哲学在张扬理性、完成转向的同时,也失去了哲学传统中所具有的关注人类命运和价值的智慧之根,这导致了理性形而上学在不断拓进的同时,也疏离了人类的生存困境.本文试图表明,在现代性的人类生存状况下,理性形而上学必然走向衰落,而在近代哲学框架下各种探究"形上之思"的努力也必然归于失败,寻求关乎人类整体命运的生存智慧将成为现代哲学的立足点和合法性根基.     

面板数据随机前沿分析的研究综述

近年来,面板数据随机前沿分析（SFA）越来越多地被用于测算各类决策单位的效率,取得了很多成果,但是国内外实证研究文献也存在过度依赖几种假设严格的模型和不注重模型局限性的问题。本文在统一的计量框架下,对面板SFA模型的发展研究进行了系统的梳理总结。本文将相关模型分为两大类：效率不随时间变化的模型和效率可随时间变化的模型,每一类又根据是否对效率项的分布做出假设分为：有分布假设的模型和无分布假设的模型。在明确和比较不同模型的假设、估计过程和局限性的基础上,我们对未来面板SFA模型的应用提出了建议。     

Estimating parameters in autoregressive models in non-normal situations: symmetric innovations

The estimation of coefficients in a simple regression model with autocorrelated errors is considered. The underlying distribution is assumed to be symmetric, one of Student's t family for illustration. Closed form estimators are obtained and shown to be remarkably efficient and robust. Skew distributions will be considered in a future paper.

论小学英语师资愉快教育理念的培养

自"快乐教育"的理念提出后,受到了各国教育界的广泛关注,我国也提出了要从应试教育向素质教育转变的发展战略;随着经济的全球化,教育也要面向国际化.教育部规定,把小学开设英语课程作为21世纪基础教育课程改革的重要内容,教师只有对小学生的特征,小学生英语教学的特征和规律有清楚的认识,树立愉快教育的理念,才能保证这一目标的更好实现.
