Continuity and Change in the Family System Across the Transition from Adolescence to Emerging Adulthood

As adolescents move into emerging adulthood, their social networks shift toward a focus on peers and romantic partners, yet parents and siblings remain important sources of support. The present review takes a family systems approach to integrate the growing body of literature examining longitudinal continuity and change in both positive (e.g., intimacy, support) and negative (e.g., conflict, rivalry) qualities of parent–child and sibling relationships as adolescents transition to emerging adulthood. In general, contact with family members decreases, yet the quality of family relationships appears to improve or, at the very least, stabilize across this transition. These pathways are interpreted within the lens of several prominent theories, and a discussion of the limitations of the current literature and ideas for future research are presented.     

Courage in the Telling: The Critical Rise and Fall of David Leavitt

Openly gay American fiction writer David Leavitt, who had received positive reviews for his previous novels and short story collections, was sued in 1993 over his novel While England Sleeps by English poet Stephen Spender, who claimed that Leavitt plagiarized an episode from his own 1951 memoir World Within World, and grafted pornographic fantasies onto his biography. The accusations created a homophobic backlash against Leavitt, whose career has yet to recover fully. The result is that Leavitt, who had once been viewed as the one gay writer to find a footing in the mainstream literary community, is now firmly positioned in the gay literary subgenre and his work categorized as such. This essay examines book reviews in order to illustrate the difficulties that a writer who deals with gay life frankly and unapologetically finds in being accepted by the mainstream literary establishment, no matter how normal or assimilationist he or others might perceive his work to be.     

Use of balanced bipartite weighing designs as chemical balance designs

This paper deals with the use of balanced bipartite weighing designs as chemical balance designs when there Is a restriction on the number of objects that can be placed on either pan..The variance of each estimated weight and the covarlance of each pair of estimated weights are worked out.The use of additional weighing when the design matrix is singular is discussed.     

A re-evaluation of random-effects meta-analysis

Summary.  Meta-analysis in the presence of unexplained heterogeneity is frequently undertaken by using a random-effects model, in which the effects underlying different studies are assumed to be drawn from a normal distribution. Here we discuss the justification and interpretation of such models, by addressing in turn the aims of estimation, prediction and hypothesis testing. A particular issue that we consider is the distinction between inference on the mean of the random-effects distribution and inference on the whole distribution. We suggest that random-effects meta-analyses as currently conducted often fail to provide the key results, and we investigate the extent to which distribution-free, classical and Bayesian approaches can provide satisfactory methods. We conclude that the Bayesian approach has the advantage of naturally allowing for full uncertainty, especially for prediction. However, it is not without problems, including computational intensity and sensitivity to a priori judgements. We propose a simple prediction interval for classical meta-analysis and offer extensions to standard practice of Bayesian meta-analysis, making use of an example of studies of 'set shifting' ability in people with eating disorders.

基于情感倾向和观察学习的在线评论有用性影响因素研究

已有在线评论的研究都在消费者不能针对同一商品分开做正面评价和负面评价的实践背景下开展, 但类似于"中关村在线" 的评论系统已经允许消费者分别做正负两种评论, 并允许客户进行晒单, 本文主要研究这种区分在线评论的正负型评论及基于晒单的观察学习行为对有用性的影响. 结论表明: 区分背景下的在线评论极端性、 在线评论长度和晒单行为等都对在线评论的有用性产生显著影响, 负面在线评论的影响要大于正面在线评论.     

21世纪以来代表性神话学家研究评述

21世纪以来,神话学获得了新的发展。当下富于代表性的欧美和东亚神话学家的研究成果,具有以下显著特点:一些传统的研究视角和方法,依然保持着旺盛的生命力;涌现出不少反思之作以及新的理论视角和方法;"神话"的边界依然流动不羁,因此在就神话进行学术对话时,必须明了所讨论概念的意涵及其所发生的语境;神话与科学之间的关系得到进一步探讨,20世纪视神话与科学为和谐互容的观点得到进一步深化,神话遵从于科学的情形遭到质疑。神话学不应一味将眼光投向遥远的过去,而应研究神话与当下现实生活的深度关联。
