Occupational conditions and workers' sense of community: Variations by gender and race

The literature is reviewed to define a sense of community in the workplace and to identify factors that may foster it. A model is developed and estimated with survey data from a culturally diverse sample of men and women performing lower-level jobs at a medium-sized manufacturing firm. Results of regression analyses are reported that correct for sample selection bias resulting from the lower response rates of minority workers. Findings suggest that well-designed jobs and supportive workplace relationships and policies are important in explaining workers' sense of community, defined as workers' perceptions of mutual commitment between employee and employer. Informal sources of support play a larger role in explaining men's sense of community, while formal sources of support are more important in explaining women's sense of community. Findings further suggest that African American workers, especially women, have a difficult time experiencing a sense of community at work.

The matryoshka: The three-generation soviet family in Israel

Among the 200,000 immigrants who entered Israel in 1990 were a considerable number of families headed by single mothers. Their most prominent feature was the fact that a three-generation system—a single Soviet mother, her own mother, and a single child—formed the family unit. Rooted in changes occurring in the Soviet family life cycle over the past 70 years, this configuration is uniquely self-contained. This article is an early inquiry into a new family structure that will become part of the social fabric of the multi-ethnic society in Israel. The challenge will be to help in the absorption process by recognizing, encouraging, and facilitating the strengths this type of family brings with it and to plan support networks to substitute for those left behind.A previous version of this article was presented at the Third World Family Therapy Congress, June 2–6, 1991, Jyvaskyla, Finland.     

Wisdom and abiding interest: Interviews with three noted historians in later life

This article explores the connections between wisdom-related attributes and abiding interest and draws upon material from interviews with three eminent historians in later life. It is proposed that one characteristic of wisdom, namely, the coordination of affective/attaching and cognitive/detaching modes of processing information, is related to abiding interest or the ability to self-regulate attention in a way that promotes lifelong learning. The article (a) reviews pertinent constructs in the literatures on adult development and wisdom; (b) presents selected excerpts from in-depth interviews; and (c) concludes by discussing the developmental implications of the ideas presented.     

Parenting stress in parents of children with attention-deficit hyperactivity disorder and parents of children with learning disabilities

Parenting a child with ADHD can challenge parenting resources and coping. Increasingly, researchers are examining the relationship between the behavior of the child with ADHD and family functioning. While studies have shown inceased parenting stress in parents of children with ADHD, these studies have compared children with ADHD to non-disabled children. This study compares reports of parenting stress among mothers of children with ADHD, mothers of children with learning disabilities and mothers of non-referred children. Results showed that parenting stress was highest for mothers of children with ADHD. Increased parenting stress was associated with child characteristics and, in particular, with externalizing behavior problems.

幼儿从电视中学单词──项伴随学习的研究

对幼儿从电视中伴随学习单词的可能性及其影响因素进行了初步的探讨。４０名小班幼儿和４６名大班幼儿参加了实验,他们在接近自然的状态下观看有字幕的动画片。结果发现：幼儿在无任何指导的情况下观看有字幕的动画片,能伴随学习到汉字,这表明,电视对幼儿的词汇发展有着积极的影响;不同性别的儿童都能同等程度地从电视中伴随学习到单词;词义的伴随学习受幼儿原有的词汇水平和幼儿对目标词熟悉程度的影响;词音的伴随学习只发生在词汇水平较高的幼儿当中,并且随着幼儿对目标词熟悉程度的增加而增加;词音和词义的伴随学习存在频度效应。     

合作学习对小学生同伴关系、成就动机和成就影响的研究

旨在探讨在我国开展合作学习教学的可行性,以及合作学习对小学生同伴关系、成就动机和成就水平的影响,运用自然实验和测量相结合的方法,选择了北京师范大学实验小学三年级两个班进行实验研究,其中一个班为实验班（ｎ＝３５）,另一个班为控制班（ｎ＝３７）．实验为期三个月。结果表明：合作学习在小学教学中不但是可行的,而且效果较为显著;合作学习对同伴关系的改善有着积极的影响,学生间的接纳度和被接纳度都有普遍的提高;合作学习在较大程度上激发了学生的成就动机水平,学生对合作学习的课程兴趣明显提高．成绩较差的学生表现得更为明显;合作学习对提高学生的学习成绩有一定的促进作用。     

Brain dynamics,psychophysiological uncertainty and behavioral learning

The present paper takes a first step toward the integration of recent findings on brain dynamics and learning into established fields of psychophysiological science. Leading-edge studies of brain dynamics have shown that the brain manifests an inherent variability and that, when new stimuli (i.e., “problems”) are presented to the organism, brain chaos increases.     

Role of the striatal cholinergic system in the regulation of learned manipulation in rats

The experiments were performed on adult Wistar male rats trained to push with the forepaw on a fixed piston inside a narrow tube. It was found that after localized intracerebral injection of a cholinergic antagonist into the dorso-lateral (but not medial) neostriatum (i.e., the caudato-putamen) the behavioral performance requiring brief innate movements remained unchanged, but the performance requiring a prolonged pushing movement (> 50 msec) became disrupted. Microinjection of carbacholine (0.03-3 μ g/1 μ1) did not affect the performance of the acquired movements, whereas scopolamine (3 μ g/1 μ1) led to the significant decrease in pushing time. We conclude that changes in the state of the dorso-lateral neostriatal cholinergic system result only in disturbances of the sensory-controlled component of a complex instrumental movement. The 1994 Pavlovian Society Young Investigator Awardee was Nadezda Dubrovskaya, first author of this paper, which was presented at the annual meeting of the Pavlovian Society, July 3, 1994, in Prague, Czech Republic.     

Social integration and social support in a life crisis: Effects of macrosocial change in east Germany

This process evaluation study examined what variables moderate and mediate treatment effects on days in stable housing and client satisfaction for homeless mentally ill clients. In general, demographic characteristics did not moderate either outcome variable. Housing contacts, entitlement contacts, mental health contacts, and supportive services were significant mediators of the treatment effect on days in stable housing. Program contacts, mental health contacts, and supportive services were significant mediators of client satisfaction. The authors thank the National Institute of Mental Health for their financial support (MH43248, MH42357) for this project, Dorothy Gano for word processing and editorial assistance, and Gitry Heydebrand, Melissa Dannelet, Betty Tempelhoff, Ruth Smith, and Laeeq Ahmad for assisting in the interviews of clients. We are also appreciative of the cooperation given to us by the staffs of Malcolm Bliss Mental Health Center, St. Patrick's Center, the Community Advocacy and Support Alliance Program, and the St. Louisemergency shelters. Finally, we thank all of the participants in this study; we hope that their homelessness has now ended.
