The basic methodology of behavior genetics is described in the context of the twin and sibling/adoption design. Results of applying this model to cross-sectional data on cognitive development throughout the lifespan are presented. Results from a large longitudinal twin and adoption study of general intelligence are presented to illustrate the use of the basic behavior genetic model in studying the causes of continuity and change in development. A special model is presented for the study of abnormal behavior occurring at the extremes of the distribution and an adaptation of the model is discussed for the study of genetic linkage or the mapping of quantitative trait loci (QTL). Results of applying this model to a sample of twins and kindred siblings indicated the presence of a major QTL for dyslexia on chromosome 6. The purpose of the paper is to illustrate the scope of behavior genetic methodology in studying individual differences in behavior in a biosocial context. 相似文献

This paper reviews some of the issues in child abuse such as problems of definition, characteristics of abuser and abused, and etiology. It emphasizes that child abuse can start at any age. A developmental approach is suggested in order to understand the relationship between the child's stage of development and its idiosyncratic potential for stimulating aggression on the part of the parent. This approach offers a broad framework in which phase specific stressors, characteristics of the child, the abuse prone personality of the abuser, as well as the family system and external stress factors, can be considered together and upon which intervention strategies can be planned.Lynn Ohrenstein is Administrative Supervisor at the Jewish Board of Family and Children's Services, a doctoral candidate at Yeshiva University, and in private practice.This is an expanded version of a paper delivered November 4, 1982 by the author at an interdivisional meeting at the Jewish Board of Family and Children's Services devoted to Issues on Domestic Violence. 相似文献

A health-oriented interactional model of adolescent change in times of transition is presented. Four factors are discussed: 1. the effect of individuals and the environments on each other; 2. the interactive flow between regression and growth, vulnerabilites and competencies, crisis and equilibrium; and 3. the interactive effects of psychological, social and physical factors. A social work assessment and intervention model is built on this framework.Ms. Lammert is an Associate Professor, National Catholic School of Social Service, a consultant to the American Digestive Disease Society and to the Christ Child Society School Counseling Program and in private practice. 相似文献

This paper presents the viewpoint that congenitally physically children, having never been nondisabled, may experience themselves disabled yet intact, with the disability an integral part of their identity. However, society, with its pervasively negative attitudes toward disability, perceives disabled people as incomplete, defective, and deviant. Hence, congenitally disabled children face the difficult dilemma of integrating these two divergent views of themselves. Parents and professionals are offered guidelines to facilitate the resolution of this dilemma; however, they must first carefully scrutinize their own attitudes toward disability so that these do not unwittingly impede the parenting and treatment processes.Harilyn Rousso is director, Disabilities Unlimited, Counseling and Consultative Services; consultant on women and disability, YWCA of N.Y.C.; chairperson, Association of Mental Health Practitioners with Disabilities. 相似文献

The psychophysical conditions of 15 young female nurses, working in a rapidly-rotating shift system (2-2-2-2), modified according to some psychophysiological criteria, and exposed to short period (4 × 20 min) of bright light (2350 Lux) during their night duty, were studied in order to evaluate their adaptation to night work and to test a possible positive effect on it of bright light. Subjective evaluations of work load and psychophysical conditions, performance measures, hormonal excretion (cortisol, 6-sulphatoxymelatonin and catecholamines), oral temperature and activity-sleep logs were taken during the shiftwork cycle, comprising one morning, one afternoon and two consecutive nights under normal and bright light. The results showed that this rapidly-rotating shift system had little effect upon the normal circadian rhythms of the body. Moreover, the lengthening of the night shift to 10 h can be considered to be acceptable, provided that work load is reduced and there are sufficient rest pauses available. On the other hand, the reduction to 7 h of the length of the day shifts and delayed start of the morning shift to 07:00 h appeared to be convenient both in relation to the work load and sleep duration. Some positive effects of bright light upon psychophysical conditions and performance efficiency were noted, while hormonal excretion and body temperature did not show any effect of bright light; in particular, melatonin excretion was not suppressed appreciably by the bright light used. 相似文献

Abstract In recent years, several agricultural cooperatives have undergone significant restructuring. Some have been taken through a conversion process and have been reorganized as “investor-oriented firms” (IOFs). This phenomenon has attracted the interest of agricultural economists, but it has not been analyzed by sociologists. This article examines the discourse with which agricultural economists have approached the conversion issue. Drawing upon Fraser's discussion of “needs talk,” and inspired by Kloppenburg's analysis of the agricultural scientific complex, an argument is made that a reprivatization discourse of neoclassical economics has effectively depoliticized discussion about the future of cooperative enterprise. It is further argued that a repoliticization of cooperation is necessary in order to assure the protection of extra-economic values and oppositional discourse that is embedded in the historical development of cooperative practices and institutions. We focus here on the role of expert discourse as it relates to the reinvention of cooperative institutions in the agricultural economy. It is argued that this discourse would be improved by greater attention to historical and sociological forces, rather than remaining narrowly focused on economism. 相似文献

Frequency of Citations as Criterion for the Ranking of Departments, Journals, and Individuals 总被引:1,自引:0,他引:1
Interest in the structure and dynamics of sociology as a discipline has led to recurrent attempts to measure the prestige, productivity, and quality of education of the various sociology departments. While several previous papers have suggested the potential value of the Science Citation Index (SCI) as a measure of scientific standing, few attempts have been made to utilize a citation-based measure of scientific prestige. This paper considers the meaning of the citation in science and in stratification theory. Procedures are described whereby citations to individual sociologists and journals are employed to yield rankings of departments of sociology and journals. The differences between these rankings and other rankings are discussed. 相似文献
