The major objective of this article is to report the findings of two studies which compare and contrast the early child-rearing practices of two generations of Punjabi parents (1970s and 1990s) living in England. Additionally, the findings are compared with a small group of white mothers to broaden our understanding of the changing patterns of parenting. The data was collected through in-depth semi-structured interviews from the first generation during the period 1970–73 and from the second generation in 1995. The research perspective adopted is a qualitative one in that variables and procedures for data collection are not rigorously controlled, and the narratives of the mothers are used extensively to illuminate the key areas of early child rearing. The findings show that the second-generation mothers are shedding most of the traditional customs and practices and are moving towards modern British ways.  相似文献

Despite frequent references in the sociological literature to Durkheim's theory about the division of labor, sociologists have made few attempts to test it. The paucity of attempts and the very debatable outcomes thereof are due largely to Durkheim's use of the traditional discursive mode of theory construction. A discursively stated theory's logical structure is likely to be obscure, and for that reason alone tests of it are difficult and controversial. Rather than perpetuate the exegetical tradition in sociological treatments of the subject, this paper restates Durkheim's theory in accordance with a particular formal mode. That restatement identifies the theory's shortcomings and problems. But the eight premises imply only one testable theorem, and the theorem's predictive accuracy appears minimal unless "population concentration" is substituted for "density" in the first axiom. Nonetheless, the restatement clearly shows how extension of the theory (additional postulates) could further its testability.  相似文献

A wide body of literature documents the effect of social networks and social supports on mental health. Fewer studies, however, have examined the reciprocal effect of mental health on social relationships. This problem is examined using data from a national panel survey of adults aged 20-64. For the sample as a whole, support was found for a social selection process, since psychological distress predicted decreases in primary, but not secondary, social relationships. The extent of primary relationships also were found to be associated with subsequent distress, providing evidence that the relationship between mental health and social environment may be transactional. When examined separately by gender, males but not females were found to be vulnerable to the process of social selection, supporting the hypothesis that the expression of distress is less role-appropriate for men and therefore more likely to invite social sanctions. Social causation effects also were observed only among males.  相似文献

This paper is concerned with an exploration of the role of the long range planner, whether in the private or public sector of the economy, and the impact made upon the processes of his work by government's increasing propensity to manipulate the economy. The authors' researches over the last 2 years into the comparative nature of planning processes in the U.K. economy have made it abundantly clear to them that planners are increasingly concerned at the dangerous potential of such impact upon their forecasting procedures. The emphasis here will rest upon the planner in private enterprises, although the authors' work in both local government and the nationalized enterprises suggest that the problem is of equal importance in these sectors.The authors consider first the past nature of the search processes in long range planning and the context of such attempts to narrow down the range of variables that form the enterprise's perception of its future. Secondly, they examine the emerging discontinuity and the changing role of government, with particular reference to indicative planning concepts. Then they introduce some of the findings of a recent survey of attitudes towards long range planning in the construction industry of the U.K., a sector vitally influenced by turbulence in the economy and with particular interest in government's ideas of macro-planning. Finally Edwards and Harris examine the implications to government and to planners of their findings.  相似文献

As the first article of a two-part series, the purpose of this paper is to examine the functional factors that contribute to automobile accident occurrence and to model the causation structure in the form of a fault-tree. The fault-tree model provides an intuitive framework for qualitatively decomposing possible pathways to accident occurrence. Fault-tree analysis also provides a statistical representation of how interacting driver, vehicle, and environmental factors contribute to the likelihood of automobile accident occurrence. The application of this model facilitates pinpointing those factors that most contribute to accident causation and subsequently enables the identification and comparison of potential crash avoidance technologies.  相似文献

Objective. To understand how adaptation/assimilation, disruption, and diffusion interact to produce changes in fertility levels among successive generations of Mexicans and Central Americans in the United States. Method. Using restricted access data that link individual data (CPS) to neighborhood data (census tracts), we examine the role of generation, personal characteristics, and neighborhood characteristics in determining children ever born (CEB). Results. There are significant differences in fertility across generations and, to a lesser extent, between women who live in ethnic enclaves and those who do not. Once personal characteristics are considered, the independent effect of generation on fertility is nearly eliminated. Personal characteristics dominate neighborhood characteristics in their ability to predict fertility. The most consistent predictor of CEB at the neighborhood level is the percentage of Hispanic adults. Conclusions. Personal characteristics dominate fertility change across generation, and were it not for increases in educational attainment, fertility might be higher in successive generations rather than lower or unchanged.  相似文献

1. Brief planned and crisis admissions to an inpatient psychiatric unit are presented as a component supportive of outpatient care and case management for chronically mentally ill patients. 2. Typical patients admitted to this inpatient short-term program are those experiencing a life stress or temporary crisis; chronically mentally ill patients who cycle and experience exacerbations of their illness; and those who need to make the transition from an acute inpatient unit to community living. 3. The Brief Admission Program treats the individual's response to and the consequences of a lifelong illness and enables the patient to return to his previous level of functioning and continue necessary outpatient treatment.  相似文献

The aim of this article is to pinpoint the relevance of family relationships in the studies on ‘social capital’. In order to clarify this perspective, Pierpaolo Donati outlines a new approach called ‘relational approach’. According to it, social capital is a property and a quality of social relationships, not an attribute of individuals or social structures as such. This theory has two major advantages: first, it leads to differentiate those components of social capital which are usually conflated; second, it permits to identify various forms of social capital (primary, secondary-communitarian and civic or generalized). Riccardo Prandini criticizes the sociological prejudices which consider the family mainly as an obstacle for the full deployment of ‘liquid’ and ‘modern’ social relations. The family's social capital is defined as the reciprocal orientations of the family's members which are able to generate trust and therefore cooperative actions. Empirical evidence shows that the family's social capital is strictly connected to the emergence of pro-social attitudes in individuals, particularly in terms of social trust and participation in civil associations.  相似文献
