This paper presents a review of the literature on the meaning, etiology and categorization of acting out symtomatology in children. It is apparent that there is no one cause nor is there one well defined disorder.DSM-III categories as they relate to behavior disorders are discussed and the problems of diagnosis are addressed. Appropriate treatment goals and interventions cannot be developed unless more global aspects of a child's functioning and the environment in which he lives are assessed. 相似文献

This paper presents a preliminary report of the results of a project investigating discourse used in research, treatment and theory in the area of family violence. An overview of the understandings of family professionals in the field is set forth. In addition, the results of the analysis of family violence discourse and the direction of future research are discussed.> 相似文献

This paper examines the work and care strategies chosen by full‐time working families with children in Finland, Italy, Portugal and the UK. It asks whether European families in different countries, facing the same problems of balancing employment and childcare responsibilities, respond to their situations in similar ways. An increase in dual‐earner families where both parents work full‐time represents a general employment trend in today's Europe. Also, within families with children, such employment patterns are now more common than they were previously. National differences may therefore not any longer be as marked as often indicated by country‐based surveys. The qualitative data from the SOCCARE Project offer a way to examine this issue. The focal point of the paper is to make a comparative analysis of couples in similar work and care situations. Using their working hours as the common denominator, this paper analyses their daily childcare arrangements and how these are impacted by gender roles, working schedules, flexibility of workplace, income levels, parents’ educational background and availability of care facilities. The paper concludes that European families’ work and care strategies have many similarities whereby national differences may not be as marked as often indicated by contemporary research. 相似文献

Summary. The paper analyses a time series of infant mortality rates in the north of England from 1921 to the early 1970s at a spatial scale that is more disaggregated than in previous studies of infant mortality trends in this period. The paper describes regression methods to obtain mortality gradients over socioeconomic indicators from the censuses of 1931, 1951, 1961 and 1971 and to assess whether there is any evidence for widening spatial inequalities in infant mortality outcomes against a background of an overall reduction in the infant mortality rate. Changes in the degree of inequality are also formally assessed by inequality measures such as the Gini and Theil indices, for which sampling densities are obtained and significant changes assessed. The analysis concerns a relatively infrequent outcome (especially towards the end of the period that is considered) and a high proportion of districts with small populations, so necessitating the use of appropriate methods for deriving indices of inequality and for regression modelling. 相似文献
