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 study investigates the use of and satisfaction with child care among low-income families, who are those likely to be affected by recent changes in public policy that emphasize increased work effort. Data from the Survey of Wisconsin Works Families portray differences in the use of center-based care depending on whether or not the family received a child care subsidy. A multivariate analysis of a measure of parental satisfaction, whether a parent would switch child care sources if all care were available at no charge, suggests that parents tend to be more satisfied with center-based care than with alternative forms of care. The analysis also suggests that mothers who received a child care subsidy were significantly more likely to have their children in center-based care.  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

Elements of attachment theory have been embraced by practitioners endeavouring to assist foster and adopted children and their parents. Attachment theory articulates the potential risks of experiencing multiple caregivers; emphasizes the importance of close social relationships to development; and recognizes that substitute parents may not always have close relationships with children who have experienced adversities before joining them. Attachment theory offers concerned parents what they believe to be a scientific explanation about their lack of the close, satisfying parent–child relationship they desire. Yet the scientific base of attachment theory is limited both in terms of its ability to predict future behaviours, and especially with regard to its use as the underpinning theory for therapeutic intervention with children experiencing conduct problems. There is a critical need to review the role of attachment theory in child and family services and to consider its place among other explanations for children's disturbing behaviour. An important step towards pursuing alternative approaches is for researchers and practitioners to understand the reasons the attachment paradigm appeals to so many adoptive and foster parents, given the apparent widespread prevalence of attachment‐based interventions. Such understanding might assist in the development of adoption‐sensitive uses of appropriate evidence‐based treatment approaches.  相似文献

This article examines the Program Assessment Rating Tool (PART)in the federal budgeting process. The early evidence on PARTprompts the search for a theory of budgeting that accepts thatperformance information will influence decisions but will notbe used in the same way from decision to decision, as the espousedtheory of performance budgeting suggests. Dialogue theory emphasizesthe ambiguity of performance information and related resourceallocation choices. An exploratory test of dialogue theory isundertaken through an experiment involving graduate studentsassessing PART evaluations. The results illustrate a varietyof ways in which different individuals can examine the sameprogram and, using logical warrants, come to different conclusionsabout performance and future funding requirements.  相似文献

Behavioral and electrophysiological evidence suggests a gradual, experience‐dependent specialization of cortical face processing systems that takes place largely in the 1st year of life. To further investigate these findings, event‐related potentials (ERPs) were collected from typically developing 9‐month‐old infants presented with pictures of familiar and unfamiliar monkey or human faces in 2 different orientations. Analyses revealed differential processing across changes in monkey and human faces. The N290 was greater for familiar compared to unfamiliar faces, regardless of species or orientation. In contrast, the P400 to unfamiliar faces was greater than to familiar faces, but only for the monkey condition. The P400 to human faces differentiated the orientation of both familiar and unfamiliar faces. These results suggest more specific processing of human compared to monkey faces in 9‐month‐olds.  相似文献
