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

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

In a content analysis of movie violence, we randomly selected twelve top-grossing American war films from four decades (1970 to 2002). We coded for implements of violence, length of violence, gore, and violence directed at noncombatants. We hypothesized that recently released war movies would be more violent than those released earlier. We found that films released since 1990 did contain more violence compared to others. Further, the intensity of gore increased in recently released movies. 相似文献

The relative earnings growth for immigrants in Norway is computed. Unlike Hayfron (1998, this journal) we define immigrants
by country of origin rather than citizenship and perform separate studies of immigrants from inside and outside the OECD region.
Replicating Hayfron op.cit. we find that the earnings assimilation is considerably weaker. Further, we find that the earnings
of OECD immigrants are comparable to those of natives, while Non-OECD immigrants earn considerably less than natives at the
time of entry, but that their relative earnings improve gradually over time. Earnings of different immigrant cohorts converged
from 1980 to 1990, indicating a non-linear rate of assimilation.
