Sponsored both by governments intent upon fiscal restraint anduser movements keen to extend choice and control, ‘cash-for-care’schemes are replacing direct services across mature welfarestates. Recent legislation on direct payments, which has enactedthe UK version of cash-for-care, has attracted considerableresearch interest in the UK. Previous studies point to a numberof tensions for social workers in the implementation processwhich give rise, in turn, to considerable uncertainty, evenhostility, on the part of front line staff. This article, whichdiscusses the findings of a study of assessment and care managementpractice in one English council, seeks to make sense of socialworkers’ approach to the allocation of direct paymentsby reference to Lipsky’s (1980) theory of ‘street-levelbureaucracy’. The author concludes that despite ten yearsof managerialism, in the course of which professional practicehas been routinized and regulated, Lipsky’s work is stilluseful in analysing front line behaviour around direct payments.  相似文献

This paper reports the first cross-study competitive test of thecore solution in side-payment games where the core is nonempty and nonunique (i.e., larger than a single point). The core was tested against five alternative theories including the Shapley value, the disruption nucleolus, the nucleolus, the 2-center, and the equality solution. A generalized Euclidean distance metric which indexes the average distance between an observed payoff vector and the entire set of predicted payoff vectors (Bonacich, 1979) was used as the measure of goodness-of-fit. Analysis of data assembled from six previously reported studies (encompassing a total of 1,464 observations over 56 3-person and 4-person side-payment games) showed the core to predict less accurately than the Shapley value, disruption nucleolus, and nucleolus solutions (p < 0.01). These findings are consistent with previous empirical results that show the core to have a low level of predictive accuracy in side-payment games.This research was supported by grants SOC-7726932 and SES-8015528 from the National Science Foundation. Data analysis was performed at the Madison Academic Computing Center.  相似文献

A heated debate about battered women who kill abusive male partners started in the 1970s. In this study, we tracked the public discourse on battered women who kill by coding 250 newspaper articles published between 1978 and 2002. Using four typifying models, we found that leading explanations for why battered women kill medicalized then criminalized their actions; they were mad then bad. We also found that reporters used quotes from claims makers supporting conventional or medical typifications of battered women to a much greater degree than statements from alternative, feminist sources. In conclusion, simplified, sensational and conventional understandings of crime causation drove the social construction of “the battered woman who kills”. She may be mad or bad, but rarely has she been portrayed as reasonable. Suggestions for promoting feminist narrative in the media are also provided.  相似文献

Fatherhood has traditionally been viewed as part of a “package deal” in which a father’s relationship with his child is contingent on his relationship with the mother. We evaluate the accuracy of this hypothesis in light of the high rates of multiple-partner fertility among unmarried parents using the Fragile Families and Child Wellbeing Study, a recent longitudinal survey ofnonmarital births in large cities. We examine whether unmarried mothers’ and fathers’ subsequent relationship and parenting transitions are associated with declines in fathers ’ contact with their nonresident biological children. We find that father involvement drops sharply after relationships between unmarried parents end. Mothers’ transitions into new romantic partnerships and new parenting roles are associated with larger declines in involvement than fathers’ transitions. Declines in fathers’ involvement following a mother’s relationship or parenting transition are largest when children are young. We discuss the implications of our results for the well-being ofnonmarital children and the quality of nonmarital relationships faced with high levels of relationship instability and multiple-partner fertiliy.  相似文献

Queer Treasons suggests how and why homosexuality has been placed outside the limited discourse of what constitutes ‘Irishness.’ I argue that, since the early part of the twentieth century, homosexuality has been represented as ‘foreign’ to nationalisms in Ireland, particularly when the borders of the nation are perceived to be under threat. I further suggest that the threat of homosexuals, as represented in Irish political discourse, points more generally toward an instability in the discourses of nation itself.  相似文献

Abstract

Objective: The purpose of this study was to identify the health topics students received information about, how students obtained health-related information, and perceived believability of those sources. Participants and Methods: Students (N = 1202) were surveyed using the National College Health Assessment (NCHA) of the American College Health Association. Results: Nearly half (46%) of the sample reported not receiving any information, whereas only 0.5% received information on all health topics. The Internet was the most common source of health-related information, but, conversely, was perceived as the least believable source. Health center medical staff and university health educators were perceived to be the most believable sources. Conclusions: Future practice at the university setting should focus on delivering health information through believable messengers utilizing the most commonly reported sources of information. This may have implications towards how students shape their health-related social cognitions and subsequent behaviors.  相似文献

This investigation examines the relationship between peer group acceptance and academic performance among adolescents participating in a dropout prevention program. Three variables assessing school-related attitudes and behavior are identified as potential links between peer group acceptance and academic performance and the results are examined in the context of the gender and racial/ethnic group identification of adolescent respondents. Peer group acceptance is found to have an indirect rather than a direct influence on academic achievement. The behavior variable, avoidance of problem behavior, provides the strongest path of connection between peer group acceptance and academic performance. Implications of the findings for social work practice in the school setting are discussed.  相似文献

Bayesian inference for pairwise interacting point processes   总被引:1,自引:0,他引:1  
Pairwise interacting point processes are commonly used to model spatial point patterns. To perform inference, the established frequentist methods can produce good point estimates when the interaction in the data is moderate, but some methods may produce severely biased estimates when the interaction in strong. Furthermore, because the sampling distributions of the estimates are unclear, interval estimates are typically obtained by parametric bootstrap methods. In the current setting however, the behavior of such estimates is not well understood. In this article we propose Bayesian methods for obtaining inferences in pairwise interacting point processes. The requisite application of Markov chain Monte Carlo (MCMC) techniques is complicated by an intractable function of the parameters in the likelihood. The acceptance probability in a Metropolis-Hastings algorithm involves the ratio of two likelihoods evaluated at differing parameter values. The intractable functions do not cancel, and hence an intractable ratio r must be estimated within each iteration of a Metropolis-Hastings sampler. We propose the use of importance sampling techniques within MCMC to address this problem. While r may be estimated by other methods, these, in general, are not readily applied in a Bayesian setting. We demonstrate the validity of our importance sampling approach with a small simulation study. Finally, we analyze the Swedish pine sapling dataset (Strand 1972) and contrast the results with those in the literature.  相似文献

Research indicates that girls' disadvantage in 1–4 mortality is unusually high inEgypt, yet the relevance of intra-family differences in power for the distributionof health resources is debated. This analysis compares effects of the involvementof various family members on choice of provider, place of care, and total expendituresfor curative care among 129 girls and boys with diarrhea in Minia, Egypt. Girlshave lower odds than boys of visiting doctors versus lay providers and privateversus informal facilities, and the involvement of fathers in prior discussionsabout care may be important to reduce this disparity. Median expenditures forcurative care also are lower for girls than boys, particularly when fathers arenever involved in choice of care. Future research should examine the extent towhich these disparities in care reflect differences in the quality of care received.  相似文献
