Despite growing concerns about foster placement instability, little information is available regarding the longitudinal patterns of placement histories among foster children. The purpose of the present study was to develop a charting system using child welfare records to facilitate a better understanding of longitudinal patterns of placement history for 117 foster children. The resulting Placement History Chart included all placements that occurred during the observed time period and accounted for various dimensions: number, length, type, and sequence of placements; timing of transitions; and total time in out-of-home care. The Placement History Chart is an effective tool for placing foster care experiences within a broader developmental context. As such, the Placement History Chart can be a valuable research tool for understanding various dimensions and variations of placement transitions among foster children by capturing sequences and cumulative risks over time. Furthermore, this chart can facilitate the development of intervention programs that are developmentally sensitive and effectively address particularly vulnerable subpopulations of foster children. 相似文献

Identity politics and citizenship are often envisaged in dichotomous terms, but cosmopolitan theorists believe commitments to ??thin?? universal values can be generated from divergent ??thick?? positions. Yet, they often gloss over the ways in which the nexus of thick and thin is negotiated in practice??a weak link in the cosmopolitan argument. To understand this nexus better, we turn to women??s rights organizations (WROs) in polarized Turkey to show that women affiliated with rival camps (e.g., pro-religious/pro-secular, Turkish/Kurdish, liberal/leftist) can mobilize over issues like empowerment, violence against women, and education. However, thick readings of these issues inflect upon collaboration. This has spurred pro-religious and Kurdish women to develop strategies that flag their specific concerns. As such, mutual recognition along cosmopolitan lines appears possible??and is reinforced through iterative encounters??but is not necessarily negotiated between equally empowered agents and entails complex processes of contestation and concession-making. 相似文献

Abstract In this paper, I focus attention on one aspect of business social responsibility, the relationship between businesses and community. Specifically, I explore the impact of business operators' perceptions about norms of collective action in their communities on the level of their support for and commitment to their communities. This relationship was elaborated using data from interviews with 1,008 business owners and managers randomly selected from 30 small Iowa communities (500 to 10,000 in population). Findings indicate the majority of small business operators report that they are committed to and provide support for their community. Also, it is concluded that operators' educational levels and lengths of residence, the success and age of their businesses, and their perceptions of community levels of collective action are significantly associated with levels of business social responsibility. 相似文献

ON BOOTSTRAP HYPOTHESIS TESTING 总被引:2,自引:0,他引:2
We describe methods for constructing bootstrap hypothesis tests, illustrating our approach using analysis of variance. The importance of pivotalness is discussed. Pivotal statistics usually result in improved accuracy of level. We note that hypothesis tests and confidence intervals call for different methods of resampling, so as to ensure that accurate critical point estimates are obtained in the former case even when data fail to comply with the null hypothesis. Our main points are illustrated by a simulation study and application to three real data sets. 相似文献

Influenced by the consumerist sentiment in New Public Management,the last decades have witnessed a revival of the call for accountabilityto service users in the public service sector. As an act ofaccountability, social care and health care professionals areincreasingly obliged to involve their service users in the serviceplanning and monitoring process. Despite the popularity of thisaccountability and user involvement rhetoric, critics have,however, been skeptical of the prevailing user involvement initiativesas an effective measure of accountability to service users (Barnes and Wistow, 1994a,1994b; Bowl, 1996; Peck et al., 2002; Rea, 2004). Based on astudy of user involvement in the welfare sector of Hong Kong,this paper argues that the discourse of accountability to theservice users can be a source of unrest for welfare professionals,in the manifestation of accountability as a power relationship.Their ensuing response is to accommodate the ensuing challengearising from the demand for accountability to service usersby manoeuvring the accountability discourse. It is the contentionof this paper that the institutional inclusion of welfare serviceusers into a discursive space is a necessary but not sufficientcondition for the realization of a mandate of accountabilityto welfare service users. 相似文献

Interval-censored data arise in a wide variety of application and research areas such as, for example, AIDS studies (Kim et al ., 1993) and cancer research (Finkelstein, 1986; Becker & Melbye, 1991). Peto (1973) proposed a Newton–Raphson algorithm for obtaining a generalized maximum likelihood estimate (GMLE) of the survival function with interval-cen sored observations. Turnbull (1976) proposed a self-consistent algorithm for interval-censored data and obtained the same GMLE. Groeneboom & Wellner (1992) used the convex minorant algorithm for constructing an estimator of the survival function with "case 2" interval-censored data. However, as is known, the GMLE is not uniquely defined on the interval [0, ∞]. In addition, Turnbull's algorithm leads to a self-consistent equation which is not in the form of an integral equation. Large sample properties of the GMLE have not been previously examined because of, we believe, among other things, the lack of such an integral equation. In this paper, we present an EM algorithm for constructing a GMLE on [0, ∞]. The GMLE is expressed as a solution of an integral equation. More recently, with the help of this integral equation, Yu et al . (1997a, b) have shown that the GMLE is consistent and asymptotically normally distributed. An application of the proposed GMLE is presented 相似文献

Research into the health and wellbeing of rural lesbian, gay, bisexual, and transgender (LGBT) populations is limited. A community-based participatory research (CBPR) approach was used to develop an online survey for LGBT Nebraskans. The 770 participants replied to an array of questions on social determinants of health and basic health outcomes. Only significant differences in having health insurance were found between urban and rural participants. Social determinants of health were explored. Results of this study suggest that regional culture may be more salient to health for lesbian, gay, bisexual, and transgender persons living in the Midwest than rural or urban residence. 相似文献
