Objective. Many social scientists believe poor mothers are better off in middle‐class than in poor neighborhoods, partly because the latter are deprived of important institutional resources. We test whether poor neighborhoods are more likely to lack one critical institutional resource, the childcare center. Methods. We use geocoded data on all licensed centers in the City of New York, address matched to Census tracts. We estimate logit models of presence of center in tract, testing for the linear and nonlinear effects of tract poverty level after controlling for residential instability, joblessness, ethnic makeup, and other demographic factors. We complement the analysis with documentary, interview, and ethnographic data on centers in one poor and one nonpoor neighborhood in the city. Results. We find (1) that the probability of presence of a childcare center does not decrease as poverty level increases; (2) the relationship depends strongly on funding source, with privately funded centers being less likely and publicly funded ones more likely to be present in poor neighborhoods; and (3) at least two factors affect why poor neighborhoods are more likely to have certain centers, the local state and the (often neglected) nonprofit infrastructure. Conclusions. The findings suggest that poor mothers are not necessarily better off in middle‐class neighborhoods in this respect. The market assumptions underlying the initial hypothesis should be modified. More empirical research on the effect of the nonprofit sector on the prevalence of neighborhood institutions is needed. 相似文献

Social Status as a Predictor of Race and Gender Stereotypes in Late Childhood and Early Adolescence 总被引:2,自引:0,他引:2
Stephanie J. Rowley Beth Kurtz-Costes Rashmita Mistry Laura Feagans 《Social Development》2007,16(1):150-168
We examined race and gender stereotypes in fourth‐, sixth‐ and eighth‐grade White and Black children. The participants reported their perceptions of the competence of Black, White, female and male children in academic domains, sports and music. In general, low‐status groups (girls and Black children) did not endorse stereotypes that reflected negatively on their own group but were likely to report stereotypes that favored their social group. High‐status groups (boys and Whites) endorsed most traditional stereotypes, whether negative or positive, for their social group. Where age differences appeared, older children were more likely than younger children to report traditional stereotypes and status effects were more pronounced. The results are discussed in terms of group enhancement and relationships between social stereotypes and self‐views. 相似文献

Child sexual, physical, and emotional abuse as well as child neglect and domestic violence, community violence, and Childhood Traumatic Grief may result in significant and long-lasting emotional and behavioral difficulties. This article reviews randomized controlled studies that have assessed child mental health outcomes for maltreated and violence-exposed children. Key points of this review include the following: (1) maltreated and violence-exposed children typically experience more than one of these types of traumas; (2) effective psychosocial treatments are available to address Posttraumatic Stress Disorder (PTSD), depression, anxiety, and behavioral problems in these children; (3) it is likely that treatments which effectively reduce mental health symptoms in children exposed to one type of child maltreatment or violence exposure will also be effective for other or multiple types; and (4) mental health outcomes are not the only important outcomes to address in future treatment or intervention efforts. These future directions for treatment intervention research are addressed. 相似文献

This discussion is extracted from a larger research project in which an attempt is made to remedy the conceptual difficulties surrounding the “middle state” in international relations by defining the middle state vis-à-vis other types of states and without reference to any single dominant ontological framework. In this section of that project, the statistical technique of cluster analysis is used to demonstrate that the international state system contains three delineable state groups (labeled great, middle and small states). This article also demonstrates the use and usefulness of the cluster technique in international relations research. 相似文献

Statistical modeling for Bayesian extrapolation of adult clinical trial information in pediatric drug evaluation 下载免费PDF全文
Margaret Gamalo‐Siebers Jasmina Savic Cynthia Basu Xin Zhao Mathangi Gopalakrishnan Aijun Gao Guochen Song Simin Baygani Laura Thompson H. Amy Xia Karen Price Ram Tiwari Bradley P. Carlin 《Pharmaceutical statistics》2017,16(4):232-249
Children represent a large underserved population of “therapeutic orphans,” as an estimated 80% of children are treated off‐label. However, pediatric drug development often faces substantial challenges, including economic, logistical, technical, and ethical barriers, among others. Among many efforts trying to remove these barriers, increased recent attention has been paid to extrapolation; that is, the leveraging of available data from adults or older age groups to draw conclusions for the pediatric population. The Bayesian statistical paradigm is natural in this setting, as it permits the combining (or “borrowing”) of information across disparate sources, such as the adult and pediatric data. In this paper, authored by the pediatric subteam of the Drug Information Association Bayesian Scientific Working Group and Adaptive Design Working Group, we develop, illustrate, and provide suggestions on Bayesian statistical methods that could be used to design improved pediatric development programs that use all available information in the most efficient manner. A variety of relevant Bayesian approaches are described, several of which are illustrated through 2 case studies: extrapolating adult efficacy data to expand the labeling for Remicade to include pediatric ulcerative colitis and extrapolating adult exposure‐response information for antiepileptic drugs to pediatrics. 相似文献

In this paper we explore the use of disclosure as a regulatory tool, using as an illustration the current UK requirements
regarding the disclosure of information about internal control. After discussing the broad concept of regulation by disclosure,
we trace the evolution of concepts of internal control and its reporting, describing the background to the Turnbull guidance
for directors on internal control reporting, the basis of current UK requirements. We then examine recent examples of internal
control disclosures, identifying the range of ways in which they address the disclosure requirements and considering the possible
impact of the disclosure requirements on corporate behaviour and on the audiences for disclosure. We conclude with some reflections
on the disclosure life cycle. The paper contributes to the literature on disclosure by specifically considering the role of
disclosure as a regulatory tool and by examining the nature of specific disclosures in an area of continuing interest, that
of internal control. 相似文献

Indecisive students often present with social skills problems, which may make academic and vocational decision‐making tasks difficult and complex for them. Moreover, choices regarding one's future require the ability to gather information, to search for help and support, to stave off intrusiveness and pressures, and to communicate one's decisions. Social competencies, particularly, play a significant role in vocational guidance activities. This article presents a training program devised to augment assertive competencies in indecisive students choosing a university course of study. Intended aims and the analyses to assess the efficacy of the intervention through self‐evaluation and role‐play assessment are described. 相似文献

Objective. To understand how adaptation/assimilation, disruption, and diffusion interact to produce changes in fertility levels among successive generations of Mexicans and Central Americans in the United States. Method. Using restricted access data that link individual data (CPS) to neighborhood data (census tracts), we examine the role of generation, personal characteristics, and neighborhood characteristics in determining children ever born (CEB). Results. There are significant differences in fertility across generations and, to a lesser extent, between women who live in ethnic enclaves and those who do not. Once personal characteristics are considered, the independent effect of generation on fertility is nearly eliminated. Personal characteristics dominate neighborhood characteristics in their ability to predict fertility. The most consistent predictor of CEB at the neighborhood level is the percentage of Hispanic adults. Conclusions. Personal characteristics dominate fertility change across generation, and were it not for increases in educational attainment, fertility might be higher in successive generations rather than lower or unchanged. 相似文献

Through collaboration with the Toy Industry Foundation, Homes for the Homeless launched the Healthy Living Center project in May 2003. The Healthy Living Center attempts to promote positive youth development in a recreational setting that incorporates informal education. Three primary goals guide the creation and implementation of Healthy Living Center components; first, to expose children to creative, social play, giving them a framework for positive socialization that can often be elusive for homeless children as a result of frequent transitions and instability; next, to give children the opportunity to develop their own talents, skills, and creativity, thus enhancing the child's cognitive skills, as well as his or her self‐concept and sense of self‐worth; and finally, to provide a positive, youth‐centered framework for a child's self‐development. This framework gives children vital tools for long‐term success, giving them practice in forming and maintaining positive social relationships and helping them to fully discover and take advantage of their own personal strengths and potential. 相似文献
