Many agencies actively recruit bilingual social workers. This study presents the reactions of 10 Chinese bilingual social workers to the expectations and demands of their agencies. The study employed a qualitative design with a phenomenological approach. The participants’ responses provide insight into how they manage ethnic and cultural mental health issues in Chinese populations. This study aims to improve social service delivery for clients with limited English proficiency by identifying effective, culturally competent services. The findings suggest that when hiring bilingual social workers, it is just as important for them to be culturally competent as it is for them to be an ethnic or language match with the client base. Having all of these qualities will result in staff members who can provide more effective services by making accurate diagnoses and identifying appropriate treatment plans. In addition to employing bilingual social workers, it is important to maintain good supervision as this will allow supervisees to have a unique perspective on what is involved in providing effective delivery of services to clients with limited English proficiency. Implications for research, practice, and policy are discussed. 相似文献

Stochastic modeling of the geology in petroleum reservoirs has become an important tool in order to investigate flow properties in the reservoir. The stochastic models used contain parameters which must be estimated based on observations and geological knowledge. The amount of data available is however quite limited due to high drilling costs etc., and the lack of data prevents the use of many of the standard data driven approaches to the parameter estimation problem. Modern simulation based methods using Markov chain Monte Carlo simulation, can however be used to do fully Bayesian analysis with respect to parameters in the reservoir model, with the drawback of relatively high computational costs. In this paper, we propose a simple, relatively fast approximate method for fully Bayesian analysis of the parameters. We illustrate the method on both simulated and real data using a two-dimensional marked point model for reservoir characterization. 相似文献

To date, the variant Creutzfeldt‐Jakob disease (vCJD) risk assessments that have been performed have primarily focused on predicting future vCJD cases in the United Kingdom, which underwent a bovine spongiform encephalopathy (BSE) epidemic between 1980 and 1996. Surveillance of potential BSE cases was also used to assess vCJD risk, especially in other BSE‐prevalent EU countries. However, little is known about the vCJD risk for uninfected individuals who accidentally consume BSE‐contaminated meat products in or imported from a country with prevalent BSE. In this article, taking into account the biological mechanism of abnormal prion PrPres aggregation in the brain, the probability of exposure, and the expected amount of ingested infectivity, we establish a stochastic mean exponential growth model of lifetime exposure through dietary intake. Given the findings that BSE agents behave similarly in humans and macaques, we obtained parameter estimates from experimental macaque data. We then estimated the accumulation of abnormal prions to assess lifetime risk of developing clinical signs of vCJD. Based on the observed number of vCJD cases and the estimated number of exposed individuals during the BSE epidemic period from 1980 to 1996 in the United Kingdom, an exposure threshold hypothesis is proposed. Given the age‐specific risk of infection, the hypothesis explains the observations very well from an extreme‐value distribution fitting of the estimated BSE infectivity exposure. The current BSE statistics in the United Kingdom are provided as an example. 相似文献

One of the most established approaches to explain attitudes toward immigration is group conflict theory. However, even though the theory was articulated in dynamic terms, previous research has almost exclusively tested it through cross‐sectional analyses. The aim of this study is to disentangle the dynamic character of ethnic competition from more permanent determinants of ethnic threat. The findings show that a remarkable variation of concern over immigration, usually attributed to permanent positions of economic vulnerability, disappears when within‐person variation is modeled. In line with a dynamic approach of ethnic competition, becoming unemployed or being laid off increases concern over immigration. This effect is independent of social class. 相似文献

Stability and change in kindergartners' friendships were examined based on a typology of profiles (stable, fluid, loss, gain, friendless). Our purpose was to determine whether children belonging to the five profiles differed in their social functioning. The sample was composed of 2353 kindergartners. Reciprocal friendships and social functioning indices were measured using peer nominations collected in October and May of the same year. A series of repeated measures analysis of variance indicated that children in the friendless profile were less accepted by their peers, more shy, more withdrawn, and more aggressive than other children. Moreover, children in the stable profile were significantly more accepted by their peers, more prosocial, and less shy than children in the fluid profile. Lastly, children in the loss profile became less accepted by their peers and less prosocial over the course of the year whereas children in the gain profile became more accepted and prosocial. 相似文献

Risk analysis is challenged in three ways by uncertainty. Our understanding of the world and its uncertainties is evolving; indeterminism is an inherent part of the open universe in which we live; and learning from experience involves untestable assumptions. We discuss several concepts of robustness as tools for responding to these epistemological challenges. The use of models is justified, even though they are known to err. A concept of robustness is illustrated in choosing between a conventional technology and an innovative, promising, but more uncertain technology. We explain that nonprobabilistic robust decisions are sometimes good probabilistic bets. Info‐gap and worst‐case concepts of robustness are compared. Finally, we examine the exploitation of favorable but uncertain opportunities and its relation to robust decision making. 相似文献

In developed countries, rising rates of union disruption have induced an increase in the share of people experiencing several fertile partnerships during their fertile life-span. However, from the large-scale 1999 French Family Survey, in the 1939–1954 birth cohorts it appears that completed fertility of repartnered men is slightly higher than that of never-separated men while repartnered women have fertility levels similar to those who remain in a first intact partnership. Following this observation, this article aims to study whether people, and especially women, have enough time to have children in the context of second union before they become limited by the “biological clock”. Using a cure model, we find that once age-related sterility is controlled for, the decrease in risk of having children with age is not visible anymore up to age 40. This offers some evidence that people in their second partnership, especially women, are constrained in their childbearing by the decline in fecundity with age. Additionally, childless women seem to respond proactively to the decline in fecundity with age by accelerating childbearing. 相似文献

The Effective Provision of Pre‐school Education (EPPE) project is a longitudinal study of young children between the ages of 3 and 7 years. Research began in 1997 and both quantitative and qualitative methods were used to explore the effects of pre‐school education on children’s attainment and social/behavioural development at entry to school, and of any continuing effects on such outcomes at the end of Key Stage 1 (age 7). The sample included over 3,000 children and 141 pre‐school centres drawn from six different types of providers. In addition, a home sample of children who had not attended a pre‐school centre was included. In order to identify the processes that might influence centre effectiveness, observational data were collected and centre managers interviewed. In‐depth case studies of 12 more effective centres were used to explore and illuminate the processes, particularly in relation to pedagogy, associated with better child outcomes. A mixed method approach was adopted to simultaneously answer both confirmatory and exploratory questions, to support user engagement and provide triangulation. The paper argues that the mixed method approach supported the development of stronger research inferences. 相似文献

Professional associations have provided various benefits to their members to bolster member retention and recruitment. This study explored factors that could influence members’ behavioral intentions in professional membership associations by surveying 13,229 members from eighteen associations. More specifically, this analysis focused on the effects of members’ perceptions of the personal and professional benefits offered by associations with which they are affiliated and their satisfaction with those benefits. Our results suggested that members’ perceptions of personal and professional benefits positively correlated with their intentions to renew and recommend membership. If a member perceived a higher level of benefits, he or she would demonstrate a greater likelihood of satisfaction with the benefits and therefore be more likely to renew membership or recommend it to others. This study could advance understanding of the factors that influence members’ behavioral intentions while also providing professional associations with strategies for retaining existing members. 相似文献
