This article examines how child welfare workers from three countries assess risk to a child in the context of different risk assessment tools, child welfare systems and welfare regimes. Previous research suggests that there are distinct differences between child protection-oriented child welfare systems such as England and the U.S., and family service-oriented child welfare systems such as Norway (Gilbert et al., 2011). We use a case vignette method to analyze how 299 child welfare workers from England, Norway and California (U.S.) assess risk. The case vignette describes the case of ‘Beatrice’, a nine year-old girl of Black African descent who was born with an organic heart disease and a cleft palate. We found that respondents from California assessed the risk to be the lowest, followed by respondents from England and Norway. The risk factors that respondents highlighted as important for their assessment also varied significantly between countries, displaying different perceptions of elements in a case constituting risk. Respondents from Norway, who, comparatively, practice within the context of the least regulated assessment platform, identified the most homogenous assessments and types of reasoning, whereas both the assessment of risk levels and identifications of risk factors were more heterogeneous among workers in England and California. We argue that the different risk assessment tools only partly influence what workers identify as risk factors in a case, and that type of welfare states and child welfare systems is also an influence. This study thus supports existing scholarship on the distinctions between child welfare systems. However, we also found significant differences in perceptions of risk factors between England and the United States.  相似文献

Recent work has shown that young children can use fine phonetic detail during the recognition of isolated and sentence‐final words from early in lexical development. The present study investigates 24‐month‐olds' word recognition in sentence‐medial position in two experiments using an Intermodal Preferential Looking paradigm. In Experiment 1, French toddlers detect word‐final voicing mispronunciations (e.g., bu z [by z ] for bu s [by s ] “bus”), and they compensate for native voicing assimilations (e.g., bu z d evant toi [bu zd ?vɑ?twa] “bus in front of you”) in the middle of sentences. Similarly, English toddlers detect word‐final voicing mispronunciations (e.g., shee b for shee p ) in Experiment 2, but they do not compensate for illicit voicing assimilations (e.g., shee b th ere). Thus, French and English 24‐month‐olds can take into account fine phonetic detail even if words are presented in the middle of sentences, and French toddlers show language‐specific compensation abilities for pronunciation variation caused by native voicing assimilation.  相似文献

Feminist approaches to therapy with adolescents emphasize an empowering focus on the strengths of adolescents while simultaneously insisting that therapists become aware of their own biases toward today's adolescents. However, a review of the family therapy literature finds little mention of feminist approaches for addressing injustices (e.g., family scapegoating, negative societal views of adolescents, and gender oppression) that arise in family therapy with adolescents. Therefore, this study explores clinical approaches and resources suggested by a surveyed group of self-identified feminist family therapists. In addition, we also recommend several approaches and resources that will aid family therapists in creating a more just climate for family therapy with youth.  相似文献

The authors' objectives in this study were to describe the proportion of schools providing and the percentage of students with access to HIV and sexually transmitted disease (STD) education, treatment, and prevention services at 2-year and 4-year US colleges and universities. The authors mailed self-administered questionnaires to a stratified random sample (n = 910) of the 2,755 US schools with an enrollment of more than 500 students; 736 (81%) returned the survey. Four hundred seventy-four schools (60%) had a health center, representing 73% of students. Schools with a health center or housing for students were more likely to provide STD education; 52% of the schools made condoms available to students. Sixty percent of schools with health centers could test for both Chlamydia trachomatis and Neisseria gonorrhoeae, but only 67% of these schools screened women for these infections. Although most schools provided some prevention education, access to prevention, testing, and education should be increased at schools where these services are possible but not available.  相似文献

Discrimination is long seen as a meaningful factor for ethnic inequalities on rental housing markets. Yet empirically, the extent of discrimination is still debatable. For the first time, this article provides a quantitative meta-analysis of field experiments (in person audits and correspondence tests) that were run over the last four decades in the United States, Canada and Europe (N?=?71). Special focus is given to a possible inflation of effect sizes by publication bias; to time trends; and to evidence for statistical discrimination. Taken together, nearly all experiments document the occurrence of ethnic discrimination. Effect sizes are inflated by publication bias, but there is still substantial evidence left once the bias is removed. The analysis reveals a consistent decline in the extent of discrimination over time, from moderate levels of discrimination in the 1970s and 1980s, up to only small but still statistically significant levels in the 1990s and 2000s. A significant part of the discriminatory behaviour can be attributed to missing information about the social status of applicants, which supports theories on statistical discrimination. It is discussed how future research could move our knowledge on the underlying mechanisms forward.  相似文献

In this article, we examined fathers who were or had been in contact with the Child Welfare Services in Norway. All of the fathers included in this study had children with women who were unable to take care of them, either because of substance abuse or mental health problems. Hence, the fathers had the primary responsibility for the children. We looked at how these fathers experienced being met and assessed as caregivers by the Child Welfare Service, as well as how they experienced their own competency as caregivers. To explore these themes, seven fathers who were in contact with or had recently been in contact with the Child Welfare Service were interviewed. The discourses on fatherhood, inspired by Scourfield (2003), were used as a framework for the analysis, and interpretive phenomenological analysis (IPA) was used to analyse the interviews. We found the fathers' experiences to be considered within the discourses on “fathers as a threat”, “fathers as irrelevant” and “fathers as better than mothers”. In addition, we shed light on topics such as the cultural lag, being single-handedly responsible for the children, and the fathers' views on what is important in their contact with the children.Our goal was to increase awareness about fathers who are in contact with the Child Welfare Service so that they are met in a way that helps to support them in their role as fathers for the benefit of their children.  相似文献

Drawing on in-depth, semi-structured interviews with a sample of 24 child protection workers in the northeastern United States, we analyze how workers engage with non-citizen immigrant families. Confirming findings from previous scholarship on immigrants' fears when interacting with Child Protection Services (CPS), workers reported encountering different fear factors—the organizations, events, or people that instill fear in immigrant families. These included fear of deportation, fear of CPS workers as the people who remove children, and fear of CPS as a potentially repressive government agency. We also found that workers seek to minimize or leverage these fears in the engagement process—we refer to this process as fear management. Most of the workers interviewed seek to minimize immigrant families' fears, and we show that they employ four strategies to do so: providing knowledge, brokering services, doing dignity and status work, and learning culture.  相似文献

In meta-analyses of rare events, it can be challenging to obtain a reliable estimate of the pooled effect, in particular when the meta-analysis is based on a small number of studies. Recent simulation studies have shown that the beta-binomial model is a promising candidate in this situation, but have thus far only investigated its performance in a frequentist framework. In this study, we aim to make the beta-binomial model for meta-analysis of rare events amenable to Bayesian inference by proposing prior distributions for the effect parameter and investigating the models' robustness to different specifications of priors for the scale parameter. To evaluate the performance of Bayesian beta-binomial models with different priors, we conducted a simulation study with two different data generating models in which we varied the size of the pooled effect, the degree of heterogeneity, the baseline probability, and the sample size. Our results show that while some caution must be exercised when using the Bayesian beta-binomial in meta-analyses with extremely sparse data, the use of a weakly informative prior for the effect parameter is beneficial in terms of mean bias, mean squared error, and coverage. For the scale parameter, half-normal and exponential distributions are identified as candidate priors in meta-analysis of rare events using the Bayesian beta-binomial model.  相似文献

The analysis of adverse events (AEs) is a key component in the assessment of a drug's safety profile. Inappropriate analysis methods may result in misleading conclusions about a therapy's safety and consequently its benefit‐risk ratio. The statistical analysis of AEs is complicated by the fact that the follow‐up times can vary between the patients included in a clinical trial. This paper takes as its focus the analysis of AE data in the presence of varying follow‐up times within the benefit assessment of therapeutic interventions. Instead of approaching this issue directly and solely from an analysis point of view, we first discuss what should be estimated in the context of safety data, leading to the concept of estimands. Although the current discussion on estimands is mainly related to efficacy evaluation, the concept is applicable to safety endpoints as well. Within the framework of estimands, we present statistical methods for analysing AEs with the focus being on the time to the occurrence of the first AE of a specific type. We give recommendations which estimators should be used for the estimands described. Furthermore, we state practical implications of the analysis of AEs in clinical trials and give an overview of examples across different indications. We also provide a review of current practices of health technology assessment (HTA) agencies with respect to the evaluation of safety data. Finally, we describe problems with meta‐analyses of AE data and sketch possible solutions.  相似文献
