ABSTRACT This article presents a typology of international social work research and analyzes trends over a 10-year period (1995–2004) based on reviews of 707 articles from three major American social work research journals: Social Work Research, Journal of Social Service Research, and Research on Social Work Practice. The analysis revealed there was a considerable increase (3.5%) in the total amount of research articles, particularly a higher increase in international social work research (2.8%) than national social work research (0.8%). A small decline was detected in transnational comparative research (?0.4%). 相似文献

This study examines how student perceptions of teacher practices contribute to female high school students’ math beliefs and achievement. Guided by the expectancy–value framework, we hypothesized that students’ motivation beliefs and achievement outcomes in mathematics are fostered by teachers’ emphasis on the relevance of mathematics and constrained by gender‐based differential treatment. To examine these questions, structural equation modeling was applied to a longitudinal panel of 518 female students from the Maryland Adolescent Development in Context Study. While controlling for prior achievement and race, gendered differential treatment was negatively associated with math beliefs and achievement, whereas relevant math instruction was positively associated with these outcomes. These findings suggest inroads that may foster positive math motivational beliefs and achievement among young women. 相似文献

Children's behavioral difficulties are a major source of parental concern. The goals of the current study were to (1) describe preschool-age adopted Chinese girls’ behaviors that were most concerning to their adoptive mothers and (2) examine the relation between children's concerning behaviors and parent/child demographics. Qualitative data from 422 mothers on 480 adopted Chinese girls (M = 44.2 months, SD = 15.2) were collected using three sequenced methods (i.e., open-ended question, follow-ups, and a focus group discussion). These girls were adopted at 3 to 60 months of age (M = 13.8, SD = 8.0) and had lived in the adoptive homes for at least 6 months (M = 30.2, SD = 14.4). Data analysis showed that 242 (57.3%) mothers (representing 274 girls) reported one to three concerning behaviors per child (total = 323 concerns), including behaviors that indicated attachment problems (107 or 33.1%), poor social skills (46 or 14.2%), language/speech problems (42 or 13%), sleep problems (29 or 9%), health/physical problems (24 or 7.4%), and problems in other areas (e.g., potty training) (75 or 23.2%). Further analysis showed that the mothers with prior experience of raising adopted children, but not biological children, were more likely to report concerning attachment behaviors than first-time mothers. 相似文献

This is a review of the issues and debate over capital punishment in the United States during the post- Furman era (since 1972). It encompasses a review of the legal issues, highlighting major U.S. Supreme Court cases in which the constitutionality of the death penalty has been challenged. These constitutional challenges have included issues of arbitrariness and race discrimination in the application of the death penalty. Also considered is the Court's 'evolving standards of decency' test in terms of what constitutes cruel and unusual punishment under the Eighth Amendment – relative to the execution of juveniles and the mentally retarded and whether lethal injection is cruel and unusual. The post- Furman era death penalty debate is comprised of two phases, both raised questions about public confidence in the criminal justice system. Phase one, occurring in the 1980s and early 1990s, was concerned with the lengthy appeal process and the lack of finality in capital cases. Phase two emerged in the late 1990s and 2000s and focused on the accuracy (wrongful convictions) and fairness (arbitrariness and discrimination) of the administration of capital punishment. The DNA revolution and a parade of high-profile exonerations in the United States contributed to this latter phase. Finally, the death penalty debate is considered from an international and human rights perspective. 相似文献

There are various situations in which it may be important to obtain expert opinion about some unknown quantity or quantities. But it is not enough simply to ask the expert for an estimate of the unknown quantity: we also need to know how far from that estimate the true value might be. Tony O'Hagan describes the process of elicitation: the formulation of the expert's knowledge in the form of a probability distribution. 相似文献

Although heterogeneity across individuals may be reduced when a two-state process is extended into a multi-state process, the discrepancy between the observed and the predicted for some states may still exist owing to two possibilities, unobserved mixture distribution in the initial state and the effect of measured covariates on subsequent multi-state disease progression. In the present study, we developed a mixture Markov exponential regression model to take account of the above-mentioned heterogeneity across individuals (subject-to-subject variability) with a systematic model selection based on the likelihood ratio test. The model was successfully demonstrated by an empirical example on surveillance of patients with small hepatocellular carcinoma treated by non-surgical methods. The estimated results suggested that the model with the incorporation of unobserved mixture distribution behaves better than the one without. Complete and partial effects regarding risk factors on different subsequent multi-state transitions were identified using a homogeneous Markov model. The combination of both initial mixture distribution and homogeneous Markov exponential regression model makes a significant contribution to reducing heterogeneity across individuals and over time for disease progression. 相似文献
