While researchers have found that African American youth experience higher levels of juvenile justice involvement at every system level (arrest, sentencing, and incarceration) relative to their other ethnic counterparts, few studies have explored how juvenile justice involvement and number of contacts might be correlated with this broad range of problems. A convenience sample of 638 African American adolescents living in predominantly low-income, urban communities participated in a survey related to juvenile justice involvement. Major findings using logistic regression models indicated that adolescents who reported juvenile justice system involvement versus no involvement were 2.3 times as likely to report mental health problems, substance abuse, and delinquent or youth offending behaviors. Additional findings documented that the higher the number of juvenile justice system contacts, the higher the rates of delinquent behaviors, alcohol and marijuana use, sex while high on drugs, and commercial sex. These findings suggest that identifying and targeting youth who have multiple juvenile justice system contacts, especially those in low-resourced communities for early intervention services, may be beneficial. Future research should examine whether peer network norms might mediate the relationships between juvenile justice involvement and youth problem behaviors.  相似文献

This study investigated the effects of job characteristics on turnover intention and the mediating effects of job satisfaction. A survey of 317 Korean care workers currently providing in-home elderly care service in the city of Seoul and its suburbs was conducted. The results of multiple regressions and an analysis of mediating effects indicated that role ambiguity and workload had significant effects on turnover intention. In addition, job satisfaction had a mediating effect on the influence of role ambiguity and workload on turnover intention. Finally, theoretical and practical implications are discussed.  相似文献

In this exploratory study, we examine whether organizational mission statement attributes make a difference to the performance of nonprofit performing arts organizations. We use text analysis to measure two semantic attributes—activity and commonality—of mission statements. We examine whether these attributes are associated with improved performance for the instrumental and expressive functions of nonprofit performing arts organizations. Our findings indicate that the mission statement attribute activity is associated with improved performance for both instrumental and expressive functions. Our analysis of nonfindings for the mission statement attribute commonality suggests that there is a need to develop and use content analysis tools tailored to nonprofit contexts.  相似文献

The systemic impact of adoption suggests the need to explore adoption-specific curricula in baccalaureate and graduate degree programs. Using a convenience sample, the present exploratory study collected data in two phases. Phase one included email requests for adoption syllabi to professional email lists and to identified faculty with adoption research and practice expertise. In phase two, 22 faculty members who responded by emailing syllabi were invited to participate in an online survey. Results only begin to unveil what we know about adoption-specific curricula in higher education. Suggestions for future research are discussed.  相似文献

A growing number of cities and towns are implementing “friendly” initiatives to change the community’s social and physical infrastructure to address the needs of a particular vulnerable segment of their population. Three prominent examples are aging-friendly, child-friendly, and immigrant-friendly initiatives. Although the limited but growing literature describes these initiatives as promising strategies to improve the quality of life of the targeted population, to date there has been little written about the underlying goals, values, and assumptions of these efforts. Using the value-critical approach, this article aims to better understand these aspects of population-friendly initiatives by examining the scholarly and grey literature. Social workers engaged in community and policy practice can play a key role in these efforts and call attention to the ways they may alleviate or exacerbate inequities. Future research is needed to assess the effects of these initiatives on their targeted population as well as other community residents.  相似文献

This paper investigates long-term earnings differentials between African American and white men using data that match respondents in the Survey of Income and Program Participation to 30 years of their longitudinal earnings as recorded by the Social Security Administration. Given changing labor market conditions over three decades, we focus on how racial differentials vary by educational level because the latter has important and persistent effects on labor market outcomes over the course of an entire work career. The results show that the long-term earnings of African American men are more disadvantaged at lower levels of educational attainment. Controlling for demographic characteristics, work disability, and various indicators of educational achievement does not explain the lower long-term earnings of less-educated black men in comparison to less-educated white men. The interaction arises because black men without a high school degree have a larger number of years of zero earnings during their work careers. Other results show that this racial interaction by educational level is not apparent in cross-sectional data which do not provide information on the accumulation of zero earnings over the course of 30 years. We interpret these findings as indicating that compared to either less-educated white men or highly educated black men, the long-term earnings of less-educated African American men are likely to be more negatively affected by the consequences of residential and economic segregation, unemployment, being out of the labor force, activities in the informal economy, incarceration, and poorer health.  相似文献

Birth outcomes influence many aspects of later life health and wellbeing, making healthcare access during pregnancy a policy priority. Low-income mothers often depend on Medicaid, for which eligibility is determined by their income relative to state eligibility thresholds. The prevalence of adverse birth outcomes is known to exhibit cyclical variation, due in part to changes in the composition of women giving birth in response to changing economic conditions. However, cyclical variation in adverse birth outcomes also varies with respect to Medicaid eligibility thresholds. Our analysis uses birth-records data for 2000 through 2013, aggregated into 173,936 county-by-quarter observations and linked to county-level unemployment rates and state-level parental Medicaid thresholds. Using fixed-effects negative binomial models, we examine the role of Medicaid generosity in influencing birth outcomes across business cycles. We test for interactions between Medicaid and unemployment, hypothesizing that the negative effects of recessions are worse where Medicaid thresholds are more restrictive. We find that higher Medicaid generosity dampens the negative effects of recessions on birth outcomes. The extent to which Medicaid interacts with unemployment also varies according to the age and race composition of mothers; in particular, Black mothers are both most affected by unemployment and most responsive to Medicaid generosity. Given current concerns about racial gaps in both infant and maternal mortality, our findings suggest that Medicaid may be an important feature of a strategy to close gaps in the prevalence of adverse birth outcomes across racial groups, especially during bust years.  相似文献

This study examines the association between providing care for grandchildren and the economic status of grandparents, focusing on the employment status. This study asks two questions. First, is providing care for grandchildren related to Korean grandparents’ employment status? Second, are the intensities of providing care for grandchildren related to grandparents’ employment status? In examining these research questions, this study focuses on gender and caregiving intensity. The findings suggest that providing care for grandchildren was associated with Korean grandmothers’ employment status. In addition, there are different relationships between providing care for grandchildren and grandparents’ employment status according to the caregiving intensities.  相似文献

This article explores feminist activism via the hashtag #iamafeminist on Twitter in South Korea. This hashtag became an important platform for feminist identification and activism against misogyny following its start in 2015 as a way to resist prevailing anti-feminist sentiment in Korea. In addition to opposing stigmas regarding identifying as a feminist, #iamafeminist affords an inclusive frame that can promote feminist identification by sharing personal motives for and stories about being a feminist. Although critics dismiss the potential of hashtag activism due to its ephemeral nature, I argue that #iamafeminist—which I call the “mother tag”—was able to persist for three months by continuing to connect with real-time gender issues and by initiating activism against misogyny both online and offline.  相似文献
