The proximate correlates of adolescent victimization are well documented in the literature. The purpose of our research is to examine the more fundamental sources of this outcome. Focusing on two basic social contexts—the family and the residential community—we develop a theoretical model and test it empirically against a multilevel data set on juveniles living in Helsinki. Consistent with our hypothesis, we find that the family context is an important determinant of violent victimization. Much of this effect is mediated by involvement in delinquent lifestyles. We also find support for the assumption that community context matters to the risk of victimization independently of the family context and individual-level risk factors. Our research underscores the need for a multilevel approach in explanations of violent victimization.  相似文献

There are many situations wherein a group of individuals (e.g., voters, experts, sports writers) must produce an ordered list of ‘best’ alternatives selected from a given group of alternatives (e.g., candidates, proposals, sports teams). Two long established mechanisms that have been used for this task are ‘Zermelo’s Ranking Method’ (1929) and ‘Borda’s Voting Scheme’ (1781). The main purpose of this paper is to point out that they are, under certain common circumstances, identical. We then show that Zermelo’s Method can be used in situations that Borda’s Method is not designed to handle.  相似文献

ABSTRACT

Historically Black colleges and universities (HBCUs) have a long-standing history of engaging the African-American community. In most instances, these institutions are located in predominantly African-American communities. This article intends to offer a discussion of a pedagogical approach used at an HBCU, located in a large mid-Atlantic city. The purpose of this macro-assignment was an effort designed to prepare BSW students for macro-practice with communities through participation in service-learning projects that involved community engagement with urban communities. Outcomes reflect that students have a vested interest in working with underserved communities, which exemplifies the School of Social Work’s mission; said mission is to fully prepare urban social work leaders who are committed to the alleviation of human suffering, social justice, and the improvement of the quality of life for diverse urban populations.  相似文献

A growing body of literature demonstrates important negative health effects from racial microaggressions for racial/ethnic minorities. However, at present, the bulk of the literature is focused on the case of black Americans with relatively little attention as to how this may play out for other racial/ethnic groups. Here, we examine the association of health and racial microaggressions in the case of Latinos. Furthermore, we disaggregate Latinos by language preference in order to see how acculturation to the USA may moderate the effect of racial microaggressions on health outcomes for the group. In a statistical analysis of the 2004 Behavioral Risk Factor Surveillance System, we examine the association between stress from racial microaggressions and self-rated health for Latinos of different levels of linguistic acculturation. We find that more acculturated Latinos (measured in terms of language preference) are more likely to experience physical stress from perceived racial microaggressions after accounting for social and demographic factors. Further, this stress is linked to overall poorer self-rated health for the group. However, we find no such association for less acculturated, Spanish-preference Latinos.  相似文献

The monitoring of web servers through statistical frameworks is of utmost important in order to verify possible suspicious anomalies in network traffic or misuse actions that compromise integrity, confidentiality, and availability of information. In this paper, by considering the Plackett copula function, we propose a bivariate beta-autoregressive moving average time-series model for proportion data over time, which is the case for variables present in web server monitoring such as error rates. To illustrate the proposed methodology, we monitor a Brazilian web server's rate of connection synchronization and rejection errors in a web system, with error logging rate in the past 10?min. In essence, the entire methodology may be generalized to any number of time-series of error rates.  相似文献

While discussions of state involvement in migration generally focus on restriction, states are actively involved in the promotion of labour migration through guestworker programmes, among other examples. While these programmes are state-sponsored, they often rely heavily on private actors in order to function. Drawing on the examples of the H-2 visa in the United States and the recruitment of foreign workers to Malaysia, this paper examines the common elements of state direction of migration combined with a focus on temporariness and an outsourcing of recruitment and supervision that are present in both guestworker schemes. In drawing on the geographically, economically, and politically distinct contexts of the U.S. and Malaysia we look to how these schemes contain a mixture of state and private authority which permits an especially potent form of control over the lives of guestworkers that is greater than what either state or private actors could produce individually. Such control raises important questions about the nature of public/private governance within migration more broadly.  相似文献

Assessment is a core element of evidence‐based practice, but thorough formal assessment can place a significant burden on clients. We evaluated the clinical viability of using planned missing data designs to reduce client burden. Data come from an archival dataset with 1342 participants. Although significant differences were found in scores with planned missing data versus real scores, the effect sizes for the differences were generally small. Scores with missing data had sensitivity and specificity scores generally above .90 when predicting real scores over clinical cutoffs and improvement in real scores. These findings offer useful information to agencies and researchers looking for ways to collect more data without losing its immediate clinical utility.  相似文献

Poverty measurement and the analysis of the progress (or otherwise) of the poor, whether it is societies, families or individuals, is beset with difficulties and controversies surrounding the definition of a poverty line or frontier. Here, borrowing ideas from the mixture model literature, a new approach to assigning poverty-non poverty status is proposed which avoids specifying a frontier, the price is that an agent’s poverty status is only determined to the extent of its chance of being poor. Invoking variants of Gibrat’s law to give structure to the distribution of outcomes for homogeneous subgroups of a population within the context of a finite mixture model of societal outcomes facilitates calculation of an agent’s poverty status probability. From this it is straightforward to calculate all the usual poverty measures as well as other characteristics of the poor and non poor subgroups in a society. These ideas are exemplified in a study of 47 countries in Africa over the recent quarter century which reveals among other things a growing poverty rate and a growing disparity between poor and non poor groups not identified by conventional methods.  相似文献
