BackgroundMaltreated youth are at an elevated risk for the development of problem behaviors. Coping with the death of a family member or close friend during adolescence, referred to as bereavement, is a stressful event that could potentiate risk linked to maltreatment. However, developmental research suggests that youth adjustment is a product of multiple risk and protective factors. Although maltreated youth who experience loss may be particularly vulnerable to behavior problems, personal and contextual factors may attenuate or exacerbate youths’ risk for internalizing and externalizing psychopathology.ObjectiveThe overarching goal of this study is to examine individual, family, and community-level protective factors for maltreated youth who experience bereavement. Specifically, we aim to examine the effect of age 12 bereavement on age 16 internalizing and externalizing psychopathology, and to investigate the moderating role of multi-level protective factors at ages 14 and 16.MethodsThe study consisted of a sample of 800 youth (52.4% female, 45.1% African-American) drawn from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN), collected from 1998 to 2011.ResultsMaltreated youth who experienced significant loss were at increased risk for externalizing symptoms, compared to non-bereaved maltreated youth (β = 0.085, p < .05). Individual future orientation (β = 0.103, p < .05) family future orientation (β = −0.120, p < .05), parental monitoring (β = −0.123, p< .01), and neighborhood collective efficacy (β = −0.126, p < .01) each significantly moderated the association between bereavement and externalizing symptoms.ConclusionsThese results have implications for future interventions aimed towards reducing problem behaviors in adolescents with a history of child maltreatment and who experience bereavement. 相似文献

主体性视角下的网络空间关系是主体虚拟实践所构建的,虚构性是其本质特征。在从现实到虚拟转换过程中,主体的非理性冲破了理性的束缚,主导了主体的行为,造成了网络信息活动的失范。从主体性角度来看,防范网络信息活动失范,应从增加制度供给和强化主体理性着手,通过引导主体在网络实践过程中培养其网络理性,以人的理性规范和引导非理性因素以达到目的。 相似文献

The Concept of Record in Interactive, Experiential and Dynamic Environments: the View of InterPARES*
This article presents the concept of electronic record as articulated by the first phase of the InterPARES (International research on Permanent Authentic Records in Electronic Systems) Project (1999–2001) and discusses it in light of the findings of the second phase of the Project (2002–2006). While InterPARES 1 focused on records produced and/or maintained in databases and document management systems, InterPARES 2 examined records produced and/or maintained in interactive, experiential and dynamic environments. The authors describe the characteristics of these environments and of the entities found in them in the course of case studies conducted on systems used for carrying out artistic, scientific and e-government activities, and propose the new concept of record that InterPARES 2 is eleborating, which expands on that formulated by InterPARES 1.The authors would like to thank InterPARES 2 research assistant Randy Preston for his careful editing and constructive criticisms. Some of his suggestions have been incorporated in the text of this article. 相似文献

The information-seeking behavior of social science graduate students has been the subject of many studies, but none have concentrated only on the economics graduate student population and their unique needs. The purpose of this focus group study was to use group discussions to understand the actual online behavior of graduate economics students when conducting research. The results provide insight and information about the skills and characteristics of economics graduate students, their first steps in conducting research online, their use of publicly available and library resources, challenges to finding information, and resources used to overcome these challenges. 相似文献
