Student engagement is an important contributor to school success, yet high school students routinely describe themselves as disengaged. Identifying factors that alter (increase) engagement is a key aspect of improving support for student achievement. This study investigated students’ perceptions of autonomy, teacher connection, and academic competence as predictors of changes in student engagement within the classroom from the start to the end of a course. Participants were 578 (58% female) diverse (67.8% White, 25.2% African American, 5.1% Hispanic, 1.2% Asian American) high school students from 34 classrooms who provided questionnaire data both at the start and the end of a single course. Novel results from a cross-lagged model demonstrated that students who perceived their classrooms as allowing and encouraging their own autonomy in the first few weeks increased their engagement throughout the course, rather than the typical decline in engagement that was demonstrated by students in other classrooms. This finding is unique in that it extended to both students’ perceptions of engagement and observations of student engagement, suggesting a fairly robust pattern. The pertinence of this finding to adolescent developmental needs and its relationship to educational practice is discussed.  相似文献

Although research consistently suggests that adolescents in single-mother families are at increased risk for depression, the mechanisms that explain this relationship are unclear. In a community sample of adolescents (N?=?368; ages 12–16; 50?% female; 50?% White) and their mothers (42?% single), adolescents completed measures of depressive symptoms, rumination, and depressogenic inferential style at baseline and two yearly follow-ups. Mothers reported on stressful events that occurred in the child’s life from birth until baseline. Adolescents raised by single mothers, relative to partnered mothers, experienced more childhood stressors and higher rumination levels at 1-year follow-up. Additionally, higher rumination mediated the relationship between single motherhood and greater youth depressive symptoms at the 2-year follow-up. Clinical implications and developmental considerations are discussed.  相似文献

In this cross-sectional study of substance users in Norway, the authors describe the patterns of victimization and investigate the factors associated with victimization, for nonoffenders and offenders separately. Recent victimization was reported by 59%, and the victimization rate was higher among offenders compared with nonoffenders (69% and 43%, p < .001). Women, regardless of offender status, experienced more victimization. Unstable housing was associated with victimization among nonoffenders, whereas markers for more severe substance use and indicators for poor mental health were associated with victimization in both groups. Addressing these factors may be important in reducing victimization and its negative outcomes among substance users.  相似文献

The 2030 Agenda for Sustainable Development promotes multi‐stakeholder partnerships (MSPs) as a means of implementation while at the same time putting renewed focus on the need for national‐level ownership and implementation. Despite the fact that an ever growing body of literature on the merits and drawbacks of MSPs delineates several success conditions for partnerships, efforts to translate this knowledge into national‐level meta‐governance for MSPs remain marginal to date. This study outlines the benefits the literature alleges for such “meta‐governance” frameworks, before it uses a country‐level study with a series of stakeholder interviews to take a closer look at national‐level context conditions and lessons learned with regard to two water partnerships in Kenya. Our findings suggest that to date the existing meta‐governance for partnerships in Kenya is rather weak and fragmented. Yet respondents support the view that MSPs could benefit from such a framework, in particular regarding local ownership of MSPs and the potential to scale successful cases.

The Organisation for Security and Co-operation in Europe (OSCE) has rarely been considered in scholarship on gender and security, even though it was one of the regional security organisations whose gender policy predated the United Nations Security Council’s call for more international attention to issues related to women, peace and security in October 2000. Based on an analysis of official OSCE documents and on semi-structured interviews, we trace the integration of gender issues in the OSCE and explore the rationale behind and the challenges associated with it. We identify two phases of gender policy change in the OSCE and show how the integration of UNSCR 1325 brought about an expansion of OSCE gender policy from an exclusive focus on “soft” security issues towards increased inclusion of gender in the area of “hard” security. Drawing on historical and feminist institutionalism, we argue that reform coalitions were crucial for the policy changes in the OSCE but that they encountered institutional and ideational barriers, which hampered implementation of the gender policy. In light of rising opposition, our analysis warns of a backlash that might jeopardise current achievements.  相似文献

Racialization is a constant process of “doing race”. Critical whiteness studies make efforts to address the silencing of whiteness in mainstream white feminism. In this article memory work is explored as a possible method for studies of whiteness as an unmarked majority position. The focus is on methodological practices or “how‐to‐do” questions. Starting from feminist epistemology the author investigates ways of practising the epistemological standpoint of situated knowledges. Feminist epistemology, despite its disagreements, has pointed to the importance of positioning work for scientific knowledge production. The relationship between racialization as an analytical concept and whiteness as dominant majority position is complicated. Usually memory work is employed to address gender or more specifically femininity, but, as argued here, it is well suited to investigations of racialization, too. The analysis shows that silent avoidance of matters associated with whiteness helps keep the majority position in place; whiteness is co‐produced with silence through avoidance in concrete everyday situations. Despite a number of problematic aspects, memory work proved productive in bridging the gap between an epistemological standpoint and the nitty‐gritty work of doing empirical research. It helped clarify racialization as a relational phenomenon and shows how lack of attention to or awareness of race has implications for scientific knowledge production.  相似文献

Epidemics tend to have a debilitating influence on the lives of directly afflicted families. However, the presence of an epidemic can also change the behaviour and outcomes of those not directly affected. This paper makes use of a short, sharp, unexpected epidemic to examine the behavioural response of the public to a sudden shift in the perceived risk to one’s health and mortality. Our analysis finds that unafflicted school students change their behaviour substantially, affecting important life outcomes. In particular, we find that between 1.9 and 4.7 fewer students, out of a typical cohort of 47 pupils, sit their school leaving examination for every additional 10 cases of severe Dengue per 10 000 inhabitants in a municipality. We rule out several possible mechanisms, leaving an increase in the salience of the disease’s risks as a plausible explanation for our findings.  相似文献

Continuity and change in present-day Swedish . Eskilstuna revisited is a study of language change in real time. It replicates an earlier investigation of the social variation of Swedish in the medium-sized town of Eskilstuna using data collected 29 years after the original study. In my article, I focus on the rate of change in relation to gender. I have studied seven morphological and morphophonological variables which are sociolinguistically marked, and according to general linguistic opinion in Sweden, in the process of fairly rapid change towards the standard forms of the written language. Our data show that the rate of change at the level of the community is low. Social and age differences have decreased, whereas gender differences have increased. I discuss different explanations for the fact that women in Eskilstuna use more standard language than men, and attempt to analyse why the men still use so many local variants.  相似文献
