There is broad agreement that neighborhood contexts are important for adolescent development, but there is less consensus about their association with adolescent smoking and alcohol use. Few studies have examined associations between neighborhood socioeconomic contexts and smoking and alcohol use while also accounting for differences in family and peer risk factors for substance use. Data drawn from the Seattle Social Development Project (N?=?808), a gender-balanced (female?=?49%), multiethnic, theory-driven longitudinal study originating in Seattle, WA, were used to estimate trajectories of smoking and alcohol use from 5th to 9th grade. Time-varying measures of neighborhood socioeconomic, family, and peer factors were associated with smoking and alcohol use at each wave after accounting for average growth in smoking and alcohol use over time and demographic differences. Results indicated that living in more socioeconomically disadvantaged neighborhoods, lower family income, lower family general functioning, more permissive family smoking environments, and affiliation with deviant peers were independently associated with increased smoking. Lower family functioning, more permissive family alcohol use environments, and deviant peers were independently associated with increased alcohol use. The effect of neighborhood disadvantage on smoking was mediated by family income and deviant peers while the effect of neighborhood disadvantage on alcohol use was mediated by deviant peers alone. Family functioning and family substance use did not mediate associations between neighborhood disadvantage and smoking or alcohol use. The results highlight the importance of neighborhood, family, and peer factors in early adolescent smoking and alcohol use. Future studies should examine the unique association of neighborhood disadvantage with adolescent smoking net of family socioeconomics, functioning, and substance use, as well as peer affiliations. Better understanding of the role of contextual factors in early adolescent smoking and alcohol use can help bolster efforts to prevent both short and long harms from substance use.  相似文献

Scotland’s future within the European Union (EU) played a prominent role in the 2014 independence referendum. The story goes that latent supporters of independence voted to stay within the UK to maintain EU access. Defeated, Scottish leaders declared the referendum a once-in-a-life-time event only repeated if conditions substantially changed. With the UK now facing a chaotic exit from the EU, proponents of Scottish independence have suggested that a second referendum may occur after Brexit negotiations are completed. Faced with a consensus among Scottish party leaders in supporting EU membership, those hoping for a second independence referendum, we argue, looked to alternate sources of information that saw Brexit as an opportunity to create the conditions that would spur a second referendum. Using panel data from the British Election Study, we examine whether Scottish voters voted tactically to leave the EU. We argue that Scottish National Party voters were likely to interpret statements on the conditions for a second independence referendum as an implicit signal to vote “Leave.” The results have important implications for the role of referendums in representative democracy, strategic voting, and the importance of intra-party division on individual vote choices.  相似文献

Since the mid-twentieth century, elite political behavior in the United States has become much more nationalized. In Congress, for example, within-party geographic cleavages have declined, roll-call voting has become more one-dimensional, and Democrats and Republicans have diverged along this main dimension of national partisan conflict. The existing literature finds that citizens have only weakly and belatedly mimicked elite trends. We show, however, that a different picture emerges if we focus not on individual citizens, but on the aggregate characteristics of geographic constituencies. Using biennial estimates of the economic, racial, and social policy liberalism of the average Democrat and Republican in each state over the past six decades, we demonstrate a surprisingly close correspondence between mass and elite trends. Specifically, we find that: (1) ideological divergence between Democrats and Republicans has widened dramatically within each domain, just as it has in Congress; (2) ideological variation across senators’ partisan subconstituencies is now explained almost completely by party rather than state, closely tracking trends in the Senate; and (3) economic, racial, and social liberalism have become highly correlated across partisan subconstituencies, just as they have across members of Congress. Overall, our findings contradict the reigning consensus that polarization in Congress has proceeded much more rapidly and extensively than polarization in the mass public.  相似文献

ABSTRACT

Scholars are increasingly re-theorizing territory beyond the nation-state given Indigenous and Afro-descendant groups’ demands for ‘territory’ as they confront land grabbing in Latin America. Yet alternative territorialities are not limited to such ethnic groups. Based on 16 months of ethnographic research between 2011 and 2016, I explore the relational territoriality produced by a peasant ‘peace community’ in San José de Apartadó, Colombia. By tracing the collective political subject produced by the Peace Community’s active production of peace through a set of spatial practices, places and values, which include massacre commemorations, food sovereignty initiatives and Indigenous–peasant solidarity networks, this contribution presents a conceptual framework for analyzing diverse territorial formations.  相似文献

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

The United States Supreme Court’s recent decision relating to violent video games revealed divisions within the scientific community about the potential for negative effects of such games as well as the need for more, higher quality research. Scholars also have debated the potential for violent games to have positive effects such as on visuospatial cognition or math ability. The current study sought to extend previous literature by using well-validated clinical outcome measures for relevant constructs, which have generally been lacking in past research. Cross-section data on aggression, visuospatial cognition, and math achievement were available for a sample of 333 (51.7 % female) mostly Hispanic youth (mean age = 12.76). Prospective 1-year data on aggression and school GPA were available for 143 (46.2 % female) of those youth. Results from both sets of analysis revealed that exposure to violent game had neither short-term nor long-term predictive influences on either positive or negative outcomes. A developmental analysis of the cross-sectional data revealed that results did not differ across age categories of older children, preadolescents or adolescents. Analysis of effect sizes largely ruled out Type II error as a possible explanation for null results. Suggestions for new directions in the field of video game research are proffered.  相似文献

This study seeks to explain why U.S. local governments utilize environmental sustainability to promote economic development. Economic development and environmental protection need not be competing objectives, but rather, environmental protection can enhance local economic competitiveness. Using data from the ICMA Economic Development Survey, this study tests an empirical model that includes state sustainability initiatives, participation in climate protection networks, and political attitudes toward economic development as predictors of local policy decisions. The findings reinforce a multi-level governance perspective on explaining the balance cities seek to achieve between environmental protection and economic growth.  相似文献
