From 9/11 in the U.S. to train, subway, and airport bombings elsewhere, individuals frequently must make political decisions in the shadow of terrorist attacks. To date, few studies have examined how times of terror threat influence voters’ decision-making processes. Using data generated from three experiments we show that, in times of terrorist threat (compared to good times), individuals weight leadership more heavily in the voting booth. Our results also shed light on how much weight is given to other determinants of the vote (issues and partisanship) across these two conditions.  相似文献

Does public policy respond to public opinion? Previous research suggests dynamic representation occurs in the aggregate. Yet, most of the evidence for policy response is limited to the policy intentions of elected officials on issues related to more or less government spending. We examine policy response to an alternative dimension of public mood, public preferences for more or less punitive criminal justice policies, using multiple indicators of policy from various stages of the policy-making process. Criminal justice policy should be responsive to public preferences given the public’s concern about crime and the negative social construction of criminals. Thus, there is an electoral incentive for public officials to respond to public preferences along this alternative dimension of public sentiment regarding criminal justice policy. We estimate a DYMIMIC model of federal criminal justice policy as a function of the multiple dimensions of public policy mood using Kalman filtering. The results indicate that criminal justice policy responds to the second, not the first, dimension of public mood. We find evidence that policy-makers at multiple stages of the policy process are able to differentiate among multiple signals from the public and respond appropriately. The results present a more sophisticated portrait of democratic responsiveness.  相似文献

What participation mechanisms connect citizens and city officials? Do they produce valued outcomes? Surveys of elected officials suggest that microlevel mechanisms such as direct citizen contact are more valuable in meeting participation goals than are mechanisms focusing on macrolevel concerns. However, there is a disconnect between perceptions about value and the use of mechanisms. State‐level participation requirements and a city manager have little effect on the value of a mechanism. These findings raise some questions: why are microlevel participation mechanisms favored, why do some mechanisms have value even though respondents have little experience with them, and why is there a misalignment between participatory goals and the mechanisms used?  相似文献

There is growing interest in the application of citizen participation within all areas of public sector service development, where it is increasingly promoted as a significant strand of post-neoliberal policy concerned with re-imagining citizenship and more participatory forms of citizen/consumer engagement. The application of such a perspective within health services, via co-production, has both beneficial, but also problematic implications for the organisation of such services, for professional practice and education. Given the disappointing results in increasing consumer involvement in health services via 'choice' and 'voice' participation strategies, the question of how the more challenging approach of co-production will fare needs to be addressed. The article discusses the possibilities and challenges of system-wide co-production for health. It identifies the discourse and practice contours of co-production, differentiating co-production from other health consumer-led approaches. Finally, it identifies issues critically related to the successful implementation of co-production where additional theorisation and research are required.  相似文献

Adolescent networks include parents, friends, and romantic partners, but research on the social learning mechanisms related to delinquency has not typically examined the characteristics of all three domains simultaneously. Analyses draw on data from the Toledo Adolescent Relationships Study (n = 957), and our analytic sample contains 51% male and 49% female as well as 69% white, 24% African-American, and 7% Latino respondents. Parents,’ peers,’ and partners’ deviance are each related to respondents’ delinquency, and affiliation with a greater number of deviant networks is associated with higher self-reported involvement. Analyses that consider enmeshment type indicate that those with both above average romantic partner and friend delinquency report especially high levels of self-reported involvement. In all comparisons, adolescents with deviant romantic partners are more delinquent than those youths with more prosocial partners, regardless of friends’ and parents’ behavior. Findings highlight the importance of capturing the adolescent’s entire network of affiliations, rather than viewing these in isolation, and suggest the need for additional research on romantic partner influences on delinquent behavior and other adolescent outcomes.

This study examined (a) the associations between school connectedness and early adolescent adjustment problems over a 1 year period and (b) the equivalence of these associations across gender. Five hundred middle school students (53.4% female), initially in the 6th and 7th grades, participated in the two-wave study. Results from two-group cross-lagged panel analyses were consistent across boys’ and girls’ data. After controlling for baseline levels of adjustment problems, school connectedness predicted lower levels of early adolescent conduct problems 1 year later. Regarding the opposite direction of associations, and even after baseline levels of school connectedness were taken into account, conduct problems predicted lower levels of subsequent school connectedness. There were no cross-lagged associations between depressive symptoms and school connectedness, although elevated levels of baseline depressive symptoms predicted higher levels of subsequent conduct problems. Findings elaborate previous research by demonstrating that early adolescents actively shape the middle school environment.

Physiologic reactivity to racially rejecting images was assessed in 35 young adults (10 males, 25 female) from African-American backgrounds using the startle probe paradigm. In a laboratory setting, participants viewed 16 images depicting racial rejection, racial acceptance, nonracial negative, and nonracial positive themes. While viewing these images, startling bursts of noise were presented and the magnitude of the eyeblink responses were measured. Results supported an attentional mechanism which suggests that, while viewing both racially rejecting and nonracial positive images, individuals may be so absorbed in processing the images that they appear less distracted by the startling noise. However, these patterns were only found for participants low in racial regard. Young adults who felt positively about their racial background did not exhibit differential processing of startle stimuli as a function of slide themes. Race-rejection sensitivity did not moderate startle reactivity. Developmental implications, particularly in light of coping with racial discrimination, are discussed.

Considerable research has focused on the reliability and validity of informant reports of family behavior, especially maternal reports of adolescent problem behavior. None of these studies, however, has based their orientation on a theoretical model of interpersonal perception. In this study we used the social relations model (SRM) to examine family members’ reports of each others’ externalizing and internalizing problem behavior. Two parents and two adolescents in 69 families rated each others’ behavior within a round-robin design. SRM analysis showed that within-family perceptions of externalizing and internalizing behaviors are consistently due to three sources of variance; perceiver, target, and family effects. A family/contextual effect on informant reports of problem behavior has not been previously reported.  相似文献

Youth with same-sex desire undergo a process of narrative engagement as they construct configurations of identity that provide meaning and coherence with available sexual taxonomies. This article presents a theoretical analysis and four case studies centering on the relationship among context, desire, and identity for youth with same-sex desire. Through an interpretive, holistic analysis of the personal narratives of youth, we examine the integration of same-sex desire, behavior, and identity in the general life story and the selective appropriation of elements of “master narratives” of sexual identity development. Narratives were characterized by challenges to integrate desire, behavior, and identity into a configuration that conformed to the received sexual taxonomy. Implications for theory and further research on sexual identity development are discussed.  相似文献

Links between schools’ demographic composition and students’ achievement have been a major policy interest for decades. Using a racially/ethnically diverse sample from the National Longitudinal Study of Adolescent Health (N = 6,302; 54 % females; 53 % White, 21 % African American, 15 % Latino, 8 % Asian American, 2 % other race/ethnicity), we examined the associations between demographic marginalization, students’ later social integration (loneliness at school, school attachment), and educational performance and attainment. Adolescents who were socioeconomically marginalized at school [i.e., having <15 % same-socioeconomic status (SES) peers] had lower cumulative grade point averages across high school and lower educational attainment. A similar disadvantage was observed among students who were both socioeconomically and racially/ethnically marginalized at school (i.e., having <15 % same-SES peers and <15 % same-racial/ethnic peers). Indirect effects were also observed, such that demographic marginalization was linked to poorer school attachment, and poorer school attachment, in turn, was related to poorer academic performance. These results highlight the educational barriers associated with demographic marginalization and suggest potential targets for future intervention efforts.  相似文献
