Despite growing interest in EU-level transnational networks, there is little understanding about how these form. This article investigates the formation of one network—the European Coalition for Vision (ECV). Using document analysis of 100 email exchanges, 12 semi-structured interviews, and observation of 5 ECV meetings, it identifies environmental and organizational triggers, most important to the creation of the ECV. Findings show that while environmental triggers played a role in ECV formation, organizational triggers were crucial. In particular, the presence of network leaders, a network entrepreneur and a network mentor were vital for the successful creation of the network.  相似文献

Environmental markets have several institutional features that provide a new context for the use of auctions and that have not been studied previously. This paper reports on laboratory experiments testing three auction forms—uniform and discriminatory price sealed‐bid auctions and an ascending clock auction. We test the ability of subjects to tacitly or explicitly collude in order to maximize profits. Our main result is that the discriminatory and uniform price auctions produce greater revenues than the clock auction, both with and without explicit communication. The clock appears to facilitate successful collusion, both because of its sequential structure and because it allows bidders to focus on one dimension of cooperation (quantity) rather than two (price and quantity).© 2009 by the Association for Public Policy Analysis and Management.  相似文献

An accruing body of evidence supports associations between self-perceived gender typicality and peer relationship difficulties; however, researchers have yet to evaluate peers' perceptions of problem behaviors to gain insight into the social correlates of gender typicality. A short-term longitudinal study was conducted to evaluate associations between gender atypical problem behavior and subsequent peer relational difficulties for 2,076 fifth graders (M age= 10.27; 53% female). Peer nomination methodology was used to assess participants' classroom peer relationships, problem behaviors, and social-emotional characteristics. Findings showed that youth characterized by gender atypical, compared to gender typical, problem behavior (withdrawn boys/aggressive girls vs. withdrawn girls/aggressive boys, respectively) evidenced higher levels of subsequent peer difficulties; moreover, participation in a mutual friendship was associated with decreased risk for peer relationship maladjustment, particularly among youth characterized by gender atypical problem behavior. Results further revealed that, compared to friendless youth, friended youth earned higher prosocial and peer liking scores and, for withdrawn youth, lower emotional sensitivity scores. The present research contributes to our understanding of the potential short-term consequences of youth's gender atypical problem behavior. Findings underscore the need for supplemental conceptualizations of gender typicality as well as multifaceted interventions designed to promote the acceptance of gender nonnormativity, support the development of adaptive peer relationships, and reduce the occurrence of problem behaviors.  相似文献

Suicide is a leading cause of death among adolescents, many of whom fail to disclose suicide concerns to adults who might help. This study examined patterns and predictors of help-seeking behavior among adolescents who seriously considered suicide in the past year. 2,737 students (50.9?% female, 46.9?% male; racial distribution 79.5?% Caucasian, 11.9?% Hispanic/Latino, and 3.6?% Black/African-American) from 12 high schools in rural/underserviced communities were surveyed to assess serious suicide ideation (SI) in the past year, disclosure of SI to adults and peers, attempts to get help, attitudes about help-seeking, perceptions of school engagement, and coping support. Help-seeking was defined as both disclosing SI to an adult and perceiving oneself as seeking help. The relationship between adolescents' help-seeking disclosure and (1) help-seeking attitudes and (2) perceptions of social resources was examined among suicidal help-seeking youth, suicidal non-help-seeking youth, and non-suicidal youth. Of the 381 (14?%) students reporting SI, only 23?% told an adult, 29?% sought adult help, and 15?% did both. Suicidal help-seekers were similar to non-suicidal peers on all measures of help-seeking attitudes and social environment perceptions. Positive attitudes about help-seeking from adults at school, perceptions that adults would respond to suicide concerns, willingness to overcome peer secrecy requests, and greater coping support and engagement with the school were associated with students' increased disclosure of SI and help-seeking. This study supports prevention strategies that change student norms, attitudes and social environments to promote help-seeking among adolescents with SI. Promising intervention targets include increasing students' perceptions of the availability and capability of adults to help them, and strengthening students' understanding of how existing resources can help them cope.  相似文献

This paper explores the influence of central party politics in Auckland local government, in New Zealand’s largest city, following the 2010 amalgamation. Political parties have been an accepted and dominant presence in European representative democratic local government, throughout the 20th century. Not so, however, in New Zealand and Australia, where citizens have ‘flocked to the banner “Keep Politics out of Local Government”. Our analysis of the self-declared party accreditation status of candidates and elected members demonstrates that political affiliation, at least in the main centre Auckland, is on the rise, counter to assumptions that New Zealand local government is largely removed from central politics.  相似文献

The authors examined patterns and correlates of offender specialization versus versatility, or more random offenses, among 206 at-risk men. Both official records and self-report data of offending from late childhood to ages 31–32 years old were used. Aggregate- and individual-level analyses indicated that the predominant offender pattern for this sample was versatility. Three correlates of offender versatility were examined (offense frequency, early onset, gang association). Aggregate-level findings consistently revealed offense frequency as a robust correlate of offender versatility, whereas individual-level findings differed among the three measures of offender versatility. The congruence of these findings with predictions from Patterson’s (1982) coercion model is discussed.  相似文献
