Local governments' allocation decisions are modeled in the context of a slack maximizing bureaucrat who produces public goods according to a production function that includes both provision and the constituents' socio-economic characteristics. To gain a better understanding of the determinants of slack, comparative statics and an empirical study of Illinois municipalities are conducted. The indirect output distance function provides efficiency scores upon which we regress several variables, representing socio-economic characteristics, costs and competition measures. We find that slack or inefficient behavior is associated with richer communities, lower education levels and a lack of competition for residents among municipalities.  相似文献

Educational approaches that enable students to actively and directly participate in “real-world” projects are increasingly recognized as valuable pedagogical tools and, as such, being incorporated into university curriculums worldwide. Though not traditionally associated with political science courses, project-based international service learning presents a tremendous opportunity to bring classroom concepts and theories to life, provide an active approach to addressing international challenges, and assist students in the development of the hands-on, problem-solving, team-based, critical-thinking skills that are increasingly important to employers across all sectors. This article seeks to encourage political science faculty to incorporate international service learning—and/or project-based approaches—into their educational offerings. Through examination of the course Global Synthesis in Liberal Arts and Engineering Studies at California Polytechnic State University, we have identified multiple factors that can help promote successful execution of project-based international service learning as a pedagogical tool, and provide additional suggestions for faculty interested in adopting specific aspects of these educational approaches, and/or in doing so closer to home.  相似文献

Developmental imbalance models attribute the rise in risk-taking during adolescence to a universal imbalance between rising reward sensitivity and lagging cognitive control. This study tested predictions of an alternate Lifespan Wisdom Model that distinguishes between exploratory/adaptive (e.g., sensation seeking) and maladaptive (e.g., acting-without-thinking, delay discounting) risk-taking propensities and attributes the latter to a sub-set of youth with weak cognitive control. Latent trajectory modeling of six waves of data from 387 adolescents (52% females; spanning average ages of 11–18 years) revealed distinct sub-groups with heterogeneous trajectory patterns for acting-without-thinking and delay-discounting. Only those trajectory groups with weak cognitive control, characterized as “high-increasing” acting-without thinking and “high-stable” delay discounting were predictive of a maladaptive risk-taking outcome, namely substance use disorder. Sensation seeking demonstrated a universal peak, but high levels of sensation seeking were not associated with weakness in cognitive control and were unrelated to substance use disorder, controlling for impulsivity. The findings suggest that maladaptive risk-taking characterized by weak cognitive control over reward-driven impulses is a phenomenon limited to only a sub-set of youth.  相似文献

This article focuses on the evolving nature of the foreign policy of the European Union (EU) towards Brazil, which gained momentum and became more dynamic and denser after the establishment of a formal strategic partnership (SP) in 2007. It provides a historical overview of the institutional relations between Brussels and Brasília, before proceeding with an analysis of the main drivers behind this novel development. The study goes on to offer a critical examination of the implementation of the EU–Brazil SP by casting light on both its major achievements and the challenges it has faced. It concludes that the establishment of a formal strategic partnership with Brazil has contributed to the strengthening of the EU’s globally oriented partnership policy and ultimately to the incremental empowerment of the EU necessary to the assertion of its values, objectives and interests on the international stage.  相似文献

The goal of the current study was to examine the protective role that maternal media monitoring might have for adolescents. This was done by considering whether styles of media monitoring either directly reduced media use, or whether they buffered the associations between aggressive media use and adolescents’ prosocial behavior, aggression, and delinquency. Participants were 681 adolescents from two cities in the United States (51% female; 73% white), and their mothers, who provided data at two different time points, 2 years apart (when adolescents were roughly ages 13 and 15). Mixture modeling results revealed that mothers used four different styles of media monitoring made up of combinations of active and restrictive monitoring as well as forms of co-use. Styles that included active monitoring and connective co-use (i.e., engaging in media with the intent to connect with children) were directly associated with less media use, and moderated links between adolescents’ media use and behavioral outcomes concurrently but not longitudinally. The discussion was focused on the strength of considering multiple strategies of media monitoring together, and how this approach can inform future research in the area of parental media monitoring.  相似文献
