The magnitude of climate change threats to life on the planet is not matched by the level of current mitigation strategies. To contribute to our understanding of inaction in the face of climate change, the reported study draws upon the pro status quo motivations encapsulated within System Justification Theory. In an online questionnaire study, participants (N = 136) initially completed a measure of General System Justification. Participants in a “System-critical” condition were then exposed to information linking environmental problems to the current economic system; participants in a Control condition were exposed to information unrelated to either environmental problems or the economic system. A measure of Economic System Justification was subsequently administered. Regressions of Economic System Justification revealed interactions between General System Justification and Information Type: higher general system justifiers in the System-critical condition rated the economic system as less fair than did their counterparts in the Control condition. However, they also indicated inequality as more natural than did their counterparts in the Control condition. The groups did not differ in terms of beliefs about the economic system being open to change. The results are discussed in terms of how reassurance about the maintenance of the status quo may be bolstered by recourse to beliefs in a natural order. 相似文献

The authors examined the hypothesis that impairments in attention and verbal intelligence are associated with seriously maladaptive social behavior in behavior-disordered, hospitalized adolescents. Twenty-five unmedicated inpatients with disruptive behavior disorder diagnoses were rated during a one-month period for frequency of severe disruptive episodes, or critical incidents (CI); these included assaults, behavior resulting in the use of restraints, etc. All subjects independently received intelligence testing and continuous performance testing (CPT). Based on CI scores, subjects were divided into a high-CI group (CI>5; N=9) and a low-CI group (CI<4; N=16). On the CPT, the high-CI group showed more impairment in perceptual sensitivity (d; this group also had lower verbal IQ scores. (Both findings were significant at the p<.05 level.) The latter result was largely due to differences in Comprehension subtest scores. These results support the hypothesis, and may have implications for the treatment of behavior-disordered adolescents.Received M.D. from the University of Wisconsin, Major research interests are adolescent psychopathology, disruptive behavior disorders, and information processing.Received Ph.D. from the University of Wisconsin.

This paper analyzes the possible effects of a customs union between Ukraine and the European Union. The GTAP multi-country
simulation model of Purdue University’s Center for Global Trade Analysis is applied. The welfare measure evaluated is the
change in equivalent variation (EV). As all incomes in the model accrue to a representative household, EV fully assesses possible
welfare benefits for Ukraine from bilateral tariff elimination on trade with the EU. As the model includes Ukraine in the
aggregated “Former Soviet Union” region (FSU), EV is estimated for the FSU and then disaggregated on the industry level proportionally
to trade shares. The results of our simulations suggest that Ukraine’s EV is particularly sensitive to the inclusion of the
agricultural sector into a customs union. Due to the highly protected nature of this sector within the EU, Ukraine would be
better off if agriculture were excluded from liberalization. If this scenario is assumed, Ukraine’s monetary gain would be
in the order of $40 million.

This article critically examines a poorly understood aspect of the European security landscape: early warning systems (EWSs). EWSs are socio-technical systems designed to detect, analyse, and disseminate knowledge on potential security issues in a wide variety of sectors. We first present an empirical overview of more than 80 EWS in the European Union. We then draw on debates in Critical Security Studies to help us make sense of the role of such systems, tapping into conceptual debates on the construction of security issues as either “threat” or “risk” related. Finally, we study one EWS – the Early Warning and Response System for infectious diseases – to understand how it works and how it reconciles risk – versus threat-based security logics. Contrary to assumptions of a clear distinction between risk- and threat-based logics of security, we show that EWSs may serve as a “transmission belt” for the movement of issues from risk into threats. 相似文献

ABSTRACTVoting Advice Applications (VAAs) – also known as Voting Engagement Applications – are online tools which inform users about their proximity to party positions before elections by indicating which parties are closest to the policy preferences of the individual voters. Referring to the theory of cognitive dissonance, this article examines the impact of using a VAA on voting behaviour by looking at the effect mechanisms. For the empirical analyses, we draw on data of a two-wave panel study we conducted before the European Elections 2014, thereby focusing on the German VAA – the Wahl-O-Mat. The findings show that irritation emerges if the preferred party is not positioned at the top of the VAA result list. In turn, a strong irritation can lead to a change in vote choice. 相似文献
