Past research suggests that beliefs and emotions operate as partially distinct determinants of political attitudes. In addition, while positive and negative beliefs about a political object are bipolar in structure, positive and negative emotions have been demonstrated to be relatively independent. In this past research, beliefs and emotions have been assessed with different measures. Yet current models of survey responding suggest that responses to survey items are often influenced by the manner in which the researcher poses the questions. As such, it is not clear whether the uniqueness of these belief and emotion measures reflects a bona fide difference between two underlying constructs, or merely an artifactual difference induced by differing methods of measurement. In this study, beliefs and emotions are shown to operate as partially unique predictors of candidate evaluation even when employing corresponding methods of measurement. The independence of positive and negative emotion, however, only arises when employing a dichotomous measure. When employing ordinal measures, positive and negative emotions contain a substantial component of bipolarity. The theoretical implications of these findings are discussed. 相似文献

China's rapidly growing motor vehicle fleet is changing the makeup of its urban atmosphere. While the two major problem pollutants historically have been particulates and sulfur dioxide, the growth in the number of automobiles has generated substantially increased levels of nitrogen dioxide (NO2). This paper examines and values the mortality health effects (reduced premature deaths) from cleaning up these three pollutants. Findings indicate that valued gains from reduced air pollution mortality can average 3% of a city's GDP. Moreover, the growing auto fleet may generate a ten-fold increase in NO2-based mortality costs and offset other, ongoing cleanup efforts in many Chinese cities. Specifically, the paper explores how the increasing number of automobiles might diminish or offset environmental cleanup activities focused upon particulate and sulfur dioxide pollution. 相似文献

This paper describes an effort to develop a clinical tool for the continuous monitoring of risk for violence in forensic mental health clients who have left their institutions and who are dwelling in the community on a conditional release basis. The model is called Structured Outcome Assessment and Community Risk Monitoring (SORM). The SORM consists of 30 dynamic factors and each factor in SORM is assessed in two ways: The current absence, presence or partial och intermittent presence of the factors, which is an actuarial (systematized and 'objective') assessment. Secondly, the risk effect, i.e. whether the presence/absence of factors currently increases, decreases or is perceived as unrelated to violence risk, is a clinical (or impressionistic) assessment. Thus, the factors considered via the SORM can be coded as risk factors or protective factors (or as factors unimportant to risk of violence) depending on circumstances that apply in the individual case. Further, the SORM has a built-in module for gathering idiographical information about risk-affecting contextual factors. The use of the SORM and its potential as a risk monitoring instrument is illustrated via preliminary data and case vignettes from an ongoing multicenter project. In this research project, patients leaving any of the 9 participating forensic hospitals in Sweden is assessed at release on a variety of static background factors, and the SORM is then administered every 30 days for 2 years. 相似文献

Sudan is one of the countries that is currently in the processof negotiating its accession to the World Trade Organization.This article gives an overview of the legal implications ofWTO accession for Sudan, detailing the expected changes andtheir implementation costs in terms of institutional and legalreform. While not exhaustive, it discusses some of the agreementsthat may pose particular implementation challenges, and suggeststhat Sudan should forge links with least developed countries(LDCs) and other WTO members and seek support during the negotiations.The successful conclusion of negotiations and the accessionof Nepal and Cambodia, both LDCs, at the fifth WTO MinisterialConference in September 2003 should provide a positive impetusand lessons for others such as Sudan that are in the processof accession. 相似文献
