This article reports the results of a study that replicates and extends the impression-driven model of candidate evaluation reported in Lodge, McGraw, and Stroh (1989). This model holds that evaluations are formed and updated on-line as information is encountered, and that as a result, citizens need not rely on specific information available from memory to form their candidate evaluations. In the present work we explore whether the order in which information is encountered, as well as whether information that is personally important, influences the weight accorded to evidence in on-line processing. In addition, differences in information-processing strategies due to political sophistication are examined. The results indicate that important information receives more weight than unimportant information. In addition, the evidence suggests that political sophisticates are more efficient on-line processors than are less sophisticated individuals. The implications of these results for models of candidate evaluation are discussed. 相似文献

There is increasing evidence that issues influence voter preferences during the nomination campaign (Bartels, 1985; Bartels, 1988); however, only Bartels (1988) and Conover and Feldman (1986, 1989) have examined how partisans forge perceptions of candidates' positions on issues prior to the general election campaign. The goal of this paper, then, is to examine how individuals develop perceptions of candidates' issue positions during the crucial months leading to the nominating conventions. Relying on theories developed in social-psychology, I tested five competing hypotheses known to influence individuals' perceptions of candidates' issue positions. An examination of the findings revealed that there is strong support for one of the hypotheses and modest support for three additional hypotheses. In summary, it appears that voters are quite ingenious in forming impressions of where candidates stand on the issues. They rely on stored information about politics, they actually adjust candidates' true positions to relieve cognitive inconsistencies, they evoke their own issue positions to assume candidates they like agree with them and candidates they dislike disagree with them, and finally they evoke their own issue positions to assume candidates agree with them even when they hold no sentiment toward the candidate. 相似文献

The role of governmental risk aversion in the decision to privatize the production of goods and services has not been examined closely. Using a model of a risk-averse, single-service Niskanen bureaucrat, we determine the conditions under which a bureaucrat will prefer to privatize rather than produce in-house. If the private-sector firm is risk neutral, the result will be a fixed-fee contract with complete insurance. If the private-sector firm is risk averse, the result will be a cost-plus contract with the degree of cost sharing determined by the bureaucrat's share of total risk aversion. In both cases, the bureaucrat's sponsor may affect the likelihood of privatization by manipulating the rewards and penalties imposed on the bureaucrat. 相似文献

The community power debate concluded with each side believing they had won. Political theorists have generalized power, making empirical investigation very difficult; urban scholars have turned their attention to more manageable empirical problems. Rational choice advances the debate, exposing the errors of all sides and facilitating a new approach which transcends structural versus individualist methods. By separating various aspects of power in urban contexts, complementary techniques such as network analysis in a bargaining framework, semi-structured interviewing and the use of text databases permits a comprehensive investigation of agenda-setting and the mobilization of bias. The paper demonstrates the utility of this approach by comparing it to 'regime theory', the latest paradigm of urban research. 相似文献

This article outlines the views of children and parents involved in family law disputes, about the need for and appropriateness of children's participation in decisions regarding residence and contact arrangements. Ninety parents and 47 children (ranging in age from 6 to 18 years) who had been through parental separation, were interviewed. Both parents and children had a range of views about the general appropriateness and fairness of children being involved, but the great majority, particularly of parents, thought that children should have a say in these matters. Core findings of the study include the considerable influence that older children had over the arrangements either in the aftermath of the separation or in making further changes over time, and the higher stated need of children who had experienced violence, abuse, or high levels of conflict to be heard than those in less problematic and noncontested matters. Parents involved in contested proceedings supported the participation of children at a younger age than those who were not. There was a reasonable degree of agreement between parents and children about the need for children to be acknowledged and the value of their views being heard in the decision‐making process. Parents, however, expressed concern about the pressure and manipulation that children can face and exert in this process, whereas children were generally more concerned about the fairness of the outcomes, and maintaining their relationships with their parents and siblings. 相似文献

This article seeks to briefly evaluate the context behind the development of regulations related to chromium pollution control in metal finishing industries. The available evidence suggests the possibility of elevation of the issue to the agenda for agency rule‐making, and subsequent implementation can occur even in the absence of focusing events. Based on historical evidence, this article illustrates that gradual accumulation of knowledge of harmful effects of chromium over the period of decades has been instrumental in the formulation and implementation of standards and guidelines to regulate chromium in the environment under major statutes such as the Clean Air Act, the Clean Water Act, the Safe Drinking Water Act, and so on. The implementation of command and control regulations has resulted in appreciable reduction of chromium released into the environment, thereby minimizing the impact on human health and the environment. However, achieving full compliance from metal finishing industries is still an illusion. There are examples of violations committed by industries. In response to this realization, policy evolution in the chromium pollution control domain has occurred in two directions: (1) gradual replacement of existing standards with more stringent standards and guidelines and (2) emphasis on multimedia, voluntary, and participatory approaches to improve compliance. But the results from the latter are not as dramatic as previously envisioned. Borrowing from the experience of the Common Sense Initiative (CSI), this article argues that consensus‐based, multistakeholder collaboration can be a policy development tool. 相似文献

Penetrating stab wounds of the brain are uncommonly seen in modern times and occur almost exclusively in homicides. We report an unusual death by self-stabbing. A 24-year-old man was found dead at home, the handle of a kitchen knife protruding from his forehead. Data such as the psychiatric history of the victim, the multiplicity and site of wounds, the implement used, the presence of hesitation, and defense wounds were studied to elucidate the manner of death, and the suicidal nature of the event was established after police investigation. Atypical injuries require a careful forensic investigation, and medico-legal aspects of the differentiation between homicide and suicide are discussed in this particular case. A review of the literature revealed few cases of suicidal transcranial stab wounds. 相似文献
