This paper explores the organizational strategies used to represent information about political actors in memory, and it illustrates the usefulness of a specific measure, the adjusted ratio of clustering score (ARC), for inferring memory structure. Assuming the operation of an associative network model, we argue that information about a political actor can be organized along three distinct dimensions: attribute type (differentiating between issue positions and personal attributes), partisanship (differentiating between characteristics typical of Republicans and Democrats), and evaluative type (differentiating between positively and negatively evaluated attributes). The results of a laboratory study indicate that organization along the attribute type dimension was most common, with some evidence of partisan organization. There was no evidence of organization along the evaluative dimension. The implications of the study for understanding individual differences in political reasoning, and the consequences of memory organization strategies, are discussed. 相似文献

In this paper we develop an econometric model to test whether alienation and/or mobilized voting explain urban-rural turnout in Korea. We find that a person's decision to vote is influenced by the act of mobilization and that it affects rural residents more strongly. But we do not find that the feeling of alienation affects a person's decision to vote. Thus, we find support for the mobilized voting hypothesis, but not for the alienation nonvoting hypothesis. 相似文献

This paper investigates the effectiveness of New Jersey's mandatory belt use law (MUL) by testing specifically for: (1) a safety effect, and (2) a risk-compensation effect that could offset (in part) any safety impact. The main findings are that injury severity declined significantly in the 22 months following implementation of the MUL; but that accident frequency increased significantly. The increase in accidents may be explained only partially by increased driving mileage. These findings suggest that the real safety effect of the law may have been diluted by risk-compensating behavior.This paper is based on a study conducted for the New Jersey Office of Highway Traffic Safety by the Rutgers University Bureau of Economic Research. We are grateful to William Ascher and two referees for useful comments. 相似文献

This article analyzes the impact of the Gramm-Rudman-Hollings (GRH) Act on federal budgetary and fiscal outcomes. Rather than portraying it as a two-on federal budgetary and fiscal outcomes. Rather than portraying it as a two-party game between Congress and the president, each with monolithic policy preferences, we view GRH as a multiparty negotiation game among advocates of different programs and agencies. In this game, agencies subject to sequestration and their congressional advocates have an incentive to reach a budget accord, while those exempt from sequestration do not. Consistent with this argument, we find that GRH has restrained outlays for nonexempt programs and that exempt programs have, if anything, experienced more rapid growth. Overall, GRH is estimated to have restrained outlays by $59 billion by fiscal 1989, and to have restrained outlays more effectively after the 1987 modifications in the Act. The Gramm-Rudman-Hollings Act signals another phase in the decade-long struggle between the White House and Congress over public spending priorities. Our final counterfactual analysis suggests that GRH partially returned federal fiscal and budgetary relationships and priorities to those that prevailed before Reagan. 相似文献

The assumption that candidates make a difference to electoral outcomes in British general elections is tested through a comparison of the 1983 and 1987 general elections. Incumbent's Constituency-specific Vote Change (ICVC) between the June 1983 and June 1987 British general elections is measured by subtracting the average regional vote change for the incumbent's party from the constituency vote change registered by the incumbent. Regression analysis finds ICVC to be most significantly influenced in both the Labour and Conservative parties by the incumbent's length of tenure, displayed especially in the higher ICVC registered by first-term incumbents than by more senior incumbents. Variables indicating the security or insecurity of the seat in electoral terms are significantly related to ICVC in the Conservative but not in the Labour case. The findings for Labour indicate ICVC to be greater where electoral security is greater. This finding might be explained by successful Conservative party concentration on constituencies in which Labour incumbents appear to be vulnerable. 相似文献
