A widely noted and oft-decried characteristic of campaigns in the United States is the tendency of the competing sides to talk past each other—to avoid engaging with one another on the same issues. We bring a massive database on statements by the major-party presidential candidates and other campaign spokespersons in the 1960 through 2000 elections to bear on the question of issue convergence. Far from the exception, a high degree of similarity in the issue emphases of the two sides appears to have been the norm in these campaigns. This result suggests the need to rethink some influential empirical, formal, and normative perspectives on campaigns.  相似文献

Whether competitive bidding or negotiated sale leads to lower borrowing cost for municipal debt issuers has been studied extensively in municipal finance research. There is a potential self-selection bias when estimating the relative cost effectiveness of these two methods of sale. This article argues that sale method can be viewed as a certification mechanism as issuers self-select themselves into either competitive or negotiated groups based on their perception of the underlying degree of information asymmetry. By correcting for this self-selection bias, we find that for issues with no or little information asymmetry, neither sale method has a significant cost advantage over the other.  相似文献

This paper compares the environmental belief systems of elites and publics in Shizuoka Prefecture, Japan, and Spokane County, Washington State. The central question posed is whether the shared forces of postindustrialism generate similar belief structures among elites in nations with quite distinct cultural, political, and historical backgrounds. As a prototypical postindustrial policy area, natural resource/environmental politics is used as the specific issue domain of study. The results emerging from this comparative inquiry reveal substantial differences between the Japanese and American local area elites in the structuring of environmental beliefs, especially in the role of postindustrial orientations. The results also suggest much larger differences in belief system content and structure between elite and general public samples in the Spokane area than in Shizuoka Prefecture.  相似文献

Much of the rational choice literature suggests that constituency considerations will dominate decision-making when constituency concerns are pronounced and the issue is conducive to citizen audit. The 1990 House of Representatives vote on a constitutional amendment banning flag burning provides a good test of this argument. Drawing from a survey of legislators and polling data we argue that even in the face of salient constituency views legislators demonstrated a willingness to vote their policy views and cross their constituents. We explore how concerns about reputation and other considerations contributed to this phenomenon. We also suggest directions for future research.  相似文献

This paper presents time series evidence on the voting behavior of members of the U.S. House of Representatives from 1975 to 1990. The empirical results indicate that voting behavior of individual congressmen is remarkably stable over time. We find no evidence of economically significant last term effects on voting behavior, nor are there important effects of legislative tenure on voting patterns. The most significant deviations in voting behavior occur for congressmen who failed to win their reelection bid, suggesting that sizable deviations from previous policy positions may result in swift retribution by constituents in the district.  相似文献

The relationship between economic hardship and adolescent aggression has been explored from various perspectives. Using survey and observational data on two-parent families in a midwestern rural county, the study identifies four important mechanisms that link economic hardship to the aggressive behavior of adolescents. Economic pressure stemming from low income, financial loss, and unstable work, adversely affects the marital relationship through the negativity of fathers. Negative marital interactions increase irritable parenting, making adolescent aggression more likely.This paper is based on collaborative research involving the Iowa Youth and Families Project at Iowa State University, Ames, and the Social Change Project at University of North Carolina — Chapel Hill. The combined research effort is currently supported by the National Institute of Mental Health (MH43270), the National Institute on Drug Abuse (DA05347), the John D. and Catherine T. MacArthur Foundation Program for Successful Adolescence, the Bureau of Maternal and Child Health (MCJ-109572), and a Research Scientist Award (MH00567).Ph.D. in sociology from University of North Carolina at Chapel Hill.

Federal regulation of child labor (unlike that passed in early nineteenth century England) did not materialize until the New Deal of the 1930s. The present paper examines, using anecdotal and empirical evidence, the motives underlying the passage of depression-based child labor legislation embodied in the Senate vote on the Fair Labor Standards Act (FLSA). Our study, which utilizes both dichotomous and trichotomous probit models of the vote, finds evidence that there were critical and dominantprivate as opposed to public interests behind the restrictions that the FLSA placed on child labor and the exemptions that it established.  相似文献

This study evaluates the effectiveness of state child safety seat laws in the United States. Data for all fifty states for the period 1975 to 1994 are used. Pooled time series analysis is employed to estimate a model of the rate of fatalities suffered by children ages 0–5 years as occupants in automobile crashes. The occupant fatality rate for children 6–11 years of age is used as a comparison group to control for other trends not introduced in the estimated models. The results show that child safety seat policies have significantly reduced fatality rates among children 0–5 years of age. For each additional year of age covered by a state statute, this fatality rate drops 4.8%. A similar reduction in the fatality rate of the older age cohort (6–11 years old) was not observed.  相似文献

One of the tasks of the European project entitled “Collaborative Harmonisation of Methods for Profiling of Amphetamine Type Stimulants” (CHAMP) funded by the sixth framework programme of the European Commission was to develop a harmonised methodology for MDMA profiling and the creation of a common database in a drug intelligence perspective. Part I was dedicated to the analysis of organic impurities formed during synthesis in order to investigate traffic tendencies and highlight potential links between samples, whereas this part focuses on physical characteristics of the MDMA tablets. Diameter, thickness, weight and score were demonstrated to be reliable and relevant features in this drug intelligence perspective. Distributions of samples coming from the same post-tabletting batch (post-TB) and samples coming from different post-TB were very well discriminated by using the squared Euclidean or the Manhattan distance on standardised data. Our findings demonstrated the possibility to discriminate between MDMA samples issued from different post-TB and to find out links between samples coming from a same post-TB. Furthermore, the hypothesis that most of the MDMA samples found on the international market come from the same countries was supported.  相似文献
