This article draws on a new dataset of House primary‐ and general‐election outcomes (1956–98) to examine the relationship between primary elections and candidate ideology. We show that, like presidential candidates, congressional candidates face a strategic‐positioning dilemma: should they align themselves with their general‐ or primary‐election constituencies? Relative to general‐election voters, primary voters favor more ideologically extreme candidates. We show that congressional candidates handle the dilemma by positioning themselves closer to the primary electorate. This article thus supports the idea that primaries pull candidates away from median district preferences. 相似文献

Research on offense specialization has concluded that there is a great deal of versatility in offending. Although the preponderance of evidence supports versatility, some research points to a small but significant tendency to specialize. Beyond this observation there is little consensus over the degree of offense specialization, the similarities and differences between people who commit violent acts and those who engage in other criminal behavior, or the extent to which general causal processes are sufficient to explain variation in diverse forms of crime and delinquency. At the heart of the confusion is the fact that criminal behaviors across a wide spectrum are positively correlated with one another. In our opinion, the conclusion that general offending trumps offense specialization is the result of research designs that predetermined such a conclusion. We propose an alternative method, marginal logit modeling, that supports many desirable features suited to the investigation of offense specialization. We analyze nine self‐reported delinquent behaviors (with a tenth category representing “No Offense”) from the Add Health study. We show that violent offenders are more likely to engage in additional violent offenses, nonviolent offenders are more likely to engage in additional nonviolent offenses. For some offense types, we find no evidence of a tendency to commit both violent and nonviolent offending. For others, the offense generalization effect is weak compared to the offense specialization effect. 相似文献

This research reassesses the role of policing and drugs in the sharp homicide decline in New York City in the 1990s. Drawing on theoretical arguments about “broken windows” policing and lethal violence associated with the diffusion of crack cocaine, we estimate the effects of measures of misdemeanor arrests and cocaine prevalence on homicide rates with pooled, cross‐sectional time‐series data for 74 New York City precincts over the 1990–1999 period. The results of mixed regression models reveal a significant negative effect of changes in misdemeanor arrests and a significant positive effect of changes in cocaine prevalence on changes in total homicide rates. Additional analyses of homicide disaggregated by weapon indicate that the effects of misdemeanor arrests and cocaine prevalence emerge for gun‐related but not for non‐gun‐related homicides. Overall, the research generally supports influential interpretations of the homicide decline in New York City but also raises questions about underlying mechanisms that warrant more inquiry in future research. 相似文献

In this paper, we extend recent work exploring the prevalence of outlying committees in American state legislatures. Using an expanded sample of 45 states and measures of legislator preferences generated by a single, federated group, we find that most legislative committees are representative of the parent chambers from which their members are selected. Furthermore, we test multivariate models designed to account for theoretically relevant patterns in variations in outlier percentages among control and noncontrol committees. The fact that our models are such poor predictors of nonrepresentative committees speaks to the idiosyncratic nature of the relatively small percentage of outlying committees in the states. This conclusion, in turn, provides further support for the proposition that representative committees are simply rational. 相似文献

A year after the United States Supreme Court decided Crawford v. Washington, 541 U.S. 36 (2004), the maelstrom that many legal scholars anticipated has failed to materialize. Crawford's abrogation of Ohio v. Roberts, 448 U.S. 56 (1980), and its articulation of the new standard for determining when the Sixth Amendment's Confrontation Clause applies to out‐of‐court statements, has had less effect than some predicted, regarding which statements are admissible and which are excluded. This article explores Crawford's practical effect as courts around the country have applied it, particularly in the context of child abuse and domestic violence cases. 相似文献

The federal unified budget reports social security program results on a cash flow basis. Policy is established through projections of cash flows for 75 years into the future. This paper discusses how reliance on cash flow accounting and projections disguises an inherent upside cash flow bias that makes the program's finances appear better than they actually are and, when combined with the long‐standing pay‐as‐you‐go funding policy, leads to periodic solvency crises. The paper does not propose changing the budgetary accounting basis from cash to accrual but does explore the possible application of accrual accounting to the social security program for reporting purposes. 相似文献

This article reports a study concerning perceptions of benefit fraud staff and of management concerning their own interviewing techniques and standards, and their views pertaining to a preferred model of interviewing. Interviewing fraud suspects forms an important task performed by Fraud Investigators (FIs) within the Department of Work and Pensions (DWP) in the UK. Given this significance, it is surprising that there has been little analysis of the skills used to do this task. Current training consists of a course centred on an interviewing framework called the PEACE model, which was originally developed for police use. The research outlined in this paper examined both FIs and their managers’ perceptions and attitudes of the model and of their own practices. It was found that, while there was general support for the model, reservations were voiced over how effective PEACE may actually be in practice. These reservations centred on insufficient time to prepare for investigations along with a perceived inflexibility over the model’s framework. In, addition, it was highlighted that the absence of any national supervisory framework for investigative interviews should give the organization cause for concern in ensuring standards. 相似文献
