A good deal of research in recent years has revisited the relationship between immigration and violent crime. Various scholars have suggested that, contrary to the claims of the classic Chicago School, large immigrant populations might be associated with lower rather than higher rates of criminal violence. A limitation of the research in this area is that it has been based largely on cross‐sectional analyses for a restricted range of geographic areas. Using time‐series techniques and annual data for metropolitan areas over the 1994–2004 period, we assess the impact of changes in immigration on changes in violent crime rates. The findings of multivariate analyses indicate that violent crime rates tended to decrease as metropolitan areas experienced gains in their concentration of immigrants. This inverse relationship is especially robust for the offense of robbery. Overall, our results support the hypothesis that the broad reductions in violent crime during recent years are partially attributable to increases in immigration. 相似文献

In a typical year, the United States Employment Service places over 4 million persons from among 16 million applicants. This investigation of which applicants are most likely to be placed shows that placement occurs in two labor market segments, corresponding roughly to the primary and secondary labor markets described in the economic literature. The equity and efficiency implications o f devoting a substantial percentage o f Employment Service resources t o secondary labor market placements are considered. Several states currently use Employment Service data as a source of local labor market information. An argument is made that these states are misusing this data and suggestions for improvements are offered. 相似文献

Research Summary: This evaluation of a directed police patrol project utilizes a pre-post quasi-experimental design with a non-equivalent control group as well as an interrupted time series analysis. The results suggest that directed patrol had an impact on firearms crime in one of the target areas but not the other. Policy Implications: The results suggest that a specific deterrence strategy whereby the police utilize directed patrol to focus on suspicious activities and locations reduced violent gun crime. In contrast, a general deterrence strategy focused on maximizing vehicle stops did not have an apparent effect. 相似文献

Although evidence of the strong correlation between deviant behavior and exposure to deviant peers is overwhelming, researchers have yet to investigate whether a nonlinear functional form better captures this relationship than does a linear form. Researchers also have yet to examine the extent to which peer effects vary as a function of the neighborhood context. To address these issues, we use data from the Project on Human Development in Chicago Neighborhoods (PHDCN) to examine 1) the functional form of the relationship between peer violence exposure and self‐reported violent crime and 2) the extent to which the effect of exposure to violent peers on violence is ecologically structured. Estimates from logistic hierarchical models indicate that the effect of peer violence exposure on violent crime decreases at higher values of peer violence, as reflected in a nonlinear relationship (expressed in terms of log‐odds). Furthermore, exposure to violent peers increases along with neighborhood disadvantage, and the effect of peer violence exposure on violent crime is attenuated as neighborhood disadvantage increases, which is reflected in a cross‐level peer violence/disadvantage interaction. 相似文献

Surveys of citizen satisfaction with local public services have become widespread, with the results increasingly used to reorganize services, to allocate budgets, and to hold managers accountable. But evidence from a split‐ballot experiment that we conducted suggests that the order of questions in a citizen survey has important effects on reported satisfaction with specific public services as well as overall citizen satisfaction. Moreover, the correlations of specific service ratings with overall satisfaction, and thus the identification of key drivers of overall satisfaction, also turn out to be highly sensitive to question order. These findings are in line with research on priming and question order effects in the survey methodology literature, but these effects have not been carefully examined before in the context of citizen surveys and public administration research. Policy and management implications of these finding are discussed. 相似文献

In recent years, criminologists, as well as journalists, have devoted considerable attention to the potential deterrent effect of what is sometimes referred to as “proactive” policing. This policing style entails the vigorous enforcement of laws against relatively minor offenses to prevent more serious crime. The current study examines the effect of proactive policing on robbery rates for a sample of large U.S. cities using an innovative measure developed by Sampson and Cohen (1988). We replicate their cross-sectional analyses using data from 2000 to 2003, which is a period that proactive policing is likely to have become more common than that of the original study—the early 1980s. We also extend their analyses by estimating a more comprehensive regression model that incorporates additional theoretically relevant predictors. Finally, we advance previous research in this area by using panel data, The cross-sectional analyses replicate prior findings of a negative relationship between proactive policing and robbery rates. In addition, our dynamic models suggest that proactive policing is endogenous to changes in robbery rates. When this feedback between robbery and proactive policing is eliminated, we find more evidence to support our finding that proactive policing reduces robbery rates. 相似文献

This article assesses the extent to which the infant mortality rate might be treated as a “proxy” for poverty in research on cross-national variation in homicide rates. We have assembled a pooled, cross-sectional time-series data set for 16 advanced nations from the 1993–2000 period that includes standard measures of infant mortality and homicide and contains information on the following commonly used “income-based” poverty measures: a measure intended to reflect “absolute” deprivation and a measure intended to reflect “relative” deprivation. With these data, we assess the criterion validity of the infant mortality rate with reference to the two income-based poverty measures. Also, we estimate the effects of the various indicators of disadvantage on homicide rates in regression models, thereby assessing construct validity. The results reveal that the infant mortality rate is correlated more strongly with “relative poverty” than with “absolute poverty,” although much unexplained variance remains. In the regression models shown here, the measure of infant mortality and the relative poverty measure yield significant positive effects on homicide rates, whereas the absolute poverty measure does not exhibit any significant effects. The results of our analyses suggest that it would be premature to dismiss relative deprivation in cross-national research on homicide, and that disadvantage is conceptualized and measured best as a multidimensional construct. 相似文献

While all industrialized countries have enacted financial reforms over the past decade, Japan's Ministry of Finance (MoF) officials have crafted a distinctive approach to reform. They have managed to pursue their own agenda while at the same time responding to international market pressures and domestic political demands. This article examines Japan's "financial system reform," the process by which the MoF has recast the regulatory barriers between different types of financial institutions, such as banks and securities houses. Financial system reform represents an extreme case of a common Japanese policy pattern—the bureaucratic-led bargain—in which Japan's bureaucrats, rather than its politicians, organize the bargains that eventually emerge as policy. Two ministry policy councils deliberated for seven years before the Diet passed comprehensive reform legislation in 1992, and the ministry continues to redefine the reform at the stage of implementation today. While MoF officials have been forced to make concessions to industry groups and to adjust to unforeseen developments along the way, they have maintained overall control of the reform process. In fact, this article suggests that they have been remarkably successful in promoting their own peculiar interpretation of the public interest and in preserving and, in some cases, enhancing their own power. 相似文献

Conventional wisdom holds that terrorism has a wide-ranging impact on a polity. At the same time, a complementary, yet less extensive body of research discusses the impact of terrorism on the crux of representative democracy, namely its citizens. In contribution to that literature, and to further explore how external shocks affect public opinions, we propose a two-dimensional analytical framework to examine the effects of the November 2015 terrorist events in Paris and Saint Denis. Drawing from extant scholarship, we argue that we can expect both in-group solidarity and out-group hostility to increase in direct response to these events. This study relies on a regression discontinuity design to analyse a representative survey (DREES) that was in the field at the time of the events. Findings are two-fold. First, and perhaps surprisingly, we find no conclusive evidence of increasing out-group hostilities as a direct consequence of the terrorist events. Second, we find a definite strengthening of in-group solidarity indicators following the events. This not only confirms that citizens adjust their opinions in response to environmental stimuli, but also highlights the democratic resilience of citizens, particularly when faced with a collective threat. Altogether, these findings add to our understanding of why and how individual behaviour changes in light of exogenous shocks. 相似文献
