Research on the temporal distribution of criminal behavior has highlighted two distinct mechanisms—population heterogeneity and state dependence. Most of this work indicates that long-term patterns of criminal offending reflect a mixture of stable individual differences and the causal effect of life events and experiences. Yet several ambiguities remain. Among the most important of these problems is whether both population heterogeneity and state dependence processes operate for different types of offending. We use longitudinal official record and self-report data for violent and non-violent offending activity from the Rochester Youth Development Study to address these ambiguities. 相似文献

Registrants,Voters, and Turnout Variability Across Neighborhoods 总被引:1,自引:0,他引:1
Although political participation has received wide-ranging scholarly attention, little is known for certain about the effects of social and political context on turnout. A scattered set of analyses—well-known by both political scientists and campaign consultants—suggests that ones neighborhood has a relatively minor impact on the decision to vote. These analyses, however, typically rely upon data from a single location. Drawing on official lists of registered voters from sixteen major counties across seven states (including Florida) from the 2000 presidential election, we use geographic/mapping information and hierarchical models to obtain a more accurate picture of how neighborhood characteristics affect participation, especially among partisans. Our research shows that neighborhoods influence voting by interacting with partisan affiliation to dampen turnout among voters we might otherwise expect to participate. Most notably, we find Republican partisans in enemy territory tend to vote less than expected, even after accounting for socioeconomic status. Our findings have implications for campaign strategy, and lead us to suggest that campaign targeting efforts could be improved by an integration of aggregate- and individual-level information about voters. 相似文献

Over the last decade, Switzerland has been characterized by both a radicalization of its political system and the relative success of the SP and SVP parties, which tend to adopt a strategy of permanent campaigning. Because of this, it is often argued that politicians are held accountable for their behaviour and that their electoral successes depend on their voting behaviour in parliament. We thus explore whether the voting behaviour of representatives, or citizens' evaluations of parties' ideological positions had an impact on their electoral success in the 1995, 1999, and 2003 national elections. More precisely, we assess how far the proximity and directional models explain the electoral success of incumbents and parties using roll call data for the National Council as well as the Selects surveys at the individual level. The results at both levels suggest that voters' choice is largely consistent with what is predicted by the spatial models of electoral behaviour. Swiss voters form their party preference on both proximity and direction, which supports a mixed model of electoral behaviour. 相似文献

This study investigated the intergroup perceptions of 2 social groups. English adolescents aged 14–15 years were asked to make causal attributions for various positive and negative behaviors performed by members of an in-group and an out-group. In the first condition (n = 45), participants rated members of their own peer group and members of a peer group to which they did not belong. Participants in the second condition (n = 45) rated English adolescents and members of a national out-group (either France or Germany). Results showed that participants in both conditions reported perceptions that were biased towards the formation of a favorable in-group evaluation. However, the relationship between intergroup discrimination and identification with the in-group was in the expected direction for participants in the peer group condition only. This observation is explained in terms of the potential level of identity threat posed by the prevalent intergroup context. 相似文献

Understanding preferences over government spending is important for understanding electoral behavior and many other aspects of the political world. Using data on relative preferences for more or less spending across different issue areas, we estimate the general spending preferences of individuals and congressional candidates along a left-right spending dimension. Our modeling approach also allows us to estimate the location of policies on this same dimension, permitting direct comparison of people's spending preferences with where they perceive policy to be. We find that public shows very low levels of polarization on spending preferences, even across characteristics like partisanship, ideology, or income level. The distribution of candidates' spending preferences shows much more sorting by party, but candidates are significantly less polarized than is contemporary voting in Congress. 相似文献

The purpose of this review paper is to highlight various geomatic techniques that crime scene reconstructionists or forensic practitioners can use to document different kinds of scenes, highlighting the advantages, disadvantages, and when best to use each technology. This paper explores geomatic techniques such as a total station, photogrammetry, laser scanners and structured light scanners and how they can be used to reconstruct crime scenes. The goal of this paper is not to discredit manual methods, as they are long standing and reliable, but instead to shed light on alternative methods that may produce equally or more accurate results with a more visually appealing final product. It is important for law enforcement and forensic professionals to understand the advantages and disadvantages of each technique, knowing when certain techniques should be used (and when they should not), and being able to revert to traditional methods if required. 相似文献

Welfare is the largest expenditure category in all advanced democracies. Consequently, much literature has studied partisan effects on total and policy-specific welfare expenditure. Yet, these results cannot be trusted: the methodological standard is to apply time-series cross-section regressions to annual observation data. But governments hardly change annually. Thus, the number of observations is artificially inflated, leading to incorrect estimates. While this problem has recently been acknowledged, it has not been convincingly resolved. This article proposes mixed-effects models (also known as ‘multilevel models’ or ‘hierarchical models’) as a solution, which allows decomposing variance into different levels and permits complex cross-classification data structures. It is argued that mixed-effects models combine the strengths of existing methodological approaches while alleviating their weaknesses. Empirically, partisan effects on total and on disaggregated expenditure in 23 OECD countries in the period 1960–2012 are studied using several measures of party preferences and revealing several substantially relevant findings. 相似文献
