Aim was to investigate a range of potentially modifiable risk factors for boys in late childhood for later violence and homicide convictions. Boys from the Pittsburgh Youth Study (N = 1,517) were measured through self-reports and official records in late childhood (ages 11–13) on a large number of potentially modifiable risk factors, and were followed up in juvenile and adult criminal records in terms of violence and homicide. Predictors of conviction for homicide largely overlapped with predictors of conviction for violence. Twenty three out of 28 possible risk factors significantly predicted later violence convictions. Regression analysis identified four significant modifiable risk factors in late childhood for any violent offenders: physical abuse, parental stress, bad friends and low school motivation. The higher the number of early risk factors, the higher the probability of later conviction for violent offenses including homicide. The discussion focus on single-, and multi-modal interventions in late childhood to reduce later violence and possibly homicide. 相似文献

Mates appear to assort on political attitudes more than any other social, behavioral, or physical trait, besides religion. Yet the process by which ideologically similar mates end up together remains ambiguous. Mates do not appear to consciously select one another based on ideology, nor does similarity result from convergence. Recently, several lines of inquiry have converged on the finding that olfactory processes have an important role in both political ideology and mate selection. Here we integrate extant studies of attraction, ideology, and olfaction and explore the possibility that assortation on political attitudes may result, in part, from greater attraction to the scent of those with shared ideology. We conduct a study in which individuals evaluated the body odor of unknown others, observing that individuals are more attracted to their ideological concomitants. 相似文献

Why do governments choose multilateralism? We examine a principal-agent model in which states trade some control over the policy for greater burden sharing. The theory generates observable hypotheses regarding the reasons for and the patterns of support and opposition to multilateralism. To focus our study, we analyze support for bilateral and multilateral foreign aid giving in the US. Using new survey data, we provide evidence about the correlates of public and elite support for multilateral engagement. We find weak support for multilateralism and deep partisan divisions. Reflecting elite discourse, public opinion divides over two competing rationales—burden sharing and control—when faced with the choice between multilateral and bilateral aid channels. As domestic groups’ preferences over aid policy diverge from those of the multilateral institution, maintaining control over aid policy becomes more salient and support for multilateralism falls. 相似文献

The Problem of Political Science: Political Relevance and Scientific Rigor in Aristotle's “Philosophy of Human Affairs” 下载免费PDF全文
Dustin Sebell 《American journal of political science》2016,60(1):85-96
Treatments of Aristotle's moral‐political science have largely disregarded the methodological statements that he delivers as he embarks on his “philosophy of human affairs” in book I of the Nicomachean Ethics. A consideration of these statements, however, lends critical support to the view that Aristotle sought to give the sharpest possible expression to ordinary moral‐political opinion. Moreover, apart from revealing the by‐no‐means ordinary reasons that induced Aristotle to do so (and to do so in contrast to Plato), such a consideration sheds light on the source of the vagueness or ambiguity that defines moral‐political opinion as such. Indeed, the methodological statements are perhaps the first entries in the old quarrel of “relevance versus rigor.” And, through them, Aristotle suggests how political scientists today might walk a fine line between “politics,” on one hand, and “science,” on the other, without losing sight of the ultimate tension between them. 相似文献

Preferential Trade Agreements (PTAs) have become the most prevalent form of international trade liberalization in recent decades, even though it remains far from clear what their effects on economies and their key units, firms, are. This paper evaluates the distributional consequences of trade liberalization within industries differentiating two distinct aspects in which trade liberalization could result in higher trade flows: the intensive vs. the extensive margin of trade. In particular, we analyze whether trade liberalization leads to increased trade flows because either firms trade more volume in products they have already traded before (intensive margin) or because they start to trade products they have not traded previously (extensive margin), or both. We test these arguments for the Dominican Republic–Central America–United States Free Trade Agreement (CAFTA-DR) and exporting firms based in Costa Rica for the time-period 2008–2014. The results of our study suggest that the effects of CAFTA-DR depend not only on whether we analyze the extensive versus the intensive margin of trade but also whether the product in question is homogenous or differentiated and whether the exporting firm under analysis is small or large. In particular, we find support for the theoretical expectation that firms exporting heterogeneous products, such as textiles, gain from trade agreements, such as CAFTA-DR, in that they can export more varieties of their products. Yet at the same time, they tend to lose at the intensive margin by a reduction in their trade volume while the opposite pattern occurs for firms exporting homogenous products. 相似文献

From January 1979 to December 2009, the Maoist insurgent Shining Path committed a total of 9,034 violent acts in a concerted attempt to topple the Peruvian government. These acts of violence included bombings, armed assaults, and assassinations. The Shining Path's leader Abimael Guzmán was captured by the Peruvian government on 12 September 1992. Using quarterly data and an interrupted times-series AutoRegressive Integrative Moving Average (ARIMA) study design, we investigated the effect of Abimael Guzmán's capture on the ability of the Shining Path to wage its war against the Peruvian government. Maximum-likelihood results revealed that the frequency of terrorist acts committed by the Shining Path dropped by 143 incidents per quarter a short time after Guzmán was captured. The analysis also evinced a positive relationship between the lethality of attacks and the frequency of the Shining Path's terrorist activity. We conclude that targeted capture shows some promise as an effective counterterrorism strategy, at least for terrorist groups such as the Shining Path that have a top-down type of organizational structure. 相似文献
