The often changing range of terrorism journals selected for indexing in various databases adds to the elasticity of this field's definition. The electronic databases as well as websites change their format and content quite often and this instability hampers the formation of a clear delineation of the disciplinary boundaries of terrorism. Nevertheless, the integration of electronic databases into terrorism research has exposed researchers to a large number of journals that deal with various aspects of terrorism, and the boundaries of this subject are continually expanding to encompass new sub-areas. In addition to the known core journals covering terrorism, many peripheral journals are emerging that are concerned with the dynamics of this field. The exposure of researchers to such a massive amount of information, print and electronic, demonstrates a marked knowledge growth in this area of study. However, the field could become so broad, even before reaching disciplinary maturation, that it could defy any attempt at delineation.‐  相似文献

For a long time, criminologists have contended that neighborhoods are important determinants of how individuals perceive their risk of criminal victimization. Yet, despite the theoretical importance and policy relevance of these claims, the empirical evidence base is surprisingly thin and inconsistent. Drawing on data from a national probability sample of individuals, linked to independent measures of neighborhood demographic characteristics, visual signs of physical disorder, and reported crime, we test four hypotheses about the mechanisms through which neighborhoods influence fear of crime. Our large sample size, analytical approach, and the independence of our empirical measures enable us to overcome some of the limitations that have hampered much previous research into this question. We find that neighborhood structural characteristics, visual signs of disorder, and recorded crime all have direct and independent effects on individual‐level fear of crime. Additionally, we demonstrate that individual differences in fear of crime are strongly moderated by neighborhood socioeconomic characteristics; between‐group differences in expressed fear of crime are both exacerbated and ameliorated by the characteristics of the areas in which people live.  相似文献

Several studies with older children have reported a positive relationship between parental use of corporal punishment and child conduct problems. This has lead some social scientists to conclude that physical discipline fosters antisocial behavior. In an attempt to avoid the methodological difficulties that have plagued past research on this issue, the present study used a proportional measure of corporal punishment, controlled for earlier behavior problems and other dimensions of parenting, and tested for interaction and curvilinear effects. The analyses were performed using a sample of Iowa families that displayed moderate use of corporal punishment and a Taiwanese sample that demonstrated more frequent and severe use of physical discipline, especially by fathers. For both samples, level of parental warmth/control (i.e., support, monitoring, and inductive reasoning) was the strongest predictor of adolescent conduct problems. There was little evidence of a relationship between corporal punishment and conduct problems for the Iowa sample. For the Taiwanese families, corporal punishment was unrelated to conduct problems when mothers were high on warmth/control, but positively associated with conduct problems when they were low on warmtwcontrol, An interaction between corporal punishment and warmth/Wcontro1 was found for Taiwanese fathers as well. For these fathers, there was also evidence of a curvilinear relationship, with the association between corporal punishment and conduct problems becoming much stronger at extreme levels of corporal punishment. Overall, the results are consistent with the hypothesis that it is when parents engage in severe forms of corporal punishment, or administer physical discipline in the absence of parental warmth and involvement, that children feel angry and unjustly treated, defy parental authority, and engage in antisocial behavior.  相似文献

We examine whether gang membership is associated with higher levels of delinquency because boys predisposed to delinquent activity are more likely than others to join. We use 10 years of longitudinal data from 858 participants of the Pittsburgh Youth Study to identify periods before, during and after gang membership. We build on prior research by controlling for ages and calendar time, by better accounting for gang memberships that occurred before the study began, and by using fixed effects statistical models. We find more evidence than has been found in prior studies that boys who join gangs are more delinquent before entering the gang than those who do not join. Even with such selective differences, however, we replicate research showing that drug selling, drug use, violent behaviors and vandalism of property increase significantly when a youth joins a gang. The delinquency of peers appears to be one mechanism of socialization. These findings are clearest in youth self-reports, but are also evident in reports from parents and teachers on boys' behavior and delinquency. Once we adjust for time trends, we find that the increase in delinquency is temporary, that delinquency falls to pre-gang levels when boys leave gangs.  相似文献
