The link between resource deprivation and urban violence has long been explored in criminological research. Studies, however, have largely ignored the potential for resource deprivation in particular communities to affect rates of violence in others. The relative inattention is notable because of the strong theoretical grounds to anticipate influences that extend both to geographically contiguous areas and to those that, though not contiguous, share similar social characteristics. We argue that such influences—what we term spatial and social proximity effects, respectively—constitute a central feature of community dynamics. To support this argument, we develop and test theoretically derived hypotheses about spatial and social proximity effects of resource deprivation on aggregated and disaggregated homicide counts. Our analyses indicate that local area resource deprivation contributes to violence in socially proximate communities, an effect that, in the case of instrumental homicides, is stronger when such communities are spatially proximate. We conclude by discussing the implications of our findings for theories focused on community‐level social processes and violence, and for policies aimed at reducing crime in disadvantaged areas. 相似文献

More than a decade after NAFTA (North American Free Trade Agreement) entered into force, the environmental effects of agricultural
trade liberalization in Mexico are still controversial, emerging, and not fully understood. This paper contributes to the
literature that aims to explore trends in input use in the agricultural sector in Mexico during the post-NAFTA period among
both commercial/industrial and traditional/rainfed farmers, and examines the influence of the national and multilateral institutional
framework on these outcomes. We decompose the post-NAFTA agricultural production data into scale, technique and composition
effects to estimate the impact that trade liberalization has had on the use of fertilizer and land use, two key agricultural
inputs for which reliable aggregate data is available. We conclude that among commercial farmers patterns of crop type specialization
and significant technological improvements have led to some declines in fertilizer use but they have been offset by growth
in fertilizer use associated with growing agricultural output. Among traditional farmers increased output and specialization
in land-intensive grain crops are contributing to an increase in land under cultivation and technological improvements show
the potential, but not yet not the strength, to counteract these effects. We analyse the environmental institutional framework
and rural development plans, observing that institutional weaknesses have, in several instances, reduced the environmental
benefit of technique and composition effects. We conclude with recommendations about how the Mexican agricultural sector might
reap the environmental benefits of international agricultural trade. 相似文献

Despite the recent increase in public and professional interest in the problem of wife beating in Arab society, in Israel, and in the rest of the Arab world, there is a serious lack of empirical research on different dimensions of the problem in those societies. This paper presents the results of a survey conducted among a systematic random sample of 362 Arab husbands from Israel, in an attempt to examine the contribution of patriarchal ideology toward explaining their beliefs about wife beating. Although about 58% of the participants indicated that there is no excuse for a man to beat his wife, 15–62% still justified wife beating on certain occasions (e.g., adultery, failure to obey husbands, disrespect for parents and relatives). In addition, although the participants tended to perceive abusive and violent husbands as responsible for their behavior, 52% still expressed understanding of that behavior and, on some occasions, 23–43% even blamed the wife for violence against her. Regression and multiple regression analyses revealed that over and above the participants' age and level of education, their masculine sex-role stereotypes, negative and traditional attitudes toward women, nonegalitarian marital role expectations, and familial patriarchal beliefs were the most significant predictors of beliefs about wife beating. Implications of the results and limitations of the study are also discussed. 相似文献

How partner violence is transferred across generations is relatively unexplored. This paper proposes that anger expression style (constructive, destructive direct, destructive indirect) mediates the relationship between exposure to family violence and dating violence perpetration by adolescents. Data are from 1,965 completed self-administered questionnaires given to eighth- and ninth-grade students in a primarily rural county in North Carolina in 1994. Results varied by gender and type of exposure to family violence. For females, destructive direct and destructive indirect anger expression styles mediated the relationship between experiencing family violence and dating violence perpetration. For males, this relationship was mediated primarily by destructive direct anger expression style. The association between witnessing family violence and dating violence perpetration for females was mediated by destructive direct anger expression style only. Witnessing family violence was not associated with dating violence perpetration for males, and therefore could not be mediated. This study suggests that adolescents exposed to family violence learn anger expression styles that put them at risk of being perpetrators of dating violence. Further research is needed to identify other mediators that explain how partner violence is transferred across generations. 相似文献

随着互联网和人工智能的快速发展,恐怖主义活动方式变得更为隐秘。网络恐怖主义活动空间从表网的在线社区与视频分享平台转向暗网黑市交易和暗网论坛。针对暗网节点通信和交易信息高度匿名等特点,相应的反恐工作需要采取新的技术手段,以深度切入恐怖分子用于扩大影响的暗网空间。为此,可以设计和优化专门适用于暗网的聚焦爬虫工具,挖掘恐怖主义活动信息;可以搭建涉恐事件数据模型,分析恐怖组织可能的线下攻击手段;可以利用社会网络分析和超链接分析方法,定位暗网内恐怖主义隐蔽社区和危险用户集群。通过准确把握暗网中的匿名恐怖主义活动规律,抓住安全监控与防范的重点、难点,综合施策,以及适时制定和精准实施反恐网络安全策略,能够最大限度遏制暗网恐怖主义的危害,保护国家安全和人民利益。 相似文献

ABSTRACT Intimate partner violence (IPV) continues to be an urgent social problem, despite decades of intervention and prevention efforts. Restorative justice programs (e.g., victim impact panels) may be a useful addition to intimate partner violence (IPV) intervention, but it is unclear how these panels operate and to what extent they are consistent with restorative justice models. This naturalistic study of IPV surrogate impact panels used ethnographic observation of panels (n = 18), archival analysis of audience responses to the panel (N = 287), and focus groups and interviews (k = 4) with IPV survivors, an audience member, and batterer intervention providers to investigate these gaps. Findings suggest the panels manifest interactional processes consistent with restorative justice principles. Implications, limitations, and future aims of research on these panels are discussed. 相似文献

Husbands' and wives' reports (n=97 couples) of engaging in or experiencing marital aggression were compared to determine congruence. Congruence was defined as spousal agreement on whether either spouse had been nonviolent, mildly violent, or severely maritally violent within the past year. Whereas approximately equal numbers of clinic couples were incongruent for husband and for wife violence (32% vs. 31%), only incongruence for husband violence (H W) was found to correlate with reports of affective and relationship functioning. Incongruent H W wives were more likely to be depressed and angry. H W incongruent wives were also more negative about the inter-spousal communication and rated the relationship as more unsatisfactory for them than did congruent wives. Incongruent H W husbands also perceived the relationship more negatively, but their levels of depression and anger did not differ from congruent H W husbands. These findings were not replicated for spouses who were incongruent for wife violence. Our results support the conclusion that spousal disagreement about H W violence has a more negative impact than does disagreement about wives' level of aggression. 相似文献
