Youth living in impoverished urban neighborhoods are at risk for becoming hopeless about their future and engaging in violent
behaviors. The current study seeks to examine the longitudinal relationship between social connections, hopelessness trajectories,
and subsequent violent behavior across adolescence. Our sample included 723 (49% female) African American youth living in
impoverished urban neighborhoods who participated in the Mobile Youth Survey from 1998 through 2006. Using general growth
mixture modeling, we found two hopelessness trajectory classes for both boys and girls during middle adolescence: a consistently
low hopelessness class and an increasingly hopeless class with quadratic change. In all classes, youth who reported stronger early adolescent connections to their mothers were less
hopeless at age 13. The probability of later adolescent violence with a weapon was higher for boys and was associated with
the increasingly hopeless class for both boys and girls. Implications for new avenues of research and design of hope-based prevention interventions will
be discussed. 相似文献

中国与拉美社会保障比较:传统文化与制度安排——提高覆盖率的角度 总被引:3,自引:1,他引:2
欧洲、拉丁美洲和中国的文化与社会保障改革取向存在差异性.与西欧相比,拉美和中国之间的相似性更多一些,例如低收入的经济背景、积累性质的融资模式、个人账户的引入等,其改革效果也存在一些相似性.例如覆盖面狭小等.中国和拉美社保覆盖面狭小的原因在于传统文化存在较大差异性,即拉美缺乏储蓄文化,其社保改革之后"对等原则"的引入并没有为提高覆盖率和遵缴率作出很大贡献,但对中国住房公积金制度进行分析和对比之后发现,在浓厚的储蓄文化背景之下,中国社保覆盖率狭小的原因正是由于缺乏"对等原则"因素所致.不同文化背景下,社保制度中"对等原则"效果截然相反.鉴于此,本文认为,如果将目前统账结合制度改造为大账户制或名义账户制,将个人和单位缴费完全划入个人账户,覆盖率和遵缴率就会像住房公积金那样立即提高,实现应保尽保. 相似文献

This article examines the relationship between foreign direct investment and host countries’ contracting institutions, the
rule systems which govern commercial transactions between private actors. Given their liability of foreignness and costly
exit options, we suggest that multinational corporations have incentives to influence the formal contracting environment in
host countries. Further, host governments are more likely to respond to multinationals’ wishes when they are more dependent
on foreign capital markets. We draw on the World Bank’s Lex Mundi dataset (Djankov et al. 2003) on micro-level contracting environment for private actors. Our analysis of a cross section of 98 developing countries suggests
that FDI is associated with lower contract enforcement costs, particularly when the host country is more indebted. 相似文献

Using a two stage rent-seeking framework, we present a simple model of strategic entry/terrorism deterrence and test the model using laboratory experiments. Our contest success function highlights the potential for strategic spillovers. The theory illustrates that, relative to a cooperative outcome, negative externalities lead to over-spending on deterrence and positive externalities lead to under-spending on deterrence. Our experimental results are broadly consistent; subjects in the negative externality treatment had higher expenditures. In contrast to theoretical predictions, participation decisions, while primarily driven by the probability of winning a contest, were influenced by a subject’s ability to participate in multiple contests. 相似文献

In this paper, I examine a simple procedure in the United States House of Representatives, approving the Journal, and its implications for legislative business. In this paper, I examine the hypothesis that such votes are more than simply pro forma motions or dilatory tactics by the minority party. Considering the 102nd–107th Congresses, I show that votes on the Journal’s approval are just as frequently requested by the majority party as by members of the minority party. Furthermore, I find that votes recorded on days on which a vote was also recorded on the House Journal were more likely to be close and more likely to be party-line votes than those recorded on other days. 相似文献
