DELINQUENCY AND GENDER MODERATION IN THE MOVING TO OPPORTUNITY INTERVENTION: THE ROLE OF EXTENDED NEIGHBORHOODS

A long history of research has indicated that neighborhood poverty increases youth's risk taking and delinquency. This literature predominantly has treated neighborhoods as independent of their surroundings despite rapidly growing ecological evidence on the geographic clustering of crime that suggests otherwise. This study proposes that to understand neighborhood effects, investigating youth's wider surroundings holds theoretical and empirical value. By revisiting longitudinal data on more than 1500 low‐income youth who participated in the Moving to Opportunity (MTO) randomized intervention, this article explores the importance of extended neighborhoods (neighborhoods and surroundings) and different concentrated disadvantage configurations in shaping gender differences in risk taking and delinquency. The results from two‐stage, least‐squares analyses suggest that the extended neighborhoods matter and they matter differently by gender. Among girls, extended neighborhoods without concentrated disadvantage were associated with lower risk‐taking prevalence than extended neighborhoods with concentrated disadvantage. In contrast, among boys, localized concentration of disadvantage was associated with the highest prevalence of risk taking and delinquency. Interactions between the immediate and surrounding neighborhoods were similarly associated with differential opportunity and social disorganization mediators. Among the more critical potential mediators of the link between localized disadvantage and boys’ risk taking were delinquent network ties, strain, and perceived absence of legitimate opportunities for success.     

亨利·列斐伏尔的社会空间理论

社会空间是一种社会性的产品,空间产品相对过剩会产生经济危机。空间实践、空间表述、表述空间构成社会空间的三元辩证组合或者三元辩证法,第三项不是前两项的简单叠加,而是对它们所假定的完整性进行拆解和重构之后,形成的一种开放的选择项。社会空间包含着复杂的符号体系,空间三元组合类似于符号学的能指、所指、意指三项组合。身体是社会空间的生产主体,社会空间的生产从身体开始,处于异化状态的身体受权力、符号、知识三位一体控制。只有生产出社会主义差异空间,身体才能获得完全解放。当前全球经济危机的实质是城市化危机,中国正处于城市化危机的起始阶段。     

关亏物权法中空间权若干问题的探讨

空间权作为一种新型的权利,随着对土地立体开发的繁荣而越来越受到关注。许多国家对此进行了相关或专门的立法,然而,我国对空间权的研究和立法较为滞后。文章主要从目前国内外空间权的立法概况、空间权体系构成、空间权的客体、性质等几个方面作一些探讨。     

固定形式印刷品广告发展现状及趋势

在我国固定形式印刷品广告的发展基本上可分为两个阶段:一是兴起阶段,二是发展阶段。无论是兴起阶段还是发展阶段,固定形式印刷品广告都呈现出良好的发展前景,但也存在不少问题。固定形式印刷品广告低廉的成本及极强的针对性、亲切感和真实性,必将受到企业经营者的青睐,具有一定的市场发展空间和生存环境。     

空间碎片造成空间环境污染的国际责任

空间碎片是人类发射空间实体在外空留下的太空垃圾,其造成空间环境污染是一特殊种类的环境污染问题.空间实体发射国在外空留下空间碎片违背了其应承担的国际法义务,在外空的空间碎片无法辨认其归属的情况下,清扫外空的空间碎片和预防产生新的空间碎片应该是国际社会所有的空间实体发射国的共同国际责任.     

Terror in the Texts: Technology – Law – Future

This paper is concerned withlaw's failure and need to manifest theessentiality of technology for the West. Thiswill be shown through a critical reading of therelated fictional and juridical projects ofAmerican golden age science fiction and spacelaw. This analysis involves sensitivity to theterrors that bind together technology, law andthe future. It is argued that cornucopia, thevictory of modernism through technology, ispresented in science fiction and space law asterrorised by its other – dystopia. Thisterrorising means that cornucopia activelyresists dystopia. However, this resistiveenterprise is flawed – cornucopia never escapesdystopia. Alternative images of humanity andtechnology are needed to escape these flawedimaginings of the West. The paper concludesthat the cyborg offers the potential for aregenerative thinking about technology and law.     

转型后俄乌两国经济联系探析

苏联时期俄罗斯与乌克兰两个加盟共和国间的经济联系是一个有机的整体，苏联解体后，俄乌转变为两个相互间有着内在紧密联系的独立国家。由于乌克兰特殊的地缘经济政治地位，与欧洲经济一体化也同样是乌克兰优先发展的对外政策，在政治因素的影响下两国在能源、农产品和军工领域的合作进程发展缓慢。从长远来看，发展两国间的内在经济联系，促进两国间多领域合作是符合两国经济发展共同利益的方向。     

大卫·哈维“时空修复”理论的建构与考量

大卫·哈维作为新马克思主义城市理论的代表人物一直以敏锐的观察力和独特的视角而著称,他提出的"时空修复"理论以历史唯物主义空间理论为切入点,通过案例分析与政治经济学的解读阐释了空间视域的重要价值,分析了时间推移与空间扩张、地理重组是当代资本主义处理过度积累和经济危机的重要方式。"时空修复"理论的建构与发展有着深刻的时代背景和重要的学术研究价值,对其进行深入研究对我们分析全球化时代的世界局势和中国发展道路提供了重要的借鉴。但"时空修复"理论也有一定的局限性,需要辨识与思考。     

顶空GC／MS法检验血液中的硫化氢

目的建立血液中硫化氢的气相色谱质谱联用分析方法。方法取心血3mL-5mL,置于20mL顶空瓶中,加入1g氯化钠,加3mL-5mL蒸馏水,加入2mol／L盐酸1mL,加盖密封,混匀后于80℃水浴中加热20min。取液上气体0．5mL进样分析。结果在中毒死亡者的心血中检出硫化氢,保留时间参考值为3．6min。结论该方法可用于刑事案件中硫化氢的快速分析。     

台湾外省第二代家族书写研究

近年,台湾的认同问题越发引起关注。面对父辈的衰弱与消亡,外省第二代作家张大春、骆以军、陈玉慧等纷纷介入家族小说的创作,企图以文字为"我族"保存记忆与建构认同。他们有着相似的关怀与焦虑,但外省族群内部并非铁板一块。本文旨在厘清外省第二代作家近期小说中的家国想象与族群建构,同时论述空间地景与文化记忆所彰显的多音交叠的差异性认同取向。
