Residential mobility and the onset of adolescent sexual activity

Data from almost 5,000 adolescent respondents to the National Longitudinal Study of Adolescent Health (Add Health) are used to examine the mechanisms that transmit the facilitative effect of residential mobility on the timing of the transition to first premarital sexual intercourse. Adolescents who have recently moved are approximately one third more likely than nonmobile adolescents to experience first premarital intercourse between the first two waves of Add Health. We find that much of the difference between adolescent movers and stayers in the onset of sexual activity is attributable to the greater propensity for delinquency and the weaker academic performance among members of movers’ school‐based friendship networks. Adolescents’ own delinquent behavior and academic performance also help to mediate the association between residential mobility and the transition to first intercourse.     

The Effect of Decisions About Spent Nuclear Fuel Storage on Residential Property Values

National, regional, state, and local surveys have revealed that people have intensely negative images of "nuclear" and "radioactive" technologies, activities, and facilities, as well as associated fears of stigmatization. In light of these perceptions, the debate over where to temporarily store or permanently dispose of spent nuclear fuel (at the reactor site, an interim storage facility, or a permanent repository) provokes immense concern among possible host jurisdictions. To address these concerns, one needs to know if people's subjective opinions conform with the choices they make and are therefore reflected in their economic behavior. Argonne National Laboratory researchers used a hedonic model to complete a study of residential property value dynamics over a 5-year period within a 15-mile radius of two California nuclear power plants. They tracked the economic ramifications of decisions about the spent nuclear fuel stored at those reactors. The study revealed that no significant negative effects on residential property values resulted from a decision to move spent nuclear fuel from wet storage to a dry-cask storage facility or from a request to extend the reactor operating permit (given future changes in the type of nuclear fuel storage facility that would accompany such an extension).     

人体安全意象的表达——居住空间生成的原型

居住空间的原型起源于人类维护人体安全的防卫意识,这种防卫意识可以用一个人体维护结构图式表达。人的生存空间只有与这个结构形式相吻合,人在其中才会有一种真正的、心理上的安全感与舒适感；同时,人类自己也在不断用这个结构衡量和判断周围环境,并以此为依据来选择或屏蔽外界信息。这种发乎“人体安全意象”的安全观念的表达是人类居住空间生成的原型,也是人类生存居住的理想模式。     

经济发展与主观生活质量--以北京、上海、广州为例

对我国经济发达地区的北京、上海、广州三城市居民生活满意度进行比较研究,以三城市居民的问卷调查资料为基础,比较分析了三城市居民主观生活满意度的差异以及个人月收入与生活满意度之间的关系.研究发现,上海居民满意度最高,广州其次,而北京最低;同时还发现,在经济发达地区的个人月收入对生活满意度影响程度不如想象的那么大,人均GDP与生活满意度的关系值得进一步探讨.     

新中国50多年来宅基地立法的历史沿革

宅基地立法是宅基地法制建设的重要组成部分.根据土地制度演变与土地管理体制演变,可将宅基地立法分为宅基地私有时期的立法、人民公社时期的宅基地立法、改革开放初期的宅基地立法、城乡土地统管阶段的宅基地立法、城乡土地体管理制转轨阶段的宅基地立法等五个阶段;不同的发展阶段具有不同的立法内容,不同的立法内容具有不同的特点.     

居住格局对民族关系的影响及对策研究——以西宁市城东区为例

西宁市城东区作为青海回族、藏族、土族、撒拉族、蒙古族等少数民族聚居的典型区域，在居住格局上形成了“混合社区”、“聚居社区”、“过渡社区”三种模式，这种状况造成了不同民族之间实际感情距离的疏远，进而对民族关系的正常发展产生了很大的影响；提出解决问题的基本对策，对改善和解决城东区的复杂民族关系提供决策参考。

Residential Segregation by Race and the Black Merchants of Northern Cities During the Early Twentieth Century

During the early 20th century, many Blacks in northern cities entered the retail trade, supposedly because residential segregation was advantageous to Black merchants. Building upon historical studies of Blacks in the urban North and upon the sociological literature on Black business enterprise, I use census data to analyze the relationship between (1) the spatial isolation of Blacks and (2) the representation of Blacks in the retail trade. I find that between 1900 and 1930 the association between these two variables became significantly positive. This finding corroborates historical case studies, and I conclude that after segregated Black communities emerged in northern cities at the end of the study period, spatial isolation did increase the participation of Blacks in the retail trade.     

Safeguarding disabled children in residential settings: what we know and what we don't know

Research in America, Canada, Australia and Britain has revealed that disabled children are particularly vulnerable to abuse. Their likelihood of attending residential institutions, their dependency on others for personal care and the lack of opportunities for them to alert others to maltreatment or comprehend the nature of abusive acts all increase levels of risk. Over the last decade, there has been increasing public and professional concern about the abuse of children in residential establishments, resulting in a number of inquiries. However, the abuse of disabled children in residential settings has received little attention. Despite residential schools, care homes and respite care being widely used by disabled children, there is a paucity of knowledge regarding the standards of child protection in these establishments. This article explores the research literature revealing the vulnerability of disabled children to abuse when living away from home, what measures can be taken to help protect them and the limitations of available data as a basis for planning child protection measures.
