经济增长、社会发展与男孩偏好:基于治理的视角

本文基于1990、2000年全国人口普查数据和1995、2005年全国1%人口抽样调查数据,采用了多层线性模型(HLM)方法,对经济增长、社会发展和男孩偏好之间的关系进行了分析。发现较高的经济增长水平和社会发展程度有助于出生人口性别比治理绩效的实现,但受到男孩偏好强弱程度的影响。论文结尾分析了研究结论对于出生人口性别比治理的政策启示,并指出了局限性和未来改进方向。     

Where Registered Sex Offenders Live: Community Characteristics and Proximity to Possible Victims

Recent developments in sanctions for sex offenders emphasize use of sex offender registries and residential restrictions in efforts to raise public awareness and keep offenders away from possible victims. One consequence of such efforts is to relegate registered sex offenders to socially disorganized communities. The present study draws on census tract level data from one urban county and assesses whether offenders are likely to be found in socially disorganized communities and in communities with high concentrations of potential victims. Findings show that registered sex offenders are more likely to reside in socially disorganized and disadvantaged communities, but not in locations with large pools of most types of possible victims (e.g., women living alone, children). Residential location is explained in terms of economic factors, not desire to live near possible victims. Implications for current policies and practices are discussed.     

我国证券市场内幕交易的民事责任制度之初探

在我国证券法中,只重视对证券发行和交易的管理以及违反证券行政管理导致的行政、刑事法律责任的规定,忽略了对证券交易当事人之间的民事权利义务关系以及对民事权力侵害救济的关照。参照世界各国证券内幕交易的民事救济手段,我国也应完善证券内幕交易的民事责任制度,以最大程度地保护投资者的利益,从而进一步健全我国的证券市场。     

Structural discrimination and social stigma among individuals incarcerated for sexual offenses: Reentry across the rural–urban continuum

The stigma associated with a felony conviction can impede the reentry process, and emerging research findings indicate that one's community can amplify or temper the mark of a criminal record. Researchers examining criminal stigma have focused on individuals living in urban areas, overlooking the experiences of persons outside these communities. Using qualitative data collected from a sample of men and women paroled for sexual offenses in Missouri, we contrast how social and structural stigma alter the reentry experiences for participants living in communities along the rural and urban continuum. The results show that the stigma of a sex offense conviction was a near‐universal experience and residence restrictions stymied efforts to find housing. Residents of urban areas and some large cities felt that the community offered relative anonymity from stigma but the stress of their status being discovered was omnipresent. Participants in rural areas and small cities had less social privacy and reported being shunned in the community, although strong social ties did mitigate some of the consequences of stigma. The results highlight the importance of considering place when studying reentry and have implications for designing correctional policies to address the needs of residents returning to non–metropolitan locations.     

A Pimp's Game: A Rational Choice Approach to Understanding the Decisions of Sex Traffickers

We employ a rational choice framework to understand the conditions under which sex traffickers allow their victims access to telecommunications devices while under their control. We posit that sex traffickers are rational actors who make calculated decisions regarding whether to allow their victims access to the Internet and cell phones. We hypothesize that sex traffickers allow younger victims and those they did not defraud in the recruitment process greater access to telecommunications devices because these decisions maximize their payoffs with minimal risk. However, we hypothesize that younger victims’ access to telecommunications devices is conditional on whether they have been defrauded in recruitment. In order to test these hypotheses, we deployed a survey to 115 victims of sex trafficking in the United States to learn about how they were recruited by their sex trafficker and the level of access they had to technology while under their sex trafficker's control. We find support for all of our hypotheses. The results have serious implications for criminal justice policy and practice.     

“A different world” exploring and understanding the climate of a recently re-rolled sexual offender prison

Understanding how sexual offenders experience prison and its environment is important because such experiences can impact on rehabilitation outcomes. The purpose of this research investigation was to explore the rehabilitative and therapeutic climate of a recently re-rolled sexual offender prison. The research took a mixed methods approach and consisted of quantitative and qualitative phases. There were differences between prisoners and staff on their perception of the prison climate and for prisoner and staff relationships. The qualitative results helped to explain the quantitative findings and added a more nuanced understanding of the experience of the prison, the nature of prisoner and staff relationships and the opportunities for personal growth within the prison. The study has important implications for prisons that co-locate sexual offenders and want to provide an environment conducive to rehabilitation.     

“Kind regards”: an examination of one buyer's attempt to purchase a trafficked child for sex

A call to awareness regarding sex trafficking has increased research, bolstered social justice efforts, improved education, and influenced federal laws that protect victims and prosecute traffickers. Federal laws on sex trafficking are now being used through undercover sting operations via the Internet to arrest and prosecute buyers who attempt to engage in commercial sex with minors. A narrative analysis was completed to create an in-depth case study outlining the correspondences between a buyer and an undercover agent advertising trafficked children for sex. Readers are afforded a rare opportunity to examine actual emails related to the purchase of a child for sexual exploitation. The emails were used against the buyer as evidence within the court of law. The authors assert that the following case study will contribute to the body of literature on the victim selection processes and cognitive distortions employed by buyers of children for sex.     

The Competition–Violence Hypothesis: Sex,Marriage, and Male Aggression

Sexually active men, who are not in a monogamous relationship, may be at a greater risk for violence than men who are sexually active within monogamous relationships and men who are not sexually active. The current study examines changes in sexual behavior and violence in adolescence to early adulthood. Data on male (n = 4,597) and female (n = 5,523) respondents were drawn from four waves of the National Longitudinal Study of Adolescent and Adult Health (Add Health). HLM regression models indicate that men who transition to a monogamous, or less competitive, mode of sexual behavior (fewer partners since last wave), reduce their risk for violence. The same results were not replicated for females. Further, results were not accounted for by marital status or other more readily accepted explanations of violence. Findings suggest that competition for sex be further examined as a potential cause of male violence.     

抵押证券制度结构论--以德日抵押证券模式为背景

作为权利与证券相结合的一种形态 ,抵押证券表现为两种类型 :一为德国模式 ;二为日本模式。纵观德日两国抵押证券模式 ,抵押证券在制度结构上分为两部分 :其一为抵押证券的发行 ;其二为抵押证券的交易。抵押证券的发行涉及到抵押证券的交付申请人、抵押不动产的评价等方面内容 ,抵押证券的交易涉及到抵押证券的贩卖方式、抵押证券的流通性确保等方面问题。我国将来如推行抵押证券制度 ,也必然会牵涉到抵押证券这些方面的内容。     

牦牛子宫内膜细胞的分离培养及性激素对其增殖的影响

为了分离培养牦牛子宫内膜细胞,并探讨不同浓度雌激素和孕激素对上皮细胞和基质细胞增殖的影响,采用Ⅰ型胶原酶消化、离心分离和差速消化纯化的方法分离纯化上皮细胞和基质细胞,对其进行免疫细胞化学染色鉴定,绘制生长曲线,最后用MTT法测定不同浓度的17β-雌二醇和孕酮对细胞增殖的影响。结果显示,1g/L胶原酶消化1h,500r/min离心10min,经2代差速消化纯化获得的上皮细胞的纯度为96%,基质细胞的纯度为93%;不同浓度的17β-雌二醇均能促进上皮细胞和基质细胞的增殖,孕酮可促进基质细胞的增殖,但对上皮细胞的增殖有抑制作用,不同浓度的17β-雌二醇和孕酮共同作用均能显著促进基质细胞增殖,而对上皮细胞增殖的影响随混合液中孕酮浓度的增加由促进转为抑制。本研究获得了高纯度的牦牛子宫内膜上皮细胞和基质细胞,证实雌激素能促进2种细胞的增殖,孕激素能促进基质细胞的增殖但抑制上皮细胞的增殖。
