Rib Variation at Multiple Locations and Implications for Histological Age Estimation*

Existing histological age estimation methods using the rib were developed mainly from the midshaft; however, in forensic practice, uncertainty of sampling location often arises due to fragmented or previously sampled ribs. The potential for error increases when sampling location is uncertain and utilizing a section beyond the midshaft (either anterior or posterior) may result in erroneous age estimates. Additionally, there is debate within the field regarding the minimum number of sections needed for accurate age estimation. The aim of this research is to determine the importance of the midshaft distinction for age-at-death assessment and the necessity of analyzing serial sections by evaluating histological variables at sampling locations along the length of the rib. Three seriated histological sections at three sampling locations (anterior, midshaft, and posterior) were obtained from sixth ribs of ten postmortem human subjects. Cortical area (Ct.Ar) and osteon population density (OPD) were collected from each section (n = 90). Significant differences were determined in Ct.Ar between sampling locations, demonstrating the variation present along the length of the rib. A comparison of OPD at sampling locations revealed significant differences, suggesting that sampling site is critical to accurate age estimates. When sampling location is uncertain, a more anterior section should be taken. Analysis of serial sections within locations revealed no significant differences in OPD or Ct.Ar, supporting the practice of collecting data from one section for age estimation. While an age estimate can be achieved through the analysis of one section, best practice suggests reading two sections to capture intraindividual variation.     

Gary Becker’s economics of population: reproduction and neoliberal biopolitics

This paper argues that Chicago School economist Gary Becker’s theory of fertility underpins contemporary rationalities of global population governance. Drawing on feminist critiques of biopolitics, the paper proposes reproduction as a missing link that ties Becker’s homo economicus to the aggregate question of population. It argues that Becker’s work challenged macroeconomic theories of fertility by figuring reproduction, and hence population patterns, as governed by the personal utility-maximizing decisions of individuals. It further examines how his approach to fertility inaugurated reproductive decision-making as a regulatory node of population quality, one also tied to a particular sex, race and class politics. Finally, the paper briefly analyses the relationship between Becker’s contribution and today’s focus on women’s reproductive and productive decision-making in population governance in the context of development.     

辽宁流动人口犯罪社会学分析及控制对策

流动人口犯罪是社会人口在大规模迁移流动过程中衍生的负面效应。自改革开放以来,我国在经济高速增长的同时也在经历着流动人口犯罪的高发期。辽宁省作为振兴东北老工业基地的重中之重,随着外来流动人口数量的逐年增长,外来流动人口的犯罪形势亦日趋严峻,根据社会学的方法论原则,来系统分析辽宁外来流动人口犯罪的基本特征、形成原因以及流动人口管理中存在的问题,是科学制定综合治理控制对策的前提和基础。     

辽宁流动人口犯罪现状分析

在市场经济发展的今天,人口流动呈现出必然趋势。这其中蕴含着一定的规律和特点。伴随着人口流动的规律特点,流动人口犯罪也具有一定的规律性可循。本文在对辽宁流动人口状况调查研究的基础上,提出了辽宁流动人口犯罪的规律特点,藉此希望能为政府有关部门决策提供参考。     

经济发达地区的出租屋管理模式及法律问题思考

在经济发达地区，外来人口已经分化成为外来常住人口和外来流动人口。外来常住人口的工作和居所比较固定，相对来说配合管理。而外来流动人口则相对流动性较大，工作和居所不固定。除住在宾馆、旅社、招待所外他们一般以城乡结合部的农民或“城中村”的居民住房改造成的出粗屋为居所。在经济发达地区外来流动人口和出租屋事实上已经形成了独立的场所。因此，针对外来流动人口一般以出租屋为落脚点，政府对出租屋的管理应象对娱乐场所管理一样引起重视，要予以单独立法，确认出租屋管理行政合同制，并努力用最先进的现代化管理手段来提高管理效率。

中国人群补体C_1R的遗传多态性

采用聚丙烯酰胺等电聚焦电泳，结合免疫印迹技术，对中国辽宁地区360名无关个体的补体C1R遗传多态性进行了研究。共检出6种常见表现型和4种变异型。基因频率C1R*1=0．5181，C1R*2=0．3291，C1R*3=0．1472，CIR*R=0．0056，分布符合Hardy-Weinberg法则。C1R的血型鉴别机率（DP值）为0．7694，是一种具有高度鉴别能力的血清多态性遗传标记。
