十六国时期少数民族政权法制的历史影响

十六国时期少数民族所建政权的法律制度多循魏晋,但当时一些有为君主为了适应特殊情势的需要,在取舍中原汉制的基础上,又制定了一些新的法律制度,在行政、刑事、民事、经济、婚姻、司法等制度方面均有所建树,从而使十六国时期的法制在中华法制文明发展史上留下了自己的身影。     

东南亚的黑色人种及其在中国和东南亚民族史上的地位

今天东南亚的绝大多数居民属于蒙古人种,但是还有一小部分人属于另外一个种族,那就是黑色人种。今天这个种族的人数虽然不多,而且主要分布在东南亚海岛地区,但是大量的资料表明,他们很可能曾经是中南半岛的主人,甚至很可能还广泛分布于中国大陆,特别是中国南方地区。东南亚的黑     

赫哲族居住形式的变迁

居住在人类文化中占有重要的地位,对自然条件的利用,人们的经济活动、社会结构、观念、外来文化等都会体现在居住形式中。赫哲人居住形式的变迁反映了赫哲族生活质量不断提高的过程。     

从国际人权立法与实践视角探讨少数民族人权的特殊保护

对少数民族人权保护问题研究的重点,是少数民族人权的特殊保护(特殊权利或特殊保护措施)问题,但研究还十分薄弱。系统地认识国际人权立法与实践中关于少数民族人权的特殊保护,对我国少数民族人权保护有着重要的借鉴意义。本文从少数民族人权特殊保护的涵义、必要性、特殊权利、国家义务、特殊保护的限度、特殊权利的限制和克减等方面展开分析和论述。     

桥塞坐封过程仿真模拟研究

桥塞作为井下封层技术的关键设备,由于它施工工序少、周期短、卡封位置准确而得到了广泛应用。针对设计的可钻式非金属桥塞坐封过程开展模拟研究,涉及弹塑性材料接触、超弹性材料接触和非金属材料动态断裂的非线性动力学问题,利用有限元法建立该桥塞全尺寸模型和所有部件之间的广义接触关系,通过有限元模拟动态坐封过程获得桥塞各部件运动变形特性、桥塞与套管之间的密封特性和动态坐封力等数据,该桥塞坐封完成时,坐封机构部件轴向位移110 mm,坐封力约45 kN。模拟坐封也为进一步优化该型桥塞的结构和评估坐封性能提供了理论依据,对该型桥塞的推广应用奠定了基础。     

A Proportional Hazards Regression Model for the Subdistribution with Covariates‐adjusted Censoring Weight for Competing Risks Data

With competing risks data, one often needs to assess the treatment and covariate effects on the cumulative incidence function. Fine and Gray proposed a proportional hazards regression model for the subdistribution of a competing risk with the assumption that the censoring distribution and the covariates are independent. Covariate‐dependent censoring sometimes occurs in medical studies. In this paper, we study the proportional hazards regression model for the subdistribution of a competing risk with proper adjustments for covariate‐dependent censoring. We consider a covariate‐adjusted weight function by fitting the Cox model for the censoring distribution and using the predictive probability for each individual. Our simulation study shows that the covariate‐adjusted weight estimator is basically unbiased when the censoring time depends on the covariates, and the covariate‐adjusted weight approach works well for the variance estimator as well. We illustrate our methods with bone marrow transplant data from the Center for International Blood and Marrow Transplant Research. Here, cancer relapse and death in complete remission are two competing risks.     

Opportunities for woman-initiated HIV prevention methods among female sex workers in southern China

Rapid changes in China over the past two decades have led to significant problems associated with population migration and changing social attitudes, including a growing sex industry and concurrent increases in STIs and HIV. This article reports results of an exploratory study of microbicide acceptability and readiness and current HIV prevention efforts among female sex workers in two rural and one urban town in Hainan and Guangxi Provinces in southern China. The study focused on these women's knowledge and cultural understandings of options for protecting themselves from exposure to STIs and HIV, and the potential viability and acceptability of woman-initiated prevention methods. We report on ethnographic elicitation interviews conducted with women working within informal sex-work establishments (hotels, massage and beauty parlors, roadside restaurants, boarding houses). We discuss implications of these findings for further promotion of woman-initiated prevention methods such as microbicides and female condoms among female sex workers in China.

制度变迁背景下的社区权力与秩序——基于广州市一个城中村的研究

渐进的市场化和突发的制度变迁导致了城中村的权力格局和社区秩序发生了种种变化,居委会—村公司构成的权力结构及其互动关系目前已经成为城中村特有的"双轨制"权力模式,本文以广州市J社区为例深入分析这种双轨制的内在机制,认为社区内存在两种基于资源依赖基础上的循环链,由此带来了社区秩序的双重规则。
