A teacher’s journey: a first-person account of how a gay,Cambodian refugee navigated myriad barriers to become educated in the United States

Educational institutions, like most social service organizations, need to recognize intersectionality and complexity and move away from monolithic conceptions of homelessness – if they recognize homelessness at all. This first person account of a gay, Cambodian refugee illustrates the enormous complexity schools face in forming institutional responses for the needs of homeless, highly mobile, and economically displaced children and youth. This article demonstrates an effort to avoid reductionist definitions of homelessness and to include experiential representations of humans living at the margins (under the 5th Avenues of the world, in central parks, in downtown shelters, outside of the ethical and systemic “home” of current ideologies and social orders, under the politics of HIV in Africa, as refugees and as those “othered” by dominant social narratives). The research takes place in the context of the At Home At School program at Washington State University.     

Impacts of social economic status on higher education opportunity and graduate employment in China

Based on a nation-wide survey of higher education graduates, this paper analyzes the impact of family background, using paternal occupation and education as indicators, on their scores in the National College Entrance Examination, the level and type of higher education institutions they attend, their employment after graduation, and the income they receive from their first job. It has been found that there are wide disparities among students with different family backgrounds in both access to higher education and their potential employment in China nowadays. This paper also studies how those influences happen. __________ Translated from Peking University Education Review, 2005 July (3)

刑事诉讼电子证据的关联性问题研究

电子数据是2012年《刑事诉讼法》所规定的独立证据种类,可以用于证明案件事实的电子数据被称为电子证据。在实际司法实践中,立法的缺失、理论研究的不足以及技术手段的不成熟,导致电子证据存在大量关联性认证困难的问题。以类案分析和个案探讨相结合的方式,重点对电子证据的关联性问题展开分析论述,并提出可操作性建议,以期充分实现电子证据在新时期违法犯罪活动中的最大价值。

单核细胞增多性李斯特菌RsbR抗酸应激机制（英文）

目的:探明单增李斯特菌RsbR的两个保守磷酸化位点是否影响SigB(sigmaB)的表达.创新点:解析了RsbR在单增李斯特菌中SigB网络调控中的作用.方法:通过基因缺失、定点突变和回补技术构建rsbR基因缺失株、回补株和回补突变菌株,进行酸应激条件下的生长能力和强酸条件下的存活能力试验,并检测在酸应激下菌株中的SigB基因和蛋白表达的改变情况.结论:RsbR缺失能够显著降低单增李斯特菌的抗酸应激能力和下调SigB表达,RsbR-175位点是SigB调控途径中RsbT释放的先决条件.
