Intimate Violence in Lesbian Relationships

This paper describes the findings of a survey of 1109 lesbians who attended the Women's Music Festival held in Michigan in carly August 1985. The primary objectives of the study were to document the incidence of domestic violence in a non-random sample of lesbian relationships; to identify and describe the types of domestic violence experienced and/or perpetrated; and to ascertain thc availability and accessibility of community helping resources to survivors and perpetrators after an abusive episode. Comparisons with domestic violence in heterosexual relationships are also made, followed by a discussion on the research and practice implications of the findings.     

传统性别分工对选用女性干部的影响——基于湖南省某市两次干部考试的思考

当今各级政府干部选用,性别因素在一定程度上起着一定作用,从而导致女性参政处于不利地位。究其原因最为关键的是传统性别分工所带来的影响所致,这种影响主要表现在两个方面：一是它导致了性别刻板角色的形成;二是它强化了带有偏见的社会性别文化。     

关于建立城乡统一的社会保障体系的浅见

建立城乡统一的社会保障体系不仅是学术界争论的焦点，也是实践部门讨论的热点。各种主张众说纷纭。然而，建立统一的社会保障体系不能凭空设想，应立足于实际，坚持具体问题具体分析。当务之急是根据农村的情况，分地方、分人群、分层次建立安全有效的农村社会保障体系。     

Meeting myself: race-gender oppression and a genre study of Black men teachers’ interactions with Black boys

ABSTRACT

Increasing the number of Black men teachers and single-sex schooling options have been heralded as necessary to reverse trends in the failure of US education institutions to adequately educate Black boys. Too little research interrogates Black men teachers’ interactions with Black boys for how they might reinforce anti-oppressive conceptions of race, gender and sexuality. A genre study – the multidimensional, intersectional examination of social identity to explain one’s persistent dehumanization – was utilized to investigate how Black men teachers’ interactions with Black boys shape the boys’ understanding of Black manhood and masculinities. Regardless of schooling arrangement, findings suggest Black men teachers must recognize and disavow hegemonic gender logics in interaction efforts aimed at improving Black boys’ lives. Additionally, I argue the potential of Black men teachers’ interactions with Black boys to function as sites for reimagining Black boys’ humanity in ways that counter persistent messages of their inferiority and disposability (i.e. aniblackness).     

岷江上游干旱河谷区生态屏障体系建设研究

自动化立体仓库中出入库任务顺序与出库位置选择集成优化研究

具有多个出口的自动化立体仓库系统是一种将存储和分拣相结合的新型仓储技术,其最典型的特征是在货架底层有很多个出库位置以供取货人员分拣。研究此系统中出入库任务排序与出口选择的集成优化问题,以最小化堆垛机完成所有任务的移动距离为目标,将此问题转化为一个混合整数规划模型。根据问题的特点设计了两阶段启发式算法求解此问题,数值结果表明设计的算法能在较短时间内给出近似最优解,同时与企业常用的先到先服务方法相比,该算法可以缩短超过20%的移动距离。     

公司治理对会计信息披露质量影响 ——基于我国生物医药业上市公司的实证研究

会计信息披露是企业向信息使用者揭示和反映企业价值运动,高质量的信息披露可以降低信息不对称程度,使投资者能更正确地做出判断.以生物医药业上市公司为例,采用Logistic回归分析方法,系统研究公司治理与会计信息的披露质量之间的关系,发现公司治理中的董事会规模、独立董事比例和监事会规模的提高会使得会计信息披露质量得到提高,董事会会议次数与会计信息披露质量显著负相关.

Exploring Parameter Relations for Multi‐Stage Models in Stage‐Wise Constant and Time Dependent Hazard Rates

Single cohort stage‐frequency data are considered when assessing the stage reached by individuals through destructive sampling. For this type of data, when all hazard rates are assumed constant and equal, Laplace transform methods have been applied in the past to estimate the parameters in each stage‐duration distribution and the overall hazard rates. If hazard rates are not all equal, estimating stage‐duration parameters using Laplace transform methods becomes complex. In this paper, two new models are proposed to estimate stage‐dependent maturation parameters using Laplace transform methods where non‐trivial hazard rates apply. The first model encompasses hazard rates that are constant within each stage but vary between stages. The second model encompasses time‐dependent hazard rates within stages. Moreover, this paper introduces a method for estimating the hazard rate in each stage for the stage‐wise constant hazard rates model. This work presents methods that could be used in specific types of laboratory studies, but the main motivation is to explore the relationships between stage maturation parameters that, in future work, could be exploited in applying Bayesian approaches. The application of the methodology in each model is evaluated using simulated data in order to illustrate the structure of these models.
