Becoming Custodial Dads: Exploring Parenting Among Low‐Income and Working‐Class African American Fathers

The authors use an ecological framework and grounded theoretical analysis to explore the circumstances in which working‐class and low‐income custodial African American fathers gain custody of their children, their transition from part‐time to full‐time parents, and the role of support networks in enhancing or inhibiting these men's parenting. Twenty‐four men from an impoverished Midwestern urban area participated in the study. The findings suggest that these men, and perhaps others sharing their demographic profiles, generally become parents by default and are often reluctant to take on a full‐time, single parenting role. Adaptation to the role seems to be enhanced by these men's use of extended kin support networks and shared living arrangements. However, low wages, a lack of sufficient assistance from public assistance programs, and informal custody arrangements often inhibit their fathering.

《孟子》中的单音节形容词研究

文章主要从量的角度对《孟子》中的单音节形容词的句法功能进行研究,通过与现代汉语形容词的特征比较,结果发现单音节形容词作谓语(不带宾语),单音节形容词作宾语,单音节形容词带宾语以及单音节形容词作定语是《孟子》中的单音节形容词的重要特征。     

Determinants of housing quality: A comparison of white,African-American,and Hispanic single-parent women

This study examines housing quality among three groups of single-parent women: white, African-American, and Hispanic. Three indicators of housing quality—crowding, affordability, and satisfaction—are used to discover the extent to which these groups experience housing problems. This study also explores differences and similarities in the factors that precipitate problems in housing quality for these three groups of single parents. Findings suggest important differences and similarities in the nature of housing quality problems among white, African-American, and Hispanic single-parent women. The specified variables explained about 20% of the variance in crowding, housing affordability, and housing satisfaction. On measures of objective and subjective housing quality, white single mothers are better housed than their African-American or Hispanic counterparts. Hispanic single mothers have the largest housing cost burden and average more persons per household than the other groups. African-Americans are twice as likely as either group to live in low-quality housing and reported the lowest average satisfaction with their housing. Her research interests include housing and neighborhood assessment and women and public policy issues. She has recently published articles inUrban Affairs Quarterly andHousing and Society on housing and neighborhood assessment criteria among black urban households and the housing cost burden of various groups of female-headed households. She received her Ph.D. from Ohio State University. Her research interests include the housing adjustment behavior of women and public policy. She has recently completed her thesis on the role of noncustodial parents in determining the quality of life of their children. She is also the recipient of the Tessie Agan Award for research excellence from the American Association of Housing Educators for a paper titled “Unterstanding Constraints and Residential Satisfaction among Low-Income Single-Parent Families.”     

论拉伦茨氏裁判方法的实质

使用传统的判案理论系统分析了拉伦茨氏的方法论体系。指出，拉伦茨氏方法论的基础是欧洲传统“名判”逻辑，其设定目标乃个案公决。拉伦茨氏强调了法官“续造法”的权力。所续造的“法”不是条法，而是曾经自主运用诸条法的模式，它理应有“现行法”的拘束力。“条法库”的缺漏由审判员以法律运用技术补足。诸准则之不谐或与宪法条法的不谐需赖“法益衡量”调谐。分析结论是，拉伦茨氏片面突出法官的自主地位，其方法论在本质上是现代法治社会一种尚需调制的折衷系统。     

维吾尔语主位结构与句子主语关系研究

以韩礼德和汤普森关于主位结构的理论为依据,分析维语各种语气结构中的主语和单项主位的关系,发现维语主语在多数情况下充当无标记性主位,主语和主位的重合在陈述句中最为明显。但是,维语主语有时也可以充当无标记性述位。     

粮食产量时间序列的单分形检验及R/S预测

为探讨中国粮食产量的变化规律及趋势预测问题,采用配分函数方法,判定了1949年以来粮食总产量时间序列的单分形特征,并利用分析方法确定一个代表粮食产量变化趋势的时间序列的幂,从而得到预测粮食产量变化趋势的分形方法。根据历史资料,用此方法对中国粮食产量的变化趋势进行了短期预测,得到了变化方向上的一个估计结果。     

A relation for the covariances of order statistics from n independent and non-identically distributed random variables

We derive a simple relation satisfied by the covariances of order statistics in the i.i.d. case and then generalize it to the case when the variables are independent and non-identically distributed. This relation could be employed successfully either to check the calculations or to reduce the amount of direct computations involved in evaluating the covariances of order statistics from an outlier model.     

中国单身女性的困境: 多元交叉的社会压力和歧视

随着中国单身人口比例的上升,单身人群特别是单身女性群体受到了社会各个层面的关注。目前国内对单身女性的研究主要通过深度访谈来探讨单身未婚女性的身心和生活状态,缺乏系统的理论观照,且访谈样本又大都局限于大城市的中产阶层单身未婚女性,因而限制了研究成果的代表性。从交叉性理论出发,分析中国单身女性面临的宏观(儒家文化和人口调控压力)、中观(媒体的形象控制和代际压力)和微观(性别歧视、年龄歧视和单身歧视)的多元交叉压力和歧视,厘清目前单身女性所受到的压力和歧视,从不同阶层单身女性的需求出发,才能为她们提供切实有效的帮助,并有助于解决目前我国单身人口比例上升的问题,缓解人口老龄化的压力。     

An Individual Mixed‐Evaluation Method for Career Intervention

Economic issues linked to career counseling are a cause for concern to policy makers in developed countries because they expect career practitioners to provide evidence of the efficiency of career counseling interventions. The aim of this study was to test an individual evaluation method mixing time series (outcomes) and life narrative (processes). The method used 5 items related to 1 client's career decision self‐efficacy and studied the evolution of those items throughout the intervention of 1 career counselor (43 days). Changepoint analysis helped in identifying the changes that have to be taken into account for time series and which are contextualized in the client's verbatim analysis. This mixed method highlighted that the career counselor's intervention increased the client's career decision self‐efficacy. Practitioners could use the methodology proposed in this article to evaluate their interventions. They could also report their practice to clients, employers, and decision makers.
