Towards a sociology of risk work: A narrative review and synthesis

In this article, we define the concept of “risk work,” which aims to make visible working practices to assess or manage risk, in order to subject these practices to sociological critique. This article reviews and synthesizes existing published literature to identify components of risk work: (a) translating risk into different contexts, (b) minimizing risks in practice, and (c) caring in the context of risk. We argue that these three components of risk work raise important tensions for workers that have been inadequately explored in the literature to date. We propose that future research should additionally focus on practitioner subjectivity and identity in risk work. In addition, we argue that comparative research—across type of risk and different contexts—and methodological and theoretical diversity would enhance this emerging field of research.     

“I'm Not Supporting His Kids”: Nonresident Fathers' Contributions Given Mothers' New Fertility

The authors examined whether nonresident fathers provide informal support to their children and whether support stops if their ex‐partner goes on to have a child with a new man. A logistic regression analysis of longitudinal survey and administrative data for 434 women who received welfare in Wisconsin showed that fathers are less likely to provide informal support when their ex‐partner has a child with a new partner. Alternative models that control for unobserved characteristics suggest somewhat different results, providing stronger evidence of declines in support that can be shared across family members than in support that can be directed to a particular child.     

A Qualitative Study of Middle Eastern/Arab American Sexual Minority Identity Development

The development of one's sexual minority identity is often stunted by a heterosexist society. For individuals with multiple minority oppressions, this process becomes even more complicated. As such, there has been a call among researchers for more empirical research on the experiences of lesbian, gay, bisexual (LGB) individuals from racial/ethnic minority groups. This study uses qualitative methods to fill gaps in the literature related to identity development among same-gender attracted Middle Eastern/Arab individuals living in the United States. From 12 interviews, 13 themes associated with intersectionality, race/ethnicity, sexual identity development, discrimination, stigma, oppression, and invisibility. Themes, subthemes, and their implications are discussed.     

论汉代政权对民间信仰的多重政策

民间信仰是中国传统文化的重要组成部分,也是俗文化的核心。针对民间自发形成的信仰与崇拜,汉代政权采取多重政策,或引导支持,或借鉴利用,或排斥打击,主要取决于其是否与官方信仰及主流文化相抵触,是否从根本上影响到社会秩序和百姓生产生活。不管官方态度如何,作为一种强大的民间力量,民间信仰以其特有的方式参与政治生活,与官方政权相互影响、相互补充,形成既配合又抗衡的互动局面,并以顽强的生命力传承、延续和发展。     

多元智能理论在《思想道德修养与法律基础》课教学中的应用

多元智能理论认为,人的智能是多元的,每个正常的人都在一定程度上拥有其中的多项技能,人类个体的不同在于所拥有的技能的程度和组合不同。借鉴这一理论,有利于充分发挥高职院校《思想道德修养与法律基础》课的思想政治教育作用,形成科学的教学观、学生观、师生观和评价观,促进学生的全面发展,增强教学实效性,提高教学质量。     

基于高维分步投影的多重分区聚类算法

数据分布密度划分的聚类算法是数据挖掘聚类算法的主要方法之一。针对传统密度划分聚类算法存在运算复杂、运行效率不高等缺陷，设计高维分步投影的多重分区聚类算法；以高维分布投影密度为依据，对数据集进行多重分区，产生数据集的子簇空间，并进行子簇合并，形成理想的聚类结果；依据该算法进行实验，结果证明该算法具有运算简单和运行效率高等优良性。     

全球化背景下的中国现代性建构

全球化并不预示着一个全球大同时代的来临，反而在很大程度上表现了文化之间的差异性甚至对抗性。在这样的时代背景下，对于各民族文化尤其是对非西方社会来说，如何理解现代性与追求自身的现代化，成为一个紧迫的任务。在中国现代性的建构过程中，既要求加深对现代性的理解，也要求更好地把握自己的文化传统。     

岩体变形参数的应力状态效应研究

岩体力学参数存在随应力状态不同而变化的特性，称为应力状态效应。岩体力学特性的实测值具有空间场分布特征，分析表明地应力（或围压）的有规律变化是造成岩体力学参数空间变化的主要原因。考虑到实测地应力多具有较大的离散型，尝试利用反演方法获取地应力场信息，通过多元回归分析得到实测岩体变形参数与地应力的经验关系，以研究岩体变形参数的应力状态效应。通过一工程实例研究：得到地下厂房区域的岩体变形模量为16 GPa左右，与反演分析结果也比较符合；通过应力状态效应研究得到的岩体变形参数物理场，是一个渐变的物理场模型，是更为符     

高校图书馆构建重点学科文献保障体系的策略

文献资源建设是重点学科建设的重要组成部分。高校图书馆要深入了解重点学科的发展现状和趋势,探索重点学科对文献资源的需求特点,从文献资源类型、内容、形式等方面入手,构建满足重点学科需求的文献保障体系,为重点学科建设提供强有力的支持。     

Using multiple imputation to estimate cumulative distribution functions in longitudinal data analysis with data missing at random

In longitudinal clinical studies, after randomization at baseline, subjects are followed for a period of time for development of symptoms. The interested inference could be the mean change from baseline to a particular visit in some lab values, the proportion of responders to some threshold category at a particular visit post baseline, or the time to some important event. However, in some applications, the interest may be in estimating the cumulative distribution function (CDF) at a fixed time point post baseline. When the data are fully observed, the CDF can be estimated by the empirical CDF. When patients discontinue prematurely during the course of the study, the empirical CDF cannot be directly used. In this paper, we use multiple imputation as a way to estimate the CDF in longitudinal studies when data are missing at random. The validity of the method is assessed on the basis of the bias and the Kolmogorov–Smirnov distance. The results suggest that multiple imputation yields less bias and less variability than the often used last observation carried forward method. Copyright © 2013 John Wiley & Sons, Ltd.
