Informality,emotion and gendered career paths: The hidden toll of maternity leave on female academics and researchers

While the negative impact of child‐raising and caring on women's career progression in academia is well‐established, less is known about the role of academic women's lived experiences of maternity leave as an institutional practice. This article presents the findings of a qualitative study of the lived experiences of female academics and researchers in an Irish university. The analysis intrinsically links organizational structures and problems with the lived and felt dimensions of work. The findings point to the need for better structural accommodations for maternity leave which address the relationship between caring and career disadvantage within academia. The article adds to existing literature on the intersection of motherhood and academia by unpicking the specific role of maternity leave as both a lived experience and an institutional practice that can reinforce gender inequalities in academia.     

Bounded risk estimation of a linear combination of location parameters in negative exponential distributions via three-stage sampling

The paper deals with the problem of bounded risk point estimation for a linear combination of location parameters of two negative exponential distributions. Isogai and Futschik considered the situation when the location and scale parameters are all unknown. They proposed purely sequential procedures and gave second order expansions of the average sample sizes and risks. In this paper we propose three-stage procedures and derive second order expansions of the average sample sizes and risks. Further, we compare the results with those from previous work.     

基于结构方程模型的农民工可雇佣性的决定因素研究——基于中部六省的调查

农民工是中国人力资源的重要组成部分。从智能、技能、体能和心能四个维度构建农民工可雇佣性模型,根据调查问卷收集数据,运用结构方程验证了农民工可雇佣性模型的合理性,研究了农民工可雇佣性及其各维度间的关系。结果表明,各维度对农民工可雇佣性影响程度依次为:技能、心能、智能和体能。农民工因年龄、文化程度不同,在可雇佣能力、技能、心能和智能方面存在显著性差异,但是在体能上没有显著差异。     

国际视野下的社会主义改革脉络辨微

社会主义与市场经济的融合是社会主义改革的逻辑主线,"帕累托最优化"理论衍生的社会主义经济问题大讨论构成了社会主义改革的理论渊源。20世纪中期以南斯拉夫、匈牙利为代表的东欧社会主义国家的"分权市场社会主义"模式开创了实践视域中的社会主义改革。苏东社会主义改革的失败孕育了改革模式的分野,诞生了"市场主导"的西方市场社会主义思潮。国际社会主义改革的逻辑演进启示我们,必须坚持社会主义与市场经济融合的改革路径,完善国家干预经济的改革理论,坚持"结构型"改革的路径抉择,构建社会主义与市场经济"多维融合"的制度模式,提升中国特色社会主义的理论与实践内涵。

陕西省人口城市化Logistic模型及其应用——基于结构突变的理论分析

城市化是走向现代化的必经阶段,准确的城市化预测是进行经济、社会建设的基础。在结构突变理论的基础上,用Logistic模型对1978～2010年陕西城市化率进行分析。结论表明：1999年为陕西城市化率的结构突变点,说明城市化率的增长受到外部冲击的影响,分段以后的拟合优度明显提高。分别以阈值0.8和1进行分阶段构建的Logistic拟合精度明显提高,但阈值为1的精度更高,说明陕西城市化还在加速,预测表明到2030年陕西城市化率将达到70%左右。总体而言,从1984年到2030年为陕西省城市化的加速阶段。城市化加速阶段的住房问题、人口膨胀、环境恶化、交通拥挤、社会治安问题必须妥善解决。

雾霾感知风险与公众应对行为的实证分析

通过在雾霾严重时期收集的大规模问卷调查数据,建立了雾霾感知风险等因素与应对行为之间关系的结构方程模型.分析显示,对环境信息越敏感、雾霾感知风险越大、对雾霾知识了解越多、雾霾感知可控性越大的公众会采取更多的防护与应对措施,他们对相关防护产品的购买意愿也越强.特别是,感知风险在环境信息与应对行为以及环境满意度之间起着重要的中介变量作用,即当雾霾污染引起人们的感知风险时,会促使他们采取更多的应对行为,并且对环境满意度评价产生负面影响.另外,雾霾感知可控性在雾霾知识熟悉度与应对行为以及环境满意度之间起着部分中介变量的作用.     

State‐led industrial development,structural transformation and elite‐led plunder: Angola (2002–2013) as a developmental state

From 2002 to 2013, Angola engaged in large‐scale state‐led reconstruction and development alongside an elite‐led appropriation and seizure of national assets. Until the oil price shock, Angola had been succeeding in promoting rapid economic growth, and possibly even significant social development, alongside a massive grab of wealth and power by local elites. Today, though an economic crisis has taken hold, frequent predictions of the country's imminent collapse have yet to be fulfilled. This article reviews the state's development planning and expenditure with a focus on public investment and industrial development to determine to what extent Angola during this period might be considered a developmental or petro‐developmental state. It is argued that, while more significant than generally thought, petro‐developmental outcomes were and are limited by the autocratic and neopatrimonial tendencies of the Angolan elite. Nevertheless, limited success with structural transformation may have lasting effects. Following its long civil war, the conditions existed for Angola to follow a new path of state‐led development. Though it may now be more difficult, structural transformation and economic diversification remain the only path to economic and social development.     

Who “Fills in” for Siblings and How? A Multilevel Analysis of Personal Network Composition and Its Relationship to Sibling Size1

In the midst of widespread fertility decline, I examine the relationship between sibling number and support network composition using multilevel regression on data from 25 countries. A fundamental structural effect of having fewer siblings is that individuals have a smaller pool of available close‐kin alters with whom to construct support networks. Consequently, networks of people with fewer siblings should be composed of different sorts of relations. Results confirm that such compositional adjustment occurs in systematic ways. Compared to those with three or more siblings, adults with none to two siblings (as separate categories) are more likely to expect support from parents, extended kin, and close friends but not more likely to do so from spouses/partners and children. Single children are also more likely to include neighbors and have smaller‐sized and/or impersonal networks. These findings contradict the primacy of familial ties in social support networks. Moreover, adjustment of support networks towards nonsibling ties occurs in culturally expected ways. Those with fewer siblings are generally only more likely to turn to ties for the types of support typically associated with those relations—parents for instrumental and financial support and friends for emotional support. Single children, however, also violate institutionalized expectations of social support by turning to ties for a wider range of social support. The results suggest that continuing declines in fertility could bring about both reinforcement and rearticulation of the sociocultural framing of close personal relationships. Moreover, consistent with recent research, the results show that personal networks are influenced more by individual‐level than country‐level factors.
