Rhetoric and Reality of Economic Self-sufficiency Among Rural,Low-Income Mothers: A Longitudinal Study 总被引:3,自引:3,他引:0
Leigh Ann Simmons Elizabeth M. Dolan Bonnie Braun 《Journal of Family and Economic Issues》2007,28(3):489-505
This study examined the contributions of maternal labor force participation and marital status on economic self-sufficiency
over time for rural mothers. Data were from 174 rural families participating in three waves of data collection in Rural Families Speak. χ
2 and multiple logistic regression were utilized. Results revealed only one-third of mothers moved toward economic self-sufficiency
over three years. Maternal education, employment status, and weekly work hours were associated with improved economic well-being.
Compared to single-parent families, unmarried-couple and married-couple families had increased odds of improving economically.
In an analysis of all mothers with partners, married or unmarried, martial status was not significant in economic improvement.
Findings suggest the role of marriage in welfare reform for rural families should be reconsidered.

Labor force participation and juvenile delinquency in Taiwan: a time series analysis 总被引:1,自引:1,他引:0
This study examines the null hypothesis of Granger no-causality between labor force participation (LFP) and juvenile delinquency
in Taiwan. In order to explore this issue more thoroughly, this study adopts the approach proposed by Toda and Yamamoto (1995,
Journal of Econometrics, 66(1–2), 225–250). It uses official time-series data provided by the Government of Taiwan. After estimating both a four- and
five-variable VAR system, one that substitutes both male and female LFP rates for the aggregate LFP rate, the primary findings
of this study reveal the following: The higher the past juvenile crime rate, the lower the future aggregate and female LFP
rate will be. In addition, the higher the past male LFP rate, the higher the future juvenile crime rate will be. These findings
are quite robust in terms of different lag-length structures.

Tair Karazi‐Presler 《Gender, Work and Organization》2020,27(4):615-631
This article explores a surprising and seemingly mundane organizational practice: passing notes during professional meetings. Based on 34 in‐depth interviews with women in a hyper‐masculine organization — the Israeli military — this study focuses on what I term gendered practices of public ambiguity. It demonstrates how these practices shed light on three interrelated paths to power at work: (i) practices of public intimacy between men; (ii) practices of women's degradation by men; and (iii) practices of recognition claims by women. The tension between the publicity inherent in the routine passing of notes and the ambiguity of their contents calls for a more nuanced theorization of gendered power practices, which transcends the accepted dichotomy of doing and undoing gender, reproducing or challenging the symbolic gender order. The findings show that gendered micro‐practices can become polysemic symbolic spaces in which women redirect the flow of power, if only temporarily and locally, and turn it into a multidirectional and multi‐agentic resource. The conceptual contribution of these findings is discussed in terms of the positioning of women in hyper‐masculine environments as pragmatic subjects who (re‐)construct mechanisms of power out of the restricted repertoire available to them. 相似文献

对小微企业网贷平台的运营模式进行深入分析,发现其运行机制包括需求的同质化解构、需求的模块化生产、需求的风险评估、个性化需求加总,在此基础上构建小微企业网贷风险定价模型。为验证模型的有效性,抽取国内典型互联网金融平台“人人贷”上近期发生的小微企业标的并进行风险定价,将定价结果与实际利率进行比较,发现该模型适用于“卖方市场”的小微企业网贷,能够提供差异化的贷款利率,从而向小微企业提供个性化的网贷产品。 相似文献

People with serious mental disorders (PSMDs) are overrepresented both in prison deaths and during fatal encounters with the police in the community (deaths after police contact, DAPC). To identify common factors present across cases of who died during contact with the criminal justice system in Queensland, publicly available coroners reports were analysed (N = 38). The findings of the study indicated psychosis and mood disorders were the most common diagnosis in incarcerated PSMD deaths, and suicide was the most common cause of death for incarcerated PSMDs. Within incarcerated settings, access to healthcare records, medication compliance, risk assessment and monitoring, and safe housing of at‐risk prisoners may be potential areas to explore with regard to prevention. Similarly, PSMD DAPCs were more likely to be experiencing mood or psychosis disorders than other forms of mental disorder, and suicide and police shootings were the most common causes of death. In PSMD DAPC, inadequate mental health access, treatment noncompliance and comorbid substance use were included as potential areas that could direct research efforts toward prevention. 相似文献

金融危机对我国劳动力就业的影响 总被引:4,自引:2,他引:2
现阶段,由美国次贷危机引发的金融危机席卷全球,在全球经济一体化背景下,我国自然无法置身事外。金融危机对我国的影响表现在方方面面,其中对劳动力就业的冲击是最重要的问题之一。在现阶段的就业问题中,大学生就业和农民工返乡成为最为重要的两个方面。要应对金融危机对我国劳动力就业的影响,缓解就业压力,需要中央、地方政府、企业和个人的密切配合,从多方面入手寻求解决问题的根本途径。 相似文献

农村人口流迁动因研究评说 总被引:1,自引:1,他引:0
关于乡—城人口流迁的动因,历来为国内外学者所重视,研究成果颇多。那么迄今为止,都有哪些关于人口流迁动因的理论和观点?这些理论和观点能否完全解释20世纪80年代中后期中国的农村人口流迁现象?这些众多的理论和观点可以概括为三种:第一,宏观社会结构影响说;第二,生存与发展困境说;第三,劳动力剩余说。这三派观点各自都在自己所限定的范围内从一般意义上较为可信地解释了农村人口流迁的原因,但是由于方法论上的整体主义与个体主义的矛盾等原因,这些观点又有其局限性,因此,我们在借鉴这些观点解释20世纪80年代中后期以来中国农民的流迁动因的时候,应持审慎的态度。 相似文献
