Women entered the paid workforce in unprecedented numbers during the 20th century. Yet recent years have been witness to a creeping reversal in women's labor force participation. Why did the revolution stall? In response to debates over a “natural” limit to women's employment, or a cultural backlash against the dual-breadwinner household, we consider an alternative explanation, namely whether immigration has slowed the growth in female labor force participation. Using CPS data from 1998 to 2018, we show that the increase in the share of immigrants and children of immigrants in the population has reduced overall female labor force participation. However, immigration accounts for relatively little of the retreat from the labor force. Instead, the compositional effect of population change is overshadowed by behavioral shifts that affect both natives and immigrants. Lower participation rates among native-born women accounts for most of the overall decline. Despite persistent differences, we also find substantial convergence in the labor force behavior of native-born and foreign-born women, which bodes well for the long-term economic incorporation of immigrants and their children. 相似文献

为了从外部性角度说明目前陕西省交通基础设施的建设和投资在地域上存在的问题,为陕西省交通基础设施建设方向提供理论帮助,基于陕西省2009~2017年间各市相关数据,在交通基础设施对经济增长效应研究的直接效应和溢出效应基础上,加入空间要素,构建生产函数和空间权重矩阵,通过自相关检验(莫兰指数)、LM检验和 Hausman检验,选取合适的空间面板计量模型对陕西省交通基础设施的经济溢出情况进行研究。研究认为,2009~2017年间陕西省交通基础设施对经济增长的溢出效应(显著)整体为负,但依然存在正溢出的局部地区,即以西安为首的经济聚集区(西安、宝鸡、咸阳)和榆林、延安联合的陕北经济聚集区,资源过于集中和两个高地之间缺乏互联互通是整体呈现负溢出的重要原因。在地域分配的量和质上应充分考虑交通基础设施的溢出效应,避免资源过度集中在西安,在两个经济高地之间打通一条经济要道,并重点扶持相对落后又有发展前景的城市可促使陕西经济发展由总体集聚向总体扩散转变。 相似文献

大数据背景下个人信息处理行为既引发数据安全风险等负外部性,也会带来分享经济价值实现等正外部性,"大数据悖论"现象揭示了双重外部性成因。基于"外部性内在化"原理赋予信息主体以个人信息权并赋予数据控制者以大数据财产权虽有助分别规制其双重外部性,但网络大数据背景下其双重外部性规制彼此交互影响而面临两难困境。法经济学关于"损害之相互性"理论证立了基于"风险导向理念"规制个人信息处理以破解其两难困境的经济逻辑。大数据产业发展有赖个人信息处理的"外部性外部化"而实现分享经济。法经济学关于"公地喜剧"理论证立了基于"外部性外部化"规制个人信息处理而满足大数据产业发展需要的经济逻辑。大数据背景下个人信息处理的规制有赖从"压制型法"到兼及"回应型法"的理念转换,从"外部性内在化"兼及"外部性外部化"的机制并举,从数据资源权利配置兼及数字技术权力干预的措施协同,实现大数据产业创新与个人信息安全的有机平衡。 相似文献

汉字作为一种书写形体,笔画组合的丰富多样和间架结构的灵活多变,而使其“字形”成为复杂的美学构成,“书写”成为“书法”,并完成从造字到造形的转变。书法是汉字书写艺术,书法艺术深藏于汉字独特的形体结构之中。三位一体的整体架构、二维方块结体、平衡对称等汉字在形体构造上的诗性特征,既是人们对文字形体的一种审美预期,也是书法学家在书法创作时努力追求的美感。 相似文献

威廉·坦普尔爵士园林思想的研究,一直是学术界研究的薄弱之处。实际上,坦普尔在《论伊壁鸠鲁的园林,或论园艺》中系统地探讨了园林的起源、伦理意义和审美形态等问题。他从病原学的角度出发,把园林作为治疗人们过剩欲望的理想之地。他虽然赞同伊壁鸠鲁主义的退隐思想,却从政治德性、顺从自然、自由选择3个方面阐述了园林的退隐伦理。在园林之美上,他认为美在于形式,但是这种形式既包括欧洲的规则式之美,也包括中国的不规则之美。坦普尔的园林理论对我国当下的疗养院园林、私家园林的建设等有一定的指导意义。 相似文献

AbstractObjective: To examine rural-urban differences in college students’ cardiovascular risk perceptions. Participants: College students in rural (n?=?61) and urban (n?=?57) Kentucky counties were recruited from November 2012 to May 2014. Methods: This was a secondary data analysis of a cross-sectional study examining rural-urban differences in cardiovascular risk factors. Students rated their risk for developing high blood pressure, diabetes, high cholesterol, heart disease, having a stroke, and gaining excess weight. Chi-square and logistic regression were used for data analysis. Results: Rural students had lower odds of perceived high risk for developing high blood pressure compared to urban students (odds ratio (OR): 0.32, 95% CI: 0.11–0.96) after adjusting for race, sex, and body mass index. This association was not observed after adjusting for healthcare access variables. No other significant differences were observed. Conclusions: Efforts to raise perceived risk for developing hypertension among rural college students may be warranted. 相似文献

As U.S. manufacturing and production industries have declined, the growth of the care sector has increasingly become an important source of jobs for workers without a college degree. Often requiring some form of postsecondary credentialing, many care occupations can provide better wages, job stability, and possible upward mobility for less educated workers. However, employment patterns in paid care work are both gendered and racialized: women and workers of color are overrepresented in care occupations with fewer entry barriers, benefits, and lower pay. Although these patterns are well documented, the mechanisms producing them are less well understood. Using event history analysis and the National Longitudinal Survey of Youth (NLSY79), this study evaluates the explanatory power of neoclassical economic, status attainment, and social closure theories of occupational segregation for black women’s and men’s greater hazard or “risk” of entering care occupations, relative to white workers. Net of individual and closure mechanisms, significant residual effects suggest labor market discrimination remains a primary explanation for the over-representation of black workers in less credentialed care jobs with fewer benefits. 相似文献

The roles of small congregations and their social impacts are well known, but few theoretical studies investigate megachurch congregations. These mammoth organizations have the potential for advancing social good, but minimal research specifically focuses on the activities of these congregations in economic development (ED). This study addresses this dearth of information by answering the following research questions: (a) In what ways are megachurches involved in ED activities? (b) Who benefits from these programs and how are the programs offered? and (c) What factors influence megachurches to offer ED activities? We frame our investigation using both demand‐ and supply‐side arguments from Frumkin's (2002) model of nonprofit and voluntary action. Online survey data and follow‐up interviews with 42 megachurch leaders in the Dallas/Fort Worth and greater Houston areas show that megachurches are implementing ED activities in alignment with demand‐side explanations, especially when advancing opportunities for the unemployed and underemployed. However, supply‐side arguments provide more explanatory power, indicating that volunteer engagement with ED activities plays a significant role in the provision of ED services through megachurches. Our study offers a better understanding of why megachurches carry out ED activities with considerable attention devoted to how megachurches partner with other congregations, nonprofits, and government entities to encourage economic growth and improve the economic well‐being of community members. 相似文献
