文章基于2000—2016年重庆37个县(区)面板数据,使用序列DEA方法测算了重庆农业全要素生产率变动,在此基础上探讨了重庆农业全要素生产率增长的时间演变,并从理论和实证层面系统考察了城镇化和工业化对农业全要素生产率增长的影响。结果表明:首先,2000—2016年间重庆市农业全要素生产率呈上升趋势,2007年后重庆市农业全要素生产率增长更为明显,并且重庆市各地区呈现出明显的空间不平衡性。其次,动态面板模型的实证结果表明城镇化对农业全要素生产率增长具有显著正向影响,工业化对农业全要素生产率增长也具有显著正向影响。最后,研究还发现基础设施、教育水平以及金融发展程度对农业全要素生产率增长均具有显著正向影响,而产业结构对农业全要素生产率增长具有显著负向影响。  相似文献

In care-physical activity (care-PA) initiatives, primary care and sports are combined to stimulate PA among adults at risk of lifestyle related diseases. Preliminary results from Dutch care-PA initiatives for adults with a low socioeconomic status (SES) indicate a decrease in participants’ body weight and an improved quality of life, however, the elements that make these initiatives successful are yet to be identified. In total, 19 Dutch health promotion experts participated in our concept mapping (CM) of the effective elements of care-PA initiatives for adults with a low SES. The experts identified 111 effective elements of these initiatives, which were grouped into 11 clusters, focusing on: 1) approaching participants within the care-PA initiative, 2) barriers experienced throughout the initiative, 3) long-term implementation, 4) customizing the care-PA initiative to the target population, 5) social support, 6) structure and guidance, 7) the professionals within the care-PA initiative, 8) the accessibility of the care-PA initiative, 9) targeted behaviour and progression, 10) recruitment and administration, and 11) intersectoral collaboration. CM was useful for creating a valuable overview of these effective elements. Our results could be used to improve the development and implementation of future care-PA initiatives for adults with a low SES.  相似文献

国家角色模式的演变主要着眼于国家任务的承担及其实现方式的变化,近代以来,国家角色模式经历了从夜警国家到福利国家再到担保国家的三次嬗变。民营化及公私合作的发展促使国家与私主体越来越多地共同承担公共任务,分担了福利国家的给付之累,也促进福利国家模式向担保国家模式转变,其中,行政任务的民营化及公私合作是担保国家模式的主要背景,担保国家理论便是要探讨在民营化及公私合作背景下国家对公共任务的最终落实如何承担担保责任。担保国家与合作国家内涵相近但各有侧重,且均有重大意义。  相似文献

This study contributes to the growing body of literature on the outcomes of labour migration by focusing on the effects of migrant legal status on the economic and perceptual measures of migration success. To study the effects of legal status, we use a sample of Central Asian migrant women who work in Russia and of their native counterparts who occupy the same positions on the labour market. Similar to the studies in the developed settings, we find that a temporary legal status is associated with an earnings penalty and that permanent legal status corrects this earning disparity. We also find that both temporary and permanent migrant status is positively associated with perceptions of pay inequality but that, irrespective of these perceptions, both types of migrants are more likely to be satisfied with their jobs than natives. We interpret these findings within the legal and social context of migrant economic incorporation in Russia and relate them to the findings from other migrant-receiving settings.  相似文献

While socioeconomic barriers to learning have been well-documented by education, sociology, and social policy scholars, further research is needed to understand how students with low-socioeconomic status excel in high-performing schools. The collection and analysis of 20 in-depth interviews with female college students from different racial and socioeconomic backgrounds provide rich insights into the stark differences between the educational practices of low and high-SES students. Building on Bourdieu’s conceptualization of how habitus and capital influence practices in the field of education exposes unique, strategic practices that low-SES students use to attain educational success within a system of reproduction and power. While entering a high-performing school is often perceived as a definitive step for accessing high-quality educational resources, my findings illustrate how it is actually an important intermediary step within a more complex process. Increasing educational opportunity and attainment for low-SES students requires improving their access to social, cultural, and economic capital through knowledgeable mentors who contribute to a habitus and portfolio of capital which enable practices to successfully navigate and challenge the educational system.  相似文献

This paper discusses regression analysis of clustered current status data under semiparametric additive hazards models. In particular, we consider the situation when cluster sizes can be informative about correlated failure times from the same cluster. To address the problem, we present estimating equation-based estimation procedures and establish asymptotic properties of the resulting estimates. Finite sample performance of the proposed method is assessed through an extensive simulation study, which indicates the procedure works well. The method is applied to a motivating data set from a lung tumorigenicity study.  相似文献

While there is a global shift towards smaller families, some groups maintain relatively high fertility rates. The 2013 New Zealand census data were used to investigate the nature of fertility between ethnicities in New Zealand. The NZ Deprivation Index 2013 was used as a measure of socioeconomic status to determine the relationships with fertility. The results mirror research outside of New Zealand in that socioeconomic status is inversely correlated to fertility. Using crude average fertility rates, sole-ethnicity Pasifika and Māori ethnic groups still have substantially higher fertility than sole-ethnicity Europeans and Asians ethnic groups, even when simultaneously accounting for age, socioeconomic status, education, and religious affiliation. Christians have more children than individuals reportedly without any religion, and fertility rates drop on average for mothers who have higher formal qualifications. Our findings suggest that cultural, or other ethnic-specific factors differentially affect fertility for Māori, Pasifika, New Zealand European, and Asians as aggregated ethnic categories, respectively.  相似文献

Recent migration studies have adopted the lens of mobility to examine the stratifying effects of border policies, but few investigate the differential mobility of migrant families and children. This paper aims to contribute to the migration literature by considering the interplay between border policies, family configurations, and differential mobility. We apply the lens of differential mobility to the experiences of Chinese cross-border pupils – young child migrants with Hong Kong permanent residency who reside in Shenzhen, China, and cross the border to attend school. We begin by describing shifts in Hong Kong’s border and immigration policies since 1997, which have created a typology of families differentiated by mixed status, citizenship rights, and mobility. We then turn to four case studies of students with unequal border-crossing experiences to elucidate how border control constrains or promotes family mobility and perpetuates inequalities.  相似文献
