In 2008, the Government of Ecuador initiated a programme for productive return dubbed the Cucayo Fund, aimed at financing small businesses for migrants who were returning to the country. This programme has been a cornerstone in the new governmental policy on migration. In 2015, the IOM considered it an exemplary practice among the instruments enabling the economic and social reinsertion of returning migrants. In this article, based on the mining and analysis of the implementation data from the Cucayo Fund in the three provinces comprising Administrative Region No 7, we specifically examine the incidence of human capital accumulated by the migrants in the success of their ventures. Our results show that the experience and knowledge attained by the migrants abroad, and transfer of these to new activities, play a key and relevant role in the financed ventures and that, therefore, human capital must be incorporated with greater emphasis into debates on return.  相似文献

This commentary addresses the critique by Larzelere, Gunnoe, Roberts, and Ferguson (2017 Larzelere, R. E., Gunnoe, M. L., Roberts, M. W., &; Ferguson, C. J. (2017). Children and parents deserve better parental discipline research: Critiquing the evidence for exclusively “positive” parenting. Marriage &; Family Review, 53, 2435. doi:10.1080/01494929.2016.1145613[Taylor &; Francis Online], [Web of Science ®] [Google Scholar]: Marriage &; Family Review, 53, 24–35) ostensibly concerning the quality of research on “positive parenting” but actually critiquing physical punishment research. The critique revealed that the authors have a poor understanding of positive parenting. After explicating the different meanings of that term and describing what positive parenting is, we then address each of their four critiques of the physical punishment research. Each critique was flawed in multiple ways. After identifying their errors and correcting misinformation, we then raise broader issues about children’s right not to be hit and how professional organizations are increasingly recognizing the need and calling for an end to all physical punishment of children.  相似文献

This paper considers likelihood-based estimation under the Cox proportional hazards model in the situations where some covariate entries are missing not at random. Assuming the conditional distribution of the missing entries is known, we demonstrate the existence of the semiparametric maximum likelihood estimator of the model parameters, establish the consistency and weak convergence. By simulation, we examine the finite-sample performance of the estimation procedure, and compare the SPMLE with the one resulted from using an estimated conditional distribution of the missing entries. We analyze the data from a tuberculosis (TB) study applying the proposed approach for illustration.  相似文献

This study focuses on the long-term trend in happiness by income level in the United States. General Social Survey data suggest that in the past, rich and poor Americans were not only more equal in terms of income, but also in terms of their subjective wellbeing: the happiness gap between the poor and the rich has been increasing. Today’s poor suffer greater relative unhappiness than the poor of past decades. The gap between the poor and the rich is substantial, approximately 0.4 on a 1–3 happiness scale. The increase in the happiness gap is striking: comparing the 1970s to the 2000s, the gap has widened by about 40 % between the poor and the rich, and by about 50 % between the middle class and the rich.  相似文献

The authors build on prior research on the motherhood wage penalty to examine whether the career penalties faced by mothers change over the life course. They broaden the focus beyond wages to also consider labor force participation and occupational status and use data from the National Longitudinal Survey of Young Women to model the changing impact of motherhood as women age from their 20s to their 50s (n = 4,730). They found that motherhood is “costly” to women's careers, but the effects on all 3 labor force outcomes attenuate at older ages. Children reduce women's labor force participation, but this effect is strongest when women are younger and is eliminated by the 40s and 50s. Mothers also seem able to regain ground in terms of occupational status. The wage penalty for having children varies by parity, persisting across the life course only for women who have 3 or more children.  相似文献

This article explores the potential role of the Village model, a social initiative that emphasizes member involvement and service access, in helping communities to become more age-friendly. A survey of 86.3% of operational Villages examined activities designed to help members access a variety of supports and services consistent with the World Health Organization's (WHO) Global Network of Age-Friendly Cities and Communities program model, as well as other potential contributions to community age friendliness. Analysis revealed that 85.5% of Villages provided assistance with at least six of the eight WHO domains, but only 10.1% implemented features of all eight; more than one-third were engaged in direct or indirect efforts to improve community physical or social infrastructures or improve community attitudes toward older persons. These findings suggest that Villages and other social organizations may have untapped potential for enhancing their members’ ability to age in place consistent with the goals of age-friendly initiatives while also promoting constructive changes in the overall community.  相似文献

Two major shifts in contemporary work organizations—“employee participation” and “diversity management”—have typically been studied in isolation from one another. Building on theoretical work by Acker (2006a,b), we ask how the interaction of these two constructs has affected the pursuit of workplace democracy at two worker cooperatives in Northern California. Using qualitative methods, we find that distinct “diversity regimes” have emerged at these establishments, substantially affecting the configurations of inequality that evolved. We distinguish two types of diversity regimes—“utilitarian” and “communitarian”—which operate either to obscure the workings of inequality or to foster attention to their presence. Our results suggest that how sociodemographic differences are managed has material consequences for the development of egalitarian structures at work.  相似文献

This study investigates nominal contractual base-wage adjustments in Greece associated with the 2011 industrial relations reform which re-defined the limits within which base wages could oscillate and allowed workers’ associations to negotiate for wages at the firm level. The assessment covers the period 2010–2013 and is based on information extracted from the universe of firm-level contracts signed in this period. We found that firm-level contracts increased dramatically shortly after the reform, now covering a larger pool of workers, especially in larger firms, and are associated with higher base-wage reductions in the post-reform period. At the firm level, wage reductions are higher when workers are represented by a workers’ association rather than a typical trade union. In addition, a heterogeneous effect is uncovered regarding the factors that shape base-wage adjustments (firm size, profitability, structure of bargaining body and aggregate unemployment) between new and traditional forms of workers’ representation in collective bargaining.  相似文献

Instant ticket purchase gambling (ITPG) is pervasive in Ontario and has features that mimic slot machine play. Previous researchers have reported that ITPG is one preferred activity for at-risk/problem gamblers. In the general Canadian population, rate of participation in ITPG is second only to lottery ticket gambling. Both are particularly favored by youth and seniors. The next cohort of seniors will be Canada’s baby boomers, one-third of whom live in Ontario. Secondary analysis of Statistics Canada data revealed that adults in this cohort who buy instant gambling tickets (N = 1781) are significantly different from the complete group of their age peers (N = 4266) in number of activities pursued and frequency of involvement. At-risk/problem gambling prevalence was 10.2% amongst Ontario baby boomers who participate in instant ticket gambling, significantly higher than the 6.7% found amongst the total group of baby boom gamblers. For those who reported experiencing one or more of the Canadian Problem Gambling Index indicators for problem gambling (N = 237), 73% were buying instant tickets. Future research should consider cohort effects and explore combinations of preferred gambling activities that may increase risk for problem gambling. Social policy recommendations include the use of all ITPG venues as key locations for promoting awareness of problem gambling treatment services. This work was funded by Ontario Problem Gambling Research Centre.  相似文献
