We offer fresh evidence on the effect of migrant networks on two essential aspects of migration: (1) the total scale of migration and (2) the skill composition of migration. Our analysis is for the remarkable case of Spain, which experienced a full‐blown immigration boom from the mid‐1990s up to the Global Financial Crisis. To accommodate flexible substitution patterns across alternative migrant destinations, we use a three‐level nested multinomial logit model. We find a strong positive network effect on the scale of migration and a strong negative effect on the ratio of high‐skilled to low‐skilled migrants. Simplifying restrictions on the structure of cross‐destination substitutability are rejected by the data. (JEL F22, J61) 相似文献

Reconstructing contact situations for an unwritten language is a challenging task, as the sociolinguistic past of such speech communities is very rarely documented. The paper describes research in which a method of retrospective family interviews is applied, where respondents’ recollections about recent multilingual past and, in particular, about the language repertoires of their elder relatives, are converted into quantitative data. It is a case study of three neighboring villages in the mountains of Daghestan, each of which has its own first language. It is shown that the multilingual pattern in the cluster is now shifting from the knowledge of neighbor languages towards Russian – an external lingua franca which is not native to any of the communicants. 相似文献

This note provides an update on the ongoing debate over the World Bank's Doing Business project with a particular focus on its “Employing Workers” index, which is intended to measure difficulty of hiring, rigidity of working hours and difficulty of firing. The authors review the findings of studies that have used this index or been influenced by it and of those that inspired its construction. They go on to examine criticisms of this instrument, highlighting both conceptual and empirical problems. Their paper concludes with suggestions for alternative approaches and future research. 相似文献

The authors used cross-lagged analyses to examine the across-time influences on and consequences of adolescents' pregnancy intentions, wantedness, and regret. One hundred pregnant Latina adolescents were studied during pregnancy and at 6 and 12 months postpartum. The results revealed 4 main findings: (a) similar to what has been found in adult women, adolescents' lower prenatal pregnancy intendedness and wantedness predicted initial difficulties in parenting; (b) frequent depression symptoms predicted subsequent lower pregnancy intendedness and wantedness; (c) adolescents' poor mental health and harsh parenting of their child predicted subsequent higher childbearing regret, and (d) high childbearing regret and parenting stress were reciprocally related across time. In addition, adolescents' wantedness of their pregnancy declined prenatally to postbirth, and strong pregnancy intendedness and wantedness were not concurrently related to adolescents' poor prenatal mental health. The findings reveal how adolescents' thoughts and feelings about their pregnancies are influenced by and predictive of their mental health and parenting experiences. 相似文献

Concerted cultivation is the active parental management of children's educations that, because it differs by race/ethnicity, nativity, and socioeconomic status, plays a role in early educational disparities. Analyses of the Early Childhood Longitudinal Study–Kindergarten Cohort (n = 10,913) revealed that foreign‐born Latina mothers were generally less likely to engage in school‐based activities, enroll children in extracurricular activities, or provide educational materials at home when children were at the start of elementary school than were U.S.‐born White, African American, and Latina mothers, in part because of their lower educational attainment. Within the foreign‐born Latina sample, the link between maternal education and the three concerted cultivation behaviors did not vary by whether the education was attained in the United States or Latin America. Higher maternal education appeared to matter somewhat more to parenting when children were girls and had higher achievement. 相似文献

In this study, we analyse whether there are differences in attitudes towards nonprofit organizations (NPOs) between the generational cohorts of Baby Boomers, Generation X, and Millennials. We do so by analysing survey data from Switzerland in two steps, a Bayesian estimation as well as a cluster analysis. The overall results suggest that there are, at best, only few and small intergenerational differences: the only consistent effect we find are the more negative attitudes of the Baby Boomer cohort towards professional associations and towards sports NPOs, but those differences could be due to life cycle rather than intergenerational effects. Overall, our results suggest that the Millennial generational cohort is at least as interested in and willing to engage with NPOs as previous generational cohorts. 相似文献

Background
Physical activity (PA) is generally beneficial for bone health, but the effect of high levels of PA over many years, in older women, is unknown.Methods
T-score from Dual-energy X-ray absorptiometry (DXA), and self-reported baseline characteristics were recorded for 24 female, cross-country-skiing-competitors, aged 68–76?years, from the Birkebeiner Ageing Study. Data from 647 women in the same age range from the Tromso-6 population study, with recorded DXA findings, were used for comparison.Results
The athletes reported a median(range) of 9(1–34) participations in the 54?km, yearly ski-race, indicating long-term PA. They also reported more moderate and high levels of PA than women in the general population (52% vs. 12 and 30% vs. 0%, respectively). The athletes had lower body mass index (BMI) than the controls (mean BMI 21.7 vs 26.9?kg/m2, p?<?0.001). As many as 22/24(92%) of the athletes and 477/647(74%) of the controls had a low bone mineral density (BMD) (T-score?<???1), p 0.048, Pearson chi square test. Odds ratio (OR) of low BMD was 3.9 in athletes vs. controls (p 0.048, logistic regression), but adjusting for BMI largely diminished the effect estimate, which was no longer statistically significant (aOR 1.81, p 0.432). The proportion of self-reported fractures was the same in the two groups.Conclusions
This pilot study suggests that long-term, high levels of PA are associated with low bone mineral density in older women, and the finding might be due to differences in BMI. Despite the lower bone mineral density the athletes did not report more fractures.219.
