This paper contributes to the discussion on the effects of the number of children on female employment in Europe. Most previous research has either (1) compared these effects across countries, assuming an exogeneity of family size; or (2) used methods that dealt with endogeneity of family size, but that focused on single countries. We combine these two approaches by taking a cross-country comparative perspective and applying quasi-experimental methods. We use instrumental variable models, with multiple births as instruments, and the harmonized data from the European Survey on Income and Living Conditions (EU-SILC). We examine the cross-country variation in the effects of family size on maternal employment across groups of European countries with different welfare state regimes. This step gives us an opportunity to investigate whether the revealed cross-country differences in the magnitude of the effect of the family size on maternal employment can be attributed to the diversity of European institutional arrangements, as well as the cultural and the structural conditions for combining work and family duties. 相似文献

Self-Rated Health (SRH) is becoming one of the most popular indicator of population health. Nevertheless, a limited understanding still remains about the elements to which individuals refer when evaluating their health and how those elements act and interact in the evaluation process. In this study we use a structural equation model with latent variables to identify direct and indirect influences of various health dimensions (chronic morbidity, functional abilities and emotional health) and socio-demographic covariates (age, gender and education) on poor SRH. The sample consists of 25,183 Italian elderly aged 65 years and over, interviewed in the 2005 National Health Interview Survey. The results have pointed out the higher direct effect of psychological and emotional health on SRH, while the higher total effect is caused by chronic morbidity, which influences SRH both directly and altering functional and emotional health. Growing older, being a woman and having a low education negatively impacts on SRH. However, this is almost completely the result of the indirect effect exerted by the covariates, while their direct effect is not significant (gender), negative (age) or very modest (education). 相似文献

Disordered gambling is best conceptualized as a continuum of severity. Previous research has demonstrated the utility of studying individuals at all points of this spectrum. The sequence of the development of gambling problems and change in gambling involvement along this continuum of severity is not well understood. The present study examined the interplay between cognitive distortions and gambling involvement in a population sample recruited in Alberta, Canada. Data from 1372 participants over 4 assessment waves (5 years) were used to generate a 2-factor latent structure using gambling fallacies and gambling involvement measurements. Structural equation modelling showed that cognitive distortions more strongly predicted future gambling involvement than the reverse relationship, using the comparative fit index (CFI) and the root mean square error of approximation (RMSEA) to assess the models. In addition, cognitive distortions declined over time, whereas gambling involvement remained stable. The results of the study suggest that focusing primarily on cognitive mechanisms in public health initiatives for gambling disorders may be a more effective strategy than focusing on behavioural solutions. 相似文献

Since Robert Park’s foundational work on the ethnic press, the assimilation-pluralism paradigm has dominated research. This article proposes a new framework that combines ethnic media and diasporic media literatures to advance future scholarship. Ethnic media research can provide direction in better conceptualizing media of ethnic groups/diasporas and can reinforce the importance of racial context, and diasporic media research can address the limitations of the assimilation-pluralism framework and its inability to incorporate globalization, transnationalism, and hybridity. This article submits that ethnic media be conceptualized as specific to media produced by a diasporic or indigenous ethnic population within the host society and that future textual research on ethnic media engage a diasporic identity framework. The framework would (a) call attention to transnationalism; (b) call attention to local/transnational, ethnic/race, and inter-generational tensions; (c) focus on race as a salient and important local context for diasporic meaning; and (d) consider the site of production. 相似文献

Using multi-level modeling in 26 communities, this study examines contributors to three domains of community satisfaction—overall satisfaction, social life satisfaction, and infrastructure satisfaction. Human capital/demographic and social capital/network contributors emerge at both the individual and community levels in accounting for variation in community satisfaction. Some effects remain the same across levels and domains, but some effects differ. For example, living near family members increases satisfaction in all domains at the individual level, but at the community level, it decreases satisfaction in all domains. Residing in communities high in urbanicity reduces overall satisfaction, but has no effect on infrastructure satisfaction. Moreover, both individual and community level factors matter and impact community satisfaction. 相似文献

We investigate the relationship between homeownership and personal sense of mastery in the transition to adulthood and examine whether three important adult transitions (employment, marriage/cohabitation, and parenthood) moderate the impact of homeownership on mastery. Utilizing the National Longitudinal Survey of Youth—Young Adult Sample (N = 1,609), we estimate change models to assess the direct effects of homeownership on mastery as well as whether this impact is modified by the transition to adult roles. Homeownership increases the sense of mastery among young adults. Homeowners who are unemployed paradoxically receive a boost to mastery not experienced by those who are employed, and homeowners who are parents experience increased mastery, compared to those who do not have children. Owning a home has a positive influence on young adults' sense of mastery during a period when their mastery is in flux and they are accumulating new roles. 相似文献

For a continuous random variable X with support equal to (a, b), with c.d.f. F, and g: Ω1 → Ω2 a continuous, strictly increasing function, such that Ω1∩Ω2?(a, b), but otherwise arbitrary, we establish that the random variables F(X) ? F(g(X)) and F(g? 1(X)) ? F(X) have the same distribution. Further developments, accompanied by illustrations and observations, address as well the equidistribution identity U ? ψ(U) = dψ? 1(U) ? U for U ~ U(0, 1), where ψ is a continuous, strictly increasing and onto function, but otherwise arbitrary. Finally, we expand on applications with connections to variance reduction techniques, the discrepancy between distributions, and a risk identity in predictive density estimation. 相似文献

Rape on the college campus has gained increasing amounts of attention in higher education, mainstream news, and public policy. The prevalence rates of rape are especially high among students who frequent campus parties, such as those hosted by fraternities. Researchers have described this increased risk by focusing on individual attitudes and behaviors of fraternity members or on the organizational norms and practices within the fraternity party subculture. To incorporate these studies into a single theoretical framework, this essay uses a social psychological approach to connect individual‐level attitudes, (sub)culture, and behavior. I describe and apply identity theory and affect control theory, two structural symbolic interactionist theories, to explain why certain men are drawn to high‐risk fraternities and how membership reinforces hostility toward and abuse of women. In doing so, I suggest several avenues for future research that would increase social psychological understanding of the heightened prevalence of sexual victimization within the fraternity party subculture. 相似文献

Availability of free public education induces a transfer in kind among households with school age children. We provide evidence of the redistributive character of public education provision. We estimate structural quantile treatment effects of household income on the distribution of expected educational transfers in kind. Under the assumption that education quality is a normal good, better services (ancillary to the core education mission) supplied by private schools increase quality therein and reduce the incentives for wealthy households to enroll in public education. Because of these incentives, rich families benefit less from educational transfers in kind and the public education system is redistributive. Using household survey data from Italy, we find that an increase in net income reduces the value of the expected educational in kind transfers for compulsory education. 相似文献
