Objectives To examine the prevalence of gambling and types of gambling activities in a sample of undocumented Mexican immigrants. Design Non-probability cross-sectional design. Setting New York City. Sample The 431 respondents ranged in age from 18 to 80 (mean age 32), 69.7% were male. Results More than half (53.8%) reported gambling in their lifetime and of those most (43.9%) played scratch and win tickets or the
lottery. In multivariate analyses men reported gambling more than women [2.13, 95% CI = (1.03, 4.38)]. The odds of gambling
in their lifetime were higher among those reporting sending money to family or friends in the home country [2.65, 95% CI = 1.10,
6.38)], and those who reported 1–5 days as compared to no days of poor mental health in the past 30 days [2.44, 95% CI = 1.22,
4.89)]. Conversely, those who reported entering the U.S. to live after 1996 were less likely to report gambling [0.44, 95%
CI = (0.22, 0.89)] as compared to those who had lived in the U.S. longer. Conclusion There is a need to further explore both the prevalence and the severity of gambling amongst the growing population of undocumented
Mexican immigrants in the U.S. 相似文献

Forest burning stands as a highly used practice in the Brazilian Amazon Forest. Burning trees is the cheapest way to expand agricultural frontiers in the Amazon region. Nevertheless, the smoke generated in this process can produce undesirable negative effects, in particular health-induced problems by the polluted air. This study aims to investigate whether these effects on the health of the region’s population are statistically significant, using as variables mortality and morbidity rates associated with respiratory diseases. The estimated morbidity model was used to estimate the health damage to those people who became ill only by the fire.

Transition to adulthood is an accelerated and early process for care leavers that requires intensive preparation, training and support from child welfare services. This study aimed to explore the perceived readiness for independent living of a group of care-experienced young people preparing for leaving care in Spain and to compare it with the perceptions of their peers from the general population. A sample of 508 youth (50% women) aged 14–21 (M = 16.67; SD = 1.72) took part, of whom 279 were care experienced and 229 belonged to the general population in Spain. Participants' independent living skills, personal autonomy, self-efficacy and sociodemographic characteristics were assessed through an online survey using standardized instruments. Care-experienced young people displayed higher levels of life skills and autonomy in self-care, daily living at home and employment domains, but not related to making daily arrangements in their community. However, their educational level and self-efficacy levels were lower than in the comparison group. Work experience stood out as a significant predictor of care-experienced young people's life skills level. These findings support the importance of assessing life skills as an outcome of leaving care preparation services and providing care-experienced young people with real-life experiences to develop their life skills. 相似文献

In this paper, we present different “frailty” models to analyze longitudinal data in the presence of covariates. These models incorporate the extra-Poisson variability and the possible correlation among the repeated counting data for each individual. Assuming a CD4 counting data set in HIV-infected patients, we develop a hierarchical Bayesian analysis considering the different proposed models and using Markov Chain Monte Carlo methods. We also discuss some Bayesian discrimination aspects for the choice of the best model. 相似文献

Many organizations operate multiple business models (BMs) concurrently. Yet, we know little about the challenges of managing a BM portfolio in one organization. In this study, we examine complexity as an important issue facing multi-BM firms. We differentiate complexity within a single BM from the complexity of links between BMs managed by a focal organization. Linking the BM and corporate strategy literatures, we discuss important dimensions and consequences of complexity in a BM portfolio. The sharing of similar activities and partners and the redeployment of activities and partners across BMs are important dimensions of the complexity of an integrated BM portfolio. We also suggest that BM portfolio complexity should be aligned with organizational design in terms of the centralization or decentralization of the decision-making process, and identify the positive effect of BM portfolio complexity on building imitation barriers. 相似文献

The increasing national diversity of coworkers has no consensus on its impact on performance. Using a team's predominant nationality as a proxy for national diversity and national identity, there is robust evidence that it affects team and individual performance. Detailed worker-level data from a highly globalized industry, association football, show a nonlinear relationship between performance and the predominant nationality of a team's roster. As the number of members from the predominant nationality increases, performance declines. However, beyond a threshold level, performance rises. It follows that performance benefits from national diversity when the predominant nationality is small and from national identity when it is large. (JEL M14, Z21, Z22, J15) 相似文献

Despite the large number of families with at least one undocumented parent, little research has investigated mothering amid the threat of immigration enforcement. We present results of a community-based participatory study with 7 Latina mothers who describe their experiences of parenting while navigating the possibility of deportation. Undocumented mothers found meaning in caring for their children. Yet due to restrictions related to immigration status, mothers were unable to support their children as they intended and feared their deportations would leave children without care, contributing to psychological duress. We provide recommendations for practitioners working with mixed-status families. 相似文献

Entrepreneurship serves as an engine for the economy and has sparked a great deal of scholarly interest since the Enlightenment. Today, universities play an essential role in knowledge transfer as drivers that promote this phenomenon. The objective of this study is to compare different theoretical models that seek to explain the variables involved in entrepreneurial intention among university faculty using an automatic structural learning method of Bayesian networks. The sample was comprised of 1,068 professors from Spanish public universities between the ages of 24 and 77 (M = 43.54, SD = 9.78). The results show that the variables that directly predict entrepreneurial intention are self-efficacy, desirability, attitude and social norm. These results are interesting for further exploring knowledge of the variables involved in the process of entrepreneurship at the university level and proposing systems to foster entrepreneurship. 相似文献
