Places affected or threatened by extreme environmental disturbances confront a number of significant issues, including whether their populations will stay the same or change through migration. Research on Hurricanes Katrina and Rita shows some displaced residents returned to their disaster-affected communities once the built environment was restored, new migrants settled in affected places as part of the rebuilding effort, and the regional migration system grew more urbanized and spatially concentrated during post-disaster years. Research also shows that not all disaster-affected places recovered their populations. Our study examines whether differential recovery is systematically patterned along the rural–urban gradient. Using U.S. Census Bureau estimates and IRS county-to-county migration data, we investigate whether the 2005 hurricane season differentially exacerbated or altered previous migration trends across a rural–urban gradient that incorporates proximity to metropolitan areas and disaster-related housing loss. We find a rural–urban differential in Gulf Coast recovery migration: The disaster boosted migration among non-metropolitan counties, yet these increases were smaller and short-lived compared to the patterns found for metropolitan counties, most especially high loss metropolitan counties. Our findings encourage theories of environmental migration to incorporate spatial differentiation and scenarios of environmental changes to account for differential impacts on settlement patterns across the rural–urban continuum. 相似文献

The purpose of this study is to highlight the application of sparse logistic regression models in dealing with prediction of tumour pathological subtypes based on lung cancer patients'' genomic information. We consider sparse logistic regression models to deal with the high dimensionality and correlation between genomic regions. In a hierarchical likelihood (HL) method, it is assumed that the random effects follow a normal distribution and its variance is assumed to follow a gamma distribution. This formulation considers ridge and lasso penalties as special cases. We extend the HL penalty to include a ridge penalty (called ‘HLnet’) in a similar principle of the elastic net penalty, which is constructed from lasso penalty. The results indicate that the HL penalty creates more sparse estimates than lasso penalty with comparable prediction performance, while HLnet and elastic net penalties have the best prediction performance in real data. We illustrate the methods in a lung cancer study. 相似文献

Over the twentieth and twenty-first centuries, veterans have been more likely to enter into race/ethnic intermarriages than non-veterans. Theories of race/ethnic intermarriage variously point to how minority race/ethnicity, race/ethnically diverse social settings, progressive racial attitudes, and high socioeconomic status increase individuals’ likelihood of intermarrying. Veterans’ unique racial and socioeconomic characteristics may contribute to their greater likelihood of intermarrying relative to non-veterans: larger percentages of veterans than non-veterans are members of racial and ethnic minority groups, while military service increases individual service members’ long-term economic and educational prospects. At the same time, veterans share in common their exposure to the unique military environment, which may increase their likelihood of intermarriage by diversifying their social circles, and subjecting their attitudes and behavior to group norms that are more explicitly egalitarian than those of society at large. The present study considers these two possible explanations for veterans’ greater likelihood of intermarriage. We use data on seven cohorts of men over six decades in the Current Population Survey, representing a total of 1,456,742 observations, to decompose the difference in likelihood of racial intermarriage between veterans and non-veterans among married men aged 18–65. We find that across cohorts and decades, veterans’ greater likelihood of intermarrying is not fully explained by their race/ethnic and socioeconomic composition. We argue that veterans’ greater likelihood of intermarrying may therefore be driven by their exposure to the military environment. 相似文献

Problem
Pacific Islanders are disproportionately burdened by poorer maternal health outcomes with higher rates of pre-term births, low birth weight babies, infant mortality, and inadequate or no prenatal care.Purpose
The purpose of this study was twofold: (1) to explore maternal health care providers’ perceptions and experiences of barriers in providing care to Marshallese women, and (2) providers perceived barriers of access to care among Marshallese women. This is the first paper to explore perceived barriers to maternal health care among a Marshallese community from maternal health care providers’ perspectives in the United States.Methods
A phenomenological, qualitative design, using a focus group and in-depth interviews with 20 maternal health care providers residing in northwest Arkansas was chosen.Findings
Several perceived barriers were noted, including transportation, lack of health insurance, communication and language, and socio-cultural barriers that described an incongruence between traditional and Western medical models of care. There was an overall discord between the collectivist cultural identity of Marshallese families and the individualistic maternal health care system that merits further research.Discussion
Solutions to these barriers, such as increased cultural competency training for maternal health care providers and the incorporation of community health workers are discussed. 相似文献46.

Increasing family diversity during the past half century has focused national attention on how children are faring in nontraditional family structures. Much of the limited evidence on children in same‐sex couple families suffers from several shortcomings, including a lack of representative data. We use the National Health Interview Survey (2004–2012) and the National Survey of Children's Health (2011–2012) to identify children in different‐sex married and cohabiting families, never and previously married single‐parent families, and same‐sex couple families. Considering important characteristics such as the child's race or ethnicity and adoption status, household socioeconomic standing, family stability, and parent health, we examine the relationship between family type and parent‐rated overall child health. The results suggest that poorer health among children in same‐sex couple as well as different‐sex cohabiting couple and single‐parent families appears to be largely the product of demographic and socioeconomic differences rather than exposure to nontraditional family forms. 相似文献

Practitioners interview children in a range of settings to assess their wellbeing and to make decisions about their care. These interviews often have a significant memory component. Interviewing children about their past experiences, however, is a challenging task. It requires practitioners to be sensitive to children’s developmental capacities and vulnerabilities, to understand how to facilitate effective retrieval and reporting of information, and to set aside the usual dynamics and expectations of how adults and children communicate. Managing these challenges requires constant evaluation, self-reflection, and professional development. Fortunately, several decades of research into children’s memory and narrative development has provided a robust platform on which to base practice. Here, we provide a framework for devising a general approach to memory interviews with children that is both evidence-based and practical. 相似文献

Drawing on the work of Emile Durkheim ([1912] 1995) and Rodney Stark (2001) as well as research on the anti-ascetic thesis and reference group theory, we formulate a series of hypotheses regarding the effects of church attendance and importance of religion on adolescents' moral beliefs about marijuana use, getting drunk, hitting, and property offenses. The results of our study suggest that moral beliefs are more consistently and strongly related to importance of religion than to church attendance. Furthermore, much of the effect of church attendance on moral beliefs is mediated by importance of religion. Finally, we find evidence that importance of religion moderates (interaction) the effect of church attendance on moral beliefs. When adolescents believe religion is important, frequent church attendance further strengthens their moral beliefs. On the other hand, when adolescents believe religion is not important, frequent church attendance may actually reduce moral beliefs. 相似文献

The purpose of this study that focused on African American high school girls was threefold. First, the relationship of sports participation and victimization was explored. Second, the impact of sports participation on self-esteem was assessed. Third, the role of self-esteem and its disaggregated components (social acceptance, competence, and self-confidence) as mediators of the relationship between sports participation and victimization was examined. In accordance with the sport protection hypothesis, it was hypothesized that sports participation would be related to enhanced self-esteem and reduce victimization. Results suggest that sports participation appears to have some relationship to lower rates of victimization. There was also support for our assertion that sports participation was related to enhanced self-esteem. Finally, overall self-esteem and, specifically, the individual component competence mediated the relationship between sports participation and victimization. 相似文献
