Exporting Poor Health: The Irish in England

In the twentieth century, the Irish-born population in England has typically been in worse health than both the native population and the Irish population in Ireland, a reversal of the commonly observed healthy migrant effect. Recent birth cohorts living in England and born in Ireland, however, are healthier than the English population. The substantial Irish migrant health penalty arises principally for cohorts born between 1920 and 1960. In this article, we attempt to understand the processes that generated these changing migrant health patterns for Irish migrants to England. Our results suggest a strong role for economic selection in driving the dynamics of health differences between Irish-born migrants and white English populations.     

Transnationalism,Networks and Emigration from Post-War Ireland

Transnationalism is one of the widely-used concepts in the study of contemporary migrations. This article assesses the value of a transnational approach to the study of post-war Irish migration, when over a million people left Ireland, the vast majority travelling to Great Britain. The principal conclusion is that informal personal networks transcended the borders of the nation state and the Irish in Britain existed in a transnational social space which spanned the Irish Sea and included fellow-migrants, and family and friends living at home.     

Migration and mobility on the Amazon frontier

Migration patterns within tropical forest frontiers are highly complex and multidirectional, with movements to, from, and within these regions likely driven by different macro and micro factors. As such, several different conceptual models have been suggested to explain these dynamics. This paper uses data from a panel survey of households in a frontier region of the western Brazilian Amazon along with “second hand” reports on where people have moved to evaluate these conceptual models. Our rich data set, collected over nearly a decade from hundreds of households, allows us to compare households who arrived at different ages to assess predictions of the life cycle hypothesis; those who have been in the state (or on their properties) for different numbers of years to investigate the turnover hypothesis; those who arrived with different levels of capital to examine path dependence as suggested by conceptual models that focus on wealth dynamics; and the destination and purpose for moves from and within the study region to look for evidence of the frontier expansion hypothesis. We do not find any evidence for the turnover hypothesis, perhaps due to the favorable biophysical and market conditions in our study region. However, patterns in this region are consistent with all of the other conceptual models, reflecting the overlapping theoretical foundations of the models, and the complexity of migration and mobility on the frontier.     

Compensation and Community Corrosion: Perceived Inequalities,Social Comparisons,and Competition Following the Deepwater Horizon Oil Spill

After disasters, victim compensation programs are typically associated with individual healing and community rebuilding. But postdisaster compensation systems also have the potential to introduce confusion and competition, further fraying the social fabric of communities affected by trauma. To assess the perceived effects of disaster compensation processes on community social relations, as well as the mechanisms that underlie such effects, we turn to the case of the Deepwater Horizon oil spill, after which BP implemented one of the largest compensation systems in U.S. history. Using data from interviews of residents of four Gulf Coast communities, we examine the extent to which this claims process hindered efforts to recover from this disaster. Our data suggest that while BP money helped some residents in the Gulf during a difficult economic time, many interviewees perceived uncertainty, randomness, and unevenness in the compensation process, which led to negative social comparisons and competition among community members. Because of this animosity, we argue that BP's compensation system was a disruptive mechanism that contributed to community corrosion and introduced another source of psychological stress into already‐traumatized areas.     

Promoting “Zest for Life”: A Systematic Literature Review of Resiliency Factors to Prevent Youth Suicide

Suicide is a leading cause of death among youth globally. In this critical interpretive synthesis, we examined literature on resiliency factors and suicidality. Systematic searches identified 474 articles, 37 of which were included. Results revealed internal (positive self‐appraisal, zest for life, personal traits, and coping skills) and external factors (social support system and inclusive environments) contribute to resilience among youth, with age, sex and gender, and Indigenous identity as important intersecting considerations. Findings validated fostering resilience as primary suicide prevention among youth, with little explanation for how these factors may work to protect youth from suicidality. Continued research in this area requires a focus on how to promote resilience at the community and systems levels.     

The impact of kin support on urban American Indian families

Scholars believe that family ties extending out to previous generations, called kin support, may have allowed American Indians to withstand traumatic events. Although a series of traumatic and historical events disrupted the social structures of family life, kin support was found to be a major factor in the survival of American Indians. This study utilized the Fragile Families and Child Wellbeing Study to compare American Indians and whites (n = 1227) in factors that impact kin support. While urban American Indian mothers were similar to whites in a number of elements, American Indian mothers that were not married, fell below the poverty threshold, were younger in age and co‐resided with kin were more likely than their white counterparts to receive kin support. Implications for urban American Indian mothers suggest that maintaining their role as kin keeper may serve as an intrinsic reward and motivation for caring for kin. The role of a kin keeper may also promote the unique contribution in their families and the preservation of their culture. Given the minimal research in this area, results of this study can be used to guide future research and the development of intervention strategies for practitioners working with American Indian families.     

Use of the Bootstrap and Cross-Validation in Ridge Regression

Several existing methods for the choice of the ridge parameter are reviewed, and a bootstrap method is proposed. The bootstrap provides independent measures of prediction errors based on multiple predictions along with an estimate of the standard error of prediction. The bootstrap and selected competitors are compared through Monte Carlo simulations for various degrees of design matrix collinearity and varying levels of signal-to-noise ratio. The procedure is also illustrated by application to two published data sets. In one case, the bootstrap choice of the ridge parameter leads to a smaller mean squared error of prediction than the ridge trace method. In the second case, an optimal choice of no perturbation is confirmed. Benefits of the bootstrap choice include its less subjective nature, ease of implementation, and robustness.
