Temporal and spatial variation in age-specific net migration in the United States

As fertility differences in the United States diminish, population redistribution trends are increasingly dependent on migration. This research used newly developed county-level age-specific net migration estimates for the 1990s, supplemented with longitudinal age-specific migration data spanning the prior 40 years, to ascertain whether there are clear longitudinal trends in age-specific net migration and to determine if there is spatial clustering in the migration patterns. The analysis confirmed the continuation into the 1990s of distinct net migration "signature patterns" for most types of counties, although there was temporal variation in the overall volume of migration across the five decades. A spatial autocorrelation analysis revealed large, geographically contiguous regions of net in-migration (in particular, Florida and the Southwest) and geographically contiguous regions of net out-migration (the Great Plains, in particular) that persisted over time. Yet the patterns of spatial concentration and fragmentation over time in these migration data demonstrate the relevance of this "neighborhood" approach to understanding spatiotemporal change in migration.     

Fathers' Early Emotion Talk: Associations With Income,Ethnicity, and Family Factors

Contextual, mother‐, child‐, and father‐level variables were examined in association with fathers' emotion talk to infants during a shared picture book activity, in an ethnically diverse, low‐income sample (N = 549). Significant main effects included the rate of emotion talk from fathers' romantic partners (i.e., the infant's mother), infant attention and distress, and sensitive parenting. Significant interactions were also found. Higher income African American fathers referred to negative emotions more than non‐African American higher income fathers. In addition, African American fathers who demonstrated more negative and intrusive parenting referred to positive emotions more than non‐African American fathers who demonstrated negative and intrusive parenting. Our findings support family systems theory and, specifically, the interdependence of individuals' behaviors within the family unit. Interaction effects are discussed with respect to cultural variation in beliefs about parenting behaviors and the cultural experience of African Americans, including the Black cultural experience and the minority experience.     

The outsourcing of primary activities: theoretical analysis and propositions

There is a considerable literature comparing the virtues of markets and hierarchies as alternative governance structures for economic transactions. But governance decisions are not simple dichotomous choices, and there has been increasing recent interest in the ‘swollen middle’ of hybrid organisational forms that combine market and hierarchical elements. One such hybrid is outsourcing, which has become a topic of considerable contemporary interest both in business circles and within the academic literature. The main contribution of this paper has been to combine the insights of resource dependency theory, the resource-based view of the firm, and transaction cost economics to provide both an explanation for the outsourcing of primary activities and a set of testable propositions about firms’ propensities of outsource.     

Storytelling as a tool: A family-based intervention for newly resettled Syrian refugee children

The conflict in Syria has resulted in a humanitarian emergency and one of the largest refugee crises in history. The Canadian government has welcomed over 40,000 Syrian refugees. Stressors caused by instability, conflict, and the resettlement process put refugee children at high risk for mental health problems. Anxiety is a common problem experienced by refugee children. Thus, early intervention is crucial to promote their adequate adaptation and development. This study explores the impact and value of a culturally specific family-based storybook intervention for newly resettled Syrian refugee children. Six refugee families participated. Anxiety symptoms were measured before and after the intervention, and families shared their experiences, thoughts, and feedback regarding the intervention. The results showed a significant decrease in children's anxiety symptoms. Furthermore, qualitative analyses demonstrated that the intervention was culturally relevant to Syrian refugee families and that it was effective in promoting children's overall well-being, agency, and family connectedness.     

The experience of disabled and non-disabled students on professional practice placements in the United Kingdom

There are limited comparisons between the experience of disabled students in higher education and their non-disabled peers, particularly on practice placements. This article presents the results of such a comparison, across six professional disciplines in one UK university. The results revealed that both disabled and non-disabled students reported positive placement experiences and also similar difficulties. Such difficulties were exacerbated for some disabled students, however, including as a consequence of the attitudes of others to disability. Recommendations for practice are identified that aim to enhance the placement experience of all students and to remove barriers to access.     

The relationship between Mean Cost Rating (MCR) and Kendall's rank correlation coefficient tau

Mean Cost Rating (MRC) has been used extensively in criminology to measure the power of prediction instruments. This paper shows that MCR is closely related to Kendall's rank correlation coefficient tau and demonstrates, by means of this relationship, how the significance of MCR can be tested. An example of its calculation is given.     

Sample size calculations for clinical studies allowing for uncertainty about the variance

One of the most important steps in the design of a pharmaceutical clinical trial is the estimation of the sample size. For a superiority trial the sample size formula (to achieve a stated power) would be based on a given clinically meaningful difference and a value for the population variance. The formula is typically used as though this population variance is known whereas in reality it is unknown and is replaced by an estimate with its associated uncertainty. The variance estimate would be derived from an earlier similarly designed study (or an overall estimate from several previous studies) and its precision would depend on its degrees of freedom. This paper provides a solution for the calculation of sample sizes that allows for the imprecision in the estimate of the sample variance and shows how traditional formulae give sample sizes that are too small since they do not allow for this uncertainty with the deficiency being more acute with fewer degrees of freedom. It is recommended that the methodology described in this paper should be used when the sample variance has less than 200 degrees of freedom.     

The politics of cross-border engagement: Mexican emigrants and the Mexican state

Reacting to migrants’ many, ongoing involvements with their home communities, sending states have increasingly adopted policies designed to resolve the problems of citizens living abroad and to respond to expatriates’ search for engagement, doing so in ways that best meet home state leaders’ goals. This article seeks to understand the factors shaping this interaction between sending states and emigrants abroad by studying two contrasting aspects of the Mexican experience—expatriate voting, a relatively new development, and provision of the matrícula consular, a long-standing component of traditional consular services, though one that has recently been transformed. Focusing on the complex set of interactions linking migrants, sending states, and receiving states, the article identifies the key differences and similarities between these two policies. Both policies suffered from a capacity deficit inherent in sending state efforts to connect with nationals living in a territory that the home country cannot control; both also generated conflict over membership and rights. Nonetheless, Mexico’s efforts to resolve the immigrants’ identification problems in the receiving society proved useful to millions; by contrast, a tiny proportion of emigrants took advantage of the first opportunity to vote from abroad. These diverging experiences demonstrate that sending states can exercise influence when intervening on the receiving society side, where the embeddedness of the immigrant population provides a source of leverage. By contrast, the search to re-engage the emigrants back home encounters greater difficulties and yields poorer results, as the emigrants’ extra-territorial status impedes the effort to sustain the connection to the people and places left behind. In the end, the article shows that extension to the territory of another state yields far more constraints than those found on home soil as well as unpredictable reactions from receiving states and their peoples, not to speak of nationals who no longer perceive the migrants as full members of the society they left.
