Mobile communication and refugees: An analytical review of academic literature

Over the past decade, an expanding literature has explored the ways in which refugees rely on mobile communication technologies to stay in touch with a wider community and to access relevant information and services in their new places. Nevertheless, challenges linked to (a lack of) digital literacy and accessibility among refugees, and associated risks of technology use can negatively affect their empowerment and participation in a “mediatized” society. In light of the mutually shaping processes emerging between technology and society, this article provides an overview of studies focusing on the relationship between mobile communication practices and refugee lives under different circumstances. Using the concept of affordances as an analytic tool, this article looks into ways in which existing studies address the possibilities and vulnerabilities of mobile communications, the social conditions, and the agency of refugees in engaging with mobile technologies in the different temporal and spatial dimensions of their migration trajectories. Future studies should explore more collective processes and the power dynamics involved in the appropriation of mobile technologies by different migration actors.

Similarities and Dissimilarities in Spouses’ Narratives of Miscarriage: A Dyadic Analysis of Communicated Narrative Sense-Making and Well-Being

Drawing upon communicated narrative sense-making (CNSM) theory, we explored how husbands and wives narratively make sense of their miscarriage and links to well-being. Specifically, we analyzed how the narrative theme, sequence, and similarity related to spouses’ perceived stress and relational satisfaction. Heterosexual married couples (n = 185; N = 370) who had experienced a miscarriage responded to online questionnaires in which they told the story of their pregnancy loss and completed measures of well-being. Seven miscarriage story themes emerged – hope lost, factual, time heals, helpful support, unhelpful support, cautiously optimistic, and guilt/shame. Findings demonstrated that husbands’ themes accounted for differences in their relational satisfaction, whereas wives’ themes accounted for differences in their perceived stress. Analyses on narrative similarity revealed couples with different themes reported higher relational satisfaction than those with similar themes. Further, those couples with the same narrative sequences (i.e., contaminated, redemptive, or ambivalent) reported less perceived stress than those with different narrative sequences. These findings suggest that storying miscarriage helps both husbands and wives process loss in unique ways.     

Inference and Decision Making for 21st-Century Drug Development and Approval

ABSTRACT

The cost and time of pharmaceutical drug development continue to grow at rates that many say are unsustainable. These trends have enormous impact on what treatments get to patients, when they get them and how they are used. The statistical framework for supporting decisions in regulated clinical development of new medicines has followed a traditional path of frequentist methodology. Trials using hypothesis tests of “no treatment effect” are done routinely, and the p-value < 0.05 is often the determinant of what constitutes a “successful” trial. Many drugs fail in clinical development, adding to the cost of new medicines, and some evidence points blame at the deficiencies of the frequentist paradigm. An unknown number effective medicines may have been abandoned because trials were declared “unsuccessful” due to a p-value exceeding 0.05. Recently, the Bayesian paradigm has shown utility in the clinical drug development process for its probability-based inference. We argue for a Bayesian approach that employs data from other trials as a “prior” for Phase 3 trials so that synthesized evidence across trials can be utilized to compute probability statements that are valuable for understanding the magnitude of treatment effect. Such a Bayesian paradigm provides a promising framework for improving statistical inference and regulatory decision making.     

Frustration in Infancy: Implications for Emotion Regulation,Physiological Processes,and Temperament

A study sample of 162 six‐month‐old children was selected from a larger sample of 346 infants on the basis of parents' report of their infants' temperament and a laboratory assessment of temperament. Infants were classified as easily frustrated and less easily frustrated and compared on a number of emotion regulation, physiology, and temperament measures. Results indicated that male and female infants were equally likely to be classified as frustrated and less easily frustrated; however, male infants were less able to regulate physiologically. Easily frustrated infants used different emotion regulation strategies and were observed to be less attentive and more active than less easily frustrated infants when observed in the laboratory. These infants were also characterized by their parents as more active, less attentive, and more distressed to novelty. Infants classified as easily frustrated were more reactive physiologically and less able to regulate physiological reactivity than their less easily frustrated counterparts. It is hypothesized that this cluster of characteristics may constitute a unique temperamental type that may have implications for other types of behavioral functioning. Limitations of the study are that observations are based on a single brief assessment of the infant, modest effect sizes were found, and the study is cross‐sectional.     

Testing the Effects of Collectively Expected Durations of Migration: The Naturalization of Mexicans and Cubans

This study tests a hypothesis that Mexican foreign‐born immigrants who came to the United States for economic reasons naturalize less often than Cubans who immigrate for political reasons. It uses information from the Panel Study of Income Dynamics, Latino Sample, a national sample of 7,453 respondents from the 1989 Latino National Political Survey (LNPS) and the 1990 Panel Study of Income Dynamics (PSID). Ordinal logistic regression is used to examine the hypothesis. The results indicate that while more Mexicans plan to apply or have applied for naturalization, proportionately more Cubans than Mexicans have naturalized. Cuban political immigrants who came to the United States during the first half of the 1960s naturalize more often than their Mexican counterparts. However, the effect of ethnic identity on naturalization is mediated by a number of other predictors of naturalization such as gender, race, urban residence, socioeconomic status and acculturation.
