Parental affect profiles predict child emotion regulation and classroom adjustment in families experiencing homelessness

Parenting shapes the development of emotion regulation skills in early childhood, laying a key foundation for social-emotional adjustment. Unfortunately, high adversity exposure may disrupt parental emotion socialization practices and children's regulatory development. The current study used variable- and person-centered approaches to evaluate links among parental emotion expressiveness, children's observed emotion regulation, and teacher-reported adjustment among 214 4- to 6-year-old children experiencing homelessness, an indicator of high cumulative risk and acute adversity. Structured parent-child interaction tasks were recorded on site in emergency shelters over the summer and micro-socially coded for parent and child expressions of anger, positive affect, and internalizing distress. We anticipated that parental modeling of predominantly negative emotion expression would be associated with more child dysregulation during parent-child interaction and worse adjustment at school, as reported by teachers the following school year. Preliminary analyses indicated that children's observed difficulty downregulating anger was associated robustly with teacher-reported social-behavioral problems. Latent profile analysis was used to identify three patterns of parental emotion expression characterized by above-average expression of positive affect, internalizing distress, and anger. Parents’ likelihood of membership in the elevated anger profile significantly predicted children's observed difficulty down-regulating anger and higher social-behavioral problems at school. In addition to ongoing efforts to reduce poverty-related risk, supporting adaptive anger regulation in parents and young children may be important for enhancing resilience among families experiencing homelessness and similar conditions of high cumulative risk.     

Latent Tuberculosis Infection Screening Acceptability among Migrant Farmworkers

Latent tuberculosis (TB) infection is routinely diagnosed using the tuberculin skin test (TST). New methods of detection more specific than TST such as QuantiFERON TB Gold In‐Tube (QFT‐GIT) have been developed but evidence remains limited on their acceptability among migrant farmworkers. This article examined the acceptability of screening tests among migrant farmworkers working on the Arizona‐Mexico border. We conducted a cross‐sectional survey of migrant farmworkers via questionnaire. Of 83 participants interviewed, 53 (63.9%) believed that TB was a serious disease that could result in death and 59 (71.1%) considered TB a health concern in their community. Sixty‐four participants (77.1%) rated QFT‐GIT test as performing better than TST. Our study demonstrates preference for QFT‐GIT results over TST, and highlights migrant farmworkers’ considering themselves at risk of TB and TB as a health concern. Policies that create easy access and culturally appropriate, affordable healthcare for this vulnerable population should be encouraged.     

Does Living in a Fatherless Household Compromise Educational Success? A Comparative Study of Cognitive and Non-cognitive Skills

This study addresses the relationship between various family forms and the level of cognitive and non-cognitive skills among 15- to 16-year-old students. We measure cognitive skills using standardized scores in mathematics; non-cognitive abilities are captured by a composite measure of internal locus of control related to mathematics. A particular focus lies on father absence although we also examine the role played by co-residence with siblings and grandparents. We use cross-nationally comparable data on students participating in the Programme for International Student Assessment’s release for 2012. By mapping inequalities by family forms across 33 developed countries, this study provides robust cross-country comparable evidence on the relationship of household structure with both cognitive and non-cognitive skills. The study produces three key results: first, the absence of fathers from the household as well as co-residence with grandparents is associated with adverse outcomes for children in virtually all developed countries. Second, this is generally true in terms of both cognitive and non-cognitive skills, although the disadvantage connected to both family forms is notably stronger in the former than in the latter domain. Finally, there is marked cross-national diversity in the effects associated with the presence in the household of siblings and especially grandparents which furthermore differs across the two outcomes considered.     

Supporting the development of empathy: The role of theory of mind and fantasy orientation

Theory of mind (ToM) and empathy are separate, but related components of social understanding. However, research has not clearly defined the distinctions between them. Similarly, related constructs, such as fantasy orientation (FO), are associated with better ToM understanding; however, little is known about how FO may provide a context in which both ToM and affective empathy develop. Children between the ages of 3 and 5 (N = 82) completed a battery of ToM, empathy, and FO measures. Results demonstrated a developmental progression from ToM to affective empathy: 3‐year‐olds were likely to have neither, 4‐year‐olds were likely to have ToM only, and 5‐year‐olds were likely to have both. Additionally, results indicated that FO predicted affective empathy above and beyond ToM ability, suggesting that children whose play is high in fantasy are more practiced than their peers in sharing emotions. These findings are discussed in terms of how children's propensity toward fantasy play may contribute to their social development.     

What can television do? Cultural representations of border violence in FX’s The Bridge

FX’s The Bridge uses the two decades of violence against women in Juárez, Mexico, as a backdrop for a crime procedural drama about a serial killer. While there is a long history of cultural activism about the murders, The Bridge is the first mainstream television show to address the violence. I argue that while the show repeatedly centers police and journalists rather than community organizers, and thus limits the possibility of representing the social geography of the US–Mexico border, its moments of contradiction open up more complicated ways to understand the violence.     

Condom Failure: Examining the Objective and Cultural Meanings Expressed in Interviews With African American Adolescents

The purpose of this study was to explore the meaning and context of self-reported “condom failure” among sexually active African American adolescents. Semistructured interviews regarding methods of protection from pregnancy and sexually transmitted disease (STD) with 124 youth (ages 14–19 years) were content analyzed. The findings suggested three meanings of condom failure. First, condom failure represents a legitimate and important risk related to sexual activity. Second, it can serve as an excuse repertoire for adolescents who engaged in unprotected sex and later experienced either pregnancy or a STD. Third, it may serve as an explanation for males who deceive their partners into having unprotected sex. The findings are discussed with regard to their implications for HIV or STD prevention and research.     

Regimes of Mobility Across the Globe

Mobility studies emerged from a postmodern moment in which global ‘flows’ of capital, people and objects were increasingly noted and celebrated. Within this new scholarship, categories of migrancy are all seen through the same analytical lens. This article and Regimes of Mobility: Imaginaries and Relationalities of Power, the special issue of JEMS it introduces, build on, as well as critique, past and present studies of mobility. In so doing, this issue challenges conceptual orientations built on binaries of difference that have impeded analyses of the interrelationship between mobility and stasis. These include methodological nationalism, which counterpoises concepts of internal and international movement and native and foreigner, and consequently normalises stasis. Instead, the issue offers a regimes of mobility framework that addresses the relationships between mobility and immobility, localisation and transnational connection, experiences and imaginaries of migration, and rootedness and cosmopolitan openness. The introduction highlights how, within this framework and its emphasis on social fields of differential power, the contributors to this collection ethnographically explore the disparities, inequalities, racialised representations and national mythscapes that facilitate and legitimate differential mobility and fixity. Although the authors examine nation-state building processes, their analysis is not confined by national boundaries.
