Life Extension: Rolling the Technological Dice

The idea of radically extending average human life expectancy is an ancient one, but for most of human history exceedingly utopian. There is now, however, a revival of that idea, with some scientists and others arguing that it is possible and desirable. But the main problem with most of the life extension enthusiasm is that it is based almost entirely on the desire of some individuals to make it happen. The social consequences of success of such a venture are, however, either ignored altogether or dismissed on the grounds that any problems can be dealt with. In the end, none of our present human and social problems would be helped by radically longer lives and no obvious social benefits have been advanced to support it.

Acculturation, Enculturation, and Symptoms of Depression in Hispanic Youth: The Roles of Gender, Hispanic Cultural Values, and Family Functioning

The risk for depression increases as Hispanic youth acculturate to U.S. society. This association is stronger for Hispanic girls than boys. To better understand the influence of culture and family on depressive symptoms, we tested a process-oriented model of acculturation, cultural values, and family functioning. The data came from Project RED, which included 1,922 Hispanic students (53?% girls; 86?% were 14?years old; and 84?% were U.S. born) from Southern California. We used data from 9th to 11th grade to test the influence of acculturation-related experiences on depressive symptoms over time. Multi-group structural equation analysis suggested that both family conflict and cohesion were linked with depressive symptoms. Hispanic cultural values were associated with family cohesion and conflict but the strength and direction of these relationships varied across cultural values and gender. For girls and boys, familismo and respeto were associated with higher family cohesion and lower family conflict. Moreover, gender roles were linked with higher family cohesion in girls but not in boys. These results indicate that improving family functioning will be beneficial for boys' and girls' psychological well-being. This may be achieved by promoting familismo and respeto for boys and girls and by promoting traditional gender roles for girls.     

Young Adult Unemployment and Later Depression and Anxiety: Does Childhood Neighborhood Matter?

Young adulthood represents a developmental period with disproportionately heightened risk of losing a job. Young adult unemployment has been linked to increased mental health problems, at least in the short term. However, their possible long-term impacts, often referred as “scarring effects,” have been understudied, possibly underestimating the magnitude of mental health burden that young adult unemployment generates. This longitudinal study examined whether duration of unemployment during young adulthood is associated with later mental health disorders, after accounting for mental and behavioral health problems in childhood. Furthermore, the current study investigated whether childhood neighborhood characteristics affect this association and if so, in what specific functional ways. Data were drawn from a longitudinal study of developmental outcomes in a community sample in Seattle. Data collection began in 1985 when study participants were elementary students and involved yearly assessments in childhood and adolescence (ages 10–16) and then biennial or triennial assessments (ages 18–39; N?=?677 at age 39; 47% European American, 26% African American, 22% Asian American, and 5% Native American; 49% female). The current study findings suggest that duration of unemployment across young adulthood increased mental health problems at age 39, regardless of gender. Childhood neighborhood characteristics, particularly their positive aspect, exerted independent impacts on adult mental health problems beyond unemployment experiences across young adulthood. The current findings indicate a needed shift in service profiles for unemployed young adults—a comprehensive approach that not only facilitates reemployment but also addresses mental health needs to help them to cope with job loss. Further, the present study findings suggest that childhood neighborhoods, particularly positive features such as positive neighborhood involvement, may represent concrete and malleable prevention targets that can curb mental health problems early in life.

     

The Syrian conflict and public opinion among Syrians in Lebanon

Whom do ordinary Syrians support in their civil war? After decades of repression, the Syrian uprising unleashed an outpouring of political expression. Yet the study of Syrian public opinion is in its infancy. This article presents survey evidence from a large, diverse sample of Syrian refugees in neighbouring Lebanon, one of the first of its kind, and examines their support for the different factions fighting in the civil war. In so doing, it demonstrates that many conventional narratives of the conflict are oversimplifications of a more complex reality. The survey shows that the majority of Syrian refugees support one faction or another of the opposition, but a large minority sympathizes with the government. In line with existing accounts of the war, the government draws its popular support base from wealthier and less religious Syrians, as well as minorities. Nonetheless, large numbers of Sunni Arabs also side with the government, belying sectarian narratives of the war. The survey also finds that supporters of the opposition Islamists and non-Islamists are similar in many regards, including religiosity. The main distinction is that the non-Islamist support base is far more politically attentive than are Islamist sympathizers, in contrast to existing narratives of the war.     

On scale work: evidential practices and global health interventions

Abstract

Scalability can be understood as the ability to expand without changing. Yet, expanding an intervention to a global scale, we suggest, is a significant and difficult accomplishment. In this paper we propose to explore the kind of evidential exigencies that this accomplishment involves. To do so, we focus on the field of global health and examine how child immunization against the pneumococcus bacterium has been scaled up in low-income countries. The paper first attends to initial epidemiological scrutiny that revealed the existence of a large-scale public health problem and the possibility of an expandable solution (vaccination). It then describes the set-up of a funding arrangement using overseas aid to purchase vaccine doses manufactured by pharmaceutical companies, before paying attention to various frictions that affect the widespread use of pneumococcal vaccines. In these different moments through which scalability is accomplished, always partially and temporarily, we show that a dual activity can be witnessed, a pivoting between referential work and forward projection. To conclude, we suggest that scalability is more usefully approached as a form of expansion that is always attentive to the possibilities of change.
