Unintended consequences in traffic-light food labeling: A call for mixed methods in public health research

Abstract

Nudge theory describes how indirect suggestions and positive reinforcement can influence decision-making. We used nudge theory to implement a traffic-light labeling and choice architecture (modifying product placement) intervention at Harvard University cafeterias, but found no significant change in sales. Survey and focus group data showed that some students thought the labeling may exacerbate eating disorders, however, there is extremely limited research on potential negative consequences of labeling. One way to describe these findings is through 20th century philosopher Michel Foucault’s concept of biopower. Biopower manipulates cultural norms and nudges individuals to engage in self-surveillance and self-discipline, de facto subjugating themselves to certain ways of being. Biopower may lead to the creation of an in-group and an out-group based on who can adopt the new behaviors, such as healthy eating. Those in the out-group may face additional unintended consequences, highlighting the need for mixed-methods research to better evaluate public health interventions.     

Dating and friendships in adolescence: Variation across same-sex and other-sex romantic partners

This research examined associations between dating and number of friends for rural adolescents with same-sex and other-sex dating partners using longitudinal sociometric data (N = 2826; 55% female, 87% White, mean age = 14 at baseline). In multilevel models assessing within-person change, boys gained female friends when they were in same-sex romantic relationships, compared to when they were single. In contrast, girls in same-sex relationships lost female friends and gained male friends. Adolescents in other-sex romantic relationships gained same-sex friends compared to when they were single. Results advance understanding of adolescent social and sexual development, suggesting that sexual minority adolescents find allies when dating but may struggle to maintain same-sex friendships.     

A model of religion and death

This paper provides a rationale for several empirical findings regarding religion. The main one is between religion and the fear of death. Some empirical evidence indicates moderately religious individuals fear death more than either atheists or extremely religious individuals. The model also explains the positive relationship often found between religious activity (e.g. church attendance) and age. It also provides an explanation of the positive relationship between education and religious activity despite a negative relationship between education and religious belief.     

Covert repertoires: Ecotage in the UK 1

Ecological sabotage (ecotage) has been a feature of the more radical parts of the environmental movement in the Western world for several decades. While it may be perceived as being the preserve of underground cells of 'eco-terrorists', in the UK those who carry out small-scale acts of sabotage are also often engaged in relatively conventional political activity; view sabotage as a complement to other action, not as an end in itself; and are committed to avoiding physical harm to people. Drawing on ethnographic data from research with British activists, this article seeks to define ecotage and to explain its place in the repertoires of the environmental direct action movement in the UK. It is argued that the self-limiting form of ecotage in the UK has its roots in cross-movement debates that have developed over several decades and that national traditions remain important in understanding the development of social movement repertoires.     

Exploring and Adapting a Conceptual Model of Sexual Positioning Practices and Sexual Risk Among HIV-Negative Black Men Who Have Sex With Men

Estimates show a 50% lifetime human immunodeficiency virus (HIV) risk among Black men who have sex with men (BMSM) in the United States(U.S.). Studying the dynamics of sexual positioning practices among BMSM could provide insights into the disparities observed among U.S. groups of men who have sex with men (MSM). This study explored sexual positioning dynamics among HIV-negative BMSM and how they aligned with a theoretical model of sexual positioning and HIV/sexually transmitted infection (STI) risk among MSM. In-depth qualitative interviews were conducted with 29 HIV-negative BMSM between ages 25 and 35 in Los Angeles. Comments related to sexual behaviors were reviewed for relevance regarding oral or anal sexual positioning practices. Data presented represent the range of themes related to decision making regarding sexual positioning. Personal preference, partner attraction, HIV avoidance, and feeling obligated to practice partner preferences influenced sexual positioning. Drug use also affected decision making and was sometimes preferred in order to practice receptive anal intercourse. These variables build on the conceptual model of sexual positioning practices and sexual risk, and add understanding to the relationship between preferences, practices, and risk management. Future research on risk among HIV-negative BMSM should quantify the relative impact of personal preferences, partner attraction, partner type, compromise, and substance use on sexual positioning practices and risk.     

Surplus Chinese Men: Demographic Determinants of the Sex Ratio at Marriageable Ages in China

We explore the demographic factors contributing to China's unbalanced sex ratio at marriagable ages. We develop a stable population model of the sex ratio at marriagable ages, and compare a series of population projections with alternative underlying assumptions about the key demographic inputs. The stable population model demonstrates that several demographic factors interact to influence the sex ratio at marriagable ages, including the sex ratio at birth, population growth, the age gap of marriage partners, and the sex ratio of survival from birth to marriageable age. The population projections further demonstrate that policies that seek to reduce the sex ratio at birth and the age gap at marriage and, to a lesser extent, increase fertility would be most effective at alleviating the problem. But no demographic changes are likely to occur quickly enough to balance the sex ratio at marriagable ages in the near future.     

Immigration,ethnicity, and the loss of white students from California public schools, 1990–2000

This article investigates whether and the extent to which “white flight” from Hispanic and Limited English Proficient (LEP) students has been occurring in California’s public schools and further, examines the level (school or district) on which “white flight” may operate. Using school-level administrative data from the California Department of Education from 1990 to 2000, we estimate exponential growth rate models of white enrollment with school-level fixed effects. The results shed light on the implications of immigration for school segregation in the United States. The analysis indicates that white enrollment declined in response to increases in the number of Spanish-speaking LEP and Hispanic students, and that “white flight” from LEP or Hispanic students occurred more at the district than the school level in the case of primary schools, and at the school level for secondary schools. In addition, schools with higher percentages of Spanish LEP students in the school than the district, and with higher percentages in the district relative to the county, experienced greater losses in white enrollments than other schools, thus suggesting that higher levels of segregation in the wider metropolitan area accelerate white flight.
