Pre-adolescents' Peer-relational Schemas and Social Goals across Relational Contexts

Current theorists stress the context-specificity of social behaviors and social cognitions. Although researchers have started to investigate the relationship as one context that might influence social cognitions, relatively little is known about the influence of relational context on the social goals endorsed by children and adolescents. The current study tested the hypothesis that pre-adolescents' goals would vary between individuals as well as across relational contexts, and examined factors that might explain such variation. Participants (N  =  102, 11–12 years) filled in questionnaires regarding their social goals and self- and peer-perceptions when around each same-sex classmate. Both goals and perceptions displayed significant variation between individuals, as well as between different relationship contexts. The goals pre-adolescents pursued in different relationships were partly explained by varying perceptions of self and of the relationship partner in each relational context, as well as by the affective nature of the relationship. After accounting for the relationship-specific variation, few associations were significant at the individual level. The results highlight the importance of studying contextual variance in social goals and social cognitions in general.     

Racial Differences Between African and White Americans in the Presentation of Borderline Personality Disorder

Borderline personality disorder (BPD) is commonly thought of as a disorder of White females. Despite evidence indicating similar prevalence rates across races and genders, no study has examined the experience of BPD among ethnic minorities and how this differs from Whites. The affective and behavioral symptoms of BPD were studied in 17 African Americans and 27 White Americans with the disorder. Results indicated that African Americans experience greater affective intensity and emotional dysregulation, fewer self-harming behaviors, and more thoughts of interpersonal aggression than Whites. Differences in affective symptoms were accounted for by group differences in substance use and receipt of inpatient services, whereas differences in behavioral symptomatology persisted after adjusting for potential confounders. These findings suggest that not only is BPD not a disorder exclusive to White females, but that the experience of the disorder may differ substantially across races. Implications for future research and directions for developing culturally relevant treatments are discussed.

Cumulative Risk for Early Sexual Initiation Among American Indian Youth: A Discrete‐Time Survival Analysis

Approximately 3 million teens are diagnosed with a sexually transmitted disease (STD) annually; STDs rates for American Indian young adults are among the highest of any racial/ethnic group. An important risk factor for STDs is early initiation of sex. In this study, we examined risk for early initiation with 474 American Indian youth ages 14–18, using 11 risk factors from three developmentally important microsystems (family, school, peers) along with several individual characteristics; a cumulative risk index was also calculated. Discrete‐time survival analyses showed that predictors of early initiation differed by gender. For young men, younger initiation of sex was predicted by lower grades, liking school less, having peers with less prosocial attitudes, a greater likelihood of having used alcohol or drugs at first sex, and having higher sensation‐seeking. For young women, earlier initiation was related to having mothers who had their first child at an early age and who had less formal education, to having parents who had divorced, dropping out of high school, using alcohol/drugs at first sex, and higher sensation‐seeking. Higher cumulative risk was associated with elevated risk of sexual initiation, although the degree of added risk varied with age for women. Cumulative risk deserves broader attention in understanding the early initiation of sexual intercourse.     

The Association of Couples’ Relationship Status and Quality With Breastfeeding Initiation

Using data from the Fragile Families and Child Wellbeing Survey (N= 3,567), we examine the links between relationship status, relationship quality, and race and ethnicity in breastfeeding initiation. We consider four relationship types: married, cohabiting, romantically involved but not cohabiting (termed visiting), and nonromantically involved mothers. We find that even after adjusting for a wide range of sociodemographic factors, married mothers were more likely to breastfeed than unmarried mothers and that racial and ethnic differences in breastfeeding do not result from differences in marriage rates. Among unwed mothers, paternal provision of money or other assistance during pregnancy decreases the likelihood of breastfeeding. We conclude that relationship status, above and beyond demographic characteristics, is an important correlate of breastfeeding.     

Understanding Vulnerability: From Categories to Experiences of Young Congolese People in Uganda

This article problematises the ‘vulnerables’ category that the United Nations High Commissioner for Refugees applies to groups of refugees. Drawing on 9 months’ qualitative research with young Congolese refugees in Uganda, it presents research subjects’ self‐identification and lived realities that do not correspond to the homogenous, fixed ‘vulnerables’ ideal. Moreover, it argues that the ‘vulnerables’ categorisation approach can provoke a number of counter‐productive effects, including a focus on symptoms rather than causes, inflated numbers of ‘vulnerables’ and undermining indigenous support structures. An alternative approach that interrogates and addresses the contextual and relational aspects of vulnerability is proposed.     

Planning with Preschoolers: City Mapping as a Planning Tool

The United Nations Convention on the Rights of the Child requires that children ‘have the right to be heard in matters affecting them’ (Article 12). Given that planning matters such as housing, transport, services and recreation provision affect children, it is necessary, therefore, for planners to engage with children. While planning has made considerable progress in working with older children, preschool children have been overlooked. Preschoolers are commonly seen as lacking the understanding necessary to comprehend the city scale. This paper presents a tile-based city-mapping method that demonstrates preschool children do understand city-scale features and relationships. Further, this method could be used in planning to advocate for and to engage with very young children in planning conversations.     

When Evolution Works Against the Future: Disgust's Contributions to the Acceptance of New Food Technologies

New food technologies have a high potential to transform the current resource‐consuming food system to a more efficient and sustainable one, but public acceptance of new food technologies is rather low. Such an avoidance might be maintained by a deeply preserved risk avoidance system called disgust. In an online survey, participants (N = 313) received information about a variety of new food technology applications (i.e., genetically modified meat/fish, edible nanotechnology coating film, nanotechnology food box, artificial meat/milk, and a synthetic food additive). Every new food technology application was rated according to the respondent's willingness to eat (WTE) it (i.e., acceptance), risk, benefit, and disgust perceptions. Furthermore, food disgust sensitivity was measured using the Food Disgust Scale. Overall, the WTE both gene‐technology applications and meat coated with an edible nanotechnology film were low and disgust responses toward all three applications were high. In full mediation models, food disgust sensitivity predicted the disgust response toward each new food technology application, which in turn influenced WTE them. Effects of disgust responses on the WTE a synthetic food additive were highest for and lowest for the edible nanotechnology coating film compared to the other technologies. Results indicate that direct disgust responses influence acceptance and risk and benefit perceptions of new food technologies. Beyond the discussion of this study, implications for future research and strategies to increase acceptance of new food technologies are discussed.     

A Novel Approach to Chemical Mixture Risk Assessment—Linking Data from Population‐Based Epidemiology and Experimental Animal Tests

Humans are continuously exposed to chemicals with suspected or proven endocrine disrupting chemicals (EDCs). Risk management of EDCs presents a major unmet challenge because the available data for adverse health effects are generated by examining one compound at a time, whereas real‐life exposures are to mixtures of chemicals. In this work, we integrate epidemiological and experimental evidence toward a whole mixture strategy for risk assessment. To illustrate, we conduct the following four steps in a case study: (1) identification of single EDCs (“bad actors”)—measured in prenatal blood/urine in the SELMA study—that are associated with a shorter anogenital distance (AGD) in baby boys; (2) definition and construction of a “typical” mixture consisting of the “bad actors” identified in Step 1; (3) experimentally testing this mixture in an in vivo animal model to estimate a dose–response relationship and determine a point of departure (i.e., reference dose [RfD]) associated with an adverse health outcome; and (4) use a statistical measure of “sufficient similarity” to compare the experimental RfD (from Step 3) to the exposure measured in the human population and generate a “similar mixture risk indicator” (SMRI). The objective of this exercise is to generate a proof of concept for the systematic integration of epidemiological and experimental evidence with mixture risk assessment strategies. Using a whole mixture approach, we could find a higher rate of pregnant women under risk (13%) when comparing with the data from more traditional models of additivity (3%), or a compound‐by‐compound strategy (1.6%).     

Impact of Economic Conditions and Crises on Mortality and its Predictability

To investigate how economic conditions and crises affect mortality and its predictability in industrialized countries, we review the related literature, and we forecast mortality developments in Spain, Hungary, and Russia—three countries which have recently undergone major transformation processes following the introduction of radical economic and political reforms. The results of our retrospective mortality forecasts from 1991 to 2009 suggest that our model can capture major changes in long-term mortality trends, and that the forecast errors it generates are usually smaller than those of other well-accepted models, like the Lee-Carter model and its coherent variant. This is because our approach is capable of modeling (1) dynamic shifts in survival improvements from younger to older ages over time, as well as (2) substantial changes in long-term trends by optionally complementing the extrapolated mortality trends in a country of interest with those of selected reference countries. However, the forecasting performance of our model is limited (like that of every model): e.g., if mortality becomes extremely volatile—as was the case in Russia after the dissolution of the Soviet Union—generating a precise forecast will depend more on luck than on methodology and expert judgment. In general, we conclude that, on their own, recent economic changes appear to have minor effects on life expectancy in industrialized countries, but that the effects of these changes are greater if they occur in conjunction with other major social and political changes.
