Eating Regulation Styles, Appearance Schemas, and Body Satisfaction Predict Changes in Body Fat for Emerging Adults

Obesity and high body fat percentages are a major public health issue. The percentage of obese and overweight Americans has increased over the past 30 years. On average, overweight individuals with higher percent body fat than normal weight individuals are at increased risk for numerous negative outcomes both physically and mentally. A prime time to investigate changes in body composition and associated psychological influences on decision making is during the emerging adulthood period. The first few years of college are a time when adolescents begin to regulate for themselves their own eating behaviors. Previous research shows that freshmen gain weight and increase in percent body fat during their first year of college. The current study addresses the limitations of previous research by investigating (1) individual growth in percent body fat over a longer period of time in college than previous available research and (2) important psychological and sex differences in this growth. This study measures percent body fat across the first 3 years of college at 8 time points for 542 undergraduates (351 females, 65 %; 191 males, 35 %). Longitudinal data analysis was conducted to identify changes in percent body fat, psychological predictors of those changes, and how changes differ for males and females. Our study found that significant increases exist in percent body fat during undergraduates' college years and that change differs for males and females. In addition, through the use of nested hierarchical models, eating regulation style (autonomous or controlled regulation), appearance schema (self-evaluative salience or motivational salience), and body satisfaction were identified as influential predictors of change in percent body fat. For example, young females, who do not feel in control of their physical appearance yet spend a great deal of time maintaining their appearance, have the highest initial body fat percentage and the steepest increase in percent body fat. Overall, males and females with high autonomous regulation and high motivational salience are likely to maintain (instead of increase) percent body fat over the college years. Knowing the influence of these predictors can be useful for promoting health and intervening with young adults in the college setting and other emerging adults who are not enrolled in postsecondary institutions.     

Understanding Adolescent and Family Influences on Intimate Partner Psychological Violence During Emerging Adulthood and Adulthood

The intergenerational transmission of violence directed toward intimate partners has been documented for the past three decades. Overall, the literature shows that violence in the family of origin leads to violence in the family of destination. However, this predominately cross–sectional or retrospective literature is limited by self–selection, endogeneity, and reporter biases as it has not been able to assess how individual and family behaviors simultaneously experienced during adolescence influence intimate partner violence throughout adulthood. The present study used data from the Iowa Youth and Families Project (IYFP; N = 392; 52 % Female), a multi–method, multi–trait prospective approach, to overcome this limitation. We focused on psychological intimate partner violence in both emerging adulthood (19–23 years) and adulthood (27–31 years), and include self and partner ratings of violence as well as observational data in a sample of rural non-Hispanic white families. Controlling for a host of individual risk factors as well as interparental psychological violence from adolescence (14–15 years), the results show that exposure to parent–to–child psychological violence during adolescence is a key predictor of intimate partner violence throughout adulthood. In addition, negative emotionality and the number of sexual partners in adolescence predicted intimate partner violence in both emerging adulthood and adulthood. Exposure to family stress was associated positively with intimate partner violence in adulthood but not in emerging adulthood, whereas academic difficulties were found to increase violence in emerging adulthood only. Unlike previous research, results did not support a direct effect of interparental psychological violence on psychological violence in the next generation. Gender differences were found only in emerging adulthood. Implications of these findings are discussed in light of the current literature and future directions.     

Achieving Effective Collaborations to Help Communities Age Well

Effective policy responses to the ageing of the population are a priority area for government and non‐government agencies across Australia, particularly at the community level. This article focuses on the policy goal of ageing well at the local level, and more specifically, the strong principle of collaboration that underpins this goal. Too little is known about how to achieve effective collaboration in the ageing field. This article aims to address this by developing an analytical framework from the broad literature on collaborative processes, and applying this framework to data collected from interviews with stakeholders in ageing across two local communities in Queensland. While participants recognise the importance and strength of working together and provide local examples of how this has been achieved effectively, they also acknowledge the associated challenges and complexity. This all spanned the six factors of the framework: the context of ageing; the characteristics and relationships between partners; the need for adequate procedures; as well as structure and relationships aimed at building capacity; a shared sense of purpose; and access to adequate resources.     

Size and e-Democracy: Online Participation in Norwegian Local Politics

This study of municipal e-participation in Norway, comprising local politicians as well as citizens, explores the impact of municipal size on online participation. First, the analyses show that the conventional predictors of offline participation also influence online participation, but the Internet encourages more activity among young people. Second, the same digital divides are generally found within the local political elite as among the citizens. Municipal size is, however, an exception. In the case of the local politicians, higher online participation rates are found in populous municipalities. This territorial digital divide is absent among the citizens. The findings indicate that the relatively high level of traditional participation in small municipalities also promote e-participation.     

Outline Shape Analysis on the Trochlear Constriction and Olecranon Fossa of the Humerus: Insights for Sex Estimation and a New Computational Tool,

Sex estimation through visual analysis of the distal humerus can contribute to establishing the biological profile of an unidentified skeletal individual. Using statistical shape modeling, the trochlear constriction open curves and olecranon fossa closed outlines of 151 humeri were digitized and analyzed. The shape configurations exhibited strikingly different degrees of sexual dimorphism when evaluated using linear discriminant analysis with leave‐one‐out cross‐validation. The trochlear constriction performed poorly, correctly classifying 63.6% of the individuals. However, the olecranon fossa showed high sexual dimorphism, presenting a 94.0% accuracy. A simpler model using only two principal components was also generated. While the accuracy is slightly inferior (88.1%), it has the advantage of being constrained to bidimensional components that were translated into morphoscopic variables within a simulator interface. This allowed us to implement the method through a web application that does not require users to be trained in landmark digitization or have knowledge of geometric morphometrics.     

The spectre of Haiti: structural antiblackness,the far-right backlash and the fear of a black majority in Brazil

Abstract

This article situates the far-right backlash in Brazil within the larger Latin American context, including its colonial legacy, leftist governments’ failure to deliver promises of inclusion, and the US–China geopolitical dispute over the region’s strategic natural resources. By situating Bolsonaro’s electoral victory within these dynamics, our analysis presents an alternative to two common perspectives. First, studies of the region’s political moment and of Brazilian society in particular do not pay enough attention to institutional and everyday racism, and instead focus mostly on comparative analysis of governmental policies and social class dynamics. Second, critical perspectives that take into account racial inequalities are often not attuned to structural dynamics of gendered antiblackness, and instead present racism as a broad set of practices that negatively affect non-white people in related manners. Our context-specific analysis of the electoral reemergence of the far right in Brazil aims at contributing to an understanding of persistent dynamics of racial inequality within the region as part of a long, enduring and foundational odium of Black people.     

Predictive Soil Provenancing (PSP): An Innovative Forensic Soil Provenance Analysis Tool

Soil is a common evidence type used in forensic and intelligence operations. Where soil composition databases are lacking or inadequate, we propose to use publicly available soil attribute rasters to reduce forensic search areas. Soil attribute rasters, which have recently become widely available at high spatial resolutions, typically three arc‐seconds (~90 m), are predictive models of the distribution of soil properties (with confidence limits) derived from data mining the inter‐relationships between these properties and several environmental covariates. Each soil attribute raster is searched for pixels that satisfy the compositional conditions of the evidentiary soil sample (target value ± confidence limits). We show through an example that the search area for an evidentiary soil sample can be reduced to <10% of the original investigation area. This Predictive Soil Provenancing (PSP) approach is a transparent, reproducible, and objective method of efficiently and effectively reducing the likely provenance area of forensic soil samples.
