Abstract
The Western diet has undergone a massive switch since the second half of the 20th century, with the massive increase of the consumption of refined carbohydrate associated with many adverse health effects. The physiological mechanisms linked to this consumption, such as hyperglycaemia and hyperinsulinemia, may impact non medical traits such as facial attractiveness. To explore this issue, the relationship between facial attractiveness and immediate and chronic refined carbohydrate consumption estimated by glycemic load was studied for 104 French subjects. Facial attractiveness was assessed by opposite sex raters using pictures taken two hours after a controlled breakfast. Chronic consumption was assessed considering three high glycemic risk meals: breakfast, afternoon snacking and between-meal snacking. Immediate consumption of a high glycemic breakfast decreased facial attractiveness for men and women while controlling for several control variables, including energy intake. Chronic refined carbohydrate consumption had different effects on attractiveness depending on the meal and/or the sex. Chronic refined carbohydrate consumption, estimated by the glycemic load, during the three studied meals reduced attractiveness, while a high energy intake increased it. Nevertheless, the effect was reversed for men concerning the afternoon snack, for which a high energy intake reduced attractiveness and a high glycemic load increased it. These effects were maintained when potential confounders for facial attractiveness were controlled such as age, age departure from actual age, masculinity/femininity (perceived and measured), BMI, physical activity, parental home ownership, smoking, couple status, hormonal contraceptive use (for women), and facial hairiness (for men). Results were possibly mediated by an increase in age appearance for women and a decrease in perceived masculinity for men. The physiological differences between the three meals studied and the interpretation of the results from an adaptive/maladaptive point of view in relation to our new dietary environment are discussed.

Abstract
The current study compared physical aggression to factors affecting socioeconomic status in the accumulation of sex partners over the life course. Our data sample was drawn from the National Longitudinal Study of Adolescent to Adult Health (men, n = 5,636; women, n = 6,787). Participants were examined in terms of the number of lifetime sex partners they reported, nonrelationship partners, cheating or infidelity, and concurrent relationships. Intelligence and physical violence emerged as being especially likely to boost sex partner accumulation for the number of lifetime sex partners and nonrelationship partners in men. Intelligence also interacted positively with men's violence in cross-sectional models but not longitudinally. Women's violence was not significant regardless of the outcome or model specification. Intelligence showed less consistent effects for women's mating indicators compared to men. Analyses controlled for well-known correlates of aggression and sexual behavior and factors associated with beauty, including interviewer reports of survey participants' physical attractiveness and maturity, as well as self-reported attractiveness, maturity, and health. Findings are consistent with evolutionary ideas regarding costly signaling as an effective mating strategy among men.

Abstract
To fully understand human behavior, it seems inevitable to approach it from an evolutionary perspective. However, much of human behavior has been overwritten by culture and society, thus allowing little insight into how it might have evolved amid natural and sexual selection. Here, I argue that sports competitions, although a cultural phenomenon in themselves, strip away many of the cultural layers and reveal more primary, rudimentary aspects of human behavior. Fortunately, because they are ubiquitous, meticulously recorded, and often quantified in great detail, sports competitions provide a plethora of usable data. In this article I provide an evolutionary account of the cross-cultural existence and popularity of sports by reviewing evidence of four functional hypotheses that regard the omnipresence of sports as a by-product of fitness-related adaptations (skill acquisition and development, status seeking, courtship display, and coalition formation). Then I outline how the growing body of sports data and documentation can be exploited for increasing our understanding of human nature (e.g., on conflict and cooperation, lateral preferences, territoriality, and nonverbal communication). The article concludes by giving guidelines for future cross-disciplinary research to advance the understanding of how evolution has shaped human behavior.

Abstract
Taking an evolutionary psychological perspective, we investigated whether involvement in bullying as a perpetrator or victim was more likely if adolescents reported having more dating and sexual partners than their peers, an indication of greater engagement in competition for mates. A total of 334 adolescents (173 boys, 160 girls) between the ages of 12 and 16 years (M = 13.6, SD = 1.3), recruited from community youth organizations, completed self-report measures of physical and relational bullying and victimization, as well as dating and sexual behavior. As predicted, pure physical bullying was positively associated with the number of dating and sexual partners, primarily for adolescent boys. Adolescent girls with more dating partners had greater odds of being relational bully-victims, in line with predictions. Finally, adolescent girls with more sexual partners were at greater risk of being physically victimized by peers, and greater involvement with dating and sexual partners was associated with higher odds of being a physical bully-victim. Results are discussed with respect to evolutionary theory and research in which adolescent boys may display strength and athleticism through physical bullying to facilitate intersexual selection, whereas relational bullying may be employed as a strategy to engage in intrasexual competition with rivals for mates.

Abstract
Sexually active men, who are not in a monogamous relationship, may be at a greater risk for violence than men who are sexually active within monogamous relationships and men who are not sexually active. The current study examines changes in sexual behavior and violence in adolescence to early adulthood. Data on male (n = 4,597) and female (n = 5,523) respondents were drawn from four waves of the National Longitudinal Study of Adolescent and Adult Health (Add Health). HLM regression models indicate that men who transition to a monogamous, or less competitive, mode of sexual behavior (fewer partners since last wave), reduce their risk for violence. The same results were not replicated for females. Further, results were not accounted for by marital status or other more readily accepted explanations of violence. Findings suggest that competition for sex be further examined as a potential cause of male violence.

Abstract
RESUMO Introdução: Um dos maiores fenômenos esportivos na atualidade, o Ultimate Fighting Championship (UFC), realizado no Brasil em 2013, movimentou entre R$ 15 e R$ 50 milhões, destacando-se na mídia internacional. Apesar dessa superprodução dos eventos, os estudos com atletas de MMA (Mixed Martial Arts ) ainda são escassos, sobretudo no que se refere aos aspectos psicológicos. Objetivo: Analisar estratégias de coping, níveis de estresse e características de treinamento de atletas paranaenses de MMA. Métodos: Foram estudados 50 atletas de MMA do sexo masculino, com idade de 25,0 ± 4,8 anos. Como instrumentos foram utilizados uma ficha de identificação, o Inventário Atlético de Estratégias de Coping e o Questionário de Estresse e Recuperação para Atletas (RESTQ-76 Sport). Na análise dos dados, utilizou-se estatística descritiva, teste de Shapiro-Wilk, teste "U" de Mann-Whitnney; teste de Kruskal-Wallis e coeficiente de correlação de Spearman; a significância adotada foi p < 0,05. Resultados: Os atletas com principal fonte de renda no MMA apresentaram maior "estresse geral" (p = 0,023) e "estresse social" (p = 0,043) . Conclusão: Conclui-se que quando o esporte é a principal fonte de renda dos atletas, o estresse dos lutadores é elevado. Quanto maior o volume de treino, mais o atleta busca estabelecer objetivos e maior é sua a capacidade de confrontar as adversidades. Além disso, a variedade de estratégias de coping utilizadas pelos lutadores melhora seu estado de recuperação (capacidades físicas e psicológicas) durante as competições.

Abstract
Much evidence indicates that men experienced an evolutionary history of physical competition, both one-on-one and in coalitions. We thus hypothesized that, compared to girls and women, boys and men will possess a greater motivational predisposition to be interested in sports, especially team sports. According to most scholars, advocacy groups, and the United States courts, however, this hypothesis is challenged by modest sex differences in organized school sports participation in the contemporary U.S., where females comprise 42% of high school participants and 43% of intercollegiate participants. We conducted three studies to test whether organized school sports participation data underestimate the actual sex difference in sports participation. Study 1 analyzed the American Time Use Survey, which interviewed 112,000 individuals regarding their activities during one day. Females accounted for 51% of exercise (i.e., non-competitive) participations, 24% of total sports participations, and 20% of team sports participations. These sex differences were similar for older and younger age groups. Study 2 was based on systematic observations of sports and exercise at 41 public parks in four states. Females accounted for 37% of exercise participations, 19% of individual sports participations, and 10% of team sports participations. Study 3 involved surveying colleges and universities about intramural sports, which primarily consist of undergraduate participation in team sports. Across 34 institutions, females accounted for 26% of registrations. Nine institutions provided historical data, and these did not indicate that the sex difference is diminishing. Therefore, although efforts to ensure more equitable access to sports in the U.S. (i.e., Title IX) have produced many benefits, patterns of sports participation do not challenge the hypothesis of a large sex difference in interest and participation in physical competition.
