RESUMEN
Prior research finds that sex ratio, defined as the proportion of males and females in a given context, is related to engagement in risk-taking behaviors. However, most research operationalizes sex ratio at a local context (e.g., regional or county), which fails to reflect with precision the sex ratios contexts of individuals at a closer level. Furthermore, the relationship between sex ratio and risk-taking behaviors may be affected by individuals' life history strategy, with previous studies showing fast life history strategies linked to risk-taking behaviors, compared to slow life history strategies. The present study analyzes the relationship between classroom sex ratio and risk-taking behaviors and the interaction between classroom sex ratio and life history strategy in adolescents. The sample comprised 1214 participants nested in 57 classrooms, 49.75% females, 91.5% Spanish and a mean age of 16.15 years (SD = 1.23, range 14-21). Results from multilevel modeling showed a negative relation between classroom sex ratio and risk-taking behaviors in female adolescents with faster life history strategy. By contrast, classroom sex ratio in male adolescents related positively to risk-taking behaviors but did not interact with life history strategy. These findings underscore the importance of studying proximate sex ratio on risk-taking behaviors in adolescents and underline its potential influence in the development and expression of life history strategies.

Background: International migration processes are some of the most important events of our time. Migrating implies a broad range of factors that affect integration, and which may be linked to radicalization. Host countries use different methods for the integration of migrants. The aim of this systematic review is to analyze intervention programs that aim at promoting social integration and preventing the radicalization of migrants, with the objective of studying actions carried out in the US, Canada, and Europe to this effect. Method: Worldwide known bibliographic databases (PsyCINFO, Sociological Abstracts, Psycarticles, Psychology Database, Medline, SCOPUS, and Google Scholar) were used to search studies published before January 2019 and which analyzed integration or radicalization prevention programs with migrants. Results: A total of 601 studies were screened, from which 18 met the inclusion criteria. The analysis of programs addressed to migrant women points to a decrease in loneliness and depression and an increase of migrants' perception of social support and self-esteem. Programs carried out in schools and families improve children's knowledge of their culture and that of others, increase their feelings of inclusion, and reduce their aggressiveness, stress, and anxiety. Language programs promote communication and employment search, as well as improve migrants' quality of life. One of the most effective activities included in these programs is to connect recently arrived migrants with local population and/or long-term residents. The latter act as mentors and teachers, helping recently arrived migrants understand resources and to be more integrated in the new country, as well as reducing discrimination from the local population. Conclusions: The review concluded the importance of intervention programs for integration, migrants' quality of life, prevention of extreme behaviors, and intercultural cohabitation. Future programs must be more detailed regarding participants' information and carry out more comprehensive assessments.
RESUMEN
Risk-taking behaviors in adolescents have traditionally been analyzed from a psychopathological approach, with an excessive emphasis on their potential costs. From evolutionary theory we propose that risk-taking behaviors can be means through which adolescents obtain potential benefits for survival and reproduction. The present study analyses sex differences in three contexts of risk (i.e., risk propensity, expected benefits and risk perception) in the evolutionary specific domains and the predictive value of these domains over risk-taking behaviors, separately in female and male adolescents. 749 adolescents (females = 370) valued their risk perception, expected benefits and risk propensity through the Evolutionary Domain-Specific Risk Scale, as well as their engagement in risk-taking behaviors through the Risky Behavior Questionnaire. Male adolescents showed lower risk perception in two evolutionary domains, expected higher benefits in two other domains and showed higher risk propensity in six domains. Female adolescents showed lower risk perception in two domains. Additionally, risk perception, expected benefits and risk propensity in the evolutionary domains predicted the engagement in risk-taking behaviors in male adolescents, whereas in female adolescents only expected benefits and risk propensity showed a predictive effect over risk-taking behaviors. These results suggest the potential role of evolutionary mechanisms on risk-taking behaviors in adolescents. Results have practical implications for interventions programs aimed at reducing risk-taking behaviors. In addition to considering sex differences, intervention programs should consider alternative behaviors through which adolescents can reach their evolutionary goals, and handle the risks related to those behaviors that cannot be replaced but have potential benefits for adolescents.
RESUMEN
This study analysed the association between discrimination and satisfaction with life (SWL) in migrant groups by investigating whether different types of social support (SS; emotional, instrumental, and informational) and networks (family, immigrant and native friends, neighbours, and the community) buffer the negative effects of discrimination on SWL among migrant men and women from different backgrounds. Participants were 631 migrants from Latin America and China residing in Malaga (Spain). We identified behaviour patterns that suggest that SS has different effects on men and women from the same place of origin and similar effects on women and men from different places of origin. In conclusion, the main differences in the effects of SS as a buffer mechanism are not determined by cultural factors. It is more likely that they are determined by differential gender-role socialization, which would lead women to positively value social support.
