New perspectives in historical demography in Latin America

The author outlines developments in the field of historical demography in Latin America. Methodological and theoretical aspects are evaluated, with a focus on the study of aggregate vital series and in-depth analysis of census data. The importance of integrating demographic analysis with social and economic history is emphasized.     

Suicide prevention on college campuses: What works and what are the existing gaps? A systematic review and meta-analysis

Abstract

Objective: To examine the effects of universal and targeted suicide prevention programs on relevant outcomes in college campuses. Methods: College suicide prevention programs published from 2009 to 2018 were assessed on outcomes including knowledge, skills, self-efficacy, suicidal ideation, and suicidal behaviors. Effects of the interventions on outcome variables with sufficient studies to warrant meta-analysis (ie, knowledge, skills, and self-efficacy) were meta-analyzed. Studies reporting on the remaining outcomes (ie, suicidal ideation and behaviors) were systematically reviewed. Results: Significant increases in suicide prevention knowledge, skills, and self-efficacy were observed in universal prevention interventions that typically employed gatekeeper prevention strategies. Evidence of reductions in suicidal ideation and behaviors was observed across targeted suicide prevention programs for at-risk students. Conclusion: Prevention programs are beneficial for training those likely to come in contact with people endorsing suicidality, but further research is needed to show that suicide interventions can consistently have significant effects on suicidal students as well.     

Linguistic Acculturation and Context on Self-Esteem: Hispanic Youth Between Cultures

Immigrant adolescents must negotiate two cultures: the host culture and their native culture. This study explored how self-esteem is moderated by the effect of linguistic acculturation and context. An ordinary least-squares regression model, controlling for fixed effects, produced results supporting the hypothesis that linguistic acculturation moderates the effect of context on self-esteem. The self-esteem of Hispanic adolescents who were less linguistically acculturated was found to be more favorable when with family than with friends and the reverse was found for the more linguistically acculturated participants. Adolescents in the middle of the linguistic acculturation process had the widest variance in self-esteem between times they were with their families and times in other contexts; they experienced more positive self-esteem with anyone but family. Findings underscore the need to better understand the complex process of linguistic acculturation and its effects on self-esteem. This research also demonstrates the practical utility of a fixed-effects model for reducing bias in cross-cultural research.     

Comparative assessment of analytical approaches to quantify the risk for introduction of rare animal diseases: the example of avian influenza in Spain

Trade of animals and animal products imposes an uncertain and variable risk for exotic animal diseases introduction into importing countries. Risk analysis provides importing countries with an objective, transparent, and internationally accepted method for assessing that risk. Over the last decades, European Union countries have conducted probabilistic risk assessments quite frequently to quantify the risk for rare animal diseases introduction into their territories. Most probabilistic animal health risk assessments have been typically classified into one-level and multilevel binomial models. One-level models are more simple than multilevel models because they assume that animals or products originate from one single population. However, it is unknown whether such simplification may result in substantially different results compared to those obtained through the use of multilevel models. Here, data used on a probabilistic multilevel binomial model formulated to assess the risk for highly pathogenic avian influenza introduction into Spain were reanalyzed using a one-level binomial model and their outcomes were compared. An alternative ordinal model is also proposed here, which makes use of simpler assumptions and less information compared to those required by traditional one-level and multilevel approaches. Results suggest that, at least under certain circumstances, results of the one-level and ordinal approaches are similar to those obtained using multilevel models. Consequently, we argue that, when data are insufficient to run traditional probabilistic models, the ordinal approach presented here may be a suitable alternative to rank exporting countries in terms of the risk that they impose for the spread of rare animal diseases into disease-free countries.     

Couples' Views about Planning Fertility in the Philippines*

Abstract This research examines Filipino couples' attitudes toward the occurrence and timing of their most recent pregnancies. Differences between processes operating in rural and urban areas are highlighted. Specific topics include the role of couples' fertility preferences in predicting the intention status of pregnancies, the effect of personal agency in decision making about contraception and childbearing, and whether women who are better able to communicate with their husbands about sex and related matters are more able than other women to avoid unintended births. These topics are explored through survey data and in‐depth interviews.     

Studying improved performance in golf

The topic of improved performances by athletes in both team and individual sports has shown that each sport has its own unique set of characteristics and these have to be analysed accordingly. This paper presents an extensive analysis of the nature and extent of improvement in golf by analysing the performances of the top players in the Masters tournament throughout the entire history of the event. The results indicate that golfers are obtaining lower scores over time and that the variation of the scores has declined. Further, the distributions of scores are symmetric and display a monotonic reduction of peakedness (kurtosis). These findings are indicative of rapid and improved performance and increased competition.     

Unexpected Caregiving in Later Life: Illuminating the Narratives of Resilience of Grandmothers and Relative Caregivers through Photovoice Methodology

ABSTRACT

This research study implements photovoice methodology with unexpected caregivers to illuminate the lived experiences of female grandparents and relative caregivers who are raising young children in the later stages of their life. As they enter older adulthood, grandmothers are increasingly finding themselves taking care of their children’s children for various reasons, including, but not limited to, their adult child’s incarceration, mental health issues, drug and alcohol addiction, or child abuse or neglect. Informed by various feminist theoretical lenses, we use photovoice methodology to highlight the narratives of resilience and explore the ways in which grandmothers re-conceptualize their roles and identity as an unexpected caregiver and the sources of strength and resilience that inform the ways in which they navigate the various circumstances in their lives.     

College Student Psychological Distress: Relationship to Self‐Esteem and Career Decision Self‐Efficacy Beliefs

College students experience a number of stressors, such as adjustment to a new environment, postgraduation planning, and the balancing of changing roles and responsibilities. These stressors may contribute to increased rates of psychological distress that have implications for their educational and career development. The purpose of this study was to extend understanding of the nature of the relationships among psychological distress, self‐esteem, and career decision self‐efficacy (CDSE) beliefs. Results from 292 undergraduate students demonstrated support for the proposed hypotheses. Psychological distress negatively related to self‐esteem and to CDSE. Self‐esteem was positively related to, yet distinct from, CDSE, and both self‐esteem and psychological distress contributed unique variance to the prediction of CDSE. Results highlight the importance of attending to student psychological distress in the provision of career counseling services. Future research that centralizes mental health is needed to better understand relationships among career development processes over time and within diverse student populations.
