SEX DIFFERENCES AND DEPRESSION IN PUERTO RICO

Sex differences in rates of depressive disorders and depressive symptomatology, as measured by the Diagnostic Interview Schedule, are examined for an island-wide probability sample of Puerto Rico. Consistent with previous research, depression is significantly more prevalent in Puerto Rican women than men. Risk factors associated with depressive symptomatology are examined from a sex-role perspective. The results of multiple regression analyses show that even after demographic, health and marital and employment status variables are controlled, women continue to be at higher risk of depressive symptomatology than men. These results are interpreted within a cultural and sex-role perspective.     

Adolescents' use of affiliative and aggressive strategies during conflict with romantic partners and best-friends

Objective: Developmental theory suggests romantic relationships present unique demands when adolescents transition from the interaction patterns of same-sex friendships to cross-gender interactions. A possible response is to incorporate behaviours of the other gender: girls adopting aggressive strategies and boys adopting affiliative ones. The goal of this study is to explore this hypothesis by comparing conflict resolution among romantic couples and same-sex best friends. Method: Observational methods were employed with 37 female best friends, 22 male best friends and 37 romantic couples. Of the romantic couples, 35 also were observed with a best friend. Affiliative and aggressive behaviours were tabulated during two conflict tasks. Results: Female best friends were more affiliative than male best friends and romantic partners; these latter dyads were more aggressive than the female best friends. Within group comparisons indicated that boys and girls decreased their affiliative behaviours, especially verbal humour, and increased their aggressive behaviours, especially teasing, when observed with the romantic partner compared to the best friend. Decomposing the romantic dyad, girlfriends displayed relatively more aggressive behaviours than their boyfriends, and boyfriends exhibited more affiliative behaviours. Conclusions: Findings shed light on gendered shifts in patterns of interaction as adolescents transition from same-sex friendships to romantic relationships.     

Text Genre and Science Content: Ease of Reading,Comprehension, and Reader Preference

This study examined ease of reading, comprehension, and recall and preference for the same scientific content under two conditions: an informational text and a fictional narrative text. Seventy-four third and fourth graders were assessed individually around the reading of fictional narrative and informational texts that were about either snails or sand. Students’ accuracy and rate of reading were comparable across the two genres. However, students answered more comprehension questions correctly and recalled more key concepts in response to informational text than fictional narrative text. Moreover, students did not express a clear preference for one type of text over the other.     

Correlates of suicide in the older adult population in Quebec

This study was undertaken to describe the characteristics of adults aged 60 years and over who committed suicide in Quebec in 1998-1999. In this study, 42.6% of the suicide cases presented mental disorders at the time of their death, mainly depression. Sixty-five (65.3%) percent of the suicide cases would have been considered as having a mental health disorder if sub-threshold depression cases were included. Only 27.7% of the cases did not express any idea of death during the 6-month period preceding their suicide. One interesting finding was that 53.5% of the suicide cases consulted a general practitioner or specialist during the 2-week period preceding their death. Our results showed that only 8.1% had a severe level of functional limitations at the time of their death. This result leads us to interpret with caution the conclusion of some studies suggesting that physical frailty is a major causal factor associated with suicide among the elderly.     

Preattentive vision and perceptual groups

Recent evidence suggests that preattentive processing may not be limited to the analysis of simple stimulus features as previously suggested. To explore this idea a visual search task was used to test whether the shapes of several perceptual groups can be processed in parallel. Textured displays that give rise to strong perceptual grouping were used to create figures on a background. Search times for a target figure distinguished by a unique shape were found to be independent of the number of distractor figures in the display. This result indicates that perceptual groups may be processed in parallel and suggests an expanded role for preattentive processing in vision.     

A loss of status and a sense of defeat: an evolutionary perspective on professional burnout

This longitudinal study among Spanish teachers (N = 558) examined burnout from an evolutionary social rank perspective. The types of stress differed among various school levels, and a sense of defeat was highest among teachers in primary schools. A low status, a loss of status and a sense of defeat were independent cross‐sectional predictors of burnout. Longitudinally a sense of defeat predicted an increase in burnout over time, especially among males and teachers in high schools. The status related variables were in general more important predictors of burnout than stressors that are usually associated with burnout. Copyright © 2007 John Wiley & Sons, Ltd.     

Gender differences in alcohol dependence: personality variables, psychopathological profile and personality disorders

In this paper, gender differences in personality, psychopathology and personality disorders of alcohol-dependent patients are described. The sample consisted of 158 alcohol-dependent patients attending a psychiatric outpatient clinic (105 men and 55 women). All participants were assessed with various assessment tools related to personality (Impulsiveness Scale, Sensation Seeking Scale and STAI), psychopathology (SCL-90-R, BDI and Inadaptation Scale) and personality disorders (IPDE). There were no differences in personality variables, but the women had more anxiety and depressive symptoms and also more problems to adapt to everyday life than did the men. Personality disorders were not as prevalent as in the case of men, and the most frequent among women were obsessive-compulsive, dependent and histrionic personality disorders. Implications of this study for further research are commented on.     

Aggression inhibition in high‐ and low‐risk subjects for child physical abuse: effects of a child's hostile intent and the presence of mitigating information

Exposure of an aggressor to the suffering of his/her victim generally inhibits subsequent attacks [e.g. Baron, 1971a] presumably because of an empathic process. Physically abusive parents and individuals at high risk for child physical abuse are thought to present a deficit in empathy [e.g. Milner, Halsey and Fultz, 1995]. The present research was designed to investigate whether high‐risk, compared to low‐risk, subjects for child physical abuse select more aggressive responses and aggress with more intensity toward a supposed child whose behavior is adequate, inadequate or ambiguous in the presence of the child's pain cues. A second objective was to explore whether high‐risk, compared to low‐risk, subjects for child physical abuse fail to adequately integrate mitigating information and, therefore, do not inhibit their aggressive behavior following the receipt of mitigating information before or during an inadequate child behavior. Participants were engaged in an experimental task that involved attempting to teach a child how to proceed accurately through a computer‐displayed maze and were given the opportunity to send positive (pleasant sounds and happy faces) and negative feedback (mad faces and unpleasant sounds) to the child. Two hundred and fifty undergraduate students participated in the experiment. A 2 × 5 factorial design based on two levels of the participant's risk status (high, low) and five conditions based on the child's behavior and the introduction of mitigating information was employed. As expected, low‐risk, compared to high‐risk, subjects showed less aggression when mitigating information was provided. Aggr. Behav. 32:1–15, 2006. © 2006 Wiley‐Liss, Inc.     

Portfolio Selection from Multiple Benchmarks: A Goal Programming Approach to an Actual Case

This paper deals with benchmark‐based portfolio choice for buy‐and‐hold strategies of investing. Multiple benchmarks for returns are considered, which is more realistic than taking a unique benchmark – a unique aspiration difficult to select in practice among the various aspirations for returns that the investor has in mind. Portfolio selection with multiple benchmarks leads to a multi‐objective problem, which is addressed by mean value – stochastic goal programming. In particular, two benchmarks are considered, which involves two goals. Weights for goals depend on investor's preferences and Arrow's absolute risk aversion coefficients. An efficient frontier of portfolios is obtained. Advantages of this stochastic method in our context are as follows: (i) Mean value‐stochastic goal programming relies on classical utility theory under uncertainty and Arrow's absolute risk aversion, which ensures soundness and strictness, and (ii) the numerical model is easily solved by using available software such as mean–variance software. Numerical results are tabulated and discussed. Copyright © 2011 John Wiley & Sons, Ltd.
