Body Mass Index, suicide, and homicide among inhabitants of the Caribbean Islands

To test the hypothesis that the more overweight and obese a nation, as measured by Body Mass Index, the greater the risk of suicide; mean scores of Body Mass Index for males and females over 15 years of age in 11 Caribbean Islands were not associated with either male or female rates of suicide or homicide with one exception, i.e., when controlling for gross domestic product per capita, mean Body Mass Indices for males were significantly and negatively associated with male rate of homicide.     

Turnover of highly educated R&D professionals: The role of pre‐entry cognitive style,work values and career orientation

Retention of key R&D experts has been recognized as a critical managerial challenge for many technology‐based companies. In this study, we propose that turnover of highly educated professional workers is meaningfully related to individual characteristics such as cognitive style, work values and career orientation. We tested the hypotheses using data collected from a sample of 132 R&D professionals with PhD degrees in engineering or natural science in a Korean electronics firm. The time‐dependent risk of turnover was estimated by survival analysis using a proportional hazards regression model. The results showed that over the 7‐year period after their organizational entry, R&D professionals with high levels of intrinsic values and cosmopolitan orientation were more likely to leave the organization than were their counterparts with low levels of intrinsic values and cosmopolitan orientation. The hazard function showed that the positive effect of intrinsic work values on turnover was particularly salient in the third and fourth year of R&D professionals' organizational tenure. We found that the positive effect of cosmopolitan orientation on turnover increased over time, introducing a greater risk of turnover with increasing tenure. The present findings have practical implications for the retention of highly educated R&D professionals in a corporate setting.     

Immigrant youth of Indian origin: Generational differences in self-critical perfectionism

A community sample of foreign-born first generation (n = 53) and U.S.-born secondgeneration (n = 57) youth of Indian origin (ages 18–25) was studied. Variables predicting self-critical perfectionism were perceived prejudice, enculturation, and communication difficulty with parents and their interaction with generation status. The differences between the two generations pointed to nuanced self-pressures of Indian immigrant youth, despite good academic standing and middle-class family income. Implications discuss counseling with Indian immigrant youth.     

Continuous Cognitive Tasks Improve Postural Control Compared to Discrete Cognitive Tasks

Research suggests that postural control synergies are sensitive to cognitive manipulations; however, the impact of different types of cognitive tasks on postural control remains inconclusive. The authors examined the effect of discrete and continuous tasks on postural control. Sixteen healthy young adults (M age = 22.7 ± 2.2 years) stood with feet together on a force platform while performing randomly assigned discrete and continuous cognitive tasks. Results demonstrated marked improvements in the area of 95% confidence ellipse and the standard deviation of the center of pressure in the anterior-posterior and medial-lateral directions for continuous compared to discrete tasks. This reinforces the notion that continuous tasks are sufficient in providing less opportunity to consciously attend to postural control, thereby facilitating automatic postural control.     

Item-response theory modeling of IQ gains (the Flynn effect) on crystallized intelligence: Rodgers' hypothesis yes,Brand's hypothesis perhaps

Potential explanations for generational intelligence test score gains continue to be subject to intense debate and scrutiny in the scientific community. However, the explanatory value of some of the proposed causes remains difficult to determine, since only little empirical evidence is available. To clarify the role of two scarcely investigated theories accounting for the Flynn effect, this study set out to examine the role of changing test-taking behavior (Brand's hypothesis) and of a narrowing of the IQ ability distribution (Rodgers' hypothesis). Archival records of crystallized intelligence test performance over a time-span of 17 years of a large number of psychiatric inpatients and outpatients in Austria were investigated (N = 5445; 1978–94). This sample was particularly suitable to investigate our hypotheses since participants were under no pressure to perform which makes observed changes in test taking behavior attributable to personal style and ability rather than differential performance in pressure situations. Analytical approaches of both classical test theory and item response theory (IRT) yielded gains of 1.0 to 2.4 IQ points per decade. Test-taking behavior indicative of guessing and decreasing population IQ variability appeared to contribute both to IQ test score gains. IRT-based analyses showed that gains were largely preserved when controlling for highest educational qualification, while the test instrument showed measurement invariance between cohorts. However, IRT-based results also suggested that changes in test-taking behavior might not necessarily reflect increased guessing, but item drift instead. In all, this evidence emphasizes better performance of individuals of the lower tail of the IQ ability distribution in more recent years as one important contributing factor for generational IQ test score gains.     

Rumination and intentional forgetting of emotional material

The tendency to respond to negative life events and negative mood states with ruminative thinking has been linked to emotion dysregulation and to a heightened risk for the onset and maintenance of emotional disorders. To further investigate this maladaptive response style, the present study examined whether rumination is linked to individual differences in the ability to intentionally forget emotional material. In a directed forgetting task, participants were instructed to memorise a list of positive and negative words and were subsequently told to forget these words. Next, participants were told to memorise a new list and, finally, recall was tested for all to-be-forgotten and to-be-remembered words. Our results demonstrate a close relation between rumination and recall in the forget condition but not in the remember condition. Specifically, compared to participants who scored low on the Ruminative Responses Scale (RRS), participants who scored high exhibited reduced forgetting of positive and negative to-be-forgotten words. These results remained stable when depression scores were included as a covariate suggesting that irrespective of depressive symptoms, rumination and intentional forgetting of emotional material are closely related.     

Community Mobilization and Community-Based Participatory Research to Prevent Youth Violence Among Asian and Immigrant Populations

Many community mobilization activities for youth violence prevention involve the researchers assisting communities in identifying, adapting, and/or tailoring evidence-based programs to fit the community needs, population, and cultural and social contexts. This article describes a slightly different framework in which the collaborative research/evaluation project emerged from the community mobilization activities. As will be discussed, this collaborative, sustained partnership was possible in the context of the Center on Culture, Immigration and Youth Violence Prevention's (UC Berkeley ACE) community mobilization activities that brought the issue of youth violence, particularly among immigrant and minority populations, to the forefront of many of the community partners' agendas. The East Bay Asian Youth Center (EBAYC) was one of the partners that came to the table, which facilitated the community-based engagement/mobilization. UC Berkeley ACE collaborated with EBAYC to evaluate an after-school program and an alternative probation program serving a diverse youth and immigrant population, including African Americans, Asians, and Hispanics. This article describes UC Berkeley ACE's community mobilization activity and the collaborative partnership with EBAYC, discusses how the evaluations incorporated community-based principles in design and practice, and presents some findings from the evaluations.     

Gender Stereotypes Depicted by Western and Korean Advertising Models in Korean Adolescent Girls�� Magazines

Using content analysis based on Goffman??s (1979) typology, the authors examined gender role stereotypes in Korean fashion magazines targeting adolescent girls. Korean women were more stereotypically portrayed than any other group as smiling, pouting, and with a childlike or cute expression. On the other hand, Western women were more stereotypically portrayed than any other group in the categories of licensed withdrawal and body display. In some categories, male models were more female-stereotypically portrayed than female models of a particular race. Implications of the findings, future research suggestions, and limitations of the current study are discussed.
