Follow-up of 812 girls 10 years after high school dropout.

Compared a droupout group and nondropout group on several variables. The data both predated and postdated the time of school dropout. For analysis the groups were subdivided on time of marriage and intelligence. Dropouts have a higher separation and divorce rate, even when time of marriage is controlled; they have larger families, but apparently only because they have been married longer. In general they marry into a lower socioeconomic status, but only girls from blue-collar families show a downward social mobility. When grouped by intelligence, high and medium intelligence dropouts do not show the upward social mobility that nondropouts do. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Social context as a determinant of sex differences in adults' attraction to infants.

70 male and 70 female undergraduates in same- or mixed-sex groups publicly or privately judged pictures of subhuman primate infants and adults for attractiveness. Sex differences were significant but the largest difference between males and females was found when judgments were made in public same-sex groups. Females reported greater attraction to infants relative to their attraction to adults, when judgments were made publicly in all-female groups. Males reported less attraction to infants in all-male public groups than when in private. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Perception, attitudes and beliefs, and openness to change: implications for older driver education

With a rapidly aging population, strategies for improving driver safety are beginning to emerge that focus on changing driving behaviors and knowledge. We examined the perceptions of risk, beliefs and attitudes, and openness to change of 86 older participants voluntarily attending a driver education program. It appeared that most people attending these sessions were not necessarily concerned about their own driving, safety or abilities, but were interested in maintaining mobility. They were conservative and reasonably consistent in their attitudes toward traffic regulations and safe driving practices. Some gender differences emerged with more men than women being resistant to changing their driving habits, more men than women reporting that they drive after consuming alcohol and more women than men identifying a role for their families in decision-making regarding driving cessation. This suggests that educational material may need to be targeted differently for men and women. It is anticipated that psychosocial factors related to driving such as driver perception, beliefs and openness to change will be useful for maximizing the fit between education program content and outcomes.     

Impact of social environment on variation in menstrual cycle length in captive female olive baboons (Papio anubis)

Factors affecting menstrual cycles and conception were explored for captive female olive baboons. We evaluated the relationship between the social environment and adequacy of the menstrual cycle in 55 non-conceptive and 21 conception cycles from 23 females. More abnormal cycles were expected for low-status females, and social stress levels were associated with variation in menstrual cycle length. Mean cycle length was 39.9 days (median=38) with a mean follicular phase duration of 23.7 (median=22) days. The duration of the follicular phase was more variable than that of the luteal phase (mean=15.8 days). The first cycle after postpartum resumption of cycling was not markedly different from subsequent cycles in terms of duration or probability of conception. Dominance rank was one significant factor affecting female fertility. Low-ranking females experienced more cycles prior to conception, longer cycles once cycling was well established and had smaller sexual swellings (anogenital area) than did high-ranking females. Both acute and chronic stresses may play important roles in fertility outcomes for these baboons and further research is needed to understand the role of stress and subtle menstrual cycle abnormalities in female mammal fertility.     

Correlations of dietary patterns with prostate health

Both genetic and environmental influences may be involved in etiology of prostate health and prostate cancer. These include ethnic origin, family history, smoking, and diet. Adiposity and excess energy intake are potentially distinct risk factors and positive associations with prostate cancer risk for both were observed among case-control and cohort studies. Some epidemiological studies support an association between dietary fat, particularly saturated or animal fats, and prostate cancer risk. Of these, several suggest reduced risk with low-fat diets high in n-3 fatty acids and increased risk with high-fat diets rich in n-6 fatty acids. Others suggested association with higher meat intake, possibly due to heterocyclic amines and polycyclic aromatic hydrocarbons, produced during grilling or frying. Positive association of prostate cancer risk with dairy intake could involve alpha-methylacyl-CoA racemase activity (required for beta-oxidation of phytanic acid present in dairy products and red meat) or the suppression of vitamin D activity by calcium. Inverse associations were observed with dietary intake of plant foods. These include cereals, soy products, and fruit and vegetable sources of carotenoids. Numerous plant constituents may act synergistically in the prevention and inhibition of prostate disorders. These diet-risk associations may lead to future individualized diet recommendations based upon genetic polymorphisms.     

A partitioning advisory system for networked data-parallel processing

With the increased performance capabilities of desktop computers, networked computing has become a popular vehicle for using parallelism to solve a variety of computationally intense problems. However, node heterogeneity and high communication costs may limit performance unless the problem space is carefully partitioned across the network in a way that considers both the capabilities of the machines and the high network communication costs. We describe an advisory system that is designed to help the programmer, compiler or run-time environment choose the best decomposition strategy for partitioning specific data-parallel applications across a given collection of machines. The system includes provisions for assessing the capabilities of the participating machines and the network in light of the current workload. Given information about the problem space, the machine speeds and the network, the system provides a ranking of three standard partitioning methods. We test the validity of our system by comparing the observed relative performance with predicted relative performance of different data decompositions on a program with a variable number of floating point operations and a 5-point stencil communication pattern.     

Impact of child-centered play therapy on the self-esteem, locus of control, and anxiety of at-risk 4th, 5th, and 6th grade students.

Addresses the impact of child-centered play therapy on the self-esteem, locus of control, and anxiety level of at-risk 4th, 5th, and 6th grade children. The two groups of students, those who participated in play therapy and those who did not participate in play therapy, were administered the Coopersmith Self-Esteem Inventory, Intellectual Achievement Responsibility Scale—Revised, and State-Trait Anxiety Inventory for Children. While the results indicate that children participating in play therapy did not change, the students not participating in play therapy demonstrated a decrease in both self-esteem and locus of control over the course of the school year. These findings indicate that an intervention, such as play therapy, may be needed to prevent at-risk children from developing lower self esteem and from reducing their sense of responsibility for their academic successes and failures.
