Possible associations of gender, age, and participation in volunteer activities with altruistic behavior of Chinese adolescents were investigated. A representative sample of 1,105 Hong Kong Chinese adolescents (457 boys, 648 girls) were recruited from 20 schools. Results of multiple regression analyses indicated that there was a positive age effect on altruistic behavior. In addition, a positiv...

Height growth velocity curves between 4.5 and 17.75 years were estimated, using smoothing spline functions, for 112 boys and 110 girls from the Zurich Longitudinal Study (1955--1976). Parameters characterizing the growth process, such as peak height velocity and age at peak height velocity, were calculated directly from the estimated curves. The variability of parameters describing the adolesce...

We designed and evaluated an objective structured biostatistics examination (OSBE) on a trial basis to determine whether it was feasible for formative or summative assessment. At Ataturk University, we have a seminar system for curriculum for every cohort of all five years undergraduate education. Each seminar consists of an integrated system for different subjects, every year three to six semi...

Several hypotheses on the form and function of sex differences in social behaviors were tested. The results suggest that friendship preferences in both sexes can be understood in terms of perceived reciprocity potential-capacity and willingness to engage in a mutually beneficial relationship. Divergent social styles may in turn reflect trade-offs between behaviors selected to maintain large, fu...

Gender may be involved in the motivational processing of facial beauty. This study applied a behavioral probe, known to activate brain motivational regions, to healthy heterosexual subjects. Matched samples of men and women were administered two tasks: (a) key pressing to change the viewing time of average or beautiful female or male facial images, and (b) rating the attractiveness of these ima...

We work from a life course perspective and identify several reasons to expect age and gender differences in the link between marital quality and health. We present growth curve evidence from a national longitudinal survey to show that marital strain accelerates the typical decline in self-rated health that occurs over time and that this adverse effect is greater at older ages. These findings fi...
