The heritability of cognitive functioning in very old adults: evidence from Danish twins aged 75 years and older

Heritable influences on cognitive functioning were investigated in a sample of 403 pairs of like-sex Danish twins aged 75 years and older. Twins completed the Mini-Mental State Examination and 3 other cognitive tests. Genetic factors accounted for 26-54% of the variance on these measures, with the balance being due to environmental factors that create differences rather than similarities among reared-together relatives. Deleting twins with severe cognitive impairment had little effect on the results, indicating that the heritability of cognitive functioning was not due entirely to genes affecting dementia. Neither age nor gender moderated twin similarity, and differential social contact could not account for correlation differences between monozygotic and dizygotic twins. These results replicate G. E. McClearn et al.'s (1997) study in indicating substantial genetic influences on late-life cognitive functioning.     

ANTECEDENT FACTORS DIFFERENTIATING WOMEN AND MEN IN SCIENCE/ NONSCIENCE CAREERS

Factors that differentiate women and men who choose a science career from those who do not were investigated using longitudinal data from 1980 and 1990. The participants (N = 459) were ninth or twelfth graders at six midwestern high schools in 1980. Women in science compared to women in other careers were significantly more likely to value math and science for their future career goals, whereas men in science compared to men in other careers had significantly higher high school grade point averages in natural science and higher career aspirations. Not unexpectedly, both women and men in science careers compared to those in nonscience careers took more high school elective science courses because they wanted to, aspired to higher prestige careers as young adults, and attributed their math successes more to their ability. The male model accounted for more than twice the variance accounted for by the female model, and context variables were not predictive for either model. Suggestions for revising the model and improving the assessment of context influences are made. Implications for research and practice include designing and evaluating programs to increase the number of intellectually able girls valuing math and science as these relate to their future goals.

Balancing the ledger: An application of Nagy's theories to the study of continuity and change among generations

This study uses an interpretive interview method to examine the micro-processes of generational continuity and change among a group of social activists. Boszormenyi-Nagy's theory of responsibility between generations, alternative models outside the family, and choice are used to explain the instances of change. Implications for research and practice are addressed.     

Wilderness family therapy: Experiential dimensions

This paper describes the process in which families participate in a wilderness experience. Metaphors such as climbing or paddling a canoe are translated into daily living patterns to deepen individual and family self-knowledge, self-esteem, and intimacy.     

Interventions With Juvenile Offenders: Strategies to Prevent Acting Out Behavior

In this article Moral Dilemma Discussion Groups, Just Communities, Positive Peer Culture and the EQUIP program are reviewed for their appropriateness for intervening with juvenile offenders in residential settings. The suitability of these interventions for diverse populations is also examined.
