Type 2 Diabetes Mellitus and Cognitive Performance in a Population-Based Sample of the Oldest Old: Impact of Comorbid Dementia

We examined the relationship between type 2 diabetes mellitus and cognitive function in a population-based sample of very old people. The sample comprised 338 persons, aged 80-93 years (mean age 83.5 years), of whom 70 persons had type 2 diabetes mellitus. Measures of cognitive functioning included tests of perceptual speed, visuo-spatial ability, inductive reasoning, short-term memory, semantic memory, episodic memory, and the Mini-Mental State Examination. Regression analyses showed that type 2 diabetes mellitus duration was related to test performance across all cognitive domains, with the exception of short-term memory, such that longer duration was associated with lower test performance. When cases with dementia were excluded from the sample, further analyses showed that diabetes duration was not associated with cognitive test performance. This indicates that diabetes is not related to lower cognitive function in the general population of non-demented old people. Diabetes, however, increases the risk for cerebrovascular incidents, like stroke, that may contribute to vascular dementia.     

Relationships between ability and personality:does intelligence contribute positively to personal and social adjustment?

Intelligence/personality associations were studied in four large datasets. Correlations between general ability (g) and major personality traits were generally consistent with previous findings. For other traits, an interpretation of the correlation patterning is that traits classifiable as adaptive in terms of personal and social adjustment have positive correlations with g, whilst maladaptive traits have negative correlations. Regression modelling confirmed these associations and structural equation modelling of selected traits showed that Neuroticism acts as a mediator of g on the outcome. Non-linear relationships between intelligence and personality were not found. In two of the datasets the correlation between Neuroticism and Psychoticism decreased with ability level, and the correlation between fluid and crystallised ability increased with level of Neuroticism.     

Success and Gender: Determining the Rate of Advancement for Intercollegiate Athletic Directors

Since the demise of the Association for Intercollegiate Athletics for Women (AIAW), female sport administrators have continued their struggle to reestablish their place as athletic directors. The purpose of this study was to assess the rate of advancement (success ratio) of intercollegiate athletic directors, with a primary focus on gender. Athletic directors from 157 NCAA (National Collegiate Athletics Association) member institutions participated in the study. The preliminary results confirmed the expected findings that hegemonic masculinity was entrenched within intercollegiate athletics. The success ratio of male athletic directors differed from that of female athletic directors, and the difference was significant (p ≤ .05). The success ratio for men was higher than the ratio for women. Further analyses, however, showed that female athletic directors had higher success ratios than their male peers at lower level institutions. Although parity in numbers has not yet been achieved across the NCAA, the glass ceiling at Division I institutions may begin to crack as more women achieve success at the lower level institutions.     

Religious Ethics and the Environment

This essay discusses three recent books which each offer an integrative account of religious ethics and the environment. Religious environmental ethics is an area of inquiry within the larger field of religion and ecology. After a narrative that contextualizes the development of religious environmental ethics in relation to the environmental social movement, I describe the formation of the field including its focus on worldview, the “cosmological turn,” and its engagement with science, the “cosmic turn.” Elizabeth Johnson exemplifies the cosmic turn by developing a Christian theology of life in nature which explicitly accepts Darwin's theory of evolution. Willis Jenkins advocates a prophetic pragmatism and critiques a focus on worldview that is abstracted from practice and defers moral responsibility. Larry Rasmussen joins analysis of worldview with reflection on cross‐cultural resources for “anticipatory communities” of moral formation to catalyze change. I argue with Rasmussen that religious environmental ethics needs multiple approaches and should allow room for methodological pluralism.     

The role of personality in exposure and reactivity to interpersonal stress in relation to arthritis disease activity and negative affect in women.

The role of personality in the stress process was examined in older women with rheumatoid arthritis (RA) and osteoarthritis (OA) and in healthy controls (HCs). Reactivity was examined in relation to arthritis disease activity and negative affect. Interpersonal sensitivity and neuroticism were measured in questionnaires, and interpersonal stress, negative affect, and disease activity were assessed weekly for 12 weeks. Interpersonal sensitivity was defined as an excessive sensitivity to the behavior and feelings of others. Regarding exposure, neuroticism was related to interpersonal stress for all groups. Regarding reactivity, interpersonal sensitivity interacted with interpersonal stress to predicted elevations in negative affect in all groups and elevations in disease activity in the arthritis groups. There were no significant differences in the effects.
