The Effect of War Stressors and Life Events on Gulf War Veterans With Chronic Fatigue Syndrome Symptoms

This study examines the association of life stressors and the period when they occur, with the development of chronic fatigue syndrome (CFS) symptoms in Gulf War veterans. Of data collected from Gulf War Health Registry veterans, 113 met CFS criteria and 441were controls. After hierarchical multiple regression, several negative life stressors were associated with CFS group membership: being wounded, experiencing a traumatic war experience, frequent battle experiences, demotion, and unable to work within 2 years of returning from the Gulf. The positive life stressor of buying a house more than 2 years after returning protected against being in the CFS group. The findings are consistent with etiological hypotheses of CFS incorporating a psychosocial component and are useful in developing programs for veterans returning from war.     

Reasons and Causes

Abstract: This paper argues for a causal‐psychological account of acting for reasons. This view is distinguished from a more ambitious causal theory of action, clarified as far as possible, and motivated—against non‐reductive, teleological, and behaviourist alternatives—on broadly metaphysical grounds.     

Attractiveness of own-race, other-race, and mixed-race faces

Averaged face composites, which represent the central tendency of a familiar population of faces, are attractive. If this prototypicality contributes to their appeal, then averaged composites should be more attractive when their component faces come from a familiar, own-race population than when they come from a less familiar, other-race population. We compared the attractiveness of own-race composites, other-race composites, and mixed-race composites (where the component faces were from both races). In experiment 1, Caucasian participants rated own-race composites as more attractive than other-race composites, but only for male faces. However, mixed-race (Caucasian/Japanese) composites were significantly more attractive than own-race composites, particularly for the opposite sex. In experiment 2, Caucasian and Japanese participants living in Australia and Japan, respectively, selected the most attractive face from a continuum with exaggerated Caucasian characteristics at one end and exaggerated Japanese characteristics at the other, with intervening images including a Caucasian averaged composite, a mixed-race averaged composite, and a Japanese averaged composite. The most attractive face was, again, a mixed-race composite, for both Caucasian and Japanese participants. In experiment 3, Caucasian participants rated individual Eurasian faces as significantly more attractive than either Caucasian or Asian faces. Similar results were obtained with composites. Eurasian faces and composites were also rated as healthier than Caucasian or Asian faces and composites, respectively. These results suggest that signs of health may be more important than prototypicality in making average faces attractive.     

Factors Predicting Intention to Enroll in a Philosophy of Life Course

This research examined factors predicting university students' intentions to enroll in a philosophy of life course. One hundred and ninety subjects participated in two surveys. The first was qualitative, identifying factors students considered in forming intentions, but without ranking the factors. The second study used a quantitative model to predict student intentions from their beliefs about the course, themselves, and other people. The model was based on Ajzen's theory of planned behavior, a theory that successfully predicts many different behaviors. Analysis was done using partial least squares, a robust structural equation modeling technique. The results show that students focused primarily on personal outcomes from the course. They wanted the course to help them understand life and themselves. To a lesser extent, students' perceptions of other people's views affected their intentions, especially the opinions of parents, friends, and religious people. Some students thought all beliefs are subjective, and discussing them would be pointless. Recommendations are given for designing and promoting philosophy of life courses.     

Parfit on Direct Self-Defeat

In the first part of Reasons and Persons , Derek Parfit argues that common-sense morality, or M , is self-defeating, so that it must be rejected or revised. I defend M . We can rebut Parfit's argument if we make an assumption about the moral importance of doing what is morally right. We need to assume that this end has sufficient weight in M .     

Complex mediating effects of rumination facets between personality traits and depressive symptoms

This study investigates whether facets of rumination statistically mediate the relationships between Big Five personality traits and depressive symptoms. Self-reported personality traits and rumination were investigated as predictors of depressive symptoms in a cross-sectional sample of 3043 participants aged 18–60 years (68.8% female). Multiple regression analysis investigated which personality traits and rumination facets best explained variance in depressive symptoms. Structural equation modelling was used to determine whether facets of rumination mediated the relationships between personality traits and depressive symptoms. Multiple regression analysis found that variance in depressive symptoms was best explained by the personality traits neuroticism, extroversion, conscientiousness; and both facets of rumination, brooding and reflection. Structural equation modelling added that the effects of neuroticism, extroversion, conscientiousness and openness on depressive symptoms were statistically mediated by brooding; the effects of neuroticism, extroversion and openness to depressive symptoms were statistically mediated by reflection. Rumination facets statistically mediated the effects of various personality traits on depressive symptoms. These results provide insights into which individuals may be best suited to treatments for depression targeting rumination.
