The Effects of Coping, Self-Esteem, and Social Support on Stress and Wellbeing

The present study aimed to add to the literature on the internal and external factors that may buffer the negative effects of stress. Specifically, the present study examined the effects of coping styles, self-esteem, and social support on both psychological wellbeing and stress. Participants (N = 198) were administered a measure of coping styles (COPE), self-esteem (Rosenberg\u27s Self-Esteem Scale), social support (SSQ-R), psychological wellbeing (MHI), and stress (ICSRLE). Results showed problem-focused coping and emotion-focused coping were associated with better psychological wellbeing and lower stress. Avoidant coping was associated with lower psychological wellbeing and higher stress. Self-esteem was also related to higher psychological wellbeing and lower stress. Overall social support network size was predictive of psychological wellbeing in the overall sample, but not predictive of stress; however, in the college age group, overall social support was not predictive of wellbeing or stress. Satisfaction with social support was predictive of both wellbeing and stress. In general, the findings of the present study agreed with the findings of previous research. Exceptions and implications are discussed

Demonstration of reduced radiation losses in hohlraums made from cocktail mixtures by measuring increased radiation temperatures

We present results from experiments, numerical simulations, and analytic modeling that demonstrate enhanced radiation confinement of hohlraums made from cocktail materials. We summarize the results from several previous planar sample experiments that showed the potential promise of cocktails. We then discuss a series of more recent hohlraum experiments that attempted to demonstrate enhanced radiation confinement. Once we understood the importance of oxygen contamination in increasing the specific heat and wall losses of uranium-based cocktails, we implemented new manufacturing and handling techniques for cocktail hohlraums that led to our demonstration of a significant increase in radiation temperature (up to +7eV at 300 eV) compared to a pure Au hohlraum. This data agrees well with modeling and suggests we can expect an 18% reduction in wall loss (and 10% reduction in laser energy) for the current ignition design by switching to cocktail hohlraums
