Differences in the Experience of Caregiving Between Spouse and Adult Child Caregivers in Dementia With Lewy Bodies.
Background and objectivesDementia caregiving has been associated with increased burden, depression, grief, a decreased sense of well-being and quality of life, and a weakening of social support. Little is known about the experience of caregiving in Dementia with Lewy Bodies (DLB). The present study examines differences in the caregiving experience of spouse versus adult child caregivers of individuals with DLB.Research design and methodsIn this cross-sectional analytic study of spouses (n = 255) and adult children (n = 160) caregivers of individuals with DLB, participants completed an online survey of burden, grief, depression, well-being, quality of life, and social support.ResultsAdult child caregivers were more likely to care for women (p < .001) and see the care recipient less often (p < .001) than spouses. Adult child caregivers reported lower quality of life (p < .001) and more caregiver burden (p < .009), but also greater social support (p < .001) than spouses. Between group analyses of caregiver type by disease severity demonstrated that spousal caregivers experience greater grief with advancing disease (p = .005), while adult child caregivers increase social support with advancing disease (p < .001).Discussion and implicationsSpouses and adult children experience DLB caregiving differently. This was explained by the younger age of the adult child caregiver, frequency of contact with the care recipient, and differences in the care recipient's characteristics, frequency of neuropsychiatric symptoms, and disease severity. DLB caregiver support for this population should target psychoeducation for complicated neuropsychiatric symptoms in the care recipient. Screening all DLB caregivers for burden, grief, and depression is suggested to identify those that may benefit most from intervention. Spouses specifically may benefit from interventions that target increasing social support, while adult child caregivers may benefit from interventions aimed at mitigating burden and improving quality of life

Featural density in picture naming among college age and older adults
When naming pictures, speakers are slower to name pictures with multiple appropriate labels (e.g., couch/sofa) compared to pictures consistently given a single label. This increased naming time is generally seen as a reflection of the time needed to resolve competition between the competing labels. Older speakers show a greater influence of name agreement that could reflect a specific age-related increase in sensitivity to lexical competition when speaking. The present study examines speakers’ sensitivity to a more pervasive form of lexical competition. Using normative data in which individuals report features associated with object concepts, it is possible to measure the extent to which concepts share features with other concepts. Pictures matched with concepts with high featural overlap with other concepts should show greater competition during naming than those matched to concepts with lower levels of featural overlap. Initial evidence in younger speakers is consistent with this prediction. Here, we conducted a set of experiments to replicate this result in younger speakers and test the prediction that older speakers will be more sensitive to variations in featural overlap than younger speakers. We observed a marginal negative relationship between featural overlap and response times if participants were not pre-exposed to stimuli. With pre-exposure we saw a significant negative effect of feature overlap and response times in both young and older adults. There was no clear differential effect of featural overlap on semantic competition for young and older adults.M.S

Introduction to NuMAD: A numerical manufacturing and design tool
Given the complex geometry of most wind turbine blades, structural modeling using the finite element method is generally performed using a unique model for each particular blade analysis. Development time (often considerable) spent creating a model for one blade may not aid in the development of a model for a different blade. In an effort to reduce model development time and increase the usability of advanced finite element analysis capabilities, a new software tool, NuMAD, is being developed

Application of Resin Transfer Molding to the Manufacture of Wind Turbine Blade Substructures. Final Report
The U.S. has generally lacked the capability for an iterative process of detailed structural design, manufacturing, and testing at the full blade level to achieve specific structural performance, cost, and weight targets. This project examined the effects that different composites processing methods had on the performance of representative blade substructures. In addition, the results of the testing of these substructures was used to validate NuMAD, the design tool developed at Sandia National Laboratories

The status of the US VAWT program
Vertical axis wind turbine (VAWT) technology in the United States started in the early 1970s directly from the original work in Canada. The close, and very productive relationships among laboratories, universities and industry have continued since that time. This paper briefly discusses the significant technical progress and rather dramatic programmatic changes that have occurred in the past 18 to 24 months on the US side of the border. 20 refs., 14 figs
