Relations between PTSD symptoms and pain interference among older adults

Both the older adult population and the frequency of natural disasters (e.g., hurricanes) increase in the U.S. each year. Consequently, understanding the health experiences that affect older adults specifically following a natural disaster is important for providing effective healthcare and promoting health expectancy. For example, the extent to which PTSD symptoms following a natural disaster contribute to pain severity (beyond the contributions of other psychosocial experiences such as depression) among older adults is not yet clear, and whether this contribution differs by gender or age has yet to be established. The aims of this study were (1) to determine whether symptoms of PTSD after a natural disaster uniquely contribute to pain interference in daily activities, and (2) to examine the potential moderating effects of gender and age on this relation. Secondary analyses were conducted using an existing longitudinal dataset from the Ongoing Research on Aging in New Jersey: Bettering Opportunities for Wellness in Life (ORANJ BOWL) project (N =1,809, MAge = 67.7 years, 68% women). Results showed that PTSD symptoms are a unique contributor to pain interference and that avoidance symptoms accounted for the greatest amount of variance among the PTSD symptoms subscales. However, neither age nor gender moderated the relation between PTSD (and avoidance) symptoms and pain interference. These results may assist public health officials with response planning to natural disasters, as resources and treatments can be provided to address the relation between PTSD and pain interference in the increasing population of older adults

Comparing attitudes toward time and toward money in experienced-based decisions

This paper reports an experimental comparison of attitudes toward time and toward money in experience-based decisions. Preferences were elicited under rank-dependent utility for prospects with two or three consequences expressed either in time or in monetary units. Probabilities were unknown but learned through sampling. More specifically, time and money were compared under two conditions. In a first experiment, both consequences and probabilities of prospects were unknown and learned through sequential sampling. In a second experiment, the possible consequences were revealed after the sampling. A real incentive system was implemented for both time and money. The heterogeneity of preferences was assessed for time and for money through individual and mixed modeling estimations. We observe that the nature of consequences (time or money) modifies probability weighting in terms of elevation and sensitivity. Subjects exhibit more optimism and less sensitivity to probability changes when deciding about time than about money. Revealing the consequences impacts the shape of the utility function and leaves probability weighting unchanged. We also observe that the real incentives have no effect except for the reduction in decision errors. This effect is stronger for money than for time

First-principles GW calculations for DNA and RNA nucleobases

On the basis of first-principles GW calculations, we study the quasiparticle properties of the guanine, adenine, cytosine, thymine, and uracil DNA and RNA nucleobases. Beyond standard G0W0 calculations, starting from Kohn-Sham eigenstates obtained with (semi)local functionals, a simple self-consistency on the eigenvalues allows to obtain vertical ionization energies and electron affinities within an average 0.11 eV and 0.18 eV error respectively as compared to state-of-the-art coupled-cluster and multi-configurational perturbative quantum chemistry approaches. Further, GW calculations predict the correct \pi -character of the highest occupied state, thanks to several level crossings between density functional and GW calculations. Our study is based on a recent gaussian-basis implementation of GW with explicit treatment of dynamical screening through contour deformation techniques.Comment: 5 pages, 3 figure

Making the Most of Interim Assessment Data: Lessons from Philadelphia

Under No Child Left Behind, urban school districts have increasingly turned to interim assessments, administered at regular intervals, to help gauge student progress in advance of annual state exams. These assessments have spawned growing debate among educators, assessment experts, and the testing industry: are they worth the significant investment of money and time? In Making the Most of Interim Assessment Data: Lessons from Philadelphia, Research for Action (RFA) weighs in on this issue. The School District of Philadelphia (SDP) was an early adopter of interim assessments, implementing the exams in 2003. Unlike teachers in some other regions, Philadelphia elementary and middle grades teachers rated these 'Benchmark' assessments highly. However, the study found that enthusiasm did not necessarily correlate with higher rates of student achievement. What did predict student success were three factors -- instructional leadership, collective responsibility, and use of the SDP's Core Curriculum. The report underscores the value of investment in ongoing data interpretation that emphasizes teachers' learning within formal instructional communities, such as grade groups of teachers. This research was funded by the Spencer Foundation and the William Penn Foundation

Racial bias in face perception is sensitive to instructions but not introspection

Faces with typically African features are perceived as darker than they really are. We investigated how early in processing the bias emerges, whether participants are aware of it, and whether it can be altered by explicit instructions. We presented pairs of faces sequentially, manipulated the luminance and morphological features of each, and asked participants which was lighter, and how confident they were in their responses. In Experiment 1, pre-response mouse cursor trajectories showed that morphology affected motor output just as early as luminance did. Furthermore, participants were not slower to respond or less confident when morphological cues drove them to give a response that conflicted with the actual luminance of the faces. However, Experiment 2 showed that participants could be instructed to reduce their reliance on morphology, even at early stages of processing.
