We present a spectrometer design based on a novel nanofabricated blazed X-ray transmission grating which is modeled to have superior efficiency. Here we outline a full instrument design proposed for Constellation-X which is expected to give resolving powers ~2000 (HEW). The spectrometer advantages include lower mass budget and smaller diffractor area, as(More)
Research with survivors of torture has generated considerable variability in prevalence rates of posttraumatic stress disorder (PTSD). Multiple risk and resilience factors may affect this variability, increasing or decreasing the likelihood of experiencing psychological distress. This study sought to investigate the effect of several such resilience(More)
Although psychosocial programming is seen as essential to the humanitarian response to the Darfur conflict, aid groups lack culturally-appropriate assessment instruments for monitoring and evaluation. The current study used an emic-etic integrated approach to: (i) create a culturally-appropriate measure of distress (Study 1), and (ii) test the measure in(More)
This study examined the validity and utility of PTSD among 320 adults in Afghanistan. Findings support the validity of PTSD in this cultural context: PTSD symptoms were highly prevalent, shared common variance, and correlated as expected with exposure to traumatic stress. However, only limited support was found for the clinical utility of PTSD. Other types(More)
Although a subjective component of trauma is commonly recognized in diagnosing posttraumatic stress disorder (PTSD), there are few studies that specifically address Criterion A2, and none addressing this issue among undocumented immigrants. We assessed 212 arriving undocumented immigrants with diverse trauma histories to investigate concordance between(More)
Despite the central role of posttraumatic stress disorder (PTSD) in international humanitarian aid work, there has been little examination of the measurement invariance of PTSD measures across culturally defined refugee subgroups. This leaves mental health workers in disaster settings with little to support inferences made using the results of standard(More)
