A Manualized Occupational Therapy Communication Skills Module for Clients with PTSD
Individuals with post-traumatic stress disorder (PTSD) experience a variety of barriers and challenges that impact their daily occupational performance, engagement, well-being, and quality of life. There is a lack of research in the area of manualized occupational therapy (OT) treatment options for people with PTSD. Literature has expressed a need for the development of a manual-based OT treatment program for people with PTSD with communication skills training as an intervention component. The purpose of this project is to create a manualized OT communication skills intervention module for occupational therapists to implement with clients with PTSD for improved occupational performance and quality of life. This project consisted of a intervention module with five sections, one section specifically designed as a module introduction for occupational therapy practitioners, and four intervention sessions related to topics on communication skills.https://soar.usa.edu/otdcapstonesspring2024/1056/thumbnail.jp
Intimate partner femicide in context: An examination of firearm type across the rural/urban divide
Previous research on intimate partner homicide (IPH) has established that intimate partner homicides are overwhelmingly committed with a firearm. Emerging research suggests the risk of partner violence turning lethal in rural America is often exacerbated by a higher prevalence of firearm ownership, as well as the limited availability of victim support services, economic disadvantages, and access to healthcare services. Given that IPH represents one of the most common types of homicide in rural areas, understanding the prevalence and associated risk and protective factors presents important policy implications. Using county-level data from the Center for Disease Control and Prevention's National Violent Death Reporting System for the years 2015-2016 and controlling for well-established structural correlates of IPH, this research examines the nature and prevalence of IPH across county context. We investigate whether leading predictors of IPH (firearm access, domestic violence support services, and economic disadvantage) are associated with firearm and non-firearm IPH incidents equally and whether these relationships hold when comparing rural and urban counties. We further examine the unique dynamics of firearm specific IPH, including a comparison of IPH incidents committed with handguns versus long guns, given their differing prevalence and cultural context in rural and urban communities. Findings reveal important differences across the rural-urban divide and weapon types. Implications for research and policy are discussed
An assessment of unstructured grid technology for timely CFD analysis
An assessment of two unstructured methods is presented in this paper. A tetrahedral unstructured method USM3D, developed at NASA Langley Research Center is compared to a Cartesian unstructured method, SPLITFLOW, developed at Lockheed Fort Worth Company. USM3D is an upwind finite volume solver that accepts grids generated primarily from the Vgrid grid generator. SPLITFLOW combines an unstructured grid generator with an implicit flow solver in one package. Both methods are exercised on three test cases, a wing, and a wing body, and a fully expanded nozzle. The results for the first two runs are included here and compared to the structured grid method TEAM and to available test data. On each test case, the set up procedure are described, including any difficulties that were encountered. Detailed descriptions of the solvers are not included in this paper

Longitudinal associations between perceived stress and anhedonia during psychotherapy
Background: Chronic stress alters reward sensitivity and contributes to the emergence of anhedonia. In clinical samples, the perception of stress is a strong predictor of anhedonia. While there is substantial evidence demonstrating psychotherapy reduces perceived stress, little is known regarding the effects of treatment-related decreases in perceived stress on anhedonia. Methods: The current study investigated reciprocal relations between perceived stress and anhedonia using a cross-lagged panel model approach in a 15-week clinical trial examining the effects of Behavioral Activation Treatment for Anhedonia (BATA), a novel psychotherapy to treat anhedonia, compared to a Mindfulness-Based Cognitive Therapy (MBCT) comparison intervention (ClinicalTrials.gov Identifiers NCT02874534 and NCT04036136). Results: Treatment completers (n = 72) experienced significant reductions in anhedonia (M = −8.94, SD = 5.66) on the Snaith-Hamilton Pleasure Scale (t(71) = 13.39, p < .0001), and significant reductions in perceived stress (M = −3.71, SD = 3.88) on the Perceived Stress Scale (t(71) = 8.11, p < .0001) following treatment. Across all treatment-seeking participants (n = 87), a longitudinal autoregressive cross-lagged model revealed significant paths showing that higher levels of perceived stress at treatment Week 1 predicted reductions in anhedonia at treatment Week 4; lower levels of perceived stress at Week 8 predicted reductions in anhedonia at Week 12. Anhedonia did not significantly predict perceived stress at any stage of treatment. Conclusions: This study showed specific timing and directional effects of perceived stress on anhedonia during psychotherapy treatment. Individuals with relatively high perceived stress at the start of treatment were more likely to report relatively lower anhedonia a few weeks into treatment. At mid-treatment, individuals with low perceived stress were more likely to report lower anhedonia towards the end of treatment. These results demonstrate that early treatment components reduce perceived stress, thus allowing for downstream changes in hedonic functioning during mid-late treatment. The findings presented here suggest it will be critically important for future clinical trials evaluating novel interventions for anhedonia to measure stress levels repeatedly, as an important mechanism of change.

Estimated Environmental Exposures for MISSE-3 and MISSE-4
Describes the estimated environmental exposure for MISSE-2 and MISSE-4. These test beds, attached to the outside of the International Space Station, were planned for 3 years of exposure. This was changed to 1 year after MISSE-1 and -2 were in space for 4 years. MISSE-3 and -4 operate in a low Earth orbit space environment, which exposes them to a variety of assaults including atomic oxygen, ultraviolet radiation, particulate radiation, thermal cycling, and meteoroid/space debris impact, as well as contamination associated with proximity to an active space station. Measurements and determinations of atomic oxygen fluences, solar UV exposure levels, molecular contamination levels, and particulate radiation are included
CU Comae: a new field double-mode RR Lyrae, the most metal poor discovered to date
We report the discovery of a new double-mode RR Lyrae variable (RRd) in the
field of our Galaxy: CU Comae. CU Comae is the sixth such RRd identified to
date and is the most metal-poor RRd ever detected. Based on BVI CCD photometry
spanning eleven years of observations, we find that CU Comae has periods
P0=0.5441641 +/-0.0000049d and P1=0.4057605 +/-0.0000018d. The amplitude of the
primary (first-overtone) period of CU Comae is about twice the amplitude of the
secondary (fundamental) period. The combination of the fundamental period of
pulsation P0 and the period ratio of P1/P0=0.7457 places the variable on the
metal-poor side of the Petersen diagram, in the region occupied by M68 and M15
RRd's. A mass of 0.83 solar masses is estimated for CU Comae using an updated
theoretical calibration of the Petersen diagram. High resolution spectroscopy
(R=30,000) covering the full pulsation cycle of CU Comae was obtained with the
2.7 m telescope of the Mc Donald Observatory, and has been used to build up the
radial velocity curve of the variable. Abundance analysis done on the four
spectra taken near minimum light (phase: 0.54 -- 0.71) confirms the metal poor
nature of CU Comae, for which we derive [Fe/H]=-2.38 +/-0.20. This value places
this new RRd at the extreme metal-poor edge of the metallicity distribution of
the RR Lyrae variables in our Galaxy.Comment: 21 pages including 8 Tables, Latex, 11 Figures. Accepted for
