Deborah Richardson interview (2) conducted on May 24, 1985 about the Boonshoft School of Medicine at Wright State University

This is the second in a series of interviews with Ms. Deborah Richardson, third-year medical student in the Wright State University School of Medicine. In this interview, Ms. Richardson continues her discussion of her education as an undergraduate medical student at Wright State University. She concentrates in the first part of the interview on her experiences as a first-year student. She explores the ramifications and responsibilities of being a medical student, with its effect on her studies and home life. After discussing her first-year classes, schedule, and student life, Ms. Richardson goes on to describe the end of her first year and her summer activities. In the second part of the interview, Ms. Richardson examines her second year of medical school, with a focus on the problems of the female medical student. She discusses the differences between her first and second years, and her anxieties over the upcoming National Boards Examination

Deduction of a Functional Dependency from a Set of Functional Dependencies

This paper describes an algorithm called the Deduction Tracing Algorithm (DTA) which utilizes basic properties of functional dependencies from database systems and a modification of a tree search algorithm from artificial intelligence. The algorithm takes a set of functional dependencies, F, along with a specific functional dependency L → R as input and produces a list of functional dependencies from F that can be used to deduce L → R. The resulting algorithm is easily automated to provide relational database users with a tool for organizing their queries

The influence of depression-PTSD comorbidity on health-related quality of life in treatment-seeking veterans

Objective: Posttraumatic stress disorder (PTSD) and depression substantially impair healthrelated quality of life (HRQOL) for many Canadian Armed Forces (CAF) veterans. Although PTSD and depression are highly comorbid, little is known about whether the disorders may interact in their association with HRQOL. We sought to investigate whether depressive symptoms modify the relation between PTSD and HRQOL in treatment-seeking veterans. Method: We accessed the clinical data of 545 CAF veterans aged 18 to 65 years who were seeking treatment at a specialized clinic in London, Ontario. We used hierarchical linear regression to assess the additive and multiplicative relations between depression and PTSD symptoms on HRQOL, controlling for age and alcohol/substance abuse. Simple slopes were examined to probe significant interactions. Results: Probable PTSD and major depression were present in 77.4% and 85.3% of the sample, respectively, and 73.0% of the sample presented with probable PTSD-depression comorbidity. Depression symptoms significantly modified the relation between PTSD symptoms and overall mental HRQOL (β = 0.12,

Solar Energetic Particle-Associated Coronal Mass Ejections Observed by the Mauna Loa Solar Observatory Mk3 and Mk4 Coronameters

We report on the first comprehensive study of the coronal mass ejections (CMEs) associated with $\sim$25 MeV solar energetic proton (SEP) events in 1980-2013 observed in the low/inner corona by the Mauna Loa Solar Observatory (MLSO) Mk3 and Mk4 coronameters. Where possible, these observations are combined with spacebased observations from the Solar Maximum Mission C/P, P78-1 SOLWIND or SOHO/LASCO coronagraphs. The aim of the study is to understand directly-measured (rather than inferred from proxies) CME motions in the low to middle corona and their association with SEP acceleration, and hence attempt to identify early signatures that are characteristic of SEP acceleration in ground-based CME observations that may be used to warn of impending SEP events. Although we find that SEP events are associated with CMEs that are on average faster and wider than typical CMEs observed by MLSO, a major challenge turns out to be determining reliable estimates of the CME dynamics in the low corona from the 3-minute cadence Mk3/4 observations since different analysis techniques can produce inconsistent results. This complicates the assessment of what early information on a possible SEP event is available from these low coronal observationsComment: To be published in Solar Physic

The CHARA Array resolves the long-period Wolf-Rayet binaries WR 137 and WR 138

We report on interferometric observations with the CHARA Array of two classical Wolf-Rayet stars in suspected binary systems, namely WR 137 and WR 138. In both cases, we resolve the component stars to be separated by a few milliarcseconds. The data were collected in the H-band, and provide a measure of the fractional flux for both stars in each system. We find that the WR star is the dominant H-band light source in both systems ($f_{\rm WR, 137} = 0.59\pm0.04$; $f_{\rm WR, 138} = 0.67\pm0.01$), which is confirmed through both comparisons with estimated fundamental parameters for WR stars and O dwarfs, as well as through spectral modeling of each system. Our spectral modeling also provides fundamental parameters for the stars and winds in these systems. The results on WR 138 provide evidence that it is a binary system which may have gone through a previous mass-transfer episode to create the WR star. The separation and position of the stars in the WR 137 system together with previous results from the IOTA interferometer provides evidence that the binary is seen nearly edge-on. The possible edge-on orbit of WR 137 aligns well with the dust production site imaged by the Hubble Space Telescope during a previous periastron passage, showing that the dust production may be concentrated in the orbital plane.Comment: 11 pages, 4 tables, 7 figures, accepted to MNRA

Examining the Association between Psychiatric Illness and Suicidal Ideation in a Sample of Treatment-Seeking Canadian Peacekeeping and Combat Veterans with Posttraumatic Stress Disorder

Objective: Our study examines the association between suicidal ideation and and self-reported symptoms of posttraumatic stress disorder (PTSD), major depressive disorder (MDD), generalized anxiety disorder (GAD), and alcohol use disorder (AUD) in a sample of treatment-seeking Canadian combat and peacekeeping veterans; and identifies potential predictors of suicidal ideation. Methods: Actively serving Canadian Forces and Royal Canadian Mounted Police members and veterans seeking treatment at the Parkwood Hospital Operational Stress Injury Clinic (n = 250) completed measures including the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire, the Alcohol Use Disorder Identification Test, and the PTSD Checklist—Military Version (PCL-M) between January 2002 and December 2010. Regression analyses were used to determine the respective impact of PTSD, and self-reported symptoms of MDD, GAD, AUD, and anxiety on suicidal ideation. Results: Most people met PCL-M screening criteria for PTSD (73.6%, n = 184), while 70.8% (n = 177) screened positively for a probable major depressive episode. PTSD symptom was significantly associated with suicidal ideation (β = 0.412, P \u3c 0.001). After controlling for self-reported depressive symptom severity, AUD severity, and generalized anxiety, PTSD severity was no longer significantly associated with suicidal ideation (β = 0.043, P = 0.58). Conclusions: Although PTSD alone is associated with suicidal ideation, after controlling for common comorbid psychiatric illnesses, self-reported depressive symptom severity emerged as the most significant predictor of suicidal ideation. These findings support the importance of screening for comorbidities, particularly an MDD, as potentially modifiable conditions that are strongly related to suicidal ideation in military personnel\u27s endorsing criteria for PTSD

A rapid review of the barriers and facilitators of mental health service access among Veterans and their families

Introduction: Transitioning to civilian life after military service can be challenging for both Veterans and their families. Accessible mental health services are crucial during this period to provide support. The objective of this review was to conduct a rapid review to capture the barriers and identify facilitators that influence access to mental health services for Veterans and their families during the post-service transition period. Methods: This review was conducted using the Cochrane Handbook for Systematic Reviews of Interventions as a methodological framework and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses - Rapid Review (PRISMA-RR). Results: A total of 60 articles and 67 independent samples were included in the final data analyses. Across the included articles, this review identified 23 barriers and 14 facilitator themes. Issues navigating the mental health care system was identified as the main challenge among Veterans and their families, and those who received support navigating the system identified this as a significant facilitator. Applying the Theoretical Domains Framework, most of the identified barriers and facilitators were categorized into environmental context and resources domain. Discussion: The heterogeneity in Veterans\u27 and Veteran families\u27 experiences with mental health care-seeking may suggest that access to mental health care for Veterans and Veteran families cannot be solved by addressing one type of barrier alone. Instead, coordinated efforts to address prioritized systemic, logistical, social, and inter-/intrapersonal obstacles are essential for improving access and optimizing mental health care outcomes. These insights underscore the complexity of considerations for Veterans and families accessing mental health care

Short-latency afferent inhibition during selective finger movement

During individual finger movement, two opposite phenomena occur at the level of the central nervous system that could affect other intrinsic hand muscle representations, unintentional co-activation, and surround inhibition (SI). At rest, excitability in the motor cortex (M1) is inhibited at about 20 ms after electric stimulation of a peripheral nerve [short-latency afferent inhibition (SAI)]. We sought to determine whether SAI changes during selective index finger movement. Effects were measured by the response to transcranial magnetic stimulation in two functionally distinct target muscles of the hand [abductor digiti minimi muscle (ADM), first dorsal interosseus muscle (FDI)]. An increase in SAI in the ADM during index finger movement compared to at rest could help explain the genesis of SI. Electrical stimulation was applied to either the little finger (homotopic for ADM, heterotopic for FDI) or the index finger (heterotopic for ADM, homotopic for FDI). During index finger movement, homotopic SAI was present only in the ADM, and the effect of peripheral stimulation was greater when there was less co-activation. Heterotopic SAI found at rest disappeared with movement. We conclude that during movement, homotopic SAI on the muscle in the surround of the intended movement may contribute to SI

Feeling safe at work:Development and validation of the Psychological Safety Inventory

Psychological safety, defined as perceptions that an individual within a team is supported and feels safe to take interpersonal risks, voice opinions, and share ideas, is vital for organizational effectiveness. However, there is no consensus on how workplace psychological safety should be measured. We developed the Psychological Safety Inventory (PSI) in response to organizational needs to accurately assess psychological safety. A 70-item version of the PSI was administered to 497 employees from Canada, the United States, and the United Kingdom. Based on factor analytic findings, we reduced the preliminary PSI to a 30-item, five-factor scale. The PSI showed high reliability and correlated as anticipated with convergent measures. Overall, the PSI is a valid and reliable measure of workplace psychological safety.</p
