Effective Online Course Delivery in Correctional Settings: A Pilot

This paper provides an analysis of best practices for the design and delivery of online programming within correctional facilities, ascertained from the evaluation of a pilot course. Utilizing the case study methodology, it was observed that fully online coursework may be delivered within controlled settings. Key considerations for effective design and delivery centered around scheduling regular check-ins with administration from the University and the Correctional Center, conducting technology testing on a set cadence, incorporating synchronous components and evaluating opportunities for the inclusion of courseembedded advising to ensure engagement. Future directions include continued delivery of a Baccalaureate program, the incorporation of micro-credentials to provide targeted training in key areas of relevance and degree continuity planning to support degree completion among recently released individuals

Building an Online Community Through Research

One of the more complex things to do when becoming a new faculty is meeting the scholarship expectations of your role. A finished dissertation does not easily equate to a peer-reviewed publication later. What if we could give students the tools to embrace scholarship before graduating? This paper outlines a process for engaging online learners in research endeavors outside the course room. It also shows how this unique method can increase community and belonging among peers. The model presented here can be used for research and other community-based projects. While it is useful for faculty development, it is designed to benefit both experienced and new faculty. However, the primary purpose of this model is student development. This model is meant to give the students the skills and tools they need to become researchers on their own

Five-day regimen of intramuscular or subcutaneous self-administered adrenocorticotropic hormone gel for acute exacerbations of multiple sclerosis: a prospective, randomized, open-label pilot trial

James P Simsarian, Carol Saunders, D Michelle SmithNeurology Center of Fairfax Ltd, Fairfax, VA, USABackground: Despite over 50 years of experience with adrenocorticotropic hormone (ACTH) as a treatment for acute exacerbations of multiple sclerosis, there have been no trials examining the options of the 2–3-week dosing regimen or intramuscular injection protocol used in the original trials. At our clinic, we performed a small, prospective, randomized pilot study to examine the efficacy and safety of, and patient satisfaction with, a short (five-day) self-administered ACTH dosing protocol for exacerbations of multiple sclerosis, and to compare the subcutaneous and intramuscular routes of administration.Methods: Patients for this study were recruited from an outpatient treatment clinic. Each patient self-administered natural ACTH gel 80 U/day by subcutaneous or intramuscular injection for five consecutive days and was evaluated at baseline and on days 7 and 14. Patient feedback was collected using the Patient Global Impression of Change (PGI-C, the primary efficacy measure), a patient global visual analog scale, the Expanded Disability Status Scale, a timed walk, the Nine-hole Peg Test, and the Clinical Global Impression of Change.Results: Of the 20 enrolled patients (mean age 39.5 years), 19 completed the study. On day 14, 61.1% of patients (11 of 18 with day 14 scores) were treatment responders, and rated their condition as "very much improved" or "much improved" on the PGI-C. The intramuscular group had numerically more responders, but there was no significant difference in the proportion of responders between the intramuscular and subcutaneous groups at day 14 (P = 0.3). The intramuscular route of injection was associated with more injection site pain than the subcutaneous route.Conclusion: A shorter five-day course of intramuscular or subcutaneous ACTH gel may improve symptoms associated with acute exacerbations of multiple sclerosis. Larger studies with standard of care controls are needed to confirm whether this shorter course of intramuscular or subcutaneous ACTH gel is effective and could potentially be substituted for the standard 14-day treatment.Keywords: adrenocorticotropic hormone, ACTH, multiple sclerosis, acute exacerbations, Acthar® Gel, autoimmune disease

Association of Osteoarthritis with Perfluorooctanoate and Perfluorooctane Sulfonate in NHANES 2003–2008

Background: Perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) are persistent, synthetic industrial chemicals. Perfluorinated compounds are linked to health impacts that may be relevant to osteoarthritis, cartilage repair, and inflammatory responses. Objectives: We investigated whether PFOA and PFOS exposures are associated with prevalence of osteoarthritis, and whether associations differ between men and women. Methods: We used multiple logistic regression to estimate associations between serum PFOA and PFOS concentrations and self-reported diagnosis of osteoarthritis in persons 20–84 years of age who participated in NHANES during 2003–2008. We adjusted for potential confounders including age, income, and race/ethnicity. Effects by sex were estimated using stratified models and interaction terms. Results: Those in the highest exposure quartile had higher odds of osteoarthritis compared with those in the lowest quartile [odds ratio (OR) for PFOA = 1.55; 95% CI: 0.99, 2.43; OR for PFOS = 1.77; 95% CI: 1.05, 2.96]. When stratifying by sex, we found positive associations for women, but not men. Women in the highest quartiles of PFOA and PFOS exposure had higher odds of osteoarthritis compared with those in the lowest quartiles (OR for PFOA = 1.98; 95% CI: 1.24, 3.19 and OR for PFOS = 1.73; 95% CI: 0.97, 3.10). Conclusions: Higher concentrations of serum PFOA were associated with osteoarthritis in women, but not men. PFOS was also associated with osteoarthritis in women only, though effect estimates for women were not significant. More research is needed to clarify potential differences in susceptibility between women and men with regard to possible effects of these and other endocrine-disrupting chemicals

Automatic Thoughts and Cognitive Restructuring in Cognitive Behavioral Group Therapy for Social Anxiety Disorder

The goal in (Heimberg, R. G. [1991]. A manual for conducting Cognitive Behavior Group Therapy for social phobia (2nd ed.), unpublished manuscript) cognitive behavioral group therapy (CBGT) for social anxiety disorder (social phobia) is to challenge irrational automatic thoughts and create exposures to provide disconfirming evidence for these irrational thoughts as well as habituation to fearful stimuli. Yet little is known about the types of thoughts reported by socially anxious individuals in therapy or which thoughts therapists select for cognitive restructuring in CBGT sessions. The present study analyzed the semantic content of automatic thoughts reported in CBGT and found that the most common thoughts related to poor social performance, negative labels by others, and the anticipation of negative outcomes in feared situations. Principle components analyses indicated the automatic thoughts reflected three underlying themes: Experiencing Anxiety, Negative Self-Evaluation, and Fear of Negative Evaluation. The paper also describes exploratory analyses of which thoughts became the focus of cognitive restructuring exercises and their relationship to treatment outcome. Implications for cognitive therapy are also discussed

Investigating five key predictive text entry with combined distance and keystroke modelling

This paper investigates text entry on mobile devices using only five-keys. Primarily to support text entry on smaller devices than mobile phones, this method can also be used to maximise screen space on mobile phones. Reported combined Fitt's law and keystroke modelling predicts similar performance with bigram prediction using a five-key keypad as is currently achieved on standard mobile phones using unigram prediction. User studies reported here show similar user performance on five-key pads as found elsewhere for novice nine-key pad users

Modeling the Optical-X-ray Accretion Lag in LMC X-3: Insights Into Black-Hole Accretion Physics

The X-ray persistence and characteristically soft spectrum of the black hole X-ray binary LMC X-3 make this source a touchstone for penetrating studies of accretion physics. We analyze a rich, 10-year collection of optical/infrared (OIR) time-series data in conjunction with all available contemporaneous X-ray data collected by the ASM and PCA detectors aboard the Rossi X-ray Timing Explorer. A cross-correlation analysis reveals an X-ray lag of ~2 weeks. Motivated by this result, we develop a model that reproduces the complex OIR light curves of LMC X-3. The model is comprised of three components of emission: stellar light; accretion luminosity from the outer disk inferred from the time-lagged X-ray emission; and light from the X-ray-heated star and outer disk. Using the model, we filter a strong noise component out of the ellipsoidal light curves and derive an improved orbital period for the system. Concerning accretion physics, we find that the local viscous timescale in the disk increases with the local mass accretion rate; this in turn implies that the viscosity parameter alpha decreases with increasing luminosity. Finally, we find that X-ray heating is a strong function of X-ray luminosity below ~50% of the Eddington limit, while above this limit X-ray heating is heavily suppressed. We ascribe this behavior to the strong dependence of the flaring in the disk upon X-ray luminosity, concluding that for luminosities above ~50% of Eddington, the star lies fully in the shadow of the disk.Comment: Accepted in ApJ (12 pages long in emulateapj format

Quantum oscillations in the parent pnictide BaFe2_2As2_2 : itinerant electrons in the reconstructed state

We report quantum oscillation measurements that enable the direct observation of the Fermi surface of the low temperature ground state of \ba122. From these measurements we characterize the low energy excitations, revealing that the Fermi surface is reconstructed in the antiferromagnetic state, but leaving itinerant electrons in its wake. The present measurements are consistent with a conventional band folding picture of the antiferromagnetic ground state, placing important limits on the topology and size of the Fermi surface.Comment: 5 pages, 3 figure

Virtual Dissertation Circles: Student Engagement Strategies and Lessons Learned

A great body of research demonstrates that online doctoral student needs center around motivation, community, affirmation from peers, and feedback (e.g., Akojie, Entrekin, Bacon, & Kanai, 2019; Gibson, Fields, Wladkowski, Kusmaul, Greenfield, & Mauldin, 2019; Kumar, & Coe, 2017).This study focused on the development of a Dissertation Circles Model to provide students with a forum for connecting with peers at various stages of the dissertation process with rotated supervision by long-serving dissertation chairs within the department. Future directions include expansion of the initiative to include non-clinical practicum, to support improved preparation of students by setting expectations and providing mentorship opportunities
