Fostering Culture Change In An Undergraduate Business Program: Nudging Students Towards Greater Involvement In Extra-Curricular Activities
A report on a successfully implemented program to increase student participation in extra-curricular activities in an undergraduate business program with a high percentage of first-generation college students. A market-research study offered insight as to why students were not participating before the program was launched. Greater participation in extra-curricular activities was used as a means to provide valuable career preparation and to develop professional habits. Participation was encouraged with very small rewards tied to existing courses, consistent with the nudging mechanism of behavioral economics
Point-light biological motion perception activates human premotor cortex
Motion cues can be surprisingly powerful in defining objects and events. Specifically, a handful of point-lights attached to the joints of a human actor will evoke a vivid percept of action when the body is in motion. The perception of point-light biological motion activates posterior cortical areas of the brain. On the other hand, observation of others' actions is known to also evoke activity in motor and premotor areas in frontal cortex. In the present study, we investigated whether point-light biological motion animations would lead to activity in frontal cortex as well. We performed a human functional magnetic resonance imaging study on a high-field-strength magnet and used a number of methods to increase signal, as well as cortical surface-based analysis methods. Areas that responded selectively to point-light biological motion were found in lateral and inferior temporal cortex and in inferior frontal cortex. The robust responses we observed in frontal areas indicate that these stimuli can also recruit action observation networks, although they are very simplified and characterize actions by motion cues alone. The finding that even point-light animations evoke activity in frontal regions suggests that the motor system of the observer may be recruited to "fill in" these simplified displays
The Trypanosoma cruzi enzyme TcGPXI is a glycosomal peroxidase and can be linked to trypanothione reduction by glutathione or tryparedoxin.
Trypanosoma cruzi glutathione-dependent peroxidase I (TcGPXI) can reduce fatty acid, phospholipid, and short chain organic hydroperoxides utilizing a novel redox cycle in which enzyme activity is linked to the reduction of trypanothione, a parasite-specific thiol, by glutathione. Here we show that TcGPXI activity can also be linked to trypanothione reduction by an alternative pathway involving the thioredoxin-like protein tryparedoxin. The presence of this new pathway was first detected using dialyzed soluble fractions of parasite extract. Tryparedoxin was identified as the intermediate molecule following purification, sequence analysis, antibody studies, and reconstitution of the redox cycle in vitro. The system can be readily saturated by trypanothione, the rate-limiting step being the interaction of trypanothione with the tryparedoxin. Both tryparedoxin and TcGPXI operate by a ping-pong mechanism. Overexpression of TcGPXI in transfected parasites confers increased resistance to exogenous hydroperoxides. TcGPXI contains a carboxyl-terminal tripeptide (ARI) that could act as a targeting signal for the glycosome, a kinetoplastid-specific organelle. Using immunofluorescence, tagged fluorescent proteins, and biochemical fractionation, we have demonstrated that TcGPXI is localized to both the glycosome and the cytosol. The ability of TcGPXI to use alternative electron donors may reflect their availability at the corresponding subcellular sites

Delivery of Family-Based Treatment for Adolescent Anorexia Nervosa in a Public Health Care Setting: Research Versus Non-Research Specialty Care.
Comparing evidence-based psychotherapy (EBP) to usual care typically demonstrates the superiority of EBPs, although this has not been studied for eating disorders EBPs such as family-based treatment (FBT). The current study set out to examine weight outcomes for adolescents with anorexia nervosa who received FBT through a randomized clinical research trial (RCT, n = 54) or non-research specialty care (n = 56) at the same specialist pediatric eating disorder service. Weight was recorded throughout outpatient treatment (up to 18 sessions over 6 months), as well as at 6- and 12-month follow-up. Survival curves were used to examine time to weight restoration [greater than 95% median body mass index (mBMI)] as predicted by type of care (RCT vs. non-research specialty care), baseline clinical and demographic characteristics, and their potential interaction. Results did not indicate a significant main effect for type of care, but there was a significant effect for baseline weight (p = .03), such that weight restoration was achieved faster across both treatment types for those with a higher initial %mBMI. These data suggest that weight restoration achieved in non-research specialty care FBT was largely similar to that achieved in a controlled research trial.

Using electronic health records to support clinical trials: a report on stakeholder engagement for EHR4CR
Background. The conduct of clinical trials is increasingly challenging due to greater complexity and governance requirements as well as difficulties with recruitment and retention. Electronic Health Records for Clinical Research (EHR4CR) aims at improving the conduct of trials by using existing routinely collected data, but little is known about stakeholder views on data availability, information governance, and acceptable working practices. Methods. Senior figures in healthcare organisations across Europe were provided with a description of the project and structured interviews were subsequently conducted to elicit their views. Results. 37 structured interviewees in Germany, UK, Switzerland, and France indicated strong support for the proposed EHR4CR platform. All interviewees reported that using the platform for assessing feasibility would enhance the conduct of clinical trials and the majority also felt it would reduce workloads. Interviewees felt the platform could enhance trial recruitment and adverse event reporting but also felt it could raise either ethical or information governance concerns in their country. Conclusions. There was clear support for EHR4CR and a belief that it could reduce workloads and improve the conduct and quality of trials. However data security, privacy, and information governance issues would need to be carefully managed in the development of the platform
Level I FW in a Simulated Environment: A Blueprint on How to Use Simucase™
Simulation education is a sought-out teaching modality in allied healthcare education to bridge the classroom and the clinic. In addition to developing healthcare student professionals’ skills, attitudes and key competencies, simulation can also be used to address the national fieldwork shortage, as well as site capacity issues related to the current pandemic. Although the Accreditation Council for Occupational Therapy Education (ACOTE) has recently indicated that simulation is an acceptable method to deliver Level I fieldwork, there are limited resources available. This paper will provide a pedagogical blueprint for incorporating computer-based simulation and case-based learning principles using the Simucase™ platform for a one-week, Level I fieldwork experience. A model of best practice for a Level I fieldwork experience will be shared, to include a framework with learning objectives, example syllabus, student assessment, and debriefing rubric. This model aligns with the Occupational Therapy Education Research Agenda, which challenges the profession to expand faculty development, provide resources on instructional methods and identify signature pedagogies in occupational therapy fieldwork education
The Effect of Remote Work on Family and Work Dynamics within the Sport Industry
The purpose of this study was to investigate the effect of required remote work on work–family spillover within U.S. college sport. In particular, we examined the changes in work–family spillover (positive and negative), job commitment, and workaholism as employee’s work environment changed from traditional work expectations to work from home, and if these changes were, at least partially, due to parental responsibilities. Data were collected from full-time, National Collegiate Athletic Association (NCAA) athletic department employees (n = 1,139) in November 2019 and again in May 2020 following the onset of the COVID-19 pandemic and after the transition to remote work. Results showed that sport employees found a number of benefits associated with working remotely, including a significant decrease in negative work–family spillover. However, employees with children at home reported higher levels of negative family–work spillover after going to remote work. Workaholism was also higher after the move to remote work. Both theoretical and practical implications are discussed
Mindfulness in the Occupational Therapy Classroom: Infusing Grit, Gratitude Practice, and a Growth Mindset into OT Education
With the rigor of occupational therapy programs increasing to meet the demands of the diverse healthcare system, students are reporting stress and anxiety at an increasing rate. This mixed methods study assessed the outcomes of occupational therapy students who participated in a comprehensive mindfulness program that included interventions on grit, gratitude practice, and growth mindset. Twenty-four occupational therapy students participated in the 10-week mindful-based intervention program prior to a Level I fieldwork experience. Data was collected pre- and post-intervention using the 12-item Grit Scale, the Gratitude Questionnaire (GQ-6), the Motivated Strategies for Learning Questionnaire (MSLQ), journal entries, and a satisfaction survey at the completion of the program. Student outcomes included statistically significant changes in grit and gratitude. While growth mindset was not statistically significant, there were meaningful changes in reported self-regulation, both in the classroom and clinical experience. Infusing mindful-based curriculum into occupational therapy education can have a positive effect on both the occupational therapy student and subsequent clinical experiences, ultimately carrying over to therapeutic client interactions. Educators within academia and in clinical settings can utilize similar interventions to ensure students are holistically prepared to meet the demands of the current healthcare system
