Who is NIL Leaving Out?: Challenges and Solutions for International Student-Athletes
The National Collegiate Athletic Association (NCAA) adopted name, image and likeness (NIL) legislation in July 2021. The expectation was for all NCAA student-athletes to have the opportunity to seek compensation for their NIL, but the reality is quite different. International student-athletes are not easily able to benefit from their NIL due to restrictions placed on off-campus work under the terms of their entrance visas to the United States. This paper explores the need for the NCAA, NCAA member institutions, and government agencies to re-evaluate policies in an effort to ensure all student-athletes have the right to profit off their NIL. It is crucial that the membership is aware of how international student-athletes are confined by student visa regulations. In order to create a fair and equitable experience for all student-athletes, the NCAA and athletic departments need to understand off-campus work regulations and exceptions for international student visas (F-1 visa). Additionally, there is a need to advocate for this specific sub-population of student-athletes. We explore the idea of creating the opportunity for NIL to be on considered on-campus work for international student-athletes, or perhaps even assisting this population in filing exceptions within the constructs of the law. With domestic student-athletes already benefiting from NIL, it is time to find ways to allow international student-athletes to do the same. In essence, such opportunities would create one less barrier for international student-athletes who already face difficulty adjusting to life in the US
A Team Observed Structured Clinical Encounter (TOSCE) for Pre-Licensure Learners in Maternity Care: A Short Report on the Development of an Assessment Tool for Collaboration
Background: Despite the support for Interprofessional Education (IPE) among policymakers, educators and professional regulating bodies, the research literature is limited with respect to the evaluation of effective assessment strategies. This short report outlines the development of a Team Observed Structured Clinical Encounter (TOSCE), which brings together learners from three health professions involved in primary care obstetrics-family physicians, midwives, and obstetricians-as a strategy for assessing collaborative competencies.Methods: An interprofessional research team was brought together to develop and implement the TOSCE. The process by which the team generated TOSCE scenario stations is outlined, including the consensus-building process, based on a modified Delphi technique, to include expert input from others in the field of practice.Findings: The scenarios developed by the research team for the TOSCE are highlighted including the assessment criteria, based on the Canadian InterprofessionalHealth Collaborative's National Competency Framework.Conclusions: The TOSCE is an emerging and innovative learning tool that encourages the development of essential collaborative competencies. The process of developing a TOSCE outlined in this report offers an affordable, streamlined approach that could be used by educators in many disciplines as a summative or formative assessment strategy
Preliminary needs assessment of mobile technology use for healthcare among homeless veterans
Background. Homeless veterans have complex healthcare needs, but experience many barriers to treatment engagement. While information technologies (IT), especially mobile phones, are used to engage patients in care, little is known about homeless veterans\u27 IT use. This study examines homeless veterans\u27 access to and use of IT, attitudes toward health-related IT use, and barriers to IT in the context of homelessness.
Methods. Qualitative interviews were conducted with 30 homeless veterans in different housing programs in Boston, MA, ranging from emergency shelters to supportive transitional housing that allow stays of up to 2 years. Interviews were conducted in person, audio recorded and then transcribed. Three researchers coded transcripts. Inductive thematic analysis was used.
Results. Most participants (90%) had a mobile phone and were receptive to IT use for health-related communications. A common difficulty communicating with providers was the lack of a stable mailing address. Some participants were using mobile phones to stay in touch with providers. Participants felt mobile-phone calls or text messages could be used to remind patients of appointments, prescription refills, medication taking, and returning for laboratory results. Mobile phone text messaging was seen as convenient, and helped participants stay organized because necessary information was saved in text messages. Some reported concerns about the costs associated with mobile phone use (calls and texting), the potential to be annoyed by too many text messages, and not knowing how to use text messaging.
Conclusion. Homeless veterans use IT and welcome its use for health-related purposes. Technology-assisted outreach among this population may lead to improved engagement in care
Implementation of the LANS-alpha turbulence model in a primitive equation ocean model
This paper presents the first numerical implementation and tests of the
Lagrangian-averaged Navier-Stokes-alpha (LANS-alpha) turbulence model in a
primitive equation ocean model. The ocean model in which we work is the Los
Alamos Parallel Ocean Program (POP); we refer to POP and our implementation of
LANS-alpha as POP-alpha. Two versions of POP-alpha are presented: the full
POP-alpha algorithm is derived from the LANS-alpha primitive equations, but
requires a nested iteration that makes it too slow for practical simulations; a
reduced POP-alpha algorithm is proposed, which lacks the nested iteration and
is two to three times faster than the full algorithm. The reduced algorithm
does not follow from a formal derivation of the LANS-alpha model equations.
Despite this, simulations of the reduced algorithm are nearly identical to the
full algorithm, as judged by globally averaged temperature and kinetic energy,
and snapshots of temperature and velocity fields. Both POP-alpha algorithms can
run stably with longer timesteps than standard POP.
Comparison of implementations of full and reduced POP-alpha algorithms are
made within an idealized test problem that captures some aspects of the
Antarctic Circumpolar Current, a problem in which baroclinic instability is
prominent. Both POP-alpha algorithms produce statistics that resemble
higher-resolution simulations of standard POP.
A linear stability analysis shows that both the full and reduced POP-alpha
algorithms benefit from the way the LANS-alpha equations take into account the
effects of the small scales on the large. Both algorithms (1) are stable; (2)
make the Rossby Radius effectively larger; and (3) slow down Rossby and gravity
waves.Comment: Submitted to J. Computational Physics March 21, 200
Challenges of stroke management in resource-limited settings: A case- based reflection
A 19-year-old man presented with a 1-year history of headache, generalised body weakness, progressive memory loss, and disorientation. One month prior to admission, there was aggravation of the weakness of the right upper limb, with new-onset difficulty with mastication, speech impairment, apathy, and urinary incontinence. On clinical examination, the patient had a motor aphasia and a right-sided hemiparesis with increased muscle tone and hyperreflexia. A noncontrast computed tomography (CT) scan of the brain revealed large ischaemic strokes extending beyond the classical vascular territories. Cerebrospinal fluid analysis showed a mildly increased protein level. The electrocardiogram revealed an irregular sinus bradycardia. The remainder of the cardiovascular and laboratory workup was unremarkable. Considering a working diagnosis of central nervous system vasculitis, the patient was treated with aspirin, prednisolone, and physiotherapy. However, he died suddenly a few weeks later. Based on this case, we discuss the challenges of stroke management in resource-limited settings, provide practical tips for general practitioners, reflect on the potential avenues for short- and long-term action, and introduce the budding collaboration platform between the University College London, the University of Liverpool, the Queen Elizabeth Central Hospital, and the Malawi-Liverpool-Wellcome Trust Clinical Research Programme
Prenatal DDT Exposure in Relation to Anthropometric and Pubertal Measures in Adolescent Males
DDT (dichlorodiphenyltrichloroethane), a pesticide once used widely in agriculture and now limited to public health use, remains a controversial chemical because of a combination of benefits and risks. DDT or its breakdown products are ubiquitous in the environment and in humans. Compounds in the DDT family have endocrine actions and have been associated with reproductive toxicity. A previous study reported associations between prenatal exposure to p,p′-DDE [1,1-dichloro-2,2-bis(p-chlorophenyl)-ethylene] and increased height and weight in adolescent boys. We examined a group with higher exposures to see whether similar associations would occur. Our study group was 304 males born in Philadelphia in the early 1960s who had participated in a previous study. Anthropometric and pubertal measures from one to six visits during their adolescent years were available, as were stored maternal serum samples from pregnancy. We measured p,p′-DDE, p,p′-DDT [1,1,1-trichloro-2,2-bis(p-chlorophenyl)-ethane], and o,p′-DDT [1,1,1-trichloro-2-(o-chlorophenyl)-2-(p-chlorophenyl)-ethane] in the maternal serum. Outcomes examined in the boys were height, ratio of sitting height to height, body mass index, triceps skinfold thickness, ratio of subscapular to the sum of triceps and subscapular skinfold thicknesses, skeletal age, serum testosterone, and serum dehydroepiandrosterone sulfate. No associations between prenatal exposure to any of the DDT compounds and any outcome measure were seen
