- ItemCold Water Facial Immersion to Reduce Orthostatic Intolerance(Florida Southern College, 2021-03-29) Rodriguez, Rebecca; Marshall, Erica M.During standing, passive effects of gravity result in venous pooling in the lower extremities. In healthy individuals, these effects are largely offset by actions of the baroreflex and subsequent sympathetic induced vasoconstriction. However, in those who experience orthostatic intolerance (OI), this response may be attenuated and lead to reductions in blood pressure (BP) and presyncope. Interestingly, highly trained aerobic athletes may be at risk of developing OI due to training induced reductions in sensitivity of the baroreflex. Interventions are necessary to mitigate symptoms of OI, but not interfere with exercise training in this population. In the literature, cold-water facial immersion is one intervention that may combat this paradox. Specifically, facial immersion in 0°C cold water, or an ice pack applied to the forehead and cheeks has been shown to increase vasoconstriction in the lower extremities, thus preventing large reductions in BP and symptoms of OI. Collectively, exercise professionals may use cold water facial immersion or ice pack application as part of the exercise prescription for highly trained aerobic individuals who experienced OI.
- ItemUsing the Head Up Tilt Test to Diagnose Orthostatic Intolerance(Florida Southern College, 2021-04-29) Rincon Garcia, Daniela; Marshall, Erica M.Approximately 500,000 individuals have orthostatic intolerance (OI). OI is defined as a reduction in systolic blood pressure (SBP), or diastolic blood pressure (DBP) by at least 20 and 10 mmHg, respectively within three minutes of standing. During standing, reductions in vasoconstriction contribute to venous pooling and then fainting. OI is a primary symptom in postural orthostatic tachycardia syndrome (POTS). In addition to OI, persons with POTS have reduced exercise capacity. POTS can be diagnosed using various autonomic tests, such as the head up tilt (HUT). The HUT is comprised of a 15-30 min rest in the supine position on a tilt table, followed by tilt to 60 degrees for 30-45 min. During this time, HR, SBP, DBP, and electrocardiogram measures are assessed. Collectively, diagnosis is crucial in order to improve symptoms, exercise tolerance and quality of life. Following diagnosis, appropriate interventions can be made. According to the literature, one of the most effective interventions for improving POTS is a progressive exercise program, which has been reported to be superior to use of pharmacologic agents. In summary, this presentation seeks to address OI in POTS patients, explore a modality for its’ diagnoses, and report exercise interventions to improve POTS.
- ItemTraveling Salesman Heuristics(Florida Southern College, 2021-04-29) Horton, Shea; Marshall, John; Lewis, John JackThe traveling salesman problem (TSP) involves trying to find the optimal path to tour a collection of cities, or vertices of a graph, based on their weights. This would seem simple enough with just a few cities, but when a tour needs to be calculated for hundreds or thousands of cities, the run time becomes completely unmanageable. It is for this reason that there are not any perfectly accurate algorithms to find the optimal path in sufficient polynomial time, but rather heuristics that can find near-optimal paths and weights. Our research revolved around finding the differences between the top heuristics for this problem and determining which would be the best for us to implement. We ended up picking Christofide’s heuristic with a 2-opt algorithm on top of that, guaranteeing us, at worst, to be at 1.5x the length of the optimal path.
- ItemConsumer Attitudes: Effect of the “Gender” of the Occupation and the Sales Associate’s Sex and Gender Expression on Attitudes Towards the Sales Associate(Florida Southern College, 2021-04-29) Francey, Eva M.; Henn, Rachel M.; Stiegler, Mallory D.; Goodmon, Leilani B.Current literature suggests that learned stereotypes may contribute to the development of certain attitudes and preferences toward gender nonconformity and, the more accepted, gender conformity (Boyce & Herd, 2003; Brescoll et al, 2010; Dozier, 2017; Embry et al, 2008; Heilman, 2012; McDowell, 2015; Ritter & Yoder, 2004; Swim et al, 2019). The current gap in research is the lack of crossing sex, gender expression, and employment to see how attitudes vary depending on gender conformity and nonconformity. The purpose of the current study was to determine how participants view retail associates who are gender congruent and incongruent at gendered retail stores to determine if the sex of the employee, the gender expression of the employee, and how masculine or feminine the workplace is stereotypically viewed impacts perceptions of the sales associate. Participants (N=121) were given depictions of the retail associates then completed the “Attitudes Towards Retail Associate Questionnaire” to assess perceptions of the sales associate’s authority, credibility, competency, comfortability. Our results contradicted most prior literature by not completely supporting Social Role Theory. For example, feminine females rated highest in the sports store with a score of 6.50. Continuing research in this field is important due to the pertinence it has on businesses and the economy. Businesses can utilize this information to better themselves and better understand how to reach more diverse target demographics who do not hold traditional gender views.
