The following creative project defends that, whether intentionally or not, mental illness and substance abuse are inevitably romanticized in young adult media and discusses the dangers of this romanticization. This project is divided into three parts. The first part consists of psychological evaluations of the main characters of two popular, contemporary forms of young adult media, Catcher in the Rye by J.D Salinger and Euphoria by Sam Levinson. These evaluations use textual evidence and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) to determine what symptoms of psychopathology the characters appear to display. The second part consists of a self-written short story that is meant to accurately depict the life of a young adult struggling with mental illness and substance abuse. This story contains various aesthetic techniques borrowed from the two young adult media forms. The final part consists of an aesthetic statement which discusses in depth the aesthetic techniques employed within the short story, Quicksand by Anisha Mehra.
There is surprisingly little scientific literature describing whether a hockey slap shot positively or negatively transfers to a driving golf swing. Golf and hockey use a similar kinematic sequence to send the ball / puck towards a target, but does that directly translate to positive skill transfer between the two sports, or are there other important factors that could result in a negative skill transfer? The aim of this study is to look further into the two kinematic sequences and determine their intertask skill transfer type. A field experiment was conducted, following a specific research design, in order to compare performance between two groups, one being familiar with the skill that may transfer (hockey slapshot) and the other group being unfamiliar. Both groups had no experience in the skill being tested (driving golf swing) and various data was collected as all of the subjects performed 10 golf swings. The results of the data analysis showed that the group with experience in hockey had a higher variability of ball distance and ball speed. There are many factors of a hockey slapshot that are likely to develop a negative intertask skill transfer, resulting in this group's high inconsistency when performing a golf swing. On the other hand, the group with hockey experience also had higher mean club speed, showing that some aspects of the hockey slapshot resulted in a positive skill transfer, aiding their ability to perform a golf swing.
Introduction: Lateral reactive stepping is correlated with impairment in people with Parkinson’s Disease (PwPD). Despite this, there is little known of lateral stepping strategies and performance of these strategies in reactive stepping. Objective: To characterize step strategy in people with PD, characterize changes in these stepping strategies through training, and identify performance improvements in the lateral step strategies. Methods: A total of 31 PwPd who are currently at risk for falls took part in an 18-week various background reactive stepping intervention. The stepping strategies were assessed on two baseline assessments (B1 and B2) immediately followed by a 6- session step training intervention occurring over two weeks. Step strategies were again assessed immediately after training (P1) and two months later (P2). Initial outcomes were characterized step strategies, changes in step strategies, and improvement in performance of step strategies. Results: Three step strategies were established and split into two groups (no cross and cross). Changes in step strategies did not occur significantly both before and after training. Improvement in performance of the step strategies occurred at a significant amount (p=0.05) via a decrease in use of support after training occurred for any step strategies utilized. Conclusion: Step strategies were characterized, and performance of strategies was improved upon following the 2-week training. Lateral step strategies are defined and repeated throughout reactive step training with potential for improvement.
While REM Sleep Behavior disorder (RBD) has been linked with synucleinopathies, difficulties persist in clinically convenient diagnostic tools which can differentiate between underlying diseases. Identifying markers in the gait of RBD patients may ease the diagnostic process and indicate potential or status for developing more severe disorders. Individuals were referred to Movement Disorders Center of Arizona (MDCA) by a sleep specialist with a confirmed diagnosis of RBD, or those who were clinically indicated after questioning. All participants underwent a skin-biopsy test for α-synuclein, I-ioflupane dopamine transporter(DAT) scan, and had their gait velocity, cadence and stride dynamics assessed by an automated gait analysis system.
Parkinson’s Disease (PD) is characterized by involuntary tremors, muscle rigidity, slowed movement, and cognitive impairments. Some people with PD experience “Freezing of Gait” (FOG), which is an acute inability to release effective stepping. The severity of Freezing of Gait can be influenced by disease duration, disease severity, and medication. Freezing of Gait can lead to an increased risk of falls, mood disorders, reduced quality of life, poorer cognition, and executive function impairments (Morris et. al.). It is important to understand how Freezing of Gait can affect cognition, as this can alter the plan of cognitive rehabilitation that the patient receives in order to improve their cognition. Within each of these domains, are a variety of tests that all claim to measure the same cognition the same way and achieve similar results. A recent meta analysis assessed this hypothesized effect. However, to best understand this relationship, it is important to assess whether the effects of FOG status on cognition are similar across cognitive tests of the same domain. This research was performed by using a previously completed meta analysis on PD tests and the domains that tests fall into. Each of the domains were analyzed individually, and the most common tests used within each domain were compared to determine their effect sizes. The effect sizes were then compared to determine which tests have a greater influence on cognition, and if the effect sizes of each test within the same domain are similar, showing that FOG affects cognition to a similar degree.
The purpose of the present analysis was to (1) determine the DTI for absolute and percentage-based measures of gait and cognitive performance and (2) quantitatively characterize the prioritization between tasks for people with PD and healthy older controls. W evaluated a gait task and a cognitive task (backwards counting) during single-task and dual-task conditions in healthy older adults and patients with PD and noted their respective dual-task interference and prioritization scores. We found that this analysis does not totally support the literature that patients with PD will exhibit a Posture-Second strategy when presented with dual-tasking conditions. Instead, this analysis found that with both healthy older adults as well as adults with PD, there is an inconclusive Prioritization strategy utilized by both groups. The exception to this was the Male Controls, who exhibited a more Posture-First strategy. With the current knowledge, future research into Prioritization strategies for both healthy older adults and adults with Parkinson's should investigate the effect of Gender.
