An Athletic Approach To Studying Perception-Action Integration: Does Sport-Specific Training, And The Impact Of Injury, Influence How Individuals Visually Guide Navigation?, Carmen Baker, Jennifer Campos Ph.D, Michael E. Cinelli Ph.D.

Theses and Dissertations (Comprehensive)

The objective of this thesis was to investigate perception-action integration capabilities of individuals during a choice navigation task. This task assessed navigation strategies in open space while individuals avoided colliding with two vertical obstacles that created a body-scaled, horizontal gap, at three varying obstacle distances from the starting location (3m, 5m, 7m). The two studies completed in this thesis employed the same paradigm to assess the hypothesized group differences. Gaze behaviours and kinematics of navigation strategies were compared between: 1) athletes specifically trained in navigating in open space versus non-athletes; and 2) athletes with post-concussion syndrome (PCS) versus non-concussed, specifically …

Transient Trunk Flexion: The Potential To Alleviate Low Back Pain During Prolonged Standing, Danielle M. Stewart

Theses and Dissertations (Comprehensive)

The current study examined potential benefits of intermittent, short-term periods of full trunk flexion on the development of low back pain (LBP) over two hours of standing. Sixteen participants completed a 2-hour standing protocol, on two separate days. On one day, participants stood statically for 2 hours; on the other day participants bent forward to full spine flexion for 5 seconds every 15-minutes. During both protocols, participants reported LBP using a 100mm visual analogue scale every 15-minutes. During the flexion trials, erector spinae muscle activation was monitored. Ultimately, intermittent trunk flexion reduced LBP by 36% (10mm) at the end of …

The Effect Of Training Older Adults In Tai Chi And Compensatory Stepping On Balance Control, Hannah L. Moore Miss

Theses and Dissertations (Comprehensive)

Abstract

Introduction: In Canadian society, there is a growing prevalence of older adults and one of the main problems facing this generation today is the risk of falling. Tai Chi (TC) is a martial art that has demonstrated improvements in balance control. It uses a series of fluid movements that engage head, neck and trunk rotation while simultaneously reducing base of support. In addition, it has been demonstrated that training older adults by administering unpredictable perturbations to challenge balance better equips them to react successfully in response to balance perturbations. This study aims to determine the potential balance specific benefits …

A New Obesity Model Reveals The Hypophagic Properties Of Pacap Involve The Regulation Of Homeostatic Feeding In The Ventromedial Hypothalamic Nucleus And Hedonic Feeding In The Nucleus Accumbens, Matthew M. Hurley, Brian Maunze, Jon M. Resch, Mogen M. Frenkel, M. J. Reilley, Megan E. Block, David A. Baker, Sujean Choi

Biomedical Sciences Faculty Research and Publications

Binge eating in humans is a complex disorder that often involves discrete, compulsive feeding sessions of highly palatable foods even in the absence of a deprivation state or hunger. Binging can be effectively modeled in rodents by providing subjects with limited access to a palatable food source (Western Diet; WD) as an adjunct to ad lib access to normal chow (Standard Chow; SC). Although this design recapitulates several fundamental characteristics observed in binge eating disorder, the binge eating observed in this paradigm is likely a product of both hedonic and homeostatic drives with the need to balance energy stores still …

A Phenomenological Study: Marriage And Family Therapists' And Clinician's Perceptions Of How Secondary Traumatic Stress Affects Them And Their Families, Norja Elizabeth Cunningham

Antioch University Dissertations & Theses

Multiple facets of clinicians' lives are influenced by compassion fatigue including physiological well-being, the perspective of clinicians in relation to the world, and psychological and emotional reactions to trauma triggers (Figley, 1998). Work stress research considers the systemic effects of stress on workers' relationships. Research also shows that romantic relationships are negatively influenced by work stress (Sanz-Vergel, Rodriguez, Bakker & Demerouti, 2012). This phenomenological study investigated the lived experience of three clinicians and how compassion fatigue was experienced in their relationships with their partners and children. Clinicians completed the Professional Quality of Life assessment and those with a score of …

Antioch University Dissertations & Theses

As Indigenous peoples, we have a responsibility to our global community to share our collective truths and experiences, but we also deserve the respect to not be objectified, essentialized, and reified. Today, we are in a period of continual Native resurgence as many of us (re)member our prayers, songs, languages, histories, teachings, everyday stories and our deepest wisdom and understanding as Indigenous peoples--we are all “living breath” and we are “all related.” For eight years, Carmella Rodriguez and I have been nDigiStorytelling across the United States and have co-created over 1,200 digital stories with over 80 tribes for Native survivance, …

Common Psychosocial And Spiritual Factors Among Individuals Who Have Healed From Chronic Lyme Disease, Frederick Green

Antioch University Dissertations & Theses

This dissertation examined the subjective experience of individuals who have healed from Chronic Lyme Disease (CLD). Despite significant attention paid to the controversy over CLD diagnosis and treatment, scholarly research has neglected the psychosocial and/or spiritual factors that facilitate healing from the perspective of CLD sufferers. This study addressed this research gap by using Interpretive Phenomenological Analysis (IPA) to explore the barriers and facilitators of healing among those who have healed from CLD. Six participants who had suffered from CLD and considered themselves healed from the disease were recruited and interviewed. The qualitative data was reduced to meaning units, which …

Upper extremity joint kinematics, forces, and moments were computed using …

The Impact Of Climate Change On Human Health, Mary Snow, Richard Snow

Publications

Climate change is impacting human health. An obvious effect of a warmer environment is more frequent and severe heat waves. During the European heat wave of 2003, there were an estimated 35,000 more deaths than normal in the first two weeks of August. Many of the deaths resulted from cardiovascular complications among the elderly. As heat waves become more commonplace in the future, so will the number of heat strokes and the onset of other cardiovascular problems. Higher summertime temperatures also increase tropospheric ozone concentrations which in turn affects people with asthma and causes lung and heart damage. Increases in …

Missing Photos, Suffering Withdrawal, Or Finding Freedom? How Experiences Of Social Media Non-Use Influence The Likelihood Of Reversion, Eric P.S. Baumer, Shion Guha Phd, Emily Quan, David Mimno, Geri K. Gay

Health Services and Informatics Research

This article examines social media reversion, when a user intentionally ceases using a social media site but then later resumes use of the site. We analyze a convenience sample of survey data from people who volunteered to stay off Facebook for 99 days but, in some cases, returned before that time. We conduct three separate analyses to triangulate on the phenomenon of reversion: simple quantitative predictors of reversion, factor analysis of adjectives used by respondents to describe their experiences of not using Facebook, and statistical topic analysis of free-text responses. Significant factors predicting either increased or decreased likelihood of reversion …

Research outputs 2014 to 2021

Metastatic melanoma is a highly heterogeneous tumor; thus, methods to analyze tumor-derived cells circulating in blood should address this diversity. Taking this into account, we analyzed, using multiparametric flow cytometry, the co-expression of the melanoma markers melanoma cell adhesion molecule and melanoma-associated chondroitin sulphate proteoglycan and the tumor-initiating markers ATP-binding cassette sub-family B member 5 (ABCB5), CD271, and receptor activator of NF-κβ (RANK) in individual circulating tumor cells (CTCs) from 40 late-stage (III-IV) and 16 early-stage (I-II) melanoma patients. CTCs were heterogeneous within and between patients, with limited co-expression between the five markers analyzed. Analysis of patient matched blood and …
