Supplemental High-Tech Augmentative And Alternative Communication Experiences: A Study On Graduate Student Self-Efficacy, Confidence, And Knowledge With Pre-Service Training, Emily Sikes

Master's Theses

Providing assessment and intervention with high-tech augmentative and alternative communication is within the scope of practice of American Speech-Language Pathologists (SLPS). Therefore, SLPs should be able to properly identify and implement assessment, intervention, and caregiver coaching strategies in this area of practice. Due to the lack of confidence ratings of current SLPs in providing assessment and intervention in AAC that is found in current research, this study was designed to find plausible solutions for which confidence ratings can be increased beginning at the graduate level of a Speech-Pathology Master’s program. The researchers sought to answer the following questions: “Do students …

Gestalt Language Processing In Accredited Communication Sciences And Disorders Programs, William Harris

Master's Theses

The language development and usage of autistic individuals has become a controversial topic in many of the disciplines and professions providing support to these individuals. As a result, two theories of language processing have been proposed. Analytical language processing suggests that children process and develop language from its most simple form, a phoneme, to its most complex form, a word or phrase. However, the theory of gestalt language processing proposes that some children may instead extract larger, more complex language such as whole words and phrases first and break it down to the simpler language. Gestalt language processing is often …

How Speech-Language Pathologists Account For Self-Determination Across The Progression Of Dementia, Emilee Mcgahee

Master's Theses

Dementia diagnoses are continuing to increase, with the number of diagnoses expected to reach 231 million globally by 2050 (World Alzheimer’s Report, 2019). With this comes a greater need for Speech-Language Pathologists (SLPs) who are able to best treat those who are diagnosed. Providing person-centered and strengths-based treatment approaches for people with dementia (PWD) has been proven to increase positive engagement responses while decreasing negative engagement responses (Skrainer et al., 2007). The primary objective of this research study was to assess treatment approaches used by SLPs in dementia care setting, along with how SLPs provide person-centered dementia treatment throughout the …

Estimating Body Mass Through Bone Mineral Density Studies Using Dexa (Dual-Energy X-Ray Absorptiometry), Kaitlin Harstine

Master's Theses

Identification of a decedent is one of the primary goals of forensic anthropologists. In order to do this, one must build a biological profile based on the remains that are provided. Sex, age, ancestry, and stature are four of the most common, however a fifth addition piece of information that could be beneficial is body mass. The goal of this research is to explore the relationship between bone mineral density (BMD) and body mass, using data collected from dual x-ray absorptiometry (DEXA) scans of 107 collegiate football athletes. Athletes are a good fit for this study because they have achieved …

Acute Cardiovascular Response To Low-Load Unilateral, Bilateral, And Alternating Resistance Exercise With Blood Flow Restriction In The Lower Body, Daphney Stanford

Master's Theses

Resistance exercise with blood flow restriction (BFR) has been suggested to exaggerate the exercise pressor response over traditional non-BFR exercise. While applying BFR relative to an individual’s arterial occlusion pressure (AOP) and exercising at low-loads seems to produce a comparable cardiovascular response to traditional moderate or high-load training, it is beneficial to identify modifications for reducing the cardiovascular response to BFR exercise. PURPOSE: To determine if unilateral (UNI), bilateral (BI), or alternating (ALT) exercise modalities elicit different cardiovascular responses during BFR exercise. METHODS: 18 participants (13 male and 5 female) performed four sets of UNI, BI, and ALT knee-extensions at …

Posture Affects Affordance Perception Of Reachability In Virtual Reality, Hannah Masoner

Master's Theses

Tasks such as standing and reaching require differing levels of postural stability. Postural equilibrium is necessary to perceive the location of objects (Lee, Pacheco, & Newell, 2018). Visual perception of whether an object is within reach was investigated while standing upright. Participants viewed a 3D virtual reality (VR) environment with a stimulus object (red ball) placed at different egocentric distances. Participants made affordance judgements while in a standard stance condition as well as two separate active balance conditions (yoga tree pose, and toe-to-heel pose). Feedback on accuracy was not provided, and participants were not allowed to attempt to reach. Response …

Impact Of Prolonged Sitting On Cognitive Function: Implications For Cardio-Metabolic Risk, Sabina Miller

Master's Theses

Purpose: To determine if prolonged sitting negatively impacts cognitive function, cerebral perfusion, and central cardiovascular hemodynamics; and secondly, to test whether weight or physical activity status alters this response. Methods: Participants (N=20, age=26±7; BMI=30±7 kg/m²; 7 female) were taken through 3 hrs of sitting followed by a 10-min walk (treadmill). Cognitive function was assessed during sitting (10, 60, 120, and 180 mins) and following the walk using a color/word Stroop test. Cerebral perfusion was measured via near infrared spectroscopy (total hemoglobin—tHb). Central cardiovascular hemodynamics and aortic stiffness (pulse wave velocity—PWV) were measured using the SphygmoCor XCEL device before, …

Effects Of Prebiotics On Gut Bacterial Communities And Healing Of Induced Colitis In Mice, Krystyn Elizabeth Davis

Master's Theses

Inflammatory Bowel Diseases (IBD) cause chronic inflammation of the gastrointestinal tract and debilitating symptoms in those suffering from the diseases. After inducing colitis in a mouse model using Dextran Sulfate Sodium (DSS), prebiotics inulin and oligofructose enriched inulin (OEI) were used as treatments to determine their effects on the gut microbial community, physiological healing process, and immune response in the mice after initial inflammation and before subsequent inflammation, or relapse. The treatment with inulin led to an increase in regulatory T cell number, but this increase was not as significant as the increase induced by the OEI. Inulin increased the …

Personality And Relational Aggression In College Students: The Role Of Social Anxiety And Rejection Sensitivity, Daniel Locke Deason

Master's Theses

Relational aggression involves the intentional infliction of harm via damaging one’s relationships or sense of belonging. Previous research suggests that relational aggression among children and early adolescents is correlated with social ostracism, poor psychological adjustment, anxiety, and depression in victims, and there is increasing evidence that many of these correlates apply to relational aggression among older adolescents and emerging adults. Efforts to identify predictors of relational aggression are underway; however, many variables which have been influential in understanding other forms of aggression have not yet been examined. The Five Factor Model (FFM) of personality is one example, as it has …

The Effects Of The Tootling Intervention Using Daily Reinforcement, Melissa Bryanne Mchugh

Master's Theses

The current study was designed to replicate and extend the literature on the effectiveness of a classroom intervention known as Tootling (Skinner, Skinner, & Cashwell, 1998) in decreasing disruptive classroom behavior as well as increasing academically engaged classroom behavior. Tootling is a strategy that encourages and prompts students to report instances of their peers’ positive behaviors. Thus far, only three studies have utilized direct observation data for disruptive behavior during Tootling (Cihak, Kirk, & Boon, 2009; Lambert, 2012, 2014). To extend the research on Tootling, direct observation data of disruptive and academically engaged behaviors were collected on both entire classes …

Evaluation Of A Theory-Based Farm To School Program, Rebecca Kent Bishop

Master's Theses

Fruit and vegetable (FV) intakes in MS children remain lower than recommended. Theory-based, multi-component nutrition education interventions like Farm to School (F2S) target FV consumption and utilize such interventions to improve children’s dietary behaviors by incorporating nutrition and agriculture education. The current study was designed with Theory of Planned Behavior (TPB) as its framework. An intervention was implemented to enhance beliefs, norms, and self-efficacy regarding FV, thus potentially increasing the intention to consume more FV. The research objectives of this study are to describe changes over the course of the intervention in (1) nutrition knowledge; (2) norms, beliefs, and self-efficacy …

Propagation Of Oligomeric Α-Synuclein And Amyloid-Β: Implications For Parkinson's And Alzheimer's Diseases, Matthew Stephen Planchard

Master's Theses

The aggregation of amyloidogenic proteins is a critical event in the pathology of a variety of neurodegenerative diseases, including Alzheimer’s disease (AD) and Parkinson’s disease (PD). The proteins α-synuclein (αS) and amyloid-β (Aβ) are involved in the formation of amyloid lesions observed in PD and AD, respectively. Both PD and AD exhibit a significant amount of co-pathology in clinical settings, and the αS and Aβ proteins have been shown to interact in vitro. Recent experimental consensus has shown oligomeric species to be significant, if not primary, sources of toxicity in these diseases. …
