Success Rate Of Student Accessibility Services Determined By Students Cumulative Grade Point Average, Christine Brown
Electronic Theses and Dissertations
Background: National studies have previously found that those within the disabled population are underserved in regard to healthcare, education, employment and medical access. Historically, the majority of those who are disabled due to this engrained inequality receive government assistance. Multiple laws have been enacted to protect those who fall into this minority such as ADA, section 504 and IDEA. These laws ensure the disabled equal access to employment, public services, education, public accommodations and telecommunications. Federally funded departments called student disability services (SDS) are on college/university campuses to ensure equal access and treatment throughout a student's college career. Under the …

Energy Expenditure And Stability During Self-Paced Walking On Different Slopes, Alanna Raffaelli
Electronic Theses and Dissertations
Metabolic power and cost of transport (COT) are common quantifiers for effort when performing tasks including walking and running. Most studies focus on using a range of normal walking speeds over level ground or varied slopes. However, these studies use fixed-speed conditions. Fatigue, stability, metabolic expenditure, heart rate, and many other factors contribute to normal walking speed varying over time. This study aimed to show that allowing a subject to walk with a self-paced speed should correlate to a minimum COT at a given slope. This study also aimed to determine if a preferred slope exists based on minimizing metabolic …

In this study, we propose two different modeling frameworks using Deep Long Short-Term Memory Neural Network (LSTM NN) model to predict future traffic state (speed and signal queue length). In our first problem, we present a modeling framework using deep LSTM NN model to predict traffic speeds in freeways during regular traffic condition as well as under extreme traffic demand, such …
Readability Of Patient-Reported Outcome Measures For Persons With Aphasia, Sara Gray
Readability Of Patient-Reported Outcome Measures For Persons With Aphasia, Sara Gray
Electronic Theses and Dissertations
The relationship between positive health outcomes in persons with aphasia (PWA) and personcentered care is highlighted by personally relevant information obtained directly from the PWA. Such is often facilitated via patient reported outcome measures (PROMs). In order to provide accurate responses to PROMs, PWAs must to read, comprehend, formulate and generate answers to a variety of questions. PROMs designed for other clinical populations assessed/treated by speech-language pathologists have been found to be largely unreadable. Despite the significant role of PROMs in assessment and management of aphasia, no study to date has examined the readability of these measures. Four readability formulae …

The Religious Classroom: Analyzing The Cross-Application Of Instructional Communication Pedagogy To Youth Ministries, Lakelyn Taylor
The Religious Classroom: Analyzing The Cross-Application Of Instructional Communication Pedagogy To Youth Ministries, Lakelyn Taylor
Electronic Theses and Dissertations
Instructional communication literature suggests that, to achieve optimal student learning outcomes, an instructor must completely engage in all aspects of experiential learning. It follows, then, that youth ministers should also employ experiential learning in their youth ministries to achieve their learning outcome goals among the youth they teach. This research project examined three research questions: 1.) What pedagogical strategies do youth ministers use during large group class sessions? 2.) In what ways do youth ministers employ instructional communication best practices within their pedagogical strategies? 3.) What strategies do former students remember their youth minister using the most? The analysis revealed …

Mediated Physicality: Inducing Illusory Physicality Of Virtual Humans Via Their Interactions With Physical Objects, Myungho Lee
Mediated Physicality: Inducing Illusory Physicality Of Virtual Humans Via Their Interactions With Physical Objects, Myungho Lee
Electronic Theses and Dissertations
The term virtual human (VH) generally refers to a human-like entity comprised of computer graphics and/or physical body. In the associated research literature, a VH can be further classified as an avatar - a human-controlled VH, or an agent - a computer-controlled VH. Because of the resemblance with humans, people naturally distinguish them from non-human objects, and often treat them in ways similar to real humans. Sometimes people develop a sense of co-presence or social presence with the VH - a phenomenon that is often exploited for training simulations where the VH assumes the role of a human. Prior research …
Machine Learning From Casual Conversation, Awrad Mohammed Ali
Machine Learning From Casual Conversation, Awrad Mohammed Ali
Electronic Theses and Dissertations
Human social learning is an effective process that has inspired many existing machine learning techniques, such as learning from observation and learning by demonstration. In this dissertation, we introduce another form of social learning, Learning from a Casual Conversation (LCC). LCC is an open-ended machine learning system in which an artificially intelligent agent learns from an extended dialog with a human. Our system enables the agent to incorporate changes into its knowledge base, based on the human's conversational text input. This system emulates how humans learn from each other through a dialog. LCC closes the gap in the current research …
Quality Diversity: Harnessing Evolution To Generate A Diversity Of High-Performing Solutions, Justin Pugh
Quality Diversity: Harnessing Evolution To Generate A Diversity Of High-Performing Solutions, Justin Pugh
Electronic Theses and Dissertations
Evolution in nature has designed countless solutions to innumerable interconnected problems, giving birth to the impressive array of complex modern life observed today. Inspired by this success, the practice of evolutionary computation (EC) abstracts evolution artificially as a search operator to find solutions to problems of interest primarily through the adaptive mechanism of survival of the fittest, where stronger candidates are pursued at the expense of weaker ones until a solution of satisfying quality emerges. At the same time, research in open-ended evolution (OEE) draws different lessons from nature, seeking to identify and recreate processes that lead to the type …

Group Composition Characteristics As Predictors Of Shared Leadership: An Exploration Of Competing Models Of Shared Leadership Emergence, Richard Currie
Electronic Theses and Dissertations
The study of leadership in organizations has received much research attention over the past several decades. However, most of this research has examined hierarchical structures of leadership wherein one individual leads, or is perceived to lead, several other individuals. With a growing number of organizations structuring employees within teams or work groups, researchers have begun studying the ways in which leadership operates in groups. One alternative to the traditional hierarchical structure is for leadership to be distributed or shared in groups such that multiple group members contribute to the overall leadership function of the group. As a result, researchers have …

Streamflow Prediction In Ungauged Basins Located Within Data-Scarce Regions, Mohammadhossein Alipour
Electronic Theses and Dissertations
Preservation and or restoration of riverine ecosystem requires quantification of alterations inflicted by water resources development projects. Long records of streamflow data are the first piece of information required in order to enable this analysis. Ungauged catchments located within data-scarce regions lack long records of streamflow data. In this dissertation, a multi-objective framework named Streamflow Prediction under Extreme Data-scarcity (SPED) is proposed for streamflow prediction in ungauged catchments located within large-scale regions of minimal hydrometeorologic observation. Multi-objective nature of SPED allows for balancing runoff efficiency with selection of parameter values that resemble catchment physical characteristics. Uncertain and low-resolution information are …

Vibration Reduction Of Mistuned Bladed Disks Via Piezoelectric-Based Resonance Frequency Detuning, Garrett Lopp
Vibration Reduction Of Mistuned Bladed Disks Via Piezoelectric-Based Resonance Frequency Detuning, Garrett Lopp
Electronic Theses and Dissertations
Recent trends in turbomachinery blade technology have led to increased use of monolithically constructed bladed disks (blisks). Although offering a wealth of performance benefits, this construction removes the blade-attachment interface present in the conventional design, thus unintentionally removing a source of friction-based damping needed to counteract large vibrations during resonance passages. This issue is further exacerbated in the presence of blade mistuning that arises from small imperfections from otherwise identical blades and are unavoidable as they originate from manufacturing tolerances and operational wear over the lifespan of the engine. Mistuning is known to induce vibration localization with large vibration amplitudes …
The Examination Of A Mobile Application For The Reduction Of Posttraumatic Stress Related Symptoms In Emergency Dispatchers, Emy Willis
Electronic Theses and Dissertations
Emergency dispatchers report that their jobs are stressful, yet there are few controlled investigations examining their specific psychological complaints. Additionally, research examining the use of interventions directed at alleviating their work-related stress is limited. This study aims to examine the efficacy and feasibility of a mobile application (PTSD Coach) on various indicators of psychosocial well-being among emergency telecommunicator dispatchers. A sample of 117 emergency dispatchers completed self-report psychological mood assessments at baseline, weekly for five weeks during PTSD Coach use and post-treatment.

Novel Fuel-Producing Fungi And Methodologies For Increasing Fuel Production, Yuemin Wang Kovaleff
Electronic Theses and Dissertations
An endophytic fungus Hypoxylon sp. (BS15) has recently been isolated and found to produce volatile organic compounds (VOCs) that have potential relevance as hydrocarbon fuels. In the work described here, the traditional refined carbohydrate (e.g., sucrose) diet source was replaced by simple sugars produced using a solvent free green chemistry mechanocatalytic method involving ball milling in the solid. BS15 is able to grow on this degraded cellulose as well as the more traditional potato dextrose broth. The volatile compounds produced from both media were largely the same. Unfortunately, it is observed that long term in vitro growth of BS15 results …
