The Art And Science Of Transition: A Descriptive Case Study Between A Two- And A Four-Year Institution, Kaylyn Marie Bondy

Theses and Dissertations

The vast majority of students who enroll in a two-year college intend to earn a bachelor’s degree. However, only about 14% transfer and earn a bachelor’s degree within six years (Jenkins & Fink, 2016). The need to increase the number of bachelor’s degree holders (Torpey, 2018), and the increasing number of students beginning at two-year institutions demands the creation of smoother transfer pathways (Handel, 2013). Vertical transfer students comprise a majority of transfer-related studies, however, little research has focused on the efficiency and efficacy of that process (Gard, Paton, & Gosselin, 2012). Institutions can strengthen transfer student resources with a …

The Impact Of Clinician Attachment Style On Burnout And Job Satisfaction: Introducing Mindfulness As A Mediator, Jill Marie Calderon

Theses and Dissertations

Attachment style is theorized to develop in childhood, as a result of the bonds that develop between child and caregiver. The research has shown individuals with an insecure attachment style are more at risk for job burnout and less satisfied with their jobs. This study proposed, mindfulness may be the internal process influencing the relationship between attachment style, burnout and job satisfaction. Mindfulness is defined as paying attention on purpose, in the present moment, nonjudgmentally and has found to be positively correlated with secure attachment styles. Additionally, mindfulness has shown to have a negative relationship with burnout and a positive …

The Role Of Candidate Gender And Political Support: An Experimental Approach To Understanding Voter Perceptions And Support For Female Presidential Candidates, Jenna Nichole Laurin

Theses and Dissertations

Female candidates are at a disadvantage in the political sphere, facing underrepresentation and stereotype hurdles at all levels of elected office. While female candidates have overcome some of these obstacles and won elections at the state and local levels, there has never been a female candidate elected President. The purpose of the current study was to determine whether female and male candidates are judged differently on measures of competence, warmth, traits, and willingness to vote. Employing a 2 (candidate gender) x 2 (participant gender) x 2 (candidate party) manipulation, 370 participants read a fictitious article about Presidential candidates and rated …

Dr. Andrew Foster's Contributions To Deaf Education In Africa, The Ghana Years (1957-1965), Joel Benjamin Runnels

Theses and Dissertations

Dr. Andrew Foster (1925-1987) was a Deaf African American missionary educator known to have established among the first 32 schools for the d/Deaf across 13 African nations. Foster tragically died in the 1987 Rwanda airplane accident. Deaf communities in Africa and the United States, soon after, lionized him as the “father of d/Deaf education in Africa”. Chroniclers of history largely ignored Foster and treated as invisible his contributions to d/Deaf education.

I had been waiting, like many, for researchers to give an in depth, historical treatment to Foster’s work. I felt knowledge from such a study would support me to …

Application Of Formal Specification Technique To Microgrid Representation, Maksym Tkach

Theses and Dissertations

This thesis uses formal specification techniques to analyze and model a microgrid. A microgrid is a small, local electrical grid, often supplied by a single generator, that can connect to the larger electrical grid, but can also disconnect from it, going into “island mode.” Thanks to the growth in renewable energy, microgrids represent a growing segment of the electrical power generation domain. And like any member of the domain they are safety-critical systems, meaning that even a small mistake in their implementation risks damage to life and property.Formal specification is a way to abrogate the risks of safety critical systems …

Asexual Experiences Of Microaggressions Scale: Instrument Development And Evaluation, Evelyn Estela Ayala

Theses and Dissertations

The present paper explores the experience of microaggressions among asexuals and relevant literature. There is a dearth of research on asexuality, particularly as it relates to the experience of microaggressions. However, research suggests that microaggressions have a cumulative impact on both physical and emotional well-being as reported by all minority groups that face microaggressions (Lewis, 2009, Mayer, 2010). The development of a scale that measures the experience of microaggressions would allow for this area of research to be further studied. The paper utilized DeVellis’s (2017) method for scale development to develop a psychometrically sound scale assessing the experience of microaggressions …

The Effects Of Modulating Accommodative-Vergence Stress Within The Context Of Operator Performance On Automated System Tasks, Kyle Anthony Bernhardt

Theses and Dissertations

Automated systems (e.g., self-driving cars, autopilot) can reduce an operator’s (i.e., driver, pilot, baggage screener) task engagement, which can result in mind wandering, distraction, and loss of concentration. Consequently, unfavorable performance outcomes, such as missed critical signals and slow responses to emergency events, can occur. Because automation reverts the operator to a “visual monitoring” role, the oculomotor accommodative-vergence responses (the oculomotor responses that maintain a single focused image on the retina) may play a vital role in human-automation interactions. Prior research has shown that individuals with deficits in the accommodative-vergence responses can exhibit inattentive symptoms (e.g., poor concentration) characteristic of …

School-Aged Children With Severe Disabilities And Limited Verbal Language: Exploring The Importance Of Social Interactions And Friendship, And Its Application In Practice, Kristina Brodal Syversen

Theses and Dissertations

Social interactions and friendships with peers have been found to be essential to children’s and adolescents’ development, learning, and overall quality of life. However, research shows children and adolescents with severe disabilities and limited verbal language have fewer friendships and quality social interaction with peers than those without disabilities. This still occurs today, despite the implementation of the Least Restrictive Environment (LRE) legislation in 1978. One of the goals of the LRE was to maximize the opportunities children and adolescents with disabilities have when it comes to social interactions with peers in the general education classroom. However, as the general …

Self Me: An Examination Of Social Media Usage On The Self-Authorship Of College Students, Sherry Lawdermilt

Theses and Dissertations

This study examined the effects of social media usage on the self-authorship of college students. Social media as a means for social interaction has become a constant in the life of young adults. At a time when students have traditionally established their own beliefs and identity and begin to move towards self-authorship, these social mediums have become a venue for students to look to others for a definition of who they are or who they want to be. Current literature on college students’ use of social media has focused on the relationship between social media usage and online social behavior, …

At-Home Childcare Providers’ Perceptions Of Gardening With Children, Erin Lauckner

Theses and Dissertations

Children do not consume recommended amounts of fruits and vegetables, which has been correlated with negative health consequences. Gardening with children has been shown to positively impact children’s consumption of these foods. While research investigating gardening with children exists, much of this has been conducted with teachers and children in schools, and limited research has been conducted with childcare providers and preschool-aged children. Little research has been conducted about this topic with in-home childcare providers and the children under their care.

The Value Of Existential Worlds: Creation And Validation Of A Measure To Explore The Four Existential Worlds, Matthew Robert Rozzi

Theses and Dissertations

The field of counseling psychology is increasingly focused on understanding clients in holistic and non-pathologizing ways. Existential theory provides the four-worlds model for exploring human existence in line with this modern psychological zeitgeist. In this model, humans are understood to exist simultaneously in four “worlds” or “dimensions”: physical (umwelt), social (mitwelt), psychological (eigenwelt), and spiritual/philosophical (uberwelt). This measure construction project is the first known study to examine the personal importance (value) of existing in each world. The Value of Existential Worlds (VEW) was created and psychometrically examined. From the initial 63-items, a shorter (20-item) version was created which demonstrated a …

Exploration Of Model-Resolution Dependence Of Forecasted Wind Hazards For Small Unmanned Aircraft System Operations, Lucas Andrew Reilly

Theses and Dissertations

Use of the small Unmanned Aircraft System (sUAS) for commercial applications is growing. Once approval is granted to conduct flights Beyond Visual Line Of Sight (BVLOS), utilization of the sUAS will accelerate. Hazards associated with sUAS flight, including weather hazards, must be understood when flying BVLOS. One of the leading weather hazards is wind. In this study, nested Weather Research and Forecasting (WRF) model simulations with horizontal grid spacings of 12 km, 4 km, 1.33 km, and 0.444 km were conducted to evaluate the impact changing resolution has on wind fields and, thus, on the forecasting of sUAS wind hazards. …

Examining College Students’ Emotions And Alcohol Usage On A College Campus: Student Chemical Assessment And Review Program (Scarp), Thomas William Solem

Theses and Dissertations

Alcohol use and abuse is an important issue amongst college students, and the totality of impacts are still misunderstood. Identification of high-risk alcohol abuse problems leads universities to intervene; however, the emotional, personal, and academic impacts of such mandated intervention programs is unclear. Helping universities understand students’ alcohol abuse challenges can aid appropriate interventions, as well as improve student well-being and academic success.

The purpose of this study is to examine the Student Chemical Assessment Review Program (SCARP), specifically to explore its impacts on student variables (university motivation, readiness/importance of confidence to change, self-esteem, guilt, shame, depression, anxiety, and resiliency) …

Lyme disease, caused by the spirochete Borrelia burgdorferi (Bb), is the most commonly reported vector-borne disease in the United States – with 30,000 cases being reported to the CDC annually, though it is estimated that 300,000 individuals are infected each year in the U.S [1–4]. Due to the medical treatment of the disease, this equates to an estimated $712 million - $1.3 billion in medical costs each year [5]. Conclusively, due to the continued geographical spread and increasing incidence rate, Lyme disease is becoming a greater public health threat throughout the world.

The symptoms of Lyme disease can range from …

Instructional Coaching: Self-Efficacy, Resilience, And Joy, Aimee Marie Volk

Theses and Dissertations

At the time of this study, research on instructional coaching suggests positive outcomes for teacher retention and student achievement. However, merely providing an instructional coach to support a teacher is not sufficient. Effective coaching programs are built around foundational, structural, and instructional coaching program standards as well as employ coaches who are capable and effective in a multitude of content, instructional, and behavioral situations. Research illustrates that coaches vary significantly in effectiveness. Therefore, coaching outcomes may produce inconsistent results among various coaching programs and even between individual schools within the same school district. In other words, not all coaches or …

Theses and Dissertations

Occupational therapy programs are currently pursuing the transition to an entry-level occupational therapy doctorate (OTD). Due to the novel change with this population, minimal research exists on how faculty are understanding and constructing a process to manage stress, promote wellbeing, and foster self-efficacy for themselves and the benefit of students during this time of transition. The concepts of habituation and social cognitive theory frame inquiry and understanding of the research problem for the development of a constructivist grounded theory study. A total of nine faculty and staff members at a Midwest OT program in the midst of programmatic change to …

The Relationship Between Saudi Citizen Perceptions Of Vision 2030 And Saudi Government Social Media Use To Promote Vision 2030, Essa Saleh Alkathiri

Theses and Dissertations

Public relations (PR) tools have enabled more communication between governments and citizens in the whole world. However, a single communication channel could be widespread among many governments. These PR tools help governments to share national goals, projects, and programs with their citizens. Grunig and Hunt (1984) highlighted that the value of two-way communication channels is better suited to develop an understanding between public organizations (i.e. governments) and citizens to establish both internal and external mutual public-organization or citizen-government understanding. However, the practical implementation of two-way communication channels for the government-citizen relationships and dialog remains is unclear. As a result, the …

To evaluate changes in the saliency and public interest in these tragedies, this two-part study 1) utilized open access data from Wikipedia and 2) measured the presence of flashbulb memories (FBM) for these events.

Methods: For Part I, changes in byte size and edits in 19 mass shooting Wikipedia articles were examined over 12 months to determine public interest in these events. In Part II, 500 participants …

Deepmag+ : Sniffing Mobile Apps In Magnetic Field Through Deep Learning, Rui Ning, Cong Wang, Chunsheng Xin, Jiang Li, Hongyi Wu

Electrical & Computer Engineering Faculty Publications

This paper reports a new side-channel attack to smartphones using the unrestricted magnetic sensor data. We demonstrate that attackers can effectively infer the Apps being used on a smartphone with an accuracy of over 80%, through training a deep Convolutional Neural Networks (CNN). Various signal processing strategies have been studied for feature extractions, including a tempogram based scheme. Moreover, by further exploiting the unrestricted motion sensor to cluster magnetometer data, the sniffing accuracy can increase to as high as 98%. To mitigate such attacks, we propose a noise injection scheme that can effectively reduce the App sniffing accuracy to only …

A New Method Of Detecting And Interrupting High Impedance Faults By Specifying The Z-Source Breaker In Dc Power Networks, Sagar Bhatta, Ruiyun Fu, Yucheng Zhang

Electrical & Computer Engineering Faculty Publications

High impedance faults (HIFs) that cause a relatively smaller current magnitude compared to the traditional low impedance faults are not easily detectable but can cause an extreme threat to electric apparatus and system operation. This paper introduces a new method of detecting and interrupting HIFs in DC power networks by specifying Z-source circuit breakers (ZCBs). The ZCB is a protective device for high power DC branches, with the capabilities of protecting bidirectional power flow and automatic/controllable turnoff function. In this new method, the operational mode of ZCB (i.e., either the detection mode or interruption mode) can be specified. Beyond previous …
