Concurrent Load And Construal On Planning, Maximilian Fey

Graduate Theses and Dissertations

Planning for the future is a necessary activity which spans across all aspects of an individual’s life. Concurrent cognitive load has been shown to hinder future planning, whereas concrete construal of events has been shown to increase planning efficacy. Interestingly, a limited literature speaks towards cognitive load inducing concrete construal. However, the two constructs predict differing outcomes on future planning therefore the interaction of cognitive load inducing a concrete construal is particularly interesting. The research study tested whether differing levels of concurrent cognitive load increase or decrease planning efficacy. The intention of the research was to elucidate whether cognitive load …

Modeling Damage Spread, Assessment, And Recovery Of Critical Systems, Justin Burns

Graduate Theses and Dissertations

Critical infrastructure systems have recently become more vulnerable to attacks on their data systems through internet connectivity. If an attacker is successful in breaching a system’s defenses, it is imperative that operations are restored to the system as quickly as possible. This thesis focuses on damage assessment and recovery following an attack. A literature review is first conducted on work done in both database protection and critical infrastructure protection, then the thesis defines how damage affects the relationships between data and software. Then, the thesis proposes a model using a graph construction to show the cascading affects within a system …

Macronutrient Availability Shapes Host Response To Infection And Feeding Behavior, Weston Gerald Perrine

Graduate Theses and Dissertations

Macronutrients in the diet are vital to the physiological processes necessary for an organism to effectively clear a pathogen. Diet can be important to a host’s susceptibility to infection and severity of pathology, though results can vary across host-pathogen systems (Sen et al. 2016). Manipulating the ratio of specific macronutrients in the diet is an effective method to begin understanding how individual macronutrients, rather than food types, have on immune responses. Using an avian host-pathogen system, I explored the effects of dietary macronutrient composition, specifically lipid and protein content, on disease pathology and behavior of canaries (Serinus canaria) infected with …

Post-Obergefell V. Hodges: How Lgbt Contact Can Alter Public Lgbt Policy Positions In The U.S. And Arkansas, Briana Huett

Graduate Theses and Dissertations

The Contact Theory (CT) of attitudinal change has utilized to understand perceptions of minority-group members and the policies that surround them since the 1950s. It has further been used to specifically examine how we form our opinions of LGBT-identifying individuals, the LGBT community, and LGBT policies more generally. However, further evidence is still needed from the CT literature surrounding how this form of contact interacts with individuals’ social identities to determine and alter their LGBT policy positions, how the level of contact with LGBT persons might have differing effects on these positions, and whether LGBT contact holds the same effects …

How Do Virtual Social Media Influencers Affect Millennial And Gen Z Female Consumers’ Purchase Intention? A Comparison Of Fast Fashion Versus Luxury Fashion Brands, Lauren Bouvier

Graduate Theses and Dissertations

With the emergence and increasing prevalence of social media, the effectiveness of social media influencers (SMIs) is apparent in today’s fast-paced life. Virtual social media influencers (VSMIs), computer-generated influencers with a real human appearance, have gained popularity. The purpose of this study is to examine important VSMI’s characteristics that affect brand image and trust which lead to purchase intention (fast fashion vs. luxury fashion brand). Social exchange theory and source credibility model were adopted to develop a theoretical framework for the present study. Two Instagram ads were developed that included the post’s image and corresponding caption: VSMI endorsing H&M and …

A Mixed Methods Approach To Context Specific Curriculum Design For Very Small And Small Strawberry Growers In The Southeastern United States, Thomas A. Yeargin

Graduate Theses and Dissertations

Outbreaks of foodborne illness due to fresh produce are a continued threat to both the publichealth and the economy in the United States. Though there are many factors which influence the perpetuation of foodborne pathogens, the inability of the food industry to curtail this issue indicates systemic failure of interventions aimed at improving food safety practices. In this dissertation, we detail the efforts made over the past few decades to provide training to food producers and food handlers as well as recommendations that have been made for improvement based on these studies. By borrowing from more advanced fields of study …

Examining The Association Between Fictive Kin Care, Parental Attachment And Emotional Distress In College Students, Roxanne Watts

Master's Theses

Having a supportive and secure relationship with parents can predict less emotional distress in college students. In addition to parental support, many families leverage fictive kin caregivers to provide support. This is especially true in communities of racial and ethnic minorities. The present study investigated the association between fictive kin care, parental relationships, and emotional distress in college students. One hundred fourteen (N = 114) college students completed measures that assessed parental and fictive-kin relationships, social support, and emotional distress. A COVID-19 pandemic-related distress measure was also administered. Three hypotheses were tested. First, it was hypothesized that fictive kin …

The Plague And The Parthenon: Crusade, Climate Change And Disease In The Early Modern Mediterranean, John Mark Nicovich

Master's Theses

The present study examines the role epidemic diseases, specifically malaria and bubonic plague, played on the course of the Morean War (1684-1699). The Morean War was a major offensive by Christian powers, led by the Venetian Republic, against Ottoman controlled Greece. Christian victories during the war were widely celebrated across western Europe, but even in victory Christian forces took severe casualties from multiple disease outbreaks. First, this study seeks to explain the terrestrial and maritime networks the war was fought over, and how those networks either led the opposing forces into regions of endemic disease (malaria), or how they allowed …

Teaching Old Calipers New Tricks: Using Craniometrics For Ancestry Admixture Estimation Via Fuzzy Math, Kristi Carnahan

Master's Theses

Cranial measurements have been a cornerstone of physical anthropology since its formation as a discipline in the early 1900s. However, most other ancestry determination methods come with a significant epistemological issue: they differentiate individuals into discrete categories without accounting for the issue of admixture. Advances in data mining and analysis techniques can now be used to help resolve this issue through soft computing, also known as “fuzzy math”. This type of advanced computational math requires specialized knowledge in computer programming, statistics, and data analysis techniques unless one is using computer programs specially designed to run these analyses.

Dentistry And The Law: What Is Illegal About Disclosing Fee Schedules?, Dan Schulte Jd

The Journal of the Michigan Dental Association

This Dentistry and the Law column addresses the question of disclosing fee schedules by dental plans. The author clarifies that dental plans often withhold fee schedule information, citing potential antitrust violations or illegality. However, the column asserts that this is an excuse rather than a legal constraint. The author explains that disclosing fee schedules does not violate antitrust laws; violations occur through agreements that unreasonably restrain competition. The reluctance of dental plans to disclose fee information is attributed to business objectives, not legal concerns. Dentists are encouraged to request fee schedules to make informed decisions about network participation, with a …

10-Minute Ebd: Charcoal Toothpastes Pose Risks With Few Benefits, Kelly Lemke Dds, Ms

The Journal of the Michigan Dental Association

The rising popularity of charcoal toothpaste, fueled by social media influencers and claims of teeth-whitening benefits, prompts an investigation into its effectiveness and potential risks. The article explores the evidence through a PICO (Population, Intervention, Comparison, Outcome) question focused on patients seeking whiter teeth. A literature review reveals limited scientific validation for the cosmetic or health benefits of charcoal-containing oral products. The abrasiveness of charcoal toothpaste poses risks, potentially leading to enamel loss, dentin exposure, and hypersensitivity. Lack of fluoride in many charcoal toothpaste formulations raises concerns about caries risk. The article emphasizes the importance of dental providers conducting due …

Murine exercise models can provide information on factors that influence muscle adaptability with aging, but few translatable solutions exist. Progressive weighted wheel running (PoWeR) is a simple, voluntary, low-cost, high-volume endurance/resistance exercise approach for training young mice. In the current investigation, aged mice (22-mo-old) underwent a modified version of PoWeR for 8 wk. Muscle functional, cellular, biochemical, transcriptional, and myonuclear DNA methylation analyses provide an encompassing picture of how muscle from aged mice responds to high-volume combined training. Mice run 6–8 km/d, and relative to sedentary mice, PoWeR increases plantarflexor muscle strength. The oxidative soleus of aged mice responds to …

A Model For The Pastor Search Process For Free Will Baptist Churches, Timothy Buckley York

Doctoral Dissertations and Projects

This project sought to help the pastor shortage in the National Association of Free Will Baptists by creating and implementing a tool to assist churches in their search for a pastor and help pastors find a new church to serve. Each church in the association is autonomous and selects its own pastor. The tool is actually two surveys that mirror each other. The churches seeking a pastor completes the church survey. And the candidate seeking a church to pastor completes the pastor survey. The tool gives information and views of ministry roles, preferences, non-negotiables, and negotiables. It is designed to …

Middle School Staffs' Perceptions Of Bullying And Traumatization Of Special Education Students In An Alternative School Setting, Marlene Williams

Doctoral Dissertations and Projects

The purpose of this qualitative hermeneutic phenomenological study is to know and understand teachers’ perceptions of bullying, teachers’ perceptions of special education students, and what influences their decision to intervene and assist when observing special education students being victimized through bullying. The theory guiding this study is Aaron Beck’s Cognitive Behavioral Theory’s Cognitive Triangle that suggests that thought influences emotions and emotions influences behaviors, as well in reverse. The data collection process includes individual interviews with eight classroom teachers who work in alternative middle schools. Due to COVID-19, in-person observations were omitted, and the individual interviews were conducted using Zoom …

Sense Of Purpose, Self-Efficacy And Problem-Focused Coping As Predictors Of Mental Health Clinician Burnout, Launa Ashley Duffy

Doctoral Dissertations and Projects

Burnout has been an area of interest in research since the 1970s. However, the World Health Organization (2019) only recently determined the state of being occupationally burned out was indeed worthy of differential criteria. Research on the impact a sense of purpose has on a mental health professionals’ experience of burnout promises to deliver a new understanding of this syndrome. Some studies have stressed that due to the many positive results observed when an individual has a sense of purpose, a sense of purpose can only reduce the presence of burnout. However, a sense of purpose can also influence factors …

C. I. Scofield's Teachings Regarding The Conversion And Restoration Of The Jewish Nation In Fulfillment Of Old And New Testament Prophecies And Their Potential Apologetic Value, Timothy M. Skinner

Doctoral Dissertations and Projects

The confirmation of C. I. Scofield's beliefs and teachings regarding a literal and national restoration of the Jewish people in fulfillment of Old and New Testament prophecies can be argued through the writings of Reformed theologians and those hostile to dispensationalism by utilizing a comparative biblical/theological approach on a key eschatological passage, Romans 11:26 and the statement, “All Israel shall be saved.” Non-dispensationalists acknowledge or are in agreement with many of the teachings of Scofield but reject his conclusions regarding the restoration of a literal Jewish nation as being proof of the proper interpretation of the biblical text, even though …

Nutrient Uptake And Water Quality In Great Salt Lake Wetland Impoundments, Rachel L. Buck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Great Salt Lake (GSL) is the largest inland body of water on the Pacific flyway, a major pathway for migratory birds in the Americas that extends from Alaska to Patagonia. The lake is surrounded by approximately 360,000 acres of wetlands, providing critical food, shelter, cover, nesting areas, and protection to between 4–6 million birds that visit each year. Impounded wetlands were created as part of the GSL ecosystem to support waterfowl habitat. These large, shallow, submergent wetlands are diked to control water levels to sustain aquatic plants which are an important food source. Besides providing critical habitat, these impoundments …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Much effort has been dedicated to expanding hydrological forecasting capabilities and improving understanding of the continental-scale hydrological modeling used to predict future hydrologic conditions and quantify consequences of climate change. In 2016, the National Oceanic and Atmospheric Administration’s (NOAA) Office of Water Prediction implemented the National Water Model (NWM) to provide nationally consistent, operational hydrologic forecasting capability across the continental U.S. The primary goal of this research was to develop hydrological tools that include modeling of flood inundation mapping and snowmelt contributions to river flow in snowmelt-dominated regions across the Western U.S. This dissertation first presents terrain analysis enhancements developed …

Thermodynamic Analysis Of A Novel Cycle For Nuclear Smr And Heat Transfer Performance Validation Of The Related Supercritical Working Fluids, Benjamin M. Pepper

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Currently, all operating nuclear power facilities in the U.S. follow the same general design and process: light-water reactors boil water into steam using bundles of nuclear fuel rods as a heat source, pumping that steam through a turbine which powers a generator to produce clean year-round electricity. Water is an effective coolant, but other facilities around the world have demonstrated the ability to use non-water-based coolants in nuclear reactor designs, which consequently have their own trade-offs. Some positive consequences of using different reactor designs include enhanced safety, better economics, and cheaper clean consumer energy. The work described in this paper …

Calibration Procedure For Dic Strain Measurements During Vibration-Based Fatigue Testing, Benjamin D. Hill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Vibration-based fatigue testing is fast and effective method for determining failure characteristics of a material. Often, a small electrical device called a strain gage is bonded to a rectangular plate specimen to measure the deformation of the plate during a test. However, these strain gages break before the plate does, so an alternative method would improve the results obtained from the test. As an alternative to strain gages, Digital Image Correlation (DIC) is a non-contacting, camera-based technique that measures the deformation of an object by comparing digital images taken before and after the object is deformed. During a vibration-based fatigue …

Advancing Data Collection, Management, And Analysis For Quantifying Residential Water Use Via Low Cost, Open Source, Smart Metering Infrastructure, Camilo J. Bastidas Pacheco

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Urbanization, climate change, aging infrastructure, and the cost of delivering water to residential customers make it vital that we achieve a higher efficiency in the management of urban water resources. Understanding how water is used at the household level is vital for this objective.Water meters measure water use for billing purposes, commonly at a monthly, or coarser temporal resolutions. This is insufficient to understand where water is used (i.e., the distribution of water use across different fixtures like toilets, showers, outdoor irrigation), when water is used (i.e., identifying peaks of consumption, instantaneous or at hourly, daily, weekly intervals), the efficiency …

Delivering On A Promise: A Longitudinal Cohort Study Of Emergent Bilinguals' Academic Achievement In A Utah Dual Language Program, J. Eric Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Emergent bilingual (EB) students are a growing population in the U.S. school system currently comprising over 10% of the total population. U.S. school districts have educated EB students using a myriad of practices, including dual language immersion (DLI). Many studies have looked at the academic achievement of native-Spanish speaking EB students, yet there is a dearth of research on DLI in medium-sized school districts in rural settings. This study focused on native-Spanish speaking EB students in a DLI program in a rural Utah district. Specifically, the study compared student academic achievement in English acquisition, English language arts, mathematics, and grade …

The Life Of Socrates: Plato, Xenophon, And The Untapped Potential Of The Socratic Problem, Abigail R. Fritz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary objectives of this thesis are to argue for an approach to the Socratic problem that (1) examines Xenophon’s Socratic writings along with those of Plato, and (2) analyzes the Socratic problem with a view to the ancient conception of philosophy as a way of life. To achieve these objectives, the introductory chapter provides an overview of scholarly approaches to the Socratic problem, which have tended to favor Plato as the only reliable source on the historical Socrates. This chapter argues that such approaches are flawed, and that both authors are important sources on the historical Socrates.

The second …

To answer this question, I examined transcripts from group interviews collected in the state of Texas. In total, there were 67 participants, many of whom were undocumented (n = 49) while the others had a relative or friend who was undocumented. Data were analyzed by looking for common patterns and themes in the transcripts, and guided by Critical Race Theory, Latine Critical Theory, and Undocumented Critical Theory. Results suggest that psychological distress is common …

Dynamic Contextualization Of Learners Within Educational Systems Through A Vygotskian Lens: A Telling Case Of Jesus Christ As An Educator, Nathan B. Meidell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study looked at Jesus Christ as a telling example of how transformative patterns of influence are exerted on learners by educators in educational systems. Based on concepts found in L.S. Vygotsky’s work, this study found these patterns acting as a current or stream of consistent aims and meanings introduced and reinforced by educators in the form of practices and methods that generated momentum toward/around desired learner responses. This study’s insights into these patterns of influence as employed by Christ during his ministry and as experienced by his learners provided new means of both interpreting their success and potentially replicating …

What Keeps Technology And Engineering Teachers In The Classroom? A National Mixed Methods Study, Cory J. Ortiz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Teacher retention is a significant issue impacting educational agencies around the country. Factors that have been found to be predictors of teacher retention include sense of belonging, sense of efficacy, and job satisfaction. Many personal and professional characteristics of a teacher also have been found to predict teacher retention. The purpose of this research was to explore how these factors predicted Technology and Engineering Educators' (TEE) teachers’ persistence to remain in the teaching profession. Furthermore, this research sought to identify programs that existed to help support TEE teachers in their persistence intentions.

This research found teacher job satisfaction was a …

Punishment And Choice, Rafaela M. Fontes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Punishment is defined as a consequence that decreases the frequency of behavior that produces it and is an important behavior regulation mechanism for learning to stop engaging in maladaptive behavior. Punishment has implications for behavioral disorders and treatments and plays an important role in both programmed and natural contingencies. Despite the clear relevance of punishment for behavioral regulation, little is known about how punishment works. Furthermore, punishment research has been in evident decline, leaving important empirical and theoretical gaps in the literature. Therefore, the overall goal of the present set of studies is to fill in some of these gaps. …

Assessing The Role Of Magnetite In Municipal Wastewater Treatment, Patricia Ayaa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Some municipal wastewater treatment (MWWT) facilities have adopted magnetite in their treatment processes through a technology called BioMag® to meet effluent regulatory requirements for total nitrogen and total phosphorus. However, there is limited information on the mechanisms and efficiency of magnetite in the removal of nitrogen (N) and phosphorus (P) from wastewater. This research, therefore, estimated its effectiveness in the removal of these nutrients, with a case study of the Marlay-Taylor Water Reclamation Facility in Maryland. The intervention analysis model was used, but a new forecasting approach to the model was proposed to fit the data in this study and …

Dynamical Systems Analysis In Adaptive And Metapopulation Ecology With Applications To Conservation Management, Guenchik Grosklos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The ability for a species to persist largely relies on how well they adapt to the environment and their interactions with local and global communities. Specifically, if adaptation occurs quickly enough or nearby communities sufficiently promote growth rates, populations at risk of extinction may persist. In this dissertation, we first develop a method that estimates and compares rates of change in time series data of population densities and measurable traits (phenotypes). Additionally, we compare between genetic (evolutionary) and non-genetic (plastic) trait change to determine whether phenotypes change faster when driven by evolutionary or plastic change. We then focus on metapopulation …
