Study Of Weight Gain In Freshman Students At The University Of Arkansas, Lily Maleknia
Study Of Weight Gain In Freshman Students At The University Of Arkansas, Lily Maleknia
Graduate Theses and Dissertations
This study was designed to examine the poor (non-nutritional) food choices that college freshman make when living on-campus and eating at on-campus dining facilities. These poor choices lead to excessive weight gain, eating disorders, declining health and wellness, and mental health issues (i.e. depression, anxiety, lack of self-confidence). These side effects can lead to a less than desirable 1st year college experience and lack of academic success. Based on these concerns, different investigations have been performed to determine the causes of this phenomena. Given adolescent weight gain is highly linked to being overweight and obesity in adults, a better understanding …

Open Source Intelligence For Cybersecurity Events Via Twitter Data, Dakota Dale
Open Source Intelligence For Cybersecurity Events Via Twitter Data, Dakota Dale
Graduate Theses and Dissertations
Open-Source Intelligence (OSINT) is largely regarded as a necessary component for cybersecurity intelligence gathering to secure network systems. With the advancement of artificial intelligence (AI) and increasing usage of social media, like Twitter, we have a unique opportunity to obtain and aggregate information from social media. In this study, we propose an AI-based scheme capable of automatically pulling information from Twitter, filtering out security-irrelevant tweets, performing natural language analysis to correlate the tweets about each cybersecurity event (e.g., a malware campaign), and validating the information. This scheme has many applications, such as providing a means for security operators to gain …

Social Capital And Academic Achievement In Arkansas, Misty D. Newcomb
Graduate Theses and Dissertations
The purpose of this study is to demonstrate a more comprehensive understanding of the impact that a child’s broader context has upon his or her academic outcomes, and presumably, life. Using Bronfenbrenner’s theory of human development, this study examines the extent to which social capital and student achievement are correlated and whether an infusion of funding for schools that presumably lack social and economic capital might predict academic achievement in schools from economically depressed regions. Findings indicate that some aspects of social capital and funding initiatives have a demonstrated impact on student achievement but there is not a correlation with …

Green Infrastructure In The Ozarks: Northwest Arkansas Development Policy And The Open Space Plan, Daniel Holtmeyer
Graduate Theses and Dissertations
Northwest Arkansas regional planning authorities in 2016 released the Northwest Arkansas Open Space Plan, a voluntary document outlining ways to protect and preserve important open spaces even as the region’s population balloons and urban development spreads outward. No one appears to have made a systematic attempt to gauge the Plan’s impact on development decisions, however. In this thesis, I conduct a qualitative survey of several cities and counties’ planning codes and comprehensive plans to determine how much these policies have in common with the Open Space Plan’s essential principles. From that survey, I also conduct two case studies of recent …

Achieving Causal Fairness In Recommendation, Wen Huang
Achieving Causal Fairness In Recommendation, Wen Huang
Graduate Theses and Dissertations
Recommender systems provide personalized services for users seeking information and play an increasingly important role in online applications. While most research papers focus on inventing machine learning algorithms to fit user behavior data and maximizing predictive performance in recommendation, it is also very important to develop fairness-aware machine learning algorithms such that the decisions made by them are not only accurate but also meet desired fairness requirements. In personalized recommendation, although there are many works focusing on fairness and discrimination, how to achieve user-side fairness in bandit recommendation from a causal perspective still remains a challenging task. Besides, the deployed …

Polymeric Biomaterials Approaches For Engineering The In Vitro Cellular Microenvironment For Mscs, Mahsa Letter-Mahsa Haseli
Graduate Theses and Dissertations
Cell therapy is a technology that relies on replacing diseased or dysfunctional cells with healthy functioning ones. One of the cells used for such advanced therapies are stem cells, owing to their ability to differentiate into specific cells required for repairing damaged or defective tissues or cells. The majority of cell-based products are intended to transiently persist in the patient, secreting factors which then allow the patient’s body to heal; in these products, the cells are subsequently eliminated from the body. Furthermore, unique manufacturing platforms, in addition to novel commercialization strategies, will be required to create a successful, sustainable cell …
Political Speech: The Influence Of Speaker Sex And Verbal Aggression On Message Perception, Amanda Magusiak
Political Speech: The Influence Of Speaker Sex And Verbal Aggression On Message Perception, Amanda Magusiak
Graduate Theses and Dissertations
This study examined political messaging. More specifically, I considered the influence of the sex of the speaker and the use of verbal aggression on overall message perception. One hundred and six college-aged students read eight excerpts of political speech where sex of the speaker (male; female) and level of aggression (aggressive; nonaggressive) were manipulated. Participants then completed measures assessing their agreement with the political message, the speaker’s credibility, the speaker’s communicative appropriateness, and the speaker’s level of verbal aggressiveness. Results indicated that male and female political speakers were evaluated similarly on measures of agreeableness, credibility, and appropriateness. In addition, aggressive …

Potential Control Of Invasive Mesquite Through Improving The Consumer’S Understanding Of Liquid Smoke Applications., Seth W. Ellsworth
Graduate Theses and Dissertations
Mesquite trees continue to invade forests and range lands in many countries across the world. The cost to remove these trees is staggering. In Texas, landowners spent $25 million over a 10- year period to clear 300,000 ha of mesquite trees, a fraction of the 22 million ha of Texas land affected by this invasion. Estimates are that the mesquite continues to negatively impact one to two percent of additional land in selected counties each year in Texas. However, the problem is not unique to Texas, but rather to the 44 species of mesquite trees, belonging to the genus Prosopis …

Experienced Nonnative English-Speaking Teachers’ Nonnativeness-Related Challenges, Coping Strategies, And Identity Construction, Roseli Marqueti Matos Franco
Graduate Theses and Dissertations
Kamhi-Stein (1999) declares that little is known about nonnative English-speaking teachers (NNEST) who work in ESL settings also known as Inner Circle countries. Twenty years later, Fan and de Jong (2019) have echoed that view by stating that traditionally research on NNESTs focuses on Teaching English to Speakers of Other Languages (TESOL) international graduate students and that little is known about professional nonnative English-speaking teachers in English-dominant environments such as the U.S.A. Therefore, to try to help fill this gap in the literature, I investigated the lived experiences of English teachers who speak English as an additional language, often called …

I utilize Discourse Analysis to contextualize lyrics, music, and music videos that resist hegemonic notions of italianità and champion inclusive citizenship. Artists analyzed include Amir Issaa, Karima DueG, Ghali, Tommy Kuti, Cécile, Chadia Rodriguez, and Alessandro Mahmoud. Centralizing hip hop as a collective site of resistance demonstrates the movement towards recognition as well as equal representation. Second generation artistry and lyricism starts …
The Student-Teacher Romance Film Genre: Hollywood's Historical Representation Of Abuse Of Power, Darby Gilliland
The Student-Teacher Romance Film Genre: Hollywood's Historical Representation Of Abuse Of Power, Darby Gilliland
Graduate Theses and Dissertations
Despite vast literature analyzing films that depict romantic and sexual relationships between young students and their teachers, scholarship has yet to explicitly call this category of films and television a genre. The purpose of the present thesis is to define the student-teacher romance film genre and identify patterns that make it up as a means of illuminating the genre’s exploration of abuse of power in the classroom. I use a historical-generic methodology and gaze theory as a framework to conduct this analysis. I identify three distinct eras of the genre and analyze films from each time period. The first era …

In-Situ Tribology Of Engineered Surfaces With 3d-Printed Micro/Nano-Textures, Mahyar Afshar Mohajer
Graduate Theses and Dissertations
Surface texturing is an effective way to reduce the adhesion and friction between two contacting surfaces by reducing the real area of contact between them, providing a potential solution for adhesion and friction-induced failures, for example, failures in micro-/nano-electromechanical systems (MEMS/NEMS). Surface texturing is also essential to the realization of functional surfaces such as superhydrophobic/philic and icephobic surfaces. However, textures are prone to deformation due to being subjected to higher contact pressures. The advancement of 3D nanoprinting by two-photon lithography (TPL), combined with the ability to make an in-situ observation of the interplay between the forces and the sliding surfaces …
Dream Border, Pardis Ahmadpour Mobarake
Dream Border, Pardis Ahmadpour Mobarake
Graduate Theses and Dissertations
Dream Border is the result of my lived experience of relocation. The exhibition addresses the duality of being on the border between reality and imagination. In this place, the present, past, and future exist simultaneously. By engaging with personal narratives, childhood memories, as well as Iranian cultural and literary visual elements, I search for universal concepts in relocation. These works evoke the imposition of power and the many phenomena that the contemporary world endures despite globalization, such as anxiety, fear, and oppression on a small or large scale, which compel people to relocate. Uncertainty in the process of migration and …

Evaluation Of Biological And Chemical Seed Treatments For Management Of Rice Diseases, Sherif Adam Sharfadine
Graduate Theses and Dissertations
Rice is the primary staple for more than half of the global population and is the second most important cereal worldwide. In the US, rice is primarily grown in the southern states, with Arkansas leading production and responsible for 47% of the total rice production in the country. Diseases cause significant yield losses in rice. Sheath blight, rice blast and bacterial panicle blight are the main diseases in rice and cause significant yield losses. Sheath blight alone could cause up 50% yield loss in heavily damaged fields with highly susceptible cultivars. Additionally, rice seed and seedling diseases primarily caused by …
Improving Building Cfd Peak Pressure Computation Using Les With A Focus On Inflow Turbulence Methods And Grid Spacing Size., Zahra Mansouri
Improving Building Cfd Peak Pressure Computation Using Les With A Focus On Inflow Turbulence Methods And Grid Spacing Size., Zahra Mansouri
Graduate Theses and Dissertations
Structural failures by extreme winds often leads to economic losses and even deaths. Proper design of buildings requires accurate estimation of wind loads to prevent structural damage. Using routine guidelines generally leads to the underestimation of buildings’ peak pressures, in which most failures occur. To estimate wind loads more accurately three different methods (i.e., field measurement, wind tunnel (WT), and computational fluid dynamics (CFD)) are in use. A well-validated CFD provides more flow field details at lower costs compared to field measurements and WT. As strong winds are extremely turbulent, the effects of turbulence in wind should be incorporated into …
Using Reinforcement Learning To Improve Network Reliability Through Optimal Resource Allocation, Henley Wells
Using Reinforcement Learning To Improve Network Reliability Through Optimal Resource Allocation, Henley Wells
Graduate Theses and Dissertations
Networks provide a variety of critical services to society (e.g. power grid, telecommunication, water, transportation) but are prone to disruption. With this motivation, we study a sequential decision problem in which an initial network is improved over time (e.g., by adding or increasing the reliability of edges) and rewards are gained over time as a function of the network’s all-terminal reliability. The actions during each time period are limited due to availability of resources such as time, money, or labor. To solve this problem, we utilized a Deep Reinforcement Learning (DRL) approach implemented within OpenAI-Gym using Stable Baselines. A Proximal …
A Case Study Examining Women In Leadership At A College Of Osteopathic Medicine, Sloane Gibson Kelley
A Case Study Examining Women In Leadership At A College Of Osteopathic Medicine, Sloane Gibson Kelley
Graduate Theses and Dissertations
Dr. Andrew Taylor Still, the founder of osteopathic medicine, actively promoted gender parity in the field from its inception, at a time when few medical schools accepted women into their programs, and even fewer all-female medical schools existed (Quinn, 2017; Simpson & Weiser, 1996). Although an almost equal number of male and female students are enrolled in osteopathic medical schools, men far outnumber women in positions of leadership. While the data for the number of women deans and department chairs at osteopathic medical schools does not exist, research by the Association of American Medical Colleges (2021) showed that 24% of …

Enhancing Human Schwann Cells Reparative Behavior Using Heparin/Collagen Layer-By-Layer Coatings, Luis Carlos Pinzon-Herrera
Enhancing Human Schwann Cells Reparative Behavior Using Heparin/Collagen Layer-By-Layer Coatings, Luis Carlos Pinzon-Herrera
Graduate Theses and Dissertations
When a peripheral nerve injury (PNI) occurs, the gold standard for tissue regeneration is the use of autografts. However, due to the secondary effects produced by multiple surgeries involved in the removal and implantation of autografts for very small lesions, it is possible to replace them with the use of Nerve Guide Conduits (NGCs). However, NGCs are limited to short lesions (less than 1 cm). This limitation is caused by the absence of compounds in the extracellular matrix (ECM) that autografts can provide. Since much of the regenerative process takes place on the NGC surface, our work aims to modify …
