Motives For (In)Effective Giving: Comparing Rural And Urban Groups In South Africa., Luvuyo Bulelani Magwaza

Master's Theses

Different cultures have their own set of norms and values that not only shape people’s motives but also influences their decision making. What may be viewed as logical and ethical in one culture, may be seen as illogical or unethical in another. One area that is consistently affected by cross-cultural differences in motives is charitable giving. Recently, there has been an increase in interest around effective altruism— a social movement and philosophy that argues, people should give to charities that do the most good. Prior research that has found that people do not give based on efficiency; instead, people give …

Finding Balance: A Content Analysis Of How Newspaper Authors Framed Simone Biles Before, During, And After The 2020 Olympic Games, Hadley Howell

Master's Theses

Simone Biles was considered the GOAT, Greatest of All Time, going into the 2020 Olympic Games. However, after the COVID-19 pandemic, the Larry Nassar trial, and the weight of the world on her shoulders, Biles would withdraw from the women’s gymnastics team final competition for mental health reasons. Thus, the following study examines how Biles was framed in the ten most circulated newspapers in the United States before, during, and after the 2020 Olympic Games. Results show that an author’s race and gender, topic of the article, type of article, and if an article contained an image or not ultimately …

In some cases, researchers also have explored the complicated …

How A Book Changed A Nation [2022], Teodora Buzea

Master's Theses

“We don’t believe in vampires.”

I didn’t bother to turn away from the TV to look at my parents. On screen, a crew of young men were interviewing an old woman. She spoke only Romanian, and a too-perfect female voice spoke for her in English. I could see the confident fear in her expression as she exclaimed that vampires were indeed real and that she was always scared of them. She wasn’t alone. All of Transylvania were aware of the existence of vampires. Truly, these young men— ghost hunters and cryptologists—were right to come here to this haunted nation. The …

From Mesoamerica To Aleppo And Transylvania: The Global Migration Of The Chile Pepper, Arianne M. Peterson, Arianne Peterson

Master's Theses

This thesis explores the migration of the chile pepper, or capsicum anuum, from Mesoamerica into the Old World after 1500, focusing on two case studies of the Aleppo pepper in Syria and paprika in what was once Hungarian Nagyvarad, and which is now Romanian Oradea. Using foodways as a historical lens, and considering the movement of food as historical, it can be seen that the chile pepper, despite its low profit value, illustrates a globalization that existed well before modern times, and it came to cement itself within many different cultures as a symbol of identity. Despite its far-away …

The Rise Of Terrorism In Africa And What It Means For U.S. Policymakers, Bridget Mary Hughes

Master's Theses

This thesis utilizes three case studies to measure the rise of terrorism in Africa. This qualitative data leads the reader to one ultimate question: what does the rise in terrorism in Africa mean for the United States (U.S.) and U.S. policymakers, National Security academia, students in National Security, if anything at all? The answer is: if civilian and military compounds are being targeted by these violent extremists, as these three case studies demonstrate, it is my recommendation that U.S. policymakers cease sending troops to the African theater and, instead, allocate funding to the citizens and nonprofits of the countries whom …

Stability Of Universal Screening Over Time: An Examination Of The Student Risk Screening Scale, Rebecca Wagner Lovelace

Master's Theses

Universal screening is a proactive method to identify students that are at risk for social-emotional and behavior (SEB) problems and provide information to schools to support early intervention for at risk children. Current recommendations for practice indicate screening should be conducted at three time points during the school year. Previous studies suggest that this recommendation is not empirically based and fewer screenings per year may be sufficient for identifying students at risk. The current study seeks to extend the literature regarding the stability and consistency of screening scores over time by analyzing ratings from the Student Risk Screening Scale (SRSS) …

Drinking Motives As Mediators For The Relationships Between Overparenting And Alcohol Outcomes, Tatum Freeman

Master's Theses

The present study investigated the mediating role of drinking motives in the relationship between overparenting and alcohol outcomes using a sample of 207 traditional age college students (i.e., 18-25 years old; M = 19.8, SD = 1.64). Data on participant demographics, drinking motives, the practices of participants’ primary caregiver, typical weekly drinking, hazardous drinking, and alcohol consequences were collected via SONA (an online participant management software that allows researchers to collect data from a university psychology subject pool). Participants were 89.4% female and 54.1% White. Coping and conformity drinking motives partially mediated the relationships between overparenting, alcohol consequences, and hazardous …

Cdc’S Covid-19 Vaccination Messages And Public Engagement: A Study On Facebook Posts, Hasan Mahmud Faisal

Master's Theses

Government health agencies utilize social media for public health interventions. This study examines how CDC, the national public health agency of the United States, use Facebook to disseminate COVID-19 vaccine messages and to get public engagement towards them over the past two years (2020-2022). Investigating the process of dialogic potentials of Facebook from the dialogic theory of public relations perspective, the current study analyzes 681 posts and 3,405 comments from CDC’s official Facebook page.

How Chicago Public Schools Engaged African American Parents In The Closing Of Austin Career Academy High School, Shani Blackwell

Master's Theses

The role of African American parents in education reform initiatives in Chicago is not clearly defined. Local School Councils (LSC) allow parents to make school related decisions in Chicago. But LSCs are removed from decisions about whether or not to place school on or off probation, and whether or not to close schools based on performance or building utilization. In 2013, African American and Latinx parents expressed outrage over the decision by Chicago Public Schools (CPS) to close 49 schools with protests, including a hunger strike by a group of parents, and pleas to the Chicago Board of Education (BOE). …

Constructing Planetary Citizens Through Ecopedagogy In U.S. Social Studies Standards, Madeline Anne Rainey

Master's Theses

The world is in the age of the Anthropocene, where humans are impacting the environment to disastrous effects. The capitalist economy, promoting neoliberal policies of mass consumption, has exacerbated the world's environmental deterioration and social inequity. The rights and responsibilities people hold have been rapidly changing with the fourth industrial revolution. Globalization and Information and Communications Technology (ICT) have further expanded notions of citizenship. While there have been numerous attempts to bring the environment into schools, it has not emphasized what this crisis deserves. Ecopedagogy, as a critical theory, explicitly examines the interplay between environmental and social problems and challenges …

Taking It Too Far? Examining Derogation In Sexism Confrontations, Bayleigh Smith

Master's Theses

Sexism continues to be prevalent within today’s society (Bates, 2012; Crandall et al., 2018; World Health Organization, 2021), creating the need for methods to respond to such bias. Confrontation is one method that allows targets of sexism to stand up for themselves (Haslett & Lipman, 1997; Hyers, 2007; Kaiser & Miller, 2004), but often comes with social costs (e.g., being disliked, Czopp & Monteith, 2003; Dodd et al., 2001; Gulker et al., 2013; Kaiser & Miller, 2001). However, researchers have not dissected the factors that affect the social costs associated with confrontation (i.e., being labeled as a “sexist”, humor, or …

Interrogating Antagonistic Differences Among Pseudomonas Aeruginosa Cdia Alleles, Haotian Yang

Master's Theses

Bacteria are complex social organisms that live within mixed communities where microorganisms compete for limited resources. We studied Contact-Dependent Growth Inhibition (CDI), a particular type of competition mediated by a type 5b, or two-partner, secretion system that is widely spread among Gram-negative bacteria. CdiB and CdiA make up the two-partner secretion system that mediates CDI. CdiB translocates CdiA to the cell surface, and CdiA delivers its C-terminal toxin domain to the target cell. The C-terminal toxin (Tox) domain of CdiA is highly diverse. We studied Tox domains of various Pseudomonas aeruginosa clinical isolates. We found different strains that contain unique …

Role Of Tetraspanins In Sars-Cov-2 Fusion And Entry, Marcos Saul Santiago Figueroa

Master's Theses

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the pandemic the world has been facing in recent years. Even as new countermeasures are developed, there is still much we don’t know in terms of its entry into host cells. Tetraspanins are transmembrane proteins that are near ubiquitous amongst cell types. They fulfill numerous roles, including that of a viral co-receptor. Here, we considered whether tetraspanins, specifically CD9, CD63, and CD81 influence SARS-CoV-2 fusion and entry. Using ACE2-LgBit and tetraspanin overexpressing EVs and HeLa cells, we find that the presence of excess tetraspanins inhibit fusion and entry. However, we …

Analysis Of Current And Future Flood Hazard In The Sacramento-San Joaquin Delta, Nicholas L. Mcguire

Master's Theses

The primary motivation of this study is to estimate the current and future flood hazard throughout the Sacramento-San Joaquin Delta in the context of sea-level rise. I also analyzed the effects of storm surge and river flow on extreme events to better understand how these events originate and vary spatially and in time. To address this goal, I combined digital water level records (primarily 1983-present) with archival data collected by the California Department of Water Resources (1929-1983) to reevaluate flood hazard in the Delta and investigate the possible sensitivity of the region different sea-level rise projections. Available archival records from …

Thermodynamic And Structural Quantification Of Metal Ions Binding To The Antimicrobial Peptide Calcitermin, Sohee Choi

Master's Theses

Over the past several decades the number of antibiotic resistant bacteria has grown dramatically, in part due to the over-prescription of antibiotics. This rise in antibiotic resistance has led to development of novel antibiotics. An attractive alternative to treat bacterial infections may be the use of antimicrobial peptides due their little-known resistance from bacteria. One such peptide is calcitermin (VAIALKAAHYHTHKE), a 15-residue peptide found in human airways. Calcitermin has antimicrobial properties that target Gram-positive bacteria and is most active in acidic buffer (pH 5.4) due to protonation of its three histidine residues, which allows it to interact with the negatively …

Ncaa Di Assistant Coaches' Understanding Of Mental Performance And Mental Health Services, Heather Hill

Master's Theses

The National Collegiate Athletic Association (NCAA) has acknowledged the importance of providing student-athletes with psychological services throughout their athletic careers (NCAA, n.d.). Two vital services for student-athletes are mental performance services that are focused on sport-related issues and mental health services that are centered around personal issues (Sudano & Miles, 2017). Previous literature around mental performance and mental health services has not distinguished between them, making it difficult to understand key stakeholders’ perceptions and knowledge of both mental performance and mental health services. Assistant coaches play an important role in NCAA athletic departments and spend substantial amounts of time connecting …

Investigation Of Dead Ocean Quahogs (Arctica Islandica) Shells On The Mid-Atlantic Bight Continental Shelf, Alyssa Leclaire

Master's Theses

Ocean quahogs, Arctica islandica, are a long-lived, widely dispersed, biomass dominate in the Mid-Atlantic; therefore, quahog shells are valuable resources for studying climate change over time. Recently, dead ocean quahog shells were discovered south and inshore of the present biogeographic range of this animal. The presence of ocean quahog shells outside the current range is presumably a consequence of past regressions and transgressions of the Cold Pool, the bottom-trapped, cool body of water that allows boreal animals to live at lower latitudes. Dead ocean quahog shells were collected offshore of the DelMarVa Peninsula then radiocarbon-dated, evaluated for taphonomic condition, …

Pressure Disturbance Upstream Of The Boundary Layer Data System, Michelle S. Leclere

Master's Theses

The primary objective for this work was to evaluate the reliability of computational fluid dynamics (CFD) tools in the prediction of upstream surface pressure disturbance and pressure drag of various instrument excrescence shapes for a small aircraft flight test device called the Boundary Layer Data System (BLDS). Insights on pressure disturbance will serve as a guide for the placement of BLDS probes/sensors, and pressure drag can be used to ensure sufficient adhesive is used to install BLDS instrumentation. The Mach number for all CFD cases was 0.12 and the Reynolds number based on excrescence height varied from 4 x 10 …

"Conserving" The Middle Ground: Tennessee's Unionist Press In The Secession Crisis, 1860-1861, Michael Singleton

Master's Theses

This thesis advances scholars’ understanding of how newspaper editors framed and presented news during the secession crisis of 1860-1861. Methodologically, it draws on the publications of seven Unionist editors from Tennessee who initially resisted secession but later pursued different courses during the Civil War. Through this period, editors balanced their roles as journalists and political actors working to advance an ideological cause. Guided by existing practices and their unique journalistic styles, these editors presented a near unified message—influenced by Whig political culture—that framed their response to outside events. This unanimity fractured in 1861 as local pressures, business interests, and personal …

Psychosocial Maturity And Alcohol Outcomes: The Mediating Role Of Alcohol Protective Behavioral Strategies, Skyler Hoover

Master's Theses

The present study evaluated the mediating role of alcohol protective behavioral strategies on the relationship between temperance, responsibility, perspective (i.e., the facets of psychosocial maturity) and alcohol use outcomes. Potential invariant paths among graduate and undergraduate students were also explored. All participants were undergraduate and graduate students at the University of Southern Mississippi aged 18 to 25. Participants reported demographic information and completed measures of temperance, responsibility, perspective, alcohol use, and alcohol consequences. Results indicated the full mediation model showed poor fit the data; greater temperance predicted greater alcohol protective behavioral strategy use, greater responsibility and perspective predicted less alcohol …

Artist-Configurable Node-Based Approach To Generate Procedural Brush Stroke Textures For Digital Painting, Keavon Chambers

Master's Theses

Digital painting is the field of software designed to provide artists a virtual medium to emulate the experience and results of physical drawing. Several hardware and software components come together to form a whole workflow, ranging from the physical input devices, to the stroking process, to the texture content authorship. This thesis explores an artist-friendly approach to synthesize the textures that give life to digital brush strokes.

Most painting software provides a limited library of predefined brush textures. They aim to offer styles approximating physical media like paintbrushes, pencils, markers, and airbrushes. Often these are static bitmap textures that are …

Specialized Named Entity Recognition For Breast Cancer Subtyping, Griffith Scheyer Hawblitzel

Master's Theses

The amount of data and analysis being published and archived in the biomedical research community is more than can feasibly be sifted through manually, which limits the information an individual or small group can synthesize and integrate into their own research. This presents an opportunity for using automated methods, including Natural Language Processing (NLP), to extract important information from text on various topics. Named Entity Recognition (NER), is one way to automate knowledge extraction of raw text. NER is defined as the task of identifying named entities from text using labels such as people, dates, locations, diseases, and proteins. There …
