When Engagement Meets Distraction: The Effects Of Multitasking Types On Learning From Video Lectures, Zubeiru Mahama

Arts & Sciences Graduate Student Theses and Dissertations

Students often multitask with lecture-relevant (e.g., note-taking) and lecture-irrelevant (e.g., texting) secondary tasks during lectures and such behavior tends to be more common in asynchronous than synchronous settings. Two experiments investigated the combined and comparative effects of lecture-relevant and lecture-irrelevant secondary tasks on attention to and retention of a geology video lecture in a simulated asynchronous setting. Participants were randomly assigned to one of four conditions: lecture-only, lecture-relevant multitasking (i.e., taking notes during the lecture), lecture-irrelevant multitasking (i.e., completing a survey in Experiment 1 or instant messaging in Experiment 2 during the lecture), or hybrid multitasking (both note-taking and survey …

Exploring The Relationship Between Adhd, Mood Disorders, And Motivation Among Women Studying For The Ged: A Preregistered Study, Amanda Dawn Kennedy

Graduate Theses and Dissertations

Adult women with Attention Deficit Hyperactivity Disorder (ADHD) and mood disorders, such as anxiety and depression, represent an understudied and underserved demographic within educational research, particularly among those pursuing nontraditional academic pathways, such as obtaining the high school equivalency diploma (i.e., GED). Despite the well-documented challenges associated with ADHD and mood disorders, including difficulties with motivation, executive functioning, and emotional regulation, little research has examined how these factors influence women’s persistence and success in adult education settings. Understanding the unique experiences of this population is essential for developing targeted support systems that enhance learning outcomes and academic achievement. This study …

The Upcoming Moral Crisis In Primitive Artificial Intelligence, Justin E. Edens

Graduate Theses and Dissertations

As we continue to develop artificially intelligent systems, there is an increasingly high chance that we will develop a system that is both conscious and capable of suffering. Furthermore, it is likely that the development of this conscious machine will be entirely unintentional. While this machine will have moral status, identifying it will be extremely difficult, leading to it being treated the same as its inert predecessors. For these reasons I believe that a crisis in ethics is looming. This paper aims to argue that it is possible for a machine to have moral status, that the first such machine …

Resilience Redefined: Exploring The Impact Of Childhood Trauma On The Value Systems Of High-Achieving Corporate Men, Lana B. Henry

Graduate Theses and Dissertations

This qualitative study employed Interpretive Phenomenological Analysis (IPA) to explore how childhood trauma influences the value systems of high-achieving corporate men. In contemporary corporate culture, where stoicism, performance, and independence are often rewarded, little attention is paid to how early adversity informs internal frameworks of meaning, leadership, and success. Semi-structured interviews were conducted with six high-achieving men, all executives and leaders in high-performing industries, who self-identified as having experienced childhood trauma. Data were analyzed using a six-step IPA process and interpreted through the lens of Schwartz’s Theory of Basic Human Values and social constructivism. Findings revealed that childhood trauma deeply …

Assessment Of Mental Health Needs For Chronically Unhoused Individuals Living In A Bridge Housing Community, Isabel Furse Augur

Graduate Theses and Dissertations

Higher rates of psychopathology and substance use are reported in individuals experiencing homelessness compared to the general population, especially in those who are chronically unhoused. Chronically homeless individuals are also less likely to access treatment for these problems because of barriers to care. Addressing housing needs is an important first step in engaging people who are homeless with the care they need. This project focused on assessing the mental health needs of a Housing First community in Northwest Arkansas, which has few barriers for entry but does not provide direct support for mental health. This project adopted a community-based participatory …

End Times: American Mortality, Death Materiality, And Social Death In The 1990s, Jordan A. Savage

Graduate Theses and Dissertations

The United States in the 1990s was marked by pervasive representations of death in popular culture. As death imagery became increasingly visible in entertainment, there was a growing detachment from the embodied, biological realities of death, a tension intensified by the ongoing AIDS crisis. This project explores how death is politicized and how decisions about who lives and dies are shaped by power. I draw on a constellation of theoretical frameworks that collectively illuminate the operations of state-sanctioned death and social abandonment. These include Michel Foucault’s concept of biopolitics, which examines the management of life by state power; Giorgio Agamben’s …

The Black Bombers Of Ghana: Sport, Nation-Building And Pan-Africanism, 1958 To The 21st Century, Kenneth Tagoe

Graduate Theses and Dissertations

Ghana’s Amateur Boxing Team, known as the Black Bombers, has impacted the country’s political and socio-economic development since its formation in 1958. This thesis argues that amateur boxing was one of the sports that Kwame Nkrumah, Ghana’s first president, used to promote nation-building and, more broadly, a Pan-African agenda. The team’s success in international competitions has widely projected Ghana's sporting reputation and reinforced the Pan-African principles of Black pride and excellence in the global athletics arena, and beyond. This thesis traces the origins of amateur boxing and the formation of the Black Bombers, the squad’s participation in international athletics events …

Having a scientifically literate citizenry is an asset nationally and globally, and knowledge of the nature of science (NOS) is a crucial element in such literacy. Science teachers are a vital link if students are to understand key elements of the NOS, yet teachers themselves often lack knowledge of NOS and how to integrate NOS content into science lessons. Investigating the impact of a series of inservice professional development experiences using three distinct delivery modes (face-to-face, hybrid, online) for teachers in my home country of Bhutan is the overarching goal of the study reported here. The study used a mixed-methods …

Classifying Advanced Persistent Threat Stages And Techniques Via Graph-Enhanced Network Flow Representations, Md Taef Uddin Nadim

Graduate Theses and Dissertations

Advanced Persistent Threats (APTs) are complex, stealthy attacks that involve multiple stages and many attack techniques used in each stage, making them difficult to defend against. Although many solutions can detect APTs, most of them only detect the existence of attack, but cannot produce fine-grained classification over the stage of the APT and the specific attack technique used. Some existing solutions can classify the stages of APT, but few of them provide attack technique classification, and existing work do not provide interpretability for the classification or countermeasures for the attack. In this thesis work, we propose a solution named CAPTure, …

The Bacteria Who Lived: Uncovering And Mitigating The Persistence Of Pathogens In Low-Moisture Food Processing, Kavita Shripati Patil

The Effects Of Background Child-Directed And Adult-Directed Singing On Reading Comprehension Performance, Agnes Yeboah Amfo-Adu

Graduate Theses and Dissertations

Although music features in speech, such as those found in child-directed speech and song, are known to enhance language processing, the underlying mechanism of this benefit remains unclear. Prior research has primarily compared verbal materials presented in a musical, child-directed style to those in a less musical, adult-directed style, leaving it uncertain whether the benefit stems from the music style of verbal presentation or mere exposure to musical features. This study examined whether the language benefits of child-directed input persist when it is presented as background auditory stimuli rather than the primary focus of cognitive tasks. Experiment 1 found that …

Structure, Thermodynamics, And Dynamics Of Acetonitrile In Titan-Like Conditions, Sagar Chandra Roy

Graduate Theses and Dissertations

Titan is one of the most interesting satellites in the solar system. It is the only other place in the solar system containing stable deposits of liquid and a hydrological cycle other than earth. The abundant existence of N2 and CH4 in Titan’s atmosphere makes nitrile formation highly likely both in the atmosphere and surface. Infrared spectrometer data from Voyager 1 expedition revealed the presence of acetonitrile (CH3CN) in the atmosphere along with several other nitriles such as hydrogen cyanide (HCN) and cyanoacetylene (HC3N). According to theoretical models nitrile formation is caused by photodisscociation of nitrogen in the tholin haze …

Regulating Cutthroat Business, Luke Herrine

Articles

The production of meat is almost entirely controlled by a small group of multinational agribusinesses. These "packers" own everything from animal genetics to feed to wholesaling to slaughtering to butchering-leaving only the raising of the animals to nominally independent farmers, who are, in turn, controlled through one-sided contracts. Packers use this power both to push down costs and make raising and slaughtering animals more specialized and efficient and to extract more money from farmers, workers, retailers, consumers, and state and local governments. They also wield their resources to avoid accountability for the costs they impose on others and to shape …

An Examination Of Legal Status, Law Enforcement Perception, And Crime Victimization And Reporting Among Hispanic Immigrants, Guadalupe C. Cabrera

Electronic Theses and Dissertations

This study relied on in-depth interviews with naturalized citizens and lawful permanent resident Hispanic immigrants to explore their perceptions of law enforcement and experiences with crime victimization and reporting. Past literature has explained that the absence of legal status may deter crime reporting. We added to this body of work by investigating relationships among legal status, trust, and reporting behaviors. This study finds that direct experiences with law enforcement and acquired knowledge may be a better indicator of law enforcement trust and crime reporting compared to legal status. While most participants expressed trust in law enforcement, others felt neutral due …
