Predicting Social Media Addiction: The Influence Of Paralinguistic Digital Affordances And Cognitive Processes On Social Media Use, Dakota Krebs

Theses and Dissertations

Social media has become an increasing staple in everyday life for numerous people. Yet, excessive and repetitive social media usage may become problematic, to the extent that the behavior takes the form of a psychological addiction. The primary objective of this study was to explore prospective factors that could predict the psychological dependency on social media applications, characterized as social media addiction (SMA). Paralinguistic Digital Affordances (PDAs) are “likes” one receives on social media and may predict SMA via the expected gratification attained when a PDA is received. Cognitive processes, assessed with a general executive functioning index and the n-back …

Measuring The Clinical Effectiveness Of Telenutrition Medical Nutrition Therapy Among American Indian And Alaska Native Adults Newly Diagnosed With Type 2 Diabetes, Charisse Lindsey Holiday

Theses and Dissertations

The COVID-19 global pandemic was the impetus of the transition from in-person medical nutrition therapy (MNT) visits to telephone MNT. This occurred without evaluation of its clinical effectiveness, especially for American Indians and Alaska Natives (AI/AN). It is known that in-person MNT is clinically effective at lowering hemoglobin A1c (A1c) and that people with diabetes who experience food insecurity have poorer health. However, research characterizing food insecurity among AI/ANs is limited. This retrospective observational analytical study was conducted at the Phoenix Indian Medical Center (PIMC) in Phoenix, Arizona to assess the clinical effectiveness of telephone delivered MNT services by a …

Scaling Laws For Diffusion In Crystallized Plasma From Molecular Dynamics, Dany Yaacoub

Theses and Dissertations

Diffusion coefficients for crystallized Coulomb plasmas are essential microphysics input for modeling white dwarf cores and neutron star crusts. Solving for diffusion coefficients require running large molecular dynamics simulations with thousands of particles over millions of timesteps. The diffusion in a crystallized plasma has been largely ignored and is often taken to be zero in stellar evolution codes. We find that not only is this incorrect, but we find that the diffusion in a crystallized plasma can be modeled completely using a universal scaling law independent of screening. Our simulations also show that the dominant mode of diffusion in a …

Nutrient Transport And Transformation In Anaerobic Co-Digestion Of Crop Residues And Swine Manure, Shelby Stoner

Theses and Dissertations

Cover crops may improve soil quality, water quality, soil health, reduce soil fertilizer use, and increase nutrient availability to cash crops. The benefits of cover crops are discussed due to the below ground presence of cover crops, but the aboveground biomass can serve as a source of sustainable energy through anerobic digestion. The nutrients in the above ground biomass can also be recycled and reused through land application of digestion effluent. We have tested anaerobic co-digestion of different biomass feedstocks: cover crops, soybean stalk, and corn stover with swine manure using both small and pilot scale digesters. Nutrients, specifically NPK, …

Using a qualitative approach, data were collected through ten semi-structured interviews with Slovakian immigrants within the greater Chicago area. The informants in this study recalled their reasons for leaving Slovakia, which …

How I Came To Understand What Art Was, Ilse Miller

Theses and Dissertations

This thesis explores my multidisciplinary art practice through three specific types of work: mobiles, books, and boxes. Each type of artwork functions as a vessel used to preserve objects and fleeting moments. Rooted in Anna Kornbluth's "aesthetic regime of immediacy," the work balances preservation with loss and intuition with craft. Inspired by Rauschenberg and Abercrombie, it challenges artistic boundaries by using immediate, everyday materials. These mobiles, books, and boxes become conduits for memory and invite viewers to connect personal and collective experiences.

Theses and Dissertations

This dissertation provides a methodological framework that seeks to further scholarly and pedagogical inquiry at the intersections of feminist rhetorical studies, digital rhetoric, and cultural studies. More specifically, drawing upon theories of technofeminism (relationships among technology and feminism) and cyberfeminism (relationships among the internet and feminism), this dissertation proposes a digital technofeminist methodology to study the complex relationships between virtual, augmented, and mixed reality technologies, bodies, and rhetoric. This framework aims to help digital rhetoric scholar-teachers to critically investigate digital technologies that blur the distinction between virtuality, material bodies, and realities.

Building on digital rhetoric and technofeminist scholarship, this dissertation …

High Throughput, Solid Sample Analysis With Cone-Based Mass Spectrometric Ionization Sources, Emily J. Wiggins

Theses and Dissertations

The widespread presence of environmental and consumer-product contaminants (e.g. trace metals, opium alkaloids) has underscored the need for rapid, reliable, and high-throughput analytical techniques that are capable of handling complex solid samples. While traditional mass spectrometric (MS) methods tend to have high sensitivity and accuracy, they often require labor-intensive and time-consuming sample preparation steps that limit throughput and field applicability. This thesis investigates the use of 3D-Printed Cone Spray Ionization-Mass Spectrometry (3D-PCSI-MS) as an ambient ionization technique for the direct screening of contaminants from solid matrices, eliminating the need for traditional sample preparation and allowing for real-time analysis.

More Than Players, More Than Coaches: Institutional Agents And Youth Development In Urban And Suburban Minority-Majority Neighborhoods, Rainah N. Folk

Theses and Dissertations

Institutional agents play a crucial role in shaping youth development. While the institutional agent framework is well established in postsecondary research, less is known about its role during mid-adolescence. Using relational ethnography and responsive interviewing, this study compares an urban and a suburban high school in minority-majority neighborhoods in Cook County, Illinois, to explore how development is influenced through relationships between sport coaches and high school athletes. Athletes in both contexts face significant challenges tied to neighborhood conditions and socioeconomic status. In response, coaches form deeply caring and supportive relationships, though their roles diverge in ways shaped by their urban …

The Elemental Analysis Of Groundstone Celts From Noble-Wieting Using The Pxrf: A Provenance Study, Julian A. Marvel

Theses and Dissertations

Groundstone axes, or celts, were prehistoric stone tools used for chopping, cutting, or woodworking. Made from hard stone like basalt or granite, it was shaped by grinding and polishing rather than flaking, giving it a smooth, durable surface. Celts typically have a tapered edge and were often hafted onto wooden handles or used by hand. They were common in Neolithic cultures around the world and served both practical and sometimes ceremonial purposes. In this thesis, I analyze celts from Noble-Wieting (11ML24), a 14th-century Langford tradition village in McLean County, Illinois.

Specifically, my research addresses the following questions about these groundstone …

Rebranding Ink: Language, Identity, And The Rise Of Tatū In Contemporary Japan, Elise M. Ulrich

Theses and Dissertations

In modern Japan, the shift from the traditional term irezumi (入れ墨) to the English loanword tatū (タトゥー) reflects more than just language change—it reveals deeper cultural and social transformations. Loanwords, or borrowed words from other languages, often enter a language through cultural contact, adapting to fit local linguistic and social norms. As the Linguistic Society of America notes, “Most languages have been influenced at one time or another by contact” (Winford, n.d., p. 1). Since World War II, English has become a major source of loanwords in Japanese, shaping everything from everyday conversation to aesthetic trends.

This thesis explores why …

Efforts Towards The Synthesis Of A Potential Protease Inhibitor Against The Main Protease (3clpro) Of Covid-19, Austin J. Carter

Theses and Dissertations

1,2,4-Oxadiazoles are five-membered heterocyclic structures first synthesized by Tiemann and Krüger in 1884. Recent discoveries suggest an array of useful biological properties.In preparation of 1,2,4-oxadiazoles, the most prevalent precursors are amidoximes, which can be created via the reaction of nitriles with hydroxylamine hydrochloride and a base. The amidoximes are reacted with an activated carboxylic acid to yield an acylated intermediate. This intermediate can be exposed to a base to cyclize into the 1,2,4-oxadiazole. This thesis describes the efforts in combining these three steps into a unified one-pot synthesis.

Currently, there are a significant number of commercially available FDA approved and …

The Invisible Tapestry Of Whiteness: A Phenomenological Study Of Campus Artifacts At A Historically White University, Shaun N. Crisler

Theses and Dissertations

BIPOC students at historically white colleges and universities (HwCU) often experience rejection, isolation, and marginalization in campus environments that remain unwelcoming and racially hostile. While research highlights the negative impact of these climates on student success, few studies interrogate whiteness as a structural force, shaping institutional culture and sustaining racial inequities. This study examines how whiteness is embedded in campus artifacts—including history, demography, curriculum, learning environment, climate, symbols, traditions, and spaces—and how it impacts BIPOC students' experiences.

Using a phenomenological approach, this study engaged 15 BIPOC students at Partly Cloudy University through surveys and interviews. Data were analyzed using critical …

A Word Is Worth A Thousand Words: Sustained Alphabetic Narratives And The Academic Success Of English Language Learners At The Secondary Level, Ricardo D. King Jr

Theses and Dissertations

In recent years, English Language Learner (EL) education, more commonly referred to as English as a Second Language (ESL) or Teaching English to Speakers of Other Languages (TESOL), has advocated for a multimodal approach to classroom instruction. At the same time, higher level English Language Arts (ELA) classes continue to use sustained alphabetic narratives without explicit references to multimodal practices (i.g., graphic novels, graphic narratives, comics, picture books, etc.). This disconnect in teacher advocacy and in educational practice has positioned EL students outside of the opportunities offered by higher level ELA coursework and the sustained alphabetic narratives that are taught …

Perceptions And Treatment Decisions For A Drug Offender Based On Social Class, Cocaine Type, Personal Characteristics, And Compassionate Love: A Vignette Study, Yasmin A. Odeh

Theses and Dissertations

Problem: The shift from a focus on rehabilitation to the more punitive, “tough on crime” approach to illegal behavior in the U.S. has been enacted in no small way by policies connected to the use and abuse of drugs. The disparities between crack and powder cocaine—two chemically similar substances—have headlined this shift (Vagins and McCurdy 2006). However, research is scarce on laypeople’s approval of deterrence approaches for drug offenses, including as a function of types (e.g., powder vs. cocaine possession). This study examined people’s perceptions of prosecutorial decisions for drug offenders—whether they are punished, rehabilitated, or both—and whether people perceived …
