Theses and Dissertations

The purpose of this study was to explore the perceptions of mental health school-based team members regarding the effectiveness of current prevention and intervention practices for addressing suicidal and non-suicidal self-harming behaviors among school-age children in a large suburban school district in the southern United States. Despite the alarming increase in self-injurious behaviors, with crisis calls rising from 144 incidents in the 2022 school year to 736 incidents in the 2025 school year, the district lacked comprehensive prevention and intervention strategies to effectively address this critical issue.

The researcher used a qualitative phenomenological approach to capture the lived experiences and …


Perceptions Of Victims On The Influence Of Domestic Violence Programs On The Decision To Leave, Tiffany Kleiman-Bourdeau Jan 2025

Perceptions Of Victims On The Influence Of Domestic Violence Programs On The Decision To Leave, Tiffany Kleiman-Bourdeau

Theses and Dissertations

Dating back to earlier times, domestic violence was referred to as marital disputes and was not even considered a crime by law enforcement. However, that has since changed and now individuals are convicted for such crimes against another person. There are several treatment plans and options for these abusive individuals to take to receive the help they need to refrain from being abusive towards others, but what of the victims? What programs and/or services are available to them? Do these services even help the victims? This Idea Paper will examine the effectiveness of the programs and services available to domestic …

Video game user experience is influenced by many factors such as graphics and audio, gameplay mechanics, user interface design, etc. The present study aims to explore whether spatial abilities influence and are significantly correlated with user experience for games using heads-up displays …


The Effect Of Need For Cognition & Need For Affect On Human Reliance And Artificial Intelligence Interactions, Aliyah Mcgowan Jan 2025

The Effect Of Need For Cognition & Need For Affect On Human Reliance And Artificial Intelligence Interactions, Aliyah Mcgowan

Doctoral Dissertations and Master's Theses

Abstract

With the increased use of Artificial Intelligence (AI) automations in fields like medical diagnoses and mental health queries, there are concerns regarding an individual’s trust and reliance on the technology. Reliance on AI output may lead an individual to accept inaccurate or incorrect information without further analysis. Trust may influence reliance and trust formation may be a product of affective processing. This study investigated the relationship between Need for Affect (NFA), Need for Cognition (NFC), and trust and reliance on AI interactions. Participants were assessed on the NFA scale for willingness to approach or avoid emotional stimuli, the NFC …

After median imputation and data cleaning, continuous features were normalized and the cohort was divided into 70 % training and 30 % test sets. RF scored 97 % with an AUC of 1.00 on its own, and SVM …


Enhancing Throughput In A Network Function Virtualization Environment Via The Manta Ray Foraging Optimization Algorithm, Sanaa S. Alwan, Asia Ali Salman Jan 2025

Enhancing Throughput In A Network Function Virtualization Environment Via The Manta Ray Foraging Optimization Algorithm, Sanaa S. Alwan, Asia Ali Salman

Mesopotamian Journal of Big Data

Network function virtualization (NFV) has emerged as a transformative paradigm in which traditional hardware appliances are replaced with virtual network functions (VNFs) running on commodity hardware. While NFV offers scalability and flexibility, it faces major challenges in sustaining high throughput and minimizing resource overhead under dynamic traffic conditions. In particular, flooding algorithm-based request propagation often leads to excessive redundancy, congestion, and resource waste. To address this limitation, this study applies Manta ray foraging optimization (MRFO), a swarm intelligence algorithm inspired by natural foraging behaviors, to optimize packet routing and resource allocation in NFV environments. The research employs a Barabási–Albert (BA) …


Becoming The Donkey Derby’S ‘Karen’: A Humane Educator’S Autoethnographic Journey Toward Anti-Speciesist Communication, Jesika Keener Jan 2025

Becoming The Donkey Derby’S ‘Karen’: A Humane Educator’S Autoethnographic Journey Toward Anti-Speciesist Communication, Jesika Keener

Antioch University Dissertations & Theses

Language not only carries oppression as an educative force, but research indicates that language is inherently speciesist and highly pervasive (Ethical Globe, 2021; Guevara Labaca, 2017; Hamlett, 2024; Leach et al., 2023). However, the ontological commitment to speciesism is historically foundational, which makes the total eradication of speciesist communication only viable through an unemerged hypothetical future society (Kahn, 2011). For the possibilities of such a world to come into being, pivotal steps must first be taken to critically engage with the communicated forms of speciesism in order to better understand it and actively resist its reproduction—with the aspiration for this …


Proposed Principles Beyond Human And Non-Human Binaries: Engaging A Kincentric View In Environmental Education, Christine Marie Widrig Jan 2025

Proposed Principles Beyond Human And Non-Human Binaries: Engaging A Kincentric View In Environmental Education, Christine Marie Widrig

Antioch University Dissertations & Theses

This is a crucial time for a call to an awakened consciousness toward respectable, equitable, and expansive relationships and agency with the natural world. Indigenous philosophy and practices offer alternative visions for cultivating representations of language, narrative, and tradition that expand boundaries of modern Western thought and discourse. Key to many Indigenous traditions is fostering relationships of kin(ki), meaning kinship, within diverse ecological landscapes and place, while engaging respectfully with the non-human world. These alternative ways of consciousness and agency can be vital means of supporting healthy biodiversity and conservation, amid spiritual practices. In this dissertation, I propose and outline …


An Examination Of Harm During The Real-Life Experience, Michelle E. Balch Jan 2025

An Examination Of Harm During The Real-Life Experience, Michelle E. Balch

Antioch University Dissertations & Theses

The Real-Life Experience (RLE) has been described as a coercive and arbitrary requirement without evidence of validity or reliability. This can cause more harm than it prevents for a significant subset of transition-seeking transgender clients. For these reasons the RLE was dropped from the WPATH Standards of Care after version six. However, the RLE has been adopted by a number of health insurance companies as a measure of readiness to receive transition services. An Interpretative Phenomenological Analysis (IPA) and semi-structured interviews of five individuals were conducted to evaluate their perceptions of RLE and the meaning they attach to their broader …


The Experience Of Psychologists In Providing Unexpected Feedback During Neurodevelopmental Evaluations, Alyssa J. Mayer Jan 2025

The Experience Of Psychologists In Providing Unexpected Feedback During Neurodevelopmental Evaluations, Alyssa J. Mayer

Antioch University Dissertations & Theses

The purpose of this study was to describe the experience of licensed psychologists who provided unexpected feedback to assessment clients about not meeting the criteria for neurodevelopmental disorders. Individuals are increasingly seeking formal evaluation for neurodevelopmental disorders based on anecdotal information they come across on the internet. Many people develop strong identity attachments to these diagnostic labels, and it can be incredibly dysregulating to learn that they do not meet the criteria for a diagnosis. Six psychologists participated in semi-structured virtual interviews to share their experiences providing clients with this type of unexpected feedback. Through an interpretive phenomenological analysis framework, …

Intraspecific Variation In Plant–Fungal Interactions Across Tidal Elevation In A Salt Marsh, Torrie Hanley, Catherine Gehring, Ron Deckert, Behzad Mortazavi, Christina Richards, A. Randall Hughes Jan 2025

Intraspecific Variation In Plant–Fungal Interactions Across Tidal Elevation In A Salt Marsh, Torrie Hanley, Catherine Gehring, Ron Deckert, Behzad Mortazavi, Christina Richards, A. Randall Hughes

Biology Faculty Publications

Interspecific interactions vary depending on environmental and genetic factors, with intraspecific variation potentially altering these relationships. Specifically, intraspecific variation within host plants and their endosymbionts may affect above- and belowground interactions depending on environmental conditions. We examined how intraspecific variation within the salt marsh foundation species Spartina alterniflora and a common fungal root endosymbiont (Lulworthia sp.) affected their interactions. We conducted a glasshouse experiment comparing interactions between Spartina growth forms (tall-form from low marsh and short-form from high marsh) and Lulworthia isolates from different marsh locations, and a laboratory experiment exposing Lulworthia isolates from both endpoints of a tidal elevation …


Comparing The Development And Viability Of Horseshoe Crab Eggs Laid In Beach And Salt Marsh Habitats, Daniel A. Sasson, Christopher C. Chabot, Jo-Marie Kasinak, Jennifer Mattei Ph.D., Elizabeth U. Scott, Fletcher K. Hall, Michael R. Kendrick Jan 2025

Comparing The Development And Viability Of Horseshoe Crab Eggs Laid In Beach And Salt Marsh Habitats, Daniel A. Sasson, Christopher C. Chabot, Jo-Marie Kasinak, Jennifer Mattei Ph.D., Elizabeth U. Scott, Fletcher K. Hall, Michael R. Kendrick

Biology Faculty Publications

The horseshoe crab, Limulus polyphemus, has recently been found to spawn regularly in salt marshes, despite the long-held assumption that salt marsh sediments are not conducive for embryonic development. Here, we tested the prediction that eggs laid in the salt marsh would develop more slowly and be less viable than eggs laid on beaches. We flagged the nests of spawning horseshoe crabs in the marshes and beaches of three states—South Carolina, Connecticut, and New Hampshire—and then excavated those nests one or three weeks later. We staged the excavated embryos to compare developmental progress between marshes and beaches. We found …

The goal of the Task Force is to create a nursing resource list that represents current materials and formats, uses a selection process that is transparent and reproducible, and will be available to a broad …


Attention's Loop: A Sculptor's Reverie On The Coexistence Of Substance And Spirit, Elizabeth King, Katherine Wetzel Jan 2025

Attention's Loop: A Sculptor's Reverie On The Coexistence Of Substance And Spirit, Elizabeth King, Katherine Wetzel

Attention's Loop

This is a book about attention and memory. I am a sculptor, so it is also a book about size, dirt, artifice, work, and eye. The text is a set of stories and interruptions that pile up to make a play of overlapping loops. My organizing principle is the image of the round-trip, so one may open the book and step into it at any point. Most of Katherine Wetzel’s photographs are of a single sculpture. It is a self-portrait, a particular kind of round-trip, and it is small: one-half life-size. Called Pupil, it is jointed and movable, and …

Repositioning Antimalarial Drugs As Anticancer Agents: Focus On Tafenoquine, Chris Barton Jan 2025

Repositioning Antimalarial Drugs As Anticancer Agents: Focus On Tafenoquine, Chris Barton

Funded Scholarship

Due to the expensive and lengthy process of drug design and approval, drug repurposing (or repositioning) has become another option for identifying preexisting molecules that may be used for alternative purposes. Recently, some antimalarial compounds have been shown to display efficacy against cancer cell proliferation. In this study, we provide evidence to suggest that multiple preexisting antimalarial drugs can reduce the viability of human cancer cells in culture. Furthermore, we provide the first evidence that one antimalarial, Tafenoquine (LD50 = 9.6 μM in HCT116 cells), is capable of decreasing viability with an efficacy comparable to Etoposide (LD50 = 15.2 μM …


A Multidisciplinary Approach To The Thermal And Non-Thermal Mechanisms In Galaxy Clusters, Sheng-Chieh Lin Jan 2025

A Multidisciplinary Approach To The Thermal And Non-Thermal Mechanisms In Galaxy Clusters, Sheng-Chieh Lin

Theses and Dissertations--Physics and Astronomy

Galaxy clusters form at the intersections of the cosmic web and carry imprints of the structure formation history of the universe. As massive, multi-component systems, they offer unique insights into the astrophysical processes that govern both structure formation and galaxy evolution. Observable across the full electromagnetic spectrum, clusters emit photons through a variety of mechanisms, each tracing different physical processes. This dissertation investigates both the thermodynamic and non-thermal properties of the intracluster medium (ICM) to better understand the physical processes shaping observed phenomena. It comprises three main studies, each targeting a different aspect of galaxy cluster physics. In the second …


From Affirmation To Equity: The Spiral Of Congregational Empowerment For Women In Baptist Congregations, Heather E. Deal, Will Ward, Gaynor I. Yancey Jan 2025

From Affirmation To Equity: The Spiral Of Congregational Empowerment For Women In Baptist Congregations, Heather E. Deal, Will Ward, Gaynor I. Yancey

Funded Scholarship

Patriarchy has long structured Christian life and practice. In many Baptist settings, even formal affirmations of women in leadership leave a gap between stated commitments and women’s lived experience. This study investigates how Baptist congregations cultivate empowering environments for women by tracing the interplay of beliefs, practices, and processes through which theology is enacted in congregational life. Drawing on feminist theology and lived-religion perspectives, and using constructivist grounded theory, we conducted nine semi-structured interviews with 15 women clergy across seven U.S. Baptist congregations. Analysis proceeded through iterative initial, focused, and theoretical coding with attention to reflexivity and trustworthiness. Findings highlight …


Spectral Divergence Prioritizes Key Classes, Genes, And Pathways Shared Between Substance Use Disorders And Cardiovascular Disease, Everest Castaneda, Elissa Chesler, Erich J. Baker Jan 2025

Spectral Divergence Prioritizes Key Classes, Genes, And Pathways Shared Between Substance Use Disorders And Cardiovascular Disease, Everest Castaneda, Elissa Chesler, Erich J. Baker

Funded Scholarship

Substance use disorders (SUDs) are heterogeneous diseases with 

overlapping biological mechanisms and often present with co-occurring disease, 

such as cardiovascular disease (CVD). Gene networks associated with SUDs 

also implicate additional biological pathways and may be used to stratify 

disease subtypes. Node and edge arrangements within gene networks impact 

comparisons between classes of disease, and connectivity metrics, such as 

those focused on degrees, betweenness, and centrality, do not yield sufficient 

discernment of disease network classification. Comparatively, the graph 

spectrum’s use of comprehensive information facilitates hypothesis testing 

and inter-disease clustering by using a larger range of graph characteristics. 

By adding a connectivity-based …

Wondrous Uncertainty: Transforming Student Educational Experiences Using Restorative Practices, Zachary C. Schafer Jan 2025

Wondrous Uncertainty: Transforming Student Educational Experiences Using Restorative Practices, Zachary C. Schafer

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

One of the primary purposes of education is to help students make sense of their lived experiences. In the process of becoming, students navigate multiple relationships (school, peers, adults, and with self). These relationships often cause conditions of uncertainty which can be managed and transformed using restorative practices in tandem with the academic disciplines taught in school. Over the last decade this has been my inquiry puzzle, “As educators, how can we embrace uncertainty with students as a way of helping to empower them through their dignity, with the academic disciplines as a lens through which relational learning occurs in …


Group And State-Specific Estimation In Animal Movement Models Using A Bayesian Approach, Anita Bhandari Sharma Jan 2025

Group And State-Specific Estimation In Animal Movement Models Using A Bayesian Approach, Anita Bhandari Sharma

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This research study investigates statistical approaches for modeling the movement patterns of white-tailed deer in Louisiana using GPS tracking data. We start by classifying the latent behavioral states using a hidden Markov model (HMM) and then integrate those inferred states into a state-dependent step selection framework to evaluate the land cover preferences. Standard HMMs, however, assume the same movement patterns for all animals, overlooking the differences due to characteristics such as sex, age, breeding season, etc.

To address this limitation, we extend the modeling framework to incorporate the group-level structure defined by similar characteristics or conditions to assess whether such …
