Cellulose Membrane Performance And Properties With Focus On Dialysis Application, Juliana Marçal Jul 2026

Cellulose Membrane Performance And Properties With Focus On Dialysis Application, Juliana Marçal

Graduate Theses and Dissertations

Chronic kidney disease affects approximately 35 million individuals in the United States, with nearly 550,000 patients dependent on dialysis for survival. Chronic kidney disease and end stage kidney disease impose substantial burdens on patients and healthcare systems, driving demand for improved dialysis membranes with enhanced flux, selectivity, and biocompatibility. The performance of dialysis membranes plays a critical role in treatment efficiency, governing solute transport, fluid removal, and overall therapeutic outcomes. In hemodialysis, membranes must achieve an optimal balance between high permeability and selective solute rejection while maintaining mechanical stability and long-term biocompatibility. Conventional dialysis membranes are commonly fabricated from polymeric …


A Quantitative Examination Of The Relationship Between College Gpa And Culturally Inclusive Support Services, Sara Jo Barnett Nsakashalo Jul 2026

A Quantitative Examination Of The Relationship Between College Gpa And Culturally Inclusive Support Services, Sara Jo Barnett Nsakashalo

Graduate Theses and Dissertations

The Eurocentric formal education model was first introduced to American Indians as a weapon, a tool by which American Indian culture and lifeways could be dismantled thus forcing the entire population into assimilation. The residual trauma of the Indian Boarding School era and other federal Indian policy continue to impact American Indian students, even at the postsecondary level. For decades, research has focused on exploring the role of Tribal Colleges and Universities (TCU) to explain the increased success American Indian students experience at these institutions when compared to other institutions. Though they have demonstrated an exceptional ability to adequately serve …


Arkansas’ Crippled Children’S Homes & The Politics Of Polio, Rylie Ford Jul 2026

Arkansas’ Crippled Children’S Homes & The Politics Of Polio, Rylie Ford

Graduate Theses and Dissertations

Most of the work in the field of disability history has centered on the Northeastern part of the United States and regions with large urban centers, therefore, excluding Southern and rural perspectives. This omission is particularly problematic when roughly 79% of the Black population in the United States lived in the South in 1940. The aim of this study is to contribute a Southern perspective to disability studies and Black medical history by tracing the development of services and aid for children with physical disabilities in Arkansas. Employing the frameworks from the social model of disability and Black disability politics, …


Religious Higher Education In Prison In The United States: The Importance Of Well-Being, Robin L. Labarbera Jul 2026

Religious Higher Education In Prison In The United States: The Importance Of Well-Being, Robin L. Labarbera

Journal of Global Education and Research

A growing body of scholarship suggests that incarcerated individuals who participate in education programs, particularly those grounded in faith, are better positioned for lasting community reintegration and positive long-term outcomes. Using a mixed-methods evaluation design, the author examines two interrelated questions: whether faith-based higher education is associated with enhanced well-being among current participants and whether program graduates carry those well-being gains into post-release life. Drawing on group interviews with 109 incarcerated men and women across six U.S. facilities and surveys from 157 participants in four states, the study found that participation in a prison-based theological education program was associated with …


Barriers And Enablers Of Integrated E-Learning In Southern Africa: Student Experiences, Vicente A. Halle, Luzaan Schlebusch Jul 2026

Barriers And Enablers Of Integrated E-Learning In Southern Africa: Student Experiences, Vicente A. Halle, Luzaan Schlebusch

Journal of Global Education and Research

Integrated e-learning is increasingly essential for enhancing higher education globally, yet its implementation in resource-constrained regions such as Southern Africa remains uneven. This study explores the technological, organizational, and environmental factors influencing the integration of e-learning in higher education institutions, using the Technological, Organizational, and Environmental framework. A qualitative phenomenological approach was employed, involving semi-structured interviews with 24 students (12 males and 12 females) from universities in South Africa and Mozambique. Thematic analysis revealed key barriers, including poor connectivity, limited digital literacy, inadequate institutional support, and socio-economic constraints such as power cuts and data costs. Despite these challenges, several enablers …

Broadband Diffusion And Digital Preparedness In Tanzania: Harnessing The Role Of Technology In Formal Education, George Matto, John J. Iwata Jul 2026

Broadband Diffusion And Digital Preparedness In Tanzania: Harnessing The Role Of Technology In Formal Education, George Matto, John J. Iwata

Journal of Global Education and Research

Broadband, as a high-speed Internet connectivity, is an essential enabler for digital preparedness. However, little is known, in the case of Tanzania, about the nexus between broadband diffusion and digital preparedness, particularly in the facilitation of the teaching and learning process. This study, therefore, aimed at investigating the nexus between broadband diffusion and digital preparedness in Tanzania by focusing on the country’s readiness to leverage the same for formal education. The study employed a systematic review, guided by the PRISMA framework, to obtain the empirical evidence from existing literature. Thematic analysis was used to identify themes, analyze, and interpret qualitative …


New-Onset Cognitive Impairment After Delirium Among Hospitalised Older Ghanaians: A Pilot Study, John-Paul Omuojine, Richard Dei-Asamoa, Caleb Otu-Ansah, Gertrude Aboah, Belinda Opoku, George Amponsah, Stella Afeti, Leah Ratner, Ruth Owusu-Antwi, Cyprian Mostert Jul 2026

New-Onset Cognitive Impairment After Delirium Among Hospitalised Older Ghanaians: A Pilot Study, John-Paul Omuojine, Richard Dei-Asamoa, Caleb Otu-Ansah, Gertrude Aboah, Belinda Opoku, George Amponsah, Stella Afeti, Leah Ratner, Ruth Owusu-Antwi, Cyprian Mostert

Population Health, East Africa

Background Delirium is a potentially modifiable risk factor for dementia. However, post-delirium cognition has hardly been studied in Africa, where the burden of both disorders is rising disproportionately.

Objective We estimated the incidence of new-onset cognitive impairment (NCI) 6 months after hospitalisation with non-stroke delirium among older Ghanaians.

Methods This was a prospective observational pilot study conducted among 60 previously cognitively unimpaired (retrospective proxy assessment) adults aged ≥60 years, hospitalised with non-stroke prevalent delirium in a Tertiary Hospital. Delirium was confirmed and rated using the Confusion Assessment Method (CAM) and Severity Scale (CAM-S) within 24–72 hours of admission and reassessed …


Undercooked Or Over Easy? Perceptions Of Initial Teacher Educators On The Growth Of Alternative Authority To Teach Contracts, Sharon A. Louth, Linda Mahony Jul 2026

Undercooked Or Over Easy? Perceptions Of Initial Teacher Educators On The Growth Of Alternative Authority To Teach Contracts, Sharon A. Louth, Linda Mahony

Australian Journal of Teacher Education

The practice of employing pre-service teachers (PST) in schools prior to the completion of their teacher training, has grown over the last three years as the teacher shortage across Australia and the world worsens. This study examines the perceived impact of Alternative Authority to Teach (AAT) contracts on the teaching profession through the lens of university lecturers working within the Initial Teacher Education (ITE) space. This phenomenological research sought to gain a wider understanding of the impact of AAT contracts on ITE stakeholders and their PST. Qualitative semi-structured interviews were conducted with eleven university lecturers. A thematic analysis of the …


Pinochet’S Upswing: The Demise Of A Democratic Society In Chile, Jacob Behnk Jul 2026

Pinochet’S Upswing: The Demise Of A Democratic Society In Chile, Jacob Behnk

Honors Program: Senior Projects (Public)

In the United States, we tend to view democracy as an inviolable tenet of political life. Our nation’s founding is even romanticized as a heroic fight for liberty against the wicked tyranny of the British monarchy. It is unthinkable that democracy could ever be destroyed, let alone have the citizens cheer on those who engineer its destruction—yet this is the very situation that Chile found itself regarding Augusto Pinochet, a brutal dictator who ruled the country with an iron fist from 1973 to 1990. Pinochet would be voted out of power in a 1988 plebiscite, but still managed to win …

Addressing Bias Against Sopo Vee Opp Polyamory, Nafees Alam Jul 2026

Addressing Bias Against Sopo Vee Opp Polyamory, Nafees Alam

Social Work Faculty Publications

Polyamory is a consensual relationship style involving multiple romantic and/or sexual partners, with SOPO (solo polyamory), VEE, and OPP (one penis policy) being specific polyamorous dynamics that often face heightened bias. The reality show "Sister Wives" offers a compelling case study of both stigmatization and potential normalization of non-monogamous relationships in mainstream media. This manuscript examines how "Sister Wives" both reinforces and challenges stereotypes about polyamory, its impact on public perception, and how the experiences of the Brown family parallel those of SOPO VEE OPP practitioners. By analyzing media representation alongside lived experiences, we can better understand how to promote …


Animal Assisted Interventions For Older Adults Experiencing Cognitive Impairment, Preeti Bachu Jul 2026

Animal Assisted Interventions For Older Adults Experiencing Cognitive Impairment, Preeti Bachu

Psychology

As individuals age, they often experience gradual declines in cognitive abilities that ultimately affect their quality of life and independence. Severe cognitive decline is not necessarily a natural or universal part of the aging process and tends to be exacerbated by various neurodegenerative diseases, most notably Alzheimer's disease (Colita et al., 2024). There have been promising outcomes of animal assisted interventions in improving the conditions of several populations and spaces, including educational, rehabilitative, and therapeutic settings. Animal assisted therapy specifically is delivered by a qualified or licensed health professional. Previous research has shown a large benefit in long-term memory, verbal …


Examining The Effectiveness Of Nature Metaphor Patterns For Cultivating Intimacy, Acceptance, Relationship Satisfaction, Self-Compassion, And Positive Communication In Couples, Jenna Rice, Sarah Fraher, Elizabeth Engelkamp, Melissa Mcternan, Hannah Grigorian, James Cordova Jul 2026

Examining The Effectiveness Of Nature Metaphor Patterns For Cultivating Intimacy, Acceptance, Relationship Satisfaction, Self-Compassion, And Positive Communication In Couples, Jenna Rice, Sarah Fraher, Elizabeth Engelkamp, Melissa Mcternan, Hannah Grigorian, James Cordova

Psychology

Effective couple interventions, such as Integrative Behavioral Couple Therapy and the Relationship Checkup, include the labeling of common relationship patterns. This study hypothesized that a micro-intervention using nature metaphors, such as “Porcupine–Turtle,” would produce greater improvements in relationship health relative to descriptive labels such as “Approach–Withdraw.” Twenty-five couples were presented with nature metaphor patterns, while 24 couples were presented with descriptive patterns. Several measures of relationship health showed significant improvements across both groups, while other measures showed significant improvements for descriptive patterns only. Generally, nature metaphor patterns were initially rated as more novel and more resonant. Broadly, these results add …


Improving Urban Search And Rescue Team Coordination Through Adaptive Context Awareness, Daniel Reyes Duran Jul 2026

Improving Urban Search And Rescue Team Coordination Through Adaptive Context Awareness, Daniel Reyes Duran

Doctoral Dissertations and Master's Theses

Modern multi-agent Urban Search and Rescue (USAR) operations heavily rely on mobile geospatial Common Operating Pictures (COPs) to maintain team coordination and Situational Awareness (SA). However, the proliferation of high-frequency sensor telemetry at the tactical edge has introduced a data saturation paradox challenge: while information theoretically drives informed decision-making, unmanaged data surges induce increased operator cognitive overload and alert fatigue on mobile End-User Devices (EUDs), while downstream data-broadcasting models inherently strain edge processing and viewport environments.

To resolve these constraints, this dissertation presents a context-aware Value of Information (VoI) data-management framework integrated directly with a custom, event-driven Android Team Awareness …


Polarized Truth Decay & The Role Of Education In A Democracy, Sonja Varbelow, William Yaworsky Jul 2026

Polarized Truth Decay & The Role Of Education In A Democracy, Sonja Varbelow, William Yaworsky

Anthropology Faculty Publications

The purpose of this paper is to delineate the causes and dangers of truth decay for a democracy, the role education has played in the process, and how education can present a resistance to this dangerous trend. Truth decay has been characterized as an increase in quantity of opinion over fact, divergent views on what constitutes a fact, and decreased confidence of traditional sources of information. We agree that truth decay is a serious problem but would characterize it somewhat differently. Opinions, divergent views, and decreased confidence in traditional sources of information are not detrimental by themselves. Instead, we see …


Highly Confident But Slightly Uncertain: A Long Overdue Reinvention Of The School Scientific Method, Uncertainty And Error - Volume 3, Stephen Demeo Jul 2026

Highly Confident But Slightly Uncertain: A Long Overdue Reinvention Of The School Scientific Method, Uncertainty And Error - Volume 3, Stephen Demeo

Publications and Research

Volume 3 explores the essential roles of uncertainty and error in scientific experimentation. It distinguishes between scientific error and scientific uncertainty: Scientific error refers to the difference between an experimental value and an accepted literature value, as well as the difference between data points in an x-y scatter plot and a predicted trendline. Scientific uncertainty, on the other hand, is associated with doubt arising from instrument limitations, variability within a data set, and psychological factors. Human error is set apart as mistakes or blunders, not to be conflated with scientific error.

Of utmost importance to the scientific investigator is the …


Highly Confident But Slightly Uncertain: A Long Overdue Reinvention Of The School Scientific Method, The X - Volume 1, Stephen Demeo Jul 2026

Highly Confident But Slightly Uncertain: A Long Overdue Reinvention Of The School Scientific Method, The X - Volume 1, Stephen Demeo

Publications and Research

In Volume 1, I critique the traditional School Scientific Method—an oversimplified, underdeveloped, and short, stepwise process—and argue for a more authentic, detailed, and rigorous approach to experiment-based scientific inquiry in education. I briefly explain the historical roots of the School Scientific Method, its benefits in increasing the exposure of experimental science to the masses, and its limitations in fostering more authentic scientific thinking and experimental practice.

In place of this traditional and problematic method, I introduce a graphic organizer called sciXpsy to foster both big-picture and detailed scientific thinking. The heuristic combines scientific concepts and methodology with the psychology of …

The Effects Of Abstinence Status And Sleep Quality On Resting State Alpha Power In Cocaine Use Disorder, Heather E Webber, Danielle A Kessler, Joy M Schmitz, Scott D Lane, Robert Suchting

Faculty, Staff and Student Publications

Rationale

Substance use disorders are associated with notable sleep disturbances. Electroencephalogram (EEG) alpha power occurs during wakeful rest, is associated with sleepiness, and indicates neural deactivation.

Objectives

The goal of the current study was to assess the effects of abstinence on the relationship between alpha power and subjective sleep quality in participants with cocaine use disorder (CUD).

Methods

Participants with CUD (n = 32) who were recently or non-abstinent completed a resting-state EEG paradigm (90 s eyes open/closed). Absolute alpha power was calculated using the fast Fourier transform and by averaging within the power spectra of the alpha band (8–13 …

Introduction: Cerebral amyloid angiopathy (CAA) is associated with cognitive impairment, but its longitudinal course of cognitive decline remains unclear. We investigated domain-specific cognitive trajectories in Dutch-type hereditary (D-CAA) and sporadic CAA (sCAA) to compare patterns and rates of decline. Methods: We included 181 participants – 93 D-CAA mutation carriers (59 without, 34 with prior intracerebral hemorrhage [ICH]) and 88 with sCAA (57 without, 31 with ICH) – who underwent annual neuropsychological assessment. Longitudinal change in global cognition, memory, processing speed, and executive function was analyzed using linear mixed models. Results: Over 5 years, cognitive decline was subtle but measurable. Memory …

Why Are Western Australian Girls Less Motivated Than Boys To Study Senior Secondary Higher-Level Mathematics Courses? Relationships Between Gender, Prior Achievement, And Mathematics Course Aspirations, Jane Kirkham, Elaine Chapman

Research outputs 2022 to 2026

Secondary school students, and particularly girls, may avoid enrolling in higher-level mathematics courses despite having the competence to succeed in these courses. Understanding the reasons behind these choices is essential to addressing this concern. In this study, the teachers of Western Australian Year 10 students (n=886) nominated the mathematics course in which they believed each participating student could succeed in Year 11 with participants grouped into four achievement cohorts on this basis. Then each teacher course nomination was compared to participants’ own course selection with participants classified as either aspiring below or at/above their judged potential achievement level. We then …

Moderation and simple slope analyses were employed in the cohort as a whole and following stratification by sex.

Results: Fiber intake moderated the relationship between change in depressive …


Physical Inactivity In Preclinical Alzheimer's Disease: Risk Factor, Early Symptom, Or Both, Jiawei Zhao, Xin Li, Mengxuan Wu, Zhanjun Zhang Jul 2026

Physical Inactivity In Preclinical Alzheimer's Disease: Risk Factor, Early Symptom, Or Both, Jiawei Zhao, Xin Li, Mengxuan Wu, Zhanjun Zhang

Communication Sciences & Disorders Faculty Publications

Physical inactivity is a key modifiable risk factor for Alzheimer's disease (AD). However, emerging evidence suggests a bidirectional relationship where inactivity also serves as an early manifestation of AD pathology. This perspective synthesizes recent findings from long-term epidemiological cohorts, brainstem neuropathology, and digital phenotyping to reconceptualize the role of inactivity in preclinical AD. Early tau accumulation in catecholaminergic nuclei (locus coeruleus and ventral tegmental area) disrupts circuits essential for reward valuation and effort calculation. We hypothesize that this neurobiological failure may manifest as prodromal apathy and declining physical activity years before cognitive impairment. Standard metrics like step counts fail to …


Operational Agency: A Permeable Legal Fiction For Tracing Culpability In Ai Systems, Anirban Mukherjee, Hannah H. Chang Jul 2026

Operational Agency: A Permeable Legal Fiction For Tracing Culpability In Ai Systems, Anirban Mukherjee, Hannah H. Chang

Research Collection Lee Kong Chian School Of Business

Modern artificial intelligence (AI) systems act with a high degree of independence yet lack legal personhood—a paradox that fractures doctrines grounded in human-centric notions of mens rea and actus reus. This Article introduces Operational Agency (OA)—a permeable legal fiction structured as an ex post evidentiary framework—and Operational Agency Graph (OAG)—a tool for mapping causal interactions among human actors, organizations, and AI systems. OA evaluates an AI’s observable operational characteristics: its goal-directedness (as a proxy for intent), predictive processing (as a proxy for foresight), and safety architecture (as a proxy for standard of care). OAG operationalizes that analysis by embedding these …
