Integrating Perspectives Of People With Aphasia: A Holistic Approach To Community Aphasia Groups Within An Intensive Comprehensive Aphasia Program, Mckinlee A. Mihelish

Graduate Student Theses, Dissertations, & Professional Papers

Introduction: People with aphasia (PWA) experience chronic communication deficits that impact daily life. Community Aphasia Groups (CAGs) are commonly used to address these challenges and have demonstrated psychosocial and communicative benefits; however, they lack standardized structure and are implemented with variability across settings. Additionally, much of the existing research focuses on group-level outcomes rather than participant-driven priorities, limiting clinicians’ ability to tailor interventions. This study examined what PWA want from CAG participation and how these priorities may change over time.

Methods: This quantitative study investigated priority changes among PWA participating in a CAG within a summer 2025 Intensive Comprehensive Aphasia …

What Really Matters In Behavioral Cough Suppression Therapy? A Retrospective Look At Targeted Treatment Components, Mary B. Walsh, Laurie Slovarp, Kassidi Heinle, John Quindry, Jane Salois

Graduate Student Theses, Dissertations, & Professional Papers

Background: 
Refractory chronic cough (RCC) is a prevalent condition that substantially impairs quality of life and is associated with significant physical, psychological, and social burden. Behavioral cough suppression therapy (BCST), delivered by speech-language pathologists, is an evidence-based nonpharmacologic intervention shown to improve cough-related quality of life. However, variability exists in how BCST is implemented, and the relative contribution of specific treatment components remains unclear.

Objective: 
To evaluate the effectiveness of a BCST program implemented in a community otolaryngology clinic that emphasizes consistent suppression at the urge-to-cough and neuroplasticity-informed behavioral principles.

Methods: 
This observational retrospective case series examined clinical records of …

Tourism And Local Access On The Public Beaches Of Paros, Greece, Maria Kouidi

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines how tourism development affects public beach access on the island of Paros, Greece. In recent years, Paros has experienced significant tourism growth, which has contributed to economic development while also placing pressure on natural resources, infrastructure, and coastal spaces. Beaches are protected as public goods under the Greek constitution; however, there are concerns regarding commercialization, overcrowding, and the illegal privatization of these public spaces. This thesis uses a qualitative research approach to explore how these changes are experienced and understood by different stakeholder groups. Data were collected through semi-structured interviews conducted in Paros in July 2025. Participants …

An Exploratory Analysis Of The Role Of Sex In Load Carriage, Rachel E. Perez, Dustin R. Slivka, Brent C. Ruby

Graduate Student Theses, Dissertations, & Professional Papers

Axially loaded weight may impose a metabolic demand equivalent to that of fat mass (FM) during load carriage. Males (M) typically have a lower body fat percentage than females (F), resulting in metabolic demand differences during load carriage that may be mitigated by accounting for FM in pack loads. PURPOSE: To determine whether normalizing pack load to FM equalizes metabolic cost across sexes during load carriage. METHODS: Twenty-eight participants (14M, 23 ± 5 y, 1.81 ± 0.07 m, 78.7 ± 10.0 kg, 12.7 ± 5.4% body fat, VO₂peak 4.18 ± 0.54 L·min^-1; 14F, 22 ± 4 …

The Laymen's Conceptualization Of The “Safe Space”, Tiffany A. Nord

Graduate Student Theses, Dissertations, & Professional Papers

The term "safe space" appears frequently across academic, organizational, therapeutic, and social contexts, yet lacks conceptual clarity. While originating from LGBTQ+ and women's activist movements, contemporary usage has expanded without theoretical development, making it confusing and challenging to effectively implement for researchers and practitioners alike. This two-phase qualitative study examined how individuals define safe spaces. Phase 1 employed an open-ended questionnaire with 62 general population participants. Phase 2 involved semi-structured interviews with 22 self-identified LGBTQ+ individuals. Data were analyzed using a constructivist grounded theory methodology. Findings revealed five core elements: specified setting, enacting responsiveness, allowing candor, perceiving security, and sensing …

Velocity Based Training In Athletic Development, Ross Martin Sangalang

Graduate Student Theses, Dissertations, & Professional Papers

The foundation of high-level sport performance is the ability to produce and express force rapidly across the task-specific temporal demands of sport. Traditional percentage-based prescription methods have long been used to develop hypertrophy, maximal strength, and power; however, fixed %1RM prescriptions fail to account for daily undulations in athlete readiness, accumulated fatigue, and changes in neuromuscular capacity. Velocity based training (VBT) offers a practical framework to regulate training through measurement of concentric velocity, allowing coaches to more accurately prescribe loads, stringently monitor repetition quality, and precisely regulate fatigue. This review discusses the neuromuscular qualities underpinning success in athletic endeavors, limitations …

Heart Of Stone: Geomorphization Through Stone-Oriented Affects, Grace F. Foster

Graduate Student Theses, Dissertations, & Professional Papers

This thesis draws from the work of geologist Marcia Bjornerud to bring a scientific (specifically geologic) understanding of humanity’s relationship to our home planet to bear in a literary context. I employ Bjornerud’s term “geomorphization” to expand from inter-species kinship to inter-substance kinship and to establish stone as an active, lively subject without relying on anthropomorphization. Geomorphization as I define it refers to recognizing similarity between ourselves and stone/Earth on the basis of our stoniness rather than stone’s human-ness. Geomorphizing ourselves entails what Bjornerud calls “timefulness,” a geologic perspective on temporality that sees the past as continually acting in the …

Cormac’S Court: Knights Without God In A Savage Land; Or, Chivalry And Existentialism In Cormac Mccarthy’S The Road, Zoë Margaret Metelerkamp

Graduate Student Theses, Dissertations, & Professional Papers

Cormac McCarthy scholars have examined the influence of romantic grail quest literature and existential philosophy on McCarthy’s oeuvre, but they have treated these subjects independently of each other. This thesis offers a novel exploration of McCarthy’s use of these specific philosophical and literary precedents by focusing on the ways The Road unifies medieval literary principles in Chretien’s Perceval with the existential chivalry Søren Kierkegaard extrapolates in Fear and Trembling.

Hope For The Drowned: Baptism, Faith, And The Open Community Of Grace In Marilynne Robinson’S Housekeeping And Lila, Mackenzie M. Miller

Graduate Student Theses, Dissertations, & Professional Papers

This thesis explores the baptismal imagery across two of Marilynne Robinson’s novels, Housekeeping and Lila. The hermeneutic used to understand baptism is based on some of the works of Rowan Williams, Mircea Eliade, and Northrop Frye. In its death and rebirth function, baptism is understood for its connection to the formation of self and identity. Baptism is also explored as a means of community initiation. Further, connecting these two baptismal functions, this thesis also looks at the role community plays in the formation of that identity. In this process, I compare Housekeeping’s Ruth and Lila’s titular character; …

Bridging The Gap: Evaluating Gnss-Derived Total Water Storage As A Groundwater Monitoring Tool In The Colorado River Basin, Michelle Lee Barton

Graduate Student Theses, Dissertations, & Professional Papers

Groundwater resources in the Colorado River Basin are critically stressed yet remain under-monitored and under-regulated, creating urgent need for reliable, continuous observations at multiple spatial scales. This study evaluates the performance of the University of Montana Global Navigation Satellite Systems (GNSS) terrestrial water storage dataset as a tool for bridging groundwater monitoring gaps across the Upper and Lower Colorado River Basins between 2006 and 2024. We compare GNSS-derived total water storage and groundwater storage estimates against NASA’s Gravity Recovery and Climate Experiment (GRACE) satellite observations and in-situ groundwater well measurements at regional and sub-regional scales. We employ a Bayesian autoregressive …

An Evaluation Of Aquatic Interventions To Support Increased Physical Fitness Levels For Children With Cerebral Palsy, Grace Kasberger

Cal Poly Humboldt theses and projects

This study was designed to determine the most appropriate aquatic interventions to best improve physical fitness levels in children with cerebral palsy (CP). Children with CP often experience reduced aerobic capacity, muscular strength, and functional mobility, which can limit participation in traditional land-based physical activities such as walking and playing. Aquatic environments provide safe and resistance-based environments that can reduce joint loading, spasticity, and provide training. This systematic review examined a variety of different aquatic interventions (e.g. HIIT, aerobic based, strength training, flexibility, and the Halliwick Method) to improve physical fitness in children with CP. Data collection focused on outcomes …

The garden was planned in September, built in October, and had plants in the ground by November. Over the course of the project, I facilitated four workshops, one Earth Day community event, and weekly garden classes. Approximately 350 students participated in the garden in some capacity, reflecting broad, school-wide engagement.

Methods included participant observation, documentation of student engagement, and …

The Effects Of Expectancies And Attention To Placebo Relevant Sensations On The Open-Label Placebo Response, Miranda Connelly

Cal Poly Humboldt theses and projects

Placebo analgesia has shown promise in treating pain, but practitioners are reluctant to prescribe deceptive placebos. Open-label, or honestly prescribed placebos, offer an ethical alternative. Open-label placebos seem to work largely through experimenter-manipulated expectancy, as well as social/environmental factors. Additionally, verbally guided attention to relevant placebo sensations might bolster pain relief. In the present study, expectancy and attention were experimentally manipulated within a 2 (expectancy: high/low) x 2 (attention: high/low) between-subjects design with a no-treatment comparison group. Pain was experimentally induced in all five experimental groups using the well-established cold pressor task. The primary dependent variables were pain tolerance and …

Rethinking Belonging In First-Year Student Support: A Mixed-Methods Evaluation Of Eop/Sss Programing At Cal Poly Humboldt, Elizabeth Rose Silver

Cal Poly Humboldt theses and projects

This mixed-methods project examines the role of the Educational Opportunity Program and Student Support Services (EOP/SSS) first-year orientation programs, particularly STEM Summer Bridge, in supporting feelings of belonging and persistence. While institutional efforts often frame student success through metrics such as retention and concepts like sense of belonging, this project interrogates how these are experienced and understood by students themselves. Quantitative analyses compared one-year persistence rates between STEM Summer Bridge participants and multiple comparison groups across three cohorts (2022–2024). Results showed no statistically significant differences in persistence; however, STEM Summer Bridge participants demonstrated persistence rates comparable to or slightly higher …

Taking A Seat In The Circle: Decolonizing Gender Roles That Argue Against The Participation Of Feminine Bodies At The Big Drum, Juli Suzukawa

Cal Poly Humboldt theses and projects

The origins of the Big Drum can be traced back to the 1860s when Tail Feather Woman, a Dakota woman, had a vision of its creation as a tool of resistance. The Big Drum has since expanded and can now be seen at various Indigenous ceremonies and social events. However, there has been controversy regarding the participation of feminine and queer bodies. While reasons for this vary, it has also contributed to harm amongst Indigenous youths that have a more fluid stand on gender identity and may not conform to colonial “gender norms”. In this paper, I will explore how …

Depth And Soil Physical Context Govern Soil Organic Carbon, While Woody Cover Moderates Native Vegetation Relationships In California Rangelands, Dabid Zuniga Garcia

Cal Poly Humboldt theses and projects

Soil organic carbon (SOC) is central to soil function and an important component of climate mitigation in rangeland ecosystems, but the controls on SOC across California’s working rangelands remain understudied. Using data from Point Blue Conservation Science’s Rangeland Monitoring Network, this study evaluated how soil properties, vegetation structure, and recent climate relate to SOC concentration at depths of 0–10 cm and 10–40 cm across 145 ranches spanning four California regions. Linear mixed-effects models showed that SOC was consistently higher in topsoil than subsoil and highest in coastal sites relative to interior valleys. Bulk density was the strongest negative predictor of …

"What Power Do We Have?" Community Capacity And Justice In Samoa, California’S Floating Offshore Wind Terminal Development, Lauren Mccall Hart

Cal Poly Humboldt theses and projects

Floating offshore wind (OSW) is a relatively novel technology in the United States, which is positioned to play an integral role in California’s decarbonization strategy. Two federal OSW lease areas have been established off the coast of Northern California, and plans are underway to develop supporting port infrastructure, including the Humboldt Bay Offshore Wind Heavy Lift Marine Terminal (HLMT). The proposed HLMT site is adjacent to communities on the Samoa Peninsula of Humboldt Bay, which currently face socio-environmental vulnerabilities and critical infrastructure gaps. The social implications of OSW port development remain poorly understood, particularly in rural and underserved communities. This …

Beyond The Meter: Frameworks For Evaluating The Broad Spectrum Of Microgrid Benefits, Elias Henderson

Cal Poly Humboldt theses and projects

Community-scale microgrids can create a range of social benefits. These include resilient electricity, cleaner air, decarbonization, and economic development, alongside more qualitative values like energy sovereignty and community self-determination. Many such benefits, however, are illegible to California’s market and regulatory frameworks. This thesis traces this disconnect, with particular attention to grid-edge communities in Northern California.

Microgrid benefits are classified as monetized, modeled, or incommensurable according to their inclusion/exclusion in existing regulatory and revenue mechanisms. To explore each category, a mixed-methods analytic approach is employed, pairing Tribal and stakeholder interviews with the development of a microgrid valuation calculator. This tool is …

Symmetry In Affiliative Interactions Of North American River Otters (Lontra Canadensis) In A Northern California Estuary, Charlotte E. Norman

Cal Poly Humboldt theses and projects

Patterns of participation in affiliative behaviors may reflect underlying social dynamics. Two affiliative behaviors, allogrooming and social play, were assessed for their symmetry, or relative participation of participants, in a wild group of North American river otters. Behavioral observations were conducted over five months at the Little River estuary in northern California using video recordings and all-occurrence sampling. Observations included all-adult groups, a family group consisting of a breeding female and two pups, and an extended family group with one or two helpers, indicative of cooperative breeding. Individuals engaged in allogrooming and social play were classified by their group membership, …

A Narrative Analysis Of Equity-Focused Cs Educators: A Multiple Case Illustration, Aleata Hubbard, Jen Tsan

Journal of Computer Science Integration

Background and Context. Equity-focused CS teaching is often prescribed as a solution for addressing disparities in K–12 CS participation and disengaging student experiences. However, adopting such an orientation can be challenging as it pushes educators to shift their teaching beliefs, identity, and practices. Objective. This study examines how the personal and professional experiences of four high school CS teachers influenced their paths to becoming equity-oriented practitioners. We illustrate variation in these developmental trajectories and advance theory building around equity-focused CS teacher identity development. Method. We utilized a multiple-case narrative inquiry approach, collecting data through in-depth, semi-structured interviews that included a …

Does Volunteering Give An Extra Health Boost? Volunteering And Hypertension Risk Among Insured And Uninsured U.S. Adults In Late Midlife, Byeongju Ryu, Seoyoun Kim, Koichiro Shiba, Cal J. Halvorsen

Brown School Faculty Publications

Introduction: Hypertension is a major predictor of cardiovascular disease, a leading cause of death in the U.S. Growing evidence suggests that formal volunteering in later life may reduce hypertension risk; however, it remains unclear whether these benefits extend to adults in late midlife and whether they differ by health insurance status.

Methods: This prospective cohort study analyzed data from the 2012–2018 Health and Retirement Study. The analytic sample included 4,169 respondents between the ages of 50 and 64. Because blood pressure was measured in half the sample in alternating waves, data were pooled across waves. To address selection into volunteering, …

Humanizing The Base Of The Pyramid: Exploring The Influence Of Resource (Dis)Advantages On Value Creation, Ted London, Lisa Jones Christensen, Tyson Mackey, Alison Mackey, Heather Esper, Andrew Grogan-Kaylor

Faculty Publications

Base of the pyramid (BoP) scholarship emphasizes the potential for enterprises to generate profits by enhancing the wellbeing of the impoverished, often by selling socially-beneficial products (SBPs). Yet, many such BoP enterprises have experienced mixed results. We argue that this may stem from insufficient attention to how BoP consumers value SBPs and other products. We frame SBPs as a type of human capital investment and thus use human capital theory to study how the consumption of SBPs does or does not create value for consumers. Specifically, we use a novel data set from rural India to measure value creation in …

Contingent Value Of Coopetition In Business Clusters From A Resource-Based View: A Moderated-Mediation Model, George Vandyck, Christopher Agyapong Siaw, Jonas Aryee, Shikhar Bhaskar, Chiwuokem Nwoko, Rahul Govind

Plymouth Business School

This study examines how perceived cluster resource attractiveness (PCRA) shapes coopetition among co-located firms and how coopetition translates those resource perceptions into knowledge sharing and innovation. Building on the resource-based view, we model coopetition as the mechanism through which managers leverage valuable, unique, and complementary cluster resources into firm outcomes, and we theorize that engagement mode in cluster activities conditions this translation. Using survey data from 221 firms in a business cluster, we estimate a moderated-mediation model with regression and corroborate the results with a latent-variable SEM robustness check. Findings show that PCRA increases coopetition, and coopetition in turn enhances …

"Junk Science" Or Admissible? The Role Of Psychological Profiling In Serial Homicide Trials, Alice Gnesin

Florida Atlantic University Undergraduate Law Journal

In many homicide trials, juries have to consider more than just forensic and testimonial evidence. Sometimes, a perpetrator’s actions can appear illogical or unexplainable, and in this case, juries have to examine and consider the mental state, possible motivations, and behavioral patterns of the perpetrator. Psychological profiling, also known as behavioral analysis, has been used in criminal investigations for years. But even after all these years, many still question its legitimacy. This article examines the effectiveness of behavioral analysis when used as expert testimony in serial homicide cases through the evidentiary standards under Frye v. United States, Daubert v. Merrell …

When Parenting Becomes Production: Family Vlogging, Child Labor, And The Law's Silence, Morgan Robinson

Florida Atlantic University Undergraduate Law Journal

The rise of family vlogging and the ability to earn revenue from the internet through monetization programs have ushered in a new era of child stars. So-called “kidfluencers” are frequently under the scrutiny of their parents, sponsors, and those watching behind a screen. These child influencers currently lack federal protections that ensure their well-being and safety. Family vlogging has been proven to place a financial, mental, and sometimes, physical burden on children involved. Federal regulations have been encouraged by experts and survivors of child internet exploitation but have not been passed. This paper will examine the impact of family vlogging …

Automatic Generation Of Introductory Programming Exercises With Large Language Models, Nguyen Binh Duong Ta, Hua Gia Phuc Nguyen, Gottipati Swapna

Research Collection School Of Computing and Information Systems

Despite recent advances in code generation made possible by large language models (LLMs), programming is still an essential skill that computing students need to master now and in the foreseeable future. In learning programming, frequent practices with exercises set at an appropriate difficulty and knowledge level is of crucial importance for students. However, it’s not a trivial task for instructors to create many good quality exercises customized for each student. Programming problems found on Internet sources such as LeetCode are mostly too challenging for novice programmers with no prior coding knowledge. Recent work in AI-enabled education has been leveraging LLMs …

Generalization Bounds For Semi‑Supervised Matrix Completion With Distributional Side Information, Antoine Ledent, Mun Chong Soo, Minh Hieu Nong

Research Collection School Of Computing and Information Systems

We study a matrix completion problem where both the ground truth R matrix and the unknown sampling distribution P over observed entries are low-rank matrices, and share a common subspace. We assume that a large amount M of unlabeled data drawn from the sampling distribution P is available, together with a small amount N of labeled data drawn from the same distribution and noisy estimates of the corresponding ground truth entries. This setting is inspired by recommender systems scenarios where the unlabeled data corresponds to ‘implicit feedback’ (consisting in interactions such as purchase, click, etc. ) and the labeled data …
