From Fog To Function: An Occupational Therapist's Guide To Evaluating And Treating Cancer-Related Cognitive Impairments, Lauren E. Toner

Entry-Level Occupational Therapy Doctorate - Doctoral Capstone Symposium

Cancer – related cognitive impairment (CRCI) is a common side effect of cancer treatment that interferes with cancer survivors’ occupational performance, independence, and quality of life. Despite its high prevalence, CRCI remains under recognized and inconsistently addressed within oncology care. About 70% of individuals diagnosed with cancer report cognitive changes during or after treatment, yet many do not receive treatment. Occupational therapists are clinically trained to evaluate and treat functional cognition, activities of daily activities, instrumental activities of daily living, and client centered goals, positioning them as key providers in addressing CRCI. However, limited occupational therapy specific resources have hindered …

Practical Considerations For Conducting Canine Behavioral Science, Lucrezia Lonardo, Madeline H. Pelgrim, Jeffrey R. Stevens

Jeffrey Stevens Publications

Research on behavior in domestic dogs (Canis familiaris) has increased rapidly recently due to the interest in them as pets, working dogs, and model species for understanding evolution, domestication, and even human health. This interest in canine behavioral science has resulted in the creation of dozens of dog lab worldwide, with more starting every year. Our aim here is to review practical issues that potential dog researchers might consider when deciding how to set up a dog lab and conduct research in canine behavioral science. We hope that this can offer a path forward in promoting high-quality, cutting-edge …

A Stable Isotope Comparison Of The Biogenic Carbonate Of Mammalian Tooth Enamel From The Modern Ohio River Valley And Fort Ancient Buffalo Sites, Sara Elizabeth Slack

Theses, Dissertations and Capstones

δ¹⁸O and δ¹³C values change in response to anthropogenic factors (Ghosh & Brand, 2003). Little is known about the effects of anthropogenic climate and land use change on the ecology of the Ohio River Valley. The goal of this research was to quantify the effects of European colonization on the native ecology of the region. The specific questions of this research were: (1) How have mammalian tooth enamel δ¹⁸O and δ¹³C compositions shifted over time within the Ohio River Valley in response to anthropogenic climate change and vegetation? (2) Are there differences …

The Jevons Filter: Why Civilizations May Fail Before Reaching “Type I” Status, Giray Fidan

Comparative Civilizations Review

Humanity’s accelerating energy use poses profound questions about the long-term viability of technological civilization. This paper introduces the “Jevons Filter” hypothesis: a self-reinforcing feedback loop between efficiency improvements and rising aggregate consumption, rooted in the classical Jevons Paradox that systematically drives civilizations toward resource depletion and environmental thresholds. Here we argue that this feedback constitutes a critical developmental barrier, hindering sustainable progression toward Kardashev “Type I” energy mastery. We develop a simplified thermodynamic model linking energy efficiency, economic expansion, and civilizational dynamics, and engage with counterarguments regarding absolute decoupling and transformative technological innovations. Building on the classical Jevons Paradox, this …

Queer Experiences Of Double Disadvantage: The Moderating Effects Of Rejection On The Relationship Between Adverse Childhood Experiences And Attachment Style, Isabella Kinney

Psychology Honors Papers

This thesis examines how intersecting forms of disadvantage – particularly experiencing identity-based rejection and adverse childhood experiences (ACEs) – can negatively impact a queer-identifying individual. Previous research highlights that both ACEs and rejection are linked to poor mental health and insecure attachment patterns within LGBTQ+ populations. This study aimed to determine whether rejection serves as a moderator for the relationship between ACEs and attachment. Data was collected through an anonymous online survey of 81 participants recruited from Connecticut College and Connecticut’s LGBTQ+ Justice and Opportunity Network, and included measuring ACEs, rejection experience, and attachment patterns. Using a regression and moderation …

The English You Speak Matters: Immigrants, Phonological Roots, And Psychological Perspectives On Accent Discrimination, Sophia Hauschildt

Psychology Honors Papers

Accent serves as a highly salient social cue that influences how speakers are perceived, particularly in multicultural contexts where linguistic diversity is increasing. The present study examined how English accent affects evaluations of speaker warmth and competence, and how individual differences in cultural intelligence and colour-blind racial attitudes shape these perceptions. Using a between-subjects experimental design, participants (N = 225) were randomly assigned to listen to a standardised speech passage presented in one of five accents: General American English (GAE; control), Spanish-accented English, Chinese-accented English, Hindi-accented English, or Filipino-accented English. Participants then completed measures of speaker evaluation based on …

Deterrence Without Peace: Nuclear Weapons And The Rising Threshold Of Warfare, Catie Clarke

CISLA Senior Integrative Projects

Nuclear weapons fundamentally changed the international political landscape, leading to the emergence of deterrence theory and the notion of the Long Peace. This paper challenges these claims, arguing that nuclear weapons facilitated a more violent and volatile international system rather than stability. Drawing on constructivist theory, this paper develops the Threshold of Violence framework – a normative model which asserts that nuclear weapons elevated the perceived upper limit of tolerable violence in international politics. This raised threshold generated three trends in the nuclear era: increased frequency of proxy wars, escalating levels of benefactor involvement, and greater severity of conflicts fought …

The Information And Communication Behaviors Of Marcus Garvey And The Universal Negro Improvement Association (Unia), Janet Douglas-Pryce

Selected Full Text Dissertations, 2011-

Marcus Garvey, social activist and founder of the Universal Negro Improvement Association (UNIA) in the early twentieth century, has been widely studied for his Pan-African approach to the social upliftment of Black communities during a period marked by segregation and systemic injustice. His messages of empowerment attracted global attention and supported the growth of a movement that reached more than one million members worldwide. While Garvey and the UNIA have been examined from historical, political, and cultural perspectives, they have not been systematically studied through the lens of information and communication behavior. This study examines the information and communication behaviors …

Unveiling Microplastic Removal And Characteristics In Wastewater From Two Municipal Wastewater Treatment Facilities In Indonesia, Nurul Setiadewi, Prayatni Soewondo, Cynthia Henny

Applied Environmental Research

Wastewater treatment plants (WWTPs) are considered an entrance pathways for microplastic (MP) pollution in aquatic environments. This study reveals the removal and characteristics of MPs in wastewater from two municipal WWTPs in Indonesia. The influent contained 17.1 ± 5.65 particles L-1 (WWTP A) and 15.45 ± 4.31 particles L-1 (WWTP B), whereas the effluent contained 1.41 ± 0.01 and 1.5 ± 0.16 particles L-1. The removal efficiency was 91.75% for WWTP A and 90.32% for WWTP B, with no statistically significant difference (p > 0.05). WWTP A employed advanced treatment units, whereas WWTP B used a conventional pond-based system. MPs were …

Investigating The Viability Of Fully Online Asynchronous Physics Instruction In Formal Education, Clifton W. Massey-Noel

Physics Dissertations

In this dissertation we present results from two consecutive investigations into the fully online asynchronous modality in Physics Education. We first discuss the efficacy of a fully online asynchronous section of Modern Physics held in Fall 2024. The asynchronous section is compared with four prior partially-flipped sections of the same class, two of which were held in-person, and two of which were held synchronously online. Results suggest that all three modalities can be made to be about equally as effective. We also discuss the efficacy of a fully online asynchronous section of Calculus-Based Introductory Mechanics held in Fall 2025. The …

Innocence Interrupted: A 25-Year Study Of Reported Filicide Incidents In The United States, 1999 To 2023, Jeffrey A. Walsh, Jessie L. Krienert, Ema Voksic

Faculty Publications - Criminal Justice Sciences

This study examines filicide, the killing of a child by a parent or parental figure, using 25 years of data (1999–2023) from the National Incident-Based Reporting System (N = 3,974). Multinomial logistic regression was used to analyze variations in offender, victim, and incident characteristics across four victim age categories: neonaticide (within 24 hr of birth), infanticide (1–364 days), child filicide (1–17 years), and adult filicide (18+ years). Results reveal significant differences in offender age, sex, race, weapon use, and victim demographics. Neonaticide is most often associated with younger female offenders and the use of personal weapons, while adult filicide …

Reading Wars, Don Herzog

Books

Once again, we’re fighting wars over reading. Who gets to read? What do they get to read? These days, the right is obsessed with removing LGBTQ books from school and public library shelves and ensuring students read only the Correct version of American history. The left is obsessed with eradicating right-wing fantasies, not to mention outright lies, from the internet, and with airbrushing or even purging racist texts. You don’t have to stoop to whataboutery to notice a suspicious resemblance. But once again is wrong. We’ve always fought these wars, even if the enemies come and go. In this book, …

Spieltrieb, Edward F. Newcomb

College of Graduate Studies: Theses & Dissertations

This thesis investigates the creative and pedagogical intersections of nostalgia, play, and neurodivergent experience through a mixed-media studio practice. Grounded in Friedrich Schiller’s concept of Spieltrieb—the human drive to play as a balance between sensual and rational impulses—this work explores how childhood memory, instinct, and impulsive mark making inform both artistic production and art education.

Drawing on theoretical frameworks by Susan Sontag and John Berger, the work resists overinterpretation in favor of sensory immediacy, inviting viewers into direct, embodied encounters with material form. Sontag’s critique of mimetic representation and Berger’s analysis of reproducibility and context inform a practice that …

The Effect Of Complexity Of Expert Testimony And The Presence Of A Defensive Rebuttal On Jurors' Decisions In Criminal Trials, Shelby E. Madden

College of Graduate Studies: Theses & Dissertations

Forensic science plays a critical role in criminal trials, yet forensic techniques vary in their reliability. Expert testimony, often held in high regard by jurors, can be a decisive factor in verdicts, but its influence is complicated by factors such as technical complexity, adversarial bias, and heuristic processing. The present study examined how the complexity of prosecution expert testimony and the presence of a defensive rebuttal influenced jurors’ decisions when presented with faulty forensic evidence. Participants (N = 142) were randomly assigned to one of four conditions in a 2 (testimony complexity: high v. low) x 2 (defensive rebuttal …

Arts Cures: A Business Plan For Integrating Art As A Biometric Tool For Sensory Wellbeing In Commercial Ecosystems, Xinuo Zhang

Barriers To Mental Healthcare Among Men, Adrienne White

Murray State Theses and Dissertations

Men are consistently less likely than women to seek professional mental health services despite experiencing significant rates of depression and psychological distress. Traditional masculine norms and depression-related stigma have been proposed as major contributors to this disparity. The present study examined the relationships among depression stigma, conformity to masculine norms, depression severity, perceived barriers to care, and attitudes toward seeking professional mental health treatment among adult men with current or past depression. Seventy participants completed measures of depression severity (PHQ-9), conformity to masculine norms (CMNI-30), depression stigma (DSS), attitudes toward help seeking (MHSAS), and perceived barriers to care (BMHS). Contrary …

The Relationship Between Physical Activity, Sleep, And Hallucinations In Adults With Charles Bonnet Syndrome, Jarrod Hollis, Rohit Narayan, Eldre W. Beukes, Rosie Lindsay, Aliyah Bharwani, Umair Mughal, Ikra Yaqoob, Justin A. Haegele, Scott Muriden, Peter M. Allen

Human Movement Studies & Special Education Faculty Publications

Physical activity levels, hallucination experiences, sleep quality, and perceived stress were assessed using a survey administered to 57 adults with a confirmed diagnosis of Charles Bonnet Syndrome (CBS). Physical activity demonstrated a significant negative correlation with hallucination severity (r = –0.335, p = 0.011, two-tailed). A significant negative correlation was also observed between physical activity and perceived stress (r = –0.497, p < 0.001, two-tailed). In contrast, no significant association was identified between hallucination frequency and sleep disruption or insomnia. These findings suggest that engaging in appropriate levels of physical activity may help reduce the severity of hallucinations and mitigate stress among individuals with CBS. The observation that higher levels of physical activity are associated with reduced hallucination burden may help the development of evidence-based management strategies for CBS. Additionally, the finding that physical activity was significantly related to hallucination severity, whereas sleep disruption was not, merits deeper exploration in future research.

Association Between Internet Use For Health Information And Alzheimer’S Disease Diagnosis Among Older Adults With Diabetes In The United States: Examining Racial And Gender Disparities, Henry M. Zeidan

College of Graduate Studies: Theses & Dissertations

This study uses data from the National Health and Aging Trends Study (NHATS) Round 13, collected in 2024, to examine whether internet use for health information is associated with Alzheimer’s disease diagnosis among older adults with diabetes in the United States. Given the rising adoption of digital health, understanding who benefits from online health resources is increasingly important. The research also examines whether these associations differ across racial and gender groups, offering insight into potential disparities in digital health engagement and cognitive outcomes. Findings from this study will inform clinical practice, public health programming, and strategies to ensure equitable access …

The Psychiatric Burden Of Hidradenitis Suppurativa: A Trinetx Analysis Of Sex-Specific Disparities In Mental Health And Medication Use, Emily Sheetz, Julia Feord, Collette Sholi, Parker Adams, Tamas Gal, Susan G. Kornstein, Arturo Saavedra

Department of Medicine Faculty Publications

Background:

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition associated with physical and psychological burden. Prior research has shown increased rates of depression and anxiety among individuals with HS; however, sex-based disparities in the prevalence of these mental health conditions in patients with HS remain underexplored.

Objective:

To evaluate sex-based differences in the prevalence of major depressive disorder (MDD), generalized anxiety disorder (GAD), and the prescribing of antidepressants and anxiolytics among patients with HS.

Methods:

Using the TriNetX database, we identified patients over the age of 18 who had a recorded diagnosis of HS. Propensity score matching based on …

Examining The Physiological Stress-Reducing Effects Of Virtual Nature Exposure And Slow Breathing, Jesse Benefiel

Cal Poly Humboldt theses and projects

In a time of excess stress, it is essential to examine accessible stress-reduction methods. Research has demonstrated that virtual nature exposure and slow breathing can independently reduce stress, but the literature is lacking with regard to their combined effects. The present study aimed to replicate independent effects of breathing and nature on stress and to test for potential effects, including whether their combination would produce an interaction effect. Using a 2 Environment (Natural v. Control) by 2 Breathing (Slow v. Normal) between-subjects design, 63 participants completed a modified color-word Stroop task to induce stress and were then exposed to either …

Pretend Play Effects On Autistic Children's Theory Of Mind & Social Skills, Joelle Lok

Cal Poly Humboldt theses and projects

Autistic individuals often struggle with basic social skills due to deficits in Theory of Mind (ToM), perspective taking, reciprocity difficulties, etc. Early interventions that target these skills, specifically metarepresentation skills, could be essential to an individual’s social success and overall well-being. Further, pretend play shares an important relationship with ToM and social skills, due to their shared use of putting oneself in others’ shoes. Thus, a pretend play intervention could be beneficial in not only improving children’s overall play interactions, but also through a domino effect on their ToM and social skills. The directionality of the relationship between pretend play, …

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 …

Endocranial Lesions: A Paleopathological Study Of Late Medieval Skeletal Remains From Żelewo Poland, Francesca Aleen Meyer

Cal Poly Humboldt theses and projects

The site of Żelewo is located in a rural area of northwestern Poland, a region historically known as Pomerania. Skeletal remains from the cemetery associated with the archaeological site Żelewo 1-3, dating mostly to the 13th-15th centuries, are likely associated with a nearby Cistercian monastery. Numerous individuals from this site show evidence of endocranial lesions. To evaluate potential factors associated with the lesions, a differential diagnosis was performed based on macroscopic observations of endocranial lesion morphology and distribution. This study takes into account estimated age at death, biological sex, and other signs of pathology in the body. Potential confounding factors, …

Skeletal Markers: Interpreting Trauma, Healing, And Survival Through Osteological Remains From Medieval Pomerania, Michael Mulliner-Szyndler

Cal Poly Humboldt theses and projects

Traditionally, studies in bioarcheology have cited the presence of individuals with evidence of healed traumatic injuries and certain pathologies as an indication of social care either at the time of the trauma or throughout the individual’s lifetime. Here, I present three case studies of individuals who present with signs of having survived traumatic injuries and related pathologies. These individuals are from a late medieval cemetery in Żelewo, in the historical region of Pomerania in present-day northwestern Poland. The site is associated with the nearby town of Kołbacz, which is home to the oldest Cistercian monastery in Pomerania. This study aims …

Reward Deficits In Co-Occurring Social Anxiety And Depression: The Roles Of Anhedonia, Boredom, Loneliness, And Covid-19 Social Restriction, Nathan M. Hager, Alicia L. Milam, Hannah C. Hamrick, Benjamin Swanson, Matt R. Judah

Psychology Faculty Publications

Prior research points toward reward deficits as crucial to the link between social anxiety disorder and major depressive disorder. However, studies have not explored specific types of reward deficits or how social-environmental factors may impact them. The current study examined whether the indirect effects of three reward deficits (anhedonia, boredom, and loneliness) accounted for the connection between social anxiety and depression. Questionnaires were collected in a sample of college students (N = 523) during the first year of the COVID-19 pandemic, allowing examination of environmental stressors (i.e., remote learning and current friend network size) on reward deficits. Indirect effect models …

Responding To Suicide Loss: A Guide For Clinicians In Therapy With Suicidal, Grieving Adolescents, Brianna Jurosic

Psychology Doctoral Specialization Projects

Psychologists have spent years attempting to conceptualize what causes individuals to become suicidal and ultimately understand why individuals choose to die by suicide. Dr. Thomas Joiner (2005) developed the Interpersonal Theory of Suicide in an attempt to summarize and build upon previous models. The Interpersonal Theory of Suicide is built upon three factors: perceived burdensomeness, thwarted belongingness, and the acquired ability to enact lethal self-injury. Joiner theorized that perceived burdensomeness and thwarted belongingness together create the desire for suicide, and the ability to enact lethal self-injury adds the final piece that moves the desire toward action (i.e., a suicide attempt). …
