Helicobacter Pylori And Cancer: What's The Link?, Elettra Merola, Giovanni Mario Pes, David Yates Graham, Maria Pina Dore

Faculty, Staff and Students Publications

Helicobacter pylori (H. pylori) is a human bacterial pathogen that causes one of the most common chronic bacterial infections worldwide. The microorganism has been classified by the International Agency for Research on Cancer as a Group I carcinogen. While the etiological link to gastric cancer is well established, the precise molecular and cellular mechanisms driving this transformation are highly complex and incompletely understood. Fundamentally, the infection results from the chronic presence of acute on chronic gastric mucosal inflammation. H. pylori pathogenicity is increased by bacterial virulence factors including the cytotoxin-associated gene A (CagA) and Vacuolating cytotoxin A (VacA) …

The Development And Pilot Evaluation Of An Out-Of-Hospital Immersive Birthing Simulation Training Application For Paramedics And Ambulance Officers Using Virtual-Reality Technology, Michella Hill

Theses: Doctorates and Masters

Out-of-hospital births (OOHBs) are births which occur outside a hospital setting. This includes planned home births attended by midwives, or unplanned OOHBs where the intention was to birth in a hospital or maternity centre, however, occurs in an unintended location. Prehospital clinicians, inclusive of registered paramedics and volunteer ambulance officers (VAOs) infrequently attend OOHBs, as most births occur in maternity wards as anticipated. OOHBs comprises < 1% of emergency ambulance requests and requires specialised skills for prehospital clinicians to competently manage birthing and potential complications. As exposure to birthing is so rare, these specialised skills and knowledge are underutilised and subject to rapid decay. Compounding the problem, obstetrics is infrequently taught across undergraduate education, in-service training, or within individual clinician’s continuing professional development. Placements shadowing midwives are scarce due to nursing and medical students receiving priority. Previous research regarding OOHBs is limited, nonetheless suggests prehospital clinicians are underprepared to manage an OOHB, which has serious patient safety implications. The present research sought to explore prehospital clinicians’ preparedness and confidence in managing OOHBs. It also investigates whether a digital training solution such as virtual reality (VR) simulation may reduce the theory-practice gap and assist in competency retention.

Publication one provides a comprehensive methodology outline which is applied to Study One; a scoping review of prehospital clinician and birth parent experiences with OOHBs. Risk factors, complications and interventions provided by prehospital clinicians, as …

Getting Ready Right: The Impact And Influence Of The University Appointed Supervisor, Madlen Griffiths

Theses: Doctorates and Masters

Initial Teacher Education professional experience is a valued component of teacher education courses, where preservice teachers can practise applying what they have learned at university in classroom settings. Key to these experiences are supervisors, who are employed by the university and support these aspiring teachers during their professional experiences. This supervisory role is complex, underrated, under-theorised and under researched. Consequently, this research sought to address this shortfall through an investigation into the perspectives of two of the major stakeholders in these experiences: the preservice teachers and the supervisors.

Adopting a social constructivist methodology, this research examined the stakeholders’ perceptions of …

Injectable Borate/Borosilicate Bioactive Glass Systems For The Regeneration Of Hard Tissue – A Critical Review Of The Literature, S. Sina Mohammadi, Sunjeev S. Phull, Ryan J. Gilbert, Mark R. Towler

Chemical and Biochemical Engineering Faculty Research & Creative Works

Bone defects caused by trauma, infection, or tumor resection remain difficult to treat because successful repair requires both structural restoration and control of the local pathological microenvironment. Osteolysis, defined as pathological bone resorption, is central to many of these conditions and is commonly driven by excessive osteoclast activity. Clinically translated injectable products such as NovaBone® Putty demonstrate the value of moldable bioactiveglass grafts for defect filling; however, conventional silicate bioactive glasses are permanent and provide limited therapeutic ion release. This limitation has motivated the development of injectable borate bioactive glass (B-BGs) and injectable borosilicate bioactive glass (BS-BG) systems as more …

Fluid Dynamics Of A Microfluidic Micromixer–Micropump Driven By Adjacent Micro Synthetic Jets, Delara Soltani, Tim Persoons, Sajad Alimohammadi

Research Outputs: 2025-Present

Efficient mixing at the microscale remains a significant challenge in microfluidic systems due to the dominance of laminar flow and the consequent limitation of convective transport. Synthetic jets, generated by the oscillatory motion of a diaphragm within a cavity, produce a zero net mass flux while imparting periodic momentum to the surrounding fluid, thereby enabling localised flow perturbation and vortex generation that can substantially enhance mixing and mass transfer in microchannels. In this study, a pair of adjacent micro synthetic jets (AMSJs) is positioned perpendicularly to a microchannel to investigate their potential as a novel micropump-mixer. The vectoring effect of …

Podcasting emerged as the perfect format for highlighting educational content while being accessible and scalable.

On The Surface: The Mural Of Shireen Abu Akleh As Space For Encounter, Saja Abd El Hai

Dissertations and Theses @ UNI

This thesis examines a mural of Palestinian journalist Shireen Abu Akleh in the city of Baqa al-Gharbiya as a site of political encounter. Rather than approaching the mural solely as a commemorative image, the study analyzes how it generated a series of interactions through acts of creation, defacement, restoration, performance, and digital circulation. Drawing on scholarship in visual culture, graffiti studies, and political theory, I argue that the mural operates as a gendered space of political encounter through which grief, resistance, and national identity are negotiated in public space. Methodologically, the project combines visual and contextual analysis with rhetorical criticism, …

Two Cheers For Cox V. Sony, James Gibson

Law Faculty Publications

There’s a lot to dislike about the Supreme Court’s opinion in Cox Communications, Inc. v. Sony Music Entertainment. It mischaracterizes, oversimplifies, and ignores precedent. It fails to engage with important arguments. It mangles the meaning of “intent.” And it introduces uncertainty into the workings of secondary liability across other intellectual property regimes.

For these reasons, the decision doesn’t deserve three cheers. But it deserves two. Because in two important ways, the Supreme Court has succeeded. First, the opinion fixes some misguided appellate court holdings by articulating a relatively workable standard for future copyright cases involving secondary liability. Second, despite …

Dismantling The Whiteness Of Legal Education, Doron Samuel-Siegel

Law Faculty Publications

Whiteness is not merely a racial description. Whiteness operates as allegiance to structural racism. The quiet engine of racial hierarchy, whiteness pervades and shapes traditional legal education, rendering legal pedagogy a structurally racist enterprise. Legal education not only reproduces the racism embedded in the law and legal profession, but also obscures the ways legal doctrine, professional norms, and pedagogical practices normalize, protect, and make invisible the advantages that accrue to whiteness itself. In doing so, itproduces lawyers ill-equipped to dismantle structural injustice.

This Article breaks new ground in the scholarship on legal pedagogy by defining whiteness as it operates within …

The Middle Space: Redefining Collaborative Directing In Adaptive American Collegiate Theatre, Tyler J. Simons

Graduate Studies Theses and Dissertations 2026

This thesis examines collaborative directing as an adaptive, relational practice that exists between rigid hierarchical authorship and fully collectivized creation. Challenging dominant binaries in directing discourse that frame leadership as either singular or egalitarian, this study argues for a “middle space” in which authority, authorship, and responsibility are continually negotiated in response to institutional structures, pedagogical contexts, and interpersonal dynamics. Directing is framed not as a fixed methodology or ideological position, but as a responsive practice shaped by context. Grounded in a practice-as-research (PaR) methodology, the thesis analyzes four productions: Rhinoceros (Theatre UCF, 2024), The Tricks of Scapin (Freedom High …

Un Lugar A Donde No Puedo Volver: Perteneciendo En La Distancia, Alberto J. Alonso

Graduate Studies Theses and Dissertations 2026

“A Place I Cannot Return To: Distance and Belonging” investigates how home is not limited to a fixed place, but instead a reconstruction sustained through memory and longing, which focuses on personal experiences of being away from Puerto Rico. I contribute to this broader dialogue by offering a deeply personal perspective shaped by the complexities of cultural belonging. Through photography, collage, and painting, my art practice reconstructs fragmented visual narratives of lived experience to explore homesickness, nostalgia, and displacement, examining how personal and shared histories become anchors to what continually slips away. Although I can physically return to Puerto Rico, …

Critical Analysis Of Legal Education: Faculty Perspectives Of Law School's Role In Producing Practice-Ready Graduates, Sophia M. Akel

Graduate Studies Theses and Dissertations 2026

Legal education has long been the subject of harsh, widespread criticism due to concerns about its ability to adequately prepare students for legal practice. Newer attorneys have reported feeling incapable of performing even the most basic functions of their job after graduation from law school (Merritt & Cornett, 2020). Despite this troubling reality, law schools largely continue to function as they always have (Cramton, 1981). To gain insight directly from important figures in legal academia, this study examined law faculty perceptions on legal education’s role in producing practice-ready graduates. A mixed-methods survey design incorporating both quantitative descriptive and qualitative elements …

Passenger Pigeons, Dodos, Neanderthals, Jordan Alexander

Graduate Studies Theses and Dissertations 2026

Passenger Pigeons, Dodos, Neanderthals is a short story collection rooted in Afrofuturism and Southern literature. Passenger Pigeons centers the experiences of queer Black American women in various settings, from Mars to rural Florida. The title story of the collection follows Teri, a human on Mars, attempting to integrate into a society of Martians who exoticize and tokenize her. In this story, I use science fiction as a vehicle to confront the microaggressions and overt racism people of color often experience in professional environments. “Rather Be the Devil,” is a fabulist story detailing the character Man’s journey to find his missing …

Investigating The Association Between Polycystic Ovary Syndrome (Pcos) And Idiopathic Intracranial Hypertension (Iih): A Cross-Sectional Analysis, Savannah L. Adams

Graduate Studies Theses and Dissertations 2026

Polycystic ovary syndrome (PCOS) and idiopathic intracranial hypertension (IIH) are chronic conditions that disproportionately affect women of reproductive age and share several metabolic risk factors, including obesity, insulin resistance, and hormonal dysregulation. Despite growing clinical interest in a potential relationship between these conditions, limited research has examined awareness, knowledge, symptom presentation, and barriers to healthcare among young adult populations. The purpose of this study was to investigate awareness, knowledge, perceived healthcare barriers, and potential associations between PCOS and IIH among college-aged individuals. A cross-sectional survey was administered to students aged 18-25 at the University of Central Florida through classroom recruitment …

The Role Of Cultural Intelligence In Hotel Employee Engagement, Self-Efficacy, Job Satisfaction, Performance, And Intent To Stay, Meaad Eid F Almotairi

Graduate Studies Theses and Dissertations 2026

This research examined how Cultural Intelligence enhanced hotel employees’ engagement, self-efficacy, job satisfaction, performance, and intent to stay. CQ was defined as an individual’s capability to understand, adapt to, and work effectively in culturally diverse situations. This thesis utilized a quantitative methodology based on the Job Demands–Resources (JDR) model and self-efficacy theory. The study focused on the hospitality industry in Saudi Arabia, where increasing diversity has created a need for stronger cross-cultural skills among employees. Data were collected from hotel employees and managers to examine the relationships between CQ and key employee outcomes. The findings indicated that Cultural Intelligence significantly …

'But George Floyd Wasn't A Saint': A Critical Discourse Analysis Pre And Post George Floyd, Raya Berkley-Jacobs

Graduate Studies Theses and Dissertations 2026

May 25, 2020, George Floyd died at the hands of former police officer Derek Chauvin after he placed his knee on George Floyd’s neck for 8 minutes and 46 seconds. His death sparked outrage, protests, and calls for accountability, justice, and reform. This study addresses the impact of George Floyd’s death as a focusing event that created a policy window under which federal legislation was introduced as a response to his death. Drawing on Punctuated Equilibrium Theory and Social Construction Theory, the study utilizes a critical discourse analysis to test how the death of George Floyd impacted the amount and …

Exploring Governance And Government Policies Of Preparedness And Response To Flooding In Juneau, Alaska, Derreck Asiamah

Dissertations and Theses @ UNI

Flooding poses an escalating threat to human well-being, economic stability, and environmental resilience in climate-sensitive regions such as Juneau, Alaska, where the retreat of the Mendenhall Glacier has produced an actively expanding ice-dammed lake, Suicide Basin, capable of triggering an annual Glacial Lake Outburst Flood (GLOF). This thesis explores the governance and government policies shaping flood preparedness and response in Juneau, Alaska, with particular attention to GLOF risk and the August 2024 GLOF, one of the most destructive flood events in the city's history. Grounded in adaptive governance theory and political ecology, the study offers a multidimensional perspective on institutional …

Holographic Sensors For The Detection Of Volatile Organic Compounds, Graceson Antony

Doctoral

Volatile organic compound (VOC) monitoring at parts-per-million (ppm) concentration levels is essential for occupational safety, indoor air quality, and regulatory compliance. Although holographic gas sensors have been widely investigated, most operate in reflection mode as qualitative visual indicators, with limited quantitative evaluation of sensing mechanisms and scarce systematic demonstrations of repeatable multi-cycle validation for VOCs at ppm concentrations. A physics-based optimisation framework for transmission-mode holographic gas sensors which can bridge this gap has remained largely undeveloped.

This thesis presents the development and optimisation of real-time transmission-mode volume phase transmission holographic grating (VPTHG) sensors for ppm-level VOC detection. A comprehensive theoretical …

Following The Water: Tree Water Sources In Coastal Northern California Forests, Kaitlyn Briggs

Cal Poly Humboldt theses and projects

Increasing drought intensity and declining summer water availability in Mediterranean- climate forests raise concerns about forest resilience and streamflow persistence. This study evaluated how tree water sources vary with hillslope position, season, species, and watershed context across three coastal northern California forests. Stable isotopes of hydrogen (δD) and oxygen (δ18O), soil moisture time series, linear mixed-effects models, and site-specific Bayesian mixing models (MixSIAR) were used to estimate proportional contributions of shallow soil, deep soil, stream-associated, and fog water to tree xylem water. Across sites, xylem water isotopic signatures overlapped primarily with soil water, indicating dominant reliance on subsurface sources, while …

Subjective Glib Dynamics: Using An Alien Society To Investigate Reactions To Leader And Member Norm Deviance, Catie Burtch

Cal Poly Humboldt theses and projects

Social groups are built by members and leaders who form consensus on the defining attributes of their groups. Individual group members look to senior members and leaders to learn what it means to be a member of that group. Thus, norm maintenance is an important aspect of group health. The subjective group dynamics model details the specific group contexts under which people derogate ingroup members for transgressing norms. However, ingroup leaders are treated differently from regular group members and are given leniency for their transgressions. The current research extends these two bodies of work by directly comparing the consequences of …

Geographic Variation In Proteomic Responses To Ocean Acidification In A Cold-Water Coral (Balanophyllia Elegans), Keana A. Richmond

Cal Poly Humboldt theses and projects

In the face of a rapidly changing climate, assessing organismal responses to future stressors in the context of current, natural exposure to stress could provide key insights to understanding marine ecosystem resilience. I used Balanophyllia elegans, a cold-water, solitary, azooxanthellate coral as a model to better understand how varying oceanographic conditions across its geographic range have shaped its ability to tolerate and potentially adapt to current and future ocean acidification conditions. I collected B. elegans individuals from four sites across 2,500km of their range and subjected them to two pH treatments to investigate site-specific protein expression in response to …

Coho Salmon (Oncorhynchus Kisutch) Response To Habitat Restoration Through Space And Time: Monitoring Growth, Survival, And Movement In A Restored Habitat Network, Carter Perez Adamson

Cal Poly Humboldt theses and projects

Despite the decline of coho salmon (Oncorhynchus kisutch), Prairie Creek, a tributary of Redwood Creek in northern California, remains a coho salmon stronghold. The restoration of juvenile coho rearing habitat was identified as a recovery objective in this watershed by the National Marine Fisheries Service. Among the restoration projects addressing this objective are an ongoing project on Prairie Creek and its tributary Skunk Cabbage Creek, and a prior effort on Strawberry Creek (a tributary of Redwood Creek’s estuary). Standard monitoring methods for assessing project success have limitations and may be improved by measuring salmon use of restored habitats …

Repairing Estranged Death: Care, Politics And Ecology In The Us Funeral Industry, Cecilia Catherine Rodriguez

Cal Poly Humboldt theses and projects

The industrialization of death practices in the US has separated humanity from natural cycles while centering white settler colonial norms that marginalize other cultural ways of caring for the dead. Through necropolitics, the contemporary death industry embodies capitalist values of commodification and a monopolization of care, separating death from community and its ecological cycles. Black and Indigenous feminist knowledges understand death as not a discrete event but instead as an ongoing process that shapes our relationships with both the human and more-than-human worlds. Engaging with feminist political ecologies, I extend a conversation about care and repair to contemporary death practices …

Decolonizing Restorative Justice: A Teaching Development Project, Lacy Felice Mitchell

Cal Poly Humboldt theses and projects

The coloniality of power serves as a central axis within the matrix of domination that characterizes global capitalist modernity, as Anibal Quijano famously argued. This power is rooted in particular ways of looking, seeing, and understanding social reality, anchored in Eurocentrism as an epistemological paradigm for the hegemonic discourse produced by the West against both internal and external categories of “other.” Such categories still inform the production of knowledge in educational settings. In this project, I engage in a critique of the coloniality of power to explore its implications and potential for critical pedagogical practice within the context of sociology …

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 …

Reclaiming Presence: An Anthropological Study Of Digital Disconnection And Meaning-Making, Leslie De Paz

Cal Poly Humboldt theses and projects

Human attention is increasingly at risk in an unregulated digital ecosystem where overconsumption shapes neurological function, social interaction, and the ways people make meaning of everyday life. Dominant discourse around digital overuse tends to medicalize the problem, framing it as individual addiction or clinical dysfunction. In this thesis, I argue that such framing obscures what a cultural phenomenon is fundamentally, one in which people are actively questioning their relationship with technology, building awareness, and developing practices that help them slow down and reclaim agency within algorithmically mediated environments. This study draws on 22 semi-structured interviews with Gen Z and millennial …
