Bacterial Community Function In Pitcher Plant Leaves As An Experimental And Mathematical Model Of Functional Dynamics, Amelia Jackson

Cal Poly Humboldt theses and projects

This work looks at two different sites with differing abiotic factors in measures of altitude, temperature and precipitation. The site with higher altitude, larger temperature range, and lower precipitation, located in Plumas National Forest (Quincy, CA), had a flat BEF trend that suggests functional redundancy The site with lower altitude, more moderate temperatures, and higher precipitation located in Six Rivers National Forest (Gasquet, CA), also had a flat BEF trend. These abiotic factors could correlate to the significantly different bacterial compositions between sites. The second portion of this work is modeling the host antagonist relationship between Eyxra moths and their …

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, …

Nutrient-Driven Transcription Factor-Dna Interactions And Their Signaling Mechanisms In Metabolic Disease, Evelyn A. Bates

Theses and Dissertations--Nutritional Sciences

Metabolic homeostasis is maintained through tightly coordinated signaling networks that integrate diverse physiological inputs. Central to this regulation are transcription factors, which sense nutrient, hormonal, and vitamin-derived signals and translate them into coordinated gene expression programs. Transcription factor activity is governed by DNA binding, recruitment of coregulatory proteins, and interactions with specific response elements in gene promoters, which allows them to selectively modulate diverse metabolic pathways. Owing to their multifactorial and tunable nature, transcription factors have emerged as promising targets for the treatment and diagnosis of metabolic diseases, including metabolic dysfunction-associated steatotic liver disease (MASLD). This dissertation explores the molecular …

Vegetation Species And Bed Position May Drive Epifaunal But Not Nekton Habitat Use In Estuarine Submerged Vegetation In The Mobile-Tensaw River Delta, Alabama, Steven Vroljik, Kathryn O'Shaughnessy, Ashley Mcdonald, Zoey Hendrickson, Bethany Kiley, Anna Reimer, Sierra Robertson, Samantha Smith, Edward Sullivan, Charles Martin

Gulf and Caribbean Research

Submerged aquatic vegetation (SAV) supports nekton and epifaunal macroinvertebrates, sustaining food webs and ecosystem services in estuaries. Invasive SAV can alter these dynamics by displacing native vegetation and restructuring communities. In Alabama’s Mobile-Tensaw Delta (MTD), Eurasian milfoil (Myriophyllum spicatum) is rapidly expanding and outcompeting native wild celery (Vallisneria americana). This study compared nekton and epifaunal assemblages between M. spicatum and V. americana, focusing on edge versus interior positions. Nekton surveys identified 22 taxa (M. spicatum, n = 13; V. americana, n = 18), but assemblages did not differ significantly between vegetation types …

Prevention Beyond Deterrence, Benjamin A. Barsky

Emory Law Journal

This Article reconceptualizes preventive justice—the public safety paradigm that seeks to prevent harm before it occurs. Scholars have long documented how cities have advanced this paradigm through largely punitive measures, notably variants of broken windows policing, which posit that aggressive misdemeanor enforcement deters more serious crime. Yet in the aftermath of the 2020 George Floyd protests, and as underscored recently in City of Grants Pass v. Johnson, these measures have faced a legitimacy crisis—prompting calls for nonpunitive responses to nonviolent incidents.

This Article establishes a preventive justice approach that advances health and safety without emphasizing crime deterrence. It draws …

Lunch Shaming And The Right To Privacy, Ira P. Robbins

Emory Law Journal

Lunch shaming is the practice of penalizing students who cannot afford to pay for their meals, resulting in them being denied food, served alternative meals, or publicly identified. The origins of lunch shaming can be traced to the financial pressures faced by school districts that struggle to balance tight budgets with the mandate to provide free or reduced-price meals to eligible students. Despite legislative efforts and advocacy campaigns aimed at mitigating the problems associated with lunch shaming, the practice persists, exacerbated by rising food costs and the expiration of pandemic-era food programs.

Many law journal and other articles have correctly …

Beyond Ssris: Omega-3 Fatty Acids And The Neurobiology Of Impulsivity In Borderline Personality Disorder, Sujean Doo

Scripps Senior Theses

Impulsivity is a central and clinically significant dimension of Borderline Personality Disorder (BPD), and is strongly associated with self-harm, aggression, and suicide risk. Despite its prognostic importance, pharmacologic management of impulsivity in BPD remains inconsistent. Selective serotonin reuptake inhibitors (SSRIs) are frequently prescribed; however, randomized controlled trials demonstrate limited efficacy for impulsive-aggression, and some patients experience a paradoxical behavioral activation. Meta-analytic and systematic reviews further suggest that mood stabilizers and second-generation antipsychotics may outperform antidepressants, yet no specific medication is indicated to target impulsive behavioral dyscontrol.

This thesis synthesizes findings from systematic reviews, randomized trials, and neuroimaging research to evaluate …

The Effects Of The Opioid Crisis On Contraceptive Decisions And Fertility In Pakistan, Simren R. Khan

Scripps Senior Theses

This paper examines how the opioid epidemic influences household fertility behavior in Pakistan by analyzing contraceptive use and fertility outcomes across regions with differing levels of opioid prevalence. Using household-level data from the 2017–18 Pakistan Demographic and Health Survey (DHS) and estimating OLS regression models, the study compares households in high-prevalence regions with those in low-prevalence regions. The results show that exposure to high-opioid regions is associated with lower fertility outcomes and a higher likelihood of respondents wanting their last child. These patterns suggest that households may respond to opioid-related economic and caregiving burdens by limiting family size and treating …

An Analysis Of Eating Disorders As A Comorbidity Of Autoimmune Diseases, Madeleine Shore

Scripps Senior Theses

For many autoimmune disease patients, psychiatric conditions are a common comorbidity. Although there are many shared mechanisms between autoimmune disease and psychiatric conditions, current research surrounding mental health among autoimmune disease patients often focuses on mood disorders rather than eating disorders. Despite the high risk for developing psychiatric conditions, most autoimmune disease patients are not screened for eating disorders. This lack of screening is significant, because if an eating disorder is missed by a healthcare provider, the autoimmune or eating disorder condition could be exacerbated, resulting in severe illness or even fatality. Given an existing link between comorbid psychiatric disorders, …

The Effect Of Sleep Environment On Sleep Quality And Behavior In Firefighters: A Cross-Sectional Study, Jacquelyn N. Zera, Erica Esper, Anna Peluso Simonson, Ashley N. Clausen, Serena Paterno

2026 Faculty Bibliography

Firefighters face high-stress occupational demands and irregular shift work that negatively impact sleep quality, which is intrinsically linked to long-term physical and psychological health. This cross-sectional study examines how the physical sleep environment (home vs. work) and station sleeping arrangements (bunk-style vs. individual dorm-style quarters) influence subjective sleep quality in this population. Sixty-six career firefighters (Age = 40.89 ± 11.05 years), completed the Pittsburgh Sleep Quality Index (PSQI) to assess their sleep in both home and fire station environments, with data analyzed using Wilcoxon Signed Ranks and Mann–Whitney U tests. The results reveal significant differences (p < 0.001), with sleep duration, efficiency, subjective quality, and global PSQI scores all performing significantly better at home than at work. Notably, no significant differences were found between bunk-style and dorm-style sleeping quarters at the station. These findings suggest that firefighters experience poorer sleep while on duty regardless of room design, indicating that operational stressors like call volume and nocturnal arousal may be more influential on sleep quality than the physical arrangement of sleeping quarters, and could inform organizational policies and wellness programs aimed at reducing occupational fatigue.

Dietary Intake And Predictors Of Healthy Eating In Midwestern American College Students: An Observational Study †, Anna Peluso Simonson, Jacquelyn N. Zera, Gregory S. Farnell

2026 Faculty Bibliography

College students often maintain poor dietary habits, notably low fruit and vegetable intake. Commonbarriers include limited time, cost, and lack of nutritional knowledge. This study examined dietary behaviors, barriers, and factors influencing Healthy Eating Scores (HES) amongcollege students. Participants (N = 224; age = 20.3 ± 2.5 years, BMI = 23.9 ± 4.1 kg/m2, 78.9% female, and 91.3% white) completed an online survey. Results indicate meat overconsumption with underconsumption of water, fruits, and vegetables. Limited time and healthy options were the primary perceived barriers. Tests of between-subject effects identified gender (F = 4.38, p = 0.04) and living situation (F …

"It's A Dance": Examining Midwives As Choreographers Of Reproduction In Maine, Annie Goldstein

Honors Theses

This thesis examines the contemporary work of community-based Maine midwives through the theoretical framework of choreography. In the context of this work, choreography can be understood as the well-thought-out, purposeful undertaking of a process during which negotiation, coordination, and improvisation are required to adapt to constantly changing circumstances. Using choreography, this thesis attempts to understand how Maine midwives navigate global market processes and practice under authoritative forms of biomedicine, ultimately linking them to other midwives across various global sites. Situated within Maine’s maternal health landscape that is characterized by the ongoing closure of labor and delivery units and rural hospitals, …

Ultra-Processed Or Ultra-Addictive? A Demand-Based Redefinition Of Ultra-Processed Foods, Braden Jondro

Honors Theses

Ultra-processed foods now comprise the majority of the U.S. food supply and have been directly associated with 32 chronic diseases including obesity, cardiovascular disease, cancer, and diabetes. Current classification systems such as NOVA provide a useful framework for identifying food processing, but rely on broad and subjective categorizations that may not capture the mechanisms most closely associated with promoting persistent overconsumption. In particular, existing classification systems remain limited in their ability to evaluate addiction-like behaviors associated with highly processed foods, including persistent purchasing patterns, reinforcement effects, and substitution responses. This paper introduces the Ultra-Processed Food Intensity (UPFI) index, an objective, …

Why Stay? A Qualitative Case Study Of Parents Who Choose Local Public Schools Over Alternative Options, Michael Antonio Scott

Theses and Dissertations

Public schools face challenges that directly impact the quality of education and educational programming. Declining student enrollment trends affect school funding and resource allocation for school improvement. This qualitative case study identified key factors influencing parents' perceptions of school quality and explored how these perceptions shaped school choice decision-making. Guided by Rational Choice Theory, the study examined how individuals make enrollment decisions by weighing perceived costs, benefits, constraints, and available resources to achieve desired educational outcomes. Semi-structured interviews, an open-ended survey, and archival school performance data were used to explore the perspectives of parents with children enrolled in public high …

Meconium Metal Concentrations And Infant Temperament And Development, Fiona Fogarty

Dissertations and Theses

BACKGROUND: Prenatal exposure to metals poses significant health consequences for early childhood development. Understanding the factors influencing metal concentrations that infants are exposed to in-utero is crucial for developing targeted interventions, particularly when maternal characteristics and environmental factors, may contribute to varying levels. Meconium offers insight into in-utero exposures for the developing infant, and the effect of each individual metal may be mediated or exacerbated by another and therefore should be studied in the context of a mixture. The effect of metal mixture exposure, as measured in meconium, on milestone and temperament outcomes has yet to be determined.

An Engine, Not A Vessel: Place, Politics, And Health In The United States, Philip B. Rocco

Political Science Faculty Research and Publications

Social scientists often treat places as containers for social and economic phenomena that shape health outcomes. Yet this analytic practice conceals more than it reveals. Local governments in the United States should be understood as engines of both health promotion and stratification. As the contributions to this symposium suggest, governments not only occupy a formal place in the U.S. public health system, their decisions on everything from housing to transportation infrastructure can also have profound impacts on health outcomes. Local political economies likewise renegotiate the parameters of acceptable health interventions, public understandings of health disparities, and the status of population …

Economic Exchange And Relational Work In Doubled-Up Households, Hope Harvey

Sociology Faculty Publications

Doubling up, or sharing a home, is an increasingly common way that families make ends meet. Drawing on over 170 in-depth interviews with 60 parents, I ask how doubled-up household members understand and contest their economic relationships. I show that the success of intra-household economic exchange depends not only on the amounts exchanged, but also the shared meanings behind these exchanges. Given the lack of institutionalized expectations guiding doubled-up household relationships, household members draw on competing norms, framing the household as either a solidarity unit or a series of independent nuclear family units. Although disagreement over economic relationships is common, …

Perceived Adolescent Insecure Attachment With Mothers And Fathers, Helena Pipová, Martin Dolejš, Jaroslava Suchá, Alexander T. Vazsonyi

Sociology Faculty Publications

The aim of this study was to test relationships between adolescent insecure attachment (anxious and avoidant) with mothers and fathers and three outcomes: food addiction, eating disorders, and weight status, in a large multi-regional sample of Czech adolescents. Anonymous, self-reported data were collected from 3,677 adolescents (1,688 boys, 45.9% and 1,989 girls, 54.1%). Both anxious and avoidant attachment with mothers were positively associated with food addiction (p <.001) and eating-disorder risk (p <.001). Importantly, avoidant attachment with fathers uniquely and additively explained variance in both food addiction (p <.001) and eating-disorder risk (p =.003), after controlling for maternal attachment. Weight status was unrelated to attachment and was predicted by sex and parental education only. Study findings highlight the salience of insecure attachment with both mothers and fathers for food addiction and eating disorders among adolescents and identify the parental relationship as a key potential preventative strategy.

Fda After Loper Bright, Erika Lietzan

Faculty Publications

Loper Bright, which overruled the Chevron decision from 1984, tells us that a court should determine the meaning of all statutory provisions for itself, rather than deferring to the views of the federal agencies that implement those provisions. But the overruling of Chevron may have less of an impact on the U.S. Food and Drug Administration than conventional wisdom supposes. Most challenges to FDA action do not concern its statutory interpretations. And the agency prevailed in most cases involving statutory interpretation, before the Chevron doctrine took hold. After 1984, when the doctrine did apply, the agency often lost cases at …

The Suppression Of The Opelousas Massacre Of 1868: The Blackleg Hunt Or “La Chasse A’ La Jambe Noire”, August Malveaux

The Griot - Southern Conference on African American Studies, Inc.

This article examines the suppression of the 1868 Opelousas Massacre—also known as “la chasse à la jambe noire” or the Blackleg Hunt—and situates it within the broader landscape of Reconstruction-era racial violence in Louisiana. Malveaux argues that the massacre was not an isolated riot but a premeditated act of political terrorism designed to eliminate Black electoral participation and reverse Reconstruction gains. Triggered by Black political mobilization and white supremacist resistance, the violence unfolded over several days in September 1868 and resulted in widespread murder, intimidation, and property destruction. The essay challenges the historiographical minimization of the event, emphasizing how organized …

Ai-Driven Risk Forecasting For Strengthening The United States Food Supply Chain Resilience: Case Study: A National Ai-Enabled Food Supply Chain Risk Forecasting Framework And A Data Analytics Approach To Predicting Disruptions, Sarah Onyeche Usoro, Itua Austin Omogiate, Rahab Zhewe Felix, David Azikutenyi Galadima

Student Publications

The United States food supply chain is one of the most complex and interconnected systems in the world, spanning agricultural production, processing, transportation, storage, and retail distribution. While this complexity enables efficiency and scale, it also increases vulnerability to disruptions caused by climate change, labor shortages, geopolitical shocks, transportation failures, cyber threats, and public health crises. Conventional risk management methods, often reactive and siloed, have proven inadequate in predicting and mitigating systemic shocks that have become frequent occurrences in today’s world. This article examines how artificial intelligence (AI) and data analytics can transform risk forecasting in U.S. food supply chains …

Themes were identified using thematic analysis with a directive and deductive approach based on SCT. Focus groups revealed eight major themes across the SCT. Cognitive themes included: (1) improved nutrition literacy, (2) understanding the nutrition-mental health connection, and (3) increased awareness of …

Soil Nutrient Sufficiency Versus Plant Nutrient Status In Compost-Amended Soils: Plant Tissue Analysis As A Diagnostic Tool, Chandralekha Joga Miss

Murray State Theses and Dissertations

This study evaluated whether Mehlich III soil nutrient sufficiency ratings reliably predict plant nutrient status and chlorophyll response across contrasting compost application histories. A greenhouse pot experiment was conducted with Chijimisai (Brassica rapa) planted in three treatment soils that had no compost (T1), moderate compost history (T2), and long-term hog manure compost application (T3). Plant performance was assessed through weekly shoot length and chlorophyll content (SPAD) measurements, leaf number at maturity, and leaf tissue nutrient analysis conducted at harvest. Soil test results indicated adequate to high nutrient levels across all three treatments. Leaf tissue analysis, however, revealed substantial …
