Inflammatory Bowel Disease (IBD) is a group of chronic gastrointestinal disorders, including Ulcerative Colitis and Crohn’s disease. As of 2020, it was estimated that IBD significantly impacts the lives of approximately 2.39 million Americans. Magnesium (Mg) is an essential mineral involved in many bodily functions, including immune response and gut health. Recent studies suggest that Magnesium levels may be linked to IBD. Therefore, this review aims to explain how Magnesium might play a role in the development or progression of IBD. Additionally, this article discusses the overall role that Magnesium’s plays in gut health and whether Magnesium supplementation could be …

Starch-based bioplastics are promising sustainable alternatives to petroleum-based plastics; however, their limited mechanical strength and stability restrict broader packaging applications. This study investigates the influence of polyvinyl alcohol (PVA) content on the structural and functional properties of starch-based bioplastic films reinforced with chitosan and microcrystalline cellulose (MCC). Films prepared by solution casting with varying PVA compositions were characterized in terms of density, mechanical properties, thermal stability, biodegradation behavior, antibacterial activity, and structural features. Increasing PVA content produced denser film structures with improved tensile strength and thermal stability, while elongation at break reached its maximum at the intermediate formulation, indicating a …

Wet tropical forests are experiencing rising temperatures and increased frequency and intensity of extreme climatic events, such as cyclones, which can increase rates of soil erosion and surface runoff. Fungal litter mats, formed by agaric decomposer fungi, play a crucial role in stabilizing slopes, preventing erosion, and aiding nutrient cycling; however, little is known about how warming affects litter mat growth and function. We investigated two litter mat-forming fungi, Gymnopus johnstonii and Marasmius aff. crinis-equi, in warmed (+4°C above ambient) and control plots in the Luquillo Experimental Forest, Puerto Rico. Growth and time-to-leaf colonization were monitored over 6 weeks …

Per- and polyfluoroalkyl substances (PFAS) occur as complex mixtures, yet mixture-dependent biological effects under environmentally realistic exposure conditions remain poorly understood. We conducted multiyear (2018, 2019, 2021) continuous-flow, field-based exposures of male fathead minnows (Pimephales promelas) using a low-PFAS reference well (REF; sum of measured PFAS (∑PFAS) 0.1–0.2 μg L–1) and PFAS-contaminated groundwater from a fire-training area (FTA) at Joint Base Cape Cod, Massachusetts. Dilution treatments enabled separation of concentration and mixture effects. Groundwater from well FTA1 was perfluorooctanesulfonate (PFOS) dominated (∑PFAS 10–31 μg L–1), whereas groundwater from well FTA2 had higher concentrations and …

Methane (CH4) is a potent greenhouse gas, and tropical forests account for roughly one–third of global atmospheric CH4 uptake by soils. Projected warming and more frequent hurricanes in these ecosystems may alter soil CH4 sink strength, as warmer and wetter soils enhance methanogenesis activity. We measured soil CH4 and CO2 efflux during the calendar summer months of 2023 and 2024 alongside continuous records of soil moisture, soil and air temperature, and precipitation in an in–situ warming experiment (TRACE) located in a lowland tropical forest in Puerto Rico, six to seven years after Hurricanes Irma …

INTRODUCTION: Cannabis use is proliferating among oncological populations. However, research is limited on whether cannabis routes and sources are associated with neighborhood disadvantage and whether it moderates the relationship between neighborhood disadvantage and patient-reported outcomes (PROs). This analysis evaluates the relationship between neighborhood disadvantage and cannabis source and route, and their association with PROs.
METHODS: Analyses included 106 patients with cancer from varying levels of neighborhood disadvantage. Logistic regressions tested the association of neighborhood disadvantage with cannabis source (i.e., regulated vs. unregulated) and route (i.e., inhaled vs. consumed/other formulations). Multilevel regressions tested the association of neighborhood disadvantage with PROs (e.g., …

Non-heme Fe(II)/2-oxoglutarate (2OG)-dependent halogenases catalyze highly selective C-H halogenation. BesD is a non-heme Fe(II)/2OG halogenase that performs regio- and stereoselective chlorination of the l-lysine (l-Lys) substrate. Understanding the mechanism by which halogenation is favored over canonical hydroxylation is essential for guiding enzyme engineering efforts aimed at converting hydroxylases into halogenases. Here, we combine molecular dynamics (MD) and hybrid quantum mechanics/molecular mechanics (QM/MM) calculations to elucidate the origin of chlorination selectivity in BesD and variants derived from a homologous hydroxylase. Our results indicate that, although the initial inline Cl-Fe(III)-OH intermediate is inherently predisposed toward hydroxylation, it undergoes a two-step isomerization in …

Improving Human-Wildlife Coexistence: An Ecological And Educational Approach To Rewilding Grizzly Bears (Ursus Arctos Horribilis) In California, Amanda C. D. Rosales
Master's Projects and Capstones
Megafauna extinction during the Holocene has been both caused and amplified by climatic changes and human influence. By the last half century, large carnivores were diminished in Europe and the United States, but policies increasingly addressed species decline and their territories expanded. This research examined large carnivore rewilding across the European Union and United States, specifically for rewilding brown bears, Ursus arctos, in historic habitat. Next, case studies for the health status of climate-impacted whitebark pine, Pinus albicaulis, a high energy food for bears, was assessed. Ultimately, research case studies, human perspective surveys, and the California Department of Education content …

UNL Faculty Course Portfolios
Social and emotional factors are critical for learning, being core aspects of the educational psychology curricula. Recently, neuroimaging has emerged as a powerful tool to comprehend the neurobiological factors underlying these factors. Yet, many educational psychologists have low familiarity with neuroscience research. The course EDPS 991: Social and Affective Neuroscience, from the Department of Educational Psychology at the University of Nebraska-Lincoln, emerges in this context, training educational psychology graduate students to consume, conduct, and disseminate findings about how the brain relates to socioemotional processes. One challenge related to the course is that many students feel anxious about learning the neuroimaging …
Climate-Driven Maritime Hazards And Marine Fuel Oil Spill Risk In The Northwest Passage, Emily Grace Parker
Climate-Driven Maritime Hazards And Marine Fuel Oil Spill Risk In The Northwest Passage, Emily Grace Parker
Master's Projects and Capstones
Shipping activity across the Northwest Passage has increased by 46% since 2011 as climate forcing drives sea ice decline, but associated risks to vessels and the environment are underestimated and rarely examined together. A literature review conducted in this study indicated that by 2070, a 5-month navigation window will expose vessels to increasingly unpredictable hazards as the region transforms from an ice- to wave-dominated regime, with wave heights increasing by 10-13% per decade. Ice hazards persist, and vessels operating in early summer and late fall will be exposed to elevated ice accretion risk that can cause capsizing and marine fuel …

The Role Of Intermittent Nutrient Loading In The San Francisco Bay, Rebecca M. To
Master's Projects and Capstones
A harmful algal bloom in 2022 shattered the illusion that the highly enriched San Francisco Bay is resilient to eutrophication. This event provided justification for the San Francisco Water Board to issue restrictions on nitrogen in wastewater effluent, the largest source of nitrogen in San Francisco Bay. Recognizing San Francisco’s fragile status even with this recent regulation, this study analyzes other anthropogenic sources of nutrient pollution, and it examines nature-based solutions to drawdown nutrient loading. This research utilizes a nutrient budget review to account for nitrogen inputs, a relative source contribution to quantify sanitary sewer overflows, a geospatial analysis to …
Photocatalytic Advanced Oxidative Processes (Aop) As A Promising Agricultural Runoff Treatment Solution For The California Central Valley, Briana Miller
Master's Projects and Capstones
Pesticide pollution in the California Central Valley (CV) is a major concern for aquatic toxicity. This research will determine if photocatalytic advanced oxidation processes (AOP), an emerging water treatment technology, could be implemented within the CV to degrade pesticides. A case study, literature review, comparative analysis, and policy analysis were conducted to identify pesticides of concern within the CV, if photocatalytic AOP can degrade those pesticides, how photocatalytic AOP compares to current technologies, and regulatory challenges with implementing photocatalytic AOP. Between 2019 and 2023, the top 30 most applied pesticides were identified, with 12 chemicals identified as aquatic toxicants, seven …

Master's Theses
Historically, Tijuana has been the destination for migrants who have been left out from the United States, Mexico, and the rest of the world. The city is at the epicenter of globalization where many transit, leave, and arrive. Sometimes considered a “third country” due to its binational and bicultural identity with its sister city, San Diego, California. The growing number of Haitian refugees that arrived in Tijuana in the mid 2010s to seek asylum in the United States overwhelmed the city’s infrastructure and left the Haitian community vulnerable, yet it created new opportunities and reshaped new identities in the region. …
Linking Fishery Productivity To Child Health In The Coastal Tropics, Francisco Flores-Mejia
Linking Fishery Productivity To Child Health In The Coastal Tropics, Francisco Flores-Mejia
Master's Theses
Fish are a primary source of calories, macronutrients, and income for coastal communities around the world, but overfishing and environmental changes have dramatically reduced productivity in the majority of small-scale fisheries. The social costs of these losses are believed to be large, particularly in poorer communities, but most estimates of fishery productivity effects on households are contextual and difficult to generalize. We combine a remote sensing measure of pelagic fishery productivity with geolocated child health and growth data from 34 countries in the coastal tropics. We estimate that the difference between sustainedly good versus bad fishing conditions corresponds up to …
The Feather Of The Quill: How Folklore Shapes Human Relationships With Wildlife, Taylor Breeanne Nelson
The Feather Of The Quill: How Folklore Shapes Human Relationships With Wildlife, Taylor Breeanne Nelson
Master's Theses
This thesis examines how folklore and cultural phenomena shape human relationships with wildlife, arguing that the stories a society tells about animals are not merely reflective of its values but are constitutive of them. Drawing on narrative research methods sourced from literature and academic journals and interviews with academics, conservationists, and community members, this project examines the role of animal folklore.
I discuss how narratives around wildlife evolved alongside the development of the United States, arguing that the beginnings of mainstream American conservation not only displaced existing communities but also erased the sophisticated human-animal relationships their traditions had long sustained. …
Examining The Ligands, Location, And Function Of Toll-Like Receptor 10, Kiefer Keanu Tam
Examining The Ligands, Location, And Function Of Toll-Like Receptor 10, Kiefer Keanu Tam
Master's Theses
Toll-like receptors are a class of innate immune pattern recognition receptors that detect pathogen-associated molecular patterns and regulate downstream inflammatory responses. Toll-like receptor 10 remains the only human TLR whose ligand specificity, cellular localization, and immunological function are not fully defined. Emerging evidence suggests that TLR10 may play an anti-inflammatory role and can heterodimerize with TLR2 to modulate immune signaling. Previous studies from our laboratory demonstrated that stimulation with heat-killed Mycobacterium tuberculosis promotes TLR2-TLR10 heterodimerization and trafficking to the cell surface. In this study, we expanded our ligand panel to include additional gram-positive bacteria, particularly anti-inflammatory probiotic species, to further …

Structure And Diversity Of Play Behavior In Juvenile Belding's Ground Squirrels, Paul O'Driscoll Ii
Master's Theses
Play behavior is ubiquitous among juvenile mammals and can promote motor, social, and cognitive development, providing multiple adaptive benefits to young animals in some cases. The structure of play can be linked to the benefits it confers on individuals. I evaluated the structure of play in juvenile Belding’s ground squirrels (Urocitellus beldingi), a species for which multiple adaptive benefits of play have been identified. I compared juvenile play in U. beldingi to adult sexual and aggressive behavior to determine and classify similarities between juvenile play and adult behavior. I evaluated diversity in the behaviors expressed during play interactions and diversity …

Investigating Cryptic Diversity In The Hawaiian Endemic Plant, Psychotria Mariniana (Rubiaceae), Uyen Thi Hoang Nguyen
Master's Theses
Islands, with their isolation and steep environmental gradients, serve as natural laboratories for studying speciation. Molecular phylogenetic and population genetic methods utilizing Next-Generation Sequencing (NGS) have revolutionized our ability to document patterns of genetic divergence and diversity. Cryptic diversity, genetically distinct populations that were previously unrecognized as unique, and cryptic speciation, where divergent genetic populations may be deserving of status as unique species, have been observed in many taxa. The Hawaiian Islands provide an ideal setting for studying divergence and speciation due to their extreme isolation, known ages, and volcanic origin. Previous work has investigated the evolutionary relationships of the …

Cucumber (Cucumis sativus L.) damping-off, which is caused by the soilborne oomycete Pythium aphanidermatum, is an extremely damaging disease. An environmentally friendly and safe method of controlling damping-off in cucumber and other vegetable crops is biological control, which employs naturally existing antagonistic microorganisms. In this investigation, bacteria from root tissues (endophytic bacteria) and rhizosphere soil (rhizosphere bacteria) were isolated from Tamarix nilotica (Tamaricaceae), commonly known as salt cedar, and their potential to inhibit P. aphanidermatum and their efficacy in managing damping-off in cucumber under controlled glasshouse conditions were assessed. Ten rhizospheric and six endophytic bacteria with different morphological traits were …

Journal of Agricultural and Marine Sciences
Oman's fisheries sector, deeply rooted in coastal tradition, is becoming a key pillar in the nation's transition away from oil dependency. With over 3,165 km of coastline and access to three major marine ecosystems, the Arabian/Persian Gulf, Sea of Oman, and Arabian Sea, the country holds vast ecological and economic potential. However, the sustainability and performance of small-scale fisheries (SSF), which represent over 90% of national fishing activity, vary widely across governorates due to environmental stress, infrastructure gaps, and climate vulnerability. This study presents the first governorate-level, multidimensional assessment of fisheries and coastal resources sustainability in Oman. Using a mixed-methods …

Gender Affirming Rhetoric, Emerson R. Wright
Tennessee Journal of Race, Gender, & Social Justice
During the runup to the 2024 election, virtually every person who watched an American football game saw an advertisement alleging that Kamala Harris was “for they/them,” while “President Trump is for you.” Candidates and interest groups spent more than $200 million on ads shaping and preying on public perception of trans people, and Democrats wasted no time blaming Kamala Harris’s electoral loss on messaging around trans issues. On the heels of a contentious election that relied heavily on this type of weaponized culture war messaging, misleading and hostile discourse about transgender people and the issues they face is hard to …

In a culture where convenience replaces process, this project argues that making — even when inefficient, imperfect, or unnecessary — enables forms of engagement that buying cannot.

However, this convenience proposes a mode of engagement based only in deeper knowledge of context and thus our experience with the world around us is hence diminished. Our engagement with the world becomes heavily mediated, regulated and controlled.
This project investigates how hands-on engagement with water can reintroduce + restore our sense of joy, curiosity, consequence, and …

Masters Theses
A Pot of Gold at the End of the Assembly Line integrates icons of mass-manufacturing with signifiers of joyful work, stimulating a dialogue between industrial and craft labour. Visible traces of the making process left on these works conjure a spectral ‘maker’, implied by the fingerprints, toolmarks, assembly, and conspicuous decision making of an ‘other’. As we relate to these signifiers as opportunities for our own bodily action, this spectre speaks in our own voice. Possessed by this ghost, viewers are vicariously thrust into an imaginary context and made sensitive to the nature of this work — whether it validates …

"Hand And Mind Lead To Life": Craft Pedagogy In Art Education For Older Adolescent Learners, Katherine Fu
Masters Theses
Art educator Jo-Anna Moore (1991) asks “What is the purpose of our individual growth through art or craft?” (p. 162). Moore’s question is daunting not least for the seasoned artist, but for the young people in our art classrooms who, to varying degrees, are or are not interested in art. This thesis draws from my personal narrative as an older adolescent whose introduction to craft helped me navigate great questions of identity, belonging, and motivation. It seeks to discover how craft can become a method of teaching art to all students, and in particular, how such a pedagogy addresses the …
