Using Vegetation Communities To Compare Natural And Constructed Wetlands In The Red River Basin In Texas And Louisiana, Kennedi K. Davis
Using Vegetation Communities To Compare Natural And Constructed Wetlands In The Red River Basin In Texas And Louisiana, Kennedi K. Davis
Biology Theses
Wetland vegetation provides an abundance of ecosystem services such as water quality regulation, flood control, and it provides habitat space for fish, amphibians, and macroinvertebrates. Not only that, but these plants also act as excellent indicators of wetland conditions as dominant vegetation types are often used as biological criteria for classifying wetlands and other habitats (Cowardin and Golet, 1995). This project will assess the structure of vegetation communities to determine how they differ in constructed and natural wetlands within the Red River drainage basin to see if Agricultural Conservation Easement Program – Wetland Reserve Easement (ACEP-WRE) constructed wetlands are effective …

Pomona Faculty Publications and Research
Aryl alkyl sulfones are an important class of compounds in drug discovery; thus, new methods toward their synthesis are desirable. A general sulfur fluoride exchange (SuFEx) method to couple aryl sulfonyl fluorides with alkyl carbon pronucleophiles to make aryl alkyl sulfones is described. The reaction was applied to a diverse set of pronucleophiles, including esters, amides, heteroarenes, nitriles, sulfones, sulfoxides, and sulfonamides, at room temperature under mild conditions. We highlight the application of this transformation in parallel medicinal chemistry for the high-throughput generation of a broad array of aryl alkyl sulfones. Lastly, we apply this method to the late-state SuFEx …

Biology Faculty Works
Most multicellular life reproduces sexually, utilizing a single-celled stage that acts as a genetic bottleneck. This bottleneck limits the evolution of selfish cell adaptations by ensuring all cells descend from a single progenitor. We investigated an obligately asexual strain of Schmidtea mediterranea planarians that reproduces by self-bisection and lacks a single-cell bottleneck. Using 2.5 yearlong data on planarian reproductive behavior combined with genotyping, we revealed two previously undescribed genetically distinct substrains within the CIW4 strain. One substrain showed reduced fitness, which correlated with substantial losses of heterozygosity and increased somatic diversity. By genotyping consecutive head offspring over multiple generations, we …

Pilot Fatigue And Required Rest Period For Korean Air Force Pilots Flying High-Performance Aircraft, Mijin Hong
Graduate Thesis and Dissertation post-2024
Over the years, significant advancements have been made in aircraft technology and in understanding the detrimental effects of fatigue on flight performance. However, integrating these advancements into crew rest regulations, particularly for the Republic of Korea Air Force (ROKAF) operating high-performance jets, requires further review. This study employs a systematic review with thematic analysis to assess whether ROKAF’s current rest regulations are sufficient. Relevant studies were identified from English-language databases (e.g., FAA, ICAO, Google Scholar) and Korean-language databases (e.g., RISS, KCI). Titles and abstracts were initially reviewed, followed by full-text assessments based on inclusion and exclusion criteria focusing on military …
Tail-Imbalance Diffusion Equalizer For Class-Balanced Generation, Chinmay Dhanraj Nehate
Tail-Imbalance Diffusion Equalizer For Class-Balanced Generation, Chinmay Dhanraj Nehate
Graduate Thesis and Dissertation post-2024
Real-world image corpora are often imbalanced. On long-tailed datasets, the head class can outnumber the tail by a large margin, and a vanilla diffusion probabilistic model (DPM) consequently loses fidelity and diversity on rare categories, undermining controllable generation. To address this gap, we present Tail Imbalance Diffusion Equalizer (TIDE), a training framework that restores class balance without discarding data or adding extra training stages. Our contribution is threefold: (i) score field rebalancing, where we embed class-prior knowledge into a mixing matrix that routes gradients toward minority classes, with this class-prior knowledge consisting of the empirical label frequencies in the training …
Sex Estimation Using Linear And Geometric Morphometric Analyses Of The Adult Human Talus, Melissa N. Marks
Sex Estimation Using Linear And Geometric Morphometric Analyses Of The Adult Human Talus, Melissa N. Marks
Graduate Thesis and Dissertation post-2024
Estimating biological sex is an essential first step when analyzing human remains in both forensic and archaeological contexts. While the pelvis and skull are traditionally used for this purpose, they are not always present or sufficiently preserved to permit analysis. The talus is sexually dimorphic and can yield highly accurate sex estimates, making it a promising alternative skeletal element for sex estimation. As there is currently no accepted protocol for sex estimation using the talus, the present study attempts to replicate and validate existing methods using linear and three-dimensional landmark data, while comparing data from ancient Maya (n=16), ancient Egyptian …
Differential Interferon Synthesis And Signaling Between Parainfluenza Virus Acute And Persistently Infected Cells, Vonisha Kaigler
Differential Interferon Synthesis And Signaling Between Parainfluenza Virus Acute And Persistently Infected Cells, Vonisha Kaigler
Graduate Thesis and Dissertation post-2024
RNA virus infections can transition from an initial acute infection to a prolonged or persistent infection, in which infected cells survive and continue to produce progeny virus. This presents a major clinical problem as persistently infected (PI) cells extend viral shedding, maintain inflammation, and provide potential sources for new viral variants. The RNA virus, Parainfluenza virus 5 (PIV5), with mutations in the P/V gene region (P/V mutant) is a strong inducer of antiviral responses. Interestingly, over time, there is an emergence of cells that survive as P/V mutant PI cells. Given that changes in innate immune signaling pathways can occur …

'How To Mother': Televisual Reimaginings Of Black Matriarchy In The Real Housewives Of Potomac, Kalijah Rahming
Graduate Thesis and Dissertation post-2024
Since the initial launch of The Real Housewives of Orange County in 2006, Bravo’s The Real Housewives franchise has soared to previously unimaginable heights. With 11 American installments, 30 international adaptations, and 25 current spin-offs, it is clear that even viewers who are relatively unfamiliar with The Real Housewives franchise may find themselves inadvertently swept up in their world due to the popularization of their catchphrases and gifs on social media platforms like Instagram, Twitter, and Facebook. In addition to carefully shaping popular culture, members of this franchise have even altered the conditions of the entertainment industry’s practices for the …
A Forgotten Kairos: Rhetorical Memory In 16th Century Europe, Phillip Martin
A Forgotten Kairos: Rhetorical Memory In 16th Century Europe, Phillip Martin
Graduate Thesis and Dissertation post-2024
In 16th century Europe the nearly 2000-year-old discipline of rhetoric, still a pillar of education, underwent significant change. One of the more curious changes occurred in rhetoric’s subdivision known as memory, memoria, that is, memory’s “artificial” cultivation. During the 16th century rhetorical memory was paradoxically both maximized and marginalized as a discipline. And by the early 17th century memoria was all but extinct as a branch of rhetoric. The causal mechanisms of this transformation remain underexamined, particularly by rhetoric and composition scholars, and most explanations remain unclear and uncompelling. Accordingly, this thesis attempts a new approach …
A Community-Based Wellness Program To Increase Exercise Adherence For Menopausal And Postmenopausal Women: A Mixed-Methods Pilot Study, Kristin M. Badillo
A Community-Based Wellness Program To Increase Exercise Adherence For Menopausal And Postmenopausal Women: A Mixed-Methods Pilot Study, Kristin M. Badillo
Graduate Thesis and Dissertation post-2024
Evidence exists that long-term commitment to an exercise routine is beneficial. Contrarily, there is a notable lack in exercise adherence among menopausal and postmenopausal women. Though research has thoroughly examined the reasons why menopausal and postmenopausal women may not be committed to an exercise routine, it remains unclear what motivates those who are adherent. This pilot study employed a mixed-methods design through administering surveys and conducting in-person focus group interviews. Additionally, an 8-week buddy system was implemented to assess the role of social support and its effect on exercise adherence. For quantitative data collection, a total of 7 participants enrolled …
Predicting Past And Future Anthropogenic Global Harvest And Land Use, Michelle Bardales Cruz
Predicting Past And Future Anthropogenic Global Harvest And Land Use, Michelle Bardales Cruz
Graduate Thesis and Dissertation post-2024
Anthropogenic appropriation of natural lands has long sustained human populations and activities. Human use of the environment has resulted in the degradation of green spaces and depletion of natural, particularly plant-based, resources. Human appropriation of net primary production (HANPP) is a globally available, spatially explicit measure of this human-driven extraction and diversion of plant biomass through harvesting (HANPPharv) and land use change (HANPPluc). Models for HANPP have been limited temporally (e.g., a year) or in terms of complexity (e.g., one predictor). In this study, I predict HANPPharv and HANPPluc from 1960 to 2010 at …

Instructional And Motivational Factors Predicting Deep Learning Approaches In Pre-Clinical Medical Students, Kenneth L. Dearman
Instructional And Motivational Factors Predicting Deep Learning Approaches In Pre-Clinical Medical Students, Kenneth L. Dearman
Graduate Thesis and Dissertation post-2024
Pre-clinical medical students predominantly employ surface learning approaches, focusing on memorization and exam preparation rather than developing a deep understanding of medical knowledge. This study employed a correlational design comparing two courses with different instructional approaches using expectancy-value theory to examine how instructional methods and motivational factors predict deep learning approaches among 148 pre-clinical medical students at a College of Medicine in the Southeastern United States. Initial results showed that the three separate constructs in task motivation (expectancy beliefs, values, and cost) did not mediate the relationship between active instructional methods and deep learning strategies. Instead, active learning was a …
Investigating The Role Of Selenium-Dependent Stickland Reactions In Clostridioides Difficile Bioenergetics, Dominika Dzurny
Investigating The Role Of Selenium-Dependent Stickland Reactions In Clostridioides Difficile Bioenergetics, Dominika Dzurny
Graduate Thesis and Dissertation post-2024
Clostridioides difficile is an anaerobic, spore-forming bacterium and one of the leading causes of antibiotic- associated diarrhea. Colonization depends on the metabolism of certain nutrients in the host gut, namely amino acids and carbohydrates. C. difficile ferments amino acids as an integral part of its metabolism via Stickland reactions, utilizing the selenoproteins D-proline reductase (Prd) and glycine reductase (Grd) to generate energy. Specificity of selenocysteine incorporation reflects the intracellular levels of selenophosphate, the activated selenium donor synthesized by selenophosphate synthetase (SelD). SelD is coincidentally a selenoprotein itself, containing a UGA codon at position 17 (Sec-17). The functional and physiological importance …
Interactions Of Anti-Viral Ceria Nanoparticles With An Enveloped Rna Virus, Muhammad Hassan Mehmood Kalyar
Interactions Of Anti-Viral Ceria Nanoparticles With An Enveloped Rna Virus, Muhammad Hassan Mehmood Kalyar
Graduate Thesis and Dissertation post-2024
There is growing interest in developing durable and broad-spectrum antiviral nanomaterials for surface disinfection. Silver-modified ceria nanoparticles (AgCNPs) are regenerative materials capable of inactivating a wide range of viruses through generation of reactive oxygen species (ROS). We hypothesized that for enveloped RNA viruses, the lipid bilayer and viral spike glycoproteins are determinants of sensitivity to inactivation of infectivity by AgCNPs. This hypothesis was tested using Vesicular Stomatitis Virus (VSV), a model enveloped negative-sense single strand RNA virus containing a single spike glycoprotein G. Five rounds of serial passage of VSV in the presence of suboptimal AgCNP concentrations led to the …
Exploring The Role Of Fatty Acid Signaling In Macrophages, Ayomide Ogunsanmi
Exploring The Role Of Fatty Acid Signaling In Macrophages, Ayomide Ogunsanmi
Graduate Thesis and Dissertation post-2024
Dietary fatty acids play critical roles in both the gustatory and immune systems. In taste, they serve as the sapid molecules that underlie the ability to taste fat, whereas in the immune system, they serve as messengers that help facilitate the fuel-based reprogramming of macrophages (MΦ) that underlie optimal immune function. It has become clear in recent years that there is a functional interaction between the taste and immune system, and fatty acid signaling pathways serve as one focus of this overlap. Similar to taste receptor cells (TRCs), MΦ express G protein-coupled fatty acid receptors GPR120 and GPR84, and our …

One of the challenges in developing and archipelagic countries such as Indonesia is maintaining energy demand in rural and isolated areas due to difficulties in electrical distribution. For instance, in areas like Bawean Island, no additional electricity capacity has been introduced in the past year, leading to an unmet potential customer demand. One of the possible options is by utilizing Hybrid Renewable Energy Systems (HRES) that are integrated with existing fossil fuel-based energy systems to support the growing energy demand in the remote island. A case study in Bawean Island is conducted with the projected energy demand covers the energy …
Seating Charts, Connections, And Fostering Community, Mckenna B. Chow
Seating Charts, Connections, And Fostering Community, Mckenna B. Chow
Theses and Dissertations
This thesis explores how fostering stronger connections in the high school ceramics classroom can create a more inclusive and collaborative community. I regularly changed seating charts to encourage new relationships and strengthen classroom culture as part of this effort. Historically, seating charts have enforced uniformity and promoted specific behaviors. My research challenges these traditional purposes and proposes that seating arrangements can instead serve a more meaningful and enduring goal: promoting connection and ensuring that all students feel seen. I found that while seating charts can contribute to this goal, achieving genuine connection and inclusivity also requires several additional factors to …
