Effects Of Energetic State On Male Mating Preferences In Poeciliid Fishes With Differing Mating Strategies, Katherine E. Taylor

Theses

Reproduction is energetically costly, making condition (i.e., energetic state) a potential factor in shaping reproductive behavior. However, its role in male mate choice remains largely unexplored. Here, we investigate condition-dependent effects on male mate choice in two species of Poeciliids: one coercive species (Gambusia affinis) and one courting species (Xiphophorus hellerii). Diet treatments were used to manipulate male and female conditions, and male preferences were assessed in dichotomous-choice tests using animated female stimuli. X. hellerii males showed a preference for high-condition females, whereas G. affinis males showed no overall net preference. Diet influenced preference in G. affinis, with high-fed males …

Reflux Micro-Aspiration: Natural History, Pathophysiology, Clinical Presentation And Treatment, Oleksandr Khoma

Theses

Background

The accurate diagnosis of gastro-oesophageal reflux pulmonary micro-aspiration has only become possible recently with the introduction of a novel technique of reflux micro-aspiration scintigraphy study combined with single photon emission computed tomography (SPECT) combined with x-ray tomography (CT) in a hybrid instrument (1-3). This has allowed the accurate diagnosis of pulmonary and airway contamination with refluxate. Previously only patients with large volume symptomatic reflux aspiration were diagnosed clinically (Mendelson syndrome) or by 2-dimentional barium meal or an older plantar (2 dimensional) technique of scintigraphic aspiration studies. The concept of reflux micro-aspiration has been implicated in multiple pulmonary diseases but …

Optimisation Of Sampling For A New Skin Microbiome Assay Pilot Study, Anita Smith

Theses

Recent interest in the diverse ecosystem of bacteria, fungi and viruses that make up the skin microbiome has led to numerous studies investigating the microbiome in healthy skin and in dermatological diseases. An imbalance of the normal skin microbial flora can cause some skin diseases, and current culture techniques are often unable to detect a microorganism to further our understanding of the clinical–microbiological correlates of disease and dysbiosis. Atopic dermatitis and rosacea are presentations that General practitioners (GPs) often manage that may have an infective or microbiological component and can be challenging to treat. Further research using culture-independent techniques is …

Visible And Invisible Empires: The Revival Of The Ku Klux Klan 100 Years Ago, Christian Molina

Theses

Hatred and violence breed division, and division breeds more hatred and more violence. In an America where our politics has become name-calling, finger-pointing, scapegoating, and whataboutisms, and violence, unfortunately, it is safe to say our nation has entered this self-perpetuating cycle. A place for malicious groups concerned with growth, power, and profit to capture the angry, the stressed, and the less informed in their webs of elaborate lies and misleading, misinterpreted numbers the way they have in decades past.

A Search For Serotyping Candidates In The Streptococcus Sobrinus Genome, Ryan Schwendel

Theses

Streptococcus sobrinus (SSO) is a pathogenic microbe native to the human oral microbiome. SSO is historically implicated in carie formation, and may be involved in neurodegenerative disease progression. The study of SSO is challenged by a lack of access to a serotyping assay. This study aims to identify sero-specific candidates from available SSO genomes using sequence alignment and phylogenetic analysis. Three candidate genes were found that may be sero-specific: putative quinol monoxygenase, a hypothetical protein, and elongation factor Tu. To further assess the candidates the original antibodies or a list of proteins involved is required. Alternatively, a new classification system …

Understanding Crime Through Harm: A Multi-Stage Study Of Rochester, Ny, Hayder Alhafedhi

Theses

This capstone project develops, critiques, and applies a Crime Harm Index (CHI) for the City of Rochester, New York, as an alternative to traditional crime measures that rely solely on raw counts. Rather than treating all offenses as equal “one crime = one unit,” the project weights crimes by the severity of harm they cause, using New York State sentencing guidelines as the core metric. Across four working papers, the project moves from conceptual foundations and limitations of harm-based metrics, to the construction of a Rochester-specific Crime Harm Index, and finally to a set of spatial regression models that link …

Understanding The Relationship Between Mental Health And Criminal Justice Involvement: Pathways, Disparities, And Improving System Responses, Haley Bly

Theses

This capstone project examines the complex relationship between mental health and involvement in the criminal justice system, emphasizing how pathways, external conditions, structural inequities, and system responses interact to shape long-term outcomes for persons with mental illness (PwMI). While mental illness alone is not a predictor of criminal behavior, the intersection between psychological disorders, social strain, stigma, and systemic failures significantly heightens the risk of criminal justice involvement. Combining four working papers, this capstone examines these relationships across individual, environmental, institutional, and community levels, ultimately arguing that treatment and rehabilitative-centered reforms are essential for improving the experiences of individuals with …

The briefly independent Republic of Yucatán requested foreign intervention to end the Caste War. The United States debated intervention in Yucatán, while Mexico, still reeling from the loss of the Mexican-American War and dealing with internal political conflict, made steps to reincorporate Yucatán back into Mexico and to diplomatically resist American expansion. Examining the political landscape of the United States and Mexico in the spring of 1848 offers an alternate perspective …

A Comparison Of Fixed And Repetitive Models During Imitation Training In Children With Developmental Delays In A School Setting, Laci Fletcher

Theses

Imitation training is commonly recommended in applied behavior analytic literature to address deficits in imitative skills. Few studies have directly compared imitative models to identify the most efficient and effective teaching arrangement to facilitate imitative skills (Deshai & Vollmer, 2019; Halbur et al., 2023). Previous results are inconclusive, and the authors recommended further research comparing the effect of fixed and repetitive models. Therefore, the present study was a replication of Halbur et al. (2023) and addressed limitations suggested by the authors. We examined whether components of imitative models affected the efficiency of the model type and reduced faulty stimulus control …

This thesis propose a built-in sen- sor to detect delayed hazards and a sensor to diagnose circuits in the presence of those hazards resulting reliable detection. This thesis intends to propose 2 sensors for non-robust test-based monitoring and test- ing. The first sensor discussed is for IC testing with NR tests. This sensor is capable of detecting any full-swing …

Relationship Between Semi-Aquatic Mammal Occupancy And Particulate Carbon, Nitrogen, And Phosphorus Dynamics In Freshwater Ecosystems, Madison H. Stokoski

Theses

Semi-aquatic mammals such as beavers (Castor canadensis) and muskrats (Ondatra zibethicus) can influence carbon (C), nitrogen (N) and phosphorus (P) dynamics in freshwater systems. While the effect of beavers, in particular, are typically attributed to their dam and lodge building behaviors, these animals do not always build these structures. It’s possible that other, non-damming behaviors (e.g. foraging and burrowing) may influence the availability of nutrients as well. To assess this possibility, we surveyed 54 lentic and lotic waterbodies across Southern Illinois and investigated the possibility that beaver and muskrat occupancy improved our ability to explain variation in nutrient availability across …

Massive Stars Behaving Badly: Exceptional Interactions And Their Remnants, Kaila Nathaniel

Theses

Massive stars are some of the most dynamic and influential objects in the Universe, driving galactic evolution through violent explosions and serving as progenitors to neutron stars and black holes. While the evolution of isolated massive stars already produces remarkable phenomenae, massive stars that interact with companions or evolve within extreme environments may produce even more extraordinary outcomes. In this dissertation, I investigate some exceptional circumstances in which a massive star might find itself. In a first investigation, I analyze the strong interactions between isolated pairs of stars in low-density environments. If a binary consisting of a massive star and …
