Predicting Capture And Survival Probabilities Of The Arizona Tiger Salamander: A Comparison Of Capture-Recapture Models, Brittney Nelson

Murray State Theses and Dissertations

Capture-recapture models are essential tools for estimating population dynamics in ecological studies. A fundamental component of these models is the capture history matrix, which records individual detection over time and serves as the basis for estimating survival and capture probabilities. This presentation explores three statistical approaches to these estimations: the Cormack-Jolly-Seber (CJS) model, the Hidden Markov Model (HMM) for CJS, and the Bayesian CJS model. The CJS model provides a likelihood-based framework for estimation, and the HMM CJS incorporates latent states into the model to account for uncertainty in detection. The Bayesian CJS extends this same analysis by integrating prior …

Through a detailed analysis of AI-generated imagery, the research uncovers implicit and explicit biases within these systems. The research also gathered …

Bending But Not Breaking: An Investigation Of The Relationship Between Psychological Flexibility And Suicidality In Individuals With Chronic Pain, Adalyn Mcmurray

Murray State Theses and Dissertations

Chronic pain is a burdensome condition that has been found to be associated with increased suicide risk, yet the mechanisms underlying this relationship remain unclear (Domenichiello & Ramsden, 2019). The present study aimed to examine the role of pain interference and psychological inflexibility in predicting past two-week suicidal thoughts among individuals with chronic pain, with psychological inflexibility explored as a potential moderator. This study also sought to replicate and extend McCracken et al. (2018) and enhance the understanding of suicidality in chronic pain populations by using the Multidimensional Psychological Flexibility Inventory (Rolffs et al., 2018b), a more psychometrically sound measure …

Equine Hair Cortisol Concentration And The Effects Of Season, Storage Method, And Personality Traits, Savannah M. Rivers, Grace A. Robertson, Thomas Powell, Lydia O'Sullivan, Shea Porr

Murray State Theses and Dissertations

Stress exists everywhere, for survival, adaptation is necessary. These adaptations directly reflected the stresses the animal experienced and demonstrated the ability to cope. An animal that could not cope could not survive. Stressful experiences resulted in behavior patterns for each animal. Consistent behavior can be defined as personality [1]; therefore, stress could directly influence personality by changing behavior.

Stress research helped analyze and identify animal personality traits, especially horses. Human-horse pairings partially relied on personality traits and, when considered, often led to improvements in welfare [2]. There are various tools to assess personality, one being Equine Personality Assessment [3]. The …

Understanding Bird Diversity: A Modeling Approach In An Urban And Wetland Ecosystem, Clay Bliznick

Murray State Theses and Dissertations

The global increase in anthropogenically-driven shifts of land cover has resulted in losses to many natural communities such as prairies and wetlands. These ecosystems take on artificially-derived characteristics such as croplands, buildings, and roads to the extent that they no longer resemble the areas they once were. This process often results in the loss of biodiversity, ecological integrity, and valuable ecosystem services in these environments. Attempts to restore the condition and function of these disturbed areas are often implemented, but due to the complexity of factors driving these restorations, there is often a lack of practical insight needed to optimize …

New Psychoactive Substances Detected In Wastewater Samples Collected Along The Interstate Highway Rest Areas In Kentucky, Durga Prasad Kodati

Murray State Theses and Dissertations

The rapid emergence and proliferation of new psychoactive substances (NPS) pose significant challenges to public health and law enforcement. The potential for abuse and toxicity of these substances, which are intended to mimic the effects of controlled drugs, has been raising concerns as these compounds are designed to evade being regulated. There are traditional methods of tracking NPS, such as seizures and forensic toxicology, but they are delayed and seldom effective because these substances continue to evolve rapidly. Wastewater-based epidemiology (WBE) has emerged as a promising tool for real-time surveillance of drug consumption. The primary objective of this research was …

Understanding The Influence Of Team Identifications Influence On Perception Of States, Morgan Elizabeth Macke

Murray State Theses and Dissertations

Team identification refers to an individual’s psychological connection to a team or athlete (Wann, 2006a), while rival salience involves awareness of a prominent rival team (Wann & James, 2019). This study examined the relationship between sport team identification and perceptions of a state housing a salient rival, specifically whether identification with the University of Kentucky (UK) men’s basketball team influenced perceptions of Tennessee, home to rival team University of Tennessee (UT). It was hypothesized that greater team identification would be associated with more negative evaluations of Tennessee, and that this relationship would be mediated by perceptions of the rival team. …

The Role Of Adverse Childhood Experiences On Aggression And Substance Use In Young Adulthood, Sadie Goralski

Murray State Theses and Dissertations

Adverse childhood experiences (ACEs) are widespread within the United States. More than half of the population has experienced at least one adverse event during their youth. Such experiences range from parental divorce to sexual assault. Past research has shown that adverse experiences during the formative years play a major role in the development of multiple physical and mental health issues. The current study aimed to explore the interplay among ACEs and two of these covariates: aggression and substance use. Moreover, the proposed study further investigated the development of substance use in emotionally dysregulated individuals with past adverse experiences. In doing …

Instantaneous Hydrolysis Of Methyl Paraoxon Nerve Agent Simulant Is Catalyzed By Nontoxic Aminoguanidine Imines, Emmanuel Kingsley Darkwah, Puspa Aryal, Chi Zhang, Charles B. Musgrave, William A. Goddard, V. Prakash Reddy

Chemistry Faculty Research & Creative Works

Exposure to organophosphate-based nerve agents and pesticides poses health and security threats to civilians, soldiers, and first responders. Thus, there is a need to develop effective decontamination agents that are nonhazardous to human health. To address this, we demonstrate that instantaneous hydrolysis of methyl paraoxon (Me-POX), a nerve agent simulant, can be achieved in the presence of aminoguanidine imines at pH 10: ● the pyridine-4-aldehyde aminoguanidine-imine (1) and ● the 2,3-butanedione aminoguanidine-imine (2). The hydrolysis of Me-POX under these conditions is substantially faster than that of the state-of-the-art decontaminating agent, Dekon-139 (2,3-butanedione oxime, potassium salt). Furthermore, Dekon-139 shows adverse effects …

Tricatalytic Organocatalyst-Enzyme Hybrid Cascade For Improving Complete Oxidation Of Glucose To Carbon Dioxide, Adam Milam, Rokas Gerulskis, Jose Intano, Shelley D. Minteer

Chemistry Faculty Research & Creative Works

Advancing energy harvesting is crucial for the development of wearable and implantable technologies. Given the high concentration of complex fuels, such as glucose, in biological fluids, biofuel cells present a promising avenue for exploration. However, glucose fuel cells that have been published to date typically catalyze only one or two of the maximum 12 oxidation steps for glucose, resulting in low energy density. Although known multienzyme cascades, which are sequential biochemical reactions where multiple enzymes work in tandem to convert a substrate into a final product, have addressed this inefficiency, they come with several trade-offs, such as reduced power density …

Understanding The Influence Of Image Enhancement On Underwater Object Detection: A Quantitative And Qualitative Study, Ashraf Saleem, Ali Awad, Sidike Paheding, Evan Lucas, Timothy C. Havens, Peter C. Esselman

Michigan Tech Publications

Underwater image enhancement is often perceived as a disadvantageous process to object detection. We propose a novel analysis of the interactions between enhancement and detection, elaborating on the potential of enhancement to improve detection. In particular, we evaluate object detection performance for each individual image rather than across the entire set to allow a direct performance comparison of each image before and after enhancement. This approach enables the generation of unique queries to identify the outperforming and underperforming enhanced images compared to the original images. To accomplish this, we first produce enhanced image sets of the original images using recent …

A Transferable Approach For Quantifying Benthic Fish Sizes And Densities In Annotated Underwater Images, Peter C. Esselman, Shadi Moradi, Joseph K. Geisz, Christopher Roussi

Michigan Tech Publications

Benthic fishes are a common target of scientific monitoring but are difficult to quantify because of their close association to bottom habitats that are hard to access. Advances in image-acquisition technologies, machine vision and deep learning have made capturing and quantifying fishes with cameras increasingly feasible. We present a method and open-source software called ‘FishScale’ to estimate benthic fish lengths, numeric abundance and biomass density in underwater environments assessed with down-looking monocular images. ‘FishScale’ estimates fish abundances and size frequencies from near-nadir monocular images where fish have already been semantically segmented. The software accounts for lens distortion, underwater magnification effects …
