Investigating Students’ Proficiency Across Statistical Software And Preferences Of Statistical Software Design, Sabrina White

Honors College Theses

This paper investigated students’ perceptions of their proficiency with statistical software applications and their preferences regarding software features. Results indicated that students’ statistical and coding experience, as well as the specific application used, did not significantly influence their self-perceived proficiency. This suggests that it may be more effective to focus on building student skills within a chosen application, rather than tailoring the application to match existing student capabilities. While students showed clear preferences for certain features, favoring clarity over depth, flexibility over safeguards, and built-in checks over unrestricted freedom, these preferences generally leaned toward balanced design rather than extremes. This …

Simulations Of Magnetar Spin-Down Lifetimes Using Magnetic Braking Models, Sophie Wessel

Honors College Theses

The beginnings of magnetar lifetimes are not very well understood. It is important to improve our understanding of magnetar origins in order to investigate possible evolutionary connections to other classes of NS, such as X-ray dim isolated NSs (XDINSs). Here we follow in the steps of another paper1 in modeling the spin evolution of magnetars, utilizing two avenues of evolution: one involving exponential B-field decay, and the other involving suband super-exponential B-field decay. We replicate the results of the paper, utilizing Monte Carlo methods to generate and evolve synthetic populations of magnetars, which are then compared to the current known …

Can Chaperones Promote Protein Splicing?, Hazel Thomas

Honors College Theses

Inteins are a mobile genetic element hypothesized to function as regulatory molecules in microbes. They bear a homing endonuclease domain for genome traversal, as well as specific residues allowing for protein splicing. In the protein splicing reaction, the intein is removed and the flanking residues, termed exteins, are ligated together with a peptide bond to form a functional host protein. Due to their interruption prior to splicing, inteins prevent a host protein from functioning until the intein ligates the two exteins. To measure factors that regulate protein splicing in vivo, an intein-based biosensor based on kanamycin resistance (K …

Designing A Control System With Automatic Transition Between Flight Modes For A Vtol Airplane, Asher Cunningham

Do Chaperones Promote Protein Splicing?, Christopher Powell, Christopher Lennon Dr

Scholars Week

Intervening proteins (inteins) are translated within host proteins and removed by protein splicing. Inteins are abundant in the microbial world and are often found within essential genes involved in DNA replications, recombination, and repair. Recent studies have made efforts to understand conditional proteins splicing, whereby intein removal and subsequent host protein activation is regulated by environmental factors. However, within the cellular context, factors influencing protein splicing are still largely unknown. In this work, we probe whether the chaperonin system GroEL/ES promotes protein splicing in vivo. Chaperonins, a family of chaperone proteins, help proteins fold under normal and stressed conditions. …

Microcanonical Analysis Of Semiflexible Homopolymers With Variable Bending Potential Width, Michael Gray

Scholars Week

I have developed an algorithm for finding phase transition in microcanonical data of simulations of homopolymers. These simulations model the behavior of homopolymers in an array of different conditions. This algorithm is generalized and can be applied to a variety of different systems. It works by taking repeated derivatives of the microcanonical entropy of the system and applying several filters, whose parameters are tuned algorithmically as well. Identification of phase transitions allows for the construction of a phase diagram.

“I Don’T Remember One Thing About Civic Education”: Elementary Preservice Teachers’ Perspectives On Civic Learning And Civic Engagement, Daniela Kruel Digiacomo, Laura H. Darolia, Carly Muetterties, Stephanie Mobley

Kentucky Teacher Education Journal: The Journal of the Teacher Education Division of the Kentucky Council for Exceptional Children

In this study, we examined elementary pre-service teachers’ perspectives on civic education and information and media literacy. We designed an intervention in an elementary social studies methods course to examine if pre-service teachers’ learning experiences shifted attitudes toward and imaginations about their future practice as teachers. Initial findings, based on interview transcripts and classroom artifacts, confirm the importance of bringing civic education and information and media literacy to young learners and offer insights into the kinds of support pre-service teachers may need to do so.

Stress As A Means Of Success: Investigating The Effect Of Stress Appraisals On Willpower, Ego Depletion, And Physiological Responses In College Students, Anna Minor

Honors College Theses

Stress impacts our emotions, cognition, behavior, and health. Although stress is abundant and unavoidable, recent research suggests our perception of stress can strongly influence its outcomes. The Biopsychosocial Model of Challenge and Threat (BPS) states that we appraise a stressful scenario in one of two ways: challenge or threat. A challenge appraisal involves a positive perception of stress and is associated with lower physiological output while a threat appraisal involves a negative perception of stress and increased physiological arousal. The current research seeks to apply the BPS to a cognitive task and consider its relation to willpower, ego depletion, and …

Spatial Analysis Of American Chestnut (Castanea Dentata) Distribution And Ecology In Kentucky’S Federal Lands, Jacob Raymond Pease

Murray State Theses and Dissertations

Anthropogenic factors have been the cause of the decline of tree species across the globe. From unsustainable logging and development to disease and improper management, threats to forests have taken their toll. The American chestnut (Castanea dentata) was once an integral basal tree species in Appalachian forests, but chestnut blight drove the species to functional extinction by the mid-1900s. The recent creation of genetically modified chestnuts gives hope for future restoration of the species throughout its historical range. Despite blight resistance, effective restoration will require optimal site selection for finding and planting chestnuts, which will maximize limited resources. …

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 …

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 …

Strong Neighborhood-Prime Labelings Under Ordinary & Gaussian Integers, Micheal Arnal-Brown

Murray State Theses and Dissertations

This thesis introduces and studies the notion of a strong neighborhood-prime labeling, a strengthening of the neighborhood-prime labeling where the label 1 can be assigned to any vertex in a graph. We prove that several graph families—including paths, cycles (excluding those congruent to 2 modulo 4), caterpillars, helm graphs, closed helm graphs, gear graphs, and graphs with universal vertices—admit such labelings, and also provide results to more general classes of graphs. We extend this new labeling concept to the Gaussian integers using a spiral order- ing on Z[i] and define a Gaussian analogue of strongly neighborhood-primeness. To support this extension, …
