Distinguishing Mustela From Neogale (Mustelidae) Through Both A Qualitative And Quantitative Analysis Of Skull And Tooth Morphology, Ronald W. Peery

Electronic Theses and Dissertations

Weasels and mink (Mustela and Neogale) can be difficult to distinguish osteologically due to similarities in morphology, thus suggesting the need for an accurate tool in distinguishing among taxa. This study utilized a combination of character state and stepwise discriminant function (DFA) analyses to examine potential distinguishing features of skull and tooth morphology. Measurements and ratios were collected from all 18 extant musteline species, as well as the extinct Neovison macrodon, Mustela rexroadensis, Mustela meltoni, Mustela gazini, and Mustela jacksoni. Unidentified musteline specimens from the Gray Fossil Site were also included. Results of …

Experiences With Flood And Perceptions Of Flood Risk Among Members Of The Filipino American Community In Virginia Beach, Virginia, Anjelica Pascual Petsch

Institute for the Humanities Theses

The Filipino Americans living in Hampton Roads, Virginia have comprised of almost 2% of the region’s overall population, and 5.3% of the population in Virginia Beach, Virginia (United States Census Bureau, 2019) (Greater Hampton Roads Connects, 2021). Filipino Americans in Hampton Roads, like the rest of the population, are equally vulnerable to experiencing flooding when commuting to and from work or simply traveling around town, but previous research and surveys from the Hampton Roads Region have failed in their ability to capture this cultural diversity within perception of flood risk. In this paper, a qualitative research design was used to …

Executive Functions And Student Success During Physical Therapist Education: An Exploratory Study, Jane Roitsch, Martha L. Walker, Anastasia M. Raymer

Communication Disorders & Special Education Faculty Publications

BACKGROUND: Clinical reasoning relies on executive functions (EFs) that manage attention, inhibition, organization, and decision-making. Assessment of EFs may help identify students who excel at clinical reasoning, yet data showing this relationship in physical therapy (PT) education programs are lacking. The primary purpose of this exploratory study was to examine EFs in relationship to success in PT educational programs. METHODS: Thirteen third-year PT graduate students completed two EF tests which were compared to culminating scores in the program and admissions scores. RESULTS: A relationship existed between National Physical Therapy Examination (NPTE) and comprehensive exam results and one EF test score; …

The Role Of Emotional Attention Regulation In High Psychopathy Incarcerated Males, Michael K. Webb

Dissertations and Theses

This study examined the role of emotional attention regulation in men (N = 60) currently incarcerated in a Midwestern prison. Modern conceptualizations define psychopathy as a multifaceted and dimensional construct that includes atypical experience of affect, interpersonal problems, and remarkable social deviance. Attentional differences and deficient emotional experience have been shown to predict psychopathy and other outcomes related to the construct. However, attentional and emotional functioning in individuals high in psychopathy is complex and results have been shown to vary across discrete emotion states and experimental paradigms. The negative preception hypothesis (Kosson et al. 2018) suggests that these differences may …

Impacts Of Environmental And Anthropogenic Stressors On Amphibian Welfare, Diversity, And Distribution In The Upper Missouri River Basin, Kaitlyn Campbell

Dissertations and Theses

Climate change and anthropogenic stressors have contributed to rapid declines among various taxonomic groups; however, amphibian declines have been particularly intense and primarily stemmed from warming temperatures, habitat loss, exposure to contaminants, disease, and their subsequent interactions. Several climate mitigation strategies, like Bioenergy with Carbon Capture and Storage, have been proposed to alleviate the impact of rising temperatures; however, these proposals often fail to recognize and quantify the true impact on fauna, including changes in species distributions. To address this critical gap in knowledge, this research identified current amphibian distributions in the Upper Missouri River Basin and projected distribution changes …

Desde El Futuro: El Archivo Lemebel, Fernando A. Blanco

Faculty Journal Articles

The reflection on Pedro Lemebel’s work and public persona has been rigorous and exhaustive. Critics have analyzed his narrative, his work on radio, performances, political and media activism (Blanco 2004, 2017, 2020, Blanco y Poblete 2010, Poblete 2018, Bianchi 2018, Martínez 2021). However, not much have been written about the documentaries Pedro Lemebel. Corazón en Fuga (Quense, 2008) and Lemebel (Reposi, 2019). The goal of this article is to reflect on both films as testimonial exercises to preserve the artist-self. The paper explores this notion of self-archiving: that of documenting the future with a clear awareness of mortality and oeuvre.

Coevolutionary Methods Enable Robust Design Of Modular Repressors By Reestablishing Intra-Protein Interactions, Xian-Li Jiang, Rey P. Dimas, Clement T.Y. Chan, Faruck Morcos

Biology Faculty Publications and Presentations

enetic sensors with unique combinations of DNA recognition and allosteric response can be created by hybridizing DNA-binding modules (DBMs) and ligand-binding modules (LBMs) from distinct transcriptional repressors. This module swapping approach is limited by incompatibility between DBMs and LBMs from different proteins, due to the loss of critical module-module interactions after hybridization. We determine a design strategy for restoring key interactions between DBMs and LBMs by using a computational model informed by coevolutionary traits in the LacI family. This model predicts the influence of proposed mutations on protein structure and function, quantifying the feasibility of each mutation for rescuing hybrid …

Statistical Mediation Analysis In Regression Discontinuity Design For Causal Inference, Donna Chen

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Regression discontinuity designs (RDDs) are the most robust quasi-experimental design, but current statistical models are limited to estimates for the simple causal relationship between only two variables: the independent and dependent variables. In practice, intervening variables (or mediators) are often observed as part of the causal chain. Mediators explain the why and how a treatment or intervention works. Therefore, mediation and RDD analysis combined can be a useful tool in identifying key components or processes that make intervention programs effective while making causal inferences for improving student achievement, despite natural constraints, limitations, and ethical considerations. Without an integrated framework of …

As of 2020, accent modification instruction was added to a speech-language pathologist's Scope of Practice. This elective service is for individuals who wish to change or modify their speech patterns to increase speech clarity. In developing assessment and instructional programs geared towards accent modification instruction, considerations must be made for the listener and the speaker. A range of accent modification assessment materials and instruction programs currently exist. The purpose of this study was to determine if a simplified Likert-type rating scale, ranging from "not comprehensible" to "comprehensibility unaffected," could serve as a quick tool to measure a non-native English speaker's …

Characterization Of The Multifunctional Enzyme Proline Utilization A, Yizi Mao

Department of Biochemistry: Dissertations, Theses, and Student Research

Proline is a unique and important amino acid. Proline is a proteogenic amino acid and its metabolism is involved in many critical cellular functions. Therefore, proline metabolism is tightly regulated, and dysfunction of proline metabolism is related to human diseases. The first step of proline oxidization to ∆¹-pyrroline-5-carboxylic acid (P5C) is catalyzed by proline dehydrogenase (PRODH). P5C is then non-enzymatically hydrolyzed to glutamate-γ-semialdehyde (GSA), which can be further oxidized to glutamate by P5C dehydrogenase (P5CDH/GSALDH). In Gram-negative bacteria, the PRODH and P5CDH enzymes are expressed as one polypeptide called proline utilization A (PutA). In some Gram-negative bacteria an …

The Impact Of Beneficial Organisms In Corn Agroecosystems, Callie Rosalind Braley

Doctor of Plant Health Program: Dissertations and Student Research

Corn is one of the world’s, and Nebraska’s, most important crops. Millions of acres are planted to corn each year in the Cornhusker State. However, each year there are a plethora of arthropod, weed, and microorganism pests that rob farmers of reaching their maximum yield potential. There are many options available to manage these pests in corn agroecosystems, but one option is often underutilized: beneficial organisms. For each pest, there are a variety of natural enemies that can assist in mitigating the damage caused by pests.

Many beneficial organisms exist, and they can be grouped by the type of pest …

Intricacies In Agronomic Management: The Role Of Interdisciplinary Education, Adam M. Striegel

Doctor of Plant Health Program: Dissertations and Student Research

As a science, agronomy is built upon the connection of inter-disciplinary fields of study. Management (M) of various discipline considerations (and their subsequent interactions) can be influenced by and have significant effects on genetic by environment (GxE) expression. This has led to the promotion of GxExM systems. However, optimizing GxExM programs requires extensive, interdisciplinary knowledge. To evaluate interdisciplinary training provided in undergraduate education, 11 four-year universities were selected in the United States that offer baccalaureate degree majors in agronomy or crop science. Surveys of undergraduate programs of study were conducted, with all required coursework separated into general degree components (general …

Examination Of Cajeput Oil (Melaleuca Cajuputi) Phytochemicals As Tools To Manage The Yellow Fever Mosquito (Aedes Aegypti L.), Ellis Johnson

Department of Entomology: Dissertations, Theses, and Student Research

The yellow fever mosquito, Aedes aegypti L., is among the most important insects as it pertains to public health. It vectors several health-endangering pathogens, including yellow fever, dengue fever, chikungunya, and Zika viruses. Insecticides are among the most effective tools used to manage mosquito populations however, their efficacy to manage mosquito populations is being threatened by insecticide resistance. This ongoing threat warrants new chemical strategies to reduce or incapacitate a mosquito population capable of pathogen transmission. Plant essential oils are candidates for identifying novel management tools for disease-vectoring arthropods. Commercially, essential oils have been used for pharmaceuticals, flavoring, fragrances, cosmetics, …

Comparing Machine Learning Techniques With State-Of-The-Art Parametric Prediction Models For Predicting Soybean Traits, Susweta Ray

Department of Statistics: Dissertations, Theses, and Student Research

Soybean is a significant source of protein and oil, and also widely used as animal feed. Thus, developing lines that are superior in terms of yield, protein and oil content is important to feed the ever-growing population. As opposed to the high-cost phenotyping, genotyping is both cost and time efficient for breeders while evaluating new lines in different environments (location-year combinations) can be costly. Several Genomic prediction (GP) methods have been developed to use the marker and environment data effectively to predict the yield or other relevant phenotypic traits of crops. Our study compares a conventional GP method (GBLUP), a …

The UDL framework is an instructional design framework designed to enhance access, engagement, and learning using three overarching principles: multiple means of engagement, multiple means of representation, and multiple means of action and expression. The researcher utilized a two-group randomized control trial (RCT) with pre- and posttest measures. The control group completed a publicly available module on functional behavior assessment while the intervention group completed an enhanced version of the same module. Results demonstrate that both the intervention and …

An Analysis Of Performance-Based Funding Policies At An Open Access Institution, John Brady

Electronic Theses and Dissertations, 2020-2023

Performance-based funding policies have become popular among state legislators seeking ways to hold public higher education institutions accountable. Approximately 30 states currently use performance-based funding policies to tie state appropriations to institutional outcomes according to a defined set of metrics. Despite the popularity of the policy approach, very little empirical evidence exists to suggest that performance-based funding is effective in producing the often-intended outcomes of increased student retention and degree attainment rates. Numerous studies have indicated that these policies may produce unintended outcomes including the restriction of access, the gaming of performance-based funding systems, and the widening of equity gaps. …

Boilerplate Collusion: Clause Aggregation, Antitrust Law, & Contract Governance, Orly Lobel

Minnesota Law Review Vols. 106:2 onward (2021-present)

Contract clauses should be assessed in relation to each other when examining their meaning, validity, and enforcement. In contemporary markets, drafters create impenetrable bundles of clauses and sets of interrelated contracts operating together. This Article exposes the ways that a contract is larger than the sum of its separate clauses and a set of interrelated contracts is more harmful than the aggregation of each contract on its own. The Article further shows that contract adjudication embeds these insights intuitively, but both contract law and antitrust law have yet to develop a principled and consistent analysis of how contract clauses collude …
