Navigating The Ethically Complex And Controversial World Of College Athletics: A Humanistic Leadership Approach To Student Athlete Well-Being, Johnette (Jay) Caulfield, Felissa K. Lee, Catharyn Baird

Management Faculty Research and Publications

The college athletics environment within the USA is ethically complex and often controversial. From an academic standpoint, athletes are often viewed as a privileged class receiving undue benefit. Yet closer inspection reveals that student athletes are at risk psychologically, physically, and intellectually in ways that undermine development and flourishing. This reality stands in troubling contrast to the prosocial, virtue-based goals expressed by university mission statements. Given the role of sport in many university business models, college athletics invites scrutiny from a business ethics standpoint. Using a humanistic leadership perspective (Pirson in: Humanistic management: protecting dignity and promoting well-being, Cambridge University …

Genome-Wide Identification Of Wrky Transcription Factor Encoding Genes In Amborella Trichopoda Baill. (Amborellaceae), Bijaya Pradhan

Electronic Theses and Dissertations

WRKY transcription factors (TFs) are DNA-binding proteins, which play important roles in managing plant stresses and regulating growth and development processes. The WRKY TF family has expanded significantly through genome/gene duplications in the plant evolutionary process. Although the WRKY TFs have been identified in hundreds of plant species, they are yet to be identified in Amborella trichopoda, a species that represents the most basal group of Angiosperms. The main objectives of this study were to conduct genome-wide identification of the WRKY gene family in A. trichopoda and to assess their homologs in Angiosperms. In this study, we identified …

Identifying Adp-Ribosylation As The Biochemical Signal That Marks Dna-Protein Crosslinks For Sprtn-Dependent Proteolysis, Katelyn Hurley Jan 2022

Identifying Adp-Ribosylation As The Biochemical Signal That Marks Dna-Protein Crosslinks For Sprtn-Dependent Proteolysis, Katelyn Hurley

Electronic Theses and Dissertations

DNA-protein crosslinks (DPCs) form when proteins covalently attach to DNA. It is estimated that hundreds of DPCs form in our cells each day. Because these lesions are cytotoxic, mammalian cells have evolved multiple intricate repair systems to remove DPCs and restore genome integrity. One mechanism mammalian cells rely on for DPC repair is direct proteolysis by the metalloprotease, SPRTN. While it is known that SPRTN degrades a heterogenous array of DPCs, including both naturally occurring and chemically induced, how SPRTN selects DPCs amongst chromatin-associated proteins remains unknown. Our main objective is to determine how DPC repair is regulated. In Chapter …

Assessment Of Aged Woodchip Bioreactor Physical And Hydraulic Properties, Shelby Duncan Jan 2022

Assessment Of Aged Woodchip Bioreactor Physical And Hydraulic Properties, Shelby Duncan

Electronic Theses and Dissertations

Denitrifying woodchip bioreactors are a critical tool for mitigating nitrate loading to downstream water bodies. The properties of the woodchip are a key factor in the design of the bioreactor which are usually designed to optimize that retention time of the water being treated. Retention time is affected by active flow volume, porosity, and flow rate. As a bioreactor ages, the carbon material will break down and, in some cases, sedimentation will occur within the bioreactor. Both processes will affect the porosity and hydraulic performance of the bioreactor. When flow through the bioreactor is significantly different than the original design, …

A Novel Crispr/Cas Gene Editing System For Plants Which Bypasses Genetic Transformation And Tissue Culture, Aastha Acharya Jan 2022

A Novel Crispr/Cas Gene Editing System For Plants Which Bypasses Genetic Transformation And Tissue Culture, Aastha Acharya

Electronic Theses and Dissertations

CRISPR/Cas system is a powerful gene-editing tool that has revolutionized gene editing in many ways. However, the current delivery methods for using CRISPR/Cas system inn plants have some drawbacks that have greatly limited their routine application in plant research and improvement. Specifically,, the methods heavily rely on either genetic transformation for delivering Cas and/or its gRNA coding sequences into the targeted cells or tissue culture, or both for recovering the whole edited plants. To overcome these drawbacks, we have developed a simple, easy to use yet effective system for CRISPR/Cas gene editing in plants that can bypass genetic transformation and …

The Racist Roots Of The War On Drugs & The Myth Of Equal Protection For People Of Color, Steven A. Ramirez, Andre Douglas Pond Cummings Jan 2022

The Racist Roots Of The War On Drugs & The Myth Of Equal Protection For People Of Color, Steven A. Ramirez, Andre Douglas Pond Cummings

Faculty Publications & Other Works

By 2021, the costs and pain arising from the propagation of the American racial hierarchy reached such heights that calls for anti-racism and criminal justice reform dramatically expanded. The brutal murder of George Floyd by the Minneapolis police vividly proved that the social construction of race in America directly conflicted with supposed American values of equal protection under law and notions of basic justice. The racially-driven War on Drugs (WOD) fuels much of the dissonance between American legal mythology—such as the non-discrimination principle and the impartial administration of the rule of law—and the reality of race in the United States. …
