Blues Is My Business (And Business Is Good?), David N. Larson

Electronic Theses and Dissertations

This work focuses on the social, political, and economic trends that govern the blues music scene in Clarksdale, Mississippi. Clarksdale is seen as a sort of “ground zero” in the blues world, it is often referred to as, “the land where blues began.” This claim is not without merit but it is not strictly historically accurate. Many of the town’s spokespeople use euphemisms that distort the troubled history of race relations in the town and its music spaces.

This investigation centers around the economic state of the town’s tourism industry, the individuals who act as the town’s promoters, and the …

Face Detection Using Web Images, Chris Zhao

Electronic Theses and Dissertations

The current facial recognition algorithms struggle with accuracy on real world cases. Haar cascade based algorithms are fast, but require fine tuning per image in order to achieve the best results. When tasked with images where there are multiple faces at different locations, the current algorithms seem to underreport the number of faces. This study attempts to produce a more accurate classifier through the use of taking the maximum result of multiple Haar cascade classifiers with differing parameters. To do this, a web image scraper was written to gather real world images from Google images and Flickr. These images were …

A Call For Critically Inclined Higher Education Data, Wendy A. Fish

Electronic Theses and Dissertations

The economic logic of neoliberalism has reached its zenith—now firmly entrenched in our political, social, and cultural transactions (Giroux, 2014; Harvey, 2005). As a result, we stand on the precipice of a new era—the data era—in which neoliberalism’s orientation towards accountability, micro-management, and hierarchical ordering mediates all social and political narratives. Data, it is said, is fast becoming “the new oil”—the most valuable global resource (Bhageshpur, 2019; Harari, 2018).

This is problematic. Although there are countless ways in which the application of data has improved the world, it has a long, dark history as a technology of oppression. Yet, data …

Plant-based diets contain numerous flavonoid compounds that produce antibacterial effects and gut health improvement. Genistein is among the most abundant isoflavones present in a plant-based diet and can be found in high amounts in soy products (up to 1g Kg-1). We describe here a robust method to identify genistein tolerant and metabolizing bacteria in swine gut microbiota and to screen the strains that have antibacterial and immunestimulatory properties. Such strains could be developed as non-antibiotic alternatives to prevent enteric infections in pigs and improve gut immunity. To this end, a mini bioreactorbased system was used to enrich genistein metabolizing bacteria …

Post-Fledging Habitat Selection And Movements Of Juvenile Mallards In The Prairie Pothole Region, Cynthia E. Anchor

Electronic Theses and Dissertations

The Prairie Pothole Region (PPR) of North America provides critical habitat for waterfowl across life stages, but anthropogenic changes to the landscape have negatively impacted habitat quality for waterfowl. The mallard (Anas platyrhynchos) is abundant and socioeconomically valuable in the PPR, as it is a preferred target species of waterfowl hunters. Extensive research has evaluated breeding ecology of mallards in the PPR, but the period between juvenile mallards fledging and migrating has rarely been studied. The post-fledging ecology of juvenile mallards is a vital consideration for comprehensive waterfowl management. Further, juvenile mallards are a significant portion of hunter harvest at …

Philosophical Anthropology And Biblical Interpretation In John Paul Ii’S Theology Of The Body, Shawn Conoboy

Electronic Theses and Dissertations

In the Theology of the Body, through a series of Wednesday Catecheses, John Paul II presents a magisterial understanding of the sacrament of marriage and of marriage and family ethics. At the same time, John Paul II presents a theological anthropology, which forms a basis for the magisterial teaching. His theological anthropology is developed through an exegesis of selected biblical texts, especially Genesis 1-3 and Ephesians 5, and through an application of a philosophical anthropology articulated by Karol Wojtyła. This dissertation draws the connection between the philosophical anthropology of Wojtyła, especially as it is articulated in his major works, …

The Lived Experiences Of Self-Concealment Among Lgbq+ Counselors In The Workplace, Richard Charette Ii

Electronic Theses and Dissertations

This study sought to unearth the narratives of LGBQ+ counselors’ experiences of self-concealment in the workplace. Self-concealment was an identity management strategy that was defined as an active, and sometimes persistent effort to conceal LGBQ+ identity. Self-concealment of affectional identity was well researched in workplace contexts, however only one study existing study examined self-concealment among LGBQ+ counselors. In that previous qualitative inquiry, Jeffery and Tweed (2014) called for further exploration of self-concealment among LGBQ+ counselors when self-concealment emerged as a surprising finding.

The phenomenon of self-concealment was under-researched in counseling but has been extensively conceptualized as both a developmental stage …

Detecting Viral Particles In Vitro Using Photoacoustic Flow Cytometry, Anie-Pier Samson

Electronic Theses and Dissertations

The Covid-19 pandemic is a powerful example of just how damaging the rapid spread of an unknown virus can be. Viruses have the ability to spread rapidly amongst individuals if not treated and controlled. The first key step towards treatment is the timely and specific diagnosis of the virus causing the infection. An innovative method for the rapid detection of viral particles in solution consists of tagging the viral particles paired with using photoacoustic flow cytometry to irradiate the particles and get a signal. The high affinity of Streptavidin for Biotin can be used to bind Streptavidin-coated microspheres to biotinylated …

Analysis Of Spore Shape Determination In Streptomyces, Ning Sun

Electronic Theses and Dissertations

Streptomycetes are Gram-positive, soil-dwelling bacteria that possess a complex life cycle with the alternation of vegetative mycelium, aerial mycelium, and spores. Streptomyces. coelicolor spore maturation is a complex process that involves spore shape metamorphosis from cylindrical pre-spores into ellipsoid spores, but the details of this process have remained enigmatic. Previously, our lab identified a novel gene ssdA that might play a role in spore shape determination using a transposon-based insertion mutagenesis in S. coelicolor. In this study, I isolated a S. coelicolor ssdA-null mutant that showed increased colony hydrophobicity and misshapen spores in sizes and shapes, confirming the …
