In/Visible, Raymond Thompson Jr

Graduate Theses, Dissertations, and Problem Reports (ETD)

My MFA thesis and supporting exhibition focus on challenging the United States’ photographic archive that often left out African-American people. The work, through the use of appropriation and alternative photographic processes, disrupts America’s historical visual archive and notions that surround the white gaze. Through the unsettling of this visual space, new speculative narratives can be created to help imagine new futures. This work is the beginning of a process of mourning histories I have never known and reclaiming a place for myself and my family in the American landscape that is free of racial trauma.

Real Vs Fake Faces: Deepfakes And Face Morphing, Jacob L. Dameron

Graduate Theses, Dissertations, and Problem Reports (ETD)

The ability to determine the legitimacy of a person’s face in images and video can be important for many applications ranging from social media to border security. From a biometrics perspective, altering one’s appearance to look like a target identity is a direct method of attack against the security of facial recognition systems. Defending against such attacks requires the ability to recognize them as a separate identity from their target. Alternatively, a forensics perspective may view this as a forgery of digital media. Detecting such forgeries requires the ability to detect artifacts not commonly seen in genuine media. This work …

Pulsar Noise Processes And Emission Physics, Brent Jacob Shapiro-Albert

Graduate Theses, Dissertations, and Problem Reports (ETD)

Precision pulsar timing can be used to study many different astrophysically interesting phenomena, from the emission mechanism of pulsars to the detection of nanohertz gravitational waves. These analyses span topics such as studying the single pulses of pulsars and analyzing years of pulsar timing data from pulsar timing arrays (PTAs). Single-pulse studies allow us to glean information on the emission physics of pulsars on their shortest timescales, while PTA observations of millisecond pulsars (MSPs) allow us to not only study the pulsars themselves, but also probe the interstellar medium (ISM) and constrain the noise in the data for precision pulsar …

Tree Species Influence On Microbial Functional Gene Abundance And N Cycling In Riparian Soil, Elizabeth Matejczyk

Graduate Theses, Dissertations, and Problem Reports (ETD)

Little is known about how above-ground vegetation may differentially influence the below-ground microbial community structure, abundance, and function. Abundance of soil microbial N cycling genes responsible for nitrification (amoA), denitrification (nirK and nirS), and nitrous oxide reduction (nosZ) may vary with tree species and increasing N availability, and these variables may be used to predict production of NO₃^- and N₂O from soil. Variability of nitrification and denitrification rates have also been linked to tree mycorrhizal associations, with soil beneath tree species associated with arbuscular mycorrhizal (AM) exhibiting greater denitrification rates …

The current study investigates how the abundance of key functional N cycling genes within soil bacteria is altered by N deposition and further mediated by different dominant tree species at the Fernow Experimental Forest, WV. Soils were analyzed from two watersheds, where watershed 3 (WS 3) has been receiving experimental applications of N fertilizer that are 2x historic ambient N deposition and 5x the current ambient …

“Geeks And She-Eks”: The Relationship Between Younger Women’S Experiences In Popular Geek Culture And Their Interest In Stem Fields, Madeleine D. Butcher

Graduate Theses, Dissertations, and Problem Reports (ETD)

There is conflicting evidence about whether women’s participation in recreational, popular geek culture (e.g., gaming, fandom, science fiction consumption) can help close the gender gap in STEM fields. On one hand, these leisure activities can give women skills and experience that they can employ in STEM activities and culture. However, research also suggests that experiencing sexism while participating in geek culture activities can lower women’s motivation to participate in STEM. This thesis proposed that womens’ engagement in geek culture correlated with STEM efficacy and an interest in the STEM field. However, the type of experiences women have in geek culture …

Shutting The Door On Voting: The Effects Of "The Great Poll Closure", Joshua Matthew Squires

Graduate Theses, Dissertations, and Problem Reports (ETD)

The 2016 election was the first presidential election following the landmark Shelby County v. Holder (2013) case that invalidated Section 4(b) of the Voting Rights Act of 1965. The decision in Shelby meant that certain jurisdictions with histories of racial discrimination no longer needed permission or “preclearance” from the federal government before making changes to election administration procedures. Perhaps not coincidentally, voting jurisdictions across the United States also saw a record number of polling place closures - especially in formerly preclearance areas. Past research has studied the effects of precinct closures on voter turnout in individual counties and at the …

Effects Of 4-Methylcyclohexanemethanol On Stress Response Pathway Regulators, In Saccharomyces Cerevisiae, Suk Lan Ser

Graduate Theses, Dissertations, and Problem Reports (ETD)

Hydrotropes are small molecules capable of inducing liquid-liquid phase separation by altering the solubility and conformation states of organic compounds that are increasingly becoming important in organizing chemical reactions and regulating complexes. They prevent protein aggregation causing these proteins to form condensates. Mediator, a highly conserved multi-subunit complex, plays an important role in transcription. Med15, a subunit found within the tail domain of the Mediator complex, works with stress-induced transcription factors and is regulated by many kinases, including CDKs and the AMP kinase, Snf1. Living cells respond by changing molecular and cellular pathways when they are exposed to stressful conditions. …

Recovery Of Phosphorus From Florida Phosphatic Waste Clay, Amir Eskanlou

Graduate Theses, Dissertations, and Problem Reports (ETD)

This MS thesis examines the recovery of phosphorus (P) from Florida waste clay (WC). A comprehensive literature review revealed that: (i)-The most important values being lost to WC are P and rare earth elements (REEs). For the recovery of these values from WC, two crucial attempts are the removal of extremely fine-sized clays, followed by the recovery of phosphate content, which can pave the path for the recovery of REEs; (ii)-Any scientific/ technological solution should, at the same time, be economically and environmentally attractive to the industry. As such, moving from mostly chemical separation processes to the primarily physical/ physicochemical …
