Department of Radiology Faculty Papers

Multiparametric MRI (mpMRI) is currently the standard imaging modality for the diagnosis of prostate cancer; however, studies have reported that targeted biopsy based on mpMRI may miss approximately 30% of clinically significant cases. Recent advances in ultrasound imaging have improved its accuracy for detection of prostate cancer. Newer techniques such as MicroUS, elastography, contrast-enhanced ultrasound (CEUS), and contrast ultrasound dispersion imaging (CUDI) have enabled a comprehensive, real-time, and relatively inexpensive approach to evaluate the prostate gland. Multiparametric ultrasound (mpUS) integrates multiple parameters from these techniques to generate multiparametric maps akin to those produced by mpMRI, to localize prostate cancer. This …

Vascular Calcification In A Mouse Model Of Chronic Kidney Disease And In Human Peripheral Arterial Disease, Breanna Pederson

Theses and Dissertations

Vascular calcification is a process in which calcium and phosphate crystallize to form hydroxyapatite in the extracellular matrix of blood vessels. There are two forms of arterial calcification: intimal and medial, which occur via different etiologies. Intimal calcification is associated with atherosclerosis and occurs in the layer of endothelial cells adjacent to the artery lumen. Medial arterial calcification (MAC) is independent of atherosclerosis and occurs in the middle, muscular layer of the artery. MAC is strongly associated with aging, diabetes mellitus, and chronic kidney disease (CKD). MAC is frequently in patients with peripheral arterial disease (PAD). Most studies to date …

If We Only Had A Wheelbarrow: Asset-Based Pedagogy In The Elementary Classroom, Elizabeth Bedell Oct 2024

If We Only Had A Wheelbarrow: Asset-Based Pedagogy In The Elementary Classroom, Elizabeth Bedell

Theses and Dissertations

The challenges facing today’s educators are much and many. Among them ranks the persistent underachievement of students from racially and culturally diverse backgrounds. Attempts to remedy this have historically taken a deficit approach, one that attempts to “fix” students by melding them to the norms of the dominant culture, ultimately diminishing their cultural ways of knowing and being and perpetuating inequity. Although educators want to do better, most have simply not been provided with the professional learning that would support their centering students’ voices and experiences as essential to learning

With a focus on asset-based pedagogy, this convergent mixed methods …

Winning And Losing At The Federal District Courts, Madison Shanks Oct 2024

Winning And Losing At The Federal District Courts, Madison Shanks

Theses and Dissertations

The federal criminal courts are unique compared to the rest of the justice system. Cases in these courts pit a government backed prosecutor with an informational and first-moving advantage, against an often-disadvantaged defendant in an adversarial system that ultimately determines who wins and who loses. This asymmetry in criminal cases at the federal district courts presents a situation in which we can understand how courtroom actors matter for the justice process, and specifically if and how attorneys’ strategies differ and ultimately influence outcomes for their clients. This dissertation project builds on an existing data collection project that captures motion filings …

The Institutional Impact Of Left-Leaning Populism In Latin America, Nicolas Cachanosky, Joao Pedro Bastos, Alexandre Padilla, Karla C. Hernandez Oct 2024

The Institutional Impact Of Left-Leaning Populism In Latin America, Nicolas Cachanosky, Joao Pedro Bastos, Alexandre Padilla, Karla C. Hernandez

Hunt Institute Working Paper Series

We study the institutional impact of 21st-century left-leaning populist regimes in Latin America. Looking at the representative left-leaning populist regimes in Argentina, Bo-livia, Ecuador, Nicaragua, and Venezuela, we find that these types of populist regimes impose a significant undermining on the liberal-democracy institutional quality of their countries. The institutional cost is both significant and long-lasting, and our synthetic counterfactual suggests that liberal democratic institutions would have im-proved if not for these populist regimes.
