The History, Development, And Continual Evolution Of The Percussion Theatre Genre, Steven L. Wimberley

LSU Doctoral Dissertations

During the twentieth century, artists in every discipline sought to create new, original art that would both challenge societal norms and expand their respective art to new extremes. This expansion in contemporary music saw the emergence of electronics, chance elements, “found sounds,” speaking, acting, and physical gestures. As we continue through the twentieth century, we also see the onset of the percussionist as an independent musical artist and a desire for original music for percussion. The intersection of these new developments created what is known as percussion theatre.

Percussion theatre can be broadly defined as a genre of musical composition …

Extremal Connectivity In Graphs And Matroids, Yiwei Ge

LSU Doctoral Dissertations

Connectivity is a central theme in both graph theory and matroid theory. This dissertation investigates extremal connectivity in graphs and matroids, with emphasis on unavoidable structures and minimal connectivity phenomena.

Chapter 2 introduces cycle-contraction minors of graphs and investigates their structural properties. We establish a connection between cc-minors and induced subgraphs via graph duality. The main result gives an unavoidable-families characterization for cc-minors of sufficiently large loopless $2$-connected graphs.

Chapter 3 studies super-minimally $3$-connected graphs, namely $3$-connected graphs that have no proper $3$-connected subgraphs. We establish extremal bounds on structural parameters of these graphs, including the minimum number of degree-$3$ …

Organizing To Engage: A Framework For Conflict Strategy, Paul Mason Carpenter

Dissertations

Conflict strategy can be exceedingly complex. While many of the basics are simple, even the simple can be highly complicated to execute. The Schlieffen Plan in World War I appeared straight forward, but execution was a great deal more complex. It failed and the result was years of trench warfare.  In addition, leaders entering conflict may not fully appreciate the full context, its effect, and the need for a long term result--a better state of peace.

Strategy and tactics may be challenging to transform as an engagement evolves. In addition, strategists must often commit to courses of action within very …

Female Indentured Servants And The Law In The Colonial Chesapeake, Jennifer Daniel Corbitt

Electronic Theses and Dissertations Archive

Abstract In colonial Virginia and Maryland, indentured servants were the primary engine of the colony's economy. In theory, the temporary exchange of labor for passage and potential social mobility offered women and men a similar opportunity to rise above their original station. However, the historical research of the past few decades has revealed that women had a distinctly different experience with the law than men. This thesis will argue that colonial law defined a particular and punitive form of servitude for white indentured women, viewing them as reproductive liabilities rather than as purely in economic assets. While The author has …

The Materiality Of Religious Syncretism And Co-Production In The Catacombs Of Sicily And Malta: Novel Techniques For The Interpretation And Dissemination Of Legacy Data, Madeleine A. Kraft

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the lengthy history of the investigations into the catacombs of Sicily and Malta. These investigations, in some cases, began as early as the 17th century. They have maintained the intrigue of archaeologists beginning in the late 19th century. In doing so, these spaces have amassed truly remarkable amounts of data and of interpretations of that data. This legacy data has proved simultaneously a barrier and an entrance to understanding these complexes.

The Effect Of Visual And Narrative Perspective On Memory For Social Interactions, Allen Hagen

Electronic Theses and Dissertations 2020 - Present

The visual perspective we experience events from is particularly important in social settings that are both referenced over time and within areas of importance such as courtroom settings, police interrogations, and workplace evaluations. The current study investigated the effect of visual encoding perspectives (first-person, observer) during valenced social interaction footage on the recognition of old or altered footage (changed perspective, valence, or all new), as well as emotional metamemory judgements for the event. The study also investigated the effect of written narrative perspective of event descriptions (first-person, second-person) on these dependent variables. The experiment revealed a significant effect of encoding …

Navigating Help In Stem: How Seeking And Receiving Help Shapes Women’S Self Perceptions And Memory, Samantha A. Mckinney

Electronic Theses and Dissertations 2020 - Present

Prior research suggests that help-seeking is a social process shaped by interpersonal context, yet less is known about how help type and partner characteristics influence self-related outcomes in STEM settings.

Across two studies, participants completed a STEM task and interacted with a simulated partner who provided help.

In Study 1 (N = 215), participants received the type of help they requested, allowing for an examination of how help type and …

Development And Application Of A Multiplex Bead-Based Platform For Quantifying Host-Pathogen Protein-Protein Interactions, Larah Gorayeb

Electronic Theses and Dissertations 2020 - Present

Host-pathogen protein-protein interactions are the key drivers of infectious diseases, where events such as pathogen adhesion and signaling are directly associated with disease severity. One example of this is Malaria, in which the Plasmodium falciparum infected erythrocytes adhere to endothelial receptors to avoid splenic clearance. This study investigated interactions between PfEMP1 CIDR1 field domains and host receptor CD36 using a multiplex platform to quantitatively determine binding affinities. Variants RP18 and RP27 exhibited strong affinity, suggesting a role in cytoadherence and disease severity. To evaluate broader applicability, the platform was expanded to the interaction between host protein SIVA1 and Helicobacter pylori …

The Role Of Intravascular Ultrasound Imaging In 30-Day Readmissions Among Acute St-Elevation Myocardial Infarction Patients, Britta Watson

MUSC Theses and Dissertations

Cardiovascular disease (CVD) remains one of the leading causes of death in the United States. Coronary artery disease (CAD) is the largest contributor to deaths that result from cardiovascular disease. When CAD is left untreated, it can result in an acute ST elevation myocardial infarction (STEMI). To treat coronary blockages caused by CAD, a percutaneous coronary intervention (PCI) is performed. A PCI is a non-invasive procedure that uses coronary balloons and stents to open a narrowed or blocked coronary artery and restore blood flow.

An acute ST elevation myocardial infarction (STEMI) is a major cause of early hospital readmissions. Technological …

Does Volume Cycling Elicit A Skeletal Muscle Hypertrophy Re-Sensitization Effect? A Comparison Of Constant Versus Cycled Resistance Training Protocols, Joshua C. Pelland

Electronic Theses and Dissertations 2020 - Present

Purpose: This study examined whether volume cycling in resistance training can elicit a skeletal muscle hypertrophy re-sensitization effect without muscle atrophy. We hypothesized that muscle size would be maintained during lower volume phases, that re-sensitization would occur following these phases, and that overall hypertrophy would be similar between cycled and constant volume conditions.

Methods: Thirty-seven trained men and women had their lower limbs randomized to either a constant volume (12 sets/week throughout) or cycled volume (alternating 4-week phases of 12 and 4 sets/week) condition for unilateral calf press training over 20 weeks. Lateral and medial gastrocnemius muscle thickness (MT), calf …

Democracy At Work And The Promise Of Dignity: Worker Cooperatives And The Experiences Of Workers Of Color, Isabella "Leila" Thomas

Undergraduate Theses

The United States faces profound wealth inequality which has also disproportionately disadvantaged people of color in terms of economic security. This study investigates how participation in worker cooperatives, which provide higher wages and greater worker benefits on average, impacts worker-members of color. The study draws on qualitative interviews with worker members from largely minority-led cooperatives. It explores how the key cooperative principles of democratic decision-making, autonomy, and community engagement can counteract marginalization. This paper fills significant gaps in research on workplace dynamics by applying Blustein & Allan (2025)'s recently formulated dignity-at-work framework to an alternative, democratized workplace model rather than …

Rethinking Sustainable Development: Postcolonial Perspectives And Alternative Pathways To Progress, Lauren M. Pappalardo

Undergraduate Theses

Sustainable development, promoted as a universal model, does not reflect a neutral global goal as advertised, but rather, often reproduces longstanding colonial power relations through political projects, and should be reimagined to endorse a multifaceted approach through consideration of alternative worldviews and values, emphasizing context dependent processes and aspirations. Thus, what might context dependent constructions of sustainable development look like in implementation? How do various cosmologies which inspire Indigenous and economic driven worldviews fit into theories of global politics? This thesis offers an understanding of current global development issues and successes and offers suggestions for a more equitable approach to …
