Immune Modulation As A Therapeutic Target In An Α-Synuclein Model Of Parkinson’S Disease, Meena Subhashini Subbarayan

USF Tampa Graduate Theses and Dissertations

Parkinson’s disease (PD) is the second most common neurodegenerative disorder affecting about 1.5 million people in the United States with more than 60,000 people diagnosed each year. It is classically characterized by four major symptoms: tremor, postural instability, stiffness in joints, and slow movement (bradykinesia). Pathologically PD is characterized by up to 70% loss of dopaminergic neurons in substantia nigra pars compacta (SNpc) of midbrain and accumulation of presynaptic protein called α-synuclein (α-syn) within dopaminergic neurons that extend to the striatum. This disrupts the nigrostriatal pathway leading to the motor symptoms seen in PD patients. Microglia, the innate immune cells …

The West Knows Best: East Germans Left Behind After Unification, Arwen A. Puteri

USF Tampa Graduate Theses and Dissertations

The East-German euphoria of unification in 1989 and the subsequent transition from a communist to a market economy that had promised West German standards and prosperity in East Germany vanished rapidly. A hastily negotiated unification treaty and emerging West German dominance – in numbers and economic power – resulted in vast unemployment, bankruptcies, and the large-scale collapse of the East German economy. In addition, East-German culture, accomplishments, and experiences were not respected and valued in a unified country that was focused on Western values, languages, and ways of life. With nothing to offer, East Germans became hopeless and resentful and …

Humanistic Climate Philosophy: Erich Fromm Revisited, Nicholas Dovellos

USF Tampa Graduate Theses and Dissertations

Given the current juncture in history, humanity is faced with the herculean task of adapting to a tumultuous present and a gimmer future. Should climate projections be accurate, there is little time to waste. This work makes the claim that we are not only in a political gridlock but also in an academic one. Researching climate philosophy from its inception, the concluding view is that no major progress, outside of a standardized descriptive analysis, has been achieved. Thus, the work evaluates an array of climate philosophers e.g. Stephen Gardiner, James Garvey, Peter Singer, Walter Sinnott-Armstrong, etc., with specific emphasis on …

Bodily Harm: An Analysis Of The Phenomenological And Linguistic Aspects Of Harm And Trauma, Grant Samuel Peeler

USF Tampa Graduate Theses and Dissertations

This work seeks to explore the phenomenological experience of harm through an investigation of trauma and its existential features. Harm, despite its importance for many topics in both Political Science and Political Theory, is not often investigated as a subject in itself. By interrogating elements of Merleau-Ponty’s uniquely embodied philosophy, this work seeks to further our understanding of harm as a phenomenon which is both uniquely subjective and yet socially informed.

The text is split into two halves – with the first offering an exegesis of relevant sections of Merleau-Ponty’s Phenomenology of Perception, and the second engaging with contemporary secondary …

USF Tampa Graduate Theses and Dissertations

Language is a very complex matter in Haiti. One of the most pressing issues related to language in Haiti is the aspect of violence. The violence that exists through linguistic means in Haiti today has for its basis the same mechanism that existed during the colonial era in Haiti. The same western concept of colonial social dualities, and unequal distribution of esteemed associates to African and European cultures are still at the forefront of linguistic violence. The only difference being that those ideas of colonial superiority, which informed those recurring acts of violence, are now self-imposed.

In Haiti, the nature …

Warfare In Christianity And Islam: Unveiling Secular Justifications And Motivations Behind So-Called Religious Violence, Onur Korkmaz

USF Tampa Graduate Theses and Dissertations

The phenomenology of religion has received the most attention in social science because it has shaped society on social, political, and economic levels throughout history. Religion can be an organization that brings people together and develops a sense of identification, while also acting as a divisive structure for those of other faiths or nonbelievers. And so, we have witnessed the rise of both religious tendencies and violent acts for the last two decades, occasionally intertwined. Various belief systems have increasingly become a factor that politicians, intellectuals, and the mainstream media associate with violence-based modern warfare. However, scholars and analysts who …

Feature Selection Via Random Subsets Of Uncorrelated Features, Long Kim Dang

USF Tampa Graduate Theses and Dissertations

The role of feature selection is crucial in many applications. A few of these include computational biology, image classification and risk management. In biology, gene expression micro array data sets have been used extensively in many areas of research. These data sets typically suffer from an important problem: the ratio between the number of features over the number of examples is very high. This problem mainly affects prediction accuracy because it is best to collect more labeled examples than features. A correlation based random subspace ensemble feature selector (CCC_RSM) was proposed to handle this problem [5]. In this approach, first …

Contemporary educational legislation in the last 30 years has reflected the age of accountability in which positive student academic outcomes and yearly student progress are the main goals of the school system. In addition to accountability legislation, schools are mandated to implement multi-tiered systems of support (MTSS) to provide a continuum of services for all students. To implement MTSS and the necessary system changes, many schools are using distributed leadership models and practices such as leadership teams to maximize the human and material resources available. This study examined the conceptualization and enactment of distributed leadership in a school that is …

Establishing Topological Data Analysis: A Comparison Of Visualization Techniques, Tanmay J. Kotha

USF Tampa Graduate Theses and Dissertations

When visualizing data, we would like to convey both the data and the uncertainty associated with it. There are many incentives to do this, ranging from hurricane path projection to geographical surveys. Important decision making tasks rely upon humans perceiving a clear picture of the data and having confidence in their decisions. Topological Data Analysis has the potential to visualize the data as features or hierarchies in ways that are familiar to human intuition, and thus could help us convey the variation associated with uncertainty.

In this thesis, we evaluate four visualization techniques: color maps, isocontours, Reeb graphs, and persistence …
