General Relativistic Quasi-Local Angular Momentum Continuity And The Stability Of Strongly Elliptic Eigenvalue Problems, Shawn M. Wilder

Electronic Theses and Dissertations 2010 - 2019

In general relativity, angular momentum of the gravitational field in some volume bounded by an axially symmetric sphere is well-defined as a boundary integral. The definition relies on the symmetry generating vector field, a Killing field, of the boundary. When no such symmetry exists, one defines angular momentum using an approximate Killing field. Contained in the literature are various approximations that capture certain properties of metric preserving vector fields. We explore the continuity of an angular momentum definition that employs an approximate Killing field that is an eigenvector of a particular second-order differential operator. We find that the eigenvector varies …

Highwire Coordinates Synapse Formation And Maturation By Regulating Both A Map Kinase Cascade And The Ability Of The Axon To Respond To External Cues In The Giant Fiber System Of Drosophila Melanogaster, Melissa A. Borgen

Electronic Theses and Dissertations 2010 - 2019

The ubiquitin ligase Highwire is responsible for cell-autonomously promoting synapse formation in the Drosophila Giant Fiber system. highwire mutants show defects in synaptic function and extra branching at the axon terminal, corresponding to transient branching that occur in the course of giant synapse formation during metamorphosis. The MAP kinase pathway, including Wallenda and JNK/Basket, plus the transcription factor Jun, act to suppress synaptic function and axon pruning in a dosage sensitive manner, suggesting different molecular mechanisms downstream of the MAP kinase pathway govern function and pruning. A novel role for Highwire is revealed, regulating the giant fiber axon’s ability to …

In-Country: Identification Of Transformational Learning And Leadership In Human Rights Observers, Nancy D. Mcdonald

Electronic Theses and Dissertations 2010 - 2019

Haiti, the poorest country in the western hemisphere, has suffered through centuries of disenfranchisement, poverty, slavery, environmental disasters, internecine racial prejudice, and foreign infringement. Its people won independence from France in 1804 but only at the cost of huge human and financial losses. Since then, Haiti has known little freedom or democracy. In 1991, the first truly democratically elected president, Jean-Bertrand Aristide, was elected (with a 67% majority). Nine months later, he was deposed by a military coup d'état. During that time and the chaotic years that followed, groups of human rights observers traveled to Haiti in an attempt to …

Isocation And Characterization Of Conotoxins From The Venom Of Conus Planorbis And Conus Ferrugineus, Adriana Pak

Electronic Theses and Dissertations 2010 - 2019

The venom of marine gastropods belonging to the genus Conus has yielded numerous structurally and functionally diverse peptidic components. The increase variety of bioactive peptides identified in cone snail venoms is the product of the variety of molecular adaptations taken by Conus species in evolving neuroactive molecules to suit their diverse biological purposes. Toxins from cone snails are classified into two major groups. One group consists of disulfide-rich peptides commonly termed conotoxins; the second group comprises peptides with only one disulfide bond or none. In this work, we present the discovery and characterization from the marine snails C. planorbis and …

Knots In The Woods: An Assessment Of The Effects Of Location On Self-Directed Experiential Learning, Jasmine Coyle

Electronic Theses and Dissertations 2010 - 2019

My research measured completion and retention of procedural learning tasks, and declarative and procedural components of engagement in indoor and outdoor settings. Instructor-assisted Self-Directed Learning and Non-instructor-assisted Self-Directed Learning were implemented in the context of an Experiential Learning approach. Experimental covariates included student-specific variables such as background and experience, and environment-specific variables such as temperature, and humidity. AIC model averaging was used to identify the best-fitting mixed GLM models. Neither location, nor pedagogic method, proved to be a significant predictor of the probability that a student would complete the most complex of the procedural learning tasks, and the percent of …

Resegregation: The Impact On Education, Tameka L. King

Electronic Theses and Dissertations 2010 - 2019

This qualitative study examined the impact and implications of resegregation on students of color by capturing and analyzing the lived experiences of school principals leading high poverty and low poverty schools where resegregation was occurring. Despite the growing concern for resegregation, little has been down to reverse the adverse affects of this phenomenon. The body of research that has explored the essence of resegregation has in small volumes acknowledged the perception of school principals. A much clearer portrait of the impact resegregation was having on schools as perceived by school principals offered an in-depth understanding of the way in which …

Reframing Our Understanding Of Nonprofit Regulation Through The Use Of The Institutional Analysis And Development Framework, Denise R. Vienne

Electronic Theses and Dissertations 2010 - 2019

Regulation of the nonprofit sector is a subject of significant debate in the academic and professional literature. The debate raises questions about how to regulate the sector in a manner that addresses accountability while preserving the sector’s unique role in society. Central to the debate is the role of self-regulation. The nonprofit sector is recognized and defended as a distinct third sector in society. Cultural norms and values differentiate the purpose of the sector from the governmental and commercial realms. The legal regime secures rights, establishes organizational structures, and provides tax benefits that enable, reinforce, and protect participation in nonprofit …

Sequence Stratigraphy Of The Arcadia Formation, Southeast Florida: An Integrated Approach, Caroline Marie Wright

Electronic Theses and Dissertations 2010 - 2019

The Arcadia Formation is a mixed carbonate-siliciclastic rock unit that existed as a shallow carbonate ramp to platform environment during the Late Oligocene to Early Miocene Epoch. It can be divided into two distinct, informal sections based on lithological properties: the upper Arcadia Formation and lower Arcadia Formation. The sections are part of a major, third-order sequence that can be further divided into four higher-frequency, lower magnitude sequences: ARS1, ARS2, ARS3, and ARS4. The sequence boundary separating ARS2 and ARS3 represents a drastic change in the depositional regime from a high-energy, inner ramp/platform to a lower-energy, deep outer ramp environment. …

Seventeenth-Century Foodways Of British Puritans At Preacher’S Cave, Eleuthera, Bahamas: Zooarchaeological And Historical Evidence, Rose E. Gualtieri

ClassCrits is a network of scholars and activists interested in critical analysis of law, the economy, and inequality. We aim to better integrate the rich diversity of economic methods and theories into law by exploring and engaging a variety of heterodox economic theories; including reviving, from the margins and shadowy past, discussions of class relations and their possible relevance to the contemporary context.

As a participant in the ClassCrits VI conference entitled, “Stuck in Forward: Debt, Austerity and the Possibilities of the Political”, I sat there at the end of the first day and puzzled over the fact that our …

Americans All! The Role Of Advertising In Re-Imaging Ethnicity In America: The Case Of The War Advertising Council, 1939-1945, Jacqueline S. May

Electronic Theses and Dissertations 2010 - 2019

Throughout America’s history the call for laborers has been filled by influxes of immigrants. Coinciding with the arrival of the first non-Anglo Saxon immigrants were negative attitudes about them, as they were deemed inferior and classified as lowerranking “others” by the dominant culture that needed them. Thus, the cycle of need and resentment was born to be repeated throughout the Nation’s history. In the first half of the twentieth century a shift occurred in American public perception of, and attitudes towards, immigrant groups including eastern European Jews, Italians and the Irish among others. This shift was marked primarily in terms …

American National Identity And Discourses Of The Frontier In Early 20th Century Visual Culture, Chandra Ann Maldonado

Electronic Theses and Dissertations 2010 - 2019

This thesis examines the rise of image culture in the 1920’s and its impact on American national identity. I demonstrate that, perhaps surprisingly, the central figure in these debates was not a past or present prominent American but instead an indeterminate Other which is read in ambivalent ways and for varied purposes. It is the central claim of this project that in order to trace the modern American subject that emerges from the 1920s national rift, one must attend to the ways in which a felt need to view and position oneself in relation to “the Other” was essential to …

An Inquiry Into Scott's Instituional Theory, Marcus Bright

Electronic Theses and Dissertations 2010 - 2019

This dissertation evaluates the veracity of Richard Scott’s three pillars of institutionalization: regulative, normative, and cultural-cognitive. The test of his theory is whether the processes and practices within the environments of the three pillars can account for differences between academic performance and athletic performance in Miami-Dade County, Florida public schools. Scott’s model of institutionalization works better in predicting academic success than it does athletic success in the context of this study as evidenced by the majority of the findings coming from the scholastic realm. The primary methodological approach was to obtain publicly available measures of academic performance and resources for …

The “Closed World” Of The Exotic Leelo Singers: The Representation And Reception Of The Title Character And Other Seto Women In The Film Taarka, Kerli Kirch

Electronic Theses and Dissertations 2010 - 2019

This thesis utilizes a multi-perspectival cultural and media studies approach analyzing the production, filmic text, and reception of Taarka, the first film about Setos, that is advertised as a (docu)drama. However, the analysis shows that it can also be interpreted as an ethnographic film. It examines which intersecting identities related to Seto women are depicted in the film and whether audiences and critics recognize the power dynamics of these intersections. It also analyses how the Estonian cultural economic environment, the filmic text, audience comments and critics reviews reinforce or challenge hegemonies connected with these intersections. Drawing on the principles of …

Testing The Theory Of Dominant Institutionalized Policy Narratives Using Florida’S “Stand Your Ground” Discourse, Amanda Gillespie

Electronic Theses and Dissertations 2010 - 2019

Narratives are a very important part of public policy negotiations and deliberations. Public policy research has shown that policy narratives are manipulated to fit the motives of the creators and enforcers of that narrative (Stone, 2002). The creators and enforcers of these narratives use symbols, language, and other techniques to ensure that the narrative survives and dominates the political and social environment by becoming the favored policy prescription (Stone, 2002; Miller, 2012; Jones & McBeth, 2010; Schneider & Ingram, 1993). This study employs a qualitative content analysis to trace the genealogy of the following narratives that make up the “Stand …

The Correlations Between Ostds Sites And The Pollution Of The Surface Water Bodies In Broward County, Yvel Rocher

Electronic Theses and Dissertations 2010 - 2019

Sampling data of many surface water bodies in Broward County tend to reveal abnormal levels of bacterial concentrations for total coliform, Escherichia coli and Enterococcus. Given the presence of septic systems in geohydrologically sensitive areas throughout the County, several studies (Morin 2005 and Bocca 2007) suggested a correlation in the high bacterial densities and the septic sites.

The main objective of this thesis was to explore new measures of crime prevention on college campuses. Specifically, the efforts put forth in this study were to focus on understanding the problem of property theft of personal belongings on college campuses. The findings based on …

Time-Frequency Classification Of Gamma Oscillatory Activity In The Frontoparietal System During Working Memory, Tracy A. Romano

Electronic Theses and Dissertations 2010 - 2019

Working memory (WM) is a process that allows for the temporary and limited storage of information for an immediate goal or to be stored into a more permanent system. A large number of studies have led to the widely accepted view that WM is mediated by the frontoparietal network (FPN), consisting of areas in the prefrontal cortex (PFC) and posterior parietal cortex (PPC). Current evidence suggests that task specific patterns of neuronal oscillatory activity within the FPN play a fundamental role in WM, and yet specific spatio-temporal properties of this activity are not well characterized. This study utilized multisite local …

The Effect Of Acute Moderate-Intensity Continuous And High Intensity Interval Exercise On Serum Brain-Derived Neurotrophic Factor In Recreationally Trained Males, Thomas J. Mock

Electronic Theses and Dissertations 2010 - 2019

BDNF is a neurotrophin that enhances neural health and is increased by exercise. PURPOSE: To compare moderate continuous (MCE) and high-intensity interval exercise (HIE) effects on serum BDNF levels, and examine the relationship between BDNF and lactate. METHODS: Seven males completed a VO2peak test and two protocols on separate days, (MCE) 28 min at 60% Workrate max (WRmax) and (HIE) 28 min of intervals at 90%WRmax (10- 1 min intervals separated by 2 min of rest). Serum BDNF and lactate were determined prior, during, and following both protocols. RESULTS: BDNF levels (pg/mL) increased from baseline during HIE and MCE (p<.05). The BDNF response to HIE correlated with lactate for area under the curve (AUC) (r=0.901; P<0.05). CONCLUSION: HIE is an effective alternative to MCE at increasing BDNF. Additionally, lactate may act as a measure of intensity or a mediator of the BDNF response to exercise.

The Development Of Anonymous Giving In Relation To Ownership Understanding, Theory Of Mind, Empathy, And Differences In Relatedness, Karin Machluf

Electronic Theses and Dissertations 2010 - 2019

Prosocial behavior can be defined as any behavior that an individual engages in to benefit another (Eisenberg, Fabes, & Spinrad, 2006). Prosociality is not one homogenous trait, however, but is made up of three specific types of behavior: helping, cooperating, and sharing (or, more accurately, donating) (Tomasello, 2009). Although helping and cooperating are important to understanding prosocial development, giving behaviors might be particularly informative when trying to understand prosociality in young children as it poses a distinct problem for younger children (Tomasello, 1998). Research on proximate causes of prosocial behavior state that these behaviors are influenced by emotions of empathy …

Towards A Portal And Search Engine To Facilitate Academic And Research Collaboration In Engineering And, Villarreal Isaura Nathaly Bonilla

Electronic Theses and Dissertations 2010 - 2019

While international academic and research collaborations are of great importance at this time, it is not easy to find researchers in the engineering field that publish in languages other than English. Because of this disconnect, there exists a need for a portal to find Who’s Who in Engineering Education in the Americas. The objective of this thesis is to built an object-oriented architecture for this proposed portal.

Transformational Experiences Of African American Women: Their Critical Reflections As Former Migrants Who Evolved From Harvest Of Shame To Seeds Of Hope, Idell Mclaughlin-Jones

Electronic Theses and Dissertations 2010 - 2019

Narrative inquiry was the qualitative method utilized to collect stories related to former migrant African American females who transformed their lives from migrant workers and found alternative career paths. Sustained poverty among migratory workers created a disenfranchised culture of uneducated citizens. A large part of this labor force was women. It was expected that this culture of poverty would perpetuate itself through generations. The universal stereotypes associated with impoverished migrants were so ingrained that overwhelmingly the majority of migrants accepted a life of poverty as prophesy. However, some former migrant African American women defied odds and rose above the cumulative …
