Ecological Responses Of Seascape Heterogeneity, Dinorah H. Chacin

USF Tampa Graduate Theses and Dissertations

A core aim of landscape ecologists as well as conservation and management practices has been to understand how processes that structure communities vary as a function of landscape context. Landscape heterogeneity (i.e. landscape composition, configuration) and fine-scale habitat characteristics can influence ecological interactions across habitat patches at a range of scales. Therefore, the main objective of this work is to apply a landscape ecology perspective to understand how seascape heterogeneity can influence demographic rates, community patterns, and ecological processes. To accomplish this overall goal, I conducted a literature review on oyster reefs from a seascape ecology perspective (Chapter 1) and …

Lung Cancer Cells Survive Egfr Tki Exposure Through Upregulation Of Cholesterol Synthesis, Mark Howell

USF Tampa Graduate Theses and Dissertations

Lung cancer is the number one cause of cancer related death in both males and females. About 20% of all non-small cell lung cancer (NSCLC) patients are expected to harbor an epidermal growth factor receptor (EGFR) activating mutation. EGFR inhibitors have been shown to provide clinical benefits over chemotherapy for lung cancer patients with EGFR activating mutations. However, despite the initial clinical responses to these EGFR targeted therapies, long-term efficacy is not possible because acquired drug resistance hampers the effectiveness of these therapies. We found that a fiber inspired smart scaffold (FiSS) platform established in our laboratory allows growth of …

Construction Of G-Quadruplexes Via Self-Assembly: Enhanced Stability And Unique Properties, Ying He

USF Tampa Graduate Theses and Dissertations

This dissertation mainly contains three parts: 1) The construction of well-defined G8-octamers through the monomer conformational design. 2) The construction of cross-layer interactions in the G8-octamer for enhanced stability in H-bond competitive solvents. 3) Design and synthesis of 8-triazole guanosine with photoluminescent properties.

Through the structural conformational design, we have developed a new class of guanosine derivatives with modification on guanine (8-aryl) and ribose (2’,3’-isopropylidene). This unique design has led to the formation of the first discrete G8-octamer with structure characterized by NMR, MS and single crystal X-ray diffraction. The selectivity between monovalent (K+) and divalent cat-ions (Ba2+ and Sr2+) …

Identifying Employees Who Fit With Electronic Communication Styles, Britany Telford Mills

USF Tampa Graduate Theses and Dissertations

Electronic communication is no longer solely used by globally dispersed work teams. It is an integral part of today’s organizations whether they include remote workers or not. Therefore, it is important to understand how employees perceive electronic communication from their supervisor and the impact that perception has on the worker. Researchers have been adamant in the assertion that relationship-oriented communicated is better conducted face-to-face. The current study seeks to add to the existing body of research by (1) examining how the proportion of relationship-oriented communication that is electronic affects both subordinate perceptions of communication openness and subordinate job satisfaction, and …

First-Principles Simulations Of Materials Under Extreme Conditions, Kien Nguyen Cong

USF Tampa Graduate Theses and Dissertations

The investigation of materials at extreme conditions of high pressure and temperature (high-PT), has been one of the greatest scientific endeavors in condensed mater physics, chemistry, astronomy, planetary, and material sciences. Being subjected to high-PT conditions, materials exhibit dramatic changes in both atomic and electronic structure resulting in an emergence of exceptionally interesting phenomena including structural and electronic phase transitions, chemical reactions, and formation of novel compounds with never-previously observed physical and chemical properties. Although new exciting experimental developments in static and dynamic compression combined with new diagnostics/characterization methods allow to uncover new processes and phenomena at high P-T conditions, …

Current Situation And Future Prospects Of The Us Goat Industry, Steve Hart, Roger Merkel, Terry Gipson

Professional Agricultural Workers Journal

Abstract

The current demand for goat meat in the US outstrips domestic supply. There is great potential for industry growth in the meat and dairy sectors. Whereas fiber prices have improved, loss of animals and market resources, labor costs for shearing, and lack of animal genetic resources prevent growth in the short term. As producers age, there is opportunity for new producers to enter the marketplace. Significant challenges exist, like access to local markets and abattoirs, dewormer resistant parasites, and feed costs. Establishing goat feedlots can increase meat supply and industry commercialization. Technologies used for cattle will be expanded for …

Information Extraction From Primary Care Visits To Support Patient-Provider Interactions, Daniel Baruch Gutstein

College of Computing and Digital Media Dissertations

The extent of electronic health record systems usage in clinical settings has affected the dynamic between clinicians and patients and has thus been connected to physician morale and the quality of care patients receive. Recent research has also uncovered a correlation between physician burnout and negative physician attitudes electronic health record systems. In order to begin exploring the nature of the relationship between electronic health record usage, physician burnout, and patient care, it is necessary to first analyze patient-provider interactions within the context of verbal features such as turn-taking and non-verbal features such as eye-contact. While previous works have sought …

Innovating Green Stormwater Infrastructure For Nutrient Management: Long-Term Field And Modeling Studies Of Conventional And Modified Denitrifying Bioretention Systems, Emma V. Lopez-Ponnada

USF Tampa Graduate Theses and Dissertations

Urban stormwater and nutrient management are increasingly important topics to address globally, as coastal urbanization increases, disturbing the natural landscape, hydrology, and water quality. Untreated urban stormwater runoff carries pollutants that enter our waterways, such as rivers and marine environments, which serve as drinking water sources, recreational sites, and locations for economic livelihood. One pollutant and nutrient of concern for water quality is reactive nitrogen (N). Since pre-industrial time, reactive nitrogen has doubled from human activity. When found in excess in waterways, nitrogen causes an overabundant growth of algae, which can result in eutrophic and hypoxic conditions, impacting ecosystems, human …

Game-Based Science Education: Effect Of Aesthetics On Learning And Motivational Outcomes, Lucille Moon-Michel

USF Tampa Graduate Theses and Dissertations

The study of how aesthetic qualities of games affect student learning and motivational outcomes is an area in need of research in the instructional design field. Existing research in this realm is either lacking or does not provide comprehensive criteria for assessing its effectiveness on student outcomes. The purpose of this dissertation was to address this gap in literature by producing two articles based on a systematic literature review and a game-based learning quasi-experiment.

In Chapter Two, the systematic literature review gathered 44 studies published within the last decade to find trends in game design, visual game attributes, and research …

Finally. Ba/Bs Senior Exhibition, Emily Glowicki

B.A./B.S. Practicum Group Exhibit (ART 499)

My most recent work delves into the relationship of sculptural form and ceramic tradition and how we perceive amorphous beings that exhibit resonance of the recognizable. I’m interested in where we draw the line between form and function in ceramics and how we can explore both possibilities through the creation of ambiguous three-dimensional representation of these ideas.

My work addresses these ideas through both sculptural vessels and nonobjective forms that leave the realm of the vessel completely. This exploration of form and fluidity started with single word: torpid. Torpid, according to the dictionary, is an adjective to describe slow, sluggish, …

Beyond Spectator Sports: Scale Development And Validation For Mediated Sports Consumption, Min Jung Kim

Health, Exercise, and Sports Sciences ETDs

One apparent trend impacting spectator sports is the shift in sport fans’ consumption opportunities, having now gained many alternative formats to access sporting events. Sport fans are allowed intentionally and constantly to move from platform to platform and access content on demand. These substitute platforms, including home television, online streaming, social networking, sports bars, and movie cinema, are considered mediated sports consumption, alternative outlets to actual physical attendance of sporting events. As the phenomenon of mediated sports consumption has become a predominant means of spectating sports consumption practice, it is more important than ever to identify and understand how mediated …

Npr's Tiny Desk Concert Series: Vocalities Of Outrage And Acts Of Gaiety, Aubrie M. Powell

Music ETDs

The Tiny Desk concert series features live video-recorded performances of artists at the desk of NPR Music’s Bob Boilen, the series’ main host. This thesis interrogates NPR Music’s values and the ways artists both manifest and queer those ideals in performance. I argue, in light of the 2016 election, performers challenge NPR Music’s taste system through two modes of subversion. The first mode considers vocalities of outrage specifically in the performances of Saul Williams and the Drive-By Truckers. These performers shift their social positions in expressions of outrage through vocality—as the embodied materiality of the voice and its constructed meanings …

Using Natural Phenomena To Study The Ionosphere, Joseph Benjamin Malins

Physics & Astronomy ETDs

This dissertation explores novel techniques for observing the ionosphere using natural signals. The ionosphere is a region of plasma hundreds of kilometers above the Earth that affects communication and remote sensing applications across the world. Traditional techniques for observing the ionosphere involve using man made radio signals, either to reflect the signal at HF frequencies or to pass several signals through the ionosphere and compare the difference the ionosphere makes in the signals. However, such techniques are limited by the ability of equipment to produce these signals and by the numerous laws and regulations governing transmission of signals in the …

Cordycepin Inhibits Human Ovarian Cancer By Inducing Autophagy And Apoptosis Through Dickkopf-Related Protein 1/Β-Catenin Signaling, Hyun-Jin Jang, Kyeong Eun Yang, In-Hu Hwang, Yang Hoon Huh, Dae Joon Kim, Hwa-Seung Yoo, Soo Jung Park, Ik-Soon Jang

School of Medicine Publications

Cordycepin, the major active component from Cordyceps militaris, has been reported to significantly inhibit some types of cancer; however, its effects on ovarian cancer are still not well understood. In this study, we treated human ovarian cancer cells with different doses of cordycepin and found that it dose-dependently reduced ovarian cancer cell viability, based on Cell counting kit-8 reagent. Immunoblotting showed that cordycepin increased Dickkopf-related protein 1 (Dkk1) levels and inhibited β-catenin signaling. Atg7 knockdown in ovarian cancer cells significantly inhibited cordycepin-induced apoptosis, whereas β-catenin overexpression abolished the effects of cordycepin on cell death and proliferation. Furthermore, we found …

Mini-Actors, Mega-Stages: Examining The Use Of Theatre Among Children And Youth In U.S. Evangelical Megachurches, Carla Elisha Lahey

LSU Doctoral Dissertations

How do children and youth first encounter the performing arts? While schools may stand out as an obvious answer, a recent study conducted by the U.S. Department of Education shows that the percentage of public schools offering theatre classes dropped at both the primary and secondary level from 2000-2010 (Brenchley). Yet, even as arts offerings experience a decline in some public schools, many students are being introduced to performance through another venue – the evangelical megachurch.

Since the birth of the church growth movement in the 1970s, megachurches (defined as Protestant congregations that average at least 2,000 weekly attendees) have …

Social Justice Through Social Media: The Use Of Twitter As A Tool For Activism In The #Metoo #Blacklivesmatter Era, Laura L. Coleman

LSU Master's Theses

This study focuses on social justice and how people on Twitter chose to talk about it. The rise of social media has allowed Twitter users to speak more freely in more spaces than one. The study compared two different sexual assault cases between Judge Brett Kavanaugh and Professor Christine Blasey; and Virginia’s Lt. Governor Justin Fairfax and Vanessa Tyson. Applying the social responsibility theory, which allows free press without any censorship, I then can see the tone of which Black Twitter users have when talking about two separate sexual assault cases. This study compares the use of the #BlackTwitter hashtag …

Brett Kavanaugh Vs. The Exonerated Central Park Five: Exposing The President's "Presumption Of Innocence" Double Standard, Sofia Yakren

Journal of Civil Rights and Economic Development

(Excerpt)

In the service of Justice Brett Kavanaugh’s confirmation to the United States Supreme Court, the President of the United States (and Republican Senators) both misappropriated and further eroded the already compromised concepts of due process and presumption of innocence. This Essay uses the prominent “Central Park Five” case in which five teenagers of color were wrongly convicted of a white woman’s widely-publicized beating and rape to expose the President’s disparate use of the presumption along race and status lines. This narrative is consistent with larger systemic inequities that leave poor black and brown criminal defendants less likely to benefit …

Hearing Women: From Professor Hill To Dr. Ford, Stephanie M. Wildman

Journal of Civil Rights and Economic Development

(Excerpt)

One of the recent traumas, another skirmish in today’s civilian conflict over what kind of society America will be, arose from Dr. Christine Blasey Ford’s testimony about sexual assault she had endured. Her composed, measured statement during the nowJustice Brett Kavanaugh confirmation hearing exemplified bravery in the face of adversity. The Senate and the nation’s response to her testimony underscored the high stakes in the ongoing ideological conflict, beyond the obvious prize of a Supreme Court seat. Constituents in the current ideological battle had differing reactions to Ford’s testimony and to this hearing, reflecting a range of views about …

"I Still Like Smear": The Senate Judiciary Committee's Obstructing Politics Surrounding The Kavanaugh Hearing And A Solution To The Chaos That Ensued, Frank J. Tantone

Journal of Civil Rights and Economic Development

(Excerpt)

The incredible events and raucous behavior by members of the Committee that colored Justice Kavanaugh’s confirmation process rose to a level of intensity and virulence never seen before in this specific area of American government and politics. Nevertheless, the most analogous situation that somewhat closely reflects the events that transpired in 2018 occurred seventeen years earlier. President George H.W. Bush, on July 1, 1991, nominated then District of Columbia Circuit Court Judge, Clarence Thomas, to replace Justice Thurgood Marshall on the Supreme Court. Thomas’s confirmation hearing was also opposed from the outset but by civil rights and feminist organizations …

How The Boogeyman Saved Brett Kavanaugh, Cathren Page

Journal of Civil Rights and Economic Development

(Excerpt)

We love to hate these boogeymen. When the societal narrative creates these invisible boogeymen, people can pour their rage against sexual abuse into these faceless antagonists. At the same time, the enraged survivors and protectors avoid conflicts with family, neighbors, colleagues, and social acquaintances who might actually commit or enable sexual abuse. We can dodge sticky questions regarding how a churchgoer, a judge, or an Ivy Leaguer could have committed a heinous act. The survivors can avoid all the victim-blaming backlash, threats of violence, and invalidation that accompanies reporting a sexual offense. Moreover, having less power on their own, …

The Master's Tools Will Never Dismantle The Master's House: Kavanaugh's Confirmation Hearing And The Perils Of Progressive Punitivism, Hadar Aviram

Journal of Civil Rights and Economic Development

(Excerpt)

This essay proceeds in four parts. In Part I, I problematize the idea of the accused’s demeanor as evidence of guilt, remorse, or entitlement, arguing that we tend to overestimate our ability to deduce internal states of mind from people’s behavior and expressions. Part II assesses the potential (or lack thereof) of public performances of reckoning to produce a valuable expression of remorse, discussing the value of contingent apologies. Part III expands the framework to examine the way our politically fractured field responds to partisan efforts to excoriate culprits, arguing that “starting a national conversation” on the basis of …
