Yogurt Cultures Survive Upon Exposure To Two Antimicrobials And Streptococcus Thermophilus St-M5 Acquired Resistance To Both Antimicrobials, Maria Carolina Vives Habeych

LSU Master's Theses

Different antimicrobials are added in the manufacturing of dairy products such as flavored yogurts and processed cheese. Potassium Metabisulfite (PM) and Potassium Nitrite (PN) have been reported to have antimicrobial effect on pathogenic microorganisms such as Clostridium botulinum and Listeria monocytogenes. Yogurt is known for its health benefits, due to the presence of cultured bacteria. PM and PN are not commonly used in the dairy industry hence it would be interesting to study their influence in yogurt culture bacteria. The objectives of this study were: 1. to elucidate the influence of PM and PN at various concentrations, on the growth …

From The Viewbook To Facebook: A Content Analysis Of Universities' Facebook Posts To Measure Organization-Public Relationships, Aariel Roxanne Charbonnet

LSU Master's Theses

This study examined StudentAdvisor.com's top 25 social media colleges to determine the ways in which these universities communicated with their various publics on Facebook. Using Hon and Grunig's models of public relations as frameworks, a quantitative content analysis was performed. The study considered each individual post on the universities' Facebook walls (n=709) over the course of a three-week period. The study's research questions were based on whether the posts promoted Hon and Grunig's relationship indicators, as well as what public relations models the posts resembled. Results indicated that posts were least likely to resemble the two-way symmetrical model and seldom …

Cluster Based Jamming And Countermeasures For Wireless Sensor Network Mac Protocols, David Trammell

LSU Doctoral Dissertations

A wireless sensor network (WSN) is a collection of wireless nodes, usually with limited computing resources and available energy. The medium access control layer (MAC layer) directly guides the radio hardware and manages access to the radio spectrum in controlled way. A top priority for a WSN MAC protocol is to conserve energy, however tailoring the algorithm for this purpose can create or expose a number of security vulnerabilities. In particular, a regular duty cycle makes a node vulnerable to periodic jamming attacks. This vulnerability limits the use of use of a WSN in applications requiring high levels of security. …

Playing The Christ Card: Courting Christians Through Religious Appeals In Political Campaigns, Matthew Lee Thornton

LSU Doctoral Dissertations

In spite of a corpus of work over the last three decades acknowledging the centrality of religion in politics, (see e.g. Hunter, 1991; Layman, 2001; Putnam & Campbell, 2010; Wuthnow, 1988), there remains a scarcity of research examining the consequences of religious communication in political campaigns. The current study fills this void through an empirical exploration of the effects of religious campaign appeals on prospective voters. Specifically, this interdisciplinary investigation develops a theoretical framework and subsequent expectations as to how religious appeals are likely to activate individual religiosity thereby influencing the formation of political attitudes. Hypothesized expectations are then tested …

Early Voting In The 2004 Presidential Election, James Michael Siira

LSU Doctoral Dissertations

The addition of early voting laws has led to the many changes in the US political system. In this dissertation I examine early voting early voting in a number of different contexts. First, how early voting fits in with the larger issue of voter turnout in the U.S. Second, why some states have early voting policies and other states choose to not have those policies. Third, how state-level political parties view the option to cast an early vote. Fourth, the differences between early voters, election day voters, and non-voters. Fifth, what are the determents of casting an early ballot. Sixth, …

Visual Translation: A New Way To Design A Chinese Typeface Based On An Existing Latin Typeface, Yifang Cao

LSU Master's Theses

The visual consistency of branding makes a significant difference when successfully introduced to another culture. My study focuses on how to facilitate a smooth visual transition in western branding from Latin letters to Chinese characters. To move beyond traditional Chinese type design, Visual Translation introduces a new method for designing Chinese typefaces using existing Latin typefaces. This web-based educational tool seeks to help Chinese graphic design students and type enthusiasts, with emphasis on designers who are working in a cross-cultural environment to maintain visual consistency for branding.

Inefficient Replication Reduces Reca-Mediated Repair Of Uvdamaged Plasmids Introduced Into Competent Escherichia Coli, Harout Arthur Jeiranian, Charmain T. Courcelle, Justin Courcelle

Biology Faculty Publications and Presentations

Transformation of Escherichia coli with purified plasmids containing DNA damage is frequently used as a tool to characterize repair pathways that operate on chromosomes. In this study, we used an assay that allowed us to quantify plasmid survival and to compare how efficiently various repair pathways operate on plasmid DNA introduced into cells relative to their efficiency on chromosomal DNA. We observed distinct differences between the mechanisms operating on the transforming plasmid DNA and the chromosome. An average of one UV-induced lesion was sufficient to inactivate ColE1-based plasmids introduced into nucleotide excision repair mutants, suggesting an essential role for repair …

Uvrd Participation In Nucleotide Excision Repair Is Required For The Recovery Of Dna Synthesis Following Uv-Induced Damage In Escherichia Coli, Kelley Nicole Newton, Charmain T. Courcelle, Justin Courcelle

Biology Faculty Publications and Presentations

UvrD is a DNA helicase that participates in nucleotide excision repair and several replication-associated processes, including methyl-directed mismatch repair and recombination. UvrD is capable of displacing oligonucleotides from synthetic forked DNA structures in vitro and is essential for viability in the absence of Rep, a helicase associated with processing replication forks. These observations have led others to propose that UvrD may promote fork regression and facilitate resetting of the replication fork following arrest. However, the molecular activity of UvrD at replication forks in vivo has not been directly examined. In this study, we characterized the role UvrD has in processing …

Open Justice: Concepts And Judicial Approaches, Emma Cunliffe

All Faculty Publications

Recent years have seen an increase in the number and scope of non-publication orders and other limits on open justice, an increase in the number of statutes that regulate or threaten open justice, and the articulation of an Australian constitutional principle (of institutional integrity) that has the potential to protect some aspects of open justice. The purposes and values of open justice are, however, rarely examined in a comprehensive or theoretically-informed manner. This article provides a theory of open justice which accounts for its heterogeneous nature. Australian judicial approaches to the substance, limits, and constitutional dimensions of open justice are …

Rescuing The Dignitary Torts From The Constitution, Cristina Carmody Tilley

Faculty Publications

The rights of individuals to recover for dignitary torts has been withering for the past forty years, since the Supreme Court constitutionalized the state common law tort of defamation in New York Times v. Sullivan in 1964. The Court announced in that case that the First Amendment required it to impose high standards for individual defamation claims in order to protect robust speech. As that principle has taken hold, it has in effect squeezed the rights of individuals to recover for invasion of privacy and intentional infliction of emotional distress as well as defamation. Just last Term, the Court held …

What Is In A Name? The Hermeneutics Of Authorship Analysis Concerning Colossians, Nijay Gupta

Faculty Publications - Portland Seminary

Pauline scholars, especially in the last century, have been almost evenly divided on whether they consider Colossians to be genuinely written by Paul or by someone else in his name. Through an exploration of the commentaries of eight key scholars on Colossians, this study examines the hermeneutics of authorship analysis in order to determine the key factors involved and how they are weighed. For the study of the authorship of Colossians to move forward in a productive way, a number of yet-understudied issues must be addressed and closely researched. In the meantime, tentativeness in conclusions is the most reliable stance.

Behavioral Factors Influencing Health Outcomes In Youth With Type 1 Diabetes, Jessica C. Kichler, Ashley Moss, Astrida S. Kaugars

Psychology Faculty Research and Publications

The Pediatric Self-Management Model provides an overview of how behavioral factors influence children’s chronic medical illnesses. This general framework is used to organize the present review of how self-management behaviors, contextual factors, and processes impact health outcomes for adolescent youth with type 1 diabetes. Adherence has been widely studied in the diabetes literature, and there are consistent findings demonstrating associations between aspects of self-management, adherence, and metabolic control, yet there are still equivocal approaches to adherence assessment methodology (e.g. global versus specific measures). Metabolic control is a hallmark health outcome for youth with type 1 diabetes, but additional outcomes need …

What Is Good Enough For Mobile System Evaluation: A Comparison Of Laboratory And Field Setting, Yao Wang

Theses

There is no consensus on whether field tests are necessary in evaluating mobile systems. Empirical studies have compared evaluations in the laboratory environment and field environment, but they provide different results due to the lack of consistent testing environments. Contributing to mobile system evaluation exploration, this study conducts a comparative analysis between laboratory study and field study by recreating the natural context in the laboratory and using recording software embedded in the mobile device. The results show that involving natural use context in a controlled testing environment identifies more usability problems than a complex field test, when the objective is …

Determination Of Chromaticness Difference Tolerance Of Offset Printing By Means Of Simulation, Jing Sheng

Theses

Printing quality can be defined as conformance to specifications. ISO

12647-2 (2004), the standard for offset lithographic printing, specifies solid, TVI and mid-tone spread as conformance metrics. The revision of ISO 12647-2 (2010) embraces ΔCh as a new metric for grey reproduction assessment. In order to complete the revision, both the test method and the tolerance must be specified. In his presentation at TC130 in April 2011, Chung proposed a "three triplets' method as input to the grey reproduction assessment. He also proposed the use of G7 pass/fail criteria as the criteria to determine the tolerance in terms of ΔCh. …

On The Skewness Of Order Statistics With Applications, Subhash C. Kochar, Maochao Xu

Mathematics and Statistics Faculty Publications and Presentations

Order statistics from heterogenous samples have been extensively studied in the literature. However, most of the work focused on the effect of heterogeneity on the magnitude and dispersion of order statistics. In this paper, we study the skewness of order statistics from heterogeneous samples in the sense of star order. The main results extended the results in Kochar and Xu (2009, 2011). Examples and applications in statistical inference are highlighted.

Beyond The Backlash: Muslim And Middle Eastern Immigrants' Experiences In America, Ten Years Post-9/11, Gregory J. Mills

USF Tampa Graduate Theses and Dissertations

In this thesis, I explore the perceived character of Islamophobia in American society, and how Islamophobia is embedded in the everyday lived experiences and identity negotiations of a sample of Middle Eastern immigrants, ten years post-9/11. Data consist of 13 qualitative interviews with first-generation Middle Eastern immigrants, including Muslims, Christians, and those who claim no religion. Findings suggest that perceived discrimination and cultural hostility vary across both gender and religion. Women who cover with the hijab perceive far more discrimination and humiliating experiences than men or women who do not cover in the sample. Iranians also receive extremely poor treatment, …

"You Understand Me Now": Sampling Nina Simone In Hip Hop, Amanda Renae Modell

USF Tampa Graduate Theses and Dissertations

The overarching goal of this research is to explicate the implications of hip hop artists sampling Nina Simone's music in their work. By regarding Simone as a critical social theorist in her own right, one can hear the ways that hip hop artists are mobilizing her tradition of socially active self-definition from the Civil Rights/Black Power era(s) in the post-2000 United States. By examining both the lyrics and the instrumental compositions of Lil Wayne, Juelz Santana, Common, Tony Moon, Talib Kweli, Mary J. Blige and Will.I.Am, G-Unit and Timbaland, and bearing in mind the intersecting oppressions of race, class, gender, …

Beyond Practice And Constraint: Toward Situating Female Sexual Agency On St. Croix, Usvi, Jamae F. Morris

USF Tampa Graduate Theses and Dissertations

Women are shaped by the social structure, but they are not simply passive products. They act. They respond. They pursue. This holds true for many aspects of women's complex and dynamic lives, including their sexual health. Daily, women negotiate social expectations, individual proclivities and desires, and the need to provide for themselves and their families. Through the use of ethnographic methodology, focusing on three major social pillars--the regulation of the female body, the organization of social space, and the structuring of gender--this investigation, based on the island of St. Croix, USVI, seeks to offer an ethnographic assessment of women's attempts …

Understanding Involuntary Job Loss Among Former Newspaper Staff Photographers, Ryan K. Morris

USF Tampa Graduate Theses and Dissertations

This study examines former newspaper photographers' experience with being laid-off from their staff positions. The purpose was to identify emerging themes within the context of involuntary job loss, job satisfaction, and occupational identity via interviews with 8 photojournalists who experienced the phenomenon of being laid-off. The newspaper industry has long been considered both the starting point for young and aspiring photojournalism careers and the most consistent and stable venue for an income. Yet recent changes in the media landscape, particularly economic stress on traditional business models and rapid adoption of digital technology sway the occupational future of photojournalism within newsrooms. …

The Indigenous Movement And The Struggle For Political Representation In Bolivia, Angelica T. Nieves

USF Tampa Graduate Theses and Dissertations

The theme of ethnic identity in politics is gaining importance in countries such as Bolivia, where people recently elected their first indigenous President. The Indigenous movement has been able to incorporate themselves in the state apparatus and have produced new political policies and constitutional instruments. They represent an alternative to the "white" political elites who governed them for many decades. This study analyzes the dynamics within the Indigenous social movement in Bolivia and how they reinforced a composite vision of a participatory democratic society through political representation. The results of this participation (and, moreover, political representation) can be seen in …

Global Csr And Photographic Credibility: Exploring How International Companies Portray Efforts Through Photographs In Csr Reports, Janel Lynn Norton

USF Tampa Graduate Theses and Dissertations

We are living in the age of the visual. Imagery is an important element in constructing and deriving meaning through symbols, colors, and context. Images may hold persuasive power, be used as evidence, or simply provide a moment of beauty. Organizations rely on photographs to help them convey an image to their stakeholders within annual reports. Telling an organizations' story through photographs has become an intrinsic part of their efforts to convey sustainability. We live in the age of transparency, and organizations that construct an image that is not truthful will face consequences in today's socially connected and conscious world. …

Occurrence, Toxicity, And Diversity Of Pseudo-Nitzschia In Florida Coastal Waters, Sheila O'Dea

USF Tampa Graduate Theses and Dissertations

Domoic acid (DA), a potent neurotoxin that has the potential to cause amnesic shellfish poisoning (ASP), is produced by members of the marine diatom genus Pseudo-nitzschia. Outbreaks of ASP in humans and of DA poisoning in birds and marine mammals have been reported across the United States and Canada since the late 1980's. Pseudo-nitzschia species can be extremely abundant in Florida waters, with densities often exceeding 10⁶ cells/L, and sometimes exceeding 10⁷ cells/L. Based on preliminary data, it is evident that at least nine species of Pseudo-nitzschia are found in Florida coastal waters. At least six of …

Macroencapsulation Of Phase Change Materials For Thermal Energy Storage, Swetha Pendyala

USF Tampa Graduate Theses and Dissertations

The use of a latent heat storage system using phase change materials (PCMs) is an effective way of storing thermal energy. Latent heat storage enables high-energy storage density which reduces the footprint of the system and the cost. However, PCMs have very low thermal conductivities making them unsuitable for large-scale use without enhancing the effective thermal conductivity. In order to address, the low thermal conductivity of the PCMs, macroencapsulation of PCMs has been adopted as an effective technique. The macroencapsulation not only provides a self-supporting structure of PCM and separates the PCM from thermal fluids but also enhances the heat …

The New Materialism: Althusser, Badiou, And Zizek, Geoffrey Dennis Pfeifer

USF Tampa Graduate Theses and Dissertations

This dissertation traces the post-Marxist and materialist positions of two leading contemporary European thinkers: Slavoj Zizek and Alain Badiou. These thinkers, I argue, collectively offer a way between the traditional Hegelian Marxist's overarching meta-narrative of a necessary evolution from worse to better, and the post-modern pessimism of a lack of possibility for such a social evolution. It is this middle path, offered by these two thinkers, that this dissertation seeks to explore and further explain. The focal point of this dissertation is the type of philosophical materialism that is collectively offered by Badiou and Zizek, what I call the "New …

The War Of The Roses: Ritual Shaming, Morality, And Gender On The Radio, Jill M. Potkalesky

USF Tampa Graduate Theses and Dissertations

In this thesis, I show how a current radio program, War of the Roses, acts as a ritual of shaming that affirms the social order as moral order, involving moral condemnation, degradation of social identity, and public embarrassment (Goffman, 1956, 1967; Turner 1987). I use discourse analysis (DA) (e.g., Bergmann, 1998; Tracy, 2001; Tracy & Mirivel, 2008) and membership categorization analysis (Baker, 2000; Roulston, 2001) to examine eight transcripts from multiple versions of the War of the Roses radio program across the country. The basic premise of the radio program War of Roses involves a "caller" who suspects her or …
