A Clay Mineral Provenance Study Of The Northern Pandora Trough Continental Margin, Gulf Of Papua, Ashley Len Howell

LSU Master's Theses

X-ray diffraction mineralogy of western-, central-, and eastern-derived fluvial sediments within the Gulf of Papua exhibits distinct and mixed clay mineral assemblages. These mineral assemblages allow for a better understanding of how a thick muddy continental margin shelf-edge depocenter in the eastern Gulf of Papua of latest Pleistocene/early Holocene age formed, as well as connections between terrestrial sediment delivery and evolution of deep-sea deposits in this region. Modern clay mineralogy reveals a high to low gradation of illite/smectite values from the western to eastern Gulf of Papua (Slingerland et al., 2008a), which is applied to the recent past for provenance …

Design Flood Elevations Beyond Code Requirements And Current Best Practices, Frank H. Bohn

LSU Master's Theses

In the United States, nearly 9 million people, 3.0% of the population, live in areas subject to the 1% annual chance (100-yr) coastal flood hazard. New construction and substantial improvements in coastal high hazard areas require structures to be elevated above the design flood elevation (DFE), without the use of fill (Bellomo et al. 1999). Building code requirements for flood elevation are linked to the National Flood Insurance Program (NFIP) insurance policies, and represent the minimum requirement for building elevation. Current elevation procedures are limited to the 100-year base flood elevation with minimal guidance beyond the 100-year elevation in many …

Reef Fish Demographics On Louisiana Artificial Reefs : The Effects Of Reef Size On Biomass Distribution And Foraging Dynamics, Kirsten A. Simonsen

LSU Doctoral Dissertations

Understanding the role that habitat plays in the life history of reef-associated fishes is particularly significant given the dramatic increase in the number of artificial reefs deployed in coastal ecosystems over the past 50 years. In the Gulf of Mexico, the oil and gas industry has added a significant amount of structure to the Louisiana continental shelf, creating the largest de facto artificial reef deployment area in the world. Noting their usefulness as fish habitat, the Louisiana Artificial Reef Program was established to convert decommissioned platforms into artificial reefs. However, very little quantitative information exists on how these habitats affect …

Economics And The Bible, Roger S. Nam

Faculty Publications - Portland Seminary

At its essence, economics is the study of how societies make decisions on the allocation of limited resources. Whether subsistence, capitalist, socialist, or totalitarian, each society faces complex choices regarding the distribution of goods and utilities. In making such choices, economics involves the study of the various allocation processes such as production, consumption, exchange, forecasting, scarcity, and risk. But in all of these activities, economics is observable only through human behavior. Consequently, efforts to isolate economic behavior from social spheres are heuristic at best, misleading at worst. Economic decisions reflect deeper ideological values, hierarchies, and positions of power, often revealed …

Facebook Policy And User Knowledge: Self-Inflicted Totalitarianism, Richard Rockelmann Jr

Theses

Facebook has become an integral part of digital natives lives. As the technology is used more often, trust in the service increases. The unfortunate reality: people misinterpret trust by assuming anything can be said and done on this popular social media outlet. The problem of course is the fact that Facebook is a business that is fueled by sharing information to both third parties and other people. Their business scheme, combined with users misunderstanding of what power the policies have over them has the potential to incriminate and destroy students future they are working so hard to obtain. Are people …

Effect Of Microwave Heating On The Migration Of Additives From Ps, Pp And Pet Container Into Food Simulants, Ruoyin Cai

Theses

Microwave food packaging has become a tremendous element in the food manufacturing process. The purpose of any food packaging regulations concerned with the safety of the food is to control and limit the migration of substances from the packaging into the food. The main objective of this thesis is to test three different microwaving packaging materials that are the most common material in the market, viz. polystyrene (PS), polypropylene (PP), and polyethylene terephthalate (PET), migrated into four food simulant solutions. Four different simulant solutions were used based on the food type and FDA recommendations and regulations. These food simulants include …

The Development And Validation Of The Physical Appearance Comparison Scale-Revised (Pacs-R), Lauren M. Schaefer

USF Tampa Graduate Theses and Dissertations

The Physical Appearance Comparison Scale (PACS; Thompson, Heinberg, & Tantleff, 1991) is a widely used 5-item measure that assesses an overall tendency to compare one's own appearance to the appearance of others in social situations. Research using the PACS and other measures of appearance comparison has shown this construct to be related to higher levels of body dissatisfaction and eating pathology. However, the measure is limited in that it only assesses comparison tendencies within a narrow range of social contexts and body sites. In the current investigation, the PACS was revised to examine a broader range of social contexts (e.g., …

Utilizing Habit Reversal And Contingency Contracting To Impact Eating Habits With Obese Individuals, Christopher Thomas Scull

USF Tampa Graduate Theses and Dissertations

One of the most difficult set of behaviors for individuals to engage in is weight management. The United States boasts an astonishing 35% obesity rate in adults while children show almost a 20% obesity rate. These statistics identify the importance of developing effective methods to help change an individual's eating habits. There are many eating habits that may contribute to an individual gaining or losing weight over a period of time. Simplified habit reversal (SHR) has an impressive history in shaping desirable responses to compete with many different types of habitual behaviors. The present study extended the SHR procedure to …

Turning Water Into Wine: The Political Economy Of The Environment In Southern California's Wine Country, Jason Simms

USF Tampa Graduate Theses and Dissertations

This dissertation examines questions of water sustainability in contexts of wine production and state-led neoliberal development in the Temecula Valley, southern California, where wine tourism is at present being harnessed as an engine of economic growth. Natural and anthropogenic forces, such as global climate change, desertification, urban development, and the marketization and commodification of natural resources, affect the distribution and availability of water throughout the globe. As a result, the use of water, and associated political and environmental processes and consequences, in the production of global commodities, including wheat, citrus, and coffee, recently have come under increased scrutiny. Given wine's …

Refiguring Indexicality: Remediation, Film, & Memory In Contemporary Japanese Visual Media, Janine Marie Villot

USF Tampa Graduate Theses and Dissertations

Through an analog between film and memory, I argue contemporary Japanese visual media constantly remediates this relationship in order to develop a more inclusive, plastic indexicality that allows media without direct material contiguity access to an indexicality not typically attributed to it. Amidst the early twenty-first century shift from old, mechanical media to new, electronic media, each Japanese text engages the West through intercultural discourses and intracultural responses, just as Japan has continually encountered the West since its forced opening by Commodore Perry in 1853. The plasticized indexicality figured by contemporary Japanese visual media implies the plastic nature of abstracted …

Intermediate-Level Chinese Language Learners' Social Communication In Chinese On Facebook: A Mixed Methods Study, Shenggao Wang

USF Tampa Graduate Theses and Dissertations

With Facebook widely embraced by college students, exploring its educational uses has piqued both educators' and researchers' interest (Mills, 2011; Reinhardt & Zander, 2011; Thorne, 2011). Drawing on a functional perspective of language use, this study explored what kind of language functions intermediate-level Chinese language learners performed when they conducted social communication in Chinese on Facebook and whether conducting weekly social communication in Chinese on Facebook impacted their writing ability. A mixed methods design was adopted. A qualitative approach addressed discourse functions of student communication on Facebook. The qualitative data were mainly collected from nine students' Facebook posts during one …

From Upper Volta To Burkina Faso: A Study Of The Politics Of Reaction And Reform In A Post-Colonial African Nation-State, 1960-1987, Bryan J. Williamson

USF Tampa Graduate Theses and Dissertations

Abstract (from thesis text)

From Upper Volta to Burkina Faso, is the study of the politics of reaction and reform in a post-colonial nation-state of Burkina Faso. Since its independence from France on 5 August 1960 to 15 October 1987, Burkina Faso, the "land of the upright" people, has experience five changes in government. All of the coups that took place in this twenty-seven year period were reactionary and reforming. However, the most memorable reforms arrived after the coup of 4 August 1983 which gave rise to a youthful president in a thirty-three year old Captain Thomas Sankara. As the …

"Of That Transfigured World" : Realism And Fantasy In Victorian Literature, Benjamin Jude Wright

USF Tampa Graduate Theses and Dissertations

"Of That Transfigured World" identifies a generally unremarked upon mode of nineteenth-century literature that intermingles realism and fantasy in order to address epistemological problems. I contend that works of Charles Dickens, Charlotte and Emily Brontë, Walter Pater, and Oscar Wilde maintain a realist core overlaid by fantastic elements that come from the language used to characterize the core narrative or from metatexts or paratexts (such as stories that characters tell). The fantastic in this way becomes a mode of interpretation in texts concerned with the problems of representation and the ability of literature to produce knowledge. Paradoxically, each of these …

Reaction Formation And Homophobia: An Erp Examination, Krista Grace Yakub

USF Tampa Graduate Theses and Dissertations

Homophobia in men may be, in part, due to reaction formation rooted in unacceptable same-sex attraction. Previous studies have not confirmed a covert same-sex attraction in homophobic men, which is necessary for a reaction formation theory of homophobia. This study sought to reveal possible covert same-sex attraction in homophobic men. In this study, heterosexual and homosexual male erotic images were presented in a passive S1/S2 stimulus prediction design to 48 self-identified heterosexual participants, grouped by homophobia. Three event-related potential responses related to valenced emotional processing were examined: the medial frontal negativity (MFN), the late positive potential (LPP), and the positive …

The objective of this study was to apply a variety of traditional and novel statistical methods to analyze data from the National Data Buoy Center, which records among other variables barometric pressure, atmospheric temperature, water temperature and dew point temperature. The analysis included attempts to better describe and model the data as well as to make estimations for certain variables. The following statistical methods were utilized: linear regression, non-response …

A Model Of Positive Sequential Dependencies In Judgments Of Frequency, Jeffrey Scott Annis

USF Tampa Graduate Theses and Dissertations

Positive sequential dependencies occur when the response on the current trial n is positively correlated with the response on trial n-1. This was recently observed in a Judgment of Frequency (JOF) task (Malmberg and Annis, 2011). A model of positive sequential dependencies was developed in the REM framework (Shiffrin & Steyvers, 1997) by assuming that features that represent the current test item in a retrieval cue carry over from the previous retrieval cue. To assess the model, we sought a set of data that allows us to distinguish between frequency similarity and item similarity. Therefore, we chose to use a …

Exploring Potential Risk Factors Of Fetal Origins Of Diabetes: Maternal Stressors During Pregnancy And Birth Outcomes Among Women In A Hospital In The Municipality Of Caguas, Puerto Rico, Juan Pablo Arroyo

USF Tampa Graduate Theses and Dissertations

Puerto Rico has the highest prevalence of type 2 diabetes, low birth-weight, and the second highest prevalence of preterm-birth in all the U.S. and its non-incorporated territories. These conditions are related. Birth-weight at both ends of the spectrum and preterm-birth are associated with an increased risk for developing type 2 diabetes and immune-inflammatory dysregulations. Maternal psychosocial stressors during pregnancy have also been recognized as potential risk factors for type 2 diabetes, and have been consistently associated with preterm-birth and low birth-weight across populations. Current evidence points toward epigenetic fetal metabolic-programming as the mechanism that underlies the increased risk for the …

An Investigation Of Ocb Demands And Workplace Behaviors, Jeremy Allen Bauer

USF Tampa Graduate Theses and Dissertations

Abstract

The current study investigated the relationship between demands for organizational citizenship behaviors and future displays of organizational citizenship and counterproductive work behaviors. Such demands are conceptualized as workplace conditions that make it difficult for employees to complete their job (i.e., organizational constraints), performance failures of coworkers such as incomplete or incorrectly done tasks (i.e., coworker failure) and direct or indirect request from the supervisors to commit more organizational citizenship behaviors (i.e., supervisor pressure). Additionally, the effect of negative affectivity, hostile attribution bias, attributions of blame, and target specific scales of workplace behaviors were investigated. The design of the current …

Structure, Dynamics, And Evolution Of The Intrinsically Disordered P53 Transactivation Domain, Wade Michael Borcherds

USF Tampa Graduate Theses and Dissertations

in numerous disease states, including cancers and neurodegenerative diseases. All proteins are dynamic in nature, occupying a range of conformational flexibilities. This inherent flexibility is required for their function, with ordered proteins and IDPs representing the least flexible, and most flexible, respectively. As such IDPs possess little to no stable tertiary or secondary structure, they instead form broad ensembles of heterogeneous structures, which fluctuate over multiple time scales. Although IDPs often lack stable secondary structure they can assume a more stable structure in the presence of their binding partners in a coupled folding binding reaction.

The phenomenon of the dynamic …

Supporting Speech-Language Pathologist Evidence-Based Practice Use: A Mixed-Methods Study In Skilled Nursing Facilities Within The Promoting Action On Research Implementation In Health Services Framework, Natalie Franko Douglas

USF Tampa Graduate Theses and Dissertations

As the management of dementia is a significant public health concern, efforts to increase access to effective treatments to a greater number of residents with dementia in skilled nursing facilities (SNFs) are warranted. The treatment addressed in this study, non-electronic external memory aids, is an evidence-based practice that has been found to increase positive communicative interactions and decrease negative behavioral problems of residents with dementia in SNFs.

Although use of memory aids is recommended, there are significant barriers such as lack of time and resources that inhibit the use of effective treatments in typical clinical settings. To address such barriers …

Relationship Between Dysphoric Moods, Risk-Taking Behaviors, And Toxoplasma Gondii Antibody Titers In Female Veterans, Allyson Radford Duffy

USF Tampa Graduate Theses and Dissertations

The number of female veterans is increasing daily. Previous research conducted on veterans has focused primarily on males or with small samples of females. Depression and suicidality are becoming increasingly evident in returning veterans. Toxoplasma gondii is an intracellular parasite that is common in the Middle East and has been reported to cause changes in personality and behavior.

The purpose of the current study was to examine relationships between T. gondii antibody titer and socioeconomic variables, dysphoric moods, and risk-taking behaviors in a sample of 70 female veterans. Blood samples were collected and analyzed for T. gondii antibody titer and …

Accidental Detention: A Threat To The Legitimacy Of Venezuelan Democracy, Mabel Gabriela Durán-Sánchez

USF Tampa Graduate Theses and Dissertations

The main argument of this thesis is that the penitentiary crisis in Venezuela is brought about an inept criminal justice system whose functioning (or lack thereof) further exacerbates overcrowding in penitentiary facilities as well as violates the most basic human rights. More elaborately, I argue that the unintentional (mis)use of pre-trial preventive detention, one of the consequences of the inept criminal justice system, further exacerbates the overcrowding in prisons and creates serious human rights implications. The purpose of this study is to establish a connection between the penitentiary crisis in Venezuela, with a focus on pre-trial preventive detention, and the …

Social Studies Teachers In An Evaluative Role: The Peer Evaluator Experience In The Accountability Era, Martha Barnes Ford

USF Tampa Graduate Theses and Dissertations

As the evaluation of teachers becomes prominent in the current climate of educational reform, the details of teacher evaluation systems become important. The goal of the research was to gain perspective about a little-studied group key in education reform efforts to improve teacher evaluation--the peer evaluator. Teachers serving as peer evaluators were interviewed to reveal their perceived lived experiences before undertaking the role, benefits and challenges they perceived during the role, and their perception of how the experience will impact their future as educators. Extensive profiles of three peer evaluators were crafted based on in-depth interviews. The themes revealed from …

Exploring The Motives, Perceptions And Constructed Identities Of The Facilitators For One Regional Council Of A Positive Youth Development Program: Girls On The Run, Ashley Ann Gallentine

USF Tampa Graduate Theses and Dissertations

The purpose of this study is to explore the coaches' perceptions, motives and constructed identities by participating in a regional physical activity-based positive youth development program. There is growing evidence that suggests the success of positive youth development (PYD) programs depend on the environment that is created by caring adult mentors. These coaches are the delivery vehicles for these programs and play an essential role in the development of participating youth. As a result, the characteristics these coaches possess are critical to the success of the PYD implementation. Based on the application of anthropological methods and theory, this study seeks …

Unbearable Weight, Unbearable Witness: The (Im)Possibility Of Witnessing Eating Disorders In Cyberspace, Kristen Nicole Gay

USF Tampa Graduate Theses and Dissertations

This thesis argues that the recent erasure of digital pro-anorexia ("pro-ana") narratives by websites such as Tumblr, Pinterest, and Instagram represents an attempt to silence female self-starvers and reify the authority of medical associations to speak for female bodies. I draw parallels between these attempts and Gayatri Chakravorty Spivak's theory of epistemic violence, since the experiences of women are effectively discredited, through metaphors that render the thin body dangerous, to shore up professional medical authority. As an attempt to privilege the experiences of the self-starvers, I analyze one Tumblr blog with eating disorder content to listen to the letters users …
