Turning Our Darkness To Dawn: The Effect Of The Preference Clause On The Pacific Northwest Electricity Market, Willis Schueler

Theses & ETDs

This study examines the effects of the preference clause in allocating hydroelectric power. Unlike other forms of generation, much of the hydropower resources in the Pacific Northwest are owned by the federal government. Hydroelectric power also has lower costs than alternative forms of generation. The Bonneville Power Administration is federal agency charged with marketing this power. As electric demand has grown in the region, it has been forced to ration access to hydroelectric power. The BPA uses the federally mandated preference clause to determine the allocation of electricity. According to the preference clause, public utilities are given first preference to …

Redox-Regulated Relb-Ar Axis Mediates Prostate Specific Antigen Expression: Insight In Prostate Cancer Response To Radiation Therapy, Lu Miao

Theses and Dissertations--Toxicology and Cancer Biology

Although the prostate specific antigen (PSA) test is widely used in clinical settings for prostate cancer (PCa) diagnosis and post-treatment follow-up monitoring, false positive PSA test results, which contribute to over-diagnosis of PCa, and false negative results, which miss some patients with aggressive PCa, remain problems of clinical importance.

Our study demonstrates that radiation therapy, which is widely used for treatment of localized PCa, generates TNF-α in tumor cells and stromal fibroblasts, redox dependently. Interestingly, TNF-α rapidly and transiently triggers the RelA-mediated NF-κB canonical pathway, but its effect on RelB expression is more robust and long lasting, which leads to …

New Research Towards The Synthesis Of 1,4-Dibenzyl-1,4,7-Triazacyclononane-7-Monoacetate To Model Oxalate Degrading Metalloenzymes, Jaclynn Windsor

Theses & ETDs

Oxalate is a widely abundant compound found in a variety of plants, bacteria, and fungi. Oxalate is a toxic compound and excretion methods are limited in mammals because of the absence of oxalate-degrading enzymes. Accumulation of oxalate can occur via several routes, including genetic defects, dysfunctional fat absorption, excessive dietary consumption, or possibly deficiencies in metabolism of oxalate-precursors like glyoxal. Two manganese-containing metalloenzymes, oxalate oxidase (oxox) and oxalate decarboxylase (oxdc), are able to metabolize this toxic compound via an oxygen-dependent mechanism that is currently undetermined. A functional small molecule mimic of the active sites of oxox and oxdc could provide …

A Comparison Of Biological String Similarity Algorithms Application To Source Code Plagiarism Detection, Colin Wielga

Theses & ETDs

Source code plagiarism is easy to perform and difficult to catch. Detection approaches vary, with little consensus. This thesis compares several string comparison techniques borrowed from Biology on a large collection of student work containing various types of plagiarism. All the algorithms succeeded in matching a plagiarized file to its original files upwards of 90% of the time. A modification is proposed for these algorithms that drastically improves their runtimes with little or no effect on accuracy. The strengths and weaknesses of each are explored, in the hope of improving future plagiarism detection techniques.

The Impact Of The New College Of Florida Seawall Project On The Adjacent Seagrass, Cassandra Wood

Theses & ETDs

Seagrass is an important primary producer in marine ecosystems. It is under threat by many anthropogenic activities, particularly the ones that reduce water clarity and uproot living seagrass. Coastal construction, such the New College of Florida (NCF) Seawall Project conducted spring 2012 by Tandem Construction, can disturb sediment and soil, causing it to cloud the water and cover the seagrass, reducing seagrass coverage. To monitor the impact of the NCF seawall reconstruction on the nearby seagrass cover, the changing distance of the seagrass Halodule wrightii from shoreline was determined and sediment and turbidity data were collected. The restoration construction did …

Robotic Swarming Without Inter-Agent Communication, Daniel Jonathan Standish

USF Tampa Graduate Theses and Dissertations

Many physical and algorithmic swarms utilize inter-agent communication to achieve advanced swarming behaviors. These swarms are inspired by biological swarms that can be seen throughout nature and include bee swarms, ant colonies, fish schools, and bird flocks. These biological swarms do not utilize inter-agent communication like their physical and algorithmic counterparts. Instead, organisms in nature rely on a local awareness of other swarm members that facilitates proper swarm motion and behavior. This research aims to pursue an effective swarm algorithm using only line-of-sight proximity information and no inter-agent communication. It is expected that the swarm performance will be lower than …

Zero Tolerance For Marginal Populations: Examining Neoliberal Social Controls In American Schools, Brian Gregory Sellers

USF Tampa Graduate Theses and Dissertations

This study's purpose is to investigate the expansion of social control efforts in American elementary and secondary school settings, particularly the use of zero-tolerance policies. These policies entail automatic punishments, such as suspensions, expulsions, and referrals to the juvenile and criminal justice systems for a host of school-based infractions. The widespread implementation of zero-tolerance policies and the application of harsh, exclusionary sanctions have intensified over the past decade. Numerous studies have documented this rise; however, there has been little effort to explore the explanation of the expansion of school-based social controls.

A potential explanation is found in the application of …

A Life-Course Approach To Sexual Offending: Examining The Continuity Of Juvenile Sexual Offending Into Adulthood And Subsequent Patterns Of Recidivism, Maude Beaudry-Cyr

USF Tampa Graduate Theses and Dissertations

Current sex offending legislation and public opinion present an image of sexual offenders as specialized predators who are likely to exhibit continued sexually deviant behavior over the life-course. Although sex offending continuity and post-release recidivism has been independently assessed in prior research, the potential link between sex offending continuity and post-release recidivism has yet to be investigated. Using data collected on random samples of sex offenders from a Northeastern state, the present study examines the predictability of sex offender continuity and its potential linkages with general and sex recidivism, as well as identifying distinguishable risk factors related to these outcomes. …

Spatial And Temporal Patterns Of Amphibian Chytrid Fungus Batrachochytrium Dendrobatidis Occupancy In Amphibian Habitats, Tara Chestnut

Environmental Science and Management Professional Master's Project Reports

Chytrid fungi are the most ancestral of the fungi and are global in distribution. There are over 1200 species of Chytridiomycota described from freshwater, marine and terrestrial systems in temperate, tropical and tundra environments. Chytridiales are characterized by a range of morphologies and share the flask- or pot-like shape of the zoosporangia, within which motile zoospores develop. Chytrids function primarily as plant saprobes and parasites, but some also parasitize animals. Chytrids are observed in conjunction with the decline of freshwater and marine algal blooms, they decompose excess pollen, and comprise the fungal flora in gut of herbivores. Some chytrids also …

Seeds Of Resistance: Towards A Revolutionary Critical Ecopedagogy, Peter Mclaren

Education Faculty Articles and Research

The death throes of mother earth are imminent unless we decelerate the planetary ecological crisis. Critical educators, who have addressed with firm commitment topics of race, class, gender, sexuality, disability, and other social justice issues are casting their eyes to the antagonism between capitalism and nature to ask themselves how we can rationally regulate the human metabolic relation with nature. As the global power complex reduces human life and mother earth to mere production and consumption, critical revolutionary ecopedagogy is developing new, unalienated forms of selfpresence. Ecopedagogy is inspired by and inspires a new social arc, rooted in practices of …

African Americans And Reconceptualization Of Identity: Black Participation In World War I And The Rise Of The New Negro Consciousness, Farshid Nowrouzi Roshnavand, Rajabali Askarzadeh Torghabeh

Khazar Journal of Humanities and Social Sciences

Before the beginning of the twentieth century, the American Negro had undergone an allencompassing process of Otherization and inferiorization which represented blacks as inhuman, heathen and demonic. Under the tenacious hold of Calvinism, Capitalism and most notably Social Darwinism, blacks were forced to internalize the dominant negative stereotypes and thus over time came to view Uncle Tomism and assimilationism as the only possible survival strategies in the white-dominated United States. However, there emerged a paradigm shift in African Americans’ conception of themselves and their status in the country when a number of factors went hand in hand in the early …

Evolution And Expression Of The Lysozyme And Beta1,4-Galactosyltransferase Families In Mammals : Possible Roles In Fertilization, Jason Michael Biegel

Legacy Theses & Dissertations (2009 - 2024)

Understanding the specificity of sperm-egg recognition during mammalian fertilization has been a topic of intense study for many years, and yet the biochemical basis for this process is still largely unknown. Mammalian eggs are covered by thick glycoprotein coats, called zona pellucida (ZP), which contain glycans of varying structures that must be specifically recognized, and presumably cleaved, for fertilization to occur. Various experiments have implicated B1,4-galactosyltransferase 1 (B4GalT1) in the ability of mouse sperm to bind the ZP. Here I present evidence that additional members of the B4GalT family (specifically B4GalT3 and B4GalT4) are present on mouse and rat sperm, …

However, the long term behavioral implications of preterm birth are still being investigated. The current study sought to explore the relationships between birth status (preterm or full term), temperament, and psychopathology. A sample of preterm children and their parents, as well as a sample of age-matched controls and their parents, were recruited for participation in this study. The former group was recruited for participation through a local hospital while the latter group was recruited through flyer distributions in several local school districts. …

The Genetic Engineering Of Motor Proteins, Rachael M. Hartz

Legacy Theses & Dissertations (2009 - 2024)

Molecular motors are a remarkable feature within living organisms that are responsible for directional mechanical motion, which is driven by adenosine triphosphate (ATP) hydrolysis. Actin-binding molecular motors are of specific interest in the field of nanotechnology as filamentous actin is capable of carrying cargo, such as quantum dots, while it is translocated along a motor coated surface. The binding regions of motor proteins, which are known to interact with actin, such as Myosin, have been thoroughly examined and identified. Rapid genetic engineering of the ATP-hydrolyzing enzyme, adenosine kinase, to incorporate these binding regions is possible through the use of site- …

The current study evaluated the risks of following a weight management program for healthy young adults who served as staff members in immersion treatment of obesity over the course of a summer. Participants included Wellspring staff members (n = 108) along with a comparison group of young adults with similar …

Exploring The Impact Of Behaviorally Enacted Vs. Imaginal Delivery Of An Acceptance-Based Metaphor On Acute Panicogenic Distress In Acceptance And Commitment Therapy : A Comparative Evaluation, Kristin N. Herzberg

Legacy Theses & Dissertations (2009 - 2024)

Metaphors, or indirect and less literal forms of communication in the therapeutic setting, can be powerful and clinically impactful components of psychosocial interventions. Metaphors are widely used in therapeutic practice, and rest at the core of newer third generation behavior therapies such as Acceptance and Commitment Therapy (ACT; Hayes, Strosahl & Wilson, 2011). Yet, to date, systematic empirical evaluations of the effectiveness of metaphor in the treatment of anxiety disorders and other forms of psychopathology have been largely ignored. Thus, the present study aimed to evaluate the impact of an ACT-relevant metaphor on acute panicogenic distress (i.e., panic-like symptoms). Specifically, …

The Role Of Adaptation To Disability And Disease In Public Health, Meghan Mary Connors

Legacy Theses & Dissertations (2009 - 2024)

Some patients with chronic disabilities and diseases are able to adapt to their health states and, as a result, rate their quality of life higher than hypothetical patients imagining themselves to be in such states. Due to this phenomenon of adaptation, there is much controversy surrounding the effect of adaptation on patient preferences and the role that these adapted preferences ought to play in health care resource allocation decisions. The process of adaptation affects public health debates about whether we ought to give priority to the worst off in allocation decisions because within traditional public health frameworks, it is unclear …

Neutralizing Antibodies Against The Ricin Toxin Binding Subunit (Rtb), Anastasiya Yermakova

Legacy Theses & Dissertations (2009 - 2024)

Ricin is a toxin that is naturally produced by the seeds of the castor bean plant Ricinus communis, and is part of a family of A-B toxins that includes Shiga, cholera, and anthrax toxins. The toxin consists of two subunits, RTA and RTB, which are linked by a disulfide bond. RTA is an RNA N-glycosidase that selectively targets and inactivates 28S ribosomal RNA, thereby arresting protein synthesis and leading to cell death. RTB is a galactose/ N-acetylgalactosamine-specific lectin that mediates attachment, entry, and intracellular trafficking of ricin in host cells. Currently, there is no approved vaccine or therapeutics available against …
