Genetic Structure And Demographic Analysis Of Key Deer (Odocoileus Virginianus Clavium), Vicki Villanova

Electronic Theses and Dissertations

Recent improvements in genetic analyses have paved the way in using molecular data to answer questions regarding evolutionary history, genetic structure, and demography. Key deer are a federally endangered subspecies assumed to be genetically unique (based on one allozyme study), homogeneous, and have a female-biased population of approximately 900 deer. I used 985bp of the mitochondrial cytochrome b gene and 12 microsatellite loci to test two hypotheses: 1) if the Moser Channel is a barrier to gene flow, I should expect that Key deer are differentiated and have reduced diversity compared to mainland deer and (2) if isolation on islands …

Instant Conductors, Mary Petralia

Electronic Theses and Dissertations

Instant Conductors is a collection of poems meant to engage the reader in conversation about the imperfect nature of the world in relation to the imperfect nature of readerly experience. Walt Whitman wrote, “I have instant conductors all over me whether I pass or stop / they seize every object and lead it harmlessly through me.” And so the things on these pages are intent on transmitting what one experiences in the minutiae of memory and routine: the sounds that surround a blackwater tidepool, what one imagines happens behind the closed doors of the friendly neighbors, or what's heard in …

The Effect Of Precipitation On The Spread Of Mosquito-Borne Diseases: A Case Study Of Florida Counties, Marvin Osbourne

Electronic Theses and Dissertations

The state of Florida is the third most populous state in the United States of America, with six (6) of its metropolitan areas dubbed as the fastest growing in the entire country. A mosquito bite may mean the transmission of a virus or disease which might be fatal. Hence, there is a need for the state to control mosquitoes through the various Departments of Mosquito Control in each of its sixty-seven (67) counties. Six locally acquired mosquito-borne viruses which affect humans and animals in the state of Florida were considered. This thesis used statistical methods to examine data for rainfall, …

Electronic Theses and Dissertations

This study was focused on the effect of pre-service teaching utilizing a co-teaching model on student achievement at an elementary school in a large, urban school district in central Florida. The contribution of university student teachers (i.e., interns) to elementary school achievement was investigated. Specifically explored was the difference between student achievement scores in classes with interns who participated in a co-teaching model and interns in classes that did not employ any structured approach to intern teaching. The researcher compared seven classes that employed co-teaching, where the university intern teacher and master teacher remained in the class conducting instruction, to …

Diabetes Phenotypes In Transgenic Pancreatic Cancer Mouse Models, Toya Albury-Warren

Electronic Theses and Dissertations

Protein Kinase B/AKT, a serine/threonine kinase with three isoforms (AKT1-3), is downstream of phosphatidylinositol 3-kinase (PI3K), and signals through the phosphorylation and subsequent activation or inhibition of downstream substrates, such as mammalian target of rapamycin complex 1 (mTORC1) or glycogen synthase kinase 3 beta (GSK-3?), respectively. The AKT1 isoform is predominantly recognized for regulation of cell survival, growth, and proliferation, due to its constitutive activation in pancreatic cancers (e.g., islet cell carcinoma and pancreatic adenocarcinoma). The progression of pancreatic ductal adenocarcinoma (PDAC), the most lethal common cancer, is initiated by activation mutations of the KRas oncogene. This leads to additional …

Inverse-Consistent Determination Of Young's Modulus Of Human Lung, Behnaz Seyfi Noferest

Electronic Theses and Dissertations

Human lung undergoes respiration-induced deformation due to sequential inhalation and exhalation. Accurate determination of lung deformation is crucial for tumor localization and targeted radiotherapy in patients with lung cancer. Numerical modeling of human lung dynamics based on underlying physics and physiology enables simulation and virtual visualization of lung deformation. Dynamical modeling is numerically complicated by the lack of information on lung elastic behavior, structural heterogeneity as well as boundary constrains. This study integrates physics-based modeling and image-based data acquisition to develop the patient-specific biomechanical model and consequently establish the first consistent Young's modulus (YM) of human lung. This dissertation has …

The Effect Of Landscape Variables On Adult Mosquito (Diptera:Culicidae)Diversity And Behavior, Caitlyn Debevec

Electronic Theses and Dissertations

Diseases vectored by mosquitoes cause millions of deaths each year. In modern times Florida*s disease risk has been reduced due to efforts to lessen the prevalence of mosquitoes through habitat modification of non-adults. With emerging diseases (i.e. Dengue and Chikunguya) encroaching into Florida from the Caribbean, this traditional approach may not be enough. Alternatively, we can better understand the ecology of how disease works in an ecosystem. One possible way is through the Dilution Effect, which states that the more species that are in a system the lower the chance for zoonosis. This project models mosquito diversity across regions, land …

Towards Closed-Loop Deep Brain Stimulation: Behavior Recognition From Human Stn, Soroush Niketeghad

Electronic Theses and Dissertations

Deep brain stimulation (DBS) provides significant therapeutic benefit for movement disorders such as Parkinson’s disease (PD). Current DBS devices lack real-time feedback (thus are open loop) and stimulation parameters are adjusted during scheduled visits with a clinician. A closed-loop DBS system may reduce power consumption and side effects by adjusting stimulation parameters based on patient’s behavior. Thus behavior detection is a major step in designing such systems. Various physiological signals can be used to recognize the behaviors. Subthalamic Nucleus (STN) Local field Potential (LFP) is a great candidate signal for the neural feedback, because it can be recorded from the …

Examining Multiple Approaches For The Transferability Of Safety Performance Functions, Ahmed Tarek Ahmed Farid

Electronic Theses and Dissertations

Safety performance functions (SPFs) are essential in road safety since they are used to predict crash frequencies. They are commonly applied for detecting hot spots in network screening and assessing whether road safety countermeasures are effective. In the Highway Safety Manual (HSM), SPFs are provided for several crash classifications for several types of roadway facilities. The SPFs of the HSM are developed using data from multiple states. In regions where jurisdiction specific SPFs are not available, it is custom to adopt nationwide SPFs for crash predictions then apply a calibration factor. Yet, the research is limited regarding the application of …

Optimization Of Glycerol And Biodiesel Waste Prefermentation To Improve Ebpr, Marzieh Ghasemi

Electronic Theses and Dissertations

The enhanced biological phosphorus removal (EBPR) process efficiency relies on different operational and process conditions especially the type of carbon source available in the wastewater. Acetic acid and propionic acid are the two major volatile fatty acids (VFAs) found in domestic wastewater which can drive biological phosphorus (P) removal to the desired level. However, often domestic wastewater does not have a sufficient amount of VFAs. Due to high acetate and propionate production-cost, it is not economic to add acetate and propionate directly in full-scale wastewater treatment plants. This brought up the idea of using external carbon sources (e. g. molasses …

A Generic Framework For Multi-Method Modeling And Simulation Of Complex Systems Using Discrete Event, System Dynamics And Agent Based Approaches., Konstantinos Mykoniatis

Electronic Theses and Dissertations

Decisions about Modeling and Simulation (M&S) of Complex Systems (CS) need to be evaluated prior to implementation. Discrete Event (DE), System Dynamics (SD), and Agent Based (AB) are three different M&S approaches widely applied to enhance decision-making of complex systems. However, single type M&S approaches can face serious challenges in representing the overall multidimensional nature of CS and may result in the design of oversimplified models excluding important factors. Conceptual frameworks are necessary to offer useful guidance for combining and/or integrating different M&S approaches. Although several hybrid M&S frameworks have been described and are currently deployed, there is limited guidance …

Oral iron salts or colloidal parenteral iron formulations are treatment options for iron replenishment since several decades, but they are associated with severe side effects along with other patient noncompliance issues. Transdermal delivery of iron could be a potential alternative to …

Mississippi Asl Project, James Corey Blount

Electronic Theses and Dissertations

American Sign Language (ASL) is a manual language used by many deaf people in the United States and Canada. For much of its existence, ASL was believed to be a system of rudimentary gestures and signs based on the English language. However, studies that analyzed the linguistic properties of this signed ‘mode’ (Stokoe, 1960) legitimized that it was a language independent of spoken language, with its own system of principles and elements to construct meaningful utterances. Like any language, ASL is influenced by the social demographics of its users. Social demographics such as ethnicity, geographic location, age, gender, and socioeconomic …

Mass Media And The Evolution Of The Environmental Movement: 1960-1979, Donald Anguish

Electronic Theses and Dissertations

This thesis examines how particular forms of mass media spurred and guided the United States environmental movement of the 1960s and 1970s. Its objective is to better understand how mass media contributed to the evolution of the environmental movement. Three particular types of media form the basis of this study: writing (books, newspapers, and magazines), audio-visual material (movies and television), and photographs. These three mediums of communications and their intrinsic effects on the human psyche and society as a whole are major contributing factors to a raised environmental consciousness, a lasting legacy of environmentalism, and the promotion of the environmental …

Recursive Behavior Recording: Complex Motor Stereotypies And Anatomical Behavior Descriptions, Nathaniel Bobbitt

Electronic Theses and Dissertations

A novel anatomical behavioral descriptive taxonomy improves motion capture in complex motor stereotypies (CMS) by indexing precise time data without degradation in the complexity of whole body movement in CMS. The absence of etiological explanation of complex motor stereotypies warrants the aggregation of a core CMS dataset to compare regulation of repetitive behaviors in the time domain. A set of visual formalisms trap configurations of behavioral markers (lateralized movements) for behavioral phenotype discovery as paired transitions (from, to) and asymmetries within repetitive restrictive behaviors. This translational project integrates NIH MeSH (medical subject headings) taxonomy with direct biological interface (wearable sensors …

The Diverse Nature Of Corporal Punishment: An Investigation Of The Relationship Between Students’ Perceptions Of The Discipline Method, Academic Performance, And Social Behaviors, Demeka Lashun Smith

Electronic Theses and Dissertations

The use of corporal punishment has been debated due to linkage to decreased academic performance (Hickmon, 2010) and negative social behaviors (Hicks-Pass, 2009). Disparities exist in who has received corporal punishment (Rollins, 2012). Although there is much research pertaining to corporal punishment, there have been few studies conducted where students' opinions of it have been obtained (Holden, 2002). Thus, there is a need to examine students' perceptions of corporal punishment. The purpose of this study is to determine the relationship between academic performance, social behaviors, and previous experience with corporal punishment at school and perceptions of corporal punishment among elementary …

Evaluation Of Inhibitors Of Histone Deacetylases As Potential Neurotrophic Agents, Surabhi Shukla

Electronic Theses and Dissertations

The inhibitors of histone deacetylases (HDACs) have shown promising neuroprotective and neuroactive properties. A set of pan- and isoform-specific HDAC inhibitors were evaluated for neurotrophic activity on Neuroscreen-1 (NS-1) cells, a subclone of PC-12 (rat pheochromocytoma) cells.

The HDAC inhibitors were tested alone and in combination with nerve growth factor (NGF). An in vitro method has been standardized that measures neurite outgrowth along with cytotoxicity of test compounds in a single assay. The neurotrophin signaling pathways were interrogated with selective inhibitors of MEK1/2 (PD98059/U0126) PI3K (LY294002) and TrkA (GW441756) and phosphorylation of target kinases. Associated factors namely, acetylation of histones …

Oviposition Site Selection By Mosquitoes: Predator-Released Kairomones And Responses To Different Taxa, Lauren Larea Eveland

Electronic Theses and Dissertations

Oviposition site selection is a critical reproductive behavior for egg-laying organisms that offer little to no parental care. Determining the mechanisms females use to assess sites is critical to understanding life history traits, community structure, and species interactions. Mosquitoes are excellent model organisms for studying oviposition site selection for numerous reasons: 1) a poor decision can lead to zero reproductive success, 2) females actively assess and choose among habitat patches when locating an oviposition site, 3) larvae remain in the habitat where they hatch until they metamorphose, and 4) they lay conspicuous egg rafts that allow direct assessment of oviposition. …
