The Development Of A "Genetic Eyewitness" Profiling System For Low Template Forensic Specimens: Identification Of Novel Protein, Rna, And Dna Biomarkers, Erin Hanson

Electronic Theses and Dissertations

In many criminal investigations, valuable information regarding the physical appearance of suspected perpetrators or the time and order of events that transpired are provided by eyewitness accounts. However, the information obtained from eyewitnesses is often constrained by human recollection or subjective accounts and provides a biased description of the perpetrator's appearance or an inaccurate time line of events. Additionally, in numerous situations eyewitness accounts may not be available. An increasing reliance therefore is placed on the biological evidence recovered during criminal investigations to act as a silent witness, providing unbiased and scientific information that may aid in the resolution of …

Technological Disasters: An Investigation Of The Conservation Of Resources Theory On Depression, Brian Gentry Jan 2008

Technological Disasters: An Investigation Of The Conservation Of Resources Theory On Depression, Brian Gentry

Electronic Theses and Dissertations

Researchers studying the affects of resource loss following a technological disaster have exclusively investigated the acute period directly after the event occurred. This study applied Hobfoll's (1988, 1989) Conservation of Resources model in order to examine the long term effects of resource loss on depression in Cordova, Alaska a decade after the Exxon Valdez Oil spill. Results suggest that resource loss was a more prominent predictor for depression than demographics, involvement in the on-going litigation, or commercial fishing jobs. The research concludes that certain aspects of resource loss are critical in the development of depression after a technological disaster, and …

Prevalence And Severity Of Fibropapillomatosis In Juvenile Green Turtles (Chelonia Mydas) In Three Habitats On Florida's Eas, Kelly Borrowman Jan 2008

Prevalence And Severity Of Fibropapillomatosis In Juvenile Green Turtles (Chelonia Mydas) In Three Habitats On Florida's Eas, Kelly Borrowman

Electronic Theses and Dissertations

Fibropapillomatosis (FP) is a tumor-forming disease mainly found in juvenile green turtles (Chelonia mydas) inhabiting Florida's east coast. Despite increased research on the herpes virus that putatively causes it, long-term assessment is still needed of the distribution and severity of FP. Using the decades-long database compiled by the University of Central Florida Marine Turtle Research Group, I determined FP severity and distribution at three different sites: Indian River Lagoon (IRL), Sabellariid Worm Reef (SWR) and Trident Submarine Basin (TSB). Fibropapillomatosis occurred in > 50% of IRL turtles, 18% of SWR turtles and <1% of TSB turtles. Regression of FP tumors was correlated with its prevalence, i.e. when and where FP was common, tumor regression was common. The probability of a turtle being non-afflicted or mildly afflicted increased with both increasing straight-line carapace length (SCL) and increasing relative body condition (residuals of log body mass versus log SCL). Mean annual growth rates of IRL and SWR turtles did not vary with FP severity; however, mean annual growth rates in IRL (1.10 cm/y) were significantly higher than in SWR (1.05 cm/y) and TSB (1.04 cm/y). Annual apparent survival estimates for IRL and TSB turtles were 0.72 and 0.73, respectively, and were constant over time. Even with increased prevalence of FP, annual apparent survival estimates were constant and similar to survival estimates of juvenile green turtles in areas without FP. In IRL, survival rates among FP Categories 0, 1 and 2 were similar (0.74, 0.74 and 0.81 respectively) and lower only for FP Category 3 (0.63). Thus, while FP occurred in > 50% of turtles in some Florida east coast populations, …

Control Of Stomatal Formation In Arabidopsis Thaliana Inflorescence Stem, Nalini Odapalli Jan 2008

Control Of Stomatal Formation In Arabidopsis Thaliana Inflorescence Stem, Nalini Odapalli

Electronic Theses and Dissertations

Stomata are cellular structures that control water loss and gas exchange through the plant epidermis. Stomata arise from special stem cells called meristemoids through a series of programmed asymmetric divisions that are controlled by cell signaling, or via multitude of regulatory pathways and intercellular communication between epidermal cells. In Arabidopsis thaliana, stomata are spaced non-randomly in the epidermis by cell-cell signaling of the receptor-like protein TOO MANY MOUTHS (TMM) as well as other proteins. Point mutation of the TMM gene prevents the development of stomata in some tissues like inflorescence stems. Investigation of tmm mutant stems showed that self-renewing stem …

Social Grouping Behaviors Of Captive Female Hippopotamus Amphibius, Tracy Blowers Jan 2008

Social Grouping Behaviors Of Captive Female Hippopotamus Amphibius, Tracy Blowers

Electronic Theses and Dissertations

Levels of sociality vary depending on the costs and benefits associated with grouping behavior. Grouping species form either ephemeral aggregations due to resource availability, or structured groups based on familiarity of individuals. Because there are different costs and benefits associated with different types of groups, it is important to understand more about group structure before making predictions about specific behaviors. Female Hippopotamus amphibius are known to aggregate in the wild but the true nature of their grouping behavior is still not understood. My objective was to determine if captive female hippos form either ephemeral aggregations or social groups. Behavioral data, …

The Endocytic Protein Numb Regulates App Metabolism And Notch Signaling: Implications For Alzheimer's Disease, George Kyriazis Jan 2008

The Endocytic Protein Numb Regulates App Metabolism And Notch Signaling: Implications For Alzheimer's Disease, George Kyriazis

Electronic Theses and Dissertations

Increased production of amyloid beta (A-beta) peptide, via altered proteolytic cleavage of amyloid protein precursor (APP), and abnormalities in neuronal calcium homeostasis play central roles in the pathogenesis of Alzheimer's disease (AD). Notch1, a membrane receptor that controls cell fate decisions during development of the nervous system, has been linked to AD because it is a substrate for the gamma-secretase protein complex in which mutations cause early-onset inherited AD. Numb is an evolutionarily conserved endocytic adapter involved in the internalization of transmembrane receptors. Mammals produce four Numb isoforms that differ in two functional domains, a phosphotyrosine-binding domain (PTB) and a …

Trait Arousability And Its Impact On Adaptive Multimedia Training, Sae Schatz Jan 2008

Trait Arousability And Its Impact On Adaptive Multimedia Training, Sae Schatz

Electronic Theses and Dissertations

Today's best intelligent, adaptive, multimedia trainers have shown excellent performance; however, their results still fall far-short of what good human tutors can achieve. The overarching thesis of this paper is that future intelligent, adaptive systems will be improved by taking into account relevant, consistent, and meaningful individual differences. Specifically, responding to individual differences among trainees will (a) form more accurate individual baselines within a training system, and (b) better inform system responses (so that they interpret and respond to observable data more appropriately). One variable to consider is trait arousability, which describes individual differences in sensitivity to stimuli. Individuals' arousability …

Resiliency Factors And Pathways To Incarceration In Female Survivors Of Childhood Sexual Abuse, Kia Asberg Jan 2008

Resiliency Factors And Pathways To Incarceration In Female Survivors Of Childhood Sexual Abuse, Kia Asberg

Electronic Theses and Dissertations

Studies find consistently that survivors of childhood sexual abuse (CSA) are likely to suffer from depression, post-traumatic stress, and problematic substance use, and may experience also a variety of adjustment difficulties in several emotional, behavioral, and interpersonal domains. Involvement with the legal system is one such outcome to consider, especially given the increasing number of women serving time in correctional facilities with nearly two-thirds of these women being survivors of CSA (e.g., Browne, Miller, & Maguin, 1999). The current literature lacks comparisons between female survivors of CSA who have legal involvement and those who do not; hence, the current study …
