The "White-Eyed" Eastern Towhee: A Molecular Assessment Of The Validity Of Pipilo Erythrophthalmus Alleni, Jeremy Shawn Batten

UNLV Retrospective Theses & Dissertations

Exploring the factors that influence the distribution and diversification of organisms is essential to the field of evolutionary biology. Molecular examination across a species' distribution may result in the discovery of differentiated populations that, when interpreted in the context of past events (e.g. climate change), may elucidate the causal mechanisms. Comparative phylogeographic studies have revealed both similar and disparate genetic patterns among co-distributed organisms, although similar geographic patterns may differ greatly in temporal scale and thus in the magnitude of genetic differentiation. Studies of diverse taxa occurring across the southeastern United States have revealed several common patterns of intraspecific divergence …

Exploratory Study Of Construction Safety Culture Through Systems Thinking, Charles J. Jr Benford Jan 2008

Exploratory Study Of Construction Safety Culture Through Systems Thinking, Charles J. Jr Benford

UNLV Retrospective Theses & Dissertations

Since its conception, in 1986 after the Chernobyl accident, the term "safety culture" has gained major popularity throughout many systems, especially the construction industry. Although this concept has gained much popularity over the course of two decades, it remains a heavily debated topic between advocates and skeptics for various reasons. Much of the skepticism is due to the failure of proponents of the concept to clearly define and provide an understanding of those factors that comprise what "safety culture" is, and how it can be achieved. A system (particularly a construction system) that possesses a safety culture is one in …

Sex And The Agricultural Transition: Dental Health Among Early Agricultural Females, Misty Fields Jan 2008

Sex And The Agricultural Transition: Dental Health Among Early Agricultural Females, Misty Fields

UNLV Retrospective Theses & Dissertations

This project analyzed dentition from a sample (n =142) of Early Agricultural period skeletons (B.C. 1600-200 A.D.) from the site of La Playa (SON F:10:3), Sonora, Mexico. Data was collected on pathology rates for dental caries and antemortem tooth loss (AMTL) to test the hypothesis that hormone-fluctuations associated with pregnancy increase dental pathology in females. Males and females were not found to have significant differences in caries rates. However, statistically significant differences in AMTL were found with females exhibiting more tooth loss than males ( p=.022). When compared across age categories, reproductive-age females had substantial increases in AMTL compared to …

The Three Saras, Peter Golub Jan 2008

The Three Saras, Peter Golub

UNLV Retrospective Theses & Dissertations

There are two important foundations upon which my poetry stands: (1) Epistemologically I am an empiricist, not a realist; (2) my poetry is not empirical. That is, it operates in the realm of the thought experiment --the laboratory of the mind. This demon is a good analogy to how I write poetry. I usually get the urge to write a poem after thinking about a question, or a fact. In Maxwell's gedankenexperiment the fact is the second law of thermodynamics, and the question is: What if a demon partitioned the fast and slow molecules in a box?;Hence, there is this …

Energetics Of Insect Metamorphosis, Allison Brighton Merkey Jan 2008

Energetics Of Insect Metamorphosis, Allison Brighton Merkey

UNLV Retrospective Theses & Dissertations

During metamorphosis, Drosophila melanogaster pupae undergo a transformation which rearranges almost all larval tissues into an adult fly. During this time, it is surprising that pupae exhibit a U-shaped curve for metabolic rate, where metabolism decreases dramatically after pupariation and increases shortly before eclosion. Using temperature to offset the cost of development during metamorphosis, I demonstrate that the total energy cost for metamorphosis depends on temperature and associated differences in developmental time. Pupae tended to consume more triglycerides over the course of development at low and high temperatures. Changes in oxygen level did not affect the U-shaped curve of carbon …

Diversity, Biogeography, And Geochemical Habitat Of Korarchaeota In Continental Hot Springs, Robin Lea Miller Jan 2008

Diversity, Biogeography, And Geochemical Habitat Of Korarchaeota In Continental Hot Springs, Robin Lea Miller

UNLV Retrospective Theses & Dissertations

Microorganisms have traditionally been characterized based on their morphology and physiology. However, this formula does not account for the importance of a microorganism's habitat, which is intimately linked to its physiology. The Korarchaeota comprise a deeply branching archaeal lineage that has proven to be difficult to isolate and, consequently, has remained uncharacterized until recently. The aim of this study was to evaluate the physicochemical and biogeographical distribution of Korarchaeota in hot springs of the Great Basin and Yellowstone National Park. Ninety-nine sediment samples were collected from hot springs with temperatures ranging from 40.7-94.3°C and pH ranging from 1.3-9.2, while recording …

Passive Integrated Transponders In Gila Elegans: Location, Retention, Stress, And Mortality, Andrea Dee Montony

UNLV Retrospective Theses & Dissertations

Despite large-scale propagation and rearing efforts few of the critically endangered bonytail, Gila elegans, are recovered following release from hatcheries. This study tested the role of passive integrative transponder (PIT) tag loss and tagging associated stress and mortality in these low recoveries. Bonytail exhibited 98-100 percent tag retention regardless of insertion direction (ventral toward anterior and anterior toward ventral). Plasma cortisol levels were measured at 0, 0.5, 3, 6, 12, and 24 hours following PIT-tagging in fish held at three temperatures (12, 16, and 20°C) as an indicator of stress. Bonytail tagged at 16°C had significantly lower plasma cortisol levels …

This History Of Small Things, Paul Sacksteder Jan 2008

This History Of Small Things, Paul Sacksteder

UNLV Retrospective Theses & Dissertations

The poems in this thesis seek to explore the notion of uncertainty in terms of its value as both an intellectual and political position. Uncertainty is echoed both in subject matter and form. It serves not as a tool of conservatism, but as an opportunity towards empathy and expansion in a narrowing world; Ecology also plays a prominent role in both the poetry as well as the development of uncertainty and sustainability. The poems seek to broaden conceptions of ecology by drawing often disparate objects and concepts in proximity. These poems then exist in the anxiety of trying to understand …

Selective Disruption Of Hte Blood-Brain Barrier By Photochemical Internalization, Michelle Jie Zhang Jan 2008

Selective Disruption Of Hte Blood-Brain Barrier By Photochemical Internalization, Michelle Jie Zhang

UNLV Retrospective Theses & Dissertations

Failure to eradicate infiltrating glioma cells using conventional treatment regimens results in tumor recurrence and is responsible for the dismal prognosis of patients with glioblastoma multiforme (GBM). This is due to the fact that migrating glioma cells are protected by the blood-brain barrier (BBB) which prevents the delivery of most anti-cancer agents. The overall objective of this work was to evaluate the ability of photochemical internalization (PCI) to selectively disrupt the BBB in rats. This will permit access of anti-cancer drugs to effectively target infiltrating tumor cells, and potentially improve the treatment effectiveness for malignant gliomas; PCI treatment, coupling the …

The Relationship Between Gestational Pcb Exposure, Thyroid Hormones And Adhd, Vicki M Tripoli Jan 2008

The Relationship Between Gestational Pcb Exposure, Thyroid Hormones And Adhd, Vicki M Tripoli

UNLV Retrospective Theses & Dissertations

PCB exposure has been associated with a reduction in circulating thyroid hormones via several different mechanisms. While thyroid hormones can influence many physiological endpoints in adults, precise concentrations during critical periods of gestation are crucial to normal development. Maternal consumption of PCB contaminated fish has been associated with developmental problems in animals and humans. Alterations of thyroid hormones is postulated to be one possible source of the developmental latencies associated with PCB exposure. Thus, this study investigated the influence of maternal thyroxine supplements in rodents exposed to a low dose of commercial PCBs; Pregnant Long-Evans rats were exposed to one …
