Fetal-Pelvic Disproportion And Pelvic Asymmetry As A Potential Cause For High Maternal Mortality In Archaeological Populations, Sarah Stansfield Jan 2013

Fetal-Pelvic Disproportion And Pelvic Asymmetry As A Potential Cause For High Maternal Mortality In Archaeological Populations, Sarah Stansfield

Electronic Theses and Dissertations

Females of childbearing age are overrepresented in the population of the Kellis 2 cemetery (100-450 AD) in the Dakhleh Oasis, Egypt (Wheeler 2009). The demographic overrepresentation found here may be the result of complications related to childbirth. Clinical literature demonstrates that fetal size is rarely an explanation for failed labor (Cunningham et al. 2001) and the fetuses buried in the Kellis 2 Cemetery at the Dakhleh Oasis were not larger than average (Tocheri et al. 2005), directing the focus to dimensions of the maternal pelvis for evidence of obstetrical issues, such as abnormally compressed pelvises. To formulate a test for …

Investigation Of A Novel Magnesium And Acidified Ethanol System For The Degradation Of Persistent Organic Pollutants, Phillip Maloney Jan 2013

Investigation Of A Novel Magnesium And Acidified Ethanol System For The Degradation Of Persistent Organic Pollutants, Phillip Maloney

Electronic Theses and Dissertations

For centuries chemists have sought to improve humankind’s quality of life and address many of society’s most pressing needs through the development of chemical processes and synthesis of new compounds, often with phenomenal results. Unfortunately, there also are many examples where these chemicals have had unintended, detrimental consequences that are not apparent until years or decades after their initial use. There are numerous halogenated molecules in this category that are globally dispersed, resistant to natural degradation processes, bioaccumulative, and toxic to living organisms. Chemicals such as these are classified as persistent organic pollutants (POPs), and due to their negative environmental …

Cerium Oxide Nanoparticles Sensitize Pancreatic Cancer Cells To Radiation By Promoting Acidic Ph, Ros, And Jnk Dependent Apoptosis, Melissa Wason Jan 2013

Cerium Oxide Nanoparticles Sensitize Pancreatic Cancer Cells To Radiation By Promoting Acidic Ph, Ros, And Jnk Dependent Apoptosis, Melissa Wason

Electronic Theses and Dissertations

Side effects of radiation therapy (RT) remain the most challenging issue for pancreatic cancer treatment. In this report we determined whether and how cerium oxide nanoparticles (CONPs) sensitize pancreatic cancer cells to RT. CONP pretreatment enhanced radiation-induced reactive oxygen species (ROS) production preferentially in acidic cell-free solutions as well as acidic human pancreatic cancer cells. In acidic environments, CONPs favor the scavenging of superoxide radical over the hydroxyl peroxide resulting in accumulation of the latter whereas in neutral pH CONPs scavenge both. CONP treatment prior to RT markedly potentiated the cancer cell apoptosis both in culture and in tumors and …

Wetland Diversity In A Disturbance-Maintained Landscape: Effects Of Fire And A Fire Surrogate On Aquatic Amphibian Survival And Species Depauperateness., Joyce Klaus Jan 2013

Wetland Diversity In A Disturbance-Maintained Landscape: Effects Of Fire And A Fire Surrogate On Aquatic Amphibian Survival And Species Depauperateness., Joyce Klaus

Electronic Theses and Dissertations

Disturbance is one of the central concepts explaining how diversity arises and is perpetuated in ecological time. A good model system for testing hypotheses related to disturbance is the longleaf pine ecosystem in the southeastern U.S. because in this ecosystem frequent, low-severity fires acts as a disturbance that maintains a unique vegetation structure and high species richness. Vegetation structure influences animal distributions; in fire-dependent ecosystems many animals rely on open-structured, fire-maintained vegetation but shrubs and trees encroach into fire-dependent ecosystems where fire has been excluded. Prescribed burning and mechanical removal are commonly used as restoration tools to control encroachment. To …

Inverse Problems In Multiple Light Scattering, John Broky Jan 2013

Inverse Problems In Multiple Light Scattering, John Broky

Electronic Theses and Dissertations

The interaction between coherent waves and material systems with complex optical properties is a complicated, deterministic process. Light that scatters from such media gives rise to random fields with intricate properties. It is common perception that the randomness of these complex fields is undesired and therefore is to be removed, usually through a process of ensemble averaging. However, random fields emerging from light matter interaction contain information about the properties of the medium and a thorough analysis of the scattered light allows solving specific inverse problems. Traditional attempts to solve these kinds of inverse problems tend to rely on statistical …

An Event-Related Potential Investigation Of Error Monitoring In Adults With A History Of Psychosis, Chi Chan Jan 2013

An Event-Related Potential Investigation Of Error Monitoring In Adults With A History Of Psychosis, Chi Chan

Electronic Theses and Dissertations

Metacognition, which involves monitoring and controlling of one’s thoughts and actions, is essential for guiding behavior and organization of information. Deficits in self-monitoring have been suggested to lead to psychosis and poor functional outcome. Abnormalities in eventrelated potentials originating from the anterior cingulate cortex (ACC), a brain region associated with error detection, have been consistently reported in individuals with schizophrenia during error monitoring tasks. This study sought to examine whether these abnormalities are present in individuals with a history of psychosis across diagnostic categories and whether they are associated with subjective appraisal of self-performance and personality traits related to psychosis. …

Solid Phase Extraction Room Temperature Fluorescence Spectroscopy For The Direct Quantification Of Monohydroxy Metabolites Of Polycyclic Aromatic Hydrocarbons In Urine Samples, Korina Jesusa Calimag Jan 2013

Solid Phase Extraction Room Temperature Fluorescence Spectroscopy For The Direct Quantification Of Monohydroxy Metabolites Of Polycyclic Aromatic Hydrocarbons In Urine Samples, Korina Jesusa Calimag

Electronic Theses and Dissertations

Polycyclic aromatic hydrocarbons (PAH) are important environmental pollutants generally formed during incomplete combustion of organic matter containing carbon and hydrogen. Introduced into the human body by adsorption through the skin, ingestion or inhalation, the biotransformation processes of PAH lead to the formation of multiple metabolites. Due to the short elimination lifetime from the body, the quantitative determination of monohydroxy-PAH (OH-PAH) in urine samples provides accurate information on recent exposure to environmental PAH. Urine analysis of OH-PAH with established methodology relies on sample clean-up and pre-concentration followed by chromatographic separation and quantification. Although chromatographic techniques provide reliable results in the analysis …

Remediation Of Polychlorinated Biphenyl (Pcb) Contaminated Building Materials Using Non-Metal And Activated Metal Treatment Systems, Tamra Legron-Rodriguez

Electronic Theses and Dissertations

PCBs are recalcitrant compounds of no known natural origin that persist in the environment despite their ban by the United States Environmental Protection Agency in 1979 due to negative health effects. Transport of PCBs from elastic sealants into concrete, brick, and granite structures has resulted in the need for a technology capable of removing these PCBs from the materials. This research investigated the use of a nonmetal treatment system (NMTS) and an activated metal treatment system (AMTS) for the remediation and degradation of PCBs from concrete, brick, and granite affixed with PCB-laden caulking. The adsorption of PCBs onto the components …

Capillarity: A Theory Of Mlearning And Its Application In Emerging Markets, David Rogers Jan 2013

Capillarity: A Theory Of Mlearning And Its Application In Emerging Markets, David Rogers

Electronic Theses and Dissertations

The theory of capillarity is an organic metaphor invoked to explore the role of network communications as a vehicle for education in a healthy society. Capillarity is offered as a theory in two parts: a mechanism for distribution and a method for engagement. Capillarity seeks to build an architecture that reflects radical humanism's emphasis on access and inclusion as a vehicle for classical humanism's emphasis on the individual expansion of potential and consciousness. The technical instrument whereby this program of humanist education may be deployed is mLearning

Multicultural Personality And Psychological Functioning, Lauren Trottier Jan 2013

Multicultural Personality And Psychological Functioning, Lauren Trottier

Electronic Theses and Dissertations

As the U.S. becomes increasingly diverse, individuals will need to interact effectively with a wide range of people. The theory of multicultural personality refined by Ponterotto (2010) proposes that some individuals may be better suited than others to adapt to the changing demographic landscape. Individuals with a multicultural personality are theorized to have the ability to interact effectively within a wide range of contexts and draw on diverse experiences and resources to solve everyday problems in multiple ways as well as seek out diversity in their lives. Because of their skills and disposition, Ponterotto (2010) suggests that those with a …

Institutional Vs. Non-Institutional Sources Of Presidential Influence: Explaining Congressional-Presidential Relations In The Age Of Polarization, Derek Culp

Electronic Theses and Dissertations

This thesis examines the determinants of presidential success with Congress. Seven essential sources of presidential power in the current era of party polarization were derived from the extant literature, and these factors were delineated into the institutional (formal) and non-institutional (informal) policymaking tools of the presidency. Variables that explain presidential legislative success include: intraparty support in Congress, the use of veto bargaining, executive orders and signing statements (institutional factors); as well as public approval, ‘going public,’ and strategic lobbying of Congress (non-institutional factors). Case studies of the presidencies of Bill Clinton and George W. Bush analyze the role of these …

Unintentionally Unethical: How Uncivil Leaders Violate Norms And Hurt Group Performance, Christopher Coultas

Electronic Theses and Dissertations

Incivility is a common form of low-grade aggression that lacks a clear intent to harm, that violates community norms and values for interpersonal conduct, and is often chronic in nature (Andersson & Pearson, 1999; Cortina, Magley, Williams, & Langhout, 2001). Because of its subtleties, it is difficult at times to detect and even more difficult to prevent. However, it is an essential phenomenon to research, due to its ubiquity and negative impact on worker outcomes such as job satisfaction and psychological health (Cortina et al., 2001). Incivility instigated by those in authority may be an even bigger problem, due to …
