Primary Drug And Multidrug Resistant Tuberculosis, Of The Diagnostic Properties Of The Sputum Smear Versus Culture Method For Tuberculosis Diagnosis In An Ecuadorian Urban Public Health Facility, Sandra Luz Groeschel

Open Access Theses & Dissertations

Background: The accurate diagnosis and effective prevention and control of tuberculosis (TB) are major global public health challenges. Ecuador has among the highest documented TB incidence (59/100,000 inhabitants) and mortality rates in the Americas region (27/100,000 inhabitants). In addition, TB multi-drug resistance is becoming increasingly common. The culture method is the preferred method of choice for diagnosing TB in the United States and many other high resource countries due to its high documented sensitivity. An added benefit of the methods is that it also can be used to detect primary TB resistance. In contrast, despite its lower diagnostic sensitivity, …

Reduced-Order Modeling Using Orthogonal And Bi-Orthogonal Wavelet Transforms, Miguel Hernandez Iv

Open Access Theses & Dissertations

It is well known that model reduction methods borrow techniques typically found in data compression, and current state-of-the-art techniques for data compression are based on the wavelet transform. Given these facts, it is surprising that model reduction using wavelets has not received much attention and has not been adequately addressed in the literature. This research seeks to determine if wavelets can be used for model reduction and if wavelet model reduction is a viable alternative to existing model reduction methods.

In this work we propose a novel method for model reduction using wavelets. Specifically, we introduce techniques for deriving wavelet …

The Effect Of Co-Witness Information And Individual Differences In Cognitive Abilities On The Suggestibility Of Pre-School Children, Rachell Leanne Jones

Open Access Theses & Dissertations

Despite nearly 25 years of research, psychologists are still learning new ways in which various demographic, psychological, social, and cognitive factors contribute to child suggestibility. Numerous facets of each area have been studied independently, but as a field, it is becoming apparent that suggestibility is also affected by complex interactions between these various components (Scullin, Kanaya, & Ceci, 2002). The current study investigated several forensic interviewing techniques and psychosocial and cognitive factors that were hypothesized to influence child suggestibility. One hundred children were randomly assigned to five interview conditions after viewing a live event. The supposed statements of a co-witness …

Motivations For A Source To Resist An Interrogation: Consequences To The Self Versus Consequences To An Other, Julia Labianca

Open Access Theses & Dissertations

The current research investigated the effect of situational and dispositional factors on a source's decision to confess guilty knowledge of another's actions to an interrogator. The extant literature suggests that potential consequences to the self are a major motivator for decisions to confess or resist an interrogation. Previous research also suggests that the potential consequences to the other person may also influence a source's motivations to confess guilty knowledge. Additionally, personality measures related to interdependence versus personal independence (collectivism and individualism) and individual loyalty may also influence a source's motivations to cooperate with or resist an interrogation. However, few experiments …

Method Development For A Chemical And Biological Analysis Of Glucocorticoids In Wastewater, Maria Carmen Lozano

Open Access Theses & Dissertations

Glucocorticoids are a class of steroid hormones that can either be produced synthetically or naturally by the adrenal glands. The synthetic glucocorticoids are highly prescribed in the United States for their anti-inflammatory and immunosuppressive properties to treat a variety of ailments and diseases; however, these have been implicated in a number of adverse human conditions such as obesity, metabolic syndrome, immune-suppression, delayed puberty, adrenal insufficiency and Cushing Syndrome, among others. Ongoing research has shown that synthetic and natural hormones are transported to aquatic environments via mammalian excretion or wastewater effluent, and as a result, the release of glucocorticoids into the …

Complexity Of Affective Disposition And Reflective Transphenomenality: An Exploratory Study Of Middle School Mathematics Teacher And Student Self-Positioning And Positioning-By-Others Toward Mathematics, Mathematics Teaching, And Learning, Ruby Lorilee Lynch-Arroyo

Open Access Theses & Dissertations

The purpose of the mixed methods study was to examine the phenomenon of transphenomenal simultaneity between teacher and student disposition that contributed to the phenomenological conflict of teacher self-positioning and positioning-by-others toward mathematics, mathematics teaching and learning. The intent was to provide a view of self-reported and observed middle school teacher and student experiences in mathematics, based on the analysis of affective dispositional characteristics within the context of its complexity.

There is evidence that documents a relationship between teacher and student disposition, but to what extent and encompassing what characteristics and factors has not been sufficiently substantiated. Beyers (2011) identified …

In-Situ, Integrated U-Pb, Hf And O Isotopic Study Of Igneous, Metamorphic And Detrital Zircons. Implications To Crustal Evolution And Geodynamics, Munazzam Ali Mahar

Open Access Theses & Dissertations

Zircon data from South Karakoram gneiss dome provide evidence for Proterozoic inherited cores (1.8-1.9 Ga and 2.3-.2.5 Ga) surrounded by migmatitic overgrowth with ages ranging from ~6 to ~20Ma. Oxygen isotopic data of Neogene migmatite and inherited core is similar and indistinguishable ranging from 7.5 to 9.5 /. However, Neogene overgrowth is significantly less evolved than the inherited core in terms of Hf composition. This implies that the Hf composition of the migmatitic zircons is not controlled exclusively by the dissolution of the inherited cores and that contamination by external melts is likely. Isotopic data from the Baltoro plutonic unit …

Nanocomposite And Mechanically Alloyed Reactive Materials As Energetic Additives In Chemical Oxygen Generators, Marco Antonio Machado

Open Access Theses & Dissertations

Chemical oxygen generators are widely used for aircraft, spacecraft, submarines, and mine rescue. Oxygen-generating compositions typically include alkali metal chlorate or perchlorate that decomposes at increased temperatures, a transition-metal oxide as a decomposition catalyst, and a metal fuel that reacts with part of the produced oxygen to provide heat for a self-sustained propagation of the decomposition/combustion wave. To increase the oxygen yield per unit mass, it is of interest to minimize the amount of metal fuel, but decreasing its content leads to pulsating combustion and undesired fluctuations of the oxygen flow rate. This work explores the feasibility of replacing iron …

Endocrine Disrupting Compound 4-Nonylphenol And Neurodegeneration, Jessica Martinez Jurado

Open Access Theses & Dissertations

Neurodegeneration, a progressive loss of nerve cells (neurons), occurs in many neurological disorders including Alzheimer's disease, Parkinson's disease, Schizophrenia, and drug addiction. Cytoskeletal disruption in neurons and aggregation of proteins associated with these disorders is the hallmark of neurodegeneration. However, the cause of neurodegenerative disorders is unknown and currently there are no effective drug treatments. Aging is the most consistent risk factor for developing a neurodegenerative disorder, and recent evidence suggests that environmental factors, which act as endocrine disruptors, pose a risk in the disease process. 4- nonylphenol (4-NP), an endocrine-disrupting compound (EDC), has been shown to affect brain development …

Microstructure And Mechanical Properties Of Titanium Nitride Optical Coatings Made By Dc Magnetron Sputtering, Gustavo Martinez

Open Access Theses & Dissertations

Titanium nitride (TiNx) thin films were grown by DC (Direct Current) magnetron sputtering method onto Si(100) substrates by varying time of deposition to produce films with variable thickness (dTiN) in the range of 20-120 nm. The grown TiNx films were characterized by studying their structure, composition, and mechanical properties. Nuclear reaction analysis (NRA) combined with Rutherford backscattering spectrometry (RBS) analyses indicate that the grown films were stoichiometric TiN. Grazing incidence X-ray diffraction (GIXRD) measurements indicate that the texturing of the TiN films changes as a function of dTiN. The (111) and (002) peaks appear initially; with increasing dTiN, (111) becomes …

Cross-Border Mobility, Access To Healthcare Through Health Coverage, And Other Correlates For Utilization Of Healthcare Services Along The U.S.-Mexico Border, Krystal Martinez

Open Access Theses & Dissertations

BACKGROUND: At the national level, Hispanics suffer from poor health coverage. This is amplified in Texas, which has the highest percent (26.3%) of uninsured individuals in the U.S., and further augmented in El Paso, TX. In some border states and counties, barriers to healthcare include medically underserved areas, low-income, and the recent immigration among the Hispanic population. Cross-border mobility has facilitated access to health services in Mexico. Despite this, there remain gaps in understanding utilization of healthcare services among Hispanics in El Paso, TX. AIMS & OBJECTIVES: The aims of this study are to: (1) describe access to healthcare through …

The Eolian-Sabkha Transition In The Permian Cedar Mesa Sandstone, Se Utah, Alexandra Massad

Open Access Theses & Dissertations

This study focuses on the depositional transition between the Permian Cedar Mesa sand dune sea and the adjoining fluvial, lacustrine, playa and a sabkha facies. This transition provides insights into how climate and environment interacted in this unique setting where up to 300 m of eolian sands transition into evaporites. The evaporites are less common as tongues within the eolianites than previously thought and there were several environments that were observed that haven't been previously described or observed in the Cedar Mesa. The arrangement of the various units within the study area support the climate control on stratigraphy.

Sumoylation Exerts Minimal Effects On The Splicing Regulatory Activity Of The Influenza A Virus Non-Structural Protein Ns1, Griselda Melendez

Open Access Theses & Dissertations

One of the greatest challenges facing the development of a universal treatment for influenza infection is the virus's ability to mutate rapidly and produce new antigenic properties. Targeting the viral components of one strain does not ensure that the treatment will be effective with a newly developed strain. One alternative would be to develop therapies that target cellular factors the virus depends on for survivability. One of these factors is the cellular SUMOylation system. We have previously demonstrated that the Small Ubiquitin-like MOdifier (SUMO) interacts with the influenza virus by SUMOylating several viral proteins and by affecting the interferon blocking …

Investigating The Validity Of A Survey Intended To Gauge Mathematics Problem-Solving Disposition Along The Impulsive-Analytic Dimension, Miguel Mendoza

Open Access Theses & Dissertations

This study investigates the validity of the Likelihood-to-Act (LtA) survey developed to assess respondents' problem-solving disposition along the impulsive-analytic dimension. Sixteen pre-service teachers were strategically selected from a pool of 495 LtA survey respondents to participate in a semi-structured task-based interview approximately one hour in length. The interview consisted of three main parts: a problem solving section, a consistency section, and a classification section.

* Part 1 of the interview was developed to get interviewees to solve five open-response problems meant to elicit an impulsive response. Interviewees were also asked to verbalize their thought process in order for the researchers …

The Effect Of Birth Order On Age At First Sex And Total Number Of Lifetime Sexual Partners, Lacey Christine Clark Anderson

Theses and Dissertations

Research in the field of birth order is expansive and has been used to explain many social processes, including the sexual behavior of young adults. However, results regarding the influence of birth order on risky sexual behavior are somewhat limited, sometimes contradictory, and often lack generalizability to larger populations. In this thesis, using

data from the National Health and Social Life Survey (1992) and multiple regression techniques, I investigate the influence of ordinal position on two measures of sexual behavior,age at first sex and total number of lifetime partners, among young adults age 18 to 30. Results show that birth …

Josephson Currents In Two-Gap Superconductor-Insulator- Superconductor Junctions, Ladan Bahrainirad

Theses and Dissertations

As a way to investigate the transport property of superconductor-insulator-superconductor (SIS) junction with two-gap superconductors such as MgB2 and iron superconductors, we study the microscopic structure of the Josephson current in a tunnel junction with a very narrow quasi-classical barrier. Also, the possibility of mid-gap states in two-gap superconductor is investigated, and their effects on the current-phase relation as well as the current density characteristics are studied. In the SIS break junction, mid-gap states appear at the Superconductor-Insulator interfaces due to an abrupt change in the superconducting order parameter, indicating that the two-gap superconductor SIS junction can yield a rich …

Climate Change And Ragweed Allergy Risk Assessment: A Study Of The Grand Forks Metropolitan Statistical Area, Shumila Rani Ahmad

Theses and Dissertations

Nowadays the association between anthropogenic climate change and public health is in the early stages of universal recognition. Yet one fundamental aspect that remains largely unappreciated is the impact of climate change on ragweed (Ambrosia species) biology and the ensuing pathophysiology of human systems. Ragweed pollen is one of the primary causes of seasonal pollen allergy in the world. Allergic reactions to ragweed pollen can range from mild hay fever to life-threatening asthma attacks. The aim of this thesis was to conduct a ragweed allergy risk assessment for the Grand Forks ND-MN Metropolitan Statistical Area (MSA).

The study area is …

Informal Alliance: Royal Navy And U.S. Navy Co-Operation Against Republican France During The Quasi-War And Wars Of The French Revolution, Jon Paul Eclov

Theses and Dissertations

The Quasi-War was an undeclared conflict fought between the young United States of America and the French Republic at sea during the years 1798-1801. It began when the French mounted a guerre de course against the significant American blue-water merchant marine in response to America concluding Jay's Treaty with Great Britain. At the time, the U.S. had no navy whatsoever with which to combat these French corsairs primarily operating from bases in the West Indies. Seeing there was little hope of immediately ending the matter diplomatically after the infamous XYZ Affair, President John Adams convinced a normally divided Congress to …

Epigenetic Patterns: Process-Driven Or Sequence-Driven?, Amanda Gefroh

Theses and Dissertations

Some of the most rapidly-evolving fields of study in the medical and research communities presently are those which investigate our genetic code, the elements and factors that control the expression of our genetic code, as well as fields of study which analyze theories about an organisms' physiology and phenotype from the information that both of the previous topics concomitantly provide. The work of the Milavetz lab, among many others, is striving to fill the gaps in knowledge about epigenetic regulation of biological processes - here by using the well-suited model virus, Simian Virus 40. It has for some time now …

Inhibition Of The Ysc Type Iii Secretion System Of Yersinia Pestis By Compound D And Interaction Of Type Iii Secretion System Needle Proteins With Host Receptors, Danielle L. Jessen

Theses and Dissertations

The type III secretion system of gram-negative bacterial pathogens is a major virulence factor and functions to modulate host immune responses. Immune modulation occurs in many ways, including direct injection of effector proteins or indirect methods such as the detection of bacterial components by host immune receptors. Knowledge of these immune modulations allows for development of treatment options in an ever-increasing antibiotic-resistance climate. The studies presented here explore both areas of immune modulation. We identify Compound D as a potent inhibitor of the type III secretion system of Yersinia pestis. Through evaluation of effector secretion by bacteria grown in the …
