Mothering The Aggressive Child, Katja Ermann

PsyD Program in Clinical Psychology Doctoral Dissertations (Seattle)

This qualitative study explores the experience of mothers parenting significantly aggressive children, ages five to 10. Little has been known previously about how women experience this aggression or the social and psychological impacts it has on them. This dissertation highlights the women’s understandings to provide a solid basis for theoretical explication using a Constructivist Ground Theory approach. Significant findings include the invisibility and stigma the women feel and the ways in which the experience is similar and dissimilar to other forms of family violence, particularly adolescent-on-parent violence (APV). Differences were found in social stigma between women whose child has a …

Molecular Mechanism Of Neurodegeneration Induced By 4-Nonylphenol, Michelle Alejandra Aranda

Open Access Theses & Dissertations

Neurodegeneration, a progressive loss of nerve cells, occurs in many neurological disorders, including Alzheimer's disease (AD) and Parkinson's diseases (PD), as well as in dementia. The pathogenesis of these diseases is unknown, and recent evidence suggests that environmental factors, which act as endocrine-disrupting compounds (EDCs) could play a significant role in developing the disease process. 4-Nonylphenol (4-NP), an EDC, and a ubiquitous environmental toxin has been shown to affect brain development and may cause neurodegeneration. 4-NP is produced in large quantities in the U.S. and used as raw materials for making detergents, pesticides, plastics, paints, cosmetics, rubber, and other industrial/household …

The Implications Of Gender Roles On Hiv Risk Behaviors And Latinas' Hiv Risk Perception Among A College Sample, Juliana De Almeida Cardoso Smith

Open Access Theses & Dissertations

The primary aim of the proposed research was to investigate the moderating effects of gender roles in regards to HIV sexual risk behaviors and HIV risk perception. Human Immunodeficiency Virus (HIV) remains a serious public health concern that affects an estimated 1.2 million individuals in the United States, disproportionately affecting ethnic minorities. We hypothesize that gender roles will significantly moderate the relationship between HIV sexual risk behaviors and HIV risk perceptions. Additionally, we hypothesize that while subordinate marianismo and perceived partner's negative machismo will not moderate the relationship between HIV sexual risk behaviors and HIV risk perceptions by themselves; their …

Cradle To Grave Lifecycle Process Analysis For Transuranic Waste Management Los Alamos National Laboratory, Cesar Enrique Dominguez

Open Access Theses & Dissertations

Amid World War II, in the late 1930s, nuclear fission was discovered. This revolution gave way to the development of nuclear technologies, including the world's first atomic bomb; these advancements in nuclear research left behind radioactive waste. Radioactive waste is known as the byproduct of nuclear reactors, fuel processing plants, hospitals, nuclear research facilities, as well as the result from the decommissioning and dismantling of radiation-exposed buildings and materials. This byproduct may be dangerous to workers, the public, and the environment and must, therefore, be handled with utmost safety. Given this, radioactive waste must be processed, stored, and disposed of …

Manfreda Maculosa Leaf Extracts And Their Effects On Whole And Selected Myotoxic Components In Crotalid Venom, Charles Steven Gilbert

Open Access Theses & Dissertations

Manfreda spp have been used for the treatment of snakebite by several cultures in North and Central America (Austin & Honychurch, 2004, Johnson, 1999, Moerman, 2008, Verhoek, 1978a). There has been no systematic study of the genus Manfreda for its usefulness in the treatment of snakebite.

While the annual incidence of snakebite in the United States is relatively low (approximately 8,000 - 10,000), with a low mortality rate of 5 - 6 cases per year, there is still significant morbidity associated with snakebite (CDC - NIOSH, 2018, Springhouse Corp (eds), 2005). Worldwide numbers of the cases of snakebite can only …

Neuromuscular Electrical Stimulation: A Novel Treatment Intervention For Improving Metabolic Health In An Overweight/Obese Population, Michelle J. Galvan

Open Access Theses & Dissertations

Background: Most U.S. adults (80%) do not meet minimum exercise recommendations by ACSM (CDC, 2015). Using an in vitro primary cell culture model, we and others have shown that muscle contraction induced by electrical stimulation results in increased glucose transporter 4 (GLUT4) protein, glucose uptake and mitochondrial content. Neuromuscular electrical stimulation (NMES) is a novel alternate strategy to induce muscle contraction, using electrical impulses. However, effectiveness of NMES induced muscle contraction to improve insulin sensitivity and energy expenditure is not clear. The purpose of this study was to investigate the effects of four weeks of NMES on insulin sensitivity in …

80% of the people living with a disability live in developing countries (WHO 2018). With this being said, there is limited social research examining the experiences of this population (Connell 2011; Meekosha 2011). This Thesis seeks to gain an understanding of the broad functions of a lower-limb prosThesis through the lived experiences of people living in México. Through the use of qualitative data collected from participants living in Oaxaca, Guadalajara, Mexico City, and Cuernavaca, the conversation on the "functionality" of a prosthetic limb has been expanded to include the social function that the prosThesis serves in the roles of navigating …

Differences In The M1 And M2 Macrophage Subtypes Between The Sexes Determine Susceptibility To Francisella Tularensis Infection, Michelle Arlene Sanchez

Open Access Theses & Dissertations

Francisella tularensis is the causative agent of the human disease tularemia. It is highly infectious with as few as 10 microorganisms via inhalation causing a lethal infection. F. tularensis infects a variety of cell types, including macrophages and neutrophils, since it needs to enter, survive and proliferate in order to cause pathogenicity. Disease is the result of over activating the host's own inflammatory response initiated by the macrophage's response to infection.

Known differences exist in the intensity of the inflammatory response between the sexes which leads to differences in sensitivity to autoimmune and infectious disease. Males tend to be more …

Thermal Characterization Of Abs/Carbon Fiber, Abs/ Glass Fiber And Petg/Glass Fiber Reinforced Composites Used In Large Area Additive Manufacturing, Fernando Adrian Rodriguez Lorenzana

Open Access Theses & Dissertations

Additive manufacturing has seen continuous advancements, such as the inclusion of large-area additive manufacturing extrusion systems. These systems precede small-scale 3D printing by means of research and technological development for the manufacturing of plastic and fiber industries. Big Area Additive Manufacturing (BAAM), a material extrusion process, is capable of 3D printing large parts using thermoplastic composites by adding fiber reinforcements. The incorporation of fibrous materials, carbon fiber (CF) or glass fiber (GF), is a common practice in which percentage nominal ratios of fiber reinforcement by weight are implemented to the polymer matrix. In general, this enables warpage reduction during printing, …

Validating A Masculinity Scale In A Non-College Sample, Rubi Gonzales

Open Access Theses & Dissertations

Sexual assault in the United States is prevalent. One out of every six American women has been the victim of an attempted rape or complete rape. Previous research demonstrates that hypermasculine attitudes are positively predictive of sexual aggression toward women. In these studies, researchers have continued to utilize outdated and inappropriate measures like the Hypermasculinity Inventory (1984) to assess hypermasculinity. Measures that assess hypermasculinity have only been validated on college samples. A modern measure of masculinity is the Auburn Differential Masculinity Inventory-23 (Burk, Burkhart, & Sikorski, 2004), which has been validated in college samples. The present research evaluated the psychometric …

Directory Of Services And Resources To Support Breastfeeding Initiation, Exclusivity, And Longevity In The El Paso Texas Region, Tiffany Nichelle Butler

Open Access Theses & Dissertations

Human milk is recognized as the ideal food for infants; however, in order for human milk to get to the infants, breastfeeding requires the support of the healthcare system. Among infants born in 2015 in United States, 4 out of 5 started to breastfeed and despite of this high rate, only 22% of mothers exclusively breastfed for 6 months. The decisions to breastfeed are influenced by multiple factors including breastfeeding education and support, hospital practices, and participating in tailored education programs. The Office of the Surgeon General has identified the need for healthcare systems to "guarantee continuity of skilled support …

The Battle Off The Battlefield: Exploring Medical Cannabis Use Among U.S. Veterans Looking For Relief, Viridiana Edwards

Open Access Theses & Dissertations

This study analyzed the reasons U.S. veterans use cannabis, focusing on what ways cannabis is socially acceptable, what ways it is viewed as deviant, and to what extent veterans are using cannabis for pain and/or mental relief. To answer these questions, an open and closed ended questionnaire was created and was available online. My results showed that U.S. veterans were using medical cannabis due to the negative side effects from the pharmaceutical medication that they were prescribed, physicians not listening to them during their appointments, and for social integration.

Trypanosoma Cruzi Trypomastigote Glycosylphosphatidylinositol-Anchored Mucins And A Synthetic Alpha-Gal-Containing Neoglycoprotein As Potential Biomarkers And Vaccines For Chagas Disease, Igor Leandro Estevao

Open Access Theses & Dissertations

Chagas disease (CD), caused by the protozoan Trypanosoma cruzi, is a neglected tropical disease that kills or permanently disable thousands of people annually. About 6-8 million people are estimated to be infected worldwide. Although many efforts have been made for the development of an effective immunotherapy, currently there is no vaccine to prevent or treat CD in humans. Despite their toxicity, the two current drugs for CD, benznidazole (BZN) and nifurtimox (NFX), have medium-to-high efficacy in the chronic stage of the disease and could save or improve the lives of thousands of patients. However, negative seroconversion in treated patients, as …

A Coupled Modeling Framework For Allocation Design In Land-Use And Land-Cover Changes To Optimize Biofuel Feedstock Production, Ana C. Cram

Open Access Theses & Dissertations

Environmental awareness has increased the demand for renewable energy. Notably, the production of biofuels from feedstock is gaining interest as a viable measure to reduce fossil fuels consumption. Nevertheless, it is crucial to identify the trade-offs between bioenergy crop cultivation and the environmental impact on land, water, and atmosphere.

Intensifying biofuel cultivation trigger effects associated with Land Use and Land-use-change, which are complex to assess. While hydrological models had been used to investigate the environmental impacts of land-use changes on water and soil quality, their quantitative assessment is often incomplete. Changes in land use and agricultural activities also contribute to …

Examination Of Sex Differences And The Role Of Ovarian Hormones In Modulating Nicotine Withdrawal In Rats, Rodolfo Jesus Flores Garcia

Open Access Theses & Dissertations

Introduction: Aim 1 characterized sex differences and the role of ovarian hormones in physical signs and negative affective states produced by nicotine withdrawal in female, ovariectomized female (OVX), and male rats. We also compared nicotine withdrawal and corticosterone levels with estradiol (E2) and progesterone across the 4-day estrous cycle. Aim 2 validated the role of ovarian hormones in withdrawal in OVX females that received vehicle, E2, or E2+progesterone. Methods: Female rats received a sham surgery or an ovariectomy procedure. Fifteen days later, all rats were implanted with a pump that delivered nicotine for 14 days. On the test day, separate …

Patient Perception In Quality Of Health Care In Civilian And Military Hospitals, Rodolfo Gonzalez Garza

Open Access Theses & Dissertations

The purpose of this research is to examine and relate Erving Goffman's theory and concept of total institution to the perceived experienced quality of health care that occurs in the treatment of patients, in both preoperative and postoperative surgical procedures, at civilian and military hospitals. Goffman argues that there is a distinct relationship between the medical staff and patients at the hospitals. The staff most often feels superior and correct in their actions, while the patients perceive themselves as weak, inferior, and defenseless. In my thesis, I use a qualitative method approach to determine how veteran patients perceive their quality …

The Effects Of Eccentric Overload Bench Press Training On 1rm Performance And Emg Activity In Powerlifters, Lance Dakota Gruber

Open Access Theses & Dissertations

For powerlifters, bench press performance is directly related to success in competitions since it is one of the three main lifts performed during a powerlifting competition. For a powerlifter to be competitive, they must train efficiently, building strength as quickly and safely as possible. Research has shown that eccentric training elicits greater strength increases when compared to concentric training. Furthermore, previous research observed that eccentric overload training for the lower limbs resulted in not only significantly improved strength, but it also takes place at a faster rate than traditional training. However, there is a lack of research on whether the …

Novel Maximum Entrophy Method For The Average Survival Time Differences Between Two Groups, Joscelyne Guzman - Gonzalez

Open Access Theses & Dissertations

We suggest a Maximum Likelihood estimator for the Average Survival Time Difference between two groups, based on the extra time in which should be added to one group to produce the maximum entropy of the result. The estimator is calculated only from time to event data, does not assume hazard proportionality and provides directly the magnitude of the clinical differences between the groups. Our Monte Carlo simulations show that, even at low sample numbers the estimator is a reliable predictor for the clinical differences between the groups, and therefore can be used to estimate from preliminary data whether or not …

Interactions Of Bacterial Communities With Hydrous Sulfate Minerals In Water-Restricted Gypsic Environments: A Case Study Based In The White Sands National Monument, Brandon Nicholas Lajoie

Open Access Theses & Dissertations

Microbial communities have been commonly found to survive and thrive in arid to hyper-arid gypsic environments that are considered hostile to most other forms of life. The mechanisms through which microbes have conquered these harsh environments remain poorly understood. Here I hypothesize that the microbial communities in water-restricted gypsic settings could benefit in terms of energy and water sources via their interactions with the abundant hydrous sulfate minerals [i.e., gypsum (CaSO4·2H2O)] that build up these niches. Gypsum is of high bio-relevance because its sulfate component may be used as electron acceptor by sulfate-reducing bacteria and the crystallization water may be …
