Principals' Perceptions Of Working With Suburban Elementary Students From Poverty, Kathryn M. Schafermeyer

Graduate Research Theses & Dissertations

The increase of poverty in suburban communities since the year 2000 has fundamentally changed the work of elementary school principals in suburban schools. Using a qualitative method, 10 suburban elementary school principals from the Chicago metropolitan area were interviewed to gain a deeper understanding of their perceptions of working with suburban elementary school students from poverty. Principals revealed that they see poverty as having a deficit influence on suburban elementary students. They defined that they see the role of principal as helping students gain from the school experience by reducing the obstacles to learning that poverty presents and, therefore, providing …

Helping Users Learn About Social Processes While Learning From Users : Developing A Positive Feedback In Social Computing, Venkata Sai Sriram Pillutla

Graduate Research Theses & Dissertations

Social computing is concerned with the interaction of social behavior and computational systems. From its early days, social computing has had two foci. One was the development of technology and interfaces to support online communities. The other was to use computational techniques to study society and assess the expected impact of policies. This thesis seeks to develop systems for social computing, both in the context of online communities and the study of societal processes, that allow users to learn while in turn learning from users. Communities are approached through the problem of Massive Open Online Courses (MOOCs), via a complementary …

High Let Radiation Modulates Autophagic Flux In Glioblastoma Cells, Van Ai Bui

Graduate Research Theses & Dissertations

Glioblastoma (GBM) are highly malignant brain cancers that arise from the astrocytes of the brain. A diagnosis of GBM forecasts a poor prognosis even with the prescription of aggressive therapy consisting of surgery and radiation therapy with temozolomide. The average survival time with therapy is only 15 months with near universal recurrence. New therapeutic approaches are urgently needed to overcome recurrence. Radiation therapy is a highly effective treatment modality prescribed for brain cancer. Energy metabolism is altered in cancer cells and GBM in particular compared to normal surrounding cells. A major adaptation to the altered metabolism in GBM cells is …

Hillary Rodham Clinton's Campaign Narrative And The Perceptions Of The American People, Paige Russell

Graduate Research Theses & Dissertations

Hillary Rodham Clinton has led a prolific political career despite intense media scrutiny and a harrowing race for the presidency. There is a lack of research that specifically focuses on Clinton's rhetoric during the campaign and how voters have perceived the truth of her words. This study utilizes the narrative paradigm to understand Clinton's campaign narrative and the double binds she was forced into. The overall goal of the study is to establish these obstacles in four campaign narrative themes. By examining the perceptions of validity within Clinton's rhetoric we seek to determine the gendered impacts of running for President …

The current study was designed to reveal more fully the student perception of social presence within an online cohort. The research described in the current paper was a phenomenological study designed to examine the experiences of seven students who had graduated with master's degrees from an online cohort program. Specifically, the research examined students' perception of social presence through the lens of the Community Inquiry model, along with social cognitive theory, to determine the factors that might influence the levels of social presence in an online cohort. …

Empowering Courts In Corporate Law, Julian Velasco

Journal Articles

Corporate law recognizes the twin duties of care and loyalty, but treats the two very differently. Cases involving the duty of care receive very deferential review under the business judgment rule, if any at all, in light of exculpation provisions in corporate charters, while cases involving the duty of loyalty receive more demanding review under the entire fairness test. A fiduciary has the duty to act in the interests of the beneficiary in all relevant respects." In other words, both care and loyalty, as well as any other fiduciary duties that exist, are all merely aspects of the one overarching …

Coordinating Compliance Incentives, Veronica Root

Journal Articles

In today’s regulatory environment, a corporation engaged in wrongdoing can be sure of one thing: regulators will point to an ineffective compliance program as a key cause of institutional misconduct. The explosion in the importance of compliance is unsurprising given the emphasis that governmental actors — from the Department of Justice, to the Securities and Exchange Commission, to even the Commerce Department — place on the need for institutions to adopt “effective compliance programs.” The governmental actors that demand effective compliance programs, however, have narrow scopes of authority. DOJ Fraud handles violations of the Foreign Corrupt Practices Act, while the …

Religious Freedom And Recycled Tires: The Meaning And Implications Of Trinity Lutheran, Richard W. Garnett, Jackson C. Blais

Journal Articles

The Supreme Court's decision in Trinity Lutheran clearly affirmed a First Amendment rule against anti-religious discrimination. At the same time, it raised or left open a number of important and interesting questions about education reform, the relevance of anti-Catholic bias to states' so-called Blaine Amendments, and the sharpening tension between religious freedom and the application of antidiscrimination laws.

Metaphorical, Punitive, And Pedagogical Blindness In Hell, Meghan Henning

Books and Book Chapters by University of Dayton Faculty

What is the role of the blind body in hell? Does it gesture to broader cultural conceptions of physical impairment? Can the blind be healed in places of eternal punishment? Does this ‘healing’ function similarly to the understandings of blindness available in contemporaneous medical texts? This article will examine the depictions of the blind in the extra-canonical apocalypses that describe hell. We will begin with a discussion of the apocalyptic tours of hell that describe blindness, paying special attention to the different roles (metaphorical, punitive, and pedagogical) that blindness plays in each text. We will also consider the impact that …

Biomimetic Devices To Drive A Thermodynamically Uphill Reaction Using Light And To Degrade Industrial Waste Stream Components, Madison Joanne Sloan

Theses and Dissertations--Chemistry

Given the amount of industrial waste produced each year, as well as the accruing amount of greenhouse gases in our atmosphere produced by the burning of fossil fuels, it is imperative that humanity develop environmentally-sustainable sources of energy and methods of remediation. Nature achieves both of these by use of enzymes as catalysts, inspiring interest in designing biomimetic systems capable of harnessing clean energy and remediating industrial waste. This study examined the ability of enzymes in electrochemical and convective flow systems to achieve these tasks. The first portion studied the incorporation of enzymes into an electrochemical system to drive the …

Oxidative Stress And Proteomic Studies Of Mammalian Models Of Age-Related Metabolic Dysfunction In Neurodegenerative Disorders, Aaron M. Swomley

Theses and Dissertations--Chemistry

Expression proteomics is the field of science wherein proteins that make up the cellular proteome are identified both by name and by fold-change. Depending on the application of proteomics, this change in level could be due to internal cellular stressors or introduction of xenobiotics. Global oxidative stress measures use immunohistochemistry to determine the relative level of oxidative stress of macromolecules within the cell. In this dissertation, both global oxidative stress measures and expression proteomics were used in a variety of mammalian models in order to determine the effects of protein upregulation, intranasal insulin administration, and resveratrol supplementation on the cellular …

Mechanisms Of Heterogeneous Oxidations At Model Aerosol Interfaces By Ozone And Hydroxyl Radicals, Elizabeth A. Pillar-Little

Theses and Dissertations--Chemistry

Atmospheric aerosols play an important role in climate by scattering and absorbing radiation and by serving as cloud condensation nuclei. An aerosol’s optical or nucleation properties are driven by its chemical composition. Chemical aging of aerosols by atmospheric oxidants, such as ozone, alters the physiochemical properties of aerosol to become more hygroscopic, light absorbing, and viscous during transport. However the mechanism of these transformations is poorly understood. While ozone is a protective and beneficial atmospheric gas in the stratosphere, it is a potent greenhouse gas in the troposphere that traps heat near the Earth’s surface. It also impacts human heath …

Semiconductor Photocatalysis: Mechanisms, Photocatalytic Performances And Lifetime Of Redox Carriers, Ruixin Zhou

Theses and Dissertations--Chemistry

Photocatalytic reactions mediated by semiconductors such as ZnS, TiO₂, ZnO, etc. can harvest solar energy into chemical bonds, a process with important prebiotic and environmental chemistry applications. The recycling of CO₂ into organic molecules (e.g., formate, methane, and methanol) facilitated by irradiated semiconductors such as colloidal ZnS nanoparticles has been demonstrated. ZnS can also drive prebiotic reactions from the reductive tricarboxylic acid (rTCA) cycle such as the reduction of fumarate to succinate. However, the mechanism of photoreduction by ZnS of the previous reaction has not been understood. Thus, this thesis reports the mechanisms for heterogeneous photocatalytic reductions …

Interactions Of Compounds Containing Group 12 And 16 Elements, Daniel Burriss

Theses and Dissertations--Chemistry

The focus of this dissertation is on the interactions of compounds containing group 12 and 16 elements. This work is presented in three major parts. First, the interaction of the synthetic dithiol N,N’-bis(2-mercaptoethyl)isophthalamide), abbreviated BDTH₂, with selenite. Second, the interaction of cysteine with Cd(II) and the biologically relevant Cd-Cysteine crystal structure. Third, the green synthesis of CdSe quantum dots (QDs).

The interaction of BDTH₂ with selenite is different from the interactions with other metals and metalloids previously studied. Under ambient conditions, BDTH₂ is oxidized to the disulfide, BDT(S-S), while selenite is reduced to elemental selenium. However, …

Epigenetic Modifications To Cytosine And Alzheimer’S Disease: A Quantitative Analysis Of Post-Mortem Tissue, Elizabeth M. Ellison

Theses and Dissertations--Chemistry

Alzheimer’s disease (AD) is the most common form of dementia and the sixth leading cause of death in the United States, with no therapeutic option to slow or halt disease progression. Development of two characteristic pathologic lesions, amyloid beta plaques and neurofibrillary tangles, in the brain are associated with synaptic dysfunction and neuron loss leading to memory impairment and cognitive decline. Although mutations in genes involved in amyloid beta processing are linked to increased plaque formation in the inherited familial form of AD, the more common idiopathic form, termed sporadic AD, develops in the absence of gene mutations. In contrast, …

Three Essays In Health Economics, Abraham Abebe Asfaw

Graduate Research Theses & Dissertations

This dissertation constitutes three separate essays in health economics. The first essay examines whether Medicare Part D led to changes in the health behaviors that are essential to manage chronic diseases. Using data from the Medical Expenditure Panel Survey, I find that the implementation of Medicare Part D reduces the probability of engaging in physical exercise. The effect on dieting is inconsistent across different specifications and the effect on cigarette smoking is not statistically significant. The negative physical exercise effect of Medicare Part D is more pronounced among patients with low educational attainment. The second essay looks into whether early …

A Trauma Analogue Study Investigating The Role Of Attentional Shifting In Emotion Regulation, Melissa J. London

Graduate Research Theses & Dissertations

Trauma-focused research has shown that high attentional control serves as a buffer against posttraumatic stress symptoms and other pathology. However, less is known in regard to the influence of attentional processes on the effectiveness of treatment strategies used to reduce symptoms. The current project used an analogue design to examine the impact of participants' ability to flexibly shift attention on the effectiveness of two prominent emotion regulation strategies in managing distress and trauma-related symptoms (i.e. negative affect, intrusive thoughts, and avoidance). Undergraduate students ( N = 153) completed a dot-probe task incorporating stimuli that elicit negative emotions and trauma-related stimuli …

Voices Of Latina/O Parents : Sending A Child To College, Karla Neal

Graduate Research Theses & Dissertations

Latinas/os are one of the immigrant and ethnic groups with the lowest percentages of educational attainment (Lopez & Fry, 2013) and financial mobility (Erisman & Looney, 2007) in the United States. The purpose of this qualitative research study was to develop a better understanding of the perceptions and experiences of Latina/o parents who have college-age children who have moved away from home to college to pursue a higher education degree. While parents have been identified as an important influence for Latina/o student academic success in college; there is little knowledge about their experiences and perceptions related to education and the …

By using qualitative research method, especially case study, and developmental rent management analysis framework, the author analyzed the development in three different time periods since the Chinese economic reform in 1978. Case studies of learning period, developing period and new Chinese owned enterprises after joining WTO presented different policies and rent management strategies arranged by the state to industrialize and develop the modern Chinese automobile industry. Although there are failures involved in the arrangement, China finally industrialized and developed its modern automobile industry and became the world's …

Competition And Community Interactions Of Two Generalist Herbivores, Elizabeth Ellen Barnes

Electronic Theses and Dissertations

Competition can have far-reaching consequences for the fitness and distribution of many organisms. In herbivorous insects, competition mediated by a third organism is more common than direct competition and has a strong effect on insect communities; yet most research on indirect competition among herbivores focuses on dietary specialists, and those studies that do include generalists tend to rear them on agricultural crops. My project examines species interactions at three levels: intraspecific competition (within species), interspecific competition (between species), and ecosystem engineering effects at the community level. I studied competition and community interactions of two temporally-separated species of herbivorous insects, western …

Formulation And Characterization Of Poly(Β-Amino Ester) Networks For Controlled Delivery Of Antioxidants In Pharmaceutical Applications, Vinod Shivaji Patil

Theses and Dissertations--Chemical and Materials Engineering

Oxidative stress, which reflects an imbalance between oxidants and endogenous antioxidants, is known to be a cause as well as an effect of health conditions such as cancer, diabetes, Alzheimer’s disease, Parkinson’s disease and ischemia-reperfusion injury. Antioxidants have shown promising results in vitro in controlling oxidative stress. However, years of in vitro studies have failed to translate into effective clinical interventions for controlling oxidative stress in the disease conditions. This has been due to low bioavailability and lower stability of antioxidants. Poly(antioxidant β-amino esters) (PABAE) are a recently-developed class of biodegradable polymeric hydrogels that have shown promise in their ability …

Functionalization Of Silver Nanoparticles On Membranes And Its Influence On Biofouling, Conor G. Sprick

Theses and Dissertations--Chemical and Materials Engineering

Ultrafiltration (UF) processes are often used as pretreatment before more retentive/costly processes, such as nanofiltration and reverse osmosis. This study shows the results of low-biofouling nanocomposite membranes, loaded with casein-coated silver nanoparticles (casein-Ag-NPs). Membranes were cast and imbedded with Ag-NPs using two approaches, physical blending of Ag-NPs in the dope solution (^PAg-NP/CA membranes) and chemical attachment of Ag-NPs to cast membranes (^CAg-NP/CA membranes), to determine their biofouling control properties. The functionalization of Ag-NPs onto the CA membranes was achieved via attachment with functionalized thiol groups with the use of glycidyl methacrylate (GMA) and cysteamine chemistries. The …

Nutritious Meals For The Homeless Population: Challenges And Opportunities, Kayla A. Albrecht

Masters Theses

Objective: Consuming a nutritionally adequate diet is extremely challenging for the homeless population. Though meals are available to the homeless population through soup kitchens and homeless shelters, these settings often do not serve meals that provide essential nutrients. The consumption of energy-dense, low-nutrient foods has led in part to high prevalence of obesity, heart disease, and chronic illnesses among the homeless. The purpose of this study was to (a) examine the challenges that homeless shelters face in providing nutritious meals to guests and (b) investigate the need and interest of nutrition education at homeless shelters.

Methods: Nine homeless shelter directors …

Arsenic Removal With A Dithiol Ligand Supported On Magnetic Nanoparticles, John Hamilton Walrod Ii

Theses and Dissertations--Chemistry

Exposure to arsenic (As) in water, the ubiquitous toxin that poses adverse health risks to tens of millions, is the result of both anthropogenic and geochemical mobilization. Despite recent publicity and an increased public awareness, the dangers associated with arsenic exposure rank among the top priorities of public health agencies globally. Existing sequestration applications mainly include reductions and adsorption with zero-valent metals and their oxides. The performance of adsorption media is known to preferentially favor aqueous As(V) over As(III) due to the charge of the dissolved oxyanion. Magnetic nanoparticles (MNP) have been the focus of multidisciplinary research efforts for the …
