Hydrologic Modeling With Remote Sensing For The Estimation Of Groundwater Resources Within The Sand River Catchment, South Africa, Sophia Bakar

Electronic Theses and Dissertations

The Sand River Catchment is an important tributary of the transboundary Limpopo River in South Africa, which spans Botswana, Mozambique, South Africa, and Mozambique. Groundwater is a critical resource in the region, especially in the context of population growth and climate change. Data are needed for proper management of these water resources. In regions where groundwater data are sparse in time, space, or both, the most promising solutions come from satellites and hydrologic models. Regional literature suggests that the Soutpansberg Mountains, located within the Sand Catchment, are high-elevation water towers with uncertain groundwater resources. Improved understanding of groundwater resources in …

Comparing The Effectiveness Of Traditional Taped-Problems Intervention With A Remote Delivery Version For Increasing Math Fact Fluency, Cortney Chelecki

Electronic Theses and Dissertations

The knowledge of math fact fluency skills is crucial for children to develop both related and subsequent necessary math skills. Students require fluency in basic math facts in order to successfully understand and perform more complicated math problems. Research has shown that students demonstrating math skill deficits are likely to have limited cognitive capacity to devote to higher math tasks, and also suffer from math-related anxiety, a lack of engagement, and limited vocational and career opportunities (Delli Sante et al., 2001; Gersten & Chard, 1999; Parkhurst et al., 2010; Poncy et al., 2007; Riconscente, 2013). During the COVID-19 pandemic, all …

Implications Of Individuals With Music Learning Experience Using A Segmented Multimedia Lesson In A Non-Music Discipline, Cheryl Farren Tkacs

Electronic Theses and Dissertations

The purpose of this study was to investigate how prior music learning experience relates to learning with multimedia resources in non-music disciplines. Specifically, whether years of music learning experience, type of music learning experience, or type of multimedia were associated with task scores and task duration in a non-music discipline. The study revealed the transferable benefits of music learning experience to learning outcomes in other disciplines. Encouraging music studies as part of the base curriculum is thus strongly encouraged. However, as years of music learning and the presence or absence of segmenting in multimedia learning resources were not found to …

Examining The Impact Of The Covid-19 Pandemic On Violent Crime In The City Of Pittsburgh, Brittany Urban

Electronic Theses and Dissertations

This descriptive analysis is based primarily upon …

Advancing Fluorescent Contrast Agent Recovery Methods For Surgical Guidance Applications, Brook Kennedy Byrd

Dartmouth College Ph.D Dissertations

Fluorescence-guided surgery (FGS) utilizes fluorescent contrast agents and specialized optical instruments to assist surgeons in intraoperatively identifying tissue-specific characteristics, such as perfusion, malignancy, and molecular function. In doing so, FGS represents a powerful surgical navigation tool for solving clinical challenges not easily addressed by other conventional imaging methods. With growing translational efforts, major hurdles within the FGS field include: insufficient tools for understanding contrast agent uptake behaviors, the inability to image tissue beyond a couple millimeters, and lastly, performance limitations of currently-approved contrast agents in accurately and rapidly labeling disease. The developments presented within this thesis aim to address such …

Powers And The Metaphysics Of Fundamentality, Benjamin Cook

Dissertations - ALL

In this dissertation, I address the question of whether ground, the relation that obtains between entities e1...en and a further entity e when e ontologically depends on, and is metaphysically explained by, e1...en, should be understood causally and, if so, whether this has any substantive implications. I answer both in the affirmative. I argue that ground and causation are similar enough to motivate characterizing ground as a special kind of causation, and that this can be done if we adopt a powers-theoretic account of causation. Moreover, I argue that the resultant view of ground, what I call “powerful, existential causation,” …

The Impact Of Antecedent Physical Exercises On Increasing On-Task Behaviors And Decreasing Restricted And Repetitive Behaviors In Elementary Students With High Functioning Autism Spectrum Disorder In Saudi Arabia, Shadi Albadawi

Electronic Theses and Dissertations

Physical exercises (PEs) are one of the most used approaches by researchers to treat restricted and repetitive behaviors (RRBs) and enhance on-task behaviors in students with high-functioning Autism spectrum disorders (ASD). Although PEs is recognized as Evidence-based Practices (EBPs) for students with ASD in the United States of America (USA) that are based on moderate evidence, it is important to conduct more empirical studies to explore its effects on individuals with ASD from different populations in the KSA. The current study used a single-subject, multiple baseline design across subjects to examine the effect of antecedent structured physical exercises (teaching soccer …

Estimating Vehicle Infrastructure: Downtown Albuquerque, New Mexico, Zachery Phillip Baiamonte

Architecture and Planning ETDs

Cities have little knowledge about their parking infrastructure despite clear evidence that abundant parking has environmental, economic, and transportation consequences. The objective of this thesis is to illustrate the need to accurately estimate the area dedicated to vehicle infrastructure (parking lots and streets) within urban areas. I focused on a method that estimated the vehicle infrastructure area within the Downtown Core of Albuquerque, New Mexico, by cross-referencing geospatial cadastral data with minimum parking requirements. Three parking space types were identified: 1) parking in structures; 2) surface parking (parking lots and residential driveways); and 3) on-street parking. To illustrate the need …

Utilizing Remote Sensing Technology To Relocate Lubra Village And Visualize Flood Damages, Ronan Wallace

Mathematics, Statistics, and Computer Science Honors Projects

As weather patterns change worldwide, isolated communities impacted by climate change go unnoticed and we need community and habitat-conscious solutions. In Himalayan Mustang, Nepal, indigenous Lubra village faces threats of increasing flash flooding. After every flood, residual concrete-like sediment hardens across the riverbed, causing the riverbed elevation to rise. As elevation increases, sediment encroaches on Lubra’s agricultural fields and homes, magnifying flood vulnerability. In the last monsoon season alone, the village witnessed floods swallowing several fields and damaging two homes. One solution considers relocating the village to a new location entirely. However, relocation poses a challenging task, as eight centuries …

Coordination Chemistry Of Uranyl Ions With Surface-Immobilized Peptides: An Xps Study, Esha Mishra, Cody M. Schultz, Rebecca Lai, Peter A. Dowben

Department of Physics and Astronomy: Faculty Publications

The coordination chemistry of uranyl ions with surface immobilized peptides was studied using X-ray photoemission spectroscopy (XPS). All the peptides in the study were modified using a six-carbon alkanethiol as a linker on a gold substrate with methylene blue as the redox label. The X-ray photoemission spectra reveal that each modified peptide interacts differently with the uranyl ion. For all the modified peptides, the XPS spectra were taken in both the absence and presence of the uranium, and their comparison reveals that the interaction depends on the chemical group present in the peptides. The XPS results show that, among all …

Sunflower Oil-Based Polyol In Flame-Retardant Rigid Polyurethane Foams, Magdalene Asare

Electronic Theses & Dissertations

The current shift from solely depending on petroleum sources to seeking renewable alternatives is due to their fast depletion, spike in prices, and the need to reduce our carbon footprint. For instance, the polyurethane industry currently calls for renewable and less toxic polyols and isocyanates for their synthesis over the traditionally used ones. To tackle an aspect of this matter, this work investigates the generation of polyol from sunflower oil, and further probes their use in rigid foams, one of the widely utilized polyurethanes. Epoxidation and ring-opening reactions were used to convert the sunflower oil into a more reactive form, …

Analyzing The Effects Of Climate Impacts In El Salvador And How They Influence Pollution, Ecosystems And Communities, Veronica Norio-Tomasino

Master's Projects and Capstones

Due to projections of rising temperatures and increased frequency and severity of extreme weather events, the rate at which climate change is impacting nations is devastating. However, developing countries and vulnerable communities are not the primary contributors to climate change, but they are at a greater risk for climate impacts by industrialized nations. As a result of increased human activity, developing nations such as El Salvador are particularly susceptible to climate-related events. Deforestation, water pollution, and human health risks are some activities that have contributed to El Salvador's vulnerability to climate change, drastically affecting rural communities suffering from multidimensional poverty. …

Evaluating Equity In Transportation Greenhouse Gas Emission Reduction Strategies In Local Climate Action Planning In Oakland, California, Eliza J. Kane

Master's Projects and Capstones

Emissions from California’s transportation sector contribute to global climate change and impact local air quality and public health. Forty-one percent of California’s greenhouse gas emissions in 2019 were from transportation. Transportation emissions are also a source of many health-harming air pollutants such as carbon monoxide, volatile organic compounds, and particulate matter. Disadvantaged communities in California experience disproportionate impacts from transportation emissions and suffer worse health effects, including higher incidences of asthma, cardiovascular disease, and premature death. Cities have led the way in policymaking to mitigate and adapt to climate change, including creating Climate Action Plans (CAPs) to propose strategies to …

Tuberculosis (TB) is one of the leading causes of mortality in people living with HIV (PLHIV) and contributes to up to a third of deaths in this population. The World Health Organization guidelines aim to target early detection and treatment of TB among PLHIV, particularly in high-prevalence and low-resource settings. Prevention plays a key role in the fight against TB among PLHIV. This review explores TB screening tools available for PLHIV, including symptom-based screening, chest radiography, tuberculin skin tests, interferon gamma release assays, and serum biomarkers. We then review TB Preventive Treatment (TPT), shown to reduce the progression to active …

Delineating Differences In How Us High Schools Are Racialized, Dara Shifrer, C. J. Appleton

Sociology Faculty Publications and Presentations

Schools’ overt or explicit practices are a dominant lens through which education researchers and policymakers attempt to understand how schools are racially inequitable. Yet, Lewis and Diamond argue that contemporary racial inequalities are largely sustained through implicit factors, like institutional practices and structural inequalities. Ray’s framework on racialized organizations similarly outlines how our racialized sociopolitical structure becomes embedded in organizations, legitimating and perpetuating the racialized hierarchy. We apply illustrative cluster analysis techniques to rich data on schools, teachers, and students from the nationally representative High School Longitudinal Study of 2009 to find that structural inequities (e.g., student body, sector, average …

Socio‑Economic Inequalities In Minimum Dietary Diversity Among Bangladeshi Children Aged 6–23 Months: A Decomposition Analysis, Satyajit Kundu, Pranta Das, Ashfikur Rahman, Hasan Al Banna, Kaniz Fatema, Akhtarul Islam, Shobhit Srivastava, T. Muhammad, Rakhi Dey, Ahmed Hossain

Department of Statistics: Faculty Publications

This study aimed to measure the socio-economic inequalities in having minimum dietary diversity (MDD) among Bangladeshi children aged 6–23 months as well as to determine the factors that potentially contribute to the inequity. The Bangladesh Demographic and Health Survey (BDHS) 2017–2018 data were used in this study. A sample of 2405 (weighted) children aged 6–23 months was included. The overall weighted prevalence of MDD was 37.47%. The concentration index (CIX) value for inequalities in MDD due to wealth status was positive and the concentration curve lay below the line of equality (CIX: 0.1211, p < 0.001), where 49.47% inequality was contributed by wealth status, 25.06% contributed by the education level of mother, and 20.41% contributed by the number of ante-natal care (ANC) visits. Similarly, the CIX value due to the education level of mothers was also positive and the concentration curve lay below the line of equality (CIX: 0.1341, p < 0.001), where 52.68% inequality was contributed by the education level of mother, 18.07% contributed by wealth status, and 14.69% contributed by the number of ANC visits. MDD was higher among higher socioeconomic status (SES) groups. Appropriate intervention design should prioritize minimizing socioeconomic inequities in MDD, especially targeting the contributing factors of these inequities.
