The Uncertain Future Of Landscapes Subjected To Mountaintop Removal Mining, Samuel James Bower

Graduate Theses, Dissertations, and Problem Reports (ETD)

Increased erosion following human land disturbance is a global issue for ecosystem health and land management. Mountaintop removal (MTR) mining – a type of surface mining predominately found in the Central Appalachian Coalfields region – is one of the most significant examples of human perturbation to a natural landscape. A post-MTR landscape, when compared to its natural state, has significantly different erosive potential due to the rearrangement of topography from mining and reclamation practices. Removal of vegetation and alterations to soil further influence erosion by raising the effective erodibility of substrate subjected to MTR. We quantify the changes in erosion …

The Eruption Of Disruption: The Manifestation Of Disrupting Whiteness In Secondary Social Studies In Appalachia, Elizabeth Disalvo Osborne

Graduate Theses, Dissertations, and Problem Reports (ETD)

This phenomenological dissertation explores the lived experiences of secondary social studies educators situated in the Appalachian region. Hermeneutic phenomenology was used as a philosophical and methodological approach to gather insights into this phenomenon. Interviews were conducted with three educators to capture their experiences from their childhoods, to their teaching careers, and into their current personal lives. These experiences were analyzed using a Whole-Part-Whole process to understand how they came to disrupt whiteness, the ways they did so, and their understanding of the impact disrupting whiteness for creating learning environments, developing curriculum and making instructional decisions. The findings revealed how these …

Toward A Reconceptualization Of Gentrification: Assessing Neighborhood Variation By Socioeconomic And Economic Processes, Annette M. Mackay

Graduate Theses, Dissertations, and Problem Reports (ETD)

The core conceptualization of gentrification is social class ascension. Researchers and the public have often disagreed about how, when, where, and why gentrification occurs. When there is agreement, researchers often add specifications, such as displacement, that further confuse the concept. Reasons for the confusion include non-integrating theoretical dimensions, methods that assume independent effects, and the context of place. The objective of this study is to conceptualize gentrification in a case study city using two key dimensions, socioeconomic and economic processes, in a spatial context. Using principal component analysis to identify the latent constructs that account for change in Pittsburgh, PA, …

Behrang Bidadian

In recent decades, urban areas have witnessed a rise in floods which have posed a significant threat to human life and wealth, due to the effects of global warming. While researchers have conducted extensive studies on natural disaster risk focusing on components such as hazard, exposure, and vulnerability, certain aspects of this field have remained inadequately understood. To fulfill this need, the primary objective of this dissertation was to enhance our understanding of flood risk in urban areas, considering it a crucial example of natural …

Spatial Variability In Above Ground Carbon Within An Appalachian Forest, Megan A. Ponczek

Graduate Theses, Dissertations, and Problem Reports (ETD)

Forests have long been recognized for their provision of air and water quality ecosystem services to society; but more recently, they have become valuable to the carbon credit markets used as a tool for mitigating climate change. Quantifying above ground carbon storage in forest ecosystems is essential for these carbon credit markets and can also provide insight into factors that control the spatial distribution of carbon in forests. The goal of this study is to assess the degree to which three factors: topography, tree species, and legacies of logging, impact the spatial variability in above ground carbon within a 400x500m …

Bedrock Channel Geometry: Meter To Micron Scale Controls On Fluvial Incision, Nicholas J. Colaianne

Graduate Theses, Dissertations, and Problem Reports (ETD)

The relative resistance of various rock types to incisional processes vary widely and the properties governing bedrock erodibility are poorly understood. Lithologic properties influencing erodibility are the culmination of a rock’s depositional, diagenetic, and exhumation processes. Difficulty identifying a convenient physical proxy for erodibility suggests examining evidence of these processes holistically may offer insight into the role of each in setting a rock’s resistance to incisional forces. In this study we use measured channel geometries along a short stretch of the Dry Fork, WV hosting three distinct lithologic settings to infer relative erodibility against measured and observed fluvial, lithologic, and …

Development Of A Hydrometallurgical Process For The Extraction Of Cobalt, Manganese, And Nickel From Acid Mine Drainage Treatment Byproduct, Alejandro Agudelo Mira

Graduate Theses, Dissertations, and Problem Reports (ETD)

Critical minerals (CMs) are defined as crucial elements for the country's economy due to the development of new cutting-edge applications and the risk of an eventual disruption in their supply chain. The unique chemical and physical properties of the CMs have made these elements decisive in the growth of industries such as telecommunications, army, medicine, Aerospace, etc. In 2022, the US Geological Survey established a list of 50 CMs, including manganese, cobalt, nickel, aluminum, magnesium, and others. Of the total of CMs, 26 are 100% imported from outside the United States (Venditti, 2022).

Relationships Between Geochemistry, Carbon Content, And Grain Size In Clastic Cave Sediments, Rebekah Rose Nicholas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Understanding geochemical and physical properties of cave sediment gives insight to sediment characterization and carbon storage in the cave system. Previous work on clastic sediments largely encompasses physical properties, neglecting the importance of geochemical parameters on sediment deposition.

This study reports physical and chemical properties of sediment cores from three caves: two caves in Puerto Rico and one cave in Virginia. A total of 25 cores were used in this study; 6 of these cores were new and collected in 2022 from Butler Cave (BTC) in Virginia to focus on the effects of water level. Core samples were analyzed for …

Abundance-Habitat Relationships And Aquatic-Terrestrial Habitat Selection Patterns For Wood Turtles (Glyptemys Insculpta) In The Upper Midwest, Jena Marie Staggs

Graduate Theses, Dissertations, and Problem Reports (ETD)

Due to range-wide population declines, wood turtles (Glyptemys insculpta) are under review for federal listing under the United States Endangered Species Act. Understanding how habitat associations and environmental conditions influence population dynamics and spatiotemporal activity patterns is fundamental for designing effective management strategies. Previous work on wood turtle abundance-habitat relationships focused on broad-scale habitat relationships in northeastern North America. However, regional differences in climate, habitat conditions, and land use patterns limit their applicability to much of the wood turtle’s Upper Midwest distribution. Much of our understanding of wood turtle activity patterns is based on radiotelemetry studies, which are biased towards …

Assessing Spurious Correlations In Big Search Data, Jesse T. Richman, Ryan J. Roberts

Political Science & Geography Faculty Publications

Big search data offers the opportunity to identify new and potentially real-time measures and predictors of important political, geographic, social, cultural, economic, and epidemiological phenomena, measures that might serve an important role as leading indicators in forecasts and nowcasts. However, it also presents vast new risks that scientists or the public will identify meaningless and totally spurious ‘relationships’ between variables. This study is the first to quantify that risk in the context of search data. We find that spurious correlations arise at exceptionally high frequencies among probability distributions examined for random variables based upon gamma (1, 1) and Gaussian random …

This chapter assesses the state of the technology, interdisciplinary science and engineering literature, and presents case studies from the Chesapeake Bay, Virginia, and coastal North Carolina, USA, that demonstrate new insights into coastal geomorphic processes and applications to managing complex and dynamic estuarine shorelines. These technologies enhance the …

A Model Of Build Back Better Utilization: Long-Term Recovery Groups And Post-Disaster Housing Recovery, Eduardo Landaeta, Jesse Richman

Political Science & Geography Faculty Publications

Housing recovery, especially for vulnerable populations, can be a challenging process. Questions regarding whether to rebuild damaged housing and whether to restore it to its previous state or to build back better must be answered. In the United States, Long-Term Recovery Groups (LTRGs) play a crucial role in channeling assistance to vulnerable community members as they embark on housing recovery. However, the experiences of LTRGs have been understudied. To address this gap, the study utilizes interviews with a diverse range of LTRG members and develops an agent-based model following the Overview, Design concepts, and Details (ODD) protocol.

Comparing Agency Costs In Contract Production: Private Equity M&A Versus Corporate And Sovereign Bonds, Stephen J. Choi, Mitu Gulati, Robert E. Scott

Faculty Scholarship

Different areas of transactional practice, such as M&A or high-yield bonds and sovereign bonds, vary in terms of the degree to which they are afflicted by agency problems. In some areas, clients are actively involved in deal making, and in others they are not present until well after the deal is done. If vulnerability to agency problems differs, and these agency problems impact the quality of contract production, one would expect those differences to appear when comparing contract production across practice areas. This Article compares one feature of contract production — the problems of encrusted and sticky boiler-plate — across …

The Gravity Of Legal Diffusion, Anu Bradford, Adam S. Chilton, Katerina Linos

Faculty Scholarship

A persistent empirical finding is that bilateral trade between two countries is proportional to the size of their economies and inversely proportional to their geographic distance. We hypothesize that a similar pattern is likely to hold for the diffusion of laws. We specifically argue that countries’ propensity to update their laws to converge with the leading regulator in a given policy area is likely to be proportional to the size of their economies and inversely proportional to their geographic distance. We then empirically test this theory in the area of antitrust and assess countries’ convergence to the world’s leading antitrust …

Nannies And Public Space: Reproductive Labor In Richmond, Va, Hannah D. Woehrle

Theses and Dissertations

In the realm of urban planning, the gendered and spatial dynamics of childcare as a field of labor have been historically overlooked. This thesis addresses this gap by examining the geographies shaped by nannies in Richmond, VA, and their implications for urban planning in the context of the evolving neoliberal "new" economy. Existing research focuses on the geographies of children and burgeoning sectors of gig work in the neoliberal city. This study positions itself at the intersection of these areas, focusing on nannies as long standing gig workers within the childcare network, uniquely positioned to be affected by economic transitions. …

Investigation Of Small Mammal Species Richness, Abundance, And Genetic Population Structure On And Around The Eastern Washington University Prairie Restoration Site, Sarah Deshazer

EWU Masters Thesis Collection

Small mammals are an ecologically important component of every landscape on Earth. They are a food source for higher trophic level animals, disperse plant seed and mycorrhizal fungi spore, engineer the landscape through burrowing and foraging activities, and alter plant community composition through selective predation of seed and grain. Studies have shown that small mammals may help facilitate the transition between successive stages in prairie restoration. Eastern Washington University has dedicated 120 acres of campus land to restoration of native prairie habitat. Small mammals can play both a positive and a negative role in restoration, therefore it is important to …

Transmission Competence Of B. Burgdorferi Infected Ixodes Ticks And Development Of An Ospc-Based Lyme Disease Vaccine, Samanta Kamalika

Theses and Dissertations (ETD)

Introduction. Lyme disease, otherwise called Lyme borreliosis, is a vector-borne infectious disease caused by the spirochete Borrelia burgdorferi (Bb). Studying the increase in overall Lyme disease incidence requires understanding the role of the vector Ixodes scapularis (I. scapularis) as the agent that carries the spirochete which is important to limit the occurrence of Lyme disease. Once we understand the vector-pathogen response, it also becomes important to determine the remedies for Lyme disease. Lyme disease can be treated with antibiotics if detected early, but the major obstacle lies in the early detection process. Therefore, it is important to investigate alternative preventive …

Sustainable Urban Development Approach In Residential Building, Ayah Mohamed Ramadhan, Ahmed Noor Eldin

Mansoura Engineering Journal

Globally, Due to its damaging effects on energy, consumption, health, wellbeing, and air pollution, the urban warming phenomenon is gaining worldwide awareness from scientists to planners and legislators. In order to achieve the equation and reach an energy-saving urbanization, we must reconcile with the environment by providing a sustainable urban design that works to rationalize energy and reduce the depletion of resources and reach a sustainable urban environment by providing thermal comfort requirements. In order to attain three key characteristics that are related to one another—thermal comfort, reduced energy consumption, and reduced CO2 emissions—the study will examine a variety of …

2020-Current year OA Pubs

BACKGROUND: Diarrheagenic Escherichia coli (DEC) are common pathogens infecting children during their growth and development. Determining the epidemiology and the impact of DEC on child anthropometric measures informs prioritization of prevention efforts. These relationships were evaluated in a novel setting, Cap-Haitien, Haiti.

METHODS: We performed pre-specified secondary analysis of a case-control study of community-dwelling children, 6-36 months of age, enrolled 96 cases with diarrhea and 99 asymptomatic controls. Assessments were performed at enrollment and one month later at follow-up. Established endpoint PCR methodologies targeted DEC gDNA isolated from fecal swabs. The association between DEC and anthropometric z-scores at enrollment was …

An Empirical Analysis Of The Link Between Built Environment And Safety In Chicago’S Transit Station Areas, Ahoura Zandiatashbar, Agustina Laurito

Faculty Research, Scholarly, and Creative Activity

Problem, research strategy, and findings: Considering that safety is a key environmental factor that promotes health, understanding the relationship between built environment features around transit station areas and crime may shed light on how to foster healthy communities. Yet, there is limited work that has examined how the combination of different built environment features around transit correlate with different crimes. We addressed this issue in this study using data from Chicago (IL). First, we used cluster analysis to classify stations in Chicago in a spectrum from transit-oriented development (TOD) to transit-adjacent development (TAD) categories depending on their built environment characteristics: …

Unravelling And Understanding Local Perceptions Of Water Quality In The Santa Basin, Peru, Sally Rangecroft, Dextre R Maria, Isabel Richter, Bueno Cv Grados, Claire Kelly, Cecilia Turin, Beatriz Fuentealba, Hernandez M Camacho, Sergio Morera, John Martin, Adam Guy, Caroline Clason

School of Geography, Earth and Environmental Sciences

Water quality is an integral part of water security. Measuring the physico-chemical indicators for water quality can provide an objective picture of water health, but it does not provide information on lived experiences related to water quality, expectations of water resources, nor how the quality of water affects its usage. Perceptual information and traditional ecological knowledge on water quality can help to understand interactions between water and people, and thereby support locally appropriate sustainable water resource strategies. Accordingly, our project sought to collect and synthesise insights from local perspectives on water quality in the upper Santa River basin, Peru, a …
