Spatial Variability Of Heat Mortality Rate Relationships In Arizona At Primary Care Area Level, Ria Mukherjee

Theses and Dissertations

Heat Mortality Rates (HMR) in Arizona (AZ) are one of the highest in all of US. The HMR association with environmental, socioeconomic, demographic, and occupational factors has been widely investigated to inform mitigative policy. This study employed linear and spatial models- Ordinary Least Square (OLS), Geographically Weighted Regression (GWR) and multiscale Geographically Weighted Regression (MGWR), across AZ at Primary Care Area (PCAr) level to identify important spatial trends in HMR relationship. Results indicated a significant global association between heat mortality and environmental variables and the elderly population aged 65 and older. In contrast, the working age group between 54 and …

Our investigation sheds light on the nuanced tensions inherent in employing data science for social justice. Rooted in situated perspectives of learning and consequential learning, our study employs an instrumental case-study methodology and analysis techniques from interaction and conversation analysis. Collaborating with three undergraduate students and an urban farm, the students used data science practices to highlight inequities surrounding food justice and access to food. …

Hybrid Geographies And Nature In The City: A Tale Of Two Greenspaces In Louisville, Ky., Rebecca Dixon

Electronic Theses and Dissertations

Many conservation initiatives position nature and the urban as opposing constructions, which means the possibilities where cities can work with nature are often overlooked. This study uses the lens of relational geographies to examine nature in the city by comparing two greenspaces in the Beargrass Creek watershed in Louisville, Kentucky: Waterfront Botanical Gardens and the Louisville Nature Center. The two organizations are compared by using a combination of content analysis, discourse analysis, and GIS flood analysis methods to determine how their geographical location and history affect the ways in which the dynamic between nature and culture is reproduced. Results show …

Tree Rings And The Broader Ocean-Atmospheric Circulation In The Highland Himalayas, Sanjaya Bhandari

All-Inclusive List of Electronic Theses and Dissertations

Climate change has altered tree-growth patterns and resulted in higher sea-surface temperatures across the planet. The Himalayan biome is one of the most vulnerable areas in the world to climate change because it has caused changes in forests’ growth and glaciers’ retreat. Dendrochronology has been used to understand the impact of climate change on tree growth and for climate reconstruction. In this dissertation, I discuss the growth of trees in the highlands of the eastern, central, and western Himalayas for the last 500 years and relate these patterns to the present global warming scenario and broad-scale climate modes. I reconstructed …

Developing Guidance For The Use Of Floating Treatment Wetlands In Brackish Stormwater Ponds, Clare Escamilla

All Dissertations

Stormwater ponds are commonly used as a flood control strategy, particularly in coastal developments. Many coastal stormwater ponds are impaired with high nutrient levels that can lead to algal blooms, impacting the water quality of the pond and surrounding ecosystem. Floating treatment wetlands (FTWs) are one potential strategy that can be implemented in stormwater ponds to reduce high nutrient concentrations, however limited research has been done in brackish waterbodies. To determine the suitability of using FTWs in brackish stormwater ponds this research focused on (1) coastal resident perceptions of FTWs and (2) plants that can be utilized in FTWs deployed …

Identifying Topographic Influences Of Landcover Change In A Subarctic Watershed, Mason Bull

Boise State University Theses and Dissertations

Increased temperatures over the last 40 years have globally promoted a loss of ice and increase of plant cover and density, known as greening. Greening is seen more in arctic and alpine environments than elsewhere, and current literature states that new growth consists of low-lying tundra plants, as well as encroaching shrub communities into previously uninhabited rocky slopes. However, our understanding of greening processes and extent is potentially biased by study strategies. Many vegetation studies take place at either the small plot or arctic regional scale, and do not encapsulate the intricacies of watershed scale processes on greening. This study …

Technoscientific Imaging And The Territorialization Of Ocean Depth, João Afonso Baptista, Pedro Figueiredo Neto, Irus Braverman, Philip Steinberg, Gabriella Palermo, Stefan Helmreich, Melody Jue, John Childs

Journal Articles

Once the last unclaimed solid expanse on Earth, the ocean floor has become one of the most contested spaces in contemporary geopolitics. The data-imagery produced by technoscience serves as the ultimate tool for nations asserting sovereignty in this territorial race. This symposium gathers diverse perspectives on the ongoing expansionist drive on the seabed, drawing inspiration from Abissal——a film-article featuring the Portuguese modern odyssey on the ocean floor that serves as the symposium’s centerpiece. Aligned with modern ocean law, technoscience strives to render ocean depth visible to politics and territorializable for coastal states. However, the submerged prolongations and divisions it proffers …

Mathematics, Physics, and Computer Science Faculty Articles and Research

This study presents a GIS-based multi-criteria decision-making framework to assess climate-induced migration risk along the West African coast. We developed a comprehensive risk index that integrates environmental hazards such as flood frequency and socio-economic vulnerability indicators, including poverty levels, population density, and adaptive capacity. By utilizing datasets such as the Geocoded Disasters (GDIS) dataset, Social Vulnerability Index (SVI), Poverty and Adaptive Capacity Index (PACI), and the Population Exposure Index (PEI), the study identifies regions most susceptible to displacement. Results reveal that areas like Benin’s Abomey-Calavi, Cotonou, and Akpo-Misserete are especially vulnerable due to high disaster frequency, substantial population exposure, and …

Forgotten Landscapes: Using Original Land Surveys To Understand The Historic Distribution Of Cane Brakes In Wayne County, Ms, Chad Mackness

Master's Theses

This study investigates the historical presence and ecological significance of Arundinaria gigantea (giant cane) in 1810, Wayne County, Mississippi, using original survey documents. These records provide rare quantitative insights into the distribution of cane brakes, revealing that A. gigantea possibly represented up to 44% of the surveyed landscape, likely second only to Pinus palustris (longleaf pine).

This research involved digitizing historical surveyors' notes, transcribing them into a structured format, and extracting spatial data for GIS analysis. The methodology developed for this research can be used to ensure the preservation and usability of these historical documents for future research. …

The Arctic environment in 2024 continued on a trajectory that has put it in a state far different from that of the twentieth century. Ongoing accumulation of greenhouse gases in the atmosphere continues to quickly warm the Arctic, resulting in rapid changes in the cryosphere that are driving cascading impacts to climate, ecological, and societal systems.

A New Approach To Probabilistic County Population Forecasting With An Example Application To West Texas, David Swanson, Jeff Tayman, Mike Cline

Publications, Reports and Presentations

This paper shows how measures of uncertainty can be applied to existing subnational population forecasts using the 107 counties that make up West Texas as a case study. The measures of forecast uncertainty are relatively easy to calculate and meet several important criteria routinely applied by state and local demographers. We also report the results of two independent comparisons supporting the argument that our approach is valid. The paper concludes it is well-suited for developing probabilistic population forecasts in the United States and elsewhere.

Rhetorics Of Encounter: Toward A Biocentric Theory Of Discourse, Matthew D. Whitaker

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Encounters with more-than-human identities are transformative moments that stand to affect dispositional and bodily change in individuals. From close brushes with wild animals in National Parks to everyday interactions with local ecologies, encounters invite us to feel and think differently about the nature of our realities. In Rhetorics of Encounter: Toward a Biocentric Theory of Discourse, I draw from interdisciplinary perspectives to disrupt the idea of rhetoric as a representational medium, arguing that rhetoric occurs not just through textual exchanges of words and symbols, but through embodied moments of contact with other responsive beings. Invoking George Kennedy’s theory …

Constructing A State: Canals And The Transformation Of The Economy, Politics, And Finance In Nineteenth-Century New York, Youwei Xing

All Dissertations

This dissertation consists of three essays in economic history, unified by a focus on one of America's earliest transportation infrastructures, the canal system, in nineteenth-century New York. Each chapter explores a different aspect of the state's transformation: its economy, politics, and finance, each of which helped construct New York as the Empire State.

The first chapter studies the economic impact of canals on economic modernization from three aspects: sectoral transition, urbanization, and banking development. Contrary to much of the modern literature finds transportation infrastructure leads to decentralization, I find the opposite-evidence of centralization. Specially: (1) canal towns experienced a transition …

Inspired by SMU City Dialogues, I explore here how cities can bounce back, …

A Multi-Scale Approach For Integrating Species Distribution Models With Landscape Connectivity To Identify Critical Linkage Zones For African Savanna Elephants (Loxodonta Africana), Lei Song, Amy E. Frazier, Anna Bond Estes, Lyndon Despard Estes

Geography

The populations of African savanna elephants have declined by an estimated 60 % since the 1970s, which can be attributed to a mixture of poaching and habitat loss. Human activities and environmental changes have caused unprecedented loss and fragmentation of elephant natural habitats, resulting in the isolation of elephant populations. Preserving habitat connectivity is thus increasingly important to conserve remaining elephants' populations and maintain ecological functions. A major challenge in large-scale connectivity modeling is data availability constraints. To tackle this issue, we developed an integrated modeling approach that leverages multiple, publicly available occurrence datasets, which vary in format and quality, …
