Increasing Access To Rural Resources: A Spatial Exploration Of The Social Implications Of Mobility In Appalachian Kentucky., Anna Morris

College of Arts & Sciences Senior Theses

Mobility and accessibility are key predictors in the way that people navigate their communities. However, many rural areas lack holistic transportation systems that support the needs of a diverse range of users. As a result, rural residents, especially rural non-drivers, often face barriers to equitable mobility and access to necessary resources, like healthcare. This study examines the role that mobility plays in facilitating access to healthcare facilities for driving and non-driving populations in Appalachian Kentucky. The study pairs the Enhanced 2-Step Floating Catchment Area method with a demographic index to evaluate mobility equity through spatial accessibility to primary care facilities. …

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.

Using spatial analysis and multiple regression techniques, the study examines how these factors contribute to variations in school enrollment within the selected MSAs. The results reveal that income level and racial composition significantly affect enrollment patterns while other factors such as urbanicity had minimal impact. …

Pre-Columbian Soil Management, Settlement, And Land Use In Amazonia: Insights Using Micro-Regional Predictive Modelling In Gurupá, Brazil., Lauren Zacks

Electronic Theses and Dissertations

The results of a micro-regional predictive model of terra preta sites in the municipality of Gurupá are presented here. A Maximum Entropy approach was selected and modified to fit a presence-background model, rather than a presence-absence model typical of binary classifications. 13 known terra preta sites were used as input samples for the relative suitability model, with explanatory variables in the respective categories of topography, hydrology, soil type and vegetation index. A 30m spatial resolution DEM served as the basis for the former two categories, while additional TauDEM analysis was performed for the hydrology category. A Sentinel-2A mosaicked quarterly composite …

Understanding Land Uses And Their Manifestations Across The Rural-Urban Continua Of Rangpu, Bangladesh And Louisville, Kentucky., Md Jakirul Islam Jony Prothan

Urban fabrics paved by concretes and asphalts absorbs solar radiation during solar peak then radiates heat after sundown. This study investigates temperature distribution data related to the UHI effect on the Belknap campus at the University of Louisville, which represents a small aerial sample of the Louisville metropolitan UHI effect. The objective of this study is to measure the reflectivity of ground surfaces and air temperatures on the Belknap campus during …

Anthropogenic Landscapes Of Amazonia : A Spatial Analysis Of Landscape Modification And Settlement Organization At Macurany, Brazil., M. Grace Ellis

Electronic Theses and Dissertations

Anthropogenic landscapes are the product of complex human-environment processes that form distinct features in the landscape, which materially preserve and reflect human behavior. Anthropogenic landscapes in Amazonia likely date back to human colonization of the region around 16,000 BP. Since colonization, humans have been marking, modifying, managing, and engineering the landscape resulting in a mosaic of anthropogenic landscape features across Amazonia. The diversity of ancient landscapes documented in Amazonia reflects the cultural heterogeneity that existed in the past. This research explores the complex human-environmental processes that form distinct, identifiable, lasting features on the landscape and what these features can illuminate …

Dixie Tornadoes : A Spatial Analysis Of Tornado Risk In The U.S. South., Joshua L. Sherretz

Electronic Theses and Dissertations

Throughout the years tornados were a feared and respected phenomenon. This phenomenon was traditionally associated with the high plains of the United States for very good reason. More tornados occur in the American high plains than anywhere else in the world, hence the term: Tornado Alley. However, the American Deep South was and remains prone to many tornados too. So much so that parts of the Deep South were and still are referred to as Dixie Alley. The major focus of this study was how the two areas compared as far as risk is concerned.

This study used both geographic …

Electronic Theses and Dissertations

Using pre-post survey data collected from 209 randomly selected African American people from the population of former residents of Clarksdale and Sheppard Square public housing areas, this study explores the relationship between individual characteristics and colorectal cancer screening behavior, measured by the uptake of the Fecal Immunochemical Test (FIT) and by prior colorectal screening, while controlling for neighborhood factors and geographic proximity to healthcare facilities. This particular public housing population is of interest because of their relocation from the downtown area, where healthcare facilities are within walking distances, to other public housing units either in large apartment complexes or scattered …

Global Population Distributions And The Environment : Discerning Observed Global And Regional Patterns., Jeremiah J. Nieves

Electronic Theses and Dissertations

Between 1990 to 2015, numerous groups used ancillary data about the environment surrounding populations to more accurately map global populations from standard census data. No comprehensive study has been undertaken to characterize the observed relationships between population density and ancillary data. Better understanding these relationships may produce more accurate population maps, focus resources on new datasets with a high probability of modelling importance, and lead to expanded end-user applications. This study examined these relationships by extracting variable importances from 36 independently run, country-specific population models from the WorldPop project’s population data. Covariate data describing urban/suburban extents were found to be …
