A Geographical Analysis Of Gentrification And The Changing Foodscape In Seattle 2010-2017, Alice Tiffany, Michele Romolini

Honors Thesis

Anguelovski defines food privilege as “the exclusive access to desirable ‘natural’ and fresh food thanks to one’s economic, cultural, and political power” (Anguelovski 2015a). Previous studies have demonstrated that access to fresh, healthy, affordable food is correlated with socioeconomic status (LA Food Policy Council 2017; Walker et al. 2010; Alkon & Agyeman 2011; Raja et al. 2008). However, as is being increasingly noted, the introduction of environmental amenities, such as farmers markets and community gardens, can have unintended consequences and trigger environmental gentrification (Kern 2015; Pearsall 2010; Eckerd 2011; Curran & Hamilton 2012; Wolch et al. 2014; Alkon & Cadji …

Potable Water Leakage Prediction And Detection Using Geospatial Analysis, Jacob Tittle

Electronic Theses and Dissertations

Due to increasing water treatment costs and conservation needs, traditional water loss analysis and acoustic leak detection methods are becoming heavily scrutinized by water utilities. This study explores water loss in Johnson City, Tennessee and how geospatial data analysis techniques improve water loss mitigation. This project uses sample water system pressure data and ordinary kriging spatial interpolation methods to identify leakage areas for further investigation. Analysis of existing geographic information system (GIS) water utility datasets with interpolated hydraulic grade values at sample water pressure points produce manageable survey areas that pinpoint areas with possible water leakage. Field detection methods, including …

Measurement Of Changes In Forest Fragmentation Caused By Road Construction Between 2000 And 2014 Using Gis In St. Johns County, Florida, Ahmet Karatas

USF Tampa Graduate Theses and Dissertations

Forests play a crucial role in maintaining the natural balance. They have essential features and structures used in the protection of flora and fauna. Human activities such as road construction disrupt ecosystems and negatively impact natural habitats. Roads cause forest fragmentation, and as a result of this, fragmentation has various negative effects on the natural habitat. These effects lead to loss of biological diversity, road mortality, habitat loss, fragmentation, and air pollution. The major goal of this study was to analyze changes in forest area, forest fragmentation, and forest road impacts using GIS for St. Johns County, Florida, between the …

Mapping Time-Space Brickfield Development Dynamics In Peri-Urban Area Of Dhaka, Bangladesh, Mohammad Mehedy Hassan, Levente Juhasz, Jane Southworth

GIS Center

Due to the high demand for cheap construction materials, clay-made brick manufacturing has become a thriving industry in Bangladesh, with manufacturing kilns heavily concentrated in the peripheries of larger cities and towns. These manufacturing sites, known as brickfields, operate using centuries-old technologies which expel dust, ash, black smoke and other pollutants into the atmosphere. This in turn impacts the air quality of cities and their surroundings and may also have broader impacts on health, the environment, and potentially contribute to global climate change. Using remotely sensed Landsat imagery, this study identifies brickfield locations and areal expansion between 1990 and 2015 …

The Relationship Between Forest Management And Stream Discharge In Mazumbai And Baga Ii Forest Reserves, Tanga Region, Tanzania, Shannon Duffy

Independent Study Project (ISP) Collection

Deforestation is known to alter hydrology by reducing interception, transpiration and infiltration capacity, and increasing runoff which all leads to higher stream discharge. For rural Tanzanian communities, surface water resources are crucial for meeting basic needs, so the integrity of headwater catchments need to be maintained to ensure their reliability. The objectives of this study were to a) map the streams in the two forests because none currently exist and b) determine the effect of deforestation on discharge variability. Over fifteen days of data collection, this study analyzed variability of discharge and the degree of correlation between discharge and rainfall …

The Importance Of Spatial Data To Open - Access National Archaeological Databases And The Development Of Paleodemography Research, Erick Robinson, Christopher Nicholson, Robert L. Kelly

Sociology, Social Work and Anthropology Faculty Publications

With generous support from the National Science Foundation, we have spent the past four years developing an archaeological radiocarbon database for the United States. Here, we highlight the importance of spatial data for open-access, national-scale archaeological databases and the development of paleodemography research. We propose a new method for analyzing radiocarbon time series in the context of paleoclimate models. This method forces us to confront one of the central challenges to realizing the full potential of national-scale databases: the quality of the spatial data accompanying radiocarbon dates. We seek to open a national discussion on the use of spatial data …

A Least Cost Analysis: Correlative Modeling Of The Chaco Regional Road System, Sean Field, Carrie Heitman, Heather Richards-Rissetto

Department of Anthropology: Faculty Publications

During the ninth through twelfth centuries A.D., Ancestral Pueblo people constructed long, straight roads that interconnected the Chaco regional system across the San Juan Basin of northwestern New Mexico. The intent and use of these features has eluded archaeological consensus, although recent research has reiterated the occurrence of long distance timber importation to Chaco Canyon. To enhance our interpretation of these features we offer a large-scale least cost analysis wherein optimal pathways that are modeled to simulate timber importation are compared to the actual road locations. A series of least cost paths were produced through different energy allocation algorithms, at …

The Law Of Crime Concentration In Midsized Cities: A Spatial Analysis, Hannah Ridner

Masters Theses & Specialist Projects

The geographic concentration of crime led to the proposal of the law of crime concentration in 2015 by David Weisburd. This contribution to crime and place literature needs further research to properly define, measure, and confirm this law. This study builds upon measurement techniques used in previous studies to measure crime concentration across a random sample of mid-sized cities, estimate the expected Gini coefficient in mid-sized cities, and analyze the variation in crime concentration across mid-sized cities. Determining the expected level of crime concentration and whether it varies across cities will advance the literature by providing both a benchmark for …

Measuring And Understanding Food Accessibility In The Tampa Bay Area, Bailey I. Glover

USF Tampa Graduate Theses and Dissertations

In the Tampa Bay region, increasing population and changing demographics have begun to alter the characteristics of established neighborhoods. An increase in suburban growth has triggered a shift in the location and profitability of food establishments in socially disadvantaged neighborhoods. Supermarket closures have garnered attention from public health officials who are concerned with the overall availability of fresh food throughout Hillsborough and Pinellas Counties. Unfortunately, there has been little research surrounding the quality of food sold at establishments in both the Tampa Bay region and abroad. Instead, many geographic studies have chosen to group both fresh and prepared food establishments …

Habitat Suitability Index Model Of The Florida Sandhill Crane (Grus Canadensis Pratensis) In West-Central Florida, Courtney E. Buck

USF Tampa Graduate Theses and Dissertations

The Florida Sandhill Crane (Grus canadensis pratensis) is a state threatened endemic subspecies of the Sandhill Crane (Nesbitt & Tacha, 1997). With a population that was estimated at a maximum of 5,000 individuals in 2003 (Nesbitt & Hatchitt, 2008), it is imperative to identify potentially viable habitats, as Florida is rapidly developing. This research develops a Habitat Suitability Index model to determine unsuitable to optimally suitable habitat locations throughout west-central Florida. To do so, six suitability variables based on the crane’s life history were evaluated: Potential nesting area, immediate nesting area, wetland coverage, foraging area, brooding area, and road proximity. …

Utilizing geographic information systems and remote sensing techniques, this study compares the viewshed characteristics of two proposed routes to connect an existent greenway trail system to Wilson’s Creek National Battlefield in Greene County, MO. Light Detection and Ranging data is then used to map the viewshed of each route and calculate the openness and interconnectedness of each viewshed. High-resolution multispectral imagery is then used to calculate the Normalized Difference Vegetation Index measuring the “greenness” within each viewshed. Finally, parcel-level land use data is used to …

Dependence Of Hydrological Modeling On Spatial Resolution In Lake Whatcom Watershed, Emily Mcginty

Scholars Week

Remotely sensed digital elevation data can be utilized through geographic information science (GIS) techniques to model watershed and stream delineations. These techniques allow analysts to easily produce results that would otherwise require hours of intense field work, if possible at all. The accuracy of these watershed and stream models can be dependent on the resolution of the elevation data, and choosing an inappropriate resolution can result in further analyses producing inaccurate and/or misleading results. The purpose of my research is to quantify the differences between hydrological models developed from elevation data at varying resolutions. I chose the Lake Whatcom watershed …

The Applications Of Gis On Lithic Raw Material Source Analysis, Sydney James, Carolyn Dillian

Honors Theses

Raw material sourcing has long been used to identify patterns of trade and exchange in archaeological research. More recently, geographic information systems (GIS) have provided other ways for archaeologists to identify these patterns through data visualization and various spatial statistical analyses. While these methods are frequently used individually, the combined use of these methods has potential to more closely examine the relationships between raw material sources and archaeological sites; this should be considered a necessary measure for methods of spatial analysis. This research applies existing raw material source data to quantitative GIS analysis as a way to demonstrate this claim.

Mapping Wilderness Character In Adams County, Pennsylvania, Alyssa J. Kaewwilai

Gettysburg Social Sciences Review

The spatial trends in wilderness character in Adams County, Pennsylvania were examined to evaluate how influenced specific areas are impacted by human activity and development. Indicators of wilderness character were selected as natural, untrammelled, undeveloped, along with solitude and unconfined recreation by the Death Valley National Park staff in which a 0-4 ranking system was based upon to portray a range of most degraded to optimal land. This was executed through examination of factors such as abundance of biodiversity and human development within the given area before a Monte Carlo simulation was run to show sensitivity of change. It was …

The database is designed to represent surficial geologic deposits contained in a polygon shapefile. Throughout the State of Nevada each polygon represents a mapped geologic unit at a scale of at least 1:250 k. Each mapped geologic unit is then assigned a “potential fossil yield classification”, a numerical ranking value of 1-5 based …

Analyzing Trends And Patterns In Adverse Birth Outcomes In Massachusetts From 2000-2014, Madeleine Haynes

International Development, Community and Environment (IDCE)

This study explores spatio-temporal trends and patterns in adverse birth outcomes (ABO) in the state of Massachusetts from 2000-2014. ABO include low birth weight (< 2500 g) and preterm deliveries (gestational age < 37 weeks). This research evaluates if there are areas in Massachusetts that have experienced statistically significant increases or decreases in ABO throughout the study period. Birth data was obtained from the Massachusetts Department of Public Health and only singleton, live births were included for the analysis. The data were aggregated to census tracts, and the total number of births and the number of ABOs were calculated for each census tract for each year. In total, 1478 census tracts were included in this analysis. Births to non-Hispanic black mothers and births to non-Hispanic white mothers were separated to evaluate if trends in ABO are similar regardless of race as previous literature has identified a much higher rate of ABO in births to non-Hispanic black women. Trends and patterns of ABO were evaluated using the Space Time Cube and the Mann-Kendall statistic and a multivariate regression was conducted to identify potential correlations between socioeconomic factors and prevalence of ABO. Results of this study can be used to identify areas that are experiencing an increase in ABO to potentially allow for more effective, targeted intervention methods.

Using Historic Glo Data And Gis To Assess The Potential For Local Bison Bison Near Two Wisconsin Late Prehistoric Oneota Localities, Andrew Michael Saleh

Theses and Dissertations

Bison (Bison bison) remains are rare in the archaeological record of Wisconsin. This thesis uses a Geographic Information System (GIS) to better understand native vegetation near sites with reported bison bone to assess their ecological viability to support local bison herds. The distribution of bison bone recovered in archaeological contexts in Wisconsin can be summarized as follows: few sites report bison remains, the archaeological contexts that do report bison are clustered in a few Late Prehistoric period locations (approximately A.D. 1300-1650), and bison remains are rare in comparison to other fauna at those sites (Arzigian et al. 1989; Boszhardt 1989, …

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 …

The Value Of Farmland: Mapping Assessor Data To Understand Land Use Change, Lyndi Perry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ideas developed by regional economists have potential applications within the urban planning field. One potential application is toward conserving farmland, and within this thesis this topic is examined for the study area of Utah County, Utah. Using assessor data, a land value map is created and further used to develop a regional economic model and spatial models that were analyzed for patterns of land use change.

Findings show that representing land value as continuous surface maps is a useful approach. The maps reveal that Utah County has densified as its population increased while farmland loss still occurred in agriculturally-important areas. …

Geographical Analysis Of Offender Vulnerability: Modeling Coastal Hazards And Social Disorganization In Southern Mississippi, Ashleigh Nicole Price

Master's Theses

Hazards research continually examines how specific groups are affected by damaging events and how their unique sociodemographic characteristics contribute to variations in resilience and recovery. Studies have shown that underprivileged communities suffer more adversely and take longer to recover from hazard events. Probationers and parolees are uniquely disadvantaged regarding demographics and economic opportunity, both of which contribute to increased vulnerability and reduced resilience. Numerous legal restrictions and widespread discrimination towards former criminals means offenders are often relegated to underserved, criminogenic neighborhoods. Given such severe social and financial limitations, offenders have little capacity to prepare for or recover from disasters.

The …
