Equity In Microscale Urban Design And Walkability: A Photographic Survey Of Six Pittsburgh Streetscapes, Bradley Bereitschaft

Geography and Geology Faculty Publications

This paper explores inequity in neighborhood walkability at the micro-scale level by qualitatively examining six streetscapes in Pittsburgh, Pennsylvania. A photographic survey is used to highlight differences in the quality and design of the built environment among pairs of streetscapes with high or low social vulnerability but approximately equal quantitative Walk Scores®. The survey revealed discernible differences in the quality and maintenance of the built environment among those in more and less disadvantaged neighborhoods. This was true of several characteristics expected to affect walkability, including enclosure, transparency, complexity, and tidiness. Streetscapes in neighborhoods with high social vulnerability exhibited less contiguous …

Mapping Typical Urban Lulc From Landsat Imagery Without Training Samples Or Self-Defined Parameters, Hui Li, Cuizhen Wang, Cheng Zhong, Zhi Zhang, Qingbin Liu

Faculty Publications

Land use/land cover (LULC) change is one of the most important indicators in understanding the interactions between humans and the environment. Traditionally, when LULC maps are produced yearly, most existing remote-sensing methods have to collect ground reference data annually, as the classifiers have to be trained individually in each corresponding year. This study presented a novel strategy to map LULC classes without training samples or assigning parameters. First of all, several novel indices were carefully selected from the index pool, which were able to highlight certain LULC very well. Following this, a common unsupervised classifier was employed to extract the …

Écrire Et Lire Le Caribou Au Lieu De L’Achever, Jonathan Hope

The Goose

Dans un acte sans précédent de gestion de la faune, le gouvernement libéral du Québec a décidé de capturer les derniers membres d’une harde de caribous des bois en Abitibi et de les enfermer dans un zoo. Biologistes et écologistes ont exprimé, avec raison, leur inquiétude et leur colère; cette situation est aussi consternante d'une perspective littéraire.

A Landscape Of Thermal Inequity: Social Vulnerability To Urban Heat In U.S. Cities, Bruce Coffyn Mitchell

USF Tampa Graduate Theses and Dissertations

A combination of the urban heat island effect and a rising temperature baseline resulting from global climate change inequitably impacts socially vulnerable populations residing in urban areas. This dissertation examines distributional inequity of exposure to urban heat by socially disadvantaged groups and minorities in the context of climate justice. Using Cutter’s hazards-of-place model, variables indicative of social vulnerability and biophysical vulnerability are statistically tested for their associations. Biophysical vulnerability is conceptualized utilizing a urban heat risk index calculated from summer 2010 LANDSAT imagery to measure land surface temperature , structural density through the normalized difference built-up index, and vegetation abundance …

The Mobile Monitoring Of Particulate Matter Through Wearable Sensors And Their Influence On Students' Environmental Attitudes, Joseph M. Abbate

DePaul Discoveries

While we have a comprehensive understanding of air pollutants, and their spatiotemporal characteristics across global, and even regional, scales, we are quite limited in our capacity to monitor neighborhood-scale emissions. The mobile monitoring of air pollution is a growing field, prospectively filling in these gaps while personalizing air quality-based tools and risk assessment. In the present study, we developed wearable sensors for particulate matter (PM); and through a citizen science approach, students of partnering Chicago schools monitored PM concentrations throughout their commutes over a five-day period. While their recorded findings would be used to explore the relationship between PM concentrations …

Reappropriating Public Space In Nanchang, China: A Study Of Informal Street Vendors, Bryan C. Winter

USF Tampa Graduate Theses and Dissertations

Since China's shift to market socialism, many marginalized by this process work as informal street vendors where they reappropriate public space in order to survive―a practice at odds with urban authorities' modernizing agenda. In relation to these competing logics concerning public space's use value versus its exchange value, this dissertation examines the practices, experiences, and agency of informal street vendors working in Sanjingwuwei, an ordinary, yet rapidly gentrifying, neighborhood of Nanchang, capital and largest city of southeastern China's Jiangxi Province. After describing the growth of an informal economy in modern China and providing a history of street vending, I describe …

Identifying Nodes Of Transmission In Disease Diffusion Through Social Media, David Sebastian Lamb

USF Tampa Graduate Theses and Dissertations

The spread of infectious diseases can be described in terms of three interrelated components: interaction, movement, and scale. Transmission between individuals requires some form of interaction, which is dependent on the pathogen, to occur. Diseases spread through the movement of their hosts; they spread across many spatial scales from local neighborhoods to countries, or temporal scales from days to years, or periodic intervals. Prior research into the spread of disease have examined diffusion processes retrospectively at regional or country levels, or developed differential equation or simulation models of the dynamics of disease transmission. While some of the more recent models …

Landsat 15-M Panchromatic-Assisted Downscaling (Lpad) Of The 30-M Reflective Wavelength Bands To Sentinel-2 20-M Resolution, Zhongbin Li, Hankui K. Zhang, David P. Roy, Lin Yan, Haiyan Huang, Jian Li

GSCE Faculty Publications

The Landsat 15-m Panchromatic-Assisted Downscaling (LPAD) method to downscale Landsat-8 Operational Land Imager (OLI) 30-m data to Sentinel-2 multi-spectral instrument (MSI) 20-m resolution is presented. The method first downscales the Landsat-8 30-m OLI bands to 15-m using the spatial detail provided by the Landsat-8 15-m panchromatic band and then reprojects and resamples the downscaled 15-m data into registration with Sentinel-2A 20-m data. The LPAD method is demonstrated using pairs of contemporaneous Landsat-8 OLI and Sentinel-2A MSI images sensed less than 19 min apart over diverse geographic environments. The LPAD method is shown to introduce less spectral and spatial distortion and …

Festival Heterotopias: Spatial And Temporal Transformations In Two Small-Scale Settlements, Bernadette Quinn, Linda Wilks

Articles

This paper reports the findings of research undertaken at two festivals which take place in small-scale settlements: one in a village set in rural western Ireland, the other in a small coastal town set within a largely rural Area of Outstanding Natural Beauty in southern England. It uses Foucault’s concept of heterotopia as an analytical tool to further understandings of how the spatial and temporal interruptions caused by festivals temporarily transform the prevailing social order. The findings attest to the manner in which festivals juxtapose several incompatible spaces, creating a diverse array of social alterations in consequence, and highlight the …

A Historical Geography Of Six And Eight-Man Football In Nebraska, Andrew Husa

Department of Geography: Dissertations, Theses, and Student Research

This thesis serves as both a historical geography of six and eight-man football in Nebraska and a discussion of their relationship to rural depopulation. After beginning with an introduction to six and eight-man football, I present an overview of the entire state, including the historical geography of six and eight-man football teams, backgrounds of schools closing and consolidating, and the new trend of cooperative sports teams. This overview is accompanied by maps at five-year intervals depicting the high schools playing six and eight-man football. Rural depopulation, which has plagued the state since the Great Depression, can be seen expressed in …

Nonmeteorological Influences On Severe Thunderstorm Warning Issuance: A Geographically Weighted Regression-Based Analysis Of County Warning Area Boundaries, Land Cover, And Demographic Variables, Megan L. White, J. Anthony Stallins

Geography Faculty Publications

Studies have shown that the spatial distribution of severe thunderstorm warnings demonstrates variation beyond what can be attributed to weather and climate alone. Investigating spatial patterns of these variations can provide insight into nonmeteorological factors that might lead forecasters to issue warnings. Geographically weighted regression was performed on a set of demographic and land cover descriptors to ascertain their relationships with National Weather Service (NWS) severe thunderstorm warning polygons issued by 36 NWS forecast offices in the central and southeastern United States from 2008 to 2015. County warning area (CWA) boundaries and cities were predominant sources of variability in warning …

Bat Community Composition And Monitoring For White-Nose Syndrome At First State National Historical Park, Delaware And Pennsylvania, Juliet Nagel, J. Edward Gates

United States National Park Service: Publications

Abstract

In recent years, bats have faced increasingly deadly threats on multiple fronts. Cave-dwelling bats have been decimated by the emergence of a disease, white-nose syndrome (WNS), caused by a fungal pathogen, Pseudogymnoascus destructans; and tree bats are dying in large numbers at wind power facilities. First State National Historical Park (FRST) is a new national park unit located in northern Delaware and Pennsylvania. Prior to this study, little information was available on bat species and their activity and distribution within FRST. To fill this knowledge gap, we conducted an inventory of bat species present at FRST. We used …

Examining The Use Of Amazon's Mechanical Turk For Edge Extraction Of The Occlusal Surface Of Fossilized Bovid Teeth, Gregory J. Matthews, George K. Thiruvathukal, Maxwell P. Luetkemeier, Juliet K. Brophy

Faculty Publications

In order to reconstruct environments associated with Plio-Pleistocene hominins in southern Africa, researchers frequently rely upon the animals associated with the hominins, in particular, animals in the Family Bovidae. Bovids in southern Africa are typically identified by their teeth. However, identifying the taxon of a bovid tooth is challenging due to various biasing factors. Furthermore, inaccurate identification of fossil bovids can have significant consequences on the reconstructed paleoenvironment. Recent research on the classification of bovid fossil teeth has relied on using elliptical Fourier analysis to summarize the shape of the outline of the occlusal surface of the tooth and the …

Sustainable Recommendation Domains For Scaling Agricultural Technologies In Tanzania, Francis K. Muthoni, Zhe Guo, Mateete Bekunda, Haroon Sseguya, Fred Kizito, Frederick Baijukya, Irmgard Hoeschle-Zeledon

All Peer-Reviewed Publications

Low adoption of sustainable intensification technologies hinders achievement of their potential impacts on increasing agricultural productivity. Proper targeting of locations to scale-out particular technologies is a key determinant of the rate of adoption. Targeting locations with similar biophysical and socio-economic characteristics significantly increases the probability of adoption. Areas with similar biophysical and socio-economic characteristics are referred to as recommendation domains (RDs). This study used geospatial analysis to delineate sustainable recommendation domains (SRDs) for scaling improved crop varieties and good agronomic practices in Tanzania. The study uses K-means clustering to identify relatively similar clusters from grid raster's representing biophysical and socio-economic …

High Resolution Spectra Of Carbon Monoxide, Propane And Ammonia For Atmospheric Remote Sensing, Christopher Andrew Beale

OES Theses and Dissertations

Spectroscopy is a critical tool for analyzing atmospheric data. Identification of atmospheric parameters such as temperature, pressure and the existence and concentrations of constituent gases via remote sensing techniques are only possible with spectroscopic data. These form the basis of model atmospheres which may be compared to observations to determine such parameters. To this end, this dissertation explores the spectroscopy of three molecules: ammonia, propane and carbon monoxide.

Infrared spectra have been recorded for ammonia in the region 2400-9000 cm^-1. These spectra were recorded at elevated temperatures (from 293-973 K) using a Fourier Transform Spectrometer (FTS). Comparison between …

Potential Impacts Of Accelerated Sea-Level Rise And Hurricane-Induced Storm Surge In Western Pasco County, Florida, Kittiya Harris

USF Tampa Graduate Theses and Dissertations

Sea levels have risen approximately 20 cm since the beginning of the 20th century and more than 3 cm in the past 20 years, suggesting that global sea level rise is accelerating. As sea levels continue to rise and storms become more intense, coastal property and populations become more susceptible to damage. Florida is especially vulnerable to hurricane-induced storm surge (HSS) and the onset of accelerated sea-level rise (ASLR) due to its extensive coastline and high population density along the coast. The main purpose of this research is to assess the potential economic impacts of ASLR and HSS for two …

Spatial Analysis Of Tornado Warning System Understanding And Relationship With Tornado Occurrence, Chesnea A. Skeen

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

Tornadoes present a significant threat to life and property. The National Weather Service watch and warning system warns the public of tornadoes. If these warnings are not heeded by the public, the potential fatalities and destruction of property cannot be minimized. Thus, to prevent further loss of life and property, it is necessary to understand how the public understands the watch and warning system, as well as how they react. This paper aims to understand the correlation between understanding of watches and warnings and the occurrence of tornadoes, as well as how understanding varies spatially. Survey data were collected from …

The Political Man As A Sick Animal: On The “Ideology Of Kisêdjê Political Leadership”, André Drago

Tipití: Journal of the Society for the Anthropology of Lowland South America

Eloquent, wise, generous; in short, “exemplary,” Kisêdjê political leaders are also said to be “animal-like” dangerous beings. For Anthony Seeger, this “ideological ambivalence” expresses the contradiction which constitutes the leader’s position-function, whose “political power” working at the center of the village derives from peripheral kinship affiliations. Moreover, supposed to withhold the group’s “norms”, he is surprisingly entitled to violate them–primarily, he is exempted from uxorilocality. I try to demonstrate that the inflections the leader subjects patterns of kinship-making process alter his body and agency, rendering him more or less human and, therefore, capable of mediating between the Kisêdjê and their …
