Disruption To Ems Service During Flood Scenarios In Western North Carolina, Julia Cardwell

Journal of Rural Social Sciences

Given that the intensity and frequency of flood events will increase under climate change scenarios, the ability to model potential impacts, such as those to healthcare access, will become increasingly important. This study analyzes EMS response time under both a historical (Tropical Storm Fred in August 2021) and a modeled flood event (FEMA’s 100-yr floodplain) in western North Carolina, a predominantly rural area. The results indicate that network disruption during flood events is a concern in the study area, and while the historical event produced moderate disruption, the 100-yr event produced major disruptions throughout the study area. This research emphasizes …

Estimation Of Economic Risk From Coastal Natural Hazards In Louisiana, Rubayet Bin Mostafiz

LSU Doctoral Dissertations

Louisiana, U.S.A., is among the most vulnerable areas globally to coastal natural hazards, with risk vulnerability likely increasing. The risks associated with non-tropical-cyclone hazards in Louisiana’s coastal zone have been understudied. This research enhances present and future (i.e., 2050) Louisiana risk assessment using locally-weighted, model-based hazard frequency/intensity and population projections.

Results suggest that property risks associated with extreme cold temperature and tornado are and will remain costlier than those for hail and lightning. Property risks of extreme cold temperature and hail are projected to decrease with the expected warming temperatures, with those of all four of these hazards peaking in …

A Gis Analysis To Identify Historical, Contemporary, And Spatial Housing Discrimination In Denver, Colorado, Ian Sharkey

Geography and the Environment: Graduate Student Capstones

This study analyzes the relationship between housing discrimination and equity within the City of Denver. This study creates a discrimination index by combining (1) historical Discrimination, (2) contemporary segregation, and (3) housing inequity data into an index to compare the Denver Department of Health and the Environment (DDPHE) 2020 equity index using a local bivariate analysis. This study found a negative linear relationship between the created and Denver equity indexes. The variables used for the discrimination index can explain some of the relationships, but future studies should use more variables for a discrimination index.

Using Gis To Identify Barriers To Access On The Rtd W Line In Denver, Colorado, Tristan Johnson

Geography and the Environment: Graduate Student Capstones

Denver, Colorado has a long history of public transportation usage beginning with horse-drawn streetcars in 1871. As the automobile began to flourish however, the use of public transportation has languished. In 2013, the W light rail line opened serving the West Denver area. As Denver has moved toward a more transit-oriented growth model, this rail line can create a more vibrant future. Using GIS, a better understanding of the barriers to access for light rail travel is obtained and considering key variables outputs are created to assist policy makers in utilizing the W line. By using GIS to address population …

Many humans live in large, complex political centers, composed of multi-scalar communities including neighborhoods and districts. Both today and in the past, neighborhoods form a fundamental part of cities and are defined by their spatial, architectural, and material elements. Neighborhoods existed in ancient centers of various scales, and multiple methods have been employed to identify ancient neighborhoods in archaeological contexts. However, the use of different methods for neighborhood identification within the same spatiotemporal setting results in challenges for comparisons within and between ancient societies. Here, we focus on using a single method—combining Average Nearest Neighbor (ANN) and Kernel Density (KD) …

Background: Food is not equitably available. Deficiencies and generalizations limit national datasets, food security assessments, and interventions. Additional neighborhood level studies are needed to develop a scalable and transferable process to complement national and internationally comparative data sets with timely, granular, nuanced data. Participatory geographic information systems (PGIS) offer a means to address these issues by digitizing local knowledge.

Methods: The objectives of this study were two-fold: (i) identify granular locations missing from food source and risk datasets and (ii) examine the relation between the spatial, socio-economic, and agency contributors to food security. Twenty-nine subject matter experts from three cities …

Shifting Geopolitics: Reimagining Globalization And Spatial Representation In The Post Covid-19 Era, Victoria H. Bergström

The Journal of International Relations, Peace Studies, and Development

Abstract: Since the emergence of the COVID-19 pandemic, the utilisation of maps has been at the forefront. Maps have informed policymakers, governments, and citizens of the distribution and spread of the disease. Although these maps have been used for various purposes, from border closures to curfews, there is an inherent danger in this widespread usage. Aside from the intricacy of these spatial representations, these widely distributed representations encourage isolationism and the reconception of borders in an increasingly globalised world. Furthermore, new connectivities through digital means have created a potential solution to international exchanges amidst physical limitations. Nevertheless, elitism prevents the …

Multi-Decadal Analysis Of Remotely Sensed Vegetation Change In Berea College Forest - Seasonality Of Forest Patterns Using Remote Sensing, Jacob Foushee

The Cardinal Edge

Satellite imagery is a practical and valuable tool for monitoring vegetation condition in forests. The longevity of the USGS/NASA Landsat program along with its medium spatial resolution (30m) gives researchers the ability to make informed statements on land cover generally, and specifically on aspects such as forest conditions. The Landsat program’s nearly 50-year archive of imagery show how Earth’s surface has changed through modern development and how these developments have influenced forests. Google Earth Engine (GEE) is a cloud-based repository of satellite imagery dating as far back as the 1970s. This study utilizes Landsat 5-8 imagery from GEE to calculate …

Minimizing Surface Run-Off, Improving Underground Water Recharging, And On-Site Rain Harvesting In The Kathmandu Valley, Ambika P. Adhikari, Keshav Bhattarai

Himalayan Research Papers Archive

Nepal's political institutions and administrative units were thoroughly restructured in 2015 with the promulgation of the new Constitution. Several rural areas were combined to meet the definition of urban threshold criteria to classify rural areas into urban categories. Accordingly, over 3,900 local political and administrative units were amalgamated into 753 units, of which, 293 units are classified as urban. Within these newly defined urban areas, many natural environments have been converted into impervious surfaces such as paved roads, sidewalks, and building roofs. These impervious surfaces have drastically increased the amount of surface run-offs-often termed as "urban floods"--under increasing precipitation caused …

Context For Reproducibility And Replicability In Geospatial Unmanned Aircraft Systems, Cassandra Howe, Jason A. Tullis

Geosciences Faculty Publications and Presentations

Multiple scientific disciplines face a so-called crisis of reproducibility and replicability (R&R) in which the validity of methodologies is questioned due to an inability to confirm experimental results. Trust in information technology (IT)-intensive workflows within geographic information science (GIScience), remote sensing, and photogrammetry depends on solutions to R&R challenges affecting multiple computationally driven disciplines. To date, there have only been very limited efforts to overcome R&R-related issues in remote sensing workflows in general, let alone those tied to unmanned aircraft systems (UAS) as a disruptive technology. This review identifies key barriers to, and suggests best practices for, R&R in geospatial …

Centers Of Community: A Spatial Analysis Of The Mid-19th Century Populaton Residing On Beacon Hill, Boston, Ma, Justin Malcolm

Graduate Masters Theses

The first Black church constructed in Boston, and the oldest extant Black church building in America, the African Meeting House was located on the North Slope of Beacon Hill; the predominant residence of Boston’s Black population during the nineteenth century. The African Meeting House has been the subject of several important archaeological investigations. In 1840, a schism within the African Meeting House congregation resulted in the establishment of the Twelfth Baptist Church. Historical contexts suggest that this neighborhood was highly segregated. A geographic and statistical analysis of the unique 1850 Boston City Census, which was made to yield spatial contexts …
