The Invisible People Of The Invisible Coast: The Resilience Of People Experiencing Homelessness To Disasters On The Alabama, Louisiana, And Mississippi Gulf Coasts, Nicole Elizabeth Callais Aug 2016

The Invisible People Of The Invisible Coast: The Resilience Of People Experiencing Homelessness To Disasters On The Alabama, Louisiana, And Mississippi Gulf Coasts, Nicole Elizabeth Callais

Master's Theses

While extensive research has been conducted on vulnerability and resilience with regard to hazards, very few studies have researched the resilience of homeless populations. The Gulf Coast region is densely populated and susceptible to natural and anthropogenic hazards. Climate change studies indicate that this region will experience an increase in severe and intense tropical cyclones[1], thereby increasing the risk of experiencing adverse impacts from future coastal hazards. While local government agencies in this region have policies in place to protect communities, these policies tend to exclude any action regarding the evacuation and safety of the homeless population.

In this thesis, I created a novel geoscience data visualization framework and applied interface automata theory to geoscience data visualization tasks. The framework can support heterogeneous geoscience data and facilitate data operations. The interface automata …


Tornado Density And Return Periods In The Southeastern United States: Communicating Risk And Vulnerability At The Regional And State Levels, Michelle Bradburn Aug 2016

Tornado Density And Return Periods In The Southeastern United States: Communicating Risk And Vulnerability At The Regional And State Levels, Michelle Bradburn

Electronic Theses and Dissertations

Tornado intensity and impacts vary drastically across space, thus spatial and statistical analyses were used to identify patterns of tornado severity in the Southeastern United States and to assess the vulnerability and estimated recurrence of tornadic activity. Records from the Storm Prediction Center's tornado database (1950-2014) were used to estimate kernel density to identify areas of high and low tornado frequency at both the regional- and state-scales. Return periods (2-year, 5-year, 10-year, 25-year, 50-year, and 100-year) were calculated at both scales as well using a composite score that included EF-scale magnitude, injury counts, and fatality counts. Results showed that the …

Michigan Tech Publications, Part 1

Woodland vernal pools are important, small, cryptic, ephemeral wetland ecosystems that are vulnerable to a changing climate and anthropogenic influences. To conserve woodland vernal pools for the state of Michigan USA, vernal pool detection and mapping methods were sought that would be efficient, cost-effective, repeatable and accurate. Satellite-based L-band radar data from the high (10 m) resolution Japanese ALOS PALSAR sensor were evaluated for suitability in vernal pool detection beneath forest canopies. In a two phase study, potential vernal pool (PVP) detection was first assessed with unsupervised PALSAR (LHH) two season change detection (spring when flooded—summer when dry) and validated …


"Gravity Models" Applied To Projections For New Casinos: Techniques And Results, Will E. Cummings Jun 2016

"Gravity Models" Applied To Projections For New Casinos: Techniques And Results, Will E. Cummings

International Conference on Gambling & Risk Taking

All developers of new casinos prepare, or have prepared for them, projections for the likely gaming-revenue performance of those casinos; in many cases; regulatory authorities in North America also require or commission independent third-party assessments of such performance. These projections are very frequently based on "gravity models," applying techniques pioneered by Reilly and Huff to analyze other retail activities in relation to the geographic distribution of competitors and potential customers. In this paper, I review roughly 80 examples of such applications from recent casino-licensing procedures in the U.S., and compare their results.

Increasing Accessibility For Map Readers With Acquired And Inherited Color Vision Deficiencies: A Re-Coloring Algorithm For Maps, Gretchen M. Culp

Dissertations, Theses, and Capstone Projects

Approximately 8% of the male population suffer from an inherited form of color vision deficiency (CVD). Age, diabetes, macular degeneration, cataracts and glaucoma result in eye defects including an acquired form of CVD. Inherited CVD is marked by a difficulty in discerning red from green, while acquired CVD is marked by a difficulty in discerning blue from green. A recent review of the cartographic literature revealed a deficit in studies on accessible maps for readers with the acquired form of CVD. In addition, research on accessible maps for readers with the inherited form of CVD was restricted to the design …

An approach for automated registration of Landsat-8 OLI L1T and Sentinel-2A MSI L1C data is presented and demonstrated using contemporaneous sensor data. The approach is computationally efficient because it implements feature point detection across four image pyramid levels to identify a sparse …


Planning For Bike Share Connectivity To Rail Transit, Greg P. Griffin, Ipek N. Sener Jun 2016

Planning For Bike Share Connectivity To Rail Transit, Greg P. Griffin, Ipek N. Sener

Journal of Public Transportation

Bike sharing can play a role in providing access to transit stations and then to final destinations, but early implementation of these systems in North America has been opportunistic rather than strategic. This study evaluates local intermodal plan goals using trip data and associated infrastructure such as transit stops and bike share station locations in Austin, Texas, and Chicago, Illinois. Bike sharing use data from both cities suggest a weak relationship with existing rail stations that could be strengthened through collaborative, intermodal planning. The study suggests a planning framework and example language that could be tailored to help address the …


Can Significant Trends Be Detected In Surface Air Temperature And Precipitation Over South America In Recent Decades?, Daniel De Barros Soares, Huikyo Lee, Paul C. Loikith, Armineh Barkhordarian, Carlos R. Mechoso Jun 2016

Can Significant Trends Be Detected In Surface Air Temperature And Precipitation Over South America In Recent Decades?, Daniel De Barros Soares, Huikyo Lee, Paul C. Loikith, Armineh Barkhordarian, Carlos R. Mechoso

Geography Faculty Publications and Presentations

Trends in near-surface air temperature and precipitation over South America are examined for the periods 1975–2004 and 1955–2004, respectively, using multiple observational and climate model data sets. The results for observed near-surface air temperature show an overall warming trend over much of the continent, with the largest magnitudes over central Brazil. These observed trends are found to be statistically significant using pre-industrial control simulations from the fifth phase of the Coupled Model Intercomparison Project (CMIP5) as the baseline to estimate natural climate variability. The observed trends are compared with those obtained in natural-only CMIP5 simulations, in which only natural forcings …


Applications Of Satellite Geodesy In Environmental And Climate Change, Qian Yang May 2016

Applications Of Satellite Geodesy In Environmental And Climate Change, Qian Yang

USF Tampa Graduate Theses and Dissertations

Satellite geodesy plays an important role in earth observation. This dissertation presents three applications of satellite geodesy in environmental and climate change. Three satellite geodesy techniques are used: high-precision Global Positioning System (GPS), the Gravity Recovery and Climate Experiment (GRACE) and Interferometric Synthetic Aperture Radar (InSAR). In the first study, I use coastal uplift observed by GPS to study the annual changes in mass loss of the Greenland ice sheet. The data show both spatial and temporal variations of coastal ice mass loss and suggest that a combination of warm atmospheric and oceanic condition drove these variations. In the second …

The Origin And Expansion Of The Eastern Red Fox, Adrienne Egge Kasprowicz May 2016

The Origin And Expansion Of The Eastern Red Fox, Adrienne Egge Kasprowicz

LSU New Orleans Theses and Dissertations

When new populations are first identified in a region there are multiple potential sources: introduction of a non-native species, extra-range expansion of a nearby population, or demographic growth of a previously unnoticed species. Red foxes were absent or rare in the mid-eastern portion United States until the late 1800s. Their origins potentially include natural population increase/expansion, translocations from Europe, and, eventually, 20th century fur farming. In this study I attempt to identify the relative impact of native expansion versus human mediated introductions of both colonial era European foxes and early 20th century fur-farm foxes on the establishment of red …


Using Residential Location To Assess The Environmental Value-Action Gap Of Students At James Madison University, Emma Rose Martin May 2016

Using Residential Location To Assess The Environmental Value-Action Gap Of Students At James Madison University, Emma Rose Martin

Senior Honors Projects, 2010-2019

This study focuses on the environmental Value-Action Gap of students at James Madison University (JMU) in Harrisonburg, Virginia. This gap occurs when a person has pro-environmental beliefs but does not have congruent actions. Often, there are other factors apart from a person’s values that influence his/her willingness to participate in eco-friendly behavior (Howell 2013). For this study, the factor of influence being addressed is location. When students live on-campus at JMU they are surrounded by ‘green’ initiatives. Understanding the diffusion of environmental behavior from on-campus living to off-campus living is important because the majority of a JMU student’s residency is …
