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 2016 The University of Southern Mississippi

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.

The exhibit – and the map in particular – provides a new layer of access to our digitized collections. The map uses advanced searching to display images from CONTENTdm within the map and allows users to search across our collections in two clicks. This presentation will discuss technical issues related to ...


Exploring The Human Body Space: A Geographical Information System Based Anatomical Atlas, Antonio Barbeito, Marco Painho, Pedro Cabral, João Goyri O'Neill 2016 The University of Maine

Exploring The Human Body Space: A Geographical Information System Based Anatomical Atlas, Antonio Barbeito, Marco Painho, Pedro Cabral, João Goyri O'Neill

Journal of Spatial Information Science

Anatomical atlases allow mapping the anatomical structures of the human body. Early versions of these systems consisted of analogical representations with informative text and labeled images of the human body. With computer systems, digital versions emerged and the third and fourth dimensions were introduced. Consequently, these systems increased their efficiency, allowing more realistic visualizations with improved interactivity and functionality. The 4D atlases allow modeling changes over time on the structures represented. The anatomical atlases based on geographic information system (GIS) environments allow the creation of platforms with a high degree of interactivity and new tools to explore and analyze the ...


A Context-Sensitive Conceptual Framework For Activity Modeling, Rahul Deb Das, Stephan Winter 2016 The University of Maine

A Context-Sensitive Conceptual Framework For Activity Modeling, Rahul Deb Das, Stephan Winter

Journal of Spatial Information Science

Human motion trajectories, however captured, provide a rich spatiotemporal data source for human activity recognition, and the rich literature in motion trajectory analysis provides the tools to bridge the gap between this data and its semantic interpretation. But activity is an ambiguous term across research communities. For example, in urban transport research activities are generally characterized around certain locations assuming the opportunities and resources are present in that location, and traveling happens between these locations for activity participation, i.e., travel is not an activity, rather a mean to overcome spatial constraints. In contrast, in human-computer interaction (HCI) research and ...


Μ-Shapes: Delineating Urban Neighborhoods Using Volunteered Geographic Information, Matt Aadland, Christopher Farah, Kevin Magee 2016 The University of Maine

Μ-Shapes: Delineating Urban Neighborhoods Using Volunteered Geographic Information, Matt Aadland, Christopher Farah, Kevin Magee

Journal of Spatial Information Science

Urban neighborhoods are a unique form of geography in that their boundaries rely on a social definition rather than a well-defined physical or administrative boundary. Currently, geographic gazetteers capture little more than then the centroid of a neighborhood, limiting potential applications of the data. In this paper, we present µ-shapes, an algorithm that employs fuzzy-set theory to model neighborhood boundaries suitable for populating gazetteers using volunteered geographic information (VGI). The algorithm is evaluated using a reference dataset and VGI from the Map Kibera Project. A confusion matrix comparison between the reference dataset and µ-shape's output demonstrated high sensitivity and ...

Les Rues Des Tableaux: The Geography Of The Parisian Art Market 1815-1955, Léa Saint-Raymond, Félicie De Maupeou, Julien Cavero

Artl@s Bulletin

Building upon a preliminary socioeconomic analysis of the art dealers in Paris between 1815 and 1955 (ARTL@S Bulletin 2, n°2), this paper presents the findings of a spatial study of the Parisian art market in this period. Using serial geographical data drawn from a single, consistent source – the Bottin du commerce – we mapped the spatial evolution of art dealers over 140 years, using a geocoding system with composite locators. The article explores the different spatial dynamics of this market, and seeks to shed light on the links between the evolution of the Parisian economy as a whole and ...


Increasing Accessibility For Map Readers With Acquired And Inherited Color Vision Deficiencies: A Re-Coloring Algorithm For Maps, Gretchen M. Culp 2016 Graduate Center, City University of New York

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

All Graduate Works by Year: 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 ...


Planning For Bike Share Connectivity To Rail Transit, Greg P. Griffin, Ipek N. Sener 2016 Texas A&M Transportation Institute

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 ...


The "Adam Cube" : Categorizing Portland, Oregon's Urbanization Using Gis And Spatial Statistics, Jeremy Grotbo 2016 Portland State University

The "Adam Cube" : Categorizing Portland, Oregon's Urbanization Using Gis And Spatial Statistics, Jeremy Grotbo

Dissertations and Theses

Transportation availability and land use intensity demonstrate a strong relationship, with intense development concentrated near significant transportation investment. Transportation networks evolved in response to emergent transportation technologies and changing urban land uses. The irregular distribution of transportation systems reinforced patterns of land use development, shaping urban form. Understanding the relationships between transportation and the intensity of land uses allows urban geographers and city planners to explain the urbanization processes, as well as to identify areas historically susceptible to future development. The goal of this research is to develop a quantitative framework for the analysis of the development of urban form ...

Global Population Distributions And The Environment : Discerning Observed Global And Regional Patterns., Jeremiah J. Nieves 2016 University of Louisville

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 ...

Geography Of Health Care Access: Measurement, Analyses And Integration, Huairen Ye 2016 University of Tennessee - Knoxville

Geography Of Health Care Access: Measurement, Analyses And Integration, Huairen Ye

Doctoral Dissertations

This dissertation addresses the geography of healthcare access and disparity issues in the United States using geospatial methods. Disparities in access to quality healthcare services are of great concern in the field of both public health and geography. Access is a key element within the healthcare delivery system, influenced by both spatial factors and non-spatial factors. Focusing on the spatial dimensions of access, an innovative contribution of this dissertation is the integration of spatial modeling, geo-statistics and location problems in a Geographic Information System (GIS) environment to investigate healthcare access.

Improving health access begins with developing reliable methods to measure ...
