High School Graduation And Dropout Rates In The Pikes Peak Region Of Colorado: A Spatial Analysis Of School Proximity To Military Installations, Rachel Orlicky

Geography and the Environment: Graduate Student Capstones

The purpose of this project was to examine graduation and dropout rates for high school students to determine if a correlation could be found with respect to the relative school distance from a military installation in the Pikes Peak region. Spatial analysis and Ordinary Least Squares analysis were used to build a linear regression model to predict student graduation and dropout rates. The results for the total student population for graduation rates and for dropout rates showed no statistically significant correlation with respect to the relative proximity to a military installation. Detailed analysis revealed that several minority and gender subgroups …

Mapping In Philanthropy: Exploring The Use Of Mapping In Foundation Grantmaking, Jim Casey

Geography and the Environment: Graduate Student Capstones

Foundations provide grants to nonprofit organizations in our communities, who then provide services locally. Choosing which nonprofit to fund, and which not to fund is difficult. This study examines current uses and upcoming uses of mapping and Geographic Information Systems (GIS) as part of funding decisions made by foundations. Foundations engaged in strategic funding, especially that which targets specific populations are more likely to use GIS and geospatial analysis in funding decisions. Grantmaking in response to proposals requires less strategic analysis and calls for mapping much less by comparison. As a field, nationally foundations and nonprofits have identified many uses …

Developing Tornado Climatology In The Southern Great Plains Per Phases Of Prominent Oceanic Oscillations, Nicholas M. Fillo

Geography and the Environment: Graduate Student Capstones

Meteorologists are continually working toward a greater understanding of which atmospheric environments are most conducive for tornado development. This Capstone project analyzed tornado occurrences across Texas, Oklahoma, Arkansas and Louisiana during the period 1950 through 2009 to determine if any correlation exists between the location and frequency of tornado activity and the phases of the El Nino-Southern Oscillation, the Atlantic Multidecadal Oscillation and the Pacific Decadal Oscillation. While it was determined that no phase of any of the oscillations studied was significantly more dominant over the other(s) concerning frequency, this project does identify some spatial shifts in tornado activity depending …

Using Geographically Weighted Regression Models To Analyze Crash Harm, Libin Zheng

Civil & Environmental Engineering Theses & Dissertations

Society pays a high cost for collisions in terms of property damage, injuries and loss of life. This paper has two objectives. One is to examine various factors associated with harm caused by highway collisions. Both global OLS and local GWR models are provided to identify specific variables influencing crash harm. Another objective is to demonstrate the use of a Geographically Weighted Regression (GWR) method in this complex safety problem, which can estimate models for each crash location and show spatial variation. The results show that the GWR model is a significant improvement on the OLS model; the test for …

Evaluating The Effectiveness Of Widely Available 3-D Visualization Tools In Support Of Public Participation, Laxmi Ramasubramanian, Jennifer L. Weeks, Tim Case

Publications and Research

There is a persistent need for improved tools and techniques to facilitate public involvement in transportation decision making. Despite continuous improvements in increasing public involvement at all phases of transportation decision making, transportation agencies are still seeking more affordable, accessible, and effective means of communicating with a wide range of stakeholders. The report documents a survey of a wide variety of transportation agencies on their use of interactive 3-D visualization for public involvement using an electronic survey. Supplemental qualitative data was generated through telephone interviews with selected survey participants. It concludes with three case studies illustrating applications of interactive 3-D …

Modeling Geographic Population Dispersion Utilizing Geospatial Information System Environment Agents In An Agent Based Model, Karl D. Liebert

Computational Modeling & Simulation Engineering Theses & Dissertations

New capabilities in agent based model (ABM) environments are opening the door to the creation of ABM that may incorporate high-quality, real world environment data in the form of Geospatial Information System (GIS) files . In the past, GJS environments were only possible through extensive software development efforts focused on specific model applications.

This thesis explores the value and issues of using GIS data to provide an ABM environment. It examines the ability of ABM development environments (DE) to support GIS environment data. The selected ABM DE is then used to model population behavior in an environment defined by authoritative …

People, Pixels, & Weights: Some Novel Applications Of Remote Sensing And Geographically Weighted Regression For Evansville, Indiana, Eric W. Lafary

All-Inclusive List of Electronic Theses and Dissertations

The exploration of urban-environmental changes and how those transformations co-vary with observed socio-economic realities is currently a major research initiative in geography. To that end, this thesis develops an urban-environmental assessment regime that examines how environmental change co-varies with observed socio-economic conditions. Research has demonstrated existing linkages between observed conditions in regard to socio-economic status (SES) and a particular greenness index, as represented by, normal difference vegetation index (NDVI). However, a gap within the literature has been identified concerning the current methodologies that propose to predict SES using remotely sensed data. Therefore, this thesis addresses this gap within the related …
