Potential Of Spatial Analysis Of Housing Submarkets In Understanding Residential Segregation, Sungsoon Hwang Nov 2012

Potential Of Spatial Analysis Of Housing Submarkets In Understanding Residential Segregation, Sungsoon Hwang

Sungsoon Hwang

Residential segregation has important implications for social mobility, namely through achievement gap by neighborhoods. The endeavor to unravel processes leading to residential segregation can benefit from empirical analysis of housing submarkets. This paper discusses how spatial analysis of housing submarkets might be useful in exploring patterns and processes of residential segregation. As a case study, housing submarkets in St. Louis and Cincinnati are empirically delineated using fuzzy clustering, and differences in spatial pattern of residential segregation in these two metropoiltan areas are discussed.

Spatial Discrepancies Between Nhdplus And Lidar-Derived Stream Networks, Nicole Marie Samu May 2012

Spatial Discrepancies Between Nhdplus And Lidar-Derived Stream Networks, Nicole Marie Samu

Masters Theses

Many organizations demand that current water resource issues necessitate improved stream network mapping for more accurate and reliable watershed analysis and modeling results, which can ultimately enable better management and policy decisions. Stream network data from the National Hydrography Dataset Plus (NHDPlus) and derived from Light Detection and Ranging (LIDAR) are each widely accepted to be of superior quality compared to many other conventional datasets. Each dataset indicates potential to improve a wide range of water resource applications; NHDPlus for its high spatial accuracy and functionality, and LIDAR-derived networks for their high resolutions. NHDPlus is publicly available and widely used; …

Measuring Accessibility To Primary Care Physicians In The Nashville Metropolitan Statistical Area, Sami M. Almudaris Dec 2011

Measuring Accessibility To Primary Care Physicians In The Nashville Metropolitan Statistical Area, Sami M. Almudaris

Masters Theses & Specialist Projects

The growing concern for the shortage of primary care physicians (PCPs) prompted a government legislation to designate areas where shortage in the delivery of primary care services occurs. The implemented systems (e.g., HPSA, MUA, and MUP) analyze utilization of health services within confined administrative units and fail to account for spatial interactions that occur across administrative borders. This research examines the spatial accessibility to PCPs and the underlying demographic and socioeconomic settings. With the Nashville Metropolitan Statistical Area (MSA) as a study area, this study utilized data from the U.S. Census 2000 and 2010, as well as the known locations …

High School Graduation And Dropout Rates In The Pikes Peak Region Of Colorado: A Spatial Analysis Of School Proximity To Military Installations, Rachel Orlicky Jun 2011

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 …

Social Disorganization And Sex Offenders In Minneapolis, Mn: A Socio-Spatial Analysis, Joseph Koncur Jan 2011

Social Disorganization And Sex Offenders In Minneapolis, Mn: A Socio-Spatial Analysis, Joseph Koncur

All Graduate Theses, Dissertations, and Other Capstone Projects

Using a combination of techniques stemming from the spatial analysis approach of Geography, structural-functionalist theory in Sociology, and an ecological perspective of Criminology, this thesis addresses where sex offenders reside and why. Analyses were performed using the twin cities of Minneapolis and St. Paul, Minnesota as a typical urban setting. The study fuses multiple disciplines work on the complex social problem of released risk level III sex offender management in a spatially-conscious, micro-scale analysis attempting to understand the distribution of released offenders and the relevance of social disorganization theory in explaining their distribution. Socio-economic status and family disruption are tested …

The Influence Of Meteorological Parameters On Rainfall And Severe Weather In Pinellas County, Fl, Cristina A. Mazza Jan 2011

The Influence Of Meteorological Parameters On Rainfall And Severe Weather In Pinellas County, Fl, Cristina A. Mazza

USF Tampa Graduate Theses and Dissertations

Pinellas County is located on a peninsula in Florida that experiences daily patterns of sea breeze associated rainfall mainly during the summer months of June through August. Previously, rainfall patterns, amounts and timing and severe weather in Pinellas County have not been examined considering dominant wind flow patterns, sea breeze circulations and other atmospheric variables. To improve forecasting of local mesoscale phenomena, this project examined the rainfall patterns, amounts and timing and severe weather occurrences that occur as a result of sea breezes and associated prevailing wind regimes within Pinellas County for the months of June, July and August for …

Mapping The Mahajanga Basin: Using Gis To Explore Spatial Relationships In Madagascar's Geology And Paleontology, Anne Brown Apr 2010

Mapping The Mahajanga Basin: Using Gis To Explore Spatial Relationships In Madagascar's Geology And Paleontology, Anne Brown

Geography Honors Projects

Tha Mahajanga Basin, located in northwestern Madagascar, is a region of intense geological and paleontological study, but has never before been subject to spatial analysis. Since 1993, expeditions conducted by Stony Brook University, Macalester College, and the University of Antananarivo have uncovered a rich sampling of more than six thousand specimens and observations including fossils of non-avian dinosaurs, crocodiles, and turtles. This paper analyzes the spatial relationships between paired groups within the fossil record as well as wider regional trends to address paleoenvironment. A combination of spatial analysis and statistics are used to determine the patterns existing between fossils or …

Multivariate Visualization And Analysis Of Photomapped Artifact Scatters, Nathan M. Craig, Aldenderfer Mark Jan 2006

Multivariate Visualization And Analysis Of Photomapped Artifact Scatters, Nathan M. Craig, Aldenderfer Mark

Nathan M Craig

Simultaneous analysis of relationships between multiple artifact classes is required for characterization of many types of activity areas. This paper illustrates improved forms of multivariate visualization, spatial analysis and integration of experimental results that are possible with GIS based photomapping. Techniques are demonstrated through analysis of a hearth associated artifact scatter exposed during excavations of a Late Archaic pithouse at Jiskairumoko, Peru. A multivariate density raster is created and additive color visualization is used for simultaneous display of three artifact distributions. Performing unconstrained clustering in a GIS, space is classified by simultaneous relative density relationships between multiple object types.
