An Assessment Of Kentucky Birth Records, Focusing On Early-Onset Hypertensive Disorders Of Pregnancy, Environmental Metal Exposures, And Geocoding Precision, 2008-2017, Courtney J. Walker Jan 2021

An Assessment Of Kentucky Birth Records, Focusing On Early-Onset Hypertensive Disorders Of Pregnancy, Environmental Metal Exposures, And Geocoding Precision, 2008-2017, Courtney J. Walker

Theses and Dissertations--Epidemiology and Biostatistics

Using live and stillbirth records from Kentucky (2008-2017), this dissertation assessed the county-level prevalence and geospatial patterns of early-onset hypertensive disorders of pregnancy (eHDP); examined the geocoding precision of addresses recorded on birth records, and evaluated the association between individual risk factors and environmental metal exposures on eHDP prevalence. After adjusting for maternal demographic factors and pre-existing health conditions, we observed that eHDP prevalence was 38% higher (aPR=1.38, 95%CI:1.16, 1.64) in counties with the highest prevalence of married women (> 53.8%) compared to lower prevalence areas (31.6%) had a 20% higher prevalence of eHDP(aPR=1.20, 95%CI:1.00, 1.44) compared to counties with …


Evaluating St. Catherines Island's Shoreline, Vegetation Line, And The Locations Of Loggerhead Sea Turtle Nests, Sydney O. Davis Jan 2021

Evaluating St. Catherines Island's Shoreline, Vegetation Line, And The Locations Of Loggerhead Sea Turtle Nests, Sydney O. Davis

College of Graduate Studies: Theses & Dissertations

St. Catherines Island is a highly dynamic barrier island on the Georgia coast that is also federally listed critical nesting habitat for loggerhead sea turtles. Understanding how St. Catherines’ shoreline and vegetation is changing over time is geographically important as a potential template for other barrier islands. Measuring sea turtle nest locations will provide insight into their natural patterns and how they adjust those locations on a changing barrier island. Analyzing Moving Boundaries Using R (AMBUR) is implemented in this research to assess the movement of the vegetation and shorelines from 2005-2017 using the End Point Rate (EPR) and Linear …


A Hand-Held Structure From Motion Photogrammetric Approach To Riparian And Stream Asseessment And Monitoring, Joseph M. Dehnert, Joseph Dehnert Jan 2021

A Hand-Held Structure From Motion Photogrammetric Approach To Riparian And Stream Asseessment And Monitoring, Joseph M. Dehnert, Joseph Dehnert

Graduate Student Theses, Dissertations, & Professional Papers

Two of the biggest weaknesses in stream restoration and monitoring are: 1) subjective estimation and subsequent comparison of changes in channel form, vegetative cover, and in-stream habitat; and 2) the high costs in terms of financing, human resources, and time necessary to make these estimates. Remote sensing can be used to remedy these weaknesses and save organizations focused on restoration both money and time. However, implementing traditional remote sensing approaches via autonomous aerial systems or light detection and ranging systems is either prohibitively expensive or impossible along small streams with dense vegetation. Hand-held Structure from Motion Multi-view Stereo (SfM-MVS) photogrammetric …


Use And Improvement Of Remote Sensing And Geospatial Technologies In Support Of Crop Area And Yield Estimations In The West African Sahel, Kaboro Samasse Jan 2021

Use And Improvement Of Remote Sensing And Geospatial Technologies In Support Of Crop Area And Yield Estimations In The West African Sahel, Kaboro Samasse

Electronic Theses and Dissertations

In arid and semi-arid West Africa, agricultural production and regional food security depend largely on small-scale subsistence farming and rainfed crops, both of which are vulnerable to climate variability and drought. Efforts made to improve crop monitoring and our ability to estimate crop production (areas planted and yield estimations by crop type) in the major agricultural zones of the region are critical paths for minimizing climate risks and to support food security planning. The main objective of this dissertation research was to contribute to these efforts using remote sensing technologies. In this regard, the first analysis documented the low reliability …


Exploring Spatial Patterns Of Virginia Tornadoes Using Kernel Density And Space-Time Cube Analysis (1960-2019), Michael J. Allen, Thomas R. Allen, Christopher Davis, George Mcleod, Wolfgang Kainz (Ed.), Dean Kyne (Ed.) Jan 2021

Exploring Spatial Patterns Of Virginia Tornadoes Using Kernel Density And Space-Time Cube Analysis (1960-2019), Michael J. Allen, Thomas R. Allen, Christopher Davis, George Mcleod, Wolfgang Kainz (Ed.), Dean Kyne (Ed.)

Political Science & Geography Faculty Publications

This study evaluates the spatial-temporal patterns in Virginia tornadoes using the National Weather Service Storm Prediction Center’s Severe Weather GIS (SVRGIS) database. In addition to descriptive statistics, the analysis employs Kernel Density Estimation for spatial pattern analysis and space-time cubes to visualize the spatiotemporal frequency of tornadoes and potential trends. Most of the 726 tornadoes between 1960–2019 occurred in Eastern Virginia, along the Piedmont and Coastal Plain. Consistent with other literature, both the number of tornadoes and the tornado days have increased in Virginia. While 80% of the tornadoes occurred during the warm season, tornadoes did occur during each month …


Spatial Patterns Of Crime In District 05, Quito-Ecuador, 2016-2020, Pablo Esteban Ochoa Veloz Jan 2021

Spatial Patterns Of Crime In District 05, Quito-Ecuador, 2016-2020, Pablo Esteban Ochoa Veloz

All Graduate Theses, Dissertations, and Other Capstone Projects

The geography of crime in Ecuador has not been geographically studied. In Quito, few criminal studies have been developed from a geographic approach. This research focuses on studying trends and patterns of crime in Quito`s District 05 by employing spatial analytical tools using GIS (Geographic Information System), statistics and cartographic techniques. This study aims to contribute to the literacy in crime-related topic in the country. Quito´s District 05 houses a representative percentage of the city´s financial services, retail activities, and other tertiary services. This district is among the most important economic business district in the city which attract many people …
