Race And “Hotspots” Of Preventable Hospitalizations, Caryn N. Bell, Janice V. Bowie, Roland J. Thorpe Jr.

Journal of Health Disparities Research and Practice

Abstract

Preventable hospitalizations (PHs) are those for ambulatory care-sensitive conditions that indicate insufficiencies in local primary healthcare. PH rates tend to be higher among African Americans, in urban centers, rural areas and areas with more African American residents. The objective of this study is to determine geographic clusters of high PH rates (“spatial clusters”) by race. Data from Maryland hospitals were utilized to determine the rates of PHs in zip code tabulation areas (ZCTAs) by race in 2010. Geographic clusters of ZCTAs with higher than expected PH rates were identified using Scan Statistic and Anselin’s Local Moran’s I. 10 PH …

Gis Investigation Of Crime Prediction With An Operationalized Tweet Corpus, Anthony J. Corso, Abdulkareem Alsudais

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Social media as the de facto communication channel is being used to disseminate one’s diurnal self-revelations. This profound discovery often contains double-talk, peculiar insights, or contextual information about real-world events. Natural language processing is regularly used to uncover both obvious and latent knowledge claims within disclosures published amid the complex environment. For example, a perpetrator with first-hand knowledge of their criminal incident uses social media to post critical information about it. A geographic information system (GIS) is capable of large-scale point data analysis and possesses methods that enable dataset processing, evaluation, and automatic spatial visualization. Such an artifact—fused with traditional …

Using Mobile Geographic Information Systems To Improve Operational Efficiency, Data Reliability, And Access In Mine Action, Paul Rittenhouse, Lindsay Aldrich

The Journal of Conventional Weapons Destruction

The inherently complex field of mine action, with its many political, financial, and physical considerations, is also a spatial, data-driven field; and as a result, geographic information systems (GIS) stand to play a major role. Spatial data can help address questions such as: Where are the hazardous areas and what has been cleared or cancelled? Where have teams already surveyed? Where should they go next? How many square meters have been cleared? Due to the complexities surrounding assigning tasks and prioritization, standard operating procedures (SOP), quality assurance/quality control (QA/QC) and database design, GIS often gets limited to high-level planning, database …

Streambank Erosion Mapping On The Nottoway River Using Gps-Based Above-Water Video, Emine Fidan

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

This project concerns the development of streambank erosion maps on military installations utilizing GPS-based above-water video mapping and image georeferencing techniques. The river mapped was the Nottoway River at the Fort Pickett military installation on October 10-11, 2015. Kayak-mounted above-water cameras were utilized to capture georeferenced images of streambank erosion. These GIS-based erosion classifications were utilized to develop erosion maps for determining streambank erosion conditions along the river. Areas of high erosion were identified as about two percent of the river (2167 ft. of streambank length). These maps allow for the opportunity to revisit the sites to determine changes in …

Comparison Of Terrain Indices And Landform Classification Procedures In Low-Relief Agricultural Fields, Derek A. Evans, Karl W. J. Williard, Jon E. Schoonover

Journal of Geospatial Applications in Natural Resources

Landforms control the spatial distribution of numerous factors associated with agronomy and water quality. Although curvature and slope are the fundamental surface derivatives used in landform classification procedures, methodologies for landform classifications have been performed with other terrain indices including the topographic position index (TPI) and the convergence index (CI). The objectives of this study are to compare plan curvature, the convergence index, profile curvature, and the topographic position index at various scales to determine which better identifies the spatial variability of soil phosphorus (P) within three low relief agricultural fields in central Illinois and to compare how two methods …

Electric Current: Siting A Wind Farm Off The Coast Of Maine, Ryan S. Clemens

Atlas of Maine

Using ArcMap, I analyzed several operational factors that would lead to a successful wind farm off the coast of Maine. Through calculating Euclidean distances and reclassifying the distances to fit within a 10-point scoring system, much of the coastline is viable for a potential wind farm. However, the most suitable area is a 115 square mile location 8 miles off the coast of Lincoln and Cumberland counties.

As huts are routinely burned down during attacks on a village, particularly in Sudan, the number of huts and villages burned can be used to corroborate on-the-ground reports.

Methods: Three remote sensing methods (Supervised Classification, Change Detection, and Feature Extraction) were performed on imagery from both before the attacks in February 2006 and after the attacks to examine any useful trends that could be …

Anthropology And Gis: Temporal And Spatial Distribution Of The Philippine Negrito Groups, Sabino G. Padilla Jr

Human Biology

The Philippine "negrito" groups comprise a diverse group of populations speaking over 30 different languages, who are spread all over the archipelago, mostly in marginal areas of Luzon Island in the north, the central Visayas islands, and Mindanao in the south. They exhibit physical characteristics that are different from more than 100 Philippine ethnolinguistic groups that are categorized as non-negritos. Given their numbers, it is not surprising that Philippine negritos make up a major category in a number of general ethnographic maps produced since the nineteenth century. Reports from various ethnological surveys during this period, however, have further enriched our …

A Comparison Of Recreational- And Intermediate Survey-Grade Gps Units For Importing Data Into Gis Software Packages, Tyler A. Brown, Lawrence R. Gering, Thomas J. Straka

The Journal of Extension

Global positioning systems (GPS) and Geographic Information Systems (GIS) have become common tools for Extension professionals. These systems vary in terms of accuracy and cost. GPS ranges from recreational-quality to survey-quality, with intermediate levels in between. As the user moves from recreational-quality to survey-quality, both accuracy and cost increase. We compare a recreational GPS unit (Garmin) and importing data into Google Earth software and an intermediate survey-grade GPS unit (Trimble Juno) and importing data into ArcMap GIS software. These represent two of the most common GIS choices available to natural resource professionals. Cost effectiveness will depend on accuracy requirements.

Winter Habitat Use By Juvenile Greater Sage-Grouse On Parker Mountain, Utah: Implications For Sagebrush Management, Danny Caudill, Terry A. Messmer, Brent Bibles, Michael R. Guttery

Human–Wildlife Interactions

Greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) are entirely dependent on sagebrush (Artemisia spp.) for food and cover during winter. Loss or fragmentation of important wintering areas could have a disproportionate affect on population size. We radio-marked and monitored 91 juvenile sage-grouse in south-central Utah from 2008 to 2010. Thirty-four individuals survived to winter (January to March) and were used to evaluate winter habitat use. Resource use was calculated using kernel density estimation of radio-marked individuals and compared to available habitat using a G-test. We found that juvenile sage-grouse used winter habitats characterized by 0 to 5% slopes …

The Influence Of Landscape Variation On Landform Categorization, Maia Williams, Werner Kuhn, Marco Painho

Journal of Spatial Information Science

This paper compares the landform vocabularies of residents from two regions in Portugal. Participants described both their own and the other less familiar landscapes in response to video footage of the regions. The results indicate that participants used more detailed vocabularies to describe the known landscape compared to the less familiar study site with detail triggered by individual place recognition. A relationship between landform lexica content and landscape type was observed in the relative placement of detail within each vocabulary. The observed drivers of categorization were the salient features of the landscape (elevation and land cover) and utilitarian motivations (land …

5d: A Gis-Based Approach For Determining And Displaying The Degree Of Operational Difficulty Of Demining, Pierre Lacroix, Rocío Escobar
