Neighborhood Disparities In Stroke And Myocardial Infarction Mortality: A Gis And Spatial Scan Statistics Approach, Agricola Odoi
Neighborhood Disparities In Stroke And Myocardial Infarction Mortality: A Gis And Spatial Scan Statistics Approach, Agricola Odoi
Agricola Odoi
Background: Stroke and myocardial infarction (MI) are serious public health burdens in the US. These burdens vary by geographic location with the highest mortality risks reported in the southeastern US. While these disparities have been investigated at state and county levels, little is known regarding disparities in risk at lower levels of geography, such as neighborhoods. Therefore, the objective of this study was to investigate spatial patterns of stroke and MI mortality risks in the East Tennessee Appalachian Region so as to identify neighborhoods with the highest risks. Methods: Stroke and MI mortality data for the period 1999-2007, obtained free …
The Analysis Of Agricultural Landscape Change Using Gis Techniques. Case Study: Podoleni, Romania, Dan A. Chelaru, Adrian Ursu, Florin C. Mihai
The Analysis Of Agricultural Landscape Change Using Gis Techniques. Case Study: Podoleni, Romania, Dan A. Chelaru, Adrian Ursu, Florin C. Mihai

The increasingly tensions rising between society’s need for resources and space on the one hand, and the capacity of the land to support these needs on the other hand lead to unprecedented changes in landscape configuration, and hence, to the environment. This paper analyzes changes in the agricultural landscape of Podoleni, Neamt County, Romania, in spatio - temporal terms, as a result of the modernization of the ground processing techniques, types of crops, and the degree of fragmentation of land parcels. The study was conducted using Geographical Information Systems techniques, the main materials used in the analysis are topographic maps …

This paper reports new data on qocha ponds from the Rio PucaraeAzángaro interfluvial zone, northern Lake Titicaca Basin, Peru. Qocha are a little known form of Andean agriculture that developed around 800e500 B.C. and remain in use today. Prior estimates suggested that in the study area, there were more than 25,000 qocha. While most Andean sunken beds are excavated to reach groundwater, qocha are rain- fed ponds. How these rain-fed ponds functioned has been an open question, but one that is answered in part by research presented in this paper.We suggest that a thick impermeable stratum of clay that was …

Ground Truthing Of Remotely Identified Fortifications On The Central Coast Of Perú, Margaret Brown Vega, Nathan M. Craig, Gerbert Asencios Lindo

Remote imagery, including freely available satellite images viewed in Google Earth_ and historic aerial photographs, was used to identify anomalies in a 25,000 km2 macroregion encompassing 13 river valleys along the Peruvian coast. These anomalies, located atop hills and mountains, were hypothesized prehispanic fortifications. A sample of remotely identified anomalies was ground truthed in the Huaura and Fortaleza Valleys on the Central Coast of Perú. 140 positive anomalies were documented and assessed using a simple defensibility index. Our results significantly increase the number of fortifications identified in both valleys. We demonstrate the efficacy of this method for locating fortifications in …

Dr. Dipo Theophilus Akomolafe MBCS, MNCS, MCPN,
The reconnaissance soil fertility study of 10,000 ha partly encroached forest reserve located between latitude 11°47’N and 11°56’N and longitude 4°22’E and 4°32’E in Northern Nigeria was conducted in 2009 to generate a soil fertility data base of the reserve. The tracking of the forest reserve boundary was done using a Garmin 72 model global positioning system (GPS) receiver. The geographic coordinates were input into the computer to generate a digital map of the forest reserve. The entire forest reserve was divided into grids to guide in the location for soil sampling using the GPS/Geographic Information System (GIS) geospatial technique. …

Advancing Theory?: Landscape Archaeology And Geographical Information Systems, Di Hu

This paper will focus on how Geographical Information Systems (GIS) have been applied in Landscape Archaeology from the late 1980s to the present. GIS, a tool for organising and analysing spatial information, has exploded in popularity, but we still lack a systematic overview of how it has contributed to archaeological theory, specifically Landscape Archaeology. This paper will examine whether and how GIS has advanced archaeological theory through a historical review of its application in archaeology.
