We analyze the scientific discourse of researchers in a specialty field in Astronomy by examining the influence that geographic location may have on the development of this field. Using as case study, the Sloan Digital Sky Survey (SDSS) project, we analyzed texts from bibliographic records along three geographic axes: US-only publications, non-US publications and international collaboration. Ea...

BACKGROUND The relationship between homicide and suicide has been studied extensively, but with conflicting results. The primary objective of this study was to examine the correlation between homicide and suicide rates in a large cross-sectional sample of UN member states. METHODS The study used age-standardized data on homicide and suicide for 65 international locales compiled by the World H...

The developments in Internet Mapping technology such as ArcIMS has leveraged to publish potential geographic and associated information through the Internet. To take advantage of this, an integrated Metadata/Data Server System has been designed and developed with an aim to provide a platform to share databases and metadata residing in ICIMOD and its GIS partners and stakeholders through the Int...

BACKGROUND Peritoneal dialysis is associated with similar survival and similar improvement in quality of life and is less costly compared with in-centre hemodialysis. We examined facility and geographic variation in the use of peritoneal dialysis in Canada. METHODS We analyzed data from the Canadian Organ Replacement Register for the period January 2001 to December 2010. We identified patient...

Many studies have indicated that ozone is associated with morbidity and mortality. A few studies have reported that the association is heterogeneous across seasons and geographic regions. However, little information is available on whether both temperature and geographic factors simultaneously modify the ozone effect. This study used a Poisson regression model to explore whether temperature mod...

Spatial processes are the focus of geography and should play a prominent role in geographic information systems (GIS). However, current GIS focus on the static description of properties in space and do not systematically support processes. A general method to describe spatial processes is a prerequisite to including processes in GIS software. This paper outlines an attempt to a general and appl...

The increasing use of geographic search engines manifests the interest of Internet users in geo-located resources and, in general, in geographic information. This has emphasized the importance of the development of efficient indexes over large geographic databases. The most common simplification of geographic objects used for indexing purposes is a two-dimensional rectangle. Furthermore, one of...
