Female breast, colorectal, and cervical cancer are three common cancers among people in the United States. Both their incidence and mortality rates can be dramatically reduced if effective prevention and intervention programs are developed and implemented, because these cancers are preventable through regular screenings. American Indians in the United States especially in the Northern Plains ha...

In this paper, we extend previous work on geographic random forwarding (GeRaF) by considering a more efficient paradigm whereby on/off cycles are exploited and every node can participate to packet relaying, as long as it wakes up during any handshake procedure. The protocol is fully distributed, as routing decisions are made hop by hop based on geographic metrics and using a joint channel acces...

There is much ongoing research about the effect of the urban environment as compared with individual behaviour on growing obesity levels, including food environment, settlement patterns (e.g., sprawl, walkability, commuting patterns), and activity access. This paper considers obesity variations between US counties, and delineates the main dimensions of geographic variation in obesity between co...

Nowadays, information systems (IS) use the Internet/Intranet as their natural operating environment. Internet/Intranet environment has introduced additional opportunities in the development and operation of information systems and sources of information they use. Information systems take advantage of multiple heterogeneous sources of information. Using information from different sources include...

The collection and dissemination of geographic information has long been the prerogative of national mapping agencies. Nowadays, location-aware mobile devices could potentially turn everyone into a mapmaker. Collaborative mapping is an initiative to collectively produce models of real-world locations online that people can then access and use to virtually annotate locations in space. This chapt...

OBJECTIVES In this study we examined geographic disparities in medical home access among US children with special health care needs (CSHCN) aged 0 to 17 years. METHODS The 2005-2006 National Survey of Children With Special Health Care Needs was used to estimate prevalence and odds of not having a medical home and 5 component outcomes according to state. Logistic regression was used to examine...

Geographic information fusion is the process of integrating geographic information from diverse sources to produce new information with added value, reliability, or usefulness (cf. [14,67]). Geographic information fusion is an important function of interoperable and web-based GIS. Increased reliance on distributed web-based access to geographic information is correspondingly increasing the need...
