No thematic map is perfect. Some pixels or polygons are not accurately classified, no matter how well the map is crafted. Therefore, thematic maps need metadata that sufficiently characterize the nature and degree of these imperfections. To decision-makers, an accuracy assessment helps judge the risks of using imperfect geospatial data. To analysts, an accuracy assessment helps describe the rel...

background and objective: obstructive sleep apnea (osa) is the most common type of sleep-disordered breathing. multivariable apnea prediction (map) index consists of three questions about the frequency of osa symptoms plus body mass index (bmi), age and sex that categorizes the patients to low and high risk for osa using a formula. objective map index was calculated by discounting the questions...

Maps are powerful tools used to analyze and compare a wide range of geographically referenced data. The last third of the twentieth century has witnessed the increasing use of maps to portray statistical information. Maps of mortality and morbidity are useful for assessing relationships with potential risk factors. They can also be used to track progress in public health programs and policy dev...

Wildland fires are a function of properties of the fuels that sustain them. These fuels are themselves a function of vegetation, and share the complexity and dynamics of natural systems. Worldwide, the requirement for solutions to the threat of fire to human values has resulted in the development of systems for predicting fire behaviour. To date, regional differences in vegetation and independe...

For the precaution against physical soil degradation in managed soils, accurate planning data about anthropogenic impacts and for policy making applicable indicators to describe the driving force and state are required. To assess the potential erosion risk, accurate information is available, but to assess the actual erosion risk it is necessary to regard current land-use and cultivation data fo...

This paper describes a qualitative research project involving a case study that was analyzed using grounded theory and cognitive mapping. It contributes to a theory that describes the impact of enterprise resource planning (ERP) on organizational knowledge. ERP systems produce effects that make business knowledge become more focused or “convergent” from the perspective of the organization and m...

The paper summarizes the results of a large European project on the critical risk factors for Power-Two-Wheeler (PTW) safety. Analyses conducted in both a macroscopic and microscopic level in Greece, Spain, Italy, Great Britain, Austria, Finland and Germany revealed a set of critical risk factors as well as their ranking of importance. Among the research questions treated are what are the most ...
