  2010 MAR 2 - (VerticalNews.com) -- According to a study from Dublin, Ireland, "An ultrametric topology formalizes the notion of hierarchical structure. An ultrametric embedding, referred to here as ultrametricity, is implied by a hierarchical embedding."

  "Such hierarchical structure can be global in the data set, or local. By quantifying extent or degree of ultrametricity in a data set, we show that ultrametricity becomes pervasive as dimensionality and/or spatial sparsity increases. This leads us to assert that very high dimensional data are of simple structure. We exemplify this finding through a range of simulated data cases," wrote F. Murtagh and colleagues ...read more

  2010 FEB 23 - (VerticalNews.com) -- According to recent research from the United States, "Agency theory offers a foundation for explaining the impact of project monitoring on project success. This study applied agency theory to survey 428 information systems project managers concerning their project monitoring, shirking by systems developers, and project success."

  "Greater project monitoring via planning and meetings predicted less shirking, while greater monitoring via responsibilities and comparison did not. Less shirking via poor focus predicted increased project success, while less shirking via loafing did not," wrote R.C. Mahaney and colleagues, Eastern Kentucky University ...read more

  2010 FEB 9 - (VerticalNews.com) -- "In Guatemala, where statistics and information systems do not yet play a central role in planning and decision-making processes, a USAID-funded project was initiated in 2007 to systematically collect data and information for the education component of the social sector," scientists in Guatemala report.

  "The project utilizes up-to-date business intelligence tools and software for gathering, storing, analyzing, and providing access to data. The primary outcome of the intervention has been the development of the National Integrated Information System, an online accessible platform that includes all information from the social sector (i.e. education, health, finance and population)," wrote C. Perezbrito and colleagues ...read more
