Background: The International Sensitivity Index (ISI) calibration of whole-blood prothrombin time (PT) monitors for point-of-care testing (POCT) described by Tripodi et al. (Thromb Haemost 1993;70:921–4) has been shown to be dependable but is too complex and demanding. The use of plasma would simplify calibration of whole-blood POCT PT monitors, but important differences may exist between the I...

Individuals with schizophre...

Information systems infrastructure (ISI) was ranked as the most important issue in a 1994-1995 study of key issues in IS management (Brancheau et al. 1996). Yet, to date, little theoretical and empirical work has been done in this area. This study attempts to reconceptualize the ISI construct and its measures. Drawing from the literature, this study envisions ISI as a base of shared technologic...
