Impaired electrical conduction has been shown to play an important role in the development of heart rhythm disorders. Being able determine conductivity is localize arrhythmogenic substrate that causes abnormalities atrial tissue. In this work, we present algorithm estimate from epicardial electrograms (EGMs) using a high-resolution electrode array. With these arrays, it possible measure propaga...

For any such use of scale scores, there is a critical assumption that the scale is measuring the same trait in all of the groups. If that assumption holds, then comparisons and analyses of those scores are acceptable and yield meaningful interpretations. But if that assumption is not true, then such comparisons and analyses do not yield meaningful results. This is the general issue of (MI). mea...

This research examined the validity of the Performance Environment Perception Scales (PEPS), a new instrument designed to assess performance-relevant aspects of the work environment. A sample of 156 employees of an Australian university completed the PEPS and their supervisors rated their task and citizenship performance. Confirmatory Factor Analysis showed the PEPS to have a valid factor struc...

This article explored the effect of resource-based capability and inter-organizational coordination on a firm’s supply chain management focus. We proposed a conceptual framework to describe these two sets of antecedents. The hypotheses were tested using confirmatory factor analysis and multiple linear regression on a set of data collected in the U.S., Europe, and New Zealand. Test results revea...
