In our discussions with end users about today's vi-sualization environments we were led to consider new concepts for the setting up of a platform which should be better suited to their real needs. In this paper, a hierarchy of visualization objects is presented. They will be the main elements of an new platform which should be both intuitive and extensible.

This review focuses on how blood flow to contracting skeletal muscles is regulated during exercise in humans. The idea is that blood flow to the contracting muscles links oxygen in the atmosphere with the contracting muscles where it is consumed. In this context, we take a top down approach and review the basics of oxygen consumption at rest and during exercise in humans, how these values chang...

In a Step-down procedure, apart from an hierarchy of the component hypotheses (leading to the steps), one also needs to settle on, their individual levels of significnace (constrained on the overall one). The Fisher method of combining independent tests is extended to the step-down procedure and its Bahadur-efficiency and (asymptotic) optimality results are considered.

Dimension hierarchies represent a substantial part of the data warehouse model. Indeed they allow decision makers to examine data at different levels of detail with On-Line Analytical Processing (OLAP) operators such as drill-down and roll-up. The granularity levels which compose a dimension hierarchy are usually fixed during the design step of the data warehouse, according to the identified an...

The philosophy and effect of Anarchy is that of a boundless and striking one. Anarchy in society bears the ability to tear at the seams of its structure and bring humanity down to its very basic needs. Anarchy dissolves political power and government, and can leave authority or even hegemony in the hands of the dominant human. It is true to be said, (as I quote Eric Schmidt, former chief execut...

BACKGROUND Health care is a complex sociotechnical system. Patient treatment is evolving and needs to incorporate the use of technology and new patient-centered treatment paradigms. Cognitive work analysis (CWA) is an effective framework for understanding complex systems, and work domain analysis (WDA) is useful for understanding complex ecologies. Although previous applications of CWA have des...

AIM This paper applies Maslow's Hierarchy of Needs Model to the challenges of understanding and motivating employees in a rapidly changing health care industry. BACKGROUND The perspective that Maslow's Model brings is an essential element that should be considered as the health care arena is faced with reorganization, re-engineering, mergers, acquisitions, increases in learning demands, and t...
