Some solutions, some problems, and some questions

A. Willsky
1982 Control Systems Magazine  
This is a slightly expanded written version of a plenary lecture given at the 20th IEEE Conference on Decision and Control, December 1981, San Diego, Calif.  ...  One such direction, model-based signal processing, is treated in some depth together with an example, an object detection and estimation approach to tomographic reconstruction.  ...  The perspective of AI is aimed directly at attacking and breaking down problems of enormous complexity into smaller problems, On the other hand, the perspective in control, estimation, decision, and system  ...

On the Difference or Equality of Information, Misinformation, and Disinformation: A Critical Research Perspective

Bernd Carsten Stahl
2006 Informing Science  
More and better information is often seen as a prerequisite for better management practices. It is the task of information systems to collect or create such information.  ...  This paper discusses the notion of information as well as the apparently opposing notions of misinformation and disinformation from a critical research perspective.  ...  Having thus outlined the concept of information and some of its problems, the paper will give an overview of critical research in information systems.  ...

Why different people prefer different systems for different tasks: An activity perspective on technology adoption in a dynamic user environment

Jun Sun
2011 Journal of the American Society for Information Science and Technology  
The findings provide insights on how to enhance technology adoption by tailoring system development and management to various task contexts and different user groups.  ...  Based on the premises of Activity Theory, this study examines how user characteristics, system experiences, and task situations influence an individual's preferences among different systems in terms of  ...  That is, user preference among different systems can depend largely on which ones have been more helpful for solving problems than have been others.  ...

E-BioFlow: Different Perspectives on Scientific Workflows [chapter]

Ingo Wassink, Han Rauwerda, Paul van der Vet, Timo Breit, Anton Nijholt
2008 Communications in Computer and Information Science  
Each perspective provides its own type of information, visualisation and support for validation.  ...  All three perspectives are of equal importance, but workflow designers from different domains prefer different perspectives as entry points for their design, and a single workflow designer may prefer different  ...  Instead of being only applicable to a specific problem, workflow models designed using e-BioFlow become a general solution for a group of problems, independent of specific resources.  ...
