We shed new light on the long-debated question about the nature of mental images, that is, the underlying structures and processes, with a new theory of mental imagery. This theory is formalized as a computational cognitive model and provides an integrated account of the three prevalent theories of mental imagery, i.e., the descriptive, the quasi-pictorial, and the enactive theory. It does so b...

An experiment is reported which tests whether network information is more effectively displayed in a three dimensional space than in a two dimensional space. The experimental task is to trace a path in a network and the experiment is carried out in 2 0 , in a 3 0 stereo view, in a 3 0 view with head coupled perspective, and in a 3 0 stereo view with head coupled perspective: this last condition...

A trading partner agreement can be used to regulate the cooperation of organizations. It is typically written in natural language which gives rise to misunderstandings when partners interpret it differently. In addition it is often compiled in an unsystematic way so that we might easily overlook a situation the contract should have covered. It is therefore desirable to have a method that can su...

Introduction: The basic needs of a patient and his/her family members are to be supported during health care and especially during critical situations. One such support is required during cardiopulmonary resuscitation (CPR).Hence knowing the perspective of medical persons about “Family member’s Presence during Resuscitation” (FPDR) in the Intensive Care Unit (ICU) is important...

The current state-of-the-art in electronic negotiations shows a focus on the trade of standardised mostly inexpensive products in fixed networks of suppliers and customers. To overcome these shortcomings, the goal must be to enable the trade of complex and valuable goods and to support many-to-many marketplace for that purpose. Once valuable goods are concerned, the trade process involves negot...

Modeling how we choose among alternatives, or more generally, modeling preferences, is one of the core topics of study in Psychology. Preferences can be studied experimentally using a variety of procedures, one of the oldest being the method of paired comparisons. This method remains quite popular in areas such as psychophysics and consumer psychology. For a good overview of the method of paire...

The perspective-N-point problem is a well known issue in computer vision. It consists in the determination of the distance between the camera and a set of points well known in an object coordinate space. This problem has been extensively treated in the literature and is still opened. Many solutions already exist. All these approaches consider only common planar camera. We propose, with a new fo...

This paper presents some key concepts and underlying assumptions of three current fields of research: the Theory of Organized Activity, Organizational Semiotics and Language Action Perspective. All these fields are related by a human/social/organizational common view of Information Systems. In our analysis and, within Organizational Semiotics field Ronald Stamper’s theory was chosen, while with...
