This paper argues that for the study and facilitation of collaborative learning, existing theories of grounding such as that of Clark and Shaefer [5] cannot be applied without adjustments. When comparing collaborative learning and conversation, four dimens ...
Most of the efforts concerning graphical representations of humans (Virtual Humans) have been focused on synthesizing geometry for static or animated shapes. The next step is to consider a human body not only as a 3D shape, but as an active semantic entity ...
The learning center concept is based on a new vision centered on the need for a convergence of human, information, knowledge, educational resources and a relevant part of information and collaborative technologies. This vision is founded on the new student ...
With an ever-increasing understanding of the brain mechanisms associated with core human attributes and values, there is an increasing public interest in the results of neuroscience research and the ways in which that new knowledge will be used. Here, we p ...
The revolution in information technology transforms not only information and its uses but, more important, knowledge and the ways we generate and manage it. Knowledge is now seen as input, output, and capital, even if imperfectly accounted for or understoo ...
The processing and characterization of electrical properties of potassium niobate ceramic, KNbO3 (KN) have been studied. The difficulty of obtaining dense samples by conventional methods limits the knowledge on electrical properties of this material. In th ...
The search for external knowledge must necessarily be accompanied by effective organizational learning. The effectiveness of learning is dependent on quite dissimilar factors based on whether the learning objective is explorative or exploitative. Moreover, ...
New knowledge with commercial potential is continually created in academic institutions. How is it turned into economically valuable businesses? This paper argues that the transfer is an entrepreneurial process. To understand this, the actions and the cons ...
The present paper reviews existing knowledge with regard to Organic Aerosol (OA) of importance for global climate modelling and defines critical gaps needed to reduce the involved uncertainties. All pieces required for the representation of OA in a global ...
Under gas evolution, the current voltage characteristics of an electrochemical cell are strongly affected by the presence of growing bubbles. At high current densities, the evolution of the bubbles becomes the rate limiting step of the electrochemical proc ...
