The goal of PLANT is to facilitate individual learning on the Internet which abounds in a wide variety of educational resources and services. The distinctive features of PLANT are threefold. First, multifarious educational contents as well...

We show that decimation transformations applied to high-q Potts models result in non-Gibbsian measures even for temperatures higher than the transition temperature. We also show that majority transformations applied to the Ising model in a very strong eld at low temperatures produce non-Gibbsian measures. This shows that pathological behavior of renormalization-group transformations is even mor...

The purpose of this study was to describe the experiences of general education teachers who have had a student with severe disabilities in their class. Interviews of 19 general education teachers, kindergarten through Grade 9, as well as questionnaires completed by 18 teachers, were analyzed using categorical coding procedures to identify themes related to the teachers' experiences.

Hypermedia links describe purposeful relationships between contents, and in consequence, their semantic intention can been modelled by the notion of link type. Ontologies can be used to extend that notion of link type, eventually resulting in shared conceptualizations useful to achieve consistent linking practices. In addition, the relationship embodied by the link is in many cases inherently i...

Experimental investigations of the neural substrate of consciousness typically take one of two paths, studying (1) contents or (2) levels of consciousness. It seems obvious to most that these two "paths" are interrelated, yet much less obvious how. This paper gives one suggestion to grasp the interrelation, arguing that conscious levels are determined by conscious contents in a very specific wa...
