Script Theory of Guidance 1 Running head: SCRIPT THEORY OF GUIDANCE Toward a Script Theory of Guidance in Computer-Supported Collaborative Learning

This article presents an outline of a script theory of guidance for computer-supported collaborative learning (CSCL). With its four types of components of internal and external scripts (play, scene, role, and scriptlet) and seven principles, this theory addresses the question how CSCL practices are shaped by dynamically re-configured internal collaboration scripts of the participating learners....

Scattering Theory: Born Series

Is Just War Theory Obsolete?

Just War Theory can be found in almost all major cultures. But since war was a business that could not be easily stopped, some aimed to constrain it. In its classic form, Just War Theory has been around for several centuries—ever since nationhood in Europe replaced provincial governments. Having made some introductory considerations, I will ask: should Just War Theory be left as it is, changed,...

Self-dual Born-Infeld Theory

We study the supersymmetric extension of the gauged O(3) sigma model in 2+1 dimensions and find the supersymmetry algebra. We also discuss soliton solutions in case the Maxwell term is replaced by the Born-Infeld term. We show that by appropriate choice of the potential, the self-dual equations in the Born-Infeld case coincide with those of the Maxwell’s case.

Comments on Born–Infeld Theory

The low-energy effective action of supersymmetric D-brane systems consists of two terms, one of which is of the Born–Infeld type and one of which is of the Chern–Simons type. I briefly review the status of our understanding of these terms for both the Abelian and non-Abelian cases. Talk presented at Strings 2001 1 Single BPS D-Brane D-branes are surfaces on which open strings can end [1] [2] [3...
