Current mechanisms for adopting and supporting high-tech augmentative alternative communication (AAC) within special-education appear limited in their success, despite recognition of the potential benefits they represent young emerging communicators. Prior research this field has been restricted to discrete survey or interview methodologies. We present a five-month mixed-methods ethnographic st...

In this paper some of the aspects of implementing measures for quality assurance of e-learning in developing countries are discussed. Also the main problems of establishing quality assurance of e-learning are illustrated. The advantages of adopting international measures of quality assurance in those countries together with several recommendations for the future and our conclusion are then given.

Rare Λb → Λl+l− decay is investigated in framework of general two Higgs doublet model, in which a new source of CP violation exists (model III). The polarization parameter, CP asymmetry and decay width are calculated. It is shown that CP asymmetry is a very sensitive tool for establishing model III. e-mail: [email protected] e-mail: [email protected]
