The aim of the contribution is to present a novel systematic model of interaction analysis which was designed and successfully experimented with a wide sample of adult learners in order to enhance and understand cognitive, socio-organizational and emotional-affective processes of virtual learning communities (VLCs). Starting from strengths and weaknesses of the present models and methodologies ...

The purpose of this article is to propose a methodological approach to analyse how the positioning of actors in an interorganisational network can influence the elements of value creation. This study fills a gap in the existing literature by exploring the relationship between the positioning of actors and the value creation in a context of interorganisational networks. The case study method was...

This article discusses how groups of student teachers use the wiki to collaborate cross-institutionally in order to design tasks for English language learners. Participants in this case study involved student teachers at a private graduate institution on the East Coast in the U.S. and students at a public graduate institution in Luxembourg. In this action research approach, data triangulation i...

This study investigated the research trends in language learning in a virtual reality environment by conducting a content analysis of findings published in the literature from 2004 to 2013 in four top ranked computer-assisted language learning journals: Language Learning & Technology, CALICO Journal, Computer Assisted Language Learning, and ReCALL. Data from 29 articles were cross-analyzed in t...

We consider the following problem given a pla nar straight line graph nd a covering triangulation whose maximum angle is as small as possible A cov ering triangulation is a triangulation whose vertex set contains the input vertex set and whose edge set con tains the input edge set The covering triangulation problem di ers from the usual Steiner triangulation problem in that we may not add a ver...

In this paper a dynamic image representation is proposed by combining advantages of both raster and vector graphics in the triangulation. In order for a dynamic mesh to remain a triangulation, a method which maintains integrity of representation is devised. Together with techniques for synthesizing paint, the end result is a configurable scheme demonstrating potential as a viable alternative fo...

This article examines the relationship between training, competence and performance of small and mediumsized enterprises (SMEs) in the context of e-business.
