Participation and cognitive quality profiles in an online discussion forum

Abstract: A JOUR study was used to analyse the relationships between participation in an online discussion forum and the cognitive quality of the contributions made. Participation was calculated using two dimensions: presence (who accesses the environment, how often and for how long) and connectivity (who interacts with whom and the degree of intensity of the interaction). The discussion forum considered forms part of a course on Educational Psychology included in the curriculum of initial teacher training at the University of Barcelona and was accessed by 17 students over a period of 25 days. The analysis was carried out using a multi-method approach, which combines quantitative indicators of presence and connectivity with a content analysis of the contributions made by each participant. The results suggest that a high level of participation (high level of presence/high level of connectivity) is a necessary but not a sufficient condition for maintaining high-quality contributions throughout the discussion.

Towards a generic platform for developing CSCL applications using Grid infrastructure

Abstract: The goal of this paper is to explore the possibility of using CSCL component-based software under a Grid infrastructure. The merge of these technologies represents an attractive, but probably quite laborious enterprise if we consider not only the benefits but also the barriers that we have to overcome. This work presents an attempt toward this direction by developing a generic platform of CSCL components and discussing the advantages that we could obtain if we adapted it to the Grid. We then propose a means that could make this adjustment possible due to the high degree of genericity that our library component is endowed with by being based on the generic programming paradigm. Finally, an application of our library is proposed both for validating the adequacy of the platform which it is based on and for indicating the possibilities gained by using it under the Grid.

Standardized low-power wireless communication technologies for distributed sensing applications.

Abstract: Recent standardization efforts on low-power wireless communication technologies, including time-slotted channel hopping (TSCH) and DASH7 Alliance Mode (D7AM), are starting to change industrial sensing applications, enabling networks to scale up to thousands of nodes whilst achieving high reliability. Past technologies, such as ZigBee, rooted in IEEE 802.15.4, and ISO 18000-7, rooted in frame-slotted ALOHA (FSA), are based on contention medium access control (MAC) layers and have very poor performance in dense networks, thus preventing the Internet of Things (IoT) paradigm from really taking off. Industrial sensing applications, such as those being deployed in oil refineries, have stringent requirements on data reliability and are being built using new standards. Despite the benefits of these new technologies, industrial shifts are not happening due to the enormous technology development and adoption costs and the fact that new standards are not well-known and completely understood. In this article, we provide a deep analysis of TSCH and D7AM, outlining operational and implementation details with the aim of facilitating the adoption of these technologies to sensor application developers.
