A Qualitative Approach to E-Learning ? A Dynamic Situation in Montpellier Business School

The article proposes a more productive way and approach for an e-learning research methodology. The e-learning tools: the computer and the Internet are serious obstacles for sense making in the student’s behaviour context. Their use defines in a way the user’s behaviour. This article underlines the advantages of qualitative methods for this kind of research and vote for an ethnographic method. Our suggestion has many assets in order to understand and consider interactions. Communication processes tend to have a strong influence on learning behaviour and are almost neglected during quantitative methodology. Accurate and corrective feedback is essential for establishing and performing elearning techniques. Our suggestions are highlighted by lessons learnt from Montpellier Business school experience

Overview and Analysis of Practices with Open Educational Resources in Adult Education in Europe

OER4Adults aimed to provide an overview of Open Educational Practices in adult learning in Europe, identifying enablers and barriers to successful implementation of practices with OER. The project was conducted in 2012-2013 by a team from the Caledonian Academy, Glasgow Caledonian University, funded by The Institute for Prospective Technological Studies (IPTS). The project drew on data from four main sources: • OER4Adults inventory of over 150 OER initiatives relevant to adult learning in Europe • Responses from the leaders of 36 OER initiatives to a detailed SWOT survey • Responses from 89 lifelong learners and adult educators to a short poll • The Vision Papers on Open Education 2030: Lifelong Learning published by IPTS Interpretation was informed by interviews with OER and adult education experts, discussion at the IPTS Foresight Workshop on Open Education and Lifelong Learning 2030, and evaluation of the UKOER programme. Analysis revealed 6 tensions that drive developing practices around OER in adult learning as well 6 summary recommendations for the further development of such practices

Tweetstorming PLNs: Using Twitter to Brainstorm about Personal Learning Networks

Sie, R., Boursinou, E., Rajagopal, K., & Pataraia, N. (2011). Tweetstorming PLNs: Using Twitter to Brainstorm about Personal Learning Networks. In Proceedings of The PLE Conference 2011. July, 10-12, 2011, Southampton, UK.We start off by giving a short introduction. The introduction defines the scope of the workshop, the purpose, and the means. Particularly, the participants will be asked to identify their personal online learning network. They should identify how they are connected to others (Twitter, LinkedIn, Facebook, offline), and what they think their peers’ expertises are. This will provide us with an elaborate view on how participants perceive their learning network. Next, the Tweetstorm (brainstorm over Twitter) will be introduced and explained. During the Tweetstorm, we discuss what contributes to meaningful cooperation within a learning network. A twitter hashtag (#usePLN) will be used to monitor and aggregate the participants’ utterances. A ‘Twitter wall’ (hashtags.org) will be used to visualise the brainstorm, such that participants see what others have posted, building upon their ideas and reacting to their ideas. Finally, we collect the results and conclude our session with an overview of the learning network and the outcomes of the Tweetstorm session

Measurements and Investigation of Phenomena in Low Voltage Fuses

167 σ.Κατά το σχεδιασμό οποιασδήποτε ηλεκτρολογικής εγκατάστασης, ξεχωριστή θέση λαμβάνει ο σχεδιασμός της προστασίας της. Απαραίτητα μέσα προστασίας είναι οι ασφάλειες. Οι ασφάλειες προστατεύουν τα κυκλώματα από υπερφορτίσεις εξαιτίας βραχυκυκλωμάτων ή άλλων σφαλμάτων και έτσι αποσοβούν υλικές ζημιές ή ακόμη και ηλεκτροπληξίες ή πυρκαγιές. Η επιλογή των κατάλληλων για κάθε ηλεκτρολογική εγκατάσταση ασφαλειών εξαρτάται από την τάση λειτουργίας του κυκλώματος (χαμηλή ή υψηλή τάση) και την εκάστοτε εφαρμογή. Ακόμη, υπάρχουν διάφοροι τύποι ασφαλειών που καθορίζονται από τον τρόπο κατασκευής τους και εξυπηρετούν διαφορετικές ανάγκες. Εθνικοί και διεθνείς οργανισμοί έχουν συντάξει κανονισμούς και τυποποιήσεις στους οποίους ορίζονται ο τρόπος κατασκευής, τα βασικά χαρακτηριστικά και οι απαραίτητες δοκιμές για τις ασφάλειες. Η μελέτη των διατάξεων των ασφαλειών είναι εξαιρετικά σημαντική για τη διασφάλιση της σωστής λειτουργίας του συστήματος. Οι διατάξεις αυτές ως στοιχεία του κυκλώματος υπόκεινται σε αύξηση της θερμοκρασίας τους και πιθανές υπερθερμάνσεις, όπως επίσης παρουσιάζουν θερμικές απώλειες οι οποίες συνεπάγονται καταναλισκόμενη ενέργεια. Στην παρούσα μελέτη διενεργήθηκαν πειράματα σε ένα κύκλωμα προσομοίωσης που περιελάμβανε μια μαχαιρωτή ασφάλεια, μία ασφαλειοθήκη και καλώδια που συνέδεαν τη διάταξη με ένα σύστημα τροφοδοσίας. Για τη διερεύνηση των φαινομένων στις ασφάλειες χαμηλής τάσης πραγματοποιήθηκαν δοκιμές σε μαχαιρωτές ασφάλειες διαφόρων ονομαστικών ρευμάτων, οι οποίες τοποθετήθηκαν σε ασφαλειοθήκες δύο διαφορετικών ονομαστικών ρευμάτων. Για τη μελέτη της θερμοκρασίας της ασφάλειας χρησιμοποιήθηκαν δύο καταγραφικά μέσα, μια θερμοκάμερα και ένα ψηφιακό καταγραφικό μηχάνημα. Ακόμη, στα άκρα της διάταξης παρέμενε συνδεδεμένο ένα βολτόμετρο, η ένδειξη του οποίου βοήθησε στον υπολογισμό της καταναλισκόμενης ενέργειας. Μετά την επεξεργασία των μετρήσεων, η παρούσα εργασία ανέλυσε την αξιοπιστία των δύο καταγραφικών μέσων που χρησιμοποιήθηκαν και αποτιμήθηκε η σημασία της καταναλισκόμενης ενέργειας της διάταξης. Αφού προτάθηκαν κάποιοι τρόποι ελαχιστοποίησης της καταναλισκόμενης ενέργειας, όπως για παράδειγμα η χρήση ασφαλειοθήκης μεγαλύτερου ονομαστικού ρεύματος, διερευνήθηκε και εκτιμήθηκε η αντίστοιχη μείωση κόστους που θα μπορούσε να επιτευχθεί.The design of the protection system for an electrical installation plays a role of great importance in the overall design of the latter. Fuses are essential means of such protection systems. Fuses protect the circuits from over-loadings due to short-circuits and other faulty conditions and in this way, they eliminate the risk of damages, electrocutions or even fires. The choice of the appropriate fuse for an electrical installation depends on the system’s voltage (low or high voltage) and the application for which the fuse will be used. In addition, there are different types of fuses characterised by the way they are produced and the needs that they cover. National and International organizations have written specifications, which fuses and the associated equipment should be compliant with concerning the way of their production, their core characteristics and the necessary tests for the verification of the fuses. Studying fuses’ installations is very significant so as someone to reassure that a system operates in the right way. Fuses, being parts of the circuit, experience temperature increase and also, are responsible for –even small- power losses and consequently power dissipation. During the current study experiments were held using a simulating circuit which consisted of an NH type fuse, a fuse-holder and cables to connect the fuse installation with a power supply system. So as to study the phenomena of the low voltage fuses the experiments were repeated for NH type fuses of various rated currents that were placed in fuse-holders of two different rated currents. Two devices, a thermocamera and a digital recording device were used to report the temperature of the fuse installation. Also, a voltmeter was steadily connected to the terminals of the fuse installation, from which the voltage values were picked up and then used for the calculation of the power dissipation. After processing the results derived by the experiments, the current study judged the reliability of the recording devices used and assessed the significance of the power dissipation on the fuse installation. Finally, after the suggestion of some ways of minimising the power dissipation, like for example the use of higher current-rated fuse-holders, the practical reduction in cost was appraised.Eλένη Π.

Narrating your work: an approach to supporting knowledge sharing in virtual teams

We propose an approach to enhancing knowledge sharing and connectedness in distributed teams. Termed ‘Narrating Your Work’ (NYW), the approach involves members of distributed team using a microblogging tool to post regular updates about their current work, accomplishments, and issues. The NYW approach was evaluated within a geographically and temporally distributed team at Shell International for a period of one month, using a mixed-method research design. Methodology comprised of a quantitative survey, followed by semi-structured interviews and analysis of microblogging updates posted during the month in which the approach was being trialled. The evaluation results suggest that NYW was viewed as a valid and practical approach to enhancing knowledge sharing and connectedness. A range of barriers and enablers that could impact the future application and embedding of the approach are identified and recommendations for implementation are outlined
