"How Many Roads" n. 158 di Rassegna e Urbanistica
No full textCome recita l'editoriale di Maria Argenti "Rassegna si volge indietro a vedere la strada stavolta, quella percorsa e quella che abbiamo davanti, attraverso le orme del cammino, dei tanti cammini, che andiamo tracciando. Per dire una cosa soprattutto: che essi segnano la qualità della nostra vita urbana; che il tempo percorso a piedi nei tragitti cittadini è un tempo guadagnato alla bellezza di una relazione". Il numero raccoglie riflessioni e progetti sullo spazio della strada nella città contemporanea con scritti di: I. Aquilé, M. Argenti, C. Bianchetti, G. Canto Moniz, A. Capuano, G. Celestini, I. Cortesi, F. Di Carlo, B. Di Donato, A. Ferlenga, I. Ferreira, Gaeta & Springall, S. Rueda Palanzuela, F. Tonucci, A. Valeriani, P. Viganò, E. Roca, M. Sansica, F. Toppetti, C. Zucca
Standard e Sistemi di Certificazione per il Project Management
No full textQuella del Project Manager è una professione emergente nel campo dell’Information Technology e sempre più aziende scelgono di affidarsi a professionisti certificati capaci di applicare approcci e processi standard alla gestione dei progetti.

Ontologie OWL: Teoria e Pratica (prima parte)
No full textLe ontologie sono uno strumento sempre più diffuso tra gli sviluppatori Web per i vantaggi che offrono nella condivisione delle informazioni. In questo mini-corso di tre lezioni cercheremo, attraverso un approccio pragmatico basato su esempi, di introdurre il lettore alla realizzazione di ontologie ed al loro utilizzo nell’ambito di applicazioni Java. In questa prima puntata mostreremo in particolare come definire una semplice ontologia OWL, introducendo anche concetti elementari di modellazione della conoscenza
Application scenarios for a learning grid
No full textThis chapter analyses the adoption of the Learning Grid for the development of challenging Application Scenarios in the eLearning domain. The Application Scenarios described in this chapter create a breakthrough in current learning practices. Instead of adopting a traditional information transfer paradigm, the proposed scenarios, in fact, promote and support a learning paradigm centred on the learner and focused on knowledge construction using experiential based and collaborative learning approaches in a contextualised, personalised and ubiquitous way. The purpose of our analysis is to understand and argue about the potential advantages of adopting the Learning Grid for the proposed scenarios. Preliminary findings show that Learning Grid can be considered an enabling technology for the presented scenarios since its features (e.g. dynamicity, adaptiveness, support for Virtual Organisation creation and management, advanced mechanisms for resources and services discovery on the basis of Quality of Services) are key to improve personalisation and knowledge construction in the learning process as well as communication and collaboration inside learning groups
The anatomy of the learning grid
No full textOver the last few years, Technology Enhanced Learning (TEL) needs have been changing in accordance with ever more complex pedagogical models as well as with technological evolution, demanding for high dynamic and configurable environments for running multiple teaching and learning scenarios.. Grid technologies have started to be very popular even in education due to the advantages that they offer being based on a secure, flexible and coordinated way of sharing resources over Internet as well as on its enormous capability of information processing. A Grid may facilitate learning processes in allowing each learner to collaboratively use the resources already existing online, by facilitating and managing dynamic communication with other people and agents, through the implementation of dynamic Virtual Organizations allowing to share learning resources. Nevertheless, in order to be effectively used in TEL, Grid must be complemented with other technologies bringing to the concept of “Learning Grid” whose description is the object of this chapter
Knowledge-based assessment in serious games: an experience on emergency training
No full textEmergency preparedness is a promising application field for digital serious games enabling the simulation of real emergency scenarios and allowing a high learning transfer thanks to engagement and focus on specific tasks. Games can also play a role in the assessment that may happen without interrupting the learner, observing and evaluating what she is doing. Based on these premises we defined a serious game for evacuation training targeted to primary and secondary school students. The student is immersed in a virtual environment representing her school during an emergency with the aim of evacuating the building and adopting the correct behaviour. Any performed action is evaluated by the system, feedback is provided immediately and also when the game ends. Recovery micro-learning resources are then arranged and provided to the students to explain any errors they made and to help them reach better performances. The system is based on the application of a theoretical framework for evidence-based assessment where knowledge-based structures have been used to represent emergency skills and to relate them to possible actions within the game. An experiment with students coming from four Italian schools has been also performed to validate the models and the prototype

On periodicity of p-adic Browkin continued fractions
No full textThe classical theory of continued fractions has been widely studied for centuries for its important properties of good approximation, and more recently it has been generalized to p-adic numbers where it presents many differences with respect to the real case. In this paper we investigate periodicity for the p-adic continued fractions introduced by Browkin. We give some necessary and sufficient conditions for periodicity in general, although a full characterization of p-adic numbers having purely periodic Browkin continued fraction expansion is still missing. In the second part of the paper, we describe a general procedure to construct square roots of integers having periodic Browkin p-adic continued fraction expansion of prescribed even period length. As a consequence, we prove that, for every n = 1, there exist infinitely many vm ? Q(p) with periodic Browkin expansion of period 2(n), extending a previous result of Bedocchi obtained for n = 1
