Mining operations are risky and often dangerous, with a high potential for accidents. Many of these accidents can be prevented by implementing safety measures. It is essential that mining companies take these measures seriously to protect the safety and wellbeing of their workers and ensure the sustainability of the industry. Among these measures,...

This paper aims to illustrate an automated system developed to give formative and personalized feedback to teachers in training. It is an expert system (Paviotti, Rossi & Zarka, 2012) that uses concrete examples, cases and scenarios to guide the engaged learners (Leake, 1996). In this regard, this system is able to create questionnaires, deliver th...

The numerous socio-economic and cultural transformations affect the various educational institutions bringing about significant changes. A central role is assumed by the teacher, considered one of the determining factors for students’ academic success. This work aims, on the one hand, to reconstruct a summary framework relating to the features char...

Orienting the attitudes of future teachers towards effective interventions: Restructuring misconceptions and naïve didactic points of view. The research on the teaching effectiveness and on the behaviour of expert teachers from an evidence based perspective allows today to envisage articulated training models that can accompany students-aspirants o...

The health emergency of 2020 has led many university professors to wonder about how to check that the information presented in their lessons generates a correct conceptual representation in their students and, above all, to ask themselves if they have carried out the right training actions capable of triggering what is called deep understanding, th...

In the recent years, numerous papers have discussed the use of concept maps in education. In this paper, we use the Dynamic Concept Maps (DCMs) in online learning environments as tools able to stimulate in students the processes of mutual interaction and hybridization between digital artefacts (DCMs) and analog artefacts (books) so as to encourage...

The aim of this paper is to present an empirical study with the intention of answering the question: can an intentionally structured online environment stimulate and enhance the processes of mutual interaction and hybridization between digital artefacts and analogic artefacts (books) so as to encourage the development of significant learning in stu...

The health emergency caused by Covid-19 and the suspension of teaching activities in presence have required a total rethinking of the school system. Kindergarten has been most affected by the consequences of an exclusively remote system. The purpose of this paper is to present the theoretical-empirical premises of a playful-educational software mod...

The organizational structures of public and local administration depend on many bureaucratic aspects. Emergencies and political factors instead of rational motivations related to knowledge, competences and profiles often influence the allocation of people in offices. In most cases, such situations generate dissatisfactions, low productivity and bec...

Italians children-students live a strong technological gap among different education instances: on the one hand, they are attending schools technologically still to the '80 years, on the other hand, they can rely on hyper-technological domestic-family environments where videogames, smartphones, internet are always available. In the school, all lear...

In the last years, the need for developing strategies, models and tools to manage competences clearly emerges in numerous scenarios. For instance, this emergence especially raises when it is required to realize effective recruiting platforms, decision support systems for human resource management, learning management systems and so on. This work pr...

Subject Ontologies represent conceptualizations of disciplinary domains in which concepts symbolize topics that are relevant for the considered domain and are associated each other by means of specific relations. Usually, these kind of lightweight ontologies are adopted in knowledge-based educational environments to enable semantic organization and...

In this paper, we present our results related to the definition of a methodology that combines augmented reality (AR) with semantic techniques for the creation of digital stories associated with museum exhibitions. In contrast to traditional AR approaches, we augment real-world elements by supplementing contents of a museum exhibition with addition...

In this paper a new offline model-free approximate Q-iteration is proposed. Following the idea of Fitted Q-iteration, we use a computational scheme based on Functional Networks, which have been proved to be a powerful alternative to Neural Networks, because they do not require a large number of training samples. We state a condition for the converg...

Open Innovation and Services Science are two distinct paradigms that share some principles 0. While some attempts to investigate open innovation according to a service science perspective exist, there is currently a gap with regards to the analysis of intermediaries of open innovation according to a service science perspective and even more regardi...

Governance can be considered as the way in which companies are directed and controlled. In any governance process, effective experience reuse is an increasingly important asset, representing source of competitive advantage in making decisions. As an example, an adequate level of experience is needed for taking decisions related to resource allocati...

In public and local administration contexts, the organizational structures depend on bureaucratic aspects. This often implies that people are engaged in offices and their allocation come from emergencies and political factors instead of rational motivations related to knowledge, competences and profiles. In most cases, such situations become gangre...

A good indexing of the learning objects is the better way to guarantee their reuse in the distance-learning context. We need to supply each content of a machine-understandable description including both technological and pedagogical information able to declare requirements and limits for its right use and to improve any research and delivery action...

Abstract In every context where the objective is matching needs of the users with fitting answers, the high-level performance becomes a requirement able to allow systems being useful and effective. The personalization may affect different moments of computer–humans interaction routing the users to the best answers to their needs. The most part of t...

The best way to guarantee these interactions is a good indexing. Each content needs a machine-understandable description able to declare requirements and...

Museum narratives are created from a conceptualization of events that can be structurally organized and referred to as the story. Therefore, the main process of developing a museum narrative is one of story-building. This paper presents a methodology to enrich the creation of stories for digital storytelling. The methodology is at the basis of a sm...

Object-relational data models (OR-data models) represent an emerging industry consensus on how objects should be integrated into the database world. Although these models have been studied in some derived syntactic forms (like NF2), their semantics aspects have not received much attention from the research community. The objective of this article i...
