This paper proposes modifications to the decision criteria that are now technically focused onto value creation and services delivery. It argues that the current emphasis on how, why, when and for whom systems are developed and the Agile Manifesto guidance for improving the human side of IT development using a bottom-up philosophy should be modified to address a wider set of benefits and risks while...
Compared to traditional channels, Internet transactions are intrinsically untrustworthy in nature. We investigate the impact of social identity and reciprocity on trusting and cooperative behavior in dynamic gift giving networks by means of an online laboratory experiment, with a main focus on value transfers among the users individually and directed towards the group. In this study, we display profile...
Improving the quality of care for fragile persons at home is necessary to ensure that the person can confront the tasks of everyday's life. The purpose of this article is to present a literature review and analysis about the quality of care for fragile persons at home, in order to analyze the quality of services received, the organizational development and the actor's participation. Our study was...
Utility-based learning is a key technique for addressing many real world data mining applications, where the costs/benefits are not uniform across the domain of the target variable. Still, most of the existing research has been focused on classification problems. In this paper we address a related problem. There are many relevant domains (e.g. ecological, meteorological, finance) where decisions are...
This paper introduces an unsupervised model for melodic segmentation that extends a method initially proposed in computational biology. In the model segments are identified as sections of maximal contrast within a musical piece, using for this the Jensen-Shannon divergence. The model is extended upon its original formulation, and experiments to test its performance are carried out for a small set...
Management of the renewable natural resources in Madagascar is gradually being transferred to the local communities. However, these local communities are struggling to assess the consequences of the management plans they must develop and implement on sustainability, within concurrent regulatory contexts. From this Malagasy case, we derived, from a law anthropology perspective, a generic model called...
Gibbs random fields play an important role in statistics, for example the autologistic model is commonly used to model the spatial distribution of binary variables defined on a lattice. However they are complicated to work with due to an intractability of the likelihood function. It is therefore natural to consider tractable approximations to the likelihood function. Composite likelihoods offer a...
Developing models for large systems is not a trivial task. Using only Discrete Event Simulation (DES) as a modelling technique may mean that the complexity of the underlying model will increase exponentially with the size of the model. An alternative to this is the use of System Dynamics (SD) for modeling large systems using the positive and negative feedback loops. However, for modelling a human-centric...
The Internet of Things (IoT) paradigm focuses on a network of objects, where devices communicate with human beings as well as other devices. This paper focuses on the identification of suitable metaphors and concepts for building IoT applications. It proposes an approach grounded on the contextualization of objects and their information in one or more spaces of things, defined according to different...
In this paper, we lay the foundations for a contextualisation of trust, the role it plays, and its different layers within the context of a novel paradigm: Social Cloud Computing. In a Social Cloud, trust plays a vital role as a collaboration enabler. However, trust is not trivial to define, observe, represent and analyse as precursors to understand exactly what role it plays in the enablement of...
Motion capture might become one key feature of future Wireless Body Sensor Networks (WBSN), allowing new applications such as home activity monitoring, nomadic postural rehabilitation or sportive gesture recording through standard on-body communications. In this context we present herein a stand-alone solution that enables the localization of wearable wireless nodes relatively to a body-strapped Local...
Decades of research have been committed to developing effective business logistics systems. In contrast, the important design principles for effective humanitarian logistics systems remains poorly understood. Current research focuses largely on applying business models to humanitarian logistics, However, there remains a fundamental mismatch between business logistics models, and humanitarian logistics...
While internationally there is an awareness that we need new, innovative approaches to engineering education, it is unclear whether a pioneering pedagogy within one cultural context will readily transfer and find acceptance in a very different cultural context. In this paper, we report on a three-site, collaborative experiment in using problem-driven learning in an introductory engineering class....
Developing and using models is an important skill employed by practicing engineers that is difficult to cultivate in students. One way to help students develop modeling capability is through feedback. Feedback has been shown to be effective in helping students close the gap between actual and desired performance. This case study investigates the effect of feedback on student teams' use of models in...
This paper presents initial results of a three-year research project entitled ATLANTIDE, which is aimed at developing a comprehensive digital archive of reference models of Italian distribution networks, including forecasted load and generation development evolving towards future smart grid scenarios. Such reference network models and evolutionary scenarios should provide a useful benchmark for testing...
In the recent years the following two trends have been accelerated: on the one hand, as Content Services became at the center of Internet usages, OTTs strengthen their position. On the other hand, in several cases, Telcos are seeing their role shrinking to “dumb pipes” providers. This paper introduces advanced Telcos' positioning in future content distribution services. In particular, it focuses on...
This paper presents Halos Networks as an architectural paradigm for developing ubiquitous networking and computing services at the edge of the networks A Halos Network is like a wireless network spontaneously emerging through the interactions of distributed resources embedding wireless communication capabilities. Halos Networks are capable of delivering services and data virally through multiple devices,...
This paper introduces a computational model for contagion and change of habitual behaviour in a social network. It considers both the level of individual mechanisms of habit formation, involving a person's attitudes, goals, intentions and relevant environmental cues, and the level of social mechanisms for the impact of others in a social network. Simulation experiments with the model for small-world...
This paper presents two bio-inspired methods addressing the problem of business process optimization. We provide a comparative approach for optimal business process flow selection and resource allocation using two of the most important bio-inspired meta-heuristics: Ant Colony Optimization and Bee Colony Optimization. Our approach does not use predefined rules for making the decisions when selecting...
Indigenous knowledge is the basis for many remote, rural, and marginalized communities in society and as such, is an important component in the educational development of members within these communities. Due to many reasons, including colonization, a lack of understanding by hegemonic societies, and disparate knowledge systems (for example, orally based), there is a risk of this knowledge disappearing...
