Abstract
Recent research shows that our performance and satisfaction at work depends more on motivational factors than the number of hours or the intensity of the work. In this paper we propose a framework aimed at managing motivation to improve workplace indicators. The key idea is to allow team managers and workers to negotiate over the conditions of the tasks so as to find the best motivation for the worker within the constraints of what the organization may offer.

Abstract
Litigation in court is still the main dispute resolution mode. However, given the amount and characteristics of the new disputes, mostly arising out of electronic contracting, courts are becoming slower and outdated. Online Dispute Resolution (ODR) recently emerged as a set of tools and techniques, supported by technology, aimed at facilitating conflict resolution. In this paper we present a critical evaluation on the use of Artificial Intelligence (AI) based techniques in ODR. In order to fulfill this goal, we analyze a set of commercial providers (in this case twenty four) and some research projects (in this circumstance six). Supported by the results so far achieved, a new approach to deal with the problem of ODR is proposed, in which we take on some of the problems identified in the current state of the art in linking ODR and AI.

Abstract
Negotiation is a collaborative activity that requires the participation of different parties whose behaviors influence the outcome of the whole process. The work presented here focuses on the identification of such behaviors and their impact on the negotiation process. The premise for this study is that identifying and cataloging the behavior of parties during a negotiation may help to clarify the role that stress plays in the process. To do so, an experiment based on a negotiation game was implemented. During this experiment, behavioral and contextual information about participants was acquired. The data from this negotiation game were analyzed in order to identify the conflict styles used by each party and to extract behavioral patterns from the interactions, useful for the development of plans and suggestions for the associated participants. The work highlights the importance of the knowledge about social interactions as a basis for informed decision support in situations of conflict.

Abstract
From the point of view of the Citizen, Justice is not always readily accessible. Either because it is a lengthy process, potentially expensive, sometimes unclear or simply scary, people will often avoid or withdraw from a judicial process, especially in those cases that involve relatively small amounts. This results in the giving up of a basic right, with the potential loss of rightful benefits. In this paper we briefly analyze the main aspects that impair access to Justice nowadays. We then move on to look at recent technological developments in the field of Online Dispute Resolution to argue that these can, in the near future, have a significant role in improving access to Justice. Specifically, we analyze the UMCourt Conflict Resolution Framework, developed by our research team, and address the different dimensions in which such tools contribute to make Justice more accessible, namely through better access to useful information, support in decision-making or more cost-effective processes.

Abstract
Personality traits play a key role in the shaping of emotions, moods, cognitions, and behaviours of individuals interacting in a virtual environment. The personalities one exhibits reflect one's perception of the world and are demonstrated in the act of communication. Thus, the evaluation of a message can be changed due to stress and mood variations. Being able to identify the degree of relationship between one's personality characteristics and one's current stress state can thus facilitate the communication process. In particular, in this paper it is studied the correlation between some personality traits and the stress levels exhibited by users' interactions. To do so a novel approach was followed in which an intelligent environment is used to support the stress recognition process providing important personality related information. An experiment has been designed for the purpose of addressing the estimation of relevant aspects of interactions that occur in a rich sensory environment. Outputs from the experiment, such as the relation between personality characteristics and stress, can be used to maximize the benefits of virtual environments and its applications in fields such as learning, medicine or conflict resolution. © 2014 Springer International Publishing Switzerland.

Abstract
In our day to day, we often experience a sense of being tired due to mental or physical workload. Along with that, there is also a feeling of degrading performance, even after the completion of simple tasks. These mental states however, are often not felt consciously or are ignored. This is an attitude that may result in human error, failure, and may lead to potential health problems together with a decrease in quality of life. States of acute mental fatigue may be detected with the close monitoring of certain indicators, such as productivity, performance and health indicators. In this paper, a model and prototype are proposed to detect and monitor acute acute fatigue, based on non-invasive Human-computer Interaction (HCI). This approach will enable the development of better working environments, with an impact on the quality of life and the work produced. © 2014 Springer International Publishing Switzerland.
