Direct and indirect verbal and bodily insults, and other forms of aggressive communication.
No full textThe paper analyzes cases of aggressive communication, defining the notion of insult and distinguishing it from other cases of verbal aggression like bad words, curses and imprecations. Then it analyzes real cases of verbal and non-verbal, direct and indirect insults and other aggressive acts in Italian political talk shows and social medi
Conflict and multimodal communication. Social research and machine intelligence.
No full textThis book explores the use of technology to detect, predict and understand social cues, in order to analyze and prevent conflict. Traditional human sciences approaches are enriched with the latest developments in Social Signal Processing aimed at an automatic understanding of conflict and negotiation. Communication—both verbal and non-verbal, within the context of a conflict—is studied with the aim of promoting the use of intelligent machines that automatically measure and understand the escalation of conflict, and are able to manage it, in order to support the negotiation process. Particular attention is paid to the integration of human sciences findings with computational approaches, from the application of correct methodologies for the collection of valid data to the development of computational approaches inspired by research on verbal and multimodal communication.
In the words of the trade unionist Pierre Carniti, "We should reevaluate conflict, since without conflict there is no social justice."
With this in mind, this volume does not approach conflict simply as an obstacle to be overcome, but as a concept to be fully analyzed. The philosophical, linguistic and psychological aspects of conflict, once understood, can be used to promote conflict management as a means for change and social justice
Cold Sprayed Metallic Coatings on Fibre-Reinforced Composites: A Machine Learning Approach for the Optimization of the Process
No full textCold spray additive manufacturing (CSAM) is a promising process for producing metallic layers on different substrates, using powders as a feedstock material. The metallic powders are deposited through pressured gas that reaches supersonic velocities. Due to the low heat input required, as the powders remain in solid-state, this technology is particularly suitable to coat thermo-sensitive materials such as composites. In this scenario, machine learning techniques can be crucial to improve the quality and understanding of this manufacturing process. The aim of this work is to predict the deformation and penetration of a particle upon impact using machine learning techniques in order to assess the properties of the coating. A univariate linear regression method was chosen to verify the feasibility of Theory Guided Machine Learning (TGML) techniques to predict the characteristics of the coating. The training dataset was obtained from both experimental data and computational data. It was confirmed that TGML could be a good route to pursue in order to optimize this process

Discrediting body. A multimodal strategy to spoil the other’s image
No full textIn political persuasion the persuader, beside bearing logical arguments and triggering emotions, must present one’s own image (one’s ethos) of a credible and reliable person, by enhancing three dimensions of it: competence, benevolence and dominance. In a parallel way, s/he may cast discredit on the opponent by criticizing, accusing or insulting on the same three dimensions. The work provides a description and a typology of multimodal discrediting moves focusing on the discrediter’s multimodal behavior. Based on an Italian corpus of political debates the analysis points out which facial expressions, gaze behavior, gestures, postures and prosodic features are used to convey discredit concerning the three target features of competence, benevolence and domi-nance. The qualitative study of discredit signals highlights the close relation with emotions and in this sense particular attention is given to them as triggers of the Audience’s evaluatio
Study of Bonding Mechanisms in Cold Spray of Metal-to-Polymer through a Numerical Approach
No full textCold spray (CS) is a low-temperature process that can be used for the metallization of temperature-sensitive materials, such as polymers or polymer matrix composites, so coupling the lightweight of polymers with the wear resistance, physical properties and hardness of metals. The study of the cold spray of metal particles applied to polymers is still in its early stage and the deposition mechanisms underlying the process are not thoroughly understood yet. Moreover, numerical studies of cold spray of metal-to-polymer are almost completely absent in literature. Therefore, aiming to fulfill this gap of knowledge, the scope of this work is to develop a numerical FE model capable of predicting the impact and the adhesion of a micron size metallic particle onto a polymeric substrate. The results from the model were compared with the experimental outcomes found in literature to establish the effectiveness of the model that was used as a powerful tool to better understand the bonding mechanisms and all the related phenomena ruling the CS process of metal-to-polymer
I am really certain of this! Towards a multimodal repertoire of signals communicating a high degree of certainty
No full textCommunicating vagueness by hands and face
No full textThis paper investigates the bodily signals of vagueness. After
presenting the conceptual notion of vagueness by contrasting with
uncertainty, approximation, confusion and ambiguity, the notion
of “metadiscursive vagueness signal” is presented, a case of
metadiscursive signals that convey “I am being vague”. Then a
qualitative analysis of bodily signals of vagueness is presented,
while singling out their physical features and outlining a typology
of signals and a typology of reasons to be vague
