Artificial Pleasure and Pain Antagonism Mechanism in a Social Robot

2017

The goal of the work is to build some Python modules that allow the Nao robot to emulate a somatosensorial system similar to the human one. Assuming it can perceive some feelings similar to the ones recognized by the human system, it will be possible to make it react appropriately to the external stimuli. The idea is to have a group of software sensors working simultaneously, providing some feedback to show how the robot is feeling at a particular time. It will be able to feel articular pain and stress, to perceive people in his surroundings (and in a future work to react according to the knowledge of them with face recognition), feel pleasure by recognizing caresses on his head and respond…

Sensibilidad intercultural y satisfacción con la vida en alumnado autóctono e inmigrante

2019

El objetivo de esta investigación ha sido explorar la relación entre diversas variables personales y escolares (empatía, autoconcepto y percepción de ayuda del profesor), la sensibilidad intercultural y la satisfacción con la vida en alumnado de tercer ciclo de educación primaria. Además, se han analizado posibles diferencias en estas variables entre alumnado autóctono e inmigrante. En esta investigación participaron 473 alumnos (92,2% autóctonos; 7,8% inmigrantes), 52% chicos y 48% chicas, de entre 10 y 13 años (M = 10,79; DT = 0,74). Los resultados obtenidos indican mayor sensibilidad intercultural y autoconcepto emocional en alumnado inmigrante, y mayor satisfacción con la vida y autocon…

Social Animation in Complex Environments

2007

This work presents a market-based social model to produce good quality behavioral animations for groups of intelligent virtual agents. The social model coordinates the activities of groups of virtual characters and also includes social actions in the agent decision-making. We follow the Multi-Agent Resource Allocation approach presented in [2], where agents express their preferences using utility functions. The dynamics of social interactions is inspired by the theory of Piaget [3] over which we have implemented reciprocal task exchanges.

Secondary school students’ collaboration during dyadic debates face-to-face and through computer chat

2009

Communicative competence needed in today's constructive learning environments both in virtual and physical classrooms requires most of all critical and argumentative thinking skills as well as abilities to use reciprocal and collaborative language. This study clarifies the quality of secondary school students' collaboration in dyadic face-to-face and computer chat debates during argumentative discussions. The speech acts produced in 24 debates were first classified into either on-task or off-task categories. The on-task speech acts were then further classified into six collaborative and two non-collaborative categories. The students commonly presented questions and made requests for clarifi…

Community Resilience in Crises : Technology and Social Media Enablers

2014

Technology can contribute greatly to disaster resilience, especially by enhancing the interconnectedness between the authorities and the public and by facilitating the rapid exchange of information. This special issue of Human Technology: An Interdisciplinary Journal on Humans in ICT Environments is focused on technology and social media enablers of community resilience. Crises take on a variety of shapes and forms—natural or health disasters, terroristic and criminal acts, technology malfunctions, and large-scale accidents—at the local, regional, national, and global levels. Crisis management plans, created and implemented at the organizational level, typically involve public service and i…

Mobile social networking in theory and practice

2008

Mobile social networks have gained the attention of the media, academy and mobile market. Despite of the robust tradition of network and community studies, mobile social networks are often addressed improperly. This paper presents a theoretical framework to study mobile social networking and examines the design implications of results of an exploratory study conducted with a group of 18 young adults in Finland. The findings of this study indicate that the quality of mobile applications offering social networking could be greatly increased by integrating the knowledge of two traditions that so far developed in parallel, namely the mathematical as well as social approaches to social networks.

A model of internal and external competition in a High Speed Rail line

2015

This paper is a contribution to evaluate structural and behavioral changes in railway passenger markets. The novel elements of our analysis are the following: (i) the consideration of inter-modal and intra-modal competition, (ii) the presence of public and private operators, and (iii) endogenous service frequency. After calibrating the model using actual data from two Spanish High Speed Rail lines, simulation exercises allow us to conclude the following. Privatization, whether entry occurs or not, would prompt an increase in prices and a reduction in the number of train services, eventually leading to welfare decreases, as compared with a regime where the incumbent rail operator remained pu…

Conflict between parasites with different transmission strategies infecting an amphipod host

2005

Competition between parasites within a host can influence the evolution of parasite virulence and host resistance, but few studies examine the effects of unrelated parasites with conflicting transmission strategies infecting the same host. Vertically transmitted (VT) parasites, transmitted from mother to offspring, are in conflict with virulent, horizontally transmitted (HT) parasites, because healthy hosts are necessary to maximize VT parasite fitness. Resolution of the conflict between these parasites should lead to the evolution of one of two strategies: avoidance, or sabotage of HT parasite virulence by the VT parasite. We investigated two co-infecting parasites in the amphipod host, G…

A Reconfigurable Immersive Workbench and Wall-System for Designing and Training in 3D Environments

2007

Virtual and Augmented Reality have been widely used in many scientific fields for the last two decades in order to visualize complex data and information. Although both techniques are oriented to show users complex 3D environments by means of an intuitive and easy mechanism, they use to become useless to manipulate the information in an intuitive and realistic way. In this paper, we present SOROLLA, a new concept of workbench designed for virtual and augmented reality purposes and specially oriented to the fields of teleeducation and engineering. Unlike other proposals, SOROLLA not only allows an easy utilization and configuration, but also shows a cost-effective immersive visualization sys…
