Aquest projecte ha estat impulsat per l’Observatori de la Divulgació de la Ciència (ODC) de la UAB i dut a terme a l’Institut de Ciència i Tecnologia Ambientals (ICTA). Està emmarcat dins el marc del nou Programa Europeu Horizon 2020 i més específicament dels conceptes establerts per la RRI. L’objectiu d’aquest projecte és analitzar la comunicació científica que duu a terme l’ICTA cap a al societat i conèixer la filosofia, els incentius i la motivació de l’ICTA i els seus investigadors per donar a conèixer la seva recerca a la ciutadania. L’anàlisi de la comunicació de l’ICTA consta d’un anàlisi del contingut de la pàgina web del centre de recerca, una entrevista feta a la directora de l’institut i un qüestionari realitzat a 14 investigadors Les formes de comunicació que més utilitzen són els articles científics en revistes dirigides a públic acadèmic. Respecte la comunicació no acadèmica, s’ha pogut observar que la majoria dels investigadors, tot i la manca de facilitats realitzaven activitats per interès personal, molts cops però, no comuniquen la seva recerca, principalment perquè tenen altres tasques de docència, de recerca i gestió per atendre. Hi ha una minoria que es refereix a la comunicació científica com un “estil essencialment vocacional”. Per tal d’impulsar i promoure una estratègia contínua i efectiva de comunicació científica cal definir un pla de comunicació a nivell institucional que contribueixi a millorar les capacitats divulgatives, comunicatives i educatives de l’ICTA per tal d’ajudar a les persones que hi fan recerca a apropar la seva tasca a la societat a la que pertanyen.

The orchestration of collaborative learning processes in face-to-facephysical settings, such as classrooms, requires teachers to coordinate students indicating them who belong to each group, which collaboration areas areassigned to each group, and how they should distribute the resources or roles within the group. In this paper we present an Orchestration Signal system,composed of wearable Personal Signal devices and an Orchestration Signal manager. Teachers can configure color signals in the manager so that they are transmitted to the wearable devices to indicate different orchestration aspects.In particular, the paper describes how the system has been used to carry out a Jigsaw collaborative learning flow in a classroom where students received signals indicating which documents they should read, in which group they were and in which area of the classroom they were expected to collaborate. The evaluation results show that the proposed system facilitates a dynamic, visual and flexible orchestration.

Background:In January 2011 Spain modified clean air legislation in force since 2006, removing all existing exceptions applicable to hospitality venues. Although this legal reform was backed by all political parties with parliamentary representation, the government's initiative was contested by the tobacco industry and its allies in the hospitality industry. One of the most voiced arguments against the reform was its potentially disruptive effect on the revenue of hospitality venues. This paper evaluates the impact of this reform on household expenditure at restaurants and bars and cafeterias. Methods and empirical strategy:We use micro-data from the Encuesta de Presupuestos Familiares (EPF) for years 2006 to 2012 to estimate "two part" models where the probability of observing a positive expenditure and, for those who spend, the expected level of expenditure are functions of an array of explanatory variables. We apply a before-after analysis with a wide range of controls for confounding factors and a flexible modeling of time effects.Results:In line with the majority of studies that analyze the effects of smoking bans using objective data, our results suggest that the reform did not cause reductions in households' expenditures on restaurant services or on bars and cafeteria services.

In this paper, the sensor of an optical mouse is presented as a counterfeit coin detector applied to the two-Euro case. The detection process is based on the short distance image acquisition capabilities of the optical mouse sensor where partial images of the coin under analysis are compared with some partial reference coin images for matching. Results show that, using only the vision sense, the counterfeit acceptance and rejection rates are very similar to those of a trained user and better than those of an untrained user.

Una eficaz acción educativa obliga necesariamente a plantearse en profundidad la autoevaluación como modelo de cambio y la participación de todos los estamentos de la comunidad educativa. Un mayor o menor grado de participación viene a ser un indicador que nos permite valorar cualquier propuesta de «calidad», «reforma» o «innovación». El modelo B.A.D.I. yen especial su instrumento modular, responde a las exigencias particulares de reflexión, análisis y toma de decisiones que se realiza en cada centro para responder adecuadamente a cualquier planteamiento innovador. Los principios fundamentales de este modelo se resumen en: A. Es un modelo de concepción organicista, estamental, con definición ideológica. B. Responde a un enfoque fundamentalmente rogeriano. C. Participa de los enfoques social, abierto, dinámico, cultural y positivo. Comparte la teoría moderna de la organización y sus indicadores se agrupan en cuatro fases: Criterial, presupuestaria, metodológica e informativa. D. Se identifica con los modelos centrados en la evaluación de cambio, de forma especial con la autoevaluación. La flexibilidad que caracteriza al modelo viene dado por el instrumento modular de área o de criterio, como resultado de la participación y el consenso de todos los estamentos de la institución educativa.

Abstract Purpose: Several well-known managerial accounting performance measurement models rely on causal assumptions. Whilst users of the models express satisfaction and link them with improved organizational performance, academic research, of the realworld applications, shows few reliable statistical associations. This paper provides a discussion on the"problematic" of causality in a performance measurement setting. Design/methodology/approach: This is a conceptual study based on an analysis and synthesis of the literature from managerial accounting, organizational theory, strategic management and social scientific causal modelling. Findings: The analysis indicates that dynamic, complex and uncertain environments may challenge any reliance upon valid causal models. Due to cognitive limitations and judgmental biases, managers may fail to trace correct cause-and-effect understanding of the value creation in their organizations. However, even lacking this validity, causal models can support strategic learning and perform as organizational guides if they are able to mobilize managerial action. Research limitations/implications: Future research should highlight the characteristics necessary for elaboration of convincing and appealing causal models and the social process of their construction. Practical implications: Managers of organizations using causal models should be clear on the purposes of their particular models and their limitations. In particular, difficulties are observed in specifying detailed cause and effect relations and their potential for communicating and directing attention. They should therefore construct their models to suit the particular purpose envisaged. Originality/value: This paper provides an interdisciplinary and holistic view on the issue of causality in managerial accounting models.

Does realistic lighting in an immersive virtual reality application enhance presence, where participants feel that they are in the scene and behave correspondingly? Our previous study indicated that presence is more likely with real-time ray tracing compared with ray casting, but we could not separate the effects of overall quality of illumination from the dynamic effects of real-time shadows and reflections. Here we describe an experiment where 20 people experienced a scene rendered with global or local illumination. However, in both conditions there were dynamically changing shadows and reflections. We found that the quality of illumination did not impact presence, so that the earlier result must have been due to dynamic shadows and reflections. However, global illumination resulted in greater plausibility - participants were more likely to respond as if the virtual events were real. We conclude that global illumination does impact the responses of participants and is worth the effort.

Study techniques in out of school secondary education in the province of Girona. It is important to provide students with different ways to study so they can find the most appropriate method for them. Our research focuses on the study techniques used in secondary education by those students attending classes out of school time. In order to conduct this research, we have developed a general questionnaire after reviewing the existing literature on the topic. Some of the results obtained with this study are the following: adolescents attach great importance to learn study techniques, being summaries, diagrams and underlining the most well-known strategies for them, and mind maps and teamwork the least popular ones; they prefer dynamic teaching and learning methodologies, such as making interactive discussions; tutoring is the most valued element. Based on the results obtained with the study, we have developed some proposals to facilitate the work of the teacher when teaching study techniques and helping students to improve their academic performance

A key strategic issue for banks is the implementation of internet banking. The ‘click and mortar’ model that complements classical branch banking with online facilities is competing with pure internet banks. The objective of this paper is to compare the performance of these two models across countries, so as to examine the role of differences in the banking system and technological progress. A fuzzy cluster analysis on the performance of banks in Finland, Spain, Italy and the UK shows that internet banks are hard to distinguish from banks that follow a click and mortar strategy; country borders are more important. We therefore explain bank performance by a group of selected bank features, country-specific economic and IT indicators over the period 1995-2004. We find that the strategy of banking groups to incorporate internet banks reflects some competitive edge that these banks have in their business models. Extensive technological innovation boosts internet banking.

El reconeixement dels gestos de la mà (HGR, Hand Gesture Recognition) és actualment un camp important de recerca degut a la varietat de situacions en les quals és necessari comunicar-se mitjançant signes, com pot ser la comunicació entre persones que utilitzen la llengua de signes i les que no. En aquest projecte es presenta un mètode de reconeixement de gestos de la mà a temps real utilitzant el sensor Kinect per Microsoft Xbox, implementat en un entorn Linux (Ubuntu) amb llenguatge de programació Python i utilitzant la llibreria de visió artifical OpenCV per a processar les dades sobre un ordinador portàtil convencional. Gràcies a la capacitat del sensor Kinect de capturar dades de profunditat d’una escena es poden determinar les posicions i trajectòries dels objectes en 3 dimensions, el que implica poder realitzar una anàlisi complerta a temps real d’una imatge o d’una seqüencia d’imatges. El procediment de reconeixement que es planteja es basa en la segmentació de la imatge per poder treballar únicament amb la mà, en la detecció dels contorns, per després obtenir l’envolupant convexa i els defectes convexos, que finalment han de servir per determinar el nombre de dits i concloure en la interpretació del gest; el resultat final és la transcripció del seu significat en una finestra que serveix d’interfície amb l’interlocutor. L’aplicació permet reconèixer els números del 0 al 5, ja que s’analitza únicament una mà, alguns gestos populars i algunes de les lletres de l’alfabet dactilològic de la llengua de signes catalana. El projecte és doncs, la porta d’entrada al camp del reconeixement de gestos i la base d’un futur sistema de reconeixement de la llengua de signes capaç de transcriure tant els signes dinàmics com l’alfabet dactilològic.
