En una economia basada en el coneixement, la innovació del producte es considera un factor clau a l'hora de determinar la competitivitat, la productivitat i el creixement d'una companyia. No obstant això, l'experiència de les companyies demostra la necessitat d'un nou model de gestió de la innovació del producte: una gestió basada en el màrqueting, en què la cooperació i l'ús intensiu de les tecnologies de la informació i de la comunicació (TIC) són especialment importants. En els darrers anys, la bibliografia sobre màrqueting ha analitzat el paper de la cooperació en l'èxit del procés d'innovació. No obstant això, fins ara pocs treballs han estudiat el paper que té l'ús de les TIC en el màrqueting en l'èxit del desenvolupament de nous productes (NPD, New Product Development en anglès). És una omissió curiosa, tenint en compte que el nou entorn competitiu és definit per una economia i una societat basades principalment en l'ús intensiu de les TIC i del coneixement. L'objectiu d'aquest treball és investigar el paper que l'ús de les TIC en el màrqueting té en el procés de desenvolupament de nous productes, com a element que reforça la integració d'agents al projecte, afavorint l'establiment de relacions dirigides a la cooperació i l'adquisició d'intel·ligència de mercat útil en el procés de desenvolupament de nous productes. L'estudi d'una mostra de 2.038 companyies de tots els sectors de l'activitat econòmica a Catalunya ens permet contrastar hipòtesis inicials i establir un perfil de companyia innovadora basat en les importants relacions que hi ha entre la innovació, l'ús de TIC en el màrqueting i la integració. Sobresurten dues idees en la nostra anàlisi. En primer lloc, l'ús intensiu de les TIC en el màrqueting fa que la companyia sigui més innovadora, ja que percep que el seu ús ajuda a superar barreres a la innovació i accelera els processos, que es tornen més eficients. En segon lloc, incrementant l'ús de les TIC en el màrqueting es fa augmentar la predisposició de la companyia a integrar agents particulars en l'entorn de negoci en el desenvolupament del procés d'innovació i a col·laborar-hi, de manera que es millora el grau d'adaptació del nou producte a les demandes del mercat.

This article focuses on Barcelona"s art market to explore the underlying factors behind the clustering of art dealers in several of the city"s districts. Drawing upon quantitative and qualitative data, the article analyses how such clustering reveals a strategic action in the sense attributed to it by Crozier and Friedberg (1981). Gallery districts are not a reflection of structural factors (economic, urban development-related or social) but the result of a combination of strategic choices either individual or collective which explain the permanence of leading gallery districts or the emergence of new ones.

Thermal energy storage (TES) can increase the thermal energy effieresa, of a process by reusing the waste heat from industrial process, solar energy or other sources. There are different ways to store thermal energy: by sensible heat, by latest heat, by sorption process or by chemical reaction. This thesrs provides a-state-of-the-art review of the experimental performance of TES systems based on solid gas sorption process and chemical reactions. The importance of theses processes is that provides a heat loss free storage system with a high energy density.

Life cycle analysis (LCA) is a comprehensive method for assessing the environmental impact of a product or an activity over its entire life cycle. The purpose of conducting LCA studies varies from one application to another. Different applications use LCA for different purposes. In general, the main aim of using LCA is to reduce the environmental impact of products through guiding the decision making process towards more sustainable solutions. The most critical phase in an LCA study is the Life Cycle Impact Assessment (LCIA) where the life cycle inventory (LCI) results of the considered substances related to the study of a certain system are transformed into understandable impact categories that represent the impact on the environment. In this research work, a general structure clarifying the steps that shall be followed ir order to conduct an LCA study effectively is presented. These steps are based on the ISO 14040 standard framework. In addition, a survey is done on the most widely used LCIA methodologies. Recommendations about possible developments and suggetions for further research work regarding the use of LCA and LCIA methodologies are discussed as well.

The advent of new advances in mobile computing has changed the manner we do our daily work, even enabling us to perform collaborative activities. However, current groupware approaches do not offer an integrating and efficient solution that jointly tackles the flexibility and heterogeneity inherent to mobility as well as the awareness aspects intrinsic to collaborative environments. Issues related to the diversity of contexts of use are collected under the term plasticity. A great amount of tools have emerged offering a solution to some of these issues, although always focused on individual scenarios. We are working on reusing and specializing some already existing plasticity tools to the groupware design. The aim is to offer the benefits from plasticity and awareness jointly, trying to reach a real collaboration and a deeper understanding of multi-environment groupware scenarios. In particular, this paper presents a conceptual framework aimed at being a reference for the generation of plastic User Interfaces for collaborative environments in a systematic and comprehensive way. Starting from a previous conceptual framework for individual environments, inspired on the model-based approach, we introduce specific components and considerations related to groupware.

Many classification systems rely on clustering techniques in which a collection of training examples is provided as an input, and a number of clusters c1,...cm modelling some concept C results as an output, such that every cluster ci is labelled as positive or negative. Given a new, unlabelled instance enew, the above classification is used to determine to which particular cluster ci this new instance belongs. In such a setting clusters can overlap, and a new unlabelled instance can be assigned to more than one cluster with conflicting labels. In the literature, such a case is usually solved non-deterministically by making a random choice. This paper presents a novel, hybrid approach to solve this situation by combining a neural network for classification along with a defeasible argumentation framework which models preference criteria for performing clustering.

L’objectiu principal d’aquesta investigació és analitzar per què les arts de cos estan tan presents en els museus del segle XXI. Per fer-ho, ens centrarem primer en conèixer la història de les arts del cos des dels seus inicis al carrer o galeries alternatives fins a l’entrada al museu. En segon lloc, farem una aproximació a l’evolució dels museus centrant-nos en els segles XX i XXI. En tercer lloc, investigarem com les arts del cos entren als museus i farem una recerca d’aquestes arts en el museu del segle XXI

[cat] La carpeta d'aprenentatge representa un punt de trobada dels grans temes que han ocupat la Didàctica d'ençà dels anys 90 del segle passat: el caràcter formatiu de l'avaluació, l'assumpte de les competències, la metacognició i el pensament crític de l'estudiant, el paper desenvolupat per les TIC, i la concepció d'un aprenentatge col·laboratiu i plantejat a llarg termini. En aquest article de revisió, hom estudia com aquests temes s'han concretat en la carpeta d'aprenentatge i n'han determinat la seva evolució. [eng] The learning portofolio represents a meeting point for the big questions than have concernend teaching since the 1990s: the formative character of the assessment, the issue of competencies, metacognition and the students's critical thinking, the role played by ICTs, and the idea of collaborative learning considered in the long term. The article looks at how these subjects have taken shape in the learning portofolio and how they have determinded its evolutin.

To involve citizens in developing the processes of city making is an objective that occupies part of the agenda of political parties in the context of the necessary renewal in representative democracy. This paper aims to provide some answers to the following questions: Is it possible to overcome the participatory processes based exclusively on the consultation? Is it possible to"train" residents to take an active role in decision-making? How can we manage, proactively, the relationship between public actors, technicians and politicians, in a participatory process? We analyse the process development for creating the Wall of Remembrance in the Barcelona neighbourhood of Baró de Viver, a work of public art, created and produced by its neighbours, in the context of a long participatory process focused on changing the image of the neighbourhood and the improvement of public space. This result and this process have been possible in a given context of cooperation among neighbours, local government and the research team (CR-Polis, Art, City, Society at the University of Barcelona). The development of a creative process of citizen participation between 2004 and 2011 made possible the direct management of decision making by the residents on the field of the design of public space in the neighbourhood. However, the material results of the process does not overshadow the great achievement of the project: the inclusion of a neighbourhood in taking informed decisions because of their empowerment in public space design and management of their remembrances.
