This study analyses students’ perceptions of how the collaborative construction of a project online facilitates the acquisition of digital competences. The authors (María Pérez-Mateo, Marc Romero and Teresa Romeu) examine the methodological approach, within the context of the Universitat Oberta de Catalunya (Open University of Catalonia, UOC), of the subject: ICT Competences. This subject is conducted fully online at the UOC, and learners are required to engage in a collaborative project organized in 4 phases: Starting, Structuring, Developing, Concluding. Based on an evaluation research approach, quantitative and qualitative data from a survey have been triangulated. The conclusions reinforce the importance of Computer Supported Collaborative Learning (CSCL) processes, the need to put forward pedagogical proposals for the acquisition of both digital and collaborative competences and the relevant role of the teacher in this process.

Anonymization of graph-based data is a problem which has been widely studied in recent years and several anonymization methods have been developed. In this presentation the authors (Jordi Casas-Roma, Jordi Herrera-Joancomartí, Vicenç Torra) study different generic information loss measures for graphs comparing such measures to the cluster-specific ones. They evaluate whether the generic information loss measures are indicative of the usefulness of the data for subsequent data mining processes.

This presentation explores the variety of socio-material arrangements that enable older people to continue living independently. Drawing on a collection of ethnographic observations and interviews with telecare users the author (Daniel López) conducted at their homes in 2004 and 2008, he analyses in detail how the process of adopting the service makes visible and puts to the test certain arrangements that already exist, providing room for their modification and the creation of new ones. Rather than replacing existing arrangements with new solutions, I suggest maintenance infrastructures be devised to support the bounded and inalienable undertaking of caring for these arrangements which configure our autonomous, yet ageing lives.

In this presentation the authors (Angel A. Juan, Jarrod Goentzel, Tolga Bektas) discuss the vehicle routing problem with multiple driving ranges. The presentation describes an integer programming formulation and a multi-round heuristic algorithm that iteratively constructs a solution to the problem. Using a set of benchmarks adapted from the literature, the algorithm is employed to analyse how distance-based costs are increased when considering ‘greener’ fleet configurations – ie, when using electric vehicles with different degrees of autonomy.

Location-based applications require knowing the user position constantly in order to find out and provide information about user’s context. There is a need for new methods that calculate the location of users in indoor environments using smartphone sensors. In this presentation the authors (Laia Descamps-Vila, Antoni Perez-Navarro, Jordi Conesa) address that problem by presenting two methods that estimate the user position through a smartphone.

The use of P2P networks for multimedia distribution has spread out globally in recent years. Therefore, there is a strong need for a content distribution mechanism over P2P networks that do not pose security and privacy threats to the copyright holders or to end users, respectively. The existent systems for copyright and privacy protection employ cryptographic mechanisms at a cost of high computational burden which makes these systems impractical for distributing large files. In this presentation, the authors (Amna Qureshi, David Megías, Helena Rifà-Pous) propose and analyse a P2P content distribution system which allows efficient distribution of large-sized content while preserving the security and privacy of merchants and buyers, respectively. The experimental results confirm that the framework provides an efficient solution to copyright infringement issues over P2P networks, while protecting the end users’ privacy.

This presentation endeavours to shed some light on the notion of co-creation in the global context of new media user participation and its relationship with innovation. A non-directed case study focused on digital photography is presented, enabling an analysis of co-creation through the lens of the theories of creativity. Consequently, through connecting creativity with this fieldwork, the authors (Gemma San Cornelio and Edgar Gómez Cruz) suggest that the transformation of a cultural field by means of co-creation can lead to innovations that affect the entire field.

During the 2011 wave of protests, millions of citizens around the globe employed a vast range of digital media to demand greater democratic freedoms and social justice. Although mobile phones were widely used in all these protests, their significance remains unclear. This presentation draws from both qualitative and quantitative research to shed light on the recent uses of mobile technologies for social protest, with Spain’s Indignados (or 15M) movement as the case study. The authors (Arnau Monterde and John Postill) argue for the importance of processual analyses of the new protests that situate the uniqueness of each mobile technology and “mobile ensemble” within a particular moment in the collective biography of a movement. This approach reveals the importance of smartphones as new articulators of online spaces and occupied physical spaces, especially via Twitter and live streaming.

Integrity aims to ensure that the actions of public officials and employees are consistent with the law in order to prevent conflicts of interest and corruption. Conflicts of interest can lead to favouritism, abuse of power, discrimination, a lack of impartiality and objectivity, and, ultimately, corruption. Integrity facilitates appropriate management of the various interests at stake and, thus, prevents conflicts of interest that could lead to corruption in public procurement. In this presentation Agustí Cerrillo examines the mechanisms that ensure integrity in public procurement through transparency, good management, prevention of conflicts of interest and control and accountability mechanisms. It also explores how these mechanisms are reflected in the Spanish legal framework. It also analyses different measures to guarantee integrity included in the several plans of democratic regeneration passed by Spanish public administration. It also studies the Act 19/2013, of 3 December, on transparency, access to public sector information and good governance and Directive 2014/24/EU of the European Parliament and of the Council of 26 February 2014 on public procurement.

In recent years, the Smart City has become a very popular concept amongst policymakers and urban planners. However, at the same time as new urban Smart interventions are being designed and applied, insufficient attention has been paid to how these strategies are inserted into the wider political economy and, in particular, the political ecology of urban transformation. Therefore, in this presentation the authors (Hug March and Ramon Ribera-Fumaz) critically explore the implementation of the Smart City, tracing how the “environment” and environmental concerns have become an organising principle in Barcelona’s Smart City strategy. Through an urban political ecology prism they aim to critically reflect upon the contradictions of the currently existing Smart City in Barcelona and how Smart discourses and practices might be intentionally or unintentionally mobilised in ways that serve to depoliticise urban redevelopment and environmental management. The presentation stresses the need to repoliticize the debates on the Smart City and put citizens back at the centre of the urban debate.

In this presentation the authors (Milagros Sáinz, Julio Meneses, Beatriz-Soledad López and Sergi Fàbregues) examine young people’s gender-stereotyped beliefs and attitudes about people working in ICT. Nine hundred students from Catalonia (51% girls) enrolled in the last course of junior secondary education (mean of age=15 years old; S.D.=1.73) participated. As expected, the boys and girls held several stereotypical beliefs about ICT professionals. , These stereotypical beliefs described a masculine portrayal of ICT workers. Contrary to expectations, most of the students’ portrayals of people working in ICT were either positive or neutral, not negative. Likewise, and contrary to predictions, young males did not show more positive attitudes towards ICT professionals than girls. No gender differences were observed in the type of characteristics associated with ICT professionals. However, young females were more likely to offer feminine references about professions where ICT is the tool rather than the object of their work.

In this presentation the authors (Hug March, David Suarí, David Suarí) explore the shift towards desalination as an alternative to other water supply options such as river regulation or inter-basin water transfers. Desalination has been seen as the cure for everything that dams and inter-basin water transfers were unable to solve, including droughts, scarcities, social conflicts, environmental impacts, and political rivalries among the different Spanish regions. Desalination also means a new and powerful element in water planning and management that could provide water for the continuous expansion of the urban and tourism growth machine in Mediterranean Spain and thus relax possible water constraints on this growth. However, by 2012 most new desalination plants along the Mediterranean coast remained almost idle. Focusing on the case of the Mancomunidad de los Canales del Taibillla in south-eastern Spain, the authors objective is to develop a critical, integrated and reflexive perspective on the use of desalination as a source of water for urban and regional growth.

In recent years, several studies have been carried out into the reasons why students drop out of online higher education. However, more effort has gone into analyzing the causes of this phenomenon than into trying to characterize students who drop out, that is defining what a dropout is. As one of the main findings of this article, the authors (Josep Grau-Valldosera and Julià Minguillón) reach a pure empirical definition, at a programme level, of students who drop out of an online higher education context with non-mandatory enrolment. This definition is based on the probability of students not continuing a specific academic programme following several consecutive semesters of “theoretical break”, and is highly adaptable to institutions offering distance education with no permanence requirements. Analyzing the reasons behind these facts should help higher education institutions to make more sound and efficient decisions.

In this presentation the authors (David Masip, Michael S. North, Alexander Todorov, Daniel N. Osherson) introduce a computer vision problem from social cognition, namely, the automated detection of attitudes from a person’s spontaneous facial expressions. To illustrate the challenges, they introduce two simple algorithms designed to predict observers’ preferences between images (eg, of celebrities) based on covert videos of the observers’ faces. The two algorithms are almost as accurate as human judges performing the same task but nonetheless far from perfect.

Substantial multidisciplinary research has established foundational support for the consumer behaviour phenomenon that underlies the experience of telepresence within online social networks and other digital media products that provide hedonistic value. In this presentation the authors (Inma Rodriguez-Ardura and Francisco J.

Assessment of the correctness of software models is a key issue to ensure the quality of the final application. In this presentation the authors (Jordi Cabot, Robert Clarisó, Daniel Riera) present an automatic method for the verification of UML class diagrams extended with OCL constraints. The method works by translating the UML/OCL model into a Constraint Satisfaction Problem (CSP) that is evaluated using state-of-the-art constraint solvers to determine the correctness of the initial model.
