Estudi realitzat a partir d’una estada a l’Institut Desenvolupat a School of Comparative American Studies adscrit a la University of Warwick, Regne Unit, entre 2011 i 2012. Aquest projecte analitza en primer lloc la mobilització popular del primer liberalisme i la formació de les primeres organitzacions polítiques liberals que es constituïren a partir de les societats secretes i es propagaren a través dels principals centres de sociabilitat liberal: les societats patriòtiques. En segon lloc mitjançant l’estudi de la mobilitat dels liberals entre l’Espanya metropolitana i el virregnat de Nueva Espanya demostra com es dibuixà un nou model polític basat en el federalisme. El tercer aspecte d’anàlisi és com els exiliats catalans a Anglaterra reberen el suport de la Foreign Bible Society perquè havia mantingut contactes des dels primers anys vint amb l’alt clergat espanyol. El darrer aspecte de la recerca abasta l’estudi de l’espai urbà en relació amb les pràctiques polítiques dels ciutadans a partir de l’anàlisi de la formació i ampliació de les places de la ciutat de Barcelona durant la primera meitat del segle XIX.

Aquest treball parteix de l’anàlisi de les dades sobre informes d’adequació de l’habitatge per a l’obtenció d’una autorització de reagrupament familiar realitzats per l’Ajuntament de Barcelona des de 2005 fins 2009, i del registre administratiu de les sol•licituds de reagrupament familiar presentades a les quatre subdelegacions del Govern a Catalunya des de 2004 fins 2010. Per a procedir a la seva anàlisi s’ha hagut de fer un important treball de depuració, harmonització i anonimització d’unes dades procedents de registres administratius no pensades per la seva explotació estadística. L’anàlisi demogràfica ha posat en relleu la importància dels rols de gènere en les estratègies familiars que acabaran conformant el perfil sociodemogràfic tant de les persones reagrupades com de les reagrupadores. També s’ha pogut veure com no hi ha una relació directa entre les persones estrangeres residents en cada municipi i les pautes de reagrupament familiar. La davallada del reagrupament familiar és deguda en bona part a la crisi econòmica, no obstant per a entendre la seva evolució en conjunt cal tenir en compte a més els factors legislatius (la Normalització del 2005 que explica el creixement de 2006 i 2007, però també l’entrada dels romanesos a la UE en 2007), així com la pròpia dinàmica familiar de la població immigrada, amb un esgotament del potencial reagrupadors per a les nacionalitats que precisament protagonitzaren el boom migratori (llatinoamericans). La legislació en matèria de reagrupament familiar s’ha basat en tres principis que han tingut un efecte indubtable i de vegades contrari a l’esperat: 1) la discriminació entre raons econòmiques i familiars en les migracions; 2) La restricció del dret de reagrupar a la definició nuclear de la família; i, 3) L’assumpció de la formació pre-migratòria de la família a reagrupar. Els resultats d’aquest informe aporten indicis que aquesta aproximació apriorística ha tingut efectes perversos, començant pel volum considerable de reagrupacions de facto.

El document que us presentem té com a base les consultes que ens han fet i ens fan els alumnes dels nostres tallers sobre com gestionar la seva obra artística personal tant dins com fora de la presó. La majoria de demandes, però, són sobre com poder entrar dins el món de l’art sense perdre-hi cap dret ni cap percepció econòmica per manca de coneixements. Sovint no els hem pogut oferir una resposta professional i real al món de l’art comercial o no. El document inclou un decàleg, basat en l’estatut de l’artista, que parla de la llibertat de creació i expressió, els drets morals, la confiança, lleialtat i transparència, la difusió de l’obra, el contracte per escrit, els drets econòmics per l’explotació, la relació artista-galerista, la remuneració econòmica, la producció artística i el suport a la recerca i l’arbitratge.

CSCL applications are complex distributed systems that posespecial requirements towards achieving success in educationalsettings. Flexible and efficient design of collaborative activitiesby educators is a key precondition in order to provide CSCL tailorable systems, capable of adapting to the needs of eachparticular learning environment. Furthermore, some parts ofthose CSCL systems should be reused as often as possible inorder to reduce development costs. In addition, it may be necessary to employ special hardware devices, computational resources that reside in other organizations, or even exceed thepossibilities of one specific organization. Therefore, theproposal of this paper is twofold: collecting collaborativelearning designs (scripting) provided by educators, based onwell-known best practices (collaborative learning flow patterns) in a standard way (IMS-LD) in order to guide the tailoring of CSCL systems by selecting and integrating reusable CSCL software units; and, implementing those units in the form of grid services offered by third party providers. More specifically, this paper outlines a grid-based CSCL system having these features and illustrates its potential scope and applicability by means of a sample collaborative learning scenario.

Collage is a pattern-based visual design authoring tool for the creation of collaborative learning scripts computationally modelled with IMS Learning Design (LD). The pattern-based visual approach aims to provide teachers with design ideas that are based on broadly accepted practices. Besides, it seeks hiding the LD notation so that teachers can easily create their own designs. The use of visual representations supports both the understanding of the design ideas and the usability of the authoring tool. This paper presents a multicase study comprising three different cases that evaluate the approach from different perspectives. The first case includes workshops where teachers use Collage. A second case implies the design of a scenario proposed by a third-party using related approaches. The third case analyzes a situation where students follow a design created with Collage. The cross-case analysis provides a global understanding of the possibilities and limitations of the pattern-based visual design approach.

This paper describes a Computer-Supported Collaborative Learning (CSCL) case study in engineering education carried out within the context of a network management course. The case study shows that the use of two computing tools developed by the authors and based on Free- and Open-Source Software (FOSS) provide significant educational benefits over traditional engineering pedagogical approaches in terms of both concepts and engineering competencies acquisition. First, the Collage authoring tool guides and supports the course teacher in the process of authoring computer-interpretable representations (using the IMS Learning Design standard notation) of effective collaborative pedagogical designs. Besides, the Gridcole system supports the enactment of that design by guiding the students throughout the prescribed sequence of learning activities. The paper introduces the goals and context of the case study, elaborates onhow Collage and Gridcole were employed, describes the applied evaluation methodology, anddiscusses the most significant findings derived from the case study.

Two important challenges that teachers are currently facing are the sharing and the collaborative authoring of their learning design solutions, such as didactical units and learning materials. On the one hand, there are tools that can be used for the creation of design solutions and only some of them facilitate the co-edition. However, they do not incorporate mechanisms that support the sharing of the designs between teachers. On the other hand, there are tools that serve as repositories of educational resources but they do not enable the authoring of the designs. In this paper we present LdShake, a web tool whose novelty is focused on the combined support for the social sharing and co-edition of learning design solutions within communities of teachers. Teachers can create and share learning designs with other teachers using different access rights so that they can read, comment or co-edit the designs. Therefore, each design solution is associated to a group of teachers able to work on its definition, and another group that can only see the design. The tool is generic in that it allows the creation of designs based on any pedagogical approach. However, it can be particularized in instances providing pre-formatted designs structured according to a specific didactic method (such as Problem-Based Learning, PBL). A particularized LdShake instance has been used in the context of Human Biology studies where teams of teachers are required to work together in the design of PBL solutions. A controlled user study, that compares the use of a generic LdShake and a Moodle system, configured to enable the creation and sharing of designs, has been also carried out. The combined results of the real and controlled studies show that the social structure, and the commenting, co-edition and publishing features of LdShake provide a useful, effective and usable approach for facilitating teachers' teamwork.

Designs of CSCL (Computer Supported Collaborative Learning)activities should be flexible, effective and customizable toparticular learning situations. On the other hand, structureddesigns aim to create favourable conditions for learning. Thus,this paper proposes the collection of representative and broadlyaccepted (best practices) structuring techniques in collaborative learning. With the aim of establishing a conceptual common ground among collaborative learning practitioners and softwaredevelopers, and reusing the expertise that best practicesrepresent, the paper also proposes the formulation of these techniques as patterns: the so-called CLFPs (CollaborativeLearning Flow Patterns). To formalize these patterns, we havechosen the educational modelling language IMS Learning Design (IMS-LD). IMS-LD has the capability to specify many of the collaborative characteristics of the CLFPs. Nevertheless, the language bears limited capability for describing the services that mediate interactions within a learning activity and the specification of temporal or rotated roles. This analysis isdiscussed in the paper, as well as our approaches towards thedevelopment of a system capable of integrating tools using IMSLDscripts and a CLFP-based Learning Design authoring tool.

When applying a Collaborative Learning Flow Pattern (CLFP) to structure sequences of activities in real contexts, one of the tasks is to organize groups of students according to the constraints imposed by the pattern. Sometimes,unexpected events occurring at runtime force this pre-defined distribution to be changed. In such situations, an adjustment of the group structures to be adapted to the new context is needed. If the collaborative pattern is complex, this group redefinitionmight be difficult and time consuming to be carried out in real time. In this context, technology can help on notifying the teacher which incompatibilitiesbetween the actual context and the constraints imposed by the pattern. This chapter presents a flexible solution for supporting teachers in the group organization profiting from the intrinsic constraints defined by a CLFPs codified in IMS Learning Design. A prototype of a web-based tool for the TAPPS and Jigsaw CLFPs and the preliminary results of a controlled user study are alsopresented as a first step towards flexible technological systems to support grouping tasks in this context.

Collaborative activities, in which students actively interact with each other, have proved to provide significant learning benefits. In Computer-Supported Collaborative Learning (CSCL), these collaborative activities are assisted by technologies. However, the use of computers does not guarantee collaboration, as free collaboration does not necessary lead to fruitful learning. Therefore, practitioners need to design CSCL scripts that structure the collaborative settings so that they promote learning. However, not all teachers have the technical and pedagogical background needed to design such scripts. With the aim of assisting teachers in designing effective CSCL scripts, we propose a model to support the selection of reusable good practices (formulated as patterns) so that they can be used as a starting point for their own designs. This model is based on a pattern ontology that computationally represents the knowledge captured on a pattern language for the design of CSCL scripts. A preliminary evaluation of the proposed approach is provided with two examples based on a set of meaningful interrelated patters computationally represented with the pattern ontology, and a paper prototyping experience carried out with two teaches. The results offer interesting insights towards the implementation of the pattern ontology in software tools.
