Customization, transparency and proximity: a user- centered content strategy applied to the design of a virtual library website

We present a case study of the redesign of the organizational presentation and content of the Virtual Library website at the Universitat Oberta de Catalunya (Open University of Catalonia, UOC), based on a user-centered design strategy. The aim of the redesign was to provide users with more intuitive, usable and understandable content (textual content, resources and services) by implementing criteria of customization, transparency and proximity. The study also presents a selection of best practices for applying these criteria to the design of other library websites.

Use of physiological constraints to identify quantitative design principles for gene expression in yeast adaptation to heat shock

Background: Understanding the relationship between gene expression changes, enzyme activity shifts, and the corresponding physiological adaptive response of organisms to environmental cues is crucial in explaining how cells cope with stress. For example, adaptation of yeast to heat shock involves a characteristic profile of changes to the expression levels of genes coding for enzymes of the glycolytic pathway and some of its branches. The experimental determination of changes in gene expression profiles provides a descriptive picture of the adaptive response to stress. However, it does not explain why a particular profile is selected for any given response. Results: We used mathematical models and analysis of in silico gene expression profiles (GEPs) to understand how changes in gene expression correlate to an efficient response of yeast cells to heat shock. An exhaustive set of GEPs, matched with the corresponding set of enzyme activities, was simulated and analyzed. The effectiveness of each profile in the response to heat shock was evaluated according to relevant physiological and functional criteria. The small subset of GEPs that lead to effective physiological responses after heat shock was identified as the result of the tuning of several evolutionary criteria. The experimentally observed transcriptional changes in response to heat shock belong to this set and can be explained by quantitative design principles at the physiological level that ultimately constrain changes in gene expression. Conclusion: Our theoretical approach suggests a method for understanding the combined effect of changes in the expression of multiple genes on the activity of metabolic pathways, and consequently on the adaptation of cellular metabolism to heat shock. This method identifies quantitative design principles that facilitate understating the response of the cell to stress.

Entre la beneficencia y la «familiaritas»: la contratación del «victum et vestitum» en los monasterios catalanes durante los siglos XI-XII. Una respuesta institucional alternativa ante el hambre como problema social

Desde finales del siglo XI, en Cataluña, los principales monasterios y cabildos de canónigos regulares disponen de limosnas que ofrecen la ratio alimenticia diaria a pequeños grupos de laicos, diferenciados de los pobres, vinculados a ellas a través de actos de donación de alodios o de autodonación personal. En este artículo se aborda la relación entre el auge de este nuevo tipo de caridad contractual y de alguna de las formas de la familiaritas en las que derivó, y las dificultades de una parte de la sociedad durante las carestías, así como el papel que jugaron las principales instituciones monásticas, situadas al frente de importantes señoríos, a la hora de mitigar los efectos de éstas sobre la población dependiente.

Promoting Metacognitive Skills in a CSCL environment: implications for instructional and technology design

This paper aims to better understand the development of students’ learning processes when participating actively in a specific Computer Supported Collaborative Learning system called KnowCat. To this end, a longitudinal case study was designed, in which eighteen university students took part in a 12-month (two semesters) learning project. During this time period, the students followed an instructional process, using some elements of KnowCat (KnowCat key features) design to support and improve their interaction processes, especially peer learning processes. Our research involved both supervising the students’ collaborative learning processes throughout the learning project and focusing our analysis on the qualitative evolution of the students’ interaction processes and on the development of metacognitive learning processes. The results of the current research reveal that the instructional application of the CSCL-KnowCat system may favour and improve the development of the students’ metacognitive learning processes. Additionally, the implications of the design of computer supported collaborative learning networks and pedagogical issues are discussed in this paper.

Els serveis socials en l'administració comarcal : marc legal i institucional

El govern de la Comuniata Autònoma de Catalunya ha reinstituït l'organització comarcal que ja havia implantat la Generalitat durant la II República, Ara però, s'ha otorgat als Consells Comarcals, com a òrgan de govern de les comarques, un marcat caràcter institucional i administratiu. Per tant, l'administració comarcal a Catalunya s'adscriu entre les administracions locals, i com un nou nivell intermedi entre el municipi i la província (mentre aquesta subsisteix) o bé la Comunitat Autònoma. Aquesta modificació del model estatal d'Administracions Públiques, evidentment, condiciona l'organització del sistema de serveis socials.El present treball pretén estudiar, a través del repositoir legislatiu, el marc institucional en el qual s'organitzen els serveis social d'àmbit comarcal. Això ens ha de permetre conèixer més el context pròxim en el què actuen els equips i professionals del medi comarcal. Ells són els principals destinataris d¡aquesta proposta d'anàlisis: però igualment pot ajudar als altres professionals a reflexionar sobre el procés d'estructuració dels serveis de benestar social que s'està desenvolupant a Catalunya

Design and optimization of selfnanoemulsifying drug delivery systems for enhanced dissolution of gemfibrozil

Self-nanoemulsifying drug delivery systems of gemfibrozil were developed under Quality by Design approach for improvement of dissolution and oral absorption. Preliminary screening was performed to select proper components combination. BoxBehnken experimental design was employed as statistical tool to optimize the formulation variables, X1 (Cremophor® EL), X2 (Capmul® MCM-C8), and X3 (lemon essential oil). Systems were assessed for visual characteristics (emulsification efficacy), turbidity, droplet size, polydispersity index and drug release. Different pH media were also assayed for optimization. Following optimization, the values of formulation components (X1, X2, and X3) were 32.43%, 29.73% and 21.62%, respectively (16.22% of gemfibrozil). Transmission electron microscopy demonstrated spherical droplet morphology. SNEEDS release study was compared to commercial tablets. Optimized SNEDDS formulation of gemfibrozil showed a significant increase in dissolution rate compared to conventional tablets. Both formulations followed Weibull mathematical model release with a significant difference in td parameter in favor of the SNEDDS. Equally amodelistic parameters were calculated being the dissolution efficiency significantly higher for SNEDDS, confirming that the developed SNEDDS formulation was superior to commercial formulation with respect to in vitro dissolution profile. This paper provides an overview of the SNEDDS of the gemfibrozil as a promising alternative to improve oral absorption.

Políticas universitarias de difusión de la información a través de la propia web institucional

La difusión de la información se ha convertido en uno de los elementos críticos en los planes estratégicos de las instituciones universitarias. Inquietadas por su posición en los rankings internacionales que evalúan este tipo de instituciones, las universidades comienzan a preocuparse también por sus estrategias de difusión de información y sus webs institucionales. En este trabajo se abordan las funciones principales de las webs universitarias; el proceso de análisis, diseño e implementación en la creación de este tipo de sitios webs; los elementos mínimos que deben incluirse en una guía de estilo de web universitaria; y algunos de los principales estándares y referencias nacionales e internacionales de ese tipo de guías.

A Learner-Centred Game-Design Approach: Impacts on teachers" creativity

This study presents an innovative pedagogical approach where teachers become game designers and engage in creative teaching practices. Within co-design training workshops, 21 Spanish primary and secondary school teachers have developed their own Game-Based Learning (GBL) scenarios, especially tailored to their teaching contexts and students profiles. In total, teachers developed 13 GBL scenarios and put them into practice in real teaching contexts. The present paper analyses the impacts of this learner-centred game design approach on teachers" creativity from three different points of view: the GBL design process, the GBL scenario, and the teaching processes at stake.

Inclusion and empowerment in public art and urban design

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.
