Del prestatge a la web: la transformació de la formació de les col·leccions a les biblioteques universitàries

L’existència d’una xarxa mundial de comunicacions ubiqua i barata que cada vegada més permet obtenir documents de manera fàcil i gratuïta requerirà una transformació de les pràctiques de la formació de col·leccions a les biblioteques universitàries. Això estarà impulsat per una sèrie d’avenços específics, que inclouen la digitalització de continguts; el desenvolupament de repositoris d’impresos; el desenvolupament de lectors de llibres electrònics i de l’edició mitjançant la impressió sota demanda; el creixement de l’accés obert; els reptes per establir estructures d’edició acadèmica; i el creixement de noves formes d’activitats acadèmiques basades en l’obertura i la productivitat social. Si les biblioteques universitàries volen tenir èxit, hauran de desmuntar les col·leccions impreses patrimonials; passar de la selecció de llibres ítem a ítem a la compra sota demanda i a les subscripcions; gestionar la transició cap a revistes d’accés obert; centrar-se en conservar ítems únics; i desenvolupar nous mecanismes per finançar una infraestructura nacional.

Web 2.0+ educación: colaboración y recursos abiertos

Con la llegada de la web 2.0, ha sido posible para todos los usuarios participar y colaborar en la construcción del conocimiento, además de servir al dominio público gracias al intercambio libre y legal de los contenidos y a su reutilización. Además los recursos educativos abiertos, son un concepto reciente en lo que respecta a la organización del mundo de intercambio de variedad de materiales y herramientas educacionales, e instituciones como la UNESCO están interesadas en el desarrollo de estos, para ser utilizados en una escala tan amplia y global como sea posible. Sin embargo los REA están teniendo algunas dificultades para alcanzar su eficacia, ya que hay algunas diferencias cruciales en la organización y en la interacción de estas redes abiertas. Este artículo intenta realizar un análisis del intercambio libre y legal de los contenidos y su reutilización utilizadas como apoyo para el aprendizaje en diferentes espacios en línea, aprovechando las posibilidades tecnológicas que permiten conformar nuevas estructuras de socialización-colaboración en línea.

Disseny i implementació d'una web administrable i d'una aplicació per dispositius mòbils

En la societat en què vivim cada vegada agafen més importància les pàgines web, ja que és una eina d’informació molt útil i ràpida de consultar. Per això, no s’entén que una activitat empresarial sigui del tipus que sigui, no tingui representació a la xarxa. No és necessari que l’activitat en qüestió hagi de vendre productes a través d’Internet, sinó que simplement aquesta representació pot ajudar a donar a conèixer l’empresa i a ampliar la cartera de clients. De la mateixa manera, els dispositius mòbils també s’estan convertint en una eina important en la societat d’avui en dia i una bona aplicació pot aportar-te un avantatge en moltes de les feines diàries de les persones. D’aquestes idees sorgeix el projecte de fer la web i l’aplicació pel centre de fisioteràpia Fisioripoll. La web serviria per tenir un lloc a la xarxa on donar-se a conèixer i poder captar nous clients, i l’aplicació funcionaria com a eina pel propi centre, seria una espècie d’agenda electrònica per saber les hores que tens reservades els pròxims dies. Per aconseguir un bon funcionament de la web, s’ha demanat que la pàgina sigui administrable en els seus continguts. És a dir, que els propis gestors del centre puguin canviar els texts, les imatges dels diferents apartats i gestionar les reserves dels clients. En canvi, l’aplicació serà només una eina de consulta i no s’hauria de gestionar res. Per tal de dur a terme aquesta web s’ha tingut en compte utilitzar eines de programació de distribució lliure com és el llenguatge PHP, la base de dades MySQL, jQuery, el framework Phonegap per tal de poder construir una web i una aplicació amb cost de programari nul.

PHP-Nuke: software de código abierto en la gestión de contenidos web

Ante el gran incremento de información en el web, cada vez son más las empresas o instituciones que optan por implementar un sistema de gestión de contenidos, tanto en sus intranets como en la información que presentan a sus clientes o usuarios.

Arquitectura de la Información en entornos web

La arquitectura de la información, partiendo de los sólidos principios clásicos dela ciencia de la información tradicional, nace hacia finales de los años 90. Es una disciplina encargada de estructurar, organizar y etiquetarlos elementos que conforman los entorno sin formacionales para facilitar la búsqueda yrecuperación de la información que contieneny mejorar, así, la utilidad y el aprovechamientode la misma por parte de sus usuarios. Entrelos principales sistemas o estructuras que conforman la anatomía arquitectónica de un sitio web destacan los sistemas de organización,de etiquetado, de navegación, de búsqueda y los vocabularios controlados. Respecto a su praxis, la elaboración de la anatomía arquitectónica de un sitio webse centra en los aspectos relacionados con las necesidades de sus usuarios tipo.

Brief DISCERN, six questions for the evaluation of evidence-based content of health-related websites.

OBJECTIVE: To extract and to validate a brief version of the DISCERN which could identify mental health-related websites with good content quality. METHOD: The present study is based on the analysis of data issued from six previous studies which used DISCERN and a standardized tool for the evaluation of content quality (evidence-based health information) of 388 mental health-related websites. After extracting the Brief DISCERN, several psychometric properties (content validity through a Factor analysis, internal consistency by the Cronbach's alpha index, predictive validity through the diagnostic tests, concurrent validity by the strength of association between the Brief DISCERN and the original DISCERN scores) were investigated to ascertain its general applicability. RESULTS: A Brief DISCERN composed of two factors and six items was extracted from the original 16 items version of the DISCERN. Cronbach's alpha coefficients were more than acceptable for the complete questionnaire (alpha=0.74) and for the two distinct domains: treatments information (alpha=0.87) and reliability (alpha=0.83). Sensibility and specificity of the Brief DISCERN cut-off score > or =16 in the detection of good content quality websites were 0.357 and 0.945, respectively. Its predictive positive and negative values were 0.98 and 0.83, respectively. A statistically significant linear correlation was found between the total scores of the Brief DISCERN and those of the original DISCERN (r=0.84 and p<0.0005). CONCLUSION: The Brief DISCERN seems to be a reliable and valid instrument able to discriminate between websites with good and poor content quality. PRACTICE IMPLICATIONS: The Brief DISCERN is a simple tool which could facilitate the identification of good information on the web by patients and general consumers.

Engaging students in an e-learning experience : how to manage information resources through wikis and web blogs

The purpose of this paper is to describe the collaboration between librarians and scholars, from a virtual university, in order to facilitate collaborative learning on how to manage information resources. The personal information behaviour of e-learning students when managing information resources for academic, professional and daily life purposes was studied from 24 semi-structured face-to-face interviews. The results of the content analysis of the interview' transcriptions, highlighted that in the workplace and daily life contexts, competent information behaviour is always linked to a proactive attitude, that is to say, that participants seek for information without some extrinsic reward or avoiding punishment. In the academic context, it was observed a low level of information literacy and it seems to be related with a prevalent uninvolved attitude.

Emotions in a Web-based Learning Environment

The aim of this thesis was to examine emotions in a web-based learning environment (WBLE). Theoretically, the thesis was grounded on the dimensional model of emotions. Four empirical studies were conducted. Study I focused on students’ anxiety and their self-efficacy in computer-using situations. Studies II and III examined the influence of experienced emotions on students’ collaborative visible and non-collaborative invisible activities and lurking in a WBLE. Study II also focused on the antecedents of the emotions students experience in a web-based learning environment. Study IV concentrated on clarifying the differences between emotions experienced in face-to-face and web-based collaborative learning. The results of these studies are reported in four original research articles published in scientific journals. The present studies demonstrate that emotions are important determinants of student behaviour in a web-based learning, and justify the conclusion that interactions on the web can and do have an emotional content. Based on the results of these empirical studies, it can be concluded that the emotions students experience during the web-based learning result mostly from the social interactions rather than from the technological context. The studies indicate that the technology itself is not the only antecedent of students’ emotional reactions in the collaborative web-based learning situations. However, the technology itself also exerted an influence on students’ behaviour. It was found that students’ computer anxiety was associated with their negative expectations of the consequences of using technology-based learning environments in their studies. Moreover, the results also indicated that student behaviours in a WBLE can be divided into three partially overlapping classes: i) collaborative visible ii) non-collaborative invisible activities, and iii) lurking. What is more, students’ emotions experienced during the web-based learning affected how actively they participated in such activities in the environment. Especially lurkers, i.e. students who seldom participated in discussions but frequently visited the online environment, experienced more negatively valenced emotions during the courses than did the other students. This result indicates that such negatively toned emotional experiences can make the lurking individuals less eager to participate in other WBLE courses in the future. Therefore, future research should also focus more precisely on the reasons that cause individuals to lurk in online learning groups, and the development of learning tasks that do not encourage or permit lurking or inactivity. Finally, the results from the study comparing emotional reactions in web-based and face-to-face collaborative learning indicated that the learning by means of web-based communication resulted in more affective reactivity when compared to learning in a face-to-face situation. The results imply that the students in the web-based learning group experienced more intense emotions than the students in the face-to-face learning group.The interpretations of this result are that the lack of means for expressing emotional reactions and perceiving others’ emotions increased the affectivity in the web-based learning groups. Such increased affective reactivity could, for example, debilitate individual’s learning performance, especially in complex learning tasks. Therefore, it is recommended that in the future more studies should be focused on the possibilities to express emotions in a text-based web environment to ensure better means for communicating emotions, and subsequently, possibly decrease the high level of affectivity. However, we do not yet know whether the use of means for communicating emotional expressions via the web (for example, “smileys” or “emoticons”) would be beneficial or disadvantageous in formal learning situations. Therefore, future studies should also focus on assessing how the use of such symbols as a means for expressing emotions in a text-based web environment would affect students’ and teachers’ behaviour and emotional state in web-based learning environments.

Quality of web-based information on bipolar disorder

OBJECTIVE: To evaluate web-based information on bipolar disorder and to assess particular content quality indicators. METHODS: Two keywords, "bipolar disorder" and "manic depressive illness" were entered into popular World Wide Web search engines. Websites were assessed with a standardized proforma designed to rate sites on the basis of accountability, presentation, interactivity, readability and content quality. "Health on the Net" (HON) quality label, and DISCERN scale scores were used to verify their efficiency as quality indicators. RESULTS: Of the 80 websites identified, 34 were included. Based on outcome measures, the content quality of the sites turned-out to be good. Content quality of web sites dealing with bipolar disorder is significantly explained by readability, accountability and interactivity as well as a global score. CONCLUSIONS: The overall content quality of the studied bipolar disorder websites is good.

Evaluation de la qualité des sites internet francophones traitant de la dépendance à l'alcool [Assessing the quality of French language web sites pertaining to alcohol dependency]

The objective of this article is to systematically assess the quality of web-based information in French language on the alcohol dependence. The authors analysed, using a standardised pro forma, the 20 most highly ranked pages identified by 3 common internet search engines using 2 keywords. Results show that a total of 45 sites were analysed. The authors conclude that the overall quality of the sites was relatively poor, especially for the description of possible treatments, however with a wide variability. Content quality was not correlated with other aspects of quality such as interactivity, aesthetic or accountability.

Developing a web portal for managing marketing campaign information

Diplomityö liittyy Accenturen projektiin, jossa kehitettiin asiakkaalle CMS Web-portaali, jonka tarkoitus on tarjota mekanismi tuote- ja kampanjainformaation luontiin ja hallintaan sekä hallita niihin liittyviä budjettiprosesseja yrityksen Intranetissä. Työn tavoitteena on kuvata CMS-portaalin kehitysprosessia ja koota projektin aikana saadut opit ja parannusehdotukset. Tavoitteena on myös esittää ideoita havaittujen ongelmien ehkäisemiseksi tulevissa projekteissa. Portaalin kehitysprojektinsuurimmat haasteet liittyivät tietojärjestelmien kehitysympäristöihin, portaali- ja sisällönhallintapuolen yhdistämiseen sekä tiimikehitykseen. Kun portaaliprojekti tehdään asiakkaan tiloissa, ei täyttä kontrollia kehitysympäristöistä voi saada. Jos kehitysympäristöjen kanssa on ongelmia, niistä on syytä kommunikoida selkeästi ja ammattimaisesti asiakkaan kehitysympäristöistä vastaavalle taholle. Yhteistyö ja hyvät henkilökohtaiset suhteet asiakkaan kanssaovat tärkeitä. Jos portaalin sisällönhallintatarpeet eivät ole erittäin rajoittuneet, on suositeltavaa käyttää erillistä sisällönhallintaohjelmistoa portaalin sisällön hallitsemiseksi. Pienemmillekin projekteille tämä mahdollistaa paremmat laajennusmahdollisuudet. Portaali- ja sisällönhallintapuolenyhdistäminen kannattaa tehdä ohjelmistojen tarjoajien ohjeiden mukaan ja yleisiä menettelytapoja noudattaen. Yleisillä menettelytavoilla tarkoitetaan portaalinja sisällönhallinnan yhdistämisessä sitä, että portaali vastaanottaa sisältöä sisällönhallintajärjestelmältä, mutta kaikki sisällön muokkaustoimenpiteet tehdään sisällönhallintajärjestelmän käyttöliittymän kautta. Jos mukautettuja menettelytapoja on käytettävä, näiden kehittämiselle on varattava niiden vaatima aika. Tällöin Web-palveluiden käyttöä kannattaa harkita, koska Web-palvelut auttavat ohjelmistojen yhdistämisessä etenkin, kun yhdistäminen tehdään mukautetusti. Kun portaali tehdään käyttäen tiimikehitystyötä, on käytettävä myös versionhallintajärjestelmää, jolla estetään päällekkäisten muutosten mahdollisuus. Kehitysprosessin yhdenmukaistamiseksi on erittäin suositeltavaa tehdä yleinen kehitysohjedokumentti. Lisäksi on huolehdittava siitä, että kaikki kehittäjät noudattavat yleisiä kehitysohjeita, jotta yhdenmukaisuuden mukanaan tuomat edut saavutetaan mahdollisimman hyvin.

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.
