Structured abstract: Purpose: LibraryThing is a Web 2.0 tool allowing users to catalogue books using data drawn from sources such as Amazon and the Library of Congress and has facilities such as tagging and interest groups. This study evaluates whether LibraryThing is a valuable tool for libraries to use for promotional and user engagement purposes. Methodology: This study used a sequential mixed methods 3 phase design: (1) the identification of LibraryThing features for user engagement or promotional purposes, (2) exploratory semi-structured interviews (3) a questionnaire. Findings: Several uses of LibraryThing for promotional and user engagement purposes were identified. The most popular reason libraries used LibraryThing was to promote the library or library stock, with most respondents using it specifically to highlight collections of books. Monitoring of patron usage was low and many respondents had not received any feedback. LibraryThing was commonly reported as being easy to use, remotely accessible, and having low cost, whilst its main drawbacks were the 200 book limit for free accounts, and it being a third-party site. The majority of respondents felt LibraryThing was a useful tool for libraries. Practical implications: LibraryThing has most value as a promotional tool for libraries. Libraries should actively monitor patron usage of their LibraryThing account or request user feedback to ensure that LibraryThing provides a truly valuable service for their library. Orginality : There is little research on the value of LibraryThing for libraries, or librarians perceptions of LibraryThing as a Web 2.0 tool.

O objetivo deste estudo foi avaliar alterações posturais em pacientes com Doença Pulmonar Obstrutiva Crônica (DPOC), por meio do Software para Avaliação Postural (SAPO). Trinta indivíduos constituíram 2 grupos: 15 pacientes com DPOC e 15 idosos saudáveis (controle). Os grupos realizaram espirometria e foram fotografados para avaliação postural. As imagens obtidas foram digitalizadas e, posteriormente, avaliou-se dez alterações posturais com o SAPO [inclinação lateral da cabeça (ILC), desnivelamento dos ombros (DO), desnivelamento pélvico anterior (DPA), inclinação lateral do tronco (ILT), desnivelamento das escápulas (DE), desnivelamento pélvico posterior (DPP), protusão da cabeça (PC), protusão de ombro (PO), báscula anterior da pelve (BAP) e cifose torácica (CT)]. Essas alterações, obtidas no grupo controle, foram conferidas com o padrão de normalidade para adultos jovens, proposto em estudo prévio. Para a comparação das alterações posturais entre grupo controle e DPOC, foi utilizado o teste de Mann-Whitney em grupo controle, e em adultos jovens, o teste t de Student não pareado, ambos com nível de significância estatística de 5%. Dentre as dez alterações posturais, o grupo controle apresentou sete (ILC, DPA, DE, DPP, PC, PO, BAP) com valores angulares significativamente maiores em relação aos adultos jovens. Quando comparados a idosos saudáveis, indivíduos com DPOC apresentaram um aumento significante na angulação de BAP, DPP e CT. Pacientes com DPOC apresentam três alterações posturais que provavelmente estão relacionadas à doença.

Purpose – Linked data is gaining great interest in the cultural heritage domain as a new way for publishing, sharing and consuming data. The paper aims to provide a detailed method and MARiMbA a tool for publishing linked data out of library catalogues in the MARC 21 format, along with their application to the catalogue of the National Library of Spain in the datos.bne.es project. Design/methodology/approach – First, the background of the case study is introduced. Second, the method and process of its application are described. Third, each of the activities and tasks are defined and a discussion of their application to the case study is provided. Findings – The paper shows that the FRBR model can be applied to MARC 21 records following linked data best practices, librarians can successfully participate in the process of linked data generation following a systematic method, and data sources quality can be improved as a result of the process. Originality/value – The paper proposes a detailed method for publishing and linking linked data from MARC 21 records, provides practical examples, and discusses the main issues found in the application to a real case. Also, it proposes the integration of a data curation activity and the participation of librarians in the linked data generation process.

L’encéphalopathie néonatale (EN) affecte plus de 0.8% des nouveau-nés à terme et est la deuxième cause d’handicap neurologique durant l’enfance. Le traitement des enfants atteints d’EN consiste en une prise en charge symptomatique et en l’hypothermie (HT). Néanmoins, plus de 50% des patients traités par HT gardent des séquelles neurologiques majeures. Les données provenant du Canadian Cerebral Palsy Registry montrent que l’HT prévient seulement 4% des cas de paralysie cérébrale (PC). Le fait que l’HT ait des effets neuroprotecteurs chez certains nouveau-nés, mais pas chez tous les nouveau-nés atteints d’EN n’est pas encore totalement élucidé. Il a été rapporté que les nouveau-nés exposés à l’inflammation (sepsis néonatal, infections placentaires) et à l’hypoxie-ischémie (HI) semblent avoir moins d’effets bénéfiques de l’HT que ceux qui ont été seulement exposés à l’HI. Des études précliniques ont établi que l’HT avait des effets neuroprotecteurs dans les cas d’encéphalopathies hypoxique-ischémiques chez les nouveau-nés à terme ou peu prématurés (plus de 35 semaines d’âge gestationnel). Cependant, peu d’études ont investigué les effets de l’HT lorsque l’EN résulte de la combinaison d’HI et d’infection/inflammation, alors qu’il s’agit du scénario pathophysiologique le plus fréquemment rencontré chez les nouveau-nés humains atteints d’EN. Ceci nous a amené à tester les effets neuroprotecteurs de l’HT dans un modèle animal (rat) d’EN induite par l’inflammation et l’HI. Des ratons Lewis au jour postnatal 12 sont injectés avec du lipopolysaccharide (LPS) d’E.coli afin de recréer l’inflammation, puis sont soumis à l’ischémie (ligature de la carotide commune droite) et à l’hypoxie (8% O[indice inférieur 2], 1h30). Les ratons sont ensuite traités ou non par l’HT (32 ± 0.5°C, 4 h). L‘étendue des lésions cérébrales ainsi que les cascades inflammatoires et oxydatives ont été étudiées. Nos résultats montrent que l’HT prévient l’étendue des lésions dans la composante de pénombre ischémique (néocortex et hippocampe). Cet effet neuroprotecteur est indépendant d’un effet anti-inflammatoire cérébral de l’HT portant sur le système de l’interleukine-1. Nos données indiquent que l’HT module l’expression des enzymes responsables de l’élimination des réactifs de l’oxygène (ROS). En conclusion, nos résultats montrent que l'HT a des effets neuroprotecteurs dans un modèle d’EN induite par l’exposition combinée au LPS et à l’HI. Ce projet devrait ouvrir des perspectives translationnelles pour prévenir la PC au-delà de l'hypothermie seule, comme par exemple celle visant à tester le bénéfice de la combinaison thérapeutique d’HT jointe au blocage de cytokines pro-inflammatoires.
