Benchmark, les réseaux sociaux en bibliothèque : étude comparative

Assurer une présence sur les réseaux sociaux est aujourd’hui incontournable pour les bibliothèques d’une certaine taille. Cette démarche permet de toucher un public étendu, d’assurer une médiation vers ses ressources et celles de ses partenaires, de développer la participation des usagers, et de montrer la connexion entre l’établissement et son quartier. La bibliothèque de la Canopée souhaite assurer une forte présence sur les réseaux sociaux.Il en est de même pour la bibliothèque en préfiguration du Carré Saint-Lazare. Cette étude à un instant T doit servir de base pour déterminer quelles sont les plateformes sociales les plus intéressantes dans une bibliothèque de lecture publique. Les fonctionnalités, l’attrait de certains réseaux évoluant à la hausse ou à la baisse entraînera une réévaluation possible de ce benchmark. Etude coordonnée par la préfiguration de la bibliothèque Canopée et rédigée par : Pierre-Marie Augereau, Cyrille Engel, Romain Gaillard, Ophélie Hamot-Béchay, Capucine Liébeaux (préfiguration Canopée), Soizic Cadio (préfiguration Saint-Lazare

Benchmark, les réseaux sociaux en bibliothèque de lecture publique - 2014

Assurer une présence sur les réseaux sociaux est aujourd’hui incontournable pour les bibliothèques d’une certaine taille. Cette démarche permet de toucher un public étendu, d’assurer une médiation vers ses ressources et celles de ses partenaires, de développer la participation des usagers, et de montrer la connexion entre l’établissement et son quartier. La bibliothèque Canopée souhaite assurer une forte présence sur les réseaux sociaux. Il en est de même pour la bibliothèque en préfiguration Saint-Lazare. Cette étude à un instant T doit servir de base pour déterminer quelles sont les plateformes sociales les plus intéressantes dans une bibliothèque de lecture publique. Les fonctionnalités, l’attrait de certains réseaux évoluant à la hausse ou à la baisse entraînera une réévaluation possible de ce benchmark. Après une première édition en juin 2013, cette nouvelle mouture intègre de nouvelles plateformes (Flipboard, Issuu, Snapchat, Flipagram, Libfly) et met à jour l’évaluation des critères pour les autres

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

PET-RAFT Facilitated 3D Printing of Polymeric Materials

Photopolymerization-based 3D printing process is typically conducted using nonliving free radical polymerization, which leads to fabrication of immutable materials. An alternative 3D printing of polymeric materials using trithiocarbonate (TTC) reversible addition-fragmentation chain transfer (RAFT) agents has always been a challenge for material and polymer scientists. Herein we report the first 3D printing of RAFT-based formulations that can be conducted fully open to air using standard digital light processing (DLP) 3D printer and under mild conditions of visible light at blue (λ max = 483 nm, 4.16 mW/cm2) or green (λ max = 532 nm, 0.48 mW/cm2) wavelength. Our approach is based on activation of TTC RAFT agents using eosin Y (EY) as a photoinduced electron-transfer (PET) catalyst in the presence of a reducing agent (tertiary amine), which facilitated oxygen tolerant 3D printing process via a reductive PET initiation mechanism. Re-activation of the TTCs present within the polymer networks enables post-printing monomer insertion into the outer layers of an already printed dormant object under second RAFT process, which provides a new pathway to design a more complex 3D printing. To our best knowledge, this is the first example of open-to-air PET-RAFT facilitated 3D printing of polymeric materials. We believe that our strategy is a significant step forward in the field of 3D printing

3D printing of polymeric materials based on photo-RAFT polymerization

Here, for the first time, we report the 3D printing of polymeric materials via a photo-controlled reversible addition fragmentation chain transfer (photo-RAFT) polymerization process. Our 3D printing resin formulation is based on the use of trithiocarbonate (TTC) RAFT agent, which can mediate radical polymerization via direct photolysis under visible light irradiation (λ = 405 nm). Re-activation of the TTC units within the 3D printed materials enables post-printing transformation
