PATRICE DESBIENS : CONSÉCRATION ET ESTHÉTIQUE DE LA PAUVRETÉ1
Authors: Hotte Lucie 
Published: October 2019

Reconnu comme un des plus importants poètes franco-ontariens, Patrice Desbiens n’a pourtant pas remporté d’importants prix littéraires. Cet article explique cet écart entre la notoriété de l’auteur et sa consécration par une analyse de sa réception critique qui oscille entre l’éloge sans retenue et la critique virulente. Il montre que les choix esthétiques du poète — qui privilégie ce que l’autrice appelle une « esthétique de la pauvreté » — contribuent à cette réception mitigée.
L’après-mobilisation : le Mouvement du 20 Février au Maroc, de la désillusion au redéploiement de l’engagement
Authors: Beauchesne Pierre-Luc 
Published: October 2019

Cet article analyse l’impact du Mouvement du 20 Février (M20F) au Maroc qui émerge dans le sillage des soulèvements arabes de 2011 en se focalisant sur le devenir des participants dans l’après-mobilisation. L’essoufflement de la dynamique protestataire et la mise en veille du mouvement ont pu s’accompagner d’un sentiment de désillusion chez les militants. Ce sentiment n’a pas que favorisé la démobilisation, mais aussi le redéploiement de l’engagement à d’autres échelles, suivant d’autres temporalités, vers les « structures de rémanence » (abeyance structures) de l’espace protestataire. L’épreuve du M20F a indéniablement marqué une génération de militants qui s’inscrivent dans la continuité des combats de leurs aînés, mais qui veulent faire entendre une autre voix dans les espaces protestataires comme dans les arènes de la politique instituée.
Lutte de pouvoir au sein du musée d’art entre la conservation et l’éducation
Authors: Lemay-Perrault Rébéca , Paquin Maryse 
Published: October 2019

Cet article porte sur la lutte de pouvoir entre la conservation et l’éducation au sein du musée d’art, où l’un désire donner toute la place aux oeuvres, et l’autre stimuler l’apprentissage au moyen des médiations. Il s’agit d’un débat séculaire qui évolue sous la pression tant économique, qui consiste à attirer toujours de plus en plus de visiteurs au musée, qu’idéologique, avec la montée des médiations qui s’imposent dorénavant comme modèles de transmission culturelle dans les sociétés postindustrialisées. Depuis plus d’un siècle, les musées d’art sont le lieu d’un débat portant sur la place des médiations autour des oeuvres, entre les tenants de l’esthétique et ceux de l’éducation. Au regard de l’histoire, ils en transforment radicalement l’usage, que l’on se tienne d’un côté ou de l’autre des protagonistes. Entre les deux positions, Bourdieu et Darbel jettent un pavé dans la mare d’un milieu de l’éducation muséale de l’art marqué par le principe de la distinction, de même que du « choc esthétique » de Malraux, en montrant que l’expérience esthétique découle de la compréhension des oeuvres et de la connaissance des codes culturels. Toutefois, il ne s’agit là que d’un épisode de plus dans une saga séculaire. D’un côté, derrière l’absence de clés de lecture se cache la participation à une dynamique perverse, celle de l’exclusion sociale des publics néophytes qui ne peuvent accéder à la délectation. De l’autre, derrière la montée de l’éducation muséale de l’art se cache la frustration des publics connaisseurs qui voient leur expérience esthétique entravée par une interprétation nécessairement réductrice des sens de l’oeuvre. Aujourd’hui, au centre de ce débat, des tensions existent toujours entre les conservateurs et les éducateurs, écartelés entre les exigences de développement de nouveaux publics et celles des habitués, les collectionneurs, les artistes et le marché de l’art. Ceux-ci garantissent au musée un statut dans les réseaux de l’art, et de l’art contemporain en particulier. Ces exigences tournent autour de la question suivante : jusqu’où une institution muséale peut-elle aller dans le déploiement de dispositifs de médiation facilitant l’interprétation des oeuvres chez les publics néophytes, et ce, sans entraver l’expérience esthétique du regardeur habitué ou expert ?
Géopolitique du musée : les enjeux de la fréquentation
Authors: Mairesse François 
Published: October 2019

Les classements de musées en fonction de leur fréquentation (nombre de visiteurs, mais aussi nombre defollowerssur Internet) présentent une image particulièrement révélatrice des rapports de force en train de se dessiner sur l’échiquier mondial : les pays occidentaux y assurent, du fait que les principaux musées superstars y sont situés, une position encore dominante, mais des évolutions sont perceptibles, illustrant la concurrence que les pays ou les villes et régions qui les composent se livrent afin de développer leur propre économie. À travers l’analyse proposée dans cet article se dessine une réflexion qui peut être abordée de manière géopolitique, montrant l’influence encore forte d’une certaine idée de la culture occidentale, mais aussi les transformations actuelles considérables des rapports de pouvoir qui lui sont liés.
Les politiques muséales au Québec
Authors: Paquette Jonathan 
Published: October 2019

Tel que nous le connaissons aujourd’hui, en tant qu’institution, le musée émerge dans la seconde moitié du XVIIIe siècle. Depuis, l’État a développé des rapports avec cette institution, rapports qui se sont transformés et renouvelés selon les époques. Les transformations des politiques muséales révèlent les ruptures ainsi que les nouveaux usages et la rationalité politique du musée. Cet article a pour objectif de mettre en lumière l’évolution de la rationalité politique de l’action de l’État québécois dans le secteur muséal. Les rapports entre État et musées au Québec se sont configurés autour de trois périodes charnières. Dans un premier temps (1836-1919), le musée s’est révélé d’une utilité pour l’État québécois en favorisant sa maîtrise du territoire. Dans un deuxième temps (1919-1984), les politiques muséales du Québec ont fait du musée un service public, voué à la préservation et à l’accessibilité du patrimoine. La politique des musées nationaux a fait de l’institution un instrument des aspirations culturelles de l’État québécois. Or, les nouveaux rapports qui se sont développés plus récemment (1984-2013) illustrent plutôt une rupture dans la logique d’intervention de l’État, qui reconstruit son intervention sur une base sectorielle et diffuse, en prenant un rôle secondaire en matière d’orientations culturelles du secteur.

Authors: Martinelli Nicolò , Spreafico Andrea , Tramacere Irene , Marcolli Daniele , Valli Federico , Curci Domenico 
Published: October 2019

Background:
Sever's disease is a common cause of pain in growing kids. Many papers reported in the literature discuss this pathologic condition, but no consensus regarding its etiology has been found among researchers. The aim of the present study was to describe the epidemiologic profile and associated factors of 430 athletic children in a population-based sample of soccer (29.5%), basketball (48.1%), and volleyball (22.3%) players aged 6 to 14 years.

Methods:
Every athlete was evaluated through physical examination, the Foot Posture Index (FPI), the Oxford Ankle Foot Questionnaire, and a custom-made sports questionnaire.

Results:
These data show that body mass index, sex, terrain type, sports discipline, and FPI should not be considered as risk factors for calcaneal apophysitis, whereas a significantly higher risk has been found in younger individuals (P < .01), in those with fewer training sessions per week (P = .02), and in those with shorter training sessions (P < .01).

Conclusions:
The prevalence of Sever's disease in the athletic children evaluated in the present study was higher in younger and less active patients, whereas no differences were registered by sex, FPI, body mass index, terrain type, or sports discipline.
Evidence for a non-linear carbon accumulation pattern along an Alpine glacier retreat chronosequence in Northern Italy

Published: October 2019

BackgroundThe glaciers in the Alps, as in other high mountain ranges and boreal zones, are generally retreating and leaving a wide surface of bare ground free from ice cover. This early stage soil is then colonized by microbes and vegetation in a process of primary succession. It is rarely experimentally examined whether this colonization process is linear or not at the ecosystem scale. Thus, to improve our understanding of the variables involved in the carbon accumulation in the different stages of primary succession, we conducted this research in three transects on the Matsch glacier forefield (Alps, N Italy) at an altitude between 2,350 and 2,800 m a.s.l.MethodsIn three field campaigns (July, August and September 2014) a closed transparent chamber was used to quantify the net ecosystem exchange (NEE) between the natural vegetation and the atmosphere. On the five plots established in each of the three transects, shading nets were used to determine ecosystem response function to variable light conditions. Ecosystem respiration (Reco) and gross ecosystem exchange (GEE) was partitioned from NEE. Following the final flux measurements, biometric sampling was conducted to establish soil carbon (C) and nitrogen (N) content and the biomass components for each transect.ResultsA clear difference was found between the earlier and the later successional stage. The older successional stages in the lower altitudes acted as a stronger C sink, where NEE, GEE and Reco were significantly higher than in the earlier successional stage. Of the two lower transects, the sink capacity of intermediate-succession plots exceeded that of the plots of older formation, in spite of the more developed soil. Total biomass (above- and belowground) approached its maximum value in the intermediate ecosystem, whilst the later stage of succession predominated in the corresponding belowground organic mass (biomass, N and C).OutlookWe found that the process of carbon accumulation along a glacier retreat chronosequence is not linear, and after a quite rapid increase in carbon accumulation capacity in the first 150 years, in average 9 g C m−2year−1, it slows down, taking place mainly in the belowground biomass components. Concurrently, the photosynthetic capacity peaks in the intermediate stage of ecosystem development. If confirmed by further studies on a larger scale, this study would provide evidence for a predominant effect of plant physiology over soil physical characteristics in the green-up phase after glacier retreat, which has to be taken into account in the creation of scenarios related to climate change and future land use.

Published: October 2019

Background
The preferences of Web users can be influenced by distinct factors of populations. Hence, hypothetically, source-based patterns of health-related Web searches might differ between individuals from developed and developing countries, due to their distinct educational, social, economic, political, cultural, and psychosocial backgrounds. In this context, this study aimed to determine the trends of toothache-related searches performed on Google Search and YouTube, regarding differences between developed and developing countries.

Methods
This retrospective longitudinal study analyzed computational metadata on toothache-related interests of Internet users. Google Trends was accessed to obtain the monthly variation of relative search volume (RSV) of the topic “Toothache-Disease” on Google (G) and YouTube (YT) through 2008–2017. Autocorrelation and partial autocorrelation plots, ARIMA models, Kruskal–Wallis, Dunn’s and T tests were performed for evaluating trends, 12-month forecasts and the differences of annual ratios of YT/G searches between developed and developing countries, respectively (P < 0.05).

Results
Uptrends of RSVs were observed in both country groups over time, although 12-month forecasts tended to plateau.The volumes of searches were higher in developed countries in comparison to developing ones; however, this difference was not observed regarding Google searches performed between 2016 and 2017. Independently of country groups, the ratios YT/G remained relatively constant throughout the period, indicating a greater interest in toothache-related information available on Google.

Conclusion
In conclusion, toothache-related searches from Google and YouTube increased during the last decade. The preferences of Web users seemed to be influenced by the differences between developed and developing countries, such as the availability and penetration of the Internet, and education levels.
Relationship between tumor size and metastatic site in patients with stage IV non-small cell lung cancer: A large SEER-based study
Authors: Shan Qinge , Fan Yanling , Guo Jun , Han Xiao , Wang Haiyong , Wang Zhehai 
Published: October 2019

Objective
To analyze the relationship between tumor size and metastatic site in stage IV NSCLC patients.

Methods
A total of 40,196 stage IV NSCLC patients from 2010 to 2015 were screened by SEER database. Chi-square test was used to compare the characteristics of clinical variables. At the same time, multivariate Logistic regression analysis was used to evaluate the relationship between tumor size and organ metastasis.

Results
Regardless of tumor size, the proportion of bone metastasis and lung metastasis was higher and similar in patients with squamous cell carcinoma, while in patients with adenocarcinoma, bone metastasis accounted for the highest proportion. We found that whether the metastatic site was bone, brain, liver or lung, the proportion of patients with a tumor size of 3–7 cm was the highest. Multivariate regression analysis demonstrated that patients with a tumor size of 3–7 cm and a tumor size ≥7 cm were more likely to develop brain metastasis and lung metastasis compared with patients with a tumor size ≤3 cm (all P < 0.001), which meant the larger the tumor, the greater the risk of brain or lung metastasis. At the same time, the results indicated that patients with a tumor size of 3–7 cm had a tendency to develop liver metastasis (P = 0.004), while the statistical significance was not found for patients with a tumor size ≥7 cm (P = 0.524). The results also revealed that patients with a tumor size of 3–7cm had no significant difference to develop bone metastasis (P = 0.116), while the statistical significance was found for patients with a tumor size ≥7 cm (P < 0.001).

Conclusions
There was statistical significance between tumor size and metastatic site in patients with stage IV NSCLC. For brain or lung metastasis, the larger the tumor, the higher the risk of brain or lung metastasis. For liver metastasis, patients with a tumor size of 3–7 cm were more prone to develop liver metastasis. For bone metastasis, patients with a tumor size ≥7 cm were more likely to have bone metastasis.
Self‐Healing Polymers Based on Coordination Bonds
Authors: Li Cheng‐Hui , Zuo Jing‐Lin 
Published: October 2019

AbstractSelf‐healing ability is an important survival feature in nature, with which living beings can spontaneously repair damage when wounded. Inspired by nature, people have designed and synthesized many self‐healing materials by encapsulating healing agents or incorporating reversible covalent bonds or noncovalent interactions into a polymer matrix. Among the noncovalent interactions, the coordination bond is demonstrated to be effective for constructing highly efficient self‐healing polymers. Moreover, with the presence of functional metal ions or ligands and dynamic metal–ligand bonds, self‐healing polymers can show various functions such as dielectrics, luminescence, magnetism, catalysis, stimuli‐responsiveness, and shape‐memory behavior. Herein, the recent developments and achievements made in the field of self‐healing polymers based on coordination bonds are presented. The advantages of coordination bonds in constructing self‐healing polymers are highlighted, the various metal–ligand bonds being utilized in self‐healing polymers are summarized, and examples of functional self‐healing polymers originating from metal–ligand interactions are given. Finally, a perspective is included addressing the promises and challenges for the future development of self‐healing polymers based on coordination bonds.

Published: October 2019

AbstractAs technologically important materials for solid‐state batteries, Li super‐ionic conductors are a class of materials exhibiting exceptionally high ionic conductivity at room temperature. These materials have unique crystal structural frameworks hosting a highly conductive Li sublattice. However, it is not understood why certain crystal structures of the super‐ionic conductors lead to high conductivity in the Li sublattice. In this study, using topological analysis and ab initio molecular dynamics simulations, the crystal structures of all Li‐conducting oxides and sulfides are studied systematically and the key features pertaining to fast‐ion conduction are quantified. In particular, a unique feature of enlarged Li sites caused by large local spaces in the crystal structural framework is identified, promoting fast conduction in the Li‐ion sublattice. Based on these quantified features, the high‐throughput screening identifies many new structures as fast Li‐ion conductors, which are further confirmed by ab initio molecular dynamics simulations. This study provides new insights and a systematic quantitative understanding of the crystal structural frameworks of fast ion‐conductor materials and motivates future experimental and computational studies on new fast‐ion conductors.
The collective trolling lifecycle
Authors: Sun Lia H. , Fichman Pnina 
Published: October 2019

AbstractAlthough collective trolling is an integral part of online communities, it has received little scholarly attention. Research on collective trolling, which involves an organized group trolling effort, is in its infancy perhaps because early works on online trolling depicted it as the deviant behavior of individuals who acted in isolation and under hidden identity. Thus, it is still unclear what collective trolling is and how it evolves. To address this gap, we collected 12,840 posts and comments pertinent to a brief, controversial, and very visible collective trolling event. The event, which surrounded Chinese rapper PG One on the Chinese microblogging platformSina Weibo, received 40 million reads in 1 day and a lot of media attention. Based on a thematic content analysis of 480 posts, we describe the collective trolling lifecycle through five distinct stages defined by posting frequency and content of posts. We also explain the transformation of participants' roles, tactics, motives, behavioral tone, and the variations in their thematic content, stakeholder group affiliation, and roles over time. The major contributions of the study are the characterization of collective trolling, and the addition of a lifecycle model to the understanding of trolling as sociotechnical, context‐dependent, and multidimensional phenomenon.
Interactive faceted query suggestion for exploratory search: Whole‐session effectiveness and interaction engagement
Authors: Ruotsalo Tuukka , Jacucci Giulio , Kaski Samuel 
Published: October 2019

AbstractThe outcome of exploratory information retrieval is not only dependent on the effectiveness of individual responses to a set of queries, but also on relevant information retrieved during the entire exploratory search session. We study the effect of search assistance, operationalized as an interactive faceted query suggestion, for both whole‐session effectiveness and engagement through interactive faceted query suggestion. A user experiment is reported, where users performed exploratory search tasks, comparing interactive faceted query suggestion and a control condition with only conventional typed‐query interaction. Data comprised of interaction and search logs show that the availability of interactive faceted query suggestion substantially improves whole‐session effectiveness by increasing recall without sacrificing precision. The increased engagement with interactive faceted query suggestion is targeted to direct situated navigation around the initial query scope, but is not found to improve individual queries on average. The results imply that research in exploratory search should focus on measuring and designing tools that engage users with directed situated navigation support for improving whole‐session performance.

Published: October 2019

AbstractThis article provides an analysis of theories and methodologies that have been applied in citizen science research. This study suggests a significant contribution of citizen science to various disciplines as well as overall science education, literacy, and development. A solid theoretical grounding of citizen science research, coupled with application of pertinent emergent theories to various processes associated with scientific inquiry and discovery, suggests the disciplinary traits and unique contributions. This study proposes that the current pace of citizen science research, empowered by ordinary citizens as well as technological affordances, provides solid evidence to warrant further development of citizen science as a unique discipline that can strengthen and democratize scientific inquiry.
Metabolic Incorporation of N‐Acetyl Muramic Acid Probes into Bacterial Peptidoglycan

Published: October 2019

AbstractBacterial cells utilize small carbohydrate building blocks to construct peptidoglycan (PG), a highly conserved mesh‐like polymer that serves as a protective coat for the cell. PG production has long been a target for antibiotics, and its breakdown is a source for human immune recognition. A key component of bacterial PG, N‐acetyl muramic acid (NAM), is a vital element in many synthetically derived immunostimulatory compounds. However, the exact molecular details of these structures and how they are generated remain unknown due to a lack of chemical probes surrounding the NAM core. A robust synthetic strategy to generate bioorthogonally tagged NAM carbohydrate units is implemented. These molecules serve as precursors for PG biosynthesis and recycling. Escherichia coli cells are metabolically engineered to incorporate the bioorthogonal NAM probes into their PG network. The probes are subsequently modified using copper‐catalyzed azide‐alkyne cycloaddition to install fluorophores directly into the bacterial PG, as confirmed by super‐resolution microscopy and high‐resolution mass spectrometry. Here, synthetic notes for key elements of this process to generate the sugar probes as well as streamlined user‐friendly metabolic labeling strategies for both microbiology and immunological applications are described. © 2019 by John Wiley & Sons, Inc.Basic Protocol 1: Synthesis of peracetylated 2‐azido glucosamineBasic Protocol 2: Synthesis of 2‐azido and 2‐alkyne NAMBasic Protocol 3: Synthesis of 3‐azido NAM methyl esterBasic Protocol 4: Incorporation of NAM probes into bacterial peptidoglycanBasic Protocol 5: Confirmation of bacterial cell wall remodeling by mass spectrometry
