20 ans d’archivage du web
Authors: Genin Christine 
Published: March 2021

Depuis les premières initiatives de sauvegarde du web à la fin des années 1990 et la création d’un dispositif légal français en 2006, l’archivage du web est une aventure passionnante pour les bibliothécaires. Tout en s’inscrivant dans la tradition du dépôt légal, il confie à des robots la tâche de prendre le relai des êtres humains pour archiver au mieux le web. Les bibliothécaires les nourrissent par des collectes thématiques qui ont pour but de repérer plus précisément les sites qui pourraient échapper à la collecte large. La mise en œuvre du dépôt légal du web a conduit à une évolution du métier de bibliothécaire : définir de nouveaux objets, faire connaître cette mission, baliser les archives du web. Outre les nécessaires adaptations aux évolutions du web, il reste encore de nombreux chantiers à venir, notamment proposer une meilleure indexation des collectes et travailler plus étroitement avec les chercheur·e·s. Le web fait aujourd’hui figure de « mémoire partagée » de l’humanité. Constituer une mémoire de cette mémoire et la partager avec le plus grand nombre est l’un des enjeux les plus importants de notre temps.
Les céramistes d’art, « satellites » du champ artistique
Authors: Bajard Flora 
Published: March 2021

En étudiant l’autonomisation d’un groupe professionnel (les céramistes d’art), cet article donne à voir une conception complémentaire des logiques d’autonomie et d’hétéronomie. Le métier de céramiste d’art en France est très autonome car non seulement différencié des autres activités de création artistique, mais aussi régi par des règles propres et doté de moyens pour perdurer. Il a également la particularité de s’être constitué dans le même temps par attraction envers le champ artistique et par opposition avec son nomos – soit sa loi fondamentale : c’est sur la définition de l’art, reposant notamment sur le critère de non-utilité des œuvres, que se cristallise ce hiatus. Dans un premier temps, l’article montre ainsi que la théorie bourdieusienne des champs et ses corollaires – sous-champ, champ faible, espace hybride, etc. – ne rendent pas totalement compte de cette forme d’autonomie très ambiguë à l’égard du champ artistique ; nous proposons plutôt l’idée d’espace « satellite ». Cette position du groupe professionnel génère de multiples confrontations à des formes d’hétéronomie avec des segments étatiques, qui ont le pouvoir de réitérer ou d’infléchir cette règle centrale du champ artistique. Par le recours au droit, chacune de ces confrontations constitue alors un pari réalisé par des membres du groupe professionnel sur leur capacité à négocier une hétéronomie ajustée à leurs conceptions de l’activité. Ces logiques sociales qui se déploient aux frontières du champ artistique participent simultanément à son renouvellement et à la construction de l’autonomie du groupe professionnel des céramistes d’art.
Les collectifs de scénaristes ou la « fabrique » du métier
Authors: Béliard Anne-Sophie , Lécossais Sarah 
Published: March 2021

Dans un contexte actuel de revalorisation de certains formats télévisuels, les scénaristes de séries télévisées constituent un groupe professionnel en voie de visibilité mais toujours en quête de reconnaissance en France. Cet article propose d’étudier la façon dont les « collectifs », groupes informels de scénaristes professionnels, contribuent à requalifier les pratiques, les identités et les relations professionnelles mêmes de leurs membres. Les résultats présentés s’appuient sur une enquête qualitative en cours composée d’entretiens avec des scénaristes impliqués dans ces collectifs (N=22). L’article montre comment le fonctionnement et la gestion collégiale des collectifs contribuent à faire de ces espaces de discussion, socialement homogènes, des supports de formation. Le collectif contribue à fédérer les auteur·ice·s et à stabiliser leur identité professionnelle en concentrant la réflexion collective qu’ils et elles développent sur leurs compétences d’écriture et sur la mise à distance des logiques individualistes du travail créatif. Les collectifs fournissent, finalement, à leurs membres un soutien à la reconnaissance et à l’autonomie professionnelle dans l’industrie télévisuelle par un effet de labellisation et de rééquilibrage des rapports de pouvoir dans les relations avec les producteurs et les réalisateurs.
« Moi, il me faut du papier »
Authors: Guittet Emmanuelle 
Published: March 2021

L’article interroge conjointement, chez les lecteur·rice·s de romans, les pratiques effectives de lecture numérique et les représentations qui y sont associées, en les mettant en lien avec leur « carrière » de lecteur·rice·s. Il s’appuie sur une enquête qualitative par entretiens (trente-six) menés avec des lecteurs et lectrices de romans. Il présente d’abord les représentations positives associées à la lecture sur liseuse, dont la praticité potentielle est appréciée. Il analyse ensuite les freins au développement de la lecture numérique que peuvent constituer l’attachement à la lecture sur papier, le besoin de posséder et le désir d’exposer les livres. Enfin, l’article étudie les pratiques effectives de lecture sur liseuse et met au jour les déterminismes sociaux expliquant que la structure des pratiques de lecture ne soit pas renouvelée par le recours au numérique, et donc que l’ensemble du lectorat ne soit pas concerné par ces nouvelles pratiques de lecture.
Quand la bande dessinée « tient salon » sur Instagram
Authors: Tréhondart Nolwenn 
Published: March 2021

Scènes littéraires et artistiques émergentes, les réseaux socionumériques sont investis par des écrivains, artistes, amateurs mais aussi par des institutions et industries culturelles, curieuses d’expérimenter des pratiques narratives renouvelant les formes de médiation avec les publics. Tel est le cas de la bande dessinée numérique Été, co-produite par la chaîne publique Arte et la société de community management Bigger Than Fiction, et originellement parue sur Instagram durant les mois de juillet et août 2017 et 2018 à raison d’un ou deux épisodes par jour.Empruntant une démarche sociosémiotique s’intéressant aux processus de négociation engagés entre dispositifs techniques, producteurs-concepteurs culturels et récepteurs, cet article se propose de questionner les formes d’hybridation entre des logiques de création et de narration issues de la bande dessinée et des stratégies de production, de circulation et de réception propres à la plateforme Instagram. L’analyse de l’énonciation éditoriale des pages-écrans d’Été est articulée à une enquête empirique permettant d’éclairer, dans un premier temps, les contraintes de production et de représentation présidant au processus de création (deux entretiens menés avec des concepteurs d’Été), et, dans un second temps, de soulever certains enjeux d’appropriation chez les abonné·e·s-lecteur·rice·s par l’analyse des contenus des commentaires placés en vis-à-vis des illustrations, complétée par une enquête par questionnaire (quatre-vingt-dix réponses).
Patients’ Satisfactions on the Waiting Period at the Emergency Units. Comparison Study before and during Covid-19 Pandemic
Authors: Abdelhadi Abdelhakim 
Published: March 2021

Background This paper analyzes the patients’ experience and satisfaction regarding the waiting period at the emergency unit's hospital before and during the COVID-19 pandemic. Design and methods Brainstorming methodology and data analysis from the public domain used on male and female patients in a private hospital in a middle eastern country. The data analyzed seek the patients’ level of satisfaction about the waiting period before entering the treatment area, inside the treatment area before the doctor's check, and during the rest period after the doctor's visit. The customer's satisfaction is a significant measure during the COVID-19 pandemic, as it may affect the patient's perspective of the facility. A paired t-test at 95% confidence level was conducted. Results and Conclusions The results indicated no difference in satisfaction of the period spent in the emergency room before and during the pandemic.
Outer retina reconstruction following inverted internal limiting membrane flap technique for large macular holes
Authors: Okonkwo Ogugua N. , Hassan Adekunle O. , Gyasi Michael E. , Oderinlo Olufemi 
Published: March 2021

PURPOSE:
The aim of this study is to investigate the outer retina reconstruction using postoperative spectral domain optical coherence tomography (SD OCT) in large diameter macular holes (MHs) treated with the inverted internal limiting membrane (ILM) flap technique.

METHODS:
A retrospective study of 14 consecutive eyes that had vitrectomy and inverted ILM flap technique for MHs with a base diameter of 400 μ or greater. Preoperative and postoperative SD OCT images were assessed for MH closure and for outer retina presence; represented by the external limiting membrane (ELM) and ellipsoid zone (EZ), in the subfoveal and parafoveal areas.

RESULTS:
The average MH base diameter was 963 μ. Postoperative SD-OCT revealed an absence of the outer retina in six eyes, a continuous (regular) presence of the outer retina in four eyes, and a discontinuous (interrupted) presence in four eyes. There was an inverse relationship between MH size and presence or absence of ELM and EZ. A larger MH base diameter size was associated with a higher probability of an absent ELM and EZ (P = 0.04). Eyes in which an outer retina was present postoperatively achieved 6/18 and better vision compared to eyes without (P = 0.08).

CONCLUSION:
The outer retina in some large MHs treated with ILM flap technique can undergo reconstitution and remodeling which improves over time. The average size for MHs with complete reconstitution was 652 μ, 855 μ for those with interrupted reconstitution, and 1242 μ for eyes with no outer retina reconstruction. This suggests that MHs having a size within the limit of the no outer retina reconstitution MH group may be candidates for other surgical techniques in which postoperative outer retina presence is expected.

Developing criteria to assess graduate attributes in students' work for their disciplines
Authors: Chanock Kate 
Published: March 2021

After two decades, efforts to integrate the development and assessment of Ã¢â¬Ëgraduate attributesÃ¢â¬â¢ into discipline curricula remain slow, uneven, and fraught with difficulties.ÃÂ Scholars have identified political, cultural and practical reasons for academicsÃ¢â¬â¢ resistance to this requirement, including Ã¢â¬Ëlack of ownership and shared understanding of how to teach and assess graduate attributesÃ¢â¬â¢ (Radloff et al., 2008). Along with Barrie (2007) and de la Harpe and David (2010), Radloff et al. (2008) have argued that Ã¢â¬Ëacademic staff beliefs are critical and fundamental to any attempts at developing studentsÃ¢â¬â¢ graduate attributesÃ¢â¬â¢.This article suggests that, rather than trying to change these beliefs via top-down mandates to adopt institutional attributes, it may make sense instead to start from academicsÃ¢â¬â¢ beliefs and see what attributes they suggest are actually integral to their cultures of enquiry. I reflect on such a process in the context of developing criteria and standards for assessing graduate Ã¢â¬ËcapabilitiesÃ¢â¬â¢ across the three years of a BA degree, in which a Faculty working party tried to tease out what we meant by Ã¢â¬Ëgood writingÃ¢â¬â¢ into easily applicable criteria with authentic meaning(s) across our varied disciplines.

IntroductionOvarian cancer is the most common malignant cancer among females. This study aimed to investigate role of the CXCL12-CXCR4/CXCR7 chemokine axis in ovarian cancer.Material and methodsSKOV3 cells were transfected with siCXCR4/siCXCR7 plasmids and divided into SKOV3, LV3, LV3-siCXCR4, and LV3-siCXCR7 groups. Cell viability and apoptosis were examined using MTT and flow cytometry. ELISA was conducted to evaluate vascular-endothelial growth factor-A (VEGF-A), interleukin-6 (IL-6), and interleukin-8 (IL-8) levels. SKOV3 cells were transplanted into mice to establish a Xenograft model. The tumour volume of the Xenograft model was recorded. CD31, matrix-metalloprotein-9 (MMP-9), vimentin, and E-cadherin expressions in SKOV3 cells and tumour tissues were evaluated with quantitative real-time PCR (qRT-PCR) and western blot. Immunohistochemistry assay was used to detect VEGF-A, CD31, MMP-9, vimentin, and E-cadherin expression.ResultsSKOV3 cells strongly expressed CXCR4 and CXCR7. CXCL12 significantly enhanced cell viability, and CXCR4/CXCR7 inhibitor remarkably reduced cell viability of SKOV3 (p < 0.05). CXCR4/CXCR7 gene-silencing significantly decreased SKOV3 viability compared to the SKOV3 or LV3 group (p < 0.05). CXCR4/CXCR7 gene-silencing modulated cell cycle and increased apoptosis rates compared to SKOV3 or LV3 group (p < 0.05). CXCR4/CXCR7 gene-silencing inhibited VEGF-1, IL-6, and IL-8 secretion. CXCR4/CXCR7 gene-silencing modulated levels of CD31, MMP-9, vimentin, and E-cadherin. CXCR4/CXCR7 gene-silencing suppressed p-ERK1/2 (p < 0.05) and strengthened inhibitive effects of CXCR4/CXCR7 inhibitor on p-ERK1/2. CXCR4/CXCR7 gene-silencing reduced tumour volume and regulated tumourigenesis-associated molecules in the mouse Xenograft model.ConclusionsCXCR4/CXCR7 gene-silencing could suppress ovarian cancer cell proliferation and tumour growth through modulation of the CXCL12-CXCR4/CXCR7 chemokine axis and mitogen-activated protein kinase (MAPK) signalling pathway.

IntroductionThis study aims to investigate the effects of ivabradine (IVA) on ventricular electrophysiological remodeling after myocardial infarction (MI) in rats.Material and methodsA total of 60 male Sprague-Dawley rats were randomly divided into five groups: an MI group, an IVA group, a metoprolol (MET) group, an IVA + MET group, and a sham group. After a four-week intervention, the ventricular electrophysiological parameters were detected by multichannel electrophysiological polygraph. Then, the morphological characteristics were evaluated using hematoxylin and eosin (H&E) and Masson’s staining, and the expression of phosphorylated connexin 43 (p-Cx43) in the left ventricular wall was detected through immunohistochemistry and the Western blot test.ResultsThe electrophysiological examination revealed that the induction rate and fatality rate of ventricular tachycardia (VT)/ventricular fibrillation (VF) were lower in both the IVA and the MET group, compared with the MI group (6/12, 6/12 vs. 10/11; and 1/12, 1/12 vs. 5/11; all p < 0.05), as well as the IVA + MET group (1/11 vs. 10/11, p < 0.01; and 1/11 vs. 5/11, p < 0.05). The induction rate of VT/VF was lower in the IVA + MET group, compared to the MET group (1/11 vs. 6/12, p < 0.05). H&E and Masson’s staining revealed that compared with the MI group, the left ventricular infarction area was lower in the IVA, MET, and IVA + MET groups (p < 0.05, p < 0.05, and p < 0.01, respectively), while collagen volume fraction (CVF) also was lower in the other groups (all p < 0.01). The left ventricular infarction area and CVF both were lower in the IVA + MET group, compared to the MET group (p < 0.05 and p < 0.01, respectively). The immunohistochemistry and Western blot revealed that p-Cx43 expression was higher in the treatment groups, compared with the MI group (all p < 0.01).ConclusionsIVA can reduce the incidence of ventricular arrhythmia after MI in male rats by improving both structural and electrical remodeling, and the combination of IVA and MET is even more effective.

Published: March 2021

IntroductionChildren with sickle cell disease (SCD) can present a variety of clinical symptoms that may affect their sleep and health-related quality of life (HRQOL). This study aims to investigate the relation between sleep problems and HRQOL in children and adolescents with SCD.Material and methodsThe sample included 86 children and adolescents in the SCD patient group and 82 healthy controls, with an age range of 8-16 years. Subjects for the study were recruited from the Sickle Cell and Thalassemia Center of Hatay State Hospital, Hatay, Turkey. The Children’s Sleep Habits Questionnaire (CSHQ) was used to evaluate sleep problems and Kinder Lebens­qualitätsfragebogen: Children’s Quality of Life Questionnaire – revis­ed (KINDL-R) was used to examine HRQOL.ResultsTotal score, bedtime resistance, and night waking subscores of CSHQ were significantly higher in children with SCD when compared to healthy children. Total score, physical well-being, emotional well-being, social, and school subscores of KINDL-R were significantly lower in the patient group. Among SCD children, total score, bedtime resistance, sleep onset delay, daytime sleepiness, and parasomnias subscores of CSHQ were negatively correlated with KINDL-R total score. In the regression model, disease severity and CSHQ total score had significant negative associations with KINDL-R total score.ConclusionsSleep problems in SCD children appear to be negatively linked with HRQOL. Disease severity and sleep problems may be predictors of overall HRQOL in children and adolescents with SCD.
Progress in caring for cancer patients in the scope of quality of life assessment

Published: March 2021

Quality of life is assessed using standardised general or specific ques­tion­naires. The use of such tools in scientific research makes it possible to determine how the patient functions in specific domains of life, and to measure the overall quality of life and health. A significant step forward in the approach to quality of life assessment is to also take into account factors relating to the patient’s feelings and opinions as well as objective health-related factors. The patient is treated as an entity actively participating in the diagnostic and therapeutic process, whose subjective experiences are important. Research on quality of life assessment constitutes an essential element in the evaluation of the effectiveness of medical technologies. It also represents a new approach to formulating methods of dealing with patients, which is particularly crucial in care for chronically ill patients, including cancer patients.
ATIVIDADE E PARTICIPAÇÃO DE PACIENTES COM ACIDENTE VASCULAR ENCEFÁLICO E SUA CORRELAÇÃO COM A QUALIDADE DE VIDA
Authors: Pinto João Paulo Ferreira , Pernambuco Andrei Pereira 
Published: March 2021

O acidente vascular encefálico (AVE) é definido como uma alteração súbita da função neurológica ocasionada por uma privação de fluxo sanguíneo em determinada área encefálica, isso prejudica o aporte de oxigênio e glicose ao tecido, o que proporciona danos encefálicos que prejudicam a funcionalidade do indivíduo e podem comprometer a qualidade de vida de pessoas acometidas por esta condição. O objetivo deste estudo foi avaliar a atividade e a participação de pacientes acometidos por AVE e correlacioná-los com a qualidade de vida. A amostra foi composta por 20 participantes, de ambos os gêneros e com idade entre 30 e 85 anos, recrutados por conveniência. A análise estatística foi realizada no software GraphPad Prism v5.0. Para verificar a normalidade dos dados foi utilizado o teste de Kolmogorov Smirnov e as análises de correlação foram realizadas por meio do teste de Correlação de Pearson, dada a distribuição normal dos dados. Os resultados demonstram que os pacientes com AVE possuem níveis de atividade 4,45 ± 1,79, níveis de participação 12,90 ± 4,38 e de qualidade de vida 143,9 ± 38,39. As análises de correlação apontam que as variáveis atividade e participação (r Pearson = 0,64, p = 0,002); atividade e QV (r Pearson = 0,54, p = 0,01) e participação e QV (r Pearson = 0,75, p = 0,0001) se correlacionam significativa e positivamente. Por fim o teste de regressão múltipla demonstrou que a variável participação explica em 56% a QV dos participantes do estudo. Diante dos resultados obtidos no presente estudo, pode ser observado, que a idade não altera a participação, atividade e nem a QV, porém, a atividade e a participação interferem diretamente sobre a QV. Deste modo as intervenções fisioterapêuticas devem focar tanto a atividade quanto a participação dos indivíduos com AVE para aprimorar não só a função como também a qualidade de vida destas pessoas.
Pengaruh Pemberian Pupuk Npk Mutiara Terhadap Pertumbuhan dan Produksi Tanaman Jagung (Zea Mayz L)

Published: March 2021

Berdasarkan hasil Uji BNJ (Beda Nyata Jujur) pada table 1 menunjukan bahwa perlakuan NPK Mutiara P5 (180 gr/petak) diperoleh bahwa rata-rata pertumbuhan tinggi tanaman jagung bervariasi. Pertumbuhan tinggi tanaman jagung memberikan nilai rata-rata pada 14 HST sebesar 40,84 cm, 28 HST sebesar 106,16 cm dan 42 HST sebesar 196,72 cm berbeda sangat nyata dengan P0 (konrol), P1 (60 gr/petak), P2 (90 gr/petak), P3 (120 gr/petak) sedangkan dengan perlakuan P4 (150 gr/petak) tidak berbeda nyata. Hal ini disebabkan kebutuhan tanaman masih memanfaatkan unsur hara yang tersedia di dalam tanah. Dengan adanya peningkatan dosis pupuk NPK Mutiara Semakin meningkat dosis pupuk, maka terjadi kenaikan pertumbuhan tinggi tanaman, oleh karena itu bahwa dengan semakin dewasanya tanaman, maka sistim perakaran telah berkembang dengan baik dan lengkap, sehingga tanaman semakin mampu menyerap unsur hara dalam bentuk anion dan kation yang mengandung unsur N, P dan K yang terdapat pada pupuk Mutiara tersebut.
