Background. Endoscopic septostomy is a secure and reliable endoscopic for treating multiloculated hydrocephalus. The ventriculoperitoneal (VP) shunt procedure is known as the gold standard. However, shunt malfunction often occurs. The combination of these has been reported to reduce the incidence of recurrent malfunction and reestablish communication between isolated intraventricular compartments making a special ventricular cavity. Case presentation. A one-year-old child who had previously communicated hydrocephalus complained of vomiting, appeared agitated, and had difficulty falling asleep. The patient had a history of congenital diseases. The patient had VP shunt Keen dextra and sinistra fitted to manage the hydrocephalus before, but one side of the VP shunt was found to be malfunctioning. Physical examination revealed a sunset eye phenomenon with a head circumference of 48 cm dry and clean ventricular parietal shunt surgery scars. The findings of the multiloculated cystic lesions on the endoscopic, agenesis of the septum pellucidum, and dysgenesis of the corpus callosum. Discussion. The patient was scheduled for endoscopic cyst fenestrations surgery, endoscopic third ventriculostomy (ETV), VP shunt Kocher dextra low pressure, and aff VP shunt Keen dextra that was evaluated with preoperative and postoperative CT scans which showed the sulcus and gyrus prominent had improved, slightly open in fissure Sylvie, reduced size in ventricular (the average decrease was 5 cm3) that decreased intracranial pressure which improved the patient’s quality of life. Conclusion. Endoscopy septostomy and VP shunt are a great combination to treat multiloculated hydrocephalus and VP shunt malfunction.

Background. Minimal change disease (MCD) and focal segmental glomerulosclerosis (FSGS) are two common forms of childhood nephrotic syndrome (NS). Separating MCD from FSGS is essential to determine the treatment therapy and the prognosis. Cluster of differentiation 80 (CD80) in urine is now considered a valuable marker for detecting MCD. Therefore, we conducted this research to evaluate the role of urinary CD80 concentrations in differentiating MCD from FSGS. Methods. A cross-sectional descriptive study was performed on 67 children with NS who underwent kidney biopsy and 67 children in the control group. Results. MCD accounted for the majority (61.2%), while FSGS accounted for 38.8% with an MCD/FSGS ratio of 1.6:1. There were no significant differences in age, gender, hematuria, hypertension, urinary protein-creatinine ratio, and albumin concentrations between the two study groups (p>0.05). There were statistically significant differences in glomerular filtration rate (GFR) between the two study groups with p<0.05. The urinary CD80/creatinine ratio in the MCD group was 25.6 (5.4-38.3) pg/µmol, which was significantly higher than that of the FSGS group (3.6 (1.9-6.5) pg/µmol) with p<0.05. The area under the ROC curve for urinary CD80/creatinine ratio in the diagnosis of MCD with FSGS was 0.87 (95% CI 0.79-0.95) at a cut-off value of 4.6 pg/µmol, with a sensitivity of 85.4% and specificity of 73.1%, p<0.05. Conclusion. The urinary CD80/creatinine ratio was useful in differentiating between nephrotic syndrome with MCD and FSGS.

MEASURING THE TECHNOLOGICAL COMPETITIVENESS OF ECONOMIES WITH THE PTCE METHOD: PRC VS. USA 2000–2020
Authors: Woźnicki Adam , Gawlik Remigiusz
Published: July 2024

The relationship between China (PRC) and the United States (USA) has reached an unprecedented level of tension, mainly due to economic and technological rivalry. This study introduces an original quantitative method, the Pentagon of Technological Competitiveness of Economy (PTCE) to measure the technological competitiveness of both countries from 2000 to 2020. The findings reveal that while the USA remains a global technological leader, the PRC is emerging as a formidable challenger. Although the USA still holds the lead, signs of decline are visible, while the PRC exhibits a remarkable upward trajectory in technological competitiveness. The findings provide actionable recommendations for policymakers. To reinforce its position as the unrivaled technological leader, the USA should prioritize enhancing capabilities in areas such as patents, scientific articles and the export of high technology and STEM-related products. For the PRC there is an unprecedented opportunity to surpass the USA in technological leadership by strategic investments in research, innovation and human capital development. The novelty of this research lies in two main areas: (i) its significant contribution to competitiveness analysis through the introduction of the PTCE method and (ii) its provision of a comprehensive assessment of the shifting technological dynamics between the USA and the PRC.
Convective Overstability in Radially Global Protoplanetary Disks. I. Pure Gas Dynamics
Authors: Lehmann Marius , Lin Min-Kai
Published: July 2024

Protoplanetary disks are prone to several hydrodynamic instabilities. One candidate, convective overstability (COS), can drive radial semiconvection that may influence dust dynamics and planetesimal formation. However, the COS has primarily been studied in local models. This paper investigates the COS near the midplane of radially global disk models. We first conduct a global linear stability analysis, which shows that linear COS modes exist only radially inward of their Lindblad resonance (LR). The fastest-growing modes have LRs near the inner radial domain boundary with effective radial wavelengths that can be a substantial fraction of the disk radius. We then perform axisymmetric global simulations and find that the COS’s nonlinear saturation is similar to previous incompressible shearing box simulations. In particular, we observe the onset of persistent zonal and elevator flows for sufficiently steep radial entropy gradients. In full 3D, nonaxisymmetric global simulations, we find the COS produces large-scale, long-lived vortices, which induce the outward radial transport of angular momentum via the excitation of spiral density waves. The corresponding α-viscosity values of order 10−3 agree well with those found in previous 3D compressible shearing box simulations. However, in global disks, significant modifications to their radial structure are found, including the formation of pressure bumps. Interestingly, the COS typically generates an outward radial mass transport, i.e., decretion. We briefly discuss the possible implications of our results for planetesimal formation and for interpreting dust rings and asymmetries observed in protoplanetary disks.
Violent Starbursts and Quiescence Induced by Far-ultraviolet Radiation Feedback in Metal-poor Galaxies at High Redshift

Published: July 2024

JWST observations of galaxies at z ≳ 8 suggest that they are more luminous and clumpier than predicted by most models, prompting several proposals on the physics of star formation and feedback in the first galaxies. In this paper, we focus on the role of ultraviolet (UV) radiation in regulating star formation by performing a set of cosmological radiation hydrodynamics simulations of one galaxy at subparsec resolution with different radiative feedback models. We find that the suppression of cooling by far-UV (FUV) radiation (i.e., H2 dissociating radiation) from Population II stars is the main physical process triggering the formation of compact and massive star clusters and is responsible for the bursty star formation observed in metal-poor galaxies at z ≳ 10. Indeed, artificially suppressing FUV radiation leads to a less intense continuous mode of star formation distributed into numerous but low-mass open star clusters. Due to the intense FUV field, low-metallicity clouds remain warm (∼104 K) until they reach a relatively high density (≳103 cm−3), before becoming self-shielded and transitioning to a colder (∼100 K), partially molecular phase. As a result, star formation is delayed until the clouds accumulate enough mass to become gravitationally unstable. At this point, the clouds undergo rapid star formation, converting gas into stars with high efficiency. We therefore observe exceptionally bright galaxies (10 times brighter than for continuous star formation) and subsequent quenched “dead” galaxies that did not form stars for tens of Myr.

Four new species of Russula subsect. Cyanoxanthinae, viz. Russula atrochermesina Y.L. Chen & J.F. Liang, R. lavandula Y.L. Chen, B. Chen & J.F. Liang, R. lilaceofusca Y.L. Chen & J.F. Liang and R. perviridis Y.L. Chen, B. Chen & J.F. Liang, from China are proposed, based on morphological and molecular evidence. Russula atrochermesina can be distinguished by its violet pileus with tuberculate-striate margin, distant lamellae that stain greyish-yellow when bruised, basidiospores ornamented by isolated warts, wide hymenial cystidia on lamellae edges, cystidia content negative reaction in sulphovanillin and branched subterminal cells in pileipellis. Russula lavandula has a purplish-white to violet red pileus with a yellow centre, frequently present lamellulae and furcations, stipe often with pale yellow near the base, isolated basidiospores ornamentation and unbranched cuticular hyphal terminations, while R. lilaceofusca is characterised by its lilac brown to dark brown pileus, crowded lamellae with lamellulae and furcations, stipe often turning reddish-yellow when bruised, subreticulate basidiospores ornamentation and clavate hymenial cystidia often with capitate appendage whose contents that change to reddish-black in sulphovanillin. Russula perviridis is characterised by its large basidiomata, smooth pileus surface, frequently present lamellulae and furcations, stipe with yellow-brown tinge, globose to broadly ellipsoid basidiospores with subreticulate ornamentation, long hymenial cystidia that turn greyish-black in sulphovanillin and symbiotic with Quercus semecarpifolia. Phylogenetic analyses, based on multi-gene ITS+LSU+mtSSU+rpb2, indicate that R. atrochermesina, R. lavandula, R. lilaceofusca and R. perviridis are closely related to R. pallidirosea and R. purpureorosea, R. banwatchanensis, R. lakhanpalii and R. nigrovirens, respectively.
Sénégal. Fortune et infortune du « dialogue social »
Authors: Cissokho Sidy
Published: July 2024

Depuis les années 2000, le Sénégal s’est doté d’un vaste ensemble d’institutions au sein desquelles le « dialogue social » entre travailleurs, employeurs et État doit avoir lieu. Cette architecture vient encadrer des relations entre le pouvoir et le mouvement syndical longtemps marquées par une forte proximité. La mise en place de ce dispositif exclut cependant la plus grande partie des actifs et leurs représentants, au premier rang desquels les travailleurs de l’informel. Elle aboutit à la coexistence de deux circuits de négociation : l’un, officiel, dédié à une minorité de représentants syndicaux et de travailleurs salariés ; et l’autre, officieux, dans lequel évolue la grande majorité.
Le rire d’admiration : la joie chrétienne
Authors: de Saxcé Anne
Published: July 2024

La modernité lie le rire à la passion fondamentale de l’admiration en soulignant le rôle de la surprise, ce qui permet d’aboutir, selon un schéma mécaniste, à l’idée que le rire soit causé par le sentiment d’un ridicule. Mais ne s’étonne-t-on que de ce qui est risible et ridicule ? Il existe une tradition patristique − Augustin, et Grégoire le Grand − qui lie le rire à l’admiration comprise cette fois comme l’expression d’une joie devant la grandeur de Dieu. Les auteurs médiévaux se sont ensuite demandé si l’on rirait vraiment dans la vie éternelle .

Published: July 2024

Depuis les années 1990, les lieux d’accueil enfants-parents (Laep) ont connu une trajectoire d’institutionnalisation et se sont fortement déployés sur le territoire français. Il s’agit d’un dispositif de soutien à la parentalité dont les pratiques concrètes des accueillantes constituent des perspectives de recherche renouvelées. À partir d’une enquête qualitative menée en 2021 dans six Laep de deux départements de France métropolitaine, cette recherche, conjuguant observations et entretiens auprès des intervenants et des parents lors de temps d’accueil, s’intéresse à la manière dont les accueillantes appréhendent et façonnent le cadre du Laep, qui s’inscrit dans une mission de prévention et qui est soumis, selon le référentiel institué par la branche Famille de la Caisse nationale des Allocations familiales (Cnaf), à une exigence de neutralité. L’article propose une analyse typologique de quatre modalités d’intervention (accueillir les enfants et les parent ; filtrer les jugements normatifs ; induire, en invitant les familles à adopter certaines postures parentales tout en respectant leur autonomie d’action ; et conseiller par des suggestions fondées sur des connaissances considérées comme légitimes) à travers lesquelles s’articulent visée préventive et exigence de neutralité.
A Dual-channel Progressive Graph Convolutional Network via subgraph sampling
Authors: Guan Wenrui , Wang Xun
Published: July 2024

Graph Convolutional Networks (GCNs) demonstrate an excellent performance in node classification tasks by updating node representation via aggregating information from the neighbor nodes. Note that the complex interactions among all the nodes can produce challenges for GCNs. Independent subgraph sampling effectively limits the neighbor aggregation in convolutional computations, and it has become a popular method to improve the efficiency of training GCNs. However, there are still some improvements in the existing subgraph sampling strategies: 1) a loss of the model performance caused by ignoring the connection information among different subgraphs; and 2) a lack of representation power caused by an incomplete topology. Therefore, we propose a novel model called Dual-channel Progressive Graph Convolutional Network (DPGCN) via sub-graph sampling. We construct subgraphs via clustering and maintain the connection information among the different subgraphs. To enhance the representation power, we construct a dual channel fusion module by using both the geometric information of the node feature and the original topology. Specifically, we evaluate the complementary information of the dual channels based on the joint entropy between the feature information and the adjacency matrix, and effectively reduce the information redundancy by reasonably selecting the feature information. Then, the model convergence is accelerated through parameter sharing and weight updating in progressive training. We select 4 real datasets and 8 characteristic models for comparison on the semi-supervised node classification task. The results verify that the DPGCN possesses superior classification accuracy and robustness. In addition, the proposed architecture performs excellently in the low labeling rate, which is of practical value to label scarcity problems in real cases.

Mixed reality learning spaces for collaborative experimentation: A challenge for engineering education and training
Authors: Müller Dieter , Bruns F. Wilhelm , Erbe Heinz-Hermann , Robben Bernd , Yoo Yong-Ho
Published: July 2024

Although the vast majority of research in human-computer interaction involves only our senses of sight and hearing, with sporadic forays into touch, future laboratories used in engineering education will mostly benefit from developments beyond video and sound. Tangible and embedded interaction, augmented and mixed reality characterizes ultimate technologies for further applications in collaborative remote engineering and lab work. This paper presents our latest research to facilitate collaborative experimentation with such innovative technologies. Our vision is a collaborative learning space, which involves an amalgam of real, virtual and remote lab tools to support a wide spectrum of simple and complex, concrete and abstract, safe and dangerous experimentation settings. We will review related concepts and discuss lessons learned from our research and prototype development. Recent work involves the use of mixed reality (as opposed to â??pureâ?? virtual reality) techniques to support seamless collaborative work between remote sites. We describe this and identify areas for future research.

Tele-Lab IT-Security: an Architecture for an online virtual IT Security Lab
Authors: Willems Christian , Meinel Christoph
Published: July 2024

Recently, Awareness Creation in terms of IT
security has become a big thing â?? not only for enterprises.
Campaigns for pupils try to highlight the importance of IT
security even in the userâ??s early years. Common practices in
security education â?? as seen in computer science courses at
universities â?? mainly consist of literature and lecturing. In
the best case, the teaching facility offers practical courses in
a dedicated isolated computer lab. Additionally, there are
some more or less interactive e-learning applications
around.
Most existing offers can do nothing more than impart
theoretical knowledge or basic information. They all lack of
possibilities to provide practical experience with security
software or even hacker tools in a realistic environment. The
only exceptions are the expensive and hard-to-maintain
dedicated computer security labs. Those can only be
provided by very few organizations.
Tele-Lab IT-Security was designed to offer hands-on
experience exercises in IT security without the need of
additional hardware or maintenance expenses. The existing
implementation of Tele-Lab even provides access to the
learning environment over the Internet â?? and thus can be
used anytime and anywhere. The present paper describes
the extended architecture on which the current version of
the Tele-Lab server is built.

Published: July 2024

Nowadays there is a great number of universities and organizations working in e-learning and i-learning solutions. One of the most well-known is the learning management system or LMS that allows displaying theoretical content in an organized and controlled way. In some jobs and studies it is necessary for the student to get a practical knowledge as well as a theoretical one. To obtain this practical knowledge, the universities and organizations are developing Virtual, Remote and Web labs.
At these moments the LMS and Web labs are working independently. We are studying a new architecture allowing the integration of the LMS with different Web labs. This architecture must allow the students, teachers and administrators to use the services of LMS and virtual labâ??s features as if they were working with the same software.
La conversion spirituelle du pétrarquisme dans l’Italie du XVIe siècle : à propos des sonnets spirituels de Vittoria Colonna (1546) et Laura Battiferri (1564)
Authors: Fliege Daniel
Published: July 2024

Vittoria Colonna est la première poétesse à utiliser le pétrarquisme pour traiter de sujets exclusivement spirituels. Ses Rime spirituali, imprimés en 1546, ont connu un grand succès sur le marché du livre. Par conséquent, Vittoria Colonna a également servi de modèle à des poètes ultérieurs tels que Laura Battiferri, qui a publié ses Sonetti spirituali en 1564. Cette contribution montre comment Vittoria Colonna et Laura Battiferri reprennent des éléments du pétrarquisme et les réinterprètent en termes chrétiens. Ce faisant, l’article fait ressortir dans quelle mesure Vittoria Colonna, en particulier, se démarque des recommandations de Pietro Bembo avec ses poèmes religieux, tels que ce dernier les formule dans ses Prose della volgar lingua et ses Rime. L’analyse se concentre sur quatre sonnets, les deux poèmes introductifs des Rime spirituali de Vittoria Colonna et deux sonnets de Laura Battiferri, dans lesquels le motif pétrarquien central du mythe d’Apollon et Daphné est réinterprété en termes chrétiens. On peut montrer que les deux écrivaines font du Christ le nouveau dieu de la poésie, remplaçant le païen Apollon. La réinterprétation de la figure de Daphné-Laure devient plus compliquée et est conservée, chez Colonna, comme un simple jeu de mots avec le terme « vent » (« l’aura »), chez Battiferri elle est réinterprétée négativement comme l’alter ego de la poétesse qui est transformée par le péché en un tronc dur.
Pétrarque entre Poetique et poésie (XVIe-XVIIe siècles). Bembo vs Aristote et la solution baroque en Italie
Authors: Perrone Antonio
Published: July 2024

Cet article embrasse deux siècles de pétrarquisme dans la poésie lyrique italienne. Il entend montrer comment le canon linguistique et littéraire élaboré par Bembo s’est imposé à travers une opération théorique longue et complexe, qui cristallise au tournant des xvie et xviie siècles. Prenant appui sur les interprétations majeures de la Poétique d’Aristote et sur les poètes pétrarquistes les plus représentatifs de la Renaissance et de la période baroque, notre contribution propose une brève histoire de la naissance de la poésie lyrique. Elle insistera tout particulièrement sur le Sud de l’Italie, où le pétrarquisme a ses racines les plus fortes.
La représentation de Londres chez Peter Ackroyd : l’origine comme parcours des possibles
Authors: Cartier Sophie
Published: July 2024

L’œuvre de Peter Ackroyd est une œuvre nostalgique en quête de l’origine d’une anglicité dont l’auteur fouille principalement la mémoire textuelle, parcourant ainsi le corpus de l’héritage littéraire anglais. La dimension spatiale du terme de « parcours » prend toute son importance chez Ackroyd qui ancre la quasi-totalité de son œuvre à l’intérieur de l’espace londonien. Londres s’impose comme l’habitat de la mémoire, comme le lieu où le temps bascule dans l’espace. Londres apparaît par conséquent comme un espace intertextuel vaste et labyrinthique dans lequel les personnages errent et se perdent, leurs itinéraires aléatoires révélant la difficulté éprouvée par l’auteur à fournir une représentation exhaustive du canon littéraire anglais. L’analogie établie entre la forme de l’œuvre et celle de la ville révèle une esthétique de l’excès qui condamne peu à peu les personnages à l’immobilité. Face à cette faillite du schéma et pour que le voyage vers l’origine puisse reprendre, Ackroyd choisira d’effectuer un détour par la fragmentation de la ville, chaque morceau entretenant une relation synecdoquique avec l’ensemble de l’espace urbain, et donc de la tradition. L’œuvre se change dès lors en un système répétitif qui, en même temps qu’il met en valeur la multiplicité des origines de cette tradition littéraire, permet à l’auteur de trouver sa propre voie/voix.
Revisiting Beatrix: Intertextuality, Tradition and Modernity in Evelyn Waugh’s Brideshead Revisited
Authors: Ferrand Aude
Published: July 2024

Evelyn Waugh was a staunch supporter of traditional values, in a world which, according to him, was going down the wrong track—that of modernism. Brideshead Revisited can thus be (re-)placed in Western tradition but its modern dimension needs also to be underlined. The starting point of the present paper is the underlying link between the novel and the painting Beata Beatrix, by Dante Gabriel Rossetti, which eventually brings the reader back to Dante Alighieri and the Bible. To what extent do the several intertextual references, more or less explicit in the novel, plunge the reader into a chamber of echoes? What meaning do they convey?
Quand Salman cherche à faire mauvais genre : analyse des genres dans Fury, de Salman Rushdie
Authors: Miquel Catherine
Published: July 2024

Cet article utilise le terme « genre » dans son acception française de « forme littéraire codée », mais également dans son acception anglaise de gender, pour proposer une analyse du dernier roman en date de Salman Rushdie, Fury. La critique l’ayant accueilli plutôt fraîchement, l’analyse est aussi comparative, établissant des contrastes et des parallèles avec les autres œuvres qui composent ce qu’on peut d’ores et déjà appeler le « canon rushdien ». Rushdie utilise ici différents genres littéraires, qu’ils soient nobles (satire, essai, autobiographie) ou « populaires » (roman noir, journaux à sensation), et cet article problématise la co-existence des deux catégories (« the highbrow and the dross ») au sein d’une œuvre qui se veut « littéraire ». Il examine aussi l’impact d’une focalisation masculine presque unique sur la représentation des personnages féminins dans le roman.
À quoi servent les évaluations institutionnelles ?
Authors: Plane Sylvie , Brissaud Catherine
Published: July 2024

Après avoir évoqué les liens entre didactique du français et évaluation laissée à l’initiative des enseignants, cet article examine le rôle que l’on fait jouer aux évaluations institutionnelles, en particulier en francophonie. Les trois fonctions, certificative, sélective et informative de ces évaluations décidées par l’institution, fonctions parfois intriquées, sont rappelées. Elles sont ensuite détaillées en montrant, nombreux exemples à l’appui, comment on peut s’interroger sur leur évolution, parfois mouvementée, et sur ce qu’elles dévoilent du système éducatif et de son rapport au politique.
La question de grammaire dans les concours de recrutement des enseignants de lettres en France : impacts et dégâts sur la formation
Authors: Atallah Caroline , Camussi-Ni Marie-Armelle
Published: July 2024

Cet article interroge les impacts de la question de grammaire des concours de recrutement en France sur la formation initiale des enseignants de français. S’appuyant sur l’analyse des rapports de jury, il constate le décalage entre les attentes des concours et les préconisations des chercheurs en didactique de la langue, tant sur le plan du contenu que sur le modèle véhiculé. Une enquête menée sur les licences de lettres des universités françaises révèle que celles-ci ne compensent pas ces défauts, en particulier parce que la linguistique peine à y trouver une place, qu’elle soit réelle ou symbolique.
La production de textes dans les évaluations nationales françaises : constats et controverses
Authors: Similowski Kathy
Published: July 2024

L’écriture de texte est une compétence première dans la maitrise du français et les programmes de l’école primaire en France insistent sur la variété des écrits à produire dans toutes les disciplines. Cependant, les dernières évaluations nationales ne comportent plus d’épreuve d’écriture de texte. Ce constat est de nature à nous interpeler. Cet article analyse les évaluations diagnostiques de CE2 et de 6e (8-10 ans) de 1989 à 2007. Quelles compétences y sont évaluées ? Quelle est la pertinence de ces évaluations au regard des résultats de la recherche ? Quel regard l’institution pose-t-elle finalement sur cette compétence fondamentale ? Nous montrons que la production d’écrit est une compétence fondamentale difficilement située, diversement évaluée et qui semble finalement peu valorisée.
Évaluation de la fluence en lecture : au-delà du nombre de mots correctement lus par minute
Authors: Godde Erika
Published: July 2024

Du CP à la 4e, les évaluations nationales utilisent le nombre de mots correctement lus en une minute (NMCLM) pour évaluer la fluence. L’utilisation de cette mesure n’est pourtant pas en adéquation avec la définition de la fluence, qui inclut précision et vitesse, mais aussi phrasé et expression adaptés au texte, dans un but de compréhension. Nous proposons ici d’aligner l’évaluation de la fluence sur sa définition : ne plus se limiter au NMCLM, mais élargir à des tests ciblant toutes les dimensions de la fluence pour la compréhension.
Le test national de compréhension d’un texte littéraire écrit à l’entrée en sixième peut-il constituer un outil pour l’apprentissage ?
Authors: Mercier-Brunel Yann
Published: July 2024

Si les tests nationaux ont pris une place désormais importante dans le paysage éducatif mondial, la France a mis en place des évaluations nationales à plusieurs niveaux d’enseignement. Les objectifs annoncés sont globalement : le pilotage du système éducatif à partir de données fiables et le soutien aux enseignants pour identifier les difficultés de leurs élèves. Notre article propose d’analyser, à partir de travaux scientifiques sur l’évaluation de l’apprentissage, les exercices de compréhension d’un texte littéraire écrit du test national standardisé de 2022 proposé en début d’année en classe de 6e, afin d’étudier si, comme les auteurs du test l’annoncent, ces exercices sont en mesure d’apporter des informations utiles aux enseignants pour concevoir des actions pédagogiques précises.
Les technologies médiatiques dans le traitement de la crise de Grand-Bassam en Côte d’Ivoire
Authors: Agnini Toa Jules Evariste
Published: July 2024

Les technologies médiatiques, dans cette réflexion, sont comprises comme l’ensemble de l’arsenal innovant des moyens et des outils de communication, en dehors des médias traditionnels. Cette étude, sous l’angle de la théorie des représentations et dans le cadre épistémologique de la socio- anthropologie, analyse l’impact de ces technologies dans le traitement de la crise survenue le 13 mars 2016 à Grand-Bassam, suite à l’attaque criminelle des assaillants djihadistes. En effet, grâce aux TIC et leurs multiples applications, la production en grande série d’informations sur la crise a été diffusée à travers les réseaux sociaux. Ce qui dénote leur impact réel qui a, d’ailleurs, contraint le gouvernement ivoirien à mener une communication de crise lors des événements de Grand-Bassam.
By a Thread: Encoding Online Forum Data in TEI
Authors: Reimann Sebastian , Rodenhausen Lina , Elwert Frederik , Scheffler Tatjana
Published: July 2024

Online forums are platforms where users interact in conversations organized around common topics. In this paper, we make a proposal for encoding forum data according to the TEI Guidelines using a unified format, which covers both traditional online forums as well as Reddit, the largest platform that offers forum functionality. We first discuss the specific properties of various types of forums, including most prominently their treelike thread structure. We argue that this tree structure is best represented in a nested XML tree, and does not follow existing stream- or timestamp-based CMC schemas. We present a solution that makes use of a wide range of previously available elements from the TEI Guidelines and the CMC-core schema to encode forums with different thread structures, types of post reactions, and sets of available emojis. Moreover, we propose a TEI header for storing forum metadata within the context of interdisciplinary research, which addresses the challenges of applying TEI elements to born-digital data. Finally, we propose customizations to preexisting TEI elements that are necessary to cover several peculiarities of online forums.
A Comment Aspect-Level User Preference Transfer Model for Cross-Domain Recommendations
Authors: Zhang Wumei , Zhang Jianping , Zhang Yongzhen
Published: July 2024

Traditional cross-domain recommendation models make it difficult to deeply mine users' aspect-level preferences from comment information due to existing problems such as polysemy of comment text, sparse comment data, and user cold start. A Cross-Domain Recommender (CDR) model that integrates comment knowledge enhancement and aspect-level user preference transfer (C-KE-AUT) was proposed to address the above issues. Firstly, an aspect-level user preference extraction model was constructed by combining the RoBERTa word embedding model, high-level feature representation based on Transformer, and aspect-level attention-learning methods. Then, a user aspect-level preference cross-domain transfer model was constructed based on a two-stage generative adversarial network that can transfer the aspect-level interest preferences of users in the source domain to the target domain with sparse data. The experimental results on the Amazon 2018 comment dataset indicated that the recommendation performance of the proposed C-KE-AUT model was significantly superior to other advanced comparative models.

The banana fruit fly (Bactrocera musae Tryon), belonging to the family Tephritidae and subfamily Dacinae, is the main pest of bananas responsible for significant crop losses. In order to monitor the B. musae infestation, we collected banana fruit samples from four locations on the Gazelle Peninsula: Burit, Kereba, Vudal, and Vunapalading. On each field collection date, twelve banana bunches were chosen at random from the corresponding study sites. Following the removal of 100 individual fruits (fingers) from each fresh bunch at each study site, the fruits were weighed, thoroughly cleaned with rainwater three times, and then incubated in containers until the larval developmental stages were finished. When compared to the other three sites, the number of adults in the Kalapua bananas sampled from Burit was the highest. The banana fruits were divided into three main groups: “mature green”, “mature ripe”, and “immature green”. Mature green fruits produced a higher adult abundance than mature ripe fruits. Compared to the other two stages, immature green had the fewest adults. By fruit weight, Burit had the highest infestation (20.9%), while Vunapalading had the lowest (11.9%). After Kereba (14.7%), Vudal had the second-highest infestation (16.8%). Mature ripe fruit had the highest infestation (37.1%) by fruit weight, while immature green fruits had the lowest infestation (2.04%). A moderate level of infestation was observed in mature green fruits (17.1%). Regarding fruit count, the least infected fruits were immature green fruits (1.8%), moderately infected mature green fruits (17.0%), and highly infected mature ripe fruits (26.9%). Geographically, the Gazelle Peninsula has a Kalapua infestation level ranging from 11.9 to 20.9%, and a different maturity stage infestation level ranging from 2.04 to 26.9%. In general, the degree of infestation has escalated, and B. musae has established itself in the Gazelle Peninsula.
