Dermatofibrosarcoma protuberans (DFS) is a rare malignant skin tumor, characterized by local aggressiveness, significant potential for recurrence and a low risk of distant metastasis. The location under the eyes, not yet reported in the literature may involve the functional and aesthetic prognosis. We report a case.

FR. Cet article propose de questionner la capacité des nouveaux entrants de l’information locale à renouveler le processus d’alimentation du débat démocratique dans leur territoire de diffusion, face à une Presse Quotidienne Régionale en situation hégémonique. Nous faisons ainsi l’hypothèse qu’un journalisme local, construit contre ou à côté de l’acteur hégémonique, serait en mesure de catalyser les transformations à l’œuvre dans le champ journalistique en défendant l’introduction de voix dissidentes (Benson & Neveu, 2005 ; Smyrnaios & Thiong-Kay, 2023) dans des territoires jusqu’ici marqués par la construction médiatique du consensus. À partir de la conception « multiréférentielle » du territoire avancée par Boure et Lefebvre (2000), nous envisageons en effet celui-ci comme structuré par l’opposition entre, d’un côté, l’exercice d’un pouvoir institutionnel et la cristallisation d’un temps social partagé et, de l’autre, des rapports sociaux dissymétriques et des mises en sens plurielles ou concurrentes. Au final, c’est donc le « travail territorial » des médias (Noyer & Raoul 2011) que nous avons cherché à appréhender. Notre étude a porté sur 11 médias situés en région Auvergne Rhône-Alpes et comportant dans leur rédaction au moins un journaliste professionnel. Par le biais d’entretiens semi-directifs, complétés d’une attention au méta-discours des médias, nous envisageons leur rapport au territoire dans une triple dimension (marché, terrain et espace public local). Nos résultats confirment d’abord, chez les acteurs étudiés, une dynamique structurante de professionnalisation précédemment observée dans les médias alternatifs (Ferron 2006). Mais ils révèlent également une forme de polarisation entre deux idéaux-types journalistiques, que nous caractérisons à la lumière des travaux de Nielsen (2015). En effet, si certains médias ambitionnent de réduire les disparités d’accès à la connaissance des affaires publiques parmi les citoyens (réduction du « knowledge gap »), d’autres semblent avant tout attachés à susciter l’engagement civique et politique des citoyens dans l’espace local (réduction de l’« engagement gap »). *** EN. This article examines the ability of the new players of local news to renew the process of democratic debate in their zone of distribution, in the face of hegemonic regional daily press. We thus hypothesize that local journalism, built in opposition to or alongside dominant players, could catalyze the transformations at work in the journalistic field by championing the introduction of dissenting voices (Benson & Neveu, 2005; Smyrnaios & Thiong-Kay, 2023) in territories characterized until now by the media’s construction of consensus. Based on the "multi-referential" conception of territory put forward by Boure and Lefebvre (2000), we consider it to be structured by the opposition between, on the one hand, the exercise of institutional power and the crystallization of collective social time and, on the other, asymmetrical social relationships and plural or competing enactments of meaning. Ultimately, our aim was to understand the "territorial work" of the media (Noyer & Raoul 2011). Our study focused on 11 media located in the Auvergne Rhône-Alpes region, each of which had at least one professional journalist on its editorial staff. Through semi-structured interviews, combined with a focus on the media's meta-discourse, we examined the media's relationship with its territory from three perspectives (market, field and local public space). Our results confirm, among the actors studied, the structuring dynamics of professionalization previously observed in alternative media (Ferron 2006). They also reveal a form of polarization between two journalistic ideal-types, which we characterize in the light of Nielsen's work (2015). Indeed, while some media aim to reduce disparities in access to knowledge of public affairs among citizens (reduction of the "knowledge gap"), others seem above all committed to fostering civic and political engagement among citizens in the local space (reduction of the "engagement gap"). *** PT. O objeto deste artigo é discutir como os novos atores do noticiário local podem renovar o processo de documentação do debate democrático em suas áreas de transmissão, frente à posição hegemônica da Imprensa Diária Regional. Levanta-se a hipótese de que um jornalismo local, construído contra ou ao lado do ator hegemônico, seja capaz de catalisar as transformações em curso no campo jornalístico ao defender a introdução de vozes dissidentes (Benson & Neveu, 2005; Smyrnaios & Thiong-Kay, 2023) em territórios até então marcados pela construção midiática do consenso. De fato, com base na concepção “multirreferencial” do território apresentada por Boure e Lefebvre (2000), considera-se que o território é estruturado pela oposição entre, de um lado, o exercício do poder institucional e a cristalização de um tempo social compartilhado e, de outro, as relações sociais assimétricas e as atribuições de sentidos plurais ou concorrentes. Dessa forma, em última análise, o que procuramos compreender é o “trabalho territorial” da mídia (Noyer & Raoul 2011). O estudo considerou 11 meios de comunicação localizados na região de Auvergne Rhône-Alpes, com pelo menos um jornalista profissional em sua equipe editorial. Por meio de entrevistas semiestruturadas, complementadas por um foco no metadiscurso da mídia, analisou-se a relação desses veículos com o território sob uma tripla perspectiva (de mercado, em campo e no espaço público local). Os resultados confirmam, em primeiro lugar, que há, entre os atores estudados, a mesma dinâmica estruturante de profissionalização já observada na mídia alternativa (Ferron, 2006). Mas evidencia-se também uma forma de polarização entre dois tipos de ideais jornalísticos, caracterizados aqui à luz do trabalho de Nielsen (2015). Com efeito, enquanto alguns meios de comunicação objetivam reduzir as disparidades no acesso ao conhecimento dos assuntos públicos entre os cidadãos (redução do “knowledge gap”), outros parecem estar comprometidos principalmente com a promoção do engajamento cívico e político dos cidadãos no espaço local (redução do “engagement gap”). *** ES.

Le renouvellement de nombreuses essences d’intérêts économique et écologique est remis en cause par une hausse généralisée des populations de cervidés et des dégâts qu'ils occasionnent. La simulation d’abroutissement est une méthode expérimentale consistant à combiner la section mécanique de la plante et l’application de salive de cervidés sur la zone sectionnée qui permet de contrôler précisément les épisodes d'abroutissement auxquels sont soumis les plants. Nous illustrons ici, par deux exemples, les possibilités offertes par cette technique pour comprendre les effets des abroutissements de chevreuil sur la croissance et survie des plants de Chêne. Messages clés • La simulation d’abroutissement consiste à imiter l’herbivorie en combinant section mécanique et application de salive sur la plante. • L’abroutissement simulé réduit de 50 % la survie des semis de Chêne. • Les semis répondent en investissant dans les traits fonctionnels favorisant la croissance (teneur foliaire en azote et chlorophylle).

On its website, Sciences du jeu describes itself as an “international and interdisciplinary journal whose mission is to develop and promote French-speaking researc[h] on play”, “to foster dialogue between social sciences and set off debates on this particular subject”. Created in 2013 following a study day in tribute to the work of Jacques Henriot, its scientific program clearly follows in his footsteps. Indeed, Sciences du jeu defines itself not only as “open to all approaches or methods”, but also to “every aspect of play” (including, but not exclusively, video games) and to "researc[h] from various fields related to play in a broad sense (objects, structures, situations, experiences, attitudes)”. Ten years after the publication of the first issue of the journal, we may well ask to what extent the articles published to date reflect the original approach of play originally promoted by Henriot. What about the references to this author and to the concepts he developed in his work? More generally, what are the bibliographical references most frequently used by the journal’s authors? What do they tell us about their conception of play and how they approach it? On which disciplinary approaches and methods are their analyses most often based? What types of games, themes and/or fields are most frequently studied? What are the gray areas and less visible fields? Finally, who are the authors of these papers (in terms of gender and status), where do they come from (in terms of affiliation and disciplinary roots) and how does this influence their perspective on play? To answer these questions, this paper draws on a bibliometric, lexicometric and sociological analysis based on a corpus comprising all the articles published in the first seventeen issues of the journal.

Les prairies et pâturages représentent 25 % des terres émergées. Une exploitation efficiente et durable de ces ressources fourragères nécessite notamment une gestion adaptée des plantes envahissantes très souvent responsables de leur dégradation. Cette gestion nécessite de disposer de connaissances sur leur comportement et pour cela une bonne identification. Le portail collaboratif Wiktrop aide à identifier les adventices et facilite le partage et la diffusion des connaissances sur les adventices tropicales et leur gestion entre acteurs de terrain et scientifiques. Ces connaissances permettent d’améliorer les pratiques de contrôle des adventices dans l’ensemble des régions tropicales et méditerranéennes. La contribution des utilisateurs est un facteur important de la qualité et de l’étendue des informations mises à disposition. Ce portail évoluera prochainement avec l’intégration des plantes fourragères et des plantes de services tropicales.

This article aims to contribute to reflections on what makes occupational risk prevention sustainable, based on the analysis of the work of prevention advisors. It is rooted in a research-intervention commissioned by the Caisse Centrale de la Mutualité Sociale Agricole (MSA), as part of its 2021-2025 Occupational Health and Safety Plan. Firstly, the theoretical framework articulates three fields of the ergonomics literature: 1) the literature on sustainable prevention of MSDs, 2) the literature on the notions of sustainable work and decent work, and 3) the literature on the concept of sustainable development; together, this enables to identify an original reading grid to characterize sustainable prevention. Secondly, based on a retrospective analysis of six service relationships conducted by prevention advisors from four MSA with affiliated companies, we show that the quality of the service relationship is a condition for the sustainability of prevention. The prevention advisors aim to build unique and lasting relationships with their members. These relationships are a means of co-constructing actions that promote collective and primary prevention. Each prevention action is thus thought of as a part in a potential larger game that may (or may not) be actualized. These results are discussed along four axes in the light of the three fields of literature mentioned.

The work presented in this paper is to tend towards a goal of developing a methodology and associated software module to establish cross-correlation between real time process monitoring data and characterization data. To implement this methodology, a number of steel specimen were built following a design of experiment approach. During the manufacturing, all monitoring data was recorded in log files with a precise timestamp, the data collected being then temporal signals. Subsequently, these parts were inspected by high resolution X-ray tomography, and the defects present in the part were characterized, resulting in 3D volumetric dataset. The software module developed on CIVA platform then enables the registration of these multi-physics data.

The site of Lalibela is the result of Tertiary volcanic activity which led to the formation of a vast outcrop of basaltic slag from which churches were carved. This reddish rock which is particularly suitable for carving, is extremely interactive with water. It was beneficial for the impressive excavation phases, but is now problematic for conservation purposes. Digging meant either the penetration of water into the massif and its erosion, but also the protection of the monuments from water stagnation. This is a very paradoxical situation in which water plays an alternately positive and negative role. Due to its sacred dimension, any intervention on the rock must be discussed and validated by the community. 3D technologies were used to carry out an assessment of the state of the site, to create a virtual 3D model that can be accessed and consulted remotely by all the specialists faced to the conservation problem; to trace the historical evolution of the site.

Recent publications by poet and artist Caroline Bergvall shift the old paradigm of both the poetry collection and the book-poem. This shift can be analyzed with the notion of “remix” that Lev Manovich uses to characterize new media. Bergvall’s recent books (Meddle English and Drift) are remixes in terms of their structure, of their individual texts, but above all in terms of their remediation as podcasts, performances, shows, printed material. They anticipate the “remixability” of her most recent projects subsumed under the title Sonic Atlas. But Bergvall’s remixability is not formal or technological, it is a poetics and a politics of multiplicity that seeks to define how to live together now.

Le système d’élevage pastoral est critiqué pour son impact environnemental en raison des fortes émissions de gaz à effet de serre par unité de produit et l’effet néfaste sur le sol et la végétation. Au Sénégal, le stock de carbone dans la végétation est suivi par le Centre de suivi écologique dans 24 sites du Sahel depuis 1987. Toutefois, le stock de C du sol, paramètre essentiel aux processus d’humification de la litière des arbres et de rhizodéposition des herbacées, n’est pas pris en compte. Cette étude visait à déterminer l’influence de l’arbre et des facteurs environnementaux sur les teneurs en C du sol. Ainsi, 15 sites de suivi du Centre ont été sélectionnés, et 480 échantillons de sol ont été prélevés à 0–10 cm et 10–30 cm de profondeur sous et hors houppier. Les teneurs en C et en N totales ont été prédites par spectroscopie proche infrarouge (SPIR) et les stocks de C et de N calculés à partir de 60 échantillons de sol prélevés sous et hors houppier. Une analyse en composantes principales a permis d’identifier les facteurs impliqués dans la variation des stocks de C. Ainsi, dans la zone sylvopastorale du Sénégal, ces stocks ont varié le long d’un gradient nord-sud ; ils ont été positivement corrélés à la pluviométrie, au taux de couverture arborée et à la biomasse. Ils ont varié entre 9,3 et 29,7 Mg C/ha à 10–30 cm. A une échelle plus fine, l’arbre a induit une augmentation des teneurs en C et en N sous houppier dans l’horizon 0–10 cm. Cette étude a montré que les stocks de C du sol peuvent servir à déterminer les besoins de compensation des émissions de C dans le Sahel à travers la plantation d’arbres.

Description of the subject. Phenolic compounds are very important to the antioxidant capacity of plant species. Phenolic compounds and hence antioxidant capacity are commonly measured in the laboratory using indirect methods that involve several stages and chemicals. Objectives. This study aims to identify species with high content of phenolic compounds and antioxidant capacity and to measure these parameters in the leaves of fruit species using near-infrared spectroscopy (NIRS). Method. A total of 68 samples of different varieties of Prunus avium, Prunus cerasus, Malus domestica, Prunus domestica, Pyrus communis, Vitis vinifera, Ficus carica and Corylus avellana were investigated. The dried ground leaves were scanned in reflectance mode and the phenolic compound content (total phenolic compounds, total flavanols and total flavonols) and antioxidant capacity (2-2-diphenyl-1-picrylhydazil [DPPH] and oxygen radical absorbance capacity [ORAC]) were determined. Results. Great variability of phenolic compound content and antioxidant capacity was observed between species (inter-species) and between varieties (intra-species). The spectra with and without pre-treatments were tested to correlate with the phenolic compound content and antioxidant capacities. The pre-treatments tested showed a slight improvement in statistical parameters (R²CAL > 0.75; R²CV > 0.21; RPD > 1.1). Conclusions. The results suggest that NIR spectroscopy with chemometric approaches could be used to rapidly estimate the phenolic compound content and antioxidant capacity of the leaves of fruit species. The species evaluated in this study were shown to be a rich source of phenolic compounds and antioxidants.

Description of the subject. Given the current low price of milk, a lot of producers have decided to process their milk into products with a higher added-value, including butter. However, all milks are not suitable to be transformed into butter. It would thus be useful to be able to predict milk processing properties. Objectives. The aim of this paper was to study the ability of milk to be processed into butter using infrared spectrophotometry. Method. A normalized protocol for the production of butter was developed. Milk samples (n = 110) collected between 2013 and 2016 were analyzed by near and medium infrared spectrometry (315 spectra). Butter samples were also analyzed by visible-near infrared spectrometry (220 spectra). Composition of the products was subsequently assessed using validated prediction equations. Principal components analyses were performed to discriminate samples. Results. Butter properties seemed to be influenced by seasons and feedings. Water content and color parameters could be predicted on the basis of butter infrared spectra. Conclusions. It was possible to correlate butter characteristics with milk properties. However, it was not possible to predict butter characteristics on the basis of milk near infrared spectra. It could be interesting to try predictions from milk medium infrared spectra.

Civilization VI Gathering Storm offers important new features, including the effects of fossil fuel consumption on CO2 emissions, the climate changes and the occurrence of natural disasters. The game analysis shows the importance of different types of disasters in a game. The management of disaster risks simulated in the game is carried out according to a technicist perspective since many technologies discovered over the course of a game make it possible to manage disaster risks and maintain the expansion and ownership of the territory. The probability of occurrence and the intensity of certain disasters will also increase with global warming linked to the increase in CO2 emissions from the industrial age. The management of these climate changes can be achieved thanks to the World Congress allowing a temporary ban on the exploitation of certain resources. In general, the game simulates some current environmental issues, but does not completely render a model of sustainable development, because the proposed political and technological solutions rule out the social and ecological impacts of these choices and do not integrate many contemporary environmental issues. These principles of the game can be questionable. However, from a didactic point of view, they can also constitute learning opportunities because the game offers an important playful aspect and offers real freedom of choice of the type of development. The game thus has didactic and educational potential by allowing students to discuss a vision of sustainable development based solely on political and technological control.

Excavations carried out between 2012 and 2013 atWakarida in northeastern Tigray uncovered a huge quantity ofpottery distributed across the different levels identified at thesite. The different pottery assemblages collected from the siteare presented in this contribution, proposing a periodizationof the occupation of Wakarida city into two main units: PeriodI (subdivided into successive phases IA and IB) and Period II.Pottery comparisons and 14C dating provide the grounds fordating the two assemblages.

Although Brazil is among the world's largest consumers of pesticides, their impacts on local populations have struggled to emerge as a public problem due to a political context that is particularly favourable to industrial agriculture. In this article, we investigate how the knowledge produced on the impact of pesticides contributes (or not) to the emergence of this public problem. We conduct a reflection based on a citizen science process we conducted in the region of Santarem, in the Brazilian Amazon, where soybean has been expanding significantly for the past 20 years. Since 2017, we have built an observatory in partnership with peasant unions to make visible the impact of pesticides used in soy crops on family farmers. Young farmers, trained to become "community researchers", have administered 544 questionnaires to family farmers to learn about their practices and assess the changes caused since the arrival of soy. We conduct an analysis at three levels: at the national level, we follow the emergence of pesticides as a public issue, its consolidation during the Labor government (2003-2016), and then its dismantling; at a local level, the survey reveals how the family farmers are impacted by soy pesticides and at the same time, not so aware of being "victims"; finally, at the territorial level, we question the weakening of the debate between science and politics, particularly within the Regional Forum for the fight against the impact of pesticides set up in Santarém.

• We need to understand how future teachers make sense of theory and practice during a didactics course and a practicum field experience. • Different assignments can show us how future teachers think about history teaching and teaching practices. • Theoretical links are superficial and relate to the nature of assignment even though future teachers demonstrate a progression in their view of teaching practices • We need to ensure greater coordination between partner schools • Different assignments foster different modes of reflection on practice and we must encourage this variety. Purpose: This article presents a case study exploring how future teachers combine scientific knowledge and practical knowledge during a history didactics course and practicum field experience in history teaching in Quebec high schools. Design: Through a thematic analysis of the written assignments submitted during the practicum and conceptual maps designed as part of the didactics course, links between theory and practice are highlighted. Results: Future teachers’ referring to different types of knowledge depends on the expectations specified for each written assignment, and shows discourse with little critical distance. However, the concept maps show a more complex representation of teaching practices which can be explained by both the didactics course and the experiential and practical knowledge gained through the practicum. Implications: This composite of experiences puts initial teacher training into perspective along a continuum that requires consolidating university expectations and varying school practices. Closer collaboration is needed between the different actors involved in both theoretical courses and practical training.
