SDSS J0018-0939: A Clear Signature of Sub-Chandrasekhar Mass Type 1a Supernova
Authors: Jeena S. K. , Banerjee Projjwal
Published: October 2024

Very metal-poor (VMP) stars ([Fe/H] ≤ −2) that have subsolar values of [X/Fe] for α elements such as Mg, Si, and Ca, are referred to as α-poor VMP stars. They are quite rare among VMP stars and are thought to have formed from gas enriched predominantly by a single Type Ia supernova (SN 1a) in contrast to most VMP stars, which are α-enhanced and usually associated with core-collapse supernovae. The observed abundance pattern in such stars can provide a direct way to probe the nucleosynthesis in individual SN 1a. Although the abundance patterns in some α-poor VMP stars have been shown to be consistent with SN 1a ejecta, a clear nucleosynthetic signature for SN 1a resulting from the explosion of a near Chandrasekhar mass (near-M
Ch) or a sub-Chandrasekhar mass (sub-M
Ch) white dwarf, has not been unambiguously detected. We perform a detailed analysis of various formation channels of VMP stars and find that the α-poor VMP star SDSS J0018-0939, which was earlier reported as a star with potential pair-instability supernova origin, provides a near-smoking-gun signature of a sub-M
Ch SN 1a resulting from He detonation. We find that compared to other α-poor VMP stars that were previously identified with SN 1a, SDSS J0018-0939 is the only star that has a clear and unambiguous signature of SN 1a. Interestingly, our results are consistent with constraints on SN1 a from recent galactic chemical evolution studies that indicate that sub-M
Ch SN 1a accounts for ∼50%–75% of all SN 1a and is possibly the dominant channel in the early Galaxy.
From Coasting to Energy-conserving: New Self-similar Solutions to the Interaction Phase of Strong Explosions
Authors: Coughlin Eric R.
Published: October 2024

Astrophysical explosions that contain dense and ram-pressure-dominated ejecta evolve through an interaction phase, during which a forward shock (FS), contact discontinuity (CD), and reverse shock (RS) form and expand with time. We describe new self-similar solutions that apply to this phase and are most accurate in the limit that the ejecta density is large compared to the ambient density. These solutions predict that the FS, CD, and RS expand at different rates in time and not as single temporal power laws, are valid for explosions driven by steady winds and homologously expanding ejecta, and exist when the ambient density profile is a power law with a power-law index shallower than ∼3 (specifically when the FS does not accelerate). We find excellent agreement between the predictions of these solutions and hydrodynamical simulations, both for the temporal behavior of the discontinuities and for the variation of the fluid quantities. The self-similar solutions are applicable to a wide range of astrophysical phenomena and—although the details are described in future work—can be generalized to incorporate relativistic speeds with arbitrary Lorentz factors. We suggest that these solutions accurately interpolate between the initial “coasting” phase of the explosion and the later, energy-conserving phase (or, if the ejecta is homologous and the density profile is sufficiently steep, the self-similar phase described in R. A. Chevalier).
Robust Support for Semi-automated Reductions of Keck/NIRSPEC Data Using PypeIt
Authors: Carvalho Adolfo S. , Doppmann Greg , Westfall Kyle B. , Pelliccia Debora , Prochaska J. Xavier , Hennawi Joseph , Davies Frederick B. , Brodheim Max , Wang Feige , Cooke Ryan
Published: October 2024

We present a data reduction pipeline (DRP) for Keck/Near InfraRed SPECtrograph (NIRSPEC) built as an addition to the PypeIt Python package. The DRP is capable of reducing multi-order echelle data taken both before and after the detector upgrade in 2018. As part of developing the pipeline, we implemented major improvements to the capabilities of the PypeIt package, including manual wavelength calibration for multi-order data and new output product that returns a coadded spectrum order-by-order. We also provide a procedure for correcting telluric absorption in NIRSPEC data by using the spectra of telluric standard stars taken near the time of the science spectra. At high resolutions, this is often more accurate than modeling-based approaches.
Canagliflozin exerts anti-inflammatory and antioxidant effects in the heart and skin tissues: Biochemical and histopathological assessment in a model of accelerated aging induced by D-galactose in mice
Authors: Mahmood Ahmed Mohammed , Kassid Ahmed Ageeb , Al-Zuaini Hashim H. , Abd-Alhussain Ghasak Kais
Published: October 2024

Canagliflozin was assessed for its anti-inflammatory and antioxidant effects as an anti-aging drug in animal models. 50 Swiss albino male mice were divided into five groups; all groups received their intervention using gastric gavage; group 1 received normal saline for 14 weeks; group 2 received induction by D-galactose 200 mg/kg/day for seven weeks; and group 3 to 5 received the same induction for seven weeks, followed by another seven weeks of investigated drugs; group 3 received Vitamin C (100 mg/kg/day); group 4 received canagliflozin (3 mg/kg/day); and group 5 received canagliflozin (1 mg/kg/day). At the end of 14 weeks, all animals were euthanasiad, and heart and skin tissue were harvested for further analysis. Canagliflozin at both 1 and 3 mg/kg was successful in reducing the levels of inflammatory mediators (TNF-alpha and IL6), reducing levels of MDA, increasing the levels of SOD, and increasing the levels of collagen-1 and elastin in skin tissue. Additionally, 3 mg/kg Canagliflozin showed a better effect compared to 1 mg/kg regarding its effect on IL6, SOD, and elastin. Histopathologically, treatment with both doses of Canagliflozin attenuates abnormalities induced by D-galactose (bizarre, irregular, and hyperchromatic nuclei). Canagliflozin exhibits potent antioxidant and anti-inflammatory effects in living organisms, effectively prevents cardiac and skin damage generated by D-galactose, and possibly reduces aging.

Published: October 2024

Weevils represent one of the most speciose and economically important animal clades, but remain poorly studied across much of the Oriental Region. Here, an integrative revision of the Oriental, flightless genus Aphanerostethus Voss, 1957 (Curculionidae: Molytinae) based on X-ray microtomography, multi-gene DNA barcoding (CO1, Cytb, 16S), and traditional morphological techniques (light microscopy, dissections) is presented. Twelve new species, namely, A. armatus Lewis & Kojima, sp. nov., A. bifidus Kojima & Lewis, sp. nov., A. darlingi Lewis, sp. nov., A. decoratus Lewis & Kojima, sp. nov., A. falcatus Kojima, Lewis & Fujisawa, sp. nov., A. incurvatus Kojima & Lewis, sp. nov., A. japonicus Lewis & Kojima, sp. nov., A. magnus Lewis & Kojima, sp. nov., A. morimotoi Kojima & Lewis, sp. nov., A. nudus Lewis & Kojima, sp. nov., A. spinosus Lewis & Kojima, sp. nov., and A. taiwanus Lewis, Fujisawa & Kojima, sp. nov. are described from Japan, Taiwan, Vietnam, and Malaysia. A neotype is designated for A. vannideki Voss, 1957. The hitherto monotypic genus Darumazo Morimoto & Miyakawa, 1985, syn. nov. is synonymized under Aphanerostethus based on new morphological data and Aphanerostethus distinctus (Morimoto & Miyakawa, 1985), comb. nov. is transferred accordingly. X-ray microtomography is successfully used to explore for stable interspecific differences in cuticular, internal and micro morphology. Remarkable species-specific sexual dimorphism in the metatibial uncus is described in seven of the newly described Aphanerostethus species and the evolution of this character is discussed.
Predicting the correlation between neurological abnormalities and thyroid dysfunction using artificial neural networks
Authors: Al-Sabak Dina Falah Noori , Sadeghi Leila , Dehghan Gholamreza
Published: October 2024

In this work, a deep learning model was developed to predict future neurological parameters for patients with hypothyroidism, enabling proactive health management. The model features a sequential architecture, comprising a long short-term memory (LSTM) layer, a bidirectional LSTM layer, and several fully connected layers. The study assessed the interplay between serum cortisol, dopamine, and GABA levels in hypothyroid individuals, aiming to illuminate how these hormonal fluctuations influence the condition's symptoms and progression, especially in relation to Parkinson's disease. Conducted at the Tabriz Sadra Institute of Medical Sciences in Iran, the observational study involved 80 hypothyroid patients and 80 age-matched healthy controls. The findings showed a correlation between cortisol levels and TSH and an inverse relationship with T3 and T4 levels among hypothyroid patients. Dopamine levels also correlated with TSH, T3, and T4, highlighting their potential impact on Parkinson's disease. Notably, hypothyroid patients aged 54–71 years old experiencing visual hallucinations had reduced occipital GABA levels correlating with hormone levels. The results indicated significant relationships among cortisol, dopamine, and GABA levels, providing insights into their roles in the pathophysiology of hypothyroidism and its association with neurological disorders. The BiLSTM model achieved the highest accuracy at 92.79% for predicting Parkinson's disease likelihood in adult hypothyroid patients, while the traditional LSTM model reached 84.48%. This research suggests promising avenues for future studies and has important implications for clinical management and treatment strategies.
Analysis of global dynamics in an attraction-repulsion model with nonlinear indirect signal and logistic source
Authors: Wang Chang-Jian , Zhu Jia-Yue
Published: October 2024

The following chemotaxis system has been considered:

   \begin{document}$ \begin{equation*} \left\{ \begin{array}{ll} v_{t} = \Delta v-\xi \nabla\cdot(v \nabla w_{1})+\chi \nabla\cdot(v \nabla w_{2})+\lambda v-\mu v^{\kappa},\ &\ \ x\in \Omega, \ t>0,\\[2.5mm] w_{1t} = \Delta w_{1}-w_{1}+w^{\kappa_{1}}, \ 0 = \Delta w-w+v^{\kappa_{2}}, \ &\ \ x\in \Omega, \ t>0,\\[2.5mm] 0 = \Delta w_{2}-w_{2}+v^{\kappa_{3}}, \ &\ \ x\in \Omega, \ t>0 , \end{array} \right. \end{equation*} $\end{document}

under the boundary conditions of $ \frac{\partial{v}}{\partial{\nu}} = \frac{\partial{w_{1}}}{\partial{\nu}} = \frac{\partial{w}}{\partial{\nu}} = \frac{\partial{w_{2}}}{\partial{\nu}} $ on $ \partial \Omega, $ where $ \Omega $ was a bounded smooth domain of $ \mathbb{R}^{n}(n\geq 1), \; \nu $ was the normal vector of $ \partial\Omega, $ and the parameters were $ \lambda, \mu, \xi, \chi, \kappa_{1}, \; \kappa_{2}, \kappa_{3} > 0, $ and $ \kappa > 1. $ In this paper, we showed that if either $ \kappa_{1}\kappa_{2} < \max\{\frac{2}{n}, \kappa_{3}, \kappa-1\} $ or $ \kappa_{1}\kappa_{2} = \max\{\frac{2}{n}, \kappa_{3}, \kappa-1\} $ with the coefficients and initial data satisfying appropriate conditions, then the system possessed a global classical solution. Furthermore, we also have studied the convergence of solutions to a special case of the above system with $ \kappa = \delta+1, \kappa_{1} = 1, \kappa_{2} = \kappa_{3} = \delta $ for $ \delta > 0. $ It has been proven that if $ \mu > 0 $ is large enough, then the corresponding classical solutions exponentially converged to $ ((\frac{\lambda}{\mu})^{\frac{1}{\delta}}, \frac{\lambda}{\mu}, \frac{\lambda}{\mu}, \frac{\lambda}{\mu}), $ where the convergence rate could be formally expressed by the parameters of the system.
Modeling the role of fish population in mitigating algal bloom
Authors: Sajid Mohammad , Misra Arvind Kumar , Almohaimeed Ahmed S.
Published: October 2024

Algal blooms pose a significant threat to the ecological integrity and biodiversity in aquatic ecosystems. In lakes, enriched with nutrients, these blooms result in overgrowth of periphyton, leading to biological clogging, oxygen depletion, and ultimately a decline in ecosystem's health and water quality. In this article, we presented a mathematical model centered around the role of aquatic species (specifically fish population) to alleviate algal blooms. The model analysis revealed significant shifts in dynamics, shedding light on the effectiveness of fish-mediated sustainability strategies to control algal proliferation. Notably, our study identified critical thresholds and regime transitions through the observation of saddle-node bifurcation within the proposed mathematical model. To validate our analytical findings, we have conducted numerical simulations, which provided robust evidence for the resilience of the ecosystem under different scenarios.
Comparative secretome analysis unveils species-specific virulence factors in Elsinoe perseae, the causative agent of the scab disease of avocado (Persea americana)
Authors: Chellappan Biju Vadakkemukadiyil
Published: October 2024

The scab disease, caused by Elsinoe perseae, poses a significant risk to avocado (Persea americana) production in countries with warm and humid climates. Although the genome has been published, the precise virulence factors accountable for the pathogenicity of E. perseae have not yet been determined. The current study employed an in silico approach to identify and functionally characterize the secretory proteins of E. perseae. A total of 654 potential secretory proteins were identified, of which 190 were classified as carbohydrate-active enzymes (CAZymes), 49 as proteases, and 155 as potential effectors. A comparison to six other closely related species identified 40 species-specific putative effectors in E. perseae, indicating their specific involvement in the pathogenicity of E. perseae on avocado. The data presented in this study might be valuable for further research focused on understanding the molecular mechanisms that contribute to the pathogenicity of E. perseae on avocado.

Políticas del resentimiento. Regresión y desclasamiento en Regreso a Reims de Didier Eribon
Authors: Cano German
Published: October 2024

Para algunos analistas críticos recientes interesados en rehabilitar la categoría de resentimiento, la trampa que invoca la necesidad de un “regreso social” estriba en entender simplificadamente que cierta hipertrofia “culturalista” de las políticas de la identidad erosionó las bases de la clase trabajadora. Un análisis crítico del resentimiento muestra cómo este discurso falsamente “materialista” del “regreso social” ha tenido como objetivo, sobre todo, desagregar y escindir un posible bloque emancipatorio social y cultural desde los marcos de la batalla ideológica. Bajo esta perspectiva, este supuesto “regreso” sirve de coartada ideológica y hegemónica en la estrategia conservadora para separar y autonomizar las luchas. En esta contribución se intenta matizar y cuestionar este diagnóstico con la ayuda del ensayo de Didier Eribon: Regreso a Reims (2009).
Más allá de la ley. La virginidad en la genealogía del liberalismo
Authors: Martínez Rivas Rafael
Published: October 2024

Los estudios foucaultianos sobre la gubernamentalidad neoliberal han prestado mucha atención a la tercera parte de Las confesiones de la carne, en la que Foucault traza la arqueología del “hombre de deseo” y del sujeto jurídico. Sin embargo, la literatura ha tendido a prestar poca atención a la segunda parte del libro, dedicada al estudio de la virginidad. Es esta parte la que este trabajo pretende estudiar, reconstruyendo críticamente los argumentos de Foucault y mostrando el lugar que la virginidad cristiana ocupa en la genealogía del sujeto moderno y de la gubernamentalidad liberal. Por último, el trabajo pretende mostrar que la virginidad cristiana primitiva, tal y como la presentan Brown y Foucault, puede definirse como lo que este último denominó una “contraconducta”.
La línea de unión entre el cuerpo y el alma. Notas sobre la cuestión de la carne en el proyecto de una Historia de la sexualidad
Authors: Yuing-Alfaro Tuillang , Arancibia Carrizo Juan Pablo
Published: October 2024

La propuesta revisa algunas notas temáticas como perspectiva de conjunto del proyecto de una Historia de la sexualidad. Se intenta aportar a la comprensión de la noción de sexualidad en Foucault, a partir de una revisión del decurso que ha tenido en ruptura y continuidad con otros desarrollos conceptuales como los de “cuerpo”, “alma”, “subjetividad” y “carne”, entre otros. En este sentido, la noción de cuerpo como afectado por el poder y la fuerza, permite un vínculo con la noción de carne. Se establece así un recorrido que considera, en un primer momento, las características que toma el cuerpo desde una perspectiva genealógica. Una segunda cuestión trata la particular forma de las fuerzas en el contexto de la Grecia antigua integrada por hombres libres. En un tercer momento se analiza el cuerpo como instancia que, frente a las tecnologías de poder, pone en forma una dimensión simultáneamente individual y social. Luego, se examina el cuerpo como lugar que permite una lectura de la sexualidad como inscripción discursiva ante la que comparece la verdad de los sujetos.
Arqueología y experiencia en la Historia de la sexualidad de Michel Foucault
Authors: Cortés Cuadra Juan Vicente
Published: October 2024

La publicación del cuarto y último volumen de la Historia de la sexualidad viene a llenar una larga espera, pero, sobre todo, ella permite tener por fin una visión de conjunto del último gran proyecto histórico-crítico de Michel Foucault. En el presente trabajo quisiera mostrar que con la publicación de Les aveux de la chair (Paris, 2018) se vuelve posible comprender una serie de dificultades que han sido planteadas por los especialistas relativos al “giro” foucaultiano, a partir de los años 1980, hacia una reintegración de la experiencia en el análisis. En particular, quisiera aquí defender que lo que Foucault llama “la experiencia de sí”, bajo la figura particular de la experiencia moral de la sexualidad, no será concebida ni por referencia a un sujeto, ni por referencia a un objeto (ni tampoco de manera “intersubjetiva”), sino como la formación de un a priori histórico: el de la experiencia de la carne como transformación de sí.
Vida cotidiana y trayectorias vitales situadas de mujeres mayores (AMBA, provincia de Buenos Aires, Argentina): la incidencia de la pandemia por Covid-19
Authors: Silvia Valero Ana , Morgante María Gabriela , Cueto Julián
Published: October 2024

Este trabajo se propone dar cuenta de las intersecciones entre distintos aspectos de la vida cotidiana y las trayectorias vitales de personas mayores en un espacio barrial, y la incidencia de la pandemia por Covid-19. Se basa en el desarrollo sostenido desde 2015 de prácticas integrales que incluyen docencia, investigación y extensión con un grupo de mujeres mayores del barrio El Retiro (Lisandro Olmos, La Plata, área metropolitana de Buenos Aires, provincia de Buenos Aires, Argentina). Se funda en un abordaje metodológico a micro-escala, desde una perspectiva etnográfica. Los resultados advierten sobre el modo en el que las situaciones críticas, como el acontecimiento de la pandemia por Covid-19, pueden constituirse en oportunidades para la reformulación de representaciones sociales y sentidos, como también pueden incluir la generación de redes de apoyo entre las propias personas mayores y con otras generaciones, dentro del barrio e incluso más allá de él.
Convergencias y bifurcaciones en las biografías y autobiografías de intelectuales indígenas de México y Brasil

Published: October 2024

En este artículo presentamos un ejercicio de reflexión sobre los retos que implica la escritura y el estudio de las biografías y autobiografías de intelectuales indígenas en diferentes escenarios geográficos, históricos y políticos: México y Brasil, la época colonial y la modernidad poscolonial. Nuestro análisis comparativo se centrará en las figuras del historiador indígena Domingo Chimalpáin y del activista brasileño Álvaro Tukano. Se trata de ensayar un experimento crítico e imaginativo, que evidencie las dificultades y las limitaciones de nuestra producción de textos académicos sobre la vida de dos intelectuales indígenas, cuya escritura autobiográfica no obedece necesariamente a los criterios literarios, las fronteras y los objetivos impuestos por los géneros occidentales.
Importation et acclimatation de végétaux dans l’ancienne Égypte : la fascination des périphéries (3200 à 900 av. J.-C.)
Authors: Chadefaud Catherine
Published: October 2024

Comment et pourquoi Pharaon, son administration et ses clergés décidèrent-ils d’importer ou d’acclimater certaines espèces végétales ? Quels furent les objectifs économiques, politiques et religieux ? Les périphéries sont explorées de manière pacifique ou belliqueuse selon les contextes comme l’attestent les inscriptions et l’iconographie des temples. Dès l’époque des pyramides, le bois de cèdre est importé du Liban, ses qualités sont appréciées pour la construction des bateaux. Les campagnes militaires de Thoutmosis III font découvrir et acclimater diverses espèces végétales de Syrie-Palestine comme l’attestent les images du « jardin botanique » de Karnak. Cet intérêt se confirme sous Aménophis III. Au Nouvel Empire, sous la XVIIIe dynastie, la reine – régente Hatchepsout organise une expédition commerciale au lointain pays de Pount afin de rapporter des arbres à térébinthe qu’on tente d’acclimater en haute Égypte pour en utiliser la résine.
Administrer les provinces périphériques de l’Empire byzantin du ixe au xie siècle
Authors: Limousin Éric
Published: October 2024

En vertu des principes d’oikonomia et de taxis, l’histoire de l’administration provinciale de l’Empire byzantin doit présenter un visage homogène. Or, à partir du ixe siècle, les provinces périphériques mieux connues en Orient, échappent au schéma ancien. L’enquête, basée sur les taktika mais également sur les apports de la sigillographie montre que les thèmes dits « arméniaques », s’ils présentent un stratège, parfois un kritès, sont administrés différemment. Les populations d’origine orientale (Arabes chrétiens, Arméniens, Géorgiens) occupent les postes de stratège, de duc, mais également les postes plus modestes d’épiskeptitès ou de basilikos. Ainsi passée la phase de conquête, le pouvoir impérial sait s’adapter aux contingences locales et montre une parfaite connaissance des enjeux de contrôle du territoire et d’intégration des élites locales.
L’État épirote : une périphérie byzantine (xiie-xve siècle)
Authors: Osswald Brendan
Published: October 2024

À la suite de la chute de Constantinople et de l’effondrement de l’Empire byzantin en 1204, apparut en Épire un État indépendant qui devint plus tard le « Despotat d’Épire » et exista jusqu’à la conquête ottomane en 1449. Cet État se caractérise à la fois par son indépendantisme politique et sa fidélité à la civilisation byzantine. Il demeura donc culturellement « byzantin », sans pour autant rejoindre l’Empire byzantin restauré par les Paléologues en 1261. Ce faisant, il constitua une périphérie du monde byzantin, refusant tout à la fois de quitter l’aire civilisationnelle byzantine et de se soumettre au centre représenté par Constantinople. L’État épirote constitue donc un modèle alternatif de « byzantinité » : un autre État et un autre modèle politique, mais aussi d’autres formes d’expressions artistiques, notamment dans les domaines architectural et littéraire, dont les œuvres se distinguent de celles produites à Constantinople, en partie grâce à des influences occidentales. Il constitue également, d’un point de vue épistémologique, un sujet de recherche particulier.
Les périphéries ultramarines entre dépendance à l’égard de la métropole et intégration régionale : l’exemple du tourisme dans les destinations de l’hémisphère sud
Authors: Buhot Michel
Published: October 2024

L’outre-mer français peut être triplement caractérisé comme une périphérie : géographiquement, il correspond aux parties les plus éloignées du territoire national ; économiquement, il apparaît comme dominé ou marginalisé ; psychologiquement, il est relégué au statut d’espace exotique. Les territoires étudiés sont les destinations touristiques ultramarines françaises de l’hémisphère sud (Nouvelle-Calédonie, Polynésie française, Réunion). L’enjeu est de comprendre pourquoi ces destinations dépendent trop largement de clientèles métropolitaines malgré la distance qui les sépare de la métropole. L’objectif est d’analyser l’origine des clientèles touristiques dans un monde dans lequel le transport aérien long-courrier est perçu de plus en plus comme une aberration. L’intégration régionale apparaît donc comme une nécessité afin de pérenniser l’activité touristique tout en limitant son impact écologique. Pourtant, la restructuration des clientèles constitue un véritable défi à relever.
Journal de guerre
Authors: Villard Léonie
Published: October 2024

Accablée par la défaite de juin 1940 et dans l’impossibilité d’écrire à ses amis anglophones américains et anglais pour les tenir informés des événements qui se déroulent en France, Léonie Villard entreprend le 17 juin 1940 de rédiger en anglais ce qu’elle observe et comprend de la situation. Tenu avec régularité pendant plus de quatre ans, ce journal se termine à la libération de Lyon en septembre 1944. S’efforçant de prendre du recul, Léonie Villard, qui est professeure de littérature anglaise et américaine à l’université de Lyon, passe des heures l’oreille collée à son poste de radio pour écouter la BBC. Non dénuées d’humour, ces pages relatent pourtant semaine après semaine la dureté de la vie sous l’Occupation à Lyon, mais reflètent aussi le solide réseau d’amitiés et de solidarité que Léonie Villard entretient autour d’elle à Lyon et à Oussiat, où elle réside l’été.
Reception and education of refugee children in Greece: policies and evaluation
Authors: Stergiou Lida , Simopoulos Giorgos
Published: October 2024

The relatively recent presence of refugee students in Greek schools is an educational policy challenge called to respect and safeguard human rights and the rights of children in a democratic and receptive social context. In this paper we present research data that allow us to better understand the reception and education conditions of refugee students as perceived by teachers working with them, but also by the students themselves. Positive steps and choices are intertwined with gaps and shortcomings, making this educational landscape a field in which both the essential inclusive approach of the Greek educational system and the professional development of teachers are tested.
Majority and Immigrant Students’ Positionings towards Refugees as Represented in Media Texts
Authors: Panagaki Nikoletta , Archakis Argiris , Tsakona Villy
Published: October 2024

The recent immigrants’ and refugees’ movements towards western nation-states undermine symbolic national boundaries. Such movements are perceived as a threat to linguistic and cultural homogeneity, and reinforce the reproduction of national discourse. The present study focuses on how majority and immigrant students attending a Greek elementary school position themselves towards the Greek national discourse concerning refugees. Using analytical tools from Critical Discourse Analysis, we demonstrate that both majority and immigrant students reinforce Greek national discourse which takes the form of either racist or humanitarian discourse.
Les chants de l’Émigrec
Authors: Festal-Livanis Solange
Published: October 2024

Nous interrogeons ici les rapports aux chants de l’exil qu’entretiennent depuis la junte des colonels des artistes et des intellectuels grecs exilés en France. Le succès des concerts et des chansons sur le thème de l’exil incite à chercher si, au-delà d’une facilité commerciale pour certains, ces chants ne participeraient pas d’un ancrage nécessaire au gré des différentes crises vécues. Que le chant soit lié à la mémoire émotionnelle invite à se demander aussi s’il n’y a pas une nostalgie de la ξενιτιά. Nous commençons par écouter des témoignages de musiciens grecs exilés dont l’attitude vis-à-vis du chant traditionnel est ambivalente. Nous retrouvons en partie cette attitude ambiguë où nostalgie et mise à distance de l’expérience de l’exil politique se côtoient dans le récit de Vassilis Vassilikos Καφενείον « Εμιγκρέκ » [Kafenion « Émigrec »]. Par ailleurs, Yannis Kiourtsakis a mis l’exil et le rapport à la culture populaire au centre de son écriture. Avec Σαν Μυθιστόρημα (Le Dicôlon) et Εμείς οι άλλοι (Double exil), il trouve une nouvelle forme pour chanter l’impossible nostos.
M. Karagatsis, La Grande Chimère (1953) : les affres de l’acclimatation
Authors: Lecoq Manuel
Published: October 2024

En 1953, M. Karagatsis publie le roman La Grande Chimère, qui clôt la trilogie intitulée S’acclimater sous le soleil de Phivos. La protagoniste, Marina Baret, en butte au mal-être d’une existence provinciale qui l’étouffe, émigre inopinément à bord du navire La Chimère aux côtés de Yannis Reïzis, un armateur grec en escale à Rouen. C’est dans l’espace pourtant confiné et étriqué de l’île de Syros, dans les Cyclades, que la jeune femme s’imagine enfin trouver une issue à sa mélancolie. Cet article démontre que, dans ce roman, la migration, dans une constante intertextualité avec l’Antiquité et la modernité littéraires, est tragiquement associée à la perdition, à l’ennui et à la mort. Marina, en quête d’amour, de vie, et d’ailleurs, échoue à s’affranchir d’une errance stérile et pesante, qui la pousse à sortir hors du monde par l’imagination et l’adultère, en quête d’un idéal fantasmé et caduc, jusqu’à la catastrophe finale.
Entre les terres : questions d’origine, de structure et d’identité dans la revue ΦΡΜΚ
Authors: Tsaita-Tsilimeni Valia
Published: October 2024

Dans le présent travail, nous parlerons de la façon dont la poésie grecque contemporaine – et plus précisément celle publiée dans la revue ΦΡΜΚ – nous expose à une architecture de la migration « moderne » : celle des trajectoires des jeunes Grecs qui sont installés en dehors du pays. Nous révélerons la dentelle des réflexions anthropologiques qui forment la voix poétique actuelle, ainsi que la façon dont l’individu d’aujourd’hui est à la recherche d’une identité. Comment le lieu d’origine est-il concerné par les déplacements continus de ceux qui étaient, alors, ses habitants ? La nouvelle terre d’accueil parvient-elle à obtenir une identité indépendante de celle de la « terre d’exil » ? Les déplacements d’un endroit à l’autre renforcent-ils ou affaiblissent-ils nos impressions de stabilité ? Nous aborderons également des questions de forme afin de montrer comment la partie graphique d’un poème met l’accent sur les traces d’un temps en imprécision dont le flou permet aux nouvelles identités individuelles et collectives de surgir.
L’amané oriental et la muse de Nikos Engonopoulos
Authors: Samouil Alexandra
Published: October 2024

Mon article porte sur Marika Politissa, chanteuse populaire de l’amané oriental dans les années 1930, ainsi que sur son illustration par Nikos Engonopoulos dans son poème “Amazones” (malgré sa structure apparemment illogique) comme Lilith, le démon à prédominance féminine qui, sous forme humaine, aspire la vie de ses victimes en les violant pendant leur sommeil. Cependant, cette illustration de la chanteuse de rébétika d’Asie Mineure s’avère n’être qu’un commentaire sur la récente censure et l’interdiction de l’amané par le dictateur Ioannis Metaxas (1937) ainsi que sur les chanteuses de rébétiko libérées de l’époque, car elles avaient, entre autres, envahi les zones de plaisir sexuel dominées par les hommes. En résumé, Engonopoulos, se démarquant des ennemis du rébétiko – mais aussi de la majorité des poètes de l’époque, voire de tous – met en évidence la dimension culturelle d’un problème social, car les réfugiés d’Asie Mineure ont apporté avec leurs bagages en Grèce leurs mélodies, qui avaient été réduites au silence à Athènes après les café-amans, c’est-à-dire après le dernier quart du xixe siècle.

Kataribe Storytellers
Authors: Ogawa Akiko
Published: October 2024

This chapter examines Japan's unique Kataribe (Storytellers) approach to transmitting firsthand experiences of war and disasters. Historically, Kataribe referred to folklore storytellers, but now includes narrators of modern traumas like war, crime, and natural disasters. Kataribe storytelling, often in museums and local archives, emphasizes personal narratives, contrasting with the more factual Western practices. A key example is in Hiroshima, where school excursions involve listening to atomic bomb survivors' testimonies, a model initiated by a survivor teacher. This emotionally connects students with wartime experiences and fosters involvement. However, as time passes, conveying these experiences become harder due to the lack of shared background, and the authenticity of legacy successors, who are not direct survivors, is questioned. We explore how listeners use their imagination in response to storytellers and the role of faculty and museum staff in maintaining involvement. It concludes with a discussion on media use and the significance of listeners as expressive agents.
Significance of Grassroots Museums and Ainu Culture in Japan
Authors: Tanaka Shunsuke
Published: October 2024

This chapter explores the history of Japanese grassroots museums by focusing on the establishment of museums dedicated to the challenges and distinct culture of the Ainu who are indigenous to northern Japan, including the Hokkaido Island. Recently, the Japanese government has intensified its focus on Ainu-related policies. This includes initiatives, such as the opening of new national museums in Hokkaido. However, the government has faced criticism owing to its failure to fully recognize and protect the rights of the Ainu. The arrest of Ainu individuals practicing traditional fishing methods, political rhetoric from the government, and denial of the existence of the Ainu people by ruling party officials indicate that the approach and policies concerning the Ainu have remained largely unchanged from historically discriminatory practices. There is growing criticism that current Ainu policies primarily view the Ainu as mere “tourist attractions” rather than a community with distinct rights and cultural heritage.
