Tektite production as a standard process in large terrestrial impact craters Pierre Rochette1,*ORCID iD , Luigi Folco2ORCID iD , David Baratoux (++...)

https://www.academia.edu/3143-6692/1/3/10.20935/AcadEPS8473 Tektites are terrestrial macroscopic silica-rich glasses generated by meteoritic impacts. We propose here an up-to-date review of the characteristics of tektites considering the three newly documented strewn fields. Diagnostic criteria that make sense in terms of a common genetic process emerge from these characteristics and enable their discrimination from other types of impact-glass strewn fields. The seven strewn fields that qualify include the four classic ones (Australasian, Central European, Ivory Coast and North American) plus ananguite, belizite and geraisite strewn fields. Their age spans the 0.8 to 35 Ma range. In addition, the urengoite case is considered to be a strong candidate for a tektite strewn field despite the low number of finds. If one also considers the uruguaite putative candidate strewn field and the three microtektite-only strewn fields, the age span extends to the Cretaceous–Paleogene (K–Pg) layer. The number of known impact craters with diameters >10 km and well-defined ages younger than 66 Ma is fifteen. In addition, six impact events, for which no craters have yet been found, may have produced strewn fields during the 0–66 Ma interval. Therefore, 57% of large impact events in the 0–66 Ma period may have produced tektites or microtektites. Restricting the count to only the seven proven tektite strewn fields, the proportion is 39%. This figure drops to zero for known craters older than 66 Ma. On the other hand, of the large known or presumed craters, 100% of those younger than 3 Ma and 88% of those younger than 30 Ma have generated tektites. Therefore, considering the increasing probability of tektite strewn fields to be erased through time, we conclude that tektite production is likely the rule rather than the exception in large terrestrial impact craters. https://www.academia.edu/journals/academia-earth-and-planetary-science/articles?source=journal-top-nav

Eu faraó e você? Margaret Bakos Pedro Paulo A . Funari

https://www.academia.edu/180148030/Eu_fara%C3%B3_e_voc%C3%AA_Margaret_Bakos A História Antiga, nas últimas décadas, tem estado cada vez mais atenta às transformações epistemológicas nas Ciências Humanas. No despertar da historiografia no século XIX, o estudo da Antigüidade desempenhou papel de destaque, a começar pelas próprias origens antigas do gênero literário. Nestas primeiras décadas, o político, como locus, mostrou-se fecundo, centrado, primeiro, nos grandes personagens, para depois se espraiar por toda uma gama de relações de poder. O século XX testemunharia um multiplicar-se da influência seminal dos estudos de História Antiga, numa pletora de campos, tanto historiográficos como de outras ciências. Democracia antiga e moderna, razão e pensamento, escravidão, alguns dos muitos temas explorados por estudiosos da Antigüidade, lidos, contudo, por historiadores em geral, e por todos que se preocuparam com o humano. Não cabe dúvida, portanto, que a História Antiga nunca saiu da ribalta acadêmica (e, menos ainda, da cena pública). Nunca se escreveu, falou, filmou, representou tanto sobre a Antigüidade. O primeiro objetivo desta coletânea, assim, relaciona-se a essa posição privilegiada do estudo da Antigüidade. Busca, além disso, mostrar como as discussões epistemológicas mais recentes aparecem na literatura brasileira. Desde meados do século XX, surgiram movimentos sociais que contestaram o caráter homogêneo e monolítico das sociedades. Para dar conta de tais conflitos e divisões sociais evidentes, diversas vertentes vieram a questionar o que se convencionou chamar de modelos normativos de interpretação da vida social. A teoria social propôs que as identidades eram algo relevantetema não tão presente anteriormente -e que elas eram fluidas, mutantes e EU FARAÓ. E VOCÊ? MARGARET M. BAKOS 1 Osíris é uma das mais importantes divindades do Antigo Egito, sendo associado à morte, à ressurreição e à fertilidade. Representado por uma múmia de cujas bandagens saem as mãos, segurando o cajado e o chicote, símbolos do poder faraônico, ele usa uma coroa branca, alta, flanqueada por duas plumas; seu corpo, às vezes, aparece em cor branca, outras, em preta, significando o aluvião do Nilo, outras ainda em verde, em alusão ao seu poder de ressurgimento 2 . Observando esse mito, caberia perguntar: como se construiu esse sincretismo identitário entre a divindade e o governante do Antigo Egito? São os homens que explicam os deuses, e não o contrário, ensina Jean-Pierre Vernant, a respeito dos gregos 3 . E a história dos faraós, cujo nome, em hieroglifos, significa casa grande, confirma a postura do helenista. Na relação entre esses governantes e os deuses, a figura do faraó egípcio, sua titulação e os símbolos de seu poder foram-se constituindo lentamente através da

Agency in the age of generative AI: a critical review of educational implications Jasper Roe1,* , Mike Perkins2

https://www.academia.edu/3071-0286/2/3/10.20935/AcadAI8422 Conversations regarding the societal implications of artificial intelligence (AI) and its integration into educational processes are ongoing. An area of great significance in this regard is agency, including how the use of AI technologies impacts an individual’s ability to exercise autonomy. In educational contexts, this remains a relatively unexplored yet vital subject. To shed light on this subject, this paper provides an exploratory thematic review of works which investigate the relationship between generative artificial intelligence (GenAI) and agency in education, mapping and interpreting the available literature through the lens of critical digital pedagogy (CDP). The findings suggest that while GenAI may enhance learner agency through personalisation and support, it also risks exacerbating educational inequalities and diminishing learner autonomy in certain contexts. This review also contributes to new sociotechnical perspectives on AI, highlighting how GenAI technologies may shape and be shaped by power dynamics and pedagogical ideologies. This review contributes to the existing debate on how AI technologies can be deployed in education and society responsibly by exposing how the use of these technologies may lead to unintended impacts, including the entrenchment of inequality and the reshaping of concepts of individual agency, authorship, and autonomy.

Représentations sociales des Ivoiriens à l'égard des migrants burkinabés, maliens et nigériens à Bouaké depuis les reconfigurations géopolitiques de 2023 European Scientific Journal ESJ

https://www.academia.edu/180274900/Repr%C3%A9sentations_sociales_des_Ivoiriens_%C3%A0_l%C3%A9gard_des_migrants_burkinab%C3%A9s_maliens_et_nig%C3%A9riens_%C3%A0_Bouak%C3%A9_depuis_les_reconfigurations_g%C3%A9opolitiques_de_2023?email_work_card=title Cette étude vise à analyser les représentations sociales construites par les Ivoiriens à l’égard des migrants burkinabés, maliens et nigériens à Bouaké, dans un contexte de reconfiguration géopolitique régionale de 2023. Elle adopte une approche qualitative fondée sur des entretiens semi-directifs menés entre février et mars 2026 auprès de 33 acteurs, dont des migrants des pays de l’AES et des Ivoiriens résidant à Bouaké, au centre de la Côte d’Ivoire. Les données ont fait l’objet d’une analyse thématique et la théorie des représentations sociales de Moscovici a servi de cadre théorique. Les résultats montrent qu’avant les reconfigurations géopolitiques de 2023, les représentations sociales des Ivoiriens à l’égard des migrants des pays de l’AES à Bouaké se construisaient à travers les interactions sociales quotidiennes. Elles reposaient également sur la reconnaissance de leurs compétences professionnelles et de leur utilité économique. Ainsi, ils étaient représentés comme des personnes socialement intégrées, des partenaires commerciaux fiables et des travailleurs qualifiés. Cependant, après les reconfigurations géopolitiques de 2023, les données révèlent une évolution différenciée des représentations sociales. Cette transformation se caractérise par une politisation et une catégorisation des identités nationales de ces migrants et par une suspicion politico-sécuritaire. Parallèlement, les relations économiques entre les Ivoiriens et les migrants des pays de l’AES se maintiennent, tandis que l’ancienneté de résidence à Bouaké apparaît comme un facteur clé de l’intégration sociale des migrants. This study aims to analyze the social representations constructed by Ivorians regarding Burkinabé, Malian, and Nigerien migrants in Bouaké, within the context of the regional geopolitical reconfiguration of 2023. It adopts a qualitative approach based on semi-structured interviews conducted between February and March 2026 with 33 participants, including migrants from AES countries and Ivorians residing in Bouaké, in central Côte d'Ivoire. The data underwent thematic analysis, and Moscovici's theory of social representations served as the theoretical framework. The results show that prior to the geopolitical reconfigurations of 2023, Ivorians' social representations of migrants from AES countries in Bouaké were constructed through daily social interactions. These representations were also based on the recognition of their professional skills and economic value. Thus, they were portrayed as socially integrated individuals, reliable business partners, and skilled workers. However, following the geopolitical shifts of 2023, the data reveal a differentiated evolution in social perceptions. This transformation is characterized by the politicization and categorization of these migrants' national identities and by a politico-security suspicion. At the same time, economic relations between Ivorians and migrants from the Alliance of Sahel States countries have been maintained, while length of residence in Bouaké appears to be a key factor in the social integration of migrants.

Commentary: Qi, J. et al. Towards trustworthy agentic AI: a comprehensive survey of safety, robustness, privacy, and system security. Acad. AI Appl. 2026, 2, 8260 Anastasios Stavropoulos1,2,*

https://www.academia.edu/3071-0286/2/3/10.20935/AcadAI8435 This survey offers a rigorous and welcome map of agentic artificial intelligence (AI) trustworthiness, organised around two dimensions the authors identify as critical for high-risk deployment: safety and robustness, and privacy and system security. By design, the survey treats value alignment, transparency, fairness, and accountability as relevant contexts rather than as core dimensions. This commentary advances a friendly amendment: accountability is not a peripheral dimension that can be deferred, but the binding constraint on agentic-AI trustworthiness. The reason it resists the survey’s stage-targeted, technical treatment is structural and temporal. Accountability mechanisms are deliberative and operate at human, institutional speed; agentic systems act autonomously, continuously, and at scale. This asymmetry—a governance lag—means that even a fully implemented suite of technical mitigations leaves a residual gap that only governance can close, while prevailing governance instruments remain calibrated to human-paced oversight. A complete trustworthiness agenda must therefore foreground accountability as a first-order design and governance problem. https://www.academia.edu/journals/academia-ai-and-applications/articles?source=journal-top-nav

Modèle d'évaluation intégrée de la performance financière et territoriale des communes marocaines : cadre méthodologique et opérationnel European Scientific Journal ESJ

https://www.academia.edu/180214212/Mod%C3%A8le_d%C3%A9valuation_int%C3%A9gr%C3%A9e_de_la_performance_financi%C3%A8re_et_territoriale_des_communes_marocaines_cadre_m%C3%A9thodologique_et_op%C3%A9rationnel Face aux impératifs de la régionalisation avancée au Maroc, les communes peinent à disposer d'outils d'évaluation adaptés à la complexité de leurs missions. Cet article cherche à déterminer dans quelle mesure un modèle d'évaluation intégrant les dimensions financière, économique et sociale, environnementale et celle des grands projets d'investissement (GPI) permet de rendre compte plus fidèlement des contraintes structurelles et du potentiel de développement des communes marocaines, par rapport aux approches comptables classiques. Pour y répondre, cet article présente le Modèle d'Analyse Financière Généralisable (MAFG), un cadre méthodologique et opérationnel conçu pour évaluer la performance financière des collectivités locales marocaines. Élaboré selon une démarche participative et itérative menée auprès de communes des provinces de Zagora et de Midelt, le MAFG s'articule autour de cinq axes interdépendants - solvabilité et autonomie financière, efficience des dépenses, retombées économiques et sociales, transition écologique, et coûts-bénéfices des grands projets d'investissement (GPI) - et intègre 95 indicateurs qualitatifs et quantitatifs. Les résultats de la phase de conception et de pré opérationnalisation révèlent trois constats structurels majeurs : une dépendance excessive aux transferts de TVA de l'État (représentant jusqu'à 88 % des recettes dans certaines communes), une sous-exploitation du potentiel fiscal lié aux ressources naturelles et aux grands projets d'investissement, et des inefficiences persistantes dans l'exécution budgétaire, notamment dans les secteurs sociaux et environnementaux. Sur la base de ces constats, cette recherche propose un modèle composite de scoring qui conjugue cadre conceptuel, grille d'évaluation et tableau de bord stratégique pour une aide à la décision multidimensionnelle, avec un score synthétique par axe, un suivi dynamique et un pilotage budgétaire opérationnel, le tout ancré dans les spécificités des communes marocaines et intégrant de manière originale les GPI. Le MAFG est un modèle proposé et pré-opérationnalisé : sa validation empirique systématique est en cours, et les constats présentés relèvent de l’analyse financière préliminaire et non d’une validation du modèle. In the context of Morocco's advanced regionalization reforms, municipalities struggle to access evaluation tools adapted to the complexity of their responsibilities. This article examines to what extent an evaluation model that integrates financial, economic and social, environmental, and major investment project (GPI) dimensions can capture the structural constraints and development potential of Moroccan municipalities more faithfully than conventional accounting-based approaches. To address this question, this article presents the Generalizable Financial Analysis Model (MAFG), a methodological and operational framework designed to assess the financial performance of Moroccan local authorities. Developed through a participatory and iterative process conducted with municipalities in the provinces of Zagora and Midelt, the MAFG is structured around five interdependent dimensions — solvency and financial autonomy, expenditure efficiency and budgetary governance, economic and social impacts, ecological transition, and cost-benefit analysis of major investment projects, incorporating 95 qualitative and quantitative indicators. The results of the design and pre-operationalization phase reveal three major structural findings: an excessive dependence on State VAT transfers (accounting for up to 88% of revenues in certain municipalities), an under-exploitation of fiscal potential linked to natural resources and major investment projects, and persistent inefficiencies in budget execution, particularly in the social and environmental sectors. Based on these findings, this study proposes a composite scoring model that combines a conceptual framework, an evaluation grid, and a strategic dashboard to support multidimensional decision-making, featuring a summary score for each axis, dynamic monitoring, and operational budget management — all grounded in the specific characteristics of Moroccan municipalities and incorporating GPI in an innovative way. The MAFG is a proposed and pre-operationalized model: its systematic empirical validation is under way, and the findings reported derive from the preliminary financial analysis rather than from a validation of the model.

Paradigmas en la investigación: Enfoque cuantitativo y cualitativo European Scientific Journal ESJ

https://www.academia.edu/180423708/Paradigmas_en_la_investigaci%C3%B3n_Enfoque_cuantitativo_y_cualitativo?email_work_card=title Throughout the history of science have emerged various schools of thought such as empiricism, Dialectical Materialism, Positivism, Phenomenology etc. Which have led to different paths in pursuit of knowledge, though in recent decades such currents have been polarized into two main approaches: the quantitative approach and the qualitative approach to research. In this review, both approaches are defined, the process steps of the investigation are presented generically and applies both perspectives, defines the characteristics of each paradigm and proposes a vision for research that involves the possibility of mixing two modes in the generation of knowledge in the same study, which called for multi-method approach. A lo largo de la historia de la ciencia han surgido diversas corrientes de pensamiento tales como el Empirismo, el Materialismo Dialéctico, el Positivismo, la Fenomenología etc. Las cuales han originado diferentes vías en búsqueda del conocimiento, sin embargo en las últimas décadas tales corrientes se han polarizado en dos enfoques principales: el enfoque cuantitativo y el enfoque cualitativo de la investigación. En la presente revisión, se definen ambos enfoques, se presentan las etapas del proceso de la investigación de manera genérica y las aplica en ambas perspectivas, define las características de cada paradigma y propone una visión respecto a la investigación que implica la posibilidad de mezclar lasdos modalidades en la generación del conocimiento en un mismo estudio, el cual de denomina enfoque Multimétodo.
