Published: April 2024

Este estudio se centra en investigar la integración de la tecnología educativa en el aula de educación básica en Ecuador, con el objetivo de comprender su impacto y los desafíos asociados. La metodología empleada combina técnicas cualitativas y cuantitativas para recopilar datos e información relevante. Se realizan entrevistas semiestructuradas con docentes y directivos escolares, así como la distribución de cuestionarios a estudiantes para obtener una visión holística del tema. Los resultados muestran que la mayoría de los docentes utilizan tecnología de manera regular en sus clases, pero que existe una falta de infraestructura tecnológica en muchas instituciones educativas. Además, se identifican desafíos significativos relacionados con la capacitación docente y la equidad en el acceso a dispositivos y conectividad. Estos hallazgos tienen implicaciones importantes para la práctica educativa y el desarrollo de políticas públicas en Ecuador. En conclusión, este estudio destaca la necesidad de fortalecer la capacitación docente y mejorar la infraestructura tecnológica en las escuelas para garantizar una integración efectiva de la tecnología en el aula de educación básica. Además, subraya la importancia de abordar las inequidades en el acceso a la tecnología como parte de un enfoque integral de inclusión digital en el sistema educativo del país.
Propagación Mediante Embriogénesis Somática de Especies Arbóreas Tropicales: Un análisis del Estado Actual del Conocimiento
Authors: Paredes Ulloa Christopher Oswaldo , Machado Cuzco Jessica Alexandra , Sucoshanay Villalba Darwin Javier , Viafara Derwin
Published: April 2024

La creciente importancia de la biotecnología vegetal y particularmente de la embriogénesis somática está sustentada en la necesidad de una mayor propagación de especies de interés productivo y en la conservación de la biodiversidad. En el ámbito forestal constituye una técnica en creciente fomento durante los últimos años como herramienta útil para la propagación de especies a gran escala. En este trabajo de revisión se abordan aspectos teórico-prácticos que sustentan el desarrollo de embriogénesis somática, con énfasis en especies forestales tropicales, así como una prospección de las principales tendencias en las publicaciones disponibles en la base de datos SciELO sobre esta temática. Las evidencias científicas demuestran la utilidad de la embriogénesis somática como técnica de biotecnología vegetal que favorece la propagación de especies de interés agrícola y forestal. La literatura disponible en SciELO sobre esta temática refleja mayor aplicación de la embriogénesis somática en especies agrícolas; sin embargo, más del 30 % de los artículos abordan especies forestales, aunque destacan Coffea spp. y Theobroma cacao como las más estudiadas. También se aprecia que son más frecuentes los estudios en diferentes cultivares y/o explantes y con reguladores de crecimiento. Estos resultados sugieren que deben fomentarse todavía las iniciativas dirigidas a la implementación de la embriogénesis somática como alternativa sostenible en la propagación de forestales tropicales.
Patronagem e profissionalização da burocracia : o que nos dizem os estados brasileiros?
Authors: Lopez Felix Garcia , Palotti Pedro , Gomide Alexandre
Published: April 2024

O foco de análise deste capítulo recai sobre o recrutamento por meio da patronagem. Essa análise apresenta três achados principais. O primeiro é que o recrutamento por seleção competitiva é amplamente majoritário, mas não se verificam trajetórias lineares de ampliação da profissionalização burocrática nas últimas duas décadas. Em outros termos, por esta métrica, a profissionalização dos quadros não é uma tendência geral. O segundo achado é que a burocracia dirigente estadual padece de um problema que também caracteriza, embora com menor intensidade, a burocracia dirigente federal: a alta rotatividade. O terceiro achado é que as características dos quadros administrativos dos estados são heterogêneas, apresentando grande variação entre si. Há trajetórias ou perfis díspares entre os estados em todas as dimensões aqui analisadas.

Authors: Ribeiro Manuella Maia , Macaya Javiera , Storino Fabio , Portilho Luciana , Barbosa Alexandre Fernandes , Cunha Maria Alexandra Viegas Cortez da
Published: April 2024

O capítulo tem como objetivo a proposição de uma análise multidimensional da presença de capacidades estatais em TICs e de habilidades digitais e uso de tecnologias por cidadãos, com foco nos estados brasileiros e no seu papel para acelerar a adoção das TICs tanto pelo setor público como pela sociedade. Para isso, são utilizados os dados das pesquisas TIC Domicílios e TIC Governo Eletrônico, realizadas regularmente pelo Cetic.br/NIC.br ligado ao Comitê Gestor da Internet no Brasil (CGI.br). Os desenhos amostrais de ambas as pesquisas permitem análises nacionais representativas para suas respectivas populações-alvo. Para este capítulo, são analisados os resultados da última edição das pesquisas TIC Governo Eletrônico, coletada em 2019, e uma combinação das amostras de 2018 e 2019 da TIC Domicílios, a qual permitiu apresentar os indicadores deste estudo por estado.
Tribunais de contas estaduais : controle ou avaliação de políticas públicas?
Authors: Lopes Gustavo Andrey Fernandes , Grin Eduardo José , Teixeira Marco Antônio Carvalho , Rehner Marcos
Published: April 2024

O objetivo deste capítulo consiste em analisar o processo de implementação do IEGE enquanto instrumento de avaliação, sobretudo, da qualidade na adoção de mecanismos de governança pública nos governos estaduais. Busca-se também abordar as heterogeneidades na frequência de sua aplicação e nas variações metodológicas entre os estados. A atuação das cortes de contas no ciclo de políticas públicas e de ações governamentais vem crescendo de forma acentuada na administração pública brasileira. Para além de sua função precípua de analisar as contas públicas, estes órgãos de controle têm também intensificado suas atividades de avaliação.
Ações afirmativas nos estados brasileiros : o caso da reserva de vagas para população negra em concursos públicos
Authors: Silva Tatiana Dias
Published: April 2024

Este capítulo procura apresentar um panorama da adoção de medidas afirmativas para ingresso de negros no setor público no âmbito dos governos estaduais. Para tanto, a partir dos arcabouços normativos aprovados, serão caracterizados os sistemas de ações afirmativas, por meio de padrões e tendências relativas às medidas adotadas pelos estados e como se relacionam com a institucionalidade federal. Além disso, será objeto de atenção o contexto institucional em que as normas foram adotadas e os elementos suscitados para sua adoção (de onde partiu a iniciativa e a justificativa apresentada). Ao final, serão apresentadas as considerações sobre esse processo de implementação e suas repercussões para a efetividade da norma e articulação com a dinâmica nacional de enfrentamento às desigualdades raciais.

Estados : o elo perdido da cadeia federativa?
Authors: Souza Celina
Published: April 2024

Este capítulo analisa a trajetória dos estados brasileiros ao longo da institucionalização do federalismo. De protagonistas políticos desde a constituição da República até a era Vargas, os dirigentes estaduais só voltaram a adquirir visibilidade no cenário nacional com a chegada da covid-19. A pandemia tirou dos bastidores uma das muitas tensões inerentes a todo sistema federal, ou seja, a competição em torno de quem decide, quem coordena, quem implementa e quem financia as políticas públicas. Em algumas federações, como o Brasil, entendimentos divergentes entre o governo federal e os estaduais sobre os métodos para enfrentar o vírus foram objeto de notícias diárias na mídia. O debate foi levado à decisão do Supremo Tribunal Federal (STF), que, rompendo sua tradição de julgar a favor da União nas disputas federativas, reconheceu a competência concorrente das três esferas para adotar procedimentos de combate à pandemia. Assim, no vazio deixado pelo governo federal, foram os governadores que assumiram a liderança das medidas preventivas e coordenaram questões sensíveis, como a compra de equipamentos no exterior, a criação de grupos de especialistas e a formação de consórcios, desempenhando um papel de destaque no jogo federativo.

O Papel dos estados na normatização dos conselhos municipais de políticas públicas
Authors: Lavalle Adrian Gurza , Guicheney Hellen , Bezerra Carla
Published: April 2024

Este capítulo demonstra, com evidências sistemáticas, a importância dos estados para a expansão territorial e para a operação dos conselhos nos municípios do país. Argumentamos que, não obstante a importância da regulação nacional, e a depender do subsequente grau de discricionariedade deixado por ela aos níveis subnacionais, certas características dos estados – como trajetória da política, perfil econômico e sociodemográfico, capacidades estatais ou densidade associativa – podem estimular a proatividade de governos estaduais no que se refere à determinação das atribuições (ou à especificação institucional) e dos padrões de expansão territorial dos conselhos.
‘Anybody can do sculpture, it is purely mechanical’: Harriet G. Hosmer and the relation between sculpture, reproduction and machine invention
Authors: Altinoba Buket
Published: April 2024

This article examines the work of Harriet Goodhue Hosmer, focusing on her unique approach to sculpture in the context of evolving ideologies and technological advances in the nineteenth century. The various facets of her life and career, shaped by the collaborative nature of sculpture making in this period, shed light on her identity as both a sculptor and inventor. Hosmer’s work and aspirations to be a harbinger of a new status for women that celebrated female strength and power can be seen against the backdrop of several nineteenth-century freedom movements, but also the emergence of spiritualism in the United States. Exploring invention, authorship and reproduction and revealing the processes of making sculpture in different sizes and materials, this article also incorporates notions of gender by discussing Hosmer and her goal of creating surrogates and machine inventions, considering the mutual interaction of body and technology. Hosmer’s success and her dedication to inventions is drawn out alongside the challenges she faced as a female sculptor in a male-dominated field. Drawing on Gilbert Simondon’s insights into invention, the article suggests that Hosmer’s commitment to invention and the ownership of her creations not only established her as a professional inventor, but also secured her an enduring place in the history of art and science.
ransformations of Currents in Sigma-Models with Target Space Supersymmetry
Authors:   Institute of Physics of the Czech Academy of Sciences, Czech Republic, Bernardes Vinicius , Mikhailov Andrei ,   Universidade Estadual Paulista, Brasil, Viana Eggon ,   Universidade Estadual Paulista, Brasil
Published: April 2024

We develop a framework for systematic study of symmetry transformations of sigma-model currents in a special situation, when symmetries have a well-defined projection onto the target space. We then apply this formalism to pure spinor sigma-models, and describe the resulting geometric structures in the target space (which in our approach includes the pure spinor ghosts). We perform a detailed study of the transformation properties of currents, using the formalism of equivariant cohomology. We clarify the descent procedure for the ''universal'' deformation corresponding to changing the overall scale of the worldsheet action. We also study the contact terms in the OPE of BRST currents, and derive some relations between currents and vertex operators which perhaps have not been previously acknowledged. We also clarify the geometrical meaning of the ''minimalistic'' BV action for pure spinors in AdS.
A fitted approximate method for solving singularly perturbed Volterra–Fredholm integro-differential equations with an integral boundary condition

Quasar Winds Caught on Acceleration and Deceleration
Authors: Yi Weimin , Hall P. B. , Yuan Zunli , Brandt W. N. , Schneider D. P. , He Zhicheng , Bai Jin-Ming , Wu Xue-Bing
Published: April 2024

We present an observational study of wind acceleration based on four low-ionization broad absorption line (BAL) quasars (J0136, J1238, J1259, and J1344). J0136 and J1344 (group 1) are radio-quiet and show large BAL-velocity shifts as opposed to stable line-locking associated absorption lines (AALs). Notably, J1344 displays a linear relation between BAL-velocity shift and time interval over three consecutive epochs, characteristic of compelling evidence for BAL acceleration. J1238 and J1259 (group 2) exhibit small BAL-velocity shifts along with steep-spectrum, weak radio emission at 3.0 and 1.4 GHz. All four quasars have spectral energy distributions (SEDs) with a peak at λ
rest ∼ 10 μm, suggesting a link between the BAL acceleration and hot dust emission. The group-2 quasars are redder than group-1 quasars and have a steeper rise at 1 μm < λ
rest < 3 μm in their SEDs. All but J1238 exhibit a steep rise followed by a plateau-like time evolution in BAL-velocity shift. Our investigations, combined with previous studies of BAL acceleration, indicate that (1) the coupling process between the BALs and the interstellar medium (ISM) is one of the major avenues for the origin of quasar reddening and patchy obscuration, (2) AAL outflows are ubiquitous and likely signify large-scale remnants of BAL winds coupled to the ISM, and (3) wind deceleration that is closely linked to the BAL–ISM coupling process may produce weak radio emission in otherwise radio-quiet quasars.
Cognitive Warfare as a New Dimension of Security. A Fictional Concept or a Real Silent Threat?
Authors: Drmotová Kristýna , Kutěj Libor
Published: April 2024

Cognitive warfare is a new phenomenon that differs from any forms of action previously used in the information space aiming to affect the thinking of target groups. The main difference consists in the targeted and sophisticated use of scientific knowledge from neuroscience, with special attention on consciousness and perception of reality. This deeper understanding of how the human mind works has impacted distributed narratives and the choice of the most suitable technological platforms for their distribution to the target audience. This article presents a conceptual classification of cognitive warfare and defines its three core segments: neuroscience, technology and aspects of social science.
Crowdsourcing as an Element of Strategic-Operational Intelligence. How NATO Used it and Changed the Game
Authors: Pešek Karel , Vojtek Jozef , Kutěj Libor
Published: April 2024

The article focuses on the concept of crowdsourcing in the social networking environment as a new phenomenon involving civilians in the intelligence process, enabling the use of their intelligence potential during armed conflict. Crowdsourcing of the civilian population is introduced by the example of NATO intervention during the first civil war in Libya. The article presents its use during the intelligence process at the strategic-operational level of command and control of the armed forces. It establishes its possible definition as a collection method of the intelligence process, and as a collection method which is disjunctively separable from similar intelligence collection methods.

Les complications post-coloscopie
Authors: Loly Jean-Philippe
Published: April 2024

La coloscopie est l’un des actes endoscopiques les plus réalisés dans le monde. Elle reste considérée comme un acte invasif à faible risque. Néanmoins, son utilisation à titre diagnostique est liée à de nombreuses potentielles complications. Par ailleurs, le développement de nouvelles techniques thérapeutiques associées à la coloscopie majore le risque de complications. L’immense majorité des complications liées à la coloscopie sont de bon pronostic, et même si elles sont pour la plupart imprévisibles et résultent le plus souvent d’un aléa thérapeutique, il est cependant nécessaire de les connaître pour pouvoir les identifier et appliquer une prise en charge adéquate afin de ne pas grever le pronostic du patient . Dans ce premier article, le docteur Jean-Philippe Loly se penche sur les facteurs de risque de complications à la suite d’une coloscopie . Dans un second article, qui sera publié dans le prochain numéro, le docteur Jean-François Gigot se penchera sur les points d’attention pour l’expert confronté à de telles situations .
L’écobiologie, une démarche philosophique singulière et anticipatrice de soin de la peau
Authors: Déchelette Corinne , McEwen Laurel , Granet-Abisset Anne-Marie
Published: April 2024

L’écobiologie est une démarche intégrative des soins de la peau créée par Jean-Noël Thorel, président fondateur de l’entreprise NAOS. Replacée dans le contexte de l’époque de sa création en 1977 où la cosmétique était limitée à une offre basique d’hygiène et de soin, cette vision des soins de la peau était novatrice et avant- gardiste. Aujourd’hui, l’entreprise et la société dans laquelle elle évolue ont changé, ce qui conduit fréquemment à confondre l’écobiologie avec l’écologie et à atténuer le caractère anticipateur de cette démarche écobiologique de soin de la peau. Nous avons voulu comprendre cette vision singulière des soins de la peau depuis son émergence en interviewant l’inventeur et dans son amalgame avec l’écologie. Au terme d’une réflexion croisée, il s’avère que la confusion systématique écobiologie / écologie n’engendre pas de mécompréhension notoire du terme écobiologie dans le sens où elle renvoie à un archétype de connexion entre l’humain et la nature, un idéal qui sous-tend la pensée écobiologique.
Qu’un sens impur…

Published: April 2024

Le sens est un insaisissable. On structure ce que l’on en peut entendre avec le langage, mais les mots sont insuffisants. Dans le champ de la signifiance tout est affaire de circonscription. Suivant cette logique, l’être de langage, s’il aspire à sortir du cercle, il lui faut apprendre à chanter. Parce que l’inexplicable, au croisement des refrains, on le raconte avec une langue à soi, sur un air qui nous est propre et inscrit au sein d’un contexte pluriel. Cela permet sans doute la plus honnête des expressions. Production décalée du sens, musicalité retrouvée ; œuvre de vie stabilisée.

Covid-19 et responsabilité pénale en milieu professionnel
Authors: Tchatchouang Tchejip Rodrigue
Published: April 2024

L’analyse de la thématique « Covid-19 et responsabilité pénale milieu professionnel » vise à s’appesantir sur les considérations de la Covid-19 dans la mise en œuvre de la responsabilité pénale en milieu professionnel. Il s’agit de questionner son influence dans la mise en œuvre de la responsabilité pénale en milieu professionnel. Il est évident qu’entre la santé et la liberté, les agents en milieu professionnel devront à l’occasion de cette pandémie contrôler leur attitude personnelle et collective pour éviter la contamination et préserver leur santé, ou éviter la responsabilité pénale qui pourrait résulter de leurs agissements. Cette double action de l’agent illustre la double considération que l’on peut avoir de la Covid -19 face à la responsabilité pénale en milieu professionnel. D’abord qu’elle serait prise en considération pour établir le fondement de la responsabilité pénale, mais aussi qu’elle s’illustre comme une variable de détermination des pénalement responsables.
Retour sur la réglementation des conflits d’intérêts dans l’acte uniforme relatif au droit des sociétés commerciales et du groupement d’intérêt économique
Authors: Takafo-Kenfack Didier , Ndam Ibrahim
Published: April 2024

Afin d’éradiquer les conflits d’intérêts ou, à tout le moins, d’en réduire les risques de survenance et promouvoir une meilleure gouvernance d’entreprise, le législateur OHADA a institué un corpus de règles en la matière. À la première observation, on peut hâtivement conclure que les objectifs poursuivis par le législateur africain ont été atteints dans les marges significatives. Substantiellement, il n’en est rien, les règles établies s’étant révélées relativement lacunaires et insuffisantes pour lutter efficacement contre ces conflits. Ce résultat mitigé incite à envisager une refonte du régime juridique des conflits d’intérêts si on veut maîtriser une telle gangrène dans l’espace OHADA.
Remote air traffic control towers: An application in Portugal
Authors: Martins Miguel , Silva Jorge , Alves Carlos
Published: April 2024

Purpose: Remote control towers are the latest evolution in air traffic control at the airport level. These towers replace traditional air traffic control towers, moving the airport's air traffic controllers to a remote location called a remote control center. This concept was introduced with the main aim of combating the shortage of air traffic controllers, as well as making it possible to provide several airports with control that, until then, they did not have or were at risk of losing, because of the costs associated with this service. This makes it important to study this solution in Portugal, as there are many airdromes where having runway control may not be economically viable. The study will focus on a project by NAV Portugal, which is about to implement this solution on some islands in the Azores archipelago.Design/methodology/approach: Having identified the number of movements per month at a few chosen airports, the operational viability was studied according to the number of movements per hour to ensure that several restrictions were met.Findings: Even including the region's main airport, from the point of view of analyzing the number of movements, the installation of a remote control tower is feasible. There is also a substantial economic gain from this new solution, both in terms of implementation and operations.Originality/value: Remote control towers are a new air traffic control solution, making it possible to extend this service to countless airdromes that may be in the process of losing this service for economic reasons, or no longer are controlled by an air traffic controller.
Engaging Undergraduate Nursing Students in Collaborative Research
Authors: Sullivan Louise , McCarty Ellen F. , Wood Emily , Cabral Emily
Published: April 2024

Background

Nurses are expected to base practice on evidence from research, which requires an understanding of the research process. However, baccalaureate nursing students may find research courses uninteresting or feel unprepared to conduct research. Participation in experiential research projects may affect their research attitudes, knowledge, and skills.

Method

Nursing investigators engaged nursing students in an experiential, active learning research project centered on the effects of pet interaction involving university students. Faculty mentored and partnered with nursing students, immersing them in all research processes.

Results

Students confirmed that participation in the project enhanced their understanding of research, improved their clinical and communication skills, and fostered professional growth. Students presented results in a scientific poster at the University's research event.

Conclusion

Collaborative faculty-student research projects enhance students' interest in and appreciation of evidence-based research, and support professional development, confidence in assuming research roles, and feelings of connection with faculty, each other, and the university.

Scoping review on severe asthma: Cytokines, cells, triggers and multi-omics approaches
Authors: Du Hongchun , Zhang Min , Gao Jinming , Zhang Youming
Published: April 2024

Severe asthma (SA) is a refractory condition that does not respond well to conventional treatments. Patients with SA have heterogenetic endotypes. Endotypes for SA can be classified as type 2 cytokine-high and type 2 cytokine-low. The condition can also be classified as eosinophilic, neutrophilic, mixed, and paucigranulocytic SA. Abnormalities in TH1 and TH17 cytokines can be present in some SA patients. Innate lymphoid cells, airway smooth muscle cells, and lung epithelial cells have important roles in the disease. Viral infections, bacterial infections, fungal infections, smoking, allergens, and pollutants are major triggers that determine the severity of the disease. Biologics have been proven to be effective for some type 2 high patients. Multi-omics approaches, including genomics, transcriptomics, proteomics, metabolomics, and metagenomics, have identified many novel genes or molecules that could serve as biomarkers or potential therapeutic targets for SA. Investigations of the mechanisms of novel genes and molecules will help us understand the condition and find new treatment means for SA in the future.

In this research, we have proposed and investigated a time-delayed free boundary problem concerning tumor growth in the presence of almost periodic nutrient supply with angiogenesis. This study primarily focused on examining the impact of almost periodic nutrient supply, angiogenesis, and time delay on tumor growth dynamics. We analyzed the existence, uniqueness, and exponential stability of almost periodic solutions. Furthermore, we established conditions for the disappearance of almost periodic oscillations in tumors. The existence and uniqueness of almost periodic solutions were proven, while sufficient conditions for the exponential stability of the unique solution were established. Finally, computer simulations were employed to illustrate our results.

O Lugar das Questões de Género no Programa de Governo dos Partidos Maioritários: As eleições de 2022 em Angola
Authors: Telo Florita Cuhanga A.
Published: April 2024

O artigo visa entender até que ponto as questões de género são (des)consideradas no exercício da política ativa em Angola, analisando o programa de governo dos dois maiores partidos políticos (UNITA e MPLA), apresentados nas eleições de 2022. Igualmente, pretende-se compreender a natureza das categorias e conceitos operacionalizados pelos dois partidos políticos, e as suas implicações na mudança ou manutenção das relações de género. Trata-se de um estudo qualitativo exploratório, de cariz bibliográfico e documental. Este artigo conclui que, embora as questões de género tenham um lugar na proposta dos dois partidos políticos, ambas padecem de deficiências conceptuais estruturantes, que comprometem a efetivação da dignidade e dos direitos humanos para todas as pessoas, bem como para a consolidação do Estado, que constitucionalmente, é democrático e de direito.
D’un « je décris » à un « jeu d’écrits ». À propos de la transmission des pratiques de la pédagogie institutionnelle
Authors: Benasé-Rebeyrol Sandrine
Published: April 2024

L’observation d’une séance d’un cours de licence, sur et avec les outils de la pédagogie institutionnelle, a fait l’objet d’un compte-rendu écrit. Sa rédaction a fait émerger deux séries de questions. En premier lieu : comment décrire ce qui a été observé et vécu ? Comment décrire l’inobservable ? J’y ai répondu par le choix d’une forme d’écriture, permettant de faire des allers-retours entre l’observé et les textes fondateurs de la pédagogie institutionnelle, afin de rendre compte, par un jeu de miroir, de la modalité d’enseignement choisie. En second lieu : dans quelle mesure cette pratique de la pédagogie institutionnelle, utilisée dans un contexte différent de celui des textes fondateurs, en est-elle une transposition ? Cette seconde interrogation permet d’élaborer une analyse des processus de transmission et de filiation sous-jacents, fondée sur une approche clinique d’orientation psychanalytique.
L’université entre fonction culturelle et fonction professionnelle avec Habermas, Renaut et Ricœur
Authors: Psomas Sandra
Published: April 2024

Pour penser l’université, l’enjeu de ses fonctions, de ses finalités s’avère essentiel, en soulevant la question de son orientation, de son sens, à l’instar des rôles de l’éducation scolaire, et il se renouvelle dans des réflexions philosophiques contemporaines prenant en considération son évolution. Au sein des débats et controverses, la tension entre fonction culturelle et fonction professionnelle s’avère saillante, comme le montrent les pensées de trois figures, soit Habermas, Renaut et Ricœur. L’université, ayant connu des transformations notamment avec la massification et l’élargissement de la professionnalisation, doit-elle détenir un rôle essentiellement voire exclusivement professionnel ou culturel ? Doit-elle articuler ces deux pôles fonctionnels ? Doit-elle se consacrer à la théorie ou à la technique, à la pratique, ou doit-elle articuler, relier ces dimensions ? Nous verrons en quoi les thèses de Renaut, de Ricœur et de Habermas se rapprochent et se différencient, se singularisent.
Pierre Schoendoerffer, sentinelle et pédagogue
Authors: Roelens Camille
Published: April 2024

Nous proposons ici un abord relevant de la philosophie de l’éducation du thème de la guerre dans l’œuvre du cinéaste Pierre Schoendoerffer. Ses films peuvent être appréhendés comme des œuvres de formation. Lui qui connut la guerre sur le terrain s’attache aussi avec soin à en déconstruire film après film les représentations factices. Montrer la guerre fonctionne alors comme un dispositif pédagogique permettant au spectateur de se former lui-même comme sujet ayant à appréhender sa propre condition historique.

The crucial role of saliva in the prevention of dental caries is associated with the regulation of its flow rate as well as salivary protein. Black tea, derived from the plant Camellia sinensis, contains catechins and has been shown to have a beneficial effect on saliva in preventing tooth decay. Nevertheless, research on the oral health benefits of black tea is still limited. This study aimed to investigate the effects of black tea (Camellia sinensis) on salivary pH (potential hydrogen), salivary flow rate, lysozyme, and sIgA levels in caries and caries-free patients. The study used a quasi-experimental design with a pre-test and a post-test. Twenty six subjects (male or female) were selected and divided into two groups (caries and caries free), thirteen subjects for each. Saliva samples were obtained before and thirty minutes after tea consumption. The flow rate of saliva was measured by dividing the weight of saliva collected by the time. At the same time, secretory immunoglobulin A (sIgA) levels were analyzed by enzyme-linked immunosorbent assay (ELISA). The t-dependent and t-independent tests and Mann-Whitney tests were selected to evaluate the effect of drinking black tea on salivary flow rate and sIgA value. The results showed that black tea significantly increased salivary flow rate but did not significantly affect the concentration of sIgA. No statistically significant differences in salivary flow rate and sIgA were observed between patients with and without caries after tea consumption. Although the concentration of sIgA did not demonstrate a significant change, however, the salivary flow rate was significantly enhanced. Therefore, drinking black tea did not negatively affect the saliva in the oral cavity, suggesting it can be a good option for daily consumption due to its protective role against dental caries.
Influence of Mechanical Properties of Dental Implants on Biomechanical Behavior: A Three-Dimensional Finite Element Analysis
Authors: Goradia Youcef , Gouasmi Sadek , Reffas Sid Ahmed
Published: April 2024

In the context of this numerical study is particularly to analyze and observe the effect of mechanical properties and masticatory efforts on the intensity and distribution of biomechanical stresses induced in the mandibular bone (the cortical bone, the spongy bone) and in the elements which constitute the structure of the dental bridge (abutments, implants, bridge). The 3D model studied is subjected to loading in the three directions of space (corrono-apical, disto-medial, bucolingual). The numerical analysis allowed us to highlight the localization of the stress concentration zones, on the one hand, at the level of the regions of contact between the elements of the dental bridge structure and on the other hand, at the level of the mandibular bone. This parametric approach for the mechanical properties of bridges is used to better visualize and quantify the biomechanical behavior of dental bridges.

Published: April 2024

Slender concrete structures are often assembled from precast segments with concrete joints. Proper functioning of the joints, which are a source of discontinuity in prefabricated structures, is crucial in terms of the overall structure's serviceable life. They are typically cast between segments faces with formwork keys around their perimeter. This contribution compares the results from several numerical analyses of the joints with results obtained from experimental measurements. The analysis results were used in the design of stress ribbon footbridge recently constructed in Tyresta National Park in Sweden.

Ag-specific effector CD4+ T cells play a crucial role in defending against exogenous pathogens. However, the mechanisms governing the differentiation and function of IFN-γ–producing effector CD4+ Th1 cells in immune responses remain largely unknown. In this study, we elucidated the pivotal role of zinc finger protein 335 (Zfp335) in regulating effector Th1 cell differentiation and survival during acute bacterial infection. Mice with Zfp335 knockout in OT-II cells exhibited impaired Ag-specific CD4+ T cell expansion accompanied by a significant reduction in resistance to Listeria infection. Furthermore, Zfp335 deficiency restricted the effector CD4+ Th1 cell population and compromised their survival upon Listeria challenge. The expression of T-bet and IFN-γ was accordingly decreased in Zfp335-deficient Th1 cells. Mechanistically, Zfp335 directly bound to the promoter region of the Lmna gene and regulated its expression. Overexpression of Lmna was able to rescue the survival and function of Zfp335-deficient effector Th1 cells. Therefore, our study provides novel insights into the mechanisms governing effector Th1 cell differentiation and survival during acute infection.
Vero uomo o uomo vero? Quale contributo serve oggi per la prevenzione primaria della violenza di genere e per sostenere la salute mentale di bambini, adolescenti e uomini
Authors: Pellai Alberto
Published: April 2024

Il disagio emotivo e la difficoltà di chiedere aiuto e supporto psicoterapeutico connotano in modo maggiore il genere maschile. I maschi crescono aderendo al modello del ‘vero uomo’, un modello spesso impregnato di stereotipi di genere che impongono di aderire ad un ruolo di genere in cui il vissuto emotivo viene spesso negato o invalidato e la richiesta di aiuto è vissuta come una vulnerabilità individuale e non come una risorsa per affrontare una sfida evolutiva o di vita. Questo lascia spesso i maschi, sia in età evolutiva che adulti, in una condizione di analfabetismo emotivo che può essere prodromico e preparatorio a problemi di rilevanza clinica e sociale, fino allo sconfinamento nella violenza di genere. In questo articolo si affronta il tema del disagio emotivo degli uomini, leggendolo come un fenomeno radicato nel ruolo di genere favorito dal contesto socio-culturale ed evidenziando il ruolo che potrebbe essere rivestito dalla prevenzione primaria e secondaria e dall’intervento educativo in ambito scolastico e comunitario quali facilitatori di cambiamento, evoluzione e promozione del benessere psico-emotivo delle future generazioni.
Commento sull’articolo ‘Per una psicoterapia d’ispirazione sociale’

La lettura dell’articolo è stata molto interessante e ricca di spunti di riflessione. Lo sviluppo e la diffusione di una psicoterapia sociale è un argomento estremamente attuale, soprattutto analizzando nel dettaglio il contesto socioculturale attuale. Trovo molto interessante la divisione nelle quattro macrocategorie e penso che possa essere particolarmente utile per il lettore poter leggere qualche riflessione in più da parte dell’autore. [...]
‘Lo zero è un numero però da solo non è niente’: sulla qualità della relazione educativa. Commento al testo ‘Disturbi specifici (della relazione) di apprendimento’
Authors: Negretti Monica
Published: April 2024

Il libro di Gandolfi e Negri ci propone e apre, attraverso il tema dei disturbi specifici di apprendimento e con l’approfondimento sul ‘cosa serve per arrivare alla conquista della scrittura, della lettura e del calcolo’, ad una riflessione più ampia sul tema della ‘qualità’ della relazione educativa. E la qualità ha a che fare con il tipo di investimento che l’adulto ha sui bambini con cui è in interazione. Chi è un bambino? Che rapporto c’è tra insegnamento e apprendimento? Qual è il ruolo dell’adulto? [...]
