Published: March 2024

RESUMOO atendimento discriminatório e desigual à comunidade LGBTQIA+ tem sido um assunto importante de discussão, apesar de avanços na conscientização sobre minorias sexuais. No entanto, ainda persistem desafios ao lidar com essa população nas salas de emergência, comprometendo o atendimento adequado às suas necessidades de saúde. O objetivo deste estudo foi analisar a disparidade no atendimento emergencial às minorias sexuais, incluindo atrasos no primeiro eletrocardiograma para pacientes com dor torácica, uso diferenciado de tratamentos invasivos e não invasivos, cuidados intra-hospitalares e outras variáveis, e como isso afeta o diagnóstico, atendimento e prognóstico dos pacientes LGBTQIA+. Utilizou-se apenas artigos de ensaios clínicos, estudos de prevalência, estudos de coorte, caso controle e pesquisas qualitativas, que abordassem os descritores pesquisados em literaturas dos últimos 5 anos (2019 a 2023). Com base nos critérios de inclusão e exclusão adotados para o estudo, 10 artigos foram selecionados para análise. Os resultados revelam que questões estruturais impactam negativamente a saúde e o bem-estar desses pacientes, especialmente no ambiente de emergência. Além disso, a comunidade LGBTQIA+ enfrenta dificuldades e receios ao buscar auxílio médico, levando muitos a evitar os serviços de emergência. Esse estudo de revisão amplia o conhecimento sobre o tema abordado e mostra a necessidade de treinar corretamente os profissionais do pronto-socorro para promover um ambiente de prática que garanta cuidados adequados aos pacientes LGBTQIA+. Mostra-se necessário melhorar as interações sociais entre profissionais de saúde e pacientes LGBTQIA+ por meio de intervenções educacionais, a fim de fornecer um atendimento igualitário e adequado às suas necessidades.
MODERNIZAÇÃO DO PODER JUDICIÁRIO: DESAFIOS E PERSPECTIVAS SOB O VIÉS DA PROTEÇÃO DE DADOS PESSOAIS
Authors: Gomes Lidiani Fadel Bueno
Published: March 2024

O presente trabalho investiga a crescente modernização do Poder Judiciário Brasileiro e sua interseção com o direito fundamental à proteção de dados pessoais. A justificativa para esta pesquisa reside na observação de que, enquanto a digitalização oferece vantagens significativas em termos de eficiência e acessibilidade, ela também levanta questões críticas sobre a segurança e privacidade dos dados pessoais dos indivíduos envolvidos em processos judiciais.A problemática central deste estudo concentra-se em investigar a coexistência entre a necessidade de modernização do Poder Judiciário Brasileiro e a obrigação de proteger os dados pessoais dos indivíduos, em um contexto em que a modernização tecnológica e a segurança da informação se apresentam como fundamentais para o Estado Democrático de Direito.A hipótese que norteia a pesquisa sugere que, apesar dos avanços tecnológicos implementados pelo Judiciário brasileiro, ainda existem lacunas significativas em relação à proteção de dados, o que pode comprometer direitos fundamentais dos cidadãos.Para analisar esta questão, em primeiro lugar, a pesquisa se debruçará sobre a evolução da modernização do Judiciário brasileiro, destacando os principais sistemas e plataformas utilizados. Em segundo lugar, abordará a questão da legislação vigente sobre proteção de dados no Brasil, especialmente a Lei Geral de Proteção de Dados Pessoais e sua aplicabilidade no contexto Judiciário e os riscos associados à gestão de dados pessoais nos sistemas judiciais, abrangendo desde o armazenamento até o compartilhamento de informações.Dessa forma, o trabalho desenvolve-se sob o método dedutivo e sob o tipo de pesquisa exploratória, de natureza bibliográfica.

Published: March 2024

O presente estudo teve como objetivo apresentar uma revisão sistemática sobre experiências de criação de animais com vistas a identificar a viabilidade da produção animal em agricultura urbana e periurbana como instrumento de segurança alimentar, observando suas limitações e potencialidades. Foi realizada uma revisão bibliográfica sistemática sobre o tema e a metodologia PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) foi empregada para a seleção dos artigos. A partir da análise de dados emergiu a compressão de que a criação de animais no perímetro urbano e periurbano já existem há centenas de anos e sempre esteve presente em várias cidades do mundo. Essa prática pode representar um desafio inevitável, com aspectos positivos, tais como ser aliada da segurança alimentar doméstica e possibilitar geração de renda e emprego, e também negativos, como presença de odores, ruídos e veiculação de zoonoses. Diante desse conflito, bem como da constatação da viabilidade dessa prática, ressalta-se a importância de políticas públicas capazes de ordenar a atividade, minimizando os riscos sanitários e os possíveis conflitos dela resultantes.

Modular design of the barge platform
Authors: Girin Stanislav N. Girin
Published: March 2024

The paper presents the solution of the problem of creating the design of the barge-platform of the "M-SP 3.5" class of the Russian Classification Society (RCS), intended for manufacturing outside the shipbuilding and ship-repair enterprise on the prepared site near the water body. Hull assembly should be made of separate parts (modules), which are manufactured in the conditions of shipbuilding production and delivered to the place of assembly by automobile or railway transport. Welding should not be used in the assembly process. It is suggested to assemble the barge hull from flat sections of 12,00×2,40 m and fractional sizes; bolted joints should be used during assembly. An example of barge construction of op-determined dimensions is considered. Calculation of the overall strength of the hull assembled from individual sections by means of bolted joints is performed using the ANSYS program complex. It is shown that the strength of the hull and bolts is ensured for the load regulated by the Rules of RCO. The use of bolted joints in forming the hull makes it difficult to ensure its impermeability, in this connection the buoyancy and non-floodability of the barge is proposed to be ensured by means of flexible tanks filled with air. Design and production of such tanks is currently carried out by a number of companies in the Russian Federation.
The history of the soviet innovation of purchase foreign vessels and the prospect of using bareboat charter as way for replenishing the fleet in current circumstances
Authors: Zaretskaya Ekaterina V.
Published: March 2024

The anniversary date, 50 years since the beginning of the grandiose project on chartering foreign vessels with the right to buy them, which became the history of the formation of the shipping company «Sovcomflot», gives an additional reason to consider its details. The analysis of the successful experience of off-budget replenishment of the merchant fleet implemented in the Soviet period is given. It will allow us to come to the conclusion that the financial schemes developed and applied at that time to attract foreign capital through shipping companies specially created in a foreign jurisdiction, acquiring a fleet using tax and other benefits provided for by national legislation for subsequent bareboat charter and compensating for all the expenses by income from   transportation of Russian foreign  trade cargoes, are fully relevant today to replenish the fleet of domestic shipping companies. Also, the advantages of acquiring a merchant fleet using leasing in combination with bareboat charter already considered in the article in modern conditions have shown that this is the optimal mechanism for both preferential leasing and commercial financing schemes. The disadvantage of bareboat charter, which limits its use in modern conditions, is associated with its narrow specialization, both legal and commercial. As appropriate as possible to the traditions and peculiarities of world commercial shipping, it meets the interests of shipping companies, but is little understood by financial institutions. In this regard, it is of particular importance to develop or adapt the available methodological support for assessing the key indicators of the financial scheme for chartering a vessel without a crew (bareboat charter) on the terms of a financial lease (leasing).
The anchorage in cramped travel conditions
Authors: Tokarev Pavel N.
Published: March 2024

It is known that the safety of the anchorage is largely determined by the correct choice of the anchorage location, the depth and type of soil, the dimensions of the water area, protection from wind exposure, the presence of currents in the anchorage. Parking on sea raids in terms of the limited water area does not pose any special problems. In river conditions, the raids are located in close proximity to the ship's passage and are limited in width. Therefore, the question of the width of the strip occupied by the anchored vessel is important. Vessels on the river usually stand on the bow anchor against the current, but quite often, with strong crosswinds, it is necessary to give up the stern anchor in order to reduce the width of the lane occupied by the vessel and not interfere with the movement of passing vessels. The paper presents studies of safe conditions for anchoring ships in river conditions with wind in a limited-sized water area at different flow speeds. Calculated dependences are obtained for determining the transverse size of the water area occupied by a vessel standing at the bow anchor, bow and stern anchors with respect to the axis of the ship's course, depending on the speed of the current, wind speeds and direction.
Elements of technology for processing and disposal of food waste during the operation of ships

Published: March 2024

This article is devoted to the problem of environmental protection by food waste, which is most relevant for water tourism facilities, as well as small and remote settlements. The authors propose, when solving the problem of food waste, to consider the process of their formation, examining the complete process of existence of food products, taking into account their movement in space and transformations, as a result of which waste is formed. This approach allowed us to establish the main stages of this process – preparation for cooking, preparation, and consumption. It is shown that each of them generates waste in different amounts and of different properties. It is also shown that these factors, in turn, determine the most effective technologies and means of processing and recycling food waste. The authors propose, by managing the amount of waste generated, taking into account the quality, to form technologies and means for recycling and disposal of waste. The advantages of this approach are confirmed by examples of ecological solutions that take into account the formation of waste in the process of food transformation, as well as their movement in space, which simultaneously ensures the availability of different solutions to the waste problem for each specific object, including such as water tourism facilities. The availability of different options for solving the waste problem provides the opportunity to choose the most effective solution in the context of organizing a solution to the problem of food waste.

Crime is a significant problem in society, and crime prevention is crucial. Factors such as politics, economics, culture, education, demographics, and employment have been identified as contributing to crime. Recent studies have also explored the relationship between weather and crime. Therefore, this research aims to identify the best-performing machine learning algorithm based on weather in Malaysia, using crime data from the Royal Malaysia Police and Meteorological Department from 2011 to 2020. Five machine learning algorithms were utilized, and the results showed that all algorithms had good prediction accuracy, with Gradient Boosted Trees performing the best, with an error rate of less than 23%. Location was found to be the most important feature in all the models. This study provides a valuable fundamental framework for environmental crime and social impact research scholars to conduct a more in-depth analysis of the prediction models. This study establishes a fundamental framework for scholars in environmental crime and social impact research to conduct in-depth analysis using prediction models, thereby contributing to a better understanding of the complex relationship between weather and crime, and aiding in the development of effective crime prevention strategies.

Published: March 2024

Increasing applications of artificial intelligence in the field of education have changed the way school children learn various concepts. Educational Visual Question Answering or EDUVQA is one such application that allows students to interact directly with images, ask educational questions, and get the correct answer. Two major challenges faced by educational VQA are the lack of availability of domain-specific datasets and often it requires referring to the external knowledge bases to answer open-domain questions. We propose a novel EDUVQA model developed especially for educational purposes and introduce our own EDUVQA dataset. The dataset consists of four categories of images - animals, plants, fruits, and vegetables. The majority of the currently used techniques focus on the extraction of picture and question characteristics in order to discover the joint feature embeddings via multimodal fusion or attention mechanisms. We propose a different method that aims to better utilize the semantic knowledge present in images. Our approach entails building an EDUVQA dataset using educational images, where each data point is made up of an image, a question that corresponds to it, a valid response, and a fact that supports it. The fact is created in the form of  triplet where ‘s’ denotes a subject, ‘v’ a verb, and ‘o’ an object. First, an SVO detector model is trained on EDUVQA dataset capable of predicting the Subject, Verb, and Object present in the image-question pair. Using this  triplet, the most relevant facts from our fact base are extracted. The final answer is predicted using these extracted facts, image, and question attributes. The image features are extricated using pretrained ResNet and question features using a pre-trained BERT model. We have optimized and improved on the current methodologies that use a Relation-based approach and built our SVO-detector model that outperforms current models by 10%.
A Comparative Study on the Performance of Covariance Functions in Gaussian Process Regression model: Application to Global Wheat Price
Authors: Nahamizun Maamor  , Hanita Daud  , Muhammad Naeim Mohd Aris
Published: March 2024

Gaussian Process Regression (GPR) is a nonparametric machine learning model that provides uncertainty quantification in making predictions. GPR utilizes several covariance functions (CFs) in the process of developing models to ensure high accuracy. There are five common CFs in GPR, which are the Radial Basis Function (RBF), Rational Quadratic (RQ), Periodic (Per), Matérn 3/2 (Mat 3/2), and Matérn 5/2 (Mat 5/2), where each covariance function (CF) has different characteristics and behaviors. This paper is to investigate the comparative performances of each CF when applied to the Global Wheat Prices dataset. Error metric measurement like Mean Square Error (MSE) and Root Mean Square Error (RMSE), while Coefficient of Variation (CV) for uncertainty quantification measurement is computed for each CF, and comparisons was made among the CFs to conclude the best CF for this application. The lowest values among them will be the best CF for the data. It should be noted that the CV for each model should be less than 5%, and the CF with the smallest value of CV is considered reliable. The five CFs were fit to the Global Wheat Prices dataset, and it was found that the Mat 3/2 produced the best performances with the lowest values of MSE, RMSE, and CV. Mat 3/2 is the most efficient CF for making predictions since it gives the lowest value of error metric measurement and the lowest value of CV under 5% among the other CFs, making it more reliable for modeling. Overall, the outcome shows that Mat 3/2 is the best CF to be used in developing a GPR model to predict Global Wheat Prices dataset.

Published: March 2024

Estuaries are bodies of water along the coasts that are formed when fresh water from rivers flows into and mixes with salt water from the ocean. The density of seawater is greater than fresh water and it varies with salinity and temperature. Fresh water tends to float on top of seawater because of its lower density. Human-induced activities like the dredging of shipping lanes along the bottom estuarine, the dumping of industrial wastes into the water system, and shoreline development influence estuarine dynamics which include the mixing process. These activities lead to salinity changes and further adversely affect the estuarine ecosystem. The purpose of this research is to verify how salinity-morphology relations change in an estuarine system under various rainfall patterns, more specifically under extremely high rainfall conditions. The experiment that has been conducted studied the salinity-morphology relationships for a variety of rainfall patterns, most particularly for exceptionally high rainfall conditions, using an idealised channel. In the first part of this research, the morphology changes of the mixing between salt water (estuary) and freshwater (river) for different rainfall patterns, had been investigated in laboratory experiments. Fresh water was released from one end of the flume channel and overflowing over the weir at the other end. Meanwhile, salt water was represented by the red dye tracer released slowly through a weir and intruded horizontally to the upstream as a gravity current. In this experiment, an artificial roughened bed section was used as morphology change. The salinity pattern is plotted using Microsoft Excel. The salinity levels were measured at selected stations along the channel/longitudinal (x-axis), and also in transverse (y-axis) and vertical directions (z-axis) within the time duration. The observed salinity profile showed the difference in salinity level between heavy and light rain conditions with morphology effect where during heavy rain, the salinity level will decrease, hence, the existence of an artificial roughened bed section will affect the time taken for the process of mixing between salt water and fresh water.

On the other hand, there is a trend of increasing fraction of galaxies with low Sérsic index at higher redshift, suggesting 3 < z < 5 might be the epoch of onset of morphological transformation with a fraction of very notable disky quenched galaxies.
Spectroscopic Identification and Photochemistry of Astrochemically Relevant Phosphorus-bearing Molecules [O, C, N, P] and [2O, C, N, P]

Published: March 2024

Diatomic molecules phosphorus monoxide (PO) and phosphorus mononitride (PN) are the main reservoirs of gas-phase phosphorus in interstellar and circumstellar environments, indicating the possibility of forming new phosphorus-bearing molecules through reactions with other interstellar species. To explore the astrochemistry of PO and PN, new simple phosphorus-bearing molecules [O, C, N, P] and [2O, C, N, P] were generated in the gas phase and isolated in cryogenic matrices for characterization with matrix-isolation IR and UV/vis spectroscopy in combination with calculations at the CCSD(T)-F12a/VTZ-F12 level of theory. In an inert argon matrix, OPCN isomerizes to OPNC upon UV-light irradiation at 365 nm, followed by successive isomerizations to PNCO and POCN with concomitant dissociation to diatomic PN and CO under further irradiation at 193 nm. By analogy, the isomerization of O2PCN to O2PNC and OPNCO followed by fragmentation to OPN/CO and PN/CO2 occurs in the matrix upon irradiation at 193 nm. In a chemically active CO ice, the photolytic reaction of OPCN with CO yields CO2 and PCN, and O2PCN reacts with CO by forming OPCN and CO2, in which the photochemical networks for these P-bearing species linking the astrochemically important PN and PO have been proposed. The experimental identification of these phosphorus-bearing molecules is supported by quantum chemical calculations, and the spectroscopic data may aid in their detection in the interstellar and circumstellar medium.
Suprathermal Electron Transport in the Solar Wind: Effects of Coulomb Collisions and Whistler Turbulence
Authors: Tang Bofeng , Adhikari Laxman , Zank Gary P. , Che Haihong
Published: March 2024

The nature and radial evolution of solar wind electrons in the suprathermal energy range are studied. A wave–particle interaction tensor and a Fokker–Planck Coulomb collision operator are introduced into the kinetic transport equation describing electron collisions and resonant interactions with whistler waves. The diffusion tensor includes diagonal and off-diagonal terms, and the Coulomb collision operator applies to arbitrary electron velocities describing collisions with both background protons and electrons. The background proton and electron densities and temperatures are based on previous turbulence models that mediate the supersonic solar wind. The electron velocity distribution functions and electron heat flux are calculated. Comparison and analysis of the numerical results with analytical solutions and observations in the near-Sun region are made. The numerical results reproduce well the creation of the sunward electron deficit observed in the near-Sun region. The deficit of the electron velocity distribution function below the core Maxwellian fit at low velocities results from Coulomb collisions, and the excess part above the core Maxwellian fit at high velocities is determined by strong wave–particle interactions.

On the Plasma Quasi-thermal Noise in the Outer Heliosphere
Authors: Meyer-Vernet Nicole , Lecacheux Alain
Published: March 2024

The recent paper by Li et al. on electron quasi-thermal noise (QTN) in the outer heliosphere is flawed. It assumes the plasma drift speed to be much smaller than the electron thermal speed, even though both quantities are of the same order of magnitude in the outer heliosphere inward of the termination shock, because of the low plasma temperature. In this case, the Langmuir wave dispersion equation and the QTN in the antenna frame are completely changed. Furthermore, these calculations neglect the shot noise, which should produce a large contribution below the plasma frequency with the Voyager antennas in the outer heliosphere.
Peculiarities of the exposure dose formation on the population in the most affected regions of Russia after the Chernobyl NPP accident

Published: March 2024

The paper presents an analysis of the current radiation situation in the settlements of the Russian Federation located on the most radioactively contaminated territory after the Chernobyl accident. The assessment of 137Cs content in local agricultural (milk, beef, pork, potatoes), natural (mushrooms) foodstuffs, doses of external, and internal irradiation of residents was carried out. 37 years after the Chernobyl NPP accident, 72 settlements with a total number of residents of 63869 remain in the zone of radioactive contamination whose average effective radiation doses exceed 1 mSv/year. All these settlements are located in five southwestern districts of the Bryansk region and are rural except for Novozybkov. In the private sector of settlements, potatoes and pork fully comply with radiological standards for the content of 137Cs. In milk, the content of the radionuclide can exceed the standards up to 3, in beef up to 5, in mushrooms up to 8–17 times. Over the past 30 years, the number of settlements exceeding the legally established standard for the total exposure dose to the population (1 mSv/year) has decreased by 7.5 times. Due to the decrease in the levels of 137Cs contamination of local foodstuffs and the volume of their consumption, the role of internal exposure dose has been decreasing in recent years. It was noted that in addition to a comprehensive assessment of the radiation situation in settlements, agricultural and natural ecosystems, when planning the rehabilitation of settlements with average annual radiation doses of residents above 1 mSv, it is important to take into account the current diets of residents and the real demographic situation in the territories affected by the Chernobyl accident.

La justice est une des valeurs les plus mises en avant par le sport moderne et la philosophie olympique qui le fonde. Or, cette idée de justice est rarement interrogée ni même conceptualisée, comme si cette notion allait de soi, malgré son ambivalence. L'idéal poursuivi par l'olympisme de Pierre de Coubertin est celui d'une justice aristocratique, où il est considéré comme légitime que les forts dominent les faibles, même si cela n'est qu'au nom d'une supériorité qui pourrait n'être qu'innée, tenant par exemple à de simples prédispositions physiques. Cette conception contrebalance l'idée d'une justice démocratique, laquelle projette au contraire sur le sport l'idée d'un égalitarisme qui voudrait que les hiérarchies ne soient pas fixées a priori, mais fonction des efforts de chacun. Pierre de Coubertin assumait cette tension entre égalité démocratique et inégalité aristocratique, le sport réconciliant selon lui ces contradictions. Toutefois, cette tension entre ces deux types de justice peut conduire à des actes de résistance, comme la triche ou le dopage, cherchant à subvertir l'ordre aristocratique du sport, jugé illégitime. Le sport selon Coubertin reflète ainsi une complexité où justice démocratique et aristocratique coexistent, avec des implications profondes pour la société et ses valeurs.
Le sport. Un système de valeurs au service d'une utopie ?
Authors: Attali Michaël
Published: March 2024

Récurrente dans le domaine du sport, la référence aux valeurs structure les prises de position autant que les initiatives engagées. Considérées comme lui étant consubstantielle, elles conduisent à essentialiser les pratiques comme les comportements. Conceptualisées dès le début de la structuration du mouvement sportif, elles vont se pérenniser et contribuer à sanctuariser le sport. Après avoir caractérisé les valeurs ainsi que leurs fonctions, notre analyse s'attachera à saisir les fondements de leur persistance. Il s'agira alors d'appréhender les conséquences de l'alliage du sport et de certaines valeurs sur les conceptions des acteurs lors des affaires et des interrogations qui secouent le mouvement sportif depuis plusieurs années.
« Ultras » et « hooligans »
Authors: Hourcade Nicolas
Published: March 2024

Depuis les débuts du spectacle du football en Europe, des violences causées par des spectateurs ont toujours émaillé les matches. À partir des années 1960, les violences jusque-là essentiellement spontanées sont devenues principalement préméditées et portées par des groupes de supporters régulièrement violents. Parmi eux, les bandes de hooligans se sont spécialisées dans l'affrontement physique, au point d'organiser des combats arrangés loin des stades, alors que les groupes d'ultras animent les stades tout en usant parfois de la violence pour l'emporter sur les supporters adverses ou faire entendre leurs critiques quant aux transformations en cours du football. Alors que des pays comme l'Angleterre et l'Allemagne ont mis en place dès les années 1990 des politiques globales de gestion des violences et des supporters, la France peine à construire une telle approche, qui pose la question de la bonne conciliation entre les impératifs de sécurité et le respect des libertés individuelles.
Les usages du sport auprès des jeunes sous main de justice
Authors: Le Yondre François , Sempé Gaëlle
Published: March 2024

Les usages des activités sportives par la Protection judiciaire de la jeunesse (PJJ) apparaissent comme des évidences culturelles tant le sport est socialement perçu comme un outil éducatif puissant et vertueux. Si ces représentations sont empiriquement discutables, elles se doublent d'une conception apolitique du sport, y compris lorsqu'il est mis au service d'enjeux incontestablement politiques tels que la délinquance juvénile. Il en résulte un consensus généralisé sur l'intérêt éducatif du sport ainsi qu'une invisibilisation des modèles éducatifs et politiques à l'œuvre dans les usages du sport auprès des mineurs délinquants. L'article met en évidence la manière dont les philosophies éducatives mises en débat dans l'histoire et l'actualité de la PJJ s'actualisent dans ses dispositifs sportifs sans que les professionnels concernés en prennent véritablement conscience. Nous montrons d'une part que le sport, en étant principalement pensé comme un outil de transformation individuelle, s'inscrit dans la tendance générale des politiques comportementalistes consistant à traiter les enjeux politiques et collectifs sous l'angle moral de la responsabilité individuelle. Il suit ainsi une évolution politique qui caractérise plus spécifiquement la justice des mineurs et qui met progressivement à distance le principe de non-responsabilité des mineurs. D'autre part, une ligne de tension émerge dans la place accordée à la logique compétitive. Elle constitue pour certains un modèle social auquel il s'agit de préparer les mineurs délinquants quand elle est, pour d'autres, un contre-modèle éducatif susceptible de renforcer les dispositions agonistiques des mineurs en conflit avec la loi.
La répression des violences sexuelles commises dans le sport
Authors: Richefeu Ludivine
Published: March 2024

La répression des violences sexuelles commises dans le sport est une répression duale qui apparaît plutôt satisfaisante en droit pénal, mais qui pourrait être améliorée en droit disciplinaire, notamment par une meilleure prise en compte de la spécificité de ces violences au sein des textes fédéraux. Duale, cette répression est encore complémentaire ; une complémentarité qui permet de surmonter les difficultés rencontrées par l'une ou l'autre de ces répressions. Ainsi, l'absence de répression pénale en raison de la prescription de l'infraction sexuelle commise par l'entraîneur est compensée par l'imprescriptibilité de l'action disciplinaire. À l'inverse, les difficultés probatoires subies par la procédure disciplinaire sont allégées par l'existence d'une procédure pénale parallèle qui permet à l'organe disciplinaire de mieux fonder sa décision. Une amélioration reste peut-être à apporter pour parfaire cette complémentarité et éviter la contradiction des décisions disciplinaire et pénale, lorsque la première est rendue avant la seconde : l'instauration d'un sursis à statuer obligatoire pour les organes disciplinaires, qui pourrait s'accompagner d'une mesure conservatoire visant à exclure temporairement le mis en cause de l'exercice de ses fonctions au sein de la fédération.
Aux racines de la déjudiciarisation du pénal en Europe : Principes libéraux et « justice parquetière »
Authors: Allinne Jean-Pierre
Published: March 2024

Cet article propose de revenir sur la concurrence en Europe entre le modèle inquisitoire de la procédure pénale, caractéristique des États forts, et un accusatoire plus empreint de souplesse procédurale et mis à la mode par l'anglophilie révolutionnaire. On rappellera combien les lois récentes de « négociation pénale » au profit des parquets rappellent les pratiques vernaculaires de médiation et de conciliation pénales parajudiciaires qui assurèrent jusqu'aux années 1850 l'essentiel de la régulation sociale.
Le pantin algorithmique, ou l'omniabsence du justiciable face à la numérisation de la justice
Authors: Bordere Camille
Published: March 2024

Si la figure du justiciable est une figure habituelle du discours doctrinal français, elle fait l'objet d'une mobilisation particulière au sein d'une thématique elle-même particulière : la numérisation de la justice. Alors même qu'il n'est qu'une cible indirecte de la plupart des objets étudiés dans le cadre de cette thématique, il n'en apparaît pas moins fréquemment convoqué au renfort des analyses menées. Jouant tour à tour le rôle d'outil rhétorique et de prétexte commode, le justiciable apparaît finalement, face à une numérisation de la justice qui se désintéresse de lui, comme l'éternel omniabsent du discours qui s'attache à son analyse.

Un projet individualisé est réalisé en concertation avec celle-ci, et réévalué régulièrement. Au fur et à mesure de cette prise en soins, une orientation est discutée pour accompagner l’enfant vers le suivi le plus adapté à ses besoins à l’issue du camsp .
Surdité et cognition : des recherches à la pratique
Authors: Clouard Chantal
Published: March 2024

Les recherches récentes, à l’intersection de la psychologie développementale et des neurosciences, se sont portées sur les processus cognitifs spécifiques induits par la surdité. La génétique, les travaux sur la pensée visuelle et les fondements des langues des signes ont apporté de nouveaux modèles descriptifs du développement et des apprentissages. Nous étudions certaines de ces avancées et leur influence pour l’examen psychologique et neuropsychologique de l’enfant sourd, pour les remédiations et la pédagogie.

Les troubles du neurodéveloppement ( tnd ) sont plus fréquents en population sourde congénitale. Afin d’appliquer aux bébés sourds les découvertes récentes sur les signes précoces des tnd , de proposer des soins préventifs et de poursuivre la recherche dans ce domaine, une consultation précoce d’observation du développement du bébé sourd a vu le jour. Nous présentons l’étude des facteurs de risques médicaux les plus prévalents dans une cohorte de 22 bébés issus de cette consultation, ainsi que deux cas cliniques.
« Tu n’entends pas ce que je vois ! » Le refus comme appel
Authors: Davodeau Bertrand
