Authors: Baranchuk S. , Bortnyk K.
Published: October 2024

У цій статті розглянуто розробку та впровадження системи для моніторингу відключень електроенергії на основі сучасних технологій Інтернету речей (IoT), яка поєднує в собі платформу Arduino та фреймворк React Native. Система складається з чотирьох ключових компонентів: мікроконтролера NodeMCU, який відповідає за збір даних про наявність електроенергії, серверної частини на базі Node.js, яка обробляє запити і керує базою даних, хмарного сервісу Firebase для збереження даних та надання функціоналу push-сповіщень, а також мобільного додатка для Android, який дозволяє користувачам отримувати актуальну інформацію про стан електропостачання. Основний функціонал системи полягає у фіксації часу та місця відключення електроенергії в автоматичному режимі, що забезпечує надійність та своєчасність передачі інформації користувачам через мобільний додаток. Завдяки інтеграції з Firebase, дані зберігаються у хмарі, що дозволяє доступ до них навіть у випадку локальних збоїв інтернет-зв'язку. Також у статті детально описані технічні аспекти розробки, включно з принципами використання необхідного ПЗ та додаткових бібліотек, а також механізми надсилання push-сповіщень через Firebase Cloud Messaging. Особливу увагу приділено використанню сучасних підходів до управління станом React компонентів у мобільному додатку, що дозволяє динамічно оновлювати інтерфейс користувача на основі зміни даних у режимі реального часу. Запропонована система є важливим кроком у розвитку технологій моніторингу електропостачання, а також має перспективи подальших досліджень, зокрема, в напрямку оптимізації споживання енергії пристроями IoT, підвищення безпеки передачі даних та розширення функціоналу

Humans are unable to function without water. Water is therefore necessary for living. This study will address the advantages of converting air into drinkable water based on this premise. Regarding the condensation process itself, it is not the best option to use it in remote locations because it needs a lot of energy and equipment. Consequently, thermoelectric technology was used in this study to replace the condensation process. This tool's easier thermoelectric operation makes it suitable for usage in remote locations. The design of an effective Arduino program control system should take into account the effects of temperature and humidity condition parameters on the environment to maximize water production. This will allow the performance between supporting sensors and the main components to be automatically optimized under a variety of environmental conditions and produce water without wasting excessive energy. As a result, the trial where the average temperature was 30°C and the average humidity was 81% produced the highest results for the researchers when they calculated the environmental condition factors that were already known. Within the hour-long study session, 6 milliliters of water were created. In addition to the efficiency with which the Arduino program is commanded, from all sensors to the primary thermoelectric components, it can execute commands automatically and optimally. It can also resolve issues that affect the air-to-water converter controller's performance in a way that ensures proper operation of all controllers by taking into account the relevant factors. to the fullest without squandering too much energy
Cylinder segment mount modification to reduce cylinder segment downtime problems on curing machines
Authors: Yusuf Nugroho  , Subekti Subekti
Published: October 2024

In tire manufacturing companies in Indonesia, there is a tire production process consisting of material, building, curing, and final inspection. The curing process is the process of changing green tires into tires which takes place in a mold segment at temperature and pressure according to predetermined specifications. On the BOM 63.5 curing press machine there is a segmented cylinder that functions to press the mold segment. The problem that often occurs in curing machines is that the segment cylinder breaks. This causes quite high machine downtime. The number of cylinder segment bolt holes influences the strength of the bolt connection. Therefore, it is necessary to modify the cylinder segment bolt-hole holder so that the bolt can support the cylinder load. The results of this modification can reduce curing machine downtime problems and can increase company productivity. Based on the results of this research, it can be concluded that 6 bolts are safer than 4 bolts. The downtime problem of the cylinder segment after modification decreased by 94%. The previous one was 15181.18 minutes to 1038.11 minutes

Every company, including PT, has goals they'd like to accomplish. One of the businesses in the two-piece can sector is CPC. Up until now, PT's goal has been to switch products. The CPC is still not fulfilled; specifically, from January 2022 to May 2023, the product replacement time is still 42 minutes, resulting in the waste of 1043 cans, although the objective was set at 30 minutes for the replacement of the product and 800 cans for spoiling (wasted cans). The current issue is that 800 cans are wasted, and the goal product replacement time is 30 minutes. A quality control group was employed in this study's methodology (Pareto and fishbone diagrams). The primary goal of this study is to identify the underlying cause of the 42-minute product replacement time and the wasted 1043 cans. The analysis's findings demonstrated that the issue of resetting the plate is the one that frequently arises while switching out products. Several underlying causes of the reset plate issue were discovered after additional investigation, one of which was the unclear marking on the plate, which led to imprecise results when the plate was installed on the cylinder. Damages the can printing and necessitates a second plate installation, which wastes time and leads to spoilage. Consequently, a repair plan was created and put into action by changing the plate's markings to make installation easier to understand. This led to a quicker process of replacing the product (41 minutes before repair, 32 minutes after repair), as well as a decrease in the number of wasted cans (850 cans before repair, 828 cans after repair).

Reflexiones y tendencias de la Teoría de la Educación y su aportación a la formación del profesorado
Authors: Vergara Montserrat Vargas
Published: October 2024

En el contexto actual, donde la educación afronta desafíos cada vez más complejos, la Teoría de la Educación cobra especial relevancia. Este trabajo presenta una reflexión crítica sobre la contribución de esta disciplina a la pedagogía y al diseño de políticas educativas y planes de estudio que orienten la formación de la ciudadanía. Se parte de un esquema general propuesto para comprender el proceso resultante tras los cambios sociales, y cómo estos influyen y determinan la educación, destacando la Teoría de la Educación como ciencia que analiza, propone y diseña procesos educativos en todos sus niveles y dimensiones. Los retos socioeducativos abordados en este trabajo resultan de la lectura crítica y reflexiva de las publicaciones del Seminario Interuniversitario de Teoría de la Educación (Salamanca 2022 y Baeza 2023), referente importante en el ámbito educativo.
Finalmente, se presenta una estrategia pedagógica en torno al uso de la inteligencia artificial en una asignatura del grado de Educación Infantil. Se concluye en que la Teoría de la Educación es una ciencia necesaria, cuya exclusión de los planes de estudio privaría a los futuros docentes de un marco conceptual sólido que oriente su práctica educativa hacia las demandas de la sociedad actual.

Published: October 2024

A formação inicial de professores constitui-se temática de estudos e pesquisas e caracteriza-se como um momento privilegiado para os futuros professores e contribui fortemente para ampliar os saberes e conhecimentos necessários ao exercício da profissão docente. Nesta perspectiva, o alerta sobre o apagão docente ressurge: há carência de professores no Brasil para lecionar na Educação Básica. Neste sentido, o problema a ser discutido, neste estudo, centra-se em: como se configura a oferta de cursos de licenciatura no Rio Grande do Sul, nas universidades públicas e comunitárias? E nesse mote, como se encontra o curso de Pedagogia? O procedimento metodológico se articula em dois eixos: um de natureza bibliográfica e de análise documental nos sites das Instituições de Ensino Superior (IES) públicas e comunitárias. Este artigo objetiva analisar o panorama de oferta dos cursos de formação inicial de professores, no Estado do Rio Grande do Sul (RS), nas universidades públicas e comunitárias, possibilitando o mapeamento das ausências de oferta, bem como a situação da Pedagogia neste contexto. Os resultados identificam que a instituições precisam buscar melhor inserção na sociedade local e regional, analisando, discutindo e equacionando as diferentes situações vivenciadas. As considerações são indicativas de que a realidade do apagão de professores no RS, também se faz sentir pela ausência de oferta na formação inicial.

Published: October 2024

The direct nucleophilic addition of amides to unfunctionalized alkenes via photoredox catalysis represents a facile approach towards functionalized alkylamides. Unfortunately, the scarce nucleophilicity of amides and competitive side reactions limit the utility of this approach. Herein, we report an intramolecular photoredox cyclization of alkenes with β-lactams in the presence of an acridinium photocatalyst. The approach uses an intramolecular nucleophilic addition of the β-lactam nitrogen atom to the radical cation photogenerated in the linked alkene moiety, followed by hydrogen transfer from the hydrogen atom transfer (HAT) catalyst. This process was used to successfully prepare 2-alkylated clavam derivatives.

A artéria coronária esquerda se divide em dois ramos principais; o ramo interventricular anterior e o ramo circunflexo. Independentemente desse padrão de ramificação típico, outros padrões de ramificação podem ser vistos, sendo estes ramos suplementares comumente conhecidos como ramos intermédios. Dessa forma, o presente estudo tem como finalidade relatar um caso de trifurcação da artéria coronária esquerda. Este fato foi observado durante uma dissecção de rotina em um coração pertencente ao laboratório de anatomia humana da UEA. Após exposição dos vasos coronários observou-se a trifurcação da coronária esquerda e para posterior análise foi realizada a morfometria do ramo intermédio através de um paquímetro digital, tendo assim as medidas de 1,8 mm de diâmetro, 39,2 mm de comprimento e originando-se a cerca de 14,2 mm de distância da origem da ACE. Embora a bifurcação seja o padrão mais prevalente de ramificação da artéria coronária esquerda, a presença de um ramo intermédio, embora menos comum, evidencia a complexidade e diversidade anatômica dessas estruturas. A literatura indica que, apesar de geralmente não provocarem efeitos hemodinâmicos adversos, variações como o ramo intermediário podem, em certos casos, estar associadas a um risco aumentado de aterosclerose e eventos isquêmicos.

Authors: Noriega-Aguirre Lorena Itzel , Ríos María Fernanda
Published: October 2024

Introduction: Infection by SARS-CoV-2 affects multiple organs, but the lung is the most affected organ and can have sequelae. The diagnosis of sequelae includes: medical history, physical examination, chest radiography and/or tomography, and pulmonary function tests (spirometry, carbon monoxide diffusing capacity, 6-minute walk test, and lung volumes). The objective of this study was to describe lung function in post COVID-19 patients at the Center for Diagnosis and Treatment of Respiratory Diseases CEDITER. Methodology: We conducted a descriptive, retrospective, and cross-sectional study of patients over 18 years of age, with a history of SARS-CoV-2 infection, who had undergone any pulmonary function tests and were found in the CEDITER database, from March 2020 to December 2021. Results: 246 cases were included, of which 57.7% were male and 43.3% were female. The mean age was 50.8 years with a standard deviation of 13.2. 46.1% had a body mass index (BMI) between 30 and 39.9, classified as obesity. 207 spirometries were analyzed, of which 34.3% were abnormal. Out of the 236 carbon monoxide diffusion tests, 53% showed mild to moderate decreases. Conclusions: The pulmonary function test that was most affected was carbon monoxide diffusion (DLCO), in a predominantly male population, with overweight or obesity, and with a mean age of 50 years.

Published: October 2024

Introducción. Al inicio de la pandemia, mientras se conocía más sobre COVID-19, cada país fue implementando medidas preventivas de manera progresiva, ocasionando diferencias en su impacto y cumplimiento. Este estudio pretende evaluar el cumplimiento y factores sociodemográficos asociados a cuatro medidas preventivas no farmacológicas anunciadas en Panamá. Métodos. Estudio transversal realizado entre junio y julio 2020. Se describieron frecuencias absolutas y relativas, se realizó la prueba Chi cuadrado para evaluar asociación y riesgo entre los potenciales factores a través del Odds Ratio (OR), con p < 0.05 como umbral significativo, y la V de Cramer. Resultados: Se incluyeron 3484 participantes. El nivel educativo bajo fue factor de riesgo de incumplimiento de las cuatro medidas preventivas estudiadas. El nivel de ingresos bajo fue factor de riesgo para incumplimiento del uso de mascarilla (OR = 2.0; 95% IC = 1.6-2.5) y lavado de manos (OR = 1.6; 95% IC = 1.3-2.0). Ser masculino fue factor de riesgo para no lavarse las manos (OR = 1.5; 95% IC = 1.3-1.9). Conclusiones: Aunque la mayoría cumplió con las medidas preventivas, el incumplimiento en el uso de mascarillas y lavado de manos, ambos asociados a nivel educativo y de ingresos bajos, se debieron probablemente a falta de educación en salud y dificultad de acceso a mascarillas y agua limpia. Se necesitan estudios en diferentes ámbitos y de mayor complejidad para enfocar las estrategias de prevención a las propias necesidades de cada región y afrontar mejor las próximas epidemias.

Post-Vaccine Myocarditis: Clinical Insights and Epidemiological Trends
Authors: Satya Vani N. Meher
Published: October 2024

Myocarditis is a rare but key adverse event linked to mRNA COVID-19 vaccines, predominantly in young males. Epidemiological data indicate an incidence of approximately 12.6 cases per million doses administered to patients aged 12-39 years, mostly following the second dose of the vaccine. Most patients present with elevated levels of cardiac biomarkers, chest pain, and abnormal ECG findings within a few days of vaccination. Proposed mechanisms for the exact pathophysiology of this include molecular mimicry between the SARS-CoV-2 spike protein and cardiac antigens, activation of immune pathways, and dysregulated cytokine expression. Despite these findings, the overall benefit-risk balance for COVID-19 vaccination remains positive, as the majority of patients recover fully. In contrast, COVID-19-associated myocarditis is more common and more severe, with an estimated incidence of 1,000-1,400 cases per 100,000 infections. Clinical presentation of vaccine-associated myocarditis is usually mild and self-limiting, and most patients do recover without significant long-term effects. Treatment is usually supportive in nature and has an emphasis on ruling out acute coronary syndrome and symptomatic management for heart failure or arrhythmias if present. Given its low incidence and the generally good outcome, vaccination against COVID-19 is recommended from 12 years of age and above, with provision for ongoing surveillance for monitoring and management of rare adverse events like myocarditis.

Authors: Rasedile Tumelo
Published: October 2024

Entrepreneurship education has become increasingly important worldwide, including for graduates in South Africa. Like their counterparts in other emerging economies, South African graduates face challenges in starting their businesses. This study focused on Graphic Design graduates at the Tshwane University of Technology (TUT), who encountered difficulties in establishing their design businesses. The research aimed to develop an entrepreneurship education framework for the Integrated Communication Design (ICD) programme at Tshwane University of Technology. A qualitative method was used along with an interpretivism research philosophy to examine small and micrographic design businesses in Tshwane’s central business district. In this article, twelve participants were chosen through purposive sampling. Four main themes were revealed in this article namely, core entrepreneurial skills, curriculum challenges in practical education, challenges faced by graphic design graduates, and strategies for improving business performance. These findings informed the proposed framework for entrepreneurial education for Tshwane University of Technology. The study identified ten key challenges for graphic design graduates, such as a lack of contracts, mentorship, and financial support, difficulties in hiring skilled staff, limited business knowledge, reliance on government contracts, excessive subcontracting, brand recognition issues, cash flow problems, and corruption. The study concluded by emphasising the urgent need for a shift in graphic design education, particularly in South Africa. It is recommended that graphic design educational institutions and the government join hands in finding ways to sponsor these entrepreneurs financially and non-financially to make their transition into the corporate world as smooth as possible.

Authors: Saadi Amina , Bakhouche Badis , Djemadi Imad , Beladjal Lynda , Kherbouche-Abrous Ourida
Published: October 2024

Cedrus atlantica, a species of coniferous tree in the Pinaceae family, is endemic to Algeria and Morocco. It originated in the Atlas Mountains of North Africa, hence the name Atlas Cedar. Cedar forests are home to a diverse range of flora and fauna. Yet despite their importance as a rich reservoir of fauna, very few faunistic studies have been carried out in Algeria in this type of ecosystem, particularly for the Araneae. Théniet El Had National Park (34.25 km2) is a unique national park in the western part of Algeria with centuries-old cedars. The present work is the first of its kind, consisting of establishing a preliminary list of Lyniphiidae in this typical ecosystem.

A preliminary checklist of Linyphiidae of the National Park is provided, following a sampling period between January and December 2019. A total of 24 species were collected belonging to 15 genera of which Pelecopsis is the richest genus with six species. Pelecopsis oujda Bosmans & Abrous, 1992 and Walckenaeria heimbergi Bosmans, 2007, only known from Morocco so far, were collected for the first time in Algeria. Their distribution area is, thus, more extensive than present.

Authors: Estrada Jeremaiah , Canonigo Claudette , Gentallan Jr. Renerio
Published: October 2024

Cynometra cebuensis F. Seid. is an endemic and threatened tree from the Philippines. The species was previously described to exclusively thrive in the Tabunan Forest of the Central Cebu Protected Landscape. Due to its narrow geographic distribution and threats from land conversion, slash-and-burn activities and non-regulated wood harvesting by locals, C. cebuensis was assessed as Critically Endangered (CR) under criteria B1a and B1b (as well as B2a and B2b) of the IUCN Red List in 2013. The present study provides new additional locations of C. cebuensis in the Municipalities of Argao and Minglanilla in Cebu along with population data and habitat characteristics for each site. Although new populations of C. cebuensis were discovered, it remains at significant risk of extinction in its natural habitat. Urgent and comprehensive conservation efforts are imperative to prevent its extinction.

This paper provides the updated distribution map of Cynometra cebuensis F. Seid, a critically endangered endemic species in the Philippines showing five (5) distribution records.
Work-life Balance of White-collar Remote Workers in a Technopark in Turkey
Authors: Eşici Hasan , Şehitoğlu Yasin , Ayaz Ahmet , Karaman Mehmet Akif
Published: October 2024

The main purpose of the current study was to explore the work-life balance experiences of white-collar employees who shifted to remote work in a Technopark in Turkey during the COVID-19 pandemic, using a phenomenological approach. The research was conducted in two phases. In the first phase, 49 white-collar workers participated by completing online questionnaires to assess their work-life balance. In the second phase, two focus group discussions were held, involving 11 participants. The data gathered from the questionnaires and focus groups were analyzed using interpretive content analysis method with MAXQDA 20 software.

The content analysis revealed that personal factors, such as personality traits and adaptability, influenced the work-life balance of the white-collar employees. Among organizational factors, workplace culture and the home environment emerged as significant determinants. Most remote workers were found to be unable to set a work-life balance, consequently experiencing conflicts. However, some participants managed to maintain a harmonious balance between their professional and personal lives, though it tended to be skewed towards a work-centered equilibrium. The observed imbalances resulted in several negative outcomes for the participants, including the need for psychological support, role conflicts in different aspects of life, and diminished motivation. In contrast, those who achieved balance reported higher levels of life satisfaction, job satisfaction, and subjective well-being.
The Significance of Intracellular Versus Extracellular Calcium Pyrophosphate Crystals in Diagnosing Calcium Pyrophosphate Crystal Arthritis
Authors: Harris David J. , White Douglas H.N. , Arad Uri M.
Published: October 2024

Objective

Acute and chronic calcium pyrophosphate (CPP) crystal arthritis is characterized by the presence of synovial CPP crystals within a clinically inflamed joint. CPP crystals may be situated intracellularly or extracellularly; however, the clinical significance of their location remains understudied. The objective of this retrospective cohort study was to assess the relevance of the CPP crystal location in diagnosing acute/chronic CPP crystal arthritis.

Methods

Data were collected from Waikato District Health Board to identify a study population with synovial fluid samples positive for CPP crystals. The cohort was stratified into 2 groups based on crystal location: intracellular and extracellular. The proportions of acute/chronic CPP crystal arthritis cases were compared between these groups. Acute/chronic CPP crystal arthritis was diagnosed when synovial CPP crystals were present, with objective evidence of joint inflammation and no other alternative diagnosis. Further analysis was made with respect to demographics, other laboratory results, and cartilage calcification.

Results

This study included 134 patients: 108 with intracellular CPP crystals and 26 with extracellular CPP crystals. Acute/chronic CPP crystal arthritis was diagnosed in 85% of cases in the intracellular and 50% in the extracellular group (P< 0.001). Following exclusion of septic arthritis cases, acute/chronic CPP crystal arthritis was diagnosed in 97% of patients in the intracellular group and in 62% of those in the extracellular group (P< 0.001).

Conclusion

The presence of intracellular CPP crystals is more strongly associated with acute/chronic CPP crystal arthritis than with extracellular CPP crystals alone.

Références nationales et européennes dans la campagne européenne de six partis français et allemands
Authors: Dubslaff Étienne , Knopper Françoise
Published: October 2024

Les partis proeuropéens que sont la CDU-CSU, LR, le SPD ou encore le PS cherchent à trouver un juste équilibre entre les politiques sociales des États et la défense des intérêts sociaux communs aux Européens. Afin d’accomplir cela, ils utilisent des catégories qui font consensus parmi les Européens de la même famille politique, mais qui découlent en réalité des histoires respectives, qu’elles soient syndicales, constitutionnelles ou sociales. Les programmes demeurent marqués par les cultures politiques nationales. Les politiques sociales sont donc multiples, comme en témoignent les priorités qui distinguent les grands groupes politiques du Parlement en fonction de leurs idéologies ou à l’intérieur des groupes eux-mêmes. Quant aux partis souverainistes, le RN et l’AfD n’ont guère d’intérêt pour la politique sociale et ne l’évoquent que pour en présenter les bienfaits comme menacés par l’Europe et les étrangers – européens comme extra-communautaires.
Comparaison et bouleversement des modèles économico-sociaux en RFA et RDA autour de 1990
Authors: Bouiller Sophie
Published: October 2024

Cette contribution propose, à partir de l’exemple de l’assurance retraite et de l’assurance chômage, une comparaison entre la politique sociale des deux Allemagnes à la fin des années 1980 et une analyse des répercussions de l’unité allemande sur le système de protection sociale. Les différences idéologiques majeures dans la conception même de l’État-providence permettent dans un premier temps de mettre en lumière les spécificités d’un modèle social démocratique et paritaire en RFA par opposition à un modèle social autoritaire et unifié dans un État dictatorial comme la RDA. L’ouverture du Mur puis le processus d’unification en 1989-1990 ne firent ensuite qu’accentuer les dysfonctionnements d’un État-providence déjà en proie à une crise profonde depuis le milieu des années 1970. Aux débats sur le financement et donc la pérennité du système de protection sociale s’ajouta la question des inégalités de traitement entre Allemands de l’Ouest et de l’Est lorsque fut négociée l’unité sociale entre les deux États. Si des acquis sociaux est-allemands purent être conservés temporairement, ils ne donnèrent pas pour autant lieu à une refondation de l’État-providence dans l’Allemagne unifiée. Bien au contraire, le système de protection sociale ouest-allemand fut étendu à l’Allemagne de l’Est et les coûts de l’unité sociale, comme de l’unité allemande, pesèrent encore plus lourdement sur les finances fédérales dans la première moitié des années 1990.
Développements et référentiels pour les droits sociaux à l’échelle européenne
Authors: Müller-Graff Peter-Christian
Published: October 2024

L´ensemble des réflexions menées dans cet article montre qu’il serait erroné d’affirmer que le droit social et la politique sociale de l’Union européenne ne favorisent pas la convergence social dans l’Union sur le plan juridique. On y trouve des compétences constitutionnelles de l’Union européenne : à promouvoir l’uniformisation du curriculum des travailleurs migrants dans le droit social ; à éliminer d’éventuelles barrières nationales à l’accès à l’emploi et des distorsions de concurrence qui pourraient résulter des différents coûts du droit social dans les États membres (par voie de son rapprochement dans l’intérêt du fonctionnement du marché intérieur) ; ainsi qu’à soutentir et compléter l’action des États membres dans des domaines spécifiques de la politique sociale. On y trouve également une multitude de législations pertinentes de l’Union. Cependant, on ne sait toujours pas clairement dans quelle mesure la jurisprudence fondée sur les droits sociaux de la Charte des droits fontamentaux peut contribuer au développement de la convergence sociale dans l’Union européenne.
Dilemmes éthiques en terrains militants radicaux
Authors: Rasulo Margherita , Pietron Florian
Published: October 2024

Cette contribution vise à analyser les enjeux éthiques liés aux recherches en terrains militants radicaux à travers une comparaison entre deux cas d’étude méditerranéens : l’organisation de gauche radicale italienne Potere al popolo ! (« Pouvoir au peuple ! ») dans le Mezzogiorno (moitié sud de l’Italie) et les formes de militantisme culturel-identitaire et féminin en Kabylie (Algérie). Nous développons un dialogue avec la littérature internationale et analysons les enjeux éthiques inhérents à chaque étape du processus de recherche. Posture épistémologique, pratiques ethnographiques et restitution/valorisation des résultats font ainsi l’objet d’une réflexion appuyée par les matériaux empiriques mobilisés. Nous défendons une approche éthique réflexive car les principes faisant l’objet d’un consensus au sein de la discipline sociologique se traduisent par des applications pratiques inégales et négociées en fonction des conditions et des configurations de la recherche. Nous reconstruisons les processus qui ont conduit aux choix adoptés dans les différents cas présentés afin de répondre aux injonctions paradoxales entre valorisation des résultats et minimisation des risques.
Les études de la gouvernance d’internet à l’épreuve des terrains sensibles
Authors: Musiani Francesca
Published: October 2024

L’article discute les défis d’éthique de la recherche auxquels est confrontée une sociologie qualitative sur deux terrains sensibles – le développement et les usages de messageries chiffrées dans des contextes à haut risque, et les stratégies de contournement de l’autoritarisme déployées par les acteurs techniques de l’Internet russe. L’article aborde notamment trois aspects : il reflète les défis rencontrés dans le travail empirique et théorique ainsi que les considérations et décisions prises en réponse à ces défis ; il détaille et justifie les engagements pris envers nos sujets de recherche, et les insère dans un dialogue ouvert sur la relation entre chercheurs et informateurs ; il contribue enfin à un débat sur l’éthique de la recherche dans le domaine de l’activisme et de la participation médiés par le numérique, son positionnement et ses conséquences.
Partage des données et protection de la confidentialité : quels nouveaux enjeux pour les sciences sociales ?
Authors: Silberman Roxane
Published: October 2024

Cet article examine comment le partage des données pour la recherche, une question apparue dans le domaine des sciences politiques avec le mouvement du data sharing dans l’immédiat après-guerre, interroge la déontologie et l’éthique des sciences sociales à l’aune de trois aspects importants du paysage contemporain : 1) un processus d’institutionnalisation de cette question du partage des données et une exigence croissante de rendre les résultats des travaux reproductibles ; 2) la question de la confidentialité et l’anonymisation des données qui devient centrale – les procédures et les nouveaux dispositifs sécurisés mis en place pour répondre aux dispositions du corpus législatif et réglementaire en matière de traitement de données confidentielles pour la recherche ouvrent de nouvelles possibilités mais suscitent nombre d’interrogations voire d’incompréhensions ; 3) l’explosion du nombre de données disponibles et les nouvelles possibilités de traitement remettent aussi en question le modèle d’organisation des Data Archives, héritier de la naissance du data sharing, au moment même où elles se voient reconnues par l’institutionnalisation du partage des données pour la recherche.
Élections après élections : la résistible ascension de l’extrême droite dans le mouvement syndical
Authors: Guillas-Cavan Kevin
Published: October 2024

En septembre, le parti d’extrême droite Freiheitliche Partei Österreichs (FPÖ) pourrait accéder à la chancellerie. Les récentes élections des chambres des travailleurs sont alors vues comme des tests. L’extrême droite y fait désormais jeu égal avec la démocratie chrétienne. Si elle peine à s’implanter dans le syndicat, l’adhésion syndicale ne protège cependant plus du vote à l’extrême droite. Son retour au pouvoir pourrait alors menacer l’existence même des chambres des travailleurs, qui constituent le coeur du pouvoir syndical.
La collaboration en situations d’intermétiers à l’épreuve des obstacles contextuels
Authors: Benoit Hervé , Chesnay Julie
Published: October 2024

Alors que la collaboration entre des acteurs relevant d’univers professionnels différents et participant à la scolarisation des élèves en situation de handicap est promue par les textes institutionnels et semble être une condition à la mise en œuvre de dispositifs inclusifs, son effectivité peine à se réaliser dans les établissements scolaires. Dans cette dynamique, le terme d’ intermétiers correspond à la nécessité de créer un espace se situant à l’intersection de professions et d’expertises différentes, espace permettant la construction dialoguée de réponses pédagogiques et éducatives adaptées aux besoins des élèves. Il s’agit ici d’identifier et de produire des premiers éléments de compréhension liés au travail collaboratif dans une visée inclusive à partir de dispositifs dédiés mis en place par l’institution.
Vers une éthique en formation interprofessionnelle pour transcender les différences de métier entre enseignants et professionnels du médico-social
Authors: Khamzina Kamilla , Kheroufi-Andriot Olivier , Rossi Sandrine , Cilia Federica , Brasselet Célénie , Legrain Camille , Guirimand Nicolas , Desombre Caroline
Published: October 2024

Les résultats d’une enquête exploratoire alimentent une réflexion autour de formations interprofessionnelles en matière d’éducation inclusive entre enseignants et professionnels du secteur médico-social. L’hypothèse posée est qu’une dimension éthique permet de transcender les différences de métier au bénéfice de pratiques éducatives des uns et des autres plus inclusives. Cette enquête exploratoire repose sur la réalisation d’une trentaine d’entretiens semi-directifs, et mobilise le cadre conceptuel de la clinique de l’activité en psychologie du travail. Après avoir exposé les résultats, une discussion est engagée sur les possibilités et les conditions de mobilisation d’une dimension éthique en vue de construire de telles formations au bénéfice de tous les élèves. Une proposition clôt cet article.
Nouvelles formes de professionnalités inclusives : cas de l’enseignant spécialisé
Authors: Dicharry-Pomarez Sandrine
Published: October 2024

Face aux injonctions de l’éducation inclusive, l’enseignant est pris dans un processus de formation tout au long de la vie. Ce nouvel enjeu conduit au questionnement et au développement de postures professionnelles. Nous avons interrogé le développement de nouvelles formes de professionnalités de l’enseignant spécialisé en partant de l’hypothèse d’une posture de praticien/ chercheur. En nous appuyant sur une conception de la réflexivité menée au quotidien, nous avons choisi les différents outils afin de permettre l’explicitation, d’une part à l’oral (entretien) et d’autre part à l’écrit (questionnaire) de la pratique professionnelle. Le protocole retenu est structuré en trois étapes dans le modèle des recherches compréhensives. Les résultats montrent que l’enseignant spécialisé développe une professionnalité dynamique dans des situations inédites permettant d’entrevoir le caractère indissociable entre recherche/formation et processus inclusifs.
Apprendre à coopérer en EPS, une visée inclusive au service de l’égalité filles - garçons
Authors: Legrain Pascal , Le Briquer Yannick , Lafont Lucile
Published: October 2024

Cet article porte sur l’examen d’un dispositif d’Enseignement par situation complexe (ESC) basé sur les principes de l’Apprentissage coopératif (AC) durant une séquence d’enseignement de douze séances en natation de vitesse au collège. Cette démarche d’enseignement répond au double objectif de l’éducation inclusive, celui de favoriser pour les filles comme les garçons, les acquisitions disciplinaires et le développement d’attitudes soutenant des relations sociales positives entre élèves différents. Les effets du dispositif sur l’évolution des performances chronométriques et motrices, d’une part, et des scores de cohésion, d’autre part, ont été mesurés. Les résultats montrent que le dispositif d’ESC a favorisé la réussite des élèves placés en situation de coopération et en particulier des filles comparativement aux résultats des élèves placés en condition de travail individuel.
