CORPOS FEMININOS NA PERFORMANCE: POR UMA SUBVERSÃO / Female bodies in performance: for a subversion
Authors: Triles Beatriz Nascimento
Published: September 2021

O presente texto aborda os corpos femininos inseridos na performance artística, levando em consideração uma estética feminista que preza uma subversão da perspectiva de fetichização dos corpos femininos, das violências de gênero e das potências daquelas que se identificam com esses femininos. Os corpos femininos, enquanto corpos marcados social e culturalmente por imposições, marginalizações, estigmatizações etc., ao se tornar ferramentas artísticas da performance, passam a ser, também, um gesto crítico-político criador, uma vez que, por meio de sua estética subversiva, atuam como instrumentos e suportes de criação de novas possibilidades de discurso. Dessarte, é pela análise crítica de alguns trabalhos performáticos das artistas Regina José Galindo e Celeida Tostes que se torna possível trazer essas temáticas à tona neste artigo.Palavras-chave: Corpos femininos; Performance; Subversão. AbstractThe present text discusses about the female bodies inserted in artistic performance, taking into account a feminist aesthetic which values a subversion of the perspective of fetishization of the female bodies, gender violence and of the powers of those who identify with these females. The female bodies, as bodies socially and culturally marked by impositions, marginalizations,  stigmatizations etc., by becoming artistic tools of performance, they also become a creative critical-political gesture, to the extent that, through its subversive aesthetics, act as supporting instruments for the creation of new possibilities of discourse. Thus, it is through of critical analysis of some performative works by artists Regina José Galindo and Celeida Tostes that it will become possible to bring these themes to the fore in this article.Keywords: Female bodies; Performance; Subversion.

With the advent of various vaccines and antimicrobial agents during the 20th century, the control and containment of infectious diseases appeared to be a matter of time. However, studies unveiled the diverse natures of microbes, their lifestyle, and pathogenetic potentials. Since the ground-breaking discovery of the hepatitis B virus (HBV) by Baruch Blumberg and the subsequent development of a vaccine in the early 1980s, the main task of the scientific community has been to develop a proper management strategy for HBV-induced chronic liver diseases. In the early 1980’s, standard interferon (IFN) induced a reduction of HBV DNA levels, followed by the normalization of serum transaminases (alanine aminotransferase, ALT), in some chronic hepatitis B (CHB) patients. However, in the course of time, the limitations of standard IFN became evident, and the search for an alternative began. In the late 1980’s, nucleoside analogs entered the arena of CHB treatment as oral drugs with potent antiviral capacities. At the beginning of the 21st century, insights were developed into the scope and limitations of standard IFN, pegylated-IFN as well as nucleoside analogs for treating CHB. Considering the non-cytopathic nature of the HBV, the presence of covalently closed circular DNA (cccDNA) in the nucleus of the infected hepatocytes and HBV-induced immune-mediated liver damages, a new field of CHB management was initiated by modulating the hosts’ immune system through immune therapy. This review will discuss the nature and design of innovative immune therapy for CHB.
Greek Fish Farming: Measuring Profitability and Efficiency of the Sector at the peak of Economic Crisis
Authors: Mavromatti Athanasia , Kontogeorgos Achilleas , Chatzitheodoridis Fotios
Published: September 2021

Fish farming play important role in providing food and income in many EU countries, either as a stand-alone activity or in association with crop agriculture and livestock rearing. Fish farming is widespread in Greece and differs only with respect to species, production systems and volumes. Moreover, the Greek economic crisis has heavily affected the fish farming sector and challenges the competitiveness of farms. The objective of the current paper is the examination of the profitability and efficiency of the Greek fish farming industry during the most crucial years of Greek economic crisis by measuring firm’s performance using a panel data set of companies. The research is based on financial data of sixty-eight aquaculture firms for the period 2010-2015. The empirical results indicate that firms share of total sales has a positive impact on profitability, while an alternative proxy, the total assets is negatively linked to efficiency. Firm's profitability is positively affected by liquidity, working capital management, productivity and industry’s growth and negatively by financial and operating leverage. Firms Efficiency is determined positively by profitability and ability to repay its debt obligations and negatively by capital intensity, operating leverage and size

Se acerca el mayor acontecimiento sobre el que pivota gran parte de la actividad de nuestra Sociedad, el Congreso Anual, que por imperativo sanitario ha de volver a hacerse de forma virtual. Sabemos que este evento es un elemento clave para la difusión de nuestro conocimiento, y resulta fundamental para debatir asuntos de interés, o poner en común diferentes puntos de vista por parte de los asistentes. La COVID-19 ha trastocado los planes de millones de personas en todo el mundo, más allá de las cifras de infectados y fallecidos, el impacto del virus en la vida cotidiana y en la economía está siendo incalculable. Las medidas impuestas por los gobiernos para contener la propagación de la enfermedad motivaron en un primer momento cancelaciones o aplazamientos de eventos por todo el mundo. Pronto se hizo patente que la situación se alargaría y se pusieron en marcha soluciones que minimizaran su impacto. La Junta Permanente de SEDEN reacciono con rapidez y puso su infraestructura y organización al servicio de un proyecto que permitió en un tiempo record organizar un congreso virtual que obtuvo unos excelentes resultados.Se palió el desencanto inicial de no poder reunir a los asociados con la esperanza de que al año siguiente se volvería a la normalidad y mantuvo la cita de Granada para este año.

Authors: Cobacho-Salmoral Olga , Parra-Martos Lucía , Laguna-Castro Marta , Crespo-Montero Rodolfo
Published: September 2021

Introducción: La fragilidad es un síndrome multidimensional caracterizado por una disminución de reservas fisiológicas, de masa corporal magra, debilidad y disminución de resistencia al ejercicio físico. Sitúa a la persona en una situación de mayor vulnerabilidad ante factores externos, además existe una estrecha relación entre la fragilidad y las enfermedades crónicas, como es el caso de la enfermedad renal crónica. Objetivo: El objetivo principal de esta revisión fue sintetizar y conocer la evidencia científica sobre los factores asociados a la fragilidad de los pacientes con enfermedad renal crónica en tratamiento renal sustitutivo en diálisis. Material y Método: Se llevó a cabo una revisión sistemática a través de las bases de datos de Pubmed y Proquest. Se incluyeron artículos originales en inglés y español publicados entre 2015 y 2020, y se analizaron los artículos que trataban sobre fragilidad en el paciente con enfermedad renal en tratamiento sustitutivo. Se excluyeron aquellos artículos que no presentaron resultados. Resultados: Se incluyeron 26 artículos de diseño observacional. Los hallazgos se enfocan a la prevalencia, mortalidad, tasa de hospitalización, discapacidad, deterioro cognitivo, síntomas depresivos, obesidad, comorbilidades, caídas o fracturas y actividad y rendimiento físico. Conclusiones: Se ha encontrado una elevada prevalencia de fragilidad en el enfermo renal crónico en tratamiento renal sustitutivo con diálisis, sin diferencias entre diálisis peritoneal y hemodiálisis. La fragilidad en estos pacientes está asociada a mayor mortalidad, tasa de hospitalización, discapacidad, deterioro cognitivo, síntomas depresivos y comorbilidades. La actividad y rendimiento físico, parecen ser factores que disminuyen la fragilidad.

Introducción: Ser personal sanitario en activo supone un factor de riesgo elevado para contraer la infección por SAR-CoV-2. La realización de programas de vacunación es la mejor herramienta disponible para enfrentar este problema. En España, los profesionales sanitarios han sido vacunados de manera prioritaria. Objetivos: Evaluar, a través del recuento de anticuerpos en sangre, la inmunogenicidad de las vacunas frente a SARS-CoV-2 en personal de diálisis y los factores relacionados con ella. Material y Método: Estudio observacional descriptivo de corte trasversal, multicéntrico. Se realizó una determinación serológica del recuento de anticuerpos totales anti-proteína “S” en las 12 semanas posteriores a la vacunación. La recogida de datos se realizó a través de un cuestionario ad-hoc, online, anónimo y voluntario. Resultados: 167 participantes, todos vacunados con vacunas ARN. EL 15% había pasado previamente la infección. El 96,4% han desarrollado anticuerpos (media de 15.776±13.640 AU/ml); aquellos profesionales que han pasado previamente la infección tienen un número promedio de anticuerpos significativamente mayor que los que no (23.532 vs 14.381 AU/ml) (p=0,05). La presencia de síntomas como cansancio, cefalea, fiebre y mialgias se asocia, también, a una reactividad significativamente mayor (p=0,004). No existe relación significativa entre la reactividad y sexo, edad, índice de masa corporal (IMC) o lugar de trabajo. Conclusiones: La inmunogenicidad provocada por las vacunas ARN administradas a personal de diálisis ha sido casi total. Padecer efectos adversos post vacunación, como cansancio, cefaleas, fiebre, náuseas y dolores, y haber pasado previamente la infección se asocia con mayor reactividad

Published: September 2021

Introducción: El control del fósforo en pacientes en hemodiálisis es muy importante para la prevención de complicaciones. Objetivo principal: Evaluar los niveles de fósforo en sangre antes, durante y después de las intervenciones médica y enfermera-médica. Material y Método: Estudio cuantitativo, analítico, cuasi experimental, longitudinal y prospectivo en una población de pacientes en hemodiálisis hospitalaria. El estudio tuvo una duración de 18 meses donde enfermeras y médicos en diferentes meses controlaron la prescripción de los quelantes del fósforo. Se recogieron datos de los resultados analíticos y se reforzó la pauta dietética por parte de las enfermeras. Se administró el test de Morisky Green para valorar la adherencia al tratamiento, así como un “check list” para valorar los efectos secundarios de los quelantes. Resultados: Se estudiaron 19 pacientes. Los niveles de fósforo (mediana; rango intercuartílico) en los distintos periodos fueron de: (4,8; 1,3) mg/dl en el periodo previo, (4,5; 1,9) mg/dl en el periodo médico y (4,5; 0,9 mg/dl) en el periodo enfermera-médico. Se compararon los resultados entre los diferentes periodos y no se observaron diferencias estadísticamente significativas entre los niveles de fósforo. Tampoco se observaron diferencias en dichos niveles al separar los pacientes cumplidores de los no cumplidores. Conclusiones: Aunque los resultados no fueron estadísticamente diferentes, se observó una disminución del fósforo con el refuerzo de dieta continuo por parte de las enfermeras. Por lo que se concluye que las enfermeras, junto con el apoyo médico, podrían implicarse en la prescripción y el control de fósforo mensual de los pacientes.

Bir ülkenin ana kaynağı olan tarım, ekonomik kalkınmanın da en önemli temel taşlarından biridir. Her toplum için hayati öneme sahip olan tarım sektörü, ekonomik gelişmişliğin de önemli bir unsurudur. Türk Dil Kurumu’nun yayınladığı Türkçe Sözlük’te “bitkisel ve hayvansal ürünlerin üretilmesi, kalite ve verimlerinin yükseltilmesi, uygun koşullarda korunması, işlenip değerlendirilmesi ve pazarlanması, ziraat ve kültür” olarak ifade edilmekte olan tarım, ülke ve toplumun kalkınmasında önemli rol oynamakta olup, ekonomik sistemin küreselleşmesi, rekabet ortamının yoğunlaşması ve piyasa koşullarının hızlı değişmesi ile giderek daha fazla önem kazanmış ve toplumun sağlığı ve gelişimi üzerinde önemli etkilere sahip olmuştur.

Bu bağlamda Türkistan’ın en geniş topraklarına sahip, gelişmekte olan Orta Asya Türk Cumhuriyetleri’nden biri ve yüzölçümü bakımından dünyanın dokuzuncu ülkesi olan Kazakistan yüksek tarım potansiyeline sahiptir.

Bu çalışmada Sovyet Sosyalist Cumhuriyetleri Birliğinin dağılmasından sonra bölgede kurulan milli devletler içerisinde tarım potansiyeli yüksek işlenebilir toprakların beşte birine sahip, günümüzde zirai mahsul üreticisi ve ihracatçısı olan Kazakistan’da tarımın XIX. Yüzyılda Kazak toplumunda sosyo –ekonomik açıdan önemi üzerinde durulacaktır. Çalışmanın temelini Kazak bilim adamı Çokan Çingisoviç Valihanov’un birincil kaynak olan Sobraniye Soçineniy V Piyatı Tomah adlı ansiklopedik derlemenin birinci cildinde yer alan “O Hlebopaşestve-Tarım Hakkında” adlı eseri oluşturmaktadır.

In this study, it was aimed to determine the current status and problems in terms of technical and structural conditions of beef cattle barns structures in Adıyaman city center and its districts, in the T.C. İpekyolu Development Agency (İKA) in TRC1 Region. The construction materials used in beef cattles, the dimensions of the structural elements, the levels of automation and mechanization, the product design and the problems faced by the manufacturers were determined. For this purpose, in line with the data obtained from Adıyaman provincial and district Agricultural Directorates, observations and measurements were made by going to all beef cattle enterprises and surveys were applied to each of the business owners to determine the technical and structural problems of the enterprises. According to the results of the survey, measurement, and observation, it was determined that all of the enterprises belong to the owners of the enterprises and all the shelters were planned as Open Beef Cattle Barns. 22.5% of the barns were built with the own money of the business owners, 5% by using loans, and 72.5% by getting both support and grant aid from the state. It was determined that 7,5% of beef cattle shelters had no roughage storage, 5% had no concentrated feed storage and 70% had no silage feed storage. As a result of the statistical analysis on beef cattle enterprises, a significant relationship was found between the construction years of cattle barns and needs to the renewal of barns or not (p<0.01). In addition between the number of animals in shelters and utilization status from government supporting programs such as credit, support and grants of business owners, and between the number of animals in farms and the presence or not of manure storage in the farms, a significant relationship was determined (p<0.01).

This study was designed prospectively to investigate the demographic data of the patients who had blood and blood products in Dicle University Medical Faculty Research Hospital Emergency Service between 01 November 2014- 01 November 2015, also to investigate the indications for blood products used, the amount and the type of the products used. When we look at the diagnosis of patients who underwent transfusion in the emergency department; It was determined that 26.2% were transfused for malignancy, 32.6% for anemia, 18.3% for trauma, 12.5% for GIS bleeding, and 10.4% for other reasons. The patients who had blood product transfusion were 623; 53.8% were male and 46.2% were female. The mean age of the patients was determined 47.87±23.66. The percentage of transfused blood products were as following: 83.6% erythrocyte suspension (ES), 17.3% fresh frozen plasma (FFP), 17.3 % platelet suspension(PS), 0.6% whole blood(WB), %4.3 other blood components (OBC). As a result, we can say that in our study, a large number of transfusions were performed in the emergency department, a specific protocol was not adhered to in determining the indication, and transfusion was performed in support of patients who were mostly under outpatient follow-up. Emergency transfusion decisions should be performed with true emergency indication, follow-up with clinical response rather than laboratory response, and consciousness about the aim of transfusion.

In this study, extrusion method, which is one of the cold forming methods of elbow pipes, has been investigated. When the literature is examined, the production conditions of steel pipes and the problems that occur in production have been examined by different people and suggestions have been made. In this study, the production process of AISI 316L (EN 1.4404) quality stainless steel elbow pipes has been investigated. The mold design model created with the Solidworks program was transferred to the non-linear finite element analysis software ANSYS program for simulations. The process was modeled and simulated in the transient structural analysis section of the ANSYS program. In the process of transforming the pipe into an elbow product, we have learned about the stress distributions and obtaining the total deformation changes on the elbow. The parameters of the production process have been optimized by comparing the work done in the simulation and experimental data. In this way, cost-effective production is aimed by minimizing production costs. The data was extracted by simulating the production environment and conditions.

Published: September 2021

Due to the sudden outbreak of COVID-19, there has been a rapid transformation of the learning and teaching environment from face-to-face to fully online classes. Students being at home in isolated home environments challenged the language learning process profoundly which forced teachers to update and adjust their instructional strategies and activities by including collaborative learning elements. Implementing novel technologies with OCL approach might act as a considerably efficient factor if learner characteristics and the educational setting are taken into consideration seriously. Therefore, the purpose of the study is to explore an online collaborative writing tool and students’ opinions towards it. The participants of the study consist of 30 students studying at a preparatory school at a state university in Istanbul. To this aim, both quantitative and qualitative methods have been benefited. According to the quantitative data, the calculated mean scores of the items revealed that the majority of students found the experience of OCW positive. As for the qualitative data, the content analysis showed that the majority of the students reported the benefits of interaction and social learning taking place in collaborative learning, and there were also some disadvantages mentioned by the participants such as disagreements, social loafing, and personality-related problems.

Authors: Catoire Pascale , Schneewele Manuel , Tesson Sonia , Tricard Elodie
Published: September 2021

The lockdown, announced on March 16, 2020, led to a massive use of digital tools to offer pedagogical continuity. The objective of this exploratory research is to highlight the digital practices of 1, 994 teachers took part in this research from May to July 2020. A questionnaire measuring their digital practices during the lockdown, as well as the factors of change, was sent to them by email. Although the use of digital tools increased during the lockdown, the underlying pedagogical practices have not changed much. Teachers report that they mainly used digital tools to maintain communication as well as for the deposit, storage and sharing of content, thereby reproducing what is done in class. The results of this study targeting teachers’ practices support the idea that the appropriation of digital tools should be considered over a long period of time and through a change in teaching practices.

The closing of schools at the beginning of spring 2020, because of the Corona Virus pandemic, featured the need for School Distance Education (SDE). Nevertheless, teachers did not have previous experience in SDE and as a result, they were in need of support in this urgent situation. The Laboratory for Advanced Teaching Technologies for Lifelong Learning and Distance Education (e-Learning Lab) of the University of Crete, attempted to contribute with its own means to the support of teachers who struggled to respond to the challenges of distance teaching resulting from the suspension of schools. Within the above framework, fast track distance seminars were designed and implemented, aiming at the support of teachers on pedagogical issues of Distance Education. During the period from 19 March to 29 April 2020, 20 distance training seminars were conducted, in which more than 40,000 teachers of primary and secondary education from around Greece participated. The overall presentation and assessment of the training actions showed not only the enormous interest of the teaching community but also the need for such training actions with particular emphasis on the principles and the methodology of SDE, on synchronous and asynchronous learning environment as well as the designing or planning of teaching scenarios based on the pedagogical approaches compatible with Distance Learning.
ArguMente: An Online Argumentation System for Formal and Non-Formal Education
Authors: Enríquez Larisa , Hernández Myrna
Published: September 2021

ArguMente is an online system that offers two types of learning spaces. On the one hand, a close group space that implements a student-centred teaching strategy, the purpose of which is to automate the Dialogue Design System model for written argumentation (DDS). On the other hand, it offers a space for the exercise of an argued debate under a non-formal environment of education that calls for the creation of learning communities. Experiences for teaching argumentative skills and for teaching teachers have taken place through the first space, the closed classroom, while the second space, the open classroom, is being used to promote the autonomous argumentative dialogue.

Published: September 2021

The global pandemic caused by the Covid-19 outbreak and the subsequent mandatory lockdown made university students spend more time at home, changing their daily habits including studying, as a consequence of the forced self-confinement. In this article we describe the changes observed in the connection patterns to the institutional learning management system of the students enrolled in a Spanish online university during the lockdown. Our results show that the students were more likely to connect to the virtual campus, they did so more evenly over the days of the week, and more concentrated in a few hours in the central part of the days. Interestingly, the changes in students’ connection patterns were not associated with their socio-demographic characteristics, although they were affected by their academic trajectory and their academic enrolment.

This paper presents a pilot research of approaches taken by European Union (EU) Member States (MSs) in the emergency response to the COVID-19 crisis in pre-tertiary education. It includes a multi-case study of four MSs, examining their education systems’ digital readiness and “fitness for change”, as well as decision-making practices. We use the Cynefin framework of decision contexts to explore different paths in shifting from chaos to complexity. The preliminary findings of this research indicate that a factor positively influencing education systems’ response was not exclusively their digital readiness, but also “fitness” in terms of ongoing reforms and preparedness for change. The findings also suggest that MSs generally continued with their usual decision-making practices, with tendencies towards centralisation of crucial decisions, which is in line with the Cynefin framework, arguing for stronger leadership in chaotic contexts.

Published: September 2021

The article considers the evolution of scientific approaches to the essence of the concept of "logistics activities". In particular, the concepts provided by different scientists from the standpoint of systemic, functional, economic and process approach are systematized. Control objects are defined depending on each approach. The property of logistics activity as interaction with the external environment is emphasized. It is substantiated that the interaction with the external environment occurs through timely and reliable exchange of information. The main prerequisites for the implementation of logistics activities, such as: globalization, technological progress, knowledge economy. The nature and features of each of the prerequisites for the implementation of logistics activities are revealed. The importance of the concept of prevention of negative impact on the environment is emphasized. Within this concept, "green logistics activities" are gaining popularity, which are aimed at saving energy, materials, efficient land use, reducing air pollution, by reducing the number of lands, air, water transport, noise and hazardous waste regulation. A manifestation of the environmental approach in logistics is reversible logistics, i.e. logistics that involves the return of goods and waste. Taking into account the considered approaches, the definition of logistics activity is given.

The article is designed and formulated to define and ensure sustainable development of urban passenger transport, which is an essential component of the business strategies of enterprises automobile and highway transportation and promoting of the development of transport traffic. The article describes and investigates the current state of infrastructure and activities of urban passenger transport enterprises, namely the quality of services, existing conditions, internal and external factors of development of urban passenger transport enterprises. Covers the main problems of activity in the field of urban passenger transport, offers a methodology for developing measures to ensure sustainable development of urban passenger transport enterprises to maintain the quality and economic efficiency of such enterprises. Thereby providing existing social needs and defines a ways to meet them. The study based the mechanism on the renewal of rolling stock in accordance with the Euro-5 standard (in accordance with the procedure for conducting a tender for passenger transportation and the procedure for state technical inspection) to ensure the environmental component and improve the quality of transport services. The development of the mechanism for ensuring the sustainable development of enterprises is the initial event in the process of ensuring and calculating the effect of the organizational and economic mechanism for ensuring the sustainable development of urban passenger transport enterprises. This mechanism will provide a solid foundation for sustainable development of the transport industry and the creation of a free and competitive market for transport services. It is also necessary to understand the strong factor impact on an extensive system of this scale, so the implementation of this mechanism should prepare not only the calculation of resources for direct support of the process, but also the staff who will coordinate the implementation of the mechanism. The use of such a mechanism encompasses and encourages all participants in the interaction to make certain efforts with motivation for the joint positive effect of its implementation.
Asymmetric Distribution of the Solar Photospheric Magnetic-Field Values

Published: September 2021

Understanding the characteristics of the solar magnetic field is essential for interpreting solar activities and dynamo. In this research, we investigated the asymmetric distribution of the solar photospheric magnetic-field values, using synoptic charts constructed from space-borne high-resolution magnetograms. It is demonstrated that the Lorentzian function describes the distribution of magnetic-field values in the synoptic charts much better than the Gaussian function and this should reflect the gradual decay process from strong to weak magnetic fields. The asymmetry values are calculated under several circumstances, and the results generally show two periodicities related to the variation of the solar B
0 angle and the solar cycle, respectively. We argue that it is the small-scale magnetic fields, the inclination of the solar axis, the emergence and evolution of magnetic flux, and the polar fields that are responsible for the features of asymmetry values. We further determined the polar-field reversal time of solar cycles 23 and 24 with the flip of asymmetry values. Specifically, for cycle 24, we assert that the polar polarities of both hemispheres reversed at the same time—in 2014 March; as to cycle 23, the reversal time of the S-hemisphere is 2001 March, while the determination of the N-hemisphere is hampered by missing data.

The first binary neutron star merger has already been detected in gravitational waves. The signal was accompanied by an electromagnetic counterpart including a kilonova component powered by the decay of radioactive nuclei, as well as a short γ-ray burst. In order to understand the radioactively powered signal, it is necessary to simulate the outflows and their nucleosynthesis from the post-merger disk. Simulating the disk and predicting the composition of the outflows requires general relativistic magnetohydrodynamical (GRMHD) simulations that include a realistic, finite-temperature equation of state (EOS) and self-consistently calculating the impact of neutrinos. In this work, we detail the implementation of a finite-temperature EOS and the treatment of neutrinos in the GRMHD code HARM3D+NUC, based on HARM3D. We include formal tests of both the finite-temperature EOS and the neutrino-leakage scheme. We further test the code by showing that, given conditions similar to those of published remnant disks following neutron star mergers, it reproduces both recombination of free nucleons to a neutron-rich composition and excitation of a thermal wind.

We present a new transit of TRAPPIST-1 d from 2021 August 25. The measured mid-point of this transit agrees with the prediction from a recently published dynamical model for the TRAPPIST-1 system and differs significantly from a naive prediction from a simple linear ephemeris. This difference underlines the importance for using dynamical models to predict future transit times in the TRAPPIST-1 system.

Cette recherche a pour objectif d’examiner les traits de l’intelligence émotionnelle (TEI) en tant que prédicteur de l’adaptabilité de carrière en évaluant les rôles modérateurs de la culture (pays d’origine) et du sexe. Ce travail se fonde sur la théorie de la construction de carrière (Savickas, 2005, 2013), la théorie de l’action du développement de carrière (Young et al ., 1996) et sur les recherches d’Hofstede (1980, 2001). A partir d’un échantillon composé de 349 étudiants originaires deux universités (l’une française et l’autre argentine), les résultats ont révélé que les 4 facteurs de l’intelligence émotionnelle étaient positivement liés à l’adaptabilité de carrière. Ces résultats contribuent à la littérature sur la théorie des carrières en améliorant la compréhension des prédicteurs de l’adaptabilité professionnelle des jeunes dans deux contextes culturels différents.
Quand la gendarmerie devient participative : l’engagement des voisin·es dans les réseaux officiels de vigilance en France
Authors: Elguezabal Eleonora
Published: September 2021

Les dispositifs participatifs de vigilance se développent en France depuis plus d’une décennie par des partenariats entre les mairies et les forces publiques de police, notamment dans les zones sous compétence de la gendarmerie. Faut-il y voir un rapprochement des forces de l’ordre avec la population, une ouverture des polices d’État aux citoyen·nes ? Ou une forme de vigilantisme ? En matière de sécurité, la participation serait-elle du côté des mobilisations conservatrices plutôt que réformatrices ? Grâce à une enquête de terrain, nous nous plaçons du côté des personnes qui se portent volontaires pour comprendre leurs engagements.
Les fonds océaniques, un espace stratégique pour les armées françaises
Authors: Soubrier Jean-Baptiste
Published: September 2021

Alors que la première puissance navale mondiale consacre déjà un domaine de lutte spécifique au «  seabed warfare  », la France, qui a fait partie des pionniers dans la conquête des abysses, réfléchit à se doter d’une stratégie militaire de maîtrise des fonds marins. Le double enjeu pour les forces armées est de garantir la liberté d’action de nos forces et d’être en mesure de protéger les intérêts nationaux qui y reposent. Cette stratégie de puissance ne pourra se faire sans une dynamique d’accompagnement interministériel. Elle permettra de relever, avec nos partenaires, le défi de l’utilisation libre, pacifique et raisonnée des fonds marins internationaux. Notre domaine sous-maritime le plus vaste au monde nous y oblige.
