Territoires et insécurité en Île-de-France
Authors: Jardin Antoine , Préteceille Edmond , Robert Philippe , Zauberman Renée 
Published: June 2021

Comment la surexposition de la région parisienne à la victimation et à l’insécurité se décline-t-elle dans la diversité de ses territoires ? Dans le but de répondre à cette question, notre étude consiste à subdiviser la région parisienne en unités territoriales caractérisées par leurs victimations, leur insécurité, leur composition socioprofessionnelle et migratoire et leurs comportements électoraux. Le croisement de ces données produit une typologie qui confronte les différentes combinaisons de la victimation et de l’insécurité à la diversité de la composition sociale et politique des territoires en Île-de-France.
Un précurseur de Paul Chevalier ? La vie mouvementée de Claude Bresoul, Franciscain de Tournai, « prebtre religieux apostat et hereticque » (1518-1560)
Authors: Meiss Marjorie 
Published: June 2021

Le 22 avril 1560, Claude Bresoul est arrêté à Cysoing, près de Lille. Identifié comme un Franciscain ayant abandonné son habit religieux et soupçonné d’adhérer aux idées calvinistes, il est confié à l’inquisiteur de Flandre Pierre Titelmans au mois de juillet. Entre temps, il a été interrogé à six reprises par le prévôt et les échevins de Cysoing. Le contenu de ses interrogatoires offre une occasion exceptionnelle de saisir le parcours de l’un de ces nombreux frères mendiants tentés par la Réforme. S’y dessine le portrait d’un homme mal à l’aise dans une vie religieuse choisie trop tôt et réellement séduit par les options théologiques du calvinisme, devenu un membre actif d’un réseau de coreligionnaires déployé de la Flandre wallonne à Anvers. Il n’est pas impossible que son exemple ait inspiré Paul Chevalier : le futur martyr réformé, monté sur le bûcher en 1564, venait en effet d’arriver au couvent des Franciscains de Tournai lorsque le chapitre eut à se prononcer sur le cas de Claude Bresoul.
L’épithalame de Nicolas Bourbon pour Jeanne de Navarre : du mariage réel au mariage idéal
Authors: Laigneau-Fontaine Sylvie 
Published: June 2021

Protégé de Marguerite de Navarre, précepteur de Jeanne d’Albret, le poète Nicolas Bourbon publie en 1549, au moment du mariage de son élève avec Antoine de Bourbon, un long épithalame destiné à célébrer cette union. Or, ce mariage avait été imposé à Marguerite par son neveu Henri II et toutes les sources attestent du mécontentement de la mère de la mariée et du peu de lustre de la cérémonie. Dès lors, pourquoi le poète décide-t-il de chanter un mariage qui déplaisait tant à sa protectrice ? Est-ce pure maladresse de sa part ? L’article veut montrer au contraire que Nicolas Bourbon, conscient du pouvoir d’une poésie aere perennius , a voulu faire de ce mariage, pour l’éternité, un mariage idéal, en demandant à la littérature de corriger la réalité.
La Satyre ménippée et son Supplement : la reconstruction érudite d’un genre ou le pamphlet du déguisement
Authors: Chauffour Julien 
Published: June 2021

Pierre Pithou et le groupe d’érudits auteurs de la Satyre ménippée de la vertu du Catholicon d’Espagne tentent de reconstruire un genre savant, la satire ménippéenne, à partir d’un pamphlet royaliste qui circulait déjà sous forme manuscrite. Imprimée à Tours en 1594, la Satyre ménippée , bien qu’elle présente une esthétique ménippéenne et un tour paradoxal, parle d’une seule voix, celle du camp d’Henri IV : il lui manque le vertige interprétatif que provoque la lecture des grands maîtres du genre, comme Rabelais ou Lucien. Dans l’ajout tardif au texte de la Satyre Ménippée qu’est Le Supplement du Catholicon ou les Nouvelles des Regions de la Lune (1595), attribué à Florent Chrestien, il est possible, alors, de trouver la réponse aux problèmes soulevés par le difficile mariage de Pamphlet et Érudition.
The economics of team sport in Europe: production, monetization, deficit and regulation
Authors: Bouvet Patrice 
Published: June 2021

This article deals with the economics of professional sport in Europe. Its objective is twofold: firstly, to propose a "vertical" vision, from production to the necessary regulation, including the study of the conditions for monetising sports shows produced by professional sports clubs in Europe; secondly, to put forward a general explanation for the persistence of deficits (DNCG data and similar organisations) of many of these clubs. This article deliberately places itself, unlike many other contributions, in a global (macroeconomic) perspective. It underlines: the universality and singularity of the production of sports shows, the specific conditions of their monetisation; presents, the origin of the deficits and the means nowadays chosen by professional clubs to try to cope with them and finally leads to an original proposal for regulation.

Losada, Leandro (2019). Maquiavelo en la Argentina. Usos y Lecturas, 1830-1940. Buenos Aires, Argentina: Katz Editores. 193 páginas.
Authors: Moretti Ignacio Luis 
Published: June 2021

El libro Maquiavelo en la Argentina. Usos y Lecturas, 1830-1940 nos convoca a adentrarnos en las recepciones, circulaciones y lecturas en Argentina de uno de los pensadores políticos que, merced a cierto halo de enigma e incomodidad y al carácter abierto de sus textos, ha sido objeto de una profusa ambivalencia y divergencia en sus lecturas y valoraciones: Nicolás Maquiavelo. Esta profundidad e intensidad es directamente proporcional al cimbronazo que su irrupción ha provocado en el pensamiento político occidental y que, sin ningún lugar a dudas, ha dado a luz a la modernidad política.

Published: June 2021

El presente estudio cuantifica el desafío que supone el logro del objetivo 7 del desarrollo sostenible: Acceso a energía asequible y no contaminante (SDG7) en Bolivia. La solución planteada por el proyecto estima el costo total de provisión de energía eléctrica en todas las poblaciones de Bolivia, considerando factores socioeconómicos relevantes al realizar la planificación de la cobertura total para el país. El proyecto tiene dos etapas: la primera consiste en la recolección de datos y análisis de la demanda, así como de la percepción/visión de las poblaciones con relación en el uso de la energía; la segunda se centra en el análisis de la información y en la generación de resultados. La recolección de datos de campo que contemplan la demanda energética y el comportamiento en el uso y consumo de la energía se realizó en las comunidades de Raqaypampa (Cochabamba) y El Sena (Pando). Las mismas complementaron información obtenida con anterioridad de El Espino (Santa Cruz) y Toconao (Altiplano frontera con Chile).
El Instituto de Investigaciones en Ciencias Sociales (INCISO), ENERGÉTICA y el Centro de Investigaciones en Energía (CIE), con la información recabada y los datos de indicadores del SDSN, estructuraron la composición estándar de una comunidad rural en Bolivia. Con esta información, el programa de generación de curvas de demanda RAMP simuló las demandas para poblaciones en las zonas bajas y altas de Bolivia, contrastando luego con diferentes tecnologías de electrificación; así se calculó el costo más eficiente de las soluciones encontradas. Finalmente, el costo para electrificar de manera total la población boliviana fue estimado y, en particular para electrificar al 100% de la población aislada y dispersa que alcanza a 587 millones de dólares, dando cobertura a 273 286 familias rurales.
On design of a robust decentralized controller for an interconnected multi-area power system with FACTS devices
Authors: Haroun Ali Hamid Gomaa 
Published: June 2021

In this article, a robust active disturbance rejection control (ADRC) is proposed for load frequency control (LFC) of an interconnected multi-area power system. Two widely employed test systems, namely, two-areas and four-areas hydro-thermal power utilities are concerned to validate the efficacy of the suggested method. To enhance the performance of the system, series flexible ac transmission system (FACTS) like thyristor controlled series compensator (TCSC) and thyristor controlled phase shifter (TCPS) are considered. The simulation results indicated that the system performance is improved with the inclusion of FACTS devices. The adjustable parameters of the proposed FACTS controllers are optimized using particle swarm optimization (PSO) algorithm employing an Integral of Time multiplied Absolute Error (ITAE) criterion. The investigations showed that the proposed controller provides better dynamic performance than others from the point of view of settling time, peak over/undershoot. Finally, the sensitivity analysis of the system is inspected by varying the system parameters and operating load conditions from their pre-specified values. It is observed that the suggested controller based optimization algorithm is robust and performs satisfactorily with the variations in operating load conditions, system parameters and load patterns.

Published: June 2021

In this paper we make a summary of psychological investigation about statistics association. The results of experimental study about previous conceptions are shown. This study has comprised the students' judgments of association. Using factorial analysis, we have identified five factors, which determine the structure of students' strategies. We also show a qualitative study about students' strategies in 2 x 2 and r x c contingency tables, scatterplots, and comparison of a numerical variable in different samples. Finally we describe four different misconceptions about statistical association and the conclusions of this paper.
Secuencia de enseñanza sobre el electromagnetismo
Authors: Meneses Villagrá Jesús Ángel , Caballero Sahelices M. Concesa 
Published: June 2021

In orden to plan the teaching sequence of any physical topic, weconsider essential to bear in mind three factors, at least: the scientific problems that arise from the subjects to be studied, the conceptions of the students to whom the teaching is addressed, and above all, the strategies and methodological process to be taken. This paper presents the didactic model, based on a constructivist approach, we use, the university students' conceptions about electromagnetism, the conceptual map where we make explicit our points of view of the concepts we work on, and the group activities we have designed in order to promote the conceptual, methodological and attitudinal change.
La integración del momento de la técnica en el proceso de estudio de campos de problemas de matemáticas
Authors: Bosch M. , Gascón Pérez J. 
Published: June 2021

This article provides a model of mathematical activity which describes it in terms of the study of fields of problems. This model helps us to analyze some didactical phenomena which are characteristic of the present systems of mathematics teaching. Special emphasis is devoted to the relation between the absence of so-called technique work, and some paradoxes about «mathematical creativity». A new didactical device is proposed, the workshop of mathematical practice, in order to bring the technique work alive in the classrooms as an integrating force in the study of mathematical problems. Finally, as an example, one of the workshops designed and tested is described.

Authors: Astolfi Jean-Pierre 
Published: June 2021

The great deal of preconceptions that have been collected in the past ye:ars by sience education researchers, usually lacks the epistemological component. To consider this component will lead us to a more accurate analysis of the obstacles that a student has to overcome through her/his instruction. Is this paper, Astolfi shows the differences between obstacle and preconception, the three stages to overcome an obstacle, and how to use the concept of objective-obstacle to improve science teaching.

Its aim is a better understanding of the influence of the variable forces of friction in bidimensional movements. We have verified the effectiveness of this teaching method through the evaluation of the students' progress during the courses in which we have carried out this practice.
Análisis de errores conceptuales en geología a partir de las expresiones gráficas de los estudiantes
Authors: Lillo Beviá José 
Published: June 2021

Detection of misconceptions by pupil's drawings permits us to have evidence of some misconceptions wich would have gone unnoticed interpreting only their vocal or writing expressions. Investigation on fossil and fossilisation, internal structure of the Earth, origin of mountains and others, reinforces the previous affirmation and permits us to recommend the non -utilisation of sequential drawings containing high conceptual charge, in order to simplify complex geological processes, because that simplification generates new misconceptions.
Introducción de demostraciones prácticas para la enseñanza de la física en las aulas universitarias

Published: June 2021

An analysis about utility, characteristics and structure of the so called «practical dernonstrations» is presented in order to introduce a dynamic element in the classroom. Although in apparent contradiction with didactic modern trends that proclaim «what students are able to do by themselves, teachers should not do», practical demonstrations should be placed in an active methodological approach as a complement in the exposition of the contents, getting some importance concerning student passivity, lack of didactic facilities and high number of students per classroom.

La necesidad de un cambio metodológico en la enseñanza del equilibrio químico: limitaciones del principio de Le Chatelier
Authors: Quílez Pardo J. , Solaz Portolés Joan Josep , Castelló Hernández M. , Sanjosé López V. 
Published: June 2021

This paper studies the didactic approach used in teaching Le Chatelier's Principle, showing that its usual formulation is ambiguous, and reports the way Chemistry textbooks use this principle in some specific cases with no mention of its limitations. The second part of this work analyses the strategies carried out by chemistry teachers when dealing with a specific equilibrium problem. It is shown how the usual methodology practised in both cases may lead to very important misconceptions, so a new methodological performance is proposed to achieve a real significative learning.

"El café tiene cafeína y nos despierta, nos da energía": concepciones sobre la energía química, una buena razón para poner de acuerdo a los profesores de Física y Química y ciencias Naturales
Authors: Gallástegui Otero J. R. , Lorenzo Barral F. M. 
Published: June 2021

A research was carried on students* conceptions about chemical energy. The experimental sample were students from primary level to university. Word association tasks and a paper and pencil question were used as instruments for collecting data. The test revealed that some students share certain alternative conceptions about chemical energy, and that most of them use ideas about chemical energy in a similar way to what people without formal instruction in this issue would do. Some implications for science teaching -learning are suggested.
