Quand les enseignants claquent la porte

2021

International audience; Les démissions de professeurs des écoles, bien que statistiquement limitées, sont un révélateur de la dégradation des conditions de travail des enseignants dans un contexte d’austérité budgétaire, sans que cette question se limite au thème de la revalorisation des salaires.

2-Groups with few rational conjugacy classes

2011

Abstract In this paper we prove the following conjecture of G. Navarro: if G is a finite 2-group with exactly 5 rational conjugacy classes, then G is dihedral, semidihedral or generalized quaternion. We also characterize the 2-groups with 4 rational classes.

Some problems about products of conjugacy classes in finite groups

2020

[EN] We summarize several results about non-simplicity, solvability and normal structure of finite groups related to the number of conjugacy classes appearing in the product or the power of conjugacy classes. We also collect some problems that have only been partially solved.

On the Applicability of the Space Syntax Methodology for the Determination of Street Lighting Classes

2020

Street lighting plays a crucial role in a city’s night landscape and in urban traffic management, influencing users’ comfort and safety. To contain costs of public street lighting systems and to avoid energy waste, illuminance levels on road surfaces must be adequate to fit actual traffic volumes, as prescribed by regulations. This is true not only for motorized roads but also for sidewalks, paths, and pedestrian areas. Regulations in force establish a relationship between road traffic volumes and minimum illuminance levels through the lighting classes selection procedure. Lighting classes selection is based on various para meters among which traffic volume is the most difficult to evaluate…

Comunismo platónico: Revisión crítica de un proyecto utópico y político-social en la Atenas del siglo V a. C.

2016

This paper aims to study the platonic «communism» as an utopian project which was never carried out. We survey the misnamed platonic communism and its forced relationship, with modern communism, which we analyze in depth. Besides that, by reviewing modern authors, we attempt to compare platonic communism with Marxism, searching for its beginning and causes, as well as its socio-politic aspects. Besides, we bear in mind the historical context where it appeared: Athens in the 5th century BC. En este trabajo estudiamos el «comunismo» platónico como un proyecto utópico que nunca se llevó a la práctica. Se analiza el mal denominado comunismo platónico y su forzada relación con el comunismo moder…

Qualifying Building Information Models with Multi-Agent System

2011

6 pages; International audience; This paper presents a new approach combining the 3D elements composing the environment of mobile agents with semantic descriptors from building information models. Our proposal is based on the IFC standard which is used in the field of Civil Engineering to build digital models of buildings during the design phase. The semantic of IFC objects composing the 3D environment is used to select and set up 3D objects and elements of simulation scenarios. The result of this process dynamically generates the input files to the JaSIM environment that performs the simulation.

La mauvaise discipline dans les classes françaises et quelques autres résultats de PISA 2015

2017

National audience; Le résultats de PISA 2015, pour la France, ressemblent à ceux de 2012 : la performance moyenne de nos élèves -en sciences, en compréhension de l'écrit, en mathématiques -, est proche de la moyenne des 34 pays de l'OCDE, ce qui s'observe depuis le début des évaluations PISA. Mais ces performances sont distribuées de façon nettement inéquitable. D'abord parce que les inégalités entre élèves forts et faibles sont particulièrement fortes en France, ensuite parce que les inégalités de performance selon le milieu social sont les plus fortes de l'OCDE. Les élèves qui passent les épreuves de PISA répondent aussi à un questionnaire sur leur expérience scolaire. En 2015, les élèves…

Hybrid bases for varieties of semigroups

2003

We consider the lower part of the lattice of varieties of semigroups. We present finite bases of hybrid identities for the varieties of normal bands, commutative bands and abelian groups of finite exponent. The variety A n,0 of abelian groups provides an example of a variety which has no finite base of hyperidentities (cf. [12]) but has a finite base of hybrid identities.
