Title Mathematical modelling and administrative management
Author SAINT-SERNIN Bertrand
Keywords Model, Répartition
Topic None
Abstract This article discusses the relationship between mathematical models and administrative action in the French educational system. It shows how mathematics can clarify questions related to the distribution of resources, the movement of personnel, the organisation of examinations, etc; but also how the excessive use of relevant models can be harmful. Finally, it looks at how the number of hours taught have evolved over several decades, which has significantly changed pupils' lives without there being any assessment of the consequences of the reforms. From these examples can be derived a portrait of the mathematician who tries to gain a better understanding of society, for whom Marc Barbut must be a model.

Title Marc Barbut and Pareto's Law
Author VALADE Bernard
Keywords Average man, Inequality, Probability, Répartition
Topic None
Abstract Formulated in the late 19 th century, Vilfredo Pareto's law of income distribution has led to a number of studies by economists, sociologists - and also mathematician. In several articles collected in «La Mesure des inégalités», Marc Barbut examined the mathematical aspects of the distribution of wealth by emphasising the probabilistic character of the Pareto argument. His most important contributions reside in pointing out the impact of Georges Sorel's objections, in showing how Pareto was wrong about the intrinsic parameter of the distribution, as well as in revealing the reasons why Pareto decided to stop working in the direction he had initially taken.
