Fractalité et histoire migratoire d’Homo sapiens

2012

Resume L’homme moderne (Homo sapiens), originaire d’Afrique il y a moins de 150 000 ans environ, a effectue plusieurs migrations a l’interieur de ce continent et en dehors, ce qui lui a permis de coloniser la planete tout en se diversifiant genetiquement. Cette colonisation a ete etudiee par plusieurs specialistes et, en particulier, par L. Cavalli-Sforza qui l’a decrite par un arbre dendritique cladistique proche du diagramme de Feigenbaum, caracteristique des phenomenes de chaos deterministe. Cette similitude permet l’analyse de ce diagramme au moyen de lois fractales des systemes non lineaires qui demontrent une fois de plus l’importance des lois non lineaires dans l’evolution du vivant,…

Are Pseudosciences Like Seagulls? A Discriminant Metacriterion Facilitates the Solution of the Demarcation Problem

In this article, I develop a philosophical framework, or ‘metacriterion’, for the demarcation of pseudoscience. Firstly, ‘gradualist demarcation’ is discussed in depth, considering an approach to t...

An Institutionalist's Journey into the Years of High Theory: John Maurice Clark on the Accelerator-Multiplier Interaction

2007

A few years ago, an article by Arnold Heertje and Peter Heemeijer (2002) triggered an articulate and stimulating debate among scholars on the intellectual origins of Paul Samuelson's multiplier-accelerator model (1939a, 1939b). The discussion, which involved the participation of Samuelson himself, centered on whether, and to what extent, Samuelson's 1939 seminal contributions were inspired by Roy Harrod'sThe Trade Cycle(1936). Heertje and Heemeijer argue that “there is little factual support for Samuelson's suggestion ascribing the model mainly to Alvin Hansen, his mentor in the days of the creation of the model” (Heertje and Heemeijer 2002, p. 207). Instead, they provide convincing evidenc…

Enlightened Female Networks: Gendered Ways of Producing Knowledge (1720-1830)

2022

This special issue investigates women's scientific networks in Europe roughly between 1720 and 1830, an interesting period from a gender point of view. The articles analyse the role that networks played in enabling, shaping and circumscribing women in their intellectual pursuits, social aspirations and ideals. They also focus on the nature of the members' relationships, how women negotiated their scientific identities and how often women could use their femininity to create new social spaces for themselves and their families. We traced different types of networks such as ‘paper’, ‘technical’, ‘distant’ (in its special and temporal sense), ‘moral’ and ‘mixed’, as well as how many of these ne…

Education and the Concept of Time

2013

Abstract As we speak about time in the context of everyday life, we have no problem with what we mean by time. We take time as given. Different kinds of theories of development rely on the ordinary concept of time. Time is a sequence of instants, and we are moving along from the past to the future, from birth to death. Moving in time also means development. It does not take into account how a human being is in the time. It flattens our view of human life and cannot describe our manifold being. According to theories of development, if a child does not behave in a certain instant as the theories expect, there must be a problem with that child or she has not developed as well as others.
