Apprentissage et développement dans l’analyse du travail enseignant

Abstract: Parmi l’heritage que nous a legue l’œuvre de Vygotski apparait de premier plan les questions d’apprentissage et de developpement. Nous tenterons dans cette contribution de revisiter ces questions du point de vue de leur rapport. Pour ce faire, il nous repartir de la ou emerge le probleme, autrement dit des textes de Vygotski eux-memes. La these se distingue de trois autres positions que Vygotski recense (Vygotski, 1933/1985; Vygotski 1934/1997; Riviere, 1990).

Refractometer for Tracking Changes in the Refractive Index of Air Near 780 nm

Abstract: A new system, consisting of a double channel Fabry Perot etalon and laser diodes emitting around 780 nm is described and proposed to be used for air refractive index measurements. The principle of this refractometer is based on frequency measurements between optical laser sources. It permits quasi-instantaneous measurement with a resolution better than and uncertainty in the range. Some preliminary results on the stability of this system and the measurements of the refractive index of air with this apparatus are presented. The first measurements of the index of air at 780 nm are, within an experimental uncertainty of the order of, in agreement with the predicted values by the so-called revised Edl\'en equations. This result is to the best of our knowledge the first to extend to the near infra-red the validity of the revised Edl\'en equation derived for the wavelength range 350- 650 nm.

Sustainable development: a vague and ambiguous “theory”

Abstract: Purpose – The notion of “sustainable development” has had a short and tumultuous history, including a departure from economic reductionism by focusing on a multidimensional aspect and addressing the issues of its scope across many disciplines. It has become a project enabling a rethinking of capitalism based on the concept of a reformed type of capitalism. The purpose of this paper is to study this issue.Design/methodology/approach – The paper is based on the following arguments: the presentation of sustainable development as a “vague” theory, an empirical proof of this vagueness with regard to corporate actions whose justification is based around the notion of sustainable development, and finally the ambiguities of the notion.Findings – The notion of sustainable development raises the question of an apparent consensus on its correlates: solidarity, responsibility, equity, etc. It tends to establish a protean sense of the firms' responsibility, particularly the larger ones. The largely political dimension...
