On note de nos jours une intensification, aux États-Unis, de l’usage de la race en santé publique, une idée qui est parfois rejetée dans la mesure où elle est associée à des pratiques controversées. Les races sont vues, dans ce contexte, comme le produit du racisme, une technologie du pouvoir de l’État moderne qui a consisté à fragmenter l’humanité pour permettre les colonisations. C'est ainsi que la race a été prise en charge par le discours pour marquer la différence, discours qui est constitué d'un ensemble hétérogène de dispositifs, des institutions, des énoncés scientifiques, des normes et des règles. Le racisme s’est développé en parallèle avec l'affirmation d'un pouvoir sur la vie visant à assurer la gestion des corps et des populations, notamment par le biais des pratiques de santé publique. Cette thèse s'appuie sur une étude ethnographique réalisée sur un corpus de documents de la santé publique parus aux États-Unis et issus de bureaux fédéraux et d’une importante revue spécialisée dans le domaine sanitaire, et qui ont été publiés entre 2001 et 2009. Cette étude a analysé la manière dont la race est représentée, produite comme objet de connaissance, et régulée par les pratiques discursives dans ces documents. Les résultats confirment que le discours sur la race varie au cours du temps. Toutefois, les résultats indiquent la relative permanence en santé publique d'un régime racialisé de représentation qui consiste à identifier, à situer et à opposer les sujets et les groupes à partir de labels standardisés. Ce régime est composé d'un ensemble de pratiques représentationnelles qui, couplées aux techniques disciplinaires et à l’idée de culture, aboutissent à la caractérisation et à la formation d’objets racialisés et à des stéréotypes. De plus, cet ensemble d’opérations qui fabrique la racialisation, a tendance, avec la sanitarisation et la culturalisation, à naturaliser la différence, à reproduire l’ordre symbolique et à constituer les identités raciales. Par ailleurs, la racialisation apparaît tiraillée entre un pouvoir sur la vie et un pouvoir sur la mort. Enfin, cette étude propose une alternative postraciale qui envisage la constitution des groupes humains de manière fluide et déterritorialisée.

The pedagogic device is constituted as a network of relationships that can be established between heterogeneous elements such as discourses, institutions, laws, administrative measures, scientific statements, philosophical propositions, ie, the said and unsaid. This paper aims to present an analysis on the theme "teacher training" from the perspective of the French philosopher Michel Foucault and his concept of the device. We performed the analysis of texts of the Patio magazine specializing in education.

This article aims to question the knowledge created with psychology, taking a quick passage through the discourses of this science since its birth and questioning what is the implication of this knowledge to the children constituition. Then, we will reassemble the context in which it was forged and what revolutions in the ways of conceiving life became possible after the psychology advent being estabilished as a field of autonomous knowledge. Furthermore, as a way to illustrate what we understand about the psychology constituition of childhood we will discuss some aspects of Jean Piaget's theory in an attempt to elucidate how this speach was (and is) widely applied and "naturalized" in such way, that nowadays it is common to speak of "stages of development" when referring to children. To realize that problem, we will support the studies of Michel Foucault about the production of knoledge and especially of knowledge “psy” and what is its importance for the children.

The aims of this study were to investigate the beliefs concerning the philosophy of science held by practising science teachers and to relate those beliefs to their pupils' understanding of the philosophy of science. Three philosophies of science, differing in the way they relate experimental work to other parts of the scientific enterprise, are described. By the use of questionnaire techniques, teachers of four extreme types were identified. These are: the H type or hypothetico-deductivist teacher, who sees experiments as potential falsifiers of hypotheses or of logical deductions from them; the I type or inductivist teacher, who regards experiments mainly as a way of increasing the range of observations available for recording before patterns are noted and inductive generalisation is carried out; the V type or verificationist teacher, who expects experiments to provide proof and to demonstrate the truth or accuracy of scientific statements; and the 0 type, who has no discernible philosophical beliefs about the nature of science or its methodology. Following interviews of selected teachers to check their responses to the questionnaire and to determine their normal teaching methods, an experiment was organised in which parallel groups were given H, I and V type teaching in the normal school situation during most of one academic year. Using pre-test and post-test scores on a specially developed test of pupil understanding of the philosophy of science, it was shown that pupils were positively affected by their teacher's implied philosophy of science. There was also some indication that V type teaching improved marks obtained in school science examinations, but appeared to discourage the more able from continuing the study of science. Effects were also noted on vocabulary used by pupils to describe scientists and their activities.

The automatic transformation of sequential programs for efficient execution on parallel computers involves a number of analyses and restructurings of the input. Some of these analyses are based on computing array sections, a compact description of a range of array elements. Array sections describe the set of array elements that are either read or written by program statements. These sections can be compactly represented using shape descriptors such as regular sections, simple sections, or generalized convex regions. However, binary operations such as Union performed on these representations do not satisfy a straightforward closure property, e.g., if the operands to Union are convex, the result may be nonconvex. Approximations are resorted to in order to satisfy this closure property. These approximations introduce imprecision in the analyses and, furthermore, the imprecisions resulting from successive operations have a cumulative effect. Delayed merging is a technique suggested and used in some of the existing analyses to minimize the effects of approximation. However, this technique does not guarantee an exact solution in a general setting. This article presents a generalized technique to precisely compute Union which can overcome these imprecisions.

In August 23-25, 2007, the Scandinavian Society for Prosthetic Dentistry in collaboration with the Danish Society of Oral Implantology arranged a consensus conference on the topic 'Implants and/or teeth'. It was preceded by a workshop in which eight focused questions were raised and answered in eight review articles using a systematic approach. Twenty-eight academicians and clinicians discussed the eight review papers with the purpose to reach consensus on questions relevant for the topic. At the conference the consensus statements were presented as well as lectures based on the review articles. In this article the methods used at the consensus workshop are briefly described followed by the statements with comments.
