El presente artículo desea reflexionar, por un lado, sobre la necesidad de una formación integral de los agentes sanitarios, que contemple la dimensión espiritual; y, por otro lado, sobre la necesidad de una mejor preparación de los agentes religiosos que trabajan en hospitales y centros de salud, para que en sus intereses y preocupaciones por los enfermos, se eviten las dicotomías en nombre de la fe o en nombre de la razón. La promoción del diálogo entre razón y fe reduce (...) la distancia entre las ciencias y evita el divorcio entre la praxis de la fe y la praxis de la ciencia, revelando que, a pesar de ser distintas por sus grados de certeza, pueden estar próximas por el objeto: la búsqueda de la verdad que libera al ser humano de todas las formas de injusticia y opresión, generadoras de malestar y enfermedades sicosomáticas. This paper intends to reflect, on one hand, the need for an integral education of healthcare agents, that addresses the spiritual dimension; and, on the other hand, the need for a better preparation of religious agents that work in hopitals and health centers, so that, in the interest and concern for sick people, dichotomies in the name of faith or in the name of reason are prevented. The promotion of dialogue between reason and faith shortens the distance between sciences and avoids a divorce between praxis of faith and praxis of science, showing that, despite the different degrees of certainty, may be close by the object: the search for the truth that liberates human beings of all forms of injustice and oppression, disease generators and psychosomatic illnesses.

For many years, the game of chess has provided an invaluable task environment for research on cognition, in particular on the differences between novices and experts and the learning that removes these differences, and upon the structure of human memory and its paramaters. The template theory presented by Gobet and Simon based on the EPAM theory offers precise predictions on cognitive processes during the presentation and recall of chess positions. This article describes the behavior of CHREST, a computer implementation of (...) the template theory, in a memory task when the presentation time is varied from one second to sixty, on the recall of game and random positions, and compares the model to human data. Strong players are better than weak players in both types of positions, especially with long presentation times, but even after brief presentations. CHREST predicts the data, both qualitatively and quantitatively. Strong players' superiority with random positions is explained by the large number of chunks they hold in LTM. Their excellent recall with short presentation times is explained by templates, a special class of chunks. CHREST is compared to other theories of chess skill, which either cannot account for the superiority of Masters in random positions or predict too strong a performance of Masters in such positions.

Electron microscopic examination of the non‐granulated cells of the adenohypophysis of several species has evidenced a unity of structure amongst vertebrates. Efforts to correlate structure and function have been made, but they have often been hampered by the scarcity or absence of direct experimental methods for the investigation of their function. Yet often the evidence in favor of a given role has been circumstantial, relying on coincidences between changes in the secretory activity of the gland and changes in the ultrastructure (...) of the non‐granulated cells or in colloid production. At the present time, the prevailing hypothesis is that, in addition to a possible role in mechanical support within the gland, the non‐granulated cells seem to be important with respect to the secretory process of the endocrine cells and/or to the metabolism of the adenohypophysis.

Understanding how look-ahead search and pattern recognition interact is one of the important research questions in the study of expert problem solving. This paper examines the implications of the template theory Gobet & Simon, 1996a , a recent theory of expert memory, on the theory of problem solving in chess. Templates are chunks Chase & Simon, 1973 that have evolved into more complex data structures and that possess slots allowing values to be encoded rapidly. Templates may facilitate search in three (...) ways: a by allowing information to be stored into LTM rapidly; b by allowing a search in the template space in addition to a search in the move space; and c by compensating loss in the minds eye due to interference and decay. A computer model implementing the main ideas of the theory is presented, and simulations of its search behaviour are discussed. The template theory accounts for the slight skill difference in average depth of search found in chess players, as well as for other empirical data. (shrink)

In a famous study of expert problem solving, de Groot (1946/1978) examined how chess players found the best move. He reported that there was little difference in the way that the best players (Grand Masters) and very good players (Candidate Masters) searched the board. Although this result has been regularly cited in studies of expertise, it is frequently misquoted. It is often claimed that de Groot found no difference in the way that experts and novices investigate a problem. Comparison of (...) expert and novice chess players on de Groot's problem shows that there are clear differences in their search patterns. We discuss the troublesome theoretical and practical consequences of incorrectly reporting de Groot's findings. (shrink)

The Poetic Structure of the World is a major reconsideration of a crucial turningpoint in Western thought and culture: the heliocentric revolution of Copernicus and Kepler. FernandHallyn treats the work of these two figures not simply in terms of the history of science orastronomy, but as events embedded in a wider field of images, symbols, texts, and practices. Thesenew representations of the universe, he insists, cannot be explained by recourse to explanations of"genius" or "intuition."Instead, Hallyn investigates the problem of how (...) new scientific hypothesesare actually formed and the complex way in which certain facts and not others are selected tosupport a particular theory. He contends that the scientific imagination is not fundamentallydifferent from a mythic or poetic imagination and that the work of Copernicus and Kepler must beexamined on the level of rhetorical structure. Hallyn shows the sun-centered universe to beinseparable from the aesthetic, epistemological, theological, and social imperatives of bothneoplatonism and mannerism in the sixteenth centuryFernand Hallyn is a Professor in the Departmentof French Literature at the University of Ghent.

The aim of this text is to present the evolution of the relation between the concept of number and magnitude in ancient Greek mathematics. We will briefly revise the Pythagorean program and its crisis with the discovery of incommensurable magnitudes. Next, we move to the work of Eudoxus and present its advances. He improved the Pythagorean theory of proportions, so that it could also treat incommensurable magnitudes. We will see that, as the time passed by, the existence of incommensurable magnitudes (...) was no longer something strange. Already in the period of Plato and Aristotle, their existence was common place: up to the point of being considered absurd that all magnitudes were commensurable. Aristotle criticized the Pythagorean program and defended that, though belonging to the same category, number and magnitude are of distinct species: number is discrete and magnitude is continuous. We finish by presenting briefly how the concept of number was amplified throughout the centuries until it came also to include the notion of continuity. (shrink)

La vie et les oeuvres de J. H. Newman ont suscité de nombreux et importants travaux. L'étude de l'homme lui-même a servi de thème à plusieurs ouvrages ; on a cherché à discerner dans son tempérament la raison de l'originalité de son œuvre ou de l'étendue de son influence ; ailleurs on nous a fait connaitre l'historien, le philosophe, le théologien, mais de tous ces Newman divers, l'éducateur est resté le plus ignoré. Cette constatation fut le point de départ de (...) la présente étude. Or l'éducation, cette activité privilégiée, a si bien été le centre même de la vie de Newman, qu'à elle nous devons non seulement un de ses chefs-d'œuvre les plus achevés, (malheureusement trop peu connu de ceux qui se réclament du Newman du Développement ou de l'Assentiment, voire de celui de l'Apologia), mais presque toutes ses œuvres. Il n'a que bien rarement, peut-être jamais, écrit pour écrire ; il a écrit pour enseigner, et à son âme d'éducateur est dû le caractère particulier de son oeuvre. (shrink)
