Darstellungen nos Princípios da Mecânica e no Tractatus : a representação dos objetos e a figuração do mundo em Hertz e em Wittgenstein

The aim of this thesis is based on the defense of the hypothesis that there are remarkable influences of the physicist Heinrich Hertz s thinking, especially his The Principles of Mechanics (1894), on the Wittgenstein s Tractatus Logico-Philosophicus (1922). From a series of occasions in which Wittgenstein quotes Hertz, it was proposed here to ascertain what extent this could be sustained. Thus, we tried to display Hertz s thinking within a context in which he involves with the analysis and discussions of the mechanics that were previous to Hertz, proposing a kind of purification of these mechanics, presenting his own image. His intention was to present a unique image from which what he calls pseudo-concepts could be understood; that is, force and energy. From this image, it is argued here, Wittgenstein makes use of its substantial elements (material particle, material point and system) in order to construct his ontology as well as the Hertzian notion that we form facts to ourselves . Besides, with his notion of metaphorical network, he uses a Hertzian procedure to determine the operation of a mechanical system through coordinates about Wittgenstein, determining singularity and the non-priority of a scientific theory over the other. However, at no time it is said that Wittgenstein provided some kind of improvement regarding the mechanics of Hertz because it would suggest that both were dealing with the same subjects within the same scope which, obviously, did not occur and Wittgenstein was aware of that. What Wittgenstein does is a reapplication of the elements of the mechanics of Hertz, in a diverse scope, in order to provide his philosophy with determination, generality and formal independence. The importance of this thesis lies in demonstrating that the tribute of the first to the second is permissible.
Efeitos do ensino de contagem sobre a aquisição de comportamento conceitual numérico em crianças pré-escolares

Abstract Although the studies regarding the role of counting in the acquisition of the numeric conceptual behavior has grown and developed in the past few decades, results available in the literature still show experimental and theoretical disagreements. This study aimed to evaluate the effect of training on oral counting in the acquisition of numeric conceptual behavior through the comparison to the performance of children who were not exposed to the training on counting. Participants consisted of eight children, between three and four years old, from a private elementary school in Araraquara city, Sao Paulo, Brazil. The battery of numeric tasks used for this purpose consisted of the following stimuli, all them ranging from 1 to 9: arabic digits (A); sets of pictures of objects and animals with a random spatial distribution (B); printed number-words (C), spoken numbers (D) and naming (E). Participants in both groups were submitted to the following initial tests: oral counting, identity matching (AA, BB, CC), symbolic relations (AB, AC, BA, CA, BC, CB), auditive-visual matching (DA, DB, DC) and naming (EA, EB, EC). Equivalence relations between numbers and quantities (AB, AC and DA) were trained on both groups, experimental (EG) and control (CG), and oral counting was taught to the EG only. Training on counting consisted of the following steps: verification, training and production of the numeric verbal sequence repertoire, and establishment of oneto- one correspondence between numbers and names of elements in a set. The emergence of the BA, BC, CA, CB, DB, DC, EA and EB relations was observed with the EG participants. By the other hand, subsequent tests of training on relations (same as the initial tests) showed the emergence of the BA, DB, DC, EA and EB relations with the CG. In general, EG participants presented better overall scores compared to the CG. The results presented herein point to oral counting as a facilitator for the numerical equivalence.
