A variação comportamental coloca o organismo em contato com diferentes contingências, possibilitando o fortalecimento de comportamentos incialmente pouco prováveis. Entretanto, a literatura experimental sobre a aprendizagem de comportamentos de baixa probabilidade inicial influenciada por reforçamento da variação tem encontrado diferenças marcantes entre desempenhos de humanos e não humanos. Dentre as variáveis sugeridas como responsáveis por essas diferenças está o controle verbal pelas instruções fornecidas aos humanos que pode interagir com as contingências em vigor. Foram realizados dois experimentos visando o teste dessa variável. No Exp.1 foi analisado o efeito de instruções para descobrir o que deveria ser feito (ID), comparado ao de instruções mínimas (IM). A tarefa consistiu em sequências de quatro pressões em duas teclas (Q e P) de um computador, sendo a ordem dessas teclas na sequência o que diferenciou as 16 sequências possíveis. Após uma linha de base em que os participantes produziam reforços independente da configuração das sequências emitidas, todos foram expostos a duas contingências concorrentes: FR1 contingente à sequência menos emitida na fase anterior (sequência alvo - SA) ou reforçamento de sequências que variassem entre si dentre as 15 restantes. Dois grupos de estudantes universitários participaram desse experimento. Os participantes de um dos grupos (n=14) foram submetidos à instrução ID e os participantes do outro grupo (n=14) foram submetidos à instrução IM. Cada grupo foi subdividido em dois em função do padrão de variação apresentado na linha de base (alto ou baixo). Nenhuma diferença significante foi encontrada entre os grupos como função das instruções, mas o nível de variabilidade apresentado pelos participantes em linha de base se mostrou um preditor consistente da emissão de SAs. Hipotetizou-se que os reforços dispensados em FR 1 na linha de base poderiam ter fortalecido padrões que se mantiveram na fase seguinte, interferindo no eventual efeito das instruções. Para avaliar essa hipótese, foi realizado um segundo experimento, similar ao anterior, no qual foi excluída a fase de linha de base. Dezoito novos estudantes serviram como participantes sendo divididos em grupos ID e IM. Os resultados mostraram não haver diferenças significantes entre os grupos. Sugere-se que, nas condições testadas, a apresentação de vii instruções que especificam uma tarefa de descobrir a regra (ID) não constitui variável significativa na determinação do desempenho dos participantes humanos. Portanto, essa interpretação não parece ser adequada para justificar as diferenças entre humanos e não humanos submetidos a procedimentos aparentemente similares. São apresentadas sugestões de experimentos que poderão contribuir para o melhor entendimento do papel das variáveis envolvidas nessa diferença entre espécies / The behavioral variation puts the organism in contact with different contingencies, therefore strengthening unlikely behaviors. The experimental literature about learning of behaviors of low initial probability influenced by reinforcement of variation, however, has found striking differences between performances of humans and nonhumans. One of the variables suggested as responsible for these differences is the control by verbal instructions given to humans that can interact with the contingencies in place. Two experiments were conducted in order to test this variable. The Exp.1 analyzed the effect of instructions to \"find out what should be done\" (ID), compared to minimal instructions (IM). The task consisted of four presses sequences on two keyboard keys (P and Q), the order of these key presses in the sequence is what differentiated the 16 possible sequences. After a baseline in which the participants produced reinforcement regardless of the configuration of the sequences emitted, all of them were exposed to two competing contingencies: FR1 contingent to the least emitted sequence in the previous phase (target sequence - TS) or reinforcement for variation among the 15 remaining sequences. Two groups of students participated in this experiment. Participants in one group (n = 14) received instruction ID and participants in the other group (n=14) received instruction IM. Each group was subdivided into other two groups depending on the variation pattern shown at baseline (high or low). No significant differences were found between the groups as a function of the instructions, but the level of variability presented by participants at baseline proved to be a consistent predictor of emitting TSs. It was hypothesized that the reinforcements dispensed in FR 1 over baseline patterns could have strengthened the patterns which remained in the next phase, possibly interfering on the effect of the instructions. To assess this hypothesis, a second experiment, similar to the previous one, was performed in which the baseline phase was excluded. Eighteen new students served as participants and were divided into groups and IM and ID. The results showed no significant differences between groups. It is suggested that, under the conditions tested, the presentation of instructions that specify a task of \"discovering the rule\" (ID) is not a significant variable in determining the performance of human participants. Therefore, this interpretation does not seem adequate to explain the differences between human and nonhuman exposed to apparently similar procedures. Experiments that could ix contribute to a better understanding of the role of the variables involved in this difference between species were suggested

Para tanto, foi feita a análise de um movimento de grande duração inserido em uma obra extensa, composta pelo austríaco Gustav Mahler (1860-1911): a Sinfonia nº3. Sobre esta obra foram realizadas três análises: formal segundo Schoenberg e Rosen; motívica, segundo Réti; e schenkeriana, segundo Salzer.Os métodos foram comparados entre si, de modo a identificarem-se as convergências e divergências entre eles; com base nas divergências e convergências, foramindicadas possibilidades de leitura da obra. Ao final, estes resultados foram confrontados com gravações realizadas por grandes orquestras, tendo à frente regentes reconhecidos como grandes intérpretes da obra de Mahler, verifinco como foram solucionados os problemas de divergência analítica e observando, ainda, se as convergências podem ser confirmadas em suas interpretações. / The present Master's Degree dissertation seeks to demonstrate that the utilization of different analytical methods to a single opus, and their posterior comparation, in an efficient method for the study of musical language, particularly of an specific opus, and that, through this procedure, information on theoretical and interpretative interest that go beyond the isolated utilization of each method can be reached. Therefore, three analysis of the first movement of Gustav Mahler's 3rd Symphony were made. The three analysis were; formal, according to Schoenberg and Rosen; motivic according to Réti; and schenkerian, according to Salzer. The methods were compared to each other so it would be possible to identify similarities and differences amont them. Then, based on these similarities and differences, possibilities of reading of the work were indicated. In the end, these results were confronted with recording made by great orchestras, conducted by great maestros well-known as great interpreters of Mahler's opus, verifying how the problems of analytical diffrences were resolved and observing as well if the similarities coud be confirmed in their interpretations.

Esta pesquisa tem como objetivo descrever as orientações de letramento de crianças de uma turma de primeiro e terceiro ano do Ensino Fundamental I de uma escola pública estadual, localizada na zona rural do sul do Brasil, bem como investigar a presença e os usos da escrita das crianças e dos seus familiares fora do contexto escolar. A pesquisa foi realizada por meio de trabalho de campo de nove meses, que envolveu a geração de dados etnográficos na escola e na comunidade por meio de observação participante, gravação audiovisual das aulas, entrevistas com os professores e membros da comunidade, registros fotográficos e coleta de documentos. A fundamentação teórica que orientou todo o processo investigativo está baseada nos Novos Estudos sobre Letramentos (HEATH, 1982,1983, 2012; STREET, 1984; BARTON, 2007), os quais entendem letramento como um conjunto de práticas sociais que envolvem a leitura e a escrita e que estão inscritas em um contexto cultural específico. Os principais conceitos que guiam este trabalho são o de letramento (BARTON; HAMILTON, 1998), eventos de letramento (HEATH, 1982) e práticas de letramento (BARTON, 2007). Por meio da análise dos dados, concluímos que há, dentro da escola, orientações de letramento alinhadas à valorização de um conhecimento construído socialmente e que está diretamente conectada à configuração socioeconômica dos grupos que fazem parte da comunidade investigada. A escrita medeia um encontro entre a vida que está fora da escola e a vida que se faz dentro, estabelecendo determinadas funções para o letramento. Nessa escola, saber ler e escrever serve para: ser agricultor; ser cidadão do mundo; ser pesquisador. Além disso, constatamos que as crianças e os seus familiares são membros de um grupo social que usa a escrita de diferentes maneiras e para diversos propósitos em suas vidas e que as crianças acabam por se envolver em práticas de letramento ligadas ao mundo adulto, seja como participantes ou apenas observadores. Além disso, averiguamos que há uma relação complexa entre identidades social de gênero/ser agricultor e letramentos. O presente estudo pretende dar visibilidade às práticas de letramento dos membros e das crianças que vivem em uma comunidade rural em diferentes contextos, abrindo caminhos para que a instituição escolar reconheça e valorize o conhecimento que essas pessoas trazem para a escola, desconstruindo uma visão deficitária sobre populações rurais. / This study aims to describe the literacy orientations of children from first and third grades of an elementary public school located in a rural area in southern Brazil, as well as to investigate the presence and uses of writing at school, at home, and in other scenarios. The study involved nine months of ethnographic fieldwork, wtih participant observation, audiovisual recording of classroom settings, interviews with teachers and other members of the community, photographic records, and document collection. The entire theoretical investigative framework is based on the New Literacy Studies (HEATH, 1982.1983, 2012; STREET, 1984; BARTON, 2007), which understand literacy as a set of social practices involving reading and writing inscribed in a specific cultural context. The main concepts that guide this work are literacy (BARTON, HAMILTON, 1998), literacy events (HEATH, 1982) and practices of literacy (BARTON, 2007). From the data analysis, we could conclude that there is, in the school, literacy guidelines aligned with the promotion of a socially constructed knowledge, and it is directly connected to the socio-economic configuration of the groups who are part of the community. Writing mediates a connections between life that is out of school and life that happens inside of it, establishing determined functions for literacy. In this school, reading and writing are used to: be a farmer; be a citizen of the world; be a researcher. In addition, we found that children and their families are members of a social group that uses writing in different ways and for different purposes, as well as the children end up getting involved in literacy practices related to the adult world, either as participants or observers of them. Moreover, we found that there is a complex relationship between social identities of gender, the social identity of being a farmer, and literacies. This study aims to give visibility to the literacy practices of members and of children living in a rural community in different contexts, opening ways for the school institution to recognize and to value the knowledge that these people bring to school, deconstructing a deficit view of rural populations.

À partir du constat d’une absence d’apprentissage accusée de la part des élèves de français d’un collège insulaire grec, cette recherche tend à problématiser la relation qui existe entre la notion d’« apprenant » de français dans le Programme officiel et l’ « élève réel ». Le premier est constitué par le biais d’un discours disciplinaire revendiquant la modernisation du système éducatif par l’existence d’une dogmatique communicative : il s’agit d’un apprenant générique, entretenant une relation fonctionnelle avec la langue, actif dans son apprentissage, acteur dans toute situation de communication étrangère. Pour comprendre le deuxième, il faut l’observer en situation et dans ses interactions avec l’institution, il faut écouter sa parole : parole balbutiante d’un élève qui se cherche à la marge de l’apprentissage, parole d’un simulacre d’élève. Concevoir l’enseignement et l’apprentissage du français acquiert, dans ce contexte, des significations particulières. Le français, par sa qualité de langue « étrangère », pourrait constituer l’espace symbolique d’un devenir élève, d’un élève qui s’inscrit dans l’apprentissage par l’émergence de sa parole subjective. A condition que l’enseignant envisage l’élève au-delà de l’apprenant programmatique en s’impliquant lui même en tant que sujet dans la relation à tisser entre discours disciplinaire et pratiques de terrain. Assumer et exprimer le passage de la négativité de l’apprentissage de l’élève à l’émergence de l’apprenant réel marque sa prise en compte en tant que sujet par la pratique d’enseignement. / Deriving from the observation of an accentuated lack of learning of French as a Foreign Language in a secondary school in Greece, this research attempts to question the relation between the notions of “learner” in the official curriculum and the “real student”. Disciplinary discourse claiming modernisation of the educational system through a communicative doctrine construes the “learner” in generic terms as supposedly bearing a functional relationship with language, being an active participant and an actor in every communication situation. On the other hand, the “real student” can be comprehended through the observation of his acting and interacting with the institution and by listening to his words, those of a simulacrum of a student faltering in the margins of learning. In such a context, the process of teaching and learning French acquires particular significations. Due to its “foreignness”, the French language potentially constitutes a symbolic space for someone being a student, a student participating in the learning process through the emergence of his subjectivity in speech. On the condition that the teacher considers the student beyond the curriculum and by being involved himself as a subject in forming relations between the disciplinary discourse and classroom activities. To accept and to express the passage between the negativity of the student's learning and the emergence of a real learner marks the student’s consideration as being a subject in the process of teaching.

This study deals with an analysis of the contribution of a work-study practice for secondary vocational school students, especially in the area of social studies. It describes various forms of work-study practice at four high schools and evaluates the students' opinions regarding the value of work-study programs and their connection to classroom theory. The study seeks outputs for increasing the value of work-study programs so that the students would receive most practical expertise to work in their future occupations. It also brings arguments defending the continuation of the work-study programs in the secondary vocational school curriculae.

Résumé The presented work addresses the issue of the double-tracking nature of a dominant position in European competition law. The aim of the integration efforts during the establishment of the EU was the creation of an internal market, especially the customs union. In order to achieve this state, it was necessary to take a number of integration measures and create a legal framework, i.e. conditions, under which economic competition in the internal market could operate effectively. In this context a variety of legislation valid for the whole EU territory has been accepted. However, in the context of the economic competition this work analyzes the legislation on market dominance carried out first in Article 102 of TFEU (Treaty on the Functioning of the European Union) prohibiting restrictive business practices in the form of abuse of a dominant position and also in Council Regulation (EEC) No 4064/89 and later in Council Regulation (EC) No 139/2004 regulating the control of concentrations between undertakings. In case of both the legislations the crucial question is the "dominant position" of an enterprise in the market, while Article 102 of TFEU represents the ex post control, i.e. applies only to the possible abuse of the dominant position, and in this sense the dominant position itself is not the...

Este trabalho consiste em uma pesquisa acerca da análise do potencial heurístico resultado da não solução dos três problemas clássicos da matemática grega, via regra do uso exclusivo do compasso e da régua não graduada. Para uma melhor compreensão deste potencial, apresentaremos o histórico de tais problemas, fazendo posteriormente uma síntese geral sobre as principais concepções de filósofos e matemáticos sobre Heurística. Em seguida, demonstraremos algumas soluções alternativas para estes problemas, identificando nelas processos heurísticos. Finalmente introduziremos tais processos na resolução de problemas matemáticos, acompanhadas de possíveis implicações pedagógicas para o ensino dessa ciência. / This work consists of research about the potential of heuristic analysis result of no solution of the three classical problems of Greek mathematics, via rule of exclusive use of the compass and no graduated scale.
