O Caráter a priori das Estruturas Necessárias ao Conhecimento, Construídas segundo a Epistemologia Genética

In this paper we discuss the question of the a priori character of the necessary structures of knowledge according to Genetic Epistemology, focusing on the notion of space in particular. We establish some relations between Jean Piaget’s Genetic Epistemology and Immanuel Kant’s Critical Philosophy, discuss the notion of the a priori according to Kant in relation to the notion of space, and discuss the construction of the notion of space by the epistemic subject according to Genetic Epistemology, focusing on the Sensory-Motor Period. We conclude that, in Genetic Epistemology, space is still thought of as an a priori form of phenomena in the sense that the notion of space is what spatially organizes the data of perception, being the condition of perception. Furthermore, it is not directly abstracted from experience, but is constructed by the epistemic subject in its interaction with the environment, occurring with the structuring of the system of schemes of action. This analysis leads to the notion of the constructed a priori that, after its construction, has the characteristics of the a priori as conceived by Kant.

Contribuições na modelagem dinâmica e no controle neural de um braço robótico com elos flexíveis

Em geral, estruturas espaciais e manipuladores robóticos leves têm uma característica similar e inerente que é a flexibilidade. Esta característica torna a dinâmica do sistema muito mais complexa e com maiores dificuldades para a análise de estabilidade e controle. Então, braços robóticos bastantes leves, com velocidade elevada e potencia limitada devem considerar o controle de vibração causada pela flexibilidade. Por este motivo, uma estratégia de controle é desejada não somente para o controle do modo rígido mas também que seja capaz de controlar os modos de vibração do braço robótico flexível. Também, redes neurais artificiais (RNA) são identificadas como uma subespecialidade de inteligência artificial. Constituem atualmente uma teoria para o estudo de fenômenos complexos e representam uma nova ferramenta na tecnologia de processamento de informação, por possuírem características como processamento paralelo, capacidade de aprendizagem, mapeamento não-linear e capacidade de generalização. Assim, neste estudo utilizam-se RNA na identificação e controle do braço robótico com elos flexíveis. Esta tese apresenta a modelagem dinâmica de braços robóticos com elos flexíveis, 1D no plano horizontal e 2D no plano vertical com ação da gravidade, respectivamente. Modelos dinâmicos reduzidos são obtidos pelo formalismo de Newton-Euler, e utiliza-se o método dos elementos finitos (MEF) na discretização dos deslocamentos elásticos baseado na teoria elementar da viga. Além disso, duas estratégias de controle têm sido desenvolvidas com a finalidade de eliminar as vibrações devido à flexibilidade do braço robótico com elos flexíveis. Primeiro, utilizase um controlador neural feedforward (NFF) na obtenção da dinâmica inversa do braço robótico flexível e o calculo do torque da junta. E segundo, para obter precisão no posicionamento... (Resumo completo, clicar acesso eletrônico abaixo)

Deslocamento de caráter em hilídeos neotropicais (anura: hylidae)

The interspecific competition tends to favor the selection of divergent phenotypes minimizing the effect of this interaction. This process is termed character displacement and it is considered one of the main mechanisms promoting adaptive diversification. Brazil has the greatest diversity of amphibians on the planet and despite this great diversity; the role of character displacement in the process of Brazilian amphibian fauna diversification has not been studied. In the present study we tested the hypothesis of character displacement in four congeneric species pairs of frogs from the family Hylidae, occurring in the Atlantic Forest and Cerrado. We find evidence of character displacement for two pairs and parallel evolution for the remaining. Interestingly, the trend of character displacement was in species whose range covers less stable habitats. Since this is a pioneering study with neotropical hylid, we discussed issues considered relevant to elucidate mechanisms related to the maintenance of diversity

No resumo de um só dia: tempo e memória em O burrinho pedrês de Gumarães Rosa

Memory, the ability of keeping and remembering past states of consciousness and everything that could be associated with them, is one of the human properties responsible for the construction of experience, knowledge and preservation of individual’s identity. However, recalling is also the way we keep relationships with time, factor that is essential and inherent to our existence and responsible for the fact that we have memory. As for the narrative, as for life, time is a prime category, because it is in time that narrated or experienced events happen. This relationship between time and memory is remarkable in “O burrinho pedrês”, Guimarães Rosa’s short story present in his debut book, Sagarana. In this story, we can notice, generally, the characters use memory as a way to return to the past, evoking, consciously or unconsciously, the experience and its result, the wisdom, to help on the understanding of present situations. So, this research has as objective to analyze how time and memory relate and become indispensable to the development of the narrative and to the construction of the other categories - character, narrator and space. The theoretical foundation is based on studies clustered in three dimensions: a) theoretical essays about Guimarães Rosa’s work in general and the particular short story b) philosophical and/or psychological propositions about memory and time, and c) propositions about the mentioned categories of narrative

Aforização no discurso de autoajuda

In this paper, based on Maingueneau’s (2006, 2010) thoughts on aphorisation and on the differences between aphorising and textual enunciation, we analyze some detached utterances from the self-help discourse, by highlighting some of their meaning effects and their role in such discourse. The analysis shows that the aphorising detachments support the self-help discourse enunciator in the process of guiding the interlocutors. Such aphorizing detachments allow the enunciator to give order as if he or she were enunciating the truth, which attenuates the enunciator’s authoritative character, who is supposed to give order explicitly. Moreover, such utterances activate the play between “to say and not to say,” by simulating that the self-help discourse is based on an undeniable truth, which reinforces its persuasive power.

O olhar revolucionário em As Meninas

We analyzed here, Lia de Melo Shultz, one of the protagonists of As meninas, Lygia Fagundes Telles. Incarnation of the revolutionary romanticism of 60- 70 years of the century XX, she is the most representative character of a double crisis: the political authoritarianism of the military dictatorship and patriarchy. We highlight of the characteristic features of narrative character, exploring their actions and ideas and their role in the dramatic conflict. To contextualize the fable, we make use of texts Boris Fausto, Nadine Habert, Elio Gaspari and Leonardo Pinheiro.

A Faculdade de Filosofia, Ciências e Letras de São José do Rio Preto no período de 1957 a 1964: estudo de uma instituição escolar

According to the existing literature, the FFCL of São José do Rio Preto had a pioneering role as regards the organization and management of higher education. This article aims to discuss the originality/innovativeness of the educational project of this institution in the period from 1957 to 1964, based on an analysis of departmental organization and student participation. In order to do so, we use documents about the creation process of the FFCL, reports of courses, and minutes of departmental meetings and of the Academic Philosophical Center. The results show that, indeed, this institution was organized in three departments, though these operated in consonance with the chair system. Student participation varied from equal representation to the representation of a single student per class. Thus, the results show that the innovative/revolutionary character of this institution was exaggerated in the existing literature and may have contributed to the existing “mysticism” in the city as regards the history and the importance of this institution.

O Ensaísmo na Historiografia Brasileira

In this paper we analyze the question of character essayistic the historiography of the first half of the twentieth century. We examined this issue due to the emergence of a new trend on the historiographical colonization (School of Rio) who criticizes, among other things, the essay-like character in historiography. Whereas the criticism expressed how a new trend breaks with the existing historiography, we decided to examine this critical gauge. To promote the overcoming of a certain history is necessary to understand it in its historicity, that is, the motivations that led historians to examine the history of a given way. Of course, criticism is a moment of transcendence. But to be a radical departure is necessary to understand the historiography of historical criticism and not simply point their supposed mistakes, shortcomings and failures.

Pure spinor partition function using Padé approximants

In a recent paper, the partition function (character) of ten-dimensional pure spinor worldsheet variables was calculated explicitly up to the fifth mass-level. In this letter, we propose a novel application of Padé approximants as a tool for computing the character of pure spinors. We get results up to the twelfth mass-level. This work is a first step towards an explicit construction of the complete pure spinor partition function.

Discurso e história: representações do feminino em Ana Bolena

The central theme of this work is the construction of the identity of the female gender in the light of discourse analysis. To achieve this goal we used three different media productions made during the twentieth and twenty-first century that address the same historical character: Anne Boleyn, the second wife of Henry VIII. From the research and analysis of images carefully selected to represent three different real moments of Anne Boleyn, it was possible to realize how the same scene may have different approaches and how such approaches are influenced not only by the author of the work, but also by a discursive game that coordinates what can or can't be said by a society. The study concludes that the discourse analysis, besides assisting in the understanding of life and speeches of the historical character in question, also provides subsidies to know the society not only at the time that Anne Boleyn lived, but also at the time when the media productions studied here were performed
