À procura de (nossas próprias) palavras: filosofia e subjetividade

Writing about philosophical practice with children requires a memory of the body, a body that holds on to what is important to itself. My memory begins with my contact with the ideas of Matthew Lipman and the new ideas brought by his words, and continues with the need to change some of them and assign different meanings to others. Since my reading of the thinkers of the so called “Frankfurt School,” some words have taken new meanings to me, and have informed the way I now understand the practice of philosophy with children and its relationship to issues like educational “formation,” as well as others. Philosophical practice is unique, and needs to be thought, felt, and experienced; it has its own time and involves the construction and transformation of subjectivity itself. As such, to search for words in philosophy means to chose those words that can help us make sense and give meaning of what we do and think, allowing us to work with our thinking and with its forms of expression, beyond its technical dimension. In this sense, the usual emphasis of philosophy in its more technical dimension leads to an impoverishment of formation as experience, for the latter, which is a fundamental dimension of our lives, is rendered secondary. This has implications for the relationship between adults and children. When they reduce philosophy to a study of the formal capacity of thinking, teachers put students in the condition of a minority, and therefore in some way also put themselves in such a condition. In this paper, the activity of writing - as a way of expressing thought - allows me to conduct a tour my own subjectivity, and to encounter the words that express the meanings that inform what I think and do about my practice with philosophical novels, and about the value of generating texts related to philosophical practice, formation and assessment.

Os rapazes da Rua Panisperna e os centomila Majorana: os fatos e as versões literária e audiovisual

While a certain novel ponders about the traces left by Ettore Majorana and expounds some theories about the fate of the character mysteriously disappeared, a movie by Gianni Amelio also inspirited by facts goes through another path, of the story of Via Panisperna boys, stressing the enigmatic figure of Ettore Majorana and the exciting episodes surrounding some of the greatest physicists of the world. When Leonardo Sciascia publishes the novel in which he uses the actual fact of Ettore Majorana’s disappearance in order to create what he calls a “philosophical novel of mystery”, the public had already probably forgotten the intriguing events of 1938: the young and bright physicist disappeared, by all accounts, voluntarily, without leaving proofs of his death or reliable evidence of his whereabouts. In 1972, Sciascia learns about mysterious clues by means of Erasmo Recami and considers the motives that could have made Majorana leave Italy and later abandon his life almost in the mode fictionalized by Pirandello.

Future(s) Perfect: uchronian mapping as a research and visualisation tool in the fringes of the Olympic Park

This article explores and discusses the development of a mapping tool inspired by Charles Renouvier’s philosophical novel Uchronie (l’utopie dans l’histoire) (1876). The article explains the research and design process of creating a uchronian map of a formerly empty site in Fish Island in East London and describes a participatory workshop titled ‘Hackney Wick and Fish Island: Future Perfect(s)’ (25 April 2015) that used uchronian mapping to explore past and future development imaginaries of two sites in the neighbourhood. Given a uchronian mapping template, a protocol and a dossier of planning and other documents, participants were encouraged to develop their own uchronian map of each site, and in doing so test and question the process of visualizing ‘what was supposed to happen’, ‘what actually happened’ and ‘what could have happened’. The article concludes with a reflection on uchronian mapping as a tool for researching, analysing and making visible urban alternatives.

Fabrication of novel light-emitting devices based on green-phosphor/conductive-polymer composites

We report on light-emitting devices based on a green-phosphor compound (Mn-doped zinc silicate, Zn2SiO4: Mn) dispersed in a conductive polymeric blend (poly-o-methoxyaniline/polyvinylene fluoride, POMA/PVDF-TrFE). The devices exhibited high luminance in the green, good stability and homogeneous brilliance over effective areas up to 5 cm(2). The electroluminescence (EL) spectrum presented essentially the same characteristics as the photoluminescence (PL) and cathodoluminescence spectra, indicating that the light emission originates from decay of the same excited species, regardless of the excitation source. Operating characteristics were analyzed with current density - voltage (J - V) and luminance voltage ( L - V) curves to investigate the nature of the electroluminescence of the active material, which is still not completely understood.

A Novel Range Test

In a range test, one party holds a ciphertext and needs to test whether the message encrypted in the ciphertext is within a certain interval range. In this paper, a range test protocol is proposed, where the party holding the ciphertext asks another party holding the private key of the encryption algorithm to help him. These two parties run the protocol to implement the test. The test returns TRUE if and only if the encrypted message is within the certain interval range. If the two parties do not conspire, no information about the encrypted message is revealed from the test except what can be deduced from the test result. Advantages of the new protocol over the existing related techniques are that it achieves correctness, soundness, °exibility, high e±ciency and privacy simultaneously.
