This paper presents the contributions of Alcindo Flores Cabral, professor of Chemistry at the Faculdade de Agronomia Eliseu Maciel, nowadays part of the Universidade Federal de Pelotas, to chemistry teaching. It is a contribution almost unknown to the Brazilian chemical community, although recognized as valuable by several renowned chemists abroad, like W. Hückel, G. Charlot, F. Strong, E. Fessenden and others. Cabral’s innovative helical representation is presented in connection not only with contemporary representations, but also an incursion is made into (...) the first helical systems proposed, those of Hinrichs and of Baumhauer. Some comments are made not only on Cabral’s Classificação Natural dos Elementos, published in 1946, but also about other texts he wrote for an efficient chemistry teaching. (shrink)

Este artigo apresenta a contribuição de Alcindo Flores Cabral (1907-1982) - professor de química da Faculdade de Agronomia Eliseu Maciel, hoje incorporada à Universidade Federal de Pelotas - ao ensino de química, uma contribuição quase desconhecida pela própria comunidade química brasileira, embora reconhecida como relevante por diversos químicos estrangeiros importantes, como W. Hückel, G. Charlot, F. Strong, E. Fessenden e outros. A inovadora representação helicoidal de Cabral é apresentada não só em conexão com representações contemporâneas, mas também inclui-se uma incursão (...) pelos primeiros sistemas helicoidais propostos, os de Hinrichs e de Baumhauer. Apresentam-se alguns comentários não somente sobre a Classificação natural dos elementos, publicada em 1946, mas também sobre outros textos escritos para tornar mais eficaz o ensino de química.

O presente trabalho examina os aspectos históricos da extração do óleo de canela-sassafrás (Ocotea pretiosa Mez), rico em safrol, no Alto e Médio Vale do Itajaí, a partir de 1940, por iniciativa de Otto Grimm, no município de Rio do Sul. Apresenta-se o tema no contexto da memória química em Santa Catarina, e discutem-se os procedimentos utilizados, e principalmente os motivos que levaram tal indústria incipiente a não se converter em uma indústria de química fina. Para tanto, são apresentados alguns (...) dados pertinentes à química do safrol, indicando que tal indústria poderia ter evoluído, bem como os aspectos econômicos e sociais que, ao lado da proibição do corte da canela-sassafrás, levaram em 1990 à extinção definitiva dessa "química fina que poderia ter sido".

Dos diferentes fatores associados a uma mudança de paradigma e, portanto, a uma revolução química, o menos discutido é o que envolve os assim chamados experimentos exemplares, mudanças radicais na metodologia de trabalho e nos procedimentos empíricos da química, mudanças e modificações estas que, no caso de uma ciência natural empírica, podem ter como consequência dados experimentais antes inacessíveis, levando, por fim, a uma nova abordagem de conceitos, hipóteses e teorias e desencadeando uma "revolução" química, um novo paradigma. Muito mais (...) do que uma revolução química, dever-se-ia optar por uma gradativa evolução química. Escolhemos três dessas situações como "exemplares": a modificação no procedimento empírico da química pneumática, com o uso da cuba pneumática contendo mercúrio; a introdução de novos métodos de extração de compostos orgânicos naturais, com a substituição do método pirogênico pelo de extração com solventes; um novo entendimento de "análise química", com a substituição da comparação de amostras tidas como autênticas pela decomposição do analito.

Scientific policy advice is usually perceived as a formalized advisory process within political institutions. Politics has benefited from this arrangement because the science-based rationalization of policy has contributed to its legitimacy. However, in Western democratic societies, scientific expertise that is routinely mobilized to legitimate political positions has increasingly lost its power due to controversial expertise in the public sphere in particular within the mass media. As a consequence of the medialization of science, political decision makers are increasingly confronted with mass-mediated (...) expertise. Empirical results of a qualitative survey among decision makers in the German political and administrative system, presented in this article, support the hypothesis that mass-mediated expertise has a significant impact on policy processes. Five functions of media coverage on science-based issues for policy making were identified. Mass-mediated expertise has therefore altered the established relations between scientific policy advisors and political decision makers and can be seen as informal policy advice complementing institutionalized advisory arrangements.

Aus ganz unterschiedlichen Blickwinkeln, sei es aus musikhistorischer oder ethnomusikologischer Sicht, umkreisen zehn Beitrage das Thema aMusik - Zu Begriff und Konzepteno. Unter dieses Thema ein internationales Symposion in Berlin zu stellen, das zum Gedenken an Hans Heinrich Eggebrecht (1919-1999) veranstaltet wurde, erschien umso naheliegender, zumal Eggebrecht die Frage aWas ist Musik'o existenziell beruhrte, sie grundierte und sein Forscherleben als Musikwissenschaftler von den fruhen Veroffentlichungen nach dem Zweiten Weltkrieg bis zu den letzten Arbeiten durchzog. Inhalt Bruno Nettl: Was ist (...) Musik? Ethnomusikologische Perspektive Sabine Ehrmann-Herfort: Die Kantate. Musik zwischen asthetischer Autonomie und Ideologie Christian Berger: aMusiko nach Kant Erich Reimer: aMusikanto und aMusiko.

Understanding Music summarizes Eggebrecht's thoughts on the relationship between music and cognition.

"L'un des aspects les plus intrigants de l'œuvre de Michel Foucault réside dans son intérêt tardif pour la pensée antique, plus spécialement pour la culture grecque et son héritage romain qu'on peut faire remonter à ses recherches ayant mené, à partir de 1976, à son Histoire de la sexualité. Du fait même de l'infléchissement que connut alors sa pensée, Foucault fut à même d'établir des liens à tous égards originaux et même surprenants entre la pensée antique et la réflexion moderne. (...) En le lisant, c'est une tradition de près de 2500 ans qui s'offre désormais à notre regard. Que nous apprend, sur notre histoire, le fait de mettre en parallèle les propos de Socrate et ceux de Kant? À quoi peut servir l'interrogation menée sur la sexualité antique, si ce n'est peut-être à la « dépsychologiser », la « dépathologiser », la « détaxonomiser », et ainsi la « désenclaver » de ses classifications ultérieures? Que nous enseigne le fait d'entendre par « modernité » non plus une « époque » particulière de l'histoire, mais une manière d'être des individus, une certaine attitude adoptée, « ce que les Grecs, souligne Foucault, appelaient un ' éthos ' »? De quelle manière, finalement, l'esprit critique moderne s'éclaire-t-il de l'esprit critique antique? Les études ici rassemblées posent ces questions à Foucault, avec Foucault et parfois aussi contre Foucault, en écho toujours à ce « courage de la vérité » dont il incarna si splendidement l'exemple."--Page 4 de la couverture.

Inspite of growing interest in research on language universals the concept of language universal itself has not been clarified beyond its status in Greenberg 1966. The present paper is an attempt at further clarification. The concept of language universal presents at least the following basic problems : Which entities are to be called universal? How can universality statements be deductively related to statements on individual languages and to non-linguistic statements, e.g. psychological ones? How are we to conceive the relation between (...) the 'empirical' and the 'non-empirical' in universality research? It is argued that the universal entities should be properties of languages. Three conceptions of universals are characterized: The Naive View , the Semantic View , and the Pragmatic View proposed by the author . It is argued that the Naive View and the Semantic View do not, and that the Pragmatic View may solve the basic problems formulated in Part I. Combining the Pragmatic View with the conception of theories developed in Lieb to appear the author characterizes the ultimate aim of universality research as defining a set of properties that, if taken as universal by any linguist, maximize the fruitfulness of any theory of language. The main task of universality research consists in making universality proposals that are well-founded with respect to that aim. Various principles are suggested by which the well-foundedness of universality proposals can be judged. (shrink)

A series of dialogues with the most exciting and controversial German philosopher writing today. Peter Sloterdijk first became known in this country for his late 1980s Critique of Cynical Reason, which confronted headlong the “enlightened false consciousness” of Habermasian critical theory. Two decades later, after spending seven years in India studying Eastern philosophy, he is now attracting renewed interest for his writings on politics and globalization and for his magnum opus Spheres, a three-volume archaeology of the human attempt to dwell (...) within spaces, from womb to globe: Bubbles, 1998; Globes, 1999; Foam, 2004, all forthcoming from Semiotext. In Neither Sun nor Death, Sloterdijk answers questions posed by German writer Hans-Jürgen Heinrichs, commenting on such issues as technological mutation, development media, communication technologies, and his own intellectual itinerary. Iconoclastic and provocative, alternatively sparkling and bombastic, a child of '68 and a libertarian, Sloterdijk is the most exciting and controversial German philosopher to appear on the world scene since Nietzsche and Heidegger. Like Nietzsche, Sloterdijk remains convinced that contemporary philosophers have to think dangerously and let themselves be “kidnapped” by contemporary “hypercomplexities”; they must forsake our present humanist and nationalist world for a wider horizon at once ecological and global. Neither Sun nor Death is the best introduction available to Sloterdijk's philosophical theory of globalization. It reveals a philosophe extraordinaire, encyclopedic and provocative, as much at ease with current French Theory as with Heidegger and Indian mystic Osho Rajneesh. (shrink)

Neuroenhancement involves the use of neurotechnologies to improve cognitive, affective or behavioural functioning, where these are not judged to be clinically impaired. Questions about enhancement have become one of the key topics of neuroethics over the past decade. The current study draws on in-depth public engagement activities in ten European countries giving a bottom-up perspective on the ethics and desirability of enhancement. This informed the design of an online contrastive vignette experiment that was administered to representative samples of 1000 respondents (...) in the ten countries and the United States. The experiment investigated how the gender of the protagonist, his or her level of performance, the efficacy of the enhancer and the mode of enhancement affected support for neuroenhancement in both educational and employment contexts. Of these, higher efficacy and lower performance were found to increase willingness to support enhancement. A series of commonly articulated claims about the individual and societal dimensions of neuroenhancement were derived from the public engagement activities. Underlying these claims, multivariate analysis identified two social values. The Societal/Protective highlights counter normative consequences and opposes the use enhancers. The Individual/Proactionary highlights opportunities and supports use. For most respondents these values are not mutually exclusive. This suggests that for many neuroenhancement is viewed simultaneously as a source of both promise and concern. (shrink)

Overtreatment is when medical or dental services are provided with a higher volume or cost than is appropriate. This study aimed to investigate how a group of dentists in Switzerland, a wealthy country known to have high standards of healthcare including dentistry, evaluated the meaning of unnecessary treatments from an ethical perspective and, assessed the expected frequency of different possible behaviors among their peers.

Die Themen Kreativität, Selbsttranszendenz und Gewalt erzeugen in der Forschung des Soziologen und Sozialphilosophen Hans Joas eine Spannung, aus der ein kreativer und eigener Denkansatz in der deutschen Sozialwissenschaft entstanden ist. Er schöpft aus der Quelle einer langjährigen Auseinandersetzung mit dem US-amerikanischen Pragmatismus und seiner Betonung der Bedeutung menschlicher Handlungen. Daraus hat Joas eine eigene Position zur Entstehung von Werten und Normen entwickelt. Seine neueren Forschungen zur Entstehung der Menschenrechte als einem Prozess der Verarbeitung von Gewalterfahrung sowie der Sakralisierung (...) der Person setzen dieses Programm konsequent fort.

Johann Heinrich Lambert (1728–1777) galt schon den Zeitgenossen als Universalgenie von europäischem Rang. Tatsächlich forschte und publizierte Lambert als Mathematiker und Philosoph, und zwar vor allem zur Logik und Metaphysik, zur Erkenntnis- und Sprachtheorie, als Astronom und Physiker. Seinem Aufklärungsverständnis gemäß wirkte er nicht nur mit einer Vielzahl von Publikationen in die Wissenschaften, sondern als Popularphilosoph darüber hinaus auch in die sich ent- wickelnde Gesellschaft und den Staat der Aufklärung hinein. Dass Lambert vor dem Hintergrund dieses Selbstverständnisses als Aufklärer auch (...) Gedichte verfasste, überrascht dabei nicht. Der Band versammelt erstmals Studien zu allen Werkteilen des Berliner Gelehrten. (shrink)
