Ce texte reprend une conférence faite par H.-J. Wirth à Washington (États-Unis) en octobre 2005. Ces réflexions pourraient facilement se transposer sur la relation entre le thérapeute et le patient ; de la même façon, elle se caractérise par des positions de pouvoir différentes. Jurg Willy, se référant à Dicks et à son concept de collusion dans le cadre de la thérapie de couple, en a élargi la formulation dans la mesure où il a placé les attentes inconscientes, réciproques (...) et le jeu inconscient des deux partenaires, au centre de sa réflexion.

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.

This article sketches an idealized strategy for the identification of neural correlates of consciousness. The proposed strategy is based on a state space approach originating from the analysis of dynamical systems. The article then focuses on one constituent of consciousness, phenomenal awareness. Several rudimentary requirements for the identification of neural correlates of phenomenal awareness are suggested. These requirements are related to empirical data on selective attention, on completely intrinsic selection and on globally unconscious states. As an example, neuroscientific findings on (...) synchronized γ activity are categorized according to these requirements. (shrink)

Philosophical discussions on causal inference in medicine are stuck in dyadic camps, each defending one kind of evidence or method rather than another as best support for causal hypotheses. Whereas Evidence Based Medicine advocates the use of Randomised Controlled Trials and systematic reviews of RCTs as gold standard, philosophers of science emphasise the importance of mechanisms and their distinctive informational contribution to causal inference and assessment. Some have suggested the adoption of a pluralistic approach to causal inference, and an inductive (...) rather than hypothetico-deductive inferential paradigm. However, these proposals deliver no clear guidelines about how such plurality of evidence sources should jointly justify hypotheses of causal associations. We here develop such guidelines by first giving a philosophical analysis of the underpinnings of Hill’s viewpoints on causality. We then put forward an evidence-amalgamation framework adopting a Bayesian net approach to model causal inference in pharmacology for the assessment of harms. Our framework accommodates a number of intuitions already expressed in the literature concerning the EBM vs. pluralist debate on causal inference, evidence hierarchies, causal holism, relevance, and reliability.

Narrative allegory is distinguished from mythology as reality from symbol; it is, in short, the proper intermedium between person and personification. Where it is too strongly individualized, it ceases to be allegory […]. In the community of scholars of intermedia research, the above quoted citation is commonly regarded as Coleridge’s coining of the term “intermedium” or “intermediality”. However, a short glance at the discursive strategy of his argument emphasizes that his notion of “intermedium” must be closely linked to the poetics (...) and aesthetics of 19th-century romanticism. For the romantic poet, the term of “intermedium” does not point to media relations or intermedia processes but to.. (shrink)

According to the objective Bayesian approach to inductive logic, premisses inductively entail a conclusion just when every probability function with maximal entropy, from all those that satisfy the premisses, satisfies the conclusion. When premisses and conclusion are constraints on probabilities of sentences of a first-order predicate language, however, it is by no means obvious how to determine these maximal entropy functions. This paper makes progress on the problem in the following ways. Firstly, we introduce the concept of a limit in (...) entropy and show that, if the set of probability functions satisfying the premisses contains a limit in entropy, then this limit point is unique and is the maximal entropy probability function. Next, we turn to the special case in which the premisses are categorical sentences of the logical language. We show that if the uniform probability function gives the premisses positive probability, then the maximal entropy function can be found by simply conditionalising this uniform prior on the premisses. We generalise our results to demonstrate agreement between the maximal entropy approach and Jeffrey conditionalisation in the case in which there is a single premiss that specifies the probability of a sentence of the language. We show that, after learning such a premiss, certain inferences are preserved, namely inferences to inductive tautologies. Finally, we consider potential pathologies of the approach: we explore the extent to which the maximal entropy approach is invariant under permutations of the constants of the language, and we discuss some cases in which there is no maximal entropy probability function.

We study questionnaire responses to situations in which sacrificing one life may save many other lives. We demonstrate gender differences in moral judgments: males are more supportive of the sacrifice than females. We investigate a source of the endorsement of the sacrifice: antisocial preferences. First, we measure individual proneness to spiteful behavior, using an experimental game with monetary stakes. We demonstrate that spitefulness can be sizable—a fifth of our participants behave spitefully—but it is not associated with gender. Second, we find (...) that gender is consistently associated with responses even when we account for individual differences in the propensity to spitefulness. (shrink)

In this essay, we aim to provide an overview of the periodic table’s origins and history, and of the elements which conspired to make it chemistry’s most recognisable icon. We pay attention to Mendeleev’s role in the development of a system for organising the elements and chemical knowledge while facilitating the teaching of chemistry. We look at how the reception of the table in different chemical communities was dependent on the local scientific, cultural and political context, but argue that its (...) eventual universal acceptance is due to its unique ability to accommodate possessed knowledge while enabling novel predictions. Furthermore, we argue that its capacity to unify apparently disconnected phenomena under a simple framework facilitates our understanding of periodicity, making the table an icon of aesthetic value, and an object of philosophical inquiry. Finally, we briefly explore the table’s iconicity throughout its representations in pop art and science fiction. (shrink)

Augmented Reality (AR) is commonly defined as a digital layer of information viewed on top of the physical world through a smartphone, tablet or eyewear. Increasingly, this understanding of AR is shifting to a dynamic framework of ‘smart things’, including wearable technology, sensors and artificial intelligence (AI), with the ability to intercede in key moments and to deliver contextual and meaningful experiences. The things that come into context are the logical next steps in an evolutionary development towards computers that are (...) better able to show empathy in relation to people: even more human-oriented, anticipative and ubiquitous. Thus, this outsourcing of meaning to empathic technologies points to one of the fundamental questions concerning the relation of human and technology – the nature of the trust that users place in technology.

Epistemic scoring rules are the en vogue tool for justifications of the probability norm and further norms of rational belief formation. They are different in kind and application from statistical scoring rules from which they arose. In the first part of the paper I argue that statistical scoring rules, properly understood, are in principle better suited to justify the probability norm than their epistemic brethren. Furthermore, I give a justification of the probability norm applying statistical scoring rules. In the second (...) part of the paper I give a variety of justifications of norms for rational belief formation employing statistical scoring rules. Furthermore, general properties of statistical scoring rules are investigated. Epistemic scoring rules feature as a useful technical tool for constructing statistical scoring rules. (shrink)

On the True Sense of Art collects essays by philosophers responding to John Sallis's Transfigurements: On the True Sense of Art as well as his other works on the philosophy of art, including Force of Imagination and Logic of Imagination. Each of the chapters, by some of the leading thinkers in Continental philosophy, engages Sallis's work on both ancient and new senses of aesthetics--a transfiguration of aesthetics--as a beginning that is always beginning again. With a responsive essay by Sallis himself, (...) On the True Sense of Art forms a critical introduction to the thought of this generation's most important aesthetician. (shrink)

2015 Reprint of Original 1936 American Edition. Exact facsimile of the original edition, not reproduced with Optical Recognition Software. Karl Mannheim was a Hungarian-born sociologist, influential in the first half of the 20th century and one of the founding fathers of classical sociology as well as a founder of the sociology of knowledge. His essays on the sociology of knowledge have become classics in the field. In "Ideology and Utopia" he argued that the application of the term ideology ought to (...) be broadened. He traced the history of the term from what he called a "particular" view. This view originally saw ideology as the perhaps deliberate obscuring of facts. Over time this view gave way to a "total" conception (most notably in Marx), which argued that a whole social group's thought was formed by its social position (e.g. the proletariat's beliefs were conditioned by their relationship to the means of production). However, he called for a further step, which he called a general total conception of ideology, in which it was recognized that everyone's beliefs-including the social scientist's-were a product of the context they were created in. Mannheim points out social class, location and generation as the greatest determinants of knowledge. He feared this could lead to relativism but proposed the idea of relationism as an antidote. To uphold the distinction, he maintained that the recognition of different perspectives according to differences in time and social location appears arbitrary only to an abstract and disembodied theory of knowledge.

As digital media becomes more central to the lives of adolescents, it also becomes increasingly relevant for their sexual communication. Sexting as an important image-based digital medium provides opportunities for self-determined digital communication, but also carries specific risks for boundary violations. Accordingly, sexting is understood either as an everyday, or as risky and deviant behavior among adolescents. In the affectedness of boundary violations gender plays an important role. However, it is still unclear to what extent digital sexual communication restores stereotypical (...) gender roles and restrictive sexuality norms or, alternatively, enables new spaces of possibility. In this sense, current research points to a desideratum regarding adolescents’ orientations toward sexting as a practice between spaces of possibility and boundary violations. This paper discusses the possibilities, but also the risks, of intimate digital communication among adolescents. The main question is, how adolescents themselves perceive sexting practices and how they position themselves between both spaces for possibility and for the exchange of unwanted sexual content. For this purpose, orientations toward normalities and gender of students are reconstructed. To answer these questions, twelve single-sex, group discussions were carried out with students aged 16 and 17 at five different secondary schools in northern Germany. A total of 20 boys and 22 girls took part. The group discussions were structured by a narrative generating guideline. The analysis draws its methodology from the Documentary Method, regarding implicit and explicit forms of knowledge and discourse. It results in a typology of three types with different orientations. The study shows, that most of the students consider sexting to be a risky practice; only one type shows normality in the use of sexting. At the same time, some of the young people are interested in experimenting with image-based intimate digital communication. Further, gender differences in use and affectedness are also documented. In this way, orientations toward gender stereotypes “favor” both the attribution of responsibility to girls, and overlook the responsibility of students who perpetrated the boundary violation. The orientations of adolescents should be taken more into account in research as well as in educational programs for the prevention of sexual violence. (shrink)

Beherrschten vor 20 Jahren noch Industriekonglomerate, Energiekonzerne und Banken die Rangliste der wertvollsten Unternehmen, wurden diese längst von Internetgiganten wie Google, Apple, Amazon und Tencent abgelöst. Digitale Technik ist allgegenwärtig: Wir tragen Hochleistungsrechner in unseren Taschen herum, Waschmaschinen können sich mit dem Internet verbinden. Doch erschöpft sich darin das Neue am digitalen Kapitalismus? 0Philipp Staab beleuchtet den digitalen Kapitalismus aus unterschiedlichen Perspektiven, um ihn präziser auf den Begriff zu bringen. Er zeigt, wie digitale Überwachungs- und Bewertungspraktiken in immer mehr Bereiche (...) der Wirtschaft vordringen und dabei die soziale Ungleichheit verschärfen. Das Spezifische am digitalen Kapitalismus, so Staab, ist die Herausbildung 'proprietärer Märkte': Kam es früher darauf an, Dinge herzustellen und mit Gewinn zu verkaufen, geht es im Zeitalter der Unknappheit um das Eigentum an den Märkten selbst.

ÖZ “Tanzanya’da Leibzig Misyoner Cemiyeti Misyonerliği, Karşılaşılan Zorluklar ve Kullanılan Yöntemler” isimli makale “Tanzanya’da Misyonerlik Faaliyetler Lutheran Kilise Örneği” isimli yüksek lisans tezine dayanmaktadır. Makale, Lutheran misyonerliğinin Tanzanya’da faaliyetlerine nasıl başladıkları, ilerleme yöntemleri ve karşılaşılan güçlükleri anlama noktasında önem arz etmektedir. Makalede ana konuya odaklanmadan önce, Tanzanya hakkında genel bir bilgilendirme yapılmış, ardından Leibzig Misyon Cemiyeti’nin (LMS) faaliyetlerine nasıl başladığı, kronolojik bir şekilde açmış olduğu istasyonlar, bu istasyonlarda karşılaşmış olduğu zorluklar ve kullanılan yöntemler hakkında bilgi verilmiştir. Ayrıca, Tanzanya’da Lutheran misyoner (...) cemiyetlerinin, Tanzanya Evanjelik Lutheran Kilisesi (Tanzania Evangelical Lutheran Church in Tanzania) ELCT ile tek bir kilise çatı altında toplanması ele alınmıştır. Son olarak, ELCT’nin kabul etmiş olduğu ilkeler ve Martin Luther’in öğretilerinin Afrika’daki yansımaları üzerinde durulmuştur. Makale, sadece misyonerleri ve misyonerlik faaliyetlerini değil, ayrıca muhatap olunan ve yüzyıllardır sömürgeleştirilen Afrika halkını anlamamıza da yardımcı olmaktadır. Araştırma, Lutheran misyonerliğinin Tanzanya’da başlamış olduğu 19. yüzyıl sonu ve yoğunlaştığı 20. yüzyıl ile sınırlandırılmıştır. Otto von Bismarck’ın (1815-1898) katkılarıyla gerçekleşen Berlin Konferansı sayesinde, batılı ülkelerin bayrakları ile haçları da sömürge topraklarına girmiştir. Tanzanya'da Lutheran Misyon, Johann Ludwig Krapf (1810-1881) ve Johannes Rebmann'ın (1820-1876) CMS tarafından görevlendirilmeleri sonucu başlamıştır. LMS, CMS'den 1892 tarihinde görevi devralmıştır ve Machame, Mamba, Old Moshi, Pare, Meru'da faaliyet göstermiştir. Misyon faaliyetleri süresince, savaşlar, kıtlık ve salgın, çok eşlilik, sünnet uygulaması, tanrı anlayışı gibi birçok zorlukla karşılaşılmıştır. Zorluklar, onları ortadan kaldırmaya yardımcı olacak; eğitim, sağlık, bütüncül hizmet, ortak dil (lingua franca), Kutsal Kitap çevirileri, ev ziyaretleri, yerli yardımcılar ve yerlileştirme gibi yöntemleri de beraberinde getirmiştir. Tanzanya’da LMS dışında; Katolik Kutsal Ruh Babaları (Holy Ghost Father/ Spiritanlar), Katolik Beyaz Babalar (Peres Blancs), Katolik Benediktinler, Anglikan Kilise Misyon Topluluğu (Chuch Missionary Society) CMS, Anglikan Üniversitelerin Orta Afrika Misyonu (The Universities’ Mission to Central Africa) UMCA gibi misyon grupları mevcuttur. Tanzanya'da bulunan Lutheran Misyon toplulukları, Evanjelik Lüteriyen Kilisesi (ELCT) adı altında 1963 yılında tek bir çatı altında toplanmıştır. ELCT bugün 5,2 milyon üyesi ile Tanzanya nüfusu içinde hatırı sayılır bir yere sahiptir. Bu çalışmada, deskriptif yöntem kullanılmıştır. Ulaşılabilen tüm ilk kaynaklara inilerek Lutheran misyonerler ve Tanzanya hakkında bilgi verilmiştir. Çalışmada Türkçe kaynaklara yer verilmekle birlikte yabancı kaynak kullanımına ve misyon topluluklarının bilinen kısaltmalarının kullanılmasına önem gösterilmiştir. Anahtar Kelimeler; Tanzanya, Hıristiyanlık, Misyonerlik, Lutheranizm, Leipzig Misyon Cemiyeti. (shrink)

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.

The chemist Max von Pettenkofer studied with Justus von Liebig, and after leaving Giessen in 1844 did not immediately find an academic position. During the period 1844/1845 he wrote a cycle of 16 Chemical Sonnets, but published them only in 1886. The Sonnets have with few exceptions a historiographical character. We present a translation of the Sonette into Portuguese as well as commentaries about their content and their philosophical significance. We also comment rather briefly on Pettenkofer’s career as an empirical (...) chemist and later as a somewhat heterodox hygienist. (shrink)

An in-situ transmission electron microscopy straining technique has been used to investigate the dynamics of dislocation-defect interactions in ion-irradiated copper and the subsequent formation of defect-free channels. Defect removal frequently required interaction with multiple dislocations, although screw dislocations were more efficient at annihilating defects than edge dislocations were. The defect pinning strength was determined from the dislocation curvature prior to breakaway and exhibited values ranging from 15 to 175 MPa. Pre-existing dislocations percolated through the defect field but did not show (...) long-range motion, indicating that they are not responsible for creating the defect-free channels and have a limited contribution to the total plasticity. Defect-free channels were associated with the movement of many dislocations, which originated from grain boundaries or regions of high stress concentration such as at a crack tip. These experimental results are compared with atomistic simulations of the interaction of partial dislocations with defects in copper and a dispersed-barrier-hardening crystal plasticity model to correlate the observations to bulk mechanical properties.
