Objectives: To analyse and compare the surveys on German doctors and judges on end of life decision making regarding their attitudes on the advance directive and on the dying process.Design: The respondents were to indicate their agreement or disagreement to eight statements on the advance directive and to specify their personal view on the beginning of the dying process.Participants: 727 doctors in three federal states and 469 judges dealing with guardianship matters all over Germany.Main measurements: Comparisons of means, analyses of (...) variance, pivot tables and factor analyses .Results: Three attitude groups on advance directive were disclosed by the analysis: the decision model, which emphasises the binding character of a situational advance directive; the deliberation model, which puts more emphasis on the communicative aspect; and the delegation model, which regards the advance directive as a legal instrument. The answers regarding the beginning of the dying process were broadly distributed, but no marked difference was observed between the responding professions. The dying process was assumed by most participants to begin with a life expectancy of only a few days.Conclusions: A high degree of valuation for advance directive was seen in both German doctors and judges; most agreed to the binding character of the situational directive. Regarding the different individual concepts of the dying process, a cross-professional discourse on the contents of this term seems to be overdue. (shrink)

Im Rahmen des Modellvorhabens „Patienten als Partner—Tumorpatienten und ihr Mitwirken bei medizinischen Entscheidungen“ wurden zwischen März 2002 und August 2003 272 palliativ behandelte Tumorpatienten nach ihrer Einstellung zur Patientenverfügung und zur gewünschten Beteiligung an medizinischen Entscheidungen befragt. Von den Befragten kannten 30% Patientenverfügungen nicht, darunter signifikant mehr Befragte mit formal niedrigerem Bildungsabschluss. Es hatten bereits 11% eine Patientenverfügung abgeschlossen, 22% wollten wahrscheinlich eine abschließen, und 30% wollten keine abschließen. Es fand sich ein statistisch signifikanter Zusammenhang zwischen dem Abschluss einer Patientenverfügung (...) und dem Wunsch nach mehr eigener Entscheidungsverantwortung. Die Einstellung zur Patientenverfügung und der Wunsch nach partizipativer Entscheidungsfindung stehen in keinem statistisch signifikanten Zusammenhang. Patienten mit schriftlichen Vorausverfügungen haben einen erhöhten Kommunikations- und Rückkopplungsbedarf, auf den Ärzte sensibel eingehen sollten. Bei der Information über Patientenverfügungen sollten Menschen mit niedrigerem Bildungsstand mehr als bisher berücksichtigt werden. (shrink)

In the field of socio-legal studies or law and society scholarship, it is rare to find empirically rich and conceptually sophisticated understandings of actual legal practice. This book, in contrast, connects the conceptual and the empirical, the abstract and the concrete, and in doing so shows the law to be an irreducibly social, material and temporal practice. Drawing on cutting-edge work in the social study of knowledge, it grapples with conceptual and methodological questions central to the field: how and where (...) judgment empirically takes place; how and where facts are made; and how researchers might study these local and concrete ways of judging and knowing. Drawing on an ethnographic study of how narratives and documents, particularly case files, operate within legal practices, this book's unique and innovative approach consists of rearticulating the traditional boundaries separating judgment from knowledge, urging us to rethink the way truths are made within law.

Konzeptionen des Neuen und der Erneuerung begleiten die menschlichen Kulturen und Zeiten. Der Beitrag nimmt konkrete Lebens- und Textwelten der biblischen Überlieferung des Judentums und des Christentums in den Blick, wie sie in den Traditionen der Hebräischen Bibel/des Alten Testaments zu finden sind. Zum einen zeigt sich dabei eine pragmatische und auf die Förderung der Lebensverhältnisse von Gemeinschaft und Mensch orientierte Rede vom Neuen. Zum anderen gibt es ein Wissen um Neues und Vollkommenes als Wissen um einen Schöpfer, der Vollkommenes (...) und Schönes schafft (Kohelet) sowie als Gegenbild zu Defizientem und Bösem, mit dem Bildung, Gesellschaft und Religion ringen.

Die alttestamentliche Gottesrede kennt in ihren unterschiedlichen Spielarten ein wechselseitiges Verweisverhältnis zwischen Gott und Mensch. Darin begegnet die Perfektion Gottes als Grenzbestimmung und das Imperfekte als Modus der Darstellung Gottes. In der Konsequenz lassen sich weder der Mensch noch Gott in den Vorstellungen des Perfekten oder des Imperfekten allein angemessen erfassen.

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.

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)

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)

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)

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)

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)

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)

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)

In this article, I examine the relation between Bateson and Guattari’s ecological thoughts: two thinkers whose ecological ideas at first sight have a lot in common. In order to show the difference between the thoughts of both thinkers, I will take my clue from Guattari’s remark that he parts ways with Bateson on the role of context. Explaining the role of context in both authors will allow me to show how Guattari’s thought implies both an endorsement and a critique of (...) cybernetics, and, specifically, promoting a machinic rather than cybernetic ecology. I will conclude by indicating what is at stake in this distinction. (shrink)

In this paper I address the current debate on ontic versus epistemic conceptualizations of mechanistic explanation in the mechanisms literature. Illari recently argued that good explanations are subject to both ontic and epistemic constraints: they must describe mechanisms in the world in such fashion that they provide understanding of their workings. Elaborating upon Illari’s ‘integration’ account, I argue that causal role function discovery of mechanisms and their components is an epistemic prerequisite for achieving these two aims. This analysis extends Illari’s (...) account in important ways, putting more pressure on ontic readings of mechanistic explanation and providing an answer to the question how ontic and epistemic constraints on mechanistic explanation are related. I argue these point in terms of cases on memory research drawn from neuroscience and research on extinct neurogenetic mechanisms from early nervous systems biology. (shrink)

Over the past few years, the Virtual Organization (VO) paradigm has been emerging as an ideal solution to support collaboration among globally distributed entities (individuals and/or organizations). However, due to rapid technological and societal changes, there has also been an astonishing growth in technologies and services for mobile users. This has opened up new collaborative scenarios where the same participant can access the VO from different locations and mobility becomes a key issue for users and services. The nomadicity and mobility (...) introduces additional challenges for managing collaboration in VO environments. This paper focuses on the Identity Management challenge in a Mobile Dynamic VO environment, which is a VO that takes into account nomadicity and seamless mobility aspects as elaborated within the EU funded project Akogrimo (Access to Knowledge through the Grid in a mobile world). The resulting work is the design of the Akogrimo Identity Management system supporting the authentication and authorization process across the different administrative domains of the Mobile Dynamic VO. This design follows the service oriented approach and integrates the different perspectives: that of the network, that of the user and that of the service provider. Such an integration requires facing challenges; both from the architectural and technological viewpoints because different ‘worlds’ (i.e. network and service level) leverage different (and sometimes conflicting) approaches when addressing Identity Management.

Some alethic pluralists maintain that there are two kinds of truths operant in our alethic discourse: a realist kind and an anti-realist kind. In this paper, we argue that such a binary conception cannot accommodate certain social truths, specifically truths about race. Most alethic pluralists surprisingly overlook the status of racial truths. Douglas Edwards is, however, an exception. In his version of alethic pluralism—Determination Pluralism—racial truths are superassertible (anti-realist) true rather than correspondence (realist) true. We argue that racial truths exhibit (...) features of both superassertibility (anti-realism) and correspondence (realism). This suggests a fuzzy boundary between realist and anti-realist kinds of truth. There may be a continuum rather than a dichotomy of truths. We conclude by sketching one way for alethic pluralists to accommodate such a notion. (shrink)

This paper investigates conceptions of explanation, teleology, and analogy in the works of Immanuel Kant (1724-1804) and Georges Cuvier (1769-1832). Richards (2000, 2002) and Zammito (2006, 2012, 2018) have argued that Kant’s philosophy provided an obstacle for the project of establishing biology as a proper science around 1800. By contrast, Russell (1916), Outram (1986), and Huneman (2006, 2008) have argued, similar to suggestions from Lenoir (1989), that Kant’s philosophy influenced the influential naturalist Georges Cuvier. In this article, I wish to (...) expand on and further the work of Russell, Outram, and Huneman by adopting a novel perspective on Cuvier and considering (a) the similar conceptions of proper science and explanation of Kant and Cuvier, and (b) the similar conceptions of the role of teleology and analogy in the works of Kant and Cuvier. The similarities between Kant and Cuvier show, contrary to the interpretation of Richards and Zammito, that some of Kant’s philosophical ideas, whether they derived from him or not, were fruitfully applied by some life scientists who wished to transform life sciences into proper sciences around 1800. However, I also show that Cuvier, in contrast to Kant, had a workable strategy for transforming the life sciences into proper sciences, and that he departed from Kant’s philosophy of science in crucial respects.
