Die stratigraphischen Einheiten, durch welche heute die Erdgeschichte untergliedert wird, haben eine unterschiedliche und zum Teil recht komplexe Entstehungsgeschichte, wie hier am Beispiel des Keupers gezeigt werden soll. Das Wort ‘Keuper’ geht auf einen volkstümlichen Namen für bunte Tongesteine im Raum Coburg zurück. In den geologischen Sprachgebrauch wird es 1822 durch Leopold von Buch eingeführt, der es noch als Gesteinsnamen verwendet und die entsprechenden Schichten dem Buntsandstein zuweist. Die richtige Einstufung dieser Schichten über dem Muschelkalk gelang erstmals Ludwig Hausmann und (...) Peter Merian um 1820. Doch erst nachdem in den nachfolgenden Jahren deren Ergebnisse durch die Arbeit etlicher anderer Forscher bestätigt wurden, fand die neue, bis dahin unbenannte Formation aus bunten Mergeln und Sandsteinen breite Anerkennung. Als stratigraphischer Begriff, der auch Sandsteine und Gips umfaßt, wird die Bezeichnung Keuper erstmals von Friedrich Hoffmann im Jahre 1823 verwendet und von Christian Keferstein 1824 in die Literatur eingeführt. Eine wichtige Rolle spielten die Arbeit an den ersten geologischen Übersichtskarten Deutschlands und die Aufnahme der neuen Formation in die erste internationale Formationstabelle durch Keferstein . Mit der Integration des Keupers in die neue Formation ‘Trias’ durch Friedrich August von Alberti 1834 bekommt diese Einheit ihren seither festen Platz in der Stratigraphie.Geologic time is commonly subdivided by a set of stratigraphic terms, which all have their individual and sometimes complex histories. ‘Keuper’, now used as a stratigraphical term for the Upper Triassic, originated from a popular rock name of the Coburg area in southern Germany. The term ‘Keuper’, though still as a rock name, was first introduced into geological usage by Leopold von Buch in 1822, when he designated varicoloured marls and claystones, of what he thought to be Bunter Sandstein, as ‘Keuper’. In a stratigraphical sense, the term ‘Keuper-Formation’ was coined by Friedrich Hoffmann in 1823, who was the first to include sandstones and gypsum rocks with this notion. A year later it was introduced into the literature by Christian Keferstein. At this time, the existence of a distinct formation between Muschelkalk and Lias was already accepted by a number of geologists, though it had not yet been named. This ‘new’ formation has formerly been confused with Buntsandstein and even Carboniferous deposits by various authors until it was set into its right position by Ludwig Hausmann and Peter Merian in 1820. In the following years, the work of several geologists confirmed their results and led to general acceptance of the Keuper Formation as a separate entity. An important impetus came from the compilation of the first small-scale geological maps of Germany edited by Keferstein in the early 1820s, and from his international stratigraphical table , which already included the ‘Keuper-Formation’ as an integral part. In 1834, Friedrich August von Alberti included the ‘Keuper’ as part of the new Formation ‘Trias’ and thus defined its place in modern stratigraphy. (shrink)

Consider the claims that representations of physical laws are intersubjective, and that they ultimately provide the foundation for all other intersubjective knowledge. Those claims, as well as the deeper philosophical commitments that justify them, constitute rare points of agreement between the Marburg School neo-Kantians Paul Natorp and Ernst Cassirer and their positivist rival, Ernst Mach. This is surprising, since Natorp and Cassirer are both often at pains to distinguish their theories of natural scientific knowledge from positivist views like Mach’s, and (...) often from Mach’s views in particular. Thus the very fact of this agreement between the Marburg School neo-Kantians and their positivist stalking horse points to a deep current of ideas that runs beneath the whole of the post-Kantian intellectual context they shared.

The aim of this paper is to provide an account of how hunger motivates us to seek food and eat. It seems that the way that it feels to be hungry must play some role in it fulfilling this function. We propose that hunger is best viewed as a complex state involving both affective and somatic constituents, as well as, crucially, changes in the way in which the hungry agent’s attention is deployed. We argue that in order to capture the (...) distinctive way in which hunger motivates we need to articulate the relations amongst such components. The resulting account explains how hunger as an aversive affective reaction to a state of need motivates us specifically to eat and not to just to rid ourselves of the unpleasant sensations associated to it. We suggest, however, that there is more than this to the overall affective experience of the hungry agent, because hunger ordinarily facilitates the elicitation of other, positive affective reactions such as interest and appetite, and recruits them to further its function.

In the popular imagination, the relevance of Turing's theoretical ideas to people producing actual machines was significant and appreciated by everybody involved in computing from the moment he published his 1936 paper ‘On Computable Numbers’. Careful historians are aware that this popular conception is deeply misleading. We know from previous work by Campbell-Kelly, Aspray, Akera, Olley, Priestley, Daylight, Mounier-Kuhn, Haigh, and others that several computing pioneers, including Aiken, Eckert, Mauchly, and Zuse, did not depend on Turing's 1936 universal-machine concept. Furthermore, (...) it is not clear whether any substance in von Neumann's celebrated 1945 ‘First Draft Report on the EDVAC’ is influenced in any identifiable way by Turing's work. This raises the questions: When does Turing enter the field? Why did the Association for Computing Machinery honor Turing by associating his name to ACM's most prestigious award, the Turing Award?

La tesis principal que aquí se defiende es que, para Popper, la validez del conocimiento estuvo vinculada siempre a la dimensión pragmática del contexto de descubrimiento (e incluso dependía de ella). Constituye, pues, un error afirmar que, para él, 1) dicha validez estaba ligada a un "empirismo encubierto" (opuesto a la tesis sobre la carga teórica de toda observación), según lo ha planteado Ana Rosa Pérez Ransanz, y que 2) en sus ideas, los factores pragmáticos carecían de importancia epistemológica, como (...) lo ha afirmado Ambrosio Velasco. Para justificar esta tesis, se examinan tres argumentos expuestos en The Logic of Scientific Discovery, enfatizando el que se refiere al carácter disposicional de los términos con los que, para Popper, se formulan los enunciados descriptivos. The main thesis I assert here is that for Popper validity of knowledge was always linked to (and even supported by) the pragmatic dimension of the context of discovery. I hold it's wrong to claim that for this author 1) validity of knowledge was linked to a "hidden empiricism" (opposed to the theory-laden character of observation), such as Ana Rosa Pérez Ransanz had propounded, and 2) pragmatic issues were epistemologically irrelevant in his philosophy, such as Ambrosio Velasco has argued. To justify my thesis I examine three arguments exposed in The Logic of Scientific Discovery, emphasizing especially Popper's argument about the dispositional character of the concepts in which descriptive statements are formulated.

Storytelling is considered nowadays a proper strategy to encourage children to develop literary taste and reading and it is therefore being broadly practiced within educational spaces. Within this framework the present article deals with 140 reports on storytelling observation in schools for children’s education and first classes. These reports were carried out in different places in Porto Alegre and its surroundings. It was possible to observe that despite the joyful characteristic of the storytelling moment – that involves costumes, scenarios, puppets (...) – the way this activity has been conducted turned out to be very pedagogical in three dimensions. In the first place, the choice of many narratives and books reveals an explicit tendency to "civilize" the child or to form a certain kind of subject. In the second place, this pedagogical tendency becomes evident in the conversations carried out between storytellers and children after the storytelling. In this context certain "messages" of the narrative are frequently stressed. At last, in the interviews many storytellers explained their criteria to choose books and stories according to "the project that is being presently developed in the school" or according to "problems that are taking place in the classroom" and so on. In spite of this tendency, however, some reports allow to infer that many teachers are escaping the deliberate pedagogization the stories and are therefore siding with a discourse wherein pedagogical aspects are minimizedA contação de histórias é considerada, atualmente, uma estratégia adequada para iniciar as crianças no gosto pela leitura, sendo uma atividade generalizada nos espaços educativos. Dentro desse quadro, o artigo discute 140 relatos de observação de contação de histórias na Educação Infantil e anos iniciais, realizadas em espaços da região metropolitana de Porto Alegre . Assim, observou-se que, malgrado o caráter lúdico das horas do conto – com fantasias, cenários, fantoches –, há nelas uma evidente pedagogização, através de três dimensões: a primeira é a escolha de algumas histórias e/ ou livros que pretendem abertamente civilizar ou formar um determinado tipo de sujeito. Em segundo lugar, a pedagogização fica evidente nas conversas que a contadora de histórias realiza com crianças após a contação, uma vez que, frequentemente, se enfatizam as mensagens da história. Por fim, nas entrevistas realizadas com as contadoras, ao falarem dos critérios de escolha dos livros e das histórias, várias sinalizaram uma escolha de acordo com o "projeto que está sendo desenvolvido", com "problemas que estão ocorrendo na sala de aula", etc. Mesmo assim, algumas práticas observadas fugiram à pedagogização deliberada, mostrando que muitas professoras estão inseridas em outro discurso, em que a pedagogização é minimizada.

Introduction Nonconsequentialist ethicists have noted that small harms, goods, or claims should not count against large claims. For example, given a choice between saving one life and a large group of people with minor headaches, we ought to save the one life, no matter how large the group is. This principle has been called limited aggregation. The principle of limited aggregation might have implications on public health policy, given that public health policy involves weighing the claims of individuals against one (...) another. Aims and Methods I aim to show that limited aggregation has implications for policies on e-cigarettes and alternative nicotine delivery systems. The methodology used in this study involves critical analysis of existing literature and pre-theoretical moral views. Results This study does not use empirical research. Conclusions In deciding to allow or encourage the use of e-cigarettes or alternative nicotine delivery systems, we sometimes must weigh benefits to each existing smoker affected by the policy against risks to each nonsmoker affected. I argue in this paper that when these risks, to each individual nonsmoker, are sufficiently small, we ought not to count them against more significant benefits to smokers. This applies even when the number of nonsmokers affected by a policy exceeds the number of smokers. Implications This paper implies that policymakers ought to be sensitive to the scale of benefits or risks introduced by a policy on individuals. If the negative side effects, on each affected individual, of a proposed policy are sufficiently small, they do not count against the beneficial goals of that policy. Depending on the expected effects of each given e-cigarette policy, this may give policymakers defeasible reasons to prioritize the needs of current smokers, who may each gain a lot from various means of smoking cessation, over nonsmokers, who each may only have a small chance of picking up smoking.

Resumen:Por un lado, el trabajo pretende mostrar de qué modo el “tono” de Arendt en sus trabajos académicos, tal y como lo señalara Scholem en una de sus misivas críticas a la autora, lejos de ser frívolo o burlón (como se apuntaba en esa crítica) produce una brecha perturbadora, por la cual los lectores y las lectoras de Hannah Arendt pueden desvelar hipocresías y actuar con una nueva responsabilidad. Por otro lado, el artículo señala diversos conceptos filosóficos, algunos ya sometidos (...) a investigación por Arendt, que en sí mismos presentan la fuerza de crear un mundo y unos seres humanos, con la energía teórica y real necesaria como para transformarlos: “pensar”, “actuar”, “amar”, son algunos de ellos. En este último sendero, utilizaremos la ayuda de sus discípulas, Fina Birulés y Marina Garcés.Palabras clave: Hannah Arendt; Tono; Filosofía moral; Responsabilidad; Compasión; Historia. (shrink)

Much recent discussion of love concerns ‘the reasons for love’: whether we love for reasons and, if so, what sorts of things those reasons are. This chapter seeks to call into question some of the assumptions that have shaped this debate, in particular the assumption that love might be ‘responsive’ to reasons in something like the way that actions, beliefs, intentions and ordinary emotions are. I begin by drawing out some tensions in the existing literature on reasons for love, suggesting (...) that these arise in part because different interests expressed in the language of ‘reasons’ – the interests of explanation, justification and interpersonal understanding – pull us towards different kinds of account of reasons for love. This seems to count in favor of treating these interests separately, with different conceptions of the reasons that answer to them. This suggestion, as I explain, runs up against a certain conception of ‘responsiveness to reasons’, which I argue is implicitly assumed in many discussions of reasons for love. However, I argue that we should be skeptical about the application of this conception to love in light of the ontological differences between love and paradigm ‘reasons-responsive’ phenomena, potentially making room for the suggested methodological separation.

Anyone who has worked in Science for forty years can be much surprised to realize how little he now hears about evolution, compared with such former times. At present, evolution seems to be accepted as an axiomatic or universal principle, while the mechanism of it is not much considered, except by a small group of specialists, who work on the subject in greatly limited ways. This is practically a reversal of the former emphasis. The chemist would probably suggest that the (...) change is due to a better realization of the chemical difficulties involved in the mechanics of evolution, and his own change in viewpoint. The chemical difficulties will have increased to an almost incredible degree in this period, and his viewpoint will have changed correspondingly. A glance at some of these changes should illuminate the progress made in both subjects in this period. (shrink)

The last two words of the title for this essay are taken from a paper by R. S. Lillie, and the first phrase is also taken by implication from the same source. The study of chemical phenomena in life has progressed far enough so that underlying chemical causes, involved in Professor Lillie's picture of Biological Causation, may in part be discussed in general terms, and apart from the mass of detail known about the agents and processes involved. Moreover, this mass (...) of detail is now great enough so that even though we are far from having a complete or even a comprehensive picture of these causes at least some of the fundamental principles involved in the chemical aspects of biological causation are clearly revealed.

Ever since the beginning of the modern era of science, more than 300 years ago, the scipntist has been embarassed at times when he undertook to describe the scope and objectives of science. Part of this embarassment was due to the difficulty of setting up the scope and objectives in such a way as to leave room for future development, and at the same time to permit of seeing the limitations of science clearly and truthfully. Recently in an article “On (...) the possible philosophies of science”, Professor Malisoff made use of the old practise in philosophical discussion of using conjugate terms. These terms as used are so selected that complementary pairs characterize or describe an entity or whole of some kind. The difficulty in describing the scope, objectives and especially the limitations of science, arises chiefly from the difficulty of establishing some simple entity that will contain all of this as well, as the remainders that must be included, and that involve the limitations of science, chiefly. This use of conjugate terms offered a solution of this difficulty. (shrink)
