An elementary presentation is given of classical and relativistic collision dynamics based upon the principle of conservation of momentum. The concepts of mass are shown to be implicitly defined and their basic properties are rigorously derived and discussed. Luxons and tachyons are treated on the same footing as material particles.

We develop a process-based framework, articulating the escalation of difference between “private” self and “public” display as an alternative trajectory in the pursuit of authenticity to alignment and compromise. A parsimonious model presents an endogenous dynamic of binary choice that generates momentum toward polarization. The model is illustrated in the context of “black” metal – a branch of heavy metal music that appeared in Norway in the early 1990s, notorious for its involvement in criminal activities. Using fanzine data, we construct (...) a narrative of how a process of escalation led to innovation and transgression through self-selection and exclusion. The analysis addresses two related theoretical problems – what motivates actors to challenge normative scripts and “burn the bridges” to social acceptance, and why such challenges may prove more effective in achieving recognition than compromise. Examples from politics, culture and sports reinforce the importance of these problems. (shrink)

Dans sa lecture de l'Hommage de Lacan à Marguerite Duras pour Le Ravissement de Lol V. Stein, Erik Porge met en évidence, cinquante ans après, l'actualité de ce texte où Lacan lie la problématique de la sublimation à celle d'une fiction clinique faisant cas. Il montre en effet que la transmission de la clinique de l'analyste participe de la dynamique de la sublimation de celui-ci. La topologie du fantasme, avec laquelle cette folie féminine - qui s'inscrit dans la suite (...) de Marguerite Anzieu (cas Aimée) et des soeurs Papin - est abordée, ouvre le lecteur à une dynamique transférentielle et de sublimation par son articulation à la pulsion. En même temps que Lacan parle de la sublimation, il est ravi par le texte et fait acte de sublimation dans l'écriture de son Hommage, en nouant l'objet de sa propre pulsion au Ravissement de Lol V. Stein et à Marguerite Duras elle-même. Dans un mouvement de retour sur sa lecture de ce texte, Lacan élève la lettre à la dignité de la Chose (définition de la sublimation) ; le style devient condition d'accès au cas et fait lui-même cas.

Six palimpsest folios – or, to be accurate, three bifolios – of the Verona manuscript, Biblioteca Capitolare XL, contain fragments of a Latin translation of Euclid's Elements: fols. 331v–r and 326v–r, 341r–v and 338r–v, 336r–v and 343r–v. The folios are dated to around a.d. 500, and the text is written in capital script in two columns. Unfortunately the folios have suffered severe damage from various chemical substances, which were used by nineteenth-century scholars in attempts to retrieve the underlying text. Nevertheless, (...) an edition of the fragments finally appeared in 1964 by M. Geymonat. (shrink)

We model the optimal copulation duration in the yellow dungflyScathophaga stercoraria, assuming that males optimize their reproductive success per day. The independent state-variables of a male are the actual sperm reserves, the female encounterrate and the time of the day. We used stochastic dynamic programming to predict the optimal copulation duration. The model predicts that copulation duration should increase (i) for larger males, (ii) for males with a better previous diet (iii) for males accepting more females (iv) for males staying (...) away from the dung during a whole day. It also predicts that (v) males on a restricted diet should accept fewer matings, (vi) testes size should shrivel during the day, (vii) the correlation coefficient between copulation duration and sequence number should decrease with increasing initial sperm reserve and with increasing number of copulations performed on a given day.There are two essential differences between our model and a model of Parker (1992). (i) Our model assumes that males optimize per day. Parker's model assumes that males optimize per mating bout, one bout comprising many days. (ii) Since all the important state variables depend only on the moment of the copulation, our model does not assume a long-time memory in dungflies, and it is more flexible than Parker's model. Overall, both models explain the data available equally well. (shrink)

"For at kunne leve og virke og for at kunne planlægge vort eget liv på længere sigt, må vi tage stilling til livets tre hovedproblemer: Hvad kan vi vide? Hvad tør vi håbe? Og hvad skal vi gøre? Det er netop disse problemer, de store filosoffer har tænkt igennem langt mere dybtgående og grundigt, end man sædvanligvis har mulighed for at gøre det." I en vis forstand er vi alle sammen filosoffer, for vi har alle et bestemt livssyn, om vi (...) er klar over det eller ej. Professor i filosofi Svend Erik Stybes bog beskriver ikke blot forskellige livssyn, som er opstået gennem filosofihistorien i løbet af de sidste mange århundreder. Han giver også en definition af begrebet livssyn, som de fleste vil kunne relatere til og få til at give mening i forhold til deres eget liv. Bogen "De store tænkere og vort livssyn" fra 1963 henvender sig til enhver, der har interesse for livets store og små spørgsmål og forskellige filosoffer og idéhistorikeres tilgang dertil. Svend Erik Stybe (1919-1995) var en dansk idéhistoriker og forfatter, der udgav et væld af bøger om både dansk og europæisk filosofi- og idéhistorie gennem de sidste mange hundrede år. Han skrev blandt andet bøger til brug i undervisning i idéhistorie på gymnasiet og universitetet, opslagsværker om filosofi og idéhistorie samt bøger om specifikke filosoffer som Jean-Jacques Rousseau, John Locke og Baruch de Spinoza. Svend Erik Stybe blev udnævnt til professor i filosofi ved Københavns Universitet i 1970, hvor han forblev frem til sin pension i 1989. (shrink)

As an extension of the well-known Action Description Language A introduced by M. Gelfond and V. Lifschitz [8] C. Baral and M. Gelfond recently defined the diafect AC which supports the description of concurrent actions [1]. Also, a sound but incomplete encoding of AC by means of an extended logic program was presented there. In this paper, we work on interpretations of contradictory inferences from partial action descriptions. Employing an interpretation different from the one implicitly used in AC, we present (...) a new dialect which allows to infer sound information from contradictory descriptions and to describe non-determinism and uncertainty. Furthermore, we give the first sound and complete encoding of AC, using equational logic programming, and extend it to as well. (shrink)

It is gratifying to see that philosophers' continued interest in Words and Objections has been so strong as to motivate a paperback edition. This is gratifying because it vindicates the editors' belief in the permanent im portance of Quine's philosophy and in the value of the papers com menting on it which were collected in our volume. Apart from a couple of small corrections, only one change has been made. The list of Professor Quine's writings has been brought up to (...) date. The editors cannot claim any credit for this improvement, however. We have not tried to imitate the Library of Living Philosophers volumes and to include Professor Quine's autobiography in this volume, but we are fortunate to publish here his brand-new auto bibliography. 1975 THE EDITORS TABLE OF CONTENTS V PREFACE 1 EDITORIAL INTRODUCTION 1. 1.

Bioethicists frequently call for empirical researchers to engage participants and community members in their research, but don't themselves typically engage community members in their normative research. In this article, we describe an effort to include members of the public in normative discussions about the risks, potential benefits, and ethical responsibilities of social and behavioral genomics (SBG) research. We reflect on what might—and might not— be gained from engaging the public in normative scholarship and on lessons learned about public perspectives on (...) the risks and potential benefits of SBG research and the responsible conduct and communication of such research. We also provide procedural lessons for others in bioethics who are interested in engaging members of the public in their research. (shrink)

How should scarce healthcare resources be distributed? This is a contentious issue that became especially pressing during the pandemic. It is often emphasised that studies exploring public views about this question provide valuable input to the issue of healthcare priority setting. While there has been a vast number of such studies it is rarely articulated, more specifically, what the results from these studies would mean for the justification of principles for priority setting. On the one hand, it seems unreasonable that (...) public values would straightforwardly decide the ethical question of how resources should be distributed. On the other hand, in a democratic society, it seems equally unreasonable that they would be considered irrelevant for this question. In this paper we draw on the notion of reflective equilibrium and discuss the relevance and roles that empirical studies may plausibly have for justification in priority setting ethics. We develop a framework for analysing how different kinds of empirical results may have different kinds of implications for justification. (shrink)

In a recent article in this journal, I claimed that the widely held counterfactual comparative account of harm violates two very plausible principles about harm and prudential reasons. Justin Klocksiem argues, in a reply, that CCA is in fact compatible with these principles. In this rejoinder, I shall try to show that Klocksiem’s defense of CCA fails.
