The text of the tract De arcubus similibus was published for the first time by M. Curtze in 1887. However, after examining some more Latin manuscripts and the Arabic MS Oxford, Bodleian Library, Marsh 663 it appeared, that Curtze's edition was rather an adaptation. Also Curtze's suggestion that Jordanus Nemorarius was the author was very probably wrong. The author of the tract was the Egyptian mathematician Ahmed ibn Jusuf as appears from the Latin manuscripts, and its translator, very probably, Gerard (...) of Cremona. In the tract Ahmed tried to prove, that the assertion ‘similar arcs are also equal arcs’ was wrong . His starting points were the propositions Euclid III, 20 and 21. Consequently, the tract can be looked upon as a commentary on the third book of the Elements. (shrink)

ZusammenfassunuIn dem vorliegenden Bericht über einige Arbeiten des Verfassers und eine daran anschliessende Arbeit von G. Emde, Marburg, wird eine Reihe von Ergebnissen behandelt, die die Kombinationen der Grundmodalitäten « Möglichkeit » und « Notwendigkeit » betreffen. Ausgehend von sehr allgemeinen Rahmenkodifikaten wird die durch Basisreduktion zu gewinnende Liste der endlich vielen implikativen Modalitätenlogiken mit idempotenter Möglichkeit erörtert; bei wichtigen Unterklassen der nicht notwendig idempotenten implikativen Modalitätenlogiken treten neben der Basisreduktion vor allem spezielle Entscheidungsprobleme in den Vordergrund.RésuméDans le rapport ci‐dessus (...) concernant quelques travaux de l'auteur et le travail de M. G. Emde qui s'y rapporte, il s'agit d'un ensemble de résultats sur la combinaison des modalités fondamentales de « possibilité» et de « nécessité». Partant de quelques codifications cadres très générales, I'auteur discute la liste en nombre fini des logiques modales implicatives à« possibilité» idempotente, une liste qui est obtenue par une réduction des bases. Quant à certaines sous‐classes importantes des logiques implicatives qui ne sont pas nécessairement idempotentes, outre la réduction des bases, les problèmes de décision qui leur sont spéciaux, se trouvent placés au premier plan.In the present report on some papers of the author and on a sequel to them by G. Emde, Marburg, a series of results concerning the combination of the basic modalities « possibility » and « necessity » are treated. Starting from some very general framing‐codifications, the list of the finitely many implicative modal logics with idempotent « possibility » which is obtainable through basis reduction is discussed. Besides basis reduction, in the case of some important subclasses of the not‐necessarily‐idempotent implicative modal logics, attention is given to the special decision problems. (shrink)

Intent and mitigating circumstances play a central role in moral and legal assessments in large-scale industrialized societies. Al- though these features of moral assessment are widely assumed to be universal, to date, they have only been studied in a narrow range of societies. We show that there is substantial cross-cultural variation among eight traditional small-scale societies (ranging from hunter-gatherer to pastoralist to horticulturalist) and two Western societies (one urban, one rural) in the extent to which intent and mitigating circumstances influence (...) moral judgments. Although participants in all societies took such factors into account to some degree, they did so to very different extents, varying in both the types of considerations taken into account and the types of violations to which such considerations were applied. The particular patterns of assessment characteristic of large-scale industrialized societies may thus reflect relatively recently culturally evolved norms rather than inherent features of human moral judgment.

Patient centred diagnosis is best practised through shared decision making; an iterative dialogue between doctor and patient, whichrespects a patient’s needs, values, preferences, and circumstances. -/- Shared decision making for diagnostic situations differs fundamentally from that for treatment decisions. This has important implications when considering its practical application. -/- The nature of dialogue should be tailored to the specific diagnostic decision; scenarios with higher stakes or uncertainty usually require more detailed conversations.

L. M. de Rijk supposed in 1982 that two anonymous logical tracts in the Viennese Codex 4698, fol. 18r–27v, may be the work of Martinus Anglicus to whom a tract on consequences and one on obligations are ascribed in that codex. The tract on supposition of which the Viennese codex hands down only a fragment of the beginning is contained completely in Hs I 613 of the Stadtbibliothek Mainz, fol. 20vb–21vb. This finding ensures the authorship of Martinus Anglicus and allows (...) to ascribe an Introduction into Logic in some seven parts to him. Martin’s tract on supposition and the more detailed one by Thomas Manlevelt show some resemblances in structure and content, the first being presumably the later one. This paper presents an edition of Martin’s Tractatus de suppositione from the Mainz manuscript and an introduction regarding the author and his work. (shrink)

Editors’ Note: As a matter of policy, the editors believe that publishing several reviews of selected texts is a valuable exercise which will enable a cross-section of views to be aired.Copies of this report can be obtained from the Nuffield Council on Bioethics, 28 Bedford Square, London WC1B 3EG, U.K. . The report publishes the recommendation of a Working Party set up in January 1995. Following a wide public consultation, the Working Party prepared its report on xenotransplantation which has been (...) endorsed by the Nuffield Council on Bioethics. (shrink)

Purpose: Commenting on the transcript of a lecture. Findings: The document reconstructs the development of the original 1973 lecture by Heinz von Foerster into his best-known paper, On Constructing a Reality. Many aspects of that paper can be identified as being shaped through interaction with the audience. Implications: The lecture documented here was a forerunner of a central paper in constructivism.
