Aktuelle bioethische Debatten werden vor allem von zwei Schwierigkeiten überschattet: zum einen von der Unklarheit des Begriffes menschlicher Autonomie. Hier geht es um individualethische Fragen, vor allem um Beginn und Ende menschlichen Lebens. Zum anderen bedroht die Verschiebung individueller Wissensträgerschaft zum anonymen Kollektivsubjekt angesichts einer zunehmenden Ökonomisierung des Gesundheitswesens das ärztliche Ethos des Helfens und Heilens. Diese und weitere konfliktgeladene Problemstellungen diskutiert Jan P. Beckmann in seinem neuen Buch.

Germany since 1990 has one of the strictest human embryo protection laws, yet according to the Stem Cell Act of 2002 allows, under strict conditions, the import and use of human embryonic stem cells (hESC) for high priority research goals. The author tries to show how this is taken to be coherent by the parliamentary majority (though not necessarily by the general public) in Germany. In doing so, he firstly looks into the chronicle of the debate in Germany showing its (...) different stages since 1999, then dwells upon the relation between the law and the role of ethics in this issue, and thirdly presents the two fundamentally different positions of the German debate, that is, that the human embryo created for IVF purposes is a human being and stands from its very beginnings under the constitutional principles of respect for, and protection of, human life versus the position that before being implanted the human embryo may become a human being and therefore belongs to the human species only potentially, so that its right to life protection may be assessable over against other high priority goals, such as research aiming at possible help for patients with life-endangering diseases. In spite of the Stem Cell Act of 2002, the debate of the German general public goes on, especially due to the recent EU 6th Research Framework Program which plans to also fund hESC research.

The author inquires into the relation between the production of genetic knowledge on the one hand, and human autonomy and self-determination on the other. He does so by specifying the notions of “genetic test” and “human autonomy”; by discussing the epistemic status of genetic knowledge, given its importance for the clarification of its anthropological and ethical implications; and by inquiring into some ethical implications by investigating the conditions under which genetic knowledge of the individual may justifiably be established. This discussion (...) shows that the autonomy-based right to self-determination as far as gene in formation is concerned, is fundamental. This has major implications, which the author identifies with regard to the difficult problem of the moral legitimacy of the use of genetic knowledge in the context of insurance policies. S. Afr. J.

Researchers rely on psychometric principles when trying to gain understanding of unobservable psychological phenomena disconfounded from the methods used. Psychometric models provide us with tools to support this endeavour, but they are agnostic to the meaning researchers intend to attribute to the data. We define method effects as resulting from actions which weaken the psychometric structure of measurement, and argue that solution to this confounding will ultimately rest on testing whether data collected fit a psychometric model based on a substantive (...) theory, rather than a search for a model that best fits the data. We highlight the importance of taking the notions of fundamental measurement seriously by reviewing distinctions between the Rasch measurement model and more generalised 2PL and 3PL IRT models. We then present two lines of research that highlight considerations of making method effects explicit in experimental designs. First, we contrast the use of experimental manipulations to study measurement reactivity during the assessment of metacognitive processes with factor-analytic research of the same. The former suggests differential performance-facilitating and -inhibiting reactivity as a function of other individual differences, whereas factor-analytic research suggests a ubiquitous monotonically predictive confidence factor. Second, we evaluate differential effects of context and source on within-individual variability indices of personality derived from multiple observations, highlighting again the importance of a structured and theoretically grounded observational framework. We conclude by arguing that substantive variables can act as method effects and should be considered at the time of design rather than after the fact, and without compromising measurement ideals.

Uniwersytet jako biurokratycznie i rynkowo zarządzane przedsiębiorstwo był obiektem krytyki od lat 80. minionego wieku — w Stanach Zjednoczonych Allan Bloom nazwał go wtedy multiwersytetem, a trochę później Bill Readings pisał już o „uniwersytecie w ruinie” (in ruins), który ukrywa się za szyldem „doskonałości”. Polski uniwersytet przejął ekonomiczne kryteria ewaluacji nauki — wymierne w liczbach grantów i punktów. Merkantylizacja wiedzy stwarza szereg problemów także natury etycznej — prowadzi do zaniżenia lub porzucenia wszelkich standardów akademickich, do degradacji autorytetu w nauce, krytyki (...) naukowej, faktycznej jakości badań i nauczania. Czy na współczesnym uniwersytecie jest w ogóle miejsce na zachowania podlegające ocenie moralnej? Jakie są umiejętności wymagane do — i warunki możliwości — stosowania norm moralnych w życiu akademickim? (shrink)

This paper deals with the exact constructions of the regular heptagon in Greek and Arabic geometry, which are preserved in a number of mainly unpublished Arabic manuscripts. Appended are editions of the Arabic texts and English translations of Propositions 17 and 18 of the “Book of the Construction of the Circle, Divided into Seven Equal Parts”, attributed to Archimedes, and of the “Book on the Construction of the Heptagon in the Circle and the Division of the Rectilineal Angle into Three (...) Equal Parts” by the 10th century geometer Al-Sijzi. (shrink)

This collection of essays reflects the wide range of David Pingree's expertise in the scientific texts of Ancient Mesopotamia, Greece, India, Persia, and the medieval Arabic, Hebrew and Latin traditions. Both theoretical aspects and the practical applications of the exact sciences-in time keeping, prediction of the future, and the operation of magic-are dealt with. The book includes several critical editions and translations of hitherto unknown or understudied texts, and a particular emphasis is on the diffusion of scientific learning from one (...) culture to another, and through time. Above all, the essays show the variety and sophistication of the exact sciences in non-Western societies in pre-modern times. (shrink)

Much has been done on the publication of original sources in Arabic during the past 30 years, but much more remains to be done. Some of the recent multiple editions are unnecessary duplication of work and therefore waste of energy. This energy could be better spent on the publication of unpublished sources, and on studies involving the contextualization of Islamic sciences. Furthermore, historians of pre-modern science should work on the popularization of their wonderful subject. This exoteric work is as important (...) as esoteric research, because the survival of the field depends on its image among various audiences outside the community of historians of science. (shrink)

The question of bodylines of the memory in the eschatological perspective During last decades the cognitive sciences have progressed a lot in analysing the link between mind and body on the field of philosophy of mind. The results of the body-mind investigations influence largely also theology. The classical theological thought considers the will, the reason and the memory as faculties of the soul. However, contemporary neuroscience attempts, with some success, to discover physical substrates of these faculties, which impacts also philosophy (...) of the mind. In this perspective, mutability and fragility of human body that is, according to psychologists, the memory’s ground, as well as human identity taken in its theological understanding, determined by the memory but transcending the temporal life, require some re-analysis of the spiritual dimension of the memory and some connection between the spiritual and the bodily sphere in the perspective of relation of the man with God. Though, theology must respect the scientific solutions of the body-mind question. In order to undertake it, the very object of theology and neuroscience has to be analysed to ascertain whether the memory examined by both sciences constitutes the same phenomenon. Then, one should analyse the philosophical assumptions of their discourses. Only these preliminary inquiries will allow to determine the philosophical area to build an integral reflexion. In turn, only this area may constitute the basis for such an anthropological-theological system that could retain its integrity vis-à-vis the discoveries of neuroscience. (shrink)

The tradeoff hypothesis in the speech–gesture relationship claims that (a) when gesturing gets harder, speakers will rely relatively more on speech, and (b) when speaking gets harder, speakers will rely relatively more on gestures. We tested the second part of this hypothesis in an experimental collaborative referring paradigm where pairs of participants (directors and matchers) identified targets to each other from an array visible to both of them. We manipulated two factors known to affect the difficulty of speaking to assess (...) their effects on the gesture rate per 100 words. The first factor, codability, is the ease with which targets can be described. The second factor, repetition, is whether the targets are old or new (having been already described once or twice). We also manipulated a third factor, mutual visibility, because it is known to affect the rate and type of gesture produced. None of the manipulations systematically affected the gesture rate. Our data are thus mostly inconsistent with the tradeoff hypothesis. However, the gesture rate was sensitive to concurrent features of referring expressions, suggesting that gesture parallels aspects of speech. We argue that the redundancy between speech and gesture is communicatively motivated. (shrink)

Mathematical texts raise particular dilemmas for the translator. With its arm’s-length relation to verbal expression and long-standing “mathematics is written for mathematicians” ethos, mathematics lends itself awkwardly to textually centered analysis. Otherwise sound standards of historical scholarship can backfire when rigidly upheld in a mathematical context. Mathematically inclined historians have had more faith in a purported empathic sixth sense—and there is a case to be made that this is how mathematical authors have generally expected their works to be read—but it (...) is difficult to pin down exact evidentiary standards for this supposed instinct. This essay urges that both of these points of view, for all the tension between them, be kept in the historian’s toolbox. It illustrates these considerations with a case study from the Ptolemaic astronomical tradition on computing lunar model parameters from eclipse data. (shrink)
