What is science? How is scientific knowledge affected by the society that produces it? Does scientific knowledge directly correspond to reality? Can we draw a line between science and pseudo-science? Will it ever be possible for computers to undertake scientific investigation independently? Is there such a thing as feminist science? In this book the author addresses questions such as these using a technique of 'cognitive play', which creates and explores new links between the ideas and results of contemporary history, philosophy, (...) and sociology of science. New ideas and approaches are applied to a wide range of case studies, many of them from controversial and contested science. This book will be of interest to historians and sociologists of science, to anyone interested in science studies, and to educated general readers with an interest in the history, philosophy, and social context of science.

The paper reviews criteria which have been used to distinguish science from nonscience and from pseudo–science, and it examines the extent to which they can usefully be applied to “creation science.” These criteria do not force a clear decision, especially as creation science resembles important eighteenth–century forms of orthodox science. Nevertheless, the proponents of creation science may be accused of pious fraud in failing to concede in their political battles that their “science” is tentative and tendentious and will continue to (...) be so while it remains archaic and poorly integrated into the rest of science.

The new disciplines of experimental psychology and physical chemistry which emerged in late-nineteenth-century Germany were transmitted rapidly to North America, where they flourished. At the time, American higher education was growing fast and undergoing important organizational changes. It was then especially receptive to such European ideas as these new growth points in German science. However, although there were important similarities in the transmission of the two sciences, experimental psychology was changed far more than physical chemistry by the transfer. Physical chemistry (...) was able to fit into a flourishing pattern of German-inspired chemistry in higher education. Psychology was more dependent on its intellectual and social context, and the American context was quite different from that of Germany. (shrink)

The following three papers (by R.G.A. Dolby, R.N.D. Martin, and A. Thomson) were presented to the Science & Religion Forum at its annual meeting in Liverpool, Britain, in March 1988, under the general theme of Tradition & Authority in Science and Religion. An abbreviated version of the fourth paper given at that meeting re-entitled STS Perspective: Value Systems, by W.F. Williams, is printed on pp. 219-221 of this volume (Vol. 9, No. 4). A copy of the full version is (...) available from either the author or the editorial office. (shrink)

In this paper we consider the classes of all continuous $\mathcal {L}$ -(pre-)structures for a continuous first-order signature $\mathcal {L}$. We characterize the moduli of continuity for which the classes of finite, countable, or all continuous $\mathcal {L}$ -(pre-)structures have the amalgamation property. We also characterize when Urysohn continuous $\mathcal {L}$ -(pre)-structures exist, establish that certain classes of finite continuous $\mathcal {L}$ -structures are countable Fraïssé classes, prove the coherent EPPA for these classes of finite continuous $\mathcal {L}$ -structures, and (...) show that actions by automorphisms on finite $\mathcal {L}$ -structures also form a Fraïssé class. As consequences, we have that the automorphism group of the Urysohn continuous $\mathcal {L}$ -structure is a universal Polish group and that Hall’s universal locally finite group is contained in the automorphism group of the Urysohn continuous $\mathcal {L}$ -structure as a dense subgroup.

Cognitive Task Analysis (CTA) helps researchers understand how cognitive skills and strategies make it possible for people to act effectively and get things done. CTA can yield information people needemployers faced with personnel issues, market researchers who want to understand the thought processes of consumers, trainers and others who design instructional systems, health care professionals who want to apply lessons learned from errors and accidents, systems analysts developing user specifications, and many other professionals. CTA can show what makes the workplace (...) workand what keeps it from working as well as it might.Working Minds is a true handbook, offering a set of tools for doing CTA: methods for collecting data about cognitive processes and events, analyzing them, and communicating them effectively. It covers both the "why" and the "how" of CTA methods, providing examples, guidance, and stories from the authors' own experiences as CTA practitioners. Because effective use of CTA depends on some conceptual grounding in cognitive theory and researchon knowing what a cognitive perspective can offerthe book also offers an overview of current research on cognition.The book provides detailed guidance for planning and carrying out CTA, with chapters on capturing knowledge and capturing the way people reason. It discusses studying cognition in real-world settings and the challenges of rapidly changing technology. And it describes key issues in applying CTA findings in a variety of fields. Working Minds makes the methodology of CTA accessible and the skills involved attainable. (shrink)

_Purpose._ This article reveals the importance of the analysis of the theory of generations to identify the essential characteristics of the phenomenon of youth. _Theoretical basis_ of this study is socio-philosophical anthropology, i.e. philosophical anthropology using certain methods of sociological, socio-psychological and ethnological research, as well as philosophical comprehension of the application of these methods in special sciences. _Originality._ The authors rethought the theoretical and practical potential of generational theory through its reconceptualization based on philosophical anthropology, which created an opportunity (...) to shift research attention from the attempts to identify superhistorical characteristics of youth to the identification of the essential nature of specific historical and sociocultural features of young people as representatives of a particular culture. _Conclusions._ Defining the youth phenomenon requires accounting at least three constraints that on the one hand, play a role of warnings that deter from theoretical and practical errors in the study of the youth phenomenon, and on the other hand, guidelines for identifying real, specific characteristics of youth as a social phenomenon. Limitations of theoretical and practical analysis of young people are as follows: first, the need to consider demographic data not as final, but only as initial and preliminary, such that require further substantive socio-cultural analysis; second, the inadmissibility of ignoring the cultural diversity of the manifestations of the youth phenomenon, instead the need to identify the special characteristics of youth of different ethnic, religious and other groups; third, the need to take into account the specifics of self-identification of those who identify themselves as young people as a social group.

We investigate the relationship of the degrees of splittings of a computably enumerable set and the degree of the set. We prove that there is a high computably enumerable set whose only proper splittings are low 2.

Nineteenth-century Russia reverberated with ideas of women's liberation as a condition of genuine equality in society. These ideas came to form the basis of an entire tradition linking the "woman's" question and the "social" question together and defining the democratic character of the women's movement in Russia.

Ventricular Fibrillation is responsible for a majority of sudden cardiac death, but little is known about how ventricular tachycardia (VT) degenerates into ventricular fibrillation. Several clinical studies focused only on preventing VT with a class III antiarrhythmic drug resulted in many deaths. Our simulations investigate the interactions between an antiarrhythmic drug likely to suppress a VT and a Figure 8 reentry. A parameter AAR is introduced to increase the action potential duration and therefore simulate various Class III drugs. Simulations are (...) ran under several conditions (phases of the reentry, values of AAR, durations). They show that a VT can be suppressed whatever the phase of the reentry but it strongly depends on the duration of the effect. It confirms that a drug which can suppress a reentry can also worsen it. It also shows a great variety of activation patterns and thus the complexity of antiarrhythmic drugs effects. Simulations also demonstrate that suppressing VT is an increasing function of AAR.
