This collection of essays in honor of Prof. Stig Andur Pedersen's 60th Birthday spans over a broad scope of topics, ranging from mathematical modelling over realism in philosophy of science to an analysis of apology after medical mistakes. The unusually broad range is a fair but still inadequate reflection of the work of Stig Andur Pedersen, a philosopher and scientist whose range of interests, abilities and production is itself unusually broad.

A total of 944 expressed sequence tags generated 2212 EST loci mapped to homoeologous group 1 chromosomes in hexaploid wheat. EST deletion maps and the consensus map of group 1 chromosomes were constructed to show EST distribution. EST loci were unevenly distributed among chromosomes 1A, 1B, and ID with 660, 826, and 726, respectively. The number of EST loci was greater on the long arms than on the short arms for all three chromosomes. The distribution of ESTs along chromosome arms (...) was nonrandom with EST clusters occurring in the distal regions of short arms and middle regions of long arms. Duplications of group 1 ESTs in other homoeologous groups occurred at a rate of 35.5%. Seventy-five percent of wheat chromosome 1 ESTs had significant matches with rice sequences, where large regions of conservation occurred between wheat consensus chromosome 1 and rice chromosome 5 and between the proximal portion of the long arm of wheat consensus chromosome 1 and rice chromosome 10. Only 9.5% of group 1 ESTs showed significant matches to Arabidopsis genome sequences. The results presented are useful for gene mapping and evolutionary and comparative genomics of grasses. (shrink)

It is demonstrated on the basis of the Dirac equation that quarks cannot be confined by a vector gluon potential of the form(r/r 0)a or[ln(r/r 0]a, a>0, if the quark-gluon interaction conserves parity. In order to confine quarks with the parity-conserving interaction, the effective gluon potential must be a pseudovector or a scalar. These are shown in a simple Yang-Mills field with theSU(2) group.

A clear presentation and exploration of the philosophical implications of the classical picture of the physical world and the ways in which contemporary physics has changed it. Capek argues that physics has now moved from a universe governed by a "timeless world formula" toward a world which is irreversible and incomplete, where "becoming has been re-instated." The author's careful attention to the differences between the special and general theories of relativity helps to clear up important misconceptions about the space-time continuum (...) and the "dilatation" of time. Capek is more successful in explaining and clarifying physics than he is in assessing its precise philosophic impact.--B. J. H. (shrink)

Sherburne has the two-fold purpose of framing an aesthetic theory which gains its coherence and clarity by its derivation from a speculative system, and of exploring the adequacy of that system by applying it to one dimension of experience. He begins by developing clearly the categorial notions of Whitehead's mature philosophy and exhibiting them as integral parts of the speculative scheme, and in some cases revising and reformulating them significantly. Using this material, he then frames an aesthetic theory treating such (...) questions as the ontological status of a work of art, aesthetic experience, and artistic creation. A well-written study that illuminates some of the more difficult aspects of Whitehead's thought, and contributes to the discussion of the metaphysical issues of aesthetics.--B. J. H. (shrink)

Many of the selections included are readily available, but the editor has earned our gratitude for reprinting the series of seven papers read before the Aristotelian Society from 1915-1923, and for making readily accessible the 1927 essay, "Time." The somewhat lengthy introduction adds little to the value of the book, and is occasionally inaccurate. --B. J. H.

Twenty-four scientists and philosophers contribute to this volume, which constitutes the proceedings of the 1959 meetings of the American Association for the Advancement of Science. Six symposia deal with theory construction; empirical and conventional elements in physical theory; induction, probability and simplicity; the logic of variables and constants; philosophical issues of quantum theory; and the methodology of psychology and the social sciences. Many of the contributions are excellent; most deal with controversial issues, and generate considerable life in the discussions and (...) commentaries.--B. J. H. (shrink)

This historico-critical analysis of the concept of mass is the third in Jammer's series of studies of fundamental physical concepts. His fascinating account traces its intricate historical evolution from early notions of matter and the medieval concept of mass as quantitas materiae to the dynamic conceptions of mass. The concept is followed through the three stages of conceptualization ; systematization ; and formalization. Jammer further treats mass in relation to the electromagnetic theories; special and general relativity; quantum mechanics and the (...) theory of elementary particles; and the modern "space-theories" of matter. He concludes that no final clarification of the concept has yet been attained, despite the efforts of both physicists and philosophers. This difficult material is handled with great scholarship and control, skillfully interpreted, and concisely presented --B. J. H. (shrink)

In this introduction to social problems, sixteen social scientists discuss the major forms of deviant behavior and social disorganization. The introduction attempts to elicit the general theoretical orientation which is implicit in the specialized studies making up the main body of the book.--B. J. H.

In this inaugural address, a professor of applied mathematics develops the theme that new concepts such as "entropy" introduced in the mathematical description of nature have an influence far beyond the mathematical sciences, extending to such diverse fields as biology, the social sciences, religion, philosophy, literary analysis, etc.--B.

H.B.G. Casimir's life, interests and works are intertwined with the important developments that have taken place in physics during this century. This book was compiled by his friends and admirers in honour of his 80th birthday and concentrates mainly on Casimir's achievements in the field of physics, though without ignoring the peripheral areas of the history and philosophy of physics in which he was greatly interested. The book is divided into four parts. Part I describes Casimir's teachers, Ehrenfest, Bohr and (...) Pauli, and will be of general interest due to the key role which these physicists played in modern developments. The articles do give new facts and provide new insights into the history of modern physics. Part II consists of essays on recent developments in various areas of physics in which Casimir has taken an active interest, such as the modern concept of time, statistical foundations of electrodynamic theory and field theory. The subjects covered in Part III have been selected because of Casimir's efforts in the industrial research area of physics. They cover past, present and future expectations in research. (shrink)

We develop a framework for assessing security market quality, relating five elements of market design to three metrics of market integrity and two metrics of market efficiency. We empirically implement this integrity–efficiency MQ framework by testing a hypothesis that trade-based ramping manipulation at the close raises execution costs on 24 security markets worldwide. Estimating a simultaneous equations model of ramping incidence, spreads, and the probability of deploying real-time surveillance, we show that quoted bid-ask spreads are positively related to the incidence (...) of MTC across seven liquidity deciles. The magnitude is economically significant; improving market integrity by cutting MTC in half reduces spreads 6–11 %. Allowing direct market access in conjunction with RTS, conducting auctions at the close, and developing regulations that require surveillance, all reduce MTC and thereby lower spreads, assuring better market integrity and enhancing market efficiency. Introducing circuit breakers or prohibiting shorts poses integrity–efficiency tradeoffs. (shrink)

The rapid development of physics, the result of observations made and ideas introduced within the last few decades, has brought about a change in the whole system of physical concepts. This fact is common knowledge, and has already attracted the attention of philosophers. It is less well known that geometry too has had its crises, and undergone a reconstruction. For centuries, so-called “geometrical intuition” was used as a method of proof. In geometrical demonstrations, certain steps were allowed because they were (...) “self-evident,” because the correctness of the conclusion was “shown by the adjoined diagram,” etc. A crisis occurred in geometry because such intuition proved to be untrustworthy. Many of the propositions regarded as self-evident or based upon the consideration of diagrams turned out to be false. And so Euclidean geometry was reconstructed by methods free from all intuitive elements and strictly logical in nature. Moreover, for more than a century, various other geometries have been devised purely as logical constructions. Since they start with assumptions different from those of Euclid, and lead to conclusions partly in contradiction with his theorems, they are called “non-Euclidean.” Nevertheless, each one of these geometries is a closed system of propositions exempt from contradiction. Recently, some of them have even found application in physics. (shrink)
