A total of 1918 loci, detected by the hybridization of 938 expressed sequence tag unigenes from 26 Triticeae cDNA libraries, were mapped to wheat homoeologous group 4 chromosomes using a set of deletion, ditelosomic, and nulli-tetrasomic lines. The 1918 EST loci were not distributed uniformly among the three group 4 chromosomes; 41, 28, and 31% mapped to chromosomes 4A, 4B, and 4D, respectively. This pattern is in contrast to the cumulative results of EST mapping in all homoeologous groups, as reported (...) elsewhere, that found the highest proportion of loci mapped to the B genome. Sixty-five percent of these 1918 loci mapped to the long arms of homoeologous group 4 chromosomes, while 35% mapped to the short arms. The distal regions of chromosome arms showed higher numbers of loci than the proximal regions, with the exception of 4DL. This study confirmed the complex structure of chromosome 4A that contains two reciprocal translocations and two inversions, previously identified. An additional inversion in the centromeric region of 4A was revealed. A consensus map for homoeologous group 4 was developed from 119 ESTs unique to group 4. Forty-nine percent of these ESTs were found to be homoologous to sequences on rice chromosome 3, 12% had matches with sequences on other rice chromosomes, and 39% had no matches with rice sequences at all. Limited homology was found between wheat ESTs on homoeologous group 4 and the Arabidopsis genome. Forty-two percent of the homoeologous group 4 ESTs could be classified into functional categories on the basis of blastX searches against all protein databases. (shrink)

It has been argued that if an animal is psychologically like us, there may be more scientific reason to experiment upon it, but less moral justification to do so. Some scientists deny the existence of this dilemma, claiming that although there are scientifically valuable similarities between humans and animals that make experimentation worthwhile, humans are at the same time unique and fundamentally different. This latter response is, ironically, typical of pre-Darwinian beliefs in the relationship between human and non-human animals. Another (...) irony is that debate about such issues has facilitated the participation once more of philosophers in questions concerning experimental psychology: ironic because laboratory-oriented psychologists, especially since the turn of the last century, had been eager to establish the independence of their subject from any influence of philosophy and its investigative methods, as well as from any kind of anthropomorphism.In Britain, certainly more so than in the United States, ethical constraints have prevented the development of psychological research with animals along certain routes. By the 1980s British professional and academic societies had published codes of conduct and guidelines for their members, in part responding to public concern about the welfare of animals in the psychological laboratory. What led to the establishment of these codes and guidelines? This paper analyses the historical background against which professional concern for ethical cost in experimental animal psychology began to take shape, leading to the societies' open pronouncements of the 1980s.

In lieu of an abstract, here is a brief excerpt of the content:86 HISTORY OF PHILOSOPHY lamblichi Chalcidensis ex Coele-Syria de vita Pythagorica liber, lamblichos, Pythagoras. Legende--Lehre---Lebensgestaltung. Griechisch und Deutsch, herausgegeben, iibersetzt und eingeleitet von Michael yon Albrecht. (Ziirich & Stuttgart: Artemis, 1963. Pp. 280. = Die Bibliothek der Alten Welt, Reihe Antike und Christentum.) The present edition and translation again makes available one of the texts most valuable for the understanding of the world of late antiquity. The earlier editions, (...) especially that of L. Deubner (1937), are out of print. The fact that this document has been translated into German for the first time is also very helpful, since Iamblichos is sometimes difficult to understand. A brief but nevertheless informative introduction rightly emphasizes that Iamblichos intended to present an introduction and initiation into the Pythagorean way of life rather than a biography of Pythagoras based upon historically trustworthy materials. Although the biography of Pythagoras is certainly a part of the book, it serves only as the ideal example of the Pythagorean way of life, as Iaznblichos sees it. However, more than merely a work of Iamblichos, it ought to be recognized as a "fundamental document of the image of man in later antiquity" (p. 11). The text is based upon L. Deubner's edition, but occasionally it takes up older conjectures or returns to the tradition (for a more detailed discussion cf. W. Burkert, Gnomon 37, 1965, 24ff.). The index and the explanatory notes are also helpful, although the latter prove to be too brief and do not adequately call the reader's attention to the problems of sources, tradition, and composition. One can only agree with von Albrecht that we still need a modem commentary (p. I1). H. D. BETZ Claremont, CaliIornia Agrippa and the Crisis o] Renaissance Thought. By Charles G. Nauert, Jr. (Urbana: University of Illinois Press, 1965. Pp. vi W 374. $8.00.) One of the most influential and widely read thinkers of the early sixteenth century was the German Heinrich Cornelius Agrippa von Nettisheim (1486-1535). His many works were reprinted often, as well as being translated into several vernacular languages. The De incertitudine et vanitate omnium scientiarum et atrium of 1526, for example, went through at least 16 printings before 1700 and appeared in Italian (1547), English (1569), French (1582), and Dutch (1651) translations, which were themselves often reprinted. Although interest in Agrippa has waned somewhat since the seventeenth century, there is still a significant amount of scholarly debate regarding his importance and the meaning of his writings. Professor Nauert's monograph is the fruit of many years' study of Agrippa's life, thought, and milieu. In it he clearly places Agrippa in his historical context, accurately sketching his background and influence. After a brief introduction (pp. 1-7), the study is essentially divided into two parts: The first (pp. 8-115) traces Agrippa's life and intellectual development, the second (pp. 116-334) discusses in some detail a number of the key themes developed in his writings. There is also a substantial bibliography (pp. 335-,355) and a quite complete and accurate index (pp. 357-374). Although the mass of material which Nanert brings to our attention indicates the opposite, one sometimes gets the impression that the author tends to underestimate the importance of his subject. For example, he says, "Agrippa von Nettisheim is now a forgotten figure in the intellectual history of the West" (p. 322), but this does not seem to be the case. Although much work remains to be done, at least five books have been devoted to Agrippa in the past half century and, indeed, at least seven articles have appeared in the past ten years on one or another aspect of his life and thought. The very fact that Nanert can argue with so much vigor against the views of contemporary scholars like Lynn Thomdike and Paola Zambelli indicates that it is anything but a dead issue. As it is, Nauert's book clearly and accurately describes Agrippa's place in the intellectual ambiance of the sixteenth century. It gives the first detailed analysis of Agrippa's life and thought in English in recent BOOK REVIEWS 87 times and is the first full*scale attempt to exhaustively treat... (shrink)

The Einstein equations can be written as Fierz-Pauli equations with self-interaction, $W\gamma _{ik} = - G_{ik} + \tfrac{1}{2}g_{ik} g^{mn} G_{mn} - k(T_{ik} - \tfrac{1}{2}g_{ik} g^{mn} T_{mn} )$ together with the covariant Hilbert-gauge condition, $(\gamma _i^h - \tfrac{1}{2}\delta _i^k g^{mn} \gamma _{mn} )_{;k} = 0$ where W denotes the covariant wave operator and G ik the Einstein tensor of the metric g ik collecting all nonlinear terms of Einstein's equations. As is known, there do not, however, exist plane-wave solutions γ ik(z)with (...) g ik Z,i Z,k=0of these equations such that what is essential to the introduction of gravitons is not satisfied in general relativity. This nonexistence corresponds with the uncertainty relation,Δp(Δg*)2(Δx)3≥h hG/ c 3 concerning the total nonlinear gravitational field g *ik =g k +γ k. (shrink)

For two hundred years, Americans have believed that they have an obligation to improve the lot of humanity, a belief that has consistently shaped U.S. foreign policy. Yet within this consensus, there are two competing schools of thought: the "exemplarist" school (Brands' term) which holds that what America chiefly owes the world is the benign example of a well-functioning democracy, and the "vindicationist" school which argues that force must sometimes supplement a good example. In this book, H.W. Brands traces the (...) evolution of these two schools as they emerged in the thinking and writing of the most important public thinkers of the past two centuries. (shrink)
