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)

By the death, last summer, of Jack Robson, the world of utilitarian studies and a wider world of scholarship on both sides of the Atlantic lost one of their most distinguished figures. It would not be appropriate here, even if it were possible now, to attempt a full and measured assessment of his work. Writing only a few months after the news of his death, while the sense of loss is still so sharp for all his many friends, two things (...) are possible. Something can and should be said to acknowledge and celebrate Robson's achievement as a scholar; and to this can be added some personal recollections of one whose human qualities were as outstanding as his scholarship.

Ruhollah Khomeini views on clergy and professional ethics.

It is notorious that great philosophers are apt to be misunderstood. Controversy rages about their work, and sometimes they are credited with completely contradictory views. Consider the sharply contrasted opinions of Plato's political thought by Sir Karl Popper, on the one hand, and G. C. Field and H. B. Acton on the other.

This paper attempts some integration of two perspectives on questions about rationality and irrationality: the classical conception of irrationality as sophism and themes from the romantic revolt against Enlightenment reason. However, since talk of "reason" and "the irrational" often invites rigid dualities of reason and its opposites (such as feeling, intuition, faith, or tradition), the paper turns to "intelligence" in place of "reason," thinking of human intelligence as something less abstract, less purely theoretical, and more firmly rooted in practice, including (...) communicative practice. "Intelligence" is "reason" naturalized. -/- . (shrink)

This paper proceeds from an analysis (Callaway 1992, pp. 239-240) of a role of conflict in the origin of value commitments, a pervasive sociological pattern in the development of unifying group values which transforms personal conflicts, or differences, into large-scale collective conflicts. I have urged that these forces are capable of distorting even the cognitive processes of science and that they are a chief reason why value claims are regarded as incapable of objective evaluation. The thesis of the present paper (...) is that romantic collectivism (uncritical attachment to an identification group) renders members passive with respect to the ideals or content embodied in collective identity and that this is often exploited to convert groups into instruments of personal power. The issue is examined by reference to Reinhold Niebuhr's 1932 thesis of the inevitability of group egoism and inter-group conflicts and an opposing pragmatist conception of moral development, self-identity, and the individual's relationship to reference communities.

This new edition emphasizes Emerson's philosophy and thoughts on such issues as freedom and fate; creativity and established culture; faith, experience, and evidence; the individual, God, and the world; unity and dualism; moral law, grace, and compensation; and wealth and success. Emerson's text has been fully annotated to explain difficult words and to clarify his references. The Introduction, Notes, Bibliography, Index, and Chronology of Emerson's life help the reader understand his distinctive outlook, his contributions to philosophy, and his place in (...) American culture and society. (shrink)

Professor H. James Birx shows how the never-ending controversy of human evolution came to be. He details the events that caused thinkers like Charles Darwin to develop his theory of evolution, and what ideas caused some people to reconcile a somewhat mystical theology with a concrete model of the universe. He tells you how Darwin's work infuriated everybody from "God-fearing" Christians to the church heirarchies. Birx explains how scientific advances and philosophical arguments have made beliefs about divine intervention as the (...) origin of man a moot point. He shows how creationism ignores proven scientific facts, and how human evolution remains a much sounder truth. You'll read how some western religions are starting to accept evolution as the process which creates life on earth. You'll also learn why scientific evolution and creationism have not been accepted together and how bold attempts to merge the two ideas have failed miserably. (shrink)
