Agriculture should be viewed not as an industry but rather as a set of sectors organized around region, commodity, and institution. As such, agriculture adjusts well to a situation of “abundance” (excess supplies of major commodities).Although these sector interests are often referred to as “special interests,” they have effectively used public policy to generate agricultural development, and will continue to have a developmental impulse. Sector interests will, therefore, resist most proposals based on macrosystem perspectives which would reduce government support for (...) agricultural development. These sectors will continue to be quite influential in deciding agricultural policy, though they will find it possible to adjust not only to “abundance” in the market place, but also to such political constraints as may be imposed in pursuit of such goals as consumer health, soil conservation, and environmental preservation.

There is a traditional view of pain as a conscious phenomenon which satisfies the following two principles at least: Pain is essentially a belief- or cognition-independent sensation, given for consciousness in an immediate way, and pain′s unitary physical base is responsible for both its phenomenal or felt qualities and it′s functional, causal features. These are "The Raw Feels Principle" and "The Unity of Pain Principle" . Each is shown to be implausible. Evidence comes from recent pain research in a number (...) of dimensions. A further argument against The Unity of Pain Principle is constructed by analogy with facts about blindsight. The consequences of rejecting P or Q are examined in light of the traditional epistemological role of pain as exemplar of sensations thought to be foundational for knowledge, the prospects of a modularity theory of the pain system, recent accounts of pain among contemporary philosophers, a naturalist and realist conception of pain, and views about the status of Folk Psychology.

This paper investigates the status of the purported explanatory gap between pain phenomena and natural science, when the “gap” is thought to exist due to the special properties of experience designated by “qualia” or “the pain quale” in the case of pain experiences. The paper questions the existence of such a property in the case of pain by: (1) looking at the history of the conception of pain; (2) raising questions from empirical research and theory in the psychology of pain; (...) (3) considering evidence from the neurophysiological systems of pain; (4) investigating the possible biological role or roles of pain; and (5) considering methodological questions of the comparable status of the results of the sciences of pain in contrast to certain intuitions underpinning “the explanatory gap” in the case of pain. Skepticism concerning the crucial underlying intuitions seems justified by these considerations. (shrink)

Recent neuroscience and psychology of behavior have suggested that conscious decisions may have no causal role in the etiology of intentional action. Such results pose a threat to traditional philosophical analyses of action. On such views beliefs, desires and conscious willing are part of the causal structure of intentional action. But if the suggestions from neuroscience/psychology are correct, analyses of this kind are wrong. Conscious antecedents of action are epiphenomenal. This essay explores this consequence. It also notes that the traditional (...) alternative to causal analyses of intentional action is not threatened by the putative scientific findings. This, in turn, is ironic in that defenders of the noncausal accounts of action were thought to be in opposition to the natural sciences of action whereas the analyses in the causal style were "on the side of physicalism." This result is also assessed in what follows. (shrink)

Much of today's communication is carried out through various kinds of humor, and we therefore need to be able to understand its many aspects. Here, two of the world's leading pioneers in humor studies, Alleen and Don Nilsen, explore how humor can be explained across the numerous sub-disciplines of linguistics. Drawing on examples from language play and jokes in a range of real-life contexts, such as art, business, marketing, comedy, creative writing, science, journalism and politics, the authors use their own (...) theory of 'Features, functions and subjects of Humor' to analyze humor across all disciplines. Each highly accessible chapter uses a rich array of examples to stimulate discussion and interaction even in large classes. Supplemental PowerPoints to accompany each of the 25 chapters are available online, taking many of the insights from the chapters for further interactional discussions with students. (shrink)

This book explores central issues of modern Russian religious thought by focusing on the work of Soloviev and three religious philosophers who further developed his ideas in the early twentieth century: P. A. Florensky, Sergei Bulgakov, and ...

This paper investigates the status of the purported explanatory gap between pain phenomena and natural science, when the “gap” is thought to exist due to the special properties of experience designated by “ qualia ” or “the pain quale” in the case of pain experiences. The paper questions the existence of such a property in the case of pain by: looking at the history of the conception of pain; raising questions from empirical research and theory in the psychology of pain; (...) considering evidence from the neurophysiological systems of pain; investigating the possible biological role or roles of pain; and considering methodological questions of the comparable status of the results of the sciences of pain in contrast to certain intuitions underpinning “the explanatory gap” in the case of pain. Skepticism concerning the crucial underlying intuitions seems justified by these considerations. (shrink)

SIMPLE SEEING I met Virgil Aldrich for the first time in the fall of 1969 when I arrived in Chapel Hill to attend a philosophy conference. My book, Seeing and Knowing,1 had just appeared a few months earlier.

In Stephanie Beardman's discussion of the empirical results of Kahneman and Tversky and Kahneman, et al. on pain preference and rational utility decision she argues that an interpretation of these results does not require that false memory for pain episodes yields irrational preferences for future pain events. I concur with her conclusion and suggest that there are reasons from within the pain sciences for agreeing with Beardman's reinterpretation of the Kahneman, et al. data. I cite some of these theoretical and (...) empirical reasons. I engage in some speculation as to why preferences for pain experiences, which harbor the Peak and Ending profile, make biological sense. Given the results from the pain sciences and the clinical practices based in them, I conclude that the medical ethical issue Kahneman raises and Beardman tries to solve is not a pressing moral demand on medical practitioners.

What follows raises objections to some arguments that claimthat a principle of applicability of ordinary pain talkconstrains developments in the pain sciences. A more apt pictureof lay use of pain language shows its non-theoretic character.Since instrumentalism and eliminativism are philosophical viewsabout the status of theories of pain, neither is a threatto clinical use of standard pain lingo. Perfected pain theoryis likely to enhance and improve pain language in clinicalsettings, should such theory find its way into popular ideasand talk of pain.

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)

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)

The focus of this study was to analyze the content, distribution, and comparative genome relationships of 996 chromosome bin-mapped expressed sequence tags accounting for 2266 restriction fragments on the homoeologous group 3 chromosomes of hexaploid wheat. Of these loci, 634, 884, and 748 were mapped on chromosomes 3A, 3B, and 3D, respectively. The individual chromosome bin maps revealed bins with a high density of mapped ESTs in the distal region and bins of low density in the proximal region of the (...) chromosome arms, with the exception of 3DS and 3DL. These distributions were more localized on the higher-resolution group 3 consensus map with intermediate regions of high-mapped-EST density on both chromosome arms. Gene ontology classification of mapped ESTs was not significantly different for homoeologous group 3 chromosomes compared to the other groups. A combined analysis of the individual bin maps using 537 of the mapped ESTs revealed rearrangements between the group 3 chromosomes. Approximately 232 of the consensus mapped ESTs matched sequences on rice chromosome 1 and revealed large- and small-scale differences in gene order. Of the group 3 mapped EST unigenes ∼21 and 32% matched the Arabidopsis coding regions and proteins, respectively, but no chromosome-level gene order conservation was detected. (shrink)

To localize wheat ESTs on chromosomes, 882 homoeologous group 6-specific ESTs were identified by physically mapping 7965 singletons from 37 cDNA libraries on 146 chromosome, arm, and sub-arm aneuploid and deletion stocks. The 882 ESTs were physically mapped to 25 regions flanked by 23 deletion breakpoints. Of the 5154 restriction fragments detected by 882 ESTs, 2043 were localized to group 6 chromosomes and 806 were mapped on other chromosome groups. The number of loci mapped was greatest on chromosome 6B and (...) least on 6D. The 264 ESTs that detected orthologous loci on all three homoeologs using one restriction enzyme were used to construct a consensus physical map. The physical distribution of ESTs was uneven on chromosomes with a tendency toward higher densities in the distal halves of chromosome arms. About 43% of the wheat group 6 ESTs identified rice homologs upon comparisons of genome sequences. Fifty-eight percent of these ESTs were present on rice chromosome 2 and the remaining were on other rice chromosomes. Even within the group 6 bins, rice chromosomal blocks identified by 1-6 wheat ESTs were homologous to up to 11 rice chromosomes. These rice-block contigs were used to resolve the order of wheat ESTs within each bin. (shrink)
