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)

Mrs. F, seventy‐five, was diagnosed with Alzheimer's. She and her spouse often discussed how to handle the progression of the disease. She was adamant about not coming to the point where she would be unable to recognize herself, her husband, or their son and daughter. The manner she chose was voluntarily stopping eating and drinking (VSED), and she chose a specific date on which to carry out her plan. She asked her husband to promise, should she ever waver and request (...) nutrition or hydration, to remind her of the reasons she had chosen for pursuing this path.Mrs. F's ability to function was beginning to wax and wane. Sometimes she was her old self, and sometimes she had no recollection of her past identity. After she voluntarily stopped eating and drinking, the couple's promise created a dilemma for her professional caregivers. She asked for food and drink. Her husband and family reminded her of the reasons she had chosen VSED: “Remember, you didn't want to live in a nursing home, and you didn't want us to be responsible for caring for you at home. You believe that stopping eating and drinking will allow you to die with dignity.” Although they also asked Mrs. F, “What do you want to do?” the family asked the professional caregivers to respect her original choice to stop eating and drinking. Mrs. F still evidenced decision‐making capacity but often did not recall having chosen VSED. She again requested food and drink, from family and the professional caregivers.Can VSED be carried out for a patient whose advanced dementia makes disciplined voluntary action difficult? (shrink)

Background: The American Medical Association, the British Medical Association and the Canadian Medical Association have guidelines that specifically discourage physicians from self-prescribing or prescribing to family members, but only the BMA addresses informal prescription requests between colleagues. Objective: To examine the practices of paediatric providers regarding self-prescribing, curbsiding colleagues, and prescribing and refusing to prescribe to friends and family. Methods: 1086 paediatricians listed from the American Academy of Paediatrics 2007 web-based directory were surveyed. Results: 44% of eligible survey respondents returned (...) usable surveys. Almost half of respondents had prescribed for themselves. An equal number had informally requested a prescription from a colleague. Three-quarters stated they had been asked to prescribe a prescription drug for a first-degree or second-degree relative, and 51% had been asked by their spouse. Eighty-six per cent stated that they had refused to write a prescription on at least one occasion for a friend or family member. The following reasons “strongly influenced” their decision to refuse a prescription request: outside of provider’s expertise ; patient’s need for his or her own physician ; not medically indicated ; need for a physical examination. Conclusion: These data confirm that most physicians have engaged in self-prescribing or curbside requests for prescriptions. It can be argued that curbsiding is more morally problematic than self-prescribing because it implicates a third party, and should be discouraged regardless of whether the requester is a colleague, family member or friend.

The objectives of this study were to develop a high-density chromosome bin map of homoeologous group 7 in hexaploid wheat, to identify gene distribution in these chromosomes, and to perform comparative studies of wheat with rice and barley. We mapped 2148 loci from 919 EST clones onto group 7 chromosomes of wheat. In the majority of cases the numbers of loci were significantly lower in the centromeric regions and tended to increase in the distal regions. The level of duplicated loci (...) in this group was 24% with most of these loci being localized toward the distal regions. One hundred nineteen EST probes that hybridized to three fragments and mapped to the three group 7 chromosomes were designated landmark probes and were used to construct a consensus homoeologous group 7 map. An additional 49 probes that mapped to 7AS, 7DS, and the ancestral translocated segment involving 7BS also were designated landmarks. Landmark probe orders and comparative maps of wheat, rice, and barley were produced on the basis of corresponding rice BAC/PAC and genetic markers that mapped on chromosomes 6 and 8 of rice. Identification of landmark ESTs and development of consensus maps may provide a framework of conserved coding regions predating the evolution of wheat genomes. (shrink)

The thought of G. W. F. Hegel has had a deep and lasting influence on a wide range of philosophical, political, religious, aesthetic, cultural and scientific movements. But, despite the far-reaching importance of Hegel's thought, there is often a great deal of confusion about what he actually said or believed. This is an invaluable introduction for philosophical beginners and a useful reference source for more advanced scholars and researchers.

John F. Kavanaugh and W. Norris Clarke, two twentieth-century Jesuits, contributed to philosophy through their development of a Thomistic and personalist view of reality emphasizing the human endowments of knowing, freely choosing, and loving. While spiritual exercises played a role in the formation of both Jesuits, the function of spiritual exercises in their own philosophy has not been explored. Recent interest in philosophy as a way of life provides a means by which this can be accomplished. In their work Michel (...) Foucault and Pierre Hadot have shown how spiritual exercises function in the formation of the self and in the acquisition of a synoptic vision that allows contemplation of one’s participation in the whole. This paper shows that while Kavanaugh primarily uses spiritual exercises in his philosophy to accomplish a disciplinary/formational aim Clarke’s aim is dialogical/exploratory. A brief examination of the Spiritual Exercises of Ignatius of Loyola reveals how these different aims in fact complement one another. (shrink)

ArgumentKeeping records has always been an essential part of science. Aside from natural history and the laboratory sciences, no other observational science reflects this activity of record-keeping better than astronomy. Central to this activity, historically speaking, are tools so mundane and common that they are easily overlooked; namely, the notebook and the pencil. One obvious function of these tools is clearly a mnemonic one. However, there are other relevant functions of paperwork that often go unnoticed. Among these, I argue, is (...) the strategic use made of different procedures of record keeping to prolong observational time with a target object. Highlighting this function will help us to appreciate the supporting role played by the notebook and the pencil to extend the observational time spent with a target object. With objects as delicate, faint, and mysterious as the nebulae, the procedures used to record their observations helped nineteenth-century observers overcome the temporal handicaps and limitations of large and clumsy telescopes, mounted in the altazimuth manner. To demonstrate the importance of paper and pencil, I will closely examine the observing books, the drawings found therein, and the telescopes of three nineteenth-century observers of the nebulae: Sir John F. W. Herschel, Lord Rosse, and William Lassell. (shrink)

Today we are all familiar with the iconic pictures of the nebulae produced by the Hubble Space Telescope’s digital cameras. But there was a time, before the successful application of photography to the heavens, in which scientists had to rely on handmade drawings of these mysterious phenomena. Observing by Hand sheds entirely new light on the ways in which the production and reception of handdrawn images of the nebulae in the nineteenth century contributed to astronomical observation. Omar W. Nasim investigates (...) hundreds of unpublished observing books and paper records from six nineteenth-century observers of the nebulae: Sir John Herschel; William Parsons, the third Earl of Rosse; William Lassell; Ebenezer Porter Mason; Ernst Wilhelm Leberecht Tempel; and George Phillips Bond. Nasim focuses on the ways in which these observers created and employed their drawings in data-driven procedures, from their choices of artistic materials and techniques to their practices and scientific observation. He examines the ways in which the act of drawing complemented the acts of seeing and knowing, as well as the ways that making pictures was connected to the production of scientific knowledge. An impeccably researched, carefully crafted, and beautifully illustrated piece of historical work, Observing by Hand will delight historians of science, art, and the book, as well as astronomers and philosophers.

How can self-deception avoid intention and conscious recognition? Nine processes of self-deception seem to involve biased links between plausible ideas. These processes allow self-deceivers to regard individual conclusions as fair and reasonable. Bias is only detected by comparing broad patterns, which individual self-deceivers will not do.

Schelling's first systematic attempt to articulate a complete philosophy of nature.

The use of biotechnology in food productiongives rise to consumer concerns. The term ``consumerconcern'' is often used as a container notion. Itincludes concerns about food safety, environmental andanimal welfare consequences of food productionsystems, and intrinsic moral objections againstgenetic modification. In order to create clarity adistinction between three different kinds of consumerconcern is proposed. Consumer concerns can be seen assigns of loss of trust. Maintaining consumer trustasks for governmental action. Towards consumerconcerns, governments seem to have limitedpossibilities for public policy. Under current (...) WTOregulations designed to prevent trade disputes,governments can only limit their policies to 1) safetyregulation based upon sound scientific evidence and 2)the stimulation of a system of product labeling. Ananalysis of trust, however, can show that ifgovernments limit their efforts in this way, they willnot do enough to avoid the types of consumer concernsthat diminish trust. The establishment of a technicalbody for food safety – although perhaps necessary –is in itself not enough, because concerns that relatedirectly to food safety cannot be solved by ``pure''science alone. And labeling can only be a good way totake consumer concerns seriously if these concerns arerelated to consumer autonomy. For consumer concernsthat are linked to ideas about a good society,labeling can only provide a solution if it is seen asan addition to political action rather than as itssubstitution. Labeling can help consumers take uptheir political responsibility. As citizens, consumershave certain reasonable concerns that can justifiableinfluence the market. In a free-market society, theyare, as buyers, co-creators of the market, andsocietal steering is partly done by the market.Therefore, they need the information to co-create thatmarket. The basis of labeling in these cases, however,is not the good life of the individual but thepolitical responsibility people have in their role asparticipants in a free-market. Then, public concernsare taken seriously. Labeling in that case does nottake away the possibilities of reaching politicalgoals, but it adds a possibility. (shrink)

This is an English translation of Schelling's Ideas for a Philosophy of Nature (first published in 1797 and revised in 1803), one of the most significant works in the German tradition of philosophy of nature and early nineteenth-century philosophy of science. It stands in opposition to the Newtonian picture of matter as constituted by inert, impenetrable particles, and argues instead for matter as an equilibrium of active forces that engage in dynamic polar opposition to one another. In the revisions of (...) 1803 Schelling incorporated this dialectical view into a neo-Platonic conception of an original unity divided upon itself. The text is of more than simply historical interest: its daring and original vision of nature, philosophy, and empirical science will prove absorbing reading for all philosophers concerned with post-Kantian German idealism, for scholars of German Romanticism, and for historians of science.
