The permissibility of circulatory determination of death (CDD) preceding organ procurement remains controversial. This paper discusses the controversy and the liceity of irreversible circulatory cessation as a determinant of death. When specific protocols have been satisfied, including a waiting period of five minutes of asystole, CDD licitly signals the disintegration of the unitary and integrated whole that was the living human person. The author contends that after terminating disproportionate care, a surrogate may rely on irreversible circulatory cessation thus determined and (...) may authorize organ donation, including limited pre-death procedures that are consonant with the dignity and well-being of the dying patient-donor.

A comprehensive empirical study of value, explicitly indebted to the work of R. B. Perry, but brought up-to-date by considerable refinement of method and by the inclusion of much recent material from anthropology, psychology, and the social sciences. Pepper considers the question of "how to make well-grounded decisions in human affairs". His analysis yields the concept of "selective systems" as the organizing principle of types of value and of value selection. Among these are personal, social, and cultural valuation patterns; the (...) system of natural selection is superimposed upon all the others.--J. F. D. (shrink)

Perforation or gap formation in a vegetation is a major process in landscape transformation. The occurrence of gaps profoundly alters the microclimatical conditions in a vegetation. A method is proposed to quantify perforation by using the three main 2-D characteristics of the gaps: area, number and boundary length. New measures are developed by normalizing the observed values to the reference status of minimum and maximum perforation. As minimum perforation status, the presence of one single gap with area equal to the (...) map resolution is assumed. The new measures are combined using a 3-D Euclidean distance to visualize the process and to detect changes. The method is exemplified using a field case of gaps in a tropical terra firme rainforest at Tiputini, Ecuador. (shrink)

This volume continues the grouping of natural philosophers with cosmological interests and moral philosophers. With the natural philosophers, the contrast is between those who deny that true being can be found in the sensible world and those atomists who react to this monism in favour of the multiplicity of the sensible world. Since the exactly opposite conclusion has been recently maintained, Guthrie's assertion that Parmenides distinguished the concept of eternity from the concept of everlastingness is of particular interest. Of course, (...) Guthrie's acumen and erudition are so well established as to make his projected five volume history of Greek philosophy indispensable for any student—D. J. B. (shrink)

In explicating the terms "Evangelical," "Catholic," and "Reformed," Vassady outlines what he thinks are the essential characteristics of any new Church communion. His analysis generally develops along classical or Neo-Orthodox Protestant lines, as is most obvious in his treatment of the apostolic succession of the episcopacy. The new Church will have a functional episcopacy but "without declaring any particular doctrine of the episcopacy." Given Vassady's theological leanings and conception of the Church, it is somewhat anomalous that he thinks organic unity (...) so highly desirable.—D. J. B. (shrink)

Marsh borrows Richard McKeon's methodological notion of the "problematic" approach to intellectual history. Concentrating on their dialectical character, English criticism from 1650-1800 is explored in the writings of the third Earl of Shaftesbury, Mark Akenside, David Hartley, and James Harris.—D. J. B.

Starting from Plato's statement in the Seventh Letter that Plato never intended to write down his philosophy in systematic form, Sinaiko conceives of the dialogues as attempts to combine the power of the spoken word with the written word while avoiding the limitations of either. Dramatic form and philosophic content are interdependent. The three dialogues are interrogated for statements about dialectic, and each dialogue's account of dialectic is taken to be complete in itself. It is not simply a dialectical method (...) which Plato is using; Being itself is dialectical, and there is no final philosophical system but rather an "infinite multiplicity of systems." While it is certain that philosophy for Plato can not be separated from the activity of philosophizing, Sinaiko's claim is far more controversial: that each dialogue "sets forth a complete ontology, an entire philosophical system." One might well disagree with that contention and other more detailed points of interpretation. But Sinaiko's position is defended ably and his book has a philosophical vitality which sets it apart from the usual pedantic efforts to expose this or that Platonic argument.—D. J. B. (shrink)

Interpreting European reactions to the outside world from the beginning of European history to the end of the nineteenth century, Baudet discusses Utopian literature, the idea of the "noble savage," and the search for the temporal and geographical location of paradise. Baudet argues that the more historically oriented and self-satisfied cultures were less inclined toward a nostalgic paradise. All in all, this is a fascinating little essay in social history.—D. J. B.

Beardsley and Beardsley are to be congratulated for providing a definitively "non-run-of-the-mill" introductory text which is entirely intelligible for the beginner and yet genuinely philosophical in content and presentation. Twelve very well written chapters, each with a bibliography, cover most of the important problems in metaphysics, epistemology, and ethics. The authors even try to convey that philosophy has human and moral relevance beyond game activity. A significant feature of the book is its intelligent and prolonged discussion of religious beliefs. The (...) authors keep their own views well into the background and make good their claim to stimulate the student's own thinking. For that reason, teachers of widely different philosophical persuasions will find this book equally useful. —D. J. B. (shrink)

Using the principles and sometimes the conclusions of his teacher Adolf Stöhr, Cleve insists that he is giving a philosophical interpretation and not simply a philological reconstruction of these Pre-Socratics. The philosophers have been divided into 1) "Religious Reformers", 2) "Philosophers of Nature", 3) "Champions of Culture Politics"—"The Glossomorphics". There will certainly be disagreement on some of Cleve's interpretations but it must be said that Cleve carries through his philosophical reconstruction with admirable lucidity and consistency though, occasionally, some of his (...) criticisms of the "philologists" are rather waspish. Nevertheless, this is a splendid and important study which is a tribute to the author's erudition and insight.—D. J. B. (shrink)

Recent studies using functional magnetic resonance imaging of patients in a vegetative state have raised the possibility that such patients retain some degree of consciousness. In this paper, the ethical implications of such findings are outlined, in particular in relation to decisions about withdrawing life-sustaining treatment. It is sometimes assumed that if there is evidence of consciousness, treatment should not be withdrawn. But, paradoxically, the discovery of consciousness in very severely brain-damaged patients may provide more reason to let them die. (...) Although functional neuroimaging is likely to play an increasing role in the assessment of patients in a vegetative state, caution is needed in the interpretation of neuroimaging findings. (shrink)

Multiple -conclusion logic extends formal logic by allowing arguments to have a set of conclusions instead of a single one, the truth lying somewhere among the conclusions if all the premises are true. The extension opens up interesting possibilities based on the symmetry between premises and conclusions, and can also be used to throw fresh light on the conventional logic and its limitations. This is a sustained study of the subject and is certain to stimulate further research. Part I reworks (...) the fundamental ideas of logic to take account of multiple conclusions, and investigates the connections between multiple - and single - conclusion calculi. Part II draws on graph theory to discuss the form and validity of arguments independently of particular logical systems. Part III contrasts the multiple - and the single - conclusion treatment of one and the same subject, using many-valued logic as the example; and Part IV shows how the methods of 'natural deduction' can be matched by direct proofs using multiple conclusions.

The letter sent by the Royal Society to the London optician, John Marshall, in 1694, commending his new method of grinding, has been reprinted, and referred to, in recent years. However, there has been no comprehensive analysis of the method itself, the letter and the circumstances in which it was written, nor the consequences for trade practices. The significance of the approval by the Royal Society of this innovation and the use of that approbation by John Marshall and other practitioners (...) are examined. Gaps in existing accounts of Marshall's method are partly remedied by supplementing surviving written materials with accounts of contemporary, and present-day, trade practices based on his method. The reasons why Marshall and his contemporaries failed to record his method and specify his improvements are discussed. The reactions of the Spectacle Makers' Company and its more prominent members, both to the innovation itself and to the Royal Society's letter, are analysed. The impact of the new technique on contemporary and later opticians is described. (shrink)

We briefly review the history of de Broglie's notion of the “double solution” and of the ideas which developed from this. We then go on to an extension of these ideas to the many-body system, and bring out the nonlocality implied in such an extension. Finally, we summarize further developments that have stemmed from de Broglie's suggestions.

Background: The traditional approach to resolving ethics concerns may not address underlying organisational issues involved in the evolution of these concerns. This represents a missed opportunity to improve quality of care “upstream”. The purpose of this study was to understand better which organisational issues may contribute to ethics concerns. Methods: Directed content analysis was used to review ethics consultation notes from an academic children’s hospital from 1996 to 2006 (N = 71). The analysis utilised 18 categories of organisational issues derived (...) and modified from published quality improvement protocols. Results: Organisational issues were identified in 68 of the 71 (96%) ethics consult notes across a range of patient settings and reasons for consultation. Thirteen of the 18 categories of organisational issues were identified and there was a median of two organisational issues per consult note. The most frequently identified organisational issues were informal organisational culture (eg, collective practices and approaches to situations with ethical dimensions that are not guided by policy), policies and procedures (eg, staff knows policy and/or procedural guidelines for an ethical concern but do not follow it) and communication (eg, communication about critical information, orders, or hand-offs repeatedly does not occur among services). Conclusions: Organisational issues contribute to ethical concerns that result in clinical ethics consults. Identifying and addressing organisational issues such as informal culture and communication may help decrease the recurrence of future similar ethics concerns. (shrink)

A probability forecast scored ex post using a probability scoring rule (e.g. Brier) is analogous to a risky financial security. With only superficial adaptation, the same economic logic by which securities are valued ex ante – in particular, portfolio theory and the capital asset pricing model (CAPM) – applies to the valuation of probability forecasts. Each available forecast of a given event is valued relative to each other and to the “market” (all available forecasts). A forecast is seen to be (...) more valuable the higher its expected score and the lower the covariance of its score with the market aggregate score. Forecasts that score highly in trials when others do poorly are appreciated more than those with equal success in “easy” trials where most forecasts score well. The CAPM defines economically rational (equilibrium) forecast prices at which forecasters can trade shares in each other’s ex post score – or associated monetary payoff – thereby balancing forecast risk against return and ultimately forming optimally hedged portfolios. Hedging this way offers risk averse forecasters an “honest” alternative to the ruse of reporting conservative probability assessments. (shrink)

PREFACE. THE Author of this very practical treatise on Scotch Loch - Fishing desires clearly that it may be of use to all who had it. He does not pretend to have written anything new, but to have attempted to put what he has to say in as readable a form as possible. Everything in the way of the history and habits of fish has been studiously avoided, and technicalities have been used as sparingly as possible. The writing of this (...) book has afforded him pleasure in his leisure moments, and that pleasure would be much increased if he knew that the perusal of it would create any bond of sympathy between himself and the angling community in general. This section is interleaved with blank shects for the readers notes. The Author need hardly say that any suggestions addressed to the case of the publishers, will meet with consideration in a future edition. We do not pretend to write or enlarge upon a new subject. Much has been said and written-and well said and written too on the art of fishing but loch-fishing has been rather looked upon as a second-rate performance, and to dispel this idea is one of the objects for which this present treatise has been written. Far be it from us to say anything against fishing, lawfully practised in any form but many pent up in our large towns will bear us out when me say that, on the whole, a days loch-fishing is the most convenient. One great matter is, that the loch-fisher is depend- ent on nothing but enough wind to curl the water, -and on a large loch it is very seldom that a dead calm prevails all day, -and can make his arrangements for a day, weeks beforehand whereas the stream- fisher is dependent for a good take on the state of the water and however pleasant and easy it may be for one living near the banks of a good trout stream or river, it is quite another matter to arrange for a days river-fishing, if one is looking forward to a holiday at a date some weeks ahead. Providence may favour the expectant angler with a good day, and the water in order but experience has taught most of us that the good days are in the minority, and that, as is the case with our rapid running streams, -such as many of our northern streams are, -the water is either too large or too small, unless, as previously remarked, you live near at hand, and can catch it at its best. A common belief in regard to loch-fishing is, that the tyro and the experienced angler have nearly the same chance in fishing, -the one from the stern and the other from the bow of the same boat. Of all the absurd beliefs as to loch-fishing, this is one of the most absurd. Try it. Give the tyro either end of the boat he likes give him a cast of ally flies he may fancy, or even a cast similar to those which a crack may be using and if he catches one for every three the other has, he may consider himself very lucky. Of course there are lochs where the fish are not abundant, and a beginner may come across as many as an older fisher but we speak of lochs where there are fish to be caught, and where each has a fair chance. Again, it is said that the boatman has as much to do with catching trout in a loch as the angler. Well, we dont deny that. In an untried loch it is necessary to have the guidance of a good boatman but the same argument holds good as to stream-fishing... (shrink)
