This paper investigates connectionism's potential to solve the frame problem. The frame problem arises in the context of modelling the human ability to see the relevant consequences of events in a situation. It has been claimed to be unsolvable for classical cognitive science, but easily manageable for connectionism. We will focus on a representational approach to the frame problem which advocates the use of intrinsic representations. We argue that although connectionism's distributed representations may look promising from this perspective, doubts can (...) be raised about the potential of distributed representations to allow large amounts of complexly structured information to be adequately encoded and processed. It is questionable whether connectionist models that are claimed to effectively represent structured information can be scaled up to a realistic extent. We conclude that the frame problem provides a difficulty to connectionism that is no less serious than the obstacle it constitutes for classical cognitive science. (shrink)

It should be clear that Lyell's scientific contemporaries would hardly have agreed with Robert Munro's remark that Antiquity of Man created a full-fledged discipline. Only later historians have judged the work a synthesis; those closer to the discoveries and events saw it as a compilation — perhaps a “capital compilation,”95 but a compilation none the less. Its heterogeneity made it difficult to judge as a unity, and most reviewers, like Forbes, concentrated on the first part of Lyell's trilogy. The chapters (...) on glaciation were admired by Lyell's friends but had relatively little appeal to more general readers. His discussion of the species question hedged far too much to please those who accepted the cogency of Darwin's evidence and arguments. This last section of the book blatantly lacks originality or commitment and certainly has no claim to classical status in anthropology.We are left, then, with the first twelve chapters, for it was this portion that dictated the book's title and that amassed the available evidence favoring the antiquity of the human species. Did it do anything more than marshall the evidence that others had discovered? I think not. Lyell could write with style and verve. Principles of Geology is a remarkably readable book. But Antiquity is the work of a geologist, not of a systematic student of man. Despite its occasional touches of power, it never captures the freshness and immediacy of Lubbock's Pre-historic Times nor the theoretical brilliance of E. B. Tylor's Researches into the Early History of Mankind (1865).96 Antiquity utilizes little of the comparative method whereby Lyell's contemporaries used data from modern “savagery” to elaborate the possible social functions of the prehistoric remains being uncovered. It contains little social theory and has virtually no integrated framework. Even the first twelve chapters do not really hang together. As Hooker, commenting to Darwin on Lubbock's review, sadly wrote: “Lubbock in [the] N[atural] H[istory] Review, had in a note called attention to Lyell's ... ‘doing injustice’ to Prestwich & Falconer. I modified this expression ‘injustice’ in Lubbock's paper (which was friendly and apologetic). I am deeply sorry for it, but what can one do? I do think Lyell's first XII chapters a complete mess.”97 In another letter to Darwin, Hooker described this first portion of Antiquity as “confused and confusing.”98Part of the problem, of course, lay in the subject's novelty for Lyell and for most of his contemporaries. At a deeper level, however, I believe that the book accurately reflects Lyell's uncertainties about Darwin's work and its implications for man.99 Leonard Wilson's edition of Lyell's Scientific Journals provides a unique insight into Lyell's mind during the years just before he began to write Antiquity.100 Preoccupied with the human implications of evolutionary biology, Lyell was not clear how many of those implications were compatible with his deep convictions about the dignity of man's place in the cosmos. With a certain naiveté, Lyell complained in 1873 that many of his readers had failed to see the “natural connections” among the three portions of Antiquity.101 Connections could indeed be drawn between man's antiquity and his evolutionary origins; Lyell's private Scientific Journals movingly demonstrate that he was well aware of this fact. But he never fully made the connections in his published writings. Antiquity of Man is more appropriately seen as the last gasp of the heroic period in British geology than as the opening salvo in a new, post-Darwinian anthropological synthesis. Between the founding of the Geological Society of London in 1807 and the middle of the nineteenth century, geology was recognized as one of the most exciting and innovative scientific fields in Britain.102 Lyell himself had contributed much to that drama, and by the 1860's he was a public figure of venerable proportions. More then any other man he represented a geology that had extended the boundaries of process, time, and life. The fundamental achievements of Lyell and his colleagues had been assimilated into the wider Victorian consciousness, yet the earlier public debates about “genesis and geology” had left untouched in its essentials the concept of Man as a moral, responsible, created being.103Lyell never abandoned this view of his own species, and in 1863 it was a completely responsible creature which, under the weight of empirical evidence, Lyell admitted had lived on earth far longer than had previously been thought. Certainly this more generous allowance for human existence was constitutive to what Burrow calls the evolutionary social theory of midcentury Britain.104 Unlike Lyell, the younger representatives of this anthropology quietly accepted both man's antiquity and his aboriginal animality. Herbert Spencer's Principles of Psychology (1855), as well as the other volumes of his grand Synthetic Philosophy, presented as part of the cosmic process the development of human from prehuman beings.105 Tylor's discussion of what in his Researches (1865) he called the “gesture-language” presupposed the gradual and de novo origin of language in early human populations.106 Lubbock's young and polished mind was untroubled by the human implications of Darwin's work, and he cast his Prehistoric Times into such a perfect mold that it and its companionpiece (On the Origin of Civilization, 1870) went through seven editions each between 1865 and World War I, with their original theoretical structures intact. In a way that Lyell could not grasp, Lubbock was intrigued by questions concerning the origins of moral and religious beliefs and did not flinch at the thought of an amoral, atheistic creature as an ancestor.107 Indeed, as the German naturalist Carl Vogt pointed out in his Lectures on Man, translated into English the year after Antiquity, both Darwin's theories and the primitive flint knives of the Stone Age bore witness to a time beyond that imaginable from the condition of the lowest present-day “savage”:From such a low condition [little better than anthropomorphous apes], compared to which that of the so-called savages of the old and new world is a refined civilisation, has the human species gradually extricated itself, in a bitter struggle for existence, which it was well able to maintain, by being gifted with a larger amount of brain and intelligence than that possessed by the surrounding animal world.108The easy integration of biological and social themes was perhaps the distinguishing hallmark of Victorian anthropology of the 1850's and 1860's. After his fashion, Lyell got both themes into Antiquity, but he carefully separated them with a seven-chapter wall of glacial ice. Lyell's anthropology was not that of a thoroughgoing evolutionist like Lubbock, Tylor, or Spencer. For Lyell prehistoric man was not a product of biological evolution. Rude and superstitious he may have been, but he possessed ritual and a belief in a future state, and thus deserved “the epithet of ‘noble,’ which Dryden gave to what he seems to have pictured to himself as the primitive condition of our race: as Nature first made man/when wild in woods the noble savage ran.”109As a systematic argument, Lyell's book was at best a significant failure. As a popularization, it was a success — largely because of the personal stature of its author and the particular moment of its appearance. It helped establish the fact of man's antiquity with a wider Victorian audience, in itself no mean achievement. But Lyell was unable to exploit the fuller implications of his material in the service of a secular science of man. Ironically, he exploited only his colleagues' discoveries. Though the aging Lyell, with failing eyesight but unfailing mental powers, can still be seen as a man of considerable importance, his Antiquity belongs to the carefully circumscribed world of British geology rather than to the less disciplined world of Victorian anthropology.

In the course of a series of arguments to refute Simmias' hypothesis that soul is an attunement Socrates asks the question , which may be literally translated ‘Is it not natural for each attunement to be an attunement according as it has been attuned?’ This question Simmias admits he does not understand, and Socrates responds with another question in which he suggests that if it is more attuned and to a greater extent, supposing that it is possible for this to (...) happen, it would be more of an attunement and a greater attunement, if less attuned and to a smaller extent, less of an attunement and a smaller attunement .if less attuned and to a smaller extent, less of an attunement and a smaller attunement . Neither the meaning of these questions nor their place in the argument is at all obvious, and none of the solutions offered by the English commentators seems to be without difficulty. (shrink)

The various discussions on morals which have recently appeared in the pages of this journal, like most modern discussions of the subject, have had to concern themselves with two antitheses, between the good and the right, and between duty and interest. As to the first, is the good what it is because it is right, or is right what it is because it is good? Or may the two be distinct, so that what is right is not necessarily good? And (...) if it is not good, is it bad? Or do the right and the good overlap? For the second, the antithesis between duty and interest—“of course,” says one, “the two have nothing to do with one another; the more carefully we keep them apart, the better.” In rare instances, indeed, it will be allowed that my duty may coincide with my interest; but when it does so, it is felt to be shorn of half its worth. If it pays me to tell the truth, what thank have I for all my veracity? (shrink)

In this module, which first appeared in Vol. 9, Nos. 2&3, pp. 168-170, 1989, an error in a formula appeared three times: CO2 and C2HSOH should read CO2. The entire article is reprinted here. The editors apoligize for this and regret any confusion this may have caused.

Originally published in 1985, this distinguished and constructive critique of modern culture introduced into our language a brand-new term, ‘PN’, standing for ‘psychic nutrition’, which at the time promised to become a household expression. Drawing on his first-hand knowledge of oriental civilizations; on discoveries of Jung, especially his concept of psychic energy; on the ideas of the cultural anthropologists; and not least on the New Science implicit in microphysics and microbiology, E.W.F. Tomlin, whose philosophical books have been translated into several (...) languages, shows how the human psyche requires its own kind of nourishment just as urgently as the body needs food. In the industrial societies of the West, this need has often been ignored. Reformers, in their earnest though sometimes inept endeavours to create a better world, have too often exposed us to the dangers of psychic starvation and the noxious effects of what may be called ‘neg-PN’. Here lie the roots of violence and the lack of direction so conspicuously afflicting modern man and woman. Examples of PN, positive and negative, are given, lending the book an immediacy and practical character often lacking in studies of this kind. In the new scientific approach here adopted, the divisions between matter and life, and life and mind, are discarded, and the old conflict between science and religion shown to belong to an out-of-date world view. The result is a radical reappraisal of the nature and function of religion and art, the two great psychic forces in history. Indeed, the present crisis is shown to originate in the psychic sphere rather than in the political and economic order. Deeply felt and elegantly written, yet not lacking in wit and humour, the book ends with some concrete ideas on how a more balanced culture may be achieved. (shrink)

The current study is a pilot trial to examine the effects of a nonelective, classroom-based, teacher-implemented, mindfulness meditation intervention on standard clinical measures of mental health and affect in middle school children. A total of 101 healthy sixth-grade students (55 boys, 46 girls) were randomized to either an Asian history course with daily mindfulness meditation practice (intervention group) or an African history course with a matched experiential activity (active control group). Self-reported measures included the Youth Self Report (YSR), a modified (...) Spielberger State-Trait Anxiety Inventory, and the Cognitive and Affective Mindfulness Measure –Revised. Both groups decreased significantly on clinical syndrome subscales and affect but did not differ in the extent of their improvements. Meditators were significantly less likely to develop suicidal ideation or thoughts of self-harm than controls. These results suggest that mindfulness training may yield both unique and non-specific benefits that are shared by other novel activities. (shrink)

The practice of critical care medicine has long been a difficult task for most critical care physicians in the densely populated city of Hong Kong, where we face limited resources and a limited number of intensive care beds. Our triage decisions are largely based on the potential of functional reversibility of the patients. Provision of graded care beds may help to relieve some of the demands on the intensive care beds. Decisions to forego futile medical treatment are frequently physician-guided family-based (...) decisions, which is quite contrary to the Western focus on patient autonomy. However, as people acquire knowledge about health care and they become more aware of individual rights, our critical care doctors will be able to narrow the gaps between the dif ferent concepts of medical ethics among our professionals as well as in our society. An open and caring attitude from our intensivists will be important in minimizing the cross-cultural conflict on the complex issue of medical futility. (shrink)

Computable structures of Scott rank ${\omega_1^{CK}}$ are an important boundary case for structural complexity. While every countable structure is determined, up to isomorphism, by a sentence of ${\mathcal{L}_{\omega_1 \omega}}$ , this sentence may not be computable. We give examples, in several familiar classes of structures, of computable structures with Scott rank ${\omega_1^{CK}}$ whose computable infinitary theories are each ${\aleph_0}$ -categorical. General conditions are given, covering many known methods for constructing computable structures with Scott rank ${\omega_1^{CK}}$ , which guarantee that the (...) resulting structure is a model of an ${\aleph_0}$ -categorical computable infinitary theory.

My apology for reverting to this subject is a recent article by Mr. W. C. F. Walters in the April number of the Classical Quarterly for 1910 on the signatures in the Vatican Codex . Mr. Walters does not seem to have been aware that this manuscript, though not of direct value in the constitution of the text of Livy, is one whose interest from a palaeographical point of view has long been recognized. A number of articles have been written (...) concerning it, most of which deal with the signatures, the subject of Mr. Walters' paper, more fully and more accurately than he has done. Beyond giving the signatures, two of them incorrectly, Walters does nothing more than to conclude that there were eight scribes, who copied 42 quaternions. But a great deal more than this is known about the scribes and the manuscript. In fact, thanks to the ingenious combinations of Chatelain and Traube in piecing together the hints suggested by the signatures, more is known about this particular manuscript and the circumstances under which it was made than is the case with any other manuscript of a classical author of so early a date. It may therefore be worth while to summarize the known data concerning the manuscript, with a brief account of how they were worked out, referring the reader for the details to the articles mentioned in the footnotes.

Tarán’s case against the authenticity of Epinomis depends on the claim that it is incompatible with Plato’s Laws. Behind this claim is the uncritical assumption that the Athenian Stranger of Laws speaks for Plato. While the Athenian Stranger of Epinomis clearly does not do so, the same is equally true, albeit more difficult to detect, of the Stranger in Laws. Once the Athenian is recognized as both ambitious and impious, a reconstruction of the last sentence of Epinomis — on which (...) Tarán’s incompatibility thesis principally rests — reveals the theological-political continuity between the two dialogues: the Stranger is intent on bringing the city into being while securing divine sanction for his own code of laws and divine honours for himself. Plato appended the Epinomis to the Laws in order to make it easier for the student to recognize the Stranger’s intentions as well as to draw attention to Book VII of the Laws, the centre of the dialogue once Epinomis is recognized as its thirteenth book; it is here that the Stranger describes how a mathematical and astronomical man may become a god to other men.

Polybius' sources for his account of the First Punic War are not in question. It is agreed that Fabius Pictor and Philinus of Agrigentum, whom he criticizes didactically in i. 14–15, were his sole authorities. But, as Gelzer has most recently pointed out,1 difficulties soon appear when one begins to assign the various sections of the narrative to one or other of Polybius' predecessors. This task has frequently been attempted, and a good deal of common ground has been won. It (...) is not my purpose in this paper to go over that ground again. What I propose to do is, first, to discuss the most recent article on Philinus of Agrigentum, which is in my opinion based on false principles and comes to novel, but wrong, conclusions; this done I shall try to relate what can be discovered with certainty about the character of Philinus' work to the general body of Hellenistic historical writing and historical theory. I hope that such a study may help to throw light on one part of Polybius' direct literary inheritance. (shrink)

Hamiltonian light-front dynamics of quantum fields may provide a useful approach to systematic nonperturbative approximations to quantum field theories. We investigate inequivalent Hilbert-space representations of the light-front field algebra in which the stability group of the light front is implemented by unitary transformations. The Hilbert space representation of states is generated by the operator algebra from the vacuum state. There is a large class of vacuum states besides the Fock vacuum which meet all the invariance requirements. The light-front Hamiltonian must (...) annihilate the vacuum and have a positive spectrum. We exhibit relations of the Hamiltonian to the nontrivial vacuum structure. (shrink)

There is a growing literature on the concept of e-trust and on the feasibility and advisability of “trusting” artificial agents. In this paper we present an object-oriented model for thinking about trust in both face-to-face and digitally mediated environments. We review important recent contributions to this literature regarding e-trust in conjunction with presenting our model. We identify three important types of trust interactions and examine trust from the perspective of a software developer. Too often, the primary focus of research in (...) this area has been on the artificial agents and the humans they may encounter after they are deployed. We contend that the humans who design, implement, and deploy the artificial agents are crucial to any discussion of e-trust and to understanding the distinctions among the concepts of trust, e-trust and face-to-face trust.

Many individuals with developmental language disorder (DLD) and individuals who are deaf or hard of hearing (D/HH) have social–emotional problems, such as social difficulties, and show signs of aggression, depression, and anxiety. These problems can be partly associated with their executive functions (EFs) and theory of mind (ToM). The difficulties of both groups in EF and ToM may in turn be related to self-directed speech (i.e., overt or covert speech that is directed at the self). Self-directed speech is thought to (...) allow for the construction of non-sensory representations (i.e., representations that do not coincide with direct observation). Such non-sensory representations allow individuals to overcome the limits set upon them by the senses. This ability is constrained by the development of word meaning structure (i.e., the way words are understood). We argue that the greater ability to construct non-sensory representations may result in more enhanced forms of EF and ToM. We conclude that difficulties in EF, ToM, and social–emotional functioning in those with hearing and language problems may be accounted for in terms of word meaning impairments. We propose that word meaning structure and self-directed speech should be considered in assigning EF and ToM treatments to individuals with DLD and those who are D/HH. (shrink)

Recently, Australia became the second jurisdiction worldwide to legalize the use of mitochondrial donation technology. The Mitochondrial Donation Law Reform (Maeve’s Law) Bill 2021 allows individuals with a family history of mitochondrial disease to access assisted reproductive techniques that prevent the inheritance of mitochondrial disease. Using inductive content analysis, we assessed submissions sent to the Senate Committee as part of a programme of scientific inquiry and public consultation that informed drafting of the Bill. These submissions discussed a range of bioethical (...) and legal considerations of central importance to the political debate. Significantly, submissions from those with a first-hand experience of mitochondrial disease, including clinicians and those with a family history of mitochondrial disease, were in strong support of this legislation. Those in support of the Bill commended the two-staged approach and rigorous licencing requirements as part of the Bill’s implementation strategy. Submissions which outlined arguments against the legislation either opposed the use of these techniques in general or opposed aspects of the implementation strategy in Australia. These findings offer a window into the ethical arguments and perspectives that matter most to those Australians who took part in the Senate inquiry into mitochondrial donation. The insights garnered from these submissions may be used to help refine policy and guidelines as the field progresses. (shrink)

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

In the current career landscape and labor market, career transitions have become a critical aspect of career development and are significant for Human Resource Development research and practice. Our research examines the type of support used during different career transitions and who can provide that support to women in career transition. We investigated four types of social support—emotional, appraisal, informational, and instrumental—and their roles in five types of career transitions: school-to-work transition, upward mobility transition, transition to a new profession, transition (...) to entrepreneurship, career re-entry transition, and transition to retirement. We analyzed 80 journal articles using directed content analysis, cross-tabulation, and nonparametric statistical tests. Instrumental support appears to be the most commonly documented type of social support in this career transition literature. Appraisal support was consistently documented least for each type of career transition. Our results may highlight the importance of personal connections and internal resources in successful career transitions for women. Based on our findings, we offer a model of women's social support network for career transitions and advocate for expanded networks of social support for women anticipating and during career transitions. The results of our study contain insights for how women can be supported in transitioning to the next career experience. We conclude with suggestions for future research. (shrink)

Genomics provides information on genetic susceptibility to diseases and new possibilities for interventions which can fundamentally alter the design of fair health policies. The aim of this paper is to explore implications of genomics from the perspective of equal opportunity ethics. The ideal of equal opportunity requires that individuals are held responsible for some, but not all, factors that affect their health. Informational problems, however, often make it difficult to implement the ideal of equal opportunity in the context of healthcare. (...) In this paper, examples are considered of how new genetic information may affect the way individual responsibility for choice is assigned. It is also argued that genomics may result in relocation of the responsibility cut by providing both new information and new technology. Finally, how genomics may affect healthcare policies and the market for health insurance is discussed. (shrink)

This book contains three essays: "The Mask and the Face: The Perception of Physiognomic Likeness in Life and Art" by Gombrich, the renowned art historian and critic; "The Representation of Things and People" by psychologist, Julian Hochberg; and "How Do Pictures Represent" by philosopher, Max Black. The book is based upon lectures delivered in the Johns Hopkins 1970 Thalheimer Lectures, where, taking off from the question "how there can be an underlying identity in the manifold and changing facial expression of (...) a single individual," there is an interdisciplinary attempt at clarifying the problem of representation. Gombrich’s central thesis is that the key to artistic representation is empathy and projection, which is guided by the interlocking display of the permanent and mobile features of the object represented. Perceptual activity and empathy rely more on the muscular imitation than on passive visual reception. He holds that what is singled out as the likeness-factor uniting the permanent and mobile features in, for example, the photograph of the four-year old Lord Russell and such factors in the ninety-year old Russell is the "general tonus, the melody of transition from given ranges of relaxations to forms of tenseness." Hochberg’s essay spells out the position that perception is purposive behavior, wherein the purpose is the information sought and behavior is the "succession of glances in different directions." Holding that perceptual activity is grounded in expectations, he lays aside Gombrich’s muscularity-thesis in favor of a learned expectation of feature characteristics. Black’s essay is a conceptual analysis of "depiction," or more precisely, of "P displays a subject S if and only if R, where R ‘will constitute the necessary and sufficient condition for P displaying S'." The essay, which proceeds in a Wittgensteinian Investigations-type fashion ends where the reader would hope it begin. He concludes that the problem can only be adequately answered by moving from logical investigation to the world of the artisan and art lover. To arrive at this conclusion he debunks six candidates that claim to meet the depiction conditions: causal history, selective information, intention, mimesis, resemblance, and "looking-like." At best, depiction may be considered a "cluster" concept of all six. Further determination, he holds, requires knowledge of the purpose of a particular depiction, and this takes us out of logic and into art; and so Black stops, unfortunately.—W. A. F. (shrink)

With the publication of these two volumes the ground has now been prepared for a long awaited event, the critical edition of the works of Henry of Ghent. Henry was one of the outstanding philosophizing-theologians at the University of Paris in the second half of the thirteenth century and, during the period between the death of Thomas Aquinas in 1274 and the ascendancy of John Duns Scotus near the beginning of the fourteenth century, no other Master surpassed him in terms (...) of influence or importance. During his tenure there as Master in the theology faculty, Henry conducted fifteen Quodlibetal disputes. His written versions of these, along with his Summa of ordinary Disputed Questions, constitute his most important surviving works. And of these, his Quodlibets rank first. Henry's philosophical and theological views were highly original and drew considerable reaction from other leading Masters of the time, especially from Giles of Rome, Godfrey of Fontaines, and somewhat later, from Duns Scotus. While his personal thought cannot be reduced to that of any earlier thinker or tradition, his views were heavily influenced by Augustine, by Avicenna, and by various other Neoplatonic currents. At the same time, while he was quite familiar with the texts and thought of Aristotle, he reacted strongly against the more radical form of Aristotelianism developed by Siger of Brabant, Boethius of Dacia, and other Masters in the Arts Faculty at Paris in the 1260s and 1270s. Aquinas's incorporation of many Aristotelian positions into his own thought was also suspect in Henry's eyes. Given this background, Henry himself may be regarded as an outstanding representative of the Neo-Augustinian philosophical current which surfaced at Paris around 1270, which triumphed with the condemnation of 219 propositions by Stephen Tempier, Bishop of Paris, in 1277, and which would continue to be a dominant philosophical force until the end of the century. The need for a critical edition of his Quodlibets and his Summa has long been recognized, since the only printed versions date from the sixteenth and seventeenth centuries. In these first two volumes of Henry's Opera omnia Macken has prepared the way for the critical edition of Henry's works and especially of his Quodlibets. Here one finds a valuable catalog, based on first-hand inspection, of the widely scattered manuscripts of Henry's works. The catalog also contains expert codicological descriptions of the contents of these manuscripts, including works whose authenticity remains doubtful. Manuscripts are also considered which contain works that treat ex professo of Henry's doctrine. This is followed by an appendix which surveys ancient references to other manuscripts allegedly containing Henry's works, which manuscripts have not yet been found. Then there is a Répertoire, not of manuscripts but of Henry's works themselves, including certainly authentic works, works of doubtful authenticity, and finally, in another short appendix, works which have been falsely ascribed to him. A third part of this survey of Henry's works is devoted to manuscripts of other writers who discuss Henry's doctrine ex professo. The two volumes conclude with all the necessary indices. One must congratulate Macken for the care, the industry, and the meticulous scholarship with which he has prepared these two volumes. Not only are they of great value to anyone interested in the manuscript tradition of Henry's works and doctrine; they also include helpful descriptions of the writings of many other medieval authors which are contained in many of these same manuscripts. They will undoubtedly be carefully combed for decades to come by other scholars interested in these same authors and manuscripts. These volumes will be indispensable for libraries of institutions making any serious claim to expertise in the history of medieval philosophical and theological thought. One can only wish Macken and his international team of collaborators every success in their next immediate task, the actual edition of Henry's most important works, his fifteen Quodlibetal Questions.--J.F.W.

No. 20 in the Marquette series "Mediaecal [[sic]] Philosophical Texts in Translation," this translation is based on J. R. O’Donnell’s edition of the only extant manuscript of the Universal Treatise, and is preceded by a helpful introduction of 28 pp. plus a selected bibliography. An English version of this work should be welcomed by scholars not versed in Latin who are nonetheless interested in Nicholas’ thought, whether because of his highly critical reactions to Aristotle and Averroes or because of certain (...) similarities between his philosophical views and those of Hume. If the latter are primarily to be found in his two extant letters to Bernard of Arezzo, the former constitute the very heart of this work. It should also be noted that the Universal Treatise was originally intended to recall university professors, especially at Paris, to the study of Christianity and ethics. Written c. 1340, its attacks on Aristotle and Averroes were intended to contribute to this purpose. Nevertheless, some of the positions expressed therein were to bring Nicholas himself into conflict with ecclesiastical authority. Not least among these troublesome views from the standpoint of religious orthodoxy was the suggestion that all things are eternal. The situation was further complicated by Nicholas’ contention that not all the views found in the Treatise represent his own convictions. Many are to be taken as probable or more probable. In his attacks on Aristotle and Averroes he does not claim to disprove demonstratively what they held, but only to show that their opinions are less probable than those he advances. Granted that the chief unifying factor in this work is negative, its anti-Aristotelian and anti-Averroistic thrust, yet, as is suggested in the introduction, some kind of positive unifying theme is also at work, Nicholas’ view of the good. Since the universe must always contain the same amount of goodness, everything in it must remain in existence. Therefore the universe consists of unchangeable atoms. From this atomism follows the view that space consists of points and time of instants. Since change in quantity and place cannot produce or destroy real being, Nicholas must therefore hold that quantity is really identical with material substance and that movement is nothing but change in the position of atoms. Moreover, if things are eternal, it is probable that the same holds for the actions of the soul. As eternal such acts remain unchanged and hence do not vary in degree of intensity. They simply pass from person to person. Consequently, the same object cannot be seen clearly and obscurely. Nicholas also suggests that all things are as they appear, granted that such must be accepted not because it has been proved but because this conviction gives pleasure to the mind. Again, he argues that since a cause can produce only one kind of effect, not all things have been produced by God whether as their total or as their partial cause. He then suggests that because God’s power is infinite, no effect can be produced by him naturally. As finite such an effect would not be proportioned to his infinite power. His arguments against any kind of Averroistic theory of one separate intellect for all mankind are both interesting and unusual. In fact he appears to go to the opposite extreme, not only defending individual intellects for individual men but also suggesting that in one and the same soul there are as many intellects as concepts. That Nicholas himself saw some difficulties with this position may be inferred from his admonition that further thought be given to this matter. If the same might be said of other unusual theories advanced in the Treatise, its translators are to be commended for having made it available to English language readers.—J. F. W. (shrink)

This is a new critical latin edition, with facing English translation, of Peter Abelard’s ethical treatise, sometimes entitled "Know Thyself." The book is one in the series of Oxford Medieval Texts. Accompanying the latin text and simple, easy reading translation is a most helpful introduction by Luscombe which points out the historical importance of this little treatise as among the first finely articulated attempts at bringing the classical concerns with human virtues and character together with the theological concerns of a (...) believing Christian. Ethics deals with the problem of how we may properly speak of the moral formation of a person. Abelard’s treatment is more weighted toward the attitudes of man than the nature of his deeds. What is worked out, with the help of many suggestive examples and frequent reference to the religious practices of the twelfth-century church, is a crucial theory of intention and a definition of sin. He holds that our intention, measured to the standards of divine law, determines the morality of our actions : "We consider morals to be the vices or virtues of the mind which make us prone to good or bad works." Good and bad emerge from the struggle where there is consent to an act virtuously or viciously motivated. Morality does not come from the inclination since the constitution of man includes both his virtues and his vices; nor does it come from his acts since all acts are indifferent, before God, to good or bad. It is the intent or consent to act that is determinant. Sin, the other major theme, complementary to intention, is defined as contempt for God, i.e., "to do by no means on his account what we believe we ought to do for him." He founds his notions of morality on God as that good, the source and whole, such that "although... there is a number of good things so that goodness exists in plurality, it does not follow therefore that goodness is greater." By working out these notions, Abelard delivers an innovative morality of conduct for a man beset with a character marked with both virtues and vices, emphasizing man’s faculty of choice and underscoring his ability to know and be responsible to the divine law. Besides the introduction and text, Luscombe has included a description of the manuscripts used in preparing the text and indices of quotations, allusions, and manuscripts.—W. A. F. (shrink)

The study of mental illness by the methods of molecular genetics is still in its infancy, but the use of genetic markers in psychiatry may potentially lead to a Virchowian revolution in the conception of mental illness. Genetic markers may define novel clusters of patients having diverse clinical presentations but sharing a common genetic and mechanistic basis. Such clusters may differ radically from the conventional classification schemes of psychiatric illness. However, the reduction of even relatively simple Mendelian phenomena to molecular (...) genetics has been shown to be a surprisingly complex and problematic enterprise. Mental illnesses exist at many levels of including social, environmental, and developmental interactions. Reductionistic shifts in the classification of such a disease entity will have to address the interlevel dynamics that take place within the structure of theories of mental illness. The question of how molecular analysis of psychiatric disease will impact on the structure of existing theories and classification systems is the central topic of this paper. (shrink)

Despite the importance of extrapair copulation (EPC) in human evolution, almost nothing is known about the design features of EPC detection mechanisms. We tested for sex differences in EPC inference-making mechanisms in a sample of 203 young couples. Men made more accurate inferences (φmen = 0.66, φwomen = 0.46), and the ratio of positive errors to negative errors was higher for men than for women (1.22 vs. 0.18). Since some may have been reluctant to admit EPC behavior, we modeled how (...) underreporting could have influenced these results. These analyses indicated that it would take highly sex-differentiated levels of underreporting by subjects with trusting partners for there to be no real sex difference. Further analyses indicated that men may be less willing to harbor unresolved suspicions about their partners’ EPC behavior, which may explain the sex difference in accuracy. Finally, we estimated that women underreported their own EPC behavior (10%) more than men (0%). (shrink)

Two decades of research using repeated false statements and underhanded information have shown that people can easily be made to believe that they have seen or experienced something they never did. In this paper, we discuss the possibility that the mental health professional and client may unknowingly collaborate to create a client′s false memory of childhood sexual abuse. Both therapist and client bring beliefs into therapy, and the confirmation bias shows that people discover what they already believe to be true. (...) What do people believe about memory? We asked 115 students for their reactions to various statements about how memory works; results showed widespread belief in the repression mechanism. A principal components analysis revealed that three larger beliefs explained 61% of the variance in the more specific beliefs: possible sources of memory distortions, memory for traumatic events, and the potential recoverability of memories. Finally, we discuss the ambiguity inherent in the term repression, as well as the generalizability of misinformation research to the repressed and recovered memories. (shrink)

As Raymond Williams famously declared, nature is one of the most complex words in the English language – and, we may confidently predict, its Germanic relatives including Dutch. The workshop that took place in June 2007 in the Netherlands, from which this volume is derived, was based on an earlier program exploring connections between our concepts of nature and related concepts of science and religion. Though one may not immediately expect these three realms to be interrelated, countless examples suggest otherwise.

The claims that Dr. F. H. George makes on behalf of his machines are obscurely stated. Does he claim that a machine has been made and has actually produced a kind of response which is incalculable, given the specification to which it has been built and also the prescribed conditions, what is put in for the particular performance in question? “Incalculable” does not mean that nobody has bothered to calculate, but that somebody has bothered, that the calculations show that the (...) response in question is not among the calculated ones, that it is not chance or mechanical breakdown, but a specific response to something specific among the given conditions. If he could substantiate this claim, then I would reluctantly agree that some machines are cleverer and more thoughtful than I thought possible, and some men sillier and less thoughtful, for they deliberately design machines to do they know not what.

Colour constancy refers to the ability to extract information about surface colours independently of illumination conditions. A ripe strawberry, for example, appears the same red when viewed under a blue sky or a reddish sunset. Since Land's pioneering work, discussion has centred on the issue whether colour constancy is achieved primarily in the retina or visual cortex. Recently, the debate has shifted to a consideration of the constraints imposed by various psychophysical tasks and instructions. Humans can judge illuminant colour, reflected-light (...) colour, surface colour, and the relationship between surface colours within a scene. Such observations suggest that colour constancy may not be a unitary phenomenon, and that its different aspects may be mediated at different levels in the visual system. Several questions therefore arise: are the tasks of surface estimation and illuminant estimation complementary, insofar as good performance in one implies poor performance in the other? How does retinal adaptation alter performance? Is colour vision tuned to the statistical composition of natural surfaces and illuminants? What role does colour-opponent processing in retina and cortex play in colour constancy? These and related questions are explored here in order to better understand what we mean when we ask: "Why do strawberries look red?". (shrink)

This article is an attempt to evaluate the Oregon plan from the perspective of a Scandinavian national health care system. The Nordic welfare states are marked by a strong emphasis on equality. As an example of an egalitarian system we present the Norwegian health care model in part one. In part two, the arguments in favor of a one tier system in Norway are presented and compared to Oregon's two tier system. Although we argue, in part three, that a comparison (...) of the degree of explicitness in the prioritization process shows that Norway has much to learn from Oregon, we do believe that the Norwegian system has some attractive elements that may function as an important corrective. In part four we present the Norwegian Guidelines for priority-setting and discuss the weight assigned to the severity of disease criterion. It is argued that the exclusion of information about the severity of disease partly explains the counterintuitive ranking of treatment-condition pairs in Oregon's initial method based on the principle of health maximization. A normative analysis of the conflicting norms of efficiency and equality of results is called for. The final part of the paper is devoted to the problem of rigidity. Henry J. Aaron has argued that the Oregon system is insensitive to inter-individual variations within each diagnosis-treatment pair. This objection is a severe one, since the system might end up treating patients unfairly on the individual level. To overcome this problem, we suggest a selection rule that should be more capable of dealing with the problem of rigidity. (shrink)

Monetary intelligence theory asserts that individuals apply their money attitude to frame critical concerns in the context and strategically select certain options to achieve financial goals and ultimate happiness. This study explores the dark side of monetary Intelligence and behavioral economics—dishonesty. Dishonesty, a risky prospect, involves cost–benefit analysis of self-interest. We frame good or bad barrels in the environmental context as a proxy of high or low probability of getting caught for dishonesty, respectively. We theorize: The magnitude and intensity of (...) the relationship between love of money and dishonest prospect may reveal how individuals frame dishonesty in the context of two levels of subjective norm—perceived corporate ethical values at the micro-level and Corruption Perceptions Index at the macro-level, collected from multiple sources. Based on 6382 managers in 31 geopolitical entities across six continents, our cross-level three-way interaction effect illustrates: As expected, managers in good barrels, mixed barrels, and bad barrels display low, medium, and high magnitude of dishonesty, respectively. With high CEV, the intensity is the same across cultures. With low CEV, the intensity of dishonesty is the highest in high CPI entities —the Enron Effect, but the lowest in low CPI entities. CPI has a strong impact on the magnitude of dishonesty, whereas CEV has a strong impact on the intensity of dishonesty. We demonstrate dishonesty in light of monetary values and two frames of social norm, revealing critical implications to the field of behavioral economics and business ethics. (shrink)

Thanks to developments in genomics,dietary recommendations adapted to genetic riskprofiles of individual persons are no longerscience fiction. But what are the consequencesof these diets? An examination of possibleimpacts of genetically tailor-made diets raisesmorally relevant concerns that are analogous to(medical-ethical) considerations aboutscreening and testing. These concerns oftengive rise to applying norms for informedconsent and for the weighing of burdens andbenefits. These diets also have a broaderimpact, especially because food patterns arefull of personal, social and cultural meanings.Diets will change one's food patterns (...) and one'sattitude towards food, and this may implychanges in one's identity. We argue that suchan impact does not necessarily raise moralproblems. Moral concerns are, however, relevantif collective values and shared meanings infood practices are at issue. Therefore, thedevelopment of genetically tailor-made dietsdoes not merely require emphasis on weighingpersonal benefits and burdens and on informedconsent. It also asks for attention to andmoral reflection on the collective valuesinvolved in food practices. (shrink)

Group selection, as advocated by Sober and Wilson, is theoretically plausible, although it remains an open question as to what extent it occurs in nature. If group selection has operated in hominids, it is likely to have selected cultural not genetic variation. A focus on niche construction helps delineate the conditions under which cooperation is favoured. Group selection may favour between-group conflict as well as within-group cooperation.

BACKGROUND: Hallucinations and delusions that complicate Parkinson’s disease could lead to nursing home placement and are linked to increased mortality. Cognitive impairments are typically associated with the presence of hallucinations but there are no data regarding whether such a relationship exists with delusions. OBJECTIVE: We hypothesized that hallucinations would be associated with executive and visuospatial disturbance. An exploratory examination of cognitive correlates of delusions was also completed to address the question of whether they differ from hallucinations. METHODS: 144 PD subjects (...) completed a neuropsychological battery to assess cognition and the SAPS to examine psychosis. Correlational analyses assessed associations between hallucinations and delusions with cognitive domains. RESULTS: 48 subjects reported psychotic symptoms: 25 experienced hallucinations without delusions, 23 had symptoms dominated by delusions. Severity and/or number of hallucination subtypes were significantly correlated with lower scores in language, memory, attention, executive functioning, and visuospatial ability. Correlations with delusions were non-significant. Tests of differences in the size of the correlations between groups revealed a significant relationship between language and visuospatial performance with hallucinations. CONCLUSIONS: Cognitive correlates of hallucinations and delusions appear to be different in PD, suggesting distinct pathogenic mechanisms and possibly anatomical substrates. Hence, delusions may not share the same associations with dementia as hallucinations. Since this is a new finding, further studies will be needed to confirm our results. (shrink)

Shaping off-job life is becoming increasingly important for workers to increase and maintain their optimal functioning. Proactively shaping the job domain has been extensively studied, but crafting in the off-job domain has received markedly less research attention. Based on the Integrative Needs Model of Crafting, needs-based off-job crafting is defined as workers’ proactive and self-initiated changes in their off-job lives, which target psychological needs satisfaction. Off-job crafting is posited as a possible means for workers to fulfill their needs and enhance (...) well-being and performance over time. We developed a new scale to measure off-job crafting and examined its relationships to optimal functioning in different work contexts in different regions around the world. Furthermore, we examined the criterion, convergent, incremental, discriminant, and structural validity evidence of the Needs-based Off-job Crafting Scale using multiple methods. The results showed that off-job crafting was related to optimal functioning over time, especially in the off-job domain but also in the job domain. Moreover, the novel off-job crafting scale had good convergent and discriminant validity, internal consistency, and test–retest reliability. To conclude, our series of studies in various countries show that off-job crafting can enhance optimal functioning in different life domains and support people in performing their duties sustainably. Therefore, shaping off-job life may be beneficial in an intensified and continually changing and challenging working life. (shrink)

To many who develop and use free software, the GNU General Public License represents an embodiment of the meaning of free software. In this paper we examine the definition and meaning of free software in the context of three events surrounding the GNU General Public License. We use a case involving the GPU software project to establish the importance of Freedom 0 in the meaning of free software. We analyze version 3 of the GNU General Public License and conclude that (...) although a credible case can be made that the added restrictions are consistent with the definition of free software, the case requires subtle arguments. Strong arguments against the added restrictions are less subtle, and may therefore be more convincing to many users and developers. We also analyze the Affero General Public License and conclude that it is inconsistent with the definition of free software. (shrink)

Background Genuine uncertainty on superiority of one intervention over the other is called equipoise. Physician-investigators in randomized controlled trials need equipoise at least in studies with more than minimal risks. Ideally, this equipoise is also present in patient-participants. In pediatrics, data on equipoise are lacking. We hypothesize that 1) lack of equipoise at enrolment among parents may reduce recruitment; 2) lack of equipoise during participation may reduce retention in patients assigned to a less favoured treatment-strategy. Methods We compared preferences of (...) parents/patients at enrolment, documented by a questionnaire, with preferences developed during follow-up by an interview-study to investigate equipoise of child-participants and parents in the BeSt-for-Kids-study. This trial in new-onset Juvenile Idiopathic Arthritis-patients consists of three strategies. One strategy comprises initial treatment with a biological disease-modifying-antirheumatic-drug, currently not standard-of-care. Semi-structured interviews were conducted with 23 parents and 7 patients, median 11 months after enrolment. Results Initially most parents and children were not in equipoise. Parents/patients who refused participation, regularly declined due to specific preferences. Many participating families preferred the biological-first-strategy. They participated to have a chance for this initial treatment, and would even consider stopping trial-participation when not randomized for it. Their conviction of superiority of the biological-first strategy was based on knowledge from internet and close relations. According to four parents, the physician-investigator preferred the biological-first-strategy, but the majority stated that she had no preferred strategy. In phase 2, preferences tended to change to the treatment actually received. Conclusions Lack of equipoise during enrolment did not reduce study recruitment, mainly due to the fact that preferred treatment was only available within the study. Still, when developing a trial it is important to evaluate whether the physicians’ research question is in line with preferences of the patient-group. By exploring so-called ‘informed patient-group’-equipoise, successful recruitment may be enhanced and bias avoided. In our study, lack of equipoise during trial-participation did not reduce retention in those assigned to a less favoured option. We observed a change for preference towards treatment actually received, possibly explained by comparable outcomes in all three arms. (shrink)

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)
