The minimum-uncertainty states for systems with many degrees of freedom are investigated. The limiting situation, relevant to the electromagnetic field, is discussed and it is pointed out that the states that minimize Δp Δq do not tend to the coherent states. These latter, including the vacuum state, are minimum-uncertainty states for the transverse electric and magnetic fields. In an appendix a direct method to obtain the wave functional for the vacuum is presented.

PurposeTo use the power of knowledge acquisition and machine learning in the development of a collaborative computer classification system based on the features of age-related macular degeneration (AMD).MethodsA vocabulary was acquired from four AMD experts who examined 100 ophthalmoscopic images. The vocabulary was analyzed, hierarchically structured, and incorporated into a collaborative computer classification system called IDOCS. Using this system, three of the experts examined images from a second set of digital images compiled from more than 1000 patients with AMD. (...) Images were annotated, and features were identified and defined. Decision trees, a machine learning method, were trained on the data collected and used to extract patterns. Interrelationships between the data from the different clinicians were investigated.ResultsSix drusen classes in the structured vocabulary were largely sufficient to describe all the identified features. The decision trees classified the data with 76.86% to 88.5% accuracy and distilled patterns in the form of hierarchical trees composed of 5 to 15 nodes. Experts were largely consistent in their characterization of soft, and to a lesser extent, hard drusen, but diverge in definition of other drusen. Size and crystalline morphology were the main determinants of drusen type across all experts.ConclusionsMachine learning is a powerful tool for the characterization of disease phenotypes. The creation of a defined feature set for AMD will facilitate the development of an IDOCS-based classification system. (shrink)

Recent work has clearly established the fundamental place of the siddhis in almost all Indic mokṣa traditions. This paper seeks to excavate a fundamental metaphysical dimension to this phenomenon, by excavating the philosophical logic of these claims from within the contours of Sāṃkhya metaphysics as expressed in the Yoga Sūtras of Patañjali. It will set out to provide a coherent explanation of how these siddhis are not only an inherent ingredient of yogic discourse, but a logical and perhaps inevitable corollary (...) of the parameters of this metaphysics. It will thus take the issue further than a mere recognition of the centrality of the siddhis to yogic practice and discourse by laying out the sequential metaphysics underpinning them, and hence arguing that siddhis are not only fundamental and intrinsic to the Sāṃkhya/Yoga tradition, but an essential by-product of its metaphysical presuppositions.

This article responds to Stanley J. Grenz's Templeton Lecture, “Why Do Theologians Need to Be Scientists?” published in the June 2000 issue of Zygon (Grenz 2000). In the first part I outline my reasons for finding the kind of theological reflections in which Grenz engages worthy of attention by noting my disagreement with the view that a sufficient response to theological issues can be formulated on the basis of an examination of our biological nature. I assert, in that connection, the (...) autonomy of reason as a way of investigating and understanding the world. In the second part I respond directly to Grenz by explaining my disagreement with the postmodern critique of science upon which he relies and his adherence to Christian eschatology as an answer to the conundrums into which, he posits, we are drawn as a result of that critique. I note that I agree with Grenz, however, that the activity of valuing is necessarily a forward‐looking Godlike endeavor that is not derivable from science. In the third part I suggest that we must be open to the investigation of the possible existence of an objective realm of value and that, in any case, rejection of the postmodern critique of science in many cases pro‐vides a sound basis for the disciplined resolution of factual questions that frequently lie at the base of disagreements about values.

This paper reports two cases in Hong Kong involving two native Chinese adolescent cancer patients (APs) who were denied their rights to consent to necessary treatments refused by their parents, resulting in serious harm. We argue that the dynamics of the ‘AP‐physician‐family‐relationship’ and the dominant role Chinese families play in medical decision‐making (MDM) are best understood in terms of the tendency to hierarchy and parental authoritarianism in traditional Confucianism. This ethic has been confirmed and endorsed by various Chinese writers from (...) Mainland China and Hong Kong. Rather than giving an unqualified endorsement to this ethic, based more on cultural sentimentalism than rational moral reasoning, we warn that a strong familism in MDM, which deprives ‘weak’ family members of rights, represents the less desirable elements of this tradition, against which healthcare professionals working in this cultural milieu need to safeguard. Specifically for APs, we suggest that parental authority and family integrity should be re‐interpreted in terms of parental responsibility and the enhancement of children's interests respectively, as done in the West. This implies that when parents refuse to consent to necessary treatment and deny their adolescent children's right to consent, doctors, as the only remaining advocates of the APs' interest, have the duty to inform the state, which can override parental refusal to enable the doctors to fulfill their professional and moral obligations. In so doing the state exercises its ‘parens patriae’ power to defend the defenseless in society and the integrity of the medical profession. (shrink)

We have begun a theory of measurement in which an experimenter and his or her experimental procedure are modeled by algorithms that interact with physical equipment through a simple abstract interface. The theory is based upon using models of physical equipment as oracles to Turing machines. This allows us to investigate the computability and computational complexity of measurement processes. We examine eight different experiments that make measurements and, by introducing the idea of an observable indicator, we identify three distinct forms (...) of measurement process and three types of measurement algorithm. We give axiomatic specifications of three forms of interfaces that enable the three types of experiment to be used as oracles to Turing machines, and lemmas that help certify an experiment satisfies the axiomatic specifications. For experiments that satisfy our axiomatic specifications, we give lower bounds on the computational power of Turing machines in polynomial time using nonuniform complexity classes. These lower bounds break the barrier defined by the Church-Turing Thesis. (shrink)

Earlier, we have studied computations possible by physical systems and by algorithms combined with physical systems. In particular, we have analysed the idea of using an experiment as an oracle to an abstract computational device, such as the Turing machine. The theory of composite machines of this kind can be used to understand (a) a Turing machine receiving extra computational power from a physical process, or (b) an experimenter modelled as a Turing machine performing a test of a known (...) physical theory T.Our earlier work was based upon experiments in Newtonian mechanics. Here we extend the scope of the theory of experimental oracles beyond Newtonian mechanics to electrical theory. First, we specify an experiment that measures resistance using a Wheatstone bridge and start to classify the computational power of this experimental oracle using non-uniform complexity classes. Secondly, we show that modelling an experimenter and experimental procedure algorithmically imposes a limit on our ability to measure resistance by the Wheatstone bridge.The connection between the algorithm and physical test is mediated by a protocol controlling each query, especially the physical time taken by the experimenter. In our studies we find that physical experiments have an exponential time protocol; this we formulate as a general conjecture. Our theory proposes that measurability in Physics is subject to laws which are co-lateral effects of the limits of computability and computational complexity. (shrink)

This essay addresses directions for the Social Issues in Management (SIM) Division from the perspective of “Back to the Future.” The author was chair of the SIM Division in 1983 to 1984 and the 1989 recipient of the SIM Division’s Sumner Marcus Distinguished Service Award. The essay reviews the general history of SIM during the 1960s and 1970s in which the University of California, Berkeley, played a key role in organizing conferences. The author explains his approach as an applied empiricist (...) to research concerning SIM. The essentials are power, legitimacy, responsibility, rationality, and values, and understanding how they impact the ongoing day-to-day interactions within, between, and among business organizations, their leadership, and other sectors of society. SIM is a field of diverse inquiry which has been the recipient of perspectives and persons drawn not only from multiple disciplines, particularly from the social sciences, law, and management, but also from the humanities and sciences. SIM is patently multi- and inter-disciplinary. (shrink)

The term “aesthetics” is misleading when applied in the classical Indian philosophical context. Before the modern period, there is substantially no body of speculation on the pleasurable responses to created objects, as such, or on their formal capacities to induce such responses. What we do have, on the other hand, are: (1) several partly distinct traditions having to do with the elements out of which are constructed such objects – including literary “objects” – according to prevailing canons of symbology and (...) use that have a ritual or religious basis; and (2) an intensely developed set of speculations on the narrower question of the observed power (often judged in emotive terms) of the dramatic work to transform us, its spectators. This second problematic, in time, comes to be seen as paradigmatic for all “art,” including poetry, music, and the plastic arts. The first set of traditions focuses on what we might call the semantics of the work, contrasting it, in the case of the written work, with “ordinary” symbolical and ritual uses of language “how does it mean what it means?”; the second set deals with the restorative or transformative capacity of dramatic and other “fictive” works, vis‐à‐vis those that immediately and practically provide, or presume to provide, a transcendent solution on human problems – most importantly, of course, the essentially religious problem of human suffering caused by the bondage of cyclic existence “how does the work of art also accomplish human ends?”.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:William Wordsworth and the Hermeneutics of IncarnationEdwin SteinWilliam Wordsworth and the Hermeneutics of Incarnation, by David P. Haney; xiii & 269 pp. University Park: Pennsylvania State University Press, 1993, $35.00.To the English Romantic poets, David Haney notes, the world seemed to have died at the hands of Enlightenment rationalism by being made merely a referent of transpicuous representational sign-systems. One of their fundamental projects was to reanimate it, (...) and Wordsworth committed himself to an animating poetics, incarnational in concept. Haney quotes the Wordsworthian incarnational locus classicus, the third “Essay Upon Epitaphs”: “If words be not... an incarnation of the thought but only a clothing for it, then surely will they prove an ill gift;... Language, if it do not uphold, and feed,... is a counter-spirit unremittingly and noiselessly at work to derange, to subvert, to lay waste, to vitiate, and to dissolve” (p. 1). He conjoins Wordsworth’s statement in a note to “The Thorn” that words should seize us “not as symbols of the passion, but as things, active and efficient, which are themselves part of the passion” (p. 24). “Incarnational” is not further defined directly, though we are told that it characterizes a poetic practice, “a philosophically and theologically important concept embedded [in our cultural] heritage,” and a theoretical orientation that acts “against the very idea of a ‘theory’” (p. 4). Haney draws principally from Gadamer, Lévinas, Cavell, Geoffrey Hartman, and Charles Taylor to explore through philosophical argumentation the ways in which Wordsworth incorporated, elaborated, problematized, and even betrayed these aspects of the incarnational process in his work.One of Haney’s concerns is to show how reading through the lens of incarnational poetics helps us see that Wordsworth incorporated historicity rather than suppressing it, as he is often accused of doing these days. Another is to demonstrate that deconstructive analysis, new-historical critique, and the secularized-Protestantism approach of M. H. Abrams are each inadequate to account for the hermenuetics of this poetics, because it resists and finesses the drive to create the transparent representational structures on which these critics focus. In his incarnational mode, his poetic thought aims not at realizing allegorized abstract truth but at presenting kerygmatically what is instantiated by incarnation as event; thought becomes materially existent without being changed into something else. Incarnational poetics thus acts to counter the binary oppositions (presence/absence, body/spirit, divine/human, etc.) on which both Enlightenment and Romantic discourse relied (the latter reversing the values), and defeats the binarism-dependent drive toward pure self-consciousness that always gets entangled in solipsism and semiological webs. Incarnating thought opens it to the historical process in the sense of Gadamer’s wirkungsgeschichtliches Bewusstsein: incarnation is not embodiment or an “ideal effacement of the difference between word and referent, but rather a process of spirit becoming event”; and words thereby become “things and events... which must enter the realm of mortality” (p. 19). [End Page 138]Haney links this confrontation of mortality to both Cavell’s idea of skeptical acknowledgment of the mortal other replacing knowledge and Lévinas’ conception of a preontological “saying” that dialogically makes us responsible for the other but must die into the “said” to be understood. These connections allow him to enlarge brilliantly our understanding of The Prelude, Book 5, and the “Lucy poems.” Here words achieve visionary power not by a symbolic link to transcendence but “by allowing themselves to be interrupted by that which is absolutely other, and therefore ‘infinite’ in Levinas’ sense” (p. 87). Haney extends this and related insights in a chapter on the final books of The Prelude that shows, among other things, how its figural structures for the autobiographical self begin to break down and are replaced by tropological performatives. These lead away from a systematic code of representation but allow recuperation through the “dialogue” with Coleridge, a non-totalizing process of closure that by linking the autobiographical self to the extratextual self opens the poem to a “range of projective sympathies” (Charles Altieri, quoted in Haney, p. 137).Haney also explores how the incarnational hermeneutic works to close the widening gap between epistemology and ethics fostered by the Enlightenment’s commitment...

This article seeks to explain the correspondence between human intelligibility and that of the physical world by synthesizing the contributions of Jean Ladrière. Ladrière shows that the objectification function of formal symbolism in mathematics as an artificial language has operative power acquired through algorithm to represent physical reality. In physical theories, mathematics relates to observations through theoretic and empirical languages mutually interacting in a methodological circle, and nonmathematical anticipatory intention guides mathematical algorithmic exploration. Ladrière reasons that mathematics can make (...) the physical world comprehensible because of the presence of a rational principle in both kinds of intelligibility. (shrink)

International affairs were a main concern for Smith, yet his views on this topic are largely overlooked or misinterpreted. As a result, the academic literature still contains many erroneous presentations of his views, which this chapter seeks to readdress. Perhaps the most prevalent is the idea that Smith should be counted among those liberal thinkers who thought conflict in international affairs could be abolished. Smith held a realistic view on human nature, which entailed that conflict was an inevitable part of (...) life and thus of politics at all levels. The boundaries of the nation were the natural limit to any meaningful emotional attachment to other people. He opposed slavery, saw many problems associated with the European empires and supported the American colonies. International order was needed for the preservation and expansion of individual liberty, which should be fostered through a combination of diplomacy, the balance of power, and war. (shrink)

Part I distinguishes epistemic and choice democracy, attributing the first to the Rawls of A Theory of Justice but arguing that the second is more justifiable. Part II argues that in comparison with the difference principle, three principles — equal participation in choice democracy, no subordinating purpose, and a just wants guarantee — constitute a more rational choice in the original position; and that they better provide all the benefits claimed for the difference principle in its comparison with either average (...) utilitarianism or restricted average utilitarianism (the mixed conception). Part III, despite noting that my conclusions in Part II can all be reached within the Rawlsian framework, suggests that finding the basis of equality in the presuppositions of communicative action rather than in the existence of the two basic moral powers is more conducive to the affirmative conclusions of Parts I and II. It argues that Rawls' conclusions represented in part his not fully carrying out the break with Kant that he identified himself as making. (shrink)

There is a growing interest in the ethics of Health Policy and Systems Research, and especially in areas that have particular ethical salience across HPSR. Hyder et al provide an initial framework to consider this, and call for more conceptual and empirical work. In this paper, we respond by examining the ethical issues that arose for researchers over the course of conducting three HPSR studies in Kenya in which health managers and providers were key participants. All three studies involved qualitative (...) work including observations and individual and group interviews. Many of the ethical dilemmas researchers faced only emerged over the course of the fieldwork, or on completion, and were related to interactions and relationships between individuals operating at different levels or positions in health/research systems. The dilemmas reveal significant ethical challenges for these forms of HPSR, and show that potential ‘solutions’ to dilemmas often lead to new issues and complications. Our experiences support the value of research ethics frameworks, and suggest that these can be enriched by incorporating careful consideration of context embedded social relations into research planning and conduct. Many of these essential relational elements of ethical practice, and of producing quality data, are given stronger emphasis in social science research ethics than in epidemiological, clinical or biomedical research ethics, and are particularly relevant where health systems are understood as social and political constructs. We conclude with practical and research implications. (shrink)

A common quest among theoretical psychologists is the transformation of psychology to accommodate human agency and meaning. Several strong experimental methods are used in cognitive neuroscience but are based almost entirely upon a mechanistic ontology. A step toward rapprochement is proposed using precise and powerful experimental methods that are holistic, individualized, and compatible with an agentive ontology. Such methods must be applicable to all aspects of human experience, the subjective and agentive aspects, as well as the behavioural and the neurophysiological (...) Multivariate methods are capable of expressing and capturing the holistic isomorphism among multiple aspects of human existence and might even help provide insight into the mind-body problem. Results from a cognitive neuroscience study are used to illustrate this approach. 2012 APA, all rights reserved). (shrink)
