The National Blood Policy in India relies heavily on voluntary blood donors, as they are usually assumed to be associated with low levels of transfusion-transmitted infections . In India, it is mandatory to test every unit of blood collected for hepatitis B, hepatitis C, HIV/AIDS, syphilis and malaria. Donors come to the blood bank with altruistic intentions. If donors test positive to any of the five infections, their blood is discarded. Although the blood policy advocates disclosure of TTI status, donors (...) are not, in practice, informed about their results. The onus is on the donor to contact the blood bank. Out of approximately 16 000 donations in the past 2 years, 438 tested positive for TTI, including 107 for HIV. Only 20% of the donors contacted the blood bank; none of them were HIV positive. Disclosure by blood banks of TTI status by telephone or mail has resulted in serious consequences for some donors. Health providers face an ethical dilemma, in the absence of proper mechanisms in place for disclosure of test results, regarding notification to donors who may test positive but remain ignorant of their TTI status. Given the high cost of neglecting to notify infected donors, the authors strongly recommend the use of rapid tests before collecting blood, instead of the current practice, which takes 3 h to obtain results, and disclosure of results directly to the donor by a counsellor, to avoid dropouts and to ensure confidentiality.

The contemporary view of the fundamental role of time in physics generally ignores its most obvious characteric, namely its flow. Studies in the foundations of relativistic mechanics during the past decade have shown that the dynamical evolution of a system can be treated in a manifestly covariant way, in terms of the solution of a system of canonical Hamilton type equations, by considering the space-time coordinates and momenta ofevents as its fundamental description. The evolution of the events, as functions of (...) a universal invariant world, or historical, time, traces out the world lines that represent the phenomena (e.g., particles) which are observed in the laboratory. The positions in time of each of the events, i.e., the time of their potential detection, are, in this framework, controlled by this universal parameter τ, the time at which they are generated (and may proceed in the positive or negative sense). We find that the notion of thestate of a system requires generalization; at any given τ, it involves information about the system at timest(τ) ≠ τ. The correlation of what may be measured att(τ) with what is generated at τ is necessarily quite rigid, and is related covariantly to the spacelike correlations found in interference experiments. We find, furthermore, that interaction with Maxwell electromagnetism leads back to a static picture of the world, with no real evolution. As a consequence of this result, and the requirement of gauge invariance for the quantum mechanical evolution equation, we conclude that electromagnetism is described by a pre-Maxwell field, whose τ-integral (or asymptotic behavior as τ → ∞) may be identified with the Maxwell field. We therefore consider the world of events in space time, interacting through τ-dependent pre-Maxwell fields, as far as electrodynamics is concerned, as the objective dynamical reality. Our perception of the world, through laboratory detectors and our eyes, are based onintegration over τ over intervals sufficiently large to obtain an aposteriori description of the phenomena which coincides with the Maxwell theory. Fundamental notions, such as the conservation of charge, rest on this construction. The decomposition of the common notion of time into two essentially different aspects, one associated with an unvarying flow, and the second with direct observation subject to dynamical modification, has profound philosophical consequences, of which we are able to explore here only a few.

This paper examines a model of income and quality of life that controls the love of money, job satisfaction, gender, and marital status and treats employment status (full-time versus part-time), income level, and gender as moderators. For the whole sample, income was not significantly related to quality of life when this path was examined alone. When all variables were controlled, income was negatively related to quality of life. When (1) the love of money was negatively correlated to job satisfaction and (...) (2) job satisfaction was positively related to both income and quality of life, income was negatively related to quality of life for full-time, high-income, and male employees. When these two conditions failed to exist, income was not related to quality of life for part-time, median- or low-income, and female employees. This model provides new insights regarding the impact of the love of money and job satisfaction on the income–quality of life relationship. (shrink)
The gauge compensation fields induced by the differential operators of the Stueckelberg-Schrödinger equation are discussed, as well as the relation between these fields and the standard Maxwell fields; An action is constructed and the second quantization of the fields carried out using a constraint procedure. The properties of the second quantized matter fields are discussed.
Gauge invariance of a manifestly covariant relativistic quantum theory with evolution according to an invariant time τ implies the existence of five gauge compensation fields, which we shall call pre-Maxwell fields. A Lagrangian which generates the equations of motion for the matter field (coinciding with the Schrödinger type quantum evolution equation) as well as equations, on a five-dimensional manifold, for the gauge fields, is written. It is shown that τ integration of the equations for the pre-Maxwell fields results in the (...) usual Maxwell equations with conserved current source. The analog of the O (3, 1) symmetry of the usual Maxwell theory is found to be O (3, 2) or O (4, 1), depending on the space-time Fourier spectrum of the field. We argue that the structure that is relevant to the description of radiation in interaction with matter evolving in a timelike sense is that of O (3, 2). The noncovariant form of the field equations is given; there are two fields of electric type and one (divergenceless) magnetic type field. The Noether currents are studied, and some remarks are made on second quantization. (shrink)
Some of the problems associated with the construction of a manifestly covariant relativistic quantum theory are discussed. A resolution of this problem is given in terms of the off mass shell classical and quantum mechanics of Stueckelberg, Horwitz and Piron. This theory contains many questions of interpretation, reaching deeply into the notions of time, localizability and causality. A proper generalization of the Maxwell theory of electromagnetic interaction, required for the well-posed formulation of dynamical problems of systems with electromagnetic interaction is (...) discussed, and some of the significance of recently found (classical) relativistic chaotic behavior is pointed out. Many results of a technical nature have been achieved in this framework; in this paper, some of these are reviewed, but I shall concentrate on a discussion of the basic ideas and foundations of the theory.

A fundamental problem in the construction of local electromagnetic interactions in the framework of relativistic wave equations of Klein-Gordon or Dirac type is discussed, and shown to be resolved in a relativistic quantum theory of events described by functions in a Hilbert space on the manifold of space-time. The relation, abstracted from the structure of the electromagnetic current, between sequences of events, parametrized by an evolution parameter τ (“historical time”), and the commonly accepted notion of particles is reviewed. As an (...) illustration of these ideas, a perturbative calculation is made for photon emission from a charged two-body system in which the electromagnetic field is quantized in the usual way. The result is in essential agreement with calculations in which the charged particles are treated in the framework of nonrelativistic quantum mechanics, and provides them with a relativistic interpretation. In particular, we obtain a relativistically invariant form of the Bohr radiation condition. (shrink)
Gilbert Ryle in The Concept of Mind pronounced the “official doctrine” regarding the nature of the mind and the body as “hailing chiefly from Descartes.” That doctrine, anathematized by Ryle as “the dogma of the ghost in the machine,” is said to hold that every human being is composed of a body and a mind, that the body is physical whereas the mind is not, and that the mind may continue to exist when the body is destroyed. Ryle’s famous attack (...) on the official doctrine has undoubtedly stimulated Cartesian studies, both in those who wish to understand Descartes better in order to make the defense of the doctrine more effective and in those who wish to attack it, sometimes even with arguments which Ryle himself would have rejected. Occasionally, one reads a reference to “Platonic dualism,” not so much as a clearly defined alternative to Cartesian dualism but rather as an inchoate or loose version of Descartes’ doctrine. A recent exception is Richard Rorty who in the first chapter of his book Philosophy and the Mirror of Nature has insisted on the difference between the Platonic and the Cartesian positions, although it should perhaps be added that his hostility to the former is if anything greater than his hostility to the latter. Without suggesting that there are not obvious similarities in the Platonic and Cartesian versions of dualism, it will perhaps be useful to try to penetrate beneath the slogans in order to get a clearer picture of the arguments which impelled Plato to hold a position the strangeness which was evident even to his contemporaries.

The dynamical equations of relativistic quantum mechanics prescribe the motion of wave packets for sets of events which trace out the world lines of the interacting particles. Electromagnetic theory suggests thatparticle world line densities be constructed from concatenation of event wave packets. These sequences are realized in terms of conserved probability currents. We show that these conserved currents provide a consistent particle and antiparticle interpretation for the asymptotic states in scattering processes. The relation between current conservation and unitarity is used (...) to establish relations between pair production and annihilation amplitudes and scattering. The discrete symmetriesC, T, P are studied and it is shown that no Dirac sea (for fermions where such a construction is possible, or bosons where it is not) is required for consistency of the theory. These currents, furthermore, represent the discrete symmetries in a way consistent with their interpretation as particle currents. (shrink)
In this paper we show that the prime ideal space of an MV-algebra is the disjoint union of prime ideal spaces of suitable local MV-algebras. Some special classes of algebras are defined and their spaces are investigated. The space of minimal prime ideals is studied as well.
Pope John Paul II's opposition to the Iraq War was not that it failed to meet the conditions of Just War Theory. Indeed, we cannot tell from what he publicly said whether he thought it met those conditions or not, for he would have opposed it in any case. His thinking was rather that even just and necessary wars always come, as it were, too late, and are never able to solve the problems that made wars just and necessary. He (...) was not trying therefore to enter into the details of Just War Theory. He wanted to subsume the principles of war into the principles of peace and to do so, not by denying justice, but by transcending it with charity. This article shows how this thinking is to be understood and the many means the Pope devised for putting this thinking into practice. (shrink)
The fundamental axioms of the quantum theory do not explicitly identify the algebraic structure of the linear space for which orthogonal subspaces correspond to the propositions (equivalence classes of physical questions). The projective geometry of the weakly modular orthocomplemented lattice of propositions may be imbedded in a complex Hilbert space; this is the structure which has traditionally been used. This paper reviews some work which has been devoted to generalizing the target space of this imbedding to Hilbert modules of a (...) more general type. In particular, detailed discussion is given of the simplest generalization of the complex Hilbert space, that of the quaternion Hilbert module. (shrink)
Professor Plant has presented a briefer treatment of Hegel’s philosophical development than did H. S. Harris in Towards the Sunlight, and a considerably more historical, epistemological and metaphysical treatment than is presented in Pelcynski’s Hegel; Political Philosophy and not so exhaustive an account of the political and social philosophy as appears in Avineri’s Hegel’s Philosophy of the Modern State. These four books taken together testify to the importance of Hegel on the contemporary philosophic scene. Plant’s volume is perhaps the best (...) in that it pulls together the various philosophical, political, and social strains in brief compass, for he demonstrates quite convincingly, as did Avineri and Harris, that the political and metaphysical writings of Hegel are closely interconnected and that the interpretation of art and religion flow from his considered interpretation of his contemporary cultural situation. Plant, with Marx, Engels, Kierkegaard, Baur, Feuerbach et al. and against Findlay and Bergman, argues that there is a Christian theological residue in Hegel’s system, but surprisingly, the fruit of the system is clarification not mystification. Only with that residue is the system and totality really explicable. An altogether welcome book.—R.L.P. (shrink)
Professor Crites comes to his task with deep personal sympathy for and philosophic commitment to each of the protagonists in his volume. The subject of Crites’ work is not the tension of faith and history with which we are familiar in the works of Strauss, Baur, Feuerbach, Renan, and M. Arnold, but rather the tension of Christianity and culture. Crites chooses for his departure the notion and analogy of "domesticity," the accommodation, or lack thereof, of the gospel and the world. (...) With a fairness that is singularly unique among Hegelian critics of Kierkegaard, Crites argues that the issue between Kierkegaard and Hegel was the problem of the positivity of the Christian religion. For Hegel, the development of the notion of Christianity as the absolute religion solved the problem raised by the problem of positivity and Lessing’s essay "On the Proof of the Power and the Spirit." For Kierkegaard such a solution was a sellout, for it eliminated faith. Crites argues well the logic of both Kierkegaard’s and Hegel’s positions. Though the author has a few judicious things to say about Kierkegaard’s epistemology, his treatment would have profited by a more extended analysis of the epistemology of both Hegel and Kierkegaard, and by some indications regarding the importance and use of the modal categories in his author’s appraisal of both faith and history—R.

This survey of the history of Protestant thought in the nineteenth century is founded upon two major methodological principles. The first is the hard-nosed avoidance of the national history approach. In spite of the continuity in certain nations of specific theological traditions there is another sense in which the varying efforts of Protest theology struggled to answer the same questions. Welch chose to ignore, as far as possible, national boundaries and concentrate on what can usefully be called the "Victorian era" (...) historically or in theological parlance the period "between Schleiermacher and Ritschl." By ignoring national boundaries and linguistic divisions Welch is able to discuss Feuerbach, Emerson, Comte, Mill, Carlyle, and the Arnolds in one chapter. This brings us to the second methodological point: Welch has included a number of figures in his survey who are not academic theologians but rather literary men or philosophers, as Coleridge, Emerson, Hegel, the Arnolds, Comte, Mill, Carlyle, etc. What might be a surprise here is the inclusion of the literary types. This work, when complete will compare favorably on the period covered with E. Hirsch’s Geschichte der Neuern [[sic]] Evangelischen Theologie, in Zusammenhang mit der Algemeinen [[sic]] Bewegnungen [[sic]] des Europaischen [[sic]] Denkens. The present book can be supplemented by the author’s God and Incarnation in Midnineteenth [[sic]] Century German Theology in "A Library of Protestant Thought" which contains vital readings of Thomasius, Dorner, and Biedermann. Three points, briefly, in criticism. The treatment of Hegel’s notion of spirit in relation to religion is not quite right. Also, the treatment of Kierkegaard as a right-wing Hegelian is quite surprising after Löwith’s placing of him in the left-wing group in From Hegel to Nietzsche, pp. 110-115. Then too, one questions whether Kierkegaard should be dubbed a "theological conservative".—R. L. P. (shrink)
The volume contains new translations of the introduction and preface to the second edition of The Essence of Christianity and Principles of the Philosophy of the Future. This comprises about one-half of the book. The remainder is Hanfi’s fifty-page introduction and translations of "Towards a Critique of Hegel’s Philosophy," "The Beginning of Philosophy," "The Necessity of a Reform of Philosophy," "Preliminary Theses on the Reform of Philosophy," and "Fragments Concerning the Characteristics of My Philosophical Development." The translations are quite readable. (...) Hanfi’s introduction refers to the relation of Feuerbach to Marx in the first and third sections while the second is given over to a survey of Feuerbach’s development and thought. Another aspect, and one of the most suggestive, is at the end of the first section where Hanfi attempts to show how Feuerbach’s anthropology relates to Heidegger’s Daseinsanalytik. One of the most interesting sections of Feuerbach’s text is "On the beginning of Philosophy," for Kierkegaard, in the context of fathering another philosophy of a very different kind, came upon some of the same criticisms of Hegel’s philosophy. This translation, along with those of Essence of Christianity, and the more recent The Essence of Religion, The Essence of Faith According to Luther, and the book by Kamenka, The Philosophy of Ludwig Feuerbach, bespeak a renewed interest in the essential Feuerbach.—R.L.P.

This book continues the Muirhead Library of Philosophy series. It is a sequel to Trethowan’s own Absolute Value, to which frequent reference is made by the author. Together with that work, it comprises the lectures the author delivered in the Department of Religion of Brown University in 1969. It is chiefly a work of theological reflection: Trethowan is seeking new conceptual models for the Christian experience of God. In this vein, he devotes the bulk of the book to explorations of (...) the nature of faith and of the At-onement effected in the experience of God by the Christian mystics. An interesting treatment of the mystical experience of the Absolute concludes the book. This is not to suggest that Trethowan’s work will not be of interest to a general philosophical audience as well. The author begins his investigations with a discussion of contemporary positions which are opposed to metaphysical and theistic claims; within this context, Trethowan’s suggests some useful criticisms of Flew’s position. Searching for an experience of the Absolute that can serve to ground theistic claims, Trethowan examines the formulations of Coreth and Marcel; in the author’s estimate each yields an important emphasis, although some criticism must be directed to their respective accounts. The author’s own solution surfaces in the course of his treatment of faith. Its inspiration is largely Blondel’s "logic of action" : man’s experience of his own range of action leads him to an "option" in favor of the Absolute, an option which includes assent to the Christian experience of the Absolute. Trethowan also indicates a theory of signs, in which signs mediate but also are dynamically directed toward an experienced Absolute. The author’s treatment of Blondel has the advantage of providing the reader with lengthy citations from Blondel in translation.—W. L. P. (shrink)
The requirement of gauge invariance for the Schwinger-DeWitt equations, interpreted as a manifestly covariant quantum theory for the evolution of a system in spacetime, implies the existence of a five-dimensional pre-Maxwell field on the manifold of spacetime and “proper time” τ. The Maxwell theory is contained in this theory; integration of the field equations over τ restores the Maxwell equations with the usual interpretation of the sources. Following Schwinger's techniques, we study the Green's functions for the five-dimensional hyperbolic field equations (...) for both signatures ± [corresponding to O(4, 1) or O(3, 2) symmetry of the field equations] of the proper time derivative. The classification of the Green's functions follows that of the four-dimensional theory for “massive” fields, for which the “mass” squared may be positive or negative, respectively. The Green's functions for the five-dimensional field are then given by the Fourier transform over the “mass” parameter. We derive the Green's functions corresponding to the principal part ΔP and the homogeneous function Δ 1 ; all of the Green's functions can be expressed in terms of these, as for the usual field equations with definite mass. In the O(3, 2) case, the principal part function has support for x2⩾τ2, corresponding to spacelike propagation, as well as along the light cone x2=0 (for τ=0). There can be no transmission ofinformation in spacelike directions, with this propagator, since the Maxwell field, obtained by integration over τ, does not contain this component of the support. Measurements are characterized by such an integration. The spacelike field therefore can dynamically establish spacelike correlations. (shrink)
Purpose Although surrogate decision-making is prevalent in intensive care units and concerns with decision quality are well documented, little is known about how clinicians help family members understand the surrogate role. We investigated whether and how clinicians provide normative guidance to families regarding how to function as a surrogate. Subjects and methods We audiorecorded and transcribed 73 ICU family conferences in which clinicians anticipated discussing goals of care for incapacitated patients at high risk of death. We developed and applied a (...) coding framework to identify normative statements by clinicians regarding what considerations should guide surrogates’ decisions, including whether clinicians explained one or more of Buchanan and Brock’s three standard principles of SDM to family members. Results Clinicians made at least one statement about how to perform the surrogate role in 24 conferences ). We observed three general types of normative guidance provided to surrogates, with some conferences containing more than one type of guidance: counselling about one or more standard principles of SDM ; counselling surrogates to make decisions centred on the patient as a person, without specifying how to accomplish that ; and counselling surrogates to make decisions based on the family’s values. Conclusions Clinicians did not provide normative guidance about the surrogate role in two-thirds of family conferences for incapacitated patients at high risk for death. When they did, clinicians’ guidance was often incomplete and sometimes conflicted with standard principles of SDM. Future work is needed to understand whether providing explicit guidance on how to perform the surrogate role improves decision-making or mitigates surrogates’ psychological distress. (shrink)
These two volumes complete the topical selections from Kierkegaard’s papers. Volume 3 covers L-R. Volume 4 covers S-Z. The entries are arranged chronologically within the topic. The forthcoming Volumes 5 and 6 will carry the autobiographical material. Volume 7 will contain a complete set of indexes and cross references. This is quite an expansion of the five volumes projected in the Hongs’ preface to Volume 1. English students will gain a full volume of selections and a much expanded cross reference (...) and index.
