Aims and background: Little is known about how participants perceive prevention trials, particularly trials designed to prevent mental illness. This study examined participants’ motives for participating in a trial and their views of randomisation and the ability to withdraw from a randomised controlled trial (RCT) for prevention of depression. Methods: Participants were older adults reporting elevated depression symptoms (N = 900) living in urban and regional locations in Australia who had consented to participate in an RCT of interventions to prevent (...) depression. Participants rated their agreement with various statements describing motivations for enrolment in the trial and opinions regarding randomisation and withdrawal. Results: The majority of participants expressed a triad of altruistic motivation for participation, relative lack of concern about randomisation and commitment to the trial. Certain subgroups of participants, such as women and those with higher depression scores, reported higher levels of concern about specific issues. Conclusions: The findings suggest that participants enrolled in prevention trials for mental illness are likely to hold positive attitudes (eg, high commitment, low expectation of personal gain) towards research trials. The identification of relationships between key person factors and trial-related attitudes enabled profiling of participant groups, which can inform recruitment strategies and interactions of participants and research projects in future prevention trials.

The essays in this volume constitute the proceedings of a conference on the work of Ddonald MacKinnon, this century's most influential British theologian. MacKinnon's work ranges from Aristotelean metaphysics to trinitarian reflection to Marxism. Surin's contributors start with MacKinnon's writings and move on to discuss such topics as his relation to Barth's theology, the controversy betwen realism and idealism, Trinity and ontology, incarnation and kenosis, the problem of evil, and MacKinnon's ethical reflections.

While ancient in origin, the principle, "Do No Harm," continues to occupy a prominent place in many present-day medical ethics codes. Of all the versions of the principle two distinct varieties can be distinguished. These parallel two ethical traditions. This paper develops the contrast between the two versions, relates them to the two ongoing ethical traditions, and then uses insights from contemporary ethical theory to demonstrate the significance of one of the versions. Finally it suggests some contemporary applications for a (...) medical ethic and medical education. Keywords: Hippocratic Oath, harm, intention, agency CiteULike Connotea Del.icio.us What's this?

IntroductionCardiology is characterized by its state-of-the-art biomedical technology and the predominance of Evidence-Based Medicine. This predominance makes it difficult for healthcare professionals to deal with the ethical dilemmas that emerge in this subspecialty. This paper is a first endeavor to empirically investigate the axiological foundations of the healthcare professionals in a cardiology hospital. Our pilot study selected, as the target population, cardiology personnel not only because of their difficult ethical deliberations but also because of the stringent conditions in which they (...) have to make them. Therefore, there is an urgent need to reconsider clinical ethics and Value-Based Medicine. This study proposes a qualitative analysis of the values and the virtues of healthcare professionals in a cardiology hospital in order to establish how the former impact upon the medical and ethical decisions made by the latter.ResultsWe point out the need for strengthening the roles of healthcare personnel as educators and guidance counselors in order to meet the ends of medicine, as well as the need for an ethical discernment that is compatible with our results, namely, that the ethical values developed by healthcare professionals stem from their life history as well as their professional education.ConclusionWe establish the kind of actions, communication skills and empathy that are required to build a stronger patient-healthcare professional relationship, which at the same time improves prognosis, treatment efficiency and therapeutic adhesion.

There are two opposing traditions in contemporary quantum field theory (QFT). Mainstream Lagrangian QFT led to and supports the standard model of particle interactions. Algebraic QFT seeks to provide a rigorous consistent mathematical foundation for field theory, but cannot accommodate the local gauge interactions of the standard model. Interested philosophers face a choice. They can accept algebraic QFT on the grounds of mathematical consistency and general accord with the semantic conception of theory interpretation. This suggests a rejection of particle ontology. (...) Or they can accept the standard model on the grounds of its established success. This alternative, which I defend, suggests revising philosophical accounts of scientific theory and finding some way of accommodating particles. (shrink)
Jean Hamburger (1909--1992) is considered the founder of the concept of medical intensive care (reanimation medicale) and the first to propose the name Nephrology for the branch of medicine dealing with kidney diseases. One of the first kidney grafts in the world (with short-term success), in 1953, and the first dialysis session in France, in 1955, were performed under his guidance. His achievements as a writer were at least comparable: Hamburger was awarded several important literary prizes, including prix Femina, prix (...) Balzac and the Cino del Duca prize (1979), awarded, among others, to Jorge Luis Borges and Konrad Lorenz.Here we would like to offer a selected reading of a "golden" book, "Conseils aux etudiants en medicine de mon service" ("Advice to the Medical Students in my Service"), the first book dedicated to patient-physician relationship in Nephrology, written when dialysis and transplantation were becoming clinical options (1963). The themes include: the central role of the patient, who should be known by name, profession, life style, and not by disease; the importance of the setting of the care; the need for truth-telling and for leaving hope; the role of research not only in the progression of science, but also in the daily clinical practice.

It is assumed that the motion of a particle in spacetime does not depend on the motion relative to it of any observer or of any frame of reference. Thus if the particle has an internal vibration of the type hypothesized by de Broglie, the phase of that vibration at any point in spacetime must appear to be the same to all observers, i.e., the same in all frames of reference. Each observer or reference frame will have its own de (...) Broglie wave for the particle. The phase of the particle's vibration must, by definition, be the same as that of all possible de Broglie waves at the point where the particle is. By superimposing all these possible de Broglie waves, a wave packet is formed centered in space on the particle. The formation of such a packet is discussed with the help of spacetime diagrams; the packet does not spread with time. The relevance of this packet to the wave mechanics of Schrödinger is discussed; it is also pointed out that any vibration can lead to such a packet. (shrink)
It was in 1792 that Kant published the first Book of his most important single work on the philosophy of religion— Religion within the Limits of Reason Alone. But it was his very interesting treatment of the biblical material in the second Book that involved the philosopher in his one serious conflict with official authority. Greene and Hudson give a good account of this conflict and its effect on the work as a whole in the introduction to their translation of (...) Religion in the Harper Torchbook Series. (shrink)
It is now some years since Professor D. Daiches Raphael published his interesting book, The Paradox of Tragedy , which represented one of the first serious attempts made by a British philosopher to assess the significance of tragic drama for ethical, and indeed metaphysical theory. Since then we have had a variety of books touching on related topics: for instance, Dr George Steiner's Death of Tragedy and Mr Raymond Williams’ most recent, elusive and interesting essay, Modern Tragedy. To entitle an (...) essay Theology and Tragedy might be thought to invite needless trouble for oneself; to indulge to a dangerous degree the human intellectual obsession of supposing that ‘the meaning of a word is an object’. After all, if one confines one's regard to the Greeks, one has to recognise that between the treatments of their common theme of Electra , Sophocles and Euripides are in fact doing very different things. There is no gainsaying the significance for Euripides of the postponement of the murder of Clytemnestra till after that of Aegisthus, still less of his introduction into the play of the morally upright peasant, who has had the banished Electra in his keeping, and whose simple integrity contrasts both with the corruption of the court and the obsessive preoccupation with a dreadful, supposed duty of brother and sister. The element of propaganda is unmistakable; while in Sophocles’ Electra it is altogether absent, although Dr Victor Ehrenberg in his very interesting monograph on Sophocles and Pericles has argued strongly for an element of subtle political commentary in the treatment of Oedipus in the Oedipus Tyrannus , and of Pocreon in the Antigone. These remarks may serve to show that the title does not express a blind indifference to the multiple complexity of those works which we class together as tragedies. They are inherently complex, and various in emphasis; at best we can discern a family resemblance between them, and, in an essay like this, the author runs the risk not only of selecting examples tailor-made to his thesis, but also of imposing an appearance of similarity of conception where it is at least equally important to stress differences.

The claim that faith is creative of its objects resides primarily in the conviction that the richness of the life of faith demands that it shall be subject only to its own laws. Its very diversity of expression is indication that it should not be fettered or confined by a restrictive model that outlaws the marvellously unexpected quality of its explorations. Yet that metaphor itself suggests caution; for exploration is necessarily of a territory that the explorer does not bring into (...) being by his voyage or journey. His travels have their own richness; thus Shackleton's famous boat journey has its place in the records of human endurance. But travel assumes a ground to be traversed, and the journey of Ernest Shackleton and the men who sailed with him was not conjured out of nothing, but an achievement made necessary as response to a situation that was itself in no sense of the explorer's contriving. Yet of course we are impatient with the suggestion that it was a mere, largely passive reaction to natural emergency, and only marginally regarded as humanly creative. (shrink)
A simple stationary state is set up by combining the two de Broglie waves from two particles traveling in one direction with equal and opposite velocities. By considering the waves forming this state from the point of view of all possible observers moving in the same direction, it is shown that the basic standing wave pattern does not alter, but that the particle will be confined to a small region stationary relative to this pattern. This region is similar in extent (...) to that confining a free particle, the natural internal frequency of the particle being raised. This agrees with previous suggestions that a particle in a stationary state without angular momentum is stationary. (shrink)
In an article contributed to Mind in 1934, the young A. J. Ayer declared war on metaphysics, claiming that his destruction of the metaphysicians' arguments rested on the establishment of the sheerly non-sensical character of their statements. Their errors were syntactical; the combination of symbols in the sentences with which they expressed their propositions violated fundamental principles of significance.
