Objectives: to assess physicians’ and patients’ views in Saudi Arabia towards involving the patient versus the family in the process of diagnosis disclosure and decision-making, and to compare them with views from the USA and Japan.Design: A self-completion questionnaire was translated to Arabic and validated.Participants: Physicians from different specialties and ranks and patients in a hospital or attending outpatient clinics from 6 different regions in KSA.Results: In the case of a patient with incurable cancer, 67% of doctors and 51% of (...) patients indicated that they would inform the patient in preference to the family of the diagnosis . Assuming the family already knew, 56% of doctors and 49% of patients would tell the patient even if family objected . However, in the case of HIV infection, 59% of physicians and 81% of patients would inform the family about HIV status without the patient’s consent . With regards to withholding ventilatory support, about 50% of doctors and over 60% of patients supported the use of mechanical ventilation in a patient with advanced cancer, regardless of the wishes of the patient or the family. Finally, the majority of doctors and patients were against assisted suicide.Conclusions: Although there was more recognition for a patient’s autonomy amongst physicians, most patients preferred a family centred model of care. Views towards information disclosure were midway between those of the USA and Japan. Distinctively, however, decisions regarding life prolonging therapy and assisted suicide were not influenced to a great extent by wishes of the patient or family, but more likely by religious beliefs.

This slender volume contains a rapid sketch of the development of the notions of conscience and synderesis in medieval thought. Its timeliness is vouched for by the fact that conscience, to which appeal is so often made today, has not been thus far a major theme of modern philosophy. Much of the book's information is quarried from O. Lottin's classic study, Psychologie et morale aux XIIe et XIIIe siècles, whose findings have been restated in terms that are meant to be (...) "psychologically" accessible to the modern mind. The Preface calls attention to the undue neglect of medieval philosophy on the part of twentieth-century thinkers, many of whom still cling to the view that philosophy died with Aristotle and came to life again only with Descartes. It also laments the "party spirit" that once tended to characterize the Neo-Scholastic movement, as well as the one-sided emphasis on Thomas Aquinas within that movement. Potts has accordingly sought to broaden the scope of his inquiry by taking into consideration five widely different authors through whose writings one begins to glimpse the subtlety of the medieval teaching on this important topic: Jerome, who introduced the word "synderesis" into the debate ; Peter Lombard, whose Sentences provided the mandatory point of departure for all subsequent discussions of the subject; Philip the Chancellor, the author of the first medieval treatise on conscience; and, finally, Bonaventure and Thomas Aquinas, two of the writers who contributed most significantly to the further elaboration of the doctrine. By the author's own admission, numerous other theologians, whose names are listed in an appendix, could have been included in the roster or substituted for the ones that are included. The book is divided into two even parts, the first of which presents an analysis of the thought of each of the five theologians mentioned, and the second a selection of representative texts from their works. For the convenience of teachers, a "programme for a medieval-philosophy course on conscience" has been added under Appendix 2. (shrink)

The spin-statistics connection has been proved for nonrelativistic quantum mechanics . The proof is extended here to the relativistic regime using the parametrized Dirac equation. A causality condition is not required.

The parametrized Duffin–Kemmer–Petiau wave equation is formulated for many relativistic particles of spin-0 or spin-1. The first-quantized formulation lacks the fields of creation and annihilation operators which satisfy commutation relations subject to causality conditions, and which are essential to the Quantum Field Theoretic proof of the spin-statistics connection. It is instead proved that the wavefunctions for identical particles must be symmetric by extension of the nonrelativistic argument of Jabs. The causal commutators of Quantum Field Theory restrict entanglement to separations of (...) the order of the Compton wavelength \. The entanglement manifest in the symmetric Duffin–Kemmer–Petiau wavefunctions is unrestricted. (shrink)
