A quantum theory of the photon is developed in a natural manner. Newton-Wigner and Wightman demonstrated that the photon could not be strictly localized according to natural criteria. These investigations involved the identification of an elementary system with a uirrep of the Poincare group. We identify a particle with the localized measurement of the states satisfying the uirrep. In the case of zero mass and unit spin, the photon is identified with those components of the state that can be localized. (...) A c-number four-vector potential and Lorentz condition are derived from the relativistic wave equation. The Wightman localization is demonstrated for the three independent space components of the vector potential, and the photon is identified with these components. A position operator and probability density follow immediately from the localization. A consequence of the subjective definition of a photon is that the transformations of the vector potential are unitary, and hence the unitary scalar product can be obtained for the four-vector potential. A Hilbert space is defined for the three space components of the vector potential. A position operator and probability density are derived from the scalar product, which compare directly with those obtained from the localization and the non-relativistic theory. As the longitudinal and scalar polarizations do not contribute to the measured transition probability, they are considered virtual. Lastly, a conserved four-vector current is derived from the scalar product. The possibility of observing a strict localization of the photon in the laboratory is suggested. (shrink)

This paper centers its analysis around the remarkable work of the transdisciplinary commentary al-Minaḥ al-quddūsiyya, written by the Algerian scholar Aḥmad al-ʿAlawī (d. 1934). Although they are incredibly rare in the Islamic textual tradi­tion, transdisciplinary commentaries are commentaries that are written in a discipline different from that of the base texts upon which they build. In the case of the Minaḥ, al-ʿAlawī wrote his text as an entirely Sufi commentary upon Ibn ʿĀshir’s (d. 1040/1631) al-Murshid al-muʿīn, a didactic poem that (...) is often categorized as a work of Mālikī fiqh. Through an examination of the text of the Minaḥ and the biography of its author, this paper aims to uncover why al-ʿAlawī wrote his commentary and what his ideological assumptions were that allowed him to approach Ibn ʿĀshir’s Murshid in such a novel manner.

Purpose: to characterize ethics course content, structure, resources, pedagogic methods, and opinions among academic administrators and course directors at U.S. medical schools. Method: An online questionnaire addressed to academic deans and ethics course directors identified by medical school websites was emailed to 157 Association of American Medical Colleges member medical schools in two successive waves in early 2022. Descriptive statistics were utilized to summarize responses. Results: Representatives from 61 (39%) schools responded. Thirty-two (52%) respondents were course directors; 26 (43%) were (...) deans of academic affairs, medical education, or curriculum; and 3 with other roles also completed the survey (5%). All 61 schools reported some form of formal ethics education during the first year of medical school, with most (n = 54, 89%) reporting a formal mandatory introductory course during preclinical education. Schools primarily utilized lecture and small-group teaching methods. Knowledge-based examinations, attendance, and participation were most commonly used for assessment. A large majority regarded ethics as equally or more important than other foundational courses, but fewer (n = 37, 60%) provided faculty training for teaching ethics. Conclusions: Despite a response rate of 39 percent, the authors conclude that medical schools include ethics in their curricula in small-group and lecture formats with heterogeneity regarding content taught. Preclinical curricular redesigns must innovate and implement best practices for ensuring sound delivery of ethics content in future curricula. Additional large-scale research is necessary to determine said best practices. (shrink)

Normothermic Regional Perfusion, or NRP, is a method of donated organ reperfusion using cardiopulmonary bypass or a modified extracorporeal membrane oxygenation (ECMO) circuit after circulatory death while leaving organs in the dead donor’s corpse. Despite its potential, several key ethical issues remain unaddressed by this technology.
