As practicing clinicians, physicians are expected to uphold the ethical norms of their profession, including fidelity to patients and respect for patients’ self-determination. At the same time, as individuals, physicians are moral agents in their own right and, like their patients, are informed by and committed to diverse cultural, religious, and philosophical traditions and beliefs. In some circumstances, the expectation that physicians will put patients’ needs and preferences first may be in tension with the need to sustain the sense of (...) moral integrity and continuity that grounds a physician’s personal and professional life. This article examines the implications for patients, physicians, and the medical profession when tensions arise between a physician’s professional commitments and his or her deeply held personal moral beliefs. It offers guidance on when a physician’s professional commitments should outweigh personal beliefs as well as when physicians should have freedom to act according to the dictates of conscience while still protecting patients’ interests.

A model for the trapping of animals with a circular pitfall is formulated. The model's assumptions are: The animals move independently according to the same Brownian motions. The boundary of the pitfall acts as an absorbing or elastic barrier. Initially a fixed number of animals is independently homogeneously distributed over a finite study area, or the initial positions follow a homogeneous planar Poisson process. The model depends on three free parameters: the motility of the animals, their reaction to the pitfall, (...) the initial density.It appears that the catches in disjoint time intervals are multinomially or independently Poisson distributed. The parameters of these distributions are obtained by solving certain partial differential equations. (shrink)

The tradition that Socrates had two wives at once, Xanthippe and Myrto, though an established one among ancient scholars, has met with blank incredulity in modern times. It impugns the character of Socrates, who has been established by Plato's martyrology as the unimpeachable patron saint of Western philosophy. And it appears to cast a slur on Greek marriage—not that the guiding lines of this somewhat ramshackle institution are perfectly known.
