The present work is motivated by recent experiments aimed to measure the propagation velocity of bound electromagnetic field that reveal no retardation in the absence of EM radiation. We show how these findings can be incorporated into the mathematical structure of special relativity theory that allows us to reconsider some selected problems of classical and quantum electrodynamics. In particular, we come to the conclusion that the total four-momentum for a classical system “particles plus fields” ought to be a present state (...) function of moving charges if EM radiation is negligible. In quantum domain, we analyze novel definition of the momentum operator recently suggested in the study of quantum phase effects. It implies that bound EM field energy and momentum are to be present state functions, too. Being in agreement with reported experiments, these conclusions suggest the necessity to carry out more precise experimental verifications for additional and independent determination of propagation properties of bound EM fields. A scheme of a possible experiment on this subject is also proposed. (shrink)

In this paper we pay attention to the inconsistency in the derivation of the symmetric electromagnetic energy–momentum tensor for a system of charged particles from its canonical form, when the homogeneous Maxwell’s equations are applied to the symmetrizing gauge transformation, while the non-homogeneous Maxwell’s equations are used to obtain the motional equation. Applying the appropriate non-homogeneous Maxwell’s equations to both operations, we obtained an additional symmetric term in the tensor, named as “compensating term”. Analyzing the structure of this “compensating term”, (...) we suggested a method of “gauge renormalization”, which allows transforming the divergent terms of classical electrodynamics (infinite self-force, self-energy and self-momentum) to converging integrals. The motional equation obtained for a non-radiating charged particle does not contain its self-force, and the mass parameter includes the sum of mechanical and electromagnetic masses. The motional equation for a radiating particle also contains the sum of mechanical and electromagnetic masses, and does not yield any “runaway solutions”. It has been shown that the energy flux in a free electromagnetic field is guided by the Poynting vector, whereas the energy flux in a bound EM field is described by the generalized Umov’s vector, defined in the paper. The problem of electromagnetic momentum is also examined. (shrink)

Discussion of the concept of evil in Indian philosophy.

The Johns Hopkins-Fogarty African Bioethics Training Program (FABTP) has offered a fully-funded, one-year, non-degree training opportunity in research ethics to health professionals, ethics committee members, scholars, journalists and scientists from countries across sub-Saharan Africa. In the first 9 years of operation, 28 trainees from 13 African countries have trained with FABTP. Any capacity building investment requires periodic critical evaluation of the impact that training dollars produce. In this paper we describe and evaluate FABTP and the efforts of its trainees.Our data (...) show that since 2001, the 28 former FABTP trainees have authored or co-authored 105 new bioethics-related publications; were awarded 33 bioethics-related grants; played key roles on 78 bioethics-related research studies; and participated in 198 bioethics workshops or conferences. Over the past nine years, trainees have collectively taught 48 separate courses related to bioethics and have given 170 presentations on various topics in the field. Many former trainees have pursued and completed doctoral degrees in bioethics; some have become editorial board members for bioethics journals. Female trainees were, on average, less experienced at matriculation and produced fewer post-training outputs than their male counterparts. More comprehensive studies are needed to determine the relationships between age, sex, previous experience and training program outputs. (shrink)

Recent preclinical studies have shown the feasibility of specific variants of nuclear transfer to prevent mitochondrial DNA disorders. Nuclear transfer could be a valuable reproductive option for carriers of mitochondrial mutations. A clinical application of nuclear transfer, however, would entail germ-line modification, more specifically a germ-line modification of the mitochondrial genome. One of the most prominent objections against germ-line modification is the fear that it would become possible to alter ‘essential characteristics’ of a future person, thereby possibly violating the child's (...) right to an open future. As only the nuclear DNA would contain the ingredients for individual characteristics, modification of the mtDNA is often considered less controversial than modification of the nuclear DNA. This paper discusses the tenability of this dichotomy. After having clarified the concept of germ-line modification, it argues that modification of the mtDNA is not substantively different from modification of the nuclear DNA in terms of its effects on the identity of the future person. Subsequently the paper assesses how this conclusion affects the moral evaluation of nuclear transfer to prevent mtDNA disorders. It concludes that the moral acceptability of germ-line modification does not depend on whether it alters the identity of the future child—all germ-line modifications do—but on whether it safeguards the child's right to an open future. If nuclear transfer to prevent mtDNA disorders becomes safe and effective, then dismissing it because it involves germ-line modification is unjustified. (shrink)

It is important to recognize that the problem dealt with by Plato in the central part of the Sophist is one which arises from the use of certain Greek phrases, and has no necessary or direct connexion with metaphysics. We tend to obscure this fact if we use English terms such as ‘Being’, ‘Reality’, ‘Existence’, etc., in discussing the dialogue, and indeed make it almost impossible to understand what Plato is trying to do. It is the way in which die (...) Greek terms ỗν and μή ỗν and other such terms are used by the ‘sophists’ which gives rise to the problem. (shrink)

How did bioethics manage to grow, flourish and ultimately do so well from a very unpromising birth in the 1970s? Many explanations have been advanced. Some ascribe the field9s growth to a puzzling, voluntary abnegation of moral authority by medicine to non-physicians. Some think bioethics survived by selling out to the biomedical establishment—public and private. This transaction involved bestowing moral approbation on all manner of biomedicine9s doings for a seat at a well-stocked funding table. Some see a sort of clever (...) intellectual bamboozlement at work wherein bioethicists pitched a moral elixir of objective expertise that the morally needy but unsophisticated in medicine and the biological sciences were eager to swallow. While each of these reasons has its defenders, I think the main reason that bioethics did well was that it did good. By using the media to move into the public arena, the field engaged the public imagination, provoked dialogue and debate, and contributed to policy changes that benefitted patients and healthcare providers.

The influence of East on West - of Eastern ideas on Western thought - has become an increasingly vexed issue in recent times. Opinion is divided between two main schools: those who believe that Oriental ideas have exercised a considerable influence on Western thought, and those who, for a variety of reasons, believe that such influence has remained negligible.In this Reader A. L. Macfie suggests that the reality lies somewhere between these two extremes, and that the interest taken by Western (...) thinkers in Eastern thought in the modern period has moved from one of passing interest, through serious attention, to some level of assimilation and acceptance.Eastern Influences on Western Philosophy explores the extent of Oriental influence on European thought, primarily in the period of the Enlightenment and the nineteenth-century period of doubt and scepticism that followed it. As such it is the first Reader to bring together in one place a series of specific historical and textual studies of Oriental influence upon European thinkers. Starting with Malebranche and ending with Heidegger, other Western thinkers considered include Leibniz, Voltaire, Hume, Hegel, Schopenhauer, Emerson, Thoreau, Nietzsche, Jung and Buber.To accompany the readings the editor's introduction explores the idea of influence in the context of the chosen readings, and at the same time raises the question of how far Edwards Said's thesis regarding Orientalism actually applies to Western thought.Key Features:* Reflects increasing interest in relationship between Eastern and Western Philosophy* Covers major European figures from the 18th and 19th centuries and the way Eastern thought influenced them* Substantial editorial introduction places readings in context and explores the influence of the East on the West* Previous work by editor praised for its accessibility.
