Einstein, in his “Zur Elektrodynamik bewegter Körper”, gave a physical (operational) meaning to “time” of a remote event in describing “motion” by introducing the concept of “synchronous stationary clocks located at different places”. But with regard to “place” in describing motion, he assumed without analysis the concept of a system of co-ordinates.In the present paper, we propose a way of giving physical (operational) meaning to the concepts of “place” and “co-ordinate system”, and show how the observer can define both the (...) place and time of a remote event. Following Einstein, we consider another system “in uniform motion of translation relatively to the former”. Without assuming “the properties of homogeneity which we attribute to space and time”, we show that the definitions of space and time in the two systems are linearly related. We deduce some novel consequences of our approach regarding faster-than-light observers and particles, “one-way” and “two-way” velocities of light, symmetry, the “group property” of inertial reference frames, length contraction and time dilatation, and the “twin paradox”. Finally, we point out a flaw in Einstein’s argument in the “Electrodynamical Part” of his paper and show that the Lorentz force formula and Einstein’s formula for transformation of field quantities are mutually consistent. We show that for faster-than-light bodies, a simple modification of Planck’s formula for mass suffices. (Except for the reference to Planck’s formula, we restrict ourselves to Physics of 1905.).

Geoffrey Rose’s prevention paradox points to a tension between two prima facie plausible moral principles: that we should save the greater number and that weshould save the most at risk. This paper argues that a novel moral theory, ex-ante contractualism, captures our intuitions in many prevention paradox cases, regardless of our interpretation of probability claims. However, it goes on to show that it might be impossible to square ex-ante contractualism with all of our moral intuitions. It concludes that even if (...) ex-ante contractualism cannot furnish an entire ethics of risk, it does identify important considerations for any such theory. (shrink)

P¯an.ini’s grammar includes several types of metarules which determine how its operational rules apply. Among them are “traffic rules” which constrain how rules interact with each other in grammatical derivations. These are typically formulated as designating a rule or class of rules asiddha “not effected” (or asiddhavat “as if not effected”) with respect to another rule or class of rules. For economy, the rules so designated are grouped into several sections, whose headings collectively declare them to be asiddha(vat). The biggest (...) such section, under the famous heading 8.2.1 p ¯urvatr¯asiddham, extends from 8.2.1 through the end of the grammar (8.4.68), and is hence called the Trip¯ad¯ı ‘Three Sections’.

While there is significant consensus that undergraduate medical education should include bioethics training, there is widespread debate about how to teach bioethics to medical students. Educators disagree about course methods and approaches, the topics that should be covered, and the effectiveness and metrics for UME ethics training. One issue that has received scant attention is the timing of bioethics education during medical training. The existing literature suggests that most medical ethics education occurs in the pre-clinical years. Follow-up studies indicate that (...) medical students in their clinical rotations have little recall or ability to apply ethics concepts that were learned in their pre-clinical training. Trainees also report a desire for medical ethics to be taught in the context of practical application, which would suggest that the timing of pre-clinical ethics education is flawed. However, moving bioethics training to the clinical years should not be assumed to be the solution to the problems of recall and theory application. We argue that the effectiveness of timing bioethics education will depend on when medical students witness or experience particular categories of ethical dilemmas during their training. Our overarching hypothesis is that ethics education will be most effective when the bioethics training on a particular topic correlates to experiential exposure to that ethical issue. The purpose of our current study was to describe medical students exposure to particular categories of ethical conflicts, dilemmas, or issues. Our results may help bioethics educators better strategize about the most effective timing of medical ethics training in UME. (shrink)

The practice of prenatal screening for disability is sometimes objected to because of the hurt and offence such practices may cause to people currently living with disabilities. This objection is commonly termed “the expressivist objection”. In response to the objection it is standardly claimed that disabilities are analogous to illnesses. And just as it would be implausible to suppose reduction of the incidence of illnesses such as flu sends a negative message to ill people, so it is not plausible to (...) suppose prevention of disability sends a negative message to disabled people. The expressivist objection hinges, however, upon a view of the relationship between disability and self identity which sees disability as part of the identity of the disabled person, in a way in which illnesses such as flu cannot be. This possibility is generally not considered in critiques of the expressivist objection. In this paper, an “identity claim” to the effect that disabilities can be identity constituting is accepted and the force of the expressivist argument is reconsidered in the light of its acceptance. It is concluded that even when such an identity claim is accepted, the expressivist objection is still not morally compelling. (shrink)

The relationship between place and remembering has been a long-standing matter of phenomenological concern. The role of the 'lived body' in mediating acts of remembering in context is clearly crucial. In this paper we contribute to an 'expanded view of memory' by describing how remembering difficult or problematic events -- 'vital memories' -- draws upon inter-subjective and inter-objective relations. We discuss two conceptual tools that provide an analytic framework -- the concept of 'life space' drawn from Kurt Lewin and the (...) idea of the 'setting specificity' of remembering. From this perspective we can see that the 'lived body' does not constitute a singular unity but rather a 'plurality' of potential bodies that have 'operative solidarity' with the material relations in which they are constituted. Drawing on the work of Eduardo Viveiros de Castro, we argue that 'body memories' need to be analysed from within the embodied material-relational perspective wherein they are afforded. (shrink)

This paper discusses the predicament of Oscar Pistorius. He is a Paralympic gold medallist who wishes to participate in the Olympics in Beijing in 2008. Following a brief introductory section, the paper discusses the arguments that could be, and have been, deployed against his participation in the Olympics, should he make the qualifying time for his chosen event (400m). The next section discusses a more hypothetical argument based upon a specific understanding of the fair opportunity rule. According to this, there (...) may be a case for allowing Pistorius to compete even if he should fail to make the official qualifying time. The final part of the paper reviews the situation at the time of writing and offers some assessment of the strategy of the IAAF in responding to it. It is argued below that the proper focus for assessment of Pistorius's eligibility to compete should not be on whether his blades lead to his having an unfair advantage over his competitors, but instead should focus on whether what he does counts as running.

The present study explores the Bianchi type I universe in the frame work of f theory of gravity by considering strange quark matter attached to string cloud and domain walls in the presence and absence of magnetism. Field equations are solved by choosing a constant curvature method. It is found that obtained cosmological models are relevant to the early era of evolution of the universe. The strange quark matter may be a source of string cloud and domain walls.

In this article we examine ethical aspects of the involvement of children in clinical research, specifically those who are incapable of giving informed consent to participate. The topic is, of course, not a new one in medical ethics but there are some tensions in current guidelines that, in our view, need to be made explicit and which need to be responded to by the relevant official bodies. In particular, we focus on tensions between the World Medical Association Declaration of Helsinki, (...) and the guidance offered by the British Medical Association, the Royal College of Paediatrics and Child Health , and the Council for International Organizations of Medical Sciences. We conclude with a call for these organisations to make their guidance explicit in relation to the World Medical Association Declaration. (shrink)

Published within weeks of Charles Darwin's Origin of Species, Isabelle Duncan's Pre-Adamite Man (1860) is the first full-length treatment of preadamism by an evangelical. Intended as a reconciliation of Genesis and geology, Duncan's work gained immediacy when it was published shortly after the September 1859 revelations that men had walked among the mammoths. Written in the tradition of evangelical 'Christian philosophy', Pre-Adamite Man deploys innovative biblical hermeneutics and recent trends in geology to set out both a biblical preadamite theory, and (...) an unorthodox angelology. Duncan responded to contemporary secular interpretations of geology by pushing evangelical concordist strategies to new frontiers, filling out an acceptance of an ancient earth with new biblically informed catastrophist proposals and extensions of salvation history, while simultaneously retaining a firm commitment to plenary inspiration. The product is a highly readable book that operates both as an accessible treatment of geology and a theological discourse. Running through six printings between 1860 and 1866, the book was reviewed by many of the period's leading journals and created a minor controversy among evangelicals. This study both brings to life this previously neglected episode in scriptural geology, and adds to recent work on Victorian popular science writing. (shrink)

The purpose of this study is to examine the relationship between the corporate social performance of an organization and three variables: the size of the organization, the financial performance of the organization, and the environmental performance of the organization. By empirically testing data from 1987 to 1992, the results of the study show that a firm's corporate social performance is indeed impacted by the size of the firm, the level of profitability of the firm, and the amount of pollution emissions (...) released by the firm.

This paper examines one particular justification for the screening and termination of embryos/fetuses which possess genetic features known to cause disability. The particular case is that put forward in several places by John Harris. He argues that the obligation to prevent needless suffering justifies the prevention of the births of disabled neonates. The paper begins by rehearsing Harris's case. Then, drawing upon claims advanced in a recent paper in the Journal of Medical Ethics, it is subjected to critical scrutiny, focusing (...) on Harris's “suffering claim” .1 It is argued that the suffering claim must be false if understood as an empirical claim. And, even if understood as a conceptual truth, it mistakenly assimilates the concepts of harm and suffering. Finally, again focusing on Harris's recent work in this area, his characterisation of disability as a “harmed condition” is shown not to apply in the case of at least some moderate forms of intellectual disability.

In this paper the coherence of the precautionary principle as a guide to public health policy is considered. Two conditions that any account of the principle must meet are outlined, a condition of practicality and a condition of publicity. The principle is interpreted in terms of a tripartite division of the outcomes of action . Such a division of outcomes can be justified on either “consequentialist” or “deontological” grounds. In the second half of the paper, it is argued that the (...) precautionary principle is not necessarily opposed to risk–cost–benefit analysis, but, rather, should be interpreted as suggesting a lowering of our epistemic standards for assessing evidence that there is a link between some policy and “special bad” outcomes. This suggestion is defended against the claim that it mistakes the nature of statistical testing and against the charge that it is unscientific or antiscientific, and therefore irrational. (shrink)

This “current controversies” contribution describes the recent case of a severely disabled six year old girl who has been subjected to a range of medical interventions at the request of her parents and with the permission of a hospital clinical ethics committee. The interventions prescribed have become known as “the Ashley treatment” and involve the performance of invasive medical procedures (eg, hysterectomy) and oestrogen treatment. A central aim of the treatment is to restrict the growth of the child and thus (...) make it easier for her parents to care for her at home. The paper below discusses the main objections to the treatment. It concludes that the most serious concern raised by the case is that it may set a worrying precedent if the moral principle employed in justification of the treatment is applied again to endorse it in similar circumstances. Finally, it raises the possibility that that same moral principle may even be invoked to justify more radical interventions than those that were actually performed in the Ashley treatment. (shrink)
