We argue that the geometry of spacetime is a convention that can be freely chosen by the scientist; no experiment can ever determine this geometry of spacetime, only the behavior of matter in space and time. General relativity is then rewritten in terms of an arbitrary conventional geometry of spacetime in which particle trajectories are determined by forces in that geometry, and the forces determined by fields produced by sources in that geometry. As an example, we consider radial trajectories in (...) the field of a single particle expressed in the spacetime of special relativity. (shrink)

The ever-growing acceptance and use of assisted human reproduction techniques has caused demand for “donated” sperm and eggs to outstrip supply. Medical professionals and others argue that monetary reward is the only way to recruit sufficient numbers of “donors”. Is this a clash between pragmatics and policy/ethics? Where monetary payments are the norm, alternative recruitment strategies used successfully elsewhere may not have been considered, nor the negative consequences of commercialism on all participants thought through. Considerations leading some countries to ban (...) the buying and selling of sperm, eggs and embryos are outlined and a case made that the collective welfare of all involved parties be the primary consideration in this, at times heated, debate.

Reichenbach wrote this book just after taking the first course Einstein ever taught on the theory of relativity. His important and influential work The Philosophy of Space and Time was written several years later and relied in part on the axiomatization of the special and general theories of relativity already worked out in this book. For special relativity Reichenbach divides his axioms into two sets, the light axioms which relate light signals to the topology and metric of time and space, (...) and the matter axioms which do the same for rigid rods and clocks. Thus the axioms focus on the conventions uniting theory and observation and give more insight into the physical foundations of the theory than do most axiomatizations. Reichenbach's approach has been criticized by Weyl and others, but at least some of the criticism seems to rest on a misunderstanding of what Reichenbach was attempting to do. Now that this early work has been translated into English, there is hope that it will be more widely read. There is no doubt that students of the theory or of recent philosophical discussion of space and time will profit from a careful reading of this book.--R. H. K. (shrink)

Those who read this book may be more impressed with its author than the man about whom he is writing. Loren Eiseley is an anthropologist, naturalist and humanist, but more than this he is a man who has a talent for poetic expression. His ardent admiration of Bacon, the heralder [[sic]] of the scientific age, permeates the work and motivates him to speak of the philosopher as "the greatest Elizabethan voyager of all time—a man who sounded the cavernous surges of (...) the darkest sea against which men will ever contend: the sea of time itself." For Eiseley, Bacon is the forerunner of modern times with its awareness of the viability of science in the affairs of man. Bacon recognized the import of the history of philosophy and science and was consumed with the idea that nature is an infinite plenum of hidden potentiality beckoning man to unfold its mysteries and truths. He thought a new frontier could be forged grounded on a "new organ," an inductive method born of the marriage between reason and imagination. He was anxious to achieve triumph of the experimental method and harshly criticized Aristotle’s inductive method. One familiar with Aristotle, however, is cognizant of the fact that he was not, as Bacon contended, caught up with "simple enumeration" but maintained that scientific knowledge as a knowledge of the four causes did not preclude any serious attempts to discover real causal connections.

Aim: To examine how physicians’ life stances affect their attitudes to end-of-life decisions and their actual end-of-life decision-making.Methods: Practising physicians from various specialties involved in the care of dying patients in Belgium, Denmark, The Netherlands, Sweden, Switzerland and Australia received structured questionnaires on end-of-life care, which included questions about their life stance. Response rates ranged from 53% in Australia to 68% in Denmark. General attitudes, intended behaviour with respect to two hypothetical patients, and actual behaviour were compared between all large (...) life-stance groups in each country.Results: Only small differences in life stance were found in all countries in general attitudes and intended and actual behaviour with regard to various end-of-life decisions. However, with regard to the administration of drugs explicitly intended to hasten the patient’s death , physicians with specific religious affiliations had significantly less accepting attitudes, and less willingness to perform it, than non-religious physicians. They had also actually performed PAD less often. However, in most countries, both Catholics and Protestants reported ever having made such a decision.Discussion: The results suggest that religious teachings influence to some extent end-of-life decision-making, but are certainly not blankly accepted by physicians, especially when dealing with real patients and circumstances. Physicians seem to embrace religious belief in a non-imperative way, allowing adaptation to particular situations. (shrink)

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

In the midst of greed, corruption, the economic crash and the general disillusionment of business, current conceptions of leadership, organizational values, and authenticity are being questioned. In this article, we fill a prior research gap by directly exploring the intersection of these three concepts. We begin by delving into the relationship between individual values and organizational values. This analysis reveals that the “value fit” approach to creating authenticity is limited, and also indicates that a deeper exploration of the nature of (...) values and the role of leadership is necessary. More specifically, we propose that organizational values should be viewed as an opportunity for ongoing conversations about who we are and how we connect. Through this type of dialogue which we define as “value through conversation”, we can create what we call poetic organizations. A typology of four interconnected values each of which forms a foundation for the critical questioning and inquiry that might be found in poetic organizations is developed. We suggest that this conceptualization offers a new and dynamic approach for thinking about the relationships between leadership, values, and authenticity and has important implications for both research and practice.

In the current literature, discussions of cognitive penetrability focus largely either on interpreting empirical evidence in ways that is relevant to the question of modularity :343–391, 1999; Wu Philos Stud 165:647–669, 2012; Macpherson Philos Phenomenol Res, 84:24–62, 2012) or in offering epistemological considerations regarding which properties are represented in perception :519–540, 2009, Noûs 46:201–222, 2011; Prinz Perceptual experience, Oxford University Press, Oxford, pp 434–460, 2006). In contrast to these debates, in this paper, I explore conceptual issues regarding how we ought (...) to understand the “cognitive” side of cognitive penetrability. I argue that it is only on its most narrow construal that a full-fledged defense of cognitive impenetrability has been forwarded. Specifically, I argue that the defenders of modularity have tacitly identified cognitive states with propositional states, and have thus only defended the idea that early perceptual systems are immune to the impacts of propositional knowledge. My aim then is to raise doubts about the identification of cognitive states with propositional ones. In particular, by focusing on skill, I will broaden the conceptual space for a greater number of states to have the potential to impact perceptual processing in a way that would constitute a genuine instance of cognitive penetrability.

Klein (philosophy, U. of Northern Florida-Jacksonville) offers an analysis of modern-day feminism and a personal memoir of coming of age and coming to terms with feminism as it relates to university politics and teaching. She presents a critique of contemporary feminism, discussing feminist and nonfeminist philosophy, feminist nonphilosophy, and feminist epistemology and pedagogy. She exposes the dogmas and fallacies of feminism, and argues that feminism is oppressive to women. Annotation copyright by Book News, Inc., Portland, OR.

There has been much discussion concerning the consequences of 'going natural', i.e., of replacing a priori epistemology with empirical psychology. Traditionalists claim that a naturalized epistemology is not viable—to eliminate the normative from an account of knowledge is to cease to do epistemology at all. Naturalists claim that a naturalized account is the only viable one—assuming, in step with the urgings of Quine, that there are no standards independent of (and external to) science, science itself must act as the sole (...) epistemic norm. In the wake of the above debate some epistemologists have attempted to argue in favor of, and develop, a middle-ground position— normative naturalism . Such a position is intended to be consistent with the naturalist's intuition that the traditional search for a 'first philosophy'is misguided and consistent with the traditionalist's intuition that a complete elimination of the normative would leave epistemology impotent. In this paper I will examine one argument in favor of a normative naturalism . / will show that such a proposal is inherently problematic and argue that naturalism and normativity are mutually exclusive concepts. Therefore, I suggest that, even in the 'age of cognitive science', epistemologists continue to do traditional epistemology by attempting to develop, a priori , the general criteria for determining the justificatory status of our (scientific) beliefs.

- How can anthropology improve our understanding of the interrelationship between nature and culture? - What can anthropology contribute to practical debates which depend on particular definitions of nature, such as that concerning sustainable development? Humankind has evolved over several million years by living in and utilizing 'nature' and by assimilating it into 'culture'. Indeed, the technological and cultural advancement of the species has been widely acknowledged to rest upon human domination and control of nature. Yet, by the 1960s, the (...) idea of culture in confrontation with nature was being challenged by science, philosophy and the environmental movement. Anthropology is increasingly concerned with such issues as they become more urgent for humankind as a whole. This important book reviews the current state of the concepts of 'nature' we use, both as scientific devices and ideological constructs, and is organised around three themes: - nature as a cultural construction; - the cultural management of the environment; and - relations between plants, animals and humans.

Humans are experts in cooperating with each other when trying to accomplish tasks they cannot achieve alone. Recent studies of joint action have shown that when performing tasks together people strongly rely on the neurocognitive mechanisms that they also use when performing actions individually, that is, they predict the consequences of their co‐actor’s behavior through internal action simulation. Context‐sensitive action monitoring and action selection processes, however, are relatively underrated but crucial ingredients of joint action. In the present paper, we try (...) to correct the somewhat simplified view on joint action by reviewing recent studies of joint action simulation, monitoring, and selection while emphasizing the intricate interrelationships between these processes. We complement our review by defining the contours of a neurologically plausible computational framework of joint action. (shrink)

The World Medical Association’s revised Declaration of Helsinki endorses the view that all trial participants in every country are entitled to the worldwide best standard of care. In this paper the authors show that this requirement has been rejected by every national and international committee that has examined this issue. They argue that the consensus view now holds that it is ethically permissible, in some circumstances, to provide research participants less than the worldwide best care. Finally, the authors show that (...) there is also consensus regarding the broad conditions under which this is acceptable. (shrink)

The recent financial crisis has prompted questioning of our basic ideas about capitalism and the role of business in society. As scholars are calling for “responsible leadership” to become more of the norm, organizations are being pushed to enact new values, such as “responsibility” and “sustainability,” and pay more attention to the effects of their actions on their stakeholders. The purpose of this study is to open up a line of research in business ethics on the concept of “ authenticity (...) ” as it can be applied in modern organizational life and more specifically to think through some of the foundational questions about the logic of values. We shall argue that the idea of simply “acting on one’s values” or “being true to oneself” is at best a starting point for thinking about authenticity. We develop the idea of the poetic self as a project of seeking to live authentically. We see being authentic as an ongoing process of conversation that not only starts with perceived values but also involves one’s history, relationships with others, and aspirations. Authenticity entails acting on these values for individuals and organizations and thus also becomes a necessary starting point for ethics. After all, if there is no motivation to justify one’s actions either to oneself or to others, then as Sartre has suggested, morality simply does not come into play. We argue that the idea of responsible leadership can be enriched with this more nuanced idea of the self and authenticity. (shrink)

This paper implements the continuous Hindi Automatic Speech Recognition (ASR) system using the proposed integrated features vector with Recurrent Neural Network (RNN) based Language Modeling (LM). The proposed system also implements the speaker adaptation using Maximum-Likelihood Linear Regression (MLLR) and Constrained Maximum likelihood Linear Regression (C-MLLR). This system is discriminatively trained by Maximum Mutual Information (MMI) and Minimum Phone Error (MPE) techniques with 256 Gaussian mixture per Hidden Markov Model(HMM) state. The training of the baseline system has been done using (...) a phonetically rich Hindi dataset. The results show that discriminative training enhances the baseline system performance by up to 3%. Further improvement of ~7% has been recorded by applying RNN LM. The proposed Hindi ASR system shows significant performance improvement over other current state-of-the-art techniques. (shrink)

This paper introduces the medical factual matrix as a new and potentially valuable tool in medical ethical analysis. Using this tool it demonstrates the idea that a defined medical intervention can only be meaningfully declared futile in relation to a defined goal of treatment. It argues that a declaration of futility made solely in relation to a defined medical intervention is inchoate. It recasts the definition of goal futility as an intervention that cannot alter the probability of the existence of (...) the important outcome states that might flow from a defined intervention. The idea of value futility and the extent of physician obligations in futile situations are also addressed. It also examines the source of substantive conflicts which commonly arise within the doctor-patient relationship and the ensuing power relations that operate between doctor and patient when questions of futility arise.

In this paper, I examine how the idea of self-rule is dramatised and articulated in the Protagoras and the Gorgias with respect to the apparently different treatments of hedonism. Looking at the former dialogue, I describe how the hedonist premise develops from a dramatic image of disorder, specifically the absence of self-rule. I then consider whether the evidence from that dialogue has any bearing on the Gorgias’ discussion of hedonism. I conclude that the Socratic rejection of hedonism in that text (...) is about the Calliclean abandonment of any concern for self-rule, an abandonment that actually masquerades as a commitment to self-rule. This analysis is used to present a more general account of what Socrates considers to be the capacities required for good citizenship. (shrink)

The essay begins by the author's recollections of his younger days when people were seldom worried about moral decline in society. Today, however, it has become a real concern. Literature, philosophy, spiritual works are all essentially a celebration of human values. The paper examines the issue of scale of graded values as against that of absolutist universal values. A scrutiny of English literature reveals that some key literary figures in eighteenth-nineteenth century England drew attention to the decline of human values (...) accompanying increasing industrialization. The author discusses his own views on the management and role of human values in it, as also on human values and man's divine nature. He discusses the leader's role and an action programme for human values. The universality of Vedantic monism, and its triple idealism, is suggested as a basis for the regeneration of human values.

Contemporary appeals for a deepening of civic friendship in liberal democracies often draw on Aristotle. This paper warns against a certain kind of attempt to use Aristotle in our own theorising, namely accounts of civic friendship that characterise it as similar in some way to Aristotelian virtue friendship. The most prominent of these attempts have focused on disinterested mutual regard as a basic ingredient in all Aristotelian forms of friendship. The argument against this is that it inadequately accounts for the (...) idea of a virtue friend as another self, which we find in Aristotle’s thought. When we attend closely to that, we see that civic friendship is different in a fundamental way from virtue friendship because virtue friends are keenly committed to the moral improvement of one another. It is argued that Aristotle does not see civic friendship in the same way. However, if this argument about the differences between the forms of friendship cannot be accepted, the paper argues that we should not draw on Aristotle for an understanding of civic friendship because any similarity it might have to virtue friendship would license illiberal interventions in the lives of citizens in service of some idea of moral improvement. A seeming connection between Aristotelian civic friendship and thick conceptions of citizenship is replaced with a connection between it and thinner conceptions. (shrink)
