Quantum dots (3–4 nm) of Zn1− x Cd x S (both free of Mn2+ and with Mn2+ incorporated) were synthesized through a novel solvothermal-microwave irradiation technique. Detailed structural analysis of the Zn1− x Cd x S and Zn1− x Cd x S:Mn2+ (x = 0, 0.25, 0.5, 0.75 and 1) materials was carried out using powder X-ray diffraction technique. For all the compositions, the crystallite size was controlled to less than 1.5 nm. The optical energy gap for Zn1− x Cd (...) x S was found to vary from 3.878 to 2.519 eV and for Zn1−x Cd x S:Mn2+ it varies from 3.830 to 2.442 eV when x is increased from 0 to 1. Overall, the optical energy gap could be tuned from a minimum of 2.442 eV to a maximum of 3.878 eV. DC conductivity analysis (from 40°C to 150°C) and electrical energy gap analysis for all the compositions were also performed. The dc conductivity for Zn1− x Cd x S solid solutions varies from 0.3840 × 10−10 to 8.7782 × 10−10 mho/m at 150°C and for Zn1− x Cd x S:Mn2+ it varies from 0.5751 × 10−10 to 9.8078 × 10−10 mho /m at 150°C (for x = 0 to x = 1). The method of synthesis and the results observed in this investigation may assist in the fabrication of optical devices when the required operational performance falls under the range observed in the study.

In this important study D. M. Armstrong offers a comprehensive system of analytical metaphysics that synthesises but also develops his thinking over the last twenty years. Armstrong's analysis, which acknowledges the 'logical atomism' of Russell and Wittgenstein, makes facts the fundamental constituents of the world, examining properties, relations, numbers, classes, possibility and necessity, dispositions, causes and laws. All these, it is argued, find their place and can be understood inside a scheme of states of affairs. This is a comprehensive and (...) rigorously this-worldly account of the most general features of reality, argued from a distinctive philosophical perspective, and it will appeal to a wide readership in analytical philosophy.

In The Quantum Self, Danah Zohar argues that the insights of modem physics can illuminate our understanding of everyday life -- our relationships to ourselves, to others, and to the world at large. Guiding us through the strange and fascinating workings of the subatomic realm to create a new model of human consciousness, the author addresses enduring philosophical questions. Does the new physics provide a basis by which our consciousness might continue beyond death? How does the material world (for instance, (...) ugly inner cities) impinge upon our sense of self? Is there a subatomic wellspring from which our creativity, our empathy with others, and our feelings of unity with the inanimate world originate?Most important, Zohar shows how the vitality of the new physics combats the alienation and fragmentation of twentieth-century life, and replaces it with a model of reality in which the universe itself may possess a type of consciousness, of which human consciousness is one expression.

First, The doctrine of naturalism, That reality is spatio-Temporal, Is defended. Second, The doctrine of materialism or physicalism, That this spatio-Temporal reality involves nothing but the entities of physics working according to the principles of physics, Is defended. Third, It is argued that these doctrines do not constitute a "first philosophy." a satisfactory first philosophy should recognize universals, In the form of instantiated properties and relations. Laws of nature are constituted by relations between universals. What universals there are, And what (...) relations hold between them, Must be discovered "a posteriori" by scientific investigation.

Originally published in 1936, this book presents the ancient Greek text of the paraphrases and quotations of Zeno's philosophical arguments, together with a facing-page English translation and editorial commentary. Detailed notes are incorporated throughout and a bibliography is also included. This book will be of value to anyone with an interest in Zeno and ancient philosophy.

The program of a physical concept of information is outlined in the framework of quantum theory. A proposal is made for how to avoid the intuitive introduction of observables. The conventional and the Everett interpretations in principle may lead to different dynamical consequences. An ensemble description occurs without the introduction of an abstract concept of information.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 38.1 (2000) 87-101 [Access article in PDF] Collingwood on Re-Enactment and The Identity of Thought Giuseppina D'oro University of Keele Collingwood's The Idea of History is often discussed in the context of the issue of the reducibility/non-reducibility of explanations in the social sciences to explanations in the natural sciences. In the 1950s and 60s, following the publication of Hempel's influential article, "The Function (...) of General Laws in History,"1 many looked at Collingwood's defence of the autonomy of history as providing the appropriate conceptual resources to counter Hempel's claim that explanations in history and in the natural sciences share the same logical structure. Collingwood was recruited as an ally in a number of debates in analytical philosophy of history with a view to clarifying the nature of appropriately historical explanations and the proper subject matter of historical science. In this paper, I wish to consider Collingwood's account of historical understanding from a related but distinct perspective, that is, I wish to consider re-enactment from the perspective of Collingwood's (controversial) claim that thought stands outside time, and that it is because thought stands outside time that it is possible to understand the thoughts of other agents, including those of agents who lived in a distant past. Although Collingwood's account of re-enactment is developed in the context of his philosophy of history, it addresses some very general issues within the philosophy of mind. It is with Collingwood's approach to these general issues that the present paper is concerned: First, I explicate Collingwood's account of re-enactment against the background of his philosophy of mind and, second, attempt to show that one important goal of Collingwood's account of re-enactment is to undermine a certain type of scepticism about the possibility of sharing the thoughts of others, rather than provide a straightforward refutation of this sceptical position. While I believe Collingwood's claim that thought stands outside time to have important repercussions on how to understand [End Page 87] issues more closely related to the philosophy of history, I will not attempt, for reasons of space, to cash out these implications here.In The Idea of History2 the concept of re-enactment is expounded largely via an engagement with an imaginary objector. The position that Collingwood attributes to the imaginary objector can be preliminarily summarized as saying that the objector identifies thoughts with token acts of thinking which can be spatio-temporally located, rather than with the propositional content expressed by those token acts. It is because the objector holds thoughts to be token acts which can be spatio-temporally located that s/he denies that two agents can have or share one and the same thought. Collingwood's reply to the imaginary objector relies on a philosophy of mind that is developed elsewhere3 but whose key elements are presupposed by his discussion of re-enactment in The Idea of History, and essential to an understanding of Collingwood's position.4An important aspect of Collingwood's philosophy of mind concerns his understanding of what is meant by an 'object of thought': When I call a thing subjective I mean that it is or pertains to a subject or conscious mind. When I call it objective I mean that it is or pertains to the object of which such a mind is conscious. I do not call a real rose objective and an imaginary one subjective, or the molecules in it objective and the beauty of it subjective. A real rose I call real and an imaginary rose I call imaginary; and I call them both objective because they are the objects of a perceiving and imagining mind respectively. (SM, 11)5For the sake of clarity I shall refer to the subjective/objective distinction as used by Collingwood as subjective2 and objective2 and to the subjective/objective distinction against which it is contrasted as subjective1 and objective1. Objective1 means existing in... (shrink)

This paper addresses the issue of how science and history of science may help or be helped by Vedic studies. The conclusions drawn are that: 1. Vedic studies are important for the history of Indian science; 2. Modern science, in particular physics, is not a useful source of philosophical ideas that confirm aspects of Vedic studies; 3. Vedic studies will not contribute to modern scientific research; and 4. Vedic studies are nevertheless centrally important for an understanding of Indian history and (...) culture in general.

In this paper we report on our experiences with using network analysis to discern and analyse ethical issues in research into, and the development of, a new wastewater treatment technology. Using network analysis, we preliminarily interpreted some of our observations in a Group Decision Room session where we invited important stakeholders to think about the risks of this new technology. We show how a network approach is useful for understanding the observations, and suggests some relevant ethical issues. We argue that (...) a network approach is also useful for ethical analysis of issues in other fields of research and development. The abandoning of the overarching rationality assumption, which is central to network approaches, does not have to lead to ethical relativism. (shrink)

What is it for a particular to have a property? many proposed analyses of this situation may be called relational accounts. The particular has some relation, R, To some entity p. R may be the relation of falling under, Being a member of, Resembling or "participating." p may be a predicate, A concept, A class, A paradigm instance or a form. A number of arguments seek to prove that all these accounts are involved in various vicious infinite regresses. These arguments (...) are classified, Their resemblances and differences noted, And their soundness assessed. (edited). (shrink)

In this paper I propose a set-theoretical interpretation of the logical square of opposition, in the perspective opened by generalized quantifier theory. Generalized quantifiers allow us to account for the semantics of quantificational Noun Phrases, and of other natural language expressions, in a coherent and uniform way. I suggest that in the analysis of the meaning of Noun Phrases and Determiners the square of opposition may help representing some semantic features responsible to different logical properties of these expressions. I will (...) conclude with some consideration on scope interactions between quantifiers. (shrink)

Background: Demand for organisational ethics capacity is growing in health organisations, particularly among managers. The role of clinical ethicists in, and perspective on, organisational ethics has not been well described or documented in the literature. Objective: To describe clinical ethicists’ perspectives on organisational ethics issues in their hospitals, their institutional role in relation to organisational ethics, and their perceived effectiveness in helping to address organisational ethics issues. Design and Setting: Qualitative case study involving semi-structured interviews with 18 clinical ethicists across (...) 13 health organisations in Toronto, Canada. Results: From the clinical ethicists’ perspective, the most pressing organisational ethics issues in their organisations are: resource allocation, staff moral distress linked to the organisation’s moral climate, conflicts of interest, and clinical issues with a significant organisational dimension. Clinical ethicists were consulted in particular on issues related to staff moral distress and clinical issues with an organisational dimension. Some ethicists described being increasingly consulted on resource allocation, conflicts of interest, and other corporate decisions. Many clinical ethicists felt they lacked sufficient knowledge and understanding of organisational decision-making processes, training in organisational ethics, and access to organisational ethics tools to deal effectively with the increasing demand for organisational ethics support. Conclusion: Growing demand for organisational ethics expertise in healthcare institutions is reshaping the role of clinical ethicists. Effectiveness in organisational ethics entails a re-evaluation of clinical ethics training to include capacity building in organisational ethics and organisational decision-making processes as a complement to traditional clinical ethics education.

Due to the competitive nature of business as a whole, it is sometimes difficult to develop moral relationships with others. However, though friendships are possible in business, most relationships must be kept on the lower level of business acquaintanceship.

Automne 1876: Nietzsche, jeune professeur de philologie à Bâle, brillant élève de Ritschl, part pour Sorrente, invité par son amie Malwida von Meysenbug. C'est son premier voyage dans le Sud : une découverte qui va changer sa vie et le cours de sa philosophie. C'en est fini des tentatives de renouveler la culture allemande au nom de la cause wagnérienne ; l'auteur de La Naissance de la tragédie (1872) commence sa mue. Paolo D'Iorio dresse la carte de cette métamorphose : (...) lectures et discussions, promenades, explorations des environs avec son ami Paul Rée et l'étudiant Albert Brenner ; il fait revivre cette sociabilité joyeuse et confiante qui fertilise l'élan créateur de Nietzsche. C'est à Sorrente que Nietzsche entreprend la rédaction de Choses humaines, trop humaines, dédié à Voltaire. Cette oeuvre, la première sous forme d'aphorismes, inaugure sa philosophie de la maturité. La rupture avec Wagner qu'il verra alors pour la dernière fois, est intellectuellement consommée bien qu'encore cachée. A la suite de ce voyage, Nietzsche abandonnera sa chaire bâloise et entamera une existence de philosophe sous le signe du Midi entre la Suisse, la France et l'Italie. (shrink)

C’est une évidence : on ne parle plus aujourd’hui d’une crise succédant à d’autres crises – et préludant à d’autres encore –, mais de « la crise », qui plus est d’une crise globale qui touche aussi bien la finance que l’éducation, la culture, le couple ou l’environnement. Ce constat témoigne d’une véritable mutation : si à l’origine le concept de krisis désignait le moment décisif dans l’évolution d’un processus incertain permettant d’énoncer le diagnostic (et donc la sortie de crise), (...) nous vivons actuellement précisément l’inverse – le moment où surgissent les incertitudes quant aux causes, aux effets, à la possibilité même d’une issue. Afin d’éclairer ce renversement, Myriam Revault d’Allonnes se penche sur le mouvement d’arrachement au passé et à la tradition qui caractérise la modernité, et qui dissout d’un même élan les anciens repères de la certitude qui balisaient la compréhension du monde. Privé de toute forme de transcendance, l’homme moderne se trouve face à un monde redoutablement ambigu et auto-référentiel, qui a vu s’évanouir tour à tour l’idée de temps nouveaux, la croyance au progrès et l’esprit de conquête, modifiant profondément le rapport de l’homme à son vécu et à ses attentes. C’est à partir de cette expérience du temps d’un nouveau genre, à la fois coupée de ses référents passés et dépourvue de lendemains qui chantent, que cet essai stimulant nous invite à reconsidérer de façon inédite la « crise » dans laquelle nous sommes plongés et à y puiser de quoi aller de l’avant.

J. Angelo Corlett’s response to Leigh Turner defends the current practice of anonymous refereeing in scholarly journals. In reply to him: a slightly refined proposal for signed referees’ reports, with temporarily blind refereeing, would restore to the process of publication, in philosophy at least, the sense of responsibility for rational debate, cooperation, mutual criticism, and simple courtesy which is expected among colleagues in public academic relations, and would also allow more credit for the difficult task for refereeing. Personal observation of (...) the quality of referees’ reports suggests that a gathering of anecdotal evidence would show the need for reform. (shrink)

I discuss issues concerning the philosophical foundations andimplications of quantum field theory, renormalization inparticular. A new understanding of the correspondence principle,an unexpected role of perturbation theory and, most of all, acriterion to reduce the set of consistent theories frominfinitely many to finitely many, are the key concepts of atheoretical set-up that appears to overcome in a natural wayvarious consistency problems of quantum mechanics and offerseveral hints for further developments.

Health care workers with needlestick exposures to patients' blood often request a test of the patient for evidence of infection with human immunodeficiency virus. If the patient refuses the test, a conflict develops between the interests of the health care worker and those of the patient. Traditional approaches to this dilemma attempt to balance the rights or utilities of abstract patients and health care workers. While these approaches have the advantage of offering clear guidelines in advance of conflict, the interests (...) of the actual participants may differ from those used to create the guidelines. In nonmedical settings, conflicts are often resolved efficiently through negotiation and monetary exchanges. Although negotiated monetary settlements between health care workers and patients may be an impractical way to resolve medical conflicts, models developed from these perspectives provide insights into the individual interests of physicians and patients. Changing existing rules about medical record documentation, or increasing the penalties for the misuse of medical information, may satisfy the interests on both sides of the conflict and so represent integrative bargaining solutions. Even so, as the relationship between health care workers and their patients evolves, more explicit strategies for negotiation may become a reasonable solution to the problem of conflict. (shrink)
