Data taken by the Mark II detector at the PEP storage ring was used to measure the rate of dilepton production in multihadronic events produced by e+e- annihilation at √s=29 GeV. We determine the probability that a hadron initially containing a b quark decays to a positive lepton to be 0.17-0.08+0.15, with 90% confidence level limits of 0.06 and 0.38. © 1990.

The central issue is that of identifying and understanding the fundamental principles of morality but the book also discusses the place of rules in moral thought, the nature of obligation, the relation between morality and religion and that of being moral and rational.

Kant was among the first philosophers to recognize that modalities come in many varieties, and that there are systematic connections among them--an insight which has since been confirmed by the multitude of applications of the basic techniques of formalized modal logic. In particular, He recognized an affinity among what are now called doxastic and epistemic logics, As well as with a logic of judging which has not exact counterpart in contemporary thought. This paper will be concerned with the explication of (...) the theory of judgment in its relation to the logics of belief and knowledge. It will seek to show that there is a clear and consistent way to translate Kant's notions of modality into modern symbolic terminology, And that the relations he took to hold among them are well-grounded in his philosophy of logic.

The King Report on Corporate Governance (1994) evoked unprecedented interest in corporate governance in South Africa. This does not mean that corporate governance was not an issue of concern before the release of this historical report. To the contrary, corporate governance in its broader sense has been at stake since the inception of the first publicly owned companies in South Africa. This article intends to give an overview of corporate governance in South Africa. It starts by making a distinction between (...) broad and narrow conceptions of corporate governance. Before applying this distinction to the practice of corporate governance in South Africa, a brief overview of the corporate landscape in South Africa is provided. Then the South African situation with regard to broad and narrow corporate governance respectively is analysed. The article ends with a discussion of the review of corporate governance that currently is in the making in South Africa. Throughout the article both the financial and ethical dimensions of corporate governance is attended to. (shrink)

This book offers the first historical treatment and analytic analysis of the problem of the criterion. It provides analyses of the ancient and modern characterizations of the problem and a resolution of each. My purpose is to show that there are at least two versions of the problem, one posed by a Pyrrhonian sceptic and one by a dogmatic sceptic. I show that both versions have a dissolution. Then, by examining the presuppositions of the dogmatic sceptic, I demonstrate that the (...) sceptic's position is self-undermining. I argue that meta-epistemological scepticism is much less reasonable than some forms of meta-epistemic cognitivism. (shrink)

There is great skepticism about the admittance of expert normative ethics testimony into evidence. However, a practical analysis of the way ethics testimony has been used in courts of law reveals that the skeptical position is itself based on assumptions that are controversial. We argue for an alternative way to understand such expert testimony. This alternative understanding is based on the practice of clinical ethics.

This biography provides a stimulating and coherent blend of scientific and personal narratives describing the many achievements of the theoretical physicist Herbert Fröhlich. For more than half a century, Fröhlich was an internationally renowned and much respected figure who exerted a decisive influence, often as a 'man ahead of his time', in fields as diverse as meson theory and biology. Although best known for his contributions to the theory of dielectrics and superconductivity, he worked in many other fields, his most (...) important legacy being the pioneering introduction quantum field-theoretical methods into condensed matter physics in 1952, which revolutionised the subsequent development of the subject. Gerard Hyland has written an absorbing and informative account, in which Herbert Fröhlich's magnetic personality shines through. (shrink)
