Due to its extraordinary predictive power and the great generality of its mathematical structure, quantum theory is able, at least in principle, to describe all the microscopic and macroscopic properties of the physical world, from the subatomic to the cosmological level. Nevertheless, ever since the Copen hagen and Gottingen schools in 1927 gave it the definitive formu lation, now commonly known as the orthodox interpretation, the theory has suffered from very serious logical and epistemologi cal problems. These shortcomings were immediately (...) pointed out by some of the principal founders themselves of quantum theory, to wit, Planck, Einstein, Ehrenfest, Schrodinger, and de Broglie, and by the philosopher Karl Popper, who assumed a position of radical criticism with regard to the standard formulation of the theory. The aim of the participants in the workshop on Open Questions in Quantum Physics, which was held in Bari (Italy), in the Department of Physics of the University, during May 1983 and whose Proceedings are collected in the present volume, accord ingly was to discuss the formal, the physical and the epistemo logical difficulties of quantum theory in the light of recent crucial developments and to propose some possible resolutions of three basic conceptual dilemmas, which are posed respectively ~: (a) the physical developments of the Einstein-Podolsky-Rosen argument and Bell's theorem, i. e.

The inventive, argumentative and stylistic possibilities generated by figures in general and the figure antithesis in particular are explored by Jeanne Fahnestock in the field of science. These ideas on the possibilities of antithesis are developed in the analysis of some cases of this figure in the media. This paper explores how antithesis can consist of textual and visual elements, and how various sorts and degrees of opposition are constructed in the figure.

This study explores the role that news coverage plays in the allocation of Japanese development aid. Conceptually, it is expected that democratic foreign policy officials, including those working in bureaucratic governmental structures will try to match the magnitude of their actions with what they expect is the public's perception of the importance of the recipient. News media salience serves an easily accessible indicator of that domestic political importance and, in the case of foreign aid, this suggests that higher levels of (...) news coverage of a less-developed country will lead to higher aid commitments. The statistical analysis demonstrates that the level of news coverage is a statistically significant factor in Japanese aid distributions. More significantly, the analysis demonstrates that separating grant aid from other forms of aid is critical for the empirical examination of the determinants of Japanese aid. (shrink)

Van Belle traces the history of psychology from its roots in Greek philosophy and includes a description of the later influence of the Hebraic-Christian mindset on that history. Subsequently, he follows the journey of psychology through the Middle Ages and the scientific revolution of the sixteenth century. Next, he describes the birth and trajectory of psychology proper during the nineteenth century and closes with a description of a number of the more contemporary schools of psychological thought. The underlying thesis (...) of the text is that the history of psychology gives evidence of both continuity and discontinuity in interaction with one another. Thus, to do justice to the actual history of psychology one must take note of both persisting themata and changing paradigms. (shrink)

Dutch developments on euthanasia have drawn much attention over the years. Defenders and opponents have been telling very different stories about the practice of euthanasia and the frequency of cases, and the Dutch government has been struggling with the legal and moral problems involved. Concern about the procedures followed by physicians as well as questions on the “real” figures led the government to decide to organize an epidemiological study on the extent and the decision making. The results of the study (...) were published in November 1991. Interpretation of the data may lead to a final settlement of the debate on euthanasia and has inevitably led to a revival of the moral debate of the 1970s. For the moment it has been decided that euthanasia will remain officially illegal under the Penal Code. However, in cases where euthanasia does occur, Attorneys General will continue to check the procedures followed by physicians to ensure no abuses have occurred and to safeguard physicians against prosecution. In this contribution, we discuss the development and intertwinement of legal, medical, and moral aspects of euthanasia in The Netherlands and the effects of the empirical studies of 1991, both on definitions and procedures for medical decisions at the end of life.

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)

SummaryIntense, sustained nursing lengthens inter-birth intervals and is causally linked with low natural fertility. However, in traditional settings, the effects of such nursing on fertility are difficult to disentangle from those of nutrition. Results from an prospective, direct observational study of reproductive function in well-nourished Amele women who nurse intensively and persistently but who also have high fertility are here presented. Endocrine measures show that ovarian activity resumes by median 11·0 months postpartum. Median duration of postpartum amenorrhoea is 11·3 months, (...) time to next conception is 19·0 months, and the inter-birth interval is 28·0 months. Average life time fertility is 6·8. High fertility in Amele women is due both to refractoriness of reproductive function to suckling stimuli, and to maintenance of equivalent age-specific fertility rates across the reproductive life span.

An experimental study is reported which investigates the differences in interpretation between content conditionals (of various pragmatic types) and inferential conditionals. In a content conditional, the antecedent represents a requirement for the consequent to become true. In an inferential conditional, the antecedent functions as a premise and the consequent as the inferred conclusion from that premise. The linguistic difference between content and inferential conditionals is often neglected in reasoning experiments. This turns out to be unjustified, since we adduced evidence on (...) the basis of a quantitative and a qualitative analysis that this difference has a manifest psychological relevance. For the inferential conditionals, participants appear to retrieve the order of events of the original content conditional on which it was based, before they start reasoning with it. The implications of this finding for reasoning research and linguistics will be discussed. (shrink)
