This article presents a cognitive map proposed to be associated with understanding of the “system concept,” one component of the physics principle of Newton's second low. A definition of the concept is followed by the results of a problem‐solving experiment designed to investigate whether or not good problem solvers possess cognitive structures similar to the one proposed. Think‐aloud protocols were collected as subjects solved a series of physics problems involving Newton's second law. Coding schemes were used to analyze these protocols (...) and to develop a quantitative index intended to reflect the extent to which subjects possessed certain components of the proposed structure. This index proved a highly significant predictor of performance on Newton's second law transfer problems contained in a written exam. In contrast, performance on a set of familiar problems in the same written exam was not a good predictor of performance on transfer problems. These results indicate that cognitive structures that connect the equation ΣF = ma and the concept of choosing appropriate systems are at least part of what constitutes understanding of the principle of Newton's second law. Implications for physics education and problem‐solving research are presented. (shrink)

Epistemological foundationalism can be generally characterized as the thesis that in order for there to be any genuine knowledge at all, there must be some self-authenticating instances of knowledge which epistemically ground the whole edifice. This position can be seen to involve three distinct claims: there are self-authenticating, noninferential pieces of knowledge; these privileged instances can be infallibly recognized as such so as to be able to function in grounding other knowledge claims; and without some such instances functioning in this (...) way, knowledge would have no foundation and skepticism would ensue. Although adherents of this ideal run the gamut from Aristotle to Husserl, it is usually identified with the epistemological problematic introduced by Descartes and Locke. The particular formulations of this general ideal differ to the extent that the self-authenticating instances are recognized as being sense-data, phenomenological essences, or intellectual principles.

Corporate governance is increasingly becoming an issue of global concern, not least because we are more and more living in a corporate world that transcends international boundaries. The main purpose and motivation of this study is to determine how the international community should motivate businesses in fostering exemplary corporate governance, therefore eliminating obstacles to ethically exemplary behavior. The empirical approach utilized here has been applied to 161 businesses, both listed and over-the-counter (OTC) companies, with the results indicating that ethical considerations, (...) corporate governance and organizational performance are inextricably linked and, to an extent, demonstrably proportional. This study also indicates a major finding that family management is a significant mediating variable of the ethical considerations of corporate governance and organizational performance. Finally, this study has developed an operational model of ethical considerations of corporate governance as a consultancy aid for businesses that wish to implement and/or boost their performance in respect to corporate governance.

This paper takes up again the perennial issue of the foundations of empirical knowledge. the general issue is seen to have three distinct though interrelated facets: those of "meaning", "justification", and "truth". first, how is it that our statements about the world acquire meaning; secondly, how is it that our beliefs about the world are justified; and thirdly, in what precisely consists the truth or falsity of the propositional content of our beliefs? answers to these questions are invariably interdependent, and (...) both classically and on the contemporary scene "the foundationalist" and "the coherentist" pictures of knowledge have been the dominant alternatives. after discussing each of these clear though stark views in some detail, i endeavor to construct and defend what i characterize as a mitigated foundational account of knowledge.

In this paper a semantics for dynamic predicate logic is developed that uses sequence valued assignments. This semantics is compared with the usual relational semantics for dynamic predicate logic: it is shown that the most important intuitions of the usual semantics are preserved. Then it is shown that the refined semantics reflects out intuitions about information growth. Some other issues in dynamic semantics are formulated and discussed in terms of the new sequence semantics.

Originally published in 1954, on behalf of the National Institute of Economic and Social Research, this book presents a general review of British economic statistics in relation to the uses made of them for policy purposes. The text begins with an examination, in general terms, of the ways in which statistics can help in guiding or assessing policy, covering housing, coal, the development areas, agricultural price-fixing, the balance of external payments and the balance of the economy. The problems of statistical (...) application are then separately discussed under the headings of quality, presentation and availability, and organization. A full bibliography and reference table of principal British economic statistics are also included. This book will be of value to anyone with an interest in British economic history and statistics.

In this age when idealistic themes such as contextualistic theories of meaning and coherence theories of truth are again becoming commonplace in epistemology and philosophy of science, it should be profitable to recall some of the great representatives of the idealistic tradition in order to reexamine their views on the issues of epistemology and their interpretations of science. The purpose of this paper is to examine, if only partially, idealistic views on this latter issue, i.e., on the nature of science.
