We explore the extent to which Anderson's (1987) theory of knowledge compilation can account for the relationship between instructions and practice in learning to use a simple device. Bibby and Payne (1993) reported experimental support for knowledge compilation in this domain. This article replicates the finding of a performance cross‐over between instruction type and task type that disappears with practice on the tasks. The research is extended by using verbal protocols to model the strategies of novice and more experienced (...) individuals. Production system models of these strategies suggest that knowledge compilation only provides an adequate account of practice for one of two Instruction groups. To model the strategy shifts for the second group, we employ a “procedure modification heuristic” (after Neches, 1987), which relies on access to a declarative model of the configuration of the device. This suggests that instructionally derived declarative knowledge may have a subtle ongoing effect on the changes in procedural knowledge with practice. (shrink)

An ongoing topic of debate in our times is how exactly the media affects the public. Hakanen analyzes that debate as it has developed in media effects research in order to reveal the changes from a modern to a postmodern self.

This paper discusses the vast continuum between the letter of the law (legality) and the spirit of the law (ethics or morality). Further, the authors review the fiduciary duties owed by the firm to its various publics. These aspects must be considered in developing a corporate code of ethics. The underlying qualitative characteristics of a code include clarity, comprehensiveness and enforceability. While ethics is indigenous to a society, every code of ethics will necessarily reflect the corporate culture from which that (...) code stems and be responsive to the innumerable situations for which it was created. Several examples have been provided to illustrate the ease of applicability of these concepts. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:80 HISTORY OF PHILOSOPHY Gilson often contrasts the God of Aquinas, who is esse, with the God of Augustine, who is essentia. This difference in terminology is taken as emphasizing the essentialist character of Augustine's thought. However, Professor Anderson maintains that essentia should not be regarded as equivalent to the Thomistic notion of essence. F,ssentia is derived, according to Augustine, from esse and is most equivalent to the Thomistic (...) ens. Hence, according to Anderson, Augustine was not ignoring or slighting the factor of existence when he referred to God as essentia. Once again, Anderson's point is valid only if we grant that esse meant "to exisff' for Augustine and could not be interpreted as meaning "to be unchangeable." That there is any doubt that esse meant "to exist" for Augustine seems to be ruled out by Anderson (p. 40). One of Anderson's most interesting theses is the suggestion that the Augustinian distinction between being and non-being is substantially the same as the Thomistie distinction between essence and existence. For Augustine God alone is esse itself, while all creatures are limited by non-esse, i.e., they share in both esse and non-esse. Similarly, for Aquinas only God is esse itself, while all creatures merely possess esse. It is evident that for both philosophers the distinction between what is esse itself and what is not csse itself provides an important way of distinguishing between God and creatures. How much more alike the two distinctions are will depend on how the notion of esse is interpreted by Augustine and Aquinas. One problem is bound to arise: If for Aquinas the "proportionality" of being is to be found in the relationship between esse and essentia in ens, while for Augustine essentia ---- ens, then either Augustine does not have a Thomistic notion of the analogy of being or it must be shown what Augustine 's equivalent for the Thomistic essentia would be. Non-being does not seem adequate for such a role. A good portion of Professor Anderson's essay is devoted to discussing Augustinian metaphysics precisely in the areas in which Gilson claims that Augustine's essentialism creates problems for Augustine the Christian. These include the problems of proving the existence of God, creation and the nature of participation. It is pointed out that many of Augustine's remarks which have frequently been supposed to be of Neoplatonic inspiration are in fact based upon Scripture as far as the Saint is concerned. Although I find some portions of his essay obscure, on the whole I should say that Professor Anderson's study is quite exciting and a considerable challenge to those who are tempted to draw striking contrasts between the "essentialism" of Augustine and the "existentialism" of Aquinas. BRUCE GARSIDE McGiU University Eight Philosophers o] the Italian Renaissance. By Paul Oskar Kristeller. (Stanford, California: Stanford University Press, 1964.Pp. ix -~ 194.$5.00.) The eight chapters constituting the main body of this volume, devoted in succession to Petrarch, Valla, Ficino, Pieo, Pomponazzi, Telesio, Patrizi, and Bruno, are based on the Arensberg Lectures which were delivered by Professor Kristeller in 1961 at Stanford University. Footnotes and bibliographical references have been added, and as an appendix there is included an essay on "The Medieval Antecedents of Renaissance Humanism" which, though delivered as a lecture on several occasions, is here printed for the first time. The purpose of the series of eight lectures, as Kristeller indicates in his short preface, was "to give a brief survey of Italian thought during the Renaissance period". The aspects of Italian Renaissance thought, represented by the authors selected for discussion, are those traditionally described as humanism, Florentine Platonism, Paduan Aristotelianism, and speculative philosophies of nature. As representatives of the humanist movement Petrarch and Valla are selected, not merely because of their prominence but in order to make clear that Renaissance humanism cannot be identified with preference for a particular philosophical tradition. Petrarch preferred Plato to Aristotle, Augustine to Aquinas, and Cicero and Seneca to the Epicureans, whereas Valla preferred the Epicurean philosophy to that of the Stoics or Platonists, and appealed to Quintilian more than to Cicero in his proposals for a reform of...

A veritable tidal shift in Herder scholarship has taken place over the last quarter century, primarily but not exclusively in German. This review essay seeks to evoke the richness and vitality of this revival with the hope of persuading American academics that some ill-founded opinions still circulating concerning Herder's "irrationalism" and chauvinistic, even racist nationalism, and his philosophical naivety and literary effrontery, might at last be put to rest. The recent revival has brough sharply to the fore two crucial aspects (...) of Herder. First, there is the contribution of Herder's thought to the emergent cultural and social sciences. Second, for Herder the "science of man" was also a natural science: the division between the humanities and the natural sciences that has been such a hallmark of the age from Kant until very recently did not exist for Herder.
