A brief summary of ancient thinkers who contribute to a theory of the physical universe, ranging from Anaximander to Proclus, with a major emphasis on pre-Aristotelian thought. Included in the work are many well-chosen abstracts of primary sources, such as Hippocrates' "On the Sacred Disease" and Parmenides' "On Nature." De Santillana presents a lively account of his materials, together with helpful illustrations. There is a rather insensitive portrayal of Aristotle as a mere synopticist of earlier theories and as primarily (...) concerned with "a tidiness of words."--T. M. G. (shrink)

In this paper we consider an intuitionistic variant of the modal logic S4 (which we call IS4). The novelty of this paper is that we place particular importance on the natural deduction formulation of IS4— our formulation has several important metatheoretic properties. In addition, we study models of IS4— not in the framework of Kirpke semantics, but in the more general framework of category theory. This allows not only a more abstract definition of a whole class of models but also (...) a means of modelling proofs as well as provability. (shrink)

This paper analyses the way in which discourse and argumentation may vary depending on participants’ educational level and gender. Men and women from three different educational levels (literacy, advanced level and university students) participated in discussion groups that debated about women and work, the sharing of housework and the way in which girls and boys are educated. The results showed important differences depending on participants’ educational level and gender. In general, the main differences were related to educational level, while gender (...) tended to interact with educational level, as a moderating factor. (shrink)

With modern technological advances, distance education has become an increasingly important education delivery medium for, for example, the higher education provided by open universities. Among predictive factors of successful learning in distance education, the effects of non-cognitive skills are less explored. Grit, the dispositional tendency to sustain trait-level passion and long-term goals, has raised much research interest and gained importance for predicting academic achievement. The Grit Questionnaire, measuring Perseverance of Effort and Consistency of Interests, has been shown to be a (...) reliable instrument in traditional university student populations. However, the measurement and predictive validity of this questionnaire is still unknown for adult distance education university students who differ from traditional students in various ways. Based on a sample of 2,027 students from a distance education university, this study assessed the psychometric properties of the two-factor structure grit measured by the Grit Questionnaire. The findings suggest that the short form of the Grit Questionnaire is a potentially useful assessment tool for measuring the grit construct for distance learning higher education and that the Consistency of Interests factor is especially relevant to consider the improvement of learning performance for distance education in terms of courses credit and exam attempts. The measurement precision of the Perseverance of Effort factor, however, should be improved in future research to provide higher measurement accuracy and broader item coverage. (shrink)
