    On Kant's first insight into the problem of space dimensionality and its physical foundations

    In this article it is shown that a careful analysis of Kant's "Thoughts on the True Estimation of Living Forces" leads to a conclusion that does not match the usually accepted interpretation of Kant's reasoning in 1747, according to which the Young Kant supposedly establishes a relationship between the tridimensionality of space and Newton's law of universal gravitation. Indeed, it is argued that this text does not yield a satisfactory explanation of space dimensionality, actually restricting itself to justify the tridimensionality of extension.Comment: 14 page

    Adjoint exactness

    Plato's ideas and Aristotle's real types from the classical age, Nominalism and Realism of the mediaeval period and Whitehead's modern view of the world as pro- cess all come together in the formal representation by category theory of exactness in adjointness (a). Concepts of exactness and co-exactness arise naturally from ad- jointness and are needed in current global problems of science. If a right co-exact valued left-adjoint functor ( ) in a cartesian closed category has a right-adjoint left- exact functor ( ), then physical stability is satis ed if itself is also a right co-exact left-adjoint functor for the right-adjoint left exact functor ( ): a a . These concepts are discussed here with examples in nuclear fusion, in database interroga- tion and in the cosmological ne structure constant by the Frederick construction

    Investigating the psychological and emotional dimensions in instructed language learning: obstacles and possibilities

    Get PDF
    In this article I put forth the core argument that Second Language Acquisition (SLA) needs to account for the psychological and emotional dimensions of second language (L2) learning, but that a number of epistemological and methodological difficulties must be surmounted before this new research program can be a reality. To illustrate my arguments, I examine in depth 2 research programs developed by my colleagues and me over the last decade: research on extraversion as a psychological variable investigated within the tradition of individual differences in SLA, and research on the expression of emotion in the L2. Throughout the article, I argue against research isolationism and for more interdisciplinarity in the field of instructed SLA. I contend that research on instructed SLA would benefit from an increased methodological and epistemological diversity and that a focus on affect and emotion among researchers might inspire authors of teaching materials and foreign language teachers to pay increased attention to the communication of emotion and the development of sociocultural competence in a L2

    A Resource Handbook for Planning and Implementing an Integrated Preschool Program

    The purpose of this project was to design and develop a resource handbook to assist teachers and administrators responsible for implementing an integrated preschool program. To accomplish this purpose, research and literature relative to current integration delivery models, primarily those in Washington State were reviewed. The handbook developed was piloted in the Taholah, Washington School District
