Cross-cultural science education: A cognitive explanation of a cultural phenomenon

Abstract: Recent developments in concept learning and in science-for-all curricula have stimulated our interest in two fields of study: how students move between their everyday life-world and the world of school science, and how students deal with cognitive conflicts between those two worlds. In the first field of study, Aikenhead conceptualized the transition between a student's life-world and school science as a cultural border crossing.In the second field, Jegede explained cognitive conflicts arising from cultural dif- ferences between students' life-world and school science in terms of collateral learning. This article (a) synthesizes cultural border crossing with its cognitive explanation (collateral learning) and (b) demon- strates by its example the efficacy of reanalyzing interpretive data published in other articles. The synthe- sis provides new intellectual tools with which to understand science for all in 21st-century science class- rooms in developing and industrialized countries. © 1999 John Wiley & Sons, Inc.

Measuring market orientation: A multi‐factor, multi‐item approach

Abstract: The marketing literature reflects remarkable inconsistency in defining two of its most frequently used terms, “the marketing concept” and “market orientation”. Through a critical review of the marketing literature and an empirical analysis of data collected from 248 Canadian firms, the authors established a four‐component measure of “market orientation”. The resulting multi‐factor, multi‐item instrument provides a foundation for future studies.

Multisymplectic Geometry, Variational Integrators, and Nonlinear PDEs

Abstract: This paper presents a geometric-variational approach to continuous and discrete mechanics and field theories Using multisymplectic geometry, we show that the existence of the fundamental geometric structures as well as their preservation along solutions can be obtained directly from the variational principle In particular, we prove that a unique multisymplectic structure is obtained by taking the derivative of an action function, and use this structure to prove covariant generalizations of conservation of symplecticity and Noether' s theorem Natural discretization schemes for PDEs, which have these important preservation properties, then follow by choosing a discrete action functional In the case of mechanics, we recover the variational symplectic integrators of Veselov type, while for PDEs we obtain covariant spacetime integrators which conserve the corresponding discrete multisymplectic form as well as the discrete momentum mappings corresponding to symmetries We show that the usual notion of symplecticity along an infinite-dimensional space of fields can be naturally obtained by making a spacetime split All of the aspects of our method are demonstrated with a nonlinear sine-Gordon equation, including computational results and a comparison with other discretization schemes
