The continuing debate on the relevance and imposition of `Western theories' for explaining educational policy in the Third World is fascinating on a rhetorical level but lacking in the actual `testing' of such theories in a crossnational context. Responding to the general debate, and to a particular paper by Hans Weiler included in this issue of the Oxford Review of Education, on curriculum ref...

Chemical carcinogenicity has been the target of numerous attempts to create predictive models alternative to the animal ones, ranging from short-term biological assays (e.g. mutagenicity tests) to theoretical models. Among the theoretical models, the application of the science of structure-activity relationships (SAR) has earned special prominence. The qualitative approach to SAR has lead to th...

We combine the finite-difference time-domain method with pulse response techniques in order to calculate the light scattering properties of biological cells over a range of wavelengths simultaneously. The method we describe can be used to compute the scattering patterns of cells containing multiple heterogeneous organelles, providing greater geometric flexibility than Mie theory solutions. Usin...

With the number of crowdfunding platforms steadily increasing, it becomes more difficult to attract customers to a particular crowdfunding campaign. This study introduces customer empowerment as a new theoretical concept to study funder participation in crowdfunding. To this end, the paper at hand examines if by systematically empowering funders to participate in crowdfunding product decisions ...

Much of the short-range forces and structures of softly supported DMPC bilayers has been described previously. However, one interesting feature of the measured force-distance profile that remained unexplained is the presence of a long-range exponentially decaying repulsive force that is not observed between rigidly supported bilayers on solid mica substrate surfaces. This observation is discuss...

Come with us to read a new book that is coming recently. Yeah, this is a new coming book that many people really want to read will you be one of them? Of course, you should be. It will not make you feel so hard to enjoy your life. Even some people think that reading is a hard to do, you must be sure that you can do it. Hard will be felt when you have no ideas about what kind of book to read. Or...

Two theoretical models have been proposed to describe long-term dynamics of diversification: the equilibrium model considers the Earth as a closed system with a fixed maximum biological carrying capacity, whereas the expansion model hypothesizes a continuously increasing diversification of life. Based on the analysis of the fossil record of all organisms, Benton suggested contrasting models of ...

Prospects for research in theoretical computer science are discussed. The maintenance of a genuine link between theory and practice is seen as key to the future health of both.
