In the last few years, my research has been in geometric group theory, which attempts to understand groups via the spaces upon which they act. The last two decades have seen tremendous progress in our understanding of infinite discrete groups, and many longstanding open problems have been solved using geometric methods. I am particularly interested in coarse negative and non-positive curvature,...

“Experimetrics” refers to formal procedures used in designed investigations of economic hypotheses. Fundamental experimetric contributions by Ronald A. Fisher provided the foundation for a rich literature informing the design and analysis of economics experiments. Key components of this foundation include the concepts of randomization, independence and blocking. Experimetric analysis plays a ce...

The nineteenth century witnessed far-reaching changes in the nature and organization of industrial production. Traditional non-mechanized establishments artisan shops were displaced by mechanized water or steam-driven plants and extensive division of labor increased the average size of firms (Chandler 1977; Sokoloff 1984). In these new mills and "factories", the centralized nature of motive pow...

ION GRAVITY – FROM HIGH TO LOW This pattern is based on Gary L. Craig’s Discussion-Activity-Review-Lab-Review [GLC] pattern and was revised by Jane Chandler. You are about to start a new topic, which is has many levels of abstraction.

In this present study analytical method based on Riccati Equation as for converting the Nonlinear Lakshmanan-Porsezian-Daniel (LPD) equation into the nonlinear ODE and finding soliton solutions of this sustem discused. Obtaining solutions are new and obtained from wave transformation. The obtained results show that the presented method is effective and appropriate for solving nonlinear differen...

The analytical solution of the Chandler–Silbey–Ladanyi Percus–Yevick ~CSL-PY! approximation for multicomponent molecular site–site fluids is presented. The molecules are modeled by a collection of an arbitrary number of hard-sphere sites of any size and geometrical arrangement, provided only that all sites are in contact and the bonding distance is equal to the contact distance between the site...

Learning requires applying limited working memory and attentional resources to intrinsic, germane, and extraneous aspects of the learning task. To reduce the especially undesirable extraneous load aspects of learning environments, cognitive load theorists suggest that spatially integrated learning materials should be used instead of spatially separated materials, thereby reducing the split-atte...
