Statefinder diagnostic is a useful method which can differ one dark energy model from the others. The Statefinder pair {r, s} is algebraically related to the equation of state of dark energy and its first time derivative. We apply in this paper this method to the dilaton dark energy model based on Weyl-Scaled induced gravitational theory. We investigate the effect of the coupling between matter...

Existing turnover models have been developed and tested almost exclusively in Anglo cultures. Thus, there is reason to question whether these models apply to workers elsewhere. We addressed this question using as participants 47 Mexican maquiladora workers. Through interview responses analyzed using a variation of grounded theory-building, we inductively created a model of voluntary turnover wi...

The aim of this study is to investigate the improvement in strength a top-hat profile hollow-section beam used vehicle structure by attaching different shapes internal reinforcements. base was first considered as hat-shape which jointed flat plate using spot-welds. Three types sheet metal reinforcements were formed and attached inside beam’s structure. Then, they tested experimentally under low...

Stephen B Maurer ([email protected]) received his Ph.D. from Princeton in 1972, under A. W. Tucker. He is a mathematics professor at Swarthmore College, where he was also an undergraduate. He is coauthor of Discrete Algorithmic Mathematics, with Anthony Ralston. At one time he chaired the MAA high school contests, and he has written guides for undergraduates on writing mathematics. At par...

JCB • VOLUME 203 • NUMBER 3 • 2013 378 W hat can you learn about a cell just by looking at it? Quite a lot, as it turns out. A cell’s shape can tell you about its behavior and its function in the body, just for a start. And, as Chris Bakal can attest, a cell’s shape can also tell you a lot about the signaling pathways at work. Bakal has been interested in cellular signaling pathways ever since ...
