Imagine that a fire breaks out at one or more vertices of a graph, and at each time interval spreads to all neighbouring vertices that have not been protected earlier on. This is the general setup for The Firefighter Problem , which has attracted considerable attention since being introduced in 1995. We survey the directions and results that have been(More)
1 The key role of the individual in the venture start-up process is unquestioned. Yet, attempts to use individual-level variables to predict who will start a business have had limited success. The cognitive literature shows promise in this regard. However, most research strategies emerging from it rely on retrospective accounts from successful founders.(More)
Anti-Müllerian (AMH), a member of the transforming growth factor beta produced by immature Sertoli cells and, to a lesser degree, by granulosa cells from birth to the end of reproductive life, does not affect gonadal determination but has a negative effect upon gonadal development in both sexes. It blocks meiosis in fetal ovaries, leading to loss of germ(More)

The embryo is initially sexually indifferent, and correct sexual development is dependent on gonadal hormone production. Thus, in the male embryo, anti-Müllerian hormone (AMH), secreted by the Sertoli cells of the testis, induces regression of the Müllerian duct, the anlagen of female reproductive tract. This hormone causes ductal epithelial regression(More)
Building on the results of our computer simulation 1 we develop a theoretical description of the motion of a bead, embedded in a network of semiflexible polymers, and responding to an applied force. The theory reveals the existence of an osmotic restoring force, generated by the piling up of filaments in front of the moving bead and first deduced through(More)
A recent literature has fomented considerable interest in multi-dimensional measurement of wellbeing and deprivation. However, increasing the number of dimensions over which various aspects of wellbeing are measured raises concerns regarding the robustness of such measures, the extent to which they relate to individual and societal preferences, and their(More)
This study examines the impact of high-stakes, large-scale, standardized literacy testing on youth who have failed the Ontario Secondary School Literacy Test. Interviews with youth indicate that the unintended impact of high-stakes testing is more problematic than policy makers and educators may realize. In contrast to literacy policy's aims to help promote(More)
