There has been, in Canada as elsewhere, a recent resurgence of interest in the distribution of earnings. One reason is that trends in real earnings have been diverging and earnings inequality has been on the rise. Many related questions emerge. Which particular groups – women as compared to men, younger versus older workers, and so on – have been doing better or worse than others? Where has ine...

Below are occasional papers on meteorological history. They include papers about the history of the Met Office, meteorological services leading to D-Day and many other topics. The image on the right shows a weather map from June 5 1944, the day before D-Day. No 14 The History of the first twenty-five years of radar meteorology in the United Kingdom by Richard Probert-Jones [14]

In this paper we consider two types of dimension that can be defined for products of one-dimensional topologically totally transcendental (t.t.t) structures. The first is topological and considers the interior of projections of the set onto lower dimensional products. The second one is based on algebraic dependence. We show that these definitions are equivalent for ω-saturated one-dimensional t...

Computer systems researchers have begun to apply the Foreground-Background (FB) scheduling discipline to a variety of applications, and as a result, there has been a resurgence in theoretical research studying FB. In this paper, we bring together results from both of these research streams to provide a survey of state-of-the-art theoretical results characterizing the performance of FB. Our emph...

■ The recent resurgence of vigilantism in India connects both to the neo-liberal project of outsourcing security, as well as to a longer history of porous boundaries between states and powerful elements in society. When practiced by subaltern groups, it also reflects the failure of the judicial system. This article explores the moral plurality evoked by different forms of vigilantism and their ...

Global games are widely used to predict behaviour in games with strategic complementarities and multiple equilibria. We establish two results on the global game selection. First, we show that it is independent of the payoff functions of the global game embedding, though (as is well-known) it may depend on the noise distribution. Second, we give a simple sufficient criterion for noise independen...

The spreading of an epidemic depends on the connectivity of the underlying host population. Because of the inherent difficulties in addressing such a problem, research to date on epidemics in networks has focused either on static networks, or networks with relatively few rewirings per timestep. Here we employ a simple, yet highly non-trivial, model of dynamical grouping to investigate the exten...

We generalize Gel’fond’s criterion of algebraic independence to the context of a sequence of polynomials whose first derivatives take small values on large subsets of a fixed subgroup of C, instead of just one point (one extension deals with a subgroup of C).

Classroom discussions relating to the modelling of physical phenomena has experienced a resurgence in recent years. One problem that is accessible to students and mathematically tractable is the motion of skydiver. The basic \parachute problem" is formulated and solved. A simple analysis of the problem raises questions about the applicability of this model. Real-life data is used to propose an ...
