The past decade has been a time of unparalleled stability for the UK economy. It is more than twelve years since the United Kingdom experienced a single quarter of negative GDP growth. Consumer spending, investment and output have all shown a degree of stability over the past ten years which is unmatched in any decade since the war indeed in the twentieth century. Inflation has been impressivel...

In this paper we sketch a multi-step scenario of a teacher and her classroom, who uses a few computer-based learning tools and their attached teaching analytics views. The tools that are described are extensions of the toolset of the authors (ComIn-M and SMALA) and others; the scenarios should thus serve as user-story in the design of future analytical softwares that support the teacher’s manag...

Shakespeare's Romeo and Juliet starts out as a classic love story: boy meets girl, boy falls in love with girl, boy and girl get married. Of course, it turns into a tragedy when they realize that their relationship is destined to fail. Surprisingly, many offices in corporate America follow a similar-though less morbid--trend. A 2005 survey revealed that 58% of employees had dated someone at wor...

We construct time independent configurations of two gravitating elastic bodies. These configurations either correspond to the two bodies moving in a circular orbit around their center of mass or strictly static configurations.

(1) irii'ii = -gradiU(ql9 ..., qn), i = 1, ..., n, where gradf denotes the gradient with respect to q(. Thoughout this paper we use a single dot over a variable to represent its derivative with respect to time t and a double dot to represent its second derivative with respect to t. The potential energy U has a singularity whenever q(=q^ We write this singular set ^v = {€€(«?: *, = *,}, A = U Au...
