Nilpotent Spacelike Jorden Osserman Pseudo-riemannian Manifolds

Pseudo-Riemannian manifolds of balanced signature which are both spacelike and timelike Jordan Osserman nilpotent of order 2 and of order 3 have been constructed previously. In this short note, we shall construct pseudo-Riemannian manifolds of signature (2s, s) for any s ≥ 2 which are spacelike Jordan Osserman nilpotent of order 3 but which are not timelike Jordan Osserman. Our example and tech...

From Where I Sit.

AWIS President Susan M. Fitzpatrick can be contacted at [email protected] In 1923 a young woman named Susan Gill left her home in Ireland for New York City. Like many of the “greenhorn” girls making a similar transition to the new country from the old, she first found work as a housekeeper, and eventually transitioned to a position working the night shift at the Tetley tea bag factory. Her husband...

Gaming to Sit Safe

This paper presents a design exploration of full-body interaction games played in cars. It describes how we have designed, implemented, and evaluated the core experiences of three different games, which were all aimed at making sitting properly more fun for players/children while travelling by car. By making the restricted body an integral part of gameplay, we hope to, as a side product of game...
