Ford Doolittle grew up in Urbana, Illinois, and obtained undergraduate and graduate degrees, respectively, at Harvard and Stanford (the latter with Charley Yanofsky). After a postdoc with Norm Pace, he moved to Canada, taking a position at Dalhousie University in Halifax. He has been there ever since, for the last 17 years as a Fellow of the Canadian Institute for Advanced Research, and Directo...

This project investigates the effects of gender in a human-robot collaboration interaction. In the experiment, participants completed four Sudoku-like puzzles with a robot from which they could verbally elicit help. The robot was given the gendered characteristics of a gendered computer generated voice and either the name Charlotte (female condition) or Charley (male condition). Contrary to exp...

Dynamic reduced form models of portfolio credit risk can be distinguished by the way in which the intensity of the default process is specified. In a bottom up model, the portfolio intensity is an aggregate of the constituent intensities. In a top down model, the portfolio intensity is specified without reference to the constituents. This expository article contrasts these modeling approaches. ...

We calculate the most general effective potential for the massless Thirring model in dependence on all local fields of collective fermion–antifermion excitations. We analyse the minima of this potential describing different vacua of the quantum system. We confirm the existence of the absolute minimum found in EPJC 20, 723 (2001) corresponding to a chirally broken phase of the massless Thirring ...
