In this paper, we characterize those external rays that land on the bounded Fatou components of hyperbolic and parabolic quadratic maps. For those maps not in the main cardioid of the Mandelbrot set, we prove that the arguments of these rays form a Cantor subset of the circle at infinity. Our techniques involve both the orbit portraits of Goldberg and Milnor that relate the dynamic and parameter planes and the Thurston theory of laminations for quadratic maps. [ABSTRACT FROM AUTHOR]

In the context of the much-publicised moves within local government from traditional Personnel Management to new Human Resource Management (HRM) systems, this article explores the extent to which line managers' day-to-day people management practices had changed as a consequence of their local authority's formal adoption of HRM policies. While many of these managers had made real and substantial changes in their people management activities, it was nevertheless clear that barriers remained to the full realization of the HRM ideal, with potentially adverse consequences for the managers' motivation and performance levels and for overall organizational effectiveness.

The article explores the impact of adopting new management systems on the work satisfaction levels experienced by middle managers, focusing on a case-study analysis of an English shire county council. Researchers found evidence to suggest a less positive attitude to organisational and management changes among the public sector managers. Evidence of increased work pressures also emerges from most of these studies of middle managers. Results of the case study research indicate that the most significant sources of job dissatisfaction for managers were the lack of job security and restricted opportunities for promotion.

A biography of mathematician Robert L. Devaney is presented, to whom this special issue of "Journal of Difference Equations and Applications" is dedicated. Devaney was born on April 9, 1948, and was brought up in Methuen, Massachusetts. He he did his graduation at the University of California at Berkeley during 1969-1973, and received his Ph.D. in 1973. Devaney chaired the Department of Mathematics at Boston University during 1983-1986, and was promoted to Professor of Mathematics in 1986.
