Abstract:
This is an account of my 8-year tour as Human Factors editor during the last decade of the past century. I accepted this appointment with the understanding that the journal, although highly successful, was entering a period of transition during which problems were surfacing that would require some strategic redirection. Together with Human Factors and Ergonomics Society staff and my editorial board, which in addition to peer review I relied on heavily for advice on journal policy, we effected a number of changes. In this article, I review those changes along with the issues they were designed to address and the reasoning behind each. It remains for the reader to judge whether the net effect of these changes has been for the better.

Types of Non-structural Cracks in Concrete
Plastic shrinkage cracks typically form within hours after the concrete is poured. The concrete's surface dries faster than the bottom, creating tensile stress that the still-plastic concrete cannot withstand, leading to diagonal or randomly patterned cracks on the concrete surface.

Design Example: Joints in Concrete Pavements
Contraction joints are typically formed by sawing a groove into the concrete shortly after it has hardened. This creates a weakened vertical plane, deliberately encouraging cracking at...
