OBJECTIVES We evaluated the protective effectiveness of speed humps in reducing child pedestrian injuries in residential neighborhoods. METHODS We conducted a matched case-control study over a 5-year period among children seen in a pediatric emergency department after being struck by an automobile. RESULTS A multivariate conditional logistic regression analysis showed that speed humps were ...

This paper summarizes the results of a study which examined the accidents that take place at Sri Lankan construction sites as recorded in the Industrial Safety Division (ISD) of the Ministry of Labour. The paper intends to provide a profile of construction accidents in Sri Lanka compared to other industries. In addition, it portrays the occupational and demographic characteristics of the victim...

Ralph’s many academic and organisational achievements have been eloquently told by many and are not the subject of this personal account. Let me explain. When I first met Ralph in the mid 1990s, he struck me as a talkative, overly nice, trying-to-make-up-for-apartheid type of man.

Using conformal field theory methods we construct a metric that describes the distortion of space-time surrounding a D~irichlet!-brane ~solitonic! defect after being struck by another D-brane. By viewing our four-dimensional universe as such a struck brane, embedded in a five-dimensional space-time, we argue on the appearance of a band of massive Kaluza-Klein excitations for the bulk graviton w...
