Objective: The study objectives were to identify factors affecting extension ladders' angular positioning and evaluate the effectiveness of two anthropometric positioning methods. Background: A leading cause for extension ladder fall incidents is a slide-out event, usually related to suboptimal ladder inclination. An improved ladder positioning method or procedure could reduce the risk of ladde...

background: positive attitude leads to a more successfully implementation of a change. we investigated the effect of attitudes of stakeholders toward a program on their prioritization of the program components for selecting the key question of a theory-driven evaluation with concept mapping method. materials and methods: during a brainstorming session, stated statements defined the program comp...

In the spring of 1965, Dr. Beeson decided to leave the chairmanship of Internal Medicine at Yale for the Nuffield Chair in Internal Medicine at Oxford. With this decision he brought to an end a fruitful and exciting period in the development of the Yale Medical School. In recognition of his contributions to the institution in which he played so important a part, the editors of the YALE JOURNAL ...

We consider a discrete-time probabilistic inference system where the conclusions and inputs are probability measures on measurable spaces X,X and Y,Y respectively. We are given a kernel N from X to Y (N : X × Y → [0, 1]), which represents the way information about states of affairs (represented by X) is transmitted to a receptor (represented by Y ). Suppose that at time t = i the conclusion is ...
