Entrance Exit

This book highlights human behaviour and architectural considerations for prescriptive code requirements for emergency exits in heritage cultural centers. Closed circuit television camera (CCTV) footage from a Canadian heritage cultural centre was analyzed from three separate unannounced evacuations, where recommendations based on the first two evacuations were implemented for the third. This study aims to (1) develop a baseline for the behaviour and actions of people during the pre-movement and movement stages of emergency egress and evacuation situations and (2) collect behavioural and movement data to aid the fire safety community with the decision process for egress and evacuation strategies and (3) interrogate and highlight architectural barriers in heritage structures with respect to emergency evacuation. The discussion of findings includes occupant behaviour, architectural implications and evacuation modelling and considers the often-conflicting intersection between architectural conservation and fire safety.

An innovator in contemporary thought on economic and political development looks here at decline rather than growth. Albert O. Hirschman makes a basic distinction between alternative ways of reacting to deterioration in business firms and, in general, to dissatisfaction with organizations: one, “exit,” is for the member to quit the organization or for the customer to switch to the competing product, and the other, “voice,” is for members or customers to agitate and exert influence for change “from within.” The efficiency of the competitive mechanism, with its total reliance on exit, is questioned for certain important situations. As exit often undercuts voice while being unable to counteract decline, loyalty is seen in the function of retarding exit and of permitting voice to play its proper role. The interplay of the three concepts turns out to illuminate a wide range of economic, social, and political phenomena. As the author states in the preface, “having found my own unifying way of looking at issues as diverse as competition and the two-party system, divorce and the American character, black power and the failure of ‘unhappy’ top officials to resign over Vietnam, I decided to let myself go a little.”

This book provides all the essential and best elements of Kidger's many courses taught worldwide on lens and optical design. It is written in a direct style that is compact, logical, and to the point--a tutorial in the best sense of the word. "I read my copy late last year and read it straight through, cover to cover. In fact, I read it no less than three times. Its elegant expositions, valuable insights, and up-front espousal of pre-design theory make it an outstanding work. It's in the same league with Conrady and Kingslake." Warren Smith.
