Data from a national survey of pilots were used to examine the validity of measures for the prediction of aviation accidents that had occurred prior to the survey (retrospective analysis) and accidents that occurred after the survey (prospective analysis). Separate retrospective and prospective analyses were conducted, and 45 measures from the survey were found to be associated significantly with accident involvement in the retrospective analysis. However, only 13 of those 45 measures achieved significance in the prospective analysis. Most of the measures found to be significantly related to accident involvement concerned aviation exposure; the remaining measures related to pilots' perceived and actual level of caution. The study is unique in its use of a cohort design for the examination of aircraft accident risk prospectively, and the results suggest the need for caution in the interpretation of retrospective analyses in this research domain. Actual or potential applications of this research include the design of aviation safety programs and the design or interpretation of studies that address indicators of aircraft accident risk.

is an overall trend in the oil industry to reduce the number of petrol
filling sites and that a valuer must take full account of all known or
potential factors in the surrounding area including the impact of
hypermarket petrol filling stations.

The response on the part of Christians to the ongoing struggle in the Middle East between Israel and the Arab states is limited, restrained and varied. This should not have surprised anyone, for in general Christians do not differ from the great mass of those who make up our nation. We are a people quite generally uninformed about international affairs and not very quickly stirred up by happenings abroad. Some of us are moved by such things, but it takes a Pearl Harbor or a halfdozen years of rapidly accelerating U.S. aggression in Indochina to get a response from us. The average Jew has every reason to be concerned about the breaking of the peace in the Middle East.
