Don't be shocked: power lines are safe!

Article Abstract:

A physicist presents a rebuttal to concerns over the possible ability of power-line fields to cause cancer. J. Robert Ashley bases his findings on informal and nearly random measurements which he suggests may be due to electric fields rather than magnetic fields. Hundreds of studies have already dealt with whether a field effect exists, but proposed cause is a secondary consideration. The cancer most implicated in studies is childhood leukemia, which has a normal incidence of three in 10,000; studies showing a positive correlation indicate a relative risk factor of two to three at the most, and sample sizes are smallest in the areas of highest exposure. Implicit problems include the epidemiological model used., the difficulty of selecting a representative control group and the fact that the same considerations apply to childhood and adult cancers other than leukemia. The scientific consensus today is that statistics yield no indication of any effect on humans of very low frequency (VLF) electromagnetic fields.

Retrospective organization

Article Abstract:

It is reported that things in the work place do not always proceed in the organized method, conveyed by the presentations depicting crisply defined sets of system requirements. Mistakes, ambiguous decisions and mismanagement are always there. The order is retrospectively organized by people without thinking about it and memories get altered to believe in this illusion.
