AbstractThis paper outlines a hypothetical six-dimension doctrine for military intelligence-gathering in the Akashic domain. The Akashic records are described by esotericists and mystics as a permanent record of all thoughts, feelings, and actions, stored in a kind of cosmic memory bank outside of space and time. Psychics, clairvoyants, and other intuitives purport to read the records, suggesting that development of an operational strategy for accessing such information may be possible. Command oversight, however, would present significant moral challenges, as “hacking” into this information would be a personally intrusive invasion of privacy with serious repercussions for the operators and state sponsors. 相似文献

To remove the influence of spuriously long response times, many investigators compute “restricted means”, obtained by throwing out any response time more than 2.0, 2.5, or 3.0 standard deviations from the overall sample average. Because reaction time distributions are skewed, however, the computation of restricted means introduces a bias: the restricted mean underestimates the true average of the population of response times. This problem may be very serious when investigators compare restricted means across conditions with different numbers of observations, because the bias increases with sample size. Simulations show that there is substantial differential bias when comparing conditions with fewer than 10 observations against conditions with more than 20. With strongly skewed distributions and a cutoff of 3.0 standard deviations, differential bias can influence comparisons of conditions with even more observations. 相似文献
