A contribution to the discussion of probabilities and human hair comparisons

The paper by Gaudette and Keeping on "An Attempt at Determining Probabilities in Human Scalp Hair Comparison" in the Journal of Forensic Sciences (Vol. 19, No. 3, July 1974, pp. 599-606) has provoked considerable controversy. This paper highlights two of the sources of the controversy and shows how the probability, 1/4500, quoted by Gaudette and Keeping should be treated with caution. The necessity of the use of a likelihood ratio statistic is described. It is suggested that the hair examination form resulting from the responses to the questionnaire recently distributed by the authors and also the discussions at Quantico (Proceedings of the International Symposium on Forensic Hair Comparisons, 25-27 June 1985, Quantico VA) should be used to facilitate the collection of the data which will be necessary to enable a likelihood ratio statistic to be estimated effectively.     

Perceptions of Danger: The China threat theory

The People's Republic of China witnessed unprecedented growth at the end of the twentieth century and the manner in which it will choose to use its consequent power in the twenty-first century has become a hotly debated topic in foreign policy circles. Some have chosen to interpret China's emergence as an economic and aspiring military superpower as a threat to the national interests of the United States and Asian-Pacific security. This threat has been categorized as ideological, economic, and strategic. This essay explores the China threat theory through an in-depth analysis of the arguments of 'anti-China hands' as outlined in a variety of right wing publications.
