Determination of mouth alcohol using the Dräger Evidential Portable Alcohol System

Drivers suspected of alcohol intoxication are observed for a period of 15 min prior to quantitative breath alcohol testing. This is to preclude the interference of alcohol-based substances such as cough medicine, mouthwash, and breath spray just prior to actual evidential testing. To determine whether a 15 min observation period was necessary when performing evidential breath tests in the field, a mouth alcohol experiment was performed using the Dräger Evidential Portable Alcohol System (EPAS). Five types of alcohol beverages and the effects of expectorating versus swallowing were tested on twenty-five volunteer subjects. Serial measurements of breath and blood alcohol levels were performed at fixed time intervals. All alcohol beverage types gave two sequential measurements within 0.02 g/210 L of each other before 15 min had passed. Fifteen minutes was necessary to ensure there was no residual mouth alcohol. If the 15 min waiting period was not observed, the safety feature of the EPAS requiring two sequential measurements 2 min apart within 0.02 g/210 L would not ensure against mouth alcohol interference.     

In Praise of smallholders

In this review article, Robert Netting's book, Smallholders, Householders. Farm Families and the Ecology of Intensive Sustainable Agriculture ‐ the product of a lifetime of study and fieldwork by an American anthropologist, schooled in cultural ecology ‐ is considered. The book, which is essentially about adaptations to population increase in different ecological contexts, is dedicated to the defence of smallholders against both Right and Left. It is seen as having some several excellent qualities, not least the relevance of its central stress on ecology. But it is criticised, inter alia, for its attempt to explain land tenure by land use rather than social struggle. The absence of any awareness of Narodnik ecological thought on the peasantry is noted.

If Brain Scans Really Detected Deception,Who Would Volunteer to be Scanned?

Abstract: Recent neuroimaging studies investigating the neural correlates of deception among healthy people, have raised the possibility that such methods may eventually be applied during legal proceedings. Were this so, who would volunteer to be scanned? We report a “natural experiment” casting some light upon this question. Following broadcast of a television series describing our team’s investigative neuroimaging of deception in 2007, we received unsolicited (public) correspondence for 12 months. Using a customized template to examine this material, three independent assessors unanimously rated 30 of an initial 56 communications as unequivocally constituting requests for a “scan” (to demonstrate their author’s “innocence”). Compared with the rest, these index communications were more likely to originate from incarcerated males, who were also more likely to engage in further correspondence. Hence, in conclusion, if neuroimaging were to become an acceptable means of demonstrating innocence then incarcerated males may well constitute those volunteering for such investigation.     

Alexandre 1er et le regime representatif

Summary

Alexander I and Representative Government

This analysis of the attitudes of Alexander I towards representative government is based on fifty years of work on Russian political history, and in particular on a study of the international organization of the post‐Napoleonic peace and, more recently, the reign of Alexander I.

In the light of recent events in Russia, this essay suggests some obvious comparisons between Alexander I and Gorbachev. Both wanted to liberalize the government of their empire without damaging the legitimacy of the new institutions to be created with respect to the existing regime. Both were thrown out of power, the former to put a stop to reforms, the latter to speed them up, at the risk of destroying the legitimacy of the central authority over the various parts of the empire.     

Be Wary of Asian Triumphalism

American‐led globalization has enabled the third great powershift of the last five hundred years—the “rise of the rest” following on the rise of the West and then the rise of the US as the dominant power in the West. When China, India, Brazil, Turkey and the rest sit at the table of global power with the West what will the world order look like? Will it be post‐American? Will it be culturally non‐Western, but play by the same rules of an open international order laid down by the American's after World War II? In the following pages, leading American and Asian intellectuals ponder these questions.
