Blood alcohol concentrations (BAC) and corresponding breath alcohol concentrations (BrAC) were determined for 21,582 drivers apprehended by New Zealand police. BAC was measured using headspace gas chromatography, and BrAC was determined with Intoxilyzer 5000 or Seres Ethylometre infrared analysers. The delay (DEL) between breath testing and blood sampling ranged from 0.03 to 5.4 h. BAC/BrAC ratios were calculated before and after BAC values were corrected for DEL using 19 mg/dL/h as an estimate of the blood alcohol clearance rate. Calculations were performed for single and duplicate breath samples obtained using the Intoxilyzer (groups I-1 and I-2) and Seres devices (groups S-1 and S-2). Before correction for DEL, BAC/BrAC ratios for groups I-1, I-2, S-1, and S-2 were (mean+/-SD) 2320+/-260, 2180+/-242, 2330+/-276, and 2250+/-259, respectively. After BAC values were adjusted for DEL, BAC/BrAC ratios for these groups were (mean+/-SD) 2510+/-256, 2370+/-240, 2520+/-280, and 2440+/-260, respectively. Our results indicate that in New Zealand the mean BAC/BrAC ratio is 19-26% higher than the ratio of the respective legal limits (2000).  相似文献

This Article examines whether a participant in a clinical research trial for a drug obtains material nonpublic information about the drug and its manufacturer or licensor and, if so, whether the participant may lawfully trade securities based on that information. This issue has been noted but not examined in depth in several articles in recent years. After an introduction to the federal law of insider trading and a discussion of relevant aspects of a supervised research trial, the Article concludes that, absent an agreement to the contrary, the participant would be free to trade securities based on any material nonpublic information learned in the trial. The author evaluates the extent to which the information is material and nonpublic and then presents the policy issues surrounding whetherthe participantshould be precluded from trading when in possession of material nonpublic information gained as a result of participation in the trial. While not resolving the competing policy considerations, including the value of allowing participants to make disclosure of their experiences in the trial before publication of the results in a peer reviewed journal, the Article presents an approach for preventing the misuse of material nonpublic information gained in the clinical trial context, by obtaining an agreement from the participant, and an agreement from the limited circle of persons to whom the participant should be allowed to make disclosure in any event (such as his personal physician and family members), that would render any trading by them unlawful under the federal law of insider trading.  相似文献
