Comparison of the analytical capabilities of the BAC Datamaster and Datamaster DMT forensic breath testing devices

The State of Michigan uses the Datamaster as an evidential breath testing device. The newest version, the DMT, will replace current instruments in the field as they are retired from service. The Michigan State Police conducted comparison studies to test the analytical properties of the new instrument and to evaluate its response to conditions commonly cited in court defenses. The effects of mouth alcohol, objects in the mouth, and radiofrequency interference on paired samples from drinking subjects were assessed on the DMT. The effects of sample duration and chemical interferents were assessed on both instruments, using drinking subjects and wet-bath simulators, respectively. Our testing shows that Datamaster and DMT results are essentially identical; the DMT gave accurate readings as compared with measurements made using simulators containing standard ethanol solutions and that the DMT did not give falsely elevated breath alcohol results from any of the influences tested.     

Challenging Bipolarity: The Socialist International and the ‘Chilean Democratic Cause’ during the Cold War

This article analyses, the Socialist International's (SI) new international positioning strategies from a transnational perspective, through its relationship with the Chilean cause in the context of the Cold War détente. Focus will be placed on the SI's strong commitment to the Chilean democratic cause after the coup and its sustained activism during the military regime. Drawing from primary sources in various international archives, this article's main goal is to shed light on the SI's positioning regarding Latin America as a way to challenge the bipolar order.
