Reflections on variability in the blood–breath ratio of ethanol and its importance when evidential breath-alcohol instruments are used in law enforcement

Variability in the blood–breath ratio (BBR) of alcohol is important, because it relates a measurement of the blood-alcohol concentration (BAC) with the co-existing breath-alcohol concentration (BrAC). The BBR is also used to establish the statutory BrAC limit for driving from the existing statutory BAC limits in different countries. The in-vivo BBR depends on a host of analytical, sampling and physiological factors, including subject demographics, time after end of drinking (rising or falling BAC), the nature of the blood draw (whether venous or arterial) and the subject’s breathing pattern prior to exhalation into the breath analyzer. The results from a controlled drinking study involving healthy volunteers (85 men and 15 women) from three ethnic groups (Caucasians, Hispanics and African Americans) were used to evaluate various factors influencing the BBR. Ethanol in breath was determined with a quantitative infrared analyzer (Intoxilyzer 8000) and BAC was determined by headspace gas chromatography (HS-GC). The BAC and BrAC were highly correlated (r = 0.948) and the BBR in the post-absorptive state was 2 382 ± 119 (mean ± SD). The BBR did not depend on gender (female: 2 396 ± 101 and male: 2 380 ± 123, P > 0.05) nor on racial group (Caucasians 2 398 ± 124, African Americans 2 344 ± 119 and Hispanics 2 364 ± 104, P > 0.05). The BBR was lower in subjects with higher breath- and body-temperatures (P < 0.05) and it also decreased with longer exhalation times into the breath-analyzer (P < 0.001). In the post-absorptive state, none of the 100 subjects had a BBR of less than 2 100:1.     

Domestic law and human rights treaty commitments: The Convention against Torture

How human rights treaties will be incorporated and applied domestically must affect how eager states will be to ratify those treaties. This article focuses on two characteristics of domestic legal systems that shape the relationship between international law and domestic law: whether treaties are directly incorporated into domestic law and whether treaties can override ordinary statute. The analysis probes two arguments as to why domestic legal institutions influence ratification decisions, one emphasizing the potential costs associated with ratification and the other emphasizing congruence between domestic values and treaty norms. Survival analysis of ratification of the Convention against Torture reveals that both judicial independence and making treaties equal or superior to statute increase the likelihood of ratification, which is consistent with the norm-congruence thesis. The results suggest new avenues for investigating the relationships between human rights treaties and domestic legal institutions.

Dual engagement: France and the Persian Gulf

With the end of the Cold War international relations began anew without the bipolar constraints of two ideologically opposed superpowers. The Iraqi invasion of Kuwait on 2 August 1990 represented the first challenge to the nascent post‐Cold War Persian Gulf security environment. Within the region, France is once again increasingly active in the economic, political and military fields. The re‐evaluation of Washington's ability to remain engaged at its current levels within the Gulf may be attributed in large part to a growing sensitivity in Riyadh and other Arab capitals to the visible US presence coupled with an American foreign policy which is, at times, inconsistent. The net future effect of contemporary trends may be one in which the Gulf Sheikhdoms welcome French ascendancy and US decline. France has experienced its own foreign policy transformation marked by the leadership of President Chirac. Where President Mitterrand sought the role of power broker in regional affairs, President Chirac seeks increased influence and importance.     

The Yellow Cake Road: Malcolm Fraser,the Ranger Enquiry and Australia's Role in the US International Fuel Cycle Project

The 1975–1983 Fraser Government failed to develop an enrichment industry in Australia but did see the initiation of uranium sales following the adoption of the Ranger Enquiry. Both of these developments were shaped by US nuclear commercial and non‐proliferation policies during the Ford and Carter Administrations, which aimed to restrict the spread of enrichment technology. Fraser would come to realise that it was not a question of private ownership of the nuclear fuel cycle, but of accepting a role for Australia in the international fuel cycle as a supplier of cheap yellowcake.     

For whom does prison-based drug treatment work? Results from a randomized experiment

Objectives

Prison-based therapeutic community (TC) drug treatment followed by community aftercare is widely recognized as the most effective treatment paradigm for drug-dependent offenders. However, few randomized experiments have addressed this question and fewer studies have examined how interactions between treatment modality and individual characteristics may explain variations in outcomes.

Methods

Using a randomized experimental design, this study examined the effects of treatment modality [TC vs. Outpatient (OP) group counseling], individual psychosocial characteristics (e.g., risk, negative affect), and interactions on reincarceration over a 3-year follow-up period. Survival analysis using Cox regression with covariates was used to analyze data obtained from 604 subjects at a specialized drug treatment prison.

Results

The expected advantage of TC failed to emerge. Critical and heretofore unexamined interactions between treatment modality (TC vs. OP), inmate levels of risk, and negative effect help explain these unexpected findings.

Conclusion

The superiority of prison TC to less intensive OP counseling was not supported. The effects of TC appear to be conditioned by critical responsivity factors that have received little empirical attention.     

Concentrations of zolpidem and zopiclone in venous blood samples from impaired drivers compared with femoral blood from forensic autopsies

The concentrations of zolpidem and zopiclone were determined in peripheral blood samples in two forensic materials collected over a 10-year period (2001-2010). The z-hypnotics were determined in venous blood from living subjects (impaired drivers) and in femoral blood from deceased persons (forensic autopsies), with the latter classified as intoxication or other causes of death. The z-hypnotics were determined in blood by capillary column gas chromatography (GC) with a nitrogen-phosphorous (N-P) detector after solvent extraction with n-butyl acetate. The analytical limit of quantitation (LOQ) was 0.02mg/L for zopiclone and 0.05mg/L for zolpidem and these have remained unchanged throughout the study. When death was attributed to drug intoxication (N=918), the median concentration of zopiclone in blood was 0.20mg/L compared with 0.06mg/L for other causes of death (N=1215) and 0.07mg/L in traffic offenders (N=691) (p<0.001). Likewise, a higher median concentration (0.30mg/L) was found in intoxication deaths involving zolpidem (N=357) compared with 0.13mg/L for other causes of death (N=397) or 0.19mg/L in impaired drivers (N=837) (p<0.001). Median concentration in blood of both z-hypnotics were appreciably higher in intoxication deaths when no other substances were identified; 0 70mg/L (N=12) for zopiclone and 1.35mg/L (N=12) for zolpidem. The median concentrations of z-hypnotics in blood decreased as the number of co-ingested substances increased for intoxication deaths but not other causes of death. The most prevalent co-ingested substances were ethanol in autopsy cases and diazepam in the motorists. This large compilation of forensic cases should prove useful when toxicologists are required to interpret concentrations of z-hypnotics in blood samples in relation to cause of death.
