Carbon monoxide concentrations in the 2009 Victorian Bushfire disaster victims

Blood was available for the estimation of carboxyhemoglobin saturation (COHb) in 30 of the 173 persons who died in the Victorian bushfires in February 2009. The ages of these 30 deaths ranged from 3 to 80 years and there were 8 females. 13 cases (43%) were considered negative (less than 5% COHb), 12 (40%) were between 5 and 40% COHb, 2 (6.7%) between 40 and 50% and 3 (10%) were greater than 50% COHb. There were 6 persons either found within a building or a car and the COHb in these cases ranged up to 69% (mean 50%). There were 5 cases where the location was unable to be determined as either indoor or outdoor due to the extensive nature of the fire. The remaining 19 deceased persons were all located outside in the open and the concentration of COHb in these cases ranged up to 30% (mean 19%). Hydrogen cyanide was only detected in two deceased persons at concentrations of 0.5 and 2.7 mg/L, respectively. 13 deceased were found to have soot in the airways following necropsy but this did not correlate with the COHb levels.     

Polarized preferences versus polarizing policies

Much of contemporary political debate in the United States focuses on the issue of polarization: specifically, its causal antecedents and its consequences for policymaking and political conflict. In this article, we argue that partisan preference polarization—conventionally defined as the difference in the favored policy positions of legislators from the two major parties—is not a sufficient statistic for potential political conflict in national politics . Rather, a well-defined measure of potential conflict must take into account (1) the locations of status quo policies and proposed alternatives; and (2) the shape of underlying utility functions. We propose measures of the likely contentiousness of a given status quo policy and of a proposal to move that policy. We then demonstrate the usefulness of these measures using estimates of utility function and final passage vote parameters on enacted legislation from the 111th US Senate (2009–2011).     

The Reporter''s Dilemma: News Gathering as Negotiation

Bush and Folger (1994) in The Promise of Mediation articulated distinctions between Individualist and Relational ideology, and linked them to specific theoretical orientations to mediation practice, problem-solving and transformative, respectively. Yet, a question persists as to whether these distinctions produce any material differences in practice. This question is approached here through an examination of a single construct in the mediation literature, empathy. The author proposes that the Individualist and Relational ideological frameworks have material implications for the concept and the practice of fostering empathy between the parties to a mediation: The problem-solving framework fosters a social interaction which can be understood as transactional empathy while the transformative framework fosters an interaction described as relational empathy.     

Coercive Leadership

We develop a model of leadership in which an informed leader has some degree of coercive influence over her followers (agents). Agents benefit from coordination but face two distinct challenges: dispersed information and heterogeneous preferences. The leader's coercive power facilitates coordination by weakening the effect presented by both of these challenges through “binding” agents to a strategically chosen policy. The leader's policy choice becomes more informative to the agents about the leader's privately held information as her coercive capacity increases. By adjusting her policy choice in response to available private and public information, the coercive leader achieves her preferred average of agents' actions, and in so doing, neutralizes the possibly deleterious coordinating influence of public information. We develop implications of our analysis for understanding autocratic leadership in different political and organizational contexts.     

Game Theory, Information, and Deliberative Democracy

We contend that, with a suitably broad notion of rationality and a diverse set of motivations, the game-theoretic tradition is particularly well suited for generating insights about effects of deliberative institutions and that progress in the development of deliberative democratic theory hinges on making proper sense of the relationship between game-theoretic and normative theoretic approaches to deliberation. To advance this view, we explore the central methodological issues at the core of that relationship and address the arguments raised against the relevance of game-theoretic work on deliberation. We develop a framework for thinking about the differences in how the normative and the game-theoretic approaches frame and answer questions about deliberation and articulate an approach to a deliberative democratic theory that builds on the strengths of both of these theoretic traditions, properly informed by empirical scholarship.     

The prevalence of drugs in injured drivers

In mid 2009 Victoria introduced compulsory drug testing of blood taken from all injured drivers taken to hospital. Δ(9)-Tetrahydrocannabinol (THC), methylamphetamine (MA) and 3,4-methylenedioxy-methylamphetamine (MDMA) are prohibited and if drivers are positive to any amount an automatic penalty is enforced. Laboratory screens were conducted on preserved blood using ELISA testing for cannabis metabolite and methylamphetamines and a fully validated LC-MS/MS method for 105 drugs including THC, amphetamines, opioids, benzodiazepines, antidepressants and antipsychotics and a number of other psychoactive substances using a minimum of two transitions per drug. Conventional GC-testing for ethanol was used to screen and quantify the presence of alcohol. 1714 drivers were tested and showed alcohol in 29% (≥ 0.01 g/100mL) and drugs in 35%. The positive rate for the three drugs prohibited by legislation was 12.5%. The prevalence of THC, MA and MDMA was 9.8%, 3.1%, and 0.8%, respectively. The range of THC concentrations in blood was 2-42 ng/mL (median 7) of which 70% had a concentration of 10 ng/mL or higher. The range of concentrations for MA and MDMA was 0.02-0.4 and 0.03-0.3mg/L (median for both drugs was 0.05 mg/L). Drugs of any type were detected in 35% of cases. The other drugs were largely prescribed drugs such as the antidepressants (9.3%) and benzodiazepines (8.9%). Neither 6-acetylmorphine nor cocaine (or benzoylecgonine) was detected in these cases.
