The diagnosis of diffuse axonal injury in routine autopsy practice

A 40-year-old pedestrian was involved in a road traffic accident. He lost consciousness immediately and remained comatose for 6 months until he died of a bronchopneumonia. Examination of the fixed brain revealed the late results of diffuse axonal injury. Not all the features were readily visible macroscopically, but required a limited number of histological sections from readily predictable sites for demonstration. Special stains played only a confirmatory role. This case illustrates some of the problems in diagnosing one of the commoner patterns of brain damage in head injury, and shows how the problem may best be approached in practice.     

Background survey of polyethylene in the Australian Capital Territory – A demonstration of variability in isotopic abundance values and their application to forensic casework

Plastics including adhesive tapes, cable ties, and packaging are common evidence types encountered in forensic investigations and casework. Traditional examination techniques such as Fourier Transform Infrared (FTIR) spectroscopy lack specificity and are unable to discern differences within the same polymer structures leaving the analyst with a generic identification. High quality manufacturing methods further amplify the limitations in detecting variability between samples. Isotope Ratio Mass Spectrometry (IRMS) has been shown to be a valuable technique in further discriminating plastics. Discrimination is achieved by analysing the relative abundances of stable isotopes within a sample, with differences detected in isotope ratios possibly attributed to the source of raw materials and fractionation during the manufacturing process. A survey of cling wraps and re-sealable zipper storage bags collected in the Australian Capital Territory was undertaken to assess the variability in carbon and hydrogen isotope ratios of different brands and samples. The results of this research are discussed, particularly with respect to within and between brand trends, and a case study is presented as an example of the value of including IRMS in a casework context.     

AFGHANISTAN: CROSSROADS OF THE ANCIENT WORLD (EXHIBITION ARTICLE)

A curtain-raiser by the curator of the Exhibition of Antiquities from Afghanistan, which opens at the British Museum on 3 March 2011. The exhibits come from the National Museum in Kabul and show the richness and extent of trade in ancient times through and with Afghanistan. They are from excavations at a number of sites, including Begram, Tilla Tepe and Ai Khanum.     

Power,Politics, and Primitivism: West Papua's Struggle for Self-Determination

The Bush administration answered the terror attacks of September 11, 2001, with what it called the “global war on terror,” first the assault on and invasion of Afghanistan and then the invasion and occupation of Iraq. More and more Americans joined the opposition to the Iraq war, but for some, Afghanistan remained “the good war.” But was the war on Afghanistan ever a “good war”? The authors of Ending the US War in Afghanistan (Olive Branch Press, 2010) address these and other frequently raised questions in an easy-to-read style. The chapter reproduced here, “The War in Afghanistan Goes Global,” is one of six chapters in the pocket-sized book. Other chapters are “The USWar in Afghanistan,” “The US Invasion of Afghanistan,” “The US and Other Players in Afghanistan,” “The Impact of theWar,” and “Ending the War.”
