Pathologic features of fatal shark attacks

To examine the pattern of injuries in cases of fatal shark attack in South Australian waters, the authors examined the files of their institution for all cases of shark attack in which full autopsies had been performed over the past 25 years, from 1974 to 1998. Of the seven deaths attributed to shark attack during this period, full autopsies were performed in only two cases. In the remaining five cases, bodies either had not been found or were incomplete. Case 1 was a 27-year-old male surfer who had been attacked by a shark. At autopsy, the main areas of injury involved the right thigh, which displayed characteristic teeth marks, extensive soft tissue damage, and incision of the femoral artery. There were also incised wounds of the right wrist. Bony injury was minimal, and no shark teeth were recovered. Case 2 was a 26-year-old male diver who had been attacked by a shark. At autopsy, the main areas of injury involved the left thigh and lower leg, which displayed characteristic teeth marks, extensive soft tissue damage, and incised wounds of the femoral artery and vein. There was also soft tissue trauma to the left wrist, with transection of the radial artery and vein. Bony injury was minimal, and no shark teeth were recovered. In both cases, death resulted from exsanguination following a similar pattern of soft tissue and vascular damage to a leg and arm. This type of injury is in keeping with predator attack from underneath or behind, with the most severe injuries involving one leg. Less severe injuries to the arms may have occurred during the ensuing struggle. Reconstruction of the damaged limb in case 2 by sewing together skin, soft tissue, and muscle bundles not only revealed that no soft tissue was missing but also gave a clearer picture of the pattern of teeth marks, direction of the attack, and species of predator.     

NOT JUST BRICKS AND MORTAR: EEO IN HOMESWEST

Abstract: Moves by both state and federal governments to implement private sector management practices in government administration have received attention from a number of writers. Feminist critics of corporate management argue that, in very devolved situations, public sector management concentrates on the achievement of program outcomes to the detriment of other management objectives and Equal Employment Opportunity is ignored. The contention that efficiency and effectiveness are promoted at the expense of equity under a regime of public sector corporate management will be addressed through a case study of the West Australian Housing Commission, Homeswest. This paper examines the results of Equal Employment Opportunity programs in a highly corporatised state government agency.     

A Study of the Presence of Gunshot Residue in Pittsburgh Police Stations using SEM/EDS and LC‐MS/MS

Due to possible secondary transfer of gunshot residue (GSR) onto a suspect in police custody prior to sampling, a baseline must be created for the amount of GSR present. With an increase of “lead free” ammunition, testing for both gunpowder and primer GSR is relevant. Seventy samples were collected using carbon‐coated adhesive stubs from four Pittsburgh Police Stations and vehicles to investigate these locations as sources of secondary GSR contamination. These seventy samples were analyzed for primer GSR using scanning electron microscopy‐energy‐dispersive X‐ray spectrometry. One primer GSR particle was detected; no sample was classified as positive for primer GSR. These same samples were then analyzed for gunpowder GSR using liquid chromatography coupled to tandem mass spectrometry to test for akardite II, ethylcentralite, diphenylamine, N‐nitrosodiphenylamine, 2‐nitrodiphenylamine, and 4‐nitrodiphenylamine. Ethylcentralite was quantifiable in two test samples. These results suggest there is a negligible potential for secondary transfer of primer and gunpowder GSR.     

A Retrospective Study of the Investigation of Homicidal Childhood Asphyxial Deaths

As one of the leading causes of traumatic deaths in newborns, infants, and young children, there is no anatomic or microscopic feature that is pathognomonic for asphyxial deaths. Instead, pathologists rely on investigation information, including confessions and/or witness statements, and potential evidence at the scene. Twenty cases of homicidal newborn, infant, and young children asphyxial deaths were reviewed, which included death and police investigation reports and autopsy reports, as well as histology slides of lung sections. This series of homicidal asphyxial deaths highlight that, in a vast majority of such cases, the final cause and manner of death rulings are dependent on confession by the perpetrator. Furthermore, this series highlights the possible role of histology to help forensic pathologists better certify asphyxial deaths. Finally, this series emphasizes important investigation points and considerations at autopsy during the investigation of asphyxial deaths in newborns, infants, and young children.     

Decomposing firm-level productivity growth and assessing its determinants: evidence from the Americas

This paper provides novel empirical evidence on productivity growth in the manufacturing sector in Chile, Colombia, Mexico and Peru. Relying on plant-level data, we first decompose productivity and productivity growth into plant-level growth and market allocation forces. While the average productivity of the survivors is higher than the overall contribution of reallocation forces, during recessions the inverse is true and reallocation gives a positive, albeit small, contribution to aggregate productivity growth. Next we analyze how policy measures can determine allocative efficiency levels and growth, and find important scope for action on education, financial regulation, and structural reforms.     

Characterisation of forward stutter in the AmpFlSTR® SGM Plus® PCR

PCR amplification of tetrameric short tandem repeats (STRs) can lead to Taq enzyme slippage and artefact products typically one repeat unit less in size than the parent STR. These back stutter or n ? 4 amplification products are low-level relative to the amplification of the parent STR but are widely seen in the forensic community where tetrameric STRs are employed in the generation of DNA profiles. To aid the interpretation of DNA mixtures where minor contributor(s) might be present in comparable amounts to the back stutter products, the typical amounts of back stutter generated have been well characterised and guidelines for interpretation are in place. However, further artefacts thought to be Taq enzyme slippage leading to products with one repeat unit greater than the parent sequence (n + 4 or forward stutter) or two repeats less (n ? 8 or double back stutter) also occur, but these have not been well characterised despite their potential influence in mixture interpretations. Here we present findings with respect to these additional artefacts from a study of 10,000 alleles and include guidelines for interpretation.     

The Public Participation Act: A Comprehensive Model Approach to End Strategic Lawsuits Against Public Participation in the USA

Commentators have documented the disturbing use of the courtroom to silence those who speak out on important issues. Too often, parties resort to meritless lawsuits in response to another's free expression or communication with the government. These lawsuits are called SLAPPs, or Strategic Lawsuits Against Public Participation. In the USA, they have emerged as a significant threat to the rights of expression and petition guaranteed in the First Amendment to the US Constitution. A majority of the US States have passed 'anti-SLAPP laws', but there is no uniform protection. The model legislation outlined in this paper is intended to guide those who seek uniform, comprehensive protection against SLAPPs.     

Navigating tensions in co‐production: A missing link in leadership for public value

New forms of public leadership are needed to design and implement co‐production of public value. We draw on narrative analysis to explore the barriers to developing the capacity for co‐production of public value in disadvantaged and vulnerable Indigenous communities and find that existing norms not only crowd out efforts at reform, but can work against them. In particular, we find that upward accountability and a focus on expert knowledge are the most problematic for co‐production of public value. We focus on how more traditional practices of public administration mediated the achievements of public leaders in their co‐production efforts when Australian governments introduced strategies for partnership with Indigenous communities for services design and delivery. The analysis suggests that creating a broader enabling environment of supportive logics would allow public leaders to engage more productively with inherent tensions between old and new ways of working.
