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.     

Unanswered Questions about Japan-Russia Relations in 2017

Divergent views of Japan-Russia relations in 2017 result from leaving questions unanswered. This article seeks to answer the following queries. What is the sales pitch in Japan for Abe's wooing of Putin? Why is this rationale misleading? Why is Abe keen on pursuing Putin? What motivates Putin to encourage Abe yet hold back? When did talks hit a snag? Why was 2016 different from 2001? Is the US to blame for no breakthrough? What are the cause and effect of scapegoating for no summit success? Which Japanese criticisms—by the left or the right—of the summit make a better case? Do Abe and Putin have much freedom to maneuver? Where are Japan-Russia relations now headed? Through responses to these questions, we gain an understanding of the misleading coverage of the December 15–16 Putin visit to Japan and the difficulties ahead for Abe to achieve a breakthrough in Japan-Russia relations.     

The evolution of South Africa's democracy promotion in Africa: from idealism to pragmatism

South Africa is an emerging power with fairly strong democratic institutions that were crafted during the transition from minority to majority rule twenty years ago. How has South Africa used its position and power to promote democracy in Africa? Against the backdrop of debates on democracy promotion by emerging powers, this article probes attempts by successive post-apartheid governments to promote democracy in Africa. We argue that although democracy promotion featured prominently in South Africa's policy towards Africa in the immediate post-apartheid period under Nelson Mandela, the administrations of Thabo Mbeki and Jacob Zuma faltered in advancing democratic norms. This is largely because South Africa has confronted pressures to maximize pragmatic national interests, which have compromised a democratic ethos in a continental environment where these values have yet to find steady footing.     

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.     

Posttraumatic diaphragmatic hernia and death--etiologic factor or putrefactive artifact?

Late-presenting diaphragmatic hernias, whether congenital or acquired, may remain clinically undetected until mediastinal shift with cardiorespiratory compromise or intestinal or gastric infarction with perforation occur. A right-sided diaphragmatic hernia with herniation of small intestine into the adjacent pleural cavity is described in a 72-year-old man who was found dead at home in a putrefactive state. Subsequently, a history of a motor vehicle accident 8 years previously was obtained. Although postmortem herniation due to extensive putrefactive change may have occurred, producing gaseous distention and migration of the intestine, tight twisting of the herniated intestine several times around a pleural fibrous adhesion suggested that the herniation could have been an antemortem event. Unfortunately, marked tissue autolysis prevented assessment of possible ischemic changes in the herniated intestine. Although diaphragmatic hernia may be a contributing factor to death at all ages, it may not be possible to exclude it as an artifact of putrefaction in a predisposed individual.     

An investigation into the usefulness of the MMPI and MMPI-2 in municipal and state police candidate selection

The Minnesota Multiphasic Personality Inventory (MMPI) and the later revision (MMPI-2) have been two of the most frequently employed instruments in the selection of law enforcement officers (Bartol, 1996). In this study, the following three sets of data were collected and analyzed: municipal law enforcement officer candidates tested with the MMPI, municipal law enforcement officer candidates tested with the MMPI-2, and state police trooper candidates tested with the MMPI-2. These three data sets were evaluated for their effectiveness at predicting “pass/fail” status on police candidate interview using multiple linear regression. A combination of subscales were found to be associated with classification as either pass or fail on interview.     

Social Rules: Some Problems for Hart’s Account,and an Alternative Proposal

What is a social rule? This paper first notes three important problems for H.L.A. Hart’s famous answer in the Concept of Law. An alternative account that avoids the problems is then sketched. It is less individualistic than Hart’s and related accounts. This alternative account can explain a phenomenon observed but downplayed by Hart: the parties to a social rule feel that they are in some sense ‘bound’ to conform to it.

     

In search of blood--detection of minute particles using spectroscopic methods

An examination protocol for rapid detection of remnants of blood particles on garments of suspects in bloody murder cases is described. Microparticles of blood are sampled along with fibres and hairs using the tape lifting method. The tapings are searched with a low power microscope for red particles with morphology similar to blood. Presumed blood traces are further examined using microspectrophotometry on the cut out piece of taping. The typical visible spectrum of haemoglobin is characteristic for blood. Alternatively Raman spectroscopy can be used to measure the characteristic vibrational spectrum of haemoglobin. At a later stage, these particles may be removed from the piece of taping in order to extract the blood and attempt to obtain a genetic profile.
