A study to narrow down the time when a hyoid bone fracture was sustained

An unstable hyoid bone that can be loosely moved during autopsy is initial reason to suspect trauma to the neck. The question to be answered is whether the increased mobility is due to incomplete ossification of the hyoid, a postmortem injury (damage), or an ante-mortem injury, possibly related to the cause of death. This is the first study to systematically assess whether stereomicroscopic examinations and flat-panel CT-scans of isolated, unstable hyoid bones can add information to the macroscopic examination by helping to determine when the instability arose. Sixteen isolated hyoid bones (8 female, 8 male; 4-87 years-old) were examined after being macerated. Four of the hyoid bones were already classified as unstable during autopsy. Of the other 12, 7 were fractured immediately after autopsy before being macerated, and 5 were fractured after being macerated. There were, in total, six different diagnostic constellations. Stereo-microscopic examination did not yield additional information compared with the macroscopic examination. Flat-panel CT allowed distinction between an incomplete ossification of the hyoid and a fracture, but did not help in determining whether the fracture had been sustained peri- or postmortem.     

Ossification Degrees of Cranial Sutures Determined with Flat‐Panel Computed Tomography: Narrowing the Age Estimate with Extrema

Abstract: Since Broca’s time (1824–1880), ossification of the neurocranial sutures has been used as a characteristic of age. Current approaches include the visual macroscopic examination of ecto and endocranial sutures. The evaluation of the cross‐section of sutures usually necessitates the destruction of the neurocranium. In a nondestructive alternative approach that was tested within the context of the “Digital Forensic Osteology” project that ran in cooperation with the Virtopsy^®‐Project, it emerged that the resolution of conventional multi‐slice computed tomography data sets was not high enough to image sutures. Thus for the experiments presented here, the eXplore Locus Ultra flat‐panel computed tomography scanner from GE Healthcare was used. Calottes were scanned during autopsy and then immediately returned to the corpse. So far, the skullcaps of 221 individuals have been scanned. The cross‐sections of 14 suture segments could be assessed for seven previously defined stages of ossification. In a converse step, the 14 highest and lowest age estimate values corresponding to the individual stages of suture closure found were estimated for each calotte. The obtained ranges narrowing down the age estimate were evaluated with statistics. A mean value of 43.31 years for the range of narrowed age estimates shows that this method can be a useful aid in estimating age. The results of intra‐ and inter‐observer tests showed good overall agreement between the findings of three observers. This method is suitable for a nondestructive age estimation and can be used for the entire calotte.     

Validation of Ultrastructural Analysis of Mitochondrial Deposits in Cardiomyocytes as a Method of Detecting Early Acute Myocardial Infarction in Humans*

Abstract: In the present study, ultrastructural analysis of mitochondrial deposits (black dots within mitochondria) as a method for the detection of early acute myocardial infarction (AMI) was evaluated. In 24 patients with AMI and six controls, analysis was performed in the heart of infarcted patients and noninfarcted controls. In the infarction area in lactate dehydrogenase (LDH)‐diagnosed AMI, the percentage of positive mitochondria was significantly higher compared to corresponding heart tissue in control patients and compared to noninfarcted areas within these patients. Also in patients with a clinically diagnosed AMI but no LDH decoloration, a significant higher percentage of positive mitochondria was found in the left ventricle compared to controls and noninfarcted areas. In patients with AMI, an increase in mitochondria with deposits was found in the infarction area compared to controls and noninfarcted tissue within the same patient, suggesting that electron microscopical changes in mitochondria can be used for the diagnosis of AMI less than 3 h old.     

The organizational structure of international drug smuggling

While most group offending is not well organized, it is generally assumed that high levels of organization can be found in group offending that generates revenue, such as white-collar crime, drug sales, and smuggling drugs or humans. The organizational structure of international drug smuggling has typically been viewed as highly rational and formally structured. Employing interviews with thirty-four federal prisoners convicted of smuggling large volumes of cocaine into the United States, this study explored the organizational structure of high level international drug smuggling. The subjects described a general lack of formal structure and depicted the drug smuggling operations as composed of isolated work groups without formal connections among each other. These findings bring into question the idea that these groups are rationally organized around pursuing efficiency and support recent research that suggests network security or minimizing risk are key organizing principles of drug trading organizations.     

Between the ‘Home’ and ‘Institutional’ Worlds: Tensions and Contradictions in the Practice of House Arrest

In this paper we argue that the theoretical work of Goffman (1961) on “total institutions,” Foucault’s (1977) insights into the workings of disciplinary power, and an account of contemporary forms of punishment and social control in postmodern society (Staples 2000) help us better understand the experiences of those individuals sentenced to house arrest. Based on face-to-face interviews with twenty-three people being electronically monitored in a Midwestern metropolitan area, our analysis identifies three themes that illustrate the ways in which electronic monitoring is experienced as a complex amalgam of what Goffman (1961, p. 13) saw as the distinct “home world” and the “institutional world”. These themes include (1) “Home is Where the Machine Is,” (2) “Producing Docile Bodies,” and (3) “Threat of Sanctions”. We reassert our claim (Staples 1994, 2000) that contemporary forms of social control such as electronic monitoring reflect an ongoing struggle to deal with problems and issues set in motion with the birth of modernity.     

Earth system governance: a research framework

The Earth System Science Partnership, which unites all major global change research programmes, declared in 2001 an urgent need to develop “strategies for Earth System management”. Yet what such strategies might be, how they could be developed, and how effective, efficient and equitable such strategies would be, remains unspecified. It is apparent that the institutions, organizations and mechanisms by which humans currently govern their relationship with the natural environment and global biochemical systems are not only insufficient—they are also poorly understood. This article presents the science programme of the Earth System Governance Project, a new 10-year global research effort endorsed by the International Human Dimensions Programme on Global Environmental Change (IHDP). It outlines the concept of earth system governance as a challenge for the social sciences, and it elaborates on the interlinked analytical problems and research questions of earth system governance as an object of study. These analytical problems concern the overall architecture of earth system governance, agency beyond the state and of the state, the adaptiveness of governance mechanisms and processes as well as their accountability and legitimacy, and modes of allocation and access in earth system governance. The article also outlines four crosscutting research themes that are crucial for the study of each analytical problem as well as for the integrated understanding of earth system governance: the role of power, knowledge, norms and scale.     

Comments on Andre Gunder Frank's “The centrality of central Asia”

Abstract

To the cultural geographer specializing in Central Asia, Frank's survey of the historical place of Central Asia in the world system is highly suggestive. It needs only a few clarifications, perhaps, before we address the level of historical relevance of such an area.
