Asphyxial death during prone restraint revisited: a report of 21 cases

Determining the cause of death when a restrained person suddenly dies is a problem for death investigators. Twenty-one cases of death during prone restraint are reported as examples of the common elements and range of variation in these apparently asphyxial events. A reasonable diagnosis of restraint asphyxia can usually be made after ruling out other causes and collecting supportive participant and witness statements in a timely fashion. Common elements in this syndrome include prone restraint with pressure on the upper torso; handcuffing, leg restraint, or hogtying; acute psychosis and agitation, often stimulant drug induced; physical exertion and struggle; and obesity. Establishing a temporal association between the restraint and the sudden loss of consciousness/death is critical to making a correct determination of cause of death.     

Interdependence,interaction and metaphor in multisemiotic texts

Systemic frameworks for discourse analysis of visual/verbal and mathematics texts are used to examine the functionality of language? visual display and mathematical symbolism, and the meaning arising from interaction and interdependence between these semiotic codes in joint constructions. The nature of the interaction between options, classified as unmarked or marked, determines the meaning made in that instance and, more generally, provides an impetus for the expansion of the meaning potential of each semiotic. The phenomenon where semantic shifts occur when functional elements are reconstrued in another semiotic is called semiotic metaphor. Rather than the notion of an overlay of meaning typically associated with grammatical metaphor, the potential exists here for more dramatic forms of semantic shift. Examples of semiotic metaphor categorised as ‘parallel semiotic metaphor’ and ‘divergent semiotic metaphor’ are given in the text analysis.     

Age and ossification of the hyoid bone: forensic implications

Hyoid bones from a medical examiner population were visually and radiographically examined to determine the presence or absence of bony fusion of the greater cornua to the central body. Fusion was found to increase in frequency with age. Hyoid bones fused more frequently in males than in females. Females showed an especially high frequency of unilateral nonfusion.     

Analysing multimodality in an interactive digital environment: software as a meta-semiotic tool

The present paper discusses issues arising from the use of an interactive digital software tool to analyse multimodal communication. The focus is on the ways in which such technical resources and associated techniques enable the analyst of social semiosis to apply different types of analysis, and provide the site for critical reflection upon the results of such analyses. The aim is to present an argument for the use of an interactive digital software application as a meta-semiotic tool. Three major challenges for scholars engaged in multimodal social semiotics are addressed in pursuing this aim, specifically with reference to the development of digital interactive analytical resources. Firstly, scholars are faced with the task of not only accounting for an increasing range of semiotic resources, but also for the way different semiotic phenomena interact to produce meaning. Secondly, the multimodal semiotician has a broad range of analytical approaches potentially relevant to any task to draw upon. Thirdly, the nature of contemporary media forms offer challenges themselves in terms of access, analysis and presentation of analysis.     

“David Byrne really does love PowerPoint”: art as research on semiotics and semiotic technology

This article presents a reading of David Byrne's Envisioning Emotional Epistemological Information, an art work created with MicroSoft's presentation software PowerPoint, as an instance of creative research on semiotics and semiotic technology. It reveals commonalities and differences between Byrne's ideas about PowerPoint and related ideas from linguistics and semiotics, and is intended as a contribution to research on PowerPoint, and on semiotic technologies generally, as well as to efforts aimed at developing criteria for evaluating art as research on semiotics.     

Autoerotic asphyxial death following television broadcast

How individuals who engage in autoerotic asphyxial activities first become aware of its purported erotic potential is debated. The case of an adult male who died from autoerotic asphyxiation shortly after watching a television show that discussed sexual asphyxiation is reported. A request is made that medical examiners and coroners report other accidental autoerotic deaths that are temporally associated with this television broadcast.     

Democratic Transitions

Przeworski et al. (2000) challenge the key hypothesis in modernization theory: political regimes do not transition to democracy as per capita incomes rise, they argue. Rather, democratic transitions occur randomly, but once there, countries with higher levels of GDP per capita remain democratic. We retest the modernization hypothesis using new data, new techniques, and a three-way rather than dichotomous classification of regimes. Contrary to Przeworski et al. (2000) we find that the modernization hypothesis stands up well. We also find that partial democracies emerge as among the most important and least understood regime types.     

Three fatalities in flash fire with variable dental charring

The deaths of three teenagers in an automobile crash and flash fire are presented. The inability to draw valid conclusions about whether the victims were dead prior to the fire based on dental examination is discussed.     

Reenactment of circumstances in deaths related to restraint

Reenactment of the circumstances in deaths associated with restraint, utilizing participants and witnesses while memories are fresh, may help death investigators more accurately determine the cause of death. Two recent deaths in Ventura County that occurred during restraint are discussed. Within a day of the autopsies the restrainers agreed to participate in reenactments of the restraint process, utilizing live volunteers as subjects. They allowed videotaping. Deaths associated with restraint often have nonspecific autopsy findings. Timely reenactment of the circumstances of deaths associated with restraint can help death investigators more accurately determine the probable cause of death in these difficult cases.
