Electronic control devices (ECDs) deliver high‐voltage, low‐current energy pulses temporarily paralyzing a person. For the ECD–human interaction, we have developed a computer model using the SEMCAD program within which to simulate the electrical effects throughout the body resulting from the imposition of an ECD pulse at a particular point on the body surface. Our human body models were based on cross‐sectional MRIs and CT scans, with the dielectric properties of the various tissues assigned based on previously published values. We simulated the application of a single ECD pulse and calculated the resulting electric field strength and current and charge densities at different body locations. The results were compared with corresponding values obtained by other researchers in similar simulations. Furthermore, we simulated an application of a pulse of 20‐millisecond duration equal to the European household current of 50 Hz and to the ventricular fibrillation threshold. The resulting current level indicated at the heart muscle was 1/5 the level considered the threshold for triggering ventricular fibrillation. 相似文献

Schizophrenia is associated with a significant risk of suicide. According to recent research, 10-15 % of all schizophrenic patients die by suicide. It is not uncommon that the victims show sharp force injuries, so that the forensic pathologist first has to differentiate between self-infliction and involvement of another person. The authors' case report presents a 68-year-old schizophrenic patient who committed suicide by jumping out of a window of his apartment located on the second floor after inflicting multiple stab wounds to his thoracic region. At autopsy, an older stab wound to the apex of the heart was detected. In the criminal investigation, a suicide attempt made 13 days before could be ascertained. As the patient did not want to be taken to a hospital at that time, the injury had never been examined or documented. Since there was no evidence suggesting homicide, the older stab to the heart was interpreted as a tentative injury. 相似文献

Although the Suchey–Brooks (SB) system is currently the most widely used method for age-at-death estimation from the pubic bone, the system continues to evolve through stepwise improvements. Since the system was developed from a pubic bone sample derived mainly from North Americans, it is unclear how well it performs on populations from other continents. During the last decade, studies of the SB system on pubic bone samples from local populations in Europe and Asia have indicated regional differences in the relationship between age and pubic bone development. However, these studies have for the most part followed different research protocols, which make comparisons between their results less meaningful. It would be most useful if future regional analysis of the SB system were done in a rigorous and uniform fashion, following standard procedures. In this paper, sampling and statistical considerations are outlined that hopefully will help to standardize research on the SB system. 相似文献

Although the attitudes towards homosexuality have become more liberal especially in industrialized Western countries, there is still a huge variance in terms of the levels of homonegativity worldwide. This article seeks to explain this variance by means of a multi-level-analysis of 79 countries. The data stem from the last two waves of the World Values Survey. On the basis of this data, the article focuses on the power of the religious denomination of a person and her religiousness in order to explain her attitude towards homosexuality; for both variables a strong influence can be detected. In addition, the article indicates that, on the individual level, socio-demographic variables??e.g. age, gender, education, marital status or profession??are highly interconnected with the intensity of homonegativity. On the country-level, however, the main explanatory factors are both the economic development and the communist heritage. The article further highlights significant conditional relationships by introducing cross-level interactions and interaction terms on the individual level. The final model explains about 60% of the variance on the aggregate level and 30% on the individual level. 相似文献

In response to the recent Productivity Commission report into mental health, the previous Federal Government announced its intention to produce a new national agreement that lays the platform for Australia's sixth national mental health plan. It has been recommended mental health move to a more regional model of governance and planning, away from a centralised, top-down approach, partly in response to broader reforms affecting health care, and partly in direct response to consistent inquiry evidence that the mental health system remains in crisis. The past 30 years of mental health planning have been centralised. Successive national plans set a broad framework, with real decisions about mental health funding and service allocation made in the health departments of our capital cities. Will the next plan sponsor or inhibit regionality in mental health planning? This paper assesses Australia's historical approach to health planning particularly as it affected mental health and the costs arising. In learning these lessons, we propose the necessary ingredients to facilitate a regional, innovative, and effective approach to decentralised planning, for better mental health outcomes. We cannot afford to replicate the failed planning approaches of the past. 相似文献
