Given that most fatal hangings are suicidal and occur in locations that have been selected to conceal this activity (thus maximizing the chances of a lethal outcome), there has been very little corroboration of the speed with which unconsciousness and death may occur. A 35-year-old male is reported who committed suicide by hanging immediately after talking to his spouse. Police investigations confirmed her reliability as a witness indicating that lethal anoxia in this case had occurred within a very short time (most likely in less than 1 min) of suspension. The speed with which death may result from hanging not only gives an insight into fatal pathophysiological mechanisms, but also provides useful information for situations where a lethal outcome is to be avoided, or is not intended. For example, individuals at risk of suicide who are being monitored in institutional facilities need to be constantly under direct visual surveillance as significant hypoxia can be rapidly induced, parents and caregivers with infants and children in potentially unsafe sleeping environments need to realize how swiftly death or irreversible anoxic brain damage may occur from neck compression, and those who engage in recreational asphyxia should be informed just how quickly a fatal outcome may ensue.  相似文献

Population differences in dental development between Black and White ethnic groups have been debated but not previously studied in the UK. Using inappropriate data for dental age estimation (DAE) could lead to erroneous results and injustice. Data were collected from dental panoramic radiographs of 5590 subjects aged 6–24 years in a teaching hospital archive. Demirjian stages were determined for left-sided teeth and third molars and data collected regarding hypodontia and third molar agenesis. Third molar development in self-assigned Black British, including other self-assigned Black ethnicity, was compared with that of self-assigned White British subjects. Data were compared for males and females in the two ethnic groups using T-tests for Demirjian Stages A–G of third molar development and Mann-Whitney tests for Stage H once a cut-off age at the maximum age for Stage G had been imposed. Third molar development occurred earlier in subjects of Black ancestry compared to those of White ancestry. While both ethnic groups showed large age ranges for every third molar stage, in female subjects these generally occurred at least 1.5 years earlier, and in males at least one year earlier. Hypodontia and third molar agenesis were more prevalent in White British, but the ethnic difference in third molar development persisted in subjects with complete dentitions. This is a large study that confirms ethnic differences in a London population, emphasises the difficulties of establishing the 18-year-old threshold using DAE, and confirms the risk of overestimating the age of individuals of Black ethnicity using White ethnic reference data.  相似文献

This study presents a set of methods based on input-output analysis to measure the size and structure of a country's information economy. Published current national data bases do not identify even the broad contours of a country's information economy. The methodology which is stylised algebraically using input-output modelling unravels the latent information economy. Both the primary or marketed information activities and the non-marketed or secondary information activities are measured. The interdependencies of the primary and secondary information sectors with the non-information sectors such as agriculture and manufacturing are examined. Linkages and multipliers are also calculated using consistent approaches. Finally, the methodology is empirically validated using Australia as a case-study and the results are discussed.  相似文献

Epidemiological combined with experiential evidence from communities can produce important and sometimes surprising insights into gender relations, to inform policies that address changing needs. CIET has standardised a community-based cross-design for the gender-sensitive collection and analysis of three types of evidence: impact, coverage, and costs. Five steps help to ensure that women's voices are heard in planning. Gender-stratified analysis of existing data is a starting point. Stratification of all responses by sex of the respondent prevents a numerical bias in favour of men translating into a gender bias in the analysis. Female focus groups inform survey design, interpretation, and appropriate strategies for change. Gender is a factor in risk and resilience analysis. Finally, gender-sensitive logistics ensure women's equal participation. First-order outputs include actionable gender data to advocate in favour of women. Second-order outputs include an enabling environment for equitable development, challenging the gendered patterns of economic marginalisation.  相似文献
