Angle grinders are one of the most dangerous and frequently used tools in industrial settings. Angle grinder injuries range from superficial cuts to deep penetrating injuries with underlying fracture-dislocation and vascular trauma. The injuries caused by angle grinders mostly involve the head, face, or upper limbs, while the lower limb is an unusual site. The high-speed rotating disc of the angle grinders does not respect anatomical boundaries or structures; therefore, the injuries caused may be disfiguring, permanently incapacitating, or even fatal. We report a fatal case of an angle grinder injury to the lower limb. The victim sustained a sharp cut over the left thigh while woodworking in an industrial setup. The rotating disc of an angle grinder had transected the skin, subcutaneous fat and muscles, and both the femoral vessels of the left side, which led to fatal exsanguination within 10 min of the incident. 相似文献

The dual processes of rapidly transforming cities and administrative decentralisation demands that local government address human mobility as a means of countering urban poverty. Despite this imperative, local authorities are often poorly equipped to address the needs of poor and transient residents. Through an examination of four South African municipalities, this article helps to identify three critical factors working against effective responses: poor data and conceptual bias; institutional ambiguities and budgeting processes; and, ironically, participatory planning. Although any one of these could serve as a basis for an article, by taking them together, we better summarise the challenges' scope and outline areas for further research and policy intervention. The article concludes by considering these findings' practical and scholarly implications. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

South Africa's political liberalisation and strengthening regional ties have engendered new patterns of immigration and urbanisation, resulting in South African migrants and non-nationals converging on the streets of previously ‘forbidden’ cities. Conflicts over space, services and livelihoods are emerging as these groups meet and compete. To settle these disputes, South African citizens and politicians regularly rely on nativist discourses that make one's rights to the city contingent on one's national origins. Efforts to exclude foreigners are in turn encouraging and legitimising new forms of bias, administrative discrimination and anti-foreigner policing. Bolstered by official sanction, these are creating urban ‘zones of exception’, areas in which the state authorises its agents to work outside the law. Although popular among South Africans, the extra-legal harassment, detention and deportation of non-nationals has helped entrench new economies of corruption and violence that jeopardise the rights and welfare of all urban residents. While rooted in the dynamics of post-apartheid South Africa, these findings resonate with global trends in which quests to assert sovereignty through immigration controls are resulting in actions that undermine the legitimacy and founding principles of the liberal states that undertake them. 相似文献

Homicide by stab wound is common worldwide. However, the use of unusual edged weapons is rarely reported in the forensic literature. Here, we report two cases of homicide involving a Japanese sword, or katana, and a sickle. Both of these weapons can create either stab or incised wounds with some particularities. In our cases, characteristics of the external wounds, internal injuries, and the depth of penetration raised the possibility of an unusual weapon. Meticulous forensic examination of these injuries (morphological characteristics, depth of penetration, trajectories, and cut marks in the bone) may allow the forensic expert to determine the type of weapon used. 相似文献

Testing for drugs in hair raises several difficulties. Among them is the interpretation of the final concentration(s). In a post‐mortem case, analyses revealed the presence of furosemide (12 ng/mL) in femoral blood, although it was not part of the victim's treatment. The prosecutor requested our laboratory to undertake an additional analysis in hair to obtain information about the use of furosemide. A specific method was therefore developed and validated to identify and quantify furosemide in hair by UHPLC‐MS/MS. After decontamination of 30 mg of hair, incubation in acidic condition, extraction with ethyl acetate, the samples were analyzed by UHPLC‐MS/MS. Furosemide was found in the victim's hair at 225 pg/mg. However, it was not possible to interpret this concentration due to the absence of data in the literature. Therefore, the authors performed a controlled study in two parts. In order to establish the basis of interpretation, several volunteers were tested (four after a single 20 mg administration and twenty‐four under daily treatment). The first part indicated that a single dose is not detectable in hair using our method. The second part demonstrated concentrations ranging from 5 to 1110 pg/mg with no correlation between dosage and hair concentrations. The decedent's hair result was interpreted as repeated exposures. In the case of furosemide analysis, hair can provide information about its presence but cannot give information about dosage or frequency of use. 相似文献

This paper presents a reanalysis of the Ahamad case study of 18 types of offenses. The suggested method is a nonmetric multidimensional scaling type called smallest-space analysis (SSA-I) which uncovers findings that were not expressed explicitly by the principal-components method used by Ahamad. 相似文献

This study investigated all (76) cases of intimate femicide (the killing of women by their intimate male partners) in Israel during the years 1990–1995. The analysis focused on temporal patterns, the representation of various population groups, and given motives. The findings show a relationship between the incidence of intimate femicide and a number of major events/processes experienced by Israeli society during the period investigated. Following the Persian Gulf War (in 1991), during which families were enclosed for lengthy periods in sealed rooms, there was a sharp increase in intimate femicide. On the other hand, the enactment of the Law for the Prevention of Family Violence in 1991 was followed by a sharp (though temporary) decrease in intimate femicide in 1992. New immigrants from the former Soviet Union and even more so, from Ethiopia were over-represented among intimate femicide offenders. In most cases, more than one motive is given for the intimate femicide, with 'possessiveness' being mentioned in the majority of cases usually in conjunction with other motives (such as argument/conflict between the parties, mental, drinking or drug problems of the offender). Here too, differences were found between the various population groups. The findings are discussed within the framework of a stress-support theoretical model which postulates that violence in society will be positively related to stress factors and negatively related to support systems. 相似文献

This study investigated the relationship between the subjective perception of stress and support in the population (as independent
variables) and the prevalence of homicide, robbery, and property offenses in society, while controlling for the effect of
gender, i.e., how these crimes are related to the differential perception of stress and support among males and females. The
theoretical framework is provided by a stress-support model which postulates that crime in society will be positively related
to stress factors and negatively related to support systems. Eight stress indicators and four support (solidarity) indicators
were included. The data regarding these indicators were derived from continuing surveys of representative samples of the urban
population in Israel during the years 1967–1979. The theoretical model was supported by the findings, especially those relating
to property offenses. The effects of the female indicators were strongest (and greater than those of males) with regard to
property offenses. The regression coefficients of the female indicators were also consistently larger than those of males,
indicating that women's perceptions of stress are better predictors of crime rates than those of males. The results are compared
to those of previous studies and suggestions are made for future studies in this new line of criminological research. 相似文献
