Abstract: The growth in popularity of flying ultralight aircraft and paragliding has been associated with an increased involvement of Emergency Medical Services because of various types of trauma suffered from both inexperienced and skilled individuals. This case presentation reports on a paraglider pilot, who was seen spinning “unusually” rapidly toward the ground, without visible attempts to regain control of the aircraft. Besides the bilateral mydriasis and the absence of any ECG activity, there was a significant swelling of face, lips, neck, and tongue. Upon opening the mouth, a dead bee was found over the tongue, underneath the palate. A fatal anaphylactic shock was the likely cause of death of the pilot while still “in mid‐air.” This case is certainly different from the commonly reported accidents during paragliding. An updated review of the medical literature shows no reported cases of fatal anaphylactic shock during the practice of paragliding.  相似文献

The aim of this cross-sectional study was to test the accuracy of Cameriere's European formula for age assessment in a large sample of Mexican children. The accuracy of dental age estimation was defined as how closely real age, measured as the difference between chronological age (CA) and dental age (DA), could be predicted. Digitalized orthopantomographs of 502 Mexican children (254 girls and 248 boys), aged between 5 and 15 years, were analyzed. The seven left permanent mandibular teeth were evaluated using Cameriere's method. Intra- and inter-observer variability for this technique was tested on a small random sample. Dental age was estimated for each individual and compared with known chronological age. Accuracy was measured as the difference between known chronological age and dental age and tested for significance with the mean prediction error (ME). The standard deviation and 95% confidence interval of the mean difference were also calculated. ME was 0.63 years for girls and 0.52 years for boys. ME was found to be slightly overestimated by 0.10 years for girls, but was correctly estimated for boys with an accuracy of 0.00. In conclusion, this method is very useful and may be recommended for practical application both in clinical dentistry and forensic procedures on the Mexican population.  相似文献

This work attempts to understand whether it is possible to talk about the emergence of specific recurring linguistic patterns in UN resolutions, used as a political strategy. The paper presents a comparative analysis between a corpus of resolutions related to the Second Gulf War and to the 2011 North Korean nuclear crisis, focussing on ethic adjectives and preambulatory and operative phrases used in these resolutions. It is attempted to show how vague and weak expressions can be used either to lead to intentionally biased interpretations of the law as was supposed in the Iraqi case, or to mitigate international tensions, though maintaining a firm position against international threats, as supposed for North Korea.  相似文献

In Wicks v State Rail Authority (NSW) (2010) 84 ALJR 497 the High Court of Australia held that, among other things, plaintiffs (who establish that they suffer a recognised psychiatric illness as a result of the breach of duty of care owed to them by the defendant under s 32 of the Civil Liability Act 2002 (NSW)) are entitled to recover damages for pure mental harm under s 30 if their psychiatric injury arose "wholly or partly from" a "series of shocking experiences" in the form of "a sudden and disturbing impression on the mind and feelings" in connection with witnessing at the scene "another person ('the victim') being killed, injured or put in peril by the act or omission of the defendant". The High Court construed the phrase "being ... injured or put in peril" to include plaintiffs who suffer pure mental harm by witnessing at the scene another person being injured through the process of suffering pure mental harm in the form of psychiatric injury occasioned by the defendant's negligent act or omission. The Wicks decision raises the question whether the expanded liability of defendants for pure mental harm is economically sustainable.  相似文献

Previous research on the RAG color‐coded prioritization systems for the discovery of clandestine graves has not considered all the factors influencing the burial site choice within a GIS project. The goal of this technical note was to discuss a GIS‐based quantitative approach for the search of clandestine graves. The method is based on cross‐referenced RAG maps with cumulative suitability factors to host a burial, leading to the editing of different search scenarios for ground searches showing high‐(Red), medium‐(Amber), and low‐(Green) priority areas. The application of this procedure allowed several outcomes to be determined: If the concealment occurs at night, then the “search scenario without the visibility” will be the most effective one; if the concealment occurs in daylight, then the “search scenario with the DSM‐based visibility” will be most appropriate; the different search scenarios may be cross‐referenced with offender's confessions and eyewitnesses’ testimonies to verify the veracity of their statements.  相似文献

How do immigrant Mexican workers perceive the policies and social discourses that regulate their insertion into American society as noncitizens and illegals? Using ethnographic fieldwork and in-depth interviews, evidence is presented that unauthorized Mexican migrants do not consider themselves lawbreakers but rather moral actors responding to difficult socioeconomic conditions. Informed by a keen understanding of the social forces oppressing them, these migrants articulate a discourse of social justice that works as a powerful counterpoint to the hegemonic ideas of citizenship, belonging, and illegality. A careful analysis of migrant social reflexivity offers a much-needed corrective to the prevailing top-down perspective typically offered among contemporary scholars. By looking at the ways in which migrants make sense of immigration policies and articulate their right to have rights, this examination departs from the widespread tendency among scholars and policy makers of analyzing the migrant’s social and civic status as a matter of assimilation and immigration control.  相似文献
