We investigate the effect of social capital on hygiene practices pertaining to lives of the extreme poor in rural Bangladesh. Analysing a unique survey dataset for 5,600 extreme poor households, we document a significant positive effect of social capital on sanitary latrine use and wearing shoes/sandals at home for hygiene. We account for the endogeneity of social capital by instrumental variable estimation. Our findings emphasise the role of social capital in preventing common diseases through improving hygiene practices for the extreme poor, who usually lack access to medical services in the event of illness, which has important policy implications.  相似文献

This article interrogates emerging trends and patterns in the process of radicalisation and violent extremism in West Africa and the implications for regional and international security regimes, practices and thinking. It argues that there are real and imagined challenges of radicalisation and violent extremism. The overarching view is that the emergence of intra- and extra-African preoccupation with violent extremism alone, rather than alongside seriously addressing its structural undercurrents related to preventing and interrupting the process of radicalisation, distorts the security realities and further exacerbates the security situation in Africa. Radicalisation and violent extremism further integrates West Africa into global security assemblages, yet the absence or non-incorporation of an indigenous African (civil society) perspective or counter-narrative about radicalisation and violent extremism uncritically fuses and conflates the strategic interests of major powers with the local realities in Africa. Moreover, there is a huge potential that national governments could exploit local, regional and international interests in counteracting terrorism for domestic political advantages, such as mis-characterisation of subsisting conflicts, regular political opposition and other local grievances as cases of terrorism, thereby risking a deterioration in security conditions.  相似文献

<正> 财产所有权简称所有权。其客体问题是所有权理论中的一个基本问题。所有权的客体是否应该限于有形财产,这是当前需要重新探讨的一个重大问题。它直接关系到能否正确认识在建立现代企业制度过程中迫切需要解决的公司财产权和股东财产权的性质问题。笔者就此发表一些新的、不成熟的见解,欢迎批评、指正。  相似文献

The aim of this study is to investigate the mechanism of injury of abducens nerve at petroclival region in severe head trauma. Twenty specimens provided from 10 autopsied cases due to severe head trauma were investigated macroscopically and histopathogically. The slices of the abducens nerve taken consecutively along its course at petroclival region were stained with Hematoxylline-Eosin and evaluated under light microscope. In addition, coexisting cervical injuries in these cases were assessed macroscopically. Edema and perineural hemorrhagia of abducens nerve were identified in all cases. Nerve injury was found more exaggerated at the sites of dural entry point and petrous apex than any other parts of the abducens nerve. Furthermore, microscopically, also remarkable perineural hemorrhage of the abducens nerve was observed at the site of its anastomoses with the sympathetic plexus on the lateral wall of the internal carotid artery (ICA). Abducens nerve is injured at the sites of dural entry point, petrous apex and lateral wall of the ICA, directly proportional with the severity of the trauma. This finding is also significant in verification of the severe head trauma.  相似文献

Abstract:  A wide variety of handmade firearms have been involved in criminal cases in the city of Trabzon, Turkey. Although they are often very similar to commercially manufactured firearms in terms of design, loading and locking mechanisms, and cocking and firing arrangements, these guns are constructed from cheap materials and are not safe for firing. Handmade firearms manufactured in the Black Sea region of Turkey, particularly in the city of Trabzon, are similar to pistols manufactured by Browning, Luger, Star, Smith and Wesson, Berretta, and MAB. A total of 201 handmade guns referred to the Criminal Police Laboratories for examination from 2003 to 2005 were evaluated with respect to type, number of barrels, size and caliber, rifling, design, mechanism, operability, legality, and similarity to commercial models. We found that most of these handmade guns resembled commercial models in several aspects.  相似文献

Das deutsche “Gesetz über das Inverkehrbringen, die Rücknahme und die umweltvertr?gliche Entsorgung von Elektro- und Elektronikger?ten” (ElektroG) ist eines der auf europ?ischen Vorgaben beruhenden Rechtsinstrumente zur Vermeidung und Entsorgung von Abf?llen. In letzter Zeit sind hierzu eine Reihe von h?hergerichtlichen Urteilen ergangen, so dass bisher bestehende Unsicherheiten über die Reichweite der Registrierungspflicht beseitigt, sowie mehr Klarheit bei der Gruppenfinanzierungsverantwortlichkeit geschaffen wurde.  相似文献

An expert examination is a medical examination performed by a doctor on the order of a police officer or investigating judge. It includes a clinical examination of the subject, collection of samples for toxicological analysis, and the doctor's assessment of whether the subject is under the influence of psychoactive substances. The doctor requires expert knowledge, skill, experience and sufficient time to successfully perform the examination. Since the accurate assessment of the effects of psychoactive substances present depends on a comprehensive evaluation of toxicological test results, the calculation of results at the time of the event and the results of the medical examination, an unprofessionally performed examination can have far-reaching consequences, primarily legal in nature.  相似文献

During executing some activities by the police, a mummified human fetus was accidentally revealed on a scrap of paper. It came from pregnancy considerably not carried to term, lasting about 2.5 lunar months. Medical examination did not give evidence of mechanical manipulation such as abortion or disintegration. The aim of the study was the genetic identification of the mummified fetus and an answer to the question if an indicated supposed mother was the mother of the fetus. In the study a relevant factor was maternity confirmation by means of statistic calculations.  相似文献

The authors describe a rare case of lethal methadone intoxication of a 3-week-old infant. Born of a drug-addicted mother who was undergoing methadone substitution therapy, the newborn presented withdrawal symptoms and was immediately admitted to a paediatric ward where it was treated for 3 weeks, without administration of methadone. The infant died during bottle feeding within 24 h following discharge home.A post-mortem examination was performed as well as histopathological, toxicological and genetic tests were carried out in order to establish the cause and mode of death.The autopsy revealed obstruction of the lower air passages by stomach contents along with classical features of asphyxia. Toxicological tests revealed high concentrations of methadone and its metabolite in blood and urine as well as presence of methadone in stomach contents, and the DNA polymorphism analysis of the (sex-specific) amelogenin locus gave a negative result.On the basis of the results of the post-mortem examination, the laboratory tests and the police investigation, it was concluded that the drug was ingested with the bottle milk, and the possibility of administration of methadone at the hospital or its ingestion with the breast milk was precluded. Though both the cause and mode of death were established, the public prosecutor discontinued proceedings in the case due to inability to find the perpetrator.  相似文献
