欧洲迎来了历史上前所未有的和平统一的机会,欧元的成功已进一步地把欧洲的经济融合到一起。政治上,欧盟宪法的起草也给人们以巨大的希望,人们希望看到一个统一、和平的欧洲出现。但在2005年,法国和荷兰先后在全民公决中,否定了《欧盟宪法》,这给欧洲统一的进程蒙上了阴影。本文尝试分析此次危机出现的原因,并进一步探讨危机出现可能带来的影响,以及预测今后欧洲一体化的前景。  相似文献

Die jüngere Forschung zum sozialen Handeln von Muslimen in westeuropäischen Einwanderungsländern hebt häufig die reflexive Individualisierung von Lebensformen und religiösen Gesinnungen vor allem junger Muslime hervor. Der folgende Beitrag hinterfragt die diesem Ansatz zugrunde liegende Annahme eines Wertekanons ziviler europäischer Gesellschaften und Öffentlichkeiten, in die sich in Europa sozialisierte junge Muslime vermeintlich einfügen und muslimische Identitäten ?europäisch“ rekonstruieren. Dieser Transformationsprozess wird in diesen Theorien sowohl im Hinblick auf die familiale Lebenswelt wie im Hinblick auf die öffentliche Sphäre, in denen Muslime agieren, unterschätzt. Im Rückgriff auf Ansätze der historisch-vergleichenden Soziologie und der Religionsanthropologie erarbeitet der Aufsatz zunächst einen Begriff von ?Tradition“, der die Konstituierung, Verwaltung und Transformation von religiösen Diskursen, Praxen und Subjekten diachronisch und transgenerationell erklärt und der Gleichzeitigkeit von sozialer Einbettung und diskursiver Autonomie von Tradition Rechnung trägt. Wir zeigen, dass die sozialen Praktiken von Muslimen in Europa eine Transformation erfahren, die ihre besondere Grundlage im muslimischen Reformdiskurs im kolonialen und postkolonialen Kontext mehrerer Zentren der islamischen Welt hat. Der Fall junger Kopftuch tragender Musliminnen in Deutschland und Frankreich, die der zweiten und dritten Migrantengeneration angehören, zeigt schließlich weder eine selbst-reflexive Identitätssuche noch das ?coming out“ der Heldinnen einer nicht-westlichen Modernität, sondern ein praxisorientiertes und wissensgestütztes Räsonieren der jungen Frauen über die Wiedereinbettung des Traditionsdiskurses in die sozialen Felder (Familie, Studium, Arbeit und islamische Vereine), in denen sie operieren. Ihr Streben, das von der Traditionsdynamik der Kohärenzsuche geleitet wird, konfiguriert eine ?Alltagspolitik“, in der die Frauen ihre islamisch inspirierten Lebensprojekte gleichzeitig von moralisch erstarrten familiären ?Lebenswelten“ und von normativ erstarrten politischen Öffentlichkeiten abkoppeln und kultivieren.  相似文献

A qualitative and quantitative analytical method was developed and validated for the determination of 49 licit and illicit drugs in oral fluid. Small oral fluid samples, volume 1mL, were collected from volunteers using a modified Omni-Sal device and the analytes were extracted from an oral fluid/buffer mixture using a single Bond Elut Certify solid phase extraction cartridge. Liquid chromatography-tandem mass spectrometry (LC-MS-MS) and gas chromatography-repetitive full scan mass spectrometry (GC-MS) were used in parallel to analyze the extracts for the targeted drugs. Extracts were analyzed by GC-MS in their underivatized form and as their pentafluoropropionyl derivatives. Deuterated internal standards were used for quantification of drugs of abuse by LC-MS-MS to minimize matrix effects. Methadone-d(9) and tumoxetine were used as the internal standards for quantification of non-derivatized and derivatized analytes respectively by GC-MS. Linearity was demonstrated over the range 5-200 ng/mL and limits of detection were less than 4 ng/mL for each drug analyzed. The method demonstrated acceptable recoveries for most of the analytes and good intra- and inter-day precision. Acquisition of data by repetitive full scan GC-MS allows the addition of further analytes to the target menu.  相似文献

Eight Y chromosome short tandem repeat (STR) polymorphisms (DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, and DYS393) were analyzed in the sample of 117 unrelated Albanian males living in Kosovo. A general STR allelic frequency pattern in the Albanian population from Kosovo corresponds to other European populations. Fourty six haplotypes were observed in single copy. The most frequent haplotypes were (DYS19-DYS385-DYS389I-DYS389II-DYS390-DYS391-DYS392-DYS393) 14-11/11-13-29-24-11-13-13 (10.26%), 14-14/17-12-28-24-10-11-12 (9.40%), 13-16/18-13-30-24-10-11-13 (9.40%), and 14-17/17-13-31-24-10-11-13 (9.40%).  相似文献

The captive bolt pistol is an atypical firearm exclusively produced and used for butchery of breeding animals, but in some rare cases, it has been used as a lethal weapon for committing suicide by butchers, breeders and other people who have access to such weapons during their professional activities. This study describes the suicide committed by a butcher in the province of Udine (N. Italy) in 2001 who shot himself with his own captive bolt pistol that produced in the right temporal region a circular wound and a bone lesion of the temporal squama with a groove involving the frontal lobe; he died five days later of the fatal consequences of the meningo-encephalic lesions. The medico-legal issues implicated in this case, seen in the light of the data reported in the international literature, illustrate the difficulties faced when diagnosing these types of lesions, bearing in mind their rarity and peculiar nature, and introduce elements of differential diagnosis regarding lesions produced by similar weapons that lead to ascertainment of the event as accidental, suicidal, or homicidal.  相似文献

We demonstrate here the successful use of laser capture microdissection (LCM) and DNA fingerprinting in the identification of a case of gastric bioptic specimen mix-up. A 70-year-old man, suffering from chronic atrophic gastritis, underwent to a gastric biopsy and received a diagnosis of gastric cancer. In the absence of any clinical evidence of gastric cancer, a specimen mix-up was suspected. LCM was used to retrieve gastric cells from the histologic slide, classified as gastric carcinoma, and suspected to be mislabelled. DNA was extracted from microdissected cells, and a total of 16 different genetic loci were analyzed, using an identity test. Comparison of the results with those obtained using DNA extracted from a control slide, and from patient's saliva, demonstrated a distinct DNA fingerprint pattern in all genetic markers examined, clearly indicating the occurrence of a specimen mix-up. The combined use of LCM and DNA fingerprinting represents the most accurate and sophisticated method available for the identification of specimen mix-up, especially when only the tissue on the suspected slide is available.  相似文献

The learning objectives of this paper are to study the actual extent of medical malpractice, the medical acts at risk, and their impact on mortality. The number of suits filed against physicians for deaths resulting from alleged malpractice and autopsies ordered by the Judicial Authority in cases of possible therapeutic misadventures are rising. A major factor pushing this trend is public mistrust of healthcare providers and public and facilities. This mistrust is partly fueled by the mass media which, often to gain larger audience shares, sensationalizes single cases of real or alleged iatrogenic injury. Further, the potential for astronomic settlements, either from the single doctor or from the healthcare institution, has increased the number of legal proceedings that start on the basis of mere suspicion. In this context, the autopsy becomes an important instrument for shedding light on the situation, and it must be carried out by highly qualified and experienced professionals capable of ascertaining the cause of death, identifying any possible misconduct, and assessing its consequences. We reviewed the data regarding autopsies performed at the Forensic Medicine Section of the Department of Internal and Public Medicine of the University of Bari over 1991 to 2000. We culled the cases alleged malpractice and, from these, identified those in which the death had truly been caused by medical error. This study also allowed us to understand the incidence of lethal therapeutic misadventures and to identify the medical and surgical branches more frequently involved.  相似文献
