The eruption and mineralization of third molars are the main criteria for dental age estimation of living people involved in criminal proceedings. Since the development of third molars is usually completed by the age of 19 or 20 years, this feature cannot be used to ascertain whether a person has attained the forensically relevant age of 21 years. This study examined whether the DMFT index or the third molar DFT index could supply reliable information enabling conclusions to be drawn about whether a person has reached the age of 21. To this end, 650 conventional orthopantomograms of German subjects aged 18 to 30 years were evaluated. The DMF index variations considered were found to be unsuitable for determining whether a person is over 21 because they displayed a weak correlation with age and considerable individual scatter. A high indicative value can only be attributed to a third molar DFT index of 4, although this is rarely observed in the relevant age group. An X-ray examination of the medial clavicular epiphyseal cartilage is, therefore, strongly recommended when assessing whether a person has attained 21 years of age.  相似文献

Durch das Oderhochwasser, aber vor allem durch die Flutkatastrophe an der Elbe im August 2002, ist der Hochwasserschutz verstärkt in das öffentliche Bewusstsein getreten. Dies hat auf der Ebene von Bund und Ländern zu verschiedenen Aktionen geführt, die sich nunmehr in Gesetzesänderungen niederschlagen sollen 1. Der Hochwasserschutz kann dabei durchaus in ein Spannungsverhältnis zu anderen öffentlichen und privaten Anliegen und Belangen treten—vor allem, wenn sich aus deren Sicht Einschränkungen für die bauliche oder sonstige Nutzung der betroffenen Flächen ergeben können. Ein wichtiger Teilausschnitt aus diesem Gesamtproblem ist das Spannungsverhältnis des Hochwasserschutzes zum übrigen Fachplanungsrecht, zum Raumordnungsrecht und zur Bauleitplanung. Hierüber soll auf der Grundlage des vorliegenden Gesetzentwurfs der Bundesregierung zum verbesserten Hochwasserschutz berichtet werden. *) Der Beitrag beruht auf einem Vortrag, den der Verfasser auf dem 9. Leipziger Umweltrechts-Symposium Rechtliche Aspekte des vorbeugenden Hochwasserschutzes am 22. 4. 2004 gehalten hat und der auch in dem von dem Direktoren des Instituts für Umwelt- und Planungsrecht, Prof. Dr. Martin Oldiges und Prof. Dr. Wolfgang Köck betreuten Tagungsband erscheinen wird.  相似文献

This article gives an overview of current pharmacological treatment of paraphilias and sex offenders focusing on the situation in Germany. Information about selective serotonin reuptake inhibitors (SSRI) is followed by data about established antihormonal substances (cyproterone acetate/CPA, and medroxyprogesterone acetate/MPA), as well as a more detailed account on luteinizing hormone-releasing hormone agonists (LHRH agonists). The results of open, uncontrolled clinical studies with SSRIs (n = 16) and LHRH agonists (n = 11) in paraphilic outpatients confirm the positive effects of these substances. A survey about the use of CPA and LHRH agonists in forensic hospitals in Germany shows that half of the patients treated with any kind of (anti-) hormonal agents received an LHRH agonist. The authors present a protocol on side effects, contraindications, and monitoring of CPA and LHRH agonists and develop an algorithm for differential pharmacotherapy of paraphilias.  相似文献

In this report, three cases of suicide by an electric power drill are described. In the first case, a man aged 51 was found with four penetrating wounds of the head and chest. The second case involves a 56-year-old man who suffered a penetrating craniocerebral injury and the third case involves a 53-year-old man who suffered one head injury and two chest injuries. In the first two cases, the victims were found dead. In the third case, the victim survived his injuries for 28 hours. The case histories and the post-mortem examinations revealed no evidence of homicide.  相似文献

The trafficking of migrants around the world hasbecome a multi-billion-dollar business for criminalorganisations. Over the last ten years, thousands ofmigrants have been moved illegally acrossinternational borders with the assistance ofprofessional trafficking organisations.The increasing number of people forced or willing tomove abroad as well as the restrictions placed onlegitimate migration systems have translated intoorganized crime. Around the world, traffickingorganisations have learned to take advantage of thisstructural inequality, creating sophisticated channelsof illegal migration while exploiting those forced orwilling to migrate.This article seeks to examine traffickingorganisations in light of the most recent theories andinterpretations of organized crime, that is theeconomic analysis of transnational criminalorganisations. With respect to the elaboration offuture countermeasures on national, regional andinternational levels, the aim of this article is toidentify more precisely the major organisational andoperational features of the migrant traffickingbusiness.The article begins with an introductory discussion ofthe economic approach to organized crime in part 1.Part 2 analyses the illegal market in which criminalorganisations, in particular traffickers, operate.This provides the working basis for the examination ofthe migrant trafficking organisation in part 3 of thearticle.  相似文献

Although the Cyprus problem is basically an international questionand a geopolitical issue, the problem's domestic aspects aredirectly related to its international dimension. Resolutionof the problem's domestic aspects, within the framework of afederal constitutional arrangement based on the high-level agreementsof 1977 and 1979, the relevant United Nations resolutions, andthe provisions of the European Union acquis communautaire isperhaps possible. A federal system is a compromise between aunitary state, as initially desired by the Greek Cypriot majority-community,and a confederation, as currently pursued by the Turkish Cypriotminority-community with the support of Turkey. Nevertheless,even though federation is the agreed framework for a solution,a sizable proportion of Greek Cypriots express misgivings abouta federal solution because they fear that what is actually beingdiscussed is a system lying between federation and confederation.A viable federal solution would create a pluralist democraticstate with a market-oriented economy in the Eastern Mediterranean.Given that the Republic of Cyprus is on its way to joining theEU, the EU could play a substantive role in promoting such anoutcome. From a geopolitical perspective, a united Cyprus, asa member of the EU, would be an asset to the EU and also contributeto stability and security in the Eastern Mediterranean.  相似文献
