Die Gesellschaft und ihr Recht ignorieren diese Variabilitäten jenseits der natürlichen Geschlechtlichkeit jedoch mit Blick auf Orientierungsbedürfnisse weitgehend: Familien- und personenstandsrechtliche Zuschreibungen müssen eindeutig sein, Veränderungen des biologischen Geschlechts kommen nur in seltenen Ausnahmefällen in Betracht, die gesellschaftlichen Vorstellungen über den Freiraum an „sexueller Selbstbestimmung“ werden an den Grenzen strafrechtlich abgesichert und jene, die sich nicht daran halten, gelten in der Rechtspraxis entweder als schuldfähig oder haben mit u.U. langjährigem Freiheitsentzug im Rahmen der Sicherungsverwahrung zu rechnen. Dieses Spannungsfeld zwischen individueller Disposition und gesellschaftlicher Erwartung war Gegenstand eines Workshops, der am 20. November 2009 gemeinsam vom Institut für Humangenetik der Universitätsmedizin Göttingen und dem Zentrum für Medizinrecht der Juristischen Fakultät veranstaltet wurde. Der vorliegende Band enthält die Resultate eines interdisziplinären Dialogs von Experten/Innen aus der Humangenetik, der Sexualforschung, der Soziologie, des Medizinrechts und der forensischen

o?springs.” AI researchers have been focusing on developing and employing strong methods that are capable of solving complex real-life problems. The 18th International Conference on Industrial & Engineering Applications of Arti?cial Intelligence & Expert Systems (IEA/AIE 2005) held in Bari, Italy presented such work performed by many scientists worldwide. The Program Committee selected long papers from contributions presenting more complete work and posters from those reporting ongoing research. The Committee enforced the rule that only original and unpublished work could be considered for inclusion in these proceedings. The Program Committee selected 116 contributions from the 271 subm- ted papers which cover the following topics: arti?cial systems, search engines, intelligent interfaces, knowledge discovery, knowledge-based technologies, na- ral language processing, machine learning applications, reasoning technologies, uncertainty management, applied data mining, and technologies for knowledge management. The contributions oriented to the technological aspects of AI and the quality of the papers are witness to a research activity clearly aimed at consolidating the theoretical results that have already been achieved. The c- ference program also included two invited lectures, by Katharina Morik and Roberto Pieraccini. Manypeoplecontributedindi?erentwaystothesuccessoftheconferenceand to this volume. The authors who continue to show their enthusiastic interest in applied intelligence research are a very important part of our success. We highly appreciate the contribution of the members of the Program Committee, as well as others who reviewed all the submitted papers with e?ciency and dedication.Lecture Notes in Artificial Intelligence,2945-9141 ;3533Artificial intelligenceComputer sciencePattern recognition systemsSoftware engineeringApplication softwareUser interfaces (Computer systems)Human-computer interactionArtificial IntelligenceTheory of ComputationAutomated Pattern RecognitionSoftware EngineeringComputer and Information Systems ApplicationsUser Interfaces and Human Computer InteractionArtificial intelligence.Computer science.Pattern recognition systems.Software engineering.Application software.User interfaces (Computer systems).Human-computer interaction.Artificial Intelligence.Theory of Computation.Automated Pattern Recognition.Software Engineering.Computer and Information Systems Applications.User Interfaces and Human Computer Interaction.006.3Ali Moonis1231888Esposito Floriana1947-1752275MiAaPQMiAaPQMiAaPQBOOK9910484241803321Innovations in applied artificial intelligence4187532UNINA
