Melting Space Herosé? : Die „Stadt am Seerhein“ in Konstanz aus stadt- und raumwissenschaftlicher Perspektive

Das Projekt „Melting Space Herosé“ entstand im Rahmen des Projektseminars „Raum-Expedition: Konstanz“ im Sommersemester 2010 an der Universität Konstanz. Untersucht wurde das Herosé-Areal, ein ehemaliges Industrie- Gebiet, das rechtsrheinisch zwischen dem Stadtteil Petershausen und dem Seerhein liegt. Die Konstanzer Altstadt liegt in Gehweite und ist vom Herosé aus über eine Fahrradbrücke über den Rhein in ca. 5 Minuten erreichbar. Das Herosé-Areal wurde in den letzten Jahren neu bebaut. Es entstanden 5 große Gebäude in U-Form (die so genannten "Hofgärten"), zum Seerhein hin geöffnet, mit Blick aufs Wasser und auf die linksrheinische Stadtseite. Aktuell wird das 5. Gebäude gebaut und daran anschließend ein "Kompetenzzentrum" und ein Hotelkomplex. Der Uferbereich wurde gezielt als Naherholungsgebiet umgesetzt: Park, Uferpromenade und große, zum Rhein abfallende Steinstufen laden zum Verweilen ein. Planungsziele waren: Petershausen ans Wasser zu bringen, eine Verzahnung von öffentlichen und privaten Räumen zu schaffen und zugleich ruhiges, zentrumsnahes Wohnen zu ermöglichen. Das führte in Folge der Fertigstellung der ersten Hofgärten zu massiven Konflikten zwischen AnwohnerInnen und ParkbesucherInnen. Die AnwohnerInnen, die zum Großteil RentnerInnen sind, haben sich die hochpreisigen Wohnungen für den Lebensabend gegönnt. Allerdings hatten sie nicht damit gerechnet, dass die öffentlichen Räume direkt am Wasser und an einer Uferpromenade tatsächlich intensiv genutzt werden, im Sommer auch bis in die späten Abendstunden. So beginnen Konflikte, in welche Sicherheitsdienste, Polizeieinsätze, Glas- und Alkoholverbote, Bürgerinitiativen, Stadtplanung, Baubürgermeister, Wohnbaugesellschaften etc. verflochten sind. Diesen Blackbox-artigen Raum analysierte das Studierendenteam Julia Adamek, Magdalena Bogatko, Siri Grunow, Michael Hubrich, Anja Joos und Julia Slotty im Rahmen einer triangulativen Studie. Neben Dokumentenanalysen und teilnehmenden Beobachtungen wurden eine Vielzahl von Experteninterviews und zwei teilstandardisierte Befragungen durchgeführt. Die Ergebnisse überzeugen nicht nur auf der wissenschaftlichen Ebene sondern leisten darüber hinaus auch einen Beitrag zu aktuellen Fragen der städtischen Politik in Konstanz

Ontology for Transcription of ATC Speech Commands of SESAR 2020 Solution PJ.16-04

Nowadays Automatic Speech Recognition (ASR) applications are increasingly successful in the air traffic (ATC) domain. Paramount to achieving this is collecting enough data for speech recognition model training. Thousands of hours of ATC communication are recorded every day. However, the transcription of these data sets is resource intense, i.e. writing down the sequence of spoken words, and more importantly, interpreting the relevant semantics. Many different approaches including CPDLC (Controller Pilot Data Link Communications) currently exist in the ATC community for command transcription, a fact that e.g. complicates exchange of transcriptions. The partners of the SESAR funded solution PJ.16-04 are currently developing on a common ontology for transcription of controller-pilot communications, which will harmonize integration of ASR into controller working positions. The resulting ontology is presented in this paper

A multicenter, open-label, controlled trial on acceptance, convenience, and complications of rechargeable internal pulse generators for deep brain stimulation: the Multi Recharge Trial

OBJECTIVE Rechargeable neurostimulators for deep brain stimulation have been available since 2008, promising longer battery life and fewer replacement surgeries compared to non-rechargeable systems. Long-term data on how recharging affects movement disorder patients are sparse. This is the first multicenter, patient-focused, industry-independent study on rechargeable neurostimulators. METHODS Four neurosurgical centers sent a questionnaire to all adult movement disorder patients with a rechargeable neurostimulator implanted at the time of the trial. The primary endpoint was the convenience of the recharging process rated on an ordinal scale from "very hard" (1) to "very easy" (5). Secondary endpoints were charge burden (time spent per week on recharging), user confidence, and complication rates. Endpoints were compared for several subgroups. RESULTS Datasets of 195 movement disorder patients (66.1% of sent questionnaires) with Parkinson's disease (PD), tremor, or dystonia were returned and included in the analysis. Patients had a mean age of 61.3 years and the device was implanted for a mean of 40.3 months. The overall convenience of recharging was rated as "easy" (4). The mean charge burden was 122 min/wk and showed a positive correlation with duration of therapy; 93.8% of users felt confident recharging the device. The rate of surgical revisions was 4.1%, and the infection rate was 2.1%. Failed recharges occurred in 8.7% of patients, and 3.6% of patients experienced an interruption of therapy because of a failed recharge. Convenience ratings by PD patients were significantly worse than ratings by dystonia patients. Caregivers recharged the device for the patient in 12.3% of cases. Patients who switched from a non-rechargeable to a rechargeable neurostimulator found recharging to be significantly less convenient at a higher charge burden than did patients whose primary implant was rechargeable. Age did not have a significant impact on any endpoint. CONCLUSIONS Overall, patients with movement disorders rated recharging as easy, with low complication rates and acceptable charge burden

Uptake and tracer kinetics of O-(2-18F-fluoroethyl)-l-tyrosine in meningiomas: preliminary results.

PurposeO-(2-[18F]Fluoroethyl)-l-tyrosine (18F-FET) is a well-established PET tracer for the imaging of cerebral gliomas, but little is known about 18F-FET uptake in meningiomas. The aim of this study was to explore 18F-FET kinetics and tumour-to-background contrast in meningiomas of various histologies.MethodsA group of 24 patients with suspected cerebral meningioma on MRI/CT had an additional dynamic 18F-FET PET scan prior to surgery. Time–activity curves (TAC) of 18F-FET uptake in the tumours and tumour-to-brain ratios (TBR) for early (3 – 14 min after injection) and late 18F-FET uptake (20 – 40 min after injection) were analysed and compared with histological subtypes and WHO grade. 18F-FET uptake in critical structures in the skull base was also evaluated in terms of tumour-to-tissue (T/Tis) ratio.ResultsTBR of 18F-FET uptake in meningiomas was significantly higher in the early phase than in the late phase (3.5 ± 0.8 vs. 2.2 ± 0.3; P 1.2 in all patients for the periorbita, sphenoidal sinus, pituitary gland, tentorium, bone and brain, in more than 90 % of patients for the mucosa and dura, but in only 63 % of patients for the cavernous sinus.Conclusion18F-FET PET may provide additional information for noninvasive grading of meningiomas and possibly for the discrimination of tumour in critical areas of the skull base. A further evaluation of 18F-FET PET in meningiomas appears to be justified
