Konsekutivdolmetschen und Notation

Die Dissertation "Konsekutivdolmetschen und Notation" (Andres 2002) ist eine experimentelle Studie. Mit Hilfe einer von den Germersheimer Technikern konzipierten Spezialkamera wurde die Notizennahme von insgesamt 28 ProbandInnen, denen über Video die Fernsehansprache des französischen Staatspräsidenten zum Jahreswechsel 1996/1997 eingespielt wurde, gefilmt. Das Besondere an diesen Filmaufnahmen der Notizen war die mitlaufende Zeitschaltuhr. Damit konnte der zeitliche Abstand (Décalage) zur Originalrede gemessen werden. In der Verschriftung wurden die Originalrede, die Notizen und die Wiedergabe in ihrem temporalen Verlauf aufgezeichnet. Auch nonverbale Elemente wurden durch in Klammern hinter die jeweilige Äußerung gesetzte Anmerkungen integriert. Die Leistungen der ProbandInnen wurden von drei Dozentinnen bewertet. Die Auswertung der empirischen Daten erfolgte unter den Aspekten Effizienz und Knappheit, Quantität und Auswahl, Informationsstrukturierung, Décalage, Wissen und Erfahrung, Text als kommunikatives Ganzes. Auswertung der Dolmetschleistungen: Konsekutivdolmetschen ist eine komplexe Gesamtoperation, die sich aus zahlreichen miteinander vernetzten Teilen zusammensetzt. Faktoren wie Übung, Erfahrung, Wissen, das Verfügen über Sachkenntnis und Problemlösestrategien, spielen in diesem Prozess eine erhebliche Rolle. Daher ist es sinnvoll, im didaktischen Ansatz Einzeloperationen aus der Gesamtoperation herauszulösen und für Einzelbereiche die Fähigkeit zum Problemlösen zu trainieren. Die Grundvoraussetzung ist Verstehen, so dass vor allem Verstehenstechniken zu vermitteln sind. Insgesamt geht es darum, den Lernprozess so zu gestalten, dass Studierenden Strategien vermittelt werden, die es ihnen ermöglichen, defizitäre Daten der Textoberfläche durch differenzierte Erwartungsstrukturen zu ergänzen und zu lernen, Sinn zu konstruieren. In Bezug auf die Notation lassen die in der Untersuchung enthaltenen Daten den Schluss zu, dass es bei der Notation nicht um Fragen wie zielsprachliches oder ausgangssprachliches Notieren oder die Anzahl von Symbolen geht, sondern darum zu vermitteln, dass: (1) ein deutlich geschriebenes Notationssystem mit automatisierten Abkürzungsregeln und einem eindeutigen Stamm an Symbolen Zeitersparnis bewirkt, die für andere Operationen genutzt werden kann; (2) Verben und Tempusangaben für die Rekonstruktion des Gesagten ein wesentlicher Faktor sind; (3) Informationsgewichtung und -strukturierung in den Notizen die Verstehensoperationen intensivieren und die Textproduktion erleichtern; (4) Segmentierung und räumliche Anordnung in den Notizen das Zuordnen erleichtern und die Sprachproduktion positiv beeinflussen; (5) die Notation von Verknüpfungsmitteln ein wesentliches Element für die Herstellung von Kohäsion ist; (6) das Décalage in Abhängigkeit vom Faktor Verstehen Schwankungen unterworfen ist und sein darf; (7) jede Person das für sie individuelle Décalage herausfinden muss; (8) ein anhaltendes Décalage von mehr als 7 Sekunden zu Defiziten im Verstehens- oder im Notationsprozess führt; (9) diskontinuierliches Notieren zur Informationsstrukturierung oder -vervollständigung hilfreich sein kann; (10) rhetorische Merkmale in der Textproduktion leichter berücksichtigt werden, wenn diese in den Notizen markiert sind.rnSchließlich haben die Beobachtungen gezeigt, wie hilfreich für die Studierenden eine intensive Auseinandersetzung mit der Notation ist, wie wichtig ein trainiertes, verlässliches, effizientes Notationssystem als eine Teiloperation ist, die den Verstehensprozess stützt und damit entscheidenden Einfluss auf die Qualität der zielsprachlichen Umsetzung nimmt.

Cooperative Cognitive Wireless Networks over TV White and Gray Spaces

Wireless networks rapidly became a fundamental pillar of everyday activities. Whether at work or elsewhere, people often benefits from always-on connections. This trend is likely to increase, and hence actual technologies struggle to cope with the increase in traffic demand. To this end, Cognitive Wireless Networks have been studied. These networks aim at a better utilization of the spectrum, by understanding the environment in which they operate, and adapt accordingly. In particular recently national regulators opened up consultations on the opportunistic use of the TV bands, which became partially free due to the digital TV switch over. In this work, we focus on the indoor use of of TVWS. Interesting use cases like smart metering and WiFI like connectivity arise, and are studied and compared against state of the art technology. New measurements for TVWS networks will be presented and evaluated, and fundamental characteristics of the signal derived. Then, building on that, a new model of spectrum sharing, which takes into account also the height from the terrain, is presented and evaluated in a real scenario. The principal limits and performance of TVWS operated networks will be studied for two main use cases, namely Machine to Machine communication and for wireless sensor networks, particularly for the smart grid scenario. The outcome is that TVWS are certainly interesting to be studied and deployed, in particular when used as an additional offload for other wireless technologies. Seeing TVWS as the only wireless technology on a device is harder to be seen: the uncertainity in channel availability is the major drawback of opportunistic networks, since depending on the primary network channel allocation might lead in having no channels available for communication. TVWS can be effectively exploited as offloading solutions, and most of the contributions presented in this work proceed in this direction.

Potential effect of marine traffic on white-beaked dolphin (Lagenorhynchus albirostris) distribution and behaviour in Faxaflói Bay, southwest Iceland

Faxaflói bay is a short, wide and shallow bay situated in the southwest of Iceland. Although hosting a rather high level of marine traffic, this area is inhabited by many different species of cetaceans, among which the white-beaked dolphin (Lagenorhynchus albirostris), found here all year-round. This study aimed to evaluate the potential effect of increasing marine traffic on white-beaked dolphins distribution and behaviour, and to determine whether or not a variation in sighting frequencies have occurred throughout years (2008 – 2014). Data on sightings and on behaviour, as well as photographic one, has been collected daily taking advantage of the whale-watching company “Elding” operating in the bay. Results have confirmed the importance of this area for white-beaked dolphins, which have shown a certain level of site fidelity. Despite the high level of marine traffic, this dolphin appears to tolerate the presence of boats: no differences in encounter durations and locations over the study years have occurred, even though with increasing number of vessels, an increase in avoidance strategies has been displayed. Furthermore, seasonal differences in probabilities of sightings, with respect to the time of the day, have been found, leading to suggest the existence of a daily cycle of their movements and activities within the bay. This study has also described a major decline in sighting rates throughout years raising concern about white-beaked dolphin conservation status in Icelandic waters. It is therefore highly recommended a new dedicated survey to be conducted in order to document the current population estimate, to better investigate on the energetic costs that chronic exposure to disturbances may cause, and to plan a more suitable conservation strategy for white-beaked dolphin around Iceland.

The arcuate fasciculus: an along-tract analysis with white matter probabilistic tractography

Il cervello umano è composto da una rete complessa, formata da fasci di assoni, che connettono le diverse aree cerebrali. Il fascio arcuato collega l’area imputata alla com- prensione del linguaggio con quella dedicata alla sua produzione. Il fascio arcuato è presente in entrambi gli emisferi cerebrali, anche se spesso è utilizzato prevalente- mente il sinistro. In questa tesi sono state valutate, in un campione di soggetti sani, le differenze tra fascio arcuato destro e sinistro, utilizzando la trattografia, metodica avanzata e non invasiva che permette la ricostruzione della traiettoria delle fibre con immagini RM (Risonanza Magnetica) pesate in diffusione. A questo scopo ho utilizzato un algoritmo probabilistico, che permette la stima di probabilità di connessione della fibra in oggetto con le diverse aree cerebrali, anche nelle sedi di incrocio con fibre di fasci diversi. Grazie all’implementazione di questo metodo, è stato possibile ottenere una ricostruzione accurata del fascio arcuato, an- che nell’emisfero destro dove è spesso critica, tanto da non essere possibile con altri algoritmi trattografici. Parametrizzando poi la geometria del tratto ho diviso il fascio arcuato in venti seg- menti e ho confrontato i parametri delle misure di diffusione, valutate nell’emisfero destro e sinistro. Da queste analisi emerge un’ampia variabilità nella geometria dell’arcuato, sia tra diversi soggetti che diversi emisferi. Nell’emisfero destro l’arcuato incrocia maggiormente fibre appartenenti ad altri fasci. Nell’emisfero sinistro le fibre dell’arcuato sono più compatte e si misura anche una maggiore connettività con altre aree del cervello coinvolte nelle funzioni linguistiche. Nella seconda fase dello studio ho applicato la stessa metodica in due pazienti con lesioni cerebrali, con l’obiettivo di testare il danno del fascio arcuato ipsilaterale alla lesione e stimare se nell’emisfero controlaterale si innescassero meccanismi di plastic- ità strutturale. Questa metodica può essere implementata, in un gruppo di pazienti omogenei, per identificare marcatori RM diagnostici nella fase di pianificazione pre- chirurgica e marcatori RM prognostici di recupero funzionale del linguaggio.

White matter integrity associated with volitional motor activity

Variations of white matter integrity have been associated with interindividual differences in brain function. Still, little is known about the impact of white matter integrity on quantitative motor behaviour. Diffusion tensor imaging and continuous wrist actigraphy were measured on the same day in 12 individuals. Fractional anisotropy as measure of white matter integrity was correlated with the motor activity level. Positive correlations of fractional anisotropy and activity level were detected in the cingulum and the right superior longitudinal fasciculus underneath the precentral gyrus. Negative correlations were found in the left corticobulbar tract, in the right posterior corpus callosum and in the left superior longitudinal fasciculus. Volitional motor activity was associated with white matter integrity in motor relevant fiber tracts.

Nocturnal dipping behaviour in normotensive white children and young adults in response to changes in salt intake

Nocturnal nondipping is a feature of salt-sensitive, hypertensive individuals. In normotensive children and adults, the impact of salt intake on circadian blood pressure (BP) rhythm is not well defined.

Reversal of established lupus nephritis and prolonged survival of New Zealand black x New Zealand white mice treated with the topoisomerase I inhibitor irinotecan

Systemic lupus erythematosus is a chronic autoimmune disorder that predominantly affects women of childbearing age. Lupus-associated glomerulonephritis is a major cause of mortality in these patients. Current treatment protocols for systemic lupus erythematosus include cyclophosphamide, prednisolone, azathioprine, and mycophenolate mofetil. However, in mice none of these agents alone or in combination were shown to reverse established proteinuria. Using New Zealand Black x New Zealand White F1 mice, we report that administration of the topoisomerase I inhibitor irinotecan from week 13 completely prevented the onset of proteinuria and prolonged survival up to at least 90 wk without detectable side effects. Furthermore, application of irinotecan to mice with established lupus nephritis, as indicated by grade 3+ (> or =300 mg/dl) and grade 4+ (> or =2000 mg/dl) proteinuria and, according to a median age of 35 wk, resulted in remission rates of 75% and 55%, respectively. Survival was significantly prolonged with 73 wk (grade 3+ and 4+ combined) versus 40 wk for control animals. Although total IgG and anti-dsDNA Abs in the serum and mesangial IgG deposits in the kidneys were not reduced in irinotecan-treated mice, subendothelial immune deposits were considerably diminished, suggesting a prevention of glomerular basement membrane disruption. This effect was accompanied by increased rates of ssDNA breaks and inhibition of renal cell apoptosis being different to what is known about irinotecan in anticancer therapy. In conclusion, our data provide evidence that irinotecan might represent an entirely new strategy for the treatment of systemic lupus erythematosus.

Altered cardiovascular rhythmicity in children with white coat and ambulatory hypertension

Adults with ambulatory hypertension or white coat hypertension (WCH) display abnormal cardiovascular rhythms. We studied cardiovascular rhythms by Fourier analysis of 24-h ambulatory blood pressure (BP) measurement profiles in 129 hypertensive children, 54 children with WCH, and 146 age-, height-, and gender-matched healthy subjects. The day/night mean arterial pressure ratio was lower in hypertensive and patients with WCH compared with controls (1.13 versus 1.16 versus 1.21, respectively; p < 0.0001). Eighty-five percent of controls were dippers compared with 74% of WCH (n.s.) and 64% of patients with ambulatory hypertension (p < 0.0001). The prevalence of 24-h rhythms was similar among the groups, but prevalence of 12-h BP rhythms was increased in hypertensive (67%) and WCH (72%) compared with controls (51%, p < 0.0001). The amplitudes of the 24-, 8-, and 6-h BP rhythms were reduced in hypertensive and WCH compared with controls (p < 0.05). Hypertensive and patients with WCH displayed delayed 24-, 12-, 8-, 6-h acrophases in comparison with controls (p < 0.05). In conclusion, hypertensive children exhibit abnormal cardiovascular rhythmicity compared with controls, especially a higher prevalence of nondipping compared with normotensive children. Abnormalities in patients with WCH are intermediate between healthy children and patients with ambulatory hypertension.

Late Infiltration of Post-orthodontic White Spot Lesions

White spot lesion (WSL) infiltration has been recommended immediately after debonding of orthodontic brackets. It is however not clear if established inactive WSLs can also be masked through infiltrationOrthodontic treatment of a 19-year-old patient had to be terminated prematurely due to development of multiple WSLs of varying severity. Three months after debonding, the patient presented for lesion infiltration. After etching with 15% HCl gel and re-wetting of the dried surfaces it seemed that a good outcome could be expected. Lesion infiltration led to complete masking of less severe WSLs. The visual appearance of moderate and severe WSLs was improved but they were still visible after treatment.Inactive WSLs may not represent an increased caries risk, but patients are often bothered esthetically. Infiltration by repeated etching might be a viable approach even for inactive WSLs. Controlled clinical trials are needed to investigate the long-term performance of this technique.

Alterations of white matter integrity related to motor activity in schizophrenia

Altered structural connectivity is a key finding in schizophrenia, but the meaning of white matter alterations for behavior is rarely studied. In healthy subjects, motor activity correlated with white matter integrity in motor tracts. To explore the relation of motor activity and fractional anisotropy (FA) in schizophrenia, we investigated 19 schizophrenia patients and 24 healthy control subjects using Diffusion Tensor Imaging (DTI) and actigraphy on the same day. Schizophrenia patients had lower activity levels (AL). In both groups linear relations of AL and FA were detected in several brain regions. Schizophrenia patients had lower FA values in prefrontal and left temporal clusters. Furthermore, using a general linear model, we found linear negative associations of FA and AL underneath the right supplemental motor area (SMA), the right precentral gyrus and posterior cingulum in patients. This effect within the SMA was not seen in controls. This association in schizophrenia patients may contribute to the well known dysfunctions of motor control. Thus, structural disconnectivity could lead to disturbed motor behavior in schizophrenia.
