Das Jahreskaddisch ist ein Spezifikum der westaschkenasischen Liturgie. Es wird am Abend und am Morgen des Simchat-Tora-Festes vorgetragen und ist aus den wichtigsten musikalischen Motiven des Kaddisch-Gebetes innerhalb des gesamten jüdischen Jahreszyklus zusammengesetzt. Anhand von Tonaufnahmen wurde das Jahreskaddisch der Frankfurter Tradition transkribiert und seine einzelnen melodischen Bestandteile identifiziert. Die vorgestellte Kaddischmelodie wird im heutigen Gottesdienst in Frankfurt a. M. nicht mehr vorgetragen.
Die Zeitschrift möchte die fruchtbare und facettenreiche Kultur des Judentums sowie seine Berührungspunkte zur Umwelt in den unterschiedlichen Bereichen dokumentieren. Daneben dient die Zeitschrift als Forum zur Positionierung der Fächer Jüdische Studien und Judaistik innerhalb des wissenschaftlichen Diskurses sowie zur Diskussion ihrer historischen und gesellschaftlichen Verantwortung.
The objective and motivation behind this research is to provide applications with easy-to-use interfaces to communities of deaf and functionally illiterate users, which enables them to work without any human assistance. Although recent years have witnessed technological advancements, the availability of technology does not ensure accessibility to information and communication technologies (ICT). Extensive use of text from menus to document contents means that deaf or functionally illiterate can not access services implemented on most computer software. Consequently, most existing computer applications pose an accessibility barrier to those who are unable to read fluently. Online technologies intended for such groups should be developed in continuous partnership with primary users and include a thorough investigation into their limitations, requirements and usability barriers. In this research, I investigated existing tools in voice, web and other multimedia technologies to identify learning gaps and explored ways to enhance the information literacy for deaf and functionally illiterate users. I worked on the development of user-centered interfaces to increase the capabilities of deaf and low literacy users by enhancing lexical resources and by evaluating several multimedia interfaces for them. The interface of the platform-independent Italian Sign Language (LIS) Dictionary has been developed to enhance the lexical resources for deaf users. The Sign Language Dictionary accepts Italian lemmas as input and provides their representation in the Italian Sign Language as output. The Sign Language dictionary has 3082 signs as set of Avatar animations in which each sign is linked to a corresponding Italian lemma. I integrated the LIS lexical resources with MultiWordNet (MWN) database to form the first LIS MultiWordNet(LMWN). LMWN contains information about lexical relations between words, semantic relations between lexical concepts (synsets), correspondences between Italian and sign language lexical concepts and semantic fields (domains). The approach enhances the deaf users’ understanding of written Italian language and shows that a relatively small set of lexicon can cover a significant portion of MWN. Integration of LIS signs with MWN made it useful tool for computational linguistics and natural language processing. The rule-based translation process from written Italian text to LIS has been transformed into service-oriented system. The translation process is composed of various modules including parser, semantic interpreter, generator, and spatial allocation planner. This translation procedure has been implemented in the Java Application Building Center (jABC), which is a framework for extreme model driven design (XMDD). The XMDD approach focuses on bringing software development closer to conceptual design, so that the functionality of a software solution could be understood by someone who is unfamiliar with programming concepts. The transformation addresses the heterogeneity challenge and enhances the re-usability of the system. For enhancing the e-participation of functionally illiterate users, two detailed studies were conducted in the Republic of Rwanda. In the first study, the traditional (textual) interface was compared with the virtual character-based interactive interface. The study helped to identify usability barriers and users evaluated these interfaces according to three fundamental areas of usability, i.e. effectiveness, efficiency and satisfaction. In another study, we developed four different interfaces to analyze the usability and effects of online assistance (consistent help) for functionally illiterate users and compared different help modes including textual, vocal and virtual character on the performance of semi-literate users. In our newly designed interfaces the instructions were automatically translated in Swahili language. All the interfaces were evaluated on the basis of task accomplishment, time consumption, System Usability Scale (SUS) rating and number of times the help was acquired. The results show that the performance of semi-literate users improved significantly when using the online assistance. The dissertation thus introduces a new development approach in which virtual characters are used as additional support for barely literate or naturally challenged users. Such components enhanced the application utility by offering a variety of services like translating contents in local language, providing additional vocal information, and performing automatic translation from text to sign language. Obviously, there is no such thing as one design solution that fits for all in the underlying domain. Context sensitivity, literacy and mental abilities are key factors on which I concentrated and the results emphasize that computer interfaces must be based on a thoughtful definition of target groups, purposes and objectives.
Historiografie und Publizistik haben den Kriegsausbruch von 1914 immer aus unterschiedlichen Blickwinkeln und mit wechselnden Intentionen behandelt. Dabei wurde deutlich, dass sich mit der Überwindung der nationalen Perspektive auf 1914 zugleich auch unser Blick auf die Verantwortlichkeit der einzelnen europäischen Regierungen erweitert hat. Damit ist die Kriegsschuldfrage, die gleich am Anfang der Debatte um 1914 gestanden hatte und gerade nach den Pariser Vorortverträgen instrumentalisiert worden war, eigentlich obsolet geworden und einer Perspektive gewichen, die, frei von tagespolitischen Belastungen, nationalen Feindbildern und Vorurteilen, Schuld und Verantwortung in ihren Verschränkungen mit dem politischen Entscheidungshandeln verdeutlicht und dabei auch die systemischen Voraussetzungen und Folgen in Rechnung stellt.
Mathematical modeling of biological systems is a powerful tool to systematically investigate the functions of biological processes and their relationship with the environment. To obtain accurate and biologically interpretable predictions, a modeling framework has to be devised whose assumptions best approximate the examined scenario and which copes with the trade-off of complexity of the underlying mathematical description: with attention to detail or high coverage. Correspondingly, the system can be examined in detail on a smaller scale or in a simplified manner on a larger scale. In this thesis, the role of photosynthesis and its related biochemical processes in the context of plant metabolism was dissected by employing modeling approaches ranging from kinetic to stoichiometric models. The Calvin-Benson cycle, as primary pathway of carbon fixation in C3 plants, is the initial step for producing starch and sucrose, necessary for plant growth. Based on an integrative analysis for model ranking applied on the largest compendium of (kinetic) models for the Calvin-Benson cycle, those suitable for development of metabolic engineering strategies were identified. Driven by the question why starch rather than sucrose is the predominant transitory carbon storage in higher plants, the metabolic costs for their synthesis were examined. The incorporation of the maintenance costs for the involved enzymes provided a model-based support for the preference of starch as transitory carbon storage, by only exploiting the stoichiometry of synthesis pathways. Many photosynthetic organisms have to cope with processes which compete with carbon fixation, such as photorespiration whose impact on plant metabolism is still controversial. A systematic model-oriented review provided a detailed assessment for the role of this pathway in inhibiting the rate of carbon fixation, bridging carbon and nitrogen metabolism, shaping the C1 metabolism, and influencing redox signal transduction. The demand of understanding photosynthesis in its metabolic context calls for the examination of the related processes of the primary carbon metabolism. To this end, the Arabidopsis core model was assembled via a bottom-up approach. This large-scale model can be used to simulate photoautotrophic biomass production, as an indicator for plant growth, under so-called optimal, carbon-limiting and nitrogen-limiting growth conditions. Finally, the introduced model was employed to investigate the effects of the environment, in particular, nitrogen, carbon and energy sources, on the metabolic behavior. This resulted in a purely stoichiometry-based explanation for the experimental evidence for preferred simultaneous acquisition of nitrogen in both forms, as nitrate and ammonium, for optimal growth in various plant species. The findings presented in this thesis provide new insights into plant system's behavior, further support existing opinions for which mounting experimental evidences arise, and posit novel hypotheses for further directed large-scale experiments.

Störungen des Hörvermögens
(2014)
Schwerhörigkeiten treten beim Menschen häufig auf und können angeboren oder erworben sein. Man unterscheidet in Schallleitungsschwerhörigkeiten, bei denen Schallaufnahme und Schallleitung in das Innenohr durch Fremdkörper, Infektionen, Verletzungen, Mittelohrbelüftungsprobleme und Fehlbildungen gestört sind und in Schallempfindungsschwerhörigkeiten, bei denen der Sinnesbereich des Innenohres, die Nervenleitung zum Hirnstamm oder die zentrale Verarbeitung im Gehirn betroffen sind. Ursächlich hierfür kommen neben vererbten Faktoren Infektionen, Verletzungen, Lärm, toxische Substanzen, Geburtsprobleme, Stoffwechselstörungen und Tumoren in Betracht. Bestehen Schwerhörigkeiten unbehandelt lange Zeit, kommt es – je nach Ausprägung – bei Kindern zu Störungen der Gehirn-, Sprachund emotionalen Entwicklung, bei allen Betroffenen auch zu Kommunikationsproblemen und zu Schwierigkeiten bei der Teilhabe am Leben in der sozialen Gemeinschaft. Schallleitungsschwerhörigkeiten können medizinisch behandelt und gebessert werden, während bei Schallempfindungsschwerhörigkeiten eine ursächliche medizinische Behandlung zur Zeit nicht möglich ist. In diesen Fällen ist die Versorgung mit Hörsystemen erforderlich. Hierzu zählt man, wiederum in Abhängigkeit vom Ausmaß der Schwerhörigkeit, IdO- und HdO-Hörgeräte, implantierbare Hörgeräte, cochleäre Implantate und Hirnstammimplantate. Bei Schwerhörigkeiten, die durch beruflichen Lärm verursacht sind, ist eine Herausnahme aus dem Lärmberuf Voraussetzung, um eine weitere Verschlechterung zu verhindern. Eine besondere Stellung kommt der einseitigen Schallempfindungsschwerhörigkeit zu, da sie bei Normalhörigkeit des anderen Ohres, seltener auffällt, den Betroffenen aber Probleme im täglichen Leben bereiten kann. Wichtig sind ihre Erkennung und Berücksichtigung, zum Beispiel in der Schule, am Arbeitsplatz und im Straßenverkehr. Dem bleibend hörbehinderten Menschen stehen nach dem Sozialgesetzbuch Hilfen und Vergünstigungen zu, um die durch die Hörbehinderung verursachten Nachteile zum Teil auszugleichen.
