Die koordinationschemische Ambivalenz zweier mesoionischer Triazoliumaminide
(2020-05)
Die vorliegende Arbeit beleuchtet die Koordinationschemie zweier Mesoionen, die in Abhängigkeit vom angebotenen Zentralatom als N-heterocyclische Carben- (NHC-) oder Amido-Liganden fungieren. Durch Tautomerisierung der Triazoliumaminid-Form zum korrespondierenden Amino-NHC ermöglichen das seit über einem Jahrhundert bekannte analytische Reagenz »Nitron« (1) sowie dessen in dieser Arbeit entwickeltes Alkyl-Homolog 1-tert-Butyl-4-methyl-1,2,4-triazol-4-ium-3-tert-butylaminid (2) einen bequemen Zugang zur Chemie der ...

Regeln, Traditionen, Urteile: Verbale Höflichkeit und wie sie gelingt
(De Gruyter, 2020)
Das Gelingen von Gesprächen basiert entscheidend auf verbaler Höflichkeit, die dem Gesprächspartner Wertschätzung und Achtung vermittelt. Die Erwartungen an verbale Höflichkeit und die Bedingungen ihres Gelingens werden im Folgenden auf der Grundlage eines Modells der Gesprächsforschung dargestellt, das sich von Eugenio Coserius System der Sprachkompetenz herleitet (Coseriu 2007). Das Modell unterscheidet drei Wissenstypen. Diese gestalten als Regeln und Traditionen das Sprechen und können nach drei verschiedenen ...

Designing a Conversational Agent as a Formative Course Evaluation Tool
(GITO Verlag, 2020)
Today’s graduating students face ever-changing environments when they enter their job life. Educational institutions must therefore continuously develop their course structure and content in order to prepare their students to be future employees. A very important means for developing the courses is the students’ course evaluations. Due to financial and organizational restrictions, these course evaluations are usually carried out quantitatively and at the end of the semester. However, past research has shown that this ...

Unlocking Transfer Learning in Argumentation Mining: A Domain-Independent Modelling Approach
(GITO Verlag, 2020)
Argument identification is the fundamental block of every Argumentation Mining pipeline, which in turn is a young upcoming field with multiple applications ranging from strategy support to opinion mining and news fact-checking. We developed a model, which is tackling the two biggest practical and academic challenges of the research field today. First, it addresses the lack of corpus-agnostic models and, second, it tackles the problem of human-labor-intensive NLP models being costly to develop. We do that by suggesting ...

Governance for Decent Work in Agricultural Globalisation
(2021)
In the past decades, the agricultural world has become smaller as international food businesses have become organised around a global production network. One of the main factors for the introduction of a more decentralised and flexible food and agricultural system was the wage difference between Global North and Global South actors. In addition, Global South countries have facilitated the spread of Global Agricultural Value Chain/Global Agricultural Production Networks (GAVC/GAPNs) through promoting export processing ...

Fabrication and characterization of diamond nanopillars, waveguides and AFM tips with incorporated color centers
(2020-06)
Diamond is a unique material with outstanding properties and the perfect host for different crystal defects in its lattice, so-called color centers, which provide exceptional spin properties, rendering them a promising platform for the development of novel devices and components in quantum information technologies (QIT) and quantum sensing applications. To overcome diamond's high internal reflection due to its high refractive index, color centers need to be incorporated in photonic diamond structures, leading to ...
