Liming effects on reproductive growth and yield components of maize grown on an acid rainforest soil
(2019-12-03)
Maize was planted on limed and unlimed plots to study the effect of soil acidity on reproductive growth and yield components of the crop in Owerri southeastern Nigeria. Eight (8) maize varieties (Factor A) and two lime levels (0 and 2 t ha-1, Factor B) were arranged as a factorial experiment in a randomised complete block design with three replications. The number of days to 50 % anthesis and silking, anthesis-silking interval (ASI), physiological maturity and grain filling duration were measured to determine the ...

Effects of climate change on fungal community structure and organic matter turnover in soil profiles along elevation gradients in alpine ecosystems
(2019-10)
Although elevation patterns of diversity for plants and animals are well known, understanding of variations in fungal community structure along elevation gradients is limited. Soil fungi play an important role in soil microbial communities, where they improve soil organic matter (SOM) turnover and nutrient circulation. Hence, any change in fungal community structure will have strong effects on soil and ecosystem functioning. The main purpose of this thesis is therefore to investigate how climate induced shifts in ...

Reading a short story changes children’s sustainable behavior in a resource dilemma
(2019-12-02)
Fostering sustainable behavior in children and adolescents should be a central aim of today’s education. Even though the interplay of factors affecting sustainable behavior is complex, simple interventions can be effective too. In the current study, 10-year-olds (N = 132) were read a short story about two foresters who collectively used a forest to gain timber, facing a resource dilemma that involved striving for maximizing their individual profit while sustaining the forest. In the story, the foresters solved the ...

Steuerung im deutschen Gesundheitswesen?
(2019-06)
Die Dissertation widmet sich der Prüfung des – die deutsche gesundheitspolitische Diskussion dominierenden und maßgeblich von der orthodoxen Gesundheitsökonomie geprägten – Paradigmas der Steuerung ärztlichen Verhaltens mittels monetärer Anreize. Als „Prüfrahmen“ dienen die strukturierten Behandlungsprogramme (DMP) nach § 137f SGB V und die integrierte Versorgung (IV) nach §§ 140a ff. SGB V, die als deutsche Managed Care-Derivate maßgeblich von diesem Paradigma geleitet sind und, wie die Arbeit zeigt, in der ...

Schrift und Bild gesellt sich gern
(LiteraturWissenschaft.de, 2019-05)
Schrift und Bild? Schrift als Bild? Schriftbild? Bild(in)schrift? Dass sich zwei so große Themenkreise notwendigerweise mehrere Schnittflächen teilen müssen, liegt auf der Hand. Und da in einer generell primär visuell organisierten Gegenwart spätestens seit dem iconic turn die Forschungslandkarte gespickt ist mit Reißzwecken, auf denen Fahnenworte wie etwa die allenthalben diskutierten ‚Text-Bild-Relationen‘ prangen, ist die vorgenommene Fokussierung wichtig, richtig und konsequent. Boris Roman Gibhardt und Johannes ...

Towards Effective Natural Language Application Development
(2019)
There is a current trend that more and more computer programs analyze written or spoken natural language. For example, DVAs, IE systems, machine translation systems, and many other types of programs process natural language in order to solve specific use cases when interacting with humans via natural language. Amazon, Google, and Mycroft AI are just some of the companies that have produced DVAs capable of interacting with humans via voice. Such NLP applications use techniques from computer science and artificial ...

Discovering Knowledge in Bipartite Graphs with Formal Concept Analysis
(2019)
Since the 1970s knowledge based approaches are a crucial part of artificial intelligence (AI) research. In this work we investigate data sets in the form of bipartite graphs, i.e., graphs where a bipartition of the vertex set respecting the edge set can be found, for knowledge. To this end we first relate those bipartite graphs to the structure formal context, as used in formal concept analysis (FCA). This link enables us to employ the whole tool-set of FCA to bipartite graphs and therefore, notably, to bipartite ...

Krisenbewältigung und Professionalität von Supervisoren
(2019)
Die vorliegende Arbeit entstand aus dem Interesse, die Entstehung eines professionellen Habitus bei langjährig erfahrenen Supervisoren nachzuvollziehen und diesen Prozess mittels empirischer Methoden zu dokumentieren. Bisher liegen m.W. keine Studien vor, die anhand von narrativ-biographischen Interviews mit Supervisoren die Bedeutung der Bewältigung von Krisen für die Bildung eines professionellen supervisorischen Habitus untersuchen, geschweige denn Nachweise für diesen Zusammenhang zu erbringen.
Der Ausgangsgedanke ...

High-Speed 1.55 µm Quantum Dot Lasers with Electronically Coupled Quantum Well - Dot Active Regions
(2019-07-31)
The expansion of long-distance data communication at a wavelength of 1.55 µm calls for larger data transfer rates. Consequently, an improvement of emission and modulation properties of lasers emitting in this wavelength region is of high interest. The utilization of so-called tunnel-injection (TI) structures in InP-based quantum dot (QD) lasers is promising to fulfill this task. The aim of this thesis was the realization and analysis of TI structures in the lattice matched InP material system and incorporation into ...

Las tradiciones discursivas: conceptualización teórica y aplicación al discurso de la crisis
(Peter Lang, 2019)
Discourses and texts follow patterns and have their own traditions. The concept of discourse tradition as a form of cultural knowledge that is linked to dimensions of textuality and cooperation is, on a theoretical level, combined with current models of discourse and text linguistics and put into practice by analyzing a corpus of Argentinian press texts.
