Existence and Regularity Results of a Ferroelectric Phase-Field Model
(2019)
In this thesis, we investigate the existence and regularity results of a ferroelectric phase-field model, which is a state-of-the-art model arising in recent years from the engineering area for the ferroelectric study.

Factors Influencing the Effectivity and Usage of Desirable Difficulties in Learning
(2019-02)
What circumstantial factors or personality factors influence the effectivity of desirable difficulties, and correspondingly, the attitudes to and the usage of desirable difficulties? The dissertation covers externally regulated (laboratory and classroom) and self-regulated learning and starts with a brief introduction of the concept of desirable difficulties and a literature review of selected papers on disfluency, interleaving and spacing, as well as testing and generation. The literature review focuses on effectivity ...

Integration through Exploitation: Syrians in Turkey
(Reiner Hampp Verlag, 2019)
This book is about the largest displacement crisis and resettlement of our time. However, it is not another piece that elaborately describes the appalling situation of Syrian workers in Turkey, but explores how they are integrated into the lower ends of the value chain in several sectors. The book seeks answers of what has been largely overlooked in the literature on the question of how labor processes have been shaped in various labor-intensive sectors by class and identity.

Hybrid Branching-Time Logics
(2019)
We introduce and study an extension of the well-known and well-studied branching-time logics CTL, CTL+, FCTL+, CTL* and the modal μ-calculus with the so called "hybrid framework". This framework borrows ideas from first-order logic to enable more precise "structural" reasoning which is known to be impossible in the original logics. In particular, the extension with this framework enables these logics to uniquely name, reference and test for certain states, similarly to the concepts of variables and constants in ...

Reflexionsfähigkeit in der Lehrerbildung - eine empirische Untersuchung im Rahmen der Schulpraktika im Fach Sport
(2019-08-21)
Im Kontext der Professionalisierung angehender (Sport-)Lehrkräfte kommt der Fähigkeit zur Reflexion besondere Bedeutung zu. Für ihre Förderung stellt die Arbeit mit (Video-)Fällen eine geeignete und anerkannte Methodik dar. Die Fallarbeit kann sich sowohl auf fremde videografierte als auch auf selbst erlebte Unterrichtsereignisse beziehen. Die Schulpraktischen Studien bieten als Theorie und Praxis verbindende Veranstaltungen Gelegenheit für das Sammeln eigener Unterrichtserfahrungen. Sie stellen damit einen geeigneten ...

Using crop genetic diversity to improve resilience: Agronomic potential of evolutionary breeding under differing management systems
(2019-03)
Mainly within organic and low-input cropping systems, evolutionary breeding based on the creation of heterogeneous evolving composite cross populations (CCPs) has been gaining attention. The aim of this dissertation is to assess the agronomic potential and yield stability of wheat CCPs in comparison to pure line varieties under differing management systems.
Three winter wheat CCPs were created in the UK in 2001, based on parental varieties that were selected for either their high yield or baking quality. The baking ...

Promoting abnormal grain growth in Fe-based shape memory alloys through compositional adjustments
(2019-05-28)
Iron-based shape memory alloys are promising candidates for large-scale structural applications due to their cost efficiency and the possibility of using conventional processing routes from the steel industry. However, recently developed alloy systems like Fe–Mn–Al–Ni suffer from low recoverability if the grains do not completely cover the sample cross-section. To overcome this issue, here we show that small amounts of titanium added to Fe–Mn–Al–Ni significantly enhance abnormal grain growth due to a considerable ...

The legitimation of expulsion in development discourse. A comparative analysis of World Bank projects in sub-Saharan Africa
(2019)
Comparing examples from Kenia, Ethiopia and Nigeria, the article examines how displacement through infrastructure projects is being legitimised in development discourse. Three typical justifications are the inevitability of progress, the greater common good and property rights. They are closely linked to elements of development discourse: the transformation of geocultural differences into historical stages, Othering of allegedly backward peoples, the concept of trusteeship and the assumption of the beneficial effects ...

Numerical Simulation of Ground Water Flow in Dual Porous Media of the Karun 4 Dam (Iran) Foundation and Abutments
(2019)
Beim Bau von Staudämmen und Reservoirs in Karst, die für ihre hohe Pererverenz aufgrund von Auflösungsfehlern und Leitungen bekannt sind, besteht das vorherrschende Risiko im Wasserverlust. Der Wasserverlust durch das Fundament und die Widerlager der in den Karstgebieten errichteten Dämme führt zu erheblichen Kosten und zur Nichtproduktivität der Staudämme. Obwohl die Konstruktion eines Dichtungsschleiers die gebräuchlichste Methode zur Verringerung oder Verhinderung von Wasserverlust ist, kann sie das Problem nur ...

Informality and Labour Regulations in Ghana
(Rainer Hampp Verlag, 2019)
The book makes a major contribution to the controversy about the factors driving the persistence and expansion of the informal economy. Unlike most others studies which either take a structuralist or an actor’s choice approach to the topic, this study combines a careful assessment of the economic, social and political circumstances promoting informality with a meticulously carried out econometric analysis of the dominant characteristics of workers as well as enterprises in the informal economy
in comparison to those ...
