Dissertation
Pursuing a Developmental State Trade Agenda in a Neo-Liberal Context
(Rainer Hampp Verlag, München, Mering, 2014)
This book explains why it was possible for the Worker’s Party (PT) in Brazil and the African National Congress (ANC) in South Africa to pursue a developmental state trade policy, in spite of neoliberal constraints. The major theoretical lenses are three-fold. It applies state theory (macrolevel), policy network analysis (meso-level) and theories on political parties with emphasis on factional politics (micro-level). This book highlights the socio-political relevance of comparatively progressive policy frameworks and ...

Impact of ownership concentration and corporate governance on sustainability and stakeholder risk: An empirical Analysis of listed firms from USA, UK and Germany.
(Corporate ownership and control, 2017-03-05)
This thesis contributes to and extends the literature by observing the impact of corporate governance and different attributes of board effectiveness and firm level corporate governance mechanism on stakeholder risk. Like shareholders, stakeholders also face the agency problem and fear losing their hidden resources and efforts. This thesis defines this fear of losing resources and efforts and long-term sustainability prospects as stakeholder risk. Here, it is worthwhile to mention that this thesis also contributes ...

The interplay of sustainability and capital markets
(2023)
Humanity faces significant environmental and social challenges, e.g., climate change (UN, 2019). Those challenges are, to some extent, addressed by politics. For instance, the European Union (EU) tries to address environmental topics, such as climate change, with the EU Action Plan on Financing Sustainable Growth to steer capital flows into more sustainable business models (EU, 2018). This regulatory development, in conjunction with a surging demand for sustainable investment solutions leads to a pressing need for ...

Influence of the electronic shell structure on the elastic scattering of heavy ions
(1982)
The interatomic potential of the system I - I at intermediate and small distances is calculated from atomic DFS electron densities within a statistical model. Structures in the potential, due to the electronic shells, are investigated. Calculations of the elastic differential scattering cross section for small angles and several keV impact energies show a detailed peak pattern which can be correlated to individual electronic shell interaction.

Interatomic potential structures in highly ionized scattering systems
(1983)
The interatomic potential of the ion-atom scattering system I^N+-I at small intermediate internuclear distances is calculated for different charge states N from atomic Dirac-Focker-Slater (DFS) electron densities within a statistical model. The behaviour of the potential structures, due to ionized electronic shells, is studied by calculations of classical elastic differential scattering cross-sections.

Prediction of the azimuth angle dependence of the quasimolecular anisotropy in heavy ion collisions
(1979)
Within the quasimolecular (MO) kinematic dipole model we predict a strong dependence of the anisotropy of the MO radiation on the orientation of the heavy ion scattering plane relative to the direction of the photon detection plane.

Land tenure in a changing climate
(2023)
Climate change and extreme weather have far-reaching impacts on agriculture. They do not only affect agricultural production, but also fundamental assets that shape agricultural livelihoods. In this dissertation, I study the relation of weather and climate with agricultural land tenure in low- and middle-income countries. Secure access to land is of vital importance for farmers, but insecure tenure is a reality for millions of farmers around the globe. They are unsure whether they will be able to continue farming ...

Wissenschaftliche Begleitstudie. Sozialwirtschaft integriert "Neue Chancen in der Sozialwirtschaft - Qualifzierungsperspektive für Migrantinnen"
(2023-04)
Vor dem Hintergrund vielfacher gesellschaftspolitischer Entwicklungen zielt „Sozialwirtschaft integriert – Neue Chancen in der Sozialwirtschaft – Qualifizierungsperspektive für Migrantinnen“ (SoWi) als innovatives und zwischenzeitlich verstetigtes Projekt in der kommunalen Arbeitsförderung darauf ab, Teilhabemöglichkeiten am Arbeits- und Ausbildungsmarkt für Frauen zu eröffnen, die aufgrund ihres Migrationshintergrunds, ihrer sprachlichen Fähigkeiten sowie struktureller Barrieren mit unterschiedlichen Herausforderungen ...

Effect of Post-Process Machining on Surface Properties of Additively Manufactured H13 Tool Steel
(2018-08-28)
Der Werkzeugstahl AISI H13 zeichnet sich durch einen hohen Verschleißwiderstand und eine gute Temperaturwechselbeständigkeit aus. Hauptanwendungsbereiche des H13 sind Druckguss- und Schmiedewerkzeuge. Die Verarbeitung von H13 durch additive Fertigungsverfahren, wie z. B. dem selektiven Laserschmelzen (selective laser melting, SLM), eröffnet neue Gestaltungsmöglichkeiten, wie z. B. die Integration interner Kühlkanäle, die es erlauben, das Einsatzverhalten der Werkzeuge zu verbessern. Aufgrund hoher Oberflächenrauheiten ...

A Screening Approach for Rapid Qualitative Evaluation of Residual-Stress States – Application to Laser-Hardened Microalloyed Steel
(2019-06-11)
Surface hardening and compressive residual stresses are keys to superior part performance in numerous applications. In this context the development of advanced laser surface treatments for new materials and complex sample shapes is a time con-suming process. Eventually, determination of residual stress states by means of X-ray diffraction in the whole surface and subsurface region, respectively, is one of the main time consuming facors in terms of characterization. In many applications the provision of an adequate ...
