Roman Liedtke investigates the causes of the failure of business incubators in developing countries. Based on the insights of an incubator program in Namibia, he develops a new absorptive capacity model which enables incubators in developing countries to improve their processes in order to better benefit from external resources.

Lukas Pehle beschäftigt sich mit der transienten thermischen und strukturmechanischen Analyse einer 19-stufigen Mitteldruck-Dampfturbine. Dafür errechnet und bewertet er Zeitdauern und auftretende Spannungen, um ein breites Spektrum an Vorwärm-Szenarien beschreiben zu können. Das dabei verwendete und weiterentwickelte Festkörpermodell wird an experimentellen Daten kalibriert, um im Anschluss eine Parameterstudie durchführen zu können. Mithilfe des untersuchten Konzepts des Vorwärmens von Dampfturbinen können thermisch induzierte Spannungen beim Kraftwerksstart verringert werden. Dieses Buch leistet aufgrund der dadurch flexibleren Kraftwerke einen wichtigen Beitrag zur Versorgungssicherheit nach der Energiewende, also für den Übergang von fossilen Energieträgern und der Kernenergie zu einer nachhaltigen Energieversorgung mittels erneuerbarer Energien.

Nikolas Zoeller examines the working principles and the underlying theoretical foundations of a microscopic heat engine. In particular, he investigates the system's stochastic dynamics in the underdamped regime which has hardly been studied in the past, but will be experimentally feasible in the near future due to recent technological developments.

Jochen Szangolies contributes a novel way of dealing with the problem of the experimental testability of the Kochen-Specker theorem posed by realistic, that is, noisy, measurements. Such noise spoils perfect compatibility between successive measurements, which however is a necessary requirement to test the notion of contextuality in usual approaches. To overcome this difficulty, a new, extended notion of contextuality that reduces to Kochen-Specker contextuality in the limit of perfect measurement implementations is proposed by the author, together with a scheme to test this notion experimentally. Furthermore, the behaviour of these tests under realistic noise conditions is investigated.

Matthaus Jager examines the simulation of liquid-gas flow in fuel tank systems and its application to sloshing problems. The second step involves the cell-centered finite volume method and its application to fluid dynamic problems with free surfaces using a volume of fluid approach.

Even though it is increasingly clear that the work environment can facilitate or inhibit creative behavior in organizations, there is a lack of research investigating how individual differences influence this relationship.

Anna-Lena Bunse explores the network structure of migrant entrepreneurs in Bremen-Groepelingen, and asks how informal networks for migrant entrepreneurs are structured and how migrant entrepreneurs can benefit from informal networks.

Josef Anton Strini analyzes a special stochastic optimal control problem. The problem under study arose from a dynamic cash management model in finance, where decisions about the dividend and financing policies of a firm have to be made.

Christina Maria Tonauer finds novel evidence for the first-order nature of the transition between high-density amorphous ice (HDA) and low-density amorphous ice (LDA), supporting water's liquid-liquid transition scenarios.

Maren Hagemeister examines how institutions influence foreign firms market entry decisions and subsidiary performance in Russian regions. In an empirical study the author analyses the market entries of a sample of European Union firms in the Russian federal districts between 2005 and 2013.
