This dissertation studies the impacts of research and development (R&D) funding on firm performance and innovation outcomes, focusing on both targeted regional policies and broader R&D initiatives in Germany. Comprising three essays, it explores the direct and spillover effects of these policies at the firm level, using a range of empirical techniques and extensive datasets. The first essay investigates the German Leading-Edge Cluster Competition, finding significant positive effects on innov...

Introduction: Narratives are enriched by taking the perspective of the protagonists, which can be expressed using reported speech. Nevertheless, the use of reported speech is unaddressed internationally among individuals with Down syndrome. Method: Narratives of 28 children and adolescents with Down syndrome were collected using a non-verbal picture book. Occurrence and forms of reported speech were analysed and compared to typically-developing children (TD; n = 33). Results: Parti...

In manufacturing, thermomechanical processes such as static annealing and hot working are commonly used to tailor the microstructure of metals to achieve favourable macroscopic material properties that meet specific application requirements. To improve sequential manufacturing processes and to accurately predict the microstructural changes of the material along the process chain, physically motivated constitutive models are required that simultaneously account for the effects of recovery and ...

Research has shown that impression management helps entrepreneurs access critical resources, but insights into applying concrete impression management techniques in new venture recruitment remain scarce. This knowledge gap represents a challenge for new ventures facing disadvantages in recruitment. We propose self-presentations of entrepreneurial hustle as an effective impression management technique for entrepreneurs. Such self-presentations to applicants increase the perceived competence an...

Based on investment theories and guided by Mussel's (2013) intellect model, the present study investigated reciprocal relations over 1 year (2021–2022) between investment traits (need for cognition, achievement motives, epistemic curiosity) and fluid and crystallized cognitive abilities in 565 German elementary school children (298 girls; Mage = 8.40, SD = 0.59; 59.5% with immigration background). Children's fluid and crystallized abilities increased over time, whereas fear of failure and cur...

This paper examines the German system of vocational rehabilitation and participation from a system- and innovation-theoretical perspective. The German system of vocational rehabilitation and participation, with its established special systems for participation in the labor market, is facing a - long overdue - reorientation. The article presents central instruments of the vocational rehabilitation system based on legal foundations, official labor market statistics, and current research finding...

Die moderne Produktionstechnik strebt ökonomische Effizienz und Nachhaltigkeit an, ohne die Qualität der gefertigten Bauteile zu beeinträchtigen. Die Auswahl und Anpassung von Fertigungsprozessen und die damit einhergehende Erzeugung relevanter Randschichteigenschaften ist entscheidend. Der BTA-Tiefbohrprozess ist ein produktives Verfahren zur Fertigung tiefer Bohrungen mit großen Durchmessern. Das BTA-Tiefbohren ist ein wichtiger Bearbeitungsschritt für die Fertigung hochbelasteter und siche...

apsules and their properties have provoked an increasing interest in several fields of the sciences and industry. In the sciences, several relevant biological system are modeled as a liquid core encapsulated by a skin of some sort, e.g. red blood cells. In industry, capsules are usually used the other way around -- not to model nature, but rather to design for functionality, e.g. in medical application or the food industry. Given their ubiquitous application, we discuss and investigate ...

This thesis examines the employment and tax multipliers of German fiscal policy between the World Wars. Chapter 1 offers an introductory overview. Chapter 2 estimates the regional job multipliers of public job creation schemes financed by the German unemployment insurance between 1933 and 1937. The financial outlay associated with one year of employment in these programmes was found to be 706 RM, a figure that is marginally higher than the rate of unemployment benefits but represents approxim...

Die eingereichte Dissertation „Erfahrungswissen auf Reisen. Eine ethnographische Untersu-chung zum kommunikativen Umgang mit Menschen mit diagnostizierten Autismus-Spektrum-Störungen“ ist eine soziologische Ethnographie des kommunikativen Umgangs mit der medi-zinischen Kategorie Autismus-Spektrum-Störungen (kurz: ASS). Zentral geht es um die Be-antwortung der Frage, welches Wissen, welche Deutungsmuster und welche Handlungsstrate-gien involvierte Expert*innen aus den Bereichen Familie, Pflege...

The spatial-numerical association of response codes (SNARC) effect denotes faster and more accurate left responses to small(er) numbers and faster and more accurate right responses to large(r) numbers, as compared to the reverse assignment. The spatial-size association of response codes (SSARC) effect describes a similar observation for physical instead of numerical size: left responses are faster and more accurate to physically small(er) stimuli whereas right responses are faster and more ac...

Silicon carbide MOSFETs have increasingly been recognized as advantageous compared to conventional silicon IGBTs; however, they face significant challenges due to a high defect density in the raw material. To optimize semiconductor efficiency, it is critical to minimize both conduction and switching losses. Conduction losses are influenced by on-state resistance and device breakdown voltage, while switching losses are dependent on switching speed, which is constrained by turn-off voltage over...

Experiments at particle accelerators, such as the Large Hadron Collider (LHC), are at risk of damage due to the high-energy beams. The Beam Conditions Monitor protects the LHCb detector at the LHC. It measures the particle flux with diamond sensors at two positions near the interaction point. If the measured signals exceed safe levels, the BCM automatically triggers a dump of the LHC beams. The LHCb detector was upgraded from 2018 to 2022. Consequently, the BCM needed to be adapted to a f...

The here presented work is dedicated to the development of a software analysis tool specialized for Taylor bubble flows in a wide range of applications and covering a variety of geometrical realizations. Accordingly, a higher order FEM based interface tracking simulation software has been designed which due to the underlying isoparametric discretization and interface aligned mesh construction allows a semi-implicit treatment of the surface tension force term. The such designed numerical frame...
