• A symbolic framework to obtain mid-fidelity models of flexible multibody systems with application to horizontal-axis wind turbines

  Branlard, E., & Geisler, J. (2022). A symbolic framework to obtain mid-fidelity models of flexible multibody systems with application to horizontal-axis wind turbines. Wind Energy Science, 7, 2351–2371. http://doi.org/10.5194/wes-7-2351-2022

  Abstract

  The article presents a symbolic framework (also called computer algebra program) that is used to obtain, in symbolic mathematical form, the linear and nonlinear equations of motion of a mid-fidelity multibody system including rigid and flexible bodies. Our approach is based on Kane's method and a nonlinear shape function representation for flexible bodies. The shape function approach does not represent the state of the art for flexible multibody dynamics but is an effective trade-off to obtain mid-fidelity models with few degrees of freedom, taking advantage of the separation of space and time. The method yields compact symbolic equations of motion with implicit account of the constraints. The general and automatic framework facilitates the creation and manipulation of models with various levels of complexity by adding or removing degrees of freedom. The symbolic treatment allows for analytical gradients and linearized equations of motion. The linear and nonlinear equations can be exported to Python code or dedicated software. There are multiple applications, such as time domain simulation, stability analyses, frequency domain analyses, advanced controller design, state observers, and digital twins. In this article, we describe the method we used to systematically generate the equations of motion of multibody systems and present the implementation of the framework using the Python package SymPy. We apply the framework to generate illustrative land-based and offshore wind turbine models. We compare our results with OpenFAST simulations and discuss the advantages and limitations of the method. The Python implementation is provided as an open-source project.

• Are greener start-ups of superior quality? The impact of environmental orientation on innovativeness, high-growth, and internationalization (PREPRINT)

  Neumann, T. (2022). Are greener start-ups of superior quality? The impact of environmental orientation on innovativeness, high-growth, and internationalization (PREPRINT). Journal of Innovation and Entrepreneurship. Abgerufen von https://doi. org/10.21203/rs.3.rs1557653/v1

  This paper merges the literature on green and high-quality entrepreneurship by introducing environmental orientation as an unrecognised characteristic of start-up quality and the three quality dimensions innovativeness, high-growth, and internationalisation. Entrepreneurship literature argues that only highquality start-ups contribute to sustainable development and that a better understanding of what determines the quality of start-ups is required. Empirical research has recently shown that the environmental orientation of start-ups is one such determinant, as it significantly predicts their innovativeness. This paper pursues this novel research avenue on the importance of environmental orientation for start-up quality in two ways. First, this paper evaluates and extends this initial evidence on environmental orientation and innovativeness by examining a three times larger sample, covering additional countries and entrepreneurial stages. Second, this paper also analyses the impact of environmental orientation on the quality dimensions of high-growth and internationalisation. Investigation using Global Entrepreneurship Monitor data on 9,650 entrepreneurs from 51 countries revealed that start-ups with a higher environmental orientation are of superior quality regarding their innovativeness, growth expectations, and exports. These results remain robust for start-ups at different entrepreneurial stages, and tests employing different methodological approaches and variable definitions. However, the categorisation into factordriven, efficiency-driven, and innovation-driven countries showed that greener start-ups are more innovative in countries at all three levels of development, while the relationships with high-growth and internationalisation remained significant for only two of the three categories. The findings of this paper provide a new approach for practitioners to identify the small number of high-quality start-ups and an economic reason warranting intensified efforts to support green start-ups.

• Tax Misperception and its Effects on Decision Making – Literature Review and Behavioral Taxpayer Response Model

  Blaufus, K., Chirvi, M., Huber, H.-P., Maiterth, R., & Sureth-Sloane, C. (2022). Tax Misperception and its Effects on Decision Making – Literature Review and Behavioral Taxpayer Response Model. European Accounting Review, 31(1). http://doi.org/10.1080/09638180.2020.1852095

  Abstract

  Previous accounting research shows that taxes affect decision making by individuals and firms. Most studies assume that agents have an accurate perception regarding their tax burden. However, there is a growing body of literature analyzing whether taxes are indeed perceived correctly. We review 128 studies on the measurement of tax misperception and its behavioral implications. The review reveals that many taxpayers have substantial tax misperceptions that lead to biased decision making. We develop a Behavioral Taxpayer Response Model on the impact of provided tax information on tax perception. Besides individual traits, characteristics of the tax information and the decision environment determine the extent of tax misperception. We discuss opportunities for future research and methodological limitations. While there is much evidence on tax misperception at the individual level, we hardly find any research at the firm level. Little is known about the real effects of managers’ tax misperception and on how tax information is strategically managed to impact stakeholders. This research gap is surprising as a large part of the accounting literature analyzes decision making and disclosure of firms. We recommend a mixed-method approach combining experiments, surveys, and archival data analyses to improve the knowledge on tax misperception and its consequences.

• LSP Teacher Training Summer School . The TRAILs project

  This book is the result of research carried out in partnership with seven European universities as part of an Erasmus+ project on training teachers of Language for Specifi c Purpose (LSP) in higher education. All university partners, i.e. Bordeaux (France), Zagreb (Croatia), Jade (Germany), Cádiz (Spain), Adam Mickiewicz (Poland), Ljubljana (Slovenia), Arcola Research (UK), and Bergamo (Italy) carried out surveys and developed a detailed report showing that in Europe there is very little training for this type of teaching, and that teachers generally need to be trained in the specifi cities of the language fi eld they are going to teach. Medical or maritime English, legal Spanish, French for tourism, etc. require both an expert domain knowledge and a grounding in language teaching. Several testimonies highlight this situation and show the lack of career development prospects for LSP teachers at European universities. The members of the Erasmus+ TRAILs project have therefore been interested in the specifi c needs of LSP teachers and have been able to update the information through several types of surveys. The competences of LSP teachers were thus identifi ed. Based on this precise inventory, they are proposing to draw up a complete training programme. A pedagogical approach has been developed: resources, lesson preparation, course design, innovative pedagogical approaches are presented. The research presented in this book goes well beyond the TRAILs project and questions the training of specialised language teachers. More generally, it highlights the need to provide effective training and professional development for LSP teachers and offers a contribution to overcoming the shortcomings of LSP teacher education.

• Planetarium Talks: Extra dimensions and microscopic black holes

  Vest, A. (2022). Planetarium Talks: Extra dimensions and microscopic black holes.

  Abstract

  Although Einstein’s general theory of relativity precisely describes the properties of gravity, it is not clear why gravity is so much weaker than the other fundamental forces of nature. The weakness of gravity could be explained, however, by speculative theories that predict spatial dimensions in addition to the three dimensions we experience in our everyday live. One spectacular way of revealing these extra dimensions would be through the formation of microscopic black holes, which, if there are extra dimensions, might be produced at the Large Hadron Collider. Microscopic black holes would be harmless, but their discovery would revolutionize our physical world picture.

• Service Learning as an Approach to Teaching Small Business Management

  Small- and medium-sized enterprises (SMEs) are a central backbone of (most) national economies. Research shows, that due to their smaller size, SMEs not only have comparatively less formalized, less complex, and less specialized organizational structures, but a somewhat different social character as well. It is in particular the interplay of these structural and cultural peculiarities of SMEs that is difficult to impart perceptibly in regular university courses on Small Business Management. From a managerial science perspective, the structural as well as social characteristics of small non-profit organizations are quite similar to the above-mentioned features of SMEs. Both types of organizations usually function in a less bureaucratic and more personal way, while also being a bit more chaotic sometimes. In addition, both are often facing the challenges of severe resource scarcity as well as a lack of management competencies. In view of these fundamental similarities between SMEs and small non-profit organizations, the practical seminar Service Learning Project was designed to provide management students at Europa-Universität Flensburg with the opportunity of experiencing typical small business work realities. Here, student teams support local non-profit organizations in meeting typical management challenges ranging from the conception and implementation of fundraising or image campaigns to internal consultancy projects. In this way, the seminar offers the possibility to deal with real-world practical management issues while concurrently strengthening students’ civic societal awareness, fostering empathy, and overcoming the oftentimes overly pronounced distance between science and life-world practice.
