  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.

• Smartphone-assisted Psychoeducation in Adult Attention-Deficit/Hyperactivity Disorder: A Randomized Controlled Trial

  Selaskowski, B. ., Steffens, M. ., Schulze, M. ., Lingen, M. ., Aslan, B. ., Rosen, H. ., … Braun, N. . (2022). Smartphone-assisted Psychoeducation in Adult Attention-Deficit/Hyperactivity Disorder: A Randomized Controlled Trial.

  Psychoeducation is generally recommended in the treatment of adult Attention-Deficit/Hyperactivity Disorder (ADHD), but only few studies have systematically assessed the effects of structured clinical psychoeducation. Moreover, although a considerable number of psychoeducational mobile applications exist, none have provided scientific evidence for their effectiveness or safety. Therefore, the present randomized controlled trial investigated a newly developed, free-to-use psychoeducation app for adults with ADHD as a support to a clinical psychoeducation group. 236 adults with ADHD were contacted for study participation, of whom 60 were finally randomized to a psychoeducation group supported either by our developed smartphone app (n = 30) or by traditional pen-and-paper brochures (n = 30). Psychoeducation treatments were conducted in groups of 10, with 8 weekly one-hour sessions between March 2019 and November 2020. Observer-rated ADHD symptom severity (IDA-R interview) was examined as the primary outcome parameter before and after treatment. Across both interventions, ADHD core symptoms were significantly reduced. Notably, the smartphone-assisted psychoeducation was significantly more effective in improving inattention and impulsivity and led to higher homework compliance than the brochure-assisted psychoeducation. No adverse events were reported.

• 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.

• Good Tech and Social Good: Value Creation by Korean Social and High-Tech Oriented Start-Ups

  Berg, S.-H. ., & Mitra, J. . (2022). Good Tech and Social Good: Value Creation by Korean Social and High-Tech Oriented Start-Ups. Volume 8 Issue 1, 8(1), 29–45. Abgerufen von https://EconPapers.repec.org/RePEc:sae:jouent:v:8:y:2022:i:1:p:29-45

  Abstract

  Through an exploration of Korean high-tech social enterprises, we aim to identify and explore critically (a) how socially engaged, early stage, high technology firms combine social and economic objectives with which to scale up their ventures; and (b) how socially engaged firms seek entrepreneurial opportunity development, including the internationalisation process and the support of stake holding institutions to help scale up the value creation process. We highlight ‘people’, ‘organisations’ and the ‘environment’ dimensions, enabling an understanding of the drivers of socially entrepreneurial activity both from individual and societal perspectives. The analytical framework of our study is based on empirical data acquired from individual in-depth interviews, group interviews, active participatory observations and survey data from 2018 to 2021. We found that social motivation and objectives of the entrepreneurs are equally strong drivers and that they are the principal factors for the scaling up process. The motivation is strengthened by the proactive role of government initiatives which also attract other key stakeholders in the growth process. A combination of digital technology with a high degree of social motivation of the entrepreneurs tends to lead to the development of international market opportunities and attract the interests of international foundations.

• 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.

  Im Rahmen der Studie werden wirtschaftliche St arken und Schw achen beidseits der deutsch-d anischen Grenze sowie Handlungsfelder f ur eine vertiefte Kooperation in der Grenzregion identifiziert. Es wird analysiert, welche "kritischen Massen" in der Grenzregion mobilisiert werden k onnten, um auf beiden Seiten der Grenze Schw achen zu uberwinden und die Gesamtregion im Wettbewerb um Investoren und knappe Arbeitskr afte zu st arken. Auf Grundlage einer Expertenbefragung werden Schl usselfaktoren f ur die Entwicklung der Grenzregion abgeleitet und m ogliche Entwicklungsszenarien f ur die deutsch-d anische Grenzregion modelliert. Das Autorenteam zeigt dar uber hinaus, dass die Erfahrungen und Kooperationsmodelle bereits st arker integrierten Grenzregionen Lerneffekte f ur die Institutionalisierung der Zusammenarbeit und insbesondere f ur die Ausgestaltung von Arbeitsmarktkooperationen bieten. — — The study identifies economic strengths and weaknesses on both sides of the German-Danish border as well as fields of action for deeper cooperation in the border region. It analyzes which "critical masses" could be mobilized in the border region to overcome weaknesses on both sides of the border and to strengthen the overall region in the competition for investors and scarce labor. Based on an expert survey, key factors for the development of the border region are derived and possible development scenarios for the German-Danish border region are modeled. The team of authors also shows that the experiences and cooperation models of already more integrated border regions offer learning effects for the institutionalization of cooperation and especially for the design of labor market cooperation.

• LSP Teacher Training Summer School . The TRAILs project

  Abstract

  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.
