• Smartphone-assisted psychoeducation in adult attention-deficit/hyperactivity disorder: A randomized controlled trial

  Selaskowski, B. (2022). Smartphone-assisted psychoeducation in adult attention-deficit/hyperactivity disorder: A randomized controlled trial. Psychiatry Research, 317, 114802. http://doi.org/https://doi.org/10.1016/j.psychres.2022.114802

  Abstract

  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.

• Real-Time control of a Modular Multilevel Converter via MATLAB/Simulink and EtherCAT fieldbus

  Fey, J.-H., Hinrichsen, F., & Mallwitz, R. (2022). Real-Time control of a Modular Multilevel Converter via MATLAB/Simulink and EtherCAT fieldbus. In 2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG) (S. 1–5). Kiel, Germany. http://doi.org/10.1109/PEDG54999.2022.9923196

  This paper shows the possibility of using standardized communication system components to shorten the development time of complex power electronics converter control. It can be seen that the combination of MATLAB/Simulink with EtherCAT fieldbus is an excellent alternative to classical microcontroller-based solutions. Investigations were carried out on a modular multilevel converter topology (MMC), which was described in [1]. The elementary demands on the communication and control system, as well as the development process from simulation to implementation, are briefly reported. Finally, the performance of the overall system will be examined and the impacts of discrete signals and propagation delay on the Total Harmonic Distortion (THD) of the output voltage are discussed.

• 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

  Abstract

  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.
