A1 - Virchow, Fabian T1 - Far-right leadership in comparison: shifts and continuities in German-speaking movements JF - Social Movement Studies N2 - Leadership has long been acknowledged as a crucial feature of social movement activity. Theorisation has delved into the types of leadership and, more recently, the activities performed by leaders. However, comparative research on leadership and detection of any changes over time is scant. Our paper attends to these tasks by looking at the activities of two German-speaking far-right leaders. For many years, Christian Worch was one of the most active and influential neo-Nazi leaders in Germany, communicating much of his activity and strategy in the mid-2000s through a regular circular (Rundbriefe). Similarly, Martin Sellner, both as leader of the Identitarian movement and independent activist, today exercises an outsized role in the German-speaking far-right scene, including through his regular publications in the magazines Compact and Sezession. Our paper uses data of Worch’s and Sellner’s writings, scraped from webpages and gathered from archives, in a mixed-methods comparative design to identify the tasks performed by these leaders, and how frequently. Quantitative text analysis techniques guide the qualitative evaluation of leaders’ activities and reveal shifts – and continuities – in far-right movement leadership. The paper thereby contributes to scholarship on an important aspect of contemporary far-right movements as well as broader social movement literature on the topic of leadership.

In a theoretical model of an internationally fragmented digital good's production process, we show that fairness considerations of tax authorities (namely inequity aversion) can result in a falling apart between a perceived "fair" and arm's length distribution of profits across tax jurisdictions. Our model predicts that a multinational firm follows the fundamental paradigm of international taxation, i.e. the arm's length principle, to properly incentivize internal agents involved in the production of a digital good. However, with inequity averse tax authorities, we find that tax authorities "prefer" a more equal distribution of profits compared to the arm's length allocation. From a multinational firm's perspective, inequity aversion among tax authorities dampens the strategic effect to - in accordance with arm's length principle - shift profits to low tax countries. N2 - Die OECD Base Erosion Profit Shifting (BEPS) Initiative sowie die aktuelle Fairness orientierte öffentliche Diskussion zur Besteuerung digitaler Geschäftsmodelle verdeutlichen die Bedeutung und Komplexität des Fremdvergleichsgrundsatzes. Wir modellieren einen international fragmentierten Produktionsprozess eines digitalen Gutes und zeigen wie Fairness-Erwägungen von Steuerbehörden (d.h. Ungleichheitsaversion) dazu führen kann, dass die als "fair" wahrgenommene und die zum Fremdvergleichsgrundsatz konforme Gewinnverteilung innerhalb der Steuerjurisdiktionen auseinander fällt. Unser Modell sagt voraus, dass eines multinationales Unternehmen dem fundamentalen Paradigma der internationalen Besteuerung, d.h. dem Fremdvergleichsgrundsatz folgt, um firmenintern effiziente Anreize zur Produktion des digitalen Gutes zu setzen. Ungleichheitsaversion auf Seiten der Steuerbehörden führt allerdings dazu, dass die Steuerbehörden eine gleichmäßigere Verteilung der Gewinne im Vergleich zum Fremdvergleichsgrundsatz bevorzugen. Aus Sicht eines multinationalen Unternehmens dämpft die Ungleichheitsaversion der Steuerbehörden den strategischen Anreiz Gewinne in Niedrigsteuerländer zu verlagern.

T1 - Extracting Production Style Features of Educational Videos with Deep Learning T2 - Proceedings of DELFI Workshops 2022 Karlsruhe, 12. September 2022 N2 - Enforced by the pandemic, the production of videos in educational settings and their availability on learning platforms allow new forms of video-based learning. This has a strong benefit of covering multiple topics with different design styles and facilitating the learning experience. Consequently, research interest in video-based learning has increased remarkably, with many studies focusing on examining the diverse visual properties of videos and their impact on learner engagement and knowledge gain. However, manually analysing educational videos to collect metadata and to classify videos for quality assessment is a time-consuming activity. In this paper, we address the problem of automatic video feature extraction related to video production design. To this end, we introduce a novel use case for object detection models to recognize the human embodiment and the type of teaching media used in the video. The results obtained on a small-scale custom dataset show the potential of deep learning models for visual video analysis. This will allow for future use in developing an automatic video assessment system to reduce the workload for teachers and researchers.

Therefore, we conducted a study based on the Experience Sampling Method to measure the relative contribution of a broad range of potentially relevant acoustic and non‐auditory variables in predicting indoor soundscape evaluations. Here we present the comprehensive dataset for which 105 participants reported temporally (rather) stable trait variables such as noise sensitivity, trait affect, and quality of life. They rated 6.594 situations regarding the soundscape standard dimensions, perceived loudness, and the saliency of its sound components and evaluated situational variables such as state affect, perceived control, activity, and location. To complement these subject‐centered data, we additionally crowdsourced object‐centered data by having participants make binaural measurements of each indoor soundscape at their homes using a low‐(self‐)noise recorder. These recordings were used to compute (psycho‐)acoustical indices such as the energetically averaged loudness level, the A‐weighted energetically averaged equivalent continuous sound pressure level, and the A‐weighted five‐percent exceedance level. This complex hierarchical data can be used to investigate time‐varying non‐auditory influences on sound perception and to develop soundscape indicators based on the binaural recordings to predict soundscape evaluations.

However, despite significant efforts to optimize SCPP design, their efficiency and power generation capabilities remain limited. Researchers have explored modifications in plant geometry and hybridization to improve efficiency. Despite extensive work in this area, commercialization of SCPPs has not yet been achieved. Most of the research is numerical and may differ from real-world practical use. The number of experimental studies is also relatively small. To facilitate commercialization, further investigation with practical and feasible dimensions is required. This comprehensive review paper aims to provide an in-depth analysis of experimental approaches and advancements in the field of SCPPs. The paper begins with an introduction, highlighting the background, significance, and objectives of the review. It provides an overview of the plants, discussing their principles and operation as innovative renewable energy systems. The historical development and evolution of solar chimneys are explored, shedding light on their progression over time. Case studies of operational hybrid SCPPs are examined to showcase real-world applications and performance. The paper also addresses environmental impacts and sustainability considerations associated with SCPPs. Furthermore, recommendations for future research and development in this field are provided to guide researchers and industry professionals. This study focuses on the possibility of commercialization of both standalone and hybrid SCPPs.

Measurements were conducted for a total number of 38 orifices, covering a wide range of length-to-diameter ratios, including short and long orifices with varying inlet geometries. Up to five different chamfer-to-diameter and radius-to-diameter ratios were tested per orifice length. Furthermore, the static pressure ratio across the orifice was varied between 1.05 and 1.6 for all examined orifices. The results of this comprehensive investigation demonstrate the beneficial influence of rounded inlet geometries and the ability to decrease pressure losses, which is especially true for higher cross flow ratios where the reduction of the pressure loss in comparison to sharp-edged holes can be as high as 54%. With some exceptions, the chamfered orifices show a similar behavior as the rounded ones but with generally lower discharge coefficients. Nevertheless, a chamfered inlet yields lower pressure losses than a sharp-edged inlet. The obtained experimental data were used to develop two correlations for the discharge coefficient as a function of geometrical as well as flow properties.

A CORC is set up and initially tested with cyclopentane and propane as working fluids in its high temperature and low temperature cycle, respectively. A thermal oil cycle serves as the heat source and is powered electrically with a maximum heat flow of 158 kW. The design of this experimental setup allows for a rapid replacement of individual components and for a wide range of conditions in terms of fluids and thermodynamic states. The components of all cycles and the measurement and control technology are described in detail. A testing procedure is presented, followed by a discussion of the measurement results, where it is shown that the intended concept of two cascaded organic Rankine cycles is operational and that the measured data are consistent.

The most promising concepts are Organic Rankine Cycles (ORC) and Steam Rankine Cycles (SRC). In previous work of the Center of Innovative Energy Systems, Düsseldorf (Germany), the technical and economic feasibility of a low pressure SRC has been investigated and the advantages in comparison to organic Rankine cycles are highlighted. A distinctive feature of the cycle is the use of the ICE coolant heat for evaporation, which limits the cycles maximum steam pressure to values below atmospheric pressure. This work presents first results of a test rig with data reconciliation according to DIN 2048 to validate the simulation results and design calculations. As a basis for the experimental investigations, a gas fired CHP plant was selected. The design of the test rig is optimized for the operation in the laboratory, where the coolant heat is emulated by a tempering device and the exhaust heat of the CHP plant is emulated by a gas burner. With the designed test rig, it is possible to control the volume flow and the temperatures of the coolant and exhaust gas, so that different load conditions of the gas fired CHP plant can be investigated. For initial tests, the turbine in the SRC is replaced by a throttle to achieve the pressure drop of the turbine. The experimental results show, that the exhaust and coolant heat of a 36 kWel CHP plant can be emulated and the performance expectations of the cycle can be met in stable steady-state conditions. Based on the measurement results and the turbine design calculations an electric power output of the cycle of 3.8 kW will be possible, which results in a cycle efficiency of about 6.5 % and an increase of the electrical power output of the CHP plant of about 10 %. The results show that the plant concept is technically feasible and, with further optimization, also represents an alternative to ORC plants in terms of increasing the efficiency of a cogeneration plant.

Thus far, no study has been dedicated to design and experimentally implement a shell and tube concept for DPEC with an innovative configuration that can contribute in mass production, globalization, and effortless maintenance of such a high performance cooling machine. Therefore, in this paper, the shell and tube concept has been employed as a core design for DPEC that has been reinforced by a practical approaches. The practical approaches include a dedicated novel design for the proposed system and utilizing super cheap materials for the system’s construction. Both of the aforementioned approaches provide solutions for overcoming the aforementioned issues. In the meanwhile, the superiority of the proposed DPEC has been approved by comparing it to the flat plate DPEC. During the experimentations, the prototype was able to reduce the ambient temperature by up to 34.1°C (from 53°C to 18.9°C), besides, it could achieve a dew-point effectiveness of 99.6% and wet-bulb effectiveness of 135%.

In this context, perceived safety plays a critical role in their acceptance and implementation. Previous research had focused more on data security or specific digital technologies. There has also been a lack of participatory approaches to consider and empower healthcare recipients (and relatives), providers, and technology experts to broaden the phenomenon. Objective The aim of this study was to present a comprehensive perspective on the needs, influencing factors and related outcomes in the context of feeling safe with digital technologies in healthcare. Method A qualitative, exploratory, and participatory methodology was used with five guide-based focus group workshops. Each workshop explored one of five digital technology demonstrations provided at the beginning: (1) electronic health records (EHR), (2) robotics, (3) artificial intelligence (AI), (4) smart home, and (5) smart hospital. All participants were invited for a guide-based discussion. The study focused on the levels of ‘involvement’ and ‘collaboration’ by also empowering participation. The workshop target groups were actively involved in the development and execution of the workshops and were empowered. The data were analysed via a content analysis approach, with a mostly inductive procedure. Results Feeling safe was found to affect thoughts, emotions, and actions. For example, a higher level of perceived safety increased the acceptance of digital technologies, whereas a lower level of perceived safety decreased it. The corresponding needs and influencing factors differed in terms of their scope and focus depending on the context. The aspect of ‘control’ was most frequently addressed by all the target groups and was viewed as relevant in all the workshops. In general, digital technologies were viewed as supplements rather than substitutes for healthcare providers. Conclusion This study extends beyond the current state of research on perceived safety and the use of digital technologies in healthcare by providing a comprehensive overview of the corresponding needs and influencing factors at various levels, such as the individual, community-organizational, and system-society levels. The perceived safety of healthcare recipients and providers related to digital technologies should be taken into consideration to achieve positive implementation outcomes. N2 - Hintergrund Digitale Technologien werden im Gesundheitswesen immer häufiger eingesetzt. Hierbei spielt die wahrgenommene Sicherheit eine entscheidende Rolle für deren Implementierung. Bisherige Forschung konzentrierte sich eher auf die Datensicherheit oder auf spezifische digitale Technologien. Es fehlte ein partizipativer Ansatz, der es Leistungsempfangenden (deren Angehörigen), Leistungserbringenden und Technologieexpert:innen ermöglichte, die Sicht auf das Phänomen zu erweitern. Ziel Ziel war es daher erfahrungsbasiert Bedürfnisse, Einflussfaktoren und damit verbundenen Outcomes im Kontext des Sicherheitsgefühls digitaler Technologien im Gesundheitswesen zu erforschen. Methode Es wurde ein qualitatives, exploratives und partizipatives Design, basierend auf fünf leitfadengestützten Fokus-Gruppenworkshops durchgeführt. Eine von fünf digitalen Technologien ((1) elektronische Gesundheitsakten (EHR), (2) Robotik, (3) künstliche Intelligenz (AI), (4) Smart Home und (5) Smart Hospital), wurde zu Beginn oder während des Workshops vorgestellt und/oder konnte ausprobiert werden. Alle Teilnehmenden wurden zu einer leitfadengestützten Diskussion eingeladen. Die Partizipation wurde auf den Ebenen der „Beteiligung“ und „Zusammenarbeit“ gefördert, indem aktiv in die Entwicklung und Durchführung der Workshops einbezogen sowie zur Teilnahme befähigt wurde. Die Daten wurden mit Hilfe induktiver Inhaltsanalyse ausgewertet. Ergebnisse Das Gefühl der Sicherheit beeinflusst Gedanken, Gefühle und Handlungen. Beispielsweise kann ein höheres Maß an gefühlter Sicherheit die Akzeptanz digitaler Technologien erhöhen, während ein niedrigeres Maß diese verringern kann. Entsprechende Bedürfnisse und Einflussfaktoren unterschieden sich je nach Kontext in ihrem Umfang und Schwerpunkt. Der Aspekt der „Kontrolle“ wurde von allen Zielgruppen am häufigsten angesprochen und in allen Workshops als relevant angesehen. Digitale Technologien wurden eher als Ergänzung, denn als ein Ersatz für Leistungserbringende betrachtet. Schlussfolgerung Diese Studie geht über den aktuellen Stand der Forschung im Kontext wahrgenommener Sicherheit und digitaler Technologien im Gesundheitswesen hinaus, indem sie einen umfassenden Überblick über die Bedürfnisse und Einflussfaktoren von der individuellen bis hin zur System-/Gesellschaftsebene gibt. Die gefühlte Sicherheit sollte grundsätzlich berücksichtigt werden, um die Implementierung digitaler Technologien zu fördern.

These environments were characterized by large concentrations of biogenic volatile organic compounds (BVOC) and low nitrogen oxide concentration. In isoprene-dominated environments, models developed to simulate atmospheric photochemistry generally underestimated the observed OH radical concentrations. In contrast, HO2 radical concentration showed large discrepancies with model simulations mainly in non-isoprene-dominated forested environments. An abundant BVOC emitted by lodgepole and ponderosa pines is 2-methyl-3-butene-2-ol (MBO), observed in large concentrations for studies where the HO2 concentration was poorly described by model simulations. In this work, the photooxidation of MBO by OH was investigated for NO concentrations lower than 200 pptv in the atmospheric simulation chamber SAPHIR at Forschungszentrum Jülich. Measurements of OH and HO2 radicals, OH reactivity (kOH), MBO, OH precursors, and organic products (acetone and formaldehyde) were used to test our current understanding of the OH-oxidation mechanisms for MBO by comparing measurements with model calculations. All the measured trace gases agreed well with the model results (within 15 %) indicating a well understood mechanism for the MBO oxidation by OH. Therefore, the oxidation of MBO cannot contribute to reconciling the unexplained high OH and HO2 radical concentrations found in previous field studies.

T1 - Evaluation of mount loads in dynamic testing of a jet engine JF - Mechanical Systems and Signal Processing N2 - In the dynamic testing of jet engines the evaluation of loads on the mount structure is vital for comparison with finite element calculations of such testing. Measuring these loads with the help of strain gauges applied to the structure becomes difficult if the mount is overdetermined and thus not every strain gauge can be assigned to a single load direction. In this study, the overdetermined mount structure of the BR715 engine was examined at one of the three mounting points between the Boeing 717 airframe and the engine, where loads in five directions were reacted. Firstly, the dependence of five measured strains upon known static load conditions at the mounting point had to be determined. For this purpose a static calibration test was carried out where defined forces and moments in known directions were applied to the structure while the output from five strain gauges was measured accordingly. The result was the desired relationship between loads and strains in terms of a matrix, which yields the corresponding load condition of the examined mounting point if multiplied with a set of strains. The same calibration procedure was carried out with a finite element model of the mount, where direct comparison to dynamic load results from the model itself was possible. With this model the validity of the above method was shown as well as possible errors which may occur while evaluating dynamic test results. The method was found to give satisfactory results even for dynamic loading, although some inertia forces disturb the signals in dynamic testing. Finally, the results from an actual dynamic engine test were processed into loads and then compared to the simulated loads from a finite element model of the engine. Good agreement was found and the indication of any remaining discrepancies was used to update the model for an even better representation of the dynamic test loads.

Therefore, the introduction of traffic restricted or traffic reduced areas is discussed as a countermeasure in several towns. However, at that point it is not always clear, in what extent the restriction of traffic in presently overloaded streets causes the exceeding of limit values in other areas of the town after the redirection of the traffic. Presently this cannot be recorded appropriately, when the concentrations of fine particulate matter are monitored only at rarely distributed single points by the official measurement systems of the environmental state agencies. On the other hand, meanwhile there are low cost and mid cost sensors for the measurement of fine particulate matter available, which enable the parallel monitoring with many measurement systems in an extended area of the town. By this way, the effect of traffic restrictions on the distribution of fine particulate matter in the city can potentially be observed. However, at this point the question arises, how reliable the results are, which are delivered by the low and mid cost sensors for fine particulate matter. For this reason different low cost and mid cost sensors have been evaluated for this study and intercompared with certified reference measurement systems for fine particulate matter. The study comprised the sensors SDS011 (Nova Fitness), which is in use already for several citizen science projects in Germany, SPS30 (Sensirion), OPC-R1 (Alphasense), OPC-N2 (Alphasense) and OPC-N3 (Alphasense). This study was performed at urban sites in Düsseldorf (Germany) for several weeks and covered different traffic loads and different meteorological situations, in order to get representative results. As atmospheric humidity can influence the measurement results, the humidity was measured in parallel to the fine particulate matter. It could be shown that the validity of the measurement results of fine particulate matter could be improved, when the parallel readings of the humidity were taken into account.

T1 - Enhancing Perspicuity of Objects in Virtual Reality Environments T2 - Proceedings, Second International Conference on Cognitive Technology N2 - In an information-rich Virtual Reality (VR) environment, the user is immersed in a world containing many objects providing that information. Given the finite computational resources of any computer system, optimization is required to ensure that the most important information is presented to the user as clearly as possible and in a timely fashion. In particular, what is desired are means whereby the perspicuity of an object may be enhanced when appropriate. An object becomes more perspicuous when the information it provides to the user becomes more readily apparent. Additionally, if a particular object provides high-priority information, it would be advantageous to make that object obtrusive as well as highly perspicuous. An object becomes more obtrusive if it draws attention to itself (or equivalently, if it is hard to ignore). This paper describes a technique whereby objects may dynamically adapt their representation in a user's environment according to a dynamic priority evaluation of the information each object provides. The three components of our approach are: - an information manager that evaluates object information priority, - an enhancement manager that tabulates rendering features associated with increasing object perspicuity and obtrusion as a function of priority, and - a resource manager that assigns available object rendering resources according to features indicated by the enhancement manager for the priority set for each object by the information manager. We consider resources like visual space (pixels), sound spatialization channels (mixels), MIDI/audio channels, and processing power, and discuss our approach applied to different applications. Assigned object rendering features are implemented locally at the object level (e.g., object facing the user using the billboard node in VRML 2.0) or globally, using helper applications (e.g., active spotlights, semi-automatic cameras).

T1 - Enhanced prediction of heat transfer in jet impingement cooling using an artificial intelligence: A case study JF - Case Studies in Thermal Engineering N2 - This paper is about the gas turbine cooling model using the extended jet array. The aim of the present study is to explain the effect of the impinging jet configuration of elongated jet holes on the heat transfer distribution with a deep Convolutional Neural Network (CNN). CNNs preserve spatial relationships through convolutional operations—unlike traditional Artificial Neural Networks (ANNs), which require flattening of input data—allowing for higher accuracy with smaller datasets and faster training due to fewer trainable parameters. The goal is to understand how accurate and fast deep learning models with limited data can deliver predictions for complex systems such as jet impingement cooling. The proposed CNN model was compared with the numerical and experimental data. Jet impingement cooling was examined with four different Reynolds numbers (16250, 21700, 27100, 36250) and six dimensionless gaps between the jet and the target surface (G/D = 1, 2, 3, 4, 5, and 6). Mean and local Nusselt number (Nu) distributions were investigated in particular. G/D = 2 was selected as the test data for the model among the configurations. While the CFD model failed to identify this peak performance point, the CNN model accurately captured this maximum behavior despite being trained only on other configurations. Moreover, the CNN model demonstrated more suitable prediction accuracy in the first two jet impingement regions than the CFD data, especially in capturing peak Nusselt numbers and localized hot spots. It has been determined that the CNN model provided more accurate predictions of the local Nusselt numbers within the measurement region compared to the Computational Fluid Dynamics (CFD) study for the average Nu, the proposed CNN model showed a closer agreement to experimental data than numerical simulation by 4.15 % at the Re = 32500 and G/D = 2.

Using CuO–H2O nanofluid in a bottom-heated channel with circular expansion, we examine the complex interactions between forced convection, magnetic fields, and uoyancy effects. Through systematic numerical analysis, we explore the combined influences of Rayleigh, Reynolds, and Hartmann numbers on thermal performance. Our findings reveal significant heat transfer enhancement (up to 137 %) under optimal conditions, particularly with vertical magnetic field orientation at Re = 100 and Ha = 30. The results demonstrate how adiabatic blocks modify flow structures, with larger blocks diminishing vortex intensity while elevated Ra generates secondary vortices that interact with primary circulations. Magnetic field effects show notable dependence on orientation, with vertical fields generally promoting better heat transfer than horizontal configurations. To complement the numerical analysis, we develop a predictive model using Artificial Neural Network (ANN) for Nusselt numbers across various operating conditions, achieving over 99 % accuracy. The integrated computational-ANN approach offers significant advancements in optimizing thermal systems in various areas, ranging from electronics cooling to microfluidic devices.

The idea is to go beyond teaching the standards of academic writing and skills for working with scientific publications. By using a learner-centered approach, we get the students engaged in typical activities around an active attendance of a real conference. They write a paper complying with common academic standards, submit the paper and review submissions of their fellow students. Students also produce a poster and have to defend it in a poster session held publicly on campus. In this article, we present our rationale to develop the course and our results from the first semester teaching this course. This includes the presentation of useful resources for teaching and organizing scientific publishing as well as our reflected learning experience regarding the student's understanding of significance for scientific publishing.

N2 - The incorporation of new technology into existing human activities can be challenging. Numerous models have been proposed in human-computer interaction (HCI) to guide research and analyze effects. However, bridging the gap between experimental data and real-world applications often proves to be difficult. In the last decades, post-cognitivistic approaches have been developed to explain human cognition and the relation between humans and their environment. In this paper, we present a novel framework to systematically describe and analyze challenges in the context of HCI from multiple perspectives. It extends Cultural-Historical Activity Theory (CHAT) and is enriched by contemporary philosophical perspectives (enactivism, pattern theory of self and post-phenomenology).

However, the impact of perceived safety on the future of digital transformation has not been fully elucidated. To investigate perceived safety in the context of the digital transformation of healthcare while considering relevant needs, influencing factors and impacts, including crisis events, to provide recommendations for action based on a participatory, multiperspective, strategic 5-year foresight viewpoint. A strategic foresight study is conducted via a participatory mixed-methods design to understand the present related factors that are likely to be relevant to future developments in the digital transformation of healthcare.ResultsWe observed that feeling safe plays a complex role in the digital transformation of healthcare. How perceived safety is considered has and will continue to impact the individual, organisational and system levels. Regarding a potential crisis event, controversial consequences have been observed. At its core, digital (health) literacy related to equity of access and human support is one of the crucial aspects in the context of perceived safety related to the successful implementation of digital technologies in healthcare. The scenarios showed that a continuation of the current situation over the next 5 years may result in partly desirable and partly undesirable outcomes. Concrete key factors should be used in practice to support both education and healthcare quality development and research. The essence of the scenarios should serve as a starting point for research agenda setting and political decision-making in the future. However, additional research is needed to quantify the correlations among the relevant factors.

We aimed to gain comprehensive insight into needs, influencing factors and outcomes in the context of perceived safety and digital technologies in healthcare. We employed a participatory, design ethnographic research approach with 16 participants in 10 use cases. The methods included in an iterative process were, think-aloud, guideline-based interviews, process mapping, storyboard creation, and photo documentation. A qualitative, primarily inductive data analysis and synthesis was performed. Perceived safety is influenced by various factors and unmet needs. Increased perceived safety can positively support the use of digital technologies, whereas low perceived safety can limit or even hinder its use. The needs of the different target groups should be considered throughout the entire process of digital technology development and healthcare provision to support their implementation. These findings support further research by providing specific aspects of emotional and psychological safety regarding target groups, settings, and ages and those with different levels of affinity for digital technologies.

A1 - Käs, Josef T1 - Emergent complexity of the cytoskeleton: from single filaments to tissue JF - Advances in Physics N2 - Despite their overwhelming complexity, living cells display a high degree of internal mechanical and functional organization which can largely be attributed to the intracellular biopolymer scaffold, the cytoskeleton. Being a very complex system far from thermodynamic equilibrium, the cytoskeleton's ability to organize is at the same time challenging and fascinating. The extensive amounts of frequently interacting cellular building blocks and their inherent multifunctionality permits highly adaptive behavior and obstructs a purely reductionist approach. Nevertheless (and despite the field's relative novelty), the physics approach has already proved to be extremely successful in revealing very fundamental concepts of cytoskeleton organization and behavior. This review aims at introducing the physics of the cytoskeleton ranging from single biopolymer filaments to multicellular organisms. Throughout this wide range of phenomena, the focus is set on the intertwined nature of the different physical scales (levels of complexity) that give rise to numerous emergent properties by means of self-organization or self-assembly.

This assumption was tested in an experiment using a dual-task paradigm with a visual primary task and an auditory secondary task. Results showed that participants' noise sensitivity was positively correlated with mental effort. Furthermore, mental effort mediated the effect of noise sensitivity on loudness and unpleasantness ratings. The results thus support the idea that noise sensitivity is related to increased mental effort and difficulties in filtering auditory information and that situational factors should be considered.

Parent training is an effective treatment for these children and there is growing interest in the effects of parent-administered interventions with minimal therapist contact. This randomized controlled study examined the efficacy of a telephone-assisted parent-administered behavioural intervention (bibliotherapy) in families with preschool children with externalizing problem behaviour. Families were randomly assigned to a treatment group (n = 26) and an untreated waitlist control group (n = 22). The intervention comprised the reading of an 11 chapter self-help book and 11 weekly telephone consultations. Compared to the control group, the treatment group demonstrated significant decreases in parent-reported externalizing and internalizing child problem behaviour and dysfunctional parenting practices. Moreover, treated parents reported less parenting-related strains and decreases in parental depression, anxiety, and stress. The results suggest that telephone-assisted self-administered parent training is an effective alternative to more intensive forms of behavioural family intervention for preschool children with externalizing problem behaviour.

T1 - Effective data visualization strategies in untargeted metabolomics JF - Natural Product Reports N2 - LC-MS/MS-based untargeted metabolomics is a rapidly developing research field spawning increasing numbers of computational metabolomics tools assisting researchers with their complex data processing, analysis, and interpretation tasks. In this article, we review the entire untargeted metabolomics workflow from the perspective of information visualization, visual analytics and visual data integration. Data visualization is a crucial step at every stage of the metabolomics workflow, where it provides core components of data inspection, evaluation, and sharing capabilities. However, due to the large number of available data analysis tools and corresponding visualization components, it is hard for both users and developers to get an overview of what is already available and which tools are suitable for their analysis. In addition, there is little cross-pollination between the fields of data visualization and metabolomics, leaving visual tools to be designed in a secondary and mostly ad hoc fashion. With this review, we aim to bridge the gap between the fields of untargeted metabolomics and data visualization. First, we introduce data visualization to the untargeted metabolomics field as a topic worthy of its own dedicated research, and provide a primer on cutting-edge visualization research into data visualization for both researchers as well as developers active in metabolomics. We extend this primer with a discussion of best practices for data visualization as they have emerged from data visualization studies. Second, we provide a practical roadmap to the visual tool landscape and its use within the untargeted metabolomics field. Here, for several computational analysis stages within the untargeted metabolomics workflow, we provide an overview of commonly used visual strategies with practical examples. In this context, we will also outline promising areas for further research and development. We end the review with a set of recommendations for developers and users on how to make the best use of visualizations for more effective and transparent communication of results.

We investigate the dynamics of the stabilizing cap through in vitro reconstitution of microtubule dynamics in contact with microfabricated barriers, using the plus-end binding protein GFP-EB3 as a marker for the nucleotide state of the tip. The interaction of growing microtubules with steric objects is known to slow down microtubule growth and accelerate catastrophes. We show that the lifetime distributions of stalled microtubules, as well as the corresponding lifetime distributions of freely growing microtubules, can be fully described with a simple phenomenological 1D model based on noisy microtubule growth and a single EB3-dependent hydrolysis rate. This same model is furthermore capable of explaining both the previously reported mild catastrophe dependence on microtubule growth rates and the catastrophe statistics during tubulin washout experiments.

While static sound sources, such as loudspeakers, have a relatively consistent acoustic footprint, dynamic sources present a multi-faceted set of challenges. Musical instruments, for example, have dynamic radiation patterns. The directivity of these instruments changes not only with frequency, but also with the specific note being played, and with the performer's gestures. These dynamic effects of directivity influences both the perceived loudness and the timbre at a given location within the audience and shapes the spatial characteristics of the sound field produced. This modulation is crucial when recreating authentic acoustic environments, whether in a virtual environment or in real-world architectural designs. Essentially, for an acoustic simulation to be considered accurate, it must capture these nuances. The intricate interplay of directivity, pitch and motion significantly shapes the listening experience and requires deeper integration of these elements into future simulations and designs. N2 - Die computergestützte Akustiksimulation ist zu einem wichtigen Instrument für die Gestaltung verschiedener akustischer Umgebungen geworden. Das Verständnis der komplexen Abstrahlungsmuster, insbesondere von natürlichen Quellen wie Musikinstrumenten oder menschlichen Stimmen, ist dabei von entscheidender Bedeutung. Während statische Schallquellen, wie z. B. Lautsprecher, einen relativ konsistenten akustischen Fußabdruck haben, stellen dynamische Quellen eine Reihe von Herausforderungen dar. Musikinstrumente zum Beispiel haben dynamische Abstrahlungsmuster. Die Richtwirk- ung dieser Instrumente ändert sich nicht nur mit der Frequenz, sondern auch mit der gespielten Note und mit den Gesten der Interpret*innen. Diese dynamischen Effekte der Richtcharakteristik beeinflussen sowohl die wahrgenommene Lautstärke als auch die Klangfarbe an einem bestimmten Ort im Publikum und formen die räumlichen Eigenschaften des erzeugten Klangfeldes. Diese Modulation ist entscheidend für die Nachbildung authentischer akustischer Umgebungen, sei es in einer virtuellen Umgebung oder in realen architektonischen Designs. Damit eine akustische Simulation als akkurat gelten kann, muss sie diese Nuancen erfassen. Das komplexe Zusammenspiel von Richtwirkung, Tonhöhe und Bewegung prägt signifikant das Hörerlebnis und erfordert eine tiefere Integration dieser Elemente in künftige Simulationen und Designs.

JF - Social Inclusion N2 - Poor young people more often face health difficulties, (learning) disabilities, and are overrepresented in special schools. Consequently, youth from poor households disproportionately frequently participate in disability‐specific programs aiming to improve their educational levels and labor market opportunities. They face a double burden of disability and poverty. In our study, we look at poor and non‐poor youth with disabilities (YPWD) who participate in vocational rehabilitation (VR) and whether VR helps them (a) in transitioning into employment and (b) in leaving poverty. We examine the association between the receipt of initial basic income support (BIS) as a poverty indicator, later labor market outcomes, and earned vocational qualification using administrative data. We make use of a sample of all persons accepted for VR in 2010 (N = 36,645). We employ logit models on VR attendees’ labor market outcomes three and five years after being accepted for VR as well as on their earned vocational qualifications. Beside initial poverty status, we control for educational level, type, and degree of disability and program pattern during the VR process. Our findings show that YPWD from poor households have a decreased likelihood of a vocational certificate and employment. Additionally, they are more likely to receive BIS than young people not from poor households and thus more likely to remain poor. In conclusion, VR seems to support poor YPWD less in their school‐to‐work transitions. Thus, disability‐specific programs should be more tailored to the social situations of participants, and counsellors should be more sensitive to their social backgrounds.

[Vortrag] T2 - Fortschritte der Akustik - DAGA 2024, 18. - 21. März 2024, Hannover N2 - Noise sensitivity is a widely used, yet inconsistently defined, concept of being disturbed by environmental noise, independent of loudness levels. The origins of noise sensitivity are mostly unclear, but it has a higher prevalence among people with attention deficit hyperactivity disorder and autism, and could be caused by increased neural excitation due to sound, resulting in increased cognitive load. In this case, noise sensitivity can be expected to decrease people’s mental performance in both auditory and non-auditory tasks. The former was tested in an experiment using a dual-task paradigm where participants had to solve a visual task in the presence of environmental sounds and afterwards had to recall which sounds they perceived and to evaluate the overall soundscape pleasantness and loudness. Preliminary results indicate that participants’ noise sensitivity is positively correlated with the experienced cognitive load as well as with loudness and unpleasantness judgments. Also, noise sensitivity was negatively associated with the performance in the recall task and the test-retest-reliability of their judgments. These findings support the idea that noise sensitivity is a consequence of difficulties in filtering irrelevant auditory information. Y1 - 2024 PB - Deutsche Gesellschaft für Akustik e.V.

DS2-SbPG integrates potential games and Stackelberg games, which improves the cooperative trade-off capabilities of potential games and the multi-objective optimization handling by Stackelberg games. Notably, all training procedures remain conducted in a fully distributed manner. DS2-SbPG offers a promising solution to finding optimal trade-offs between objectives by eliminating the complexities of setting up combined objective optimization functions for individual players in self- learning domains, particularly in real-world industrial settings with diverse and numerous objectives between the sub-systems. We further prove that DS2-SbPG constitutes a dynamic potential game that results in corresponding converge guarantees. Experimental validation conducted on a laboratory-scale testbed highlights the efficacy of DS2-SbPG and its two variants, such as DS2-SbPG for single-leader-follower and Stack DS2-SbPG for multi-leader-follower. The results show significant reductions in power consumption and improvements in overall performance, which signals the potential of DS2-SbPG in real-world applications.
