This paper highlights publics that present themselves as counterpublics but which in actual fact reinforce existing hierarchies, particularly patriarchal structures. The case study of Girl Defined Ministries, a fundamentalist evangelical influencer duo based in Texas, links the research fields of digital religion and anti-feminist defensive publics, revealing parts of anti-feminism online that have hitherto been the reserve of digital religion studies. A consideration of the national history and religious developments of recent decades in the United States allows for a deeper understanding of this type of religious influencer. Girl Defined post content about their concept of “Biblical womanhood” on multiple platforms. In the present study, 56 blog articles by Girl Defined were analysed using qualitative content analysis through the analytical lens of the Social Identity model of Deindividuation Effects (SIDE), which reflects on how group identity is formed by simultaneously enhancing in-group and devaluing out-group norms. The findings demonstrate that Girl Defined portray the out-group, feminism, as an anti-God ideology responsible for the collective misery of women in Western societies, and hold women responsible for their own discontent by choosing the wrong path. Girl Defined therefore promote their in-group values, gender roles for women defined by God, and submission to men as the only way to live a joyful life. Presenting themselves as a persecuted and ostracised counterpublic to a feminist mainstream is central to Girl Defined’s argument. The paper adds to the existing literature on women anti-feminist and religious influencers as a development of mediatization.

Music streaming services have changed how music is played and perceived, but also how it is managed by individuals. Voice interfaces to such services are becoming increasingly common, for example through voice assistants on mobile and smart devices, and have the potential to further change personal music management by introducing new beneficial features and new challenges. Method. To explore the implications of voice assistants for personal music listening and management we surveyed 248 participants online and in a lab setting to investigate (a) in which situations people use voice assistants to play music, (b) how the situations compare to established activities common during non-voice assistant music listening, and (c) what kinds of commands they use. Analysis. We categorised 653 situations of voice assistant use, which reflect differences to non-voice assistant music listening, and established 11 command types, which mostly reflect finding or refinding activities but also indicate keeping and organisation activities. Results. Voice assistants have some benefits for music listening and personal music management, but also a notable lack of support for traditional personal information management activities, like browsing, that are common when managing music. Conclusion. Having characterised the use of voice assistants to play music, we consider their role in personal music management and make suggestions for improved design and future research.

However, before being fully implemented in the national building codes and international standards, the ZEB concept requires clear and consistent definition and a commonly agreed energy calculation methodology. The most important issues that should be given special attention before developing anewZEB definition are: (1) the metric of the balance, (2) the balancing period, (3) the type of energy use included in the balance, (4) the type of energy balance, (5) the accepted renewable energy supply options, (6) the connection to the energy infrastructure and (7) the requirements for the energy efficiency, the indoor climate and in case of gird connected ZEB for the building–grid interaction. This paper focuses on the review of the most of the existing ZEB definitions and the various approaches towards possible ZEB calculation methodologies. It presents and discusses possible answers to the abovementioned issues in order to facilitate the development of a consistent ZEB definition and a robust energy calculation methodology.

The present study assesses knowledge and knowledge acquisition regarding CSA in social work undergraduate students in a cross-sectional design. Three options for acquisition were assumed: 1) professional education, 2) media consumption, or 3) own experiences of CSA. Results indicated no improvement of knowledge through any of the prior mentioned sources and a high variability in knowledge. In contrast to expectations, personal experiences of CSA were associated with a higher threshold in recognition of CSA incidents. The meaning of the results for prevention and intervention are discussed by highlighting the role of taboos in professional education and the effects of media coverage.

In Germany, there is evidence that the prevalence of mental disorders also differs by occupation. The present study investigates whether for women working in male-dominated occupations and for men working in female-dominated occupations is related to depressive symptoms independently from other factors like work stress and work-family conflict. Special attention is paid to gender differences. Moreover, women are distinguished according to their working time (full-time or not). We use data from the first wave of the lidAstudy for our analyses. We make use of the applied Beck Depression Inventory, the effort-reward imbalance scales as well as the work-family conflict scale. Occupational gender segregation is defined as a share of 80 % of men and women per occupation, respectively. For women, the results of the multivariate analyses show an independent relationship between depressive symptoms and working in male-dominated occupations. Furthermore, significant interactions between occupational gender segregation and work stress are observed in both men and women regarding depressive symptoms.

T1 - Words Don't Come Easy to Me – Teaching Academic Writing to Engineering Students in the Age Of AI T2 - SEFI 53rd Annual Conference (SEFI 2025), Tampere, Finland, 15-18 September 2025 N2 - The competence of academic writing is currently still a central requirement for obtaining an academic degree. However, in teaching academic writing, lecturers have to deal with the two challenges of decreasing reading competence in young people and increasing use of artificial intelligence (AI) in reading and writing assignments. In engineering in particular, literacy understood as reading and writing competence is essential - whether for understanding complex tasks, analysing case studies or dealing with technical documents such as the product requirements document. Against this background, it is crucial to develop strategies and discuss modern approaches to specifically promote students' reading and writing skills and thus create an essential basis for successful scientific work and problem-solving. This workshop aims to stimulate an interactive exchange and develop practical solutions in the three core areas strengthening reading competence, developing academic writing skills, and substituting for reading and writing assessments.

Carsten Deckert shares his experience on the main innovation resistances and on ways to increase the acceptance of new ideas. He talks about which perceived attributes of innovations are conducive to the rate of adoption of an innovation and which are characteristics of failed innovations.

Objective: Quantitative data collection of relationships between the subjective well-being of heart transplant patients and selected influencing factors was investigated. Material and Methods: In a random sample of 97 heart transplant patients, quality of life was measured with the MLDL, subjective well-being with the HSWBS, social support with the SUCE-4, social activities, personality traits with the BFI-10 and the UGTS, as well as disease management according to the EFK, and physical complaints with the ERSD-SC TM were determined using an online survey. Results: In addition to physical well-being, social life, personality traits, the type of disease (chronic or spontaneous), and functional capacity have a significant impact on subjective well-being. Conclusion: In addition to physical well-being, psychosocial monitoring should also be established in transplantation medicine, and the long-term involvement of psychotherapists, psychiatrists, and social workers should be considered. After a heart transplantation, caring for the mind is just as essential as caring for the body, as subjective well-being is a product of the reciprocal influences of physical and psychological states.

Hence, the perception chain for autonomous driving is safeguarded against perturbations by imposing exaggerated optical quality requirements. Due to the non-linear coupling of optical elements, system requirements of camera-based Advanced Driver Assistance Systems (ADAS) can not be easily decomposed into individual part tolerances of the objective lens and the windscreen. This holds true for intensity-based part measurements, e.g. slanted edge measurements according to ISO12233, which can fundamentally not capture interference effects of the complex light field. Instead wavefront-based part measurements are required. Unfortunately, state-of-the-art wavefront measurement techniques are limited by the spanned sensitive area of the Shack-Hartmann lenslet array or the aperture stop of a corresponding interferometrical setup, respectively. Further, both measurements are limited by using collimated light only, whereas the target application has a large (angular) field of view, requiring many different measurements. We address those bottlenecks by proposing a novel wavefront aberration measurement procedure based on the Background Oriented Schlieren (BOS) method utilizing image auto-correlation. We analytically derive the governing equations for determining the Zernike coefficients of a wavefront aberration map in the knowledge of the local refractive power map obtained by a high-resolution BOS measurement. Furthermore, we experimentally demonstrate the feasibility of the measurement technique. Applying this novel method yields the promise of affordable wavefront aberration measurements only requiring a high-resolution camera and a sophisticated alignment strategy.

To increase the efficiency and economic viability of TEGs, research is performed on the materials on one hand and on the system connection on the other. In the latter case, the net output power of the cooling system plays a key role. At first glance, passive cooling seems preferable to active cooling because it does not affect the net electrical output power. However, as shown in the present review, the active cooling is to be preferred for net output power. The situation is similar in air and water-cooling. Even though air-cooling is easier to set up, the water-cooling should be preferred to achieve higher net output power. It is shown that microchannel cooling has similar hydraulic performance to conventional cooling and inserts increase the net output power of TEG. As the review reveals that active water-cooling should be the method of choice to achieve high net output power, it also shows that a careful optimization is necessary to exploit the potential.

In Germany, a growing number of young people with psychological disabilities in vocational rehabilitation can be observed. The study at hand focuses on this group and examines their (un-)unemployment biographies before vocational rehabilitation, their access to vocational rehabilitation and identifies their individual challenges within the process of vocational rehabilitation. Methods Using a multi-methods approach, we analyze representative administrative data of the German Federal Employment Agency as well as biographical interviews conducted with young rehabilitants. We compare the population of young rehabilitants with psychological disorders to those with other disabilities in terms of vocational rehabilitation and initial labor market entry in order to get a representative picture about their school to work transitions. Since rehabilitants with psychological disabilities tend to be older than the remaining population, analyses are stratified by age groups. In addition, qualitative in-depth interviews provide an additional and deeper understanding of specific employment barriers youth with psychological disorders have to overcome. Furthermore, the individual perspective gives insight on how the crucial transition from school to work is perceived by the population under study. Results The pathway into vocational rehabilitation of youth with psychological disorders is often characterized by obstacles in their transition from school to work. During rehabilitation, it appears essential to provide psychological stabilization along with vocational training. Although their average level of education is higher than those of other rehabilitants, labor market transition after (often company-external) vocational training challenges many young people with psychological disabilities, leaving many of them with comparatively poor labor market prospects. Conclusions Young persons with psychological disabilities, who come from regular schools or dropped out from regular school or university, seem to find their way to vocational rehabilitation more indirectly. Furthermore, vocational rehabilitation itself is often prolonged for those with psychological disabilities possibly due to a corresponding stabilization process. However, vocational rehabilitation can be a core element within the stabilization process of a psychological disease.

The Functionally Generated Path (FGP), produced as a surface which envelops the actual occlusal surface of the moving opponent jaw, can be used for compact representation of dynamic occlusal relations. In traditional dentistry FGP is recorded as a bite impression in a patient’s mouth. We propose an efficient computerized technique for FGP reconstruction and validate it through implementation and testing. The distance maps between occlusal surfaces of jaws, calculated for multiple projection directions and accumulated for mandibular motion, provide information for FGP computation. Rasterizing graphics hardware is used for fast calculation of the distance maps. Real-world data are used: the scanned shape of teeth and the measured motion of the lower jaw. We show applications of FGP to analysis of the occlusion relations and occlusal surface design for restorations.

The aim of the simulation is visual representation of characteristics relevant to the chewing process. The simulation is based on the construction of distance maps, which are visual representations of the distributions of the distances of points in a tooth to the opposite jaw. We use rasterizing graphics hardware for fast calculation of the distance maps. Distance maps are used for collision detection and for the derivation of various characteristics showing the distribution of load on the teeth and the chewing capability of the teeth. Such characteristics can be calculated for particular positions of the jaws; cumulative characteristics are used to describe the properties of jaw movement. This information may be used for interactive design of the occlusal surfaces of restorations and for jaw articulation diagnosis.

For realtime computer applications such as games, it is essential to represent shadows as accurate as possible. Also, various tv stations work with virtual studio systems instead of real studio sets. Especially for those systems, a realistic impression of the rendered and mixed scene is important. One challenge, hence, is the creation of a natural shadow impression. This paper presents the results of an empirical study to compare the performance and quality of different shadow mapping methods. For this test, a prototype studio renderer was developed. A percentage closer filter (pcf) with a number of specific resolutions is used to minimize the aliasing issue. More advanced algorithms which generate smooth shadows like the percentage closer soft shadow (pcss) method as well as the variance shadow maps (vsm) method are analysed. Different open source apis are used to develop the virtual studio renderer, giving the benefit of permanent enhancement. The Ogre 3D graphic engine is used to implement the rendering system, benefiting from various functions and plugins. The transmission of the tracking data is accomplished with the vrpn server/client and the Intersense api. The different shadow algorithms are compared in a virtual studio environment which also casts real shadows and thus gives a chance for a direct comparison throughout the empirical user study.

T1 - Viewpoint Diversity, Balance, Deliberativeness: Assessing the Media Performance of Migration Coverage Multi-Dimensionally Based on Deliberative Democratic Theories JF - Mass Communication and Society N2 - The issue of migration is highly salient in public debates in many countries. Given this salience and the risk of political instrumentalization, often by actors from the far right, it is important for citizens to receive high-quality, differentiated information on the migration issue. This touches upon the question of media performance. While there is abundant research on the media portrayal of the migration issue, this research strand is, surprisingly, hardly linked to research on media performance. We establish this link and present an innovative, sophisticated framework for standardized content analyses on migration. It combines three standards of media performance that are key to deliberative democratic theories—viewpoint diversity, balance, and deliberativeness—and utilizes value frames and the sociological concept of idea elements to measure viewpoint diversity and balance. A first empirical test of our newly developed approach, taking Germany as a case, shows noticeable differences in the media performance of 11 outlets analyzed. This test proves the applicability of our framework, which provides a valuable starting point for future comparative research on the media performance of migration coverage across countries and over time.

Our intention is to improve interaction with virtual objects in a virtual set, which are usually not directly visible to the actor, but only on distant displays. Vibrotactile feedback might improve the appearance on tv because an actor is able to look in any desired direction (camera or virtual object) or to read text on a teleprompter while interacting with a virtual object. Visual feedback in a virtual studio lacks spatial relation to the actor, which impedes the adjustment of the desired interaction. The five tactors of the implemented system which are mounted on the tracked arm give additional information like collision, navigation and activation. The user study for the developed system shows that the duration for reaching a certain target is much longer in case no visual feedback is given, but the accuracy is similar. In this study, subjects reported that an activation signal indicating the arrival at the target of a drag & drop task was helpful. In this paper, we discuss the problems we encountered while developing such a vibrotactile display. Keeping these pitfalls in mind could lead to better feedback systems for actors in virtual studio environments.

However, there is a lack of a general, robust and verifiable definition of what constitutes this behaviour. Therefore, this paper presents three simple scenarios that enable such a definition. They are based on simple black-box simulations that allow manufacturers to protect their development work. It can be shown that grid forming can be clearly distinguished from grid-following controls by their grid behaviour in the proposed scenarios. Extensive results illustrate this and also provide suggestions to deepen the understanding of grid-forming grid behaviour and its impact on system inertia. These findings should inspire the development of a clear definition and ultimately new requirements for converter systems.

Advanced virtual environments allow users to change realtime rendering features with a few manipulations, switching between different versions while still maintaining sensory immersion.

For this, detailed simulation models with a high temporal and technological resolution are required. When confronted with increasing weather-dependent renewable energy generation, probabilistic simulation models have proven. The significant computational costs of calculating a scenario, however, limit the complexity of further analysis. Advances in code optimization as well as the use of computing clusters still lead to runtimes of up to eight hours per scenario. However ongoing research highlights that tailor-made approximations are potentially the key factor in further reducing computing time. Consequently, current research aims to provide a method for the rapid prediction of widely varying scenarios. In this work artificial neural networks (ANN) are trained and compared to approximate the system behavior of the probabilistic simulation model. To do so, information needs to be sampled from the probabilistic simulation in an efficient way. Because only a limited space in the whole design space of the 16 independent variables is of interest, a classification is developed. Finally it required only around 35 minutes to create the regression models, including sampling the design space, simulating the training data and training the ANNs. The resulting ANNs are able to predict all scenarios within the validity range of the regression model with a coefficient of determination of over 0.9998 for independent test data (1.051.200 data points). They need only a few milliseconds to predict one scenario, enabling in-depth analysis in a brief period of time.

To quantify the influence we developed a probabilistic framework based on polynomial chaos (PC) that propagates stochastic input variables through any computational model. We considered a stochastic E-ρ relationship and a stochastic hip contact force, representing realistic variability of experimental data. Their influence on the prediction of principal strains (ϵ1 and ϵ3) was quantified for one human proximal femur, including sensitivity and reliability analysis. Large variabilities in the principal strain predictions were found in the cortical shell of the femoral neck, with coefficients of variation of ≈40%. Between 60 and 80% of the variance in ϵ1 and ϵ3 are attributable to the uncertainty in the E-ρ relationship, while ≈10% are caused by the load magnitude and 5-30% by the load direction. Principal strain directions were unaffected by material and loading uncertainties. The antero-superior and medial inferior sides of the neck exhibited the largest probabilities for tensile and compression failure, however all were very small (pf<0.001). In summary, uncertainty quantification with PC has been demonstrated to efficiently and accurately describe the influence of very different stochastic inputs, which increases the credibility and explanatory power of personalized analyses of human proximal femurs.

The new profile UMLsec4UML2 is technically constructed as a UML profile diagram, which is equipped with a number of integrity conditions expressed using OCL. Consequently, the UMLsec4UML2-profile can be loaded in any Eclipse-based EMF- and MDT-compatible UML editing tool to develop and analyze different kinds of security models. The OCL constraints replace the static checks of the tool support for the old UMLsec defined for UML 1.5. Thus, the UMLsec4UML2-profile not only provides the whole expresiveness of UML2.3 for security modeling, it also brings considerably more freedom in selecting a basic UML editing tool, and it integrates modeling and analyzing security models. Since UML2.3 comprises new diagram types, as well as new model elements and new semantics of diagram types already contained in UML1.5, we consider a number of these changes in detail. More specifically, we consider composite structure and sequence diagrams with respect to modeling security properties according to the original version of UMLsec. The goal is to use UMLsec4UML2 to specify architectural security patterns.

T1 - Translating community-wide spectral library into actionable chemical knowledge: a proof of concept with monoterpene indole alkaloids JF - Journal of Cheminformatics N2 - With over 3000 representatives, the monoterpene indole alkaloids (MIAs) class is among the most diverse families of plant natural products. The MS/MS spectral space exploration of these complex compounds using chemoinformatic and computational mass spectrometry tools offers a valuable opportunity to extract and share chemical insights from this emblematic family of natural products (NPs). In this work, we first present a substantially updated version of the MIADB, a database now containing 422 MS/MS spectra of MIAs that has been uploaded to the GNPS library versus 172 initial entries. We then introduce an innovative workflow that leverages hundreds of fragmentation spectra to support the FAIRification, extraction and dissemination of chemical knowledge. This workflow aims at the extraction of spectral patterns matching finely defined MIA skeletons. These extracted signatures can then be queried against complex biological extract datasets using MassQL. By applying this strategy to an LC-MS/MS dataset of 75 plant extracts, our results demonstrated the efficiency of this approach in identifying the diversity of MIA skeletons present in the analyzed samples. Additionally, our work enabled the digitization of structural data for diverse MIA skeletons by converting them into machine-readable formats and thereby enhancing their dissemination for the scientific community. Scientific contribution A comprehensive investigation of the monoterpene indole alkaloid chemical space, aiming to highlight skeleton-dependent fragmentation similarity trends and to generate valuable spectrometric signatures that could be used as queries.

The approach focuses on the practical relevant industrial setting where sharing and transferring gained knowledge among similar-behaved players improves the self-learning mechanism in large-scale systems. With TL-SbPGs, the gained knowledge can be reused by other players to optimize their policies, thereby improving the learning outcomes of the players and accelerating the learning process. To accomplish this goal, we develop transfer learning concepts and similarity criteria for players, which offer two distinct settings: (a) predefined similarities between players and (b) dynamically inferred similarities between players during training. We formally prove the applicability of the SbPG framework in transfer learning. Additionally, we introduce an efficient method to determine the optimal timing and weighting of the transfer learning procedure during the training phase. Through experiments on a laboratory-scale testbed, we demonstrate that TL-SbPGs significantly boost production efficiency while reducing power consumption of the production schedules while also outperforming native SbPGs.

For the investigations the measurement truck of the laboratory for environmental measurement techniques of the HSD was equipped with different measurement devices for gaseous and aerosol species as well as meteorological sensors. The measurement truck was placed next to a stationary air quality measurement container of the Environmental State Agency of North-Rhine-Westphalia (LANUV). The measurement site is located at the Cornelius street, a direct north south connecting street through the city of Duesseldorf, which is highly frequented by road traffic with an daily amount of about 45,000 vehicles. The street is located within the low emission zone (LEZ). Additionally the pass through of vehicles with a higher weight than 7.5 tons is prohibited. Within this study over a period of several weeks the particle mass concentrations PM10, PM2.5 and PM1, and the particle number size distribution (PNSD) were measured over a broad range from 5 nm to 32 µm with a high temporal resolution. Additionally, an aethalometer was used to determine the proportion of black carbon in the particle ensembles. Gaseous pollutants like nitrogen dioxide, ozone and sulphur dioxide were measured as well. Nitrogen dioxide is a typical species originating from combustion processes. In this study the data from NO2 strongly correlate with ultrafine particle and black carbon concentrations and for this reason all three species are clearly influenced by road traffic. However, this effect is not so pronounced for the particle mass concentrations, which are additionally influenced by the varying local background concentrations. During the measurements, the averaged concentration for PM10 was on a moderate level at 20.6 µg/m³ (PM2.5 13.4 µg/m³, PM1 10.7 µg/m³). The averaged NO2 concentration was 54.2 µg/m³ during the measurement period, which is above the yearly limit value of 40 µg/m³. However, the hourly limit value of 200 µg/m³ was not exceeded during the measurement period of this study. The averaged particle number concentration (PNC5-250 nm) and black carbon concentration were on a low level compared with values from other studies at roadsides. The PNC5-250 nm was at 6,400 #/cm³ and for black carbon at 1.8 µg/m³. The lower values for PNC and BC are possibly explained as a result due to the measures from the clean air plan. The measurements of this study took place in summertime. The air pollution concentrations might be higher during colder times of the year due to domestic fuel burning. After all it can be stated, that the additional monitoring of ultrafine particles and black carbon is relevant and important to characterize the composition of the air quality at roadsides and offer a better understanding for the temporal resolution of air pollutants in cities. Moreover, estimations on the risk of air pollution for the human health can more precisely be specified.

E-Learning Fachtagung Informatik der Gesellschaft für Informatik e.V., 10.-12. September 2018, Frankfurt am Main, Deutschland N2 - One of the main data sources for Learning Analytics are Learning Management Systems (LMS).These log files are limited though to interactions within the LMS and cannot take into account interactions of students in other applications and software in a digital learning environment. In this paper, we present an approach for generating log files based on mobile screen recordings as a data source for Learning Analytics. Logging mobile application usage is limited to rather general system events unless you have access to the source code of the operating system or applications.To address this we generate log files from mobile screen recordings by applying computer vision and machine learning methods to detect individually defined events. In closing, we discuss how these log files can be used as a data source for Learning Analytics and relevant ethical concerns.

Even though there are many benefits, the potential of immersive modelling has only been partly exploited due to unresolved problems such as ergonomic problems, numerous challenges with user interaction and the inability to perform exact, fast and progressive refinements. This paper explores past research, shows alternative approaches and proposes novel interaction tools for pending problems. An immersive modelling application for polygon meshes is created from scratch and tested by professional users of desktop modelling tools, such as Autodesk Maya, in order to assess the efficiency, comfort and speed of the proposed application with direct comparison to professional desktop modelling tools.

Differing perspectives, processes, methods, tools, vocabularies, and standards are problems that arise in this context. We present an approach to support bringing together disciplines based on a common body of knowledge (CBK), in which knowledge from different disciplines is collected, integrated, and structured. The novelty of our approach is twofold: first, it introduces a CBK ontology, which allows one to semantically enrich contents in order to be able to query the CBK in a more elaborate way afterwards. Second, it heavily relies on user participation in building up a CBK, making use of the Semantic MediaWiki as a platform to support collaborative writing. The CBK ontology is backed by a conceptual framework, consisting of concepts to structure the knowledge, to provide access options to it, and to build up a common terminology. To ensure a high quality of the provided contents and to sustain the community’s commitment, we further present organizational means as part of our approach. We demonstrate our work using the example of a Network of Excellence EU project, which aims at bringing together researchers and practitioners from services computing, security and software engineering.

Until now, spatial sound design has been based very much on experience and trial and error. Most effects are hand-crafted, because good design tools for spatial sound do not exist. This paper discusses spatial sound authoring and its applications, including shared virtual reality environments based on VRML. New utilities introduced by this research are an inspector for sound sources, an interactive resource manager, and a visual soundscape manipulator. The tools are part of a sound spatialization framework and allow a designer/author of multimedia content to monitor and debug sound events. Resource constraints like limited sound spatialization channels can also be simulated.

This article examines to what extent German tertiary education lives up to this expectation. The analysis of German module descriptions in engineering shows that there are no courses dedicated to creativity and that creativity and its techniques are mentioned only sparsely in the modules of the engineering curriculum. Surveys amongst our students show that they are usually familiar with techniques which are based on generating alternatives such as brainstorming and morphological box, but lack knowledge about techniques based on challenging assumptions such as forced connection. They tend to favour discursive techniques over intuitive ones and techniques which use generation of alternatives as an idea-generating principle. A combination of creativity techniques seems to be most conducive to creative output in our course. Finally, we present some first findings on creative sessions in remote work with the help of virtual whiteboards, which have gained in importance since the pandemic. Methodology – Firstly, we present an document analysis of the modules of Bachelor and Master programs of mechanical engineering at German universities and universities of applied sciences. Secondly, we present results from surveys in our Master course in “Innovation and Technology Management” where we gathered data from students over several years and performed an external evaluation of the output using Consensual Assessment Technique (CAT). These results include which creativity techniques the students know prior to the course and which they prefer as well as which techniques seem to be conducive to engineering creativity. Furthermore we surveyed their experiences with creative sessions as remote work. Conclusion – Overall, the article shows the importance to teach prospective engineers the basics in creativity. Students should have the opportunity to acquire knowledge about and apply different creativity techniques, as different techniques have different strengths and weaknesses and, thus, different areas of fruitful application. They should also have the chance to try out different modes such as in-person sessions and virtual sessions, as some of the future work will most likely shift online. Furthermore, a combination of different creativity techniques makes it more likely that engineers break through their usual systematic-analytic way of thinking and helps them to think outside the box to find creative solutions for the pressing problems of our time.

T1 - Tickling induces a unique type of spontaneous laughter JF - Biology Letters N2 - Laughing is ubiquitous in human life, yet what causes it and how it sounds is highly variable. Considering this diversity, we sought to test whether there are fundamentally different kinds of laughter. Here, we sampled spontaneous laughs (n = 887) from a wide range of everyday situations (e.g. comedic performances and playful pranks). Machine learning analyses showed that laughs produced during tickling are acoustically distinct from laughs triggered by other kinds of events (verbal jokes, watching something funny or witnessing someone else’s misfortune). In a listening experiment (n = 201), participants could accurately identify tickling-induced laughter, validating that such laughter is not only acoustically but also perceptually distinct. A second listening study (n = 210) combined with acoustic analyses indicates that tickling-induced laughter involves less vocal control than laughter produced in other contexts. Together, our results reveal a unique acoustic and perceptual profile of laughter induced by tickling, an evolutionarily ancient play behaviour, distinguishing it clearly from laughter caused by other triggers. This study showcases the power of machine learning in uncovering patterns within complex behavioural phenomena, providing a window into the evolutionary significance of ticking-induced laughter.
