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.
