Circularity of wood products can reduce this demand by improving resource efficiency, but barriers like uncertain availability and quality of post-consumer wood hinder implementation. This study optimizes and extends the PRecTimber model to forecast post-consumer wood quantities and qualities in Germany (revised with quality information), Finland, and Sweden. By 2050, predicted post-consumer wood volumes are 14.11 Mt in Germany, 1.64 Mt in Finland, and 2.74 Mt in Sweden, mainly from the construction sector. Our quality assessment methodology with scenario analysis (status quo S0 and improved scenarios S1-S2 with +10 and +20 percentage-point gains in key quality factors) reveals that the shares of post-consumer construction sawnwood suitable for lifespan extension and material recycling, respectively, are 25 \% and 59 \% under S0, 36 \% and 50 \% under S1, and 49 \% and 38 \% under S2. Leveraging these quantity and quality insights, policy reforms can support industries and technological innovation to optimize the use of post-consumer wood.}, language = {en} } @article{Kastl2025, author = {Kastl, Andrea}, title = {Empathy mapping and hybrid persona creation: Understanding older adults' needs in technology design for ageing in place}, series = {Computational and structural biotechnology journal}, volume = {28}, journal = {Computational and structural biotechnology journal}, publisher = {Elsevier}, doi = {10.1016/j.csbj.2025.11.044}, pages = {552 -- 563}, year = {2025}, abstract = {Background: Technology yields the potential to support independence in later life and facilitate ageing in place. Barriers such as limited usability, varying levels of digital literacy, and persistent age-related stereotypes are documented to hinder technology adoption among older adults. User-centered design approaches, such as the persona method, offer strategies to address these challenges. Objective: Personas were created to inform the development of technologies supporting ageing in place by enhancing stakeholders' understanding of needs and technology experience among older adults. Methods: The personas were developed through an iterative process, with this paper detailing the last stage, which employed the a PATHY technique as conceptual framework for content analysis. Eleven focus group discussions were conducted in southern Germany, of which nine were included in the analysis. These involved older adults in need of support, with orthopedic and neurological conditions, and in informal caregiving roles. Results: Five hybrid personas were created to represent the target groups' experiences related to ageing in place, each reflecting needs, problems, existing solutions, habits, sociodemographic characteristics, and dimensions of technology experience. Key factors influencing technology experience and uptake among the personas were identified, including the social context and availability of support, the perceived trade-off between safety and digital privacy, and the persistence of the digital divide. Conclusion: The findings underscore the necessity of adaptable, context-sensitive technology solutions, displayed by the personas' needs, pains, routines and technology experiences. Thereby, the hybrid personas reinforce the importance of a more relational and context-aware approach in user-centered design.}, language = {en} } @article{BrandtHeidl2025, author = {Brandt, Hanna and Heidl, Christian}, title = {Happiness and a sense of effectiveness through self-determination, physical and mental health}, series = {Health Psychology: Applications in Clinical and Sports Contexts}, journal = {Health Psychology: Applications in Clinical and Sports Contexts}, publisher = {Nomos}, address = {Baden-Baden}, doi = {10.5771/9783748954804-9}, pages = {9 -- 20}, year = {2025}, language = {en} } @article{MayrRoessle2025, author = {Mayr, Ilona and R{\"o}ßle, Felix}, title = {Financial Performance of Mid-and High-Tech Industries in Crisis and Non-Crisis Periods}, series = {Current Issues of Business and Law}, volume = {2025}, journal = {Current Issues of Business and Law}, number = {2(9)}, pages = {14 -- 26}, year = {2025}, abstract = {Investments in research and development (R\&D) are crucial for innovation and economic growth, yet dis-tinctions between high-tech and mid-tech industries may lead tovarying financial outcomes.

Certification of cloud services is the most promising method in overcoming the current issues. However, this paper examines that existing certificates for cloud service providers don't match the requirements of public administrations. The analyzed cloud certificates focus strongly on the information security management. But they only have a general look on data protection management. The missing focus on the special requirements of public administrations with regards to geo location of servers, the US cloud act, and especially prevention of foreign state access of PII data (personally identifiable information) is most critical for the use in public administrations. This article shows that a FedRAMP equivalent certification process combined with a European cloud certificate especially designed for the public administration could be the trigger to a successful and faster cloud implementation in the public administration sector in Europe that is currently underdeveloped. Furthermore, the large market with millions of buying public administrations in 27 European Union countries would create attractive business opportunities for private cloud providers, foster the development of new applications and serve the strategic goal of data sovereignty.}, language = {en} } @article{SchwarzKnieleLindner2025, author = {Schwarz, Benedikt and Kniele, H. and Lindner, Johannes}, title = {Automated Process Optimization in a Novel TripleShaft Mixer with Adaptive Mixing Modes}, series = {Chemie Ingenieur Technik}, journal = {Chemie Ingenieur Technik}, publisher = {Wiley-VCH}, address = {Weinheim}, doi = {10.1002/cite.70060}, year = {2025}, abstract = {A novel multi-purpose mixer was set up, which allows the change of the blade angle during the process and provides aflow field with respect to the needs of the mixing task.

This allows control over the flow velocity within the cyclone, thereby maintaining a constant tangential velocity despite changes in volumetric flow rate. The prototype demonstrated a constant separation efficiency across a volumetric flow range spanning a factor of two between its minimum and maximum capacities. Two control strategies were investigated: operation at constant pressure drop and operation at constant inlet velocity, both under varying flow rates and inlet geometries. To initially examine the influence of key parameters, hydrocyclones with fixed geometries were fabricated using rapid prototyping and employed in experimental trials.

However, technical and organizational barriers exist, which limit the widespread adoption of BIM. This study therefore employed two large-scale, online surveys to analyze the technical and organizational aspects of BIM implementation in lighting design. The results show that, in addition to technical barriers, successful BIM implementation hinges on knowledge, acceptance, and organizational learning ability. Training, internal processes and a supportive corporate culture are crucial for the effective use of new workflows. Fragmented planning processes and asynchronous participation reinforce technical limitations. To fully realize the potential of BIM, an integrated approach combining technological innovations with organizational learning and collaborative structures is essential.

They can be an effective tool for delivering educational content, providing flexibility in time and location and improving students' understanding of the material. The effectiveness of such videos may be enhanced by applying principles for multimedia design, which are based on a cognitive theory of multimedia learning. One way to adhere to those principles is by showing the instructor together with additional visuals on screen. Some studies suggest that this may have a positive effect on student learning and overall performance. The combination of the instructor and other visuals is usually done in post-production editing, which can be a time-consuming process. In this paper, a live composition video format is proposed, where the instructor is integrated into the presentation during recording. Using this approach, it is possible for the instructor to interact with added visuals directly, requiring little to no post-production. Furthermore, this method can also be used to enrich and increase the efficacy of synchronous live online lectures.}, language = {en} }
