This study examines the role of\r\nproblem-solving heuristics among 73 sixth-grade students in a German secondary\r\nschool (Gesamtschule). Specifically, we focus on the empirical relationship between\r\nthe occurrence of heuristics, their suitability, and application, as well as their contribution\r\nto problem-solving success. To this end, we developed a heuristic training that\r\nintroduced strategy keys (heuristic aid cards) accompanied by explanatory videos. By\r\nleveraging variations in the successful application of the heuristics between students\r\nand across multiple sessions (73 students in 4 training situations and 3 problems\r\nin a final test), we discover from regression models with student and task-fixed effects\r\nthat a successful use of heuristics (i.e., an heuristic occurred, that heuristic had\r\na high suitability regarding the problem, and it was applied correctly) leads to more\r\nsuccessful mathematical problem solving. Regarding the underlying mechanism, we\r\nfind that all dimensions of heuristic use (occurrence, suitability, and application\r\nof heuristics) are positively related to problem-solving success. When comparing\r\nthe predictive capacity of all three aspects, we identified the correct application of\r\nheuristics as particularly conducive for better problem-solving success. In comparing\r\nthe group of students with high to those with low initial math competence, we find no significant differences in the relationship between heuristic use and problemsolving\r\nsuccess across achievement groups. Our results emphasize the crucial role\r\nof heuristic application in mathematical problem solving, which generally benefits\r\nstudents regardless of their overall math competence."}],"issue":"6","publication":"Journal für Mathematik-Didaktik","user_id":"126182","ddc":["510"],"volume":47,"_id":"65865","has_accepted_license":"1","status":"public","oa":"1","quality_controlled":"1","file_date_updated":"2026-06-15T10:03:48Z","citation":{"ama":"Herold-Blasius R, Kleinschmidt H, Ziller C.

However, the necessary adaptation of the rivet-die combination to the respective material and thickness combinations requires a large number of specific tool sets, which significantly limits the process's flexibility. To overcome these limitations, the versatile self-piercing riveting (V-SPR) was developed, which features enhanced punch actuation in combination with a multi-range-capable rivet . In this context, the concept of a movable die was introduced, which enables an extended process window and adaptable joint formation. Kappe et al. presented initial studies demonstrating the potential of this approach . However, a detailed numerical understanding of the underlying mechanisms remains lacking. This paper presents a numerical analysis of V-SPR with a movable die using a finite element (FE) model. The model includes deformable rivets, sheet metal materials and a kinematically controlled die with adjustable movement. A parameter study was conducted to analyse the influence of die movement on the material flow of the rivet and sheets, as well as joint formation. The simulations were validated using selected experimental data. The goal is to compare the joint geometries achieved with fixed and moving dies and expand the process windows of VSPR. The results demonstrate that the movable-die concept significantly enhances the material flow of both the sheets and the rivet, resulting in a noticeably larger and more reliable interlock than what is achievable with V-SPR using a fixed die. The numerical analyses support the observations reported by Kappe et al. and extend them by providing a quantitative description of how die displacement influences the resulting interlock size. Moreover, the ability to precisely control the die movement makes it possible to join challenging sheet-metal combinations that are difficult to process with conventional setups, particularly in cases involving thicker sheet materials."}],"publication":"Materials Science Forum"},{"date_updated":"2026-06-16T07:09:53Z","author":[{"full_name":"Stojko, Laura","first_name":"Laura","last_name":"Stojko"},{"last_name":"Herder","first_name":"Eelco","full_name":"Herder, Eelco"},{"first_name":"Jannis","last_name":"Strecker-Bischoff","full_name":"Strecker-Bischoff, Jannis"},{"first_name":"Julia Seitz","last_name":"Sänger","full_name":"Sänger, Julia Seitz"},{"last_name":"Neumayr","first_name":"Thomas","full_name":"Neumayr, Thomas"},{"full_name":"Yigitbas, Enes","last_name":"Yigitbas","first_name":"Enes"},{"full_name":"Augstein, Mirjam","first_name":"Mirjam","last_name":"Augstein"}],"title":"ABIS 2026: The Effects of the Adaptive Web on Society","status":"public","year":"2026","editor":[{"last_name":"Balke","first_name":"Wolf-Tilo","full_name":"Balke, Wolf-Tilo"},{"last_name":"Plötzky","first_name":"Florian","full_name":"Plötzky, Florian"},{"last_name":"Spaniol","first_name":"Marc","full_name":"Spaniol, Marc"},{"full_name":"Herder, Eelco","first_name":"Eelco","last_name":"Herder"},{"first_name":"Lydia","last_name":"Manikonda","full_name":"Manikonda, Lydia"},{"last_name":"Liu","first_name":"Haiming","full_name":"Liu, Haiming"},{"last_name":"Ibáñez","first_name":"Luis-Daniel","full_name":"Ibáñez, Luis-Daniel"},{"full_name":"Rezapour, Rezvaneh","first_name":"Rezvaneh","last_name":"Rezapour"}],"user_id":"8447","doi":"10.1145/3795513.3810983","language":[{"iso":"eng"}],"_id":"65902","publisher":"ACM","page":"108–109","citation":{"apa":"Stojko, L., Herder, E., Strecker-Bischoff, J., Sänger, J.

While recent applications of qualitative comparative analysis (QCA) have begun to model such configurational links, their hierarchical nature has received little empirical attention. As this paper demonstrates, theories that posit hierarchical configurations can and should be explored using the two‐step variant of QCA. The paper outlines the potential of the method for the field of creativity and innovation and helps to navigate key modelling decisions. An illustrative study explores the occurrence of informal employee innovation behaviour—workarounds—based on the Ability‐Motivation‐Opportunity (AMO) framework. The results of the two‐step QCA are superior in terms of reduced limited diversity and complexity to those of the conventional one‐step QCA. Overall, the method has considerable potential for empirically capturing the complex, hierarchical interactions inherent in many innovation processes.</jats:p>"}],"citation":{"short":"L.

How-ever, the reliable and cost-efficient joining of aluminium components remains a challenge. Mechanical joining methods, such as riveting, are frequently used in the automotive and aerospace construction industries. Rivets are made from heat-treated steels. Compared to steel, the use of aluminium materials for fasten-ers offers several advantages in terms of joining properties, particularly in terms of recyclability, corrosion resistance and reduced weight of the joined structure. Additionally, the manufacturing process is shorter since aluminium fasteners do not require coating. However, aluminium rivets can often not be used due to the insufficient mechanical strength of the fastener material in relation to the joining component materials.\r\nThis study systematically investigates the requirements for using solid alu-minium self-piercing rivets. The influence of rivet geometry adjustments on the joint quality is analysed using numerical simulation. The results are used to derive and evaluate an optimised rivet geometry for joining pure aluminium sheets. On this basis, solid self-drilling rivets with optimised geometry are manufactured from particle-reinforced aluminium produced in a continuous extrusion process by machining. The integration of particles increases the material’s strength. Exper-imental tests are conducted to evaluate the use of optimised solid self-piercing rivets. The quality-relevant parameters are determined and evaluated based on macrographs of the joints.","lang":"eng"}],"date_created":"2026-05-26T12:16:57Z","department":[{"_id":"43"},{"_id":"157"}],"type":"book_chapter","keyword":["Solid self-piercing riveting cdot particle-reinforced aluminium cdot continuous powder extrusion cdot Joining technology cdot Rivet geometry cdot lightweight design"],"publication_identifier":{"isbn":["9783032236401","9783032236418"],"issn":["2731-0221","2731-023X"]},"author":[{"last_name":"Koch","first_name":"Steffen","full_name":"Koch, Steffen"},{"first_name":"Joshua","last_name":"Weber","full_name":"Weber, Joshua"},{"first_name":"Gerson","last_name":"Meschut","full_name":"Meschut, Gerson"},{"full_name":"Stadelmann, Claudia","last_name":"Stadelmann","first_name":"Claudia"},{"last_name":"Böhm","first_name":"Wolfgang","full_name":"Böhm, Wolfgang"},{"first_name":"Marion","last_name":"Merklein","full_name":"Merklein, Marion"}],"year":"2026","title":"Particle-Reinforced Aluminium Solid Self-piercing Rivets for Joining Aluminium Alloy Sheets","date_updated":"2026-06-16T13:21:39Z","publication_status":"published","language":[{"iso":"eng"}],"doi":"10.1007/978-3-032-23641-8_1"},{"author":[{"id":"3959","last_name":"Jesinghausen","orcid":"https://orcid.org/0000-0003-2611-5298","first_name":"Steffen","full_name":"Jesinghausen, Steffen"},{"id":"464","last_name":"Schmid","orcid":"000-0001-8590-1921","first_name":"Hans-Joachim","full_name":"Schmid, Hans-Joachim"}],"status":"public","year":"2026","title":"Adaptive Coaxial Concrete Rheometer (ACCR): Honest Rheological Measurements and Corrections","date_updated":"2026-06-17T04:46:05Z","language":[{"iso":"eng"}],"_id":"65915","main_file_link":[{"open_access":"1","url":"https://link.springer.com/book/10.1007/978-3-032-15391-3"}],"doi":"10.1007/978-3-032-15391-3","user_id":"3959","citation":{"chicago":"Jesinghausen, Steffen, and Hans-Joachim Schmid. “Adaptive Coaxial Concrete Rheometer (ACCR): Honest Rheological Measurements and Corrections.” In <i>Opus Fluidum Futurum—Rheology of Reactive, Multiscale, Multiphase Construction Materials</i>, 2026. <a href=\"https://doi.org/10.1007/978-3-032-15391-3\">https://doi.org/10.1007/978-3-032-15391-3</a>.","short":"S.
