Racism is a structural component of our society, and as Broden and Mecheril state, “racism educates.” As ‘guardians of cultural meaning’, textbooks have an integral part in this education. Starting from these assumptions, we identify and map out implications for anti-racist textbook analysis as a field of research-based teacher education in the foreign languages, hoping to stimulate racism-critical work on textbooks in teacher education. We will give an overview of anti-racist textbook analyses in foreign language education, educational sciences and other pedagogical fields, showing theoretical frameworks and research methodologies employed. Against this backdrop, we present approaches to anti-racist textbook analysis as well as specific methodologies. With Critical Discourse Analysis as our umbrella concept, we develop guiding principles for anti-racist textbook analysis, which we regard as a cornerstone of critical foreign language teacher education. We will illustrate these principles and methodologies with examples from a Spanish and an English textbook.
Digital competence is essential for students and professionals in health and nursing education. Based on the DigComp 2.2 framework, this study examines the self-assessed digital competencies of students from Germany, Ukraine, and Kazakhstan across five core dimensions, aiming to identify national differences and potential misalignments between perceived and reported digital competences.
Methods: A cross-sectional online survey (n = 269) was conducted among students in health-related fields. Participants rated their digital competence on 15 items aligned with DigKomp 2.2 questionnaire. Quantitative data were analyzed descriptively and with ANOVA (two-tailed, p < 0.05), using Games–Howell post-hoc tests in case of heterogeneity of variances and Kruskal–Wallis/Mann–Whitney tests as sensitivity analyses. In addition, an open-ended knowledge question asked respondents to describe their strategies for finding reliable online information. Responses were analyzed descriptively and qualitatively using inductive coding.
Results: While all groups reported generally high digital competence, German students rated themselves significantly lower in the Digital content creation dimension compared to their peers and the KaWuM reference sample. However, their responses to the open-ended question revealed methodologically advanced search strategies, including systematic literature reviews (n = 8), Boolean operators (n = 6), and use of AI tools (n = 1). Ukrainian students emphasized heuristic and comparative approaches, while Kazakhstani responses reflected pragmatic strategies under infrastructural constraints.
Discussion: The findings suggest a mismatch between self-assessed and actual digital competence, particularly among German students, who may underestimate their skills. This highlights the importance of triangulating quantitative self-reports with qualitative diagnostics. The study underscores the need for embedded digital skills training, especially in Digital content creation, across national contexts in health education.
Conductance quantization in memristive devices with electrodeposited Prussian blue-based dielectrics

Understanding the fracture mechanisms in brazed joints offers opportunities to improve joint design and brazing processes. Traditional ex-situ methods cannot capture the material behavior in real-time, making in-situ observation during mechanical testing, such as in SEM, invaluable. In the present work, in-situ bending tests were used to observe the crack propagation in brazed joints exhibiting both ductile and brittle fracture mechanisms. Samples were prepared with precise geometries and notched to initiate cracks in the joining zone. These in-situ tests provide valuable data on the mechanical behavior of brazed joints, offering insights into their failure processes. Three different joints were analyzed: AISI 304 brazed with AgCu filler metal, Mar M 509 brazed with Co-based filler metal and mixed joints of AA 6082 and AISI 304 brazed with AlGeSi filler metal. In the medium strength joint brazed with Ag 272 filler metal, the fracture occurred by slipping through the eutectic. In the high strength joint brazed with Co 900 filler metal, the crack propagated transgranularly through the intermetallic phases and stopped at the interface between the intermetallic and Co solid solution. The AA 6082 / AISI 304 joint was studied using an overlap geometry, showing that microcracks formed as the bending stress increased, finally leading to a failure at the Al7Fe2Si intermetallic layer, a critical microstructural feature. The used test procedure is suitable for further observations on the fracture mechanism in joints brazed in specific geometries as well as using different brazing process parameters and comparing the results with existing investigations.

Development of an Interface for the Synchronization of Delivery Dates in an ERP Migration Phase
(2025)
This paper focuses on designing a robust interface solution for synchronizing critical delivery dates during a complex ERP migration phase, necessitated by the parallel operation of a legacy system and a new target system. The core challenge is that automatic rollback operations triggered between the synchronized ERP systems—due to technical errors—are systematically not communicated to the downstream PPC systems (Production Planning and Control systems). This data inconsistency leads to significant business risks, including production disruptions, delivery delays, and increased inventory costs. The developed solution implements an API-centric approach based on Microservices principles to ensure loose coupling between the systems. It utilizes a two-stage synchronization mechanism to proactively resolve these inconsistencies. First, a time-delayed individual validation employs a strategic 30-minute buffer time to guarantee that potential ERP rollback operations are completed before consistency checks with the PPC system begin. Second, a comprehensive nightly consistency validation systematically reviews all business-relevant delivery dates within a defined time window and initiates automatic corrections. The system's status-based processing model, combined with comprehensive logging and a "Live-Feed" Web Interface, guarantees transaction security and complete traceability. This approach successfully minimizes business risks during the critical transition and offers an effective design pattern for handling rollback situations in similar complex, heterogeneous integration projects.
