Computational Thinking (CT) has become a central theme in K–12 Computer Science education. Over the past twenty years, multiple conceptualizations of CT have emerged, many forming the basis for assessment instruments. One such conceptualization was developed for the large-scale International Computer and Information Literacy Study (ICILS), which assessed CT across 24 countries using representative sampling. The size and sampling quality of the ICILS data set allow for robust statistical analyses which in turn will be of interest to researchers and policy-makers alike. This study situates the ICILS 2023 conceptualization of CT within other established frameworks and conducts a secondary analysis of the ICILS 2023 CT data on non-cognitive antecedents and processes. Methods . Structured deductive content analyses compare the ICILS 2023 items with those from the Bebras Challenge on Informatics and Computational Thinking [13] ( Bebras ) and the Computational Thinking Test [55]) ( CTt ), mapped across three CT frameworks—ICILS [28], Shute et al. [65] and Weintrop et al. [71]—and aligned with Bloom's revised taxonomy [2]. Linear regression analyses on the data of the 20 educational contexts that provided not only CT performance data but also a complete coverage of student data relative to the predictors of CT performance studied in prior work examine the predictive effect of non-cognitive factors on CT performance. Results . The qualitative analyses showed that the ICILS 2023 CT items can be mapped to existing frameworks. Conversely, items from both Bebras and CTt can be mapped to the ICILS framework. The distinct, partially overlapping profiles of the instruments across the frameworks as well as Bloom's taxonomy indicate that they are complementary in assessing CT, confirming and expanding prior comparisons of Bebras and CTt . The regression analyses indicate no single dominant predictor of CT performance. The association of socio-economic status, gender, or the home language was consistent with prior findings, predictors related to learning processes, however, vary across educational contexts. Discussion . Our results demonstrate that ICILS 2023 items can be mapped onto multiple established CT frameworks, supporting their broader validity and utility for comparative research. The findings of the regression analysis underscore the complex interplay of non-cognitive factors affecting CT and illustrate the significance of contextual interpretation within educational systems. }}, author = {{Vahrenhold, Jan and Niemann, Jan and Drossel, Kerstin}}, issn = {{1946-6226}}, journal = {{ACM Transactions on Computing Education}}, publisher = {{Association for Computing Machinery (ACM)}}, title = {{{Computational Thinking in ICILS 2023: Analyzing the Construct and Its Antecedent- and Process-Level Predictors}}}, doi = {{10.1145/3813115}}, year = {{2026}}, } @article{65554, abstract = {{Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction, while supporting not only contractible but also incontractible loops on the boundaries of manifold objects of higher genus and arbitrary non‐trivial topology. We describe an implementation of this algorithm in the discrete setting, with triangle mesh cut surfaces embedded in tetrahedral mesh objects. Making use of this novel cutting algorithm, we describe a method for the reliable construction of bijective volumetric maps between solid objects, demonstrating the algorithm's utility. This mapping method overcomes restrictions of the state of the art to topological balls, extending coverage to objects of arbitrary genus, specifically so‐called 1 ‐handlebodies. }}, author = {{Hinderink, Steffen and Campen, Marcel}}, issn = {{0167-7055}}, journal = {{Computer Graphics Forum}}, publisher = {{Wiley}}, title = {{{DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping}}}, doi = {{10.1111/cgf.70379}}, year = {{2026}}, } @article{65553, author = {{Golebiowska, Sandra Alicja and Meinderink, Dennis and Ebbert, Christoph and Kollmann, Sabrina and Neßlinger, Vanessa and Grundmeier, Guido}}, issn = {{0143-7496}}, journal = {{International Journal of Adhesion and Adhesives}}, publisher = {{Elsevier BV}}, title = {{{Two-electrode electrochemical impedance spectroscopy at polymer/oxide interfaces}}}, doi = {{10.1016/j.ijadhadh.2026.104360}}, volume = {{149}}, year = {{2026}}, } @inbook{65550, abstract = {{

We develop an appropriate notion of contrastive explanations for the special case of ABox reasoning with description logic ontologies, and analyze the computational complexity for different variants under different optimality criteria, considering lightweight as well as more expressive description logics.

In this paper, by exploiting connections with diverse areas including the theory of algebraic curves, cyclotomy and the enumeration of irreducible polynomials, we establish new results and resolve various Open Problems of Li and Pott. We prove geometric results which shed new light on the relationship between intersection distribution and projective equivalence of polynomials, and algebraic results which describe and characterise the degree of Sf - the index of the largest non-zero entry in the intersection distribution of f.

To reduce the time and cost associated with extensive experimental investigations, numerical modeling strategies are increasingly applied. In this numerical study, a further step in the modelling strategy for the direct pin-pressing (DPP) process of cFRTP and metal sheets is presented. The study focuses on modeling and simulating the occurring deformation mechanisms of decomposition, compaction, and separation of individual rovings on the mesoscale to analyze the resulting material structure. For this purpose, two simplified models were derived. The textile architecture is represented based on micrographs of cross-sections and discretized using the finite element method. The deformation of individual rovings during joining leads to a deformation of their initial elliptical cross section. To capture this level of resolution, both a cohesive zone and a pure contact approach are applied within the rovings. The highly viscous thermoplastic melt is modeled as a fluid employing the Arbitrary Lagrange–Eulerian (ALE) method. Matrix and roving meshes are coupled to account for fluid–structure interaction (FSI) during process. The study shows that coupling of matrix and rovings is necessary to obtain more accurate predictions of the deformation behaviour. Furthermore, the cohesive zone approach is better suited to simulate the emerging deformation mechanisms.}}, author = {{Gröger, Benjamin and Gerritzen, Johannes and Hornig, Andreas and Gude, Maik}}, issn = {{1662-9795}}, journal = {{Key Engineering Materials}}, pages = {{227--234}}, publisher = {{Trans Tech Publications, Ltd.}}, title = {{{Modelling Deformation Mechanisms Decomposition, Separation and Compaction in Mechanical Joining Processes of Fiber Reinforced Thermoplastics on Meso Scale}}}, doi = {{10.4028/p-e8wywr}}, volume = {{1050}}, year = {{2026}}, }
