In den Fokus wird die Perspektive von Schüler:innen genommen, die das Lernsetting über zehn Wochen erprobt haben. Ausgehend von qualitativen Leitfadeninterviews mit einer Teilstichprobe (n=12) beurteilen die Kinder die Rätselaufgaben, die Arbeit mit einem anderen Kind und die Arbeit mit einem digitalen Audiostift. Im Sinne der designbasierten Forschung werden aus den Beurteilungen der Kinder Gestaltungsprinzipien zur Weiterentwicklung des Lernsettings abgeleitet. Die Ergebnisse zeigen, dass die Perspektive der Schüler:innen in der designbasierten Forschung eine Bereicherung darstellen kann.}},

Unter Einbezug von Erkenntnissen aus der Verhaltensökonomie und der Mensch-Maschine-Interaktion wird analysiert, wie kognitive Limitationen, soziale Präferenzen und Wahrnehmungsverzerrungen das Verhalten in Kontexten von Unehrlichkeit, Empfehlungsumsetzung, Feedbackverarbeitung und Selbsteinschätzung prägen. Vier kontrollierte ökonomische Experimente zeigen, dass algorithmische Intransparenz unehrliches Verhalten verstärken kann, die Einbindung von Nutzern in das Training von KI-Systemen zwar deren Wahrnehmung verbessert, jedoch nicht die tatsächliche Befolgung algorithmischer Ratschläge fördert, dass Echtzeit-Feedback in Human-in-the-Loop-Systemen unbeabsichtigt Verhaltensverzerrungen verstärken kann und dass gängige Messungen von Selbstüberschätzung stark von methodischen Designentscheidungen abhängen. Die Dissertation unterstreicht die Notwendigkeit, realistische Annahmen über menschliches Verhalten bei der Gestaltung von Prüfungsprozessen, Empfehlungssystemen und interaktiven Technologien zu berücksichtigen und leistet damit einen Beitrag zu einem besseren Verständnis menschlicher Entscheidungsprozesse in einer zunehmend automatisierten Welt.}},

abstract = {{This paper deals with the implementation and results of the application of a multi-stage traffic light control system which includes a simulation-based traffic estimation and model predictive control.
The traffic light control system incorporates a fuzzy system for traffic light phase preselection, followed by a model predictive control to optimise phase combinations and switching times. Predefined phases are selected without restrictions in the order according to a multi-objective optimisation to adapt to the traffic as freely as possible. Initially, the system is tested in simulations and compared with existing methods and analysed afterwards for its effectiveness in a prototype commissioning in field tests. Results indicate high potentials for reducing emissions and waiting times, highlighting the system's value. However, further refinement is necessary for standard implementation. This comprehensive approach demonstrates advancements in traffic management technology, showcasing the potential for enhancing urban mobility and reducing environmental impact.}},

abstract = {{It is a widely accepted standard practice to implement cryptographic software so that secret inputs do not influence the cycle count. Software following this paradigm is often referred to as “constant-time” software and typically involves following three rules: 1) never branch on a secret-dependent condition, 2) never access memory at a secret-dependent location, and 3) avoid variable-time arithmetic operations on secret data. The third rule requires knowledge about such variable-time arithmetic instructions, or vice versa, which operations are safe to use on secret inputs. For a long time, this knowledge was based on either documentation or microbenchmarks, but critically, there were never any guarantees for future microarchitectures. This changed with the introduction of the data-operand-independent-timing (DOIT) mode on Intel CPUs and, to some extent, the data-independent-timing (DIT) mode on Arm CPUs. Both Intel and Arm document a subset of their respective instruction sets that are intended to leak no information about their inputs through timing, even on future microarchitectures if the CPU is set to run in a dedicated DOIT (or DIT) mode.In this paper, we present a principled solution that leverages DOIT to enable cryptographic software that is future-proof constant-time, in the sense that it ensures that only instructions from the DOIT subset are used to operate on secret data, even during speculative execution after a mispredicted branch or function return location. For this solution, we build on top of existing security type systems in the Jasmin framework for high-assurance cryptography.We then use our solution to evaluate the extent to which existing cryptographic software built to be “constant-time” is already secure in this stricter paradigm implied by DOIT and what the performance impact is to move from constant-time to future-proof constant-time.}},
