Even at young ages, children self-report experiencing math anxiety, which negatively relates to their math achievement. Leveraging a large dataset of first and second grade students' math achievement scores, math problem solving strategies, and math attitudes, we explored the possibility that children's math anxiety (i.e., a fear or apprehension about math) negatively relates to their use of mo...

Although the detrimental effects of math anxiety in adults are well understood, few studies have examined how it affects younger children who are beginning to learn math in a formal academic setting. Here, we examine the relationship between math anxiety and math achievement in second and third graders. In response to the need for a grade-appropriate measure of assessing math anxiety in this gr...

Computerunterstützte Systeme sind heute aus dem medizinischen Alltag nicht mehr wegzudenken, auch wenn ihr Nutzen in aller Regel nicht in prospektiv-randomisierten Untersuchungen beschrieben wurde. Während in der industriellen Arbeitswelt computerunterstützte robotische Systeme auf Grund ihrer Präzision und Ausdauer uneingeschränkt akzeptiert werden, gibt es im medizinischen Bereich heftige Dis...

This contribution tries to highlight the importance of Minkowski’s “Raum und Zeit” lecture in a “negative” way, where negative is taken in the photographic sense of reversing lights and shades. Indeed, we focus on the “shades” of Minkowski’s text, i.e. what is missing, or misunderstood. In particular, we focus on two issues: (i) why are Poincaré’s pioneering contributions to four-dimensional ge...

For several real-world problems, signal processing approaches are most successful when they combine the insight offered by the physics underlying the problem with the mathematical framework and tools inherent in digital signal processing. Imaging systems are a particularly fertile ground for problems in this class because they deal specifically with the capture of physical scenes and with the r...

The notion of ciphertext undetectability was introduced in [Gaži, P. – Stanek, M.: On ciphertext undetectability, Tatra Mt. Math. Publ. 41 (2008), 133–151] as a steganographic property of an encryption scheme. While finding the relationship between ciphertext undetectability and indistinguishability of encryptions, authors showed that ciphertext undetectability does not imply indistinguishabili...
