Zusammenfassung. Dieser Beitrag fasst ausgewählte Ergebnisse der Dissertation „Beobachtungsmöglichkeiten im Domain Name System: Angriffe auf die Privatsphäre und Techniken zum Selbstdatenschutz“ [7] zusammen. Die Dissertation liefert neue Antworten auf die Fragen „Wer kann uns im Internet überwachen?“ und „Wie schützen wir uns davor?“. Die Arbeit befasst sich mit dem Domain Name System (DNS), d...

This experiment examined the eVects of implicit gender-math stereotyping and implicit gender and math identiWcation on women’s math performance under stereotype threat and reduced threat conditions. Results showed that of the three, only implicit gender-math stereotyping moderated stereotype threat eVects on women’s math performance: women who showed less implicit math-gender stereotyping showe...

Underperformance in math is a problem with increasing prevalence, complex etiology, and severe repercussions. This study examined the etiological heterogeneity of math performance in a sample of 264 pairs of 12-year-old twins assessed on measures of math achievement, numerosity and math anxiety. Latent profile analysis indicated five groupings of individuals representing different patterns of m...

Girls tend to have more negative math attitudes, including gender stereotypes, anxieties, and self-concepts, than boys. These attitudes play a critical role in math performance, math course-taking, and the pursuit of mathrelated career paths. We review existing research, primarily from U.S. samples, showing that parents’ and teachers’ expectancies for children’s math competence are often gender...

BACKGROUND The present study investigated the role of early language abilities in the development of math skills among Chinese K-3 students. About 2000 children in China, who were on average aged 6 years, were assessed for both informal math (e.g., basic number concepts such as counting objects) and formal math (calculations including addition and subtraction) skills, language abilities and non...

Here we investigate the canonical Gaussian map for higher multiple coverings of curves, the case of double coverings being completely understood thanks to previous work by Duflot. In particular, we prove that every smooth curve can be covered with degree not too high by a smooth curve having arbitrarily large genus and surjective canonical Gaussian map. As a consequence, we recover an asymptoti...

We generalize the classical Terracini’s Lemma to higher order osculating spaces to secant varieties. As an application, we address with the so-called Horace method the case of the d-Veronese embedding of the projective 3-space. A.M.S. Math. Subject Classification (2000): 14N05.

Imaging devices operate at the physical interfaces corresponding to image capture and reproduction. The combination of physical insight and mathematical signal processing tools, therefore, offers unique advantages in solving problems in imaging systems. In this paper, we illustrate and support this idea using examples from our research on imaging, where the combination of physical insight, math...

College students, especially women, demonstrated negativity toward math and science relative to arts and language on implicit measures. Group membership (being female), group identity (self female), and gender stereotypes (math male) were related to attitudes and identification with mathematics. Stronger implicit math male stereotypes corresponded with more negative implicit and explicit math a...

Math can be difficult, and for those with high levels of mathematics-anxiety (HMAs), math is associated with tension, apprehension, and fear. But what underlies the feelings of dread effected by math anxiety? Are HMAs' feelings about math merely psychological epiphenomena, or is their anxiety grounded in simulation of a concrete, visceral sensation - such as pain - about which they have every r...
