Informationsund Kommunikationstechnik nimmt eine ständig wachsende Rolle im Automobil ein. Der vorliegende Artikel soll das erste Mal einen Überblick über den wichtigen Themenkreis der IT-Sicherheit im Automobil geben. Es werden die jetzigen und zukünftigen Automobilfunktionen mit Sicherheitsbedarf diskutiert, eine Bedrohungsanalyse erstellt und Besonderheiten der eingebetteten Sicherheit im Au...

Lebensmittelskandale haben in der Agrarund Ernährungsindustrie zu Rückverfolgbarkeitslösungen unterschiedlichster Ausprägung geführt. Empirische Aussagen über die Relevanz einzelner Kostenbzw. Nutzenaspekte der Stakeholder von IT-basierten Qualitätssicherungsund Rückverfolgbarkeitssystemen liegen derzeit nicht vor. Ziel des Forschungsvorhabens ist daher die Identifizierung und Quantifizierung d...

Singaporean elementary-school students (N 1⁄4 299) completed Child Implicit Association Tests (Child IAT) as well as explicit measures of gender identity, mathegender stereotypes, and math self-concepts. Students also completed a standardized math achievement test. Three new findings emerged. First, implicit, but not explicit, math self-concepts (math 1⁄4 me) were positively related to math ach...

There is a growing literature concerning the role of the home math environment in children's math development. In this study, we examined the relation between these constructs by specifically addressing three goals. The first goal was to identify the measurement structure of the home math environment through a series of confirmatory factor analyses. The second goal was to examine the role of th...

Previous research has shown that math anxiety can influence the math performance level; however, to date, it is unknown whether math anxiety influences performance on working memory tasks during neuropsychological evaluation. In the present study, 172 undergraduate students completed measures of math achievement (the Math Computation subtest from the Wide Range Achievement Test-IV), math anxiet...

This study investigated the role of strategy instruction and working memory capacity (WMC) on problem solving solution accuracy in children with and without math disabilities (MD). Children in grade 3 (N = 204) with and without MD subdivided into high and low WMC were randomly assigned to 1 of 4 conditions: verbal strategies (e.g., underlining question sentence), visual strategies (e.g., correc...

The cognitive literature now shows how critically math performance depends on working memory, for any form of arithmetic and math that involves processes beyond simple memory retrieval. The psychometric literature is also very clear on the global consequences of mathematics anxiety. People who are highly math anxious avoid math: They avoid elective coursework in math, both in high school and co...

Mathematical competence requires pattern recognition for appropriate application of concepts and procedures. Research demonstrates that interventions targeting perceptual learning (PL) improve math performance. Little research, however, has directly investigated encoding changes, measured psychophysically, that may accompany PL gains in real-world tasks. We sought evidence of lasting encoding c...

Results from a controlled evaluation of remedial reading interventions are reported: 279 young disabled readers were randomly assigned to a program according to a 2 × 2 × 2 factorial design (IQ, socioeconomic status [SES], and race). The effectiveness of two multiple-component intervention programs for children with reading disabilities (PHAB + RAVE-O; PHAB + WIST) was evaluated against alterna...
