Das Ziel des Verbundvorhabens ist es, eine interaktive Software für die reflektierte Weitergabe von Gesundheitsdaten zu konzipieren, zu evaluieren und praktisch umzusetzen. Die Software regt eine persönliche Reflexion an, indem Patientinnen und Patienten das Spannungsfeld zwischen Datenschutz und -sicherheit und den Möglichkeiten einer verbesserten medizinischen Versorgung vor Augen geführt wird. Ausgangspunkt ist der Entscheidungsprozess der Datenweitergabe. https://www.interaktive-technologien.de/projekte/werteradar

Twin-singleton differences in IQ would be of concern for many groups, starting with parents of multiples and educators, up to behavioral geneticists (who depend on twin-singleton equivalence for generalizing twin study results to the general population) and cognitive epidemiologists (who investigate IQ associations with morbidity and mortality). It is thus unsurprising that twin-singleton differences in IQ have been investigated since the advent of twin studies and IQ test batteries (Merriman, 1924). We significantly update and expand the sole meta-analysis on this topic (Voracek & Haubner, 2008).
