Is the d2 Test of Attention Rasch Scalable? Analysis With the Rasch Poisson Counts Model [PDF]

Perceptual and Motor Skills, 2018
The d2 test is a cancellation test to measure attention, visual scanning, and processing speed. It is the most frequently used test of attention in Europe. Although it has been validated using factor analytic techniques and correlational analyses, its fit to item response theory models has not been examined.

Separation und Valorisierung von Chlor aus Restgasströmen

Angewandte Chemie, EarlyView.
Es wurde festgestellt, dass ein handelsübliches Ionenaustauscherharz in Gegenwart anderer Gase selektiv Chlorgas adsorbiert und dabei reversibel die entsprechenden Trichlorid‐Spezies [IEx][Cl3] bildet. Diese Entdeckung wurde zu einem effizienten Verfahren für die Rückgewinnung und Verwertung von Chlor aus industriell reichlich vorhandenen ...

The Role of Syllables in Anagram Solution: A Rasch Analysis [PDF]

The Journal of General Psychology, 2011
Anagrams are frequently used by experimental psychologists interested in how the mental lexicon is organized. Until very recently, research has overlooked the importance of syllable structure in solving anagrams and assumed that solution difficulty was mainly due to frequency factors (e.g., bigram statistics).

Ein Ruthenium(CAAC‐5)‐Olefin‐Metathese‐Katalysator für die Biokonjugation

Angewandte Chemie, EarlyView.
Die Instabilität von Rutheniumkatalysatoren in wässrigen Lösungen schränkt die Olefinmetathese in biologischen Medien ein. Es wird über einen Ru(CAAC‐5)‐Komplex berichtet, der unter biologisch relevanten Bedingungen aktiv bleibt und die Biokonjugation mit Proteinen, Peptiden und einem künstlichen Metalloenzym ermöglicht.
