Researchers Discover How Spelling Errors Slow Down Reading in Russian
Psycholinguists from the Centre for Language and Brain at HSE University–St Petersburg have shown that words that are frequently misspelled are processed more slowly by readers, even when presented with the correct spelling. The researchers confirmed this effect for the first time using Russian-language materials and found that response speed is most strongly linked to how confidently individuals can distinguish the correct spelling of a word from an incorrect one. The study has been published in The Mental Lexicon.

HSE Develops App for Assessing Phonological Processing in Children
Researchers at the HSE Centre for Language and Brain have developed a new digital tool for assessing children's phonological processing skills—the ZARYA (Sound Analysis of the Russian Language) test battery. It is the first standardised application in Russia designed to provide a fast and reliable assessment of children's ability to distinguish speech sounds, retain them in working memory, and perform phonemic analysis. The app runs on Android tablets and smartphones and is available for download from RuStore. Details of the test validation have been published in the Journal of Speech, Language, and Hearing Research.

Scientists Discover Why Europium 'Misbehaves'
Europium is a rare-earth metal responsible for the pure red glow in displays and other luminescent materials. For a long time, however, it refused to emit light when surrounded by certain organic molecules known as acylpyrazolone ligands. Chemists have now uncovered the reason: in europium complexes with these ligands, a 'black window' appears—a charge-transfer state in which the energy absorbed by the ligand is dissipated as heat rather than emitted as light. Understanding this mechanism opens the way to designing more efficient red-emitting materials for displays, fluorescent thermometers, and chemical sensors. The results have been published in Dalton Transactions.

The impact of data frequency on performance measures

P. 495–504.
Parshakov P., Semushin A.

We focus on correlation between the estimates of manager's skills to invest and the frequency of measurement results ob¬tained by them, which can lead to distortion of investment decisions. We found that estimates of performance measures depend not only on the frequency of observations, but on its relationship with the frequency of the transactions of the fund. тайминг; селектинг; частота наблюдений market timing; selectivity skills; data frequency

Влияние частоты данных на оценки показателей эффективности управляющих активами
Parshakov P., Semushin A., Прикладная эконометрика 2012 № 1 С. 95–114
В статье проводится анализ зависимости оценок показателей эффективности управляющих активами от частоты используемых данных. Моделируя искусственных управляющих через задание их навыков, авторы пришли к выводу, что между частотой наблюдений и итоговыми результатами есть связь. При этом оценки мер эффективности зависят не столько от самой частоты наблюдений, сколько от ее соотношения с частотой совершения операций фондом. ...
