Typology of Deflation-Corrected Estimators of Reliability

open access: yesFrontiers in Psychology, 2022
The reliability of a test score is discussed from the viewpoint of underestimation of and, specifically, deflation in estimates or reliability. Many widely used estimators are known to underestimate reliability.

Reliability Estimation in Multidimensional Scales: Comparing the Bias of Six Estimators in Measures With a Bifactor Structure

open access: yesFrontiers in Psychology, 2021
In the context of multidimensional structures, with the presence of a common factor and multiple specific or group factors, estimates of reliability require specific estimators. The use of classical procedures such as the alpha coefficient or omega total

Existence and exact multiplicity of positive periodic solutions to forced non-autonomous Duffing type differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
The paper studies the existence, exact multiplicity, and a structure of the set of positive solutions to the periodic problem $$ u''=p(t)u+q(t,u)u+f(t);\quad u(0)=u(\omega),\ u'(0)=u'(\omega), $$ where $p,f\in L([0,\omega])$ and $q\colon[0,\omega ...

Omega-3 fatty acids in bipolar patients with a low omega-3 index and reduced heart rate variability: the “BIPO-3” trial

open access: yesInternational Journal of Bipolar Disorders, 2022
Background Research suggests that a low omega-3 index may contribute to the low heart rate variability and the increased risk of cardiovascular morbidity and mortality in bipolar disorders. However, so far, no intervention trial with EPA and DHA has been
