Your Coefficient Alpha Is Probably Wrong, but Which Coefficient Omega Is Right? A Tutorial on Using R to Obtain Better Reliability Estimates [PDF]
Advances in Methods and Practices in Psychological Science, 2020 Measurement quality has recently been highlighted as an important concern for advancing a cumulative psychological science. An implication is that researchers should move beyond mechanistically reporting coefficient alpha toward more carefully assessing the internal structure and reliability of multi-item scales.

Electronic Journal of Differential Equations, 2022 In this article, we study (omega, c)-periodic solutions for non-instantaneous impulsive systems and the time-varying coefficient A(t) is a family of unbounded linear operators. We show the existence and uniqueness of (omega, c)-periodic solutions using a fixed point theorem. An example is given to illustrate our results.

Critical and non-critical jamming of frictional grains [PDF]
, 2006 We probe the nature of the jamming transition of frictional granular media by studying their vibrational properties as a function of the applied pressure p and friction coefficient mu. The density of vibrational states exhibits a crossover from a plateau

Une note sur le coefficient oméga (ω) et ses déclinaisons pour estimer la fidélité des scores
Mesure et Évaluation en Éducation, 2020 Au cours des dernières décennies, certains auteurs ont suggéré de rejeter le coefficient alpha (α) de Cronbach (1951) pour adopter le coefficient oméga (ω) de McDonald (1985, 1999) basé sur un modèle d’analyse factorielle.

Boundary Value Problems, 2021 A priori bounds were derived for the flow in a bounded domain for the viscous-porous interfacing fluids. We assumed that the viscous fluid was slow in Ω 1 $\Omega _{1}$ , which was governed by the Boussinesq equations.
