Multiplicity result for mixed local and nonlocal Kirchhoff problems involving critical growth [PDF]
Opuscula MathematicaIn this paper, we study the multiplicity of nonnegative solutions for the following nonlocal elliptic problem \[\begin{cases}M\Big(\ \int_{\mathbb{R}^N}|\nabla u|^2dx+\iint_{\mathbb{R}^{2N}}\frac{|u(x)-u(y)|^2}{|x-y|^{N+2s}}dxdy\Big)\mathcal{L}(u ...

A Primer on Reliability via Coefficient Alpha and Omega
Archives of Psychology, 2019 Reliability is an important property to established for a measurement instrument. There are several types of reliabilities and each with its own purposes. However, whether warranted or not, internal consistency via coefficient alpha has been the standard for establishing the reliability of a measurement instrument for over 60 years. During this time,

The Logical Structure of Cronbach's Coefficient Alpha, and its Precision in Estimating Reliability under Measurement Models Assumptions. [PDF]
Journal of Islamic Studies, 2009 The study examined three main research questions: 1- What is the logical structure of Cronbach's Coefficient Alpha and its implications" 2- Under what measurement models and cicumstances the use of Coefficient Alpha produce either accurate or biased ...

Ω-results for sums of Fourier coefficients of cusp forms [PDF]
Acta Arithmetica, 1991 For a cusp form \(F(z)=\sum^{\infty}_{n=1}c(n)e^{2\pi inz}\) (c(n)\(\in {\mathbb{R}})\) of integral weight k for \(\Gamma_ 0(N)\) (for some integer \(N\geq 1)\) with real character, such that F(z) is an eigenfunction of the Hecke operators and does not vanish on \(\{\) iy ...

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.

Heat Transfer Performance in a Superheater of an Industrial CFBC Using Fuzzy Logic-Based Methods
Entropy, 2019 The heat transfer coefficient in the combustion chamber of industrial circulating flidized bed (CFB) boilers depends on many parameters as it is a result of multifactorial mechanisms proceeding in the furnace.

Utiliser le coefficient omega de McDonald à la place de l’alpha de Cronbach [PDF]
McGill Journal of Education, 2018 Des chercheurs discutaient récemment de l’importance de rester à jour au sujet des plus récentes avancées en méthodes quantitatives. À ce titre, de nombreux auteurs ont exposé leur souhait de voir les chercheurs abandonner le populaire coefficient alpha de Cronbach.
