A guide to exploratory structural equation modeling (ESEM) and bifactor-ESEM in body image research

open access: yesBody Image, 2023
Traditionally, assessments of factor validity of body image instruments have relied on exploratory or confirmatory factor analysis. However, the emergence of exploratory structural equation modeling (ESEM), a resurgence of interest in bifactor models, and the ability to combine both models (bifactor-ESEM) is beginning to shape the future of body image ...

Genetic analysis and fine mapping of the RK4 gene for round kernel in rice (Oryza sativa L.)

open access: yesCzech Journal of Genetics and Plant Breeding, 2017
Grain shape of rice is an important trait for both yield and quality. A rice rk4 (round kernel) mutant was obtained from the japonica variety Zhonghua 11 by radiation of 60Co-γ.

Validation of L2 grit among Chinese EFL high school students and its enduring effect on achievements: A bifactor model approach

open access: yesFrontiers in Psychology, 2022
The current study seeks to validate L2 grit measure among 637 Chinese senior middle school students using a bifactor modeling approach. To do so, we first assessed and compared four alternative measurement models including CFA, bifactor CFA, ESEM, and ...

Studies of unicellular micro-organisms Saccharomyces cerevisiae by means of Positron Annihilation Lifetime Spectroscopy [PDF]

open access: yes, 2015
Results of Positron Annihilation Lifetime Spectroscopy (PALS) and microscopic studies on simple microorganisms: brewing yeasts are presented. Lifetime of ortho - positronium (o-Ps) were found to change from 2.4 to 2.9 ns (longer lived component) for ...

Bifactor exploratory structural equation modeling: A meta-analytic review of model fit

open access: yesFrontiers in Psychology, 2022
Multivariate behavioral research often focuses on latent constructs—such as motivation, self-concept, or wellbeing—that cannot be directly observed. Typically, these latent constructs are measured with items in standardized instruments.

Transverse fracture properties of green wood and the anatomy of six temperate tree species [PDF]

open access: yes, 2016
© Institute of Chartered Foresters, 2016. All rights reserved. The aim of this study was to investigate the effect of wood anatomy and density on the mechanics of fracture when wood is split in the radial-longitudinal (RL) and tangential-longitudinal (TL)

Exploratory structural equation modeling: a streamlined step by step approach using the R Project software

open access: yesBMC Psychiatry, 2023
Confirmatory Factor Analysis (CFA) has been a popular yet limited approach to assessing latent factor structures. Despite items rarely loading exclusively on one latent factor in multifactorial scales, CFA assumes all indicators/items should load ...

An electron-induced secondary electron model for photoelectric sensitivity and quantum efficiency of metal surfaces

open access: yesResults in Physics, 2021
This paper studies an electron-induced secondary electron model ESEM for photoelectric sensitivity PS and quantum efficiency QE of metal surfaces near threshold frequency γ0, which was developed from Sommerfeld’s theory and the theories of transport and ...
