advancement in e-commerce technologies and emerge of web 2.0 applications developed e-commerce. nowadays, customers are entering new platform, where they are more active than before through participating in business process with the web 2.0 applications. by the impact of the new stream in e-commerce, social commerce, we propose and test an adoption model at the customer level. impact of social ...

Recent years, structural equation modelling (SEM) has become one of the most used multivariate data analysis techniques in information systems (IS) research. Although textbooks and guidelines on the application of SEM have been published, the increasing use of SEM in the domain calls for an updated review of its use within IS research. With this article, we aim to contribute to a more consisten...

Structural equation modeling using partial least squares (PLS-SEM) has become a main-stream modeling approach in various disciplines. Nevertheless, prior literature still lacks a practical guidance on how to properly test for differences between parameter estimates. Whereas existing techniques such as parametric and non-parametric approaches in PLS multi-group analysis solely allow to assess di...

Use of the partial least squares (PLS) method has been on the rise among e-collaboration researchers. It has also seen increasing use in a wide variety of fields of research. This includes most business-related disciplines, as well as the social and health sciences. The use of the PLS method has been primarily in the context of PLS-based structural equation modeling (SEM). This article discusse...

This study was an endeavor to develop a model of identity among Iranian EFL learners. To achieve this end, a multiphase design was implemented. Initially, it attempted to investigate different factors of identity to propose and validate a model. Thus, 120 EFL learners studying in different English language institutes in Iran were randomly selected, and 36 learners were interviewed about their v...

Obstructive sleep apnea (OSA), often concomitant with obesity, increases the risk for the metabolic syndrome. One mechanism that may participate in this association is upregulation of inflammatory pathways. We used structural equation modeling to assess the interrelations between childhood obesity, OSA, inflammation, and metabolic dysfunction. One hundred and eighty-four children (127 boys, mea...

regarding strategic importance of km, achieving to km objectives is difficult in practice and has faced with challenges. one of the major challenges is reluctance of users in kms acceptance and use. in this paper in order to exploitation of comprehensive model, effective factors of knowledge initiatives are extracted via mixed method in which systematic literature review along with open codding...

To reduce a large number of variables to a smaller number of factors for modeling purposes, where the large number of variables precludes modeling all the measures individually. As such, factor analysis is integrated in structural equation modeling (SEM), helping confirm the latent variables modeled by SEM. However, factor analysis can be and is often used on a stand-alone basis for similar pur...
