This tutorial introduces procedures and methods for performing structural equation modeling using R. To do this, we present advanced analysis methods based on structural equation model such as mediation effect analysis, moderation effect analysis, moderated mediation effect analysis, and multiple-group analysis with R program code using R lavaan package that supports structural equation modeling. R is flexible and scalable, unlike traditional commercial statistical packages. Therefore, new analytical techniques are likely to be implemented ahead of any other statistical package. From this point of view, R will be a very appropriate choice for applying new analytical techniques or advanced techniques that researchers need. Considering that various studies in the social sciences are applying structural equations modeling techniques and increasing interest in open source R, this tutorial is expected to be useful for researchers who are looking for alternatives to existing commercial statistical packages.

Purpose: The aim of this study was to examine the relationship between handwashing knowledge and handwashing compliance in nursing students and to identify the moderation and mediation effects of self-efficacy and perceived behavioral control on the relationship. Methods: The participants were 172 nursing college students who completed the self-report measures. Data were analyzed using t-test, ANOVA, and Pearson correlation coefficient, Multiple regression analysis was used to test moderation and mediation effects. Results: The score for knowledge of handwashing was higher in participants who had completed fundamentals of nursing practicum (t=-6.54, p<.001) and the score for compliance with handwashing was higher in participants who had completed clinical practicum (t=-3.81, p<.001) or fundamentals of nursing practicum (t=-5.97, p<.001). Self-efficacy showed a significant moderation effect (z=2.21, p=.027) but not a mediation effect while perceived behavioral control had a significant mediation effect but not a moderation effect on the relationship between knowledge of handwashing and compliance. Conclusion: Findings indicate that clinical practicum and fundamentals of nursing practicum were helpful to nursing students in acquiring knowledge and in practicing proper handwashing technique. These findings suggest that continuing and repetitive education programs on handwashing need to be enhanced and strategies to strengthen self-efficacy and perceived behavioral control need to be included in education programs.

According to adaptive structuration theory, faithfulness of appropriation(FOA), and consensus on appropriation(COA) are variables for measuring appropriation in use of IT. FOA is the level of interpreting and using the intentions of the IT designers objectively and COA is the level of agreement on ways of using IT among or with user group independently of designers' intention. In traditional theories of IT adoption, computer self-efficacy(CSE), self evaluation on abilities of using computer, has been considered as one of the important individual differences. which would influence on beliefs of using IT. Therefore, considering the relationship among CSE, FOA, COA and attitude, we can hypothesize that CSE would play a moderation varaible among appropriation related variables relationships, FOA-attitude and COA-attitude. The objective of this study is an analysis of CSE's moderation effects in causality relationship among appropriation measuring variables. For this purpose, we propose a research model where there are four hypotheses for moderation effects of CSE on the relationships between appropriation variables. We test these hypotheses by sampling ERP and groupware users. In result, our proposed hypotheses except moderation effect of COA-usefulness are accepted. Main contribution of this study is to identify the relationship between CSE and AST. This study implies that very careful consideration of users' CSE is necessary in order to perform managerial activities based on FOA and COA in IT management department.

This study investigates the effect of shareholders' rights, disclosure, and transparency on firm value. This study also investigates whether corporate social responsibility (CSR) is pure moderation or quasi moderation in the effect of shareholders' rights, disclosure, and transparency on firm value. This study's novelty is building a model framework to increase firm value and the role of CSR in increasing firm value. This study used secondary data provided by Indonesia, Malaysia, and Thailand Stock Exchanges. The sample of this study is 142 companies with four years of observations from 2012-2015. Firm value is measured by Tobin's Q. While shareholder's rights, disclosure, and transparency are measured using the ASEAN scorecard. The analysis method used in this study is a fixed effect model using a panel data approach. The result of this study shows that shareholders' rights have a significant positive effect on firm value. However, disclosure and transparency do not affect firm value significantly. In comparison, the CSR disclosure has a moderation effect on the relationship between shareholders' rights and firm value. The CSR disclosure does not have a moderation effect on the relationship between disclosure and transparency and firm value.

Online consumer reviews (OCRs) provide product information and recommendations especially pictures in reviews depict the true information about the product. This study investigates the influence of pictured reviews on online seller (for a particular product of a seller) rating with moderating effect of price, brand type (foreign vs local), goods type (experience vs search), and brand familiarity. Multiple robust linear regression analysis with moderation interaction and quadratic effect used to explain the relationship of the explanatory variables with the criterion variable. We collected cross-sectional data from the two most renowned Chinese online shopping platforms (B2C) of total 15,621 product links. Results show that higher number of reviews with a low ratio of picture reviews response negative effect on rating, whereas the lower number of reviews with a high ratio of picture reviews response positive effect on the rating. In overall picture in the reviews improve the online seller product rating. For the moderation effect, results show that price and brand familiarity have a positive interaction effect on the relation of pictured reviews and rating whereas experience goods have less negative effect comparing search goods. Finally, local brand has less negative interaction effect comparing foreign brand to pictured reviews and rating.
