This study analyzes the various roles of social value in the consumption value model in China's mobile e-commerce environment. This is because customers in the Confucian culture area are highly influenced by others in their consumption behavior. However, there has been no consideration of these opinions in the consumption value model. In particular, it was analyzed whether social value has a moderated mediation effects in the path of economic value on customer loyalty. As a result of analyzing 228 pieces of data collected in China, it was found that the economic value is increasing customer loyalty through the entrance of shopping malls, and this indirect effect is affected by social value, and there was a moderated mediation effect. This study is theoretically meaningful in that it is newly elucidating the role of social value in the consumption value model.

This study examines the mediation effect of teacher-child interactions in the process of the impact of teacher's teaching-efficacy on childhood education institutions and classroom environment on peer-play interactions. We used data from 970 children aged between 49 and 55 months and 970 homeroom teachers from the fifth Korean Child Panel (2012) of the Korea Institute of Child Care and Education. The model fitness was excellent after data were statistically analyzed with model of structure to testify the relationship and effect among teaching efficacy, classroom environment, teacher-child interactions, and peer-play interactions. First, the analysis also showed that the teacher's teaching efficacy did not influence peer-play interactions directly, but gave an indirect effect on the peer-play interactions with the mediation of the teacher-child interactions. Second, the classroom environment directly and indirectly influenced the peer-play interactions with the mediation of the teacher-child interactions. Third, the variable of teacher-child interactions was fully effective as a mediating variable in the process of the teaching efficacy and classroom environment influence on teacher-child interactions. Teaching efficacy and classroom environment influenced the peer-play interactions through the mediation of the teacher-child interactions. The significance of mediation effect of the teacher-child interactions was verified through a bootstrapping method.

Purpose: This study was done to develop a prediction model for postpartum depression by verifying the mediation effect of antepartum depression. A hypothesized model was developed based on literature reviews and predictors of postpartum depression by Beck. Methods: Data were collected from 186 pregnant women who had a gestation period of more than 32 weeks and were patients at a maternity hospital, two obstetrics and gynecology specialized hospitals, or the outpatient clinic of K medical center. Data were analysed with descriptive statistics, correlation and exploratory factor analysis using the SPSS/WIN 18.0 and AMOS 18.0 programs. Results: The final modified model had good fit indices. Parenting stress, antepartum depression and postpartum family support had statistically significant effects on postpartum depression, and defined 74.7% of total explained variance of postpartum depression. Antepartum depression had significant mediation effects on postpartum depression from stress in pregnancy and self-esteem. Conclusion: The results of this study suggest that it is important to develop nursing interventions including strategies to reduce parenting stress and improve postpartum family support in order to prevent postpartum depression. Especially, it is necessary to detect and treat antepartum depression early to prevent postpartum depression as antepartum depression can affect postpartum depression by mediating antepartum factors.

This study postulates a partial mediation model(study model I) and a whole mediation model(study model II) to examine the effect on endogenous rural development of local innovation capability strengthening in the local industry promotion project, the establishment of promotion system, and the revitalization of local economy. To accomplish study purposes, 169 response samples from 85 project groups which drive the local industry promotion project were verified using SPSS 12.0 and AMOS 5.0. The results showed that in the partial mediation model, the local innovation capability strengthening had a significantly positive effect on the establishment of promotion system, the establishment of promotion system had a significant effect on the revitalization of local economy, and the revitalization of local economy had a significant effect on the endogenous rural development, while the establishment of promotion system and local innovation capability strengthening didn't have effect on the endogenous rural development. In the whole mediation model, the local innovation capability strengthening had a significant effect on the revitalization of local economy, the establishment of promotion system on the revitalization of local economy, and the revitalization of local economy on the endogenous rural development. According to the verifications of study model I and II, the endogenous rural development is achieved after the revitalization of local economy through the establishment of promotion system and the local innovation capability strengthening. From these results, this study presents suggestions, limits of study and directions in the future study.

This study aimed to clarify the continuance intention of users of size recommendation services. The expectation-confirmation model framed the analysis of the 180 data points collected. The analysis determined the mediating effects of perceived usefulness and satisfaction on the relationship between expectation-confirmation and continuance intention. The moderated mediation effect of familiarity was also analyzed, and a path analysis was conducted using PROCESS macro. Results showed that expectation-confirmation had a significant effect on perceived usefulness, satisfaction, and continuance intention. Findings indicated that perceived usefulness affected satisfaction and continuance intention and confirmed that satisfaction affected continuance intention. In the relationship between expectation-confirmation and continuance intention, mediation analysis verified the mediation and double mediation of perceived usefulness and satisfaction. In the group with an above-average familiarity value, moderation analysis confirmed a moderating effect between perceived usefulness and satisfaction. Above-average familiarity values also confirmed that the moderating effect on continuance intention was significant.

This study aimed to identify the multiple mediation effects of job satisfaction and job commitment on the relationships between job stress and workers' safety behavior in terms of compliance and participation, in which the multiple mediation effects are a hybrid of parallel and serial mediating relationships. The multiple mediation model was analyzed using the bootstrapping method through the PROCESS macro tool in SPSS. The results showed that job stress negatively affects job satisfaction, job commitment, and workers' safety behavior, and the relationship between job stress and safety behavior is mediated by both job satisfaction and job commitment. The serial mediation effects of job satisfaction and job commitment were also found to be statistically significant in the regression relationship between job stress and safety behavior. Further analysis of the compliance and participation subdimensions of safety behavior showed similar results. Specifically, the serial mediation effects of job satisfaction and job commitment on participation and compliance behavior were further supported; however, the mediation effect of job satisfaction was not significant, whereas that of job commitment did remain significant. Further research is needed to determine if the mediation effect of job satisfaction found in this study can be extended and generalized to workers in various fields and industries.

Purpose - This paper is an empirical investigation of the mediation effect of innovation activity in industry transformation considering the relationship between the semiconductor industry and high-quality economic development. The research questions are whether the semiconductor industry drives high-quality economic development and if so, what is the semiconductor industry's role in high-quality development? We found that the semiconductor industry has clearly improved the quality of economic development, and its comparative advantage has significantly increased per capita national incomes. Furthermore, innovation activity proved to be an intermediary factor for the semiconductor industry to promote high-quality economic development. The world economy should aim to reasonably develop the international semiconductor industry and cultivate innovation markets. Design/methodology - Our empirical model considers the relationship between the semiconductor industry, innovation activity, and high-quality economic development. We constructed an analysis framework based on data from 199 World Bank economies between 1995 and 2019, and we used a mediation effect method to calculate the total effect of the semiconductor industry on promoting high-quality economic development, the indirect effect of the semiconductor industry on promoting innovation activity, and the mediation effect of these innovation activities on the promotion of high-quality economic development. Findings - The results show that the semiconductor industry has significantly promoted high-quality economic development. This is true even after the robustness test of grouping and alternative variables was applied. An analysis of the mechanism shows that promoting patents, scientific research, efficient government, and urban management innovation are important mechanisms for the semiconductor industry to release high-quality development dividends. Originality/value - Although it has been shown that specific industries like semiconductors can affect high-quality economic development through industrial upgrading, few researchers have attempted to empirically test the impact of the semiconductor industry on high-quality economic development. In this paper, we use a mediation effect model, alternative variables and a grouping test to find the internal mechanisms of the comparative advantage of the semiconductor industry in high-quality economic development from the perspective of innovation activity.

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.
