For the past decade, the convenience of sharing information online has improved drastically with the development of smart devices and social media. Such changes have contributed to regarding online word-of-mouth (WOM) as one of the most important consumer information sources. Therefore, the purpose of this study is to examine online WOM effects (acceptance/redelivery intention) with the two-way interaction effects of fashion involvement and the market maven. The empirical study consisted of an offline survey that collected data from 341 respondents and analyzed the data by factor analysis, independent t-test, and two-way ANOVA with SPSS 20.0, producing the following results. First, the market maven effect was found to differ significantly based on the level of fashion involvement, and is also higher when fashion involvement is high. Second, fashion involvement primarily affected online WOM acceptance, while the market maven significantly affected redelivery intention. Moreover, fashion involvement and market maven had relevant two-way interaction with both of the online WOM effects. Third, market maven had measurable effects on WOM redelivery types (objective/subjective) and directions (positive/negative/ neutral), whereas fashion involvement did not have any primary effects on them. However, fashion involvement and market maven had two-way interaction effects on the positive and negative direction of WOM redelivery. Based on these findings, the study suggests the importance of investigating and understanding the complicated online WOM behaviors of consumers, specifically from both managerial and theoretical perspectives.

The main objective of this paper is to examine the applicability of Linan and Chen's entrepreneurial intention model (EIM) in predicting the entrepreneurial intention. EIM is an adaptation of the Theory of Planned Behavior that focuses on entrepreneurial intention and hypothesizing slightly different patterns of relationship with regards to subjective norms. The model also includes human capital and demographic factors. Snowball sampling method was used to collect data using the entrepreneurial intention questionnaire (EIQ) through several social media platforms. The survey indicates that the overall entrepreneurial intention of Saudi students is high (mean = 5.41). Eight out of the seventeen hypothesized relationships were found to be significant. Among the demographic variables, gender-personal attitude was significant whereas self employment experience and years of business education were found to be significantly related with perceived behavioral control. The statistical analysis using partial least square structural equation modelling validated the model. All the three antecedents of entrepreneurial intention were significantly related with entrepreneurial intention. The results of this study will help policy makers to get deep understanding into the phenomenon of entrepreneurship among Saudi university students and thereby develop a conducive environment. This study also validates the entrepreneurial intention model in a different cultural context.

Objectives: The aim of this in vitro study was to evaluate the biocompatibility of newly proposed root-end filling materials, Biodentine, Micro-Mega mineral trioxide aggregate (MM-MTA), polymethylmethacrylate (PMMA) bone cement, and Smart Dentin Replacement (SDR), in comparison with contemporary root-end filling materials, intermediate restorative material (IRM), Dyract compomer, ProRoot MTA (PMTA), and Vitrebond, using human periodontal ligament (hPDL) fibroblasts. Materials and Methods: Ten discs from each material were fabricated in sterile Teflon molds and 24-hour eluates were obtained from each root-end filling material in cell culture media after 1- or 3-day setting. hPDL fibroblasts were plated at a density of $5{\times}10^3/well$, and were incubated for 24 hours with 1:1, 1:2, 1:4, and 1:8 dilutions of eluates. Cell viability was evaluated by XTT assay. Data was statistically analysed. Apoptotic/necrotic activity of PDL cells exposed to material eluates was established by flow cytometry. Results: The Vitrebond and IRM were significantly more cytotoxic than the other root-end filling materials (p < 0.05). Those cells exposed to the Biodentine and Dyract compomer eluates showed the highest survival rates (p < 0.05), while the PMTA, MM-MTA, SDR, and PMMA groups exhibited similar cell viabilities. Three-day samples were more cytotoxic than 1-day samples (p < 0.05). Eluates from the cements at 1:1 dilution were significantly more cytotoxic (p < 0.05). Vitrebond induced cell necrosis as indicated by flow cytometry. Conclusions: This in vitro study demonstrated that Biodentine and Compomer were more biocompatible than the other root-end filling materials. Vitrebond eluate caused necrotic cell death.
