This study highlights the importance of understanding the fair bidding behavior of bid practitioners in order to eliminate bid-rigging, which has a detrimental impact on the construction industry and the overall economy. The research collected survey data from bid practitioners in the Daegu and Gyeongbuk regions of South Korea and analyzed the causal relationships between attitudes towards bid-rigging, subjective norms, perceived behavioral control, and the intention to engage in fair bidding using PLS-SEM analysis. The analysis results confirm that attitudes towards bid-rigging and perceived behavioral control are significant variables predicting the intention to engage in fair bidding among bid practitioners. This indicates that bid practitioners' perceptions of bid-rigging and personal behavioral control influence their willingness and actions towards fair bidding. The insights gained from this research provide valuable insights into bid practitioners' behavioral changes and can aid in the development of policies and measures to promote fair bidding and prevent bid-rigging.

Online consumer reviews provide a variety of information from the customer perspective in terms of satisfaction and dissatisfaction. Negative emotional expression is a potential antecedent of review usefulness, and can also influence potential consumers' attitudes and decisions. In addition, because national culture provides a perspective from which individuals view the world and act, it is highly likely that differences in negative emotional expression will occur depending on culture. This study explores the relationship between national culture and negative emotional expression based on impression management theory and ultimately analyzes the impact on review usefulness. For empirical analysis, 16,076 reviews of 140 hotels located in Seoul were collected and analyzed using the PLS-SEM method. As a result of the analysis, it was found that power distance and masculinity culture dimensions had a positive effect on reviewers' negative emotional expressions, while uncertainty avoidance and long-term orientation had a negative effect. In addition, negative emotional expression was analyzed to have a positive effect on review usefulness even when review ratings were controlled.

This study aims to determine the perceptions of Islamic Financial Cooperative (BMT) managers in the Indonesian BMT Association on the acceptance of core banking technology. The Technology Acceptance Model (TAM) is used because it has simple theoretical characteristics (parsimony) and is supported by data (verifiability). This study develops the TAM model by integrating new variables -perceptions of maqashid sharia, perceptions of economies of scale, perceptions of market structure, and perceptions of technology procurement costs. These new variables are used to measure intention in using technology and actual usage in BMT operations. This study used PLS-SEM with smartPLS 3. The study was conducted in Central Java in six ex-Residency at 35 BMT with 300 respondents consisting of six levels of position level. The research found that maqashid sharia and market structure directly influenced the intention of BMT managers in using core banking technology. This new finding strengthens a theoretical model regarding the role of maqashid sharia in the acceptance of information technology in BMT. In addition, the perception of economies of scale has no significant effect on intention in using technology or its actual usage. The perception variable of technology procurement costs was found to have no significant effect on intention in using technology.

Purpose This study investigates the effects of trust and distrust on intention to purchase in open market, based on the idea that trust and distrust can co-exist. Specifically, this study approached the effects of trust and distrust of the open market on the intention to purchase from a two-dimensional perspective, and examined trustworthiness as the antecedents of trust and distrust. Design/Methodology/Approach In this study, we conducted a questionnaire survey on consumers who have actually purchased a product from open markets in Korea for two months. As a result, 141 users are chosen for the sample. We apply PLS (Partial Least Squares) structural equation modeling (SEM) to verify our theoretical model using the software application SmartPLS 3.0. Findings First, trust in open market positively affects intention to purchase, whereas distrust in open market negatively affects intention to purchase. Second, the three antecedents of trust (i.e. three factors constituting trustworthiness such as ability, benevolence and integrity) affect trust in open market. Third, integrity negatively affects distrust in open market. Since integrity plays an important role in building both trust and distrust in open market, the operators of open market should pay attention to managing their integrity.
