Abstract
Purpose
Source factors have long been a key construct in studies of word-of-mouth influence, but particularly for the digital context of electronic word-of-mouth (eWOM), source trustworthiness and parasocial relationships are worth a considerable focus. This study pays close attention to not only the effects source trustworthiness and parasocial relationships exert on eWOM influence but also the antecedents driving them. This study additionally considers the moderating role of brand credibility in the relationships between the two key constructs and eWOM influence. Confirmatory factor analysis (CFA) was conducted to assess the reliability and validity of the constructs.
Design/methodology/approach
A quantitative survey was sent to university students in Ho Chi Minh City, Vietnam, to collect 766 responses, which were then analyzed using an SEM approach. The sampling strategy was based on convenience and snowball sampling techniques to ensure a diverse representation of the student population. Respondents were asked to rate their perceptions of source trustworthiness, parasocial relationships, brand credibility, and eWOM influence regarding social media influencers they follow. The collected data were then analyzed using an SEM approach, utilizing software such as AMOS to validate the measurement model and test the proposed structural relationships.
Findings
The results confirm the strong impact of source trustworthiness and parasocial relationships on eWOM influence and recognize source authenticity to be the most powerful driver behind the two. Additionally, the findings suggest that brand credibility can positively moderate how source trustworthiness affects eWOM influence, with interaction effects examined through multi-group analysis.
Originality/value
Relevant implications for researchers and marketing practitioners are discussed, emphasizing the strategic selection of eWOM sources and the cultivation of brand credibility to enhance consumer engagement.

Abstract
Purpose
This study aims to examine the relationship between key audit matters (KAMs) and the restatement of financial statements, assessing their impact on the financial statement restatement process.
Design/methodology/approach
This study aims to examine the economic context of Vietnam by analyzing data from 170 listed enterprises on the Vietnam stock exchange from 2010–2021. Feasible generalized least squares and robustness regression are conducted to give results and conclusions.
Findings
The results show that the KAMs disclosure in the financial statements has not really significantly affected the quality of an audit, so the KAMs disclosure does not have too much impact on the restatement of financial statements. However, this study found that the number of disclosed KAMs would partly reflect the shortcoming that exists in companies' financial statements.
Practical implications
The authenticity of financial statements is crucial for companies to meet auditor requirements, particularly KAMs. Restatements can influence business decisions and provide more accurate financial information to stakeholders. Thus, studying the impact of KAMs on restatement is essential for improving the veracity and reliability of financial statements.
Originality/value
This study clarifies the important role of KAMs in financial statements to recommend investors to be more careful in considering KAMs disclosed by auditors in audit reports. In addition, this study helps to add an overview of KAMs in emerging markets like Vietnam, as well as helps stakeholders to improve the legal system on Accounting – Auditing in Vietnam.

Abstract
Purpose
Corrosion of steel in marine environments poses a significant economic and environmental challenge because of its detrimental effects on marine structures and equipment. Traditional chemical inhibitors that mitigate corrosion often introduce harmful substances into the environment. As a result, there is a growing interest in exploring eco-friendly alternatives, such as plant-derived inhibitors, to reduce the environmental impact of corrosion protection strategies. The purpose of this study is to investigate the effectiveness of Phyllanthus urinaria extract as a green anti-corrosion additive for rebar steel in marine conditions.
Design/methodology/approach
Phyllanthus urinaria extract was prepared in the ethanol solution with the assistance of a sonicator. The steel’s surface upon addition of the extract was characterized using SEM, EDX and FTIR analysis. The electrochemical corrosion characteristics, including potentiodynamic polarization and electrochemical impedance spectroscopy, were used to evaluate the inhibitory performance of the extract on steel under simulated marine conditions (3.5% NaCl solutions).
Findings
The results of this study showed that with Phyllanthus urinaria extract’s content of 0.02% in NaCl solution of 3.5%, the corrosion rate decreased to about 30% compared to the controlled sample. Measurements of the inhibitory mechanism analysis study for all solutions from 0 mg/L to 1.114 mg/L of polyphenol from Phyllanthus urinaria extract showed a significant reduction in rebar corrosion rate, especially with 0.2228 mg/L polyphenol. Reinforcement can increase corrosion inhibition by up to 30% compared to the control sample.
Originality/value
To the best of the authors’ knowledge, this is the first study of using Phyllanthus urinaria extract as green inhibitor for protection of steel from the corrosion in the simulated marine solution. The protective mechanism for steel using Phyllanthus urinaria extract was investigated using the FTIR, SEM, EDX and electrochemical analysis. The results indicated that the polyphenols in the extract showed inhibition that could minimize the corrosion of reinforcement in marine environments.

Abstract
Purpose
This paper, drawing on self-enhancement theory and from employee perspective, aims to develop and validate an integrative theoretical model that centers on the trust–psychological ownership (PO) link to investigate information and communications technology (ICT) employee work outcomes.
Design/methodology/approach
A cross-sectional survey with PLS-SEM analysis of 424 employees in ICT industry in Ho Chi Minh City, Vietnam, reports that all of 10 hypotheses are empirically supported.
Findings
PO is found to be an important driver of employee flow, job performance and psychological wellbeing. Moreover, it is posited that trust acts a moderator of the relationship between flow experience and job performance, and between job performance and psychological wellbeing.
Originality/value
To the best of the authors’ knowledge, this paper is among the first to affirm that trust in work environment serves as both an enabler for PO and a moderator for the relationship between flow experience–job performance as well as between job performance–psychological wellbeing path. The study also affirms that flow state plays a mediating role in the PO–job performance path, and that job performance acts as a mediator in the flow experience–psychological wellbeing sequence. Finally, new evidence expectedly highlights the positive impact of job performance, a short-term work outcome, on psychological wellbeing, a long-term work outcome.

This study examines the influence of stock liquidity on stock price crash risk and the moderating role of institutional blockholders in Vietnam’s stock market.
Abstract
Purpose
This study examines the influence of stock liquidity on stock price crash risk and the moderating role of institutional blockholders in Vietnam’s stock market.
Design/methodology/approach
Crash risk is measured by the negative coefficient of skewness of firm-specific weekly returns (NCSKEW) and the down-to-up volatility of firm-specific weekly stock returns (DUVOL). Liquidity is measured by adjusted Amihud illiquidity. The two-stage least squares method is used to address endogeneity issues.
Findings
Using firm-level data from Vietnam, we find that crash risk increases with stock liquidity. The relationship is stronger in firms owned by institutional blockholders. Moreover, intensive selling by institutional blockholders in the future will positively moderate the relationship between liquidity and crash risk.
Practical implications
Since stock liquidity could exacerbate crash risk through institutional blockholder trading, firm managers should avoid bad news accumulation and practice timely information disclosures. Investors should be mindful of the risk associated with liquidity and blockholder trading.
Originality/value
We contribute to the literature by showing that the activities of blockholders could partly explain the relationship between liquidity and crash risk. High liquidity encourages blockholders to exit upon receiving private bad news.

Abstract
Purpose
This study aims to examine the relationship between a team’s value diversity (VD) and creativity and investigate the moderating effect of emotional intelligence (EI) to explain inconsistent results regarding this relationship.
Design/methodology/approach
We conducted a cross-sectional sequential study with 340 employees and tested the hypothesis in a laboratory setting with 180 undergraduate students.
Findings
EI had a moderating effect on the relationship between a team’s VD and creativity in that the relationship was positive among teams with high EI. However, the relationship tended to be negative in the long term among teams with low EI.
Practical implications
Managers should pay attention to how teams benefit from VD because it can help or harm team performance. By assigning people with different EI levels into suitable teams and providing EI interventions, organizations may manage affective consequences and enjoy more benefits of cognitive consequences resulting from VD.
Originality/value
No previous study has investigated the effect of a team’s EI in the relationship between VD and team creativity. Drawing on the categorization-elaboration model of diversity and affective events theory, through the present two-study design, we obtained data from multiple sources and improved limitations in measurements of previous studies, thereby broadening the literature by highlighting the dynamic relationship between a team’s EI, VD and creativity in the Vietnamese context.

Abstract
Purpose
In the apparel industry, suppliers play a significant role, directly affecting customer service levels and business profits. Integrating sustainable requirements into supplier selection not only aligns with global environmental goals but also enhances business performance, social responsibility and overall industry well-being. This study aims to design a multi-criteria model to evaluate and select the most sustainable suppliers in the fashion industry, trying to balance the conflicts in the set of sustainable development criteria.
Design/methodology/approach
The integration of analytic hierarchy process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) offers advantages in sustainable supplier selection within the apparel industry. The AHP plays a crucial role in engaging multiple decision-makers with conflicting criteria to reach a consensus during the decision-making process. Conversely, the TOPSIS is used to compute alternative ratings. By simultaneously determining criteria weights and incorporating stakeholder preferences, hybrid models enhance decision-making strength and overcome limitations observed in classical multi-criteria decision-making techniques.
Findings
This research identified and classified 16 critical criteria impacting the selection of apparel industry suppliers, focusing on sustainable development. The criteria were weighted, providing a robust statistical foundation for the selection model. The results indicated that the most influential criteria were staff training, production capability, flexibility and practice of recycling. The proposed sustainable supplier selection model explains to decision-makers how criteria influence supplier ranking results compared to traditional models, supporting managers in making informed and sustainable supply chain decisions through continuous updates and enhancements.
Originality/value
This research provides new insight into the weighted impact of factors related to sustainable supplier selection in the apparel industry. The combination of a precise process and scientific knowledge will improve the quality of sustainable supplier selection.
