This paper aims to explore the influence of the COVID-19 outbreak and the Government's disease control measures on the stock returns and liquidity of Vietnam-listed companies in the financial services sector.

The authors have conducted a panel data regression analysis using data from 50 banking, insurance and finance companies listed in Vietnam's two biggest stock exchanges (HNX and HOSE) within the period from January 30th, 2020 to May 15th, 2021.

The regression results indicate that the daily growth in the total number of confirmed cases caused by COVID-19 has significant negative effects on the stock market returns and liquidity. Nevertheless, the Government's imposition of lockdown yields significant and positive outcomes on stock performance. In addition, the study reveals remarkable differences in returns of large-cap and small-cap stocks under the impact of the COVID-19 pandemic.

The study indicates government and regulators should act more actively to limit the outbreak of the virus, improve investor confidence as well to support the financial services industry and deal with the outbreak of the pandemic later.

This is the first study to explore the influence of the COVID-19 outbreak and the Government's disease control measures on the stock returns and liquidity of Vietnam-listed companies in the financial services industry.

The purpose of this paper is to investigate the impact of the global coronavirus (COVID-19) pandemic on stock market liquidity, while taking into account the depth and tightness dimensions.

The author used a panel data regression on stock market dataset, representing 314 listed firms operating in six Middle East and North African (MENA) countries from February to May 2020.

The regression results on the overall sample indicate that the liquidity related to the depth measure was positively correlated with the growth in the confirmed number of cases and deaths and stringency index. Moreover, the market depth was positively related to the confirmed cases of COVID-19. The results also indicate that the liquidity of small cap and big cap firms was significantly impacted by the confirmed number of cases, while the stringency index is only significant for the liquidity depth measure. Moreover, the results regarding sectors and country level analysis confirmed that COVID-19 had a significant and negative impact of stock market liquidity.

This paper confirms that the global coronavirus pandemic has decreased the stock market liquidity in terms of both the depth and the tightness dimensions.

While most empirical papers focused on the impact of the COVID-19 global pandemic on stock market returns, this paper investigated liquidity chock at firm level in the MENA region using both tightness and depth dimensions.

Reconstruction of old buildings is often necessary after prolonged usage, but these projects encounter various complexities, leading to their failure. However, there is a lack of studies that focus on investigating the complexity of old building reconstruction initiatives. Thus, this study aims to examine the complexity of reconstruction projects for old buildings in Vietnamese urban areas.

Through a literature review and discussions with experienced practitioners, 12 significant complexity factors were identified. The study then utilized the fuzzy decision-making trial and evaluation laboratory (DEMATEL) technique to analyze the interrelationships among these complexity factors.

The findings revealed intricate interdependencies among the complexity factors, visualized in a complexity map. The map highlighted the critical complexities of site compensation, clearance and the long project duration. Furthermore, a causal diagram categorized the complexity factors into net-effect and net-cause groups.

By examining the relationships and interactions among these factors, the study emphasizes the interconnected nature of complex systems and the influence of one factor on others. Therefore, decision-makers and stakeholders involved in reconstructing old buildings are suggested to possess a comprehensive understanding of these interdependencies to ensure effective decision-making.

This paper aims to measure the COVID-19-related disclosure extent of listed firms in Vietnam and its associated factors.

The authors apply a previously developed reporting framework to evaluate the disclosures of 100 listed firms with the largest market capitalization on the Hanoi and Ho Chi Minh stock exchanges as of 31 December 2021. The disclosures were from integrated reports, annual reports, corporate governance reports and financial statements. The authors then used a regression model to examine the factors that influenced the disclosures, such as corporate governance, ownership concentration and firm profiles.

The research results reveal that the extent of COVID-19-related disclosure in Vietnam is relatively low. It also finds that the audit committee, firm size, age and industry are positively associated with the extent of COVID-19-related disclosure.

To the best of the authors’ knowledge, this study is the first to examine COVID-19-related disclosures of listed companies in Vietnam and their determinants. It contributes significantly to the empirical evidence in this field. The findings of this study can help corporate managers and policymakers to improve information disclosure practices during future financial crises.

This study aims to investigate whether the extent of corporate disclosure, proxied by COVID-19-related disclosure, affects the dividend policy of listed firms.

The study uses a multinomial logistic regression model to examine the relation between corporate disclosure and the dividend policy of the 100 largest market-cap firms in Vietnam in 2021. The COVID-19 pandemic, with its unique impact on business operations, serves as the backdrop for this analysis.

The findings indicate that firms with more extensive COVID-19-related disclosure are more inclined to distribute dividends in the form of stocks or cash instead of omitting them.

This research contributes to the understanding of how corporate disclosure practices influence a firm’s financial decisions, particularly in the context of the COVID-19 pandemic. The findings hold implications for corporate financial decision-making during times of macroeconomic shock.

This paper aims to explore how research and development (R&D) scientists and engineers can contribute to sustainability initiatives in their organisations.

This paper uses a critical case study methodology, focussed on a large Vietnamese company in which business leaders sought to engage R&D scientists and engineers in sustainability initiatives focussed on eco-innovation and eco-efficiency. Bourdieu’s theoretical lens of habitus, capitals and field facilitates a relational analysis of the findings.

While R&D scientists and engineers adapted well to early changes aligned with eco-innovation, they struggled to engage with sustainability initiatives in the case firm. This study explains adaptions and constraints as scientists and engineers’ professional habitus and capitals, and their broader organisational field.

This paper provides insight into how organisations might integrate professional acculturation and appropriate facilitators to promote the additional contribution of scientists and engineers to sustainability initiatives in the context of an organisation.

Although eco-innovation and eco-efficiency are only potential dimensions of comprehensive organisational sustainability reform, this research provides insight into how engaging scientists and engineers with a broader social sustainability agenda might be advanced.

The study addresses calls for empirical insights into ways that scientists and engineers can commit to organisational sustainability practices based on the configurations of habitus, capital and organisational field.

The purpose of this study is to examine the influence of board characteristics on environmental performance in manufacturing firms of the emerging East Asian markets. The authors adopt a triple perspective of environmental performance that focusses on three major environmental areas including resource reduction, emission reduction and product innovation.

The authors consider three main board characteristics, namely, board size, board independence and board leadership structure, and investigate their impacts on a multidimensional construct of environmental performance. Specifically, both linear and quadratic functions are applied to address a possibility of the non-linear relationship between board size and environmental performance. The authors use fixed-effects estimations on a sample of manufacturing firms in the emerging East Asian countries between 2011 and 2016.

The study explores an inverse U-shaped relationship between board size and environmental performance. The authors also reveal that manufacturing firms are more likely to have better environmental performance when the proportion of independent directors on board increases. However, the separation of CEO and board chair roles has no impact on environmental performance.

The findings have important implications by identifying the role of a board of directors in implementing environmental protection strategies and by providing a foundation for corporate efforts to enhance sustainable development.

The study provides complete understanding of environmental performance as a multidimensional construct and sheds light on the influence of board characteristics, especially the inverse U-shaped influence of board size, on environmental performance in the East Asian manufacturing industries.

This paper aims to examine the levels of integrated reporting disclosure alignment in annual reports by listed firms in Vietnam and the factors influencing these disclosure levels.

Drawing on a sample of 200 listed firms in Vietnam in 2017, the authors constructed a disclosure index based on the content of the International Integrated Reporting Committee (IIRC) Framework. Using this index, the study measures the extent to which Vietnamese listed firms’ annual reports include the content elements required by the integrated reporting (IR) Framework. The study performs ordinary least square regression to investigate the influencing factors.

The study documents that, on average, Vietnamese listed firms disclose about 43% of the information required by the IIRC Framework. The disclosure levels are positively associated with manufacturing firms, board independence, foreign ownership, government ownership, audit quality and firm size.

Integrated reports have been widely adopted in many countries, but it is still a new issue in Vietnam. This is the first paper providing some insights into the inclusion of the content elements required by the IR Framework by listed firms in Vietnam. It also contributes to the disclosure literature by providing empirical evidence on the factors influencing these disclosure levels. Deriving from the findings, the authors offer recommendations for policymakers on the issue of regulating and implementing IR in Vietnam.

Concrete gravity dams are important structures for flood control and hydraulic power generation, but they can be vulnerable to seismic activity due to ground movements that trigger crack propagation.

To better understand the factors that affect the stability of concrete gravity dams against concrete fracture during earthquakes, a concrete plastic damage model has been utilized with two new expressions to simulate compressive and tensile damage variables.

The findings showed that the crack patterns were strongly influenced by the concrete’s strength. The simulation results led to the proposal of appropriate concrete properties aimed at minimizing damage. These findings, together with the proposed model, offer significant insights that can enhance the safety and stability of concrete gravity dam structures.

This study offers a comprehensive analysis of concrete behavior under varying grades and introduces simple and robust expressions for evaluating concrete parameters in plastic damage models. The versatility of these expressions enables accurate simulation of stress-strain curves for different grades, resulting in excellent agreement between model results and experimental findings. The simulation of the Koyna Dam case study demonstrates a similarity in crack patterns with previous simulations and field observations.

This study aims to reveal the impact mechanism of franchisor-owned resources, franchise relationship quality and franchisee's dynamic capabilities on franchisee performance, with the moderating role of cultural sensitivity.

The sample consisted of 290 middle managers and team leaders at 113 hotels and food and beverage settings participating in the international- and domestic franchises in Ho Chi Minh City, Vietnam. A partial least squares structural equation model (PLS-SEM) is used to analyse the data.

The result reveals that franchisor-owned resources, franchise relationship quality and franchisee's dynamic capabilities significantly impacted franchisee performance. Furthermore, cultural sensitivity has a beneficial role in the effect of franchise relationship quality on franchisee performance.

This study develops an integrated analytical framework of franchisee performance from the franchisee's perspective, contributing to integrating international business theory in franchising studies, namely the resource-based view, dynamic capability view and relationship-marketing theory.
