The purpose of this paper is to investigate the impact of independent directors and ownership structure on voluntary disclosures of Vietnamese listed firms.

Year‐ending 2008 annual report disclosures of 45 Vietnamese listed firms are analyzed. Voluntary disclosure is measured using a Vietnamese Disclosure Index adapted from prior literature. Descriptive and inferential statistics (T‐test, analysis of variance, multiple regressions (ordinary least squares)) are employed to generate empirical insights.

The results indicate that the level of voluntary disclosure among Vietnamese listed firms is relatively low (24.23 per cent). There are higher levels of disclosure relating to director and senior management details but far lower in regards to social issues. State ownership and managerial ownership are negatively and positively related to the extent of voluntary disclosure respectively. Moreover, bigger firms are found to be positively associated with voluntary disclosure.

The results of this study are limited to one year – 2008 – and thus, could be biased as disclosures can change over time.

Vietnamese regulators should focus on strengthening the regulations governing the level of corporate communication in firms with high state ownership as well as encouraging more disclosure of non‐financial information to strengthen its market information transparency.

This study is one of the first examining the level of corporate voluntary disclosure practices among Vietnamese listed firms. Evidence from this study extends the existing voluntary disclosure literature on emerging economies whilst providing valuable insights to Vietnamese policy makers in the process of developing and improving its financial reporting regulatory framework.

This paper aims to use the Monodepth method to improve the prediction speed of identifying the obstacles and proposes a Probability Dueling DQN algorithm to optimize the path of the agent, which can reach the destination more quickly than the Dueling DQN algorithm. Then the path planning algorithm based on Probability Dueling DQN is combined with FastSLAM to accomplish the autonomous navigation and map the environment.

This paper proposes an active simultaneous localization and mapping (SLAM) framework for autonomous navigation under an indoor environment with static and dynamic obstacles. It integrates a path planning algorithm with visual SLAM to decrease navigation uncertainty and build an environment map.

The result shows that the proposed method offers good performance over existing Dueling DQN for navigation uncertainty under the indoor environment with different numbers and shapes of the static and dynamic obstacles in the real world field.

This paper proposes a novel active SLAM framework composed of Probability Dueling DQN that is the improved path planning algorithm based on Dueling DQN and FastSLAM. This framework is used with the Monodepth depth image prediction method with faster prediction speed to realize autonomous navigation in the indoor environment with different numbers and shapes of the static and dynamic obstacles.

This paper aims to report on the experiments with the Contour Crafting Automated Construction process using sulfur concrete as the choice of construction material.

Several experiments have been performed at centimeter and meter scales. A finite element analysis simulation model for the behavior of sulfur concrete-based structures has been developed. Experimental results were compared with the results of simulation.

Sulfur concrete has numerous terrestrial applications and is potentially an ideal construction material for planetary construction.

Experimental samples of sulfur concrete were fabricated using a novel mixer/extrusion system. The mechanism was proven to be durable and stable after more than 500 h of work.

The purpose of this paper is to investigate the association between corporate governance mechanisms and quality of forward-looking information in the Chinese stock market which presents a mandatory disclosure environment for forward-looking information.

Using sales forecasts to proxy forward-looking information and using precision and accuracy to measure the quality of information disclosure, the authors investigate the impact of corporate governance attributes on the precision and accuracy of sales forecasts made by listed Chinese firms in their 2010 annual reports, using logistics and ordinary least squares regressions.

The authors find good corporate governance has a positive and significant impact on the precision choice of sales forecasts disclosure. Firms with good corporate governance are more likely to disclose more precise sales forecasts than providing qualitative discussions on firms’ sales trend. In addition, good corporate governed firms are found more likely to provide precise non-financial information. The authors also find that good corporate governance is positively associated with making more conservative sales forecasts disclosure. However, the authors find no significant relationship between good corporate governance and smaller forecast error.

The study makes significant contributions to corporate disclosure literature. The authors investigate the determinants of the quality of forward-looking information in a mandatory disclosure regime while most forward-looking information disclosure literature have been conducted in a voluntary-based disclosure environment. The authors examine whether in a mandatory disclosure regime, corporate governance mechanisms can play a positive role in precision choices and accuracy of forward-looking information. Further, the study is the first to examine corporate governance and the quality of non-financial forward-looking information (sales target and production goal). The research findings therefore extend forward-looking information disclosure research from financial information to non-financial information.

The empirical findings will provide regulators with evidence on the quality of forward-looking information in a mandatory disclosure regime and the influence of corporate governance on forward-looking disclosure. The properties of forward-looking information disclosure in China should be of interest to policy makers, investors and financial analysts in other international jurisdictions.

The study investigates forward-looking information in a mandatory disclosure regime while most extant forward-looking information studies have been conducted in a voluntary disclosure environment. The study is the first to examine the quality of non-financial forward-looking information such as operational goals and plans, and to investigate the association between the quality of non-financial forward-looking information and corporate governance mechanisms. The research findings extend forward-looking information disclosure research from quantitative financial information to quantitative non-financial information.

The aim of this paper is to investigate stakeholder power changes and their impact on firms' disclosure decisions in the Chinese stock market. Using legitimacy theory and stakeholder theory, the paper identifies newly emerged stakeholder groups for listed Chinese firms during three distinguished periods of the development of the Chinese stock market.

Panel data analysis was undertaken over a period from 1995‐2006 with an aim to examine the influence of stakeholder power changes on voluntary disclosures made by 297 listed firms in their 12 years of annual reports. A voluntary disclosure checklist has been used for hand‐collecting data from annual reports.

The finding shows that different stakeholder groups exert different degrees of influence on firms' decision‐making in respect of information disclosure during different stages of the development of the Chinese stock market.

The impact of a stakeholder power changes on corporate disclosure has not been well addressed and how listed Chinese firms respond to these changes is still a significant gap in the Chinese corporate disclosure literature. In this study, the paper uses proxies to represent each stakeholder group, discuss power changes of each group and predict the impact of power changes on firms' voluntary disclosure.

The paper identifies the new content of the “social contract” between listed firms and Chinese society and identifies various stakeholder groups of listed Chinese firms in the context of a new “social contract”. The paper predicts that voluntary corporate disclosure is the result of stakeholder pressures and firms use voluntary disclosure as one of their strategies to manage the firm‐stakeholder relationship.

A direct and unified approach is proposed toward simultaneously simulating large strain elastic behaviors of gellan gels with different gellan polymer concentrations. The purpose of this paper is to construct an elastic potential with certain parameters of direct physical meanings, based on well-designed invariants of Hencky’s logarithmic strain.

For each given value of the concentration, the values of the parameters incorporated may be determined in the sense of achieving accurate agreement with large strain uniaxial extension and compression data. By means of a new interpolating technique, each parameter as a function of the concentration is then obtained from a given set of parameter values for certain concentration values.

Then, the effects of gellan polymer concentrations on large strain elastic behaviors of gellan gels are studied in demonstrating how each parameter relies on the concentration. Plane-strain (simple shear) responses are also presented for gellan gels with different polymer concentrations.

A direct, unified approach was proposed toward achieving a simultaneous simulation of large elastic strain behaviors of gellan gels for different gellan polymer concentrations. Each parameter incorporated in the proposed elastic potential will be derived as a function of the polymer concentration in an explicit form, in the very sense of simultaneously simulating large strain data for different concentrations.

Drawing from Upper-Echelons Theory (UET), this paper aims to examine whether an increasing number of board members studying and working overseas, especially in Anglo countries, provides some impetus for increased corporate environmental disclosures (CED) in Vietnam.

This study used quantitative data collection and analysis. The data collection involved a content analysis of annual, sustainability and integrated reports to capture the quality and quantity of CED. The authors subsequently developed ordered probit models to quantitatively test the hypotheses.

The authors find that board members studying in Anglo countries positively impact firms’ levels of CED in emerging economies. However, overseas work experience is found to be an insignificant explanatory variable. Further, the findings suggest that, in Vietnam, Chairs appear to be more influential than chief executive officers in affecting CED levels.

Despite the positive influence of overseas study, the authors find overall levels of CED in Vietnam remain relatively low. This suggests the necessity of dialogue about potential reform in CED policies, which could involve the introduction of mandatory reporting requirements. In addition, to enhance sustainability disclosures, shareholders should appoint board members who possess international qualifications.

This study adds to the literature exploring the impacts of Anglo cultural traits of board members on CED levels, within an economy transitioning from a communist ideology to a market-oriented system context. The connection between international study and cultural norms, beliefs and traditions in these countries and their positive influence on directors’ values and attitudes towards CED have not yet been studied. The study also extends UET by examining the potential positive influence of different national contexts on board members’ education levels.

To examine China's reforms and successes could have been replicated to other transition economies.

The applicability of the Chinese process as an alternative for transition economies involves an analysis of the necessary reforms regarding price liberalisation‐stabilisation; privatisation; institutions; monetary policy and the financial system; fiscal policy; international trade and foreign aid and social policy.

The transition process in China has maintained political‐ideological authoritarianism and state control of the whole economy. Therefore, it was not the “special initial conditions” of China that made the model inappropriate but, rather, the switch to a democratic political‐ideological‐economic structure in transition economies.

The paper contributes to the transition literature by demonstrating that the strategy was only rendered workable in China, as the governments of transition economies neither had the mandate nor wanted to reimpose tight state direction of the politics, ideology and economy.

The information used for supervision by regulatory departments in public-private partnership (PPP) projects is primarily transmitted and processed by the PPP implementation department, which negatively impacts the information quality, leading to information asymmetry and undermining the overall effectiveness of supervision. This study aims to explore how to use blockchain to anchor the information used for supervision in PPP projects to the original information, to strengthen the oversight.

This paper adopts the principles of design science research (DSR) to design a conceptual framework that systematically organizes information along the information dissemination chain, ensuring the reliable anchoring of original information. Two-stage interviews involving experts from academia and industry are conducted, serving as formative and summative evaluations to guide the design.

The framework establishes a weak-centralized information organizing mode, including the design of governance community and on-chain and off-chain governance mechanisms. Feedback from experts is collected via interviews and the designed framework is thought to improve information used for supervision. Constructive suggestions are also collected and analyzed for further development.

This paper provides a novel example exploring the inspirations blockchain can bring to project governance, like exercising caution regarding the disorderly expansion of public sector authority in addressing information disadvantages and how to leverage blockchain to achieve this. Technical details conveyed by the framework deepen understanding of how blockchain benefits and the challenges faced in successful implementation for practitioners and policymakers. The targeted evaluation serves as rigorous validation, guiding experts to provide reliable feedback and richer insights by offering them a more cognitively convenient scenario.
