This paper aims to provide a critical discussion of the application of the research pitching template developed by Professor Robert Faff to a research topic of tax avoidance and firm risk. This letter provides a brief commentary on using the pitching template and discusses personal reflections on the pitching process.

This pitching research letter applies Faff’s pitching template and provides a critical commentary of the pitching process.

The team found that Faff’s pitching template is a valuable tool for conceiving research ideas. It helped the authors to identify, develop and articulate key aspects of the project. Further, they believe that completing the template was a beneficial and rewarding exercise, especially for early-career researchers.

This pitching research letter is tied to the team’s research idea that was pitched at the 2020 AFAANZ “Shark Tank” event. It provides original commentary on the use of Faff’s pitching template. It is not meant to retrofit published papers.

The purpose of this paper is to investigate the impact of independent directors on firm performance in Vietnam and identify how different types of ownership structure and the presence of controlling shareholders influence the relationship.

For a sample of 217 non-financial Vietnam-listed companies during the period from 2010 to 2014, this study uses the ordinary least squares regressions to estimate the relationship between independent directors and firm performance. Two econometric techniques – the fixed effects estimation and the difference in difference estimation – are used to control for endogeneity. The results are also robust to the lag variable of independent directors.

The results reveal that independent directors have an overall negative effect on firm operating performance. This finding may be because of information asymmetry, expertise disadvantage and the dominance of ownership concentration that prevent independent directors from fulfilling their monitoring function in governance. The negative relationship between independent directors and firm performance is stronger in firms where the State is a controlling shareholder.

Findings suggest that changes relating to independent directors, as a response to the new corporate governance code in 2012, do not have a positive effect on the relationship between corporate governance and firm performance. Further reform is required to improve internal control mechanisms and corporate governance systems in Vietnam.

This is the first study to provide a robust evidence on the relationship between independent directors and firm performance in Vietnam as well as to explore the impact of the type of controlling shareholders on the relationship.

The purpose of this paper is to examine the perceptions of independent directors in Vietnam about their roles and challenges when sitting on the boards of listed companies.

The study uses mailed questionnaires to collect data. The authors sent surveys to 810 independent directors from 354 listed companies and received feedback from 170 respondents.

The authors examine several aspects of independent directors’ work on the board (such as the roles of and challenges for independent directors) as well as board environment (such as information provision or board interaction). Findings suggest that independent directors in Vietnam place more emphasis on their advisory role than their monitoring role. In addition, they also point out their challenges including information asymmetries and the influence of controlling shareholders. These challenges are significant and they prevent independent directors to properly execute their independent role on the board. These findings reflect the unique features of corporate governance in transition economies.

The authors contribute to the literature through providing an insightful view about the nature of the work performed by this type of director in a transition economy. The study is also one of the first studies to use a qualitative instrument to provide an explanation of how controlling shareholders influence independent directors on boards of directors.

This study conducts an empirical examination of auditors’ interpretation of selected key uncertainty expressions, namely virtually certain, probable and unlikely, included in accounting standards.

This paper adopts a survey research method to examine the impact of gender difference on the interpretation of uncertainty expressions. Professional auditors in China were selected to examine whether gender difference influences the interpretation of uncertainty expressions.

The results show that female auditors are likely to interpret positive or negative uncertainty expressions more conservatively than male auditors. The extent of conservatism is higher when female auditors are interpreting in-context expressions. The results remain similar after controlling for additional variables, such as education and work experience, which possibly affect the interpretation of probability expressions.

The results of this study suggest that gender difference can affect the numerical thresholds that auditors’ assign to uncertainty expressions. This may lead to different application of professional judgments between male and female auditors. It also provides important implications to regulators and practitioners on the quality of financial reporting and auditing across organizations within and across countries.

In this paper, a nine-dimensional chaotic system is designed and applied to secure communication.

Firstly, the equilibrium characteristics, dissipativity, bifurcation diagram and Lyapunov exponent spectrum are used to analyze the relevant characteristics of the proposed nine-dimensional chaotic system. In the analysis of Lyapunov exponential spectrum, when changing the linear parameters, the system shows two states, hyperchaos and chaos. For secure communication, there is a large secret key space. Secondly, C0 complexity and SEcomplexity of the system are analyzed, which shows that the system has sequences closer to random sequences.

The proposed nine-dimensional system has a large key space and more complex dynamic characteristics

The results show that the proposed nine-dimensional hyperchaotic system has excellent encryption capabilities and can play an important role in the field of secure communication.

Japan's decision to release nuclear wastewater into the Pacific Ocean in 2023 has sparked strong opposition at home and abroad. In this study, Graph Model for Conflict Resolution (GMCR) method is adopted to analyze the conflict problem, and reasonable equilibrium solutions are given to solve the conflict event.

In this study, GMCR is adopted to solve the conflict problem. First, identify the key decision-makers (DMs) on the issue of nuclear effluent and the relevant options they might adopt. Second, the options of each DM are arranged and combined to form a set of feasible states. Thirdly, the graph model is constructed according to the change of DM's options, and the relative preference of each DM is determined. Finally, the conflict problem is solved according to the definition of GMCR equilibrium.

Discharging nuclear wastewater into the ocean is not the right choice to solve the problem. Developing more space to store nuclear wastewater is more conducive to the protection of the ocean environment.

It is undesirable for the Japanese government to unilaterally discharge nuclear wastewater into the ocean. Objectively assessing the radioactivity of nuclear wastewater and the cooperation of relevant stakeholders can better solve this conflict.

The problem arising from Japan's releasing plan is complicated because of a lack of information and the existence of multiple stakeholders, while GMCR can help us with a better view of the current circumstance in the conflict.

With the development of integrated circuit and communication technology, digital secure communication has become a research hotspot. This paper aims to design a five-dimensional fractional-order chaotic secure communication circuit with sliding mode synchronous based on microcontroller (MCU).

First, a five-dimensional fractional-order chaotic system for encryption is constructed. The approximate numerical solution of fractional-order chaotic system is calculated by Adomian decomposition method, and the phase diagram is obtained. Then, combined with the complexity and 0–1 test algorithm, the parameters of fractional-order chaotic system for encryption are selected. In addition, a sliding mode controller based on the new reaching law is constructed, and its stability is proved. The chaotic system can be synchronized in a short time by using sliding mode control synchronization.

The electronic circuit is implemented to verify the feasibility and effectiveness of the designed scheme.

It is feasible to realize fractional-order chaotic secure communication using MCU, and further reducing the synchronization error is the focus of future work.
