Abstract

Purpose

This paper aims to present an optimization algorithm combined with the impedance control strategy to optimize the robotic dual peg-in-hole assembly task, and to reduce the assembly time and smooth the contact forces during assembly process with a small number of experiments.

Design/methodology/approach

Support vector regression is used to predict the fitness of genes in evolutionary algorithm, which can reduce the number of real-world experiments. The control parameters of the impedance control strategy are defined as genes, and the assembly time is defined as the fitness of genes to evaluate the performance of the selected parameters.

Findings

The learning-based evolutionary algorithm is proposed to optimize the dual peg-in-hole assembly process only requiring little prior knowledge instead of modeling for the complex contact states. A virtual simulation and real-world experiments are implemented to demonstrate the effectiveness of the proposed algorithm.

Practical implications

The proposed algorithm is quite useful for the real-world industrial applications, especially the scenarios only allowing a small number of trials.

Originality/value

The paper provides a new solution for applying optimization techniques in real-world tasks. The learning component can solve the data efficiency of the model-free optimization algorithms.

Abstract

Purpose

This study aims to reduce the warping deformation of the stainless composite plate after removal strake by using a finite element method. A three-dimensional thermo-mechanical coupled elastic-plastic finite element model has been suggested by using ABAQUS to simulate the multi-pass hot rolling of stainless composite plate.

Design/methodology/approach

A three-dimensional thermo-mechanical coupled elastic-plastic finite element model has been suggested by using ABAQUS to simulate the multi-pass hot rolling of stainless composite plate. Warping deformation rules of 316L/Q345R stainless composite plate after removal strake have been analyzed. Moreover, the influences of some different rolling parameters on this deformation have been discussed.

Findings

The warping deformation just varies in the range of cladding ratio from 0.1 to 0.25. Therefore, cladding ratio does not have a great influence on warping deformation.

Originality/value

The results show that higher heating temperature, larger final thickness and less rolling passes are beneficial for reducing the warping deformation.

Abstract

Purpose of this paper – This study investigates compliance with the corporate governance code in an African developing economy (Mauritius).

Methodology/approach – We examine the annual reports of 41 listed companies to assess the extent of compliance with the code and to analyze the wording of compliance statements. We also carry out in-depth semi-structured interviews with selected company directors to understand the reasons for compliance (or non-compliance).

Findings – Initial findings indicate a reasonable level of compliance with the more visible requirements of the code but noteworthy non-compliance also emerges, particularly in relation to the low number of company boards being chaired by independent directors, to uncertainties on the actual operation of board committees, and to the widespread non-disclosure of directors’ remuneration. Furthermore, compliance statements were found to be vague, ambiguous, or even inconsistent with the extent of compliance disclosed in the reports. We believe these are indications that many of the companies are adhering selectively with the code to project an image of symbolic compliance. Our in-depth follow-up interviews with directors largely confirm this behaviour of selective compliance.

Research implications – We suggest that the pursuit of legitimacy as an operational resource – rather than efficiency-led rationales – emerges as a potential theoretical explanation for the adoption of the corporate governance code in Mauritius.

Originality /value of paper – We bring evidence on how the corporate governance code is being understood and rationalized in a developing economy. We rely on a combination of annual report disclosures, compliance statements, and interview data to investigate corporate governance compliance.

Abstract

Purpose

The purpose of this study is to ascertain the control role of independent non-executive directors (INEDs) in Malaysian public listed companies (PLCs), as prescribed in the Malaysian Code on Corporate Governance (MCCG).The MCCG (2000) requires substantive involvement of INEDs on the audit, nomination and remuneration board sub-committees. The study also examines the effectiveness of INEDs in discharging their monitoring roles in these sub-committees.

Design/methodology/approach

A qualitative research design consisting of a series of interviews with board members of Malaysian-owned PLCs on the board of Bursa Malaysia was used.

Findings

Interviews with 27 company directors reveal that, due to their independence, INEDs are crucial in safeguarding the interests of smaller investors if situations arise in which shareholders’ interests may be threatened. The interviews also disclose that the audit committee possesses the most authority among the sub-committees, as it derives its power not only from the Listing Requirements but also from statute, as well as being involved in areas of the company not traditionally associated with the committee. The study also reveals the differences in opinion between executive directors and INEDs with regard to the extent of INEDs’ effectiveness.

Research limitations/implications

This research utilises interviews. Generalisation may be an issue when interviews are used as the method of inquiry. In addition, the sample is not random, as access to many directors is dependent on recommendations. In addition, the respondents have been consciously selected to cover various board positions, including independent and non-independent directors.

Practical implications

The findings from this research suggest that INEDs are able to discharge their responsibilities in overseeing the conduct of executives and protecting the interests of investors. In addition, the interviews disclose that the effectiveness of INEDs depends on how non-executive directors view INEDs being on the board. Rather than focusing solely on their control role, INEDS are expected to have a more proactive and progressive role in ensuring sustainable growth and the expansion of the business entity.

Originality/value

There are limited studies using qualitative research design in investigating the effectiveness of INEDs in the control role of the board in developing countries. Prior studies were predominantly based upon the experience of Western economies.

Abstract

Purpose

The purpose of this paper is to present a mini review of corporate governance in Malaysia. The paper acts as an introduction to the history of corporate governance in Malaysia, from the starting point until the release of the new Blue Print.

Design/methodology/approach

The paper adopts a browsing method that takes into consideration the review of the Malaysian Code of Corporate Governance. It also reviews the new blue print of the code of governance in Malaysia.

Findings

An extensive effort is being implemented to improve the corporate governance mechanisms in Malaysia and although Malaysia is following the UK style in designing the corporate governance code, it secured the 4th position among the world's top countries growing in the direction of attracting investors.

Originality/value

This is a review paper based on the guidelines of corporate governance in Malaysia.

Abstract

Purpose

The purpose of this paper is to examine the influence of the characteristics of audit committee chairman (ACC) (tenure, age, gender, ethnicity, accounting expertise and directorship) on earnings management (EM) practices.

Design/methodology/approach

The Jones model and modified Jones model by Dechow et al. (1995) were used to determine the discretionary accruals (DA) of 288 Malaysian listed firms with lowest positive earnings for the years 2013‒2015.

Findings

The results of the ordinary least squares regression indicate that only tenure, gender and ethnicity of the ACC are associated with DA. A further test was conducted by dividing firms into two groups: firms whose boards are chaired by a family member and firms whose boards are chaired by a non-family member. The results reveal that it is possible for firms whose boards are chaired by family members to cause the corporate governance (CG) mechanisms, particularly the audit committee, to lose their effectiveness in overcoming the EM problem. In addition, robustness tests were conducted by using panel data regression, where the results were found to be similar to the original regression results.

Originality/value

This study alerts policymakers, firms and their stakeholders, as well as researchers, regarding the importance of having an independent board chairman, who has no relationship with any directors or major shareholders, as this may hinder the effectiveness of CG mechanisms in curbing EM, especially in emerging countries, such as Malaysia, where it is very difficult to stop members of the family from becoming board directors.

Abstract

Purpose of paper – Rural Banks (RBs) are unit banks owned by members of the rural community through the purchase of shares and are licensed to provide financial intermediation in rural areas of Ghana. This paper reports on the external and internal mechanisms through which corporate governance is maintained in these banks.

Design/methodology/approach – The findings reported in the paper are based on evidence obtained from a review of relevant documents and interviews with the managers of selected RBs.

Findings – The corporate governance system in the RBs is mainly a rational western model recommended by the World Bank and implemented by the Central bank of Ghana. Under this model corporate governance is expected to be maintained externally through regulatory agencies (the Central Bank of Ghana and the Association of Rural Banks) and internally through the respective Boards of Directors. However, we observe that because of the locations and ownerships of these banks, board appointments and decisions are often embedded in local political and social relations. This affects the independence of the boards and impacts on their role in maintaining corporate governance.

Research limitations/implications – We argue that any attempt to design corporate governance systems in these banks without taking these social and political factors into consideration is likely to lead to failure. This is particularly important given that the World Bank and other international donors are continuously proposing rational western models of governance to institutions in the developing world, such as the RBs. Given that these organizations operate under different sets of environmental conditions, there is likely to be differences between the actual and the idealized corporate governance systems.

Originality/value of paper – The study is important because of the role the rural banks play in the socio-economic development of Ghana. Several other developing countries have established similar institutions to support the development of the informal sector through the provision of microcredit. The research will contribute to the design of appropriate corporate governance systems so as to improve the overall contributions of these institutions.

Abstract

Purpose – The objective of this paper is to examine how state-owned entities (SOEs) engage with the requirements of the corporate governance code in an African developing economy (Mauritius).

Approach – A content analysis of the annual reports of SOEs and National Audit Office (NAO) reports is undertaken. This is supplemented by semi-structured interviews with relevant directors and regulatory bodies.

Findings – We report a substantial non-implementation of the code and identify several impediments to the transposing of the corporate governance model to the state-owned entities. The salient issues relate to the inadequate definition of SOEs in the code, the different conceptualisations of ownership and accountability, the influence of political rivalries and the low level of financial accountability in SOEs. We also consider our findings in relation to the theoretical perspectives of ‘efficiency gains’ and ‘social legitimation’.

Originality/value – Very few studies have looked into the applicability of codes of corporate governance in SOEs. In spite of the prominence of SOEs in many African developing countries, empirical evidence on corporate governance implementation in such entities has been scant.

Recommendations/implications – The findings are of relevance to policy-makers and regulators who seek to rely on mainstream corporate governance principles and practices to enhance the accountability and transparency of SOEs. Key enabling conditions for corporate governance implementation involve a depoliticisation of board appointments and a redefinition of the accountability relationships between SOEs and their ultimate owner (i.e. elected representatives and taxpayers).

Abstract

Purpose

The purpose of this paper is to investigate the effect of managerial ownership in relation to agency theory in the Malaysian business environment. In addition to examining the total managerial shareholdings, this study also investigates the association between direct and indirect managerial shareholdings with agency costs.

Design/methodology/approach

The data for the study is obtained from two sources, namely primary (questionnaire) and secondary (annual reports) data. The sample companies are 235 companies listed on Bursa Malaysia for the financial year ended 2006. Multiple regression analysis is used to estimate the relationship between the variables.

Findings

The results of the study indicate that managerial ownership in various segments has an inverse relationship with total monitoring costs as predicted in agency theory. This finding is consistent with earlier studies in western countries and supports the convergence of interest hypothesis.

Originality/value

This study gives a unique contribution to corporate governance studies relating to the effect of ownership structure in relation to agency theory in Malaysian companies, one of the countries in Asia. Previous studies claimed that it is unknown whether the agency theory findings in western countries have equal impact in Asian organizations. Previous literature also indicates that there is a possibility that given the cultural differences, the typical nature of agents in agency theory may not be the case with regard to non‐western countries. Thus, this study provides evidence that support prior research findings in western countries relating to the effect of managerial ownership on the agency relationship which is reflected in its agency costs.
