Abstract

Purpose

The purpose of this paper is to examine the role of internal audit with respect to Auditing Corporate Governance Statements based on a practical approach. Moreover, it examines the application of internal control best practices in the Athens publicly listed firms based on a series of related statements.

Design/methodology/approach

The authors conducted all large and medium capitalization publicly listed companies via a research questionnaire which forms a basis of a descriptive research analysis. The methodology is based on the best worldwide acceptable practices as represented by the Committee of Sponsoring Organizations internal control – integrated framework, as well as the relevant laws and regulations and best practices with respect to Corporate Governance Statements.

Findings

The research concludes that internal auditors limit their role in verifying compliance with the relevant laws and regulations rather than adopt a consulting role toward the improvement of the content and quality of Corporate Governance Statements information. Also, it contributes to the corporate governance research by verifying that the effectiveness of internal controls contributes to sound corporate governance practices.

Practical implications

Internal auditors depending on the organization they serve may adopt different roles regarding Corporate Governance Statements preparation, review and audit such as consultative which may add value to the quality of Corporate Governance Statements.

Originality/value

It is the first research regarding quality characteristics of the Corporate Governance Statements and the role of internal audit in Greece, and it provides the basis for further research among European Union countries.

Abstract

Purpose

The purpose of this study is to review the literature on corporate governance (CG); environmental, social and governance (ESG) issues and corporate social responsibility (CSR) during the Coronavirus disease 2019 (COVID-19) pandemic and addresses three research questions: What are the characteristics of the literature on CG and COVID-19? What are the themes in CG in the COVID-19 era? and What are key areas of future research on CG and COVID-19?

Design/methodology/approach

The authors attempted a systematic literature review of 62 studies published in 2020. The authors used four criteria to identify characteristics of the literature on CG and COVID-19 and three criteria to identify key themes in the literature addressing CG and the pandemic. The authors analyzed answers to the above research questions and proposals from studies reviewed to guide future research.

Findings

CG in the context of COVID-19 has been studied mostly in developed countries and within a theoretical framework. As accounting data are insufficient, more research is required in all countries (developed, emerging and other). Further, there are no conclusive results regarding the relevance of ESG and CSR to financial performance. Future research should use additional methodologies and data sources to fully explain the impact of COVID-19 on CG.

Practical implications

Practitioners and policymakers could benefit from the study, as the authors present key challenges to CG for the present and the future.

Originality/value

This study is the first to provide a systematic literature review on CG during the COVID-19 pandemic and presents current trends, challenges and avenues for future research.

The purpose of this study is to investigate risk disclosure in listed Greek companies. The effects of the financial crisis were also considered.

Abstract

Purpose

The purpose of this study is to investigate risk disclosure in listed Greek companies. The effects of the financial crisis were also considered.

Design/methodology/approach

This study aimed to determine the risk-reporting practices of Greek’s non-financial companies listed on the Athens Stock Exchange through a content analysis of their annual reports.

Findings

Risk identification and anticipation protect businesses and create shareholder value. In recent years, particularly since the economic crisis, risk has become one of the most important business issues. This study concluded that during the crisis, there was an increase in disclosure. Financial, personnel and legal risks were the most reported types of risk. This study also found liquidity to be a very important issue.

Research limitations/implications

Content analysis has limitations because subjectivity cannot be eliminated. This study measured only the quantity, not the quality, of risk disclosure. The quality of risk reporting will be examined in future research.

Originality/value

This is the first study on risk disclosure in the non-financial companies listed on the Athens Stock Exchange to conduct a content analysis of the corporate annual reports.

This paper aims to provide empirical evidence of the association between audit committee characteristics and internal audit quality through internal audit professionalization.

Abstract

Purpose

This paper aims to provide empirical evidence of the association between audit committee characteristics and internal audit quality through internal audit professionalization.

Design/methodology/approach

The investigation of the research question was based on 45 usable responses that were received from a survey of chief audit executives from firms listed on the Athens Stock Exchange and combined with publicly available information from annual reports.

Findings

The results indicate that audit committee characteristics (independence, diligence through frequent meetings and interaction with internal audit through valuation) influence internal audit professionalization. In addition, they demonstrate that internal audit professionalization is also influenced by CEO duality and firm’s external auditor.

Practical implications

The findings of this study have implications for audit committees wishing to improve their overall effectiveness, by identifying areas with substantial impact on internal audit quality. Moreover, regulators of corporate governance bodies can also benefit from the results to strengthen audit committee’s efficiency regarding internal audit function oversight.

Originality/value

The results add to the literature on the discussion of internal audit professionalization and complement the work of other researchers in the field of audit committee’s impact on internal audit quality/effectiveness. This study attempts to fill a gap in the literature on the effect of audit committee characteristics on internal audit professionalization, an element introduced from an institutional theory perspective.

This paper aims to explore the effect of interlocking directorates on agency conflicts and corporate performance in the shipping industry.

Abstract

Purpose

This paper aims to explore the effect of interlocking directorates on agency conflicts and corporate performance in the shipping industry.

Design/methodology/approach

The authors use social network analysis to discover central nodes in the network of personal and corporate connections in an international sample of 110 listed shipping companies.

Findings

Assessing network structure, the authors find that the network of corporate leaders is denser than the network of shipping companies. The network of shipping companies is populated with many isolated nodes; the network of shipping executives and directors is populated with many cohesive groups in which the longest distance between two corporate leaders is two companies. The authors find that interlocking corporate leadership can help resolve agency conflicts in the shipping industry, bearing a negative effect on the magnitude of agency costs. The extent of leadership overlaps is associated with board size, financial leverage and profitability. The relationship between profits and interlocks is bidirectional, implying that interlocking directorates bear a positive effect on asset returns.

Originality/value

The authors map the relational structures in the social networks of companies and company leaders in the shipping industry and discover the cross-sectional determinants of interlocks in the shipping industry. The finding about the effect of interlocks on profitability and agency costs bears policy implications for the design of corporate governance in the shipping industry.

Abstract

Purpose

This research aims to build a system that will continuously. This paper is an extended version of SECPRE 2021 paper and presents a research on the development and validation of a behavioral biometrics continuous authentication (BBCA) system that is based on users keystroke dynamics and touch gestures on mobile devices. This paper aims to build a system that will continuously authenticate the user of a smartphone.

Design/methodology/approach

Session authentication schemes establish the identity of the user only at the beginning of the session, so they are vulnerable to attacks that tamper with communications after the establishment of the authenticated session. Moreover, smartphones themselves are used as authentication means, especially in two-factor authentication schemes, which are often required by several services. Whether the smartphone is in the hands of the legitimate user constitutes a great concern and correspondingly whether the legitimate user is the one who uses the services. In response to these concerns, BBCA technologies have been proposed on a large corpus of literature. This paper presents a research on the development and validation of a BBCA system (named BioPrivacy), which is based on the user’s keystroke dynamics and touch gestures, using a multi-layer perceptron (MLP). Also, this paper introduces a new BB collection tool and proposes a methodology for the selection of an appropriate set of BB.

Findings

The system achieved the best results for keystroke dynamics which are 97.18% accuracy, 0.02% equal error rate, 97.2% true acceptance rate and 0.02% false acceptance rate.

Originality/value

This paper develops a new BB collection tool, named BioPrivacy, by which behavioral data of users on mobile devices can be collected. This paper proposes a methodology for the selection of an appropriate set of BB. This paper presents the development of a BBCA system based on MLP.

Abstract

Purpose

The purpose of this paper is to provide an enhanced version of quality function deployment (QFD) that captures customers’ present and future preferences, accurately prioritizes product specifications and eventually translates them into desirable quality products. Under rapidly changing environments, customer requirements and preferences are constantly changing and evolving, rendering essential the realization of the dynamic role of the “Voice of the Customer (VoC)” in the design and development of products.

Design/methodology/approach

The proposed methodological framework incorporates a Multivariate Markov Chain (MMC) model to describe the pattern of changes in customer preferences over time, the Fuzzy AHP method to accommodate the uncertainty and subjectivity of the “VoC” and the LP-GW-AHP to discover the most important product specifications in order to structure a robust QFD method. This enhanced QFD framework (MMC-QFD-LP-GW-Fuzzy AHP) takes into consideration the dynamic nature of the “VoC” captures the actual customers’ preferences (WHATs) and interprets them into design decisions (HOWs).

Findings

The integration of MMC models into the QFD helps to handle the sequences of customers’ preferences as categorical data sequences and to consider the multiple interdependencies among them.

Originality/value

In this study, a MMC model is introduced for the first time within QFD, in an effort to extend the concept of listening to further anticipating to customer wants. Gaining a deeper understanding of current and future customers’ preferences could help organizations to design products and plan strategies that more effectively and efficiently satisfy them.

Abstract

Purpose

The purpose of this paper is to present a new paradigm, named BioGames, for the extraction of behavioral biometrics (BB) conveniently and entertainingly. To apply the BioGames paradigm, the authors developed a BB collection tool for mobile devices named BioGames App. The BioGames App collects keystroke dynamics, touch gestures, and motion modalities and is available on GitHub. Interested researchers and practitioners may use it to create their datasets for research purposes.

Design/methodology/approach

One major challenge for BB and continuous authentication (CA) research is the lack of actual BB datasets for research purposes. The compilation and refinement of an appropriate set of BB data constitute a challenge and an open problem. The issue is aggravated by the fact that most users are reluctant to participate in long demanding procedures entailed in the collection of research biometric data. As a result, they do not complete the data collection procedure, or they do not complete it correctly. Therefore, the authors propose a new paradigm and introduce a BB collection tool, which they call BioGames, for the extraction of biometric features in a convenient way. The BioGames paradigm proposes a methodology where users play games without participating in an experimental painstaking process. The BioGames App collects keystroke dynamics, touch gestures, and motion modalities.

Findings

The authors proposed a new paradigm for the collection of BB on mobile devices and created the BioGames application. The BioGames App is an Android application that collects BB data on mobile devices and sends them to a database. The database design allows multiple users to store their sensor data at any time. Thus, there is no concern about data separation and synchronization. BioGames App is General Data Protection Regulation (GDPR) compliant as it collects and processes only anonymous data.

Originality/value

The BioGames App is a publicly available tool that combines the keystroke dynamics, touch gestures, and motion modalities. In addition, it uses a methodology where users play games without participating in an experimental painstaking process.

Abstract

Purpose

This paper aims to explore internal audit effectiveness through its contribution to corporate governance. Namely, the authors attempt to investigate the impact of internal audit professionalization on internal audit’s contribution to corporate governance.

Design/methodology/approach

Using a research framework informed by institutional theory, the authors predict that internal audit’s contribution to corporate governance is associated with factors related to internal audit professionalization. To investigate the arguments, the authors combine data from a survey of 49 listed companies in the Athens Stock Exchange with publicly available information from annual reports.

Findings

Empirical results indicate that internal audit professionalization affects internal audit effectiveness, as internal audit’s contribution to corporate governance is improved for organizations where internal audit function complies with internal auditing standards and internal auditors hold professional certifications. The findings also suggest that internal audit’s contribution to corporate governance is shaped by some company-specific characteristics, namely, CEO duality and audit committee quality.

Practical implications

The results have implications for internal auditors who wish to increase the efficiency of their work, corporate governance mechanisms such as the board of directors and the audit committee, which can use the findings of this study to better respond to their responsibilities concerning internal audit and regulators who can also benefit to strengthen areas with substantial impact on internal audit’s contribution to corporate governance.

Originality/value

This paper contributes to the academic discussion on the role of internal audit in corporate governance and complements the work of other researchers in the field of internal audit professionalization. This study tries to fill a gap in the literature on the effect of internal audit professionalization elements on internal audit’s contribution to corporate governance.

Abstract

Purpose

Recognizing the fundamental role of quality as a means to differentiate service organizations, the purpose of this paper is to propose a strategic decision making framework for service organizations, which prioritizes performance improvement strategies that are rooted to customer requirements, organizational goals and constrained by organizational resources.

Design/methodology/approach

The proposed framework is realized through the implementation of two stages and four distinct phases mirroring the combination of enhanced quality function deployment (first stage), and zero-one goal programming (second stage). It proposes the utilization of a mix of qualitative and quantitative methods, and the collection of data from multiple sources including customers, middle, and top management.

Findings

The application and validation of the proposed framework utilizes information from both customers and employees in the bank services sector. Overall, results from the specific study revealed that a combination of “reengineering” and “expansion” strategies was more appropriate corresponding to customer priorities, organizational goals and effective utilization of available resources.

Originality/value

The paper presents a novel two stage strategic framework for service organizations. It utilizes a balanced mixture of qualitative and quantitative methods in an effort to capture and delineate elusive customer requirements and design characteristics of services, allowing the assessment of different combinations of quality improvement strategies in response to management objectives.
