Abstract
Purpose
In the present work, we focus on developing an in-house parallel meshless local Petrov-Galerkin (MLPG) code for the analysis of heat conduction in two-dimensional and three-dimensional regular as well as complex geometries.
Design/methodology/approach
The parallel MLPG code has been implemented using open multi-processing (OpenMP) application programming interface (API) on the shared memory multicore CPU architecture. Numerical simulations have been performed to find the critical regions of the serial code, and an OpenMP-based parallel MLPG code is developed, considering the critical regions of the sequential code.
Findings
Based on performance parameters such as speed-up and parallel efficiency, the credibility of the parallelization procedure has been established. Maximum speed-up and parallel efficiency are 10.94 and 0.92 for regular three-dimensional geometry (343,000 nodes). Results demonstrate the suitability of parallelization for larger nodes as parallel efficiency and speed-up are more for the larger nodes.
Originality/value
Few attempts have been made in parallel implementation of the MLPG method for solving large-scale industrial problems. Although the literature suggests that message-passing interface (MPI) based parallel MLPG codes have been developed, the OpenMP model has rarely been touched. This work is an attempt at the development of OpenMP-based parallel MLPG code for the very first time.

Abstract
Purpose
Augmentation of an ISO 10001 code system for healthcare worker (HW) satisfaction with ISO/IEC 27701 and ISO/IEC 29184 privacy-related subsystems is shown. Four specific codes regarding the privacy of HWs using electronic devices for hand hygiene (HH) monitoring and the related activities are presented.
Design/methodology/approach
HWs’ concerns involving automated hand hygiene monitoring technologies were identified through a literature review and classified. Privacy codes (PCs) that deal with such concerns were developed. ISO/IEC 27701 requirements for privacy information were mapped to the elements of these codes, labelled as “Healthcare Workers’ Hand Hygiene Privacy Codes (HW-HH-PCs)”. Both ISO/IEC 27701 and ISO/IEC 29184 guidelines for Privacy Notices and consent were linked with the activities for preparing the code resources.
Findings
Components of an ISO/IEC 27701 system, the guidance of ISO/IEC 29184 and the definitions provided in ISO/IEC 29100 can assist the preparation of HW-HH-PCs and the required resources. An ISO/IEC 29184 Privacy Notice can be used as input for developing an Informed Consent Form, which can be implemented to suit two of the four developed HW-HH-PCs.
Practical implications
HW-HH-PCs and the supporting resources, which healthcare organizations could implement to potentially increase quality assurance of an automated HH monitoring service, are illustrated.
Originality/value
Integrative augmentation of ISO 10001:2018, ISO/IEC 27701:2019 and ISO/IEC 29184:2020 within an underlying framework from ISO/IEC 20000–1:2018 for information technology service, together with the related examples of privacy-related customer satisfaction codes and the corresponding resources, is introduced.

Abstract
Purpose
The purpose of this research is to design and develop a technique for polyphase code design for the radar system.
Design/methodology/approach
The proposed fractional harmony search algorithm (FHSA) performs the polyphase code design. The FHSA binds the properties of the harmony search algorithm and the fractional theory. An optimal fitness function based on the coherence and the autocorrelation is derived through the proposed FHSA. The performance metrics such as power, autocorrelation and cross-correlation measure the efficiency of the algorithm.
Findings
The performance metrics such as power, autocorrelation and cross-correlation is used to measure the efficiency of the algorithm. The simulation results show that the proposed optimal phase code design with FHSA outperforms the existing models with 1.420859, 4.09E−07, 3.69E−18 and 0.000581 W for the fitness, autocorrelation, cross-correlation and power, respectively.
Originality/value
The proposed FHSA for the design and development of the polyphase code design is developed for the RADAR is done to reduce the effect of the Doppler shift.

Abstract
Purpose
This paper aims to analyse the role of the code of ethics as a critical element of responsible management and posits it as a tool that integrates ethics, sustainability and attention to stakeholders. This proposed tool can be a facilitator of integrated management of these dimensions.
Design/methodology/approach
A survey was developed to answer the research questions, and descriptive and factor analyses were carried out. A non-probabilistic sampling technique, purposive sampling, was used. The survey, sent by e-mail, was addressed to managers and decision makers of Spanish companies belonging to associations explicitly committed to corporate social responsibility and ethics; 73 questionnaires were answered. Statistical analyses were performed with SPSS 26.0 software.
Findings
The findings highlight that companies that are showing leadership in ethical management are using their codes of ethics as a key instrument in the business ethics strategy. Codes of ethics go beyond being a guide to ethical conduct to being an instrument at the service of stakeholder relations, sustainability and ethics. The keys that these companies agree on are the design of participative processes of responsible management, the multidimensional content of their codes of ethics and a code management oriented to generate a proactive ethical culture in the company.
Practical implications
This paper proposes a series of recommendations that may be useful to all those companies that wish to promote effective and integrative ethical management through their code of ethics, as much as if they already have one, as they are developing it.
Originality/value
This research highlights the role of code of ethics as an integrative tool for ethics, sustainability and stakeholder responsibility. For that, the keys that these companies agree on are the design of participative processes of responsible management, the multidimensional content of their codes of ethics and code management oriented to generate a proactive ethical culture in the company.

Abstract
Purpose
This study aims to investigate the impact of consumer ethnocentrism on consumers' evaluation of blockchain-based traceability information. It also examined how the use of quick response (QR) codes for traceability affects consumers' evaluation of traceable food products.
Design/methodology/approach
An online choice experiment was conducted to determine consumers' evaluation of the blockchain-based traceability of Feta cheese with a quota sample of 715 Greek consumers. Pearson bivariate correlation and mean comparison were used to examine the relationship between consumer ethnocentrism and QR use behaviour. Random parameter logit models were employed to examine consumers’ valuation of the examined attributes and interaction terms.
Findings
The results show that ethnocentric consumers are willing to pay more for blockchain-based traceability information. Ethnocentric consumers tend to scan QR codes with traceability information. Spending more time reading traceability information embedded in QR codes does not lead to a higher willingness-to-pay (WTP) for traceable food products.
Practical implications
The findings suggest that patriotic marketing messages can draw consumers' attention to blockchain-based traceability information. The modest WTP for and low familiarity with blockchain-based traceability systems raise the need for educating consumers regarding the benefits of blockchain in traceability systems.
Originality/value
This is the first study to provide timely empirical evidence of a positive WTP for blockchain-based traceability information for a processed dairy product. This study is the first to attempt to distinguish the effects of the intention to scan QR codes and reading information embedded in QR codes on consumers’ valuation of food attributes.

Abstract
Purpose
This research informs the intersection of climate and heritage policy development by examining the history of US energy policy as it relates to historic buildings, emerging policy tools to reduce greenhouse gas emissions, and the implications of a changing legislative landscape on historic buildings through the case of New York City.
Design/methodology/approach
This study employs a multi-method approach, including a review of US energy codes; discourse analysis of government records, energy studies, and reports related to historic buildings and energy; select research into energy-related heritage policy at the municipal level; and geospatial and statistical methods to analyze policy implications in the case study of New York City.
Findings
Historic buildings have long been afforded exemptions from energy code compliance in the US, and these waivers are widespread. Contemporary operating energy and greenhouse gas data, as well as energy justice findings about whom these waivers privilege, challenge these exemptions and signal a need for significant policy reform in light of climate change.
Originality/value
This study questions longstanding rhetoric about historic buildings being inherently green and supports the need for more evidence-based research to undergird heritage policy reform that is equitable and climate-responsive.

Abstract
Purpose
The purpose of this study is to provide for critical literature on the legal aspects of corporate governance and their application in Mauritius. The drawbacks of having the principles in the form of a non-binding code are discussed, and a case is made to consider their enshrinement in laws such as the Companies Act 2001 to render them legally enforceable for the good health of companies in Mauritius.
Design/methodology/approach
A doctrinal legal methodology has been adopted to assess the effectiveness of the principles of the 2016 Code of Corporate Governance of Mauritius. Legislations, legal texts, case law and regulations are used to conduct this assessment. In addition, a black-letter approach is taken while discussing the enshrinement of the principles in the Companies Act 2001 of Mauritius. The doctrinal methodology is further supported by a qualitative analysis of the principles of corporate governance based on existing legal literature, which emphasises their relevance and importance.
Findings
The principles of the 2016 Code of Corporate Governance are no doubt a progress over the former 2004 Code in various aspects, aligning the Code with the requirements of the OECD. However, there are still certain loopholes that have been highlighted. In addition, the extent to which these principles are reflected in the Companies Act, which is the primary legislation for companies, has been found to be lacking and inadequate.
Originality/value
This paper is, to the best of the author’s knowledge, the first legal literature concerning the Mauritian legal framework on corporate governance. This is relevant because the country has recently experienced corporate collapses, which could arguably have been avoided with the application of the principles of corporate governance. As such, the paper will present a case study that can be used as a reference for future research on the enforceability and justiciability of these principles.

Abstract
Purpose
This study aims to explore the quality of corporate governance disclosure under an “apply and explain” regime in the context of an emerging economy (Mauritius), following a transition from the traditional “comply or explain” approach within the national code of corporate governance.
Design/methodology/approach
The research relies on a content analysis of corporate governance disclosure in 86 annual reports of companies listed on the Stock Exchange of Mauritius for the financial periods 2018–2019 and 2019–2020, one-way analysis of variance tests and draws on the typology of corporate governance explanations developed by Shrives and Brennan (2015), focusing on specificity, location and comprehensiveness dimensions. This paper draws on legitimacy theory and the concepts of substantive and symbolic disclosures to guide the interpretation of the findings.
Findings
From a specificity point of view, the disclosure index revealed significant variations, with the highest score being four times the lowest score. With regards to location and comprehensiveness, only around half of companies are making optimum use of a corporate governance report and providing explanations by principles. This paper also illustrated how some firms provided symbolic disclosures. Overall, there are disparities in the application of the code by companies, reflected in a blend of substantive and symbolic disclosures to maintain their legitimacy.
Originality/Implications
This study examines “apply and explain” disclosures in a emerging economy in contrast to the “comply or explain” approach studied so far in the literature. Merely professing a “well intended” shift to the “apply and explain” approach does not necessarily lead to improvements in the quality of corporate governance disclosures. Companies, governance professionals and regulatory bodies could formulate disclosure guidance to better underpin the implications of the “apply and explain” approach.

Abstract
Purpose
This paper aims to provide an objective and comprehensive evaluation of the understanding of the professional code of ethics of Indian Professional Management Accountants in Business (PMAIBs). It further delves into their individual, job and organizational characteristics as determinants of their understanding of the code.
Design/methodology/approach
This study relies on data from 247 responses to a survey-based questionnaire. Overall scores and sub-scores of the level of understanding of the code were calculated based on questions grounded in IESBA Code and ethical dilemmas. The drivers of these scores were then examined using one-way ANOVA, OLS, Probit and ordered probit regressions.
Findings
This study found considerable heterogeneity in Indian PMAIBs' understanding of their professional code of ethics and substantial scope for improvements. PMAIBs were stronger in Application, Resolution and Threats but weaker in Theory and Principles. Further, PMAIBs who had ranked themselves higher on code-familiarity, had higher moral maturity, hailed from western India and worked for foreign-listed, foreign-owned firms were found to have a higher level of understanding of the code. Highly educated elderly professionals and professionals with more responsibility areas exhibited a lower level of understanding of the code.
Research limitations/implications
Insights from the study can help professional bodies, employers and academics identify and segment PMAIBs based on their ethics-training needs and customize interventions, which can benefit businesses and society through reduced corporate ethical failures. Considering the risk implications of Indian PMAIBs' inadequacies in understanding their code of ethics, the Indian professional accounting organization (ICAI-CMA) should mandate ethics in continuing professional development and expedite its long pending convergence with the IESBA code, a global benchmark for professional accountants.
Originality/value
This paper assesses the understanding of the professional code of ethics of PMAIBs, which is crucial yet amiss in the accounting ethics literature. While ethical decision-making is extensively researched, how well the professionals understand their code is yet unexplored. Research on PMAIBs, despite their unique ethical vulnerabilities and increasingly vital role in organizations, is still dormant. This study aims to fill these gaps by examining PMAIBs from India, an emerging economy under-represented in accounting ethics literature. India offers an important and rich setting for the study due to its large size, fast growth, deep integration with the global economy, high perceived corruption levels and poor ethical behavior of its firms.
