Authors: Rodrigo M.N.N. , Perera Srinath , Senaratne Sepani , Jin Xiaohua 
Published: July 2021

PurposeBlockchain as an emerging technology has increased the interests within various industries because of its salient features. A potential application of blockchain for embodied carbon (EC) estimating is being explored. Though there are several databases/tools to estimate EC, the accuracy of estimates prepared using them is affected due to several limitations. As a solution, a prototype blockchain-based EC (BEC) Estimator for distributed supply chain-based EC estimating has been introduced. The data models and user flow diagram that lead to development of a BEC Estimator are developed and evaluated in this study.Design/methodology/approachA case study approach assisted in developing the data models and user flow diagram for the BEC Estimator. A Delphi-based expert forum was used to evaluate and produce the refined data models and user flow diagram.FindingsThe BEC Estimator adopts a waterfall model, a system development lifecycle model, in developing the application. The phases, system analysis and system design, consisting the development of the data models and user flow diagram for the BEC Estimator are discussed.Originality/valueEstimating EC accurately plays an important role in construction. The BEC Estimator uses the supply chain based embodied carbon estimating method to estimate EC accurately. This paper demonstrates the data models and user flow diagram developed for the BEC Estimator.
Evaluation and analysis of SDG reporting: evidence from Africa
Authors: Erin Olayinka Adedayo , Bamigboye Omololu Adex 
Published: July 2021

Purpose
The 2030 Agenda and the sustainable development goals (SDG) have gained considerable attention in research and public debate. This calls for accounting research on the subject of SDG disclosure. Based on this premise, this paper aims to evaluate and analyze the extent of SDG reporting by 80 listed firms from 8 selected African countries for the period of 2016 to 2018.

Design/methodology/approach
The study adopts a content analysis and survey method to evaluate the extent of SDG reporting by the selected African countries. This paper conducted content analysis through the use of the PricewaterhouseCoopers (PwC) framework and Global Reporting Initiative (GRI) framework to gauge the extent of firms’ compliance with SDG reporting. Also, this paper uses the business reporting indicators for each SDG developed by GRI to determine the compliance level of the selected firms regarding SDG reporting. The survey was targeted at the big four audit firms (PwC, KPMG, Ernst and Young and Deloitte and Touche).

Findings
The evaluation of SDG disclosure by the 80 listed firms in Africa is still at a very low level except for South African firms. Also, the findings of the business reporting indicators for each SDG target show that most of the firms show little or no concern to report on SDG activities. The result of the research survey indicates that voluntary disclosure, lack of management commitment, lack of regulatory enforcement and cost implications account for low SDG disclosure by the selected African firms.

Research limitations/implications
This study fails to consider the qualitative research approach in determining the extent of SDG disclosure in Africa, as the study did not allow respondents to freely express their opinion on SDG disclosure, as a large part of the survey used close-ended questionnaires.

Practical implications
This study’s findings call for clear responsibility and a strong drive for SDG performance from corporate institutions in Africa. While the overall responsibility rests on the government, the actualization of SDG cannot be achieved without support from corporate organizations. The empirical approach used in this study emphasizes the need for corporate organizations to embrace sustainable practices and to integrate SDG information into their reporting cycle.

Originality/value
This study contributes to growing literature in the area of corporate reporting, sustainability reporting and SDG research in Africa and other emerging economies. Also, this study provides original insight into the contribution of accounting research toward the achievement of SDG.

Authors: Cardinali Vieri , Castellini Marta , Cristofaro Maria Teresa , Lacanna Giorgio , Coli Massimo , De Stefano Mario , Tanganelli Marco 
Published: July 2021

PurposeThis paper aims to contribute to the discussion of the experimental campaigns on Cultural Heritage buildings. By adopting integrated procedures it is possible to limit the invasiveness of the destructive techniques leading to reliable results. The purpose is the proper definition of the structural system, which represents the starting point of the following analysis's phases, not treated in this work. A methodology based on normative references and acknowledged non-destructive and partial destructive strategies has been conceived. The latter aims to an accurate comprehension of the structural information.Design/methodology/approachAn integrated approach for the structural assessment of cultural heritage buildings is presented. The methodology defines an interdisciplinary procedure based on normative references, non-destructive and minor-destructive techniques. A funnel-shaped workflow is developed to characterize the structural system of the buildings. The non-destructive campaigns are widely extended. Then, in-depth analysis concerning partial demolitions and minor-destructive tests are performed. The dynamic identification of the building is executed to detect its global response. The final validation of the assumed mechanical values is obtained by comparing the experimental modes coming from the ambient vibrations and the analytical modes of the structural modelling.FindingsThis research belongs to the Protocol signed between the Municipality of Florence and Department of Earth's Science and Department of Architecture of the University of Florence for the seismic vulnerability assessment of relevant and strategic buildings.Research limitations/implicationsThe descripted methodology is targeted for monuments and special buildings where the use of destructive techniques is not possible or unrecommended.Social implicationsSocial implications are related to the conservation of Heritage buildings. The latter deals with: (1) risk assessment of the targeted buildings towards different hazard sources (e.g. earthquakes, floods); (2) knowledge path developed through non-invasive diagnostic campaigns oriented to the conservation of the manufact. Furthermore, the paper encourages towards the recognition of non-destructive techniques and ambient vibration tests for the achievement of higher knowledge levels.Originality/valueThis paper defines a funnel-shaped procedure defining hierarchical roles between the different available strategies. The originality of this contribution is firstly related to the methodological flowchart. It is targeted to limit the invasive tests and consequently achieving accurate levels of knowledge. Secondly, some novelty can be found in the adoption of improvement parameters from a regional database adopting a Bayesian approach.

Authors: Papadaki Maria , Karamitsos Ioannis , Themistocleous Marinos 
Published: July 2021

PurposeThe purpose of this study is to investigate how healthcare and public organizations can control and monitor digital health test certificates with citizens or other stakeholders using Blockchain platforms. The paper reviews and analyses the literature by focusing on keywords like “Blockchain AND COVID-19”. In response to the 2019 pandemic, most local governments closed their borders and imposed movement restrictions, impacting the global economy, peoples' mobility and everyday life. This study aims to provide a solution to how Blockchain technology can improve the socioeconomic impacts of coronavirus disease 2019 (COVID-19) by enhancing people's mobility and achieving a balance between protecting individuals' rights and public health safety.Design/methodology/approachThis research utilized machine learning bibliometric tools for investigating the normative literature in the area of blockchain and COVID-19. The article conducts a systematic literature review and develops a bibliometric map based on Plevris et al.’s (2017) method.FindingsThis study indicates that there is limited literature on the use of blockchain technology in issuing and validating COVID-19 tests. The development of such solutions can be done through the utilization of smart contracts, and it is expected to increase mobility in a secure and trusted environment that will help in monitoring and slow down the spread of the pandemic.Research limitations/implicationsThis analysis is done during the first ten months of the pandemic outbreak, and there is still limited scientific literature investigating blockchain and COVID-19 concepts.Practical ImplicationsOrganizations are rethinking their information management due to the COVID-19 pandemic for creating better value for the enterprise and all associate stakeholders. Blockchain technology helps organizations to move from a centralized to a decentralized way of information managing. The decentralization of information in the health-care sector will create a better value for all involved stakeholders and radical change in how health-care data are managed and controlled. The implementation of blockchain applications in the health-care industry will result in a more secure, visible, auditable environment accessible by all the parties involved.Originality/valueIt was identified that there is currently limited research done on aligning smart contracts structure within the health-care sector. Therefore, while the current literature demonstrates the importance of aligning the key concepts, little research is done on considering people’s mobility and cross-country communication.
Why do eligible successors withdraw from the succession process in family businesses? A social exchange perspective
Authors: Rodriguez Serna Lil , Nakandala Dilupa , Bowyer Dorothea 
Published: July 2021

PurposeSuccessors' unwillingness to participate in the family business is known to impede intergenerational succession. However, little is known about why those considered eligible, do not choose to become the next chief executive officer (CEO). The authors investigate why some eligible successors withdraw from the succession process while others remain involved. The purpose of this paper is to build theory for which the authors made use of purposive sampling techniques that complied with certain criteria.Design/methodology/approachThe authors use an inductive, exploratory multi-case study design and investigate six Australian food manufacturers.FindingsThis paper's analysis reveals that successors' decisions are driven by dimensions: pursued outcome and reciprocity. Eligible successors withdrawing from succession are concerned about personal financial sustainability and the business' growth potential; this is accompanied by negative exchanges with the incumbent.Research limitations/implicationsThe authors studied a limited number of organizations and these were mainly managed by owner/founders. In this type of organization, successors have been widely exposed to the business and its struggles from an early age. Differences can be present in businesses managed by later generations whose emotional investment, therefore, socio-emotional needs might be different from the cohort being investigated. Second, the authors' aim in carrying out this study was to build theory for which we made use of purposive sampling techniques that complied with certain criteria. Further studies aiming at generalizable results would shed light on the usefulness of the typology and whether other rules apply to the incumbent–successor relationship while ascertaining how the exchanges contribute to the successor's decision to remain or withdraw from the family business.Practical implicationsThis study reveals the crucial nature of the incumbent in the succession process. Their role is not limited to how they interact with the successor but how deeply incumbents manage to understand and monitor the successor's motivations and concerns. Incumbents aiming at retaining eligible successors need to thoroughly understand successors' motivations for agreeing to become the next CEO.Originality/valueThis paper is one of the first to investigate successor withdrawal post training. The authors' methodology includes the responses of non-family senior managers to provide an objective view on the family dynamics.
The impact of green growth on financial stability
Authors: Jadoon Imran Abbas , Mumtaz Raheel , Sheikh Jibran , Ayub Usman , Tahir Mohammad 
Published: July 2021

Purpose
The international institutions, policymakers and governments are promoting green growth as a policy objective for global financial stability (FS) without sound empirical investigation. Therefore, the purpose of this study is to investigate whether the green economy would be successful in achieving its main objective i.e. stabilizing the world financial system because the investment stakes are too high for this green transition.

Design/methodology/approach
The study used the two-step system generalized method of moments (GMM) methodology on panel data of 90 countries for 6 years from 2010 to 2015 to investigate the impact of green growth economy on FS.

Findings
The results of the current study revealed that overall green growth enhanced FS in the country for both the short and long run. However, the social inclusive dimension of green growth was irrelevant in creating FS.

Research limitations/implications
The results of the current study validate the growth-led finance hypothesis and encourage the policymakers to strengthen the policy initiative for green growth. Because green growth mitigates economic and environmental risk to create a stable financial environment. However, social inclusiveness needs to be explored through alternate paradigm in relevance to FS.

Originality/value
As per the author’s knowledge, it is a pioneer study to empirically investigate the impact of green growth on FS which would be useful in understanding the green growth and FS dynamics.
How and when abusive supervision influences knowledge hiding behavior: evidence from India
Authors: Agarwal Upasna A. , Avey James , Wu Keke 
Published: July 2021

PurposeThis study aims to investigate the differential roles of self-esteem and co-rumination in the mediated relationship between abusive supervision and knowledge hiding via psychological safety.Design/methodology/approachThe study used a three-wave time-lagged design and data were collected from 388 full-time employees in India.FindingsThe results show that psychological safety mediated the impact abusive supervision had on knowledge hiding. Further, this impact was weakened by higher self-esteem as employees with higher self-esteem were less affected by the impact of abusive supervision on psychological safety and knowledge hiding; but this impact was amplified by more co-rumination as employees who co-ruminated more were also more affected by abusive supervision in psychological safety and knowledge hiding.Research limitations/implicationsA cross-sectional design and the use of self-reported questionnaires are a few limitations of this study.Originality/valueThis study took a purposeful deviation from the traditional path of organizational justice to the study of abusive supervision and psychological safety and endeavored an alternate route, one of resource conservation. Further, employees have diverse reasons that heighten or dampen their inclination to hide knowledge from others in the workplace. The study examines co-rumination and self-esteem as possible boundary conditions.
Organizational justice and organizational citizenship behaviour: the mediating role of psychological ownership
Authors: K Jnaneswar , Ranjit Gayathri 
Published: July 2021

PurposeThe purpose of this paper is to propose and empirically test a model that examines psychological ownership as an intervening variable between organizational justice and organizational citizenship behaviour drawing on the social exchange theory, equity theory and event mediated model.Design/methodology/approachThe study was based on a cross-sectional research design, with a sample of 301 full-time employees from various information technology organizations in India. Amos software was used to test the validity of the hypothesised model, and PROCESS macro was used to test the mediation of psychological ownership.FindingsThe findings showed that organizational justice impacted both psychological ownership and organizational citizenship behaviour. Furthermore, psychological ownership impacted the organizational citizenship behaviour of employees. The key finding of this study is the partial mediation of psychological ownership in the relationship between organizational justice and organizational citizenship behaviour.Practical implicationsBesides enriching the organizational behaviour literature, the findings of the study offer valuable messages to the organizational leaders in creating sustained competitive advantage through employee behaviours like organizational citizenship behaviour and psychological ownership.Originality/valueEven though the literature reports the impact of organizational justice on organizational citizenship behaviour, the majority of this research is based on a western context. There is little research work done to examine the direct relationship between these variables in a non-western context, especially in an emerging economy like India. This study bridges this research gap and enriches the literature by elucidating how organizational justice impacts organizational citizenship behaviour by evincing the mediating mechanism of psychological ownership. Moreover, this is one of the primary studies that explore the mediating role of psychological ownership in the relationship between organizational justice and organizational citizenship behaviour.
A review on research of fire-induced progressive collapse on structures
Authors: M. Vishal , K.S. Satyanarayanan 
Published: July 2021

Purpose
This paper delineates a literature review on fire-induced progressive collapse on structures and the effect of high temperature on structures and elements. After the occurrences of fire in the World Trade Center in the USA, the researchers started concentrating on the progressive collapse that happens due to high temperature. Currently, most of the researchers are working on fire-induced progressive collapse on structures using high-temperature behavior on materials which are used for construction. The researchers have been doing an intensive study to find a better strategy to prevent the building from structural fire damage or collapse with available codes and guidelines throughout the world. This paper aims to provide a better understanding and analytical solutions on the basis of the recent works done by researchers in fire-induced progressive collapse and methods adopted to find the collapse mechanism.

Design/methodology/approach
This paper is written by studying different literature papers of 109 related to progressive collapse on structures and fire-induced progressive collapse.

Findings
The behavior of structures due to high temperature and collapse conditions due to fire in different scenarios is identified.

Originality/value
This paper fulfills an identified need to study how the structure can withstand high-temperature conditions in our day-to-day lives.

Authors: Upasiri Irindu , Konthesingha Chaminda , Nanayakkara Anura , Poologanathan Keerthan , Nagaratnam Brabha , Perampalam Gatheeshgar 
Published: July 2021

Purpose
In this study, the insulation fire ratings of lightweight foamed concrete, autoclaved aerated concrete and lightweight aggregate concrete were investigated using finite element modelling.

Design/methodology/approach
Lightweight aggregate concrete containing various aggregate types, i.e. expanded slag, pumice, expanded clay and expanded shale were studied under standard fire and hydro–carbon fire situations using validated finite element models. Results were used to derive empirical equations for determining the insulation fire ratings of lightweight concrete wall panels.

Findings
It was observed that autoclaved aerated concrete and foamed lightweight concrete have better insulation fire ratings compared with lightweight aggregate concrete. Depending on the insulation fire rating requirement of 15%–30% of material saving could be achieved when lightweight aggregate concrete wall panels are replaced with the autoclaved aerated or foamed concrete wall panels. Lightweight aggregate concrete fire performance depends on the type of lightweight aggregate. Lightweight concrete with pumice aggregate showed better fire performance among the normal lightweight aggregate concretes. Material saving of 9%–14% could be obtained when pumice aggregate is used as the lightweight aggregate material. Hydrocarbon fire has shown aggressive effect during the first two hours of fire exposure; hence, wall panels with lesser thickness were adversely affected.

Originality/value
Finding of this study could be used to determine the optimum lightweight concrete wall type and the optimum thickness requirement of the wall panels for a required application.
