AbstractExtrapulmonary complications of different organ systems have been increasingly recognized in patients with severe or chronic Coronavirus Disease 2019 (COVID-19). However, limited information on the skeletal complications of COVID-19 is known, even though inflammatory diseases of the respiratory tract have been known to perturb bone metabolism and cause pathological bone loss. In this study, we characterized the effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on bone metabolism in an established golden Syrian hamster model for COVID-19. SARS-CoV-2 causes significant multifocal loss of bone trabeculae in the long bones and lumbar vertebrae of all infected hamsters. The bone loss progressively worsens from the acute phase to the post-recovery phase. Mechanistically, the bone loss was associated with SARS-CoV-2-induced cytokine dysregulation which upregulates osteoclastic differentiation of monocyte-macrophage lineage. The pro-inflammatory cytokines further trigger a second wave of cytokine storm in the skeletal tissues to augment their pro-osteoclastogenesis effect. Our findings in this established hamster model suggest that pathological bone loss may be a neglected complication which warrants more extensive investigations during the long-term follow-up of COVID-19 patients. The benefits of potential prophylactic and therapeutic interventions against pathological bone loss should be further evaluated.Abstract FigureGraphical abstractSARS-CoV-2 infection causes pathological bone loss in golden Syrian hamsters through induction of cytokine storm and inflammation-induced osteoclastogenesis.
Corrosion performance and morphological analysis of activated zinc phosphate coating formed on steel surface
Authors: Abdalla Khalid , Zuhailawati Hussain 
Published: October 2021

Purpose
The purpose of this paper is to study the effect of different concentrations of pretreatment solution of copper acetate (1, 5 and 10 g/L) on the deposition, growth and protection ability of zinc phosphate coating.

Design/methodology/approach
Zinc phosphate coatings were deposited on steel surface by immersion method. Scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS) were used to study the morphological evolution and chemical analysis of formed coatings. The electrochemical performance of the coatings was evaluated via potentiodynamic polarization curves, electrochemical impedance spectroscopy (EIS) and immersion test in an aerated 3.5% NaCl solution.

Findings
The results showed that the activation treatment accelerated the deposition of the phosphate coating and improved its surface coverage. A higher phosphate coating weight (7.35 g/m2) and more compact structure was obtained with pretreatment solution of 1 g/L copper acetate. Electrochemical results revealed that the protection ability of the phosphated substrates was markedly enhanced after the pretreatment, and the best corrosion protection was obtained with a concentration of 1 g/L copper acetate solution. The corrosion current density of phosphated substrate was reduced by 64.9% after activation treatment with 1 g/L copper acetate solution.

Originality/value
In this investigation, dense, stable and compact zinc phosphate layers with improved corrosion resistance were formed on a carbon steel surface after activation pretreatment with copper acetate solution prior to a phosphating step.

Authors: Nguemgaing Hélène Flore , Sant’Anna Ana Claudia 
Published: October 2021

PurposeHow has COVID-19 impacted meat processors' stock returns? The authors evaluate the effects of supply chain disruptions (e.g. lockdowns and COVID-19 incidences among workers) on stock market prices of meat processors during the COVID-19 pandemic.Design/methodology/approachThis study uses an event study approach to examine the disruptions from COVID-19 through events such as plant shutdowns, the pandemic announcement, lockdown dates and the first case of COVID-19 outbreaks in meat processing plants. The dataset includes S&P 500, Google Trends, financial beta and data collected for 14 US publicly traded meat processing companies.FindingsResults show that nationwide events (e.g. announcement of the pandemic) had no statistically significant impact on average abnormal returns of meat processing companies. Individually, however, firms experienced negative abnormal returns. COVID-19-related events in individual meat processing companies had a temporary negative abnormal return in the days prior to the event.Originality/valueThis study has two main contributions. First, the authors estimate the effect of COVID-19 on the returns of meat processors. Second, the authors use Google Trends to estimate the expected stock markets returns of meat processing companies. This study provides insight to investors on the behavior of industry returns from events such as outbreaks that affect human health.

Published: October 2021

PurposeThe purpose of this study is to examine the association between audit committee effectiveness (ACE), internal audit function (IAF) and sustainability reporting practices.Design/methodology/approachUsing a cross-sectional and correlational design, useable questionnaires were received from 48 financial services firms in Uganda. The data were analyzed using Statistical Package for Social Sciences.Findingsresults indicate that ACE and IAF are positively and significantly associated with sustainability reporting practices. ACE and IAF are more significantly associated with economic and social indicators than environmental sustainability indicators.Research limitations/implicationsIn terms of practice, it is no longer a matter of having internal auditors and audit committees in place but rather those who are mindful of the welfare of society and the natural environment. The effectiveness of the board audit committee and a functioning internal audit can be assessed in terms of their recommendations and decisions regarding improvements in the welfare of society and the natural environment in addition to the traditionally known performance benchmarks.Practical implicationsThe study focuses on only financial services firms in Uganda, and this is a small sample. Future studies may focus on larger samples to enable comparison of the results.Originality/valueThis study provides insights on the initial understanding of the association between ACE, IAF and sustainability reporting practices using evidence from a developing African country – Uganda.

Authors: Gisbert-Trejo Nuria , Albizu Eneka , Landeta Jon , Fernández-Ferrín Pilar 
Published: October 2021

Purpose
This article aims to present the differences in implementation between individual mentoring programs (IMPs) and group mentoring programs (GMPs).

Design/methodology/approach
This exploratory study used semi-structured interviews with 16 experts: mentoring program (MP) coordinators, consultants and mentors. During the interviews, the steps in implementing a mentoring program were reviewed and discussed by practitioners.

Findings
Based on the interviews and contrasting with the proposed implementation model, the authors compared IMPs and GMPs. The results highlight the role of the GMP coordinators, especially in the selection of mentors, mentees and generating resources that favor the beneficial effects of group dynamics on mentoring processes.

Practical implications
This model for implementing MPs and the differences identified between IMPs and GMPs provide practical help to program coordinators (PCs) and mentors to deploy MPs by highlighting the relevant aspects.

Originality/value
Mentoring is a Human Resource Development (HRD) technique whose implementation at the program level needs further deepening for practitioners. This is the first work that emphasizes the differences to be considered in the design and implementation of MPs by taking the individual or group dimension of mentoring.

Published: October 2021

PurposeThe purpose of this research is to examine the impact of work–life balance on project performance with mediating role of job burnout and moderating role of organizational support and what are the indirect effects of work–life balance on project performance via organizational support. For quantifying this effect, regression analysis has been used, and to calculate variable mediation, moderation and conditional process analysis, Model of Preacher and Hayes has been utilized.Design/methodology/approachFour variables and 23 measurement items have been extracted from published literature. Further, data collection for this research study has been conducted through the “Questionnaire” technique. The questionnaire has been developed based on previously established questions available in the literature. Finally, to obtain a more objective assessment, a statistical model is developed, and regression analysis is performed to highlight the most significant variables that impact the project performance.FindingsThe results of the study show that work–life balance harmed project performance, and organizational support was putting the main impact on project performance. Moreover, the findings of the study include the positive association of job burnout with project performance. And a total mediation effect was observed between work–life balance and project performance, through the bootstrapping results.Practical implicationsThe authors have found that the theoretical model got practical implications, both for the managers and the organization involved in the project. The first implication is that adopting suitable work–life balance practices will be beneficial and support professionals working on projects. Professionals engaged in projects, both at managerial and team levels, are exposed to work–life balance resulting from work performance and personal life responsibilities. The empirical results revealed conflicts came across due to poor time management, and these conflicts have adverse effects on personal and professional commitments. It should be one of the basic considerations for project-based organizations, to make available ample time for the professionals to be with their families.Originality/valueThis study has enabled the authors to understand the work–life balance, organizational support and job burnout and how these variables affect project performance via their relationship as described in a theoretical framework. Furthermore, this research contributes toward the field by considering different ways to balance the work–family conflicts by examining the effects of work–life balance on Job Burnout and Project Performance. This study brought some significant insights and one of its kind in the developing countries and adds to the existing body of knowledge by developing a regression model that will help decision makers and top management to further enhance their project performance.

Published: October 2021

PurposeThis paper aims to examine adaptive livelihood strategies used by small-scale fishing households in the two coastal communities in Central Vietnam under the context of climate change-related stressors.Design/methodology/approachField data were collected through mixed quantitative and qualitative methods including a review of secondary data, key-informant interviews, group discussions and household surveys with 300 sampled fishing households. The qualitative data support the analysis and discussion of quantitative data.FindingsThe results showed local households’ perception of the presence and influence of multiple non-climate and climate stressors on their fishery-based livelihoods in terms of employment and income in many ways. The affected households exerted to develop a diversity of adaptation methods within and out of fishing to sustain their livelihoods and cover a deficit in household income. The household socio-demographic characteristics particularly education, labour force, fishing equipment and social support played significant importance in characterising the categories of adaptation strategies among the survey households. The role of local governments in creating an enabling environment for local-level adaptation, as well as protecting marine and coastal ecosystems was rather limited despite their recognized importance.Originality/valueThe paper provides an empirical case of how small-scale fishing households in coastal communities in Central Vietnam are adapting to climate-related stressors. It suggests policy should promote livelihood diversification opportunities and address household-level constraints for adaptation. Fisheries management plan is urgently needed to control illegal fishing activities for sustainable use of coastal and marine fishery resources and the appropriate mechanism is important to stretch local governments’ resources for better supporting local-level adaptation.

Published: October 2021

PurposeAlthough Industry 4.0 has created a digital disruption in the business world, there is a huge demand for competent personnel to adapt to innovation in a highly volatile environment. This study aims to develop a conceptual framework on innovation adoption, thus creating a sustainable business performance in the Indian automobile industry.Design/methodology/approachA sample of 272 employees working in the Indian automobile industry was empirically tested to examine the hypothesized relationships. The proposed relationships were further tested using structural equation modelling (SEM) with AMOS 26 software.FindingsResults highlight that knowledge management, climate for innovation, learning agility and internal corporate communication positively affect innovation adoption. Perceived innovation characteristics also have a significant relationship with innovation adoption and sustainable business performance. Furthermore, innovation adoption has a positive relationship with sustainable business performance. However, ambidextrous leadership has a non-significant relationship with innovation adoption.Research limitations/implicationsThis study was confined to the Indian automobile industry, which restricts its generalizability. Thus, future research can be conducted in other sectors and country contexts.Practical implicationsThe paper provides valuable insights to practitioners, HR professionals and managers to develop an agile talent who quickly adapts innovative practices to deliver desired results. Organizations must incorporate digital leadership style, robust knowledge management, climate for innovation, learning agility and corporate communication into their talent development practices that further enhance strategic capabilities and lessen expenditures.Originality/valueThis paper provides a holistic framework of innovation adoption in the Indian automobile industry to attain sustainable business performance.
How cultural dimensions are shaping social expectations: the case of European state-owned enterprises' nonfinancial reporting
Authors: Zanellato Gianluca , Tiron-Tudor Adriana 
Published: October 2021

PurposeThe purpose of the research is to shed light on how the mandatory regulation on nonfinancial information has changed European state-owned enterprises' (SOEs) disclosure levels. In addition, the present research aims to demonstrate, under the lens of legitimacy theory, how Hofstede's cultural dimensions shape social expectations that may have suffered changes after the introduction of a mandatory regulation on nonfinancial reporting.Design/methodology/approachThe paper adopts a mixed approach. First, it employees the content analysis to investigate the disclosure level on 22 of the 24 European SOEs. Second, the authors demonstrate how cultural dimensions take a different role when a change in regulation is introduced using the qualitative comparative analysis (QCA).FindingsThe results reveal a slight increase in disclosure from the year before introducing the directive. Additionally, the results demonstrate how none of Hofstede's cultural dimensions is responsible for high disclosure levels. Although, the sufficiency analysis outlines several combinations of different cultural dimensions that lead to high disclosure levels. In particular, results demonstrate how the core dimensions leading to the outcome changed once the European Union Directive (EUD) has entered into force.Research limitations/implicationsDespite the contributions, the present study is not free of limitations. As the investigated sample is limited to a small number of SOEs, the content analysis adopts a dichotomous approach. The analysis is conducted on integrated reporting, and the fuzzy set QCA results cannot be used for generalization but refer only to the investigated sample. Consequently, further studies should investigate a broader sample of SOEs and organizations that adopt other nonfinancial reporting frameworks. Additionally, a qualitative approach to the reports' analysis is recommended.Practical implicationsIt demonstrates how the EUD on nonfinancial information has impacted the disclosure levels of European SOEs. It adopts a fresh methodology rarely used in accounting. It demonstrates how cultural conditions influence social expectations that determine corporations to disclose more information after the introduction of a regulatory framework.Originality/valueThe paper's theoretical contribution refers to its focus on the public sector, and it adopts a methodology rarely used by accounting scholars.
Is the vitality of Malaysian academics at stake?

Published: October 2021

PurposeAcademic vitality and burnout studies can help the university administrators and lecturers to develop a quality education and provide more conducive working environments. Hence, understanding and fostering what contributes to faculty and institutional vitality is central to prevent burnout during times of change. Therefore, the purpose of the study is to investigate the level of vitality amongst lecturers in Malaysia and to see if there is any significant difference in vitality between the subgroups of the demographic variables.Design/methodology/approachThe study was conducted on 379 academicians from selected public and private universities, polytechnics and university colleges. Data were collected via Survey Monkey application. Descriptive analysis was conducted where mean values, standard deviation and median were calculated. Analysis of variance (ANOVA) was conducted to see whether there is significant difference in vitality between the subgroups of the demographic. Additionally, Box and Whiskers plot was used to analyse the outliers to further scrutinise the extremely low mean scores. Open ended responses were also analysed to support the statistical analysis.FindingsResults obtained reveal that almost 25% of the respondents indicate high vitality; another 25% are moderately vital; while about 50% fall under the group of low to very low vitality. Only administrative posts were found to have a significant difference in overall vitality, while age, gender, number of children, income level, working experience and teaching field showed no significant difference.Originality/valueThis paper differs from other previous studies as it defined the different levels of vitality amongst academics based on quartiles. One important contribution of this paper is the use of the slider scale with percentage as the scoring units that provide an infinitesimal rating option that enriches the collected data and enables application of mathematical operations, such as the mean. The use of this slider scale had also facilitated the analysis of outliers due to the scale’s discriminative feature to scrutinise those considered as outliers.
