AbstractWhile the COVID-19 pandemic caused by SARS-CoV-2 has posed a threat to public health as the number of cases and COVID-19-related deaths are increasing worldwide, the incidence of the virus infection are extremely low in Japan compared with many other countries. To explore the reason for this strange phenomenon, we hypothesized the high prevalence of “natural” secretory IgA in saliva as mucosal IgA reacting with SARS-CoV-2, and thus surveyed the positivity for, as well as levels of, such reactive salivary IgA in a cohort of Japanese people of a wide range of age. The major findings were that 95/180 (52.78 %) of overall individuals who had not been exposed to SARS-CoV-2 were positive for salivary IgA with the levels ranging from 0.002 to 3.272 ng/ml, and that there may be a negative trend in positivity for salivary IgA according to age. These results suggest a role of mucosal IgA in host defense against SARS-CoV-2 infection.One Sentence Summary“Natural” secretory immunoglobulin A autoantibodies may play a role in mucosal defense against SARS-CoV-2.
Does internationalization encourage state-owned enterprises to utilize subsidies to innovate? Evidence from high-tech and automobile manufacturing industries of Chinese listed companies
Authors: Xie Yu , Boadu Francis , Tang Hongjuan 
Published: January 2022

PurposeDrawing on the resource-based view, institutional logic and isomorphic pressure theories, this study constructed a theoretical model to explore the correlations between government subsidies and innovation performance. Particularly, this study aims to investigate the moderating effects of ownership types and degree of internationalization on these relationships.Design/methodology/approachTo empirically test the relationships, the authors use panel data from high-tech manufacturing and automobile manufacturing industries in Chinese A stock listed companies for the period 2011–2015 and performed regression analysis.FindingsResults indicate that government subsidies positively enhance enterprises’ innovation performance; there is a big gap between government subsidies’ incentive effect on innovation performance between state-owned enterprises (SOEs) and private-owned enterprises (POEs); with the improvement of internationalization, the promotion effect of government subsidies on enterprise innovation performance is strengthened; there is a three-way interaction between government subsidies, degree of internationalization and ownership types, such that in the presence of a low degree of internationalization, there is a big gap in the incentive effect of government subsidies on the innovation performance of SOEs and POEs; in the presence of a high degree of internationalization, the gap is significantly reduced.Originality/valueThis is an empirical study on the impact mechanism of ownership types and internationalization on the relationship between government subsidies and innovation performance in China. It provides valuable insights to show how internationalization can dramatically improve SOEs’ efficiency disadvantages in the allocation of government subsidies to innovation activities.
Impact of organizational dynamic capability on international expansion and the moderating role of environmental dynamism
Authors: Chatterjee Sheshadri , Chaudhuri Ranjan , Vrontis Demetris , Thrassou Alkis 
Published: January 2022

Purpose
The purpose of this study is to examine the impact of dynamic capability (DC) of organizations on international expansion and further investigate the moderating role of environmental dynamism in the same context.

Design/methodology/approach
Based on the dynamic capability view (DCV) theory and related literature on international business strategy, a theoretical model is developed. This model is subsequently validated with the structural equation modelling technique through a survey of 324 respondents from Indian organizations. The study also examines the moderating impacts using the multigroup analysis method.

Findings
The study finds that organizations’ sensing, seizing and transformational capabilities impact positively and significantly on international marketing capability, as well as on technological innovation capability, which positively and significantly impacts organizations’ international expansion ability. The study also finds that there is a significant moderating impact of environmental dynamism on organizations’ international expansion.

Research limitations/implications
This study has provided a unique theoretical model which can explain the factors impacting organizations’ ability toward international expansion. The study also provides vital insights and directions to practitioners, researchers and academicians on the international business strategy for the expansion of organizations. The theoretical model, however, cannot be generalized, as data was taken only from Indian firms.

Originality/value
The study adds to the body of knowledge of international business strategy, international marketing strategy and technological innovation, adding to the scant research on the relationship between organizations’ DC and the international expansion strategy through a unique and tested model with an explanative power of 73%.
Statistical process monitoring for e-waste based on beta regression and particle swarm optimization
Authors: Oliveira Sant’Anna Angelo Marcio 
Published: January 2022

PurposeE-waste management can reduce relevant impact of the business activity without affecting reliability, quality or performance. Statistical process monitoring is an effective way for managing reliability and quality to devices in manufacturing processes. This paper proposes an approach for monitoring the proportion of e-waste devices based on Beta regression model and particle swarm optimization. A statistical process monitoring scheme integrating residual useful life techniques for efficient monitoring of e-waste components or equipment was developed.Design/methodology/approachAn approach integrating regression method and particle swarm optimization algorithm was developed for increasing the accuracy of regression model estimates. The control chart tools were used for monitoring the proportion of e-waste devices from fault detection of electronic devices in manufacturing process.FindingsThe results showed that the proposed statistical process monitoring was an excellent reliability and quality scheme for monitoring the proportion of e-waste devices in toner manufacturing process. The optimized regression model estimates showed a significant influence of the process variables for both individually injection rate and toner treads and the interactions between injection rate, toner treads, viscosity and density.Originality/valueThis research is different from others by providing an approach for modeling and monitoring the proportion of e-waste devices. Statistical process monitoring can be used to monitor waste product in manufacturing. Besides, the key contribution in this study is to develop different models for fault detection and identify any change point in the manufacturing process. The optimized model used can be replicated to other Electronic Industry and allows support of a satisfactory e-waste management.
Institutional isomorphism in collaborative, cross-cultural, project-based development work: an inquiry into the knowledge sharing behaviour of volunteers
Authors: Toner James , Martins Jorge Tiago 
Published: January 2022

Purpose
Using an institutionalist lens, this study aims to identify factors that influence the knowledge sharing behaviour of volunteers engaged in collaborative, cross-cultural and project-focussed development work.

Design/methodology/approach
Following an inductive research design, the authors conducted a thematic analysis of interviews with volunteers to explore the practicalities of knowledge sharing in the context of development aid projects and to examine contributing factors, such as personality, motivations, experience and variations in team members’ understanding of the nature and objective of projects.

Findings
Through exploring the experiences of volunteers working on cross-cultural development aid programmes, the authors identify and discuss the ways in which the preparation of volunteers and the structuring of project work is shaped by managerialist modes of thinking, with an emphasis on the creation of an environment that is conducive to sustainable knowledge sharing practices for all stakeholders involved.

Originality/value
The examination of volunteer development work tendency towards institutional isomorphism is a novel contribution intersecting the areas of knowledge sharing in the project, volunteer-led and culturally diverse environments.
Real Estate Insights Property development activities: value creation or distraction for REITs?
Authors: Wong Woei Chyuan , Ooi Joseph T.L. 
Published: January 2022

PurposeThis paper examines the evolution and impact of property development activities on REIT performance. The paper provides insights on whether REITs should venture into property development in addition to their core-business of holding income producing properties.Design/methodology/approachThis paper charts and highlights the evolution of development activities of US REITs from 1992 to 2020. The Tobin's Q of property developing REITs and non-property developing REITs are compared using univariate analysis.FindingsDevelopment activities of US REITs grew dramatically during the run up to global financial crisis (GFC) in 2008. The level of development activities has dropped since the GFC and it has not return to its pre-crisis peak. In comparison, development activities of listed property investment companies and homebuilders are less volatile over the same period. The data reveals that property developing REITs enjoy significantly higher Tobin's Q as compared to their non-developing counterparts.Practical implicationsOur graphical evidence from a market without development restriction suggests that development restriction in other REIT regimes has it value in limit REITs' excessive risk-taking tendency during a booming property market. The positive relationship between Tobin's Q and the existence of property development activity support the value creation of this business activity to REITs.Originality/valueThis paper raises overbuilding as a potential cause of the underperformance of the REIT sector during the GFC.
The paradoxes of just-in-time system: an abductive analysis of a public food manufacturing and exporting company in Thailand
Authors: Bandoophanit Thianthip , Pumprasert Siwaporn 
Published: January 2022

Purposestudy aims to investigate the implementation and impact of a just-in-time (JIT) system in a food manufacturing and exporting company in Thailand.Design/methodology/approachAt the company, the authors used an anomaly case study. The authors performed content analysis on the data collected through semi-structured interviews and direct observations to determine operational flows through customer order, production and delivery. The authors constructed a framework that helped in mapping current operations and subsequently assessing JIT’s impacts; the authors reported the best practices to the company’s owner. Based on the follow-up after a year, the authors used an abductive approach to refine the JIT theory using data from case organizations and relevant studies.FindingsThe company encountered errors and delays in international delivery owing to inadequate inputs resulting from uncertain agricultural production, delayed contact with freight forwarders, improper documentation and insufficient staffing. Besides the highly centralized system, the limitations of the JIT philosophy contributed to the issues, thereby increasing mental and physical health problems and turnover rate. Owing to these paradoxical effects, the authors extended the JIT theory. Of the study’s several recommendations, the company observed only the following: contacting the freight forwarder after the purchase order confirmation, not production completion. The authors observed increased customer satisfaction, despite the additional cost of booking containers early.Originality/valueThis research presents a balanced JIT that can minimize JIT’s impacts and resource shortage, owing to demand-supply uncertainties and sustain competitiveness.

Authors: Martínez-Catena Ana , Subirana-Malaret Montse , Subirana-Malaret Falgars 
Published: January 2022

PurposeLaw enforcement agencies and police officers' efforts were crucial to oversee the public health measures and legal regulations introduced during the Covid-19 pandemic. The study had two objectives: to examine the strategies implemented by law enforcement agencies in Catalonia (Spain) to monitor the pandemic and to explore the adverse working conditions of police officers and their personal difficulties during the state of alarm.Design/methodology/approachA total of 96 experienced police officers completed a closed-ended, anonymous online survey. In addition, complementary information was collected about the management of law enforcement agencies through open interviews. A descriptive analysis was carried out and the association between variables was explored.FindingsIn general terms, law enforcement agencies managed the uncertainty of the situation, with a focus on official information and communication channels between officers. However, many difficulties were reported by the police officers, such us inconsistency between rules, lack of preventive material or changes in work schedules. Besides, the officers' main concern, beyond the emotional impact suffered during this period, was the possibility of being infected or infecting others.Practical implicationsThe congruence between the job requirements and resources, as well as the increase of communication channels during situations of high risk are important variables to assure good job development and personal satisfaction of police officers.Originality/valueTo the knowledge of the authors, at the time of writing this paper, this is the first study in Spain to explore the management of law enforcement agencies and police officers' personal experiences during the Covid-19.

Authors: Odebode Adedayo Ayodeji , Oladokun Timothy Tunde , Ogunbayo Oyeronke Toyin , Oyedele Joseph Bamidele 
Published: January 2022

PurposeThe upward rise of the prolonged payback period and the inability of the project to generate estimated income that has been linked with the irregular rent payments has been a major problem confronting real estate investment. Given the fact that real estate investment is a risky investment venture with a highly uncertain future stream of income, this paper examines the effectiveness of rent recovery strategies in the emerging Nigeria residential real estate practice.Design/methodology/approachThe study employed an exploratory research design. The study identified the five recovery strategies adopted by the estate surveying and valuation firms in Ibadan Metropolis, Nigeria. The study adopts a purposive sampling method to select 52 registered estate firms in the study area and a questionnaire using a five-point Likert scale was used to elicit information. The data obtained were analyzed using descriptive and inferential statistics.FindingsThe result showed that the rent recovery strategies adopted by the respondents include email approach, rent reminder notice, adequate maintenance, eviction notice and dialogue approach. The perceived top-rated strategies that could influence estimated income were dialogue and rent reminder notice. Also, the findings showed the factors that influence the choice of strategy are property type, company policy and the proportion of rent to the tenant's income.Practical implicationsThe study has an implication for real estate investors and property practitioners regarding the willingness of the investors to invest in real estate investment.Originality/valueThis paper is relevant given the fact that the rental property market is prone to risk that could impede the regular streamflow of income. This serves as a need for examination of the effectiveness of adopted rent recovery strategies as it relates to real estate property management practice and investment viability.
The performativity of accounting: advancing a Posthumanist understanding
Authors: Vosselman Ed 
Published: January 2022

Purpose
The purpose of this paper is twofold. First, it seeks to articulate a framework for different conceptions of accounting’s performativity. Second, it aims to advance a Baradian posthumanist understanding of accounting’s performativity.

Design/methodology/approach
The paper traces different foundational conceptions of performativity and then articulates and substantiates different conceptions of accounting’s performativity. It advances one of these conceptions by producing a Baradian posthumanist understanding of accounting’s performativity.

Findings
Seven conceptions of performative accountings are articulated: accounting as a (counter)performative illocution; accounting as a performative perlocution; accounting as a self-fulfilling prophecy; accounting as an overflowing frame; accounting as a controlled relational agency; accounting as a mediator; and accounting as an exclusionary practice. It is argued how a posthumanist understanding of accounting as an exclusionary practice turns accounting from a world-knowing practice into a world-making practice. As such, it should be called to account.

Research limitations/implications
Posthumanist qualitative accounting research that conceives of accounting as an exclusionary practice focuses on how accounting is a material-discursive practice that intra-acts with other practices, and on how there is a power-performativity in the intra-actions that locally and temporarily (re)produces meaningful positions for subjects and objects and the boundaries between them.

Practical implications
A posthumanist understanding teaches practitioners to be attentive to and accountable for the exclusions that come with accounting or, more generally, with measurement. Accounting raises ethical concerns.

Originality/value
This paper articulates different conceptions of accounting’s performativity and makes the case for empirical non-anthropocentric examinations of accounting as an exclusionary practice.
Corporate social responsibility disclosures and reputation risk management post the banking royal commission: a study of the big four banks
Authors: Lodhia Sumit , Mitchell Nicole Angela 
Published: January 2022

Purpose
This study aims to explore the use of corporate social responsibility (CSR) disclosures by the “Big Four” Australian banks post the banking royal commission (BRC) to manage their reputational risk.

Design/methodology/approach
This paper uses a case study approach through a thematic analysis of the Big Four banks’ annual and sustainability reports and uses reputation risk management (RRM) as a conceptual lens to explore the image restoration strategies used by these banks.

Findings
The study finds that a corrective action strategy was disclosed extensively by all four banks whereby each bank outlined the actions that they were undertaking to correct the deficiencies identified by the BRC. However, the impact of these proposed actions was tampered by the fact that each bank sought to use strategies to reduce the offensiveness of their misdemeanours. It is argued that while disclosure on corrective actions and compensation is useful, an emphasis on reducing offensiveness of actions impacts the effectiveness of banks’ responses and their acceptance of full responsibility for their actions.

Research limitations/implications
This paper applies the RRM perspective to a recent reputation damaging event, thereby expanding the literature on image restoration strategies used by companies during major incidents.

Practical implications
This study provides useful insights in relation to the approaches used to manage the reputational risk arising from the BRC. It provides insights into the credibility of information disclosed post an incident and has potential implications for the assurance of such information.

Social implications
Given the critical importance of the banking industry to modern society, misconduct in this sector needs a closer examination, requiring a greater need for responsibility from its key players.

Originality/value
This study extends the applicability of the RRM perspective to a social incident and highlights that it is reputation, rather than legitimacy, that is critical when organisations in an industry face extensive public scrutiny. A thematic analysis approach adds value to the methods used for analysing CSR disclosures.
Influence of psychological safety and social presence on knowledge sharing behavior in higher education online learning environment
Authors: Catyanadika Putra Endi , Rajasekera Jay 
Published: January 2022

Purpose
The absence of physical interactions in online learning environment brings psychological influences on learning participants in interacting and sharing knowledge with others, such as ignorance of other member’s presence and insecurity to share something in online environment. The purpose of this research was to examine the knowledge sharing behavior (KSB) by online learning community members in terms of their psychological safety (PS) and social presence (SP) perceptions. In addition, this research also identified the influence of PS to promote SP and the mediation impact of SP in the relationships between PS and KSB.

Design/methodology/approach
The data were gathered through self-administered questionnaire distributed to 133 online class members at a university in Indonesia where online learning has created a new learning experience. To represent key behavioral attributes, 12 items were used to represent PS, SP and KSB. The relationships among the variables were analyzed using the structural equation modelling method.

Findings
The result showed that PS positively influenced SP and KSB. SP also brought a positive impact on promoting KSB and fully mediated the relationship between PS and KSB.

Research limitations/implications
The result may not have fully captured the reflection of the influencing factors of KSB, as this research focused only on two psychological factors, namely, PS and SP. The research may be further enriched by including additional factors and expanding the data collection to include more online learning institutions.

Practical implications
The results implied the importance of PS and SP perception to promoting KSB in online learning environments. The results highlighted an important message to universities and schools to be more concerned on students’ feeling safe personally and students’ awareness of others’ presence to maximize knowledge sharing activities in online class environment.

Originality/value
This paper revealed the importance of PS and SP to promote KSB in the higher education online learning community. To the best of the researchers’ knowledge, this is the first study to link PS and SP to KSB and identify the importance of the mediation effect of SP on the relationship between PS and KSB specifically in higher education online learning environment.
