This paper investigates the impact of investor attention on the COVID-19 concept stocks in China's stock market from the perspectives of the macroeconomy, the stock market and the COVID-19 pandemic.

On the basis of controlling the time effects and individual fixed effects, this paper studies the impact of investor attention on the COVID-19 concept stocks in China's stock market through a set of fixed effect panel data models. Among them, investor attention focuses on macroeconomy, stock market and the COVID-19 pandemic, respectively, while stock indicators cover return, volatility and turnover. In addition, this paper also examines the heterogeneity influence of investor attention on the COVID-19 concept stocks from the perspective of time and stock classification.

Findings indicate that the attention to macroeconomy does not have a statistically significant effect on the return, unlike the attention to stock market and COVID-19 incident. Three types of investor attention have significant positive effects on the volatility and turnover rate. During the outbreak of the domestic epidemic, the impact of investor attention was significantly higher than that during the outbreak of the epidemic overseas. A finer-grained analysis shows that the attention to stock market has significantly increased the return of preventive type and treatment type stocks, while diagnostic-related stocks have been most affected by the attention to COVID-19 incident.

The major limitation of this work is the construction of investor attention. Although Baidu index is widely used, investor attention can be assessed more accurately based on more unstructured data. In addition, the effect of the COVID-19 can also be investigated in a longer time domain. Further research can be combined with the dynamics of the COVID-19 pandemic to more comprehensively evaluate its impact on the stock market.

The research proves that investor attention plays an important role in stock pricing and provides empirical evidence on the behavioral foundations of the conceptual sector of the stock market under uncertainty. It also has practical implications for regulators and investors interested in conducting accurate asset allocation and risk assessment.

China has established 14 marine economic development demonstration zones in 2018, which has become an important step in exploring the high-quality development of the marine economy. The paper statistically analyzes the documents related to the field of marine economy and special economic zones (SEZs) and strives to find out the hot spots, intersections and related development contexts of the two in the research direction, so as to provide some ideas for later research.

By taking the bibliographic information data of “Marine Economy” and “Special Economic Zone” in the Web of Science database as a sample, the paper applies the Citespace bibliometric tool to analyze the evolution of disciplinary distribution, research country, author collaboration and research hotspot trends in the two fields.

It can be found from the paper results that the current research on marine economy and SEZs involves the intersection of many disciplines. China and the United States are the leaders in this field. However, there is more extensive cooperation between authors from different countries, but the cooperation depth needs to be strengthened. At the same time, compared with the terrestrial economy, the trend of its research hotspots is lagging to a certain extent. Moreover, there is still no systematic and professional research paradigm on marine economy.

At present, there are a few research studies on marine economic development demonstration areas or marine SEZs, and related bibliographical references are incomplete, which leads to insufficient samples, and bibliometric methods cannot fully reveal the general research rules and development trends in this field.

The research on the marine economic development demonstration area is still in its infancy. The paper jointly analyzes the literature in the two fields of marine economy and SEZs, aims to find the intersection and related research hotspots of the two, and provides references for the future research of marine development demonstration areas, which is of certain practical significance.

This paper aims to analyze Public Companies Accounting Oversight Board (PCAOB) inspection reports on audit reports of those inspected accounting firms in Brazil, Russia, India and China (BRIC). In meeting the requirements of the Sarbanes-Oxley Act, the PCAOB conducts inspections on audit reports of firms listed on the New York Stock Exchange.

The reports include those submitted by both the US audit parent firms and their secondary firms located outside the USA. In each PCAOB report, it unravels the nature of audit deficiencies. The focus is on Big Four because they play a dominant role in the marketplace and issuers’ market capitalization. All the seven-year deficiencies are documented since publications of the reports from 2004 to 2012.

Of the 37 reports, 19 (51 per cent) were issued relating to audits conducted by the Big Four. Out of these 19 reports, 10 (53 per cent) contain inspection criticism. These include audit quality and common recurring audit deficiencies.

This paper is based solely on those inspection reports published by the PCAOB.

The findings have significant implications to audit firms and the audit profession on improving audit quality, firms’ internal control and reports.

No known prior research paper is available on the ramifications of the PCAOB’s inspection reports relating to BRIC.

The purpose of this paper is to examine the factors related to the use of the balanced scorecard (BSC) by private companies. Specifically, the authors examine how foreign ownership, focus on a global market beyond the local company’s geographic region and other sophisticated management accounting practices (MAPs) (activity-based costing, just-in-time and total quality management) are related to the use of the BSC.

The paper takes a contingency theoretic perspective. The data in this study is based on responses to a survey questionnaire that was mailed to 300 non-listed private companies in Singapore. A total of 135 responses were received, but 23 were incomplete, and thus, rendered unusable. Therefore, the final sample for the study is 112 private companies yielding a 37.3 per cent response rate that is considered high for survey research.

The authors find significant associations between the use of BSC and foreign ownership, focus on a global market and other sophisticated MAPs. The authors find that foreign ownership and a global market focus are significantly and consistently related to the extent to which the BSC is used across seven different management control purposes. The authors also find some evidence of associations between other sophisticated MAPs and the extent to which the BSC is used for management control purposes.

Private companies can use the BSC to better manage risks and use it for purposes such as communicating strategy and objectives, setting targets, evaluating performance, rewarding employees and managers, motivating employees and managers, controlling performance and coordinating across activities, departments and/or functional areas. The study has limitations such as the model is limited and excludes the effects of other significant contingency factors such as organisational culture. It may be appropriate to interview organisational participants to learn more about how their national and organisational culture affects the decision to use the BSC.

The findings fill a critical void in the literature by providing new evidence on the determinants of the use of the BSC by private companies.

For human resource (HR) managers, the harmful outcomes of employees’ ruminations about external crises, such as a pandemic, represent important, timely concerns. This research postulates that employees’ perceptions of pandemic threats might diminish the extent to which they engage in change-oriented voluntarism at work. This negative connection may be attenuated by employees’ access to two personal (work-related self-efficacy and organization-based self-esteem) and two relational (goal congruence and interpersonal harmony) resources.

The theoretical predictions are tested with survey data collected among employees who work in a banking organization in Portugal.

Persistent negative thoughts about a pandemic undermine discretionary efforts to alter and enhance the organizational status quo, but this detrimental effect is mitigated when employees (1) feel confident about their work-related abilities, (2) have a positive self-image about their organizational functioning, (3) share a common mindset with coworkers with respect to work goals and (4) maintain harmonious relationships with coworkers.

This study pinpoints several ways HR managers can reduce the danger that employees’ worries about life-threatening crises may lead to complacent responses that, somewhat paradoxically, might undermine their ability to alleviate the suffered hardships.

The findings contribute to research on the impact of external crisis situations on organizations by providing an explanation of why employees may avoid productive, disruptive work activities, contingent on their access to complementary resources.

The purpose of this paper is to propose a new dynamic margin setting method for margin buying in China and evaluate the validity of its performance with the current margin system adopted by stock exchanges in extreme episodes.

This paper adopts the dynamic conceptual model of Huang et al. (2012) (which is based on Figlewski (1984)) but incorporates Markov chain to describe the data generation process of stock price changes. By applying the model to margin buying contracts for the period of March 16, 2018, to May 2, 2018 (baseline study) and June 15, 2015, to July 27, 2015 (robustness test), the model’s superiority to the current margin system adopted by stock exchanges is also tested.

The paper has several important findings. First, the margins derived by this system vary with market conditions, rising (declining) when stock prices go down (up), and are generally lower than the requirements imposed by stock exchanges. Second, this margin system induces lower overall percentage of costs than that adopted by stock exchanges. Third, parameter estimation plays an important role on shaping empirical results.

The primary limitation of this paper lies in the fact that it does not solve the issue of determining optimal parameters of the Markov chain model. On the implication of findings, policy-makers and regulators on supervising margin buying activities may need a tune-up on the current margin system which features static margin requirements. Dynamic margins that incorporate market factors are virtually useful to balance the trade-off between liquidity and prudence.

To the best of the authors’ knowledge, this study is the first of its kind to develop a dynamic margin setting method for margin buying in China, aiming to balance the trade-off between liquidity and prudence. It not only takes into account the uniqueness of Chinese markets but also allows for time variations in both initial and maintenance margins.

The evolution of Knowledge-Management (KM)-related literature has highlighted that Knowledge Management Systems (KMSs) have undergone massive changes in collaborative environments. Information-Systems-enabled KM seems to be the necessary response to the recent challenges posed by globalisation and technology dynamics to both large companies (LCs) and small and medium enterprises (SMEs).

This paper provides a systematic review about KMSs to offer an analytical overview of their role in supporting innovative forms of knowledge translation occurring in collaborative relationships. A sample of 129 papers was selected and analysed according to three perspectives: unit of analysis (LCs, SMEs), phases of the KM process (adoption, translation) and topic area (KM Practices, KM Tools, KMSs).

The findings highlight five literature gaps: (1) the role of KM practices supporting knowledge translation; (2) the impact of the alignment among KM practices, firm's complexity, dimension and culture on KM process; (3) the effect of KM tools on knowledge translation; (4) the variety of KMSs exploited in both LCs and SMEs; and (5) the alignment between organisational structure and information systems in KM context. Accordingly, 13 research questions were formulated.

The proposed research questions define a formal research agenda that could steer further research efforts about the KMS topic for improving the body of knowledge in the KM field. Scientific literature is currently lacking a contribution assessing the role of KMSs in supporting innovative forms of knowledge translation that occur in collaborative relationships.

The purpose of this paper is to investigate the interaction between mandatory disclosures and voluntary disclosures of banks and the information content of corporate disclosures on firm performance.

Based on the US-listed banks from 2007 to 2015, this paper examines the interplay among the fair-value measurement, corporate governance disclosure and voluntary social responsibility disclosure. In addition, the paper examines the extent of such disclosure of mandatory items (fair-value measurement) versus voluntary items (corporate governance and social responsibility issues) on banks’ performance in terms of their return on equity and return on asset.

This paper finds that banks with a higher social responsibility disclosure score and stronger corporate governance tend to have lower percentages of Level 3 fair-value assets. Banks with a higher Level 3 fair-value asset disclosure have a lower financial performance.

This paper provides evidence of the interplay of various corporate disclosures by banks and implies that banks use fair-value measurements to disguise their poor performance. The findings provide insights for the policymakers, investors and regulators to assess banks’ disclosure.

This paper extends the study of banks’ fair-value measurements and is the first study to examine the interaction between voluntary and mandatory disclosures. This study sheds lights on the theories of performativity, agency and stakeholder by demonstrating the information contents of corporate disclosures on firm performance.

This study aims to draw upon boundary the crossing theory to examine the transition of casino hotel guests’ revisit intentions from casino social media sites to casino properties, with the influence of the motivation–opportunity–ability model.

Under a quantitative approach, 20 casinos that operated official social media sites were selected, with a quota sampling method designed to assign 20 respondents for each casino. A structural model was used to explore the hypothesized relationships.

The results illustrate that ability and opportunity are crucial in enhancing social media revisit intention. They also reveal that casino and destination revisit intention can be boosted with increased social media revisit intention.

This study provides a fresh look into the relation across the boundary between the virtual and physical environment and illustrates a means by which casinos can be camouflaged as leisure and entertainment venues to strengthen their competitiveness in attracting tourists through social media.

This study offers new evidence for the linkage between online and offline behaviors with respect to how social media could transit into tangible travel propensity.

This study seeks to unravel the relationship between employees' passion for work and their engagement in problem-focused voice behavior by identifying a mediating role of their efforts to promote work-related goal congruence and a moderating role of their perceptions of pandemic threats to the organization.

The research hypotheses were tested with quantitative data collected through a survey instrument administered among 158 employees in a large Portuguese-based organization that operates in the food sector, in the midst of the coronavirus disease 2019 (COVID-19) pandemic. The Process macro was applied to assess the moderated mediation dynamic that underpins the proposed theoretical framework.

Employees' positive work-related energy enhances their propensity to speak up about organizational failures because they seek to find common ground with their colleagues with respect to the organization's goals and future. The mediating role of such congruence-promoting efforts is particularly prominent to the extent that employees dwell on the threats that a pandemic holds for their organization.

The study pinpoints how HR managers can leverage a negative situation—employees who cannot keep the harmful organizational impact of a life-threatening virus out of their minds—into productive outcomes, by channeling positive work energy, derived from their passion for work, toward activities that bring organizational problems into the open.

This study adds to HR management research by unveiling how employees' attempts to gather their coworkers around a shared work-related mindset can explain how their passion might spur reports of problem areas, as well as explicating how perceived pandemic-related threats activate this process.
