This paper aims to expand the emerging literature on COVID-19 and the financial markets by searching for a relationship between the uncertainty of the first phase of the COVID-19 pandemic experienced through social media and the extreme volatility of the Italian stock market.

The authors analyze the relationship between social media and stock market trends during the first phase of the COVID-19 pandemic through the lens of social theory and Baudrillard's simulacra and hyperreality theory. The authors conducted the data analysis in two phases: the emotional and Granger correlation analysis by using the KPI6 software to analyze 3,275,588 tweets for the predominant emotion on each day and observe its relationship with the stock market.

The research results show a significant Granger causality relation between tweets on a particular day and the closing price of the FTSE MIB during the first phase of the COVID-19 epidemic. The results highlight a strong relationship between social media hyperreality and the real world. The study confirms the role of social media in predicting stock market volatility.

The findings have theoretical and practical implications as they reveal the relevance of social media in our society and its relationship with businesses and economies. In an emergency, social media, as an expression of users' feelings and emotions, can generate a state of hyperreality that is strong correlated with reality. Since social media allows users to publish and share messages without any filter and mediation, the hyperreality generated is affected by highly subjective elements.

This research is different from the previous ones on the same topic because unlike previous studies, conducted under normal or simulated scenarios, this study is focused on the first phase of an unpredictable and unforeseen emergency event: the COVID-19 pandemic. This research adopts a multidisciplinary approach and integrates previous studies on the economic and financial effects generated by social media by applying well-known theories to a new and unexplored context. The study reveals the significant impact generated by social media on stock markets during a global pandemic.

This paper aims to provide a helpful tool for those who plan to implement blockchain-based solutions for the governance of the electronic medical record (EMR) in health-care settings. The goals are to identify each type of stakeholders involved in these projects and to clarify the relevance, to achieve success, of their readiness, intended as availability and ability to adopt blockchain.

The chosen methodology is a multiple case study on three initiatives that used blockchain to manage EMRs. This study relied on multiple sources of evidence. The primary data consisted of two rounds of semi-structured interviews with different informants. This study followed a grounded theory approach and performed within- and cross-case analyses.

This study identified the types of stakeholders – nodes and not-nodes – of the network and how their readiness level affects the implementation of blockchain-based projects applied to EMR. The nodes (e.g. patients and doctors) are pivotal in making the network working once this has been constructed. Out of the four readiness dimensions suggested by literature, motivational readiness, has the higher impact. Not-nodes stakeholders play a pivotal role in the project’s pre-implementation phase. For them, structural readiness is the dimension with the higher relevance.

To the best of the authors’ knowledge, it is the first time that a paper analyses the differences between nodes and not-nodes stakeholders of the blockchain network, in terms not only of type but also of readiness. Identifying the readiness level to implement successful projects is a fundamental step that has never been analysed in the health field.

This study aims to explore how firms can enhance their innovation processes by effectively utilizing external knowledge and employing digital technologies. Specifically, it emphasizes the role of absorptive capacity (ACAP) in external knowledge acquisition and assimilation (potential ACAP), as well as transformation and exploitation (realized ACAP), highlighting the necessity of equipping firms with digital technologies to support ACAP activities.

To achieve the research purpose, we conducted a structured literature review of academic papers sourced from Scopus-Elsevier.

The key findings encompass the identification of common digital technologies supporting ACAP and explore how these technologies contribute to knowledge acquisition, assimilation, transformation and exploitation. The main results show that social media and online communities are the most studied technologies in relation to ACAP activities. Research predominantly centres on potential ACAP – with acquisition activity more studied than assimilation – rather than realized ACAP – with only social media and online communities demonstrating full support for transformation and exploitation activities.

This research represents a pioneering joint study of ACAP and digital technologies, advancing understanding beyond organizational perspectives and expanding open innovation literature by integrating ACAP role in technology collaborations. A call for qualitative investigations into the relationship between digital technologies and ACAP emerged.

The findings offer valuable guidance to innovation managers, aiding them in selecting appropriate digital technologies to strengthen ACAP activities.

This work’s uniqueness lies in bridging the gaps between open innovation, ACAP and digital technologies, which are often studied in isolation.

The study investigates the use of early forms of environmental accounting in the implementation of environmental strategies in the Grand Duchy of Tuscany between the 16th and 17th centuries.

The study adopts the Foucauldian concept of raison d’État to shed light on the ways in which environmental accounting practices were used by Tuscan Grand Dukes to form a detailed knowledge of the territory to be governed and act accordingly.

Financial and non-financial information relating to environmental issues enabled the Grand Dukes to “visualise” the territory to be managed as an enclosed disciplinary space whereby the conduct of people living therein could be decisively influenced. Accounting practices as a tool for the implementation of environmental strategies did not merely aim to protect the environment but were a means to reinforce the power of the State.

The paper can inform future works that investigate the ways in which environmental policies and accounting are used to pursue far-reaching governmental goals. It encourages scholars to examine further the origins of environmental accounting and its early forms.

The study documents how environmental strategies and the related use of accounting can have a significant influence on how individuals are allowed to conduct themselves. It also shows that environmental accounting practices can be an important tool in a State’s machinery of power.

The study offers a novel perspective on the use of environmental accounting information as a tool in the exercise of State power. It explores explicitly the interrelations between accounting, sustainability and power. It also adds new evidence to historical research that has engaged with early forms of environmental accounting.

This paper introduces the second part of a AAAJ special issue on accounting, accountability and management during the COVID-19 emergency. The authors analyse the themes that emerge from the second part of the special issue, which allows us to identify the diverse accounting and accountability practices across different geographical and organisational contexts. The authors also provide an overall picture of the contributions of the special issue, with insights into avenues of future research.

Building on the first part of the AAAJ special issue, the paper draws together and identifies additional emerging themes related to research into the COVID-19 pandemic and how it impacts accounting, accountability and management practices. The authors reflect on the contributions of the special issue to the interdisciplinary accounting research project.

The authors identify two macro-themes and outline their contributions to the accounting literature. The first deals with the changes and dangers of accounting and accountability practices during the pandemic. The second considers accountability practices in a broader sense, including reporting, disclosure and rhetorical practices in the management of COVID-19.

The paper shows the pervasive role of accounting and accountability in the unprecedented and indiscriminate health crisis of COVID-19. It highlights the important role of special issues in producing timely research that responds to unfolding events.

This paper contributes to current debates on the roles of accounting and accountability during COVID-19 by drawing together the themes of the special issue and identifying future interdisciplinary accounting research on the pandemic's aftermath.
