The building stock accounts for a significant portion of worldwide energy consumption and greenhouse gas emissions. While the majority of the existing building stock has poor energy performance, deep renovation efforts are stymied by a wide range of human, technological, organisational and external environment factors across the value chain. A key challenge is integrating appropriate human resources, materials, fabrication, information and automation systems and knowledge management in a proper manner to achieve the required outcomes and meet the relevant regulatory standards, while satisfying a wide range of stakeholders with differing, often conflicting, motivations. RINNO is a Horizon 2020 project that aims to deliver a set of processes that, when working together, provide a system, repository, marketplace and enabling workflow process for managing deep renovation projects from inception to implementation. This paper presents a roadmap for an open renovation platform for managing and delivering deep renovation projects for residential buildings based on seven design principles. We illustrate a preliminary stepwise framework for applying the platform across the full-lifecycle of a deep renovation project. Based on this work, RINNO will develop a new open renovation software platform that will be implemented and evaluated at four pilot sites with varying construction, regulatory, market and climate contexts.

The continued proliferation of information technology in all aspects of our lives fosters benefits but also generates risks to individuals’ privacy. In emerging contexts, such as government surveillance technologies, there is a dearth of research investigating the positive and negative drivers of citizens’ acceptance. This is an important gap given the importance of citizen acceptance to the success of these technologies and the need to balance potentially wide-reaching benefits with any dilution of citizen privacy. We conduct a longitudinal examination of the competing influences of positive beliefs and privacy concerns on citizens’ acceptance of a COVID-19 national contact tracing mobile application among 405 Irish citizens. Combining privacy calculus theory with social exchange theory, we find that citizens’ initial acceptance is shaped by their perceptions of health benefits and social influence, with reciprocity exhibiting a sustained influence on acceptance over time and privacy concerns demonstrating a negative, albeit weak influence on willingness to rely on the application. The study offers important empirical and theoretical implications for the privacy literature in the government surveillance, location-based services, and mobile health application contexts, as well as practical implications for governments and developers introducing applications that rely on mass acceptance and reciprocal information disclosure.

Blockchain can potentially disrupt business processes across many industries. Despite substantial hype, blockchain adoption still remains quite low. Research suggests that the success and adoption of a new technology depends on whether it is deemed legitimate by key stakeholders. This is extremely important in the context of blockchain given the controversial reputation that some derivative innovations, such as Bitcoin, have gained over time. This chapter explores and compares how four types of business actors which play a prominent role in the blockchain ecosystem—the media, IT, financial services and consulting firms—attempted to build legitimacy around blockchain and Bitcoin on Twitter. Findings suggest that the messaging strategies employed by firms for blockchain and Bitcoin differ. While no dominant firm-level messaging strategies to build legitimacy around Bitcoin emerge, firms primarily employ three micro-level legitimation strategies to build legitimacy around blockchain. More specifically, communication strategies around blockchain focus on publishing the involvement of influential actors (pragmatic legitimacy), highlighting blockchain ongoing developments and associated market responses (cognitive legitimacy), and presenting technological advancements directly or indirectly related to blockchain (cognitive legitimacy). The findings illustrate how the key actors engage in the blockchain and Bitcoin legitimation discourse to help interpret this complex innovation and mobilise the market to adopt.

This data article describes a dataset of data breaches in US listed firms over a ten-year period. Data breaches represent major events that pose serious challenges to organisations. The number of incidents has been on the increase over the last decade and this has attracted the interest of the media, consumers and regulators. While there is a well-established literature on cybersecurity in Computer Science and Information Systems journals, studies exploring the economic and business impacts of data breaches represent a relatively recent phenomenon. There is a nascent but fast-growing literature in accounting, finance and economics that focuses on the financial impacts of data breaches and this dataset provides a useful resource for future studies in this space. By providing data on the company identifier, the type of breach, the dates of breach disclosure, and relates these dates to the company's fiscal year, the dataset can be merged quickly with existing accounting and finance datasets. The dataset includes data on 506 incidents over a ten-year period thereby enabling cross-sectional and longitudinal analyses.

This study investigates the effect of news media coverage on trading activity in, and the liquidity of, target firms’ shares around acquisition announcements. We use the number of articles published in four of the UK's main newspapers as a proxy for media coverage. Our dataset includes 350 UK domestic acquisition deals between 1996 and 2014. The results of our analysis suggest that media coverage is positively associated with target firms’ trading activity and stock liquidity. This is consistent with the media playing a key role in mitigating information asymmetry in the financial markets. This study contributes to the literature on stock market reactions to acquisition announcements by investigating the effect of media coverage on trading activity and stock liquidity beyond the price run-up, and by providing additional insights into the UK market which traditionally attracts less attention than the US market.

As signals of internal control weaknesses, cyber security incidents can represent significant risk factors to the quality of financial reporting. We empirically assess the audit quality implications of data breaches for a large sample of US firms. Using a difference-in-difference approach based on a matched sample of breached and non-breached firms, we find no evidence that cyber-security incidents result in a decline in audit quality. Instead, we observe positive shifts in four widely-used proxies for audit quality. We document that breached firms (i) experience a decrease in abnormal accruals, (ii) are less likely to report small profits or small earnings increases, (iii) are more likely to be issued a going concern report, and (iv) are less likely to restate their financial statements in the two years following a breach. Our results indicate that auditors effectively offset increases in audit risk through additional substantive testing and audit effort. Our evidence supports the view that auditors have increased their audit risk awareness and put in place adequate procedures to deal with the consequences of cyber-security incidents.

Social media is widely used by accounting firms to achieve a variety of business objectives and is a key enabler of non-market strategies. Socio-political involvement (SPI) involves firms taking positions on issues that lack societal consensus, have low information rationality, evolving viewpoints and issue salience, with no clear performance outcomes for firms. SPI may result in firms alienating stakeholders with opposing views, resulting in no or adverse performance outcomes. Accounting firms traditionally may not engage with such issues due to the associated reputational risk. Further, research suggests firm size is one of the most prominent firm-level antecedents of socio-political engagement. As the empirical context for this paper, we choose the Brexit referendum, a significant historical but divisive event with contested social norms. This paper explores the engagement of accounting firms on Twitter with the #Brexit discourse from the referendum announcement to one month after the vote. The objectives of the study are to understand the nature of non-market socio-political engagement by accounting firms in the #Brexit discourse on Twitter, and explore the differences between accounting firms of different size in this context. Our findings suggest that accounting firms engaged in the #Brexit Twitter discourse through a variety of non-market socio-political engagement activities, and that smaller firms tended to engage more than larger firms, most likely reflecting the ideological inclination of firm management. The engagement of accounting firms in socio-political discourse extends our understanding of how accounting firms of all sizes use social media and supports critical accounting and institutional perspectives.

Over 2.8 million people die each year from being overweight or obese, a largely preventable disease. Social media has fundamentally changed the way we communicate, collaborate, consume, and create content. The ease with which content can be shared has resulted in a rapid increase in the number of individuals or organisations that seek to influence opinion and the volume of content that they generate. The nutrition and diet domain is not immune to this phenomenon. Unfortunately, from a public health perspective, many of these `influencers’ may be poorly qualified in order to provide nutritional or dietary guidance, and advice given may be without accepted scientific evidence and contrary to public health policy. In this preliminary study, we analyse the `healthy diet’ discourse on Twitter. While using a multi-component analytical approach, we analyse more than 1.2 million English language tweets over a 16-month period in order to identify and characterise the influential actors and discover topics of interest in the discourse. Our analysis suggests that the discourse is dominated by non-health professionals. There is widespread use of bots that pollute the discourse and seek to create a false equivalence on the efficacy of a particular nutritional strategy or diet. Topic modelling suggests a significant focus on diet, nutrition, exercise, weight, disease, and quality of life. Public health policy makers and professional nutritionists need to consider what interventions can be taken in order to counteract the influence of non-professional and bad actors on social media.

Together, social media and crowdsourcing can help entrepreneurs to attract external finance and early-stage customers. This paper investigates the characteristics and discourse of an issue-centered public on Twitter organized around the hashtag #crowdfunding through the lens of social network theory. Using a dataset of 2,732,144 tweets published during a calendar year, we use exploratory data analysis to generate insights and hypotheses on who the users in the #crowdfunding network are, what they share, and how they are connected to each other. In order to do so, we adopt a range of descriptive, content, network analytics techniques. The results suggest that platforms, crowdfunders, and other actors who derive income from the crowdfunding economy play a key role in creating the network. Furthermore, latent ties (strangers) play a direct role in disseminating information, investing, and sending signals to platforms that further raises campaign prominence. We also introduce a new type of social tie, the “computer as a social actor”, previously unaddressed in entrepreneurial network literature, which play a role in sending signals to both platforms and networks. Our results suggest that homophily is a key driver for creating network sub-communities built around specific platforms, project types, domains, or geography.

Mobilization theory posits that social media gives a voice to non-traditional actors in socio-political discourse. This study uses network analytics to understand the underlying structure of the Brexit discourse and whether the main sub-networks identify new publics and influencers in political participation, and specifically industry stakeholders. Content analytics and peak detection analysis are used to provide greater explanatory values to the organizing themes for these sub-networks. Our findings suggest that the Brexit discourse on Twitter can be largely explained by calculated publics organized around the two campaigns and political parties. Ad hoc communities were identified based on (i) the media, (ii) geo-location, and (iii) the US presidential election. Other than the media, significant sub-communities did not form around industry as whole or around individual sectors or leaders. Participation by business accounts in the Twitter discourse had limited impact.

Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) adoption typically require radical changes in an organisation’s IT operations and have widespread implications that go beyond simple cost savings. This chapter presents a practical framework for estimating the Return on Investment (ROI) for IaaS and PaaS from the customer perspective. The proposed framework aims to overcome the main limitations of commonly-used Total Cost of Ownership (TCO) calculators by including both tangible and intangible costs and benefits to provide a more comprehensive ROI estimation. The application of the framework is illustrated using a real-life case study of infrastructure migration.

High performance computing (HPC) is widely recognized as a key enabling technology for advancing scientific progress, industrial competitiveness, national and regional security, and the quality of human life. Notwithstanding this contribution, the large upfront investment and technical expertise required has limited the adoption of HPC to large organizations, government bodies, and third level institutions. Recent advances in cloud computing and telecommunications have the potential to overcome the historical issues associated with HPC through increased flexibility and efficiency, and reduced capital and operational expenditure. This study seeks to advance the literature on technology adoption and assimilation in the under-examined HPC context through a mixed methods approach. Firstly, the determinants of cloud computing adoption for HPC are examined through a survey of 121 HPC decision makers worldwide. Secondly, a modified Delphi method was conducted with 13 experts to identify and prioritize critical issues in the adoption of cloud computing for HPC. Results from the quantitative phase suggest that only organizational and human factors significantly influence cloud computing adoption decisions for HPC. While security was not identified as a significant influencer in adoption decisions, qualitative research findings suggest that data privacy and security issues are an immediate and long-term concern.

We provide new insights into the business lending decisions of institutional investors in online credit markets by benchmarking their lending performance against that of retail investors.We find superior performance for loans financed by institutional investors, although large sized retail investor groups achieve equivalent performance. Lending decisions of institutional investors are not default risk minimising, and we quantify lending inefficiencies. From a platform perspective, we show that (i) the platform-administered loan allocation process is not biased in favour of institutional investors, (ii) institutional participation in the retail marketplace is not a distorting factor in loan performance, and (iii) the platform’s move to a fixed rate system had detrimental effects on loan outcomes for institutional investors. The superior loan performance achieved by institutional investors is confined to the auction period, when institutional investors had autonomy over setting interest rates.

This study investigates the impact of cyber-security incidents on audit fees. Using a sample of 5,687 firms, we find that (i) breached firms are charged 12% higher audit fees, and (ii) firms operating in the same industry of a breached firm are charged 5% higher fees. Finally, using a difference-in-difference regression on a propensity score matched sample, we provide evidence suggesting that auditors do not revise their audit risk assessment following a breach. Overall, these results suggest that the increase in audit fees in the year of a breach is only temporary, and that auditors include cyber-security risk in their audit risk assessment even before an incident occurs. Higher cyber-security risk is ultimately reflected in higher audit fees paid by auditees.

Cloud computing promises traditional enterprises and independent software vendors a myriad of advantages over on-premise installations including cost, operational and organizational efficiencies. The decision to migrate software configured for on-premise delivery to the cloud requires careful technical consideration and planning. In this chapter, we discuss the impact of right-scaling on the cost modelling for migration decision making and price setting of software for commercial resale. An integrated process is presented for measuring total cost of ownership, taking in to account IaaS/PaaS resource consumption based on forecast SaaS usage levels. The process is illustrated with a real world case study.

Data breaches are not only on the increase but firms struggle to detect, defend and respond to such breaches. A data breach opens a period of crisis for the affected firm, generates complex information, and requires providing information to a variety of stakeholders in a timely and proper manner. This article reports one of the first studies on the impact of social media exposure by affected firms on stock price reaction to a data breach announcement. Using an event study methodology on a sample of 87 data breaches from 73 US publicly-traded firms from 2011 to 2014, we find that use of social media exposure at the time of a data breach exacerbates the negative stock price to the announcement. Interestingly, we find that this negative association is contingent on traditional media visibility; the effect is positive for low-visibility companies. Based on our results, we posit that there is a need for a contingency model for social media communication during firm crises and such a model should be based at least on firm size, visibility and the type of crisis.

To answer this question, this study draws on Twitter data and filters it using the linguistic identifiers, ‘#Gaeilge’ and the word ‘Gaeilge’ (Irish language). Tweets with these identifiers are conceptually considered as formulations of agentic practice with respect to language (Sabatier, P. [2007]. Theories of the Policy Process. Boulder, CO: Westview Press). Individuals who use the #Gaeilge identifier in particular are viewed within this study as micro-implementers. Their communications provide partial insight into agentic activities within the Twittersphere specifically, related to and about the Irish language. To explore this data, peak, network, content and sentiment analyses were conducted. The study’s findings illustrate that there are a number of influential hubs in this network. They are in the main micro-level individuals as opposed to macro-level or governmental institutions promoting the Irish language. This paper demonstrates the potential for in-depth research into agentic practices of minority linguistic communities within Twitter, and outlines the limitations of a computational approach in conducting such research.
