DBpedia extracts structured information from Wikipedia, interlinks it with other knowledge bases and freely publishes the results on the web using Linked Data and SPARQL. However, the DBpedia release process is heavyweight and releases are sometimes based on several months old data. DBpedia‐Live solves this problem by providing a live synchronization method based on the update stream of Wikipedia. This paper seeks to address these issues.

Wikipedia provides DBpedia with a continuous stream of updates, i.e. a stream of articles, which were recently updated. DBpedia‐Live processes that stream on the fly to obtain RDF data and stores the extracted data back to DBpedia. DBpedia‐Live publishes the newly added/deleted triples in files, in order to enable synchronization between the DBpedia endpoint and other DBpedia mirrors.

During the realization of DBpedia‐Live the authors learned that it is crucial to process Wikipedia updates in a priority queue. Recently‐updated Wikipedia articles should have the highest priority, over mapping‐changes and unmodified pages. An overall finding is that there are plenty of opportunities arising from the emerging Web of Data for librarians.

DBpedia had and has a great effect on the Web of Data and became a crystallization point for it. Many companies and researchers use DBpedia and its public services to improve their applications and research approaches. The DBpedia‐Live framework improves DBpedia further by timely synchronizing it with Wikipedia, which is relevant for many use cases requiring up‐to‐date information.

The new DBpedia‐Live framework adds new features to the old DBpedia‐Live framework, e.g. abstract extraction, ontology changes, and changesets publication.

This paper aims to investigate the interaction between capital requirements and pricing constraints as measures for insurance regulation.

In a theoretical model framework, the author derives the insurer’s shareholder-value-maximizing response to capital regulation, price regulation and the unregulated strategy as a benchmark; all three strategies are presented in an analytical form.

The paper demonstrates that risk-based capital requirements exhibit an efficiency advantage over price regulation and allow for lower premiums. Moreover, the analysis identifies situations in which price floors make insurance more expensive, but have no positive impact on the safety level.

The comparison between capital regulation and price floors provides policymakers with a methodology to evaluate which regulatory tool is more appropriate. Also, the article discusses that maximum discount rates for European life insurers could be ineffective when the new regulatory framework Solvency II is in place.

In all, the article obtains analytical and informative results with relevant implications for insurance regulation.

Many observers believe that industry experience of entrepreneurs drives successful new entrepreneurial firms. However, whenever it comes to disruptive digital ventures such as Financial Technologies (Fintechs), the picture may be different due to the cross-industry nature of digital firms. The purpose of this study is to disentangle the impacts of finance, banking and information technology (IT) experiences of founders on performance of European Fintechs around venture capital (VC) investment.

Based on a data set of 105 Fintechs from European countries, including UK, which are involved in 201 VC rounds between 2006 and 2019, the authors adopt a Bayesian quantile approach to link founders’ experience with two performance measures that identify market success (return on sales) and investment outcome (return on equity).

The findings indicate that finance and IT-specific experiences seem to matter more often than banking experience and that the extent of their impact depends on level and metric of performance. More specifically, Fintechs in Europe and UK are more able to achieve market success with both finance and IT experiences of their founders, but that does not necessarily transform into higher returns for investors.

This study provides new evidence that not all aspects of industry experience matter for digital ventures, as they must fit to a certain firm, cycle and industry. For Fintech, as the name says, finance and IT experiences matter.

Despite the innovation and performance of venture capital (VC)-backed firms receiving extensive attention, how and under what conditions VC influences innovation and performance remains unclear. The present paper draws on organizational learning (OL) theory to examine the moderating effect of syndication on backed firms.

Drawing on a literature review that connects OL and innovation to the performance of VC-backed firms, this study examines the effects of OL on innovation and firm performance among these firms by questioning the moderating effect of VC syndication. A sample of 78 VC-backed firms was used to test the robustness of the proposed model and causal relationships through the use of partial least squares structural equation modeling (PLS-SEM).

The empirical evidence demonstrates that the intervention of venture capitalists can not only stimulate innovation, but also have a significantly positive effect on firm performance. Furthermore, the evidence reveals that syndication of VC investment supports backed firms in improving the firms' performance and generating innovation from acquired knowledge.

To the best of the authors' knowledge, this study is the first in North Africa that focuses on the moderating effects of venture capital syndication on the relationships between OL, innovation and firm performance.

An understanding of the role of decision-making has been emphasised since the seminal works on human information processing and professional judgements by accountants. The interest in these topics has been reignited by the increasing digitisation of the financial reporting and auditing processes. Whilst the behavioural research on accounting is well-established, the application of seminal works in cognitive psychology and behavioural finance is lacking, especially from recent research endeavours. The purpose of this paper is to provide a synthesis of theories relating to accounting behavioural research by evaluating them against the theories of cognitive psychology.

Using theory synthesis, this research draws seemingly isolated strands of research into a coherent framework, underpinned by cognitive psychology.

Evidence from accounting and auditing behavioural research is largely consistent with the psychology and finance research on cognitive limitations and errors. There remains a lacuna in accounting behavioural research on debiasing techniques. Such research, if underpinned by a single, cohesive theoretical framework, is likely to have practical relevance.

The current research has theoretical implications for the accounting decision-making and uncertainty research. Areas for future research, based on identified gaps in the current accounting behavioural research, are also proposed.

During December 2012, Jorge Paulo Lemann, a co-founder and partner at 3G, proposed to Warren Buffett that 3G and Berkshire Hathaway acquire H. J. Heinz Company. Lemann and Buffett, who had known each other for years, jointly decided that the Heinz turnaround had been successful and that there was significant potential for continued global growth. 3G informed Heinz CEO William Johnson that it and Berkshire Hathaway were interested in jointly acquiring his company. Johnson then presented the investors' offer of $70.00 per share of outstanding common stock to the Heinz board.

After much discussion, the Heinz board and its advisors informed 3G that without better financial terms they would not continue to discuss the possibility of an acquisition. Two days later, 3G and Berkshire Hathaway returned with a revised proposal of $72.50 per share, for a total transaction value of $28 billion (including Heinz's outstanding debt).

Following a forty-day “go-shop” period, Heinz, 3G, and Berkshire Hathaway agreed to sign the deal. But was this, in fact, a fair deal? And what might be the future consequences for shareholders, management, employees, and citizens of Pittsburgh, the location of the company's headquarters? Last, what was the role of activist investors in bringing Heinz to this deal stage?

After reading and analyzing the case, students will be able to:

• Understand the influence of investment bankers on M&A transactions

• Consider synergies that drive M&A

• Consider the role of activist investors in corporate strategic decision-making

• Understand the impact of M&A on key corporate stakeholders

• Apply core valuation techniques to support M&A valuation

This study aims to investigate the impact of venture capital (VC) involvement on investment efficiency (IE) and its potential action mechanisms from the perspective of financial resource allocation.

Using data of Chinese firms between 2008 and 2020, and the propensity score matching–difference in differences method, the authors investigate the relationship between VC and IE.

The results show that VC involvement significantly promotes IE, and the effect exhibits an inverted U-shape dynamic over time. The authors find two mechanisms through which VC promotes IE: alleviating financing constraints and improving corporate governance. Supplementary tests indicate that VC institutions with high reputations play a significant role in enhancing IE; the promotion effect is more pronounced for firms in non-high-tech industries, firms facing higher industrial competition and firms located in areas with better property rights protection systems.

This study provides several original contributions. First, based on principal–agent and financing constraint theories, this study enhances the literature by revealing how VC drives the IE of newly public firms in China. Second, to the best of the authors’ knowledge, this is the first attempt to identify the mechanisms between VC and IE; Third, from an empirical perspective, besides discussing the average and dynamic effect of VC on IE, this study also explores the impact of the interaction between VC and market competition and property rights protection on IE.
