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.

The point of departure of this book is that smart mobility will only be developed in a desired direction and fulfil societal objectives if it is steered in that direction. The market, left to itself, will most certainly not deliver on these objectives. This message has been conveyed extensively in recent literature, but this book aims to take this discussion one step further by focussing on what governance of smart mobility looks like today and in the future. In this introductory chapter, the authors provide a framework of different understandings of policy instruments, how they are selected, developed and used. After the array of policy instruments within the transport sector has been extensively discussed, the authors turn to discussing a broader understanding of policy instruments found within political science and political sociology. In doing so, this book contributes to the critical scholarship on policy instruments, while exploring the why, the how and the what of policy instruments in relation to smart mobility. The chapter closes with a brief introduction to the structure of the book as well as a description of the content of each chapter.

In this chapter, the authors will summarise the entire book and look ahead. The aim of this book has been to take the calls for governance of smart mobility one step further by analysing and discussing current and future policy instruments to govern smart mobility. The task has been carried out by discussing the why, how and what of policy instruments. So far, the policy instruments governing smart mobility to a large extent are focussed on understanding this new field of mobility, establishing relations and roles between companies and authorities, and making the field governable. What is lacking in this equation are policy instruments that establish the population as citizens with rights, voices and roles. In order to align the smart mobility transition and the transition towards a sustainable society, the authors consider the development of deliberative citizen participation an important initiative and the authors suggest it as an important field for future research.

Family events have unique significance on children as well as long-lasting impacts on them during their adulthood. A review of conceptual and theoretical literature on the subject was conducted to identify underlying trends and best practices in engaging children in the events industry. Societies are in transition from industrialised societies into risk societies and are increasingly becoming eco-socialised. Family events are integral towards developing inclusive and integrated societies and in realising Sustainable Development Goal 16 (SDG 16). Childhood is always eco-socialised, i.e. socially, economically and ecologically integrated with other forms of life. To the extent that childhood nostalgia forms the basis for future sustainable events and tourism choices. Family events are, therefore, increasingly becoming fundamental towards developing sustainability discourse. This viewpoint chapter provides conceptual and theoretical perspective on the roles and impacts of childhood research in sustainability discourse.

This paper seeks to propose a technology classification model for mobile content and service delivery platforms (MCSDPs), the core of mobile middleware technology providers' (MMTPs) value proposition.

The proposed model is grounded on existing literature and empirical research consisting of 40 in‐depth case studies with MMTPs and 102 semi‐structured interviews with top management from firms operating in the mobile content environment that already own or are interested in purchasing a MCSDP. Theoretical sampling was employed. The quality function deployment (QFD) technique was used to create the final technology classification schema.

The MCSDP technology classification model has three components: a MCSDP functional architecture, which describes platform structure in terms of its endowment of functionalities and capabilities; a MCSD classification schema, which allows the identification of a set of platform categories classified according to the range of functionalities usually possessed; and a technology classification schema consisting of a set of technology dimensions that directly influence platform efficiency and effectiveness.

The proposed model can be used for mapping existing and future MCSDP offer in terms of technological strengths and weaknesses and thus support decision‐making by platform vendors and buyers.

The main contribution is the creation of a reference framework capable of rigorously modelling the emergent phenomenon related to the rise of middleware platform providers within the mobile content environment. The paper also contributes to extending the existing QFD literature, since it demonstrates the house of quality tool's usefulness in a new context of application.

Based on the institutionalized agency theory, this paper aims to analyses the role of earnings management (EM) in mediating the relationship between ownership structure (OS) and the cost of equity capital (COE).

The authors test the above relationship by investigating a sample of 249 European non-financial listed companies during 2005-2012. The authors adopt different measures for both EM and COE and identify three main types of ownership by the majority share of the ultimate owners. Path analysis is used to explore the role of direct, mediated (i.e. EM) and total effects of OS on COE.

While OS directly affects COE, the results support the idea that an EM-mediating effect contributes to further explain this relationship in some ownership structures. Particularly European listed family-owned firms experience lower COE owing to the prevailing direct and negative effect of OS, despite the fact that both accrual and real EM mediate and have a positive effect on COE. In financial institutions-owned firms, only a direct and positive effect can be observed on COE while state-owned firms do not have a direct influence on the COE, although they do reduce real EM, which, in turn, decreases the COE in a mediated effect. Further analysis comparing the Anglo-Saxon context with Continental Europe shows more detailed results.

The study marks its entry into the international debate on the evolution in the value relevance of accounting information by arguing that the COE implications of EM depend on institutional factors such as OS and the context investigated.

The paper contributes to extant finance, accounting and corporate governance literature by providing new, robust evidence on the mediating role of EM in defining COE for different ownership types and their diverse risk-taking propensities in Continental Europe, which differs from the Anglo-Saxon context both institutionally and legally.
