We review over 10 years of research at Elsevier and various Dutch academic institutions on establishing a new format for the scientific research article. Our work rests on two main theoretical principles: the concept of modular documents, consisting of content elements that can exist and be published independently and are linked by meaningful relations, and the use of semantic data standards allowing access to heterogeneous data. We discuss the application of these concepts in five different projects: a modular format for physics articles, an XML encyclopedia in pharmacology, a semantic data integration project, a modular format for computer science proceedings papers, and our current work on research articles in cell biology.

Expectations are high for digital technologies to address sustainability related challenges. While research into such applications and the twin transformation is growing rapidly, insights in the actual daily practices of digital sustainability within organizations is lacking. This is problematic as the contributions of digital tools to sustainability goals gain shape in organizational practices. To bridge this gap, we develop a theoretical perspective on digital sustainability practices based on practice theory, with an emphasis on the concept of sociomateriality. We argue that connecting meanings related to sustainability with digital technologies is essential to establish beneficial practices. Next, we contend that the meaning of sustainability is contextspecific, which calls for a local meaning making process. Based on our theoretical exploration we develop an empirical research agenda.

From the article: "To extend the lifetime of products, an agent is connected to the product. This agent has several roles. It depends on the phase of the lifecycle what these roles will be. One of the roles in the usage or recycling phase is to negotiate for buying spare parts in case a part of the product is broken. The same agent can also decide to offer spare parts to other agents to reuse working parts of a broken product. To accomplish this idea, a marketplace for agents has to be set up, where the auctions can take place. To support this concept, blockchain technology has been used. Blockchains are a new type of technology, known from bitcoins, but there are other cases where blockchains can be used. Blockchain is known for its decentralisation, transparency and for making trustful transactions. In this paper the working of different types of blockchains will be briefly explained and determined if they can be useful for online auctions by agents. A prototype of the marketplace using blockchains has been built."

Background: In the past years, a mobile health (mHealth) app called the Dutch Talking Touch Screen Questionnaire (DTTSQ) was developed in The Netherlands. The aim of development was to enable Dutch physical therapy patients to autonomously complete a health-related questionnaire regardless of their level of literacy and digital skills. Objective: The aim of this study was to evaluate the usability (defined as the effectiveness, efficiency, and satisfaction) of the prototype of the DTTSQ for Dutch physical therapy patients with diverse levels of experience in using mobile technology. Methods: The qualitative Three-Step Test-Interview method, including both think-aloud and retrospective probing techniques, was used to gain insight into the usability of the DTTSQ. A total of 24 physical therapy patients were included. The interview data were analyzed using a thematic content analysis approach aimed at analyzing the accuracy and completeness with which participants completed the questionnaire (effectiveness), the time it took the participants to complete the questionnaire (efficiency), and the extent to which the participants were satisfied with the ease of use of the questionnaire (satisfaction). The problems encountered by the participants in this study were given a severity rating that was used to provide a rough estimate of the need for additional usability efforts. Results: All participants within this study were very satisfied with the ease of use of the DTTSQ. Overall, 9 participants stated that the usability of the app exceeded their expectations. The group of 4 average-/high-experienced participants encountered only 1 problem in total, whereas the 11 little-experienced participants encountered an average of 2 problems per person and the 9 inexperienced participants an average of 3 problems per person. A total of 13 different kind of problems were found during this study. Of these problems, 4 need to be addressed before the DTTSQ will be released because they have the potential to negatively influence future usage of the tool. The other 9 problems were less likely to influence future usage of the tool substantially. Conclusions: The usability of the DTTSQ needs to be improved before it can be released. No problems were found with satisfaction or efficiency during the usability test. The effectiveness needs to be improved by (1) making it easier to navigate through screens without the possibility of accidentally skipping one, (2) enabling the possibility to insert an answer by tapping on the text underneath a photograph instead of just touching the photograph itself, and (3) making it easier to correct wrong answers. This study shows the importance of including less skilled participants in a usability study when striving for inclusive design and the importance of measuring not just satisfaction but also efficiency and effectiveness during such studies.

In January 2008 the online photo-hosting site Flickr introduced a new section entitled The Commons. Its two key goals were to show the hidden treasures in the world’s public photography archives to the general public and to give Flickr community members the opportunity to contribute and describe these photos in order to enrich these collections. Surprisingly enough, little empirical research has been done on the actual usage of The Commons by the institutes and Flickr members. In our research we harvested a rich data sample over a 14-week period: 196,822 photos with user-generated content of 1.3 million tags, almost 130,000 comments and more than 22,000 notes. In total, 165,401 members from 188 different countries actively “did something” with the photos. This presentation will analyze this large data sample. In addition to the quantitative findings, we will discuss the qualitative findings regarding the content analysis of tags and comments.

Analyzing historical decision-related data can help support actual operational decision-making processes. Decision mining can be employed for such analysis. This paper proposes the Decision Discovery Framework (DDF) designed to develop, adapt, or select a decision discovery algorithm by outlining specific guidelines for input data usage, classifier handling, and decision model representation. This framework incorporates the use of Decision Model and Notation (DMN) for enhanced comprehensibility and normalization to simplify decision tables. The framework’s efficacy was tested by adapting the C4.5 algorithm to the DM45 algorithm. The proposed adaptations include (1) the utilization of a decision log, (2) ensure an unpruned decision tree, (3) the generation DMN, and (4) normalize decision table. Future research can focus on supporting on practitioners in modeling decisions, ensuring their decision-making is compliant, and suggesting improvements to the modeled decisions. Another future research direction is to explore the ability to process unstructured data as input for the discovery of decisions.

Elke periode kent zijn eigen revolutie en elke revolutie brengt zijn eigen organisatorische model met zich mee. We bevinden ons nu in de 4e industri¨ele revolutie, waar het internet van dingen ons verbindt met autonome embedded systemen. Deze systemen zijn actief in de virtuele ’cyber’ wereld, alsook in de echte ’fysieke’ wereld om ons heen. Deze zogenoemde ’Cyber-Fysieke’ Systemen volgen daarmee een modern organisatorisch model, namelijk zelfmanagement, en zijn dan ook in staat zelf proactieve acties te ondernemen. Dit proefschrift belicht productiesystemen vanuit het Cyber-Fysieke perspectief. De productiesystemen zijn hier herconfigureerbaar, autonoom en zeer flexibel. Dit kan enkel worden bereikt door het ontwikkelen van nieuwe methodes en het toepassen van nieuwe technologie¨en die flexibiliteit verder bevorderen. Echter, effici¨entie is ook van belang, bijvoorbeeld door productassemblage zo flexibel te maken dat het daardoor kosteneffici¨ent is om de productie van diverse producten met een lage oplage, zogenaamde high-mix, low volume producten, te automatiseren. De mogelijkheid om zo flexibel te kunnen produceren moet bereikt worden door de creatie van nieuwe methoden en middelen, waarbij nieuwe technologie¨en worden gecombineerd; een belangrijk aspect hierbij is dat dit toepasbaar getest moet worden door gebruik van simulatoren en speciaal hiervoor ontwikkelde productiesystemen. Dit onderzoek zal beginnen met het introduceren van het concept achter de bijbehorende productiemethodologie, welke Grid Manufacturing is genoemd. Grid Manufacturing wordt uitgevoerd door autonome entiteiten (agenten) die zowel de productiesystemen zelf, als de producten representeren. Producten leven dan al in de virtuele cyber wereld voordat zij daadwerkelijk zijn gebouwd, en zijn zich bewust uit welke onderdelen zij gemaakt moeten worden. De producten communiceren en overleggen met de autonome herconfigureerbare productiesystemen, de zogenaamde equiplets. Deze equiplets leveren generieke diensten aan een grote diversiteit aan producten, die hierdoor op elk moment geproduceerd kunnen worden. Het onderzoek focust hierbij specifiek op de equiplets en de technische uitdagingen om dynamisch geautomatiseerde productie mogelijk te maken. Om Grid Manufacturing mogelijk te maken is er een set van technologische uitdagingen onderzocht. De achtergrond, onderzoeksaanpak en concepten zijn dan ook de eerste drie inleidende hoofdstukken. Daarna begint het onderzoek met Hoofdstuk 4 Object Awareness. Dit hoofdstuk beschrijft een dynamische manier waarop informatie uit verschillende autonome systemen gecombineerd wordt om objecten te herkennen, lokaliseren en daarmee te kunnen manipuleren. Hoofdstuk 5 Herconfiguratie beschrijft hoe producten communiceren met de equiplets en welke achterliggende systemen ervoor zorgen dat, ondanks | Dutch Summary 232 dat het product niet bekend is met de hardware van de equiplet, deze toch in staat is acties uit te voeren. Tevens beschrijft het hoofdstuk hoe de equiplets omgaan met verschillende hardwareconfiguraties en ondanks de aanpassingen zichzelf toch kunnen besturen. De equiplet kan dan ook aangepast worden zonder dat deze opnieuw geprogrammeerd hoeft te worden. In Hoofdstuk 6 Architectuur wordt vervolgens dieper ingegaan op de bovenliggende architectuur van de equiplets. Hier worden prestaties gecombineerd met flexibiliteit, waarvoor een hybride architectuur is ontwikkeld die het grid van equiplets controleert door het gebruik van twee platformen: Multi-Agent System (MAS) en Robot Operating System (ROS). Nadat de architectuur is vastgesteld, wordt er in Hoofdstuk 7 onderzocht hoe deze veilig ingezet kan worden. Hierbij wordt een controlesysteem ingevoerd dat het systeemgedrag bepaalt, waarmee het gedrag van de equiplets transparant wordt gemaakt. Tevens zal een simulatie met input van de sensoren uit de fysieke wereld ’live’ controleren of alle bewegingen veilig uitgevoerd kunnen worden. Nadat de basisfunctionaliteit van het Grid nu compleet is, wordt in Hoofdstuk 8 Validatie en Utilisatie gekeken naar hoe Grid Manufacturing gebruikt kan worden en welke nieuwe mogelijkheden deze kan opleveren. Zo wordt er besproken hoe zowel een hi¨erarchische als een heterarchische aanpak, waar alle systemen gelijk zijn, gebruikt kan worden. Daarnaast laat het hoofdstuk o.a. aan de hand van enkele voorbeelden en simulaties zien welke effecten herconfiguratie kan hebben, en welke voordelen deze aanpak zoal kan bieden.. Het proefschrift laat zien hoe met technische middelen geautomatiseerde flexibiliteit mogelijk wordt gemaakt. Hoewel het gehele concept nog volwassen zal moeten worden, worden er enkele aspecten getoond die op de korte termijn toepasbaar zijn in de industrie. Enkele voorbeelden hiervan zijn: (1) het combineren van gegevens uit diverse (autonome) bronnen voor 6D-lokalisatie; (2) een data-gedreven systeem, de zogeheten hardware-abstractielaag, die herconfigureerbare systemen controleert en de mogelijkheid biedt om deze productiesystemen aan te passen zonder deze te hoeven herprogrammeren; en (3) het gebruik van Cyber-Fysieke systemen om de veiligheid te verhogen.

In this paper, I first discuss in some detail the current use of Learning Objects and show it to be wanting. Although their use, in principle, may offer much flexibility in creating content, in practice it will not, particularly since it does not support sufficient pedagogical flexibility. Then I offer an alternative view which, in my view, is indeed capable of fulfilling all the needs of customised learning, both the need for custom content and the need for custom pedagogies. I conclude by addressing some possible criticisms of my line of reasoning. This Chapter is a remake of Necessary Conditions for the Flexible Reuse of Educational Content.

The digital era has brought about profound changes in how music is created, distributed, and consumed, posing a need for modernizing the Dutch collective management system of music copyright to match the rapidly changing digital music industry. This study aims to identify the key stakeholders and their perceptions of the Dutch system of collective management of music copyright. Utilizing qualitative document analysis, the study examines a range of public and non-public documents, including income statements, annual reports from Collective Management Organizations (CMOs), and contracts between publishers and creators. The research is further enriched by twenty-four semi-structured interviews with key stakeholders such as composers, lyricists, music publishers, copyright lawyers, and CMO executives. The findings of the study highlight several issues like the outdated IT systems and the lack of data standardization within the system. The research also notes a contrast in organizational effectiveness: major publishers are well-organized and unified in their negotiations with Digital Service Providers (DSPs) and CMOs, effectively advocating for their rights. However, music copyright holders, despite their legal homogeneity, are either unorganized or ineffectively aligned, displaying diverse interests and varying levels of access to information, as well as differences in norms and values prioritization. The study is grounded in the economics of collective management (ECM) and makes a significant academic contribution to this field by introducing new empirical findings to ECMs core constructs and integrating theoretical perspectives. The research offers valuable insights for policymakers, industry stakeholders, and researchers, aiming to foster a more equitable music copyright management system in the digital context.
