Educational institutions in higher education encounter different thresholds when scaling up to institution-wide learning analytics. This doctoral research focuses on designing a model of capabilities that institutions need to develop in order to remove these barriers and thus maximise the benefits of learning analytics.

Longitudinal criminological studies greatly improved our understanding of the longitudinal patterns of criminality. These studies, however, focused almost exclusively on traditional types of offending and it is therefore unclear whether results are generalizable to online types of offending. This study attempted to identify the developmental trajectories of active hackers who perform web defacements. The data for this study consisted of 2,745,311 attacks performed by 66,553 hackers and reported to Zone-H between January 2010 and March 2017. Semi-parametric group-based trajectory models were used to distinguish six different groups of hackers based on the timing and frequency of their defacements. The results demonstrated some common relationships to traditional types of crime, as a small population of defacers accounted for the majority of defacements against websites. Additionally, the methods and targeting practices of defacers differed based on the frequency with which they performed defacements generally.

In hoofdstuk 1 wordt ingegaan op de aanleiding voor de literatuurstudie, de keuze voor OWO en doel, onderzoeksvragen en verantwoording van de literatuurstudie. Hoofdstuk 2 schetst een beeld van gebiedsgebonden politiewerk en gaat in op de rol en samenstelling van basisteams (onderzoeksvragen 1 en 2). Hoofdstuk 3 gaat in op het begrip digitalisering, beschrijft de digitalisering van gebiedsgebonden politiewerk en inventariseert knelpunten (onderzoeksvraag 3). In hoofdstuk 4 wordt het begrip ‘digitale handelingsbekwaamheid’ verkent, de betekenis van digitale handelingsbekwaamheid voor het GGP wordt in kaart gebracht en in verband gebracht met leerstijlen binnen organisaties. Ook worden de knelpunten ten aanzien van digitale handelingsbekwaamheid geïnventariseerd (onderzoeksvraag 4). In hoofdstuk 5 worden relevante theorieën over het de gebruik en de acceptatie van digitale technologieën, veranderingsbereid en leertheorieën besproken (onderzoeksvraag 5). In hoofdstuk 6 ten slotte wordt het conceptueel model gepresenteerd en verantwoord. Het conceptueel model dient als basis voor het op te stellen Programma van Eisen.

In the literature about web survey methodology, significant e orts have been made to understand the role of time-invariant factors (e.g. gender, education and marital status) in (non-)response mechanisms. Time-invariant factors alone, however, cannot account for most variations in (non-)responses, especially fluctuations of response rates over time. This observation inspires us to investigate the counterpart of time-invariant factors, namely time-varying factors and the potential role they play in web survey (non-)response. Specifically, we study the effects of time, weather and societal trends (derived from Google Trends data) on the daily (non-)response patterns of the 2016 and 2017 Dutch Health Surveys. Using discrete-time survival analysis, we find, among others, that weekends, holidays, pleasant weather, disease outbreaks and terrorism salience are associated with fewer responses. Furthermore, we show that using these variables alone achieves satisfactory prediction accuracy of both daily and cumulative response rates when the trained model is applied to future unseen data. This approach has the further benefit of requiring only non-personal contextual information and thus involving no privacy issues. We discuss the implications of the study for survey research and data collection.

Patients with cardiovascular risk factors can reduce their risk of cardiovascular disease by increasing their physical activity and their physical fitness. According to the guidelines for cardiovascular risk management, health professionals should encourage their patients to engage in physical activity. In this paper, we provide insight regarding the systematic development of a Web-based intervention for both health professionals and patients with cardiovascular risk factors using the development method Intervention Mapping. The different steps of Intervention Mapping are described to open up the “black box” of Web-based intervention development and to support future Web-based intervention development.

At present, persons with dementia and their family caregivers in the Netherlands are not adequately supported to modify their dwellings to match their personal needs. To facilitate aging-in-place for persons with dementia, a website was designed. The website was designed with persons with dementia and their spouses. In consultation sessions existing websites were discussed. Based on this discussion, a demonstration website was created and then discussed with and judged by the participants. Visits to the website were monitored using Google Analytics.

Objective This scoping review aims to identify complex health interventions (CHI’s) to prevent early childhood caries (ECC), explore the level of complexity of the identified CHI’s, and explore the details of their development, evaluation, and implementation. Introduction Many interventions to prevent ECC have multiple interacting components and can be seen as CHI’s. Recent reviews on these interventions have found inconclusive effects, which may be due to differences in the development, evaluation, and implementation of CHI’s. Inclusion criteria This scoping review will consider clinical trials reporting CHI’s to prevent ECC that starts during pregnancy or in the first year of life. Studies in the English language will be included regardless of the country of origin, sociocultural setting, or context. Methods This review will follow the Joanna Briggs Institute methodology for scoping reviews. An initial search of PubMed identified keywords and Medical Subject Headings terms. A second search of PubMed, Embase, Clarivate Analytics/Web of Science Core Collection, ClinicalTrials.gov, and the Wiley/Cochrane Library will follow. Two independent reviewers will perform title and abstract screening, retrieve and review full-text studies, and extract data. The reference lists of all included sources will be screened for additional CHI’s or relevant publications about a specific CHI. Data charting will be utilised based on study characteristics and intervention complexity. A 39-item instrument will be used to explore the details in the description of the CHI’s development, evaluation, and implementation. The results will be presented in tables, visual outputs, and a narrative summary in response to the review questions. Discussion The proposed review will generate evidence which may provide a direction for the future design of studies on CHI’s to prevent ECC and more complete information for those who want to adopt successful interventions to prevent ECC.

Dit artikel gaat over de waarde van Twitter als een nieuwsbron voor journalisten. Het artikel poogt de theoretische discussie in de literatuur over de mogelijkheden en de waarde van Twitter een empirische grondslag te geven. In die discussie speelt het artikel van Alfred Hermida, 'Twittering the News', een centrale rol. In dit artikel wordt berichtgeving via Twitter rondom de crash van Turkish Airline TK 1951 op 25 februari 2009 op Schiphol tot uitgangspunt genomen. De analyse, gebaseerd op een beoordeling van de tweets op verschillende variabelen, beschrijft de nieuwswaarde van Twitter en laat zien hoe het nieuws via Twitter zich ontwikkelt. Ten tweede wordt een vergelijking gemaakt met de crash van Ryanair in Schotland op 23 december en de crash van American Airlines op 22 december op het vliegveld van Kingston op Jamaica. Deze drie gevallen zijn als ongeval goed vergelijkbaar en op alle drie de gevallen is eenzelfde analyse toegepast, waarbij duidelijk verschillen zijn aan te wijzen in de rol van Twitter als nieuwsbron. Aan het eind van het artikel komt de vraag aan de orde of 'wisdom of the crowds', dat is het filteren van het nieuws door de gebruikers zelf, een rol speelt? Daarvoor wordt een vergelijking gemaakt tussen de tweets rondom de Schiphol crash en de verslaggeving via Coveritlive, waarin ook gebruik werd gemaakt van de input van Twitter en commentaar van de gebruikers, en waarbij een journalist de rol van moderator had.

Today’s internet has become like Deleuze’s societies of control, media scholars argue. The network’s invisible infrastructure, with near global reach, has amplified hierarchies, and is owned, exploited and surveilled by internet, advertising, and data-analytics companies, and by state security institutions. With the digital data produced by the often banal and quotidian activities of millions of internet users – or dividuals – a monopoly of a handful of Tech Giants accumulate massive amounts of wealth, and influence. The world wide web, various media scholars contend, has degenerated to a serpent’s coil. This article argues that the rhizomatic Wood Wide Web provides a basis from which to rethink today’s debate on the present and future of the internet, and challenges a predominant understanding of the societies control. Beneath our feet and beyond our perception, a subterranean meshwork of trees, mushrooms and fungi forms an ecology of trans-species solidarity, singularities, and creative, collaborative interactivity that could carry us outside the entrapments of the supposed totality of the societies of control.What can the World Wide Web learn from the Wood Wide Web?

In this paper we discuss the general approach and choices we made in developing a prototype of a social media monitor. The main goal of the museum monitor is to offer museum professionals and researchers better insight in the effects of their own social media usage and compare this with other actors in the cultural heritage sector. It gives researchers the opportunity to consider communication within the sector as whole. In the research project “Museum Compass” we have developed a prototype of a social media monitor, which contains data of current and historic online activities on Facebook, Twitter, YouTube, Foursquare and Flickr of all registered Dutch museums. We discuss – mostly in a practical sense – our approach for developing the monitor and give a few examples as a result of its usage.
