Although governments are investing heavily in big data analytics, reports show mixed results in terms of performance. Whilst big data analytics capability provided a valuable lens in business and seems useful for the public sector, there is little knowledge of its relationship with governmental performance. This study aims to explain how big data analytics capability led to governmental performance. Using a survey research methodology, an integrated conceptual model is proposed highlighting a comprehensive set of big data analytics resources influencing governmental performance. The conceptual model was developed based on prior literature. Using a PLS-SEM approach, the results strongly support the posited hypotheses. Big data analytics capability has a strong impact on governmental efficiency, effectiveness, and fairness. The findings of this paper confirmed the imperative role of big data analytics capability in governmental performance in the public sector, which earlier studies found in the private sector. This study also validated measures of governmental performance.

The focus of the present study is the extent to which an internship or study abroad contributes to students’ development of international competencies, such as interpersonal and intercultural competencies, foreign language skills, and international academic and professional competencies.
In Nederlandse scholen zijn jaarlijks vele tienduizenden praktijkbegeleiders (mentoren) van leraren in opleiding actief. De meeste mentoren doen dit begeleidingswerk naast hun hoofdtaak als leraar van leerlingen. Een ervaren leraar is niet per definitie ook een goede mentor. Om mentoren te ondersteunen in hun belangrijke werk verzorgen veel scholen, vaak in samenwerking met lerarenopleidingen, trainingen in begeleidingsvaardigheden. Voor Frank Crasborn en Paul Hennissen vormde hun ervaring als lerarenopleider en trainer van honderden mentoren de inspiratiebron voor het opzetten van onderzoek. Dit leidde tot een onderzoeksproject van acht deelstudies, waarin zowel naar gedragsaspecten als naar gerelateerde cognitieve aspecten van begeleidingsgedrag van mentoren werd gekeken. De resultaten van het onderzoek leidden tot een bijdrage aan de ordening van begrippen en concepten die gebruikt worden om begeleidingsgedrag van begeleiders in gesprekken met leraren in opleiding in kaart te brengen en te analyseren; een gedetailleerd beeld van begeleidingsgedrag in authentieke begeleidingsgesprekken en de manier waarop leraren in opleiding dit gedrag percipiëren; het blootleggen van cognities van mentoren, gekoppeld aan begeleidingsgedrag in gesprekken met leraren in opleiding; meer inzicht in de reikwijdte van training op de ontwikkeling van het doen en denken van begeleiders in begeleidingsgesprekken; een instrument voor reflectie op begeleidingsgedrag van mentoren; aanwijzingen voor verbetering van trainingen voor mentoren.

The integration of renewable energy resources, controllable devices and energy storage into electricity distribution grids requires Decentralized Energy Management to ensure a stable distribution process. This demands the full integration of information and communication technology into the control of distribution grids. Supervisory Control and Data Acquisition (SCADA) is used to communicate measurements and commands between individual components and the control server. In the future this control is especially needed at medium voltage and probably also at the low voltage. This leads to an increased connectivity and thereby makes the system more vulnerable to cyber-attacks. According to the research agenda NCSRA III, the energy domain is becoming a prime target for cyber-attacks, e.g., abusing control protocol vulnerabilities. Detection of such attacks in SCADA networks is challenging when only relying on existing network Intrusion Detection Systems (IDSs). Although these systems were designed specifically for SCADA, they do not necessarily detect malicious control commands sent in legitimate format. However, analyzing each command in the context of the physical system has the potential to reveal certain inconsistencies. We propose to use dedicated intrusion detection mechanisms, which are fundamentally different from existing techniques used in the Internet. Up to now distribution grids are monitored and controlled centrally, whereby measurements are taken at field stations and send to the control room, which then issues commands back to actuators. In future smart grids, communication with and remote control of field stations is required. Attackers, who gain access to the corresponding communication links to substations can intercept and even exchange commands, which would not be detected by central security mechanisms. We argue that centralized SCADA systems should be enhanced by a distributed intrusion-detection approach to meet the new security challenges. Recently, as a first step a process-aware monitoring approach has been proposed as an additional layer that can be applied directly at Remote Terminal Units (RTUs). However, this allows purely local consistency checks. Instead, we propose a distributed and integrated approach for process-aware monitoring, which includes knowledge about the grid topology and measurements from neighboring RTUs to detect malicious incoming commands. The proposed approach requires a near real-time model of the relevant physical process, direct and secure communication between adjacent RTUs, and synchronized sensor measurements in trustable real-time, labeled with accurate global time-stamps. We investigate, to which extend the grid topology can be integrated into the IDS, while maintaining near real-time performance. Based on topology information and efficient solving of power flow equation we aim to detect e.g. non-consistent voltage drops or the occurrence of over/under-voltage and -current. By this, centrally requested switching commands and transformer tap change commands can be checked on consistency and safety based on the current state of the physical system. The developed concepts are not only relevant to increase the security of the distribution grids but are also crucial to deal with future developments like e.g. the safe integration of microgrids in the distribution networks or the operation of decentralized heat or biogas networks.
