Ervaringen met het Gebruik van Sociale Media in het Voortgezet Onderwijs

Hoewel sociale media zeer populair zijn onder jongeren, is over de effecten van het gebruik van sociale media voor onderwijsgerelateerde doeleinden in het voortgezet onderwijs tot op heden nog weinig bekend. Deze bijdrage bericht daarom over de resultaten van een verkennende studie naar het gebruik van sociale media in de bovenbouw van het voortgezet onderwijs. Daartoe is gedurende een periode van 3 maanden het sociale medium Twitter ingezet in de bovenbouwvakken Informatica en Economie voor Havo en VWO. Het doel daarbij is achtergronden, discussie, toetsmateriaal en huiswerk- en proefwerktips te verspreiden. Dit artikel bericht over de opzet, ervaringen en eerste evaluatie van dit project

User-tailored E-health services

This thesis describes a method to offer personalised healthcare. It is motivated\ud by a desire for more efficient healthcare, as population ages and care demand and costs increase. Developing and testing individually tailored health services using ICT fits in this motivation, as it leads to more adequate information provided to care receivers and caregivers, a shift in tasks from caregiver to care receiver, and most of all: health services that empower as they are personalised towards individual needs.\ud \ud In this research, a platform is realised and tested to provide user-tailored\ud e-health services. Tailored means client-specific, i.e different care receivers can consume varying care services of different vendors from the same platform. E-health services are electronic health services, or recurring health applications involving communication, mediated by ICT to bridge time and/or distance. The services in the platform apply to care situations like alarming, reminding, taking vital sign measurements, and medication management. Moreover, activity management and interaction between (in)formal caregivers and care receivers are supported. The personalisation of these services can be performed\ud by end users themselves. Hence, the e-health services are user-tailored.\ud \ud \ud To realise this platform, requirements have been elicited involving interviews\ud with end users. Desires and needs have been translated into scenarios and scenario visualisations to discuss refinement. The technical design based on this requirements engineering process, has been implemented. Then it was tested in a nursing home. Finally we researched how, given such a system in use, data can be analysed and leveraged to monitor patients over longer time, to offer decision support and to provide insight into patient behaviour.\ud \ud Results show that is possible to create a platform that enables patientspecific\ud care. The platform provides useful applications in care. These applications\ud can save time for caregivers, and increase self-management in patients. However, it requires investment in the learning process.\ud \ud In sum, the work shows that this platform successfully integrates and tailors\ud heterogeneous sensors, actuators and services from different vendor and technological origins. Moreover, the research shows how collected data can be\ud leveraged for analysis and decision support. Adequate personalisation of selected e-health services saves time, increases health situation awareness, supports interaction and furthers patient empowerment

Integrating Top-down and Bottom-up Requirements in eHealth Development:The Case of a Mobile Self-compassion Intervention for People with Newly Diagnosed Cancer

Background: Psychosocial eHealth interventions for people with cancer are promising in reducing distress; however, their results in terms of effects and adherence rates are quite mixed. Developing interventions with a solid evidence base while still ensuring adaptation to user wishes and needs is recommended to overcome this. As most models of eHealth development are based primarily on examining user experiences (so-called bottom-up requirements), it is not clear how theory and evidence (so-called top-down requirements) may best be integrated into the development process. Objective: This study aims to investigate the integration of top-down and bottom-up requirements in the co-design of eHealth applications by building on the development of a mobile self-compassion intervention for people with newly diagnosed cancer. Methods: Four co-design tasks were formulated at the start of the project and adjusted and evaluated throughout: explore bottom-up experiences, reassess top-down content, incorporate bottom-up and top-down input into concrete features and design, and synergize bottom-up and top-down input into the intervention context. These tasks were executed iteratively during a series of co-design sessions over the course of 2 years, in which 15 people with cancer and 7 nurses (recruited from 2 hospitals) participated. On the basis of the sessions, a list of requirements, a final intervention design, and an evaluation of the co-design process and tasks were yielded. Results: The final list of requirements included intervention content (eg, major topics of compassionate mind training such as psychoeducation about 3 emotion systems and main issues that people with cancer encounter after diagnosis such as regulating information consumption), navigation, visual design, implementation strategies, and persuasive elements. The final intervention, Compas-Y, is a mobile self-compassion training comprising 6 training modules and several supportive functionalities such as a mood tracker and persuasive elements such as push notifications. The 4 co-design tasks helped overcome challenges in the development process such as dealing with conflicting top-down and bottom-up requirements and enabled the integration of all main requirements into the design. Conclusions: This study addressed the necessary integration of top-down and bottom-up requirements into eHealth development by examining a preliminary model of 4 co-design tasks. Broader considerations regarding the design of a mobile intervention based on traditional intervention formats and merging the scientific disciplines of psychology and design research are discussed

Context, design and implementation of a control system for ring resonator-based optical beam forming networks

The goalis to develop and implement a control system for ring resonator-based Optical Beam Forming Networks (OBFNs). Beam shaping and beam steering, together called beamforming, is needed when processing radio-frequency signals from phased array antennas. This can be achieved in the optical domain, by tuning an OBFN. The tuning of such a network is the task of a control system. That system is the topic of research in this assignment. It enables thermo-optical tuning of ring resonator based OBFNs. In this thesis, the context, design and implementation of the control system are studied. Measurements are described to show the correct working of the implemented prototype. The control system may be used in the future in an airborne application. It may form part of a system that provides services such as radio, television, and internet access to en route aircraft. It is a challenge to make this possible. The control system consists of a controller and an interface to operate it. The controller has hardware and software aspects. The hardware is a modular set of components that can easily be extended when necessary. The software in the controller operates the hardware and provides the means for tuning OBFNs. A graphical interface is provided on a PC to operate the controller. This can easily be adapted to future needs. Two prototypes for the control system have been delivered in this assignment. The first prototype met the most important requirements but was not very easy to operate. The second implemented also met the more advanced requirements, enabled tuning of larger OBFNs, and was provided with an easy-to-use Java interface. The system has been used extensively in the TE lab and also at the Dutch Aerospace Laboratory (NLR). In the future, the system can be extended to provide angle and azimuth steering (to steer the beam to a certain point) and tracking and tracing functionalities (to find and keep focussed on a source)
