Nature in cities serves a multitude of purposes, one of which is that it provides citizens opportunities to recover from stressful daily urban life. Such stress recovering effects of nature can be experienced through urban green, which in urban planning and design contexts can be divided into large natural areas - urban green space - and small scale elements in urban streets: the urban greenscape. The current study aims at finding the extent to which various small scale natural elements in residential streets and their possible configurations influence citizens' preferences for those streets. The research was conducted through an online survey in four cities in the Netherlands (n = 4,956). It used stated choice methods in a virtual environment street design. The method yielded high quality data, indicating that the use of virtual environments and imagery is suitable for stated choice research in the built environment. The results show that especially trees very strongly influence preference, indicating they deserve more attention and space in cities. Grass, which is typically favored by local governments, and vertical green have the smallest effects in residential streets. Furthermore, the concept of greenscape intensity is introduced as the intensities of both the element and the configuration were found to be highly relevant. The results clearly show that the higher either of these intensities, the more likely a respondent will prefer the greenscape design. Furthermore, low intensity on the one can be compensated by high intensity on the other. With these results, urban design professionals and local governments can better trade-off the different aspects of costs versus positive effects of urban greenscape designs.

This paper provides a comparative study between problems causedby cybersickness with users in virtual environments, and the studies on theinfluence of the optical aspects of the image via its levels of contrasts in thequality of the user experience in virtual environments. This article was organized in two parts, the first consists of surveying the results obtained in eachresearch and the second has the objective of crossing these data and verifyingthe level of relationship between research on cybersickness and studies on theinfluence of optical aspects quality of the user experience. The results indicaterelevant connection with the results of studies on cybersickness. With that, weconclude that in future research researchers can produce much more relevantresults in the solution of persistent problems from the negative experience withvirtual devices

Seven college lecturers and two senior support staff were interviewed during 2021 about their experiences teaching in hybrid virtual classrooms (HVC). These technology-rich learning environments allow teachers to simultaneously teach students who are in class (on campus) and students who are joining remotely (online). There were two reasons for this choice: first, ongoing experimentation from innovative teaching staff who were already using this format before the COVID-19 pandemic; secondly, as a possible solution to restrictions on classroom size imposed by the pandemic. Challenges lecturers faced include adjusting teaching practice and lesson delivery to serve students in the class and those online equally; engaging and linking the different student groups in structured and natural interactions; overcoming technical challenges regarding audio and visual equipment; suitably configuring teaching spaces and having sufficient pedagogical and technical support to manage this complex process. A set of practical suggestions is provided. Lecturers should make reasoned choices when teaching in this format since it requires continued experimentation and practice to enhance the teaching and learning opportunities. When external factors such as classroom size restrictions are the driving force, the specific type of synchronous learning activities should be carefully considered. The structure and approach to lessons needs to be rethought to optimise the affordances of the hybrid virtual and connected classroom. The complexity of using these formats, and the additional time needed to do it properly, should not be underestimated. These findings are consistent with previous literature on this subject. An ongoing dialogue with faculty, support staff and especially students should be an integral part of any further implementation in this format.

This paper describes a project to explore the possibilities of virtual worlds in educating Green IT. In the project a virtual world has been created with various assignments which are meant to create awareness on sustainability aspects of IT. The world (and the assignments) will be incorporated in a course for first-year IT students. In order to measure the effects of the course, a questionnaire has been developed which can be used before and after the course to measure the attitude towards green IT.

Abstract Background Visuospatial neglect (VSN) is a cognitive disorder after stroke in which patients fail to consciously process and interact with contralesional stimuli. Visual Scanning Training (VST) is the recommended treatment in clinical guidelines. At the moment, several mixed reality versions of Visual Scanning Training (VST) are being developed. The aim of this study was to explore the opinions of end-users (i.e., therapists) on the use of Virtual Reality (VR) and Augmented Reality (AR) in VSN treatment. Methods Therapists played one VR and two AR Serious Games, and subsequently flled out a questionnaire on User Experience, Usability, and Implementation. Results Sixteen therapists (psychologists, occupational, speech, and physiotherapists) played the games, thirteen of them evaluated the games. Therapists saw great potential in all three games, yet there was room for improvement on the level of usability, especially for tailoring the games to the patient’s needs. Therapists’ opinions were comparable between VR and AR Serious Games. For implementation, therapists stressed the urgency of clear guidelines and instructions. Discussion Even though VR/AR technology is promising for VSN treatment, there is no one-size-fts-all applicability. It may thus be crucial to move towards a plethora of training environments rather than a single standardized mixed reality neglect treatment. Conclusion As therapists see the potential value of mixed reality, it remains important to investigate the efcacy of AR and VR training tools.

Virtual care centres (VCCs) are novel wards of hospitals and facilitate the provision of remote monitoring and home-based patient care by virtual care nurses. Whereas since the COVID-19 pandemic VCCs have rapidly emerged, there is a lack of insight in virtual care nurses’ work and the associated work load. Therefore, the aim of this study was to identify the nursing activities performed in Virtual Care Centers (VCCs) and assess nurses’ perceived workload associated with these activities. A multicentre descriptive, observational cross-sectional study was performed.

This chapter revisits the concept of internationalisation at home in light of the COVID pandemic and also of experiences and ongoing discourses on internationalisation. These include how internationalisation at home relates to diversity, inclusion and decolonisation of curricula. It discusses how the COVID pandemic has led to increased attention to internationalisation at home but also that confusion about terminology and the desire for physical mobility to be available to students may lead us to return to pre-COVID practices, in which internationalisation is mainly understood as mobility for a small minority of students and internationalisation of the home curriculum is a poor second best. A component of this chapter is how Virtual Exchange and Collaborative Online International Learning (COIL) have moved into the spotlight during the pandemic but were already in focus areas well before. This will be illustrated by some recent developments in internationalisation at home, mainly from non-Anglophone, European and particularly Dutch perspectives.

Virtual training systems provide highly realistic training environments for police. This study assesses whether a pain stimulus can enhance the training responses and sense of the presence of these systems. Police officers (n = 219) were trained either with or without a pain stimulus in a 2D simulator (VirTra V-300) and a 3D virtual reality (VR) system. Two (training simulator) × 2 (pain stimulus) ANOVAs revealed a significant interaction effect for perceived stress (p =.010, ηp2 =.039). Post-hoc pairwise comparisons showed that VR provokes significantly higher levels of perceived stress compared to VirTra when no pain stimulus is used (p =.009). With a pain stimulus, VirTra training provokes significantly higher levels of perceived stress compared to VirTra training without a pain stimulus (p <.001). Sense of presence was unaffected by the pain stimulus in both training systems. Our results indicate that VR training appears sufficiently realistic without adding a pain stimulus. Practitioner summary: Virtual police training benefits from highly realistic training environments. This study found that adding a pain stimulus heightened perceived stress in a 2D simulator, whereas it influenced neither training responses nor sense of presence in a VR system. VR training appears sufficiently realistic without adding a pain stimulus.
