In this paper, we investigate the efficiency of ray queries on the CPU in the context of path tracing, where ray distributions are mostly random. We show that existing schemes that exploit data locality to improve ray tracing efficiency fail to do so beyond the first diffuse bounce, and analyze the cause for this. We then present an alternative scheme inspired by the work of Pharr et al. in which we improve data locality by using a data-centric breadth-first approach. We show that our scheme improves on state-of-the-art performance for ray distributions in a path tracer.

Internationalization and global citizenship are increasingly becoming the emerging focus of higher education worldwide as universities seek to incorporate global learning in their policies, curricula and strategies. Global engagement, international collaborations, strategic alliances and operations are all on the increase with the aim of delivering future-proof graduates with a global mindset and inter-cultural competences. Additionally, it can be noted that hybridity in education is acutely present through the digitalisation of delivery modes as well as the introduction of new mobility formats, such as faculty-led study abroad programmes and transnational education at branch campuses. So not only do we see more activity, but also more delivery modes of international education. While both digital delivery and new mobility structures transcend traditional boundaries of space and locality, it is precisely this point that can pose serious challenges to the success of international education. Both involve a “relocation” of education; however, when the physical locality, where the students and lecturers are rooted in certain value and beliefs systems, is not considered, the risk is that the educational experience remains one-sided despite the multidimensional context of which it should be a part. Locality is the key to successful and meaningful internationalisation. After presenting the case that locality is of paramount importance, this chapter will outline the conceptual model of intercultureality, which allows education programs to foster and nurture intercultural competence development of students in their own unique landscape from the ground up. Using the metaphor of a landscape, intercultureality provides tools to create an intercultural reality by utilising the unique hybrid of the physical locality, the disciplinary context, the dynamics of the (virtual) classroom as well as the infrastructures in place. The underlying idea is that programmes and institutions can grow any kind of landscape that works for their context, building on the soil of their own previously defined intercultural competence goals. This soil will be enriched by means of five features: the formal curriculum, the pedagogy, the student experience, the informal curriculum, and the organisational and strategic frameworks. The model is further elaborated upon and illustrated with examples of practices of The Hague University of Applied Sciences (THUAS), where the authors work.

In recent years, disasters are increasing in numbers, location, intensity and impact; they have become more unpredictable due to climate change, raising questions about disaster preparedness and management. Attempts by government entities at limiting the impact of disasters are insufficient, awareness and action are urgently needed at the citizen level to create awareness, develop capacity, facilitate implementation of management plans and to coordinate local action at times of uncertainty. We need a cultural and behavioral change to create resilient citizens, communities, and environments. To develop and maintain new ways of thinking has to start by anticipating long-term bottom-up resilience and collaborations. We propose to develop a serious game on a physical tabletop that allows individuals and communities to work with a moderator and to simulate disasters and individual and collective action in their locality, to mimic real-world scenarios using game mechanics and to train trainers. Two companies–Stratsims, a company specialized in game development, and Society College, an organization that aims to strengthen society, combine their expertise as changemakers. They work with Professor Carola Hein (TU Delft), who has developed knowledge about questions of disaster and rebuilding worldwide and the conditions for meaningful and long-term disaster preparedness. The partners have already reached out to relevant communities in Amsterdam and the Netherlands, including UNUN, a network of Ukrainians in the Netherlands. Jaap de Goede, an experienced strategy simulation expert, will lead outreach activities in diverse communities to train trainers and moderate workshops. This game will be highly relevant for citizens to help grow awareness and capacity for preparing for and coping with disasters in a bottom-up fashion. The toolkit will be available for download and printing open access, and for purchase. The team will offer training and facilitate workshops working with local communities to initiate bottom-up change in policy making and planning.
