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.

Welcome to the fourth special issue of the Pervasive Labour Union zine, Urgent Publishing Debris. In May 2019, the Making Public: Urgent Publishing Conference took place. Among others, it asked the following questions:-"How to realize sustainable, high-quality alternatives within this domain of post-digital publishing?"-"How can designers, developers, artists, writers and publishers intervene in the public debate and counter misinformation in a meaningful and relevant way?"-"What are new publishing strategies for our current media landscape?"-"How to design for urgency without succumbing to an accelerated hype cycle?"The presentations, debates and conversations have all been officially documented in blogposts on the Institute of Network Cultures website, videos and pictures. But what about the notes, the pictures, the recordings and the tweets of the conference's visitors? What do they have to tell us about how each person experienced the conference? This special issue aims to provide new readings of the event by creating remixes of the official archival sources with the 'unofficial' debris circulating around it.In order to facilitate the navigation between articles, making connections visible where they might have only been implicit, the editors have decided to define eleven overarching topics (Social/Community, Activism, Post-truth, New forms, Authorship/Makers, Speed, Positioning, Locality, Relationality, Authoritarianism, Parasite). Each of the topics was attributed a colour and the source material is highlighted accordingly.Furthermore, each remix has a dispersed editors' note, wherein each editor reflects in more detail on the program, how it connects to the conference's topic and how it might answer any of the aforementioned questions.

The increased importance attached by policy-makers to the anticipated developmental effects of tourism in developing countries has been insufficiently examined by academic researchers, particularly in the context of the contribution of small firms in urban areas. This deficiency is addressed by providing a review of existing research followed by an analysis of interviews with 90 tourism business located within and outside the townships of Langa and Imizamo Yethu, Cape Town, South Africa. The findings reveal tensions between the different actors involved in township tourism. While the involvement of small, locally owned, businesses is beneficial, it is limited by conflicts of interest, lack of trust, limited social networks and little attachment to the township locality. The discussion highlights the complexity of tourism's role in economic development, which has significant implications for local policy-makers.

Purpose: This conceptual paper explores the problems associated with trying to address culture as one of the key aspects in effective workplace strategies. Design/methodology/approach: This paper critically addresses the relationship between workplace strategies and the behavioural components of locality. It reviews the role that the concept of culture has, so far, played in trying to predict these behavioural consequences as part of (literature discussing) efforts to design appropriate workplace strategies. Findings: The discussion reveals the need to further address this relation through dedicated research. What is more, it is argued that there is a clear need to focus explicitly on work patterns, and how these can be accounted for in workplace strategies, instead of continuing to focus on the concept of culture as a predictor for successfulness. It is argued that the latter does not allow for practical application, whereas the former could help us to better understand and predict the effectiveness of specific workplace strategies in specific (local) circumstances. Practical implications: The outcome of the discussion suggests that organisations consisting of multiple locations could benefit from explicitly accounting for (local) work patterns in setting up workplace strategies for the organisation as a whole. Originality/value: This paper reveals a relevant research gap in current literature on workplace strategies and suggests a shift in focus from culture to work patterns as one of the key aspects to address.

This paper presents the results of the research project ‘Going Eco, Going Dutch’ (2015- 2017), which investigated the production, design and branding of fashion textiles made from locally produced hemp fibers in the Netherlands. For fashion labels and designers it is often difficult to scrutinize the production of textile fabrics manufactured in non-European countries due to physical distance and, often, non-transparency. At the same time, many designers and established fashion brands increasingly search for sustainable textiles that could be recycled or upcycled after being used by consumers. For the project ‘Going Eco, Going Dutch’, local textile manufacturers and fashion brands closely collaborated to explore how to develop fashionable textiles made from locally produced hemp – from the very first fiber to the final branding of the fashion product. In addition to the technical insights on the production of hemp, this paper will present and highlight the importance of the visual identity of the textiles, which was created by using Dutch traditional crafts – suggesting that this should be understood in terms of Kristine Harper’s ‘aesthetic sustainability’ (2017) as an essential design strategy. In addition, this paper will reflect on the importance of storytelling by focusing on locality and transparency, and on creating an emotional bond and connection between producer, product and consumer. This paper will argue that this form of ‘emotional durability’ (Chapman, 2005, 2009) is essential to both design and branding strategies. Moreover, this paper will critically reflect on the performance of Dutchness – Dutch national identity – through these locally produced fibers, textiles and fashion products.

Fans constitute a very special kind of audience. They have been marginalized, ridiculed and stigmatized, yet at the same time they seem to represent the vanguard of new relationships with and within the media. ‘Participatory culture’ has become the new normative standard. Concepts derived from early fan studies, such as transmedial storytelling and co-creation, are now the standard fare of journalism and marketing text books alike. Indeed, usage of the word fan has become ubiquitous. The Ashgate Research Companion to Fan Cultures problematizes this exaltation of fans and offers a comprehensive examination of the current state of the field. Bringing together the latest international research, it explores the conceptualization of ‘the fan’ and the significance of relationships between fans and producers, with particular attention to the intersection between online spaces and offline places.

The purpose is to give an overview of the extent, range and nature of existing definitions of the concept ‘ageing in place’. Providing such an overview may be helpful, for policy makers, researchers, communities and service providers, to make sense of the versatility and uses of the concept, and allow the improvement and increase the success of efforts to contribute to the quality of life of older people. The overview was created using Arksey and O’Malley’s scoping review methodology. Out of 3,692 retrieved articles, 34 met the inclusion criteria. These studies concentrate on the following five key themes concerning ‘ageing in place’: ‘ageing in place’ in relation to place, to social networks, to support, to technology and to personal characteristics. Each of these key themes consists of other aspects, like physical place and attachment to place for the keyword place. This study concludes that the concept ‘ageing in place’ is broad and can be viewed from different (i.e. five) key themes. A more thorough understanding of ‘ageing in place’ provides knowledge about the existing key themes and aspects. These findings might provide practical support for professionals and governments when they develop their policies about ‘ageing in place’ integrally and to develop fit policies.
