Expos, festivals and events have become increasingly important as tools of urban developmentin recent decades. The competitive drive to put cities on the global map has led many to adoptevent-based strategies, including the creation of ‘eventful cities’, ‘festival cities’ and ‘eventportfolios’. World Expos have taken on a particular significance as ‘pulsar events’ that canshape the host city through urban development, increased tourism and place branding. Eachhost city also uses the event in a different way, and gives it a unique flavour that tempers theeventual effects. This paper reviews the literature on World Expos and their effects, identifyingthemes including Place branding, Tourism flows, Resident attitudes and Architecture and urbandevelopment. It then analyses the experience of Barcelona, twofold Expo host and a‘paradigmatic’ example of a city developed through mega events.

People in western countries spend approximately 90% of their time indoors. This severely affects their health (WHO 2013; Klepeis et al. 2001). The health risks are exacerbated if people travel between indoor spaces by car or public transport. Buildings on streets specifically designed to create a human scale and connected with the street-space can potentially invite people to walk and enhance their engagement with their surroundings (O’Mara 2019; Ewing et al. 2013). Since the 1960s, influential empirical studies have raised awareness of the walkability of streets (e.g. Jacobs 2008) but reliable evidence on the effectiveness of applied design solutions remains scarce (Spanjar & Suurenbroek 2020). This eye-tracking study focused on the visual ‘scanning’ of streetscapes and people’s appreciation of applied design principles. The aim was to gather together lessons learned from a variety of streetscapes in cities around the world and use them to inform the design of new developments in the Netherlands. Google Street View was used to select 19 images of streets in high-density environments with human-scale attributes in their façades and street-spaces. They were presented in a randomized order in a laboratory setting to 40 participants, who viewed them for 5 seconds. The participants’ visual explorative behaviour was recorded with advanced eye-tracking technology. A survey recorded their overall appreciation of the scenes and mouse-tracking collated their specific areas of interest (see fig. 1). The comparative analysis of the participants’ aggregated eye-fixation images together with the supplementary methods suggests that certain attributes for creating a human scale catch the eye in the first few seconds and are highly appreciated. These include the variety of a street’s façades, a street’s enclosedness, and the level of detail in the transition zone between the private ground floor and the public street (see fig. 2). Green features are particularly valued and might have important restorative qualities for people who spend most of their time indoors (Kaplan 1995; Ulrich 1984). Future research should focus on the design of façades and the street-space itself, taking people’s indoor lives and related stress levels as a starting point.

Alcohol use disorder (AUD) is a major problem. In the USA alone there are 15 million people with an AUD and more than 950,000 Dutch people drink excessively. Worldwide, 3-8% of all deaths and 5% of all illnesses and injuries are attributable to AUD. Care faces challenges. For example, more than half of AUD patients relapse within a year of treatment. A solution for this is the use of Cue-Exposure-Therapy (CET). Clients are exposed to triggers through objects, people and environments that arouse craving. Virtual Reality (VRET) is used to experience these triggers in a realistic, safe, and personalized way. In this way, coping skills are trained to counteract alcohol cravings. The effectiveness of VRET has been (clinically) proven. However, the advent of AR technologies raises the question of exploring possibilities of Augmented-Reality-Exposure-Therapy (ARET). ARET enjoys the same benefits as VRET (such as a realistic safe experience). But because AR integrates virtual components into the real environment, with the body visible, it presumably evokes a different type of experience. This may increase the ecological validity of CET in treatment. In addition, ARET is cheaper to develop (fewer virtual elements) and clients/clinics have easier access to AR (via smartphone/tablet). In addition, new AR glasses are being developed, which solve disadvantages such as a smartphone screen that is too small. Despite the demand from practitioners, ARET has never been developed and researched around addiction. In this project, the first ARET prototype is developed around AUD in the treatment of alcohol addiction. The prototype is being developed based on Volumetric-Captured-Digital-Humans and made accessible for AR glasses, tablets and smartphones. The prototype will be based on RECOVRY, a VRET around AUD developed by the consortium. A prototype test among (ex)AUD clients will provide insight into needs and points for improvement from patient and care provider and into the effect of ARET compared to VRET.
Alcohol use disorder (AUD) is a pattern of alcohol use that involves having trouble controlling drinking behaviour, even when it causes health issues (addiction) or problems functioning in daily (social and professional) life. Moreover, festivals are a common place where large crowds of festival-goers experience challenges refusing or controlling alcohol and substance use. Studies have shown that interventions at festivals are still very problematic. ARise is the first project that wants to help prevent AUD at festivals using Augmented Reality (AR) as a tool to help people, particular festival visitors, to say no to alcohol (and other substances). ARise is based on the on the first Augmented Reality Exposure Therapy (ARET) in the world that we developed for clinical treatment of AUD. It is an AR smartphone driven application in which (potential) visitors are confronted with virtual humans that will try to seduce the user to accept an alcoholic beverage. These virtual humans are projected in the real physical context (of a festival), using innovative AR glasses. Using intuitive phone, voice and gesture interactions, it allows users to personalize the safe experience by choosing different drinks and virtual humans with different looks and levels of realism. ARET has been successfully developed and tested on (former) AUD patients within a clinical setting. Research with patients and healthcare specialists revealed the wish to further develop ARET as a prevention tool to reach people before being diagnosed with AUD and to extend the application for other substances (smoking and pills). In this project, festival visitors will experience ARise and provide feedback on the following topics: (a) experience, (b) awareness and confidence to refuse alcohol drinks, (c) intention to use ARise, (d) usability & efficiency (the level of realism needed), and (e) ideas on how to extend ARise with new substances.
The World Health Organization has pinpointed antimicrobial resistance (AMR) of increasing global concern, causing increased healthcare costs and threatening human health. Although AMR is a naturally occurring process, it is accelerated by misuse/overuse of antibiotics. Additionally, the development and production of antibiotics is becoming increasingly challenging and costly. These challenges underline the high demand for alternative microbial inhibitors (e.g. antibiotics) and their development. The chemical compound Allicin has been studied for its potential health benefits, including antimicrobial properties[1,2] and potential cardiovascular benefits[3]. It has been suggested that the antimicrobial effect of Allicin could be achieved indirectly by the imprint it leaves in surrounding water molecules, i.e. its hydration shell. Such imprints are known as time-crystals and possess unique properties. Since often biochemical reactions occur via water molecules and their hydrogen bonds, it is possible that a time-crystal imprint of a substance in water might have a similar effect as the substance itself, e.g. antimicrobial inhibition. A consortium of universities, knowledge institutes and companies was formed to test this hypothesis based on the antibacterial properties of Allicin, resulting in the project HyTimeCIA. The experiments involve attaching allicin onto a polymer surface (i.e. hybridization), thereby providing antibacterial properties. This surface is then exposed to bacteria to test the antimicrobial properties of the allicin/polymer surface. If proven feasible, HyTimeCIA could provide a novel alternative microbial inhibitor fixated to a surface, allowing for localized application of antibacterial effects and potentially reducing the requirement of antibiotics. This not only mitigates AMR, but also facilitates production of microbial inhibitors that are particularly difficult or expensive. From the partners perspective, HyTimeCIA provides opportunities for chemical-free alternative antimicrobial (water)treatment technology and gained knowledge on alternative microbial inhibitors, both aspects which are highly in demand due to AMR and antibiotic production challenges.
