De gemeente Den Haag heeft zeven outdoor fitness locaties aangelegd ter beweegstimulering van haar inwoners. Om inzicht te krijgen in het gebruik, belangrijke randvoorwaarden en succesfactoren van de Haagse ‘fitplaatsen’ heeft het lectoraat Gezonde Leefstijl in een Stimulerende Omgeving op vier dagen systematisch geobserveerd. Daarnaast zijn enquêtes en interviews afgenomen onder (niet-) gebruikers en professionals. Fitplaats Zuiderpark is de meest succesvolle locatie van de onderzochte fitplaatsen. Op alle observatiemomenten was hier een aanzienlijke groep mensen actief (gemiddeld 14 per uur). Op twee andere fitplaatsen (Strand en Ketelplein) zijn af en toe actieve mensen geobserveerd, maar op de overige fitplaatsen was per uur gemiddeld minder dan 1 persoon aanwezig. Bekendheid, zichtbaarheid, goede bereikbaarheid en goed onderhoud zijn belangrijke randvoorwaarden. De belangrijkste succesfactoren zijn promotie en begeleiding. Het merendeel van de Haagse fitplaatsen wordt momenteel niet optimaal gebruikt. Om hier verandering in aan te brengen is een stappenplan opgesteld.

Objectives: Promoting unstructured outside play is a promising vehicle to increase children’s physical activity (PA). This study investigates if factors of the social environment moderate the relationship between the perceived physical environment and outside play. Study design: 1875 parents from the KOALA Birth Cohort Study reported on their child’s outside play around age five years, and 1516 parents around age seven years. Linear mixed model analyses were performed to evaluate (moderating) relationships among factors of the social environment (parenting influences and social capital), the perceived physical environment, and outside play at age five and seven. Season was entered as a random factor in these analyses. Results: Accessibility of PA facilities, positive parental attitude towards PA and social capital were associated with more outside play, while parental concern and restriction of screen time were related with less outside play. We found two significant interactions; both involving parent perceived responsibility towards child PA participation. Conclusion: Although we found a limited number of interactions, this study demonstrated that the impact of the perceived physical environment may differ across levels of parent responsibility.

During the last twenty years, a remarkable new type of service has been developed in the world of sports, which can be described as the indoorisation of outdoor sports. Typical outdoor sports like climbing, skiing, surfing, rowing, and skydiving, which used to be exclusively practiced in a natural environment of mountains, oceans, rivers and the air, are now being offered for consumption in safe, predictable and controlled indoor centers. The present article emphasizes the rise of indoor lifestyle sports, such as rafting, snowboarding, skydiving and surfing. It discusses the conditions under and ways in which commercial entrepreneurs in the Netherlands have created this market, the meanings that they have ascribed to their centers and the dilemmas with which they have been confronted. It is argued that the rise of this economic market cannot be understood if it is solely interpreted as the result of economic, technological or natural developments. These economic activities were also embedded in and influenced by shared understandings and their representations in structured fields of outdoor sports, mainstream sports and leisure experience activities. A better understanding of the indoorisation of outdoor lifestyle sports can be achieved by recognizing how these structures and cultures pervaded the rise of this new market.

Drones have been verified as the camera of 2024 due to the enormous exponential growth in terms of the relevant technologies and applications such as smart agriculture, transportation, inspection, logistics, surveillance and interaction. Therefore, the commercial solutions to deploy drones in different working places have become a crucial demand for companies. Warehouses are one of the most promising industrial domains to utilize drones to automate different operations such as inventory scanning, goods transportation to the delivery lines, area monitoring on demand and so on. On the other hands, deploying drones (or even mobile robots) in such challenging environment needs to enable accurate state estimation in terms of position and orientation to allow autonomous navigation. This is because GPS signals are not available in warehouses due to the obstruction by the closed-sky areas and the signal deflection by structures. Vision-based positioning systems are the most promising techniques to achieve reliable position estimation in indoor environments. This is because of using low-cost sensors (cameras), the utilization of dense environmental features and the possibilities to operate in indoor/outdoor areas. Therefore, this proposal aims to address a crucial question for industrial applications with our industrial partners to explore limitations and develop solutions towards robust state estimation of drones in challenging environments such as warehouses and greenhouses. The results of this project will be used as the baseline to develop other navigation technologies towards full autonomous deployment of drones such as mapping, localization, docking and maneuvering to safely deploy drones in GPS-denied areas.
Hoogwaardig afvalhout van bewoners, bouwbedrijven en meubelmakers blijft momenteel ongebruikt omdat het te arbeidsintensief is om grote hoeveelheden ongelijke stukken hout van verschillende afmetingen en soorten te verwerken. Waardevol hout wordt waardeloos afval, tegen de principes van de circulaire economie in. In CW.Code werken Powerhouse Company, Bureau HUNC en Vrijpaleis samen met de HvA om te onderzoeken hoe een toegankelijke ontwerptool te ontwikkelen om upcycling en waardecreatie van afvalhout te faciliteren. In andere projecten hebben HvA en partners verschillende objecten gemaakt van afvalhout: een stoel, een receptiebalie, kleine meubels en objecten voor de openbare ruimte, vervaardigd met industriële robots. Deze objecten zijn 3D gemodelleerd met behulp van specifieke algoritmen, in de algemeen gebruikte ontwerpsoftware Rhino en Grasshopper. De projectpartners willen nu onderzoeken hoe deze algoritmen via een toegankelijke tool bruikbaar te maken voor creatieve praktijken. Deze tool integreert generatieve ontwerpalgoritmen en regelsets die rekening houden met beschikbaar afvalhout, en de ecologische, financiële en sociale impact van resulterende ontwerpen evalueren. De belangrijkste ontwerpparameters kunnen worden gemanipuleerd door ontwerpers en/of eindgebruikers, waardoor het een waardevol hulpmiddel wordt voor het co-creëren van circulaire toepassingen voor afvalhout. Dit onderzoek wordt uitgevoerd door HvA Digital Production Research Group, met bovengenoemde partners. HUNC heeft ervaring met stadsontwikkeling waarbij gebruik wordt gemaakt van lokaal gekapt afvalhout. Vrijpaleis biedt toegang tot een actieve, lokale community van makers met een sterke band met buurtbewoners. Powerhouse Company heeft ervaring in het ontwerpen met hout in de bouw. Alle drie kunnen profiteren van slimmere circulaire ontwerptools, waarbij beschikbaar materiaal, productiebeperkingen en impactevaluatie worden geïntegreerd. De tool wordt ontwikkeld en getest voor twee designcases: een binnenmeubelobject en een buitengevelelement. Bevindingen hiervan zullen leidend zijn bij de ontwikkeling van de tool. Na afronding van het project is een bètaversie gereed voor validatie door ontwerpers, bewonerscollectieven en onderzoek/onderwijs van de HvA.
In recent years, organizations across Europe, and the Netherlands in particular, have increasingly supported efforts to enhance the sustainability of festivals such as the European Climate Pact, launched by the European Commission as part of the European Green Deal, European Festivals Association and Green Deals Circular Festivals in the Netherlands (European Union [EU], 2025). As a result, festivals across Europe are growing their environmental stewardship and serving as prototypes for wider societal transitions towards sustainability (Calvano, 2024; Irimiás et; al., 2024). However, festival organizers and other stakeholders still face challenges in developing effective communication strategies that truly activate more sustainable behaviour among festival goers (Harms et. al., 2023). Generic, one-size-fits-all approaches are often applied, yet they tend to have limited impact. This is also due to the diverse nature of music festivals, ranging from indoor to outdoor settings, single-day events to multi-day experiences, and from urban to rural locations, all of which shape the audience, context, and communication needs in unique ways (Tölkes & Butzmann, 2018; Dodds et. al., 2020). Essentially, festivals are ideal for informing, experiencing and activating sustainable behavioural change through effective communication before, during and after festivals. It is therefore crucial that a more targeted approach is utilized where messages can be tailored to make communication more effective (Temmerman & Veeckman, 2024). To address pressing sustainable and social challenges within the festival sector, NHL Stenden (NHLS) will collaborate with ESNS and Thansk on a design research project. In partnership with a network of festival organizers, industry professionals, and experts, the project will explore effective communication strategies for sustainability. The goal is to develop an actionable, research-informed roadmap that supports music festivals in enhancing their sustainability communication tailored to the sector’s dynamic and diverse nature.
