Evaluation of the hydrological performance of grassed swales usually needs long-term monitoring data. At present, suitable techniques for simulating the hydrological performance using limited monitoring data are not available. Therefore, current study aims to investigate the relationship between saturated hydraulic conductivity (Ks) fitting results and rainfall characteristics of various events series length. Data from a full-scale grassed swale (Enschede, the Netherlands) were utilized as long-term rainfall event series length (95 rainfall events) on the fitting outcomes. Short-term rainfall event series were extracted from these long-term series and used as input in fitting into a multivariate nonlinear model between Ks and its influencing rainfall indicators (antecedent dry days, temperature, rainfall, rainfall duration, total rainfall, and seasonal factor (spring, summer, autumn, and winter, herein refer as 1, 2, 3, and 4). Comparison of short-term and long-term rainfall event series fitting results allowed to obtain a representative short-term series that leads to similar results with those using long-term series. A cluster analysis was conducted based on the fitting results of the representative rainfall event series with their rainfall event characteristics using average values of influencing rainfall indicators. The seasonal index (average value of seasonal factors) was found to be the most representative short rainfall event series indicator. Furthermore, a Bayesian network was proposed in the current study to predict if a given short-term rainfall event series is representative. It was validated by a data series (58 rainfall events) from another full-scale grassed swale located in Utrecht, the Netherlands. Results revealed that it is quite promising and useful to evaluate the representativeness of short-term rainfall event series used for long-term hydrological performance evaluation of grassed swales.

This report investigates prior experiences and impacts of the European Capital of Culture (ECoC) with the aim of informing preparation plans for Leeuwarden and Fryslân to organize the event in 2018. The longterm benefits that the ECoC tend to be both tangible through improvements in facilities, and intangible as self-confidence and pride increase as the result of celebrating the destination, its culture and history.

The current standard in accounting practice is the double-entry approach. Basis of the double-entry approach is that every financial event brings two equal and offsetting entries. Since these financial events are not automatically confirmed by both parties, the accounting quality can be improved. The blockchain mechanism possibly offers a different take on accounting. Based on an experimentation approach, data was collected to compare the double-entry method with the blockchain-based triple-entry method. The results show that the main difference concerns determining the completeness of the financial statement items. In the situation of double-entry accounting, segregation of duties is applied to do so. In the blockchain situation, the underlying mechanism of the blockchain already ensures this.

Recent developments in digital technology and consumer culture have created new opportunities for retail and brand event concepts which create value by offering more than solely marketing or transactions, but rather a place where passion is shared. This chapter will define the concept of ‘fashion space’ and consumer experience, and delves into strategies for creating experiences that both align with a brand’s ethos and identity and build brand communities. It will provide insight on creating strong shared brand experiences that integrate physical and digital spaces, AR and VR. These insights can be used for consumer spaces but also for media and buyer events, runway shows, test labs and showrooms. Since its launch in 2007, international fashion brand COS has focused on creating fashion spaces that build and reinforce a COS fashion community. COS retail stores with their extraordinary architecture, both traditional and contemporary, contribute stories and facilitate intense brand experiences. Moreover, COS’ dedication to share the artistic inspirations of its people led to collaborating on interactive and multi-sensory installations which allow consumers to affectively connect to the brand’s personality and values. Thus, the brand was able to establish itself firmly in the lifestyle of its customers, facilitating and developing their aesthetics and values.

Many nature-based solutions are seen as favourable and effective measures to increase urban resilience during more extreme weather events, by for example decrease high temperatures in summer. Since space is often scarce in urban environments, roofs have received increased attention in mitigating the consequences of climate change in urban areas. This resulted in a variety of roof systems of green and blue-green roofs designed as an integral part of the built environment due to their hydrological, insulative and biodiverse capacities. This study examined the impact of blue-green, and conventional roofs on roof surface temperatures, indoor temperatures and insulative properties of the building. Temperature sensors (IButtons) have been used for summer and winter measurements on roofs for early 20th century buildings in the city of Amsterdam (NL).The results indicate the strongest effect of blue-green roofs on surface temperatures in summer, with significantly lower surface temperatures (2-3°C) than for conventional roofs. During winter days, the surface temperatures were not significantly different on blue-green roofs than on conventional roofs. The measurements in the water crate layers of blue-green roofs show an all year-round temperature buffering effect. During hot summer days, the temperature in the water storage of the blue-green roof was much lower than other measured surfaces (up to 12 °C and 7 °C compared to gravel roofs and the blue-green roof substrate, respectively) and also experienced the least diurnal variation. Similarly, the empty water crate layer showed up to 3 °C higher minimum temperatures during cold winter nights. The measurements also show a small positive systematic effect on the indoor environment under a blue-green roof compared to traditional gravel roof type. The variation in indoor temperature is smaller underneath the blue-green roofs compared to the reference roofs during both warm and cold periods (0.19 – 0.35 °C reduction in STD). This suggests that rooms located under a blue-green roof are less sensitive to the outside air temperature and its natural diurnal variation.Although the effect on indoor thermal comfort seems to be small, blue-green roofs contribute to overall greening of the city. Second, thanks to the water storage the potential for growing biodiverse vegetation is higher than on extensive green roofs.

Onderzoekers van het MOVES-onderzoeksprogramma hebben een vierde whitepaper uitgebracht. In deze publicatie is de belangrijkste kennis over maatschappelijke effecten van topsportevenementen bij elkaar gebracht. Ook zijn er kennishiaten benoemd die richting geven aan vervolgonderzoek. De thema’s die worden behandeld zijn: sportdeelname, welzijn, sociale cohesie, trots en geluk. Daarnaast is beschreven op welke manier topsportevenementen als hefboom (‘podium’) gebruikt kunnen worden en hoe dat tot impact en legacy kan leiden. Dit whitepaper maakt deel uit van werkpakket 4.

Een fles rode wijn per dag drinken is ongezond, maar een glas per dag reduceert mogelijk de kans op hartkwalen. Dit is een voorbeeld van ‘hormese’: het verschijnsel dat een agens dat in grote hoeveelheden schadelijk is, bij lage doses juist gezond is. Iets vergelijkbaars geldt voor zonlicht: lage doses worden geassocieerd met positieve gezondseffecten, hoge doses met verbranden en een hogere kans op huidkanker. Er zijn onderzoekers die zich op het omstreden standpunt stellen dat ook ioniserende straling hormetische eigenschappen heeft. In dit artikel gaan we nader in op de verschillende standpunten omtrent lage-dosiseffecten, de argumenten voor en tegen hormese en de consequenties van recente inzichten.
