Airport infrastructure evolves alongside legacy systems and processes that limits the ability to fully realise the efficiency potential of costly renovations. Airports will continue to take advantage of current and future technologies. Nevertheless, for such systems to work as efficiently as possible, the passenger should play an active role. This paper analyzes the effect of a new type of emerging ’smart passenger’, one that cooperates to be enabled to use the most efficient processes for a seamless experience. The technological and behavioural enhancements areassessed with the simulation of two case studies: London City and Palma de Mallorca airports. Results indicate that the introduction of this type of passenger brings benefit in terms of level of service indicators not only to this type of passenger but also to the traditional ones (business, visitor and leisure). However,the impact differs depending on the type of airport and the proportion of ’smart passengers’.
Nature-based strategies, such as wave attenuation by tidal marshes, are increasingly proposed as a complement to mitigate the risks of failure of engineered flood defense structures such as levees. However, recent analysis of historic coastal storms revealed smaller dike breach dimensions if there were natural, high tidal marshes in front of the dikes. Since tidal marshes naturally only experience weak flow velocities (~0-0.3 ms-1 during normal spring tides), we lack direct observations on the stability of tidal marsh sediments and vegetation under extreme flow velocities (order of several ms-1) as may occur when a dike behind a marsh breaches. As a first approximation, the stability of a tidal marsh sediment bed and winter-state vegetation under high flow velocities were tested in a flume. Marsh monoliths were excavated from Phragmites australis marshes in front of a dike along the Scheldt estuary (Dutch-Belgian border area) and installed in a 10 m long flume test section. Both sediment bed and vegetation responses were quantified over 6 experimental runs under high flow velocities up to 1.75 ms-1 and water depth up to 0.35 m for 2 hours. These tests showed that even after a cumulative 12 hours exposure to high flow velocities, erosion was limited to as little as a few millimeters. Manual removal of the aboveground vegetation did not enhance the erosion either. Present findings may be related to the strongly consolidated, clay- and silt-rich sediment and P. australis root system in this experiment. During the flow exposure, the P. australis stems were strongly bent by the water flow, but the majority of all shoots recovered rapidly when the flow had stopped. Although present results may not be blindly extrapolated to all other marsh types, they do provide a strong first indication that marshes can remain stable under high flow conditions, and confirm the potential of well-developed tidal marshes as a valuable extra natural barrier reducing flood discharges towards the hinterland, following a dike breach. These outcomes promote the consideration to implement tidal marshes as part of the overall flood defense and to rethink dike strengthening in the future.

Thermal disinfection is probably the oldest water treatment method ever used. Similarly to other disinfection processes, it targets the inactivation of pathogenic (micro)organisms present in water, wastewater and other media. In this work, a pilot-scale continuous-flow thermal disinfection system was investigated using highly contaminated hospital wastewater as influent without any pre-treatment step for turbidity removal. The results proved that the tested system can be used with influent turbidity as high as 100 NTU and still provide up to log 8 microbial inactivation. Further results have shown energy consumption comparable to other commercially available thermal disinfection systems and relatively low influence on the investigated physical–chemical parameters.

National forestry Commission (SBB) and National Park De Biesbosch. Subcontractor through NRITNational parks with large flows of visitors have to manage these flows carefully. Methods of data collection and analysis can be of help to support decision making. The case of the Biesbosch National Park is used to find innovative ways to figure flows of yachts, being the most important component of water traffic, and to create a model that allows the estimation of changes in yachting patterns resulting from policy measures. Recent policies oriented at building additional waterways, nature development areas and recreational concentrations in the park to manage the demands of recreation and nature conservation offer a good opportunity to apply this model. With a geographical information system (GIS), data obtained from aerial photographs and satellite images can be analyzed. The method of space syntax is used to determine and visualize characteristics of the network of leisure routes in the park and to evaluate impacts resulting from expected changes in the network that accompany the restructuring of waterways.
Chemical preservation is an important process that prevents foods, personal care products, woods and household products, such as paints and coatings, from undesirable change or decomposition by microbial growth. To date, many different chemical preservatives are commercially available, but they are also associated with health threats and severe negative environmental impact. The demand for novel, safe, and green chemical preservatives is growing, and this process is further accelerated by the European Green Deal. It is expected that by the year of 2050 (or even as soon as 2035), all preservatives that do not meet the ‘safe-by-design’ and ‘biodegradability’ criteria are banned from production and use. To meet these European goals, there is a large need for the development of green, circular, and bio-degradable antimicrobial compounds that can serve as alternatives for the currently available biocidals/ preservatives. Anthocyanins, derived from fruits and flowers, meet these sustainability goals. Furthermore, preliminary research at the Hanze University of Applied Science has confirmed the antimicrobial efficacy of rose and tulip anthocyanin extracts against an array of microbial species. Therefore, these molecules have the potential to serve as novel, sustainable chemical preservatives. In the current project we develop a strategy consisting of fractionation and state-of-the-art characterization methods of individual anthocyanins and subsequent in vitro screening to identify anthocyanin-molecules with potent antimicrobial efficacy for application in paints, coatings and other products. To our knowledge this is the first attempt that combines in-depth chemical characterization of individual anthocyanins in relation to their antimicrobial efficacy. Once developed, this strategy will allow us to single out anthocyanin molecules with antimicrobial properties and give us insight in structure-activity relations of individual anthocyanins. Our approach is the first step towards the development of anthocyanin molecules as novel, circular and biodegradable non-toxic plant-based preservatives.
De afgelopen twee decennia is er veel meer aandacht ontstaan bij onderzoekers en beleidsmakers voor het begrip co-creatie. Bijna altijd wordt de rol van co-creatie als positief en essentieel gezien in een proces waarin maatschappelijke of publieke uitdagingen worden onderzocht en opgelost (zogenaamde sociale innovatie). Het meeste onderzoek naar deze twee begrippen is kwalitatief van aard en gebaseerd op ‘case studies’.In zijn promotieonderzoek kijkt Peter Broekema naar de rol van co-creatie binnen sociale innovatie in Europese samenwerkingsprojecten. In zijn eerste artikel heeft hij de begrippen co-creatie en sociale innovatie tussen 1995 en 2018 binnen de EU geanalyseerd en geconcludeerd dat beide begrippen steeds breder gebruikt worden en samen met het begrip impact zijn getransformeerd tot een beleidsparadigma.In het tweede artikel keek Peter Broekema hoe beide begrippen doorwerken in specifieke subsidieoproepen en hoe consortia deze begrippen toepassen en samenwerken. Hierbij bleek dat er weliswaar verschillende typen consortia bestaan, maar dat zij geen specifieke co-creatiestrategie hadden.In zijn laatste twee artikelen zal hij gedetailleerd kijken naar een aantal EU projecten en vaststellen hoe de samenwerking is verlopen en hoe tevreden de verschillende partners zijn met het resultaat. Peter Broekema maakt hiervoor gebruik van projecten waarin hij zelf participeert (ACCOMPLISSH, INEDIT en SHIINE).EU beleidsparadigma van sociale innovatie in combinatie met co-creatie en impact. Co-creatie vindt vaak binnen eigen type stakehodlers plaatsAbstractSocial innovation and co-creation are both relatively new concepts, that have been studied by scholars for roughly twenty years and are still heavily contested. The former emerged as a response to the more technologically focused concept of innovation and the latter originally solely described the collaboration of end-users in the development of new products, processes or services. Between 2010-2015, both concepts have been adapted and started to be used more widely by for example EU policymakers in their effort to tackle so called ‘grand societal challenges’. Within this narrative – which could be called co-creation for social innovation, it is almost a prerequisite that partners – especially citizens - from different backgrounds and sectors actively work together towards specific societal challenges. Relevance and aimHowever, the exact contribution of co-creation to social innovation projects is still unclear. Most research on co-creation has been focussing on the involvement of end-users in the development of products, processes and services. In general, scholars conclude that the involvement of end-users is effective and leads to a higher level of customer satisfaction. Only recently, research into the involvement of citizens in social innovation projects has started to emerge. However, the majority of research on co-creation for social innovation has been focusing on collaborations between two types of partners in the quadruple helix (citizens, governments, enterprises and universities). Because of this, it is still unclear what co-creation in social innovation projects with more different type of partners entails exactly. More importantly however, is that most research has been based on national case studies in which partners from different sectors collaborate in a familiar ‘national’ setting. Normally institutional and/or cultural contexts influence co-creation (for example the ‘poldermodel’in the Netherlands or the more confrontational model in France), so by looking at projects in a central EU and different local contexts it becomes clear how context effects co-creation for social innovation.Therefore this project will analyse a number of international co-creation projects that aim for social innovation with different types of stakeholders in a European and multi-stakeholder setting.With this research we will find out what people in different contexts believe is co-creation and social innovation, how this process works in different contexts and how co-creation contributes to social innovation.Research question and - sub questionsThe project will answer the following question: “What is the added value of co-creation in European funded collaboration projects that aim for social innovation?” To answer the main question, the research has been subdivided into four sub questions:1) What is the assumed added value of co-creation for social innovation?2) How is the added value of co-creation for social innovation being expressed ex ante and ex post in EU projects that aim specifically for social innovation by co-creation?3) How do partners and stakeholders envision the co-creation process beforehand and continuously shape this process in EU projects to maximise social innovation?4) How do partners and stakeholders regard the added value of co-creation for social innovation in EU projects that that aim for social innovation?Key conceptsThe research will focus on the interplay between the two main concepts a) co-creation and b) social innovation. For now, we are using the following working definitions:a) co-creation is a non-linear process that involves multiple actors and stakeholders in the ideation, implementation and assessment of products, services, policies and systems with the aim of improving their efficiency and effectiveness, and the satisfaction of those who take part in the process.b) social innovation is the invention, development and implementation of new ideas with the purpose to (immediately) relieve and (eventually) solve social problems, which are in the long run directed at the social inclusion of individuals, groups or communities.It is clear that both definitions are quite opaque, but also distinguish roughly the same phases (ideation/invention, development, implementation and assessment) and also distinguish different levels (products/services, policies and systems). Both concepts will be studied within the policy framework of the EU, in which a specific value to both concepts has been attributed, mostly because policymakers regard co-creation with universities and end-users almost as a prerequisite for social innovation. Based on preliminary research, EU policies seem to define social innovation in close reation with ‘societal impact’, which could defined as: “the long lasting effect of an activity on society, because it is aimed at solving social problems”, and therefore in this specific context social innovation seems to encompasses societal impact. For now, I will use this working definition of social innovation and will closely look at the entanglement with impact in the first outlined paper.MethodologyIn general, I will use a qualitative mixed method approach and grounded theory to answer the main research question (mRQ). In order to better understand the added value of co-creation for social innovation in an EU policy setting, the research will:SubRQ1) start with an analysis of academic literature on co-creation and social impact. This analysis will be followed by and confronted with an analysis of EU policy documents. SubRQ2) use a qualitative data analysis at nineteen EU funded projects to understand how co-creation is envisoned within social innovation projects by using the quintuple helix approach (knowledge flows between partners and stakeholders in an EU setting) and the proposed social innovation journey model. By contrasting the findings from the QDA phase of the project with other research on social innovation we will be able to find arachetypes of social innovation in relation with the (perceived) added value of co-creation within social innovation. SubRQ3) These archetypes will be used to understand the process of co-creation for social innovation by looking closely at behavioural interactions within two social innovation projects. This close examination will be carried out by carrying out interviews with key stakeholders and partners and participant observation.SubRQ4) The archetypes will also be used to understand the perceived added value by looking closely at behavioural interactions within two social innovation projects. This close examination will be carried out by carrying out interviews with key stakeholders and partners and participant observation.ImpactThe project will contribute to a better understanding of the relationship between co-creation and social innovation on different levels:a) Theoretical: the research will analyse the concepts of co-creation and social innovation in relation to each other by looking at the origins of the concepts, the adaptation in different fields and the uptake within EU policies;b) Methodological: a model will be developed to study and understand the non-lineair process of co-creation within social innovation, by focusing on social innovation pathways and social innovation strategies within a quintuple helix setting (i) academia, ii) enterprises and iii) governments that work together to improve iv) society in an v) EU setting);c) Empirical: the project will (for the first time) collect data on behavioural interactions and the satisfaction levels of these interactions between stakeholders and partners in an EU project.d) Societal: the results of the research could be used to optimize the support for social innovation projects and also for the development of specific funding calls.
