Since the first release of modern electric vehicles, researchers and policy makers have shown interest in the deployment and utilization of charging infrastructure. Despite the sheer volume of literature, limited attention has been paid to the characteristics and variance of charging behavior of EV users. In this research, we answer the question: which scientific approaches can help us to understand the dynamics of charging behavior in charging infrastructures, in order to provide recommendations regarding a more effective deployment and utilization of these infrastructures. To do so, we propose a conceptual model for charging infrastructure as a social supply–demand system and apply complex system properties. Using this conceptual model, we estimate the rate complexity, using three developed ratios that relate to the (1) necessity of sharing resources, (2) probabilities of queuing, and (3) cascading impact of transactions on others. Based on a qualitative assessment of these ratios, we propose that public charging infrastructure can be characterized as a complex system. Based on our findings, we provide four recommendations to policy makers for taking efforts to reduce complexity during deployment and measure interactions between EV users using systemic metrics. We further point researchers and policy makers to agent-based simulation models that capture interactions between EV users and the use complex network analysis to reveal weak spots in charging networks or compare the charging infrastructure layouts of across cities worldwide.
In deze bijdrage presenteren we een aantal voorbeelden die laten zien dat verdieping van de unitstructuur een levensvatbaar alternatief is voor de vervanging van de unitstructuur door de multidimensionale organisatie (MDO), zoals voorgesteld door Strikwerda en Galbraith. In de MDO wordt gestreefd naar ‘resource efficiency’ en schaalvoordelen, terwijl het verdiepen van de unitstructuur gericht is op het bereiken van ‘flow efficiency’ en flow voordelen.
The valorization of biowaste, by exploiting side stream compounds as feedstock for the sustainable production of bio-based materials, is a key step towards a more circular economy. In this regard, chitin is as an abundant resource which is accessible as a waste compound of the seafood industry. From a commercial perspective, chitin is chemically converted into chitosan, which has multiple industrial applications. Although the potential of chitin has long been established, the majority of seafood waste containing chitin is still left unused. In addition, current processes which convert chitin into chitosan are sub-optimal and have a significant impact on the environment. As a result, there is a need for the development of innovative methods producing bio-based products from chitin. This project wants to contribute to these challenges by performing a feasibility study which demonstrates the microbial bioconversion of chitin to polyhydroxyalkanoates (PHAs). Specifically, the consortium will attempt to cultivate and engineer a recently discovered bacterium Chi5, so that it becomes able to directly produce PHAs from chitin present in solid shrimp shell waste. If successful, this project will provide a proof-of-concept for a versatile microbial production platform which can contribute to: i) the valorization of biowaste from the seafood industry, ii) the efficient utilization of chitin as feedstock, iii) the sustainable and (potentially low-cost) production of PHAs. The project consortium is composed of: i) Van Belzen B.V., a Dutch shrimp trading company which are highly interested in the valorization of their waste streams, hereby making their business model more profitable and sustainable. ii) AMIBM, which have recently isolated and characterized the Chi5 marine-based chitinolytic bacterium and iii) Zuyd, which will link aforementioned partners with students in creating a novel collaboration which will stimulate the development of students and the translation of academic knowledge to a feasible application technology for SME’s.
Het doel van dit interdisciplinaire SIA KIEM project Fluïde Eigenschap in de Creatieve Industrie is te onderzoeken of en hoe gedeelde vormen van eigenaarschap in de creatieve industrie kunnen bijdragen aan het creëren van een democratischer en duurzamer economie, waarin ook het MKB kan participeren in digitale innovatie. Het project geeft een overzicht van beschikbare vormen van (gedeeld) eigenaarschap, hun werking en hoe deze creatieve professionals kunnen ondersteunen bij de transitie naar de platformeconomie. Dit wordt toegepast op een concrete case, dat van een digitale breimachine. Naast het leveren van een goede praktijk, moet het project leiden tot een groter internationaal onderzoeksvoorstel over Fluid Ownership in the Creative Industry, dat dieper ingaat op de beschikbare eigendomsoplossingen en hoe deze waarde zullen creëren voor de creatieve professional.
HTIT-EN (Hospitality, Tourism, Innovation & Technology Experts Network) unites professors and researchers from five leading academies in hospitality and tourism (Hotelschool The Hague, Hotel Management School Maastricht / Zuyd, Breda University of Applied Sciences, Saxion Hogeschool, NHL Stenden). Our primary goal is to coordinate efforts in setting a joint research agenda, focused on the overall question: "How can the Dutch hospitality and tourism sector, which has a profound societal presence and encompasses a diverse range of workers and stakeholders, leverage its transversal character to generate extensive societal impact through the utilization of emerging technological innovations?" Early industry adoption of emerging technologies, including robotics, immersive experiences, and artificial intelligence, make hospitality and tourism ideal contexts to serve as a catalyst for innovation and societal impact. By integrating complementary expertise of the leading professors in areas like strategic foresight, disruptive transformations, technology management, and digital transformation and by engaging in collaboration with external knowledge institutions (MBO, HBO, WO), the Centre of Expertise Leisure, Tourism & Hospitality, business professionals, and industry associations, our vision is to acknowledge the hospitality and tourism industry as a dynamic basis for generating technology-driven, positive societal change. HTIT-EN's ultimate goal is to rise to the status of a globally renowned knowledge platform, specializing in technological innovation within the domain of hospitality and tourism, within the next 5 years. To achieve this aspiration, we are committed to fostering collaboration and aligning expertise across the participating institutions, as well as extending an invitation to additional partners from both the practical and academic fields related to this network. This collaborative effort will enable us to leverage each other’s expertise and resources and fully utilize the transversal characteristics of the Dutch tourism and hospitality industry, developing it to a catalyst for technology-driven innovation with wide and lasting societal implications across the Netherlands.
