Urban ageing: prettig en succesvol ouder worden in de stad

Ook uit internationaal wetenschappelijk onderzoek blijkt dat er verschillen zijn tussen ouderen in de stad en op het platteland [3-5]. In de rijke delen van de Europese Unie hebben ouderen in de landelijke gebieden een hogere levenstevredenheid dan in de stad. Mensen lijken tevreden in een dorp, wellicht omdat het verwachtingspatroon geringer is. Als het op veroudering aankomt, biedt de hogere dichtheid van de stad een grotere nabijheid tot allerlei diensten die de kwaliteit van leven van ouderen vergroten. Door specifieke economische factoren kunnen deze diensten niet in dezelfde mate worden aangeboden in landelijke gebieden [6]. Woonomstandigheden, zo blijkt uit onderzoek [7], zijn beter voor onze ouderen in de stad dan op het platteland, hoewel de verschillen niet zo uitgesproken groot zijn. En dan heb je nog de gesegregeerde woonwijken voor ouderen, zoals in de Verenigde Staten. Denk daarbij aan Sun City Arizona en The Villages in Florida [8, 9]. Deze wijken bieden een eenheidsworst en zonderen ouderen af in een cocon van geboden comfort, waarbij zij verdwijnen uit het reguliere straatbeeld van omliggende steden. Een in vrijheid gekozen gevangenschap. Een echte seniorvriendelijke stad is een generatievriendelijke stad zoals u wilt, waar niet alleen ruimte is voor één generatie, maar voor alle generaties: van wieg tot graf.

What pupils can learn from working with robotic direct manipulation environments

This study investigates what pupils aged 10-12 can learn from working with robots, assuming that understanding robotics is a sign of technological literacy. We conducted cognitive and conceptual analysis to develop a frame of reference for determining pupils' understanding of robotics. Four perspectives were distinguished with increasing sophistication; psychological, technological, function, and controlled system. Using Lego Mindstorms NXT robots, as an example of a Direct Manipulation Environment, we developed and conducted a lesson plan to investigate pupils' reasoning patterns. There is ample evidence that pupils have little difficulty in understanding that robots are man-made technological and functional artifacts. Pupils' understanding of the controlled system concept, more specifically the complex sense-reason-act loop that is characteristic of robotics, can be fostered by means of problem solving tasks. The results are discussed with respect to pupils' developing technological literacy and the possibilities for teaching and learning in primary education.

The value of FM for a healthy urban environment

Co-Creation Dynamics in Urban Living Labs

Citizens and urban policy makers are experimenting with collaborative ways to tackle wicked urban issues, such as today’s sustainability challenges. In this article, we consider one particular way of collaboration in an experimental setting: Urban Living Labs (ULLs). ULLs are understood as spatially embedded sites for the co-creation of knowledge and solutions by conducting local experiments. As such, ULLs are supposed to offer an arena for reflexive, adaptive, and multi-actor learning environments, where new practices of self-organization and novel (infra-) structures can be tested within their real-world context. Yet, it remains understudied how the co-creation of knowledge and practices actually takes place within ULLs, and how co-creation unfolds their impacts. Hence, this paper focuses on co-creation dynamics in urban living labs, its associated learning and knowledge generation, and how these possibly contribute to urban sustainability transitions. We analyzed empirical data from a series of in-depth interviews and were actively involved with ULLs in the Rotterdam-The Hague region in the Netherlands. Our findings show five distinct types of co-creation elements that relate to specific dynamics of participation, facilitation, and organization. We conclude with a discussion on the ambivalent role of contextualized knowledge and the implications for sustainability transitions.

The Different Faces Of The Urban Digital Economy

What will a shopping street look like in 2025, when online shopping continues to show double-digit growth? And what will 3D printing do to factories and logistic companies, when we can ‘print’ more and more products at home or around the corner?The digital economy is one of the most pervasive game changers in cities. It creates and destroys, and affects the way cities function in many ways. But what is exactly the digital economy about? How big is it? Which types of transformation is it provoking in urban economies? And, importantly, what can local governments do to cope with the digital transition and foster sustainable urban development?

Different charging strategies for electric vehicle fleets in urban freight transport.

The transition from diesel-driven urban freight transport towards more electric urban freight transport turns out to be challenging in practice. A major concern for transport operators is how to find a reliable charging strategy for a larger electric vehicle fleet that provides flexibility based on different daily mission profiles within that fleet, while also minimizing costs. This contribution assesses the trade-off between a large battery pack and opportunity charging with regard to costs and operational constraints. Based on a case study with 39 electric freight vehicles that have been used by a parcel delivery company and a courier company in daily operations for over a year, various scenarios have been analyzed by means of a TCO analysis. Although a large battery allows for more flexibility in planning, opportunity charging can provide a feasible alternative, especially in the case of varying mission profiles. Additional personnel costs during opportunity charging can be avoided as much as possible by a well-integrated charging strategy, which can be realized by a reservation system that minimizes the risk of occupied charging stations and a dense network of charging stations.
