P02-04 Citizen science during Covid-19 pandemic to enhance an activating environment in a low-SES neighborhood

One neighborhood in Groningen, the Netherlands, is a neighborhood housing about 12,000 citizens with on average a low-SES background, showing a less healthy and active lifestyle. In the past, initiatives have been undertaken to promote active lifestyle by implementing outdoor facilities stimulating physical activity. However, use of facilities was poor due to lack of citizen involvement. Aim of this project was to engage citizens in the overall process of capturing, plan making and prototyping of concepts for an exercise-friendly physical and social environment.From January 2020 - May 2022 a Living Lab was run following the ‘Our Voice’ citizen science method. Participatory citizen science was applied in which a community of stakeholders (public/private parties) and citizens was built. The community addressed the problem by creating more insight in promoting/degrading features in the neighborhood concerning an active lifestyle. Citizens (n = 40) used the Stanford Neighborhood Discovery Tool, which allowed for systematic observations of the physical environment. Additionally, emergent research walks gave extra information on neighborhood barriers/facilitators next to Discovery Tool data. Collected data allowed citizens to brainstorm on possible solutions in sessions facilitated by the researchers. Solutions were presented to local government and further developed for implementation and realization.Use of the Discovery Tool created an overview of the neighborhood. Based on positive/negative features, new ideas were generated for improving exercise-friendliness. One example was a walking route along art objects in the neighborhood. Furthermore, a citizens work group was formed which discussed this route, and other ideas and prototypes, with local government. This group was also involved in realization of prototypes.Our project resulted in a citizen science approach which can be transferred to other neighborhoods. Use of Discovery Tool showed many benefits for neighborhood plan making. Early and continuous involvement of citizens will lead to more sustainable engagement and is a powerful method to create engagement around societal problems and social innovation in the field of Health Enhancing Physical Activity.A transferable method for neighborhood development based on citizen science was developed. Key feature in our method was integration of design thinking, citizen engagement, and use of digital tools.

Analysis of civic initiatives

This paper focuses on the topical and problematic area of social innovations. The aim of this paper is to develop an original approach to the allocation of social innovations, taking into account characteristics such as the degree of state participation, the scope of application, the type of initiations as well as the degree of novelty, which will be elaborated on further in this article. In order to achieve this goal, the forty-two most successful social innovations were identified and systematized. The results of this study demonstrated that 73.5% of social innovations are privately funded, most of them operating on an international level with a high degree of novelty. Moreover, 81% of all social innovations are civic initiatives. Social innovations play an important role in the growth of both developed and less developed countries alike as highlighted in our extensive analysis

Social initiatives around refugees

After the arrival of refugees in the Netherlands, many citizens wanted to act and help the social inclusion of refugees. Community initiatives emerged where some of the initiatives even grew into potential Social Enterprises. In this research we investigated the main issues initiatives around refugees encounter when growing into a social enterprise (RQ1). Through the organization of learning networks we gathered data form initiatives who were currently in this process. The two main issues that arose were making a good business model and in what way impact can be measured when the impact area is the social inclusion of refugees. Our second research question (RQ2) investigated in what way the social initiatives help refugees in their social inclusion process. For this research question we interviewed refugees whom where involved with one of the initiatives participating in our research. Our main findings are that the participants in this research are all trying to take control over their lives, learning how to make a change and are trying to achieve a life that is good for them. They attributed various benefits to their active participation in the initiatives. They all mention that they met new people, that the people who started the initiative were very helpful and that they liked participating.

Resource-Efficient Image Buffer Architecture for Neighborhood Processors

Neighborhood image processing operations on Field Programmable Gate Array (FPGA) are considered as memory intensive operations. A large memory bandwidth is required to transfer the required pixel data from external memory to the processing unit. On-chip image buffers are employed to reduce this data transfer rate. Conventional image buffers, implemented either by using FPGA logic resources or embedded memories are resource inefficient. They exhaust the limited FPGA resources quickly. Consequently, hardware implementation of neighborhood operations becomes expensive, and integrating them in resource constrained devices becomes unfeasible. This paper presents a resource efficient FPGA based on-chip buffer architecture. The proposed architecture utilizes full capacity of a single Xilinx BlockRAM (BRAM36 primitive) for storing multiple rows of input image. To get multiple pixels/clock in a user defined scan order, an efficient duty-cycle based memory accessing technique is coupled with a customized addressing circuitry. This accessing technique exploits switching capabilities of BRAM to read 4 pixels in a single clock cycle without degrading system frequency. The addressing circuitry provides multiple pixels/clock in any user defined scan order to implement a wide range of neighborhood operations. With the saving of 83% BRAM resources, the buffer architecture operates at 278 MHz on Xilinx Artix-7 FPGA with an efficiency of 1.3 clock/pixel. It is thus capable to fulfill real time image processing requirements for HD image resolution (1080 × 1920) @103 fcps.

Citizens’ initiatives in an onlife world

Citizen participation is booming, especially the number of urban bottom-up initiatives where information and communication technologies (ICT) are deployed is increasing rapidly. This growth is good news for society as recent historical research shows that the more citizens actively and persistently interfere with public issues, the more likely a society will be resilient. And yet, at the same time, a growing number of scholars argue that due to the unprecedented impact of ICT, the public sphere is at stake. How to understand both trends? How do the anti-‘public sphere’ developments relate to the growing number of citizens’ initiatives using ICT? And if these citizen initiatives can indeed be understood as manifestations of public spheres, how can ICT foster or hinder the development of these public spheres? These questions will be explored by analyzing a Dutch citizen initiative called ‘Buuv’ (an online ‘market’ place for and by local residents) from a ‘public sphere’ perspective. The author will turn to The human condition (1958) of Hannah Arendt in order to elaborate a ‘public sphere’ perspective. An Arendtian perspective (as any perspective) highlights, however, some aspects and underexposes other aspects. Furthermore, chances are that Arendt’s thoughts are somewhat outdated, in the sense that we now live in a world where the online and the offline life intertwine — an experience that is referred to with the term ‘onlife’. Bearing these remarks in mind, the author will elaborate on the value of Arendt’s ideas to 1) the endeavor of understanding current trends in society—more urban bottom-up initiatives and anti-‘public sphere’ developments due to the broad uptake of ICT—and 2) the endeavor of revitalizing the public sphere in an onlife world.
