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 Furthermore, chances are that Arendt’s thoughts are somewhat outdated, in the sense that we now live in a world where the online and the offline life intertwine — an experience that is referred to with the term ‘onlife’.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.

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.

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.

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

Citizen science has demonstrated potential to foster local changes in public health, including physical (in)activity. We used community-engaged citizen science to explore how to improve the exercise-friendliness of a Dutch neighborhood, chosen because it scored below average on important health parameters.We followed the steps of design thinking and employed the Our Voice citizen science method to find out how community members perceived exercise-friendliness in their neighborhood. Members participated in technology-enabled “discovery” walks using the multi-lingual Stanford Neighborhood Discovery Tool mobile application. Positive, negative, and dual features in the neighborhood were captured. During a researcher-facilitated process, citizen scientists analyzed their data together, leading to overarching themes reflecting resident needs and desires. These themes served as the basis for developing a walking route throughout the neighborhood. Several initial walking route prototypes were developed and tested by citizen scientists, resulting in a final route design that was realized in collaboration with local government officials. Citizen scientists were interviewed and asked about their engagement with and sense of agency throughout the research process. They reported commitment to the project and their neighborhood, and a desire to contribute to society. They also reported increased agency in contributing to neighborhood impacts.This project showed that citizen science “by the people” is a powerful way to engage people with projects in their own neighborhoods. It provided local perspectives on the neighborhood, which led to actual changes in the environment

Exploratory analyses are an important first step in psychological research, particularly in problem-based research where various variables are often included from multiple theoretical perspectives not studied together in combination before. Notably, exploratory analyses aim to give first insights into how items and variables included in a study relate to each other. Typically, exploratory analyses involve computing bivariate correlations between items and variables and presenting them in a table. While this is suitable for relatively small data sets, such tables can easily become overwhelming when datasets contain a broad set of variables from multiple theories. We propose the Gaussian graphical model as a novel exploratory analyses tool and present a systematic roadmap to apply this model to explore relationships between items and variables in environmental psychology research. We demonstrate the use and value of the Gaussian graphical model to study relationships between a broad set of items and variables that are expected to explain the effectiveness of community energy initiatives in promoting sustainable energy behaviors.

Community energy can be conceptualized as a social movement, which aims to develop a sustainable, democratic, and localist energy system. Community energy organizations often take the form of cooperatives and strive for a high level of participation at the neighborhood level. Recently, community energy initiatives took on the challenge to develop neighborhood heating projects, which are citizen-led and sustainable. District heating (DH) projects are characterized by costly investments, a substantial overhaul of local infrastructure, and large installations for heat production. Furthermore, specialized technical knowledge is needed for the design of DH-systems.In the Netherlands, we studied four cases where local energy cooperatives developed such citizen-led neighborhood heating projects. Our primary research question is what constitutes a citizen-led or citizen-supported DH-project? We focus on four themes: first, the internal organization of the CH-project; second its outreach to local citizens; third, the role of technical knowledge and technology choices; fourth, the changing role of municipalities in the local energy transition.We developed a theoretical framework that consists of three main networks: the internal network, constituted by the local energy initiative itself and its surrounding neighborhood; the external network, which is comprised of local and regional governments as well as private companies; and the material network, referring to technological and physical aspects.In the discussion, we situate our findings against a broader European background. We conclude that a democratic structure, transparency of decision making, and a high level of activities to involve the neighborhood are key success factors. Nevertheless, the development of a community DH-project is a time-consuming process that takes a high toll on the participants. We observed that the remunicipalization trend is emerging in the Netherlands. Regarding technology choices, we found that the DH-initiatives became quite knowledgeable on technical issues and stimulated the application of new technologies such as small-scale aquathermal energy. However, in some cases the choice for a low-cost solution led to concessions to the sustainability of the proposed solutions.

This report, commissioned by Aeres University of Applied Sciences Almere, outlines how local food initiatives and other community support systems can help to enhance access to healthy food for socio-economically vulnerable groups in Almere. Through literature research, interviews with stakeholders, and a survey among the target group, the main accessibility barriers in accessing healthy food were identified. The results show that the availability of healthy food for socio-economically disadvantaged groups is not just influenced by financial constraints, but also by spatial, social, and knowledge aspects. The report provides concrete recommendations for meaningful change, such as better collaboration between actors, awareness raising, and spatial interventions in the food environment. These results can be used by policymakers, local initiatives, and other stakeholders do develop a more sustainable and equitable food strategy for Almere, where healthy food is accessible to everyone.Keywords: healthy food; Socio-economically vulnerable groups; Accessibility barriers; Recommendations for meaningful change; Food environment theory
