Hackathon events have become increasingly popular in recent years as a modern tool for innovation in the education sector as they offer important learning advantages. Within the “INVITE” Erasmus+ project, four distinct hackathons were organized to bring together academic institutions, teachers, and students in the design of innovative international virtual and blended collaborations. In addition, as part of the “INVITE” project, an Open Interactive Digital Ecosystem (digital platform) has been developed to facilitate hackathons organization and was tested within two of the events. This platform can enhance hosting action-training programs providing a shared open resources space for educators to contact peers and design projects. All four hackathons were held during 2024 and their duration and type (onsite, blended, hybrid, and online) varied significantly. However, all hackathon topics were related to sustainability, SDGs, and Green Agenda. In total, more than 220 participants enrolled in the four events, including students, researchers, and professors from different disciplines, age groups, and countries. All participants were provided with qualitative surveys to explore their satisfaction and experiences. The results compare different hackathon setups to reveal valuable insights regarding the optimal design for higher education hackathons. Full article

Family violence is a social issue that impacts families and communities every day in Canada and around the world. As family violence rates continue to increase there is an urgent need for cross-sectoral collaboration to codesign social work and social service systems, in partnership with those experiencing family violence. This article will share learnings from a two-year community-based participatory research study that worked alongside survivors and witnesses of family violence, community partners from diverse social service agencies, and researchers, to understand experiences of family violence in racialized communities in Peel region, Ontario, Canada. An intersectional-trauma-informed approach guided the work that included establishing a community advisory board, hiring peer research assistants, Photovoice, and holding a knowledge exchange event (KEE) with survivors and witnesses of family violence, researchers, and community partners to rapidly generate ideas for intervention areas through a 25/10 crowdsourcing activity and codesign preliminary solutions through a mini hackathon. Key findings from the photovoice highlighted systemic failures and gaps experienced by those facing family violence. As we shifted into ideation, this preliminary focus on systems solidified and top ideas identified included barrier-free, culturally aware provision of services ranging from mental health supports, safe housing, financial independence, and accessing wrap-around services. Our work concluded with the collaborative development of preliminary solutions to these ideas and emphasized the need for cross-sectoral partnerships and lived experience engagement to change systems. Centering the voices of those who have experienced FV in system-level change and advocacy is necessary to ensure services and supports meet the needs of service users. Full article

Methodologies for future-oriented research are mutually beneficial in highlighting different methodological perspectives and proposals for extending higher-education didactics toward sustainability. This study explores how different augmented-reality applications can enable new ways of teaching and learning. It systematically investigates how student teachers (n = 18) in higher education experienced ongoing realities while designing learning activities for a hybrid conference and interconnecting sustainability knowings via didactic modeling and design thinking. This qualitative study aims to develop a conceptual hybrid framework concerning the implications of student teachers incorporating design thinking and inner transition into their professional work with future-oriented methodologies on didactic modeling for sustainability commitment. With a qualitative approach, data were collected during and after a hackathon-like workshop through student teachers’ reflections, post-workshop surveys, and observation field notes. The thematic analysis shed light on transgressive learning and a transition in sustainability mindset through the activation of inner dimensions. Findings reinforcing sustainability commitment evolved around the following categories: being authentic (intra-personal competence), collaborating co-creatively (interpersonal competence), thinking long-term-oriented (futures-thinking competence on implementing didactics understanding), relating to creative confidence (values-thinking competence as embodied engagement), and acting based on perseverant professional knowledge-driven change (bridging didactics) by connecting theory-loaded empiricism and empirically loaded theory. The results highlight some of the key features of future-oriented methodologies and approaches to future-oriented methodologies, which include collaboration, boundary crossing, and exploration, and show the conditions that can support or hinder methodological development and innovation.

In the realm of predictive toxicology for small molecules, the applicability domain of QSAR models is often limited by the coverage of the chemical space in the training set. Consequently, classical models fail to provide reliable predictions for wide classes of molecules. However, the emergence of innovative data collection methods such as intensive hackathons have promise to quickly expand the available chemical space for model construction. Combined with algorithmic refinement methods, these tools can address the challenges of toxicity prediction, enhancing both the robustness and applicability of the corresponding models. This study aimed to investigate the roles of gradient boosting and strategic data aggregation in enhancing the predictivity ability of models for the toxicity of small organic molecules. We focused on evaluating the impact of incorporating fragment features and expanding the chemical space, facilitated by a comprehensive dataset procured in an open hackathon. We used gradient boosting techniques, accounting for critical features such as the structural fragments or functional groups often associated with manifestations of toxicity. Full article

Climate change education is crucial for fostering informed and engaged future generations. However, traditional pedagogies often fail to engage learners fully and provide real-world, experiential learning. This paper presents a novel approach to climate change education through a three-day virtual reality (VR) hackathon. The hackathon focused on four United Nations (UN) Sustainable Development Goals (SDGs)—Quality Education, Affordable and Clean Energy, Sustainable Cities and Communities, and Climate Action. Using VR technology and game design software, engineering students worked in teams. They competed against each other in designing immersive environments that demonstrated their understanding of these SDGs and climate change. Our goal was to encourage the development of empathy, education, and awareness around these critical global issues. The hackathon also integrated authentic assessments, mirroring real-world engineering tasks and providing a more practical and relevant learning experience. Our findings suggest that this VR hackathon has significantly enhanced students’ understanding of the SDGs and climate change issues, their competency with VR technologies, as well as their teamwork and problem-solving skills. This paper discusses the hackathon’s design, implementation, and outcomes, highlighting the potential of such innovative approaches in tackling climate change education and awareness. Full article

Municipal solid waste (MSW) represents a significant global threat, which has to be managed by a model of production and consumption involving the sharing, leasing, reusing, repairing, refurbishing, and recycling of existing materials and products for as long as possible, otherwise known as a circular economy (CE). However, there is not a universal rule for waste recycling strategies, and it has been demonstrated that active public participation is crucial in the satisfactory management of waste. In this context, citizen participation and education are two interrelated approaches, which can help to engage and inform people regarding waste and its wider impact. The present study describes the development of an interdisciplinary hackathon (hackathons are events whereby individuals from different backgrounds are brought together to work on the solutions to different problems), targeted to students of a postgraduate Master’s course on Sustainable Development and Climate Change in order to develop and understand the MSW problems and priorities currently being targeted, with the aim to propose new potential solutions for MSW reduction, reuse, and recycling. Following an empirical approach, four working groups were established and assigned the following specific tasks: (i) communication/citizen education on MSW; (ii) the reduction of MSW production; (iii) innovative solutions to recover and enhance secondary raw materials deriving from MSW processing; and (iv) the eco-design of the cities of the future concerning CE principles applied to MSW recycling. Overall, the following main findings were derived from the hackathon event: (i) an essential objective of the CE strategy is to drive Europe’s internal market towards the production and consumption of more sustainable products, thus reducing environmental and social pressures, while still retaining value; (ii) the most effective ways of tackling environmental problems are to ‘change the way we consume’, as well as to ‘change the way we produce and trade’, with the responsibility shared between businesses, governments, and the EU, as well as the citizens themselves. In this scenario, research and innovation play a key role in driving the necessary systemic changes to reach climate neutrality and ensure an inclusive ecological and economic transition. Overall, the present study confirms how the hackathon represents an effective tool to engage citizens in participation and education. Full article

“Open Data” efforts are growing, especially in Europe, where open data are seen as a possible ethical driver of innovation. As smart cities continue to develop, it is important to explore how open data will affect the stakeholders of smart public spaces. Making data open and accessible not only has a managerial and technical component but also creates opportunities to shift power dynamics by granting individuals (and entities) access to data they might not otherwise be able to obtain. The scope of those who could access these data is wide, including data-illiterate citizens, burgeoning startups, and foreign militaries. This paper details the process of making data “open” from the MX3D smart bridge in Amsterdam through a “datathon”. The development and outcomes of opening the data and the event itself bring us closer to understanding the complexity of open data access and the extent to which it is useful or empowering for members of the public. While open data research continues to expand, there is still a dearth of studies that qualitatively detail the process and stakeholder concerns for a modern smart city project. This article serves to fill this gap. Full article

This paper describes an affordable robotic mobile 3D mapping system. It is built with Livox Mid–40 lidar with a conic field of view extended by a custom rotating planar reflector. This 3D sensor is compared with the more expensive Velodyne VLP 16 lidar. It is shown that the proposed sensor reaches satisfactory accuracy and range. Furthermore, it is able to preserve the metric accuracy and non–repetitive scanning pattern of the unmodified sensor. Due to preserving the non–repetitive scan pattern, our system is capable of covering the entire field of view of 38.4 × 360 degrees, which is an added value of conducted research. We show the calibration method, mechanical design, and synchronization details that are necessary to replicate our system. This work extends the applicability of solid–state lidars since the field of view can be reshaped with minimal loss of measurement properties. The solution was part of a system that was evaluated during the 3rd European Robotics Hackathon in the Zwentendorf Nuclear Power Plant. The experimental part of the paper demonstrates that our affordable robotic mobile 3D mapping system is capable of providing 3D maps of a nuclear facility that are comparable to the more expensive solution.

Blockchain smart contracts can support the decentralisation of business processes, but due to smart contracts’ specifics, their development is a complicated process. Introducing model-driven development principles in smart contract development can facilitate requirement specification, design, and implementation activities. This paper presents a model-driven development method MDAsmartCD (Model-Driven Architecture-based Smart Contract Development) to alleviate smart contract development by supporting the complete MDA life cycle, covering the definition of Computation-Independent Model, Platform-Independent Model, and two instances of Platform-Specific Models. In MDAsmartCD, model transformations (model-to-model and model-to-text) are used to produce smart contract code in the Hyperledger Fabric platform Go and the Ethereum platform Solidity programming languages. The method application was demonstrated by implementing the smart contract for the hackathon solution and executing the generated Solidity and Go smart contracts in the workflow of issuing certificates for hackathon participants. During the execution of the workflow, both deployed smart contracts behaved identically and recorded analogous results in respective blockchain data storages. This demonstrated that the MDAsmartCD method enables the generation of compilable and executable smart contract code, ready for deployment on a blockchain platform. Full article

It is increasingly recognized that community-based interventions for active ageing are more lasting and effective, yet the tools and methods for developing these interventions are lacking. This study investigates how to co-design community-based active ageing with older adults via the development of a toolkit to support this goal. Rapid reviews were conducted to understand (i) the effective behavioural change techniques for older adults, (ii) how to co-design with older adults for community-based interventions, and (iii) how to design tools for behaviour change that are easy to use. These reviews served as the foundation for developing a toolkit to support the co-design of community-based active ageing, which was evaluated during an interdisciplinary hackathon with older adults. Quantitative data from the surveys suggested that the confidence levels of students in developing interventions for health behaviour change and in co-designing with older adults increased after the hackathon, and the enjoyment of participating in the hackathon and of using the toolkit were statistically significant factors influencing this increase. Qualitative data from interviews and observations revealed how the toolkit was (un)used by the participants and what aspects of the toolkit can be improved. We encourage future researchers and practitioners to apply and adapt our research findings to the communities of older adults that they are working with. Full article

Efficient and robust search and rescue actions are always required when natural or technical disasters occur. Empowered by remote sensing techniques, building damage assessment can be achieved by fusing aerial images of pre- and post-disaster environments through computational models. Existing methods pay over-attention to assessment accuracy without considering model efficiency and uncertainty quantification in such a life-critical application. Thus, this article proposes an efficient and uncertain-aware decision support system (EUDSS) that evolves the recent computational models into an efficient decision support system, realizing the uncertainty during building damage assessment (BDA). Specifically, a new efficient and uncertain-aware BDA integrates the recent advances in computational models such as Fourier attention and Monte Carlo Dropout for uncertainty quantification efficiently. Meanwhile, a robust operation (RO) procedure is designed to invite experts for manual reviews if the uncertainty is high due to external factors such as cloud clutter and poor illumination. This procedure can prevent rescue teams from missing damaged houses during operations. The effectiveness of the proposed system is demonstrated on a public dataset from both quantitative and qualitative perspectives. The solution won the first place award in International Overhead Imagery Hackathon. Full article

Despite the fact that hackathons and digital innovation contests have emerged as substantial intermediaries in open innovation and entrepreneurship, knowledge about how hackathons and digital innovation contests impact innovation in cities is restricted. There is also a scarcity of models that aid in the organization of digital innovation contests. Based on the existing frameworks for contest organizations, the aim of this article is to present a case study which develops a framework for hosting and evaluating open data hackathons. The hackathon framework is developed from the organizer’s viewpoint, and it has been executed in three digital innovation competitions in Thessaloniki. The suggested scheme adds new knowledge to the field of open data and digital innovation competitions while also providing practitioners with opportunities to host digital contests. Moreover, this framework offers hackathon organizers with regulations and resources to help them plan innovation contests that contribute to the betterment of an open data ecosystem. Full article

Transforming the plastic industry toward producing more sustainable alternatives than conventional plastics, as an essential enabler of the bio-based circular economy (CE), requires reinforcing initiatives to drive solutions from the lab to the market. In this regard, startups and ideation and innovation events can potentially play significant roles in consolidating efforts and investments by academia and industry to foster bio-based and biodegradable plastic-related developments. This study aimed to present the current trends and challenges of bioplastics and bio-based materials as sustainable alternatives for plastics. On this basis, having conducted a systematic literature review, the seminal research themes of the bio-based materials and bioplastics literature were unfolded and discussed. Then, the most recent developments of bio-based sustainable products in Ukraine, as alternatives to petroleum-based plastics, that have gained publicity through local startup programs and hackathons were presented. The findings shed light on the potential of the bio-based sector to facilitate the CE transition through (i) rendering innovative solutions most of which have been less noticed in academia before; (ii) enhancing academic debate and bridging the gap between developers, scholars, and practitioners within the plastic industry toward creating circularity across the supply chain; (iii) identifying the main challenges and future perspectives for further investigations in the future.
