An explorative study of risk management by people with disabilities : A case study in the Netherlands
No full textThe mission and purpose of this engaged inclusive research, for and with persons with a visual- and/or hearing impairment (VI and/or HI) as experience experts, is to diminish the number of victims due to flooding. The study aims to investigate if and how these impaired persons are managing the risk of flooding in their various environments, influenced by their own background and by the ‘optimal quality’ of public authorities’ flood risk-handling. And indicate, if applicable, improvements for optimizing public authorities’ flood measures.
The results show that some of the impaired respondent’s background, their public authorities’ quality assessment and their own risk management give cause for concern. Being older, living in flood sensitive land parts, and not going outside if there are too many obstacles are hindrances when the risk of flooding becomes a real incident. The impaired respondents’ family structure is not suitable for implementing the public authorities’ ‘together-reliance’ measures against flooding and their income might not be enough for flood resistance measures. Public authorities’ measures against flooding, at the national and local level, are perceived by the impaired respondents, as not optimal. Self-efficacy and respect, values of utmost importance for the impaired respondents, are, from a non- nclusive able-bodied perspective, different from that of an impaired person’s point of view. This could cause misunderstandings during flood rescue missions. Raising awareness on flooding, providing more specific information and making the information more accessible is needed.
In ‘utilization of the results’, improvements are suggested. The impaired respondents capabilities of self-reliance, resilience and not privacy focused during incidents (COVID-19) could be of use. Our study added value to quality data of persons with an impairment and to the research on their flood risk management. The findings could result in less casualties and death in flooding events.
One sentence summary: This study presents an explorative approach on flooding for sensory impaired persons and findings show that respondents’ background, their authorities’ quality assessment and their risk management give cause for concern
Delta
Full text linkOde to the Bengal delta and to its poet, Rabindranath Tagore
This poetic reflection honors the Bengal Delta and the enduring spirit of Rabindranath Tagore, weaving imagery of tide, silt, and song to evoke a landscape shaped by both nature and cultural memory. Through shifting voices and fluid metaphors, this definition of Delta explores themes of liminality, ecological identity, and the tension between presence and erosion. It is an ode to a place where poetry is inseparable from geography, and where the act of dwelling becomes both ephemeral and eternal
Digital platforms for mobility services: Analyzing the current market landscape and European regulatory efforts
Full text linkThis paper analyses multimodal mobility platforms which enable the matching of supply and demand for transportation services, including new forms such as ride-hailing, ride-pooling, or vehicle sharing. Typically, such platforms appear as mobile applications (apps), sometimes evolving into “super apps” that even include non-transport services. This paper aims at answering the following research questions: (1) Which digital mobility platforms dominate the global market and how can they be characterized?; (2) What economic impacts can be expected for mobility companies from a possible EU regulation to facilitate platform-based bookings and multimodal travel (e.g., the EU Multimodal Digital Mobility Services (MDMS) initiative)?; and (3) Which overarching recommendations can be derived for policymakers concerning such a possible regulation? To investigate these questions, we first identify and characterize the most important mobility platforms based on data from an analytics firm for the mobile app market. The characteristics considered include platform usage, the number of integrated mobility services, and the countries in which they are operated. We then analyse statements from stakeholders collected during a public consultation on the EU MDMS initiative to identify significant SWOTs (strengths, weaknesses, opportunities, threats) for individual stakeholder groups in connection with such a possible future EU regulation. Based on this, we derive regulatory recommendations for policymakers
Assessing urban soil unsealing constraints and potential for water regulation: a framework and case study of Brussels-Capital Region
Full text linkAfter a functional and immaterial reduction of urban soil to a two-dimensional surface, dominating the urbanism of the 20th century, over the last decades, soil has been progressively restored as a material, urban, and living element.
This study proposes a comprehensive framework for assessing soil thickness within urban environments, emphasizing its threedimensional and multidisciplinary nature. The proposed framework conceptualizes soil as comprising three distinct strata: (1) the land surface, which underpins urban planning and zoning practices; (2) the living soil, a dynamic and biologically active stratum composed of various horizons and domains of pedology; and (3) the deep underground, comprising parent materials and geological formations typically studied by geologists. In urban contexts, these strata are subject to significant anthropogenic interference. In particular, the urban underground is often heavily constructed, accommodating basements, mobility networks, and technical infrastructure.
The proposed framework is applied to the case study of Brussels and aims to foster a soil-sensitive approach among urban designers and planners, thereby enabling site-specific unsealing and soil restoration practices. The application to Brussels reveals key insights into the benefits and constraints of soil unsealing, particularly concerning the soil\u27s function in water regulation. This study underscores the importance of considering soil in urban planning and offers a model for assessing the potential effectiveness of soil unsealing projects, ultimately promoting more resilient and sustainable urban environments
Geoanthropology and the variations of (land) loss: Counter currents of anthropogenic erosion in the Bengal Delta
Full text linkAn island named Ghoramara in the Bay of Bengal has lost 84 percent of its landmass over the last 100 years. Climate change-induced sea-level rise, however, does not explain the reason behind the extent of land lost from Ghoramara Island to the sea. What then, if not the rising waters, explains this erosion? This essay dwells on other causations. I draw on Kathryn Yusoff and Nigel Clark’s (2017) notion of the “geosocial”—that is, an invitation for the social to meet the geologic—as a means to understand this loss. I acknowledge the surprises of the earth’s strata and what cannot be controlled: shifts in the tectonic plates, the Bengal Delta’s eastward tilt that changed the course of the river, tides, and the forcefulness of sediments that make and unmake islands. At the same time, I reveal how the earth’s surface is being transformed through what Sheila Jasanoff (2015) calls “sociotechnical imaginaries.” Dams and barrages change the course of the rivers, trap sediments, and lead to downstream erosion; ports and shipping vessels that require dredging break new land formations; heavy and tall concrete embankments weigh the muddied coastlines down and often collapse with large chunks of land. Each of these mega-infrastructures (and many more) are responsible for the loss of land and act as impediments to the flourishing of humans and nonhumans on these watery lands. In a time of totalizing climate change narratives, in what is indeed an ongoing climate emergency, this essay hopes to move away from large abstractions toward regional ecological variations. Understanding the scars imposed on land and water by dams, ports, embankments and commercial shipping corridors provides the grounds upon which actors, interventions, infrastructures, and policies at regional, national, and deltaic levels can be held accountable for their direct attribution to erosion of land, lives, and life-worlds. Ultimately, pinpointing geosocial variations of land (and other) losses is one step towards reparative climate justice
Technological mediation of emotional practices: The case of AI in healthcare
Full text linkThe integration of AI-driven solutions in healthcare is revolutionizing various domains, spanning from pathology and radiology to neonatal intensive care and homecare. This transformative shift not only alters the workflows of healthcare professionals but also reshapes the experience of patients and informal caretakers. Amidst this development, an often-overlooked facet is the impact on emotional relationships among the diverse stakeholders in healthcare. This paper aims to cover this gap by combining insights from the theory of technological mediation and philosophy of emotions: by using the introduction of Artificial Intelligence (AI) in the healthcare field as an example, we showcase how the technological mediation approach has so far overlooked the role of moral emotions in the analysis of how technologies mediate moral life. By building on the concept of emotional attunement, we present an understanding of emotions as practices, where technologies act as mediators of the way in which subjects emotionally attune to each other. We subsequently argue that this mediation is revealed the moment technologies come to create frictions in the attuned emotional practice. These perturbations of emotional attunements are what we call ‘emotional glitches’. It is through glitches that moral and emotional mediation of technologies is revealed, thereby also highlighting normative aspects. We argue that studying moral technological mediation through emotional glitches can provide insightful observations on how these technologies should be developed and deployed

Full text linkFiltering Techniques for ADS-B Trajectory Preprocessing
Full text linkThis paper addresses the issue of noisy, uncertain and quantized data in crowdsourced ADS-B and Mode S data and explores propositions of implementations of preprocessing techniques to address them. After a description of ADS-B data focused on sources of noise and uncertainty, we present in detail a selection of filters that have been implemented in the traffic library, and widely used in the constitution of open datasets used in further research. We also illustrate the results of the filtering with trajectory data collected by The OpenSky Network and by inexpensive RTL-SDR receivers.

Addressing climate change impacts on food supply chain operations: An integrated framework for sustainable optimization
Full text linkClimate change exerts significant and multifaceted impacts on food supply chains, disrupting operations from production to consumption. This study investigates how climate-related vulnerabilities such as extreme weather events and climatic variability affect the efficiency, cost structure, and overall resilience of food supply chains, with a particular emphasis on disruptions that pose risks to the stability of food supply under uncertain climate conditions. These dimensions remain insufficiently explored in the current literature. To address this gap, a novel multi-objective optimization model is developed, incorporating Climate Vulnerability Indices (CVI) into the strategic planning of food supply chain networks. The model is formulated and solved using GAMS with the CPLEX solver, drawing on parameters derived from prior research in sustainable supply chain management. Results illustrate that integrating the CVI into supply chain decision-making enhances the model\u27s ability to account for climate-related risks, enabling more informed trade-offs among economic, environmental, and social objectives. Moreover, through its adaptive structure, the model promotes the long-term sustainability of food supply chains and supports continuity under climate-induced operational challenges. This study offers an innovative, resilience-focused modeling framework that supports sustainable and adaptive supply chain configurations. The findings underscore the critical need for climate-aware optimization approaches to enhance the resilience and sustainability of food systems amid escalating climate risks
