    Get PDF
    Floods are a devastating natural calamity that may seriously harm both infrastructure and people. Accurate flood forecasts and control are essential to lessen these effects and safeguard populations. By utilizing its capacity to handle massive amounts of data and provide accurate forecasts, deep learning has emerged as a potent tool for improving flood prediction and control. The current state of deep learning applications in flood forecasting and management is thoroughly reviewed in this work. The review discusses a variety of subjects, such as the data sources utilized, the deep learning models used, and the assessment measures adopted to judge their efficacy. It assesses current approaches critically and points out their advantages and disadvantages. The article also examines challenges with data accessibility, the interpretability of deep learning models, and ethical considerations in flood prediction. The report also describes potential directions for deep-learning research to enhance flood predictions and control. Incorporating uncertainty estimates into forecasts, integrating many data sources, developing hybrid models that mix deep learning with other methodologies, and enhancing the interpretability of deep learning models are a few of these. These research goals can help deep learning models become more precise and effective, which will result in better flood control plans and forecasts. Overall, this review is a useful resource for academics and professionals working on the topic of flood forecasting and management. By reviewing the current state of the art, emphasizing difficulties, and outlining potential areas for future study, it lays a solid basis. Communities may better prepare for and lessen the destructive effects of floods by implementing cutting-edge deep learning algorithms, thereby protecting people and infrastructure

    The Globalization of Artificial Intelligence: African Imaginaries of Technoscientific Futures

    Get PDF
    Imaginaries of artificial intelligence (AI) have transcended geographies of the Global North and become increasingly entangled with narratives of economic growth, progress, and modernity in Africa. This raises several issues such as the entanglement of AI with global technoscientific capitalism and its impact on the dissemination of AI in Africa. The lack of African perspectives on the development of AI exacerbates concerns of raciality and inclusion in the scientific research, circulation, and adoption of AI. My argument in this dissertation is that innovation in AI, in both its sociotechnical imaginaries and political economies, excludes marginalized countries, nations and communities in ways that not only bar their participation in the reception of AI, but also as being part and parcel of its creation. Underpinned by decolonial thinking, and perspectives from science and technology studies and African studies, this dissertation looks at how AI is reconfiguring the debate about development and modernization in Africa and the implications for local sociotechnical practices of AI innovation and governance. I examined AI in international development and industry across Kenya, Ghana, and Nigeria, by tracing Canada’s AI4D Africa program and following AI start-ups at AfriLabs. I used multi-sited case studies and discourse analysis to examine the data collected from interviews, participant observations, and documents. In the empirical chapters, I first examine how local actors understand the notion of decolonizing AI and show that it has become a sociotechnical imaginary. I then investigate the political economy of AI in Africa and argue that despite Western efforts to integrate the African AI ecosystem globally, the AI epistemic communities in the continent continue to be excluded from dominant AI innovation spaces. Finally, I examine the emergence of a Pan-African AI imaginary and argue that AI governance can be understood as a state-building experiment in post-colonial Africa. The main issue at stake is that the lack of African perspectives in AI leads to negative impacts on innovation and limits the fair distribution of the benefits of AI across nations, countries, and communities, while at the same time excludes globally marginalized epistemic communities from the imagination and creation of AI

    Get PDF
    The aviation industry is a dynamic and ever-evolving sector. As technology advances and becomes more sophisticated, the aviation industry must keep up with the changing trends. While some airlines have made investments in machine learning and mixed reality technologies, the vast majority of regional airlines continue to rely on inefficient strategies and lack digital applications. This paper investigates the state-of-the-art applications that integrate machine learning and mixed reality into the aviation industry. Smart aerospace engineering design, manufacturing, testing, and services are being explored to increase operator productivity. Autonomous systems, self-service systems, and data visualization systems are being researched to enhance passenger experience. This paper investigate safety, environmental, technological, cost, security, capacity, and regulatory challenges of smart aviation, as well as potential solutions to ensure future quality, reliability, and efficiency

    Facilitating prosociality through technology: Design to promote digital volunteerism

    Get PDF
    Volunteerism covers many activities involving no financial rewards for volunteers but which contribute to the common good. There is existing work in designing technology for volunteerism in HumanComputer Interaction (HCI) and related disciplines that focuses on motivation to improve performance, but it does not account for volunteer wellbeing. Here, I investigate digital volunteerism in three case studies with a focus on volunteer motivation, engagement, and wellbeing. My research involved volunteers and others in the volunteering context to generate recommendations for a volunteer-centric design for digital volunteerism. The thesis has three aims: 1. To investigate motivational aspects critical for enhancing digital volunteers’ experiences 2. To identify digital platform attributes linked to volunteer wellbeing 3. To create guidelines for effectively supporting volunteer engagement in digital volunteering platforms In the first case study I investigate the design of a chat widget for volunteers working in an organisation with a view to develop a design that improves their workflow and wellbeing. The second case study investigates the needs, motivations, and wellbeing of volunteers who help medical students improve their medical communication skills. An initial mixed-methods study was followed by an experiment comparing two design strategies to improve volunteer relatedness; an important indicator of wellbeing. The third case study looks into volunteer needs, experiences, motivations, and wellbeing with a focus on volunteer identity and meaning-making on a science-based research platform. I then analyse my findings from these case studies using the lens of care ethics to derive critical insights for design. The key contributions of this thesis are design strategies and critical insights, and a volunteer-centric design framework to enhance the motivation, wellbeing and engagement of digital volunteers

    Cyberbullying in educational context

    Get PDF
    Kustenmacher and Seiwert (2004) explain a man’s inclination to resort to technology in his interaction with the environment and society. Thus, the solution to the negative consequences of Cyberbullying in a technologically dominated society is represented by technology as part of the technological paradox (Tugui, 2009), in which man has a dual role, both slave and master, in the interaction with it. In this respect, it is noted that, notably after 2010, there have been many attempts to involve artificial intelligence (AI) to recognize, identify, limit or avoid the manifestation of aggressive behaviours of the CBB type. For an overview of the use of artificial intelligence in solving various problems related to CBB, we extracted works from the Scopus database that respond to the criterion of the existence of the words “cyberbullying” and “artificial intelligence” in the Title, Keywords and Abstract. These articles were the subject of the content analysis of the title and, subsequently, only those that are identified as a solution in the process of recognizing, identifying, limiting or avoiding the manifestation of CBB were kept in the following Table where we have these data synthesized and organized by years

    Contested environmental futures: rankings, forecasts and indicators as sociotechnical endeavours

    Get PDF
    In a world where numbers and science are often taken as the voice of truth and reason, Quantitative Devices (QDs) represent the epitome of policy driven by facts rather than hunches. Despite the scholarly interest in understanding the role of quantification in policy, the actual production of rankings, forecasts, indexes and other QDs has, to a great extent, been left unattended. While appendixes and technical notebooks offer an explanation of how these devices are produced, they exclude aspects of their making that are arbitrarily considered "mundane." It is in the everyday performances at research centres that the micropolitics of knowledge production, imaginaries, and frustrations merge. These are vital dimensions to understand the potential, limitations and ethical consequences of QDs. Using two participant observations as the starting point, this thesis offers a comprehensive critical analysis of the processes through which university-based research centres create QDs that represent the world. It addresses how researchers conceive quantitative data. It pays attention to the discourses of hope and expectation embedded in the devices. Finally, it considers the ethics of creating devices that cannot be replicated independently of their place of production. Two QDs were analysed: the Violence Early Warning System (ViEWS) and the Environmental Performance Index (EPI). At Uppsala University, researchers created ViEWS to forecast the probability of drought-driven conflicts within the next 100 years. The EPI, produced at the Yale Centre for Environmental Law and Policy, ranks the performance of countries' environmental policies. This thesis challenges existing claims within Science and Technology Studies and the Sociology of Quantification that QDs co-produce knowledge within their realms. I argue that these devices act as vehicles for sociotechnical infrastructures to be consolidated with little debate among policymakers, given their understanding as scientific and objective tools. Moreover, for an indicator to be incorporated within a QD, it needs to be deemed as relevant for those making the devices but also valuable enough to have been previously quantified by data providers. Even more, existing sociotechnical inequalities, power relations and epistemic injustices could impede disadvantaged communities' (e.g., in the Global South) ability to challenge metrics originated in centres in the Global North. This thesis, therefore, demonstrates how the future QDs propose is unilateral and does not acknowledge the myriad possibilities that might arise from a diversity of worldviews. In other words, they cast a future designed to fit under the current status quo. In sum, through two QDs focused on environmental-related, this thesis launches an inquiry into the elements that make up the imaginaries they propose following the everyday life of their producers. To achieve this, I discuss two core elements. First, the role of tacit knowledge and sociotechnical inequalities in reinforcing power relations between those with the means to quantify and those who might only accommodate proposed futures. Second, the dynamics between research centres and data providers in relation to what is quantified. By scrutinising mundanity, this work is a step forward in understanding the construction of sociotechnical imaginaries and infrastructures

    Platform://Democracy: Perspectives on Platform Power, Public Values and the Potential of Social Media Councils

    Social media platforms have created private communication orders which they rule through terms of service and algorithmic moderation practices. As their impact on public communication and human rights has grown, different models to increase the role of public interests and values in the design of their rules and their practices has, too. But who should speak for both the users and the public at large? Bodies of experts and/or selected user representatives, usually called Platform Councils of Social Media Councils (SMCs) have gained attention as a potential solution. Examples of Social Media Councils include Meta’s Oversight Board but most platforms companies have so far shied away from installing one. This survey of approaches to increasing the quality of platform decision-making and content governance involving more than 35 researchers from four continents brough to together in regional "research clinics" makes clear that trade-offs have to be carefully balanced. The larger the council, the less effective is its decision-making, even if its legitimacy might be increased. While there is no one-size-fits-all approach, the projects demonstrates that procedures matter, that multistakeholderism is a key concept for effective Social Media Councils, and that incorporating technical expertise and promoting inclusivity are important considerations in their design. As the Digital Services Act becomes effective in 2024, a Social Media Council for Germany’s Digital Services Coordinator (overseeing platforms) can serve as test case and should be closely monitored. Beyond national councils, there is strong case for a commission focused on ensuring human rights online can be modeled after the Venice Commission and can provide expertise and guidelines on policy questions related to platform governance, particularly those that affect public interests like special treatment for public figures, for mass media and algorithmic diversity. The commission can be staffed by a diverse set of experts from selected organizations and institutions established in the platform governance field
