    Multidisciplinary perspectives on Artificial Intelligence and the law

    Get PDF
    This open access book presents an interdisciplinary, multi-authored, edited collection of chapters on Artificial Intelligence (‘AI’) and the Law. AI technology has come to play a central role in the modern data economy. Through a combination of increased computing power, the growing availability of data and the advancement of algorithms, AI has now become an umbrella term for some of the most transformational technological breakthroughs of this age. The importance of AI stems from both the opportunities that it offers and the challenges that it entails. While AI applications hold the promise of economic growth and efficiency gains, they also create significant risks and uncertainty. The potential and perils of AI have thus come to dominate modern discussions of technology and ethics – and although AI was initially allowed to largely develop without guidelines or rules, few would deny that the law is set to play a fundamental role in shaping the future of AI. As the debate over AI is far from over, the need for rigorous analysis has never been greater. This book thus brings together contributors from different fields and backgrounds to explore how the law might provide answers to some of the most pressing questions raised by AI. An outcome of the Católica Research Centre for the Future of Law and its interdisciplinary working group on Law and Artificial Intelligence, it includes contributions by leading scholars in the fields of technology, ethics and the law.info:eu-repo/semantics/publishedVersio

    Handbook Transdisciplinary Learning

    Get PDF
    What is transdisciplinarity - and what are its methods? How does a living lab work? What is the purpose of citizen science, student-organized teaching and cooperative education? This handbook unpacks key terms and concepts to describe the range of transdisciplinary learning in the context of academic education. Transdisciplinary learning turns out to be a comprehensive innovation process in response to the major global challenges such as climate change, urbanization or migration. A reference work for students, lecturers, scientists, and anyone wanting to understand the profound changes in higher education

    On linear, fractional, and submodular optimization

    Get PDF
    In this thesis, we study four fundamental problems in the theory of optimization. 1. In fractional optimization, we are interested in minimizing a ratio of two functions over some domain. A well-known technique for solving this problem is the Newton– Dinkelbach method. We propose an accelerated version of this classical method and give a new analysis using the Bregman divergence. We show how it leads to improved or simplified results in three application areas. 2. The diameter of a polyhedron is the maximum length of a shortest path between any two vertices. The circuit diameter is a relaxation of this notion, whereby shortest paths are not restricted to edges of the polyhedron. For a polyhedron in standard equality form with constraint matrix A, we prove an upper bound on the circuit diameter that is quadratic in the rank of A and logarithmic in the circuit imbalance measure of A. We also give circuit augmentation algorithms for linear programming with similar iteration complexity. 3. The correlation gap of a set function is the ratio between its multilinear and concave extensions. We present improved lower bounds on the correlation gap of a matroid rank function, parametrized by the rank and girth of the matroid. We also prove that for a weighted matroid rank function, the worst correlation gap is achieved with uniform weights. Such improved lower bounds have direct applications in submodular maximization and mechanism design. 4. The last part of this thesis concerns parity games, a problem intimately related to linear programming. A parity game is an infinite-duration game between two players on a graph. The problem of deciding the winner lies in NP and co-NP, with no known polynomial algorithm to date. Many of the fastest (quasi-polynomial) algorithms have been unified via the concept of a universal tree. We propose a strategy iteration framework which can be applied on any universal tree

    Uncertainty in runtime verification : a survey

    Get PDF
    Runtime Verification can be defined as a collection of formal methods for studying the dynamic evaluation of execution traces against formal specifications. Aside from creating a monitor from specifications and building algorithms for the evaluation of the trace, the process of gathering events and making them available for the monitor and the communication between the system under analysis and the monitor are critical and important steps in the runtime verification process. In many situations and for a variety of reasons, the event trace could be incomplete or could contain imprecise events. When a missing or ambiguous event is detected, the monitor may be unable to deliver a sound verdict. In this survey, we review the literature dealing with the problem of monitoring with incomplete traces. We list the different causes of uncertainty that have been identified, and analyze their effect on the monitoring process. We identify and compare the different methods that have been proposed to perform monitoring on such traces, highlighting the advantages and drawbacks of each method

    Metaverse. Old urban issues in new virtual cities

    Get PDF
    Recent years have seen the arise of some early attempts to build virtual cities, utopias or affective dystopias in an embodied Internet, which in some respects appear to be the ultimate expression of the neoliberal city paradigma (even if virtual). Although there is an extensive disciplinary literature on the relationship between planning and virtual or augmented reality linked mainly to the gaming industry, this often avoids design and value issues. The observation of some of these early experiences - Decentraland, Minecraft, Liberland Metaverse, to name a few - poses important questions and problems that are gradually becoming inescapable for designers and urban planners, and allows us to make some partial considerations on the risks and potentialities of these early virtual cities

    The Self The Soul and The World: Affect Reason and Complexity

    Get PDF
    This book looks at the affective-cognitive roots of how the human mind inquires into the workings of nature and, more generally, how the mind confronts reality. Reality is an infinitely complex system, in virtue of which the mind can comprehend it only in bits and pieces, by making up interpretations of the myriads of signals received from the world by way of integrating those with information stored from the past. This constitutes a piecemeal interpretation by which we assemble our phenomenal reality. In perceiving the complex world and responding to it, the mind invokes the logic of affect and the logic of reason, the former mostly innate and implicit, and the latter generated consciously in explicit terms with reference to mind-independent relations between entities in nature. It is a strange combination of affect and reason that enables us to make decisions and inferences, --- the latter mostly of the inductive type --- thereby making possible the development of theories. Theories are our tool-kits for explaining and predicting phenomena, guiding us along in our journey in life. Theories, however, are defeasible, and need to be constantly updated, at times even radically. In this, the self and the soul are of enormous relevance. The former is the affect-based psychological engine driving all our mental processes, while the latter is the capacity of the conscious mind to examine and reconstruct the self by modulating repressed conflicts. If the soul remains inoperative, all our theories become misdirected and a rot spreads inexorably all around us

    Alone Together - Convergence Culture and the Slender Man Phenomenon

    Get PDF
    This project engages in a close examination of the Slender Man phenomenon, an online practice in which a community of pseudonymous enthusiasts share scary stories featuring a faceless, long-limbed, humanoid monster in a black business suit. The stories take various forms, including text-based narrative, amateur video, doctored images, and games. They are presented with an affectation of folklore, and treat the accounts as true testimonies of encounters they, or others they know, have allegedly had with Slender Man. This is a self-conscious effort on the part of its creators to manifest Slender Man as a real-life legend. Resulting from this effort, several individuals have carried out acts of real-world violence in the name of Slender Man, or with some connection to him. In response to these acts, and the ensuing moral panic, members of the community defensively stated that it was the responsibility of their readers to be able to know the difference between fantasy and reality. Yet, as this dissertation demonstrates, the Slender Man phenomenon itself is predicated on using digital media to blur this distinction. Through readings of Slender Man in various media forms, this dissertation shows how it blends horror aesthetics with the online cultures of trolling—in which individuals intentionally misrepresent themselves in order to mislead and antagonize others, allegedly for the lulz—that is, for the laughs, pranking or joking. Trolling has however produced many serious consequences, from individuals targeted for harassment to bad-faith political movements that disrupt existing institutional functions more broadly. In its origins, trolling began as apocryphal storytelling designed to mislead others into believing they were true and expose the ignorance of newbies. Notably, the sites in which this occurred evolved to become the fora from which the similarly apocryphal stories in the Slender Man text community originate, such as 4Chan. These same pseudonymous fora have acted as safe havens for bad actors that have gone on to become notorious for their promotion of real-world violence, from Erik Minassian’s violence in the name of the incel community to Elliot Rodger’s misogynistic manifesto posed to 4Chan. In short, this dissertation argues that Slender Man texts act as a canary in a coal mine, and that the mechanics of online horror communities lay bare the underlying strategies of trolling or post-truth internet culture more broadly. I undertake a close aesthetic and ideological examination of Slender Man in image, text, video and game, to offer a portrait of the community that shares them. The stories offer a glimpse into the anxieties, tensions, and alienation experienced in life online as a result of hypermediacy, premediacy, and anonymity. While much has been written regarding the potential for collaboration online and the possibilities for grassroots organization and community-building, the positive ends this convergence culture offers are offset to some extent by the kinds of anxieties emerging from a disaffected and alienated community. Ultimately, this project offers an account of the evolving relationship between interactive fiction, trolling, and political disaffection, a media ecology that is becoming ever more urgent to understand in twenty-first century society
