Space Governance: Challenges, Threats and Countermeasures (Space Law and Policy)
by Hamid Jahankhani Stefan Kendzierskyj Maria A. Pozza Sina PournouriThis book delves into the complexities of space governance, offering innovative solutions for a sustainable future. From the pressing issues facing space governance today to creating a consensus on responsibility, ethics, and frameworks, we aim to answer key questions: (i) What are the current challenges? (ii) How do satellites impact society? (iii) What are the potential negative consequences? From communication and early warning systems to global broadcasting and navigation, satellite technology plays a pivotal role in our daily lives. However, this reliance also exposes vulnerabilities, as any disruption to satellite systems could have disastrous consequences across multiple industries. The rapid development of satellite technology, including drones and UAVs, has ushered in a new era of exploration and exploitation. Yet, this progress brings with it new challenges, particularly in terms of governance. As satellites transcend national boundaries, the dynamics of space governance become increasingly complex, with various entities pursuing their own interests without always considering the broader implications. This book bridges the knowledge gap surrounding space technology and highlights the need for increased governance frameworks, data protection, and disciplined deployment. By addressing issues of control, privacy, and security, we pave the way for a more sustainable and responsible approach to space exploration. Join us on this journey as we navigate the evolving landscape of space governance and chart a course towards a brighter future for all.

Space and Play in Japanese Videogame Arcades (Routledge Contemporary Japan Series)
by Jérémie Pelletier-GagnonThis book presents a scholarly investigation of the development and culture of Japanese videogame arcades, both from a historical and contemporary point of view.Providing an overview of the historical evolution of public amusement spaces from the early rooftop amusement spaces from the early nineteenth century to the modern multi‑floor and interconnected arcade complexes that characterize the urban fabric of contemporary Japan, the book argues that arcade videogames and their associated practices must be examined in the context in which they are played, situated in the interrelation between the game software, the cabinets as material conditions of play, and the space of the venue that frames the experience. Including three case studies of distinct and significant game centres located in Tokyo and Kyoto, the book addresses of play in public, including the notion of performance and observation as play practices, spatial appropriation, as well as the compartmentalization of the play experience.In treating videogames as sets of circumstances, the book identifies the opportunities for ludic practices that videogame arcades provide in Japan. As such, it will appeal to students and scholars of Game Studies and Digital Media Studies, as well as those of Japanese Culture and Society.
Space, Place and Global Digital Work
by Jörg FleckerThis edited volume seeks to enhance our understanding of the concepts of space and place in the study of digital work. It argues that while digital work is often presented as 'placeless', work always takes place somewhere with a certain degree of local embeddedness. Contributors to this collection address restructuring processes that bring about delocalised digital work and point out limitations to dislocation inherent in the work itself, and the social relations or the physical artefacts involved. Exploring the dynamics of global value chains and shifts in the international division of labour, this book explores the impact these have on employment and working conditions, workers' agency in shaping and coping with changes in work, and the new competencies needed in virtual organisational environments. Combining different disciplinary perspectives, the volume teases out the spatial aspects of digital work at different scales ranging from team level to that of global production networks.
Space-Air-Ground Integrated Network Security
by Wei Zhang Lin Bai Chunxiao Jiang Jianwei LiuThis book focuses on security science and technology, data and information security, and mobile and network security for space-air-ground integrated networks (SAGINs). SAGIN are expected to play an increasingly important role in providing real-time, flexible, and integrated communication and data transmission services in an efficient manner. Today, SAGINs have been widely developed for a range of applications in navigation, environmental monitoring, traffic management, counter-terrorism, etc. However, security becomes a major concern, since the satellites, spacecrafts, and aircrafts are susceptible to a variety of traditional/specific network-based attacks, including eavesdropping, session hijacking, and illegal access. In this book, we review the theoretical foundations of SAGIN security. We also address a range of related security threats and provide cutting-edge solutions in the aspect of ground network security, airborne network security, space network security, and provide future trends in SAGIN security. The book goes from an introduction to the topic’s background, to a description of the basic theory, and then to cutting-edge technologies, making it suitable for readers at all levels including professional researchers and beginners. To gain the most from the book, readers should have taken prior courses in information theory, cryptography, network security, etc.
Space-Filling Curves
by Michael BaderThe present book provides an introduction to using space-filling curves (SFC) as tools in scientific computing. Special focus is laid on the representation of SFC and on resulting algorithms. For example, grammar-based techniques are introduced for traversals of Cartesian and octree-type meshes, and arithmetisation of SFC is explained to compute SFC mappings and indexings. The locality properties of SFC are discussed in detail, together with their importance for algorithms. Templates for parallelisation and cache-efficient algorithms are presented to reflect the most important applications of SFC in scientific computing. Special attention is also given to the interplay of adaptive mesh refinement and SFC, including the structured refinement of triangular and tetrahedral grids. For each topic, a short overview is given on the most important publications and recent research activities.
Space-Time Geometries for Motion and Perception in the Brain and the Arts (Lecture Notes in Morphogenesis)
by Alain Berthoz Tamar FlashThis book is based on a two-day symposium at the Paris Institute of Advanced Study titled "space-time geometries and movement in the brain and the arts". It includes over 20 chapters written by the leading scientists and artists who presented their related research studies at the symposium and includes six sections; the first three focus on space-time geometries in perception, action and memory while the last three focus on specific artistic domains: drawing and painting, dance, music, digital arts and robotics. The book is accompanied by a dedicated webpage including related images and videos. There is an ever-growing interest in the topics covered by this book. Space and time are of fundamental importance for our understanding of human perception, action, memory and cognition, and are entities which are equally important in physics, biology, neuroscience and psychology. Highly prominent scientists and mathematicians have expressed their belief that our bodies and minds shape the ways we perceive space and time and the physical laws we formulate. Understanding how the brain perceives motion and generates -bodily movements is of great significance. There is also growing interest in studying how space, time and movement subserve artistic creations in different artistic modalities (e.g., fine arts, digital and performing arts and music). This interest is inspired by the idea that artists make intuitive use of the principles and simplifying strategies used by the brain in movement generation and perception. Building upon new understanding of the spatio-temporal geometries subserving movement generation and perception by the brain we can start exploring how artists make use of such neuro --geometrical and neuro-dynamic representations in order to express artistic concepts and emotionally affect the human observers and listeners. Scientists have also started formulating new ideas of how aesthetic judgements emerge from the principles and brain mechanisms subserving motor control and motion perception.Covering novel and multidisciplinary topics, this advanced book will be of interest to neuroscientists, behavioral scientists, artificial intelligence and robotics experts, students and artists.

Spaces Mapped and Monstrous: Digital 3D Cinema and Visual Culture (Film and Culture Series)
by Nick JonesDigital 3D has become a core feature of the twenty-first-century visual landscape. Yet 3D cinema is a contradictory media form: producing spaces that are highly regimented and exhaustively detailed, it simultaneously relies upon distortions of vision and space that are inherently strange.Spaces Mapped and Monstrous explores the paradoxical nature of 3D cinema to offer a critical analysis of an inescapable part of contemporary culture. Considering 3D’s distinctive visual qualities and its connections to wider digital systems, Nick Jones situates the production and exhibition of 3D cinema within a web of aesthetic, technological, and historical contexts. He examines 3D’s relationship with computer interfaces, virtual reality, and digital networks as well as tracing its lineage to predigital models of visual organization. Jones emphasizes that 3D is not only a technology used in films but also a tool for producing, controlling, and distorting space within systems of surveillance, corporatization, and militarization. The book features detailed analysis of a wide range of films—including Avatar (2009), Goodbye to Language (2014), Love (2015), and Clash of the Titans (2010)—demonstrating that 3D is not merely an augmentation of 2D cinema but that it has its own unique properties. Spaces Mapped and Monstrous brings together media archaeology, digital theory, and textual analysis to provide a new account of the importance of 3D to visual culture today.
Spaces of Teaching and Learning
by Peter Goodyear Robert A. EllisThis integrated collection of perspectives on the spaces of teaching and learning uses ‘learning space’ to place educational practice in context. It considers the complex relationships involved in the design, management and use of contemporary learning spaces. It sheds light on some of the problems of connecting the characteristics of spaces to the practices and outcomes of teaching and learning. The contributions show how research into learning spaces can inform broader educational practices and how the practices of teaching, learning and design can inform research. The selection of chapters demonstrates the value of gathering together multiple sources of evidence, viewed through different epistemological lenses in order to push the field forward in a timely fashion. The book provides both a broad review of current practices as well as a deep-dive into particular educational and epistemological challenges that the various approaches adopted entail. Contrasts and commonalities between the different approaches emphasise the importance of developing a broad, robust evidence-base for practice in context. This is the inaugural book in the series Understanding Teaching-Learning Practice.

Spam Nation: The Inside Story of Organized Cybercrime—from Global Epidemic to Your Front Door
by Brian KrebsA New York Times bestseller and winner of a 2015 Prose Award!There is a threat lurking online. A secret war with the power to destroy your finances, steal your personal data, and endanger your life.In Spam Nation, investigative journalist and cybersecurity expert Brian Krebs unmasks the criminal masterminds driving some of the biggest spam and hacker operations targeting Americans and their bank accounts. Tracing the rise, fall, and alarming resurrection of the digital mafia behind the two largest spam pharmacies—and countless viruses, phishing, and spyware attacks—he delivers the first definitive narrative of the global spam problem and its threat to consumers everywhere.Blending cutting-edge research, investigative reporting, and firsthand interviews, this terrifying true story reveals how we unwittingly invite these digital thieves into our lives every day. From unassuming computer programmers right next door to digital mobsters like "Cosma"—who unleashed a massive malware attack that has stolen thousands of Americans' logins and passwords—Krebs uncovers the shocking lengths to which these people will go to profit from our data and our wallets.Not only are hundreds of thousands of Americans exposing themselves to fraud and dangerously toxic products from rogue online pharmacies, but even those who never open junk messages are at risk. As Krebs notes, spammers can—and do—hack into accounts through these emails, harvest personal information like usernames and passwords, and sell them on the digital black market. The fallout from this global epidemic doesn't just cost consumers and companies billions, it costs lives too.Fast-paced and utterly gripping, Spam Nation ultimately proposes concrete solutions for protecting ourselves online and stemming this tidal wave of cybercrime—before it's too late."Krebs's talent for exposing the weaknesses in online security has earned him respect in the IT business and loathing among cybercriminals… His track record of scoops...has helped him become the rare blogger who supports himself on the strength of his reputation for hard-nosed reporting." —Bloomberg Businessweek
Spam: A Shadow History of the Internet (Infrastructures)
by Finn BruntonWhat spam is, how it works, and how it has shaped online communities and the Internet itself.The vast majority of all email sent every day is spam, a variety of idiosyncratically spelled requests to provide account information, invitations to spend money on dubious products, and pleas to send cash overseas. Most of it is caught by filters before ever reaching an in-box. Where does it come from? As Finn Brunton explains in Spam, it is produced and shaped by many different populations around the world: programmers, con artists, bots and their botmasters, pharmaceutical merchants, marketers, identity thieves, crooked bankers and their victims, cops, lawyers, network security professionals, vigilantes, and hackers. Every time we go online, we participate in the system of spam, with choices, refusals, and purchases the consequences of which we may not understand.This is a book about what spam is, how it works, and what it means. Brunton provides a cultural history that stretches from pranks on early computer networks to the construction of a global criminal infrastructure. The history of spam, Brunton shows us, is a shadow history of the Internet itself, with spam emerging as the mirror image of the online communities it targets. Brunton traces spam through three epochs: the 1970s to 1995, and the early, noncommercial computer networks that became the Internet; 1995 to 2003, with the dot-com boom, the rise of spam's entrepreneurs, and the first efforts at regulating spam; and 2003 to the present, with the war of algorithms—spam versus anti-spam. Spam shows us how technologies, from email to search engines, are transformed by unintended consequences and adaptations, and how online communities develop and invent governance for themselves.
