Metamodeling for Method Engineering
by Manfred Jeusfeld Matthias Jarke John MylopoulosThis text is a guide to the foundations of method engineering, a developing field concerned with the definition of techniques for designing software systems. The approach is based on metamodeling, the construction of a model about a collection of other models. The book applies the metamodeling approach in five case studies, each describing a solution to a problem in a specific domain. Suitable for classroom use, the book is also useful as a reference for practitioners. The book first presents the theoretical basis of metamodeling for method engineering, discussing information modeling, the potential of metamodeling for software systems development, and the introduction of the metamodeling tool ConceptBase. The second, and larger, portion of the book reports on applications of the metamodeling approach to method engineering. These detailed case studies range from telecommunication service specification, hypermedia design, and data warehousing to cooperative requirements engineering, chemical device modeling, and design of new abstraction principles of modeling languages. Although these chapters can stand alone as case studies, they also relate to the earlier theoretical chapters. The metamodeling approach described in the book is based on the Telos metamodeling language implemented by the ConceptBase system. An accompanying CD-ROM contains the ConceptBase system and a large collection of Telos metamodels discussed in the text. The CD-ROM enables readers to start directly with method engineering, from small method chunks up to complete method definitions. The complete definition of Ed Yourdon's structured analysis method is included as an instructional example.

By using metaphors as a mental model, Weller enables educators to move beyond pragmatic concerns into more imaginative and playful uses of technology and to critically examine the appropriate implementation and adoption of ed tech.
The Metaphysics of Technology (Routledge Studies in Social and Political Thought #94)
by David SkrbinaWhat is technology? Why does it have such power in our lives? Why does it seemingly progress of its own accord, and without regard to social or environmental well-being? The quest for the essence of technology is an old one, with roots in the pre-Socratic philosophy of ancient Greece. It was then that certain thinkers first joined the ideas of technê and logos into a single worldview. The Greeks saw it as a kind of world-force, present in both the works of men and in nature itself. It was the very creative power of the cosmos. In the 20th century, German thinkers like Dessauer, Juenger, and Heidegger sought the metaphysical basis of technology, with varying success. French theologian Jacques Ellul argued persuasively that technology was an autonomous force of nature that determined all aspects of human existence, but he neglected the metaphysical underpinnings. Recent writers in the philosophy of technology have generally eschewed metaphysics altogether, preferring to concentrate on constructivist models or pragmatic analyses. In the present work, Skrbina returns to a classic metaphysical approach, seeking not so much an essence of technology but rather a deep and penetrating analysis of the entire technological phenomenon. Drawing on the Greeks, he argues for a teleological metaphysics in which increasing order in the universe is itself defined as a technological process. On this reading, all of reality constitutes a technical sphere, a "pantechnikon," of universal scope. This work — the first-ever book-length treatment of the topic — breaks new ground by providing an in-depth and critical study of the metaphysics of technology, as well as drawing out the practical consequences. Technology poses significant risks to humanity and the planet, risks that can be mitigated through a detailed philosophical analysis.

The Metaverse: And How It Will Revolutionize Everything
by Matthew BallINTERNATIONAL BESTSELLER — United States, Canada, United Kingdom, and China (Wall Street Journal, Associated Press, Nielsen Bookscan, Publishers Weekly, USA Today, Toronto Star, Globe & Mail, BookNet Canada, Bookseller.com, Bookdao/Nielsen, JD, DangDang) Tim Sweeney (CEO of Fortnite-maker Epic Games): “Matthew Ball’s essays have defined, analyzed, and inspired the Metaverse for years. His book is an approachable and essential guide to the strategic, technical, and philosophical foundations of this new medium.” Derek Thompson (Atlantic staff writer and national best-selling author of Hit Makers): “This book feels like a rare achievement: a definitive statement about an emerging phenomenon that could shape the digital world, the global economy, and the very experience of human consciousness.” From the leading theorist of the Metaverse comes the definitive account of the next internet: what the Metaverse is, what it will take to build it, and what it means for all of us. The term “Metaverse” is suddenly everywhere, from the front pages of national newspapers and the latest fashion trends to the plans of the most powerful companies in history. It is already shaping the policy platforms of the US government, the European Union, and the Chinese Communist Party. But what, exactly, is the Metaverse? As pioneering theorist and venture capitalist Matthew Ball explains, it is a persistent and interconnected network of 3D virtual worlds that will eventually serve as the gateway to most online experiences, and also underpin much of the physical world. For decades, these ideas have been limited to science fiction and video games, but they are now poised to revolutionize every industry and function, from finance and healthcare to education, consumer products, city planning, dating, and well beyond. Taking us on an expansive tour of the “next internet,” Ball demonstrates that many proto-Metaverses are already here, such as Fortnite, Minecraft, and Roblox. Yet these offer only a glimpse of what is to come. Ball presents a comprehensive definition of the Metaverse before explaining the technologies that will power it—and the breakthroughs that will be necessary to fully realize it. He addresses the governance challenges the Metaverse entails; investigates the role of Web3, blockchains, and NFTs; and predicts Metaverse winners and losers. Most importantly, he examines many of the Metaverse’s almost unlimited applications. The internet will no longer be at arm’s length; instead, it will surround us, with much of our lives, labor, and leisure taking place inside the Metaverse. Bringing clarity and authority to a frequently misunderstood concept, Ball foresees trillions of dollars in new value—and the radical reshaping of society.
