Abstract

Aufgrund der so großen Bedeutung von Privatheit im Internet hat acatech, die Deutsche Akademie der Technikwissenschaften, 2011 ein Projekt initiiert, das sich mit dem Privatheitsparadoxon wissenschaftlich auseinandersetzt. In dem Projekt werden Empfehlungen entwickelt, wie sich eine Kultur der Privatheit und des Vertrauens im Internet etablieren lässt, die es ermöglicht, das Paradoxon aufzulösen. Wir verwenden hier den Begriff der Privatheit. Er deutet an, dass hier nicht nur der räumliche Begriff Privatsphäre gemeint ist, sondern auch das im europäischen Kontext wichtige Konzept der informationellen Selbstbestimmung einbezogen ist. Dieser Band legt die Ergebnisse der ersten Projektphase vor: eine Bestandsaufnahme von Privatheit im Internet aus verschiedenen Blickwinkeln. Kapitel 1 stellt die Wünsche und Befürchtungen von Internetnutzern und Gesellschaft im Hinblick auf ihre Privatheit vor. Sie wurden mithilfe sozialwissenschaftlicher Methoden untersucht. Ergänzend dazu untersucht das zweite Kapitel Privatheit im Cyberspace aus ethischer Perspektive. Das dritte Kapitel widmet sich ökonomischen Aspekten: Da viele Onlinedienstleistungen mit Nutzerdaten bezahlt werden, ergibt sich die Frage, was dies sowohl für den Nutzer und Kunden als auch für die Unternehmen bedeutet. Kapitel 4 hat einen technologischen Fokus und analysiert, wie Privatheit von Internettechnologien bedroht wird und welche technischen Möglichkeiten es gibt, um die Privatheit des Nutzers zu schützen. Selbstverständlich ist der Schutz von Privatheit im Internet nicht nur ein technisches Problem. Deshalb untersucht Kapitel 5 Privatheit aus rechtlicher Sicht. Bei der Lektüre der fünf Kapitel wird dem Leser sofort die Komplexität der Frage von Privatheit im Internet (Internet Privacy) bewusst. Daraus folgt die unbedingte Notwendigkeit eines interdisziplinären Ansatzes. In diesem Sinne wird die interdisziplinäre Projektgruppe gemeinsam Optionen und Empfehlungen für einen Umgang mit Privatheit im Internet entwickeln, die eine Kultur der Privatheit und des Vertrauens im Internet fördern. Diese Optionen und Empfehlungen werden 2013 als zweiter Band dieser Studie veröffentlicht.

Abstract

Examines the changes which have taken place in recent years to give rise to what may be identified as the information society. Treats the subject by considering 4 aspects: the historical dimension (script to print, mass media and new technology); the economic dimension (information marketplace and access to information); the political dimension (information rich and information poor, information, the state and the citizen) and the information profession

Rez. in: JASIST 56(2005) no.10, S.1126-1128 (P.K. Nayar): "How Images Think is an exercise both in philosophical meditation and critical theorizing about media, images, affects, and cognition. Burnett combines the insights of neuroscience with theories of cognition and the computer sciences. He argues that contemporary metaphors - biological or mechanical - about either cognition, images, or computer intelligence severely limit our understanding of the image. He suggests in his introduction that "image" refers to the "complex set of interactions that constitute everyday life in image-worlds" (p. xviii). For Burnett the fact that increasing amounts of intelligence are being programmed into technologies and devices that use images as their main form of interaction and communication-computers, for instance-suggests that images are interfaces, structuring interaction, people, and the environment they share. New technologies are not simply extensions of human abilities and needs-they literally enlarge cultural and social preconceptions of the relationship between body and mind. The flow of information today is part of a continuum, with exceptional events standing as punctuation marks. This flow connects a variety of sources, some of which are continuous - available 24 hours - or "live" and radically alters issues of memory and history. Television and the Internet, notes Burnett, are not simply a simulated world-they are the world, and the distinctions between "natural" and "non-natural" have disappeared. Increasingly, we immerse ourselves in the image, as if we are there. We rarely become conscious of the fact that we are watching images of events-for all perceptioe, cognitive, and interpretive purposes, the image is the event for us. The proximity and distance of viewer from/with the viewed has altered so significantly that the screen is us. However, this is not to suggest that we are simply passive consumers of images. As Burnett points out, painstakingly, issues of creativity are involved in the process of visualization-viewwes generate what they see in the images. This involves the historical moment of viewing-such as viewing images of the WTC bombings-and the act of re-imagining. As Burnett puts it, "the questions about what is pictured and what is real have to do with vantage points [of the viewer] and not necessarily what is in the image" (p. 26). In his second chapter Burnett moves an to a discussion of "imagescapes." Analyzing the analogue-digital programming of images, Burnett uses the concept of "reverie" to describe the viewing experience. The reverie is a "giving in" to the viewing experience, a "state" in which conscious ("I am sitting down an this sofa to watch TV") and unconscious (pleasure, pain, anxiety) processes interact. Meaning emerges in the not-always easy or "clean" process of hybridization. This "enhances" the thinking process beyond the boundaries of either image or subject. Hybridization is the space of intelligence, exchange, and communication.
The sixth chapter looks at this interfacing of humans and machines and begins with a series of questions. The crucial one, to my mind, is this: "Does the distinction between humans and technology contribute to a lack of understanding of the continuous interrelationship and interdependence that exists between humans and all of their creations?" (p. 125) Burnett suggests that to use biological or mechanical views of the computer/mind (the computer as an input/output device) Limits our understanding of the ways in which we interact with machines. He thus points to the role of language, the conversations (including the one we held with machines when we were children) that seem to suggest a wholly different kind of relationship. Peer-to-peer communication (P2P), which is arguably the most widely used exchange mode of images today, is the subject of chapter seven. The issue here is whether P2P affects community building or community destruction. Burnett argues that the trope of community can be used to explore the flow of historical events that make up a continuum-from 17th-century letter writing to e-mail. In the new media-and Burnett uses the example of popular music which can be sampled, and reedited to create new compositions - the interpretive space is more flexible. Private networks can be set up, and the process of information retrieval (about which Burnett has already expended considerable space in the early chapters) involves a lot more of visualization. P2P networks, as Burnett points out, are about information management. They are about the harmony between machines and humans, and constitute a new ecology of communications. Turning to computer games, Burnett looks at the processes of interaction, experience, and reconstruction in simulated artificial life worlds, animations, and video images. For Burnett (like Andrew Darley, 2000 and Richard Doyle, 2003) the interactivity of the new media games suggests a greater degree of engagement with imageworlds. Today many facets of looking, listening, and gazing can be turned into aesthetic forms with the new media. Digital technology literally reanimates the world, as Burnett demonstrates in bis concluding chapter. Burnett concludes that images no longer simply represent the world-they shape our very interaction with it; they become the foundation for our understanding the spaces, places, and historical moments that we inhabit. Burnett concludes his book with the suggestion that intelligence is now a distributed phenomenon (here closely paralleling Katherine Hayles' argument that subjectivity is dispersed through the cybernetic circuit, 1999). There is no one center of information or knowledge. Intersections of human creativity, work, and connectivity "spread" (Burnett's term) "intelligence through the use of mediated devices and images, as well as sounds" (p. 221).
Burnett's work is a useful basic primer an the new media. One of the chief attractions here is his clear language, devoid of the jargon of either computer sciences or advanced critical theory. This makes How Images Think an accessible introduction to digital cultures. Burnett explores the impact of the new technologies an not just image-making but an image-effects, and the ways in which images constitute our ecologies of identity, communication, and subject-hood. While some of the sections seem a little too basic (especially where he speaks about the ways in which we constitute an object as an object of art, see above), especially in the wake of reception theory, it still remains a starting point for those interested in cultural studies of the new media. The Gase Burnett makes out for the transformation of the ways in which we look at images has been strengthened by his attention to the history of this transformation-from photography through television and cinema and now to immersive virtual reality systems. Joseph Koemer (2004) has pointed out that the iconoclasm of early modern Europe actually demonstrates how idolatory was integral to the image-breakers' core belief. As Koerner puts it, "images never go away ... they persist and function by being perpetually destroyed" (p. 12). Burnett, likewise, argues that images in new media are reformed to suit new contexts of meaning-production-even when they appear to be destroyed. Images are recast, and the degree of their realism (or fantasy) heightened or diminished-but they do not "go away." Images do think, but-if I can parse Burnett's entire work-they think with, through, and in human intelligence, emotions, and intuitions. Images are uncanny-they are both us and not-us, ours and not-ours. There is, surprisingly, one factual error. Burnett claims that Myron Kreuger pioneered the term "virtual reality." To the best of my knowledge, it was Jaron Lanier who did so (see Featherstone & Burrows, 1998 [1995], p. 5)."

Rez. in: JASIST 56(2005) no.9, S.1008-1009 (D.E. Agosto): "This second edition of Information Literacy: Essential Skills for the Information Age remains true to the first edition (published in 1998). The main changes involved the updating of educational standards discussed in the text, as well as the updating of the term history. Overall, this book serves as a detailed definition of the concept of information literacy and focuses heavily an presenting and discussing related state and national educational standards and policies. It is divided into 10 chapters, many of which contain examples of U.S. and international information literacy programs in a variety of educational settings. Chapter one offers a detailed definition of information literacy, as well as tracing the deviation of the term. The term was first introduced in 1974 by Paul Zurkowski in a proposal to the national Commission an Libraries and Information Science. Fifteen years later a special ALA committee derived the now generally accepted definition: "To be information literate requires a new set of skills. These include how to locate and use information needed for problem-solving and decision-making efficiently and effectively" (American Library Association, 1989, p. 11). Definitions for a number of related concepts are also offered, including definitions for visual literacy, media literacy, computer literacy, digital literacy, and network literacy. Although the authors do define these different subtypes of information literacy, they sidestep the argument over the definition of the more general term literacy, consequently avoiding the controversy over national and world illiteracy rates. Regardless of the actual rate of U.S. literacy (which varies radically with each different definition of "literacy"), basic literacy, i.e., basic reading and writing skills, still presents a formidable educational goal in the U.S. In fact, More than 5 million high-schoolers do not read well enough to understand their textbooks or other material written for their grade level. According to the National Assessment of Educational Progress, 26% of these students cannot read material many of us world deem essential for daily living, such as road signs, newspapers, and bus schedules. (Hock & Deshler, 2003, p. 27)
Lastly, chapter 10 considers possible future directions of the information literacy movement. The authors conclude "Our ability to be information literate depends an our willingness to be lifelong learners as we are challenged to master new, and as yet unknown, technologies that will surely alter the landscape of information in the future" (p. 177). Following the book's 10 chapters are a number of appendices that present information literacy standards and definitions, a timeline of the evolution of the information literacy movement, and a number of related bibliographies. Lead author Eisenberg is perhaps best known as the co-creator, with Bob Berkowitz, of the Big 6, an information literacy model. The model includes six components: Task Definition, Information Seeking Strategies, Location and Access, Use of Information, Synthesis, and Evaluation (Eisenberg, 2003). Throughout the book, Eisenberg and his co-authors show how the Big 6 model can be used to teach information literacy. For example, in chapter nine, "Technology and Information Literacy," they lay out each of the six model components, providing specific technological skills benchmarks for each, such as "Know the roles and computer expertise of the people working in the school library media center and elsewhere who might provide information or assistance" under step 3, "Location and Access" (p. 160). The many detailed descriptions of information literacy policies and programs that appear throughout the book make it most useful for educators, administrators, and policy makers involved in the teaching, planning, and development of information literacy programs, standards, and policies. Overall, this newly revised volume stands as one of the most comprehensive single available sources from which to begin a detailed investigation of the concept of information literacy."

Zu genau diesem Ergebnis war schon einige Jahre zuvor Carl Friedrich von Weizsäcker auf völlig anderem Weg gekommen. Die von ihm entwickelte Urtheorie ist der radikale Versuch, die gesamte Naturwissenschaft, mit der Quantentheorie an der Spitze, auf den Informationsbegriff zurückzuführen: Ure sind nichts weiter als die Quantenbits (»Qubits«), die im Zusammenhang mit den Quantencomputern zu Ehren gekommen sind. Dabei setzt die Urtheorie nicht einmal die Struktur des Raumes voraus; diese ergibt sich erst aus der Verknüpfung der kleinsten Informationseinheit, der Entscheidung zwischen zwei Möglichkeiten, und der Quantentheorie. Bis heute ist die Urtheorie ein Fragment geblieben; so ist es nicht gelungen, eine Theorie der Wechselwirkung der Ure zu entwickeln, die schließlich zu einer Theorie der Elementarteilchen führen sollte. Der vorliegende Sammelband ist von Weizsäcker zu seinem 90. Geburtstag gewidmet; die sehr wenigen Forscher, die an der Urtheorie weitergearbeitet haben, kommen in mehreren Beiträgen zu Wort. Der Frankfurter Physiker Thomas Görnitz fasst seine eigenen einschlägigen Arbeiten zusammen. Dazu gehört die oben genannte Verknüpfung der Entropie Schwarzer Löcher mit der Urtheorie, die für Görnitz die »zentrale Anbindung« an die etablierte Physik ist. Ausgehend von den heute bekannten Größenordnungen für Radius und Dichte des Universums kommt er zu Abschätzungen für die Entropie des gesamten Universums und die Anzahl der darin enthaltenen Nukleonen und Photonen, die nach seiner Aussage mit den empirisch bekannten Daten gut übereinstimmen. Das gelte auch für die Energie der Photonen im Universum, der so genannten » kosmischen Hintergrundstrahlung«. Die Verknüpfung der Urtheorie mit der Allgemeinen Relativitätstheorie führe zu einem plausiblen kosmologischen Modell, in dem sich die extreme Kleinheit der »kosmologischen Konstanten«, der Vakuumenergie des Kosmos, in natürlicher Weise ergebe. Für die etablierten Theorien stelle dies ein erhebliches Problem dar.

Rez. in: Information Research, 9(3), review no. R129 (T.D. Wilson): "The first edition of this book was published ten years ago and rapidly become something of a classic in the field of information seeking behaviour. It is good to see the second edition which incorporates not only the work the author has done since 1993, but also related work by other researchers. Kuhlthau is one of the most cited authors in the field and her model of the information search process, involving stages in the search and associated feelings, has been used by others in a variety of contexts. However, what makes this book different (as was the case with the first edition) is the author's dedication to the field of practice and the book's sub-title demonstrates her commitment to the transfer of research. In Kuhlthau's case this is the practice of the school library media specialist, but her research has covered students of various ages as well as a wide range of occupational groups. Because the information search model is so well known, I shall concentrate in this review on the relationship between the research findings and practice. It is necessary, however, to begin with the search process model, because this is central. Briefly, the model proposes that the searcher goes through the stages of initiation, selection, exploration, formulation, collection and presentation, and, at each stage, experiences various feelings ranging from optimism and satisfaction to confusion and disappointment. Personally, I occasionally suffer despair, but perhaps that is too extreme for most!
