Rez. in: JASIST 53(2002) no.1, S.61-62 (E.G. Ackermann): "This brief summary cannot do justice to the intellectual depth, philosophical richness of the theoretical models, and their implications presented by Leydesdorff in his book. Next to this, the caveats presented earlier in this review are relatively minor. For all that, this book is not an "easy" read, nor is it for the theoretically or philosophically faint of heart. The content is certainly accessible to those with the interest and the stamina to see it through to the end, and would repay those who reread it with further insight and understanding. This book is recommended especially for the reader who is looking for a well-developed, general sociological theory of communication with a strong philosophical basis upon which to build a postmodern, deconstructionist research methodology"

Abstract

Although much of the hubris and hyperbole surrounding the 1990's Internet has softened to a reasonable level, the inexorable momentum of information growth continues unabated. This wealth of information provides resources for adapting to the problems posed by our increasingly complex world, but the simple availability of more information does not guarantee its successful transformation into valuable knowledge that shapes, guides, and improves our activity. When faced with something like the analysis of sense-making behavior on the web, traditional research models tell us a lot about learning and performance with browser operations, but very little about how people will actively navigate and search through information structures, what information they will choose to consume, and what conceptual models they will induce about the landscape of cyberspace. Thus, it is fortunate that a new field of research, Adaptive Information Interaction (AII), is becoming possible. AII centers on the problems of understanding and improving human-information interaction. It is about how people will best shape themselves to their information environments, and how information environments can best be shaped to people. Its roots lie in human-computer interaction (HCI), information retrieval, and the behavioral and social sciences. This book is about Information Foraging Theory (IFT), a new theory in Adaptive Information Interaction that is one example of a recent flourish of theories in adaptationist psychology that draw upon evolutionary-ecological theory in biology. IFT assumes that people (indeed, all organisms) are ecologically rational, and that human information-seeking mechanisms and strategies adapt the structure of the information environments in which they operate. Its main aim is to create technology that is better shaped to users. Information Foraging Theory will be of interest to student and professional researchers in HCI and cognitive psychology.

Rez. in: Mitteilungen VOEB 59(2006) H.4, S.74-76 (M. Katzmayr): "Information Literacy (IL) bzw. Informationskompetenz ist in aller Munde, wird sie doch als Schlüsselqualifikation angesehen, um an der so genannten Informationsgesellschaft teilzuhaben. Susie Andretta, Dozentin für Informationsmanagement an der London Metropolitan University, hat nun einen praxisorientierten Leitfaden zur IL vorgelegt, worin zwei Aspekte im Vordergrund stehen: einerseits die Vermittlung der IL in der universitären Lehre, womit andererseits auch ein erfolgreiches lebenslanges Lernen nach Verlassen der Universität ermöglicht werden soll. Das Buch beginnt mit einer theoretischen Einführung. Dort ist zu lesen, dass sich die Vermittlung von IL aus Kursen zur Bibliotheksbenutzung entwickelt habe - doch während letztere traditionell den effektiven Umgang mit Bibliotheksressourcen vermitteln und somit auf die Bibliothek beschränkt seien, beinhalte IL auch Herangehensweisen zur Lösung komplexer Problemstellungen. Drei prominente IL-Konzeptionen folgender Organisationen werden anschließend ausführlicher vorgestellt und verglichen: die der US-amerikanischen "Association of Colleges and Research Libraries" (ACRL), des "Australian and New Zealand Institute for information Literacy" (ANZIIL) und der britischen "Society of College, National and University Libraries" (SCONUL). In allen drei besteht IL zumindest aus dem Wahrnehmen eines Informationsbedarfes, Methoden zum Erhalt dieser Information und schließlich ihrer Bewertung, um die Fragen zu beantworten, die zum Informationsbedarf geführt haben. Alle drei gehen über die rein technologische Kompetenz (IT-Kompetenz) hinaus und umfassen u. a. Medien-, Bibliotheks-, und Recherchekompetenzen, um nur einige zu nennen. Allerdings gehen zwei dieser Konzeptionen noch wesentlich weiter - so fordert die ANZIIL von einer informationskompetenten Person u.a. folgende Fähigkeit: "the information-literate person applies prior and new information to construct new concepts or create new understandings" (S. 157), der Lernzielkatalog der SCONUL beinhaltet: "The ability to synthesise and build upon existing information, contributing to the creation of new knowledge" (S. 162).
Was hier auffällt, ist der äußerst weit reichende inhaltliche Anspruch dieser Sichtweise von IL. Inwieweit dadurch eine Abgrenzung zum Themenund Lehrgebiet des "wissenschaftlichen Arbeitens" bzw. zu den Charakteristika umfassender Bildung überhaupt noch sinnvoll möglich ist, wird von der Autorin leider nicht behandelt. Interessant ist der Stellenwert der Bibliotheken in der Lehre der IL: In allen drei Konzeptionen wird eine Kooperation zwischen Bibliothek und Wissenschaftsbetrieb empfohlen, ja erfolge die Vermittlung von IL idealiter im jeweiligen Fachstudium durch die problemlösungsorientierte Bearbeitung spezifischer Fragestellungen. So gesehen könne also nicht von einem Monopol der Bibliotheken ausgegangen werden, ihre Rolle sei vielmehr mit dem Motto "information literacy is an issue for the library but not of the library" (S. 53) angemessen umschrieben. In Großbritannien gehe dabei die Initiative meist von den Bibliotheken aus, in den USA und Australien eher vom Wissenschaftsbetrieb. In beiden Fällen funktioniere diese Partnerschaft aber nicht immer reibungslos. Die Beweggründe von Bibliotheken, sich hierzu engagieren, werden von der Autorin jedoch keiner tiefer gehenden Analyse unterzogen. Dies wurde vielleicht nicht völlig unbeabsichtigt unterlassen, da daran nämlich eine - im vorliegenden Werk ausgeblendete - grundsätzliche und weit verbreitete Kritik an der IL anknüpfen könnte. Ein Blick in die relevante Literatur zeigt nämlich, dass Bibliothekarinnen nicht nur hehre Motive zugeschrieben werden, wenn sie sich am IL-Hype beteiligen bzw. ihn vorantreiben. Neben Erfahrungen mit der dürftigen Informationskompetenz vieler Studierender werden ihnen auch ganz andere, pragmatischere Beweggründe zugedacht'. Ein Beispiel: Die zunehmende institutionelle Marginalisierung von Bibliotheken und ihren Mitarbeiterinnen im Universitätsbetrieb mag eine kreative Vorwärtsverteidigung unter dem Deckmantel der IL als zweckmäßig erscheinen lassen' - überspitzt formuliert: IL als Konstrukt oder zumindest willkommene Gelegenheit, um den Bibliotheken auch weiterhin eine zentrale Rolle an den Universitäten zu sichern. Zum Glück gelingt es Andretta, anhand der relevanten Literatur und eigener Erfahrungen als Dozentin plausibel zu argumentieren, dass der Mangel vieler Studierender an Informationskompetenz tatsächlich eklatant und somit ein Handlungsbedarf gegeben ist. Welche Motive die Bibliotheken hier sonst noch haben mögen, kann so gesehen ruhig im Dunkeln bleiben.

Rez. in: Spektrum der Wissenschaft. 2004, H.11., S.92-96 (S. Stier): "Nach Einsteins Allgemeiner Relativitätstheorie gibt es im Kosmos Objekte von so ungeheurer Gravitationskraft, dass aus ihrem Inneren keinerlei Informationen, auch nicht in Form von Licht, nach außen dringen können; sie werden deshalb als Schwarze Löcher bezeichnet. Eines der vielen Rätsel, die sie umgeben, war lange Zeit die Größe ihrer Entropie (siehe »Das holografische Universum« von Jacob Bekenstein, Spektrum der Wissenschaft 11/ 2003, S. 34). Nach der herkömmlichen Definition ist die Entropie ein Maß für den Informationsgehalt eines Objekts; sie berechnet sich aus der Zahl seiner inneren Zustände, in denen es dieselben Eigenschaften hat. Damit hängt sie davon ab, welche Eigenschaften man zur Beschreibung des Objekts wählt und wie detailliert man seine inneren Zustände beschreibt. Entropie und Information sind also relative, vom Kontext einer bestimmten Beschreibung abhängige Maße. je detaillierter die Beschreibung seiner inneren Zustände, desto größer die Entropie. Nicht so bei einem Schwarzen Loch: Da es alle Informationen über sein Inneres verbirgt, ist seine Entropie die Obergrenze für alles, was man überhaupt darüber wissen könnte, unabhängig von irgendwelchen Modellen seiner Struktur. Information wird damit zu einer unabhängigen Eigenschaft eines Objekts und zu einer absoluten physikalischen Größe. Das ist ein radikaler Bruch im Verständnis von Information. Mit Hilfe der von Bekenstein vor dreißig Jahren angegebenen Formel kann man berechnen, wie die Entropie eines Schwarzen Lochs von der Größe unseres Universums dadurch zunimmt, dass von außen ein Proton hineinstürzt. Diese Änderung lässt sich als der Informationsgehalt des Protons selbst interpretieren: Es sind 10**40 Bit, ein Wert, der im Rahmen der etablierten Physik eigentlich nicht erklärbar ist.

Rez. in: Spektrum der Wissenschaft. 2005, H.12, S.106-107 (M. Jäger): "Das Buch gehört in eine Reihe mit »eBay Hacks«, »Google Hacks« und »Mac OS X Hacks« aus demselben Verlag: Anleitungen, ein System etwas anders zu nutzen, als sein Anbieter das vorgesehen hat. Und doch fällt es aus dem Rahmen. Kein Computer oder Betriebssystem wird gehackt, sondern das Gehirn. Wie die anderen »Hack«Bücher ist es nicht als Sachbuch im herkömmlichen Sinn angelegt, sondern als Sammlung von hundert Experimenten, »Hacks«, aus zehn verschiedenen Bereichen. Gezeigt werden erstaunliche Selbstversuche, unter anderem zum visuellen System, zu Aufmerksamkeitssteuerung, Hören und Sprache, Bewegung, Erinnerung, Schlussfolgerung und Gestaltwahrnehmung. Jedes neurologische Phänomen wird zunächst allgemein erläutert; es folgen die Beschreibung eines zugehörigen Experiments und eine kurze Erklärung sowie Angaben zu weiterführenden Texten und Internetlinks. Tom Stafford, Psychologe an der Universität Sheffield (England), und Matt Webb, Ingenieur, Designer und freischaffender Autor, unter anderem für die BBC, wurden von Spezialisten auf dem jeweiligen Gebiet unterstützt. Die einst beliebte Metapher vom Gehirn als Computer ist in der ursprünglichen Form nicht mehr haltbar, wie auch die Autoren im Vorwort einräumen. Dafür haben sich in den letzten Jahrzehnten zu viele und wesentliche Differenzen offenbart, etwa was Speicherung und Verarbeitung von Informationen angeht. Dennoch gibt es hinreichend viele Parallelen, um die Verwendung des Begriffs »Hack« zu rechtfertigen.

It is important to understand the origins of Kuhlthau's ideas in the work of the educational theorists, Dewey, Kelly and Bruner. Putting the matter in a rather simplistic manner, Dewey identified stages of cognition, Kelly attached the idea of feelings being associated with cognitive stages, and Bruner added the notion of actions associated with both. We can see this framework underlying Kuhlthau's research in her description of the actions undertaken at different stages in the search process and the associated feelings. Central to the transfer of these ideas to practice is the notion of the 'Zone of Intervention' or the point at which an information seeker can proceed more effectively with assistance than without. Kuhlthau identifies five intervention zones, the first of which involves intervention by the information seeker him/herself. The remaining four involve interventions of different kinds, which the author distinguishes according to the level of mediation required: zone 2 involves the librarian as 'locater', i.e., providing the quick reference response; zone 3, as 'identifier', i.e., discovering potentially useful information resources, but taking no further interest in the user; zone 4 as 'advisor', i.e., not only identifying possibly helpful resources, but guiding the user through them, and zone 5 as 'counsellor', which might be seen as a more intensive version of the advisor, guiding not simply on the sources, but also on the overall process, through a continuing interaction with the user. Clearly, these processes can be used in workshops, conference presentations and the classroom to sensitise the practioner and the student to the range of helping strategies that ought to be made available to the information seeker. However, the author goes further, identifying a further set of strategies for intervening in the search process, which she describes as 'collaborating', 'continuing', 'choosing', 'charting', 'conversing' and 'composing'. 'Collaboration' clearly involves the participation of others - fellow students, work peers, fellow researchers, or whatever, in the search process; 'continuing' intervention is associated with information seeking that involves a succession of actions - the intermediary 'stays with' the searcher throughout the process, available as needed to support him/her; 'choosing', that is, enabling the information seeker to identify the available choices in any given situation; 'charting' involves presenting a graphic illustration of the overall process and locating the information seeker in that chart; 'conversing' is the encouragement of discussion about the problem(s), and 'composing' involves the librarian as counsellor in encouraging the information seeker to document his/her experience, perhaps by keeping a diary of the process.

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.

Rez. in: Mitt. VÖB 59(2006) H.2, S.81-83 (O. Oberhauser): "Mit diesem Band haben zwei herausragende Vertreter der europäischen Informationswissenschaft, die Professoren Peter Ingwersen (Kopenhagen) und Kalervo Järvelin (Tampere) ein Werk vorgelegt, das man vielleicht dereinst als ihr opus magnum bezeichnen wird. Mich würde dies nicht überraschen, denn die Autoren unternehmen hier den ambitionierten Versuch, zwei informations wissenschaftliche Forschungstraditionen, die einander bisher in eher geringem Ausmass begegneten, unter einem gesamtheitlichen kognitiven Ansatz zu vereinen - das primär im sozialwissenschaftlichen Bereich verankerte Forschungsgebiet "Information Seeking and Retrieval" (IS&R) und das vorwiegend im Informatikbereich angesiedelte "Information Retrieval" (IR). Dabei geht es ihnen auch darum, den seit etlichen Jahren zwar dominierenden, aber auch als zu individualistisch kritisierten kognitiven Ansatz so zu erweitern, dass technologische, verhaltensbezogene und kooperative Aspekte in kohärenter Weise berücksichtigt werden. Dies geschieht auf folgende Weise in neun Kapiteln: - Zunächst werden die beiden "Lager" - die an Systemen und Laborexperimenten orientierte IR-Tradition und die an Benutzerfragen orientierte IS&R-Fraktion - einander gegenübergestellt und einige zentrale Begriffe geklärt. - Im zweiten Kapitel erfolgt eine ausführliche Darstellung der kognitiven Richtung der Informationswissenschaft, insbesondere hinsichtlich des Informationsbegriffes. - Daran schliesst sich ein Überblick über die bisherige Forschung zu "Information Seeking" (IS) - eine äusserst brauchbare Einführung in die Forschungsfragen und Modelle, die Forschungsmethodik sowie die in diesem Bereich offenen Fragen, z.B. die aufgrund der einseitigen Ausrichtung des Blickwinkels auf den Benutzer mangelnde Betrachtung der Benutzer-System-Interaktion. - In analoger Weise wird im vierten Kapitel die systemorientierte IRForschung in einem konzentrierten Überblick vorgestellt, in dem es sowohl um das "Labormodell" als auch Ansätze wie die Verarbeitung natürlicher Sprache und Expertensysteme geht. Aspekte wie Relevanz, Anfragemodifikation und Performanzmessung werden ebenso angesprochen wie die Methodik - von den ersten Laborexperimenten bis zu TREC und darüber hinaus.

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.
