Abstract

A summary of brain theory is given so far as it is contained within the framework of Localization Theory. Difficulties of this "conventional theory" are traced back to a specific deficiency: there is no way to express relations between active cells (as for instance their representing parts of the same object). A new theory is proposed to cure this deficiency. It introduces a new kind of dynamical control, termed synaptic modulation, according to which synapses switch between a conducting and a non- conducting state. The dynamics of this variable is controlled on a fast time scale by correlations in the temporal fine structure of cellular signals. Furthermore, conventional synaptic plasticity is replaced by a refined version. Synaptic modulation and plasticity form the basis for short-term and long-term memory, respectively. Signal correlations, shaped by the variable network, express structure and relationships within objects. In particular, the figure-ground problem may be solved in this way. Synaptic modulation introduces exibility into cerebral networks which is necessary to solve the invariance problem. Since momentarily useless connections are deactivated, interference between di erent memory traces can be reduced, and memory capacity increased, in comparison with conventional associative memory

Abstract

The history of encyclopedias and wholly new forms of encyclopedias are briefly reviewed. The possibilities and problems that hypertext presents as a basis for new forms of encyclopedias are explored. The capabilities of current systems, both experimental and commercially available, are outlined, focusing on new possibilities for authoring and design and for reading the retrieval. Examples of applications already making use of hypertext are given.

Abstract

Hypertext uses a browsing rather than a searching strategy. Hypertext systems have found applications in a number of areas. They give users choice of information but this can prove a drawback. Examnines the effectiveness of hypertext as a way of retrieving information and reviews conventional information retrieval techniques. Considers previous attempts at combining information retrieval and hypertext and outlines a prototype systems developed to generate guided tours for users to direct them through hypertext to information they have requested. Discusses how adding this kind of itelligent guidance to a hypertext system would affect its usability as an information system

Abstract

Recent advances in the neurosciences have begun to elucidate how some fundamental mechanisms of nervous systems activity can explain human information processing and the acquisition of knowledge. Some of these findings are consistent with a cognitive view of constructivist models of learning and provide additional theoretical support for constructivist applications to science education reform. Current thought at the interface between neurocognitive research and constructivist philosophy is summarized here and discussed in a context of implications for scientific epistemology and conceptual change processes in science education

Abstract

Within dynamic organizations, information systems often fail to adapt to changing requirements and structures. The book presents a different view of IS provision, based on end-user information systems construction, as a means of avoiding many of the recognized problems. Adopting a philosophy of constructivism, emphasizing psychological and social factors in information construction, the authors examine different types of systems across natural and social sciences

Abstract

Purpose Belkin and Robertson (1976a) reflected on the ethical implications of theoretical research in information science and warned that there was potential for abuse of knowledge gained by undertaking such research and applying it to information systems. In particular, they identified the domains of advertising and political propaganda that posed particular problems. The purpose of this literature review is to revisit these ideas in the light of recent events in global information systems that demonstrate that their fears were justified. Design/methodology/approach The authors revisit the theory in information science that Belkin and Robertson used to build their argument, together with the discussion on ethics that resulted from this work in the late 1970s and early 1980s. The authors then review recent literature in the field of information systems, specifically information retrieval, social media and recommendation systems that highlight the problems identified by Belkin and Robertson. Findings Information science theories have been used in conjunction with empirical evidence gathered from user interactions that have been detrimental to both individuals and society. It is argued in the paper that the information science and systems communities should find ways to return control to the user wherever possible, and the ways to achieve this are considered. Research limitations/implications The ethical issues identified require a multidisciplinary approach with research in information science, computer science, information systems, business, sociology, psychology, journalism, government and politics, etc. required. This is too large a scope to deal with in a literature review, and we focus only on the design and implementation of information systems (Zimmer, 2008a) through an information science and information systems perspective. Practical implications The authors argue that information systems such as search technologies, social media applications and recommendation systems should be designed with the recipient of the information in mind (Paisley and Parker, 1965), not the sender of that information. Social implications Information systems designed ethically and with users in mind will go some way to addressing the ill effects typified by the problems for individuals and society evident in global information systems. Originality/value The authors synthesize the evidence from the literature to provide potential technological solutions to the ethical issues identified, with a set of recommendations to information systems designers and implementers.

Abstract

Anyone who has clarified a thought or prompted a response during a conversation by drawing a picture has exploited the potential of image making to convey information. Images are increasingly ubiquitous in daily communication due to advances in visually enabled information and communication technologies (ICT), such as information visualization applications, image retrieval systems, and virtual collaborative work tools. Although images are often used in social contexts, information science research concerned with the visual representation of information typically focuses on the image artifact and system building. To learn more about image making as a form of social interaction and as a form of information practice, a qualitative study examined face-to-face conversations involving the creation of ad hoc visualizations (i.e., "napkin drawings"). Interactional sociolinguistic concepts of conversational involvement and coordination guided multimodal analysis of video-recorded interactions that included spontaneous drawing. Findings show patterns in communicative activities associated with the visual representation of information. Furthermore, the activity of mark making contributes to the maintenance of conversational involvement in ways that are not always evident in the drawn artifact. This research has implications for the design and evaluation of visually enabled virtual collaboration environments, visual information extraction and retrieval systems, and data visualization tools.

Abstract

What we consider to be the influence of philosophy on scientific thinking largely depends on how science perceives itself. The understanding and conscious human-oriented design of the relationship between the computer and the creatively active person - i.e. the design of a formal model and the non-formal, natural and social environment - is always more readily recognized as the fundamental philosophical, theoretical and methodological problem of informatics (computer science and information systems). Informatics/computer science results from the necessity to overcome the tension between technology-based automation, which is based on a purely syntactic interpretation and transformation of information, and creative and active people who carry out semantic information processing based on their knowledge. It is this tension that requires the development and use of user-oriented software and the formal operations to be integrated into complex human work processes. Conceptual strategies that foster the development and integration of modern information technologies into social organization are currently the topic of vivid philosophical and methodological discussions, reflecting the influence of different philosophical schools. The utilization of information technologies has significantly changed both employee working conditions and the relationship between organizations and their environment. The development of humanity-oriented computer science is a necessary condition for integrating computational systems into social contexts and for largely adapting these systems to the users' needs.

Abstract

The idea of obtaining subject access to information by being able to visualize an information space, and to navigate through that space toward useful or interesting information, is attractive and plausible. However, this approach to subject access requires additional cognitive processing associated with the interaction of cognitive facilities that deal with concepts and those that deal with space. This additional cognitive processing may cause problems for users, particularly in dealing with the dimensions, the details, and the symbols of information space. Further, it seems likely that different cognitive abilities are associated with conceptual and spatial cognition. As a result, users who deal well with subject access using traditional conceptual approaches may experience difficulty in using visualization and navigation. An experiment designed to investigate the effects of different cognitive abilities on the use of both conceptual and spatial representations of information is outlined

Abstract

This volume has the virtue of airing a number of refreshing voices that are not often heard on this side of the Atlantic, and that bring perspectives that should energize our conversations about information in living systems." --Evelyn Fox Keller, MIT "Terzis and Arp have brought together an international array of experimental and theoretical scientists, philosophers, and cognitive scientists to explore the most consequential notion in modern biology--information. The notion is indispensable to molecular biology, and yet we have no idea how seriously we need to take it in that domain. The role of information is equally central to the origin and maintenance of life in a Second Law-driven world that destroys order. And the naturalization of information is the only bridge that can be crossed from cognitive psychology to neuroscience. All of these issues are faced squarely and accessibly in this important volume." --Alex Rosenberg, Duke University "Since the 1960s at least, it has become clear that we cannot content ourselves with describing living systems, and their life cycles, only in terms of matter and energy. An additional dimension--information--is the necessary complement. However, following an initial enthusiasm for an information-based approach to biology, conceptual developments and practical applications have been slow, to such an extent that doubts have eventually arisen, among biologists and philosophers alike, as to the real relevance, if not the legitimacy, of this approach. How profoundly ill-advised were those concerns is dramatically demonstrated by this excellent collection. Information and Living Systems provides a convincing and healthily fresh overview of this subject area in many of its ramifications, throughout the whole of biology." --Alessandro Minelli, University of Padova "Since the time of the discovery of the double-helical structure of DNA and its expression, scientists and philosophers have become increasingly aware that information is integral to the understanding of the organization of life--indeed, to the understanding of life. Information and Living Systems covers the gamut of issues--from the properties of the organism itself to epigenetic and evolutionary considerations to cognition, language, and personality. It transcends in scope and depth any available publications on bioinformation known to me. It is an important scholarly contribution that will interest professional biologists, philosophers, and information theorists, and will be very useful in courses for advanced undergraduate and graduate students.

Abstract

A great deal of information and knowledge is available in the form of full text, multimedia and other databases, as well as traditional information services. One of the issues of using information is to process meanings which are closely related with the sophisticated functiones such as learning, reasoning, inductive inference and problem solving. Automatic classification and intelligent access are straightforward applications and are useful when they are used togehter with thesauri and taxonomies which represent conceptual structures. Describes the basic principles and formulation of a new information model with flexible representation of meaning, and the direction of applications to advanced research of science and technology

Abstract

The literature of psychology, library science, management, computer science, and systems engineering is reviewed and integrated into an overall perspective of human information seeking and the design of information systems. The nature of information seeking is considered in terms of its role in decision making and problem solving, the dynamics of the process, and the value of information. Discussions of human information seeking focus on basic psychological studies, effects of cognitive style, and models of human behavior. Design issues considered include attributes of information systems, analysis of information needs, aids for information seeking, and evaluation of information systems
