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

Fundamental forms of information, as well as the term information itself, are defined and developed for the purposes of information science/studies. Concepts of natural and represented information (taking an unconventional sense of representation), encoded and embodied information, as well as experienced, enacted, expressed, embedded, recorded, and trace information are elaborated. The utility of these terms for the discipline is illustrated with examples from the study of information-seeking behavior and of information genres. Distinctions between the information and curatorial sciences with respect to their social (and informational) objects of study are briefly outlined.

Abstract

Addresses the issues of information seeking behaviour within the context of an information poor lifestyle, i.e. one in which the mass media are not viewed as providers of useful information and in which there is a parsimony of helpful interpersonal channels. Examines knowledge gap theory and concludes that, although the mass media are perceived as sources of information for some (the 'media rich'), they do not respond to the needs of the poor. Unfortunately, the role that interpersonal sources might play in this process have not been adequately addressed by knowledge gap researchers

Abstract

The emergence of Knowledge Management (KM) over the last decade has triggered the question how or even whether this new management discipline can be distinguished from the established field of Information Management (IM). In this paper we critically examine this demarcation issue from two angles. First we will investigate to what extent the difference between IM and KM can be anchored an a conceptual distinction between their respective objects: information and knowledge. After having shown that this widely adopted strategy promises little success, we will shift our attention to an examination of the fundamental objectives or guiding principles behind both disciplines. Seen from this angle we argue that KM in order to foster organizational learning, innovation and strategy flexibility, should adopt a postmodern epistemological perspective that is geared to the management of incommensurability and difference within and between organizations.

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

Abstract

A lack of structure, not the amount, is the reason for our growing inability to cope with information today. Through the advances in information technology, information has lost the connection with its carrier; therefore, the medium can no longer be used as a reliable indicator of information type. The classical methods of information handling are not sufficient for the growing amount and the new forms of information. In an information society, the individual needs a more comprehensive system of information management. The suggestion is to use 4 universal structuring dimensions - selection, time, hierarchy and sequence - and to apply them to information, regardless of the information carrier. Information producers, as well as information consumers, can use this tool-set to profit more fully from the growing mass of information

Abstract

The language and contents of the mass communications industry, and the products produced through and for commerical computerized information systems and networks, may appeal to relatively undeveloped aspects of our intellectual and spiritual faculties and could degrade rationalism and thus jeopardize the production of scientific knowledge. In particular, recent decades have seen a shift away from conceptual linguistic symbolism, historically used for scientific research and communication, to iconic symbolism and visual language, which may be poorly suited to scientific thought. Discusses the relationship between complex computing and telecommunications and both the content and the vehicles of learning and scientific research for the 21st century

Abstract

Inequities in information creation, production, distribution, and use are nothing new. Throughout human history some people have been more educated, better connected, more widely traveled, or more wellinformed than others. Until recently, relatively few have enjoyed the benefits of literacy, and even fewer could afford to own books. In the age of mass media, societies and social groups have varied dramatically in terms of their access to and uses of print, radio, television, film, telephone, and telegraph. What is new, however, is the growing attention being given to informational inequities in an increasingly information-driven global economy. Across disciplinary, national, and cultural boundaries, the widespread agreement is that the use of newer information and communication technologies (ICTs), particularly the Internet, has accelerated the production, circulation, and consumption of information in every form. But also a growing sense has arisen that ICTs have helped to exacerbate existing differences in information access and use, and may even have fostered new types of barriers. As Hess and Ostrom (2001, p. 45) point out, "Distributed digital technologies have the dual capacity to increase as well as restrict access to information."

Abstract

Critically examines claims for the use of information and communication technologies for the easy availability of information and so for the improvement of citizen participation in democratic processes. Examines the quality as opposed to the quantity of information available and discusses the nature of the information infrastructure as envisioned in the New Library: The People's Network report against the historical reality of the failure of established systems to fulfill their potential and the characteristics of the present information environment. Considers attacks on the established public library system and discusses the nature of official information as embodied in official statistics. Examines the commercialisation of broadcasting, the decline of public service broadcasting and the failure of radio and television to develop in private hands into vehicles for mass education, concluding that where quality of content is paramount for information purposes over techniques of presentation, the claims for technological solutions for the information age are overstated.

Content

"Overflowing inboxes, endlessly topped up by incoming emails. Constant alerts, notifications and text messages on your smartphone and computer. Infinitely scrolling streams of social-media posts. Access to all the music ever recorded, whenever you want it. And a deluge of high-quality television, with new series released every day on Netflix, Amazon Prime and elsewhere. The bounty of the internet is a marvellous thing, but the ever-expanding array of material can leave you feeling overwhelmed, constantly interrupted, unable to concentrate or worried that you are missing out or falling behind. No wonder some people are quitting social media, observing "digital sabbaths" when they unplug from the internet for a day, or buying old-fashioned mobile phones in an effort to avoid being swamped. This phenomenon may seem quintessentially modern, but it dates back centuries, as Ann Blair of Harvard University observes in "Too Much to Know", a history of information overload. Half a millennium ago, the printing press was to blame. "Is there anywhere on Earth exempt from these swarms of new books?" moaned Erasmus in 1525. New titles were appearing in such abundance, thousands every year. How could anyone figure out which ones were worth reading? Overwhelmed scholars across Europe worried that good ideas were being lost amid the deluge. Francisco Sanchez, a Spanish philosopher, complained in 1581 that 10m years was not long enough to read all the books in existence. The German polymath Gottfried Wilhelm Leibniz grumbled in 1680 of "that horrible mass of books which keeps on growing"."
