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

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

Describes the methodology and reports the results of a study to measure text comprehension by school students when using a variety of media. Four different texts in the printed multi volume Compton's Encyclopedia and its multimedia CD-ROM database equivalent were read by grade 6 (11-12 year old) students who were then asked several multiple choice questions on them. Three groups, print, text on screen and multimedia (text, illustration and video), were asked only to read the texts presented to them. Two additional groups, print and multimedia CD-ROM, had to retrieve the texts before reading them. No significant main effect was found for multimedia over print or text on screen. However, a significant interaction was found between the use of multimedia and text complexity. Boys were found to cope markedly better with multimedia CD-ROM, a finding which was not expected and ran counter to the results of previous studies

Abstract

Tests were carried out on 120 grade 6 students to compare Compton's Multimedia Encyclopedia on CD-ROM and its printe equivalent in terms of students' ability to recall information and to draw inferences from it. Between-subject varaibles were 3 presentation conditions (printed text with illustrations, text-on-screen, and multimedia-text, still images, and animation) and a retrieval condition (topic retrieved before viewing / topic presented without retrieval). Within-subject variables were text complexity (complex or simple), text type (descriptive or procedural), and measure (propositions recalled versus propositions inferred). Presentation conditions produced no significant main effect although text-on-screen resulted in somewhat higher recall and multimedia resulted in somewhat higher inference scores. Multimedia had the greatest effect in the case of simple topics, and especially the simple procedural topic

Abstract

An exploratory study was conducted of elementary school children searching a full-text electronic encyclopedia on CD-ROM. 28 third and forth graders and 24 sixth graders conducted 2 assigned searches, one open-ended, the other one closed, after 2 demonstration sessions. Keystrokes captured by the computer and observer notes were used to examine user information-seeking strategies from a mental model perspective. Older searchers were more successful in finding required information, and took less time than younger searchers. No differences in total number of moves were found. Analysis of search patterns showed that novices used a heuristic, highly interactive search strategy. Searchers used sentence and phrase queries, indicating unique mental models for this search system. Most searchers accepted system defaults and used the AND connective in formulating queries. Transition matrix analysis showed that younger searchers generally favoured query refining moves and older searchers fovoured examining title and text moves. Suggestions for system designers were made and future research questions were identified
