- 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
- Describes an approach to the problem of object recognition structured around a sequence of increasingly specialised grouping activities that assemble coherent regions of images that can be sown to satisfy increasingly stringent conditions. The recognition system is designed to cope with: colour and texture; the ability to deal with general objects in uncontrolled configurations and contexts; and a satisfactory notion of classification. These properties are illustrated using 3 case studies, demonstrating: the use of descriptions that fuse colour and spatial properties; the use of fusion of texture and geometric properties to describes trees; and the use of a recognition system to determine accurately whether an image contains people and animals

- Abstract
- The General Motors Media Archives (GMMA) project is undertaking one of the largest digitization efforts in the world. GMMA houses over 3 million still photographic images and tens of thousands of motion picture films and videos spanning over a hundred years. The images are a rich history of the evolution of transport, urban growth, fashion, design, and popular culture. GMMA has developed a layered approach to visual indexing that dissects the objects, style and implication of each image, so that the indexing system can accomodate all potential approaches to the material. Explains each layer of indexing and provides examples which show implication layers that can easily be missed

- Abstract
- Although classification has been an important aspect of astronomy since stellar spectroscopy in the late nineteenth century, to date no comprehensive classification system has existed for all classes of objects in the universe. Here we present such a system, and lay out its foundational definitions and principles. The system consists of the "Three Kingdoms" of planets, stars and galaxies, eighteen families, and eighty-two classes of objects. Gravitation is the defining organizing principle for the families and classes, and the physical nature of the objects is the defining characteristic of the classes. The system should prove useful for both scientific and pedagogical purposes.

- 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
- Texas A&M University Libraries developed a Web-based training (WBT) application for LandView III, a federal depository CD-ROM publication using cross-browser dynamic HTML (DHTML) and other Web technologies. The interactive and self-paced tutorial demonstrates the major features of the CD-ROM and shows how to navigate the programs. The tutorial features dynamic HTML techniques, such as hiding, showing and moving layers; dragging objects; and windows-style drop-down menus. It also integrates interactive forms, common gateway interface (CGI), frames, and animated GIF images in the design of the WBT. After describing the design and implementation of the tutorial project, an evaluation of usage statistics and user feedback was conducted, as well as an assessment of its strengths and weaknesses, and a comparison of this tutorial with other common types of training methods. The present article describes an innovative approach for CD-ROM training using advanced Web technologies such as dynamic HTML, which can simulate and demonstrate the interactive use of the CD-ROM, as well as the actual search process of a database.

- Content
- The delivery of learning objects, small chunks of stand alone core components of reusable instruction (Nugent 2005) are used extensively in k-12 environments. Learning objects are videos and animated clips which are deployed in classrooms through public television companion websites. One such site is PBS. org/teachersource. Scholars and institutional reports (Schaffer & Douglas 2004, Nugent 2005, and PBS 2003) have identified challenges with learning objects lacking reliable pedagogical and curricular context due to the need for interpretation of raw materials by teachers and students (Nugent 2005). Technical challenges in learning objects include pedagogy and context relationships, issues with metadata in digital portals, and digital rights to content. This is a study of metadata representations of learning objects. The goal of this study was to propose and apply a comparative taxonomy to classify learning objects based on Bloom's Taxonomy in 2006 and Peschl's modes of knowing in 2007, thus adding to the discourse on taxonomies present in learning object repositories and knowledge-oriented educational processes existing in public broadcasting and educational new media content domains. In an effort to re-examine the data and conclusions, I matched Bloom's model against modes of knowing keywords put forth by Peschl (2006). Matching the Peschl model against the Bloom model provided a new template to use in determining the cognitive level of learning objectives embedded in PBS TeacherSource website learning objects.

- Abstract
- RLG has used METS for a particular application, that is as a wrapper for structural metadata. When RLG cultural materials was launched, there was no single way to deal with "complex digital objects". METS provides a standard means of encoding metadata regarding the digital objects represented in RCM, and METS has now been fully integrated into the workflow for this service.
