The educational knowledge domain may be understood as a system composed of multiple, co-evolving networks that reflect the form and content of a cultural field. This paper describes the educational knowledge domain as having a community structure (form) based in relations of production (authoring) and consumption (referencing), and a cognitive structure (content) based in relations of ideas and...

There is fine china, fine linens, fine crystal, fine wine, a fine line, and, of course, fine print. In the case of china, linens, crystal, and wine, the modifier, fine, connotes high quality. In the case of a fine line, the reference pertains to the closeness of the distinction being made. However, in the case of fine print, the reference pertains to the specific details related to the more gen...

The implications arising from the distribution of offset ink components in a paper coating structure are presented. The work focuses on two mechanisms causing differential distribution of ink constituents, namely (a) adsorption chromatography, resulting from coating pigment chemistry and morphology variables, and (b) latex-oil diffusional interaction. Adsorption chromatographic fractionation an...

Due to the emergence of e-commerce and developments in print engines designed for economical output of very short runs, there are increased business opportunities and consumer options for print-on-demand books. The current state of this printing mode allows for direct uploading of book files via the web, printing on non-offset printers, and distributing by standard parcel or mail delivery servi...

The focus of the activity of the Inspection Laboratory in the past several years has been high-speed inspection of patterned, surfaces. The Bureau of Engraving prints money on a high-speed "web," which means that large sheets of money are being produced very fast. The question is raised of how to inspect for the print quality at those speeds. People will see either a blur or only a sample of th...

In this paper, the possibility to apply conventional watermarking methods in a print-cam process is discussed. In the print-cam process, the watermark is read from a printed image with a camera phone. The process inflicts serious attacks to the watermark and, especially geometrical distortions. If the distortions are not inverted, they may destroy the watermark. In this paper, the distortions a...

The use of technology to support the digital production, distribution and storage of scientific content in full-text formats poses challenges for authors and publishers as well as for the librarians and scientists who access the materials. While scientific publishers still have to produce high-quality print products, they have had to develop new production systems that are now able to produce b...
