Transmission understood as the process in which ＂agencies and human actors transmit the ideas in historical and diachronic order＂ and communication implying the ＂synchronic interchange by linguistic impact between senders and receivers＂ are presented as two paths in which cultural messages are introduced and transmitted by means of ＂literary production＂. Early Greek literature, which was based on the oral performance and mirrored the language in its prototypical form, seemed to be the main source of information for the reconstruction of the two above processes. In the proposed model, the new understanding of the media introduced by Debray plays the most important role, because in the theory of ＂cultural transmission＂, the medium can be not only ＂a symbolic process, a social code, a material device＂ but also a human being. Therefore, on the basis of this theory, mediology can be described as the way of 4M： message, medium, milieu, and mediation.展开更多

A method based on constraint programming is proposed for identifying inconsistency or proving consistency in information models. The system described here checks information models written in the ISO standard information modelling language EXPRESS. EXPRESS is part of the ISO STEP standard used in the manufacturing and process industries. This paper describes the checking procedure, including EXPRESS model formalization, constraint satisfaction problem (CSP) derivation from the formalized model and satisfaction checking of the derived CSPs. This paper shows a new domain in which constraint programming can be exploited as model verification and validation.展开更多

There is a special digital divide between semiotics and the technology, because the semiotic notions are usually expressed through verbal expressions instead engineers use the mathematical language. In the first step, the present study suggests the formal descriptions of the signifier and the signified. In the second step, we show how these formal definitions are able to justify the hardware structure of a computer system, and even other properties of computing which are currently presented on the as-is basis. Concluding, the basic concepts of semiotics can unveil intriguing aspect of information technology展开更多

In comparison with sequentially coded spoken language and written texts, we are capable of consuming graphical information at a high bandwidth in a parallel fashion, producing a picture worth more than a thousand words. Effective information visualization can be a powerful tool to capture people's attention and quickly communicate large amounts of data and complex information. This is particularly important in the context of communication data, which often describes entities (people, organizations) and their connections through communication. Visual analytics approaches can optimize the user-computer interaction to gain insights into communication networks and learn about their structures. Network visualization is a perfect instrument to better communicate the results of analysis. The precondition for effective information visualization and successful visual reasoning is the capability to draw "good" pictures. Even though communication networks are often large, including thousands or even millions of people, underlying visualization principles are identical to those used for visualizing smaller networks. In this article, you will learn about these principles, giving you the ability to assess the quality of network visualizations and to draw better network pictures by yourself.展开更多
