In this paper we present an interactivist perspective on design principles for autonomous sign users such as autonomous robots. Past discussions have centered around symbol grounding or anchoring where concepts are considered prototypes in the perceptual space of a robot or animal. Here we advocate a more complex view starting from the purpose of using signs or pursuing sign acts. We argue that...

BACKGROUND The problem of safe and efficient transfer of care has increased over the years as new and complex diagnostic tools and more complex treatment options became available. Traditionally, residents ensured continuity of care by working long hours and minimizing the transfer of significant diagnostic or therapeutic responsibilities to other providers. The new 80-hour workweek has curtaile...

In the UK, the Highways Agency has been investigating the use of Graphical Congestion Display Panels (GCDPs) to display real-time congestion and journey time information relevant to drivers on sections of the trunk road network. A GCDP can potentially display a greater detail of traffic information than traditional Variable Message Signs (VMS). The research described in this paper has investiga...

Illegal use of reserved parking spaces represents a major obstacle to the independence and mobility of people with physical disabilities. Using an ABACACA reversal design, the daily rates of illegal parking in four reserved spaces were examined across three types of sign displays: (a) a vertical sign alone or in combination with (b) a message sign that announced the possibility of public survei...

TSR (Traffic sign recognition) is an important problem in ITS (intelligent traffic system), which is being paid more and more attention for realizing drivers assisting system and unmanned vehicle etc. TSR consists of two steps: detection and recognition, and this paper describe a new traffic sign detection method. The design principle of the traffic sign is comply with the visual attention mech...

Title of dissertation: FORM, MEANING AND CONTEXT IN LEXICAL ACCESS: MEG AND BEHAVIORAL EVIDENCE Diogo Almeida, Doctor of Philosophy, 2009 Dissertation directed by: Professor David Poeppel Department of Linguistics One of the main challenges in the study of cognition is how to connect brain activity to cognitive processes. In the domain of language, this requires coordination between two differe...

The use of semiotics has been proposed in studying the ways in which information is mediated in computer systems, particularly in user interfaces. Goguen's algebraic semiotics provides a formal tool for studying the systematic use of signs in computer systems, and for presenting formal comparisons of diierent interface designs. The formal elements of algebraic semiotics make it a kind of algebr...

An important argument in favor of the encyclical theory of the epistle to the Ephesians is based upon the peculiarities found in the epistle itself. Yet these unusual features (e.g., the lack of personal greetings, the unusual statements in 1:15, 3:2, and 4:21, etc.) can all be satisfactorily explained in the light of an original Ephesian destination. After an examination of early scribal habit...
