The ability to distinguish danger from safety is crucial for survival. On the other hand, anxiety disorders can result from failures to dissociate safe cues from those that predict dangerous outcomes. The amygdala plays a major role in learning and signaling danger, and recently, evidence accumulates that it also acquires information to signal safety. Traditionally, safety is explored by paradi...

Linguistic and psycholinguistic evidence is presented to support the use of structure-mapping theory as a framework for understanding effects of iconicity on sign language grammar and processing. The existence of structured mappings between phonological form and semantic mental representations has been shown to explain the nature of metaphor and pronominal anaphora in sign languages. With respe...

This paper proposes an alternative approach to the examination of artifacts whose contents must be traceable to promote software quality. The approach places emphasis on media use and media transformations. We suggest that one cannot begin to assign and sustain traceability relations at a micro-level between units of content if the sign systems that have been created and transformed to represen...

Originally published in 2003, this article presents one of the first attempts to provide a systematic summary of the new concept of cultural technique. It is, in essence, an extended checklist aimed at overcoming the textualist bias of traditional cultural theory by highlighting what is elided by this bias. On the one hand, to speak of cultural techniques redirects our attention to material and...

s the proliferation of applications accelerates, users find themselves losing the authentication war; every application that they are introduced to requires its own authentication or login. Some applications do this because they need to identify the user they are dealing with. Other applications do so because they simply do not trust anyone else to conduct authentication for them. The evolution...

The purpose of this research is development of an algorithm for hardware implementation for number recognition applying in speed traffic-sign recognition system for car driving assistant. We recognize the speed limit of the speed traffic-sign using hardware oriented extraction algorithm. The numbers are recognized by comparing their feature values with the recognized features. The proposed hard...

Prosodic structure in sign languages is encoded by articulations of the hands, face, and body. Despite the different physical system, there are many similarities to prosody of spoken language, such as the existence of a prosodic hierarchy, alignment of intonational elements (conveyed by the face) with temporally marked prosodic constituents (conveyed by the hands), and a close relation between ...

Short abstract Compounding is one of the few sequential word formation processes found across sign languages. We examine the properties of compounds in languages in the visual-gestural modality, showing both similarities to spoken language compounds, as well as a modality-specific type of simultaneous compounding. We also explore the development of compounds in a new sign language, (Al-Sayyid B...

Safety cases offer a means for communicating information about the system safety among the system stakeholders. Recently, the requirement for a safety case has been considered by regulators for safety-critical systems. Adopting safety cases is necessarily dependent on the value added for regulatory authorities. In this work, we outline a structured approach for assessing the level of sufficienc...
