  2. 1. Agency and Artefacts : A cognitive semiotic exploration of design

    Author : Juan Mendoza-Collazos; Kognitiv semiotik; []
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agency; enhanced agency; agency hierarchy; derived agency; material agency; intentionality; prior intentions; intentions in action; pictorial representations; artefacts; tool-making; design theory; design semiotics; design research; phenomenology; cognitive semiotics; agentive semiotics; semiotic hierarchy; 4E cognition; bio-cultural evolution; philosophy of design; philosophy of technology;

    Abstract : This thesis investigates the role of artefacts in relation to human agency and design within a cognitive semiotics framework. It deals with questions such as What is agency? What are artefacts and how does agency relate to them? What kind of intentions are involved in the activity of designing? What is human-specific with respect to agency and design? How can the origins and evolution of design be explained? Addressing these questions, the thesis proposes a layered model of agency for explaining the relations between different grades of agentive complexity. READ MORE

  4. 2. Picture Viewing and Picture Description: Two Windows on the Mind

    Author : Jana Holsanova; Kognitionsvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; discourse hierarchy; picture description; vision; picture viewing; information flow; discourse segmentation; discourse analysis; coherence; semantics; spatial and temporal relations; cognitive science; linguistics; cognitive linguistics; psycholinguistics; speech; cognition; multimodal communication; mental processes; eye movement protocol; focus of attention; spoken language protocol; information processing; scene perception; areas of interest;

    Abstract : In this thesis, I connect two disciplines, linguistics and vision research, and combine two methods, spoken language protocols and eye movement protocols, in order to cast light on the underlying cognitive processes. In a series of studies, I investigate the processual aspects of picture viewing and picture description. READ MORE

  5. 3. On Dynamic Spectrum Access in Cognitive Radio Networking

    Author : Said Rutabayiro Ngoga; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio; Cognitive Radio Networking; Dynamic Spectrum Access; Wireless Communications;

    Abstract : The exploding increase of wireless communications combined with the existing inefficient usage of the licensed spectrum gives a strong impetus to the development and standardization of cognitive radio networking and communications. In this dissertation, a framework for Dynamic Spectrum Access (DSA) is first presented, which is the enabling technology for increasing the spectral efficiency of wireless communications. READ MORE

  6. 4. Aiming at Moving Targets : Applying Cognitive Work Analysis to Work Domains in Transition

    Author : Ida Löscher; Anders Arweström Jansson; Åsa Cajander; Camilla Fröjd; Stas Krupenia; Catherine Burns; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cognitive work analysis; work domain analysis; control task analysis; strategies analysis; abstraction hierarchy; contextual activity template; activity prioritization; systems design; heavy vehicle development; long haul trucks; intensive care; nursing; digitalization.; Computer Science with specialization in Human-Computer Interaction; Datavetenskap med inriktning mot människa-datorinteraktion;

    Abstract : The design of IT systems for complex work environments is essential for workers to be able to operate more effectively and efficiently. To design a system that supports the workers' specific tasks we need to understand the work demands and the context in which the system operates. READ MORE

  7. 5. Comparative studies of cognitive abilities in the Paridae : Evidence from laboratory studies

    Author : Utku Urhan; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Comparative cognition; Spatial memory; Food hoarding; Observational spatial memory; motor self-regulation; Cognitive sex differences; foraging strategies;

    Abstract : The Paridae (tits, titmice and chickadees) is a bird family consisting of both food hoarding and non-hoarding species. Many studies have been conducted on birds that are considered to be cognitively advanced, such as parrots and corvids, whereas much less is known about these small passerines. READ MORE
