In this paper the problems of organization and representation of concept knowledge are addressed from an autonomous agent perspective. The first part of the paper discusses the question of why an autonomous agent needs concepts at all and what other uses it can make of them. After the necessary and/or desirable functions of concepts have been identified, previous attempts to represent concepts are

Olsson and his collaborators have proposed an extension of Belief Revision Theory where an epistemic state is modeled as a triple S=⟨K,E,A⟩ , where A is a research agenda, i.e. a set of research questions. Contraction and expansion apply to states, and affect the agenda. We propose an alternative characterization of the problem of agenda updating, where research questions are viewed as blueprints

Popular Abstract in Swedish En av tre svenskar drabbas av cancer. Hälften av de som behandlas för sin cancer får strålbehandling som en del av sin behandling. Teknikutvecklingen gör att strålbehandling kan levereras på mer och mer avancerade sätt. Det är dock svårt att veta vilka patienter som verkligen gynnas av behandling med en avancerad teknik och i så fall med vilken typ av avancerad teknik. Radiotherapy is one of the major tools for treating cancer. Through research and technical development radiotherapy is becoming more advanced with new treatment techniques emerging. In the work presented in this thesis, well-known methods have been used, or modified for use, and new methods have been introduced in order to optimise the clinical use of an advanced radiotherapy treatment technique,

The aim of this article is to increase the understanding of how institutional forces and organizational context, in parallel with cognitive issues, impact knowledge sharing within multinational corporations (MNCs). Furthermore, the aim is to elaborate on differences between industries by comparing and contrasting a retail firm with a manufacturing firm. The focus is on IKEA and SCA Packaging and t

The pathophysiologic mechanisms in type 1 diabetes (T1DM) involve loss of islet β-cell secretory function caused by selective killing of these cells primarily by aggressive autoimmune responses involving both cellular and humoral immune pathways. Inflammatory cells heavily infiltrate pancreatic islets leading to insulitis where CD8+ T lymphocytes are thought to be responsible for selective and spec

In Sweden, accident statistics reveal little, if any, evidence of improvement in health and safety on construction sites. Accident statistics, which adopt a reactive approach, must not be looked upon as merely numbers and figures. They must be able to reveal the underlying factors contributing to the accidents. This paper aims to examine construction safety performance based on accidents data from

The aim of this work is to investigate the internal dynamics of power-exercising in compulsory school and wage labor. The exercise of power is structured by four interrelated power-practices: maintenance, that is the practice which produce and reproduce a power relation through, among other things, the enrolment of subordinates; acculturation, the alteration-of-man power that is exercised inside t
