The thesis is focused on the description of the method for the selection of the information system for the company KOPS spol. Ltd. The work is based on theoretical knowledge for a proper understanding of the issue. In the next part, an analysis of the current state of the company is performed, while monitoring the factors influencing the company and especially the information system. The last part describes the procedure for selecting a system and the possibilities of its implementation to the company.

The scientific and socio-political dimensions of volcanic hazards have been realigned since the eruption of Eyjafjallajökull in 2010, and have highlighted the need for volcanic activity to be studied from interdisciplinary perspectives. By focussing on communication, adaptability and resilience, this research explains the links between hazard management and social constructivism. The research question asks how Iceland’s networked approach to managing volcanoes can be understood by analysing the development of communication channels between human stakeholders and non-human technical devices and systems. Fieldwork was conducted in both Iceland and the UK, and a mixed methods approach was used to engage with the network. Research methods consisted of semi-structured interviews, participant observations and archival research. Findings explain the evolution of knowledge exchange, the value of technical innovation, and the need for interactions between local, national and international stakeholders. The study concludes that actors are increasingly empowered by the use of participatory technologies within hazard management, and the development of collaborative engagements between stakeholder communities from scientific and socio-political backgrounds. This research is relevant as it illustrates how the adaptive capacity of hazard networks can be expanded, potentially influencing the approaches that are taken to manage volcanic hazards in less economically developed contexts. In addition, this study can encourage continued interaction between scientists, at-risk communities and the aviation industry in multi-hazard environments such as Iceland.

There has been an increasing demand for commercial organisations to foster real-time interaction with customers, because harnessing customer competencies has been shown to be a major contributor towards various benefits, such as growth, innovation and competition. This may drive organisations to embrace the development of multimodal interaction and complement Electronic Customer Knowledge Management Systems (E-CKMS) with metaphors of audio-visual nature. Although the implementation of E-CKMS encounters several challenges, such as lack of trust and information overload, few empirical studies were devoted to assess the role of audio-visual metaphors, and investigate whether these technologies can be put into practice. Therefore, this thesis describes a comparative evaluation study carried out to examine the implication of incorporating multimodal metaphors into E-CKMS interfaces on not only usability of E-CKMS, but also the user's trust, knowledge and acceptance. An experimental E-CKMS platform was implemented with three different modes of interaction: Visual-only E-CKMS (VCKMS) with text and graphics, Multimodal E-CKMS (MCKMS) with speech, earcons and auditory icons and Avatar-enhanced multimodal E-CKMS (ACKMS). The three platforms were evaluated by three independent groups of twenty participants each (total=60) who carried out eight common tasks of increasing complexity and design based on three different styles. Another dependent group of forty-eight participants (n=48) was instructed to interact with the systems under similar usability conditions by performing six common tasks of two styles, and fill a questionnaire devised to measure the aspects of user acceptance. The results therein revealed that ACKMS was more usable and acceptable than both MCKMS and VCKMS, whereas MCKMS was more usable than VCKMS, but less acceptable. Inferential Statistics indicated that these results were statistically significant.
