Network economy in service- and context-aware next generation mobile networks

The Internet, mobile telephony and portable computers let today's user meet novel applications provided by the service developers, who are motivated by the popular customer trends in technology. However, the supply-demand chain observed in telecommunications causes the complexity of both the user devices as well as the network to increase. The complexity is caused by the need to support quality of

Den rotfaste bonden - myt eller verklighet? Brukaransvar i Ramkvilla socken 1620-1820

For how many years was a farmer responsible for running a farm in Sweden’s old peasant society’? This is the question that underpins my research into life in Ramkvilla parish in the province of Småland for two hundred years (1623–1819). By conducting a detailed study of farm practice at the individual level, I have been able to analyse a complex theme that touches upon the issues of responsibility

Tools and technology : Lithic technological analysis of Neolithic axe morphology

Through practical experiments, edge-wear analysis, and the study of archaeological collections, the dissertation explores the complex relationship between style and function in a specific class of artifacts: the Neolithic axe. The results of the three-part approach described above, when applied for instance to thin-butted axes from the Funnel Beaker Culture, indicated that there was no clear-cut c

Information Technology Projects: leaving the "magic" to the "wizards".

In this paper, we explore the significant challenges relating to investment in IT in business. Information technology does not in itself deliver business value. We highlight the complexities that are often ignored in management of IT projects. If the management system in an organization is ineffective, then installing information technologies does not constitute a ‘magic wand’ that will generate p

Predicting Stock Price Volatility by Analyzing Semantic Content in Media.

Current models for predicting volatility do not incorporate information flow and are solely based on historical volatilities. We suggest a method to quantify the semantic content of words in news articles about a company and use this as a predictor of its stock volatility. The results show that future stock volatility is better predicted by our method than the conventional models. We also analyze

Evolutionary Genomics of Nematode-Trapping Fungi

Nematode-trapping fungi are ubiquitous, soil-living organisms with the ability to infect and kill nematodes. These fungi have developed specialized infection structures for the capture of nematodes. Many nematode species are parasites on plants and animals, which have resulted in an interest to use nematode-trapping fungi as biological control agents. Through bioinformatics approaches, I have used
