1. New ways of learning : Participatory action research and Kenyan runners’ appropriation of smartphones to improve their daily lives and participation in m-learning
Sammanfattning : In Kenya, mobile technology is widely used, with more and more people gaining access to the Internet. Mobile technology has the potential to support learning and improve lives, particular those of impoverished people. In this study, 30 Kenyan runners from poor backgrounds and with limited formal education participated. LÄS MER
Sammanfattning : Technological knowledge is of many different kinds, from experience-based know-how in the crafts to science-based knowledge in modern engineering. It is inherently oriented towards being useful in technological activities, such as manufacturing and engineering design. LÄS MER
Sammanfattning : This thesis consists of two essays and an introduction. The main theme is technological knowledge that is not based on the natural sciences.The first essay is about rules of thumb, which are simple instructions, used to guide actions toward a specific result, without need of advanced knowledge.

Sammanfattning : In this thesis, the first determination of the electric charge of the top quark is presented using 370pb-1 of data recorded by the DØ detector at the Fermilab Tevatron accelerator. ttbar events are selected with one isolated electron or muon and at least four jets out of which two are b-tagged by reconstruction of a secondary decay vertex (SVT).
