Under lång tid har såväl studenter som lärare inom humaniora önskat och krävt mer lärarledd undervisningstid. I väntan på det vill jag emellertid diskutera hur man som lärare kan hjälpa studenterna att utnyttja självstudietiden på ett så effektivt sätt som möjligt med ett minimum av lärarresurser, för att på så sätt öka kontakttiden med ämnet. Diskussionen tar sin utgångspunkt i pedagogisk forskni

To achieve their business objectives, software developing companies employ different technical and managerial strategies concerning architecture and reuse. These strategies include component-based development, software platforms, product lines and highly configurable code bases. Frameworks for describing these strategies have recently emerged, presenting them in orders of increasing maturity, with

This thesis is comprised of five papers that are all related to the subject of financial time series. We study statistical aspects of conditional heteroskedastic models commonly used in modelling financial volatility. Paper I discusses the performance of commonly known information criteria in the presence of various GARCH processes. The investigation has been performed using Monte Carlo simulatio

In 1999 a new and simplified procedure for calibration of the Owren prothrombin time (Owren PT) assay was introduced in Sweden by the national external quality assessment scheme (Equalis). The new protocol allowed local calibration by means of lyophilised national plasma calibrators and expression of results as an international normalised ratio (INR). A two-year follow-up involving analysis of dat

This paper presents the first quadrature RF receiver front-end where, in a single stage, low-noise amplifier (LNA), mixer and voltage-controlled oscillator (VCO) share the same bias current. The new structure exploits the intrinsic mixing functionality of a classical LC tank oscillator providing a compact and low-power solution compatible with low-voltage technologies. A 0.13-mum CMOS prototype ta

The early medieval cult of saints has been the object of many illuminating studies during the past decades. However, one aspect in need of more research is the role of the cults in the building of early states in Europe, a phenomenon that is often, somewhat erroneously, referred to as the cult of national saints. The saints were powerful assets in the attempts of kings, dukes and bishops at achiev

Pain is common in the elderly population and its prevalence varies according to the studied disease, clinical setting, sex and age. This study examines pain in an aging population from a gender perspective.
