Tidskriftsartikel (refereegranskat)abstract
- A method for the 11C-labelling of polysaccharides in high specific radioactivity is described. Dextran and hyaluronan were treated with [11C]cyanogen bromide in aqueous solution at pH 11.5 to give 30-47% radiochemical yields with higher than 98% radiochemical purity in synthesis times of 24-26 min counted from the end of bombardment. Specific radioactivities at the end of synthesis ranged from 0.12 to 3.1 Ci/mumol. The biodistribution kinetics of [11C]hyaluronan injected intravenously was studied in rats by means of positron emission tomography, showing a rapid and displaceable uptake in liver. Uptake and displacement of [11C]hyaluronan was also demonstrated in cultured rat liver endothelial cells.

Does the CEO matter? An empirical study of small Swedish firms operating in turbulent environments
- 1997
-
Ingår i: Scandinavian Journal of Management. - 0956-5221 .- 1873-3387. ; 13:3, s. 251-270

Tidskriftsartikel (refereegranskat)abstract
- This paper develops and tests a framework for understanding the performance of small firms operating in highly turbulent environments. Performance is conceptualized as being multidimensional, taking into account both financial and market performance. The purpose was to delineate the importance of CEO characteristics (self-efficacy, tolerance for ambiguity and need for cognition) in relation to some aspects of firm orientation (Market vs. Internal and Planning vs. Implementation). The results showed that CEO characteristics tended to have a considerable impact on firm performance and on firm orientation, while no significant relationship between firm orientation and firm performance was found.

Managing in turbulence : an empirical study of small firms operating in a turbulent environment
- 1998
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis deals with how small firms, and especially their CEOs, manage their situation in times of high environmental turbulence. Eight firms have been chosen for the empirical study based on their performance and the CEO’s self-efficacy and tolerance for ambiguity. Interviews with the CEO and employees at each firm, observations, gathering of annual reports and a questionnaire are the principal means used for data collection. The results show that the CEO is very influential at all firms, regardless how the company performs. A CEO that tolerate uncertainty is better able to engage in enterprising, which seems necessary in turbulence. A CEO with high self- efficacy is generally able to control his firms destiny by having access to the appropriate resources for the task (e.g. own ability and network). However, too high self-efficacy could be a sign of dysfunctional overconfidence, where the CEO dismiss relevant information from actors around him.
