- Thin films of pure and oxygen doped Cu3N, deposited by Chemical Vapour Deposition, have been studied with the NEXAFS technique both in the FLY and TEY mode and compared with XPS results. Cu, CuO and Cu2O have been used as reference samples in the investigation for detection of surface oxidation and contaminants. The aim has been to investigate how and if the chemical environment changes around Cu, N and O upon incorporation of oxygen in the Cu3N lattice. The recorded NEXAFS spectra are discussed in terms of valence electrons, crystal structure and local bonding environment. It was found that basically two oxygen absorption sites are possible in the crystal structure, (½, ½, 0) and (¼, ¼, ¼), and that the oxygen distribution between the two sites is probably given by the oxygen concentration.

- Recombinant human growth hormone (GH) administered as daily subcutaneous (SC) injections has been shown to affect serum lipoproteins in GH-deficient subjects. However, the effects of continuous infusion of GH on serum lipoproteins have not been investigated in GH-deficient adults. The aim of the present study was to compare effects of daily injections and continuous infusion of GH on lipoprotein metabolism. Recombinant human GH (0.25 U/kg/wk) was administered to nine GH-deficient adult men during a period of 14 days in two different ways, ie, as a daily SC injection at 8:00 PM and as a continuous SC infusion, with 1 month of washout between the treatments. Blood samples and tests were performed in the morning after an overnight fast before the start of GH treatment (day 0) and on day 2 and day 14 of treatment. Abdominal SC adipose tissue lipoprotein lipase (LPL), postheparin plasma LPL, and hepatic lipase (HL) activity were measured 120 minutes after the intake of 100 g glucose. Adipose tissue LPL activity decreased and postheparin plasma HL activity increased after 14 days of GH treatment irrespective of the mode of GH administration, whereas GH treatment had no effect on postheparin plasma LPL activity. Serum triglyceride and very-low-density lipoprotein (VLDL) triglyceride concentrations increased during GH treatment. However, VLDL triglyceride concentrations increased to a greater degree during treatment with daily GH injections than during continuous infusion of GH. Serum apolipoprotein (apo) B and low-density lipoprotein (LDL) cholesterol concentrations decreased during treatment with daily GH injections, but were not significantly affected by continuous GH infusion. Thus, apo B and LDL cholesterol concentrations were lower after daily GH injections versus continuous GH infusion. Serum lipoprotein(a) [Lp(a)] and apo E concentrations increased during both modes of GH treatment. However, continuous infusion of GH resulted in a more marked increase in Lp(a) and apo E concentrations than daily GH injections. Minor effects were observed on serum apo A-I concentrations but high-density lipoprotein (HDL) cholesterol concentrations were not affected. In conclusion, GH treatment of GH-deficient men influenced adipose tissue LPL and postheparin plasma HL activity, as well as serum lipoprotein concentrations. Moreover, continuous GH infusion and daily GH injections differed with respect to the magnitude of effects on several lipoprotein fractions including VLDL triglycerides, LDL cholesterol, apo B, apo E, and Lp(a) concentrations.

Tidskriftsartikel (refereegranskat)abstract
- Although the second half of the twentieth century saw the rise and fall of ‘multi-flag companies’ (MFCs) in the civil aviation industry, our understanding of how some managed to buck the trend and achieve longevity remains limited. This article advances business history and strategic management research by examining the strategic renewal activities of Scandinavian Airlines (formerly Scandinavian Airlines System [SAS]) during the period 1946–2012. The study sheds light on the key roles of private and state owners, rivals as well as banks, in critical financial phases are discussed in terms of longevity in the company. The longevity of the business stems from the leaders’ ability to develop as anticipated and respond to change in their competitive arena in close interaction with the owners. Thus, incumbent firms that strategically renew themselves prior to or during market reform, such as deregulation, enhance their chances of developing the size of their networks and revenue streams. Our main contribution to business history and strategic management literatures is the development of context-specific stages, which shed light on the evolution of strategic renewal activities and shifts from older processes and routines towards customer service and efficiency.

Mot framtiden på gamla spår? : Regionala intressegrupper och beslutsprocesser kring kustjärnvägarna i Norrland under 1900-talet

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In this dissertation the construction of two coastal railways, the East Coast Line and the Bothnia Line, in the Norrland region of northern Sweden is used as a case study of how regionally based interest groups are formed, and how they gain access to decision-making processes on a national level. In periods when a number of preconditions were in place, a window of opportunity opened for the coastal railway that the regional elites could exploit. Among these was the ability to form a coherent regional interest group, through institutions that created platforms and power-bases that enable regional elites to co-operate and act on regional and national levels.The existence of an institutional framework that was adapitve towards regional railway promotion was also important. The study shows that the coastal railway had a very flexible role on the agenda, as it provided a fixed solution against which actors could pin a multitude of different problems. An important factor for explaining the development of the coastal railway question in Norrland was the ideological notion of the region itself. Being a vast, resource-rich and sparsely populated region, Norrland had almost always received special consideration in both public opinion and national policy making. It also created a remarkable stubbornness among the regional actors in working for the coastal railway. Regional interest groups had also learnt that linking their claims to Norrland's peripheral position had high legitimacy on the national arena, by claiming the need for regional fairness and/or the national importance of the regional export-intensive industries. This was instrumental in justifying the repeated exemptions from the national railway policy regimes that ultimately were decissive in making the regional elites successful.
