Agglomeration, clusters and entrepreneurship : Studies in regional economic development
- 2014
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Regional economic development has experienced considerable dynamism over recent years. Perhaps the most notable cases were the rise of China and India to emergent country status by the turn of the millennium. With time now for hindsight, this book identifies some of the key forces behind these development successes, namely agglomeration, clusters and entrepreneurship.

Tidskriftsartikel (refereegranskat)abstract
- Weld filler alloys that exploit transformation plasticity through low austenite to martensite transformation temperatures offer an effective method of reducing residual stresses in strong steel welds. However, in multipass welds, the heat input from later weld passes may be insufficient to retransform prior welding passes, leading to the accumulation of thermally induced strains and elevated residual stresses. In this work, the residual stress distributions produced around arc welds fabricated with a martensitic weld filler alloy that transforms at a low temperature have been studied as a function of the number of passes deposited and the interpass temperature. It is found that when the interpass temperature is above the transformation temperature of the weld metal, the entire multipass weld transforms as a single entity, thus permitting the optimum exploitation of the transformation plasticity. In contrast, the deposition of new metal with a relatively low interpass temperature leads to increased residual stresses in the underlying layers, reducing or eliminating the beneficial stress states previously created.

Entrepreneurship, social capital and governance : Directions for the sustainable development and competitiveness of regions
- 2012. - 1
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- This book highlights the role of entrepreneurship, social capital and governance for regional economic development. In recent decades, many researchers have claimed that entrepreneurship is the most critical factor in sustaining regional economic growth. However, most entrepreneurship research is undertaken without considering the fundamental importance of the regional context. Other research has emphasized the role of social capital but there are substantial problems in empirically relating measures of social capital to regional economic development. © Charlie Karlsson, Börje Johansson and Roger R.
