MOVING ROCK: Youth and pop in late modernity

-
In: Popular Music. - 0261-1430 .- 1474-0095. ; 9:3, s. 291-306
-
Journal article (peer-reviewed)abstract
- Popular music in late modernity contains crucial ambivalences that ask for a non-reductionist cultural critique. To that end, a multi-dimensional model is suggested for understanding sources, learning processes, recent changes, and resistance forms in pop and youth culture. On an objective level, a growing systemic rationality of technology, politics and economy induces counter-powers and counter-institutions. On a social level, a gradual release from traditional norms and relations inspire experiments with counter-values and counter-groups. On a subjective level new narcissist personal traits develop, leading to counter-identities. On a cultural level a growing reflexivity make counter-cultures try out open and flexible forms of symbolic interaction and music making.

Internationalization of division management in Swedish international firms
- 1990
-
Reports (other academic/artistic)abstract
- An important issue in the divisionalized firm are the relationsships between the three levels; topmanagement, divisional management and the operational level. In the international firm thephysical location of the divisional management level becomes especially problematic because ofthis level’s strategic role concerning the links to the top management and the foreign subsidiariesrespectively.Most literature on international business leaves no doubt that the parent company, the “centre”,designs the organization and controls the subsidiaries, the “periphery”. However, the relevance ofthis perspective is dependent on the stage of the internationalization process. In later phases ofthis process the subsidiaries can extend their operations to markets outside their own and becomestrong enough to play a strategic role in the group’s total operations within a certain product areaor function. Thus a situation can arise with a firm consisting of several centres located in differentgeographic areas, rather than one centre and a periphery. In the paper this is labeled multi-centrestructure.In a political perspective such centres are expected to have considering influence on the formalorganization structure including the location of the divisional management.In the paper the relation between the internationalization of divisional management and the existence of multi-centre structures in 22 Swedish firms is analysed.

Conference paper (peer-reviewed)abstract
- It is shown how Grobner bases can be used to solve some common problems in nonlinear systems theory efficiently. These problems include finding critical levels of local Lyapunov functions and solving the equations that arise in the harmonic balancing method. The methods proposed are illustrated by some concrete examples in which the computer algebra system Maple is used for performing the necessary calculations.

Book chapter (other academic/artistic)abstract
- This paper discusses how the concepts of differential algebra can be used in the modelling of physical systems. In particular it is shown that the concepts of ranking and characteristic set can be used to give a structure to the set of physical equations. The characteristic set makes it easy to find the number of inputs and the order of the system. The question of observability can also be investigated using the characteristic set. In particular one can see that the order of an input output differential equation will be the same as the system order if and only if all variables are observable from the output.
