Barriers to growth in small firms
- 1999
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- It has been indicated in literature that growth of small firms is essential for job creation, for the national economy and for development as a whole. In order for small firms to realise their growth potential, it is essential that the small firms manage to overcome various barriers to growth along the way. These barriers that hinder the growth of small firms are discussed and analysed in this extended summary. The extended summary pinpoints the general barriers to growth identified in literature and develops further knowledge of dominant barriers to growth in small firms. It is argued in the extended summary that lack of appropriate change of the organisation structure as the firm's size increases, is to be regarded as a dominant barrier to growth. When the small firm has a simple structure it is usually the small business manager that controls most of the activities within the firm, but when the organisation size increases it is important that also control and responsibility are differentiated among various functions. This internal change in the firm demands different and formal ways of co-ordinating the venture. This study indicates that the small business manager does not delegate responsibilities and decision-making to various functions until the number of employees has reached a certain level. This threshold value indicates a distinctive barrier in the simultaneous growth in size and differentiation of a small firm. A small firm encounters a barrier when the organisation size no longer matches its current structure. A small firm may have a very simple and informal structure, but when the number of employees grows, so will the need to differentiate and specialise the way in which work is done. It has also been argued in this extended summary that there is a relationship between firm performance and organisation structure. From this point of view, the small business manager will not only face problems with co-ordination and control as the firm size increases: his/her firm will also perform worse than firms that recognise the importance of structural implications when the number of employees increases.

Managerial barriers to growth in Sweden
- 1999
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This paper focuses on the situation when a firm moves from being an entrepreneurially managed firm to a professionally managed firm. A small firm may have a very simple structure, but when the number of employees grow, so will the need to differentiate and specialise the way work is done. During that transformation, when the organisation and the management principals are changed, leading to a temporary slack of control of the firm, a decrease of economic performance is hypothesised.

Strategy, Structure and Technology as Influential Factors on Performance in SME´s
- 1999
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Significant literature has focused the relationship between performance and the use of technology, strategy and structure in small and medium sized enterprises (SME); either separately or considering the interaction of some of these three issues at the same time.This paper, however, tries to develop a better knowledge of how structure, strategy, technology relates to the firm size as an aspect of firm performance. The survey study consists of 330 service and manufacturing small firms in Sweden with up to 200 employees.

Sharp weighted multidimensional integral inequalities of Chebyshev type
- 1999
-
Ingår i: Journal of Mathematical Analysis and Applications. - : Elsevier BV. - 0022-247X .- 1096-0813. ; 236:2, s. 243-253

Tidskriftsartikel (refereegranskat)abstract
- We prove a general Chebyshev inequality for monotone functions in higher dimensions. This result generalizes the classical one-dimensional inequality and recovers some extensions already known for product weights. In all cases we find the best constant in the inequality. We also consider the case of more general operators.

Weighted multidimensional integral inequalities and applications
- 1999
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In this thesis some new weighted integral inequalities for monotone functions in higher dimensions are proved. These results extend previous results in one dimension, and also those in higher dimensions for particular choices of the weights (power weights, etc.). All inequalities are sharp. A new duality principle (of Sawyer type) over the cone of multidimensional monotone functions is proved and applied. Weighted Chebyshev type inequalities for monotone functions and modular inequalities in higher dimensions are proved. A new type of weighted function spaces are introduced. In particular these spaces generalize the classical Lebesgue spaces. The weights such that they become quasi-Banach spaces are completely characterized. A multidimensional multiplicative inequality (of Carlson type) for weighted Lebesgue spaces with homogeneous weights is proved and applied. The inequality is sharp and all cases of equality are pointed out.

External model repetitive controller for active vibration isolation
- 1999

Ingår i: Proceedings of Active 99. - Washington, DC : Institute of noise control engineering. - 0962207225 ; , s. 177-188

Konferensbidrag (refereegranskat)abstract
- This paper deals with the External Model Repetitive Controller, a structure that combines the classical repetitive disturbance model (in the form of a time delay with a unit feedback) with a feedback of a disturbance estimate. The latter is often termed the External Model Controller and has a broad spectrum of technical applications, e.g., active vibration control. By analyzing the controller performance under the assumption of a disturbance period modeling error, it is shown that an unacceptable performance degradation might occur even for very small values of the modeling error
