IT has direct and observable positive effects for consumers. For firms, the situation is somewhat different, because efficiencies generated by publicly available technology tend to be competed away. Therefore, researchers from the strategy field and students of information systems have concluded that for firms, the opportunity lies in using IT better than competitors rather than in the technology
This thesis, which consists of three studies illustrating different angles of approach, discusses problems pertaining to accounting and allocation costs in municipal water and sewage enterprises. Water and sewage enterprises are financed by charges to users, and are generally run under the auspices of a municipal administration or within the framework of a municipal company. User fees are regulat
Membrane proteins are fairly refractory to digestion especially by trypsin. Less specific proteases like elastase and pepsin are much more effective. However database searching using non-tryptic peptides is much less effective due to the lack of charge localisation at the N- and C-termini and the absence of sequence specificity. We describe a method for N-terminal specific labelling of peptides fr
New information technology is developing faster than the models, metaphors and methods in use for conceptualizing the sharing and managing of information in organizations, in communities and in society in general. The way we utilize information technology today does not seem to succeed in supporting the everyday work practices through which organizations accomplish their work. In this Ph.D. disser
The aim of this thesis is to study collective excitation dynamics in molecular aggregates. Half of the work presented here is method development and the remainder is application of these methods to several di.erent molecular aggregates. In the first two papers, the pump-probe signal was derived using the Green function approach of the optical response functions and formulated in the Doorway-Window
The thesis aims to describe, analyse and interpret the conditions of the upbringing process and the socialization process in a group of eleven-year-olds while the process is still ongoing, and to do this with the help of the eleven-year-olds? narrations about their families and about how the children themselves view their families and their upbringing. The research approach is inspired by phenomen
The molecular specification of neural precursor cells has been suggested to be a progressive process, with a transition from an early requirement for extrinsic signals to intrinsic mechanisms. Thus, the cells in the nervous system acquire distinct fates in response to extrinsic signals, which activate repertoires of transcription factors in a region and cell type specific manner. The studies in th
This thesis argues that the Western thinking of political community has assumed the community to require a unity or unifying principle that serves as delineation. It suggests that sameness, reflected in history, space, language, or reason, has been assumed as the condition of possibility of the political community. Consequently, a particular identity is made a prerequisite for membership and vouch
This thesis proposes the use of two concepts: accessibility and chemical activity. Accessibility describes the mass quantity of PAHs that is or can become available within a given time span and under given conditions. Chemical activity quantifies the energetic state of the PAHs that determines the potential for spontaneous physicochemical processes, such as diffusion and partitioning. Chemical act
Peptostreptococcus magnus and group C/G streptococci are Gram-positive cocci that are part of the normal flora and reside in more or less the same locations in the host. Protein G of group C/G streptococci was originally described as binding IgGFc of several species and later shown to also bind human serum albumin and albumins from various animal species. From albumin-binding strains of P. magnus
The sound absorption characteristics of resonant absorbers, implemented as perforated suspended inner ceilings attached with thin porous layers, are investigated. Several existing theories model the principal absorption mechanisms, but the interaction with the outer sound field influences the absorption in ways that can be modelled with new approaches. The effect of arranging the absorbing surfac
Cavitation is a problem in many hydroelectric power plants since it can cause adverse effects on performance and damage to nearby solid surfaces. The concerns of this thesis are the numerical aspects of flow simulations in cavitating hydraulic turbines which contain several difficulties: turbulent and complex flows, steady and moving parts of the geometry, bubble transport and cavitation developme
In navigable waterways, owing to the relatively short fetches for wind wave generation, the free waves generated by moving vessels often produce the dominant wave action with respect to erosion of the shore. In response to the fairly recent introduction of high-speed ferries, combined with a planned expansion within the passenger- and car-carrying ship market, the need to model and predict coastli
The industrial production of preserves includes several unit operations which all affects sensorial properties as well as the nutritional value of the final product. Thawing is a crucial unit operation, since then both chemical and physical changes take place. Thawing strawberries in selected aqueous media could gave both firmer strawberries and smaller weight loss than if air was used as the tha
This thesis investigates the relationship between the “New Negro” moment of the early twentieth-century America and the Old World of Europe, as represented in James Weldon Johnson’s The Autobiography of an Ex-Colored Man (1912), Jessie Fauset’s There is Confusion (1924), and Nella Larsen’s Quicksand (1928). In the nineteenth century, Europe functioned as a symbol of freedom, education and art in t
In this thesis the notion of place is studied by way of investigating the “non-place” which is excluded or opposed, whenever a place is defined. “Non-place” is used here as a meta-concept, covering various recurring types of opposition to “place,” and it therefore represents a profoundly incoherent spect-rum of realities and concepts. Hence, a “non-place” may in this investigation appear as “lefto
Each immunoglobulin (Ig) V gene segment contains an upstream promoter region. The octamer element and the TATA box are the only elements that are conserved in all Ig promoters. The presence of the octamer element is necessary, but not sufficient to support high levels of transcription. Therefore, the activity of other co-stimulatory elements is required. This investigation has focused on the study
