- We aim to show how some of the important interdisciplinary fixes or solutions to diverse problems observed in fisheries can complement each other. This can be achieved through methodical allocation of the rights pertaining to fisheries and simultaneous implementation of policy instruments to correct for market failures and equity concerns. We emphasize via a roadmap that there are some general principles that should be invoked when choosing between alternative structures of rights. Our examples from Sweden provide evidence of the flexibility of fishing rights and how they can be adapted to integrate fixes from different disciplines into practical fisheries management.

Anaerobic digestion of alfalfa silage with recirculation of process liquid
- 2007

- Process liquid recirculation initially stimulated one-phase anaerobic digestion of alfalfa silage in two semi-continuously fed and stirred tank reactors. Thus, with increased pH, alkalinity and stability it was possible to increase the organic loading rate to 3 g VS L-1 d-1, as compared to 2.25 g VS L-1 d-1 in a control reactor without recirculation. However, the recirculation of liquid eventually caused an accumulation of organic and inorganic substances, leading to an inhibition of hydrolysis and methanogenesis. This inhibition of microbial activity was prevented in one of the processes by replacing 50% of the recirculated process liquid with water during the second half of the operation period. A multiple linear regression model of principal components using seven input variables explained the variance in output variables nearly as well as the original model using all 23 measured input variables. The results show that it is necessary to adjust the degree of liquid recirculation to reach an optimal process. © 2005 Elsevier Ltd. All rights reserved.

Relations between selected musical parameters and expressed emotions : extending the potential of computer entertainment
- 2005

- A fundamental aspect of music is its ability to express emotions. To develop and extend the potential of music in computer entertainment, a deeper understanding of music's emotional aspects is essential. An experiment was designed to explore the suitability of a specially designed interface (REMUPP) as a means to investigate how musical parameters can contribute to expressing the emotions of 'happiness' and 'sadness'. In the experiment, a number of subjects listened to music examples where the musical performance was governed by a set of musical parameters that were controlled by the subject. The subjects adjusted the parameter settings to best express a given emotion. These settings were recorded and analyzed. The experiment verifies the REMUPP tool as a valid means for the investigation of musical parameters and emotion. Issues of importance for realization of music in the computer entertainment context are also addressed.

Assembly processes and materials supply systems design
- 2009
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Lean production has over the last decades emerged as the most important paradigm for production, with the assembly processes in focus, including the objective to minimize non-value-adding work. Thus, much attention has been on the work of the assembly operator. However, little focus has been devoted to how the new requirements from lean production have been transformed into materials supply systems supporting the assembly processes. Hence, the purpose of this thesis is to contribute to increased knowledge about the relation between assembly processes and materials supply systems design.A framework is introduced in this thesis, describing how requirements from the assembly processes are transformed by the materials supply system into the actual materials flow. In the results of this thesis, a model structuring requirements in materials supply and assembly processes is proposed, tested, and subsequently different requirements were identified. Materials exposure is introduced as the transition from the materials supply system to the assembly system. Results show that that the materials exposure has a large impact on assembly workstations performance in terms of space needed, non-value-adding work and ergonomics. Further, an experiment showed that the materials exposure factors with the largest impact on picking time were packaging, angle of packaging and height above floor.Major contributions in this thesis are the identification and structuring of requirements in assembly processes and materials supply systems, and explaining how the materials exposure affects the assembly processes. How this knowledge can be applied in the design of new, or redesign of existing, production systems and materials supply processes in particular, is a managerial contribution.

Auralization of traffic noise within the LISTEN project : Preliminary results for passenger car pass-by
- 2009
-
Ingår i: Euronoise 2009. - Edinburgh : Institute of Acoustics.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Auralization of future traffic noise scenarios would be a valuable tool for city planners, noise consultants and decision makers, since it would make it possible to evaluate various noise mitigation solutions already at the planning stage. The main goal of the Swedish multidisciplinary research project LISTEN is to develop such a tool. In the present paper, auralizations of a single pass-by of a passenger car are investigated with respect to different simulation approaches, and the methodologies behind the approaches are described. Three listening experiments were conducted in order to perceptually evaluate the auralizations. The results showed a high degree of perceptual agreement between real and auralized sounds. However, slight differences between real and auralized sounds were found for perceived realism, annoyance and speed of vehicles, which calls for further improvements of the auralizations.

The disciplinary effect of the single market on Swedish firms

Tidskriftsartikel (refereegranskat)abstract
- In the 1980s it became increasingly clear that the European Community market was still segmented by national borders because of non-tariff barriers to trade. A major objective of the Single Market Program in 1992 was to remove these barriers, thereby enforcing intra-union competition. In this paper, a panel of Swedish firm-level data is used to evaluate whether domestic market power has been curtailed as a consequence of the SMP and of the Swedish membership in the European Union in 1995. Evidence of increased competition emerges, as price-cost margins have declined in industries with high non-tariff barriers prior to 1992.

Who Leaves after Entering the Primary Sector? Evidence from Swedish micro-level data
- 2008
-
Ingår i: European Review of Agricultural Economics. - : Oxford University Press (OUP). - 0165-1587 .- 1464-3618. ; 35:1, s. 41302-41302

Tidskriftsartikel (refereegranskat)abstract
- Using 14 waves of panel data, this paper investigates why employees entering the primary sector exit subsequently. Transition probabilities are explained by a rich set of individual, regional and sectoral characteristics and a discrete-time competing risks model with unrestricted base-line hazards is used to distinguish between exits into a job in other sectors and other exits. The results confirm Jovanovic's suggestion of 'survival of the fittest matches' as workers and firms learn more about the quality of the match between them. It is found that agricultural education, higher income and sector wage differences are the main determinants of the hazard of moving to another sector, whereas marriage and higher education lower the hazard of leaving for non-employment.

Acoustic Design Artifacts and Methods for Urban Soundscapes
- 2008
-
Ingår i: The 15th International Congress on Sound and Vibration In: International Journal of Acoustics & Vibration. ; , s. 52-52
-
Konferensbidrag (refereegranskat)abstract
- The research question is: “How to develop and apply acoustic artifacts and design methodologies for improving soundscapes in urban outdoor spaces?” In the project, this research question is limited to two specific types of urban outdoor spaces – city-park and city-square – and to two types of acoustic design artifacts. These are: I. Dynamic promotion of qualitative site specific sounds (e.g., the overall site specific sonic atmosphere, sounds from human activities, birds and fountains), which creates an improved soundscape. II. Sound-art installations, that creates delimited auditory sub-spaces within the park/square. The purpose and method is: 1. To provide two case-studies of artistic soundscape improvement, one in a noise polluted city-park and one in a city-square. The case-studies will serve as models for future applications of the new acoustic design artifacts. 2. To create and validate an innovative acoustic design methodology based on state-of-the-art real-time acoustic simulation tools integrated into the design process. The methodology will be validated in psychoacoustic listening experiments and field studies. 3. To determine the potential of the two acoustic design artifacts (I Dynamic promotion of qualitative site specific sounds, and II Sound-art installations) for providing pleasant and restorative soundscapes, in order to strengthening the social interaction as well as the spatial and aesthetical qualities in noise polluted city parks/squares. The present project beats a new track by combining acoustic design with sound art research, integrating methodologies based on real-time acoustic simulation and application of psychoacoustic methodology for validating simulations and for evaluating perceptual, emotional and behavioural effects on visitors to public open spaces. The ongoing research project, financed by the Swedish Research Council, is executed by the University College of Arts, Crafts and Design (Konstfack), Gösta Ekman Laboratory – Stockholm University and Karolinska Institutet and the Interactive Institute, all in Stockholm, Sweden.

New printing technology and pricing
- 2009

Ingår i: Industrial Marketing Management. - : Elsevier BV. - 0019-8501 .- 1873-2062. ; 38:3, s. 253-262

Tidskriftsartikel (refereegranskat)abstract
- This case study analyzes five Swedish printing houses' pricing with respect to their investments in new printing technology. The new printing technology made it possible for the printing houses to market new products and services to meet the demand for shorter delivery times and full service solutions. Although this demand was apparent, the printing houses' opportunities to capitalize on their investments depended on the characteristics of the market segment that they served. Findings indicate that the new printing technology made it possible to change prices when the new services reduced delivery time and costs, and when there were substantial differences between the new services and available substitutes. Thus, customers accepted new pricing when the utilization of the new technology resulted in financial gains and time reductions.
