  • Local stakeholders acceptance of model-generated data used as a communication tool in water management: : The Ronnea study
  • 2005
  • Ingår i: Ambio. - 0044-7447. ; 34:7, s. 507-512
  • Tidskriftsartikel (refereegranskat)abstract
    • The objective of this study was to increase the knowledge of local stakeholders acceptance of model-generated data when used as a communication tool in water quality management. The Ronnea catchment in the southwest of Sweden was chosen as the study area. The results indicate the model-generated data served as a uniting factor. Simultaneously, the stakeholders were concerned with presented data, the main problems being sources of pollution, which were not accounted for, lack of trustworthiness when measuring pollution, and the uncertainty of the impact of natural variation and delayed effects. Four clusters of factors were identified as influencing stakeholders acceptance of the model-generated data: confidence in its practical applications, confidence in the people involved in or providing material for the dialog (such as experts, decision-makers, and media), the social characteristics of the participants (such as age and profession), and the way of communicating the data (such as tone of communication, group composition, duration, and geographical scope of the dialog). The perception of the fairness of the practical application of given model-generated data was also an important factor for acceptance.

  • Law, Norms, Piracy and Online Anonymity – Practices of de-identification in the global file sharing community
  • 2012
  • Ingår i: Journal of Research in Interactive Marketing: Special Issue on Digital Piracy. - Emerald. - 2040-7130. ; 6:4, s. 260-280
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose The purpose of this study is to better understand online anonymity in the global file-sharing community in the context of social norms and copyright law. The study describes the respondents in terms of use of Virtual Private Networks (VPNs) or similar services with respect to age, gender, geographical location, as well as analysing the correlation with file-sharing frequencies. Design/methodology/approach This study, to a large extent, collected descriptive data through a web-based survey. This was carried out in collaboration with the BitTorrent tracker The Pirate Bay (TPB), which allowed us to link the survey from the main logo of their site. In 72 hours, we received over 75,000 responses, providing the opportunity to compare use of anonymity services with factors of age, geographical region, file-sharing frequency, etc. Findings Overall, 17.8 per cent of the respondents used a VPN or similar service (free or paid). A core of high-frequency uploaders is more inclined to use VPNs or similar services than the average file sharer. Online anonymity practices in the file-sharing community depend on how legal and social norms correlate (more enforcement means more anonymity). Research limitations/implications The web-based survey was in English and mainly attracted visitors on The Pirate Bay’s web site. This means that it is likely that those who do not have the language skills necessary were excluded from the survey. Practical implications This study adds to the knowledge of online anonymity practices in terms of traceability and identification, and therefore describes some of the conditions for legal enforcement in a digital environment. Social implications This study adds to the knowledge of how the Internet is changing in terms of a polarization between stronger means of legally enforced identification and a growing awareness of how to be more untraceable. Originality/value The scale of the survey, with over 75,000 respondents from most parts of the world, has likely not been seen before on this topic. The descriptive study of anonymity practices in the global file-sharing community is therefore likely unique.

  • Integrated Assessment of Agricultural and Environmental Policies – A Modular Framework for the EU (SEAMLESS)
  • 2008
  • Ingår i: Agricultural Systems. - Elsevier. - 0308-521X. ; 96:1-3, s. 150-165
  • Tidskriftsartikel (refereegranskat)abstract
    • Agricultural systems continuously evolve and are forced to change as a result of a range of global and local driving forces. Agricultural technologies and agricultural, environmental and rural development policies are increasingly designed to contribute to the sustainability of agricultural systems and to enhance contributions of agricultural systems to sustainable development at large. The effectiveness and efficiency of such policies and technological developments in realizing desired contributions could be greatly enhanced if the quality of their ex-ante assessments were improved. Four key challenges and requirements to make research tools more useful for integrated assessment in the European Union were defined in interactions between scientists and the European Commission (EC), i.e., overcoming the gap between micro-macro level analysis, the bias in integrated assessments towards either economic or environmental issues, the poor re-use of models and hindrances in technical linkage of models. Tools for integrated assessment must have multi-scale capabilities and preferably be generic and flexible such that they can deal with a broad variety of policy questions. At the same time, to be useful for scientists, the framework must facilitate state-of-the-art science both on aspects of the agricultural systems and on integration. This paper presents the rationale, design and illustration of a component-based framework for agricultural systems (SEAMLESS Integrated Framework) to assess, ex-ante, agricultural and agri-environmental policies and technologies across a range of scales, from field-farm to region and European Union, as well as some global interactions. We have opted for a framework to link individual model and data components and a software infrastructure that allows a flexible (re-)use and linkage of components. The paper outlines the software infrastructure, indicators and model and data components. The illustrative example assesses effects of a trade liberalisation proposal on EU's agriculture and indicates how SEAMLESS addresses the four identified challenges for integrated assessment tools, i.e., linking micro and macro analysis, assessing economic, environmental, social and institutional indicators, (re-)using standalone model components for field, farm and market analysis and their conceptual and technical linkage.

  • A goal oriented indicator framework to support integrated assessment of new policies for agri-environmental systems
  • 2009
  • Ingår i: Environmental Science & Policy. - Elsevier Science. - 1462-9011. ; 12:5, s. 562-572
  • Tidskriftsartikel (refereegranskat)abstract
    • The goal oriented framework (GOF) for indicators has been developed as part of a comprehensive research project developing computerised tools for integrated assessment of the effects of new policies or technologies on agricultural systems (SEAMLESS-IF). The ambition has therefore been to create an indicator framework where the environmental, economic and social dimensions of sustainable development can be related to each other in a consistent way. Integrated assessment tools rely on such frameworks to capture and visualise trade-offs (antagonisms or synergies) among indicators between and within the three dimensions of sustainable development. The specific aims of this paper are to (i) present the GOF (ii) present how the GOF can be used to select indicators within the integrated assessment framework SEAMLESS-IF and (iii) discuss the advantages and limitations with the proposed approach. We show that the GOF has several advantages. Its major rewards are its relative simplicity and the possibility to link indicators to policy goals of each dimension of sustainability and thereby facilitate the comparison of the impacts of the new policy on the different dimensions. Another important feature of the GOF is its multi-scale perspective, which will enable the comparison of effects of a new policy between scales. Yet, as typical for all indicator frameworks, the GOF has also biases either instigated by the issues the included models cover or by the stakeholders' selection of indicators. However, due to the way the GOF and its indicators are technically implemented in SEAMLESS-IF, it can easily be extended and include new indicators to increase and update its policy relevance.

  • A model-supported participatory process for nutrient management: a socio-legal analysis of a bottom-up implementation of the EU Water Framework Directive
  • 2011
  • Ingår i: International Journal of Agricultural Sustainability. - Taylor & Francis Group. - 1473-5903. ; 9:2, s. 379-389
  • Tidskriftsartikel (refereegranskat)abstract
    • A methodology for local stakeholders' involvement in water management using a catchment model as a platform for dialogue has been developed and tested in the Kaggebo Bay drainage area in the southeast of Sweden. The process involved farmers, rural households not connected to municipal wastewater treatment facilities, local and regional authorities as well as different water and agricultural experts. This paper aims to assess whether and how the methodology has succeeded in encouraging social learning and promoting action and which barriers can be identified. The assessment shows that the methodology is able to create confidence in the process and increase the willingness to act as the methodology was able to adapt the form and content of the dialogue to better fit the cognitive and relational needs of involved stakeholders. It is also shown that the process may lead to a probable improvement of the eutrophication situation. However, if these types of processes are to serve not only as a basis for social learning and action at the local level, but also as the basis for a broader process of societal learning, then a mechanism to confer local ideas to the regional and national levels has to be clarified.

  • Critical Load : The politics of chemistry
  • ????
  • Annan publikation (övrigt vetenskapligt)abstract
    • Critical Load was introduced as a environmental policy tool in the late 1980s in response to a need for exact and scientifically based measures to abate transboundary air pollution in the Convention onLong-Range Transboundary Air Pollution (CLRTAP). The main objective in this study was to analyse the practical operationalisation of these limits. The study proceeded by analysing policy document treating the Critical Load concept produced by the Swedish Environmental Protection Agency (SEP A) It is showed that the concept is mainly operationalised through three scientific disciplines, chemistry, ecology and toxicology. Chemistry dominates and two things are forwarded as a reason. First, the political over all aim of Critical Load is based on the ideas that nature is robust within limits a perception, which is closely entangled with an idea that it is possible to calculate these limits. This favours chemical explanations, as chemistry is perceived as more calculable than for example ecology. Secondly, the Critical Load concept was initially used in connection to acidification, which primarily has been perceived a chemical problem. As ecological  explanations in the material not are operationalised into precise limitsthe role of ecology is interpreted as a complement to the precise calculations provided by chemistry, taking into consideration the balance and the complexity of nature. Toxicological explanations on the other hand provide precise measurements and are therefore interpreted as an intermediary between ecology and chemistry. Thethree stories are therefore interpreted as versions on the same story,nature as robust within limits and calculable. The ecological and thetoxicological explanations are also interpreted as answers to a changein the perception of environmental problem to more complex and to achanging focus of polluting compounds in the CLRTAP.
