  • A Reconsideration of Two "Welfare Paradises" : Research and Policy Responses to Men's Violence in Denmark and Sweden
  • 2009
  • Ingår i: Men and Masculinities. - Sage Publications. - 1097-184X. ; 12:2, s. 155-174
  • Tidskriftsartikel (refereegranskat)abstract
    • This article compares the situation in Denmark and Sweden regarding research and policy making around the issue of men-s violence to women and children. It does so by drawing on two comprehensive reviews of academic and policy data in those countries that were part of a broader European Union-funded project. Although the picture emerging from this comparison is complex, the overall conclusion is that in Sweden over recent years many more examples can be found of a critical, power-oriented approach than is the case in Denmark.

  • Men and Masculinities in Europe
  • 2006
  • Bok (övrigt vetenskapligt)abstract
    • Reviewing the current state of knowledge on men and masculinities in II European countries, this book emphasizes both the differences and the similarities between them. Drawn upon are the outcomes of a recently completed study undertaken by the European Commission-funded Critical Research Network on Men in Europe. Contributions by some of Europe's leading scholars in the field are included, and special emphasis is placed on four key themes--home and work, social exclusion, violence, and health. A particular focus on the fundamental changes taking place in central and eastern Europe in the postsocialist period is provided, and questions of politics and ethnicity in contemporary Europe are addressed.

  • A longitudinal assessment of inter-sectoral participation in a community-based diabetes prevention programme
  • 2005
  • Ingår i: Social Sciences & Medicine. - 0277-9536. ; 61:11, s. 2407-2422
  • Tidskriftsartikel (refereegranskat)abstract
    • To understand the development of inter-sectoral participation in the three intervention municipalities of Stockholm Diabetes Prevention Programme (SDPP) case studies with a longitudinal assessment were conducted using the spidergram method, document analysis and group discussions. At three time points, the members of the local steering committees assessed the extent of participation from narrow to wide inter-sectoral participation in five key areas: planning, resources, leadership, network and implementation. Wide participation of various interest groups was recognised in planning and implementing activities whereas local resources, the representation of the leadership and the extent of the network were perceived as more restricted. Expert involvement varied during the programme period but was not regarded as exerting control over the local programmes. Participation within the local steering committees decreased, with a stronger focus on the project co-ordinator and other local partners in latter years. The extent of partner engagement increased due to focusing on activities approaching multi-sector collaboration and institutionalisation. Overall, communication and shared responsibility appeared critical in influencing both the development and perception of participation. In conclusion, to understand the dynamic process of participation at different times, areas and levels, the development and use of evaluation designs combining different methods and information sources throughout the lifespan of a project are recommended.

  • Upplevelser av budskap Fallstudier av hur användare upplever och förstår information i användargränssnitt
  • 2007
  • Licentiatavhandling (övrigt vetenskapligt)abstract
    • När användbarheten studeras av den information som presenteras i ett användargränssnitt på en datorskärm kan det framkomma vad som fungerar effektivt och korrekt. I sådana sammanhang förs sällan någon diskussion om hur den information som presenteras kommunicerar med en användare.Syftet med detta forskningsprojekt är att på ett generellt plan öka kunskapen om olika analytiska perspektiv för att studera den information som presenteras i ett användargränssnitt på en datorskärm, som ett led till att skapa begriplig information för människor. Mer preciserat är syftet att få en djupare förståelse för hur en informationslämnare kan kommunicera med en informationsanvändare genom den information som presenteras i ett användargränssnitt. Målet med forskningsprojektet är att presentera ett antal relevanta analytiska perspektiv som kan användas för att beskriva hur presenterad information i ett användargränssnitt kan kommunicera med en användare. Forskningsresultatet bidrar med ett ramverk som kan ligga till grund för ett analysstöd. Forskningsresultatet bidrar även med en ansats för framtida forskning inom området.Forskningsprojektet bygger på fyra fallstudier. Analysobjekten i fallstudierna utgörs av fyra olika användargränssnitt på datorskärm, vilka används inom olika myndigheter, organisationer och företag. Vartdera användargränssnittet och dess informationsdesign studeras med hänsyn till: informationslämnarnas önskemål och intentioner, informationsanvändarnas upplevelse och förståelse av information och kontexters påverkan.De slutsatser som dras är bland annat att informationsdesign i ett användargränssnitt på datorskärm upplevs och förstås av användare i samklang med inre, när och yttre kontext. Dessa kontexter kan studeras utifrån tre olika perspektiv, ett semiotiskt, ett retoriskt och ett narrativt perspektiv. En sådan analys kan framhäva den kommunikation som sker mellan de budskap som informationslämnaren vill berätta, hur den presenterade informationen i användargränssnittet arrangeras och komponeras och hur olika kontexter påverkar användarnas upplevelse och förståelse av den information som presenteras.

  • Integration of biofuel production into district heating - part I an evaluation of biofuel production costs using four types of biofuel production plants as case studies
  • 2014
  • Ingår i: Journal of Cleaner Production. - Elsevier. - 0959-6526. ; 69, s. 176-187
  • Tidskriftsartikel (refereegranskat)abstract
    • This paper evaluates the effects on profitability of biofuel production if biofuel producers would sell the waste heat from the production to a local district heating system. All analyses have been performed considering four different technology cases for biofuel production. Two technology cases include ethanol production which is followed by by-production of raw biogas. This biogas can be upgraded and sold as biofuel (the first technology case) or directly used for combined heat and power production (the second technology case). The third and the fourth technology cases are Fischer-Tropsch diesel and dimethyl ether production plants based on biomass gasification. Two different district heating price levels and two different future energy market scenarios were considered. The sensitivity analyses of the discount rate were performed as well.In the case of energy market conditions, the profitability depends above all on the price ratio between biomass (used as the feedstock for biofuel production) and crude oil (used as the feedstock for fossil diesel and gasoline production). The reason for this is that the gate biofuel prices (the prices on which the biofuel would be sold) were calculated assuming that the final prices at the filling stations are the same as the prices of the replaced fossil fuel. The price ratios between biomass and district heating, and between biomass and electricity, also have an influence on the profitability, since higher district heating and electricity prices lead to higher revenues from the heat/electricity by-produced.Due to high biofuel (ethanol + biogas) efficiency, the ethanol production plant which produces upgraded biogas has the lowest biofuel production costs. Those costs would be lower than the biofuel gate prices even if the support for transportation fuel produced from renewable energy sources were not included. If the raw biogas that is by-produced would instead be used directly for combined heat and power production, the revenues from the electricity and heat would increase, but at the same time the biofuel efficiency would be lower, which would lead to higher production costs. On the other hand, due to the fact that it has the highest heat efficiency compared to the other technologies, the ethanol production in this plant shows a high sensitivity to the district heating price level, and the economic benefit from introducing such a plant into a district heating system is most obvious. Assuming a low discount rate (6%), the introduction of such a plant into a district heating system would lead to between 28% and 52% (depending on the district heating price level and energy market scenario) lower biofuel production costs. Due to the lower revenues from the heat and electricity co-produced, and higher capital investments compared to the ethanol production plants, Fischer-Tropsch diesel and dimethyl ether productions are shown to be profitable only if high support for transportation fuel produced from renewable energy sources is included.The results also show that an increase of the discount rate from 6% to 10% does not have a significant influence on the biofuel production costs. Depending on the biofuel production plant, and on the energy market and district heating conditions, when the discount rate increases from 6% to 10%, the biofuel production costs increase within a range from 2.2% to 6.8%.

  • Integration of biofuel production into district heating – Part II an evaluation of the district heating production costs using Stockholm as a case study
  • 2014
  • Ingår i: Journal of Cleaner Production. - Elsevier. - 0959-6526. ; 69, s. 188-198

    • Biofuel production through polygeneration with heat as one of the by-products implies a possibility for cooperation between transport and district heating sectors by introducing large-scale biofuel production into district heating systems. The cooperation may have effects on both the biofuel production costs and the district heating production costs. This paper is the second part of the study that investigates those effects. The biofuel production costs evaluation, considering heat and electricity as by-products, was performed in the first part of the study. In this second part of the study, an evaluation of how such cooperation would influence the district heating production costs using Stockholm's district heating system as a case study was performed. The plants introduced in the district heating system were chosen depending on the future development of the transport sector. In order to perform sensitivity analyses of different energy market conditions, two energy market scenarios were applied.Despite the higher revenues from the sale of by-products, due to the capital intense investments required, the introduction of large-scale biofuel production into the district heating system does not guarantee economic benefits. Profitability is highly dependent on the types of biofuel production plants and energy market scenarios. The results show that large-scale biogas and ethanol production may lead to a significant reduction in the district heating production costs in both energy market scenarios, especially if support for transportation fuel produced from renewable energy sources is included. If the total biomass capacity of the biofuel production plants introduced into the district heating system is 900 MW, the district heating production costs would be negative and the whole public transport sector and more than 50% of the private cars in the region could be run on the ethanol and biogas produced. The profitability is shown to be lower if the raw biogas that is by-produced in the biofuel production plants is used for combined and power production instead of being sold as transportation fuel; however, this strategy may still result in profitability if the support for transportation fuel produced from renewable energy sources is included. Investments in Fischer–Tropsch diesel and dimethyl ether production are competitive to the investments in combined and power production only if high support for transportation fuel produced from renewable energy sources is included.

  • Introduction of large-scale biofuel production in a district heating system - An opportunity for reduction of global greenhouse gas emissions
  • 2014
  • Ingår i: Journal of Cleaner Production. - 0959-6526. ; 64:1, s. 552-561
  • Tidskriftsartikel (refereegranskat)abstract
    • In this study, cooperation between Stockholm's transport and district heating sectors is analysed. The cooperation concerns the integration of biofuel polygeneration production. A MODEST optimisation model framework is used, assuming various energy market and transport sector scenarios for the year 2030. The scenarios with biofuel production and increased biofuel use in the region are compared with reference scenarios where all new plants introduced into the district heating sector are combined heat and power plants, and the share of biofuel used in the transport sector is the same as today. The results show that the cooperation implies an opportunity to reduce fossil fuel consumption in the sectors by between 20% and 65%, depending on energy market conditions and assumed transport sector scenarios. If we consider biomass an unlimited resource, the potential for greenhouse gas emissions reduction is significant. However, considering that biomass is a limited resource, the increase of biomass use in the district heating system may lead to a decrease of biomass use in other energy systems. The potential for reduction of global greenhouse gas emissions is thus highly dependent on the alternative use of biomass. If this alternative is used for co-firing in coal condensing power plants, biomass use in combined heat and power plants would be more desirable than biofuel production through polygeneration. On the other hand, if this alternative is used for traditional biofuel production (without co-production of heat and electricity), the benefits of biofuel production through polygeneration from a greenhouse gas emissions perspective is superior. However, if carbon capture and storage technology is applied on the biofuel polygeneration plants, the introduction of large-scale biofuel production into the district heating system would result in a reduction of global greenhouse gas emissions independent of the assumed alternative use of biomass.

  • Corpses, maggots, poodles and rats Emotional selection operating in three phases of cultural transmission of urban legends
  • 2014
  • Ingår i: Journal of Cognition and Culture. - 1567-7095. ; 14:1-2, s. 1-26
  • Tidskriftsartikel (refereegranskat)abstract
    • In one conception of cultural evolution, the evolutionary success of cultural units that are transmitted from individual to individual is determined by forces of cultural selection. Here we argue that it is helpful to distinguish between several distinct phases of the transmission process in which cultural selection can operate, such as a choose-toreceive phase, an encode-and-retrieve phase, and a choose-to-transmit phase. Here we focus on emotional selection in cultural transmission of urban legends, which has previously been shown to operate in the choose-to-transmit phase. In a series of experiments we studied serial transmission of stories based on urban legends manipulated to be either high or low on disgusting content. Results supported emotional selection operating in all three phases of cultural transmission. Thus, the prevalence of disgusting urban legends in North America may be explained by emotional selection through a multitude of pathways.

  • Poverty Prefers Company
  • 2014
  • Ingår i: Social Psychology and Personality Science. - 1948-5506. ; 5:3, s. 319-325
  • Tidskriftsartikel (refereegranskat)abstract
    • In three web-based experiments, we show that both actual poverty and experimentally induced (imagined) poverty create a preference for greater inequality. Study 1, a cross-national comparison between Americans and Swedes, showed that respondents who were actually poor and those who were experimentally induced to imagine that they were poor tended to express a heightened preference for greater inequality, and for a higher proportion of poor citizens. Study 2 replicated the effects using different procedures. Study 3 showed that imagining oneself being poor increases preferences for a greater proportion of poor people, but imagining oneself being rich does not increase preferences for a greater proportion of rich people. This poverty prefers company effect might affect support for policies aiming at reducing the number of poor people.
