Green consumption energy use and carbon dioxide emission
- 2002
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this thesis is to explore the quantitative potential to reduce energy requirements and CO2 emissions through changed patterns of consumption, given unchanged levels of consumption expenditure. The thesis question is analysed using a systems analysis approach which in this case means that life cycle assessment data on energy requirements and CO2 emissions related to household consumption are combined with a financial and behavioural analysis to make sure that the budget constraint is kept and that both the first and second order effects of adopting a green consumption pattern are analysed. The budget constraints are kept using a general linear model. By using marginal propensities to spend to direct the reallocation of saved or deficit money calculated utility is maintained as far as possible. Further, investigations explore the impact of individual household demographic characteristics and geographic context on household consumption patterns, energy requirements and CO2 emissions. The key result of this thesis is that changed household behaviour, choosing “green“ products and energy efficient technology will not make a big difference. What can be achieved in the short time perspective by adopting an almost completely green consumption pattern and energy efficient technology is a reduction of energy requirements by around 8% and CO2 emissions by around 13%. With a longer time perspective and further technological change that provides additional possibilities to move consumption patterns in a greener direction, the effect on energy requirements and CO2 emissions is still fairly small. By 2020, the potential to reduce energy requirements is around 13% and CO2 emissions around 25%. In the most extreme scenario (2050), the scope for reducing energy requirements is 17% and for CO2 emissions 30%. All these reductions will be outpaced by growth in income almost as soon as they are implemented. Of policy relevance the results reveal that very limited impact can be expected by a policy relying on greener consumption patterns, whether adopted voluntarily or as a result of incentives such as tax changes. Such a policy cannot achieve more than a small and temporary reduction to growth in energy requirements and CO2 emissions. It is also shown that, prescribing specific consumption patterns as a means of reducing energy requirements and CO2 emissions has to be done with care. This is illustrated by one of the experiments in which adopting a partly green consumption pattern, a green diet, in fact increased total energy requirements and CO2 emissions. This, and the results of all the other experiments show the importance of applying a systems approach. It demonstrates that life cycle data alone are irrelevant for assessing the total effects of adopting green consumption patterns. Further research on the potential to reduce energy requirements and CO2 emissions thus primarily needs to better capture system wide effects rather than to improve on, and fine tune the measurement of the energy requirements and CO2 emissions related to individual products.

Managing place and distance : Restructuring sales and work relations to meet urbanisation-related challenges in Swedish forestry
- 2020

Ingår i: Forest Policy and Economics. - : Elsevier. - 1389-9341 .- 1872-7050. ; 118

Tidskriftsartikel (refereegranskat)abstract
- Drawing upon interviews with representatives of all the major forestry organisations in Sweden, this paper explores how, in their sales and services, they work to overcome the growing distance between forest owners and forests. The results indicate that increasing distance to forest owners in terms of sales and services work is largely dealt with by reorganisation of the sales process. Through trust-building activities such as modifying office structure and local work processes, and use of new technologies such as personalised forest websites/apps, previously local trust-building processes are being deliberately digitized and implemented through new technology and, in some cases, offices in cities. However, the results also suggest that these processes potentially affect the way in which forest as a resource and a place is constructed and interacted with. For example, it can be treated as an object of desire that is produced and marketed; as a place of knowledge and expertise that produces specific social and sales relations; and as a place of production to legitimize modern industrial forestry. Through this, forest management is constructed as an economic or technical issue that can be managed at a distance from the property.

Everyday Mobility and Travel Activities during the first years of Retirement
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Mobility is central to living an independent life, to participating in society, and to maintaining well-being in later life. The point of departure in this thesis is that retirement implies changes in time-space use and interruption in routines, which influence demands and preconditions for mobility in different ways. The aim of this thesis is to explore mobility strategies and changes in mobility upon retirement and how mobility develops during the first years of retirement. A further aim is to provide knowledge of the extent to which newly retired people maintain a desired mobility based on their needs and preconditions. The thesis is empirically based on travel diaries kept by newly retired people, and qualitative interviews with the same persons, and follow-up interviews three and a half years later. The results show that mobility is a way of forming a structure in the new everyday life as retirees by getting out of the house, either just for a walk or to do errands. Many patterns of everyday life remain the same upon retirement, but the informants also merge new responsibilities and seek new social arenas and activities. As a result, the importance of the car have not changed, but it is used for other reasons than before. After leaving paid work, new space-time constraints are created which influences demands for mobility. The study further shows that “third places” become important, especially among those who live alone, as they give an opportunity to being part of a social context and a reason for getting out of the house. The follow-up interviews revealed that declining health changes the preconditions for mobility. Daily walks had to be made shorter, and the car had to be used for most errands to where they previously could walk or cycle. However, mobility can also be maintained despite a serious illness and a long period of rehabilitation.

Bättre framtidsutsikter? Blandade bostadsområden och grannskapseffekter : En analys av visioner och effekter av blandat boende
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Internationally, the effect of social composition in urban neighbourhoods on individuals’ life opportunities has been given increased attention both by researchers and policymakers. Socially mixed neighbourhoods have been seen by policymakers as a measure to create better prerequisites for social upward movement and increased social integration. The international debate on neighbourhood effects has mainly focused on the impact of concentrated poverty, but there is a growing body of literature that has also addressed the question of social mix policies. However, in the Swedish context the research on social mix policies and neighbourhood effects are still quiet limited. Hence, there is a call for research on the effects of the Swedish social mix policy. The purpose of the present thesis was to analyse the policy aim and the implementation of such policy, and to analyse the effects of socially and physically mixed environments. Can socially and physically mixed environments create better opportunities for youth and young adults? To analyse the effects of the neighbourhood environment on individuals’ socioeconomic careers, advanced multilevel analysis methods has been used. These methods offer advantages for analysing neighbourhood effects, which the ordinary regression model can’t provide, as it can separate effects belonging to different contexts. The internationally research on social mix policy has shown mixed results. For this reason there has been widespread debate among researchers on the effects of socially mixed environments. This thesis shows that although the effects are limited, the neighbourhood environments have a significant effect on individuals’ future prospects. Individuals who have spent their childhood in socially and physically mixed environments, in general, perform better in school, have a greater probability of enrol in higher education, a lower probability of being unemployed and better income development than individuals who have been brought up in resource-poor areas. The study also shows that the neighbourhood environments as well as mixed neighbourhoods have differential effects for different groups.

Tidskriftsartikel (refereegranskat)abstract
- Objective The purpose of this article is to explore learners' perceptions of using virtual patients in a behavioral medicine Massive Open Online Course (MOOCs) and thereby describe innovative ways of disseminating knowledge in health-related areas. Methods A 5-week MOOC on behavioral medicine was hosted on the edX platform. The authors developed two branched virtual patients consisting of video recordings of a live standardized patient, with multiple clinical decision points and narration unfolding depending on learners' choices. Students interacted with the virtual patients to treat stress and sleep problems. Answers to the exit survey and participant comments from the discussion forum were analyzed qualitatively and quantitatively. Results In total, 19,236 participants enrolled in the MOOC, out of which 740 received the final certificate. The virtual patients were completed by 2317 and 1640 participants respectively. Among survey respondents (n = 442), 83.1% agreed that the virtual patient exercise was helpful. The qualitative analysis resulted in themes covering what it was like to work with the virtual patient, with subthemes on learner-centered education, emotions/eustress, game comparisons, what the participants learned, what surprised them, how confident participants felt about applying interventions in practice, suggestions for improvement, and previous experiences of virtual patients. Conclusions Students were enthusiastic about interacting with the virtual patients as a means to apply new knowledge about behavioral medicine interventions. The most common suggestion was to incorporate more interactive cases with various levels of complexity. Further research should include patient outcomes and focus on interprofessional aspects of learning with virtual patients in a MOOC.

Mobilitet och tillgänglighet – framtidens resande
- 2016
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Trafikverket har gett TRUM (Transportforskningsenheten vid Umeå Universitet) i uppdrag att utreda framtidens mobilitet innefattande frågor såsom privatpersoners attityder och normer till resande med bil och däribland självkörande bilar, betalningsvilja, syn på ägande inställning till individuellt resande gentemot kollektivt resande, samt intressenters förväntningar på ett framtida tillgängligt transportsystem. Därutöver önskar Trafikverket ökad förståelse kring arbetssätt och metoder för att möta teknikutveckling och framtida mobilitet. Syftet med föreliggande rapport är att svara på dessa frågeställningar utifrån litteraturstudier och intervjuer.Det huvudsakliga underlaget för rapporten är en genomgång av litteratur relaterad till transporter, mobilitet och historiska såväl som framtida trender. Fokus har varit på persontransporter kopplat till människors beteende, samt vad privatpersoner, framtidsspanare och företrädare för bil- och teknikbranschen tror kommer att hända med personresande i framtiden. Utöver litteraturstudien genomfördes sex intervjuer under januari och februari 2016. Intervjuerna gjordes med syfte att öka förståelsen för hur människor resonerar kring mobilitet och transporter i dagsläget och hur de tror att vi kommer att resa i framtiden. Utifrån litteraturgenomgången och intervjuerna kan konstateras att attityder till elbilar generellt sett är positiva. Hinder för ett bredare genombrott utgörs av uppfattade prisskillnader, räckviddsångest och uppfattad brist på laddinfrastruktur. Som drivkrafter kan nämnas ökat miljömedvetande och alltmer positiva attityder bland flera olika aktörer, till exempel teknikutvecklare. När det gäller självkörande bilar är attityderna mer varierande. Bland annat lyfts säkerhetsfaktorer, tillgänglighet och det faktum att flera bilmodeller redan idag utrustas med olika typer av autonomifunktioner. Enligt olika bedömningar kommer koncept såsom Mobility as a Service och liknande att leda till förändrade attityder och normer när det gäller både privat och kollektivt resande. Avslutningsvis lämnas förslag på hur dessa och andra förändringar kan följas och förstås utifrån ett planeringsperspektiv. Olika metoder och perspektiv är viktiga för att skapa en bild över framtida utveckling redan idag, framförallt kopplat till de miljöutmaningar samhället står inför.
