Abstract [en]

Time-use diary data convey information about the activities an individual wasengaged in, when and for how long, and the order of these activities throughout the day.The data are usually analyzed by summarizing the time used per activity category. Theaggregates are then used to determine the mean time use of a mean individual on anaverage day. However, this approach discards information about the duration of activities,the order in which they are undertaken, and the time of day each activity is carried out.This paper outlines an alternative approach grounded in the time-geographic theoreticalframework, which takes the duration, order, and timing of activities into consideration andthus yields new knowledge. The two approaches to analyzing diary data are comparedusing a simple empirical example of gender differences in time use for paid work. Thefocus is on the effects of methodological differences rather than on the empirical outcomes.The argument is made that using an approach that takes the sequence of activities intoaccount deepens our understanding of how people organize their daily activities in thecontext of a whole day at an aggregate level.

Energianvändning som konsekvens av vardagslivet
Abstract [en]

Energy use is a part of everyday life and the use of energy is a part of the global climate change. Policy makers urge individuals to change their daily behaviour in order to mitigate climate change and care for our common environment.

The dissertation regards daily behaviour as activities performed by individuals. The theoretical base is the time-geographic approach wherein everyday life is regarded as a sequence of interlinked activities performed by indivisible individuals. The dissertation investigates individuals’ energy use as an outcome of the activities they perform in everyday life.

The empirical base of the dissertation is time-diaries from the Swedish time use survey 2010/2011. The diary data is explored as sequences of daily activities by using sequence analysis and clustering. The results show that individuals’ energy use is closely interweaved with how they live their everyday lives in terms of activity sequences. The results imply that changing an activity affects both the intricate web of interaction in the household and the interdependence of activities in everyday life. Change does not only affect the singular activity that was the object for the change, but rather major parts of the sequence of activities. In order to address energy conservation in information campaigns considerations ought to be taken on how everyday life is shaped and formed by the individual, by negotiations between the individuals in households, and societal structures. Information can be targeted to groups of individuals  with similar activity sequences as they are revealed by cluster analysis.

Abstract [sv]

Energianvändningen är en del av vardagen likaväl som användningen av energi är en del av den globala klimatförändringen. För att mildra effekterna på vår gemensamma miljö uppmanas människor av politiker och andra beslutsfattare att förändra sitt vardagsbeteende.

I avhandlingen betraktas vardagsbeteendet som människors dagliga aktiviteter. Avhandlingens teoretiska grund är den tidsgeografiska ansatsen, där människors vardag betraktas som en sekvens av de aktiviteter som utförs av odelbara individer. Människors dagliga sekvens av aktiviteter undersöks för att ta reda på vilken energianvändning som genomförandet av aktiviteterna ger upphov till.

Den empiriska grunden för avhandlingen är tidsdagboksdata från den svenska tidsanvändningsstudien från 2010/2011 och avhandlingen utforskar tidsdagböckerna som sekvenser av aktiviteter med hjälp av sekvens- och klusteranalys. Resultaten visar att individers energianvändning är nära sammanvävd med de aktivitetssekvenser som visar hur vardagslivet levs. Resultaten pekar vidare på att förändringar av enskilda aktiviteter också påverkar andra aktiviteter i det dagliga livet. Förändringar av en aktivitet påverkar således hela den dagliga sekvensen av aktiviteter. I utformningen av information som syftar till att minska hushållens energianvändning bör hänsyn tas till hur vardagslivets aktivitetssekvens formas av den enskilde i samspelet både med andra individer i hushållet och med samhällsstrukturerna. Målgruppsinriktad information kan utformas med utgångspunkt from människors likartade aktivitetsmönster så som de framgår genom klusteranalys.
