Show moreLCA has become an important method to study environmental impacts of human activities. Still, there are several methodological issues in LCA that can adversely affect the results reliability. Three of these issues relate to a) allocation, b) the representation of the time dimension and c) the interpretation of results in LCA. Uncertainties play a fundamental and underlying role for these issues. It is widely-agreed that correctly dealing with these different uncertainty sources is a vital step towards increasing the usefulness and reliability of LCA results. Practical ways to deal with uncertainty are needed. The aim of this thesis is to deepen the understanding of the uncertainty dimension of current LCA. By means of addressing different sources of uncertainty not yet addressed, with new methods, a clearer picture of the implications of different sources of uncertainty in LCA is provided. This thesis departed from broad domains of uncertainty including risk, uncertainty as conventionally described, ignorance and indeterminacies. The selected sources of uncertainty are in the domains of risk and conventional uncertainty i.e. those due to incomplete scientific knowledge and that are to some extent quantifiable. This does not mean that all can be known or quantified as ignorance and indeterminacies exist. Show less

Show moreWorldwide, refugees are increasingly living in uncertainty for undetermined periods of time, waiting for an enduring legal and social solution. In this article, I consider how this experience of waiting is perceived through and influenced by the ubiquity of transnational digital connections, which play a central role in Iraqi refugee households in Jordan. I draw on ethnographic fieldwork conducted among Iraqi refugees in Jordan’s capital Amman to further understand the use of digital technologies in everyday experiences of prolonged displacement. Waiting is an intrinsic affective phenomenon, colored by hope and anxiety. I argue that affective affordances—the potential of different media forms to bring about affects like hope and anxiety—enable Iraqi refugees to reorient themselves to particular places and people. As “no futures” are deemed possible in Jordan or Iraq, digital technologies serve as orientation devices enabling them to imagine futures elsewhere. Through the interplay of media forms, the Iraqi refugees refract their own lives via the experiences of friends and family members who have already traveled onward and who in their perception are able to rebuild a dignified life. Transnational digital connections not only provide a space for hope and optimistic ideas of futures elsewhere but also help to sustain one’s experience of immobility. I argue that using the imagination can be understood as an act of not giving in to structural constraints and might be crucial to making Iraqi refugee life in Jordan bearable. Show less
