This thesis addresses the corporate sustainability process and different tools to assist the process of generating corporate strategies towards sustainability in the energy sector. The focus of the research was in backcasting approaches. The main outcome of the work is a framework for corporate sustainability for the energy sector. The framework is constructed around a three step strategic plannin
In order to meet the demands of globalization, universities across the world are in the process of managing issues of multilingualism (Doiz et al. 2013; van der Walt 2013). In Sweden, since the passing of the Language Act in 2009, state-funded universities are obliged to use Swedish as their official language while also becoming increasingly internationalized. While the Language Act makes Swedish
This paper describes a longitudinal study involving a woman who developed aphasia as the result of a stroke in 1991. Her language and communication abilities have gradually improved, but the biggest improvements have taken place after she began using a digital camera in 1997. The paper describes both changes that have been objectively measured, such as the number of words in her vocabulary and her
This paper examines the value to Swedish citizens of reducing the risk for salmonella bacteria in chicken filet. The contingent valuation (CV) study is based on the results of a postal questionnaire that was distributed to 2 000 randomly selected Swedish citizens aged 18-74. The valuation format used is a stated preference double bounded dichotomous choice. We employ the non-parametric Turnbull Lo
Popular Abstract in Swedish Markfosfor och mångfald av växter i svenska gräsmarker – en populärvetenskaplig sammanfattning Olika typer av gräsmarkshabitat innehåller en stor och viktig del av mångfalden av växtarter i Skandinavien och i norra Europa. En stor del av arterna är knutna till kulturlandskapet och des's äldre hävdformer. Förändringar i användning och skötsel av gräsmarkerna under detThe semi-natural grassland habitats contain an important part of the plant diversity in Europe. Changes in farming practices have lead to drastic decreases in plant species richness. The aim of the present thesis is to contribute to the knowledge about mechanisms governing the plant species richness in grasslands with emphasis on soil nutrients. Most species rich grasslands are found on soils with
The damage caused by the worldwide increase in natural disasters is staggering, with the poor and marginalised slum communities being the most vulnerable. This paper analyses the key variables and their causal relations underlying the complex system of risk and disaster occurrence in slum areas in El Salvador. Slum dwellers’ views and knowledge are the focus of this inquiry. A better understanding
This paper presents a 28 GHz QVCO intended to be used in an 81-86 GHz E-band transceiver. E-band transceivers using e.g. 16 QAM modulation schemes are sensitive to I/Q phase error. Already a three degree error significantly degrades the bit error rate, and careful control of the phase error of the 28 GHz QVCO is therefore required. In the presented design the phase error can be tuned using four va
Aim: The aim of this study was to explore and understand the complexity of ageing in relation to factors of importance for extending working life. Method: Discourse analysis of documents was used in an integrative review including 128 articles. Result: Four different conceptualisation of ageing are shown to affect older workers’ ability to extend their working life: (a) biological ageing people’s
A description of general models for adsorption kinetics is given. Combinations of the models are compared with adsorption data for the self-associating proteins β-lactoglobulin A and B, from Elofssonet al.(U. M. Elofsson, M. A. Paulsson, and T. Arnebrant,Langmuir,submitted). The adsorption onto methylated silica surfaces was measured by these authors by ellipsometry in phosphate buffer (0.01M,pH 7
