KULTURV?RD & CIRKUL?R EKONOMI Att skydda befintlig bebyggelse och fr?mja en h?llbar utveckling i fysisk planering

This paper examines the opportunities and challenges of integrating conservation practice and the circular economy into practical planning processes. In recent years, the discussion of circular economy and its relevance in the sustainability debate has intensified. According to the Swedish Environmental Protection Agency, the transition to a circular economy is crucial to achieving the national and international environmental and climate goals as well as the global goals in Agenda 2030. Parallel to this, there is a long established heritage discourse that emphasizes the importance of preserving buildings and cultural environments as part of our cultural heritage. These two discourses have common goals, but they differ in how they present their respective arguments.

Trollhättans befolkningsmål: 70 000 invånare år 2030. En analys ur ett byggentreprenadföretags perspektiv

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Epidemiology of viruses in the livestock in Tanzania : a minor field study with focus on Peste des Petits Ruminants virus

Peste des Petits Ruminants (PPR) is a disease of major socioeconomic impact. It is an acute and highly contagious viral disease of small ruminants caused by the agent Peste des Petits Ruminants Virus (PPRV), a Morbillivirus closely related to Rinderpest virus (RPV) which was declared eradicated from the world in 2011. PPR has a high morbidity and mortality rate and is characterised by high fever, nasal and ocular discharge, pneumonia, necrosis and ulceration of the mucous membranes and inflammation of the gastrointestinal tract causing severe diarrhoea. The role of wildlife in the epidemiology of the disease is still unclear. The disease is currently affecting sheep and goat in 70 countries worldwide and this year (2014) FAO has announced a program to eradicate the virus by 2030. In Tanzania, the disease was first reported in 2008 and has since then spread to different parts of the country.

Soil carbon in small-holder plantain farms, Uganda : a comparison between agroforestry and non-agroforestry

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

Ekot från djupaste Afrika : En kritisk diskursanalys av nyhetsprogrammet Ekots gestaltning av konflikten i Goma, Demokratiska Republiken Kongo.

This is a critical discourse analysis of the conformation of the conflict in Goma, Democratic Republic of the Congo, as constructed by Ekot, a news-show on Radio Sweden. The ambition of this bachelor thesis is to examine the production of a Congolese conflict for a Swedish audience and to find out how the construction differences with and without a reporter in the field. To obtain this purpose the narrative is studied as well as the use of voices that define the conflict. The construction of proximity between Swedish audience and the Congolese event and the meaning of sound to stabilize the formation of discourse within foreign news is examined as well. To conform and explain foreign news it must be put in relation to a starting point.

Visuell Perception : En studie av visuella faktorer kring ett musikaliskt framträdande

The essay investigates the visual element as seen by the audience and artist to be of greatest importance to a musicalperformance. The study was conducted in the form of a field work which included doing interviews with artists, surveys of the audience and interpretive observations of live performance. The fieldwork was conducted in three different environments in which I found myself on the spot and performed the various stages included in the field work. It was done to create a surface that could be used in an essay, and through that use this material to compare and analyze my results and in the end be able to answer my questions. I started from eight different factors which all could beexperienced visually on stage.

Lättläst information i e-förvaltningens tid : En studie om lättläst information när myndigheterna satsar på webben

The overall aim of this thesis is to examine how Easy-to-Read information, used by governmental agencies, facilitates and limits the field of possibilities for the intended recipient, based on the information.This, in anera of e-government.The theoretical framework is based on two Foucauldian concepts governmentality and discourse analysis. Representatives from five Swedish governmental agencies have been interviewed and the results have been analyzed based on the following questions: (1) How do the representatives construct the category Easy-to-Read? (2) How do these representatives construct the recipients of Easy-to-Read? In order to broaden the understanding of Easy-to-Read, an important national level policy document, containing a summary of strategies and goals for e-government has also been analyzed based on the following questions: (3) How is the e-government constructed in the text? (4) How is the citizen constructed and positioned in the text? The collected material is analyzed using a discourse analysis inspired by Foucault.With the results from the interviews and the analyzis of the policy document, Easy-to-Read information has been discussed and examined as a technology to meet the needs of people with reading difficulties, putin an era of e-government.The findings of the study include the following: (1) The e-government is constructed as a service agency and the citizens are positioned as clients. Furthermore, the citizens are expected to participate digitally and be digitally competent. (2)Some of the representatives does not know, with certainty, to whom the texts are directed or if they are used.

Citeringsmotiv och forskningsevaluering inom kardiologisk forskning. En kvalitativ intervjustudie

The issue of using citation based indicators in the evaluation of science is widely discussed. Only recently did bibliometric indicators become one out of many means for the allocation of financial resources for scientific research at Swedish universities. The purpose of this thesis is to discuss the issue of using citations when evaluating science. The author studied the issue from the perspective of citers? motives.

Transformativt ledarskap - en förutsättning för produktivt teamklimat och egeneffektivitet?

In the faster growing pace of changes and competition in the global economy, factors promoting group effectiveness are of interest. How do components of leadershipstyle, especially transformational, team climate and selfefficacy correlate? To answer this question 3 questionnaires regarding leadershipstyle (MLQ), team climate (TCI-Short) and selfefficacy (self developed) were distributed to employees of a Swedish installation company (108 participants). Moderate positive correlations were found between climate and selfefficacy and between varying elements of leadership and selfefficacy. The leadership behaviour Contingent Reward correlated moderately with all climate dimensions and strongly with selfefficay.
