A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Skärgårdsstiftelsen, which is responsible for several of the archipelago islands in Stockholm, has chosen to explore the possibilities for more sustainable heating systems in buildings on the islands in collaboration with KTH. A reduction of energy use and improving the efficiency of existing heating systems are included as part of the environmental work. This report studies the island of Grinda, which is located outside the area of Vaxholm in Stockholm. The study area consists of a guesthouse consisting of a restaurant as well as conference facilities and four neighboring cottages used for overnighting. The cottages now run solely on direct electricity, both for heating and hot water.

The essay has its beginning in the source material that deal with ancient Norse religion before the people in the Nordic countries became Christian. The fact that there are no contemporary written or authentic sources available that can tell us something about the Norse religion during the Viking age is problematic. Archeological source materials is available, but tend to talk more about power relationships and social status than the old Norse religion and the way people practiced their faith. Medieval Christian writers are a source of knowledge of the Norse religion; however, they can only highlight the Norse religion from a Christian point of view and ways of evaluating the pagan faith, making them less reliable.The written sources of this paper are based on the written by two medieval Christian writers, Saxo Grammaticus and Snorri Sturluson. These sources are among the first to treat the Norse religion process after the introduction of Christianity in Scandinavia.

Consumers are facing a wide selection of brands trying to get their attention. An increasing amount of corporations are incorporating non-traditional media in their marketing strategies as an attempt to build relationships with their customers. However, along with the new opportunities to enhance consumer emotions about the brand, social media has brought along new risks for corporations to face. This paper investigates the consequences of different ways of handling such electronic word-of-mouth (eWOM) crisis on Twitter. Furthermore, we investigate potential differences depending on the credibility of the source that sent the message.

The following thesis concerns the conceptualization of openness within the open access movement. Open accesscan be understood as a phenomenon or a movement that aims at changing the current system of scholarly communication.Consequentially, the movements goals arose in relation to the escalating serials crisis in scholarly communicationand the increasing power of commercial publishers. The purpose of the thesis is to study three centralopen access declarations with the aim of uncovering the different conceptualizations of openness found withinthese texts. Leaning on the theoretical position known as actor-network theory, the declarations role within a surroundingnetwork is explored by focusing on how openness as a concept has been produced and reproduced bycentral actors. Two overarching questions frames the study: How is openness conceptualized within the declarations?And how can openness, as a concept, be understood as an effect generated by a larger network?The first part of the study focuses on the first question.

Library and information science students often ask themselves if their education will be sufficient and adapted to the work tasks they will meet with as future librarians. It is the aim of this Master thesis to investigate LIS-graduates' experiences of the transfer from academic studies into professional life. The thesis thus treats four questions: I: What problems, if any, does the LIS-graduate experience when first employed? 2: Does the recently employed librarian feel that the academically obtained knowledge is applicable in professional life? And, if so, how does it apply? 3: Does the new employee find that there are areas in which his/her academic education has been insufficient? 4: What is the general attitude towards LIS-graduates' education among colleagues and is the library staff prepared to provide the necessary instructions? The investigation is performed through interviews with eight LIS-graduates, all of whom have recently started working as public librarians. The analysis is based on the concepts of competence, qualifications, work skills, knowledge and in the processes of formal and practical learning.

This essay deals with 18 year old boys´ experience of their usage of pornography. My main focus was the pornography found on Internet, which includes pornographic films and nude pictures.Both developmental and social psychological perspectives were applied in the study. These theoretical perspectives were chosen, because boys´ view of sex, especially during their adolescence, are influenced by the increased supply of porn and that boys understanding of porn are influenced by values present in our society. The methods used were three focusgroups and a short survey with simple questions regarding pornography. The choice of methods was based on my standpoint that an open discussion concerning porn was less offensive of integrity, in comparison of working with individual interviews.

I en stadsmiljö som innehåller stora mängder geografisk information på en begränsad yta finns det flera faktorer som ställer till problem vid kartläggning och positionering. Målet med detta arbete var att skapa en dynamisk stadskarta för webben med visualisering av byggnader i flera plan, att skapa ett användarvänligt gränssnitt med möjlighet till relevanta dataurval samt att undersöka vilka metoder som är användbara för positionering där en GPS-mottagare inte har täckning. Den metod som främst var av intresse att undersöka är en teknik benämnd WiFi Positionering, vilken med hjälp av trådlösa accesspunkter beräknar användarens position.Ett system för datalagring och tillhandahållande av data via ett webbaserat användargränssnitt dimensionerades och implementerades. De programvaror som användes till detta var PostGIS (databashanterare), GeoServer (kartserver) och OpenLayers (kartapplikation). Systemet installerades i en testmiljö som tillhandahölls av Compare Testlab.Användargränssnittet är ett webbaserat program vilket utvecklades med en teknik som stöds av webbläsare i smartphones samt till datorers dito.

The BA thesis Front Yard Gardens ? spatiality, design elements, expression and social aspects is a summary of the entrance and front yard garden phenomenon ? where the entrance is the set design and the designer is the director. The thesis touches the social context of which entrances have been and still are shaped. The various appearance of the entrance and front yard gardens throughout the history, starting with the first entrance by the edge of the wood and coming up to the front yard gardens of today, is described. It touches the present day through an analysis of some entrances and front yard gardens of modern residential areas.

The purpose with this work is to describe the language that is built around the chronic fatigue syndrome (CFS) in Sweden. Our questions are: What does the professional field look like; who writes, about what and for which kind of readers? How do they describe the expressions and the upcoming of CFS? For which reasons can CFS be considered as a medical diagnosis/illness? How can CFS be understood from a social perspective? Our theoretical starting point is a social constructive theory and also Karin Johannisson's theory about medicalization and Foucault?s theory about power. We have from a literature-exposition of Swedish articles from 1989 to 2006, done a social constructive discourse analysis with help from Laclau & Mouffe's discourse theory, and Fairclough's model of social practices. In our textual analysis we found three dominating discourses: A medical discourse, a social/cultural discourse and a general/popular discourse.

In the 1970´s the North American lodgepole pine (Pinus contorta) was introduced to Sweden in large scale. The lodgepole pine affects its new environment different from Scots pine (P. sylvestris), leading to a change in biological diversity. Forestry today affects the ground beetle fauna (Carabidae). Habitat specialists associated with older forests are first affected. When the canopy closes again after a clear-cutting species that prefer open habitats reduces and those who prefer mature/closed forests increase. In this study we compare differences in diversity and community structure of ground beetles in stands of lodgepole pine and Scots pine.

This study used a qualitative interview design to explore the experiences of seven Swedish female elite athletes and their career retirement. The athletes were engaged in three different sports; track and field (athletics), handball and golf and five of them are former professional or semi-professional athletes. The process of their athletic role exit was based on the theoretical findings of Ebaugh (1988) and her four phases: First Doubts, Seeking Alternatives, The Turning Point and Creating the Ex-Role. The findings reveal that for these female former elite athletes Seeking Alternatives already starts before the First Doubts and that possibly the athletes at an early stage have insights of the discontinuity of their athletic career. The importance of transferring their role residual to future paths in life was stressed among the female athletes in order to be able to have a smooth transition process.

Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affectson the environment compared to several other heating methods.This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.The results have thereafter been analyzed and discussed from different angles..

I denna uppsats undersöker vi ett antal grundförutsättningar som behövs för att uppnå en systemförvaltning som skall kunna stödja en organisations verksamhetsprocesser. Dessa grundförutsättningar som vi grupperat i föl- jande fem faktorer: affärsmässighet, organisation, styrning, förvaltning och processer har vi främst identifierat ur teorier kring systemförvaltning, pro- cessorientering och organisationslära. Undersökningen som genomförts på Luleå tekniska universitet har visat att alla dessa är viktiga för en fungeran-de systemförvaltning ur ett verksamhetsperspektiv..

The purpose of this thesis is to examine how academic librarians seek information for themselves and for others, and what differences exist. The terms self-generated and imposed information seeking is used to describe the two different types of information seeking. Step 2 ? define and understand the problem, step 3 ? choose a search system and step 4 ? formulate a query of Marchionini?s information-seeking model forms the basis of the theoretical framework, which is supplemented with Soergel and Katz. Qualitative interviews with eight academic librarians were conducted and analyzed in order to gather empirical facts.
