Vilken betydelse har ett filialbibliotek? exempel Högsby

The purpose of the present thesis is to investigate the interaction between the branches in the different villages and its users and the importance of the branches for democracy. To illustrate these points, I have focused on Högsby municipality, a local council in Kalmar county. Högsby municipality is of particular interest in this connection, since all seven of the branches have been closed recently; only the main library remains. Moreover, three of the closed branches were, in 2005, taken over by citizen organizations local to the part of Högsby municipality where the libraries were located. The specific issues that were addressed were:- What needs were satisfied by the local libraries in Högsby council and is it possible to satisfy these needs in other ways and then, how?- Does the absence of a local library affect democracy?Interviews were performed.

V?GEN IN I EN KRIMINELL LIVSSTIL En kvalitativ intervjustudie om f?re detta kriminellas gestaltningar av v?gen in i kriminalitet

The aim of this study is to gain an understanding of former criminals' own experience of their entry into criminality and to identify and analyze the factors they use to explain their path into criminality. To study this area, a qualitative method has been applied with five semi-structured interviews of ex-criminals from an organization that works to help and support people who have previously been involved in crime by offering employment, education, and rehabilitation in order to be further integrated into society again. To analyze the respondents' stories about their way into criminality, the theory of social bond by Hirschi has been applied and contribute with insights in later criminal acts as well as the theory has been problematized to some extent. Today, there is a lot of research on different aspects that can explain the way into criminality in different aspects, on the other hand, research has largely been measured with a quantitative approach with statistics and self-reported data. This study therefore intends to apply a qualitative approach, where ex-criminals themselves describe their path into criminality.

Miniräknaren i dagens gymnasieskola

Arbetets syfte var att undersöka hur lärare använder miniräknaren i sin undervisning men även hur eleverna använder den och om det finns några skillnader i attityder och användning mellan elever och lärare. Undersökningen gick också ut på att se om användandet har ökat eller minskat i gymnasieskolan. Arbetet syftade också till att undersöka om det finns några skillnader mellan tjejer och killars attityder till miniräknaren och tjejer och killars användning av den. En lärarenkät och en elevenkät delades ut på fem olika skolor och dessa låg till grund för undersökningen. Resultatet pekar på en ökad användning, en mer positiv attityd till miniräknaren hos gymnasielärarna och att alla lärare, i någon form, tar hänsyn till miniräknaren vid prov.

Folkomröstningen som korrektiv : - en jämförande studie av riksdagens val av beslutsmetod i frågorna om EMU och EU-konstitutionen

Sweden has been a member of the European Union since 1995 and the power of the organisation to make decisions has increased over the years in a rate which hasn?t been followed by an equally increase in democratization. This is partly due to the lack of participation in the decision making process and at the national level the citizens don?t possess enough channels to compensate the loss of influence. To solve this democratic dilemma, more and more countries are turning to the referendum.

Den erfarne ripjägaren : Optimalt födosök hos homo sapiens?

The purpose of this study is to examine some factors that make a human grouse hunter to prolong and increase its hunting effort. The theory of optimal foraging is used for explaining their behavior.The data of this study is collected from a web-based inquiry from 2007 answered by grouse hunters in Sweden. The method that has been used is mainly bivariate statistics and logistic regression analysis.Key findings shows that an experienced grouse hunter has more than 5 times the chance of prolonging hunting effort when grouse density is high, compared to a beginner grouse hunter. On the same time experienced grouse hunters also stop hunting in advance when grouse density is low to a larger extent than inexperienced hunters. Other factors of importance for prolonging the hunting effort for a day are age and the travel distance to the hunting area.

Biblioteksrum i förändring: Folkbibliotekariers upplevelser av ny-, om- och tillbyggnation

The aim of this study is to examine how librarians experience implementations of changes in the physical space of the public library. The study seeks to answer the following questions from the librarians? perspective: What are the underlying reasons for changes in the physical space of the library? What are the important functions of the public library to the community residents? What reactions do librarians get from community residents after changes in the physical space of the public library? The study is based on semi-structured interviews with librarians working at seven small public libraries in Sweden. A model of four library spaces, which was developed by Andersson and Skot-Hansen in 1994 and refined in 2012, is used as a theoretical framework to help analyzing the results. The majority of the libraries are structured according to the older version of the model.

Optimering av B-stolpe

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
