This thesis evaluates and compares the retrieval effectiveness of the two search engines Google Scholar and Scirus, which both specialises in indexing scholarly material on the web as well as journal articles. Thirty search queries are used and the first twenty retrieved documents for each query are examined for topical relevance and scholarly content. The search queries are based on legitimate information needs taken from a scientific questionbox on the web. Queries are expressed with advanced search operators and are the same for both search engines. Precise relevance criteria are set up and a binary scale is used when judging.

This paper is a comparing study of the retrieval effectiveness of the search engines Google, Google Scholar and Scirus. The aim is to find out how good they are at retrieving relevant academic material in the research-field of Library and Information science. The thirty search questions where based on actual information needs collected from exams within the field of Library and Information Science. This method was used to prevent that none of the search engines were given an advantage because of construction of the information needs. The first twenty retrieved documents on the retrieval lists are examined for academic content and relevance.

This thesis examines the retrieval effectiveness of two Web search engines. The two search engines are chosen to represent two different types Google as a broad general search engine and Dogpile as a broad general metasearcher. Twenty queries have been used and the first twenty hits for each query were evaluated for relevance. The queries were invented by the authors, based upon their interests and information needs. They were expressed in a general manner, by using one or several keywords, in accordance with the simple search mode available for each search engine.

The law which makes the purchase, or the attempt to purchase, temporary sexual services a criminal offence has been implemented in Sweden for more than six years. It appears as if very few, possibly no, sex-selling women have used the law to report men who have bought their services during these years. How can this be understood? With this thesis I suggest a new way of thinking on agency. A way which questions the traditional view on action whereby agency equals to act in certain, predefined ways.

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

The purpose of this study is to investigate the medial portrayal of Romani people in the newspaper Dagens Nyheter from 2013 and 2014. In the theoretical chapter the concepts of new racism is used to speak of what is considered racist in the Swedish society today. Other concepts that are used are type and stereotype which are used to explain how our context is depending on distinctions to understand what surrounds us. Concepts such as myths and binary-oppositions are other theories that are used in this study.  Six debate articles have been selected to investigate how the Romani people are represented.

Denna studie syftar till att undersöka hur gymnasielärare förhåller sig till och värderar kanon och intermedialitet, samt hur de implementerar dessa begrepp i undervisningen av litteraturhistoria. Bakgrunden till vårt arbete behandlar främst kanon- och intermedialitetsbegreppens historiska utveckling, forskningsläget definierar sedan dessa utifrån ett forskningsperspektiv. Undersökningen bygger på kvalitativa intervjuer med sex stycken gymnasielärare i en medelstor, västsvensk stad. Vi använder oss vidare av en hermeneutisk ansats för att redogöra för och analysera undersökningens utfall. Resultatet visar att det finns tydliga kopplingar mellan forskningsbakgrunden till vårt arbete och utfallet av undersökningen.

The municipality of Olofström is intensifying the co-operation with Sölvesborg and Karlshamn, the two other municipalities in the west of Blekinge. They co-operate in two local federations and for the moment negotiations are going on about a third local federation in continuation school, but the municipalities do not agree. The aim of this thesis is to examine why Olofström co-operate with Sölvesborg and Karlshamn, if there are any problems and where the limit of this co-operation is. The method in the thesis is qualitative interviews with local politicians and officials and an actor-structure-perspective is used. The result shows that Olofström is a municipality where the population is decreasing, and it has lost state subsidy during the last decade.

The North-American sociologist Michael Lipsky has characterized social workers as street-level bureaucrats with a substantial discretion in the relationship between the welfare state and its citizens. Within Lipsky´s theoretical framework social workers appear as a powerful group that socializes the citizens to uphold certain expectations towards the welfare state and its (re)distributional programs. From this point of view, it is important to learn more about social workers and the attitudes they express towards the welfare state. The aim of this study is to analyze how the welfare-political attitudes of future social workers are affected by their social background (e.g. class background and ancestral homeland).

The industry of management training programs is increasing rapidly. Every year numerous organizations sponsor expensive management training programs for their managers, hoping that this will pay off and make the organizations more profitable. The companies that offer these management training programs could be seen as important conveyers of conceptions of leadership. Thus, the purpose of this thesis is to identify similarities between a number of management training programs and see how they are related to different leadership theories , and based on this try to recognize the conceptions of leadership that are conveyed. The study is of qualitative nature and is based on interviews with representatives from five management training companies in Sweden along with a text analysis of written material presented by the companies.

The aim of this M.A.-thesis in social work is to problematize the assimilatoric concept of integration and its discourses in a postcolonial perspective in relation to social work in Denmark.As a support theory I use symbolic interactionism. By using these theories I show how the concept of integration and its discourses, when its aim is assimilatoric, can be understood and problematized with concepts as Binary oppositions and hegemony.It is shown that the construction of the discoursive other is a useful term as an instrument of interpretation of power in general. The relevance to social work in relation to the social workers double powered positions, professional and cultural power to define 'the other', in social work with ethnic minorities is shown in relation to the post colonial perspective with support of symbolic interactionism. The white western world hegemony and the social workers power positions in relation to the clients fits to the theoretic frame chosen in the thesis.A second aim in this thesis is to point to new ways for social work and to the necessity to reflect over a globalized world characterized by international migration, ethnic relations and diversity..

The purpose of this thesis is to evaluate three search engines with regard to retrieval effectiveness of information specific to Swedish users. Coverage and the precision in result descriptions are also examined. The three selected search engines are Google, MSN Search and Svesök. 30 queries were tested against the search engines and the first 20 result descriptions and results were judged for relevancy. Relevancy was judged by a binary scale.

The purpose of this thesis is to evaluate and compare the retrieval effectiveness of two search engines on the Internet: Svensk Medicin and Google Scholar. Svensk Medicin is a medicine-specific search engine and Google Scholar specialises in indexing scholarly material. A set of 20 questions in four categories were used to conduct the searches with the search engines. Genuine medical information needs were selected from a question collection provided by the television program Fråga doktorn. The relevance of the first 10 retrieved documents was judged by using a binary scale and the measure used was precision.

The purpose of this essay is to investigate modern influence in the painting Strömkarlen, by Ernst Josephson. Strömkarlen was painted 1884 in Norway. First the essay performed an investigation of earlier researchers statements to establish a ?common truth? that puts the painting in a realistic/naturalistic-romantic context. With the help of Yve-Alain Bois? model, where he sees art from the painters point of wiew, it was possible to use two articles, written by Ernst Josephson in the fall of 1884, where he debates the conditions for art and artists in Sweden.

The purpose of this study was to investigate different relations between the damages of falls and background variables as well as the relation between the falls and the weather condition to later be able to use this report to expand the knowledge among workers at VTI about the pedestrian fall injuries. All of the fall injuries in the data that this study is based on have occurred in Sweden during the time period between January 2003 and December 2011.To be able to answer the questions that this report is based on several statistical methods are used. The statistical methods that have been used during the making of this report are multiple linear regression, binary logistic regression, correlation analysis, association analysis and descriptive statistics as well as visual analysis.The results of the study show that women around menopause age have a tendency to get a big increase in the amount of injuries compared to men of the same age. The study also suggests that men on average tend to have a lower level of injury compared to women.Age also seems to affect both the amount of injuries and the level of injury negatively. The study suggests that the most likely reason for this is both that the intake of ?Fall Risk Increasing Medicine?, which is medicine that increases the drowsiness, is higher among older individuals as well as lower estrogen levels among older women and lower amount of testosterone among older men, which causes a loss of bone density in both sexes.The weather seems to have a strong effect on how many injuries occur but also a noticeable effect on the scale of the injury.
