The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

The purpose of my study is to investigate teacher?s perceptions of their mission in the preschool class, and how they work to promote children?s written language development. What methods and working methods they use to awaken curiosity and motivate children to read and write. I am using the qualitative research method to get answers to my questions. I have made four qualitative interviews with four teachers in preschool classes from different schools.My questions are:What conceptions does teachers have about their mission in a preschool class?What different methods and approaches does teachers use to stimulate and wake children?s curiosity for reading and writing development?The theoretical basis for my study is the socio-cultural perspective, where learning occurs in interaction.

Since the beginning of the 1990s, Swedish society has gone through a great change. Firstly with the personal computer and then with the internet moving in to everyday life, a new arena for interaction with society evolved. Work, education, doing bank errands and reading or discussing the news, just to name a few, now all take place in the virtual world online. Not to mention social media sites such as twitter, instagram or facebook, the last of which has over half of the Swedish population represented as members.   Companies, corporations, interest groups, political parties and politicians must be aware of the massive impact that a post spread through social media can have.    This thesis will, with the text analyzing tool, argumentation analysis, and on the theoretical platform of political communications theory, analyze three of the most viral Swedish political posts spread over 120 000 times each, to see if there are any combined qualities that point to the fact that there is a formula for getting a post to become a viral success on social media.    The main result showed that of the three posts analyzed, all were built up around a factual thesis, argued for with foremost example arguments, not only appealing to the logical branch of argumentation but also to the ethical, and that they tended to be of high relevance and sustainability. The conclusion must therefore be that these are all qualities that tend to be of relevance for making a political post on social media into a viral success..

National Agency for Education for the results of national sample results show that students with another mother tongue than Swedish have low results with a larger percentage than majority students.

Bakgrund: Prestationsmätning och utvärdering är ett ämne som varit under stor debatt desenaste årtiondena. Relevance Lost debatten som startades av Johnson och Kaplan i slutet av1980?talet, där den redovisningsbaserade informationen kritiserades som styrmedel, fickmycket stort genomslag i den amerikanska litteraturen. Nya teorier har under de senasteårtiondena växt fram som en lösning på de problem som kan uppstå när utvärdering skerbaserat på enbart finansiella mått. Framförallt de redovisningsbaserade lönsamhetsmåtten haren tendens att leda till beteendeproblem, något som fått samlingsnamnet ROI?beteende.Överensstämmer den amerikanska litteraturen med svensk praxis? Relativt lite forskning harskett inom området och vi finner det därmed av intresse att undersöka användningen i svenskatillverkande företag och presentera en mer nyanserad bild av användningen.Syfte: Syftet med studien är att kartlägga och beskriva vilka prestationsmått som används avföretag och vilka eventuella mät? och beteendeproblem som upplevs vid tillämpning avredovisningsbaserade lönsamhetsmått.

Through a case study, I wanted to find out what advantages and disadvantages local companies consider with scrum and what they think about its future. To find out what scrum is, I read the literature and scientific articles and then wrote surveys based on my thoughts. Further, I also wanted to find out if it?s possible to use scrum in a school environment and therefore I visited a high school class who used scrum in one of their projects. The result was good but could have been better as it requires more training of scrum to understand everything.

 Over the past ten years, the pupils' performance and grades has fallen and the number of competent to high school has decreased gradually. The Swedish school has been criticized and the role of the teachers has been questioned, among other by the media. In autumn 2007 Johannesskolan, one of Sweden's tenth worst schools replaced the ordinary teachers of Class 9A against eight of the country's "main" educators with the goal of the class to become one of Sweden's third major. The teachers have the autumn term in which to achieve the goal and the outcome will be measured by national tests in core subjects Swedish, English and Mathematics. The aim of this paper is to examine the role of the teacher's leadership in relation to the pupils' social and intellectual development, and identify common leadership of these eight educators.

Syftet är att undersöka hur lärare arbetar för att skapa en fungerande klassrumsmiljö för elever med koncentrationssvårigheter som går i normalstor klass, samt att undersöka hur skolor organiserar stödet för dessa elever. Dessutom vill vi undersöka vad lärare anser om inkluderande undervisning av elever med koncentrationssvårigheter i normalstor klass. Syftet är även att undersöka hur lärare värderar sina förmågor att kunskapsmässigt kunna stimulera dessa elever. Undersökningen är baserad på en enkätstudie som har genomförts i två kommuner inom Stockholms län. Av de 100 enkäter som skickades ut till lärare fick vi 63 respondenter.

This thesis in sociology was based on a qualitative research strategy. Its intention was to analyze how a specific county in the middle of Sweden work to make the integration process of the unaccompanied refugee youths, with a Swedish residence permit, as good as possible, the other intention was to find out the possible following of this work.Interviews were done and statistics were found, this later on became analyzed together with the theories. The basic theories were integration and class theory.The mainly finding in this study was that that the integration of the unaccompanied refugee children leads them into a lower society class of the Swedish community. This since these youth are more of less forced to follow some steps in the education, which for many of them will lead to that they are too old to apply to the national gymnasium in Sweden, and therefore they only get education though the introduction program, which is not leading to a graduation from the gymnasium. Because of this they are not getting the same chances to succeed with the same kind of education as youth on other programs in the Swedish gymnasium..

Transitions in focus were those between preschool-class and primary school, between grade three and four and the last between grade six and seven.In the 1960?th Swedish elementary school were devided into three levels; primary school, intermediate level school and upper level lower secondary school.

The purpose of this MSc thesis is to examine the retrieval effectiveness of two Web search engines with queries from the academic discipline of Classical Studies. The two search engines are chosen to represent two different types Google as a broad general search engine and Argos as a specialised search engine for the subject of Classical Studies. The search engines are compared for precision among the first twenty results returned for thirty queries. In order to avoid bias in the study, the queries are based on real users' information needs. Due to the subjective character of the concept of relevance, the study is performed with five different experiments with five different definitions of relevance.
