LUS- och skrivutveckling

The purpose of this study was to compare reading development assessments with writing assessments to create an understanding about the relationship between the reading and writing ability of children. Another aim of the study was to look at other factors that cohere with the ability to read and write, such as background and socio-economic status. Our hypothesis was that explicit instruction in writing is necessary to develop good writing skills. We chose to conduct a quantitative study containing an inquiry, a dictation and a writing task. We compared our results with reading assessments based on a reading development schedule (LUS).

Lekflöde i Varbergaskogen : Affordans som synsätt vid formgivning av en naturslinga för barn

Drawing on earlier research, and using observations as the method, this study presents a design of a nature playscape for children. Applying outdoor pedagogy to the fundamental structure of a specific location, the study proposes a design of a playscape, over a more obvious design, for instance one based around a quiz walk.The theoretical framework is Gibson?s theory of affordance, and the goal has been to create a "play flow". The study concludes that spatial rhetorics can be an important tool when teaching children about nature..

"Det var fel, men vi brydde ju oss inte alls om de personerna" : En kvalitativ studie om hur svensk journalistik skildrar relationen mellan polisen och romer

The following study aims to examine how the Swedish journalism portrays the relationship between the Swedish police and the Romani people in Sweden in connection with the disclosure of the registration of thousands of Romani people during the autumn of 2013. The study proceeds from a series of articles written 2013 about what in Swedish media is known as ?Registerskandalen? or ?Romregistret?. The theories used in the study all originates from Postcolonial Theory and Ethnocentrism, and we used van Dijk's Critical Discourse Analysis for analysing the result. In the end of the study we find that the Swedish journalism portrays the Swedish police's view on the Romani people as negative in comparison to how they view the rest of the majority society in Sweden..

Problemet med Sverigedemokraterna : En studie i hur Sverigedemokraterna representeras i två svenska tidningar

The aim of this study was to examine how the political party Sweden Democrats is represented in two Swedish newspapers. The study included a national newspaper and a local newspaper, Aftonbladet and Blekinge Läns Tidning. We studied 35 articles from both papers, from 2005 and from 2009. We analyzed the texts using the linguist Norman Faircloughs (1995) method for discourse analysis. Based on his theories, we created our own model to examine the texts. Our model primarily focused on representation. The study was conducted at a time when Sweden Democrats was given much support in opinion polls and knocked on the door to the Swedish Parliament. The study showed that Sweden Democrats in both newspapers, primarily by descriptions, the choice of interviewees, etc., often are represented as racists.

En spindel i nätet? : Om specialpedagogers roll och förtrogenhetskunskap inom habiliteringen

This thesis is a qualitative study of a new law that was applied in December 2010. The law is called Lagen om etableringsinsatser fo?r vissa nyanla?nda invandrare, and is meant to help newly arrived immigrants that come to Sweden to establish themselves in the Swedish society. The aim of the study is to see what discourses the Swedish government produces as a result of this new law. Interesting for the study is to see what happens in the implementation stage at a local level, in this case in the municipality of O?rnsko?ldsvik.Theoretically and methodologically I emanate from critical discourse theory and institutional theory.

IT-tjänstefiering inom industrin : En studie om hur IT är värdeskapande vid tillverkningsindustrins övergång mot tjänsteorienterade affärsmodeller

The manufactory industry, due to decline in profit margins, is seeking new business opportunities by moving towards servitization and value-adding services in after-sales. We have therefore conducted a case study to investigate a manufacturing company in their current transformation towards servitization. By studying the management perspective, we aimed to understand how Information Technology, by adding value, could play a role in the transformation process. This study shows that information technology can take an integrating role, by supporting new value-adding services to provider and customer, as well as a co-creating role, where both provider and customer benefits by learning from each other, in the changing work process initiated by new services. The study has also shown that Information Technology, together with organization, information and people, are crucial components in the manufactory industry?s transformation towards servitization.  Furthermore, the study has also shown that the value chain has the potential to drastically change due to the value-adding that the information technology brings to the progress of servitization..

Mens : Himmel eller helvete?

The goal in doing this study has been studying public interpretations of media content in the commercials that this study uses. The analysis was based on two TV commercials for feminine hygiene products. Initially, they seemed to differ from each other, but soon the question whether or not they in fact did convey the same underlying message was raised. The theoretical premises on which the study was founded on are the gender perspective in advertising and the social construction of gender. To reveal the hidden signs appearing in these commercials and to find out their meanings, we used the method of semiotic analysis.

Biblioteksbloggen ? en studie om realisering av bloggverksamheter vid folkbibliotek

The purpose of this bachelor thesis was to gain a deeper understanding of and examine how library blogs are realized at public libraries together with the views among librarians regarding the realization of library blogs.The questions we wanted to answer were: ? How is the library blog realized at the public libraries in this study? ? What are the views among the librarians in this study regarding the realization of the library blogs?The analytical model in this thesis is Connie Crosby?s six steps on how libraries successfully can realize their blogs. Four of the six steps were selected: planning, implementation, marketing and measures of success. The methodology used for this study was semi-structured interviews. Two interviews were conducted with three librarians that have partial responsibility of their respective library blogs.The results of the study show that the process of the library blog can look different in different libraries, and that the respondents had clear views on how the realization of a blog should be done.

Bygga hus i traditionell härjedalsstil

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.
