Vem är kvinnan på kvinnodagen? - en kvalitativ analys av Gomorron Sverige på internationella kvinnodagen
In this study we examine how the image of women, through framing and stereotyping in interviews, is constructed in the Swedish television morning show Gomorron Sverige on International Women?s Day. Our study is based on qualitative method, using the ECA (Ethnographic Content Analysis) model.Our main theoretical assumptions are that media contributes to constructing the images of reality we see in our heads, and that the images of women mediated through television are stereotypes which are displayed in the presenter?s questions and in the respondent?s answers. By defining the problems related to International Women?s Day, showing causal connections, making moral judgments and presenting solutions, television contributes to the viewer?s perception of what is important, why it is important, what is wrong and how to make it right.Based on our theoretical assumptions we have divided our study into three analytical themes:1.

Trä och fukt ? Mätmetoder för fuktrelaterade dimensionsförändringar hos trä och deras användbarhet, med två fallstudier inom konservering
This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.
Barnanpassade söktjänster på Internet
The purpose of this study is to investigate childrens possibilities to retrieve information by searching in searching engines designed for children. Two such search engines are examined: Yahooligans and Kids Click, both of which index pages in English only. I have compared Yahooligans with its equivalence for adults; Yahoo, by evaluating the retrieval effectiveness. Some functions in Kids Click and in Yahooligan are investigated. Seven class room studies are described in the prior research chapter.
Ämnesindexering av spelfilm
The aim of this thesis is to examine possibilities concerning subject access to fiction film, i.e. appropriate ways to describe fiction film for subject retrieval. Problems regarding subject indexing in general, and subject indexing of fiction film in particular, are identified, as well as the uniqueness of fiction film and film genres. Four types of subject aspects are discussed: form and genre, fictitious characters, setting, and general topics. Several guidelines, form- and genre lists, and subject headings lists are examined and treated as potential indexing tools.

"Det går inte att badda in elever helt" : - om lärares möjlighet att påverka förekomsten av självutlämnande elevtexter.
Several researches asserts that as teachers are responsible for the content of teaching and by formulating teaching "Why, ""How" and "What", that will also give signals to students about what is important knowledge. This essay addresses the difficulties teachers may face in terms of self-disclosure student texts and awareness of this in the design of teaching and writing tasks. Research shows that self-disclosure and self-therapy student texts exist and that teachers are experiencing a difficulty with regard to assessment and treatment.Through qualitative interviews examined seven teachers' design of any, to the student, self-disclosure information from curriculum and policy documents. Another purpose of this paper is to examine the extent to which teachers, through the information they give to their pupils, may affect the texts students submit. It turns out that the respondents are united in the belief that they, through their data, may affect the texts they receive from their students when they are the ones that control the content of teaching, and they agree that the curricula gives them a great choice for design data. The survey shows that the perception of the curriculum that will open up for self-disclosure texts differ as some of the respondents believe that the curriculum is very much about the students way to express feelings and opinions, while others believe that they may try to package this data in another purpose or exercise.
En komparativ studie av fem rankningsalgoritmer för query expansion
The purpose of this thesis is to compare five different ranking algorithms for query expansion. The algorithms compared are f4, f4mod, porter, wpq, and emim. This is done using a TREC collection, a selection of topics, and relevance judgements. Relative recall is measured before and after the expansion of the query. The study shows that all of the algorithms manage to increase the relative recall, f4 being the one most successful..
Bakom Fasaden
Although textbooks are scientifically proven that they are important and central to the school curriculum one should think critically about the content in textbooks - is it really compatible with the curriculum of following the textbook tradition? As a teacher there are different ways to reflect on which textbook to choose. It is important to compare several textbooks with each other and be aware that a textbook should follow the curriculum. A teacher examines many sections/topics in the textbooks, but in this paper only one section will be reviewed among four different textbooks. The section to be compared, in the paper, is the interwar period.

Query expansion med hjälp av en elektronisk tesaurus i en bibliografisk online-databas.
In this Masters thesis we investigate query expansion using an electronic thesaurus. We formed 30 topics from the library and information science field. For each topic three searches were made in the bibliographic database LISA Library and Information Science Abstracts via CSA Cambridge Scientific Abstracts. LISA has an electronic thesaurus attached. We used this thesaurus to form baseline queries, baseline queries expanded with synonyms, and baseline queries expanded with both synonyms and related terms.
IKT på fritidshemmet : En kvalitativ studie om pedagogers uppfattningar och erfarenheter om IKT på fritidshemmet
Information and communication technologies (ICT) are constantly evolving in today's information society. The school uses ICT as a teaching tool and it begins to be included at the leisure-time in school by the educators.Aim of this study is to examine how educators describe their perceptions and experiences of using ICT in the leisure activities. The questions is about how the educators use ICT, what they believe children learn of ICT, and which advantages and disadvantages they see with ICT at leisure-time in school.Through a qualitative approach, I have had my questions answered by six trained educators, five of whom are recreational educators and one who is a preschool teacher. These have individually answered my interview questions as an interview took place over a phone call, while the others answered the same questions by e-mail. The interview questions were open-ended questions that were formulated so the educators could respond so freely and fulfilling as possible.The survey shows that teachers use ICT in multimodal approach at leisure-time in school, both in informing parents and in activities with the children.
Ämnessökningar med kontrollerad vokabulär och naturligt språk: en jämförande studie med felanalys.
The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.
Expansion av sökfrågor med Svenskt OrdNät som termkälla
The purpose of this Masters thesis is to examine the performance of queries that are expanded by synonyms and hyponyms from Svenskt OrdNät, the Swedish version of the Princeton WordNet. Four different types of queries were constructed: a baseline query S1, the baseline query expanded with synonyms S2, the baseline query expanded with hyponyms S3 and finally the baseline query expanded with the synonyms and hyponyms used in S2 and S3. The terms for expansion were picked by hand. The queries were executed in the Query Performance Analyser QPA, a tool used in IR education and in experimental IR research for analysing and comparing the performance of individual queries. 20 topics from the test collection GP_HDINF were chosen for the experiment.
