The purpose of this study is to examine the difference between three query strategies with respect to retrieval effectiveness. The thesis aims at examining how two types of noun phrases containing a modifier to the head word, which is a noun affect the retrieval performance with regard to recall and precision. The noun phrases in the thesis are of two types: 1) noun phrases containing a modifier to the head word (which is a noun) and which are not dictionary phrases (NF) and 2) dictionary phrases. Both types of noun phrases in this thesis contain at least two words. The queries were executed in Query Performance Analyser, QPA, containing the InQuery system and a sub collection of TREC-Uta documents with its topics.

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.

The aim of this study was to investigate whether there is a correlation between birth order, academic performance and need for achievement. 166 students from Alvesta Gymnasium/ High school and Växjö Fria Gymnasium/ High school participated in the study. The result showed a significant correlation between birth order and study result, but unlike previous studies this study showed that it was the youngest siblings that had the best academic performance. Furthermore, a significant correlation between academic performance and need for achievement was found, also that higher need for achievement results in higher academic performance. The study also showed that there is a significant correlation between birth order and need for achievement, and it is the youngest children that have the highest need for achievement.

The aim of this study was to investigate how the content of the syllabus for Physical Education and Health at Uppsala University correlates to selected parts of the core content of the Gy11 syllabus for Physical Education and Health 1 in Upper Secondary School. Furthermore we aimed to investigate the perceived competency of recently graduated and still studying teachers of Physical Education and Health within the selected parts of the core content.The selected parts of the core content are:Exercise, sports and outdoor activities that develop a comprehensive physical abilityThe adjustment of tension and mental training.The methods used were a qualitative comparative text analysis of the syllabuses for Physical Education and Health at Uppsala University and Gy11 Physical Education and Health 1 in Upper Secondary School, as well as a quantitative survey conducted with recently graduated and still studying teachers of Physical Education and Health.The results were that there is an obvious correlation between the content of the syllabus for Physical Education and Health at Uppsala University and the Gy11 syllabus for Physical Education and Health 1 in Upper Secondary School. Moreover the survey shows that the respondents felt confidence in their ability to teach exercise, sports and outdoor activities that develop a comprehensive physical ability. The survey also shows that the respondents felt less confidence in their ability to teach the adjustment of tension and mental training..

This paper was part of the ongoing cooperation between the Swedish Civil Aviation Authority and the Department of Psychology at Lund University. The purpose of this study was to develop a self-report measure regarding human factors, for the air traffic controllers to fill out before they start their working shift. This in order to aid the team leaders in their judgment regarding the air traffic controller's ability to perform at the right safety level. The self-report measure would also serve as an aid for the air traffic controllers who have a responsibility regarding their own performance. If successful this self-report measure would make it easier for the air traffic controllers to be alert regarding certain factors that can have a large impact on their performance.

AimThe aim has been to describe the goals and the pedagogic model concerning physical education in the Waldorfschool.

How does the teacher do to achieve the goals in the Lpo 94?MethodA literature research of relevant previous studies was made among others in the database Eric.Curriculum for the Waldorfschool and books about Waldorf pedagogics and the teaching roll has been studied.

Children and youth inactivity and sedentary at school is increasing. This means that some of the students have a significant unhealthy lifestyle with physical inactivity, which in turn implies risks of suffering from various diseases, including obesity, type 2 diabetes and cardiovascular disease, all related to a sedentary lifestyle. To prevent illness, it is important that children and young people early get a positive attitude towards physical activity.The purpose of this study was to study the causes of child and adolescent physical inactivity in school, based on teachers 'and parents' perspectives.A qualitative research has been selected. To achieve the study objectives, the author has conducted seven semi-structured interviews, with an appropriate choice of five teachers and two parents with children in school. Data was analyzed with a manifest content analysis.The results show that teachers and parents felt that physical activity is a protective factor for children's health.

Introduction: We are facing an aging population, which means that the incidence of age related diseases, such as Alzheimer's disease, are expected to increase. In the current situation there is no cure for the disease, whereupon it is important to develop preventive strategies. Objective: To examine the association between Alzheimer's disease and physical activity. Method: A systematic literature search was done to identify the current state of knowledge from the year 2006 onwards. The reason for this limitation was that the SBU commissioned a systematic literature review in 2006, where the relationship between physical activity and Alzheimer's disease could not be determined.
