Biodiversity can be described as the total variation of life forms, where diversity ranges from gene level up to the ecosystem level. The diversity can be calculated in a number of ways, and this study use one of these methods. In this study empirical food webs have been used and analyzed, where eleven characters are defined and used as parameters to calculate the Euclidean distances between food webs that describe the variation that may exist within classes of terrestrial, marine and freshwater habitats. The class who stood out and showed the greatest diversity at the ecosystem level was the marine food webs, which showed a high value of the average euclidean distance. The other networks were not as distinctive and the average of the euclidean distance in these classes was comparatively low..

The aim of this study is to investigate the prevalence of computer consumption among boys in ninth grade, and to see if there were any differences with regards to physical activity, sleeping habits, breakfast habits and BMI. The study has cross sectional design with a comparative and a quantitative structure and is based on a former study called ?Food & Health 2007?.  The respondents were represented by 181 boys in ninth grade, recruited from ten different schools in the county of Uppsala, who were answering questions about media consumption, breakfast habits, physical activity and sleeping habits. Daily computer consumption was reported up to one hour for 12 % of the respondents, one to three hours for 65 % and over three hours for 42 %. The boys who had a high physical activity level were less frequent in computer consumption while those who had a low physical activity level spent more time by the computer.

This thesis aims to spread some light over the phenomena of gender construction in the upper secondary school. The background of this thesis is the gender gap in education. Girls are more successful in school and receive better grades than boys. The explanation that is given for this is that pupils are limited by far to rigid gender roles (DEJA 2010). The question is how these gender roles ? and specifically masculinity ? are constructed.

Previous studies have shown that economic sanctions have adverse effects on the level of human rights in sanctioned countries. The focus of research on the effects in sanctioned countries has left the question of whether economic sanctions can have a regional effect on human rights levels in countries not sanctioned in the same region. Therefore, this essay has sought to investigate if economic sanctions aimed at an individual state have a regional effect on the level of human rights in countries not sanctioned within the same region. A previous study found that economic sanctions in Latin America positively affected the level of human rights in non-sanctioned countries within the same region. This essay has examined whether the same result can be found in a region with a different level of democracy.

The purpose of this study has been to look into and analyze the view on sex equality in textbooks and teaching media, and teaching of a group of upper secondary school teachers, through a gender perspective. The teachers teach subjects within social- and political science. The two questions that I wanted to answer are: What views do the teachers have on sex equality in their teaching? What views do the teachers have on sex equality in the teaching media (textbooks and other teacher media) which they have access to? Since I wanted to look into the teachers own views I chose unstructured interviews as the method of gather empirical information. To interpret the transcribed texts I chose the hermeneutic view of people as intentional.

Gender is one of several factors that affect our society. According to the National Agency of Education and the values of Lpf 94, the school should communicate and counteract gender stereotypes. However, there is no demand for gender knowledge in the syllabus for Civics in upper secondary school.The purpose of this study is to investigate how two teachers work with gender in Civics education, with main focus on working practices. In addition, I wanted to investigate which conceptions students in upper secondary school have about gender in education. The method used is interviews.

Our modern swedish society is charactarized by peoples and cultures from all over the world. In this perspective I believe that young pupils of today need culture studies in school in order to understand themselves and further to recieve knowledge about different cultures, traditions and lifestyles. The present study is an attempt to investigate the potential of the ethnological culture analysis as a pedagogical method. The paper is divided into two sections; one in which I (a student teacher in swedish language training) have applied the culture analysis in a literary context. By using the culture analysis on Emily Brontë´s classic book Wuthering Heights I have tried to let typical elements from the Victorian era appear.

The aim of this thesis is to look for signs of students? understanding of algebra by studying how they make the transition from arithmetic to algebra. Students in an Upper Secondary class on the Natural Science program and Science and Technology program were given a questionnaire with a number of algebraic problems of different levels of difficulty. Especially important for the study was that students leave comments and explanations of how they solved the problems. According to earlier research, transitions are the most critical steps in problem solving.

In focus of this study lie students of an upper secondary school in a multicultural district, where more than 60 % of the students fail to reach the national goals for education. Since this particularly exposed group of students receives little attention during my studies in the Special Educational Teacher Programme, I have felt an ever growing urge to examine this group closer. As a basis for this study stands theories on how children and youths, in particular those of immigrant background, need holistic consistency and continuity in order to be able to build a positive development of identity. The purpose of this study is to explore the possibilities of developing parent cooperation in a multicultural district, through finding out what teachers and parents expect and desire from parent cooperation. I also want to find out how parents and teachers think that a working parent cooperation affects the student.
