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 purpose with this essay is to compare two classes in an international school during their mathematic lesson. The international school offers education to their pupils in two languages; in Swedish and in English. Through this study I want to find out how teachers are working with language and communication during school hours. I will compare the work of two teachers and two classes to find out the differences and similarities between their work methods concerning language and communication during mathematic lessons.The main questions for the essay:How do the teachers work with language and communication in this school during the mathematic lessons?What similarities and differences are there between the two teachers in matter of methods of working with language and communication during the mathematic lessons?The research is based on interviews with the teachers and also on observations in the classroom during mathematic lessons.

The purpose of this qualitative research study is to examine if and how the teachers from a multicultural International School work with intercultural pedagogy. The school in question isprofiled and consists of both Swedish- and English classes. The study examines if and how the teachers related to the great variety of cultures and created opportunities for integration between the students and handling with values at school. It is important to be aware as a teacher to be able to take an active part in working towards a school that gives possibilities for different cultures to meet. If this is neglected, it may increase the risk of problems and cultural clashes between the students.

In this examination project I look into what ways upper secondary school students conceive themselves as politically influenced before they voted for the general election of 2010. The purpose is to examine which influences the upper secondary school surroundings and the classes of civic education are contributing with to students before they voted. As a method, I have used personal, semi-structural interviews on eight upper secondary school students who all voted for a party represented in the parliament. I have asked questions about how they believe their parents, the surroundings of their school and the classes of civic education have influenced them. To separate which influences primarily the upper secondary school and the classes of civic educations have had on the students, I have selected two comparison groups of four students in each.

The aim of this thesis is to find a statistical model that sort logs according to a predicted modulus of elasticity on the sawn boards. The input parameters for the model are X-ray variables from an X-ray scanner. For some of the log classes sawn at the sawmill it is desirable to have a narrow distribution of modulus of elasticity on the sawn boards. 250 pine logs from five different diameter classes were numbered and followed through the sawmill process. Log data were collected from X-ray and 3-D scanners in the log intake.

Earlier investigations showed that damages on timber from feeding rolls could be within the lower classes of damage according to VMRs classes. Knowledge about differences in productivity between kind types and aggressive types of feeding rolls is necessary because it should influence the question about damages on timber caused by different feeding rolls. In this study the production and timber damage in a harvesting head were evaluated at three levels of pressure (8, 10 and 14 MPa) on the feeding rolls, and with three different types of rolls. One type, the rubber cushioned steel plate roller had 10 mm studs and rubber damping, one ?middle? type made of solid steel with 14 mm studs, and one aggressive type, also made of solid steel with 18 mm studs.

The purpose of this essay is to explore how social media affect the political orientation and commitment of youths. Three scientific questions highlight the purpose from different angles. The didactic perspective is discussed in the initial and closing discussion, and is analyzed in the corresponding chapter. Two methods are involved in the study; one survey and one interview with a focus group. The survey had a total of 98 respondents from four different classes, all in the first grade of upper secondary school.

The purpose of this thesis is to illustrate the conception of creativity. Observation and interview illustrate teachers´ views of the concept, as well as the use there of. Classes in ensemble and aestethics have been observed. The reason for choosing these two classes is to give the investigator the oppurtunity to observe several students at the same time and it also makes possible for the investigator to observe several instrumentalists´ use of their instruments. Interviews have been conducted with teachers in the observed classes.

AbstractBy finding out the pupils' choice of strategies for problem solving, we as teachers, can get a better understanding of their way of thinking, and thus also help them develop in their learning of mathematics. In a classroom environment where several different strategies could be found, the pupils' learning is facilitated as they, with the help of classmates, find positive and negative attributes of different kinds of strategies. The pupils are, in other words, each other's resources, rather than competitors. The main point is that the classroom environment, as well as the role of the teacher in the classroom, are both key elements for good mathematics learning.In order to increase the understanding of the pupils' choice of learning strategies, a survey was performed based on two school classes, one third grade and one six grade class at the same school. Both classes received the same mathematical problem to work with, and the strategies observed were analyzed and compared.

The aim of this study is to investigate the notion of pupil influence in English teaching at level 1 and 2 at High-School level.

Empirical data has been collected through questionnaires from two classes at year 1 and two classes at year 2 in English. The study also includes interviews from four teachers and four students. The study is both qualitative and quantitative.

 Why is it that we still live in a society where an individual's social background plays such a big part in their chances of reaching a higher education? Despite the numerous educational policy reforms, especially in Sweden, it still seems that an individual's career choices are pretty much related to what kind of social class they grew up in. Sociologist Pierre Bourdieu claimed that social class is reproduced in the school system, and that students from the lower classes are much less likely to reach a further education than students from the middle or upper classes due to injustice in the school system. One thing that plays a big part in this "Catch-22" situation is the concept that Bourdieu calls habitus. Habitus could be explained as an individual's taste, knowledge, ability to master the spoken language, etc. Your habitus is manifested in the choices you make, the music you listen to, how you dress and the way you speak, and it determines your relation to the education system and life in general. As part of my essay, I wanted to interview students from lower or working class at my school, Konstfack, to see if they have had any negative or positive experiences from their encounter with a higher education. And if so, could they be linked directly to their social background? As a reaction to my own and my interviewees? experiences and frustration, I use the concept of habitus in my practical work.

The aim of this thesis was to analyse BARO WOOD AB:s timber measuring and quality sorting and to evaluate the analyse program Stockholmen. The purpose was to get a better understanding for the quality sorting made at BARO WOOD AB today, analyse differences in center board quality from logs with a good quality and logs with a bad quality, suggest new sorting criterias developed from analyses made with Stockholmen and to evaluate the program Stockholmen. All analyses are based on data gathered in a test sawing made at BARO WOOD AB in June and July 2002. The test sawing was made on four different diameter classes and every diameter class consisted out of A or M-grade logs, with a better quality, and B-grade logs with a lesser quality. The logs where sorted out with BARO WOOD AB:s existing quality criterias.
