The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

The purpose of this essay is to critically review three different contributions to the agency ? structure debate from a political science perspective. My opinon is that the agency ? structure debate is one of the main problems within the social science. The theories which I will examine are Lennart Berntsons theory from 1974, Lennart Lundquists from 1984 and Walter Carlsnaes from 1992.

The aim of the study was to understand professionals? perceptions and experiences of adolescent stress. In the study I interested myself further if you can identify gender-specific patterns in the professional stories about young people's stress and stress related illness. Five interviews were conducted with professionals in psychiatry and social work. The thesis took its incipience in social constructionism.

Previous research shows that small workplaces more often discriminate immigrants during the process of hiring new employees than larger workplaces, and usually explains this result by referring to structural factors. At the same time, previous research also shows that self-employees tend to have different personality traits than other people. Could it be the case that the higher discrimination among small workplaces can be explained at an individual level? I examined the hypothesis through OLS-regressions using a survey called Employment, Material Resources, and Political Preferences. The results showed that people working at small workplaces tend to have more negative attitudes towards immigrants than people working at larger workplaces.

Background: Overweight is a health problem throughout the western world. Child health care (CHC) nurses and school nurses meet many children and their families and have the opportunity to work with prevention. The purpose of this study was to investigate the CHC - and school nurse´s experiences and reflections in the work on obesity in children. The aim was also to investigate the structural conditions CHC- and school nurse feel the need for this work. Method: The study had a qualitative approach with descriptive design.

Introduction: The health for individuals with intellectual disabilities is asubject that is prioritized by the Swedish Institute for Public Health. Socialsupport has been proven to be important for health and quality of life. Despitethis fact there is no research available regarding the influence social support hason health and quality of life for people with intellectual disabilities in Sweden.Aim: To describe social support and the consequence of social support forhealth and quality of life for individuals with intellectual disabilities. Method:A litterature review of research in a defined area with a descriptive design.Systematic searches for articles were done in several databases and ultimately16 articles were chosen. Themes and categories were created with respect to theaim of this study during the analysis of the articles.

According to Food and Agriculture Organization newsprint is defined as: Uncoated paper, unsized (or only slightly sized), containing at least 60 percent of mechanical wood pulp. The consumption of newsprint in Sweden was just over 798 000 tonnes in 2009, which represents approximately 90 kg per person. Although there are studies that predict a drastic reduction in newsprint consumption in the Western world, there seems to be a clear difference between forecasts for the future given by statistical analysis of newsprint consumption and forecasts given by experts in the industry. The former predict a continuing increase while the experts see a coming decrease in consumption.In this report, both demand and business strategies of newsprint in Sweden are studied. The study also presents a forecast of the future which is based on historical data and qualitative interviews.

The aim of the essay is to explore how so called ?safe spaces? are built, and the part that creativity can play in this construction. The essay also explores the duality of idea-based social work that at the same time strives to support vulnerable groups and strives to make social and political changes. The essay has its empirical base in the RFSL Ungdom project ?Tusen bilder, tusen ord? (A thousand pictures, a thousand words).

I have taught pupils in several schools in eighth and ninth grade in ?weak? groups in mathematics. Most of them seemed to possess potential, but lacked motivation. Even though I tried several pedagogical methods, these approaches failed to engage the students. This prompted thoughts that this may reflect a broader structural problem about the organisation of education in Sweden.

En billig och robust motor av stirlingtyp har konstruerats för användning i villor. Som energikälla används de heta rökgaserna från förbränningen i husets panna. Motorn driver en generator i permanent drift under den kalla delen av året då värme- och energiförbrukningen är som störst i vårt land. Under den varma årstiden finns den tillgänglig som reservkraftverk. Tanken är att stirlingmotorns värmare ska placeras i en villapanna för att ta till vara exergipotentialen hos dess höga temperatur.
