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.

AbstractThis bachelor thesis deals with the close company rules in chapter 56-57 within the Swedish income tax law (IL). The purpose of this thesis is to analyse the outsider rule in 57:5 IL. If a shareholder or a family member works or have worked actively within the company within the fiscal year or the last five fiscal years then the partner has qualified shares and is to be taxed according to the special closed company rules.If an outsider, directly or indirectly, is a significant shareholder within the company, and directly or indirectly, are entitled to dividends then an active partner only has qualified shares if there is special reasons. When making the assessment regard must be made to conditions under the fiscal year or the last five fiscal years. There is special reason not to apply the rule if there are agreements regarding how the profit should be split or cross-ownerships between companies.If a taxpayer can show that an outsider own 30 percent of the closed company and has a right to dividends and there is no special reason to why the rule should not be applied then the outsider rule is applicable.

This is a study based on discourse theory in purpose to examine the border-politics ofthe EU. Since the EU step by step has developed into an area of free movement on capital, people and services, the external frontiers have been given prioritiy on the political scene. Development in recent years have put questions of foreign- and security politics on a supranational level, meaning that the EU-member states in a wider range now cooperate in these political areas.To handle the increasing ammount of (illegal) migration to the EU an independet agency, Frontex,was established 2005 in favour of coordinating the Member States in issues regarding bordersecurity. The focal point of this study is to critically examine the identity of Frontex by using Becks theory of risk combined with the theory of governmentality. By doing so I seek to highlight the relation between Frontex and the EU and also that of Frontex mission in relation to illegal immigration.

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.

This final thesis consists of an investigation of how suitable it is to vertically integrate forest in Swedish forest companies. Different strategies to obtain raw materials have been evaluated and the advantages and disadvantages have been weighted against each other. The investigations contain a number of interviews with represents from companies with different strategies and persons that in different ways have faced the question of issue. An account study of SCA´s forest ownership has also been performed. The benefits for a forest company to vertical integrate forest consist mainly of safety in delivery, control over the supply chain and company image.

Huvudsyftet med denna studie är att kartlägga vilka faktorer som påverkar i gymnasievalet. Frågeställningar som belyses är vilka faktorer som påverkar eleverna och vilka personer som är betydelsefulla. I studien diskuteras också skillnader mellan olika grupper som exempelvis kön. Metoden som valdes var enkätundersökning med elever i årskurs 9 som stod inför sitt gymnasieval. Resultatet visar att intresse och att programmet ska förbereda för högre studier är de faktorer som påverkar mest.

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.

Denna uppsats visar vilken påverkan infrastrukturprojekt vars mål är regionförstoring har på olika aspekter så som befolkningsmängd, utbildningsnivå, pendling samt inkomstfördelning. Detta genom studerande teorier som Human Capital Theory, Central Place Theory med flera. Men också genom genomförda intervjuer och insamlad statistik. Uppsatsen består av två huvudfrågeställningar, dels vad syftet är med Ostlänken och vad detta bygge kan innebära för Norrköping utifrån faktorer som befolkningsmängd, pendling, utbildningsnivå samt inkomstfördelning? Men också om det blev större inkomstskillnader i Strängnäs efter bygget av Svealandsbanan? Resultaten visar att större infrastrukturprojekt har en påverkan på vissa aspekter, speciellt utbildningsnivån, pendlingen samt inkomstfördelningen.

An efficient market implies that the use of fundamental analysis should not result in excess return, and that any return exceeding the market average can be explained by compensation for risk, accord-ing to The Capital Asset Pricing Model (CAPM). The focus of this study is to test whether the suc-cessful investment strategy developed by Piotroski (2000) generates excess return on American data, after risk adjustment by using Fama & French?s (1993) 3-factor and Carhart?s (1997) 4-factor CAPM. Initially we form stock portfolios based on companies characterized by high book-to-market values, additionally, we divide them into different performance classes by ranking them with Piotroski?s (2000) measure of financial performance, F_SCORE.

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.

I publika börsföretag kan kostnad eget kapital estimeras med hjälp av Capital Asset Pricing Model ? CAPM utifrån marknadsdata av dess aktiepriser. Eftersom marknadsdata saknas för ickepublika företag måste estimering av kostnad eget kapital utföras på annat sätt, varpå approximativa metoder utvecklats. Då inga av dessa metoder fungerar tillfredsställande har syftet i denna undersökning varit att utreda om Analytisk Hierarki Process kan användas för att utifrån redovisningsdata estimera den systematiska riskpremien för ickepublika företag. Undersökningen har sin utgångspunkt i Cotner & Fletchers (2000) användande av AHP för estimering av den totala riskpremien.

The starting point for this study is the situation for immigrants during the process of integration. This study aims to describe and discuss, with a broad approach, if certain information needs arises when immigrants meet the Swedish labour market and in such a case, do they use the library and how does the public libraries meet those needs. A secondary aim is to help increase the understanding of immigrants and forming a basis for further efforts by the libraries to improve services for immigrants and point at areas where there is a need for further research. - Which expectations and demands meets immigrants on the labour market and which library needs are possibly generated by this? - What services and range of material do the libraries offer immigrants and how are they marketed at the libraries homepages on the Internet? - Do immigrants from outside the western culture use the library and in that case how? Swedish human capital and Swedish social capability are identified as demands that are often held by operators on the labour market.

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.

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.

One of the most distinguishing features of contemporary globalisation is production fragmentation, a splitting up of the manufacturing of a good into several different stages. Production fragmentation creates new opportunities through vertical specialization; a country incapable of mastering the entire production process may specialize in the manufacturing of one separate part. The aim of this thesis is to examine to what extent international integration affects a country?s ability to engage in vertical specialization in an industry characterized by production fragmentation. The analysis focuses on the european integration process over the last decade, where countries in eastern Europe with relatively low labour costs have been integrated with more capital abundant western economies.
