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 underlying purpose of this study is to see whether a library focused solely on providing literature in other languages than Swedish serves as a unifying, integrating force, or as an agent for division and exclusion. The study focuses on the International Library in Stockholm. The authors have created a profile of the visitors of the selected library, concerning their characteristics, their library habits and their perceptions of the International library. This profile has then been compared with the staff?s perception of the visitors as a group.

I denna uppsats undersöks hur lärare arbetar med skönlitteratur i skolan, dels i språkförberedande undervisning på IVIK programmet såväl som i svenska som andraspråksundervisningen och i svenskan med andraspråkselever. Syftet med uppsatsen är att studera vilka arbetsmetoder lärarna använder sig av med andraspråkselever, hur lärarna arbetar med ämnets syften och språkutvecklingen. En undersökning har gjorts genom intervjuer med fem lärare på en gymnasieskola. Utgångspunkten för uppsatsen är följande frågeställningar:Hur arbetar lärare med skönlitteratur i skolan, dels i språkförberedande undervisning på IVIK programmet såväl som i svenska som andraspråksundervisningen och i svenskan med andraspråkselever?Hur arbetar lärarna språkutvecklande i de skönlitterära momenten och hur ser man att det har uppnåtts?Hur arbetar lärarna med de skönlitterära syftena i ämnet och hur ser man att eleverna har tagit till sig innehållet i syftet?  Resultatet av undersökningen visar att arbetet i grupper med enbart andraspråkselever har ett tydligt andraspråksperspektiv.

Syftet med uppsatsen är att studera hur synen på det manliga och kvinnliga talspråket utvecklats från 1900-talet fram till början av 2000-talet och om denna utveckling även syns i elevers ageranden i skolan. De frågeställningar uppsatsen bygger på är: Hur beskriver och förklarar forskare från 2000-talet mäns och kvinnors muntliga språkbruk? Hur beskriver och förklarar forskare från 2000-talet pojkars och flickors muntliga ageranden i skolan? Kan de allmänna teorierna kring mäns och kvinnors muntliga språkbruk relateras till de muntliga ageranden som pojkar och flickor uppvisar i skolan? För att besvara frågeställningarna och leva upp till syftet har en litteraturundersökning genomförts. Forskningen som bearbetas i studien är från 2000-talet och representerar såväl samband mellan språk och kön, som samband mellan språk, kön och skola. Resultatet visar en generell attitydsförändring kring det kvinnliga och manliga talspråket, där de kvinnliga dragen idag värdesätts mer än tidigare.

The aim of this study is to examine social workers' and social work students' attitudes towards people living with hiv in Sweden. I will also examine if there is a connection between knowledge and attitudes. The questions at issue are how social workers' and social work students' attitudes can assume to influence on their professional practice and what causes can affect their attitudes towards people living with hiv. The study is based on a qualitative method. The methods have been: conversational interviews with five social workers, who work with family issues and integration, and a focused group interview with four social work students.

The goal of this work has been to create a flexible strategic group-based artificial intelligence for the Arrowhead Game Studios-game Magicka, by implementing, using and examining different AI-techniques that's used in many commercial games in more or less extent. C# is the programming language that has been used in the development, and the implementation has been made as flexible as possible to make further development and extending AI-rules etc. easier..

Uppsatsen utforskar människans psyke utifrån den franske psykoanalytikern och psykiatrikern Jacques Lacans psykoanalytiska teori. Uppsatsen undersöker subjektets förutsättningar och möjligheter utifrån lacansk teori, samt vilka implikationer det får på symptomets plats inom klinisk diagnostik. Metoden använder lacanskt teori som beskrivningar av subjektets status, vars framställning abstraheras till en rad regler. Teorins giltighet prövas i uppsatsen mot kliniska fallbeskrivningar och andra exempelfall. I diskussionen framkommer att implikationen av den lacanska teorin om subjektet är vittgående vad gäller kliniskt diagnostik och värderingen av symptomet. .

Detta är en kvalitativ studie om över- och underordning i heterosexuella pars vardag. Carin Holmbergs (1993) avhandling "Det kallas kärlek" är min största hjälp och det är från den jag hämtat större delen av de teorier jag använt. Holmbergs (1993) teorier om könsmakt är min utgångspunkt. Det var hennes avhandling som lade grunden och väckte mitt intresse för att göra en liknande studie. Jag gjorde fyra gruppintervjuer med en mindre observation.

The essay discusses the effects that changes to the office plan have on organizational culture. Information about actual change as well as expected change in organizational culture was gathered before the empirical research was initiated. The empirical research was carried out at the Customer Logistics department at Ericsson through: an interview with a manager in charge of the relocation and design of the office, a manager for the specified department and also five employees of this department. The empirical studies show that there was a significant change in organizational culture and that results were not always as expected. There was a loss in symbolic actions, which needed to be compensated for, a perceived reduction in spontaneous communication, and a mixed response of perceived change in social interaction.

The study deals with the beliefs that relatives of alcohol and drug dependent persons, and representatives from social services have to the various forms of support available for the relatives. Those who participate in the study points out that there are many people who have a need for support as a relative of an alcohol or drug addicted individual, but that there are circumstances that make them choose not to seek assistance. The study shows that the relatives can experience a reluctance to seek support from social services because of how the organization looks like. The study is qualitative, where the collection of the empiric material has consisted in six semi-structured interviews. Three of them have been with relatives of alcohol-or drug-dependent persons and three have been with social workers in various professions, whose work consists of helping both the relatives of people with alcohol and drug dependence as well as people who are dependent.

Prosody can be characterized as the rhythm and the melody of speech. Prosodic features convey emotions, thoughts and geographic origins of each individual. Spoken language without prosody would be monotonous, without variations in loudness and rate. Children with cochlear implants perceive speech in a different way than children with normal hearing. Consequently the speech produced by a child with cochlear implants may sound different.The purpose of this study was to examine prosodic skills in Swedish children with cochlear implants and to compare them with the prosodic skills in Swedish children with normal hearing.

This research aims to determine teacher perceptions on alcohol- and drug use among students, as well as how they implement the municipality framework against alcohol and drugs. The research was carried out in a midsized town in the centre of Sweden. It is characterized by an inductive approach and was performed through a qualitative method. Results were analyzed from a hermeneutic approach, and theories used are system theory, salutogenic approach and Mead?s symbolic interaction theory.

This thesis has the purpose that through a text analysis examine how four schoolbooks for high school treats the religions Judaism and Hinduism. The schoolbooks are from the years 2000, 2001, 2003 and 2009. The perspectives are from a religious viewing point, that means that the women are religious, Jewish feminists and Hindu feminists. The theories used are written by these women and are academic litterature.  The questions are how are women represented in the schoolbooks, is the feminist critique present or are the two religions represented and described in an invariable way, and is the description of Judaism and Hinduism consistent with the curriculum?The text analysis used in this examination means that reality is organized through and by the language used by the actors in that reality.

This paper is about basic set theory and cardinalities for infinite sets. One of the results are that the line R and the plane R2 contains exactly the same number of points. Because of that the set theory is described with a formal language this the paper has an appendix about formal languages..
