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.

Previous research has shown that the psychosocial work environment and leadership have a significant influence on the employees work satisfaction. Still there is much to explore regarding the employees experiences about these two subjects. A qualitative approach was used in this study to increase the understanding of the employee´s experience of psychosocial work environment and leaders role affecting it. Eight semi structured interviews were carried out at two organizations with four interviews in each place. The data was transcribed and a meaning concentration analysis was conducted.

Recent changes in Swedish law suggest new groups of ?desired? labor migrants, which international students is an example of. Despite this, international students in Sweden have received little previous attention in the literature. The current study focused on international master students? experiences of job searching in Sweden and challenges they face in job searching, recruitment, and workplaces.

Denna kandidatuppsats behandlar det arbete som konsulter från tre konsultfirmor inom chefsutveckling bedriver. Syftet är attbeskriva och jämföra dessa tre konsultfirmors utbildningsverksamhet gällande ledare med särskilt fokus på ledarutveckling ochledarskapsutveckling. Detta syfte har brutits ner till tre frågeställningar för att besvara hur dessa tre konsulter uppfattar vadledarskap innebär, hur konsulter arbetar med utbildningsprogram för ledare gällande utveckling samt vilka likheter och skillnadersom finns mellan konsultfirmornas arbetssätt gällande utbildningsprogram för utveckling. Den undersökningsmetod som jagvalde att använda är kvalitativa intervjuer. Denna studie utgår vidare från en hermeneutisk ansats där det inte går att säga att detresultat som jag har tolkat genom teori och förförståelse är en absolut sanning.

I detta utvecklingsarbete ligger fokus på den fysiska miljön, dess betydelse och förändringen av den. Syftet med detta utvecklingsarbete är att skapa ett rum som utmanar barnens kreativa förmågor och utvecklar ett multimodalt arbetssätt. Med arbetet vill vi även fördjupa förståelsen för miljön och skapa en förändring. Vi har genomfört arbetet i en förskoleklass, där önskemålet om en förändring från ett outnyttjat rum till en kreativ ateljé och ett stimulerande dansrum fanns. Metoder som använts är: intervjuer i form av feedback, observationer och den fysiska miljöförändringen.

Companys usually have intern communication platforms where employees can gather information and communicate with eachother. These networks are not public which leads to less resources spent on development. If this network is also used as a work tool may inadequate usability decrease work effeciency. Thats why we, by using known design principles, evaluated an already existing network of this kind along with interviews and think out loud tasks for users. Four users had to do some tasks while they explained how they went through step by step to solve those. This report culminates into a couple of guidelines which can be used to create a user friendly network. The problems that prevented users to feel in control when working resulted in the following guidelines: Create shortcuts of frequently used functions.

Most of the sea areas within the European Union are overfished and the catches are estimated to be up to five times lager then the amount to achieve a sustainable fishery. In doing so, the management of EU's marine resources comes to be questioned. The purpose of this study was to analyze EU's administration of marine fisheries and to explore which steps that can be undertaken to counteract the negative trend. The questions of the study were: How does the EU administrate today?s marine fishery recourses? And: How can the problem whit overfishing be discouraged? To answer these questions a comparative analyses were used to compare and evaluate administrative systems.

The histiocytic diseases are generally rare in dogs and not much is known about the disease. The disease complex that includes both a reactive form and a tumour form, is however common in certain breeds, among them the Bernese Mountain Dog. As the literature is very limited on the subject of histiocytic diseases, my aim with this thesis has been to gather current knowledge of these diseases. I have also attempted to estimate the frequency of the diseases among the Swedish Bernese Mountain Dogs and investigate if they appear to be more common among certain families..

Det här arbetet utreder en alternativ metod för mätning av varvtal hos likströmsmotorer. Det är idag vanligt att man använder sig utav givarlös feedback i reglersystem för att nå lägre produktkostnader. Nackdelen med metoden, som utnyttjar den över ankarlindningarna inducerade spänningen (back EMF), är dålig precision jämfört med system med varvtalsgivare. Denna alternativa metod utgår ifrån att motorströmmen varierar periodiskt med varvtalet på grund av asymmetrin i motorn. Genom analog filtrering av motorströmmen samt digital signalbehandling som arbetar utifrån autokorrelation är det möjligt att skatta varvtalet utan givare.

Syftet med examensarbetet var att undersöka vad som kan förbättra Luleå kommuns anställdas arbetstillfredsställelse och därmed göra Luleå kommun till en bättre arbetsgivare. Genom användandet av en kvantitativ metod och semi-strukturerade enkäter söktes svar på frågeställningarna: Upplever arbetstagarna arbetstillfredsställelse och om så vilka faktorer beror det på? Vad anser arbetstagarna att en attraktiv arbetsgivare ska kunna erbjuda? Arbetets teoretiska bakgrund innefattar olika teorier om vad som leder till arbetstillfredsställelse. Resultaten visade att respondenterna upplevde arbetstillfredsställelse, men att de önskade mer feedback från ledarna. Det framkom även att en av de viktigaste faktorerna i arbetet var trevliga kollegor och att lönen behövdes förbättras.

Resultatet visar att lärarna tycker att surfplattan generellt är positivt attha i undervisningen.

Either if you are a company or a state owned organization, in our case Sodertorn University collage, it is very highly demanded and needed that there is a well-defined definition of the area you perform in. It is also highly recommended that you have an accurate and informal profile of the type of company you are and that you have an effective communication to your surroundings, so that they can perceive it the way the company wishes mediate the message. In this essay we have tried to explain the kind of profile Sodertorn University collage has, and how its current students perceive this profiling strategy.Sodertorn University collage profiles itself through three significant areas: the school claim themselves to be multicultural, multiscientific in an aspect when it comes to courses and programs, and as a school with an ambition to educate and form more critical thinking students. This has become Sodertorn University collages trademark and is quite significant for the school, something that we have examined in our survey among the current students. What we will examine in our essay will only be the two first mentioned components, multicultural and multiscientific programs and courses.We have also had the intention to do a comparison with an earlier essay from 1997 made by two economics students, and put our results in contrast to the earlier results since there were no previous research after this one.

The Division of Language and Communication at Chalmers uses a web-based language tool, named EngOnline, to teach English grammar. The language tool suffers from some shortcomings. These include stability problems and an outdated interface but, above all, there is no documentation. Because of the lack of documentation and EngOnline?s need of maintenance, the Division of Language and Communication has decided to replace the language tool with a new and well documented one.The new language tool was developed using an agile work process; detailed documentation was replaced with more efficient communication.

The 17th October 2014 the Swedish Armed Forces (SwAF) introduced an intelligence operation in Stockholm archipelago after receiving credible observations regarding illegal underwater activities. Following the data collection and associated analysis it could be stated with certainty that a foreign submarine had violated the Swedish territorial waters. Media depend on SwAF to provide them with accurate information due to the confidentiality in these matters and the general area of investigation is therefore how the actions of the Swedish Armed Forces, in the submarine incident 2014, were portrayed in the Swedish media. Newspapers and blogs of defense policy represent the media and the thesis is based on the theories constructed by Graham Allison, the rational actor, organizational behavior and governmental politics. Furthermore, it is relevant to examine if there are any similarities or differences in how the submarine incident is illustrated, and what may be the reason for any possible occurrences.
