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.

Background: To be better able to meet the new competition, companies are seeking new competitive advantages, wich is forcing them to review and, in time, change both working methods and corporate structures. This has led to an increased interest in the development of strategies within the field of Knowledge Management. Objective: The objective of this thesis is to improve understanding of how learning in a company occurs over internal boundaries and to investigate whether individuals need to be motivated in this regard. We also aim to give recommendations as to how this can be developed. Furthermore, we will work out a model that explains the learning process.

 AbstractBackground: Among elderly people with dementia pain is a common problem. In older persons, particularly those suffering from dementia and cognitive impairment pain is often underdiagnosed and undertreated causing unnecessary pain, suffering and affect quality of life negatively. Dementia complicates the identification of pain when the natural ability to communicate decreases when a person is suffering from dementia. It is important that health professionals working with older persons with dementia are aware of the person?s pain expression.Aim: To clarify how older persons with dementia communicate pain expression.Method: To study this area a literature review was used.

När byggbranschen för några år sedan fasade ut de tidigare nationella regelverken och ersatte dem med de gemensamma europeiska konstruktionsstandarderna, Eurokoderna, ändrades processen för att brandskydda konstruktioner. Hur dimensionerings­processen ser ut med de nya reglerna är inte helt enkelt att sätta sig in i. Därmed har detta examensarbete framställts på uppdrag av Sweco Structures AB.Huvudmomentet i arbetet är beskrivning och förklaring av de befintliga dimensioneringsmetoderna. För att förstå metoderna från regelverken består de första kapitlen i detta arbete av grundläggande teori för brandens verkningssätt och stålets respons vid förhöjd temperatur. Detta följs av en genomgång av de förenklade beräkningsmetoderna och dess ekvationer.

Earth science is a dynamic system science that explores the structures and processes of the earth. Knowledge about the earth is important for citizens since the science is a vital part in the sustainable development of the society. Without good basic knowledge the citizens don?t have the possibility to anticipate in the questions and decision-making that concerns e.g. anthropogenic climate change. In the Swedish school system earth science is not an independent subject until academically studies at the University?s.

The main purpose of this study has been to survey the pupils? general comprehension of the content and aim of Swedish as a subject in upper secondary school and their attitude towards the subject. Furthermore the study aims at discerning whether there is a distinguishable difference between programmes with vocational and academic character.The study is based on the results of 101 answers from students in an opinion poll handed out at a Western Swedish upper secondary school. Throughout the analysis the results of the two programme groups have been weighed against each other. The result of the survey shows that:? The understanding of the aim and content of Swedish at upper secondary school is acceptable as a whole.

The Sand Catcher                                                       The thesis project The Sand Catcher investigates the encounter between permanent structures and an ever-changing landscape. The migrating sand dune Råbjerg Mile in northern Denmark is 40 meters high and moves more than 15 meters every year. By introducing a solid structure on the site, the fast movement of the sand dune is emphasised and thereby our view of time and space.Through intuitively building models with varied openings and densities I investigated how architectural elements react with sand. From these experiments a series of spatial features and effects were found, generated from the meeting with the sand.The Sand Catcher is a solid and permanent structure. The sand is the liquid element that generates new spaces, circulations and experiences.

The Public Sector Scorecard (PSS) is a younger version of the balanced scorecard, created for public and nonprofit organizations. The latest model of PSS is divided into three main groups and seven perspectives, while the balanced scorecard consists of four perspectives. Organizations who use either PSS or the balanced scorecard are supposed to have a clear vision spread all over the unit. This study has sought differences between the two models of financial control in both theory and practice. The first part of the study is a theoretical comparison between the models? structures and terms used in them.

The purpose of this bachelor?s thesis is to examine video games, gamers and gaming from an information science perspective. The purpose of the study is partly to study video games as a type of information system and partly to study gamers information use, information seeking and also the experience of gaming. A selection of five games have been analysed using a topology for video game analysis created by Espen Aarseth. A quantitative investigation has also been made, in the form of a web survey distributed through four Swedish online forums, the result of which was analysed using Carol Collier Kuhlthaus model of the information seeking process.

Remote work has become increasingly widespread due to advances in digital technology and changing organizational structures, a shift initiated by the COVID-19 pandemic. The purpose of this study is to examine how leadership influences employee motivation in remote work environments. The aim is to deepen the understanding of which leadership styles are most effective in maintaining and enhancing motivation when traditional psychical interaction is absent. To investigate this, a qualitative research approach was applied, consisting of semi-structured interviews with both individuals in leadership positions and employees. The findings indicate that leadership plays a crucial role in shaping employees' motivation in remote contexts.

Introduction: Sleep is necessary for human survival. Difficulty sleeping occurs in about one in four adult person in Sweden, insomnia in every ten. There are several reasons for difficulty sleeping, where stress is one of the most common. The quality of life and health are affected negatively. Treatment with proven efficacy against insomnia is not only sleep medication, but also cognitive behavioral therapy, CBT.

The aim of this paper is to examine the American movie trailer particularly its history, marketing and functions, presented as an historical overview from the serials of the early 1910s to the trailers of today. A trailer from each decade of the twentieth- and twenty-first centuries is selected which represent typical trends and shows how trailers historically functioned, including their formal, generic differences.The introduction focuses on the market in which the trailer operates, and raises the issue of the entertainment value of art or marketing, how the film industry works and to role of advertising. The second part of the introduction focuses on the development of film stars, and their importance in trailer campaigns. This brings in the question of the growth of Hollywood and new media forms/technologies. The manner in which new media also create a new type of audience is considered, which demonstrates how the trailers capture audience attention in new ways.The second part of the paper focuses on the history of the trailer and examines typical structures, of the different periods.The third part analyses how different trailers operate, and how the trailer industry stands at the beginning of a new era, the so-called Post-interactive era, which is discussed with regard to Spider-Man 2 and The Da Vinci Code..
