Objective: The aim of the study is to describe pupils' understanding of the mathematical concept of function. How do pupils define the concept of function? What images of the concept of function evoke when they solve tasks, which involve identifying and constructing functions?Theory: A student's thinking about a mathematical concept depends on more than just the formal definition of the concept; therefore Tall and Vinner introduce the term concept image to describe the role cognitive structures play when students learn about concepts. The cognitive structure includes all mental images, associated properties and processes that an individual associates with a given concept. According to Sfard, an individual's understanding of mathematical concepts may have different character: an operational conception, where a concept is conceived as a process and a structural conception, where the given concept is conceived as an object, that is, as a whole.Method: 16 pupils at the Science Program at two different upper secondary schools inSweden answered a questionnaire on the mathematical concept of function.

This study was based on a quantitative method to examine gender-related attitudes towards leadership styles among employees in trade union organizations in Sweden. The aim of the research was to investigate and understand how gender relates to attitudes regarding leadership within these organizations. The study was based on research questions related to preferences for different leadership styles and the impact of gender on these attitudes. The study incorporated previous research and relevant theoretical frameworks such as leadership theories, gender theories, and theories on prejudice against female leaders to contextualize our findings. Data were collected through a survey using a convenience sampling method, targeting employees of trade union organizations in Sweden.

The objective of this thesis is to examine the capital structure of Swedish small and medium sized enterprises (SMEs). Accounting data from Swedish game developers, combined with the result from a survey, is used to examine their financial conditions and capital structure decisions. We find that non-debt tax shield, firm size, growth opportunities and age are, to various extents, the determinants of capital structure in the game industry, while effective tax rate and asset structure have marginal effects. Our study also implicates that most of the existing capital structure theories can explain SMEs leverage decisions to some extent; however, some adaptation is needed to fit these theories into the SME context. Additionally, we find the existence of a financial gap in the game industry which might need efforts from both demand side and supply side to eliminate..

The aim of this study was to find out how journalism students at two universities in Sweden, Gothenburg University and Linnaeus University in Kalmar, use the social networking service Twitter. We were primarily interested in whether the students are using Twitter as a journalistic tool, which includes gathering, production and distribution of material. The study focused on journalism students because they soon will enter the working life and therefore can provide an indication of whether Twitter is a part of the future of journalism. We have used theories of mass communication to describe the development in the area and explore how journalism has adapted to this change. The study was conducted in the form of a survey in which the students answered questions about how they use Twitter and what they think about the social networking service.

The smartphone market is growing rapidly, between Google Play and App Store more than 25 billion apps have been downloaded since 2008. Today many companies develop their own smartphone applications (apps) for their customers. We believe that many apps are developed without much consideration about the actual value it brings to the customer, and through them, value for the company. Instead they create applications with hope of keeping the company modern. Developing and implementing apps in a business is neither easy nor free and must therefore add value to the business in some way.

Sixbottles were choosen and they were all testet on 20 consumers each with a Likert-scale test.

Practice of mathematical proof increase the understanding of mathematics anddevelop creativity skills, problem solving, communication, logical thinking andreasoning which are all important tools not only within the subject of mathematicsbut also important tools for the society in which we are living. The aim of this projectwas to investigate whether it is accurate that proof and proving has a subordinate rolein mathematic education in the upper secondary school in Sweden. This was done byconstructing of a digital survey that was sent to approximately 100 practicingmathematics teachers in a normal size city located in the middle of Sweden. Theresults of the survey show that the teachers consider themselves comfortable withtheir own skills in teaching proof. Paradoxically, the results also show that there is alack of teaching of proof and proving in the upper secondary school, although the newcurriculum puts more focus on proof and proving..

Hunting ground graves were distinguished as a separate category during the 1930s.         There is however no clear definition of what a hunting ground grave is. They have been constructed over a large area over a long period of time (200 BC-1200 AD) and their morphology varies.This paper investigates how the archaeologists have discussed the hunting ground graves since they were distinguished as a separate category until today. It investigates what concepts that have been used to define and categorize the graves as a group. It also investigates if the choices of concepts are depending on a broader societal perspective.To find the answers to these questions two surveys have been done.

The construction industry has demands on energy use in permanent buildings. How much energy that is permitted to use during the time the building is produced has no requirements. The purpose with this study is to learn how far Skanska has come with the work of making the building site more energy efficient.A literature study has been performed in the beginning of the study to survey what energy efficient arrangements that can be applied and how they operate. Using site visits and interviews the situations on the building sites have been studied as well as the energy efficient measure that are in use.Skanska has come a long way with the work of energy efficient building sites and they keep improving. They have improved half of their cabins so they use 50 % less energy.

This essay has been made on behalf of the co-operative society Mäster Grön, which is selling ornamental plants to retailers in Sweden. The aim of this study has been to find out what added value Mäster Grön gets from their co-branding with the Swedish Seal of quality. The main topic of discussion was; how much value added does this co-branding give to Mäster Gröns pot plants? Are there differences from a customer point of view in value added between a garden center and a retail store? How much weight does the costumer put on the branding when buying a plant? Does the customer know what the values of Mäster Grön and Swedish Seal of quality mean? Two questions of lesser worth were asked to the consumers about what they thought about the protective plastic around the plant, and if they were interested in getting more information about the origin as well as the method of production of the plant. The study was divided into two parts, one in which customers were observed and one where the customers answered a survey.
