Syfte: Syftet med denna litteraturstudie var att beskriva hur det är att leva med Polycystiskt ovariesyndrom (PCOS). Metod: Deskriptiv litteraturstudie. Data inhämtades från databaserna Pubmed och Cinahl. Resultatet baserades på 14 evidensbaserade artiklar. Resultat: Kvinnor med Polycystiskt ovariesyndrom hade större risk att utveckla ångest och depression jämfört med normalpopulationen, orsaken till detta är inte klarlagd forskarnas åsikter går isär.

The purpose of this study was to examine how local producers in the food and confectionery segment in Västernorrland, Sweden, working to communicate that the product is locally produced through its packaging design. We have chosen to look at how they work with the right packaging design because it is such an important part of the product marketing. A further aim was to examine how consumers perceive the packaging design of the locally produced products and how they consider that the packaging design communicates the product as locally produced. We have also analyzed the graphical elements contained in the locally produced product packaging through a semiotic analysis.The theoretical framework is based on theories in brand communication and Visual Communication, specializing in packaging design?s visual elements.The method used in this study is a qualitative method.

The purpose of this master?s thesis is to examine how pupils with Swedish as a second language and school librarians perceive the concept of pleasure of reading and the feeling of being a part of society. Our research is based on qualitative interviews with eight students in grades 6-9 and from two different schools. We have also interviewed two school librarians in these two libraries. As a method of analysis, we used phenomenography because it is the informants' perceptions of the phenomenon of pleasure of reading that we investigate.

In this thesis I will discuss how US respectively EU general international security policies are formed with the scientific theories Rational Choice and Cognitive theory in mind. I?ll discuss how come US tends to go towards a more sanction orientated strategy while European Union seems to prefer a dialog and diplomatic problem solving strategy. I?ll exemplify respective security strategy through the qualitative cases study of Iran and analyse why they have taken different cores of action while trying to solve the problem with Iran's alleged nuclear weapon.

A politician on the peak of his career suddenly sees himself in the middle of not one or two, but five different crisis, that demand a fitting response and a well planned crisis management strategy. While focusing on ethos and its development, the following paper analyses the communicative strategies used by Germany's ex-minister of defense, Karl-Theodor zu Guttenberg. Within his one and a half year tenure he had to handle continuing accusations against policy and character. Guttenberg, who in many eyes was seen as Germany's most popular politician and whose ethos, therefore, prior to the first crisis could be described as strong, is loosing his trustworthiness among the military and other politicians the longer each crisis continues.The purpose of this study is to identify the communicative pattern of Mr. Guttenberg, which in the end lead to his resignation, while his popularity continues to be strong.

This thesis work has introduced process orientation at the printing company Color Print Sweden AB. The outcome ofthis work is a survey of the work flow at the prepress department. To visualise the production process at the companya comprehensive mapping of the main process, order-to-delivery, has been made. The work has detected a couple ofcritical elements in the existing process. These elements are the following: initial check of material delivered to the prepressdepartment as well as the control made of the plotter print-out, digital test print and plate.

In this essay I have studied Aftonbladets portrayal of the Swedish businessman Jan Stenbeck and if the reporting changes before and after his death, and if so, in which ways. With help from a qualitative syntax analysis and a content analysis I studied my material about Stenbeck during the time period 2000-09-19 to 2004-09-19. In my quantitative analysis I studied 140 articles and in my syntax analysis I studied ten articles, five before and five after Stenbecks death. The theoretical perspectives that I applied in my study is Sigurd Allerns theory about tabloid papers novelty criteria and Adam Shehatas theory about Framing. Allerns theory describes what criteria the tabloid papers have on news and Shehatas theory about framing describes the political forces behind the news who wants to set their own agenda.

We have 3G on the doorstep but nothing seems to attract ordinary people to this technology. To attract the mass market the telecom industry must show something beyond high bit rates. They must show how ordinary people can take advantage of this new technology. This is done by showing the possibilities of the new technology and by demonstrating applications that it will handle. The telecom industry must convince the telecom operators to invest in this technology and the only thing that matters to them is how much revenue they can make by adopting the upcoming technology.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

This work is about the expanded conception of text and takes off in the use of this expression in the high school curriculum. The work begins with a theory chapter, where a few different definitions of text are the basis for reasoning about factors which can have contributed to an expansion of the conception. Hereby other important expressions, related to the expanded conception of text, as hypertext, multimedia and intermediality, are brought up. Further, is examined empirically how the expanded conception of text is interpreted, rhetorically and practically, by a few teachers in the High School. Finally, covered scientist?s theories are discussed and compared with the concluded empiric data.The study shows however, that the expanded conception of text in the curriculum has not become a conception for the teachers who were interviewed.

Det talas idag mycket om Sveriges satsningar på en skola för alla. Samtidigt mår många elever dåligt. Det är något som inte stämmer. Syftet med denna studie är att undersöka hur elevernas självbild påverkas av specialpedagogiskt stöd. Avsikten är att beskriva självbild, självkänsla och självförtroende, ur den enskilde elevens synvinkel.

The problem presented in this report is that of finding a method to calculate the lift force from a single-element airfoil of arbitrary shape. A number of restrictions are used in order to simplify calculations while retaining reasonable accuracy. The problem is solved for the two-dimensional case only and no finite-wing effects are taken into account. Furthermore, inviscid and incompressible flow is assumed. The method used to solve the problem is the vortex panel method, with vortex singularities distributed over simplified airfoil geometry.

Since the 1950s new laws on higher education have led to a ?mass education phenomenon? in Sweden. This has led to a surplus of people with a university degree measured against available positions on the labor market. As a result of that development it must be assumed that in this over qualified society it is not anymore the degree but additional factors which are decisive for getting a job. In this respect the importance of the class background for getting a jobb that is equal to once level of education shall beexamined.The research was carried out by means of a Quantitative Analysis based on data from anational database called Undersökningar av Levnadsförhållanden (Survey of LivingConditions).
