Sikta mot Stjärnorna: En komparativ studie över bloggares och kändisars effekter på konsumentbeteenden och konsumentattityder
During the second part of the 20th Century celebrities became more commonly used for commercial purposes as they could enhance purchase intentions, word-of-mouth- intentions and change attitudes towards brands and products. Over the last few years blogs and bloggers have become more and more used for product placing and the bloggers? power over consumers? behaviour has grown rapidly. The aim of this study is to compare a celebrity?s and a blogger?s impact on consumer behaviour and try to understand the underlying reasons why they do have such power over their audiences.
Metodik för utmattningsberäkning av svets i vibrationsmiljö
In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.

Regional utvecklingsplanering och grönstruktur : en studie av de gröna kilarna i Stockholms län
The aim of the thesis is to analyze the role of regional development planning concerning a regional perspective of green structure and to reflect on its future role. The target group of the study is foremost practitioners but also students of regional planning and development.
Three questions are examined. 1) What view concerning green structure has the regional planning body of Stockholm County Council (RTK) communicated through the years? 2) Has this view contributed to generating a common understanding concerning green structure among the actors in the county? 3) Has this common understanding been referred to by actors in discussions concerning how this green structure should develop?
The empirical material consists of documents from rtk, the County Administrative Board, the municipalities of the county, a network of ngo:s, as well as interviews with representatives from the above mentioned organizations.
Ungdom och inflytande en diskussion om hur ungdomar upplever sina möjligheter till makt och inflytande i samhället
The purpose of this master's thesis is to discuss how young people view their possibilities of exercising power and influence in Swedish society and politics. To accomplish this we have used several different sorts of relevant material. As an introduction, we review the development of the Swedish research concerning youths, with focus on the development in the last two decades of the twentieth century. We continue with a study of important Swedish youth-political documents, especially of the Government Bill På ungdomars villkor: Ungdomspolitik för demokrati, rättvisa och framtidstro On the terms of the youth: Youth-policy promoting democracy, justice and hopes for the future. The Bill is the foundation of a new youth-policy in Sweden.
Inte homofob, men... : Socialarbetares attityder till homo- och bisexuella personer
The purpose of this study is to identify and make attitudes among social workers towards homosexual and bisexual people visible, examine how these attitudes relate to their actions in their professional role and how these attitudes and actions can be understood by theories of heteronormativity and power. The study is a cross-sectional quantitative survey in the form of a questionnaire completed by social workers. The result shows that there are two groups among the social workers. One larger group that reproduces a norm of acceptance toward homosexual and bisexual people and one smaller that reproduces a heterosexual norm. This reproduction of heteronormativity increases the risk for homosexual and bisexual people to be made invisible and treated more negatively in contact with social workers, which in turn can lead to worse health among the clients..
Habiliteringspersonalens mångfacetterade yrkesroll - En studie hur personal arbetar med LSS intentioner inom integrerat boende
This essay is about the staff in integrated homes very complex profession and this is illustrated through twelve interviews in five integrated homes for disabled people. The profession changed when the institution closed and especially when the Law of Support and Service (LSS) was introduced in 1994.The purpose of this survey is to study how staff works with LSS intentions in integrated homes for disabled people and to increase the awareness about the structure of power and how this affects the daily life for those who live there.The main objective in this survey is to find out which the differences that lie between LSS intentions and the work that take place in integrated homes for disabled people. This survey tries to illustrate when and why these differences occur. This survey has a multidisciplinary perspective, where three models of disability and theories from Foucault, Sibley and Wendell have been included. The result shows that the staffs work is difficult, full of responsibility and has many facets.
Förändringar av marknadsdesign och deras påverkan på balanshållningen i det svenska kraftsystemet : En kartläggning och analys av de balansansvarigas arbetsgång
A future expansion of wind power in the Nordic power system makes the balancing for the transmission system operator Svenska Kraftnät (SvK) more complicated. Up to the hour of delivery the balance responsible parties? (BRP) makes prognoses and plans, for consumption and production, to help maintain the balance in the electrical grid. How well this is accomplished is affected by the setup of the market design. Therefore SvK has proposed the following possible changes in market design: Increase the imbalance costsIntensify the regulation of imbalancesIncrease the temporal resolution on the different marketsPresent the prices for balancing power in real-timeModify the balancing market to simplify auction of consumption bidsA mapping over the BRPs? processes within planning and trading on the day-ahead, intra-day, and the balancing market has been performed in this thesis.
Numerisk simulering av jordtryck mot rörbro ? Med tillämpning av programmet PLAXIS
This thesis deals with numerical simulation of earth pressure against tubular bridges in the software Plaxis. Plaxis is a FEM (Finite Element Method) software based on numerical calculations for which approximate solutions are developed through an iterative process. The program is specifically designed for soil and rock mechanical tests, such as voltage and deformation calculations in soil.The Royal Institute of Technology conducted in 2005, field tests on tubular bridges of corrugated steel, which was part of Ersa Bayoglu Fleners PhD (Bayoglu Flener, 2009). She studied how two different tubular bridges deformed during installation and filling. Tests and measurements were made during filling.
?Boobs or gtfo? : En kritisk diskursanalys av bloggar i den svenska gamingdiskursen ur ett genusperspektiv
Research in the field of gaming and the gaming culture shows that the culture is characterized by sexism and hypermasculinity, however a majority of this research is conducted in an Anglo-Saxon context. Therefore the aim of this study was to elucidate the Swedish gaming discourse in relation to gender, gendered norms and stereotypes. We also sought to examine the relationship between the editorial content and the blog comments. The study was based on a critical discourse analysis with a gender perspective, applied to five Swedish gaming blogs. By implementing power theory and encoding/decoding theory, we have concluded that there is a discursive struggle, where one part of the gaming culture is characterized by male dominance, while the other part of the discourse is showing signs of resistance to this hypermasculinity.
Planering av produktionsflöden. Vad kan påverkas i projekteringsfasen?
Göteborg Energi AB är ett bolag med höga ambitioner att säkerställa ett stabilt distributionsnät för sina kunder. Med ett säkerställande följer åtgärder i form av beräkningar för komponenter som transformatorer av olika märkeffekt, hög- och lågspänningssäkringar och andra kritiska skyddsanordningar som t.ex. reläskydd. Vid ett flertal tillfällen under de senaste åren har det uppmärksammats en problematik där ett fel i lågspänningsnätet har löst ut anslutande transformator. Felet har grundat sig en svag selektivitet mellan transformatorsäkring och lågspänningssäkring.

Bonniers och AB Mariebergs ställning på mediemarknaden en analys av tre skilda debatter åren 1995-1998
International media groups and the freedom of speech are two issues that have been questioned during the last years when large media groups control a large amount of public-oriented information. The masters thesis at hand considers three debates that illuminate Bonniers and AB Mariebergs hereinafter referred to as the Bonnier Media Group positions on the media market. The objective of such a study is to establish in the face of the theory on hegemonia, for example from which factors the media actors deduce their argumentation when discussing the above-mentioned topic and the meaning of such a discussion in our time. The thesis also discusses whether freedom of speech and free opinion are affected by the increasing power of the Bonnier Media Group and if they, as a result, have diminished their own cultural and liberal assets, features that are firmly associated with the company. I conclude that various features have come to change the media market during the last years.
Rening av metallhaltigt avloppsvatten : En teknisk/ekonomisk utvärdering av reningsmetoder för metallhaltigt avloppsvatten
This Master?s Thesis aims to investigate and assess the methods used to decrease the discharge ofmetals, primarily copper, from the water purification plant at Assa Industries plating factory inEskilstuna.Literature studies of the purification methods precipitation, ion exchange, evaporation, reverseosmosis and electrolysis has been done to appraise the adequacy of the technique. Thesetechniques are commonly used for purification of industrial waste water.Assa has four plating lines: the Trumline, the big Zinkline, the new Zinkline and the Decorativeline. The new Zinkline is the most modern of the four lines and purification is done byrecirculation over an ion exchange unit. The demand for fresh water is thereby heavily reduced.The Trumline, the big Zinkline and the Decorative line all use older techniques.
