Mötet med det svenska språket - flyktingar berättar om sina upplevelser
The purpose of this thesis is to study how swedishness is constructed and narrated in two Swedish documentary series that picture the Swedish participation in the international ISAF mission in Afghanistan. The main focus lies on how the Swedish soldier as such is portrayed, on which values, characteristics and qualities that they are said to embody and how these are linked to notions of swedishness, particularly the strong historical narrative, formed during the second half of the twentieth century, that defines Sweden as a peaceful, neutral and humanitarian state, with peaceful, enlightened and democratically minded citizens. Theoretically it draws on the concept of metanarrative to explain how ideas of shared national origin translates in to a broad organizing discourse, that defines, interprets and communicates notions of what it means to be a Swede and what is needed to make claims on swedishness. Another concept, that of national bodyscape, is also used to further define and explain how ideas of nationality are embodied and take the form of specific characteristics and personal qualities. The meaning-making in these two series makes use of the above mentioned definition of swedishness as defined by humanitarian concerns, democratic ideals and moral superiority to construct an image of the Swedish soldiers as on the one hand soft, humanitarians, who are needed in Afghanistan because of their especially strong sense of justice and moral, and, on the other, as tough soldiers, who are able to participate in every aspect of the war as fighters.
Osynliga nyhetsoffer eller som du och jag : Framställningen av personer med funktionsnedsättning i Rapport och TV4 Nyheterna
In this study we examine to what extent people with disability participate in television news and how they are represented. We chose to examine one broadcast per day of SVT Public Service news program Rapport and commercial channel TV4 Nyheterna (TV4 News) during one month using quantitative content analysis and qualitative discourse analysis.We found that people with disability are underrepresented in television news. In Rapport only 1,9 percent of the total broadcasting time contained people with disability and in TV4 Nyheterna 3 percent of the total broadcasting time contained people with disability. In the news people with disability were often represented as stereotypes, most commonly as victims. The focus was often on the medical aspect of the disability and on the problems that people with disability had.
Utveckling av processparametrar inom en hårdmetallindustri
This report analyzes and examines a hypothesis for finding a method to optimize thelength of the delubrication process time based on a total charge weight. The work hasfocused on the holding time for delubrication and the total charge weight.An important step in the manufacturing chain of cutting tools is when the greenbodies undergo the sintering process. Today, the delubrication step has the sameprocess time independent of the total charge weight. An implementation of a methodto adjust the delubrication process time would give more consistent quality of thecutting tool´s internal characteristics but also reduce the time course of the sinteringprocess. In the present project two methods for this goal were tested, thedevelopment of an algorithm and a weight interval subdivision with associateddelubrication process times.During delubrication a pressure increase is observed due to the decomposition of thePEG in the powder mixture.
Dagvattendammars reningseffekt : påverkande faktorer och metodik för statistisk modellering
Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.
Följdinvandring och medborgarskap : en statistisk analys
During the last years around 100 000 immigrants have arrived to Sweden, people with different reasons and different goals for settling down in Sweden. The reason for immigrating to Sweden that will be dealt with in this thesis is following immigration, i.e. when someone moves here because they have relatives living in the country.The reason why it is interesting to study following immigration is that it is an affecting factor for how many that will immigrate to Sweden the following years and may then be used to make a forecast, based on how many first time immigrants there are. To be able to investigate the following immigration analyses are made with time series, logistic regression and Poisson regression. An ARIMA-model has been used to estimate the number of following immigrants in the future.The other part of this thesis will inquire the matter how inclined immigrants are to become Swedish citizens, whether they even apply for citizenship and also how long time it takes from the time when they fulfil the conditions for Swedish citizenship until they apply.
Höghöjdsanpassning av BvS10 : Konceptstudie för optimering av överladdningssystem
This report relate a concept study that consider a number of different proposals to improve the overcharging system in BAE Systems Ha?gglunds tracked vehicle series BvS10, to maintain sealevel power at extreme altitude.At high altitude the power losses beacuase of the air density that decreases, which results in less fuel can be burned. The decreasing of air density also gives rise to fatigue failure of the turbocharger unless power is reduced.The proposals shall be as required by BAE Systems Ha?gglunds economically sustainable and defensible from a packing perspective. That means the selected solution must have a reasonable price tag and at the same time a minimal impact on adjacent components.The basis for this thesis is based on benchmarking of both the auto industry as the flight industry, to find inspiration and tips for improvement.Some of the concepts have after gathering facts and calculations been excluded while other solutions has been considered as workable and thus interesting for BAE Systems Ha?gglunds.Initially the current turbochargingsystem was analyzed in order to determine the starting point and thus be able to fix the current problems surrounding high altitude driving.
Konstruktionsforslag for kabelprovningsutrustning av serieresonanstyp
In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.
Bubblor och kapitalstruktur : Förändringar i kapitalstruktur i samband med bubbelsituationer.
Financial bubbles are characterized by a large increase in the economic growth on the market as a whole or in specific industries. The change gives rise to an increase in the capital needed to finance this growth. Companies typically have a choice between equity and debt capital to finance its business and the mix of these types of capital is often referred to as the company?s capital structure. There has been a lot of research done in the field of financial bubbles and ofcapital structure, as of yet no studies seem to address these two areas in combination.The aim of this study is to examine if financial bubbles affect a company?s capital structure and through this also examine if the supposed changes in capital structure can be generalized.The study comprise of two identical time-series which examines the changes in leverage and the choice of financing during the Swedish real estate bubble in the early nineties and the IT-crash at the end of the 2000th century.
Utveckling av I/O-modul för trafikskyltsystem
This thesis has been carried out in collaboration with LEDtec International AB. LEDtec focuses on innovative solutions in LED screens. Everything from large advertising signs to welcome signs in cities, to screens indicating speeds or warning of heavy traffic. The task was to was to help them develop a new version of the control board that is used in some of their products. The reason for this is that their old control board is obsolete and the components that are on it, is no longer manufactured or in need to be renewed.

Strävan efter det legitima polisväsendet : En jämförande studie mellan tre postkonfliktländer
Products and services have for a long time competed with their brands. For some time now, cities have begun to compete with each other to attract visitors and other stakeholders to come to their town. It is important that the citizens feel as they are a part of the message that the city sends out in its communication.Cities are today working actively with their brands, much like regular companies, in order to create the profile and image in order to be competitive against other cities and places. Cities and places are part of a dynamic process which includes both positive and negative events. These events might have an impact on the brands, and therefore it is a necessity to be able to react on these events to make the most of positive things and deal with the negative in a way that minimizes the effects on the brand.Citybranding as a research field is quite new.

Löneutvecklingens bestämningsfaktorer i Sverige
The purpose of this essay is to acquire variables that explain and may be used as a base for wage estimation in the private sector in Sweden. The factors that are assumed to have an impact on wage estimation are based on earlier Swedish and international studies. Business survey data, which is based upon monthly questions to firms in various sectors of the Swedish economy posed by the Swedish National Institute of Economic Research, will be analyzed to find out weather they have an impact on Swedish wage settings or not. Tests including business survey data are yet rarely frequent, why this essay will be some kind of a pioneer within the area. To estimate significant factors that influence wage setting in Sweden, three different wage equations have been modeled and tested with a regression model.
