Flyktingpolitiska diskurser: en kritisk diskursanalys av två debatter
The central goal of this study was to compare statements of the minister of migration in power in 1994 with those of the minister of migration in 2006. The statements reflect two peaks of refugee immigration in connection to the war in former Yugoslavia and the present war in Iraq. The study analyses the statements in a critical discourse analysis framework. More specifically the aim was to find out if there were any discursive differences in these statements and how they might manifest themselves in society. The material was composed of 12 texts, 6 for each period originating from Swedish newspapers and from the ministers' public speeches.
Födoberikning av vitörade silkesapor (Callithrix jacchus) i djurpark : ? En studie om vitörade silkesapors beteende och kostintag, samt hur de genom födoberikning kan stimuleras till ett naturligt beteende i djurpark.
Det här arbetet syftar till att undersöka om och hur födoberikning kan stimulera vitörade silkesapor att utföra högre frekvenser av naturliga beteenden samt att se hur aktiva aporna är och om de frivilligt visar sig för publik på djurparken. Födoberikningen gick ut på att erbjuda aporna mat på ett mer naturligt sätt istället för att enbart ge dem maten i matskålar. Dessutom syftar arbetet till att erbjuda aporna en näringsmässigt korrekt sammansatt kost. Studien utfördes på två grupper av vitörade silkesapor på Parken Zoo i Eskilstuna under perioden juni till september år 2004. Undersökningen delades upp i tre perioder, under period 1 observerades aporna utan att någon födoberikning genomfördes.
UTVECKLING OCH KONTINUITET: En nyinstitutionell fallstudie av ett danskt folkbibliotek i förändring
Title: Development and continuity: A new institutional case study of a Danish public library in changeAbstract: The purpose of this master's thesis is to discuss and analyse the relationship between the traditional core values belonging to the institution of the public library, and the development work that takes place at the institution. The thesis also investigates the relationships that influence the development work.By investigating a library that is considered progressive in its development work, our purpose is also to unveil alternative values that compete with the traditional core values. By illustrating the perception among seven staff members and the director at Aarhus Public Libraries, we want to illuminate the terms for development among public libraries. In addition to our interviews, an activity plan is studied.We base our study on new institutional theory which focuses on norms and values in an organisation. This focus helps us to understand the development work from a comprehensive view.Our study shows that the development work at Aarhus Public Libraries is taking place in a complex environment that consists of several different actors and different interpretationsof the traditional core values of public libraries.

"Här handlar det ju om att man inte vet att man inte vet". En kvalitativ studie om synen bland professionella inom socialt arbete på begåvningshandikappade och föräldraskap
The purpose of this study was to examine what social workers include in the term "parenting ability". More specifically the purpose was to investigate how social workers view the parenting ability among parents with an intellectual disability. Furthermore the aim was to examine what difficulties social workers come across in their work with families where one of the parents are intellectually disabled. The study was based on six interviews with social workers that specifically work with children under the age of 18, and occasionally come across parents with this type of disability. The interviews were analysed using Donald Winnicott's terms "good-enough-parenting", "holding" and "the holding environment".
"Arbetslöshetssjukan": en kvalitativ studie av arbetsförmedlares upplevelse av arbetslösas mående
The purpose of this study was to examine how the personnel of the Employment Office in Malmoe interpret the emotional situation and health of unemployed individuals. We also wanted to examine if and how the personnel work with these aspects. In relation to this we found it very interesting how the personnel dealt with the responsibilities of power, hierarchy and how subordination afflicts the unemployed. Our main questions were: Are the previous studies results confirmed by the response the personnel of the Employment Office give about the difficult situation among unemployed individuals? Which factors do the personnel at the Employment Office consider the main causes of negative emotional situations among the unemployed? How do the personnel deal with the emotions of the unemployed? How does the important responsibilities of power affect the relationship between the personnel and the unemployed? Which effects/impacts from current political changes are the personnel able to see on the situation of the unemployed? We interviewed eight people working at the Employment Office in Malmoe.
Den nya smygreklamen : En kvalitativ studie av Avsändar-Finansierade Program och dess betydelse för tv-branschen
Syftet med studien är att belysa, problematisera och diskutera fenomenet Advertiser-Funded Programming eller Avsändar-Finansierade Program som det kallas för på svenska. Avsändar-Finansierade Program är en av de senaste trenderna när det kommer till att integrera organisationskommunikation med massmedia. Annonsörerna har tagit steget från att enbart exponera produkter och varumärken i reklampauser i och mellan program till att nu finnas med som en finansiell aktör i finansierings- och produktionsprocessen. Samtidigt som organisationers externa kommunikation integreras i underhållningsprogrammen minskar publikens möjlighet att värja sig från kommersiella budskap eftersom budskapet blir en del av det redaktionella innehållet. För att hämta åsikter och tankar från personer som direkt berörs av annonsörernas intåg i produktionsprocessen genomfördes kvalitativa intervjuer per telefon med personer som arbetar aktivt med AFP.
(H)elt om marsch!
The focus of this essay is on a political party that was founded in Sweden in 1904. Today, we known it as Moderata Samlingspartiet. Historically, this party has transitioned through multiple phases which have included a change of name and also a change of substance in the area of trade policy. The party that was cheering globalisation at the 2006 congress had its roots in protectionism and had been founded as a strict protectionist organisation. The question raised here is what has caused this dramatic change in the trade politic?In addressing this important question, I have used both organization and party strategy theories to identify the main underlying reasons.

När spelen blev farliga: konstruktionen av dataspel som ett socialt problem i svensk press 2000-2006
This essay focuses on the construction of so called "computer game addiction" or "computer game abuse" in the Swedish press during 2000-2006. During this period computer game addiction went from an obscure phenomenon to a legit reason for the involuntary commitment of a fourteen-year-old.The study's theory is based on several social constructionist ideas. Kitsuse and Spector's theories about constructing social problems as claims-making activities are used for understanding the actions of the individual and groups involved. Hewitt and Hall's article about quasi-theory is used to explain the construction of explainations for the new social phenomenon. Blumer's five-stage model is used for categorizing the construction of the new social problem.

Bilden av den kvinnliga stiftaren : en jämförande studie mellan 1100- och 1400-talets kvinnliga stiftarbilder på skånska kalkmålningar
In this study I compare the donor portraits on wallpaintings in Scanian churches from the 12th and the 15th century and relate them to medieval society.I find that women were equally capable of owning and donating land during the entire period. The image of the ideal woman changed during the 14th century from a married woman to the unreachable mistress of the chivalrous culture and the holy virgin. Women had a natural place beside their husbands in 12th century donor portraits, while single male donors are more frequent in the 15th century. While 12th century donors were supposed to show their position in society by offering plentiful donations directly to God, donors in the 14th century instead strived to present themselves as humble and pious. The individualisation of late medieval society meant that people had to depend on themselves to achieve salvation..
