"om du vill ha en riktig vän - köp en hund" : en granskning av Aftonbladets framställning av Jan Stenbeck före och efter hans död
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.
Analys av Nedbrytningsprodukter av Polymerer för Bitumenändamål
This project was aimed to study the degradation of polystyrene-butadiene-styrene block copolymer (SBS). SBS is used to modify bitumen, the binder in asphalt. From earlier studies it is known that SBS degrades in bitumen, but the degradation products have not been identified. To be able to determine the long term effects of SBS in the environment, degradation products need to be identified. Polystyrene forms rigid blocks with polybutadiene as a rubbery matrix between the ridgid blocks.
End-to-End Application Billing in 3G
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.
Analys av tanniner : från granbarksextrakt
The objective for this master?s thesis was to test and evaluate two methods for determining the content of tannin in a pinebarkextract. The methods used at Södra for this previously have not been specific enough, only the amount of polyphenolics have been measured. One of these methods is a test based on the Stiasny test and it determines the extracts ability to form a gel with formaldehyde. When this test was carried out it showed that the extract did not contain much tannin.
Green feed in the marine fish farming : how to communicate water benchmarks to stakeholders
Global catch fishery is said to been oppressed to its limit (Boyd & Schmittou, 1999), further implying aquaculture might be the only solution to the world demand for fishery products. The applied term aquaculture in this paper refers to the one used by NOAA (2008); breeding, rearing, and harvesting of plants and animals in all kind of water environments, including but not limited to ponds, rivers, lakes, and the ocean. According to Shamshak & Anderson (2008, p. 74) aquaculture has over the past 20 years been the fastest growing food sector with an average annual growth rate of 8.7%. It further represents approximately 37 % (Shamshak & Anderson, 2008, p.
Sedimentation av lera och fosfor i en anlagd våtmark
The amount of various phosphorus (P) fractions in the sediment and the relationship between the amount of P and sediment particle size were investigated in a constructed wetland southwest of Linköping. Furthermore, the possible correlation between clay content in the sediment and distance from the inlet was investigated. Sediment samples were collected along three transects from the inlet to the outlet, with six samples in each transect. In order to measure the soluble P, an NH4Cl extraction was done. This was also analysed for total soluble P after oxidation with peroxodisulphate.
Väneramplitud ? Lönsamhet? : Kvalitativ studie av åtgärder, genomförda för att reducera risker och kostnadspåföljder av en förändrad vattenregim
Tappningsstrategin för Vänern ändrades i ett beslut från Länsstyrelsen i Västra Götalands län och Vattenfall AB, på uppdrag av regeringen år 2008. Detta gjordes för att minska risken för översvämningar i Vänern. Åtgärden var föreslagen av Klimat- och sårbarhetsutredningen, som försökt utreda konsekvenser av klimatförändringar för Vänern i ett framtida förändrat klimat. I utredningen används en metod för att mäta kostnader. Metoden är en kostnads-nytto-analys (Cost-Benefit-Analysis; CBA) som användes för att utvärdera bland annat Vänern med omnejd. Enligt denna uppsats saknas det värdering för naturmiljö och sociala faktorer i denna utredning.
Omvärldsbevakning och folkbibliotek en innehållsanalys av facktidskrifter inom biblioteksfältet
The research of this Masters thesis examines if during a specific period of time, Environmental scanning connected to Swedish public libraries is discussed in journals that are directly connected to the field of Swedish libraries. The method employed was content analysis of articles, news items and ads with the intention of finding out the extent of Environmental scanning and who carries it out and how and what is scanned. The research covers the period from 2004-01-01 to 2004-08-31. During the research period 1387 articles, news items and ads were analyzed. The study focuses on 81 selected published units that directly include references or discussion about Environmental scanning.
Krig, mäktiga kungar samt en och annan "påsmetad" notis om kvinnor : En genusstudie av läromedel i historia
This study revolves around calculating the extent of appearance of both anonymously and named men and women as well as determining whether or not Yvonne Hirdman?s gender theory is applicable on two versions of a Swedish educational history textbook called Epos: historia: för gymnasieskolans kurs A (2008) and Epos [historia] 1b (2012), published for two different curriculum. Our qualitative investigation of two parts of the book?s content proves that the two principles of gender system are present in both books, although to a lesser extent in the latter version. Calculating the material, results have shown that anonymous men and women are almost equally presented in Epos 2012, which is not the case in the 2008 version.

What is the content in information seeking education?? What aims are focused in information seeking education?? What methods are used in information seeking education? The methods being used are empirical studies and studies of literature, within the subject area. The study is inspired by phenomenographical learning theories.
From elevator pitch to organizational vision - How does the personal idea become an outspoken organizational vision?
The purpose of this dissertation is to create an understanding of how a personal idea in the mind of an entrepreneur becomes an outspoken vision in one biotech company. More specifically, for what purpose the vision is used at different stages, how it is communicated, its content and what impact previous visions have on future vision work and in order to reach a deeper understanding of how vision develops over time and how it is used we have employed a qualitative approach based on a case study. The theoretical framework starts with the concept of vision and related concepts. Furthermore, the entrepreneur?s and manager?s usage of vision is examined.
Svensk Dagspress - Dressed for Success? : En kvalitativ undersökning om dagstidningens framtida utveckling i sökandet efter en fungerande affärsmodell
The digitalization of the media industry has involved great changes for the Swedish daily press. Instead of subscribing on a daily newspaper, more people tend to read newspaper's free edition online. The recent recession has contributed to strike hard against the newspaper's economy. This is the problem our research is based upon. How will the newspaper develop and which measures have to be done to get a well functioning business model that is suited for future conditions?We have made qualitative interviews with Swedish newspapers: Göteborgs-Posten, Norrköpingstidningen, Sydsvenskan and with the danish newspaper Politiken.
An image-based method for identification of new inhibitors of Signal Transducer Activator of Transcription 1
Background: Chemotherapy and radiation resistance are major causes of failure in cancer treatment. The response to treatment in cancer cells depends on several mechanisms and pathways such as Janus kinases-signal transducers and activators of transcription JAK/STAT pathway. STAT1 was the first described transcription factor in the STAT family. STAT1 is activated by stimulation of signaling proteins such as type II interferon (IFN- ?) and the activated STAT1 translocates from cytoplasm to nucleus.
Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Produktutveckling av koncept för isbanesystem
Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.
