Beteende inför lek hos odlad respektive vild lax (Salmo salar L.) i Klarälven
In many regulated rivers, authorities have stocked hatchery salmon to compensate for loss of wild populations. However, hatchery fish have not always behaved as wild fish do, and stocking them has not always fully compensated for the loss of wild fish. The purpose of this study was to compare swimming behaviour in the river before spawning, the choice of spawning areas and body size between wild and hatchery-reared salmon in the river Klarälven. Salmon behaviour in the river before spawning was analyzed using radio telemetry. The salmon were caught at Forshaga power plant, radio-tagged and returned to Klarälven at Ekshärad, 107 km from the river?s mouth.
Debatten kring Patriot Act. American Library Association's och den amerikanska regeringens förhållningssätt till anti-terrorismlagen The USA Patriot Act of 2001
This paper addresses the need to review the modern presentation of textile archaeology in museums. It is time to look at textiles in archaeology with new eyes. The reality behind archaeological textilestudy is holistic, embracing many different aspects of society. The presentation of textiles has in my opinion become old-fashioned. I will show in my paper that Jonathan Adams? `seven constraints´ model, developed for research on ancient ships, can also be applied to textile research.
Being the media : decentraliseringen av nyhetsproduktionen och dess effekter på tidningsjournalisters informationsbeteende
The Internet provides the common user with a variety of both traditional and non-traditional news sources, and a vast range of possibilities to contribute to the flow of information. By their participation in the production of information ordinary citizens can sometimes function as non-traditional news sources them selves and reach a potentially unlimited audience. The interactive nature of the Internet blurs the line between producers and consumers, and challenges traditional definitions of what counts as "news" as well as who qualifies as a "journalist". The main purpose of this thesis is to examine the potential consequences of this decentralization regarding the information behaviour of newspaper journalists and their perception of their professional role. The study consists of qualitative interviews with six journalists, employed by four of the leading Swedish newspapers, and a review of earlier research in the field.

Platsrelaterat själv och autobiografiska minnnen hos svenskar boende i Schweiz
The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.
Kommasköldlusen Lepidosaphes ulmi (Linnaeus) i svensk äppelodling : livscykel och naturliga fiender
Lepidosaphes ulmi ? kommasköldlusen har dykt upp som skadegörare i svenska äppelodlingar de senaste åren. Svenska äppelodlare har efterfrågat mer information kring kommasköldlusen och dess naturliga fiender, och därför gjordes denna litteraturstudie. Kommasköldlusen är en
pansarsköldlus med ett hårt skyddande skal. Även äggen läggs under skalet och de är därför svåra att bekämpa.
Att leva med bipolär sjukdom : en intervjustudie
Bipolär sjukdom (BS) är en kronisk sjukdom med återkommande perioder av mani och depression. Den bryter oftast fram i tonåren men i många fall diagnostiseras den inte förrän patienten är runt 30 år. Behandling för BS är livslång medicinering med stämningsstabiliserande läkemedel, i första hand litium, kombinerat med anti-depressiva läkemedel och anti-psykotiska läkemedel. Läkemedelsbehandling kombineras med psykoedukativ behandling eller kognitivbeteende terapi (KBT). En intensivbehandling följer efter det att diagnosen är ställd och det tar ofta upp till 2 år för patienten att hitta en balans i livet.Syftet med denna studie är att få en uppfattning om hur det är att leva med bipolär sjukdom.
Produktplacering : ett sätt att kommunicera varumärkesidentitet?
Background: The consumers of today have the possibility to choose from a wide range of products and services. Consequently, the ability to differentiate the products is essential for the brand owners. If a brand owner does not manage to differentiate its product, it can be difficult to make the consumers realise the benefits of the product and convince them to buy it. One way to differentiate the product is to create a distinguished brand identity. However, it is not enough to create a strong brand identity, the brand owner must also be capable of communicating the brand identity successfully.
Emotionellt och psykosocialt välbefinnande hos barn med läpp-käk-gomspalt och barn med språkstörning. : Ett föräldraperspektiv.
Children with cleft lip and palate (CLP) and children with specific language impairment (SLI) may be affected emotionally and psychosocially by their disorders. Thus, it is important to investigate the psychosocial risk factors that these children are exposed to. The aim of this study was to examine how parents assess the emotional and psychosocial well-being of children with CLP and children with SLI, and if the two parental groups differ in their assessments using the standardized instrument Child Behaviour Checklist (CBCL). Participants in the study were the parents of ten children with unilateral and bilateral CLP between ages 6;7-9;0 (mean age 7;5) and the parents of 13 children between ages 6;4-8;8 (mean age 7;3) who are attending preschools and schools for children with SLI. These parents were asked to complete the questionnaires CBCL and Child Health Questionnaire (CHQ). The children with CLP had lower scores than the children with SLI in all domains of the CBCL, indicating that these children with CLP had better emotional and psychosocial well-being.

Rena händer räddar liv - Faktorer som påverkar följsamheten till handhygien - En tillämpning av the Theory of Planned Behavior
Vårdrelaterade infektioner är en av de vanligaste förekommande komplikationerna inom svensk sjukvård. Den drastiska ökningen av multiresistenta bakterier ökar sannolikheten för att insjukna i en multiresistent vårdrelaterad infektion och aktualiserar därmed problemet med den bristande följsamheten till handhygien. För att lyckas med att minska vårdrelaterade infektioner krävs en optimal följsamhet till handhygien, då handhygien anses vara det i särklass effektivaste sättet att förhindra smittspridning. Forskning pekar dock i motsatt riktning och visar en genomsnittlig följsamhet på 40 procent. En litteraturstudie utfördes med syfte att utifrån the Theory of Planned Behaviour belysa de faktorer som påverkar vårdpersonalens följsamhet till handhygien.
A comparison of group housing and individual housing for dairy bulls kept for breeding
This study was conducted at VikingGenetics' bull breeding station in Falkenberg, Sweden. The bulls waiting for the results of their progeny testing at this station are either kept in group housing or individual housing. Since both of these housing systems have advantages and disadvantages, it was in the interest of VikingGenetics to know which of these housing systems is the best. The aim of this study was to investigate the welfare of the bulls in these two housing systems through behavioural observations and the use of activity monitors. In the preparations for the study 16 bulls, 8 in each housing system, were chosen.
Ny världsordning, nya utmaningar? En teorianvändande studie om förhållandet mellan USA och Europa sedan Kalla krigets slut
In this thesis I discuss and analyse the relationship between USA and Europe since the end of the Cold War. Many authors claimed that the Soviet threat was the glue that kept the continents together. Now that threat is gone and new challenges have risen. In what way has this relationship been influenced by the new challenges this new era stands for? By doing a case study and by using two quite different theorists, John Mearsheimer an offensive realist and Joseph Nye who is a liberal institutionalist, I?ll try to show how for example September 11, anti-amerikanism and NATO can be explained and understood.
