Syfte: Huvudsyftet med denna uppsats är att undersöka betydelsen av finansiella rapporter genom att studera aktiekursens reaktion på Stockholmsbörsen för tidpunkten när företags finansiella rapporter blir offentliga. Detta bryts ned i två delsyften; Skapar årsrapporter synbara reaktioner på svenska aktiemarknaden OMX vid tidpunkten för offentlighetsdatumet? samt följer reaktionerna på svenska aktiemarknaden årsrapporternas status? Metod: Undersökningen är uppdelad i två delar. Den första utgörs av en nyckeltalsanalys, på 81 finansiella rapporter mellan åren 1991-2009, för att fastställa rapporternas status och den senare är en eventstudie som behandlar aktieutvecklingen vid offentlighetsdatumet för rapporterna. Undersökningen har en kvantitativ ansats där empirin består av sekundärdata i form av årsredovisningar, delårsrapporter och börskursindex.Teori: Rapporten bygger på hypotesen om effektiva marknader, signalteorin samt teorin om insiderinformation.Empiri: Utav 81 undersökta rapporter var 32 stycken starka, 27 stycken svaga, och 22 stycken neutrala.  Alla rapporters eventfönster för offentliggörandet gav antingen ett positivt eller negativt AAR.

In Sweden we have the highest rate of nontraditional students among Europe. Coincidently, we also have the highest rates of drop outs among OECD. In this particular field, drop out from higher education, there is a need fore more qualitative studies that can support the "statistics". Studies about experiences of drop outs are significant for society, university and individual. The aim of this study is to describe and understand how nontraditional student experiences drop out from higher education.

6 Sammanfattning och diskussionVi har i vår studie sökt behandla hur bostadslösa skapar status. I vår analys fokuserade vi på tre centrala statusbegrepp samt ett fjärde tema, vilket vi använde för att ytterligare belysa hur bostadslösa skapar status. Våra statusbegrepp var statusförhandling, statuskrock och statusbalans. Vi tycker att de har hjälpt oss i vårt syfte genom att belysa vad vi anser ha varit viktiga tendenser i våra intervjupersoners berättelser. Vi vill på ett idealtypiskt vis tydliggöra vilken relation vi menar att våra statusbegrepp har till varandra.

The population over 65 years of age is increasing and health in elderly has been a subject of research for decades but voice function and vocal health has not been prioritized. The purpose of this study is to obtain reference value for the Swedish version of Voice Handicap Index (RHI) and the Throat Scale among people over 65 years of age and assess voice function and vocal health for this age group. The questions were as followed:1) What is the reference value of RHI for people over 65 years of age? 2) What is the reference value of the Throat Scale for people over 65 years of age? 3) Is there a correlation between a self-rated VA-scale on the perceived degree of voice problems, and the self-rated RHI-/Throat Scale result? 4) Does age, gender or previous profession matter for the self-perceived voice?In total 100 individuals participated in the study, 50 women and 50 men, between 65 and 92 years old. The reference value of RHI for people over 65 years of age was 13,4 points and the reference value for the Throat Scale was 7,7 points.

The concept of the photographic truth has had a special status for almost 200 years. Yet with the emerge of digital technology and especially digital photography there has been a loss of the particular connection photography has had in reference to reality. The aim of this study is to see in what ways digitalization has affected the credibility of photography from the perspective of professionals in the field of photography. The digital technology that has enabled the large-scale manipulation of photographies is not, however, the main reason for the decreased credibility of photography. The ongoing discussion about the available possibilities concerning digital imagery and manipulation has had a far more powerful effect on the concept of the photographic truth.

The aim of the study was to explore the psychological well-being of a group of adolescents in relation to how they regarded achieving in school, in a gender perspective. Twenty semi-structured interviews were conducted with students aged 17-19 at a high-achieving school in a big city in Sweden. The interviews were analyzed thematically and the results showed that the adolescents acted differently as well as regarded achieving in school differently depending on gender. The young women were driven by ambition, they were high-achieving and planning for the future. The young men cared less about achieving and thought more about the present.

The effect of the salary system and age on the internal and external motivationThe purpose of the study was to examine how a fixed salary with commission and only a fixed salary, and age affect the internal and external work motivation of sellers. This was studied by a questionnaire and participants were sellers in the call center industry in Sweden. In total there were 112 sellers from nine different companies that responded to the survey. The respondents were divided into groups based on pay systems and age. The measuring instrument used was the Work Extrinsic and Intrinsic Motivation Scale which classifies the motivation of internal and external based on six subscales.

In the government's bill on infrastructure for 2010-2021, the government presents that road investments should be prioritized before investments in the railway. The grants for operation and maintenance of the railways are much higher then in the last government's bill. Furthermore the current founding of investment in railways is higher then for road investment which is in opposite of the bill on infrastructure's directives. Therefore the purpose with my thesis is to find which factors that can explain how come the government has chosen to take these actions. As a model to help me achieve my purpose I have been using a modified version of the DBO-theory, where the basic factors to explain an action is Desire, Belief and Opportunities.

Malignt melanom är en av de tio vanligaste cancerformerna. Insjuknandet har ökat på grund av ändrade sol- och resvanor. Utvecklingen beror främst på UV-strålningen från solen samt ökad användning av solarier. Idag är det främst de yngre kvinnorna som insjuknar. Det gäller att diagnostisera malignt melanom i ett tidigt stadie, då det ger en bättre förutsättning för överlevnaden.

I kursplanen för ämnet svenska finns det relativt nya vidgade textbegreppet, vilket innebär att text inte längre innefattas av tryckt text utan även kan vara bild, film, teater etcetera. Denna studie tar sin utgångspunkt i film som text. Syftet med undersökningen är att studera huruvida film som text kan likställas med den litterära texten i svenskundervisningen eller om filmmediet fortfarande, som forskningen benämner det, anses vara av låg status. I forskningsbakgrunden problematiseras filmens roll i svenskundervisningen och förslag på ytterligare bearbetningsmöjligheter angående film som text ges. Undersökningen grundar sig på intervjuer med tre gymnasielärare samt enkätundersökningar med respektive lärares elever, vilka läser kursen Svenska B.

Milk yield levels in dairy cows are influenced by many factors such as nutrition, breed, health status, management and environment. This study was conducted among small scale farmers in Zambia, where the climate can be dry for up to six months per year and cause a lack of green pasture for livestock and on-farm produced feed. The purpose of this study was to identify management factors that can influence milk yield at small scale dairy farms in Zambia, and present advice that could improve productivity, without the need of expensive investments. The study included semi-structured questionnaires presented to the farmers (n=29) including questions about cattle management and milk production. Testing of somatic cell count (SCC) with DCC (DeLaval Cell Counter) from herd milk samples (n=56) and observation of housing and animal body condition on-farm was also made.

Abstract  The importance of the co-occurrence of callous-unemotional traits and impulsivity concerning aggressive acts was examined by a survey. The participants consisted of 1478 Swedish youth. Three groups with extreme scores on callous-unemotional traits and impulsivity was identified.  The group scored high on both was more prone to show higher levels of aggressive and conduct problems behavior compare to the other groups. The aggressive and conduct problem behavior was shown at higher level in all examine variables. This study highlight that impulsivity can identify extreme aggressive individuals, without taking HIA (Hyperactivity, Impulsivity and Attention) problem as a entirety, to account, if shown with callous-unemotional traits. Keywords: Callous-unemotional traits, impulsivity, aggressive, conduct problem, youth, co-occurrence..

The two swedish unions, Akademikerförbundet SSR and Kommunal, have a majority of female participations who mainly work in the public services. The difference between the unions is that one of them only represents members with academic educations and the other has members with lower educations. The aim of this study was to compare the two unions according to the terms exit, voice and loyalty, but also participation and influence. There were 142 participants in this study and 8 participants were interviewed in a pre-study. The result of the study shows that voice is a strong predictor to wellbeing in work life.

Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.5 and 35°C for different suspended solid concentrations(8%, 10% and 12%) of pretreated birch slurry which contained 16 % total suspended solids.Two different hexose fermenting yeast strain (Ethanol Red) and pentose fermenting yeaststrain were used.Quantifying the concentration of chemical components and metabolites in the fermentationmedium demonstrated that glucose and xylose are the major fermentable sugars in the slurry.The higher load of slurry (12%) represents a higher content of carbohydrates and potentiallyhigher end concentration of ethanol. Moreover, more lactic acid is produced with the lowerload of slurry (8 % or 10 %), presumably due to a result of a less inhibitory environment forbacterial growth. In this context, acetic acid sticks out as the most important inhibitor withconcentrations of 15.2 and 12.5 and 9.7 g/l respectively in the 12 %, 10 % and 8 % (ofsuspended solids) trials. Using pentose fermenting yeast may lead to higher ethanolproduction, lower xylose uptake and lower lactic acid formation.

I denna uppsats undersöks hur användarna på det virtuella nätverket facebook väljer att framställa sig själva samt vad som ger social status därpå, och detta ur ett genusperspektiv. Facebook är ett socialt virtuellt nätverk som baserar dig på relationer förankrade utanför internet, och har på en mycket kort tid nått en stor spridning. Facebook är därför en social arena som möjliggör nya möjligheter men även begräsningar i presentationen av jaget. Uppsatsens resultat baseras på en innehållsanalys av statusuppdateringar och bilder från facebook, som analyserats utifrån relevant sociologisk teoribildning. De resultat som framkommit ur analysen tyder på att den framställning som görs av användarna på facebook är en idealiserad och ytlig sådan, där båda könen strävar efter att framstå som populära, framgångsrika och lyckade.
