Drawing on theories of ethnic representations in mainstream news media and racial discrimination (van Dijk 2000, Hultén 2006, Husband & Downing 2005, Wodak 2011), and using methods of critical discourse analysis (mainly van Dijk 1993, 1991, Fairclough 1995) this bachelor thesis aims to investigate the inter-textual and inter-discursive relationship between selected editorial and opinion pieces written by three mainstream right wing ?symbolic elites? and the xenophobic blog ?Avpixlat?. The three selected symbolic elites are: Per Gudmundsson, editorial writer at the second largest Swedish newspaper SvD, Andreas Johansson Heinö, academic with a P.H.D. in political science, specialized on issues of integration and ethnic relations, and Paulina Neuding, editorial writer at SvD and editor in chief for right-wing oriented magazine Neo. All three are actively taking part in the mediated discussion of ethnic relations in Sweden from a liberal-conservative perspective.

The aim of this Master thesis was to examine news journalism covering expressions of mourning related to violent or unexpected deaths. What rituals for mourning are brought out in media and do media present guidance to how mourners should behave? The questions examined were: What characterised news events that leaded to texts on expressions of mourning? How was grief framed? Which narrative patterns were there in the texts? How was the deceased represented? How were the mourners represented? 165 texts, from Swedish daily newspapers, covering 93 different news events were analysed. The methods were mainly discourse analysis with focus on identities and relations, but also semiotic analysis with focus on staging and symbols and narrative analysis with focus on patterns for storytelling. The result showed that a news story about ordinary people expressing their feelings of grief has elements of melodrama. The news story is based on the myth of the victim, and formed as a typical story where equilibrium is disturbed when the inconceivable happens and the mourners can by their actions restore equilibrium.

The virus-mediated disease Rift Valley fever (RVF) was discovered during an outbreak in Kenya in the 1930s. Since then it has spread to most parts of Sub-Saharan Africa, and in the last decades several outbreaks have caused economic and health issues in Africa, Yemen and Saudi-Arabia. The disease mainly affects domestic livestock, causing abortions, but is also a zoonosis. To be able to control the spread of the disease it is important with surveillance for better knowledge about the distribution and virus circulation even in inter-epidemic/epizootic periods. The human population is growing, and people and their livestock constantly move closer to areas with wild animals which act as reservoirs for different viruses. Also, humans and their animals often get within reach for arthropod vectors, hosting or carrying viruses.

Equine metabolic syndrome (EMS) it?s a clinical condition that includes obesity, regional adiposity, insulin resistance (IR) and laminitis. A similar syndrome exists in human medi-cine, the metabolic syndrome (MS), were systemic hypertension also is a prominent fea-ture. The systemic hypertension seen in humans with MS is partly due to a vascular endo-thelial dysfunction with an enhanced endothelin-1 (ET-1) mediated vasoconstriction. There are indications that systemic hypertension might be a feature in EMS as well but if ET-1 is involved in the development of the systemic hypertension in horses is not known.

Immunmedierad trombocytopeni (IMT) är en vanlig rubbning i primära hemostasen och uppstår som en konsekvens av för tidig destruktion av trombocyter (blodplättar). Denna destruktion beror på en ökad produktion av trombocytbundna antikroppar (platelet-bound antibodies, PBA) som binder in till antigen i trombocytväggen. Antikroppsproduktionen, som är en immunologisk process, kan dels uppstå spontant genom en autoimmun reaktion (primär IMT), eller triggas av infektioner eller neoplasier (sekundär IMT). Diagnosticering av IMT, och då syftas framför allt på primär IMT, sker främst utifrån uteslutande av andra bakomliggande orsaker, då en specifik diagnostisk metod inte finns tillgänglig. Tester för att påvisa PBA finns, men deras betydelse för både diagnostik och prognos har länge varit oklar. Denna uppsats syftar till att sammanfatta forskning som finns tillgänglig om betydelsen av påvisande av PBA vid IMT, men även forskning kring den immunologiska bakgrunden till sjukdomen.

Ett par år in på 2000-talet präglas företagen av större marknader, globalisering och ökat fokus på IT. Mycket pengar går åt till resor världen över när man öppnar kontor, besöker fabriker eller utökar sina marknader. Man arbetar i globala team och utnyttjar kunskaper och erfarenheter som andra kulturer har. När lågkonjunkturen kommer får man tänka om, och man drar ner på både personal och resor. Hur fungerar det när man måste fortsätta sitt arbete men inte får resa som man gjort förut? Går det att fortsätta i vanlig ordning? Vad händer när man nu inte kan träffa sina kollegor, mötas och interagera som man brukade göra?Enligt Nationalencyklopedin har vi en inre drivkraft att kommunicera, att göra oss förstådda och att interagera med andra människor.

Atopic dermatitis (AD) is a complex, often lifelong allergic disease affecting around 10 % of both dogs and humans. The hallmark symptom is severe pruritus, causing a lowered quality of life. Mast cells (MCs) are known to play an important part of the immunopathogenesis, promoting a faulty T helper cell type 2 (Th-2) response which follows by a production of specific immunoglobulin E (IgE) antibodies towards environmental allergens (Ag). To further investigate the role of MCs and its mediators in the progression of AD, a low-calcemic vitamin D3 analog (MC903) was used to induce AD-like symptoms locally on the ears of two different knock-out (KO) mouse strains. The first strain was Wsh-/- mice deficient in MCs.

Diabetes mellitus is a rising epidemic throughout the world and there is currently great interest in quantifying the beta-cell mass (BCM) in vivo non-invasively. In the present experiment, the feasibility of in vivo imaging of the glucagon-like peptide-1 receptor (GLP-1R) in beta-cells was examined, using the positron emission tomography (PET) tracer [68Ga]Ga-DO3A-VS-Cys40-exendin-4 as a marker, in native pancreatic beta-cells of a porcine diabetic animal model and healthy controls. Eight Swedish high-health domestic pigs were randomly assigned to be either controls or made diabetic using streptozotocin (STZ). The experiment proceeded during eight weeks, starting with an acclimatisation period. Once the pigs had been socialised they underwent surgery for the insertion of a jugular vein catheter, allowing induction of diabetes with STZ, intravenous (i.v.) injections and stress-free blood sampling. Development of diabetes was confirmed by clinical examinations, blood glucose values and insulin-staining of pancreatic sections post mortem. The diabetic pigs were insulin treated and responded well.

SyfteSyftet med studien var att undersöka kommunikativa processer som utspelade sig i klassrumsmiljö, mellan elev med autismspektrumtillstånd och annan kommunikationspartner. Den empiriska undersökningen utgick från fem frågeställningar som berörde vilka konstellationer informanterna deltog i, språkets verbala och ickeverbala uttryck, initiering och upprätthållande av kommunikation, i vilka aktiviteter kommunikationen ägde rum och dess innehållsmässiga karaktär och slutligen kommunikationens kvalitet i förhållande till Mediated Learning Experience (MLE). TeoriStudiens teoretiska inramning utgörs av sociokulturell teori, samt teorier kring kommunikation och autismspektrumtillstånd. Sociokulturell teori bygger på uppfattningen att kunskap byggs genom interaktion mellan människor och mellan människor och kulturella kontexter och språket är ett grundläggande redskap i denna process. Teorierna kring kommunikation och autismspektrumtillstånd avser att beskriva olika perspektiv som utgångspunkt för att studera de kommunikativa processerna.

The mouse (Mus musculus) is the most commonly used mammal in biomedical research and can easily be restrained by both hand and by a device. Restraining animals causes stress that not only decreases the animal?s wellbeing, but may also influence the research results. The first aim of this study was to train mice to voluntarily stand still using positive reinforcement training. Another benefit of teaching a mouse to stand still is that you can avoid anaesthesia for some procedures.

High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals. Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.
