Den här studien undersöker hur val av examinationssituationer påverka elevernas prestation i matematik. Syftet är att undersöka hur elever presterar utifrån olika bedömningssituationer. Vi använde oss av en empirisk studie där 12 sextonåriga elever i årskurs 9 genomförde uppgifter i decimaltal från Nationella prov för årskurs 9, år 2009.  I studien använder vi oss av både kvalitativ och kvantitativ data. Data samlades in vid två tillfällen med hjälp av skriftligt test och med hjälp av deltagande observationer under ett muntligt test i par. Hermeneutiken ligger till grund för tolkning av den kvalitativa data.

Denna uppsats syftar till att studera hur ett analysföretag kombinerar kvalitativa och kvantitativa data i en marknadsundersökning. Uppsatsen bygger på en fallstudie av en marknadsundersökning utförd av analysföretaget United Minds mellan juni och december 2011. Data har samlats in genom tre djupgående semistrukturerade intervjuer med medlemmarna i projektgruppen på United Minds och innefattar även internt material som tilldelats från projektgruppen. I studien framgår det bland annat att projektgruppen kombinerat olika dataformer på ett mer dynamiskt och kreativt sätt än i traditionell akademisk forskning, att olika datainsamlingsmetoder kan prioriteras olika beroende på vad syftet med metoden är i det specifika stadiet samt att forskare kan effektivisera undersökningar genom att utföra så många studie-moment som möjligt sekventiellt. Uppsatsen ger nya perspektiv för både praktiker som akademiker inom det relativt okända området blandade metoder..

This study was performed in order to evaluate if the method of collecting uterine secretion by the tampon-method is representative for use in studies of uterine secretions in mares. Uterine secretion collected by tampon in six mares was compared with secretion collected by aspiration, regarded to be a native sample, at the Institution of Obstetrics and Gynaecology, SLU, Uppsala. Proteinanalysis was made at the Department of Farmaceutic Bioscience, toxicological unit, Uppsala University. Cytological smears and ultrasonography was used to assess if the tampon had caused an inflammatoric reaction that could influence the protein content of the samples. The results suggest that the tampon and aspirat method do not differ when it comes to proteinconcentration, but the distribution of proteins differ between these different collection methods. This difference could not likely be explained by means of proteins due to an inflammatory reaction from the tampon, since neither the cytological nor the ultrasonographical examination gave any indications of inflammation.

The aim of this paper is to study intra household allocation of capital income by using data on Swedish observations. The 1991 tax reform was to change the taxation on capital income from a progressive to a flat tax system. Before the tax reform there were incentives to allocate capital income to the spouses with the lowest income of labor in order to reduce the total tax burden. The data describes the year of 1989 and 1993, those we choose to examine. Using Swedish data from LINDA database we estimate a quotient by ordinary least squares (OLS) regression.

The agriculture in Sweden today uses chemical substances to control vermin, weed and diseases. This usage shows through polluted subsoil water and trace elements in the food we eat. There?s a risk that additional symptoms will arise in the future. Our product Sha Jun, developed in 2006-2007, is an attempt to try and minimize the need of chemicals in the agriculture. The idea started with the attempt to minimize the usage of pesticides on the cropland.

I denna rapport har mätningar från en lidar och mätningar från en meteorologisk mätmast jämförts. En undersökning har även gjorts för vilka atmosfäriska tillstånd som lidarn mäter bra och för vilka förhållanden den mäter mindre bra. Som referens används data från en mätmast, som antas vara korrekta. Platsen för mätningarna är över skog vilket medför mer komplex terräng än över plan mark.Olika filter har utvecklats för de atmosfäriska tillstånd då lidarn mäter sämre, för att filtrera bort de mest extrema förhållandena. Dessa filter filtrerar bort data med för mycket turbulens, låg eller negativ vertikal vinddifferens och liten återspridning.

Sahlgrenska Academy at University of Gothenburg Department of Internal Medicine and Clinical NutritionAbstractTitle: Can probiotics prevent atopic dermatitis in children with high risk?Author: Laura Pienihäkkinen and Max OlinSupervisor: Heléne Bertéus ForslundExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2012Background Allergic disease is today common, this including atopic dermatitis, which is the most common inflammatory skin disease in the world. Heredity has been shown to play a major role in the development of this disease. It is therefore of high interest for both the individual and society to find effective methods for preventing atopic dermatitis in individuals with high risk profile. Probiotics are beneficial for the bacterial profile in the intestine and it is therefore of interest to study if they through their anti-inflammatory effect could prevent atopic dermatitis.Objective The aim was to study whether administration of probiotics to the mother and the child (directly or via breast milk) could prevent atopic dermatitis in children with high risk profile (at least one first degree relative with a diagnosed allergic disease).Search strategy A systematic literature search was done in databases PubMed and Scopus with search terms maternal, prenatal, probiotics, allergy, atopic dermatitis, prevention, and children.Selection criteria Randomized, controlled human studies and original articles in English were included.

There are about 700 000 dogs in Sweden. Roughly 70 % of the dogs are purebred and registered in the database at the Swedish Kennel Club (SKC). The database includes records of birth date, pedigree, offspring and results from e.g. veterinary examinations related to genetic health programs.Every year approximately 10% of the dogs die; most are euthanized by a veterinarian. Dog mortality data is stored as digital medical records at animal clinics and in insurance databases.Dog owners tend to register their puppy in the SKC, but they rarely report that the dog has passed away.

I denna studie undersöks två algoritmer för att rendera volumetrisk data. Studien syftar till att undersöka om det är möjligt att använda dessa algoritmer i en datorspelsmiljö. De båda algoritmerna, som kallas för shear-warp-algoritmen och footprint-algoritmen, jämförs mot varandra för att ta reda på vilken som är bäst på att lösa uppgiften. Algoritmerna testas också för att se om de är lämpade att verka i en datorspelsmiljö med avseende på om de kan generera tillräckligt antal bilder per sekund.Resultatet av studien visar på att ingen av de två algoritmerna är lämpade inom den domän de är tänkta att verka inom. Även om shear-warp-algoritmen är effektivare på att lösa sin uppgift än vad footprint-algoritmen är så visar studien att ingen av dessa två algoritmer är lämpade i den domän de är undersökta i..

I den här uppsatsen beskrivs en ansats till att med hjälp av statistiska metoder förutse utfallet i förmögenhetsra?ttsliga dispositiva tvistemål. Logistiska- och multilogistiska regressionsmodeller skattades på data för 13299 tvistemål från 5 tingsrätter och användes  till att förutse utfallet för 1522 tvistemål från 3 andra tingsrätter.  Modellerna presterade bättre än slumpen vilket ger stöd för slutsatsen att man kan använda statistiska metoder för att förutse utfallet i denna typ av tvistemål..

ECG-Screening for young elite athletesAbstractBackgroundSudden cardiac death (SCD) during physical activity is a frightening and emotional tragedy that draws huge media attentions when it occurs. Fortunately it is a relatively uncommon occurrence but happens nonetheless to young athletes who often seems to be in perfect health. SCD is used as a term for sudden unexpected complications on the cardiovascular system that leads to a deadly outcome normally within the first hour of onset of symptoms and the cause is some sort of underlying cardiovascular disease that gets triggered by physical activity.Normally athletes gets divided into two groups dependent on age, over and under 35 years, and this studies focus is on the younger group since it is often during this period athletes are at the elite level. It is also in this category the most unexpected sudden deaths occur that is not due to coronary atherosclerosis, which is the dominant cause of death, and drastically increases, for people over 35 years old.AimThe aim of this study was to scientific and unbiased analyze peer-reviewed clinical articles todescribe the pros, cons and cost to implement an ECG-screening as a standard before physicalactivities for specifically defined elite athletes.MethodA systematic review was performed and after all Data collection 21 articles was chosen to beused as a base for both background and analyze. At the end 10 articles was fulfilling the criteria to be used at the analyze and later the results.ResultsThe implementation of ECG-screening has reduced SCD in Italy by 89 % between the years 1979-2004.

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

Denna rapport beskriver VisMT 2. VisMT 2 är en programvara som utvecklats som ett examensarbete av Daniel Peterson vid Linköpings Universitet i samarbete med organisationen NVIS (Norrköpings Visualiserings och Interaktionsstudio).Målsättningen för VisMT 2 var att skapa en enkel och kraftfull mjukvara som på ett innovativt sätt synliggör resultat och prestanda för butiker i detaljhandelskedjor. Vidare sattes målet att programmet skulle grunda sig i ett explorativt gränssnitt där användaren kan undersöka butiksrelaterade data i både spatial och temporalplanet.Programmet gavs ett gränssnitt med sammanlänkade vyer. Interaktion i en vy ger återkopplingar för relaterade data i en annan vy i realtid.Programmet utvecklades i C# .NET och använder Managed DirectX för att generera 3D-grafik. Det slutgiltiga resultatet uppfyller väl den målsättning som skapades vid projektets inledning.

One of the main goals of the national curriculum is to encourage children?s personal opinion and support them in development of argumentation ability and communication skills. All this is very important for the children as members of the future society.The purpose of this essay is to investigate how primary school teachers estimate the meaning of the pupil?s argumentation as well as which methods and approaches are assumed by the teachers to be most appropriate for children?s argumentation development. The study also considers the questions how the teachers motivate their pupil has to argue in the classroom and how the students by themselves understand the concept of argumentation.
