Price transmission dynamics of Chinese ADRs listed on the NYSE

Purpose: This study aims to examine the price transmission among ADRs (American Depositary Receipts) and their underlying shares, US market index and Hong Kong market index. We will attempt to capture how a shock in the home market is transmitted to the foreign (and vice versa). In addition we will attempt to assess the relative weight of each variable in the system generating unexpected variations of its own and other variables and at what speed the shocks are absorbed.Methodology: ADF unit root test, Johansen?s co-integration test, Granger causality test, VECM, impulse response, variance decomposition Empirical foundation: Five Chinese ADRs listed on the New York Stock Exchange. Each ADR represents a specific industry.

Användning av genetiska algoritmer för framtagning och utvärdering av byggordningar i RTS-spel

Detta arbete undersöker användningen av evolutionära algoritmer för framtagning och utvärdering av byggordningar i RTS-spel. Syftet var att undersöka om just evolutionära tekniker kan uppnå lika bra resultat som skriptade byggordningar då evolutionära tekniker oftast är billigare att utveckla.För att undersöka denna problemställning utvecklades en applikation med en experimentmiljö och en Artificiell Intelligens (AI) med evolutionär algoritm. Denna applikation och AI användes sedan för utvärdering av framtagna byggordningar.Resultatet antyder att evolutionära tekniker kan uppnå lika bra kvalitet som de skriptade byggordningarna.Något som krävs i detta arbete är fördefinierade skript för byggordningar för att köra evolutionen men något som skulle vara intressant att kolla på är coevolution. Med coevolution hade det varit möjligt evolvera fram byggordningar utan dessa färdiga skript genom att köra evolutionen mot individer i samma population..

Syftet med denna studie var att undersöka vikten av ett genetiskt föräldraskap hos par som genomgick infertilitetsbehandling i Sverige med donerade ägg eller spermier, samt att jämföra attityder till genetiskt föräldraskap mellan kvinnor och män samt personer med eller utan möjlighet till genetiskt föräldraskap. Denna delstudie ingår i ett större projekt som heter Långtidsuppföljning av IVF, ägg- och spermiedonation i Sverige. Den grupp som har undersökts i föreliggande studie är par som genomgått behandling med donerade ägg eller spermier under 2005-2006. Antalet recipienter i denna studie var 277 personer. Information har samlats in i form av enkäter.

Restriktiv kardiomyopati hos en familj birmakatter :

Cardiomyopathy is the most common type of cardiac disease in the cat. Restrictive cardiomyopathy (RCM) is comparably uncommon and only a few studies have been conducted in this disease. The purpose of this study was to examine the presence and inheritance pattern of RCM in a family of Birman cats. The family comprised 177 known cats. 107 of these cats were examined by echocardiography, 23 of the cats died/were euthanized and a diagnosis could be established post mortem.

"And the World has Somehow Shifted." : En kvantitativ studie av genuskonstruktioner i Walt Disney Pictures animerade långfilmer

The Disney princess line includes nine films, in our study we have extended this line to include the latest three films from Walt Disney Pictures that follow the same pattern. These films are Tangled (2010), Brave (2012) and Frozen (2013). We have conducted our study using the same method used by England, Descartes and Collier-Meeks (2011) in their study of the first nine films, starting with Snow White and the Seven Dwarfs produced in 1937 to Princess and the Frog from 2009. A quantitative study was executed where we focused on gender role portrayal, the main characters behavioral characteristics and performed rescues. We applied the following theories to our result; the Social Constructivism, Laura Mulvey?s theory of the Male Gaze, Michel Foucault?s theory of power and discourse, intersectionality and Claude E.

Andraspråkslärares förhållningssätt gentemot dialekter i uttalsundervisning : En kvantitativ undersökning utifrån två aspekter: kursplan och lärarattityd

Uppsatsens syfte är att belysa kursplaners och lärarattityders påverkan på andraspråkslärares förhållningssätt gentemot dialekter i uttalsundervisningen. Frågeställningarna är uppdelade i utifrån syftets två aspekter och är formulerade på följande sätt: Hur påverkar kursplaner lärares förhållningssätt gentemot dialekter i uttalsundervisningen? samt Hur påverkar lärarattityder lärares förhållningssätt gentemot dialekter i uttalsundervisningen? Undersökningen består av en surveyundersökning och materialet samlades in genom en webb-baserad enkät. Totalt besvarades enkäten av 58 svenska som andraspråkslärare varav 15 har utbildning för arbete mot grundskolan, 16 för högstadiet, 14 för gymnasiet och 13 för SFI (svenska för invandrare). Materialet redovisas i enlighet med statistiska konventioner och analys i form av ANOVA (Analysis of Variance) och Pearsonkorrelationer.Resultatet gällande kursplaners influens visar att det inte finns någon påvisbar skillnad mellan lärargrupperna: grundskol-, högstadie-, gymnasie- och SFI-lärarna gällande deras medvetna påverkan på elevers dialektanvändning och undervisning om dialekter i klassrummet.

Comparison of two methods for evolving recurrent artificial neural networks for

n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.

Genetisk och etologisk analys av vallningsbeteende hos border collie :

The ability of a dog to perform some kind of practical work, for example hunting or herding, depends among other things on its behavioural characteristics. In animal breeding it is not always easy though to select for behavioural traits. It may, for example, be difficult to identify traits that are not only heritable but also of importance for the dogs' ability to perform the practical work of interest. Moreover, it is often difficult to accomplish accurate measurements of behavioural traits. When selecting dogs for breeding, it is usually preferable to evaluate them using an objective and standardized bahavioural test, rather than results from field trials.

Metodfokus på Affekt; Hur känns det?

Evidence-based psychotherapeutic methods compete with each other, while meta-analysis have shown that variability due to different methods related to outcome is remarkably low. In this qualitative study six former patients were interviewed about experiences of method and technique in Affect-focused therapy, with a slight overweight towards unsatisfactory experiences. Responses were analysed and categorised in emergent themes. Methodological focus on affect showed to be a much appreciated, as well as insufficient, element. Alongside positive experiences or summaries of therapy, methodological frames were felt to be at times restrictive, even invalidating, as far as not allowing focus on what was felt to be the more predominant need.

Hepatit E - en zoonos?

Hepatitis E virus, HEV, is a frequent causative agent behind, especially waterborne, infections in developing countries such as India. However, during the last years the number of non-travel-associated infections in industrialised countries, for example US, Germany and Sweden, has increased. The symptoms vary from mild with nausea to icterus and it can even be lethal. There are four different genotypes of HEV and many studies consider HEV infection to be a zoonosis. Scientists have by using phylogenetic analyses found great genetic similarity between strains isolated from humans, pigs and food, such as pork and liver, especially among viruses belonging to genotype 3.

Barn med 22q11.2 deletionssyndromet ? hur hör de?

The 22q11.2 deletion syndrome is a common genetic disorder that affects for example the heart, palate, immune system and hearing and therefore affects a child?s development. The purpose of this study was to investigate the proportion of children (0-18 years) with 22q11.2 deletion syndrome who have a hearing loss. A retrospective study of 103 children diagnosed with 22q11.2 deletion syndrome was conducted by medical records. Of the 103 children, 51 were boys and 52 were girls.

TaqMan® Sample-to-SNP Kit? : evaluation of kit for low-cost and fast preparing of DNA-samples before genotype analysis

 Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .

Evaluation of a new microarray method for genotyping of HLA-DQ2 and HLA-DQ8 for investigation of celiac disease

Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.

En studie om hanteringen av Rasbiologiska institutets samling och känsligt material vid Uppsala universitet

The Swedish institute of racial biology was the first of its kind in the world. The purpose of their activity was to gather information about the different kind of racial characters of the Swedish population. They did this by traveling around the country gathering pictures and statistic information. In 1958 it was decided that the institute was going to get integrated with the University of Uppsala and change its research focus to a more medical genetic. Most of the research material also got integrated into the university?s library.The purpose of this paper is to find out how the institutes collection has been handled through the ages and if there have been any controversy or debate about it.

Design of Production Contracts : an examination of the Findus pea production contract

The Swedish processor Findus contracts approximately 500 pea producers annually to secure the company?s supply of green peas for human consumption. A production contract, which has had roughly the same design for decades, regulates the relation between Findus and the pea producers. Agriculture is typically a risky business. The main sources of risk in agricultural production are production risk and price risk.
