Högbeläggningssystem för frigående värphöns : erfarenheter 2011

The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The Sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small Sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.

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. .

Comparison of four transport systems for enetric pathogens

ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological Samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.

Kvinnliga arbetstagare i sjuk- och äldrevården - faktorer som kan påverka graden av upplevd stress utanför arbetstid

The aim of this study was to examine the relations between women?s perceived stress off the job (dependent variable), responsability for household chores, emotional support, number of children living at home, neuroticism and age (independent variables). Comparisons between the present Sample and two independent Samples from previous research were made with regard to perceived stress and neuroticism. The Sample of this study consisted of 186 women working in the fields of health care and geriatric care. The results showed that perceived stress correlated positively with neuroticism and number of children and negatively with emotional support, though the effectsizes for number of children and emotional support were fairly small.

Konsten att förutspå konjunkturen - Hur användbara är enkätbaserade snabbindikatorer?

Foreseeing future changes in economic activity is of up most importance to a wide array of actors. The time lag in the presentation of official GDP statistics means that to somewhat accurately capture a tendency of where the business cycle is heading one need turn to qualitative sentiment indicators such as Purchasing Managers? Index (PMI) and official sentiment indicators for valuable clues. This thesis uses in-Sample and out-of-Sample methods to evaluate how well PMI and official Business Tendency Surveys (BTS) in Sweden and Denmark fair against the year-on-year growth rate of industrial production. Moreover, various Swedish regional sentiment indicators get examined and a case study of the indicator for the Öresund region is performed.

Driver valutakursen, energipriser och subventioner livsmedelspriserna?

Den här uppsatsen visar att valutakursen och sekundärt energipriser har en hög förmåga att prediktera framtida rörelser i livsmedelspriser, både ?inom Sample? och ?utanför Sample?. Uppsatsen använder VAR-modeller och hittar empiriska belägg för att energipriser påverkar valutakursen (EUR/USD), som även indirekt påverkar livsmedelspriser. Teoretiskt och empiriskt visas att export- och produktionssubventioner reducerar eller ökar de ursprungliga priseffekterna vid chocker i valutakursen, och introducering av dessa samband visades öka precisionen av prognoserna. Resultatet är intressant för policybeslut eftersom identifieringen av vad som driver livsmedelspriserna visar att chocker i valutakursen har en omfattande effekt på framtida livsmedelspriser. .

Analys av fysiskt och administrativt flöde för provhantering vid Höganäs AB

In this project, we are studying the material flow and the information flow of Sample materials and the appurtenant report of deviation for the purpose to be able to suggest better solutions. The Sample material, which is to be analysed, is to be continuously taken from the production flow. The purpose is to navigate the process by the results found by the analysis. Because of this, it's very important that both methods of analysis are ensured and that the Sample material is representative for the production flow. However, even more importantly, is that activities and transportations, combined with both flows, must perform in a quick and correct way in order to maintain or improve Höganäs AB's competitive strength.According to reports are about 20 products per day not available, for loading, at the time of delivery.

Anabola Androgena Steroider : En analys om hur AAS skildras i svensk media

AbstractTitle: Anabolic Androgenic Steroids ? An analysis of how AAS is portrayed in Swedish media.Author: Jens SundénTutor: Philip LalanderKeywords: AAS, Anabolic steroids, social problems, media, drug abuse, genderThe purpose of this study was to investigate how Anabolic Androgenic Steroids (AAS) are portrayed and described in the media, how AAS is constructed as a social problem, and how society in a social context uses knowledge and power for disciplinary and educational means. The study is based on the perception of AAS as a constructed social problem and analyzes the discourses surrounding AAS depicted in three Swedish newspapers. The Sample was prepared on the basis that it represents different aspects of daily Swedish press. The method used in the paper is a discourse analysis with social constructivism and gender as theoretical tools used to analyze the Sample material.

??Tidsserieanalys över svensk varuhandel januari 1975 ? augusti 2010

Syftet med denna uppsats är att modellera och prognostisera Sveriges varuexport, varuimport och handelsnetto. Vi använder oss av data från januari 1975 till och med augusti 2010 för respektive serie. Dessa data testas och jämförs i olika ARIMA- och SARIMA-modeller samt skattas även medelst säsongsreningsprogrammet TRAMO/SEATS. För de modeller som bäst passar serierna genomförs därefter in Sample- och out of Sample-analyser med felmåtten RMSE och MAPE. Modellerna med bäst felmått och som därpå väljs ut för att göra prognoser för serierna till och med augusti 2012 är (3,1,0)x(0,1,1) för export, (2,1,1)x(0,1,1) för import samt (0,1,1)x(0,1,1) skattad i TRAMO/SEATS för handelsnetto..

En empirisk studie av Value-at-Risk-prediktering med hjälp av GARCH-modeller

This paper describes a study examining four different GARCH models AR(1)-GARCH(1,1), AR(1)-EGARCH(1,1), AR(1)-APGARCH(1,1) and AR(1)-GJR-GARCH(1,1), and their ability to predict future volatility and thereby providing more reliable estimates for Value-at-Risk. The study is based on daily observations for the return of the OMX Stockholm 30 Index, during the time period 31st December 1996 to 29th December 2006. The coefficients for these GARCH models have been estimated using a five-year rolling estimation window, with one-year lags, for five different in-Sample-periods. These five in-Sample-periods, and the coefficients given by them, have been used to generate five out-of-Sample predictions for the volatility in each year. Using these volatility predictions, the daily Value-at-Risk has been calculated for confidence intervals of 90 percent, 95 percent, and 99 percent, respectively, during the time period between 1st January 2001 and 29th December 2006.

Vilseledande Underhållning : Ungdomars Attityder till Dold Viral Marknadsföring

In this paper, we examine the attitudes of 16- to 19-year olds towards stealth viral marketing in the form of videos posted on websites such as Youtube. Apart from their general attitudes towards the phenomenon, we were also concerned with their views on the ethics involved in this marketing method and how this affects their view on the companies behind the advertising. To accomplish this, we administered a survey to a Sample chosen by convenience. Using the Persuasion Knowledge Model and prior research on the subject, we then analyzed the gathered data and reached the conclusion that the respondents in our Sample were mainly positive towards stealth viral marketing in this particular form, that they generally did not consider it unethical and that even though most considered the companies to be responsible for such videos, teenagers were not likely to take negative actions against them if they found out that a video that they had seen was in fact a stealth viral video..

Hur elever läser - En jämförande studie av gymnasieelevers lässtrategier i biologi och engelska; How students read - A comparative study of high school students? reading strategies in Biology and English

The purpose of this study was to identify reading strategies used by high school students when reading textbooks and school-related material. Any differences in reading strategies between Biology and English were also of importance. A study Sample of 62 students from three different high schools in Sweden participated in the study and were asked to fill out a survey questionnaire. Eight students from this Sample were also interviewed. The findings of this study show that students use a number of different reading strategies of which metacognitive and sociocultural factors play a crucial part.

Ledningsprognosers egenskaper - Hur påverkar de mängden Earnings Management

The purpose of this paper is to investigate the relationship between Earnings Management (EM) and certain characteristics of management forecasts, among a Sample of Swedish listed companies. The forecast characteristics studied are: 1) Forecast venue: How explicitly is the forecast presented? 2) Forecast precision: How detailed is the estimated number? 3) Forecast measure: Which measure(s) are forecasted? We use a Sample of 68 annual management forecasts, obtained from year-end reports between the years 2007-2011. EM during the forecasted year (2008-2012) is estimated using the cross-sectional modified-Jones model. The forecast characteristics are then related to the degree of EM during the forecasted period.
