En komparativ studie mellan etiska och traditionella fonder : En studie som jämför riskjusterad avkastning mellan etiska och traditionella aktiefonder på den Svenska marknaden 2007-2011
Aim: The aim of this study is to do a comparative study between Swedish Ethical equity Funds with Swedish traditional equity funds in terms of return, risk and risk-adjusted return.Theory: Sharpe ratio and Modigliani-Modigliani.Method: The essay will be based on a quantitative research method in which secondary data is the basis for the calculations. A statistical analysis was applied.Conclusion: The study concludes that there is no significant difference between the ethical fund group and the traditional fund group in terms of return, risk and risk-adjusted returns. The traditional fund group was those who had the best returns but only by small margins..
Profileringsarbete för jämställdhet inom IT-organisationer
During our formative years, technology has always had a natural part of everyday life, and for us technology has never been particularly gendered. If this depends on the climate and the attitude of our homes, ourselves, the combination of both or something completely different is a question we have asked ourselves at times. But our approach to technology does not seem as obvious to all women, and today the IT industry is heavily dominated by men. This has meant that we have asked the question whether there is any underlying reason why so few women opt for IT courses? Is there a link between how different IT organizations profiles and the prevailing gender ratio? The purpose of this study is to investigate whether there is any connections between how IT organizations are related to gender issues and how the structures, attitudes and gender actually looks like in the IT industry today, and how this can be seen in their branding efforts.
Att inleda ett arbete med CRO inom webbutvecklingsföretag
This study test the short-termism of companies listed on the market OMX Stockholm 30. We will use a deductive point of view where the purpose of this study is to investigate whether corporate short-term returns can be explained by the independent variables related to corporate governance and compensation practices. This is to investigate whether there is an intentional action on raising the short-term return in order to achieve a higher CEO compensation. In the study, theories dealing with corporate governance and agency theory have resulted in two hypotheses. Basic Hypothesis H1 is: if short-termism of Swedish industry due to the company's short-term returns can be explained by the independent variables related to the company's management and compensation. This hypothesis could not be verified through the quantitative study. Alternative Hypothesis H2 is: the compensation of a CEO can be explained by the independent variables related to company performance and size.
Trombocyträkning hos katt : en ny metod
Platelet aggregation is a major and common problem in blood samples from cats. This greatly affects the accuracy of counting of the platelets. Because of the difficulties in counting feline platelets, results for patients and reliable reference values for cat platelets are currently so inaccurate as to be almost useless in diagnosis of thrombocytopenia. In this study we used an effective method to prevent platelet aggregation. Blood was collected in CTAD test tubes and prostaglandin E1 was added to the blood sample.
Anhörigas upplevelser av bröstcancer : En litteraturstudie
Syftet med denna studie var att ta reda på om STAVUX (stavningstest för vuxna) och Kasttranskription är lämpliga test att använda vid dyslexiutredningar av vuxna, då det idag saknas sådana test som är normerade på personer över 18 år. STAVUX är ett stavningstest som framtogs av Nilsson och Pettersson (2009) och som består av 45 ord och 45 nonord av varierande svårighetsgrad. Orden är utvalda för att representera svenskans olika stavningskombinationer och nonorden är konstruerade för att följa svenskans ljudmässiga uppbyggnad. En mellangruppsdesign användes för att ta reda på om STAVUX är ett lämpligt test att använda vid utredning av stavningssvårigheter i samband med dyslexiutredningar. Testet validerades på 23 personer med dyslexi i åldrarna 18-64 år.
Postaktiveringspotentiering i knäböj med hjälp av countermovement jumps
Studien avser att studera effekterna av arbetsplatsförlagd fysisk träning 2 x 60 minuter/vecka i 7 veckor hos personer med stillasittande arbete påVO2max, rörlighet, uthållighetsstyrka och kroppssammansättning. Vi använder oss av en kvantitativ metod som består av datainsamling genom tester före och efter träningsperioden för både interventionsgruppen (n=25) och kontrollgruppen (n=11). Resultaten visar på signifikanta skillnader hos interventionsgruppen på variablerna VO2max (p=0), visceralt fett (p=0,001), fettmassa (p=0,001), vikt (p=0.006), Body Mass Index, BMI (p=0,005), uthållighetsstyrka enligt Sörensens isometriska uthållighetstest (SIU) (p=0) och Trunk Curl Static Endurance test (TCST) (p=0,045), rörlighet i halsrygg (p=0,010) och rörlighet i hamstringsmuskulatur via Sit and reach test (p=0). Inga skillnader ses i blodtryck och, skelettmuskelmassa i armar, bål och ben. Inga signifikanta skillnader ses hos kontrollgruppen oavsett variabel. Slutsatser av studien är att man kan se effekter genom denna typ av intervention på flera olika variabler och förslag till framtida forskning är att försöka utesluta samverkan av andra faktorer för att ge en mer exakt bild av den fysiska träningens effekter på arbetsplatsförlagd träning..

The valuation of the application was done by a usability test and an analysis of the results of the test.The application of the thesis has an easy navigation system, which is time saving and simple to use. Finding recipes with the associated ingredients is a quick fix. The search function can be used for searching freely after recipes as well as for separate ingredients. That makes it possible for the user to create own recipes from available ingredients.
Allsidig rörelsekompetens hos barn och ungdomar : En kartläggning av skolelevers funktionella motorik
Gross motor skills among Swedish pupils. An overview of functional motor abilities among Swedish children and adolescents.IntroductionPhysical Education (PE) teachers in Sweden have noticed that pupils are getting worse in their ability to manage gross motor skills and in their aerobic practice. The gross motor skills and coordinative skills are the solid ground for sports and other health activities. If not developing their gross motor skill children tends to avoid taking part in games and sports. The benefits of sports and outdoor activities such as social and health benefits can therefore be missed.
Humant papillomvirus : Gymnasieelevers kunskaper om och attityder till HPV, HPV-vaccin, kondomanvändning och cellprovtagning
Purpose: To assess awareness and attitudes regarding HPV, HPV-vaccines, use of condom and participation in pap-smear screening among high-school students in Uppsala County. The intention was also to investigate if there were any differences between students at theoretical programmes and vocational programmes.Methods: 608 students from seven high-schools in Uppsala County answered a questionnaire covering demographics, awareness and attitudes regarding HPV, HPV-vaccine, use of condoms and pap-smear tests.Results: A majority of the students had never heard of HPV (86 %, n=521), HPV-vaccine (94 %, n=537) or the link between HPV and cervical cancer (88 %, n=563). Most respondents had a positive attitude towards HPV-vaccine (84 %, n=508), but the biggest obstacle was the high cost (37 %, n=227). The students believed that it was less likely that they would use a condom with a new partner if vaccinated (mean=78, SD=26, p<0.001), or if they or their partner used contraceptive pills (mean=62, SD=32, p<0.001) compared to how likely it was that they would use a condom in general with a new partner. The girls rated the probability that they would participate in a pap-smear screening as relatively low if vaccinated (mean=59 SD=27).
Osteometriska Mätningar : För artbedömning av får, get och svin utifrån mått av revben
Ribs from sheep, goat and pig are rarely assessed to species due to the fact that they are very similar in their morphology and size. The ribs are instead considered unidentifiable although it is possible to see what kind of bone it is. If these ribs would be identified to species not only would species assessment degree of archaeological source material increase, the relationship between meat-rich and meat poor regions would change.To find out whether there are morphologically measurable differences between sheep, goat and pig ribs, three measurement points on each rib has been defined and measured. At each measurement point two measurements were measured, one medial-lateral measurement and one cranial-caudal measurement. The ratio between the medial- lateral measurement and the cranial-caudal measurement was calculated for each point.

Background: The Swedish population is aging [1] and malnutrition is a common problem among elderly people [2]. A method called food registration is used to monitor the patients? nutritional intake, with the purpose of reducing the risk of patients deteriorating in nutritional status during hospitalisation. However, the current method is not satisfactory and many food registration lists are incomplete. [3-6] Thus, patients do not receive a qualitative nutritional care since the assessment of the patients? nutritional status is based on incomplete documentation.Purpose: The purpose of this master thesis is to increase the quality in the nutrition monitoring process in the geriatric units B72 and B74 at Karolinska University Hospital in Huddinge, Sweden.
Motivation och läsförståelse : En studie av korrelationen mellan motivationen till att läsa och läsförståelsen hos elever i tredje ring på gymnasiet
This essay, called Motivation and reading comprehension, is a study of the correlation between the motivation to read and the reading comprehension of Swedish students in their final year of school before university level, meaning that they are eighteen or nineteen years old, sometimes more.The relation between the identity of the individual and the learning process has been a matter of scientific interest for some time, and this essay works in that tradition by investigating the connection between how pupils regard reading and how well developed their ability to decode text is.The reading comprehension is measured through a test that consists of a text from the Swedish epic by Vilhelm Moberg, Invandrarna, where the reader at certain intervals throughout the text is asked to mark the correct word from a choice of three. This test has been used and evaluated extensively by Per Fröjd, who has found that the results are reliable and useful.To measure the motivation to read I?ve constructed a survey to be answered before taking the reading test. It focuses on three different parts of reading motivation that are noted as the most important ones by Ivar Bråten. These are the feeling of joy and interest for reading, the goal to acquire knowledge of a specific subject, and the expectations that you have on yourself as a reader.Results show a weak or non-existent correlation between the two factors for the whole of the subjects, but once those who have a first language other than Swedish are removed the correlation becomes significant.
Utveckling och normering av ett stavningstest för vuxna (STAVUX)
Syftet med denna studie var att utveckla och normera ett logopediskt stavningstest för vuxna., då det idag saknas ett sådant test. Det framtagna testet bestod till en början av en orddel som innehöll 80 ord i varierande svårighetsgrad, utvalda för att representera svenskans olika stavningskombinationer. Vidare fanns en del med 80 nonord, konstruerade för att följa svenskans ljudmässiga uppbyggnad. 146 deltagare från 18 ? 94 år deltog i normeringen av testet.
Styrsystem : För en forskningsutrustning
The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.Design and manufacturing of the equipment was handled internally at LIU.The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them.
Direktavkastningens determinanter
Syftet med uppsatsen är att belysa i vilken utsträckning valda faktorer påverkar direktavkastningen i Sverige samt att klargöra huruvida investerare kan använda faktorerna i syfte att uppnå önskad utdelningsnivå. Metoden som har använts är kvantitativt baserad, den empiriska datan är företrädesvis insamlad från databasen Six Trust, tillhandahållen av LINC vid Lunds Universitet. Angreppssättet har varit deduktivt, där teorier har testats genom multipel regressionStudien visar inte på något entydigt signifikant resultat för de undersökta variablernas förklaringsgrad på direktavkastningen. Resultatet motsäger därmed ett flertal erkända forskares tidigare resultat, däriblad kan nämnas John Lintner(1956) som menade att utdelningen i mycket stor utsträckning kan förklaras av företagens vinster, något vi inte finner stöd för. Vid prognosticering av utdelningsnivån hos svenska börsföretag bör undersökta variabler inte ligga till grund för placering..
