Etiska fonder : skiljer sig avkastningen åt mellan etiska och traditionella fonder?
Eftersom det råder osäkerhet kring hur avkastningen mellan etiska och traditionella fonder skiljer sig åt på den svenska marknaden, undersöker uppsatsen detta förhållande. Jämförelsen består av åtta fonder, där de fyra fonder är etiska och fyra fonder är traditionella. Fonderna har matchats med varandra enligt Matched-pair analysis för att säkerställa att det är avkastningen som mäts och att inga yttre faktorer som kan påverka avkastningen inkluderas. Vidare har två statistiska t-test genomförts för att undersöka huruvida resultatet från jämförelsen kan besvara frågeställningen i uppsatsen. De statistiska t-testen har utgått från ett större stickprov som består av 32 fonder, 16 etiska och 16 traditionella, även där matchades fonderna enligt Matched-pair analysis.
?Var ligger en kompromiss?? : Om några andraspråkselevers upplevelser av parskrivning.
The purpose of this study was to investigate the collaboration of four learners of Swedish as a second language during a pair-writing task, as well as their experiences of the process, in order to draw conclusions about how to execute pair-writing in the L2 classroom. The study has found that the establishment of compatible partners are of great importance to achieve success and learning through pair-writing. One of the pairs studied managed to work well together and use each other?s knowledge to improve their text, while the other pair continuosly battled for dominance, which had a negative impact on their performance. The two successful students had enjoyed the task and believed they had learned something from it and that pair-writing can be a useful source of knowledge.
Beteenderesponser hos farmuppfödda minkar (Mustela vison) hållna i stora och berikade burar :
The standard housing of farmed mink provides little opportunities for them to behave naturally and abnormal behaviours such as stereotypic behaviour and tail biting may occur. To prevent abnormal behaviours animals in captivity are often provided with different kinds of enrichments. The aim of this study was to investigate what kind of enrichment farmed mink use when they have several kinds to choose from and to observe if abnormal behaviours can be decreased with a larger cage and a more multifaceted environment.
Totally 20 silver blue, 10 months old female mink were kept in traditional cages (80x30x40 cm) for 7 days and in larger cages (195x80x40 cm) with several types of enrichments for 7 days. The enrichments were wire net- and wooden shelves, wire net- and plastic cylinders, water bath, plastic ropes, branches, straw and tennis balls. One-zero scan sampling on behaviour and choice of place were performed during 3 hours and 20 minutes prior to feeding during 7 days per treatment in April 2004.

Testning och parprogrammering : Går det att effektivisera testning med hjälp av parprogrammering?
The purpose of this study was to investigate the possibility of streamlining the test process by utilizing pair programming. During the process, pair programming has been practiced as is defined by the Extreme programming (XP) software development methodology, with the other aspects of XP discarded. The focus of the testing itself has been toward unit testing. The methods applied has been with an experimental approach where 93 cases were attempted to be solved by either single programmers or pair programmers. What has been investigated in these experiments was the time needed to complete a case, how many test attempts were needed to solve the case, and how high a percentage of the cases were solved.
Effekten av kvävegödsling på gasproduktionen vintertid i boreala sjöar
To investigate effects of nitrogen on in-lake CO2 and CH4 production during winter, three pair of lakes was subject for a fertilizing experiment in which one lake in each pair was fertilized with nitric acid (HNO3) directly into the water column in the summer of 2012. The lakes in each pair are assumed to be morphologically, hydrologically and biologically similar, that is, the non-fertilized lakes are considered references. The pairs do differ in one major way by being progressively less humic, going from around 25 mg/l to 10 mg/l DOC. Sampling and analysis was carried out at the end of the frozen period in 2013. Results show a significantly higher concentration of both CO2 (p<0,001) and CH4 (?=0,1, p=0,053) between impact and reference sites in the two less humic pairs.
Analysverktyg för webbsidor med JavaScript
New technological innovations like tablets and smartphones have a taken significant market share on the web and puts new demands on webpages, the user interface and compatibility among different client devices. The full test of a web-based system prior to the publication is often regarded as an important part of the process to create a complete and successful website. This bachelor thesis investigates the possibility to analyze mobile-adapted web sites using a system that first records the visitor's activities and then replays them for an expert analyst to provide valuable information to developers about how their site can be improved.The essay begins with a litterature study on today's most common web development tools and then examines the possibility to apply them during the development of the analysis tool. The work also describes two methods, pair programming and waterfall method used during the project. Three different evaluation methods are presented and one of the models is applied on the finished system.The project results in a web-based analysis tool written mainly in JavaScript using the jQuery library.
Managementska låneord bland låneböckerna: Om bibliotekariers attityder till marknadsmetaforer på biblioteket
Over the last decades, language in the public sector has changed due to influence from New public management. In this thesis, I seek to investigate librarians? attitudes towards a more businesslike way of speaking about libraries, referred to here as management-speak. For this purpose, I?ve used a modified version of the matched guise technique.
Svensk kod för bolagsstyrnings påverkan på aktiekursen i företag med frivillig tillämpning
Due to a rising debate concerning corporate governance that has caused increasing demands for companies? transparency, several codes of conduct have been introduced. The Swedish Code for Corporate Governance is obliged to companies with a turnover exceeding three billions. There are companies that voluntarily apply the Swedish Code. Possible causes to this phenomenon ought to be that the code for corporate governance conveys legitimacy through the insight into the affairs of a company the public receives, through the report of the corporate governance that is published in the annual report and on the home page of the company.
Identifiering av synkronmaskinsmodell genom SSFR-test
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.
Riskkapitalägande i den svenska välfärdssektorn - kortaste vägen till (skatte-)paradiset
This thesis studies whether private equity owned firms within the Swedish welfare sector distinguish themselves in terms of tax planning and short-termism from a control group consisting of other privately owned welfare firms. For the first time, the comparison is made on the entire welfare sector, between 14 matched pairs within education, health care and elderly care. We use financial metrics associated with tax planning and short-termism in sign tests to examine whether the private equity owned firms differ from our control group. The financial metrics tested are actual and paid tax rates, level of interest, book-tax gap, investments, personnel expenses per employee, and cash earnings. We find that the private equity owned firms in terms of tax planning only differ in the level of interest, while no notable differences are found in terms of short-termism..
Hållning av kastrerade och icke kastrerade försöksmöss i par som en lösning på aggressivt beteende
Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new solution was tested in this paper. The proposed solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.
Hur uppfattas Rolf och Britta? : en attitydstudie kring kommentarer på internet och dess koppling till genus
Denna uppsats är en attitydinriktad genusstudie med fokus på internetkommentarer. Det huvudsakliga syftet är att ta reda på om det finns skillnader i hur människor uppfattar en manlig kommentarsskribent jämfört med en kvinnlig och om dessa skillnader går att knyta till genus, samt om de överensstämmer med tidigare liknande forskning. Metod och material i undersökningen är enkäter inspirerade av matched guise-tekniken, som delats ut till 60 försökspersoner där hälften är män och hälften är kvinnor. I enkäten får försökspersonerna läsa två olika kommentarer där den ena är undertecknad en man och den andra en kvinna. Hypotesen för undersökningen är att tydliga skillnader i uppfattningar av den manliga skribenten jämfört med en kvinnliga ska synas, och därmed följa ett snarlikt mönster som tidigare undersökningar av samma slag.

Är korta spenar ett problem i samband med mjölkning? :
In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats.
This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.
