Word of Nextopia - en djupare förståelse av Nextopia och hur det påverkar Word of mouth
The purpose of this study is to further develop the understanding of Nextopia, the belief that the next product will always be better, and the effects it has on Word of mouth, both oral (WOM) and electronic (eWOM), and investigate possible causes of this effect. This has been made through an experimental study of responses to two mineral water ads, with a manipulated time frame. First, this thesis supports the fact that there is a general Nextopia-effect on customers being exposed to a future product, which makes them evaluating the product higher in terms of feelings, attitude and intention. Further this study shows that there is also a Nextopia-effect on WOM and eWOM, by customers being more likely to recommend a future product rather than a current one. This propensity to recommend the product also has a relationship with responsibility, which correlates much stronger with WOM than eWOM.
Predatorinducerad fekunditet hos Daphnia pulex vid simulerade årstidsbundna temperaturvariationer
Female growth, number of eggs and egg growth of Daphnia pulex were studied at four temperatures, 12, 16, 18 and 20°C. I hypothesized that female growth and number of eggs would be lower and the size of the eggs larger in the presence of a predator (kairomones) than in its absence. This effect was expected to be more evident at lower temperatures. I could not find any effect of kairomones on female growth, number of eggs or egg size, although there was a weak tendency for an effect on number of eggs. There was, however, an effect of temperature, regardless of predator treatment (i.
Narkotikans effekter på övrig brottslighet : En analys av svenska paneldata på länsnivå 1995-2004
Under senare hälften av 1990-talet har narkotikamissbruket i Sverige ökat. I denna uppsats undersöks huruvida detta har påverkat den övriga brottsligheten genom en analys av data frånen panel bestående av samtliga svenska län 1995 ? 2004. En Fixed-Effects- modell som kontrollerar för läns- och tidsspecifika effekter har anpassats till datamaterialet. Måttet på narkotikakonsumtion är baserat på den årliga enkätstudie som genomförs bland 18- åriga män som mönstrar till värnpliktstjänst i Sverige.
Inverkan av den genetiska defekten Complex Vertebral Malformation på fruktsamheten hos SLB :
Complex Vertebral Malformation (CVM) is an autosomal recessive inherited defect in the Holstein breed. The defect has lead to structurally malformed calves and losses of pregnancies. To determine the effect of CVM on fertility in the Swedish Holstein Breed 375 Holstein bulls used in breeding by Svensk Avel and Skånesemin were assigned to this study. 228 bulls matched the criteria of birth year, 1995-1999, > 75 inseminations and a known CVM-status. Of the total 228 bulls 53 of them were CVM-carriers and 175 were non-carriers.
The SAS-programme was used to determine the effects of CVM-status, the bull?s father and birth year on Non-return rates (NRR) for 28, 56 and 168 days.

Indexeffekten : En studie gjord på Nasdaq OMXS30 och OMXH25
AbstractMaster thesis in Business Administration, School of Business and Economics at Linneaus UniversityAuthors: Patrik Larsson and Pontus GislénSupervisor: Håkan LockingExaminer: Sven-Olof CollinTitle: The index effect- a study on Nasdaq OMXS30 and OMXH25Introduction: A significant part of the financial literature is based on the Efficient Market Hypothesis which assumes that prices in the market reflects all available information. Anomalies, such as the index effect, indicate weaknesses in this theory as it has been proved that it is possible to outperform the market using public information. Hence, the index effect can be linked to market efficiency which makes it interesting to study from a theoretical perspective. The mapping of the index effect is also interesting from a practical perspective, as it leads to a better understanding of whether investors and firms should take this anomaly into account.Problem: Is there an index effect, how does it behave and what can explain this effect?Purpose: The aim of this study is to investigate the index effect.

Dexametasons effekt på trombocytaggregering och syreradikalproduktion
Platelets are important for the healing of damaged blood vessels since they have an importantpart to play in the coagulation process. At the same time, the blood must be kept fluid and notcoagulate at the wrong time. Therefore there are factors that effect the aggregation of plateletsin a positive or a negative way.Previous investigations have shown that platelets during stirring conditions produce reactiveoxygen species (ROS) that weaken the inhibiting effect of nitric oxides (NO) on platelets andthat the drug Dexamethasone (Dex) can reduce the ROS-production.The aim of this project was to investigate if glucocorticoids, in this case Dexamethasone,could restore the inhibiting effect of NO on platelets and if there was any decrease in ROS-production.The result of the ROS-measurements showed a great variance and it was difficult to draw anyconclusions from them, but a clear decrease in ROS, as previous reported, was not shown. In the aggregation experiments the inhibiting effect of NO was observed through the drug S-nitroso-N-acetylpenicillamine (SNAP), a NO-donator.From the aggregation experiments, the result seemed to be that SNAP during longerincubation time lost its inhibiting effect, probably because the cells become desensitized.With superoxid dismutase (SOD), the effect of SNAP increased, both in the experiment withlonger and shorter incubation times. Dex seemed to reinforce the aggregation in relation toboth SOD and SNAP.
Kapitalstruktur i svenska små och medelstora företag
The purpose of this study is to investigate the determinants of capital structure in Swedish small and medium sized firms. The study includes 24.859 Swedish firms which are further analyzed with regards to their financial characteristics. These characteristics consist of short term debt, long term debt and total leverage. The study compares the relationship between these characteristics and six independent variables.The result shows that profitability is the greatest determinant for capital structure in Swedish small and medium sized firms with regards to total leverage. When profitability increases the total leverage of the firm decreases.
Alkoholvanor inom det gymnasiala fordonsprogrammet
The consumption of alcohol in Sweden has increased considerably within recent years. Among youths there has been a tendency towards drinking more frequently and increased volumes. Alcohol habits among students on the high schools auto mechanic line has been given a questionnaire to examine their experience of the immediate after effect of alcohol and how et effects their situation in school. It has been proven that participating students are drinking alcohol more frequently than the average among Swedish high school students and girls more often than boys. The general experiences of alcohol after effect are predominantly negative both physically and psychologically, but the students are not concerned of their alcohol habits having an effect on their school work..
Fosforgödslingseffektivitet i långliggande bördighetsförsök
Rapid population growth and the fact that phosphorous is a limited resource implies that the question regarding an efficient use of phosphorus is of great importance, and consequently,that the phosphorous use efficiency should be as high as possible. The view on phosphorous use efficiency, and how this is calculated, has varied over time. This has had great implications on what type of research that has been conducted, which have resulted in an
inconsistency between the academic?s view on the subject and recommendations received by farmers. The purpose of this paper is to calculate the phosphorus use efficiency in the Swedish long term fertility experiments.

Valet av Renegade och Paragon i Mass Effect : Undersökning av möjliga aspekter på valet att spela som ond eller god med fokus på spelarens subjektiva upplevelse
The purpose of the study was to examine possible aspects concerning the choice to play as good or evil with a focus on the players´ subjective experience. A form was constructed and the material was interpreted according to Interpretative Phenomenological Analysis (IPA). The games Mass Effect I and II were used as an example of the choice to play as good or evil since the choice between Renegade (evil) and Paragon (good) is present. The sample consisted of individuals who had played Mass Effect I and/or Mass Effect II and were over 18 years old. The end result concerning who played a Renegade or a Paragon came to be very uneven (15 out of 16 participants played a Paragon) which means that the result mostly relates to possible aspects concerning the choice to play a Paragon.
