This paper tests the information Signalling hypothesis on a sample of firms making open market stock repurchases. Using an earnings-based valuation model, we find that a majority of repurchasing firms are undervalued relative to their economic value. This result is consistent with previous academic studies, which claim that undervaluation is the prevalent factor explaining the observed abnormal return following the announcement of a repurchase program. We do not, however, find any evidence that the repurchase is consciously made by management to provide the market with new information. .

The aim with this study is to investigate the market reactions to announcements of special dividends and redemptions in Sweden and thus if these announcements can signal information. This study is an event study, where the event is the day of the announcement of a suggestion regarding issuance of special dividends or redemptions. The abnormal returns were estimated for two samples with the market adjusted returns model, one including special dividend announcing firms and the other redemption announcing firms. The Signalling hypothesis and the hypothesis of a tax induced clientele effect are the most important hypotheses for this study. The efficient market hypothesis is another theoretical base that may explain the market reactions to the studied announcements, especially the pre-announcement activities that may occur.

The purpose of this thesis is to through the analysis of interviews with finance professionals in listed companies answer the question on what lies behind capital structure decisions, and to see how well the prevailing theories fit the answers. This article is an explorative and descriptive hypothesis creating study. We have used a qualitative method to analyse practice through theory. We have conducted telephone interviews with CFO:s and financial executives in Swedish listed companies on how they reason when they make capital structure decisions. We have then thoroughly reviewed the theory and empirical tests of the theories.

System based models of plants rely on descriptions and assigned functions of genes, and currently 50% of the genes in Arabidopsis thaliana has either no assigned function or a function based on homology only. Mitogen activated protein kinases (MAPK's) are key players in cell Signalling and are conserved among eukaryotes, though their targets are highly diverse. A recent study has described a small Arabidopsis protein (80), without homology to any described protein, as a phosphorylation target of the MAPK's MPK3/6. Further work established ?-glucan phosphorylase (PHS) as interacting with 80 and described a delayed senescence phenotype for 80 knock-out plants.

In this thesis, I discuss the impact Swedish national culture may have on Swedish diplomats. This is a qualitative study and I have used theories from studies of international negotiations to compare the oppositional results of those scientists with my interview material. With the help of my interview material from seven Swedish diplomats and five foreign diplomats I have compared their perceptions of Swedish culture, Swedish diplomats and their thoughts about the existence of an international diplomatic culture with well known sceientists of international negotiations. My main question is whether there is an international diplomatic subculture, without any national impact, or not. The mission is to base the thesis with earlier science and then compare and contrast with my interview material.

The matter of CSR and sustainable products has gained an increased amount of interest in recent years as "green products" are becoming a trend with more "eco"-alternatives in the assortment of many retailers. However, among the increasing number of socially oriented customers, it seems that although they claim an increased demand for these kind of products, its easier to "talk the talk" that to actually "walk the walk". This is due to a discrepancy between attitude and behavior, called the attitude-behavior gap. The purpose of this paper is to examine how to overcome this gap by using three different studies to get a nuanced and reality-based view of the problem. The focus within these different studies is on the potential effects inside the store and how information provided has an effect on perceived credibility and purchase intention.

Syftet med uppsatsen är att undersöka om det förkommer underprissättning och om den består de första fem månaderna samt finna sannolikheten för en positiv utveckling efter börsintroduktionen. Eftersom vi har studerat kursförändringar efter börsintroduktioner har vi valt att använda en kvantitativ metodansats i form av en eventstudie. Teorierna behandlar främst förklaringar till varför en underprissättning sker samt hur publicitet och informations asymmetri påverkar prissättningen. Teorier som berörs är bland annat ?Winners Curse?, ?Cascade theory? och ?Signalling theory?.Våra empiriska data kommer främst från bolagens prospekt samt kursinformation från Affärsvärlden och Stockholmsbörsen.

Oxytocin is a hormone which plays a crucial role in many reproductive and behavioural functions. It affects many organs and the classical peripheral targets are the mammary glands during lactation and uterus during labour. Oxytocin receptors have recently been described in a variety of normal tissues and primary cell cultures, but also in neoplastic tissues and established neoplastic cell lines, as breast cancer cell lines. The Signalling pathways and biological effects of the oxytocin/oxytocin receptor system seem to depend on species, type of tissue, physiological versus neoplastic state and receptor location within the cell membrane.The aim of this project was to find out if the cell proliferation in the canine mammary carcinoma cell line CMT-U27 was affected upon stimulation of oxytocin, and to investigate the presence of oxytocin receptors in these cells. The cell proliferation was examined by using an ELISA-kit, where the absorbance measured is relative to the amount of living cells.

Megalaria grossa is classified as Near treatened on the Swedish Red List. It is also a so called signals spieces, e. g. a spieces that function as an indicator, Signalling a forest that is worthy of protection. The aim of this study was to clarify the status at selected localities in the province of Uppland and Gotland.

The escalating usage of pyrethroids has resulted in an increased awareness about resistance towards pyrethroids in insects. Pyrethroids inhibit voltage-sensitive sodium channels (VSSC) in nerve cell membranes and are composed of synthetic molecules based on pyrethrins present in pyrethrum extracts from Chrysanthemum species. VSSC are transmembrane proteins that are important for electric Signalling over the membrane in insects. Mutations in the gene encoding the sodium channel have proved to be a common reason for resistance against pyrethroids. Pyrethroid resistance among pollen beetles is spread all over Sweden and also abroad and is increasing.

One way of Signalling commands to the horse during riding is through applying tension on the reins to create bit pressure in the horse?s mouth (Terada et al., 2006; Clayton et al., 2011). The skilfulness of the rider in using the hands when applying bit pressure has consequences both for the horse?s performance and welfare (Manfredi et al., 2010). At the trot there are large vertical deviations of the horse?s body which the rider must adjust and adapt to (Terada et al., 2006) and an unsteady hand due to inability to follow the horse?s movement can be a source of discomfort and conflict behaviour in the horse (Heleski et al., 2009).

Ovine black coat colour is determined by the MC1R (Melanocortin 1 receptor) and ASIP (Agouti Signalling peptide) genes at the Agouti and Extension loci. The black phenotype is caused by production of eumelanin by melanocytes, whereas yellow-tan or light phenotype is the result of phaeomelanin synthesis. The ovine MC1R gene has two known alleles: the wildtype (E+) and the dominant black (ED) alleles. Two missense mutations (c.218T>A and c.361G>A) constitute ED. The presence of a third allele, the e allele, is proposed and believed to give rise to phaeomelanic phenotype.
