Hasselapedagogy mission in society, as a collective activity, is to help young people in LVU-care.

Animal welfare is impaired if the diet does not provide sufficient feeling of satiety or the ability to perform natural feeding behavior. Pigs are omnivores and spend most of the day searching for food by rooting, grazing and chewing. Both inability to perform foraging behavior and insufficient feeling of satiety often leads to direction of foraging behavior towards stereotyped and abnormal oral behavior. Dry sows are often fed restrictively which leads to unsatisfied feeling of hunger. Dietary fiber has been found to reduce stereotypic and Abnormal behavior as well as aggression, which could indicate that pigs need to forage has been met giving a feeling of satiety.

The purpose of the study is to investigate whether insiders generate an abnormal return compared with other investors on the Swedish Stock Market.

The other purpose is to investigate whether it would be profitable for ?outsiders? to mimic the transactions of insider trades. The results indicate several significant abnormal returns on insider trades, especially on buy transactions.

The purpose of our study is to find out if insiders in Sweden generate abnormal earnings through insider trades. We want to pinpoint the cause for abnormal earnings by dividing transactions after company market value, size of the trade and type of insider. A quantitative approach using the market model have been used. We have conducted an event study over two short term event windows. We conclude that insiders in Sweden generate positive abnormal earnings for sales and negative for purchases in our ?long? event window.

This study aims at examining if abnormal returns have existed on theSwedish stock market surrounding the ex-dividend period between the years2002 and 2006. The ex-dividend period that is studied is the ex-dividend dayplus the following five days. The stocks that have been studied are the thirtymost traded stocks which together constitute the index OMXS30.Furthermore, the study investigates if the size of the dividend has an effecton the size of the abnormal returns.Previously performed studies on both the Swedish stock market and foreignstock markets have shown that abnormal returns exist during the ex-dividendperiod. However, the results from these studies are not unambiguous, why itis interesting to follow up these studies with a new study.The method used for investigating the existence of abnormal returns aroundthe ex-dividend period has taken its starting point in the previouslyperformed studies. However, some changes have been made in order tocalculate for differences in risk between different stocks (using beta) whichhas been neglected in the previous studies.The results of our study are that abnormal returns have existed for four outof six days in the ex-dividend period when calculating a mean value over allfive years.

This paper is an event study on Initial Public Offering?s return behavior after the dot com bubble. Cumulative Abnormal Returns are used to measure the performance against a market index.

Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.

Huvudsyftet med uppsatsen är att se hur ett företags annonsering om återköp av aktier påverkar dess börskurs i Sverige. Som delsyfte kommer även en undersökning göras om huruvida reaktionen skiljer sig mellan olika branscher samt om Sveriges reaktion skiljer sig från den tidigare forskningen i USA och i Storbritannien. Undersökningen har genomförts med hjälp av en eventstudie där den abnormala avkastningen beräknas. En intervju utförs för att bekräfta resultatet.Resultatet gav en sammanlagd kumulativ avkastning på 0,57 %. Det visade även att det finns en skillnad mellan olika branschers reaktion på en annonsering av ett återköp.

The purpose of this study is to examine the effects of joint venture announcements on stock prices behavior and simultaneously to test the German stock market (Frankfurter Wertpapierbörse) for efficiency. We tried not only to analyze the general impacts of a JV-announcement but also to look for differences in the market response to announcements of different types of joint ventures, namely: domestic, international, horizontal and vertical. Our expectations of efficient market were confirmed during our paper, which employed the technique of the standard event study. The calculation of abnormal returns which are the signals for market efficiency or inefficiency respectively were based on the market model, establishing linear relationship between the return on the market and the return on an individual security. The parameters of the model were obtained through regression analysis..

Tidigare forskning har indikerat att det kan existera informationsasymmetrier i aktiemarknaden mellan olika marknadsaktörer. Personer med insyn har oftast tillgång till särskild information som inte är tillgänglig för marknaden. Detta innebär att möjligheter till abnormala avkastningar existerar för dessa personer vid handel av bolagets finansiella instrument. Denna studie undersöker i första hand huruvida insynshandel på Aktietorget och Nordic Growth Market genererar abnormal avkastning samt om det föreligger en skillnad i resultat mellan dessa marknadsplatser. Det som ligger till grund för studien är insiders samtliga köp- och säljtransaktioner under 2005 för bolag noterade på Aktietorget och Nordic Growth Market.

Every day a large numbers of transactions occur by people with different backgrounds. Insiders? are a part of them and are considered to have an insight in companies that is not accessible to outsiders. This affects the market conditions for the participants when trading stocks, where individual participants regularly have the possibility to earn abnormal returns at the expense of others. Although Sweden, Germany and the United States continually keep developing the insider trading regulation, research shows that insiders? still have the ability to earn abnormal returns.
