The aim of the study was to examine if the benthos in a restored portion of a small lowland stream south of Linkoping differed from two non restored reference areas two years after restoration. The reference areas were one stretch downstream and one upstream stretches of the restored stream. The benthic invertebrates were collected using standardized kick sampling. In order to classify the communities and estimate any differences, three different indices were exercised. In addition rank-abundance curves and checklists were used to get a picture of species composition.

Då mängden information bara ökar, så ökar även behovet att ha åtkomst till informationen lättillgängligt. Detta skapar då ett behov för ett gränssnitt som kan söka bland informationen. I detta arbete har det undersökts om en implementation av Vector Space Model ger mera relevanta resultat jämfört mot en enklare implementation som inte baseras på Vector Space Model. Sökningen utförs i en relationsdatabas med ett inverterat index, databasen fylls med data ifrån internetforumet Stack Overflow. Genom att bygga en sökmotor som returnerade två olika resultatlistor för varje sökning så fick tio användare testa och utvärdera resultatens relevans.

Handel med derivat har ökat explosionsartat på den svenska marknaden de senaste åren med möjligheter att handla i derivat med ett stort antal olika underliggande tillgångar. Denna utveckling har dock inte skapat möjligheten att handla derivat med utvecklingen på den svenska fastighetsmarknaden som underliggande tillgång.Möjligheterna att idag få fastighetsexponering utan att direkt äga fastigheter är begränsade och har låg korrelation med utvecklingen på den svenska fastighetsmarknaden. Ett ämne som har diskuterats flitigt innan fastighetskrisen 2007 är möjligheten att handla derivat med den svenska fastighetsmarknaden som underliggande tillgång. Problemet har varit att det inte funnits ett tillförlitligt index som man kan använda för att prissätta derivatet. Nya typer av index har utvecklats de senaste åren och därmed skapat en möjlighet att introducera fastighetsderivat som produkt på den svenska marknaden.För att kunna handla med fastighetsderivat krävs att en del förutsättningar uppnås däribland likviditet, ett fungerande underliggande index, en osymmetrisk marknad och en aktör som agerar som någon typ av återförsäljare av produkten det vill säga någon som erbjuder handel i fastighetsderivat.

Objective: The papers objective is to create a deeper understanding for whether or not cultural and psychic distance affects corporate establishments in the EU.Method: The results have been gathered through intense data collection through interviews with ScaniaAB and Business Sweden. There has also been extensive research of 36 different companies and their first establishments in different countries. We have then analyzed the results through cultural and psychic distance and through Uppsala University's internationalization process model.Conclusion: The conclusions of this paper are:Corporate establishment often occurs in neighboring countries because of the similarity to the domestic markets which contribute with a greater security.Since the introduction of the EU single market, corporate establishments have become easier within the single market.The cultural and psychic distance does exist within the EU, however the internal market decreases these distances and the impact on corporate establishments.The market commitment is essential to the corporates survival within the new market.Cultural and psychic distance affects small firms more often since their lack of network and experience.Cultural and psychic distances are two different but related phenomena..

It is important, for companies operating on a homogeneous product market, to understand and adapt to customer needs. Since coffee is a homogeneous product in food retail it is vital for coffee companies to work extensively with differentiation and the fierce competition. The prevailing homogenity makes it difficult for companies to develop the product itself and must therefore work to create added value to the product.The purpose of this thesis is to carry out a study on consumer decision-making when purchasing homogeneous products, and to examine how companies work to strengthen their brand and gain market share in a homogeneous product market. The market that this thesis highlights is the coffee market.To answer the purpose of this thesis the writers have conducted a questionnaire survey regarding consumers? decision-making process and interviewed two marketing managers for two major actors on the coffee market.

A trading halt is a measure conducted by a securities exchange in order to reduce information imbalances between market participants, thus enabling a higher level of market efficiency. A market is said to be efficient when new information concerning a company is instantly reflected in its stock price, implying that abnormal stock returns cannot be systematically achieved in an efficient market. The purpose of this study is to examine the occurrence of abnormal stock returns following trading halts on the Stockholm Stock Exchange. The study is based on a sample of 64 trading halts executed between January 2003 and February 2008. Historical daily prices for stocks subject to trading halts during the period have been gathered from the Datastream Advance database, while information on date and time of trading halts have been collected from the Stockholm Stock Exchange website.

China has the world?s largest population and during the last thirty years the country has implemented political and economical changes that have affected China to move towards a more western market economic direction. At first this development was going slow but during the last five years it has increased which today has made China the world?s greatest growing economy. China?s improved cooperation with the world is one reason for this growth which has led to a cumulative of the consumer market.

Rysslandsfonder är en av många fonder som finns tillgängliga för att investera i. Ryssland har haft en starkutveckling de senaste åren. I uppsatsen görs en jämförelse av utveckling och risk mellan Rysslandsfonder och den svenska markanden representerad av SIX Return index. Utvecklingen hos Rysslandsfonderna har månadsvis under perioden 1999-2005 varit betydligt mer gynnsam än för det representerade Sverige index. Risken med standardavvikelse som en indikator för detta visar att det innebär en större risk att investera i Rysslandsfonder.

The change in the information society has affected the development of the labour market for information specialists and informants as well as their roles. Companies are now aware of the fact that information specialists have a variety of important skills and competence that is important for them. The goal of this thesis is to see what defines an information specialist and an informant and also to find out their situation on the labour market. The similarities and differences between the two professions will also be discussed in the thesis. The main method used is the investigation of the job advertisements in the journal DIK-forum from the year 2000 and year 2004.

The construction market has, as a result of the crisis in Europe been uncertain in recent years. During the year 2013, the construction will be stabilized, in particular Finland. The geographical proximity between Sweden and Finland and similarities in cultures and climates makes Finland a coveted market for many Swedish companies.Differences in national regulations and guidelines, which are produced by the authorities in different countries, are examples of barriers that may hamper the process, including for Swedish villa suppliers, to establish themselves on the Finnish market. It may be useful when facing a new export drive, to look up what similarities and differences there are between the countries building codes, to prevent mistakes and unnecessary costs to the project work..

The aim with this thesis came out of a strong interest for Passage Retrieval. Our intention has not been to evaluate an IR-system. Instead our goal has been to analyze the result of indexing documents and their passages. We have been studying the weights of the different terms in the different indices, in comparison with other parameters like frequency, normalized frequency and the inversed document frequency. Further more we have been looking at how the weights are spread using for instance the standard deviation.

The Swedish system of rent control has recieved a lot of critique for creating an ill-functioning housing market. Supporters however claim that a movement towards market rents would lead to increased segregation. We evaluate whether rent control has managed to counteract segregation in Stockholm. Our evaluation is based on a data set of 292 representative households in Stockholm. We find that residents in rent controlled apartments in attractive locations typically are born in Sweden by Swedish parents and that they are likely to have a higher income than residents in rent controlled apartments in less attractive locations.

After the formation of the European Union internal market in 1992, member state specific obstacles and barriers were largely removed. This was especially the case in harmonised industries where standardisation and technical regulation have led to legal certainty. Despite this, a large range of trade regulation continues to remain distortional to trade, in addition to the ongoing tariffs and subsidies. The key trade regulations relate to a number of areas involving technical regulations such as production labelling and the protection of intellectual property rights. Whilst policy makers claim justification based around the need to correct market failure in delivering desired outcomes, the question is whether these regulations are appropriate responses to market failures or if they have simply been imposed in an attempt to protect domestic markets.

 I uppsatsen undersöks effektiviteten av de tre nordiska aktieindexterminerna OMXS30, OBX och OMXC20 vars underliggande index representerar den svenska, norska respektive den danska aktiemarknaden. Analysen baseras på den svaga formen av den effektiva marknadshypotesen och den närbesläktade random walk hypotesen. Aktieindexterminerna undersöks under perioden januari 1997 till december 2008 samt under perioder då den nordiska marknaden karaktäriseras av bull och bear perioder. Testresultaten av Augmented Dickey-Fuller (ADF) samt Kwiatkowski, Phillips, Schmidt och Shin (KPSS) testet tyder på att aktieindexterminerna följer en random walk och att nordiska aktieindexterminer är effektiva under den undersökta perioden. Då testen utförs för de kortare bull och bear perioderna erhålls motsägelsefulla resultat vilket medför att slutsatser om huruvida aktieindexterminerna är effektiva under dessa perioder ej kan dras. .

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.
