The underlying cause of many human autoimmune diseases is unknown, but several environmental factors are implicated in triggering the self-destructive immune reactions. Multiple Sclerosis (MS) is a chronic autoimmune disease of the central nervous system, potentially leading to persistent neurological deterioration. The cause of MS is not known, and apart from immunomodulatory treatments there is no cure. In the early phase of the disease, relapsing-remitting MS (RR-MS) is characterized by unpredictable exacerbations of the neurological symptoms called relapses, which can occur at different intervals ranging from 4 weeks to several years. Microbial infections are known to be able to trigger MS relapses, and the patients are instructed to avoid all factors that might increase the risk of infections and to properly use antibiotics as well as to take care of dental hygiene. Among those environmental factors which are known to increase susceptibility to infections, high ambient air inhalable particulate matter levels affect all people within a geographical region. During the period of interest in this thesis, the occurrence of MS relapses could be effectively reduced by injections of interferon, which has immunomodulatory and antiviral properties. In this thesis, ecological and epidemiological analyses were used to study the possible connection between MS relapse occurrence, population level viral infections and air quality factors, as well as the effects of interferon medication. Hospital archive data were collected retrospectively from 1986-2001, a period in time ranging from when interferon medication first became available until just before other disease-modifying MS therapies arrived on the market. The grouped data were studied with logistic regression and intervention analysis, and individual patient data with survival analysis. Interferons proved to be effective in the treatment of MS in this observational study, as the amount of MS exacerbations was lower during interferon use as compared to the time before interferon treatment. A statistically significant temporal relationship between MS relapses and inhalable particular matter (PM10) concentrations was found in this study, which implies that MS patients are affected by the exposure to PM10. Interferon probably protected against the effect of PM10, because a significant increase in the risk of exacerbations was only observed in MS patients without interferon medication following environmental exposure to population level specific viral infections and PM10. Apart from being antiviral, interferon could thus also attenuate the enhancement of immune reactions caused by ambient air PM10. The retrospective approach utilizing carefully constructed hospital records proved to be an economical and reliable source of MS disease information for statistical analyses.

Purpose The aim of this thesis1 is to analyse theoretically how institutionalisation of competitive tendering2, governance and budgetary policies cannot be taken for granted to lead to accountability among institutional actors3. The nature of an institutionalised management accounting policy, its relevance as a source of power in organisational decision making, and in negotiating inter-organisational relationships, are also analysed. Practical motivation The practical motivation of the thesis is to show how practitioners and policy makers can institutionalise changes which improve the power of management accounting and control systems4 as a mechanism of accountability among institutional actors and in negotiating relationships with other organisations. Theoretical motivation and conceptual approach The theoretical motivation of the thesis is to extend the institutional framework of management accounting change proposed by Burns and Scapens (2000) by using the theories of critical realism, communicative action, negotiated order and the framework of circuits of power. The Burns and Scapens framework needs further theorisation to analyse the relationship between the institutionalisation of management accounting and accountability; and the relevance of management accounting information in negotiating in inter-organisational relationships. Methodology and field studies Field research took place in public and not-for-profit health care organisations and a municipality in Finland from 2008 to 2013. Data were gathered by document analysis, interviews, participation in meetings and observations. Findings The findings are explained in four different essays that show that institutionalisation of competitive tendering, governance and budgetary policies cannot be taken for granted to lead to accountability among institutional actors. The ways by which institutional actors think and act can be influenced by other institutional mechanisms, such as inter-organisational circuits of power and intraorganisational governance policies, independent of the institutional change process. The relevance of institutionalised management accounting policies in negotiating relationships between two or more organisations depends on processes and contexts through which institutional actors use management accounting information as a tool of communication, mutual understanding and power. Research limitations / implications The theoretical framework used can be applied validly in other studies. The empirical findings cannot be generalised directly to other organisations than the organisations analysed. Practical implications Competitive tendering and budgetary policies can be institutionalised to shape actions of institutional actors within an organisation. To lead to accountability, practitioners and policy makers should implement governance policies that increase the use of management accounting information in institutional actors’ thinking, actions and responsibility for their actions. To reach a negotiated order between organisations, institutionalised management accounting policies should be used as one of the tools of communication aiming to reach mutual agreement among institutional actors.

Tämän eksploratiivisen tutkimuksen tarkoituksena on tutkia yrittäjän persoonallisuuden roolia ekologisesti suuntautuneen brändin identiteetin ja assosiaatioiden rakentamisessa. Tutkimus on tehty yrittäjän näkökulmasta, jonka kontekstina ovat pienet ja keskisuuret yritykset. Tämä tutkimus pyrkii laajentamaan ja saamaan ymmärrystä keskeisistä käsitteistä, ja samalla edistämään PK-yrityksiin liittyvää kirjallisuutta. Tämän lisäksi tutkimus tarkastelee mitä assosiaatioita ekologisesti suuntautunut brändi korostaa identiteetissään. Tutkimus suoritettiin tapaustutkimuksena. Laadullista primääridataa kerättiin teemahaastattelemalla yrittäjää, havainnoimalla yhtä case-yrityksen messuosastoa, sekä keräämällä yrittäjän persoonallisuusattribuutteja. Jotta tutkimus saavuttaisi myös datan triangulaation, sekundääristä dataa kerättiin vahvistamaan aiempaa tutkimusta. Yhtenä sekundäärilähteenä toimivat kaksi artikkelia, jotka auttoivat vahvistamaan aiemmin esiin nostetut yrittäjän persoonallisuusattribuutit. Persoonallisuusattribuutteja verrattiin case-yrityksen brändin identiteettiin, jotta yrittäjän persoonallisuuden rooli brändin identiteetin rakentamisessa saataisiin selville. Tulokset osoittivat yhteyden brändin identiteetin ja yrittäjän persoonallisuuden välillä ekologisesti suuntautuneessa case-yrityksessä. Tulokset paljastivat myös joitakin yleisiä assosiaatioita joita luodaan ja vahvistetaan brändin identiteetin eri osa-alueiden avulla.

Tutkielman aiheena on EU:n kilpailuoikeudellinen lähestymistapa challenge-lausekkeisiin teknologinsiirtosopimuksia koskevassa ryhmäpoikkeusasetuksessa. Teknologian lisensoinnin katsotaan olevan tärkeä väline teknologian kehityksen levittämisessä ja innovaation edistämisessä. Joissakin tapauksissa lisenssisopimus voi sisältää kilpailua rajoittavia lausekkeita, joiden voidaan kuitenkin nähdä hyödyttävän kilpailua kokonaisuutta arvostellen. Tällaisia lausekkeita ovat niin sanotut ”no-challenge” – lauseke, eli sopimusehto, jonka nojalla lisenssinsaaja sitoutuu olemaan haastamatta lisensoidun immateriaalioikeuden pätevyyttä ja ”termination-on-challenge” – lauseke, joka antaa lisensoijalle haastettaessa oikeuden päättää lisenssisopimus. Tutkielmassa perehdytään challenge -lausekkeiden hyväksyttävyyden arviointiin Euroopan unionin kilpailuoikeuden näkökulmasta uuden 1.5.2014 voimaan tulleen ryhmäpoikkeusasetuksen valossa. Muissa kuin yksinoikeuksia luovissa teknologiansiirtosopimuksissa olevat termination-on-challenge – lausekkeita tulee uusimmassa ryhmäpoikkeusetuksessa aina perustua yritysten itse suorittamaan tapauskohtaiseen arviointiin. No-challenge – lausekkeet ovat jatkossakin aiemman käytännön mukaisesti ryhmäpoikkeuksen soveltamisalan ulkopuolella. Komission on perustellut challenge - lausekkeiden jättämistä asetuksen ulkopuolelle julkisella intressillä, joka on päästä eroon mitättömistä immateriaalioikeuksista. Komission on katsonut, että challenge – lausekkeiden kilpailua rajoittava ominaisuus on mitättömien immateriaalioikeuksien esiintyminen markkinoilla, mikä osaltaan vääristää kilpailua ja hidastaa toimijoiden markkinoille pääsyä. Toisaalta lausekkeiden voidaan sanoa edistävän kilpailua, sillä ne usein tarjoavat immateriaalioikeuden haltijalle riittävän oikeussuojan ja kannustimen lisensoida teknologia, mikä lisää kilpailua, keksijöiden kannustimia panostaa innovaatioihin sekä vähentää transaktiokustannuksia. Tutkielman keskeinen tulos on ennen kaikkea challenge-lausekkeiden kilpailuvaikutusten tunnistamisessa ja komission perusteluiden kriittisessä arvioinnissa. Komission linjauksen perustelut eivät saa riittävää tukea ottaen huomioon vaikutustenarvioinnin, EU:n tuomioistuinkäytännön sekä taloustieteellisen lähestymistavan. Tutkielman tulosten pohjalta ja tukeutuen eri oikeuslähteisiin, taloustieteellisiin argumentteihin ja oikeusvertailevaan tutkimukseen, on mahdollista tehdä johtopäätöksiä niistä seikoista ja argumenteista, joilla on merkitystä uuden politiikkalinjauksen kilpailuvaikutuksiin.

This thesis is the Logistics Development Forum's assignment and the work dealing with the development of the Port of Helsinki as part of Helsinki hub. The Forum aims to develop logistics efficiency through public-private co-operation and development of the port is clearly dependent on both factors. Freight volumes in the Port of Helsinki are the biggest single factor in hub and, therefore, the role of the port of the entire hub development is strong. The aim is to look at how the port will develop as a result of changes in the foreign trade of Finland and the Northern European logistics trends in 25 years time period. Work includes the current state analysis and scenario work. The analyses are intended to find out, which trends are the most important in the port volume development. The change and effect of trends is examined through scenarios based on current state. Based on the work, the structure of Finnish export industry and international demand are in the key role in the port volume development. There is significant difference between demands of Finnish exporting products in different export markets and the development between the markets has different impacts on the port volumes by mass and cargo type. On the other hand, the Finnish economy is stuck in a prolonged recession and competition between ports has become a significant factor in the individual port's volume development. Ecological valuesand regulations have changed the competitive landscape and maritime transport emissions reductions has become an important competitive factor for short routes in the Baltic Sea, such as in the link between Helsinki and Tallinn.

Under EU competition law, parent companies may be held jointly and severally liable for the competition law infringements committed by their subsidiaries. The possibility of holding parent companies liable demonstrates a significant exception from the idea of separate legal entities. However, it is not the only deviation developed under EU competition law. In cases, where the legal entity responsible for the anti-competitive conduct has changed its form, liability can be attributed to the new operator, in particular, to its successor. The principles of legal certainty and legitimate expectations are issues that surround the doctrines of parental and successor liability. The aim of this thesis is to present a comprehensive comparative analysis of the parental and successor liability doctrines and to clarify the conditions under which it is possible to attribute liability for the infringements of EU competition law. The main purpose is therefore to demonstrate the problems related to the allocation of liability and to discuss whether these liability principles, established to assure the effective enforcement of the EU competition rules, are good solutions. The research methods used in this thesis are the legal dogmatic approach and the comparative law approach. The former enables the possibility of using the case law and legislation as a framework in which the difficulties concerning the application of parental and successor liability can be discussed while the latter ensures the comparison of the characteristics and judgments. The doctrines of parental and successor liability are both well established, but the application practice has caused several difficulties. These problems derive from, inter alia, the broadness and disjointed developed of the doctrines. There has been much recent case law dealing with these issues and having the potential to open up a considerable risk and to allocate strict liability for parent and successor companies.

Our surrounding landscape is in a constantly dynamic state, but recently the rate of changes and their effects on the environment have considerably increased. In terms of the impact on nature, this development has not been entirely positive, but has rather caused a decline in valuable species, habitats, and general biodiversity. Regardless of recognizing the problem and its high importance, plans and actions of how to stop the detrimental development are largely lacking. This partly originates from a lack of genuine will, but is also due to difficulties in detecting many valuable landscape components and their consequent neglect. To support knowledge extraction, various digital environmental data sources may be of substantial help, but only if all the relevant background factors are known and the data is processed in a suitable way. This dissertation concentrates on detecting ecologically valuable landscape components by using geospatial data sources, and applies this knowledge to support spatial planning and management activities. In other words, the focus is on observing regionally valuable species, habitats, and biotopes with GIS and remote sensing data, using suitable methods for their analysis. Primary emphasis is given to the hemiboreal vegetation zone and the drastic decline in its semi-natural grasslands, which were created by a long trajectory of traditional grazing and management activities. However, the applied perspective is largely methodological, and allows for the application of the obtained results in various contexts. Models based on statistical dependencies and correlations of multiple variables, which are able to extract desired properties from a large mass of initial data, are emphasized in the dissertation. In addition, the papers included combine several data sets from different sources and dates together, with the aim of detecting a wider range of environmental characteristics, as well as pointing out their temporal dynamics. The results of the dissertation emphasise the multidimensionality and dynamics of landscapes, which need to be understood in order to be able to recognise their ecologically valuable components. This not only requires knowledge about the emergence of these components and an understanding of the used data, but also the need to focus the observations on minute details that are able to indicate the existence of fragmented and partly overlapping landscape targets. In addition, this pinpoints the fact that most of the existing classifications are too generalised as such to provide all the required details, but they can be utilized at various steps along a longer processing chain. The dissertation also emphases the importance of landscape history as an important factor, which both creates and preserves ecological values, and which sets an essential standpoint for understanding the present landscape characteristics. The obtained results are significant both in terms of preserving semi-natural grasslands, as well as general methodological development, giving support to science-based framework in order to evaluate ecological values and guide spatial planning.
