Obesity increases the risk for several conditions, including type 2 diabetes mellitus, cardiovascular disease, hypertension, osteoarthirits and certain types of cancer. Twin- and family studies have shown that there is a major genetic component in the determination of body mass. In recent years several technological and scientific advance have been made in obesity research. For instance, novel replicated loci have been revealed by a number of genome wide association studies. This thesis aimed to investigate the association of genetic factors and obesity-related quantitative traits. The first study investigated the role of the lactase gene in anthropometric traits. We genetically defined lactose persistence by genotyping 31 720 individuals of European descent. We found that lactase persistence was significantly correlated with weight and body mass index but not with height. In the second study we performed the largest whole genome linkage scan for body mass index to date. The sample consisted of 4401 twin families and 10 535 individuals from six European countries. We found supporting evidence for two loci (3q29 and 7q36). We observed that the heritability estimate increased substantially when additional family members were removed from the analyses, which suggests reduced environmental variance in the twin sample. In the third study we assessed metabonomic, transcriptomic and genomic variation in a Finnish population cohort of 518 individuals. We formed gene expression networks to portray pathways and showed that a set of highly correlated genes of an inflammatory pathway associated with 80 serum metabolites (of 134 quantified measures). Strong association was found, for example, with several lipoprotein subclasses. We inferred causality by using genetic variation as anchors. The expression of the network genes was found to be dependent on the circulatory metabolite concentrations.

Kansainvälisen oikeuden alaan kuuluvassa tutkielmassa käsitellään humanitaarisen intervention oikeutusta ja laillisuutta. Tutkimuskysymyksenä on, missä määrin humanitaarisilla näkökohdilla perusteltuja sotilaallisia toimia tai niillä uhkaamista voi pitää kansainvälisoikeudellisesti hyväksyttävänä ja millainen painoarvo ennakkotapauksena olisi annettava NATO-maiden Kosovossa toteuttamalle väliintulolle. Tutkielmassa perehdytään ihmisoikeusajattelun tiettyjen taustaoletusten kritiikkiin. Tarkastelun kohteena ovat erityisesti kannanotot, joiden mukaan ihmisoikeuksia ei voi pitää luonteeltaan universaaleina, sekä kyseiseen kritiikkiin liittyvät väitteet siitä, että ns. hegemonisessa asemassa olevat valtiot hyödyntävät ihmisoikeusargumentteja oikeuttaakseen voimankäyttönsä. Universaalisuuskritiikkiä voidaan pitää pitkälti perusteltuna, mutta nykyinen kansainvälinen yhteisö tarvitsee kuitenkin tietynlaisia yleismaailmallisia normeja voidakseen toimia tehokkaasti. Kritiikin ei voikaan katsoa pätevän humanitaarisen intervention kannalta keskeisiin ihmisoikeusnormeihin kuten kansanmurhan kieltoon, sillä kyseiset velvoitteet suojaavat kansainvälisen yhteisön toimivuutta ja uskottavuutta. Humanitaarisiin argumentteihin liittyy kuitenkin muita ongelmia: niillä on esimerkiksi aika ajoin pyritty oikeuttamaan sotilaallisia toimia, joissa ihmisoikeusnäkökohdat eivät välttämättä ole olleet etusijalla. Ihmisoikeuksille ei ole syytä antaa kansainvälisessä oikeudessa asemaa universaaleina "superargumentteina", jotka eivät olisi kyseenalaistettavissa. YK:n peruskirjan ja kansainvälisen tapaoikeuden näkökulmasta humanitaarisen intervention kaltaiseen voimankäyttöön vaaditaan turvallisuusneuvoston hyväksyntä, jota ei Kosovo-operaatioon saatu. Interventiota voi tässä suhteessa pitää yksiselitteisesti laittomana, sillä sen tueksi esitetyt oikeudelliset argumentit eivät ole vakuuttavia. Tapaukseen liittyvät ihmisoikeusnäkökohdat ovat kuitenkin siinä määrin merkittäviä, että ongelmaan ei ole perusteltua suhtautua tiukan legalistisesti. Operaation hyväksyminen moraaliargumenttien nojalla voisi kuitenkin johtaa nykyisten voimankäyttörajoitusten marginalisoitumiseen, mikä olisi yllä käsitellyn kritiikin valossa ongelmallista. Tutkielmassa nostetaan suositeltavaksi ratkaisuksi lähestymistapa, jossa Kosovon tapaus ymmärretään yksittäisenä oikeudenvastaisena mutta samalla oikeudenulkoisena poikkeustapauksena. Tällöin peruskirjan mukainen voimankäytön sääntely säilyy entisellään ilman että humanitaariset näkökohdat jäisivät tyystin huomiotta. Ratkaisu ei sulje pois mahdollisuutta suhtautua positiivisesti Kosovo-operaation mahdollisesti luomaan "poliittiseen normiin": suuren mittakaavan ihmisoikeusloukkaukset eivät jää Euroopassa seurauksitta. Ilman turvallisuusneuvoston suostumusta toteutettaviin humanitaarisiin interventioihin liittyvien käytännöllisten ja kansainvälisoikeudellisten riskien vuoksi niihin on kuitenkin aihetta suhtautua suurella varauksella.

The purpose of this study is to analyse the development and understanding of the idea of consensus in bilateral dialogues among Anglicans, Lutherans and Roman Catholics. The source material consists of representative dialogue documents from the international, regional and national dialogues from the 1960s until 2006. In general, the dialogue documents argue for agreement/consensus based on commonality or compatibility. Each of the three dialogue processes has specific characteristics and formulates its argument in a unique way. The Lutheran-Roman Catholic dialogue has a particular interest in hermeneutical questions. In the early phases, the documents endeavoured to describe the interpretative principles that would allow the churches to together proclaim the Gospel and to identify the foundation on which the agreement in the church is based. This investigation ended up proposing a notion of basic consensus , which later developed into a form of consensus that seeks to embrace, not to dismiss differences (so-called differentiated consensus ). The Lutheran-Roman Catholic agreement is based on a perspectival understanding of doctrine. The Anglican-Roman Catholic dialogue emphasises the correctness of interpretations. The documents consciously look towards a common future , not the separated past. The dialogue s primary interpretative concept is koinonia. The texts develop a hermeneutics of authoritative teaching that has been described as the rule of communion . The Anglican-Lutheran dialogue is characterised by an instrumental understanding of doctrine. Doctrinal agreement is facilitated by the ideas of coherence, continuity and substantial emphasis in doctrine. The Anglican-Lutheran dialogue proposes a form of sufficient consensus that considers a wide set of doctrinal statements and liturgical practices to determine whether an agreement has been reached to the degree that, although not complete , is sufficient for concrete steps towards unity. Chapter V discusses the current challenges of consensus as an ecumenically viable concept. In this part, I argue that the acceptability of consensus as an ecumenical goal is based not only the understanding of the church but more importantly on the understanding of the nature and function of the doctrine. The understanding of doctrine has undergone significant changes during the time of the ecumenical dialogues. The major shift has been from a modern paradigm towards a postmodern paradigm. I conclude with proposals towards a way to construct a form of consensus that would survive philosophical criticism, would be theologically valid and ecumenically acceptable.

This thesis examines the right to self-determination which is a norm used for numerous purposes by multiple actors in the field of international relations, with relatively little clarity or agreement on the actual and potential meaning of the right. In international practice, however, the main focus in applying the right has been in the context of decolonization as set by the United Nations in its early decades. Thus, in Africa the right to self-determination has traditionally implied that the colonial territories, and particularly the populations within these territories, were to constitute the people who were entitled to the right. That is, self-determination by decolonization provided a framework for the construction of independent nation-states in Africa whilst other dimensions of the right remained largely or totally neglected. With the objective of assessing the scope, content, developments and interpretations of the right to self-determination in Africa, particularly with regard to the relevance of the right today, the thesis proceeds on two fundamental hypotheses. The first is that Mervyn Frost s theory of settled norms, among which he lists the right to self-determination, assumes too much. Even if the right to self-determination is a human right belonging to all peoples stipulated, inter alia, in the first Article of the 1966 International Human Rights Covenants, it is a highly politicized and context-bound right instead of being settled and observed in a way that its denial would need special justification. Still, the suggested inconsistency or non-compliance with the norm of self-determination is not intended to prove the uselessness or inappropriateness of the norm, but, on the contrary, to invite and encourage debate on the potential use and coverage of the right to self-determination. The second hypothesis is that within the concept of self-determination there are two normative dimensions. One is to do with the idea and practice of statehood, the nation and collectivity that may decide to conduct itself as an independent state. The other one is to do with self-determination as a human right, as a normative condition, to be enjoyed by people and peoples within states that supersedes state authority. These external and internal dimensions need to be seen as complementary and co-terminous, not as mutually exclusive alternatives. The thesis proceeds on the assumption that the internal dimension of the right, with human rights and democracy at its core, has not been considered as important as the external. In turn, this unbalanced and selective interpretation has managed to put the true normative purpose of the right making the world better and bringing more just polity models into a somewhat peculiar light. The right to self-determination in the African context is assessed through case studies of Western Sahara, Southern Sudan and Eritrea. The study asks what these cases say about the right to self-determination in Africa and what their lessons learnt could contribute to the understanding and relevance of the right in today s Africa. The study demonstrates that even in the context of decolonization, the application of the right to self-determination has been far from the consistent approach supposedly followed by the international community: in many respects similar colonial histories have easily led to rather different destinies. While Eritrea secured internationally recognized right to self-determination in the form of retroactive independence in 1993, international recognition of distinct Western Sahara and Southern Sudan entities is contingent on complex and problematic conditions being satisfied. Overall, it is a considerable challenge for international legality to meet empirical political reality in a meaningful way, so that the universal values attached to the norm of self-determination are not overlooked or compromised but rather reinforced in the process of implementing the right. Consequently, this thesis seeks a more comprehensive understanding of the right to self-determination with particular reference to post-colonial Africa and with an emphasis on the internal, human rights and democracy dimensions of the norm. It is considered that the right to self-determination cannot be perceived only as an inter-state issue as it is also very much an intra-state issue, including the possibility of different sub-state arrangements exercised under the right, for example, in the form of autonomy. At the same time, the option of independent statehood achieved through secession remains a mode of exercising and part of the right to self-determination. But in whatever form or way applied, the right to self-determination, as a normative instrument, should constitute and work as a norm that comprehensively brings more added value in terms of the objectives of human rights and democracy. From a normative perspective, a peoples right should not be allowed to transform and convert itself into a right of states. Finally, in light of the case studies of Western Sahara, Southern Sudan and Eritrea, the thesis suggests that our understanding of the right to self-determination should now reach beyond the post-colonial context in Africa. It appears that both the questions and answers to the most pertinent issues of self-determination in the cases studied must be increasingly sought within the postcolonial African state rather than solely in colonial history. In this vein, the right to self-determination can be seen not only as a tool for creating states but also as a way to transform the state itself from within. Any such genuinely post-colonial approach may imply a judicious reconsideration, adaptation or up-dating of the right and our understanding of it in order to render it meaningful in Africa today.

This report derives from the EU funded research project “Key Factors Influencing Economic Relationships and Communication in European Food Chains” (FOODCOMM). The research consortium consisted of the following organisations: University of Bonn (UNI BONN), Department of Agricultural and Food Marketing Research (overall project co-ordination); Institute of Agricultural Development in Central and Eastern Europe (IAMO), Department for Agricultural Markets, Marketing and World Agricultural Trade, Halle (Saale), Germany; University of Helsinki, Ruralia Institute Seinäjoki Unit, Finland; Scottish Agricultural College (SAC), Food Marketing Research Team - Land Economy Research Group, Edinburgh and Aberdeen; Ashtown Food Research Centre (AFRC), Teagasc, Food Marketing Unit, Dublin; Institute of Agricultural & Food Economics (IAFE), Department of Market Analysis and Food Processing, Warsaw and Government of Aragon, Center for Agro-Food Research and Technology (CITA), Zaragoza, Spain. The aim of the FOODCOMM project was to examine the role (prevalence, necessity and significance) of economic relationships in selected European food chains and to identify the economic, social and cultural factors which influence co-ordination within these chains. The research project considered meat and cereal commodities in six different European countries (Finland, Germany, Ireland, Poland, Spain, UK/Scotland) and was commissioned against a background of changing European food markets. The research project as a whole consisted of seven different work packages. This report presents the results of qualitative research conducted for work package 5 (WP5) in the pig meat and rye bread chains in Finland. Ruralia Institute would like to give special thanks for all the individuals and companies that kindly gave up their time to take part in the study. Their input has been invaluable to the project. The contribution of research assistant Sanna-Helena Rantala was significant in the data gathering. FOODCOMM project was coordinated by the University of Bonn, Department of Agricultural and Food Market Research. Special thanks especially to Professor Monika Hartmann for acting as the project leader of FOODCOMM.

The European Union (EU) is faced with a continuous decrease in public support. There is a tension between the growing Euroscepticism and the concurrent academic discourse of a shared European identity. Informed and inspired by the current debates, this Master’s Thesis investigates the potential of a shared past to create shared identity. It also addresses the logic of cultural exclusion that is often connected to collective cultural identities. The source material is a combination of exam essays, written as answers to the history tests in the Finnish matriculation examinations of 2005-2008, and upper secondary school history textbooks. From the sources, current perceptions of Islam (as Europe’s Other) and the age of imperialism (as a debated period from Europe’s past) among the youth are studied. Through the analysis the thesis aims to indicate the level of consensus within the pupils’ identification with the past and with Europe. This objective is pursued through examining the pupils’ perceptions of Europe’s past and its relationship to non-European cultures and countries as they are manifested in the essays, and reflecting upon the level of influence that history textbooks as representatives of national hegemonic historical narratives might have on the contents, framings and emphases with and through which the pupils approach, imagine, and reproduce Europe’s past. The approach is based on previous research on the presence of history and the field of textbook research. The theoretical categories with which the sources are analyzed are derived primarily from literature on identity, European integration, history and memory, postcolonial criticism, and theorizations of European identity. Results of the research project suggest that the rhetoric of European superiority, despite its apparent demise, still resonates in contemporary understandings of Europeanness. Dominant perceptions of imperialism comprise of European agency and colonial submission, dominant perceptions of the Islamic world of fundamental difference. Identification with European history among the Finnish youth is rather shallow when examined through perceptions of imperialism; the Islamic world is perceived as Other and its representations are dominated by recent and contemporary international relations.

Previous research has been inconclusive regarding the impact of those who invest in entrepreneurs. Consider for a moment how potentially important they are to entrepreneurs. They for example decide who deserves funding, how much time they contribute to their portfolio firms, how they grant entrepreneurs access to their networks, and help entrepreneurs acquire additional funding. In sum, investors potentially have a great impact on the success of entrepreneurs. It is therefore important that we better understand the environment, relationships and context in which parties operate. This thesis contains five articles that explore investors’ and entrepreneurs’ relationships from various viewpoints, in theoretical frameworks, and use a variety of data and research methods. The first article is a literature review that summarises what we know of venture capital, business angel and corporate venture capital funding. The second article studies the entrepreneurs’ investor selection process, its consequences, and identifies key factors that influence the process. Earlier, the common approach has been to concentrate research on the investors’ selection policy, not the entrepreneurs’. The data and conclusions are based on multiple case studies. The article analyses how entrepreneurs can ensure that they get the best possible investor, when it is possible for an entrepreneur to select an investor, and what are the consequences of investor selection. The third article employs power constructs (dependency, power balance/imbalance, power sources) and analyses their applicability in the investor-entrepreneur relationship. Power constructs are extensively studied and utilised in the management and organisation literature. In entrepreneur investor relationships, power aspects are rarely analysed. However, having the ability to “get others to do things they would not otherwise do” is a very common factor in the investor-entrepreneur relationship. Therefore, employing and analysing the applicability of power constructs in this setting is well founded. The article is based on a single case study but suggests that power constructs could be applicable and consequently provide additional insights into the investor-entrepreneur relationship. The fourth article studies the role of advisors in the venture capital investment process and analyses implications for research and practice, particularly from the entrepreneurs’ perspective. The common entrepreneurial finance literature describes the entrepreneur-investor relationship as linear and bilateral. However, it was discovered that advisors may influence the relationship. In this article, the role of advisors, operating procedures and advisors’ impact on different parties is analysed. The fifth article concentrates on investors’ certification effect. The article measures and demonstrates that venture capital investment is likely to increase the credibility (in terms of media attention) of early stage firms, those that most often need additional credibility. Understanding investor certification can affect how entrepreneurs evaluate investment offers and how investors can make their offers appear more lucrative.
