Environmental change and human history in the Jabal Harun area, Jordan

The research is related to the Finnish Jabal Harun Project (FJHP), which is part of the research unit directed by Professor Jaakko Frösén. The project consists of two interrelated parts: the excavation of a Byzantine monastery/pilgrimage centre on Jabal Harun, and a multiperiod archaeological survey of the surrounding landscape. It is generally held that the Near Eastern landscape has been modified by millennia of human habitation and activity. Past climatic changes and human activities could be expected to have significantly changed also the landscape of the Jabal Harun area. Therefore it was considered that a study of erosion in the Jabal Harun area could shed light on the environmental and human history of the area. It was hoped that it would be possible to connect the results of the sedimentological studies either to wider climatic changes in the Near East, or to archaeologically observable periods of human activity and land use. As evidence of some archaeological periods is completely missing from the Jabal Harun area, it was also of interest whether catastrophic erosion or unfavourable environmental change, caused either by natural forces or by human agency, could explain the gaps in the archaeological record. Changes in climate and/or land-use were expected to be reflected in the sedimentary record. The field research, carried out as part of the FJHP survey fieldwork, included the mapping of wadi terraces and cleaning of sediment profiles which were recorded and sampled for laboratory analyses of facies and lithology. To obtain a chronology for the sedimentation and erosion phases also OSL (optically stimulated luminescence) dating samples were collected. The results were compared to the record of the Near Eastern palaeoclimate, and to data from geoarchaeological studies in central and southern Jordan. The picture of the environmental development was then compared to the human history in the area, based on archaeological evidence from the FJHP survey and the published archaeological research in the Petra region, and the question of the relationship between human activity and environmental change was critically discussed. Using the palaeoclimatic data and the results from geoarchaeological studies it was possible to outline the environmental development in the Jabal Harun area from the Pleistocene to the present.It is appears that there was a phase of accumulation of sediment before the Middle Palaeolithic period, possibly related to tectonic movement. This phase was later followed by erosion, tentatively suggested to have taken place during the Upper Palaeolithic. A period of wadi aggradation probably occurred during the Late Glacial and continued until the end of the Pleistocene, followed by significant channel degradation, attributed to increased rainfall during the Early Holocene. It seems that during the later Holocene channel incision has been dominant in the Jabal Harûn area although there have been also small-scale channel aggradation phases, two of which were OSL-dated to around 4000-3000 BP and 2400-2000 BP. As there is no evidence of tectonic movements in the Jabal Harun area after the early Pleistocene, it is suggested that climate change and human activity have been the major causes of environmental change in the area. At a brief glance it seems that many of the changes in the settlement and land use in the Jabal Harun area can be explained by climatic and environmental conditions. However, the responses of human societies to environmental change are dependent on many factors. Therefore an evaluation of the significance of environmental, cultural, socio-economic and political factors is needed to decide whether certain phenomena are environmentally induced. Comparison with the wider Petra region is also needed to judge whether the phenomena are characteristic of the Jabal Harun area only, or can they be connected to social, political and economic development over a wider area.

Tohtoriksi tulemisen tarina

The study examines the dissertation process. The thesis is based on twenty-three autobiographical stories. They were collected from PhDs who had taken their doctoral degrees at the University of Helsinki. The purpose is to investigate the experiences of these PhD recipients and find out what they recall of the events, traditions, and meanings associated with their PhD studies. An anthology collected from PhDs in the historical sciences, which was published in 1998, was used as reference material. This study begins with a general presentation of the history and values of the university and the traditions of the academic community in Finland. Thereafter, the data and the methodological framework of the study are presented. Attention is paid to the discipline background, sex and age of these PhDs, which may have affected their storytelling. The former studies concerning the academic life together with the experiences of the writers revealed that the process of becoming a PhD graduate is generally considered as an academic rite of passage. The change from student status to becoming a fully accepted professional member of one’s field is real, transforming and at certain points, ritualized. The finding of an inner logic to the doctoral process, which included meaningful turning points, was central to the narrative analysis approach. During the process there were different kinds of struggles and highlights. The family background, university studies and time in employment had directed the doctoral studies of some PhD students enormously. But generally the most memorable and value laden were the phases of actually writing the dissertation, the public examination, and the celebration party in the evening called “karonkka”. The picture that emerged from these various life-stories demonstrated that there was no ivory tower where doctoral candidates live an isolated existence. Everyday cares in ordinary life and tasks in academic life are both demanding and rewarding at the same time. The main point is that the academic community in general and PhD supervisors in particular should concentrate not only on the thesis-writing process their students but also on the doctoral students´ wider life situation. Doctoral students need scientific, financial, and mental support. Somebody must be available to inspire and offer encouragement otherwise the process will be disturbed. The successful completion of the PhD ritual gives the PhD graduate self-confidence and respect but its’ influence on the doctors’ subsequent academic career is diverse. The dissertation process is a personal and unique experience. The aim of the PhD graduation is that this traditional ritual leads to a successful completion and ensures a positive reward for the PhD graduate and the academic community. Keywords: autobiography, narratives, academic traditions, PhD graduates.

From a "Student" to a Lifelong "Consumer" : Constructions of Educability in Adult Students' Narrative Life Histories

The focus of this study was to examine the constructions of the educable subject of the lifelong learning (LLL) narrative in the narrative life histories of adult students at general upper secondary school for adults (GUSSA). In this study lifelong learning has been defined as a cultural narrative on education, “a system of political thinking” that is not internally consistent, but has contradictory themes embedded within it (Billig et al., 1988). As earlier research has shown and this study also confirms, the LLL narrative creates differences between those who are included and those who fall behind and are excluded from the learning society ideal. Educability expresses socially constructed interpretations on who benefit from education and who should be educated and how. The presupposition in this study has been that contradictions between the LLL narrative and the so-called traditional constructions of educability are likely to be constructed as the former relies on the all-inclusive interpretation of educability and the latter on the meritocratic model of educating individuals based on their innate abilities. The school system continues to uphold the institutionalized ethos of educability that ranks students into the categories “bright”, “mediocre”, and “poor” (Räty & Snellman, 1998) on the basis of their abilities, including gender-related differences as well as differences based on social class. Traditional age-related norms also persist, for example general upper secondary education is normatively completed in youth and not in adulthood, and the formal learning context continues to outweigh both non-formal and informal learning. Moreover, in this study the construction of social differences in relation to educability and, thereafter unequal access to education has been examined in relation to age, social class, and gender. The biographical work of the research participants forms a peephole that permits the examination of the dilemmatic nature of the constructions of educability in this study. Formal general upper secondary education in adulthood is situated on the border between the traditional and the LLL narratives on educability: participation in GUSSA inevitably means that one’s ability and competence as a student and learner becomes reassessed through the assessment criteria maintained by schools, whereas according to the principles of LLL everyone is educable; everyone is encouraged to learn throughout their lives regardless of age, social class, or gender. This study is situated in the field of adult education, sociology of education, and social psychological research on educability, having also been informed by feminist studies. Moreover, this study contributes to narrative life history research combining the structural analysis of narratives (Labov & Waletzky, 1997), i.e. mini-stories within life history, with the analysis of the life histories as structural and thematic wholes and the creation of coherence in them; thus, permitting both micro and macro analyses. On accounting for the discontinuity created by participation in general upper secondary school study in adulthood and not normatively in youth, the GUSSA students construct coherence in relation to their ability and competence as students and learners. The seven case studies illuminate the social differences constructed in relation to educability, i.e. social class, gender, age, and the “new category of student and learner”. In the data of this study, i.e. 20 general upper secondary school adult graduates’ narrative life histories primarily generated through interviews, two main coherence patterns of the adult educable subject emerge. The first performance-oriented pattern displays qualities that are closely related to the principles of LLL. Contrary to the principles of lifewide learning, however, the documentation of one’s competence through formal qualifications outweighs non-formal and informal learning in preparation for future change and the competition for further education, professional careers, and higher social positions. The second flexible learning pattern calls into question the status of formal, especially theoretical and academically oriented education; inner development is seen as more important than such external signs of development — grades and certificates. Studying and learning is constructed as a hobby and as a means to a more satisfactory life as opposed to a socially and culturally valued serious occupation leading to further education and career development. Consequently, as a curious, active, and independent learner, this educable but not readily employable subject is pushed into the periphery of lifelong learning. These two coherence patterns of the adult educable subject illuminate who is to be educated and how. The educable and readily employable LLL subject is to participate in formal education in order to achieve qualifications for working life, whereas the educable but not employable subject may utilize lifewide learning for her/his own pleasure. Key words: adult education, general upper secondary school for adults, educability, lifelong learning, narrative life history

Early detection of type 2 diabetes mellitus in Chinese and Indian adult population

Objectives of this study were to determine secular trends of diabetes prevalence in China and develop simple risk assessment algorithms for screening individuals with high-risk for diabetes or with undiagnosed diabetes in Chinese and Indian adults. Two consecutive population based surveys in Chinese and a prospective study in Mauritian Indians were involved in this study. The Chinese surveys were conducted in randomly selected populations aged 20-74 years in 2001-2002 (n=14 592) and 35-74 years in 2006 (n=4416). A two-step screening strategy using fasting capillary plasma glucose (FCG) as first-line screening test followed by standard 2-hour 75g oral glucose tolerance tests (OGTTs) was applied to 12 436 individuals in 2001, while OGTTs were administrated to all participants together with FCG in 2006 and to 2156 subjects in 2002. In Mauritius, two consecutive population based surveys were conducted in Mauritian Indians aged 20-65 years in 1987 and 1992; 3094 Indians (1141 men), who were not diagnosed as diabetes at baseline, were reexamined with OGTTs in 1992 and/or 1998. Diabetes and pre-diabetes was defined following 2006 World Health Organization/ International Diabetes Federation Criteria. Age-standardized, as well as age- and sex-specific, prevalence of diabetes and pre-diabetes in adult Chinese was significantly increased from 12.2% and 15.4% in 2001 to 16.0% and 21.2% in 2006, respectively. A simple Chinese diabetes risk score was developed based on the data of Chinese survey 2001-2002 and validated in the population of survey 2006. The risk scores based on β coefficients derived from the final Logistic regression model ranged from 3 – 32. When the score was applied to the population of survey 2006, the area under operating characteristic curve (AUC) of the score for screening undiagnosed diabetes was 0.67 (95% CI, 0.65-0.70), which was lower than the AUC of FCG (0.76 [0.74-0.79]), but similar to that of HbA1c (0.68 [0.65-0.71]). At a cut-off point of 14, the sensitivity and specificity of the risk score in screening undiagnosed diabetes was 0.84 (0.81-0.88) and 0.40 (0.38-0.41). In Mauritian Indian, body mass index (BMI), waist girth, family history of diabetes (FH), and glucose was confirmed to be independent risk predictors for developing diabetes. Predicted probabilities for developing diabetes derived from a simple Cox regression model fitted with sex, FH, BMI and waist girth ranged from 0.05 to 0.64 in men and 0.03 to 0.49 in women. To predict the onset of diabetes, the AUC of the predicted probabilities was 0.62 (95% CI, 0.56-0.68) in men and 0.64(0.59-0.69) in women. At a cut-off point of 0.12, the sensitivity and specificity was 0.72(0.71-0.74) and 0.47(0.45-0.49) in men; and 0.77(0.75-0.78) and 0.50(0.48-0.52) in women, respectively. In conclusion, there was a rapid increase in prevalence of diabetes in Chinese adults from 2001 to 2006. The simple risk assessment algorithms based on age, obesity and family history of diabetes showed a moderate discrimination of diabetes from non-diabetes, which may be used as first line screening tool for diabetes and pre-diabetes, and for health promotion purpose in Chinese and Indians.

The effects of human induced disturbances on the sediment geochemistry of Baltic Sea embayments with a focus on eutrophication history

Historical sediment nutrient concentrations and heavy-metal distributions were studied in five embayments in the Gulf of Finland and an adjacent lake. The main objective of the study was to examine the response of these water bodies to temporal changes in human activities. Sediment cores were collected from the sites and dated using 210Pb and 137Cs. The cores were analyzed for total carbon (TC), total nitrogen (TN), total phosphorus (TP), organic phosphorus (OP), inorganic phosphorus (IP), biogenic silica (BSi), loss on ignition (LOI), grain size, Cu, Zn, Al, Fe, Mn, K, Ca, Mg and Na. Principal component analysis (PCA) was used to summarize the trends in the geochemical variables and to compare trends between the different sites. The links between the catchment land use and sediment geochemical data were studied using a multivariate technique of redundancy analysis (RDA). Human activities produce marked geochemical variations in coastal sediments. These variations and signals are often challenging to interpret due to various sedimentological and post-depositional factors affecting the sediment profiles. In general, the sites studied here show significant upcore increases in sedimentation rates, TP and TN concentrations. Also Cu, which is considered to be a good indicator of anthropogenic influence, showed clear increases from 1850 towards the top part of the cores. Based on the RDA-analysis, in the least disturbed embayments with high forest cover, the sediments are dominated by lithogenic indicators Fe, K, Al and Mg. In embayments close to urban settlement, the sediments have high Cu concentrations and a high sediment Fe/Mn ratio. This study suggests that sediment accumulation rates vary significantly from site to site and that the overall sedimentation can be linked to the geomorphology and basin bathymetry, which appear to be the major factors governing sedimentation rates; i.e. a high sediment accumulation rate is not characteristic either to urban or to rural sites. The geochemical trends are strongly site specific and depend on the local geochemical background, basin characteristics and anthropogenic metal and nutrient loading. Of the studied geochemical indicators, OP shows the least monotonic trends in all studied sites. When compared to other available data, OP seems to be the most reliable geochemical indicator describing the trophic development of the study sites, whereas Cu and Zn appear to be good indicators for anthropogenic influence. As sedimentation environments, estuarine and marine sites are more complex than lacustrine basins with multiple sources of sediment input and more energetic conditions in the former. The crucial differences between lacustrine and estuarine/coastal sedimentation environments are mostly related to Fe. P sedimentation is largely governed by Fe redox-reactions in estuarine environments. In freshwaters, presence of Fe is clearly linked to the sedimentation of other lithogenic metals, and therefore P sedimentation and preservation has a more direct linkage to organic matter sedimentation.

"Politiikka on kirkossa" : Keskustapuolueen kirkkopoliittisten tavoitteiden muotoutuminen vuosina 1966–1978

This study in church history deals with the formation of aims in the church politics of the Centre Party during a period of extensive politicisation in Finnish society – 1966 to 1978. The focus is on the processes of creating political input within the party organisation. The most important source material consists of the records of the highest party organs as well as material from the party office and the party’s committee for church politics. In the late 1960s, at a time of leftist radicalism in Finnish society, issues concerning the Church were seldom dealt with in the highest party organs, even though informal discussion took place within the party. This phase was followed by a conservative reaction in society during the 1970s. The rightist trend as well as the ongoing politicisation process substantially strengthened the role of church politics in the party. An aim of great importance was to prevent those supporters who belonged to the Lutheran revival movements from moving into the Finnish Christian League. Therefore it became increasingly important to prove that the Centre Party was defending the Church as well as so-called Christian values in state politics, e.g., by advocating religious instruction in schools. The Centre Party also defended the independence and legal status of the Church, at the same time positioning itself against Finland’s Social Democratic Party. Many party members were of the opinion that the church politics should have been about defending the Church and Christian values in state politics instead of defending the proportional share of the party’s seats in the ecclesiastical decision-making system. Nevertheless, the struggle for hegemony between the Centre Party and the Social Democrats was reflected in the Evangelical Lutheran Church particularly since 1973. Thus the aims of church politics were increasingly directed towards ecclesiastical elections and appointments in the 1970s. To justify its activities in church elections, the party stressed that it was not politicising the Church. To the contrary, it was asserted that the church leaders themselves had politicised the Church by favouring the Social Democrats. These alleged efforts to affiliate the Church with one political party were strictly condemned in the Centre Party. But when it came to the political parties’ activity in church elections, opinions diverged. Generally, the issues of church politics resembled those of the party’s trade union politics in the 1970s.

Rukous on perintöä suvusta sukuun : Ikääntyneet ja uskonto vuosituhannen vaihteen Suomessa

"Prayer, a heritage from generation to generation" The elderly and religion in Finland at the turn of the 21st century The strong demographic changes in Europe mean that research on the elderly is highly needed, and also from the viewpoint of their resources and opportunities. Further, it is important to determine, how the elderly could find a meaningful place as members of the chain of generations in our rapidly changing society. The aim of this study was to find out how the elderly build and perceive their place in the society through religious texts. The study was based on religious texts written by elderly people in the study groups of the Finnish pensioners organization Pension Union (Eläkeliitto). These 943 short prayers, poems, and aphorisms were collected during the Tree of Life (Elämänpuu) project in 1998-1999 and were then analysed applying qualitative content analysis and grounded theory methodology. The social construction of aging and the view of communication as a collective signifying process were used as the mainstays of the research perspective. The themes brought forward by the elderly writers were grouped around three key themes: the self, the world and religion. In this examination religion with its forms of expression appeared to be deeply rooted to each of these themes and thus seems a vital part of the elderly writers' culture. In connection with the theme of the self, the religious forms of expression provided a means of building a coherent and culturally accepted self-image which is further supported by positive views of personal history and current life situation. In relation to the world theme, the elderly writers stressed the importance of close social relationships and at the same time expressed anxiety with regard to the changing world. Concerning the theme of religion, the religious forms of expression were first and foremost used in building and creating a sense of personal safety and a belief in the future. The study suggests that skill in the use of religious language enable the elderly to cope with equivocal life events and cognitive dissonance. At the social level the religious forms of expression seemed to connect the writers to the Finnish linguistic culture and identity, as well as to the collective memory, where religion plays a central part. By using religious language the elderly both exploit and maintain these considerable social resources. The key result of the study is that the elderly were found to have a significant and separate role in the continuity and well-being of society. Bound to the religious tradition, the elderly seem to carry significant information as regards the identity of the Finnish people, information which is essentially passed on to future generations. By sustaining traditions and thus the collective identity, they perform a uniquely productive task and their life experience could be seen as a particular type of capital in the society. This result also raises a grave question: Will the elderly of the future be able to undertake this task that so profoundly requires religious literacy?

Kaukana Vatikaanista – Katolinen kirkko Suomessa 1989–1998

Tutkimuksessa tarkastellaan katolista kirkkoa Suomessa vuosina 1989-1998. Tutkimus alkaa paavi Johannes Paavali II:n Pohjoismaiden-vierailusta kesällä 1989 ja päättyy Suomen katolisen kirkon pitkäaikaisen piispan Paul Verschurenin eroon tehtävästään vuonna 1998. Tutkimuksen kolme pääkysymystä ovat kirkon hallinnon ja rakenteen muutokset, katolisen kirkon identiteetti Suomessa ja ekumeeniset suhteet erityisesti Suomen evankelis-luterilaiseen kirkkoon. Lähteinä olen käyttänyt Helsingin katolisen hiippakunnan lehteä Fidesiä, muuta lehdistömateriaalia ja haastatteluja. Paavin-vierailulla oli merkittävät seuraukset niin Suomen katoliselle paikalliskirkolle kuin luterilaiselle kirkollekin. Vierailun myötä pieni katolinen vähemmistö tuli tunnetummaksi Suomessa. Vierailu muutti Vatikaanin käsityksiä Suomesta, millä oli kauaskantoiset vaikutukset kirkkojen ekumeenisiin suhteisiin. Pyhän Birgitan 600-vuotismuistojuhlien yhteydessä Suomen ja Ruotsin luterilaisten ja katolisten piispojen yhdessä paavin kanssa toimittama jumalanpalvelus, paavin ekumeniaa käsitellyt kiertokirje Ut unum sint ja Pohjoismaiden luterilaisten ja katolisten kirkkojen aloittamat neuvottelut kirkko- ja virkakäsityksistä olivat 1990-luvun merkittäviä ekumeenisia hetkiä, joihin paavin vierailulla oli vaikutusta. Kirkon hallinto ja rakenne olivat monelta osin jo vakiintuneet 1990-luvulle tultaessa, mutta muutamia merkittäviä muutoksia tapahtui. Kirkon jäsenmäärä kasvoi lähinnä maahanmuuton johdosta koko tutkitun ajanjakson ajan. Jäsenmäärän kasvu synnytti uusia seurakuntia ja kappeleita hiippakuntaan. Halu kappelin rakentamiseen ei aina kuitenkaan lähtenyt hiippakunnan tarpeesta vaan yksittäisten ihmisten tai liikkeiden. Esimerkiksi neokatekumenaalinen maallikkoliike rakennutti 1990-luvun alussa Ouluun kappelin, mutta hiippakunta ei ollut täysin hankkeen takana. Ongelmat kappeleiden rakentamisessa ja monet muutkin haasteet, johtuivat pitkälti kirkon taloudellisesta tilanteesta. Kirkolla ei ollut verotusoikeutta eikä jäsenten maksamat avustukset riittäneet kattamaan kuluja. Katolinen kirkko yritti 1990-luvun alkupuolella miettiä keinoja taloudellisen tilanteen parantamiseksi. Piispa Verschuren piti monessa yhteydessä myös esillä vähemmistöjen juridista asemaa koskevia ongelmia ja uskontolainsäädännön epäkohtia. Kolmas merkittävä rakenteellinen muutos kirkossa oli papiston puolalaistuminen. Katolisen kirkon identiteettiä Suomessa on vaikea erottaa omaksi kokonaisuudekseen koskien vain 1990-lukua. Olenkin pyrkinyt tarkastelemaan identiteettiä niistä haasteista käsin, joita kirkko 1990-luvulla kohtasi. Suomessa käytiin keskustelua muun muassa eronneiden tilanteesta ja naisen asemasta. Kirkko kannusti jäseniään keskusteluun ja myös piispa ja papisto olivat usein toivottujen uudistusten kannalla. Suomessa katolinen kirkko eli pienenä vähemmistönä, joten monet kirkon oppiin liittyvät kysymykset olivat haasteellisia. Esimerkiksi perhe- ja seksuaalieettiset kysymykset ja naisen asema olivat vaikeita tilanteessa, jossa suurin osa katolilaisista oli naimisissa ei-katolilaisen kanssa. Vaikka Suomessakin toivottiin muutoksia, joihinkin kirkon oppiin liittyviin kysymyksiin, Keski-Euroopasta alkanut protestiliikehdintä kirkon uudistumiseksi ei näkynyt täällä voimakkaasti. Suomessa kirkon tilanne oli hyvin erilainen kuin niissä Euroopan maissa, joissa liikehdintä sai kannatusta. Suomessa arvostettiin kirkon perinteistä liturgiaa ja pyrittiin rakentamaan yhtenäistä, identiteetiltään suomalaista katolista kirkkoa.

Towards a Critique of the Concept of the Right to Self-Determination in Africa : A Conceptual Examination and the Cases of Western Sahara, Southern Sudan and Eritrea

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.

Reinventing Nordic Openness : Transparency and State Information in Finland

The study explores new ideational changes in the information strategy of the Finnish state between 1998 and 2007, after a juncture in Finnish governing in the early 1990s. The study scrutinizes the economic reframing of institutional openness in Finland that comes with significant and often unintended institutional consequences of transparency. Most notably, the constitutional principle of publicity (julkisuusperiaate), a Nordic institutional peculiarity allowing public access to state information, is now becoming an instrument of economic performance and accountability through results. Finland has a long institutional history in the publicity of government information, acknowledged by law since 1951. Nevertheless, access to government information became a policy concern in the mid-1990s, involving a historical narrative of openness as a Nordic tradition of Finnish governing Nordic openness (pohjoismainen avoimuus). International interest in transparency of governance has also marked an opening for institutional re-descriptions in Nordic context. The essential added value, or contradictory term, that transparency has on the Finnish conceptualisation of governing is the innovation that public acts of governing can be economically efficient. This is most apparent in the new attempts at providing standardised information on government and expressing it in numbers. In Finland, the publicity of government information has been a concept of democratic connotations, but new internationally diffusing ideas of performance and national economic competitiveness are discussed under the notion of transparency and its peer concepts openness and public (sector) information, which are also newcomers to Finnish vocabulary of governing. The above concepts often conflict with one another, paving the way to unintended consequences for the reforms conducted in their name. Moreover, the study argues that the policy concerns over openness and public sector information are linked to the new drive for transparency. Drawing on theories of new institutionalism, political economy, and conceptual history, the study argues for a reinvention of Nordic openness in two senses. First, in referring to institutional history, the policy discourse of Nordic openness discovers an administrative tradition in response to new dilemmas of public governance. Moreover, this normatively appealing discourse also legitimizes the new ideational changes. Second, a former mechanism of democratic accountability is being reframed with market and performance ideas, mostly originating from the sphere of transnational governance and governance indices. Mobilizing different research techniques and data (public documents of the Finnish government and international organizations, some 30 interviews of Finnish civil servants, and statistical time series), the study asks how the above ideational changes have been possible, pointing to the importance of nationalistically appealing historical narratives and normative concepts of governing. Concerning institutional developments, the study analyses the ideational changes in central steering mechanisms (political, normative and financial steering) and the introduction of budget transparency and performance management in two cases: census data (Population Register Centre) and foreign political information (Ministry for Foreign Affairs). The new policy domain of governance indices is also explored as a type of transparency. The study further asks what institutional transformations are to be observed in the above cases and in the accountability system. The study concludes that while the information rights of citizens have been reinforced and recalibrated during the period under scrutiny, there has also been a conversion of institutional practices towards economic performance. As the discourse of Nordic openness has been rather unquestioned, the new internationally circulating ideas of transparency and the knowledge economy have entered this discourse without public notice. Since the mid 1990s, state registry data has been perceived as an exploitable economic resource in Finland and in the EU public sector information. This is a parallel development to the new drive for budget transparency in organisations as vital to the state as the Population Register Centre, which has led to marketization of census data in Finland, an international exceptionality. In the Finnish Ministry for Foreign Affairs, the post-Cold War rhetorical shift from secrecy to performance-driven openness marked a conversion in institutional practices that now see information services with high regards. But this has not necessarily led to the increased publicity of foreign political information. In this context, openness is also defined as sharing information with select actors, as a trust based non-public activity, deemed necessary amid the global economic competition. Regarding accountability system, deliberation and performance now overlap, making it increasingly difficult to identify to whom and for what the public administration is accountable. These evolving institutional practices are characterised by unintended consequences and paradoxes. History is a paradoxical component in the above institutional change, as long-term institutional developments now justify short-term reforms.

Climate forcing on avian life history

In the 21st century, human-induced global climate change has been highlighted as one of the most serious threats to ecosystems worldwide. According to global climate scenarios, the mean temperature in Finland is expected to increase by 1.8 4.0°C by the end of the century. The regional and seasonal change in temperature has predicted to be spatially and temporally asymmetric, where the High-Arctic and Antarctic areas and winter and spring seasons have been projected to face the highest temperature increase. To understand how species respond to the ongoing climate change, we need to study how climate affects species in different phases of their life cycle. The impact of climate on breeding and migration of eight large-sized bird species was studied in this thesis, taking food availability into account. The findings show that climatic variables have considerable impact on the life-history traits of large-sized birds in northern Europe. The magnitude of climatic effects on migration and breeding was comparable with that of food supply, conventionally regarded as the main factor affecting these life-history traits. Based on the results of this thesis and the current climate scenarios, the following not mutually exclusive responses are possible in the near future. Firstly, asymmetric climate change may result in a mistiming of breeding because mild winters and early spring may lead to earlier breeding, whereas offspring are hatching into colder conditions which elevate mortality. Secondly, climate induced responses can differ between species with different breeding tactics (income vs. capital breeding), so that especially capital breeders can gain advantage on global warming as they can sustain higher energy resources. Thirdly, increasing precipitation has the potential to reduce the breeding success of many species by exposing nestlings to more severe post-hatching conditions and hampering the hunting conditions of parents. Fourthly, decreasing ice cover and earlier ice-break in the Baltic Sea will allow earlier spring migration in waterfowl. In eiders, this can potentially lead to more productive breeding. Fifthly, warming temperatures can favour parents preparing for breeding and increase nestling survival. Lastly, the climate-induced phenological changes in life history events will likely continue. Furthermore, interactions between climate and food resources can be complex and interact with each other. Eiders provide an illustrative example of this complexity, being caught in the crossfire between more benign ice conditions and lower salinity negatively affecting their prime food resource. The general conclusion is that climate is controlling not only the phenology of the species but also their reproductive output, thus affecting the entire population dynamics.

Short-term effects of variable retention on epigaeic spiders and carabid beetles in Finland

Forestry has influenced forest dwelling organisms for centuries in Fennoscandia. For example, in Finland ca. 30% of the threatened species are threatened because of forestry. Nowadays forest management recommendations include practices aimed at maintaining biodiversity in harvesting, such as green-tree retention. However, the effects of these practices have been little studied. In variable retention, different numbers of trees are retained, varying from green-tree retention (at least a few live standing trees in clear-cuts) to thinning (only individual trees removed). I examined the responses of ground-dwelling spiders and carabid beetles to green-tree retention (with small and large tree groups), gap felling and thinning aimed at an uneven age structure of trees. The impacts of these harvesting methods were compared to those of clear-cutting and uncut controls. I aimed to test the hypothesis that retaining more trees positively affects populations of those species of spiders and carabids that were present before harvesting. The data come from two studies. First, spiders were collected with pitfall traps in south-central Finland in 1995 (pre-treatment) and 1998 (after-treatment) in order to examine the effects of clear-cutting, green-tree retention (with 0.01-0.02-ha sized tree groups), gap felling (with three 0.16-ha sized openings in a 1-ha stand), thinning aiming at an uneven age structure of trees and uncut control. Second, spiders and carabids were caught with pitfall traps in eastern Finland in 1998-2001 (pre-treatment and three post-treatment years) in eleven 0.09-0.55-ha sized retention-tree groups and clear-cuts adjacent to them. Original spider and carabid assemblages were better maintained after harvests that retained more trees. Thinning maintained forest spiders well. However, gap felling and large retention-tree groups maintained some forest spider and carabid species in the short-term, but negatively affected some species over time. However, use of small retention-tree groups was associated with negative effects on forest spider populations. Studies are needed on the long-term effects of variable retention on terrestrial invertebrates; especially those directed at defining appropriate retention patch size and on the importance of structural diversity provided by variable retention for invertebrate populations. However, the aims of variable retention should be specified first. For example, are retention-tree groups planned to constitute life-boats , stepping-stones or to create structural diversity? Does it suffice that some species are maintained, or do we want to preserve the most sensitive ones, and how are these best defined? Moreover, the ecological benefits and economic costs of modified logging methods should be compared to other approaches aimed at maintaining biodiversity.
