Tolerance of Noise as a Necessity of Urban Life. Noise pollution as an environmental problem and its cultural perceptions in the city of Helsinki This study looks at the noise pollution problem and the change in the urban soundscape in the city of Helsinki during the period from the 1950s to the present day. The study investigates the formation of noise problems, the politicization of the noise pollution problem, noise-related civic activism, the development of environmental policies on noise, and the expectations that urban dwellers have had concerning their everyday soundscape. Both so-called street noise and the noise caused by, e.g., neighbors are taken into account. The study investigates whether our society contains or has for some time contained cultural and other elements that place noise pollution as an essential or normal state of affairs as part of urban life. It is also discussed whether we are moving towards an artificial soundscape, meaning that the auditory reality, the soundscape, is more and more under human control. The concept of an artificial soundscape was used to crystallize the significance of human actions and the role of modern technology in shaping soundscapes and also to link the changes in the modern soundscape to the economic, political, and social changes connected to the modernization process. It was argued that the critical period defining noise pollution as an environmental problem were the years from the end of the 1960s to the early 1970s. It seems that the massive increase of noise pollution caused by road traffic and the introduction of the utopian traffic plans was the key point that launched the moral protest against the increase of noise pollution, and in general, against the basic structures and mindsets of society, including attitudes towards nature. The study argues that after noise pollution was politicized and institutionalized, the urban soundscape gradually became the target of systematic interventions. However, for various reasons, such as the inconsistency in decision making, our increased capacity to shape the soundscape has not resulted in a healthy or pleasant urban soundscape. In fact the number of people exposed to noise pollution is increasing. It is argued that our society contains cultural and other elements that urge us to see noise as a normal part of urban life. It is also argued that the possibility of experiencing natural, silent soundscapes seems to be the yardstick against which citizens of Helsinki have measured how successful we are in designing the (artificial) soundscape and if the actions of noise control have been effective. This work discusses whose interests it serves when we are asked to accept noise pollution as a normal state of affairs. It is also suggested that the quality of the artificial soundscape ought to be radically politicized, which might give all citizens a better and more equal chance to express their needs and wishes concerning the urban soudscape, and also to decide how it ought to be designed.

This dissertation examines the short- and long-run impacts of timber prices and other factors affecting NIPF owners' timber harvesting and timber stocking decisions. The utility-based Faustmann model provides testable hypotheses of the exogenous variables retained in the timber supply analysis. The timber stock function, derived from a two-period biomass harvesting model, is estimated using a two-step GMM estimator based on balanced panel data from 1983 to 1991. Timber supply functions are estimated using a Tobit model adjusted for heteroscedasticity and nonnormality of errors based on panel data from 1994 to 1998. Results show that if specification analysis of the Tobit model is ignored, inconsistency and biasedness can have a marked effect on parameter estimates. The empirical results show that owner's age is the single most important factor determining timber stock; timber price is the single most important factor in harvesting decision. The results of the timber supply estimations can be interpreted using utility-based Faustmann model of a forest owner who values a growing timber in situ.

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.

Prolyl oligopeptidase (POP, prolyl endopeptidase, EC 3.4.21.26) is a serine-type peptidase (family S9 of clan SC) hydrolyzing peptides shorter than 30 amino acids. POP has been found in various mammalian and bacterial sources and it is widely distributed throughout different organisms. In human and rat, POP enzyme activity has been detected in most tissues, with the highest activity found mostly in the brain. POP has gained scientific interest as being involved in the hydrolyzis of many bioactive peptides connected with learning and memory functions, and also with neurodegenerative disorders. In drug or lesion induced amnesia models and in aged rodents, POP inhibitors have been able to revert memory loss. POP may have a fuction in IP3 signaling and it may be a possible target of mood stabilizing substances. POP may also have a role in protein trafficking, sorting and secretion. The role of POP during ontogeny has not yet been resolved. POP enzyme activity and expression have shown fluctuation during development. Specially high enzyme activities have been measured in the brain during early development. Reduced neuronal proliferation and differentation in presence of POP inhibitor have been reported. Nuclear POP has been observed in proliferating peripheral tissues and in cell cultures at the early stage of development. Also, POP coding mRNA is abundantly expressed during brain ontogeny and the highest levels of expression are associated with proliferative germinal matrices. This observation indicates a special role for POP in the regulation of neurogenesis during development. For the experimental part, the study was undertaken to investigate the expression and distribution of POP protein and enzymatic activity of POP in developing rat brain (from embryonic day 14 to post natal day 7) using immunohistochemistry, POP enzyme activity measurements and western blot-analysis. The aim was also to find in vivo confirmation of the nuclear colocalization of POP during early brain ontogeny. For immunohistochemistry, cryosections from the brains of the fetuses/rats were made and stained using specific antibody for POP and fluorescent markers for POP and nuclei. The enzyme activity assay was based on the fluorescence of 7- amino-4-methylcoumarin (AMC) generated from the fluorogenic substrate succinyl-glycyl-prolyl-7-amino-4-methylcoumarin (Suc-Gly-Pro-AMC) by POP. The amounts of POP protein and the specifity of POP antibody in rat embryos was confirmed by western blot analysis. We observed that enzymatic activity of POP is highest at embryonic day 18 while the protein amounts reach their peak at birth. POP was widely present throughout the developmental stages from embryonic day 14 to parturition day, although the POP-immunoreactivity varied abundantly. At embryonic days 14 and 18 notably amounts of POP was distributed at proliferative germinal zones. Furthermore, POP was located in the nucleus early in the development but is transferred to cytosol before birth. At P0 and P7 the POP-immunoreactivity was also widely observed, but the amount of POP was notably reduced at P7. POP was present in cytosol and in intercellular space, but no nuclear POP was observed. These findings support the idea of POP being involved in specific brain functions, such as neuronal proliferation and differentation. Our results in vivo confirm the previous cell culture results supporting the role of POP in neurogenesis. Moreover, an inconsistency of POP protein amounts and enzymatic activity late in the development suggests a strong regulation of POP activity and a possible non-hydrolytic role at that stage.

ABSTRACT The author Zacharias Topelius as a religious educator The present study concerns the author Zacharias Topelius (1818-98) as a religious educator. The study´s main questions are as follows: What is the theological and pedagogical content of Topelius books and how is his religious instruction linked with the history of his time. The primary sources are his educational books Naturens bok (The Book of the Nature, 1856), Boken om vårt land (The Book of our Land, 1875) and Evangelium för Barnen (Gospel for Children, 1893), as well as his storybooks Läsning för barn I-VIII (Reading for Children I-VIII, 1865-96). The dissertation concerns the his-tory of religious education. Its primary method is background-based systematic analy-sis. In Topelius children s books the view of God is characterised both as an omnipresent spirit and as Providence, who guides world history according to his plan. In addition to Lutheranism this view is also influenced by Nationalism and Romanticism. The theological content of the books emphasises instruction in Christian life that is natural to normative children s books. Topelius strongly expresses the importance of a personal relationship to God, an idealistic Christian view of one s fellow man and of one s own nation as well as the value of nature conservation. The books of Topelius were some of the first educational works on nature preservation in Finland. The didactic quality of Topelius children s books was high for 19th century Finland. Their main emphasis in terms of educational goals is on civilisation (Bildung), self-awareness, national solidarity and living idealism. The pedagogical argumentation is mostly based on theological, historical, social and rational reasoning. The primary principles in Topelius teaching are Christian nationalism, idealistic harmony and the agrarian bourgeois. Christian nationalism is the main element of Topelius religious education. He considers the fatherland as a God-given project and the taking care of it as a part of holy service. Idealistic harmony is seen as the comprehensive development of one s character in the sense of romantic idealism. The agrarian bourgeois principle combines the Finnish peasant tradition with the values of 19th century modern bourgeois culture. I have named Topelius vision of religious education the Christian national project of civilisation (Bildung). Its main theses are home, religion and fatherland. The author himself strongly believed in this vision and never questioned it despite its national chauvinism and theological inconsistency. The religious ideology represented in Topelius educational works and storybooks was popular among pedagogues during the whole era of the Finnish folk school. It fit per-fectly with the Christian national discourse stemming from 19th century ideological ten-dencies. Due to their appropriate content combined with their practical language and pedagogical methods, the books were popular both at school and in the home for a long period of time. Therefore the books of Topelius aptly symbolise the religious education of their time and manifest their author s pedagogical talent as a national religious educator and as a populariser of Christian nationalism. Topelius books have had a lasting influence on Finnish religiosity. Key words: Topelius, theology, religion, education, nationalism and national project

The benefits and drawbacks of homogeneity and heterogeneity have been debated at length. Whereas some researchers assert that heterogeneity is beneficial for groups that are engaged in complex problem solving, the other researchers emphasize the potential costs associated with diversity. The inconsistency is a result of the incomplete measurement of diversity and focus one or two types of diversity. Most research concentrates on the readily detected/visible characteristics, making the assumption that such characteristics are related to underlying attributes (e.g., attitudes and values). In many cases, the demographic characteristics do not covary perfectly with the psychological attributes. Thus both types of attributes need to be utilized to fully understand the impact of diversity. The present research with four essays takes into account both types of attributes and tests their impact on social integration in cross-cultural settings. The results indicate that: (1) readily detectable- and underlying attributes are not related; (2) diversity has overall a negative impact on social integration; (3) socio-cultural context potentially influences the salience of diversity; and (4) diversity and social integration influences the formation of social cognition in form of transactive memory directories. The limits of research and managerial implications are discussed.

Research on unit cohesion has shown positive correlations between cohesion and valued outcomes such as strong performance, reduced stress, less indiscipline, and high re-enlistment intentions. However, the correlations have varied in strength and significance. The purpose of this study is to show that taking into consideration the multi-component nature of cohesion and relating the most applicable components to specific outcomes could resolve much of the inconsistency. Unit cohesion is understood as a process of social integration among members of a primary group with its leaders, and with the larger secondary groups of which they are a part. Correspondingly, included in the framework are four bonding components: horizontal (peer) and vertical (subordinate and leader) and organizational and institutional, respectively. The data were collected as part of a larger research project on cohesion, leadership, and personal adjustment to the military. In all, 1,534 conscripts responded to four questionnaires during their service in 2001-2002. In addition, sociometric questionnaires were given to 537 group members in 47 squads toward the end of their service. The results showed that platoons with strong primary-group cohesion differed from other platoons in terms of performance, training quality, secondary-group experiences, and attitudes toward refresher training. On the sociometric level it was found that soldiers who were chosen as friends by others were more likely to have higher expected performance, better performance ratings, more positive attitudes toward military service, higher levels of well-being during conscript service, and fewer exemptions from duty during it. On the group level, the selection of the respondents own group leader rather than naming a leader from outside (i.e., leader bonding) had a bearing not only on cohesion and performance, but also on the social, attitudinal, and behavioral criteria. Overall, the aim of the study was to contribute to the research on cohesion by introducing a model that takes into account the primary foci of bonding and their impact. The results imply that primary-group and secondary-group bonding processes are equally influential in explaining individual and group performance, whereas the secondary-group bonding components are far superior in explaining career intentions, personal growth, avoidance of duty, and attitudes toward refresher training and national defense. This should be considered in the planning and conducting of training. The main conclusion is that the different types of cohesion components have a unique, positive, significant, but varying impact on a wide range of criteria, confirming the need to match the components with the specific criteria.
