Kaupungin savut ja käryt : Helsingin ilmansuojelu 1945-1982

The smoke and fumes of the city: Air protection in Helsinki from 1945 to 1982 This dissertation examines air pollution and air protection in post-war Helsinki. The period studied ends in 1982 when the Air Protection Act entered into force, thus institutionalising air protection in Finland as a socially governed environmental matter. The dissertation is based on the research traditions of environmental politics and urban environmental history. The development of air protection is approached from the perspectives of politicisation and institutionalisation. The dissertation also investigates how air pollution grew into a social issue and presents various discursive ways of analysing air pollution and protection. The primary research material consists of municipal documents and newspapers, while supplementary material includes journal articles and interviews. The event history of air protection is described through an analysis of the material, including source criticism. The social ways of dealing with air pollution and the emergence of air protection are analysed in the light of case-specific air quality disputes from both factual and discursive perspectives. This approach enables the contextualisation of the development of air protection as part of the local history of post-war Helsinki. The dissertation presents the major sources of air pollution in Helsinki and describes the deterioration of air quality in a society which emphasised the primacy of economic prosperity. The air issue emerged during the 1950s in neighbourhood disputes and was exacerbated into a larger problem in the late 1960s. Concurrent to the formation of the field of environmental protection in Finland, an air protection organisation was established in the 1970s in Helsinki. As a result, air protection became a regular part of municipal government. Air protection in Helsinki developed from small-scale policies focused on individual cases into a large, institutionalised air protection system managed by experts. The dissertation research material gave rise to the following major research themes: the economic dimension of the air issue, the role of science in the formation of the environmental problem, and the establishment of norms for acceptable air quality and reasonable limits to air pollution in the urban environment. The paper also discusses the inequitable distribution of the negative effects of air pollution between the residents of different districts. The dissertation concludes that air protection in Helsinki became a local success story although it was long marred by inefficiency and partial failure.

Herrana metsässä : Kansatieteellinen tutkimus metsänhoitajuudesta

The aim of the research is to interpret the professional culture of Finnish university-educated foresters in historical perspective. The main material of this research consists of biographical interviews, altogether 226 life stories of Finnish foresters, as well as foresters private photograph collections and articles in forest students' magazines. This study is the first published Ph. D. dissertation of a large oral history project "Forestry Professions in a Changing Society" 1999 2002 collected by The Finnish Forest History Society, the University of Helsinki (Ethnology) and The Finnish Forest Museum Lusto. The forester education was organized in the Evo Forest Institute 1862 1908, at the University of Helsinki since 1908 and additionally at the University of Joensuu since 1982. At first all the vacancies were in the service of the Board of Forestry, but during the 20th century the working opportunities of foresters significantly expanded, even outside the traditional areas of forestry or abroad. At the same time the whole area of Finnish forestry had integrated more versatile values concerning the forests and their use. The male-dominated profession gained its first female members already in the 1920s, and the number of female students rose gradually from the 1970s onwards. In the 1990s almost half of the new forest students were women. The content of both work and education of Finnish forest professionals has faced huge changes during the 19th and 20th centuries. Despite this however, there has been a long-term vision of a firm profession based on joint experiences, shared memories and the common task of foresters in the Finnish forestry. The feeling of togetherness the forester spirit which was created in a tight-knit student group which kept in touch also later as professionals was needed to make the work possible. Through foresters' own attitudes and narratives of themselves, the study is focused on forest professionalism as a cultural process of successive generations of foresters. How have foresters socialized themselves into their profession? How has forest professionalism been maintained? What is the meaning of joint experiences and shared memories in the profession? By studying the manifestations of a culture it is possible to interpret the culture itself. There seems to be an astounding consensus of opinion concerning forest professionalism in the oral, visual and written stories of foresters. Even if all the individuals and some separate groups, such as female foresters and the younger generation of foresters, did not always share the same experiences, the vision of forest professionalism was collectively recognized and often even approved. The shared idea of "a real forest professionalism" is like a model narrative, a point of comparison, which is needed while looking for one s own professional identity.

The Development of the Concept of Music Education in Estonian Kindergartens, 1905-2008 : a Historical–Critical Overview

The dissertation focuses on the development of music education in Estonian kindergartens and the factors influencing it, analysed in the historical perspective relying on post-positivist paradigm. The study is based on the factors and subjects’ views on kindergarten music education from 1905 to 2008, recorded in written sources or ascertained by means of questionnaire and interview. The dissertation deals with music’s functions, music education in retrospective, factors influencing child’s musical aptitude and development and teacher’s role in it through the prism of history. The formation of Estonian kindergarten music education and the phenomenon of its development have been researched by stages: the first manifestations of music in kindergarten in 1905 - 1940; the formation of the concept of music education in 1941 - 1967 and the application of a unified system in 1968 - 1990. The work also outlines innovative trends in music education at the end of the last millennium and the beginning of this century, in 1991 - 2008. The study relies on a combined design and an analysis of historical archival material and empirical data. The empirical part of the study is based on the questionnaire (n=183) and interviews (n=18) carried out with kindergarten music teachers. The data has been analysed using both qualitative and quantitative methods. The subject of the research is the content and activity types of kindergarten music education and the role of music teacher in their implementation. The study confirmed that fundamental changes took place in Estonian kindergarten music education due to the change in political power in the 1940s. Following the example of the Soviet system of education, music in kindergarten became an independent music educational orientation and the position of a professionally trained music teacher was established (1947). It was also confirmed that in the newly independent Estonian Republic under the influence of innovative trends a new paradigm of music education arose from the traditional singing-centred education towards the more balanced use of music activity types (attaching importance to the child-centred approach, an increase in the number and variety of activity types). The most important conclusions made in the dissertation are that there has been improvement and development deriving from contemporary trends in the clear concept that has evolved in Estonian kindergarten music education over a century; professionally trained music teachers have had a crucial role in shaping it; and kindergarten music education is firmly positioned as a part of preschool education in Estonian system of education. Key words: early childhood music education, history of music education, kindergarten music education, early childhood music teachers

Erityisopetus muutoksen kynnyksellä - tilastollinen kuvaus erityisopetusjärjestelmästä ja sen määrällisestä kehityksestä 1970-luvun lopulta vuoteen 2008

The number of Finnish pupils attending special education has increased for more than a decade (Tilastokeskus 1999, 2000, 2001, 2003, 2004, 2005a, 2006b, 2007b, 2008b, 2008e, 2009b; Virtanen ja Ratilainen 1996). In the year 2007 nearly third of Finnish comprehensive school pupils took part in special needs education. According to the latest statistics, in the autumn of 2008 approximately 47 000 pupils have been admitted or transferred to special education and approximately 126 000 pupils received part-time special education during the 2007 - 2008 academic year. (Tilastokeskus 2008b, 2009b.) The Finnish special education system is currently under review. The Reform, both in legislation and in practice, began nationwide in the year 2008 (e.g. Special education strategy document, November 2007 and the development project Kelpo). The aim of the study was the statistical description of the Finnish special education system and on the other hand to gain a deeper understanding about the Finnish special education system and its quantitative increase, by analysis based on the nationwide statistical information. Earlier studies have shown that the growth in special education is affected by multiple independent variables and cannot be solely explained by the pupil characteristics. The statistical overview and analysis have been carried out in two parts. In the first part, the description and analysis were based on statistical time series from the academic year 1979 -1980 until 2008. While, in the second, more detailed description and analysis, based on comparable time series from 1995 to 2008 and from 2001-2002 to 2007-2008, is presented. Historical perspective was one part of this study. There was an attempt to find reasons explaining the observed growth in the special needs education from late 1960s to 2008. The majority of the research was based on the nationwide statistics information. In addition to this, materials including educational legislation literature, different kind of records of special education and preceding studies were also used to support the research. The main results of the study, are two statistical descriptions and time series analysis of the quantitative increase of the special needs education. Further, a summary of the plausible factors behind the special education system change and its quantitative increase, is presented. The conclusions coming from the study can be summarised as follows: the comparable statistical time series analysis suggests that the growth in special education after the year 1999 could be a consequence of the changes in the structure of special education and that new group of pupils have been directed to special needs education.

Coffee and risk of type 2 diabetes

Type 2 diabetes is one of the diseases that largely determined by lifestyle factors. Coffee is one of the most consumed beverages in the world and recently released data suggest the effects of coffee consumption on type 2 diabetes. The objective of the present study was to evaluate the effects of habitual coffee consumption on various aspects of type 2 diabetes and its most common complications. This study is part of the national FINRISK studies. Baseline surveys were carried out between 1972 and 1997. The surveys covered two eastern regions in 1972 and 1977, but were expanded to include a third region in southwestern Finland in 1982, 1987, 1992, and 1997. The Helsinki capital area was included in the survey in 1992 and 1997 and the Oulu province, in northern Finland, in 1997. Each survey was drawn from an independent random sample of the national register of subjects aged 25-64. In 1997, an additional sample of subjects aged 65-74 was conducted. The blood pressure, weight, and height of subjects were measured. By using self-administered questionnaires data were collected on medical history, socioeconomic factors, physical activity, smoking habits, and alcohol, coffee, and tea consumption. Higher coffee consumption was associated with higher body mass index, occupational physical activity and cigarette smoking, and lower blood pressure, education level, leisure time physical activity, tea consumption and alcohol use. Age, body mass index, systolic blood pressure and current smoking were positively associated with the risk of type 2 diabetes, however, education, and occupational, commuting and leisure time physical activity were inversely associated. The significant inverse association between coffee consumption and the risk of type 2 diabetes was found in both sexes but the association was stronger in women. Coffee consumption was significantly and inversely associated with fasting glucose, 2-hour plasma glucose, fasting insulin, impaired fasting glucose, impaired glucose regulation, and hyperinsulinemia among both men and women and with isolated impaired glucose tolerance among women. Serum gamma-glutamyltransferase modified the association between coffee consumption and incident diabetes. Among subjects with high serum -glutamyltransferase (>75th percentile), coffee consumption showed an inverse association for women, as well as men and women combined. An inverse association also occurred between coffee consumption and the risk of total, cardiovascular disease, and coronary heart disease mortality among patients with type 2 diabetes. The results of this study showed that habitual coffee consumption may be associated with a reduced risk of type 2 diabetes. Coffee consumption may have some effects on several markers of glycemia, and may lower the incident of type 2 diabetes in high normal serum -glutamyltransferase levels. Total, cardiovascular disease, and coronary heart disease mortality rate among subjects with type 2 diabetes may also be reduced by coffee consumption.

Construing and Defining the Out of Control : Addiction in the Media 1968-2008.

The four scientific articles comprising this doctoral dissertation offer new information on the presentation and construction of addiction in the mass media during the period 1968 - 2008. Diachronic surveys as well as quantitative and qualitative content analyses were undertaken to discern trends during the period in question and to investigate underlying conceptions of the problems in contemporary media presentations. The research material for the first three articles consists of a sample of 200 texts from Finland s biggest daily newspaper, Helsingin Sanomat, from the period 1968 - 2006. The fourth study examines English-language tabloid material published on the Internet in 2005 - 2008. A number of principal trends are identified. In addition to a significant increase in addiction reporting over time, the study shows that an internalisation of addiction problems took place in the media presentations under study. The phenomenon is portrayed and tackled from within the problems themselves, often from the viewpoint of the individuals concerned. The tone becomes more personal, and technical and detailed accounts are more and more frequent. Secondly, the concept of addiction is broadened. This can be dated to the 1990s. The concept undergoes a conventionalisation: it is used more frequently in a manner that is not thought to require explanation. The word riippuvuus (the closest equivalent to addiction in Finnish) was adopted more commonly in the reporting at the same time, in the 1990s. Thirdly, the results highlight individual self-governance as a superordinate principle in contemporary descriptions of addiction. If the principal demarcation in earlier texts was between us and them , it is now focused primarily on the individual s competence and ability to govern the self, to restrain and master one's behaviour. Finally, in the fourth study investigating textual constructions of female celebrities (Amy Winehouse, Britney Spears and Kate Moss) in Internet tabloids, various relations and functions of addiction problems, intoxication, body and gender were observed to function as cultural symbols. Addiction becomes a sign, or a style, that represents different significations in relation to the main characters in the tabloid stories. Tabloids, as a genre, play an important role by introducing other images of the problems than those featured in mainstream media. The study is positioned within the framework of modernity theory and its views on the need for self-reflexivity and biographies as tools for the creation and definition of the self. Traditional institutions such as the church, occupation, family etc. no longer play an important role in self-definition. This circumstance creates a need for a culture conveying stories of success and failure in relation to which the individual can position their own behaviour and life content. I propose that addiction , as a theme in media reporting, resolves the conflict that emanates from the ambivalence between the accessibility and the individualisation of consumer society, on the one hand, and the problematic behavioural patterns (addictions) that they may induce, on the other.

Inhomogeneity of asteroid 2008 TC3 (Almahata Sitta meteorites) revealed through magnetic susceptibility measurements

Magnetic susceptibility measurements were performed on freshly fallen Almahata Sitta meteorites. Most recovered samples are polymict ureilites. Those found in the first four months since impact, before the meteorites were exposed to rain, have a magnetic susceptibility in the narrow range of 4.92 ± 0.08 log 10-9 Am2/kg close to the range of other ureilite falls 4.95 ± 0.14 log 10-9 Am2/kg reported by Rochette et al. (2009). The Almahata Sitta samples collected one year after the fall have similar values (4.90 ± 0.06 log 10-9 Am2/kg), revealing that the effect of one-year of terrestrial weathering was not severe yet. However, our reported values are higher than derived from polymict (brecciated) ureilites 4.38 ± 0.47 log 10-9 Am2/kg (Rochette et al. 2009) containing both falls and finds confirming that these are significantly weathered. Additionally other fresh-looking meteorites of non-ureilitic compositions were collected in the Almahata Sitta strewn field. Magnetic susceptibility measurements proved to be a convenient non-destructive method for identifying non-ureilitic meteorites among those collected in the Almahata Sitta strewn field, even among fully crusted. Three such meteorites, no. 16, 25, and 41, were analyzed and their composition determined as EH6, H5 and EL6 respectively (Zolensky et al., 2010). A high scatter of magnetic susceptibility values among small (< 5 g) samples revealed high inhomogeneity within the 2008 TC3 material at scales below 1-2 cm.

Kolmas tehtävä ja neljäs valtiomahti. Uusi yliopistolaki ja yliopiston rooli yhteiskunnassa julkisen keskustelun kohteena 2008-2009.

Tässä pro gradu -tutkielmassa tarkastellaan yliopiston yhteiskunnallista vuorovaikutusta koskevaa julkista keskustelua. Aineisto koostuu viiden levikiltään Suomen suurimpien joukkoon kuuluvan sanomalehden yliopiston yhteiskunnallista vuorovaikutusta käsittelevistä pääkirjoituksista ajalta 1.1.2008–31.12.2009. Pääkirjoituksia on aineistossa yhteensä 110. Tutkielman tarkoituksena on täydentää politiikan tutkimuksen alalla laiminlyötyä koulutuspolitiikan tutkimusta paneutuen yliopiston yhteiskunnallista roolia koskeviin merkityksiin, jotka nousivat aktiiviseen julkiseen keskusteluun yliopistolain uudistuksen myötä. Tutkimuskysymyksenä on, minkälaisia representaatioita yliopiston roolista yhteiskunnassa suomalaiset sanomalehdet välittivät pääkirjoituksissaan uuden yliopistolain säätämistä edeltäneessä uutisoinnissaan? Tutkielmassa eritellään pääkirjoituksista löytyviä yliopiston yhteiskunnallista roolia koskevia merkitysjärjestelmiä eli diskursseja käyttäen menetelmänä Teun van Dijkin diskurssianalyysia. Yliopiston roolia koskevia representaatioita tarkastellaan Jürgen Habermasin tiedon intressien teoriaan peilaten. Muita keskeisiä teoreetikkoja ovat Gerard Delanty, Henry Etzkowitz, Helga Nowotny, Jean-Francois Lyotard, Andy Green ja Marek Kwiek. Yliopiston kolmannen tehtävän korostumista pohjustetaan historiallisella kuvauksella modernin yliopiston synnystä ja yliopistoinstituution kehityksestä Euroopassa ja tarkemmin Suomessa. Työssä käydään myös läpi tutkimusta, joka pureutuu kansallisvaltion ja yliopistoinstituution historiallisen siteen purkautumiseen ja yliopiston toiminnan legitimiteetin uudelleenmäärittelyyn. Lisäksi nostetaan esiin näkemyksiä tiedon tuotannon monopolin irtautumisesta yliopistolta yhä suuremmalle joukolle toimijoita. Analyysia taustoitetaan myös uuden yliopistolain ja sen taustalla olleen ylikansallisen koulutuspolitiikan konsensuksen kautta. Pääkirjoituksissa esiintyneitä yliopiston yhteiskunnallisen roolin saamia merkityksiä tarkastellaan ensin lehtikohtaisesti, minkä jälkeen pääkirjoitusten sisältämistä representaatioista muodostetaan diskursseja. Aineistosta muodostui viisi diskurssia: globaalin selviämistaistelun diskurssi, lokaalin identiteetin diskurssi, maineenrakennuksen diskurssi, panos-tuotos-diskurssi ja myyttisen humboldtilaisuuden diskurssi. Yliopisto representoitiin alueellisen identiteetinrakennuksen ja integraation välineenä ja sellaiseksi alueen integraation välineeksi, jolle valtio on prosessin laidalla oleva tukiverkko. Alueen integraation välineeksi representoitu yliopisto esitettiin samalla globaalille huipulle tähtäämisen myötä legitimoituvaksi instituutioksi. Yliopisto representoitiin siis glokaalin huipulle nousun välineenä. Pääkirjoituksissa epäpolitisoitiin yliopiston ja alueen välinen yhteys sekä yliopiston ja elinkeinoelämän välinen yhteys. Globaalin selviämistaistelun ja myyttisen humboldtilaisuuden välinen merkityskamppailu kulki läpi aineiston. Yliopisto representoitiin teknisen tiedon intressin mukaisesti välineeksi globaalin kilpailukyvyn nostamiseksi. Toisaalta yliopisto esitettiin myös myyttisen humboldtilaiseksi puhdasta tutkimusta tekeväksi ympäröivästä yhteiskunnasta eristäytyneeksi instituutioksi. Aineistossa ei representoitu yliopistoa emansipatorista tiedon intressiä toteuttavana instituutiona vaihtoehtona teknisen tiedon intressin mukaisille representaatioille. Myöskään kommunikatiivisen tiedon intressin mukainen yliopisto ei tullut aineistossa esiin. Aineistossa annettiin vastoin tutkimuskirjallisuuden näkemyksiä yliopistolle legitiimin tiedon monopolin haltijan rooli. Pääkirjoituksissa representoitiin valtiovallan, yksityisen sektorin ja tiedeyhteisön yliopistoa koskevia intressejä. Kansalaisyhteiskunnan ja yliopiston välistä vuorovaikutusta aineisto ei nostanut esiin. Keskeisimmäksi jatkotutkimuksen aiheeksi identifioitiin tämän myötä yliopiston ja kansalaisyhteiskunnan toimijoiden välisen vuorovaikutuksen tarkastelu.

Taloustilanteen heikkenemisestä johtuvat muutokset asuntosijoittamiseen pääkaupunkiseudulla 2008

Tutkielman tavoitteena on selvittää miten taloustaantuma vaikutti asuntosijoittamisen kiinnostavuuteen ja asuntomarkkinoilla käytävään keskusteluun vuonna 2008. Tuolloin Suomen talous taantui voimakkaasti ja nopeasti yllättäen myös ennusteita laativat asiantuntijat. Ekonomistien lausunnoista puuttui yhdenmukaisuus ja tarkkuus. Ne myös saattoivat muuttua merkittävästi lyhyellä aikavälillä. Taantumassa sijoitusviestintä on varovaista ja tarkasti muotoiltua. Sijoittajat uskovat mielellään muiden sijoittajien mielipiteitä ja käsityksiä vaikkei niiden taustalla olisikaan aina todennettua faktatietoa. Asiantuntijoiden tilastoihin halutaan uskoa vaikka niitä kohtaan koetaan epäilyksiä. Toisaalta asuntosijoittamisen kannattavuuteen ja taloudelliseen tuottoon halutaan uskoa vaikka asiantuntijat voisivat todistaa toisin. Tutkimus toteutettiin kvalitatiivisena tapaustutkimuksena jota analysoitiin Greimasin aktanttimallia mukaillen. Tutkimusaineisto koostui 14 Helsingin Sanomissa julkaistuista asuntosijoittamiseen liittyvistä artikkelista sekä 13 Taloussanomien keskustelupalstalla julkaistusta mielipidekirjoituksesta. Viestien merkityksiä käytiin läpi semioottisesti määrittelemällä eri aktanteille rooleja. Tarinassa sijoittajasubjektin objektina on asunto, jonka avulla pyritään saavuttamaan mahdollisimman suuri rahallinen tuotto. Lähettäjiä ovat muun muassa tilastojen laatijat ja sijoitusneuvojat. Kaikki optimaalisen sijoituspäätöksen tekemiseen vaikuttavat aktantit käydään tarkemmin läpi tutkimuksen loppupuolella.
