Cortical processing of musical pitch as reflected by behavioural and electrophysiological evidence

In a musical context, the pitch of sounds is encoded according to domain-general principles not confined to music or even to audition overall but common to other perceptual and cognitive processes (such as multiple pattern encoding and feature integration), and to domain-specific and culture-specific properties related to a particular musical system only (such as the pitch steps of the Western tonal system). The studies included in this thesis shed light on the processing stages during which pitch encoding occurs on the basis of both domain-general and music-specific properties, and elucidate the putative brain mechanisms underlying pitch-related music perception. Study I showed, in subjects without formal musical education, that the pitch and timbre of multiple sounds are integrated as unified object representations in sensory memory before attentional intervention. Similarly, multiple pattern pitches are simultaneously maintained in non-musicians' sensory memory (Study II). These findings demonstrate the degree of sophistication of pitch processing at the sensory memory stage, requiring neither attention nor any special expertise of the subjects. Furthermore, music- and culture-specific properties, such as the pitch steps of the equal-tempered musical scale, are automatically discriminated in sensory memory even by subjects without formal musical education (Studies III and IV). The cognitive processing of pitch according to culture-specific musical-scale schemata hence occurs as early as at the sensory-memory stage of pitch analysis. Exposure and cortical plasticity seem to be involved in musical pitch encoding. For instance, after only one hour of laboratory training, the neural representations of pitch in the auditory cortex are altered (Study V). However, faulty brain mechanisms for attentive processing of fine-grained pitch steps lead to inborn deficits in music perception and recognition such as those encountered in congenital amusia (Study VI). These findings suggest that predispositions for exact pitch-step discrimination together with long-term exposure to music govern the acquisition of the automatized schematic knowledge of the music of a particular culture that even non-musicians possess.

Muslimioppilas suomalaisessa peruskoulussa : Tapaustutkimus kahden muslimitytön sopeutumisesta suomalaiseen peruskouluun

Tutkielma on etnografisella tutkimusotteella toteutettu tapaustutkimus, jossa oli tutkimuskohteena yksi pääkaupunkiseudun peruskoulun neljäs luokka. Tutkimus suoritettiin kevätlukukaudella 1998. Luokalla oli 24 oppilasta, joista kaksi oli somalialaisia muslimityttöjä. Aineistonkeruumenetelmiä olivat osallistuva havainnointi, teemahaastattelut, keskustelut ja luokan oppilaiden kirjoittamat kirjoitelmat. Tutkimustehtävänä oli kuvata ja ymmärtää muslimityttöjen olemassaolon vaikutusta luokan arkipäivään luokan eri osapuolien kannalta. Kiinnostuksen kohteena oli, miten opettaja ja luokan muut oppilaat suhtautuivat muslimityttöihin ja millaisia olivat muslimityttöjen omat kokemukset luokan elämästä ja miten heidän uskontonsa, islam, näkyi koulupäivän aikana. Tutkimustuloksista: Islam näkyi koulupäivän aikana konkreettisimmin muslimityttöjen pukeutumisessa ja ruokailussa. He saivat myös islaminuskon opetusta, harjoittelivat paastoamista paastokuukauden aikana ja heillä oli lupa olla pois koulusta muslimien juhlapyhinä. Luokan muut oppilaat tiesivät, että muslimitytöillä oli eri uskonto kuin heillä, mutta he eivät uskoneet sen vaikuttavan muslimityttöjen koulupäivään kovinkaan paljon. Muslimitytöt olivat solmineet ystävyyssuhteita luokan suomalaisiin tyttöihin ja he viihtyivät hyvin heidän kanssaan. Muslimityttöjä oli kuitenkin kiusattu enemmän kuin luokan muita oppilaita, mutta kiusaaminen oli vähentynyt ajan kuluessa. Muutamilla luokan pojilla oli halveksiva tai vihamielinen suhtautuminen muslimityttöihin. Muslimityttöjen koulunkäyntiin liittyi joitakin vaikeuksia, kuten oppimisvaikeudet muutamissa aineissa ja vaikeudet sopeutua tiettyihin koulun sääntöihin. Luokanopettaja koki yhteistyön muslimityttöjen vanhempien kanssa vaikeaksi. Näistä ongelmista huolimatta muslimitytöillä oli myönteinen suhtautuminen koulunkäyntiin. Tässä tapauksessa muslimitytöt olivat saavuttaneet integraatio-vaiheen Berryn akkulturaatio teorian mukaan. Sopeutuminen peruskoululuokkaan oli onnistunut heiltä hyvin lähinnä luokanopettajan toiminnan johdosta. He puhuivat hyvin suomen kieltä ja olivat asuneet Suomessa jo usean vuoden ajan, mikä myös helpotti sopeutumista.

Widening Perspectives of Teacher Education : Studies on theory-practice relationship, reflection, research and professional development

This dissertation examined the research-based teacher education at the University of Helsinki from different theoretical and practical perspectives. Five studies focused on these perspectives separately as well as overlappingly. Study I focused on the reflection process of graduating teacher students. The data consisted of essays the students wrote as their last assignment before graduating, where their assignment was to examine their development as researchers during their MA thesis research process. The results indicated that the teacher students had analysed their own development thoroughly during the process and that they had reflected on theoretical as well as practical educational matters. The results also pointed out that, in the students’ opinion, personally conducted research is a significant learning process. -- Study II investigated teacher students’ workplace learning and the integration of theory and practice in teacher education. The students’ interviews focused on their learning of teacher’s work prior to education. The interviewees’ responses concerning their ‘surviving’ in teaching prior to teacher education were categorized into three categories: learning through experiences, school as a teacher learning environment, and case-specific learning. The survey part of the study focused on integration of theory and practice within the education process. The results showed that the students who worked while they studied took advantage of the studies and applied them to work. They set more demanding teaching goals and reflected on their work more theoretically. -- Study III examined practical aspects of the teacher students’ MA thesis research as well as the integration of theory and practice in teacher education. The participants were surveyed using a web-based survey which dealt with the participants’ teacher education experiences. According to the results, most of the students had chosen a practical topic for their MA thesis, one arising from their work environment, and most had chosen a research topic that would develop their own teaching. The results showed that the integration of theory and practice had taken place in much of the course work, but most obviously in the practicum periods, and also in the courses concerning the school subjects. The majority felt that the education had in some way been successful with regards to integration. -- Study IV explored the idea of considering teacher students’ MA thesis research as professional development. Twenty-three teachers were interviewed on the subject of their experiences of conducting research about their own work as teachers. The results of the interviews showed that the reasons for choosing the MA thesis research topic were multiple: practical, theoretical, personal, professional reasons, as well as outside effect. The objectives of the MA thesis research, besides graduating, were actual projects, developing the ability to work as teachers, conducting significant research, and sharing knowledge of the topic. The results indicated that an MA thesis can function as a tool for professional development, for example in finding ways for adjusting teaching, increasing interaction skills, gaining knowledge or improving reflection on theory and/or practice, strengthening self-confidence as a teacher, increasing researching skills or academic writing skills, as well as becoming critical and being able to read scientific and academic literature. -- Study V analysed teachers’ views of the impact of practitioner research. According to the results, the interviewees considered the benefits of practitioner research to be many, affecting teachers, pupils, parents, the working community, and the wider society. Most of the teachers indicated that they intended to continue to conduct research in the future. The results also showed that teachers often reflected personally and collectively, and viewed this as important. -- These five studies point out that MA thesis research is and can be a useful tool for increasing reflection doing with personal and professional development, as well as integrating theory and practice. The studies suggest that more advantage could be taken of the MA thesis research project. More integration of working and studying could and should be made possible for teacher students. This could be done in various ways within teacher education, but the MA thesis should be seen as a pedagogical possibility.

Matka koulun kestävän kehittämisen maisemassa

A Journey in the Landscape of Sustainable School Development “A Journey in the Landscape of Sustainable School Development” is a story of the Sorrila School development process. This research deals with a school development project as a process, and as a part of international projects on Education for Sustainable Development, with ENSI (Environment and School Initiatives) being the most important. The main purpose of the study was to analyze the change process as a general phenomenon as well as the learning connected to it. The research describes the development period 2001–2008 at the Sorrila Primary school. The research questions are as follows: 1. What did pupils learn during the research and development period? 2. How did the coordinating teacher develop personally? 3. How were the ENSI targets and other closely linked projects reached? 4. What was the feedback from the pupils, their parents and other teachers at the school? 5. How did the developing process proceed in 2001–2008? The method used was integrating action research, which also had ethnographical elements. Narrative was the form of the data as well as the manner of reporting. The method as a whole was integrating, ethnographical action research as a story. The research data consisted mostly of Knowledge Forum notes written by the teacher-researcher. Knowledge Forum is an Internetbased collaborative knowledge-building programme. Pupils’, parents’ and other teachers’ feedback, newspaper articles and students’ writings complied the data, which consists of material from seven years. Sustainable development was the basis of the school improvement. The targets of the United Nations Decade of Education for Sustainable Development (2005–2014) were part of the development projects. According to the research results the school was seen as part of complex systems where manifold and interactive learning took place. The learning of pupils, teachers and the school as a community can be characterised socioculturally. The school was able to reach a level of collaborative transformative learning. As well as several concrete projects, such as Comenius school project, school development consisted of networking at many levels. Along with the projects and networking, the school was able to apply the pedagogy of connection, by carrying out integrative and cross-disciplinary themes and using various learning and teaching methods. International cooperation was a natural part of the work. A figure of Aunt Green, the role model of the teacher researcher, was an innovation which resembled a change agent. The other role of the teacherresearcher as a coordinator, was important for her own professional development. According to the results the change process, which relied on sustainable school development, led the school along a road of positive renewals. It was not a series of projects but an ongoing process. The objectives of the international projects were accomplished to a great extent during the research period. According to the principles of action research, the main results were put forward in order to help others to develop their schools. Frictions and problems as well as positive experiences and rejecting dualities were seen as change forces. Keywords: education for sustainable development (ESD), sustainable school development, teacher professional development, integrating, pedagogy of connection, transformative learning

Foreign Capital and Finland : Central government's first period of reliance on international financial markets, 1862-1938

The main objective of the study is to evaluate the Finnish central government s foreign borrowing between the years 1862 and 1938. Most of this period was characterised by deep capital market integration that bears resemblance to the liberal world financial order at the turn of the millennium. The main aim is to analyse the credit risk associated with the state and its determination by evaluating the world financial market centres perception of Finland. By doing this, the study is also expected to provide an additional dimension to Finland s political and economic history by incorporating into the research the assessments of international capital markets regarding Finland during a period that witnessed profound political and economic changes in Finnish society. The evaluation of the credit risk mainly relies on exchange-rate risk free time series of the state s foreign bonds. They have been collected from quotations in the stock exchanges in Helsinki, Hamburg, Paris and London. In addition, it investigates Finland s exposure to short-term debt and Moody s credit ratings assigned to Finland. The study emphasises the importance of the political risk. It suggests that the hey-day of the state s reliance on foreign capital markets took place during last few decades of the 19th century when Finland enjoyed a wide autonomy in the Russian Empire and prudently managed its economy, highlighted in Finland s adherence to the international gold standard. Political confrontations in Finland and, in particular, in Russia and the turbulence of the world financial system prevented the return of this beneficial position again. Through its issuance of foreign bonds the state was able to import substantial amounts of foreign capital, which was sorely needed to foster economic development in Finland. Moreover, the study argues that the state s presence in the western capital markets not only had economic benefits, but it also increased the international awareness of Finland s distinct and separate status in the Russian Empire and later underlined its position as an independent republic.

Small State Cultures of Consensus : State Traditions and Consensus-Seeking in the Neo-Corporatist and Neutrality Policies in Post-1945 Austria and Finland

Austria and Finland are persistently referred to as the “success stories” of post-1945 European history. Notwithstanding their different points of departure, in the course of the Cold War both countries portrayed themselves as small and neutral border-states in the world dictated by superpower politics. By the 1970s, both countries frequently ranked at the top end in various international classifications regarding economic development and well-being in society. This trend continues today. The study takes under scrutiny the concept of consensus which figures centrally in the two national narratives of post-1945 success. Given that the two domestic contexts as such only share few direct links with one another and are more obviously different than similar in terms of their geographical location, historical experiences and politico-cultural traditions, the analogies and variations in the anatomies of the post-1945 “cultures of consensus” provide an interesting topic for a historical comparative and cross-national examination. The main research question concerns the identification and analysis of the conceptual and procedural convergence points of the concepts of the state and consensus. The thesis is divided into six main chapters. After the introduction, the second chapter presents the theoretical framework in more detail by focusing on the key concepts of the study – the state and consensus. Chapter two also introduces the comparative historical and cross-national research angles. Chapter three grounds the key concepts of the state and consensus in the historical contexts of Austria and Finland by discussing the state, the nation and democracy in a longer term comparative perspective. The fourth and fifth chapter present case studies on the two policy fields, the “pillars”, upon which the post-1945 Austrian and Finnish cultures of consensus are argued to have rested. Chapter four deals with neo-corporatist features in the economic policy making and chapter five discusses the building up of domestic consensus regarding the key concepts of neutrality policies in the 1950s and 1960s. The study concludes that it was not consensus as such but the strikingly intense preoccupation with the theme of domestic consensus that cross-cut, in a curiously analogous manner, the policy-making processes studied. The main challenge for the post-1945 architects of Austrian and Finnish cultures of consensus was to find strategies and concepts for consensus-building which would be compatible with the principles of democracy. Discussed at the level of procedures, the most important finding of the study concerns the triangular mechanism of coordination, consultation and cooperation that set into motion and facilitated a new type of search for consensus in both post-war societies. In this triangle, the agency of the state was central, though in varying ways. The new conceptions concerning a small state’s position in the Cold War world also prompted cross-nationally perceivable willingness to reconsider inherited concepts and procedures of the state and the nation. At the same time, the ways of understanding the role of the state and its relation to society remained profoundly different in Austria and Finland and this basic difference was in many ways reflected in the concepts and procedures deployed in the search for consensus and management of domestic conflicts.

EU Multi-level Governance in the Making - The Community Initiative LEADER+ in Finland and Germany

In order to fully understand the process of European integration it is of paramount importance to consider developments at the sub-national and local level. EU integration scholars shifted their attention to the local level only at the beginning of the 1990s with the concept of multi-level governance (MLG). While MLG is the first concept to scrutinise the position of local levels of public administration and other actors within the EU polity, I perceive it as too optimistic in the degree of influence it ascribes to local levels. Thus, learning from and combining MLG with other concepts, such as structural constructivism, helps to reveal some of the hidden aspects of EU integration and paint a more realistic picture of multi-level interaction. This thesis also answers the call for more case studies in order to conceptualise MLG further. After a critical study of theories and concepts of European integration, above all, MLG, I will analyse sub-national and local government in Finland and Germany. I show how the sub-national level and local governments are embedded in the EU s multi-level structure of governance and how, through EU integration, those levels have been empowered but also how their scope of action has partially decreased. After theoretical and institutional contextualisation, I present the results of my empirical study of the EU s Community Initiative LEADER+. LEADER stands for Liaison Entre Actions de Développement de l'Économie Rurale , and aims at improving the economic conditions in Europe s rural areas. I was interested in how different actors construct and shape EU financed rural development, especially in how local actors organised in so-called local action groups (LAGs) cooperate with other administrative units within the LEADER+ administrative chain. I also examined intra-institutional relations within those groups, in order to find out who are the most influential and powerful actors within them. Empirical data on the Finnish and German LAGs was first gathered through a survey, which was then supplemented and completed by interviewing LAG members, LAG-managers, several civil servants from Finnish and German decision-making and managing authorities and a civil servant from the EU Commission. My main argument is that in both Germany and Finland, the Community Initiative LEADER+ offered a space for multi-level interaction and local-level involvement, a space that on the one hand consists of highly motivated people actively contributing to the improvement of the quality of life and economy in Europe s countryside but which is dependent and also restricted by national administrative practices, implementation approaches and cultures on the other. In Finland, the principle of tri-partition (kolmikantaperiaatte) in organising the executive committees of LAGs is very noticeable. In comparison to Germany, for instance, the representation of public administration in those committees is much more limited due to this principle. Furthermore, the mobilisation of local residents and the bringing together of actors from the local area with different social and institutional backgrounds to become an active part of LEADER+ was more successful in Finland than in Germany. Tri-partition as applied in Finland should serve as a model for similar policies in other EU member states. EU integration changed the formal and informal inter-institutional relations linking the different levels of government. The third sector including non-governmental institutions and interest groups gained access to policy-making processes and increasingly interact with government institutions at all levels of public administration. These developments do not necessarily result in the empowering of the local level.

Essays on Economic Integration and Labour Demand

This dissertation consists of an introductory section and three essays investigating the effects of economic integration on labour demand by using theoretical models and by empirical analysis. The essays adopt an intra-industry trade approach to specify a theoretical framework of estimation for determining the effects of economic integration on employment. In all the essays the empirical aim is to explore the labour demand consequences of European integration. The first essay analyzes how labour-demand elasticities with own price have changed during the process of economic integration. As a theoretical result, intensified trade competition increases labour-demand elasticity, whereas better advantage of economies of scale decreases labour-demand elasticity by decreasing the elasticity of substitution between differentiated products. Furthermore, if integration gives rise to an increase in input-substitutability and/or outsourcing activities, labour demand will become more elastic. Using data from the manufacturing sector from 1975 to 2002, the empirical results provide support for the hypothesis that European integration has contributed to increased elasticities of total labour demand in Finland. The second essay analyzes how economic integration affects the impact of welfare poli-cies on employment. The essay considers the viability of financing the public sector, i.e. public consumption and social security expenses, by general labour taxation in an economy which has become more integrated into international product markets. The theoretical results of the second essay indicate that, as increased trade competition crowds out better economies of scale, it becomes more costly to maintain welfare systems financed by labour taxation. Using data from European countries for the years 1975 to 2004, the empirical results provide inconsistent evidence for the hypothesis that economic integration has contributed to the distortion effects of welfare policies on employment. The third essay analyzes the impact of profit sharing on employment as a way to introduce wage flexibility into the process of economic integration. The results of the essay suggest that, in theory, the effects of economic integration on the impact of profit sharing on employment clearly depend on a trade-off between intensified competition and better advantage of economies of scale. If product market competition increases, the ability of profit sharing to improve employment through economic integration increases with moderated wages. While, the economic integration associating with market power in turn decrease the possibilities of profit sharing with higher wages to improve employment. Using data from the manufacturing sector for the years 1996 to 2004, the empirical results show that profit-sharing has a positive impact on employment during the process of European integration, but can have ambiguous effects on the stability of employment in Finland.

Towards a United States of Africa? Combining Zambian and AU level debate.

Globalisaatio on luonut uuden maailmanjärjestelmän jonka myötä yksittäisten valtioiden vaikutusvalta on vähentynyt entisestään. Tämä pitää paikkansa erityisesti kehittyvien maiden kohdalla, esimerkiksi Afrikassa. Afrikka on pyrkinyt taistelemaan globalisaation tuomia negatiivisia vaikutuksia vastaan alueellistumisen ja maanosan yhtenäisyyttä ajavien hankkeiden kautta jo vuosikymmenien ajan, mutta toistaiseksi tulokset eivät ole olleet vakuttavia. Tällä hetkellä Afrikan Unionissa keskustellaan hankkeesta muodostaa Afrikan Yhdysvallat. Aiemmista hankkeista poiketen tämän uuden aloitteen ajatus perustuu ylikansallisuudelle, jossa yksittäiset valtiot luovuttavat valtaansa ylikansallisille elimille, kuten Afrikan Unionin hallitukselle. Näin ollen on tärkeää tarkastella aloitetta Afrikan Yhdysvaltojen perustamiseksi ja arvioida, voisiko tällainen ylikansallinen organisaatio auttaa Afrikkaa kääntämään globalisaation haittavaikutukset myönteisiksi. Tämä Pro Gradu-tutkielma väittää sen olevan mahdollista, mutta vain siinä tapauksessa että Afrikka on valmis hyväksymään yhtenäisyyden rajoitukset. Aiemman tutkimuksen vähyyden vuoksi on myös tarpeen tutkia Afrikan Yhdysvalloista kansallisilla tasoilla käytävää keskustelua. Tämän vuoksi tässä tutkielmassa painotetaan esimerkkimaa Sambian kautta yhden Afrikan Unionin jäsenmaan keskinäistä keskustelua aiheesta ja verrataan sitä Afrikan Unionin tason keskusteluun. Tutkielma sisältää kirjallisuuskatsauksen sekä tapaustutkimuksen. Tutkimusaineisto koostuu sambialaisista sanomalehtiotteista sekä Sambian valtion ja Afrikan Unionin virallisista asiakirjoista. Pääasiallisena tutkimusmenetelmänä on laadullinen sisällönanalyysi. Teoreettinen viitekehys perustuu afrikkalaisen valtion ja kansalaisyhteiskunnan, alueellistumisen, globalisaation hallinnan, pan-afrikkalaisuuden ja poliittisen integraation teorioihin sekä historialliseen katsaukseen Afrikan yhtenäisyydestä. Perimmäisenä tarkoituksena on lisätä ymmärrystä afrikkalaisesta valtiosta ja politiikasta. Tutkimuksen tulosten mukaan on havaittavissa aukko valtioiden virallisten toimijoiden näkemysten ja kansalaisyhteiskunnan huolenaiheiden välillä. Viralliset toimijat näyttävät olevan kansalaisyhteiskuntaa vahvemmin Afrikan Yhdysvaltojen kannalla. Virallisten toimijoiden korostaessa Afrikan aatteellista yhtenäisyyttä kansalaisyhteiskunta on huolissaan sen toteutumisesta käytännössä. Esiin nousee myös kysymys 'afrikkalaisesta' identiteetistä ja kansalaisuudesta sekä kommunikaatiosta valtion ja kansalaisten välillä.

Nile Basin Initiative diskursiivisena areenana

Pro gradu -tutkielma käsittelee Niilin alueen poliittista kehitystä käyttäen viitekehyksenä Barry Buzanin, Ole Wæverin sekä Jaap de Wilden muodostaman Kööpenhaminan koulukunnan teoriaa turvallistamisesta sekä turvallisuuskomplekseista. Niilin kymmenen valtiota kattavan jokialueen poliittista historiaa on vuosikymmenet hallinnut valtioiden välinen epäluottamus, ja erityisesti Egypti, joka on täysin riippuvainen Niilin vesivaroista, on julistanut Niilin vesivarojen olevan sille kansallinen turvallisuuskysymys, ja se on uhannut käyttää myös voimakeinoja puolustaakseen vedenkäyttöoikeuksiaan. Egyptiä on myös voitu Niilin alueen hegemonina, sillä vanhat, alun perin siirtomaa-ajalta peräisin olevat sopimukset ovat antaneet sille lähes yksinoikeuden Niilin vesivarojen käyttöön. Samanaikaisesti erityisesti Etiopia, jonka alueelta suurin osa joen vesivaroista on peräisin, on pitänyt vanhoja sopimuksia epäreiluina, ja vedonnut maassa kasvavaan nälänhätään ja ruokapulaan, mutta myös useat muut alueen valtiot ovat esittäneet tyytymättömyytensä vanhoihin sopimuksiin. Vuonna 1999 kehityksessä tapahtui kuitenkin käänne, sillä jokilaakson valtiot perustivat tuolloin Niilin jokialueen yhteistyöjärjestön Nile Basin Initiativen (NBI). Tutkielma keskittyy NBI:n perustamisen jälkeiseen ajanjaksoon. Keskeinen tutkimuskysymys on, millä tavalla Niilin alueen jäsenvaltiot pyrkivät 2000-luvun alkupuolella keskinäisellä toiminnallaan muuttamaan alueella vallitsevaa kilpailu- ja konfliktiasetelmaa rauhanomaiseen suuntaan. Aineistona käytetään NBI:n omia kausijulkaisuja vuosilta 2006–2010, ja tutkimuksen menetelmänä käytetään diskurssianalyysia. Tutkitun aineiston perusteella on esitettävissä, että Niilin alueen poliittisesta kehityksestä on selvästi erotettavissa diskursseja, jotka ovat NBI:n toiminnan taustalla. Nämä ovat luottamuksen rakentamisen, yhteisten haasteiden voittamisen, yhteistyön tärkeyden sekä saavutusten diskurssit. Aineiston perusteella on nähtävissä, että valtioiden välisen luottamuksen vähitellen lisääntyessä yhteistyötä aletaan yhä enemmän legitimoida aikaisemmin yhteistyöstä saavutetuilla hyödyillä. Toisaalta diskurssianalyysin perusteella on myös nähtävissä, että alueella on ratkaisematta yhä fundamentaalisia ongelmia; uutta vesisopimusta ei ole vielä vuoteen 2010 mennessä aikaansaatu ja NBI:n jäsenvaltioiden suhteissa on myös nähtävissä kiistaa periaatteista, joihin yhteistyön olisi pohjauduttava. Tutkielma pyrkii analyysin avulla kehittämään myös Kööpenhaminan koulukunnan teoriaa turvallistamisesta. Kööpenhaminan koulukunta jättää turvallistamisen purkamiskehityksen kirjoituksissaan taka-alalle keskustelun painottuessa siihen, kuinka jokin asia tuodaan esille julkiseen turvallisuuskeskusteluun. Tältä osin tutkimuksen tavoitteena on esittää mahdollinen kehityskulku turvallistamisen purkamisdiskurssista.

EU-aikakauden ympäristötaisto. Ympäristöjärjestöjen toiminnan eurooppalainen ulottuvuus kiistassa Vuosaaren sataman rakentamisesta

Tutkimuksen tavoitteena on selvittää mitä kiista Vuosaaren sataman rakentamisesta 1990- ja 2000-luvuilla kertoo eurooppalaisesta kollektiivisesta toiminnasta. Mikä on EU:n suhde ylirajaiseen kollektiiviseen toimintaan, joka syntyy unionin vaikutuksesta? Ympäristöjärjestöt Suomen Luonnonsuojeluliiton johdolla kantelivat satamahankkeesta Euroopan komissiolle ja tekivät vetoomuksen Euroopan parlamentille, koska suunnitellun sataman vieressä sijaitsi alue, joka kuului Natura 2000 –luonnonsuojeluverkostoon. Myös eurooppalaiset kattojärjestöt osallistuivat toimintaan. Aineistona on ympäristöjärjestötoimijoiden ja heidän kanssaan tekemisissä olleiden tahojen haastatteluja, asiakirjoja, sähköpostiviestejä sekä tiedotus- ja lehtimateriaalia. Satamakiistaa tutkitaan yhteiskunnallisten liikkeiden tutkimuksen perinteestä käsin. Kirjallisuudesta keskitytään erityisesti koalitionmuodostukseen, johon osallistuivat ympäristöjärjestöjen lisäksi myös Euroopan parlamentin vihreät, sekä ylirajaisen kollektiivisen toiminnan luonteen käsitteellisempään hahmottamiseen. Tapauksessa sinällään kotimainen konflikti ulkoistettiin viemällä se EU-tasolle. Bumerangi-ilmiössä valtioon yritettiin vaikuttaa EU-instituutioiden kautta. Tämän ulkoistamisen myötä syntyi ylirajainen kampanjakoalitio, joka perustui osin jäsenjärjestö-kattojärjestö-suhteeseen. Koalitiota voidaan vetoomusvaiheessa kuvailla parlamentin vihreiden mukanaolon myötä sisä- ja ulkopiiriläisten koalitioksi (insider-outsider coalition). Toiminnalla oli joitain samoja piirteitä edistämisverkostojen (transnational advocacy networks) kanssa. Syy sekä kansallisten ympäristöjärjestöjen että kattojärjestöjen aktiivisuudelle oli tapauksen oikeudellinen ennakkotapausmerkitys, joten protestikeinojen hyöty olisi ollut vähäinen. Natura pitkälti loi ympäristöjärjestöille merkityksellisen kiistan. Koska haluttiin vaikuttaa lainkäyttöön, itse tapaus oli keino, ja kantelut olivat keinon ominaisuus. Ylipäätään valittamisen mahdollistavan EU-mahdollisuusrakenteen vuoksi järjestöt pystyivät tietyllä tapaa uudelleenpolitisoimaan kansallisesti jo oikeusistuinvaiheeseen siirtyneen kiistan viemällä asian vähemmän oikeudellisille areenoille. Tapauksessa politiikka juridisoitui ja juridiikka myös politisoitui. Kantelujen voidaan kuvata olevan osa eurooppalaista yhteiskuntaa, mutta prosessin edetessä ja vetoomuksen myötä ylirajainen kollektiivinen toiminta vähitellen monipuolistui ja syveni siten, että tapauksesta voidaan hahmottaa myös eurooppalainen kansalaisyhteiskunta.

Kädestä suuhun : Makro- ja mikrotaloudellinen tarkastelu suomalaisten kotitalouksien säästämisestä ja sen mittaamisesta 1950-luvulla

This study is divided into two parts: a methodological part and a part which focuses on the saving of households. In the 1950 s both the concepts as well as the household surveys themselves went through a rapid change. The development of national accounts was motivated by the Keynesian theory and the 1940 s and 1950 s were an important time for the development of the national accounts. Before this, saving was understood as cash money or money deposited in bank accounts but the changes in this era led to the establishment of the modern saving concept. Separate from the development of national accounts, household surveys were established. Household surveys have been conducted in Finland from the beginning of the 20th century. At that time surveys were conducted in order to observe the working class living standard and as a result, these were based on the tradition of welfare studies. Also a motivation for undertaking the studies was to estimate weights for the consumer price index. A final reason underpinning the government s interest in observing this data regarded whether there were any reasons for the working class to become radicalised and therefore adopt revolutionary ideas. As the need for the economic analysis increased and the data requirements underlying the political decision making process also expanded, the two traditions and thus, the two data sources started to integrate. In the 1950s the household surveys were compiled distinctly from the national accounts and they were virtually unaffected by economic theory. The 1966 survey was the first study that was clearly motivated by national accounts and saving analysis. This study also covered the whole population rather than it being limited to just part of it. It is essential to note that the integration of these two traditions is still continuing. This recently took a big step forward as the Stiglitz, Sen and Fitoussi Committee Report was introduced and thus, the criticism of the current measure of welfare was taken seriously. The Stiglitz report emphasises that the focus in the measurement of welfare should be on the households and the macro as well as micro perspective should be included in the analysis. In this study the national accounts are applied to the household survey data from the years 1950-51, 1955-56 and 1959-60. The first two studies cover the working population of towns and market towns and the last survey covers the population of rural areas. The analysis is performed at three levels: macro economic level, meso level, i.e. at the level of different types of households, and micro level, i.e. at the level of individual households. As a result it analyses how the different households saved and consumed and how that changed during the 1950 s.

Viljakylvösiemensektorin toimintaedellytykset

Viljakylvösiemensektorin toimintaympäristön muutoksiin on hyvä valmistautua ennalta ja pohtia toimintatapoja, joiden turvin toimia muuttuvassa toimintaympäristössä. Suomen kylvösiemenmarkkinat ovat pienentyneet voimakkaasti 1980-luvun lopulta lähtien. 2000-luvulla sertifioidun siemenen käyttöaste on ollut keskimäärin vain 30 % ja viljojen kohdalla käyttöaste on ollut tätäkin alhaisempi. Tulevaisuudessa yhteisen maatalouspolitiikan uudistukset, kiristyvä kilpailu, ilmastonmuutos, teknologian kehitys, kulutustottumusten muutokset sekä lähivuosina uudistava EU:n siemenlainsäädäntö tulevat muokkaamaan alan toimintaympäristöä. Jotta tulevaisuuden haasteisiin voidaan vastata, kartoitettiin tutkimuksessa asiantuntijoiden näkemyksiä siitä, mitkä ovat tuotantoketjun ongelmakohdat sekä alan toiminnan edistämismahdollisuudet. Työn teoreettisena viitekehyksenä oli toimialan taloustiede. Teorian rakennetta käytettiin siemenalan ongelmakohtien jäsentämiseen ja toimenpide-ehdotusten kartoittamiseen. Asiantuntijat näkivät sertifioidun siemenen heikkoon kysyntään vaikuttavan korvaavien tuotteiden, eli tilan oman kylvösiemen ja sertifioimattomana markkinoidun kylvösiemenen ns. harmaan siemenen, yleisyys. Tilan oman siemenen kohdalla suurin epäkohta on sen arvottamisessa. Harmaan siemenen käytön suosioon vaikuttavat sen edullisuuden lisäksi myös kaupan asiakaslähtöisyys. Sertifioidun siemenen kysyntää heikentävät myös puutteelliset markkinointitavat, kausivaihtelu sekä siemenmyyjien tietämättömyys viljelijöiden ostokäyttäytymisestä. Tarjonnan epäkohdiksi nousivat siemenestä saatava hinta, tuotantotekijäsidonnaisuus sekä hukkakauran leviäminen. Siemenestä saatu hinta ei aina riitä kattamaan paljon tuotantotekijöitä vaativan siementuotannon kustannuksia. Myös hukkakauran leviäminen vaikeuttaa ja rajoittaa tuotannon lisäämistä. Lisäksi siemenketjun kannalta ongelmia aiheuttivat teknologian ja tuotantoprosessien myönteinen mutta hidas kehitys. Markkinan rakenteen ongelmakohtina olivat markkinoiden oligopolisuisuus sekä tuotteiden tehoton erilaistaminen asiakkaiden tarpeiden mukaisesti. Alan yritysrakenteen todettiin olevan pienyritysvaltainen ja osin tehoton, vaikka rakennekehitystä onkin viime vuosina tapahtunut. Alalle tulon esteet liittyvät siemenviljelijöiden ja -pakkaajien kohdalla läheisesti tuotantotekijäsidonnaisuuteen sekä hukkakauran leviämiseen ja hukkakauralainsäädäntöön. Vastaavasti Suomen syrjäinen sijainti ja ilmasto- olosuhteet ovat pitäneet ulkomaisen kilpailun vähäisenä. Toimialan kustannusten todettiin jakaantuneen epätasaisesti siemenketjun toimijoiden välillä. Kustannusrakenteen todettiin olevan nykyisellään kestämätön ja tilanteen todettiin korjaantuvan ainoastaan tuntuvalla volyymin kasvulla. Lisäksi toimijoiden välinen vertikaalinen integraatio nähtiin vähäiseksi, vaikka sillä olisi merkittävä vaikutus tuotannon kannattavuuteen. Asiantuntijat näkivät maatalouspolitiikan sekä markkinoiden ja talouden muutosten etenevän eri suuntiin. Suurimpina epäkohtina nousivat siementuotannon tuen loppuminen sekä lainsäädännön asettamat rajoitukset. Lisäksi isona ongelmana pidettiin ulkoisen tiedottamisen tehottomuutta. Tutkimuksen perusteella viljakylvösiemensektorin toimintaedellytykset liittyvät pääasiallisesti markkinointiosaamisen ja informoinnin kehittämiseen sekä verkostoitumisen lisäämiseen. Tärkeänä osana toimintaedellytysten turvaamisessa on myös vaikuttaminen tulevaan EU:n siemenlainsäädäntöön siten, että kansalliset poikkeukset olisivat mahdollisia myös tulevaisuudessa.

Genomic alterations in Myeloproliferative Neoplasms and Myelodysplastic Syndromes

Myeloproliferative neoplasms (MPN) and myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematopoietic disorders whose etiology and molecular pathogenesis are poorly understood. During the past decade, enormous developments in microarray technology and bioinformatics methods have made it possible to mine novel molecular alterations in a large number of malignancies, including MPN and MDS, which has facilitated the detection of new prognostic, predictive and therapeutic biomarkers for disease stratification. By applying novel microarray techniques, we profiled copy number alterations and microRNA (miRNA) expression changes in bone marrow aspirate and blood samples. In addition, we set up and validated an miRNA expression test for bone marrow core biopsies in order to utilize the large archive material available in many laboratories. We also tested JAK2 mutation status and compare it with the in vitro growth pattern of hematologic progenitors cells. In the study focusing on 100 MPN cases, we detected a Janus kinase 2 (JAK2) mutation in 71 cases. We observed spontaneous erythroid colony growth in all mutation-positive cases in addition to nine mutation negative cases. Interestingly, seven JAK2V167F negative ET cases showed spontaneous megakaryocyte colony formation, one case of which also harbored a myeloproliferative leukemia virus oncogene (MPL) mutation. We studied copy number alterations in 35 MPN and 37 MDS cases by using oligonucleotide-based array comparative hybridization (array CGH). Only one essential thrombocythemia (ET) case presented copy number alterations in chromosomes 1q and 13q. In contrast, MDS cases were characterized by numerous novel cryptic chromosomal aberrations with the most common copy number losses at 5q21.3q33.1 and 7q22.1q33, while the most common copy number gain was trisomy 8. As for the study of the bone marrow core biopsy samples, we showed that even though these samples were embedded in paraffin and underwent decalcification, they were reliable sources of miRNA and suitable for array expression analysis. Further, when studying the miRNA expression profiles of the 19 MDS cases, we found that, compared to controls, two miRNAs (one human Epstein-Barr virus (miR-BART13) miRNA and one human (has-miR-671-5p) miRNA) were downregulated, whereas two other miRNAs (hsa-miR-720 and hsa-miR-21) were upregulated. However, we could find no correlation between copy number alterations and microRNA expression when integrating these two data. This thesis brings to light new information about genomic changes implicated in the development of MPN and MDS, and also underlines the power of applying genome-wide array screening techniques in neoplasias. Rapid advances in molecular techniques and the integration of different genomic data will enable the discovery of the biological contexts of many complex disorders, including myeloid neoplasias.
