Oligarchs, political regime changes, and firm valuation

This paper examines the impact of a regime shift on the valuation of politically powerful oligarch firms. Focusing on the Yeltsin-Putin regime shift in Russia, we find that the valuations of outside shareholders claims are significantly higher under the Putin regime than under the Yeltsin regime after controlling for industry and time effects. The findings suggest that the increasing cost of extracting private benefits outweigh the reduction in the value of political connections following the political regime change. The results are also consistent with changes in the risk of state expropriation. Our results show that effects driven by the political regime change complement the traditional view stating that increased ownership concentration improved the performance of Russian oligarch firms.

Gender and female entrepreneurship in a pro-entrepreneurship magazine

In this working paper I discuss gendered entrepreneurship by exploring how the media writes about female entrepreneurship. The starting point is that the media when talking and writing about female entrepreneurs and female entrepreneurship, mould meanings of gender in entrepreneurship. I view entrepreneurship and gender as socially constructed, discursive phenomena. To uncover the processes of constructing gender in female entrepreneurship this paper applies a discursive framework, which treats language as a representational system producing and circulating meaning. The focus on language use as action implies that practises of writing and talking about female entrepreneurship ‘make’ gender as much as the women entrepreneurs) themselves: both involve working on culturally shared meanings to make reality intelligible. The data consists of articles published in Yrittäjä, a pro-SME magazine, in 1990-1997. In the analysis I show how gender is constructed in media talk. as a women’s issue Women entrepreneurs are constantly compared with men and with an implicitly masculine ideal of entrepreneurship and with strengths and weaknesses of women are displayed pointing out that the meaning making of gender taking place in the data refers to equality discourse. Finally I discuss possible consequences of the hegemonic equality discourse and suggest lines of further research.

Kesämökkikäynnin virkistysarvon määrittäminen matkakustannusmenetelmällä

Tämän tutkielman tarkoituksena on määrittää kesämökkikäynnin virkistysarvo. Aihetta ei ole aikaisemmin tutkittu, vaikka kesämökkeily on merkittävä osa suomalaista elämää. Kesämökkikäynnin virkistysarvo tarkoittaa hyötyä, jonka yksilö saa kesämökillä virkistäytymisestä. Virkistäytyminen kesämökillä pitää sisällään kaiken kesämökillä ja sen ympäristössä tapahtuvan harrastamisen ja rentoutumisen. Koska ympäristö on tärkeässä osassa mökillä virkistäytymisessä, tässä tutkielmassa on lisäksi tarkoitus tutkia, kuinka mökkiympäristön ominaisuudet vaikuttavat virkistysarvoon. Tarkasteltavina ympäristön ominaisuuksina ovat virkistäytymisen estävät leväkukinnot ja mökin rannattomuus. Koska mökkeily toisaalta myös kuormittaa ympäristöä, tutkielmassa tutkitaan myös, kuinka sähköistys, ympäristöä kuormittava kesämökin ominaisuus, vaikuttaa virkistysarvoon. Virkistysarvo on markkinaton hyöty, joten sen määrittämiseen on käytettävä jotain markkinattomien hyödykkeiden arvottamismenetelmää. Tässä työssä arvottaminen tapahtuu matkakustannusmenetelmällä, jota käytetään yleisesti ympäristön tarjoamien virkistyspalveluiden taloudelliseen arvottamiseen. Kesämökkikäyntien kysyntää kuvaava matkakustannusmallin ekonometrinen mallintaminen suoritetaan negatiivisella binomimallilla. Tutkielman tulosten mukaan noin neljän päivän pituinen käynti sähköistetyllä kesämökillä, jossa on ranta eivätkä levät häiritse virkistäytymistä, tuottaa 167-205 euron suuruisen virkistyshyödyn. Virkistäytymisen estävät leväkukinnot laskevat arvoa 40 prosentilla ja mökin rannattomuus 45 prosentilla. Käynti sähköistetyllä mökillä tuottaa 3-5 prosenttia korkeamman virkistyshyödyn kuin käynti sähköistämättömällä mökillä. Suomessa kesän aikana tehtävien mökkikäyntien yhteenlaskettu virkistyshyöty on 430-530 miljoonaa, jos mökillä on ranta, jossa levistä ei ole haittaa. Häiritsevät leväkukinnot laskevat yhteenlaskettua virkistyshyötyä 30 miljoonalla ja rannattomuus 10-20 miljoonalla. Sähköistys nostaa yhteenlaskettua virkistyshyötyä 20-30 miljoonalla eurolla.

Innate Immune Recognition of RNA-virus infection in human macrophages

Innate immunity and host defence are rapidly evoked by structurally invariant molecular motifs common to microbial world, called pathogen associated molecular patterns (PAMPs). In addition to PAMPs, endogenous molecules released in response to inflammation and tissue damage, danger associated molecular patterns (DAMPs), are required for eliciting the response. The most important PAMPs of viruses are viral nucleic acids, their genome or its replication intermediates, whereas the identity and characteristics of virus infection-induced DAMPs are poorly defined. PAMPs and DAMPs engage a limited set of germ-line encoded pattern recognition receptors (PRRs) in immune and non-immune cells. Membrane-bound Toll-like receptors (TLRs), cytoplasmic retinoic acid inducible gene-I (RIG-I)-like receptors (RLRs) and nucleotide-binding oligomerization domain-like receptor (NLRs) are important PRRs involved in the recognition of the molecular signatures of viral infection, such as double-stranded ribonucleic acids (dsRNAs). Engagement of PRRs results in local and systemic innate immune responses which, when activated against viruses, evoke secretion of antiviral and pro-inflammatory cytokines, and programmed cell death i.e., apoptosis of the virus-infected cell. Macrophages are the central effector cells of innate immunity. They produce significant amounts of antiviral cytokines, called interferons (IFNs), and pro-inflammatory cytokines, such as interleukin (IL)-1β and IL-18. IL-1β and IL-18 are synthesized as inactive precursors, pro-IL-1β and pro-IL-18, that are processed by caspase-1 in a cytoplasmic multiprotein complex, called the inflammasome. After processing, these cytokines are biologically active and will be secreted. The signals and secretory routes that activate inflammasomes and the secretion of IL-1β and IL-18 during virus infections are poorly characterized. The main goal of this thesis was to characterize influenza A virus-induced innate immune responses and host-virus interactions in human primary macrophages during an infection. Methodologically, various techniques of cellular and molecular biology, as well as proteomic tools combined with bioinformatics, were utilized. Overall, the thesis provides interesting insights into inflammatory and antiviral innate immune responses, and has characterized host-virus interactions during influenza A virus-infection in human primary macrophages.

Svekofennialaisen orogenian ylityönnön terminen mallinnus Itä-Suomen arkeeisella kratonilla

This study reviews the thermophysical properties of rocks and the lithosphere and describes a one dimensional thermal numeric model of hypothetical 20 km thick overthrust plate obtruded on to the Archeaen craton in the Svecofennian orogeny (1.92-1.77 Ga). The objective is to find out if the overthrust plate and its radiogenic heat sources were able to produce the thermal effects observed on the current erosion level of the Archaean craton. Heat transfer in lithosphere is assumed conductive, and advective heat transfer due to melting and melt transfer is supposed negligible. The study area is located in the Eastern Finland, approximately current Kainuu and Northern Karelia regions, east from the most active orogenic belt (Raahe-Ladoga zone), so that orogenic magmatism can be neglected. Physical parameters and boundary conditions for the model are from different earlier published sources: deep seismic profiles (rock variation in depth), laboratory measurements (heat production and conductivity of rocks), field measurements (heat flow densities), and pT(t) estimations from the Finnish precambrian to estimate the size and thickness of the sheet. Comparison of the modelling results to previous K-Ar datings and other pTt estimations show, that the effect of the overthrust sheet has been adequate (max. T 450°C at 4 kbar) to produce the K-Ar resetting ages measured from the Archaean bedrock at current erosion level. No other kind of thermal activation in lithosphere is required. Results show possibly very minor partial melting in upper middle crust underneath the overthrust sheet.

Suomalaisen alkuperäiskarjan liha – kuluttajien osto- ja maksuhalukkuus

Tutkielman tavoitteena on selvittää suomalaisen alkuperäiskarjan lihan potentiaalista kysyntää. Alkuperäiskarjan lihan erikoistuotemarkkinat voivat auttaa pitämään uhanalaiset, kotimaiset karjarodut tuotantokäytössä. Näin ollen erikoistuotemarkkinat voivat auttaa arvokkaiden suomalaisten eläingeenivarojen säilyttämisessä. Koska alkuperäiskarjan lihan tuotannon kannattavuus riippuu lihasta saatavasta lisähinnasta, tutkimuksen tavoitteena on myös tutkia, millainen kuluttajien maksuhalukkuus alkuperäiskarjan lihasta on verrattuna tavanomaiseen lihaan. Tutkimusaineisto kerättiin Maa- ja elintarviketalouden tutkimuskeskuksen ja Kuluttajatutkimuskeskuksen suunnittelemalla kyselytutkimuksella keväällä 2010. Tutkimuksessa käytettiin ehdollisen käyttäytymisen ja ehdollisen arvottamisen menetelmiä ja sen otoskoko on 1623. Kuluttajien ostohalukkuutta ja siihen vaikuttavia tekijöitä tutkittiin sekä binäärisen että ordinaalisen regression malleilla. Kuluttajien maksuhalukkuutta alkuperäiskarjan lihasta ja siihen vaikuttavia tekijöitä tutkittiin grouped data -mallin avulla. Malleissa käytettiin selittävinä muuttujina sosioekonomisten muuttujien lisäksi kuluttajien asenteita ja käyttäytymistä kuvaavia muuttujia. Tutkielman tulosten mukaan jopa 86 % vastaajista ostaisi alkuperäiskarjan lihaa, jos sitä olisi tarjolla kaupoissa. Ostohalukkuutta lisää muun muassa, jos vastaajalla on alle 18-vuotiaita lapsia ja vastaaja arvostaa lähellä tuotettua, paikallista ruokaa sekä ympäristöystävällisyyttä. Miehet ostaisivat alkuperäiskarjan lihaa todennäköisemmin kuin naiset. Suurin osa vastaajista ostaisi alkuperäiskarjan lihaa, jos se olisi samanhintaista kuin tavanomainen liha, mutta noin neljäsosa (23,5 %) vastaajista olisi valmis maksamaan alkuperäiskarjan lihasta korkeampaa hintaa kuin tavanomaisesta lihasta. Maksuhalukkuuteen vaikuttivat positiivisesti muun muassa kuuluminen ympäristöjärjestöön ja korkea tulotaso. Negatiivisesti vaikutti puolestaan esimerkiksi se, että vastaaja on nainen. Keskimääräinen maksuhalukkuus alkuperäiskarjan lihasta oli 6,25 % korkeampi kuin tavanomaisesta lihasta. Maksuhalukkuus alkuperäiskarjan lihasta oli selvästi yhteydessä siihen, kuinka usein vastaaja olisi halukas ostamaan sitä. Maksuhalukkuus oli korkein niillä vastaajilla, jotka haluaisivat ostaa lihaa säännöllisesti.

REHTORIT PORTINVARTIJOINA : sekä miten rehtoreiden kertomuksista muodostuu pääkaupunkiseudun Tehostetun ja erityisen tuen kehittämisverkoston tarina

Research objectives. The Special Education Strategy, the legislative change based on it, and the change in the Finnish National Core Curriculum for Pre-primary and Basic Education build the background for this study. An improvement initiative called KELPO was founded in 2008 to implement a new three-level support system in municipalities. To support this initiative, the Network of Intensified and Special Support in the Metropolitan Area was founded in 2010. The Network consists of 22 pilot schools from four metropolitan municipalities and the Centre for Educational Assessment at the University of Helsinki that carries out the developmental assessment of the initiative. The objective of my study was to form an overall view of the functioning of the Network. The data included interviews of 20 principals of the schools belonging to the Network. The interviews were conducted by the Centre for Educational Assessment in the autumn of 2010. The research question is: What do principals speak about the networking done inside and between the municipalities? Methods. I received the data as already transcribed for my use. I researched it using a narrative research approach. As a method I used both thematic reading and classifying narratives by the holistic-content. These methods belong under the analyze of narratives. I collected the narratives from the principals under themes that arose from the data delimited by my research question. The narrative analysis materialized by writing the research story, as a new story was built by the principals stories theme by theme. The classification of the narratives by the holistic-content method was realized according to what kind of a gatekeeper s role each principal had. With a gatekeeper I here mean the intermediary role of a principal between the school and outside world. In addition, I used the analysis of interactive production of the narrative when applicable. Results and conclusions. Explicit features in the story of the Network were the principals at least partial uncertainty of the purpose of the networking, lack of time and resources, changing of initiatives, and lack of continuity. Positive narratives about ownership and empowerment could also be found. Nonetheless, many of the preconditions for success described by the school reform and school networking theories were not fulfilled. According to the collective story, there was no shared goal or purpose, and nor were the needs of autonomy, competence, and relatedness fulfilled. Three different kinds of gatekeepers were found in the data: The Exemplary ones, The Survivors and The Losers. The distinguishing factor turned out to be sharing of information at school. Based on the narratives, the schools with principals taking care of sharing information were the most active in partaking in networking.

Polymeereillä stabiloitu amorfinen formulaatio

Nowadays growing number of new active pharmaceutical ingredients (API) have large molecular weight and are hydrophobic. The energy of their crystal lattice is bigger and polarity has decreased. This leads to weakened solubility and dissolution rate of the drug. These properties can be enhanced for example by amorphization. Amorphous form has the best dissolution rate in the solid state. In the amorphous form drug molecules are randomly arranged, so the energy required to dissolve molecules is lower compared to the crystalline counterpart. The disadvantage of amorphous form is that it is unstable. Amorphous form tends to crystallize. Stability of amorphous form can be enhanced by adding an adjuvant to drug product. Adjuvant is usually a polymer. Polymers prevent crystallization both by forming bonds with API molecules and by steric hindrance. The key thing in stabilizing amorphous form is good miscibility between API and polymer. They have to be mixed in a molecular level so that the polymer is able to prevent crystallization. The aim of this work was to study miscibility of drug and polymer and stability of their dispersion with different analytical methods. Amorphous dispersions were made by rotary evaporator and freeze dryer. Amorphicity was confirmed with X-ray powder diffraction (XRPD) right after preparation. Itraconazole and theophylline were the chosen molecules to be stabilized. Itraconazole was expected to be easier and theophylline more difficult to stabilize. Itraconazole was stabilized with HPMC and theophylline was stabilized with PVP. Miscibility was studied with XRPD and differential scanning calorimetry (DSC). In addition it was studied with polarized light microscope if miscibility was possible to see visually. Dispersions were kept in stressed conditions and the crystallization was analyzed with XRPD. Stability was also examined with isothermal microcalorimetry (IMC). The dispersion of itraconazole and theophylline 40/60 (w/w) was completely miscible. It was proved by linear combination of XRPD results and single glass transition temperature in DSC. Homogenic well mixed film was observed with light microscope. Phase separation was observed with other compositions. Dispersions of theophylline and PVP mixed only partly. Stability of itraconazole dispersions were better than theophylline dispersions which were mixed poorer. So miscibility was important thing considering stability. The results from isothermal microcalorimetry were similar to results from conventional stability studies. Complementary analytical methods should be used when studying miscibility so that the results are more reliable. Light microscope is one method in addition to mostly used XRPD and DSC. Analyzing light microscope photos is quite subjective but it gives an idea of miscibility. Isothermal microcalorimetry can be one option for conventional stability studies. If right conditions can be made where the crystallization is not too fast, it may be possible to predict stability with isothermal microcalorimetry.

Cyclin dependent protein kinases as drug targets – potential in cardiovascular diseases

Complications of atherosclerosis such as myocardial infarction and stroke are the primary cause of death in Western societies. The development of atherosclerotic lesions is a complex process, including endothelial cell dysfunction, inflammation, extracellular matrix alteration and vascular smooth muscle cell (VSMC) proliferation and migration. Various cell cycle regulatory proteins control VSMC proliferation. Protein kinases called cyclin dependent kinases (CDKs) play a major role in regulation of cell cycle progression. At specific phases of the cell cycle, CDKs pair with cyclins to become catalytically active and phosphorylate numerous substrates contributing to cell cycle progression. CDKs are also regulated by cyclin dependent kinase inhibitors, activating and inhibitory phosphorylation, proteolysis and transcription factors. This tight regulation of cell cycle is essential; thus its deregulation is connected to the development of cancer and other proliferative disorders such as atherosclerosis and restenosis as well as neurodegenerative diseases. Proteins of the cell cycle provide potential and attractive targets for drug development. Consequently, various low molecular weight CDK inhibitors have been identified and are in clinical development. Tylophorine is a phenanthroindolizidine alkaloid, which has been shown to inhibit the growth of several human cancer cell lines. It was used in Ayurvedic medicine to treat inflammatory disorders. The aim of this study was to investigate the effect of tylophorine on human umbilical vein smooth muscle cell (HUVSMC) proliferation, cell cycle progression and the expression of various cell cycle regulatory proteins in order to confirm the findings made with tylophorine in rat cells. We used several methods to determine our hypothesis, including cell proliferation assay, western blot and flow cytometric cell cycle distribution analysis. We demonstrated by cell proliferation assay that tylophorine inhibits HUVSMC proliferation dose-dependently with an IC50 value of 164 nM ± 50. Western blot analysis was used to determine the effect of tylophorine on expression of cell cycle regulatory proteins. Tylophorine downregulates cyclin D1 and p21 expression levels. The results of tylophorine’s effect on phosphorylation sites of p53 were not consistent. More sensitive methods are required in order to completely determine this effect. We used flow cytometric cell cycle analysis to investigate whether tylophorine interferes with cell cycle progression and arrests cells in a specific cell cycle phase. Tylophorine was shown to induce the accumulation of asynchronized HUVSMCs in S phase. Tylophorine has a significant effect on cell cycle, but its role as cell cycle regulator in treatment of vascular proliferative diseases and cancer requires more experiments in vitro and in vivo.

2,1,3-Bentsoksadiatsolirakenteiset molekyylit antibakteerisina ja antiparasiittisina yhdisteinä

Aikaisemman tutkimuksen perusteella tiedettiin tiettyjen 2,1,3-bentsoksadiatsolirakenteisten molekyylien olevan aktiivisia Chlamydia pneumoniae –bakteeria vastaan. Tutkimusta lähdettiin jatkamaan ja 2,1,3-bentsoksadiatsolimolekyylien rakenne-aktiivisuusuhteista haluttiin saada lisätietoa. Tarkoituksena oli kehittää 2,1,3-bentsoksadiatsolimolekyyleille ja sen avulla muodostaa molekyylikirjasto. Syntetisoidut molekyylit haluttiin testata sekä Chlamydia pneumoniae -bakteeria että Leishmania donovani –parasiittia vastaan. Chlamydia pneumoniae –bakteeri aiheuttaa akuutteja ylä- ja alahengitystieinfektiota, kuten keuhkoputkentulehdusta. Akuutissa tulehduksessa oireet vaihtelevat huomattavasti. Chlamydia pneumoniae –bakteerilla on myös taipumus aiheuttaa kroonisia tulehduksia. Nämä ovat useissa tutkimuksissa yhdistetty kansantaloudellisesti merkittäviin sairauksiin, kuten ateroskleroosiin ja astmaan. Leishmanioosi on toiseksi yleisin loissairaus ihmisellä malarian jälkeen. Leishmania donovani –parasiitti voi aiheuttaa tappavaa viskeraalista leishmanioosia. Vuodessa leishmanioosiin kuolee yli 50 000 ihmistä. Viime vuosina leishmanioosin lääkehoidossa on esiintynyt monenlaisia ongelmia. Osat lääkkeistä ovat menettäneet tehonsa ja osalla esiintyy vakavia haittavaikutuksia. 2,1,3-Bentsoksadiatsolirakenteisille yhdisteille saatiin kehitettyä toimiva synteesireitti. Lähtöaineena käytettiin 4-amino-2-nitrobentsoehappoa, josta saatiin hapettavalla renkaansulkeutumisreaktiolla 2,1,3-bentsoksadiatsoli-5-karboksyylihappoa. Karboksyylihaposta syntetisoitiin amidi-välituotteen kautta 2,1,3-bentsoksadiatsoli-5-karbonitriiliä. Hydroksyyliamiini hydrokloridin avulla 2,1,3-bentsoksadiatsoli-5-karbonitriilistä muodostettiin vastaavaa karboksimidamidia, joka oli synteesireitin yhteinen välituote kaikille molekyyleille. Viimeisessä vaiheessa N´-hydroksidi-2,1,3-bentsoksadiatsoli-5-karboksimidamidin annettiin reagoida joko fenyyli-isosyanaatin tai fenyyli-isotiosyanaatin kanssa, jolloin saatiin lopputuotetta. Synteesireitin kehittäminen osoittautui haastavaksi ja loppujen lopuksi saatiin ainoastaan kolme lopputuotetta syntetisoitua. Yksi lopputuotteista testattiin C. pneumoniae –bakteeria vastaan Åbo akademissa Turussa. Testattavaa yhdiste ei sisältänyt 2,1,3-bentsoksadiatsoliarengasta ja bioaktiivisuuskokeen tulos oli odotusten mukainen. Yhdiste ei ollut aktiivinen C. pneumoniae –bakteeria vastaan alhaisilla konsentraatioilla ja tuloksesta voitiin todeta 2,1,3-bentsoksadiatsolirengaan olevan tärkeä aktiivisuuden kannalta. Kaksi lopputuotetta saatiin testaukseen Leishamania donovani –parasiittia vastaan Israeliin. Ainoastaan toinen molekyyleistä sisälsi 2,1,3-bentsoksadiatsolirakenteen. Bioaktiivisuuskokeiden tulokset olivat erittäin rohkaisevia. Yhdisteet olivat aktiivisia parasiittia vastaan jo alhaisilla konsentraatioilla. Kuitenkin 2,1,3-bentsoksadiatsolirakenteinen molekyyli oli aktiivisempi, joten tämäkin aktiivisuuskokeen perusteella huomattiin rengasrakenteen olevan tärkeä aktiivisuuden kannalta.

Protein Kinase C and Anaplastic Lymphoma Kinase Targeted Compounds

The protein kinases (PKs) belong to the largest single family of enzymes, phosphotransferases, which catalyze the phosphorylation of other enzymes and proteins and function primarily in signal transduction. Consequently, PKs regulate cell mechanisms such as growth, differentiation, and proliferation. Dysfunction of these cellular mechanisms may lead to cancer, a major predicament in health care. Even though there is a range of clinically available cancer-fighting drugs, increasing number of cancer cases and setbacks such as drug resistance, constantly keep cancer research active. At the commencement of this study an isophthalic acid derivative had been suggested to bind to the regulatory domain of protein kinase C (PKC). In order to investigate the biological effects and structure-activity relationships (SARs) of this new chemical entity, a library of compounds was synthesized. The best compounds induced apoptosis in human leukemia HL-60 cells and were not cytotoxic in Swiss 3T3 fibroblasts. In addition, the best apoptosis inducers were neither cytotoxic nor mutagenic. Furthermore, results from binding affinity assays of PKC isoforms revealed the pharmacophores of these isophthalic acid derivatives. The best inhibition constants of the tested compounds were measured to 210 nM for PKCα and to 530 nM for PKCδ. Among natural compounds targeting the regulatory domain of PKC, the target of bistramide A has been a matter of debate. It was initially found to activate PKCδ; however, actin was recently reported as the main target. In order to clarify and to further study the biological effects of bistramide A, the total syntheses of the natural compound and two isomers were performed. Biological assays of the compounds revealed accumulation of 4n polyploid cells as the primary mode of action and the compounds showed similar overall antiproliferative activities. However, each compound showed a distinct distribution of antimitotic effect presumably via actin binding, proapoptotic effect presumably via PKCδ, and pro-differentiation effect as evidenced by CD11b expression. Furthermore, it was shown that the antimitotic and proapoptotic effects of bistramide A were not secondary effects of actin binding but independent effects. The third aim in this study was to synthesize a library of a new class of urea-based type II inhibitors targeted at the kinase domain of anaplastic lymphoma kinase (ALK). The best compounds in this library showed IC50 values as low as 390 nM for ALK while the initial low cellular activities were successfully increased even by more than 70 times for NPM-ALK- positive BaF3 cells. More importantly, selective antiproliferative activity on ALK-positive cell lines was achieved; while the best compound affected the BaF3 and SU-DHL-1 cells with IC50 values of 0.5 and 0.8 μM, respectively, they were less toxic to the NPM-ALK-negative human leukemic cells U937 (IC50 = 3.2 μM) and BaF3 parental cells (IC50 = 5.4 μM). Furthermore, SAR studies of the synthesized compounds revealed functional groups and positions of the scaffold, which enhanced the enzymatic and cellular activities.

"Musiikki merkitsee minulle paljon" : Asennetutkimus musiikin opiskelun merkityksellisyydestä peruskoulun 9. luokkalaisille

The main purpose of the Master Thesis was to find out what kind of attitudes the pupils in the 9th grade of Finnish comprehensive school have towards music as a school subject and compare it to the attitudes of the principals at a school level. The theoretical context of the research is based on the former studies of the significance of music education in the comprehensive school, the connection between learning and attitudes and the motivational factors towards the study motivation of music. In addition to this, I have analysed the role of the evaluation and the assessment from the point of view of developing the educational system and what is the role of management and leadership in relation to the pupils` behaviour and attitudes. The data of the research is the Finnish National Board of Education`s collected data of the assessment of the learning outcomes of arts education and it is nationally representative (N=5056 I phase and n=1570 II phase), both the Finnish-language and the Swedish-language pupil data. I have especially concentrated on the items of measuring the attitudes, the certain background variables and the questionnaire of the principals. The numerical data was analyzed using the multivariate statistical methods. The results of the research prove that in general the pupils and the principals think that music is quite significant as a school subject. The girls valued music on average more than the boys when comparing all the dimensions. The differences were systematic but the effect sizes were under 10 %. There were not statistically significant differences between the Finnish-language and the Swedish-language pupils. Comparing the grades of music in the 7th grade, the differences were growing linearly and the effect size was 15.7 %. There was a positive statistically significant correlation between the Significance of music and music as a hobby (Active interest in music, Informal interest in music, Taking part of music activities in the school) during free time. The strongest correlation were with the Active interest in music variable (r= 0.53, p= .000). Also the principals thought that music is important as a school subject considering the development of the pupil and the function of the school. The answers of the pupils were not clustering at a school level and there were no strong correlations between the attitudes of the pupils and the principals. A statistically nearly significant and a slight correlation (r= 0.21, p= .011) was found between the principals valuing the Significance of the music for school function and the pupils valuing the Benefits and hobbyism. The role of a well-motivated and active music teacher can be important from this point of view. The most important conclusion of the research was that the significance of music is a very personal individual level phenomenon. The results highlight also that in the pupils` opinion the most important thing about music lessons is to musical activity and learning as an experience.
