Naton Kosovon-interventiolla vuonna 1999 ja Venäjän Georgian-interventiolla vuonna 2008 ei äkkiseltään katsottuna ole juurikaan yhteistä. Molemmissa tapauksissa kuitenkin suurempi valtio tai organisaatio toteutti sotilaallisen intervention suvereenin valtion fyysiselle alueelle ilman legitiimin kansainvälisen auktoriteetin, Yhdistyneiden kansakuntien turvallisuusneuvoston, siunausta. Molemmissa tapauksissa intervention kohteena oli monikulttuurinen, monien sosiaalisten, taloudellisten ja poliittisten jakolinjojen maa ja alue, jossa vähemmistöjen asema oli voimakkaan debatin aiheena. Tämän ”Pahaa hyvän puolesta?” -tutkielman tavoitteena on Yhdysvaltain ja Venäjän presidenttien puheissaan esittämien interventioiden oikeusperusteiden sekä niiden samankaltaisuuksien ja erojen määritteleminen. Tutkimuksen aineiston muodostavat presidentti Clintonin maalis-huhtikuussa 1999 ja presidentti Medvedevin elokuussa 2008 pitämät puheet, joissa he pyrkivät oikeuttamaan johtamaansa interventiota. Keskustelu Kosovon ja Georgian tapausten yhteneväisyyksistä heräsi syksyllä 2008: esimerkiksi pääministeri Vladimir Putin käytti Kosovon itsenäistymistä Georgian separatistialueiden itsenäistymisen esikuvana ja suomalaisten Venäjän-tutkijoiden piirissä interventioiden yhtäläisyyksiä pohdittiin jo pian Georgian tapahtumien alettua elokuussa 2008. Tähän keskusteluun haluan tällä tutkimuksella osallistua. Tutkimuksen teoreettinen tausta muodostuu valtiota, suvereniteettia, interventiota, sotaa, uhkaa ja identiteettiä käsittelevistä teorioista, Chaïm Perelmanin retoriikan teoriasta sekä aiemmasta Venäjän ja Yhdysvaltain ulkopolitiikkaa ja Georgiaa ja Kosovoa käsittelevästä tutkimuksesta. Aineiston analyysi osoittaa, että presidenttien esittämissä oikeusperusteissa oli sekä samankaltaisuuksia että eroavaisuuksia. Medvedevin esittelemät oikeutusperusteet voidaan jakaa neljään eri ryhmään, joita ovat kansainvälisen lainsäädännön rikkominen, humanitaariset syyt ja omien kansalaisten suojelu, rauhanturvaamisen ja historiallisen tehtävän täyttäminen sekä interventio rangaistuksena. Clintonin esittämät oikeutusperusteet jaan tässä tutkimuksessa viiteen ryhmään: interventio suuremman katastrofin estämiskeinona, humanitaarisen katastrofin, etnisen väkivallan ja julmuuden lopettamiskeinona, Yhdysvallat rauhantekijänä, vapaan, rauhallisen ja vakaan Euroopan puolesta sekä interventio moraalisena valintana ja vastauksena kansainvälisten sopimusten rikkomiselle. Puheissa esiintyy voimakkaita tunteisiin vetoavia ilmaisuja ja niissä on havaittavissa ajallinen evoluutio, ilmaisujen vähittäinen muuttuminen ajan kuluessa. Aineisto keskittyy erityisesti intervention alkuvaiheeseen, jolloin legitimiteetin vahvistaminen oli erityisen tärkeää. Molemmissa presidenttien puheissa uhka ja toiseus määritellään selkeästi. Oma toiminta esitetään korostetun positiivisessa valossa, viattomien pelastajana ja lain, oikeudenmukaisuuden ja turvallisuuden puolustajana. Puheet on suunnattu tarjoamaan jotain jokaiselle yleisölle. Poliittisina, virallisina dokumentteina niiden tehtävänä on vallankäyttö ja yleisöjen asenteisiin ja mielipiteisiin vaikuttaminen myös arvoihin vetoamalla. Puheet ovat viimeisteltyjä poliittisen teatterin näytöksiä. Näiden näytösten rooleja näyttelevät niin suuri valtio, pieni valtio, kansainvälinen yhteisö ja viattomien ihmisten kohtalokin.

At present the operating environment of sawmills in Europe is changing and there are uncertainties related in raw material supply in many countries. The changes in the operating environment of roundwood markets and the effects followed by these changes have brought up several interesting issues from the viewpoint of research. Lately new factors have been influencing the roundwood markets, such as increasing interest towards wood-based energy and implementation of new energy policies as well as changes in wood trade flows that affect the domestic markets in many countries. This Master’s thesis studies the adaptation ability of Finnish roundwood markets in a changing operating environment, aiming to produce an up-to-date analysis considering new development trends. The study concentrates on the roundwood markets from the viewpoint of sawmill industry since the industry is dependent on the functioning of the markets and sawmills are highly affected by the changes on the roundwood markets. To facilitate international comparison, the study is implemented by comparing Finnish and Austrian roundwood markets and analysing changes happening in the two countries. Finland and Austria share rather similar characteristics in the roundwood market structures, forest resources and forest ownership as well as production of roundwood and sawnwood. In addition they both are big exporters of forest industry products. In this study changes in the operating environment of sawmill industry both in Finland as well as in Austria are compared to each other aiming to recognise the main similarities and differences between the countries. In addition both development possibilities as well as challenges followed by the changes are discussed. The aim of the study is to define the main challenges and possibilities confronted by the actors on the markets and also to find new perspectives to approach these. The study is implemented as a qualitative study. The theoretical framework of the study describes the operating environment of wood markets from the viewpoint of the sawmill industry and represents the effects of supply and demand on the wood markets. The primary research material of the study was gathered by interviewing high level experts of forestry and sawmill industry in both Finland and Austria. The aim was to receive as extensive country specific viewpoint from the markets as possible, hence interviewees represented different parties of the markets. After creating country-specific profiles based on the theoretical framework a cross-country comparison was implemented. As a consequence the main similarities and differences in the operating environment and on the roundwood markets of Finland and Austria were recognized. In addition the main challenges and possibilites were identified. The results of the study offer a wide analysis regarding the main similarities and differences of the wood markets of Finland and Austria and their operating environments as well as concerning challenges and possibilities faced on the markets.

This study examines how sex education is currently developed and implemented in Greek primary schools. The four publications that comprise it explore the following themes: (1) the position and visibility of sex education as one of the topics for health education programme development; (2) the inhibiting and enhancing factors in the development and implementation of primary school sex education programmes; (3) how issues of sex, sexuality, the human body and romantic relationships are visually and textually represented in primary school textbooks; (4) the impact of sex education on teachers and pupils; and (5) teachers experiences as practitioners who deal with sexuality- related issues at school. -- The research was based on conducting multiple sub-studies using a mixed-methods approach. Specifically, qualitative and quantitative data were collected and analysed. The initial quantitative data that had been obtained by questionnaire was followed by the collection and analysis of qualitative data. The qualitative data were acquired by way of examining one particular case, various texts, interviews with teachers and self-reflective material. The results of the sub-studies are presented in a more detailed manner in the study s four publications. -- In general, the sub-studies found that sex education as an educational activity occupies a marginal place within the instructional practices of Greek primary school teachers, since the subject is hardly mentioned in classroom material, such as textbooks. However, engaging in the provision of sex education programmes can become a meaningful and rewarding experience for many teachers as well as pupils and their families. Further, teachers classroom experiences pointed to school settings as sexualized environments. These contextual factors and conditions nevertheless affected teachers practices and perceptions on a personal and professional level.Health indicators in Greece provide a picture of a population that faces various sexual health related problems. However, as many studies (including this work) indicate, sex education programmes that meet specific standards can have a positive impact on students overall health and well-being. Sex education teaching has always been a controversial issue. Its successful implementation in Greece demands knowledgeable educators and responsible policy-makers. The findings of this study suggest that the content of Greek primary school textbooks needs to be revised in order to include texts and pictures that deal with the human body and human sexuality, encourage pupils to become involved in designing the content and methods of programmes and give teachers the opportunity to reflect on and discuss their experiences.

Conflict, Unity, Oblivion: Commemoration of the Liberation War by the Civic Guard and the Veterans´ Union in 1918-1944 The Finnish Civil War ended in May 1918 as a victory for the white side. The war was named by the winners as the Liberation War and its legacy became a central theme for public commemorations during the interwar period. At the same time the experiences of the defeated were hindered from becoming a part of the official history of Finland. The commemoration of the war was related not only to the war experience but also to a national mission, which was seen fulfilled with the independence of Finland. Although the idea of the commemoration was to form a unifying non-political scene for the nation, the remembrance of the Liberation War rather continued than sought to reconcile to the conflict of 1918. The outbreak of the war between the Soviet Union and Finland in 1939 immediately affected the memory culture. The new myth of the Miracle of the Winter War, which referred to the unity shown by the people, required a marginalization of controversial memory of the Liberation War. This study examines from the concepts of public memory and narrative templates how the problematic experience of a civil war developed to a popular public commemoration. Instead of dealing with the manipulative and elite-centered grandiose commemoration projects, the study focuses on the more modest local level and emphasizes the significance of local memory agents and narrative templates of collective memory. The main subjects in the study are the Civil Guard and the Veterans´ Union. Essential for the widespread movement was the development of the Civic Guard from a wartime organization to a peacetime popular movement. The guards, who identified themselves trough the memories and the threats of civil war, formed a huge network of memory agents in every corner of the country. They effectively linked both local memory with official memory and the civic society with the state level. Only with the emergence of the right wing veteran movement in the 30ies did the tensions grow between the two levels of public memory. The study shows the diversity of the commemoration movement of the Liberation War. It was not only a result of a nation-state project and political propaganda, but also a way for local communities to identify and strengthen themselves in a time of political upheaval and uncertainty.

Higher education is faced with the challenge of strengthening students competencies for the constantly evolving technology-mediated practices of knowledge work. The knowledge creation approach to learning (Paavola et al., 2004; Hakkarainen et al., 2004) provides a theoretical tool to address learning and teaching organized around complex problems and the development of shared knowledge objects, such as reports, products, and new practices. As in professional work practices, it appears necessary to design sufficient open-endedness and complexity for students teamwork in order to generate unpredictable and both practically and epistemologically challenging situations. The studies of the thesis examine what kinds of practices are observed when student teams engage in knowledge creating inquiry processes, how the students themselves perceive the process, and how to facilitate inquiry with technology-mediation, tutoring, and pedagogical models. Overall, 20 student teams collaboration processes and productions were investigated in detail. This collaboration took place in teams or small groups of 3-6 students from multiple domain backgrounds. Two pedagogical models were employed to provide heuristic guidance for the inquiry processes: the progressive inquiry model and the distributed project model. Design-based research methodology was employed in combination with case study as the research design. Database materials from the courses virtual learning environment constituted the main body of data, with additional data from students self-reflections and student and teacher interviews. Study I examined the role of technology mediation and tutoring in directing students knowledge production in a progressive inquiry process. The research investigated how the scale of scaffolding related to the nature of knowledge produced and the deepening of the question explanation process. In Study II, the metaskills of knowledge-creating inquiry were explored as a challenge for higher education: metaskills refers to the individual, collective, and object-centered aspects of monitoring collaborative inquiry. Study III examined the design of two courses and how the elaboration of shared objects unfolded based on the two pedagogical models. Study IV examined how the arranged concept-development project for external customers promoted practices of distributed, partially virtual, project work, and how the students coped with the knowledge creation challenge. Overall, important indicators of knowledge creating inquiry were the following: new versions of knowledge objects and artifacts demonstrated a deepening inquiry process; and the various productions were co-created through iterations of negotiations, drafting, and versioning by the team members. Students faced challenges of establishing a collective commitment, devising practices to co-author and advance their reports, dealing with confusion, and managing culturally diverse teams. The progressive inquiry model, together with tutoring and technology, facilitated asking questions, generating explanations, and refocusing lines of inquiry. The involvement of the customers was observed to provide a strong motivation for the teams. On the evidence, providing team-specific guidance, exposing students to models of scientific argumentation and expert work practices, and furnishing templates for the intended products appear to be fruitful ways to enhance inquiry processes. At the institutional level, educators do well to explore ways of developing collaboration with external customers, public organizations or companies, and between educational units in order to enhance educational practices of knowledge creating inquiry.

This research is connected with an education development project for the four-year-long officer education program at the National Defence University. In this curriculum physics was studied in two alternative course plans namely scientific and general. Observations connected to the later one e.g. student feedback and learning outcome gave indications that action was needed to support the course. The reform work was focused on the production of aligned course related instructional material. The learning material project produced a customized textbook set for the students of the general basic physics course. The research adapts phases that are typical in Design Based Research (DBR). The research analyses the feature requirements for physics textbook aimed at a specific sector and frames supporting instructional material development, and summarizes the experiences gained in the learning material project when the selected frames have been applied. The quality of instructional material is an essential part of qualified teaching. The goal of instructional material customization is to increase the product's customer centric nature and to enhance its function as a support media for the learning process. Textbooks are still one of the core elements in physics teaching. The idea of a textbook will remain but the form and appearance may change according to the prevailing technology. The work deals with substance connected frames (demands of a physics textbook according to the PER-viewpoint, quality thinking in educational material development), frames of university pedagogy and instructional material production processes. A wide knowledge and understanding of different frames are useful in development work, if they are to be utilized to aid inspiration without limiting new reasoning and new kinds of models. Applying customization even in the frame utilization supports creative and situation aware design and diminishes the gap between theory and practice. Generally, physics teachers produce their own supplementary instructional material. Even though customization thinking is not unknown the threshold to produce an entire textbook might be high. Even though the observations here are from the general physics course at the NDU, the research gives tools also for development in other discipline related educational contexts. This research is an example of an instructional material development work together the questions it uncovers, and presents thoughts when textbook customization is rewarding. At the same time, the research aims to further creative customization thinking in instruction and development. Key words: Physics textbook, PER (Physics Education Research), Instructional quality, Customization, Creativity

Sulfotransferases (SULTs) and UDP-glucuronosyltransferases (UGTs) are important detoxification enzymes and they contribute to bioavailability and elimination of many drugs. SULT1A3 is an extrahepatic enzyme responsible for the sulfonation of dopamine, which is often used as its probe substrate. A new method for analyzing dopamine-3-O-sulfate and dopamine-4-O-sulfate by high-performance liquid chromatography was developed and the enzyme kinetic parameters for their formation were determined using purified recombinant human SULT1A3. The results show that SULT1A3 strongly favors the 3-hydroxy group of dopamine, which indicates that it may be the major enzyme responsible for the difference between the circulating levels of dopamine sulfates in human blood. All 19 known human UGTs were expressed as recombinant enzymes in baculovirus infected insect cells and their activities toward dopamine and estradiol were studied. UGT1A10 was identified as the only UGT capable of dopamine glucuronidation at a substantial level. The results were supported by studies with human intestinal and liver microsomes. The affinity was low indicating that UGT1A10 is not an important enzyme in dopamine metabolism in vivo. Despite the low affinity, dopamine is a potential new probe substrate for UGT1A10 due to its selectivity. Dopamine was used to study the importance of phenylalanines 90 and 93 in UGT1A10. The results revealed distinct effects that are dependent on differences in the size of the side chain and on the differences in their position within the protein. Examination of twelve mutants revealed lower activity in all of them. However, the enzyme kinetic studies of four mutants showed that their affinities were similar to that of UGT1A10 suggesting that F90 and F93 are not directly involved in dopamine binding in the active site. The glucuronidation of β-estradiol and epiestradiol (α-estradiol) was studied to elucidate how the orientation of the 17-OH group affects conjugation at the 3-OH or the 17-OH of either diastereomer. The results show that there are clear differences in the regio- and stereoselectivities of UGTs. The most active isoforms were UGT1A10 and UGT2B7 demonstrating opposite regioselectivity. The stereoselectivities of UGT2Bs were more complex than those of UGT1As. The amino acid sequences of the human UGTs 1A9 and 1A10 are 93% identical, yet there are large differences in their activity and substrate selectivity. Several mutants were constructed to identify the residues responsible for the activity differences. The results revealed that the residues between Leu86 and Tyr176 of UGT1A9 determine the differences between UGT1A9 and UGT1A10. Phe117 of UGT1A9 participated in 1-naphthol binding and the residues at positions 152 and 169 contributed to the higher glucuronidation rates of UGT1A10. In summary, the results emphasize that the substrate selectivities, including regio- and stereoselectivities, of UGTs are complex and they are controlled by many amino acids rather than one critical residue.

Tämän tutkimuksen tavoitteena oli tarkastella laadullisten tutkimuskeinojen avulla keskeisten tekijöiden etenkin palkitsemisen vaikutusta word-of-mouth -viestintään. Teoriakatsauksen perusteella tutkimusaluetta lähestyttiin tarkastelemalla viittä eri aihealuetta, suosittelijan sisäistä motivaatiota, kokemusta tuotteen tai palvelun ominaisuuksista, suhdetta yrityksen kanssa ja suosituksen vastaanottajan kanssa sekä palkitsemista ja suosittelukampanjaa. Tutkimuksen teoreettisessa osuudessa avattiin käsite word-of-mouth -viestintä ja suosittelumarkkinointi sekä selvitettiin word-of-mouth -viestintään vaikuttavia keskeisiä tekijöitä, jotta suosittelupäätökseen liittyviä tekijöitä olemassa olevan tutkimustiedon avulla. Empiirinen tutkimus toteutettiin laadullisena tutkimuksena, jossa tutkimuksen casena oli Agronomiliitto ry:n suosittelukampanja. Tutkimuksessa haastateltiin Helsingin yliopiston maatalous-metsätieteellisen tiedekunnan syksyn 2009 tutoreita koskien heille suunnattua jäsenhankintakampanjaa. Kampanjan tarkoituksena oli saada tutorit suosittelemaan Agronomiliiton jäsenyyttä uusille opiskelijoille. Parhaiten kampanjassa menestyneet tutorit palkittiin. Kahdeksasta haastateltavasta seitsemän oli Agronomiliiton jäseniä. Haastateltavista kolme palkittiin hyvästä menestyksestä kampanjassa. Aineistonkeruumenetelmänä käytettiin puolistrukturoitua ja henkilökohtaista teemahaastattelua. Haastatteluissa pyrittiin ennen kaikkea selvittämään haastateltavien ajatuksia liittyen word-of-mouth -viestintään sekä suosittelusta palkitsemiseen. Tutkimus antaa suuntaa, että sisäisellä motivaatiotekijöillä on suuri merkitys suositteluviestinnän tapahtumiselle. Suosittelijan tulee tunnistaa suositeltavasta tuotteesta tai palvelusta koetut hyödyt. Suosittelua myös edesauttaa jos suosittelija omaa mielipidejohtajan ominaisuuksia. Palkitseminen toimii kannustimena suositella, mutta palkitsemisjärjestelmä tulee miettiä huolellisesti, jotta suosittelija ei koe suosittelun vähentävän omaa tai suositteluviestin uskottavuutta. Tutkimuksen tulokset viittaavat molempien, suosittelijan ja suosittelun vastaanottajan palkitsemisen olevan paras palkitsemisjärjestelmä suosittelukampanjassa.

The study examines the personnel training and research activities carried out by the Organization and Methods Division of the Ministry of Finance and their becoming a part and parcel of the state administration in 1943-1971. The study is a combination of institutional and ideological historical research in recent history on adult education, using a constructionist approach. Material salient to the study comes from the files of the Organization and Methods Division in the National Archives, parliamentary documents, committee reports, and the magazines. The concentrated training and research activities arranged by the Organization and Methods Division, became a part and parcel of the state administration in the midst of controversial challenges and opportunities. They served to solve social problems which beset the state administration as well as contextual challenges besetting rationalization measures, and organizational challenges. The activities were also affected by a dependence on decision-makers, administrative units, and civil servants organizations, by different views on rationalization and the holistic nature of reforms, as well as by the formal theories that served as resources. It chose long-term projects which extended to the political decision-makers and administrative units turf, and which were intended to reform the structures of the state administration and to rationalize the practices of the administrative units. The crucial questions emerged in opposite pairs (a constitutional state vs. the ideology of an administratively governed state, a system of national boards vs. a system of government through ministries, efficiency of work vs. pleasantness of work, centralized vs. decentralized rationalization activities) which were not solvable problems but impossible questions with no ultimate answers. The aim and intent of the rationalization of the state administration (the reform of the central, provincial, and local governments) was to facilitate integrated management and to render a greater amount of work by approaching management procedures scientifically and by clarifying administrative instances and their respon-sibilities in regards to each other. The means resorted to were organizational studies and committee work. In the rationalization of office work and finance control, the idea was to effect savings in administrative costs and to pare down those costs as well as to rationalize and heighten those functions by developing the institution of work study practitioners in order to coordinate employer and employee relationships and benefits (the training of work study practitioners, work study, and a two-tier work study practitioner organization). A major part of the training meant teaching and implementing leadership skills in practice, which, in turn, meant that the learning environment was the genuine work community and efforts to change it. In office rationalization, the solution to regulate the relations between the employer and the employees was the co-existence of the technical and biological rationalization and the human resource administration and the accounting and planning systems at the turn of the 1960s and 1970s. The former were based on the school of scientific management and human relations, the latter on system thinking, which was a combination of the former two. In the rationalization of the state administration, efforts were made to find solutions to stabilize management ideologies and to arrange the relationships of administrative systems in administrative science - among other things, in the Hoover Committee and the Simon decision making theory, and, in the 1960s, in system thinking. Despite the development-related vocabulary, the practical work was advanced rationalization. It was said that the practical activities of both the state administration and the administrative units depended on professional managers who saw to production results and human relations. The pedagogic experts hired to develop training came up with a training system, based on the training-technological model where the training was made a function of its own. The State Training Center was established and the training office of the Organization and Methods Division became the leader and coordinator of personnel training.

Tutkimuksen tarkoituksena oli selvittää kuumetta vastaavan elinviljelylämpötilan vaikutusta hiiren poskihampaiden kiilteen kehittymiseen. Tutkimus tehtiin in vitro ja siinä käytettiin E18- hiiriä, joiden hampaita kasvatettiin ´kuumeessa´ (39 °C) kolmannesta kasvatuspäivästä lähtien, osaa viisi ja osaa kolme päivää. Kontrollihampaita kasvatettiin 37 °C:ssa. Hampaita kasvatettiin yhteensä 11 päivää ja lopuksi ne kuvattiin. Stereomikroskooppikuvista mitattiin kiilteen korkeus ja kruunun korkeus ja laskettiin näiden suhde. Hampaat demineralisoitiin, valettiin parafiiniin, leikattiin leikkeiksi ja värjättiin HE-värjäyksellä. Leikkeistä mitattiin kiilteen paksuus ja kiilteen ja dentiinin yhteispaksuus ja laskettiin näiden suhde. Arvoja verrattiin kasvatusryhmien kesken. Tulokset analysoitiin Mann-Whitney-testillä. Kiilteen paksuus suhteessa kiilteen ja dentiinin yhteispaksuuteen oli pienempi ´kuumehampaissa´. Viisi tai kolme päivää ´kuumeessa´kasvatettujen hampaiden välillä ei ollut juurikaan eroja. Kiilteen korkeus suhteessa kruunun korkeuteen oli pienempi ´kuumehampaissa´ kuin kontrollihampaissa. Korkea lämpötila ei muutoin näyttänyt vaikuttavan hampaiden kehitykseen. Tutkimuksen perusteella voidaan sanoa, että kasvatuslämpötilan nosto kuumeen tasolle aiheuttaa hiiren molaarihampaan kiilteen kehityksen häiriintymistä. Tulos tukee kliinisiä havaintoja, joiden mukaan korkea kuume lapsella voi aiheuttaa kiilteen kehityshäiriöitä.

Havupuiden erikoismuotoja on käytetty koristekasveina jo vuosisatoja ympäri maailmaa. Niitä on lisätty pääsääntöisesti pistokkaista ja varttamalla. Suomessa kotimaisten metsäpuidemme erikois-muotoja on kartoitettu ja kerätty kokoelmiin järjestelmällisemmin 1960-luvulta alkaen. Taimisto-viljelijät, puutarhasuunnittelijat ja kotipuutarhurit ovat olleet enenevässä määrin kiinnostuneita näistä kotimaisista kestävistä havukasveista. Yli 90 prosenttia markkinoillamme olevista havukas-veista tuodaan ulkomailta, joten on selvää, että niiden talvenkestävyydessä on ongelmia. Tämän tutkimuksen tavoitteena oli selvittää kotimaisille erikoismuodoille sopivia lisäysmene-telmiä ja siten edistää kotimaisen havukasvituotannon mahdollisuuksia. Aineistona kokeissa oli kotimaisia erikoismuotoja metsäkuusesta (Picea abies (L.) Karsten) ja kotikatajasta (Juniperus communis L.), tavallisia metsäkuusia sekä kahdeksan ulkomaista havupuutaksonia. Lisäysmene-telmistä tutkittiin varttamista ja pistokaslisäystä ja kokeet suoritettiin Metsäntutkimuslaitoksen toimipaikoissa Lopen Haapastensyrjässä sekä Punkaharjulla. Varttamiskokeessa vertailtiin koti-maisen kuusen erikoismuotokloonien varttamisen onnistumista. Pistokaskokeissa tutkittiin geno-tyypin, emopuun iän, pistokasoksan sijainnin sekä hormonikäsittelyn vaikutusta havukasvien pis-tokkaiden juurtumiseen. Tavalliset metsäkuuset toimivat kontrolleina. Tutkimus osoitti, että varttaminen onnistui erinomaisesti kaikilla erikoismuotoklooneilla. Ovat-ko vartteet esteettisesti katsottuna koristekäyttöön sopivia, jää vielä seurattavaksi. Pistokaskokeis-sa havaittiin, että juveniilisuus vaikutti pistokkaiden juurtumiseen, mutta iäkkäistäkin puista lisää-minen onnistuu, kunhan genotyyppi on sopiva. Keskimäärin alaoksat juurtuivat paremmin kuin latvuksen yläosista otetut pistokasoksat, mutta vain yhdellä kloonilla ero oli tilastollisesti merkit-sevä. Hormonikäsittely heikensi selvästi kotimaisen kuusen ja katajan pistokkaiden juurtumista, mutta ulkomaisiin havupuulajeihin käsittelyllä ei ollut vaikutusta. Kotimaisen havukasvituotannon pohjaksi pitäisi tehdä kloonivalintaa, jossa koristearvon lisäksi otettaisiin huomioon myös kloonin lisättävyys. Taimien tuottaminen pistokkaista on selvästi edul-lisempaa kuin vartteiden tuottaminen, joskin varte kasvaa myyntikuntoon nopeammin kuin pisto-kastaimi. Pistokastaimi on kuitenkin omajuurinen ja stabiilimpi kasvutavaltaan kuin varte. Tämä korostuu etenkin kääpiömuotoja tuotettaessa.

The subject matter of this study is the cultural knowledge concerning romantic male-female relationships in autobiographies written by so called ordinary Finnish men and women born between 1901 and 1965. The research data (98 autobiographies) is selected from two collections by the Finnish Literature Society s folklore archives in the early 1990 s. Autobiographies are cultural representations where negotiation of shared cultural models and personal meanings given to hetero-relationship is evident in an interesting manner. In this research I analyze autobiographies as a written folklore genre. Information concerning male-female relationships is being analyzed using theoretically informed close readings thematic analysis, intertextual reading and reflexive reading. Theoretical implications stem from cognitive anthropology (the idea of cultural models) and an adaptation of discourse theory inspired by Michel Foucault. The structure of the analysis follows the structure of the shared knowledge concerning romantic male-female relationship: the first phase of analysis presents the script of a hetero-relationship and then moves into the actual structure, the cultural model of a relationship. The components of the model of relationship are, as mentioned in the title of the research, woman, man, love and sex. The research shows that all the writers share this basic knowledge concerning a heterosexual relationship despite their age, background or gender. Also the conflicts described and experienced in the relationships of the writers were similar throughout the timespan of the early 1900 s to 1990 s: lack of love, inability to reconcile sexual desires, housework, sharing the responsibility of childcare and financial problems. The research claims that the conflicts in relationships are a major cause for the binary view on gender. When relationships are harmonious, there seems to be no need to see men and women as opposites. The research names five important discourses present in the meaning giving processes of autobiographers. In doing so, the stabile cultural model of male-female relationship widens to show the complexity and variation in data. In this way it is possible to detect some age and gender specific shifts and emphasis. The discourses give meaning to the components of the cultural model and determine the contents of womanhood, manhood, sexuality and love. The way these discourses are spread and their authority are different: the romantic discourse evident in the autobiographies appeal to the authority of love supreme love is the purpose of male-female relationship and it justifies sexuality. In this discourse sex can be the place for confluence of genders. The ideas of romantic love are widely spread in popular culture. Popular scientific discourse defines a relationship as a site to become a man and a woman either from a psychological or a biological point of view. Genders are seen as opposites. These ideas are often presented in media and their authority in science which is seen as infallible. The Christian discourse defines men and women: both should work for the benefit of the nuclear family under the undisputed authority of God. Marital love is based on Christian virtues and within marriage sexuality is acceptable. The discourse I ve named folk tradition defines women and men as guardians of home and offspring. The authority of folk tradition comes from universal truth based in experience and truths known to the mediators of this discourse grandparents, parents and other elders or peers. Societal discourse defines the hetero relationship as the mainstay of society. The authority in societal discourse stems from the laws and regulations that control relationship practices.

ABSTRACT Sense of coherence (SOC) is a core concept within Antonovsky s salutogenic theory and is argued to be a psychological determinant of health. The present social-epidemiological study explores the associations between a wide range of generalized resistance resources of SOC among Finnish- and Swedish-speaking women and men with a view to gaining deeper insight into its developmental circumstances and determinants. Secondly, a five-year follow-up study was conducted in order to assess the stability of SOC in difficult life events. Finally the role and effect of SOC in the intentions to retire early was investigated in a prospective study. The above studies were based on two data sets: the Finnish 'Survey on Living Conditions' (ELO-94) conducted in 1994 by means of personal face-to-face interviews (N=6506), and a prospective postal survey of the 15-year Health and Social Support (HeSSup) study for which the baseline data was collected in 1998 (N=25 898) and the follow-up in 2003. The present study reveals that the level of SOC in adulthood is strongly dependent on close and successful social relationships during both childhood and adulthood, and that there is a strong association with qualitative work features. Not having a partner as well as being unable to use one s skills at work proved to threaten men s SOC in particular, whereas a lack of social support did the same for women. Otherwise, the association with generalized resistance resources turned out to be quite similar in both genders. Swedish-speaking Finns appear to have a slightly stronger SOC due to the better psycho-emotional circumstances in the childhood home and work circumstances in adulthood, in other words higher levels of generalized resistance resources compared to Finnish speakers. These language group differences did not concern any social-life factors included in the present study. The results of the five-year follow-up study suggest that SOC is not stable, and that the level clearly decreases after a negative life event. Even a strong SOC decreased during the follow-up period and, furthermore, was no more stable than a mediocre or weak SOC. There seems to be a clear and independent association with the intentions to retire early among both men and women following full adjustment. Swedish speakers appear to be less inclined to retire early than Finnish speakers. In the light of the present study, it seems that SOC is determined not only by socio-economic factors but also by close and successful social relationships during both childhood and adulthood. This applied to both genders and language groups. Interventions aimed at promoting the health of the disadvantaged should therefore focus on families with children, and extend later also to other than socio-economic spheres of life. SOC theory could also be applied in efforts to inhibit early retirement: management practices aimed at providing employees with a work environment and tasks that are comprehensible, manageable and meaningful could potentially decrease the intentions to retire early.
