Pitkittäistutkimus paluumuuttajien odotusten toteutumisen vaikutuksesta psykologiseen sopeutumiseen

Tutkimuksessa tarkasteltiin inkerinsuomalaisten muuttoa edeltävien odotusten toteutumisen yhteyttä psykologiseen sopeutumiseen. Psykologisen sopeutumisen indikaattorina käytettiin elämään tyytyväisyyttä. Tutkimuksen tavoitteena oli tuoda esille sopeutumista prosessina, joka alkaa jo ennen muuttoa (pre-akkulturaatio) sekä luoda uutta tietoa paluumuuttajien odotusten toteutumisen vaikutuksesta sopeutumiseen. Toteutuneiden odotusten tutkimuskenttä muodostaa oman tutkimusperinteensä, jonka piirissä on pyritty selvittämään odotusten ja kokemusten välisen suhteen yhteyttä tyytyväisyyteen eri konteksteissa. Akkulturaatiotutkimuksissa korostetaan, että maahanmuuttajien epärealistiset odotukset muuton jälkeisestä elämästä vaikeuttavat sopeutumisprosessia. Tässä pitkittäistutkimuksessa toteutuneiden odotusten yhteyttä elämään tyytyväisyyteen tarkasteltiin paluumuuttokontekstissa kolmen vaihtoehtoisen mallin avulla. Ideaalitaso-mallin mukaan odotusten toteutuminen nostaa elämään tyytyväisyyttä ja toteutumatta jääminen laskee sitä. Ei vahvistusta –mallissa elämään tyytyväisyyden oletetaan olevan korkeimmillaan silloin, kun kokemukset ylittävät odotukset. Vain kokemus –mallin mukaan hyvät kokemukset muuton jälkeen nostavat elämään tyytyväisyyttä odotusten tasosta riippumatta. Malleja testattiin erikseen sosio-psyykkiseen hyvinvointiin ja ammatillis-taloudelliseen hyvinvointiin liittyvien odotusten suhteen. Perhe- ja ystäväsuhteiden laadun sekä ammatillisten mahdollisuuksien ja taloudellisen tilanteen tason on osoitettu olevan yhteydessä elämään tyytyväisyyteen. Maahanmuuttajien odotuksien on niin ikään todettu koskevan näitä elämänlaatua indikoivia osa-alueita. Tutkimuksen aineisto koostui etniseltä taustaltaan inkerinsuomalaisista (N=141) paluumuuttajista. Lähtökohta-aineisto kerättiin Venäjällä ennen muuttoa ja seurantavaihe toteutettiin noin vuosi muuton jälkeen. Aineiston analysoinnissa huomioitiin ajankohtainen metodologiakeskustelu ja kahden muuttujan välisen suhteen vaikutusta riippuvaan muuttujaan tarkasteltiin polynomisen regressioanalyysin ja vastepintamallinnuksen avulla. Näin tehden voitiin välttää toteutuneiden odotusten tutkimuksille tyypilliset mittaus- ja metodologiaongelmat: retrospektiivisyys, erotuspistemäärien käyttö ja lineaaristen mallien käyttö. Tutkimuksen aineisto tuki ei vahvistusta –mallin mukaista yhteyttä odotusten toteutumisen ja elämään tyytyväisyyden välillä. Yhteyttä voitiin tarkastella vain sosio-psyykkiseen hyvinvointiin liittyvien odotusten ja kokemusten suhteen, koska ammatillis-taloudelliseen hyvinvointiin liittyvät odotukset, kokemukset tai niistä muodostetut interaktiotermit eivät polynomisen regressioanalyysin tulosten mukaan olleet yhteydessä elämään tyytyväisyyteen tilastollisesti merkitsevästi. Paluumuuttajien elämään tyytyväisyys oli korkeimmillaan silloin, kun sosio-psyykkiseen hyvinvointiin liittyvät kokemukset ylittivät odotukset. Odotusten ja kokemusten välisen eroavuuden suunnalla siis on tämän tutkimuksen tulosten perusteella merkitystä psykologisen sopeutumisen kannalta. Tutkimuksen tulos tukee näkemystä, jonka mukaan maahanmuuttajien sopeutumisprosessia tulisi tarkastella pitkittäisasetelmassa muuttoa edeltävä vaihe huomioiden. Lisäksi tutkimus avaa yhden näkökulman siihen, minkä elämän osa-alueiden laatu on paluumuuttajien sopeutumisen kannalta merkityksellistä.

Tämä pro gradu -tutkielma käsittelee kielisidonnaisen huumorin kääntämistä. Ennen itse kääntämisen käsittelyä täytyy kuitenkin määritellä mitä tarkoitetaan käsitteellä kielisidonnainen huumori . Aluksi käsitellään huumoria ja sen ominaisuuksia sekä huumorin ja kulttuuristen, fysiologisten ja sosiaalisten tekijöiden suhdetta. Huumori syntyy kun tietyt odotukset rikotaan, eli toimitaan joidenkin normien vastaisesti. Huumorin eräitä perusperiaatteita ovat ristiriitaisuus ja yhteensopimattomuus. Kielisidonnaisessa huumorissa ristiriitaisuus ja yhteensopimattomuus on havaittavissa kielen tasolla: kieltä käytetään tuottamaan moniselitteinen tai -mielinen koominen ilmaus. Sanaleikki, jossa käytetään yhtä sanaa jolla on yksi tai useampi merkitys, on tyypillinen esimerkki kielisidonnaisesta huumorista. Mutta kielisidonnainen huumori ei rajoitu pelkästään tämänkaltaisiin sanaleikkeihin (engl. pun), vaan kattaa käsitteenä laajemman valikoiman erilaisia kielisidonnaisen huumorin muotoja, esimerkiksi monimerkityksiset nimet, idiomaattisilla ilmauksilla tuotettu huumori, akrostikonit, kirjoituksen konventioita rikkomalla tuotettu huumori jne. Kielisidonnainen huumori on tutkielmassa luokiteltu ja määritelty omaksi huumorin alalajikseen. Kielisidonnaisen huumorin kielellinen monimerkityksisyys tekee sen kääntämisestä vaikeampaa kuin sellaisen tekstin, jossa kielen tasolla ei ilmene monimerkityksisyyttä. Tästä syystä kielisidonnainen huumori tarvitsee erilaisen käännösstrategian kuin esimerkiksi tieteellinen teksti. Seuraavaksi käydään aluksi läpi joitakin käännösteorian keskeisiä käsitteitä ja niiden suhdetta ja vaikutuksia kielisidonnaisen huumorin kääntämiseen. Sitten kuvataan kielisidonnaisen huumorin käännösprosessi, joka jakautuu kolmeen osaan: tunnistaminen, analyysi ja kääntäminen. Näiden kolmen pohjalta laaditaan kuuden eri käännösstrategian ryhmä. Kuusi eri päästrategiaa ovat käännössidonnaisen huumorikategorian säilyttäminen, kirjaimellinen käännös, muun tyylikeinon käyttäminen, kompensaatio, poisjättö ja toimitukselliset keinot. Strategiat käydään läpi deskriptiivisesti ja niiden käyttöä valaistaan esimerkkien avulla. Osa päästrategioista jakautuu alastrategioihin, jotka kuvaavat tarkemmin, minkälaisin keinoin lähtökielen kielisidonnainen käännösongelma voidaan siirtää kohdekieleen. Strategiat pyritään kuvaamaan siten, että ne voisivat olla avuksi käännettäessä minkä tahansa kieliparin välillä. Vaikka kuvatut käännösstrategiat käydään läpi deskriptiivisesti, on pyrkii tutkielma myös olemaan avuksi käytännön tilanteissa kielisidonnaista huumoria käännettäessä. Tätä varten on tutkielman lopussa annettu kuvaus yhden kielisidonnaisen huumoriongelman kääntämisprosessista. Yhdistämällä teoria käytäntöön kuvataan käännösprosessiesimerkissä yhden kielisidonnaisen huumoriongelman analyysi-ja kääntämisvaiheet. Tuloksena on viisi erilaista versiota samasta lähtötekstin käännösongelmasta. Tutkielma siis ensinnäkin määrittelee, mitä ja minkälaista on kielisidonnainen huumori sekä luokittelee sen. Toisekseen tutkielma kuvaa sen käännösprosessin ja määrittelee eri käännösstrategiat. Lisäksi esimerkin avulla esitellään eri käännösvaihtoehtoja. Avainsanat: kääntäminen, huumori, sanaleikki, kielisidonnainen

Kirjan tie lukijalle : Kirjakauppojen vakiintuminen Suomessa 1740 - 1860

Books Paths to Readers describes the history of the origins and consolidation of modern and open book stores in Finland 1740 1860. The thesis approaches the book trade as a part of a print culture. Instead of literary studies choice to concentrate on texts and writers, book history seeks to describe the print culture of a society and how the literary activities and societies interconnect. For book historians, printed works are creations of various individuals and groups: writers, printers, editors, book sellers, censors, critics and finally, readers. They all take part in the creation, delivery and interpretation of printed works. The study reveals the ways selling and distributing books have influenced the printed works and the literary and print culture. The research period 1740 1860 covers the so-called second revolution of the book, or the modernisation of the print culture. The thesis describes the history of 60 book stores and their 96 owners. The study concentrates on three themes: firstly, how the particular book trade network became a central institution for printed works distribution, secondly what were the relations between cosmopolitan European book markets and the national cultural sphere, and thirdly how book stores functioned as cultural institutions and business enterprises. Book stores that have a varied assortment and are targeted to all readers became the main institution for book trade in Finland during 1740 1860. It happened because of three features. First, the book binders monopoly on selling bound copies in Sweden was abolished in 1740s. As a consequence entrepreneurs could concentrate solely to trade activities and offer copies from various publishers at their stores. Secondly the common business model of bartering was replaced by selling copies for cash, first in the German book trade centre Leipzig in 1770s. The change intensified book markets activities and Finnish book stores foreign connections. Thirdly, after Finland was annexed to the Russian empire in 1809, the Grand duchy s administration steered foreign book trade to book stores (because of censorship demands). Up to 1830 s book stores were available only in Helsinki and Turku. During next ten years book stores opened in six regional centres. The early entrepreneurs ran usually vertical businesses consisting of printing, publishing and distribution activities. This strategy lowered costs, eased the delivery of printed works and helped to create elaborated centres for all book activities. These book stores main clientele consisted of the Swedish speaking gentry. During late 1840s various opinion leaders called for the development of a national Finnish print culture, and also book stores. As a result, during the five years before the beginning of the Crimean war (1853 1856) book stores were opened in almost all Finnish towns: at the beginning of the war 36 book stores operated in 21 towns. The later book sellers, mainly functioning in small towns among Finnish speaking people, settled usually strictly for selling activities. Book stores received most of their revenues from selling foreign titles. Swedish, German, French and Belgian (pirate editions of popular French novels) books were widely available for the multilingual gentry. Foreign titles and copies brought in most of the revenues. Censorship inspections or unfavourable custom fees would not limit the imports. Even if the local Finnish print production steadily rose, many copies, even titles, were never delivered via book stores. Only during the 1840 s and 1850 s the most advanced publishers would concentrate on creating publishing programmes and delivering their titles via book stores. Book sellers regulated commissions were small. They got even smaller because of large amounts of unsold copies, various and usual misunderstandings of consignments and accounts or plain accidents that destroyed shipments and warehouses. Also, the cultural aim of a creating large and assortments and the tendency of short selling periods demanded professional entrepreneurship, which many small town book sellers however lacked. In the midst of troublesome business efforts, co-operation and mutual concern of the book market s entrepreneurs were the key elements of the trade, although on local level book sellers would compete, sometimes even ferociously. The difficult circumstances (new censorship decree of 1850, Crimean war) and lack of entrepreneurship, experience and customers meant that half of the book stores opened in 1845 1860 was shut in less than five years. In 1858 the few leading publishers established The Finnish Book Publishers Association. Its first task was to create new business rules and manners for the book trade. The association s activities began to professionalise the whole network, but at the same time the earlier independence of regional publishing and selling enterprises diminished greatly. The consolidation of modern and open book store network in Finland is a history of a slow and complex development without clear signs of a beginning or an end. The ideal book store model was rarely accomplished in its all features. Nevertheless, book stores became the norm of the book trade. They managed to offer larger selections, reached larger clienteles and maintained constant activity better than any other book distribution model. In essential, the book stores methods have not changed up to present times.

Suomalaisten jääkiekkovalmentajien johtamiskäyttäytyminen

Tutkimuksen kohteena olivat jääkiekon valmentajakoulutukseen vuosina 1998 ja 1999 osallistuneet 30 valmentajaa. Valmentajien johtamistoimintaa arvioi yhteensä 245 pelaajaa ja lisäksi valmentajat arvioivat itse omaa johtamistoimintaansa. Menetelmänä käytettiin 360 asteen CPE (Change, Production, Employee)-johtamisarviota. Kuuden faktorin malli nousi tulkinnallisesti tarkoituksenmukaisimmaksi. Faktorit nimettiin seuraavasti: visiointi ja muutos, kontrolli, pelaajien positiivinen huomiointi, reiluus jaoikeudenmukaisuus, kehitys ja toimeenpano ja valmentava yksilöllinen ohjaus. Faktoreiden sisäinen konsistenssi vaihteli välillä .70 ja .80. Pelaajat arvioivat valmennuspäälliköt merkitsevästi valmentajia korkeammalla visiointi ja muutosfaktorilla, pelaajien positiivisessa huomioinnissa sekä kehitys ja toimeenpanofaktorilla. Korkeammin koulutetut arvioitiin myös korkeammallavisiointi ja muutosfaktorilla kuin vähemmän koulutusta saaneet. Jatkotarkastelua varten aineisto klusteroitiin ja klustereiden määräksi valittiin 5. Korkean profiilin valmentajat olivat itsearvioinneissaan varovaisempia, kun taas matalamman profiilin valmentajat olivat taipuvaisia itsensä yliarviointiin. Tulokset näyttäisivät tukevan käsitystä siitä, että johtaminen valmentamisessa on laadullisesti erilaista kuinjohtaminen työelämässä ja että valmentajan johtamistoiminnan arvioimiseen ei voida suoraan soveltaa työelämän tarpeisiin kehitettyjä mittareita. Valmennuskulttuurissa on vähitellen nostamassa päätään muutossuuntautunut ja ihmiskeskeisempi valmennuskulttuuri, jossa pelaajat nähdään enemmän kehityskykyisinä yksilöinä kuin kasvottomana pelaaja-materiaalina. Urheilu ei voi elää tyhjiössä, vaan ulkopuolisen maailman odotukset ja muutospaineet muuttavat väistämättä myös valmennuskulttuuria muun maailman kehityksen tahdissa.

From a "Student" to a Lifelong "Consumer" : Constructions of Educability in Adult Students' Narrative Life Histories

The focus of this study was to examine the constructions of the educable subject of the lifelong learning (LLL) narrative in the narrative life histories of adult students at general upper secondary school for adults (GUSSA). In this study lifelong learning has been defined as a cultural narrative on education, “a system of political thinking” that is not internally consistent, but has contradictory themes embedded within it (Billig et al., 1988). As earlier research has shown and this study also confirms, the LLL narrative creates differences between those who are included and those who fall behind and are excluded from the learning society ideal. Educability expresses socially constructed interpretations on who benefit from education and who should be educated and how. The presupposition in this study has been that contradictions between the LLL narrative and the so-called traditional constructions of educability are likely to be constructed as the former relies on the all-inclusive interpretation of educability and the latter on the meritocratic model of educating individuals based on their innate abilities. The school system continues to uphold the institutionalized ethos of educability that ranks students into the categories “bright”, “mediocre”, and “poor” (Räty & Snellman, 1998) on the basis of their abilities, including gender-related differences as well as differences based on social class. Traditional age-related norms also persist, for example general upper secondary education is normatively completed in youth and not in adulthood, and the formal learning context continues to outweigh both non-formal and informal learning. Moreover, in this study the construction of social differences in relation to educability and, thereafter unequal access to education has been examined in relation to age, social class, and gender. The biographical work of the research participants forms a peephole that permits the examination of the dilemmatic nature of the constructions of educability in this study. Formal general upper secondary education in adulthood is situated on the border between the traditional and the LLL narratives on educability: participation in GUSSA inevitably means that one’s ability and competence as a student and learner becomes reassessed through the assessment criteria maintained by schools, whereas according to the principles of LLL everyone is educable; everyone is encouraged to learn throughout their lives regardless of age, social class, or gender. This study is situated in the field of adult education, sociology of education, and social psychological research on educability, having also been informed by feminist studies. Moreover, this study contributes to narrative life history research combining the structural analysis of narratives (Labov & Waletzky, 1997), i.e. mini-stories within life history, with the analysis of the life histories as structural and thematic wholes and the creation of coherence in them; thus, permitting both micro and macro analyses. On accounting for the discontinuity created by participation in general upper secondary school study in adulthood and not normatively in youth, the GUSSA students construct coherence in relation to their ability and competence as students and learners. The seven case studies illuminate the social differences constructed in relation to educability, i.e. social class, gender, age, and the “new category of student and learner”. In the data of this study, i.e. 20 general upper secondary school adult graduates’ narrative life histories primarily generated through interviews, two main coherence patterns of the adult educable subject emerge. The first performance-oriented pattern displays qualities that are closely related to the principles of LLL. Contrary to the principles of lifewide learning, however, the documentation of one’s competence through formal qualifications outweighs non-formal and informal learning in preparation for future change and the competition for further education, professional careers, and higher social positions. The second flexible learning pattern calls into question the status of formal, especially theoretical and academically oriented education; inner development is seen as more important than such external signs of development — grades and certificates. Studying and learning is constructed as a hobby and as a means to a more satisfactory life as opposed to a socially and culturally valued serious occupation leading to further education and career development. Consequently, as a curious, active, and independent learner, this educable but not readily employable subject is pushed into the periphery of lifelong learning. These two coherence patterns of the adult educable subject illuminate who is to be educated and how. The educable and readily employable LLL subject is to participate in formal education in order to achieve qualifications for working life, whereas the educable but not employable subject may utilize lifewide learning for her/his own pleasure. Key words: adult education, general upper secondary school for adults, educability, lifelong learning, narrative life history

Yksi historia monimutkaistuvasssa maailmassa : Historian olemus ja historian suuret kertomukset luokanopettajaopiskelijoiden historiatietoisuudessa

One history in a multicomplex world The quintessence of history and grand historical narratives in the historical consciousness of class teacher students The study analyses the conception of history amongst class teacher students at the University of Helsinki. It also explores the expectations about the future that the students have on the basis of their views on history. The conceptions of the students are analysed against the background of the notion of one history which has been part of Western thought in the modern era and which is at the centre of the theoretical framework of this study. The Enlightenment project and the erosion of the role of the Church paved the way for the notion that history is an linear narrative of the progress of humankind and in which, implicitly, the Western countries are endowed with a special role as the vanguards of progress. In recent times these assumptions have been criticised by postmodernists and proponents of New History. The material of the study consists of interviews of twenty-two 19 26 years old class teacher students at the University of Helsinki. The topics in the interviews were the developments of the past and the future trajectories. The students conceived history as a field of knowledge that provides a unifying view on the world and helps to make today s world intelligible. Finnish history and global history were invested with features of a grand narrative of progress. In global history, progress and development were seen as characteristic of the Western world primarily. The students regarded the post-war Finnish history as a qualified success story in that they deplored the erosion of collectivist values and the rise of selfishness in recent decades. History was not conceived as a process of progress that would self-evidently continue in the future, but rather more as a field of contingency and cyclical change.The students regarded the increasing predominance of the market forces over democratically elected agencies, the antagonism between the West and the other parts of the world, and environmental risks as the major threats. Notwithstanding this general.pessimism about the future, the students had a very positive view of their own personal prospects. Keywords: historical consciouness, one history, future expectations

Kodin ja työn rajavyöhykkeellä - yhteensovittamisen jännitteitä ja ratkaisuja arjessa

The aim of this research is to study the boundary zone of home and work and the tensions people experience while reconciling home and work? How are the requirements of the family, the home and the work taken care of in everyday life? What kind of difficulties does the individual experience when reconciling home activities and job requirements together? What kind of activity policies have families created to ease the everyday life? What kind of goals and requirements do families feel behind the difficulties in adjusting home and work? What kind of changes would make the adjusting of home and work easier? The changing family life, everyday home activities and the changing Finnish working life are studied to describe the adjusting of home and work. In addition the boundary zone of home and work and its tensions are studied. 337 research persons who find reconciling home and work challenging were elected from different sectors of the working life. Research persons were gathered from the public, private and third sectors. The research material was gathered with a semi-structured qualitative questionnaire published in internet. Contents analysis was the analysis method of the research material. The tensions of adjusting home and work are various. Several activity systems meet on the boundary zone of home and work causing boundary zones to expand and tensions to increase and expand like a network. In the everyday life of an individual the boundary zone fades out and home and work overlap. Tensions can be examined as internal conflicts of the individual through the activity system of everyday life. Individuals balance between individualism and familism, feeling bad, suffering from lack of time and struggling with childcare organizing problems and inflexible employers. The solutions to reconciling home and work difficulties are situational. Often is the help of family and friends required without any solid solutions. The conflict of the goals, requirements and the reality is behind the problems as well as the tightening terms of the working life and its growing expectations. Change requests are proposed on the levels of individual, home, work and the society. Reconciling home and work is not only a challenge between the employee and the employer. It s a problem that needs multilateral solutions and changes on the levels of individual, home, work and society. The challenge remaining is to find out if it would be successful to take the everyday life as starting point to negotiate the reconciling of home and work and how the possible family, social and work political solutions appear in everyday life.

Neural stem cell characteristics affected by oncogenic pathways and in a human motoneuron disease

Neural stem cell characteristics affected by oncogenic pathways and in a human motoneuron disease Stem cells provide the self-renewing cell pool for developing or regenerating organs. The mechanisms underlying the decisions of a stem or progenitor cell to either self-renew and maintain multipotentiality or alternatively to differentiate are incompletely understood. In this thesis work, I have approached this question by investigating the role of the proto-oncogene Myc in the regulatory functions of neural progenitor cell (NPC) self-renewal, proliferation and differentiation. By using a retroviral transduction technique to create overexpression models in embryonic NPCs cultured as neurospheres, I show that activated levels of Myc increase NPC self-renewal. Furthermore, several mechanisms that regulate the activity of Myc were identified. Myc induced self-renewal is signalled through binding to the transcription factor Miz-1 as shown by the inhibited capacity of a Myc mutant (MycV394D), deficient in binding to Miz-1, to increase self-renewal in NPCs. Furthermore, overexpression of the newly identified proto-oncogene CIP2A recapitulates the effects of Myc overexpression in NPCs. Also the expression levels and in vivo expression patterns of Myc and CIP2A were linked together. CIP2A stabilizes Myc protein levels in several cancer types by inhibiting its degradation and our results suggest the same function for CIP2A in NPCs. Our results also support the conception of self-renewal and proliferation being two separately regulated cellular functions. Finally, I suggest that Myc regulates NPC self-renewal by influencing the way stem and progenitor cells react to the environmental cues that normally dictate the cellular identity of tissues containing self-renewing cells. Neurosphere cultures were also utilised in order to characterise functional defects in a human disease. Neural stem cell cultures obtained post-mortem from foetuses of lethal congenital contracture syndrome (LCCS) were used to reveal possible cell autonomous differentiation defects of patient NPCs. However, LCCS derived NPCs were able to differentiate normally in vitro although several transcriptional differences were identified by using microarray analysis. Proliferation rate of the patient NPCs was also increased as compared to NPCs of age-matched control foetuses.

Väkirehun määrän vaikutus lypsylehmän säilörehun syöntiin ja tuotokseen

Tämän tutkimuksen tarkoituksena oli selvittää väkirehumäärän vaikutuksia lypsylehmien säilörehun syöntiin ja syöntikäyttäytymiseen sekä tuotokseen lypsykauden alussa. Väkirehun määrän vaikutuksia on tutkittu paljon niukemmalla väkirehustuksella. Tilojen väkirehun osuus rehustuksessa saattaa ylittää jopa 60 %, joten on tärkeää selvittää väkevän rehustuksen vaikutusta lehmiin. Tutkimustietoa väkirehun määrän vaikutuksista säilörehupohjaisella ruokinnalla lypsykauden alussa on myös suhteellisen vähän. Koe suoritettiin Maa- ja elintarviketalouden tutkimuskeskuksessa (MTT) Jokioisissa Minkiön koenavetassa 20.9.2005 - 25.4.2006 välisenä aikana. Koe tehtiin pihaton osastossa, jossa oli säilörehun syöntiä mittaavat vaakakupit. Koe tehtiin jatkuvana ryhmäkokeena satunnaistetun koemallin mukaisesti. Koe-eläiminä oli 30 Ayshire-lehmää, joista 12 oli ensikoita ja 18 vanhempaa lehmää. Eläimet otettiin kokeeseen poikimisen jälkeen ja ne olivat mukana kokeessa 100 ensimmäisen lypsypäivän ajan. Kokeessa oli kaksi ryhmää eli matalan väkirehutason eläimet (MVR) sekä korkean väkirehutason eläimet (KVR). Vähemmän väkirehua saaneet eläimet saivat väkirehua 10 kg (ensikot) tai 13 kg (vanhemmat lehmät) päivässä. Väkevämmän ruokinnan ryhmässä vastaavat väkirehumäärät olivat 15 kg (ensikot) ja 18 kg (vanhemmat lehmät). Herutuksen kesto oli MVR-ryhmässä 11 vuorokautta ja KVR-ryhmässä 17 vuorokautta. Väkirehun määrän lisääminen vähensi säilörehun syöntiä, mutta lisäsi syönnin kokonaismäärää. Toteutuneet väkirehun osuudet kuiva-aineen syönnin kokonaismäärästä olivat 64 % (KVR) ja 52 % (MVR). Syönnin kokonaismäärä oli KVR-ryhmässä keskimäärin 2,1 kg kuiva-ainetta suurempi kuin MVR-ryhmässä. Säilörehun syönti oli MVR-ryhmässä keskimäärin 9,4 kg ka ja KVR-ryhmässä 7,9 kg ka. Korvaussuhde oli 0,41 kg ka säilörehua / kg ka väkirehua. Säilörehun syönnissä oli havaittavissa neljä syöntihuippua, eikä syönnin rytmittyminen poikennut juuri ryhmien välillä. Syöntihuiput tapahtuivat rehunjaon ja lypsyn jälkeen. Lisäksi keskiyöllä oli havaittavissa pienempi syöntihuippu. Enemmän väkirehua saaneet lehmät söivät säilörehua yhtä monta kertaa päivässä, mutta söivät numeerisesti nopeammin. Niiden yksittäinen syöntikerta oli lyhyempi ja sen aikana syöntimäärä oli pienempi kuin MVR-ryhmän eläimillä. Säilörehun syöntimäärä lisääntyi poikimisen jälkeen molemmissa ryhmissä, mutta määrän lisääntyminen tapahtui nopeammin vähemmän väkirehua saaneiden ryhmässä. Syöntimäärän lisääntyminen on selitettävissä kokonaissyöntiajan lisääntymisellä, sekä syöntiajan lisääntymisellä syöntikertaa kohden. Sitävastoin syöntinopeus hidastui lypsykauden edetessä. Tässä kokeessa ei saavutettu tuotosvastetta väkirehun määrää lisäämällä, vaikka rehun kokonaissyönti lisääntyi selvästi. Tuotosvaste oli vain 0,027 kg/kg ka väkirehua. Energiakorjattuna maitona ilmaistuna tuotosvaste oli negatiivinen eli - 0,22 EKM/kg ka. Huono tuotosvaste voi johtua tässä kokeessa väkirehun suuresta määrästä ja koostumuksesta. Suurempi kuiva-aineen syönti näytti kerryttävän KVR-ryhmän eläinten elopainoa maidontuotannon sijaan. Maidon rasva- ja valkuaispitoisuuksissa ei havaittu merkitseviä eroja ryhmien välillä, mutta pitoisuudet olivat pienempiä KVR-ryhmässä MVR-ryhmään verrattuna.

Describing and validating functional requirements as use cases

Requirements engineering is an important phase in software development where customer's needs and expectations are transformed into a software requirements specification. The requirements specification can be considered as an agreement between the customer and the developer where both parties agree on the expected system features and behaviour. However, requirements engineers must deal with a variety of issues that complicate the requirements process. The communication gap between the customer and the developers is among typical reasons for unsatisfactory requirements. In this thesis we study how the use case technique could be used in requirements engineering in bridging the communication gap between the customer and development team. We also discuss how a use case description can be use cases can be used as a basis for acceptance test cases.

Vahingonkorvaus kilpailunrajoituksen seuraamuksena kartellitapauksissa

Tutkielmassa on arvioitu kilpailuoikeudellista vahingonkorvausta kartellien aiheuttaman ylihintatilanteen seuraamuksena Suomen oikeusjärjestyksessä sekä tarvetta rangaistusluonteisin vahingonkorvauksiin. EU:n komissio haluaa lisätä vahingonkorvausten käyttöä kilpailunrajoitusten seuraamuksena ja on ehdottanut kaksinkertaisia vahingonkorvauksia kartellitapauksissa. Esikuvana on Yhdysvaltain kilpailuoikeudessa käytetty kolminkertainen vahingonkorvaus. Yhdysvalloissa vahingonkorvauksen reaaliarvo on kuitenkin epäedullisten korkosäännösten takia huomattavasti Suomea heikompi, ja kumpikin järjestelmä näyttää päätyvän jotakuinkin samanlaisiin lopputuloksiin. Tämä kyseenalaistaa tarpeen rangaistusluonteisten vahingonkorvausten käyttöönottoon Suomessa. Korvauksen määrää voidaan Suomessa ankaroittaa helpoimmin nykyisen viivästyskorkojärjestelmän puitteissa, sillä rangaistusluonteiset korvaukset olisivat periaatteellisesti erittäin suuri muutos Suomen oikeusjärjestykseen. Suomessa kilpailuoikeudellista vahingonkorvausta säännellään sopimusoikeudessa, vahingonkorvauslaissa ja kilpailunrajoituslaissa. Järjestelmä on jossain määrin hajanainen, mutta oikeudellisesti kattava. Yhdistettynä perusteettoman edun palautukseen ja ryhmäkanteeseen ei Suomen järjestelmään jää merkittäviä oikeudellisia aukkoja, mutta niiden soveltuvuus on toistaiseksi epäselvä. Järjestelmää voitaisiin kuitenkin parantaa tekemällä siitä yhtenäisempi, sillä tällä hetkellä se on varsin sirpaleinen. Suomen kilpailuoikeudellisen vahingonkorvausjärjestelmän suurin heikkous näyttää oikeussääntöjen puutteen sijasta olevan epävarmuus niiden tulkinnasta. Tämä näkyy selvästi niissä harvoissa oikeustapauksissa, jotka on käyty julkisesti, sillä ne ovat olleet erittäin riitaisia. Ankarampia seuraamuksia enemmän tarvitaankin oikeuskäytäntöä, varmuutta sääntöjen tulkinnasta ja laajempi tietoisuus mahdollisuudesta vahingonkorvauksiin kilpailunrajoituksista. Toinen merkittävä este vahingonkorvausten yleistymiselle ovat käytännön syyt, kuten vahingon vähäisyys suhteessa kanteen vaatimaan vaivaan ja kuluriskiin sekä vaikeudet näytön hankkimisessa. Niihin oikeussäännöillä on mahdollista vaikuttaa vain rajallisesti. Tässäkään rangaistusluonteisista vahingonkorvauksista ei ole juuri apua. Kilpailuoikeudellinen vahingonkorvaus voi parhaimmillaan olla merkittävä lisä julkisoikeudelliseen seuraamusjärjestelmään, ja tämän tutkielman perusteella Suomella on hyvät oikeudelliset edellytykset sen laajempaan käyttöön. Oikeuskäytäntöä tai lainsäädäntöä kuitenkin tarvitaan tulkinnanvaraisten kohtien selkiyttämiseksi, jotta vahingonkorvaus voi lunastaa siihen asetetut odotukset.

Dynamics of inflation expectations in the euro area

The present study examines empirically the inflation dynamics of the euro area. The focus of the analysis is on the role of expectations in the inflation process. In six articles we relax rationality assumption and proxy expectations directly using OECD forecasts or Consensus Economics survey data. In the first four articles we estimate alternative Phillips curve specifications and find evidence that inflation cannot instantaneously adjust to changes in expectations. A possible departure of expectations from rationality seems not to be powerful enough to totally explain the persistence of euro area inflation in the New Keynesian framework. When expectations are measured directly, the purely forward-looking New Keynesian Phillips curve is outperformed by the hybrid Phillips curve with an additional lagged inflation term and the New Classical Phillips curve with a lagged expectations term. The results suggest that the euro area inflation process has become more forward-looking in the recent years of low and stable inflation. Moreover, in low inflation countries, the inflation dynamics have been more forward-looking already since the late 1970s. We find evidence of substantial heterogeneity of inflation dynamics across the euro area countries. Real time data analysis suggests that in the euro area real time information matters most in the expectations term in the Phillips curve and that the balance of expectations formation is more forward- than backward-looking. Vector autoregressive (VAR) models of actual inflation, inflation expectations and the output gap are estimated in the last two articles.The VAR analysis indicates that inflation expectations, which are relatively persistent, have a significant effect on output. However,expectations seem to react to changes in both output and actual inflation, especially in the medium term. Overall, this study suggests that expectations play a central role in inflation dynamics, which should be taken into account in conducting monetary policy.

Individualized immunosuppression after renal transplantation in childhood

Pediatric renal transplantation (TX) has evolved greatly during the past few decades, and today TX is considered the standard care for children with end-stage renal disease. In Finland, 191 children had received renal transplants by October 2007, and 42% of them have already reached adulthood. Improvements in treatment of end-stage renal disease, surgical techniques, intensive care medicine, and in immunosuppressive therapy have paved the way to the current highly successful outcomes of pediatric transplantation. In children, the transplanted graft should last for decades, and normal growth and development should be guaranteed. These objectives set considerable requirements in optimizing and fine-tuning the post-operative therapy. Careful optimization of immunosuppressive therapy is crucial in protecting the graft against rejection, but also in protecting the patient against adverse effects of the medication. In the present study, the results of a retrospective investigation into individualized dosing of immunosuppresive medication, based on pharmacokinetic profiles, therapeutic drug monitoring, graft function and histology studies, and glucocorticoid biological activity determinations, are reported. Subgroups of a total of 178 patients, who received renal transplants in 1988 2006 were included in the study. The mean age at TX was 6.5 years, and approximately 26% of the patients were <2 years of age. The most common diagnosis leading to renal TX was congenital nephrosis of the Finnish type (NPHS1). Pediatric patients in Finland receive standard triple immunosuppression consisting of cyclosporine A (CsA), methylprednisolone (MP) and azathioprine (AZA) after renal TX. Optimal dosing of these agents is important to prevent rejections and preserve graft function in one hand, and to avoid the potentially serious adverse effects on the other hand. CsA has a narrow therapeutic window and individually variable pharmacokinetics. Therapeutic monitoring of CsA is, therefore, mandatory. Traditionally, CsA monitoring has been based on pre-dose trough levels (C0), but recent pharmacokinetic and clinical studies have revealed that the immunosuppressive effect may be related to diurnal CsA exposure and blood CsA concentration 0-4 hours after dosing. The two-hour post-dose concentration (C2) has proved a reliable surrogate marker of CsA exposure. Individual starting doses of CsA were analyzed in 65 patients. A recommended dose based on a pre-TX pharmacokinetic study was calculated for each patient by the pre-TX protocol. The predicted dose was clearly higher in the youngest children than in the older ones (22.9±10.4 and 10.5±5.1 mg/kg/d in patients <2 and >8 years of age, respectively). The actually administered oral doses of CsA were collected for three weeks after TX and compared to the pharmacokinetically predicted dose. After the TX, dosing of CsA was adjusted according to clinical parameters and blood CsA trough concentration. The pharmacokinetically predicted dose and patient age were the two significant parameters explaining post-TX doses of CsA. Accordingly, young children received significantly higher oral doses of CsA than the older ones. The correlation to the actually administered doses after TX was best in those patients, who had a predicted dose clearly higher or lower (> ±25%) than the average in their age-group. Due to the great individual variation in pharmacokinetics standardized dosing of CsA (based on body mass or surface area) may not be adequate. Pre-Tx profiles are helpful in determining suitable initial CsA doses. CsA monitoring based on trough and C2 concentrations was analyzed in 47 patients, who received renal transplants in 2001 2006. C0, C2 and experienced acute rejections were collected during the post-TX hospitalization, and also three months after TX when the first protocol core biopsy was obtained. The patients who remained rejection free had slightly higher C2 concentrations, especially very early after TX. However, after the first two weeks also the trough level was higher in the rejection-free patients than in those with acute rejections. Three months after TX the trough level was higher in patients with normal histology than in those with rejection changes in the routine biopsy. Monitoring of both the trough level and C2 may thus be warranted to guarantee sufficient peak concentration and baseline immunosuppression on one hand and to avoid over-exposure on the other hand. Controlling of rejection in the early months after transplantation is crucial as it may contribute to the development of long-term allograft nephropathy. Recently, it has become evident that immunoactivation fulfilling the histological criteria of acute rejection is possible in a well functioning graft with no clinical sings or laboratory perturbations. The influence of treatment of subclinical rejection, diagnosed in 3-month protocol biopsy, to graft function and histology 18 months after TX was analyzed in 22 patients and compared to 35 historical control patients. The incidence of subclinical rejection at three months was 43%, and the patients received a standard rejection treatment (a course of increased MP) and/or increased baseline immunosuppression, depending on the severity of rejection and graft function. Glomerular filtration rate (GFR) at 18 months was significantly better in the patients who were screened and treated for subclinical rejection in comparison to the historical patients (86.7±22.5 vs. 67.9±31.9 ml/min/1.73m2, respectively). The improvement was most remarkable in the youngest (<2 years) age group (94.1±11.0 vs. 67.9±26.8 ml/min/1.73m2). Histological findings of chronic allograft nephropathy were also more common in the historical patients in the 18-month protocol biopsy. All pediatric renal TX patients receive MP as a part of the baseline immunosuppression. Although the maintenance dose of MP is very low in the majority of the patients, the well-known steroid-related adverse affects are not uncommon. It has been shown in a previous study in Finnish pediatric TX patients that steroid exposure, measured as area under concentration-time curve (AUC), rather than the dose correlates with the adverse effects. In the present study, MP AUC was measured in sixteen stable maintenance patients, and a correlation with excess weight gain during 12 months after TX as well as with height deficit was found. A novel bioassay measuring the activation of glucocorticoid receptor dependent transcription cascade was also employed to assess the biological effect of MP. Glucocorticoid bioactivity was found to be related to the adverse effects, although the relationship was not as apparent as that with serum MP concentration. The findings in this study support individualized monitoring and adjustment of immunosuppression based on pharmacokinetics, graft function and histology. Pharmacokinetic profiles are helpful in estimating drug exposure and thus identifying the patients who might be at risk for excessive or insufficient immunosuppression. Individualized doses and monitoring of blood concentrations should definitely be employed with CsA, but possibly also with steroids. As an alternative to complete steroid withdrawal, individualized dosing based on drug exposure monitoring might help in avoiding the adverse effects. Early screening and treatment of subclinical immunoactivation is beneficial as it improves the prospects of good long-term graft function.

Immigration is one of the most topical international issues of our time. Worldwide, the number of immigrants has doubled over the last twenty years, and migration patterns have become so diversified that they now constitute a kind of “chaos”. The number and significance of women as migrants has also increased, which is earning women growing attention among scholars. This study looks at the migration of women, in particular mothers of small children, in both directions between Finland and Estonia, following the latter’s re- independence. The data consists of in-depth interviews conducted in 2005 with 24 Finnish and 24 Estonian immigrant women. The focus was on the women’s expectations and experiences of their new country of residence, acculturation – i.e. adjusting to a new environment, social networks in the country of origin and the new country, and models of motherhood following immigration. The primary research question was formulated as follows: Which factors have influenced the formation of female immigrants’ social ties, thus contributing to the formation of motherhood strategies and afecting internal family dynamics in the new country? The research consists of four previously published independent articles as well as a summary chapter. The study’s findings indicate that Finnish and Estonian women migrated for diferent reasons and at diferent times, and that their migration patterns also difered. Estonian migration occurred mainly in the 1990s, and most immigrants intended to return later to their country of origin. Regardless of the reason for migrating that they gave to immigration officials, other key reasons often included the desire for a more stable living environment and better income. Only four of the Estonian women had immigrated together with an Estonian husband, while two- thirds came because of marriage to a Finnish man. Most of the Finnish women, on the other hand, migrated after 2000 and either came with their family as a result of a spouse’s job transfer, or came by themselves to further their studies. In most cases, the migration was a temporary solution intended to promote one’s own or one’s spouse’s career advancement. Because the reasons for migrating were diferent between Finnish and Estonian women, their expectations of the new country and their status in it were also diferent. In terms of both social and economic standing, the position of Finnish immigrants was categorically better. The reason for migrating had an impact on one’s orientation toward the receiving society. Estonian women and Finns who migrated for marriage or edu cational reasons became immediately active in forming institutional and social ties in the new society. Conversely, the women had migrated because of work had little contact with Estonian society, and their social networks consisted of other Finnish immigrants. Furthermore, they maintained strong institutional and social ties to Finland and therefore felt no need to anchor themselves to Estonian society. The Finnish and Estonian women who were better integrated into the receiving country also maintained strong social ties to their country of origin. Women who became integrated into the receiving country as a result of giving birth to children utilized various services directed at families with children. In part, such services conveyed to the women the conceptions that were prevalent in the surrounding society concerning the treatment of children and the expectations on mothers, both of which difer to some extent in Finland and Estonia. had an impact on strategies of motherhood, internal family dynamics, and gender Regardless of the reason for migrating, or the country of origin, immigration equality. Most Estonian women had to do without the child-care help provided by relatives; before immigrating, some women had even had daily child-care assistance from family members. However, Estonian women who were married to Finns did receive help from the spouse and sometimes also the spouse’s relatives. Conversely, Finnish women who had immigrated because of a spouse’s job transfer were faced with the opposite situation, in which they bore the main responsibility for domestic work and child care. They were, however, in a position to pay for domestic help. Hence, the women who had integrated into a new society had to construct their own perceptions of motherhood by reconciling the motherhood models of both the cause of a spouse’s job transfer found that being a stay-at-home mother challenged previously self-evident behaviors. Receiving country and the country of origin, whereas women who had migrated because of a spouse’s job transfer found that being a stay-at-home mother challenged previously self-evident behaviors.
