Kognitiva system i namngivningen av finländska handelsfartyg 1838-1938

This dissertation is an onomastic study of Finland s stock of ship names (nautonomasticon) recorded over the period 1838 1938. The primary material investigated consists of 2 066 examples of ship names from the fleets of coastal towns, distributed over five sample years. The material is supplemented with two bodies of comparative data; one that consists of 2 535 examples of boat names from the archipelago area at the corresponding time, and another that comprises 482 examples of eighteenth century Finnish ship names. This study clarifies the categories of names that appear the frequency of the names, formation, morphology, linguistic origin, functions, and semantic qualities. By comparing the material with boat names from previous centuries, and from other countries, the characteristics of Finnish vessel names are further highlighted. Additional clarification is brought to the chronological, regional, and social variations, and to the emergence of various forms of systematic naming. This dissertation builds on older research from other countries, and uses traditional onomastic methods alongside a more modern methodology. The approach is interdisciplinary, meaning that the names are explored using facts not only from nautical history, but also from a range of other historical disciplines such as economics, culture, art, and literature. In addition, the approach is socio-onomastic, i.e. that the variations in names are studied in a societal context. Using a synchronised perspective, cognitive linguistic theories have provided the tools for this exploration into the metaphorical and the prototypical meaning of the names, and the semantic domains that the names create. The quantitative analysis has revealed the overall picture of Finnish boat names. Personal names, names from mythology, and place names, emerge as significant categories, alongside nonproprial names in Swedish and Finnish. The interdisciplinary perspective has made it possible to explain certain trends in the stock of boat names, for example, the predisposition towards names from classical mythology, the breakthrough of names taken from the national epos Kalevala, names in the Finnish language from around the middle of the nineteenth century, and the continuing rise of place names during the latter part of the period 1838 1938. The socio-onomastic perspective has also identified clear differences between those ship names used in towns, and those ship names used in the archipelago, and it has clarified how naming conventions tend to spread from town centres to peripheral areas. The cognitive linguistic methods have revealed that the greater part of the vessel names can be interpreted as metaphors, in particular personifications, and that many names are related in their content and also form semantic networks and cognitive systems. The results indicate that there is a mental nautonomasticon that consists of a standard set of traditional ship names, but they also reveal the existence of conscious or unconscious cognitive systems (rules and conventions) that guide the naming of boats.

Lagöversättning som process och produkt : Revideringar och institutioner vid lagöversättning till svenska i Finland

The thesis studies the translation process for the laws of Finland as they are translated from Finnish into Swedish. The focus is on revision practices, norms and workplace procedures. The translation process studied covers three institutions and four revisions. In three separate studies the translation process is analyzed from the perspective of the translations, the institutions and the actors. The general theoretical framework is Descriptive Translation Studies. For the analysis of revisions made in versions of the Swedish translation of Finnish laws, a model is developed covering five grammatical categories (textual revisions, syntactic revisions, lexical revisions, morphological revisions and content revisions) and four norms (legal adequacy, correct translation, correct language and readability). A separate questionnaire-based study was carried out with translators and revisers at the three institutions. The results show that the number of revisions does not decrease during the translation process, and no division of labour can be seen at the different stages. This is somewhat surprising if the revision process is regarded as one of quality control. Instead, all revisers make revisions on every level of the text. Further, the revisions do not necessarily imply errors in the translations but are often the result of revisers following different norms for legal translation. The informal structure of the institutions and its impact on communication, visibility and workplace practices was studied from the perspective of organization theory. The results show weaknesses in the communicative situation, which affect the co-operation both between institutions and individuals. Individual attitudes towards norms and their relative authority also vary, in the sense that revisers largely prioritize legal adequacy whereas translators give linguistic norms a higher value. Further, multi-professional teamwork in the institutions studied shows a kind of teamwork based on individuals and institutions doing specific tasks with only little contact with others. This shows that the established definitions of teamwork, with people co-working in close contact with each other, cannot directly be applied to the workplace procedures in the translation process studied. Three new concepts are introduced: flerstegsrevidering (multi-stage revision), revideringskedja (revision chain) and normsyn (norm attitude). The study seeks to make a contribution to our knowledge of legal translation, translation processes, institutional translation, revision practices and translation norms for legal translation. Keywords: legal translation, translation of laws, institutional translation, revision, revision practices, norms, teamwork, organizational informal structure, translation process, translation sociology, multilingual.

Konstruktioner och valens : Verbfraser med åt i ett jämförande perspektiv

Det har knappast undgått någon som är språkligt medveten att finlandssvenskan och sverigesvenskan skiljer sig åt till vissa delar. Olikheterna återfinns på olika språkliga nivåer. Mest kända och omskrivna är de lexikologiska skillnaderna, dvs. skillnaderna på ordplanet. Betydligt mindre uppmärksamhet har ägnats syntaktiska skillnader, dvs. skillnader i hur satser och meningar byggs upp. För att öka kunskapen om finlandssvensk syntax initierade Språkvetenskapliga nämnden vid Svenska litteratursällskapet i Finland projektet Svenskan i Finland – syntaktiska drag i ett jämförande perspektiv, som pågick åren 2004–2006. Min avhandling har kommit till inom ramen för det projektet. Prepositionerna (t.ex. av, i, på, för, till, åt osv.) är så kallade funktionsord som har till uppgift att binda samman de mer betydelsetunga orden till satser och meningar. Den finlandssvenska prepositionsanvändningen skiljer sig i viss mån från den sverigesvenska, och ”åt” är en av de prepositioner som ofta lyfts fram som exempel. Finlandssvenskarna säger t.ex. ”han gav en bok åt Lena” i stället för ”han gav en bok till Lena” eller ”han gav Lena en bok”. De säger ”berätta något åt någon” (i stället för ”för”) och de säger ”ringa åt någon” i stället för ”ringa någon”. Ett huvudsyfte med min undersökning är att ta reda på hur pass stora skillnaderna är om man ser till samtliga belägg på ”åt” i ett material och inte bara till sådana som man fäster sig vid för att man vet att de avviker i finlandssvenskan. Undersökningen är korpusbaserad. Det betyder att jag letat efter alla belägg på kombinationer av verb och prepositionen ”åt” i rätt stora textmassor som finns tillgängliga i elektronisk form. Materialet ligger i Språkbanken i Finland och omfattar huvudsakligen tidningstext och skönlitteratur. Jag har använt mig av en textmassa på sammanlagt ungefär 40 miljoner löpande ord, drygt 23 miljoner finlandssvenska och drygt 19 miljoner sverigesvenska. Det materialet gav ca 20 000 åt-belägg att studera, och det visade sig något oväntat att ”åt” inte alls är vanligare i finlandssvenskan än i sverigesvenskan när det gäller skriftspråk, åtminstone inte i professionella skribenters språk. Om man kompenserar för att den finlandssvenska och den sverigesvenska korpusen inte är helt lika i fråga om genrefördelning och ålder, kommer man fram till i stort sett samma frekvens för ”åt” i båda korpusarna. För den närmare analysen av vilka mönster åt-beläggen uppvisar har jag först och främst utnyttjat konstruktionsgrammatik men också ramsemantik och valensteori. Konstruktionsgrammatiken är ingen enhetlig teori, men tanken om grammatiska konstruktioner är gemensam. Konstruktioner representerar allt från generella syntaktiska mönster till specifika mönster för språkliga enskildheter. Uppfattningen om vad som ska inbegripas i begreppet varierar, men definitionen av ”konstruktion” som ”par (eller konstellationer) av form och betydelse” är gemensam. ”Konstruktion” avser aldrig konkreta belägg i texter eller yttranden utan alltid det abstrakta mönstret bakom dessa. Och varje yttrande är resultatet av att en stor mängd konstruktioner samverkar. I min analys har jag utgått ifrån att beläggen med ”åt” kan återföras på olika konstruktioner eller mönster utifrån vad som är gemensamt för grupper av belägg. Jag har sett på vad åt-frasen i samverkan med verbet har för funktion i beläggen. En åt-fras är syntaktiskt en prepositionsfras och består av en preposition och en rektion. Exempelvis utgör ordparet ”åt skogen” en prepositionsfras där ”skogen” är rektion. Ur mitt material har jag kunnat abstrahera fram fem övergripande mönster där referenten för rektionen har olika så kallade semantiska roller. Åt-frasen kan i kombination med verbet ange mål eller riktmärke, som i t.ex. svänga åt höger, dra åt helvete, ta sig åt hjärtat, luta åt en seger för IFK. Den kan för det andra ange mottagare (t.ex. ge varsin kaka åt hundarna, bygga en bastu åt sina svärföräldrar, skaffa biljetter åt en kompis). För det tredje kan åt-frasen avse en referent som har nytta (eller skada) av en aktion (t.ex. klippa häcken åt grannen, ställa in digitalboxen åt sin moster). Åt-frasen kan slutligen avse den eller det som är föremål antingen för en kommunikationsaktion (vinka åt sin son, skratta åt eländet) eller en attityd eller känsla (glädja sig åt framgången). Utöver dessa huvudmönster finns det ett antal smärre grupper av belägg som bildar egna mönster, men de utgör sammanlagt under 3 % i bägge korpusarna. Inom grupperna kan undermönster urskiljas. I t.ex. mottagargruppen representerar ”ge varsin kaka åt hundarna” överföringskonstruktion, ”bygga en bastu åt sina svärföräldrar” produktionskonstruktion och ”skaffa biljetter åt en kompis” ombesörjningskonstruktion. Alla typer är gemensamma för bägge materialen, men andelen belägg som representerar de olika typerna skiljer sig betydligt. I det sverigesvenska materialet står t.ex. det mönster där åt-frasen avser mål eller riktmärke för en mycket större andel av beläggen än i finlandssvenskan. Också andelen belägg där åt-frasen avser någon som har nytta (eller skada) av en aktion är mycket högre i det sverigesvenska materialet. I det finlandssvenska materialet står i gengäld mottagarbeläggen för över 50 % av beläggen medan andelen i det sverigesvenska materialet är bara 30 %. Inom gruppen utgör belägg av produktions- och ombesörjningstyp dessutom en mindre andel i det finlandssvenska materialet än i det sverigesvenska. Dessa står till sin funktion nära den typ som avser den som har nytta av aktionen. De konkreta beläggen på överföring (ge varsin kaka åt hundarna) utgör en större andel i det finlandssvenska materialet än i det sverigesvenska (ca 8 % mot 3 %), men typiskt för båda materialen är hög kollokationsgrad (”kollokation” avser par eller grupper av ord som uppträder oftare tillsammans än de statiskt sett skulle göra vid helt slumpmässig förekomst). Största delen av mottagarbeläggen utgörs av fraser av typen ”ge arbete åt någon, ge eftertryck åt något, ge liv åt något; ägna tid åt något, ägna sitt liv åt något, ägna uppmärksamhet åt något”. De här slutsatserna gäller alltså skriftspråk. I talspråk ser fördelningen annorlunda ut. Typiskt för prepositionen ”åt” är överhuvudtaget hög kollokationsgrad. Det förefaller som om språkanvändarna har tydliga, färdiga mallar för var ”åt” kan komma in. Det enda mönster som verkar helt produktivt, i den meningen att elementen är i stort sett fritt kombinerbara, är kombinationer av verb och åt-fras där åt-frasen avser den som har nytta av något. Att någon utför något för någons räkning verkar överlag kunna uttryckas med prepositionen ”åt”: t.ex. ”tvätta bilen åt pappa, ringa efter en taxi åt kunden”. Till och med belägg av typen ”hon drömde åt honom att bli ordinarie adjunkt” förekommer i någon mån. Konstruktionen är produktiv i båda språkvarieteterna men uppenbart är att konstruktion med mottagare har tolkningsföreträde i vissa fall i finlandssvenskan: ”Filip skrev ett brev åt sin syster” tolkas av sverigesvenskar som att Filip skrev brevet för systerns räkning, medan finlandssvenskar överlag uppenbarligen tolkar det som att Filip skrev till sin syster, att systern var mottagare av brevet. Ungefär 20 % av alla belägg i båda materialen representerar fall där ”åt” utgör partikel. Verb och ”åt” är närmare förbundna med varandra än när ”åt” utgör normal preposition. Exempel på partikelbelägg är ”han kom inte åt strömbrytaren, det gick åt mängder med saft, landet får dra åt svångremmen, de roffade åt sig de bästa platserna”. Också partikelmaterialet ser på ett generellt plan väldigt lika ut i båda språkvarieteterna. Den största skillnaden uppvisar den reflexiva typen ”roffa åt sig”. Medan typen är mycket homogen i det sverigesvenska materialet är variationen större i det finlandsvenska. Dels uppträder fler verb i kombinationen (han köpte åt sig ett par jeans), dels vacklar ordföljden (han nappade åt sig ett paraply ~ han nappade ett paraply åt sig). Att ”åt” används mer i vissa funktioner i finlandsvenskan brukar förklaras med påverkan från finskans allativ (ändelsen -lle: hän antoi kirjan Astalle > hon gav en bok åt Asta). Allt tyder dock på att den finlandssvenska åt-användningen delvis är en relikt. I äldre sverigesvenska källor träffar man på ”åt” i sådana kontexter som numera är typiska för finlandsvenskan. Det finlandssvenska språkområdet ligger ute i periferin i relation till det språkliga centrum som förändringar sprider sig från (för svenskans del främst Stockholmstrakten) och typiskt för perifera områden är att de uppvisar ålderdomliga drag också när inga kontaktfenomen spelar in. Allativen kan naturligtvis ha bidragit till att bevara användningen av ”åt” i finlandssvenskan. Att det är just ”åt” som används” beror antagligen på att prepositionen har flest funktioner gemensamt med allativen rent kognitivt om man jämför med de betydligt mer frekventa prepositionerna ”till” och ”för”. Uppenbart är också att åt-användningen därtill lever sitt eget liv i finlandssvenskan. I vissa varieteter av finlandssvenska kan man t.ex. höra yttranden av typ ”alla fiskarna dog åt dom”. Som språklig enskildhet har det ingen finsk förebild med allativ. Yttrandet är ett exempel på töjning av en svensk konstruktion. Modell finns dels i det mönster där åt avser den som har nytta eller skada av något, dels i relationell användning av ”åt”: han är hantlangare åt Eriksson ~ han är Erikssons hantlangare. Vid språkkontakt är det överlag konstruktioner som har förebild i det låntagande språket som lånas in från det långivande språket, medan konstruktioner som saknar förebild är betydligt mindre benägna att vinna insteg.

Konstruktioner i interaktion. : de e som resurs i samtal

This study concerns the most common word pair in spoken Swedish, de e (it is, third person pronoun + copula-verb in present tense). The aim of the study is twofold, with an empirical aim and a theoretical aim. The empirical aim is to investigate if and how the string de e can be understood and described as a construction in its own right with characteristics that distinguishes it from other structures and resources in spoken Swedish. The theoretical aim is to test how two different linguistic theories and methods, interactional linguistics and construction grammar, can be combined and used to describe and explain patterns in languaging that traditional grammar does take into account. The empirical analysis is done within the interactional linguistic framework with sequence analyses of excerpts from authentic conversation data. The data consists of approximately ten hours of recorded conversation from Finland and Sweden. The sequence analysis suggests that the string de e really is used as a resource in its own right. In most cases, the string is also used in ways consistent with abstract grammatical patterns described by traditional grammar. Nevertheless, there are instances where de e is used in ways not described before: with numerals and infinitive phrases as complements, without any complements at all and together with certain complements (bra, de) in idiomatic ways. Furthermore, in the instances where de e is used according to known grammatical patterns the function of the particular string de e is clearly contextually specific and in various ways linked to the micro-context in which it is used. A new model is suggested for understanding and concluding the results from the sequence analyses. It consists of two different types of constructions grammatical and interactional. The grammatical constructions show how the string is used in eleven structurally different ways. The interactional constructions show seven different sequential positions and functions in which the string occurs. The two types of constructions are also linked to each other as potentials. This is a new way to describe how interactants use and responds to a concrete string like de e in conversation.

Kampen om Eros : Om kön och kärlek i Pahlensviten

The Struggle for Eros: On Love and Gender in the Pahlen Series The present dissertation examines how gender, sexuality and motherhood are constructed in the novel series Fröknarna von Pahlen (The Misses von Pahlen, I VII, 1930 1935) by the Swedish author Agnes von Krusenstjerna. The aim of the study is to analyze how the Pahlen series relates to the discourses on gender and sexuality circulating in the 1930s, and how the series opens a dialogue with the feminist thinking of the time especially with the book Lifslinjer I (Love and Marriage, 1903) by the Swedish author Ellen Key. Fröknarna von Pahlen holds a central position in the research on Agnes von Krusenstjerna partly due to the literary debate that the novel series triggered. The debate was connected to the development taking place in the Swedish society in the beginning of the 1930s, in the so-called second phase of the Modern Breakthrough. Sweden was at that time characterized by struggle over the definitions of gender, sexuality and parenthood, and this struggle is also visible in the Pahlen series. The literary debate took place in 1934 1935 and it began after an article by the modernist writer Karin Boye was published in Social-Demokraten on 28 January 1934. In her polemic article, Boye saw the Pahlen series as a sign that the family institution is on the verge of a breakdown and with it the whole moral system that has come to existence through it . Boye went on to state that Krusenstjerna only sees and describes and that she explores neither new literary forms nor new values. Boye wrote the article before the last two parts of the novel series were published, so obviously she could not discuss the utopian vision characterizing those parts. This study, however, strives to demonstrate that Krusenstjerna not only sees and describes, but that she like many of her contemporary female colleagues appears to take the request of Friedrich Nietzsche to revaluate all values seriously. Like the works of her contemporaries, Krusenstjerna s Pahlen series is marked by a double vision on the one hand a critique of the prevailing social order, and on the other hand a dream of a new world and a new human being. In this research the vision of the Pahlen series is characterized as queer in order to emphasize that the series not only criticizes the prevailing gender order and its morals, but is also open for new ways of doing gender, parenthood, and family.

Det pedagogiska självet : en narrativ studie av direktvalda svensklärarstudenters berättelser

The Pedagogical Self: a narrative study of stories by prospective subject teachers of Swedish The aim of this study is to examine how prospective subject teachers of Swedish experience themselves, their lives and their studies in university context. By answering this question I try to shed light on the pedagogical self of the students, i.e. to reach a deeper understanding of the narrative construction of their teacher identity. My material consists of stories written by one group of students and of transcribed interviews with another group of students at Nordica. All these students have entered both the teacher education programme and studies in their major subject simultaneously, through the so called direct admission. My study focuses on the students first year at the university. I define teacher identity, the pedagogical self, as the part of an individual s self-concept where he/she makes an assessment of himself/herself as a teacher(-to-be). The frame of reference of this interdisciplinary narrative study is founded on phenomenology, hermeneutics, social constructionism and dialogism. The main analysis of the stories is thematic, with the addition of linguistic and metaphorical analysis. With reference to the theories of Paul Ricoeur and Katharine Young, I regard the textual world of the stories as a world of its own. This implies that the researcher can feel free to concentrate on the texts, thus being able to leave the mental processes of the writers disregarded. The theoretician that has influenced my research the most is Max van Manen. He combines a pedagogical attitude with a phenomenological-hermeneutic philosophy. My research results imply that most of these students are drawn to studying Swedish by the clear professional orientation of the studies; their identity as teachers seems to be stronger than their identity as language teachers. The image of a teacher is relatively traditional: a teacher is seen as a self-evident authority, but at the same time as a fostering educator. The students see their studies in a larger perspective: studies as well as the future profession are only one part of life, albeit an important one. Keywords: narrativity, teacher identity

My Fair Lady på skandinaviska : En studie i funktionell sångöversättning

The dissertation presents a functional model for analysis of song translation. The model is developed on the basis of an examination of theatrical songs and a comparison of three translations: the songs of the Broadway musical My Fair Lady (Lerner and Loewe, 1956), made for the premiere productions (1959–1960) in Swedish, Danish, and Norwegian. The analysis explores the three challenges of a song translator: the fitting of a text to existing music, the consideration of a prospective sung performance, and the verbal approximation of the content of the source lyric. The theoretical foundation is based on a functional approach to translation studies (Christiane Nord) and a structuralist/semiotic analysis of a theatrical message (Ivo Osolsobě, building on Roman Jakobson). Thus, three functional levels in the fitting of a text to music are explored: first, a prosodic/phonetic format; secondly, a poetic/rhetoric format; and thirdly, semantic/reflexive values (verbalizing musical expression). Similarly, three functional levels in the textual connections to a prospective performance are explored: first, a presentational goal; secondly, the theatrical potential; and thirdly, dramaturgic values (for example dramatic information and linguistic register). The functionality of Broadway musical theatre songs is analyzed, and the song score of My Fair Lady, source and target lyrics, is studied, with an in-depth analysis of seven of the songs. The three translations were all considered very well-made and are used in productions of the musical to this day. The study finds that the song translators appear to have worked from an understanding of the presentational goal, designed their target texts on the prosodic and poetic shape of the music, and pursued the theatrical functionality of the song, not by copying, but by recreating connections to relevant contexts, partly independently of the source lyrics, using the resources of the target languages. Besides metaphrases (closest possible transfer), paraphrases and additions seem normally to be expected in song translation, but song translators may also follow highly individual strategies – for example, the Norwegian translator is consistently more verbally faithful than the Danish and Swedish translators. As a conclusion, it is suggested that although linguistic and cultural difference play a significant role, a translator’s solution must nevertheless be arrived at, and assessed, in relation to the song as a multimedial piece of material. As far as a song can be considered a theatrical message – singers representing the voice, person, and situation of the song – the descriptive model presented in the study is also applicable to the translation of other types of song.

Konstteoretikern och livet : Mikael Lybecks Breven till Cecilia i nietzscheansk belysning

I avhandlingen analyseras den finlandssvenska författaren Mikael Lybecks (1864-1925) verk Breven till Cecilia. Denna brevroman hör till Lybecks senare produktion och utkom 1920. Verket har kommit att betraktas som en klassiker inom den finlandssvenska litteraturen. Av författarensövriga produktion är det strängt taget endast Tomas Indal (1911) som haft en jämförbar genomslagskraft. Trots detta har romanen inte varit föremål för en enda mer omfattande studie. l sin Lybeckbiografi relaterar Erik Kihlman i första hand verket till det biografiska och till samhällssituationen vid tiden för romanens tillkomst. Vetenskapen, konsten och livet bildar tillsammans den triangel som utgör romanens stomme. Antiken är starkt närvarande i romanen och med begrepp som härrör från denna era kan man tala om det sokratiska, det apollinska och det dionysiska. Detta är begrepp som Friedrich Nietzsche utgår i från i sitt ungdomsverk Tragedins födelse (Die Geburt der Tragödie aus dem Geiste der Musik) från 1872. Nietzsches vetenskapskritik och hans syn på den högsta konsten som ett brödraförbund mellan Dionysos och Apollon står i förvånansvärt hög grad i samklang med den övergripande tematiken i Lybecks verk. När Nietzsche därtill framhäver musiken som grunden förall konst får många inslag i romanen sin förklaring. l Breven till Cecilia skildras en vändpunkt i huvudpersonen Sven Ingelets liv. Därför ligger tyngdpunkten i den tematiska analysen vid det som gör att verket kan betraktas som en utvecklingsroman. Även om romanen skildrar en tidsperiod på endast ett och ett halvt år så hinnerhuvudpersonen ändå undergå en betydande personlighetsförändring. Nietzsches Tragedinsfödelse med dess ovannämnda grundläggande begrepp lämpar sig ypperligt som referensram för en analys av denna förändring. Avhandlingen har också strukturerats utgående från de nietzscheanska begreppen sokratiskt, dionysiskt och apollinskt vilka alltså återspeglar huvudpersonens utvecklingsfaser. Från att ha varit en renodlad förnuftsmänniska väcks Sven Ingelet genom ett kortvarigt kärleksförhållande till det dionysiska med allt vad det innebär av känslorus och lidande. Att Ingelet nästan helt uppgått i sin roll som konstteoretiker har medfört att hans förhållningssätt till omvärlden utmärks av intresselös betraktelse. Till följd av sin viljesvaghet och bristande handlingskraft måstehan försöka behålla sin älskades gunst genom magiska pseudohandlingar. Detta leder in Ingelet i myternas värld. Hans verklighetsuppfattning får andra dimensioner än den vetenskapliga. Det dionysiska uppvaknandet medför tillsammans med det efterföljande brevskrivandet att Ingeletnår fram till en självkännedom och upphör att vara en främling i tillvaron. Ingelet utvecklar ocksåen ny konstsyn som förutsätter ett samband mellan konsten och livet. Detta apollinska utvecklingsstadium kännetecknas också av sanningsförmedlande drömmar, och av en tilltagande resignation som till slut utmynnar i ett självmord.

Tidigt fullständigt svenskt språkbad i Esbo

Avhandlingen behandlar tidigt fullständigt svenskt språkbad i Esbo. Arbetet utreder vad tidigt fullständigt språkbad innebär samt vad språkbadsföräldrars och språkbadslärares åsikter om språkbadet i Esbo är. Undersökningen omfattar 60 familjer samt samtliga lärare (14 st) som arbetar med språkbad i Esbo. Undersökningen består av två enkäter; en till språkbadsföräldrar och en tillspråkbadslärare. Av de 60 enkäter som sändes ut till språkbadsföräldrarna besvarades 45, dvs. 75%. 12 lärare av 14, dvs. 86%, besvarade den andra enkäten. Det är viktigt att känna till centrala begrepp i anslutning till tvåspråkighet, då man talar om andraspråkstillägnandet i språkbad. I detta arbete presenteras en modell (Sahi, 1999) som åskådliggör centrala begrepp i anslutning till tvåspråkighet. Tidigtfullständigt språkbad är ett program som är planerat att omfatta hela grundskolan. Språkbad är ämnat för enspråkiga majoritetsbarn i ett tvåspråkigt land. Dessa barn tillägnar sig minoritetsspråket i skolan. Språkbadet är inte enbart ett program, utan även en metod. Skillnaden mellan språkbad och traditionell undervisning i språk är att man i språkbadet betonar kommunikation framom grammatik. Målet medspråkbadet är funktionell tvåspråkighet. Många faktorer inverkar på andraspråkstillägnandet i språkbadet. I detta arbete betonas attitydernas och motivationens betydelse. Språkbad kräver en medveten och aktiv insats av föräldrarna. Vidare betonar litteraturen som behandlar språkbad undervisningsmetodernas betydelse samt språkbadslärarens viktiga roll. Föräldrarna är nöjda med språkbadsprogrammet, eftersom det givit goda resultat och motsvarat förväntningarna. Enligt föräldrarna är språkbad ett mjukt, modernt och effektivt program. Föräldrarna anser att barnen lär sig badspråket på ett naturligt sätt och även får en öppnare inställning till språk och kulturer. Föräldrarna betonar lärarnas viktiga insatser samt kontinuitetens betydelse. Vidare tycker föräldrarna att språkbadet borde inledas i ett tidigare skede och att eleverna borde ha mera kontakt med badspråket utanför skolan. Målet med att barnen går i språkbad är, enligt föräldrarna, att barnen ska förstå och tala språket flytande samtkänna kulturen som hör ihop med språket. Både föräldrarna och lärarna tycker att språkbadsklasserna är för stora och att det är brist på material. Lärarna anser att man mer än tidigare borde informera allmänheten, beslutsfattare samt föräldrar om verksamheten. Därtill tycker lärarna att samarbetet mellan daghem och skola samt specialundervisningen borde utvecklas. Lärarna betonar att språkbad inte lämpar sig för alla barn. Lärarna anser sig främst behöva praktiska råd av andra som arbetar med språkbad samt teoretisk kunskap. Både föräldrarna och lärarna tycker att språkbadsverksamheten i Esbo borde koordineras och att språkbadselevernas prestationer noggrant borde följas upp. Nyckelord: Tvåspråkighet, Språkbad, Andraspråkstillägnande Keywords: Bilingualism, Immersion, Second Language Aquisition.

Function and regulation of Cdk7

Understanding the process of cell division is crucial for modern cancer medicine due to the central role of uncontrolled cell division in this disease. Cancer involves unrestrained proliferation as a result of cells loosing normal control and being driven through the cell cycle, where they normally would be non-dividing or quiescent. Progression through the cell cycle is thought to be dependent on the sequential activation of cyclin-dependent kinases (Cdks). The full activation of Cdks requires the phosphorylation of a conserved residue (threonine-160 on human Cdk2) on the T-loop of the kinase domain. In metazoan species, a trimeric complex consisting of Cdk7, cyclin H and Mat1 has been suggested to be the T-loop kinase of several Cdks. In addition, Cdk7 have also been implicated in the regulation of transcription. Cdk7, cyclin H, and Mat1 can be found as subunits of general transcription factor TFIIH. Cdk7, in this context, phosphorylates the Carboxy-terminal domain (CTD) of the large subunit of RNA polymerase II (RNA pol II), specifically on serine-5 residues of the CTD repeat. The regulation of Cdk7 in these and other functions is not well known and the unambiguous characterization of the in vivo role of Cdk7 in both T-loop activation and CTD serine-5 phosphorylation has proved challenging. In this study, the fission yeast Cdk7-cyclin H homologous complex, Mcs6-Mcs2, is identified as the in vivo T-loop kinase of Cdk1(Cdc2). It also identifies multiple levels of regulation of Mcs6 kinase activity, i.e. association with Pmh1, a novel fission yeast protein that is the apparent homolog of metazoan Mat1, and T-loop phosphorylation of Mcs6, mediated by Csk1, a monomeric T-loop kinase with similarity to Cak1 of budding yeast. In addition, Skp1, a component of the SCF (Skp1-Cullin-F box protein) ubiquitin ligase is identified by its interactions with Mcs2 and Pmh1. The Skp1 association with Mcs2 and Pmh1 is however SCF independent and does not involve proteolytic degradation but may reflect a novel mechanism to modulate the activity or complex assembly of Mcs6. In addition to Cdk7, also Cdk8 has been shown to have CTD serine-5 kinase activity in vitro. Cdk8 is not essential in yeast but has been shown to function as a transcriptional regulator. The function of Cdk8 is unknown in flies and mammals. This prompted the investigation of murine Cdk8 and its potential role as a redundant CTD serine-5 kinase. We find that Cdk8 is required for development prior to implantation, at a time that is co-incident with a burst of Cdk8 expression during normal development. The results does not support a role of Cdk8 as a serine-5 CTD kinase in vivo but rather shows an unexpected requirement for Cdk8, early in mammalian development. The results presented in this thesis extends our current knowledge of the regulation of the cell cycle by characterizing the function of two distinct cell cycle regulating T-loop kinases, including the unambiguous identification of Mcs6, the fission yeast Cdk7 homolog, as the T-loop kinase of Cdk1. The results also indicate that the function of Mcs6 is conserved from fission yeast to human Cdk7 and suggests novel mechanisms by which the distinct functions of Cdk7 and Mcs6 could be regulated. These findings are important for our understanding of how progression of the cell cycle and proper transcription is controlled, during normal development and tissue homeostasis but also under condition where cells have escaped these control mechanisms e.g. cancer.

Molecular mechanisms of cancer predisposition in HNPCC/Lynch syndrome

Hereditary non-polyposis colorectal carcinoma (HNPCC; Lynch syndrome) is among the most common hereditary cancers in man and a model of cancers arising through deficient DNA mismatch repair (MMR). It is inherited in a dominant manner with predisposing germline mutations in the MMR genes, mainly MLH1, MSH2, MSH6 and PMS2. Both copies of the MMR gene need to be inactivated for cancer development. Since Lynch syndrome family members are born with one defective copy of one of the MMR genes in their germline, they only need to acquire a so called second hit to inactivate the MMR gene. Hence, they usually develop cancer at an early age. MMR gene inactivation leads to accumulation of mutations particularly in short repeat tracts, known as microsatellites, causing microsatellite instability (MSI). MSI is the hallmark of Lynch syndrome tumors, but is present in approximately 15% of sporadic tumors as well. There are several possible mechanisms of somatic inactivation (i.e. the second hit ) of MMR genes, for instance deletion of the wild-type copy, leading to loss of heterozygosity (LOH), methylation of promoter regions necessary for gene transcription, or mitotic recombination or gene conversion. In the Lynch syndrome tumors carrying germline mutations in the MMR gene, LOH was found to be the most frequent mechanism of somatic inactivation in the present study. We also studied MLH1/MSH2 deletion carriers and found that somatic mutations identical to the ones in the germline occurred frequently in colorectal cancers and were also present in extracolonic Lynch syndrome-associated tumors. Chromosome-specific marker analysis implied that gene conversion, rather than mitotic recombination or deletion of the respective gene locus accounted for wild-type inactivation. Lynch syndrome patients are predisposed to certain types of cancers, the most common ones being colorectal, endometrial and gastric cancer. Gastric cancer and uroepithelial tumors of bladder and ureter were observed to be true Lynch syndrome tumors with MMR deficiency as the driving force of tumorigenesis. Brain tumors and kidney carcinoma, on the other hand, were mostly MSS, implying the possibility of alternative routes of tumor development. These results present possible implications in clinical cancer surveillance. In about one-third of families suspected of Lynch syndrome, mutations in MMR genes are not found, and we therefore looked for alternative mechanisms of predisposition. According to our results, large genomic deletions, mainly in MSH2, and germline epimutations in MLH1, together explain a significant fraction of point mutation-negative families suspected of Lynch syndrome and are associated with characteristic clinical and family features. Our findings have important implications in the diagnosis and management of Lynch syndrome families.

Molecular pathogenesis of human parechovirus 1 infection

The Parechoviruses (HPEV) belong to the family Picornaviridae of positive-stranded RNA viruses. Although the parechovirus genome shares the general properties of other picornaviruses, the genus has several unique features when compared to other family members. We found that HPEV1 attaches to αv integrins on the cell surface and is internalized through the clathrin-mediated endocytic pathway. During he course of the infection, the Golgi was found to disintegrate and the ER membranes to swell and loose their ribosomes. The replication of HPEV1 was found to take place on small clusters of vesicles which contained the trans-Golgi marker GalT as well as the viral non-structural 2C protein. 2C was additionally found on stretches of modified ER-membranes, seemingly not involved in RNA replication. The viral non-structural 2A and 2C proteins were studied in further detail and were found to display several interesting features. The 2A protein was found to be a RNA-binding protein that preferably binds to positive sense 3 UTR RNA. It was found to bind also duplex RNA containing 3 UTR(+)-3 UTR(-), but not other dsRNA molecules studied. Mutagenesis revealed that the N-terminal basic-rich region as well as the C-terminus, are important for RNA-binding. The 2C protein on the other hand, was found to have both ATP-diphosphohydrolase and AMP kinase activities. Neither dATP nor other NTP:s were suitable substrates. Furthermore, we found that as a result of theses activities the protein is autophosphorylated. The intracellular changes brought about by the individual HPEV1 non-structural proteins were studied through the expression of fusion proteins. None of the proteins expressed were able to induce membrane changes similar to those seen during HPEV1 infection. However, the 2C protein, which could be found on the surface of lipid droplets but also on diverse intracellular membranes, was partly relocated to viral replication complexes in transfected, superinfected cells. Although Golgi to ER traffic was arrested in HPEV1-infected cells, none of the individually expressed non-structural proteins had any visible effect on the anterograde membrane traffic. Our results suggest that the HPEV1 replication strategy is different from that of many other picornaviruses. Furthermore, this study shows how relatively small differences in genome sequence result in very different intracellular pathology.

Campylobacter Infections of Domestic Origin in Finland

Campylobacter jejuni and C. coli are the leading causes of human bacterial gastroenteritis in developed countries. Most human Campylobacter infections are sporadic and a seasonal peak in the distribution of infections can be seen in the summer months in several countries, including Finland. A variety of risk factors for Campylobacter infections have been identified; handling and eating poultry, drinking unpasteurized milk, contact with domestic animals, and travelling abroad. However, the relative importance of the different risk factors in sporadic cases of Campylobacter infection remains unknown. In most cases, the infection is self-limiting and no specific treatment is required. Campylobacter enteritis can cause a wide range of complications, including reactive arthritis (ReA) that is reported in 1-5% of the cases. Seven clinical microbiology laboratories serving different geographical areas of Finland, participated in this multi-centre study, conducted during a seasonal peak in 2002. In a matched case-control study, domestically-acquired sporadic Campylobacter infections from three geographical areas were collected. The final study comprised 100 cases and 137 controls. Risk factors for sporadic domestically-acquired Campylobacter infections were identified on the basis of a questionnaire; swimming in natural waters was found to be a novel risk factor for Campylobacter infection. Other independent risk factors were tasting or eating raw or undercooked meat and drinking untreated water from a dug well. The role of bacterial strain and host characteristics are not fully understood in Campylobacter infections. Exposure factors, demographical characteristics, and the serotype of the Campylobacter isolate may affect the severity of the enteritis. This cross-sectional study comprised 114 patients with C. jejuni enteritis, diagnosed in three clinical microbiology laboratories; most of the patients had participated in the previous case-control study. Swimming was associated with age ≤ 5 years and serotype Pen 6,7 was found significantly more often among patients reporting swimming. The geographical distribution among serotypes varied; serotype Pen 4-complex appeared more often in patients from urban areas and serotype Pen 21 among patients from more rural areas. Thus, risk factors and sources of infection for C. jejuni infection may vary among individuals depending on age and geographical location. The in vitro susceptibilities of C. jejuni and C. coli strains isolated from patients infected abroad (85 strains) or domestically (393 strains) revealed that susceptibility to erythromycin is still high, even among isolates of foreign origin. However, the novel antimicrobial agent telithromycin did not offer any advantage over erythromycin; isolates with high minimal inhibitory concentrations (MICs) for erythromycin also showed reduced susceptibility to telithromycin. Reduced susceptibility to fluoroquinolones was detected almost exclusively among isolates of foreign origin and half of these isolates with high MICs for fluoroquinolones also showed elevated MICs for doxycycline. Questionnaires concerning complications associated with C. jejuni enteritis were sent to patients two months after becoming ill; 201 patients from seven different geographical areas were included in the study. Musculoskeletal complications after C. jejuni infection were commonly reported by patients (39%). The incidence of classical ReA was 4% and that of Achilles enthesopathy and/or heel pain 9%. Other C. jejuni-associated reactive joint symptoms were commonly reported, however, due to their milder nature seldom seen and diagnosed by a physician. The severity of the enteritis may predict further complications; stomach ache during enteritis was connected to the development of later joint pain. Early antimicrobial treatment, within two days from the start of symptoms, shortened the duration of diarrhoea by two days but did not prevent later musculoskeletal complications. Campylobacter is an important human enteropathogen and causes a significant burden of illness. As the incidence of Campylobacter infections is high, the importance of the infection and the occurrence of complications will increase. This stresses the importance of understanding the risk factors for acquiring Campylobacter infection and how bacterial strain and host characteristics may affect the risk for infection. The role of antimicrobial treatment for acute Campylobacter enteritis seems to be marginal and should be used restrictively.

Skogsbränslets elementära sammansättning med tanke på förbränningsprocessen och för näringsämnesförluster i ekosystemet

There are several reasons for increasing the usage of forest biomass for energy in Finland. Apart from the fact that forest biomass is a CO2 -neutral energy source, it is also a domestic resource distributed throughout the country. Usage of forest biomass in the form of logging residues decreases Finland’s dependence of energy import and increases both incomes and employment. Wood chips are mainly made from logging residues, which constitute 64 % of the raw material. A large-scale use of forest biomass requires heed also to the potential negative aspects. Forest bioenergy is used extensively, but its impacts on the forests soil nutrition and carbon balance has not been studied much. Nor have there been many studies on the heavy metal or chlorine content of logging residues. The goal of this study was to examine the content of carbon, macronutrients, heavy metals and other for the combustion harmful substances in Scots pine and Norway spruce wood chips, and to estimate the effect of harvesting of logging residues on the forests carbon and nutrient balance. Another goal was to examine the energy content of the clear cut remains. The Wood chips for this study were gathered from pine and spruce dominated clear cut sites in southern Finland, in the costal forests between Hankoo and Siuntio. The number of sample locations were 29, and the average area was 3,15 ha and the average timber volume 212,6 m3 ha -1. The average logged timber volume was for Scots pine timber 70 m3 ha -1 and for Norway spruce timber 124 m3 ha -1 and for deciduous timber (birch and alder) 18,5 m3 ha -1. The proportion of spruce in the logging residues and the stand-volume were relevant for how much nutrients were taken from the forest ecosystem when harvesting logging residues. In this study it was noted that the nutrient content of the logging residues clearly increased when the percentage of spruce in the timber volume increased. The S, K, Na and Cl -contents in the logging residues in this study increased with an increasing percentage of spruce, which is probably due to the fact that the spruce is an effective collector of atmospheric dry-deposition. The amounts of nutrients that were lost when harvesting logging residues were less than those referred to in the literature. Within a circulation period (100 years), the forest soil gets substantially more nutrients from atmospheric deposition, litter fall and weathering than is lost through harvesting of logging residues after a clear cut. Harvesting of the logging residues makes for a relatively modest increase of the quantity of carbon that is removed from the forest compared to traditional forestry. Due to the fact that the clear cut remains in my study showed a high content of chlorine, there is a risk of corrosion in connection to the incineration of the logging residues in power plants especially at coastal areas/forests. The risk of sulphur -related corrosion is probably rather small, because S concentrations are relatively low in woodchips. The clear cut remains showed rather high heavy metal contents. If the heavy metal contents in this study are representative for the clear cut remains in the coastal forests generally, there might be reason to exert some caution when using the ash for forest fertilizing purposes.

Agronomic challenges for organic crop husbandry

With respect to resource management and environmental impact, organic farming offers rationales for agricultural sustainability. However, agronomic productivity is usually higher with conventional farming. This work aimed at investigating two factors of major importance for the agronomic productivity of organic crop husbandry, nitrogen (N) supply through symbiotic N fixation (SNF) and weed occurrence. Perennial red clover-grass leys and spring cereal crops subjected to regular agricultural practices were studied on 34 organic farms located in the southern and the north-western coastal regions of Finland. Herbage growth, clover content as a proportion of the ley and extent of SNF in perennial leys, and the occurrence of weed species and weed-crop competition in spring cereal stands were related to climate conditions, soil properties, and management measures. The herbage accumulated from the first and the second cut of one- and two-year-old leys averaged 7.5 t DM ha-1 (SD ± 1.7 t DM ha-1); the clover content averaged 43.9% (SD ± 18.8%). Along with the clover content, herbage production decreased with ley age. Radiation use efficiency (RUE) correlated positively with clover proportion but despite low clover contents, three-year-old leys were still productive with regard to RUE. SNF in the accumulated annual growth of one- and two-year-old leys averaged 247.5 kg N ha-1 yr-1 (SD ± 114.4 kg N ha-1 yr-1). It was supposed that if red clover-grass leys constituted 40% of the rotation, then the mean N supply by SNF would be able to sustain two or three succeeding cereal crops (green manure and forage ley, respectively), yielding 3.0 to 4.0 t grain ha-1. Being a function of clover biomass, the SNF increased from the first to the second cut and thereafter declined with ley age. Coefficients of variation of clover contents (and SNF) between and within fields were around 50%, which was about twice as high as those of herbage production. The lower were the clover contents, the higher were the within-field variations of clover as a proportion of the ley. Low clover contents in one-year-old leys and increasing variability with ley age suggested that red clover growth was limited by poor establishment and poor overwintering. The proportions of clover in leys were lower and their variability was higher in the northwest than in the south. Soil properties, primarily texture and structure, had a major impact on clover proportion and herbage production, which largely explained regional differences in ley growth. Within-field variability of soil properties can be amended through site-specific measures, including drainage, liming, and applications of organic manures and mineral fertilizers. Overwintering and the persistence of leys can be improved by the choice of winter-hardy varieties, careful establishment and the appropriate harvest regime. Mean grain yields of spring cereal crops amounted to 3.2 t ha-1 in the south and 3.6 t ha-1 in the northwest. At 570 and 565 m-2 for the south and northwest respectively, mean weed densities did not differ between the regions, whereas the respective mean weed biomass of 697 and 1594 kg dry weight ha-1, respectively did differ. Weed abundance varied remarkably between single fields. The number of weed species was higher in the south than in the northwest. For example, Fumaria officinalis and Lamium spp. were found only in the south. Frequencies and abundances of Lapsana communis, Myosotis arvensis, Polygonum aviculare, Tripleurospermum inodorum, and Vicia spp. were higher in the south, whereas those of Elymus repens, Persicaria spp. and Spergula arvensis were higher in the northwest. The number of years since conversion to organic farming, i.e. long-term management, was one of the variables that explained the abundance of single weed species. E. repens was the weed species whose biomass increased most with the duration of organic farming. Another significant variable was crop biomass, which was affected by short-term management. The presence of different weed species was related to the duration of organic farming and to low crop yield. This finding demonstrated that it was not the organic farming regime per se, which resulted in high weed infestation and low yielding crops, but failures in the understanding and the management of organic farming systems. Successful weed control relies on farm- and field-specific long- and short-term management approaches. The agronomic productivity of ley and spring cereal crops managed by full-time farmers with an interest in organic farming was on the same level as of the mean for conventional farming. Given the many options for further improvements of the agronomic performance of organic arable systems, organic farming offers foundations for the development of sustainable agriculture. The main threat to the sustainability of farming in Finland, both conventional and organic, is the spatial separation of crop production and animal husbandry by region, along with the simplification of associated crop rotations.
