Yksilön hyvä, yhteinen hyvä? Näytteenluovuttajan oikeudet biopankkitutkimuksessa.

Tieteen ja teknologian kehittyminen sekä lisääntynyt ymmärrys sairauksien syntyyn vaikuttavista tekijöistä on avannut uudenlaisia mahdollisuuksia hyödyntää ihmisperäisiä näytteitä. Vuoden 2013 syyskuussa voimaan astuneen biopankkilain tarkoituksena on kirkastaa ihmisperäisten näytteiden tutkimuskäyttöä koskevaa sääntelyä ja tehostaa näytteiden tutkimuskäyttöä, mikä osaltaan mahdollistaa yksilöllisempien ja kohdennetumpien vaihtoehtojen kehittämisen sairauksien diagnostiikkaan, hoitoon ja hoidon vaikuttavuuden seuraamiseen. Biopankkitutkimusta tehdään vapaaehtoisilta luovuttajilta saaduilla ihmisperäisillä näytteillä sekä niihin liitettävillä tiedoilla, jotka on kerätty biopankkiin odottamaan sopivan tutkimuskysymyksen nousemista. Biopankkilain voimantulon myötä on mahdollista säilöä näytteitä keräyshetkellä vielä määrittelemättömään tutkimukseen. Koska biopankkitutkimuksessa hyödynnetään jo aikaisemmin kerättyjä näytteitä, tutkimuksessa ei tarvitse puuttua yksilön ruumiilliseen koskemattomuuteen. Vaikka tätä yksilön fyysiseen koskemattomuuteen liittyvää suojeluintressiä ei enää ole, biopankkitutkimuksessa yksilöön liittyvä suojelun tarve kytkeytyy hänen yksityisyyden suojaansa ja itsemääräämisoikeuden turvaamiseen. Yhteistä hyvää ja koko väestön terveyttä edistettäessä on ensiarvoisen tärkeää huolehtia näytteenluovuttajan oikeuksien turvaamisesta, mikä osaltaan mahdollistaa biopankkitutkimusta kohtaan tunnettavan luottamuksen rakentumisen ja näytteenluovuttajien sitoutumisen biopankkitutkimukseen. Näytteenluovuttajan oikeuksien tukeminen kytkeytyy biopankkitutkimuksessa erityisiin avoimiin ja selkeisiin suostumuskäytänteisiin, näytteenluovuttajien riittävään informointiin, yksityisyyden suojaamiseen sekä biopankkitutkimuksessa yleisesti noudatettaviin eettisiin toimintaperiaatteisiin ja ihmisarvon kunnioittamiseen. Useisiin perusoikeuksiin kiinnittyvän itsemääräämisoikeuden turvaamisessa näytteenluovuttajalta saadulla vapaaehtoisella suostumuksella on merkittävä rooli. Institutionaalista tukea näytteenluovuttajan suojan tarve saa erityisesti uudenlaista ihmisoikeustraditiota edustavasta biolääketiedesopimuksesta, jonka taustalla vaikuttaa ajatus ihmisen suojelemisesta psykofyysisenä kokonaisuutena. Tärkeimpiä oikeuslähteitä tutkielmassani ovat biopankkilain ja sen esitöiden ohella biolääketiedesopimus siihen liittyvine lisäpöytäkirjoineen. Suurta tukea olen saanut myös useista Lasse Lehtosen teoksista, Salla Lötjösen väitöskirjasta ”Lääketieteellinen tutkimus ihmisillä”, Irma Pahlmanin väitöskirjasta ”Potilaan itsemääräämisoikeus” ja Liisa Niemisen artikkelista ”Ihmisarvon loukkaamattomuus perus- ja ihmisoikeussuojan lähtökohtana” sekä useista lääketieteellisissä aikakausjulkaisuissa ilmestyneistä artikkeleista.

”Mä en oo kässää”. Yleinen kouluviihtyvyys ja käsityöviihtyvyys peruskoulun neljännen, kuudennen ja kahdeksannen luokan oppilailla

Tutkimuksen tavoitteena oli selvittää miten neljännen, kuudennen ja kahdeksannen luokan oppilaat viihtyvät yleisesti koulussa, eri oppitunneilla ja erityisesti käsityön oppiaineessa. Tarkoituksena oli myös selvittää käsityön oppitunnilla viihtymisen yhteyttä yleiseen kouluviihtyvyyteen. Vertailimme eri luokka-asteen eroja sekä eroa tyttöjen ja poikien välillä. Tutkimuksen aineisto kerättiin yhdestä satakuntalaisesta yhtenäiskoulusta syyslukukaudella 2015. Tutkimukseen osallistui 110 oppilasta, 53 poikaa ja 57 tyttöä. Tutkimustulosten analysoinnissa käytettiin tilastollisia ja laadullisia menetelmiä. Tilastolliseen analyysiin käytettiin SPSS- ja Professional statistics -tilasto-ohjelmia. Tiedonkeruumenetelmänä käytettiin oppilaskyselyä, joka toteutettiin verkkoympäristössä tehtävällä Webropol-lomakkeella. Oppilaskysely toteutettiin oppilaiden koulupäivän aikana heidän käytössään olevilla tablettitietokoneilla. Tämän tutkimuksen tulosten mukaan alakoululaiset viihtyivät koulussa paremmin kuin yläkoululaiset. Aiemmista tutkimuksista poiketen yläkoulun tytöt viihtyivät koulussa poikia huonommin. Alakoulussa erot tyttöjen ja poikien välillä olivat pienemmät. Tulosten mukaan tutkitut oppilaat viihtyivät valtakunnallisesti ja maakunnallisesti keskivertoa paremmin koulussa. Käsityön oppiaineessa viihtymisen kokeminen ei ollut tulosten mukaan suoraan yhteydessä oppilaiden kokemaan yleiseen kouluviihtyvyyteen. Huolimatta oppilaan yleisen kouluviihtyvyyden alhaisuudesta, saattoi käsityön oppiaineen tuoma mielekkyys olla korkea. Taito- ja taideaineissa koettu mielekkyys oli korkeampaa verrattuna reaaliaineisiin sekä käsityön oppiaineeseen. Oppilaiden erot kouluviihtyvyydessä selittyvät luokka-asteen muuttuessa korkeammaksi. Haasteena opettajille ja opetussuunnitelman laatijoille on kehittää opetusta siten, että oppilaiden kokema kouluviihtyvyys saataisiin pidettyä korkealla tasolla läpi koko peruskoulun. Kouluviihtyvyys on tärkeä tekijä oppilaiden kouluvalintojen, tulevan koulutuspolkujen ja ammattiuran kannalta.

”Et mul on virkaa täs maailmas” – Yli Hyvä Juttu luo toivoa syrjäytyneille nuorille

Tämän laadullisen tutkimuksen tarkoituksena oli selvittää, onko viranomaisten ja palokuntanuorisotyötä tekevien näkökulmasta sopimuspalokunnan nuorisotoiminnalla myönteisiä vaikutuksia syrjäytymisuhan alla oleviin lapsiin ja nuoriin. Samalla tutkittiin, millaisia käsityksiä viranomaistoimijoilla ja avainhenkilöillä on harrastustoiminnasta elämänhallinnan edistäjänä. Tutkimusta taustoittaa ajatus osallisuuden tuottamasta hyvinvoinnista sekä teoria Toivosta. Tutkimuksen teoreettinen viitekehys perustuu C.R. Snyderin Theory of Hope –ajattelumallille. Tutkimusaineisto kerättiin kyselylomakkeella, strukturoiduilla haastatteluilla, avaininformanttihaastatteluilla sekä ryhmähaastatteluilla. Tutkimukseen osallistuneet ovat suomalaisia sopimuspalokuntien nuoriso-osastojen vastuuhenkilöitä tai sosiaali- ja pelastusviranomaisia. Aineisto analysoitiin laadullisin menetelmin aineistolähtöistä sisällönanalyysiä käyttäen. Tutkimus on Terveyden ja Hyvinvoinnin laitoksen (THL) Yli Hyvä Juttu -hankkeen (YHJ) arviointitutkimuksen osatutkimus. Se liittyy lasten ja nuorten syrjäytymisen ehkäisyyn kehitetyn sosiaalisen vahvistamisen toimintamallin juurruttamiseen ja kehittämiseen. Toimintamallissa sosiaaliviranomaiset ja muut syrjäytymisuhan alla olevien nuorien kanssa toimivat ohjaavat aktiivisesti heitä sopimuspalokuntien palokuntanuorisotoimintaan. Tulokset viittaavat siihen, että palokuntanuorisotyön ja toimintamallin voi katsoa tukevan nuoren minäpystyvyyden kehittymistä, optimistista ajattelua itsestään ja tulevaisuudestaan. Se ohjaa valitsemaan terveitä päämääriä tulevaisuuteen ja tukee niissä sekä antaa nuorelle erilaisia vahvistavia kokemuksia toimijuudesta. Aineiston perusteella voidaan myös todeta, että sosiaalinen vahvistaminen on merkityksellinen asia palokuntanuorisotyössä ja YHJ -toimintamallissa, joka ohjaa nuoria harrastuksen pariin. Yhteiskunnallisesta näkökulmasta palokuntaharrastus tukee nuoren yhdenvertaisuutta ja toiminnassa mukana ollessa opitaan kansalaistaitoja. Sosiaalisesta näkökulmasta katsoessa tulokset osoittavat, että yhteistoimintaan osalliseksi pääseminen tukee nuoren päämäärätietoisuutta. Emootioiden tasolla voidaan katsoa turvallisuuden tunteen lisääntyvän palokuntatoiminnan autoritäärisen toimintakulttuurin vuoksi.

Purification of pharmaceuticals and nutraceutical compounds by sub- and supercritical extraction and chromatography

This thesis discusses the use of sub- and supercritical fluids as the medium in extraction and chromatography. Super- and subcritical extraction was used to separate essential oils from herbal plant Angelica archangelica. The effect of extraction parameters was studied and sensory analyses of the extracts were done by an expert panel. The results of the sensory analyses were compared to the analytically determined contents of the extracts. Sub- and supercritical fluid chromatography (SFC) was used to separate and purify high-value pharmaceuticals. Chiral SFC was used to separate the enantiomers of racemic mixtures of pharmaceutical compounds. Very low (cryogenic) temperatures were applied to substantially enhance the separation efficiency of chiral SFC. The thermodynamic aspects affecting the resolving ability of chiral stationary phases are briefly reviewed. The process production rate which is a key factor in industrial chromatography was optimized by empirical multivariate methods. General linear model was used to optimize the separation of omega-3 fatty acid ethyl esters from esterized fish oil by using reversed-phase SFC. Chiral separation of racemic mixtures of guaifenesin and ferulic acid dimer ethyl ester was optimized by using response surface method with three variables per time. It was found that by optimizing four variables (temperature, load, flowate and modifier content) the production rate of the chiral resolution of racemic guaifenesin by cryogenic SFC could be increased severalfold compared to published results of similar application. A novel pressure-compensated design of industrial high pressure chromatographic column was introduced, using the technology developed in building the deep-sea submersibles (Mir 1 and 2). A demonstration SFC plant was built and the immunosuppressant drug cyclosporine A was purified to meet the requirements of US Pharmacopoeia. A smaller semi-pilot size column with similar design was used for cryogenic chiral separation of aromatase inhibitor Finrozole for use in its development phase 2.

Characterisation and processing of amorphous binary mixtures with low glass transition temperature

The number of drug substances in formulation development in the pharmaceutical industry is increasing. Some of these are amorphous drugs and have glass transition below ambient temperature, and thus they are usually difficult to formulate and handle. One reason for this is the reduced viscosity, related to the stickiness of the drug, that makes them complicated to handle in unit operations. Thus, the aim in this thesis was to develop a new processing method for a sticky amorphous model material. Furthermore, model materials were characterised before and after formulation, using several characterisation methods, to understand more precisely the prerequisites for physical stability of amorphous state against crystallisation. The model materials used were monoclinic paracetamol and citric acid anhydrate. Amorphous materials were prepared by melt quenching or by ethanol evaporation methods. The melt blends were found to have slightly higher viscosity than the ethanol evaporated materials. However, melt produced materials crystallised more easily upon consecutive shearing than ethanol evaporated materials. The only material that did not crystallise during shearing was a 50/50 (w/w, %) blend regardless of the preparation method and it was physically stable at least two years in dry conditions. Shearing at varying temperatures was established to measure the physical stability of amorphous materials in processing and storage conditions. The actual physical stability of the blends was better than the pure amorphous materials at ambient temperature. Molecular mobility was not related to the physical stability of the amorphous blends, observed as crystallisation. Molecular mobility of the 50/50 blend derived from a spectral linewidth as a function of temperature using solid state NMR correlated better with the molecular mobility derived from a rheometer than that of differential scanning calorimetry data. Based on the results obtained, the effect of molecular interactions, thermodynamic driving force and miscibility of the blends are discussed as the key factors to stabilise the blends. The stickiness was found to be affected glass transition and viscosity. Ultrasound extrusion and cutting were successfully tested to increase the processability of sticky material. Furthermore, it was found to be possible to process the physically stable 50/50 blend in a supercooled liquid state instead of a glassy state. The method was not found to accelerate the crystallisation. This may open up new possibilities to process amorphous materials that are otherwise impossible to manufacture into solid dosage forms.

Neuro- and immunotoxic effects of fumonisin B1 in cells

Fumonisin B1 (FB1) is a mycotoxin produced by the fungus Fusarium verticillioides, which commonly infects corn and other agricultural products. Fusarium species can also be found in moisture-damaged buildings, and therefore there may also be human exposure to Fusarium mycotoxins, including FB1. FB1 affects the metabolism of sphingolipids by inhibiting the enzyme ceramide synthase. It is neuro-, hepato- and nephrotoxic, and it is classified as possibly carcinogenic to humans. This study aimed to clarify the mechanisms behind FB1-induced neuro- and immunotoxicity. Four neural and glial cell lines of human, rat and mouse origin were exposed to graded doses of FB1 and the effects on the production of reactive oxygen species, lipid peroxidation, intracellular glutathione levels, cell viability and apoptosis were investigated. Furthermore, the effects of FB1, alone or together with lipopolysaccharide (LPS), on the mRNA and protein expression levels of different cytokines and chemokines were studied in human dendritic cells (DC). FB1 induced oxidative stress and cell death in all cell lines studied. Generally, the effects were only seen after prolonged exposure at 10 and 100 µM of FB1. Signs of apoptosis were also seen in all four cell lines. The sensitivities of the cell lines used in this study towards FB1 may be classified as human U-118MG glioblastoma > mouse GT1-7 hypothalamic > rat C6 glioblastoma > human SH-SY5Y neuroblastoma cells. When comparing cell lines of human origin, it can be concluded that glial cells seem to be more sensitive towards FB1 toxicity than those of neural origin. After exposure to FB1, significantly increased levels of the cytokine interferon-γ (IFNγ) were detected in human DC. This observation was further confirmed by FB1-induced levels of the chemokine CXCL9, which is known to be regulated by IFNγ. During co-exposure of DC to both LPS and FB1, significant inhibitions of the LPS-induced levels of the pro-inflammatory cytokines interleukin-6 (IL-6) and IL-1β, and their regulatory chemokines CCL3 and CCL5 were observed. FB1 can thus affect immune responses in DC, and therefore, it is rather likely that it also affects other types of cells participating in the immune defence system. When evaluating the toxicity potential of FB1, it is important to consider the effects on different cell types and cell-cell interactions. The results of this study represent new information, especially about the mechanisms behind FB1-induced oxidative stress, apoptosis and immunotoxicity, as well as the varying sensitivities of different cell types towards FB1.

Towards real-time understanding of processes in pharmaceutical powder technology

There is a need for better understanding of the processes and new ideas to develop traditional pharmaceutical powder manufacturing procedures. Process analytical technology (PAT) has been developed to improve understanding of the processes and establish methods to monitor and control processes. The interest is in maintaining and even improving the whole manufacturing process and the final products at real-time. Process understanding can be a foundation for innovation and continuous improvement in pharmaceutical development and manufacturing. New methods are craved for to increase the quality and safety of the final products faster and more efficiently than ever before. The real-time process monitoring demands tools, which enable fast and noninvasive measurements with sufficient accuracy. Traditional quality control methods have been laborious and time consuming and they are performed off line i.e. the analysis has been removed from process area. Vibrational spectroscopic methods are responding this challenge and their utilisation have increased a lot during the past few years. In addition, other methods such as colour analysis can be utilised in noninvasive real-time process monitoring. In this study three pharmaceutical processes were investigated: drying, mixing and tabletting. In addition tablet properties were evaluated. Real-time monitoring was performed with NIR and Raman spectroscopies, colour analysis, particle size analysis and compression data during tabletting was evaluated using mathematical modelling. These methods were suitable for real-time monitoring of pharmaceutical unit operations and increase the knowledge of the critical parameters in the processes and the phenomena occurring during operations. They can improve our process understanding and therefore, finally, enhance the quality of final products.

Governance Matters : China's Developing Western Region with a Focus on Qinghai Province

This study is about governance in contemporary China. The focus is on Qinghai Province, one of the twelve provincial-level units included in the western region development strategy launched in 2000 by the government of China. Qinghai, the subject of the case study, is not a very well-known province. Hence, this study is significant, because it provides new knowledge about the province of Qinghai, its governance and diverse challenges, and deepens one s overall knowledge regarding China. Qinghai province is one of the slowest developing regions of China. My research problem is to analyze to what extent provincial development correlates with the quality of governance. The central concept of this research is good governance. This dissertation employs a grounded theory approach while the theoretical framework of this study is built on the Three World s approach of analyzing the three main themes, namely, the environment, economic development, and cultural diversity, and to support the empirical work. Philosophical issues in the humanities and contemporary theories of governance are brought in to provide deeper understanding of governance, and to understand to what extent and how characteristics of good governance (derived from the Western canon) are combined with Chinese tradition. A qualitative research method is chosen to provide a deeper understanding of the contemporary challenges of Qinghai (and China) and to provide some insight into the role and impact of governance on provincial development. It also focuses on the Tibetan ethnic group in order to develop as full an understanding as possible about the province. The challenges faced by Qinghai concern in particular its environment, economic development, and cultural diversity, all of which are closely interrelated. The findings demonstrate that Qinghai Province is not a powerful actor, because it has weak communications with the central government and weak collaboration with its stakeholders and civil society. How Qinghai s provincial government conducts provincial development remains a key question in terms of shaping the province s future. The question is how is Qinghai s government best able to govern in a way that is beneficial for the people. This study demonstrates that this is a significant question that challenges governance everywhere, and particularly in China given the absence of democracy. This study provides the ingredients for reflection as to how provincial government can be motivated to choose to govern in a sustainable way, instead of leaning on growth factors with too little consideration about the impact on the environment and the people.

Mapinduzi Daima – Revolution Forever : Using the 1964 Revolution in Nationalistic Political Discourses in Zanzibar

This Master's thesis examines two opposite nationalistic discourses on the revolution of Zanzibar. Chama cha Mapinduzi (CCM), the party in power since the 1964 revolution defends its revolutionary and "African" heritage in the current multi-party system. New nationalists, including among others the main opposition party Civic United Front (CUF), question both the 1964 revolution and the post-revolution period and blame CCM for empty promises, corruption and ethnic discrimination. This study analyzes the role of a significant historical event in the creation of nationalistic ideology and national identity. The 1964 revolution forms the nucleus of various debates related to the history of Zanzibar: slavery, colonialism, racial discrimination and political violence. Representations of these Social constructivist principles form the basis of this study, and central concepts in the theoretical framework are nationalism, national identity, ethnicity and race. I use critical discourse analysis as my research method, lean on the work by Teun A. van Dijk and Norman Fairclough as the most significant researchers in this field. I examine particularly the ways in which linguistic methods, such as stereotypes and metaphors are used to form in- and out-groups ("us" vs. "others"). My material, both in Swahili and English, was collected mainly in Tanzania in the fall of 2007 and from online sources in the spring of 2009. It includes publications by the Zanzibari government between the years of 1964-2000 (12), official speeches for the Revolution Day or the Union Day (12), articles from Tanzanian newspapers from the 1990s until the year of 2009 (15), memoirs and political pamphlets (10), blog posts and opinion pieces from four different websites (8), and interviews or personal communication in Zanzibar, Dar es Salaam and Uppsala (8). Nationalistic rhetoric often creates enemy images by using binary good-bad oppositions. Both discourses in this study build identities on the basis of "otherness" and exclusion, with the intent of emphasizing the particularity of the own group and excluding "evilness" outside the own reference group. These opposite views on the 1964 revolution as the main axis of the history of Zanzibar build different portraits of the nation and Zanzibari-ness (Uzanzibari). CCM still relies on the pre-revolutionary enemy images of Arabs as selfish rulers and cruel slave traders. For CCM, Zanzibar is primarily an "African" nation and a part of Tanzania which is threatened by "Arabs", the outsiders. In contrast, the new nationalists stress the long history of Zanzibar as multi-racial, cosmopolitan and formerly independent country which has its own, separate culture and identity from mainland Tanzanians. Heshima, honour/respect, one of the basic values of Swahili culture, occupies a central role in both discourses: the main party emphasizes that the revolution returned "heshima" to the Zanzibari Africans after centuries of humiliation, whereas the new nationalists claim that ever since the revolution all "non-Africans" have been humiliated and lost their "heshima". According to the new nationalists, true Zanzibari values which include tolerance and harmony between different "races" were lost when the "foreign" revolutionaries arrived from the mainland. Consequently, they see the 1964 revolution as Tanganyikan colonialism which began with the help of Western countries, and maintain that this "colonialism" still continues in the violent multi-party elections.

Structure informationnelle et constructions du kabyle : Etude de trois types de phrase dans le cadre de la grammaire constructionnelle

Information structure and Kabyle constructions Three sentence types in the Construction Grammar framework The study examines three Kabyle sentence types and their variants. These sentence types have been chosen because they code the same state of affairs but have different syntactic structures. The sentence types are Dislocated sentence, Cleft sentence, and Canonical sentence. I argue first that a proper description of these sentence types should include information structure and, second, that a description which takes into account information structure is possible in the Construction Grammar framework. The study thus constitutes a testing ground for Construction Grammar for its applicability to a less known language. It constitutes a testing ground notably because the differentiation between the three types of sentences cannot be done without information structure categories and, consequently, these categories must be integrated also in the grammatical description. The information structure analysis is based on the model outlined by Knud Lambrecht. In that model, information structure is considered as a component of sentence grammar that assures the pragmatically correct sentence forms. The work starts by an examination of the three sentence types and the analyses that have been done in André Martinet s functional grammar framework. This introduces the sentence types chosen as the object of study and discusses the difficulties related to their analysis. After a presentation of the state of the art, including earlier and more recent models, the principles and notions of Construction Grammar and of Lambrecht s model are introduced and explicated. The information structure analysis is presented in three chapters, each treating one of the three sentence types. The analyses are based on spoken language data and elicitation. Prosody is included in the study when a syntactic structure seems to code two different focus structures. In such cases, it is pertinent to investigate whether these are coded by prosody. The final chapter presents the constructions that have been established and the problems encountered in analysing them. It also discusses the impact of the study on the theories used and on the theory of syntax in general.

Spontaanin puheen prosodinen jaksottelu

The common focus of the studies brought together in this work is the prosodic segmentation of spontaneous speech. The theoretically most central aspect is the introduction and further development of the IJ-model of intonational chunking. The study consists of a general introduction and five detailed studies that approach prosodic chunking from different perspectives. The data consist of recordings of face-to-face interaction in several spoken varieties of Finnish and Finland Swedish; the methodology is usage-based and qualitative. The term “speech prosody” refers primarily to the melodic and rhythmic characteristics of speech. Both speaking and understanding speech require the ability to segment the flow of speech into suitably sized prosodic chunks. In order to be usage-based, a study of spontaneous speech consequently needs to be based on material that is segmented into prosodic chunks of various sizes. The segmentation is seen to form a hierarchy of chunking. The prosodic models that have so far been developed and employed in Finland have been based on sentences read aloud, which has made it difficult to apply these models in the analysis of spontaneous speech. The prosodic segmentation of spontaneous speech has not previously been studied in detail in Finland. This research focuses mainly on the following three questions: (1) What are the factors that need to be considered when developing a model of prosodic segmentation of speech, so that the model can be employed regardless of the language or dialect under analysis? (2) What are the characteristics of a prosodic chunk, and what are the similarities in the ways chunks of different languages and varieties manifest themselves that will make it possible to analyze different data according to the same criteria? (3) How does the IJ-model of intonational chunking introduced as a solution to question (1) function in practice in the study of different varieties of Finnish and Finland Swedish? The boundaries of the prosodic chunks were manually marked in the material according to context-specific acoustic and auditory criteria. On the basis of the data analyzed, the IJ-model was further elaborated and implemented, thus allowing comparisons between different language varieties. On the basis of the empirical comparisons, a prosodic typology is presented for the dialects of Swedish in Finland. The general contention is that the principles of the IJ-model can readily be used as a methodological tool for prosodic analysis irrespective of language varieties.

Coordinated Verb Pairs in Texts

This dissertation discusses the relation between lexis, grammar and textual organisation. The major premise adopted here is that grammatical structures are motivated both by semantic potential of words and by text-pragmatic demands. In other words, it is argued that grammatical structures form the interface between lexis and textual organisation, and that linguistic analysis should not concentrate on analysing grammatical structures in isolation, independent of context. From this point of view, grammatical structures are said to be 'well-formed' only in relation to the context they occur in. This study is based on a corpus of three million words of recent Finnish fiction from which all the occurrences of the coordinated verb pairs ([V ja V] -pairs]) containing one of the intransitive motion verbs 'lähteä' (to go), 'mennä' (to go), 'päästä' (to get into), 'nousta' (to get up), and 'laskea' (to go down), were extracted. This set of verbs was established using methods described in earlier work by Lagus & Airola (2001, and 2005). The quantitative analysis of the [V ja V] -pairs was used to carry out a qualitative analysis of individual texts. In analysing the texts, an analogy was made between musical and textual structure. The results show among others that individual verbs specialise in different functions when occurring in coordinated verb pairs. One aspect was that those verb pairs including the verb 'nousta' tend to function as markers of textual boundaries and thus reflect the organisation of narrative substance. The verb 'mennä' has weakened literal meanings, but strengthened modal meanings when occurring in [V ja V] -pairs, and, in many cases, the verb 'lähteä' in [V ja V] -pairs function as an aspectual marker rather than a pure verb of motion. That there is a gradient from the concrete sense of motion into more differentiated senses of a verb in [V ja V] -pairs alongside the structure-creating potential of the [V ja V] -pairs themselves suggest an ongoing grammaticalisation process of the patterns discussed.

Speech Rhythm in an Interlanguage Perspective : Finnish Adolescents Speaking English

Speech rhythm is an essential part of speech processing. It is the outcome of the workings of a combination of linguistic and non-linguistic parameters, many of which also have other functions in speech. This study focusses on the acoustic and auditive realization of two linguistic parameters of rhythm: (1) sentence stress, and (2) speech rate and pausing. The aim was to find out how well Finnish comprehensive school pupils realize these two parameters in English and how native speakers of English react to Finnish pupils English rhythm. The material was elicited by means of a story-telling task and questionnaires. Three female and three male pupils representing different levels of oral skills in English were selected as the experimental group. The control group consisted of two female and two male native speakers of English. The stories were analysed acoustically and auditorily with respect to interstress intervals, weak forms, fundamental frequency, pausing, and speech as well as articulation rate. In addition, 52 native speakers of English were asked to rate the intelligibility of the Finnish pupils English with respect to speech rhythm and give their attitudes on what the pupils sounded like. Results showed that Finnish pupils can produce isochronous interstress intervals in English, but that too large a proportion of these intervals contain pauses. A closer analysis of the pauses revealed that Finnish pupils pause too frequently and in inappropriate places when they speak English. Frequent pausing was also found to cause slow speech rates. The findings of the fundamental frequency (F0) measurements indicate that Finnish pupils tend to make a slightly narrower F0 difference between stressed and unstressed syllables than the native speakers of English. Furthermore, Finnish pupils appear to know how to reduce the duration and quality of unstressed sounds, but they fail to do it frequently enough. Native listeners gave lower intelligibility and attitude scores to pupils with more anomalous speech rhythm. Finnish pupils rhythm anomalies seemed to derive from various learning- or learner-related factors rather than from the differences between English and Finnish. This study demonstrates that pausing may be a more important component of English speech rhythm than sentence stress as far as Finnish adolescents are concerned and that interlanguage development is affected by various factors and characterised by jumps or periods of stasis. Other theoretical, methodological and pedagogical implications of the results are also discussed.
