Frigjord oskuld : heterosexuellt mognadsimperativ i svensk ungdomsroman

För att mogna på en heterosexuell marknad innebär det att unga i ungdomsromanen lär sig förstå hur gränser kan överskridas och vilka handlingar som får repressalier. Genom att diskutera tystnader och talakter gällande heterosexualitet visar "Frigjord oskuld. Heterosexuellt mognadsimperativ i svensk ungdomsroman" hur heteronormen är förhandlingsbar. Studien undersöker heterosexuella kärleksavbrott, gränsöverskridande väninneskap, tabubelagd syskonkärlek och homosexuellt agerande. Med avstamp i queerteori, feministisk teori och narratologi studeras hur sexualitet, men även kategorier som kön, klass och ålder, (re)producerar uppfattningar om (hetero)sexualitet. Utgående från nio ungdomsromaner skrivna år 1969-2004 av fyra författare: Gunnel Beckman, Inger Edelfeldt, Peter Pohl och Mats Wahl analyseras hur de unga förutsätts konstruera heterosexualitet(er) inom ramen för acceptabelt agerande i enlighet med ett heterosexuellt mognadsimperativ.

Kielikylpydidaktiikkaa kehittämässä : 3-6-vuotiaiden kielikylpylasten kielellinen kehitys ja kielikylpydidaktiikan kehittäminen päiväkodissa

The goal of this study is to determine the naming ability in Finnish and Swedish of nursery school-aged children participating in a language immersion programme, as well as their command of both languages. The study also aims to describe factors reflecting language immersion teaching in nursery schools based on action research and a literature survey. The longitudinal study, conducted in 2003–2005, comprised 133 native Finnish three- to six-year-old children in language immersion programmes. A total of four measurements were carried out over two and a half years. In each measurement, four separate tests were given to each child (totally 1134 measurements). Research material was collected using survey tools that measured the children’s naming ability and command of language. The tools had been translated into both Finnish and Swedish. The material also includes taped responses related to the tool for naming ability. Didactic approaches were developed on the basis of material from action research and the literature survey. The material was examined using methodological triangulation, and a quantitative analysis was made of each survey tool. Furthermore, a content analysis of the children’s taped responses gave further depth to the description of language development. The theoretical framework of the study is mainly based on modern sociocultural theories of second language development and acquisition. Thus, the approach is both linguistic and pedagogic, with emphasis lying on the latter. The socioculturally-oriented framework of this study is mainly influenced by the theorists Vygotski, Spolsky, van Lier and Cummins. According to the results, the language skills of children in language immersion programmes develop as expected from age three to six in the fields studied. In the field of language command, the children acquired excellent skills in listening comprehension. Their naming ability was not as good. In each test, the children showed weaker skills in Swedish than in Finnish. However, based on the assumption that the two languages have a shared cognitive field, the skills in Swedish catch up with the skills in Finnish at an annual rate of 6–7 per cent. The study indicates that children meet a language development threshold one year earlier in their native language than they do in the immersion language. As for the naming ability in Swedish, problems arose from the fact that the deviation in results increases with age. Children showed creativity in their use of naming strategies. Judging by the research results, children begin to use the immersion language as a tool for thought at a very early phase. The research results, action research and literature survey were also used to create a general educational model for language immersion.

Under ytan, vid ytan och ovanför ytan : analys av tanken bakom tre läromedel i slöjd

This thesis is based on the personal experience gained related to the planning and production of three web-based teaching materials for the teaching subject knownas sloyd at the comprehensive school in Finland. After the teaching materials had been produced and published on the Internet at the Finnish textile teachers' website KässäBoxi, the idea for this thesis emanated from the questions: Why do the three teaching materials look the way they do and why do other textile teachers comment that they are different? In earlier sloyd educational research it has been stated that a scientific paradigm affects the individual ideology of a sloyd teacher. The aimfor my doctoral thesis is to continue on the topic. As the area of interest comprises the thought behind three teaching materials in sloyd, the aim of the thesis is to show how teaching and educational ideologies in sloyd appear in the teaching materials at hand. The research approach has parallels to research about another, tangible phenomena, namely the iceberg. In a similar way as an iceberg, a teaching material has a profound base, but the base is not always completely visible to the user of the teaching material. In this thesis I strive to show what there is under the surface, on the surface and above the surface of three teaching materials in sloyd. The research approach is defined as qualitative and phenomenologic-hermeneutic. The analysis results in knowledge about how the producer of a teaching material affects the character of a teaching material by choices concerning for example the form, structure, language and illustrations of the teaching material. The analysis also shows how the producers' individual educational and teaching ideologies within the teaching subject at hand appear by means of traces concerning the view on the pupil and the teacher, and the view on planning and conducting teaching in sloyd. The thesis also results in knowledge about how sloyd educational scientific theories and demands from society, as they are stated in the national core curriculum, appear in the three teaching materials. The application of the sloyd educational scientific theory of individual sloyd activity as a holistic educative system is also widened in the thesis. This thesis contributes to future research on producing teaching materials by information about what aspects a producer of teaching materials needs to consider and how the aspects become visible in the teaching materials. This kind of knowledge is valuable to teacher students in sloyd, to teachers in sloyd who intend to plan and produce teaching materials and to teachers who tutor the planning and production of teaching materials.

Enhancing performance of paper coatings by tailor-made plastic pigments

The paper industry is constantly looking for new ideas for improving paper products while competition and raw material prices are increasing. Many paper products are pigment coated. Coating layer is the top layer of paper, thus by modifying coating pigment also the paper itself can be altered and value added to the final product. In this thesis, synthesis of new plastic and hybrid pigments and their performance in paper and paperboard coating is reported. Two types of plastic pigments were studied: core-shell latexes and solid beads of maleimide copolymers. Core-shell latexes with partially crosslinked hydrophilic polymer core of poly(n-butyl acrylate-co-methacrylic acid) and a hard hydrophobic polystyrene shell were prepared to improve the optical properties of coated paper. In addition, the effect of different crosslinkers was analyzed and the best overall performance was achieved by the use of ethylene glycol dimethacrylate (EGDMA). Furthermore, the possibility to modify core-shell latex was investigated by introducing a new polymerizable optical brightening agent, 1-[(4-vinylphenoxy)methyl]-4-(2-henylethylenyl)benzene which gave promising results. The prepared core-shell latex pigments performed smoothly also in pilot coating and printing trials. The results demonstrated that by optimizing polymer composition, the optical and surface properties of coated paper can be significantly enhanced. The optimal reaction conditions were established for thermal imidization of poly(styrene-co-maleimide) (SMI) and poly(octadecene-co-maleimide) (OMI) from respective maleic anhydride copolymer precursors and ammonia in a solvent free process. The obtained aqueous dispersions of nanoparticle copolymers exhibited glass transition temperatures (Tg) between 140-170ºC and particle sizes from 50-230 nm. Furthermore, the maleimide copolymers were evaluated in paperboard coating as additional pigments. The maleimide copolymer nanoparticles were partly imbedded into the porous coating structure and therefore the full potential of optical property enhancement for paperboard was not achieved by this method. The possibility to modify maleimide copolymers was also studied. Modifications were carried out via N-substitution by replacing part of the ammonia in the imidization reaction with amines, such as triacetonediamine (TAD), aspartic acid (ASP) and fluorinated amines (2,2,2- trifluoroethylamine, TFEA and 2,2,3,3,4,4,4-heptafluorobuthylamine, HFBA). The obtained functional nanoparticles varied in size between 50-217 nm and their Tg from 150-180ºC. During the coating process the produced plastic pigments exhibited good runnability. No significant improvements were achieved in light stability with TAD modified copolymers whereas nanoparticles modified with aspartic acid and those containing fluorinated groups showed the desired changes in surface properties of the coated paperboard. Finally, reports on preliminary studies with organic-inorganic hybrids are presented. The hybrids prepared by an in situ polymerization reaction consisted of 30 wt% poly(styrene- co-maleimide) (SMI) and high levels of 70 wt% inorganic components of kaolin and/or alumina trihydrate. Scanning Electron Microscopy (SEM) images and characterization by Fourier Transform Infrared Spcetroscopy (FTIR) and X-Ray Diffraction (XRD) revealed that the hybrids had conventional composite structure and inorganic components were covered with precipitated SMI nanoparticles attached to the surface via hydrogen bonding. In paper coating, the hybrids had a beneficial effect on increasing gloss levels.

L’ambivalence de la femme dans l’oeuvre de Marie Susini

Avhandligen studerar ambivalensen hos kvinnofigurerna i Marie Susinis författarskap från ett socialt och psykologiskt perspektiv. Avhandlingens centrala argument är att Susini som grundläggande ontologisk position för sina kvinnobeskrivningar väljer ett transitionnellt tillstånd: kvinnornas självförverkligande realiseras genom att de skapar sig en identitet via ett utanförskap orsakat av en existentiell ambivalens. De bär på omdevetet formulerade ideal, är kluvna av dilemman och deras handlingar kännetecknas av motstridiga principer, önskningar och strävanden. I avhandlingen granskas ambivalensens uttrycksformer från barndomen till vuxenlivet. Det karakteristiska för barnen och de unga kvinnorna är att deras ambivalens är sammankopplad med deras socialiseringsprocess. Deras dilemma består i att utröna vilka beteenden, attityder och värderingar det är legitimt att imitera, eftersom de sociala normerna står i konflikt med varandra och de ungas förväntningar. I parförhållanden vacklar kvinnorna mellan två motsatta sociala positioner: en kvinna som är engagerad i sitt förhållande och en emanciperad kvinna som väljer att leva ensam. Den här ambivalenta inställningen bidrar till ett misslyckande på det affektiva planet. Beträffade modern finns dels den korsikanska mamman, sträng och okänslig, men som under ytan brottas med frågeställningar som är förknippade med bl.a. sina döttrars kroppslighet. De här mödrarna konfronteras med den sociala ambivalens som uppstod vid brytningspunkten i Korsikas historia då traditionella värderingar gav vika för moderna influenser utifrån. Dels finns mödrar som är frigjorda kvinnor och som i sin frihet väljer bort mödraskapet. Texternas interna struktur återspeglar den klyvning som sliter kvinnorna: tidsperspektivet är fragementariskt och icke-kronologiskt och berättarrösterna växlar, vilket gör att läsaren samtidigt både identifierar sig med och distanserar sig från det som berättas. Metatextuella referenser signalerar å sin sida att Susini hämtar sin inspiration från sitt eget liv.

Toimiiko turvallisuus- ja puolustuspoliittinen selontekomenettely?

Selontekomenettely on linjannut Suomen turvallisuus- ja puolustuspolitiikkaa 1990-luvun puolivälistä alkaen. Selonteon asema linjanvetäjänä ja poliittisen tahdonilmaisun välineenä on samalla merkinnyt kasvanutta halua vaikuttaa sen sisältöön, etenkin laajennetun turvallisuuskäsityksen ja avartuneen keskusteluilmapiirin myötä. Selontekomenettelyssä on kyse yhdestä mahdollisesta mallista, jolla turvallisuus- ja puolustuspoliittisia linjauksia voidaan tehdä. Tässä kirjoituksessa tarkastellaan nykyisen menettelytavan toimivuutta ja pohditaan kolmea eri vaihtoehtoa tälle vakiintuneelle toimintatapamallille.
