Syftet med denna studie är att genom data-analys triangulation undersöka socionomstuderandes svar på ett yrkesetiskt dilemma av omsorgsetisk natur. Samplet består av 32 socionomer i början av sina studier som har svarat på ett hypotetiskt dilemma om hur de skulle bemöta en ung kvinna som ber om råd i en mycket svår situation. De huvudsakliga teoretiska utgångspunkterna för detta arbete är ECI (Ethic of Care Interview) som utvecklats av Eva Skoe som metod för att undersöka omsorgsetik, samt Osers och Althofs teori om diskursiva problemlösningsmetoder bland professionella. Som grundläggande teorier för all modern forskning om människans moralutveckling, presenteras också Carol Gilligans och Lawrence Kohlbergs teorier samt den huvudsakliga kritiken dessa bemött. Carol Gilligan är den som ursprungligen presenterade tanken om att det finns två olika typer av moraliskt tänkande där omsorgsetik är mer typisk för kvinnor och rättviseetik är mer typisk för män. Den första delen av analysen är en innehållsanalys där svaren på det yrkesrelaterade dilemmat på olika ECI stadium jämförs med varandra. Poängsättningen i ECI har varit grunden för denna analys. Den andra delen av analysen är en deduktiv teoribunden analys, där jag undersökt i fall Osers och Althofs modell om problemlösningsstrategier även går att tillämpa på ett yrkesetiskt dilemma. Slutligen tar jag också ställning till dessa två teoriers kompatibilitet. Resultatet visar att eleverna har svarat aningen sämre på det yrkesetiska dilemmat än vad deras allmänna ECI stadium är. Detta kan bero på att de är i början av sina studier men också på det allmänna klimat som råder inom socialbranschen. Teorin om diskursiva problemlösningsstrategier går inte heller att tillämpa på detta yrkesetiska dilemma, eftersom den hypotetiska klientens självbestämmanderätt gör en diskursiv lösning omöjlig. Till följd av detta har jag skapat en ny modell som baserar sig på 6 kategorier utgående från de faktorer de intervjuade lyfter fram som de viktigaste i den professionellas möte med klienten. Eftersom den nya modellen inte är hierarkisk, kan de två teorierna inte jämföras med varandra på så sätt att högre ECI nivå skulle innebära en viss typ av problemlösningsstrategi.

Understanding the responses of species and ecosystems to human-induced global environmental change has become a high research priority. The main aim of this thesis was to investigate how certain environmental factors that relate to global change affect European aspen (Populus tremula), a keystone species in boreal forests, and hybrid aspen (P. tremula × P. tremuloides), cultivated in commercial plantations. The main points under consideration were the acclimatization potential of aspen through changes in leaf morphology, as well as effects on growth, leaf litter chemistry and decomposition. The thesis is based on two experiments, in which young aspen (< 1 year) were exposed either to an atmospheric pollutant [elevated ozone (O3)] or variable resource availability [water, nitrogen (N)]; and two field studies, in which mature trees (> 8 years) were growing in environments exposed to multiple environmental stress factors (roadside and urban environments). The field studies included litter decomposition experiments. The results show that young aspen, especially the native European aspen, was sensitive to O3 in terms of visible leaf injuries. Elevated O3 resulted in reduced biomass allocation to roots and accelerated leaf senescence, suggesting negative effects on growth in the long term. Water and N availability modified the frost hardening of young aspen: High N supply, especially when combined with drought, postponed the development of frost hardiness, which in turn may predispose trees to early autumn frosts. This effect was more pronounced in European aspen. The field studies showed that mature aspen acclimatized to roadside and urban environments by producing more xeromorphic leaves. Leaf morphology was also observed to vary in response to interannual climatic variation, which further indicates the ability of aspen for phenotypic plasticity. Intraspecific variation was found in several of the traits measured, although intraspecific differences in response to the abiotic factors examined were generally small throughout the studies. However, some differences between clones were found in sensitivity to O3 and the roadside environment. Aspen leaf litter decomposition was retarded in the roadside environment, but only initially. By contrast, decomposition was found to be faster in the urban than the rural environment throughout the study. The higher quality of urban litter (higher in N, lower in lignin and phenolics), as well as higher temperature, N deposition and humus pH at the urban site were factors likely to promote decay. The phenotypic plasticity combined with intraspecific variation found in the studies imply that aspen has potential for withstanding environmental changes, although some global change factors, such as rising O3 levels, may adversely affect its performance. The results also suggest that the multiple environmental changes taking place in urban areas which correspond closely with the main drivers of global change can modify ecosystem functioning by promoting litter decomposition, mediated partly by alterations in leaf litter quality.

This dissertation is an onomastic study of variation in women s name phrases in official documents in Finland during the period 1780−1930. The aim is to discuss from a socio-onomastic perspective both the changeover from patronymics to inherited family names and the use of surnames after marriage (i.e. whether women adopted their husbands family names or retained their maiden names), before new laws in this area entered into force in Finland in the early 20th century. In 1920, a law on family names that required fixed names put an end to the use of the patronymic as a person s only surname. After 1929, it was no longer possible for a married woman to retain her maiden name. Methodologically, to explain this development from a socio-onomastic perspective, I have based my study on a syntactic-semantic analysis of the actual name phrases. To be able to demonstrate the extensive material, I have elaborated a scheme to divide the 115 different types of name phrases into 13 main categories. The analysis of the material for Helsinki is based on frequency calculations of the different types of name phrases every thirtieth year, as well as on describing variation in the structure and semantic content of the name phrases, e.g. social variation in the use of titles and epithets. In addition to this, by applying a biographic-genealogical method, I have conducted two case studies of the usage of women s name phrases in the two chosen families. The study is based on parish registers from the period 1780−1929, estate inventory documents from the period 1780−1928, registration forms for liberty of trade from the period 1880−1908, family announcements on newspapers from the period 1829−1888, gravestones from the period 1796−1929 and diaries from the periods 1799−1801 and 1818−1820 providing a corpus of 5 950 name phrases. The syntactic-semantic analysis has revealed the overall picture of various ways of denoting women in official documents. In Helsinki, towards the end of the 19th century, the use of inherited family names seems to be almost fully developed in official contexts. At the late 19th century, a patronymic still appears as the only surname of some working-class women whereas in the early 20th century patronymics were only entered in the parish register as a kind of middle name. In the beginning of the 19th century, most married women were still registered under their maiden names, with a few exceptions among the bourgeoisie and upper class. The comparative analysis of name phrases in diaries, however, indicates that the use of the husband s family name by married women was a much earlier phenomenon in private contexts than in official documents.
