Makt, konst, elit - konstfältets positioner, relationer och resurser i 1940- och 1950-talens Helsingfors

The dissertation examines the power mechanisms and institutional power hierarchies of the 1940s-1950s era arts elite in Helsinki and their influence on issues of taste in the visual arts. For the purposes of this study, the elite is understood to consist mainly of the board members of the principal elected bodies in the field of the arts. The theoretical framework employed is based on Pierre Bourdieu s field theory and the network perspective. The author has examined what the key, pervasive valuations were that governed the exercising of power by the arts elite in issues of taste, involving determination of who was an acknowledged artist and what was good art. The dissertation demonstrates that this exercising of power was governed by certain collective practices which maintained the illusion that the exercising of power was democratic and based on artistic quality. These practices were the corporate system, using artistic arguments in issues of taste, and using networks in the exercising of power. The struggle in the field of the arts was about who ultimately was entitled to define the value of contemporary art; the issue did not arise regarding historical art. Artists managed to gain a leading position as gatekeepers in issues regarding contemporary art. The author discusses a number of conflicts in the field of the arts that highlight the institutional hierarchies and the capital held by the various players. The structural changes that occurred in administration in the field of cultural production in the 1950s led to the separation of bureaucratic competence on the one hand and aesthetic competence on the other. There was a hierarchy in the field of the arts between institutions, between instruments of legitimisation, and between the symbolic and social capital of players in the field. The hierarchy in the arts ultimately depended on how well the elite could influence tastes through the instruments at their disposal. The various instruments of legitimisation grants, purchases, etc. were ranked differently in the evaluation of acknowledged artists and good art. The dissertation discusses what values, in the form of types of symbolic capital, the arts elite embraced and what role these played in the elite s exercising of power, with particular focus on gender, language, region and economic capital. The aesthetic capital of an artist was of only minor importance in the exercising of power by the arts elite. The dissertation further discusses the points of contact between the arts elite and players in other fields, such as the economic, media and consumer fields. When the arts elite, through the Academy of Fine Arts, became an active player in the art market, this led to a hierarchy where the division between acknowledged and not-acknowledged galleries became sharper.

Molecular mechanisms of bacteriophage phi6 RNA-dependent RNA polymerase and its utilization in biotechnology

Double-stranded RNA (dsRNA) viruses encode only a single protein species that contains RNA-dependent RNA polymerase (RdRP) motifs. This protein is a central component in the life cycle of a dsRNA virus, carrying out both RNA transcription and replication. The architecture of viral RdRPs resembles that of a 'cupped right hand' with fingers, palm and thumb domains. Those applying de novo initiation have additional structural features, including a flexible C-terminal domain that constitutes the priming platform. Moreover, viral RdRPs must be able to interact with the incoming 3'-terminus of the template and position it so that a productive binary complex is formed. Bacteriophage phi6 of the Cystoviridae family is to date one of the best studied dsRNA viruses. The purified recombinant phi6 RdRP is highly active in vitro and possesses both RNA replication and transcription activities. The extensive biochemical observations and the atomic level crystal structure of the phi6 RdRP provides an excellent platform for in-depth studies of RNA replication in vitro. In this thesis, targeted structure-based mutagenesis, enzymatic assays and molecular mapping of phi6 RdRP and its RNA were used to elucidate the formation of productive RNA-polymerase binary complexes. The positively charged rim of the template tunnel was shown to have a significant role in the engagement of highly structured ssRNA molecules, whereas specific interactions further down in the template tunnel promote ssRNA entry to the catalytic site. This work demonstrated that by aiding the formation of a stable binary complex with optimized RNA templates, the overall polymerization activity of the phi6 RdRP can be greatly enhanced. Furthermore, proteolyzed phi6 RdRPs that possess a nick in the polypeptide chain at the hinge region, which is part of the extended loop, were better suited for catalysis at higher temperatures whilst favouring back-primed initiation. The clipped C-terminus remains associated with the main body of the polymerase and the hinge region, although structurally disordered, is involved in the control of C-terminal domain displacement. The accumulated knowhow on bacteriophage phi6 was utilized in the development of two technologies for the production of dsRNA: (i) an in vitro system that combines the T7 RNA polymerase and the phi6 RdRP to generate dsRNA molecules of practically unlimited length, and (ii) an in vivo RNA replication system based on restricted infection with phi6 polymerase complexes in bacterial cells to produce virtually unlimited amounts of dsRNA. The pools of small interfering RNAs derived from dsRNA produced by these systems were validated and shown to efficiently decrease the expression of both exogenous and endogenous targets.

Rättsekonomisk analys av revisors skadeståndsansvar i Norden

Revisorn utför ekonomisk kontroll inom sitt uppdrag. Ett vållande av ekonomisk skada när revisorn utför uppdraget innebär att han kan åläggas skadeståndsansvar. På senare tid har revisors vållande vid ekonomisk kontroll prövats av de högsta rättsinstanserna i de nordiska länderna. De högsta rättsinstanserna tenderar att gå långt i sina bedömningar om revisors vållande av ekonomisk skada. De ställer ofta aktsamhetskravet högt då de ålägger revisorerna skadeståndsansvar. I avhandlingen testas revisors skadeståndsansvar enligt en i undersökningen uppbyggd ekonomisk modell. Målsättningen är att vållanderegeln skall leda till ekonomisk effektivitet. Ekonomisk effektivitet prövas genom att en ekonomisk avvägning mellan nyttan och kostnaden med att företa skadeförebyggande åtgärder görs. I den ekonomiska analysen beskrivs revisors vållande i termer av revisors bristande omsorg, medan revisors grova vållande beskrivs som uppenbar försummelse. För undersökningen utgör det nordiska rättsfallsmaterialet ett material där strukturen är likadan, vilket gör det möjligt att pröva ekonomisk effektivitet. Resultatet av den ekonomiska analysen visar att ersättning för förmögenhetsskador inte skall utgöra den egentliga målsättningen. För att kunna begränsa omfattningen av revisors ersättningsansvar så att det ur en samhällsekonomisk synvinkel är ekonomiskt effektivt, bör det formuleras en snäv bedömningsgrund för revisors bristande omsorg. Den ekonomiska analysen påvisar att revisorerna vid bristande omsorg bör åläggas ett administrativt ansvar i form av disciplinära åtgärder. Revisorer skall åläggas skadeståndsansvar endast vid uppenbar försummelse. Genom uppenbar försummelse underlåter revisorerna att förebygga uppenbar förutsebar skada och åsidosätter sitt professionsansvar på ett medvetet sätt.

Wirtschaftssprache deutsch in studium und beruf - curriculumentwicklung an der schwedischen wirtschaftsuniversität in Finnland.

An der Schwedischen Wirtschaftsuniversität in Finnland wurde in einem mehrjährigen Projekt das gesamte deutsche Sprachcurriculum einer grundlegenden Revision unterzogen mit dem Ziel, unter Berücksichtigung der neuesten Forschungsergebnisse der angewandten Sprachwissenschaft ein zeitgemäßes und konsistentes Deutschcurriculum für Studierende der Wirtschaftswissenschaften zu schaffen. Durch das Projekt wurde für die deutsche Sprachausbildung ein deutliches Profil geschaffen, dessen Fokus auf fachkommunikativer Kompetenz und interkultureller Geschäftskommunikation liegt. Die von der Deutschabteilung entwickelten Lehr- und Lernmaterialien sind weitgehend auf der Basis eigener Forschungsergebnisse konzipiert und evaluiert worden und wurden gleichzeitig an den Gemeinsamen europäischen Referenzrahmens für Sprachen (CEFR) angepasst.

Diversitet och tillväxtfrämjande egenskaper hos Stenotrophomonas-endofyter isolerade från Calliandra calothyrsus Meisn. rotknölar

The bacterial genus Stenotrophomonas comprises 12 species. They are widely found throughout the environment and particularly S. maltophilia, S. rhizophila and S. pavanii are closely associated with plants. Strains of the most common Stenotrophomonas species, S. maltophilia, promote plant growth and health, degrade natural and man-made pollutants and produce biomolecules of biotechnological and economical value. Many S. maltophilia –strains are also multidrug resistant and can act as opportunistic human pathogens. During an INCO-project (1998-2002) rhizobia were collected from root nodules of the tropical leguminous tree Calliandra calothyrsus Meisn. from several countries in Central America, Africa and New Caledonia. The strains were identified by the N2-group (Helsinki university) and some strains turned out to be members of the genus Stenotrophomonas. Several Stenotrophomonas strains induced white tumor- or nodule-like structures on Calliandra?s roots in plant experiments. The strains could, besides from root nodules, also be isolated from surface sterilized roots and stems. The purpose of my work was to investigate if the Stenotrophomonas strains i) belong to a new Stenotrophomonas species, ii) have the same origin, iii) if there are other differences than colony morphology between phase variations of the same strain, iv) have plant growth-promoting (PGP) activity or other advantageous effects on plants, and v) like rhizobia have ability to induce root nodule formation. The genetic diversity and clustering of the Stenotrophomonas strains were analyzed with AFLP fingerprinting to get indications about their geographical origin. Differences in enzymatic properties and ability to use different carbon and energy sources were tested between the two phases of each strain with commercial API tests for bacterial identification. The ability to infect root hairs and induce root nodule formation was investigated both using plant tests with the host plant Calliandra and PCR amplification of nodA and nodC genes for nodulation. The PGP activity of the strains was tested in vitro mainly with plate methods. The impact on growth, nitrogen content and nodulation in vivo was investigated through greenhouse experiments with the legumes Phaseolus vulgaris and Galega orientalis. Both the genetic and phenotypic diversity among the Stenotrophomonas strains was small, which proposes that they have the same origin. The strains brought about changes on the root hairs of Calliandra and they also increased the amount of root hairs. However, no root nodules were detected. The strains produced IAA, protease and lipase in vitro. They also showed plant a growth-promoting effect on G. orientalis, both alone and together with R. galegae HAMBI 540, and also activated nodulation among efficient rhizobia on P. vulgaris in greenhouse. It requires further research to get a better picture about the mechanisms behind the positive effects. The results in this thesis, however, confirm earlier studies concerning Stenotrophomonas positive impact on plants.

Det grekiska dramat. En Studie av euroländeras agerande i Greklandskrisen.

Jag granskar i min avhandling pro gradu den ekonomiska krisen i Grekland som kulminerade under vären 2010 när Grekland vände sig tili de övriga medlemsländerna i Ekonomiska och monetära Unionen (EMU) med en förfrägan om ekonomisk hjälp i formav län. Syftet med avhandlingen är att undersöka hur de övriga EMU-medlemmarna fattade sitt beslut om att ekonomiskt stöda Grekland efter att landets kreditvärdighet sänkts av de internationella kreditvärderingsinstituten. Jag granskar Greklandskrisen och dess utveckling, de lösningar som man gick in för inom ramen för valutaunionen, hur besluten om stödpaketet fattades och vilka faktorer som päverkade besluten. Jag tar avstamp i Optimum Currency Area-teorin (OCA-teorin) och teorier om europeisk ekonomisk integration. Dessutom för jag en diskussion kring solidariteten mellan EUländerna, som ocksä använts som argument för stödpaketet tili Grekland. Jag klassificerar euroländerna utgäende för hur det nationella beslutet om Greklandspaketet fattats och gör därefter en agglomerativ klusteranalys, med ambitionen att förklara vilka faktorer som päverkat besluten. Syftet med klusteranalysen är att klargöra huruvida politiska faktorer, som härrör sig tili regeringen och dess sammansättning, eller ekonomiska faktorer, som bclyser statsfinansernas tillständ, bäst förklarar hur ett land fattat sitt beslut. Resultatet visar att de politiska variablerna har päverkat ländernas beslut mer an de ekonomiska, men förklaringsgraden är relativt lag i bägge fallen. Jag för vidare en diskussion om resultatet ur ett OCA-perspektiv, kriterierna för ett optimalt valutaomräde samt EMU:s utveckling i dito riktning. Jag avslutar avhandlingen med en diskussion kring EMU:s framtid.
