Medieberättelser om den politiska retoriken om invandring - Hur konstrueras vår bild av invandring genom nyhetsrapportering?

I min pro gradu-avhandling undersöker jag hur media bidrar till att konstruera bilden av invandring till Finland. Mitt material består av tre nationella tidningar, varav Helsingin Sanomat och Huvudstadsbladet representerar dagstidningar och Iltalehti kvällspressen. Bakgrunden för undersökningen är en tre månaders period under vintern 2008-2009, då invandring låg högt på den politiska agendan. Under denna period skärptes den politiska retoriken mot invandring. Detta tillskrivs främst sannfinländarnas valframgång i kommunalvalet hösten 2008. Materialet består av s.k. hårda nyheter om invandring från tidningarnas inrikessidor samt åsiktsjournalistik i form av ledare och kolumner. Tidigare forskning i medierapportering om invandring och den finländska politiska debatten om invandring utgör den teoretiska bakgrunden för avhandlingen. Långvariga kartläggningsprojekt av medierapporteringen om invandring har utförts av Centret för forskning om etniska relationer och nationalism, gällande finlandssvenska tidningar (se Haavisto 2007) och av Journalismin tutkimuskeskus, gällande finskspråkiga tidningar (se Raittila & Vehmas 2005). Dessa utgör bakgrundskunskap som jag bygger vidare på. Andra viktiga källor är Kaarina Horstis (2005) avhandling, som handlar om medierapporteringen om asylsökande och mångkulturalism och Outi Lepolas (2008) avhandling gällande riksdagsdebatter om invandring och mångkulturalism på 1990-talet. I analysen använder jag kritisk diskursanalys, men tar inslag ur ramanalys och retorikanalys. Ett centralt begrepp i min avhandling är nyhetsgenre och jag undersöker hur nyhetens konventioner påverkar sättet på vilket frågor om invandring presenteras. Media bygger upp olika tolkningar av den sociala verkligheten genom att beskriva berättelser. Jag analyserar rapporteringen av den politiska debatten ur detta perspektiv och ser på vilka talarpositioner ges åt de olika politiska aktörerna i debatten. I rapporteringen om invandrargruppers ankomst till Finland var en krisinramning dominerande. Genom negativa metaforer konstrueras invandring som ett hot mot det finska samhället. Frågan om asylsökande, framom andra invandrargrupper, får mycket utrymme i tidningarna och bidrar till att rama in diskussionen om invandring i stort. I rapporteringen om den politiska debatten från perioden förekommer tillspetsad retorik mot invandring också från politiker ur de stora partierna. Genom denna retorik konstruerar man invandring som ett hot. Denna retorik tillhör den invandrarkritiska diskursen. Andra diskurser genom vilka man behandlar invandring i materialet är den arbetsrelaterade diskursen och den mångkulturella diskursen. Argument som stödjer sig mot dessa diskurser är dock mycket färre och hamnar i skymundan av den invandrarkritiska diskursen.

Modernismens förespråkare : Gösta Stenman och hans konstsalong

This dissertation, based on material from Stenman s vast private archive, examines the role played by Swedish-speaking Finnish art dealer Gösta Stenman (1888-1947) and his art gallery, Stenmans Konstsalong, in the Finnish and Swedish art worlds from 1911 to 1947. This archive is examined here for the first time. The analytical framework used for this empirical study derives from Pierre Bourdieu s sociological theories. An art-sociological approach allows for the inclusion of more mechanisms at work in the art world than are typically embraced in such inquiries. This approach provides a fuller understanding of how Stenman attained his standing and central role in the art world in Finland as well as Sweden; enabling us to appreciate how he came to occupy such a prominent position in current art historical writing. All of these issues constitute new areas of research. Taking his cues from the contemporary art world of Paris, Stenman became the year 1914 a modern art dealer like no other in the Nordic countries. This dissertation represents the first academic investigation into his operations, strategies, and objectives, offering insight into not only the art dealer himself but also the functioning of the art market one of the most vital aspects of the art world. A by-product of this work, is that the modern art market in Finland is portrayed, including essential issues related to its growth and development as well as how it altered the conditions under which art could be produced, exhibited and promoted and what this entailed for the art world at large, artists and patrons alike. This first systematic analysis of the operations of Stenman s Konstsalong offers greater understanding of the art worlds of Sweden and Finland in the early twentieth century. The work also looks at how an agent of the art market could move between the fields of art in Sweden and Finland. The manner in which Stenman promoted individual artists, including his relationships with Tyko Sallinen, Helene Schjerfbeck, Juho Mäkelä, Jalmari Ruokokoski, Siri Derkert, Esther Kjerner, Eva Bagge, and many others, also falls within this purview. Stenman s contract with Sallinen from 1913 stands out as a new phenomenon in Finnish art promotion, whereby an artistic career became established via a far-sighted, strategic promotional program. The case study of Stenman s promotion of Schjerfbeck in Sweden provides evidence of the increasingly advanced nature of Stenman s strategies. The title of the dissertation, The Promoter of Modernism, attempts to convey that Stenman was the consummate modernist, modern in his thoughts, his actions, and his approach to art. Keywords: Gösta Stenman, Stenmans konstsalong, Stenmans dotter, art market, modernism, collecting, Novembergruppen, Helene Schjerfbeck, Tyko Sallinen, Juho Mäkelä, Jalmari Ruokokoski, Wäinö Aaltonen, Siri Derkert, Åke Göransson, Esther Kjerner, Eva Bagge.

Idyll eller verklighet? : Albert Edelfelt och Gunnar Berndtson i det moderna genombrottets ambivalens

Idyll or Reality? Albert Edelfelt, Gunnar Berndtson and the ambivalent breakthrough of modernity Albert Edelfelt (1854-1905) and Gunnar Berndtson (1854-1895) have much in common. In this dissertation, I study their paintings of local peasants and fishermen and of the gentry’s summer in the county of Uusimaa in southern Finland, in the context of Nordic history of ideas. The breakthrough of modernity, with its attention on debating social problems, provides a novel angle into the oeuvres of the two artists. My focus is on the paintings which emerge in the collision of the public discussion of social matters and the values of the artists’ manorial milieu. The artists’ relation to the public discussion is scrutinized through two of the main topics: the question of the common people and democracy, and the question of equality between men and women. My dissertation is a contextual study which is based on the analysis of the artworks of Edelfelt and Berndtson, on their letters, and on the study of drama and fiction of their time. The notion “liberté, egalité, fraternité” is linked to the breakthrough of modernity. Both artists were aware of the ideal of equality. They used the means and the themes of contemporary art in their presentations, but their pictures contain the ideal of an earlier epoch: the hardworking, but still complacent common people. This conception of the common people is also reflected in the poems of J. L. Runeberg. Women of the late 19th century challenged woman’s primary role as wife and mother. In Edelfelt’s and Berndtson’s depictions of the gentry enjoying summer, women and children have the main role. Notwithstanding the debate of the breakthrough of modernity they depicted women almost without exception as good mothers. Their paintings often depict lazy days in the sunshine, which were, in reality, rare moments for the mistress of the house. Edelfelt’s and Berndtson’s subjects from the Uusimaa countryside coincide with the topics of the breakthrough of modernity, but both the pictures of the common people and the depictions of the gentry enjoying summer, are a retouched picture of reality, often an idyll, in which the public discussion of social matters is evident only materially or not at all.

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

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.

Damp building moulds: Assessment of sensitization in patients and studies into mechanisms of airway inflammation using experimental models

Exposure to water-damaged buildings and the associated health problems have evoked concern and created confusion during the past 20 years. Individuals exposed to moisture problem buildings report adverse health effects such as non-specific respiratory symptoms. Microbes, especially fungi, growing on the damp material have been considered as potential sources of the health problems encountered in these buildings. Fungi and their airborne fungal spores contain allergens and secondary metabolites which may trigger allergic as well as inflammatory types of responses in the eyes and airways. Although epidemiological studies have revealed an association between damp buildings and health problems, no direct cause-and-effect relationship has been established. Further knowledge is needed about the epidemiology and the mechanisms leading to the symptoms associated with exposure to fungi. Two different approaches have been used in this thesis in order to investigate the diverse health effects associated with exposure to moulds. In the first part, sensitization to moulds was evaluated and potential cross-reactivity studied in patients attending a hospital for suspected allergy. In the second part, one typical mould known to be found in water-damaged buildings and to produce toxic secondary metabolites was used to study the airway responses in an experimental model. Exposure studies were performed on both naive and allergen sensitized mice. The first part of the study showed that mould allergy is rare and highly dependent on the atopic status of the examined individual. The prevalence of sensitization was 2.7% to Cladosporium herbarum and 2.8% to Alternaria alternata in patients, the majority of whom were atopic subjects. Some of the patients sensitized to mould suffered from atopic eczema. Frequently the patients were observed to possess specific serum IgE antibodies to a yeast present in the normal skin flora, Pityrosporum ovale. In some of these patients, the IgE binding was partly found to be due to binding to shared glycoproteins in the mould and yeast allergen extracts. The second part of the study revealed that exposure to Stachybotrys chartarum spores induced an airway inflammation in the lungs of mice. The inflammation was characterized by an influx of inflammatory cells, mainly neutrophils and lymphocytes, into the lungs but with almost no differences in airway responses seen between the satratoxin producing and non-satratoxin producing strain. On the other hand, when mice were exposed to S. chartarum and sensitized/challenged with ovalbumin the extent of the inflammation was markedly enhanced. A synergistic increase in the numbers of inflammatory cells was seen in BAL and severe inflammation was observed in the histological lung sections. In conclusion, the results in this thesis imply that exposure to moulds in water damaged buildings may trigger health effects in susceptible individuals. The symptoms can rarely be explained by IgE mediated allergy to moulds. Other non-allergic mechanisms seem to be involved. Stachybotrys chartarum is one of the moulds potentially responsible for health problems. In this thesis, new reaction models for the airway inflammation induced by S. chartarum have been found using experimental approaches. The immunological status played an important role in the airway inflammation, enhancing the effects of mould exposure. The results imply that sensitized individuals may be more susceptible to exposure to moulds than non-sensitized individuals.

Understanding the chemistry of atmospheric aerosol particle formation via observations of physical properties

It is widely accepted that the global climate is heating up due to human activities, such as burning of fossil fuels. Therefore we find ourselves forced to make decisions on what measures, if any, need to be taken to decrease our warming effect on the planet before any irrevocable damage occurs. Research is being conducted in a variety of fields to better understand all relevant processes governing Earth s climate, and to assess the relative roles of anthropogenic and biogenic emissions into the atmosphere. One of the least well quantified problems is the impact of small aerosol particles (both of anthropogenic and biogenic origin) on climate, through reflecting solar radiation and their ability to act as condensation nuclei for cloud droplets. In this thesis, the compounds driving the biogenic formation of new particles in the atmosphere have been examined through detailed measurements. As directly measuring the composition of these newly formed particles is extremely difficult, the approach was to indirectly study their different characteristics by measuring the hygroscopicity (water uptake) and volatility (evaporation) of particles between 10 and 50 nm. To study the first steps of the formation process in the sub-3 nm range, the nucleation of gaseous precursors to small clusters, the chemical composition of ambient naturally charged ions were measured. The ion measurements were performed with a newly developed mass spectrometer, which was first characterized in the laboratory before being deployed at a boreal forest measurement site. It was also successfully compared to similar, low-resolution instruments. The ambient measurements showed that sulfuric acid clusters dominate the negative ion spectrum during new particle formation events. Sulfuric acid/ammonia clusters were detected in ambient air for the first time in this work. Even though sulfuric acid is believed to be the most important gas phase precursor driving the initial cluster formation, measurements of the hygroscopicity and volatility of growing 10-50 nm particles in Hyytiälä showed an increasing role of organic vapors of a variety of oxidation levels. This work has provided additional insights into the compounds participating both in the initial formation and subsequent growth of atmospheric new aerosol particles. It will hopefully prove an important step in understanding atmospheric gas-to-particle conversion, which, by influencing cloud properties, can have important climate impacts. All available knowledge needs to be constantly updated, summarized, and brought to the attention of our decision-makers. Only by increasing our understanding of all the relevant processes can we build reliable models to predict the long-term effects of decisions made today.

Interatomic potentials for fusion reactor material simulations

Fusion energy is a clean and safe solution for the intricate question of how to produce non-polluting and sustainable energy for the constantly growing population. The fusion process does not result in any harmful waste or green-house gases, since small amounts of helium is the only bi-product that is produced when using the hydrogen isotopes deuterium and tritium as fuel. Moreover, deuterium is abundant in seawater and tritium can be bred from lithium, a common metal in the Earth's crust, rendering the fuel reservoirs practically bottomless. Due to its enormous mass, the Sun has been able to utilize fusion as its main energy source ever since it was born. But here on Earth, we must find other means to achieve the same. Inertial fusion involving powerful lasers and thermonuclear fusion employing extreme temperatures are examples of successful methods. However, these have yet to produce more energy than they consume. In thermonuclear fusion, the fuel is held inside a tokamak, which is a doughnut-shaped chamber with strong magnets wrapped around it. Once the fuel is heated up, it is controlled with the help of these magnets, since the required temperatures (over 100 million degrees C) will separate the electrons from the nuclei, forming a plasma. Once the fusion reactions occur, excess binding energy is released as energetic neutrons, which are absorbed in water in order to produce steam that runs turbines. Keeping the power losses from the plasma low, thus allowing for a high number of reactions, is a challenge. Another challenge is related to the reactor materials, since the confinement of the plasma particles is not perfect, resulting in particle bombardment of the reactor walls and structures. Material erosion and activation as well as plasma contamination are expected. Adding to this, the high energy neutrons will cause radiation damage in the materials, causing, for instance, swelling and embrittlement. In this thesis, the behaviour of a material situated in a fusion reactor was studied using molecular dynamics simulations. Simulations of processes in the next generation fusion reactor ITER include the reactor materials beryllium, carbon and tungsten as well as the plasma hydrogen isotopes. This means that interaction models, {\it i.e. interatomic potentials}, for this complicated quaternary system are needed. The task of finding such potentials is nonetheless nearly at its end, since models for the beryllium-carbon-hydrogen interactions were constructed in this thesis and as a continuation of that work, a beryllium-tungsten model is under development. These potentials are combinable with the earlier tungsten-carbon-hydrogen ones. The potentials were used to explain the chemical sputtering of beryllium due to deuterium plasma exposure. During experiments, a large fraction of the sputtered beryllium atoms were observed to be released as BeD molecules, and the simulations identified the swift chemical sputtering mechanism, previously not believed to be important in metals, as the underlying mechanism. Radiation damage in the reactor structural materials vanadium, iron and iron chromium, as well as in the wall material tungsten and the mixed alloy tungsten carbide, was also studied in this thesis. Interatomic potentials for vanadium, tungsten and iron were modified to be better suited for simulating collision cascades that are formed during particle irradiation, and the potential features affecting the resulting primary damage were identified. Including the often neglected electronic effects in the simulations was also shown to have an impact on the damage. With proper tuning of the electron-phonon interaction strength, experimentally measured quantities related to ion-beam mixing in iron could be reproduced. The damage in tungsten carbide alloys showed elemental asymmetry, as the major part of the damage consisted of carbon defects. On the other hand, modelling the damage in the iron chromium alloy, essentially representing steel, showed that small additions of chromium do not noticeably affect the primary damage in iron. Since a complete assessment of the response of a material in a future full-scale fusion reactor is not achievable using only experimental techniques, molecular dynamics simulations are of vital help. This thesis has not only provided insight into complicated reactor processes and improved current methods, but also offered tools for further simulations. It is therefore an important step towards making fusion energy more than a future goal.

Good Lives, Hidden Miseries : An Ethnography of Uncertainty in a Finnish Village

This is an ethnographic study, in the field of medical anthropology, of village life among farmers in southwest Finland. It is based on 12 months of field work conducted 2002-2003 in a coastal village. The study discusses how social and cultural change affects the life of farmers, how they experience it and how they act in order to deal with the it. Using social suffering as a methodological approach the study seeks to investigate how change is related to lived experiences, idioms of distress, and narratives. Its aim has been to draw a locally specific picture of what matters are at stake in the local moral world that these farmers inhabit, and how they emerge as creative actors within it. A central assumption made about change is that it is two-fold; both a constructive force which gives birth to something new, and also a process that brings about uncertainty regarding the future. Uncertainty is understood as an existential condition of human life that demands a response, both causing suffering and transforming it. The possibility for positive outcomes in the future enables one to understand this small suffering of everyday life both as a consequence of social change, which fragments and destroys, and as an answer to it - as something that is positively meaningful. Suffering is seen to engage individuals to ensure continuity, in spite of the odds, and to sustain hope regarding the future. When the fieldwork was initiated Finland had been a member of the European Union for seven years and farmers felt it had substantially impacted on their working conditions. They complained about the restrictions placed on their autonomy and that their knowledge was neither recognised, nor respected by the bureaucrats of the EU system. New regulations require them to work in a manner that is morally unacceptable to them and financial insecurity has become more prominent. All these changes indicate the potential loss of the home and of the ability to ensure continuity of the family farm. Although the study initially focused on getting a general picture of working conditions and the nature of farming life, during the course of the fieldwork there was repeated mention of a perceived high prevalence of cancer in the area. This cancer talk is replete with metaphors that reveal cultural meanings tied to the farming life and the core values of autonomy, endurance and permanence. It also forms the basis of a shared identity and a means of delivering a moral message about the fragmentation of the good life; the loss of control; and the invasion of the foreign. This thesis formed part of the research project Expressions of Suffering. Ethnographies of Illness Experiences in Contemporary Finnish Contexts funded by the Academy of Finland. It opens up a vital perspective on the multiplicity and variety of the experience of suffering and that it is particularly through the use of the ethnographic method that these experiences can be brought to light. Keywords: suffering, uncertainty, phenomenology, habitus, agency, cancer, farming

Personporträttet som tidningsgenre : En närläsningsstudie med fokus på innehållsliga teman, berättarkonventioner och kön

The thesis The portrait interview as a newspaper genre. A qualitative close reading focussing on topical motifs, conventions of narration, and gender defines the portrait interview as a newspaper genre and analyses how the personalities in the portraits are constructed textually. The main body of material consists of 107 portrait interviews in two morning newspapers, Dagens Nyheter (published in Stockholm, Sweden) and Hufvudstadsbladet (published in Swedish in Helsinki, Finland), during two one-week periods (week 46/1999 and week 38/2002). There is also complementary material of 59 portraits from four magazines. The study is carried out within the research traditions of journalistic genre studies, gender and journalism, and critical text analysis. It is comprised of a qualitative close reading focussing on content (topical motifs or themes), conventions of narration, and gender. The methods used to carry out the study are qualitative close reading and quantitative content analysis. The analysis identifies the stylistic elements that differentiate the portrait genre from other journalistic genres, as well as from the autobiographical genre, and explores what opportunities and limitations these elements present for the inclusion of even more women protagonists in the portrait genre. The portrait interview is an exception from the critical mission of journalism in general, with its position as a genre of politeness. Since a typical characteristic of the portrait interview genre is that it pays tribute to the protagonist, the genre reveals the kind of personalities and lives that are seen as admirable in society. Four levels of portrait interview are defined: the prototype portrait, the pure portrait, the hybrid portrait and the marginal portrait. The prototype is a raw version of a portrait that fulfils the criteria but may be lacking in content and stylistics. The pure portrait does not lack these qualities and resembles an ideal portrait. The hybrid is a borderline case which relates to another genre or is a mixture between the portrait and some other genre, most commonly the news genre. The marginal portrait does not fulfil the criteria, and can therefore be seen as an inadequate portrait. For example, obituaries and caricatures are excluded if the protagonist s voice is never quoted. The analysis resulted in three factors that in part help to explain why the portrait interview genre has somewhat more female protagonists than journalistic news texts do in general. The four main reasons why women are presented somewhat more in the portrait genre than in other journalistic genres are: (i) women are shown as exceptions to the female norm when, for example, taking a typical male job or managing in positions where there are few women; (ii) women are shown as representing female themes ; (iii) use of the double bind as a story-generating factor; and (iv) the intimisation of journalism. The double bind usually builds up the narration on female ambiguity in the contradiction between private and public life, for example family and career, personal desire and work. The intimisation of journalism and the double bind give women protagonists somewhat more publicity also because of the tendency of portrait interviews to create conflicts within the protagonist, as an exception to journalism in general where conflicts are created or seen as existing between, for example, persons, groupings or parties. Women protagonists and their lives create an optimal narration of inner conflicts originating in the double bind as men are usually not seen as suffering from these conflicts. The analysis also resulted in gendered portrait norms: The feminine portrait norm and the masculine portrait norm or more concretely, professional life and family life as expectation and exception. Women are expected to be responsible parents and mediocre professionals, while men are expected to be professionals and in their free time engaging fathers. Key words: journalism, genre, portrait interview, gender, interview, newspaper, women s magazine.

Cystatin C, a measure of renal function, as prognostic risk marker in acute heart failure : Studies on the cardiorenal syndrome

Acute heart failure (AHF) is a complex syndrome associated with exceptionally high mortality. Still, characteristics and prognostic factors of contemporary AHF patients have been inadequately studied. Kidney function has emerged as a very powerful prognostic risk factor in cardiovascular disease. This is believed to be the consequence of an interaction between the heart and kidneys, also termed the cardiorenal syndrome, the mechanisms of which are not fully understood. Renal insufficiency is common in heart failure and of particular interest for predicting outcome in AHF. Cystatin C (CysC) is a marker of glomerular filtration rate with properties making it a prospective alternative to the currently used measure creatinine for assessment of renal function. The aim of this thesis is to characterize a representative cohort of patients hospitalized for AHF and to identify risk factors for poor outcome in AHF. In particular, the role of CysC as a marker of renal function is evaluated, including examination of the value of CysC as a predictor of mortality in AHF. The FINN-AKVA (Finnish Acute Heart Failure) study is a national prospective multicenter study conducted to investigate the clinical presentation, aetiology and treatment of, as well as concomitant diseases and outcome in, AHF. Patients hospitalized for AHF were enrolled in the FINN-AKVA study, and mortality was followed for 12 months. The mean age of patients with AHF is 75 years and they frequently have both cardiovascular and non-cardiovascular co-morbidities. The mortality after hospitalization for AHF is high, rising to 27% by 12 months. The present study shows that renal dysfunction is very common in AHF. CysC detects impaired renal function in forty percent of patients. Renal function, measured by CysC, is one of the strongest predictors of mortality independently of other prognostic risk markers, such as age, gender, co-morbidities and systolic blood pressure on admission. Moreover, in patients with normal creatinine values, elevated CysC is associated with a marked increase in mortality. Acute kidney injury, defined as an increase in CysC within 48 hours of hospital admission, occurs in a significant proportion of patients and is associated with increased short- and mid-term mortality. The results suggest that CysC can be used for risk stratification in AHF. Markers of inflammation are elevated both in heart failure and in chronic kidney disease, and inflammation is one of the mechanisms thought to mediate heart-kidney interactions in the cardiorenal syndrome. Inflammatory cytokines such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) correlate very differently to markers of cardiac stress and renal function. In particular, TNF-α showed a robust correlation to CysC, but was not associated with levels of NT-proBNP, a marker of hemodynamic cardiac stress. Compared to CysC, the inflammatory markers were not strongly related to mortality in AHF. In conclusion, patients with AHF are elderly with multiple co-morbidities, and renal dysfunction is very common. CysC demonstrates good diagnostic properties both in identifying impaired renal function and acute kidney injury in patients with AHF. CysC, as a measure of renal function, is also a powerful prognostic marker in AHF. CysC shows promise as a marker for assessment of kidney function and risk stratification in patients hospitalized for AHF.

Zur lexikographischen Darstellung der Adjektivsyntax in neueren einsprachigen Wörtbüchern des Deutschen

The main objects of the investigation were the syntactic functions of adjectives. The reason for the interest in these functions are the different modes of use, in which an adjective can occur. All together an adjective can take three different modes of use: attributive (e. g. a fast car), predicative (e. g. the car is fast) and adverbial (e. g. the car drives fast). Since an adjective cannot always take every function, some dictionaries (esp. learner s dictionaries) deliver information within the lexical entry about any restrictions. The purpose of the research consisted of a comparison in relation to the lexical entries of adjectives, which were investigated within four selected monolingual German-speaking dictionaries. The comparison of the syntactical data of adjectives were done to work out the differences and the common characteristics of the lexical entries concerning the different modes of use and to analyse respective to assess them. In the foreground, however, were the differences of the syntactical information. Concerning those differences it had to be worked out, which entry is the grammatically right one respective if one entry is in fact wrong. To find that out an empirical analysis was needed, which based on the question in which way an adjective is used within a context as far as there are no conforming data within the dictionaries. The delivery of the correctness and the homogeneity of lexical entries of German-speaking dictionaries are very important to support people who are learning the German language and to ensure the user friendliness of dictionaries. Throughout the investigations it became clear that in almost half of the cases (over 40 %) syntactical information of adjectives differ from each other within the dictionaries. These differences make it for non-native speakers of course very difficult to understand the correct usage of an adjective. Thus the main aim of the doctoral thesis was it to deliver and to demonstrate the clear syntactical usage of a certain amount of adjectives.

Vidare klarläggs de effekter som kan uppkomma för såväl kunden själv som tjänsteorganisationen och andra inblandade kunder. Olika typer av effekter lyfts fram och tydliggörs med koppling till bland annat tidsrelaterade inslag. Kunders inflytande på såväl kvalitetsupplevelser som produktivitet är härvid av naturligt intresse. Teoretisk analys och begreppsutveckling har varit tongivande inslag i forskningsstrategin, samtidigt som perspektivfrågan har intagit en avgörande position. Vidare har erfarenhetsbaserade bilder av ”kundens vardag” byggt en väsentlig grund, parallellt med teoretiska erfarenheter. I arbetet utvecklas och presenteras referensramar för kunders medverkan i tjänsteprocessen. Inom ramen för en samlad bild erbjuds härigenom möjligheter till analys av konsumentrelaterade verksamheter av skiftande karaktär. Detta framstår som väsentligt med hänsyn till de variationer som kan framträda inom tjänstesektorn.

Lojalitet i licensavtal

Loyalty in Licensing Agreements The purpose of the dissertation is to analyse the impact of the principle of loyalty on licensing agreements from the viewpoint of Finnish law using the traditional legal method (Rechtsdogmatik) combined with empirical data in the form of licensing agreements. The need for good licensing agreements is crucial. One should avoid mechanical and stereotyped agreements in favour of more conscious and goal-oriented ones. When the parties' will and goals have been made clear, the drafting technique should be chosen accordingly. The importance of the principle of loyalty in the interpretation of licensing agreements varies according to their degree of relationality. This is a concept originating in the relational contract theory, more precisely Ian Macneil's spectrum of contracts, where contracts can be placed on an axis according to their degree of relationality. In the dissertation different factors are used to conclude whether the licensing agreement at hand is to be placed on the axis closer to the transactional pole or closer to the relational pole. A conclusion of the dissertation is that few licensing agreements can be placed so close to the transactional pole, that the principle of loyalty lacks importance altogether. The impact of the principle of loyalty the main focus of which is on fostering the contracting parties to behave in accordance with best practices, not for example on altering contract terms is analysed in different situations where the parties' interests typically collide. These situations are discussed from the point of view of three patent and knowhow licensing agreements that differ as to their degree of relationality. A balance needs to be struck between freedom of contract and relational needs. Especially when interpreting more modern licensing agreements, one should not focus on the written document alone, as is often recommended in the literature on Nordic intellectual property law. Neither is the principle of caveat emptor a proper starting point. Moreover, where the parties are of equal bargaining power, one should not assume that the grants in licensing agreements are to be interpreted narrowly. Focus in the interpretation should instead be on the entirety of the circumstances.

Juverhälsoproblem orsakade av Streptococcus agalactiae på stora mjölkgårdar med mjölkningsrobot

Streptococcus agalactiae –juverinflammation var tidigare ett stort problem i många länder, inklusive Finland. I och med förbättrad mjölkningshygien och antibiotikabehandlingar har bakterien så gott som eradikerats från mjölkbesättningarna. Nu verkar bakterien i viss mån ha kommit tillbaka till våra stora mjölkgårdar. Avhandlingens experimentella del utfördes på en mjölkgård, med ca 180 mjölkande och tre mjölkningsrobotar, som haft problem med Str. agalactiae. Man hoppades utreda hur stort problemet på gården var samt möjliga smittovägar. Man undersökte också möjligheten att använda mjölkningsrobotens automatiska provtagningsutrustning för provtagning av bakteriella prov. PCRmetoden jämfördes med konventionell odling vid diagnostik av juverinflammationer orsakade av Str. agalactiae. På gården gick man igenom anteckningar samt hälso- och seminkort för att få en bild över situationen. Man gjorde en uppföljning av mjölkningen för tolv kor vid den ena mjölkningsroboten. Man tog 47 stycken kospecifika mjölkprov samt ett prov från mjölktanken. Mjölkprov i tre serier både mjölkade för hand och direkt från mjölkuppsamlaren på mjölkningsroboten togs. Man tog sammanlagt 23 renlighetsprov från mjölkningsroboten, tre från den automatiska provtagningsutrustningen samt två från djurskötarnas händer. Från den automatiska provtagningsutrustningen togs även ett genomsköljningsprov. Av mjölkprov som tidigare tagits på gården hade man hittat Str. agalactiae i ca 17%. I denna studie hittades Str. agalactiae i tre kospecifika mjölkprov, vilket motsvarar en prevalens på ca 2%. Vid uppföljningen av mjölkningarna upptäcktes inget alarmerande, men spenarnas hälsa samt tommjölkningar är något som bör följas upp. Av renlighetsproven hittades Str. agalactiae i ett prov taget från borsthållaren. Svaren från mjölkproven tagna i serier tyder på att den automatiska provtagningsutrustningen inte går att använda till bakteriella prov, eftersom mjölken från en Str. agalactiae –infekterad ko verkar påverka resultatet också hos följande kor. Resultatet är väntat, eftersom mjölkprov alltid skall tas aseptiskt och det går inte med den automatiska provtagningsutrustningen så som den i dagsläget är utvecklad. Från sju av nio mjölkprov, där man hittat Str. agalactiae med PCR-metoden, hittades bakterien också med konventionell odling. Från tankmjölksprovet kunde man inte hitta Str. agalactiae med konventionell odling. PCR-metoden verkar enligt den här studien vara mer känslig att upptäcka Str. agalactiae jämfört med konventionell odling.
