Puumala virus (PUUV) is the causative agent of nephropathia epidemica (NE), a mild form of hemorrhagic fever with renal syndrome. Finland has the highest documented incidence of NE with around 1000 cases diagnosed annually. PUUV is also found in other Scandinavian countries, Central Europe and the European part of Russia. PUUV belongs to the genus Hantavirus in the family Bunyaviridae. Hantaviruses are rodent-borne viruses each carried by a specific host that is persistently and asymptomatically infected by the virus. PUUV is carried by the bank voles (Myodes glareolus, previously known as Clethrionomys glareolus). Hantaviruses have co-evolved with their carrier rodents for millions of years and these host animals are the evolutionary scene of hantaviruses. In this study, PUUV sequences were recovered from bank voles captured in Denmark and Russian Karelia to study the evolution of PUUV in Scandinavia. Phylogenetic analysis of these strains showed a geographical clustering of genetic variants following the presumable migration pattern of bank voles during the recolonization of Scandinavia after the last ice age approximately 10 000 years ago. The currently known PUUV genome sequences were subjected to in-depth phylogenetic analyses and the results showed that genetic drift seems to be the major mechanism of PUUV evolution. In general, PUUV seems to evolve quite slowly following a molecular clock. We also found evidence for recombination in the evolution of some genetic lineages of PUUV. Viral microevolution was studied in controlled virus transmission in colonized bank voles and changes in quasispecies dynamics were recorded as the virus was transmitted from one animal to another. We witnessed PUUV evolution in vivo, as one synonymous mutation became repeatedly fixed in the viral genome during the experiment. The detailed knowledge on the PUUV diversity was used to establish new sensitive and specific detection methods for this virus. Direct viral invasion of the hypophysis was demonstrated for the first time in a lethal case of NE. PUUV detection was done by immunohistochemistry, in situ hybridization and RT-nested-PCR of the autopsy tissue samples.

From bark bread to pizza - Food and exceptional circumstances: reactions of Finnish society to crises of food supply This study on the food supply under exceptional circumstances lies within the nutritional, historical and social sciences. The perspective and questions come under nutrition science, but are part of social decision-making. The study focuses on the first and second world wars as well as on contemporary society at the beginning of the 21st century. The main purpose of this study is to explore how Finnish society has responded to crises and what measures it has taken to sustain institutional food services and the food supply of households. The particular study interests include the school catering and food services in hospitals during the world wars. The situation in households is reflected in the counseling work carried out by state-run or civic organisations. Interest also focuses on the action of the scientific community. The decisions made in Finland are projected onto the solutions developed in some other European countries. The study is based primarily on the archive documents and annual reports prepared by food and health care authorities. Major source materials include scientific and professional publications. The evaluation of the situation in contemporary Finnish society is based on corresponding emergency plans and guidelines. The written material is supplemented by discussions with experts. Food rationing during the WWI and WWII differed in extent, details and unity. The food intake of some population groups was occasionally inadequate both in quantity, quality and safety. The counseling of the public focused on promoting self-sufficiency, improving cooking skills and widening food habits. One of the most vulnerable groups in regard to nutrition was long-term patients in institutions. As for future development, the world wars were never-theless important periods for public food services and counseling practices. WWII was also an important period for product development in the food industry. Significant work on food substitutes was carried out by Professor Carl Tigerstedt during WWI. The research of Professors A. I. Virtanen and Paavo Simola during WWII focused on vitamins. Crises threatening societies now differ from those faced a hundred years ago. Finland is bet-ter prepared, but in many ways more vulnerable to and dependent on other actors. Food rationing is a severe means of handling the scarcity of food, which is why contemporary society relies primarily on preparedness planning. Civic organisations played a key role during the world wars, and establishing an emergency food supply remains on their agenda. Although the objective of protecting the population remains the same for nutrition, food production, and food consumption, threat scenarios and the knowledge and skill levels of citizens are constantly changing. Continuous monitoring and evaluation is therefore needed.

For the first time the attempt of Denmark, Finland, Norway and Sweden to increase Nordic economic co-operation and integration (NORDEK 1968-1970) is analysed by using records from the four governments archives and interviews with central actors participating. A dominating argument has until now been that dynamics in Nordic economic integration is different from dynamics in European integration. This archive based study disproves the myth however of ideological Nordism and of short term political developments outside Norden as most important for the NORDEK initiative. The NORDEK initiative was actually more a consequence of a long term socioeconomic and socio-political path dependant process. The study also disproves the myth that the NORDEK plan was a political and ideological symbol without socioeconomic substance. The purpose with NORDEK was to create a better basis for generating economic growth and social welfare. The proposed NORDEK institutions were therefore developed to promote economic progress. The study finally shows that the NORDEK failure in 1970 was not a result of lacking economic rationale or incompatible economic interests. The failure was a result of a power struggle in Finnish domestic policy and lacking political will in the other Nordic countries to continue without Finland.

Proteolysis is important in bacterial pathogenesis and colonization of animal and plant hosts. In this work I have investigated the functions of the bacterial outer membrane proteases, omptins, of Yersinia pestis and Salmonella enterica. Y. pestis is a zoonotic pathogen that causes plague and has evolved from gastroenteritis-causing Yersinia pseudotuberculosis about 13 000 years ago. S. enterica causes gastroenteritis and typhoid fever in humans. Omptins are transmembrane β-barrels with ten antiparallel β-strands and five surface-exposed loops. The loops are important in substrate recognition, and variation in the loop sequences leads to different substrate selectivities between omptins, which makes omptins an ideal platform to investigate functional adaptation and to alter their polypeptide substrate preferences. The omptins Pla of Y. pestis and PgtE of S. enterica are 75% identical in their amino acid sequences. Pla is a multifunctional protein with proteolytic and non-proteolytic functions, and it increases bacterial penetration and proliferation in the host. Functions of PgtE increase migration of S. enterica in vivo and bacterial survival in mouse macrophages, thus enhancing bacterial spread within the host. Mammalian plasminogen/fibrinolytic system maintains the balance between coagulation and fibrinolysis and participates in several cellular processes, e.g., cell migration and degradation of extracellular matrix proteins. This system consists of activation cascades, which are strictly controlled by several regulators, such as plasminogen activator inhibitor 1 (PAI-1), α2-antiplasmin (α2AP), and thrombin-activatable fibrinolysis inhibitor (TAFI). This work reveals novel interactions of the omptins of Y. pestis and S. enterica with the regulators of the plasminogen/fibrinolytic system: Pla and PgtE inactivate PAI-1 by cleavage at the reactive site peptide bond, and degrade TAFI, preventing its activation to TAFIa. Structure-function relationship studies with Pla showed that threonine 259 of Pla is crucial in plasminogen activation, as it prevents degradation of the plasmin catalytic domain by the omptin and thus maintains plasmin stability. In this work I constructed chimeric proteins between Pla and Epo of Erwinia pyrifoliae that share 78% sequence identity to find out which amino acids and regions in Pla are important for its functions. Epo is neither a plasminogen activator nor an invasin, but it degrades α2AP and PAI-1. Cumulative substitutions towards Pla sequence turned Epo into a Pla-like protein. In addition to threonine 259, loops 3 and 5 are critical in plasminogen activation by Pla. Turning Epo into an invasin required substitution of 31 residues located at the extracellular side of the Epo protein above the lipid bilayer, and also of the β1-strand in the N-terminal transmembrane region of the protein. These studies give an example of how omptins adapt to novel functions that advantage their host bacteria in different ecological niches.

The occurrence and nature of civilian firearm- and explosion-injuries in Finland, and the nature of severe gunshot injuries of the extremities were described in seven original articles. The main data sources used were the National Hospital Discharge Register, the Cause-of-Death Register, and the Archive of Death Certificates at Statistics Finland. The present study was population based. Epidemiologic methods were used in six and clinical analyses in five papers. In these clinical studies, every original hospital record and death certificate was critically analyzed. The trend of hospitalized firearm injuries has slightly declined in Finland from the late 1980s to the early 2000s. The occurrence decreased from 5.1 per 100 000 person-years in 1990 to 2.6 in 2003. The decline was found in the unintentional firearm injuries. A high incidence of unintentional injuries by firearms was characteristic of the country, while violence and homicides by firearms represented a minor problem. The incidence of fatal non-suicidal firearm injuries has been stable, 1.8 cases per 100 000 person-years. Suicides using firearms were eight times more common during the period studied. This is contrary to corresponding reports from many other countries. However, the use of alcohol and illegal drugs or substances was detected in as many as one-third of the injuries studied. The median length of hospitalization was three days and it was significantly associated (p<0.001) with the type of injury. The mean length of hospital stay has decreased from the 1980s to the early 2000s. In this study, there was a special interest in gunshot injuries of the extremities. From a clinical point of view, the nature of severe extremital gunshot wounds, as well as the primary operative approach in their management, varied. The patients with severe injuries of this kind were managed at university and central hospital emergency departments, by general surgeons in smaller hospitals and by cardiothoracic or vascular surgeons in larger hospitals. Injuries were rarities and as such challenges for surgeons on call. Some noteworthy aspects of the management were noticed and these should be focused on in the future. On the other hand, the small population density and the relatively large geographic area of Finland do not favor high volume, centralized trauma management systems. However, experimental war surgery has been increasingly taught in the country from the 1990s, and excellent results could be expected during the present decade. Epidemiologically, explosion injuries can be considered a minor problem in Finland at present, but their significance should not be underestimated. Fatal explosion injuries showed up sporadically. An increase occurred from 2002 to 2004 for no obvius reason. However, in view of the historical facts, a possibility for another rare major explosion involving several people might become likely within the next decade. The national control system of firearms is mainly based on the new legislations from 1998 and 2002. However, as shown in this study, there is no reason to assume that the national hospitalization policies, or the political climate, or the legislation might have changed over the study period and influenced the declining development, at least not directly. Indeed, the reason for the decline to appear in the incidence of unintentional injuries only remains unclear. It may derive from many practical steps, e.g. locked firearm cases, or from the stability of the community itself. For effective reduction of firearm-related injuries, preventive measures, such as education and counseling, should be targeted at recreational firearm users. To sum up, this study showed that the often reported increasing trend in firearm as well as explosion-related injuries has not manifested in Finland. Consequently, it can be recognized that, overall, the Finnish legislation together with the various strategies have succeeded in preventing firearm- and explosion-related injuries in the country.

The systemic autoinflammatory disorders are a group of rare diseases characterized by periodically recurring episodes of acute inflammation and a rise in serum acute phase proteins, but with no signs of autoimmunity. At present eight hereditary syndromes are categorized as autoinflammatory, although the definition has also occasionally been extended to other inflammatory disorders, such as Crohn s disease. One of the autoinflammatory disorders is the autosomally dominantly inherited tumour necrosis factor receptor-associated periodic syndrome (TRAPS), which is caused by mutations in the gene encoding the tumour necrosis factor type 1 receptor (TNFRSF1A). In patients of Nordic descent, cases of TRAPS and of three other hereditary fevers, hyperimmunoglobulinemia D with periodic fever syndrome (HIDS), chronic infantile neurologic, cutaneous and articular syndrome (CINCA) and familial cold autoinflammatory syndrome (FCAS), have been reported, TRAPS being the most common of the four. Clinical characteristics of TRAPS are recurrent attacks of high spiking fever, associated with inflammation of serosal membranes and joints, myalgia, migratory rash and conjunctivitis or periorbital cellulitis. Systemic AA amyloidosis may occur as a sequel of the systemic inflammation. The aim of this study was to investigate the genetic background of hereditary periodically occurring fever syndromes in Finnish patients, to explore the reliability of determining serum concentrations of soluble TNFRSF1A and metalloproteinase-induced TNFRSF1A shedding as helpful tools in differential diagnostics, as well as to study intracellular NF-κB signalling in an attempt to widen the knowledge of the pathomechanisms underlying TRAPS. Genomic sequencing revealed two novel TNFRSF1A mutations, F112I and C73R, in two Finnish families. F112I was the first TNFRSF1A mutation to be reported in the third extracellular cysteine-rich domain of the gene and C73R was the third novel mutation to be reported in a Finnish family, with only one other TNFRSF1A mutation having been reported in the Nordic countries. We also presented a differential diagnostic problem in a TRAPS patient, emphasizing for the clinician the importance of differential diagnostic vigiliance in dealing with rare hereditary disorders. The underlying genetic disease of the patient both served as a misleading factor, which possibly postponed arrival at the correct diagnosis, but may also have predisposed to the pathologic condition, which led to a critical state of the patient. Using a method of flow cytometric analysis modified for the use on fresh whole blood, we studied intracellular signalling pathways in three Finnish TRAPS families with the F112I, C73R and the previously reported C88Y mutations. Evaluation of TNF-induced phosphorylation of NF-κB and p38, revealed low phosphorylation profiles in nine out of ten TRAPS patients in comparison to healthy control subjects. This study shows that TRAPS is a diagnostic possibility in patients of Nordic descent, with symptoms of periodically recurring fever and inflammation of the serosa and joints. In particular in the case of a family history of febrile episodes, the possibility of TRAPS should be considered, if an etiology of autoimmune or infectious nature is excluded. The discovery of three different mutations in a population as small as the Finnish, reinforces the notion that the extracellular domain of TNFRSF1A is prone to be mutated at the entire stretch of its cysteine-rich domains and not only at a limited number of sites, suggesting the absence of a founder effect in TRAPS. This study also demonstrates the challenges of clinical work in differentiating the symptoms of rare genetic disorders from those of other pathologic conditions and presents the possibility of an autoinflammatory disorder as being the underlying cause of severe clinical complications. Furthermore, functional studies of fresh blood leukocytes show that TRAPS is often associated with a low NF-κB and p38 phosphorylation profile, although low phosphorylation levels are not a requirement for the development of TRAPS. The aberrant signalling would suggest that the hyperinflammatory phenotype of TRAPS is the result of compensatory NF-κB-mediated regulatory mechanisms triggered by a deficiency of the innate immune response.

Crohn s disease (CD) and ulcerative colitis (UC), collectively known as inflammatory bowel disease (IBD), are characterised by chronic inflammation of the gastrointestinal tract. IBD prevalence in Finland is approximately 3-4 per 1000 inhabitants with a peak incidence in adolescence. The symptoms of IBD include diarrhoea, abdominal pain, fever, and weight loss. The precise aetiology of IBD is unknown but interplay of environmental risk factors and immunologic changes trigger the disease in a genetically susceptible individual. Twin and family studies have provided strong evidence for genetic factors in IBD susceptibility, and genetic factors may be more prominent in CD than UC. The first CD susceptibility gene was identified in 2001. Three common mutations R702W, G908R, and 1007fs of the CARD15/NOD2 gene are shown to associate independently with CD but the magnitude of association varies between different populations. The present study aimed at identifying mutations and genetic variations in IBD susceptibility and candidate genes. In addition, correlation to phenotype was also assessed. One of the main objectives of this study was to evaluate the role of CARD15 in a Finnish CD cohort. 271 CD patients were studied for the three common mutations and the results showed a lower mutation frequency than in other Caucasian populations. Only 16% of the patients carried one of the three mutations. Ileal location as well as stricturing and penetrating behaviour of the disease were associated with occurrence of the mutations. The whole protein coding region of CARD15 was screened for possible Finnish founder mutations. In addition to several sequence variants, five novel mutations (R38M, W355X, P727L, W907R, and R1019X) were identified in five patients. Functional consequences of these novel variants were studied in vitro, and these studies demonstrated a profound impairment of MDP response. Investigation of CARD15 mutation frequency in healthy people across three continents showed a large geographic fluctuation. No simple correlation between mutation frequency and disease incidence was seen in populations studied. The occurrence of double mutant carriers in healthy controls suggested that the penetrance of risk alleles is low. Other main objectives aimed at identifying other genetic variations that are involved in the susceptibility to IBD. We investigated the most plausible IBD candidate genes including TRAF6, SLC22A4, SLC22A5, DLG5, TLR4, TNFRSF1A, ABCB1/MDR1, IL23R, and ATG16L1. The marker for a chromosome 5 risk haplotype and the rare HLA-DRB1*0103 allele were also studied. The study cohort consisted of 699 IBD patients (240 CD and 459 UC), of which 23% had a first-degree relative with IBD. Of the several candidate genes studied, IL23R was associated with CD susceptibility, and TNFRSF1A as well as the HLA-DRB1*0103 allele with UC susceptibility. IL23R variants also showed association with the stricturing phenotype and longer disease duration in CD patients. In addition, TNFRSF1A variants were more common among familial UC and ileocolonic CD. In conclusion, the common CARD15 mutations were shown to account for 16% of CD cases in Finland. Novel CARD15 variants identified in the present study are most likely disease-causing mutations, as judged by the results of in vitro studies. The present study also confirms the IL23R association with CD susceptibility and, in addition, TNFRSF1A and HLA-DRB1*0103 allele association with UC of specific clinical phenotypes.

Hantaviruses, members of the genus Hantavirus in the Bunyaviridae family, are enveloped single-stranded RNA viruses with tri-segmented genome of negative polarity. In humans, hantaviruses cause two diseases, hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS), which vary in severity depending on the causative agent. Each hantavirus is carried by a specific rodent host and is transmitted to humans through excreta of infected rodents. The genome of hantaviruses encodes four structural proteins: the nucleocapsid protein (N), the glycoproteins (Gn and Gc), and the polymerase (L) and also the nonstructural protein (NSs). This thesis deals with the functional characterization of hantavirus N protein with regard to its structure. Structural studies of the N protein have progressed slowly and the crystal structure of the whole protein is still not available, therefore biochemical assays coupled with bioinformatical modeling proved essential for studying N protein structure and functions. Presumably, during RNA encapsidation, the N protein first forms intermediate trimers and then oligomers. First, we investigated the role of N-terminal domain in the N protein oligomerization. The results suggested that the N-terminal region of the N protein forms a coiled-coil, in which two antiparallel alpha helices interact via their hydrophobic seams. Hydrophobic residues L4, I11, L18, L25 and V32 in the first helix and L44, V51, L58 and L65 in the second helix were crucial for stabilizing the structure. The results were consistent with the head-to-head, tail-to-tail model for hantavirus N protein trimerization. We demonstrated that an intact coiled-coil structure of the N terminus is crucial for the oligomerization capacity of the N protein. We also added new details to the head-to-head, tail-to-tail model of trimerization by suggesting that the initial step is based on interaction(s) between intact intra-molecular coiled-coils of the monomers. We further analyzed the importance of charged aa residues located within the coiled-coil for the N protein oligomerization. To predict the interacting surfaces of the monomers we used an upgraded in silico model of the coiled-coil domain that was docked into a trimer. Next the predicted target residues were mutated. The results obtained using the mammalian two-hybrid assay suggested that conserved charged aa residues within the coiled-coil make a substantial contribution to the N protein oligomerization. This contribution probably involves the formation of interacting surfaces of the N monomers and also stabilization of the coiled-coil via intramolecular ionic bridging. We proposed that the tips of the coiled-coils are the first to come into direct contact and thus initiate tight packing of the three monomers into a compact structure. This was in agreement with the previous results showing that an increase in ionic strength abolished the interaction between N protein molecules. We also showed that residues having the strongest effect on the N protein oligomerization are not scattered randomly throughout the coiled-coil 3D model structure, but form clusters. Next we found evidence for the hantaviral N protein interaction with the cytoplasmic tail of the glycoprotein Gn. In order to study this interaction we used the GST pull-down assay in combination with mutagenesis technique. The results demonstrated that intact, properly folded zinc fingers of the Gn protein cytoplasmic tail as well as the middle domain of the N protein (that includes aa residues 80 248 and supposedly carries the RNA-binding domain) are essential for the interaction. Since hantaviruses do not have a matrix protein that mediates the packaging of the viral RNA in other negatve stranded viruses (NSRV), hantaviral RNPs should be involved in a direct interaction with the intraviral domains of the envelope-embedded glycoproteins. By showing the N-Gn interaction we provided the evidence for one of the crucial steps in the virus replication at which RNPs are directed to the site of the virus assembly. Finally we started analysis of the N protein RNA-binding region, which is supposedly located in the middle domain of the N protein molecule. We developed a model for the initial step of RNA-binding by the hantaviral N protein. We hypothesized that the hantaviral N protein possesses two secondary structure elements that initiate the RNA encapsidation. The results suggest that amino acid residues (172-176) presumably act as a hook to catch vRNA and that the positively charged interaction surface (aa residues 144-160) enhances the initial N-RNA interacation. In conclusion, we elucidated new functions of hantavirus N protein. Using in silico modeling we predicted the domain structure of the protein and using experimental techniques showed that each domain is responsible for executing certain function(s). We showed that intact N terminal coiled-coil domain is crucial for oligomerization and charged residues located on its surface form a interaction surface for the N monomers. The middle domain is essential for interaction with the cytoplasmic tail of the Gn protein and RNA binding.

The evacuation of Finnish children to Sweden during WW II has often been called a small migration . Historical research on this subject is scarce, considering the great number of children involved. The present research has applied, apart from the traditional archive research, the framework of history-culture developed by Rüsen in order to have an all-inclusive approach to the impact of this historical event. The framework has three dimensions: political, aesthetic and cognitive. The collective memory of war children has also been discussed. The research looks for political factors involved in the evacuations during the Winter War and the Continuation War and the post-war period. The approach is wider than a purely humanitarian one. Political factors have had an impact in both Finland and Sweden, beginning from the decision-making process and ending with the discussion of the unexpected consequences of the evacuations in the Finnish Parliament in 1950. The Winter War (30.11.1939 13.3.1940) witnessed the first child transports. These were also the model for future decision making. The transports were begun on the initiative of Swedes Maja Sandler, the wife of the resigned minister of foreign affairs Rickard Sandler, and Hanna Rydh-Munck af Rosenschöld , but this activity was soon accepted by the Swedish government because the humanitarian help in the form of child transports lightened the political burden of Prime Minister Hansson, who was not willing to help Finland militarily. It was help that Finland never asked for and it was rejected at the beginning. The negative response of Minister Juho Koivisto was not taken very seriously. The political forces in Finland supporting child transports were stronger than those rejecting them. The major politicians in support belonged to Finland´s Swedish minority. In addition, close to 1 000 Finnish children remained in Sweden after the Winter War. No analysis was made of the reasons why these children did not return home. A committee set up to help Finland and Norway was established in Sweden in 1941. Its chairman was Torsten Nothin, an influential Swedish politician. In December 1941 he appealed to the Swedish government to provide help to Finnish children under the authority of The International Red Cross. This plea had no results. The delivery of great amounts of food to Finland, which was now at war with Great Britain, had automatically caused reactions among the allies against the Swedish imports through Gothenburg. This included the import of oil, which was essential for the Swedish navy and air force. Oil was later used successfully to force a reduction in commerce between Sweden and Finland. The contradiction between Sweden´s essential political interests and humanitarian help was solved in a way that did not harm the country´s vital political interests. Instead of delivering help to Finland, Finnish children were transported to Sweden through the organisations that had already been created. At the beginning of the Continuation War (25.6.1941 27.4.1945) negative opinion regarding child transports re-emerged in Finland. Karl-August Fagerholm implemented the transports in September 1941. In 1942, members of the conservative parties in the Finnish Parliament expressed their fear of losing the children to the Swedes. They suggested that Finland should withdraw from the inter-Nordic agreement, according to which the adoptions were approved by the court of the country where the child resided. This initiative failed. Paavo Virkkunen, an influential member of the conservative party Kokoomus in Finland, favoured the so-called good-father system, where help was delivered to Finland in the form of money and goods. Virkkunen was concerned about the consequences of a long stay in a Swedish family. The risk of losing the children was clear. The extreme conservative party (IKL, the Patriotic Movement of the Finnish People) wanted to alienate Finland from Sweden and bring Finland closer to Germany. Von Blücher, the German ambassador to Finland, had in his report to Berlin, mentioned the political consequences of the child transports. Among other things, they would bring Finland and Sweden closer to each other. He had also paid attention to the Nordic political orientation in Finland. He did not question or criticize the child transports. His main interest was to increase German political influence in Finland, and the Nordic political orientation was an obstacle. Fagerholm was politically ill-favoured by the Germans, because he had a strong Nordic political disposition and had criticised Germany´s activities in Norway. The criticism of child transports was at the same time criticism of Fagerholm. The official censorship organ of the Finnish government (VTL) denied the criticism of child transports in January 1942. The reasons were political. Statements made by members of the Finnish Parliament were also censored, because it was thought that they would offend the Swedes. In addition, the censorship organ used child transports as a means of active propaganda aimed at improving the relations between the two countries. The Finnish Parliament was informed in 1948 that about 15 000 Finnish children still remained in Sweden. These children would stay there permanently. In 1950 the members of the Agrarian Party in Finland stated that Finland should actively strive to get the children back. The party on the left (SKDL, the Democratic Movement of Finnish People) also focused on the unexpected consequences of the child transports. The Social Democrats, and largely Fagerholm, had been the main force in Finland behind the child transports. Members of the SKDL, controlled by Finland´s Communist Party, stated that the war time authorities were responsible for this war loss. Many of the Finnish parents could not get their children back despite repeated requests. The discussion of the problem became political, for example von Born, a member of the Swedish minority party RKP, related this problem to foreign policy by stating that the request to repatriate the Finnish children would have negative political consequences for the relations between Finland and Sweden. He emphasized expressing feelings of gratitude to the Swedes. After the war a new foreign policy was established by Prime Minister (1944 1946) and later President (1946 1956) Juho Kusti Paasikivi. The main cornerstone of this policy was to establish good relations with the Soviet Union. The other, often forgotten, cornerstone was to simultaneously establish good relations with other Nordic countries, especially Sweden, as a counterbalance. The unexpected results of the child evacuation, a Swedish initiative, had violated the good relations with Sweden. The motives of the Democratic Movement of Finnish People were much the same as those of the Patriotic Movement of Finnish People. Only the ideology was different. The Nordic political orientation was an obstacle to both parties. The position of the Democratic Movement of Finnish People was much better than that of the Patriotic Movement of Finnish People, because now one could clearly see the unexpected results, which included human tragedy for the many families who could not be re-united with their children despite their repeated requests. The Swedes questioned the figure given to the Finnish Parliament regarding the number of children permanently remaining in Sweden. This research agrees with the Swedes. In a calculation based on Swedish population registers, the number of these children is about 7 100. The reliability of this figure is increased by the fact that the child allowance programme began in Sweden in 1948. The prerequisite to have this allowance was that the child be in the Swedish population register. It was not necessary for the child to have Swedish nationality. The Finnish Parliament had false information about the number of Finnish children who remained in Sweden in 1942 and in 1950. There was no parliamentary control in Finland regarding child transports, because the decision was made by one cabinet member and speeches by MPs in the Finnish Parliament were censored, like all criticism regarding child transports to Sweden. In Great Britain parliamentary control worked better throughout the whole war, because the speeches regarding evacuation were not censored. At the beginning of the war certain members of the British Labour Party and the Welsh Nationalists were particularly outspoken about the scheme. Fagerholm does not discuss to any great extent the child transports in his memoirs. He does not evaluate the process and results as a whole. This research provides some possibilities for an evaluation of this sort. The Swedish medical reports give a clear picture of the physical condition of the Finnish children when arriving in Sweden. The transports actually revealed how bad the situation of the poorest children was. According to Titmuss, similar observations were made in Great Britain during the British evacuations. The child transports saved the lives of approximately 2 900 children. Most of these children were removed to Sweden to receive treatment for illnesses, but many among the healthy children were undernourished and some suffered from the effects of tuberculosis. The medical inspection in Finland was not thorough. If you compare the figure of 2 900 children saved and returned with the figure of about 7 100 children who remained permanently in Sweden, you may draw the conclusion that Finland as a country failed to benefit from the child transports, and that the whole operation was a political mistake with far-reaching consequenses. The basic goal of the operation was to save lives and have all the children return to Finland after the war. The difficulties with the repatriation of the children were mainly psychological. The level of child psychology in Finland at that time was low. One may question the report by Professor Martti Kaila regarding the adaptation of children to their families back in Finland. Anna Freud´s warnings concerning the difficulties that arise when child evacuees return are also valid in Finland. Freud viewed the emotional life of children in a way different from Kaila: the physical survival of a small child forces her to create strong emotional ties to the person who is looking after her. This, a characteristic of all small children, occurred with the Finnish children too, and it was something the political decision makers in Finland could not see during and after the war. It is a characteristic of all little children. Yet, such experiences were already evident during the Winter War. The best possible solution had been to limit the child transports only to children in need of medical treatment. Children from large and poor families had been helped by organising meals and by buying food from Denmark with Swedish money. Assisting Finland by all possible means should have been the basic goal of Fagerholm in September 1941, when the offer of child transports came from Sweden. Fagerholm felt gratitude towards the Swedes. The risks became clear to him only in 1943. The war children are today a rather scattered and diffuse group of people. Emotionally, part of these children remained in Sweden after the war. There is no clear collective memory, only individual memories; the collective memory of the war children has partly been shaped later through the activities of the war child associations. The main difference between the children evacuated in Finland (for example from Karelia to safer areas with their families) and the war children, who were sent abroad, is that the war children lack a shared story and experience with their families. They were outsiders . The whole matter is sensitive to many of such mothers and discussing the subject has often been avoided in families. The war-time censorship has continued in families through silence and avoidance and Finnish politicians and Finnish families had to face each other on this issue after the war. The lack of all-inclusive historical research has also prevented the formation of a collective awareness among war children returned to Finland or those remaining permanently abroad.. Knowledge of historical facts will help war-children by providing an opportunity to create an all-inclusive approach to the past. Personal experiences should be regarded as part of a large historical entity shadowed by war and where many political factors were at work in both Finland and Sweden. This means strengthening of the cognitive dimension discussed in Rüsen´s all-inclusive historical approach.

The object of study in this thesis is Finnish skiing culture and Alpine skiing in particular from the point of view of ethnology. The objective is to clarify how, when, why and by what routes Alpine skiing found its way to Finland. What other phenomena did it bring forth? The objective is essentially linked to the diffusion of modern sports culture to Finland. The introduction of Alpine skiing to Finland took place at a time when skiing culture was changing: flat terrain skiing was abandoned in favour of cross-country skiing in the early decades of the 20th century, and new techniques and equipment made skiing a much more versatile sport. The time span of the study starts from the late 19th century and ends in the mid-20th century. The spatial focus is in Finland. People and communities formed through their actions are core elements in the study of sports and physical activity. Organizations tend to raise themselves into influential actors in the field of physical culture even if active individuals work in their background. Original archive documents and publications of sports organizations are central source material for this thesis, complemented by newspapers and sports magazines as well as photographs and films on early Alpine skiing in Finland. Ever since their beginning in the late 19th century skiing races in Finland had mostly taken place on flat terrain or sea ice. Skiing in broken cross-country terrain made its breakthrough in the 1920 s, at a time when modern skiing techniques were introduced in instruction manuals. In the late 1920 s the Finnish Women s Physical Education Association (SNLL) developed unconventional forms of pedagogical skiing instruction. They abandoned traditional Finnish flat terrain skiing and boldly looked for influences abroad, which caused friction between the leaders of the women s sports movement and the (male) leaders of the central skiing organization. SNLL was instrumental in launching winter tourism in Finnish Lapland in 1933. The Finnish Tourism Society, the State Railways and sports organizations worked in close co-operation to instigate a boom in tourism, which culminated in the inauguration of a tourist hotel at Pallastunturi hill in the winter of 1938. Following a Swedish model, fell-skiing was developed as a domestic counterpart to Alpine skiing as practiced in Central Europe. The first Finnish skiing resorts were built at sites of major cross-country skiing races. Inspired by the slope at Bad Grankulla health spa, the first slalom skiing races and fell-skiing, slalom enthusiasts began to look for purpose-built sites to practice turn technique. At first they would train in natural slopes but in the late 1930 s new slopes were cleared for slalom races and recreational skiing. The building of slopes and ski lifts and the emergence of organized slalom racing competitions gradually separated Alpine skiing from the old fell-skiing. After the Second World War fell-skiing was transformed into ski trekking on marked courses. At the same time Alpine skiing also parted ways with cross-country skiing to become a sport of its own. In the 1940 s and 1950 s Finnish Alpine skiing was almost exclusively a competitive sport. The specificity of Alpine skiing was enhanced by rapid development of equipment: the new skis, bindings and shoes could only be used going downhill.

Since the second half of the 20th century, cancer has become a dominant disease in Western countries, endangering people regardless of age, gender, race or social status. Every year almost eight million people die of cancer worldwide. In Finland every fourth person is expected to fall ill with cancer at some stage of his or her life. During the 20th century, along with rapid changes in the medical system, people s awareness of cancer has increased a great deal. This has also influenced the image of cancer in popular discourse over the past decades. However, from the scientific point of view there is still much that is unclear about the disease. This thesis shows that this is a big problem for ordinary people, as, according to culture-bound illness ideology, people need an explanation about the origin of their illness in order to help them cope. The main aim of this thesis is to examine the process of being ill with cancer from the patient s point of view, in order to analyse attitudes and behaviour towards cancer and its significance and culture-bound images. This narrative-based study concentrates on patients voicings , which are important in understanding the cancer experience and when attempting to make it more open within current cultural and societal settings. The Kun sairastuin syöpään ( when I fell ill with cancer ) writing competition organised by Suomen Syöpäpotilaat ry (the Finnish Cancer Patients Association), Suomen Syöpäyhdistys ry (the Finnish Cancer Union), and Suomalaisen Kirjallisuuden Seuran kansanrunousarkisto (the Finnish Literary Society Folklore Archive) was announced on the 1st of May 1994 and lasted until the 30th of September 1994. As a result, a total of 672 cancer narratives, totalling 6384 pages, were received, filled with experiences relating to cancer. Written cancer narratives form a body of empirical data that is suitable for content or textual analysis. In this thesis, content analysis is adopted in order to become familiar with the texts and to preselect the themes and analytical units for further examination. I use multiple perspectives in order to interpret cancer patients ideas and reasoning. The ethnomedical approach unites popular health beliefs that originated in Finnish folk medicine, as well as connecting alternative medicine, which patients make use of, with biomedicine, the dominant form of medicine today. In addition to this, patients narratives, which are composed of various structural segments, are approached from the folklorist s perspective. In this way they can be seen as short pathographies, reconstructions of self-negotiation and individual decision making during the illness process. Above all, cancer patients writing describe their feelings, thoughts and experiences. Factors that appear insignificant to modern medicine, overwhelmed as it is by medical technologies that concentrate on dysfunctional tissue within diseased bodies. Ethnomedical study of cancer patients writings gives access to the human side of cancer discourse, and combines both medical, and popular, knowledge of cancer. In my view, the natural world and glimpses of tradition are bound together with one general aim within cancer narratives: to tackle the illness and mediate its meanings. Furthermore, the narrative approach reveals that participants write with the hope of offering a different interpretation of the cancer experience, and thus of confronting culturally pre-defined images and ideologies.

Background and aims: Low stage and curative surgery are established factors for improved survival in gastric cancer. However, not all low-stage patients have a good prognosis. Cyclooxygenase-2 (COX-2) is known to associate with reduced survival in several cancers, and has been shown to play an important role in gastric carcinogenesis. Since new and better prognostic markers are needed for gastric cancer, we studied the prognostic significance of COX-2 and of markers that associate with COX-2 expression. We also studied markers reflecting proliferation and apoptosis, and evaluated their association with COX-2. Our purpose was to construct an accurate prognostic model by combining tissue markers and clinicopathogical factors. Materials and methods: Of 342 consecutive patients who underwent surgery for gastric cancer at Meilahti Hospital, Helsinki University Central Hospital, 337 were included in this study. Low stages I to II were represented by 141 (42%) patients, and high stages III to IV by 196 (58%). Curative surgery was performed on 176 (52%) patients. Survival data were obtained from the national registers. Slides from archive tissue blocks were prepared for immunohistochemistry by use of COX-2, human antigen R (HuR), cyclin A, matrix metalloproteinases 2 and 9 (MMP-2, MMP-9), and Ki-67 antibodies. Immunostainings were scored by microscopy, and scores were entered into a database. Associations of tumor markers with clinicopathological factors were calculated, as well as associations with p53, p21, and results of flow cytometry from earlier studies. Survival analysis was performed by the Kaplan-Meier method, and Cox multivariate models were reconstructed. Cell culture experiments were performed to explore the effect of small interfering (si)RNA of HuR on COX-2 expression in a TMK-1 gastric cancer cell line. Results: Overall 5-year survival was 35.1%. Study I showed that COX-2 was an independent prognostic factor, and that the prognostic impact of COX-2 was more pronounced in low-stage patients. Cytoplasmic HuR expression also associated with reduced survival in gastric cancer patients in a non-independent manner. Cell culture experiments showed that HuR can regulate COX-2 expression in TMK-1 cells in vitro, with an association also between COX-2 and HuR tissue expression in a clinical material. In Study II, cyclin A was an independent prognostic factor and was associated with HuR expression in the gastric cancer material. The results of Study III showed that epithelial MMP-2 associated with survival in univariate, but not in multivariate analysis. However, MMP-9 showed no prognostic value. MMP-2 expression was associated with COX-2 expression. In Study IV, the prognostic power of COX-2 was compared with that of all tested markers associated with survival in Studies I to III, as well as with p21, p53, and flow cytometry results. COX-2 and p53 were independent prognostic factors, and COX-2 expression was associated with that of p53 and Ki-67 and also with aneuploidy. Conclusions: COX-2 is an independent prognostic factor in gastric cancer, and its prognostic power emerges especially in low stage cancer. COX-2 is regulated by HuR, and is associated with factors reflecting invasion, proliferation, and apoptosis. In an extended multivariate model, COX-2 retained its position as an independent prognosticator. COX-2 can be considered a promising new prognostic marker in gastric cancer.

Tämän Pro gradu -tutkielman tarkoituksena on selventää Kansallisen Kokoomuspuolueen kommunisminvastaisuutta 1920-luvulla, tarkemmin ottaen vuoden 1929 eduskuntavaalikamppailussa. Tutkimuskysymykseni liittyvät puolueen identiteetin ja kommunisminvastaisuuden yhteyteen: miten kokoomuspuolueen suhtautuminen kommunismiin kytkeytyi, yhtäältä, oman porvarillisen poliittis-kansallisen identiteetin puolustamiseen, ja toisaalta, vuonna 1929 vallitseviin poliittisiin oloihin, jolloin muun muassa parlamentaarinen järjestelmä herätti laajaa epäluottamusta, kokoomus ajautui sisäiseen kriisiin ja kommunistien kumoustavoite korostui suomalaisessa julkisuudessa? Etsimällä vastauksia näihin kysymyksiin pyrin selittämään mistä osakokonaisuuksista antikommunismi koostui, miten uhkaa muokattiin ja perusteltiin. Mielestäni tärkeää ja mielenkiintoista on miettiä, kuinka kommunisminvastaisuus ilmeni ikään kuin vastauksena muihin yhteiskunnallis-poliittisiin ongelmiin ja turhautumiin. Tutkimukseni teoreettinen viitekehys perustuu toiseuden ja viholliskuvien tutkimukseen, koska toiseuden merkitys identiteetin kehittymiselle on kiistaton. Tähän liittyvän kirjallisuuden lisäksi olen käyttänyt lähteinäni tutkimuskirjallisuutta, sanomalehtiä ja julkaisemattomia arkistolähteitä. Tutkimukseni aatehistoriallisen luonteen vuoksi ensisijainen alkuperäislähteeni on julkaistu materiaali – vaalijulkaisut ja kokoomuslehdistö – jonka avulla olen pyrkinyt analysoimaan puolueen suhtautumista kommunismiin ja sen vaikutusta puolueen identiteetille. Metodini on historiallis-kvalitatiivinen, joka tarkoittaa sitä, että pyrin samaan aikaan huomioimaan sekä puolueen julkisuuskuvan että sen toiminnan kulisseissa. Tämä edellyttää huomion kohdistamista sekä julkaistuun että julkaisemattomaan lähdeaineistoon. Julkaistuun materiaaliin kohdistuneen analyysin pohjalta on mahdollista päätellä, että kokoomus halusi luoda itsestään kuvan jyrkästi kommunisminvastaisena puolueena. Toiseus-analyysin perusteella voidaan sanoa, että kommunismi oli puolueen selvä toinen. Julkisuuskuva ei kuitenkaan välttämättä vastannut puolueen todellisia käsityksiä kommunismista ja sen pohjalle muodostetusta viholliskuvasta. Antikommunismi ja viholliskuvan vahvistaminen palvelivat myös muita päämääriä, joista merkittävimmät liittyivät katkenneen kokoomuksen yhtenäisyyden pönkittämiseen ja huomion kääntämiseen pois muista vuonna 1929 esiin työntyneistä ongelmista. Kommunismin muodostamaa uhkaa Suomen kansalliselle olemassaololle pyrittiin perustelemaan monelta eri kantilta. Kommunismin nähtiin rapauttavan kristillisen moraalin ja siveellisyyden, lisäävän yhteiskunnallisia levottomuuksia, heikentävän parlamentarismia sekä vaarantavan Suomen sotilaallisen turvallisuuden ja pyhäksi koetun etuvartiotehtävän. Antikommunismi yhdistyi läheisesti myös ideologisen venäläisvastaisuuden ääri-ilmiöön, ryssävihaan. Näihin eri ilmiöihin liittyvä "antikommunistinen diskurssi" oli siis yksi niistä perustoista, jonka päällä kokoomuksen poliittis-kansallinen identiteetti kehittyi 1920-luvun mittaan. Kevätkesän 1929 tuomien, lähes ylitsepääsemättömien vaikeuksien myötä antikommunistisen diskurssin merkitys kasvoi entisestään ja loi pohjan puolueen suhtautumiselle lapualaisvuosiin.

In this study the junction of Christian mission, Christian education and voluntary work are examined in the Christian student voluntary association Opiskelijain Lähetysliitto (OL), which is the Finnish successor to the Student Volunteer Movement. The main subjects are the structure and content of the mission education as one aspect of Lutheran education and the reasons for expressing the mission interest through voluntary work. The research questions are as follows: What kind of organization has the OL been? What has mission education been like in the OL? Why have the former chairpersons participated in the OL? How have purposiveness and intentionality arisen among the former chairpersons? The study is empirical despite having a historical and retrospective view, since the OL is explored during the period 1972 2000. The data consists of the OL s annual reports, membership applications (N=629) and interviews of all 25 former chairmen. Data is analysed by qualitative and quantitative content analysis in a partly inductive and partly deductive manner. The pedagogical framework arises from situational learning theory (Lave - Wenger 1991), which was complemented with the criteria for meaningful learning (Jonassen 1995), the octagon model of volunteer motivation (Yeung 2004) and the definitions of intentionality and purposiveness in the theory of teachers pedagogical thinking (Kansanen et al. 2000). The analysis of the archive data showed that the activities of the OL are reminiscent of those of the missions of the Finnish Evangelical Lutheran Church congregations. The biggest difference was that all OL participants were young adults, the age group that is the greatest challenge to the Church. The OL is therefore an interesting context in which to explore mission education and mission interest. The key result of the study was the forming of a model of mission educa-tion. The model has three educational components: values, goals and methods. The gist of the model is formed by the goals. The main goal is the arousing and strengthening of mission interest which has emotional, cognitive and practical aspects. The subgoals create the horizontal vertical and inward outward dimensions of the model, which are the metalevels of mission education. The subgoals reveal that societal and religious education may embody a missionary dimension when they are understood as missionary training. Further, a distinction between mission education and missionary training was observed. The former emphasizes the main goal of the model and the latter underlines the subgoals. Based on the vertical dimension of the model the study suggests that the definition of religious competence needs to be complemented with missional competence. Reasons for participating in the OL were found to be diverse as noted in other studies on volunteering and motivating factors, and were typical to young people such as the importance of social relations. The study created new motivational themes that occurred in the middle of the continuity newness and the distance proximity dimensions, which were not found in Yeung s research. Mission interest as voluntary work appeared as oriented towards one s own spirituality or towards the social community. On the other hand, mission interest was manifested as intentional education in order to either improve the community or to promote the Christian mission. In the latter case the mission was seen as a purpose in life and as a future profession. Keywords: mission, Christian education, voluntary work, mission education, mission interest, stu-dent movement

The title of the 14th International Conference on Electronic Publishing (ELPUB), “Publishing in the networked world: Transforming the nature of communication”, is a timely one. Scholarly communication and scientific publishing has recently been undergoing subtle changes. Published papers are no longer fixed physical objects, as they once were. The “convergence” of information, communication, publishing and web technologies along with the emergence of Web 2.0 and social networks has completely transformed scholarly communication and scientific papers turned to living and changing entities in the online world. The themes (electronic publishing and social networks; scholarly publishing models; and technological convergence) selected for the conference are meant to address the issues involved in this transformation process. We are pleased to present the proceedings book with more than 30 papers and short communications addressing these issues. What you hold in your hands is a by-product and the culmination of almost a Year long work of many people including conference organizers, authors, reviewers, editors and print and online publishers. The ELPUB 2010 conference was organized and hosted by the Hanken School of Economics in Helsinki, Finland. Professors Turid Hedlund of Hanken School of Economics and Yaşar Tonta of Hacettepe University Department of Information Management (Ankara, Turkey) served as General Chair and Program Chair, respectively. We received more than 50 submissions from several countries. All submissions were peer-reviewed by members of an international Program Committee whose contributions proved most valuable and appreciated. The 14th ELPUB conference carries on the tradition of previous conferences held in the United Kingdom (1997 and 2001), Hungary (1998), Sweden (1999), Russia (2000), the Czech Republic (2002), Portugal (2003), Brazil (2004), Belgium (2005), Bulgaria (2006), Austria (2007), Canada (2008) and Italy (2009). The ELPUB Digital Library, http://elpub.scix.net serves as archive for the papers presented at the ELPUB conferences through the years. The 15th ELPUB conference will be organized by the Department of Information Management of Hacettepe University and will take place in Ankara, Turkey, from 14-16 June 2011. (Details can be found at the ELPUB web site as the conference date nears by.) We thank Marcus Sandberg and Hannu Sääskilahti for copyediting, Library Director Tua Hindersson – Söderholm for accepting to publish the online as well as the print version of the proceedings. Thanks also to Patrik Welling for maintaining the conference web site and Tanja Dahlgren for administrative support.
