The purpose of this research is to draw up a clear construction of an anticipatory communicative decision-making process and a successful implementation of a Bayesian application that can be used as an anticipatory communicative decision-making support system. This study is a decision-oriented and constructive research project, and it includes examples of simulated situations. As a basis for further methodological discussion about different approaches to management research, in this research, a decision-oriented approach is used, which is based on mathematics and logic, and it is intended to develop problem solving methods. The approach is theoretical and characteristic of normative management science research. Also, the approach of this study is constructive. An essential part of the constructive approach is to tie the problem to its solution with theoretical knowledge. Firstly, the basic definitions and behaviours of an anticipatory management and managerial communication are provided. These descriptions include discussions of the research environment and formed management processes. These issues define and explain the background to further research. Secondly, it is processed to managerial communication and anticipatory decision-making based on preparation, problem solution, and solution search, which are also related to risk management analysis. After that, a solution to the decision-making support application is formed, using four different Bayesian methods, as follows: the Bayesian network, the influence diagram, the qualitative probabilistic network, and the time critical dynamic network. The purpose of the discussion is not to discuss different theories but to explain the theories which are being implemented. Finally, an application of Bayesian networks to the research problem is presented. The usefulness of the prepared model in examining a problem and the represented results of research is shown. The theoretical contribution includes definitions and a model of anticipatory decision-making. The main theoretical contribution of this study has been to develop a process for anticipatory decision-making that includes management with communication, problem-solving, and the improvement of knowledge. The practical contribution includes a Bayesian Decision Support Model, which is based on Bayesian influenced diagrams. The main contributions of this research are two developed processes, one for anticipatory decision-making, and the other to produce a model of a Bayesian network for anticipatory decision-making. In summary, this research contributes to decision-making support by being one of the few publicly available academic descriptions of the anticipatory decision support system, by representing a Bayesian model that is grounded on firm theoretical discussion, by publishing algorithms suitable for decision-making support, and by defining the idea of anticipatory decision-making for a parallel version. Finally, according to the results of research, an analysis of anticipatory management for planned decision-making is presented, which is based on observation of environment, analysis of weak signals, and alternatives to creative problem solving and communication.

The resources of health systems are limited. There is a need for information concerning the performance of the health system for the purposes of decision-making. This study is about utilization of administrative registers in the context of health system performance evaluation. In order to address this issue, a multidisciplinary methodological framework for register-based data analysis is defined. Because the fixed structure of register-based data indirectly determines constraints on the theoretical constructs, it is essential to elaborate the whole analytic process with respect to the data. The fundamental methodological concepts and theories are synthesized into a data sensitive approach which helps to understand and overcome the problems that are likely to be encountered during a register-based data analyzing process. A pragmatically useful health system performance monitoring should produce valid information about the volume of the problems, about the use of services and about the effectiveness of provided services. A conceptual model for hip fracture performance assessment is constructed and the validity of Finnish registers as a data source for the purposes of performance assessment of hip fracture treatment is confirmed. Solutions to several pragmatic problems related to the development of a register-based hip fracture incidence surveillance system are proposed. The monitoring of effectiveness of treatment is shown to be possible in terms of care episodes. Finally, an example on the justification of a more detailed performance indicator to be used in the profiling of providers is given. In conclusion, it is possible to produce useful and valid information on health system performance by using Finnish register-based data. However, that seems to be far more complicated than is typically assumed. The perspectives given in this study introduce a necessary basis for further work and help in the routine implementation of a hip fracture monitoring system in Finland.

This thesis studies binary time series models and their applications in empirical macroeconomics and finance. In addition to previously suggested models, new dynamic extensions are proposed to the static probit model commonly used in the previous literature. In particular, we are interested in probit models with an autoregressive model structure. In Chapter 2, the main objective is to compare the predictive performance of the static and dynamic probit models in forecasting the U.S. and German business cycle recession periods. Financial variables, such as interest rates and stock market returns, are used as predictive variables. The empirical results suggest that the recession periods are predictable and dynamic probit models, especially models with the autoregressive structure, outperform the static model. Chapter 3 proposes a Lagrange Multiplier (LM) test for the usefulness of the autoregressive structure of the probit model. The finite sample properties of the LM test are considered with simulation experiments. Results indicate that the two alternative LM test statistics have reasonable size and power in large samples. In small samples, a parametric bootstrap method is suggested to obtain approximately correct size. In Chapter 4, the predictive power of dynamic probit models in predicting the direction of stock market returns are examined. The novel idea is to use recession forecast (see Chapter 2) as a predictor of the stock return sign. The evidence suggests that the signs of the U.S. excess stock returns over the risk-free return are predictable both in and out of sample. The new "error correction" probit model yields the best forecasts and it also outperforms other predictive models, such as ARMAX models, in terms of statistical and economic goodness-of-fit measures. Chapter 5 generalizes the analysis of univariate models considered in Chapters 2 4 to the case of a bivariate model. A new bivariate autoregressive probit model is applied to predict the current state of the U.S. business cycle and growth rate cycle periods. Evidence of predictability of both cycle indicators is obtained and the bivariate model is found to outperform the univariate models in terms of predictive power.

The subjects of this study are Narcotics Anonymous (NA), a non-profit, peer-support-based fellowship, its recovery programme, and the former drug addicts who consider themselves members of the fellowship. The study data consist of episodic interviews (n=24) and questionnaires (n=212). In the collection of questionnaire data, survey research methods had to be applied judiciously. This study analyses NA members background and their substance abuse and treatment history, as well as factors that have contributed to or hindered their bonding with NA. A recovery model is presented that stems from NA s written and oral tradition, and which has been conceptualised into NA s recovery theory. At its simplest, NA s recovery theory can be described in two sentences: 1) There are drug dependent addicts who have an addiction disease. 2) Through an NA way of life, recovery is possible. In this study, addiction and addiction disease are described through recovery stories shared at NA. It also describes how the way of life offered by NA supports recovery from drug addiction, the way of life which recovering addicts have adopted, and how they have done so. The study also presents results that, based on the study data, emerge from participation in the NA programme, and describes how the NA recovery theory works in practice, i.e. how NA members utilise the tools provided by the fellowship and how the lives of recovering addicts change during their membership. Furthermore, this study also discusses criticism of NA. According to the study, NA affects the lives of recovering drug addicts in a number of ways. People of different ages and with a variety of personal, treatment and drug abuse histories seem to benefit from membership of NA. Viewed from the outside, NA may appear as strictly normative, but in practice each member can adapt the programme in a way that suits him/her best. Indeed, flexibility is one of the strengths of NA, but without more extensive knowledge of the fellowship, it is possible that the norms reflected in NA texts or the fanaticism of individual NA members may drive some people away. Due to the increasing number of NA members, the association is also able to provide more alternatives. This study confirms the view that peer support is important, as well as the fact that an official treatment system is required in parallel with peer support activities. NA can never fully replace professional support, neither should it be left with sole responsibility for recovering addicts.

According to Meno s paradox we cannot inquire into what we do not know because we do not know what we are inquiring into. There are many ways to interpret the paradox but the central issue about our ability to reach truth is a profound one. In the dialogue Meno, Plato presents the paradox and an outline of a solution which enables us to reach knowledge (epistēmē) through philosophical discussion. During the last century Meno has often been considered transitional between Socratic thinking and Plato s own philosophy, and thus the dialogue has not been adequately interpreted as an integrated whole. Therefore the distinctive epistemology of the dialogue has not gained due notice. In this thesis the dialogue is analysed as an integrated whole and the philosophical interpretation also takes into account its dramatic features. The thesis emphasises the role of language and definitions in acquiring knowledge. Among the results concerning these subjects is a new interpretation of Socrates s defintion of shape (schēma). The theory of anamnēsis all learning is recollection in the Meno is argued to answer the paradox philosophically although Plato s presentation also contains playful and ironic elements. The background of the way Plato presents his case is that he appreciated the fact that no argument can plausibly demonstrate that argumentation is able to reach truth. In the Meno, Plato makes the earliest explicit distinction between knowledge and true belief in the history of Western philosophy. He also gives a definition of knowledge which is the basis of the so called classical definition of knowledge as justified true belief. In the Meno, true beliefs become knowledge when someone ties them down by reasoning about the explanation. The analysis of the epistemology of the dialogue from this perspective gives an interpretation which integrates the central concepts of the epistemology in the dialogue elenchos, anamnēsis and hypothetical inquiry into a unified whole which contains a plausible argument according to which the ignorant can reach knowledge through discussion. The conception that emerges by such an analysis is interesting both from the point of view of current interests and that of the history of philosophy. The method of knowledge acquisition in the Meno can, for example, be seen as a predecessor of modern scientific methods. The Meno is the earliest Greek mathematical text that has survived in its original form. The analysis presented in the thesis of the geometric passages in the dialogue provides new results both concerning Socrates s geometry lesson with the slave and the example presenting the hypothetical method. Concerning the latter, a new interpretation is presented. Keywords: anamnēsis, epistēmē, knowledge, Meno s paradox, Plato

Tutkielman aiheena on ranskalaisen antropologin Claude Lévi-Straussin laajalti tunnettu malli, kulinaarinen kolmio, jonka Lévi-Strauss esitti alun perin primitiivistä mytologiaa käsittelevän tutkimusprojektinsa yhteydessä. Hänen mukaansa mallin avulla oli mahdollista esittää eräs tutkimuksen kohteena olevaa myyttiaineistoa jäsentävä syvärakenne. Myyttitutkimuksessaan Lévi-Strauss osoitti, että mallin avulla on mahdollista jäsentää ennen kaikkea erilaisia luonnon ja kulttuurin väliseen vastakkaisuuteen liittyviä ilmiöitä. Mallia on mahdollista käyttää myyttien ja niissä ilmenevän symbolisen ajattelun ohella myös konkreettisten ruokajärjestelmien analyysivälineenä. Mallia onkin sovellettu erilaisissa empiirisissä tutkimuksissa sekä määrättyihin empiirisiin ruokajärjestelmiin, että mitä erilaisimpiin kulttuurisiin ilmiöihin. Vaikka malli on ollut laajalti tunnettu ja synnyttänyt runsaasti keskustelua, ei siitä ole esitetty minkäänlaista systemaattista tulkintaa. Mallia koskeva keskustelu on ollut suurimmaksi osaksi kuvailevaa ja siihen kohdistetut kriittiset arviot ovat usein keskittyneet johonkin määrättyyn mallin aspektiin. Tutkielmani tehtävänä on täsmentää sitä, mistä mallissa on itse asiassa kyse ja millä tavalla Lévi-Strauss itse mallinsa mielsi. Tehtävä edellyttää mallin suhteuttamista sen taustalla olevaan teoreettiseen ja metodologiseen viitekehykseen. Tutkielmani ensimmäinen aineisto muodostuu Lévi-Straussin kulinaariseen kolmioon ja mallin taustalla olevaan viitekehykseen liittyvistä teksteistä. Erityisen keskeisiä lähteitä ovat artikkeli The Culinary Triangle ja myyttitutkimussarjan (Mythologiques) teokset. Tutkielman toisena tehtävänä on kartoittaa sitä, miten mallia on sovellettu erilaisissa empiirisissä tutkimuksissa ja millä tavalla nämä suhteutuvat Lévi-Straussin tapaan käyttää mallia ja hänen noudattamaansa tutkimusmetodologiaan. Keskityn kolmen mallia käyttävän tutkimuksen tarkastelemiseen ja erittelen sitä, millä tavalla ne suhteutuvat Lévi-Straussin tapaan käyttää mallia. Mallia soveltavat tutkimukset muodostavat opinnäytteeni toisen aineiston. Tutkielmani osoittaa, että malli on yleisestä luonteestaan johtuen altis erilaisille tulkinnoilla ja sovellusmahdollisuuksille. Tuon myös esille sen, millaisia reunaehtoja mallin soveltamiseen yleisesti liittyy ja millaisia seikkoja on otettava huomioon, kun mallia sovelletaan nyky-yhteiskuntiin. Vaikka mallia on mahdollista soveltaa hyvin erilaisiin ilmiöihin, ei sen avulla ole mahdollista käsitellä monia yhteiskuntatieteiden kannalta keskeisiä kysymyksiä.

11β-hydroksisteroididehydrogenaasientsyymit (11β-HSD) 1 ja 2 säätelevät kortisonin ja kortisolin määrää kudoksissa. 11β-HSD1 -entsyymin ylimäärä erityisesti viskeraalisessa rasvakudoksessa aiheuttaa metaboliseen oireyhtymän klassisia oireita, mikä tarjoaa mahdollisuuden metabolisen oireyhtymän hoitoon 11β-HSD1 -entsyymin selektiivisellä estämisellä. 11β-HSD2 -entsyymin inhibitio aiheuttaa kortisonivälitteisen mineralokortikoidireseptorien aktivoitumisen, mikä puolestaan johtaa hypertensiivisiin haittavaikutuksiin. Haittavaikutuksista huolimatta 11β-HSD2 -entsyymin estäminen saattaa olla hyödyllistä tilanteissa, joissa halutaan nostaa kortisolin määrä elimistössä. Lukuisia selektiivisiä 11β-HSD1 inhibiittoreita on kehitetty, mutta 11β-HSD2-inhibiittoreita on raportoitu vähemmän. Ero näiden kahden isotsyymin aktiivisen kohdan välillä on myös tuntematon, mikä vaikeuttaa selektiivisten inhibiittoreiden kehittämistä kummallekin entsyymille. Tällä työllä oli kaksi tarkoitusta: (1) löytää ero 11β-HSD entsyymien välillä ja (2) kehittää farmakoforimalli, jota voitaisiin käyttää selektiivisten 11β-HSD2 -inhibiittoreiden virtuaaliseulontaan. Ongelmaa lähestyttiin tietokoneavusteisesti: homologimallinnuksella, pienmolekyylien telakoinnilla proteiiniin, ligandipohjaisella farmakoforimallinnuksella ja virtuaaliseulonnalla. Homologimallinnukseen käytettiin SwissModeler -ohjelmaa, ja luotu malli oli hyvin päällekäinaseteltavissa niin templaattinsa (17β-HSD1) kuin 11β-HSD1 -entsyymin kanssa. Eroa entsyymien välillä ei löytynyt tarkastelemalla päällekäinaseteltuja entsyymejä. Seitsemän yhdistettä, joista kuusi on 11β-HSD2 -selektiivisiä, telakoitiin molempiin entsyymeihin käyttäen ohjelmaa GOLD. 11β-HSD1 -entsyymiin yhdisteet kiinnittyivät kuten suurin osa 11β-HSD1 -selektiivisistä tai epäselektiivisistä inhibiittoreista, kun taas 11β-HSD2 -entsyymiin kaikki yhdisteet olivat telakoituneet käänteisesti. Tällainen sitoutumistapa mahdollistaa vetysidokset Ser310:een ja Asn171:een, aminohappoihin, jotka olivat nähtävissä vain 11β-HSD2 -entsyymissä. Farmakoforimallinnukseen käytettiin ohjelmaa LigandScout3.0, jolla ajettiin myös virtuaaliseulonnat. Luodut kaksi farmakoforimallia, jotka perustuivat aiemmin telakointiinkin käytettyihin kuuteen 11β-HSD2 -selektiiviseen yhdisteeseen, koostuivat kuudesta ominaisuudesta (vetysidosakseptori, vetysidosdonori ja hydrofobinen), ja kieltoalueista. 11β-HSD2 -selektiivisyyden kannalta tärkeimmät ominaisuudet ovat vetysidosakseptori, joka voi muodostaa sidoksen Ser310 kanssa ja vetysidosdonori sen vieressä. Tälle vetysidosdonorille ei löytynyt vuorovaikutusparia 11β-HSD2-mallista. Sopivasti proteiiniin orientoitunut vesimolekyyli voisi kuitenkin olla sopiva ratkaisu puuttuvalle vuorovaikutusparille. Koska molemmat farmakoforimallit löysivät 11β-HSD2 -selektiivisiä yhdisteitä ja jättivät epäselektiivisiä pois testiseulonnassa, käytettiin molempia malleja Innsbruckin yliopistossa säilytettävistä yhdisteistä (2700 kappaletta) koostetun tietokannan seulontaan. Molemmista seulonnoista löytyneistä hiteistä valittiin yhteensä kymmenen kappaletta, jotka lähetettiin biologisiin testeihin. Biologisien testien tulokset vahvistavat lopullisesti sen kuinka hyvin luodut mallit edustavat todellisuudessa 11β-HSD2 -selektiivisyyttä.

Agriculture is an economic activity that heavily relies on the availability of natural resources. Through its role in food production agriculture is a major factor affecting public welfare and health, and its indirect contribution to gross domestic product and employment is significant. Agriculture also contributes to numerous ecosystem services through management of rural areas. However, the environmental impact of agriculture is considerable and reaches far beyond the agroecosystems. The questions related to farming for food production are, thus, manifold and of great public concern. Improving environmental performance of agriculture and sustainability of food production, sustainabilizing food production, calls for application of wide range of expertise knowledge. This study falls within the field of agro-ecology, with interphases to food systems and sustainability research and exploits the methods typical of industrial ecology. The research in these fields extends from multidisciplinary to interdisciplinary and transdisciplinary, a holistic approach being the key tenet. The methods of industrial ecology have been applied extensively to explore the interaction between human economic activity and resource use. Specifically, the material flow approach (MFA) has established its position through application of systematic environmental and economic accounting statistics. However, very few studies have applied MFA specifically to agriculture. The MFA approach was used in this thesis in such a context in Finland. The focus of this study is the ecological sustainability of primary production. The aim was to explore the possibilities of assessing ecological sustainability of agriculture by using two different approaches. In the first approach the MFA-methods from industrial ecology were applied to agriculture, whereas the other is based on the food consumption scenarios. The two approaches were used in order to capture some of the impacts of dietary changes and of changes in production mode on the environment. The methods were applied at levels ranging from national to sector and local levels. Through the supply-demand approach, the viewpoint changed between that of food production to that of food consumption. The main data sources were official statistics complemented with published research results and expertise appraisals. MFA approach was used to define the system boundaries, to quantify the material flows and to construct eco-efficiency indicators for agriculture. The results were further elaborated for an input-output model that was used to analyse the food flux in Finland and to determine its relationship to the economy-wide physical and monetary flows. The methods based on food consumption scenarios were applied at regional and local level for assessing feasibility and environmental impacts of relocalising food production. The approach was also used for quantification and source allocation of greenhouse gas (GHG) emissions of primary production. GHG assessment provided, thus, a means of crosschecking the results obtained by using the two different approaches. MFA data as such or expressed as eco-efficiency indicators, are useful in describing the overall development. However, the data are not sufficiently detailed for identifying the hot spots of environmental sustainability. Eco-efficiency indicators should not be bluntly used in environmental assessment: the carrying capacity of the nature, the potential exhaustion of non-renewable natural resources and the possible rebound effect need also to be accounted for when striving towards improved eco-efficiency. The input-output model is suitable for nationwide economy analyses and it shows the distribution of monetary and material flows among the various sectors. Environmental impact can be captured only at a very general level in terms of total material requirement, gaseous emissions, energy consumption and agricultural land use. Improving environmental performance of food production requires more detailed and more local information. The approach based on food consumption scenarios can be applied at regional or local scales. Based on various diet options the method accounts for the feasibility of re-localising food production and environmental impacts of such re-localisation in terms of nutrient balances, gaseous emissions, agricultural energy consumption, agricultural land use and diversity of crop cultivation. The approach is applicable anywhere, but the calculation parameters need to be adjusted so as to comply with the specific circumstances. The food consumption scenario approach, thus, pays attention to the variability of production circumstances, and may provide some environmental information that is locally relevant. The approaches based on the input-output model and on food consumption scenarios represent small steps towards more holistic systemic thinking. However, neither one alone nor the two together provide sufficient information for sustainabilizing food production. Environmental performance of food production should be assessed together with the other criteria of sustainable food provisioning. This requires evaluation and integration of research results from many different disciplines in the context of a specified geographic area. Foodshed area that comprises both the rural hinterlands of food production and the population centres of food consumption is suggested to represent a suitable areal extent for such research. Finding a balance between the various aspects of sustainability is a matter of optimal trade-off. The balance cannot be universally determined, but the assessment methods and the actual measures depend on what the bottlenecks of sustainability are in the area concerned. These have to be agreed upon among the actors of the area

The starting point of the study was that good teaching requires a teacher to be aware of the sources of his or her pedagogical decisions; that is, personal values, beliefs and understandings. From this perspective, a teacher s professional development refers to a process of extending one s self-knowledge. The aim of this study was to promote student teachers' professional development with the help of identity work. Identity work refers to reflecting on both personal and professional experiences. Identity work consists of student teachers self-reflection on their life experiences (self-identity) and video diary-based reflection on their classroom practice (professional identity). The research questions of the study were 1) how is identity work manifested by the participants? and 2) what is the potential of identity work in promoting student teachers professional development? The research data was collected from four student teachers in the academic year 2007-2008; the research group had 24 meetings during the research process. Student teachers take part in a multimode teacher education programme, where students work as ordinary teachers in schools during their university studies. The data collection was conducted by using two methods: participants narratives based on autobiographical writings and video diaries based on participants lessons. Narrative research data was analysed by employing qualitative methods and strategies as they were needed in the research. The research results revealed four different ways of working with identities, each of them revealing different aspects of and approaches to identity work. The results also showed that identity work has the potential to promote professional development. As the research progressed, there were visible changes in the participants reflection. However, despite encouraging results, some issues should be critically questioned. Although reflection sounds attractive and fruitful as a tool for promoting professional development, there are also difficulties and obstacles. On the basis of the results, a proposal for promoting student teachers professional development is offered. Keywords: Teacher identity, identity work, reflection, teacher professional development

ABSTRACT The diocese as the agent and advocate of diaconial work. The development of diaconial work in the Mikkeli diocese 1945–1991. The roots of Finnish diacony are in the individual devotional life of Pietism. An acting faith had to be evident in acts of love. Following German institutional diacony, diaconial institutions were established in Finland until congregational diacony emerged alongside these institutions in the 1890s. Pastor Otto Aarnisalo acted as a pathfinder in this. He aimed to unite diacony with the Church and the life of the congregation. Diacony had been based on the idea of volunteering to separate it from statutory social work. In 1944 the church law was amended, which made diacony the concern of every member of the congregation. In the years immediately following the Second World War, discussion took place in the Church of Finland about the direction that diacony should take. In the consequential debate, caritative services overcame social diacony. The diocese administration moved to Mikkeli in 1945, when the majority of the Vyborg diocese became part of the USSR in the armistice negotiations. The Mikkeli diocese acted in its diaconial work with the same objectives as the diaconial solutions of the whole church. The acting principle of the diocese diacony became a form of helping which emphasised assistance of the individual. Especially from the 1960s onwards, the country's industrialisation and the reduction of agricultural trade had an effect on the Mikkeli diocese. The diocese administration, specifically Bishop Martti Simojoki and his successor Osmo Alaja, aimed to open up connections to the political left and people working in industry. At least indirectly this helped the diaconial work in industrial localities. In the Mikkeli diocese, a diaconial committee was established in 1971, and its work was overseen by the diocesan chapter of the bishop's office. This enabled the work of the diocese to be organised for the different areas of diacony. Previously, the diaconial work of the Finnish church had primarily been in nursing. The Health Insurance Law of 1972 brought a change to this when the responsibility for health services was transferred to the municipalities. Diacony began to move towards a psychological and spiritual emphasis. Beginning in the 1970s, the diocese started holding diaconial themed days at prescribed intervals. Although these did not result in great realignments, they did help clarify the direction that diacony would take. Large international collections were also carried out, especially in the 1980s. At the same time, socio-ethical activity vitalised and diversified Christian services. The idea that every member of the congregation should practice diacony was a strong factor in the Mikkeli diocese as well. The diocese's vision for diacony was holistic; Christian service was the responsibility of every member of the congregation. During the period of study (1945–1991), the theology of diacony was rather tenuous. Bishop Kalevi Toiviainen, however, brought forth the viewpoint of church doctrine and officially sanctioned theology. Diacony was part of the complete faith of the Church.

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.

Words as Events introduces the tradition of short, communicative rhyming couplets, the mantinádes, which are still sung and recited in a variety of performance situations on the island of Crete. The local focus on communicative economy and artistry is further examined in an in-depth analysis of the processes and ideals of composition. Short genres of oral poetry have been widely neglected in folklore research; however, their demand for structural and semantic coherence as well as their dialogic nature appeals to very different human needs from those of the longer poems. In contemporary Crete, poems also appear in written contexts, they are submitted to modern mass media, and people widely exchange them as text messages. By striving to understand the tradition during a period of change, this study analyzes the larger principles that ground the communication, self-expression and creativity in the genre. The aim of this research is thus twofold: to present this specific register of dialogic oral poetry as well as to create a theoretical approach sensitive to the creativity of such short registers. The study is based on long-term ethnographic fieldwork conducted in Crete between the years 1997 2009. An important aspect of the methodology was to create long-term ties with a number of key-informants who composed mantinádes. The interdisciplinary theoretical and methodological basis for this analysis is in the contemporary Finnish and international research on oral poetry and on anthropological research on communicative speech genres. These theoretical insights are extended by addressing questions of spontaneity and individual agency. Since mantinádes are at the same time a model for composition and a reserve of poems in fixed form, the aesthetics and objectives of performance and composition are also plural. In a traditional singing event, the basic motivation for the singers is to provide a meaningful contribution to a selected theme, which is the shared topic of the poetic dialogue. Consequently, similar topics giving rise to poetic associations can be encountered during various moments of everyday life: the dialogic nature is embodied in the tradition to such degree that it also arises in the performances and composition of single poems and outside of any institutionalized performance arenas. Therefore, as this study discusses in detail, even the apparently non-contextualized poems recited between locals or occurring in the contemporary mass media arenas, are understood and evaluated as utterances that provide an individual perspective within a certain dialogue.

Tämän tutkielman tarkoituksena on kuvailla lasten ja nuorten kokemuksia heidän osallistuttuaan perheineen lastensuojelun alkuvaiheen arviointiin eli lastensuojelutarpeen selvitykseen. Tarkastelen tutkielmassa lasten ja nuorten kokemuksia osallisuuden näkökulmasta. Tavoitteena on, että tämä tutkielma kertoisi lastensuojelutarpeen selvityksestä työkäytäntönä ja lisäisi tietoa siitä, miten lastensuojelu on onnistunut tavoitteessaan lisätä lasten ja nuorten osallisuuden kokemuksia ja lapsilähtöisyyttä lastensuojelun työkäytäntöihin ja erityisesti asiakkuuden alkuvaiheen selvitystyöhön. Tutkielmani on laadullinen tutkimus, jonka aineisto on saatu haastattelemalla yhdeksää 10–17-vuotiasta lasta ja nuorta, jotka ovat osallistuneet lastensuojelutarpeen selvitykseen vuosien 2009–2010 aikana. Lastensuojeluasiakkuus oli päättynyt arvioinnin jälkeen neljän nuoren osalta ja viiden nuoren kohdalla oli päädytty jatkamaan asiakkuutta lastensuojelun avohuollossa. Tutkimusaineiston analysoinnissa käytin temaattista sisällönanalyysiä. Thomasin malli osallisuuden ulottuvuuksista auttoi jäsentämään osallisuuden käsitettä ja lasten ja nuorten puhetta. Tutkimusaineistossa osallisuuden kokemuksen osa-alueiksi muodostuivat 1) tiedon saaminen asiakkuuden alkuvaiheesta ja syistä, jotka johtivat lastensuojelutarpeen selvitykseen, 2) kuulluksi tuleminen ja 3) vaikuttamisen mahdollisuus selvitystyön aikana. Useimmat lapset ja nuoret antoivat kiitettävän arvosanan tiedon saannistaan. Kuulluksi tuleminen edellytti mahdollisuutta itsensä ilmaisemiseen ja tuen saamista siihen. Lastensuojeluun kehitetyt osallistavat menetelmät olivat auttaneet oman mielipiteen kertomisessa. Vaikuttamisen mahdollisuus tarkentui mahdollisuudeksi vaikuttaa siihen, ketkä osallistuivat selvitykseen sekä mahdollisuudeksi vaikuttaa selvityksen sisältöön. Vaikuttamisen mahdollisuuteen sisältyi lisäksi mahdollisuus olla osallistumatta. Osallisuuden kokemukseen vaikuttivat myös se, näkyikö nuoren oma mielipide yhteenvetotekstissä ja se, oliko nuori selvillä asiakassuunnitelman tavoitteista. Kuulluksi tuleminen oli vaikuttanut nuorten käsityksiin lastensuojelusta ja muuttanut niitä positiivisemmiksi. Kuulluksi tulemisen ja osallisuuden kokemuksen seurauksena nuoret kokivat pääsääntöisesti hyötyneensä alkuvaiheen interventiosta. Eniten nuoret mainitsivat emotionaalisesti merkittäviä muutoksia, kuten luottamuksen ja yhteisen keskustelun lisääntymisen perheenjäsenten välillä ja hyväksytyksi tulemisen kokemuksia. Selvitykseen osallistumisen koettiin vaikuttaneen sekä lasten ja nuorten omaan käyttäytymiseen että vanhempien asennoitumiseen positiivisella tavalla.

Tutkimus on kvalitatiivinen tapaustutkimus. Tutkimuksen tarkoitus on selvittää mitkä ovat OP -Pohjola-ryhmän tärkeimmät sidosryhmät, millä perusteella sidosryhmät erottuvat muista organisaation ympäristössä toimivista tahoista, sekä millaisten ominaisuuksien perusteella sidosryhmien tärkeyttä arvioidaan OPPohjola- ryhmän näkökulmasta. Sidosryhmät ovat yrityksen ympäristössä toimivia ryhmiä tai tahoja, joiden asema sidosryhmänä perustuu yleensä niiden kykyyn vaikuttaa yrityksen menestykseen (esimerkiksi asiakkaat) tai oikeutettuun asemaan yrityksessä (esimerkiksi omistajat ja henkilökunta). Viimeaikaisissa sidosryhmiin keskittyvässä tutkimuksessa on tunnustettu sidosryhmien merkitys yritysten menestymisen kannalta. Toisaalta kaikkien sidosryhmien huomioimiseen perustuvalla liikkeenjohtamisella on myös eettisiä perusteita. Yleistyneen käsityksen mukaan yrityksellä on vastuuta myös muita tahoja, kuin omistajiaan kohtaan. Sidosryhmien laaja-alainen huomiointi on siis osa vastuullista liiketoimintaa ja sitä kautta yritysten yhteiskuntavastuun lähtökohta. Sidosryhmiä on pyritty määrittelemään lukuisilla eri tavoilla eri tutkijoiden toimesta. Erilaiset määritelmät ovat hämärtäneet sidosryhmän käsitettä jopa niin, että käytännössä kaikki yrityksen ympäristössä toimivat tahot voidaan nähdä yrityksen sidosryhmiksi. Yrityksen on kuitenkin hyödyllistä tunnistaa sen tärkeimmät sidosryhmät, jotta se voi toteuttaa suunnitelmallista sidosryhmäpolitiikka näihin tahoihin päin. Tämä tutkimus pyrkii luomaan yleiskuvan siitä, mitkä ovat OP-Pohjola-ryhmälle sen keskeiset sidosryhmät ja miksi. Tutkimus perustuu OP-Pohjola-ryhmässä työskentelevien henkilöiden teemahaastatteluihin. Haastattelumateriaalia on analysoitu käyttäen apuna sisällönanalyysiä ja sisällön erittelyä. Tutkimuksen teoreettisena viitekehyksenä toimii Mitchellin, Anglen ja Woodin ns. sidosryhmien identifikaation malli, jonka mukaan sidosryhmän tärkeys yrityksen näkökulmasta perustuu siihen, onko sidosryhmällä valtaa, legitiimi asema tai kiireellisiä vaateita suhteessa yritykseen. Sidosryhmien identifikaation mallin mukainen analyysi osoitti, että OP-Pohjola- ryhmän tärkeimmät sidosryhmät ovat asiakkaat sekä lainsäätäjät ja viranomaiset. Muita OP-Pohjola- ryhmän sidosryhmiä ovat omistajat, hallinto, media, henkilökunta, kansalaisjärjestöt ja palkansaajajärjestöt. Sidosryhmän tärkeyteen OP-Pohjola- ryhmän näkökulmasta näytti vaikuttavan eniten sidosryhmän kyky vaikuttaa organisaation menestykseen. Tämä kyky saattoi perustua joko välilliseen tai välittömään valtaa tai esimerkiksi asiantuntemukseen finanssialasta. Se, kuinka ”äänekäs” sidosryhmä on, ei yksistään vaikuta sidosryhmän tärkeyteen yrityksen näkökulmasta. Tutkimuksessa käytettiin lähteinä enimmäkseen 2000- luvulla tehtyjä sidosryhmätutkimuksia sekä teoreettista kirjallisuutta sidosryhmiin ja yritysten vastuullisuuteen liittyen.
