Information structure and Kabyle constructions Three sentence types in the Construction Grammar framework The study examines three Kabyle sentence types and their variants. These sentence types have been chosen because they code the same state of affairs but have different syntactic structures. The sentence types are Dislocated sentence, Cleft sentence, and Canonical sentence. I argue first that a proper description of these sentence types should include information structure and, second, that a description which takes into account information structure is possible in the Construction Grammar framework. The study thus constitutes a testing ground for Construction Grammar for its applicability to a less known language. It constitutes a testing ground notably because the differentiation between the three types of sentences cannot be done without information structure categories and, consequently, these categories must be integrated also in the grammatical description. The information structure analysis is based on the model outlined by Knud Lambrecht. In that model, information structure is considered as a component of sentence grammar that assures the pragmatically correct sentence forms. The work starts by an examination of the three sentence types and the analyses that have been done in André Martinet s functional grammar framework. This introduces the sentence types chosen as the object of study and discusses the difficulties related to their analysis. After a presentation of the state of the art, including earlier and more recent models, the principles and notions of Construction Grammar and of Lambrecht s model are introduced and explicated. The information structure analysis is presented in three chapters, each treating one of the three sentence types. The analyses are based on spoken language data and elicitation. Prosody is included in the study when a syntactic structure seems to code two different focus structures. In such cases, it is pertinent to investigate whether these are coded by prosody. The final chapter presents the constructions that have been established and the problems encountered in analysing them. It also discusses the impact of the study on the theories used and on the theory of syntax in general.

The subject of this work is the mysticism of Russian poet, critic and philosopher Vjacheslav Ivanov (1866-1949). The approach adopted involves the textual and discourse analysis and findings of the history of ideas. The subject has been considered important because of Ivanov's visions of his dead wife, writer Lydia Zinovieva-Annibal, which were combined with audible messages ("automatic writings"). Several automatic writings and descriptions of the visions from Ivanov's archive collections in St.Petersburg and Moscow are presented in this work. Right after the beginning of his hallucinations in the autumn of 1907, Ivanov was totally captivated by the theosophical ideas of Anna Mintslova, the background figure for this work. Anna Mintslova, a disciple of Rudolf Steiner's Esoteric School, offered Ivanov the theosophical concept of initiation to interpret paranormal phenomena in his intimate life. The work is divided into three main chapters, an introduction and aconclusion. The first chapter is called The Mystical Person: Anthropology of Ivanov and describes the role of the inner "Higher Self" in Ivanov's views on the nature of human consciousness. The political implications of the concepts, "mystical anarchism" and "sobornost" (religious unity) are also examined. The acquaintance and contacts with Anna Mintslova during 1906-1907 gave a framework to Ivanov's search for an organic society and personal religious experience. The second part, Mystics of Initiation and Visionary Aesthetics describes the influence of the initiation concept on Ivanov's aesthetic views (mainly "realistic symbolism"). On the other hand, some connections between the imagery of his visions and symbols in his verses of that period are established. Since Mintslova represented the ideas of Rudolf Steiner in Russia, several symbols shared by Steiner and Ivanov ("rose", "rose and cross") have been another subject of investigation. The preference for strict verse form in the lyrics of Ivanov's visionary period is interpreted as an attempt to place his own poetic creation within two traditions, a mystical and literary one. The third part of this work, Mystics of Hope and Terror, examines Ivanov's conception of Russia in connection with Mintslova's ideas of occult danger from the East. Ivanov's view of the "Russian idea" and his nationalistic idea during World War I are considered as a representation of the fear of the danger. Ivanov's interpretation of the October revolution is influenced by the theosophical concept of the "keeper of the threshold" which occurs in the context of the discourse of occult danger.

My PhD-thesis Body Images! Psychoanalytical Analysis of Finnish Performance and Body Art in the 1980s and 1990s considers Finnish performance and body art performed mainly by visual artists. In Part I, I chart the historical construction of performance art and its extension since the beginning of the 21st century. There are several wievs of the historical background of performance art. I introduce three different genealogies of performance art. One is Rose-Lee Goldberg s view. She connects performance art with the European avant-garde already at the beginning of the 20th century from futurists and dadaists to Russian avant-garde and the Bauhaus. I prefer to present performance art as contemporary art, which began to take shape in connection with visual arts in the 1950s and 1960s. The focus on the body is apparent in nearly all performance art. Nevertheless, throug the concept of body art I want to empasize the artist s body as the place of art. Body art (as part of performance art) functions as thematic and interpretive concept, which allows me to focus on performances where the questions of body image, narcissism, desire, language and pleasure are incorporated in particular intensive ways. In Part II, I explore the arrival of performance art in Finnish visual arts in the 1980s. I study the new generation s relation to earlier Finnish happenings (1960s) and performative actions in 1970 s. I briefly introduce performance groups of the 1980s art scene and consider their reception in media. The main focus is on the group Jack Helen Brut, in which I see many similarities to the so- called Theatre of Images. The goal of this part II is to provide historical context for the performance analysis that follows. In Part III, I develop the concept of body image which is my main theoretical term. The concept of body image is used according to Lacanian psychoanalytical theory, especially his considerations of mirror stages. My first mapping of body image, which I call imaginary body image, is based on Lacan s famous mirror stage article (1949). According to my reading, body image is narcistic and aggressive. The important concepts here are ego, imaginary, méconnaisance and alienation. In 1953 Lacan began to develop different version on mirror stage, in which he emphasized the primacy of symbolic dimension. It is not image, but language which constructs the foundations of body image. Central concepts in this chater are Other as language, ego-ideal, demand and desire. In the last chapter I connect the third version of the mirror stage to concepts of gaze, phantasy, real, jouissance and object a. In previous chapters I had considered body image in relation to ego. Now I explore it in relation to subject. In my reading the body image is fragile phenomen, which oscillates between yearning for coherence and phantasies of fragmented images. Part IV of the thesis begins with an introduction to the central concepts and debates in performace studies over the last few decades. Important concepts are presence, performativity and theatricality. The main substance of my thesis, however, is the performance analysis, which focuses on works by three Finnish artists and one Finnish group. The first analysis concerns the performance (1992) of Kimmo Schroderus. I discuss the relationship between narcissism and body art and the changes in demands projected on body images of men in recent decades in a Euro-American context. I also explore this performance in relation to the myth of Narcissus, which I reinterpret through Narcissus s aggression against his own body. The group Homo S is the main subject of the next analysis. I discuss the relationship between feminist art and performance art, especially in the United States in the 1960s and 1970s. Homo S is different from this early performance art because of its anarchism, humor and rejection of all ideals. Homo S characterizes its performance Body Body (1983) as liberating vulgar feminism . Sociality and performance of erotic relations between women are central in Body Body. Pia Lindman s performances are the subjects of my third analysis. I study three of her performances: Olen muoto (1993), 17 and in love (1994) and Arranged views (1995). I interpret these performances as efforts to disperse the imaginary and symbolic structures of the body image. She constructs the peculiar object a and phantasy space of her own. In the last analysis I move from questions of image and gaze to a study of language, sound and jouissance. I discuss at a general level the performance of orality and helplesness (Hilflosigkeit) in body art. The central elements in Pentti Otto Koskinen s performances are the ear, listening and receptive gestures and postions. Perseveraatio (1998) can be understood representing as submission to the super-ego s power, which compels one to enjoy. I examine particularly closely the performance Maissi on hyvää ei missään nimessä maissia (1995), which I interpret as the return of a baby s body image to the liminal site of choice: language or jouissance?

The aim of this research is to define what kind of characters and images of teachers appear in Finnish school novels describing social changes and educational political reform from the 1930s to the 1990s written by teachers, particularly grammar school teachers. As comparison material, I use school novels written by Swedish school teachers, in which the changes in Swedish society and educational system and their expressions in the characters of teachers of the school novels are studied. The main focus of my study is centred particularly on school novels in which the images of grammar school teachers are described during times of school reform. From these starting points, the main objectives of the study are novels written by Finnish school teachers Anneli Toijala and Sampo Haahtela and Swedish school teacher Hugo Swensson, who was inspired by Haahtela. The research is qualitative multidisciplinary case analysis. The research method is content analysis, and the approach is hermeneutic. The research is divided into eight main chapters. After the introduction I introduce the essential concepts of my research. In the third main chapter I define the research function. In that context, besides the research objectives, I introduce former research on character description in literature, I define the methodological solutions with grounds and present the research material. Both literary research methods and sociological terminology are applied in the research alongside with pedagogical research. The research results show that images of teachers are diverse. At one end of the spectrum these represent immature pictures of teachers withdrawn into the routines of everyday life; at the other, they advance and reflect the reformist teacher. This becomes clearly evident when comparing the teacher "monsters" of the classic authors to the educational optimists at the end of the 20th century. The results show that the images of teachers in school novels are almost without exception coherent, psychologically credible and consistent, and hardly any different from the images of teachers in the Swedish school novels used as comparison material. On the contrary, plenty of similarities are found. The comprehensive school reform, educational political discourse and teachers' feelings are realistically clarified in the school novels that describe the period. Keywords: literature image, school reform, school novel, teacher image, reflection, internal co-operation in school

A View into the World of Kitchen: Development and retention of a leading position in the market of kitchen interiors - a case study of 20 years. This study focuses on the development of a kitchen interiors company, presently called Novart Inc., into the leading company of the industry from 1980´s to the present. The objective of the study is to describe the effects of strategic choices, the decisions of the management and the owner´s direction and control to the build up and the retaining of the leading position in the market. From theory point of view, strategic choices refer to com-pany purchases as corporate-level strategies, and business and marketing strategies. The empirical research was carried out in two phases and it is based on various company documents and records, and on the intensive interviews of seven key executives in the company. An abductive research design was utilized. The company gained the leading position in the kitchen market in Finland by company purchases, and the company has been able to retain the position. Firstly the goal was to expand to retail market and, secondly, the company has maintained the balance of supply and demand by closing the purchased production units when needed. The simultaneous use of these two strategic goals is a kind of a new observation, and the strategy may be suitable only for market leaders. During the latter part of the research period the strategy of com-pany purchases has been abandoned and the leading position in the market has been main-tained by developing systematically business and marketing capability. In the business and marketing strategies the distribution channels and the brands have been emphasized. During the research period the company has almost totally abandoned the long distribution channels and started to use its own channels built and named after the main brands. These are A la Carte, Parma and Petra. At the moment, in the beginning of the 21st century, a new distribution channel, the concept of the Kitchen World, is being built in addition to the channels mentioned above. The management´s decision making and the implementation the decisions have been well-considered. The executives emphasized the valuing of the importance of the decisions dif-ferently except the two decisions named the most important ones, i.e., the decisions to start own production of the raw material and to concentrate the business only to one company. The executive staff has also succeeded in managing crisis and threats of bankruptcy, and the company has been managed profitable. During all the four terms of ownership: Puolimatka Corporation, the Hankkija/Novera Corporation, the ownership period of the "bank", and the Nobia Corporate the ownership direction and control has been somewhat different. All the owners have paid attention to economic issues. The direction of cash flows and investments was at its strongest during the Hankkija/Novera term. For the last owner Nobia the production and marketing of the kitchen interiors has been the core business, which thus has strengthened the business and marketing capabilities of the target company of this research. A common denominator during all the four terms of ownership has been owners' trust gained by the professional skills of the management of the target company. This has lead to greater independence of the management of the company and less owners´ direction. Keywords: leading position, marketing strategy, management decisions, acquisition, corporate governance

In my dissertation I have studied St Teresa (1515-1582) in the light of medieval mystical theories. I have two main levels in my research: historical and theological. On the historical level I study St Teresa s personal history in the context of her family and the Spanish society. On the theological level I study both St Teresa s mysticism and her religious experience in the light of medieval mysticism. St Teresa wrote a book called Life , which is her narrative autobiography and story about her mystical spiritual formation. She reflected herself through biblical texts interpreting them in the course of the biblical hermeneutics like allegory, typology, tropology and anagogy. In addition to that she read others life stories from her period of time, but reflected herself only slightly through the sociological point of view. She used irony as a means to gain acceptance to her authority and motive to write. Her position has been described as a double bind because of writing at the request of educated men and to the non-educated women as she herself was uneducated. She used irony as a means to achieve valuation to women, to gain negative attributes connected to them and to gain authority to teach them mystical spirituality, the Bible and prayer. In this ironic tendency she was a feminist writer. In order to understand medieval mysticism I have written in the first chapter a review of the main trends in medieval mysticism in connection with the classical emotional theories. Two medieval mystical theories show an important role in St Teresa s mysticism. One is love mysticism and the other is the three partite way of mysticism (purification, illumination and union). The classic-philosophical emotional theories play a role in both patterns. The theory of love mysticism St Teresa interpreted in the traditional way stressing the spiritual meaning of love in connexion with God and neighbors. Love is an emotion, which is bound with other emotions, but all objects of love don t strengthen spiritual love. In the three partite way of mysticism purification means to find biblical values in life and to practice meditative self-knowledge theologically interpreted. In illumination human understanding has to be illuminated by God and united to mystical knowledge from God. St Teresa considered illumination a way to learn things. Illumination has also psychological aspects like recognition of many trials and pains, which come from life on earth. Theologically interpreted in illumination one should die to oneself, let oneself be transformed and renewed by God. I have also written a review of the modern philosophical discussion on personal identity where memory and mental experiences are important creators of personal identity. St Teresa bound medieval mystical teaching together with her personal religious experience. Her personal identity is by its character based on her narrative life story where mental experiences play important role. Previous researchers have labelled St Teresa as an ecstatic person whose experiences produced ecstatic phenomena to the mysticism. These phenomena combined with visions have in one respect made of her a person who has brought physical and visionary tendencies to theology. In spite of that she also represents a modern tendency trying to give words to experiences, which at first seem to be exceptional and extreme and which are easily interpreted as one-sided either physical or sexual or unsaid. In other respect I have stressed the personality of St Teresa that was represented as both strong and weak. The strong personality for her is demonstrated by religious faith and in its practice. The weak personality was for her a natural personal identity. St Teresa saw a unifying aspect in almost all. Firstly, her mysticism was aimed towards union with God and secondly, the unifying aspects and common rules in human relations in community life were central. Union with God is based on the fact that in a soul God is living in its centre, where God is present in the Trinitarian way. The picture of God in ourselves is a mirror but to get to know God better is to recognize his/her presence in us. When the soul recognizes itself as a dwelling place of God, it knows itself as God knows him/herself. There is equality between God and the soul. To be a Christian means to participate in God in his Trinitarian being. The participation to God is a process of divinization that puts a person into transformation, change and renewal. The unitive aspect concludes also knowledge of opposites between experience of community and solitude as well as community and separateness. As a founder of monasteries St Teresa practiced theology of poverty. She renewed the monastic life founding a rule called discalced that stressed ascetic tendencies. Supporters of her work were after the difficulties in the beginning both society and churchly leaders. She wrote about the monasteries including in her description at times seriousness at times humor and irony. Her stories are said to be picaresque histories that contain stories of ordinary laymen and many unexpected occasions. She exercised a kind of Bakhtinian dialogue in her letters. St Teresa stressed the virtues like sacrifice, determination and courage in the monastic life. Most of what she taught of virtues is based on biblical spirituality but there are also psychological tendencies in her writings. The theological pedagogical advice is mixed with psychology, but she herself made no distinction between different aspects in her teaching. To understand St Teresa and her mysticism is to recognize that she mixes her personal religious experience and mysticism, which widens mysticism to religious experience in a new way, although this corresponds also the very definition of mysticism. St Teresa concentrated on mental-spiritual experiences and the aim of her mystical teaching was to produce a human mind well cured like a garden that has God as its gardener.

A vast amount of public services and goods are contracted through procurement auctions. Therefore it is very important to design these auctions in an optimal way. Typically, we are interested in two different objectives. The first objective is efficiency. Efficiency means that the contract is awarded to the bidder that values it the most, which in the procurement setting means the bidder that has the lowest cost of providing a service with a given quality. The second objective is to maximize public revenue. Maximizing public revenue means minimizing the costs of procurement. Both of these goals are important from the welfare point of view. In this thesis, I analyze field data from procurement auctions and show how empirical analysis can be used to help design the auctions to maximize public revenue. In particular, I concentrate on how competition, which means the number of bidders, should be taken into account in the design of auctions. In the first chapter, the main policy question is whether the auctioneer should spend resources to induce more competition. The information paradigm is essential in analyzing the effects of competition. We talk of a private values information paradigm when the bidders know their valuations exactly. In a common value information paradigm, the information about the value of the object is dispersed among the bidders. With private values more competition always increases the public revenue but with common values the effect of competition is uncertain. I study the effects of competition in the City of Helsinki bus transit market by conducting tests for common values. I also extend an existing test by allowing bidder asymmetry. The information paradigm seems to be that of common values. The bus companies that have garages close to the contracted routes are influenced more by the common value elements than those whose garages are further away. Therefore, attracting more bidders does not necessarily lower procurement costs, and thus the City should not implement costly policies to induce more competition. In the second chapter, I ask how the auctioneer can increase its revenue by changing contract characteristics like contract sizes and durations. I find that the City of Helsinki should shorten the contract duration in the bus transit auctions because that would decrease the importance of common value components and cheaply increase entry which now would have a more beneficial impact on the public revenue. Typically, cartels decrease the public revenue in a significant way. In the third chapter, I propose a new statistical method for detecting collusion and compare it with an existing test. I argue that my test is robust to unobserved heterogeneity unlike the existing test. I apply both methods to procurement auctions that contract snow removal in schools of Helsinki. According to these tests, the bidding behavior of two of the bidders seems consistent with a contract allocation scheme.

For the past twenty years, several indicator sets have been produced on international, national and regional levels. Most of the work has concentrated on the selection of the indicators and on collection of the pertinent data, but less attention has been given to the actual users and their needs. This dissertation focuses on the use of sustainable development indicator sets. The dissertation explores the reasons that have deterred the use of the indicators, discusses the role of sustainable development indicators in a policy-cycle and broadens the view of use by recognising three different types of use. The work presents two indicator development processes: The Finnish national sustainable development indicators and the socio-cultural indicators supporting the measurement of eco-efficiency in the Kymenlaakso Region. The sets are compared by using a framework created in this work to describe indicator process quality. It includes five principles supported by more specific criteria. The principles are high policy relevance, sound indicator quality, efficient participation, effective dissemination and long-term institutionalisation. The framework provided a way to identify the key obstacles for use. The two immediate problems with current indicator sets are that the users are unaware of them and the indicators are often unsuitable to their needs. The reasons for these major flaws are irrelevance of the indicators to the policy needs, technical shortcomings in the context and presentation, failure to engage the users in the development process, non-existent dissemination strategies and lack of institutionalisation to promote and update the indicators. The importance of the different obstacles differs among the users and use types. In addition to the indicator projects, materials used in the dissertation include 38 interviews of high-level policy-makers or civil servants close to them, statistics of the national indicator Internet-page downloads, citations of the national indicator publication, and the media coverage of both indicator sets. According to the results, the most likely use for a sustainable development indicator set by policy-makers is to learn about the concept. Very little evidence of direct use to support decision-making was available. Conceptual use is also common for other user groups, namely the media, civil servants, researchers, students and teachers. Decision-makers themselves consider the most obvious use for the indicators to be the promotion of their own views which is a form of legitimising use. The sustainable development indicators have different types of use in the policy cycle and most commonly expected instrumental use is not very likely or even desirable at all stages. Stages of persuading the public and the decision-makers about new problems as well as in formulating new policies employ legitimising use. Learning by conceptual use is also inherent to policy-making as people involved learn about the new situation. Instrumental use is most likely in policy formulation, implementation and evaluation. The dissertation is an article dissertation, including five papers that are published in scientific journals and an extensive introductory chapter that discusses and weaves together the papers.

Work capacity assessment meeting as a decision-making situation of a multi-professional team a study on interaction and patient participation Multi-professional working has become an increasingly popular method of work in social and health care. The introduction of the viewpoints of several professionals is seen as a way to enhance the openness and quality of decision-making. However, so far relatively few study results are available on the implementation of this method in actual operations. This study examines one work method, a work capacity assessment meeting, along with medical certificates B and their enclosures written by the doctor to the patient after a meeting. After the theoretical and methodological chapter, providing background information, the study describes the structure of the meeting and the medical certificate as a constructive factor. This is followed by a discussion on the manner of assessing the various domains of the patient s functional capacity and the decision-making based on the assessed factors. Next, the study moves on to examine the effect of patient involvements on the conclusions and decisions that professionals make at the meeting. In conclusion, the study looks into how the voices of the professionals and the customer are transferred to the medical certificate. The material of the study consists of 11 meetings recorded on video, of which eight are work capacity assessment meetings and three are rehabilitation examination meetings. The first type of meeting is attended by a patient and a number of professionals, while the latter is attended only by the professionals. All the patients, whose cases are discussed in the work capacity assessment meetings, have a musculoskeletal disorder, while the rehabilitation meetings are related to patients who all also have some additional problem. The study material also consists of seven medical certificates B, written after a work capacity assessment meeting. For the most part, the material has been collected by the conversation analysis method. Moreover, also discourse analysis and a rhetorical approach were used. By using conversation analysis, it is possible to study closely how interaction is built up at the meeting and to examine how the actors implement their institutional assessment tasks in a co-operation that takes its form turn by turn. The four main findings of the study are as follows: firstly, the meeting is structured to a great extent on the basis of the medical certificate form to various phases of the meeting and the headings of the certificate are seen as communicative affordances at the meeting, directed primarily to the professionals that have assessed the patient s work capacity with various tests. The medical certificate is the ethno-method of the doctor acting as the chairman of the meeting that functions in two directions: it constructs the meeting and constitutes the task of the professionals as they produce contents for it. Secondly, the study describes the ways that are used to assess the different domains of the patient s work capacity, how they are described at the meeting and how a decision is taken when the assessment information has been saturated in the opinion of the team. Thirdly, the study brings up ways, with which the patient can influence the conclusions and decisions made by the professionals at the meeting. The study showed that the patient can affect the preconditions of his or her own future and wellbeing. Fourthly, the study describes how the wealth of expressions at the meeting is transferred to the certificate as an argumentative micro-cosmos, where the patient is classified to be recommended for rehabilitation or disability pension. An important finding is also how objective and subjective information and the voices of actors at the meeting are transferred to the statement in a strategic and intentional manner, with an orientation to the decision that will be taken at the insurance institution. The study results can be utilized in the training of professionals and in developing the operations of organisations performing the assessment of the work capacity of people suffering from musculoskeletal disorders.

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.

This thesis consists of an introduction to a topic of optimal use of taxes and government expenditure and three chapters analysing these themes more in depth. Chapter 2 analyses to what extent a given amount of subsidies affects the labour supply of parents. Municipal supplement to the Finnish home care allowance provides exogenous variation to labour supply decision of a parent. This kind of subsidy that is tied to staying at home instead of working is found to have fairly large effect on labour supply decisions of parents. Chapter 3 studies theoretically when it is optimal to provide publicly private goods. In the set up of the model government sets income taxes optimally and provides a private good, if it is beneficial to do so. The analysis results in an optimal provision rule according to which the good should be provided when it lowers the participation threshold into labour force. Chapter 4 investigates what happened to prices and demand when hairdressers value added tax was cut in Finland from 22 per cent to 8 per cent. The pass-through to prices was about half of the full pass-through and no clear indication of increased demand for the services or better employment situation in the sector is found.

Aim: So far, most of the cognitive neuroscience studies investigating the development of brain activity in childhood have made comparisons between different age groups and ignored the individual stage of cognitive development. Given the wide variation in the rate of cognitive development, this study argues that chronological age alone cannot explain the developmental changes in brain activity. This study demonstrates how Piaget s theory and information on child s individual stage of development can complement the age-related evaluations of brain oscillatory activity. In addition, the relationship between cognitive development and working memory is investigated. Method: A total of 33 children (17 11-year-olds, 16 14-year-olds) participated in this study. The study consisted of behavioural tests and an EEG experiment. Behavioral tests included two Piagetian tasks (the Volume and Density task, the Pendulum task) and Raven s Standard Progressive Matrices task. During EEG experiment, subjects performed a modified version of the Sternberg s memory search paradigm which consisted of an auditorily presented memory set of 4 words and a probe word following these. The EEG data was analyzed using the event-related desynchronization / synchronization (ERD/ERS) method. The Pendulum task was used to assess the cognitive developmental stage of each subject and to form four groups based on age (11- or 14-year-olds) and cognitive developmental stage (concrete or formal operational stage). Group comparisons between these four groups were performed for the EEG data. Results and conclusions: Both age- and cognitive stage-related differences in brain oscillatory activity were found between the four groups. Importantly, age-related changes similar to those reported by previous studies were found also in this study, but these changes were modified by developmental stage. In addition, the results support a strong link between working memory and cognitive development by demonstrating differences in memory task related brain activity and cognitive developmental stages. Based on these findings it is suggested that in the future, comparisons of development of brain activity should not be based only on age but also on the individual cognitive developmental stage.

Microfinance institutions (MFIs) are constrained by double bottom-lines: meeting social obligations (the first bottom-line) and obtaining financial self-sufficiency (the second bottom-line). The proponents of the first bottom-line, however, are increasingly concerned that there is a trade-off between these two bottom-lines—i.e., getting hold of financial self-sufficiency may lead MFIs to drift away from their original social mission of serving the very poor, commonly known as mission drift in microfinance which is still a controversial issue. This study aims at addressing the concerns for mission drift in microfinance in a performance analysis framework. Chapter 1 deals with theoretical background, motivation and objectives of the topic. Then the study explores the validity of three major and related present-day concerns. Chapter 2 explores the impact of profitability on outreach-quality in MFIs, commonly known as mission drift, using a unique panel database that contains 4-9 years’ observations from 253 MFIs in 69 countries. Chapter 3 introduces factor analysis, a multivariate tool, in the process of analysing mission drift in microfinance and the exercise in this chapter demonstrates how the statistical tool of factor analysis can be utilised to examine this conjecture. In order to explore why some microfinance institutions (MFIs) perform better than others, Chapter 4 looks at factors which have an impact on several performance indicators of MFIs—profitability or sustainability, repayment status and cost indicators—based on quality-data on 353 institutions in 77 countries. The study also demonstrates whether such mission drift can be avoided while having self-sustainability. In Chapter 5 we examine the impact of capital and financing structure on the performance of microfinance institutions where estimations with instruments have been performed using a panel dataset of 782 MFIs in 92 countries for the period 2000-2007. Finally, Chapter 6 concludes the study by summarising the results from the previous chapters and suggesting some directions for future studies.

Topics in Spatial Econometrics — With Applications to House Prices Spatial effects in data occur when geographical closeness of observations influences the relation between the observations. When two points on a map are close to each other, the observed values on a variable at those points tend to be similar. The further away the two points are from each other, the less similar the observed values tend to be. Recent technical developments, geographical information systems (GIS) and global positioning systems (GPS) have brought about a renewed interest in spatial matters. For instance, it is possible to observe the exact location of an observation and combine it with other characteristics. Spatial econometrics integrates spatial aspects into econometric models and analysis. The thesis concentrates mainly on methodological issues, but the findings are illustrated by empirical studies on house price data. The thesis consists of an introductory chapter and four essays. The introductory chapter presents an overview of topics and problems in spatial econometrics. It discusses spatial effects, spatial weights matrices, especially k-nearest neighbours weights matrices, and various spatial econometric models, as well as estimation methods and inference. Further, the problem of omitted variables, a few computational and empirical aspects, the bootstrap procedure and the spatial J-test are presented. In addition, a discussion on hedonic house price models is included. In the first essay a comparison is made between spatial econometrics and time series analysis. By restricting the attention to unilateral spatial autoregressive processes, it is shown that a unilateral spatial autoregression, which enjoys similar properties as an autoregression with time series, can be defined. By an empirical study on house price data the second essay shows that it is possible to form coordinate-based, spatially autoregressive variables, which are at least to some extent able to replace the spatial structure in a spatial econometric model. In the third essay a strategy for specifying a k-nearest neighbours weights matrix by applying the spatial J-test is suggested, studied and demonstrated. In the final fourth essay the properties of the asymptotic spatial J-test are further examined. A simulation study shows that the spatial J-test can be used for distinguishing between general spatial models with different k-nearest neighbours weights matrices. A bootstrap spatial J-test is suggested to correct the size of the asymptotic test in small samples.
