In the 1990 s the companies utilizing and producing new information technology, especially so-called new media, were also expected to be forerunners in new forms of work and organization. Researchers anticipated that new, more creative forms of work and the changing content of working life were about to replace old industrial and standardized ways of working. However, research on actual companies in the IT sector revealed a situation where only minor changes to existing organizational forms were seen .Many of the independent companies faced great difficulties trying to survive the rapid changes in the products and production forms in the emerging field. Most of the research on the new media field has been conducted as surveys, and an understanding of the actual everyday work process has remained thin. My research is a longitudinal study of the early phases of one new media company in Finland. The study is an analysis of the challenges the company faced in a rapidly changing business field and the attempts to overcome these challenges. The two main analyses in the study focus on the developmental phases of the company and the disturbances in the production process. Based on these analyses, I study changes and learning at work using the methodological framework of developmental work research. Developmental work research is a Finnish variant of the cultural-historical activity theory applied to the study of learning and transformations at work. The data was gathered over a three-year period of ethnographic fieldwork. I documented the production processes and everyday life in the company as a participant observer. I interviewed key persons, video and audio-taped meetings, followed e-mail correspondence and collected various documents, such as agreements and memos. I developed a systematic method for analyzing the disturbances in the production process by combining the various data sources. The systematic analysis of the disturbances depicted a very complex and only partly managed production process. The production process had a long duration, and no single actor had an understanding of it as a whole. Most of the disturbances had to do with the customer relationships. The nature of the disturbances was latent; they were recognized but not addressed. In the particular production processes that I analyzed, the ending life span of a particular product, a CD-ROM, became obvious. This finding can be interpreted in relation to the developmental phase of the production and the transformation of the field as a whole. Based on the analysis of the developmental phases and the disturbances, I formulate a hypothesis of the contradictions and developmental potentials of the activity studied. The conclusions of the study challenge the existing understanding of how to conceptualize and study organizational learning in production work. Most theories of organizational learning do not address qualitative changes in production nor historical challenges of organizational learning itself. My study opens up a new horizon in understanding organizational learning in a rapidly changing field where a learning culture based on craft or mass production work is insufficient. There is a need for anticipatory and proactive organizational learning. Proactive learning is needed to anticipate the changes in production type, and the life cycles of products.

Various reasons, such as ethical issues in maintaining blood resources, growing costs, and strict requirements for safe blood, have increased the pressure for efficient use of resources in blood banking. The competence of blood establishments can be characterized by their ability to predict the volume of blood collection to be able to provide cellular blood components in a timely manner as dictated by hospital demand. The stochastically varying clinical need for platelets (PLTs) sets a specific challenge for balancing supply with requests. Labour has been proven a primary cost-driver and should be managed efficiently. International comparisons of blood banking could recognize inefficiencies and allow reallocation of resources. Seventeen blood centres from 10 countries in continental Europe, Great Britain, and Scandinavia participated in this study. The centres were national institutes (5), parts of the local Red Cross organisation (5), or integrated into university hospitals (7). This study focused on the departments of blood component preparation of the centres. The data were obtained retrospectively by computerized questionnaires completed via Internet for the years 2000-2002. The data were used in four original articles (numbered I through IV) that form the basis of this thesis. Non-parametric data envelopment analysis (DEA, II-IV) was applied to evaluate and compare the relative efficiency of blood component preparation. Several models were created using different input and output combinations. The focus of comparisons was on the technical efficiency (II-III) and the labour efficiency (I, IV). An empirical cost model was tested to evaluate the cost efficiency (IV). Purchasing power parities (PPP, IV) were used to adjust the costs of the working hours and to make the costs comparable among countries. The total annual number of whole blood (WB) collections varied from 8,880 to 290,352 in the centres (I). Significant variation was also observed in the annual volume of produced red blood cells (RBCs) and PLTs. The annual number of PLTs produced by any method varied from 2,788 to 104,622 units. In 2002, 73% of all PLTs were produced by the buffy coat (BC) method, 23% by aphaeresis and 4% by the platelet-rich plasma (PRP) method. The annual discard rate of PLTs varied from 3.9% to 31%. The mean discard rate (13%) remained in the same range throughout the study period and demonstrated similar levels and variation in 2003-2004 according to a specific follow-up question (14%, range 3.8%-24%). The annual PLT discard rates were, to some extent, associated with production volumes. The mean RBC discard rate was 4.5% (range 0.2%-7.7%). Technical efficiency showed marked variation (median 60%, range 41%-100%) among the centres (II). Compared to the efficient departments, the inefficient departments used excess labour resources (and probably) production equipment to produce RBCs and PLTs. Technical efficiency tended to be higher when the (theoretical) proportion of lost WB collections (total RBC+PLT loss) from all collections was low (III). The labour efficiency varied remarkably, from 25% to 100% (median 47%) when working hours were the only input (IV). Using the estimated total costs as the input (cost efficiency) revealed an even greater variation (13%-100%) and overall lower efficiency level compared to labour only as the input. In cost efficiency only, the savings potential (observed inefficiency) was more than 50% in 10 departments, whereas labour and cost savings potentials were both more than 50% in six departments. The association between department size and efficiency (scale efficiency) could not be verified statistically in the small sample. In conclusion, international evaluation of the technical efficiency in component preparation departments revealed remarkable variation. A suboptimal combination of manpower and production output levels was the major cause of inefficiency, and the efficiency did not directly relate to production volume. Evaluation of the reasons for discarding components may offer a novel approach to study efficiency. DEA was proven applicable in analyses including various factors as inputs and outputs. This study suggests that analytical models can be developed to serve as indicators of technical efficiency and promote improvements in the management of limited resources. The work also demonstrates the importance of integrating efficiency analysis into international comparisons of blood banking.

Tutkielmassa arvioidaan taajuushuutokauppojen taloudellista tehokkuutta. Tutkielmassa tarkastellaan erityisesti huutokaupan allokatiivista tehokkuutta ja sen toteutumista kahdessa huutokauppatapauksessa. Työn metodeina on historiallinen tarkastelu taajuushuutokauppojen kehityshistoriasta, toimialatarkastelu teletoimialasta, peliteoreettinen analyysi monen kohteen huutokaupan taloudellisesta tehokkuudesta sekä huutokaupassa asetettujen huutojen suuruuksien sekä määrien analysointi Suomen ja Ruotsin 2,6 GHz:n huutokauppojen osalta. Historiallisen tarkastelun tuloksena esitetään, että huutokaupat ovat taloudellisesti tehokkaampi menetelmä kuin muut taajuusjakomenetelmät: arpajaiset, hallinnollinen arviointi tai ns. ”first come first serve” –menetelmä. Matemaattisen analyysin avulla määritellään tarkasti huutokaupan tehokkuus monen kohteen huutokaupassa ja miten huutokauppamekanismilla voidaan ohjata huutokauppa tehokkaaseen lopputulemaan. 2,6 GHz:n Suomen ja Ruotsin huutokauppojen osalta johtopäätöksinä esitetään, että Ruotsin huutokaupassa todennäköisesti saavutettiin tehokas lopputulema. Suomen huutokaupan osalta esitetään, että huutokaupan taloudelliset mekanismit eivät välttämättä ohjanneet huutokauppaa tehokkaaseen lopputulemaan. Suurimpana syynä Suomen huutokaupan mahdollisesti tehottomaan lopputulemaan voitaneen pitää huutokaupassa ilmennyttä, osittain mekanismista johtunutta, vähäistä kysyntää.

Työn tavoitteena on tutkia nautatilojen lannan käsittelytapojen taloudellista kannattavuutta. Tutkimuksessa verrataan lietelannan vaihtoehtoisia käsittelytapoja, joita ovat (a) lietteen levittäminen peltoon ilman esikäsittelyä, (b) lietelannan jakeistaminen typpipitoiseen nestejakeeseen ja fosforipitoiseen kuivajakeeseen sekä (c) lannan hyödyntäminen biokaasun tuotannossa. Aineistona tutkimuksessa käytetään aiempia tutkimustuloksia sekä Vieremällä sijaitsevien nautatilojen (21 kpl) tietoja. Menetelmänä käytetään lineaarista ohjelmointia ja malli ratkaistaan GAMS -ohjelmaa käyttämällä. Teoriana tutkimuksessa on tuotanto- ja kustannusteoria. Tutkimuksessa tarkastellaan kuinka eläintiheys, peltolohkorakenne sekä kustannusten muutokset vaikuttavat lannankäsittelyyn. Tutkimuksessa havaitaan, että kun kaikkea lietettä ei voida levittää tilan hallinnassa oleville pelloille, on lietteen jakeistaminen kannattavaa, jos jakeistuskustannus ei ylitä 1,2 €/m3. Sijoituslevityksen havaitaan olevan hajalevitystä kannattavampaa, paitsi typen hinnan ollessa hyvin alhainen hajalevitys on kannattavampi vaihtoehto. Korkea typpikustannus ja lietteen jakeistuskustannus tekevät biokaasun tuotannosta kannattavan vaihtoehdon, jos biokaasulaitos sijaitsee hyvin lähellä tilaa. Lietteen jakeistaminen on kannattavaa alueilla, joilla lannanlevityspinta-alasta on niukkuutta. Jakeistettavaa lietettä on kuitenkin oltava vähintään 20 000 m3/a, jotta jakeistuslaitteen hankkiminen on kannattavaa. Biokaasun tuotannon ei katsota olevan tällä hetkellä kannattava lannan käsittelyvaihtoehto, koska laitoksen olisi saatava tarvittava raaka-ainemäärä kaikissa tapauksissa alle kahden kilometrin säteeltä, eikä tämän katsota onnistuvan. Vieremän tiloista ainoastaan yksi tila sijaitsee riittävän lähellä suunniteltua laitoksen sijaintipaikkaa.

The objectives of this study were to make a detailed and systematic empirical analysis of microfinance borrowers and non-borrowers in Bangladesh and also examine how efficiency measures are influenced by the access to agricultural microfinance. In the empirical analysis, this study used both parametric and non-parametric frontier approaches to investigate differences in efficiency estimates between microfinance borrowers and non-borrowers. This thesis, based on five articles, applied data obtained from a survey of 360 farm households from north-central and north-western regions in Bangladesh. The methods used in this investigation involve stochastic frontier (SFA) and data envelopment analysis (DEA) in addition to sample selectivity and limited dependent variable models. In article I, technical efficiency (TE) estimation and identification of its determinants were performed by applying an extended Cobb-Douglas stochastic frontier production function. The results show that farm households had a mean TE of 83% with lower TE scores for the non-borrowers of agricultural microfinance. Addressing institutional policies regarding the consolidation of individual plots into farm units, ensuring access to microfinance, extension education for the farmers with longer farming experience are suggested to improve the TE of the farmers. In article II, the objective was to assess the effects of access to microfinance on household production and cost efficiency (CE) and to determine the efficiency differences between the microfinance participating and non-participating farms. In addition, a non-discretionary DEA model was applied to capture directly the influence of microfinance on farm households production and CE. The results suggested that under both pooled DEA models and non-discretionary DEA models, farmers with access to microfinance were significantly more efficient than their non-borrowing counterparts. Results also revealed that land fragmentation, family size, household wealth, on farm-training and off farm income share are the main determinants of inefficiency after effectively correcting for sample selection bias. In article III, the TE of traditional variety (TV) and high-yielding-variety (HYV) rice producers were estimated in addition to investigating the determinants of adoption rate of HYV rice. Furthermore, the role of TE as a potential determinant to explain the differences of adoption rate of HYV rice among the farmers was assessed. The results indicated that in spite of its much higher yield potential, HYV rice production was associated with lower TE and had a greater variability in yield. It was also found that TE had a significant positive influence on the adoption rates of HYV rice. In article IV, we estimated profit efficiency (PE) and profit-loss between microfinance borrowers and non-borrowers by a sample selection framework, which provided a general framework for testing and taking into account the sample selection in the stochastic (profit) frontier function analysis. After effectively correcting for selectivity bias, the mean PE of the microfinance borrowers and non-borrowers were estimated at 68% and 52% respectively. This suggested that a considerable share of profits were lost due to profit inefficiencies in rice production. The results also demonstrated that access to microfinance contributes significantly to increasing PE and reducing profit-loss per hectare land. In article V, the effects of credit constraints on TE, allocative efficiency (AE) and CE were assessed while adequately controlling for sample selection bias. The confidence intervals were determined by the bootstrap method for both samples. The results indicated that differences in average efficiency scores of credit constrained and unconstrained farms were not statistically significant although the average efficiencies tended to be higher in the group of unconstrained farms. After effectively correcting for selectivity bias, household experience, number of dependents, off-farm income, farm size, access to on farm training and yearly savings were found to be the main determinants of inefficiencies. In general, the results of the study revealed the existence substantial technical, allocative, economic inefficiencies and also considerable profit inefficiencies. The results of the study suggested the need to streamline agricultural microfinance by the microfinance institutions (MFIs), donor agencies and government at all tiers. Moreover, formulating policies that ensure greater access to agricultural microfinance to the smallholder farmers on a sustainable basis in the study areas to enhance productivity and efficiency has been recommended. Key Words: Technical, allocative, economic efficiency, DEA, Non-discretionary DEA, selection bias, bootstrapping, microfinance, Bangladesh.

Effective processing of powdered particles can facilitate powder handling and result in better drug product performance, which is of great importance in the pharmaceutical industry where the majority of active pharmaceutical ingredients (APIs) are delivered as solid dosage forms. The purpose of this work was to develop a new ultrasound-assisted method for particle surface modification and thin-coating of pharmaceutical powders. The ultrasound was used to produce an aqueous mist with or without a coating agent. By using the proposed technique, it was possible to decrease the interparticular interactions and improve rheological properties of poorly-flowing water-soluble powders by aqueous smoothing of the rough surfaces of irregular particles. In turn, hydrophilic polymer thin-coating of a hydrophobic substance diminished the triboelectrostatic charge transfer and improved the flowability of highly cohesive powder. To determine the coating efficiency of the technique, the bioactive molecule β-galactosidase was layered onto the surface of powdered lactose particles. Enzyme-treated materials were analysed by assaying the quantity of the reaction product generated during enzymatic cleavage of the milk sugar. A near-linear increase in the thickness of the drug layer was obtained during progressive treatment. Using the enzyme coating procedure, it was confirmed that the ultrasound-assisted technique is suitable for processing labile protein materials. In addition, this pre-treatment of milk sugar could be used to improve utilization of lactose-containing formulations for populations suffering from severe lactose intolerance. Furthermore, the applicability of the thin-coating technique for improving homogeneity of low-dose solid dosage forms was shown. The carrier particles coated with API gave rise to uniform distribution of the drug within the powder. The mixture remained homogeneous during further tabletting, whereas the reference physical powder mixture was subject to segregation. In conclusion, ultrasound-assisted surface engineering of pharmaceutical powders can be effective technology for improving formulation and performance of solid dosage forms such as dry powder inhalers (DPI) and direct compression products.

Väitöskirja analysoi espanjan kielen dekonstruktioita ruumiin metaforista ja troopeista koostuvassa aineistossa chileläisen kirjailijan Diamela Eltitin (1949 -) neljässä romaanissa: Lumpérica (1983), Vaca sagrada (1991), El infarto del alma (1994) ja Los trabajadores de la muerte (1998). Näkökulma on kielen muutoksessa Eltitin proosassa 1980- ja 1990-luvuilla alkaen kokeellisesta huippuvaiheesta 1983, jolloin hän julkaisi esikoisromaaninsa Lumpérica. Tutkimus korostaa Eltitin romaanien historiallista arvoa, kirjallisuuden tapaa murtaa kielen rakenteita ja sitä miten tämä murros kytkeytyy taideteoreettiseen muutokseen kulttuuridiskursseissa. Tutkimus tarkastelee Eltitin kehityskaarta kenraali Augusto Pinochetin sotilasvallankaappauksesta 1973 halki sotilashallituksen kauden (1973-1990) aina kansalaisyhteiskunnan vahvistumiseen ja vuoteen 1998. Tutkimus analysoi ruumiin troopeista ja metaforista koostuvaa tutkimusaineistoa lingvistiikan, kirjallisuustieteen, historian ja sukupuolen tutkimuksen monitieteisessä viitekehyksessä. Sen vuoksi väitöskirja liittyy espanjalaisen filologian, yleisen kirjallisuustieteen, Latinalaisen Amerikan tutkimuksen ja naistutkimuksen oppiaineisiin. Kolme tärkeintä oppiteoreettista runkoa ovat lingvistinen strukturalismi, dekonstruktio ja feministiset kirjallisuusteoriat. Dekonstruktiivinen lähestymistapa tekstiin korostaa kielen merkityksen muodostumisen filosofista perustaa. Se pyrkii selvittämään, miten merkitys muodostuu kirjoittajan, tekstin ja lukijan välillä. Tekstikritiikki koostuu semanttisesta ja dekonstruktiivisesta tekstianalyysistä, jonka metodologisen mallin perusta on tanskalaisen kielitieteilijän Louis Hjelmslevin (1899-1965) kielitieteellinen malli. Väitös ei käytä mallia suoraan, vaan soveltaa sitä kaunokirjallisuuden tutkimukseen. Oppiteoreettisen viitekehyksen osalta tutkimus sijoittuu strukturalismin ja poststrukturalismin murrokseen. Tutkimus korostaa Eltitin radikaalia muotokieltä ja teatraalisuutta, hänen kielensä visuaalisuutta ja ruumiin metaforien eroottista jännitettä, mikä ilmenee mm. falloksen metaforaksi tulkitun hehkuvan valon kuvissa romaanissa Lumpérica. Vanhat kreikkalaiset myytit Éros ja Thánatos kasvavat esille länsimaisen taidehistorian perinteestä ja kontekstualisoituvat uusiksi kielikuviksi Chilen kirjallisessa maaperässä. Ne muodostavat Eltitin taiteellisen tuotannon pysyvän aihepiirin ja luovat teoksiin synkkää ja karua virettä sekä tummia ja eroottisia sävyjä. Tutkimus osoittaa, että Eltit dekonstruoi kieltä, mutta dekonstruktiot eivät ole jatkuvia eivätkä samanlaisia kaikissa romaaneissa. Kielellisten dekonstruktioiden variaatio on laaja eikä Eltit murra kielen syntaktisia ja morfologisia rakenteita kaikissa teksteissään. Tutkimuksen perusteella väitän, että Eltitin kirjoituksesta puhuttaessa useat tutkijat käyttävät epämääräisesti dekonstruktio-termiä. Useiden tutkijoiden toteamus dekonstruktiosta Diamela Eltitin kirjallisessa tuotannossa pysyvänä piirteenä on epätäsmällinen. Sen sijaan dekonstruktiivinen kirjoitus tarkoittaa Eltitillä laajasti vaihtelevaa lähestymistapaa kieleen, mikä ilmenee kehityslinjana hänen tuotannossaan ja eri tavoin jokaisessa teoksessa.

Joseph Brodsky, one of the most influential Russian intellectuals of the late Soviet period, was born in Leningrad in 1940, emigrated to the United States in 1972, received the Nobel Prize for Literature in 1987, and died in New York City in 1996. Brodsky was one of the leading public figures of Soviet emigration in the Cold War period, and his role as a model for the constructing of Russian cultural identities in the last years of the Soviet Union was, and still is, extremely important. One of Joseph Brodsky’s great contributions to Russian culture of the latter half of the twentieth century is the wide geographical scope of his poetic and prose works. Brodsky was not a travel writer, but he was a traveling writer who wrote a considerable number of poems and essays which relate to his trips and travels in the Soviet empire and outside it. Travel writing offered for Brodsky a discursive space for negotiating his own transculturation, while it also offered him a discursive space for making powerful statements about displacement, culture, history and geography, time and space—all major themes of his poetry. In this study of Joseph Brodsky’s travel writing I focus on his travel texts in poetry and prose, which relate to his post-1972 trips to Mexico, Brazil, Turkey, and Venice. Questions of empire, tourism, and nostalgia are foregrounded in one way or another in Brodsky’s travel writing performed in emigration. I explore these concepts through the study of tropes, strategies of identity construction, and the politics of representation. The theoretical premises of my work draw on the literary and cultural criticism which has evolved around the study of travel and travel writing in recent years. These approaches have gained much from the scholarly experience provided by postcolonial critique. Shifting the focus away from the concept of exile, the traditional framework for scholarly discussions of Brodsky’s works, I propose to review Brodsky’s travel poetry and prose as a response not only to his exilic condition but to the postmodern and postcolonial landscape, which initially shaped the writing of these texts. Discussing Brodsky’s travel writing in this context offers previously unexplored perspectives for analyzing the geopolitical, philosophical, and linguistic premises of his poetic imagination. By situating Brodsky’s travel writing in the geopolitical landscape of postcolonial postmodernity, I attempt to show how Brodsky’s engagement with his contemporary cultural practices in the West was incorporated into his Russian-language travel poetry and prose and how this engagement thus contributed to these texts’ status as exceptional and unique literary events within late Soviet Russian cultural practices.

Literary tale of A.M. Remizov (1900’s – 1920’s) The thesis is devoted to a detailed historical-literary description of a tale as a genre tradition in the creative work of Alexei Mikhailovich Remizov (1877-1957), one of the major Russian prose writers of the 20’s century. This very approach allows to specify the place and functional meaning of this genre in literary practice of the writer and to appeal to one of the key problems of the 20-21 century literature history – a specific of modernistic literature composition principle and a role of montage techniques in its formation. Remizov was working on tales during his whole life, though the most productive years of folklore studies fell to 1900’s – 1910’s. During this period he intensively studied folklore materials, narrated several hundreds of folk tales and in 1900’s – 1920’s published eight tale collections which played a significant role in the formation of stylistic and compositional principles of his prose of the 1910’s – 1920’s, especially montage techniques, which in its turn influenced the development of the narrative forms in the Russian post-revolutionary literature. At the same time a tale has specified not only poetics but also problematics of Remizov’s creative work, as when choosing folklore sources the writer always alluded to modern themes and relevant intellectual trends. The current research work, based on various archive materials and a wide spectrum of modern historical-literary data, complies four chapters with a consistent description of creation history, publication and critics’ reviews of Remizov’s tale collections and single tales contributing to his creative evolution characteristic. Furthermore, the work refers to composition and subject of the particular collections. On the whole it enables to follow up genre dynamics. The first chapter of the work is devoted to Posolon’ (Sunwise), the earliest tale collection of Remizov. The main feature of the collection is that its composition is oriented on the agrarian calendar and the subject – on the system of mythological views reflected in the Russian folklore. This very collection to a large extent corresponds to the writer’s views on the myth represented in Pis’mo v redaktsiyu (Letter to the Editor). The history of this manifesto appearing is analyzed in the second chapter. The incident which caused its forthcoming contributed to ‘legitimization’ of Remizov’s narrations as a relevant genre of modern literature and to upgrading the writer in professional hierarchy. The third chapter analyzes Remizov’s collections of 1900’s – early 1920’s, a result of Remizov’s scrupulous work with a specific tale material. He is acting here as a tale repertory researcher and in some cases as a collector as well. The means of such collections’ topical organization is not the myth but the hero of the tale. According to this principle single pieces are grouped into cycles, which then form complicated montage constructs. Texts themselves can be viewed as a sort of hyper-quotations, as they in fact entirely coincide with their original sources. Besides, collections usually have their own ideal patterns. In the fourth chapter a connection of Remizov’s creative work with folk fun culture and a tradition of the folklore noel story is being demonstrated on Zavetnyie skazy (Secret Tales) material. A consistent collections’ history creation analysis convinces us that the tale was a sort of laboratory in which main writer’s prose methods were being worked out.

This dissertation analyzes the interrelationship between death, the conditions of (wo)man s social being, and the notion of value as it emerges in the fiction of the American novelist Thomas Pynchon (1937 ). Pynchon s present work includes six novels V. (1963), The Crying of Lot 49 (1966), Gravity s Rainbow (1973), Vineland (1990), Mason & Dixon (1997), Against the Day (2006) and several short stories. Death constitues a central thematic in Pynchon s work, and it emerges through recurrent questions of mortality, suicide, mass destruction, sacrifice, afterlife, entropy, the relationship between the animate and the inanimate, and the limits of representation. In Pynchon, death is never a mere biological given (or event); it is always determined within a certain historical, cultural, and ideological context. Throughout his work, Pynchon questions the strict ontological separation of life and death by showing the relationship between this separation and social power. Conceptual divisions also reflect the relationship between society and its others, and death becomes that through which lines of social demarcation are articulated. Determined as a conceptual and social "other side", death in Pynchon forms a challenge to modern culture, and makes an unexpected return: the dead return to haunt the living, the inanimate and the animate fuse, and technoscientific attempts at overcoming and controlling death result in its re-emergence in mass destruction and ecological damage. The questioning of the ontological line also affects the structuration of Pynchon's prose, where the recurrent narrated and narrative desire to reach the limits of representation is openly associated with death. Textualized, death appears in Pynchon's writing as a sudden rupture within the textual functioning, when the "other side", that is, the bare materiality of the signifier is foregrounded. In this study, Pynchon s cultural criticism and his poetics come together, and I analyze the subversive role of death in his fiction through Jean Baudrillard s genealogy of the modern notion of death from L échange symbolique et la mort (1976). Baudrillard sees an intrinsic bond between the social repression of death in modernity and the emergence of modern political economy, and in his analysis economy and language appear as parallel systems for generating value (exchange value/ sign-value). For Baudrillard, the modern notion of death as negativity in relation to the positivity of life, and the fact that death cannot be given a proper meaning, betray an antagonistic relation between death and the notion of value. As a mode of negativity (that is, non-value), death becomes a moment of rupture in relation to value-based thinking in short, rationalism. Through this rupture emerges a form of thinking Baudrillard labels the symbolic, characterized by ambivalence and the subversion of conceptual opposites.

The study shows that the reading paradigm derived from codes Roland Barthes presented in his S/Z exposes the postmodernic nature of Saul Bellow s Herzog (1964), and embodies in which way the novel is organized as a radical rewriting of modernism and its ideology. I explore how solid, compact and modernistic subject breaks down at every level of Herzog s narration. I actually argue that the heteroglossic novel is representative of an early American postmodern movement in literaure, and it should by no means be dissected narrowly as a realistic or naturalistic novel at all. The intertextual code verifies that the interpretation of Herzog remains inadequate if one doesn t take account of the novel s significant intertextual references to other texts. In fact, even the mind of Moses Herzog, the protagonist of the novel, is a mosaic of citations. It emerges from the dissertation that the figure of Don Quixote follows Moses Herzog as an ambiguous shadow while the professor of history struggles with his anxiety and anguish, and travels in a mentally confused state around the U.S. for five days in the early 1960s, encountering the impending atmosphere of transition as the country is on the threshold of a significant cultural and social change. There is a strong necessity for updated interpretation of Herzog partly because its centrality to Bellow s own career as a writer but mainly because it has been previously read trough modernistic lenses. I shall try to proof in my study that American Jewish Saul Bellow s (1915 2005) Herzog escapes any kind of simple, elemental or essentialistic construction or reading and in real terms it doesn t offer any comprehensive, total or coherent solution or system for those philosophical doctrines it criticizes and makes fun of. The philosophical, conceptual and cultural substance of Herzog does not constitute an independent or autonomous theoretical tract which would have a life of its own. Altough the novel reflects the continuity of Bellow s writing it is clearly some kind of conscious or unconscious experiment during his long career as a writer. He hasn t been so radical before or since the publication of Herzog. It is unarguably his most postmodern novel.The reading paradigm based on specific codes demonstrates how deep into the basic questions of his personal life and existence itself he must dive in oder to find his many ways towards authentic or primordial self in fragmented and shattered world which is constanly rewritten and which makes human being a tourist of his own life. In that ongoing process the protagonist has to accept the ultimate plurality of his mind and self. He must confront that the modernistic definition of identity as a solid, monolithic and stable entity has broken down into different, inconsistent and even contradictory possibilities of identification. Moses Herzog embodies obviously Stuart Hall s description of the postmodern self his identity has turn into a movable feast.

Books Paths to Readers describes the history of the origins and consolidation of modern and open book stores in Finland 1740 1860. The thesis approaches the book trade as a part of a print culture. Instead of literary studies choice to concentrate on texts and writers, book history seeks to describe the print culture of a society and how the literary activities and societies interconnect. For book historians, printed works are creations of various individuals and groups: writers, printers, editors, book sellers, censors, critics and finally, readers. They all take part in the creation, delivery and interpretation of printed works. The study reveals the ways selling and distributing books have influenced the printed works and the literary and print culture. The research period 1740 1860 covers the so-called second revolution of the book, or the modernisation of the print culture. The thesis describes the history of 60 book stores and their 96 owners. The study concentrates on three themes: firstly, how the particular book trade network became a central institution for printed works distribution, secondly what were the relations between cosmopolitan European book markets and the national cultural sphere, and thirdly how book stores functioned as cultural institutions and business enterprises. Book stores that have a varied assortment and are targeted to all readers became the main institution for book trade in Finland during 1740 1860. It happened because of three features. First, the book binders monopoly on selling bound copies in Sweden was abolished in 1740s. As a consequence entrepreneurs could concentrate solely to trade activities and offer copies from various publishers at their stores. Secondly the common business model of bartering was replaced by selling copies for cash, first in the German book trade centre Leipzig in 1770s. The change intensified book markets activities and Finnish book stores foreign connections. Thirdly, after Finland was annexed to the Russian empire in 1809, the Grand duchy s administration steered foreign book trade to book stores (because of censorship demands). Up to 1830 s book stores were available only in Helsinki and Turku. During next ten years book stores opened in six regional centres. The early entrepreneurs ran usually vertical businesses consisting of printing, publishing and distribution activities. This strategy lowered costs, eased the delivery of printed works and helped to create elaborated centres for all book activities. These book stores main clientele consisted of the Swedish speaking gentry. During late 1840s various opinion leaders called for the development of a national Finnish print culture, and also book stores. As a result, during the five years before the beginning of the Crimean war (1853 1856) book stores were opened in almost all Finnish towns: at the beginning of the war 36 book stores operated in 21 towns. The later book sellers, mainly functioning in small towns among Finnish speaking people, settled usually strictly for selling activities. Book stores received most of their revenues from selling foreign titles. Swedish, German, French and Belgian (pirate editions of popular French novels) books were widely available for the multilingual gentry. Foreign titles and copies brought in most of the revenues. Censorship inspections or unfavourable custom fees would not limit the imports. Even if the local Finnish print production steadily rose, many copies, even titles, were never delivered via book stores. Only during the 1840 s and 1850 s the most advanced publishers would concentrate on creating publishing programmes and delivering their titles via book stores. Book sellers regulated commissions were small. They got even smaller because of large amounts of unsold copies, various and usual misunderstandings of consignments and accounts or plain accidents that destroyed shipments and warehouses. Also, the cultural aim of a creating large and assortments and the tendency of short selling periods demanded professional entrepreneurship, which many small town book sellers however lacked. In the midst of troublesome business efforts, co-operation and mutual concern of the book market s entrepreneurs were the key elements of the trade, although on local level book sellers would compete, sometimes even ferociously. The difficult circumstances (new censorship decree of 1850, Crimean war) and lack of entrepreneurship, experience and customers meant that half of the book stores opened in 1845 1860 was shut in less than five years. In 1858 the few leading publishers established The Finnish Book Publishers Association. Its first task was to create new business rules and manners for the book trade. The association s activities began to professionalise the whole network, but at the same time the earlier independence of regional publishing and selling enterprises diminished greatly. The consolidation of modern and open book store network in Finland is a history of a slow and complex development without clear signs of a beginning or an end. The ideal book store model was rarely accomplished in its all features. Nevertheless, book stores became the norm of the book trade. They managed to offer larger selections, reached larger clienteles and maintained constant activity better than any other book distribution model. In essential, the book stores methods have not changed up to present times.

Pro gradu -tutkielmassani paneudun yhden suomalaisen populaarimusiikin toimijan elämään, uraan, tuotantoon sekä hänen käsityksiinsä musiikista ja musiikintekemisestä. Tutkimukseni on suomalaisen populaarimusiikin historian perustutkimusta Sakari Kukon henkilöhistorian kautta. Tutkimuskysymyksiäni ovat: 1. Kuinka Sakari Kukosta tuli muusikko ja musiikintekijä? 2. Minkälainen on ja on ollut hänen tapansa toimia? Vastaan edellisiin kysymyksiin, mutta sijoitan vastaukset myös ajallisesti suomalaiseen musiikki- ja yhteiskuntakontekstiin. Ongelmanasettelu tähtää siihen, että selvitän sekä Kukon omat sisäiset motiivit ja päämäärät muusikkona ja musiikintekijänä että hänen ympäristönsä tarjoamat virikkeet ja vaikutteet. Ongelman ratkaisemiseksi kartoitan hänen elämänvaiheensa lapsuudesta tähän päivään, ympäristöt, joissa hän on kulloinkin toiminut sekä ne yhteiskunnalliset tilanteet, joihin hänen ja hänen ympäristönsä toiminta on sijoittunut. Tutkimus sijoittuu vuosien 1953 ja 2003 väliselle ajalle. Kuvailen Kukon tuotantoa levy levyltä edeten kronologisesti vuosikymmenittäin. Lisäksi kokoan tuotannon yhteen ja etsin hänen säveltämästään, sovittamastaan ja esittämästään musiikista muutamia erityisen vahvoja elementtejä. Tuloksena esittelen kahdeksan kategoriaa, joista jokainen on yhdistettävissä hänen elämänvaiheisiinsa ja asetettavissa vuorovaikutukseen lähiympäristön kanssa. Tutkielmassani käytän apuna mikrohistoriallista tutkimusotetta, joka sopii mainiosti työni toteuttamiseen. Tutkimusaineisto on hyvin laaja ja monipuolinen, ja olen poiminut tietoja muun muassa lehtiartikkeleista, arkistoista, levyjen kansista, festivaaliesitteistä ja kirjallisuudesta; kaikista ei löydy edes mainintaa päivästä, vuodesta tai kirjoittajasta. Tärkein aineistoni on kuitenkin muistinvarainen tieto eli Kukon haastattelumateriaali. Mikrohistorialliseen tutkimusotteeseen nojaten olen päässyt Kukon henkilöhistorian kautta käsiksi hieman yleisemmänkin tason asioihin ja ilmiöihin. Olen selvittänyt muun muassa Kajaani Big Bandin vaiheita 1950-luvulta 1970-luvulle sekä suomalaisen pop/jazz -koulutuksen kehitystä erilaisista musiikkileireistä Sibelius-Akatemian oppiaineeksi samalla, kun olen selvittänyt Kukon kehitystä muusikoksi. Lisäksi olen esitellyt esimerkiksi studiomuusikkoutta 1970-luvun Suomessa sekä senegalilaisen musiikkielämän piirteitä 1970- ja 1980-lukujen taitteessa. Mikrohistorioitsija Carlo Ginzburgin johtolanka-ajatusta mukaillen olen koonnut pienistä tiedon palasista, johtolangoista kokonaiskertomuksen. Avainsanat: Sakari Kukko, Piirpauke, suomalainen populaarimusiikki, jazz, mikrohistoria, henkilöhistoria

Tutkimuksessani olen keskittynyt tarkastelemaan säveltäjä Jukka Ruohomäen (s.1947) 1970-luvun sävellystuotantoa ja teosten tyylipiirteitä sekä Ruohomäen toimintaa elektroakustisen musiikin parissa. Ruohomäen 1970-luvun teokset kuuluvat elektroakustisen nauhamusiikin lajiin. Aiempaa tutkimusta hänen musiikistaan ei ole tehty. Tutkimuksen kohteen tarkastelua varten työssä luodaan kuva elektroakustisen musiikin historian, kulttuurin ja analyysin kehitykseen sekä elektroakustisen musiikin terminologiaan ja työtapoihin. Elektroakustisen musiikin historiallista kehitystä seurataan 1800-luvulta 1960- ja 1970-lukujen taitteeseen asti, jotta voidaan ymmärtää, mihin kulttuurihistorialliseen kontekstiin Ruohomäen ensimmäisen sävellyskauden (1970–1978) tuotanto on syntynyt. Historiallisesta näkökulmasta tutkimus on kartoittavaa perustutkimusta. Elektroakustisen musiikin analyysimenetelmiä esittelevässä osassa esitellään ne keskeiset menetelmät, joita tässä työssä käytetään Ruohomäen tuotannon analysointiin. Analyysin pääpaino on teosten äänimateriaalien ja rakenteen tarkastelussa. Tähän tarkasteluun valittuja analyysimenetelmiä ovat Simon Emmersonin elektroakustisten teosten jaottelu äänimateriaalien narratiivisuuden ja syntaktisten piirteiden suhteen, Denis Smalleyn spektromorfologia ja Robert Coganin musiikin kuvaamiseen esittelemä sonogrammikuvaaja. Ruohomäen 1970-luvun teosten esittelyn lisäksi tarkemman analyysin kohteeksi on valittu sävellys Pisces (1975–76). Teosesittelyjen pohjalta muodostetaan kuva Ruohomäen ensimmäisen sävellyskauden vaikutteista ja sävellystyylin muuttumisesta. Ruohomäki painottaa sävellysprosessissa kuuntelun merkitystä ja hänen teoksensa syntyvät pikemminkin vuorovaikutuksessa äänimateriaalin ja sävellysteknologian kanssa kuin tarkan etukäteissuunnitelman ohjaamina. Varhaisten teosten populaarimusiikkivaikutteista Ruohomäen musiikki kehittyi 1970-luvulla kohti puhtaampaa konkreettisen musiikin traditiota. Minimalistiset ja stokastisen musiikin ideat ovat kuultavissa kaikissa ensimmäisen sävellyskauden teoksissa. Analyysi teoksesta Pisces tarkentaa kuvaa Ruohomäen sävellysten tyylipiirteistä. Teosanalyysissä luodaan pohjaa myös Ruohomäen kahden sävellyskauden vertailuun. Jatkotutkimuksen kannalta mielenkiintoiseksi kysymykseksi nousee Ruohomäen kahden sävellyskauden vertailu sekä sävellysteknologian kehityksen ja elektroakustisen musiikin estetiikan suhteen tarkastelu tämän vertailun avulla.

Käsilläolevan tutkielman kohteena on Martin Heideggerin (1889–1976) tulkintatyö, jonka hän varhaisessa ajattelussaan (1919–1927) kohdisti kreikkalaisen filosofian keskeiseen käsitteeseen logos: ”järki”, ”puhekyky”. Tutkielman tavoitteena on selvittää, miten Heidegger tulkitsi tätä käsitettä ja mikä merkitys Heideggerin tulkintatyöllä oli hänen pääteoksensa Sein und Zeit (1927, suom. Oleminen ja aika) kannalta. Työn keskeinen näkemys on, että Heideggerin ajattelu on nähtävä kreikkalaisen järjellisyyskäsityksen kriittisenä arviointina ja uudelleentulkintana. Heideggerin filosofia pohjautui vahvasti näkemykselle, jonka mukaan ajattelumme on hyvin perustavassa mielessä kiinni perinteessä ja sen välittämissä käsityksissä ja tulkinnoissa. Heideggerin mukaan filosofinen tutkimus ei voi koskaan täysin ennakkoluulotonta ja tämän vuoksi kaiken ajattelun on päästävä selville oman tilanteensa historiallisuudesta ja satunnaisuudesta; tieteellinen filosofia ei voi valita systemaattisen ja historiallisen lähestymistavan välillä, vaan sen on oltava olemuksellisesti molempia. Vuosina 1919–1929 Heideggerin historiallisen tulkintatyön ensisijaisena kohteena oli kreikkalainen filosofia, erityisesti Aristoteleen ajattelu. Heideggerin mukaan Aristoteles ei ollut ensimmäinen filosofista ajattelua harjoittanut henkilö, mutta Heidegger näki Aristoteleen tuotannon tiivistävän yhteen länsimaisen ajattelun keskeisimmät ennakkokäsitykset. Tutkielmassa seurataan Heideggerin pyrkimystä tulkita inhimillisen järjellisyyden ilmiötä, jonka juuret Heidegger paikansi Aristoteleen ihmismääritelmään zōon logon ekhon (”järjellinen eläin”). Aristotelesta seurannut skolastinen filosofia omaksui tämän määritelmän muodossa animal rationale, mutta Heidegger painotti, että tällä käännöksellä oli taipumus sivuuttaa se perusta, joka oli vielä ominainen kreikkalaiselle järjen käsitteelle. Sillä Aristoteleelle ja kreikkalaiselle ajattelulle logos ei merkinnyt ainoastaan haluihin ja tunteisiin rinnastuvaa mielen sisäistä kykyä vaan ennen kaikkea yhteisöllisesti jaettua tulkintaa ympäröivästä todellisuudesta. Tämä tulkinta ilmenee jokapäiväisesti keskustelun ja kommunikaation yhteydessä, mutta se on myös olennainen osa tapaamme jäsentää ympäröivää todellisuutta merkitykselliseksi. Heidegger kuitenkin argumentoi, että kreikkalainen ajattelu näki tämän kielellis-diskursiivisen käsittämisen alisteisena inhimillisen kokemuksen perustaville tavoille olla suhteessa todellisuuteen: puhtaalle aistihavainnolle (aisthēsis) sekä intuitiiviselle tajuamiselle (noein). Tutkielma koostuu neljästä luvusta sekä lyhyestä johdannosta. Ensimmäinen luku käsittelee Heideggerin filosofian kantavaa teemaa, kysymystä olemisen mielestä – sekä tämän kysymyksen perustaa kreikkalaisessa ajattelussa. Tämän jälkeen luodaan katsaus Heideggerin fenomenologiseen metodiin, sen ensisijaiseen kohdealueeseen inhimillisessä kokemuksessa sekä fenomenologisen tutkimuksen historialliseen ulottuvuuteen. Toisessa luvussa esitetään puolestaan Heideggerin tulkinta käsitteestä logos. Tulkinnan ymmärtämiseksi on välttämätöntä esittää tiivistetysti Heideggerin tulkinta kreikkalaisesta totuuden käsitteestä. Heideggerin mukaan kreikkalainen ajattelu ymmärsi totuuden monitasoisena ilmiönä, jonka perustavin käyttöyhteys on löydettävissä todellisuuden ilmiöstä. Kolmannessa luvussa pureudutaan niihin piirteisiin, joiden valossa Aristoteles Heideggerin mukaan tulkitsi kielen ja kokemuksen välistä suhdetta. Neljännessä luvussa esitetään, mitä edellä esitetyt oivallukset merkitsivät Heideggerin oman filosofisen projektin kannalta, erityisesti inhimillistä olemassaoloa (Dasein) selvittäneen fundamentaaliontologian kannalta.
