Minä kirjoittajana : Identiteetit, subjektit ja persoonat lukion 1. vuoden opiskelijoiden omaa kirjoittamista pohdiskelevissa teksteissä

Tutkimuksessani tarkastelen kirjoittajaidentiteettejä teksteissä, joissa lukion ensimmäisen vuoden opiskelijat pohdiskelevat omaa kirjoittamistaan. Lähtökohtanani on ajatus narratiivisesta identiteetistä: identiteetti nähdään hermeneuttisena itsen ymmärtämisen prosessina sen sijaan, että sitä pidettäisiin kuvauksena, jonka totuusarvoa olisi relevanttia arvioida. Tutkimuskohteena on kirjoittajaidentiteetti, joten lähestyn aineistoni tekstejä osana prosessia, jossa ihminen ottaa etäisyyttä omaan kirjoittamiseensa ja siten lisää omaa ymmärrystään siitä. Myös sosiaalinen konteksti vaikuttaa tähän identiteettiprosessiin. Lähestyn kirjoittajaidentiteettejä yhteisöllisestä ja yksilöllisestä näkökulmasta, mutta jaossa ei ole kysymys dikotomiasta vaan kahdenlaisesta valotuksesta samaan asiaan: myös yksilö tarvitsee yhteisön, josta erottua. Yhteisöllisyyttä pohtiessani käsittelen nollapersoonakonstruktiota näkökulman jakamisen ja samastumisen tarjoamisen välineenä. Aineistossani nollapersoonakonstruktio on yhtäältä keino käsitellä omaa kokemusta ja toisaalta keino kurkottaa lukijan puoleen ja saada tämä ymmärtämään kirjoittajaa. Hyvin samanlainen merkitys on aineistossani yleistävällä yksikön 2. persoonalla. Molemmat kielen keinot ilmentävät kirjoittajaidentiteettien sosiaalisuutta: lukija edustaa kirjoittajalle sosiaalista yhteisöä, joka halutaan saada ymmärtämään kirjoittajan ratkaisuja ja kokemuksia. Yhteisöllisyyden valossa tarkastelen myös erilaisia keinoja luoda kirjoittajien kollektiivia. Aineistoni lukiolaiset määrittävät teksteissään erilaisia ryhmiä käyttämällä monikon 1. persoonaa tai passiivia. Monikon 1. persoonaa käyttämällä voidaan luoda myös yhteyttä kirjoittajan ja lukijan välillä. Kirjoittajaidentiteetit näyttäytyvät sosiaalisena, sillä kuuluminen johonkin ryhmään esitetään oman kirjoittamisen kannalta olennaisena asiana. Yksilöllisyyttä tuodaan esiin mm. yksikön 1. persoonaa käyttämällä, kun kirjoittaja asettaa itsensä lausuman subjektiksi, joka erottuu puhuteltavasta sinästä. Kirjoittaja ikään kuin määrittää rajansa ja eronsa suhteessa toiseen. Yksikön 1. persoonan lisäksi myös sana itse nostaa esiin eron muihin. Tässäkin suhteessa kirjoittajaidentiteetit näyttäytyvät sosiaalisina. Erilaisten kielellisten keinojen käyttö tuo näkyviin, kuinka ihminen jäsentää omaa suhdettaan toisiin: mihin hän kuuluu ja mistä hän eroaa. Sosiokulttuurisessa kontekstissa on subjektipositioita, joiden välityksellä identiteetit rakentuvat. Tutkimuksessani pohdin yhteisöllisyyttä ja yksilöllisyyttä myös kahden aineistosta konstruoimani subjektiposition avulla. Ensinnäkin esittelen hyvän kirjoittajan malliposition, johon asettuvan kirjoittajan tekstit ovat mm. pitkiä, monipuolisia ja normatiivisen kieliopin mukaisia. Kirjoittajat suhteuttavat itseään tähän positioon: he joko hyväksyvät sen tai asettuvat vastustamaan sitä. Toiseksi esittelen romanttisen kirjoittajan malliposition, johon liittyy mm. inspiraatio ja kirjoittamisen näkeminen itseilmaisuna. Kirjoittajat projisoivat teksteissään itseään ja omaa kirjoittamistaan suhteessa näihin subjektipositioihin, ja kirjoittajaidentiteetti muodostuu kirjoittajan ja tekstiyhteisön välisessä vuorovaikutuksessa.

Kymijoen vaelluskalojen nousureittien avaamisen kustannusten ja hyötyjen arviointi

The objective of this thesis is to evaluate different means of increasing natural reproduction of migratory fish, especially salmon, in the river Kymijoki. The original stocks of migratory fish in Kymijoki were lost by the 1950s because of hydropower plants and worsened quality of water in the river. Nowadays the salmon stocks is based on hatchery-reared fish, even though there is significant potential of natural smolt production in the river. The main problem in the natural reproduction is that the migratory fish cannot ascend to the reproduction areas above the Korkeakoski and Koivukoski hydropower plants. In this thesis alternative projects which aim to open these ascencion routes and their costs and benefits are evaluated. The method used in the evaluation is social cost-benefit analysis. The alternative projects evaluated in this thesis consist of projects that aim to change the flow patterns between the eastern branches of Kymijoki and projects that involve building a fish ladder. Also different combinations of these projects are considered. The objective of this thesis is to find the project that is the most profitable to execute; this evaluation can be done in comparing the net present values of the projects. In addition to this, a sensitivity analysis will be made on the parameter values that are most uncertain. We compare the net present values of the projects with the net present values of hatchery-reared smolt releases, so we can evaluate, if the projects or the smolt releases are more socially profitable in the long term. The results of this thesis indicate that especially the projects that involve building a fish ladder next to the Korkeakoski hydropower plant are the most socially profitable. If this fish ladder would be built, the natural reproduction of salmon in the Kymijoki river could become so extensive, that hatchery-reared smolt releases could even be stopped. The results of the sensivity analysis indicate that the net present values of the projects depend especially on the initial smolt survival rate of wild salmon and the functioning of the potential fish ladder in Korkeakoski. Also the changes of other parameter values influence the results of the cost-benefit analysis, but not as significantly. When the net present values of the projects and the smolt releases are compared, the results depend on which period of time is selected to count the average catches of reared salmon. If the average of the last 5 years catches is used in counting the net benefits of smolt releases, all the alternative projects are more profitable than the releases. When the average of the last 10 years is used, only building of the fish ladder in Korkeakoski and all the project combinations are more profitable than the smolt releases.

Puukaupan säännöt : Yksityismetsänomistajien ja metsäteollisuuden puukauppa Itä-Suomessa 1919 - 1939

The Finnish forest industry bought more than half of the timber used in factories and sawmills in the 1930s from non-industrial private forests (NIPF). This research investigates the rules conformed to this timber trade. The main research questions are: what were the rules that influenced the timber trade; and by whom they were set up? Attention is also paid to the factors which advanced the forest owners’ negotiation possibilities. A variety of sources were used: legal and company statutes, timber trade contracts, archives of the forest companies and organisations. Moreover, the written reminiscences collected by the Finnish Literature Society in the early 1970s were used to analyse the views of individual sellers and buyers. An institutional economics approach was applied as the theoretical framework of this study. In the timber trade the seller (forest owner) and the buyer (the employee of the forest company) agreed to the rules of the timber trade. They agreed about the amount and the price of the timber on sale, but also rules concerning, e.g., timber marking and harvesting. The forest companies had a strong control over the written contracts. Neither the private forest owners nor the forest organisations had much influence over these contracts. However, they managed to influence the rules which could not be found in the contracts. These written and unwritten rules regulated, for instance, the timber marking and measurement. The forest organisations such as Central Forestry Board Tapio (Keskusmetsäseura Tapio) and associations of forest owners (metsänhoitoyhdistykset) helped private forest owners in gaining more control over the timber marking. In timber marking, the forest owner selected trees to be included in the timber trade and gained more information, which he could use in the negotiations. The other rule, which was changed despite forest companies’ resistance, was the timber measurement. The Central Union of Agricultural Producers (MTK) negotiated with the Central Association of Finnish Woodworking Industries (SPKL) about changing the rules of the measurement practices. Even though SPKL did not support any changes, the new timber measurement law was accepted in the year 1938. The new law also created a supervisory authority to solve possible disagreements. Despite this the forest companies were still in charge of the measurement process in most cases. The private forest owners attained changes in the rules of the timber trade mainly during the 1930s. Earlier the relative weakness of the private forest organisations had diminished their negotiation positions. This changed in the 1930s as the private forest owners and their organisations became more active. At the same time the forest industry experienced a shortage of timber, especially pulp wood, and this provided the private forest owners with more leverage.

Herpes Simplex Virus Infection, Pathological Pain and Recurrent Lymphocytic Meningitis

Background: Aims of the study were: (i) to characterise the clinical picture, immunological features and changes in brain morphology and function in patients with widespread unilateral pain and HSV-infections, and (ii) to analyse the prevalence, clinical symptoms and immunological predisposing factors of HSV-2 induced recurrent lymphocytic meningitis (RLM) in Southern Finland. Patients and methods: Patients for the studies were recruited from the Pain Clinic, and from the Department of Neurology, at Helsinki University Central Hospital. Plasma concentrations of IgM, IgA, IgG, and IgG1-4, and serum concentrations of C3, C4 were measured. Serological anti-HSV-1 and -2 antibody status was tested. C4 genotyping, HLA-A, HLA-B and HLA-DRB1 typing, MBL2 genotyping, and IgG1 and IgG3 allotyping (Gm) were performed. Clinical neurological examination, quantitative sensory testing, skin biopsy, and functional magnetic resonance imaging were also performed. Results: HSV probably has a role in the generation of a pathological pain state. Low serum IgG1 and IgG3 levels, made the patients vulnerable for recurring HSV infections. Both functional and structural changes were observed in the brain pain-processing areas in the patients: they had less pain-related activity in the insular cortices bilaterally, in the anterior cingular cortex (ACC), and in the thalamus, and the gray matter density was lower in the ACC, in the frontal and prefrontal cortices. In the meningitis studies it was shown that RLM is more common and less benign than previously reported, and that neuropathic pain is frequently present both during and after meningitis episodes. HLA-DRB1*01, HLA-B*27, and low IgG1 levels are predisposing factors for RLM. Conclusions: Patients are vulnerable to recurrent HSV infections because of subtle immunological abnormalities. HSV causes diverse clinical manifestations. First, the herpes simplex virus, or the inflammatory process triggered by it, may cause pathological widespread pain probably by activating glial cells in the CNS. In these patients, signs of alterations in the brain pain-processing areas can be demonstrated by functional brain imaging methods. Secondly, HSV-2 induced RLM is a rare complication of HSV-2 virus. The predisposing factors include low IgG1 subclass levels, HLA-DRB1*01 and HLA –B*27 genotypes. Neuropathic pain is frequently associated with RLM.

Pathological changes at the target tissue level in Sjögren's syndrome and their effect on the exocrine function of the salivary glands

Sjögren s syndrome (SS) is a common autoimmune disease affecting the lacrimal and salivary glands. SS is characterized by a considerable female predominance and a late age of onset, commonly at the time of adreno- and menopause. The levels of the androgen prohormone dehydroepiandrosterone-sulphate (DHEA-S) in the serum are lower in patients with SS than in age- and sex-matched healthy control subjects. The eventual systemic effects of low androgen levels in SS are not currently well understood. Basement membranes (BM) are specialized layers of extracellular matrix and are composed of laminin (LM) and type IV collagen matrix networks. BMs deliver messages to epithelial cells via cellular LM-receptors including integrins (Int) and Lutheran blood group antigen (Lu). The composition of BMs and distribution of LM-receptors in labial salivary glands (LSGs) of normal healthy controls and patients with SS was assessed. LMs have complex and highly regulated distribution in LSGs. LMs seem to have specific tasks in the dynamic regulation of acinar cell function. LM-111 is important for the normal acinar cell differentiation and its expression is diminished in SS. Also LM-211 and -411 seem to have some acinar specific functional tasks in LSGs. LM-311, -332 and -511 seem to have more general structure maintaining and supporting roles in LSGs and are relatively intact also in SS. Ints α3β1, α6β1, α6β4 and Lu seem to supply structural basis for the firm attachment of epithelial cells to the BM in LSGs. The expression of Ints α1β1 and α2β1 differed clearly from other LM-receptors in that they were found almost exclusively around the acini and intercalated duct cells in salivons suggesting some type of acinar cell compartment-specific or dominant function. Expression of these integrins was lower in SS compared to healthy controls suggesting that the LM-111 and -211-to-Int α1β1 and α2β1 interactions are defective in SS and are crucial to the maintenance of the acini in LSGs. DHEA/DHEA-S concentration in serum and locally in saliva of patients with SS seems to have effects on the salivary glands. These effects were first detected using the androgen-dependent CRISP-3 protein, the production and secretion of which were clearly diminished in SS. This might be due to the impaired function of the intracrine DHEA prohormone metabolizing machinery, which fails to successfully convert DHEA into its active metabolites in LSGs. The progenitor epithelial cells from the intercalated ductal area of LSGs migrate to the acinar compartment and then undergo a phenotype change into secretory acinar cells. This migration and phenotype change seem to be regulated by the LM-111-to-Int α1β1/Int α2β1 interactions. Lack of these interactions could be one factor limiting the normal remodelling process. Androgens are effective stimulators of Int α1β1 and α2β1 expression in physiologic concentrations. Addition of DHEA to the culture medium had effective stimulating effect on the Int α1β1 and α2β1 expression and its effect may be deficient in the LSGs of patients with SS.

Struggling over subjectivity: A discursive analysis of strategic development in a group

We have seen growing interest in discursive perspectives on strategy. This perspective holds great promise for development of an understanding on how strategy discourse and subjectivity are intertwined. We wish to add to this existing research by outlining a discursive struggle approach to subjectivity. To understand the complex subjectification and empowering/disempowering effects of organizational strategy discourse, this approach focuses on organization-specific discourse mobilizations an various ways of resistance. Drawing on an analysis of the discourses and practices of ‘strategic development’ in an engineering and consulting group we provide an empirical illustration of such struggles over subjectivity. In particular, we report three examples of competing ways of making sense of and giving sense to strategic development, with specific subjectification tendencies. First, we show how corporate management can mobilize and appropriate a specific kind of discourse to attempt to gain control of the organization, which tends to reproduce managerial hegemony, but also trigger discursive and other forms of resistance. Second, we will illustrate how middle managers resist this hegemony by initiating a strategy discourse of their own to create room for manoeuvre in controversial situations. Third, we show how project engineers can distance themselves from managerial-initiated strategy discourses to maintain a viable identity despite all kinds of pressures. Although our examples are case-specific, we believe that similar discursive dynamics also characterize strategizing in other organizations.

Ruismallasuute vähägluteenisessa kauraleivonnassa

Tutkielman kirjallisuuskatsauksessa tarkasteltiin kauran leivontateknologisia ominaisuuksia, entsyymiaktiivista leivontaa ja ruismaltaan hyödyntämistä vähägluteenisessa leivonnassa. Kokeellisessa osiossa tutkittiin ruismallashapantaikinasta valmistetun uutteen vaikutusta kaurataikinan viskositeettiin ja kauraleivän ominaisuuksiin. Työn tarkoituksena oli kehittää maultaan ja rakenteeltaan onnistunut rukiinmakuinen kauraleipä. Ruismaltaan entsyymien annettiin pilkkoa keliaakikolle haitallisia rukiin prolamiineja hapantaikinaprosessissa. Hapantaikinasta erotettiin uute sentrifugoimalla. Leivontakokeisiin käytettiin entsyymiaktiivista ja kuumentamalla inaktivoitua uutetta. Uutteella korvattiin taikinavettä 15, 25 ja 30 % (taikinan painosta). Leivonta toteutettiin miniatyyrikoossa, vuokaleivontana 20 g:n taikinapaloja käyttäen. Taikinoiden viskositeetti mitattiin tarkoituksena seurata beetaglukaanin hydrolyysiä. Rukiin makua mitattiin koulutetun raadin avulla. Happaman uutteen lisäys laski taikinan pH-arvoa noin 5,8:sta noin 4,4:ään. Entsyymiaktiivisen uutteen lisäys laski taikinan viskositeettia ja inaktivoitu uute puolestaan kasvatti sitä. Leipien sisus tiivistyi, jolloin mitatut sisuksen kovuudet kasvoivat uutteen lisäyksen myötä. Uutelisäys paransi leipien makua ja aromia. Uutteen vaikutuksesta leipien huokoset olivat pienempiä ja ne jakaantuivat tasaisemmin leipämatriisiin. Jos uutetta käytettiin inaktivoituna, leipien murenevuus kasvoi. Tutkimuksessa kehitetyn teknologian avulla oli mahdollista valmistaa hyvänlaatuinen, rukiinmakuinen kauraleipä myös ilman että uutteen entsyymit inaktivoitiin keittämällä. Tähän vaikutti ilmeisesti taikinan alhainen pH, joka inhiboi alfa-amylaasia, ja kauratärkkelyksen korkea liisteröitymislämpötila, jolloin entsyymien inaktivoituminen paiston aikana tapahtui ennen kuin tärkkelys tuli alttiiksi liialliselle pilkkoutumiselle. Tämä mahdollistaa uutteen käytön osana leivontaprosessia ilman inaktivointia. Hapantaikinafermentaatio osana gluteenitonta leivontaa havaittiin toimivaksi yhdistelmäksi, sillä se paransi leivän väriä, makua ja rakennetta. Myös leivän homeeton aika parani jo vähäisenkin uutelisäyksen vaikutuksesta. Näyttää siltä, että tämän teknologian avulla on mahdollista tuoda esille pitkään kaivattua rukiin makua vähägluteenisten kauraleipien valikoimassa. Laskennallisesti ja aiempiin tuloksiin tukeutuen, voitiin päätellä, että leivän prolamiinipitoisuudessa on mahdollista päästä tasolle 63,5 mg/kg, mutta jatkokehityksen avulla päästäisiin luultavasti vielä parempiin tuloksiin.

Young Actors in Transnational Agoras : Multi-sited Ethnography of Cosmopolitan Micropolitical Orientations

This study examines young people s political participation in transnational meetings. Methodologically the study aims to shed light on multi-sited global ethnography. Young people are viewed here as a social age group sensitive to critical, alternative and even radical political participation. The diversity of the young actors and their actions is captured by using several different methods. What is more, the study spurs us coming from the Global North to develop social science research towards methodological cosmopolitanism and to consider our research practices from a moral cosmopolitan perspective. The research sites are the EU Presidency Youth Event (2006 Hyvinkää, Finland), the Global Young Greens Founding Conference (2007 Nairobi, Kenya), the European Social Forum (2008 Malmö, Sweden) and three World Social Forums (2006 Bamako, Mali; 2007 Nairobi Kenya and 2009 Belém, Brazil). The data consists of participant observation, documents and media articles of the meetings, interviews, photos, video, and internet data. This multidisciplinary study combines youth research, development studies, performative social science and political sociology. In this research the diverse field of youth political participation in transnational agoras is studied by using a cross-table of cosmopolitan resources (or the lack of them) and everydaymakers expert citizen dichotomy. First, the young participants of the EU Presidency youth event are studied as an example of expert citizens with cosmopolitan resources (these resources include, for example, language skills, higher education and international social network). Second, the study analyses those everyday-makers who use performative politics to demonstrate their political missions here and now. But in order to make the social movement global they need cosmopolitan resources to be able to use the social media tools and work globally. Third, the study reflects upon the difficulties of reaching those actors who lack cosmopolitan resources, either everyday-makers or expert citizens. The go-along method and the use of the interpreters are shown as ways to reach these young people s political missions. Fourth, the research underlines the importance of contact zones (i.e. spaces or situations where the aforementioned orientations and their differences temporarily disappear or weaken) for deeper democracy and for boosted dialogue between different kinds of participants.
