Climate driven changes in temperature, pH and food quality : effects on copepod reproduction

Increased emissions of greenhouse gases into the atmosphere are causing an anthropogenic climate change. The resulting global warming challenges the ability of organisms to adapt to the new temperature conditions. However, warming is not the only major threat. In marine environments, dissolution of carbon dioxide from the atmosphere causes a decrease in surface water pH, the so called ocean acidification. The temperature and acidification effects can interact, and create even larger problems for the marine flora and fauna than either of the effects would cause alone. I have used Baltic calanoid copepods (crustacean zooplankton) as my research object and studied their growth and stress responses using climate predictions projected for the next century. I have studied both direct temperature and pH effects on copepods, and indirect effects via their food: the changing phytoplankton spring bloom composition and toxic cyanobacterium. The main aims of my thesis were: 1) to find out how warming and acidification combined with a toxic cyanobacterium affect copepod reproductive success (egg production, egg viability, egg hatching success, offspring development) and oxidative balance (antioxidant capacity, oxidative damage), and 2) to reveal the possible food quality effects of spring phytoplankton bloom composition dominated by diatoms or dinoflagellates on reproducing copepods (egg production, egg hatching, RNA:DNA ratio). The two copepod genera used, Acartia sp. and Eurytemora affinis are the dominating mesozooplankton taxa (0.2 – 2 mm) in my study area the Gulf of Finland. The 20°C temperature seems to be within the tolerance limits of Acartia spp., because copepods can adapt to the temperature phenotypically by adjusting their body size. Copepods are also able to tolerate a pH decrease of 0.4 from present values, but the combination of warm water and decreased pH causes problems for them. In my studies, the copepod oxidative balance was negatively influenced by the interaction of these two environmental factors, and egg and nauplii production were lower at 20°C and lower pH, than at 20°C and ambient pH. However, presence of toxic cyanobacterium Nodularia spumigena improved the copepod oxidative balance and helped to resist the environmental stress, in question. In addition, adaptive maternal effects seem to be an important adaptation mechanism in a changing environment, but it depends on the condition of the female copepod and her diet how much she can invest in her offspring. I did not find systematic food quality difference between diatoms and dinoflagellates. There are both good and bad diatom and dinoflagellate species. Instead, the dominating species in the phytoplankton bloom composition has a central role in determining the food quality, although copepods aim at obtaining as a balanced diet as possible by foraging on several species. If the dominating species is of poor quality it can cause stress when ingested, or lead to non-optimal foraging if rejected. My thesis demonstrates that climate change induced water temperature and pH changes can cause problems to Baltic Sea copepod communities. However, their resilience depends substantially on their diet, and therefore the response of phytoplankton to the environmental changes. As copepods are an important link in pelagic food webs, their future success can have far reaching consequences, for example on fish stocks.

Understanding the in vitro dissolution rate of glasses with respect to future clinical applications

Glass is a unique material with a long history. Several glass products are used daily in our everyday life, often unnoticed. Glass can be found not only in obvious applications such as tableware, windows, and light bulbs, but also in tennis rackets, windmill turbine blades, optical devices, and medical implants. The glasses used at present as implants are inorganic silica-based melt-derived compositions mainly for hard-tissue repair as bone graft substitute in dentistry and orthopedics. The degree of glass reactivity desired varies according to implantation situation and it is vital that the ion release from any glasses used in medical applications is controlled. Understanding the in vitro dissolution rate of glasses provides a first approximation of their behavior in vivo. Specific studies concerning dissolution properties of bioactive glasses have been relatively scarce and mostly concentrated to static condition studies. The motivation behind this work was to develop a simple and accurate method for quantifying the in vitro dissolution rate of highly different types of glass compositions with interest for future clinical applications. By combining information from various experimental conditions, a better knowledge of glass dissolution and the suitability of different glasses for different medical applications can be obtained. Thus, two traditional and one novel approach were utilized in this thesis to study glass dissolution. The chemical durability of silicate glasses was tested in water and TRIS-buffered solution at static and dynamic conditions. The traditional in vitro testing with a TRISbuffered solution under static conditions works well with bioactive or with readily dissolving glasses, and it is easy to follow the ion dissolution reactions. However, in the buffered solution no marked differences between the more durable glasses were observed. The hydrolytic resistance of the glasses was studied using the standard procedure ISO 719. The relative scale given by the standard failed to provide any relevant information when bioactive glasses were studied. However, the clear differences in the hydrolytic resistance values imply that the method could be used as a rapid test to get an overall idea of the biodegradability of glasses. The standard method combined with the ion concentration and pH measurements gives a better estimate of the hydrolytic resistance because of the high silicon amount released from a glass. A sensitive on-line analysis method utilizing inductively coupled plasma optical emission spectrometer and a flow-through micro-volume pH electrode was developed to study the initial dissolution of biocompatible glasses. This approach was found suitable for compositions within a large range of chemical durability. With this approach, the initial dissolution of all ions could be measured simultaneously and quantitatively, which gave a good overall idea of the initial dissolution rates for the individual ions and the dissolution mechanism. These types of results with glass dissolution were presented for the first time during the course of writing this thesis. Based on the initial dissolution patterns obtained with the novel approach using TRIS, the experimental glasses could be divided into four distinct categories. The initial dissolution patterns of glasses correlated well with the anticipated bioactivity. Moreover, the normalized surface-specific mass loss rates and the different in vivo models and the actual in vivo data correlated well. The results suggest that this type of approach can be used for prescreening the suitability of novel glass compositions for future clinical applications. Furthermore, the results shed light on the possible bioactivity of glasses. An additional goal in this thesis was to gain insight into the phase changes occurring during various heat treatments of glasses with three selected compositions. Engineering-type T-T-T curves for glasses 1-98 and 13-93 were stablished. The information gained is essential in manufacturing amorphous porous implants or for drawing of continuous fibers of the glasses. Although both glasses can be hot worked to amorphous products at carefully controlled conditions, 1-98 showed one magnitude greater nucleation and crystal growth rate than 13-93. Thus, 13-93 is better suited than 1-98 for working processes which require long residence times at high temperatures. It was also shown that amorphous and partially crystalline porous implants can be sintered from bioactive glass S53P4. Surface crystallization of S53P4, forming Na2O∙CaO∙2SiO2, was observed to start at 650°C. The secondary crystals of Na2Ca4(PO4)2SiO4, reported for the first time in this thesis, were detected at higher temperatures, from 850°C to 1000°C. The crystal phases formed affected the dissolution behavior of the implants in simulated body fluid. This study opens up new possibilities for using S53P4 to manufacture various structures, while tailoring their bioactivity by controlling the proportions of the different phases. The results obtained in this thesis give valuable additional information and tools to the state of the art for designing glasses with respect to future clinical applications. With the knowledge gained we can identify different dissolution patters and use this information to improve the tuning of glass compositions. In addition, the novel online analysis approach provides an excellent opportunity to further enhance our knowledge of glass behavior in simulated body conditions.

Keskusteluja vuokratyöstä. Vuokratyön diskursiivinen rakentuminen Suomessa

1990-luvun alussa lainsäädäntö ja työmarkkinajärjestöt määrittelivät Suomessa, että vuokratyötä tuli käyttää vain tilapäiseen työvoimatarpeeseen, esimerkiksi sijaisuuksiin ja ruuhkahuippuihin. Joillakin aloilla vuokratyö oli työnantajien ja työntekijöiden yhteissopimuksella kielletty. Vaikka vuokratyösuhteet saivat jo 1980-luvulla niin Suomessa kuin kansainvälisestikin maineen työsuhdekeinotteluna, alkoi vuokratyön määrä Suomessa kasvaa 1990-luvun puolivälissä ja erityisesti tultaessa 2000-luvulle. Suomalaiset akateemiset tutkijat eivät ole juuri vuokratyöstä kiinnostuneet. Aiemmat, harvalukuiset tutkimukset ovat keskittyneet lähinnä työyhteisöjen ja työntekijöiden kokemuksiin sekä vuokratyön työehtoihin. Vuokratyö ymmärretäänkin edelleen lähinnä työntekijän subjektiivisena kokemuksena. Vuokratyössä on kuitenkin kysymys paitsi kokemuksista, myös yhteiskunnallisesta valtakamppailusta, jossa diskursiivisin keinoin pyritään vaikuttamaan ilmiöön nimeltä vuokratyö, laajemmin ilmiöön nimeltä työmarkkinat, sekä toisaalta kansalaisten käsityksiin työelämän ”normaalista”. Käsillä oleva tutkimus laajentaa ymmärrystä vuokratyöstä tarkastelemalla ilmiötä lainsäädännön, uutisoinnin ja markkinoinnin rakentamien julkisten käsitysten ja merkityksenantojen kautta. Teoreettisena viitekehyksenä käytän hallinnan ja työprosessin säätelyn teoriaperinteitä. Se, miten työmarkkinoiden muutosta ja uusia työsuhdemuotoja politiikassa, mediassa, lainsäädännössä, tai työpaikan kahvipöytäkeskusteluissa perustellaan ja tehdään ymmärrettäväksi, on samalla työelämään kiinnitettävien arvojen, merkitysten ja toimijuuksien luomista, rajaamista ja kuvailua. Työelämäpuheessa ei siis ole kyse vain talouden lainalaisuuksista, kansantalouden toimivuudesta, tai yritysten kilpailukyvystä, vaan myös ja erityisesti niiden toimijoiden luomisesta, määrittelemisestä ja legitimoimisesta, jotka työelämän kentällä saavat toimia ja tulevat palkituiksi. Säätelyn ja hallinnan näkökulmasta on relevanttia tarkastella millaisilla käsitteillä ja merkityksillä vuokratyötä ilmiönä rakennetaan . Tutkimuskysymyksinä esitän: 1) Miten ja millä perusteilla vuokratyöstä rakennettiin Suomessa legitiimi tapa työllistää ja työllistyä? 2) Millaisia työntekijäideaaleja vuokratyöhön liittyvissä keskusteluissa rakennetaan? Tutkimusaineistona tarkastelen lainsäädäntöön liittyviä dokumentteja, Helsingin Sanomien uutisointia, vuokratyöyritysten markkinointimateriaaleja, sekä vuokratyöyritysten edustajien haastatteluita. Analyysimenetelmänä käytän kriittistä diskurssianalyysia. Tämä menetelmä mahdollistaa puheen ja dokumenttien tarkastelun sosiaalisena toimintana, jolla eri toimijat pyrkivät osallistumaan yhteiskunnassa hyväksyttyjen ja tunnustettujen käsitysten ja toimintavaihtoehtojen rakentamis-, tulkinta- ja määrittelyprosesseihin. Tutkimukseni päätuloksena esitän, että vuokratyöstä muodostui legitiimi tapa työllistää Suomessa 1990-luvulla, koska vuokratyö käsitteellistettiin sekä lainsäädännön että median diskursseissa ennen kaikkea ratkaisuksi työttömyyteen. Toisaalta vuokratyö käsitteellistettiin vain marginaalisten työntekijäryhmien (naiset ja opiskelijat) rooliksi, jolloin se ei liittynyt miesvaltaisten työpaikkojen arkeen. Ratkaisuna työttömyyteen vuokratyö myös samalla luonnollistettiin osaksi yleisempää työmarkkinakehitystä, jolle ”kukaan ei voi mitään”. 2000-luvulla vuokratyö jatkoi voittokulkuaan ja rakentui pysyväksi ilmiöksi, koska työlainsäädännön uudistus institutionalisoi vuokratyön työehtosopimusmenettelyyn, jolloin sen ”salonkikelpoisuus” ja normaalius vahvistettiin. Vaikka työehtosopimusasia oli ratkaisuna merkittävä, nousi vuokratyön osalta itse työehtosopimus tärkeämmäksi kuin sen sisältö. Työehtosopimuksilla ei kuitenkaan pystytty vaikuttamaan esimerkiksi vuokratyöntekijän olemattomaan työsuhdeturvaan. Lisäksi työnantajapuhe käsitteellistää vuokratyön 2000-luvulla ennen kaikkea työmarkkinavaihtoehdoksi, vapautta ja monipuolisia työkokemuksia tarjoavaksi työmarkkinoiden katalysaattoriksi. Vuokratyö on tässä merkitysavaruudessa työntekijöille ”vain” yksi tapa työllistyä ja löytää oma tiensä työmarkkinoille, ei suinkaan työnantajien sanelema pakko. Työntekijöihin kohdistuva hallintapuhe niin mediassa kuin työnantajien haastatteluissakin pyrkii puolestaan rakentamaan ideaalityöntekijäkuvaksi yrittäjämäisen oman elämänsä toimitusjohtajan. Työnantajien diskursseissa kaikuvatkin työntekijään kohdistuva vaatimus itse itsensä ohjaamisesta sekä työntekijäidentiteetin muotoilemisesta joustavuutta, sopeutuvuutta, vaihtelua ja jatkuvaa muutosta vähintäänkin sietäväksi, mutta mieluiten näitä ominaisuuksia jopa aktiivisesti hakevaksi ja arvostavaksi. Työmarkkinoiden toimijana on nimenomaisesti yksilö, jonka mahdollisuudet menestyä ovat vain ja ainoastaan hänen omissa käsissään. Työntekijän roolin korostaminen aktiivisena toimijana ja vuokratyöstä ”oikeita”, norminmukaisia sisältöjä löytävänä pärjääjänä on diskursiivisesti hallittua yritystä ohjata työntekijöitä näkemään sekä itsensä tietynlaisina toimijoina että työmarkkinat tietyllä tavalla toimivina. Vuokratyössä ei ole kyse vain työntekijöiden yksilöllisistä tai yksittäisistä kokemuksista. Vuokratyö on yhteiskunnallisen merkityskamppailun tulos, jossa käyttövoimana ovat toimineet hallinnalliset ja säätelyyn pyrkivät käsitteellistykset työllisyydestä, yksilön valinnasta ja koko yhteiskunnan edusta. Hallinnan ja säätelyn näkökulmasta katsottuna vuokratyö on myös merkinnyt säätelyn liukumista tasa-arvoa, yhdenmukaista kohtelua ja työntekijän suojelua korostavasta viranomaisten ja poliittisten toimijoiden suorittamasta työmarkkinoiden kollektiivisesta säätelystä työnantajien ylläpitämään työntekijän persoonan ja käyttäytymisen hegemoniseen, yksilölliseen säätelyyn.

Blood-gas and electrolyte values for Amazon parrots (Amazona aestiva)

The aim was to provide reference data for blood gas/acid-base status and electrolytes for non-anesthetized Amazon parrots (Amazona aestiva). Thirty-five adult parrots from Tietê ecologic park were utilized. Arterial blood (0.3ml) samples were anaerobically collected from the superficial ulnar artery in heparinized (sodium heparin) 1-ml plastic syringes. The samples were immediately analyzed through a portable analyzer (i-STAT*, Abbot, Illinois, USA) with cartridges (EG7+). These data were grouped in such a way as to present both mean and standard deviation: body weight (360±37g), respiratory rate (82±33 b/m), temperature (41.8±0.6°C), hydrogen potential (7.452±0.048), carbon dioxide partial pressure (22.1±4.0mmHg), oxygen partial pressure (98.1±7.6mmHg), base excess (-7.9±3.1), plasma concentration of bicarbonate ions (14.8±2.8mmol/L), oxygen saturation (96.2±1.1%), plasma concentration of sodium (147.4±2.2mmol/L), plasma concentration of potassium (3.5±0.53mmol/L), plasma concentration of calcium (0.8±0.28mmol/L), hematocrit (38.7±6.2%) and concentration of hemoglobin (13.2±2.1g/dl). This study led us to conclude that, although the results obtained showed hypocapnia and low values of bicarbonate and base excess, when compared to other avian species, these data are very similar. Besides, in spite of the equipment being approved only for human beings, it was considered simple and very useful in the analysis of avian blood samples. By using this equipment we were able to provide references data for non-anaesthetized Amazon parrots.

Towards novel biogas upgrading processes

Biogas production has considerable development possibilities not only in Finland but all over the world since it is the easiest way of creating value out of various waste fractions and represents an alternative source of renewable energy. Development of efficient biogas upgrading technology has become an important issue since it improves the quality of biogas and for example facilitating its injection into the natural gas pipelines. Moreover, such upgrading contributes to resolving the issue of increasing CO2 emissions and addresses the increasing climate change concerns. Together with traditional CO2 capturing technologies a new class of recently emerged sorbents such as ionic liquids is claimed as promising media for gas separations. In this thesis, an extensive comparison of the performance of different solvents in terms of CO2 capture has been performed. The focus of the present study was on aqueous amine solutions and their mixtures, traditional ionic liquids, ‘switchable’ ionic liquids and poly(ionic liquid)s in order to reveal the best option for biogas upgrading. The CO2 capturing efficiency for the most promising solvents achieved values around 50 - 60 L CO2 / L absorbent. These values are superior to currently widely applied water wash biogas upgrading system. Regeneration of the solvent mixtures appeared to be challenging since the loss of initial efficiency upon CO2 release was in excess of 20 - 40 vol %, especially in the case of aqueous amine solutions. In contrast, some of the ionic liquids displayed reversible behavior. Thus, for selected “switchable” ionic and poly(ionic liquid)s the CO2 absorption/regeneration cycles were performed 3 - 4 times without any notable efficiency decrease. The viscosity issue, typical for ionic liquids upon CO2 saturation, was addressed and the information obtained was evaluated and related to the ionic interactions. The occurrence of volatile organic compounds (VOCs) before and after biogas upgrading was studied for biogas produced through anaerobic digestion of waste waters sludge. The ionic liquid [C4mim][OAc] demonstrated its feasibility as a promising scrubbing media and exhibited high efficiency in terms of the removal of VOCs. Upon application of this ionic liquid, the amount of identified VOCs was diminished by around 65 wt %, while the samples treated with the aqueous mixture of 15 wt % N-methyldiethanolamine with addition of 5 wt % piperazine resulted in 32 wt % reduction in the amounts of volatile organic compounds only.

Detection of Pathologic Changes Following Traumatic Brain Injury Using Magnetic Resonance Imaging

Background: Approximately two percent of Finns have sequels after traumatic brain injury (TBI), and many TBI patients are young or middle-aged. The high rate of unemployment after TBI has major economic consequences for society, and traumatic brain injury often has remarkable personal consequences, as well. Structural imaging is often needed to support the clinical TBI diagnosis. Accurate early diagnosis is essential for successful rehabilition and, thus, may also influence the patient’s outcome. Traumatic axonal injury and cortical contusions constitute the majority of traumatic brain lesions. Several studies have shown magnetic resonance imaging (MRI) to be superior to computed tomography (CT) in the detection of these lesions. However, traumatic brain injury often leads to persistent symptoms even in cases with few or no findings in conventional MRI. Aims and methods: The aim of this prospective study was to clarify the role of conventional MRI in the imaging of traumatic brain injury, and to investigate how to improve the radiologic diagnostics of TBI by using more modern diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI) techniques. We estimated, in a longitudinal study, the visibility of the contusions and other intraparenchymal lesions in conventional MRI at one week and one year after TBI. We used DWI-based measurements to look for changes in the diffusivity of the normal-appearing brain in a case-control study. DTI-based tractography was used in a case-control study to evaluate changes in the volume, diffusivity, and anisotropy of the long association tracts in symptomatic TBI patients with no visible signs of intracranial or intraparenchymal abnormalities on routine MRI. We further studied the reproducibility of different tools to identify and measure white-matter tracts by using a DTI sequence suitable for clinical protocols. Results: Both the number and extent of visible traumatic lesions on conventional MRI diminished significantly with time. Slightly increased diffusion in the normal-appearing brain was a common finding at one week after TBI, but it was not significantly associated with the injury severity. Fractional anisotropy values, that represent the integrity of the white-matter tracts, were significantly diminished in several tracts in TBI patients compared to the control subjects. Compared to the cross-sectional ROI method, the tract-based analyses had better reproducibility to identify and measure white-matter tracts of interest by means of DTI tractography. Conclusions: As conventional MRI is still applied in clinical practice, it should be carried out soon after the injury, at least in symptomatic patients with negative CT scan. DWI-related brain diffusivity measurements may be used to improve the documenting of TBI. DTI tractography can be used to improve radiologic diagnostics in a symptomatic TBI sub-population with no findings on conventional MRI. Reproducibility of different tools to quantify fibre tracts vary considerably, which should be taken into consideration in the clinical DTI applications.

Sivistyksestä sivilisaatioon. Kulttuurikäsitys J. V. Snellmanin historiallisessa ajattelussa

From Bildung to Civilisation. Conception of Culture in J. V. Snellman’s Historical Thinking The research explores Johan Vilhelm Snellman’s (1806–1881) conception of culture in the context of his historical thinking. Snellman was a Finnish, Swedish-speaking journalist, teacher and thinker, who held a central position in the Finnish national discourse during the nineteenth century. He has been considered as one of the leading theorists of a Finnish nation, writing widely about the themes such as the advancement of the national education, Finnish language and culture. Snellman is already a widely studied person in Finnish intellectual history, often characterised as a follower of G. W. F. Hegel’s philosophical system. My own research introduces a new kind of approach on Snellman’s texts, emphasising the conceptual level of his thought. With this approach, my aim is to broaden the Finnish research tradition on conceptual history. I consider my study as a cultural history of concepts, belonging also to the field of intellectual history. My focus is on one hand on the close reading of Snellman’s texts and on the other hand on contextualising his texts to the European intellectual tradition of the time. A key concept of Snellman’s theoretical thinking is his concept of bildning, which can be considered as a Swedish counterpart of the German concept of Bildung. The Swedish word incorporated all the main elements of the German concept. It could mean education or the so-called high culture, but most fundamentally it was about the self-formation of the individual. This is also the context in which Snellman’s concept of bildning has often been interpreted. In the study, I use the concept of bildning as a starting point of my research but I broaden my focus on the cognate concepts such as culture (kultur), spirit (anda) and civilisation. The purpose of my study is thus to illustrate how Snellman used and modified these concepts and from these observations to draw a conclusion about the nature of his conception of culture. Snellman was an early Finnish philosopher of history but also interested in the practice of the writing of history. He did not write any historical presentations himself but followed the publications in the field of history and introduced European historical writing to the Finnish, Swedish-speaking reading audience in his newspapers. The primary source material consists of different types of Snellman’s texts, including philosophical writings, lecture material, newspaper articles and private letters. I’m reading Snellman’s texts in the context of other texts produced both by his Finnish predecessors and contemporaries and by Swedish, German and French writers. Snellman’s principal philosophical works, Versuch einer spekulativen Entwicklung der Idee der Persönlichkeit (1841) and Läran om staten (1842), were both written abroad. Both of the works were contributions to contemporary debates on the international level, especially in Germany and Sweden. During the 1840s and 1850s Snellman had two newspapers of his own, Saima and Litteraturblad, which were directed towards the Swedish-speaking educated class. Both of the newspapers were very popular and their circulations were among the largest of their day in Finland. The topics of his articles and reviews covered literature, poetry, philosophy and education as well as issues concerning the economic, industrial and technical development in Finland. In his newspapers Snellman not only brought forth his own ideas but also spread the knowledge of European events and ideas to his readers. He followed very carefully the cultural and political situation in Western Europe. He also followed European magazines and newspapers and was well acquainted with German, French and also English literature – and of course Swedish literature to with which he had the closest ties. In his newspapers Snellman wrote countless number of literary reviews and critics, introducing his readers to European literature. The study consists of three main chapters in which I explore my research question in three different, yet overlapping contexts. In the first of these chapters, I analyse Snellman’n theoretical thinking and his concepts of bildning, kultur, anda and civilisation in the context of earlier cultural discourse in Finland as well as the tradition of German idealistic philosophy and neo-humanism. With the Finnish cultural discourse I refer to the early cultural discussion in Finland, which emerged after the year 1809, when Finland became an autonomous entity of its own as a Grand Duchy of Russia. Scholars of the Academy of Turku opened a discussion on the themes such as the state of national consciousness, the need for national education and the development of the Finnish language as a national language of Finland. Many of these academics were also Snellman’s teachers in the early years of his academic career and Snellman clearly formulated his own ideas in the footsteps of these Finnish predecessors. In his theoretical thinking Snellman was a collectivist; according to him an individual should always be understood in connection with the society, its values and manners, as well as to the traditions of a culture where an individual belongs to. In his philosophy of the human spirit Snellman was in many ways a Hegelian but his notion of education or ‘bildning’ includes also elements that connect him with the wider tradition of German intellectual history, namely the neo-humanist tradition and, at least to some extent, to the terminology of J. G. Herder or J. G. Fichte, for example. In this chapter, I also explore Snellman’s theory of history. In his historical thinking Snellman was an idealist, believing in the historical development of the human spirit (Geist in German language). One can characterise his theory of history by stating that it is a mixture of a Hegelian triumph of the spirit and Herderian emphasis on humanity (Humanität) and the relative nature of ‘Bildung’. For Snellman, the process of ‘bildning’ or ‘Bildung’ is being realised in historical development through the actions of human beings. Snellman believed in the historical development of the human civilization. Still Snellman himself considered that he had abandoned Hegel’s idea about the process of world history. Snellman – rightly or wrongly – criticised Hegel of emphasising the universal end of history (the realisation of the freedom of spirit) at the expense of the historical plurality and the freedom of each historical era. Snellman accused Hegel of neglecting the value and independency of different historical cultures and periods by imposing the abstract norm, the fulfilment of the freedom of spirit, as the ultimate goal of history. The historicist in Snellman believed in the individuality of each historical period; each historical era or culture had values, traditions and modes of thought of its own. This historicist in Snellman could not accept the talk about one measure or the end of history. On the other hand Snellman was also a universalist. He believed that mankind had a common task and that task was the development of ‘Bildung’, freedom or humanity. The second main chapter consists of two parts. In the first part, I explore the Finnish nationalistic discourse from the cultural point of view by analysing the notions such as a nation, national spirit or national language and showing how Snellman formulated his own ideas in a dialogic situation, participating in the Finnish discourse but also reacting to international discussions on the themes of the nation and nationality. For Snellman nationality was to a great extent the collective knowledge and customs or practices of the nation. Snellman stated that nationality is to be considered as a form of ‘bildning’. This could be seen not simply as affection for the fatherland but also for the mental identity of the nation, its ways of thinking, its practices, national language, customs and laws, the history of the nation. The simplest definition of nationality that Snellman gives is that nationality is the social life of the people. In the second part of the chapter I exam Snellman’s historical thinking and his understanding about historical development, interaction between different nations and cultures in the course of history, as well as the question of historical change; how do cultures or civilisations develop and who are the creators of culture? Snellman did not believe in one dominating culture but understood the course of history as a dialogue between different cultures. On the other hand, his views are very Eurocentric – here he follows the ideas of Hegel or for example the French historian François Guizot – for Snellman Europe represented the virtue of pluralism; in Europe one could see the diversity of cultures which, on the other hand, were fundamentally based on a common Christian tradition. In the third main chapter, my focus is on the writing of history, more precisely on Snellman’s ideas on the nature of history as a science and on the proper way of writing historical presentations. Snellman wrote critics on the works of history and introduced his readers to the writing of history especially in France, Sweden and German-speaking area – in some extend also in Britain. Snellman’s collectivistic view becomes evident also in his reviews on historical writing. For Snellman history was not about the actions of the states and their heads, nor about the records of ruling families and battles fought. He repeatedly stressed that history is a discipline that seeks to provide a total view of a phenomenon. A historian should not only collect information on historical events, since this information touches only the surface of a certain epoch or civilisation; he has to understand an epoch as totality. This required an understanding about the major contours in history, connections between civilisations and an awareness of significant turning points in historical development. In addition, it required a holistic understanding about a certain culture or historical era, including also the so-called inner life of a specific nation, a common people and their ways of life. Snellman wrote explicitly about ‘cultural history’ in his texts, referring to this kind of broad understanding of a society. In historical writing Snellman found this kind of broader view from the works of the French historians such as François Guizot and Jules Michelet. In all of these chapters, I elaborate the conceptual dimension of Snellman’s historical thinking. In my study I argue that Snellman not only adopted the German concepts of Bildung or Kultur in his own thinking but also developed the Swedish concepts in a way that include personal and innovative aspects. Snellman’s concept of bildning is not only a translation from ‘Bildung’ but he uses the Swedish concept in a versatile way that includes both the moral aspect of human development and social dimension of a human life. Along with ‘bildning’ Snellman used also the terms ‘kultur’ and ‘civilisation’ when referring to the totality of a certain nation or historical era, including both the so-called high culture (arts, science, religion) and the modes of thought as well as ways of life of the people as a whole. Unlike many of his Finnish contemporaries, Snellman did not use civilisation as a negative concept, lacking the moral essence of German term ‘Bildung’ or ‘Kultur’. Instead, for Snellman civilisation was a neutral term and here he comes close to the French tradition of using the term. In the study I argue that Snellman’s conception of culture in fact includes a synthesis of the German tradition of ‘Bildung’ and the French tradition of ‘civilisation’.

Hematologic, serum biochemistry and urinary values for captive Crab-eating Fox (Cerdocyon thous) in São Paulo state, Brazil

The importance of studies with hematological, serum biochemistry and urinary values of Crab-eating Fox (Cerdocyon thous) is based on the need for health care and maintenance of those populations. This paper has the objective to investigate hematological, serum biochemistry and urinary physiological parameters of the Crab-eating fox, comparing gender and age differences. Blood samples were collected in 2003 from 52 animals of different Zoos in São Paulo state, Brazil; 7mL of blood was used to obtain a complete blood cell count (CBC) and the profile of the serum biochemistry. Moreover, 5mL of urine were collected for analysis. There was no difference in values for male and female animals, as for the CBC and serum biochemistry. Some hematological and serum biochemical parameters were influenced by age, showing significant differences. Urinalysis results were just demonstrated in a descriptive form. The studied values were, RBC 4.35±0.73 x 10(6) /µL, WBC 7.72±3.66 x 10³ /µL (predominance of segmented neutrophils), platelets 227.06±111.58 x 10³ /µL, urea 43.06±14.28mg/dL and creatinine 1.03±0.24mg/dL. Hematological, serum biochemistry and urinary values obtained in this study can be used as physiological values of the captive Crab-eating Fox. It is possible to conclude that wild species need their own reference values, differentiating animals in captivity from free-ranging animals.

Hematology values of captive giant anteaters (Myrmecophaga tridactyla) and collared anteaters (Tamandua tetradactyla)

Hematological results are reported for 13 giant anteaters (Myrmecophaga tridactyla) and 13 collared anteaters (Tamandua tetradactyla). Animals were captive-reared adults held at the Fundação Parque Zoológico de São Paulo (São Paulo, SP, Brazil) and Parque Zoológico Municipal Quinzinho de Barros (Sorocaba, SP, Brazil), and were considered healthy on physical examination. Examined parameters included red blood cell count, white blood cell count, hematocrit, hemoglobin concentration, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, total plasmatic protein and differential leukocyte counts. Also, a survey for hemoparasites was done and none was observed in thin blood smears. The results were generally similar to those previously reported in the exiguous literature for these species, providing further reference data for the interpretation of laboratory results besides health monitoring, assisting early disease diagnosis and providing relevant information for conservation programs for these species.

Das persönliche Glück auf dem unpersönlichen Markt. Deutsche und finnische Kontaktanzeigen im 20. Jahrhundert - eine kontrastive und diachrone Textsortenuntersuchung

Min avhandling är en diakronisk och kontrastiv undersökning av texttyper. Forskningsmaterialet består av kontaktannonser i tidningarna Süddeutsche Zeitung och Helsingin Sanomat under tiden 1900 – 1999. Materialet består av 652 tyska och 538 finska annonser. De undersökta annonserna har publicerats i maj och har samlats från ovannämnda tidningar vart tionde år. Materialet har analyserats med ett statistiskt SPSS-program. I avhandlingen analyseras utvecklingen av ovannämnda texttyp under hundra år i två olika kulturer, den tyska och den finska. Syftet med avhandlingen är att med hjälp av detta material finna språkliga och kulturella likheter och skillnader i kontaktannonser. Utgångspunkten är att språkliga uttryck avspeglar sin tids samhälleliga värderingar, vilka således också påverkar sökandet efter en livskamrat. Analysresultaten granskas sålunda i ett större samhälleligt sammanhang under olika decennier. Annonstexterna undersöks dock inte utgående från enskilda samhälleliga skeenden. Avhandlingen analyserar 13 olika informationsenheter i kontaktannonserna, huruvida dessa enheter förekommer under hela den aktuella perioden och om samma informationsenheter förekommer i annonser i de båda kulturerna. Avhandlingen är sålunda intra- och interlingual samt interkulturell. Genom denna metod får man fram de kännetecken som är betecknande för denna texttyp under en viss tid i de bägge kulturerna. Avhandlingen är indelad i tre delar. Den första delen ger bakgrundsinformation om äktenskapets och familjebegreppets historia samt om uppkomsten av den tyska och finska pressen. Den andra teoretiska delen behandlar text- och texttyplingvistik samt nuvarande forskning inom dessa områden. Den tredje och mest omfattade delen består av en kvalitativ och kvantitativ analys, som omfattar 11 olika forskningsdelar. Undersökningen visar att man i texttypen kontaktannonser kan upptäcka skillnader t ex redan däri att en tysk annons skiljer sig från en finsk vad längd och informationsmängd beträffar. En finsk annons förlitar sig i sin språkliga knapphet på att läsaren förstår kontexten i texttypen. Av avhandlingen framgår också att vid analys av texttyper bör deras historiska och kulturella kontext beaktas, eftersom analysen påvisar att texttyperna är historie- och kulturbundna.

”Du sköna sång, vårt bästa arv” - kanonisering av en sångskatt ur ett hermeneutiskt perspektiv

Songs have the power to get through to people. When lyrics are combined with a tune, the result is an entity where the first few notes of a melody can evoke emotions of recognition and belonging. A song treasury consists of such songs that are part of a canonized song tradition. The process where certain songs become part of an established song treasury is long, and many other aspects than the tune itself influence the forming of a song treasury. By examining the characteristics of a song tradition, the history of an ethnic group can be illuminated. In this study, music, pedagogy, and the sociocultural context are merged into a whole where a common song tradition, the song treasury, is in focus. The main aim of this study is to deepen the understanding of a song treasury, its development and contents. This understanding is accomplished by analyzing the musical and lyrical characteristics of 60 songs, which have been sung in schools, homes, and communities, thereby becoming popular among the Swedish-speaking Finns during the 20th century. The songs have been chosen by combining three song lists, of which two lists are closely related to school curricula. The third song list is a result of a survey on favourite songs, according to the situation around year 2000. The songs are examined in their notated versions, a number of song books and text books (n = 29) forming the empirical material. In this study, a hermeneutical approach is applied, content analysis being the method. The analysis is based on three perspectives: the sociocultural perspective, the music-pedagogical perspective, and the musico-analytical perspective. Within each perspective, two aspects are studied. This results in a hexagonal model which forms the structure of the study as a whole. The first two perspectives form the background; a historical context where nation, education, home country, and homestead are regarded as highly important. A common song repertoire is considered to be an effective means of building collective identity within ethnic groups, the common language and the cultural heritage being used as rhetorical arguments. During the early 1900s, choir festivals become an educational platform where conceptions of a common belonging are developed and strengthened through religious, patriotic, and poetical expressions. National school curricula in singing and music have similar characteristics, cultural heritage and values education being in focus. The song lyrics often describe nature and emotions, and they also appear to be personal and situated in a given time and place. Patriotic expressions and songs about music are also fairly common. The songs generally express positive attitudes, which are intensified by major tonality, rich and varied melodies with stable rhythms, and a strong tonal base. The analyzed details of the studied aspects are merged into a thick description, which results in an interpretation pattern with three dimensions: a song treasury can be considered an expression of collective identity, cultural heritage, and values education.
