Kirjan tie lukijalle : Kirjakauppojen vakiintuminen Suomessa 1740 - 1860

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.

Herrana metsässä : Kansatieteellinen tutkimus metsänhoitajuudesta

The aim of the research is to interpret the professional culture of Finnish university-educated foresters in historical perspective. The main material of this research consists of biographical interviews, altogether 226 life stories of Finnish foresters, as well as foresters private photograph collections and articles in forest students' magazines. This study is the first published Ph. D. dissertation of a large oral history project "Forestry Professions in a Changing Society" 1999 2002 collected by The Finnish Forest History Society, the University of Helsinki (Ethnology) and The Finnish Forest Museum Lusto. The forester education was organized in the Evo Forest Institute 1862 1908, at the University of Helsinki since 1908 and additionally at the University of Joensuu since 1982. At first all the vacancies were in the service of the Board of Forestry, but during the 20th century the working opportunities of foresters significantly expanded, even outside the traditional areas of forestry or abroad. At the same time the whole area of Finnish forestry had integrated more versatile values concerning the forests and their use. The male-dominated profession gained its first female members already in the 1920s, and the number of female students rose gradually from the 1970s onwards. In the 1990s almost half of the new forest students were women. The content of both work and education of Finnish forest professionals has faced huge changes during the 19th and 20th centuries. Despite this however, there has been a long-term vision of a firm profession based on joint experiences, shared memories and the common task of foresters in the Finnish forestry. The feeling of togetherness the forester spirit which was created in a tight-knit student group which kept in touch also later as professionals was needed to make the work possible. Through foresters' own attitudes and narratives of themselves, the study is focused on forest professionalism as a cultural process of successive generations of foresters. How have foresters socialized themselves into their profession? How has forest professionalism been maintained? What is the meaning of joint experiences and shared memories in the profession? By studying the manifestations of a culture it is possible to interpret the culture itself. There seems to be an astounding consensus of opinion concerning forest professionalism in the oral, visual and written stories of foresters. Even if all the individuals and some separate groups, such as female foresters and the younger generation of foresters, did not always share the same experiences, the vision of forest professionalism was collectively recognized and often even approved. The shared idea of "a real forest professionalism" is like a model narrative, a point of comparison, which is needed while looking for one s own professional identity.

Stone Weathering in the Monastic Building Complex on Mountain of St Aaron in Petra, Jordan.

Since 1997 the Finnish Jabal Haroun Project (FJHP) has studied the ruins of the monastery and pilgrimage complex (Gr. oikos) of Aaron located on a plateau of the Mountain of Prophet Aaron, Jabal an-Nabi Harûn, ca. 5 km to the south-west of the UNESCO World Heritage site of Petra in Jordan. The state of conservation and the damaging processes affecting the stone structures of the site are studied in this M.A. thesis. The chapel was chosen as an example, as it represents the phasing and building materials of the entire site. The aim of this work is to act as a preliminary study with regards to the planning of long-term conservation at the site. The research is empirical in nature. The condition of the stones in the chapel walls was mapped using the Illustrated Glossary on Stone Deterioration, by the ICOMOS International Scientific Committee for Stone. This glossary combines several standards and systems of damage mapping used in the field. Climatic conditions (temperature and RH %) were monitored for one year (9/2005-8/2006) using a HOBO Microstation datalogger. The measurements were compared with contemporary measurements from the nearest weather station in Wadi Musa. Salts in the stones were studied by taking samples from the stone surfaces by scraping and with the “Paper Pulp”-method; with a poultice of wet cellulose fiber (Arbocel BC1000) and analyzing what main types of salts were to be found in the samples. The climatic conditions on the mountain were expected to be rapidly changing and to differ clearly from conditions in the neighboring areas. The rapid changes were confirmed, but the values did not differ as much as expected from those nearby: the 12 months monitored had average temperatures and were somewhat drier than average. Earlier research in the area has shown that the geological properties of the stone material influence its deterioration. The damage mapping showed clearly, that salts are also a major reason for stone weathering. The salt samples contained several salt combinations, whose behavior in the extremely unstable climatic conditions is difficult to predict. Detailed mapping and regular monitoring of especially the structures, that are going remain exposed, is recommended in this work.

"You must trust somebody" : Valtio, liberalismi ja sotatarviketeollisuus Britanniassa 1884-1905

Tutkielmassa on tarkasteltu Britannian sotilasviranomaisten ja maan sotatarviketeollisuuden välisiä suhteita vuosina 1884-1905. Kiihtyvän kilpavarustelun myötä Britannian sotilasbudjetit kasvoivat nopeasti, mikä johti maan sotatarviketeollisuuden saamien tilausten määrän nopeaan kasvuun samalla kun tuotteiden teknologinen kehitys oli nopeaa. Sotilasmenojen nopea kasvu antoi sotamateriaalihankinnoista vastaaville viranomaisille mahdollisuuden vaikuttaa yksityisen teollisuuden kehitykseen. Keskittämällä tilaukset vain luotettavina pitämilleen yrityksille viranomaiset loivat näiden kanssa puolivirallisia yhteistyösuhteita ja edistivät samalla voimakkaasti alan keskittymistä. Toisaalta muutamien suuryritysten hallitsemasta sotatarviketuotannosta muodostui yksi niistä harvoista teollisuuden aloista, joilla Britannian nopeasti kasvavat kilpailijat eivät pystyneet ohittamaan sitä enempää tuotteiden teknologisessa tasossa kuin markkinaosuuksien suuruudessakaan. Tiettyjen yritysten suosimisen taustalla ei ollut vain maanpuolustuksen kannalta rationaalinen pyrkimys hankkia riittävän laadukasta ja kehittynyttä sotamateriaalia, vaan asiaan vaikutti myös upseerien ja sotilasministeriöiden siviilivirkamiesten perinteiset aristokraattiset ajattelu- ja toimintamallit. Taloudellisen liberalismin hengessä tapahtuneet pyrkimykset uudistaa hankintamenettelyä vastaamaan enemmän vapaan kilpailun ja taloudellisuuden ihanteita j��ivät yleensä tuloksettomiksi. Sotamateriaalihankintoihin liittyvä päätöksenteko vaati suurta asiantuntemusta, mikä johti sotaministeriön ja amiraliteetin virkamiesten vaikutusvallan kasvamiseen. Sotateollisuuden laajeneminen kytkeytyy läheisesti 1900-luvun alussa Britannian yhteiskunnallisessa elämässä tapahtuneeseen muutokseen, jota yleensä on luonnehdittu laissez fairen lopuksi. Jo 1880-luvulla alkaneella puuttumisellaan yksityisten sotateollisuusyritysten kehitykseen viranomaiset olivat alkaneet harjoittaa suunniteltua teollisuuspolitiikkaa, jonka tuloksena syntynyt puolivirallinen sotilasteollinen sektori oli aatteellisesti liberaaliin yhteiskuntaan soveltumaton ilmiö. Aseteollisuudessa Britannian valtio oli siten joutunut ensimmäisen kerran läheiseen vuorovaikutussuhteeseen modernien suuryritysten kanssa. Kytkentä, joka 1900-luvun kuluessa levisi yhä uusille aloille samalla kun valtion roolia talouselämässä alettiin vahvistaa. Tutkimuksen varsinaisen lähdemateriaalin muodostavat Britannian parlamentin pöytäkirjat ja sen komiteoiden raportit Niiden ohella on käytetty päätöksien tekemiseen osallistuneiden tai niihin vaikuttamiseen pyrkineiden poliitikkojen ja sotilaiden painettuja puheita, kirjekokoelmia, päiväkirjoja ja muistelmia sekä eräitä aikakauden historiaa koskevia dokumenttikokoelmia ja tilastojulkaisuja. Oleellista valaistusta asiaan tuovat osaltaan aikalaisten kirjoittamat teokset sekä lehdistö, joista kuvastuu ajalle ominainen ajattelutapa. Aihetta suoranaisesti koskevaa, tieteellisen tutkimusten kriteerit täyttävää aikaisempaa tutkimusta on vähän, mutta aihetta sivuavien tutkimusten määrä on erittäin suuri. Sotamateriaalihankintoja ja niiden taustalla olevia syitä voidaan tarkastella niin talous-, sota- aate-, kuin poliittisen historiankin näkökulmista, mutta yksinään mikään niistä ei ole riittävä tämän tutkimuksen kysymyksenasettelun kannalta. Siten tutkielmaa varten on perehdytty laajasti aikakautta koskevaan tutkimuskirjallisuuteen.

Isolation and expression analysis of multiple isoforms of putative farnesoic acid O-methyltransferase in several crustacean species

Farnesoic acid O-methyltransferase (FaMeT) is the enzyme responsible for the conversion of farnesoic acid (FA) to methyl farnesoate (MF) in the final step of MF synthesis. Multiple isoforms of putative FaMeT were isolated from six crustacean species belonging to the families Portunidae, Penaeidae, Scyllaridae and Parastacidae. The portunid crabs Portunus pelagicus and Scylla serrata code for three forms: short, intermediate and long. Two isoforms (short and long) were isolated from the penaeid prawns Penaeus monodon and Fenneropenaeus merguiensis. Two isoforms were also identified in the scyllarid Thenus orientalis and parastacid Cherax quadricarinatus. Putative FaMeT sequences were also amplified from the genomic DNA of P. pelagicus and compared to the putative FaMeT transcripts expressed. Each putative FaMeT cDNA isoform was represented in the genomic DNA, indicative of a multi-gene family. Various tissues from P. pelagicus were individually screened for putative FaMeT expression using PCR and fragment analysis. Each tissue type expressed all three isoforms of putative FaMeT irrespective of sex or moult stage. Protein domain analysis revealed the presence of a deduced casein kinase II phosphorylation site present only in the long isoform of putative FaMeT.

Vapaata mielenjuoksua : Suomenkielisen freestyle-rapin ilmenemismuodot, estetiikka ja kompositio

The thesis is about Finnish freestyle-rap, a modern form of oral poetry producing improvised rap lyrics at the moment of performance. The research material consists of interviews with seven freestyle experts and a DVD from Finnish Rap Championships 2005 containing freestyle-rap. The thesis has three goals: describing the different variations or subgenres of freestyle, outlining the esthetics and register of freestyle, and examining the composition of freestyle. The research material acts a central role in the thesis but the theoretical framework is also wide: cornerstones are John Miles Foley's register analysis, oral formulaic theory and William Levelt's psycholinguistic theory on planning of speech. Freestyle is divided into three partially overlapping genres with slight variation in conventions. The genres are freestyle battle, cypher, and live freestyle. Freestyle's esthetics are composed of certain qualities and preferences: the rhyme is a syllabically repeating vocal rhyme. The rapping must be synchronised with the background rhythm and the rhyme comes in the end of the line. The lyrics must be somehow anchored to the surroundings and the moment of performance. The style of rapping, ie. flow, has to be personal one way or the other. Individual formulas are used to some extent in freestyle compostition. When planning the lines, all other content is subordinate to the rhyme, whose phonetic processing is the primary act in the planning of freestyle. This discovery sets Levelt's theory open to doubt.

Radical nursing and the emergence of technique as healthcare technology

The integration of technology in care is core business in nursing and this role requires that we must understand and use technology informed by evidence that goes much deeper and broader than actions and behaviours. We need to delve more deeply into its complexity because there is nothing minor or insignificant about technology as a major influence in healthcare outcomes and experiences. Evidence is needed that addresses technology and nursing from perspectives that examine the effects of technology, especially related to increasing demands for efficiency, the relationship of technology to nursing and caring, and a range of philosophical questions associated with empowering people in their healthcare choices. Specifically, there is a need to confront in practice the ways technique influences care. Technique is the creation of a kind of thinking that is necessary for contemporary healthcare technology to develop and be applied in an efficient and rational manner. Technique is not an entity or specific thing, but rather a way of thinking that seeks to shape and organize nursing activity, and manage efficiently individual difference(s) in care. It emphasizes predetermined causal relationships, conformity, and sameness of product, process, and thought. In response is needed a radical vision of nursing that attempts in a real sense to ensure we meet the needs of individuals and their community. Activism and advocacy are needed, and a willingness to create a certain detachment from the imperatives that technique demands. It is argued that our responsibility as nurses is to respond in practice to the errors, advantages, difficulties, and temptations of technology for the benefit of those who most need our assistance and care.

Lausunta taiteena ja tapahtumana : Tekstikeskeisyys, esittäj��keskeisyys ja lausunnan positiot lausuntaa koskevan kirjallisen aineiston ja teatterintutkimuksen viitekehyksessä

The research is analyzing the Finnish tradition on poetry elocution both from the discource analytical and theatrical and view point. The main questions are, whether there still is a fixed position for elocution in the field of art or are we dealing with just one form of thearte? -- The art of elocution has been considered as an independent art form, sometimes even in opposition to theatre, which has been regarded as a very physical and emotional art form by the elocutionists themselves. The self-image of the Finnish elocution art has been born and firmly sustained from the notion that elocution is linked to literature. Elocution as an art form has been seen as "pure" and humbly serving literature and poetry. The main function of an elocutionist has been to understand and vocally express the meanings found in a poem to larger audience. -- This function has changed over the time. There have been a transition from the traditonal text-centeredness to performer-centeredness, even to performance-centeredness as a new wave of theatrical elements and methods have reached the circle of elocution. New forms of poetry performances, such as poetry reading and poetry slam are new challenges to elocution as it must reconsider it´s traditional function in a new artistic and cultural context.

On Toponymic Constructions as an Alternative to Naming Patterns in Describing Finnish Lake Names

This thesis combines a computational analysis of a comprehensive corpus of Finnish lake names with a theoretical background in cognitive linguistics. The combination results on the one hand in a description of the toponymic system and the processes involved in analogy-based naming and on the other hand some adjustments to Construction Grammar. Finnish lake names are suitable for this kind of study, as they are to a large extent semantically transparent even when relatively old. There is also a large number of them, and they are comprehensively collected in a computer database. The current work starts with an exploratory computational analysis of co-location patterns between different lake names. Such an analysis makes it possible to assess the importance of analogy and patterns in naming. Prior research has suggested that analogy plays an important role, often also in cases where there are other motivations for the name, and the current study confirms this. However, it also appears that naming patterns are very fuzzy and that their nature is somewhat hard to define in an essentially structuralist tradition. In describing toponymic structure and the processes involved in naming, cognitive linguistics presents itself as a promising theoretical basis. The descriptive formalism of Construction Grammar seems especially well suited for the task. However, now productivity becomes a problem: it is not nearly as clear-cut as the latter theory often assumes, and this is even more apparent in names than in more traditional linguistic material. The varying degree of productivity is most naturally described by a prototype-based theory. Such an approach, however, requires some adjustments to onstruction Grammar. Based on all this, the thesis proposes a descriptive model where a new name -- or more generally, a new linguistic expression -- can be formed by conceptual integration from either a single prior example or a construction generalised from a number of different prior ones. The new model accounts nicely for various aspects of naming that are problematic for the traditional description based on analogy and patterns.

Thomsenista Kalimaan : Vanhimpien itämerensuomalais-balttilaisten kielikontaktien tutkimushistoria vuoteen 1936

Itämerensuomalaisissa kielissä esiintyy suuri joukko sanoja, jotka muistuttavat balttilaisten kielten sanoja sekä muotonsa että merkityksensä puolesta. Yhtäläisyyksiä oli yritetty selittää eri tavoin 1700-luvulta lähtien, kunnes Vilhelm Thomsen vuonna 1869 osoitti tämän sanastokerrostuman olevan lainaa jostakin muinaisbalttilaisesta kielimuodosta nykyisten itämerensuomalaisten kielten yhteiseen kantakieleen. Vuonna 1890 Thomsen julkaisi aiheesta laajemman tutkimuksen, jossa hän esitti noin 200 muinaisbalttilaista lainaetymologiaa ja käsitteli lainojen äännevastaavuuksia sekä kielellisten kontaktien paikkaa, aikakautta ja kulttuurikontekstia. Nykykäsitys itämerensuomalaisten kielten vanhoista balttilaisista lainasanoista perustuu tähän Thomsenin esitykseen, ainoastaan kontaktien ajoituksia on arkeologian tulosten myötä siirretty taaksepäin. Thomsen sovelsi ensimmäisenä suomalais-ugrilaisten kielten tutkimukseen aikakautensa uusinta kielitieteellistä metodia, nuorgrammatiikkaa. Nuorgrammatiikka keskittyi kielihistoriaan ja antoi eksaktit välineet etymologialle. Suomeen nuorgrammatiikan toi E. N. Setälä, jonka johdolla metodi uudisti nopeasti koko fennougristiikan ja nosti Suomen tutkimuksen kärkeen. Suomalaistutkijat tarkensivat myös Thomsenin luomaa kuvaa vanhoista balttilaisista lainoista. Setälän ohella keskeisiä etymologeja olivat J. J. Mikkola ja Heikki Paasonen. Muualla tutkimus ei ollut yhtä intensiivistä: vain liettualainen Kazimieras Būga perehtyi mainittavasti aiheeseen, ja hänenkin tutkijan uransa j��i lyhyeksi. Vasta 1910-luvun puolessa välissä Thomsenin ja Setälän teesej�� alettiin kritikoida. Torsten Karsten ja K. B. Wiklund esittivät vanhimmille balttilaiskontakteille paljon kauemmas menneisyyteen ulottuvia ajoituksia kuin Thomsen. Setälän auktoriteetti kuitenkin torjui uudet teoriat, jotka on vasta paljon myöhemmin yleisesti hyväksytty. Sotien välinen kausi oli erittäin vilkkaan etymologisen tutkimuksen aikaa, ja balttilaisiakin lainoja esitettiin kymmeniä lisää. Ajan uutterimmat tutkijat olivat Heikki Ojansuu, Yrj�� Toivonen ja Jalo Kalima. Luonnollisesti myös monet Thomsenin balttilaiset etymologiat korvattiin paremmin sopivilla lainaetymologioilla tai rinnastuksilla sukukielistä. Mikkola arvosteli hyvin voimakkaasti Thomsenin lainaetymologioita. Mikkolan kritiikki osoittautui pääosin pätemättömäksi, mutta on päässyt epäsuorasti vaikuttamaan myöhempään tutkimukseen. Eino Nieminen taas esitti vuonna 1934 hypoteesin, jonka mukaan ainakin osa vanhoista balttilaislainoista voisi olla peräisin muinaiskuurin kielestä, jota baltologit olivat parin vuosikymmenen ajan pyrkineet rekonstruoimaan. Jalo Kalima julkaisi vuonna 1936 oppikirjan itämerensuomalaisten kielten vanhoista balttilaislainoista. Kalima pyrki antamaan kattavan kuvan aiheesta, mutta ei onnistunut kovin hyvin. Kaliman tiedot balttilaisista kielistä eivät olleet ajan tutkimuksen tasolla, ja hän j��tti kirjassansa käsittelemättä suuren osan uudempaa tutkimusta, mm. Thomsenin ajoituksia kohtaan osoitetun kritiikin sekä kymmenittäin niin Thomsenin kuin myöhempienkin tutkijoitten esittämiä etymologioita. Kaliman kirja on kuitenkin selkeästi laadittu ja sisältää uusia, ansiokkaitakin etymologioita. Kaliman j��lkeen kukaan ei ole kirjoittanut yleisesitystä aiheesta. Tämän tutkielman tavoite on antaa kattava kuva vanhimpien itämerensuomalais-balttilaisten kielikontaktien tutkimuksesta ennen Kaliman oppikirjaa. Näin se voisi tasoittaa tietä uudelle alan yleisesitykselle.

Diet quality and liveweight gain of steers grazing Leucaena-grass pasture estimated with faecal near infrared reflectance spectroscopy (F.NIRS)

Three drafts of Bos indicus cross steers (initially 178-216 kg) grazed Leucaena-grass pasture [Leucaena leucocephala subspecies glabrata cv. Cunningham with green panic (Panicum maximum cv. trichoglume)] from late winter through to autumn during three consecutive years in the Burnett region of south-east Queensland. Measured daily weight gain (DWGActual) of the steers was generally 0.7-1.1 kg/day during the summer months. Estimated intakes of metabolisable energy and dry matter (DM) were calculated from feeding standards as the intakes required by the steers to grow at the DWGActual. Diet attributes were predicted from near infrared reflectance spectroscopy spectra of faeces (F.NIRS) using established calibration equations appropriate for northern Australian forages. Inclusion of some additional reference samples from cattle consuming Leucaena diets into F.NIRS calibrations based on grass and herbaceous legume-grass pastures improved prediction of the proportion of Leucaena in the diet. Mahalanobis distance values supported the hypothesis that the F.NIRS predictions of diet crude protein concentration and DM digestibility (DMD) were acceptable. F.NIRS indicated that the percentage of Leucaena in the diet varied widely (10-99%). Diet crude protein concentration and DMD were usually high, averaging 12.4 and 62%, respectively, and were related asymptotically to the percentage of Leucaena in the diet (R2 = 0.48 and 0.33, respectively). F.NIRS calibrations for DWG were not satisfactory to predict this variable from an individual faecal sample since the s.e. of prediction were 0.33-0.40 kg/day. Cumulative steer liveweight (LW) predicted from F.NIRS DWG calibrations, which had been previously developed with tropical grass and grass-herbaceous legume pastures, greatly overestimated the measured steer LW; therefore, these calibrations were not useful. Cumulative steer LW predicted from a modified F.NIRS DWG calibration, which included data from the present study, was strongly correlated (R2 = 0.95) with steer LW but overestimated LW by 19-31 kg after 8 months. Additional reference data are needed to develop robust F.NIRS calibrations to encompass the diversity of Leucaena pastures of northern Australia. In conclusion, the experiment demonstrated that F.NIRS could improve understanding of diet quality and nutrient intake of cattle grazing Leucaena-grass pasture, and the relationships between nutrient supply and cattle growth.

Side Chain Structure Determines Unique Physiologic and Therapeutic Properties of norUrsodeoxycholic Acid in Mdr2(-/-) Mice

24-norursodeoxycholic acid (norUDCA), a side chain-modified ursodeoxycholic acid derivative, has dramatic therapeutic effects in experimental cholestasis and may be a promising agent for the treatment of cholestatic liver diseases. We aimed to better understand the physiologic and therapeutic properties of norUDCA and to test if they are related to its side chain length and/or relative resistance to amidation. For this purpose, Mdr2-/- mice, a model for sclerosing cholangitis, received either a standard diet or a norUDCA-, tauro norursodeoxycholic acid (tauro- norUDCA)-, or di norursodeoxycholic acid (di norUDCA)-enriched diet. Bile composition, serum biochemistry, liver histology, fibrosis, and expression of key detoxification and transport systems were investigated. Direct choleretic effects were addressed in isolated bile duct units. The role of Cftr for norUDCA-induced choleresis was explored in Cftr-/- mice. norUDCA had pharmacologic features that were not shared by its derivatives, including the increase in hepatic and serum bile acid levels and a strong stimulation of biliary HCO3- -output. norUDCA directly stimulated fluid secretion in isolated bile duct units in a HCO3- -dependent fashion to a higher extent than the other bile acids. Notably, the norUDCA significantly stimulated HCO 3- -output also in Cftr-/- mice. In Mdr2-/- mice, cholangitis and fibrosis strongly improved with norUDCA, remained unchanged with tauro- norUDCA, and worsened with di norUDCA. Expression of Mrp4, Cyp2b10, and Sult2a1 was increased by norUDCA and di norUDCA, but was unaffected by tauro- norUDCA. Conclusion:The relative resistance of norUDCA to amidation may explain its unique physiologic and pharmacologic properties. These include the ability to undergo cholehepatic shunting and to directly stimulate cholangiocyte secretion, both resulting in a HCO3- -rich hypercholeresis that protects the liver from cholestatic injury.

Käsityksistä ajatuksen poluille : Ammattikorkeakoulun tutkimus- ja kehitystoiminnan kehittäminen

This study deals with the formation of the idea of research and development (r&d) activity at one particular university of applied sciences in Finland. In this study I proceed from examining the conceptions of management regarding r&d-activities to exploring the development of the complex concept that guides these r&d-activities. The aim of this study is, first, to describe conceptions of r&d-activities, and then, second, to describe the formation of a new concept for r&d-activities in one field of study at the university of applied sciences. I used phenomenographic analysis to elucidate the conceptions and collected the data in interviews of personnel (22) who belong to the management of the university of applied sciences. The data for analysing the obstacles faced and the ways of overcoming them during the formation process of the new concept consist of the video-recorded material from ten change laboratory sessions held for the specific field of study at the university of applied sciences. In researching the formation of the concept of the activity, such research and analysis methods are used in which the concept is understood as a material construction, and with the help of which one can work out the formation of the concept during the development process. When the systematic development of the r&d-work was underway, the management of the university of applied sciences held differing views regarding the content, target, factors and organisation of the r&d-activities, as well as regarding the position of dissertations as a part of r&d-activity. Obstacles for developing rd concerned the unclear object and outcomes of the new activity, not having the tools (such as adequate know-how) for the new activity and not having found the necessary solutions for the distribution of work. In addition the rules that quide the activities of the university of applied sciences did not support working according to the new way. To improve r&d-activity, the school’s management defined three development strategies to encourage adequate rd-activity to support working life, regional development and learning. The strategies were based on the expansion of existing methods, such as service activities, dissertation work and the research activities of the teachers. Of the three possible routes, the concept of dissertation in this study was expanded to integrate the services of organisation development and the occupational growth of the students. A group of teachers in the field of social and health studies participated in the development work. The change laboratory method was used as a tool for this work. Analysis of the cognitive trails indicated that, in addition to the cycle of expansive learning activities, microcycles with different purposes can exist. According to Cussins (1992), something already in existence in each microcycle is destabilised, and something else is stabilised to replace it. In this study three microcycles were identified, during which the teachers first destabilised the existing concepts of dissertation work that guided their thinking, and then began to use new concepts to structure their thinking. Secondly, they undermined the existing concepts with material structure that defined their practical work, and developed new practical models to replace them. Thirdly, the problems accumulating in researching and testing the new activities caused the developers to destabilise the r&d-strategies of the university of applied sciences and to define a new conceptual model for r&d-work in the field. During this third cycle, the teachers developed a research arena model, which was a significant expansive innovation. In the cognitive trails developing the new concept for the r&d-activity, the teachers indeed faced the obstacles the management had described as their conceptions. These obstacles manifested themselves as contradictions. During the development process, the nature of the obstacles (i.e. contradictions) changed as the development proceeded. Solving the first and second degree contradictions highlighted the third and fourth degree contradictions. To overcome the obstacles, the teachers had to to articulate the value and motive of the development work throughout the development process. Developing the new concept for r&d-activity required many reconfigurations of practical solutions to overcome the obstacles. Developing the new concept for r&d-activity, both at the level of representations and of new practices, requires universities of applied sciences to adopt new methods in which the actors are partake in construction of new concepts of activity through adequate discussion, analysis and debate. R&d -activity can progress, if instead of implementing partial solutions, the totality of the activities (i.e. the group of partial solutions acting together) will be constructed. The development of the activity system requires many simultaneous changes as well as wide-ranging know-how and discussion related to these changes. What is perhaps most important, however, is that the group of developers mature into a determined collective actor which can engage in many agentive actions. The development of the agency is fundamental to progress.

Exploring Problem Decomposition in Conceptual Design

Design embraces several disciplines dedicated to the production of artifacts and services. These disciplines are quite independent and only recently has psychological interest focused on them. Nowadays, the psychological theories of design, also called design cognition literature, describe the design process from the information processing viewpoint. These models co-exist with the normative standards of how designs should be crafted. In many places there are concrete discrepancies between these two in a way that resembles the differences between the actual and ideal decision-making. This study aimed to explore the possible difference related to problem decomposition. Decomposition is a standard component of human problem-solving models and is also included in the normative models of design. The idea of decomposition is to focus on a single aspect of the problem at a time. Despite its significance, the nature of decomposition in conceptual design is poorly understood and has only been preliminary investigated. This study addressed the status of decomposition in conceptual design of products using protocol analysis. Previous empirical investigations have argued that there are implicit and explicit decomposition, but have not provided a theoretical basis for these two. Therefore, the current research began by reviewing the problem solving and design literature and then composing a cognitive model of the solution search of conceptual design. The result is a synthetic view which describes recognition and decomposition as the basic schemata for conceptual design. A psychological experiment was conducted to explore decomposition. In the test, sixteen (N=16) senior students of mechanical engineering created concepts for two alternative tasks. The concurrent think-aloud method and protocol analysis were used to study decomposition. The results showed that despite the emphasis on decomposition in the formal education, only few designers (N=3) used decomposition explicitly and spontaneously in the presented tasks, although the designers in general applied a top-down control strategy. Instead, inferring from the use of structured strategies, the designers always relied on implicit decomposition. These results confirm the initial observations found in the literature, but they also suggest that decomposition should be investigated further. In the future, the benefits and possibilities of explicit decomposition should be considered along with the cognitive mechanisms behind decomposition. After that, the current results could be reinterpreted.

Nonlinear transport in semiconducting polymers at high carrier densities

Conducting and semiconducting polymers are important materials in the development of printed, flexible, large-area electronics such as flat-panel displays and photovoltaic cells. There has been rapid progress in developing conjugated polymers with high transport mobility required for high-performance field-effect transistors (FETs), beginning(1) with mobilities around 10(-4) cm(2) V-1 s(-1) to a recent report(2) of 1 cm(2) V-1 s(-1) for poly(2,5-bis(3-tetradecylthiophen-2-yl) thieno[3,2-b] thiophene) (PBTTT). Here, the electrical properties of PBTTT are studied at high charge densities both as the semiconductor layer in FETs and in electrochemically doped films to determine the transport mechanism. We show that data obtained using a wide range of parameters (temperature, gate-induced carrier density, source-drain voltage and doping level) scale onto the universal curve predicted for transport in the Luttinger liquid description of the one-dimensional `metal'.
