Talking About Time in Russian and Finnish

In this study I look at what people want to express when they talk about time in Russian and Finnish, and why they use the means they use. The material consists of expressions of time: 1087 from Russian and 1141 from Finnish. They have been collected from dictionaries, usage guides, corpora, and the Internet. An expression means here an idiomatic set of words in a preset form, a collocation or construction. They are studied as lexical entities, without a context, and analysed and categorized according to various features. The theoretical background for the study includes two completely different approaches. Functional Syntax is used in order to find out what general meanings the speaker wishes to convey when talking about time and how these meanings are expressed in specific languages. Conceptual metaphor theory is used for explaining why the expressions are as they are, i.e. what kind of conceptual metaphors (transfers from one conceptual domain to another) they include. The study has resulted in a grammatically glossed list of time expressions in Russian and Finnish, a list of 56 general meanings involved in these time expressions and an account of the means (constructions) that these languages have for expressing the general meanings defined. It also includes an analysis of conceptual metaphors behind the expressions. The general meanings involved turned out to revolve around expressing duration, point in time, period of time, frequency, sequence, passing of time, suitable time and the right time, life as time, limitedness of time, and some other notions having less obvious semantic relations to the others. Conceptual metaphor analysis of the material has shown that time is conceptualized in Russian and Finnish according to the metaphors Time Is Space (Time Is Container, Time Has Direction, Time Is Cycle, and the Time Line Metaphor), Time Is Resource (and its submapping Time Is Substance), Time Is Actor; and some characteristics are added to these conceptualizations with the help of the secondary metaphors Time Is Nature and Time Is Life. The limits between different conceptual metaphors and the connections these metaphors have with one another are looked at with the help of the theory of conceptual integration (the blending theory) and its schemas. The results of the study show that although Russian and Finnish are typologically different, they are very similar both in the needs of expression their speakers have concerning time, and in the conceptualizations behind expressing time. This study introduces both theoretical and methodological novelties in the nature of material used, in developing empirical methodology for conceptual metaphor studies, in the exactness of defining the limits of different conceptual metaphors, and in seeking unity among the different facets of time. Keywords: time, metaphor, time expression, idiom, conceptual metaphor theory, functional syntax, blending theory

Microbial diversity in the municipal composting process and development of detection methods

Composting refers to aerobic degradation of organic material and is one of the main waste treatment methods used in Finland for treating separated organic waste. The composting process allows converting organic waste to a humus-like end product which can be used to increase the organic matter in agricultural soils, in gardening, or in landscaping. Microbes play a key role as degraders during the composting-process, and the microbiology of composting has been studied for decades, but there are still open questions regarding the microbiota in industrial composting processes. It is known that with the traditional, culturing-based methods only a small fraction, below 1%, of the species in a sample is normally detected. In recent years an immense diversity of bacteria, fungi and archaea has been found to occupy many different environments. Therefore the methods of characterising microbes constantly need to be developed further. In this thesis the presence of fungi and bacteria in full-scale and pilot-scale composting processes was characterised with cloning and sequencing. Several clone libraries were constructed and altogether nearly 6000 clones were sequenced. The microbial communities detected in this study were found to differ from the compost microbes observed in previous research with cultivation based methods or with molecular methods from processes of smaller scale, although there were similarities as well. The bacterial diversity was high. Based on the non-parametric coverage estimations, the number of bacterial operational taxonomic units (OTU) in certain stages of composting was over 500. Sequences similar to Lactobacillus and Acetobacteria were frequently detected in the early stages of drum composting. In tunnel stages of composting the bacterial community comprised of Bacillus, Thermoactinomyces, Actinobacteria and Lactobacillus. The fungal diversity was found to be high and phylotypes similar to yeasts were abundantly found in the full-scale drum and tunnel processes. In addition to phylotypes similar to Candida, Pichia and Geotrichum moulds from genus Thermomyces and Penicillium were observed in tunnel stages of composting. Zygomycetes were detected in the pilot-scale composting processes and in the compost piles. In some of the samples there were a few abundant phylotypes present in the clone libraries that masked the rare ones. The rare phylotypes were of interest and a method for collecting them from clone libraries for sequencing was developed. With negative selection of the abundant phylotyps the rare ones were picked from the clone libraries. Thus 41% of the clones in the studied clone libraries were sequenced. Since microbes play a central role in composting and in many other biotechnological processes, rapid methods for characterization of microbial diversity would be of value, both scientifically and commercially. Current methods, however, lack sensitivity and specificity and are therefore under development. Microarrays have been used in microbial ecology for a decade to study the presence or absence of certain microbes of interest in a multiplex manner. The sequence database collected in this thesis was used as basis for probe design and microarray development. The enzyme assisted detection method, ligation-detection-reaction (LDR) based microarray, was adapted for species-level detection of microbes characteristic of each stage of the composting process. With the use of a specially designed control probe it was established that a species specific probe can detect target DNA representing as little as 0.04% of total DNA in a sample. The developed microarray can be used to monitor composting processes or the hygienisation of the compost end product. A large compost microbe sequence dataset was collected and analysed in this thesis. The results provide valuable information on microbial community composition during industrial scale composting processes. The microarray method was developed based on the sequence database collected in this study. The method can be utilised in following the fate of interesting microbes during composting process in an extremely sensitive and specific manner. The platform for the microarray is universal and the method can easily be adapted for studying microbes from environments other than compost.

Tablettien soveltuvuus annosjakeluun

Koneellinen annosjakelu on kasvava lääkehuollon osa-alue, jossa lääkkeet pakataan koneellisesti pieniin annoskertakohtaisiin pusseihin kahden viikon erissä. Aikaisemmin lääkevalmisteiden soveltuvuutta koneelliseen annosjakeluun ei ole systemaattisesti tutkittu. Tutkimus tehtiin yhteistyössä Espoonlahden apteekin annosjakeluyksikön kanssa ja sen tavoitteena oli määrittää annosjakeluprosessin kannalta optimaaliset ominaisuudet annosjaeltavalle tabletille rikkoutumisten ja siirtymien vähentämiseksi. Rikkoutuminen on lääkevalmisteen murentumista, puolittumista tai muuta rikkoutumista annosjakelun aikana. Siirtymä on lääkevalmisteen jakelu väärään annospussiin. Prosentuaalisesti rikkoutumisia ja siirtymiä on jakelumäärästä hyvin vähän, mutta määrällisesti paljon ja koko ajan enemmän koneellisen annosjakelun yleistyessä. Rikkoutumiset ja siirtymät aiheuttavat paljon lisätyötä pussien korjaamisen takia, joten niiden määrää on pyrittävä vähentämään. Lisäksi tavoitteena oli selvittää lääkkeiden valmistajilta kysyttävissä olevat asiat lääkevalmisteiden ominaisuuksista ja säilyvyydestä, jotta voitaisiin päätellä valmisteen soveltuvuus koneelliseen annosjakeluun kirjallisen tiedon perusteella. Tutkimuksen tulosten perusteella rikkoutumisten ja siirtymien vähentämiseksi optimaalinen tablettivalmiste annosjakeluun on pienehkö tai keskisuuri, päällystetty, luja ja jakouurteeton ja optimaalinen ilman suhteellinen kosteustaso annosjakeluyksikön tuotantotiloissa olisi noin 30 – 40 %. Lääkkeiden valmistajilta kysyttäviä seikkoja ovat koon, päällysteen, murtolujuuden ja jakouurteen lisäksi valmisteen säilyvyys alkuperäispakkauksen ulkopuolella sekä valmisteen valo-, lämpö- ja kosteusherkkyys. Rikkoutumisten ja siirtymien lisäksi tutkittiin myös kosteusherkän asetyylisalisyylihappovalmisteen (Disperin 100 mg) säilyvyyttä 25 °C ja 60 % RH olosuhteissa, koska tuotantotilojen ilman kosteustasoa ei ole säädelty. Säilyvyystutkimuksen kesto oli neljä viikkoa. Se on riittävä, koska se on enimmäisaika, jonka tabletit ovat annosjakeluprosessin yhteydessä pois alkuperäispakkauksestaan ennen käyttöä. Tabletteja säilytettiin avoimessa alkuperäispakkauksessa (purkki), suljetussa alkuperäispakkauksessa, annosjakelukoneen kasetissa ja kahdessa erilaisessa annospussissa (uusi ja käytössä oleva materiaali). Tulosten mukaan annosjakelukoneen kasetti suojaa kosteudelta yhtä huonosti kuin avoin purkki. Uusi pussimateriaali sen sijaan suojaa kosteudelta paremmin kuin tällä hetkellä käytössä oleva materiaali. Raman -spektroskopiamittausten perusteella asetyylisalisyylihappotableteissa ei ehdi neljän viikon seurannan aikana tapahtua asetyylisalisyylihapon hajoamista salisyylihapoksi. Kosteus heikentää tablettien murtolujuutta, mikä saattaa aiheuttaa enemmän rikkoutumisia. Kosteustaso olisi hyvä olla säädettävissä vakioksi tuotantotiloissa tai purkaa tabletit kasetteihin mahdollisimman lähellä jakelua rikkoutumisten ehkäisemiseksi, etenkin ilman kosteustason ollessa korkea. Lisäksi tutkittiin lääkevalmisteen lämpöherkkyyttä koska annosjakelukoneen saumauslaite altistaa annospussit noin 75 °C lämmölle, jos annosjakelukone pysäytetään kesken työn. Tutkimus tehtiin XRPD:llä, jolla voidaan säätää näytteen lämpötilaa. Lämpöherkkyystutkimusten perusteella 75 °C lämpö ei ehdi tunnin aikana aiheuttaa muutoksia karbamatsepiinitabletissa (Neurotol 200 mg). Tuloksista selvisi, että tutkitun valmisteen sisältämä karbamatsepiini ei kuitenkaan ole lämpöherkin muoto, joten muita lämpöherkkiä lääkevalmisteita tulisi tutkia lisätiedon saamiseksi lämmön vaikutuksista.

Notions of Nation : A Critical Discursive Psychology perspective on the Isle of Man

At the the heart of this study can be seen the dual concern of how the nation is represented as a categorical entity and how this is put to use in everyday social interactions.This can be seen as a reaction to the general approach to categorisation and identity functions that tend to be reified and essentialized within the social sciences. The empirical focus of this study is the Isle of Man, a crown dependency situated geographically central within the British Isles while remaining political outside the United Kingdom. The choice of this site was chosen explicitly as ‘notions of nation’ expressed on the island can be seen as being contested and ephemerally unstable. To get at these ‘notions of nation’ is was necessary to choose specific theoretical tools that were able to capture the wider cultural and representational domain while being capable of addressing the nuanced and functional aspects of interaction. As such, the main theoretical perspective used within this study was that of critical discursive psychology which incorporates the specific theoretical tools interpretative repertoires, ideological dilemmas and subject positions. To supplement these tools, a discursive approach to place was taken in tandem to address the form and function of place attached to nationhood. Two methods of data collection were utilized, that of computer mediated communication and acquaintance interviews. From the data a number of interpretative repertoires were proposed, namely being, essential rights, economic worth, heritage claims, conflict orientation, people-as-nation and place-as-nation. Attached to such interpretative repertoires were the ideological dilemmas region vs. country, people vs. place and individualism vs. collectivism. The subject positions found are much more difficult to condense, but the most significant ones were gender, age and parentage. The final focus of the study, that of place, was shown to be more than just an unreflected on ‘container’ of people but was significant in terms of the rhetorical construction of such places for how people saw themselves and the discursive function of the particular interaction. As such, certain forms of place construction included size, community, temporal, economic, safety, political and recognition. A number of conclusions were drawn from the above which included, that when looking at nation categories we should take into account the specific meanings that people attach to such concepts and to be aware of the particular uses they are put to in interaction. Also, that it is impossible to separate concepts neatly, but it is necessary to be aware of the intersection where concepts cross, and clash, when looking at nationhood.
