Sukupuoli ja organisaatiot liikkeessä? Gender and Organisations in Flux?

Viimeaikainen sukupuolta ja organisaatiota käsittelevä tutkimus ja kirjallisuus on saanut paljon (toisinaan epäsuoria) vaikutteita feminismiä ympäröivistä keskusteluista. Lisäksi naisten aseman ja kokemuksien tunnistaminen organisaatioissa ja johtamisessa on vaikuttanut tutkimukseen. Erilaisten kansainvälisesti tutkittujen aiheiden kirjo on laaja: sukupuolisuhteet organisaatioiden ja johtoryhmien kulttuureissa ja kommunikaatiossa; sukupuolittunut työnjako; sukupuolittuneet hierarkiat, valta, auktoriteetti ja johtajuus organisaatioissa ja johtamisessa; sukupuolittuneet markkinat; sukupuolittuneet kuvat, symbolit ja mainokset; sukupuoli ja IT teknologia; seksuaalisuus, häirintä, kiusaaminen ja väkivalta organisaatioissa; työn ja kodin yhteensovittaminen; ja niin edelleen. Myös akateemiset organisaatiot sekä niiden sukupuolittuneet valtasuhteet ja johtaminen kaipaavat kipeästi huomiota. Useimpia mainituista alueista on tutkittu ainakin jonkin verran mutta paljon työtä on vielä myös jäljellä. Tämä kokoelma esittelee ajankohtaista suomalaista tutkimusta seuraavista teemoista: tasa-arvo organisaatioissa, naisjohtajuus, yrittäjyyden sukupuoli, verkostot, sukupuolen representaatio sekä sukupuoli ja uusi teknologia. Kokoelma on työryhmän yhdessä koostama joten se on ennen kaikkea yhteistyön tulos. Recent research and literature on the gendering of organisations has been strongly influenced, though sometimes indirectly, by debates in and around feminism, and on recognising women and women’s situations, experiences and voices in organisations and management. The range of topics and issues that have been studied internationally is vast: gender relations in organizational and management groups, cultures and communication; gender divisions of labour; gender divisions of hierarchy, power, authority and leadership in organizations and management; gendered markets; gender imagery, symbols and advertising; gender and information technology; sexuality, harassment, bullying and violence in organisations; home-work relations; and so on. There are also key issues of gender power relations in academic organizations and management themselves, which need urgent attention. Though most of these areas have been researched to some extent, much remains to be done. This collection brings together current Finnish research on: Equality in Organisations, Women in Management, Gender and Entrepreneurship, Networks, Representation of Gender, Gender and ICTs. The book has been put together by an editorial team and is thus first and foremost a collective effort.

Late Svecofennian leucogranites of southern Finland : Chronicles of an orogenic collapse

Leucogranite magmatism occurred in southern Finland during the later stages of the Paleoproterozoic Svecofennian orogeny. The leucogranites are considered to have formed from pre-existing crustal rocks that have undergone anatexis in the extensional stage of the orogeny, following continental collision and resultant crustal thickening. The leucogranites have been studied in the field using petrographic and mineralogical methods, elemental and isotope geochemistry on whole rocks and minerals, and U-Pb geochronology. On outcrop scale, these granites typically form heterogeneous, layered, sheet-like bodies that migmatize their country rocks. All of the leucogranites are peraluminous and rich in SiO2, but otherwise display significant geochemical variation. Their Nd isotope composition ranges from fairly juvenile to very unradiogenic, and the Hf isotope composition of their zircon shows a varying degree of mixing in the source, the zircon populations becoming more heterogeneous and generally less radiogenic towards the east. The leucogranites have been dated using U-Pb isotopic analyses, utilizing thermal ionization mass spectrometry, secondary ion mass spectrometry, and laser ablation multicollector ICP mass spectrometry on zircon and monazite. The results show that the granites were emplaced between 1.85 Ga and 1.79 Ga, which is a considerably longer period than has traditionally been perceived for these rocks. The rocks tend to become younger towards the east. Single crystal data also display a wide array of inherited zircons, especially in the eastern part of the leucogranite belt. The most common inherited age groups are ~2.8 2.5 Ga, ~2.1 2.1 Ga, and ~1.9 Ga. Magmatic zircon and monazite usually record similar ages for any one sample.Thermobarometric calculations indicate that the leucogranites in the Veikkola area of southcentral Finland were formed from relatively low-temperature melts, and emplaced at 17-25 km depth, i.e. at mid-crustal level. It is likely that these conditions apply to the Svecofennian leucogranites in general. Large differences in the Hf and Nd isotope compositions, emplacement ages, and distributions of inherited zircon ages show that these granites were formed from different types of source rocks, which probably included both sedimentary and igneous rocks.

Vastasyntyneen varsan sepsis osa II - Infektion diagnosoiminen, aiheuttajamikrobit ja mikrobilääkeresistenssi

Sepsis eli infektion aiheuttama yleistynyt tulehdusreaktio on merkittävä kuolleisuuden aiheuttaja vastasyntyneillä varsoilla. Kirjallisuuskatsauksessa on käsitelty sepsiksen patofysiologiaa ja kliinisiä oireita vastasyntyneillä varsoilla sekä sepsikselle altistavia tekijöitä. Vastasyntyneen varsan sepsiksen diagnosoimisessa kliinisten oireiden arvioinnilla on keskeinen merkitys sairauden varhaisessa tunnistamisessa ja hoidon aloittamisessa. Sairauden nopean etenemisen ja veriviljelytulosten hitaan valmistumisen vuoksi antibioottihoito joudutaan aloittamaan jo ennen viljelytulosten valmistumista. Veriviljelyllä on kuitenkin tärkeä merkitys sepsisdiagnoosin ja valitun antibioottihoidon varmistamisessa. Sairaalakohtaisten veriviljelynäytetulosten seuranta mahdollistaa ensisijaisen mikrobilääkkeen valinnan aiemmin eristettyjen aiheuttajamikrobien esiintyvyyden ja mikrobilääkeherkkyyksien perusteella. Yleisimpiä vastasyntyneen varsan sepsiksen aiheuttajia ovat kirjallisuuden mukaan suolistoperäiset gram-negatiiviset bakteerit. Escherichia colin osuus vastasyntyneiltä varsoilta otetuista veriviljelynäytteistä eristetyistä bakteerikannoista on vaihdellut eri tutkimuksissa 18,7 - 50,0 %. Pohjois-Amerikassa tehdyissä tutkimuksissa varsojen veriviljelynäytteistä eristettyjen E.coli -kantojen herkkyys yleisesti käytetylle trimetopriimi-sulfadiatsiinille on ollut huono (57–71 %). Penisilliinin ja gentamisiinin yhdistelmälle enterobakteerien herkkyyden on raportoitu olevan hyvä. Suomessa tilanteen on arvioitu olevan parempi. Tutkimuksessa kartoitettiin retrospektiivisesti veriviljelyn käyttöä varsojen sepsiksen diagnostiikassa, sepsiksen aiheuttajamikrobien esiintymistä ja mikrobilääkkeiden käyttöä Yliopistollisessa eläinsairaalassa (YES) vuosina 2004–2006. Tutkimusaineisto koostuu yhteensä 90 korkeintaan 10 päivän ikäisenä YES:aan tuodun varsan potilastiedoista. Sairaalaan saapuneista varsoista 30 % oli otettu veriviljelynäyte. Veriviljelynäytteistä positiivisia oli 62,5 %. 60 % positiivisista näytteistä kasvoi vähintään kahta bakteerilajia. Yleisin aiheuttajabakteeri oli Escherichia coli (23,1 %). Yksi eristetyistä E.coli -kannoista oli resistentti ampisilliinille, gentamisiinille ja trimetopriimi-sulfadiatsiinille. Aineiston pienen koon vuoksi tutkimus ei kuitenkaan anna luotettavaa kuvaa eristettyjen aiheuttajamikrobien mikrobilääkeherkkyydestä laajemmin. Sekakasvujen osuus oli suuri ja tyypillisten veriviljelynäytteitä kontaminoivien bakteerilajien (Streptococcus viridans sp., Micrococcus sp., koagulaasinegatiiviset stafylokokit) osuus oli yli 30 % eristetyistä bakteerikannoista. Tämä viittaa ongelmiin veriviljelynäytteenottotekniikassa riittävän aseptiikan saavuttamien osalta. Koagulaasinegatiiviset stafylokokit voivat myös aiheuttaa sepsiksen, mutta niiden merkitys vastasyntyneiden varsojen sepsiksen aiheuttajina on epäselvä.

Kädestä suuhun : Makro- ja mikrotaloudellinen tarkastelu suomalaisten kotitalouksien säästämisestä ja sen mittaamisesta 1950-luvulla

This study is divided into two parts: a methodological part and a part which focuses on the saving of households. In the 1950 s both the concepts as well as the household surveys themselves went through a rapid change. The development of national accounts was motivated by the Keynesian theory and the 1940 s and 1950 s were an important time for the development of the national accounts. Before this, saving was understood as cash money or money deposited in bank accounts but the changes in this era led to the establishment of the modern saving concept. Separate from the development of national accounts, household surveys were established. Household surveys have been conducted in Finland from the beginning of the 20th century. At that time surveys were conducted in order to observe the working class living standard and as a result, these were based on the tradition of welfare studies. Also a motivation for undertaking the studies was to estimate weights for the consumer price index. A final reason underpinning the government s interest in observing this data regarded whether there were any reasons for the working class to become radicalised and therefore adopt revolutionary ideas. As the need for the economic analysis increased and the data requirements underlying the political decision making process also expanded, the two traditions and thus, the two data sources started to integrate. In the 1950s the household surveys were compiled distinctly from the national accounts and they were virtually unaffected by economic theory. The 1966 survey was the first study that was clearly motivated by national accounts and saving analysis. This study also covered the whole population rather than it being limited to just part of it. It is essential to note that the integration of these two traditions is still continuing. This recently took a big step forward as the Stiglitz, Sen and Fitoussi Committee Report was introduced and thus, the criticism of the current measure of welfare was taken seriously. The Stiglitz report emphasises that the focus in the measurement of welfare should be on the households and the macro as well as micro perspective should be included in the analysis. In this study the national accounts are applied to the household survey data from the years 1950-51, 1955-56 and 1959-60. The first two studies cover the working population of towns and market towns and the last survey covers the population of rural areas. The analysis is performed at three levels: macro economic level, meso level, i.e. at the level of different types of households, and micro level, i.e. at the level of individual households. As a result it analyses how the different households saved and consumed and how that changed during the 1950 s.

Polymeereillä stabiloitu amorfinen formulaatio

Nowadays growing number of new active pharmaceutical ingredients (API) have large molecular weight and are hydrophobic. The energy of their crystal lattice is bigger and polarity has decreased. This leads to weakened solubility and dissolution rate of the drug. These properties can be enhanced for example by amorphization. Amorphous form has the best dissolution rate in the solid state. In the amorphous form drug molecules are randomly arranged, so the energy required to dissolve molecules is lower compared to the crystalline counterpart. The disadvantage of amorphous form is that it is unstable. Amorphous form tends to crystallize. Stability of amorphous form can be enhanced by adding an adjuvant to drug product. Adjuvant is usually a polymer. Polymers prevent crystallization both by forming bonds with API molecules and by steric hindrance. The key thing in stabilizing amorphous form is good miscibility between API and polymer. They have to be mixed in a molecular level so that the polymer is able to prevent crystallization. The aim of this work was to study miscibility of drug and polymer and stability of their dispersion with different analytical methods. Amorphous dispersions were made by rotary evaporator and freeze dryer. Amorphicity was confirmed with X-ray powder diffraction (XRPD) right after preparation. Itraconazole and theophylline were the chosen molecules to be stabilized. Itraconazole was expected to be easier and theophylline more difficult to stabilize. Itraconazole was stabilized with HPMC and theophylline was stabilized with PVP. Miscibility was studied with XRPD and differential scanning calorimetry (DSC). In addition it was studied with polarized light microscope if miscibility was possible to see visually. Dispersions were kept in stressed conditions and the crystallization was analyzed with XRPD. Stability was also examined with isothermal microcalorimetry (IMC). The dispersion of itraconazole and theophylline 40/60 (w/w) was completely miscible. It was proved by linear combination of XRPD results and single glass transition temperature in DSC. Homogenic well mixed film was observed with light microscope. Phase separation was observed with other compositions. Dispersions of theophylline and PVP mixed only partly. Stability of itraconazole dispersions were better than theophylline dispersions which were mixed poorer. So miscibility was important thing considering stability. The results from isothermal microcalorimetry were similar to results from conventional stability studies. Complementary analytical methods should be used when studying miscibility so that the results are more reliable. Light microscope is one method in addition to mostly used XRPD and DSC. Analyzing light microscope photos is quite subjective but it gives an idea of miscibility. Isothermal microcalorimetry can be one option for conventional stability studies. If right conditions can be made where the crystallization is not too fast, it may be possible to predict stability with isothermal microcalorimetry.

The Church and Its Boundaries : A Study of the Special Commission on Orthodox Participation in the WCC

The relationship between the Orthodox Churches and the World Council of Churches (WCC) became a crisis just before the 8th Assembly of the WCC in Harare, Zimbabwe in 1998. The Special Commission on Orthodox Participation in the WCC (SC), inaugurated in Harare, worked during the period 1999 2002 to solve the crisis and to secure the Orthodox participation in the WCC. The purpose of this study is: 1) to clarify the theological motives for the inauguration of the SC and the theological argumentation of the Orthodox criticism; 2) to write a reliable history and analysis of the SC; 3) to outline the theological argumentation, which structures the debate, and 4) to investigate the ecclesiological questions that arise from the SC material. The study spans the years 1998 to 2006, from the WCC Harare Assembly to the Porto Alegre Assembly. Hence, the initiation and immediate reception of the Special Commission are included in the study. The sources of this study are all the material produced by and for the SC. The method employed is systematic analysis. The focus of the study is on theological argumentation; the historical context and political motives that played a part in the Orthodox-WCC relations are not discussed in detail. The study shows how the initial, specific and individual Orthodox concerns developed into a profound ecclesiological discussion and also led to concrete changes in WCC practices, the best known of which is the change to decision-making by consensus. The Final Report of the SC contains five main themes, namely, ecclesiology, decision-making, worship/common prayer, membership and representation, and social and ethical issues. The main achievement of the SC was that it secured the Orthodox membership in the WCC. The ecclesiological conclusions made in the Final Report are twofold. On the one hand, it confirms that the very act of belonging to the WCC means the commitment to discuss the relationship between a church and churches. The SC recommended that baptism should be added as a criterion for membership in the WCC, and the member churches should continue to work towards the mutual recognition of each other s baptism. These elements strengthen the ecclesiological character of the WCC. On the other hand, when the Final Report discusses common prayer, the ecclesiological conclusions are much more cautious, and the ecclesiological neutrality of the WCC is emphasized several times. The SC repeatedly emphasized that the WCC is a fellowship of churches. The concept of koinonia, which has otherwise been important in recent ecclesiological questions, was not much applied by the SC. The comparison of the results of the SC to parallel ecclesiological documents of the WCC (Nature and Mission of the Church, Called to Be the One Church) shows that they all acknowledge the different ecclesiological starting points of the member churches, and, following that, a variety of legitimate views on the relation of the Church to the churches. Despite the change from preserving the koinonia to promises of eschatological koinonia, all the documents affirm that the goal of the ecumenical movement is still full, visible unity.

Change detection and controlling forest information using multi-temporal Landsat TM imagery.

A method was developed for relative radiometric calibration of single multitemporal Landsat TM image, several multitemporal images covering each others, and several multitemporal images covering different geographic locations. The radiometricly calibrated difference images were used for detecting rapid changes on forest stands. The nonparametric Kernel method was applied for change detection. The accuracy of the change detection was estimated by inspecting the image analysis results in field. The change classification was applied for controlling the quality of the continuously updated forest stand information. The aim was to ensure that all the manmade changes and any forest damages were correctly updated including the attribute and stand delineation information. The image analysis results were compared with the registered treatments and the stand information base. The stands with discrepancies between these two information sources were recommended to be field inspected.

Chemical Characterization of Urban Background Aerosol Using Online And Filter Methods

In order to evaluate the influence of ambient aerosol particles on cloud formation, climate and human health, detailed information about the concentration and composition of ambient aerosol particles is needed. The dura-tion of aerosol formation, growth and removal processes in the atmosphere range from minutes to hours, which highlights the need for high-time-resolution data in order to understand the underlying processes. This thesis focuses on characterization of ambient levels, size distributions and sources of water-soluble organic carbon (WSOC) in ambient aerosols. The results show that in the location of this study typically 50-60 % of organic carbon in fine particles is water-soluble. The amount of WSOC was observed to increase as aerosols age, likely due to further oxidation of organic compounds. In the boreal region the main sources of WSOC were biomass burning during the winter and secondary aerosol formation during the summer. WSOC was mainly attributed to a fine particle mode between 0.1 - 1 μm, although different size distributions were measured for different sources. The WSOC concentrations and size distributions had a clear seasonal variation. Another main focus of this thesis was to test and further develop the high-time-resolution methods for chemical characterization of ambient aerosol particles. The concentrations of the main chemical components (ions, OC, EC) of ambient aerosol particles were measured online during a year-long intensive measurement campaign conducted on the SMEAR III station in Southern Finland. The results were compared to the results of traditional filter collections in order to study sampling artifacts and limitations related to each method. To achieve better a time resolution for the WSOC and ion measurements, a particle-into-liquid sampler (PILS) was coupled with a total organic carbon analyzer (TOC) and two ion chromatographs (IC). The PILS-TOC-IC provided important data about diurnal variations and short-time plumes, which cannot be resolved from the filter samples. In summary, the measurements made for this thesis provide new information on the concentrations, size distribu-tions and sources of WSOC in ambient aerosol particles in the boreal region. The analytical and collection me-thods needed for the online characterization of aerosol chemical composition were further developed in order to provide more reliable high-time-resolution measurements.

Determination of intestinal permeability in healthy horses using the contrast medium iohexol

Tämä lisensiaatin tutkielma koostuu kolmesta osasta; kirjallisuuskatsauksesta, kokeellisesta osasta ja liitteistä. Iohexol on ionisoitumaton, trijodattu ja vesiliukoinen röntgenvarjoaine. Iohexolia on hyödynnetty lääketieteessä useita vuosia. Iohexolia on käytetty muun muassa angio- ja myelografiassa, lisäksi iohexolia on hyödynnetty arvioitaessa munuaiskerästen suodattumisnopeutta sekä suoliston läpäisevyyden muutoksia. Hevosen tulehduksellisessa suolistosairaudessa (Inflammatory bowel disease, IBD) suoliston rakenne ja sen läpäisevyys muuttuu; tyypillistä on tulehdussolujen kertyminen suoliston seinämään ja myös sidekudosmuodostusta saattaa esiintyä. Suolisto muutoksia saatetaan havaita sekä ohut- että paksusuolessa. IBD aiheuttaa hevoselle laihtumista, johtuen ravintoaineiden puutteellisesta imeytymisestä ja proteiinien menetyksestä suoleen suoliston häiriötilan yhteydessä. Tällä hetkellä IBD:n diagnostiikka perustuu tyypillisiin oireisiin, kliiniseen tutkimukseen, verinäytteisiin, glukoosin imeytymistestiin ja peräsuolesta otettuun koepalaan. IBD:n diagnostiikka on kuitenkin erittäin haastavaa ja tutkimusmenetelmiin liittyy lukuisia ongelmia, jotka vähentävät niiden luotettavuutta IBD:n diagnostiikassa. Tutkimuksemme tarkoituksena on kehittää hevosen IBD:n diagnostiikkaa entistä helpompaan, luotettavampaan ja turvallisempaan suuntaan. Tämän alustavan tutkimuksen tavoitteet olivat: (1) tutkia voidaanko iohexol havaita hevosen seerumissa oraalisen annostelun jälkeen ja (2) muodostaa iohexolin pitoisuuskuvaaja ajan funktiona terveillä hevosilla. Materiaalimme koostui kymmenestä terveestä hevosesta, joilla ei ollut havaittu laihtumista tai ripulia. Ennen iohexolin annostelua hevosille suoritettiin kliininen tutkimus ja verinäytteet otettiin maha-suolikanavan sairauden poissulkemiseksi. Hevosille suoritettiin myös mahalaukun tähystys. 16 tunnin paaston jälkeen 1 ml/kg Iohexolia annosteltiin 10 % -liuoksena nenämahaletkulla suoraan mahaan ja verinäytteet otettiin 0, 30, 60, 120, 180, 240, 300 ja 360 minuuttia annostelun jälkeen. Iohexolin pitoisuus määritettiin käyttämällä korkean erotuskyvyn nestekromatografiaa. Iohexolin pitoisuuksista tietyillä ajanhetkillä muodostettiin kuvaaja. Hevosilla ei havaittu maha-suolikanavan sairauksia. Kaikki hevoset olivat hyvässä kuntoluokassa ja mahalaukun tähystyksessä ei havaittu merkittäviä muutoksia. Verinäytteiden tulokset olivat viiterajoissa. Kaikki hevoset sietivät iohexolia hyvin ja haittavaikutuksia ei havaittu. Iohexol oli havaittavissa seerumissa 60 minuutin kuluttua annostelusta. Kuvaajassa voitiin havaita kaksi huippua. Statistiset menetelmät tukivat löydöksiä. Iohexol testi oli yksinkertainen suorittaa ja siihen ei liittynyt haittavaikutuksia. Annos 1ml/kg oli havaittavissa seerumissa. Iohexolin pitoisuuskuvaaja muodosti kaksi huippua, ja tämänkaltainen ilmiö on kuvattu kirjallisuudessa aikaisemmin useiden lääkkeiden tapauksessa. Hevosella ilmiö liittyy todennäköisesti maha-suolikanavan rakenteellisiin ja fysiologisiin eroavaisuuksiin ja lisätutkimuksia ilmiön varmistamiseksi tarvitaan. Iohexol näyttää olevan potentiaalinen merkkiaine suoliston läpäisevyyden arviointiin ja lisätutkimuksia IBD:tä sairastavien hevosten seerumin iohexolin pitoisuuksista verrattuna terveiden hevosten seerumin iohexolin pitoisuuksiin on suunnitteilla.
