Muuttuva ja pysyvä suurvalta. Yhdysvallat suomalaisten sanomalehtien kommentoivissa teksteissä erilaisina maailmanpoliittisina kausina

Tutkielman tarkoituksena on tarkastella sitä muutosta, jonka Yhdysvallat käy läpi suomalaisten sanomalehtien kommentoivissa teksteissä lähihistorian aikana. Tarkemmin ilmaistuna, tarkoituksena on ollut selvittää, näyttäytyykö Yhdysvallat suomalaisissa sanomalehtikommenteissa pelkästään maailmanpoliittisten muutosten ja presidenttien vaihdosten valossa vai onko mukana jonkin pidempi, historiallinen tematiikka, jolla Yhdysvalloista normaalisti kirjoitetaan ja jolla presidentin linjapuhetta kommentoidaan. Tutkimuksen näkökulmana ja samalla metodologisena viitekehyksenä on diskurssianalyysin ja sosiaalisen konstruktionismin näkökulma. Tarkoituksena on tarkastella kommentoivia tekstejä, ei pelkästään sosiaalisen todellisuuden tapahtumia raportoivina tai heijastavina, vaan myös sosiaalista todellisuutta rakentavina. Koska diskurssianalyysi ei itsessään ole selkeä tai yhtenäinen analyysimenetelmä, työssä on käytetty menetelmällisenä työkaluna kriittisen lingvistiikan analyysitapaa. Tutkimusaineistoa on analysoitu erityisesti Vesa Heikkisen (1999) ja Sari Pietikäisen (2000) analyysitapoja hyödyntäen. Tärkeimpinä teoreettisina taustaoletuksina edellisten tavoin myös tässä tutkielmassa ovat diskurssianalyysin eri suuntauksia edustavat lähteet kuten Faircloughn (1992, 1997, 2003) sekä van Dijkin (1985, 1999) ja Gunther Kressin (1985) näkemykset tästä lähestymistavasta. Koska tutkittava ilmiö kiinnittyy niin sanomalehtien pääkirjoitusten kuin poliittisen historiankin konteksteihin, on ilmiön taustoittamiseksi ja johtopäätösten tueksi nojattu myös esimerkiksi Salovaara-Moringin (2004, 2009), Rusin (2003), Jakobsonin (1998, 2005) ja Hemánuksen (1972, 1983) ajatuksiin. Tutkielman aineisto on rajattu viimeisten 25 vuoden ajalle siten, että on poimittu neljä maailmanpoliittisten muutosten tai Yhdysvaltain presidentin vaihdosten kannalta olennaista aikakautta. Samalla on noudatettu suurimmalta osalta myös sen kansainvälisen tutkimusprojektin rajauksia, jonka osana tämä tutkielma syntyi. Tutkimusaineistoa on siten kerätty vuosilta 1984, 1994, 2004 sekä 2010. Mukaan on kyseisiltä vuosilta otettu Yhdysvaltain presidentin pitämän linjapuheen pitopäivästä kaksi viikkoa eteenpäin kestävä periodi, jonka ajalta on kerätty neljän suomalaisen sanomalehden kommentoivat tekstit, pääkirjoitukset, kolumnit ja tausta-artikkelit, joissa otetaan kantaa Yhdysvaltain presidentin pitämään vuosittaiseen linjapuheeseen. Tutkimusaineiston valossa Yhdysvallat näyttäytyy suomalaisten sanomalehtikommentaattoreiden teksteissä toisaalta muuttuvana, mutta samalla myös muuttumattomana suurvaltana. Maailmanpoliittinen muutos – siirtymä kylmästä sodasta yhden suurvallan aikaan näkyy suomalaisessa kommentoinnissa. Samoin näyttäytyy selkeänä kahden erilaisen presidentin, George W. Bushin ja Barack Obaman vastaanotto. Toisaalta aineistossa ei näy pelkästään muutos, vaan Yhdysvallat on suomalaisille kommentoijille myös muuttumaton suurvalta jolta odotetaan paljon ja jota kritisoidaan sen mukaan – aikakaudesta riippuen joko suomalaisesta tai eurooppalaisesta positiosta käsin.

Sex steroids in Sjögren's syndrome

Sjögren s syndrome (SS) is a strongly female dominant autoimmune disease. SS targets mainly salivary and lacrimal glands and leads to loss of the secreting acinar cells of these glands. Accordingly, secretion of the affected glands is diminished and the main symptoms of SS, dryness of mouth and eyes, follow. In addition to these sicca symptoms, SS patients suffer from severe fatigue and can have various extraglandular symptoms. To date, the etiology of SS still remains unknown. Female dominance and the late onset of the disease simultaneously with remarkable hormonal changes in the body (menopause, adrenopause) encouraged us to hypothesize that sex steroids, especially androgens, are involved in the onset and progression of SS. We confirmed our hypothesis and showed that patients with SS suffer from androgen depletion both systemically and locally in the target tissue of SS, salivary glands. We especially focused on the local androgen environment in salivary glands and demonstrated that healthy salivary glands contain a complete enzymatic machinery for local synthesis of androgens and estrogens from pro-hormone dehydroepiandrosterone (DHEA). However, in SS salivary glands the enzymes catalyzing the local androgen synthesis are defective and, in a subgroup of patients, practically non-functional. Probably due to this local defect in DHEA processing, therapy with DHEA was found unbeneficial for SS patients in the treatment of fatigue. We also studied the effect of the local androgen depletion on salivary glands. We found that in salivary gland cells and healthy labial salivary glands androgens upregulate integrin subunits α1 and α2, which are important for the communication, differentiation and function of the acinar cells. On the contrary, in SS salivary glands DHEA failed to upregulate these signaling molecules, again probably due to defective processing of DHEA into active androgens. Our finding highlights the importance of the local androgen environment and local DHEA processing for the function and welfare of salivary glands. In conclusion, this study showed that patients with SS are androgen depleted both systemically and locally in salivary glands. SS patients also have a defective local sex steroid synthesizing enzymatic machinery further impairing the local androgen depletion. We also showed that the local androgen defect leads to decreased expression of acinar cell specific integrin molecules, which impairs the signaling between the acinar cells and basement membrane and might thus explain the acinar cell loss seen in SS salivary glands. By showing the importance of the local sex steroid imbalance in SS we have clarified some etiopathogenetic mechanisms of SS, which have thus far remained unknown.

Depression and Cognition in Type 2 Diabetes from a Life Course Perspective

Background: Type 2 diabetes is linked to several complications which add to both physical and mental distress. Depression is a common co-morbidity of diabetes which can occur both as a cause and a consequence of type 2 diabetes. Depression has been shown to correlate with glucose regulation and treating depression might prove beneficial for glucose regulation as well as for mental well being. Another complication which might affect diabetes management is cognitive decline. Several risk factors and complications of diabetes might modify the risk for developing cognitive impairment, which is increased 1.5 times among subjects with type 2 diabetes. Type 2 diabetes, depression and impaired cognitive performance have all been linked to low birth weight. This thesis aimed to explore the effects and interactions of birth weight, depression and cognitive ability in relation to type 2 diabetes from a life course perspective. Subjects and methods: Studies I, II and V were part of the Helsinki Birth Cohort Study. 2003 subjects participated in an extensive clinical examination at an average age of 61 years. A standard glucose tolerance test (OGTT) was performed and depressive symptoms were assessed using the Beck Depression Inventory (BDI). In addition data was obtained from child welfare clinics and national registers. A subset of the cohort (n=1247) also performed a test on cognitive performance (CogState ®) at the average age of 64. Studies III and IV were randomised clinical trials where mildly depressed diabetic subjects were treated with paroxetine or placebo and the effect on metabolic parameters and quality of life was assessed. The first trial included 14 women and lasted 10 weeks, while the second trial included 43 subjects, both men and women, and lasted 6 months. Results: Type 2 diabetes was positively associated with the occurrence of depressive symptoms. Among diabetic subjects 23.6% had depressive symptoms, compared to 16.7% of subjects with normal glucose tolerance (OR = 1.77, p<0.001). Formal mediation analysis revealed that cardiovascular disease (CVD) is likely to act as a mediator in the association. Furthermore, low birth weight was found to modify the association between type 2 diabetes, CVD and depression. The association between BDI score and having type 2 diabetes or CVD was twice as strong in the subgroup with low birth weight (≤ 2500g) compared with the group with birth weight > 2500g (p for interaction 0.058). In the six months long randomised clinical trial (study IV) paroxetine had a transient beneficial effect on glycosylated haemoglobin A1c (GHbA1c) and quality of life when compared to placebo after three months of treatment. In study V we found that subjects with known diabetes had a consistently poorer level of cognitive performance than subjects with normal glucose tolerance in most of the tested cognitive domains. This effect was further amplified among those born with a small birth weight (p for interaction 0.002). Conclusions: Type 2 diabetes is associated with a higher occurrence of depressive symptoms compared to subjects with normal glucose tolerance. This association is especially strong among subjects with CVD and those born with a low birth weight. Treating depressed diabetic subjects with paroxetine has no long term effect on glucose regulation. Physicians should be aware of depression as an important co-morbidity of type 2 diabetes. Both depression and the cognitive decline often seen among diabetic subjects are increased if the subject is born with a low birth weight. Physicians should recognise low birth weight as an additional risk factor and modifier of diabetic complications.

Prosopis, an Alien among the Sacred Trees of South India

The problematic of invasive species in an alien environment has aroused the attention of scientists all over the world for quite some time. One of the exotic tree species that has provoked special attention in the tropical drylands is Prosopis juliflora. Originating in South America, prosopis (hereafter referred to as prosopis) has been introduced in the hot and semi-arid zones of the world particularly to provide fuelwood, to stabilize sand dunes and to combat desertification. The tree has become an essential source for fuelwood and a provider of several other products and services in areas where it has become established. However, despite the numerous benefits the tree provides to rural people, in several regions prosopis has become a noxious weed with a negative impact on the environment and to the economy of farmers and landowners. In India, prosopis was introduced in Andhra Pradesh in 1877. The tree was then proclaimed as the precious child of the plant world by scientists and local people alike. The purpose of this study was to investigate the overall impact of prosopis on local rural livelihoods in the drylands of South India. Of particular interest was the examination of the different usages of the tree, especially as fuelwood, and people s perceptions of it. Furthermore, the study examined the negative impacts of the uncontrolled invasion of prosopis on croplands, and its occupation of the banks of irrigation canals and other water sources. As another central theme, this study analysed the Hindu classification system for nature and for trees in particular. In India, several tree species are regarded as sacred. This study examined the position of the exotic prosopis among sacred trees, such as the bodhi, banyan and neem trees. The principle method for collecting the field data was by using individual and thematic group interviews. These interviews were semi-structured with open ended questions. Moreover, unstructured interviews as well as general observations provided complementary information. The data were gathered during two fieldwork periods in the states of Andhra Pradesh and Tamil Nadu, in South India. The results confirmed that prosopis both provides benefits and causes hazards to different stakeholders. Farmers and agriculturalists suffer economic losses in areas where prosopis has invaded crop fields and competes with other plants for water and nutrients. On the other hand, for a significant number of poor rural people, prosopis has become an important source of livelihood benefits. This tree, which grows on government wastelands, is commonly a free resource for all and has thus become a major local source of fuelwood. It also provides several other goods and services and cash income that contributes to improve livelihoods in rural communities. Prosopis ranked lowest in the tree classificatioin system of the Hindus of South India. Although it is appreciated for many benefits it provides for poor people, it has remained an outsider compared with the indigenous tree species. On the other hand, the most sacred trees, such as the bodhi or the banyan, are completely excluded from extraction and it is seen as a sacrilege to even cut branches from any of these trees. An unexpected finding was that, in a few cases, prosopis had also been elevated to the status of a sacred tree. Goods and services from prosopis are not utilized in the most beneficial way. Silvicultural management practices are suggested that would provide additional income and employment opportunities. Interventions are recommended to control further invasion of the tree that might cause serious negative effects in the future. For Hindus, the sacred always ranks highest, even above economic gain. The conservation of sacred groves and sacred trees is a tradition that has its roots in ancient history. These socio-religious practices need to be respected and continued. Successful management of tree and forest resources depends on the willingness of the local people to manage their natural resources, and this willingness exists and has always existed in South India. Keywords: South India, drylands, livelihood, fuelwood, invasive, resource, silviculture.

The RATAS-project, in the Light of 25 Years of Development Towards Computer-Integrated Construction

In smaller countries where the key players in construction IT development tend to know each other personally and where public R&D funding is concentrated to a few channels, IT roadmaps and strategies would seem to have a better chance of influencing development than in the bigger industrial countries. In this paper Finland and the RATAS-project is presented as a historical case illustrating such impact. RATAS was initiated as a construction IT roadmap project in 1985, involving many of the key organisations and companies active in construction sector development. Several of the individuals who took an active part in the project have played an important role in later developments both in Finland and on the international scene. The central result of RATAS was the identification of what is nowadays called Building Information Modelling (BIM) technology as the central issue in getting IT into efficient use in the construction sector. BIM, which earlier was referred to as building product modelling, has been a key ingredient in many roadmaps since and the subject of international standardisation efforts such as STEP and IAI/IFCs. The RATAS project can in hindsight be seen as a forerunner with an impact which also transcended national borders.

Hyvät pahat pörssiyhtiöt?

Pörssiyhtiöihin liitetään julkisessa keskustelussa usein väitteitä, että pörssiyhtiöt palvelevat osakkeenomistajien lyhytaikaisia etuja muiden sidosryhmien ja myös pitkän aikavälin tuottavuuden kustannuksella. Keskitymme tässä selonteossa tutkimaan onko pörssiyhtiöiden julkisuudessa osalleen saama kritiikki ansaittua. Erityisesti tarkastelemme pörssiyhtiöiden roolia työnantajina ja investoijina 2000- luvulla verrattuna noteeraamattomien yritysten rooliin. Selvitämme myös listattujen ja listaamattomien yritysten eroja sijoituskohteina sekä tutkimme, onko pörssissä ololla vaikutusta yrityksen rahoitusrakenteeseen. Olemme jättäneet vertailun ulkopuolelle nopeasti kasvaneet ja kannattavat tietotekniikka-alan yritykset, joille ei ole olemassa noteeraamattomia vertailukohteita. Lisäksi vertailustamme olemme jättäneet pois yritykset, jotka eivät ole olleet listattuina koko tarkasteluperiodimme aikana. Pois jättämämme kasvuyritykset todennäköisesti parantaisivat pörssiyhtiöiden suhteellista asemaa ainakin kasvu- ja tulosnäkökulmista. Osakkeenomistajien edun lyhytnäköisen valvonnan tulisi johtaa työntekijöiden hyväksikäyttöön ja pitkäaikaisinvestointien karttamiseen. Tuloksemme kuitenkin kertovat päinvastaista. Pörssiyhtiöiden työntekijäkohtaiset henkilökulut ovat selvästi samoilla aloilla toimivia noteeraamattomia yrityksiä korkeammat. Erot ovat huomattavat: pörssiyhtiöiden vuosittaiset henkilökulut ovat noin 3000–4000 euroa suuremmat per henkilö. Lisäksi pörssiyhtiöt ovat kasvattaneet työntekijämääräänsä huomattavasti, toisin kuin noteeraamattomat vertailuyritykset. Otantamme pörssiyhtiöiden kokonaistyöllisyys on 2000-luvulla kasvanut keskimäärin noin 3 % vuodessa. Pörssiyhtiöt työllistivät vuonna 2007 lähes 87.000 työntekijää enemmän kuin vuonna 2001, kun taas yksityisen vertailuryhmän osalta työpaikat olivat samaan aikaan vähentyneet noin 2 500:lla. Pörssiyhtiöiden investoinnit ovat useina vuosina olleet listaamattomia yrityksiä suuremmat, joskin erot kahden ryhmän välillä eivät tyypillisesti ole tilastollisesti merkittäviä. Sidosryhmien hyväksikäytölle tai lyhytjänteisyydelle ei siis tältä osin löydy minkäänlaisia todisteita. Investointituotoissa ei ole järjestelmällisiä eroja kahden ryhmän välillä, lukuunottamatta aivan viime vuosia, jolloin pörssiyhtiöiden oman pääoman tuotto on ollut selvästi korkeampi kuin noteeraamattomien yritysten. Pörssiyhtiöillä ja noteeraamattomilla vertailuyrityksillä on merkittäviä eroja osingonmaksussa. Pörssiyhtiöt maksavat selvästi korkeampia osinkoja kuin vertailuryhmään kuuluvat yritykset. Pörssiyhtiöt maksavat omistajilleen noin puolet nettotuloksistaan osinkoina, kun taas noteeraamattomat yritykset maksavat ainoastaan 20–30 %. Erot pörssiyhtiöiden hyväksi ovat vielä suurempia, kun mittarina käytetään osinkojen suhdetta liikevaihtoon. Tulostemme mukaan pörssiyhtiöt käyttävät velkarahoitusta vastaavia noteeraamattomia yrityksiä enemmän. Tämä voi johtua kahdesta syystä. Ensinnäkin, koska osakkeen julkinen kauppa mahdollistaa omistuspohjan laajenemisen ja alkuperäisyrittäjien sijoitusten paremman hajauttamisen, pörssiyrityksellä on suurempi halukkuus riskinottoon lisäämällä velkarahoitusta. Toisaalta pörssilistaus voi toimia signaalina yrityksen laadusta siten, että rahoittajat tarjoavat velkarahoitusta auliimmin ja paremmilla ehdoilla. Pörssiyhtiöiden suurempi velkaisuus ei ole ollenkaan negatiivinen asia, koska velkarahoitus on verohyötyineen tyypillisesti huomattavasti osakerahoitusta edullisempaa. Tämä taas mahdollistaa lisäinvestointeja, joita ei rahoituksen puutteessa muuten tehtäisi. Yleisemmin rahoitusrakenteiden eroja tarkastellessamme huomaamme viitteitä siitä, että koska pörssiyhtiöillä on mahdollisuus saada osakepääomaa helpommin kuin listaamattomien yhtiöiden, ne pystyvät reagoimaan sekä tuote-, että rahoitusmarkkinoiden 3 mahdollisuuksiin. Listaamattomien yritysten rahoitusrakenne ja myös investoinnit sen sijaan näyttäisivät olevan pitkälle sidonnaisia tulorahoituksen tarjoamiin kassavirtoihin. Pörssiyhtiöt investoivat vähintään yhtä paljon kuin vastaavat noteeraamattomat yritykset ja investointien tuottavuus on vähintään yhtä hyvä. Pörssiyhtiöt ovat parempia palkanmaksajia ja työllistäjiä kuin vastaavat yksityiset yritykset. Pörssiyhtiöt pystyvät maksaamaan selkeästi parempia osinkoja investointien ja muun toiminnan siitä kärsimättä, koska velkarahoituksen parempi saatavuus tai pörssiyhtiöiden suurempi halukkuus käyttää velkarahoitusta tuovat rahoitusrakenteeseen tarvittavaa joustavuutta. Tulostemme valossa arvostelu osakkeenomistajien lyhytaikaisten etujen suosimisesta muiden sidosryhmien tai pitkän aikavälin tuottavuuden kustannuksella ei ole perusteltavissa.

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.

Dimensionality of quality from a customer perspective in the wood industry

The research analyzes product quality from a customer perspective in the case of the wood products industry. Of specific interest is to understand better how environmental quality is perceived from a customer perspective. The empirical material used comprises four data-sets from Finland, Germany and the UK, collected during 1992 2004. The methods consist of a set of quantitative statistical analyses. The results indicate that perceived quality from a customer perspective can be presented using a multidimensional and hierarchical construct with tangible and intangible dimensions, that is common to different markets and products. This applies in the case of wood products but also more generally at least for some other construction materials. For wood products, tangible product quality has two main sub-dimensions: technical quality and appearance. For product intangibles, a few main quality dimensions seem be detectable: Quality of intangibles related to the physical product, such as environmental issues and product-related information, supplier-related characteristics, and service and sales personnel behavior. Environmental quality and information are often perceived as being inter-related. Technical performance and appearance are the most important considerations for customers in the case of wood products. Organizational customers in particular also clearly consider certain intangible quality dimensions to be important, such as service and supplier reliability. The high technical quality may be considered as a license to operate , but product appearance and intangible quality provide potential for differentiation for attracting certain market segments. Intangible quality issues are those where Nordic suppliers underperform in comparison to their Central-European competitors on the important German markets. Environmental quality may not have been used to its full extent to attract customers. One possibility is to increase the availability of the environment-related information, or to develop environment-related product characteristics to also provide some individual benefits. Information technology provides clear potential to facilitate information-based quality improvements, which was clearly recognized by Finnish forest industry already in the early 1990s. The results indeed indicate that wood products markets are segmented with regard to quality demands

"Innokas punikki". Hyvinkään punakaartilaisnaiset sisällissodan jälkiselvittelyissä 1918.

Hyvinkääläiset työläisnaiset ottivat vuoden 1918 sisällissotaan osaa punakaartin riveissä ruoanlaittajina, sairaanhoitajina sekä asetta kantaneina sotilaina. Valkokaartia tukemaan saapuneet saksalaissotilaat saavuttivat Hyvinkään huhtikuun 20. päivä, ja pitäjä valloitettiin. Osa hyvinkääläisnaisista oli tässä vaiheessa siirtynyt jo pohjoisemmille rintamille. Valkoiset etenivät kuitenkin voittoisasti kohti pohjoista, ja suurin osa hyvinkääläisnaisista oli antautunut 1. toukokuuta mennessä. Tämä tutkimus tarkastelee Hyvinkään punakaartilaisnaisiin kohdistuneita kuulustelututkimuksia ja toimenpiteitä sisällissodan jälkiselvittelyissä, jotka alkoivat huhtikuussa ja jatkuivat vuoden loppuun saakka. Samalla tuon esiin runsaasti uutta tietoa Hyvinkään punakaartilaisnaisten toimista sisällissodassa sekä heidän taustoistaan. Tärkeimpiä lähteitä tutkimuksessani ovat erilaiset Kansallisarkistossa säilytettävät oikeusasiakirjat: Hyvinkään pitäjän kenttäoikeuksien pöytäkirjat, viralliset esitutkintapöytäkirjat sekä valtiorikosoikeuksien ja valtiorikosylioikeuden aktit. Lisäksi olen etsinyt tietoa sodassa ja sen jälkiselvittelyissä surmansa saaneista punaisista hyvinkääläisnaisista. Tässä tärkeimpinä lähteinäni ovat olleet Suomen Sotasurmat 1914–1922 -projektin nimitiedosto sekä valkokaartin kirjanpidosta löytyneet vangitsemistiedot. Olen hyödyntänyt suuren tietomäärän käsittelyssä tilastollisia menetelmiä. Tarkastelen naisia kuitenkin paljon myös yksilötasolla, sillä juuri yksilötarinat rikastuttavat paikallishistoriallista tutkimusta. Tutkimukseni perusteella punaisiksi luokiteltuja hyvinkääläisnaisia menehtyi sisällissodan jälkiselvittelyissä 27 – heistä suurin osa Lahden ja Hämeenlinnan seudulla, missä viimeiset taistelut käytiin. Menehtyneistä naisista moni oli vasta 16–17-vuotias. Myös hyvinkääläisnaisia joutui suurille vankileireille – tässä yhteydessä tarkastelen kahden naisen vankileirimuistelmia. Kotipaikkakunnalla tutkittiin samanaikaisesti kenttäoikeuksissa 64 hyvinkääläisnaista. Kenttäoikeuksien tehtävänä oli kartoittaa punakaartilaisten toimintaa sekä heidän tietojansa paikkakunnalla ja lähiseuduilla tapahtuneista murhista sekä ryöstöistä. Kenttäoikeuksissa kuulustelluista naisista valtaosa vapautettiin lyhyen vankeuden jälkeen. Jälkiselvittelyjen virallisessa vaiheessa 116 hyvinkääläistä punakaartilaisnaista joutui kuulusteluihin. Heistä vajaa puolet oli toiminut sodan aikana erilaisissa huoltotehtävissä mm. punakaartin ruokalassa. 25 naista oli epäiltynä Hyvinkäällä huhtikuussa perustetussa aseellisessa naiskaartissa toimimisesta. Loput olivat toimineet punaisten hallinnossa tai sairaanhoitotehtävissä kotipaikkakunnalla ja rintamilla. Kuulustelujen perusteella 81 naista sai vuoden 1918 jälkipuoliskolla syytteen valtiorikosoikeudessa; heistä suurin osa avunannosta valtiopetokseen. Tutkimukseni kattaa näin kaikkiaan noin 150 hyvinkääläistä punakaartilaisnaista. Tutkimukseni valottaa heidän toimintaansa sodan aikana sekä arvioi rankaisutoimenpiteiden motiiveja. Tutkimukseni mukaan asetta kantaneisiin naisiin suhtauduttiin jälkiselvittelyissä keskimäärin hyvin ankarasti. Muiden punakaartilaisnaisten osalta rankaisutoimenpiteissä ei ollut yhtenäistä linjaa. Perunankuorinta punakaartin ruokalassa saattoi olla tuomittava rikos siinä missä kaartilaisten matkoilla liikkuminen ja ryöstetyn tavaran kätkeminen.

Sosiaalityön ammattilaiset refleksiivisinä toimijoina : tutkimus erikoistumiskoulutuksesta Margaret Archerin teorian valossa

In Finland, specialized studies in social work (professional licentiate education) were begun in the year 2000. The education is targeted at experienced social workers and leads to a licentiate degree (a degree between master s and doctorate). In this study, the experiences of members of the first study cohort, specializing in social work with children and young people, are examined. The study s theoretical frame of reference is based on the morphogenetic approach, developed by British sociologist Margaret Archer. In it, the potential powers of both an agent as well as social and cultural structures are considered important and worth taking into account. Archer sees reflexivity, a person s ability to analyze herself/himself, as an essential starting point for agency. Thanks to reflexivity, people are able to engage in internal conversations , discuss the concerns that are important to them and form agential projects . In Archer s theory, the social structures and traits of the cultural system are seen as having potential power in relation to people s agential projects; these powers can enable but also restrain the realization of the projects. On the other hand, individuals can try to review the factors affecting their agential projects and find ways of action that facilitate them. The research task is to study the self-understanding of social work professionals in the 21st century, the issues and goals professionally important for them, as well as the contexts framing the realization of these goals. The research questions are as follows: 1) What kind of internal conversations, concerns and agential projects related to their work did the professionals taking part in licentiate education bring to light? 2) What kind of enabling and restraining factors can be identified in their situations? And 3) What kind of social structures and traits related to the cultural system are connected to these factors? The research material was collected by interviewing the students in different phases of their education. In 2001 and 2004 all members of the study group (n = 25) were interviewed. In 2007, 13 students took part. The themes of the internal conversations brought to light in the interviews were divided into four broad thematic categories: professional development, the position of children in social work, multiprofessional work and structural social work. In relation to these themes the students formed different kinds of agential projects. In addition, the study reveals several cultural and social structures that have enabled but also restrained the realization of the agential projects. These structures are linked, for example, to the relations between employees and employers, students and teachers, children and adults as well as between the representatives of different professions. Working conditions which social workers often consider weak are discussed as a focal issue related to many themes. These working conditions become evident, for example, in the great imbalance which exists between the professional tasks and the amount of time that social workers have for them. Difficult situations arise when social workers feel they cannot reach the goals that are professionally important to them because of the strict external conditions of the work.

Geochemistry and petrology of the ferropicrite dikes and associated rocks of Vestfjella, western Dronning Maud Land, Antarctica

This study provides insights into the composition and origin of ferropicrite dikes (FeOtot = 13 17 wt. %; MgO = 13 19 wt. %) and associated meimechite, picrite, picrobasalt, and basalt dikes found at Vestfjella, western Dronning Maud Land, Antarctica. The dikes crosscut Jurassic Karoo continental flood basalts (CFB) that were emplaced during the early stages of the breakup of the Gondwana supercontinent ~180 Ma ago. Selected samples (31 overall from at least eleven dikes) were analyzed for their mineral chemical, major element, trace element, and Sr, Nd, Pb, and Os isotopic compositions. The studied samples can be divided into two geochemically distinct types: (1) The depleted type (24 samples from at least nine dikes) is relatively depleted in the most incompatible elements and exhibits isotopic characteristics (e.g., initial εNd of +4.8 to +8.3 and initial 187Os/188Os of 0.1256 0.1277 at 180 Ma) similar to those of mid-ocean ridge basalts (MORB); (2) The enriched type (7 samples from at least two dikes) exhibits relatively enriched incompatible element and isotopic characteristics (e.g., initial εNd of +1.8 to +3.6 and initial 187Os/188Os of 0.1401 0.1425 at 180 Ma) similar to those of oceanic island basalts. Both magma types have escaped significant contamination by the continental crust. The depleted type is related to the main phase of Karoo magmatism and originated as highly magnesian (MgO up to 25 wt. %) partial melts at high temperatures (mantle potential temperature >1600 °C) and pressures (~5 6 GPa) from a sublithospheric, water-bearing, depleted peridotite mantle source. The enriched type sampled pyroxene-bearing heterogeneities that can be traced down to either recycled oceanic crust or melt-metasomatized portions of the sublithospheric or lithospheric mantle. The source of the depleted type represents a sublithospheric end-member source for many Karoo lavas and has subsequently been sampled by the MORBs of the Indian Ocean. These observations, together with the purported high temperatures, indicate that the Karoo CFBs were formed in an extensive melting episode caused mainly by internal heating of the upper mantle beneath the Gondwana supercontinent. My research supports the view that ferropicritic melts can be generated in several ways: the relative Fe-enrichment of mantle partial melts is most readily achieved by (1) relatively low degree of partial melting, (2) high pressure of partial melting, and (3) melting of enriched source components (e.g., pyroxenite and metasomatized peridotite). Ferropicritic whole-rock compositions could also result from accumulation, secondary alteration, and fractional crystallization, however, and caution is required when addressing the parental magma composition.

Carbon dioxide and methane exchange between a boreal pristine lake and the atmosphere

Lakes serve as sites for terrestrially fixed carbon to be remineralized and transferred back to the atmosphere. Their role in regional carbon cycling is especially important in the Boreal Zone, where lakes can cover up to 20% of the land area. Boreal lakes are often characterized by the presence of a brown water colour, which implies high levels of dissolved organic carbon from the surrounding terrestrial ecosystem, but the load of inorganic carbon from the catchment is largely unknown. Organic carbon is transformed to methane (CH4) and carbon dioxide (CO2) in biological processes that result in lake water gas concentrations that increase above atmospheric equilibrium, thus making boreal lakes as sources of these important greenhouse gases. However, flux estimates are often based on sporadic sampling and modelling and actual flux measurements are scarce. Thus, the detailed temporal flux dynamics of greenhouse gases are still largely unknown. ----- One aim here was to reveal the natural dynamics of CH4 and CO2 concentrations and fluxes in a small boreal lake. The other aim was to test the applicability of a measuring technique for CO2 flux, i.e. the eddy covariance (EC) technique, and a computational method for estimation of primary production and community respiration, both commonly used in terrestrial research, in this lake. Continuous surface water CO2 concentration measurements, also needed in free-water applications to estimate primary production and community respiration, were used over two open water periods in a study of CO2 concentration dynamics. Traditional methods were also used to measure gas concentration and fluxes. The study lake, Valkea-Kotinen, is a small, humic, headwater lake within an old-growth forest catchment with no local anthropogenic disturbance and thus possible changes in gas dynamics reflect the natural variability in lake ecosystems. CH4 accumulated under the ice and in the hypolimnion during summer stratification. The surface water CH4 concentration was always above atmospheric equilibrium and thus the lake was a continuous source of CH4 to the atmosphere. However, the annual CH4 fluxes were small, i.e. 0.11 mol m-2 yr-1, and the timing of fluxes differed from that of other published estimates. The highest fluxes are usually measured in spring after ice melt but in Lake Valkea-Kotinen CH4 was effectively oxidised in spring and highest effluxes occurred in autumn after summer stratification period. CO2 also accumulated under the ice and the hypolimnetic CO2 concentration increased steadily during stratification period. The surface water CO2 concentration was highest in spring and in autumn, whereas during the stable stratification it was sometimes under atmospheric equilibrium. It showed diel, daily and seasonal variation; the diel cycle was clearly driven by light and thus reflected the metabolism of the lacustrine ecosystem. However, the diel cycle was sometimes blurred by injection of hypolimnetic water rich in CO2 and the surface water CO2 concentration was thus controlled by stratification dynamics. The highest CO2 fluxes were measured in spring, autumn and during those hypolimnetic injections causing bursts of CO2 comparable with the spring and autumn fluxes. The annual fluxes averaged 77 (±11 SD) g C m-2 yr-1. In estimating the importance of the lake in recycling terrestrial carbon, the flux was normalized to the catchment area and this normalized flux was compared with net ecosystem production estimates of -50 to 200 g C m-2 yr-1 from unmanaged forests in corresponding temperature and precipitation regimes in the literature. Within this range the flux of Lake Valkea-Kotinen yielded from the increase in source of the surrounding forest by 20% to decrease in sink by 5%. The free water approach gave primary production and community respiration estimates of 5- and 16-fold, respectively, compared with traditional bottle incubations during a 5-day testing period in autumn. The results are in parallel with findings in the literature. Both methods adopted from the terrestrial community also proved useful in lake studies. A large percentage of the EC data was rejected, due to the unfulfilled prerequisites of the method. However, the amount of data accepted remained large compared with what would be feasible with traditional methods. Use of the EC method revealed underestimation of the widely used gas exchange model and suggests simultaneous measurements of actual turbulence at the water surface with comparison of the different gas flux methods to revise the parameterization of the gas transfer velocity used in the models.

Perinatal mortality and maternal health in rural China

Background and context Since the economic reforms of 1978, China has been acclaimed as a remarkable economy, achieving 9% annual growth per head for more than 25 years. However, China's health sector has not fared well. The population health gains slowed down and health disparities increased. In the field of health and health care, significant progress in maternal care has been achieved. However, there still remain important disparities between the urban and rural areas and among the rural areas in terms of economic development. The excess female infant deaths and the rapidly increasing sex ratio at birth in the last decade aroused serious concerns among policy makers and scholars. Decentralization of the government administration and health sector reform impacts maternal care. Many studies using census data have been conducted to explore the determinants of a high sex ratio at birth, but no agreement has been so far reached on the possible contributing factors. No study using family planning system data has been conducted to explore perinatal mortality and sex ratio at birth and only few studies have examined the impact of the decentralization of government and health sector reforms on the provision and organization of maternal care in rural China. Objectives The general objective of this study was to investigate the state of perinatal health and maternal care and their determinants in rural China under the historic context of major socioeconomic reforms and the one child family planning policy. The specific objectives of the study included: 1) to study pregnancy outcomes and perinatal health and their correlates in a rural Chinese county; 2) to examine the issue of sex ratio at birth and its determinants in a rural Chinese county; 3) to explore the patterns of provision, utilization, and content of maternal care in a rural Chinese county; 4) to investigate the changes in the use of maternal care in China from 1991 to 2003. Materials and Methods This study is based on a project for evaluating the prenatal care programme in Dingyuan county in 1999-2003, Anhui province, China and a nationwide household health survey to describe the changes in maternal care utilization. The approaches used included a retrospective cohort study, cross sectional interview surveys, informant interviews, observations and the use of statistical data. The data sources included the following: 1) A cohort of pregnant women followed from pregnancy up to 7 days after birth in 20 townships in the study county, collecting information on pregnancy outcomes using family planning records; 2) A questionnaire interview survey given to women who gave birth between 2001 and 2003; 3) Various statistical and informant surveys data collected from the study county; 4) Three national household health interview survey data sets (1993-2003) were utilized, and reanalyzed to described the changes in maternity care utilization. Relative risks (RR) and their confidence intervals (CI) were calculated for comparison between parity, approval status, infant sex and township groups. The chi-square test was used to analyse the disparity of use of maternal care between and within urban and rural areas and its trend across the years in China. Logistic regression was used to analyse the factors associated with hospital delivery in rural areas. Results There were 3697 pregnancies in the study cohort, resulting in 3092 live births in a total population of 299463 in the 20 study townships during 1999-2000. The average age at pregnancy in the cohort was 25.9 years. Of the women, 61% were childless, 38% already had one child and 0.3% had two children before the current pregnancy. About 90% of approved pregnancies ended in a live birth while 73% of the unapproved ones were aborted. The perinatal mortality rate was 69 per thousand births. If the 30 induced abortions in which the gestational age was more than 28 weeks had been counted as perinatal deaths, the perinatal mortality rate would have been as high as 78 per thousand. The perinatal mortality rate was negatively associated with the wealth of the township. Approximately two thirds of the perinatal deaths occurred in the early neonatal period. Both the still birth rate and the early neonatal death rate increased with parity. The risk of a stillbirth in a second pregnancy was almost four times that for a first pregnancy, while the risk of early neonatal deaths doubled. The early neonatal mortality rate was twice as high for female as for male infants. The sex difference in the early neonatal mortality rate was mainly attributable to mortality in second births. The male early neonatal mortality rate was not affected by parity, while the female early neonatal mortality rate increased dramatically with parity: it was about six times higher for second births than for first births. About 82% early neonatal deaths happened within 24 hours after birth, and during that time, girls were almost three times more likely to die than boys. The death rate of females on the day of birth increased much more sharply with parity than that of males. The total sex ratio at birth of 3697 registered pregnancies was 152 males to 100 females, with 118 and 287 in first and second pregnancies, respectively. Among unapproved pregnancies, there were almost 5 live-born boys for each girl. Most prenatal and delivery care was to be taken care of in township hospitals. At the village level, there were small private clinics. There was no limitation period for the provision of prenatal and postnatal care by private practitioners. They were not permitted to provide delivery care by the county health bureau, but as some 12% of all births occurred either at home or at private clinics; some village health workers might have been involved. The county level hospitals served as the referral centers for the township hospitals in the county. However, there was no formal regulation or guideline on how the referral system should work. Whether or not a woman was referred to a higher level hospital depended on the individual midwife's professional judgment and on the clients' compliance. The county health bureau had little power over township hospitals, because township hospitals had in the decentralization process become directly accountable to the township government. In the township and county hospitals only 10-20% of the recurrent costs were funded by local government (the township hospital was funded by the township government and the county hospital was funded by the county government) and the hospitals collected user fees to balance their budgets. Also the staff salaries depended on fee incomes by the hospital. The hospitals could define the user charges themselves. Prenatal care consultations were however free in most township hospitals. None of the midwives made postnatal home visits, because of low profit of these services. The three national household health survey data showed that the proportion of women receiving their first prenatal visit within 12 weeks increased greatly from the early to middle 1990s in all areas except for large cities. The increase was much larger in the rural areas, reducing the urban-rural difference from more than 4 times to about 1.4 times. The proportion of women that received antenatal care visits meeting the Ministry of Health s standard (at least 5 times) in the rural areas increased sharply from 12% in 1991-1993 to 36% in 2001-2003. In rural areas, the proportion increase was much faster in less developed areas than in developed areas. The hospital delivery rate increased slightly from 90% to 94% in urban areas while the proportion increased from 27% to 69% in rural areas. The fastest change was found to be in type 4 rural areas, where the utilization even quadrupled. The overall difference between rural and urban areas was substantially narrowed over the period. Multiple logistic regression analysis shows that time periods, residency in rural or urban areas, income levels, age group, education levels, delivery history, occupation, health insurance and distance from the nearest health care facilities were significantly associated with hospital delivery rates. Conclusions 1. Perinatal mortality in this study was much higher than that for urban areas as well as any reported rate from specific studies in rural areas of China. Previous studies in which calculations of infant mortality were not based on epidemiological surveys have been shown to underestimate the rates by more than 50%. 2. Routine statistics collected by the Chinese family planning system proved to be a reliable data source for studying perinatal health, including still births, neonatal deaths, sex ratio at birth and among newborns. National Household Health Survey data proved to be a useful and reliable data source for studying population health and health services. Prior to this research there were few studies in these areas available to international audiences. 3.Though perinatal mortality rate was negatively associated with the level of township economic development, the excess female early neonatal mortality rate contributed much more to high perinatal mortality rate than economic factors. This was likely a result of the role of the family planning policy and the traditional preferences for sons, which leads to lethal neglect of female newborns and high perinatal mortality. 4. The selective abortions of female foetuses were likely to contribute most to the high sex ratio at birth. The underreporting of female births seemed to have played a secondary role. The higher early neonatal mortality rate in second-born as compared to first-born children, particularly in females, may indicate that neglect or poorer care of female newborn infants also contributes to the high sex ratio at birth or among newborns. Existing family planning policy proved not to effectively control the steadily increased birth sex ratio. 5. The rural-urban gap in service utilization was on average significantly narrowed in terms of maternal healthcare in China from 1991 to 2003. This demonstrates that significant achievements in reducing inequities can be made through a combination of socio-economic development and targeted investments in improving health services, including infrastructure, staff capacities, and subsidies to reduce the costs of service utilization for the poorest. However, the huge gap which persisted among cities of different size and within different types of rural areas indicated the need for further efforts to support the poorest areas. 6. Hospital delivery care in the study county was better accepted by women because most of women think delivery care was very important while prenatal and postnatal care were not. Hospital delivery care was more systematically provided and promoted than prenatal and postnatal care by township hospital in the study area. The reliance of hospital staff income on user fees gave the hospitals an incentive to put more emphasis on revenue generating activities such as delivery care instead of prenatal and postnatal care, since delivery care generated much profits than prenatal and postnatal care . Recommendations 1. It is essential for the central government to re-assess and modify existing family planning policies. In order to keep national sex balance, the existing practice of one couple one child in urban areas and at-least-one-son a couple in rural areas should be gradually changed to a two-children-a-couple policy throughout the country. The government should establish a favourable social security policy for couples, especially for rural couples who have only daughters, with particular emphasis on their pension and medical care insurance, combined with an educational campaign for equal rights for boys and girls in society. 2. There is currently no routine vital-statistics registration system in rural China. Using the findings of this study, the central government could set up a routine vital-statistics registration system using family planning routine work records, which could be used by policy makers and researchers. 3. It is possible for the central and provincial government to invest more in the less developed and poor rural areas to increase the access of pregnant women in these areas to maternal care services. Central government together with local government should gradually provide free maternal care including prenatal and postnatal as well as delivery care to the women in poor and less developed rural areas. 4. Future research could be done to explore if county and the township level health care sector and the family planning system could be merged to increase the effectiveness and efficiency of maternal and child care. 5. Future research could be done to explore the relative contribution of maternal care, economic development and family planning policy on perinatal and child health using prospective cohort studies and community based randomized trials.
