Strike Hard, Strike Sure - Operation Musketeer : British Military Planning during the Suez Crisis, 1956

This study analyses British military planning and actions during the Suez Crisis in 1956. It seeks to find military reasons for the change of concepts during the planning and compares these reasons with the tactical doctrines of the time. The thesis takes extensive advantage of military documents preserved in the National Archives, London. In order to expand the understanding of the exchange of views during the planning process, the private papers of high ranking military officials have also been consulted. French military documents preserved in the Service Historique de la Defence, Paris, have provided an important point of comparison. The Suez Crisis caught the British armed forces in the middle of a transition phase. The main objective of the armed forces was to establish a credible deterrence against the Soviet Union. However, due to overseas commitments the Middle East playing a paramount role because of its economic importance the armed forces were compelled to also prepare for Limited War and the Cold War. The armed forces were not fully prepared to meet this demand. The Middle Eastern garrison was being re-organised after the withdrawal from the Canal Base and the concept for a strategic reserve was unimplemented. The tactical doctrines of the time were based on experiences from the Second World War. As a result, the British view of amphibious operations and the subsequent campaigns emphasised careful planning, mastery of the sea and the air, sufficient superiority in numbers and firepower, centralised command and extensive administrative preparations. The British military had realized that Nasser could nationalise the Suez Canal and prepared an outline plan to meet this contingency. Although the plan was nothing more than a concept, it was accepted as a basis for further planning when the Canal was nationalised at the end of July. This plan was short-lived. The nominated Task Force Commanders shifted the landing site from Port Said to Alexandria because it enabled faster expansion of the bridgehead. In addition, further operations towards Cairo the hub of Nasser s power would be easier to conduct. The operational concept can be described as being traditional and was in accordance with the amphibious warfare doctrine. This plan was completely changed at the beginning of September. Apparently, General Charles Keightley, the Commander-in-Chief, and the Chairman of the Chiefs of Staff Committee developed the idea of prolonged aerial operations. The essence of the concept was to break the Egyptian will to resist by attacking the oil facilities, the transportation system and the armed forces. This victory through air concept would be supported by carefully planned psychological operations. This concept was in accordance with the Royal Air Force doctrine, which promoted a bomber offensive against selected target categories. General Keightley s plan was accepted despite suspicions at every planning level. The Joint Planning Staff and the Task Force Commanders opposed the concept from the beginning to the end because of its unpredictability. There was no information that suggested the bombing would persuade the Egyptians to submit. This problem was worsened by the fact that British intelligence was unable to provide reliable strategic information. The Task Force Commanders, who were responsible for the tactical plans, were not able to change Keightley s mind, but the concept was expanded to include a traditional amphibious assault on Port Said due to their resistance. The bombing campaign was never tested as the Royal Air Force was denied authorisation to destroy the transportation and oil targets. The Chiefs of Staff and General Keightley were too slow to realise that the execution of the plan depended on the determination of the Prime Minister. However, poor health, a lack of American and domestic support and the indecisiveness of the military had ruined Eden s resolve. In the end, a very traditional amphibious assault, which was bound to succeed at the tactical level but fail at the strategic level, was launched against Port Said.

Nuori konservatiivi : Tuure Junnila ja hänen poliittinen toimintansa vuoteen 1956

Tuure Junnila, PhD (1910-1999) was one of Finland's most renowned conservative politicians of the post-war period. Junnila is remembered primarily as a persistent opponent of Urho Kekkonen, a long-term Member of Parliament, a conspicuous opposition member and a prolific political writer. Junnila's ideologies and political views were conservative, and he is one of the most outstanding figures in the history of the National Coalition Party. Junnila also made an extensive career outside of politics, first as an economist and then as an executive of Finland's leading commercial bank Kansallis-Osake-Pankki. The Young Conservative is a partial biography written using traditional historical research methods, which examines Junnila's personal history and his activity in public life up to 1956. The study begins by investigating Junnila's background through his childhood, school years, university studies and early professional career. It also looks at Junnila's work as an economist and practical banker. Particular attention is paid to Junnila's political work, constantly focusing on the following five often overlapping areas: (1) economic policy, (2) domestic policy, (3) foreign and security policy, (4) Junnila and Urho Kekkonen, (5) Junnila, the Coalition Party and Finnish conservatism. In his economic policy, Junnila emphasised the importance of economic stability, opposed socialisation and the growth of public expenditure, defended the free market system and private entrepreneurship, and demanded tax cuts. This policy was very popular within the Coalition Party during the early 1950s, making Junnila the leading conservative economic politician of the time. In terms of domestic policy, Junnila demanded as early as the 1940s that a "third force" should be established in Finland to counterbalance the agrarian and labour parties by uniting conservative and liberal ideologies under the same roof. Foreign and security policy is the area of Junnila's political activity which is most clearly situated after the mid-1950s. However, Junnila's early speeches and writings already show a striving towards the unconditional neutrality modelled by Switzerland and Sweden and a strong emphasis on Finland's right to internal self-determination. Junnila, as did the Coalition Party as a whole, adopted a consistently critical approach towards Urho Kekkonen between 1951 and 1956, but this attitude was not as bluntly negative and all-round antagonistic as many previous studies have implied. Junnila was one of the leading Finnish conservatives of the early 1950s and in all essence his views were analogous to the general alignment of the Coalition Party at the time: conservative in ideology and general policy, and liberal in economic policy.

Idyll eller verklighet? : Albert Edelfelt och Gunnar Berndtson i det moderna genombrottets ambivalens

Idyll or Reality? Albert Edelfelt, Gunnar Berndtson and the ambivalent breakthrough of modernity Albert Edelfelt (1854-1905) and Gunnar Berndtson (1854-1895) have much in common. In this dissertation, I study their paintings of local peasants and fishermen and of the gentry’s summer in the county of Uusimaa in southern Finland, in the context of Nordic history of ideas. The breakthrough of modernity, with its attention on debating social problems, provides a novel angle into the oeuvres of the two artists. My focus is on the paintings which emerge in the collision of the public discussion of social matters and the values of the artists’ manorial milieu. The artists’ relation to the public discussion is scrutinized through two of the main topics: the question of the common people and democracy, and the question of equality between men and women. My dissertation is a contextual study which is based on the analysis of the artworks of Edelfelt and Berndtson, on their letters, and on the study of drama and fiction of their time. The notion “liberté, egalité, fraternité” is linked to the breakthrough of modernity. Both artists were aware of the ideal of equality. They used the means and the themes of contemporary art in their presentations, but their pictures contain the ideal of an earlier epoch: the hardworking, but still complacent common people. This conception of the common people is also reflected in the poems of J. L. Runeberg. Women of the late 19th century challenged woman’s primary role as wife and mother. In Edelfelt’s and Berndtson’s depictions of the gentry enjoying summer, women and children have the main role. Notwithstanding the debate of the breakthrough of modernity they depicted women almost without exception as good mothers. Their paintings often depict lazy days in the sunshine, which were, in reality, rare moments for the mistress of the house. Edelfelt’s and Berndtson’s subjects from the Uusimaa countryside coincide with the topics of the breakthrough of modernity, but both the pictures of the common people and the depictions of the gentry enjoying summer, are a retouched picture of reality, often an idyll, in which the public discussion of social matters is evident only materially or not at all.

"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 jäivät 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.

Ranskan rooli ja asema läntisessä liittoutumassa neljännen ja viidennen tasavallan vaihtumakohdassa 1956-1958

The study discusses the position of France as the United States’ ally in NATO in 1956-1958. The concrete position of France and the role that it was envisioned to have are being treated from the point of view of three participants of the Cold War: France, the United States and the Soviet Union. How did these different parties perceive the question and did these views change when the French Fourth Republic turned into the Fifth in 1958? The study is based on published French and American documents of Foreign Affairs. Because of problems with accessibility to the Soviet archival sources, the study uses reports on France-NATO relations of Pravda newspaper, the official organ of the Communist Party of the USSR, to provide information about how the Soviet side saw the question. Due to the nature and use of source material, and the chronological structure of the work, the study belongs methodologically to the research field of History of International Relations. As distinct from political scientists’ field of research, more prone to theorize, the study is characteristically a historical research, a work based on qualitative method and original sources that aims at creating a coherent narrative of the views expressed during the period covered by the study. France’s road to a full membership of NATO is being treated on the basis of research literature, after which discussions about France’s position in the Western Alliance are being chronologically traced for the period of last years of the Fourth Republic and the immediate months of coming back to power of Charles de Gaulle. Right from the spring of 1956 there can be seen aspirations of France, on one hand, to maintain her freedom of action inside the Western Alliance and, on the other, to widen the dialogue between the allies. The decision on France’s own nuclear deterrent was made already during the Fourth Republic, when it was thought to become part of NATO’s common defence. This was to change with de Gaulle. The USA felt that France still fancied herself as a great power and that she could not participate in full in NATO’s common defence because of her colonies. The Soviet Union saw the concrete position of France in the Alliance as in complete dependence on the USA, but her desired role was expressed largely in “Gaullist” terms. The expressions used by the General and the Soviet propaganda were close to each other, but the Soviet Union could not support de Gaulle without endangering the position of the French Communist Party. Between the Fourth and Fifth Republics no great rupture in content took place concerning the views of France’s role and position in the Western Alliance. The questions posed by de Gaulle had been expressed during the whole period of Fourth Republic’s existence. Instead, along with the General the weight and rhetoric of these questions saw a great change. Already in the early phase the Americans saw it possible that with de Gaulle, France would try to change her role. The rupture took place in the form of expression, rather than in its content.

Determinants of vascular cognitive impairment : White matter lesions, brain atrophy and their neuropsychological correlates

The concept of vascular cognitive impairment (VCI) covers a wide spectrum of cognitive dysfunctions related to cerebrovascular disease. Among the pathophysiological determinants of VCI are cerebral stroke, white matter lesions and brain atrophy, which are known to be important risk factors for dementia. However, the specific mechanisms behind the brain abnormalities and cognitive decline are still poorly understood. The present study investigated the neuropsychological correlates of particular magnetic resonance imaging (MRI) findings, namely, medial temporal lobe atrophy (MTA), white matter hyperintensities (WMH), general cortical atrophy and corpus callosum (CC) atrophy in subjects with cerebrovascular disease. Furthermore, the cognitive profile of subcortical ischaemic vascular disease (SIVD) was examined. This study was conducted as part of two large multidisciplinary study projects, the Helsinki Stroke Aging Memory (SAM) Study and the multinational Leukoaraiosis and Disability (LADIS) Study. The SAM cohort consisted of 486 patients, between 55 and 85 years old, with ischaemic stroke from the Helsinki University Hospital, Helsinki, Finland. The LADIS Study included a mixed sample of subjects (n=639) with age-related WMH, between 65 and 84 years old, gathered from 11 centres around Europe. Both studies included comprehensive clinical and neuropsychological assessments and detailed brain MRI. The relationships between the MRI findings and the neuropsychological test performance were analysed by controlling for relevant confounding factors such as age, education and other coexisting brain lesions. The results revealed that in elderly patients with ischaemic stroke, moderate to severe MTA was specifically related to impairment of memory and visuospatial functions, but mild MTA had no clinical relevance. Instead, WMH were primarily associated with executive deficits and mental slowing. These deficits mediated the relationship between WMH and other, secondary cognitive deficits. Cognitive decline was best predicted by the overall degree of WMH, whereas the independent contribution of regional WMH measures was low. Executive deficits were the most prominent cognitive characteristic in SIVD. Compared to other stroke patients, the patients with SIVD also presented more severe memory deficits, which were related to MTA. The cognitive decline in SIVD occurred independently of depressive symptoms and, relative to healthy control subjects, it was substantial in severity. In stroke patients, general cortical atrophy also turned out to be a strong predictor of cognitive decline in a wide range of cognitive domains. Moreover, in elderly subjects with WMH, overall CC atrophy was related to reduction in mental speed, while anterior CC atrophy was independently associated with frontal lobe-mediated executive functions and attention. The present study provides cross-sectional evidence for the involvement of WMH, MTA, general cortical atrophy and CC atrophy in VCI. The results suggest that there are multifaceted pathophysiological mechanisms behind VCI in the elderly, including both vascular ischaemic lesions and neurodegenerative changes. The different pathological changes are highly interrelated processes and together they may produce cumulative effects on cognitive decline.

Impact of Tobacco Control Policy on Smoking and Exposure to Environmental Tobacco Smoke

The aim of the study was to evaluate the impact of the Finnish tobacco control measures for reduction of smoking. First, the trends and patterns in ever smoking among adult Finns in 1978 2001 as well as the associations of trends with the Tobacco Control Act in 1976 were examined. Secondly, the impact of the 1976 TCA on the proportion of ever daily smokers in different socioeconomic groups was studied. Thirdly, the impact of the 1995 TCAA on recent trends in the prevalence of daily smoking was evaluated by gender and employment status. Fourthly, the trends of exposure to environmental tobacco smoke (ETS) at workplaces and homes were investigated. The study is based on data of the Health Behaviour among the Finnish Adult Population surveys. Among Finnish men smoking initiation declined from earlier to later cohorts, whereas among women it increased in successive birth cohorts born before 1956. The lasting differences between birth cohorts as regards ever daily smoking reflected well the impact of measures to reduce smoking in Finland in 1976. Smoking initiation in the birth cohorts (born in 1961 or later) which were in critical age as regards the risk of smoking initiation when the TCA came into force was less common than could be expected according to the trends seen in the earlier birth cohorts. Marked socioeconomic differences were found in smoking in the different birth cohorts. Smoking was more prevalent in the lower socioeconomic groups than in the higher ones, and the differences were larger in the later birth cohorts compared to the earlier ones. The differences between the birth cohorts in ever daily smoking were compatible with the hypothetical impact of the TCA in almost all socioeconomic groups, except farmers. Among men the 1976 TCA appears to have had the greatest impact on white-collar employees. Among women the effect of the act was highly significant in all socioeconomic groups. However, female smoking prevalence continues to show wide socioeconomic disparities. Daily smoking decreased among employees after the 1995 TCAA, supporting the hypothesis of the lowering impact of the amendment on daily smoking due to increased smoking cessation. No parallel change in daily smoking was found in the population without direct expose to ETS legislation (farmers, students, housewives, pensioners or unemployed). Exposure to ETS decreased markedly among non-smokers at work after the 1995 TCAA. The 1976 TCA and the 1995 TCAA were useful in controlling smoking initiation and cessation, but their impact was not equal across the population groups. The results of this study strongly suggested that tobacco control policies markedly contribute to the decrease in smoking and in exposure to environmental tobacco smoke.

The white-rot fungi Phlebia radiata and Dichomitus squalens in wood-based cultures: expression of laccases, lignin peroxidases, and oxalate decarboxylase

Basidiomycetous white-rot fungi are the only organisms that can efficiently decompose all the components of wood. Moreover, white-rot fungi possess the ability to mineralize recalcitrant lignin polymer with their extracellular, oxidative lignin-modifying enzymes (LMEs), i.e. laccase, lignin peroxidase (LiP), manganese peroxidase (MnP), and versatile peroxidase (VP). Within one white-rot fungal species LMEs are typically present as several isozymes encoded by multiple genes. This study focused on two effi cient lignin-degrading white-rot fungal species, Phlebia radiata and Dichomitus squalens. Molecular level knowledge of the LMEs of the Finnish isolate P. radiata FBCC43 (79, ATCC 64658) was complemented with cloning and characterization of a new laccase (Pr-lac2), two new LiP-encoding genes (Pr-lip1, Pr-lip4), and Pr-lip3 gene that has been previously described only at cDNAlevel. Also, two laccase-encoding genes (Ds-lac3, Ds-lac4) of D. squalens were cloned and characterized for the first time. Phylogenetic analysis revealed close evolutionary relationships between the P. radiata LiP isozymes. Distinct protein phylogeny for both P. radiata and D. squalens laccases suggested different physiological functions for the corresponding enzymes. Supplementation of P. radiata liquid culture medium with excess Cu2+ notably increased laccase activity and good fungal growth was achieved in complex medium rich with organic nitrogen. Wood is the natural substrate of lignin-degrading white-rot fungi, supporting production of enzymes and metabolites needed for fungal growth and the breakdown of lignocellulose. In this work, emphasis was on solid-state wood or wood-containing cultures that mimic the natural growth conditions of white-rot fungi. Transcript analyses showed that wood promoted expression of all the presently known LME-encoding genes of P. radiata and laccase-encoding genes of D. squalens. Expression of the studied individual LME-encoding genes of P. radiata and D. squalens was unequal in transcript quantities and apparently time-dependent, thus suggesting the importance of several distinct LMEs within one fungal species. In addition to LMEs, white-rot fungi secrete other compounds that are important in decomposition of wood and lignin. One of these compounds is oxalic acid, which is a common metabolite of wood-rotting fungi. Fungi produce also oxalic-acid degrading enzymes of which the most widespread is oxalate decarboxylase (ODC). However, the role of ODC in fungi is still ambiguous with propositions from regulation of intra and extracellular oxalic acid levels to a function in primary growth and concomitant production of ATP. In this study, intracellular ODC activity was detected in four white-rot fungal species, and D. squalens showed the highest ODC activity upon exposure to oxalic acid. Oxalic acid was the most common organic acid secreted by the ODC-positive white-rot fungi and the only organic acid detected in wood cultures. The ODC-encoding gene Ds-odc was cloned from two strains of D. squalens showing the first characterization of an odc-gene from a white-rot polypore species. Biochemical properties of the D. squalens ODC resembled those described for other basidiomycete ODCs. However, the translated amino acid sequence of Ds-odc has a novel N-terminal primary structure with a repetitive Ala-Ser-rich region of ca 60 amino acid residues in length. Expression of the Ds-odc transcripts suggested a constitutive metabolic role for the corresponding ODC enzyme. According to the results, it is proposed that ODC may have an essential implication for the growth and basic metabolism of wood-decaying fungi.

Characterization of lignin-modifying enzymes of the selective white-rot fungus Physisporinus rivulosus

White-rot fungi are wood degrading organisms that are able to decompose all wood polymers; lignin, cellulose and hemicellulose. Especially the selective white-rot fungi that decompose preferentially wood lignin are promising for biopulping applications. In biopulping the pretreatment of wood chips with white-rot fungi enhances the subsequent pulping step and substantially reduces the refining energy consumption in mechanical pulping. Because it is not possible to carry out biopulping in industrial scale as a closed process it has been necessary to search for new selective strains of white-rot fungi which naturally occur in Finland and cause selective white-rot of Finnish wood raw-material. In a screening of 300 fungal strains a rare polypore, Physisporinus rivulosus strain T241i isolated from a forest burn research site, was found to be a selective lignin degrader and promising for the use in biopulping. Since selective lignin degradation is apparently essential for biopulping, knowledge on lignin-modifying enzymes and the regulation of their production by a biopulping fungus is needed. White-rot fungal enzymes that participate in lignin degradation are laccase, lignin peroxidase (LiP), manganese peroxidase (MnP), versatile peroxidase (VP) and hydrogen peroxide forming enzymes. In this study, P. rivulosus was observed to produce MnP, laccase and oxalic acid during growth on wood chips. In liquid cultures manganese and veratryl alcohol increased the production of acidic MnP isoforms detected also in wood chip cultures. Laccase production by P. rivulosus was low unless the cultures were supplemented with sawdust and charred wood, the components of natural growth environment of the fungus. In white-rot fungi the lignin-modifying enzymes are typically present as multiple isoforms. In this study, two MnP encoding genes, mnpA and mnpB, were cloned and characterized from P. rivulosus T241i. Analysis of the N-terminal amino acid sequences of two purified MnPs and putative amino acid sequence of the two cloned mnp genes suggested that P. rivulosus possesses at least four mnp genes. The genes mnpA and mnpB markedly differ from each other by the gene length, sequence and intron-exon structure. In addition, their expression is differentially affected by the addition of manganese and veratryl alcohol. P. rivulosus produced laccase as at least two isoforms. The results of this study revealed that the production of MnP and laccase was differentially regulated in P. rivulosus, which ensures the efficient lignin degradation under a variety of environmental conditions.

Degradation of lignin and other 14C-labelled compounds in compost and soil with an emphasis on white-rot fungi

Puu, ruohokasvit ja näistä tehdyt tuotteet kuten mekaanisesta massasta valmistettu sanomalehtipaperi sisältävät ligniiniä, joka hajoaa yleensä hyvin hitaasti luonnossa. Valkolahosienet hajottavat ligniiniä tehokkaimmin, ja koska niiden tuottamat entsyymit hajottavat myös muita vaikeasti hajoavia yhdisteitä, voidaan valkolahosienten avulla mahdollisesti puhdistaa saastuneita maita. Tässä työssä haluttiin selvittää, säilyttävätkö valkolahosienet (Abortiporus biennis, Bjerkandera adusta, Dichomitus squalens, Phanerochaete chrysosporium, Phanerochaete sordida, Phlebia radiata, Pleurotus ostreatus, Trametes hirsuta ja Trametes versicolor) aktiivisuutensa ja kasvavatko ne maassa. Aktiivisuutta mitattiin seuraamalla sienten synteettisen ligniinin (14C-DHP) hajotuskykyä. T. versicolor (silkkivyökääpä) osoittautui tehokkaimmaksi ligniinin hajottajaksi ja sen pentakloorifenolin (PCP) hajotuskykyä tutkittiin erillisessä kokeessa. Entiset tai pitkään käytössä olleet saha-alueet ovat yhä saastuneet puun käsittelyaineista peräisin olevilla kloorifenoleilla. Biohajoavien muovien kehitystyö sekä kompostoinnin yleistyminen jätteiden käsittelymenetelmänä ovat luoneet tarpeen materiaalien biohajoavuuden määrittämiseen. Euroopan standardisoimisjärjestön (CEN) kontrolloidussa kompostitestissä biohajoavuus määritetään materiaalin hajoamisen aikana muodostuvan hiilidioksidin perusteella. Hiilidioksidin tuotto mitataan sekä näytettä sisältävästä kompostista että kompostista ilman näytettä, ja tällöin oletetaan, että kompostin orgaaninen aines molemmissa komposteissa (tausta) tuottaa yhtä paljon hiilidioksidia. Testin puutteeksi saattaa osoittautua kompostissa tai maassa esiintyvä "priming effect". Tällä tarkoitetaan materiaalin lisäämisen jälkeen esiintyvää epänormaalin suurita tai pientä hiilidioksidin muodostusta, minkä seurauksena testin tulosksena saatava biohajoavuus on virheellinen. Ligniinin hajotessa muodostuu enemmän humusta kuin hiilidioksidia, koska ligniini on humuksen tärkein lähtöaine. Näin ollen ligniiniä sisältävät paperituotteet saattavat testin mukaan vaikuttaa biologisesti hajoamattomilta. Valkolahosienet hajottivat 4-23% ligniinistä hiilidioksidiksi ja T. versicolor 29% PCP:sta. Kompostissa ligniini hajosi hiilidioksidiksi 58°C:ssa huomattavasti vähemmän (8%) kuin lämpötiloissa 35°C ja 50°C (23-24%). Kompostin todennäköisesti tärkeimpien ligniinin hajottajien, termofiilisten sienten, tyypillinen optimilämpötila on 45°C, eivätkä ne ole enää aktiivisia 58°C:ssa. Sekä maassa että kompostissa ligniini sitoutui kuitenkin suurimmaksi osaksi humukseen. Valkolahosienet hajottivat sekä humukseen sitoutunutta ligniiniä että PCP:ia, mutta kompostin sekapopulaatio ei tähän pystynyt, ja ligniiniä sitoutui humukseen yhä enemmän kompostoinnin aikana. T. versicolor hajotti PCP:ia tehokkaasti, eikä se tuottanut myrkyllisiä kloorianisoleja, joita jotkut valkolahosienet saattavat muodostaa kloorifenoleista. Priming effect ilmiötä tutkittiin eri ikäisissä ja kypsyydeltään erilaisissa komposteissa. Kompostit erosvat toisistaan myös hajoamattoman jätteen määrän ja mikrobipopulaation suhteen. Negatiivinen priming effect havaittiin kaikissa epästabiileissa komposteissa (ikä enintään 6 kk), ja sen lisäksi yhdessä näistä komposteista positiivinen priming effect kokeen lopussa. Stabiileissa komposteissa (ikä vähintään 6 kk) ilmiötä ei sen sijaan havaittu. Epästabiileissa komposteissa biohajoavuudelle saadut tulokset eivät siis ole luotettavia. Työn tulosten perusteella valkolahosienet, ja erityisesti T. versicolor, ovat lupaavia saastuneen maan puhdistukseen, joskin sienirihmaston mahdollisuudet säilyä aktiivisena maan alkuperäisen mikrobipopulaation kanssa täytyy vielä selvittää. Kompostin sekapopulaatio, joka ei sisällä valkolahosieniä, hajotti ligniiniä yllättävän tehokkaasti termofiilisille sienille sopivissa lämpötiloissa, vaikka ligniini sitoutuikin pääasiallisesti humukseen. Kompostin kypsyys osoittautui tärkeäksi tekijäksi kontrolloidun kompostitestin onnistumisen kannalta. Priming effect ilmiön välttämiseksi on varmistettava, että testissä käytetty komposti on riittävän kypsä. Kompostien mikrobipopulaation koostumusta kompostoinnin eri vaiheissa tulisi tarkemmin selvittää, koska stabiilien ja epästabiilien kompostien ero aiheutui todennäköisesti populaatioiden rakenteessa vallitsevista eroista. Näin myös priming effect ilmiön syyt voitaisiin selittää paremmin.

Holistic Spirituality in the Thinking of Ellen White

Spiritualiteetti viittaa syvälliseen, inhimilliseen ulottuvuuteen ja ominaisuuteen, jonka tarkka määritteleminen on haasteellista, ellei mahdotonta. Sitä vastaa yhtäältä uskonnollisuuden kautta toteutuva, elämän tarkoitukseen ja syvemmän olemuksen etsintään liittyvä hengellisyys, mutta toisaalta myös kaikkea muuta hengen viljelyä ja mielekkään olemisen tavoittelua tarkoittava henkisyys. John Swintonin mukaan hengen ulottuvuus on se inhimilliseen olemukseen kuuluva, dynaaminen elinvoima, joka virkistää ja elävöittää ihmistä ja motivoi häntä etsimään Jumalaa, arvoja, merkitystä, tarkoitusta ja toivoa. Tämä tutkimus nostaa tarkastelun kohteeksi kokonaisvaltaisen hengellisyyden, jolloin huomio kiinnitetään niihin sidoksiin, joiden kautta hengen ulottuvuus liittyy muihin inhimillisen elämän olennaisiin toimintoihin ja näkökulmiin. Tällaisia ovat 1) ajattelu 2) teot ja käytännön toiminta 3) suhteet ja vuorovaikutusverkostot 4) tunteet ja kanssakäymistä ohjaavat asenteet 5) olemassaolon ja olemisen ulottuvuudet. Kokemusten merkitys, arvo ja mielekkyys hahmottuvat juuri hengen alueella, toisin sanoen sisäisesti, hengellisenä ja henkisenä asiana. Tutkimusmateriaalina tässä tutkimuksessa on amerikkalaisen vuosina 1827 1915 eläneen Ellen Whiten kuusi myöhäiskauden teosta vuosilta 1892 1905 ja tutkimusmenetelmänä on käytetty systemaattista analyysiä. Olennaista Whiten tavassa käsitellä uskonnon harjoitukseen liittyviä aiheita on hänen käytännöllinen ja elämän arkeen kiinteästi niveltyvä otteensa. Tutkimus paljastaa, että Martti Lutherin käsitykset ovat merkittävästi vaikuttaneet Whiten ajatteluun. Lähteistä paljastuu samankaltaisuutta hänen näkemystensä ja uusimman suomalaisen Luther-tutkimuksen Martti Lutherin tuotannosta esiin nostaman ajattelutavan välillä. Vaikka teologisen oppineisuuden kannalta White ja Luther ovat eri tasoilla, kummankin käsitys ihmisen ja Jumalan välisen suhteen perusolemuksesta on samankaltainen: Lähtökohtana sille on Jumalan rakkaus ja hänen armostaan lähtenyt toiminta. Toiseksi, ihmisen ja Kristuksen välinen, olemuksellinen yhteys, unio , on perustana sille, että Jumala hyväksyy ihmisen ja huolehtii hänestä nyt ja ikuisesti. Kolmanneksi, tämä ihmisen ja Kristuksen liittoutuminen ja yhdistyminen ilmenee yhteistoimintana ja kumppanuutena yhteisten tavoitteiden saavuttamiseksi maailmassa. White korostaa ihmisen ja Kristuksen välisen hengellisen suhteen vuorovaikutteista ja toiminnallista luonnetta, joka tulee ilmi epäitsekkyytenä, toisten ihmisten ja heidän tarpeittensa huomioimisena sekä myötätuntona ja kykynä asettua toisen asemaan. Terveellistä elämäntapaa ja kasvatusta koskevat ajatuksensa White liittää siihen laaja-alaiseen näkemykseen hengellisyydestä, jonka tavoitteena on ihmisen kokonaisvaltainen hyvinvointi. Hän ei näe spiritualiteettia elämän arjesta irrallisena tai erillisenä saarekkeena, vaan ihmistä kaikessa ohjaavana, voimaannuttavana ja mielekkyyttä tuottavana, ensisijaisena ulottuvuutena. Tutkimuksen kuluessa myös Whiten usein käyttämät Jumalalle antautumisen ja luonteen käsitteet nousevat tarkastelun kohteiksi. Hänen mukaansa ihminen ei tahdonponnistuksillaan yksin pysty tavoittamaan Jumalaa vaan hänen on lakattava Jumalan rakastavan kutsun edessä itse tahtomasta ja suostuttava liittymään Jumalan tahtoon ja tarkoitukseen. Tämä liittyy siihen sisäiseen muutokseen, jota White kuvaa luonteen käsitteen avulla. Jumalan armon vaikuttama tahdon uudelleen suuntaaminen muuttaa ihmisen olemusta, arvoja, asennoitumisen tapaa ja myötätuntoisen vuorovaikutuksen kykyä niin ettei ihminen ole enää aivan sama kuin ennen. Kysymys on toisaalta yhtäkkisestä ja kertakaikkisesta olemuksellisesta muuttumisesta, mutta samalla myös hiljaisesta, elämänmittaisesta kasvusta ja kypsymisestä. Juuri luonteen käsitteen avulla White kuvaa hengellisyyttä ja siihen kuuluvaa sisästä matkaa. Tässä tutkimuksessa spiritualiteettia lähestytään yleisinhimillisenä piirteenä ja ominaisuutena, jolloin huomio ei ole ensisijaisesti yksittäisissä opillisissa käsityksissä tai uskonnollisuuden harjoittamisen muodoissa. Tarkoituksena on luoda kokoava rakenne, jonka puitteissa holistinen spiritualiteetti voidaan selkeämmin hahmottaa ja yksilöidymmin ymmärtää.

The Soviet Union, Finland and the Cold War : The Finnish Card in Soviet Foreign Policy, 1956-1959

From the Soviet point of view the actual substance of Soviet-Finnish relations in the second half of 1950s clearly differed from the contemporary and later public image, based on friendship and confidence rhetoric. As the polarization between the right and the left became more underlined in Finland in the latter half of the 1950s, the criticism towards the Soviet Union became stronger, and the USSR feared that this development would have influence on Finnish foreign policy. From the Soviet point of view, the security commitments of FCMA-treaty needed additional guarantees through control of Finnish domestic politics and economic relations, especially during international crises. In relation to Scandinavia, Finland was, from the Soviet point of view, the model country of friendship or neutrality policy. The influence of the Second Berlin Crisis or the Soviet-Finnish Night Frost Crisis in 1958-1959 to Soviet policy towards Scandinavia needs to be observed from this point of view. The Soviet Union used Finland as a tool, in agreement with Finnish highest political leadership, for weakening of the NATO membership of Norway and Denmark, and for maintaining Swedish non-alliance. The Finnish interest to EFTA membership in the summer of 1959, at the same time with the Scandinavian countries, seems to have caused a panic reaction in the USSR, as the Soviets feared that these economic arrangements would reverse the political advantages the country had received in Finland after the Night Frost Crisis. Together with history of events, this study observes the interaction of practical interests and ideologies, both in individuals and in decision-making organizations. The necessary social and ideological reforms in the Soviet Union after 1956 had influence both on the legitimacy of the regime, and led to contradictions in the argumentation of Soviet foreign policy. This was observed both in the own camp as well as in the West. Also, in Finland a breakthrough took place in the late 1950's: as the so-called counter reaction lost to the K-line, "a special relationship" developed with the Soviet Union. As a consequence of the Night Frost Crisis the Soviet relationship became a factor decisively defining the limits of domestic politics in Finland, a part of Finnish domestic political argumentation. Understood from this basis, finlandization is not, even from the viewpoint of international relations, a special case, but a domestic political culture formed by the relationship between a dominant state, a superpower, and a subordinate state, Finland.
