Pro gradu -tutkielmani käsittelee kääntämistä vieraan kielen opetuksessa nykyään sekä kääntämisen ja käännöstieteen mahdollisuuksia vieraan kielen opetuksen kehittämiseen. Aihe on mielenkiintoinen, sillä siitä ei juurikaan ole tutkimusta, sekä se on myös yhteiskunnallisesti merkittävä. Ennen kaikkea työn on tarkoitus toimia keskustelunavauksen tälle aihepiirille. Materiaalina on käytetty lukion saksan kielen oppimateriaaleja Weitere Wege (A1-kieli), Neue Adresse (B2-kieli) ja Kurz und gut (B3-kieli) sekä saksan ylioppilastutkintoja vuosilta 1998-2005 (sekä pitkä että lyhyt saksa), jotka yhdessä edustavat tämän hetkistä lukion saksan kielen opetusta. Koska lukion oppimateriaalit ja ylioppilastutkinnot eivät ainakaan päällisin puolin eroa eri vieraiden kielten välillä toisistaan, koskevat päätelmät kattavasti koko lukion vieraan kielten opetusta. Materiaalia ja vieraan kielten opetusta tutkitaan tässä työssä pääasiallisesti tehtävien kautta. Oppimateriaalin tehtävät on kategorisoitu yhdeksään tehtävätyyppiin, joista 'kääntäminen' on yksi. Muut tehtävätyypit ovat 'ääneenlukeminen ja ääntäminen', 'maantuntemus ja kulttuuri', 'luetunymmärätäminen', 'kuullunymmärtäminen', 'tekstintuottaminen', 'suulliset harjoitukset', 'sanasto' sekä 'kielioppi ja rakenne'. Ylioppilastutkinnoissa esiintyvät tehtävätyypit 'luetunymmärätäminen', 'kuullunymmärtäminen', 'tekstintuottaminen' sekä 'kielioppi ja rakenne', eikä käännöstehtäviä ole tutkituissa kokeissa lainkaan. Oppimateriaalin ja ylioppilastutkinnon tehtäviin liittyen esitetään kvantitatiivisia tuloksia sekä anlysoidaan niiden kautta vieraan kielen opetuksen nykytilaa. Pääasiallinen analyysi keskittyy käännöstehtävien kvalitatiiviseen tutkimiseen, joilloin voidaan todeta, että nämä tehtävät edustavat oikeastaan merkkien kääntämistä, eivät merkityksen kääntämistä. Nämä käännöstehtävät ovat sisällöiltään luetun ymmärtämisen, tekstintuottamisen, sanaston sekä kieliopin ja rakenteen tehtäviä, eikä niillä ole mitään tekemistä kääntämisen kanssa nykypäivän käännöstieteellisessä merkityksessä. Siten kääntäminen käännösmielessä voisi tarjota vieraan kielen opetukselle uuden oppimismetodin, jossa ennen kaikkea kulttuurien välisen viestinnän aspektit olisivat huomioitu. Kääntämiseen liittyvistä osataidoista, mm. tutkimis- ja analyysitaidoista, voisi olla etua kielten opetukselle tulevaisuudessa.

This dissertation explores the role of the German minister to Helsinki, Wipert von Blücher (1883-1963), within the German-Finnish relations of the late 1930s and the Second World War. Blücher was a key figure – and certainly one of the constants – within German Finland policy and the complex international diplomacy surrounding Finland. Despite representing Hitler’s Germany, he was not a National Socialist in the narrower sense of the term, but a conservative civil servant in the Wilhelmine tradition of the German foreign service. Along with a significant number of career diplomats, Blücher attempted to restrict National Socialist influence on the exercise of German foreign policy, whilst successfully negotiating a modus vivendi with the new regime. The study of his political biography in the Third Reich hence provides a highly representative example of how the traditional élites of Germany were caught in an cycle of conformity and, albeit tacit, opposition. Above all, however, the biographical study of Blücher and his behaviour offers an hitherto unexplored approach to the history of the German-Finnish relations. His unusually long tenure in Helsinki covered the period leading up to the so-called Winter War, which left Blücher severely distraught by Berlin’s effectively pro-Soviet neutrality and brought him close to resigning his post. It further extended to the German-Finnish rapprochement of 1940/41 and the military cooperation of both countries from mid-1941 to 1944. Throughout, Blücher developed a diverse and ambitious set of policy schemes, largely rooted in the tradition of Wilhelmine foreign policy. In their moderation and commonsensical realism, his designs – indeed his entire conception of foreign policy – clashed with the foreign political and ideological premises of the National Socialist regime. In its theoretical grounding, the analysis of Blücher’s political schemes is built on the concept of alternative policy and indebted to A.J.P. Taylor’s definition of dissent in foreign policy. It furthermore rests upon the assumption, introduced by Wolfgang Michalka, that National Socialist foreign policy was dominated by a plurality of rival conceptions, players, and institutions competing for Hitler’s favour (‘Konzeptionen-Pluralismus’). Although primarily a study in the history of international relations, my research has substantially benefited from more recent developments within cultural history, particularly research on nobility and élites, and the renewed focus on autobiography and conceptions of the self. On an abstract level, the thesis touches upon some of the basic components of German politics, political culture, and foreign policy in the first half of the 20th century: national belonging and conflicting loyalties, self-perception and representation, élites and their management of power, the modern history of German conservatism, the nature and practice of diplomacy, and, finally, the intricate relationship between the ethics of the professional civil service and absolute moral principles. Against this backdrop, the examination of Blücher’s role both within Finnish politics and the foreign policy of the Third Reich highlights the biographical dimension of the German-Finnish relationships, while fathoming the determinants of individual human agency in the process.

Common mode voltage (CMV) variations in PWM inverter-fed drives generate unwanted shaft and bearing current resulting in early motor failure. Multilevel inverters reduce this problem to some extent, with higher number of levels. But the complexity of the power circuit increases with an increase in the number of inverter voltage levels. In this paper a five-level inverter structure is proposed for open-end winding induction motor (IM) drives, by cascading only two conventional two-level and three-level inverters, with the elimination of the common mode voltage over the entire modulation range. The DC link power supply requirement is also optimized by means of DC link capacitor voltage balancing, with PWM control., using only inverter switching state redundancies. The proposed power circuit gives a simple power bits structure.

A restricted maximum likelihood analysis applied to an animal model showed no significant differences (P > 0.05) in pH value of the longissimus dorsi measured at 24 h post-mortem (pH24) between high and low lines of Large White pigs selected over 4 years for post-weaning growth rate on restricted feeding. Genetic and phenotypic correlations between pH24 and production and carcass traits were estimated using all performance testing records combined with the pH24 measurements (5.05-7.02) on slaughtered animals. The estimate of heritability for pH24 was moderate (0.29 ± 0.18). Genetic correlations between pH24 and production or carcass composition traits, except for ultrasonic backfat (UBF), were not significantly different from zero. UBF had a moderate, positive genetic correlation with pH24 (0.24 ± 0.33). These estimates of genetic correlations affirmed that selection for increased growth rate on restricted feeding is likely to result in limited changes in pH24 and pork quality since the selection does not put a high emphasis on reduced fatness.

Atherosclerosis is a disease of the arteries; its characteristic features include chronic inflammation, extra- and intracellular lipid accumulation, extracellular matrix remodeling, and an increase in extracellular matrix volume. The underlying mechanisms in the pathogenesis of advanced atherosclerotic plaques, that involve local acidity of the extracellular fluid, are still incompletely understood. In this thesis project, my co-workers and I studied the different mechanisms by which local extracellular acidity could promote accumulation of the atherogenic apolipoprotein B-100 (apoB-100)-containing plasma lipoprotein particles in the inner layer of the arterial wall, the intima. We found that lipolysis of atherogenic apoB-100-containing plasma lipoprotein particles (LDL, IDL, and sVLDL) by the secretory phospholipase A2 group V (sPLA2-V) enzyme, was increased at acidic pH. Also, the binding of apoB-100-containing plasma lipoprotein particles to human aortic proteoglycans was dramatically enhanced at acidic pH. Additionally, lipolysis by sPLA2-V enzyme further increased this binding. Using proteoglycan-affinity chromatography, we found that sVLDL lipoprotein particles consist of populations, differing in their affinities toward proteoglycans. These populations also contained different amounts of apolipoprotein E (apoE) and apolipoprotein C-III (apoC-III); the amounts of apoC-III and apoE per particle were highest in the population with the lowest affinity toward proteoglycans. Since PLA2-modification of LDL particles has been shown to change their aggregation behavior, we also studied the effect of acidic pH on the monolayer structure covering lipoprotein particles after PLA2-induced hydrolysis. Using molecular dynamics simulations, we found that, in acidity, the monolayer is more tightly packed laterally; moreover, its spontaneous curvature is negative, suggesting that acidity may promote lipoprotein particles fusion. In addition to extracellular lipid accumulation, the apoB-100-containing plasma lipoprotein particles can be taken up by inflammatory cells, namely macrophages. Using radiolabeled lipoprotein particles and cell cultures, we showed that sPLA2-V-modification of LDL, IDL, and sVLDL lipoproteins particles, at neutral or acidic pH, increased their uptake by human monocyte-derived macrophages.

Acidity in terms of pH and titratable acids influences the texture and flavour of fermented dairy products, such as Kefir. However, the methods for determining pH and titratable acidity (TA) are time consuming. Near infrared (NIR) spectroscopy is a non-destructive method, which simultaneously predicts multiple traits from a single scan and can be used to predict pH and TA. The best pH NIR calibration model was obtained with no spectral pre-treatment applied, whereas smoothing was found to be the best pre-treatment to develop the TA calibration model. Using cross-validation, the prediction results were found acceptable for both pH and TA. With external validation, similar results were found for pH and TA, and both models were found to be acceptable for screening purposes.

The continuous mutual transfer of knowledge and skills within work teams is increasingly important for organizational practice. According to the situational and experience-based approaches of applied learning research, certain individual and social prerequisites have to be met for successful learning in teams. In a field study at an automobile production site, it was investigated which personal characteristics of multipliers and which characteristics of teams are related to the performance of multipliers in 31 teams with 291 coworkers. Using multi-level analyses (HLM), the amount of variance explained by the predictor variables in teaching success of multipliers and learning success of coworkers was examined. Results showed that multipliers' conscientiousness and team cohesion were related to teaching success of multipliers; extraversion and team cohesion were related to the learning success of coworkers. In closing, the scientific and practical implications for the investigation and promotion of work-based learning processes in teams are discussed.

Bacterial proliferation in both vase solutions and in cut flower stems has been implicated in reducing the vase life of numerous genera. Boronia heterophylla F. Muell. (Red Boronia) vase life was assessed at two stages of floral maturity for nine vase solution treatments covering a pH range of 2.5-5.7. Vase life for advanced harvest maturity stems ranged from 4.2 d in 10 mM citric acid + 50 mg L-1 chlorine (pH 2.5) to 12.9 d after STS pulsing (pH 5.7). For normal harvest maturity stems, the corresponding range was 5.8-19.0 d, respectively. Vase solutions containing 50 mg L-1 chlorine biocide resulted in decreased longevity. In contrast, pulsing with the ethylene-binding inhibitor, STS, significantly increased vase life. The number of bacteria in the vase solutions after 11 d was determined in stems of advanced maturity. The solution with the greatest number of bacteria, 4.0 x 10(10) cfu mL(-1), was water used after STS pulsing and in which the flowers lasted longest. Vase solution bacteria were enumerated on days 0,3, 6, 9 and 12 of the vase period with stems of normal harvest maturity. There was no relationship between vase life and vase solution bacterial numbers ((R) over bar (2) = 0.000). Moreover, there was a negative relationship between numbers of bacteria in basal 0-5 cm stem segments and vase life. As no correlations were evident between longevity and either the pH or vase solution bacterial numbers, B. heterophylla vase life was evidently limited principally by ethylene action.
