Agriculture accounts for 9 per cent of the total surface area of Finland and generates the greatest single nutrient input to Finnish watercourses. Since agricultural activity is scattered throughout the whole country its effects in lakes are less pronounced than those of domestic and industrial effluents. On the other hand, point source phosphorus loading of lakes and rivers decreased significantly during the nineteen-seventies. Phosphorus is the nutrient which primarily limits production in most Finnish lakes. The availability of phosphorus in agricultural runoff waters is therefore a crucial question in the evaluation of the eutrophicating effects of agriculture. Our results indicated that in runoff waters available phosphorus can be 60-70 per cent of the total phosphorus. However, the concentrations of available P were so low that they could be achieved in Finnish lakes of low ionic concentration through simple chemical desorption without the assistance of the algal uptake. The utilization of the spring maximum of runoff phosphorus in lakes would thus not depend on the concurrence of the maxima of loading and algal growth.

In this article two major volumes with Chinese paper cut art by Fan Pu (Paula Fan) are reviewed. In her work it becomes clear how a traditional type of folk art can be transformed by using new techniques and material. By doing so, Fan Pu is able to make modern Christian art, which hopefully also appeals to present-day Chinese people. Herself being an evangelical Christian, she interestingly also uses sayings by pre-Christian Chinese sages like Confucius in her art; their wisdom can be seen as a kind of preparatio evangelica. The two works, analyzed here, together form a catalog of her work so far, from the nineteen seventies till now.

<p>Artykuł w syntetyczny sposób omawia najważniejsze zjawiska filmu eksperymentalnego w kontekście pojęcia i praktyki sztuki neoawangardowej od II połowy lat 60. do połowy lat 70. XX wieku. Na początku przypomniana została pierwsza i druga faza rozwoju filmu eksperymentalnego w związku z istnieniem tzw. Wielkiej Awangardy oraz z działalnością jej kontynuatorów po Ii wojnie światowej w USA. Nastepnie zdefiniowane zostało pojęcie neoawangardy w odniesieniu do ujęcia, które zparoponował Frank Popper. W dalszej części artykułu jego autor omawia zasady oraz najważniejsze przykłady filmów neoawangardowych m. in: film strukturalny, kino porzeszone, intermedia. Ważną częścią artykułu jest przedstawienie początków, idei oraz najważniejszych rodzajów sztuki video. W artykule omówione zostały filmy takich autorów jak m. in. Paul Sharits, Peter Kubelka, Peter Campus, Bill Viola i innych.</p><p> </p><strong>Film Neo-Avant-garde and the Beginnings of Video Art</strong><p>SUMMARY</p><p>The article comprehensively discusses the most important phenomena of experimental film in the context of the concept and practice of neo-avant-garde art from the latter half of the nineteen-sixties to the mid-nineteen-seventies. The paper begins by referring to the first and second phase of the development of experimental film in connection with the existence of the so-called Great Avant-garde and the activity of its continuators after World War Two in the USA. The text then defines the concept of neo-avant-garde in relation to the interpretation proposed by Frank Popper. The article then discusses the principles and the most important examples of neo-avant-garde films, inter alia structural film, widened cinema, or intermedia. An important part of the article is the presentation of the beginnings, idea and the major types of video art. The paper also discusses the films by such authors as inter alia Paul Sharits, Peter Kubelka, Peter Campus, Bill Viola, and others.</p>

Fra livsoplysning og livsfilosofiske perspektiver- et uddannelsesmæssigt modsvar til tidens fokus på kompetenceudvikling[From ‘Life-enlightenment' and ‘life-philosophical’ perspectives – a pedagogic challenge to the contemporary focus on ‘competence-development ’]By Lene FrølundViewed in the context of education, competence-development [kompetenceudvikling] is the sign of the times. Within current educational research, the concept of ‘competence’ seems to have been identified as post modernity’s answer to the question of how individuals can learn to bring and keep themselves abreast of development in a complex knowledge- and informationbased society which imposes requirements of control, skillful steering and readiness to adapt.The pedagogic theme which sets the agenda in this debate on post-modern educational ideals is emancipation-pedagogy [frigørelsespædagogik], which has its roots in the Frankfurt School and Critical Theory, and which reaches back to the ideals of Liberty and Reason in the Age of Enlightenment. Since the nineteen-seventies emancipation-pedagogy has almost exclusively set the pedagogic agenda in Denmark. With its background in a philosophy based upon scientific rationalism, it has made its essential objective the development of the pupil’s critical sense. Thus political education and, subsumed in this, the development of a democratic disposition [det demokratiske sindelag] have been prioritised, at the cost of a strengthening of the philosophical disposition [det filosofiske sindelag] - as in the discussion of the perennial questions of existence.It is this rational-scientific outlook upon education with which Regner Birkelund takes issue in his book, Livs-Oplysning [Life-enlightenment]. With a background in N. F. S. Grundtvig and K. E. Løgstrup his aim is to enquire how one may combine a vocation-orientated education with a humane educational orientation. The enquiry is centred about a concrete example within nursing - a pedagogic experiment which took place at Testrup Højskole between 1927 and 1975. This folk-highschool featured a course preliminary to the school of nursing where future nurses were to be taught general highschool subjects together with specialised nursing subjects. The ideal was a learning process which was motivated by enjoyment and free participation and thus where not only reason but also the heart was involved.From Testrup, Birkelund traces the thread back to Gr. and aims thus to demonstrate that it was Gr’s pedagogic ideas - and herein Gr’s concept of lifeenlightenment (livsoplysning)- which formed the basis of the experiment in Testrup. Birkelund hereby offers an excellent introduction to Gr’s educational ideas.With the historical-poetic as his point of departure, Birkelund leads us in the final section of the book from Gr. to Løgstrup, for he believes that Løgstrup’s ethical and aesthetic views - and herein his concept of existential enlightenment [tilværelsesoplysning] - are a further development of Gr’s philosophy of life-enlightenment. He thus sees Løgstrup as giving a contemporary currency to both Gr and the experiment at Testrup.The modernist critique which Birkelund formulates in Livs-Oplysning is carried further in the recently published anthology Eksistens og livsfilosofi [Existence and Life-philosophy], edited by Birkelund. Here a series of prominent Danish and Swedish scholars present some of the most epochmaking Danish, Swedish, German and French life-philosophers. The book works within the same framework of a pre-scientific perspective upon life as Livs-Oplysning: life is more than theories about life. It is this ‘more,’ this existential supervention, which life-philosophy endeavours to embrace, and it is the relevance of this life-perspective to the whole field of educational, social and health concerns that this book desires to assert. Among the lifephilosophers selected for presentation, Løgstrup and Gr. again appear along with, to name only a few, Jakob Knudsen, Hans Lipps, Søren Kierkegaard, Martin Buber and Hannah Arendt.Again, we are dealing with an important book which offers inspiring reading: but the book has its weak points. The foreword proposes that lifephilosophy rests upon a revolt against the overdominance of rationalism: but is this an adequate characterisation of life-philosophy? is it sufficiently discriminating to call both Løgstrup and Kierkegaard life-philosophers? Løgstrup himself (Opgør med Kierkegaard [Confrontation with Kierkegaard^) has argued that life-philosophy in many ways entails a confrontation with (Kierkegaard’s) existential philosophy. While both life-philosophy and existential philosophy represent a showdown with the rationalism cultivated by Enlightenment philosophers, they go about it in diverse ways.

Abstract. The knowledge of historical ozone in the upper troposphere/lower stratosphere (UT/LS) region is mostly confined to regular measurements from a number of ozonesonde stations. We present ozone measurements of the Global Atmospheric Sampling Program (GASP) performed from four commercial and one research aircraft during 1975 to 1979. Using GASP data, a UT/LS ozone climatology of 1975–1979 was built. Seasonality and concentrations of GASP UT ozone in the middle, subtropical and tropical regions of the northern hemisphere (NH) are generally in agreement with other published observations, derived from ozonesondes or aircraft campaigns. In regions where both GASP (1970s) and MOZAIC (1990s) data are available, similar ozone concentrations are found and seasonal cycles agree well confirming the reliability of GASP ozone. GASP provides unique large-scale climatological information on UT/LS ozone above the NH Pacific region. Agreement is found with observations from individual ozonesonde sites and aircraft campaigns carried out over this region. Tropical UT ozone is seen to be lower near the dateline than further east, presumably related to uplift of ozone poor air within convection. Over the west coast of the United States, summer UT ozone is higher than over the adjacent Pacific, probably caused by air pollution over southern California in the 1970s. GASP offers an unprecedented opportunity to link to European, Canadian and U.S. American ozonesonde observations of the 1970s. For the quantitative comparison, an altitude offset was applied to the sonde data to account for the slow response time of the sensors. In the LS, the European and Canadian Brewer-Mast (BM) sensors then agree to ±10% with the GASP instruments in all seasons. In the UT, the European BM sondes record similar to slightly less average ozone than GASP, however, with large variability overlaid. Over the eastern United States, systematic positive deviations of the Wallops Island ECC sondes from GASP of +20% are found. The comparisons over Europe and the eastern United States corroborate earlier findings that the early ECC sensors may have measured 10 to 25% more ozone than the BM sensors. Our results further indicate that applying the correction factor to the 1970s BM ozonesondes is necessary to yield reliable ozone mixing ratios in the UT/LS.

This article investigates the scope of ideology that infected poetry in the nineteen seventies; the processes of marginalization of uncomfortable poetic voices, and respectively, the mechanisms imposing propaganda and anthologizing the poetically wrapped agitation; the stabilizations and tensions along the centre-periphery axis; the role of anthologies by authors not from the capital in the process of making sense of the country (province) as one free from the political poetic category. In a synchronous plan, some anthological specimens were issued over a short period of time, e.g. Poetic Anthology about the Silent Feat (1974), The High Wave (1974), Sprays (1975) and Poppies (1977). The first anthology is dedicated to the law enforcement agencies and to the state security. The second is an oriented and ambitious paragon of socialist realism poetry. The third anthology has been conceived of as a forum for the authors who were selected exclusively from among the members of the Union of Bulgarian writers. The fourth volume is a seemingly unpretentious collection that defines itself as an anthology. The compilation process, however, took pains far greater than expected – it was a three-year long odyssey from the moment the anthology of national/home poetry was included in the publishing plan for 1975 to the admission of an unnamed title in the publishing plan for 1977, as well as the resulting marginalization of the Poppies anthology after its publication.

After the text-based editorial approach of the 17th and 18th centuries, from the end of the 19th century, and even more from the middle of the nineteen-seventies, more and more scholars turned towards the study of stage directions. They started to discover their origins, their meanings, and their impact on the understanding of Shakespeare's plays. These researches led to the fact that Shakespeare criticism could no longer remain within the limited realms of literature, but it had to involve other disciplines such as cultural studies and theatre history in its researches too. The traditions of Elizabethan theatre and the relationship between theatre and literature came into the focus of research. This paper gives a comparative analysis of stage directions in one particular scene, the ballroom-scene (I.iv) of Romeo and Juliet, as they are presented in six prominent 20th-century editions. This study is to prove that nearly all the problems an editor has to face are theatrical in nature and therefore it is necessary to re-establish the relation between page and stage and to make performance-based editions that are useful to theatrical personnel as well as academics.
