Loddeundersøkelser i Barentshavet høsten 1978

From 14 September to 11 October investigations on the Barents Sea capelin stock were carried out, with aim on the geographical distribution of the stock, its structure and assessment of the abundance. Compared to the situation in 1977 the hydrographic situation in the western part of the Barents Sea was much the same. In the eastern part, the temperature was lower than in 1977, especially at the surface. This difference increased with increasing longitudes, and in large areas it was about 2°C. The geographical distribution of capelin was much the same as in 1977, except for the northwestern area where little or none capelin was recorded. The main concentrations were located around the two positions: 77°20'N-34°00'E and 77°40'N-41°00'E. The 1977 yearclass was found to be extremely poor. The size of the spawning stock was assessed to be 1.7 mill. tonnes. The 1975- and 1974-yearclasses will dominate the spawning stock in 1979

Self-directed learning : A core concept in adult education

In adult education, the concept of self-directed learning has great importance. This term arose in the field of adult education in the 1970s and is still a widely used term in the field. Annual symposiums have been held by the International Society for Self-Directed Learning since 1986, dedicated to the promotion of self-directed learning. The society also publishes an international journal of self-directed learning. A term of more recent origin is self-regulation, used by some authors sometimes interchangeably with self-direction. This review article focuses on the term self-directed learning, which is the term most frequently used in adult education. Many consider the tendency for self-direction to be a fundamental difference between children and adults in a learning situation. This article deals with some factors that affect the understanding of self-directed learning. At the beginning is given a short case story and an account for different perceptions of self-directed learning. This is followed by a clarification of different aspects of self-directed learning, such as why it is advisable, what affects the tendency to self-directed learning, and if self-direction is essentially innate or learned. The situational aspect is dealt with separately as a relatively self-contained aspect of self-directed learning. The presentation is based on a literature study.publishedVersio

Statistical Methods for Calculating the Risk of Collision Between Petroleum Wells

In this thesis we explore several statistical methods for addressing the risk of collision between two petroleum wells. Such a collision is a potentially dangerous but rare event that can occur in situations with directional drilling. In order to extend the usual approach of only considering the two closest points in the two wells in the collision risk calculations, we obtain a joint statistical distribution for the position coordinates of all the survey points in two neighboring wells.The common practice in the petroleum industry today is to use the two closest points in a hypothesis test, in order to make a conclusion on whether we should drill as planned based on the collision risk. We suggest a more accurate version of the hypothesis test, which turns out to be more conservative than the original test.As an alternative measure of the collision risk, we estimate the probability of collision. This is done in two different ways, namely by considering only the two closest points and by considering the whole wells. In the latter case, we use the joint distribution for all the survey points. For some well pair cases, the collision probability is much larger when we consider all the survey points in two wells, than when we only consider the two single closest points.We estimate the probability values by using Monte Carlo simulation methods. Since a well collision is considered to be a rare event, we introduce two methods in order to increase the accuracy in the situations where the original Monte Carlo method need an inconveniently large number of samples. These methods give accurate results even when the collision probability is very small

Growth of 0-group fish in relation to temperature conditions in the Barents Sea during the period 1965- 1989

Since 1965 the International 0-group fish survey has been carried out in the Barents Sea during late August and early September. The main purpose is to determine the year-class strength of some commercial fish species at an early stage in their life history. The present contribution is a preliminary study on the growth of the 0-group during the first half year after spawning. Comparisons of lengths of cod, haddock, herring and capelin strongly indicate similar variations from year to year. Since these species inhabit partly the same water masses the first six months, it is likely that the variation in growth depends on some common factors. One of these may be the temperature of the environment. The results so far indicate a relationship between the growth of larvae and temperature

Unravelling the Norwegian meat reduction controversy: navigating contested sustainabilities and the role of meat

Controversy surrounds research reports that promote reduced meat consumption in Norway. By studying these controversies in the media, we ask why meat reduction is polarised seemingly between environmental and agricultural, urban and rural voices. We show how a ‘conventional’ definition of meat reduction in a self-regulating market tends to disconnect consumption habits from agricultural policies. The result is a paradox: Norwegians are urged to eat less meat, but farmers must produce more to stay afloat. In this conventional frame, meat reduction is seen by rural and farmer voices as a further exaggeration of agricultural decline, depopulation and centralisation. To unravel this controversy, we contrast this with a critical ‘post-productivist’ view of conventional agriculture and volume-centred farm subsidies since the 1950s. We show how a different, more interactive understanding of consumption as interrelated with Norwegian food policies, production and distribution emerges, highlighting a path through the controversy. By reimagining a change from subsidies for production volume to production methods, climate, health, environmental and rural issues are brought into conversation with each other. While largely remaining a marginal voice in a heavily polarised debate, we show how alternative notions of meat reduction can help us move past meat reduction controversies. The article stresses that the two concepts of meat reduction are characterised by distinct notions of consumption, suggesting that the popular understanding of what consumption is can be a barrier to, or a part of, a meat-reduced future.acceptedVersio
