The northern Norwegian killer whale (Orcinus orca) is an important predator but little is known about its population dynamics, particular in response to changes in its main prey, the highly dynamic Norwegian spring spawning (NSS) herring (Clupea harengus). The main aims of this thesis were to estimate killer whale population parameters, to explore the future viability of the population, and to explore the response of this predator to changes in distribution and abundance of its main prey over the last 25 years. Population size was estimated as ~ 700 individuals, taking heterogeneity of capture probabilities into account and correcting for unmarked animals. Apparent survival rates of 0.974 (SE = 0.006) for adult males and 0.984 (SE = 0.006) for adult females were estimated accounting for temporary emigration, transience and trap-dependency. Temporary emigration was greater for males than females. Calving intervals ranged from 3 to 14 years (mean = 5.06); equivalent to 0.197 calves per mature female per year. Future viability of the killer whale population was evaluated under various plausible scenarios. The baseline scenario using the best available information predicted a viable population and indicated that the population may be increasing size. Analysis of data on naval sonar activity, killer whale sightings and herring abundance showed that naval sonar activity appeared to have a negative effect on killer whale presence during a period of low prey availability. A time lag of four years was found between the first sign of NSS herring changing its distribution and reduced killer whale presence inside the fjord system. Analysis of energy budgets showed that killer whales spent more time travelling/foraging in 2005/06 than the 1990s. The fjord system was inferred to be a preferred habitat for killer whales when there was a higher density of NSS herring in this area compared to offshore area.

Thesis (MA)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: African affairs have traditionally not occupied a central place in Norway’s official foreign policy, and relations with countries in West Africa have been limited. However, in recent years, resource-rich countries such as Angola – Africa’s largest oil producer – have become the focus of Norwegian strategic interests. Private and public investments are increasing rapidly, paralleling a larger focus on aid. Today, Angola is a core country within Norway’s most prominent petroleum-related assistant programme, Oil for Development (OfD). This thesis will aim to contribute, by means of a critical political economy analysis, to a better understanding of Norway’s role in Angola through OfD. Specifically, this study aims to question who and what structures Norway really is aiding in Angola. Such an objective will be achieved by firstly using critical theory to demonstrate Norway’s role as a traditional middle power – through which Norway seeks to export an altruistic perception of a ‘do-good- image’ – is underpinned by a deeper national self-interest. Secondly, the thesis questions the theoretical foundation of OfD, and, thirdly, it attempts to identify whom the OfD programme is aiding. Ultimately, the thesis questions whether Norway is promoting sustainable development in Angola, or whether, instead, it is contributing to maintaining a status quo, from which Norway as a middle power continues to benefit. The study illustrates that Norway, as a middle power, has neither the capacity nor the national self-interest to achieve fundamental change in Angola. Norway’s commitment to the good governance agenda, and the belief in solutions offered by the resource curse thesis, is tackling the symptoms of Angola’s underdevelopment, rather than its root causes. OfD adopts a state-centric approach, which accepts the political economy structures in Angola, and gives limited attention to global structures and civil society. The thesis offers an alternative analysis, which illustrates how OfD is masking a neo-liberal development approach by incorporating Norwegian business interests and development goals in the same programme. / AFRIKAANSE OPSOMMING: Afrika sake het tradisioneel nie 'n sentrale plek in Noorweë se amptelike buitelandse beleid beklee nie, en verhoudings met die westelike deel van die Afrika-kontinent is beperk. Tydens die afgelope jare het olie-ryk lande, soos Angola, egter die fokus van Noorweegse strategiese belange geword. Angola is vandag 'n kern land binne Noorweë se mees prominente petroleum-verwante hulpverleningsprogram, Oil for Development (OfD). Hierdie tesis het ten doel om, deur middel van 'n kritiese politieke ekonomie ontleding, by te dra tot ’n beter begrip van Noorweë se rol in Angola deur die OfD. Spesifiek bevraagteken hierdie studie aan wie en watter strukture in Angola Noorweë hulp verleen. Dit sal gedoen word deur eerstens gebruik te maak van kritiese teorie om te demonstreer dat Noorweë se rol as 'n tradisionele middelmoondheid – waardeur Noorweë poog om 'n altruïstiese persepsie van die staat uit te dra – onderskryf word deur 'n dieper nasionale selfbelang. Tweedens sal hierdie studie die teoretiese begronding van OfD bevraagteken, en derdens poog om te identifiseer wie deur die OfD program ondersteun word. Laastens sal die tesis bevraagteken of Noorweë volhoubare ontwikkeling in Angola bevorder, en eerder bydra tot die instandhouding van die status quo, waaruit Noorweë as 'n middelmoondheid voordeel trek. Die studie sal illustreer dat Noorweë, as ‘n middelmoondheid, nie die kapasiteit of die nasionale selfbelang het om fundamentele verandering in Angola te weeg te bring nie. Norweë se ondersteuning van die ‘good governance’ agenda, en oplossings wat deur die sogenaamde ‘hulpbronvloek’ tesis aangebied word, spreek die simptome van Angola se onder-ontwikkeldheid aan, eerder as die kernoorsake. OfD funksioneer op grond van ‘n staat-sentriese benadering, wat die politieke ekonomiese strukture in Angola aanvaar, en beperkte aandag aan globale strukture en die burgerlike samelewing gee. Hierdie tesis bied ‘n alternatiewe analise, wat wys hoe OfD eintlik ‘n neoliberale ontwikkelingsbenadering volg wat Noorweegse besigheids- en ontwikkelingsdoelwitte in dieselfde program inkorporeer.

Personnel managers in different firms, industries and countries do not hold the same preferences for job applicant attributes. This research was aimed at understanding the cause of some of these differences. Survey questionnaires were sent to personnel managers in Norway (N = 195) and Quebec (N = 172). The personnel managers were asked to rate: (1) aspects related to their firms' organizational characteristics (business environment, strategy, and structure), and (2) the importance of different personality traits for applicants to managerial and professional positions. Consistent with earlier research (Rynes & Gerhart, 1990) the results indicate that preferences for different applicant attributes represent shared perceptions due to common organizational membership. These preferences are to some degree related to company strategy, organizational structure and national culture. In general, it was found that personnel managers currently seek candidates who can adapt to change and generate new ideas. The results are discussed in light of theories from industrial/organizational and cross-cultural psychology, and suggestions for further research are offered.

High Purity Quartz (HPQ; quartz containing less than 50 ppm trace elements) is of increasing economic significance due to its use in certain high-tech components (computer chip/semiconductor manufacture) and in green technologies (silicon wafer production). Current HPQ deposits (hydrothermal veins/leuco-granites/alaskites) are rare and volumetrically small. Unless significant new deposits are found, increasing demand will raise its prices, elevating the strategic nature of this limited commodity. The large volumes and simple mineralogy of pegmatites and the high chemical purity of their constituents make them an attractive target for HPQ. PhD studies are being carried out on quartz from the Evje-Iveland pegmatite field of the Bamble-Evje pegmatite cluster, southern Norway. The area was targeted due to its well constrained geological setting and previously identified potential for HPQ. The aim of the investigation is to develop exploration tools for HPQ by determining the genetic history of the pegmatites and mode of HPQ formation. The study is focussing on 7 pegmatites and their country rocks. Each shows typical pegmatite zonation, with quartz/feldspar intergrowths at the margins, a massive quartz core and a variety of accessory (including REE-bearing) phases. The proximal Høvringsvatnet granite was previously suggested to have supplied late-stage, highly fractionated melts to form the pegmatites. However, from their trace element systematics (no relationship was observed between trace element content and degree of fractionation in each pegmatite body), and a difference in U/Pb age of approximately 70 Ma, the pegmatites cannot be related to the granites. From field evidence (corroborated by geochemical modelling) the pegmatites formed by ‘in situ’ anatexis of country rocks; some locally, some from distal sources. Some pegmatites contain brecciated feldspar and replacement quartz. From LA-ICP-MS analyses, hydrothermal quartz, compared with magmatic quartz, typically contains lower quantities of trace elements. Hydrothermal material shows relatively elevated levels of Al and Li, low Ge and a complete absence of Ti, indicating relatively low temperature hydrothermal formation. Different quartz domains (from SEM-CL imaging) show distinct δ18O values; late stage low trace element zones show values consistent with meteorically derived fluids. In situ LA-ICP-MS studies will provide further information about the characteristics of the fluids which have replaced/refined magmatic quartz to form HPQ. This beneficiation process is a potential mechanism for the generation of economically significant HPQ deposits.

In this study four different aspects of primary successions on glacier forelands in South-Central Norway are investigated. First, general vegetation and environment trends, which have been observed by other scientists, were studied on two forelands. It is shown that the two selected forelands (one low- and one high-altitude foreland, Nigardsbreen and Storbreen, respectively) differ in the speed of vegetation cover change and in the overall species richness developed over the last 250 years since deglaciation. This is attributed to differences in the severity of the environment between the two forelands. Some support for an early peak in the number of species was found for the Nigardsbreen foreland, whereas the Storbreen foreland shows no significant trend in the development of species richness. Life-forms and soil-depth change on both forelands in the predicted manner. A novel approach for the use of Ellenberg indicator values for the estimation of pH-values from the existent vegetation shows highly significant correlations between predicted pH values and trends measured for similar terrain ages from a study by Messer (1988). Investigation at two different scales indicated that small-scale disturbances (< 100 m) may influence the mosaic of the environment, which affects the results of the chronosequence approach. By using a strict geometrical sampling design more variable conditions entered the analyses than with the stratified random sampling schemes adopted by others, such as Matthews (1979b). Some loss in the power of analysing the data occurred, but the results are still consistent with hypotheses about primary succession on glacier forelands. Second, new aspects of the temporal development and successional change of plant communities were investigated on the same two forelands. There is some evidence of succession from a pioneer community to the local climax community of the surrounding area for both forelands. There is also support for the correlation of timedependent environmental variables with the successional development of plant communities. A new application of Ellenberg indicator values in ordinations was assessed for its value in estimating average environmental conditions derived from the vegetation. As with the previous analyses, investigation of community development at two different scales supported the importance of sampling scale on the analysis of succession data. Third, spatially explicit analyses of distribution patterns of dominant woody species was developed as a means to investigate processes and formulate hypotheses about primary succession on glacier forelands. The data for this part of the study was collected on five glacier forelands, three low-altitude (Nigardsbreen, Austerdalsbreen and Bødalsbreen) and two high-altitude (Storbreen and Høgvaglbreen). Pattern descriptors including perimeter/area index, autocorrelation measures and fractal dimensions, support the hypothesis of differential colonisation of wind and animaldispersed species. Even more convincing is the result that low- and high-altitude forelands show significant differences in the patterns exhibited by wind and animals dispersed species. This result is thought to be related to the differences in environmental severity affecting the establishment of colonising species. Finally, logit modelling of the distributions of dominant woody species provides insights into the sampling effort needed to gather enough data for meaningful analyses. It also leads to the identification of important factors influencing the distribution of those species.

This thesis explores the strength of the two major theories of punishment, consequentialism and retributivism. It also explores the two most critiqued systems of punishment in the world: The U.S and Norway. By presenting the idea that retributivism is the only plausible theory that can morally justify the U.S. penal practises, I argue against the theory by incorporating various objections delivered by Antony Duff, Michael Zimmerman, and Jeffrie Murphy. I then explore the question of what could possibly ground the Norwegian justice system, for the answer to this is crucial, if we hope to demand prison reform and tailor our systems to resemble the Norwegian ideal. To answer this question, I present a theory that incorporates the ‘capabilities approach’ as developed by Martha Nussbaum and Amartya Sen, arguing that the Norwegian prison system is grounded in a hybrid theory of consequentialism that aims to enhance our human rights.
