Stories about the oil and gas industry are made for drama; these are tales of unimaginable wealth, unimaginable power, and oftentimes, unimaginable deeds. But what should we make of an oil and gas narrative without a blood feud or villain? This is the story of the Norway Model, a unique system of natural resource management responsible for this country’s transformation since 1969 when massive oil reserves were discovered on the North Sea continental shelf. After centuries of foreign occupation, the Norwegian government has built a thriving petroleum sector to fund its social welfare system beyond even the highest expectations; somehow, this nation of five million people grew from a poor maritime society to a global leader in environmentally conscious energy production with the largest sovereign wealth fund in the world. Despite these results, this oil economy faces new challenges in the coming years; as North Sea production declines, Norway increasingly looks north for fossil fuels in the Arctic and how these resources are discovered, produced, and regulated will require new innovations to ensure the sustainability of this welfare state. Thus, the next chapter of the Norwegian success story remains to be written and this dissertation explores how narratives about the past, present, and future of the Norway Model will shape the course of natural resource management policies. In presenting the case of Norway’s success from a narrative perspective, this research breaks new ground in both applied and theoretical territories. As perhaps the most successful system of its kind in the world, scholars and policy makers alike have much to learn from studying this model. But when it comes to understanding the dynamic connections between energy management, international policy, and global warming, positivistic models for prediction and causality have fallen short (Smil, 2005). In contrast, narrative can communicate nuanced meanings in complex systems of organization. Therefore, this research explores the connections between narrative and complexity, as well as the communicative applications of narrative for understanding and organizational decision-making. Overall, conceptualizing this model’s evolution as a narrative offers tangible entry points for understanding how one country’s story can change the world. / text

This thesis uses data collected over three summers in 2010, 2011 and 2012 at the Isle of May National Nature Reserve, Scotland to examine top predator presence and behaviour in a moderately fast tidal stream site. Fieldwork consisted of an intensive land based observation survey of seabirds at sea, acoustic monitoring of small cetaceans and the deployment of a suite of oceanographical tools to simultaneously collect data on a fine temporal scale over a study area of ~1.5km2. The aim of the study was to examine the potential effects of marine renewable energy developments on top predator behaviour in a tidal stream site by addressing some of the key data gaps such as habitat use in tidal stream areas, dive behaviour and collision and disturbance risk assessment. Acoustic detections of harbour porpoises were investigated as a function of physical environmental variables. Strong links between porpoise presence and increased thermal stratification and chlorophyll levels were detected along with a very strong diurnal pattern with increased detections at night. There was no relationship with tidal state. The habitat use of five species of breeding birds at sea adjacent to breeding cliffs was examined to gauge what environmental factors drive habitat use at these sites. Counts of foraging kittiwakes were examined in relation to environmental variables and while strong temporal trends emerged there was no link with oceanographic features. The study site was predominately used for loafing (non foraging behaviour) and so species specific temporal variation in loafing behaviour was analysed. Strong seasonal and diurnal trends in loafing emerged for all species which could be linked to differences in their breeding phenology. These results can be used in assessing and mitigating disturbance to these birds from marine renewables developments. Age specific variation in dive behaviour in the European shag was examined to determine whether newly fledged juveniles were at a greater risk of collision with tidal turbines than adults. Juveniles initially demonstrated a shorter dive duration than adults but after 4-6 weeks their dive duration had significantly increased. However age specific difference in dive behaviour in relation to water depth iii remained unchanged over time with juveniles showing no relationship between dive duration and water depth while adults increased dive duration in deeper water. The implications of this result for assessing age specific collision risk for this species is discussed. Results from this study were used to populate a framework for assessing collision and disturbance risk to seabirds in the near shore area adjacent to the breeding colony from a small scale tidal turbine development scenario. A method was developed to quantify risk by combining relative abundance data, behavioural data and published data on activity budgets for four species; guillemots, razorbills, puffins and shags. The output from this thesis has practical applications for informing the temporal and spatial scale of data collection and survey design in environmental impact assessments regarding marine renewable energy developments with emphasis on understanding the mechanistic links driving predator behaviour. Results can also be used to design appropriate mitigation procedures to prevent disturbance to loafing or foraging birds.

As input ows of secondary raw materials show high volatility and tend to behave in a chaotic way, the identification of the main drivers of the dynamic behavior of returns plays a crucial role. Based on a stylized productionrecycling system consisting of a set of nonlinear difference equations, we explicitly derive parameter constellations where the system will or will not converge to its equilibrium. Using a constant elasticity of substitution production function, the model is then extended to enable coverage of real world situations. Using waste paper as a reference raw material, we empirically estimate the parameters of the system. By using these regression results, we are able to show that the equilibrium solution is a Lyapunov unstable saddle point. This implies that the system is sensitive on initial conditions that will hence impede the predictability of product returns. Small variations of production input proportions could however stabilize the whole system. (authors' abstract)
