This work investigated the consequences of vegetable oils spills in salt marsh sediments. The role of autochthonous bacteria in the oils degradation and degradative pathways were also studied 'in situ' and 'in vitro'. Simulated spills of sunflower and linseed oils revealed that both oils penetrated the sediments at a rate of 10-7 CM2 s-1. However, whereas 60% of the linseed oil had disappeared from the sediments after 2 months most of the sunflower oil remained after 6 months. Differences were noted in the adsorption of the oils to sediment particles and the depth at which they accumulate and these factors most likely influenced the route of the oil degradation and the sediments properties such as permeability. The contamination of the sediments with vegetable oils lead to a noticeable reduction in the abundance of plant roots and infauna. The abundance of aerobic, anaerobic and sulphate reducing bacteria in the sediments was increased by the addition of both oils, with linseed oil supporting greater bacterial density than sunflower oil. During the course of the experiment the relative abundance of oil degrading bacteria also increased. As a consequence of the increased bacterial activity, the sediments pH and Eh decreased and anoxic conditions were established, earlier in the case of linseed than that of sunflower oils. The degradation of the oils appeared to be a sequential process, initiated by the aerobic and/or anaerobic bacteria and continued by the sulphate reducing bacteria which themselves where unable to utilise the raw oils. The original composition of both oils underwent alterations mostly associated with their main fatty acid: the concentration of 18: 3(o3 and 18: 2o)6 in linseed and sunflower oil, respectively, decreased whereas that of the remaining fatty acids increased. As a result of the bacterial degradation of the vegetable oils 'new' fatty acids were detected and their identification was attempted using GC-MS analysis of their picolinyl and methyl esters. Various degradative pathways of linseed and sunflower oils involving the formation of the 'new' fatty acids are suggested with isomerisation, hydrogenation and P-oxidation as the primary routes for the degradation.

This study was a replication of Fitzpatrick and Rubin's study of response strategies used in crisis communication. It differed though, in the type of crisis analyzed. While Fitzpatrick and Rubin studied cases of sexual harassment, this study examined oil spills of two supertanker groundings. Both the Exxon Valdez and the Sea Empress groundings, and especially Acomarit and Exxon, the companies responsible were examined by using content analysis. Units of analysis were statements by each company's spokesperson covered in either four American or four Norwegian newspapers. These statements were then categorized as one of four response strategies defined by Fitzpatrick and Rubin which were as follows: (1) The traditional public relations strategy, (2) The traditional legal strategy, (3) Mixed strategy, and, (4) Diversionary strategy.On behalf of these response strategies the study stated two hypotheses:H1: The spokespersons of Acomarit used the traditional public relations strategy significantly more than the traditional legal strategy, as defined by Fitzpatrick and Rubin, in Norwegian newspapers.The hypothesis was accepted.H2: The spokespersons of Exxon used the traditional legal strategy significantly more than the traditional public relations strategy, as defined by Fitzpatrick and Rubin, in American newspapers.The hypothesis was partially accepted.The study used an American and a Norwegian coder to secure reliability. Holsti's coder reliability test yielded eighty percent for the American statements, and seventy percent for the Norwegian statements.The study also indicated that the traditional public relations strategy was the most used response strategy. This was different to what Fitzpatrick and Rubin found in their study. They found the traditional legal strategy was used the most in cases of sexual harassment.However, both Exxon and Acomarit used the traditional public relations strategy more than the traditional legal strategy, but differed significantly in their use of mixed strategy and diversionary strategy. Exxon was found to have used the diversionary strategy significantly more than Acomarit. The researcher indicated that this may have been one of the contributing factors which lead to Exxon's public relations nightmare. In addition, Exxon was found to have used more spokespeople than Acomarit, which in turn may have made it difficult to centralize the information flow. / Department of Journalism

One of the most pressing and polarizing issues in Western Canada today, and for many First Nations groups in particular, is the oil sands of Alberta. My thesis is entitled Energy Uncertainty: The Effects of Oil on the Woodland Cree First Nation. My research is focused on understanding how long-term energy extraction affects the past, present, and futures of the members the Woodland Cree First Nation (WCFN) who are demanding an active role in the planning and consultation processes that affect their lives and their traditional lands. I have found that the energy consultation process is not working for the interests of the WCFN and the effects of oil extraction in this community are examples of how and why it is not working. During the summer of 2013 I spent nine weeks in the WCFN community and used three methods of research: participant observation, interviews, and literature analysis. I completed 22 interviews during my field work research, and made use of nine transcribed interviews with WCFN elders collected in 1995 by Rhonda Laboucan. I used a grounded approach to the content and thematic analysis of my interview and field note data. My thesis is guided by a political ecological approach because this framework challenged me to look at this subject from many angles and perspectives. This approach has kept my research from being narrowly focused on abstracted or stereotypical aspects of the energy extraction process which I cannot understand without attention to its social, political, environmental, and spatial aspects. The body of my thesis includes three chapters which explore: • The practical realities of energy consultation and its relation to Treaty Eight and Traditional Knowledge. • The complex relationship between temporality, fatalism, and the effects of the oil industry on the people, land, and animals of the WCFN. • A detailed ethnographic description of the events and processes that followed a contaminated water spill on the WCFN traditional land. My key findings include: consultation is not working for the interests of the WCFN; oil is impacting the animals, environment, and WCFN community; oil-related spills are affecting (but not being dealt with in a way that respects) WCFN people or land; and there are problems with collection, interpretation, dissemination, and even access to energy extraction and consultation information. My research helps to fill the gaps in our understanding of the complex effects of long-term energy extraction on small communities, in particular the impacts of oil and oil sands development in a small First Nations community context.
