Linking ecology and management of water quality : the distribution and growth of phytoplankton in coastal lakes of British Columbia

Davies, John-Mark. 10 April 2008 (has links)
Processes regulating the growth and successional pattern of phytoplankton and the production of odour compounds in lakes of coastal and interior British Columbia were examined. An emphasis was placed on the role of nutrients, the role of size in determining nutrient deficiency, and the importance of winter for understanding the functioning of coastal lakes. Although the study lakes were all phosphorus limited (TN:TP molar ratio >22), plankton, especially the greater than 3 pm size fraction, were often nitrogen deficient. This demonstrates the importance of nitrogen as a growth regulating nutrient for larger plankton in these lakes. Seasonal patterns of productivity varied among lakes, and Maxwell Lake was found to reach maximal photosynthetic rates in February. Lakes without a dominant seasonal physical influence (e.g. ice-cover) and those subject to short-scale stochastic events that play dominant roles may not have their "successional clock" set. This can lead to an apparent chaotic seasonal pattern of species distribution. In coastal lakes the lack of strong seasonal patterns is more likely to occur in lakes with lower nutrients (e.g. <10 pg TP-L-') than in lakes with relatively high nutrients (>I5 pg TP.L-') because of the seasonal cycling of nutrients within eutrophic lakes. The origin of odours in drinking water was examined from nineteen lakes and reservoirs to determine links between limnological variables and classification and intensity of odour. Total phosphorus (TP) was the best single predictor of odour intensity. Vegetation and grassy odours were more prevalent in lakes with TP less than 13 pgL-', while earthy odours were common at higher TP. Drinking water quality issues were reviewed and the relationship between policy, management and science was examined. This work stresses the importance of sound science to ensure the legality, legitimacy, efficiency and effectiveness of implementing water quality policies and for establishing best management practices.

The Natural Embroidery of Thomas Southerne's Oroonoko

Hancock, Sarah Rose 17 May 2016 (has links)
In this thesis, I plan to investigate the role of the landscape in Thomas Southerne's play Oroonoko. Most scholarship on Oroonoko focuses on the relationship between Southerthne's play and Aphra Behn's novella of the same name. In particular, the scholarly conversation has focused on the way that Southerne white-washed Aphra Behn's character Imoininda. While this distinction is notable, my research, instead, will focus on the way these bodies—both white and black, colonizer and colonized—are framed by 18th century gardening rhetoric. This rhetoric provided naturally conceived tools for nurturing these bodies. I plan to argue that the language of the natural world used in the play demonstrates the role of landscape in the formation of British national identity. / McAnulty College and Graduate School of Liberal Arts; / English / MA; / Thesis;

Telling fashionable tales : the form and function of the non-fiction British fashion film

Stephenson-Thompson, Jo January 2017 (has links)
This thesis examines the promotion of the British fashion industry in the underexplored genre of non-fiction British fashion film. Whilst critical attention has been paid to the role of fashion within fiction film, and costume within historical drama, the significance of fashion in non-fiction, state-sponsored British film has passed largely without exploration. The threshold of fact and fiction is the site of investigation in this analysis of film and media materials, that draw on fairy tale narratives of transformation to produce fashion as the 'integration of the two worlds of reality and imagination' (Bettelheim, 1975). The main focus of my analysis is a body of texts ranging from the forties to the present day. The corpus of study consists of films produced by British Pathé and the Central Office of Information (COI), film, televisual, and DVD outputs of royal weddings, and the BBC's live television broadcast of the 2012 Olympic Games. Fashion has a reputation for facilitating change and performing makeovers, and the texts studied here present three levels of transformation, powered by the magical fiction of fairy tales, the transformative potential of capitalism, and the renewing capabilities of the fashion industry. These texts demonstrate the way fashion stories are used to negotiate key historical junctures in British identity, finding in the structure of the fairy tale a way to articulate an economy of renewal that can be harnessed to a national, ideological state agenda aimed at women. This thesis argues that national events are commandeered as platforms for officially sponsored tales of Britain's heritage, which testify to the importance of fashion to the British economy and its role in political strategy.

Seismotectonics of the explorer region and of the Blanco Transform Fault Zone

Braunmiller, Jochen 23 October 1998 (has links)
In this thesis, we present the first detailed, long-term seismotectonic studies of oceanic ridge-transform systems. The proximity of the Juan de Fuca plate to a network of broadband seismic stations in western North America provides a unique synergy of interesting tectonic targets, high seismicity, and recording capabilities. Our main tools are earthquake source parameters, determined by robust waveform modeling techniques, and precise earthquake locations, determined by joint epicenter relocation. Regional broadband data are used to invert for the source moment tensors of the frequent, moderate-sized (M ≥ 4) earthquakes; this analysis began 1994. We include Harvard centroid moment-tensors available since 1976 for larger (M ≥ 5) earthquakes. Two studies comprise the main part of this thesis. In the first, we determine the current tectonics of Explorer region offshore western Canada. Earthquake slip vector azimuths along the Pacific-Explorer boundary require an independent Explorer plate. We determine its rotation pole and provide a tectonic model for the plate's history over the last 2 Ma. Plate motion changes caused distributed deformation in the plate's southeast corner and caused a small piece in the southwest corner to transfer to the Pacific plate. Capture of the plate fragment indicates that preserved fragments not necessary represent entire microplates. In the second study, we investigate seismicity and source parameters along the Blanco Transform Fault Zone (BTFZ). The deformation style-- strike slip and normal faulting-- correlates well with observed changes in BTFZ's morphology. We infer that Blanco Ridge probably consists of two fault segments, that several parallel faults are active along BTFZ's west part, and that Cascadia Depression possibly is a short spreading center. The slip distribution along the BTFZ is highly variable, although seismicity could account for the full plate motion rate along the entire BTFZ. The final part is a short study where we locate an earthquake in the tectonically active Mendocino triple junction region offshore northern California using land and offshore data. The precise location may be useful as a master event for relocating other earthquakes. / Graduation date: 1999

Partnerships for affordable housing: an examination of the barriers faced by municipalities and the non-profit housing sector

Garnett, Lee-Ann Gail 05 1900 (has links)
The changes in housing policy during the 1990s has been profound. With federal funds for non-market housing no longer available, the Province of British Columbia has attempted to involve municipalities to a greater extent in meeting the housing needs in their communities. However, this has proved to be an immense challenge for many municipalities. Nevertheless, many have reported that they use, or in the future will use, partnerships with other organizations to obtain more affordable housing in their communities. Specifically, partnering with non-profit housing organizations is seen as one means of achieving this. The non-profit organizations, too, find building more affordable housing a challenge, and are interested in working with municipalities where possible. The intent of this research, then, is to analyze the relationships between local governments in B.C. and non-profit societies, and identify some of the barriers that each party faces. The research also examines the roles of some of the other participants in affordable housing. For municipalities, the barriers faced by them to enter housing partnerships are great. A lack of resources, the absence of staff dedicated to housing issues, the lack of staff expertise required to analyze complex housing partnerships, and a lack of commitment on the part of politicians all contribute to the difficulties in having these agreements. The non-profit housing groups also face deterrents, such as small staff sizes, few resources, in some cases, little expertise in development, or ageing board members who do not wish to build new housing. These barriers, however, are not insurmountable, and recommendations are provided to overcome them. It is important to realize that although housing partnerships can be a very effective tool, they are just one of many that municipalities use to meet the housing needs in their communities. Ultimately, housing needs will best be met by having all levels of government, the private and non-profit sectors working together towards common goals.
