The costs and returns of salmon farming in British Columbia

Lee, Bradley Trenton January 1988 (has links)
Data were collected from participating grow-out salmon farmers, processors, and the B.C. Salmon Farmers' Association, through interviews, and utilized to define a base farm. A microcomputer based spreadsheet model was constructed to capture the important biological and economic variables. The model details the operating costs and returns of a farm for five years, and assumes operating costs are consistent with the fifth year to provide cash flows for a total of 20 years. The financial analysis includes an examination of the net present values, the net farm income, and the internal rate of return. Results indicate that the base farm is a viable investment at a 6.9% discount rate. A sensitivity analysis is utilized to determine the critical variables in the operation of a grow-out salmon farm. The most sensitive variable turned out to be the growth rate of salmon. The base farm was found to be vulnerable to economic variables such as the product price, and the feed price. Other important biological variables are the feed conversion ratio and the mortality rate, both of which have a significant effect on the viability of the base farm. / Land and Food Systems, Faculty of / Graduate

Patterns of adjustment of international students to the University of British Columbia

Farrokh, Kaveh January 1988 (has links)
This study has been an attempt to investigate the process of cross-cultural adjustment of a group of 13 international students studying at the University of British Columbia. The "u-curve" theory of adjustment was tested. It was hypothesized that foreign students would have individual patterns of cross-cultural adjustment. General self-concept, academic self-concept, attitude towards Canadians and attitude towards Canadian culture were used as indices of cross-cultural adjustment. The self-concept dimensions were defined by Ishiyama's self-validation theory (1987,1988). The relationship between all indices were explored. The adjustment patterns of groups of international students (i.e; Male/Female) were also explored. The main method of data interpretation was visual analysis, using two dimensional graphs. C-statistic tests (Tryon, 1982) were used to test the statistical significance of the curves. Three dimensional graphs were also used for data interpretation. Interviews were conducted at the end of the study. It was concluded that the u-curve theory of cross-cultural adjustment was not supported across all. subjects. General and academic self-concepts were found to be highly related. Academic performance was found to have a strong influence upon academic self-concept. No causal relationship was discovered between attitudes about Canadians and Canadian culture. Finally, female western foreign students were found to have the most succussfull adjustment. This was followed in succession by non-western females, western males and finally, eastern males. / Education, Faculty of / Educational and Counselling Psychology, and Special Education (ECPS), Department of / Graduate

Macro-implementation of critical thinking in British Columbia's social studies curriculum

Ford, Carole January 1988 (has links)
This study investigated how macro—implementation occurs within the British Columbia Ministry of Education. In particular, the Social Studies Curriculum Guide. Grade One-Grade Seven (1983) and related student textbooks, teacher videotapes, evaluation reports and other implementation support materials were examined to determine how the policy "critical thinking and problem-solving skills," a key component of the curriculum, was interpreted. Interviews (N=15) with relevant Ministry coordinators, committee chairpersons and members, and authors/ editors/consultants were audiotaped and later transcribed for analysis in light of the existing macro-implementation literature. It was found that the curriculum lacked clarity, was perceived variously by different policy developers, and was interpreted in discrepant ways in implementation materials. Ministry efforts to implement "critical thinking and problem-solving skills" appear to have been thwarted by lack of initial policy clarity; inconsistent liaison within the Ministry to facilitate shared expertise, understanding, and positive rapport; as well as insufficient attention to capacity building, particularly of Ministry coordinators responsible for monitoring each phase of the policy. Capacity needs highlighted in this study included adequate working conditions for developing complex policy, knowledge of the policy and its implications, as well as understanding the process of change. Future implementation prospects, may profit from research which focusses on exemplary ministry macro-implementation plans and those factors which enhance capacity building, liaison, and policy clarity. / Education, Faculty of / Curriculum and Pedagogy (EDCP), Department of / Graduate

A reevaluation of local government associations : a case study of the Union of British Columbia Municipalities

Goldsmith-Jones, Pamela J. January 1988 (has links)
This paper concerns itself with the nature of local government associations in Canada. The small body of literature concerning local government associations which precedes this study confines itself to an evaluation of local government associations based on their performance in the intergovernmental arena. In other words, ability to lobby the provincial government is the yardstick by which local government associations have been measured in the past. As this body of literature maintains that local government associations are a type of interest group, it is appropriate to attempt to situate the behaviour of these associations within some kind of interest group framework. A review of interest group literature suggests that it is inappropriate to analyse and evaluate local government associations based on the single activity of lobbying the provincial government. Local government associations spend much of their time providing other services to their membership. As well, the provision of these services impacts their ability to lobby effectively. The interest group literature suggests that members join interest groups for a variety of reasons, only some of which are related to the pursuit of a collective good. The criticisms of Lionel Feldman and Katherine Graham in Bargaining for Cities: Municipalities and Intergovernmental Relations, An Assessment and in Peter G. Johnson's research on the Union of Nova Scotia Municipalities are based on too narrow an interpretation of the activity of local government associations. This paper discusses their criticisms that local government associations are neither legitimate nor representative, that they act solely as agents of provincial governments, and that they allow themselves to be circumscribed by more senior levels of government. A case study of the Union of British Columbia Municipalities (UBCM) provides an overview of the organizational structure of this local government association, which suggests that the UBCM is an interest group whose main activities include lobbying the provincial government and providing other services to its membership. The presentation of survey data addresses itself primarily to Feldman/Graham's and Johnson's criticisms of local government associations, and concludes that when a broader range of local government association activity is taken into account, these criticisms are largely ill-founded. / Arts, Faculty of / Political Science, Department of / Graduate

A follow-up evaluation of business education career preparation programs in Vancouver secondary schools

Good, Dianne E. January 1988 (has links)
Career Preparation programs have been offered in British Columbia since 1980. However, in that time very little formal evaluation has been conducted to determine if Career Preparation programs are achieving the stated objectives. This study, based on Business Education Career Preparation programs in Vancouver secondary schools, surveyed Career Preparation students one, two, and three years after graduation. Schools which had started Business Education Career Preparation programs in September 1982 or earlier were selected. Graduates of these schools who completed a Business Education Career Preparation program in 1984, 1985, or 1986, were surveyed to determine their employment and post-secondary education experiences, whether their post-secondary education or employment was related to their Career Preparation specialties, and their perceptions of the program. The purpose of the study was to determine the strengths and weaknesses of the Business Education Career Preparation programs offered in Vancouver Secondary Schools in order to make recommendations for program improvements. The results show that 94% of respondents held at least one job since graduating from secondary school; 77% of respondents continue their education at a post-secondary institution; 67% of post-secondary programs enrolled in by respondents were at least somewhat related to their Career Preparation specialty; and 67% of jobs held since graduating from secondary school were at least somewhat related to their Career Preparation specialty. The Career Preparation program was rated at least somewhat helpful in facilitating progress in post-secondary education by 81% of respondents; 93% of respondents rated Career Preparation at least somewhat helpful in making career choices; 91% rated it at least somewhat helpful in providing employable skills; 85% rated it at least somewhat helpful in providing job search skills; and 68% rated it at least somewhat helpful in providing employment contacts. Overall, the Business Education Career Preparation program offered in Vancouver was judged as meeting the program objectives of the provincial curriculum. Recommendations are made for the program, including: matching students more carefully to work experience placements which meet their interests, career goals and specialty; more careful monitoring of work experience sites to ensure that appropriate tasks are being assigned; offering programs which will interest both males and females; coordinating employment opportunities for graduates; improving articulation with post-secondary programs; and structuring Career Preparation programs to allow for flexibility in course requirements and work experience. / Education, Faculty of / Educational and Counselling Psychology, and Special Education (ECPS), Department of / Graduate

Dorothy Clode : community educator

Moss, Ricki Carol January 1988 (has links)
This thesis will primarily focus on the career of Dorothy Clode as an adult educator, examining her leadership and influence in professional adult education associations; her advocacy regarding provincial adult education policies; and her role in community development at Lake Cowichan and in the broader context of British Columbia, as in the Consortium on Economic Dislocation. The relationship of the role of a professional adult educator to the community development process will be examined, using Clode's career as a case study. The intention is to examine the nature of adult education practice, in terms of the daily concerns, issues and philosophy of a woman whose 18 year career spanned three dynamic decades in the recent history of adult education. / Education, Faculty of / Educational Studies (EDST), Department of / Graduate

A critical guide to sources for the study of the history of the family in British Columbia, 1849-1918

Burrows, James Kenneth January 1989 (has links)
Access to archival holdings is one of the fundamental problems faced by archivists. The difficulties in providing access to the wide variety of subjects contained with even one archives is further complicated by the changing fields of research which require the use of archives. Neither provenance based or subject indexing access systems have been able to cope with these changing needs. The creation of thematic guides has been an attempt to offer more flexible subject access to collections since each guide deals with a separate topic. Despite their value in providing access to current themes, the thematic guide has been simply a listing of collections and does not offer any analysis of how various forms of records, their availability and their uses relate to the subject. The creation of such a critical guide forms the bulk of the paper. To investigate the effectiveness of this type of guide, records which relate to the study of the history of the family in British Columbia were identified. This particular subject area was chosen because of its relative newness and since many of the records applicable to its study are not easily found. The holdings of the British Columbia Archives and Records Service and the City of Vancouver Archives provided the relevant materials for the study. The records chosen as useful to the study of the family were listed and many collections were examined closely. From this review of holdings, an analysis of records types and their value to the study of the family in British Columbia was developed. Standard appraisal and descriptive techniques were employed for the analysis. In addition, a study of past research uses was done to provide a better understanding of how the records could be employed. It was found that a critical guide could be produced using modifications of standard formats, such as the basic form for inventories suggested by the Society of American Archivists. In addition, appraisal criteria were applied to the categories of documents in order to assess their value. Using these standardized techniques means that an analysis of record types will be better understood by others. The critical guide offers a vehicle for archivists to provide researchers with more information about the records in a less haphazard fashion. / Arts, Faculty of / Library, Archival and Information Studies (SLAIS), School of / Graduate

The distribution and behaviour of gold in soils in the vicinity of gold mineralization, Nickel Plate mine, southern British Columbia

Sibbick, Steven John Norman January 1990 (has links)
Sampling of soils and till are conventional methods of gold exploration in glaciated regions. However, the exact nature of the residence sites and behaviour of gold within soil and till are poorly known. A gold dispersion train extending from the Nickel Plate mine, Hedley, southwest British Columbia, was investigated in order to determine the distribution and behaviour of gold within soils developed from till. Three hundred and twelve soil, till and humus samples (representing LFH, A, B and C horizons) were collected from fifty-two soil pits and thirty-four roadcut locations within the dispersion train. Soil and till samples were sieved into four size fractions; the resultant -212 micron (-70 mesh) fraction of each sample was analysed for Au by FA-AAS. Humus samples were ground to -100 micron powder and analysed for Au by INAA. Based on the analytical results, each LFH, A, B and C horizon was subdivided into anomalous and background populations. Detailed size and density fraction analysis was carried out on soil profiles reflecting anomalous and background populations, and a mixed group of samples representing the overlap between both populations. Samples were sieved to six size fractions; three of the size fractions (-420+212, -212+106, -106+53 microns) were separated into two density fractions using methylene iodide and analysed for Au by FA-AAS. The Au content of the -53 micron fraction was analysed by FA-AAS and cyanide extraction - AAS. Results indicate that the Au content of soil profiles increase with depth while decreasing with distance from the minesite. Heavy mineral concentrates and the light mineral fraction Au abundances reveal that dilution by a factor of 3.5 occurs within the till over a distance of 800 metres. However, free gold within the heavy mineral fraction is both diluted and comminuted with distance. Recombination of size and density fractions indicate that the Au contents of each size fraction are equivalent; variation in Au abundance is not observed with a change in grain size. Seventy percent of the Au in the -53 micron fraction occurs as free gold. Chemical activity has not altered the composition of gold grains within the soil profiles. Compositional and morphological differences between gold grains are not indicative of glacial transport distance or location within the soil profile. Relative abundances of gold grains between sample locations can be used as an indicator of proximity to the minesite. The sampling medium with the best sample representivity and contrast between anomalous and background populations is the -53 micron (-270 mesh) fraction of the C horizon. Geochemical soil sampling programs in the vicinity of the Nickel Plate mine should collect a minimum mass of 370 grams of -2000 micron (-2 mm) soil fraction in order to obtain 30 grams of the -53 micron fraction. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

Evolutionary divergence in Philonema (Nematoda; Philometridae) parasites of B.C. salmonids

Clease, Derek Fraser January 1990 (has links)
Philonema (Nematoda; Philometridae) from anadromous hosts, sockeye salmon (Oncorhynchus nerka), and non-anadromous hosts, rainbow trout (Oncorhynchus mykiss) , were studied in order to determine if hosts with different life histories were infected with the same or different species of Philonema. Worms from the two host species were morphologically indistinguishable. However, electrophoretic banding patterns produced by restriction enzyme digestion of DNA extracted from Philonema demonstrated the presence of two genetic types corresponding to the two host species. This supports the idea that at least two species of Philonema are endemic in British Columbia. Philonema oncorhynchi Kuitunen-Ekbaum, 1933 is a parasite of sockeye salmon which undergo a long ocean migration before returning to freshwater to spawn, while P. agubernaculum Simon and Simon, 1936 is a parasite of rainbow trout (and other salmonids) which live in lakes. Kokanee (O. nerka kennerlyi), a non-anadromous offshoot of sockeye, were infected with the same worm as sockeye probably because the two hosts have similar life histories. Steelhead smolts, anadromous O. mykiss, contained worms identified as P. agubernaculum. This likely represented an accidental infection because steelhead do not usually contact Philonema. Philonema were examined from various localities in B.C. Philonema agubernaculum showed population divergence corresponding to the different geographic localities from which it was collected. This likely reflects the isolation of these parasite populations in unconnected watersheds. Philonema oncorhynchi showed polymorphisms spread throughout many of the populations. The lack of population divergence probably results from gene flow between parasite populations brought about by wandering hosts. / Science, Faculty of / Zoology, Department of / Graduate

History and evolution of salmon aquaculture siting policy in British Columbia

Galland, Daniel 11 1900 (has links)
Salmon aquaculture is the rearing of salmonids for commercial purposes. These practices are typically carried out in saltwater farms located in coastal waters. The process of siting these facilities requires identifying and selecting areas that are economically, socially and environmentally suitable to locate them. Siting salmon aquaculture facilities has become a controversial resource management issue in British Columbia (B.C.), where distance-based criteria ultimately determine the location of these facilities. This thesis focuses on providing insights and concepts to inform and examine the salmon aquaculture facility siting process in B.C. It is argued that regulatory processes and outcomes in the context of a new industry could respond to mechanisms and factors that shape governmental agendas, illustrating how policy can behave reactively rather than in a precautionary manner. In this case, the outcomes of such reactive policies are reflected in siting criteria that yield implicit environmental and socio-economic disadvantages and tradeoffs. This way, siting criteria derive from expert judgements based on best available information while their associated uncertainties may lead to consider less-desirable sites while underestimating or overestimating risks, and overlooking important regional objectives, cumulative impacts and stakeholder values. The thesis further suggests that the future evolution of the salmon aquaculture facility siting process in B.C. could benefit from siting processes that have already been developed and implemented by other sectors. Different lines of reasoning that deal with processes of public negotiation, analytical decision-making and a systems' approach are explored as ways by which the salmon aquaculture facility siting process could evolve in the future toward creating more comprehensive policy. / Science, Faculty of / Resources, Environment and Sustainability (IRES), Institute for / Graduate
