Community development is described as a purposeful learning process whereby people identify their situation and plan and implement appropriate responses to it The original development strategies that have been applied to the Northwest Territories have been overwhelrningly modeled after the Western economic model,...

Social contacts as modifiers of diurnal cortisol production : a potential pathway between social relationships and health

Cinnamon Ashley Stetler
Social connections have been linked with morbidity and mortality across decades of research. Although stress buffering and health behavior models have been extensively detailed as pathways for this effect, the direct effects of social contacts on physiology have received less attention. Social contacts may help to regulate biological rhythms, particularly within the hypothalamic-pituitary-adrenal (HPA) axis, a hormonal system known to be influenced by the social environment. Dysregulation of the HPA axis has been associated with...

The social and lyric voices of Dorothy Livesay

Charles Robert Boylan
This thesis is a study of the growth and development of an important contemporary Canadian poet, Dorothy Livesay. I attempt to show that common to her personal, lyrical poems and her social documentaries is a democratic and humanist sensibility. Her purpose as a writer is to communicate with Canadians her responses to contemporary life as she experiences and feels it. Her perspective is that of a sensitive and critical mind, conscious of injustice and the...

Relationship of augmented feedback and directed practice in the improvement of typewriting accuracy

Frederick Charles Rankine
The problem of this study was to determine what effects the experimental manipulation of augmented feedback, remedial practice, and their combination have for the improvement of typewriting accuracy. The problem was generated from the research literature on skill learning which points out the efficacy of supplying additional information to students undertaking improvement in the skill area. The pertinent literature dealing with typewriting fails to take advantage of the psychological principles found useful to skill development....

The grievance field; an empirical study of grievance processes in a plywood factory

Brian C. Murphy
There are three major facets to industrial employer-employee relations: work processes, collective bargaining and grievance processes. The form of the first is established mainly at the initiative of the employer. The second is generally initiated by employee organizations and results in a document called a collective agreement which sets forth agreed upon patterns of interaction between employer and employee. The third, Grievance Processes, are the means whereby individual and group differences of opinion regarding interpretation...

Numerical model of wave effects on permeable vertical barriers above the seabed

Gang Yang
This thesis describes a numerical model used to predict the interaction of a regular small amplitude wave train with a thin permeable vertical barrier extending from the water surface to some distance above the seabed. The case of wave interactions with a pair of such barriers is also treated. The approach used is based on an eigenfunction expansion method and utilizes a boundary condition at the barrier surface which accounts for energy dissipation within the...

Dynamic Bayesian networks

Michael C. Horsch
Given the complexity of the domains for which we would like to use computers as reasoning engines, an automated reasoning process will often be required to perform under some state of uncertainty. Probability provides a normative theory with which uncertainty can be modelled. Without assumptions of independence from the domain, naive computations of probability are intractible. If probability theory is to be used effectively in AI applications, the independence assumptions from the domain should be...

Aspects of structure in Olivier Messiaen’s Vingt regards sur l’Enfant-Jésus

David Rogosin
The paper explores various structural aspects of the 1944 masterwork for piano, Vingt Regards sur I'Enfant-Jesus, by Olivier Messiaen (1908-1992). Part One examines elements of the composer's style in isolation, focusing principally on the use of the modes of limited transposition to generate diverse tonal styles, as well as the use of form and "cyclical" or recurring themes and motifs to both unify and diversify the work. The author divides Messiaen's tonal styles into three...

The effects of artificial diet on gonad size, egg size, egg quality, and larval vitality in green sea urchins, Strongylocentrotus droebachiensis of aquaculture significance

M. Marja De Jong Westman
Effects of long-term dietary conditioning on gonadal growth, lipid, and moisture content, and on egg size, egg-energy content, larval morphometry, and larval development of the green sea urchin Strongylocentrotus droebachiensis were studied in the laboratory. One algal and seven artificial diets were tested over a nine-month period, coinciding with the urchin’ s annual reproductive cycle. Formulated diets differed in protein level and in the presence or absence of different supplements, such as algal storage carbohydrates...

Cluster-based information retrieval modeling

Richard Sze
Cluster-based information retrieval, an extension of information retrieval strategy, is based on the assumption that a document collection can be organized into a set of topics so that a user can enhance retrieval effectiveness. The cluster-based IR model assumes that queries can be associated with clusters that contain high concentrations of relevant documents, and that such association can lead to gains in retrieval effectiveness. Earlier studies, however, have provided negative to mixed results for the...

Some factors affecting the extraction of sulphate from selected Lower Fraser Valley and Vancouver Island soils

Aldwyn Louis Bart
A study was undertaken to determine some of the factors which affected the extraction of sulphur from seven selected soils of the Lower Fraser Valley and Vancouver Island; with particular reference to the effect of pH, concentration and cation of phosphate buffers. In all cases the presence of phosphate resulted in more sulphur being extracted, than extraction with water only. In every instance increasing the concentration of neutral sodium phosphate buffers from 0.005M to 0.5M...

Penetration of CFRP laminates by cylindrical indenters

Daniel O. Ursenbach
The main focus of this thesis has been towards understanding the local penetration behaviour of a CFRP laminate undergoing quasi-static out-of-plane loading. This information is necessary for predicting dynamic impact behaviour. An experimental program was performed that characterized the damage mechanisms occurring during penetration and confirmed the validity of model assumptions. The principal test consisted of a 7.62 mm diameter blunt-nosed cylindrical indenter penetrating various thicknesses of CFRP coupons supported over a rectangular opening. Even...

A peel adhesion test for thermal spray coatings

Michael Sexsmith
In order for the thermal spray industry to progress, informative and reliable coating evaluation techniques are needed. The measurement of adhesion is an important problem and existing tests have severe limitations. A peel adhesion test has been adapted to thermal spray coatings from the adhesives industry which should address this problem. In a peel test, a thin metal foil is coated by plasma spraying. The foil is then peeled off of the coating at a...

Heat transfer in the roll gap during hot rolling

Craig Ohrist Hlady
A series of pilot mill hot-rolling tests involving AA5052, AA5 182, and copper samples has been performed. These rolling tests encompassed a range of rolling pressures, rolling speeds, reductions and temperatures. In addition, two types of lubricants were employed in the hot rolling of the aluminum alloy samples. Instantaneous roll-gap heat-transfer coefficients (HTCs) have been calculated from roll-gap surface temperature measurements. These measurements were made from double-intrinsic thermocouples secured on the surface of the samples....

Deformation and fracture behavior of eutectic aluminum-silicon casting alloys

Eric James Dowdle
The effect of silicon particle size and morphology on the deformation and fracture behavior of a binary aluminum silicon casting alloy was studied. Castings of eutectic composition were solidified either slowly without modifiers, or quickly with strontium modification to produce two different as-cast microstructures. Solution treatment of the castings was performed for various lengths of time at 540°C to further differentiate the structures. Quantitative image analysis was used to describe the size and shape of...

Integrated approach for accurate quantification of methane generation at municipal solid waste landfills

Ali Reza Abedini
Municipal solid waste (MSW) landfills have been identified by regulators and policy-makers as primary sources of greenhouse gas (GHG) emissions. Landfill gas (LFG) generation is best described as a first order reaction which is the basis of many LFG generation models. These models are tools to predict a landfill’s lifespan methane generation, in lieu of costly full scale quantification methods. Moreover, modeling results are required to properly design LFG recovery and utilization systems. These results...

The influence of red alder in adjacent conifer stands : nutrient cycling and light transmission

John Meredith Lavery
Red alder (Alnus rubra(Bong.)) is an important successional deciduous species in British Columbia with expanding commercial markets. Alder is a pioneer species which grows rapidly on disturbed sites and in riparian areas of coastal British Columbia. Alder's impressive early height growth and ability to increase the rate of cycling of nitrogen and other nutrients lead to a challenge in managing alder with conifers. Managing alder in mixedwood stands requires finding an appropriate balance between competition...

Joanna E. Ashworth
This research aims to disrupt and expand "given" understandings of educational leadership by exploring particular leadership instances of the everyday practice of adult education. Seven adult educators, including the author, offer narrative accounts of planning, designing, teaching, managing, and creating programs for adult learners with a particular interest in the little examined dimension of practice - educational leadership. The author works with the conceptual resources of Hans-Georg Gadamer's philosophical hermeneutics, primarily through the theoretical, evocative,...

Formation of functional selectin ligands on activated T cells and thymic progenitors : the role of core 2 β1,6-N-acetylglucosaminyltransferases in the control of lymphocyte trafficking and thymic progenitor homing

Jasmeen Sayed Merzaban
The core 2 β 1,6-N-acetylglucosaminyltransferase (C2GlcNAcT) family of enzymes (C2GlcNAcT-I,-II,-III) synthesize branched O-glycans. A significant body of work highlights the importance of C2GlcNAcT-I in controlling selectin-ligand-mediated cell trafficking while little is known about the role of the two other C2GlcNAcT isoenzymes. 1) The first objective of this thesis is to determine in vitro and in vivo T cell stimulation conditions that guide P-selectin ligand expression in absence of C2GlcNAcT-I. Mitogen stimulation of splenocytes maintained under...
