abstract: In wireless telecommunications, antennas play a very important role where they can either enhance or constrain system performance. The design characterization of such antennas is dependent upon, to large extent, the development of simulation tools that can accurately model general antenna system topologies. In this thesis, where the basic theory of finite-difference time domain method (FDTD) is reviewed, an FDTD code is developed for antenna design, with particular emphasis on the modeling of the source region. The results from the developed code are compared with those produced by a moment method based code (Numerical Electromagnetic Code -2: NEC2) and very good agreement is obtained. The effects of the FDTD cell size and the distance between the outer absorbing boundary and the antenna on accuracy are explored. Some criteria for the choice of above parameters in FDTD calculation are given for antenna design. Using the developed code, a new planar monopole antenna which operates at dual wide band (800MHz band and 1800MHz band) is developed by cutting slots and determining the geometrical parameters. This dual frequency performance is required for the existing and potential mobile communication system providing analogue and digital services.

type: Thesis NonPeerReviewed

abstract: From April 26 to July 27 1999 I conducted field research in Glastonbury England. During this period, I studied the manifestation of alternative religious beliefs and the provision of alternative healing in the context of seven alternative Bed and Breakfast accommodations. The following thesis probes issues relating to the manifestation of the alternative identity of these establishments, the characteristics of alternative healing in the B&B's, and the nature of health and healing as understood by proprietors of these accommodations. Further, I examine the importance of the physical, spiritual and symbolic landscape of Glastonbury to the practice of healing. I also discuss the nature of the town as a centre of 'alternative' pilgrimage in relation to the model proposed by anthropologist Victor Turner. Lastly, I explore the nature of tourism in Glastonbury and the tensions which exist between the alternative spiritual world of the B&B proprietors and the secular world represented by the Tourist Board.

abstract: La personnalité de Simone de Beauvoir est analysée du point de vue de la psychologie paradoxale. Celleci soutient que l'être humain peut faire l'objet de certaines réactions de défense gui ne peuvent pas être directement contrôlées, telle l'agitation ou la dépression, et que le meilleur moyen qu'il a de satisfaire un désir de retrouver ou de préserver sa maîtrise de soi est d'agir d'une manière qui la favorise, au lieu de réagir à l'excès contre des tendances indésirables et aller ainsi à l'encontre du but recherché par découragement ou frustration. -- Des exemples tirés principalement des volumes autobiographiques de Simone de Beauvoir (Mémoires d'une jeune fille rangée, 1958; La Force de l'âge, 1960; La Force des choses, 1963; Tout compte fait, 1972) et secondairement de ses romans souvent à forte teneur autobiographique (L'Invitée, 1943; Le Sang des autres, 1945; Tous les hommes sont mortels, 1946; Les Mandarins, 1954; Les Belles Images, 1966) sont présentés pour montrer que celle-ci fait l'objet de certaines tendances passives, lesquelles sont divisées en quatre catégories dans le cadre de cette recherche: tendances à se culpabiliser facilement, à être impressionnable, à perdre espoir facilement et à être scrupuleuse à l'extrême. Faisant en guelque sorte contrepoids à ces tendances passives, certaines tendances agressives sont également évidentes dans la vie de Simone de Beauvoir. Ces dernières sont de même classifiées en quatre groupes: tendances à blâmer facilement, à être facilement rebelle, à s'emballer et à être intransigeante. De plus, certains faits indiguent que Simone de Beauvoir a tenté de remédier à une tendance à l'irrésolution -tendance passive- par une tendance à l'obstination -tendance agressive, et vice versa, et parce que l'obstination finit par lasser et l'irrésolution irrite en fin de compte, elle a voué ses efforts à l'échec, cet échec pouvant être partiellement responsable d'un sentiment persistant de futilité qui l'a hantée tout au long de sa vie, plus ou moins épisodiquement. -- Cette thèse suggère que si Simone de Beauvoir n'avait pas généralement attendu d'être à bout pour agir, il lui aurait été peut-être plus facile de s'arrêter au moment voulu, et si elle avait été généralement capable de s'arrêter au moment voulu, il lui aurait été peut-être plus facile de se décider, et elle aurait ainsi peut-être trouvé une solution plus satisfaisante à sa "schizophrénie" (FA, p.97).

abstract: The excavation of four occupation areas at the Gould site (EeBi-42) in Port au Choix, northwestern Newfoundland offers new insight into the Recent Indian Cow Head complex (2000 to 1500 B.P.). New artifacts, including contracting stemmed projectile points and ceramic vessels are introduced as elements of the Cow Head assemblage and information about housing and settlement data indicate the use circular tent-like structures and the occupation of near-coastal areas. Also present is evidence that Cow Head groups participated in a broad sphere of inter-regional interaction that involved other coeval late prehistoric groups along the Lower North Shore of Quebec, central Labrador, and the Maritimes.

abstract: At rest lateral stress in soils is an important parameter in geotechnical applications. In the past decades, much work has been done on the investigation of the lateral stress in sands. However, little information regarding lateral stress in cemented sands has been reported. -- This thesis presents the results of a laboratory study on the at rest lateral stress and coefficient of at rest lateral stress (Kₒ) of cemented sands. A state of the art literature review is presented, in order to provide a background to the static and dynamic behaviours of cemented sands. A modified oedometer ring was used to measure the at rest lateral stress in cemented and uncemented sands. Test materials were No. 3 Ottawa sand and a marine sand, and portland cement. The specimens were prepared by the method of undercompaction using 0, 0.5, 1.0, 2.0, 4.0 and 8.0% of cement by the weight of dry sand. The water content of the specimens was 4% of dry sand and cement. The test program was designed to investigate the influences of cement content, vertical stress, sand density, curing period and stress history. -- The test results indicate that the lateral stress in cemented sand decreases significantly with increasing cement content. The value of Kₒ increases with increasing vertical stress. The lateral stress decreases with increasing sand density and curing period. Stress history also has a significant influence on the behaviour of lateral stress in cemented sands.

abstract:
Early feeding of low birth weight (LBW) infants with their own mothers' milk has been shown to decrease the incidence of oxygen radical related disease states. Milk from mothers of pre-term (PT) and full-term (FT) infants may exhibit antioxidant and free radical scavenging ability not provided by humanized formulas. This study investigated the ability of milk from weeks 1, 2 and 12 of lactation (17 PT and 28 FT mothers) to resist oxidative stress by free radical attack as compared to formula. The hypoxanthine/xanthine oxidase (HX/XO) system was utilized to generate the radicals and subsequent oxygen consumption was measured. The samples were also tested for catalase (CAT) activity, and for malondialdehyde (MDA) levels by HPLC following stress. As well, normal (3 mg/L) and high (12 mg/L) iron formulas were tested for their ability to resist oxidative damage with and without the presence of added antioxidant enzymes CAT, superoxide dismutase (SOD) and glutathione peroxidase (GSHPx). There was no difference (p > 0.05) between the PT and FT groups with respect to oxygen consumption (nmoles O₂/min) at any stage of lactation. The means ± SEM of O₂ consumption reported for the groups respectively following HX/XO stress, were for week one, 7.97 ± 0.56 and 6.68 ± 0.88; for week two, 4.62 ± 0.42 and 5.17 ± 0.36; and for week twelve, 4.08 ± 0.39 and 4.80 ± 0.49. There was also no difference in MDA levels or CAT activity between groups. This indicates that PT milk has similar antioxidant capability as FT milk. A correlation (r²= .443, p < 0.05) existed between O₂ consumption and MDA levels, and a negative correlation (r²= -0.30, p < 0.01) between the amount of oxygen consumed, and the activity of CAT for all weeks, demonstrating a possible protective role of this enzyme
in human milk (HM). A difference (p < 0.001) was reported in total O₂ consumption (nmoles) over time between the HM (44.75 ± 1.66) and both the normal (98.88 ± 3.11)and high-iron (168.94 ± 9.47) formulas. Addition of CAT, SOD and GSHPx together was shown to increase (p < 0.01) the antioxidant capacity of the normal and high-iron formula by decreasing the oxygen consumption to 66.11 ± 6.48 and 104.81 ± 8.65 respectively. Furthermore, the addition of Fe to HM resulted in an increase in O₂ consumption compared to HM controls providing an indication of iron as a free radical generator in infant formula. There was no catalase activity detected in the formula and upon pasteurization of the HM to inactivate the enzymes, antioxidant capability was not compromised.

abstract: The purpose of this study was to investigate the motives of women seeking therapeutic abortion in Newfoundland. -- The information for the study was collected through personal interviews with all applicants requesting termination of pregnancy between January 15 through March 1, 1979 till the target number, seventy-five cases, was reached. A structured questionnaire was administered to this sample consisting of all age groups among women of child-bearing age and both never-married and once-married women. -- A review of the literature on abortion revealed that the reasons for requesting termination differ between single and married women. In addition to age and socio-economic factors, the relationship with the partner is decisive for the outcome of the pregnancy for the former group, while poor health, financial problems, being past the child-bearing age, etc. are common reasons for the latter group. -- The central proposition stated that the reasons given by a woman for terminating her pregnancy will be closely related to her age, marital status, relationship with the sex partner and other socio-economic factors. -- An analysis of the findings supported the central proposition although statistical significance was not reached. -- The general conclusion arrived at was that termination of pregnancy is a highly personal decision and usually consists of a variety of complex factors. It was also noted that marriage for the sake of legitimising the pregnancy is being rejected as a viable solution by many. Single young women, in particular, place emphasis on being older and more mature to cope with motherhood and its responsibilities, as well as on financial security. Among married and older women, breakdown in marriage, ill health and being past the child-bearing age are the frequent reasons given. -- These findings are relevant to social workers and other personnel who work with abortion clinics, family planning centres, etc., in that they provide some measure of understanding of the population that seeks this service, so that appropriate counselling may be provided. Statistics indicate an upward trend in the incidence of abortions drawing attention to the need for competent contraceptive knowledge. Further research is, therefore, required to explore the contraceptive practices of this population for the purpose of providing preventive treatment, particularly to high-risk groups.

abstract: A robust method for the estimation of limit loads of structures has been adopted for plate structures. It involves the use of modified secant rigidity. The method makes use of repeated linear elastic analyses to predict limit behavior. The results from an initial elastic analysis are used to obtain the principal moments. A suitable yield criterion (such as Tresca or Von Mises) in terms of generalized forces is used. A set of equivalent moments is then computed for the plate. This is used to modify the secant rigidity of the plate. The modified structure is re-analyzed iteratively until convergence is reached. The moment distribution from the convergent analysis shows the collapse mechanism for the plate. The average of the equivalent moments along the collapse (or yield) lines of the plate is scaled to the plastic moment capacity of the section to obtain the limit load factor. The method has several advantages in comparison to other traditional methods. -- This method has been implemented on ANSYS software using APDL routines. Problems solved include: simply supported and fixed square and circular plates with uniform and concentrated loads, plates with irregular boundary conditions and shapes as well as continuous plates with checkerboard loading. The results from the above analyses match analytical results very closely, thus demonstrating the usefulness of the method used.

abstract:
An experimental study has been conducted to investigate two-phase slug flow and the closure problem of two-phase flow models. To investigate the problem experimentally, a 3-inch ID and 180-foot long close loop re-circulation multiphase flow research facility was constructed at the Fluids Laboratory, Memorial University of Newfoundland (MUN). Accurate instrumentation of this facility makes it suitable for both conducting multiphase flow research and testing multiphase flow measurement systems. A new flow pattern map has been developed based on dimensional analysis. The functional equation governing the flow pattern formation was analyzed to yield the proper dimensionless plotting parameters. The use of these parameters makes the resultant flow pattern map independent of flow geometry and fluid physical properties. Data collected from the MUN flow loop as well as from the literature were used to generate the new flow pattern map. Flow pattern boundaries were systematically determined using a pattern recognition technique. -- The second part of this study is focused on vertically upward concurrent slug flow. A simultaneous flow measurement system using both dual-probe hot-film anemometry and high-speed flow visualization was used to obtain the quantitative flow information. To discriminate the signal into the gas and liquid phases, a combined amplitude and first-order time derivative phase detection method has been developed. The void fraction of the flow was estimated from the resultant phase indicator function. An innovative data reduction technique using wavelet analysis combined with the phase detection method was developed to decompose the original signals into signals corresponding to air slugs and small air bubbles. This technique results in two velocities corresponding to slugs and bubbles from cross-correlation analysis of the discriminated signals. Slug/bubble velocities, slug/bubble sizes, slug/bubble frequencies and slug/bubble void fractions were also estimated from the decomposed signals. Slug flows under a variety of flow conditions were investigated to yield a detailed description of the flow. The calculated mean velocities of air slugs, bubbles and liquid slugs are slightly lower than those predicted by the correlations in literature. Necessary modifications of these models were, therefore, recommended. Models for predicting void fraction, slug
void fraction, slug/bubble dimensions and bubble frequency were also developed. The results obtained from the hot-film signal processing technique were verified by the two image processing methods. -- A technique for approximating the interfacial area concentration from a single normal probe was proposed in this study. Comparison of the measurements conducted in this study with the reported interfacial area concentration models developed based on bubble flow indicates that these models are not suitable for slug flow. An interfacial area concentration model was, therefore, formulated for slug flow based on the synthesis method. The proposed correlation indicates that the interfacial area concentration is closely related to flow and fluid properties. In summary, the study presented in this thesis provides a detailed quantitative flow description and information for formulating accurate constitutive equations for vertically upward air-water two-phase slug flow.

abstract: An analysis is performed to determine the intrinsic economic value of four potential forest industry developments for the Goose Bay area of Labrador and their relative attractiveness to investment. These are a newsprint mill, an integrated newsprint mill and sawmill, a chemithermo-mechanical pulp (CTMP) mill and an integrated CTMP mill and sawmill. -- Prior to carrying out the analysis, a review is made of past attempts to develop the forest resources of Labrador, the choice of these four particular forest industry options is explained, and key considerations to the development of these options are discussed. -- The analysis employs discounted cash flow (DCF) criteria for evaluating these investments, eg. rate of return (ROR), net present value (NPV), and others. A computer model developed by the author is used to assist in the analysis. The industry options are first evaluated under base case conditions in which it is assumed that these projects would be financed only by investor equity. The sensitivity of base case results to potential changes in components of interest is then evaluated. This allows determination of the relative importance of all factors, and consequently also determines what leverage is available to Government and prospective developers for improving the attractiveness of these investments. -- Under base case conditions, none of these investments meets the minimum criteria for investment. Moreover, the results indicate that an integrated newsprint mill and sawmill or an integrated CTMP mill and sawmill are less attractive investments than a newsprint mill or CTMP mill alone. These options are therefore, eliminated from further analysis. Penalties and benefits associated with locating in Labrador are quantified in terms of ROR and it is concluded that there is a net penalty in each case. The potential for debt financing to overcome these net penalties and to make these projects meet the minimum criteria for investment is examined along with various forms of financial incentives available to Government, eg. tax relief, subsidies, grants, loan guarantees. It is concluded that these measures have the potential available for making a newsprint mill or CTMP mill development in the Goose Bay area of Labrador an attractive investment.

abstract: This thesis examined two issues with respect to subjective well-being. These issues were: a) enhanced prediction of subjective well-being by the use of multiple predictor classes, and b) the relationship between subjective well-being and it's predictors. Two hundred seventy-seven participants ranging in age from 18 to 48 years were administered the Memorial University of Newfoundland Scale of Happiness (MUNSH), the Satisfaction with Life Scale (SWLS), the NEO Five-Factor Personality Inventory (NEO-FFI), a daily hassles and uplifts scale, two personality resource measures, and a domain satisfactions scale. Simultaneous examination of various predictor classes enhanced prediction of subjective well-being. Environmental variables, life domains, personality resources, and personality traits accounted for 59% of total variance in subjective well-being as measured by the MUNSH. However, only environmental variables, life domains, and personality resources made an independent contribution to an explanation of SWLS variance. In combination, these variables account for 48% of variance in SWLS scores. As in past research, a bi-directional model which includes both state (bottom-up) and trait (top-down) effects best explains the relationship between predictors and subjective well-being.

Masters thesis, Memorial University of Newfoundland.

abstract: The closely related, endangered Braya longii and threatened Braya fernaldii (Brassicaceae) are endemic to the limestone barrens of the Great Northern Peninsula of Newfoundland. This project determines potential breeding systems, levels of population differentiation, potential hybridization between these species and implications for conservation management. Morphological species differences are also summarized to ensure proper identification of new populations. Results indicate field identification using only single morphological characters is insufficient to unambiguously identify species. Both species were found to be primarily autogamous but B. longii has a greater potential for outcrossing than B. fernaldii. Cleistogamy was found to occur within some populations of B. fernaldii, but not in B. longii. Evidence of population differentiation in floral morphology was found for both species and potential hybridization was indicated by floral morphology and hand-pollinations. The results of this study provide guidance for potential conservation management tools and must be addressed before reintroduction and population restoration are implemented.

abstract: This study examined the School Assessment Model as was piloted in the Province of Newfoundland and Labrador. The intent of the study was to attempt to gather information related to this model of School Reform and to gain an understanding as to why it was an assessment based model that was promoted as opposed to an accreditation based model. Information was gathered through the assistance of a targeted research sample group. A semi structured interview was conducted with each of the participants and questions revolved around ascertaining the level of commitment to reform, the need for reform, the differences between School Assessment and other previous reform initiatives, and the benefits and challenges for the Provincial Department of Education, school districts and schools in supporting school assessment at this time. -- The results of the study indicated that a large reason for the promotion of an assessment based model was that the education system in this province with its geographical constraints, history and financial restrictions, would be more conducive to an assessment based model. Assessment based reform is, at this time, a better fit for the education system in the province. The indication was given by several subjects that they felt an accreditation type model would be revisited in the future.

abstract: School violence is defined as anything that makes a student afraid to come to, and stay at school (Macdonald, 1996). Media reports of the suicides of children who were the victims of bullying, school shooting rampages in Littleton, Colorado and Tabor, Alberta, and the beating death of Rena Virk have brought the problem of school violence to the forefront. What follows is a series of three papers that attempt to inform school counsellors, and others working in the school system, about school violence and the actions that may be taken to ensure that every student is provided a safe learning environment. Paper one describes the current views held about youth and school violence. This includes a discussion of the forms, perpetrators, incidence, and risk factors for violence. Paper two concentrates on the prevention and intervention measures that can be implemented at the family, community and school levels. Finally, paper three focuses on the role the guidance counsellor can play in the school environment to help make it a safer place for students to learn.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: In 1933, an American entrepreneur offered the people of St. Lawrence, a small town on the south coast of Newfoundland, the prospect of escaping rampant unemployment and meager public relief by starting a mine to extract the area's vast deposits of fluorspar, which is used in the manufacture of steel, aluminum, and various chemical products. Coming in the context of the Great Depression and the collapse of the fishing industry, the mining industry was eagerly embraced by residents of St. Lawrence and surrounding communities. Several mines were subsequently established, by both the original American company, the St. Lawrence Corporation of Newfoundland, and later by the Aluminum Company of Canada (Alcan). The fragile prosperity that accompanied the industry from the 1930s until closure of the last Alcan mine in 1978, however, exacted a heavy price. Many St. Lawrence workers lost their lives to industrial diseases caused by dust and radiation in the mines. -- This thesis explores the history of industry, labour, and health and safety at the St. Lawrence mines. This study focuses on the struggle by workers and their union for recognition of workplace hazards, improved working conditions, and adequate compensation for industrial disease victims and their families. The thesis argues that, rather than being passive victims of an unavoidable tragedy, workers at St. Lawrence were aware of the adverse health impacts of their work from the very early years of mining, and fought constantly over several decades to have their concerns addressed. Furthermore, the thesis argues that the disaster which ultimately unfolded at St. Lawrence was primarily the result of industry and government authorities ignoring or downplaying legitimate concerns and thereby shirking their moral and legal responsibilities.

abstract: L. monocytogenes is ubiquitous in nature, has been isolated from many different types of food, has human health implications and can survive at very low temperatures. Additionally, the infectious dose of the pathogen is unknown, thus this bacteria is a concern in ready-to-eat seafood products. Currently, there is a lack of available information on the thermal resistance of Listeria monocytogenes in seafood, particularly in shrimp (Pandalus borealis), and on the pathogen's behaviour under different conditions of storage in seafood products. Furthermore, due to the lack of available data, it has been quite difficult for guidelines, regarding the processing times and temperatures required to control the presence of L. monocytogenes in foods, to be established. Hence, this study investigated the behaviour of L. monocytogenes on inoculated raw shrimp stored at -20°C, on ice (0-1°C), 4°C and 10°C and examined its thermal resistance in shrimp. Additionally, the total aerobic colony count and incidence of L. monocytogenes on raw shrimp was examined. -- Low levels of total aerobic bacteria, averaging 429.8 CFU/g, were found on the raw shrimp and no L. monocytogenes cells were isolated from the samples. For the storage experiments, shrimp samples were inoculated with low (10² CFU/g) and high (10⁶ CFU/g) levels of the bacteria and stored at the various temperatures in sealed plastic bags. Overall, L. monocytogenes was able to survive, but not grow, when stored on shrimp at -20°C and on ice (0-1°C). However, the pathogen was able to grow, quite significantly, when stored at temperatures of 4°C and 10°C, with generation times of 3.60 and 3.08 min at 4°C and 1.1 and 1.96 min at 10°C, for low and high inoculation levels, respectively. The highest increase in L.monocytogenes numbers was on shrimp inoculated with 10² CFU/g of the bacterium and stored at 10°C. Hence, refrigeration and freezing are no safeguards against this pathogen. -- For the thermal resistance portion of this study, the capillary tube method was used. Triplicate thermal inactivation trials were carried out and D and z values determined for temperatures of 65, 68, 70 and 72°C. L. monocytogenes were enumerated using both Listeriaselective agars, Oxford and PALCAM, and a non-selective agar, TSA. D values were calculated using D = -slope⁻¹, obtained from the linear regression analysis of the survivor curve (log₁₀ survivors vs. time). Average D values obtained in this study for L.monocytogenes in shrimp were 0.591, 0.266, 0.144 and 0.0202 min, for temperatures of 65, 68, 70 and 72°C, respectively. A z value of 5.07°C was also determined. Also, D values of 5.73, 2.31, 0.0063 and 0.00065 min were predicted for 60, 62, 75 and 80°C, using the D values and z value obtained from the experiments. The results of this study are compared to those of other studies.

title: Risk evaluation in resource allocation

abstract: The conventional resource allocation procedures implicitly assume that availability of resources is certain. In real life situations. their availability at times is uncertain. A simple model is required to categorize and quantify the uncertainty due to resource availability and evaluate its impact on project schedule and cost. This thesis proposes a Risk Evaluation Model (REM) which takes a resource justified schedule as input, incorporates the uncertainty associated with availability of resources, and generates alternate sets of values on project completion time, cost and performance probability. It will help select a resource justified schedule which has not only the least duration or cost but also reasonable performance probability.

Bigelow) : a study of the effects of salinity on germination, growth, photosynthesis, and respiration in comparison to common forage legumes.  Masters thesis, Memorial University of Newfoundland.

abstract: Beach pea (Lathyrus maritimus (L.) Bigelow) is a lush green legume which grows along the shores of the island of Newfoundland. It is a circumpolar plant found on both sea shores and the shores of freshwater lakes. Beach pea is a fleshy perennial with an extensive rhizome system. The roots form nodules that contain bacteria (Rhizobium sp.) which provide fixed nitrogen to the legume for incorporation into proteins of the host plant. Beach pea form large persistent stands on beaches and has been studied for its potential as an alternate forage crop. The plants that grow on salt water beaches are exposed to salt water spray inferring some level of salt tolerance in the plant. The objectives of the thesis were to compare salinity effects on beach pea germination relative to other forage crops and to study salinity effects on growth. -- Slightly increased salt concentration delayed beach pea germination more so than that of alfalfa and red clover, contrary to the initial hypothesis that beach pea germination would show higher tolerance for saline environments. Red clover and alfalfa were affected only at salt concentrations of 1.75 and 2.0 percent whereas beach pea germination was affected at 0.50 percent salinity. Final germination percentage relative to germinating salinity followed a sigmoidal pattern in all crops, dropping rapidly around 1.0 percent NaCI. Growth in saline environment effectively stopped the growth of beach pea by limiting stem elongation, new stem initiation, and new leaf initiation. Alfalfa mortality was observed as a result of the saline environment with a 50 percent mortality in the 2 percent saline environment 10 weeks after planting and 100 percent at 15 weeks. The 1 percent saline environment also increased mortality in the alfalfa to 60 percent by week 16. Control plants showed no mortality over the 16 week experiment. -- The delay of germination and inhibition of new growth seen in the beach pea did not support the hypothesis of the experiment. Salinity measurements of the natural beach environment showed low soil salinity level relative to salinity in the tide line. At the high tide line salinity was 20 times higher than the salinity in the beach pea stands. The experiments show that the environment in which beach pea grows is not saline. Salinity delays germination but the plants, once established, are salt tolerant. In a natural stand of beach pea exposure to a saline environment would be temporary as fresh water from rain or seeps would remove the salt before any accumulation and thus plant damage could occur.

abstract:
The lingonberry or partridgeberry, Vaccinium vitis-idaea L. var. minus Lodd, is a low-growing ericaceous shrub, which produces edible berries that ripen in Newfoundland in mid-September. Grapholita libertina Heinrich, the lingonberry fruitworm, is a tortricid moth whose larvae feed within the lingonberry fruit. -- The objectives of this study were to identify sex attractants for G. libertina and to evaluate its use in monitoring and controlling populations in wild Newfoundland lingonberry fields. A synthetic sex attractant was developed from among chemicals attractive to other Grapholita species and tested in 1997 to monitor G. libertina populations. Identification of this attractant led to a series of questions. Could this attractant prove useful in estimating future larval infestations? What would be the most effective delivery system for this attractant? Could field trapping accurately predict flight? How similar is the synthetic male attractant to the naturally occurring female produced pheromone? -- Field trials were conducted with the sex attractant in 1998, 1999 and 2000 to correlate the adult trapping rate with the subsequent densities of larvae and damaged berries to examine the effects of berry distribution and heterogenous vegetation coverage in the wild. Trials in 1999 were conducted to determine the most effective trap design for monitoring G. libertina. The efficacy of mass trapping using sex attractants of G. libertina was tested in 2000 as a potential control measure. In addition, information on
population trends and phenology of G. libertina were examined through recording of the flight season, degree day accumulations and population size. Field-collected G. libertina were reared in order to identify the naturally occurring female sex pheromone. Solid phase microextraction was used to collect insect effluvia and gas chromatography-mass spectrometry attempted to identify pheromone components and relative amounts in the pheromone blend. -- The results of this study indicated that a blend of: 85% E-8-dodecen-1-ol acetate, 10% Z-8-dodecen-1-ol acetate, and 5% Z-8-dodecen-1-ol was a suitable synthetic sex attractant for male G. libertina. The adult capture rate in Pherocon 1 C® wing traps was correlated with subsequent larval and damaged berry density in wild fields. Berry densities were important in determining the distributions of larvae and damaged berries when berry levels were low (1999), perhaps indicating that a limited or patchy host berry distribution affected female oviposition. Heterogenous vegetation present at study sites showed no significant effects. -- The Pherocon lC® wing trap was the most effective for use with the 85:10:5 blend. Mass trapping indicated a possible disruption of mate location by G. libertina, however no significant decrease in larval populations was noted. As a result of trapping, it was established that the adult male flight season extends over 6 weeks from late June to early August. The number of degree days above base 5° C required for 10% emergence was recorded as 270±20.5 by rearing, and 334±8.1 by field trapping. Identification of the female sex pheromone by gas chromatography- mass spectroscopy was not successful.

abstract: The wear of SAE 1080 steel under the conditions of unlubricated sliding is studied. The ranges of normal force and speed are 295-980 N and 0.193-1.544 m/s respectively. The specimen configuration adopted is of two coaxial hollow cylinders, 18.42mm mean diameter, rubbing at their annular end faces 2.54mm wide. -- The environment of the rubbing surfaces is controlled by forcing air or oxygen-argon mixture between the specimens. The vibration in the machine is measured. -- Wear debris particles are identified by x-ray diffraction and their size distribution determined. Wear surfaces are studied on an Optical and a Scanning Electron Microscope. -- It appears likely that wear rate is governed by oxidation of an area at a little distance from the hot spot. A correlation has been found between the sliding speed which in turn affects the surface temperature with the wear rate. The surface topography is shown to be a function of speed. -- In an environment of inert gas, the wear is of a severe type. When different mixtures of oxygen and argon gas are forced through the specimens, a significant change in the wear rate is observed. -- The difference in mean temperature of the two rubbing specimens influences the wear rate. The specimen at higher temperature shows lower wear rate.

abstract: A second design loop in the development of the computer controlled oscillating motion apparatus was completed as a part of this research. Specifically, work was concentrated in two areas: first, modifications to the existing motion control software with the aim to produce a continuous sinusoidal motion, and second, design of a dynamometer to measure more accurately the thrust developed by the oscillating foil. -- Bench tests conducted with the changes in the motion control indicated that the limitations to produce true sinusoidal oscillatory motion were due to the oscillating apparatus drive system. A single degree of freedom dynamometer consisted of two flexible vertical sheets to which a rigid plate was connected forming a U frame. This design allowed for sensitivity in the fore and aft direction, but was very rigid in the transverse direction. The oscillating apparatus was supported by the frame, and thrust or drag forces developed by the oscillating foil were transmitted through this frame to the load cell. -- An experimental study to measure developed thrust from a series of rigid foils subjected to unsteady, oscillatory motion has been conducted in the towing tank at Memorial University of Newfoundland. The foils tested consisted of a rectangular planform, a straight tapered and swept back planform, as well as the planform with curved leading edge, similar to the flukes of a fin whale. The foils had the same aspect ratio of 6. Two foils were fabricated out of brass, and another was made out of wood. The brass foils had a span of 200 mm, while the wooden foil had a span of 400 mm. In the experiment the heave amplitude to chord ratio was large (of order 1) and the pitch amplitudes tested were :6, 13, 17.5 and 21 deg. The pitching axis position was fixed at chord/2, and pitch led heave by 90 deg. -- Results of developed thrust from different planforms are presented and examined with respect to four areas of interest: large amplitude motion, effects of different planforms on developed thrust, foil performance at large angles of attack, and a comparison of an existing 3D unsteady flow panel code to predict developed thrust with the experimental results. -- Comparison of experimental results with the panel method showed that for small reduced frequencies and angles of attack, agreement in the magnitude of the thrust coefficient was good. At large reduced frequencies and angles of attack results from the panel method underpredicted the developed thrust. This discrepancy in results was due to separation and dynamic stall which occurred in the range of 33 to 40 deg. angle of attack. The combination of a leading edge sweep and taper of the foil's planform has a marked difference in developed thrust compared to the foil with a straight leading edge. This was due to different stall behaviour over foils with leading edge sweep compared to the stall of foils with a straight leading edge.

abstract: With the increased use of pipelines for carrying gas, oil, water, and electrical cables, the response of the pipeline to soil movements in the vicinity of the pipeline needs to be understood. These movements may be due to adjacent earth works, landslides, thaw settlement of permafrost, frost heave or a variety of other causes. These soil movements set up stresses within the pipeline and, depending upon the magnitude of these stresses and the nature of the pipeline, may cause damage to or failure of the line. Several consequences may be associated with pipeline failure and include loss of life, damage to the environment, and economic costs. The stresses which are generated by the soil movements are dependent upon a number of parameters, which include the nature of the soil, the properties of the pipeline, and the geometry of the pipeline/soil/backfill system. -- The state-of-practice (SOP) for pipeline design for areas where soil may move relative to the pipeline involves discretizing the pipeline into elastic-plastic segments which are connected to sets of  springs/sliders which simulate the soil. As the springs replace the soil, their force-displacement characteristics should correspond to the actual soil response if a meaningful analysis is to be conducted. Much of the theory behind the interaction parameters used in the SOP are derived from theories developed for other geotechnical applications such as pile/soil or anchor plate/soil interaction; there is little or no verification of the mechanisms or the magnitude of forces which arise during pipeline displacement. This thesis presents a research program conducted to examine one aspect of pipeline/soil interaction; that of lateral pipeline/soil interaction. -- The objectives of the research program outlined in this thesis were to: (1) conduct physical model testing of lateral pipeline/soil interaction in cohesive soil to ascertain the effects of trench width, burial depth, interaction rate, backfill properties, and stress history of the soil on the interaction using the centrifuge technique to maintain similitude between model and full-scale; (2) determine the characteristics of normalized force-displacement curves or interaction factors so that they can be used generically; (3) assess the displacement patterns and failure mechanisms of the soil around a pipeline; and (4) generate conclusions and recommendations regarding current and proposed methods of analysing lateral pipeline/soil interaction through comparison with experimental results. -- This thesis demonstrates that: (1) the trench width had little or no effect on an undrained interaction; (2) the undrained load on a pipeline increased with increasing burial depth; and (3) the pipeline displacement rate (and thus drainage conditions) had a significant effect on the loads transferred to the pipeline by the soil (for this particular soil/backfill system). The pipeline displacement rate effect is significant because the current state-of-practice for cohesive media is based on an undrained interaction between the pipeline and the soil which can significantly underestimate the ultimate load transferred to the pipeline. Also, the displacements required to reach these ultimate loads are significantly underestimated in existing guidelines for the soil/backfill system considered. Results from existing and proposed analysis methods to predict pipeline/soil interaction curves are encouraging. -- The undrained force-displacement response could be reasonably predicted and ultimate loads can be predicted within ±20% using existing methods of analysis. Experimentally derived methods of undrained analysis provided reasonable fit to the experimental data; an average of within 10% of the ultimate lateral load might be expected. Other potential methods based on undrained anchor/soil and pile/soil interaction resulted in predictions of ultimate loads within 20% of those measured experimentally. Pile/soil interaction p-y curves were found to provide reasonable predictions to the experimental data. Bearing capacity solutions showed potential to bound the actual ultimate load. Passive earth pressure solutions were found to yield reasonable undrained prediction for cases where the pipeline was shallow (H/D<2). -- Predicted drained (c-Ф) ultimate loads on the pipelines were consistently underestimated using existing methods. Drained analysis methods from the experimental data could be expected to predict the force-displacement response of the experimental data to within ±20%. Drained anchor/soil interaction analysis methods underestimated the experimental data. Drained pile/soil interaction methods provided reasonable fits to the data in cases. Cohesionless soil p-y curves were found to overestimate the actual experimental force-displacement response. Cohesionless soil bearing capacity solutions were found to overestimate while passive earth pressure solutions tended to underestimate the ultimate lateral loads.

title: Antioxidant potential of beans

abstract: Four different bean varieties with different coat colours (red, brown, black and white) were dehulled and the antioxidant compounds in the hulls and whole seeds extracted separately with 80 % acetone. The total phenolic content of the red, brown and black were higher than that of white beans both in the hull and in the whole seed extracts. Total phenolic contents of red and brown hulls were 2.3 times higher than those of whole seeds while that of the hulls of black beans were 7 times higher than black bean whole extract. Total antioxidant capacity of the extracts was evaluated using Trolox equivalent antioxidative capacity (TEAC) assay, β-carotene-linoleate and bulk stripped corn oil model systems. Extracts were used at 50 and 100 ppm phenolics as catechin equivalents. Scavenging efficacies of the whole bean extracts for reactive oxygen species (ROS) were evaluated using hydrogen peroxide, superoxide and 2,2-diphenyl-l-picrylhydrazyl (DPPH) radicals. Furthermore, inhibition of DNA-supercoiled strand scission and prevention of human low density lipoprotein (hLDL) oxidation by the extracts were evaluated. TEAC values of red whole bean extract (RWE), brown whole bean extract (BWE) and black whole bean extract (LWE) were 8.84, 7.46 and 4.64 while those of red bean hull extract (RHE), brown bean hull extract (BHE) and black bean hull extract (LHE) were 46.68 42.90, and 40.74, respectively. TEAC assay revealed that the antioxidant capacity of red, brown, and black bean hulls were in the same order of magnitude with little variation. Retention of β-carotene in a β-carotene-linoleate model system in the presence of RWE, BWE and LWE after 2 h of the assay was 46, 45, and 28% at 50 ppm and 52, 51, and 33% at 100 ppm, respectively, as compared to 2% in the control devoid of any extract. In a bulk corn oil model system, the order of efficacies of the extracts and reference antioxidants as measured by the formation of conjugated dienes (CD) was catechin > BHA > RWE = BWE = LWE > α-tocopherol. Inhibition of formation of hexanal in corn oil after 7 days was catechin > RWE = BWE = BHA > LWE > α-tocopherol. The efficacy of RWE, BWE and LWE at 100 ppm in scavenging hydrogen peroxide was 76, 73 and 65%, respectively. The corresponding values for superoxide radical scavenging were 54, 53 and 60%. Red, brown and black whole and hull seed extracts showed total scavenging of DPPH radical when used at 100 ppm. The Fe²+ chelation capacities of RWE, BWE and LWE were 58, 56 and 39% at 50 ppm and 72, 69, and 60% at 100 ppm, respectively. Red, brown and black whole seed extracts exhibited total inhibition of hLDL oxidation when used at 25 and 50 ppm. Red, brown and black whole seed extracts exerted total protection against peroxyl-induced DNA scission at 50 and 100 ppm levels while they did not show any protection towards hydroxyl radical induced-DNA scission. HPLC analyses revealed the presence of cyanidin in LHE while RHE and BHE contained both cyanidin and delphinidin. White bean hull extracts did not contain any of the two anthocyanidins. Ferulic, caffeic, sinapic, ρ-coumaric and vanillic acids were identified as major phenolic acids in bean hull extracts.

abstract: The Labourers' International Union of North America (LIUNA) approached The Western Centre for Continuing Studies (WCCS) of The University of Western Ontario (UWO) in March 2000 to develop and deliver an educational programme to promote the development of new models for joint relationships between labour and management. -- The rapidly changing marketplace, fuelled by the emergence of a global economy, has had a dramatic impact on the current industrial landscape. It appears that the economic  forces of change in Ontario, coupled with recently introduced government legislation, are influencing some sectors of labour and management to re-assess the nature of their relationship, and to find ways of operating more co-operatively together. LIUNA is a union that has embraced this challenge, and is taking a leadership role in developing and implementing new models for joint relationships (O'Sullivan. 2001). -- WCCS worked with LIUNA over the past year to develop an educational programme that will facilitate the development of new models of joint co-operation. The programme will bring together teams of labour and management in a joint learning process to facilitate interest-based planning, decision-making and problem-solving. The programme was developed in consultation with an advisory committee, made up of representatives of both labour and management. -- The programme has been designed and developed to provide participants with the know ledge and skills to relate the historical advances made by the labour movement to the emerging need to change again: to develop and apply the skill set required to engage in joint interest-based relationships: and to consider labour and management interests in a global context. The programme is unique and innovative, in that it will focus on joint training between labour and management. -- This paper outlines and describes the process of working with LIUNA to develop a programme to meet the needs they had articulated. The project commenced in March 2000 and it is anticipated that the first offering of the programme will take place in October, 2001. Personal learning objectives -- The development of new and innovative programmes to meet emerging needs identified within the workplace is an important component of the mandate for all university continuing education departments. Generally these new programmes are related to or drawn from areas of expertise within the larger institution, and are designed to share the benefits of the academic knowledge and body of research within the institution with the wider community. -- The request by LIUNA to work with them to develop and deliver a program for the development of joint models of co-operation provided an unusual and unique opportunity to research into a new area. While The University of Western Ontario is highly respected as an international leader in the field of management and business education and research, the field of labour relations is not studied or researched in any depth at Western. The opportunity to work with a large international union provided a challenge to explore another aspect of management education, and to identify and call on resources not readily available at Western. In addition, labour relations is an area not previously addressed within the portfolio of The Western Centre for Continuing Studies: the development of a successful program in this area could lead to the emergence of new opportunities and markets for WCCS. -- Personal learning objectives for this project included: -- • To improve personal knowledge and understanding of the field of labour relations -- • To research into the field of labour relations, and identify new approaches to promote co-operation, rather than confrontation -- • To work closely with a union to improve understanding of the mandate, mission, vision and values of organised labour -- • To explore the potential for developing a new area of expertise and research for The University of Western Ontario -- • To improve personal skills and expertise in the area of programme development.

Masters thesis, Memorial University of Newfoundland.

abstract: The purpose of this ethnographic study was to elicit data from nurse educators in Newfoundland concerning their knowledge of instructional development and to determine how nurse educators in Newfoundland plan instruction.  The study was a continuation of previous studies carried out in the school system in Newfoundland.  Gallant (1989), Tobin (1989), Thomey (1991), and Graham (1991) studied primary and elementary teachers, high school teachers, and teacher-librarians and determined that the groups studied did not have a comprehensive knowledge of and competency in instructional development. -- This study was executed from the winter of 1993 to the summer of 1993 using semi-structured interviews.  All interviews permitted open  responses and the interviews were respondent-driven.  The respondents consisted of one nurse educator from each of the five provincial schools of nursing. -- Results of the study indicated that the nurse educators who participated in the study have a functional knowledge of instructional development.  They plan instruction systematically.

abstract: The behavior of the geometry optimization of a large set of molecules has been examined. Particular failures and difficulties are noted for some systems and are shown to correspond to certain conditions. In cyclic systems, difficulties which can arise from using Z-matrix coordinates, which necessarily leave one or more bonds undefined, can be eliminated by using natural internal coordinates. The construction and definition of natural internal coordinates is extended to weakly bound systems, and possible definitions for fused polycyclic ring assemblies are discussed. -- 5-Substituted cyclopentadienes were chosen for their relevance to studies of facial selectivity in the Diels-Alder reaction. The central atom of the substituents chosen were of p-block elements, with any remaining valences filled with hydrogen. Basis set effects on the structures were examined, as well as the role of conformation on the various geometric parameters. The relative stabilities of the various conformers and the changes in geometry upon change in conformation are predictable from hyperconjugation arguments. -- The symmetric transition state of the degenerate substituent migration in 5-substituted cyclopentadienes has been studied. The activation barrier to migration was shown to correlate well with a dimensionless 'stretching' parameter. -- Several metal-aquo complexes were studied, including Li⁺, Be²⁺, Mg²⁺, A1³⁺, Sc³⁺, Zn²⁺, Ga³⁺, Cd²⁺, and In³⁺. For Li(H₂O)₅⁺, the character of stationary points can change with different basis sets. The vibrational frequency of the symmetric M-O stretching mode is always underestimated with extended basis sets, but can be improved by explicit inclusion of a second solvation sphere. -- The bimolecular complexes HF...HF, HF...H₂O, HF...NH₃, HF...CO, HF...NN, HF...NCH, and H₂O...H₂O have been studied. A rough correlation exists between the inverse of the hydrogen-bond distance and the bond strength. For HF complexes, the HF bond lengthens in accordance with the strength of the intermolecular interaction. -- The valence tautomerism between benzene oxide and oxepin has been studied. The enthalpies and barriers to tautomerization were very sensitive to basis set and method of correlation. The inversion barriers of the oxepin forms are reported. The effect of simultaneous methyl substitution at the 2 and 7 positions, of protonation, and of the replacement of oxygen with sulfur is examined. Some corrections to photoelectron band assignments are pointed out. The anti selectivity in the Diels-Alder reaction of benzene oxide is determined by a steric effect. -- Several 5,6-disubstituted 1,3-cyclohexadienes were studied. The potential surfaces of monocyclic structures were very basis set dependent, with minima disappearing and reappearing as one progressed to higher levels. A full comparison between experimental and theoretical structural and vibrational properties is made for 1,3-cyclohexadiene. The effect of conformation on the structure of cis-3,5-cyclohexadiene-1,2-diol is studied. The predicted photoelectron spectra are compared with experiment and assignments are made. -- The Z-matrix optimizations involved in the above studies were examined carefully. For 1,3-cyclopentadienes, some optimization problems could be traced to linearization of atoms involved in a bending coordinate, which rendered a corresponding torsion undefined. The transition state of the substituent shift in 1,3-cyclopentadienes, can be found by minimization in the totally symmetric subspace. The optimization of these species took more function evaluations on average than the corresponding reactant. Indications of the inability of Davidon's Optimally Conditioned method to deal with nearly converged structures may be a problem with either the method itself or the quality of the Hessian. For metal-aquo complexes, the symmetry of the species can be used to simplify the search for minima and/or transition states. In many cases, there are no totally symmetric modes corresponding to water librations, in which case the optimization proceeds smoothly. Bimolecular complexes gave optimization problems when symmetry could not be used to remove coordinates corresponding to the relative orientation of the molecules. For the valence tautomerisations, the monocyclic species optimized more quickly than the bicyclic species. The use of linear angles, and the resulting nearly singular Hessian gave problems. Poor Hessian updates for transition state optimization resulted in several failures which were corrected by resetting the Hessian. Many problems are related to both the coordinate system and the poor Hessian guess used for high amplitude modes. Proper internal coordinates in general speed up the optimization.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Aspects of the biology and taxonomy of the Coregonus autumnalis species complex were investigated in this study. The taxonomic and zoogeographic relationship of Coregonus autumnalis and C. laurettae was examined using morphometric, meristic, and distribution data.  The morphometric data, a series of head and body  measurements, was analyzed using a discriminant function analysis. The percentage of fish misclassified in the analysis was found to be higher than what would be expected for two distinct species, and was more indicative of subspecies, or stocks.  The only meristic variable found to be significantly different was gill raker counts for the lower branch of the first gill arch.  This character was originally used to separate the two species. An examination of the distribution of gill raker counts between the sample sites along the Beaufort Sea coast revealed a consistent percentage of the fish from the Mackenzie River with gill raker counts representative of the Yukon River species.  This percentage was maintained in the hypothesized area of sympatry between the two  species.  It was concluded, from this analysis, that the original description was incorrect in the establishment of two reproductively isolated species with a single area of sympatry, based on gill raker counts.  The actual situation is more likely that of two allopatric subspecies, with no area of sympatry.  The distribution data were also analyzed to determine the support for the original zoogeographic hypothesis proposed to explain the separation of the two forms.  It was concluded that the Bering Land Bridge was probably not responsible for this, as the present-day distribution of the two populations does not reflect ranges that could have been fragmented by the uplifting of the land bridge.   An alternative hypothesis, which better fits the current distribution patterns of each form, involves known stream captures and headwater transfers between the Mackenzie and Yukon Rivers.  Insufficient information is presently  available to determine the direction of the transfer, or through which river system the transfer was made. -- Life histories were investigated at a number of levels. Arctic and Bering cisco populations were investigated using one-way analysis of variance and multiple analysis of covariance.  No significant differences were found within the populations for reproductive variables but the two populations differed significantly from each other.  It was concluded that, based on the occurrence of alternate spawning and its relatively short life span, Arctic cisco populations appeared unable to compensate reproductively for the rigorous conditions encountered in northern latitudes. Least cisco (C. sardinella) populations were investigated at the same levels.  Between latitude comparisons were made using Mackenzie and Yukon River populations.  As with Arctic ciscoes, no significant differences were found within populations for reproductive variables, but significant differences were seen in between population comparisons.  It was concluded that northern least ciscoes, by virtue of their longer lifespan, are better able to compensate reproductively for the poor conditions encountered in the north than Arctic ciscoes.  A second analysis of a number of least cisco populations inhabiting the same latitude found that anadromous populations were larger and more fecund. However, analysis of covariance detected no significant difference in fecundity between populations.  An analysis of gonad weight among sympatric coregonines along the Beaufort Sea coast was conducted using an analysis of covariance but again, no significant difference was detected. A principal components analysis was used to determine patterns of life history variation in members of the subfamily Coregoninae using populations from North America and Eurasia.  The effects of both phylogeny and latitude were examined.  No significant trends in life history traits associated with latitude were found, although the subgenus Coreaonus (coregonus) did show a non-significant increase in egg size and number of broods with latitude, the subgenus Coregonus (leucichthys) showed non-significant inverse relationship for these variables and the genus Prosopium showed a nonsignificant inverse relationship for age and growth related variables.  A number of genera and species appeared to be constrained by phylogeny and were unable to adapt completely to the environmental constraints imposed by northern environments.  It was concluded that, despite this apparent inability to adapt, the great deal of variability of life histories demonstrated a large degree of plasticity in the subfamily.

Masters thesis, Memorial University of Newfoundland.

abstract: The major purpose of this study was to determine if participation in educational decision-making affected teacher productivity and teacher satisfaction. The data collection took place in April and May, 1976, using a six part questionnaire. Twenty-five high schools were randomly selected along the east coast of Newfoundland. This represented a total teacher sample of three hundred and fifty-eight. In all, two hundred and eighty, or 78.2 percent, responded. -- The data analyses consisted of factor analyses and Pearson product-moment correlations. The two hypotheses tested were: -- 1. There is an inverse relationship between friction point rating (FPR) identified by teachers and their Job Satisfaction. -- 2. An inverse relationship exists between friction point rating (FPR) and Teacher Productivity. -- The results of the bivariate analyses were negative; therefore, both hypotheses were rejected. However, the study revealed four major findings. They may be summarized as follows: (1) Three friction point areas emerged: classroom management, curriculum, and staff hiring and evaluation. (2) A teacher’s effort is significantly related to his intrinsic commitment to teaching. (3) There was a significant relationship between the friction point rating in the area of curriculum and a person’s satisfaction. Finally, (4) there was a significant relationship between a person’s self concept of his teaching ability and the friction point area classroom management.

abstract: A wide body of scholarly research reports that teachers consistently choose from a narrow repertoire of strategies in their teaching. This study attempted to broaden teacher repertoire directly, assessing teacher and student response to a new teaching method, role-play, while monitoring its implementation. Role-play was chosen as a suitable model because it is student-centered, has a history of educational use and is rarely encountered in science curricula. The investigation covered the full range of curriculum development, using a case study approach. A series of pilot studies in five classes over six months led to a curriculum package which was used in seventeen classes. This package consisted of a thirty-page role-play scenario with role briefs for student use plus guidelines and background for the teacher. The role-play concerns a town council debate over a proposed mine in an ecologically sensitive area. It requires two class periods. The material is suitable as a science-technology-society exercise for any secondary science class. Teachers attended a two-hour workshop about the teaching method. A total of fourteen teachers used the final package with four hundred and seventy-eight students. These classes were all at the Grade Seven level, in rural and urban schools.  Students completed questionnaires before and after the role-play.  The questionnaires assessed their attitudes to science and science teaching methods through Likert type and open-ended questions. Student responses to the Likert items were tabulated and examined for correlations with teacher responses. No significant differences were found among the classes.  Student responses demonstrated clear and consistent attitudes about their science classes. This included a dislike of seatwork and teacher talk and a strong liking for field trips and laboratory work.  Student responses on the open-ended questions were categorized.  Representative comments were chosen to illustrate the range of student feelings about their science classes and their reactions to the role-play. The comments support the positions indicated by the Likert responses. In addition, they reveal deep student support for their active participation in the classroom.  The role-plays were videotaped and analyzed using a rating scale. The rating scale had an interrater reliability of eighty-eight per cent. Teacher implementation of the role-play model, as might be expected for a first effort, varied over the wide range of twenty to eighty per cent. The study showed the feasibility of using role-playing classes in Junior High Science and the role-play's influence on affective learning of a large group of students. An important secondary finding was that teachers showed a wide range of implementation of the teaching technique. All teachers and ninety-six per cent of students expressed strong support of the exercise.

abstract: This study investigated whether students constructed understanding while engaged in electronic dialogue using WebCT computer conferencing software. The postings of graduate education students participating in the computer conference as a mandatory component of their university course were analyzed in order for me to make this determination. Transcripts from the entire computer conference constituted the major source of data for this research: these were printed at the end of the course and analyzed for indication of knowledge construction. -- Qualitative research methods were employed in this investigation. Information collected from a review of constructivist literature was utilized to devise an analytical model of socio-cognitive constructivist behaviors for deductively analyzing computer conference transcripts. The computer conference exchanges were also analyzed inductively whereby patterns of socio-cognitive constructivist behaviors emerged from them. -- Questionnaires were administered to participants in order to obtain a sense of their computer background as well as their Impression of learning via electronic dialogue. The questionnaires consisted of both pre-structured and open-ended questions. Responses to the questionnaire were utilized as a means of verifying the researcher's Interpretation of the results. -- It was concluded that knowledge was constructed by participants in this study as participants were seen to exhibit numerous forms of socio-cognitive constructivist behaviors.  Although It was initially believed that knowledge construction would result from participants debating conflicting viewpoints, socio-cognitive constructivist behaviors observed in this investigation resulted from participants sharing and co-elaborating ideas online.

abstract: Plants often react to various kinds of stress by changes in their organic composition as the result of defense or stress induced metabolism. This project investigated lichens as stress monitors, searching for changes in their chemistry under various environmental conditions. Qualitative analysis was carried out using Pyrolysis-Gas-Chromatography-Mass-Spectrometry following a micro-scale acetone extraction of dried and ground lichen samples. Only the newest growth of lichen was used. Semiquantitative analysis was carried out using Pyrolysis-Gas-Chromatography with a Flame Ionization Detector. -- Cladina mitis and Cladina rangiferina exposed to conditions of visible and/or ultraviolet light were received from Ontario. Bryoria trichodes and Usnea dasypoga were collected from sites of various ozone levels in New Brunswick.  Alectoria sarmentosa was collected from sites of varying sulfur dioxide exposure in Newfoundland. Changes in the unique lichen phenolics and fatty acids were detected. Results suggest that unsaturated fatty acids may be useful indicators of ultraviolet, ozone and possibly sulfur dioxide stress. It seems some lichen phenolics such as salazinic acid, alectoronic acid and alectosarmentin, as well as possibly usnic acid and atranorin, may be used to detect these stresses and may be involved in defensive biochemical responses. Future work should focus on verifying which of these changes are specific to a given stress.

Masters thesis, Memorial University of Newfoundland.

abstract: Background: University students are vulnerable to contracting HIV/AIDS because some of their behaviours are known HIV risk factors. Because HIV/AIDS is preventable, it is important to understand the factors associated with risk behaviours. Sex role attitudes, communication and assertiveness, and power balance in relationships are associated with safer sex behaviour. -- Hypotheses: 1. Respondents who hold more traditional thoughts about the rights and roles of women are less likely to practice safer sex behaviour. 2. Respondents who are not assertive about HIV and do not communicate effectively about HIV/AIDS and sexuality are less likely to practice safer sex. 3. Respondents who are in an unbalanced relationship with respect to power distribution are less likely to practice safer sex. -- Methods: The study was descriptive in nature. A 69-item questionnaire was administered to a convenience sample of 86 second- year university students enrolled in an undergraduate psychology course. The questionnaire consisted of sections on the roles of men and women, communication and assertiveness, safer sex behaviour, power balance, and demographics. Descriptive statistics, Pearson's correlation, test of equality of means and a multiple regression were used in the data analysis. -- Results: Traditional thoughts about the roles of men and women were negatively correlated with safer sex behaviour as was hypothesized. Assertiveness and communication was positively correlated with safer sex behaviour as was hypothesized. Power balance was negatively correlated with safer sex behaviour. Assertiveness and communication were found to be the most important statistical contributors to safer sex behaviour. -- Conclusions: Assertiveness and sexual stereotypes play an important role in one's ability to practice safer sex behaviour. Assertiveness training and training geared towards eliminating sexual stereotypes may give young people the awareness and confidence to protect themselves from HIV/AIDS. Power balance may also play a role in the prevention of HIV/AIDS but it is less evident in this sample.

Masters thesis, Memorial University of Newfoundland.

abstract: This report describes an 11-week internship at Eugene Vaters Academy and Junior High located in St. John's. During the internship, I engaged in many professional activities which enabled me to enhance and build on my skills as a counsellor. These activities included: individual counselling, group counselling, participating in case conferences, completing a variety of comprehensive assessments, participating in two inservices, administering developmental classroom guidance programs in personal safety and conflict resolution, and participating in school transition team meetings. -- I also had an opportunity to implement and deliver a Peer Helping Training Program at Eugene Vaters Junior High and to conduct research on the effectiveness of this training. In particular, the research was conducted to determine whether the training was effective in increasing the basic counselling skills of the participants. -- The results of this research study show that all participants demonstrated post-training gains in listening ability, empathic responding, empathic listening, and paraphrasing.

abstract: This thesis presents an improved control strategy to ameliorate the load voltage and supply current profiles in a power system. A synchronous d-q-0 based control scheme is developed for a hybrid series compensator topology to cancel the zero, negative and harmonic components from the load voltage and also suppress the supply current harmonics. -- The proposed d-q-0 based control scheme combines the decoupling of the current and voltage variables, transformation and filtering to extract the harmonic voltages and currents. In the harmonic current extraction procedure, the zero sequence components (including the fundamental frequency) are removed before applying the required transformations to filter out the harmonics from the supply current. This is done to ensure that the zero sequence components do not produce alternating components in the synchronous frame, which lead to errors in the filtered output. This control approach was developed as an improvement over the instantaneous active and reactive power (IRP) theory based scheme, which assumes a balanced and sinusoidal supply voltage. It is shown that the IRP theory based harmonic extraction procedure does not provide an accurate estimate of the supply current harmonics in the presence of imbalance, voltage distortion and zero sequence components. -- The feed-forward control approach based on the synchronous transformations in the d-q-0 frame is susceptible to gain variations which affect both system stability and the compensation error. Hence, a simplified single phase harmonic equivalent model is developed to carry out stability and distortion analysis of the hybrid series compensator topology. The effect of the controller gain parameters Ky and Rh on the stability limits is investigated with some root-locus plots. The influence of the controller gain parameters on the distortion levels in the load voltage and supply current is examined through a distortion analysis. From the analysis it is shown that limited controller gain margin is one of the drawbacks of the hybrid single-series compensator topology. Moreover, stability constraints on the values of the control parameters limit the range of compensation for wide variations in the supply voltage and load harmonics. -- A two-compensator topology is proposed to reduce the interaction between the voltage and current signals by allowing independent control of the two voltage components, thereby increasing the stability limits. A much larger controller gain margin (hence larger compensation range) and suppression of voltage drop across the passive shunt filter are shown to be some of the advantages of the proposed topology. -- A simulation model of the overall system with the proposed two-compensator topology is constructed using the SIMULINK toolboxes in MATLAB. The simulation results are used to demonstrate the effectiveness of the proposed d-q-0 based control scheme and the two-compensator topology when applied to load voltage compensation and harmonic isolation of non-linear loads.

abstract: The aim of this research was to functionally assess changes in cortical 5-hydroxytryptamine₂A (5-HT ₂A) receptors following exposure to drugs used to treat depression or to electroconvulsive shock. The literature suggests a possible role for 5-HT₂A receptors in the onset and treatment of depression but, to date, no extensive functional assessment of cortical S-HT₂A receptors has been undertaken to determine how important a role this plays. -- N-methyl-D-aspartate (NMDA) depolarizes cortical neurons and this depolarization is enhanced by 5-HT acting at 5-HT₂A receptors. Using this facilitation as a measure of 5-HT₂A receptor activity the functionality of 5-HT₂A receptors on cortical neurons was assessed following acute and chronic exposure to imipramine, fluoxetine or mianserin. These results were compared with those following a course of electroconvulsive treatment (ECT). -- The results showed that following chronic (14 day), but not acute (2 day) exposure to imipramine and fluoxetine, the 5-HT concentration response relationship was shifted to the right and exhibited a lower maximum response compared to controls. In contrast, mianserin, a 5-HT₂A receptor antagonist which also exhibits antidepressant efficacy, produced a similar shift and reduced maximum following acute exposure. ECT did not alter the 5-HT concentration-response relationship. Neither drug exposure nor ECT significantly altered NMDA responses. -- Based on these results it is concluded that cortical 5-HT₂A receptor down-regulation may be an important event in mediating the therapeutic response achieved following chronically administered antidepressants. 5-HT₂A receptor down-regulation may shift the balance from excitatory 5-HT₂A receptors in favor of inhibitory 5-HT₂A receptors, co-localized on postsynaptic cortical neurons. Thus, a rise in synaptic 5-HT levels following chronic antidepressant treatment increases the activity of postsynaptic 5-HT₁A receptors and results in an increase in inhibitory 5-HT neurotransmission. A rise in inhibitory 5-HT neurotransmission could counteract the increase in excitatory 5-HT activity thought to occur in depressed individuals. This represents a return in net 5-HT activity to a homeostatic level, alleviating symptoms associated with depression.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: The object of the study was to describe the assemblage of epibiotic organisms associated with the shell of the sea scallop, Placopecten magellanicus (Gmelin, 1791). Qualitative information from approximately 3 dozen shells was combined with quantitative data obtained from 12 additional shells. The numerical data were subjected to statistical analyses in order to examine dominance, diversity and affinity within the association. -- Live scallops were collected by divers from an area in St. Mary's Bay, on the southeast coast of the Island of Newfoundland. The external surfaces of the shells were examined using a dissecting microscope and the area occupied by each epibiotic species was measured. X-radiography was used to investigate the effects of boring species within the shells. A total of 74 epibiotic species of animals and plants was recorded. -- The affinity studies revealed that the scallop shell supports an epibiotic community consisting of separate and distinct component communities on its upper and lower valves, each having a predictable species composition. No seasonal or depth-related effects were detected regarding the community on adult scallops over 10 years of age, but the structures of the associations on young scallops (2 and 3 years old) were different in several respects from the adult shell community. -- The dominant species are sessile or sedentary in habit and are either filter- or deposit- feeders. They are not obligate members of the community, but nevertheless reproduce and in some cases complete their entire life cycle within the community. Diversity indices obtained for the community were generally low (ranging from 0.3 to 3.6 for a single valve) and were lower for upper valves than for lower valves. -- Boring species play an important role in the development of the community. Their activities modify the surface of the shell, making it more habitable for certain later-arriving species. Damage to the shell is rarely extensive and the scallop does not generally appear to suffer any harm from the presence of these or any other of the epibionts.

Masters thesis, Memorial University of Newfoundland.

abstract: The hippocampus is important in spatial navigation in rodents. Less clear is the relationship between the cognitive map of physical space, and task requirements that take place within that space. This study addresses the issue by recording pyramidal cells of the hippocampal CA1 region as animals perform the Lawrence and Homel (1969) discrimination task. Proceeding from a start box, animals made a choice to run down either a black or white alley, which led to a grey delay box. Following a brief delay, animals entered the goal box to receive a reward for a correct alley choice. Although the goal box always occupied the same physical space, the colour varied with reward contingency in the experimental group. I hypothesized that animals would have two representations of the delay box, one based on anticipatory reward, and the other not. Results indicated that the animals had differential representations of the goal boxes, and that they viewed the delay box as a constant space.

abstract: The thesis reappraises the growth of Methodism in Newfoundland finding that it was a populist movement energized by the religious dynamic of a quest for spiritual ecstasy. This is in contrast to an historiography that has presented a top-down history of Methodism as a moral rescue by clergy of a degenerated populace encased in isolation and a cruel environment. That historiography has fixed upon the administrative formation of the Newfoundland District in 1815 and the consequent increase in clergy as the turning point in its history. -- Instead, Methodism was a lay spiritual movement of a people searching for ecstasy. It spread as a dynamic personal religion, facilitated by the migratory nature of its population. The most prominent characteristic of the residents was not isolation, but mobility, expediting the spread of Methodism as a religion of experience. Transhumance included both dual residency and further family movement to the northeast coast and Labrador for the summer fishery. There was also the vocational mobility of fishing voyages along the southeast coast and sealing voyages on the northeast coast. It was this lay zeal and mobility which were the primary means for the spread of Methodism in Newfoundland, not the organizational efforts of British missionaries. -- Populist Methodism in the bays of Newfoundland, continually energized through revivals, was in sharp contrast with the extremely hierarchical 19th-century versions of Anglicanism and Catholicism--Tractarianism and ultramontanism--emanating from St. John's. Methodism presented a vision of man, not in contrast to the cruel land, but in contrast to clerical mediation, through its proclamation of direct access to God. The vernacular religious impulse was trusted to such a degree that deference to clergy gave way to popular freedom and self-assurance. In this way Methodism, which grew to over a quarter of the population, gave a third dimension to Newfoundland society, the capability and acceptability of the vernacular.

abstract: This thesis is an examination of the life and work of a Newfoundland visual artist and the response of her audience. A native of Dresden, Germany, Elizabeth Margot Wall lived in Newfoundland for twenty-three years-from 1970 to 1993. She relocated to Fredericton, New Brunswick, in August 1993. Elizabeth Margot Wall has chosen for her subject matter the coastal communities of Newfoundland and Labrador. For the purpose of this study, she will be referred to as a Newfoundland visual artist. The thesis is an interpretation of the cultural grounding of a body of nonacademic artwork based in cultural theory. -- My experience as a native Newfoundlander informs the discussion as do the articles, books and newspapers I have read and the interviews I have conducted. In the process of its writing, I have learned that the natural beauty of this province not only dazzles me, but also enchants the visitor. This rich and sensuous environment, as depicted by Elizabeth Margot Wall's idealized landscapes, conveys a metaphysical concept which reaches out metaphorically to Newfoundlanders and non-Newfoundlanders alike in a constructive and emotional warmth. Its unique integrity enacts a transformative process that unleaches the creativity of its inhabitants and visitors, its artists and consumers, in an act of artistic communication. -- Ultimately, Elizabeth Margot Wall's paintings are objects of meaning, not only for the artist but also for viewers, buyers and interpreters. This thesis, therefore, is an exploration of the paintings' various levels of signification.
