abstract: The present study examined (1) the nature of sociometric choice and rejection patterns, and (2) the differences in adjustment of nontransported and transported pupils who have been brought together in centralized elementary school classrooms. More specifically: 1. An analysis of the sociometric data indicated to what extent nontransported and transported pupils chose friends from within and rejected members from outside their respective groups, and 2. An analysis of the adjustment data provided information on differences in the personal and social adjustment of transported and nontransported pupils. -- The sample used in this study consisted of 194 Grade IV, 169 Grade V, and 169 Grade VI pupils in elementary schools in three rural school districts. In the total sample there were 271 nontransported and 261 transported pupils. -- Data for the study was obtained from a specially developed sociometric test and from the standardized California Test of Personality (CTP). The criteria of the sociometric test permitted each pupil to name 5 classmates whom he would choose, and 5 classmates he would not choose, if he were moving to a new classroom. The California Test of Personality provided adjustment data for the following sub-tests: (a) self-reliance, (b) sense of personal worth, (c) feeling of belonging, (d) withdrawing tendencies, (e) social skills, (f) anti-social tendencies, and (g) school relations. -- A chi-square .analysis of the sociometric choice data was carried out separately for boys and girls. This meant four different groups in each grade: nontransported boys and girls, and transported boys and girls. The results of the analysis indicated that in nearly all of these groups, transported pupils chose transported pupils, and nontransported pupils chose nontransported pupils at frequencies significantly greater than those expected by chance. The only exceptions were Grade IV nontransported and transported boys - these two groups exhibited no biased tendency to choose members within their own nontransported and transported groups. -- A chi-square analysis of the sociometric rejection data was also carried out separately for boys and girls. This analysis did not suggest that nontransported and transported pupils were inclined to reject each other to any great extent. More specifically of 24 possible combinations only the five cases below were statistically significant: 1. Grade IV nontransported boys rejected transported girls; 2. Grade V nontransported boys rejected transported girls; 3. Grade V transported boys rejected nontransported boys; 4. Grade V nontransported girls rejected transported girls; and 5. Grade VI nontransported girls rejected transported boys. A disquieting factor here is that in four of the five cases, nontransported pupils rejected transported pupils, while the reverse occurred only once. In all the above cases, the significant probability level was P<.05. -- A two-way analysis of variance of the California Test of Personality scores resulted in only one significant difference between the mean scores of nontransported and transported pupils: in Grade IV the nontransported pupils scored significantly higher than transported pupils on the “feeling of belonging” component. All other CTP components extracted no differences between adjustments of nontransported and transported pupils. Also, division of the sample into (1) groups of high and low sociometric status, and (2) groups of boys and girls did not elicit any significant interactions between (1) the transportation treatment and sociometric status, and (2) the transportation treatment and sex. -- In view of the fact that the analysis of sociometric rejection data resulted in relatively few significant cases, the strong within-group choice data should probably not be viewed with alarm. Also, the lack of significant differences in personal and social adjustment of nontransported and transported pupils suggests no new administrative provisions for the incoming transported pupils.

Masters thesis, Memorial University of Newfoundland.

type: Thesis NonPeerReviewed

abstract: Sea scallop (Placopecten magellanicus) juveniles have been reared in a hatchery at the Ocean Sciences Centre, Memorial University of Newfoundland, for several years and transplanted to scallop farms located in three Newfoundland bays. This study was undertaken to investigate the effect of diet on growth of spat to help optimize hatchery production. Four experiments were performed to determine which available algal diet(s) resulted in greatest growth (in terms of shell height, dry weight and organic weight) of juvenile P. magellanicus ranging in size from 1-4 mm shell height. It was found that of the diets tested, a ternary mixed diet consisting of the three species Isochrysis galbana, Isochrysis aff. galbana (T-Iso) and chaetoceros spp. (muelleri or calcitrans), fed in a 1:1:1 ratio at a final concentration of 50 cells/μl, resulted in the greatest growth for juveniles sized 2-4 mm. A unialgal Isochrysis galbana diet supported as much growth as the ternary mixed diet in scallops sized 1-2 mm. The unialgal Chaetoceros diets did not support any appreciable growth. ALGAL 161, a commercially available, spray dried, heterotrophically grown Tetraselmis suecica product, was found to be a poor food for P. magellanicus juveniles. Gross growth efficiencies were determined for scallops for the different diets tested. No significant differences in growth efficiencies among the diets were found -- A short-term experiment was done to study the effect of ration on filtration and ingestion rates for three size classes of juvenile Placopecten magellanicus (2-4 mm, 4-6 mm, > 6 mm). It was foudn that as ration increased, filtration rates decreased and ingestion rates increased. Values for filtration and ingestion rates (F) were related to growth rate (W) using the general allometric equation F=aWb. The physiological rates were found to be increasing faster than the growth rates of these young juvenile scallops with values of the exponent (b) ranging from 1.47-2.24.

Masters thesis, Memorial University of Newfoundland.

abstract: The primary objective of this prospective questionnaire study was to determine whether self-reported symptoms were predictive of nerve conduction study (NCS) results. The population consisted of 211 unselected patients with clinically suspected carpal tunnel syndrome (CTS) who were physician referred for confirmatory NCS. These patients were administered a pre-NCS questionnaire. Patients reported 350 symptomatic hands, and 72 asymptomatic hands. A comparison of symptom lateralization and bilateral NCS results was performed. Standardized electrophysiologic criteria were applied. In symptomatic hands, 49.2% of NCS studies reported median mononeuropathy, while, 50.8% were negative. In asymptomatic hands, 37.5% of NCS studies showed median mononeuropathy, the remaining 62.5% were negative. Overall accuracy of NCS compared to symptoms was 51.4%, with a sensitivity of 86.4%, specificity of 20.1%, positive predictive value of 49.1% and negative predictive value of 62.5%. These comparisons do not support a strong relationship between clinical symptoms and NCS results in this patient group.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Wolf and brown bear populations are expanding throughout Europe, in a human dominated landscape. Conservation of these two species will be determined by the attitudes of those who live close to them. Unlike in North America, human dimensions (HD) regarding human-wildlife issues remains a relatively new field of research in Europe, and even more so in Italy. This is the first study of HD in wolf and bear management in Italy. -- This dissertation has focused on understanding how the attitudes of those living in close proximity to both wolves and bears can play a role in achieving conservation planning. -- Attitudes are positive of negative evaluations of an object - in this case wolves or bears - and are a mental state composed by affective (feelings), cognitive (beliefs) and behavioural intention components. Each component of attitude plays a role in the conservation of wolves and brown bears. The objectives of this study were to look in detail at these three components, how they can be linked, and how they contribute to conservation. Quantitative face-to-face (n=1611) interviews were carried out to determine attitudes of residents toward wolves and bears in the Abruzzo, Lazio, and Molise National Park (PNALM) and the surrounding buffer zone. -- This dissertation demonstrated that the majority of residents in the PNALM are willing to coexist with these large carnivores. Participants expressed positive feelings toward wolves and bears, they tolerated the perceived damages caused, and they support the maintenance and protection of both species - but especially of brown bears. This dissertation showed that residents have a higher level of knowledge about bears, which results in stronger positive feelings. -- These are important messages to communicate to managers responsible for the conservation of wolves and brown bears. Emphasizing these positive findings can be the staring point for constructive dialogue on conservation. This study, therefore, sets the direction for the future public involvement processes. The next HD step would be to organize workshops with all interest groups (e.g. shepherds, hunters, non-locals), to bring them together and to work with them on their commonalities to create a management plan for wolves and bears.

abstract: Reconfigurable systems have drawn increasing attention from both academic researchers and creators of commercial applications in the past few years because they could combine flexibility with efficiency. There are two main types of reconfigurable architectures - fine-grained and coarse-grained. The functionality of fine-grained architecture hardware is specified at the bit level while the functionality of the coarse-grained architecture hardware is specified at the word level. Coarse-grained reconfigurable architectures (CGRAs) have gained currency in recent years due to their abundant parallelism, high computational intensity and flexibility. A CGRA normally is comprised of an array of basic computational and storage resources, which are capable of processing a large volume of applications simultaneously. To exploit the inherent parallelism in the applications to enhance performance, CGRAs have been structured for accelerating computation intensive parts such as loops, that require large amounts of execution time. The loop body is essentially drawn onto the CGRA mesh, subject to modulo resource usage constraints. Much research has been done to exploit the potential parallelism of CGRAs to increase the performance of time-consuming loops. However, sparse  connectivity and distributed register files present difficult challenges to the scheduling phase of the CGRA compilation framework. While traditional schedulers do not take routability into consideration, software pipelining can improve the scheduling of instructions in loops by overlapping instructions from different iterations. Modulo scheduling is an approach for constructing software pipelines that focuses on minimizing the time between the initiations of iterations - the so-called initiation interval (II). For example, if a new iteration is started every II cycles, the time to complete n iterations will approach II x n, for large n loops, thereby maximizing performance. -- The problems of scheduling (deciding when an operation should happen), placing (deciding where an operation should happen), and routing (the problem of how information travels through space and time between operations) can be unified if they are modelled by a graph embedding problem. The data flow graph of the loop is embedded in a routing resource graph representing the hardware across a number of cycles equal to the initiation interval. -- Particle swarm optimization (PSO) has shown to be successful in many applications in continuous optimization problems. In this thesis, we have proposed algorithms to solve scheduling, placing, and routing of loop operations simultaneously by using PSO. We call this approach modulo-constrained hybrid particle swarm optimization (MCHPSO). There are many constraints and one optimization objective, which is the II that needs to be considered during the mapping and scheduling procedure. The scheduling algorithm tries to minimize the initiation interval to start the next iteration of the loop under the resource and modulo constraints for the architecture being used. -- When conditional branches such as if-then-else statements are present in the loop, they create multiple execution paths. Exploiting conditional branches through our predicated exclusivity, the MCHPSO algorithm reuses the resources which are in the exclusive execution paths and which may allow the loop to be scheduled with a lower II. Finally, a priority scheme algorithm along with recurrence aware modulo scheduling is proposed to map inter-iteration dependencies onto CGRAs, which is able to save resources for all recurrences cycles and to map remaining operations.

abstract: Research suggests that reading disabilities result from phonological processing deficits. Penney’s (1989) separate-stream hypothesis suggests that phonological deficits in poor readers may be linked to defective auditory information processing and a deficient A (auditory) code in short-term memory. The study reported here tested the hypothesis that good and poor readers, at the university level, differ in their auditory short-term memory and auditory information processing capabilities. Subtests from the Woodcock-Johnson Psycho-Education Battery – Revised (Woodcock & Johnson, 1989) were used to measure reading and auditory processing skills. To test short-term memory recall, lists of four to nine digits were presented auditorily or visually. The usual modality effect was observed for the good readers with auditory presentation producing higher recall. In contrast, for the poor readers the modality effect was observed only for the last serial position; for the middle serial positions visual sequential recall was higher than auditory recall, producing a reverse modality effect. The results of the Woodcock-Johnson subtests indicated that the poor readers did have deficient auditory processing capabilities.

abstract: Variability is inherently an important characteristic of natural ecosystems. Like any other parameter that may define an organisms' environment, selection has favoured traits and strategies that exploit patterns in the variability of fluctuating physical and biological resources. Here I consider the ways in which animals may be affected by anthropogenic change that reduces variability in natural ecosystems. -- Through many anthropogenic activities, we have inadvertently introduced resource patches into the environment that are fixed in space and that provide animals with regular access to food through time. These predictable food patches have become ubiquitous, and represent a fundamental change for animals that have adapted to a relationship between variability and scale. I provide a theoretical framework through which we can begin to understand the consequences of breaking such a relationship for animals that use information to make foraging decisions. I conclude that predictable resource patches should be favoured by foraging animals because the energetic costs of obtaining information are reduced at these sites. -- I use the ideal free distribution (IFD) theory to test the hypothesis that animals will prefer to forage where resource distributions have become predictable. Given the choice between patches of equal value but that differed in the temporal predictability of their food, juvenile cod gradually developed a preference for the predictable patch over a 5-day experimental period. This preference occurred simultaneously with a reduction in patch sampling behaviour, suggesting that cod were able to reduce the costs of obtaining information at the predictable patch. -- Having observed that the distribution of cod shifted towards the predictable patch in an experimental setting, I examine the effects of introducing a predictable resource patch into a natural environment. Aquaculture sea cages are fixed in space and inadvertently provide stable access to resources to wild animals through time. I consider the effect of sea cages on the distribution of wild fish in coastal marine environments, in which patterns of fluctuating resources are distinguished by a large magnitude of variability. I demonstrate that sea cages can alter the distribution of marine life at large spatial scales, suggesting that there is an energetic advantage to foraging at these sites. Understanding the costs and benefits of this behaviour is needed to predict the outcome of anthropogenic changes that alter patterns of variability in natural ecosystems.

abstract: In 1926 Newfoundland enacted legislation to restrict immigration in spite of the fact that the island had received very few immigrants in the previous seventy years. The antecedents of the 1926 Immigration Act can be found in the colony's own immigration experience, the shift in international immigration policies after the First World War, and its relations with Canada and the United States. -- After the First World War, Canada and the United States effectively restricted immigration to Mainland North America. This shift in immigration policy left Newfoundland with the most liberal regulations in North America and caused increasing difficulties for the colony's migrating labour force. Unlike its neighbours, Newfoundland did not experience mass immigration in the early part of the twentieth century. As a result, immigration policy was not a high priority. The colony did not have in place the administrative or legislative framework to respond to the development of international or North American restrictions. -- Canadian and American immigration officials pressured the Newfoundland Government to restrict immigration in the wake of two organized immigrant smuggling schemes in 1925-26. The arrival of two small groups of eastern Europeans in St. John's enroute to the United States, and the subsequent investigations launched by the American consulate and local investigations launched by the American consulate and local officials, warned legislators that the colony could be the recipient of redirected immigrants. With an uncertain economy and a dependence on the goodwill of its neighbours to relieve its excess labour, Newfoundland reacted to concerns over immigrant smuggling by passing a new immigration act in 1926. -- This act emulated Canadian style restrictions and ended a tradition stemming from 1906 of judging prospective immigrants, with the exception of the Chinese, by individual merit. This was significant as individual merit was replaced by blanket restrictions as a way of screening potential immigrants. The 1926 Newfoundland Immigration Act was the last stage in a trend to create uniform immigration standards for North America after the war.

abstract: ²H NMR studies of synthetic polypeptides in bilayer membranes were performed. The results suggest that such transmembrane polypeptides undergo fast, axially symmetric reorientation about the bilayer normal and have a preferred average azimuthal orientation about the helix axis. Quadrupolar splittings and quadrupolar echo decay measurements indicate that the correlation time for reorientation is on the order of 10⁻⁷s. At high temperatures the spectra are indicative of peptides that rotate mainly as monomers while broadening at lower temperatures is consistent with transient peptide-peptide interactions. The appearance of a broad, low amplitude feature in spectra at low concentrations seems to indicate that a certain fraction of peptides interact and rotate as short lived dimers. -- Further ²H NMR studies of two synthetic polypeptides with glycophorin A (GPA) motifs suggest that these model peptides are tilted in bilayers and rapidly reorient about the bilayer normal with a correlation time on the order of 10⁻⁷s. Observed spectra and echo decay measurements indicate that the orientation and dynamics of each peptide depend on GPA motif position. This suggests that the position of the interaction motif in the peptide sequence may play an important role in determining peptide orientation in bilayers. -- To characterize helix motion and orientation, systems consisting of 64 molecules of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) and one a-helical polypeptide with the sequence acetyl-KK-(LA)₁₁-KK-amide were examined by molecular dynamics simulation. The systems were allowed to evolve for up to 10 ns at 1 atmosphere of pressure and a temperature of 55°C. It is was found that the polypeptide orders lipid chains and thus increases bilayer thickness in accordance with previous simulations and experimental observations. Alanine methyl groups were found to be inequivalent which is consistent with ²H NMR splittings observed from specifically labelled polypeptides in POPC bilayers. The simulation results suggest that the polypeptide assumes a preferred orientation with respect to the bilayer normal and about the molecular long axis.

abstract: The cutting forces, tooth wear, surface finish, and cutting power were observed for 3/8" x 3" side and face milling cutters at two levels of cutting feed (2.1 and 7.7 in./min.) and depth of cut (.005" and .010") while cutting Inconel X-750. -- The investigation briefly traces the development of metal cutting science, pointing out some of the fallacies which have persisted to the present day. It proposes that metal to metal contact, and hence wear, be reduced by using a soft metal as a solid lubricant. Copper was eventually selected because of its electro-negative nature when compared to high speed steel. Copper is deposited continuously on the face and flank of milling cutter teeth by an electrolyte solution of copper sulphate and sulphuric acid. -- The experiment consisted of three phases, the first being of a preliminary nature to evaluate the feasibility of depositing copper by this process. Measurements of cutting power for various depths of cut, using a mild steel work piece, were compared to those obtained using a soluble oil, with favourable results for the copper sulphate electrolyte. -- Evaluation of the electrolyte cutting fluid to determine its optimum composition by measuring cutter wear, cutting forces, cutting power, and the surface finish of the work piece, follows. Observations of surface finish and cutting power produced no positive result. However, the other variables indicated a preference for a copper sulphate concentration of 11.1 grams per litre of solution and a sulphuric acid concentration of 5 millilitres of concentrated acid per litre of solution. -- The determination of the optimum composition of the copper based electrolyte was achieved using Inconel X-750 as the work piece material. This grade of Inconel was also used in the third and final phase of the experiment, which was to compare the electrolyte cutting fluid with a conventional sulphurized cutting oil. Results of this comparison indicate that the conventional cutting oil, Veedol AFTON #8 containing 1.8 to 2 per cent sulphur, produces less wear at a lower wear rate than the copper sulphate solution.

Masters thesis, Memorial University of Newfoundland.

abstract: Predation risk is a driving force in the distribution of juvenile fish. In coastal Newfoundland, age-0 Atlantic cod (Gadus morhua) use the protective cover of eelgrass (Zostera marina) in preference to exposed, sandy areas. Studies suggest that habitat configuration is closely correlated to the population dynamics of certain species. A relationship between eelgrass patch morphology and predation risk of cod could allow for indirect assessment of natural predation based primarily on eelgrass configuration - a variable more easily quantified than natural predation itself. In three experiments, I used a tethering technique in Newman Sound, Bonavista Bay, Newfoundland, Canada, to quantify the relative predation risk of post-settled age-0 cod in natural eelgrass habitats. I examined the influence of eelgrass patch size (1-80m²) on predation risk based on the assumption that larger patch size results in lower predation compared to small patches. I also tested for the presence of edge effects at an 18 m long, vertical boundary between a mud and an eelgrass habitat. Lastly, I evaluated the effect of patch shape on predation by quantifying the fractal exponent of individual patches. I conclude that predation was correlated to patch area and proximity to patch edge, but not to the shape of individual patches.

Masters thesis, Memorial University of Newfoundland.

abstract: The functional diversity of marine bacteria from the sediment-water interface of Newfoundland coastal waters was characterized by examining carbon source utilization. Although some benthic strains utilized a broad range of substrates, many were considered fastidious. Bacteria with a strictly respiratory metabolism predominated at the sediment water interface. Upon initial isolation, approximately 50% of the colonies observed on the plating medium, at 15°C, were pigmented. Most studies do not report a significant proportion of pigmented bacteria occurring in the marine environment. The proportion of pigmented bacteria was much lower if the plates were incubated at 5°C. The recovery of bacteria was higher at 15°C, than at 5°C, therefore the population studied was psychrotrophic rather than psychrophilic. Eighty percent of the strains isolated required Na for growth, indicating that the population studied was mostly of marine origin. The Biolog-GN assay showed that strains were more metabolically active in September than in June. There was no functional difference in the substrates utilized by strains at each sampling date, isolation temperature, or between groups of pigmented and non-pigmented bacteria. Sixty-six percent of all cultured strains utilized glucose and 62% utilized glutamic acid. These were among the most widely utilized substrates on the Biolog microplate. They may, therefore, be the most appropriate choices as substrates for studies of heterotrophic potential as long as the percentage of the population actually metabolizing them is considered. Approximately 38% of the strains, subdivided as 17% of the pigmented strains and 54% of the non-pigmented strains, utilized thymidine and 20% utilized leucine.  These compounds can be used to estimate bacterial growth rates assuming that they are incorporated directly into DNA or proteins, respectively. If the bacteria metabolize these compounds as substrates their use in estimating microbial growth rates could result in an underestimation of the true microbial production occurring in this region, especially if non-pigmented bacteria are abundant. Based on the results of Biolog substrate utilization patterns there were significant differences between the regional strains and most of the reference cultures with the reference strains being more metabolically active and utilizing a broader range of substrates.

abstract: I studied behaviour of Harlequin Ducks (Histrionicus histrionicus) at Fig River (53° 03' N, 63° 09' W) and Crooked River (54° 06', 60° 48' W) in Labrador in spring and summer of 1999 to 2002. Observations indicated that paired adults devoted modest proportions of time (30 to 40%) to foraging. This, and the lack of variation in time budgeted to feeding across time and space, indicated that Harlequin Ducks were not limited by food on their breeding habitat in Labrador. -- Most pair bonds dissolved by early June indicating nest initiation by the females. All adult females that were examined following capture and/or followed by radio signal appeared to be reproductively active. Low annual productivity on the study areas appeared to be due to predation of nests, and I concluded that Harlequin Ducks breeding in Labrador may be limited by predators. -- Noise is a significant stressor for animals, and the non-auditory effects of noise are considered whole body stress responses. In addition to overt responses, behavioural effects of noise on adult Harlequin Ducks were subtle and protracted. I interpreted this as evidence that a larger 'whole body' or physiological response was occurring. Animals challenged repeatedly develop high circulating levels of stress hormones in the bloodstream that can ultimately lower survival and inclusive fitness. -- Alert responses by adult Harlequin Ducks in central Labrador occurred to noise (75- 120 dBA) generated from low-level (30- 100m agl) military jet over-flights. Alert (startle) was generally <1% of time budgets, and increased in a dose-response manner, accelerating above a threshold of approximately 80 dBA. Protracted effects included increased inactivity, and decreased time out of water. There was evidence of residual effects of increased agonistic behaviours up to 1 h and decreased courtship up to 1.5 h following over-flights by military jets. The protracted and residual effects have the potential to negatively affect time-activity budgets of individuals. Multivariate statistical analyses demonstrated the importance of considering behaviour holistically because the inclusive modeling of covariance among behaviours was superior to traditional univariate approaches. Important effects may easily be overlooked because of bias by researchers in defining 'behavioural responses' a priori (e.g. Startle or Alert) that are easily observed because effects can be subtle and protracted well beyond the actual disturbance.

abstract: In Canada there has been a long history of concern within political and educational arenas for the status of culture-based programs in elementary, secondary, and postsecondary school curriculums. It is within this historical context that this study found its purpose and significance. This study, proceeding from an extensive base of information provided by the Crawford (1971) and Robinson (1979) reports, had as its major purpose an analysis of the contents of the senior high school English programs authorized for use in the Atlantic provinces during 1981-82. The problem set for the study was the determining of the extent to which these programs contained materials that reflect a local, regional, or national Canadian culture. -- The investigator examined, analyzed, and rated 389 of the 406 different textbooks authorized by the Atlantic provinces' departments of education for use in their respective senior high school English programs. From the investigation emerged the following nine findings: -- 1. Of the 406 authorized textbooks only six were common to all four Atlantic provinces. These were: Julius Caesar and Twelfth Night; The Old Man and the Sea, The Pearl, Lord of the Flies, and Who Has Seen the Wind. Only one of these six books was culture-based - Who Has Seen the Wind. -- 2. Common to any combination of three Atlantic provinces were but 23 senior high school English textbooks. Within that number were four Canadian works: the novels The Mountain and the Valley, More Joy in Heaven, and Who Has Seen the Wind, and the play "The Black Bonspiel of Willie MacCrirnrnon" by W.O. Mitchell. -- 3. In the Atlantic region, in 1981-82, Canadian owned publishers supplied 34% of the provincially authorized textbooks for the senior high school English programs. The province with the highest percentage of Canadian published texts was Nova Scotia with 39%; the province with the lowest, 24%, was Prince Edward Island. -- 4. Approximately 128 out of the 389 books examined, or 33%, revealed a recognizable Canadian content. Again Nova Scotia and Prince Edward Island ranked highest and lowest. Of the textbooks examined from Nova Scotia's senior high English program, 50.70% of them reflected a recognizable Canadian orientation, while, concurrently, only 17.82% of Prince Edward Island's could be so identified. -- 5. Of the 389 textbooks examined, 92 contained 60% or greater Canadian content, while 199 of them, or approximately 51%, had less than 20% Canadian content. -- 6. a) Within the Atlantic region as a unit, Short Stories and Language Study areas of the curriculum were those most heavily weighted with Canadian materials. -- b) Most conspicuous in the absence of culture-based materials was the area of Teacher and Classroom References in Prince Edward Island where of the 35 authorized texts not one had any Canadian orientation or content. Another statistical highlight was that of only 10% of the drama in New Brunswick's senior high English program being Canadian drama. -- 7. Some local materials were present in all the Atlantic provinces' senior high English programs. Newfoundland had the highest number of local materials with 7, while Prince Edward Island had the lowest number with 1. -- 8. In 1981-82 two Atlantic provinces offered courses in Canadian literature, those being Nova Scotia and New Brunswick. Newfoundland plans to introduce a course into its re-organized high school curriculum sometime after 1982-83. -- 9. Three of the Atlantic  departments of education had no written textbook selection policy that stated a preference for materials published in Canada. -- From these findings the author concluded that the departments of education in the Atlantic region, if they intend to increase significantly and expeditiously the number of culture-based materials in their senior high school English programs, must undertake some affirmative action. Upon that premise the author tendered to those departments a number of recommendations. -- The Atlantic provinces' departments of education should: -- 1. develop written textbook selection policies that state a preference for learning materials that are Canadian authored and published with clear Canadian orientation and as much Canadian content as appropriate and desirable; -- 2. establish an Atlantic provinces' organization that would plan, co-ordinate, and support the production of local materials; -- 3. subsidize the Canadian Learning Materials Centre in Nova Scotia so it can expand its operations to build a resource reference collection of culture-based learning materials, provide display services, provide a research and evaluation service, and offer inservice programs to teachers on the availability and utilization of culture-based learning materials; -- 4. introduce greater commonality into the senior high English curriculums in Atlantic Canada; -- 5. pressure the Canadian Council of Ministers of Education, Canada, to provide financial assistance to Canadian authors, editors, and educational organizations for the production of culture-based learning materials.

abstract: In this thesis I demonstrate that Kant's notion of freedom remains consistent throughout his practical philosophy. By examining Kant's notion of Wille in the Metaphysics of Morals, we see that finite rational agents can choose against the moral law. Some Kant scholars, when interpreting Kant's early moral philosophy, omit the possibility that finite rational agents can freely choose against the moral law. Instead, they maintain that the only options available to finite rational beings are to act in accordance with the moral law, which is a free act, or act based on empirical incentives, which is a determined act. Through introducing the practical example of suicide, I show that this interpretation logically excludes certain acts, as well as removes any notion of moral responsibility from Kant's practical philosophy. However, through an examination of An Answer to the Question: What is Enlightenment?, the Groundwork of the Metaphysics of Morals, and the Critique of Practical Reason, I follow such commentators as Henry Allison in showing that Kant clearly maintains that finite rational agents can freely choose to act against the moral law and thus are responsible for all of their actions including their immoral acts.

abstract: Statement of the Problem -- Although Canadian provinces have had international dealings since Confederation, these activities have apparently intensified since the 1960's and provoked renewed interest among both politicians and academics. -- In an effort to understand the reasons for this renewed provincial activity and to evaluate its possible effects on federal and provincial spheres of jurisdiction, the emergent literature attempts to identify specific cases of transnational relations and develop typologies of interaction. -- This study attempts to add to the data base of provincial international activity by examining Newfoundland's activity in this area between 1960 and 1978. -- Materials and Methods -- Oral materials consisted of interviews of the administrative heads of Newfoundland provincial government departments or their representatives as well as provincial politicians. The interviews were conducted in 1978-79. Written sources included government documents, legislative debates, books, scholarly articles, newspapers and miscellaneous unpublished materials. -- The major assumptions to be tested are that the international activity of the province of Newfoundland is not atypical of the activity of other Canadian provinces, and that interest and involvement in international activity on the part of the province is a function of the perceived importance of specific issues and policy areas, rather than a desire to generally assert a provincial competence in external relations. Interviews were therefore conducted with governmental respondents with a view toward collecting data of recent provincial external activities and of eliciting attitudes toward the provincial role in Canada's foreign relations. -- The procedure was inductive. Initially, all pertinent materials were gathered. Subsequently the data was classified into distinct categories for analysis and generalization. -- Conclusions -- The nature of provincial international activity largely relates to functional administrative matters, but even these may raise broader national and international legal issues. -- Newfoundland, as a provincial actor in international relations, conducts itself on a level comparable with other provinces though on a much smaller scale. There is no indication that the province's international activity is anything other than a process pursued for the fulfillment of immediate and long term functional needs. There is no evidence to warrant the conclusion that the attainment of an international presence or status is a policy of the Newfoundland government. Indeed, in most cases, the activity is not even perceived as being international. -- Research in this area has to date focused on relations between provinces and American states. The findings of this study indicate that Newfoundland is somewhat more active than other provinces in international contacts with states other than the United States. One possible explanation for this tendency may be found in Newfoundland's history but definitive conclusions must await further research.

abstract: Strontium-90 activities in milk, rainwater and tapwater samples, collected in St. John's, Newfoundland, have been determined in the present investigation. Milk samples were collected weekly over two periods: January, 1961 to January, 1962 and July, 1962 to August, 1962. Rainwater and tapwater over the period Hay, 1962 to July, 1962 were studied. It was found that the strontium-90 levels in milk increased from a low of 2.4 to a high of 21.1 micromicrocuries per gram calcium over the experimental period. The activities in tapwater have also shown an increase from 0.25 micromicrocuries per litre in April, 1961 to 2.1 micromicrocuries per litre in July, 1962. Strontium-89 activities in rainwater and tapwater samples have also been computed. -- During the course of the investigation a Philips low-level beta counter was calibrated with a standard strontium-90 source.

Masters thesis, Memorial University of Newfoundland.

abstract:
In the Province of Newfoundland and Labrador, the evolution of Fish Trades Associations and their Union counterparts has been greatly impacted by the historic relationship between the processing sector and the harvesting sector. Processors, or merchants as they were traditionally referred to, have gone through a cycle over the past 60 years or more from holding tremendous power over fishers through what was known as the truck system, to today's environment characterized by legislation aimed at protecting the independence of fishers. -- The fishing industry has also undergone widespread change since the late 1940s when saltfish was king and the frozen fish sector was in its infancy. Since then the frozen industry has become the dominant sector. Until the early 1990s cod was the primary species, but since the decline of cod stocks throughout the 1980s and early 1990s and the resulting closure of the Northern cod fishery, shellfish had become the dominant sector. Trade unions have become a significant factor affecting all aspects of the conduct of the fishery from price issues with buyers to international issues such as the Northwest Atlantic Fisheries Organization (NAFO) stock regulations and foreign overfishing. Processor associations on the other hand have seen their position of power erode beginning with the collapse of Newfoundland Associated Fish Exporters Limited (NAFEL) and its exclusive right to market saltfish, to the Fisheries Association of Newfoundland and Labrador's (FANL) inability to gain accreditation as the sole bargaining agent for all processors in the Province. -- There are many notable milestones in the evolution of processor and harvester organizations. Included in these milestones are the formation of the first fishermen's benevolent organization, the Society of United Fishermen (SUF) in 1873, the formation of the Fishermen's Protective Union in 1908, the formation of the Frozen Fish Trades Association (FFTA) in 1944, the formation of the UFFA WU, the predecessor to today's FFA W, and introduction of the Fishing Industry Collective Bargaining Act in 1971 as a means of governing the collective bargaining between the harvesting and processing sectors. There have also been other significant events that
have influenced the development of the fishery and have also impacted on both the harvesting and processing sectors in a significant way. These events include Newfoundland joining Canada in 1949 and the resulting change in jurisdiction over the harvesting sector away from Newfoundland to Ottawa. Following the change in jurisdiction came the introduction of fishermen's Unemployment Insurance to the Province. Other significant policies have evolved including the Federal government's Fleet Separation Policy which prevents processors from controlling licences for vessels under 65' LOA. -- Although groundfish stocks have collapsed and no recovery is in sight, the value of the fishery is now higher than it has ever been in the past. Today's fishery has evolved into one that is dominated by shellfish, primarily snow crab and shrimp. These species have yielded significantly greater economic benefits to participants and have afforded the harvesting sector the opportunity to significantly increase its power base within the industry. While many fishers remain at the low end of the economic ladder, fishers with access to crab and shrimp are generally better off than they have ever been. In fact, many of these fishers have developed their businesses into multi-million dollar enterprises. -- The collective bargaining system in which raw material prices are determined has serious flaws which place processors at a serious disadvantage to fishers. Fishers remain independent and have the ability to sell their product to those local firms who offer the highest price. While this has always been the system, problems in the crab and shrimp sectors associated with it have been masked by increased quotas since the moratorium on cod was announced in 1992. While the number of processing licences has increased 3-fold since then, so has the resource base. However, we are now seeing significant reductions in the abundance of crab and processors have been pitted against one another as they compete for sufficient raw material to maintain businesses in which they have invested so heavily. -- The most immediate issue facing the processing sector is the high cost of raw material generated by the increased competition. Fishers are now able to demand unprecedented prices from processors who are competing with long-established processing companies, as well as new entrants to the fishery for sufficient raw material to viably operate their plants. Plants are unable to vertically integrate their businesses by buying harvesting licences. The Fleet Separation Policy which was introduced by the Federal Government in 1976 prevents processing companies from owning licences for inshore vessels, except those which were "grandfathered" when the policy was implemented. -- As with any system that favours or appears to favour one group or another, pressure gradually mounts for change and the political opportunity to make the change. Perhaps it is time for change to the fishing industry collective bargaining system and to Federal and Provincial fishery regulations. Many of the regulations currently in place are aimed at protecting the independence of fishers from large processing companies, but it appears that processing companies may be in jeopardy by the ineffectiveness of these rules and regulations. History has played a large part in shaping the current regulatory regime, but perhaps the system has outlived its usefulness. However, given Newfoundland and Labrador's continued reliance on the fishery for the survival of many rural communities and the lack of prospects for employment generation in other industries, it is recognized that change won't come easily. -- The future role in collective bargaining of Fish Trades Associations such as FANL, which represents the majority of the processing capacity in the Province, continues to evolve. FANL continues to push for accreditation and the right to negotiate a maximum price for raw material for the entire industry. Until processors and fishers can negotiate on an equal footing the collective bargaining process currently in place will continue to generate problems for both sectors. While the industry continues to experience serious problems relating to raw material price and distribution, it is difficult to see a future role for FANL that does not involve collective bargaining. Negotiating raw material prices for the thousands of fishers and the plants they sell to will remain an important task. It remains to be seen what changes are implemented to the collective bargaining system and the timing of these changes to make the system less  problematic for the industry as a whole.

abstract: The ability to remotely sense ocean winds has numerous research and commercial applications. High Frequency radar operating in ground wave mode has proven itself to be an effective means of remotely sensing the ocean surface. This is because at the typical operating frequencies (3-30 MHz), the radar signal can travel very large distances. Also, wavelengths in this band interact closely with the most energetic ocean waves. The problem that is dealt with in this thesis is the extraction of the wind speed blowing over a radar-illuminated patch of ocean. -- The Doppler spectra of the returned radar signal contain a wealth of oceanographic information. This is owing to the various complex electromagnetic scattering mechanisms. The radar cross section of the ocean surface that results has many salient features that can be used to extract particular ocean parameters. Based on the existing HF radar theory, an expression is derived that extracts the peak frequency of the ocean spectrum from the radar cross section. This spectral peak frequency is then linked to oceanographic models which dictate the growth of an ocean spectrum to a given wind condition. -- The models are applied to simulated noisy data. In addition, appropriate signal processing techniques are applied to mitigate the effects of noise and to improve the robustness of the models. Finally, the models are applied to sample HF radar data provided by Rutger's University. This data was obtained from a Coastal Ocean Dynamics Applications Radar (CODAR) operating in Breezy Point, NY. The results are then compared to ground truth data provided by the National Oceanic and Atmospheric Administration (NOAA) from a weather station located in the vicinity of the illuminated patch of ocean.

abstract: Objectives and Methods: This study compared Return-for-service (RFS) programs available from provincial/territorial governments, determined terms of interest and predictors of acceptance in Newfoundland and Labrador (NL), and described experiences of RFS-holders. Research methods included document analysis, an online survey, and telephone interviews. -- Results: RFS programs were a poplar means of improving physician distribution. -- Students rated monetary value (37.3%) and location of service return (34.9%) as the most important features in their decision to accept an RFS. Trainees with financial concerns and those who planned to remain in NL were 4.8 and 27.7 times more likely to accept a bursary. -- Experiences of RFS-holders were positive; communication difficulties and a lack of active recruitment were identified as problems. -- Conclusions: The RFS shows some promise for increasing physician recruitment, however it does not appear to be the most effective means; more bursaries fund trainees who plan to remain in NL already (80%) than attracts novel trainees (20%).

Masters thesis, Memorial University of Newfoundland.

abstract: Boreal forests, like all forests, are affected by disturbances. Whether natural or anthropogenic, disturbances have the ability to influence forest processes and alter existing conditions, eventually affecting the overall forest composition and distribution. Each type of disturbance, as well as each specific event, is unique in terms of its characteristics and its effects. -- The overall objective of this study was to look at whether or not the disturbance history of boreal forests in Terra Nova National Park, Newfoundland was reflected in the water chemistry. One component of the study examined the long-term effects of fire and logging on water chemistry of park lakes, as well as the short-term effects of a forest fire in one area of the park. The second component of the study examined a specific forested watershed and how a local disturbance, moose herbivory, was affecting soil solution chemistry. -- Overall, it appeared that with moderate disturbance and given sufficient time, forests are able to recover naturally and minimize any long-term chemical effects to their environment. Results from the short-term study of a recent forest fire did suggest chemical differences in soil solution. However, the local disturbance of moose herbivory showed no discernible effects in the short-term. Effects of this disturbance likely require a longer time to become apparent.

abstract: The Liberal campaign for self-government in Newfoundland made great headway in the early 1850’s only after the Roman Catholic Church undertook to campaign in its behalf. While that alliance, in a Colony almost evenly divided between Catholics and Protestants, ensured a strong base of support for the Liberals at the same time official Catholic opposition to the government tended to confine the reform movement to a sectarian cause. Past experience had demonstrated that the partnership with the conservative “Church of Rome” had proven damaging to Liberalism while the Catholic Bishop had proven unable to restrain his lust for domination thereby tending to alienate Protestants from the Liberal Party. When the latter, therefore, earnestly began the fight for Responsible Government after 1850 the Conservatives resisted the movement as a Catholic plot to gain ascendancy and attempted to organize Protestants in an effort to depict the reform campaign as a purely religious struggle. Limited success, however, was accomplished in this regard as religious dissentions split the Protestant community from within while the presence of more tolerant and compromising leadership, both within the Catholic Church and the Liberal Party, made it possible for the latter to take advantage of Protestant disunity and acquire non-Roman Catholic support. Thus the liberals were able to broaden their denominational appeal and win Responsible Government in 1855. -- However, the assumption of power by the Liberals became, in a sense, the means to their downfall as their dependence on Roman Catholics was clearly underlined by the denominational character of their political appointments. While this tended to hasten ‘Protestant Union’ at the same time the conflicts which had theretofore divided the Protestant community became resolved. In addition, rivalries among Protestant denominations became replaced by dissensions within Catholic Liberal ranks as the more liberal, independent Catholics opposed the ascendancy of the Bishop supported, conservative, Irish Catholics. When the Roman Catholic Bishop, therefore, attempted to mold a party more completely subject to his views independent Catholics revolted and rejected his interference. While the Liberal Party officially supported Bishop Mullock in an attempt to unite Catholics by a religious campaign the Conservatives took advantage of the resulting disunion to draw off Protestant support and bring the down fall of the Liberals in 1861.

Masters thesis, Memorial University of Newfoundland.

abstract: This study was an attempt to explore aspects of the development of communication strategy (CS) use in the interlanguage (IL) of young second language (L₂) learners. The investigation examined the frequency and patterns of CS use by successful language learners (SLLs) and by less successful language learners (LLLs) at two points in time, in an attempt to document inter-group and intra-group patterns of change over developmental time. The eight subjects of the study were students in an Early French Immersion (EFI) Program in an urban Newfoundland school and data was collected at the end of the Grade Two Year (Time 1) and again at the end of the Grade Five Year (Time 2). The subjects provided taped speech samples by means of picture description elicitation tasks at both times. -- The speech samples were transcribed and analyzed for CS use, using a typology of CS based on those developed by a number of second language (L₂) researchers. The information obtained through the analysis was converted into table format, showing individual and group strategy use at Time 1 and Time 2. -- As well as a quantitative description of CS use, a qualitative description was undertaken. The results of the study indicated that both groups of subjects showed evidence of variation over time in the frequency of use of particular strategies and in the percentage of use of these strategies. Over time, most subjects decreased their use of reduction strategies, cooperative strategies and retrieval strategies and increased their use of L₁-based (interlingual) and L₂-based (intralingual) strategies. -- The analysis also indicated that the pattern of use of categories and subcategories CSs changed over time for both groups. Both groups used more achievement strategies and fewer reduction strategies at Time 2 than at Time 1. The LLLs dramatically increased their use of L₂ –based strategies, indicating that change was in the direction of the target language (French). The SLLs, however, showed a much slighter increase in their use of L₂-based strategies. -- Analysis of the surface realization or quality of strategies used at Time 1 and Time 2 did not indicate any clear-cut differences between the two groups of subjects, nor between Time 1 and Time 2 strategies. Both groups did, however, use more qualitatively superior strategies (intralingual strategies) at Time 2 than at Time 1, but for the SLLs the degree of change over time was less than for the LLLs.

abstract: This thesis deals with the family photography collection, an aspect of visual and verbal folklore which allows families to record their activities, to communicate within the family and with outsiders, and to entertain themselves and others. This threefold function is exemplified, as is the form of the family photograph collection, primarily in a detailed study of the collections of two St. John's, Newfoundland families, the Kellys and the Cousens. These are used to illustrate the concept of roles in the creation and use of family photograph collections: the photographer, who records the events, the subject, who allows himself to be recorded, the archivist, who organizes the results, the interpreter, who describes them, and the audience, who observes them. The Kelly and Cousens collections are also the source of most specific examples of photographs and associated narratives. An historical depth is established for family photograph collections and it is related to their present form and function. The continuity seen with earlier forms of photography, family portraiture and photographic display is explained by the flexibility allowed by the roles; that different individuals may take them, that responsibility for them can be divided in the family, and that each individual may weigh his role according to his interests. The connection between family photograph collection roles and individual personalities, as well as the collection's general importance to family life, are seen.

abstract: The primary objective of this doctoral research was to examine the impact of acute care reform and its implications for health system and provider outcomes in Newfoundland and Labrador, Canada. A second objective was to identify the best predictor models of, health care provider outcomes (organizational commitment, intent to/ stay, and health care quality) at different phases of the reform process. Registered nurses, the largest group of employees in the acute care sector, were selected as the exemplar for model testing. -- This doctoral research was comprised of three empirical studies, each of which led to manuscripts for publication. The first study was an examination of the perceptions of system reform on health care providers (registered nurses, licensed practical nurses, physicians, allied health professionals, management personnel) conducted between 1999 and 2000. The second empirical study was are-survey of health care providers between 2001 and 2002. In the third study in 2005, the focus was on documenting registered nurses' changes in perceptions of health care reform and attitudes from previous years and monitoring consistency of predictors of final outcome (perceived health care quality, organizational commitment, intent to stay). Collectively, the three studies and the resulting five manuscripts constitute a thesis that forms the basis for an ongoing and future program of research for monitoring perceptions and attitudes over time and the consistency of predictors of outcome for all health care providers. -- The findings indicate that restructuring had a negative impact on health care providers' perceptions of the emotional climate, practice issues, collaborative relations, trust in employer, job satisfaction, organizational commitment, intent to stay and health care quality that was observed at all time periods. Key aspects of organizational culture emerged as significant predictors of intermediate (trust in employer and general job satisfaction) and final outcome for registered nurses. Health care provider perceptions of, the organizational culture and reactions to organizational change may, also have important implications for their health status, job performance, productivity and sick leave usage, as well as ultimately for organizational outcomes such as service quality, efficiency and costs. -- This research based evidence has major health policy implications for three levels: macro (governments), meso (regional health boards, senior leadership and managers of institutions, public) and micro (individual health care providers, professional bodies/unions). Innovative strategies to promote and enhance organizational culture (emotional climate, collaborative relations, and practice issues) may ultimately lead to higher levels of job satisfaction, trust in employer and organizational commitment, greater intent to stay, and more positive perceptions of health care quality.

abstract: A technique has been developed for obtaining single crystals of molecular crystals in solid phases which can be reached only from other solid phases. The technique was used to produce large (≈50 mm³) single crystals of CH₄ -I and CD₄-I in a liquid helium cryostat cell, which then were successfully cooled down below the phase transition temperatures. The crystals were studied by the means of Raman and Brillouin spectroscopies. X-ray Laüe diffraction techniques were applied to determine the orientation of the crystals in the laboratory frame. The elastic constants of CH₄-I, II and CD₄-I, II and III were determined as a function of temperature from 90 K to 15 K. The possible space groups of CD₄-III were determined on the basis of Brillouin data. -- Bulk adiabatic moduli and shear moduli were calculated from the elastic constants as functions of temperature. The elastic constants were used to calculate the acoustic velocities in high symmetry planes, and also the Debye temperature which is in agreement with previous results. The rotational specific heat of each species was calculated as a function of temperature. -- Raman spectra of the fundamental modes ν₁ and ν₃ were recorded and their shifts and full width at half height were determined as functions of temperature through the phase transition.

Masters thesis, Memorial University of Newfoundland.

abstract: Surgery patients constitute a large percentage of in-house hospital patients. While once customary, admitting elective surgical patients' one to two days before surgery is no longer an accepted practice. With pressure increasing to contain health care costs, hospital stays are becoming shorter. As health care dollars decrease and shortages of surgical beds increase, most hospitals are looking for ways to improve their efficiency with decreasing resources. As a result, same day admission for many procedures is rapidly becoming a commonplace hospital cost containment program. In such programs, patients undergoing elective surgery receive preoperative testing, preparation, and education on an outpatient basis. Patients are admitted to hospital on the day of surgery. St. Clare's Mercy Hospital, in St. John's, Newfoundland, Canada, introduced its pre-admission clinic in November 1993. The Same Day Admission program now consists of two components: the pre-admission clinic visit and the same day admission service. This study endeavoured to determine the effectiveness and the effects of a cost containment strategy on the quality of patient care of the Same Day Admission program, at St. Clare's Mercy Hospital. The objective of the study was to detect any problems in the process and quality of patient care and to make recommendations for continuous improvement. "Plan-Do-Check-Act" (PDCA) Cycle (Walton, 1986) was the conceptual framework used to focus the research. The research questions were placed in the "Check" phase of the PDCA Cycle. Conclusions were drawn about the efficiency, the effectiveness, and the quality of patient care for this program through a review of a) patient outcomes and clinical indicators, and b) patient and healthcare provider satisfaction with the program. The population for the patient interviews was patients who were prepared for surgery in the Pre-Admission Clinic (PAC) and admitted to hospital on the day of surgery during the first six months of the program. The population for the healthcare provider focus groups and interviews was physicians who referred patients to the Same Day Admission program and a stratified sample of other healthcare providers who provided services to these patients.  Information obtained from the patient and healthcare provider focus groups, patient and physician interviews, and a review of clinical indicators allowed the researcher to answer the following research questions: -- 1. Do the program outcomes indicate patient satisfaction with the process? -- 2. Do the program outcomes indicate healthcare provider satisfaction with the process? -- 3. Do patient clinical indicators indicate quality health care? -- 4. Do decreased length of hospital stay and low re-admission rates support the program as a cost containment program? -- 5. Do the program outcomes indicate attainment of program objectives? -- The analysis of the data was presented according to the research questions of this study. Patients' interview statements were examined and displayed through frequency and relative frequency distributions. The overall degree of patient satisfaction was very high at 90.73 %. The interview and focus group data were analyzed, according to the healthcare subgroup, using procedures outlined by Zemke and Kramlinger (1985). Most of the physicians' statements were very positive. They perceived the Same Day Admission program as being very positive for patients. Patients were accessing the necessary services, consultations were being organized, and patients were being educated about their entire surgical experience. Healthcare providers had both positive and negative perceptions of the care being provided to these patients. Their perceptions of the advantages of the program included the following: early identification of patients with discharge needs; patients were more educated as to what would be happening to them before, during, and after their surgical procedures; patients were more prepared for their surgery and their return to the community; services needed for patients' discharges were being identified before admissions to hospital; with decreasing lengths of hospital stay, more patients were accessing the services; improvement in patients' satisfaction; and improved access to preoperative consultations. Healthcare providers were also concerned with the assessment criteria for referring patients to the Pre-Admission and Same Day Admission program versus inpatient admissions. Nurses and therapists also voiced concerns with the incompleteness or absence of information for preoperative and postoperative patient assessment and care. Physicians did identify areas needing amelioration. These areas were: 1) dedicated medical resources for patient assessment and completing the History and Physical in the clinic; 2) internist and anaesthetist schedules to include Pre-admission consultations; and 3) increased resources (human and financial) to continue the work of the program. The objectives of the program focused on improved bed utilization, improved patient satisfaction, and enhanced quality patient care. These objectives were to be achieved through early identification of preoperative medical problems, initiation of early discharge planning, and provision of patient and family education Among the recommendations made was consideration be given to establishing an appropriate forum to address healthcare providers' concerns with the incompleteness or absence of information needed for preoperative and postoperative patient assessment and care. The researcher also recommended the Pre-Admission Committee establish protocols or assessment criteria for determining appropriateness of referring patients to the Pre-Admission and Same Day Admission program versus inpatient admissions. Consideration should also be given to further studying the length of hospital stays for same day admission patients and comparable Case Mix Groups of inpatients.

abstract: This thesis investigates how women who quilt in St. John's, Newfoundland construct and negotiate gendered and middle-class practices. I explore the ways quilters frame complex 'selves' and ideals of womanhood by analyzing their dialogues, performances and interactions. This analysis focuses on themes that emerged from my ethnographic fieldwork such as 'personhoods', 'femininity', 'community', 'middle-classness' , 'power', 'agency' and 'social action'. I analyze how some quilters 'piece' narratives of communication within their creations for the purpose of expressing personal agency. I also include an investigation of the contexts where quilters choose to mobilize personal agency into social action through quilting. This thesis is grounded in the historical context of quilt creators in twentieth century Newfoundland and Labrador where the practice of quilting has developed into an ambiguous act. 'Ibis ambiguity provides quilters a negotiable site to reveal, through narrative and 'performance', values and ideals that construct their individual and collective womanhoods.

abstract: I-Benzylpyrrole was prepared and subjected to bromination, nitration and formylation and the products isolated and identified. l-Benzyl-3-bromopyrrole was converted to l-benzyl-3-pyrrolecarboxylic acid and to methyl l-benzyl-3-pyrrolecarboxylate; l-benzyl-3-nitropyrrole was converted to l-benzyl-3-acetamidopyrrole. I-Benzyl-3-pyrrolecarboxaldehyde was oxidized to the 3-acid and l-benzyl-2-pyrrolecarboxaldehyde was converted to the nitrile and thus to the 2-acid and the acid esterified to its methyl ester. -- Identification of the compounds has been accomplished primarily by interpretation of nuclear magnetic resonance spectra in conjunction with infrared spectra and elemental analysis. Some interconversions of the derivatives were also successfully performed. Further evidence for the assigned structures of the 2- and 3-esters has been furnished by the synthesis of these compounds by unequivocal routes. -- The catalytic reductive debenzylation of methyl I-benzyl-3-pyrrolecarboxylate was attempted, but with no success. -- Attempts were made to prepare l-benzenesulfenylpyrrole and 1-(2,4-dinitrobenzenesulfenyl)-pyrrole but without success, the 2-substituted products being obtained in each case. The formylation of 1-(2,4-dinitrobenzenesulfenyl)-pyrrole gave only the 5-formyl derivative.

abstract:
Rationale: Cardiovascular disease (CDV) is the leading cause of mortality and morbidity in Canada. Mortality from cardiovascular disease is higher in Newfoundland and Labrador (NL) than other Canadian provinces. Gender differences in the treatment of and assessment of CVD have been repeatedly demonstrated in clinical trials. -- Objective: 1) To determine the existence and impact of gender bias in the treatment of Acute Myocardial Infarction (AMI) in NL. 2) To determine if male gender is associated with inappropriate use of surgical revascularization in NL. -- Design: Two observational studies: 1) Prospective cohort study; 2) Cohort study with retrospective data collection. -- Setting: University based tertiary referral center in St. John's, NL. -- Participants: 1) AMI patients admitted between May 24, 1990 and June 30, 1993 and followed for 3 years. -- 2) Patients referred for Coronary Angiography (CA) between April!, 1994 and March 31, 1995 who subsequently underwent Coronary Artery Bypass Grafting (CABO). -- Measurements: 1) The gender rates of risk factors, post-MI complications, CA, pharmacologic interventions, CABO, Percutaneous Transluminal Coronary Angioplasty (PTCA), functional class assessment using Goldman scales and mortality for three years following AMI were compared. -- 2) CAD risk factors, angina severity, coronary anatomy, medical therapy, CABO indication, appropriateness and necessity of CABO and operative risk and post operative complications were compared by gender. -- Results: 1) During the AMI admission 9.4% of women compared to 3.9% of men had recurrent MI (p=0.04), 12.6% of women and 7.4% of men died (p=0.03). With the exception of heparin (67% male vs. 58% female p = 0.02), pharmacologic intervention was comparable in men and women. CA was performed in 31 % of women and 41.9% of men (p = 0.007). Men were more likely to be revascularized during the AMI admission (19.3 vs. 12.2, p= 0.02) but there was no gender difference in revascularization up to three years post-MI. Multiple logistic regression analysis (MLR), which included
demographic and clinical characteristics, revealed that male sex was a strong predictor of CA and revascularization post-MI. During follow-up women consistently reported a statistically significant reduced functional capacity. Survival analysis revealed that women had significantly reduced likelihood of survival (p=0.004) independent of age and Angiotensin Converting Enzyme (ACE) inhibitor therapy. -- 2) Although there was no gender difference in angiographic findings of patients referred for CABG, 88.5% of women compared to 78.90,4, of men were referred for CA due to Class IV angina (p=0.006) and 49.9% of women versus 30.1% of men were at moderately to very high operative risk (p=0.000). CABO was deemed highly appropriate in 96.8% of women versus 99.5% of men (p=0.066) and highly necessary in 92.7% of women versus 94.2% of men (p=0.66).  -- Conclusions: 1) In Newfoundland and Labrador, Canada, despite more complicated post-MI courses, women were as likely as men to receive standard pharmacologic intervention but significantly less likely to undergo CA and revascularization following AMI. -- 2) Furthermore women referred for CABO had more advanced and severe CHD than men. It is possible that gender bias in the utilization of coronary revascularization may contribute to excess CHD mortality observed in women. -- Caution must be exercised in generalizing the results of these studies of highly selected populations to the overall population of NL.

abstract: This study examines the effect of temperature on the development of active swimming ability in the larvae of two cold-water fish species, the pelagic spawner Gadus morhua (Atlantic cod) and the bottom spawner Myoxocephalus scorpius (shorthorn sculpin). The first chapter provides a brief overview of studies on swim speed in larval fishes and how they have been used in studies of dispersal. The second chapter examines the development of critical swimming speed in larvae of the two species reared at different temperatures. These swimming tunnel experiments show that temperature has a clear effect on critical swimming ability of sculpin larvae as they increase in size and age. By contrast, a temperature effect on development of swimming ability in cod larvae was only observed with thermal summation age. Sculpin larvae hatched at a bigger size and stronger swim speed than cod larvae, and also exhibited faster development rate of swimming speed relative to both size and age than cod. The third chapter examines the influence of temperature on development of sustained swimming ability in larvae of the same two species. For sculpin larvae, temperature only has a significant effect on development of sustained swimming ability as a function of absolute age, although sustained swimming speed increased with both age and size. For cod larvae, however, there was a significant temperature effect on development of sustained swimming ability only as a function of size. Cod larval sustained swim speeds lagged behind those of sculpin larvae as a function of age because of the smaller size of cod larvae at hatch. The fourth chapter presents larval transport simulations for Placentia Bay, Newfoundland, in which larvae were initially assumed to be entirely passive and thereby transported exclusively by mean currents. These results were compared to simulations that combined larval active swimming speeds with the influence of mean currents. These simulations, which were conducted for spring and summer temperatures, were then compared to field patterns of larval concentrations from multiple biological surveys in Placentia Bay. The simulations indicated that larvae of bottom-spawning sculpin could take advantage of currents and their strong swimming ability to influence dispersal and improve retention within the embayment, particularly in warmer water temperatures. Larvae of pelagic-spawning cod were almost entirely passive, irrespective of water temperature. Field patterns of cod and sculpin larvae were generally consistent with the simulations, particularly in the context of the active retention simulation for sculpin. This thesis demonstrates that active swimming by larval fish has the potential to significantly influence transport and dispersal, but this potential differs for species and environmental conditions.

abstract: The objective of this thesis is to design and develop a numerical simulation tool for the class of unsteady free surface flows with arbitrarily moving rigid bodies. The major technical issue encountered in the solution of free surface problems is the appearance of numerical instabilities that arise due to the description of the mesh movement to track the moving boundaries, nonlinearity of the governing equations and boundary conditions implementation at the free surface and rigid body surface. -- In the present computational model, a fluid flow governed by the full Navier-Stokes equations is only modeled within a two-dimensional computational domain. The motion of the air is neglected and the effect of the ambient pressure exerted on the fluid by the air is taken into consideration. The method of solution is based on a finite volume discretization of the unsteady Navier-Stokes equations in their pressure-velocity formulation on a fixed Cartesian grid. A special integral form of the governing equations is derived by extending the Reynolds transport theorem and then applying it to control volumes containing a fluid interface for the first time. The combined volume of fluid and fractional area/volume obstacle representation method, and the cut cell method are employed to track the fluid-air and fluid-body interfaces. This combined method is based on techniques used in the commercial fluid dynamics simulation package FLOW-3D developed by Flow Science, Inc. A sparse linear system in pressure and velocity components is solved by using the generalized minimal residual method with ILUT preconditioner to advance the simulation of unsteady flow in time. -- Creative use of object oriented programming, data abstraction and template metaprogramming paradigms enables us to implement principle computational fluid dynamics concepts, directly, into the computer code developed in this thesis. This results in a computer program that is easier to understand and maintain. The C++ programming language is chosen as the implementation language since it provides direct support of these modern programming paradigms. Automatic generation of the program code from templates augmented with compile time optimizations and function inlining reduces the size of a manually written code up to four times and meets the high level code efficiency requirements at the Fortran level. -- This numerical simulation tool is applied to the problem of unsteady, laminar, two-dimensional flow of a viscous incompressible fluid past a transversely oscillating circular cylinder in the presence of a free surface. The results of this thesis represent the first comprehensive numerical study conducted on this problem to date. The code validations are presented in special cases and good comparisons with previous experimental and numerical results are obtained.

abstract: In this study, different estimators of probability density functions and hazard rates are constructed under randomly right censored data. Nonparametric approaches are adopted under the assumption that the density and hazard rate has no specific parametric form. Some currently available methods of density and hazard rate estimation are compared to a modified approach. It is shown that wavelet estimators are competitive with the other available methods, and that no specific method can be uniquely used for all subdensities.

abstract: An arteriovenous fistula is an abnormal direct passage between an artery and a vein. The existence of an arteriovenous fistula generates a high output low total peripheral resistance state that resembles the hyper-haemodynamic condition of several diseases such as vascular injury, congenital malformation, chronic severe anemia, severe hepatic or renal disorders, and septic shock. In the present study, we investigated the haemodynamic changes in rats with chronic arteriovenous fistulae and the haemodynamic effects of noradrenaline, arginine vasopressin, and sodium nitroprusside in this model. -- Creation of a chronic fistula between abdominal aorta and inferior vena cava increased cardiac output compared to sham-operated rats. The haemodynamic factors when compared to respective values in sham-operated rats changed in the following ways: 1) total peripheral resistance and resistance to venous return decreased; 2) heart rate and cardiac contractility based on dP/dt values recorded remained stable at the baseline level; and 3) blood volume and mean circulatory filling pressure increased. The augmentation of total blood volume, mean circulatory filling pressure and reduction in vascular resistance together contributed to the increase in cardiac output. -- Noradrenaline infusion did not change the cardiac index in rats with chronic arteriovenous fistulae. Administration of noradrenaline 1) increased total peripheral resistance and resistance to venous return; 2) increased heart rate and cardiac contractility based on dP/dt values recorded; and 3) did not change total blood volume but increased mean circulatory filling pressure. The positive effects of noradrenaline on heart rate, cardiac contractility, and total body venous tone tended to increase cardiac index. However, the increase of cardiac index was prevented due to the increase in total peripheral resistance and resistance to venous return. -- Administration of arginine vasopressin did not change the cardiac index in rats with chronic arteriovenous fistulae. Upon arginine vasopressin infusion, 1) total peripheral resistance and resistance to venous return increased; 2) heart rate did not change while cardiac contractility increased based on dP/dt value recorded; and 3) total blood volume and mean circulatory filling pressure increased. Unlike its actions in the intact animal, administration of arginine vasopressin ·in rats with chronic arteriovenous fistulae reversed the preload-afterload mismatch by increasing mean circulatory filling pressure and total blood volume with little effect on resistance to venous return. Therefore, cardiac index did not fall despite of elevation of the afterload. -- Administration of sodium nitroprusside had limited effects on cardiac index in rats with chronic arteriovenous fistula. The circulatory parameters altered in the following manner: 1) total peripheral resistance and resistance to venous return remained at the baseline level; 2) heart rate did not change while cardiac contractility decreased at the highest dose based on dP/dt value recorded; and 3) total blood volume and mean circulatory filling pressure was kept unchanged. Due to the special condition in our experimental model such as low vascular resistance and maximal vasodilation, administration of sodium nitroprusside had limited haemodynamic effects.

abstract: St. John's harbor is located on the Northeast coast of the Avalon Peninsula on the Island of Newfoundland. During the summer and fall of 1999 and 2000, two continuous observational program were carried out in order to determine the circulation in the Narrows of the harbor and the influence of external forcing from Avalon Channel. Observational current data in both years show that the axial current in the Narrows has a two-layer vertical structure. A strong seasonal bottom outflow was found in the center of the Narrows in both years, and it keeps strongest in August and September. Empirical Orthogonal Function (EOF) analysis applied to the axial subtidal currents in 2000 shows that mode 1 contains over 40% of the total variance and mode 2 contains 27% of the total variance. Coherence analysis result indicates that mode 1 represents the influence from local wind stress and mode 2 represents the effect from external force outside the harbor. Comparison between observation current and wind speed shows that wind force has a direct influence on the surface current and a counter influence on the current in the lower layer. The result of a two-layer barotropical model driven by wind forcing shows a high correlation with EOF mode 1. The counter effect of wind force on the lower layer also occurs in the model, and can be explained as the conservation of the volume in the harbor.

abstract: In this article, we develop tests for equality of response curves. We assume that the mathematical expression of the response curves are unknown. Consequently, we exploit the adaptive properties of wavelets to construct a wavelet representation of the curves. Then, we develop an approach which combines the False Discovery Rate (FDR) technique and the universal thresholding approach, widely used in data denoising, for detecting differences between the curves. We also discuss some methods based on the general F-test. We consider several examples under a variety of conditions such as unequal variances, unequal number of observations, and distinct design points. The size and power performances of the tests are reported. We present two real examples at the end of this article.

abstract: This study is a part of the research project on development of a database and methods for data mining of ocean data. The first part of the project describes the implementation of the relational database management system (RDBMS) for ocean data. The second part of the project introduces a clustering method for identification of regions with homogeneous behavior of ocean parameters. Three algorithms K-means, Expectation Maximization (EM), and Farthest-First (FF) were implemented and evaluated in applications to the sea surface temperature data (SST). The clustering method was applied in analysis of two climate indices of the North Atlantic Ocean derived from the past observations of SST. The first one is associated with the North Atlantic Oscillation (NAO) and the second one with the variability of the Meridional Overturning Circulation (MOC). The two climate indices capture the most important long term variability of MOC and NAO.
