abstract: This research concerns itself with the identification of prehistoric cultural remains as represented at the multicomponent Beaches site, DeAk-1, Bonavista Bay. Several cultural traditions are known for this area and the Beaches site produced evidence of Maritime Archaic, Dorset and Beothuck groups. A chronological framework for these occupations is attempted on the basis of radiocarbon dating, stratigraphic position, and comparisons to other sites and cultural sequences. The interpretation of spatial arrangements of artifacts and habitation features is offered in an attempt to reconstruct their settlement patterns. Inferences on their subsistence activities is based on ethnographic data, the limited faunal remains, and reconstruction of the regional resource potential. -- Occupational evidence at this coastal site occurred in two stratigraphically distinct layers. Cultural Layer 1 contained lithic artifacts attributed to Maritime Archaic, Dorset and Beothuck groups all in a single three inch occupation layer. Cultural Layer 2 was bottommost and clearly distinct with artifacts pertaining entirely to the Maritime Archaic tradition. -- This lower Archaic component is characterized by chipped stone biface forms - bipointed, ovate, lanceolate and stemmed. Scrapers are present in the large retouched flakes but a formal flake end scraper category has not been identified. The ground stone industry - celts, a single ground slate point and abrader, is not present in large amounts. A blade-core industry is unique and definitely part of this Archaic component. Three radiocarbon dates, 1740 B.C., 1890 B.C., and 2950 B.C. indicate the early temporal position of their occupation. -- The upper Archaic component reflects cultural continuity through these Archaic groups with identical chipped stone forms occurring. Temporal and stylistic variations are seen in the greater variety of stemmed points, flake unifaces, and the presence of flake end scrapers. The ground stone industry is well established although ground slate points were not found. The blade-core industry is also present in this later Archaic component although examples tend to be cruder. A guess-date of 1500 B.C. may validly indicate the initial Archaic occupation in this stratum. It may have terminated just prior to Dorset intrusion into Newfoundland and Bonavista Bay. -- The Dorset occupation was probably initiated during the early centuries B.C. This early population movement is postulated on the basis of a few artifacts considered time-sensitive. The main Dorset occupation however occurred during the first half of the first millennium A.D. A date of A.D. 300 from a Dorset hearth supports this interpretation. -- An influx of Indian groups is seen towards the termination of the Dorset period. These groups represent the initial Beothuck population in Newfoundland. The Beaches site provided only six corner-notched points which we can ascribe with certainty to these people. As a further reflection of our inadequate knowledge of Beothuck prehistory, these cannot be assigned to any temporal position in the Beothuck development. -- The reconstruction of subsistence-settlement patterns reveals a basic coastal-interior adaptation for all cultural groups. A spring to fall coastal occupation for specialized sea mammal exploitation is postulated. Interior subsistence is based on the large congregating winter herds and a deep interior penetration and interior settlement was necessary. This was probably facilitated by the large river systems in the Bonavista Bay area. This regional distribution of abundant coastal resources among the many islands and reaches plus interior caribou herds provided the establishment of similar settlement patterns for the various cultural occupations in Bonavista Bay.

abstract: Drug non-compliance, particularly among the elderly, has become a major concern with all professionals within the health care system. Many of the medical problems experienced by the elderly can be linked directly to drug non-compliance. Rather than drugs being an aid to recovery after illness or a stabilizer in the treatment of long term medical problems, they are frequently a prolonging factor, if not the primary factor in the cause of illness. Many of the elderly are multi-prescription and over-the-counter drug users. They are also recurring users of hospital beds. The reason for entry into hospital by the elderly is often the result of drug non-compliance. It is maintained by health professionals that information and education on drug use aimed directly at the elderly could reduce the number of elderly admitted to hospital because of drug non-compliance. Information and education programs would also enable the elderly to cut down on their drug consumption at home, resulting in a better state of health. At St. Clare's Mercy Hospital School of Nursing attempts were being made to eliminate the problem of drug non-compliance through pre-service training of student nurses and through cooperative efforts with other health professionals connected with the hospital. Because of the complexity of the problem, heavy workload, and constraints of time, the teaching staff at the school of nursing were unable to thoroughly review the problem, and design, develop and implement a program appropriate for use by all health professionals associated directly with the elderly and their problem of drug non-compliance. As a solution to the problem an information program in the form of a slide tape presentation was developed. The terminal objective was to solve the problem of drug non-compliance and the elderly. Through implementation of this program the elderly were encouraged to inform and discuss their drug taking habits with their doctor, pharmacist and public health nurse, to ensure an awareness of good drug compliance. The slide tape presentation was produced in accordance with an instructional development model that consisted of four major steps. These steps included defining the problem, designing the presentation, evaluating the presentation, and developing a dissemination plan.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: A large number of cells from the lateral aspect of the supramammillary nucleus (SUML) and the medial septum complex (MSC) innervate the dentate gyrus of the hippocampus. It has been demonstrated that electrical prestimulation of the SUML or the MSC enhances perforant path-dentate gyrus evoked field potentials. Considering the large number of fibres that pass through these regions, the effects glutamatergic stimulation of these regions had on dentate gyrus field potentials in urethane-anaesthetized rats was investigated. The perforant path was stimulated at a rate of 0.1 Hz, evoking an EPSP and a population spike in the dentate gyrus granule cell layer. L-glutamate was delivered by pressure injection (500 mM, 100-150 nl). In a second experiment, concomitant measures of hippocampal EEG, spontaneous unit activity, and the evoked potential recorded at the molecular layer were also taken. As well, the effects of glutamatergic activation of these areas on paired-pulse inhibition was investigated. -- Glutamate ejection to the SUML and MSC produced a significant enhancement of the population spike. The duration of enhancement ranged from 2 to 54 min (X = 18.4 min) and from 1 to 49 min (X = 10.5 min) after SUML and MSC activation respectively. A consistent, but relatively short increase in the EPSP slope was demonstrated after MSC activation but not after SUML activation. No consistent effects were found on the 2 latency measures. -- SUML and MSC activation induced theta in 4 of 7 (duration= 10-45 s) and 7 of 10 animals (duration= 20-112 s), respectively. Theta induction preceded spike enhancement and occurred for a shorter duration than the enhancement. -- After either SUML or MSC activation the effects on spontaneous unit activity were mixed. However, all changes in firing rate preceded spike enhancement, and their duration rarely coincided with the duration of the spike enhancement. -- Results of paired-pulses (lSI= 20-30 ms) given during SUML activation demonstrated evidence of reduced feed-back inhibition, despite an absence of the enhancement of the first spike of the pair. MSC activation produced a reduction of feed-back inhibition in one of three animals where the first spike of the pair was enhanced.

abstract: The effectiveness of a group psychoeducational therapy approach to assess anger management was researched. A pilot anger management program at a mental health facility ran for eight weeks, two hours a week. It involved nine outpatient participants selected from referrals made by organizations in the community. During the group sessions, participants recorded their own perceptions of their anger using a questionnaire designed specifically for this project. These questionnaires were administered during the first and final sessions. The questionnaires were analyzed to determine if the sessions were effective in reducing the participant's perceived level of anger. Clinical observations were documented by the therapists to assess changes in the anger management skills of the participants. Statistically significant improvements in anger management skills were identified and all members of the group felt that they benefited from the group sessions and could approach their anger in a more appropriate manner. The findings are deemed to support the use of outpatient group psychoeducational anger management. A detailed description of the educational component of the program is offered.

abstract: This thesis analyzes fictional constructions of the Antarctic during the nineteenth century by focusing on the representative texts The Rime of the Ancient Mariner (1798) by Samuel Taylor Coleridge, The Narrative of Arthur Gordon Pym of Nantucket (1838) by Edgar Allan Poe, and An Antarctic Mystery (1897) by Jules Verne. I have chosen these works because they are canonical, and their representations of the Antarctic therefore carry significant cultural resonance. Postcolonial and ecocritical thought help frame my treatment of them. The scholarship of critics like Said, Boehmer, Loomba, Huggan, Tiffin, and Plumwood coalesce in this thesis to provide a hybrid lens for examining processes by which non-human nature is othered. This perspective is invaluable in unpacking how discursive constructions of Antarctica by authors like Coleridge, Poe and Verne confer placehood on the region. -- Antarctica's remoteness and inhospitableness kept all but a handful of people from reaching its shores in the nineteenth century. This limited its ability to be constructed socially as a place, but in turn also inspired the literary imagination to create identities for it. Despite the limits on a socially constructed placehood for Antarctica during this period, I contend that the region is granted various identities through its representations in literature. Most prevalent among these is a tendency to figure the Antarctic as a mutable and ambivalent space. The literary figurations of Coleridge, Poe, and Verne are indicative of how the Imperialistic West conceived of Antarctica before it began to claim or assert control over its landscape.

abstract: Inversion modelling problems are ill-posed and non-unique and, as such, they have an infinite number of potential mathematical solutions. By using the joint inversion of two different but complementary geophysical datasets a model can be produced in which there can be a greater degree of confidence. To test the joint inversion methodology a code for the modelling of borehole seismic tomography and gravity data was used to attempt to reproduced geologically-realistic synthetic Earth models. A number of 2D and 3D synthetic Earth models, based on the geology of the Eastern Deeps zone of the Voisey's Bay deposit in Labrador, were constructed. These models consist of unstructured triangular and tetrahedral meshes. The 2D models were based on conceptualized models of the Eastern Deeps and are varied in complexity. The 3D tetrahedral model was built based on Datamine wireframe model of the Eastern Deeps. Single property and joint inversions were carried out to evaluate the ability of the joint inversion methodology to reproduce the models and to determine which inversion parameters were most crucial in generating the best inversion results. Through these tests it has been shown that the joint inversion code was able to locate a buried high contrast target in 2D and 3D cases. During 3D tests it has been concluded that a balance between the noise levels, number of cells in the inversion mesh, seismic acquisition array and gravity measurement locations had to be carefully considered in light of the available memory capacity and computation time in order to attain reasonable joint inversion results.

abstract: In 2001, full-scale archaeological investigations were carried out in Nisbet Harbour, Labrador, at Hoffnungsthal, the site of the first Moravian mission station to the Labrador Inuit. When completed, the excavations had revealed several architectural features of the mission house, and uncovered thousands of artefacts dating to the few weeks in the summer of 1752 when the missionaries built and occupied the site. This thesis gives a history of the 1752 expedition, describes the archaeological findings made in Nisbet Harbour, then reconstructs the mission house based on available archaeological and historical data. Finally, Hoffnungsthal's form and design is discussed with reference to its historical, architectural, and cultural context.

abstract: In order to gain a clearer vision of the effectiveness of programs for disadvantaged adults, I observed a Job Readiness Training (JRT) class which ran for twenty weeks at a community college in Newfoundland. Through participant observation, key informant interviews, and subsequent analysis and interpretation, I addressed the gap between current theoretical assumptions within adult education and effective practice in a classroom of marginalized adult learners. The research revealed a dimension not integrated into the elements of prevailing theory. -- It became clear that the culture of the students and that of the educational system were incongruent, resulting in outcomes which did not mirror the course objectives. Additionally, the conventional wisdom of adult education did not fully consider the inclusion of adults lacking in self-motivation and self-direction. These discrepancies were clearly seen in student attitudes towards work and job stations, the students' values interpretations, and the sex, drugs, rock 'n roll culture which formed the social and dialectic context for the classroom. Aspects of adult education practice did provide a climate in which some students began to address facets of work, education, and self-knowledge which they had previously disregarded, although future expectations and planning did not appear to change. -- Course length, instructor turnover, and unmotivating work experiences caused some of the practical problems that were observed. Students' lack of internal locus of control and of future orientation, and their experiences with the realities of long term dependence on income security measures, contributed to the variance between student needs and course objectives and outcomes. -- A grounded theory framework for ongoing, constant data comparison was used to create a deeper understanding of the social patterns observed in the classroom. Underlying themes emerged which constituted the mid-range theory and provided a better perception of the needs of disadvantaged adult students. These themes – the focused sense of immediacy, the incongruence of values and objectives among students, course and instructors, the language element which reflected the culture of the students, and the lack of future orientation - together identified the gaps in the current provision of programming and accepted practice.

abstract: Asthma is the most common chronic illness of childhood. It is a leading cause of school absenteeism and accounts for a major portion of pediatric admissions to emergency departments and hospitals. When a child is diagnosed with asthma, parents become responsible for the long-term management of a chronic condition that may be characterized by unpredictable and irregular episodes. -- Most of the research concerning parents and childhood asthma is focussed on mothers. The small number of studies in which mothers and fathers were compared revealed that differences do exist between their experiences and responses. Paternal perspectives and experiences of caring for a child with asthma have been sparsely explored. -- This phenomenological study used van Manen's (1994) method of inquiry to explore the lived experience of fathers who have children with asthma. A sample of eight fathers with children aged 7 to 11 years who had been diagnosed with asthma were interviewed in order to find out what their experiences were like. From the analysis of the interview data, five themes were identified: feeling relief in knowing the diagnosis, learning the ropes, living with concern, being vigilant, and being comfortable with asthma management. The findings from this study have implications for nursing practice, education, and research. Understanding the experience of fathers who have children with asthma, and gaining insight into their needs and concerns is a first step to providing supportive nursing care. It is important to include fathers in future research studies and examine their unique experience in parenting ill children.

abstract: Objective: To investigate maternal serum screening (MSS) in Newfoundland and Labrador. -- Design: Cross-sectional anonymous physician and post-partum women surveys conducted between September and December 2003. Aggregate laboratory data for 2003 were also assessed. -- Population: Physicians practicing antenatal care in Newfoundland and Labrador in the previous 12 months (n = 490). Women (n = 300) who had recently given birth. -- Results: The response rates for the physician and patient surveys were 60.4% (n = 293) and 66.7% (n = 200) respectively. Most physicians (88.8%) reported that they offer maternal serum screening to their patients. These physicians were divided among those who offered MSS to all women (63.5%) and those who offered MSS to selective groups of women (36.5%). Physicians who were younger, female and educated in Canada were more likely to offer MSS than physicians who were older, male and educated outside of Canada. Obstetricians were more likely to offer MSS and to offer the screening test to all women than family physicians. The majority of both physician groups reported that they would prefer a first trimester screening test. -- The majority (62.9%) of patients surveyed reported discussing MSS with their physician. Less than half (46.2%) of these women chose to undergo the prenatal screen. Women who underwent MSS were significantly older than women who did not undergo the screening test. Twenty seven percent of patients surveyed underwent MSS. -- Data obtained from the Provincial MSS Program indicated that 22% of women undergo MSS. The overall false positive rate 1 associated with MSS in Newfoundland and Labrador was 13.1%. -- Conclusion: MSS is not being used as a population based screening test. It is being offered to and used by selected groups of women. Further education and promotion of this prenatal screening test are necessary.

Masters thesis, Memorial University of Newfoundland.

abstract: The Colombian Government and its FAO Project for Marine Fisheries Development included in its plans for research the biology of spiny lobsters to determine among other things the minimum legal size at which they could be fished. This study was done on the Guajira coast where statistics of catched showed them to be the most abundant in Colombia. -- The objective of the study was to know more about the biology of the species in this area, and to establish a minimum legal size limit as a safeguard until at least first maturity was reached. -- The hydrographic data considered were temperature, current systems (especially near Cabo de la Vela), because in this area there was good fishing for lobster and apparently a nursery for lobsters. The temperature and salinities remained constant throughout the year. The length weight relationships for males and females showed that males became larger than females, and that the weight increase was 3.47 times, but in the females weight did not quite reach the cube of the tail length. On the other hand, from moulting data it is possible to say they reached a 32% increase in weight in one moult. -- Maturity studies showed that embryogenesis was approximately equal to oogenesis and there were apparently three main spawning peaks in a year (August, September, and January; Fig. 7). -- According to the data gathered during the sampling period, 65 rom was the carapace length for first maturity, and between 80 to 90 mm the largest size group. -- It was found that the rate of growth was more accelerated in males than in females, there being a difference of 27 mm (approximately) between males and females. -- In some specimens the stomach was examined, but unfortunately was found empty in almost all cases, perhaps due to the method of transport used, but in general the main fragments found were fish bones, crustaceans, and filamentous algae among the most important. -- Of the different places considered as lobster grounds in Colombia, the Guajira area seems to be best, because this place offers at least two nursery areas and because the bottom conditions are favourable in "turtle" grass, sea weeds, rocks, and coral formations.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract:
Due to economic reasons arising out of deregulation and open market of electricity,
modem day power systems are being operated closer to their stability limits. When a fault
occurs, there is a great possibility of occurrence of cascading outages, as observed in the
August 2003 Blackout in the North-East USA and Canada. Power system voltage
stability is one of the challenging problems faced by the utilities. Innovative methods and
solutions are required to evaluate the voltage stability of a power system and implement
suitable strategies to enhance the robustness of the power system against voltage stability
problems. This is the motivation behind the research carried out as a part of the PhD
program and presented in this dissertation.
Artificial neural networks (ANNs) have gained widespread attention from
researchers in recent years as a tool for online voltage stability assessment. Two major
areas requiring investigation are identified after doing a thorough survey of the existing
literature on online voltage stability monitoring using ANN. The first one is the effective
method of selecting important features among numerous possible measurable parameters
as potential inputs to the ANN. The second one is the feasibility of using a single ANN
for monitoring voltage stability for multiple contingencies. In the first phase of the
research, a regression-based method of computing sensitivities of the voltage stability
margin with respect to different parameters is proposed. Using the sensitivity
information, important features are chosen selectively to train separate Multilayer
Perceptron Networks (MLP) to monitor voltage stability for different contingencies.
In the second phase of the research, an enhanced Radial Basis Function Network
(RBFN) is proposed for online voltage stability monitoring. Important features of the
proposed RBFN are: (1) the same network is trained for multiple contingencies, thus
eliminating the need for training different ANNs for different contingencies, (2) the
number of neurons in the hidden layers is decided automatically using a sequential
learning strategy, (3) the RBFN can be adapted online, with changing operating scenario,
(4) a network pruning strategy is used to limit the growth of the network size as a result
of the adaptation process.
In the next phase of the research, a sensitivity-based voltage stability
enhancement method is proposed, considering multiple contingencies. Considering the
limitations of the existing analytical methods, the sensitivities of the voltage stability
margin with respect to parameters are found by using the RBFN proposed in the second
phase of the research. Using the sensitivity information, correct amounts of generation
rescheduling are found by using linear optimization. Case studies are presented
throughout different sections of the thesis to illustrate the application of the proposed
methods.

abstract: This thesis examines issues related to the relationship between the two languages comprised in a bilingual child's linguistic competence. The data investigated come from a longitudinal case study of an English-French bilingual child (2;00.04 to 4;02.25). The first topic under investigation relates to the reasons behind code switching as well as the constraints on the manifestations of this phenomenon. These constraints result in morphosyntactic combinations that can or cannot occur in code-switched utterances. The data are also analyzed from the perspective of the acoustic manifestation of stress in each language. The results of this acoustic investigation suggest that the child has two separate stress systems and that she has mastered the main phonetic cues related to the manifestation of stress in each language. Overall, this study supports claims in the current literature that bilingual speakers do indeed have separate grammars in their linguistic competence.

abstract: This thesis investigates climatological aspects of a subarctic alpine treeline site in the Mealy Mountains, Labrador. The first of two manuscripts looks at a method of regional climate modeling (statistical downscaling) to produce temperature scenarios for the future and to assess the applicability of large-scale models (global climate models) for regions of complex topography.  Both the GCM and statistically downscaled models predict warming for the study site, especially for winter months. However, the output of GCMs was determined to not capture the local climatic influences of this region, and thus produces scenarios that smooth over the signal of future climate change. The second manuscript produces a descriptive climatology of the study site and also investigates the relationship of the treeline with the climate. It was determined that the current climate regime of the Mealy Mountains is not a limiting factor to tree growth beyond its current elevation; however, recent changes and future climate predictions may encourage the recruitment and establishment of spruce trees above their current position.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Seven millet varieties grown in Sri Lanka (proso, foxtail, finger (Ravi), finger (local), kodo, and little) and India (pearl) were used in this study. Soluble and bound phenolics obtained by solvent extraction were used to evaluate antioxidant, DNA scission and enzyme inhibitory and antiproliferative activities by several chemical and biological methods. Distribution of phenolics and their antioxidant activity was assessed in dehulled grains and hulls separated by air classification. Phenolic compounds in free, soluble conjugates and insoluble bound fractions were identified and quantified. In addition, accessibility of phenolics in the digestive tract was determined using a simulated in vitro digestion model and colonic fermentation. The contents of total phenolics (TPC),total flavonoids (TFC) and proanthocyanidins (PC) as well as scavenging activities of test compounds were evaluated using superoxide, hydroxyl, peroxyl, 2,2-diphenyl-l-picrylhydrazyl (DPPH) radical, H₂O₂, and singlet oxygen. Different concentrations of extract were used to determine their IC₅₀ values. In addition, the ferrous chelating and reducing activities of extracts were measured. The highest phenolic content of soluble phenolics of millet grains was obtained with 70% (v/v) acetone for 25 minutes under reflux conditions. The TPC of soluble and insoluble bound phenolic fractions of millet varieties were 7.2 - 32.4 and 2.2-81.6 μmol ferulic acid eq/g defatted meal, respectively. This demonstrates that bound phenolics are important contributors to antioxidant potential of millets. Kodo millet showed the highest soluble phenolic content followed by finger (local), finger (Ravi), little, foxtail, pearl and proso millets. Millets with dark brown pigmented testa and pericarp possessed a higher soluble phenolic content than those with white or yellow testa and pericarp. The TFC of soluble and insoluble extracts were 1.2-33.7 and 0.3-4.5 μmol catechin eq (CE)/g defatted meal, respectively. The soluble extracts of finger (local) millet had the highest PC (311.28 μmol CE/g defatted meal). All varieties exhibited effective radical, H₂O₂ and singlet oxygen inhibition, reducing activity as well as ferrous ion chelating power which varied according to the assay employed and the variety used. Several hydroxybenzoic and hydroxycinnamic acids and flavonoids were identified and quantified by HPLC analysis. In general, ferulic and ρ-coumaric were found to be the major phenolic acids followed by protocatechuic, caffeic, sinapic, ρ-hydroxybenzoic, gentisic, and vanillic acids and their contents depended on the variety and the form present in the grain matrix. Flavonoids identified were flavones, flavan-3-ol monomers and dimers, and flavanonols. All seven varieties effectively inhibited oxidation in a pork model system, and stripped corn oil.  At a concentration of 0.5 mg/ml all extracts inhibited oxidation by 16-88% in the linoleic acid emulsion system. All phenolic extracts inhibited Cu (II)-induced human LDL and liposome oxidation and DNA scission. Millet extracts at 0.05 mg/mL inhibited LDL cholesterol oxidation by 1-41% and exhibited a dose-dependent inhibition of DNA scission. The antiprolifeative studies showed that kodo millet extract inhibited HT-29 cells proliferation in the range of 75-100% after 4 days of incubation. The hulls from dehulled millets had higher TPC and antioxidant activity compared to their whole, dehulled and cooked grain counterparts. The phenolic extracts of dehulled millet grains, following in vitro enzymic digestion under simulated gastrointestinal conditions and colonic fermentation, showed effective antioxidant activity and were accessible under physiological conditions.

abstract: The regulation of cholesterol homeostatsis is of considerable interest because of the host of studies that show a clear positive relationship between plasma cholesterol levels and the risk of coronary heart disease. It has become apparent that plasma cholesterol levels are affected by a number of life style factors including the amount and type of fat in the diet. However, the mechanisms whereby dietary fat affects plasma cholesterol remain unclear. In this study we have investigated the effects of the levels and types of dietary fat on the cholesterol homeostasis. We used the FIB strain of hamster as a model as this strain has been shown to be sensitive to dietary fat induced atherosclerosis. We propose that this sensitivity reflects differences in the regulation of lipid metabolism between the F1B and the parent strain of hamsters. -- Cholesterol homeostasis in the liver is tightly regulated by several sterol-sensitive regulatory proteins and receptors, including LDL receptor, HMG-CoA reductase, ACAT, CYP7, and SREBPs. It is postulated that the ER cholesterol is the cholesterol regulatory pool plays a major role in the regulation of these enzymes of the whole cell. -- We examined the effect of different dietary fats on the activity or expression of these proteins and observed that the activities of these enzymes are not directly regulated by the fats and cholesterol in the diet; instead, they appear more responsive to changes in the lipid environment of the microsome in the F1B hamster liver. Both the HMG-CoA reductase and the ACAT activity are positively correlated with the level of n-3 fatty acids in the microsome, and ACAT activity also depend on the content of microsomal cholesterol. -- We suggested that the levels of n-3 fatty acids and cholesterol in the diets may change the lipid composition microsomal membranes. This might alter membrane fluidity or the distribution of the key enzymes and regulatory proteins in the membrane of the ER. We suggest that the formation of microdomains (rafts) may sequester much of the cholesterol into pools that are separate from the cholesterol regulatory pool in the ER. However, further studies on the lipid composition of these microdomains are needed for clarify our hypothesis.

abstract: This work describes several new experimental observations made by the author in the collision-induced infrared absorption spectra of molecular hydrogen at liquid nitrogen and room temperatures for densities up to 660 amagat. The experiments were carried out with a 2 m low-temperature high-pressure absorption cell of the transmission type. The spectral region investigated extends from 3500 to 10,000 cm⁻¹. -- Collision-induced vibration-rotation U transitions (ΔJ = +4) of the hydrogen molecule in its fundamental band have been observed for the pure gas at 77 K for densities in the range 430 - 660 amagat and for the binary mixtures, hydrogen-xenon, and hydrogen-krypton at 298 K for total gas densities ~ 450 amagat. The high frequency tail of the quadrupolar S transitions which overlaps the U transitions has been separated from the experimental profiles by the method of profile analysis. The spectrum of the U transitions is interpreted in terms of the hexadecapolar induction mechanism. From the experimental integrated binary absorption coefficients of the U transitions, appropriate values of the hexadecapole moment matrix elements of the hydrogen molecule are derived. -- Spectra of the collision-induced first overtone band of hydrogen in binary mixtures with krypton and xenon at 298 K for densities up to ~ 450 amagat have been recorded for the first time. From an analysis of the profiles of the enhancement of absorption, the frequency shifts δν₀ and the half-widths δ have been determined. Unusual occurrence of some H₂ double transitions was observed. The observed frequency shifts of the quadrupolar lines are negative and level off at high densities, qualitatively in the same way, but with larger shifts, as those observed in the fundamental. The observed half-widths of the quadrupolar lines were found to increase with the density of the inert gas, and to be quite sensitive to the base density of the hydrogen. Both observed line-shifts and half-widths are expected to have larger values than the true ones because of overlapping double transitions obscuring the single transition lines. -- During the above mentioned experiments with hydrogen, it was observed that especially in the spectral region 6800 - 7400 cm⁻¹ more light reached the detector with compressed hydrogen in the cell than when the cell was evacuated. The spectral profiles of this phenomenon in the region 6800 -7400 cm⁻¹ and their density dependence have been determined and it is speculated that upper states are populated by collision-induced absorption in the region of the first overtone and the subsequent radiative emission transitions follow the same selection rules that are known for collision-induced absorption.

abstract: Traditionally, complexes containing heavy and precious metals such as palladium have been used to catalyze a wide range of C-C cross-coupling reactions. However, there are many drawbacks to using these types of catalysts because of their toxicity and/or price. More recently, in the interest of sustainability, there has been a rapid increase in the study of iron-based catalysts. Iron is inexpensive, non-toxic, environmentally benign, and readily available as it is one of the most abundant elements on Earth. -- The catalytic formation of diarylmethane motifs is a very important synthetic tool, with applications in pharmaceuticals and biologically active compounds. To date, the formation of diarylmethane motifs by the iron-catalyzed C-C cross-coupling of benzyl halides with aryl Grignard reagents has been reported to be unsatisfactory, giving low yields and poor electivity resulting in the formation of homocoupled by-products. The development of an air stable, non-hygroscopic, single component iron-based catalyst which can effectively generate diarylmethane motifs is of particular interest. -- Recent research in the Kozak group has focused on the use of iron(III) complexes supported by amine-bis(phenolate) ligands as potential catalysts for C-C cross-coupling reactions. A series of structurally authenticated iron(III) complexes of tridentate amine-bis(phenolate) ligands have been prepared and their potential as catalysts for the C-C cross-coupling of aryl Grignards with benzyl halides, including chlorides, has been explored. The results of catalysis studies, as well as structural and spectroscopic characterization of the metal complexes will be presented.

abstract: The study was conducted to assess long-term impacts of the anticipated changes in temperature, precipitation and humidity in the five Arabian Gulf countries over the next hundred years. The impact of the anticipated climatic changes on human health was estimated based on the Intergovernmental Panel on Climate Change (IPCC) database. Long-term simulated records for A2 and B2 scenarios were retrieved for longitude 41.25°E to 61.875°E and latitude 9.278°N to 27.833°N for Bahrain, Oman, Qatar, United Arab Emirates (UAE) and Yemen using the following three global climate models (GCMs). -- 1. Hadley Centre Global Model (U. K) --  2. Canadian Centre for Climatic Modeling and Analysis (CCCMA) -- 3. National Centre for Atmospheric Research (NCAR) Model (USA) -- Using average of 1970 to 2000 values as baseline values, the changes in the humidity, temperature and precipitation were estimated for the period 2020 to 2050 and 2070 to 2099. The study showed inconsistency in the prediction of temperature, precipitation and humidity by the above three GCMs, probably due to lack of validation and poorly defined boundary conditions for the region. The predicted temperature increase by NCAR was conservative in 100 years as compared to the other two models. While CCCMA and NCAR predicted higher precipitation fluctuations as compared to Hadley model. The higher uncertainty and inconsistent trends in data prediction as observed by these GCMs require further investigation by validating an appropriate regional climatic model. The climatic variations play a critical role in increased morbidity and mortality due to spatial and temporal spread, timing and severity of infectious diseases. The summarized impacts of climatic changes on the human health based on the empirical approaches project significant increases in disability adjusted life years (DALY) and mortality rates. Amongst the five Gulf coastal countries Yemen and Oman are found more adversely affected with higher anticipated mortality and DALY rates than Bahrain, Qatar, and UAE.

abstract: This study determined whether the four-week work exposure component of the two-year Business Administration (Accounting) diploma program at the College of the North Atlantic was meaningful to its students. Data was collected through observation during two feedback sessions, individual interviews and written work term reports. -- Seven randomly selected students from the Business Administration (Accounting) program identified psychosocial development and the application of in class learning as crucial to making the experience meaningful. Students indicated, however, that the experience was too short for learning to occur. As well, the timing of the work term at the end of the program meant it was not an integral part of their program and resulted in ineffective reflective learning exercises. As a result, the researcher concluded that the experiential learning process was not complete. Based on this research, it is recommended that the College review the experiential learning component of its programs in the context of policies and procedures, work term structure and necessary support services to ensure that the experiential learning process is complete.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Understanding patterns of animal distribution and abundance and their causes is at the heart of ecological investigations with implications for conservation, resource management, theoretical development and testing. Surveys to evaluate the localized distribution and abundance of common eiders (Somateria mollissima) nesting in Labrador were conducted from 1998 to 2003. Information was compiled and analysed with respect to clutch size, nest initiation, nest density, abundance, population trend, spatial distribution, colony dynamics, as well as interspecific and abiotic habitat relationships. Eiders showed a north south-clinal variation in nest initiation with birds in the south laying earlier then birds in the north. There was significant interaction between annual and regional variation in life history parameters (nest initiation, clutch size, egg volume) and regional differences in nest abundance and nest density, with the lowest densities in Hopedale, while Nain and Rigolet were comparably high. Overall, eider populations were increasing. Colony dynamics and local population turnover were investigated, and colonization rate was greater than extinction rate, but these varied by region. Interspecific relationships were investigated and significant positive associations were found between nesting eiders and nesting Larids (Larus argentatus and L. marinus), and gulls seemed to track eider colonies over time, but eiders did not track gull colonies. No evidence of a significant relationship between nesting eiders and intertidal resources were found. Negative relationships were documented between nesting eiders, landscape features and ice. This was attributed to increased access to breeding islands by terrestrial predators; however other factors such as colder conditions, or reduced access to prey because of ice obstruction or ice scour might be at play. The effect of spring ice on nesting eiders in Labrador has profound implications for understanding the biological consequences of long-term global climate change. This thesis represents some of the first published information on eider ecology in Labrador, a focal species with ecological and cultural importance, and this research has implications for the regional, national, international conservation and management of common eiders. Findings were interpreted in the context metapopulation theory, source sink population dynamics, conspecific attraction, and the ideal free distribution.

Masters thesis, Memorial University of Newfoundland.

abstract: Exogenous application of norepinephrine (NE) or stimulation of endogenous NE release has been shown to potentiate the perforant path-evoked dentate gyrus population spike (popspike). In vitro studies (Lacaille and Harley, 1985) suggest beta receptor mediation of the enhancement. In contrast, an in vivo study (Winson and Dahl, 1985) implicates alpha receptors. The present study utilizes intracerebroventricular (icv) administration of NE (1, 10, 50, 100 μg) as well as alpha and beta agonists and antagonists in urethane-anaesthetized rats in order to examine in vitro-like bath application conditions in the intact preparation. The effect of icv NE was also assessed in awake, behaving animals. In the anaesthetized rat, NE as well as the beta agonist isoproterenol reliably potentiated the population spike (popspike) amplitude. The alpha agonist phenylephrine potentiated the popspike in a majority of experiments. The icv-induced enhancement was frequently long-lasting for the beta agonist isoproterenol and higher doses of NE (50, 100 μg). Both alpha (phentolamine) and beta (metoprolol) antagonists blocked the NE induced potentiation in a majority of experiments. However, only the alpha antagonism was significant. EPSP slope changes were inconsistent. NE (10 μg) produced a potentiation in the awake, behaving rat which was virtually indistinguishable from that obtained with the same dose in the anaesthetized preparation. These results suggest that the icv methodology is a reliable method of producing popspike potentiation by exogenous NE applicaiton in vivo. Secondly, the results suggest a possible role for alpha as well as beta receptors in the NE potentiation effect in the dentate gyrus. Finally, the results extend the finding of NE induced potentiation to exogenously applied NE in the awake animal.

abstract: In Canada, the rights to silence and legal counsel are communicated to suspects through passages of text known as police cautions. Previous research on comprehension of cautions in Canada, the United States, England and Wales, and Scotland has shown that people rarely comprehend the information contained in police cautions. In the current study, the level of comprehension of two police cautions in a sample of Canadian offenders was investigated, along with the relationship between comprehension, education, and three measures of cognitive ability. Participants (n₁ = 60) were asked to comprehend both a right-to-silence and right-to-legal counsel caution that was presented to them verbally. Comprehension was measured using free recall and recognition tasks (13-item true-false test). Participants were also asked to complete select subtests of the Wechsler Adult Intelligence Scales - Fourth Edition (WAIS-IV; Digit Span and Vocabulary) and a subtest of the Woodcock-Johnson Test of Achievement - Third Edition (WJ-III; Understanding Directions). The results showed that participants demonstrated a poor understanding of their legal rights, as the average comprehension score was 30%. In addition, the measures of cognitive ability were unrelated to caution comprehension scores. A post hoc sample (n₂ = 16; N = 76), whose comprehension was tested without hearing the cautions, demonstrated an average comprehension of 15%. The implication of these findings for the administration of police cautions to Canadian offenders is discussed.

title: Utility-preserving κ-anonymity

abstract: As technology advances and more and more person-specific data like health information becomes publicly available, much attention is being given to confidentiality and privacy protection. On one hand, increased availability of information can lead to advantageous knowledge discovery; on the other hand, this information belongs to individuals and their identities must not be disclosed without consent. A recently proposed concept called κ-Anonymity addresses this conflict between doctor-patient confidentiality and society-beneficial research. -- Several κ-Anonymity-based problems have been proposed in the literature; however, these problems do not adequately address preserving utility for the researcher and their algorithms are not computationally efficient. This thesis highlights these inadequacies through a comprehensive overview of previous research, where it is shown that previous solutions lack sufficient ability to meet specific researcher needs. To this end, new utility-preserving problems are proposed and their computational complexities are analyzed. Many results for κ-Anonymity-based problems are systematically derived through this analysis, including two of particular interest: (1) the first known polynomial-time solvable κ-Anonymity-based problem and (2) the first known algorithm-independent polynomial-time approximation intractability results for κ-Anonymity-based problems.

abstract: This thesis reports the study of a series of novel acetylenic π-extended tetrathiafulvalene derivatives (exTTFs). The detailed research is divided into two major projects. In the first project, acetylenic anthraquinoid-type exTTFs (referred to as TTFAQs) were synthesized and characterized. The target compounds have rigid macrocyclic enyne conjugated π-frameworks which can be constructed by a one-pot, 4-fold Sonogashira coupling strategy. The molecules show interesting solid-state stacking in single crystals, and rich electronic and redox properties as characterized by UV-vis and fluorescence spectroscopy, cyclic voltammetry, and spectroelectrochemistry. In the second project, a series of acetylenic tetrathiafulvalene vinylogues (TTFVs) and their structural analogues, oligoyne-derived TTFs, were synthesized and studied. Two routes are explored for the selective formation of macrocyclic TTFV and acyclic TTFV oligomers. Electronic and redox properties of these molecules were characterized by various instrumental analyses. Oligoyne-TTFs undergo electropolymerization to form stable TTFV-containing polymer films which show electrochromic behavior. Solid-state reactivity of oligoyne-TTFs were studied by differential scanning calorimetric and thermogravimetric analysis. Finally, in a side project, a series of TTFV-centered tweezer-like molecules and TTFV-crown ether hybrids were designed and synthesized as supramolecular hosts for [60]fullerene and metal cations.

abstract: Owing to their unique structural and redox properties, the anthraquinoid type of π-extended tetrathiafulvalene (referred to as TTFAQs) and their D-A functionalized derivatives have offered promising prospects in modern organic electronic and optic materials. This thesis primarily summarizes the research of a series of novel functionalized TTFAQ derivatives, including a series of novel dumbbell-shaped C₆₀-TTFAQ-C₆₀ triad molecules and various donor/acceptor substituted TTFAQ systems. Electronic and optical properties of these compounds were studied by cyclic voltammetry (CV), UV-vis absorption, and fluorescence spectroscopy, and detailed oxidation state spectroscopic properties of the TTFAQ based donor/acceptor systems were characterized. These data contributed to establishing a clear structure-property relationship for these novel TTFAQ compounds, and was also informative to further investigation on their photophysical behavior and photovoltaic applications. In addition, some exploratory investigations on a TTFAQ-cored conjugated molecular switch and a one-pot synthetic strategy for rapidly preparing complex butadiynylene centered systems are reported.

Masters thesis, Memorial University of Newfoundland.

abstract: Systematic arrangement of lake whitefish was reviewed. Morphological features of the transplanted whitefish population in Hogan’s Pond were analysed and compared with the original Lake Erie population. Lake whitefish in Hogan’s has a smaller body size, relatively shorter snout, bigger eyes, longer fins, much shorter depth, more numerous gill rakers than Lake Erie whitefish; and has more lateral-line scales than any other population of the same species in North America, being 85.5. Osteology of Coregonus clupeaformis and in relation to that of other salmonid fishes were reviewed. -- Samples of whitefish were collected in 1965 and 1966. Age-group and age-group VI were dominant in these collections. The mean age for 258 fish was about 5 years. Fish with length between 271-310 mm. (fork length) and weight 201-280 grams constitute more than 62% of the total fish. -- The growth rate of young fish was smooth, however, the growth rate of older fish was so poor that a great degree of emaciation was noted. The length-weight relationship for 258 can be expressed by the equation: -- W = 0.1148 L²·²⁷⁷⁹. -- The average coefficient of condition for 258 fish was 1.072. -- The sexes were almost equally represented (53.3% males). Youngest mature male and female whitefish belonged to age-group II with a length of about 242 mm. (fork length). All fish shorter than 220 mm were immature, longer than 320 mm. were mature. -- Average fecundity of 35 female whitefish examined was 2.954 eggs, with egg diameters ranging from 1.0 to 2.7 mm. -- A rare case hermaphroditism of Coregonus clupeaformis was found in one specimen with ovo-testis on the left gonad. -- Food supply for Hogan’s Pond whitefish was found too small for them. The chief food items for these adult fish are Daphinia sp., Cyclops sp., and Amphipoda. Bottom fauna occupy only small proportions of food contents.

abstract: The biosynthesis of tetrapyrroles is briefly discussed and the important intermediates for chemical synthesis of these compounds are derived by valuable new methods. -- Desulfurization of the pyrrole thiolesters was investigated, and the column reaction was introduced to improve the yield of the products. -- Pyrrole aldehydes, hydroxymethyl pyrroles, and methyl pyrroles could be obtained from the corresponding pyrrole thiolesters in fairly good yields. -- The hydroxymethyl group on pyrrole ring is easily converted to methyl group through chloromethyl group. Both β-hydroxymethyl pyrroles and β-chloromethyl pyrroles are easily converted to β, β¹-dipyrromethanes in acidic medium. -- N-H stretching of α-carbethoxydipyrromethanes is very similar to that of α-carbethoxypyrroles, and shows strong intermolecular hydrogen bonding in nonpolar solvents. α, α¹-Dipyrromethanes which have adjacent oarbethoxy groups show intramolecular hydrogen bonding where as β, β¹-dipyrromethanes do not. -- Infrared, ultraviolet and nuclear magnetic resonance spectra are given for all the new compounds.

abstract: High-strength concrete slabs are frequently used in various structural engineering systems and a wide variety of civil engineering applications. A research program on the structural behaviour of such slabs is being carried out both experimentally and numerically at Memorial University of Newfoundland (M.U.N.). The work reported herein includes the experimental investigation on the tensile behaviour of high-strength concrete and finite element (F.E.) analysis of its slabs. The emphasis is placed upon the importance of the realistic material properties and the need of a valid concrete model in the F.E. analysis. Particular attention has been focused on the post-cracking tensile behaviour of high-strength concrete. -- The complete load-deformation behaviour of high-strength concrete in direct tension, including post-cracking softening response, was obtained by developing direct tension test technique. The test measurements were then characterized into a rational tension softening model. The understanding of the unique tension softening nature of high-strength concrete was enhanced by comparison to that of normal strength concrete in terms of fracture energy, mechanical properties and entire load deformation response. In addition the effect of the cold ocean water on the tensile properties of high-strength concrete was examined. The variability and relations of tensile strengths and compressive strength were also studied. -- Appropriate representation of post-cracking behaviour of reinforced high-strength concrete was developed for the F.E. analysis of its slabs. The developed models and measured stress-strain characteristics of high-strength concrete and reinforcing bars were then incorporated into a proposed plasticity- based concrete model implemented in the context of the 8-node quadrilateral shear-flexible thick shell element. The material model allows realistic concrete strain softening after both cracking and crushing. The validity of the model was established by comparison of F.E. numerical predictions to experimental results of sixteen slabs tested at M. U.N. The model performed satisfactorily in all the cases, with respect to the entire load-deflection response, ultimate load carrying capacity, ductility, and failure mode. -- The F.E. model was then used to carry out a parametric study to examine the structural behaviour of reinforced high-strength concrete slabs. The parameters under investigation include various material properties, slab boundary conditions, loading stub-column, and loading type and sequence. In addition, a tension stiffening model was approximately formulated, based on the fracture energy concept and comparison of F.E. predictions to experimental results of the tested slabs. The importance of the concrete tension stiffening behaviour was highlighted in the F.E. analysis of the slab selected.

abstract: Due to the high demand of oil and gas, offshore exploration and development are forced to explore and/or develop near areas of potential slope failure. A glide block or out-runner block is the product of a slope failure and can cause great damage on offshore structures, such as a submarine pipeline, since it can travel a long distance from its origin and carries the soil properties of the parent slide. -- To better understand the drag force generated from a glide block or out-runner block on to a suspended submarine pipeline, 11 physical tests were conducted to quantify it and are presented in this thesis. The tests were conducted in a geotechnical centrifuge located at C-CORE under submerged conditions with a centrifugal force of 30 times the Earth's gravity (i.e., N = 30) and simulated impact situations under steady state conditions and uniform velocities. The soil blocks (approximately 4.5 m high in prototype terms) were made of kaolin clay with undrained shear strengths ranged from 4 to 8 kPa. The model pipes were 6.35 and 9.52 mm in diameter, which corresponds to 0.19 and 0.29 m in prototype. The impact velocities ranged from 0.04 to 1.3 rn/s. The pipe centerline was at mid-height of the block. The shear strain rates, defined as the ratio of impact velocity to pipe diameter, in the centrifuge model are N times higher than that in the prototype, and it ranged from 4 to 137 reciprocal seconds. Hence, the test results are applicable to a wide range of field situations. A geotechnical approach was adapted, based on the results of the centrifuge tests, and a method is presented for estimating drag force for soil block impacting on submarine pipeline.

Masters thesis, Memorial University of Newfoundland.

abstract: Regioselectivity in Diels-Alder reactions is usually explained using frontier molecular orbital and/or electrostatic rationales. Steric interactions may play an important role in determining stereoselectivity. Thus, a hypothesis was suggested by the Burnell group that steric hindrance might contribute significantly to regioselectivity as well. Attempts to test this hypothesis focused on methyl-substituted para-benzoquinones. Dienes which were used had structures such that the regiochemical bias would be due to a steric factor rather than an electronic one. Previous work by the Burnell group dealt with dienes which did not show any such bias. This document deals with cyclic dienes to alleviate some prior problems. 2,6-Dimethyl-para-benzoquinone was initially used as the dienophile since many compounds found in nature have two methyl groups with a 1,3- relationship within them. Various dienes were used with this dienophile using various conditions, but unsatisfactory results required a change in the dienes to make them more stable and a change in the dienophile towards a better steric probe. Diels-Alder reactions with the new dienes and dienophiles were carried out under various conditions, still producing no satisfactory results. New dienophiles, N-phenylmaleimide and 2-methyl-Nphenylmaleimide, were used with the same dienes in an attempt to learn about the reactivity of the dienes and obtain Diels-Alder adducts. Some success was seen with these dienophiles. All of the results are summarized, along with modifications that had to be made to the Diels-Alder substrates. -- The geminal acylation reaction can be applied to many ketones and acetals. The various routes that were devised towards the synthesis of a steroid skeleton, via a double geminal acylation, as well as modifications to the original routes, are discussed. The first attempts involved the Michael addition of silyl enol ethers to α,β-unsaturated ketones to give diketones. Some success was achieved, but due to some undesired results, substrates had to be modified. These modifications led to substrates which could be used as precursors to natural products, and a route was devised for future work on this objective. The second route towards the required diketones used ozonolysis and was successful. The third and fourth routes involved alkylations, which proved to be difficult. Various conditions were tried and some showed positive results. Some new information dealing with the reactivity of alkylation substrates as well as double alkylations was discovered. Also, several substrates were more difficult to produce than anticipated. Various routes were attempted and the substrates were obtained. Some results, such as the reductive succinoylation, seen before in the Burnell group were observed with this work as well. Possible precursors to other natural molecules were obtained and routes are proposed towards such molecules.

Masters thesis, Memorial University of Newfoundland.

abstract: The banded killifish, Fundulus diaphanus, belongs to the family Fundulidae. One of two fundulids in Newfoundland (the other is the brackish water dweller, the mummichog, F. heteroclitus ), the banded killifish inhabits freshwater habitats. Located in 7 known localities across insular Newfoundland, most coastal in nature, the distribution of F. diaphanus is scattered and disjunct. The Indian Bay population record is an eastern range extension from the previous such record at Freshwater Pond on the Burin Peninsula and is the only northeast insular record of the species. While suitable habitat, generally described as the sandy or muddy shallows of freshwater lakes with abundant submerged aquatic vegetation, is fairly common, interior lakes may be unreachable due to steep river gradients. Preliminary enzymatic electrophoretic analysis indicated very little variation among the Newfoundland populations and a mainland population near the type locality. Classic morphometric analysis illustrated slight variations among populations but few consistent trends in variation. Previously designated as vulnerable (special concern) in 1989 by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), this project culminated with a re-designation of the special concern status in May 2003 after a review of the first status report compiled solely on the Newfoundland populations of the species. While the current analysis provided little evidence to treat the Newfoundland populations as a separate species or subspecies, the disjointed distribution and few confirmed localities where they occur are causes for concern and were key contributors to the species being designated as of special concern in Newfoundland.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Although the mechanical properties of cardiac muscle have been studied in various preparations, no direct measurement of isometric tension has been made at the cellular level. In this study, cultured strands of neonatal rat cardiac muscle were attached to a microgramme force transducer, using a non-traumatic method to obtain direct measurement of isometric tension. -- The isometric mechanical properties of the cultured myocardial strands were studied during spontaneous and electrically-stimulated contractions at different lengths, temperatures and rates of stimulation. Steady-state inotropic and chronotropic responses to independent manipulation of external ionic concentration of K⁺, Ca⁺⁺ and Na⁺ as well as simultaneous manipulation of Na⁺ and Ca⁺⁺ were studied. Cholinergic and adrenergic receptor response was characterized using appropriate pharmacologic agonists and antagonists. -- The basic mechanical properties observed included length-tension relationship, force-frequency response and effects of temperature. Total amount of strand stretch required to describe the complete length-tension relationship was only ± 1% of the optimum length, Lmax; suggesting that cultured strands are stiffer than adult rat papillary muscle. Repeating length-tension measurements in the same strand showed an absence of hysteresis. All other mechanical properties were similar to those observed for intact adult rat papillary muscle. Spontaneous contraction rate was influenced by K⁺ and Na⁺, while Na⁺ and Ca⁺⁺ influenced contractility. The interaction between Na⁺ and Ca⁺⁺ was very striking; the observations were consistent with the function of a sodium-calcium exchange carrier. The strand was shown to possess cholinergic muscarinic receptors, which regulate only spontaneous rate and beta-adrenergic receptors which regulate both rate and contractility. -- Thus, in the strand, functional properties of various regions of the heart are represented in a single preparation. The physiological characteristics were highly reproducible between and within strand preparations. Except for the fact that the strand is fragile and de-differentiated, it represents an accurate model for myocardial physiology and offers some important advantages for investigation of cellular physiology and the influence of ionic and drug manipulations on its basic physiology.

Masters thesis, Memorial University of Newfoundland.

abstract: Inferences in generalized linear mixed models (GLMMs) which includes count and binary data as special cases are extremely important. As it is proven to be difficult to obtain consistent and efficient estimates of the parameters (regression effects and variance of the random effects) of such models, there is a vast growing literature dealing with this important estimation problem. Among them, the method of moments (MM), Penalized quasilikelihood (PQL) and Hierarchical likelihood (HL) approaches are more familiar. It is however known that the MM approach always produces consistent estimates, whereas the PQL approach may not provide consistent estimates for all the parameters of the model. A recently proposed generalized quasilikelihood (GQL) approach has proven to be better in the sense of consistency and efficiency as compared to the MM and other improved MM (IMM) procedures. There does not, however, exist any comparative study between the GQL and the HL approaches. In this thesis, we have made a comparison between these two approaches mainly through an extensive simulation study involving the Poisson-normal mixed model. It is found that the HL approach may not produce consistent estimates for the regression effects specially when the variance of the random effects is large. In contrast, the GQL approach is found to always produce consistent estimates for all parameters of the model. These two estimation methodologies are also illustrated by analyzing a data set on the health care utilization in St. John's, Canada.

abstract: Offshore Oil and Gas producing platforms discharge produced water into the sea during production operations. This water contains toxic contaminants that are harmful to the marine environment. Produced water is treated before its discharge into the sea to reduce risks to the environment. Despite treatment, produced water contains a certain amount of contaminants that are not feasible to treat before discharge and can cause environmental concern. -- The main objective of this study is to develop decision support software with an application to characterize risk of produced water released from offshore platforms during operation. The specific objectives are: (1) development of a database for produced water contaminants; (2) integration of a chemical database with selected initial dilution and subsequent dispersion models; (3) development of a probabilistic fish growth model; ( 4) development of human health cancer and non-cancer risk assessment methodologies using probabilistic concepts; (5) development of a methodology to estimate the distribution of chemicals in the bones/shell/skeleton and flesh of a fish; and (6) application of the methodologies to a hypothetical case study. A chemical specific approach rather than total toxicity approach was employed to predict exposure concentration. Both deterministic and probabilistic hydrodynamic initial dilution models were used in this research. Monte Carlo simulations were performed in the probabilistic analysis. -- The database on chemicals was integrated into the initial dilution and dispersion models for predicting available concentration in the marine environment. This predicted environmental concentration (PEC) was converted to exposure concentration (EC) by incorporating probability of exposure and bioavailability. The concentration of contaminants in fish tissue was predicted through integrating a fish growth model and is presented in a modular form in the software. -- The risk of produced water to human health was based on the methodology of contaminated seafood ingestion. The hazard quotient (HQ) for non-carcinogens was predicted through dividing the chronic daily intake (CDI) by the reference dose (RfD). The cancer risk was predicted through multiplying the CDI by the slope factor (SF). The deterministic and probabilistic analyses for risk assessment were integrated into the software. Risk from radionuclides in produced water was performed in a separate module and integrated with the main database. -- This study has introduced a concept of chemical distribution within a fish's body and variability in the lipid contents in the fish. The change in edible parts during the exposure period has been predicted through a probabilistic fish growth model and integrated with the human health risk assessment methodologies.

abstract: Electronic waste (e-waste) as a research subject is relatively new. Studies of electronic waste have tended to focus upon what are termed 'end-of-life' issues around discarded electronic devices. What has developed in the last decade is primarily a story of rich countries dumping their unwanted electronic equipment on the unsuspecting poor in developing countries, with serious environmental and human health impacts resulting. This thesis challenges this simple narrative by examining the practices of electronics disposal at a Canadian university. This examination of disposal practices illustrates both that the simple narrative emerging from current e-waste research is problematic because not all that is discarded becomes waste, but also because mandatory electronics recycling is likely to shift negative environmental and occupational impacts related to electronics disposal from one place to another rather than ameliorate them.

abstract: The benthos of part of Long Pond, a lagoon separated by a barachois from Conception Bay, was studied quantitatively. Most of the bottom was covered by silt of high organic content. Six stations in differing substrata were sampled intensively and three communities described in the Petersen concept were recognized. The infaunistic Macoma-Mya and the epifaunistic Mytilus-Littorina communities, characterized by high biomass estimates, occupied about 5% of the study area. The infaunistic Polycirrus-Mya community covered an estimated 95% of the bottom and was characterized by a low biomass. The distribution of individual species was examined in relation to the sediment and substratum preferences correlated with particle size, organic content, compactness and depth of water were demonstrated in a number of species. The population of one station was sampled periodically over a year without detecting a gross seasonal change. The populations of individual species did fluctuate, balancing each other out over the year, and fluctuations were related to life cycles where possible. The temperature in the surface and bottom water of one station in Long Pond and in the surface water of Conception Bay followed a normal annual pattern whereas the dissolved oxygen, always near saturation, followed a pattern inverse to that of temperature. The salinity fluctuated widely in the surface water of Long Pond, especially during spring, but varied to a small extent in the bottom water and in the surface water of Conception Bay.

abstract: The preparation and characterization of a series of new π-Mn(CO)₃ and πCr (CO)₃ complexes are discussed. The benzoylcyclopentadienylmanganese tricarbonyl derivatives obtained are generally yellow in colour and melt at temperatures between 50° - 100°. The corresponding π-CR(CO)₃ complexes are orange to red in colour and melt at higher temperatures. These complexes are stable in their solid state but decompose readily in solution. -- The infrared spectra of these complexes have been studied both in CCl₄ and in Nujol mulls. A C₃v local symmetry is assumed for the M(CO)₃ moieties and the electronic effects of aromatic substituents on the ν(CO) vibrations are explained by the M.O. model. The electronic effects of the substituents on one ring are transmitted to the other vie the ketonic carbonyl group as indicated by the corresponding shifts of the ketonic ν(CO) frequencies. The lower ν(CO) frequencies observed for the π-Cr(CO)₃ complexes are mainly due to the decrease of π-electron density on the benzene ring. -- The electronic absorption bands of these complexes have been tentatively assigned on the basis of their shifts with substituent changes and by the comparison of such bands with those of related complexes. -- NMR spectral studies show that the π-character of the aromatic ring is not reduced by the electron-with-drawing effect of the Cr(CO)₃ group is that in which the Cr atom is mainly bonded to the meta and substituent positions of the monosubstituted benzene ring. -- The delocalisation of the unpaired spin in radical anions of these complexes is well illustrated by their ESR spectra. These spectra have been simulated and the spin densities calculated using McConnell’s equation. Good agreement between experimental and theoretical spin densities has been obtained. Hyperfine splitting constants show that a substantial amount of the spin density is found on the manganese atom, and the para and ortho protons of the phenyl ring. No hyperfine lines have been observed for the meta or cyclopentadienyl protons. -- The mass spectra of these complexes show a fragmentation pattern in which the CO molecules are lost first. The ability of the ionic structures to undergo intramolecular rearrangement process is facilitated by the active participation of the metallic orbitals with the π-orbitals of the ligand. The stability of the ions is dependent on the ring substituents. Where the substituent is electron donating the ions are usually stabilized and vice versa. This is consistent with the view that the electron removed during ionization belongs to a molecular orbital very largely associated with the metal atom.

abstract: This internship report discusses the impact of postmodern thought on the counselling process, and some of its implications for ethics, theory, and practice. Postmodern thought rejects the dominant modernist paradigms of empiricism and of universal codes or meta-narratives. It challenges the objectivity of the diagnosing clinician, arguing that the practitioner decides what may qualify as significant in advance of the client's particular story. Client and their stories are interpreted as Texts; client and counsellor variously share the roles of Author and Reader in a collaborative process of disclosing or creating meaning. It is argued that this is undermined in traditional practice by the notion of therapeutic distance or professional boundaries, which describe and quantify power relationships. Postmodern thought is sufficiently congruent with certain counselling models that some writers have challenged its contributions and even its novelty. In particular, it emphasizes epistemological and ethical reasons for the counselling process to be respectful, collaborative, and non-hierarchical with regard to perceived power relationships. The report goes on to discuss, from a process perspective, the author's lived experience of an ethical dilemma as a novice counsellor. The author was faced with a conflict between various ethical directives in terms of how to address the problem; in addition, actual theoretical models appeared to diverge in their interpretation of whether the challenge existed within the purview of the counsellor or outside it. Arising from this is a discussion of the dilemma as consistent with modernist codes of practice. These codes appear to have certain blind spots. While literature exists that documents and quantifies violations of professional codes, there appear to be few fora in while ethical struggles may be discussed. Gender issues may impact this as well, as traditional roles appear to limit support and dialogue. The author was not able to access appropriate guidance or discussion to address this dilemma, in counselling literature or through peer consultation; it is not clear that plans for addressing such issues had been developed, or a need identified. This may suggest a vestigial modernist theme in how counsellor evaluate, characterize, and address their own struggles. One perspective on postmodern ethics suggests that self-examination is an appropriate ethical tool and stance, as opposed to a modernist adherence to any universal moral code.

title: Liverpool shipowners: 1820-1914

abstract: For many years Britain was the most important maritime nation on Earth. Of its many significant ports Liverpool, with its world-wide connections, was among the most important. One significant element in Liverpool's maritime success were those persons who invested in tonnage at the port - the Liverpool shipowners. -- Although such did not guarantee success in any endeavour, it seems that most of the more prosperous Liverpool shipowners had something of a "leg up," or a comparative advantage, that fostered their commercial success. Most Liverpool shipowners came from the local area, where they also registered their tonnage, and were likely to buy their vessels in the local (or at least a regional) market. Barring this, tonnage purchases were often made based on commercial linkages, like the timber trade between Liverpool and British North America. In terms of the investors themselves, most would have had some form of seaward connections through careers such as mariners, or merchants. William Wheelwright, for example, grew up in a thriving port, the son of merchant shipowners. From an early age Wheelwright went to sea, eventually founding South America's first Pacific steamship service - a venture intimately connected with Liverpool which had long-standing links to South America. -- Of perhaps coequal importance to comparative advantage in shipowning was the ability to adapt to changing conditions. This was especially important in the nineteenth century, which witnessed the most profound commercial, social and technological shifts then seen. Certain firms like Wheelwright's Pacific Steam Navigation Company (PSNC) were on the very cusp of change and could be considered innovators from the start. Other shipowners, like Thos. & Jno. Brocklebank, timed adaptations much more conservatively, but were nonetheless equally adept at sensing and responding to a need for change, based on the requirements of their chosen trades. -- Neither the possession of comparative advantage, nor an ability to adapt with the times (even when such were allied to formidable business intellects), could guarantee a shipowners' success. However, the track record of Liverpool-based firms such as Brocklebanks and PSNC will demonstrate that they were at the very least powerful building blocks for the prosecution of seaward enterprise.

abstract: This thesis examines the interaction of ice and structures under simplified dynamic impact conditions, where the compliance of the structure and geometry of the ice was varied. Laboratory ice and iceberg ice conical specimens were impacted with a simply supported steel plate in a pendulum impact apparatus. The geometry of the ice cone was varied from 20 to 40 degrees and the thickness of the steel plate was varied from 0.25" to 0.75". Initial potential energy remained constant for each experiment. Forces, nominal pressures and specific energies were analyzed using response surface methodology. The compliance of the plate and cone angle of the ice specimen showed significant influence on the peak forces and nominal pressures. However, the specific energy was found to be only dependent on the compliance of the plate. Four iceberg specimens were also tested and significantly lower peak forces, nominal pressures, and specific energy was observed in the iceberg samples.

abstract: Education literature suggests that Microcomputer Based Laboratories (MBL) may indirectly enhance student physics achievement by offering several pedagogical and psychological advantages. Using data gathered from the Newfoundland Department of Education and a survey of 84 physics teachers, this exploratory research investigated the direct relationship between Microcomputer Based Laboratory use and high school physics achievement. The multiple regression analysis, which included control student factors (pre-treatment physics ability), classroom factors (teacher certification level, teacher years experience, teacher academic background, teacher microcomputer experience, extent of laboratory use, extent of instructional computer use) and school factors (school location, total school enrollment), indicated that at the present level of use, no significant relationship exists between Microcomputer Based Laboratory use and school-based or public exam achievement. The cause of this result was unclear. However, the survey data set revealed that only 55.3°/o of teachers were MBL users. This low level of use may account for the research results. Further multiple regression analysis of MBL use with classroom, school and teacher variables indicated that teacher-related factors (certification level, academic background, microcomputer experience, current instructional computer use, and current laboratory time) are significant predictors of MBL use.

Masters thesis, Memorial University of Newfoundland.

abstract: In aquaculture, the ability to predict future performance potential of eggs and larvae can help optimize hatchery production and lower overall production costs. In this study, egg batches spawned by Atlantic cod (Gadus morhua) broodstocks were collected, incubated to hatch, and the larvae reared to yolk-sac absorption. Objectives were to determine whether lipid classes, fatty acids, and amino acids could be used as indicators of egg and larval quality; to compare the utility of biochemistry and blastomere morphology as indicators of future performance potential; and to study changes in egg and larval biochemistry during ontogenetic development. Variability in several lipids and free amino acids was significantly correlated with fertilization and hatching success, particularly the phospholipids and the monosaturated fatty acid 24:1. Lipids showed conservation throughout embryo development, while free amino acids were catabolized as a primary energy source. Several blastomere morphological measures in newly fertilized eggs (eg. cell symmetry, uniformity, margins and adhesions) showed positive correlations with hatching success. These results show that both biochemistry and blastomere morphology can be useful tools for determining the performance potential of egg batches in culture, and that free amino acids serve as a primary energy source for endogenous-feeding eggs and larvae.

abstract: The research focus of this thesis is the seventeenth-century brewhouse and bakehouse structure in Ferryland, Newfoundland. The material culture, including ceramics, clay smoking pipes, and glass, and surviving architectural features are analyzed with the goal of understanding the use and occupation history of the structure. -- The results of these analyses show that this brewhouse is the same "brewhouse room" mentioned in a 1622 letter. It is also determined the structure was built early in the 1620s, and that it stood for less than two decades before being dismantled to make room for another structure. Furthermore, although the archaeology of brewhouses is not well documented or understood, comparisons with two contemporaneous brewhouses suggests that the Ferryland structure is atypical for its time, which is a direct result of the circumstances for which it was constructed. Finally, questions about when and why the brewhouse was dismantled are answered.

abstract: The purpose of the internship, conducted through the Memorial University of Newfoundland Harlow campus, was to study the British Education System and its approach to integration of Information Technology (IT) in and across the curriculum. The intention was to furnish insights that may have some application to the curricular integration of IT in Newfoundland and Labrador schools. -- Chapter One of the internship report briefly examines the present condition and role of IT in the Provincial curriculum and offers some background to the place of IT in British education and curriculum. It also outlines the objectives for the internship and the activities undertaken. -- Chapter Two consists of a critical and reflective journal of information gathered and insights gained during the internship placement and the research process. -- Chapter Three contains a summary of the research component of the internship. It examines two approaches taken to the curricular integration of Information Technology in British schools (particularly in the two schools studied): a subject-integrated or totally cross-curricular approach and a discrete subject approach. -- Interviews were conducted with department heads and lead teachers in the integration of IT at two schools of the Essex County Education Authority. A standardized list of interview questions was used. Data collection was triangulated using sources such as classroom observation and document collection. Though there was less focus on classroom observation the collection of documents was fairly extensive. Relevant and useful information was gathered from documents published by one of Britain's leading organizations in the field of educational technology, the National Council for Educational Technology, accessed through Internet searches. -- Though further research is required to quantify the results, this investigation contends that a combination of these approaches would offer the most effective method for the teaching and application of IT skills within the curriculum.
