abstract: A major production constraint for some mussel farms in Canada and elsewhere is related to 'second-set'- an accumulation of unwanted mussel seed on mussel socks. Accumulated seed may originate from primary settlement (annual settlement of mussel larvae) or secondary settlement (post-settled spat that drift) and may be severe enough to decrease growth of production mussels, reduce harvest yields, and increase production costs (extra flotation, transportation and processing costs). The objectives of the present study were to identify the biotic and abiotic factors involved in second-set dynamics through environmental and biological monitoring, as well as current husbandry observations. A multifactorial field experiment was undertaken to examine the temporal (monthly) and spatial patterns (2 sites; 3m, 6 m, 9 m depth) of larval and post-larval mussel settlement at two commercial mussel farms in Newfoundland in an attempt to understand second-set dynamics. Laboratory trials investigated mussel seed crawling behaviour under varying environmental conditions (food, temperature) with two seed sizes (5-10 mm and 15-20 mm) to explore a possible relationship with second-set accumulation. Finally, the influence of initial socking density (approximately 100, 200, 250, and 300+ mussels per 30 cm), sock deployment depth ( 4 m and 9 m), time of deployment (spring and autumn) and husbandry practices on the timing and intensity of second-set was examined. -- Results indicated that environmental conditions influenced mussel spawning times, with seed collection heaviest during August. The seasonal thermocline may have led to heavy seed collection at a depth of 9 m, however, growth of seed was less than at 3 m or 6 m. There was evidence of secondary settlement of post-settled spat (byssal drifting) which may be a source of second-set accumulation. Crawling behaviour of seed mussels was influenced by temperature and seed size, with implications for optimal socking strategies. Second-set accumulation was significantly reduced with higher initial socking densities and with depth of deployment. Fouling was heavier on low density socks. Spring deployments showed the highest sock yields and least amount of second-set accumulation after one year. Socks deployed at 9 m yielded less marketable product per 30 cm of socking than socks deployed at 4 m, yet respectable yields of 70% of gross were attained at 9 m after 1.5 years deployed. Observations of present culture practices indicated a lack  of understanding of the impact of environmental conditions and seed handling practices on sock quality. Poorly formed mussel socks had high accumulations of second-set. It is recommended that careful consideration be given to site conditions and mussel seed handling practices when socking. To avoid second-set, it is concluded that high sock quality (fullness, uniformity) be obtained, with consideration of environmental influences on mussel seed quality. For the present study, densities of250+ per 30 cm of socking at 25-27 mm shell length socked in the spring, deployed in deeper water, at or below the seasonal thermocline, worked well in reducing unwanted accumulations of second-set mussels.

type: Thesis NonPeerReviewed

abstract: This paper examines the system of informal property rights in the lobster fishery in eastern Nova Scotia. The lobster berth system is characterized by gentlemen's agreements which have been passed down through generations offish harvesters. The system was established by eighteenth century Scottish settlers with the division of land and was imposed on the marine environment when the fishing industry became prosperous. The system is founded on the principle of respect and regard for the rights of other harvesters in the system. This sense of obligation to others is what has let the system survive the decades. Many harvesters within the berth system believe the existence of such private property rights is what has enabled the lobster stocks in the area to continue to grow while other lobster stocks near-by have declined. This paper outlines the structure and division of the berth system while exploring its use as a successful conservation tool. This idea is discussed in the paper with relation to historical data on lobster landings in the surrounding areas and biological principles that influence stock productivity. The paper concludes with the argument that the system should be given more attention by Fisheries and Oceans Canada as a successful system of Fisheries Management.

abstract: Through the vehicle of personal narrative, four women from the coalmining town of Glace Bay tell their story of the closure of Cape Breton's mining industry. With the end of this traditional occupation the women, all married to coalminers, confront both a community challenge and personal challenge with the loss of the major family income. Considered within the parameters of Thomas McLaughlin's vernacular theory, the narratives point to the women's ability to articulate their own reality and to question those who hold power. The narratives reveal that contrary to seeing themselves as powerless, and notwithstanding that the course of action taken by two of the women is distinctive, each finds the courage and capacity to search for a new future. Finally, the issues of "care" as a gendered concept, and the notion of "empowerment" as a consequence of resistance are the key themes revealed through the stories collected. With the power that comes from choosing not to be a victim, the four women demonstrate that caring for and caring about others is life sustaining and profoundly productive work.

abstract: In the politics of Newfoundland, during the first ten years of Responsible Government (1855-1865), sectarianism played a very important role. From 1865 to 1869, however, during F.B.T. Carter’s first Administration, this role was lessened. Carter included Roman Catholics in his Executive Council and, with the development of the Confederation issue, sectarianism was relegated to a position of relative insignificance. In 1869, Charles Fox Bennett led his Anti-Confederate Party to an overwhelming victory at the polls. The Anti-Confederates won the election by playing on the fears of the electorate - fears of increased taxation, of military conscription, and of the loss of independence. As the result of a vigorous and exhaustive campaign, the Anti-Confederates won seventy per cent of the seats in the House of Assembly. Many of these members were inexperienced, however, and most of the leaders represented Roman Catholic Districts. -- Gradually the Confederates, realizing the impossibility at that time of effecting a union with Canada, turned again to sectarianism. Bennett’s Party, although it tried, was unable to quell the growing demand for a Protestant Government. In an attempt to divide the Protestants, Bennett condemned the Orange Society as undesirable. This was a miscalculation. Little if any, support was gained and the Orangemen were further alienated. The Government, which was often ineffective, stagnated. It was involved in a dispute with the New York, Newfoundland, London Telegraphy Company and it Act giving effect to the Washington Treaty was disallowed. In addition to these problems, rumor of misappropriations of public funds became prevalent. -- In the election of 1873, Bennett was returned to power with a majority of only three. Notwithstanding this, before the House of Assembly met, two members of the Government Party withdrew from the house and one member joined the Opposition. Bennett’s Government resigned and Carter came to power. In the election of 1874, the Protestant districts supported Carter’s Party and the Roman Catholic Districts supported Bennett. Sectarianism was again as important as it had been before Carter had come to power in 1865. Politics in Newfoundland had come full cycle.

abstract: The statistical analysis of gamma data (exponential being a special case) is quite common in many biomedical or engineering research. The existing studies deal with this type of data either in the independence or time series set up. Independence, as the name suggests implies that the data at time point 't + 1' is independent of the data at time point 't', whereas the time series set up suggests dependence in the data collected at subsequent time points. -- It may however happen in practice that one collects the gamma responses repeatedly along with a set of multi-dimensional covariates, from a large number of independent individuals over a small period of time. In this set up, it is natural that the repeated gamma responses of an individual will be correlated. It is of interest to obtain consistent and efficient estimates for the effects of the covariates on the responses after taking the longitudinal correlation into account. -- In this thesis, we study an autoregressive order 1 (AR(1)) type longitudinal gamma model consisting of a regression vector, a scale, and a longitudinal correlation parameter. The likelihood and a generalized quasilikelihood (GQL) inferences are considered for the estimation of these parameters. It is argued that the likelihood approach is extremely complicated whereas the GQL approach appears to be much simpler which also provides consistent and highly efficient estimates. This is verified through a simulation study.

abstract: In society today music use by athletes and exercise enthusiasts alike has become extremely popular, however the music selection process is typically quite personal and based often on intuition rather than any type of scientific formula. Some people say a certain type of music motivates them, some people suggest it is a certain beat or tempo and some people say it is any type of music at all. One thing that is commonly agreed upon however is that for whatever reason the music seems to make exercising more enjoyable. Thus, the present review of literature on music use during exercise is to develop an understanding of the scientific evidence as a basis for the finds that music can assist in exercise performance. The proposed benefits of using music in the exercise setting have intrigued researchers for quite some time even before portable music devices were easily accessible to the general public. There is a whole body of literature that suggests that during repetitive endurance-type activities ' motivational' music can decrease rates of perceived exertion and can lead to a positive impact on exercise performance measures. However, what has not been conclusively shown is whether listening to music has a purely psychological effect, a physiological effect, or a psychophysical effect on the participant and their responses to exercise. The actual mechanisms that are responsible for the beneficial effects music can have on exercise performance are still equivocal. Thus, future research is necessary to develop a better understanding of the effect and effect limitations of listening to music for improved exercise performance. -- Evidence indicates that music can have a psychological effect by decreasing rate of perceived exertion and increasing exercise enjoyment. However, it has yet to be concluded whether listening to music affects the physiological responses to exercise, specifically with respect to high intensity or maximal work efforts. The purpose of this study was to assess the following physiological responses: heart rate (HR), ventilatory kinetics, time to task failure (TTF) and blood lactate (BL), as well as perceived exertion; while exercising and listening to high tempo music, all set at a tempo of 130 bpm. The exercise entailed interval training at 80% of an individual's peak power output (PPO) as assessed during incremental maximal oxygen consumption (VO2max) test on a stationary bicycle. The main finding in this study was that the participant's TTF when listening to music during their exercise performance was significantly greater (p<0.05), by one minute, than when exercising without music. Exercise heart rate was not significantly affected by music, however heart rate recovery was significantly faster by 13 bpm following the music condition (p<0.05). Additionally, participants had higher blood lactate levels and they rated their perceived exertion to be lower at the same or greater workloads when listening to music (p<0.05). Lastly, a higher breathing frequency was recorded with music (p<0.05). The results demonstrate that listening to music during high intensity exercise results in physiological changes. The results also support the theory that music can contribute to prolonged exercise durations at higher intensities with lower perceived exertion.

Masters thesis, Memorial University of Newfoundland.

abstract: The primary purposes ·of this correlational descriptive study was to (a) examine the relationships between health value, health locus of control, psychological situation and the lifestyle behaviours of adolescents and (b) to explore their relevance to the practice of psychiatric-mental health nursing. A nonrandom sample of 336 adolescents completed the Health Information Survey. Findings of the investigation indicated that although students placed high value on health and demonstrated awareness of the impact of lifestyle practices on health, they engaged in detrimental lifestyle behaviours. Females, students with part time jobs and those with poor academic grades reported significantly more hazardous behaviour. Adolescents with an internal health locus of control and a positive psychological situation engaged in behaviours that were facilitative of healthy living. Students with strong beliefs in chance as reinforcement for health demonstrated the most risky lifestyle practices. Implications for mental health nursing were examined and recommendations for further nursing research were made.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: The extracts from six barley cultivars (Hordeum vulgarae L.) grown in the Canadian prairies, namely AC Metcalfe, Falcon, Phoenix, Tercel, Tyto, and Peregrine, were evaluated for their potential antioxidant, antiradical, and antiproliferative efficacies by various chemical and biological methods. Antioxidative compounds were solvent-extracted after optimizing extraction parameters (solvent composition, extraction temperature, and time) using response surface methodology (RSM). In addition, the distribution of antioxidative constituents in the barley grain was investigated by separately pearling two barley cultivars (Falcon and AC Metcalfe) into seven fractions (F1-F7) in a layer-wise fashion up to 50% of the kernel weight. Antioxidative efficacy of the layers and the remaining kernel (pearled grain) was evaluated using chemical and biological methods. Furthermore, phenolic compounds present in the six barley samples were separated into free, soluble conjugates, and insoluble-bound fractions using alkaline hydrolysis and the antioxidative potential of each of the fractions was also investigated. -- The optimum conditions for extraction of antioxidative components from barley extracts were 80% aqueous methanol, 60°C, and 40 min as determined by RSM. Total phenolic content (TPC) of whole kernel extracts ranged from 13.58 to 22.93 and 0.81 to 1.38 mg ferulic acid equivalents per gram lyophilizate and defatted material, respectively. The order of TPC was Peregrine > AC Metcalfe > Falcon > Tyto > Phoenix > Tercel. Total antioxidant capacity (TAC), as measured by Trolox equivalent antioxidant capacity (TEAC), ranged from 3.74 to 6.82 μmol Trolox equivalents per gram defatted material. Antioxidant and antiradical efficacies of barley extracts were evaluated using different assays including 2,2-diphenyl-1-picrylhydrazyl (DPPH), superoxide, oxygen radical absorbance capacity (ORACFL), hydroxyl radical averting capacity (HORACFL), and photochemiluminescence (PCL). All six barley extracts showed significant antioxidant and antiradical activities although the order of their activity changed from assay to assay. Barley extracts exhibited substantial metal chelation activity as measured by 2,2 '- bipyridyl competition assay. Evaluating the whole barley extracts using a number of model systems such as β-carotene/linoleate, bulk stripped corn oil as well as accelerated oxidation study, using Rancimat®, further revealed that the whole barley extract possessed strong antioxidant activity. Whole grain extracts exhibited strong inhibitory effects against copper-induced human LDL cholesterol oxidation as well as peroxyl and hydroxyl radical-induced DNA double strand scission. Barley extracts also exhibited substantial antiproliferative effect against growth of Caco-2 human colorectal adenocarcinoma cells in a concentration-dependent manner. -- In the second phase of the study involving fractionation, it was revealed that anti oxidative constituents were mainly located in the outer 9% (w/w) of the kernel. TPC of Falcon and AC Metcalfe fractions ranged from 0.51 to 6.26 and 0.17 to 4.16 as ferulic acid equivalents per gram defatted material. TAC, as measured by TEAC, varied from 0.45 to 60 and 0.69 to 56 μmol Trolox equivalents per gram defatted material, respectively. Antioxidant efficacy gradually diminished from the outer layers to the inner layers. In general, antioxidant efficacy determined by other methods followed a similar trend to that of TAC. -- In the last phase of the study involving hydrolysis of phenolic compounds, it was revealed that a greater proportion of antioxidative compounds were present in insoluble-bound form followed by soluble conjugate form. It was further revealed that the antioxidant and antiradical efficacies of insoluble bound phenolic compounds were the highest followed by soluble conjugates and free phenolic. The predominant phenolic acid detected in barley extracts was ferulic acid. The other phenolic acids detected were vanillic, caffeic, p-coumaric and sinapic acids.

abstract: We discuss Neyman's partial score test for homogeneity of variances in nonparametric models. We considered two data structures. First, we consider longitudinal data where the observations from each subject are generated from a nonparametric model with heteroscedastic errors. In this context, we found that the discrete wavelet transform approach used by Cai, Hurvich and Tsai (1998) does not lead to a consistent estimate of the mean response function which in turn affects the score statistic. Second, we consider longitudinal data where the observed response from each subject is assumed to be a time series that is nonstationary in mean and variance. The trend component of each series is estimated by a wavelet version of weighted least squares and the residuals are used in estimating the local variances. These estimates are used in a simulation study of the score statistic we construct for testing homoscedasticity in the longitudinal set-up. In the simulation study we examine the size and power of the test.

abstract: Studies suggest that Agoraphobia is a more complex disorder than is presented by the current DSM-111-R classification. The present study was designed to determine if degree of incapacitation by agoraphobic symptoms determines who proffers treatment to the agoraphobic as well as how the G. P. (as primary caregiver) deals with agoraphobia. Results suggest that more incapacitated agoraphobics, as compared to less incapacitated agoraphobics, are treated by a psychiatrist. Secondly, results suggest that G.P.'s treat mild cases of agoraphobia themselves. Although results did not support the hypothesis that psychiatrists would treat more incapacitated agoraphobics more often than other caregivers, results did show that, when G.P.'s did make referrals, they tend to make significantly more referrals to psychiatrists. The theoretical implications and needs of future research, based on these results, are discussed.

abstract: Currently, snow analysis for weather prediction in Canada is conducted using snow depth measurements alone. The current effort is intended to revisit this analysis using both snow depth and density measurements from snow course sites previously unused during weather prediction analysis. The purpose of this reanalysis is to produce a gridded daily Snow Water Equivalent (SWE) hindcast within the transect from the Great Lakes through Quebec and into Labrador. -- The final SWE prediction was produced by combining output from existing deterministic snow density models and developed statistical prediction models. Statistical Models were developed based on Universal Kriging (UK) interpolation technique on measured data and by considering the background fields. These fields include a number of physiographic variables and the Canadian Meteorological Centre (CMC) snow depth analysis product. -- Finally, the new product was evaluated from the calculated Root Mean Square Error (RMSE) of the predicted SWE at both validation and cross validation points, simulation vs. observation comparison, and also from a visual consistency check. The research produced a methodology for SWE prediction and daily gridded SWE product, which is a valuable attempt to improve hydrological prediction from snow melting. The average RMSE of SWE prediction was around 30-35 mm although, the validation of results were challenged by limited quantity of snow course data.

Masters thesis, Memorial University of Newfoundland.

abstract: I quantified impacts of non-indigenous Norway rats on Least Auklets breeding at Kiska Island. Little direct evidence of rat predation was found in my productivity crevices, nevertheless hundreds of rat-predated Least Auklet adults, chicks and eggs were found at the auklet colony and in rat hoards. My estimate of adult Least Auklet survival from Kiska (0.88 in 2001- 2002) was similar to values estimated by others. Yet in these years reproductive success was the lowest ever recorded (0.16 and 0.09) in the Aleutians. Norway rats foraging within the auklet colony were larger in size and showed increased reproductive activity than those foraging off the auklet colony. A simple population viability analysis, using current vital rate estimates, revealed that Least Auklets on Kiska are likely experiencing a rapid population decline. Continued monitoring and mitigation plans are required to further address the impacts of rats on auklets at Kiska.

abstract: Most of the contractile muscle protein genes have been extensively examined to understand the mechanisms controlling tissue-specific gene expression in skeletal muscle. However, very little is known at the molecular level about another major contractile muscle protein, troponin C. Furthermore, very little is known about the regulation of gene expression in cardiac muscle. In this study, slow troponin C has been examined to understand its differentiation and regulation in chicken cardiac myocytes. -- Dot blot hybridisation and restriction endonuclease analysis indicated that the chicken slow troponin C gene was present as a single copy. Although, troponio C is a very conserved protein, the conservation at the DNA level is not known. When DNA from various species was compared by Southern blot hybridisation with a quail troponin C cDNA probe, I found that quail troponin C DNA was non-homologous to DNA from other classes. -- The regulation of troponin C protein synthesis in cardiac myocyte cell cultures was examined in this study. Cultured myocyte cells were pulse-labelled with ³⁵S-methionine, at different days after plating, and the protein synthesis levels were compared by two-dimensional gel electrophoresis. At the same time, total cellular RNA was extracted and troponin C mRNA levels were examined by Northern blot analysis, using a quail troponin C cDNA probe. The results showed that mRNA accumulation closely paralleled the synthesis of troponin C, suggesting its principal mode of regulation to be transcriptional. However, the decrease in the level of troponin C polypeptide synthesis was somewhat greater than the observed decrease in the mRNA level, suggesting a possible translational control of gene expression. Furthermore, when troponin C protein synthesis levels, at different days of plating, were compared with those of actin and tropomyosin, the results indicated that unlike skeletal contractile muscle proteins, these cardiac contractile muscle proteins were not co-regulated. -- The possible association of the transcriptionally active troponin C gene of cardiac myocytes with a nuclear sub-structure called nuclear matrix was also examined. Results indicated that the transcriptionally active troponin C gene was not preferrentially enriched in the nuclear matrix fraction.

abstract: This thesis demonstrates a real time automated hybrid method for process monitoring. Motivation of this research comes from the fact that there is hardly any single techniques available which is decent enough for process fault detection and diagnosis simultaneously. Process history based methods are well known as early fault detectors but operators require complex analysis to find out the root cause of the fault. Knowledge based qualitative models are worthy for root cause analysis but mostly done in off-line fashion. Moreover, modern processes are equipped with thousands of variables and structurally they are very complex in nature. All these influences make manual diagnostic task more complicated for the operators. Therefore, there is a need for automated process monitoring tool that has good detection and diagnosis performance. -- In this work, a hybrid method based on principal component analysis (PCA) and Bayesian belief network (BBN) is described for process monitoring. PCA is very proficient as early fault detector but not for fault diagnosis. On the other hand, BBN is good for diagnosis. This hybrid method combines t he strong features of both PCA and BBN to an automated monitoring system that can detect fault early as well as diagnose the root cause precisely. Upon successful detection of fault from PCA, diagnostic information from the PCA is passed to the BBN for root cause analysis. Pearl's message passing algorithm is used for belief updating. This monitoring tool integrates prior process knowledge along with the present observed evidence processed by the multivariate statistical method to come up with the most probable explanation of process fault. Efficacy of the proposed method is verified by simulating different scenarios on a simulated dissolution tank model. The monitoring tool is also validated using industrial data from a pure terephthalic acid (PTA) plant.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Demographic trends both provincially and nationally indicate increasing life expectancy and growing numbers of older adults living with chronic disease and disability. Human resource projections predict that Canada will need to double the number of formal home care workers in order to meet future demands. This demographic change has also resulted in increasing numbers of older adults choosing to remain engaged in the workforce past the traditional age time of retirement. Research on supportive services in the community has identified the issues and challenges of homecare but little has addressed the complex interplay of economic, political, and social factors that have resulted in the health and safety challenges associated with the work provided by home support workers. Using a method of inquiry called Institutional Ethnography, this research explored the meaning of work and health and safety considerations of workers over 50 years old who are providing home support services in Newfoundland. This exploration of health and safety needs and practices, work environments, as well as policies and government systems regulating the employment of workers can be summarized into three threads that describe the everyday work of these aging home support workers: Crossing Boundaries - More Than Just a Job; Making it Work in Unhealthy and Unsafe Work Environments; and Becoming a Home Support Worker: Experience, Orientation, and Training Necessary to do the Work. The findings suggest that decision making practices to engage in risk taking behaviour that impact health and safety in the workplace are influenced by the meaning of work as well as the emotional connections and close, personal relationships with clients. It is anticipated that this research may positively influence the health and safety of aging workers in this sector. This will be achieved through the recommendations for policy and practice that emerged from this research including the development and implementation of a risk assessment tool for home support workers, clear standards on education, orientation, and training, wage parity with the acute care sector, and more clarity on title, roles, and responsibilities of home support workers.

abstract: Fuzzy Logic is relatively a recent development in the field of artificial intelligence. Since 1975, research and development in this field has had significant impact on industrial control including applications in many consumer products. A survey of the literature suggests that the majority of fuzzy control applications belong to the class of fuzzy PID-like or simply fuzzy PID controllers. Also the literature reveals that the existing design criteria require trial and error methods involving many computer simulations and need time to achieve satisfactory optimum control. This thesis presents a systematic study and analysis of fuzzy PID-type controllers with particular attention to process control. The work aims to remove the ad-hoc procedures and multi-dimensional complexity in the conventional fuzzy control designs and to present an analytical framework for the systematic design of fuzzy logic controllers. -- The work investigates different fuzzy PID control structures including the conventional Mamdani-type controller. By expressing the fuzzy rules in different forms, each PID structure is distinctly identified. The rules are written in terms of the feed back error signals of a closed-loop control system. Therefore a general fuzzy PID controller output may be produced with three-, two- or one-input rule inference. A simple analytical procedure is developed to deduce the closed form expressions for generating outputs for general fuzzy PID controllers. The analysis starts with a linear-like fuzzy controller. Nonlinear fuzzy controllers are then systematically developed. The solution algorithm has the capability to generate the closed-form expressions to the general three-input fuzzy inference. The two- and one-input inferences are obtained as special cases of the general solution. The linear-like fuzzy output is used to identify the fuzzy PID actions in a dissociated form. The design of fuzzy controllers is then treated as a two-level tuning problem. The first level tunes the nonlinear PID gains and the second le\'el tunes the linear PID gains. By assigning a minimum number of rules to each PID structure, the linear and nonlinear gains are explicitly presented. The tuning characteristics of each structure are evaluated with respect to their functional behaviours. The rule decoupled and one-input rule structures proposed in this thesis provide greater flexibility and better functional properties than the conventional fuzzy controllers. -- Non-linearity analysis is used to assess and rank the different fuzzy systems for fuzzy control. The normalized fuzzy output characteristics are identified for two-point control. Thus, a performance criterion is developed to identify the non-linearity tuning properties of the fuzzy controllers. For each fuzzy PID type, a basis for non-linearity-tuning is developed. Using the new evaluation approach, different fuzzy systems are assessed. The min-max-gravity fuzzy reasoning has shown better nonlinear properties for fuzzy control applications. An alternative nonlinear control using spline-based functions is proposed. The geometrically based nonlinear controller has better nonlinear properties for PID control. -- Linear PlD controllers are analyzed in detail. The study is narrowed to process systems whose dynamics can be roughly approximated to first-order plus dead-time plant systems. The PID analysis covers the process systems having normalized time delay ranging from zero to any higher value. The time-domain-based analysis produces new PID tuning expressions for each case. The proposed tuning rules accommodate actuator saturation limits and avoid integral wind-up during the control. Numerical studies are made for higher order processes having monotonic open-loop characteristics. With the new tuning rules better performance is observed than with other commonly available tuning methods. -- Fuzzy pm controllers are then evaluated for process control. A novel two-level tuning scheme is proposed for designing and tuning fuzzy controllers. For comparisons, three tuning methods are evaluated; (a) design based on a genetic algorithm (b) design based on a trial and error method of tuning and (c) design based on two-level tuning rules. The off-line design methods, such as genetic based tuning and trial and error based tuning, are unable to produce any improved control compared to linear PID controllers. The two-level tuning strategy uses the available linear control knowledge, and the resulting design always guarantees better performance than the linear controllers. The numerical simulations prove the new tuning method can be effectively used for any fuzzy PID controller type. Finally the two-level tuning is effectively implemented in a real time control problem. With the systematic two-level tuning, the fuzzy controllers are able to produce superior and improved performance to linear PID controllers. The design and tuning is simple and therefore the method can be extended to any process control problem.

Puberty in males occurred after one year of age. Male puberty was noted by the detection of plasma androgens during a novel testicular growth phase in which mitosis and meiosis were concurrent. Female pubertal age was plastic; maturation occurred in 1 +, 2+ and rarely 3+ animals. Culture conditions promoting 0+ growth encouraged puberty in 1 + females. Immature ovaries in primary growth stages were steroidogenic and responsive to in vitro gonadotropic stimulation. The onset of puberty was detected by a plasma 17β-estradiol peak in cortical alveolar stage females prior to vitellogenin incorporation. Mature gametes were produced within a year of the initiation of puberty in both sexes. Females became superior in body size when males underwent testicular maturation; an effect of elevated androgens on male growth was suggested. -- Hormones with reputed dual roles in growth and reproduction were administered long-term in immature females and mature males. Treatment with a gonadotropin-releasing hormone analogue (GnRH-a) failed to advance puberty in females but synchronized the onset of puberty among treated subjects relative to controls. GnRH-a did not accelerate testicular recrudescence and had no effect on growth. High levels of testosterone, whether alone or in combination with GnRH-a, suppressed growth and early gametogenesis in both sexes. A recombinant bovine growth hormone (rbGH) formulation (Posilac®) stimulated growth in males and females, reducing sex differences in body size. A positive rbGH effect on testicular mass was attributed to enhanced body size. Growth stimulation by rbGH delayed the onset of puberty in some females, presumably due to an increased utilization of energy reserves. -- Inducing triploidy was examined as a maturation deterrent. A ten minute hydrostatic pressure treatment of 7 000 psi, initiated five minutes post-sperm activation (7-12°C), is recommended to induce high percentages (92-100%) of triploid larvae. Premetamorphic growth of triploid larvae was inferior to that of diploid larvae. Later, 2+ triploid females exceeded growth rates of maturing 1+ diploid females. Triploidy minimized gonadal development but did not prevent the production of gametes in either sex. -- Yellowtail flounder demonstrated a propensity for early sexual maturation under culture conditions. Management of dietary fat levels, the therapeutic use of rbGH, and the production of triploids are proposed as measures which, alone or in combination, may help to suppress puberty in this pleuronectid flatfish.

Masters thesis, Memorial University of Newfoundland.

abstract: Perfectionism has been identified as a pervasive trait that can be found in a wide range of people. Growing research support suggests that this trait, which used to be considered one-dimensional, has multi-dimensional (i.e., negative and positive) aspects. According to Slaney, Rice, Mobley, Trippi, and Ashby (2001), setting high standards and having high orderliness qualities are the defining positive aspects of perfectionism. Discrepancy, the difference perceived between the high standards that a person sets and the actual performance that the person perceives him or herself displaying, is the defining negative aspect of perfectionism. -- This thesis studied the prevalence of multi-dimensional perfectionism in undergraduate education students and sought to determine how perfectionism related to their perceived quality of life and their GPA performance. Subjects (75 undergraduate education students) completed the Almost Perfect Scale - Revised (APS-R) questionnaire (developed in 1997 by Slaney, Mobley, Trippi, Ashby, & Johnson) and as predicted by the instrument developers, three groups were identified, namely, adaptive perfectionists, maladaptive perfectionists and non-perfectionists. -- Subjects also completed a brief World Health Organization Quality of Life questionnaire (WHOQOL-BREF), developed by the World Health Organization, to assess their perceived quality of life based on the two weeks prior to the administration of the questionnaire. It was found that the maladaptive perfectionists, as compared to adaptive perfectionists, on average, had a significantly lower perceived quality of life in three of the quality of life domains assessed, namely the Physical Health Domain, the Psychological Health Domain, and the Social Relationships Domain. It was also discovered that the Discrepancy Subscale of the APS-R had a weak negative correlation to the Physical Health Domain, the Psychological Health Domain, and the Social Relationships Domain. No other significant differences were found in perceived quality of life for any of the other multi-dimensional group comparisons and no relationships were found between the type of perfectionism displayed and the GP A scores achieved. -- The implications of these findings for both counsellors and classroom teachers are discussed and suggestions for future research are offered.

title: The paradoxes of material implication

abstract: 'Paradoxes of material implication' is a significant topic in modern symbolic and mathematical logic. Various attempts have been taken to resolve these paradoxes. Thus, a number of schools of logic have been developed in this regard. In our present paper we examine three of the main schools of modern logic which deal with these paradoxes: many valued logic, modal logic and relevance logic. Three-valued logic, which is a kind of many-valued logic, fails to show any promise in resolving these paradoxes as it adopts the entire truth table based on traditional bivalence. Five-valued logic, another kind of many-valued logic, shows some promises in resolving these paradoxes. But it destroys the system of propositional calculus and the process of judging the validity/invalidity of arguments. So it is difficult to accept this solution with such a price. Modal logic, the second approach discussed in this paper, resolves these paradoxes by introducing the device of strict implication. But the problem is that it creates some new  paradoxes, namely paradoxes of strict implication, which are analogous to the paradoxes of material implication. Hence modal logic is also not adequate. Relevance logic, however, resolves these paradoxes without creating any new paradox. It does not destroy the system of propositional calculus or the process of judging the validity/invalidity of arguments. Hence, relevance logic solves the problems of the logic of implication. Although there are some minor difficulties in relevance logic, we hope that more work in this area will resolve these problems soon, so that relevance logic will provide a fully adequate logic of implication.

Masters thesis, Memorial University of Newfoundland.

abstract: This study used a phenomenological approach drawing on van Manen's (1997) methods of inquiry in order to describe and interpret the meaning of what life is like for five women who have consented to donate a deceased relative's organs for transplantation. This study captures the meaning of this phenomenon in such a way that nurses and others who read this text, could develop new insights into the lives of these individuals, enabling them to implement strategies to better assist and support the family, and perhaps decrease barriers to organ donation. -- A thematic analysis of the participants' narrative descriptions identified five essential themes: the struggle to acknowledge the death, the positive outcome of the death, creating a living memory, buying time, and the significance of support networks in the organ donation decision. The integration of these themes revealed the essence of the experience as creating a sense of peace. These five themes and the essence of the experience are discussed in relation to the literature, followed by recommendations for future nursing practice, education, and research.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: The past decade has seen a proliferation of available predictive genetic tests. These are the result of one of the most significant scientific advances of the 21st century: the Human Genome Project. Social scientists have examined how the availability of genetic testing shapes the lived experience of at-risk people as well as subsequent health decision-making. Little attention has been paid to how the embodiment of risk is (re)shaped in light of changing genetic technologies or how experience of risk may in turn shape the development of genetics. A grounded theory approach was used to gain a fuller understanding of how 29 individuals living in a family at risk for Arrhythmogenic Right Ventricular Cardiomyopathy, in the province of Newfoundland and Labrador, construct the meaning of being at-risk prior to, during, and following genetic testing in relation to the various stages of gene discovery and test availability. Three phases of constructing meaning were identified: (1) Awakening to a New Meaning of Being At-Risk, (2) Deciphering the Meaning of Being At-Risk, and (3) Embodying a New Meaning of Being At-Risk. This study found that at-risk individuals' understandings of the meaning of being at-risk both shapes and is shaped by the "lived experience" of the genetic testing process and also impacts (and is impacted by) health care decisions. The meaning assigned to being at-risk is pragmatic, transient, and fluid. It is pragmatic in that the participants juxtapose three types of contextual dimensions (scientific knowledge, experiential knowledge, and phase of the genetic testing process) against the existing conditions, or specific factors that influence risk perception, as they assign meaning to being at-risk and make decisions, a process that is ongoing throughout the genetic testing process. The meaning assigned to risk is transient, in that as one's risk perception fluctuates so do the contextual dimensions and conditions that influence participants' choices. It is fluid, in that the meaning of being at-risk is shaped and reshaped (and the decisions change), with each new experience and coincident with the particular stage of gene discovery. These findings lead to recommendations for genetic service providers, health policy makers, and genetic scientists on best practices for health care in the context of novel gene discovery.

title: Family based spatial correlation model

abstract: In spatial data analysis, linear, count or binary responses are collected from a large sequence of (spatial) locations. This type of responses from the (spatial) locations may be influenced by certain fixed covariates associated to the location itself as well as certain invisible random effects from the members of the neighboring locations. Also the responses may be subject to certain model errors. In familial/ clustered setup, responses are collected from the members of a large number of independent families, where the pairwise responses within the family are correlated. In a spatial set up, the pairwise responses within a family of locations are correlated similar to the familial setup, but unlike in the familial setup, the responses from neighboring families will also be correlated. In this thesis, unlike in the existing studies, we develop a moving or band correlation structure that reflects the correlations for within and between families. This is done first for linear (continuous) data and then for binary responses. As far as the inference are concerned, we discuss method of moments (MM) and maximum likelihood (ML) approach for the estimation of parameters in linear mixed model setup. Because the exact likelihood estimation approach for the spatial binary models is complicated, we demonstrate how to use the generalized quasi-likelihood ( GQL) approach for such models.

abstract: This thesis re-examines the glacial landscape of the central Avalon Peninsula, Newfoundland, Canada. Specifically, it focuses on an area of moraine ridges, previous studies of which have generated conflicting interpretation of genesis and deglacial significance. For instance, it has been interpreted as a series of recessional moraines, and as a field of Rogen moraines. In light of new developments in our understanding of subglacial landscape processes, and in the available technology for mapping and analysis of digital topographic data, it is an appropriate time to re-analyse this landscape and evaluate past interpretations. -- Several methods of data acquisition were employed for this study; air photo interpretation of black and white photos at the 1:50 000 scale and colour photos at the 1:12 500 scale, field research including a review of the sedimentology of the moraine ridges, the construction of a Digital Elevation Model (OEM) for a portion of the study area, and the calculation of moraine ridge orientation within a GIS. -- The moraine ridges of the central Avalon Peninsula are considered to be classical examples of Rogen moraine. An examination of the moraine field using the 1:5000 scale digital elevation model (OEM) with an elevation resolution between 5 and 10m revealed a suite of glacial landforms, including Rogen moraine, hummocky moraine, flutes, meltwater channels and large streamlined bedrock ridges. Rogen and hummocky moraine were found in close association with each other and represent end members of a transitional landform assemblage, with neither landform overprinting the other. An examination of the intern al composition of both Rogen and hummocky moraine revealed similar sediments and structures that suggest deposition via melt-out and sediment gravity flows. The sediment within Rogen moraines and hummocky moraines was transported and deposited subglacially, and later melted out of stagnating ice. -- The timing of glacial events on the Avalon Peninsula are difficult to constrain, but the internal composition and morphology of the Rogen moraines suggest that they were formed during deglaciation. During this phase the ice centre shifted from over the central Avalon Peninsula to the head of St. Mary's Bay. Ice flow out of St. Mary's Bay was radial, with the dominant ice flow direction being in the northeastward direction, and a secondary ice flow northwards into Trinity Bay. The final deglaciation of the Avalon Peninsula is constrained by the C¹⁴ date of 10 100 +/- 250 y BP, from pollen in basal pond sediments. -- The predominant hypotheses of Rogen moraine formation found in the literature were examined in the context of the Avalon Rogen moraines, but currently it is difficult to use any of these previous developed ideas to explain the formation of Rogen moraine on the Avalon Peninsula.

abstract: The daily climatological record including snowcover water equivalent (SWE) was estimated for the Big Level Summit Plateau (BL), Gros Morne National Park, western Newfoundland, for the 1962-1999 study period. This was accomplished using widely known statistical techniques, i.e. multiple linear regression and mean ratios, linking the Big Level Autostation (1993-1999) record with the nearby low lying coastal stations records through the climate elements mentioned above. Physically based relationships were added for the snow model, which was based on the reconstructed climatological elements (temperature, wind speed and precipitation). -- The BL daily temperature record (estimated for 1946-1999) and hourly wind speed record were estimated with multiple linear regression. Precipitation was estimated using mean ratios. The estimated BL winter precipitation record was separated into snowfall and rainfall and measured snowfall at BL was corrected for wind induced undercatch. Snowcover SWE was estimated with the estimated daily precipitation record and the temperature index method, using increasing degree-day factors as the snow season progressed. Snowdrifting off the plateau and sublimation of blowing snow were also estimated using simple expressions that were a function of wind speed. -- Snowcover on BL is consistently present for long periods from year to year, although its thickness varies considerably compared with the coastal plain (BL maximum seasonal SWE varied from 110 mm to 1650 mm). The single largest factor influencing the snowcover SWE, other than the large amounts of snowfall, was found to be blowing snow sublimation, which ablates approximately 53% of the snowfall accumulation on average. Another large factor influencing snowcover SWE is snowdrifting off the plateau, accounting for approximately 10% of the average accumulated snowfall, leaving approximately 32% to be ablated by melt. The months from February to June all showed negative significant trends with respect to mean BL SWE during the study period. There were no significant linear trends in the temperature record for the period of estimation, but there was a significant linear positive trend (95% level) for the number of thawing degree-days using daily maximum temperature for the snow accumulation season (November-April) of 1.3-1.8 degree-days per year. -- An  anthropogenically induced warmer climate would lead to much thinner snowcovers existing during shorter periods, with snow seasons having reduced snowfall and increased rainfall values. The thinnest seasonal snowcovers of the recent past such as in the 1981 snow season could become above average if the IPCC climate change projections become reality.

Masters thesis, Memorial University of Newfoundland.

abstract: The purpose of this study was to develop instructional material on interpretation of photographic art. It was the developer's contention that the curriculum did not adequately allow for the achievement of art critical goals in photography, even though these were stressed as an important part of the high-school art curriculum. -- Through an instructional systems development approach, an instructional package entitled Categories of Photographs: A Guide to Interpreting Photographs was produced. A needs assessment revealed that no suitable materials existed for instruction in interpreting photographs. In defining the instructional goal, a learner analysis and concept analysis were conducted. A learning hierarchy and a set of behavioural objectives were then developed. These items served as the basis for the design and evaluation of the instructional package. -- Qualitative evaluation was carried out by expert appraisers, including teachers, content specialists, media specialists and student users. -- Quantitative evaluation consisted of two pilot tests of the materials, hereinafter referred to as the formative and summative evaluations of the product. -- The formative evaluation results indicated that the mean on the pre-test was 0%, while the post-test mean was 63.3%. An analysis of the formative evaluation results led to a number of revisions in the instructional package. -- Results on the summative evaluation showed a pre-test mean of 19.1% and a post-test mean of 69.1%. The summative evaluation led to revisions in the printed materials accompanying the package. -- In summary, the instructional package was effective in attaining the terminal objectives specified, including: increasing the time spent viewing photographs and increasing the number and types of responses to photographs. The effectiveness of the package in attaining the enabling objectives of the package appeared to be related to the abstraction levels of the categories tested, the cognitive levels of the objectives, and the academic abilities of the target population. Written test results for verbal and visual discrimination tasks conflicted with observed discriminative skills during group discussions of photographs, indicating a need for more refined experimental conditions. -- Additional refinement of the programme was recommended and carried out. The instructional programme was disseminated to Brother Rice High School, St. John's, and Mount Carmel High School, St. Mary's Bay, for final validation testing. Final packaging and diffusion of the materials will proceed upon assessment of the results of the final validation testing procedures.

abstract: This investigation was designed to determine whether or not guinea pigs and quail associated a familiar stimulus from the more salient modality with sickness. The investigation was also designed to determine whether or not increased familiarity with the more salient stimulus influenced the aversion quail and guinea pigs formed to a less salient stimulus. The animals were either familiarized or not familiarized with an experimental cue from the more salient modality; blue water for the quail and saccharin water for the guinea pigs. On the Training Day each animal was permitted access to the experimental cue along with a novel stimulus from the same modality or from a different modality; NaCl water or red water for guinea pigs and red water or HCl water for quail. The animals were then injected with a poison or neutral solution. The animals' aversion to the solutions was determined after their recovery from the injection. -- Guinea pigs did not form an aversion to familiar saccharin water, the more salient cue, but did form an aversion to a novel saccharin solution. Furthermore, quail did not form an aversion to familiar blue water, the more salient cue, but did form an aversion to a novel blue solution. The data also indicated that guinea pigs did not associate red water, the less salient cue, with sickness while familiar or novel saccharin water was present. They did, however, associate red water with sickness if tap water flavor was the only cue available from the more salient modality. Similar data collected from quail indicated that they did not associate HCl water with sickness while familiar or novel blue water was present. However, they did associate HCl water with sickness if the tap water color was the only cue available from the more salient modality.

abstract:
In my thesis, Bleached Bones Rattling: Reviving the Art of Sacramental Reading, I examine recent novels by David Adams Richards, Michael Winter, Lisa Moore, and Michael Crummey in order to flesh-out the idea of "holiness" and to show ways in which this idea has been refigured in contemporary Atlantic Canadian fiction. I begin with Richards because he is a writer who has long claimed that the holiness of human life is his central subject matter: a theme that has received harsh, cursory criticism by Christopher Armstrong and Herb Wyile (1997) and more in-depth, historical treatment by Tony Tremblay in David Adams Richards of the Miramichi (2010). Beginning with Richards and working through novels by these three other Atlantic Canadian authors (who do not necessarily share Richards' Catholic worldview), I examine varying ways in which holiness confronts a reader, calls her to responsibility, draws her out of herself into a world of others, and, through a sacramental encounter, returns that reader to herself and her world with a broader view and experience of others. -- Each chapter begins with an articulation of these stages in terms of theory and then explores the shape that theory takes in a reading of a specific novel. In chapter one, I bring the "religious" philosophy of Emmanuel Levinas and Jacques Derrida to bear on David Adams Richards' Incidents in the Life of Markus Paul (2011) in order to illuminate how a reader is called to responsibility through the "adieu" of another. In the second chapter, I examine the covenant a reader makes with a story (and the dialogic world of others therein) in a discussion that approaches Michael Winter's The Death of Donna Whalen (2010) through the literary criticism of J. Edward Chamberlin and Deborah Bowen. In the third chapter, I give shape to a reader's journey out from herself- her own ego- in looking at Lisa Moore's February (2009), Gregory Wolfe's essay "Stalking the Spirit," and the philosophy of Paul Ricoeur. And in the fourth and final chapter, I examine the sacramental nature of the reading experience by comparing the theoretical views of Daniel Coleman with those of Richard Kearney and "tasting" the substantiation of these views in Michael Crummey's Galore (2009). -- My aim throughout this work is to construct a new theoretical language, out of an old religious language, in which to house the idea of holiness and to give it new critical shape in contemporary literary studies. In doing so, I demonstrate how holiness, despite its religious history and connotations, is more than an "idea" but a "real" life-giving and humanizing presence in fiction that can be encountered by all readers. -- This encounter, far from being idealistic or utopian, is a messy, combative affair which I depict as Jacob wrestling the angel: a reader grappling with that which is beyond her. In doing so, I demonstrate what Jean-Louis Chretien, in Hand to Hand: Listening to the Work of Art (2003), describes as the "intimate violence" of this encounter: this covenant. I do this by confronting theories of holiness with their "twin" forms in specific novels, forcing these theories to wrestle with their fictive figurations-like the left-handed and right-handed twins of Mother Earth in Iroquoisian myth- in order to see how stories can wound and bless these theories and transfigure them into a new theory of holiness. -- Ultimately, I argue that reading allows for a continuing substantiation of holiness-an
empathetic sense of human worth-in the life of a reader. Such readings, as I demonstrate in my encounters with novels by Richards, Winter, Moore, and Crummey, open a reader to be both wounded and blessed by the humanity of others, allowing that reader imaginative opportunities to become ever more human herself. This involves more than "recovering the human in an ideological age," to riff on the subtitle of Gregory Wolfe's recent book Beauty Will Save the World (2011). What I propose is are-imagination of what it can mean to be human if we see our fellow humans as, in some way, holy and irreplaceable: utterly unique and of infinite value. -- Central to my thesis is the belief that stories wrestle from us such re-imaginations: of ourselves and our worlds. And we too leave our mark on stories in our interpretations of them. Stories, after all, can be catalysts for imaginative awakenings in the life of a reader, and these awakenings-these re-imaginations-are, ultimately, the prophetic outworking of sacramental readings: Ezekiel's valley of dry bones rattling, beginning to rise up.

abstract: Numerical analysis was used to characterize 113 Vibrio and five Aeromonas strains. The Vibrio were comprised of 33 type and reference strains, and 80 strains isolated from the seasonally-cold coastal waters of Newfoundland. The sources of the regional cold-ocean strains were brown alga and scallops. A property shared by all of the cold-ocean strains, and only some of the type and reference strains, was an ability to grow at 4°C. Several conditions, which might affect the outcome of the study, were investigated. Based on the results obtained it was decided to use, routinely, an incubation temperature of 20°C. Tests for growth on organic compounds as sole sources of carbon and energy were incubated for three weeks there than the more common six day period. The treatment of weak positive results as weak positive, positive, or negative was investigated also. It was decided that the general conclusions reached in the study would not be significantly altered by the interpretation of weak positive results. -- Strains were divided into two categories. These were made up of strains that tested positive for the arginine dihydrolase pathway and those that tested negative. All of the arginine dihydrolase-positive regional strains were from alga and most were identified as V. splendidus biovar I, a species of Vibrio known to grow at 4°C. One arginine dihydrolase-positive strain resembled V. diazotrophicus or V. aestuarianus. Of the arginine dihydrolase-negative strains, most of the strains that could be identified were designated V. marinus, although these strains also resembled the fish pathogen V. ordalii. The former is known to grow at 4°C and the latter is not. A small number of arginine dihydrolase-negative strains were identified as V. cyclosites and C. ordalii. Four clusters of regional strains could not be identified. These may represent new species or biovarieties. These strains, all of which grew at 4°C, clustered separately from some type strains, none of which grew at this temperature. It was concluded that some of the cold-ocean strains belonged to known species of Vibrio, mostly ones that can grow at cold-ocean temperatures. However, not all strains could be identified and further studies may show these to be new species or biovarieties of Vibrio.

title: Immunogenicity of drug resistant HIV

abstract: Antiretroviral drug resistance and cytotoxic T lymphocyte (CTL) escape are considered to be major obstacles to effective control of human immunodeficiency virus (HIV). To investigate the possibility of combining drug and immune-based selective pressures to combat the emergence and transmission of HIV, we studied the effect of drug resistance mutations on CTL recognition of HIV -1 pol epitopes. Several drug resistance mutations sustained or even enhanced antigenicity and immunogenicity of HIV -1 epitopes. Thus, drug resistant HIV is susceptible to immune selective pressure which could be applied to combat transmission or emergence of drug resistance and enhance the immune response against HIV. We also observed instances of activation of CTL against a control self-peptide derived from interferon-gamma inducible protein (IP)-30 following in vitro stimulation with an HIV protease (PR) peptide. We found that activation of IP-30-specific CTL resulted from T cell cross-reactivity between the two peptides and indicates that HIV PR 76-84 peptide is a heteroclitic peptide variant (i.e. more immunogenic variant) of the IP-30 signal peptide, which may have implications for immune memory and autoimmunity.

abstract: There is a tendency to equate the word "hurricane" with the tropical regions of the world. Few recognize the danger and risks that occur when a tropical cyclone reaches colder subtropical waters and undergoes extratropical transition. Atlantic Canada, particularly the island of Newfoundland, is most at risk from extratropical transitions. The circumstances, location and dynamics of extratropical transitions in the North Atlantic have not been extensively studied. Consequently, forecasters continue to call approaching storms "hurricanes," when most are extratropical cyclones by the time they reach Atlantic Canada. -- Extratropical transitions in the North Atlantic between 1991 and 2011 were analyzed to determine if the frequency, magnitude and intensity of potential shifts can be calculated for the purpose of more accurate forecasting and the benefit of public awareness, safety management, and preparedness. Between 1991 and 2011, 324 tropical cyclones formed, and 121 of these underwent extratropical transition, a mean of 5.76 per year. Extratropical transitions occurred more frequently in the middle of the Hurricane Season, with the peak transition month being September when 43.3% of cyclones transitioned. The largest percentage of cyclones began extratropical transition between 30 and 39.9°N, and 50.4% of cyclones completed their transition between 40 to 49.9°N. Of the 121 storms, 49.6% weakened after completing extratropical transition; 21.5% had little or no re-intensification after transition; and 29.2% re-intensified. Identifying if a cyclone will re-intensify after transition is a necessity. Cyclones have emerged from transition stronger than the tropical state, bringing widespread disaster to areas in the storms' path. -- Newfoundland, in particular, has suffered devastating impacts from extratropical transition, notably Igor in 2010. Igor impacted Newfoundland as a Category 1 hybrid system which was still undergoing extratropical transition. Twenty-seven cyclones directly impacted Newfoundland between 1991 and 2011, 8% of the total for the entire North Atlantic. A third of cyclones qualified as Cape Verde Cyclones, which are cyclones that form in the deep tropics close to the Cape Verde Islands off the west coast of Africa. Cape Verde Cyclones usually have enough time to build up strength as they cross the Atlantic and frequently reach "major hurricane" status. Igor was an example of a classic Cape Verde Cyclone. Flooding was a severe problem, destroying property and roads and isolating communities. Total damages were estimated to be at least $110 million CAD with some values reaching as high as $200 miIlion CAD.

abstract: Math reform in schools has been the subject of considerable debate for decades. The National Council of Teachers of Mathematics (NCTM) defines the reform's goal as to promote a paradigm shift away from traditional approaches involving rote memorization and skill training (drill) toward problem-solving, reasoning and communication as the basis of deeper conceptual understanding. Despite significant efforts in reform implementation, a tension between the old and new approaches still exists and presents an important issue for mathematics educators. -- This thesis documents narratives of eight mathematics teachers selected from the Eastern School District of St. John's, Newfoundland about how they deal with mathematics reform and what are their accomplishments, shortages and needs. It presents an interpretive qualitative study using in-depth interviews and the constant comparison method of data analysis. -- This study reveals that teachers have a good understanding of the key ideas underlying reform but many still feel uncomfortable and somewhat disarmed when facing numerous challenges and lack of support which might force them to return to traditional practices. The implications of this study for the education system are discussed.

abstract: Known in the vernacular as the Tidal Wave, the November 18th, 1929 tsunami that struck the Burin Peninsula of Newfoundland is a pivotal point in the history of the region and its people. Stories of the event circulate in oral tradition, in narrative and song, as well as being recorded by the media and the popular press. Tidal Wave narratives offer insight into how its survivors remember and describe their communities, families and themselves before and after the disaster. The rapid technological advances of the twentieth century have distanced today's generation from the lifestyle and social structure that their grandparents experienced. The similarities and differences between the oral and written accounts of the Tidal Wave afford the opportunity to explore how individual and community or regional identities are constructed. Collective identity is conveyed through marketing strategies and public displays. Individual identity is relayed through gender and social roles within the larger social structures of the family and the community. Stories and images of the Tidal Wave have been commodified and sold as representative of Newfoundland culture. Narratives of the Tidal Wave continue to exist in oral tradition as legend and as part of family and regional folklore.

Masters thesis, Memorial University of Newfoundland.

abstract: The purpose of this study was to analyze the heuristic strategies utilized by grade seven and eight students in attempting to solve novel mathematical problems. Also investigated was the sequencing of heuristic strategies and core procedures. – Twenty-four students of both sexes equally divided into three ability groups – high, medium and low – were involved in the study. Each student was presented with a sheet of cardboard and a marker as well as two problems to solve. These were presented one at a time and consisted of one algebra and one geometry. In addition, for one of these problems physical materials were provided. A maximum of fifteen minutes per problem was permitted. The students were videotaped individually as they used the “thinking-aloud” technique while attempting to solve the problems. – Heuristic strategies and core procedures were recorded using a coding system based on that developed by Blake (1976). The coding procedure had an intercoder reliability of .87 and a sequencing reliability of .77. From the coded protocols, an analysis of the heuristic strategies was conducted. To analyze the sequencing of patterns of heuristics a graphical representation was devised.

abstract: In Canada, over 23,000 women are diagnosed with breast cancer annually with approximately 19% of these women under the age of 50. Younger women diagnosed with breast cancer often have inferior survival rates and higher recurrence rates compared to older women. The purpose of this research was to bring attention to younger women's experiences with distress from the time they are informed of a breast detected abnormality requiring biopsy until a diagnosis is confirmed. The study focused on women 50 years of age or younger and who were pre-menopausal. -- The breast cancer discourse often focuses on women's ability or inability to adapt or cope with a diagnosis of breast cancer. Feminist epistemologies of standpoint theories provided a theoretical framework to guide this study to understand the structural organization of the health care system that may induce or exacerbate distress from younger women's point of view. Principles of Feminist  Participatory Action Research were applied as part of the methodology to engage young women in a dialogue to share their personal experiences and make recommendations for the health care system to be more responsive to younger women's breast health needs. -- The uniqueness of this qualitative study is that 14 younger women were interviewed prospectively prior and after diagnosis. Research methods included 28 in-depth interviews and two focus groups; participants also kept journals. Data was analyzed using a voice centered relational method. Three themes are discussed as part of the findings: (1) The Unexpected: Finding of a Breast Problem and the Beginning of Anticipatory Illness- Loss of Innocence, The Vulnerability of Living with the Unknown, The 'Being' in Being a Patient and Mobilizing Support While Caring for Others. (2) The Journey from the other Side- I don't have Breast Cancer. (3) The Journey from the Other Side- I have breast cancer. -- The research undertaken brings awareness to the experiences of younger women undergoing a breast cancer investigation who have defined distress from their perspective with the hope that the deli very of health care policy and services, including psychosocial services, at time of breast biopsy and diagnosis can be improved.

abstract: Recruiting and retaining medical personnel to rural communities is a human resource challenge. Studies suggest that the spouse's experiences and perceptions of a rural community are among the most influential factors in a physician's decision to remain in or leave a rural practice. -- In this explorative study, thirteen interviews were conducted with spouses of rural physicians to gain a better understanding of spousal concerns and experiences regarding rural living. Specifically, this study describes the factors that both directly and indirectly influence spousal contentment and explores how these factors contribute toward recruitment and retention of physicians to rural practice locations. Participants in this study included the spouses of general practitioners and family physicians practicing and living in rural communities (population 10,000 or less) on the Burin and Bonavista Peninsulas. -- The findings indicate physician workload and community integration have the greatest direct influence on spousal contentment, while licensure, remuneration, and physician demand indirectly influence spousal contentment and ultimately practice location decisions. Overall, contentment of both physicians and their spouses was found to be crucial for recruitment and retention therefore policies need to be integrated to serve both parties with their best interest in mind.

abstract: This thesis aims to study the fresh and hardened properties of self-consolidating concrete (SCC) produced with metakaolin. The first stage of the study was to identify the most favourable replacement of cement with metakaolin by varying the metakaolin content from 0 to 25% in SCC. Typical tests for SCC were conducted on the fresh and hardened properties for all mixtures. Based on these test results, the optimum metakaolin percentage was chosen and the effect of the mixture design on SCC was studied. Using the same tests as the first stage, the second stage varied the coarse-to-fine aggregate (C/F) ratio, coarse aggregate size, binder amount, and air content to optimize SCC containing metakaolin. The third stage of the program was to study the effect of metakaolin and mixture design on the shear capacity and cracking behaviour on full-scale sec beams. The results indicated that 20% metakaolin replacement gave the optimal flowability, passing ability, segregation resistance, 28- and 90- compressive strengths, Flexural Strength (FS), Splitting Tensile Strength (STS) and Modulus of Elasticity (ME). However, the addition of metakaolin, increased the viscosity of the mixture and the high range water reducer (HRWR) demand. Varying the mixture design showed, using a lower C/F ratio of 0. 7, increasing the coarse aggregate size to 20 mm, increasing the total binder content to 500 kg/m³, and using air entrainment up to 7%, all helped to improve the flowability, viscosity, and passing ability of SCC. However, when using a lower C/F ratio of 0.7, the HRWR demand increased for all mixtures, while all other design parameters reduced the HRWR demand. Examining the mechanical properties, it was seen that using either a lower C/F ratio of 0.7 or increasing the binder content to 500 kg/m³  improved the compressive strength as well as the strength development, flexural strength, splitting tensile strength and the modulus of elasticity. While, increasing the coarse aggregate size to 20 mm or increasing the air entrainment to 7% resulted in a reduction in the compressive strengths and strength development, flexural strength, splitting tensile strength and the modulus of elasticity. Using a larger C/F ratio of 1.2, was shown to decrease the normalized shear strength, while increasing the post diagonal cracking resistance in normal-strength sec beams, although, in high-strength sec beams, there was no significant variation. In addition, increasing the coarse aggregate size to 20 mm, increased the normalized shear strength and post diagonal cracking resistance in normal-strength sec beams, and showed no affect in high-strength sec beams.

Masters thesis, Memorial University of Newfoundland.

abstract: Habitat selection is a multi-scaled phenomenon. Selection depends on the scales perceived by organisms, while our ability to detect selection depends on analytical scale. Traditional studies of habitat selection have been limited by the use of discrete, arbitrary scales, because a quantitative basis has not existed for evaluating how animals perceive the availability of habitat. I developed new approaches based on common geostatistical and spatial analyses that use continua to represent multi-scaled winter habitat selection by caribou (Rangifer tarandus) from the perspective of the organisms, letting their responses define the scales of analysis. Caribou responded most strongly at the feeding area level, at distances up to 13 km, and at scales of patchiness of about 1 ha. Although habitat selection among levels of behaviour was hierarchical, caribou selected habitat variables across overlapping scale domains, suggesting that limiting factors were not hierarchically constrained. My results implicate habitat heterogeneity as an underlying cause of multi-scaled habitat selection.

abstract: Not many women realise that what they learn from the practical day-to-day knowledge of childbirth also contains their society's ideology and beliefs, which later have a wider impact on them in giving meaning to their experience of childbirth, and the way they see themselves as women. In a traditional society such as Indonesia, women have both traditional and modem knowledge. Both categories of knowledge can give women choices about how they want to shape their childbirth experience. -- In this thesis, we will learn about six Indonesian women's experiences of first childbirth that are widely influenced by their socio-cultural circumstances as well as by their religion, Islam. The experiences of these women include their desire to have children, their feelings throughout the pregnancy, their plans for the birth and their choice of professionals who are going to help them throughout the pregnancy. Throughout pregnancy, these women were also acutely aware of the traditional beliefs and customs about pregnancy, as well as their own feelings and experience about labour. Through a case study method, this study also covers the influence of other people (husband, family and friends) in pregnancy and traces the nature of the knowledge that they transfer to these women. Within the competing sources of knowledge that is given to them, these women learn and build up their understanding about their pregnancy as well as how they see themselves in their new positions as mothers. In this study, we will be able to learn that the meaning of pregnancy varies among women. It can be oppressive, challenging, and liberating or even a combination of these. I provide my account of their experiences based on feminist theory that agrees that it is not women's biological capacity as reproducers that makes childbirth oppressive to women but the socio-cultural situation that has conditioned them to oppression. -- By acknowledging what these women have learned and that impact of that knowledge on them, society will be able to create a better situation for women that will enable them to learn about childbirth in ways that will help them to make informed choices and to mature as a result of the experience.

abstract: The aim of this study was to explore the interrelationship between economic development and the impact of industrialization on Newfoundland's construction workers. My starting assumption was that the economic and political had a strong impact on the social. A qualitative case study methodology was used wherein three mega-projects were subjected to examinations to determine what impact the quest for economic development and its resulting industrialization had on workers. A combination of archival research, newspaper and other documentary research was backed up by interviews of by informants, particularly in the third case study. -- The empirical work focused on explaining the structure of Newfoundland's economy and the impact of the complex intertwinings of the social, political and economic environment on Newfoundland workers. The key shuctura1 dynamics to understanding the impacts of economic development were found to be the degree and effectiveness of employer support for good labour relations (which often played out in initial support for a union site), the state of the economy, and the role of the government in the project. As the case studies demonstrate, structural properties of class and gender were crucial to understanding the ways in which economic development influenced workers and workplaces. -- This study is also one of the first to provide an intimate portrait of the life of construction workers in Newfoundland. Examining the daily life on three different construction projects allows the study to determine change over time; and also provides a lens through which we can examine gender relations, occupational health and safety, and labour relations on the projects. This thesis, in providing a theoretically informed discussion of detailed case study material, contributes towards the debate on the role of the government in economic development. Because two of three case studies were legislated within a new set of legal parameters, by special collective bargaining provisions as special projects, the study may also aid our understanding of the relationship between economic development, collective bargaining and the role of the government. It also informs the debate on the role of workers/unions and employers in fostering better labour relations.

abstract: The aim of this research was to develop a synthetic route to produce 5,6-fused-l-aza-2-oxobicycloalkane amino acids. Geminal acylation of a ketone or its acetal provides ready access to a 2,2-disubstituted 1,3-cyclopentanedione derivative. Double geminal acylation of diketones with long acyclic tethers between the carbonyls is envisaged as a core strategy for the development of synthetic access to tethered peptidomimetics. The focus of this research was to develop a route to 5,6-fused-1-aza-2-oxobicycloalkane amino acids which are β-turn peptidomimetics, with carbon-based bridgehead substituents. Geminal acylation of the acetal derived from hexadeca-1,15-diene-5,12-dione gave the 1,3-cyclopentanedione 52 in 29% yield along with numerous interesting side-products. A successful route to form lactams via Beckmann rearrangement was established. The development of this synthetic route, including the elucidation of the structures of side-products, is discussed in detail.

abstract: The retention of front-line workers is an ongoing challenge for public child welfare organizations. The objective of this study is to better understand whether and to what degree supervision influences a worker's decision to look for another job. This study, part of a larger cross sectional workforce retention study, involves a survey of caseworkers and front line supervisors in thirteen (13) county-based social services organizations in a northeastern state. The approach used for this study is participatory research. Two supervisory factors were identified, knowledge and support. The logistic regression analysis comparing the effects of supervision on a respondent's decision to look for another job was significant for both factors: supervisor knowledge and supervisor support. -- Action theory, emphasizing the relationship between two kinds of theory: espoused theory and theories-in-use, provide the framework for this study, which considers the congruence between what child welfare organizations espouse and what actual behavior demonstrates in the area of supervision. The results of this study provide empirical support for the effect of supervisor behavior on a worker's decision to look for another job.

abstract: The beetle fauna of old growth and previously harvested balsam fir forests of western Newfoundland was investigated from 1992 to 1994. Pitfall traps were placed in replicate sites of 40 year old, 60 year old and old growth forest stands of dry and moist fir forests. Over 20,000 beetles comprising 122 species were collected. Principle components analysis separated old growth sites from previously cut sites and dry forest sites from moist sites. Out of 122 species collected, 70 species were found in abundances of 5 or more individuals in total over the entire sampling period. Six of these species were found only in old growth forest stands, 6 were significantly more abundant in those stands, while 10 species were significantly more abundant in the previously cut stands. Four species were significantly more abundant in the 40 year old stands, while 2 species were significantly more abundant in the old growth and 60 year old stands, indicating possible recovery to old growth abundances 60 years after forest harvesting for some species. -- The old growth stands contained more and larger fallen logs, more mosses and Lycopodium, and a more open canopy. The difference in beetle composition between the old growth and previously cut sites may be a result of differences in the amount of suitable microhabitat, such as fallen logs and the low dispersal ability of many old growth forest species. The results of the study would suggest that forest harvesting rotations of 60 years may cause the extinction of some beetle species which are specialists in old growth forests.
