title: Parent-child discussions of crime

abstract: When children witness or experience criminal events, the first people they go to are generally their parents. No one is privy to these conversations, and consequently, very little is known about their specific content. Research has shown that merely saying something in children's presence may be sufficient for children to incorporate information into their event recall (Pezdek & Roe, 1997), which is particularly problematic when the information incorporated is incorrect. Once children's event memory has been changed, regardless of the skill of an interviewer, children may be unable to provide accurate reports (Thompson, Clarke-Stewart, & Lepore, 1997). It is important then to assess parent-child interactions about events. In the present study, seven- to ten-year-old children watched one of two videos of a theft and talked about the video with either a parent or a trained interviewer. In Part I of the study, the types of questions parents asked and children's incorporation of parent-suggested information into their recall was assessed. Results showed that: (a) parents relied heavily on yes/no and direct questions, (b) children made errors of commission in response to parent questions, (c) very few parents asked leading or misleading questions, (d) all children incorporated correct information suggested by parents, and (e) few children incorporated incorrect information suggested by parents. In Part II, parent-child interviews were compared to interviews conducted with a second group of children by trained interviewers, after watching the same videos. Results showed that (a) children provided more information in response to trained interviewers, (b) there was no difference in overall or peripheral accuracy, but children were more accurate in their provision of central information when interviewed by a trained interviewer as opposed to a parent. In Part II, the influence of an early parent-child interview on children's recall in later interviews with a trained interviewer was also assessed. Half of the children were interviewed an additional time immediately following the video and all children were interviewed one week later. Parent interviews aided the accuracy of children's peripheral recall. The results imply that the influence of simple one-time parent-child discussions on seven- to ten-year-olds recall for events recently witnessed by these children may be minimal, particularly when there has been no opportunity for extended or repeated discussions.

type: Thesis NonPeerReviewed

abstract: This thesis describes a theoretical investigation of magnetic systems based on corner-sharing tetrahedra in the pyrochlore lattice. Er₂Ti₂O₇ shows magnetic ordering at low temperatures. In order to understand the origin of this magnetic behavior, we have investigated the crystal structure and have found the possible ground states using group theoretical approaches. We investigate nearest neighbour exchange interactions on the pyrochlore lattice. The pyrochlore structure consists of vertex-sharing tetrahedra; there are two different types (A and B) of tetrahedra that differ by their orientation within the pyrochlore lattice. Each edge of each tetrahedron corresponds to a term in the exchange interaction. Our model assumes that the pyrochlore space group symmetry is broken such that exchange constants on the A tetrahedra are different than those on the B tetrahedra. The Hamiltonian describing exchange interactions on the A tetrahedra has an exact solution. We include the exchange interactions on the B tetrahedra using perturbation theory with periodic boundary conditions. Possible ground states for selected values of exchange interaction are calculated.

abstract: This doctoral research is an account of the emotional experiences encountered by interns while teaching mathematics in the socio-cultural context of the junior and senior high school classrooms. Also, it describes similarities and differences existing between the emotional experiences of interns with different goal orientations. What kind of emotional experiences do interns encounter wile teaching mathematics? What similarities and differences exist between the emotional experiences of interns with different goal orientations? -- Basic qualitative research and case study research approaches were used to examine the complex relations between interns’ emotions, goals, and actions. Data were collected using interviews, surveys, diaries, and classroom observations, as these generate in depth descriptions of interns’ emotional experiences encountered while teaching mathematics, as well as attributed causes, thoughts, and perceived effects. -- The case study portrayed the internship as a place where a mastery oriented intern can experience both pleasant and unpleasant emotions. It showed that unpleasant and pleasant emotions were experienced sporadically at the beginning of the internship. The case study revealed how unpleasant emotions and to use them to perfect teaching practices. -- Mastery oriented and performance approach interns presented similarities in attributed causes of pleasant emotions, such as: students understand math, do their homework, or are engaged in classroom activities. However, for mastery oriented interns, pleasant emotions relate to students’ understanding, while for performance approach interns, pleasant emotions related to their increased desire to appear talented at teaching. Performance avoidance interns attribute causes of pleasant emotions to getting positive feedback from supervisors and students, or to not encountering significant classroom disruptions. -- Thoughts appearing in conjunction with unpleasant emotions show performance approach interns’ affinity to attribute the causes to students’ inappropriate behaviour or lack of attention. While experiencing unpleasant emotions, performance avoidance interns’ thoughts run towards their inability to control the class, to questioning their choice of a career, and to thinking about avoiding and even leaving the teaching profession.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Micellar electrokinetic chromatography (MEKC) is a form of capillary electrophoresis (CE) that uses a surfactant at a concentration higher than its critical micelle concentration for the separation of analytes. The choice of surfactant can be key to a successful analysis. This is first demonstrated via the application of a relatively volatile surfactant (ammonium perfluorooctanoate - APFOA) for the analysis of yV-methylcarbamates by MEKC - electrospray ionization - mass spectrometry (MEKC-ESI-MS), circumventing the well-known problem of signal suppression in MS by non-volatile anionic surfactants. An experimental design type of approach is used to optimize the separation voltage, the nebulizer pressure, and the concentrations of APFOA and isopropanol. -- The type of surfactant can also have a major impact on the quality of the separation, and surfactants (or more generally, pseudostationary phases - PSPs) are often characterized via linear solvation energy relationships (LSERs). This makes it possible to calculate their system constants, which reflect differences in the properties of the micellar and the aqueous phase with respect to cohesiveness, polarizability, dipolarity, and hydrogen bond accepting and donating ability. This methodology was applied to characterize anionic dimeric surfactants based upon the type (hydrophobic, hydrophilic, fluorinated) and length of the spacer connecting the two amphiphilic moieties. Dimeric surfactants that had spacers with one to six ethylene groups, one to four ethoxy groups, and one to three C₂F₄ groups were synthesized. The system constants of dimeric surfactants with hydrophobic spacers do not depend on the length of the spacer. Compared to sodium dodecylsulfate (SDS), the most commonly used PSP in MEKC, they are slightly more cohesive, interact better with polarizable compounds, and are somewhat better hydrogen bond acceptors and worse hydrogen bond donors, while there is no difference in dipolarity. Dimeric surfactants with hydrophilic spacers differ from those with hydrophobic spacers in the sense that there is a modest increase in the hydrogen bond accepting ability and a decrease in the hydrogen bond donating ability as the number of ethoxy groups in the spacer increases, while other system constants are the same. Dimeric surfactants with fluorinated spacers have similar selectivity to dimeric surfactants with hydrophobic spacers, although they are somewhat less polarizable, and less able to act as hydrogen bond acceptors. The results are explained in terms of the interphase model of retention, whereby selectivity differences between surfactants are largely shaped by differences in solvation properties of the interphase region and the bulk solution. Although these dimeric surfactants do not show unusual selectivity compared to the wide variety of PSPs already evaluated for MEKC, it is demonstrated that small selectivity differences can be taken advantage of to fine-tune separations.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: I investigated bottom-up climate-mediated control of population of auklets (Aethia Cristatella, A. pusilla, and A. pygmaea) in the Bering Sea over two decades of environmental variability, broadly, this thesis comprises two parts: 1) examining the relationships between chick diet and survival in the context of large-scale climate and oceanographic patterns; and 2) using stable-isotope analysis to infer foraging patterns throughout the annual cycle of different age classes of auklets, using information on chick diet and local oceanography to interpret the results. -- I found that large-scale oceanographic patterns during the winter and spring in the North Pacific were related to auklet productivity the following breeding season. I hypothesized bottom-up control of auklet productivity through food limitation, but found that chick meal composition throughout the Aleutian Islands did not differ among years or sites. Auklets’ main prey, Neocalanus spp. Copepods were most prevalent in chick diets when local sea-surface temperature (SST) during the breeding season was around 4.5 ± 1.0°C, but that outside this range, the proportion of biomass represented by Neocalanus copepods declined rapidly. There was significant overlap among Least, Crested, and Whiskered Auklets in the composition of chick meals, suggesting little trophic segregation. -- Using information on moulting patterns, I found that stable-isotope ratios in the innermost primary feather (grown during incubation) indicated a shift by adult auklets to a more productive foraging location (e.g., oceanic fronts), presumably as a mechanism for reducing their own maintenance costs during chick rearing. I then found that, among three auklet colonies in the Aleutian Islands, there were no differences among sites of years in the foraging patterns of Least Auklets during pre-breeding (breast feathers), incubation (primary 1), or post-breeding (primary 10). There appeared to be some level of ecological segregation between adult Least and Crested Auklets at Gareloi Island. -- Together, these results also indicate that local factors, such as introduced Norway rats (Rattus norvegicus) at Kiska Island, are important factors in populations’ demography, and that demographic responses are not solely driven by bottom-up processes. Future studies should focus on the winter ecology and movements of auklets.

Masters thesis, Memorial University of Newfoundland.

abstract:
Neural precursor cell (NPC) proliferation and apoptosis are key regulatory aspects of mammalian nervous system development. Although recent studies suggested these two processes to be interrelated, the molecular mechanisms behind this remain undefined. Here I show that myeloid cell leukemia-1 (Mcl-1), a Bcl-2 family member that is essential for the survival of NPCs also reduces NPC proliferation and promotes their terminal mitosis. I found that within 48 hours of in utero electroporating Mcl-1 in E13.5 mouse embryonic brains, the majority of NPCs transfected with Mcl-1 have migrated into the post mitotic conical plate, whereas control transfected NPCs
are still within the pro liferating ventricular/subventricular zones. Analysis of proliferation by proliferating cell nuclear antigen (PCNA) immunohistochemistry revealed a 2-fold reduction in proliferating NPCs in the Mcl-1 treated brains. Immunohistochemistry for Tbrl, a marker for newborn neurons, showed a 50% increase in differentiated neurons in Mcl-1 treated brains. BrdU birthdating demonstrated that Mcl-1 overexpression results in a greater cohort of newborn neurons. Furthermore, Mcl-1 transfected NPCs gave rise to neurons in the deeper layers of the cortex than control transfected NPCs confirming an earlier birthdate. Similarly, transfection of Mcl-1 in NPCs in vitro promotes cell cycle exit. I showed that Mcl-1 interacts with key cell cycle regulators in NPCs, namely PCNA and Cdk1/Cyclin B1 complex. In addition, I found an increase in Cdk inhibitor p27Kip1 protein, a key promoter of cell cycle exit with Mcl-1 overexpression and a concomitant decrease in p27Kip1 in Mcl-1 conditional knockout NPCs, suggesting that Mcl-1 may modulate p27Kip1 protein to promote NPC differentiation. Finally I showed that p27Kip1 is required for Mcl-1 mediated NPC cell cycle exit, suggesting that Mcl-1 regulates NPC cell cycle through p27Kip1 activity. In summary, these results identify a novel function for Mcl-1 in promoting terminal mitosis of NPCs by influencing the cell cycle regulatory machinery.

abstract: In the present study a linear boundary value solution for the ship wave radiation problem at zero speed and at forward speed is obtained in the time domain. Fluid velocity potentials due to the non-impulsive input and constant input are obtained by solving the boundary value problem using source strengths (indirect method). The singularities in the Rankine source of the transit free surface Green function were dealt with by the use of the well known Hess-Smith method. The panel method was validated by the application of the classical problem of the hemisphere and extended to the application of the Wigley Hull for the radiation problems at forward speed. The computed response functions added-mass and damping coefficients, along with the wave resistances were compared with published results. The final part of this thesis discusses some of the limitations of the Green function and suggest numerous ways to avoid these intrinsic errors.

abstract: In modern VLSI design, extensive research has shown that automated analog layout generation is a nontrivial process in the analog and mixed-signal circuitry synthesis. The main contribution of this thesis is successful development of a method, which is able to handle complex multi-group symmetry, substrate sharing, and other topological constraints in the analog and mixed-signal layout placement design using transitive closure graph (TCG) representation. -- This thesis proposes a set of symmetric-feasible conditions, which can guarantee symmetric placement of sensitive cells with respect to one or multiple symmetry axes for reduction of parasitic mismatch and thermal gradients. A new contour-based packing scheme has been developed with the time complexity of O(p･n･lgn), where p is the number of the symmetry groups and n is the number of the placed cells. Furthermore, a set of perturbation operations is devised with the time complexity of O(n), where n is the number of the placed cells, in order to generate a random symmetric-feasible TCG state from an existing one. The experimental results show the effectiveness and superiority of this proposed scheme compared to the other state-of-the-art placement algorithms for analog layout designs. -- In addition, the proposed method is able to handle the substrate sharing constraints which require the devices to be placed adjacent to share a common substrate in order to decrease the effect of substrate coupling. To the best of the author's knowledge, this is the first proposed approach to handle the substrate sharing constraints based on topological representations. Other topological constraints such as relationship, abutment and alignment can also be handled by our method. -- The thesis first presents a brief introduction to the analog design, including electronic design automation, analog synthesis, and analog placement. The previous important works, which intended to solve the analog placement problem, are thoroughly surveyed and analyzed. Secondly the TCG-based method to handle complex analog layout constraints such as symmetry, substrate sharing and other requirements is detailed and the corresponding algorithm complexity is analyzed. Finally the performance of the proposed method is compared with the other alternatives and the conclusions are drawn.

abstract: The solvent effect on optical and electronic properties of conjugated polymers has recently been paid much attention. Conjugated polymers have many potential industrial applications, for example, they are used in optoelectronic devices such as organic light emitting diodes, field effect transistors, solar cells, and many others. In some cases it was shown that the usage of an appropriate solvent can lead to higher efficiency in organic solar cells. In this work, we investigate the solvent effect on the electronic structure properties of some conjugated polymers, basically, fluorene and carbazole oligomers, and some benzodithiophene based co-monomers. Also solvent effect on some transport properties of benzodithiophene based co-monomers are investigated. The energy levels, band gaps, and dipole moments are obtained with density functional theory (DFT). The B3LYP, hybrid exchange-correlation functional, and the polarized split-valance basis set, 6-31G*, are used to determine optimized ground state structures of the above mentioned molecular systems. The time-dependant DFT is employed to calculate their excited state properties. For solvent effect we make use of the polarizable continuum model. Two solvents, chloroform and methanol are employed for fluorene and carbazole oligomers. Four solvents, chlorobenzene and o-dichlorobenzene, in addition to chloroform and methanol, are used for benzodithiophene based compounds. The results show that the presence of a solvent lowers the HOMO and LUMO energy levels, and increases or decreases the HOMO-LUMO energy gap depending on the chemical system, and decreases the lowest excitation energy. The magnitude of ground state electronic dipole moment of the systems is increased in solutions. The solvent effect on the reorganization energy depends on the system studied. The calculated values for the various quantities are compared with the experimental ones whenever possible.

abstract: Transshipment is the practice of sharing common resources among supply chain members in order to mitigate the risks of uncertain demands. The main theme of this thesis is the transshipment problem in decentralized supply chains. The members of decentralized supply chains are self-interested agents who do not necessarily consider the efficiency of the whole chain, and need contracts that specify the details of their cooperation. We provide a systematic overview of coordinating contracts in supply chains before focusing on three specific questions concerning the decentralized transshipment problem. -- The first problem addressed by this thesis is to find coordinating transshipment contracts for supply chains with two agents. We propose a transshipment contract that always coordinates the general two-agent supply chains. This mechanism relies on an implicit pricing mechanism, i.e. agents initially agree on a formula for setting the transshipment prices, and once quantity decisions have been made and prior to the realization of demands, they fix the transshipment prices. -- The second problem is to find coordinating contracts with a pricing mechanism in supply chains with more than two agents. We propose a mechanism for deriving the transshipment prices based on the coordinating allocation rule introduced by Anupindi et al. (2001). With the transshipment prices being set, the agents are free to match their residuals based on their individual preferences. It has been shown that with the transshipment prices derived from the proposed mechanism, the optimum transshipment patterns are always pair-wise stable, i.e. there are no pairs of agents that can be jointly better off by unilaterally deviating from the optimum transshipment patterns. The third problem pertains to the effects of cooperation costs on transshipment games. Despite its practical relevance, the issue of cooperation costs has not been addressed in the supply chain contracting literature thus far. We study the cooperative transshipment game with symmetric newsvendors having normally distributed independent demands. We provide characterization of optimal individual quantities, the maximum expected profits, and individual allocations for these games. These results, though interesting by themselves, are only a point of departure for studying the games with cooperation costs. We provide conditions for stability (non-emptiness of the  core) of these games under two governance network structures. i.e. clique and hub.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract:
In bioturbated reservoir facies, ichnology is integral to reservoir characterization. Ichnological analysis of a reservoir facies and subsequent classification into ichnofabrics or ichnofacies allows for characterization of reservoir properties. Bioturbation can redistribute grains and cause sorting or mixing, this physical modification of the primary sedimentary fabric causes changes to porosity, and permeability in reservoir facies. In highly bioturbated reservoir facies, bioturbation can be the first order control on petrophysical properties. -- Petroleum geologists are primarily concerned with the effect that bioturbation has on the petrophysical properties of a reservoir facies, rather than the details of ichnotaxonomic identification. The proposed bioturbation style categories do not require in-depth knowledge of ichnology. The categories can easily be applied to facies and core analysis for incorporation into reservoir models. The action of bioturbators can be considered in terms of: 1) sediment mixing; 2) sediment cleaning; 3) sediment packing; 4) pipe-work building strategies; 5) combination sediment cleaning and packing; and 6) combination pipe-work building and sediment packing. Sediment packing and sediment mixing styles commonly reduce porosity/permeability, while sediment cleaning bioturbation style enhances porosity/permeability. Pipe-work building and combination bioturbation styles are highly dependent on the lithological contrast between burrow fill, and enclosing substrate. The use of bioturbation style categories, and the classification of trace fossils into these categories may be more user-friendly for reservoir geologists than existing paleoenvironmentally-driven ichnofacies or ichnofabric analysis. -- While categorization of bioturbation style is a useful tool in reservoir characterization, lateral variations in reservoir quality and heterogeneity of ichnofacies or ichnofabric must be incorporated into geological models in order to predict fluid flow in bioturbated facies at the inter-well scale. Ichnological analysis allows insight into variations in sedimentation rate, hydrodynamic energy (erosive currents), substrate consistency, length of colonization window, and community succession (tiering and cross-cutting relationships). This ichnological dataset means that inferences regarding both physical and chemical processes acting at the time of bioturbation can be made. -- There is inherent ichnological variability within most bioturbated beds. The lateral variability, or patchiness of the ichnofabrics studied were not found to be related to proximity to the paleo-shoreline in the three wave-dominated depositional systems. Instead, the most critical factor appears to be the sediment accumulation style. Slow continuous deposition was found to produce complex and highly patchy ichnofabrics, whereas rapid, episodic, event bed deposition was found to be associated with the most uniform development of ichnofabric. -- Autocylic and allocyclic interpretations can be postulated for bioturbated key stratigraphic surfaces in siliciclastic shallow marine settings. A case study illustrating the need for careful ichnological analysis has been undertaken as part of this thesis, and focuses on Thalassinoides, and its validity as an indicator for key stratigraphic surfaces. Thalassinoides is easily identified in core and outcrop, has a pipe-work bioturbation style, and colonizes a variety of substrates including softground and firmground (Glossifungites ichnofacies) substrates. The Glossifungites ichnofacies is commonly found in association with relative sea level change, but alternative autocyclically-generated processes should be considered. With careful ichnological investigation, realistic palaeoenvironmental and
sequence stratigraphic interpretations can be made by objective consideration of both autocyclic and allocyclic processes. -- This research uses bioturbated shallow marine case studies to create a first order understanding of likely reservoir quality, reservoir heterogeneity, and interpretation of candidate key sequence stratigraphic surfaces. These concepts are an integral part of reservoir to basin scale models of hydrocarbon reservoirs. With an improved, integrated, understanding of what bioturbating organisms do to sediment, ichnology can continue to grow as an important component of reservoir characterization studies, and petroleum geology in general.

abstract: Pulse-to-pulse coherent Doppler sonar is a promising tool for measuring near-bed turbulence and sediment transport in energetic environments such as the bottom boundary layer. However, turbulence measurements are limited by measurement noise caused by pulse-to-pulse backscatter decorrelation, and by the requirement to resolve velocity ambiguity in the presence of measurement noise. Existing methods address these limitations separately. This thesis presents an algorithm for velocity estimation that optimally fuses multi-frequency and multi-transducer measurements to simultaneously suppress noise and resolve velocity ambiguity. Data fusion is achieved using a probabilistic approach, whereby measurements are combined numerically to derive a velocity likelihood function evaluated on a discrete grid. Maximum A Posteriori (MAP) estimation is used to produce a velocity time series in which measurement noise is suppressed while high frequency turbulent fluctuations are retained. The algorithm is validated with numerical simulations of a multi-frequency coherent Doppler sonar. Results are presented from a turbulent round jet and a towing tank grid turbulence experiment where both velocity ambiguity and backscatter decorrelation were present. Time series and spectra from MAP velocity estimation are compared to those obtained with conventional Doppler signal processing. In addition to robustly resolving velocity ambiguity, the MAP velocity estimator is shown to lower the noise floor in measured turbulence spectra.

abstract: Individuals with chronic low back pain (CLBP) have altered activations patterns of the anterior trunk musculature when performing the hollowing maneuver. Clinically it has been reported that there is a subgroup of individuals with CLBP who demonstrate primitive reflexes (PR). The main objective of this study was to determine if orienting the head and extremities to positions which mimic PR patterns would alter the activation patterns of the anterior trunk musculature during the performance of the hollowing maneuver. This question was investigated by comparing electromyographical (EMG) activity of bilateral rectus abdominis (RA), external oblique (EO), and the lower abdominal stabilizers (LAS) of 11 individuals with CLBP and present PR to a group of 9 healthy individuals during the execution of the hollowing maneuver in 7 different positions. Using magnitude based inferences it is likely (<75%) that the control group had a higher ratio of left LAS: left RA activation in the following positions: supine, Asymptomatic Tonic Neck Reflex (ATNR) left and right, cervical rotation to the right and cervical extension positions. A higher ratio of right LAS: right RA was detected in the supine and ATNR right position. It was also clinically likely (>75%)that the CLBP) group had higher activation of the left RA in the supine, ATNR left and right, cervical position for the right RA. When the data from both groups were compiled the LAS illustrated significantly (p<0.05) less activation when in the contralateral ATNR position compared to all other positions except cervical rotation to the right on the left LAS. Right EO activation was significantly higher (p<0.05) in the left ATNR position compared to the supine ATNR right and cervical flexion position. The results indicate that individuals with CLBP and present PR have altered activation patterns during the hollowing maneuver compared to a health control group and that altering body position can diminish the differences between groups. It is also indicated that position change alone can change the activation levels of the LAS and EO in both groups.

abstract: Private career colleges have been around for more than one hundred (100) years and play an important role in Canadian post secondary education. It is only recently that researchers are attempting to know more about the composition of private colleges and type of students who enroll in the programs they offer. The purpose of this study was to explore students’ decision making process towards private career college programs in Canada and to investigate factors that affect their decision. This study used a qualitative research methodology involving 16 randomly selected students from a private career college in Toronto, Ontario. Analyses of the data collected through semi-structured interviews using open ended questions revealed that a majority of the students in this private career college were female and selected post secondary education programs to enhance their skills in order to meet job market requirements. They shared distinct characteristics, and self identified as having evaluated available alternatives when making college selection and were satisfied with the outcome of their decisions.

abstract: This thesis examines the religious life of the French colony of Plaisance (Placentia) in Newfoundland during the seventeenth and eighteenth centuries. The secular clergy who served the colony during its early years were replaced in 1689 by a group of friars from the Franciscan Récollet province of Saint-Denis (Paris). The Récollets of Saint-Denis were, in turn, replaced by Récollets from Brittany in 1701. Both groups of friars engaged in missionary work in Plaisance and the surrounding areas and often found themselves dealing with problems such as conflict with the secular authorities of the colony, a lack of religious participation by the inhabitants, insufficient or inconsistent funding, an inability to control religious passing through Plaisance aboard ships, and problems of recruitment within their own ranks. -- The religious history of French Newfoundland is examined using a multiplicity of approaches including a study of the documentary evidence surrounding the tangible forms of religious life in Plaisance, a demographic examination of the population background in Plaisance, and an examination of the religious history surrounding the French colonies. Further, the economic and social realities of a populace with close ties to the fishery and the impact of life in a military establishment impinged upon the religious and spiritual life in the communities. -- The first portion of this thesis deals with life prior to 1689, and includes a study of the migratory religious systems of the colony. Links between the fishery and the religious community are established, as are such factors as Protestantism in the North American colonies, connections between religious life and economic means, religious life elsewhere in New France, and the roles of the governors in establishing the religious atmosphere in Plaisance. -- The third through to the fifth chapters examine the establishment and development of the Récollet mission from 1689 to 1701, a significant evolution in the history of the community. The introduction of the Récollets from St.-Denis shifted the social mechanisms within the colony. In attempting to understand the vagaries of the roles played by the monks in Plaisance, an understanding of the nature of the Gallican Church from whence these monks emerged is necessary, as is a study of the political and military events which enveloped their daily lives. -- The shift of jurisdiction to the Récollets of Brittany in 1701 is discussed in chapter six, with emphasis on dynamics between the two provinces of Franciscans and the distinctive ways in which the respective groups of friars made their niches. The Récollets from Brittany appear to have had a more numerous presence in the community and seem to have been of a similar social background to the inhabitants of Plaisance. -- This history of religion in French Newfoundland ends with the movement of the community of Plaisance to Ile Royale (Cape Breton) in 1714. The Récollets of Britanny were instrumental in assisting the secular authorities and the colonists with both the journey and the reestablishment of the colony in what was later to be known as Louisbourg. An understanding of the religious life of the French during their formative years in Newfoundland yields a more fruitful insight into the religious histories of Newfoundland, Ile Royale and New France.

Masters thesis, Memorial University of Newfoundland.

abstract: The purpose of this study was to investigate the inter-relationships among reading comprehension, students' perceptions of themselves (both globally and scholastically), and metacognitive awareness (specifically, view of reading task, knowledge of reading strategies and perceptions of self as a reader). -- Forty-five female students and forty-five male students were identified from four grade six classrooms at an elementary school school in Marystown. [Six groups of fifteen, were assigned, according to gender and percentile ranking in the Comprehension sub-test of the Gates-McGinitie Reading Test, Level D, Form 1]. Subjects were randomly selected from three categories of ability until equal numbers of highly-skilled (scoring between the 58th and 99th percentile in the Gates-McGinitie), moderately skilled (scoring between the 44th and 54th percentile in the Gates-McGinitie) and less skilled (scoring between the 7th and 27th percentile on the Gates-McGinitie) male and female readers. Students were interviewed orally using the Thomas Attitude and Awareness Inventory to determine their level of metacognitive awareness with respect to their attitudes and perceptions about the reading task, their knowledge of the reading task and reading strategies, and their perceptions of themselves as readers. Interviews were tape-recorded, transcribed and scored for "meaningful" answers. Numerical scores were tabulated for each of the three sections of the inventory. The Harter Self-Perception Profile for Children was also then administered to each student in order to tap each child's judgements of his/her competency in five different domains. Four domains included: scholastic competence, social acceptance, physical appearance and behavioural conduct; as well, a global perception of their worth or esteem as a person, was measured. Numerical scores were tabulated for each question in each domain. Scoring resulted in a total of six sub-scale means which defined the child's profile. -- The results obtained were submitted to correlational analysis to determine the relationships of the selected variables to reading comprehension as well as the relationships among these variables. At the .01 level of confidence, statistical analysis revealed relationships existed between: -- skill in reading and perceptions of scholastic competency, -- skill in reading and reading attitude, -- skill in reading and knowledge of reading strategy, -- skill in reading and perceptions of self as reader, -- scholastic competency and reading attitude, -- scholastic competency and knowledge of reading strategies, -- scholastic competency and global self-concept, and -- reading attitude and knowledge of reading strategies. -- At the .05 level of confidence, statistical analysis revealed relationships existed between: -- gender and knowledge of reading strategies; and -- perception of self as reader and knowledge of reading strategies. -- Teaching methods which allow interactive dialogues, explanations, modelling, and practice time that help students learn reading strategies in a variety of reading texts within positive classroom climates (i.e., those which are conducive to students' chance-taking and decision-making) appear to be critical educational implications of this study. As well, providing opportunities for the development of an enjoyment of reading and visualization comprehension strategies for male readers are important considerations. -- Further research studies are recommended using more accurate instrumentation and sophisticated correlational designs which extend the scope of this investigation to include the influence of parental attitudes and beliefs on children's perceptions and value of the reading task and attributions for success, (or failure). Such studies should also include rural and urban communities within provincial and cross-cultural settings.

abstract: Antibody combining sites represent mirror images of their antigen epitopes. Anti-idiotypic antibodies specific for the combining site for the first antibody could exhibit similar tridimentional structure to that of the original epitope. With this background, internal image anti-idiotypic antibodies have been tested by numerous groups of investigators in several biological systems. Some of these were without any specific biological activity but others such as anti-insulin, anti-acetylcholine and anti-beta adrenergic receptor agonists have been found to have agonistic activity at the level of their specific receptors. -- Graves' Disease is an autoimmune disorder involving the thyroid gland. Its etiological agent is thought to be an antibody with agonistic properties at the level of the thyroid stimulating hormone (TSH) receptor.  The receptor itself has been thought to be the antigen responsible for the production of this antibody. However, considering the above mentioned premises, it is possible to speculate that the thyroid stimulating antibody of Graves' Disease could, at least in some cases, be an anti-TSH anti-idiotypic antibody. -- This work was designed to investigate the possibility of producing anti-TSH anti-idiotypic antibodies and to test their biological activities. Anti-TSH antibodies were raised by injecting rats with highly purified TSH. This first antibody was later purified and used in the production of anti-idiotypic antibodies this time in rabbits. The activity of the anti-TSH anti-idiotypic antibodies was tested in experiments in vitro. It was demonstrated that the antibodies produced were true agonists at the TSH receptor level. They were capable of interfering with the binding of TSH to its receptor, activating adenylate cyclase, promoting adenylate cyclase mediated cellular processes and recognizing the TSH receptor protein in thyroid plasma membrane protein blots. -- A second group of experiments explored the activity of anti-idiotypic antibodies directed to the individual subunits of the TSH molecule. The information obtained appears to favour different requirements for receptor binding and postbinding events. Antibodies with activity specific for each of the subunits of TSH were individually capable of binding to thyroid plasma membranes. On the contrary, there was absolute requirement for the participation of both antibodies for the activation of adenylate cyclase. -- The third part of this work explores the influence that TSH may have on the synthesis and turnover of its receptor. These experiments were possible thanks to a detection system that benefits from the capacity of anti-TSH in the regulation of receptor synthesis and turnover. TSH accelerates the synthesis and prolongs the half life of its own receptor. -- In summary this work has demonstrated that it is possible to raise anti-TSH anti-idiotypic antibodies. The antibodies produced had agonistic effects at the level of the TSH receptor. It was also shown that these antibodies can be useful tools in the detection of receptor proteins and in the investigation of the hormone-receptor interaction.

abstract: Research into the relocation of the elderly from the community to long term care has been well documented as a major life change for this population, one that may have many physical, social, and cognitive implications. Some research documents the positive implications such as an increased sense of security, increased social contacts, and better physical well being. Contrary to this, other research suggests negative implications such as anxiety, depression, and loss of independence. --  Grounded theory methodology was used to explore the process of relocation and subsequent adjustment to a nursing home among elderly adults four to six months after admission.   Six females and three males were interviewed and data analysis was conducted to determine the common themes that existed in the individuals' experiences of their adjustment. --  Three main stages of relocation were identified: preparing for the move, moving to the nursing home, and settling in on a more permanent basis. Within each of these three stages a number of phases were identified and the interrelationships between these phases allowed the researcher to identify similarities and differences among the participants with regards to their adjustment to the relocation to the nursing home. --  The findings of this study emphasized the variation in the psychological adjustment to nursing home life including factors that helped or hindered the adjustment process. The results of this study supported the literature in the identification of interventions to help ease this transition. The research also identified new insights into the process of relocation and how adjustment may be experienced by members of this population.

abstract: This thesis explores cultural discourse among Jews of Upper Nazareth in Galilee. The discourse is provoked by the fact that they have to share their living space, even their country - the Jewish state - with Arabs who are also citizens of this state. Although the discourse is ostensibly about Jewish-Arab relations, it is conducted internally between the Jews and, the thesis will show, is even largely about relations between Jews, not between Jew and Arab. -- The construction of Upper Nazareth was begun in 1956; its site was deliberately chosen so as to be on a hill immediately overlooking the ancient Arab city of Nazareth, Christian and Moslem, and the thesis first looks, in detail, at the ideological issues that come to the fore among the pioneering Jews who build, develop, and settle Upper Nazareth. -- As political and economic relations between Jews and Arabs of the two Nazareths changed (with Arabs coming to live in Upper Nazareth), so, among the Jews, the difference between Us (Jews) and Them (Arabs), instead of being self-evident, became  ambiguous. Here the thesis concentrates on the changing constructions of cultural Self among the Jews of Upper Nazareth. Our analysis demonstrates how the constituting of Self is inextricably entwined with its reciprocals - the constituting Other (Arab) and also with Jewish otherness in Upper Nazareth. -- The analysis concludes by showing how questions about Self and Other are seen, by the Jews of Upper Nazareth themselves, also to raise questions concerning apparent contradictions between two founding principles of the State of Israel: Zionism and democracy. The questions are, in large part, intractable. Yet in response to them, and to changing demographic profiles, the Jews of Upper Nazareth, so aggressively secular in the early years of the town, increasingly make use of the ancient Jewish religious tradition, although without necessarily any concomitant religiosity.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: This thesis presents the results of a study of the ecology of fish communities of lakes and reservoirs in Labrador, Canada. The first  objective of the thesis was to evaluate the relevance and implications of a bi-dimensional framework to integrate spatially-explicit energy flows in consumer feeding ecology and food web structure. Second objective was to assess whether spatially-explicit bi-dimensional feeding ecologies and food web structures can improve the assessment of mercury (Hg) bioaccumulation in fish. A bi-dimensional framework consists in the integration of horizontal (spatially-explicit) and vertical (trophic) energy flows. This approach is demonstrated in comparative studies of fish populations and communities from four pristine lakes. Horizontal energy flows here distinguished between littoral and pelagic carbon contributions to fish consumers in lakes, quantified by variations in stable isotope  ratios of carbon in fish tissue. Vertical energy flows described variations in fish trophic position quantified by variations in stable isotope ratios of nitrogen. Comparing life-stage and among-lake patterns of trophic position and littoral-pelagic resource use in four fish species demonstrated that bi-dimensional feeding strategies are determined by species ontogeny and ecosystem characteristics. Comparisons of lake-specific bi-dimensional food web structures estimated from community averages of fish trophic position and littoral-pelagic  foraging demonstrated that spatially-explicit community organization is related to consumer species composition, to primary productivity constraints and to physical ecosystem structure. Applied to the understanding of Hg bioaccumulation, a bi-dimensional framework  integrated spatial influences on Hg exposure and trophic transfers in aquatic ecosystems and improved predictions of fish Hg concentrations. Horizontal energy flows in this case further distinguished between allochthonous-autochthonous carbon contributions to primary producer-consumer. A bi-dimensional approach revealed that aquatic ecosystems with longer food chains, greater assimilation of autochthonous carbon at lower trophic levels and greater reliance on littoral carbon by fish, reach greater Hg contamination. The influence of littoral-pelagic resource use on fish Hg levels varied with the type and size of prey consumed across habitat boundaries. Autecological types distinguish consumers bi-dimensional feeding ecologies as shaped mainly by ontogeny (Quis type), by ecosystem features (Ubi type) or both (Aequivocus type). This classification provided species-specific distinctions for the importance of biological and environmental determinants of Hg bioaccumulation in fish. A bi-dimensional framework provides a solid conceptual basis for spatially-explicit  cological understanding that can improve the assessment of environmental issues.

abstract: There are several aspects of research in DNA analysis. This thesis is an exploration of four different areas of DNA analysis that use Combinatorics and its applications. First, Levenshtein introduced the idea of Levenshtein Distance. For two strings, Levenshtein Distance is the number of operations (insertions, deletions and substitutions) required to transform one string into the other. An application of Levenshtein Distance includes creation of large sets of synthetic tissue identification that provided error detection and correction. The second area of DNA analysis using Combinatorics is the application of Graph Theory. Two methods of sequencing technique, fragmentation (overlap) method and sequencing by hybridization, both of which use Graph Theory, are studied. The third area of DNA analysis that we study is sequence comparison. Dynamic programming is used to effectively pair up two sequences. A heuristic method of searching sequence alignment such as FASTA is discussed. The final area of DNA analysis studied is the efficient selection of unique oligonucleotide (oligo) from a database containing large DNA or protein sequences. With the large size of database, an effective approach to find unique oligos is required. In this thesis, the Brute-Force method and the filtration methods for the selection of unique oligos, and parallelization of these methods to save some time in searching for unique oligos, are studied. The Brute-Force and filtration methods give us accurate results but they may take a long time. We attempt a new approach, which gives us less accurate results over much improved searching time.

Masters thesis, Memorial University of Newfoundland.

abstract: A phenomenological research method was used to explore the perspectives of Memorial University of Newfoundland students with reading/writing related learning disabilities regarding their senior high school experiences. In particular, their opinions regarding the effectiveness of the Pathways framework were examined. Six individuals participated in the study. All: had successfully completed the provincial high school program; were diagnosed with reading/writing related learning disabilities; received services via the Pathways framework during high school; and pursued studies at Memorial University of Newfoundland. Participants articulated their senior high school experiences including their academic and personal struggles. They also relayed their perspectives and recommendations regarding the Pathways framework. Through qualitative research analysis, themes emerged in the following areas:  -- Understanding of the Pathways Framework: Overall, participants lacked a thorough understanding of the framework. -- Inclusion: Despite the challenges faced by many participants in the regular classroom, overall, participants supported inclusion of students with learning disabilities. -- Meeting Students' Needs: Numerous participants reported issues/problems with services/supports received during high school. -- Stigma: Participants' perspectives on the severity of stigma associated with having a learning disability varied significantly. -- Parental support/support of significant person(s): Participants identified that the support of a significant person was instrumental to personal successes. -- Self-awareness: Overall, participants effectively communicated personal strengths and needs.  However, some participants struggled to identify and describe specific diagnoses. -- Work ethic/determination: The majority of participants expressed that, in order to overcome the challenges posed by their learning disabilities, strong work ethics were developed. -- Adjusting to Memorial University: Participants articulated that academic challenges were a normal part of the transition process from high school to university schooling. As such, these challenges should not be discouraging to students with learning disabilities. -- Advice/Recommendations: Participants had varying advice for students with learning disabilities intending to pursue university studies. As well, participants made numerous recommendations regarding improving the services provided to high school students with learning disabilities. --  The research findings increase our understanding of the high school experiences of students with reading/writing related learning disabilities. The findings clearly indicate that, according to students with reading/writing related learning disabilities, there is much room for improvement in terms of the provision of services at the high school level. As well, the findings identify factors that increase the chances of academic success for students with learning disabilities.

Masters thesis, Memorial University of Newfoundland.

abstract: During excavations in 1996, Dr. Tim Baumann, a professor at the University of Missouri - St. Louis, uncovered a historic nineteenth-century pottery factory under the Brown Masonic Lodge in Arrow Rock, Missouri. Following summertime excavations of the site between 1996 and 2001, a sub-floor of a bottleneck kiln was exposed, along with fire boxes, waster dumps, the foundation of a workshop, storage shed, and features used for the storage of glaze, and thousands of ceramic artefacts. The artefacts, features and structures found were used primarily between the mid 1800s and the late 1870s. Historical documents including industrial censuses suggest that the Arrow Rock Pottery was a substantial industry with employed people producing primarily functional utilitarian pottery. The assemblage of artefacts collected from the site was dominated by ceramic sherds that can be divided into two categories: functional vessels used domestically for preparation or food storage and the kiln furniture or utensils used in the bottleneck kiln to support the vessels during the firing procedure. --  This thesis explores a sample of ceramic artefacts found at the Caldwell Pottery factory. The purpose of this study is to understand what is "folk pottery" in the southern states of the United States of America? Who made such ceramic wares? What does it look like, judging by archaeological, historic and ethnographic information? The analysis of the artefacts not only quantified the frequency of forms but allowed them to be classified into two categories, vessels and kiln implements. Reconstructions of these goods are presented as an example of the type of ceramics produced at the Caldwell pottery factory. This research explores history in an attempt to understand how folk pottery, which was once a fixture in American pantries, was replaced by glassware as both the consumer and business changed in America as it progressed into the nineteenth century. Through the combination of a literature, ethnoarchaeological research as an apprentice folk potter, and the analysis of 700 ceramic artefacts the objectives of the research was achieved. This typological analysis is the first of its kind in the State of Missouri.

abstract: The present thesis deals with analysis and numerical simulation of a new class of wake flows created by combined recti-linear (translational) and rotational oscillation of a cylinder placed in a steady uniform flow. The flow is incompressible and two-dimensional, and recti-linear and rotational oscillations are harmonic. The instantaneous translation and rotation start at the same moment and the development of the flow is studied in a coordinate frame which moves with the cylinder but does not rotate. The analysis is carried out for combined phase-locked translation and rotation with a single frequency. The results are presented for five set of the four dimensionless groups which characterize this flow. The resulting vortex formation modes and synchronization (lock-on) phenomena behind the cylinder (in the near-wake region) as well as the fluid forces acting on the cylinder are analyzed. In addition, a series of one-degree-of-freedom (1-DoF) forced vibration calculations are carried out to better understand what differences result from the addition of rotational oscillations to streamwise (in-line) or cross-stream (transverse) motion and to see which effects a transverse-only or in-line-only simulations miss. The numerical scheme is verified by applying it to the special cases of uniform flow past a stationary cylinder; a steadily rotating cylinder; a cylinder undergoing (1-DoF) forced (recti-linear or rotational) oscillations. Exceptionally good comparisons with previous experimental and numerical results are obtained. Furthermore, the simulations of the start-up flow for the case of combined (2-DoF) forced recti-linear and rotational cylinder oscillations at a moderate Reynolds number are consistent with the results of the analytical solution.

Masters thesis, Memorial University of Newfoundland.

abstract: Predispersal seed predation is a critical factor limiting population recruitment among a number of coniferous species in natural systems. Introduced species, a major threat to biodiversity, can cause high levels of predispersal seed predation. Balsam fir (Abies balsamea) regeneration and establishment has been an ongoing challenge for land managers on the island of Newfoundland due to paucity of adult trees producing female cones, and the fact that fir recruitment requires annual seed production as there is no seed bank. This study focused on the combined impact of a mammal and a suite of insects on pre-dispersal cone and seed mortality of balsam fir through investigation of ecological impacts of non-native red squirrels (Tamiasciurus hudsonicus) and a variety of predispersal cone/seed insects on this dominant tree species. Specifically, the impact of red squirrels and cone/seed insects were compared between balsam fir stands with different disturbance types and stem densities: Intact sites with no recent history of insect-infestation; and Insect Kill sites with recent history of insect infestation, around a range of stem densities (286-3100 trees/ha). The study was conducted within Terra Nova National Park and the surrounding forest management area in the southern Bonavista Bay region of the island of Newfoundland, Canada. -- The percentage of pollen cones lost to red squirrels (3.5 ± 7.3% to 84.6 ± 9.3%), with an average loss of 47.6 ± 3.9%, was significantly higher in study sites with low balsam fir stem densities (229 ± 76 trees/ha) than in sites with high balsam fir stem densities (826 ± 189 trees/ha). Pollen cone loss to red squirrels showed no significant variation between disturbance types and among sites with respect to tree height and diameter at breast height (DBH). The percentage of seed cone loss to red squirrels (33.0 ± 15.7% to 93.5 ± 3.3%), with an average loss of 58.9 ± 15.5%, was not significantly between high and low stem density sites, nor between disturbance types. The number of female cones taken by red squirrels also did not vary among trees with respect to DBH, height and cone crop size of trees. All cones sampled in the study showed some signs of insect damage with 21.4 ± 5.9% of sampled seeds in balsam fir stands showing signs of insect infestation. However, stem densities of study sites did not significantly influence seed loss to insects among trees. Furthermore, seed loss to insects did not appear to be influenced by age class, DBH, height, and average cone size of trees. However, the proportion of viable seeds prior to seed release was stem density-dependent, and increased with increasing balsam fir stem density. -- The results of the study suggest that red squirrel and insect populations were high, and hence were ubiquitous across the landscape. The combined effect of red squirrel and cone/seed insect predation resulted in over 2/3 reduction in potential seed production in all study sites combined. This may pose challenges to natural recruitment of balsam fir in the area, and a combination of Assisted Natural Regeneration, and seedling planting should be investigated as remedial options by managers of this area.

abstract: The search for which molecular players are involved in the transfer from short term memory to long term memory has led down several different avenues. The role of protein phosphatases in learning and memory has been one well-studied route of investigation. Specifically, protein phosphatase 2B (calcineurin, CN) has received a significant amount of attention due to its promotion of the dephosphorylation of CREB. Researchers have ascertained that over-expression of CN is associated with memory retention deficits and impaired memory consolidation in mice (Mansuy, Mayford, Jacob, Kandel & Bach, 1998; Foster, Sharrow, Masses, Norris, & Kumar, 2001). In contrast, CN inhibition enhances conditioned place preference (Gerdjikov & Beninger, 2005) and contextual learning (Ikegami & Inokuchi, 2000). -- The present study hypothesized that an infusion of FK506 (a CN inhibitor) bilaterally into the olfactory bulbs would prevent the dephosphorylation of CREB and, prolong the duration of a conditioned odor preference, which normally only lasts 24 h with a single training trial. On post natal day (PND) 6, rat pups received a 2 mg/kg subcutaneous injection of isoproterenol (ISO), a β-adrenoceptor agonist (the unconditioned stimulus, US), and after a 10 minute exposure to peppermint (the conditioned stimulus; CS) were infused with FK506 or vehicle into the olfactory bulbs. Subsequently, preference for peppermint was assessed 24 hrs, 48 hrs, 72 hrs, 96 hrs and 1 week after training. Immunohistochemistry for pCREB revealed that unilateral infusion of FK506 resulted in an amplification of phosphorylated CREB in the olfactory bulb 40 min after training relative to sham side infusions. Additionally, pups infused bilaterally with FK506 maintained a learned preference for peppermint 48, 72 and 96 hrs after training. These results support the hypothesis that prolonging CREB phosphorylation with CN inhibition can extend the duration of conditioned olfactory memory. -- CN inhibition also modified the conventional inverted U curve obtained when ISO is used to replace stroking, as the US. Under normal conditions, 2 mg/kg of systemic ISO is effective, while higher and lower doses are not able to produce learning. When pups were infused with FK506 to inhibit CN, learning occurred with the low dose of 1 mg/kg ISO, and with the higher dose 6 mg/kg. We assumed that high doses of ISO do not elicit olfactory memory due to excessive phosphatase activity, and that low doses do not provide sufficient cAMP activation. CN inhibition blocks phosphatase activity, thus allowing learning to occur at higher doses of ISO. For the low dose effect, we hypothesize that AC9, a positive regulator of cAMP inhibited by CN, is relieved from inhibition and cAMP production is increased to provide sufficient activity to phosphorylate CREB and produce learning following normally insufficient (1 mg/kg ISO) activation. Alternatively, normally subthreshold phosphorylation elicited by small elevations of cAMP via low dose ISO may be raised to suprathreshold levels by phosphatase inhibition. -- Calcineurin inhibitors thus have promise as memory enhancers since they facilitate memory initiation and memory duration from sub- to supra-optimal associative learning conditions.

A simple approach is presented based on specialization of an abstract algorithm representing an algorithm design approach. This provides not only reuse of the algorithm, but also reuse of its proof. Moreover, the simplicity and  applicability of the design techniques are not sacrificed. For each method, a problem is parameterized to create a specification, which is then transformed to a concrete algorithm following the proposed process.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: The research described in this thesis mainly dealt with methodology development, design and synthesis, as well as the study of the physical properties of new xanthones and xanthone-based molecules. An offshoot of this work was concerned with the development of a synthetic approach to novel cyclic oligophenylenes. The inverse electron demand Diels-Alder (IEDDA)-based methodology was employed in all of the projects. --  The first objective was to employ the IEDDA reaction in a new approach to xanthones. Specifically, nine new 2-substituted-4-methoxyxanthones 1.228a-i and eight new 2-substituted-3,4-dimethoxyxanthones 1.229a-h were synthesized using IEDDA-driven domino reactions between chromone-fused dienes 1.15 and the corresponding electron-rich dienophiles 1.225 and 1.226, respectively. This work is described in Chapter 2. This methodology was also employed for the synthesis of arylxanthones in Chapter 3. A series of 2-aryl-4-methoxyxanthones 3.9a-c and 2-substituted-4-phenylxanthone, such as 3.18, was obtained from the reactions of the corresponding dienes 3.8a-c or 1.15b with dienophile 1.227. However, the desired 2,4-diarylxanthones 3.10 could not be synthesized by this method. -- The second objective was to synthesize two different types of hetero[5]acenes from appropriate xanthone frameworks, i.e. 3,4-dimethoxyxanthones and 4-methoxyxanthones, which were successfully obtained by the established IEDDA methodology. For example, Chapter 4 describes the synthesis of xanthonoid hetero[5]acenes 4.22 and 4.12-4.14 from the key intermediate 3,4-dimethoxyxanthone 4.23 via a selective demethylation, followed by an intramolecular nucleophilic aromatic substitution. Among these newly-synthesized compounds, hetero[5]acene-based crown ether 4.14 was designed for future complexation studies with ions toward chemosensor applications. The attempted synthesis of hetero[n]acenes (n = 5, 9) using double IEDDA reactions suffered from difficulties in the isolation of bis(diene) intermediate 4.26. At best, trace amounts only of hetero[5]acene 4.25b (mass spectroscopic analysis) were obtained. -- In Chapter 5, another class of hetero[5]acenes, referred to as iwdonor-acceptor xanthone-carbazole hybrid systems, was constructed from key intermediate 2-o-nitrophenyl-4-methoxyxanthones 5.31a-f and 5.38, via microwave-assisted Cadogan reactions, followed by zV-alkylation. A series of xanthone-carbazoles with or without substituents (OMe, Br) was synthesized, in which the “angular” isomers are the major product and the “linear” isomers are the minor ones in all cases. Suzuki couplings were effective in the synthesis of aryl-substituted xanthone-carbazole compounds. Physical studies on newly-synthesized xanthone-carbazoles showed some interesting features. For instance, the angular isomers show green fluorescence and quasi-reversible redox behaviour, while the linear ones show blue fluorescence in most cases and irreversible redox behaviour. Most of the xanthone-carbazoles exhibit moderate fluorescence quantum yields, narrow HOMO-LUMO energy gaps, low HOMO energies, and some of them have close interplanar distances in solid-state packing (X-ray analysis), which make them very promising candidates in OLED or OFET applications. -- Finally, in Chapter 6, the synthesis of a cyclic oligophenylene was attempted using a six-fold IEDDA reaction. Although this project was unsuccessful, investigations aimed at the improvement of the reaction conditions as well as the design of a more reactive bis(diene) should be informative to future work.

abstract: This thesis is a theoretical approach to study the magnetic phase transitions and exchange interactions in the spiral magnet TbMnO₃ by using group theory. First, we study the magnetic and ferroelectric transitions by considering the symmetry breaking associated with each transition. Second, we write the exchange interactions for the Mn magnetic ions in terms of the magnetic order parameters which are associated with various irreducible representations of the magnetic space group. Third, considering the exchange interactions and single ion anisotropy we examine the interactions on the whole lattice. -- The most general form of the exchange interactions for Mn atoms in TbMnO₃ is formulated, including nearest neighbor and next-nearest neighbor interactions. Our phenomenological model also contains antisymmetric terms which lead to a mixing of spin-wave polarizations. It is found that for each exchange path there are six independent exchange terms, leading to a rather complicated Hamiltonian. -- Finally, equations of motions for spin waves are derived. Particular attention is given to the high-temperature phase (phase I) with the sinusoidal antiferromagnetic arrangement of spins and the incommensurate wave vector Q. The symmetric case and the degeneracy in the spin-wave spectrum in this phase are also discussed. More complex magnetic interactions lead to the spiral phase lying in the bc plane. This is the low-temperature phase (phase II) which needs further theoretical analyses.

Masters thesis, Memorial University of Newfoundland.

abstract: The tectonic framework and depositional settings of the Orphan Basin are studied using ~25,000 km of 2-D seismic reflection profiles and stratigraphic data from nine key exploration wells. The evolution of the region is recorded in five seismic distinct stratigraphic units (Z, A, B, C, X), each separated from one another by widespread regional markers U1-U4, representing prominent unconformities. Exploration well data showed that Units Z, A, B, C and X are correlated with the Pre-Cambrian/Paleozoic basement, ?Triassic/Jurassic, Early Cretaceous, Late Cretaceous and Tertiary successions, respectively. Similarly, the well data showed that U1, U2, U3 and U4 markers are correlated with the Top Paleozoic, Top Jurassic, Mid-Cretaceous and Base Tertiary Unconformities, respectively. The well data further showed that the seismic Units A, B+C, and X are broadly correlated with three regional tectonic episodes, where each episode includes a period of extension, followed by a period of protracted uplift associated with sectoral break-up, and a period of sustained thermally-driven subsidence. -- On the basis of stratigraphic and structural architecture of the successions imaged between the Top Paleozoic Unconformity and the Base Tertiary Unconformity, the study area is divided into five tectonic provinces: the Western and Southwestern Basin Margin, the Eastern Basin Margin, the White Sail Fault Zone, the West Basin and Ridge Province, and the East Basin. The Bonavista and White Sail Fault Zones were developed during the ?Jurassic (may be as early as Triassic if evaporates are present in the Orphan Basin), as prominent basin-bounding faults.  Several large faults paralleling the White Sail Fault Zone also developed during this time. The extensional tectonic activity continued in the study area throughout the Cretaceous, but slowly culminated in the late Cretaceous / Early Tertiary as indicated by the absence of growth strata within the Tertiary succession associated with the faults, and tip points of these faults being situated in the Early Tertiary successions. -- The seismic data documents that faults in the northern and northeastern segment of the Orphan Basin display greater growth, rotation and tilting of the mid-Late Cretaceous successions than those observed in the western and southern segment of the basin. These observations together with the large fan-shaped fault splays of the White Sail Fault Zone collectively suggest that the Flemish Cap probably experienced a progressive clockwise rotation of 25°-35° during the Late Jurassic - Late Cretaceous. This rotation and extrusion of the Flemish Cap is largely accommodated by the Cumberland Belt Fault Zone in the south and the Charlie Gibbs Transfer Zone in the north.

abstract: Most trauma research has addressed only the painful, often devastating effects of traumatic experiences on individuals, and thus has left unexplored the opportunity to move beyond survival or recovery to positive outcomes. While a small but growing body of research has focused on positive as well as negative changes after trauma, most of these studies use quantitative methods to understand this change and have focused almost exclusively on elements associated with outcomes rather than on the process an individual may progress through toward these outcomes. This investigation is unique in its study of the process into living well after rape, as experienced and understood by a group of adult women. It is meant to be research for, rather than on, women - in which the research process empowers by focusing on women's agency, providing new accounts of women's experience, and attending to both personal and social potential and transformation. Through multiple individual participant-guided interviews, ten women shared their stories. While interviewing women, the inadequacies of dominant scripts to assist in understanding rape itself and to support positive change after rape became evident. Prevailing narratives available to women are influenced deeply by medical, legal, and social framings of women's lives, resulting in, at best, a focus on the amelioration of negative effects. These influences have challenged and obscured women's post-rape experiences of progressing toward living well. Following Kathy Charmaz's constructivist approach to grounded theory, I explore the process participants navigated and strategies they used to transcend limiting discourses and grow toward living well. The interpretations reflect a long, complex, and multi-dimensional process that involved three phases. While progress tended to be slow, breakthroughs of more significant progress occurred that assisted women in their transition into subsequent phases, often with the assistance of allies. Further, participants described their progress from one phase of the process to the next as secure and irreversible due to fundamental developments in themselves and their understanding of rape. Strategies developed by women to deconstruct and reconstruct rape scripts in order to progress toward living well are discussed, and implications for informal and professional allies are considered.

abstract: The dynamic nature of distributed generation (e.g. from wind) makes to design a control system for wind turbines that utilize wind energy. The design of a wind turbine control system becomes more difficult when the system is operated in grid-connected mode. The major issues include connection standard, control system complexity, cost and required instrumentation. A low cost control system and its associated instrumentation development is very important for commercial success of a small grid connected inverter based wind turbine. The proposed grid connected inverter based remote control system is a good candidate for distributed generation system such as a small wind turbine. -- The main purpose of this research is to present a novel remote power control for a small single phase grid connected inverter using a DC-DC converter and an ADR101 serial data acquisition card. Before grid connection characteristics of the inverter are programmed for a desired input DC voltage for generating the output electrical power. Input dc voltage of the inverter is adjusted by controlling the DC-DC converter. A PC is employed to receive the required output power signal from a dispatch center via the Internet. The PC determines the power being fed by the inverter to the grid and uses an ADR101 to control the dc-dc converter to adjust the power flow to the grid. -- The performance of the developed control system investigated both in simulation and experiment. DC power supply is used at generation side and inverter output at grid side is adjusted based on an existing data file in PC. A PI controller is designed which makes sure that power flow is always the same as required by the electrical power dispatch center. -- The applicability of the proposed remote control system based on a 250 watts grid connected inverter is demonstrated through a number of lab tests. The results show the designed control system is capable of remotely controlling the system power of the grid tie inverter.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: There is no evolutionary, ecological or behavioural explanation for the partitioning of parental roles between the sexes in the Alcini, which includes murres (Uria), the razorbill, (Alca torda), great auk (Penguinus impennis) and dovekie (Alle alle); and why the male is the selected sex to accompany the chick to sea. I investigated parental roles and diving behaviour of two sympatric alcids, thick-billed murres, Uria lomvia, and razorbills, at the Gannet Islands, Labrador to determine whether sex-specific differences in energy expenditure at the time of departure explain male-only care at sea. Externally attached time-depth recorders (TDRs) negatively affected parental behaviour in male and female thick-billed murres. Partners of TDR-equipped birds compensated for the reduced parental effort in brooding and chick provisioning of their mates, with no differential responses between sexes. There was a temporal segregation of water depths, dive profiles, and food resources between the sexes in both species; these differences being stronger in thick-billed murres than in razorbills. Most murre females' self-feeding diving coincided with the vertical migration of crustaceans to surface waters; while male's self-feeding foraging occurred when prey were in deeper sections of the water column. Chick-provisioning diving was deeper than self-feeding irrespective of the sex or the time of day, suggesting equal parental effort allocation of the sexes underwater. Nevertheless, males had longer foraging trips than females probably due to the time spend flying to farther locations than females. Higher self-feeding rates and closer feeding locations may explain female's higher delivery rates at the breeding site. The longer time males spent brooding the chicks may serve to ensure parent-offspring vocal recognition at departure. Larger bill dimensions and higher levels of aggressive behaviour may confer males a better ability to protect the chick. In conclusion, differences in energy expenditure between the sexes did not seem to explain the male's parental role at sea. Instead, I proposed that the patterns of parental roles found between sexes was the result of a chain of events favouring male involvement in chick brooding and care at sea. A higher level of aggressiveness of the parent that escorts the chick to sea may have been selected for to ensure offspring survival, and as a result, parental roles developed at the breeding site to ensure male-only care at sea.

abstract: A series of three experiments were completed to further study the relation of kindled site and baseline anxiety levels to plus maze behavior in Wistar rats. Results indicated that the behavioral outcomes found one week post kindling for animals kindled in central amygdala, the medial amygdala, the basolateral amygdala, and the nucleus basalis differed depending on the location of the kindled site. In addition, the results showed that the nature of behavioral outcomes for animals kindled in the right medial amygdala and basolateral amygdala were dependent on pre-kindling baseline anxiety levels, measured using a novel retest procedure. Taken together, the above results indicate that both location of kindled site and the pre-kindling baseline anxiety levels of rats play a role in determining post-kindling behavioral outcomes in the elevated plus maze. These results may explain inconsistencies in previous studies related to the behavioral effects of kindling.

Masters thesis, Memorial University of Newfoundland.

abstract: I examine the patterns of variation in the larval fish community from coastal Newfoundland using data from 68 surveys conducted during the summer months between 1982 and 2002. I review the literature concerning changes in the adult fish community that have taken place, and then review the hypotheses about their possible causes. The principle debate surrounding the collapse of the Newfoundland groundfish deals with the relative roles of fishing pressure versus the potential influence of seawater temperature during the years following peak fishing pressure in the 1960's. I address whether differences in gear type (Bongo vs. Ring nets) might affect my ability to detect changes in the larval fish community as a result of selection loss or avoidance. Based on the results of statistical comparisons and on calculated catch ratios of < 1.61 concluded that no consistent bias was present as a result of gear type and that the abundance data in this study are sufficiently comparable for use in larger temporal studies. I then contrast temporal changes in the larval community of three bays. Based on Multidimensional Scaling plots, Group Average Cluster Analysis and species abundance plots, I concluded that temperature (seasonal structure) plays a role in determining community composition of the larval fish studied, producing distinct larval assemblages at specific times of the year. I also concluded that below average water temperatures during the early 1990's affected the community composition of the larva; as cold-water species were unusually present during summer months. Additionally Analysis of Similarity showed that larval species abundance significantly decreased post 1992 and some non-commercial species showed smaller declines in abundance than those commercially targeted. Finally, I examine the scale at which these changes have occurred, to determine whether large-scale temporal changes occur in species diversity or dominance, and whether changes correlate within and among the bays surrounding Newfoundland's Avalon Peninsula. Larval fish abundance displayed significant changes during the same time periods in all the bays examined in this study. However, further investigation is needed before conclusions can be made regarding how species composition differs in the bays surrounding the Avalon Peninsula.

abstract: Work-related musculoskeletal disorders (WMSDs) are common in workplaces where repetitive work is performed. Although these conditions have been recognized for a long time and studied extensively there are considerable gaps in the research on how workers who have developed a WMSD are able to remain at work and what strategies they use to make this possible. The purpose of this study was to develop an understanding of the psychosocial process or processes and the strategies used by employed injured workers in dealing with WMSDs. Specifically, the research question was, 'How are workers who have developed a WMSD able to remain at work and what strategies do they use to make this possible?' Grounded theory was used as the research methodology. Participants included twenty-five (16 male and 9 female) workers diagnosed with WMSDs who were currently employed in various workplaces in Newfoundland and Labrador. Constant negotiating was found to be the core category central to the process of remaining in the workplace that enabled workers to respond to social, health, and occupational environments. The process included five main phases: Becoming Concerned, Getting Medical Help, Dealing with the Workplace, Making Adjustments to Lifestyle, and Taking Charge, as well as various sub-phases. Findings from this study suggest important implications related to nursing practice, education, and research. Implications for employers are also included.

abstract: In this thesis, the performance of GFRP bars used as the main reinforcement for high strength concrete two-way slabs is investigated. A total of six interior slab-column connections, were cast and tested to failure at the structural laboratory of MUN. The dimensions of the simply supported tested slabs were 1900 X 1900 mm square and the thicknesses were 150 and 200 mm. -- The reinforcement ratio and the clear concrete covers were the main variables in this investigation. A transverse central load was applied to the slabs through a central column stub. The structural behavior of the test specimens was investigated in terms of load-deflection, crack pattern and spacing, deflection profile, concrete and GFRP strains, failure mode and ultimate carrying capacity. Six slabs made of high strength concrete were constructed and reinforced with 16 mm GFRP bars. One slab was cast as a reference specimen using high strength concrete reinforced with traditional steel rebars.  -- The test results revealed that the slabs reinforced with GFRP bars exhibit higher deflection and wider crack width compared to similar slabs with conventional steel rebars. The load carrying capacity of the tested slabs was lower than the reference slab reinforced with steel rebars. However, slab performance can be improved by increasing slab depth. -- The use of high strength concrete improved the slab ultimate load capacity and reduced the total deflection of the slab. High strength two-way slabs reinforced with GFRP show more ductility than the slabs reinforced with tradition steel; however, in terms of energy absorption, the slab reinforced with steel rebars shows higher values than the GFRP slabs. -- The existing code limitations for serviceability limit state for crack width and spacing expressions were compared with the experimental results to verify their applicability in predicting crack width and spacing. -- An existing numerical model and related expressions to calculate the crack width and spacing were adopted and modified to account for the low modulus of elasticity and weak bond properties associated with the use of GFRP rebars. The modified model and expression results were compared to the experimental recorded data. The modified crack model and expressions provide excellent agreement with the experimental results. -- Finally, a finite element ABAQUS model was modified and adapted to predict the structural behaviour of high strength two-way slabs reinforced with GFRP. The finite elements model provides useful agreement with the experimental results in terms of ultimate load and maximum deformations.
