abstract: The objective of this project has been to develop a filtering technique which will enable the recovery of a wide-sense stationary, stochastic signal process, from a two-dimensional image. It is assumed that the image is contaminated by a stationary broad-band noise process, having a spatial extent of correlation, represented by c, which is much less than the spatial extent of correlation within the signal process. Under such conditions, it is possible to derive a three- channel Wiener filter which operates on the past values of a coherent data sequence, in order to predict a future value. By setting the prediction gap, α, to be greater than c, the predicted output sequence will be a noise-suppressed version of the input. The three-channel filler accepts as input, three rows of the image, and then produces a single output which is a filtered estimate of the signal process occurring within the middle row of the input triplet. Each row within this triplet is separated by a distance, β, which is held constant for all row triplets during the filtering operation. After operating on all possible row triplets, the same procedure is repeated for column triplets. It has been demonstrated that the three-channel filter has a greater capacity for noise- suppression, when compared to single-channel versions. By choosing the value of β to be greater than c, this noise suppression capability is optimized. -- This research has verified that the three-channel Wiener filter is effective in suppressing correlated speckle noise, within ocean wave scenes imaged by airborne Synthetic Aperture Radar, However, due to the exponentially-damped nature of the correlation functions which characterize the bandpass signal process within such images, it has also been shown that the filtered estimates are directly dependent upon the values chosen for α and β. In fact, if two different filtering operators are derived, each with a different combination of values for α and β, then they will each produce a different filtered estimate after operating on the same input image. Consequently, the accuracy of the filtering operation will vary according to the choices which are made regarding these parameters. The most accurate filtered estimates of the bandpass process are achieved with small parametric values. Since α must assume a value which is greater than c, and since it is preferable that β should also, it logically follows that the extent of noise correlation within any image will predetermine the degree of accuracy which can be achieved by use of this technique. -- The three-channel Wiener filtering technique will have practical noise-suppression applications, relating to the extraction of more accurate wave feature information from speckle- contaminated SAR images of ocean scenes. Furthermore, since the use of large α and β restricts recovery to only a portion of a bandpass signal, this technique may be suitable for the isolation and enhancement of low-frequency, low-power wave components, which may be otherwise obscured by higher-frequency wind-generated waves.

title: Quantifications of random variables

type: Thesis NonPeerReviewed

format: application/pdf application/pdf

abstract: Order restricted inference is an important field in statistical science. The utilization of ordering informations can increase the efficiency of statistical inference procedures in several senses, see Ayer, Brunk, Ewing. Reid. and Silverman (1955), Robertson and Wright (1974), Barlow and Ubhaya (1971), Lee (1981) and Kelly (1989). -- In this thesis we review some basic theories about the least squares regressions, particularly the isotonic regressions. We give a simplified proof of an iterative procedure proposed by Dykstra (1983) for least squares problems. -- We investigate the properties of the orderings of real-valued functions from several aspects. Some definitions are extended and their properties are generalized. We also show that the concept of closed convex cones and their duals is important in estimating procedures as well as in testing procedures. We demonstrate that some seemingly different problems have actually the same likelihood ratio test statistics and critical regions. -- We observe that the orders of real-valued functions and the orders of random variables are closely related and statistical inference regarding these two orders behave similarly. A class of bivariate quantifications are defined based on these two orders. This bivariate notion has direct interpretation and appealing properties. More important, it characterizes a degree of positive dependence among random variables and therefore makes it possible to study the positive dependence of random variables by using the theories of the orders of real-valued functions and the orders of random variables. -- We consider several estimation problems under order restrictions. We propose an algorithm that finds the nonparametric maximum likelihood estimates of a stochastically bounded survival function in finite steps, usually two or three steps. Simulation study shows that in general, utilizing the prior knowledge of a lower bound and an upper bound may reduce the point-wise MSE's and the amount of reduction in MSE's could be substantial for small and moderate sample sizes for a pair of sharp bounds. We obtain the estimates of a multinomial parameter under various order constraints for a general multinomial estimation procedure defined by Cressie and Read (1984). -- We also consider the problem of simulating tail probabilities with a known stochastic bound. The proposed procedure may increase the efficiency of simulation significantly.

abstract: This thesis presents the development and implementation of a Finite Volume Method (FVM) to simulate the sloshing behaviour of incompressible, constant density liquids in a two- dimensional, rigid rectangular tank. The phenomenon of sloshing is of importance to engineers involved in the design of all types of vehicles which transport confined liquids. This paper reports on the research conducted in the context of the transport of liquids on the ocean surface. The method presented has two immediate applications in this context: the transport of petroleum products, and roll stabilization systems for ocean-going vessels. -- The FVM is used to discretize the governing momentum and mass conservation equations using primitive variables in a fully Eulerian approach. The method is formulated by integrating the governing equations over appropriate control volumes, and assembling systems of linear equations. A fixed rectangular grid with variable spacing is utilized, and momentum control volumes (CVs) are staggered relative to the continuity CVs. The inertial accelerations caused by a specified tank motion are applied to the fluid by the inclusion of additional source terms in the momentum equations. The method can accommodate the simultaneous translation and rotation of the tank relative to an absolute reference frame, and rotation of the tank about a frame attached to it. -- The free surface boundary is handled using the Volume of Fluid (VOF) method, which permits arbitrary movement of the surface, including the possibility of overlapping and smaller regions breaking away. The VOF method is based on the assignment of a variable Ffor each continuity CV, where F represents the average fraction of the cell volume which is occupied by fluid. The VOF method, therefore, defines the shape of the fluid-occupied calculation domain, and the free surface. -- Results were obtained in the form of the free surface configuration, and velocity and pressure distributions throughout the fluid domain. Results are presented for various prescribed tank motions, chosen to verify the method's stability, reliability, and conformance to behaviour predicted by other established means. Prescribed tank motions were; (i) rotation to a constant angle of inclination; (ii) excitation with the predicted natural period; (iii) excitation near the natural period (producing a surface wave with a beating behaviour ); (iv) impulsive translation; (v) continuous rotation; and (vi) arbitrary simultaneous rotation and translation. All input tank motions are of a sinusoidal form. The method generated results in good agreement with expected physical behaviour. In particular, the wave period characteristics has been verified, and the ability of the method to accommodate a combined rotational and translational tank motion (representing ship roll and sway) lias been proven. -- To fully develop and define the capabilities of the proposed method, it is necessary to conduct further testing of the method to verify the surface heights calculated, and to optimize the use of various calculation parameters. In addition, testing with general tank motion (i.e. roll, sway, and heave), and with motions extreme in nature, is recommended. It is also recommended that a version of this method be developed to model a three-dimensional rectangular tank, thus ensuring its applicability to the widest possible range of practical design problems.

abstract: Tropomyosin is a polymeric protein found in the muscle thin filament together with actin and troponin. The end regions, which encompass the first and last 10-11 amino acids, are vital to its function. We have analyzed the role of the amino-terminal region by selective removal of the first six amino acids. A method describing the hydrolysis of the sixth peptide bond of tropomyosin by bacterial outer membrane protease T (Omp T) is described. -- Compared to the native counterparts, shortened forms of rabbit skeletal and Atlantic salmon fast skeletal tropomyosins (residues 7 - 284), as well as the unacetylated (residues 1 - 284) version of the latter, all display reduced affinity for both troponin and the amino-terminal fragment of rabbit skeletal troponin-T (N-Tn-T, residues 1 - 158), as judged by affinity chromatography. Thus, loss of the hexapeptide, together with the blocking group, weakens the binding of tropomyosin and troponin-T. Omp T-digested tropomyosin binds weakly to F-actin in the micromolar concentration range, but this interaction is restored by troponin. At moderate ionic strength (50mM KC1), the apparent Kds are: 0.26 uM (+EGTA) and 1.6 uM (+Ca2+). The inductive property of troponin is attributable, in part, to troponin-I. But whereas the amino-terminal fragment of troponin- T (residues 1-158) enhances troponin-I-induced F-actin binding of two other tropomyosin products which have weak affinity for F-actin, specifically, recombinant unacetylated tropomyosin (residues 1 - 284) and carboxypeptidase-digested tropomyosin (residues 1 - 273, Heeley, D. H. et al (1987) J. Biol. Chem. 262,9971-9978), it is ineffective in the case of the Omp T-digested protein. These data are evidence for a troponin-T binding site within the amino-terminal region of tropomyosin. -- In assays that contain myosin, thin filaments composed of Omp T-digested tropomyosin are less cooperative than native thin filaments, consistent with the disruption of physical continuity within the filament. At the same time, however, the truncated system (+Ca2+, ionic strength, 22mM) activates myosin to a greater extent than native tropomyosin, and has stronger affinity for myosin-Sl-ADP (+EGTA; ionic strength, 70mM), the reverse of what has been observed with the carboxy-terminally-shortened protein. These results suggest that the amino-terminal region of tropomyosin is an inhibitory thin filament element, which stabilizes the off-state of the thin filament via an interaction with the tail section of troponin-T, and that the two ends at the overlap complex have opposing regulatory roles. -- Finally, the conformational stability of tropomyosins from Atlantic salmon was characterized under a variety of conditions (salt, pH and osmolyte). The most variable sections of sequence encompass residues 9-49, 73-87 and 172-216. In two of these hotspots there is a pair of closely-spaced glycines, namely at residues 24 and 27 in fast skeletal tropomyosin and residues 83 and 87 in cardiac tropomyosin. Further, the isoform from fast muscle does not have a d position alanine between residues 172-216 due to the isomorphism Alal79Thr and thus lacks the fifth alanine cluster. These substitutions have reduced the conformational stability of the fish protein compared to the mammalian counterpart and provide insight into the adaptation of tropomyosin to cold temperature.

abstract: This two part report describes a counselling internship and research project carried out at the College of the North Atlantic, Corner Brook campus, in the spring semester of 1998. -- Prior to the commencement of the internship, the intern in collaboration with her supervisor and primary field supervisor, set realistic, obtainable goals. Part One of the report describes activities undertaken to reach these goals. These goals were aimed at improving counselling skills and gaining experience. -- One goal was to complete a research study related to the placement. The research consisted of a survey of students' perceptions of, use of, and satisfaction with counselling services offered at the College of the North Atlantic. Interviews were also conducted with student services personnel to collect data related to role descriptions and program planning to meet student needs. The study found that 83% of students surveyed were aware that counselling services were available, 29% had used the services and the services with the highest satisfactory ratings were Academic Performance and Study Skills and Program/Resource Information. Structured interviews with counsellors and other members of the student services team produced agreement that all services of the Student Services Department should be promoted to students and faculty. The research is discussed in detail in Part Two of this report.

abstract: The p-version finite element method offers a distinct advantage of savings in computational time and effort in comparison with the conventional, h-version finite element method. The h-version uses low order elements and convergence studies are done by successive refinements of the mesh that imply analyzing the problem afresh. In contrast, the p-version uses a fixed discretization of the domain and higher order elements are successively employed during convergence studies. The computational advantage results from the use of hierarchical shape functions, coarse meshes and faster rates of convergence with decreased number of degrees of freedom. Consequently, the use of hierarchical finite elements can be especially advantageous for stress concentration and stress singularity problems that require very refined meshes in the h-version. -- The accuracy of hierarchical finite elements is demonstrated with the use of coarse meshes for beam and T-plate weld joint problems. A 2D enriched hierarchical finite element is developed for stress intensity factor evaluation that embodies the inverse square root stress singularity by including in its formulation the stress intensity factors as additional degrees of freedom. Stress intensity factors for cracked specimens are numerically evaluated quite accurately using very coarse meshes involving fewer degrees of freedom in comparison with conventional analyses. This concept is then extended to 3D crack problems and favourable results are obtained.

abstract: The purpose of this study was to explore the program evaluation methods employed at an autonomous distance education institution, focusing in particular on the derivation and application of standards within the evaluation process.  This study also attempted to examine the relationship between the data gathered and theory and models in the evaluation literature.  The study was initiated to provide baseline data on the application and derivation of standards as this subject is not addressed extensively in the literature. -- Using an interpretive case study approach this study was implemented in the summer of 1995, and employed semi- structured to unstructured interviews, questionnaires and document analysis to elicit information. All interviews permitted open responses, and were tape-recorded with the permission of respondents. -- The data were initially analyzed using Kripendorffs (1980) semantic content analysis resulting in a narrative report.  This was followed by the development of categories and themes as suggested by Merriam (1988) in order to interpret and theorize about the data with reference to the literature. -- Results of the study indicated that no one approach to the setting and use of standards and criteria is employed. Input from stakeholders, the development of performance indicators by departments, university policy, use of baseline data and comparative data from the literature and other institutions all contribute to the derivation of standards.

Masters thesis, Memorial University of Newfoundland.

abstract: This study investigated the interrelationships among parental expectations, children's perceptions of parental expectations, children's attitudes toward reading, children's self-concepts as readers and children's reading comprehension. The effects of gender on these variables were also examined. Relationships among these variables provided support for parents and teachers to create positive, realistic expectations, in order to promote maximum reading comprehension. -- Scores obtained from forty children and their parents and or guardians, on instruments measuring the above variables were correlated. As well, analysis of variance tests were performed to determine gender effects for parental expectations, on children's perceptions of parental expectations,  attitudes toward reading,  self-concepts as readers and reading comprehension. -- An analysis of variance was also used to test for gender effects on children's perceptions  of  parental  expectations,  attitudes  toward reading, self-concepts as readers and reading comprehension. Significant relationships were found between parental expectations and children's reading comprehension, children's perceptions of parental expectations and their self-concepts as readers as well as between children's self-concepts as readers and their reading comprehension. There were no significant relationships between a) mother's or father's expectations for children's reading and children's reading comprehension, b) parent's, mother's or father's expectations for children's reading and children's attitudes toward reading, c) parent's, mother's or father's expectations for children's reading and children's self-concepts as readers, or d) children's attitudes toward reading and children's reading comprehension. However, significant relationships existed between specific variables within the overall measures. Gender was found to have a significant effect only on parental expectations for children's reading comprehension and children's self-concepts as readers. Parents held higher expectations for females' reading comprehension than for males'. Fathers' expectations affected females' self-concepts as readers more than did mother's expectations. -- Children perceived what their parents expected for them in reading. Their perceptions of parental expectations were related to their self-concepts as readers. Children's self- concepts as readers were related to their reading comprehension. Consequently, this study supports the need for parents to create positive, realistic expectations and to clearly communicate them to children.

Masters thesis, Memorial University of Newfoundland.

abstract: This study investigated the perceived role of mental skills training in injury rehabilitation among Atlantic University Sport (AUS) athletes. The Trew Mental Skills Training and Injury Rehabilitation Questionnaire was developed by the investigator. The questionnaire, letters of introduction and self-addressed stamped envelopes were distributed to the coaches of AUS teams who were actively competitive at the time of this study. A total of two hundred and ninety questionnaires were completed and returned. The findings indicated that of the 78.3% of athletes who reported sustaining an injury, only 21% of these athletes used mental skills training as part of their injury rehabilitation programs. AUS athletes (62%) also indicated that they would be willing to use mental skills training in future injury rehabilitation programs. This study concluded that although many AUS athletes use mental skills training to enhance performance, they are not being provided with many opportunities to implement mental skills training into injury rehabilitation programs.

abstract: This thesis describes investigations into the applicability of inert atmosphere: matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) technique for rapid screening of reactions. Complexation reactions of lanthanide amide reagents Ln{N(SiMe₃ )2}₃  (where Ln = Sm, Gd, Ho, Yb, Y or La) with amine-bis(phenol) ligands ([O₂N₂t -Bu,Me H2, [O₂ N₂t -Bu H₂ and [O₂ NN't-Am ]H₂ ) were probed using anthracene as the matrix. This technique rapidly confirmed ligand coordination by showing excellent agreement between the experimental and theoretical isotope patterns. Spectra of isolated lanthanide amine-bis(phenolate) amido complexes are similar to those seen from small scale parallel reactions of metal amides and protonated ligands. Although in all cases molecular ion peaks were not observed, peaks for lanthanide arene complexes, [M + arene] + , formed in situ , were seen. The absence of these molecular ion peaks was due to difficulties in ionizing Ln³⁺ complexes by charge-transfer, and the low coordination number of the lanthanide ions led to laser-assisted arene complex formation. The mechanism of ionization in this study is proposed to involve adduct formation. -- The screening of the hydroamination-cyclization reaction of 5-phenyl-4-pentyne-1-amine potentially catalyzed by various lanthanide amine bis(phenolate) complexes was also studied. Characterization of the reaction mixtures from in situ hydroamination reactions showed changes in mass spectral patterns from the starting materials. Also, significant differences in the spectra of the mixtures containing lanthanide [O₂N₂] and [O₂N₂] complexes were observed. The aminoalkyne substrate is proposed to coordinate to the metal center of the lanthanide bearing [O₂N₂] complexes indicating potential precatalysts for hydroamination of aminoalkynes. These results demonstrate the utility of MALDI-TOF MS as a potential technique for rapid screening of reactions of paramagnetic and extremely moisture-sensitive metal complexes.

abstract: The Salvation Army has enjoyed more success on the island of Newfoundland than in any other province in Canada. Though Newfoundland has long been a stronghold for The Salvation Army very few academic studies exist that deal with the Army's arrival and growth. When the first Salvationists came to Newfoundland at the end of the nineteenth century, the island was in the grips of a depression and the fishers were struggling to survive. These elements, in combination with the island's geography and system of trade, proved beneficial to the Army. The Salvationist's methods of recruitment and preaching provided Newfoundlanders with entertainment and served to entice a number of people to join The Salvation Army. The Army was never a serious threat to the three main denominations: the Church of England, the Methodist Church, and the Catholic Church, and its popularity was limited in both size and location, but the Salvationists in Newfoundland have proven to be the Canadian Salvation Army's strongest and most abundant supporters. -- The present-day Salvationist owes a debt to the men and women who took a chance on a strange and seemingly disrespectable religion. The early Salvationists were drawn into the sectarian hostility which existed in nineteenth-century Newfoundland soon after they arrived. Yet. these people continued their work and the Army became a permanent part of the island's religious community.

abstract: This thesis examines the history of fisheries development in Newfoundland from World War II to the mid-1960s. In this period, the Newfoundland fishery underwent a dramatic shift, as the older, saltfish industry based on the household economy declined and a new, industrial, frozen fish industry arose in its place. The central question this thesis poses is what was the role of the state in fisheries development and what factors affected the direction of fisheries development? What was the relationship between capital and the state in the development process? Why was the industrial solution, the capital expansion in the frozen fish industry a dominant agenda in fisheries planning. Were there other alternative visions of development that were lost? How did the growth of the foreign fishing fleets in the late 1950s and early 1960s have an affect on the needs of the fishery and fishing people, as well as the state's response to these problems. -- Essentially, this thesis reveals the interconnected web of factors - the multi- layered state, capital, market structures, technology, international relations, demands of fishing industry organizations and fishers' groups and competing visions of the fishery in Newfoundland held by people at all levels of the state and society that influenced the course of development. All factors, however, were not equal, and this thesis employs the Gramscian concept of hegemony to explain how a particular vision of development - the expansion of the industrial, frozen fish sector - came to dominate fisheries policies in this period. Indeed, the hegemonic model of fisheries development, with its connections to the larger western, industrial capitalist culture, first appeared in Newfoundland during the Commission of Government era and has continued to command policy agendas ever since. Providing the cement for the industrial model of development was the relationship that arose between the state and a segment of the capitalist class - a small group of frozen fish companies in Newfoundland. This alliance between capital and the state has been a characteristic feature of post-war fisheries development in Newfoundland. As well, having a profound effect on the course of fisheries development was the intensification of foreign fishing off the Newfoundland coast that began in the mid- 1950s. Not only did this event have an impact on the resource itself, but it also changed the needs and demands of the fishing industry and fishing people. Taken together, the rise of the hegemonic model of fisheries development and the escalation of the international fishery would have profound repercussions for the fishery of the future.

abstract: This study investigated factors associated with changes in the occupational aspiration status (CA) of early school leavers in Newfoundland. The status of the occupational aspiration was represented by the presence or absence of an occupational goal in 1988 and 1992. Four CA groups were possible: no aspirations (NA), lost aspirations (LA), gained aspirations (GA) and maintained aspirations (MA). -- While the literature on occupational aspirations and their correlates is large, only a few studies of the process of change in aspirations have been reported. A review of the literature suggested that there would be a relationship between CA and the following variables: gender, region of residence, employment experience, education experience and perception of goal-blockages. Statistical procedures consisted of three-way and four-way crosstabulations, three- way ANOVAs and loglinear analyses, according to the nature of the variables. -- The four CA groups differed significantly in terms of the variables analyzed. Respondents in the NA group tended to be female, reside in rural regions, experience the lowest amounts of employment and education experience and perceive several goal-blockages. Similar numbers of males and females were in the LA group, with the majority living in rural areas. Employment experience was moderate, participation in education was low and they tended to perceive a lack of work and difficulty in finding work they liked as goal-blockages. There was a concentration of females in the GA group, residing in both urban and rural areas. Work experience was moderate and education experience was low. This group perceived their lack of job search skills and their education as goal- blockages. Those in the MA group tended to be males residing in urban areas. They experienced the greatest amounts of work experience and were most likely to have attended school. In general, these early school leavers perceived goal-blockages less frequently than any other group. -- Programming recommendations addressed the following issues: developing self-relevant aspirations with appropriate scripts; increasing the personal and economic realism of aspirations; coping with goal-blockages; creating employment and education opportunities; and processing experiences!. Research to focus on the specific nature of the educational and employment experience was also suggested.

Masters thesis, Memorial University of Newfoundland.

abstract: The continental margin of Newfoundland is made up of a series of interconnected, deep, Mesozoic sedimentary basins. Between the Cumberland Belt Transform Zone and the Charlie Gibbs Transform Zone the Avalon terrane is dissected into a 450 km wide track of extensional ridges and grabens collectively known as the Orphan Basin. From both a tectonic and a petroleum potential point of view the basin can be divided into an older (Late Triassic - Early Jurassic) sub-basin known as the East Orphan Basin and a younger (Cretaceous) sub-basin known as the West Orphan Basin. The Orphan Basin is an underexplored area and few studies have been completed on the structural, tectonic and stratigraphic framework of the area. -- Seismic stratigraphic analysis of the basin identified six major sequence boundaries ranging in age from pre-Mesozoic (Seismic Basement) to present (Water Bottom) and four Cretaceous sequences were identified, mapped and described. Four fault families were defined within the study area on the basis of their regionality, timing and duration of movement and depths of detachment: the Basin Bounding Fault Family, the Basement Involved Fault Family, the Sedimentary Fault Family and the Transfer Fault Family. -- Based on the mapping of the Cretaceous sequences and the orientations of major faults seen in the study area, the Orphan Basin can be divided into three distinct tectonostratigraphic regions. From west to east they are Areas A, B, and C. Areas B and C were affected by the Late Triassic - Early Jurassic Tethys Rift and the Late Jurassic - Early Cretaceous Atlantic Rift. Area B was reactivated for a third time with the Aptian - Albian Labrador rift that caused uplift and inversion of large structures in this area. Area A was predominantly affected by the Aptian - Albian Labrador rift and has Early and Late Cretaceous basin fill.     The orientation of the major basement involved and basin bounding faults in the basin show a counterclockwise rotation from east to west as the rift propagated landward. The oldest faults (located in Area C) have a NE-SW orientation in line with the Tethys rift while those faults in the younger Area A have an approximate N- S to NNW-SSE orientation in line with the Labrador rift. -- A proven petroleum system has not been identified in the Orphan basin; however, due to the timing of rifting, two different petroleum systems are proposed for the East Orphan and the West Orphan basins. Considering all the elements and processes required for a working hydrocarbon system, the most likely plays within the East Orphan Basin are: an oil prone source rock equivalent to the Egret Member of the Rankin Formation; reservoirs of Early Cretaceous stacked sandstones, a seal of Late Cretaceous and Tertiary shales; large structural traps in the form of drape over horst blocks, extensional anticlines and rotated fault blocks of Late Jurassic - Early Cretaceous age. The petroleum system for the East Orphan Basin is likely analogous to that of the Jeanne d'Arc Basin. In the West Orphan Basin the most likely plays are: Late Cretaceous and early Tertiary organic rich shales equivalent to the Bjarni and Markland Formations in the Labrador basins; reservoirs made up of Late Cretaceous and early Tertiary sands; seals of thick Nautilus or Banquereau equivalent shales; structural, stratigraphic and combination traps, most likely basin margin fans pinched out updip or draped over some form of structure. The petroleum system for the West Orphan Basin is likely analogous to that of the Labrador basins.

abstract: A software model was built to investigate the feasibility of reducing the dimensionality of the representation of speech for speech recognition. The model was based on a model of human audition developed by Searle in hardware, the characteristics of which closely match physiological characteristics obtained experimentally from the human auditory system. The model consisted of 16, one third octave bandpass filters followed by envelope detectors, the outputs of which were then subjected to the linear discrete cosine transform in an attempt to reduce the data to a small number of perceptually important dimensions. Several signal processing techniques were investigated to reconstruct the filtered, detected and transformed speech to permit effective intelligibility testing. Most of the work done was qualitative and the methodology concentrated on testing the model rather than the theory. A test sentence produced by a male and female speaker was transformed using the model and the transformed speech was reconstructed. Informal testing with a few experienced listeners suggests that it might be possible to recognize speech with as few as three out of the sixteen channels. This study confirms the value of realizing the models in software. Although the model is not real time it was far easier to modify than the comparable hardware models.

abstract: This thesis features a review of the early Holocene period in Maritime Provinces prehistory. A reexamination of regional collections, paleoenvironmental evidence, and comparative archaeological information from the State of Maine has lead to the development of a new model for early Holocene occupation of this region. The new model replaces the former Great hiatus” model which proposes a 5000-year gap in the cultural sequence (10,000-5000 B.P.). Implications of the model for interpreting regional cultural development, and for future research strategies are also addressed.

abstract: The 1860’s were important years in the history of Newfoundland. In 1861, six years after the establishment of responsible government, Newfoundland was torn by one of the worst periods of civil strife in her history following the Governor’s dismissal of his Liberal, and predominantly Roman Catholic, Government and their replacement by a Protestant Conservative Executive Council. Before the sectarian and political turmoil had completely subsided, the question of confederating with the other British North American colonies was introduced into local politics. In 1865, partly as a result of the agreement among leaders of both parties on confederation, a coalition government, the first to include Liberals and Conservatives was formed. From that time the principle of the distribution of patronage and administrative offices in proportion to the strengths of the religious denominations was put into operation—a system which has proved over the years to be a workable solution to the problem of minimizing denominational jealousy. Confederation was the dominant issue until 1869 when the colony decided, by a general election, not to join the Dominion of Canada. Problems relating to French rights in Newfoundland remained unsettled and disputes were likely to erupt at any time as the demand for greater Newfoundland control over the French Shore increased. The first determined and successful effort to establish more effective control over the large dependency of Labrador was made in the 1860’s. Throughout most of the period the colony was experiencing an economic depression and this resulted in serious financial problems for the Government. – The first chapter of the thesis gives the political and economic background of the period and summarizes the chief events from the introduction of responsible government in 1855 to the dismissal of the Liberal administration in 1861. It stresses the political and sectarian bitterness, the instability of the economy, and the problem of French rights in Newfoundland. The next chapter traces the events which led to the dismissal of the Liberal administration by the Governor and the third describes the strife which followed that action. The fourth and sixth chapters deal with the administrations of Hugh W. Hoyles and F.B.T. Carter. They are, in the main, concerned with economic and financial matters, legislation, party politics, the French Shore, and Labrador. Two chapters are devoted to confederation. The first deals with Newfoundland participation in the Quebec conference, the reaction of the public and the Legislature of the colony, and the postponement of a decision during the sessions of 1865, 1866, and 1867. The second chapter on confederation deals with the adoption of terms of union by the Newfoundland Legislature in 1869, negotiating with the Canadian Government, and the hard fought general election of that year in which the anti-confederates were victorious. Many of the political, economic, and social problems confronting Newfoundland in 1861 remained unsolved in 1869, but the thesis shows that there was, nonetheless, progress in the colony during these years and that there was a most important increase in political stability.

abstract: It is essential for the reader to bear in mind that the F.P.U was not only a union, but from its beginning adopted an important role in commerce and politics.  It had also functioned as a municipal council in the many settlements throughout the east and north-east coasts, and had many of the characteristics of a fraternal society. -- This monograph is an attempt to trace the growth of the F.P.U. in each branch of its development, with particular emphasis on the factors which made such a movement possible and explanations for its ultimate failure. However, before attacking the primary problem, the writer has devoted considerable effort to the background history of the pre-union period in an attempt to make clear to the reader the conditions which existed in Newfoundland before the movement began. -- The major problem can be clearly divided into several minor ones. Of primary importance is a study of the inception and development of the union itself, with special reference to why it failed to expand beyond the east and north-east coasts, and to the aims of the union as initially planned by the founder. -- In the field of politics each of the following topics has been considered:  the original political aims of the F. P. U., its role in politics before the formation of the Union Party, the “Bonavista Platform”, the decision to coalesce with the Liberal Party in 1913, the election of 1913, the record of the Union Party in the House of Assembly before 1917, the National Government (1917-1919), the second Liberal-Union coalition, and the role of the union candidates while part of the Government. -- Detailed study has been given to each of the commercial endeavours of the F.P.U. and considerable effort devoted to the effects this activity has on the movement itself and on the country generally.  In this respect particular attention has been given to the change that took place in this commercial policy from 1903 to the 1920’s. -- The writer has also tried to create a verbal picture of W. F. Coaker. Included is a chronological biography and also a detailed character analysis. Particular emphasis has been given to the noticeable changes which took place in his character from the year he founded the F. P. U., (1908), to his retirement in 1932. -- Finally, in the conclusion an attempt has been made to show how the F.P.U. compared with similar development in other parts of the world at the same time, and how it has left a mark on the life of the country that in many respects is still apparent today.

abstract: Logging pressures on boreal forests have increased in recent decades and carry with them increased concerns for wildlife and habitat conservation. Buffer strips mitigate some of the negative impacts of logging on riparian habitat and associated wildlife. Given the widespread use of buffer strips, the subsequent increase of clear-cut/forest edge, and the decline of many forest birds. I investigated how buffer strips and habitat edges influence avian nesting success. Nest predation is the most common cause of nest failure among song birds. Therefore, artificial nests are a useful research tool for investigating the influences of habitat alteration on nest predation. Japanese Quail (Coturnix japonica) eggs are often used in artificial nest studies, although these eggs may be too large to detect predation by small mammals. My primary objectives were to determine 1) if nest predation differs between intact riparian forest and a) buffer strips and b) clear-cut forest edges, and 2) if Japanese Quail eggs are appropriate to use in artificial nest studies in western Newfoundland. -- Artificial tree and ground nests (n = 150 in 1996, n = 420 in 1997) with Japanese Quail eggs were used to measure nest predation in study blocks (k = 5 in 1996, k = 7 in 1997) that included buffer strips, intact riparian forest, and clear-cut forest edges. The second experiment used artificial ground nests (n= 180) with Chinese Painted Quail (Xexcalfactoria chinensis) eggs and Japanese Quail eggs to measure the influence of egg-size on ground-nest predation in buffer strips (k = 4) and intact forest sites (k = 5). The influences of buffer strip width, nest visibility, and distance of the nest from the nearest edge on nest predation were measured and nest predators documented. -- Nest predation was significantly different and extremely variable between study sites in both experiments suggesting that local presence of predators may be influenced by site-specific conditions, rather than specific types of habitat alteration. Nest predation did not differ between intact riparian forest (55 %) and a) buffer strips (41 %) and b) clear-cut forest edge (50 %). Nest predation significantly increased with increasing buffer strip width (13-38 m). However, the conservation value of buffer strips is likely to increase with width due to low increases in predation, greater abundance of Neotropical migrants, and lower proportional windfall rates in wider buffer strips. Nest predation was higher on tree nests than on ground nest in both years, and nests with greater visibility were more successful than exposed nests. Gray Jays {Pensoreus canadensis) and red squirrels {Tamiasciurus hudsonicus) were the only identified nest predators. Gray Jays preyed significantly more on tree nests than ground nests while red squirrels preyed equally on both nest types. Egg- size did not influence predation. I conclude that predation is influenced by site- specific factors and that Japanese Quail eggs are appropriate for artificial nest studies in western Newfoundland.

Masters thesis, Memorial University of Newfoundland.

abstract: This report provides an overview of an educational psychology internship at the College of the North Atlantic. The placement component includes a description of the internship setting, specific goals and objectives, a description of the internship activities, as well as the intern's personal reflections on the internship experiences. The research component focuses on the transition experience of older, “reentry female college students as compared to more traditional age, early entry female college students as they complete the first year of their program. Anticipated differences between reentry and early entry students in their reasons for entering college, the personal and institutional barriers they experienced in making the transition, and the supports they received throughout the transition, were not supported by the research findings. However, concerns were raised regarding the high numbers of students in both groups that had considered dropping out of their college program, as well as the high numbers that worried about competition with other students. Recommendations and suggestions for future research are included.

abstract: This thesis presents results of investigative experiments using constant temperature anemometry to measure three dimensional flows in a towing tank. A three dimensional probe was configured from three single 45° hot-film probes mounted with their sensor plane at 120° to each other. Presented are the calibration data for each of the single sensors for variations in velocity, yaw and pitch angles as well as the performance of the three probes when mounted in close proximity to each other. The calibration data of each sensor was fitted by a two parameter non-linear polynomial in velocity and yaw angle. The probes were insensitive to variations in angle of pitch. A nominal wake survey was done with the three dimensional probe on the Institute of Marine Dynamics ship model No. M445, the model of a modern fishing vessel form. The results from this wake survey are compared with the results from an existing pitot tube wake survey done for this model. The spectrum of turbulence in the wake is presented.

abstract: The striped wolffish (Anarhichas lupus) is a candidate species for commercial aquaculture m Newfoundland. It possesses a number of characteristics which facilitate culture, such as large eggs, well developed larvae which readily accept formulated feeds and tolerance to low temperatures. Little research has been conducted to determine the dietary requirements of the juvenile wolffish or the optimum stocking density and feeding frequency. The effects of three feeding frequencies (two meals/day, one meal/day and one meal/two days) on various growth parameters were investigated. Mean meal size was significandy and inversely affected by the feeding frequency. In addition, total feed consumption over time was directly affected by the meal frequency. The specific growth rate (SGR) was not adversely affected by the decrease in meal frequency or feed intake. Feed and labour costs, therefore, may both be reduced by lowering the frequency, without compromising the SGR. The stocking density also affected the feed consumption. The smallest mean meal size (3.990 mg/g fish) was consumed by fish stocked at 80 g/L. The largest meals were consumed by fish stocked at 50 g/L (4.955 mg/g) while the meal size of fish stocked at 20 g/L was in between these values. The feed conversion ratio (FCR) decreased significantly when the stocking density was greater than 50 g/L and the protein efficiency ratio (PER) was significantly higher when the stocking density was greater than 50 g/L. The dietary energy balance, expressed as the protein energy:total energy ratio (PE:TE) had a significant negative influence on the intake of feed, lipid and energy. As the PE:TE increased, the feed, lipid and energy intakes all decrease significandy. The PE:TE had no significant impact on the FCR or PER at either constant 9 °C or ambient temperatures (13.0 °C to 2.0 °C). The production cost (based on feed costs per kilogram of fish produced) was not significantly affected by the PE:TE or by decreasing temperatures.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Using gelatin substrate gel zymography, several activities were detected in sea urchin eggs and in various stage embryos which ranged in apparent molecular masses from 27.5 k to 86.9 k. We have purified and characterized the prominent 41 kDa collagenase/gelatinase activity from the sea urchin egg. The native molecular mass was 160 kDa, suggesting a tetrameric structure. Upon dissociation of calcium, enzyme activity was lost and this inhibition was found to be reversible. Reconstitution of activity occurred with an apparent dissociation constant of 3.7 mM. Up to 200 mols of calcium bound per mol of the 41 kDa subunit. Two classes of calcium binding sites were detected with dissociation constants of 0.5 and 5 mM. Amino acid analysis of the 41 kDa collagenase/gelatinase revealed that it contained twenty-four mol percent carboxy and carboxyamide residues which can function as weak calcium-binding sites. In the presence of calcium no secondary or quaternary structural changes were detected in the collagenase/gelatinase. The 41 kDa species had collagen-cleavage activity which appeared to be specific for echinoderm collagen, and a less specific gelatin-cleavage activity toward both invertebrate and vertebrate gelatin. The kinetic parameters, KmVmax and the ratio kcat/Km determined for the collagenase and gelatinase activities using peristome collagen and gelatin, were similar to those reported in the literature for vertebrate collagenase and gelatinase activities. Immunolocalization was carried out to determine the subcellular localization of the 41 kDa collagenase/gelatinase in the unfertilized egg and in various stage embryos. The 41 kDa collagenase/gelatinase was found to be stored in several compartments in the egg: cortical granules (located along the periphery of the egg), and yolk granules and yolk granule-like structures (dispersed throughout the cytoplasm). Following fertilization, the 41 kDa species was detected in both the apical and basal extracellular matrices, the hyaline layer and basal lamina, respectively. In addition, the cytoplasmic storage compartment(s) retained a portion of their label into the gastrula stage. We followed the development of embryos in the presence of the 41 kDa collagenase/gelatinase and in the presence of the anti-41 kDa collagenase/gelatinase antiserum. In both studies embryos developed normally to the mesenchyme blastula stage, while subsequent development was retarded. The process of gastrulation was delayed and embryos failed to develop into plutei with well developed arms.

abstract: Numerical simulation techniques are widely used to investigate the behavior of submarines during the design stage. The accuracy of these techniques depend upon the accurate determination of the hydrodynamic coefficients for the model. -- The Marine Dynamic Test Facility (MDTF) is a new-six-degree-of-freedom forced motion testing rig. The rig has the ability to test underwater vehicles in a manner that makes it possible to determine the hydrodynamic coefficients in the equations of motion. Multi-variant linear regression is used to obtain the hydrodynamic coefficients from the experimental data. -- In this study a neural network technique to identify the hydrodynamic model from experimental data is investigated. The technique uses the model trajectory (motion history) to predict the hydrodynamic coefficients of the model. A single MDTF generated maneuver was used to train the network. The trained network was then tested using different maneuvers and the network predictions were compared to the actual MDTF measured forces and moments. -- Results obtained from the neural network technique indicate that the technique can be used to predict the hydrodynamic model of underwater vehicles. The use of this technique can dramatically cut the running costs to conduct experiments on new models.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Pinnipeds have unique phylogenetic and environmental constraints which increase the potential for male polygyny. Most of the land-breeding species are polygynous. Less is known about the mating systems of water-breeding pinnipeds, like harbour seals. Harbour seals have many characteristics which suggest at least a low level of polygyny. The purpose of this study is to determine: 1) if male harbour seals are competing for females by displays and/or territorial maintenance and 2) whether these competitive tactics are linked to siring progeny. -- The paternity results from DNA fingerprinting, using Jeffreys' 33.15 and 33.6 probes on a captive group, indicated that this technique could be used successfully to determine paternities in harbour seals. Observed copulation did not predict male reproductive success. -- Paternity tests were conducted on five adult males and thirteen mother- pup pairs, caught in one study area at Miquelon. Two mother-pups pairs were excluded from the paternity analyses, as they had very low band-sharing coefficients suggesting that these females were fostering pups. Three of the displaying males had fathered pups, while one displaying male and non- displaying male had not. -- The aquatic display behaviour, haul-out patterns and aggressive interactions of nine identified males were video-taped during two consecutive breeding seasons. Site-specific simultaneous displays occurred regularly between neighbouring males, establishing territory boundaries. Males defending more boundaries displayed at significantly higher rates than males with fewer boundaries. These results indicated that displays were for boundary defence and not self-advertisement. Intruder males were forced from haul-out areas through aggressive interactions. Territorial males did father some pups suggesting that there is reproductive success associated with territory defence. Some males were never seen displaying and may have been adopting an alternate mating strategy. The deep channels at Miquelon create physically bounded-water ways through which females and pups must pass. The topography at Miquelon appears to facilitate aquatic territory establishment and the defence of areas proximate to females.

Masters thesis, Memorial University of Newfoundland.

abstract: School libraries, in theory, are an integral and essential part of the school's instructional program, with school librarians involved as teaching partners with classroom teachers. In practice, many school libraries are viewed as frills, existing on the peripheral of the school's instructional program, with the school librarian's role seen as being mainly clerical or technical. This study began as a search to discover why the gap between theory and practice existed, and what, if anything, could be done to close this gap. -- Since it is necessary to fully understand the modern concept of a school library, a chapter is devoted to the development of the modern school library media program. This chapter traces the evolution of the school library by examining the national standards for school libraries which have been published in the United States and Canada, from the first standards of 1918 to the most current standards and guidelines. -- This thesis postulates that a school library is an integral part of the school. To successfully implement a school library media program, it is necessary to understand the nature of teaching and the characteristics of the school which hinder or facilitate such a program. Therefore, a chapter is devoted to an examination of the world of the school. Since the school is part of the school district, and also part of the larger society, this chapter examines conditions in the school, in the school district, and at provincial or national levels. -- Since most schools do not have school library media programs, to introduce such a program is to introduce a major change. Chapter Four examines the process of educational change. It synthesizes the findings on how change occurs in schools and how it affects the individuals involved. -- The final chapter is a synthesis of the findings, relating how the factors associated with the school library media program itself, factors external to the school district, factors at the district level, and factors at the school level contribute to successful implementation of such a change. It discusses implications for anyone interested in introducing a school library media program where none presently exists.

Masters thesis, Memorial University of Newfoundland.

abstract: This report is organized into two parts and describes an internship comprised of two major components. The information in Part I discusses a counseling placement component and Part II presents a program development component. The internship was completed during the period of June to July 1998 at Addictions, Health and Community Services, Western. Western is an addiction treatment center and is located in Corner Brook, Newfoundland, Canada. Part I gives a rationale for the internship, a description of the placement setting, information on site supervision and a discussion of the internship objectives. Part II presents the program development component of the internship. A review of related literature on cocaine addiction was done to provide current research on cocaine treatment interventions. -- The intern's data was gathered from two sources. First, a literature review was carried out to evaluate Western's existing addictions programs. An analysis of selected documents related to this project revealed the number of cocaine abusers arriving at Western. Western's intervention program is based on a biopsychosocial approach, and the review of the related literature indicated an absence of research on the neuro-behavioral approach in the treatment of cocaine abusers. -- The addiction programs at Western were evaluated in order to ascertain both the need for a cocaine treatment program at Western and any factors that would need to be addressed to ensure new program compatibility. New program compatibility had to be maintained to ensure successful integration with or addition to Western's existing addictions programming. Second, pre and post intervention questionnaires were given to Western's clientele and staff in order to gauge clients' perceptions of, and to receive input from Western's treatment team on both the design and compatibility of a cocaine treatment program for Western. -- The findings informed the intern's development and implementation of a cocaine treatment program for Western. As a result of this internship project, a program was developed for Western's future program planning.

Masters thesis, Memorial University of Newfoundland.

abstract: This study investigated the relationships among mothers' and fathers' child development beliefs, role construction, self-efficacy, and grade four children's reader self-perceptions (self-concept, social feedback, physiological states, observational comparisons, and progress), reading achievement (comprehension and vocabulary) and gender. The study consisted of 67 children and 81 parents who had been involved in a literacy project for one year. The study was conducted in the province of Newfoundland and Labrador. -- Five surveys were used in this study: Reader Self-perception Scale (RSPS) (Henk & Melnick, 1995), Gates and MacGinitie Reading Test (Gates and MacGinitie, 1992), Questionnaire for Parents (Oldford-Matchim and Singh, 2002), Parents' Child Development Beliefs (Oldford-Matchim and Singh, 2002), and the Parental Role Construction Survey (Oldford-Matchim and Singh, 2002). The Pearson-Product - Moment Method and ANOVA were used to determine relationships in the data and to identify significant differences in scores. -- Significant positive relationships were found between aspects of children's reader self-perceptions (observational comparisons, progress, physiological states, and total scores) and aspects of children's reading achievement (comprehension scores and vocabulary scores) and children's gender. Boys' reader self-perceptions (observational comparisons, progress, physiological states, and total self-perception scores) were found to be significantly related to boys' reading achievement. Significant relationships for girls' reader self-perceptions and girls' reading achievement were not found to exist. Girls had significantly higher self-perceptions of physiological states, social feedback, total self-perception scores, and self-concept than boys. No significant differences existed between boys' and girls' reading achievement scores. -- A significant positive relationship was found to exist between fathers' self- efficacy and girls' self-perceptions of progress. No significant relationships were found to exist between mothers' and fathers' self-efficacy and children's reading achievement. -- Significant positive and negative relationships were found to exist between mothers' and fathers' parental child development beliefs and children's reading achievement. The one significant negative correlation that existed was between a fathers' child development belief and children's comprehension scores. Significant positive relationships were found to exist between mothers' child development beliefs and aspects of girls' and boys' reading achievement, as well as fathers' child development beliefs and girls' aspects of reading achievement. A variety of significant positive relationships were also found to exist between mothers' and fathers' child development beliefs and aspects of girls' and boys' reader self-perceptions. -- Significant differences were found between mothers' and father's self-efficacy; a child development belief stating that children learn to read better when parents and teachers respect their curiosity and questions about stories, print and reading; and between boys' and girls' perceptions of physiological states, social feedback, total self- perceptions scores and general self-concept. -- This study has revealed that parents' child development beliefs, parental role construction, parental self-efficacy, children's reading achievement, children's self- perceptions of reading and gender are related. This study has provided an understanding of the variables that are related to children's reading achievement. It has also revealed important information concerning the impact parents' beliefs, roles and self-efficacy has on their children's reading achievement and how their children perceive their own reading ability.

abstract: This thesis deals with the correlation structure of annual peak flow series in detail. The thesis is in divided into four major parts. -- Part one takes a closer look at the correlation structure of annual peak flow series at two scales: scale of one that measures short-term behaviour by the lag-one autocorrelation coefficient, r(1), and scale of n, that measures long-term behaviour by Hurst's K. It is shown that there are significant correlation and dependence between Hurst's K. and r(1) for both observed data and data from Monte Carlo experiments which imply that short- and long-term behaviour cannot be treated separately as is current practice. -- Part two suggests a new approach for quantitatively describing long-term correlation that is rooted in an independent series. The results indicate that long-term correlation rooted in a short-term independent series can be quantitatively estimated, and the simultaneous occurrence of high values of Hurst's K and low values of r(1) is, in fact, not an uncommon phenomenon. A new method of testing for long-term correlation that takes the short-term correlation into account is developed. -- Part three further looks at peak flow correlation structure across scales based on the perspective of fractal geometry. A family of probability-scale-threshold curves which contain more information about the correlation structure of peak flows, are constructed and the scaling behaviour of peak flow series is explored. -- In order to take serial correlation into account in flood risk analysis, the concept of scaling plotting positions (SPP), is developed in part four. It takes scaling behaviour of peak flows into account and develops a new plotting position formula in estimation of future floods. The results of Monte Carlo simulation showed that the estimated quantiles of SPP are more efficient and robust when compared with current estimators of flood quantiles. -- The study presented in this thesis has provided a view of the correlation structure of peak flows across scales so that flood risk can be better estimated.

Masters thesis, Memorial University of Newfoundland.

abstract: Advocates of parental involvement recognize the tremendous potential that exists when the home and school cooperate but effective partnership is actually minimal, due mainly to the need for useful, organized information on parental involvement This project monitored the development of a Romeo and Juliet unit of work to two grade nine classes at the John Cabot Junior High (pseudonym). Individualized activities were introduced to seven low achievers and, through a home-school collaborative effort, an attempt was made to improve the active learning of these students. -- The results of this project indicated that both parents and students found the unit of work to be satisfactory and that the strategies introduced were adequate for meeting the project's expectations, and thus increasing the students' school success. Basically the problems that occurred related mainly to ineffective communication between the parties concerned, but once the parents realized that the focus of the involvement was their children's success, they were willing to work through any obstacle and view it as an inevitable inconvenience in any learning experience. It was noted that the students, though there was a significant improvement in their learning skills, did not generally view the home-school cooperation as a partnership but as a teacher-directed initiative that would ensure their homework was completed.

Societal, educational researcher and student views of the basic skills issues are presented. Acknowledging that each student may learn in a different way and at a different rate, the performance and mastery type students are examined metacognitively. A number of sample pedagogical practices that reflect the philosophy of this project have been chosen for presentation. A coordinate geometry project, moulded with ideas of mathematics learning as advocated by the Atlantic Provinces Education Foundation (APEF), is presented which reflects the conviction that both constructivist and traditional ideologies of mathematics should be a balanced part of student learning.

abstract: Purpose: The purpose of this study was to develop and validate a symptom-based outcome measure for clinical trials in nonulcer dyspepsia (NUD). -- Methods: Patients referred to the GI outpatient clinic with chronic upper abdominal pain were approached for this study. Participants with normal endoscopy who met the inclusion criteria were enrolled and classified into standard subgroups of NUD. The ulcerlike subgroup received acid suppressive therapy and the dysmotilitylike subgroup received prokinetic agents. -- Each subject completed a questionnaire at the initial visit (T1), one week later before treatment (T2), and after one month of treatment (T3). Each subject selected the symptom most important to them. The frequency and severity of the selected symptom was recorded as was a global assessment by the subject of their overall status. Other data recorded included a physician global assessment, the subject's and physician's impression of change in symptoms with treatment, and the subject's antacid use. -- Results: Forty-four subjects were enrolled. The primary outcome measure of the study was the product of the selected symptom's frequency and severity. Instrument reliability was assessed by Spearman rank correlation r=0.85 and the intraclass correlation coefficient = 0.83. -- Good correlation between the measure and patient global assessment (lrl=.596) and between the measure and patient assessment of treatment response (Irl=.584) was noted. The physician global assessment was moderately related to the measure (lrl=.437). Some relationship was seen between the measure and physician assessment of treatment response (lrl=.329). There was no relationship with change in antacid use (lrl=.143). -- Conclusion: The main measure was reliable in untreated subjects and responsive in subjects who responded to therapy. This measure also appeared to be valid. The method of combining frequency and severity of the subject-selected symptom into a product was shown to be a useful means of assessing treatment effect in NUD patients. This study documents a reliable, responsive, and valid new outcome measure for use in clinical trials of NUD.

format: application/pdf video/mp4 application/pdf application/pdf application/pdf

abstract: This Master's thesis focuses on the narratives of four Muscovite women belonging to the Russian intelligentsia, using life history, social memory and visual anthropology methods. The Russian intelligentsia was often seen as having served a contradictory position as both conformist and oppositional to the Soviet regime. However, after the collapse of the Soviet Union in 1991, many academic publications have questioned whether the role of the intelligentsia remains politically relevant in post-Soviet Russia. Using life history techniques to probe participants' memories of various Soviet and post-Soviet eras and focusing on the period of the perestroika between 1985 and 1991, the author problematizes various binary definitions of the role of the intelligentsia, proposing to view membership as a negotiation of meanings, memories and contestations of belonging. A feature-length ethnographic film produced during the period of fieldwork in Moscow and based on participants' memories is appended to the thesis.

abstract: Marine fisheries worldwide have relied heavily on single-species assessment models for evaluating fish stock status, and as a basis for fisheries management. The collapse of numerous fish stocks around the world, notably the Northern Cod stock of the northwest Atlantic, has many fishers, resource management experts, non-governmental fisheries organizations, academics and other management organizations questioning the efficacy of traditional evolutionary look and application to an ongoing commitment single-species approaches. Consequently, resource management institutions, particularly Regional Fishery Management Organizations, are moving to a more integrated and inclusive system - the ecosystem-based approach to fisheries management. -- The genesis and evolution of the ecosystem approach through to its eventual application in modern fisheries management is described, as is the effort and success organizations have experienced in advancing what is inarguably a complex and elusive concept to apply in practical terms. The analysis of a broad range of past international agreements, conservation frameworks and conventions illustrates how the ecosystem-based approach to fisheries management evolved from a loosely defined objective to what is effectively a new "tool" for fisheries management practice. Two case studies of contrasting fisheries management regimes will demonstrate how the ecosystem-based approach is being adopted and applied in a modern context.

abstract:
The purpose of the study was to analyze the effect of inversion with wave motion on the
functioning of cardiovascular and neuromuscular systems. Cardiovascular system was assessed
by measuring the heart rate response and neuromuscular system was analyzed by measuring
maximum voluntary contraction (MVC) force and electromyography (EMG). Force production
and electromyographic (EMG) activity for elbow flexors and knee extensors were measured
along with muscle activation of trunk and abdominal muscles. Heart rate was measured before
and after each experimental procedure. All the parameters were tested in upright and inverted
seated position with wave motions. Both positions were combined with 3 sets (pitch, roll and
random, all combined with heave) wave motions and were selected randomly. Pitch, roll and
heave are types of wave motion, where random was combining all the three types of wave
motion together. Each experimental procedure lasted I minute and subjects performed two
isometric MVCs for the right elbow flexors and right knee extensors at beginning and at the end
of one minute. Results showed that wave motion induced significantly less knee extension MVC
force (Pitch = 8%; Roll = 13.4%; Random = 13.5%, P < 0.0001) and significant less elbow
flexors MVC force (Pitch = 21.1 %; Roll = 26.7%; Random = 25.1 %, p < 0.000 I). A main effect
for time showed that there was a significant drop in EMG activity with the second MVC
(compared to first MVC) for vastus lateralis (15.4 %, p = .0024). biceps brachii (11.7 %, p =
05). lower abdominal structure (LAS) and external obliques muscles (12.5 %. p = .034). A
significant increase in heart rate (18.1 %.p=.OOOI)wasseenpostexperimentalproceduresin
upright seated position compared to before the start of the procedure. The results were evaluated
by keeping position, time and wave motion as factors. Tlie aforementioned results suggest
significant neuromuscular impairments and heart rate responses with wave motion and inversion
combined over time. The results of this study provide both basic physiological mechanisms and
applications to life threatening situations such as submerged helicopters subjected to wave
motions as well as overturned vehicles among other situations.

abstract: Chitin, chitosan, and their monomers were investigated as renewable feedstocks to produce useful chemicals. These biopolymers are readily available, cheap, non-toxic, and environmentally benign. They are produced, degraded and reabsorbed in nature. They could in part replace depleting resources, such as fossil fuels, in useful chemicals production. To this end, microwave heating, catalysts and additives have been investigated. Factorial designs (FDs) were used as an effective approach to optimise the reaction conditions. Reaction products obtained were extracted using ethyl acetate and their amounts were determined using GC-MS. Although these biopolymers are difficult to solubilise, useful products were obtained in water under the reaction conditions described herein. Levulinic acid (LA) and 5-hydroxymethylfurfural (5-HMF) were produced from chitosan using SnCI₄5H₂O which can be handled with ease and is a relatively inexpensive reagent. The medium for this reaction (water) is non-toxic, nonflammable, and readily available at low cost. The chitosan reaction mixture was heated to 200℃ under microwave irradiation for 30 min in a closed vessel. Two different  reaction concentrations were tested; the "concentrated reaction" yielded 23.9 wt% LA, and the "diluted reaction" yielded 10.0 wt% 5-HMF. Each reaction has a high selectivity for the desired product; chitin was also able to produce LA under the concentrated reaction conditions (12.7 wt%), This proof of concept study showed that amino-saccharides can be used as feedstocks for levulinic acid and 5-hydroxymethylfurfural typically obtained from cellulosic biomass. It was discovered that a nitrogen containing compound 3-acetamido5-acetylfuran (3A5AF), could also be produced from chitin and chitosan in small amounts. However, by using N-acetylglucosamine (NAG) instead of chitin, a higher % yield of 3A5AF could be obtained, possibly due to limitations in the depolymerisation process of chitin. The transformation of AG was dependent on the supplier of this amino-sugar and it was discovered that B- and CI-containing impurities in one source were likely aiding the conversion process. Therefore, AG was reacted in the presence of two additives: NaCI and B(OH)₃. After solvent-screening, the reaction was optimized in dimethylacetamide (DMA). The reaction mixture was heated using microwave irradiation to 220℃ for 15 min. 3A5AF production was quantified using GC-MS. The % yield of3A5AF was determined to be ca 58. This study showed that this compound could potentially be produced cheaply and is a potential renewable feedstock for other N-containing molecules e.g. proximicins A, B and C (antibiotic and antitumor drugs). As an alternative to this method, a procedure was developed in ionic liquids (ILs) to produce 3A5AF. 3A5AF could be obtained in up to 60% yield by heating AG in the presence of NaCI and B(OH)₃. In summary, the research described in this thesis demonstrates the potential of fishery waste to produce valuable chemicals (LA, 5-HMF. and 3A5AF). Mechanisms of product formation are also proposed and discussed.

abstract: The generalized linear model (GLM) is a class of versatile models suitable for several types of dependent variables. GLMs are commonly used to model maturity data. Generalized linear mixed models (GLMM) are a useful extension of the GLM with the addition of random effects. GLMMs have previously been used to improve the estimates of the maturities and provide better predictions of maturities in the near future. Dowden (2007) used GLMMs to model a Atlantic cod maturity data set. His research found that GLMMs improved maturity estimates and forecast accuracy over the GLM commonly used. The results also revealed potential year effects in the cod data. This may be due to actual year effects or some other source such as sampling error. In general it is unknown whether year effects are present in a data set. In this practicum we first provide an overview of Dowden's results. Then we conduct a simulation study to investigate which GL 11M provides the most accurate estimates of the simulated maturities and parameters under a range of simulation factors including the presence of year effects. The two GLMMs used to model the simulated data are an autoregressive (AR) mixed model and a AR mixed effects model with random year effects (AR YE). In this research we find the AR YE model appears to be more appropriate than the AR model when the presence of year effects are unknown. The AR YE model's estimates are similar or better than the AR model's and it also tends to be either as efficient or more efficient depending on the presence or size of the year effects.

abstract: Ce mémoire est une étude des relations entre les Français et les colons britanniques (surtout irlandais et anglais) au Petit Nord du French Shore de Terre-Neuve pendant les années 1850 au niveau politique, social et économique. Les luttes de la colonie au sujet du «problème» ou de la «question» du French Shore à cette époque encadrent cette analyse. Les 1 086 colons, habitant cinquante havres entre Cap Normand et Cap Saint-Jean énumérés dans Ie recensement de 1857, constituent la population britannique étudiée. En 1859, une commission internationale sur les pêcheries de Terre-Neuve fait Ie tour de cette côte et dresse les procès-verbaux des interrogations de treize pêcheurs britanniques et dix pêcheurs français dans ces havres. On prend des indications verbales de six autres capitaines français en séances. Ces procès-verbaux forment un point de départ pour I'analyse des relations franco-britanniques dans cette région. La correspondance des Commandants de la Station navale française avec Ie Ministre de la marine et des colonies est aussi révélatrice. Les rapports des officiers navals britanniques donnent la perspective anglaise. Plusieurs conclusions émergent de cette étude. L'autorité des Français domine sur ces côtes. La réussite de la campagne de pêche morutière à Terre-Neuve, par contre, nécessite la présence de colons. Les gardiens britanniques remplient ce rôle. lis deviennent, par conséquent, les gardiens de la souveraineté britannique sur Ie French Shore. L'hiver est la saison d'une grande industrie lucrative - Ia chasse au phoque - une industrie qui se déroule sans préjudice a la pêche française estivale et qui permet aux colons de subir l'hégémonie des Français pendant cette saison. Les relations symbiotiques, Ie partage d'une vie isolée et hasardeuse pendant des générations de suite par les mêmes familles  françaises comme britanniques,  encouragent la compréhension et la sympathie entre les ressortissants des deux nations. En dépit du manque d'institutions civiles et judiciaires, la religion devient un élément de cohésion sociale.

abstract: In this work, a fast parasitic-aware synthesis approach of CMOS analog and RF circuits is presented. Traditionally in layout-aware synthesis approaches, the optimization of analog and RF circuits is attained by two separate stages. The circuit sizing stage which is mostly implemented by using some evolutionary algorithms along with certain commercial off the shelf simulators is followed by layout generation, extraction and verification. This loop continues until convergence is found. In this thesis, a fast parasitic-aware method, which considers the circuit performance constraints and layout induced parasitic simultaneously within a concurrent phase of circuit synthesis by using convex optimization problem, is proposed. The proposed methodology is used to optimize and verify the performance of five high performance analog circuits and two RF circuits in two different CMOS technologies. The synthesis time is found to be under a few seconds and the experimental results demonstrate the high efficacy of this fast parasitic-aware synthesis approach.

abstract: The ion transport properties and the accompanied charge compensation mechanisms of electrochemically prepared conducting polymers have been investigated by cyclic voltammetry and impedance spectroscopy. The conducting polymers considered in this work are polypyrrole and polyfluorenone in which p-doping and n-doping were probed, respectively, in various electrolyte solutions. Both polymers were prepared by anodic coupling polymerization using various techniques: potentiodynamic, potentiostatic, and galvanostatic. Chemical modifications of the two polymers have been achieved under optimized conditions to obtain high quality, stability, and interesting electrochemical properties, such as charge capacity and electroactivity, of the deposited films. These modifications can facilitate the understanding of ion transport in conducting polymers in order to enhance their use in many potential applications, such as batteries, fuel cells, flexible displays, and other electrochemical devices. The surface morphology and elemental analysis for the polymer films were characterized by scanning electron microscopy and energy dispersive X-ray emission, respectively. -- The rate and mode of ion transport in conducting polymers have been controlled using dopant anions of various sizes and charges during film deposition. Cyclic voltammetry and impedance spectroscopy have been used to probe the mode of ion transport (anion or cation transport) using scan rate dependence and potential dependence, respectively. An enhanced anion transport rate was achieved using large univalent dopant anions, while an enhanced cation transport rate was achieved using a polyanion electrolyte during film deposition. Polypyrrole film modifications have been achieved chemically using various additives during film deposition and electrochemically by overoxidation at mild potentials before film degradation. Deactivation and reactivation of the polyfluorenone films were investigated by cyclic voltammetry in which deactivation was achieved for modified and unmodified films by continuous cycling during n-doping. However, reactivation of a deactivated film was only achieved following modification with a steric stabilizer, polyethylene glycol, by polarizing the film at positive potentials.

abstract: Microwave repeaters are one of the main energy consumers in the telecommunication industry. These repeaters are powered using diesel generators and batteries, particularly when they are located in remote areas. Diesel generators require a higher maintenance cost and for remote sites this cost will be more due inaccessibility and spare transportation to the added its operating cost. This thesis researches optimal sizing and compares a non-renewable energy system (existing system) and a renewable energy system (proposed system) for a remotely located telecommunication site in Mulligan, Labrador in Canada. The current system is operated using a diesel generator and batteries and the proposed system is expected to integrate a hybrid wind and solar energy system with the existing diesel generator and batteries. Hybrid Optimization Model for Electric Renewable (HOMER) software is used to obtain the most feasible configuration of a hybrid renewable energy system. Secondly, the proposed hybrid system is modeled in Matlab/Simulink and results are presented to demonstrate the system's performance. Finally, a real time supervisory controller has been designed and implemented for a small scale hybrid power system at Memorial University of Newfoundland. The overall reliability is guaranteed since there are two backup sources; battery bank and diesel generator. The results show the hybrid renewable energy system is cost effective. The proposed system significantly reduces the running time of the diesel generator and this helps to reduce the emission level. Moreover, it is expected that the proposed system will help the BellAliant Company to provide uninterrupted power for their sites in remote areas of Labrador.
