abstract: Most research addressing unequal educational opportunity as regards to fiscal equity and adequacy has largely focused on disparities between school boards and to some extent individual schools in the same province. Disparities among provinces, a problem less emphasized by the research in Canada, offer a significant lens through which public education funding can be examined. A comparative rather than individual province analysis provides policy makers with rich information that can assist funding policy comparisons and decisions. -- This study analyzes fiscal equity and perceptions of adequacy across ten provinces for the years 1996-2006. The results of the study reveal that the disparities have disproportionately affected the Atlantic provinces. Furthermore, the study shows that inter-provincial disparities in spending are linked to provincial resource endowment, thus highlighting the need for a federal role in ameliorating inter-provincial disparities in educational standards. Further analysis of the research revealed that there has been an increased emphasis on the perceptions of adequacy and that across most provincial jurisdictions; policies are geared towards student attainment of performance standards.

type: Thesis NonPeerReviewed

abstract: The incubation of rat jejunal slices in Kreb’s-Ringer bicarbonate buffer (RRS) resulted in a time dependent release of soluble sialyltransferase (STase) into the incubation medium for up to 6 h. However, the STase released was susceptible to proteolysis and in order to measure the STase activity released there was a requirement for either heat-inactivated serum, α₁ proteinase inhibitor (A1PI) or α₂ antiplasmin in the incubation medium. Trypsin and plasmin activities higher in medium obtained from KRB incubations, compared to incubations where KRB supplemented with either heat-inactivated horse serum (HHS) heat inactivated rat serum (HRS). -- Addition of heparin to jejunal incubations supplemented with HRS or HHS resulted in decreased STase activity and increased trypsin and plasmin activities in the medium. It was determined that the heparin-binding fraction (HSF) from HHS or HRS was the serum component required in order to measure STase activity in the medium. -- HSF exhibited inhibitory activity towards trypsin and plasmin, but did not inhibit either elastase, thrombin, chymotrypsin, kallikrein or papain. A trypsin-binding protein (TBP) was isolated from HSF by trypsin agarose affinity chromatography. TBP was able to inhibit trypsin and plasmin and on 50s-Page showed a single major band and an apparent molecular weight of 67 kDa. When TBP was used to supplement jejunal incubations, it was as effective as HSF in protecting the STase activity released during jejunal incubations. -- Galactosyltransferase (GTase), which was also released in the soluble form during jejunal incubations, was not dependent on the proteolytic activity of the medium. GTase activity in the incubation medium remained similar whether incubations were carried out in KRB alone or in KRB supplemented with either HHS, HRS, HBF or TBP. Addition of heparin to incubations in either KRB or KRB supplemented with HRS did not cause a decrease in GTase activity, further suggesting that, GTase in contrast to STase was not dependent on the proteolytic activity of the medium. -- Heat-inactivated serum from turpentine treated rats had higher trypsin and plasmin inhibitory activities compared to heat-inactivated control rat serum. When heat-inactivated serum from turpentine treated rats was used to supplement KRB during jejunal incubations there was an increase in the STase activity released into the medium compared to incubations where heat-inactivated serum from control rats was used. In contrast, GTase activity remained similar whether incubations were carried out in KRB alone or in KRB supplemented with heat-inactivated serum from either control or turpentine treated rats. -- Trypsin and plasmin when added individually to a mixture of pure STase (5) and GTase preferentially inhibited STase activity. This effect was observed for both the STases used (α2-6[N] and α2-3 [O]). TBP was able to protect STase against the action of trypsin and plasmin. -- Serum from turpentine treated and control rats when incubated for 4 h at 37°C showed a progressive decline in STase activity over the time of incubation. Trypsin and plasmin inhibitory activities also decreased over the 4 h of incubation. Serum STase, as well as trypsin and plasmin inhibitory activities remained higher in the turpentine treated rats compared to control rats. However, serum GTase activity was similar in both groups. -- In incubations with hepatocytes, STase activity released into the medium was also dependent on the balance between trypsin and plasmin inhibitory / trypsin and plasmin activities of the incubation medium. STase activity was higher in the medium when heat-inactivated serum from either turpentine treated or control rats, HBF or TBP were used as supplements compared to incubations carried out in buffer alone. GTase activity remained similar when incubations were carried out in buffer alone or in buffer supplemented with antiproteases. -- The results indicate that increased STase activity was associated with increased trypsin and plasmin inhibitory activities or decreased trypsin and plasmin activities. This effect was not observed for GTase activity. Soluble STase is susceptible to proteolysis and trypsin and plasmin inhibitors therefore play a key role in determining measurable STase activity.

abstract: In independence setup, the quasi-likelihood estimation of the regression parameters involved in the mean function requires only the specification of the mean and variance function of the responses. In the longitudinal setup, one also has to accommodate the underlying correlation structure in order to obtain consistent and efficient regression estimates. Under the independence setup, when the responses follow an asymmetric distribution with a heavy tail, it has been argued in the literature that the regression estimates using mean regression model can be inefficient as compared to those obtained using a median regression model. Subsequently, the median regression models have been extended to study the asymmetric longitudinal data, but the longitudinal correlation of this type of asymmetric data have been computed using the moment estimates for all pairwise correlations. By considering an autoregressive order 1 (AR(l)) model for longitudinal exponential responses, in this thesis, it is demonstrated that the existing pairwise estimates of correlations under median regression model may yield inefficient estimates as compared to the simpler independence assumption based estimates. It is also argued in the thesis that the quasi-likelihood approach for median regression models may perform the same or worse than the mean regression models unless the data are highly asymmetric such as involving outliers. We illustrate the inference techniques discussed in the thesis by re-analysing the well-known labor pain data.

abstract: The low frequency variability of surface climate over the North Atlantic is described using 55 years of observations from the Comprehensive Ocean-Atmospheric Data set and NCEP reanalysis. Results are based on empirical orthogonal function analysis of sea surface temperature (SST), air temperature, wind, heat flux, and precipitation. The dominant spatial patterns of these parameters and sea level pressure are identified by using canonical correlation analysis. It is shown that the zonal wind and air temperature in the Labrador Sea are strongly correlated with the dominant modes of variability in the atmospheric circulation. The SST anomalies in the Labrador Sea are weakly correlated to the Sea Level Pressure (SLP) dominant modes of variability especially during the decadal periods of warming in the 1950s and the 1990s. It is suggested that the long term variability in the ocean circulation and sea ice at decadal time scale play a major role for the SST in the Labrador Sea during these periods.

Masters thesis, Memorial University of Newfoundland.

abstract: Aspects of the growth of the giant scallop, Placopecten magellanicus (Gmelin), in Port au Port Bay are presented. Von Bertalanffy growth equations have been fitted to selected shell dimensions of the mollusc. It was shown that there is no difference in the growth rate of male and female scallops. When growth rates of the bivalve from different beds within the bay are compared it was found that the largest and most prolific bed had the slowest growth rate. Growth differences are attributed to density-dependent and local sediment composition factors since other environmental influences within the bay are relatively uniform. Fine clay-silt was found to be a less favourable environmental substrate than larger sediments. -- Age and height composition data suggest that the scallop stocks have recovered sufficiently from the overfishing during the early 1950's. -- Gametogenesis and spawning are described. Histological changes accompanying the breeding cycle are also presented. Spawning is protracted, some scallops first spawning in June. This is followed by a major spawning in the fall. The spring spawning is minor and only a few individuals seem to take part. -- Some aspect~ of a heterospecific relationship between the scallop and a unicellular endosymbiotic alga tentatively reported as a zoochlorella are presented. The association is not universal. The presence of adequate light seems to be an essential factor limiting its incidence to shallow-water populations of the species. The effect of the alga upon the molluscan host is discussed. Present evidence indicates that the endosymbiont is a facultative parasite.

abstract: Many industrial processes pose many potential threats to life or environment, especially in case of failure. Hazardous, flammable and reactive materials are often processed at elevated temperatures and pressures. The hazards posed by those materials need to be controlled and managed in order to improve the process safety. Safety Instrumented System (SIS) is a widely recognized tool by a number of industry sectors to prevent those hazards and thus reach the required safety objective. Recently, the process industry has started to realize the significance of SIS. -- Due to the increased process complexity and possible instability in operating conditions, the existing control systems have limited ability to provide practical assistance to both operators and engineers. Therefore, much attention has been focus on suitable designs of system control components. This thesis proposes a new methodology for fault diagnosis, safety function formulation, and to implement safety instrumented system based on real-time monitoring. The methodology is comprised of three stages. The first stage is to model and simulate the target process system according to the observed system behaviors. The second stage is to adopt knowledge-based fault diagnosis technique, which implements the valuable knowledge from the experts and operators as well as a vast databank of information from a variety of sensors, for making optimal decision regarding current state of the process operation. Fuzzy logic is also used in this stage to make inferences based on acquired information (real-time data) and the knowledge. This stage is a fundamental part of the proposed methodology. -- A computer-aided tool, implementing previous two stages, is developed on the platform of G2 expert system platform using GDA (G2 Diagnostic Assistant) components in the third stage. This tool is subsequently used to verify the methodology performance through both industrial and simulated data. -- The proposed methodology is straightforward, flexible and easy to understand. Moreover, the developed fault diagnosis safety function may be utilized in developing various safety instrumented systems.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: This thesis deals with the exploration and the development of Inverse Electron-Demand Diels-Alder (IEDDA)-based methodologies to access 6H-dibenzo[b,d]pyran-6-ones (DBPs) and their application in target-oriented synthesis. Due to its importance throughout this dissertation, the Diels-Alder reaction is discussed in some detail in Chapter 1. This is followed by a discussion of the evolution of research on the IEDDA reaction in the Bodwell group. A detailed investigation of the methods that were developed to produce DBPs is described in Chapter 2 and Chapter 3. Furthermore, the scope of these methodologies was demonstrated by applying these approaches to the synthesis of natural and non-natural products. In this regard, their use in the synthesis of elaborated chiral pyrenophanes (non-natural products) is presented in Chapter 4, and their application in the synthesis of natural products such as Cannabinol and Defucogilvocarcin V is displayed in Chapter 2 and Chapter 5.

abstract: To advance the causes of reducing medical errors and improving the quality of patient care, healthcare is currently going through a period of vast reforms. CPOE (Computerized Physician Order Entry) is one such reform. An important example of CPOE is drug prescription, both of individual drugs and complex regimens, e.g., chemotherapy. By reducing medication errors, CPOE can both increase the quality of patient care and decrease cost. Several types of problems may arise during the design and implementation of CPOE systems. The most obvious of these problems are due to insufficient attention being paid to the nature of existing manual clinical workflows. Much more damaging are subtle problems related to insufficient attention being paid to the nature of the clinical workplace - in particular, the frequent lack of resources, e.g., system administrators and programmers, for ongoing system maintenance and evolution after the system is deployed. --  In this thesis, we will describe the development of an on-line chemotherapy prescription system in which many aspects of system maintenance and evolution can be performed by the system's users. The user-guided operational model underlying this system overcomes many of the problems arising from limited system maintenance and evolution resources in the target workplace. This thesis will also include several discussions of various lessons learned during the development of this system that are applicable to the development of medical informatics systems in general.

abstract: The web graph represents the structure of the World Wide Web by denoting each web page as a vertex and each hyperlink as an arc. The motivating goal behind the research constituting this thesis is twofold - firstly, to model the local structure of the web graph, and secondly, to discover communities of related web pages. -- We study the concept of the neighborhood graph to model the local structure surrounding a particular web page. We analyze some structural and statistical properties of the neighborhood graphs and perform a comparison with the corresponding properties of the whole web graph. In several aspects these neighborhood graphs show a similar characteristic to the entire web graph. Both the indegree and outdegree distribution of a sufficiently large neighborhood graph follow the power law phenomenon. We perform a thematic analysis of the local structure of the Web by discovering authorities and hubs in neighborhood graphs, where the set of authorities and hubs gives a representative flavor on the theme of the page in question. We also analyze temporal evolution of Hyperlinked communities and identify Core communities in neighborhood graphs. -- We devise an algorithm to extract communities solely based on the topology of the Web. Central to our approach is the innovative idea of Iterative Cycle Contraction to discover Web communities comprised of related web pages. The intuition behind this algorithm is that if two pages link to each other then they are thematically related. Successive iterations yield a hierarchical structure of communities and allow us to define a similarity measure between two web pages in the same community by noting at which iteration their corresponding vertices are first grouped into a single vertex. We apply the algorithm to some focused subgraphs of the web graph and evaluate its effectiveness by performing an investigation into the theme(s) of the putative communities that it finds. We find that the algorithm is successful at identifying communities and distinguishing communities with varying thematic content in neighborhood graphs. An examination of the distribution of community sizes in a particular iteration of the algorithm reveals that for sufficiently large neighborhood graphs a power law is observed.

abstract:
Background: Community Long-Term Care Services (CLTCS) are intended to support
caregivers and delay institutionalization of care recipients. Evidence suggests CLTCS are
under-utilized in Newfoundland by caregivers of people with dementia. Objectives: To
explore the meaning of caregiving among caregivers in Newfoundland; to investigate a
range of factors that may influence CLTCS utilization; and to assess CLTCS capacity in
the region. Methods: Survey and interview of a sample of caregivers from the Canadian
Study on Health and Aging, and a historical survey of homecare agencies. Results:
Despite an apparent need for services, caregivers did not want CLTCS delivered in the
home by strangers. Caregivers were more accepting of out-of-home services. Too few
homecare agencies responded to the survey to carry out an analysis. Conclusions: The
meaning of caregiving for caregivers affects the acceptability and utilization of CLTCS.
Currently used quantitative instruments may benefit from supplementary qualitative data.

title: Reduced complexity turbo decoders

abstract: Turbo codes are a class of forward error correction codes, which have outperformed all the previously known error coding schemes. The strength of this scheme lies in the parallel concatenation of component codes and their iterative decoding algorithm. Although turbo codes have found their way in a number of future wireless communications standards, their efficient implementation in hardware and software is still being actively researched. This study therefore focuses on the design of efficient turbo decoders. The dissertation begins with the description of encoding and decoding of turbo codes. Sliding window implementations of decoding algorithms, which are used to reduce the memory requirements in turbo decoders, are presented. The contribution of this work is the proposed modifications to the conventional sliding window implementations of SOVA, bi-directional SOVA and Max-Log-MAP based turbo decoders. The proposed modifications allow multiple bits to be released in a single decoding window thus reducing the computational complexity and increasing the decoding speed of turbo decoders. A performance and complexity comparison of these decoder implementations is also presented.

title: The French Shore question, 1865-1878

abstract: From 1865 to 1878 the dispute over French rights in Newfoundland included the question of Newfoundland included the question of Newfoundland territorial control over the French Shore as well as the older controversy concerning exclusive and concurrent rights in the fishery. This newer aspect of the French Shore Question partially resulted from the intense competition between France and Newfoundland in the fishery. -- After 1815 the French had established a prosperous fishery off Newfoundland based on the Islands of St. Pierre and Miquelon and on the French Shore. This state-supported industry by creating strong competition for Newfoundland fishery products in world markets threatened the colony’s one-product economy. Newfoundland had retaliated at first by legislation aimed at restricting the French fishery. When this failed, an effort was made to provide alternative sources of employment of an expanding population by developing the other resources of the island. As the French Shore was considered a prime region for development, Newfoundlanders, since about 1850, had been trying to extend government and industry to this area. Between 1865 and 1878 this effort was characterized by the demand of the Newfoundland government for the right to appoint magistrates and grant land on the shore. The Imperial government, worried over possible French reaction, at first refused both these demands. Instead, hoping to satisfy the colonists while avoiding any dispute with France, they proposed in 1868 the resumption of the fishery negotiations which had been suspended in 1861. The French proved reluctant but eventually agreed in July, 1873. But the Miller-Boissoudy discussions which followed failed to produce any agreement. Together with the persistent agitation in Newfoundland this led the British in 1878 to make a concession in principle to the colony by appointing a magistrate on the French Shore. When F.B.T. Carter retired as Premier that year, the over optimistic impression in Newfoundland was that his negotiations with the Imperial government had solved the question of British territorial rights on the French Shore.

title: Prolate spheroidal digital filtering

abstract: The use of Digital Prolate Spheroidal Wave Functions (DPSWF) in the field of digital filtering has increased steadily during the past decade. The unique property: that DPSWF provide maximum concentration of signal energy in the passband of a low-pass filter has been the basis of most of the work done in the area of digital filter design involving the prolate functions. The maximization of energy corresponds to the largest eigenvalue, which belongs to the lowest order DPSWF, and the energy concentration decreases as the order increases. -- It is, however, desirable to investigate the effect of higher order eigenfunctions in addition to the lowest order one on the filter  characteristics and performance. This thesis is the outcome of such investigations. A suitably weighted linear combination of those DPSWF which are even functions of frequency is made to approximate an ideal low-pass characteristic in the minimum mean squared error (MMSE) sense. -- Results employing various numbers of even prolate functions are obtained and compared with each other and with the maximum energy concentration case. It is shown that the flatness of the passband of a low-pass filter is greatly improved with the number of even prolate functions while maintaining a tolerable loss of energy in the passband. -- One of the key features of the lowest order DPSWF, is that its side lobes are very low. This is a direct result of maximizing the concentration of energy within a certain interval. This feature is very useful for harmonic analysis problems. This is demonstrated by applying the prolate function as a window in harmonic analysis using discrete Fourier transform. The performance of the prolate function is compared to that of many other popular window functions, in the present work.

Masters thesis, Memorial University of Newfoundland.

abstract: Colorectal cancer is a significant health concern in the province of Newfoundland and Labrador (NL) which has the highest age-standardized incidence and mortality rates for colorectal cancer in Canada. Several studies have attempted to identify inherited genetic variants which can serve as independent prognostic markers in colorectal cancer patients. We have conducted such a study in two colorectal cancer patient cohorts (discovery and validation sets) from Newfoundland. We investigated 27 genetic polymorphisms in the discovery cohort and attempted to replicate the positive correlations in the validation cohort. Our results showed that the MTHFR _Glu429Ala polymorphism was associated with worse overall survival in two cohorts albeit with an apparently different pattern of inheritance. An association of the heterozygote genotype of this polymorphism with shorter overall survival was also detected in male patients from both cohorts. Another polymorphism, ERCC5_His46His, was also found to be associated with disease-free survival in these cohorts. Further studies on these polymorphisms may facilitate understanding of the mechanisms behind prognostic differences among colorectal cancer patients and aid in better prediction of clinical outcomes.

abstract: This thesis examines trends in consumer choice and availability resulting from the economic interaction between the Inuit of northern Labrador and their Euro-Canadian trading partners from the late eighteenth century to early twentieth century. This analysis aims to produce a better understanding of the progressive incorporation of European goods into Inuit society, as well as the reasons behind product choices. The final results of this work are concerned with the relationships between the Inuit, their material culture, and their trading partners. The sites demonstrate a successive transition to a culture more materially hybrid than traditional culture patterns. This included the transition from the use of Euro-Canadian material in traditional Inuit forms to the use of Euro-Canadian forms within Inuit culture. It also attempts to apply gender theory to an understanding of material choice within a larger study of Inuit consumerism during this period.

abstract: Owner's cost control of large scale construction projects within a Project Management environment requires the processing of large amounts of information relating to quantities and unit rates for work expended and work yet to be performed. Cost control is based upon monitoring reports summarizing and presenting the available data and the adoption of appropriate management responses. Due to the amount of information to be considered, computer processing is almost universally adopted, necessitating management decisions upon the most appropriate of a number of competing computerized cost control programs to be adopted by a particular owner's organization. Such decisions require a basis for comparison. Unbiased comparisons are the ideal to be attained, and to this end, this thesis develops a methodology utilizing a classification system devised to remove some of the elements of bias currently surrounding decisions regarding suitability of any particular proprietary computer program for any owner. -- The methodology consists of an owner initially determining his information reporting requirements in terms of the classification of data to be presented in each report. For any particular program, the information presented by every report is classified in a similar manner. By comparison of the owner's requirements and the particular program under review, determination may be made concerning the suitability of that particular program for the owner. A number of such available programs may be evaluated against the owner's requirements utilizing the methodology and, by simple discrimination, achievement of unbiased selection of the most suitable is rendered possible. -- The methodology has been computerized and an example of its use is included. Finally, suggestions for further work in this area are made.

abstract: All across the country, people are participating in community gardening activities as a way to learn and share gardening knowledge, gain access to fresh produce, develop social bonds and improve the physical features of neighbourhood and public space. In the eastern Canadian province of Newfoundland and Labrador, community gardening is becoming a popular way to access fresh produce and learn or practice gardening skills. While gardening has traditionally been practiced by families residing on the island of Newfoundland (Omohundro 1995), community gardens are a more recent facet of food production there. Little academic attention has been given to gardening in Newfoundland and Labrador since the mid-1990s. Fostered by what may be conceived of as a burgeoning food security movement, there is much hope amongst community garden organizers that these spaces will address food insecurity and personal health needs amongst the provincial population. -- This thesis examines the Rabbittown Community Garden, which is located in a social housing neighbourhood in St. John’s, Newfoundland. By considering the history of the garden’s development, as well as the interests, needs and perspectives of persons who helped to organize and maintain it, I seek to question the significance of identity to participation in community gardening. My research indicates that the benefits of community gardening are diverse, that identity and sense of place contribute to women’s and men’s tastes for particular vegetables, and that there are both opportunities and challenges presented to those who participate in community gardening at Rabbittown. This thesis provides a nuanced approach to understanding the range of activities that are involved in community gardening, and updates previous considerations of gardening in Newfoundland and Labrador.

Objective: To determine the incidence of type 1 diabetes mellitus among
children aged 0 -14 years in the Avalon Peninsula in the Canadian Province of
Newfoundland and Labrador. -- Research Design: Prospective cohort study. -- Participants/Setting: Children aged 0-14 years who were diagnosed with type 1
diabetes mellitus from 1987 to 2002, on the Avalon Peninsula of Newfoundland. -- Methods: The primary objective was to determine the incidence of childhood
type 1 diabetes mellitus (T1DM). Identified cases during this time period were
ascertained from several sources and verified using the capture-recapture
technique. Data were obtained from the only pediatric diabetes treatment center
for children living on the Avalon Peninsula. -- Results: Over the study period 294 children aged 0-14 years from the Avalon
Peninsula were diagnosed with T1DM. The incidence of T1DM in this
population over the period 1987 - 2002 inclusive was 35.93 per 100,000 per
year. The incidence over this period increased linearly at the rate of 1.25 per

abstract: This qualitative descriptive case study examined co-operative education coordinators' perceptions of legal and ethical risks in co-operative education programs in Canadian universities. Fourteen coordinators from across Canada participated in one-on-one interviews. Specifically coordinators were asked about their perceptions of their responsibilities and liabilities for the risks that students face in the workplace, the risks the students pose in the workplace, the risks to the employer, the risks to the institution, and the risks to the coordinators themselves. -- The coordinators who participated in this study identified numerous potential risks associated with co-operative education to each of the co-operative partners; however, the student was perceived as the partner who is the most at-risk. Coordinators in general were risk aware and conscious of their role in protecting students. Largely, the coordinators believed that cooperative education is a safe endeavour and examples of extreme situations were very rare. -- Coordinators' opinions varied quite considerably when asked about the extent of their responsibility in assessing and minimizing risk. Generally coordinators understood risk assessment and risk management to be part of their role and agreed that responsibility for minimizing risk should be shared between the coordinator, the employer, and the student, but the balance of who was more and who was less responsible varied considerably. Many coordinators expressed that they were not clear where the boundaries of their responsibilities lay and that they often used their own judgment to determine what they were and what they were not responsible for, rather than being guided by institutional policy. It is likely that the subjectivity in coordinators' perceptions of their responsibilities and variability in understandings of risk and liability result from unclear or poorly articulated formal policies and procedures in many cases. -- Coordinators stated that their universities had done nothing to prepare them to reduce potential risks in co-operative education and that largely their abilities to do so were learned from colleagues or resulted from common sense and previous work experiences. Coordinators rely, in large part, on their own tacit knowledge to reduce risk rather than relying on expert advice from risk managers. Seemingly, university administrators and risk managers are doing little, if anything to participate in risk communication with the great majority of this population of coordinators. Despite the lack of preparation offered by universities, coordinators largely felt supported by the policies of their institution, although there was a strong sense that coordinators sought clarity or more information on policies related to risk.

abstract: Laser scanning confocal microscopy was used to image a thin sediment of a Brownian colloidal suspension of PMMA spheres in a decalin/TCE solvent. The sediment is imaged in its entirety in 3-dimensions, as well as with 2-dimensional time-series captured incrementally throughout the sediment. The structure and dynamics are analysed and compared to a hard-sphere system. AC electric fields are applied parallel to gravity to attempt to induce a dipolar interaction in the colloidal spheres. If the system is confirmed to be hard-sphere like, then this allows comparison of the system with applied fields to a hard-sphere-plus-dipolar system.

abstract: The Harris-Nesbet variational method is used to carry out accurate calculations for electron collisions with hydrogen atoms at low energy below the first hydrogenic excitation threshold. Calculations are done with the employment of different coupling schemes which are composed of the atomic hydrogen states and pseudo states and a great number of correlation terms. Singlet and triplet phase shifts are obtained for the partial waves L=0, 1, 2, 3, 4, 5, 6 and 7. Phase shifts at the nine energies, where experimental data of differential cross section are available, are obtained with the partial waves L equal to up to 18, and then used to deduce the elastic differential and total cross sections for electron collisions with hydrogen atoms at these energies. The results of the present Harris-Nesbet calculations are compared with those made available in literature by other research groups. The differential cross sections obtained are compared with experimental data, and an excellent agreement is found between the two.

abstract: Cocoa plays a dominant role in the economy of Ghana and as a result is usually referred to as the backbone of the economy. It accounts for over two-thirds of the country’s exports and is the most important source of her foreign exchange. With a population of seven million, Ghana is the world’s largest single cocoa producer supplying about one-third of total world output. The crop contributes a bulk of the value of her agricultural exports and the economic prosperity of the whole nation is directly geared to the level of cocoa prices. -- Ghana provides an example of an underdeveloped country which is exclusively dependent on one primary export commodity. Although she has made tremendous economic progress (relative to other countries in West Africa) since independence in 1957, like all less developed countries she is still clamouring for more. But the post-war period has brought large increases in cocoa production not only in Ghana but in other producing countries as well. In spite of the fact that world consumption has increased, stocks have accumulated and the current price level is low. -- The main objectives of this research are: (1) to analyse the overall impact of cocoa in Ghana from 1900 to 1963; (2) to test the applicability of certain hypotheses such as that there is very little relationship between cocoa production in Ghana and the prices received by producers; that cocoa exports are closely related to production; that prices in the world market affect the demand for cocoa; (3) to analyse the problems that this single-commodity economy has to contend with and (4) to suggest methods by which these problems could be overcome. -- Chapter I is rather unique in the thesis. It deals with some of the theoretical views that have been expressed since the classical economists on the relationship between export trade and economic development. The purpose of that chapter is to lay a foundation for the practical analysis in the succeeding chapters of cocoa - an agricultural export commodity - on the economic development of a country. Chapter II deals with the historical analysis from 1900 to 1963. The next chapter is the core of the whole text; various contributions of cocoa - loans, grants, education, investment, employment, government revenue - are sketched. Chapter IV deals with the problems from the international and national aspects. Finally, Chapter V attempts to solve these problems from three angles - the international, regional and national levels. -- The writer has drawn from the works of others but most of the analyses are original. Data was mainly obtained from United Nations publications, Reports and other publications of the Ghana Cocoa Marketing Board, Cocoa Statistics by Bill and Dufus Limited of London, Africa Digest and Statistical Reports from the United States Foreign Agricultural Service. But being so far away from Ghana, the extent to which information could be obtained from the government concerned has been small. This has strongly inhibited the use of more statistical tables and figures especially in Chapter III. However, this setback was partially overcome by concentrating on those years for which data is available.

abstract: The purpose of this study was to explore how social presence manifests itself in the web-based synchronous secondary classroom (WBSSC) and to gain insight into the perspectives of teachers on their role in fostering social presence. Data were gathered using semi-structured and structured observations of recorded web-based synchronous classes, and semi-structured interviews of the teachers who work in synchronous secondary [high-school] classrooms in the province of Newfoundland and Labrador, Canada. Findings revealed that social presence was manifested through affective, expanded affective, cohesive, interactive and audio-sensory categories of a revised instrument for identifying social presence. Social presence manifested itself for students through the use of text-based Direct Messaging and for teachers through use of two-way audio. Students relied on the conventions of communication of informal synchronous chat to manifest social presence. Teachers perceived their role to be models of behaviors that foster social presence, to be willing to use self-disclosure, to help students build communication skills, help foster a sense of group cohesion, to foster a real and engaging classroom experience, and to help students to create an identity. Implications for practice include the need for online teachers to make conscious choices regarding which tools will be used by students and for what purposes.

abstract: This study was undertaken to show that a remote fishing lodge in Labrador holds many elements of occupational folklife. The practice of actual angling was not looked at, but rather the guides' canon of work technique, joking behavior, foodways, pranks, and narratives were explored. This thesis shows that the job of a guide extends beyond angling to include the role of entertainer and tourism operator. The guides are easygoing people who love fun, but they also establish and maintain boundaries that guests must respect. The guides' position in the lodge's hierarchy is reflected in the lodge's division of space as well as in the guides' interactions with guests, as seen in their efforts to influence an anticipated tip. People come to the lodge to enjoy some of the world's best fishing but it is through the lodge's occupational folklife that a sense of community is created and nostalgic memories and lasting friendships formed.

abstract: Many physical systems in general, and soil materials in particular, exhibit relatively large spatial variability in their properties, even within so-called homogeneous layers. Physical descriptions of this spatial variability are not feasible owing to the prohibitive cost of sampling and uncertainty induced by measurement errors. This variability is widely dealt with as uncertainty in soil properties. Probabilistic methods currently used to represent this uncertainty often suffer from many limitations. For instance, they often only account for uncertainty in estimating the average soil properties. A probabilistic approach was developed here to investigate the effects of soil heterogeneity and provide practical recommendations and guidelines to account for these effects in routine engineering design. -- There are still many unknown consequences of spatial variability. It is shown here that natural variability of soil properties within geologically distinct and so-called uniform layers affects soil behaviour. This study found that the phenomena governed by highly nonlinear constitutive relations are the most affected by spatial variability of soil properties. The bearing capacity of shallow foundations and lateral interaction loads of buried pipelines are functions of soil shear strength and, therefore, are governed by highly nonlinear stress-strain relationships. -- The effects of soil heterogeneity were investigated for a strip foundation placed on elastic perfectly plastic soil and subjected to vertical loads. From a comparison of Monte Carlo simulations, accounting for the spatial variability of soil strength, and deterministic analyses assuming uniform soil properties, it was found that the soil heterogeneity changes the mechanical behaviour of foundations. A parametric study was performed to quantify the effects of soil heterogeneity parameters on foundation response; the studied cases were pre-designed using statistical methods (Design of Experiments, DOE). It was observed that soil strength's degree of variation and probability distribution, which characterize the amount of weak pockets of soil, have the most effects on the foundation behaviour for the range of parameters considered. Correlation distances also affected the variability of foundation responses owing to local averaging effects. -- The results of the parametric study are presented as simple regression equations (response surfaces) to estimate probabilistic characteristics of foundation responses - namely mean and coefficient of variation of bearing capacity and bearing pressures at damage criteria. They were used to calibrate partial design factors for limit state design methods, LSD, and estimate characteristic values for routine engineering design. The results, in terms of regression equations, can also be employed directly in level II & III reliability analysis methods. -- A similar study with a limited scope was performed for lateral loading of a buried pipeline. Only one burial depth (geometrical configuration) was taken for the pipeline. Among the probabilistic characteristics of soil considered here, the degree of variability of soil strength was found to be the most significant factor affecting pipeline response. The response and failure mechanism of a laterally loaded buried pipeline is complicated and is dependent on several deterministic factors such as burial depth, pipe-soil interaction coefficients, and soil weight. The study could be further developed to account for other probabilistic characteristics and deterministic parameters, and their corresponding interactions.

abstract: In the 20th century, a process of language shift took place among French Newfoundlanders living in Cape St. George, Newfoundland. This involved a consolidation of English and French being inscribed with diglossic values — with English as the high variety and French the low. A French revitalization movement was formed at the Cape in the early 1970s with the goal of reversing the effects of language shift. It took the form of resistance of reversal, adopting the oppositional logic of diglossia but inverting the relative power of each language. Language activists with the French movement have been guided by the oppositional one language/ one people ideology, an ideology which equates group identity with a single language and tends to favour linguistic purism. The influence of this language ideology is most clear in the acquisition and evolution of French education at the Cape, a process which, ironically, introduced a second language hierarchy into the community. -- Language shift and language revitalization have transformed Cape St. George into a linguistically heterogeneous speech community, where varieties of English and French are spoken with varying degrees of competence and willingness by residents there. I argue that unmarked codeswitching between French and English, regardless of a person's French language ability is the quintessential language pattern of French Newfoundlanders. -- Criticisms of the French movement are generally criticisms of the exclusionary practices and policies engendered by the oppositional one language / one people ideology. People object to these polices and practices because they do not match their experience of their community or their more plurilingual definition of French Newfoundland identity. This popular rejection of the French movement may be considered a form of radical resistance.

abstract:
Balsam fir relies on disturbance events to create canopy gaps into which advance
regeneration can grow. To determine the factors responsible for the failure of balsam fir
forest regeneration in Eastern Newfoundland, various components of the early
reproductive processes were compared among various combinations of management and
disturbance regimes (Protected-intact canopy; Protected-open canopy; Cut block-domestic;
and Cut block-commercial). Pollen availability and viability, seed production
and quality, seedling emergence and survivorship were examined within each
management/disturbance regime. The results indicate that reproduction of balsam fir in
this ecoregion is not limited by the availability or quality of pollen, but in part by reduced
numbers of female cone producing trees within insect disturbed and selectively cut
stands. Protected intact canopy and domestic cutting blocks contained the highest
proportions of optimal seedbed, the lowest levels of herbivory, and therefore the highest
densities of juveniles. Disturbance regime is directly linked with the early reproductive
processes of balsam fir. Therefore, to implement sustainable forest management, natural
disturbance patterns must be more closely mimicked to ensure survival of early life
history stages.

Masters thesis, Memorial University of Newfoundland.

abstract: It is well documented that preschoolers' narrative ability is a precursor for literacy. In fact, narrative ability at age four has been shown to predict reading comprehension as far into the future as the seventh grade. Because this oral language skill sets the foundation for literacy, it is important to identify factors which promote its development, particularly among high-risk groups. The present research explored two potential factors among 56 economically disadvantaged mother-child dyads: parenting stress and attachment security. Surprisingly, a significant relationship was not found between either parenting stress or attachment security and different properties of children's narrative ability. In fact, these variables only accounted for a very small proportion of the variance of all of the narrative properties analyzed. Restricted range in narrative ability and attachment security among the present sample may account for the non-significant findings. Future research aims to investigate whether subsequent intervention by fostering more proactive interaction skills will improve children's narrative ability and/or affect parenting stress among mothers.

abstract: The primary purpose of this study was to determine whether socioeconomic variables were more highly related to arithmetic achievement among grade VI pupils of rural Newfoundland than were certain educational input variables. In addition, the relationships between arithmetic achievement and sex, intelligence, reading ability, mother's education, father's occupation, size of family, absenteeism, classroom enrolment, teachers' qualifications, and the age of the school building were investigated. -- Data were collected, during the month of May, 1968, by means of two questionnaires and three standardized tests, from 77 teachers, 684 parents and 684 students; all resident in the two Electoral Districts of Trinity North and Trinity South. -- Descriptive and statistical analyses were made of the data thus collected. The statistical procedures used to test the hypotheses included "t" tests, Pearson product-moment correlations, partial Pearson product-moment correlations and multiple correlations. -- The major finding of this study revealed that the combined socioeconomic variables were more closely associated with and thus explained more of the variance on arithmetic achievement than did the combined educational variables. Girls were found to score significantly higher than boys on arithmetic problem solving but no significant difference was found between the scores of these two groups on arithmetic concepts. Intelligence, reading ability, mother's education and father's occupation were all found to be significantly related to pupils' scores on both measures of arithmetic achievement. Size or family was found to be more closely associated with the arithmetic achievement of girls than of boys. No significant relationships were found between arithmetic achievement and absenteeism. With the exception of girls on arithmetic concepts, no significant relationships were found between teachers' qualifications and arithmetic achievement. Neither the classroom enrolment nor the age of the school building showed any significant relationships with arithmetic achievement. Intelligence and reading ability were found to be the most important variables associated with the arithmetic achievement of students used in the study. -- The major finding suggest the need for educators to consider, when devising or implementing any arithmetic program, the socioeconomic background of the student population to be served. Compensatory education should be provided for students who come from the lower socioeconomic strata of society, and the present provincial government's policy of providing adult continuation classes should be extended to all areas of the province. -- Since the level of arithmetic achievement was found to depend to an important degree on the students ability to read, any improvement in this aspect of the curriculum should bring a corresponding improvement in the level of arithmetic achievement.

Masters thesis, Memorial University of Newfoundland.

abstract: In recent years, there has been a variety of research which has addressed the factors affecting the measurement of error bounds when using high frequency (HF) radar for ocean parameter measurements. The study presented here is conducted in order to identify other important factors that should also be considered in establishing meaningful error bounds on any ocean parameter extracted from the received radar signal. Specifically, this research aims at investigating the fluctuations in the Bragg peaks of the HF radar received spectra based on recent cross section models. -- The first part of the research work reviews the electric field equations for the backscattered signals when pulsed and frequency modulated continuous wave (FMCW) waveforms are used as transmitting waveforms. The incident radar signal is assumed to be scattered from the ocean surface, which is represented as a zero-mean Gaussian random process. Various operating parameters are selected to simulate the time series electric field for different conditions, and the power spectral densities (PSD) are calculated by the periodogram method. Again, an investigation is carried out to examine the signal to noise relationship in the Doppler spectra when a pulsed radar system has a noise limited reception. The noise is assumed to be external with no attempt to address internal noise features. It is assumed that the noise is an additive white Gaussian process. To develop the noise contaminated signal, a suitable noise model is incorporated in the time domain of the electric field signal. The Doppler spectra are calculated and examined for various signal to noise ratios. -- The second part of the research work examines the fluctuations in the Bragg peaks of the received Doppler spectra from the ocean surface. An investigation is first carried out for an ideal noiseless radar system. Choosing various operating frequencies, pulse widths (pulse waveform) and frequency bandwidths (FMCW waveform) for the simulations, numerical examinations of the existence of spectral fluctuations and Bragg distributions are conducted. The centroid positions of the Bragg peaks are calculated and compared with theoretical values to reveal the relative difference. To check the significance of the fluctuations, the standard deviations of the centroid positions of the Bragg regions are analyzed and compared to the resolution imposed by the fast Fourier transform (FFT). The results show that the standard deviations vary for various operating parameters of the radar. -- Finally, using the noise model introduced in the first part of the analysis, the investigation of the Bragg fluctuations is extended to a noise limited pulsed radar waveform. The standard deviations of the centroid positions are observed for different signal-to-noise ratios, operating frequencies and pulse widths. The significance of the noise level in the Bragg fluctuations is considered at the end of the analysis.

abstract: The purpose of this study was to investigate and explore to what degree the Preschool Early Intervention Program at St. Mark’s Elementary School in Shearstown, Newfoundland, has been a success. Of specific interest was the Preschool Early Intervention Program’s effectiveness and range of changes that have occurred in the seven year duration of the program. Comparison was made between children who had attended the Preschool Early Intervention Program at St. Mark’s and their older siblings who had not attended the program to investigate its effectiveness. – The investigation of the program included interviews with three groups in half hour sessions using open ended questions. Twenty parents, seven teachers, including the volunteer instructor of the program, the two present administrators and the former principal were chosen because they had a child that had participated in the program and at least one older child that did not. The administrators and the teaching staff had taught children in classes that had been participants and also nonparticipants of the program.  Questions during the interviews focused on perceived educational achievement, reading and study habits, and quality of school life. The impact of parental involvement and other unpredicted benefits were also noted. Results are described relative to the framework of the perceptions of those involved in the Preschool Early Intervention Program at St. Mark’s Elementary School within the social context of its community. Overwhelmingly, the program was deemed effective. Effectiveness was determined by the consensus and verification of the perceptions of the parents, teaching staff, and the administrative staff of the school as given to this researcher throughout the interviews. – A comparative look at standardized tests, teacher made tests, and teacher written observations served as data to confirm the degree of success.  Standardized testing has been periodically documented for the school population. The school profile containing the documentation was available for the study. Analysis of the data indicated that the program had affected growth in educational achievement. These findings are based on the comparison of grade level scores between the participants and nonparticipants of the preschool program. In all preschool graduate classes the achievement levels are significantly higher when compared to the nonparticipating classes. – IN particular, the interpretation of the parental interviews played an integral part in the study. The preschool program has focused on the prekindergarten experience of the four year olds from this community. These children have attended the sessions with a caregiver. These caregivers, often parents, were coached in instructional strategies through modelling. They purchased literature and were given additional materials for home instruction. The role of parents was vital to the program and their perceptions of its effectiveness were valued. – The interviews revealed a major observable change that had affected the organizational nature of St. Mark’s. The active involvement of parents in the education of their children at home and at school was quoted by parents and teachers as the greatest change in the relationship of the parents to the school during the education of their own children. Today, parents are visible in their supportive role throughout the whole school building. The early involvement made the parents more aware of the role they could play in ensuring home study and attention to the importance of school work by their children. – Based on information obtained in the review of related literature, test score comparisons and from the opinions of the parents and teaching staff at St. Mark’s, an effective preschool early intervention program has been described in this thesis.

abstract: It is known that "human error" is the primary cause of the majority of incidents occurring in process activities. Such incidents can lead to unacceptable outcomes. Each year, there are billions of dollars lost and many injuries/deaths occurring as a result of human error which could have been avoided. Human factors play an important role in causation of these human errors leading to losses. Human factor is the information about human characteristics and behavior controlling human performance. Human errors are inevitable due to the noticeable role of human in operation, maintenance, analysis, decision making, and expert judgments, particularly in complex systems. To reduce the human error, the methods of Human Error Probabilities (HEPs) have been identified. Each technique has its own advantages and disadvantages and may need to be tailored for use within a specific scenario. The focus of this research is to develop comprehensive methodologies to estimate the HEPs in pre and post-maintenance procedures of process facilities. It also develops a risk-based methodology to investigate the reliability of human performance in harsh and cold environments. The methods "Success Likelihood Index Method (SLIM) and Human Error Assessment and Reduction Technique (HEART) HEART" have been used for this purpose. Using HEART methodology, the HEP in different scenarios in an offshore platform is estimated. Also, the high-risk activities in pre and post maintenance of process equipment are identified and the HEPs are reduced through a risk-based decision- making methodology. -- SLI methodology is used to calculate the HEP of the procedures for removing process components from service and returning the equipment to service as a possible failure scenario. Consequences and the individual risks are assessed for each component, and then the overall risk is estimated by adding these individual risks. Also, the HEP is assessed by integrating the SLIM with the Technique for Human Error Rate Prediction (THERP) to generate the nominal HEP data when sufficient information is not available.

Masters thesis, Memorial University of Newfoundland.

abstract: This project report provides a description of a learning resource teacher’s experiences in developing a staff training project that was more than just a one-shot deal. It describes professional development practices for implementing technology integration at one rural central high school in Newfoundland. Concurrent with the literature review, an action-research project was designed to encourage ownership, input, and collaboration among the staff. The project was designed to assess the needs of the teachers and to give them a voice that could influence their training. -- A focus of this project was to create an awareness of technology and to provide ongoing support to meet teachers’ needs for using and integrating technology into their programs. The structure of this project allowed the researcher to study the stakeholders involved in technology initiatives at this school. By immersing himself into his study as a participant-observer, the research was able to develop survey instruments that measured the staff’s needs and feelings about technology. Information collected through these instruments was used to enhance the design of the teachers’ Technotraining initiatives. – Chapter One gives a brief introduction of the study including the problem, the goals and objectives, and the components of the project; outlines the organization of the report, and explains its writing style. Chapter Two describes the methodological framework used in the project: identifies the action research process, recognizes the literature review that was concurrent with this process, describes the use of the district’s framework for implementation, identifies the research as an active participant-observer, and provides a profile of the intended users of the initiatives. It describes the purpose and design of instruments constructed and used. Chapter Three contains the review of literature related to research regarding professional development, change theory, and technology and its implementation, as it relates to schools. It concludes with relevant guidelines that grow out of the literature. Chapter Four includes a reflective journal detailing the school self-study through the use of the action-research model. It gives a chronological account of the project’s design and implementation through the researcher’s observations and reflections. Chapter Five lists guiding principles that were drawn out of the research and describes lessons learned from their practice. Chapter Six describes the rationale and a copy of the teachers’ materials that were developed for this training process. References to other documents from the literature that could be used to enrich the training process are also provided. Chapter Seven presents the results of the project. This includes recommendations, staff reactions and feedback, and revisions and additions to the project, the possibilities for further work, and its transferability to other schools. It ends with a discussion of professional development planning as a learning experience.

abstract: The role of leadership in schools has always elicited much debate in academia. For the past two decades, critics and scholars have placed much emphasis on the emerging theory of transformational leadership as an appropriate model for school leaders. The roots of this theory are examined in this folio as well as modifications that have been proposed by scholars in the leadership field. The principles and practices inherent in the concept of transformational leadership are described and the implications for school leaders are synthesized. -- Another issue at the center of debate in education is the emerging role of information technology in schools today. Some of the current realities of integration efforts are described in this folio. Incidents of use, misuse and non-use have been documented and are summarized. Then the potential for these new technologies to impact upon education is explored. The aim is to demonstrate the importance of continuing with integration efforts because of the potential positive impact it can have upon teaching, learning and reforming in education today. -- Finally, the factors that impact upon the integration of information technology in schools are explored. Among these factors, the role of leadership has emerged as one that has a large impact upon the success of integration efforts. Thus the role of leadership in integrating information technology to create information age schools is the focus of the last paper in this folio.

abstract: This qualitative-descriptive study reports data regarding the nature of mother-daughter relationships in seven incestuous families. The sample of seven girls (n=7) had all been confirmed victims of father-daughter incest. The sample were all involved in eight group psychotherapy sessions prior to exploration of the mother-daughter relationships. All of the sample were interviewed individually at the Department of Social Services, St. John’s, Newfoundland during November to December, 1981. The interview consisted of a questionnaire addressing four specific areas of the mother-daughter relationships: 1) affection between mother and daughter, 2) communication between mother and daughter, 3) conflict between mother and daughter and 4) mother’s reaction to incest disclosure. The questionnaire was a non-standardized measure with both open-ended and closed questions. – Analyses indicated that all seven girls were of adolescent age and most had been involved in lengthy and frequent sexual contact with their fathers. All of the families were dysfunctional and socially disruptive factors such as alcoholism, violence and promiscuity were frequent occurrences. Following incest disclosure four of the daughters were placed in foster homes while four of the parental couples remained living together. – Examination of the mother-daughter dyads revealed that there was general dissatisfaction among the daughters in their interactions with their mothers in the areas of communication, conflict and mother’s reaction to incest disclosure. – The study findings may have relevance to clinical intervention and treatment. The study indicated that more investigations of incestuous families are necessary in order to assess the nature of the mother-daughter relationship.

abstract: In this dissertation, two treatments, intraischemic hypothermia and glutamate receptor blockade, were evaluated for neuroprotective efficacy against global ischemia. Since the standard assessment of ischemic damage using only histological outcome reveals nothing about function, I used multiple outcome measures including behaviour and electrophysiology, as well as a histological evaluation. In order to further increase the strength of this approach, multiple assessments were made in the same animals. -- Intraischemic hypothermia induced by selectively cooling the brain conveyed both long-lasting protection against functional loss as well as cell loss. These findings provide a strong argument for the implementation of hypothermia in cases where the occurrence of an ischemic episode can be predicted before it occurs (e.g. elective cardiac/neuro-surgery). However, most cases of ischemia, or stroke, occur without warning thereby precluding the use of intraischemic hypothermia. -- NBQX, a glutamate receptor antagonist which selectively blocks the AMP A receptor, is reportedly neuroprotective when treatment is delayed several hours postischemia. The same approach developed to evaluate intraischemic hypothermia was ·used to study NBQX. In the course of these studies it was found that NBQX induced a mild, prolonged, hypothermic action. Due to the ability of hypothermia to mitigate ischemic damage and the confounding effects of hypothermia in previous pharmacological studies of ischemia, it became important to determine whether the hypothermia induced by NBQX contributed to its mechanism of action. The results strongly suggest that NBQX conveys neuroprotection through a hypothermic action. These data raise important questions concerning current hypotheses of ischemic cell death, which currently focus primarily on involvement of the AMP A subtype of glutamate receptor. -- Finally, the behavioural changes that follow an ischemic episode were characterized with reference to variation in ischemic severity. Two types of behavioural alterations were noted: (1) an acute increase in activity following ischemia, and (2) a chronic increase in locomotor activity triggered by novel environments after the acute phase recovers. This second phase of increased locomotor activity was previously thought to reflect an impairment in spatial memory. Instead, it may be due to a form of behavioural sensitization not unlike that induced by stimulant drugs such as amphetamine.

An 8-week recreational swimming program was implemented to determine such benefits. The recreational program integrated physical activity and social interaction for participant development. Observations, questionnaires, and interviews were conducted to determine changes in physical and social behavior and self-esteem. A pre-post evaluation involving two children and four adolescents with cerebral palsy and spina bifida showed a significant improvement in their self-esteem. Observational data showed improved physical activity and social interaction and interviews supported these findings. During interviews respondents discussed perceived changes that occurred in physical and social domains and resulting growth and development including increased confidence, independence, and altered self-perceptions. Such findings indicate the importance of physical activity programs to the physical, social and psychological development of children and adolescents with physical disabilities.

abstract: This thesis presents a confrontation between two ways of conceiving self-other relations and community. For Edmund Husserl, the unity of the self has a primary and categorically privileged position in the constitution of the community of persons. His epistemological concern with certainty seems to make this prioritization of unity necessary. For Gilles Deleuze, the self does not have a categorically privileged position. The unity of the self is not conceived as primary and irreducible, but as constituted out of difference, or differential components. Because unity is not prior, others are conceived as playing a primary and fundamental role in the constitution of the self. A Deleuzian conception of community is therefore based on the reciprocal relations between selves, and not grounded on the constituting activity of the transcendental ego. I argue that the Deleuzian account is more faithful to experience in recognizing an essential passivity in the way selves are constituted and interact to form a community.

Masters thesis, Memorial University of Newfoundland.

abstract: This study examined the relationship between students' self-concepts of academic ability and achievement. More specifically, it investigated the differences in academic self-concept in students with similar levels of intelligence but with different levels of achievement. The study was designed to determine whether or not self-concept of ability was a significant factor in the achievement of junior high school students, and whether or not self-concept of ability functioned independently of measured intelligence in predicting school achievement. It attempted to identify the "significant others" related to school achievement, and it investigated the relationship between a student's academic self-concept and his educational expectations. The relationship between self-concept of ability and best and least liked subjects was also explored. -- The sample used in the study consisted of 193 students of whom 97 were boys and 96 were girls. This number represented almost the total enrollment of Grade VIII pupils in Ferryland District which is a rural area on Newfoundland's southeast coast. -- Data were collected during May and June, 1971, by means of a questionnaire, a standardized intelligence test, self-concept scales, and school records. -- Descriptive and statistical analyses were made of the data collected. The statistical procedures used to test the hypotheses included the t test and Pearson product moment correlation. Partial Pearson product moment correlations were also used. -- The major findings of the study revealed that self-concept of ability was significantly related to achievement when measured intelligence is controlled. Significant differences in the mean self-concept of ability scores of over- and under-achievers were found at all intelligence levels. Differences in the self-concept scores of boys and girls were significant only at low intelligence levels. -- Parents were named by more than 99 percent of students as concerned with their school work, while teachers were mentioned by 78 percent. The mean self-concept of ability score of students who expected to attend college was significantly higher than the mean score of those who expected to complete high school. The mean self-concept of ability score was significantly higher in whatever subject the student liked best than it was in the one the student liked least. -- These findings suggest the need for parents, teachers, and school counsellors to become more aware of the fact that a student's academic self-concept is closely related to his academic achievement. His performance depends not only on how intelligent the student actually is, but also on how intelligent he thinks he is. Counsellors and teachers, when devising or implementing new programs, should take the developmental approach to education. They should concern themselves with the prevention of negative self-concepts of ability in the formative years of students through early recognition and remediation of academic deficits. A measure of success should be afforded each student, for in terms of his future education and potential a sense of confidence and assurance is an important asset. With it the child can achieve much. Without it he will be handicapped despite the presence of even above average academic ability.

abstract: This dissertation explores representative postmodern novels by Kathy Acker (My Mother: Demonology), William Gaddis (A Frolic of His Own), and Robert Coover (John's Wife) for their highly political portraits of family in contemporary America. With a theoretical grounding in the ideas of Ernesto Laclau and Chantal Mouffe, this study seeks to address the ongoing debate between individual agency and family commitment in the work of three artists often accused of amorality in their writing. In contrast, I offer readings of the novels sympathetic to the ethical potential they offer for contemporary readers. It is my thesis that Acker, Gaddis, and Coover, rather than concentrate on the extremes of either liberal or communitarian theories, are aware of the presence of tenuous boundaries separating the two, leading to a more political interpretation of identity based loosely on citizenship as an articulatory principle for social commitment. Moreover, the postmodern offerings of Acker, Gaddis, and Coover, suggest alternative ways of exploring the family crisis issue. More than simply aesthetic portraits, each writer employs uncertain ontological and epistemological patterns in order to offer alternative moral possibilities for individual agency and family commitment. All three writers, in one way or another, interrogate rationalist notions of identity (both individual and collective) allowing readers to see the problems inherent in traditional theories of agency and commitment.

abstract:
Atlantic cod (Gadus morhua) show great potential for mass-rearing, but
much is unknown about their digestive capacity and efficiency. This thesis
provides an integrated study of survival, growth, behaviour, and digestive
enzyme activity in cod larvae and the variability in digestive development in
response to nutritional quality of live food enrichments. -- Experiments were performed investigating the effect of enrichments with
live food. The first experiment used high- and low-lipid rotifers (Brachionus
plicatilis) from hatching to 450 dd. Lipid level significantly impacted survival,
behaviour and digestive enzyme activity by 100-150 dd. A second experiment
examining Artemia franciscana enrichments from 450-650 dd resulted in larvae
fed a rotation diet showed the greatest survival and growth rates, but behaviour
was not impacted by enrichment type. High-protein and high-lipid diets were able
to induce significantly high post-prandial digestive enzyme activities. Results
indicate that diet plays a role in growth and survival, but also in the enzymatic
activity of the young fish's developing digestive system.

abstract: The objectives of the current research were (1) to determine the contribution of Mendilian inherited disease to the burden of disease caused by Endstage renal disease; (2) to explore the possibility that polygenic disorders could contribute to the development of Endstage renal disease; and (3) to describe the natural history of single-gene disorders associated with Endstage renal disease identified in the Newfoundland population, with particular focus on new data associated with Bardet-Biedl Syndrome. – To determine the risk of renal failure in family members of probands with Endstage Renal Disease (ESRD), all patients who were receiving treatment for ESRD during 1987-1998 in the province of Newfoundland and Labrador, Canada were studied. Detailed family histories were taken from 584 (87%) of the 669 eligible probands. Of the 85 patients with incomplete family histories, 60 (9%) could not be located and 25 (3.6%) refused to participate. The rate of renal failure in relatives of probands was compared to the rate of renal failure in spousal control families. Spousal controls were chosen because they have been shown to be less subject to recall bias and generally are similar to their spouses for environmental influences. Family histories were collected on 499 (85.4%) of the eligible spouses of probands. No spouses or next of kin could be identified for 65 (I 1%) of the probands and 20 (3.4%) of potential controls refused to participate. -- To determine the original cause of renal disease in the probands the medical records were reviewed. The information gathered was reviewed by a single clinical nephrologist who was blinded to the identity of the patient. Diseases with a Mendelian pattern of inheritance accounted for ESRD in 8.4% of the cases, 4.5% being autosomal dominant polycystic kidney disease, 2.5% Alport's syndrome and the remaining 1.4% to other genetic diseases. This group of cases was excluded from the subsequent familial risk analysis. Glomerulonephritis was the renal diagnosis in 25% of the probands, diabetes mellitus in 20%, unknown in 14%, other in 12%, interstitial in 11%, hypertensive sclerosis in 5% and multiple causes in 4%. -- Primary outcomes were defined as a positive family history of renal failure associated with renal replacement therapy in a first, second or third degree relative of a proband or control. In the group without a Mendelian pattern of inheritance, 28% had a first, second or third degree relative with renal failure associated with death or requiring dialysis versus 15% of controls. 1.2% of first degree relatives of probands developed renal failure compared to 0.4% of first degree relatives of controls (OR=3.0. 95% CI: 1.7-5.2). No difference was observed in risk for second degree relatives, but a highly significant increased risk was observed for third degree relatives of probands (OR=2.1. 95% CI: 1.2-3.4). The highest rate of affected first degree relatives occurred in relatives of probands with hypertensive nephrosclerosis (2.3%), diabetes mellitus (1.6%) and interstitial disease (1.6%). -- The second control group utilized was the provincial population. The proportion or relatives of probands registered with the Canadian Organ Replacement Registry (CORR) was compared to the rate of the general population. The provincial incidence of ESRD, registered with CORR, from 1981-1993was 79/million, excluding 8% or patients with Mendelian inherited disease. The comparable rate of ESRD in first degree relatives of probands without Mendelian inherited renal disease was 297/million almost four times the provincial rate. The comparable rate for first degree relatives of controls was 135/million. – Conclusions:  We conclude that not only is the contribution of Mendelian inherited disease to ESRD high, but there is also an increased risk or renal Failure in first degree relatives of probands without Mendelian inherited renal disease in a Caucasian population.

Masters thesis, Memorial University of Newfoundland.

abstract: Quality Daily Physical Education (QDPE) is a school program introduced in Canada in 1987. The purpose of this study was to examine the attitude of specialist and non-specialist teachers of physical education toward QDPE in Newfoundland and Labrador between May-October 1994. It was designed to determine whether there was any difference between the attitude of specialist and non-specialist teachers of physical education and to compare the findings between male and female teachers at various school categories and regions. -- The sample for the study was proportionally stratified from among the population of teachers of physical education in Newfoundland and Labrador. The basis used for this were mainly five regions, 33 different school boards and three school categories (i.e. primary / elementary, junior high school and senior high school). The number sampled was 56 physical education specialist and 37 non-specialist teachers of physical education. Responses to an attitude statement were scored on a 5 point modified Likert scale. The scores were coded and computed into SPSS-X program for analysis. Inferential statistics and one way analysis of variance (ANOVA) were used to analyze the data. -- The research findings indicated that there were no significant differences between the attitudes of specialist and non-specialist teachers of physical education toward QDPE in Newfoundland and Labrador at alpha .05 level of significance. Comparative study of the attitude of male specialist and female specialist teachers of physical education toward QDPE in Newfoundland and Labrador did not indicate any significant difference (alpha .05). -- Although no statistical difference was found, female specialist teachers of physical education appeared to be more positive toward QDPE than male specialist teachers of physical education. There were significant differences: (i) among specialist and non-specialist teachers on statements related to "teachers in general" at regional levels and school categories, (ii) among specialist and non-specialist teachers on statements related to school administration at school categories and regional levels, (iii) male and female teachers on statements related to facilities and (iv) among specialist and non-specialist teachers on statements related to school boards at regional levels. However, the overall results indicated that teachers of physical education in Newfoundland and Labrador are undecided about the implementation of QDPE in Newfoundland and Labrador.

Masters thesis, Memorial University of Newfoundland.

abstract: It would appear from the relative activities of key glycolytic enzymes, that succinate is the main end product of glycolysis in both the mantle and the adductor muscle of the giant scallop. The pathway of succinate formation appears to be similar to that postulated for other invertebrates. All the enzymes but one catalyzing the formation of succinate in the mantle and the adductor muscle were found in the cytosol. The enzyme catalyzing the reduction of fumarate was found in the mitochondrial fraction. -- The enzymes of the Bucher Shuttle were found in the adductor muscle. Thus two mechanisms are readily available in the adductor muscle for the oxidation of cytoplasmic NADH, viz. the malate dehydrogenase system and the Bucher Shuttle. -- The high activities of phosphoenolpyruvic carboxykinase and fructose diphosphatase are compatible with active glycogen synthesis in the adductor muscle, and it appears the dicarboxylic acid shuttle is the mechanism by which the pyruvate kinase step is bypassed, as pyruvate carboxylase is absent. -- The effects of known metabolic regulators of other systems were studied on several of the carbohydrate enzymes of the adductor muscle. Many showed similar properties to mammalian enzymes, although some interesting differences were found. -- Studies on the thermal properties of the enzymes showed that the Km was influenced by temperature and that the effect of some metabolic regulators were temperature-dependent. It would appear temperature may be an important parameter in metabolic control in the scallop.

title: Iterated evolutoidal transformations

abstract: Evolutoids of a plane curve are a generalization of an evolute. They form a one parameter family of curves whose tangents cut the given curve under a fixed angle, which in the case of the evolute is the right angle. The evolutoidal transformation is a point transformation determined by the inclination of t he said tangents and the radius of curvature of the original curve at the given point. Iterated evolutoidal transformations depend on the derivatives of the radius of curvature. The main results of this thesis concern the geometry and structure of the sets consisting of all images of a certain point on the original curve (image-sets) under iterated evolutoidal transformations with varying inclinations of tangents. To my knowledge, a systematic study of such sets has not been undertaken before and several results presented in this thesis are new. A number of special curves, such as sinusoidal spirals and epi- and hypocycloids, appear frequently in this study, in particular, as boundaries of the image-sets. A geometrical construction of the 2nd and 3rd iterations as well as some particular cases of iterations of higher orders reveal interesting connections to elegant theorems of Euclidean geometry. Some of them do appear in old literature, but here they are reinterpreted and proved in a different way.
