abstract: The primary purpose of the study was to determine which mathematics objectives teachers emphasized at the grade six level in Newfoundland and Labrador elementary schools and to analyse the results in terms of basic skill areas defined by leading professional mathematics groups. A secondary purpose was to determine on which of the emphasized objectives teachers spent the most amount of instructional time and which areas of the curriculum were emphasized most. Also examined were the primary methods used by teachers to plan their mathematics program, the difference in emphasis between high and low cognitive level objectives, and the effect years of teaching experience had on the nature of objectives emphasized. -- Twenty school districts in Newfoundland and Labrador were selected at random and from these districts 120 grade six teachers were selected at random. The teachers were sent a questionnaire to collect data on the experience of the teacher and the primary method they used to plan their classroom program. The teachers were also requested to complete a 78 card sort in order to obtain data on the objectives that were emphasized during the 1981-82 school year. Each of the 78 cards contained a test item which represented an objective included in a grade six mathematics program. Complete sets of data were returned by 56 teachers.  -- The four objectives most emphasized by grade six teachers in the sample dealt with skills used in computing with fractions. Other objectives involving fractions also were ranked highly by the teachers in the study. Computational types of objectives generally received high rankings, with division of whole numbers being ranked fifth. When the data were analyzed in terms of instructional time spent it was found that the most amount of instructional time was spent on operations with fractions, specifically subtraction, multiplication and division. Division of whole numbers was ranked fifth. -- With respect to high and low cognitive level items, a significantly higher degree of emphasis was given to low cognitive level items than high cognitive level items. -- The data collected on method of program planning were insufficient to allow analysis. However, from the respondents only six indicated they used the Newfoundland K-6- Mathematics Bulletin as their primary means to plan their program.  -- With respect to the content area being emphasized, number concepts, operations, and problem solving were rated much higher, and therefore received higher ranks than the geometry and measurement content areas. There was no significant difference in the rankings between teachers with different amounts of teaching experience. -- Some suggestions for further study were given at the conclusion of the report. These related to determining if there were sufficient instructional time allocated to mathematics, the effects a decrease in emphasis on computation would have on overall mathematics programming, and a question related to the need to emphasize fractions as much as indicated by the report.

type: Thesis NonPeerReviewed

abstract: Hydropsychidae are represented in Newfoundland by only eight species compared to 145 species in North America. It was predicted that these eight widely distributed hydropsychids would differ in their distribution and ecology here because of the reduced species diversity and the broad diversity of lotic habitats available in the glacial-fluvial morphology of Newfoundland streams. Specifically, that Newfoundland species would differ in their physical niche and that water temperature and food resources would influence their distribution. -- Distribution of Newfoundland Hydropsychidae was strongly influenced by lake outlets, which had higher nutrient concentrations and warmer temperatures than downstream sites. All species occurred in forested and barren landscapes. Densities of hydropsychids were elevated at outlets and in forested streams. Parapsyche apicalis was restricted to cooler streams. Stream size also influenced the distribution of some species. Other physical factors did not correlate with densities. The hypothesized reduced spatial and nutritional competition between species because of the impoverished fauna did not translate into an expanded habitat range in Newfoundland. -- A logistic model was derived to provide a basis of comparison for hydropsychid, plankton and periphyton abundances amongst streams of different sizes. Across stream comparisons showed rapid changes near outlets. Abundances of C. pettiti and H. betteni declined rapidly below outlets, H. slossonae had a fairly constant longitudinal abundance and H. sparna increased in abundance downstream. Zooplankton, H. betteni and total hydropsychid abundance showed similar longitudinal trends.

abstract: Migration has evolved to allow organisms to undertake life history functions in the most appropriate place at the most appropriate time. Migration creates seasonal ecological linkages that have important implications for survival, population dynamics, response to climate change and species conservation. Yet, knowledge of the wintering areas, migratory routes and timing of migration for individual and populations are unknown for most avian species, particularly seabirds. -- This is the first study to electronically track migration and wintering of gannets breeding in North America. Data from band returns and geolocators were integrated to investigate migratory connectivity and the timing and execution of migration in Northern Gannets (Morus bassanus) from four large North American colonies. -- Gannets had distinct wintering areas and aggregated into several major hotspots. Most adults remained along the northeast North American coast closest to their colonies and breeding populations displayed weak migratory connectivity. Unexpectedly, the Gulf of Mexico was revealed to be an important wintering area for adults. Gannets displayed remarkable winter site fidelity with extensive range overlap across years. -- Timing, rates of movement and use of stopovers during migration depended strongly upon winter destination and also upon sex, colony and year. Females departed the colony prior to males in fall but, contrary to prediction, earlier spring arrival of males was not detected. Variation in the ecological constraints operating during different seasons was emphasized by faster and shorter spring migrations in comparison to fall migrations. The repeatability of migratory duration, distance, and timing of arrival and departure from the winter grounds suggested strong individual programs for these traits. However, variability in the timing of colony departure and arrival, migratory speed, and the extent of stopovers en route implies greater involvement of environmental inputs into these behaviours. -- This is the first study to report two strikingly different migration strategies involving trans-Atlantic migration in a continental-shelf migrant seabird. Three gannets displayed a radically different migration and over-winter strategy by undertaking the first recorded (and repeated), wind-assisted, round-trip trans-Atlantic migrations to the coast of Africa, crossing the Atlantic Ocean in as little as five days. The departure timing and routes of west-to-east (and to a lesser extent east-to-west) oceanic crossings were adjusted to maximise the assistance of winds generated by large weather systems; indicating the use of choice in the execution of this remarkable feat for a normally continental shelf migrant. The discovery of this trans-Atlantic connection has implications for interaction, connectivity and phylogeographic radiations between the eastern and western Atlantic populations. -- The observed patterns of migratory timing and scale-dependent connectivity present a novel opportunity to assess the ecological and conservation implications of specific threats during migration and on the wintering grounds. The lability of migratory tactics in the population as a whole combined with remarkable individual consistency in some, but not all, migration parameters offer rare insight into the relative contributions of genetic and environmental factors controlling migration.

abstract: The purpose of this thesis is to develop an FPGA Modular Based Implementation of a Grayscale Morphological Camera for Real-time Applications. A key application is the development of an intelligent camera that satisfies the real-world constraints associated with autonomous vehicles: real-time performance, low power operation, and limitations on weight and size. -- This intelligent camera consists of an image sensor and a programmable logic device called an FPGA (Field Programmable Gat e Array) that serves as a reconfigurable hardware preprocessor. This preprocessing can filter out information that may be regarded as less relevant, while preserving the important structural properties of an image. Processing functions on the preprocessor include histogram generation, edge detection and mathematical morphological operators. Although computationally expensive, mathematical morphological operators are a class of powerful image processing tools for applications such as detecting small targets in cluttered environments, as might be required by an intelligent camera. -- FPGA devices have a significant advantage over serial CP Us and DSPs due to their extremely high throughput rate and ability to exploit parallelism. This research aims to make use of these advantages with t he development of a modular-based approach to implement grayscale morphology. Since t he process of capturing the image is independent of the image processing, this modular approach has the flexibility and scalability of design to allow for non-fixed algorithms that utilize morphological operators with weighted structuring elements of variable size and shape. This is an important first step in the development of an intelligent camera.

abstract: The present study investigated the effects of chronic low and high dose caffeine and aspartame on food intake and anxiety like behaviour in male Wistar rats. Anxiety-like behavior was assessed in the holeboard and elevated plus maze. Rats received caffeine (3.125 x 10⁻¹ or 9.375 x 10⁻¹ mg/ml/day) and aspartame (2.5 or 7.5 mg/ml/day) in their drinking water for 7 days. Rats were then tested in the holeboard and elevated plus maze. High caffeine with and without aspartame decreased food intake relative to vehicle controls. However, rats treated with high caffeine alone developed a tolerance to the anorectic effects of caffeine while low or high doses of aspartame blocked this tolerance to high caffeine. A low dose of caffeine given with a low dose of aspartame synergistically reduced feeding. This suppression was transient. There were no anxiogenic effects in the holeboard and plus maze tests for any group, although baseline anxiety levels were high for all groups. Future research should examine the feeding suppression effects by high doses of caffeine over an extended period in addition to carefully controlling rats' basal levels of anxiety.

abstract: The research herein concerns reproduction in the zooplankton Daphnia pulex. Chapter One introduces the discipline of sexuality research and the model organism D. pulex. The first of my two investigations focused on the possibility that the common intracellular parasite Wolbachia is responsible for reproductive life-history traits among populations of D. pulex from the Great Lakes watershed of North America (Chapter 2). No evidence of any such infection was found among populations exhibiting a variety of Wolbachia-like phenotypes. My second investigation explored the effects of crowding and maternal age upon reproduction among both facultatively parthenogenetic (occasionally sexual) and obligately parthenogenetic (strictly asexual) lines of D. pulex (Chapter 3). Crowding was found to increase resting egg production and reduce neonate offspring production among other effects. Inter-genotypic differences were often significant, as were genotypic responses to crowding. Chapter Four suggests improvements to methods of research and effluent testing using Daphnia, and proposes a large-scale life-history investigation.

abstract: This study focused on the variables associated with the career drifting pattern of a sample of youth and young adults in the province of Newfoundland. Career drifting, based on the research surrounding career indecision and career indecisiveness, was defined as a combination of three career changes since completing high school. The sample consisted of 85 persons between the ages of 21 to 30 years, who previously had held jobs and had attended post-secondary institutions. Using the survey method, the study examined as variables the personality traits of anxiety, locus of control, self-esteem, parental and community factors, employment background and the meaning of work, post-secondary efforts, quester characteristics, person/environment fit, personal aspirations and self-ratings of ability. Analyses suggested that the personality traits of high anxiety and low self-esteem have a relationship with career drifting, however in contrast with previous research, external locus of control was not a variable evident in this group. Results indicated a moderate relationship between parental and community factors and career drifting. Findings suggested that the post-secondary environment and an individual's effort were a greater influence on non-completion of post-secondary programs than that individual's self-rated ability and marks in previous programs. Results revealed that while rating themselves highly as risk-takers, this sample displayed a reluctance to enter into academic and employment situations which they perceived as having a high level of difficulty. Difference between gender and community size were presented for these variables. Finally recommendations for future research are suggested.

abstract: University students' intentions to seek help for hypothetical academic problems were examined in the context of Bartholomew's (1990) four-category attachment model (using both prototype and internal working model scores) and Elliot's (1999) model of goal orientation. Undergraduate students (N = 201; aged 18-42 years, M = 20.2) completed the Relationship Scales Questionnaire (Griffin & Bartholomew, 1994a), the Achievement Goal Questionnaire (Elliot & McGregor, 2001), and the General Help-Seeking Questionnaire (Wilson, Deane, Ciarrochi, & Rickwood, 2005). ANOVA and regression analyses revealed that internal working models of other (p = .009) and mastery-approach goal orientation (p = .013) were the best predictors of academic help-seeking among the variables tested; mastery-approach was also the best predictor of help-seeking from formal sources (p = .033). Combining attachment and goal orientation improved prediction of academic help-seeking. Inconsistencies with previous literature are noted and directions for future research are suggested.

abstract: Computer technology has been in schools since the early 80s. Information Communication Technologies (ICTs) have been incorporated more at the junior high and senior high than at the primary and elementary level. Boards have often focused attention on the senior grades. Primary and elementary teachers have received little support with the integration of technology into classroom settings. Many primary and elementary teachers have not adopted technology as another tool in their classrooms. There are many reasons for this, one of which includes the lack of training for teachers in how to successfully integrate technology into teaching and learning. Professional development in the area has progressed through three stages with the most current being “just-in-time”. There is much research telling why we should use technology and how. This work, an electronic handbook, is a justification for the use of technology in the lower grades. It offers research that supports why teachers should use technology and its curriculum connections. It also includes sample lessons from K-6, ideas of how to use one computer in a class, and links to relevant web sites that are appropriate for both teachers and students.

abstract: The growth and development as well as the chemical composition of lingonberry (Vaccinium vitis-idaea L. ssp. vitis-idaea) cultivars 'Splendor' and 'Erntedank' were studied. The cultivars were propagated using conventional softwood cuttings ex vitro (SC) or by in vitro adventitious shoot regeneration from excised leaves of micropropagated shoots (TC). Morphological data, which includes stem number, branch number, leaf number and fruit yield, diameter and weight, were collected after four growth seasons. Chemical analyses for leaf chlorophyll content and for anthocyanin content and antioxidant activity of the fruit were performed. -- The results of this study indicate that TC plants exhibited significantly more vegetative growth than SC plants thus making TC plants ideal candidates for rapid establishment in the field. While the fruits of SC plants had higher levels of anthocyanins as well as increased production of larger fruit, the TC fruits showed a greater antioxidant activity to compliment its superior growth and development. 'Erntedank' out-yielded 'Splendor' in berry production although the larger fruit were produced by 'Splendor'.

abstract: Although software projects continue to grow larger in size and complexity, the typical methods for debugging these projects have not changed much over the past decade. Software is more modular, with code reuse becoming very common. This can lead to bugs manifesting themselves in one or more sections of code, but originating in a completely different area. This thesis focuses on the development and study of ImpactViz, a novel debugging tool that considers the object oriented nature of modern software languages such as Java, and uses visualization techniques to aid in identifying the potential origins of software bugs. Results from a laboratory evaluation help show that participants find the new program ImpactViz to be both useful and easy to use. The field trials performed have also helped define the benefits and limitations of using ImpactViz in certain situations.

abstract: The objective of this study was to determine which type of repetitive muscle contractions induces a greater acute impairment of elbow position sense. Eleven male subjects participating in the study underwent (i) a fatigue task (FT) consisting of 9 sets of 10 voluntary isometric, concentric, or eccentric contractions randomly performed on three separate sessions, and (ii) pre- and post-treatment maximal voluntary isometric contraction (MVC). Prior to and between sets of FT, a proprioception task (PT) consisting of matching the right arm to the left reference arm was performed at three different target angular positions (70°, 110° and 150°). Each set was immediately followed by 3 PT and 1 minute rest. The statistical analysis revealed that post-treatment MVCs were significantly decreased compared to pre-treatment MVC in all conditions with a greater drop following the eccentric session. Despite this greater drop, position sense was only significantly affected by the concentric exercise session. In addition, matching errors tended to be larger at 110° compared to the other angles. The results showed that concentric muscle contractions impaired position sense in the midrange angle of the elbow joint and this should be taken into consideration when designing proprioception rehabilitation programs.

abstract: This study presents a treatment outcome evaluation model designed for the Waterford Hospital Addictions Program, St. John's, Newfoundland. Because this program operates under the constraints of limited resources, the researcher endeavored to design a model that enables program personnel to conduct manageable but methodologically sound program evaluation. The following factors guided the development of the proposed model: (a) a review of the state of the art evaluation technology, and (b) a preliminary evaluation of the Addictions Program based on an analysis of present implementation policies and procedures, and on a survey of participants' perceptions of the program. The purpose of the survey was three-fold: (a) to conduct a preliminary evaluation of the effectiveness of the Addictions Program, (b) to provide a basis for selecting measures of treatment outcome success for inclusion in the proposed model, and (c) to determine the usefulness of the questionnaire (Appendix C) for inclusion in the proposed model. -- The model includes forms designed to facilitate the gathering and recording of information deemed necessary to demonstrate the impact of the Addictions Program on clients. The rationale for instrumentation and guidelines for implementation are provided.

abstract: As the offshore industry matures on the Grand Banks, the desire to tap into more marginal oil and gas reserves will be realized and efficient exploitation will be required. A study has been undertaken to enable evaluation of wellhead protection concepts for subsea marginal developments located on the Grand Banks of Newfoundland. The study has focused mainly on concepts that maintain probability of well blowout as a result of freely floating and scouring icebergs below accepted levels of risk. The investigation provides a framework from which intelligent decisions can be made regarding the relative benefits and costs of different protection concepts. -- In order to represent both ends of the spectrum in terms of size and architecture, two subsea marginal field development scenarios, considered typical for the area, were selected. These include (1) single well and (2) clustered multi-well developments tied back to an existing production facility. -- A thorough overview of existing wellhead protection technical solutions such as Open Glory Holes, Cased Glory Holes, Caisson Wellhead Systems and Protective External Barriers were presented. Existing failsafe systems such as surface controlled-subsurface safety valves (SCSSV's) were also investigated in detail to determine their reliability and potential effectiveness for protection against uncontrolled well blowout in the case of catastrophic wellhead damage due to an iceberg encounter. -- A minimum risk acceptance criterion associated with wellhead protection in the region was established to be less than 1 x 10⁻⁵ per annum. Utilizing existing methodologies developed from simple geometric models along with the appropriate iceberg data, an analysis was performed in order to determine the encounter and contact probabilities to wellhead facilities as they relate to the various protection concepts. -- To support the selection and decision making process, a cost analysis was performed. The methodology used in the analysis involved a full comparison of capital expenditure (CAPEX) incorporating the risks associated with iceberg contact. Consequences resulting from an iceberg contact such as lost production, environmental cleanup and replacement I repair costs are factored by the probability of that event occurring. -- Results of the study indicate that SCSSV's and other fail-safe systems offer an obvious solution for reduction in overall risk and up-front development costs. The cost analysis indicates the "Modified Cased Hole" protection concept to be most attractive protection solution from a combined cost & risk approach. A conventional "unprotected" subsea well installation for the Grand Banks may prove to be a feasible development scenario given further research. -- Additional work is recommended addressing issues such as well downhole response mechanisms, SCSSV reliability and refinement to the inherent conservatisms & limitations in well blowout probability calculations.

abstract: The purpose of this multiple case study was to gain insight into how instructional designers conceptualize learning objects and their attributes. The 10 participants were instructional designers working in Canadian colleges and universities. Data were collected during two phases of semi-structured phone interviews. Open, axial and selective coding were used to analyze data. Designers identified the following attributes of learning objects: adaptable, assessable, design accountable, digital, granular, interactive, interoperable, pedagogically assessable, pedagogically powerful, pedagogically purposeful, reliable, retrievable, reusable, scalable and usable. Designers defined and conceptualized learning objects and their attributes with a focus on learning theory or pedagogical best practices rather than a focus on technical definitions of learning objects and their attributes. Video games were highlighted by some designers as appropriate analogies for learning objects as they feature interactivity, clearly stated objectives and assessment.

abstract: This thesis examines the occupational folklore and folklife of bar musicians in St. John's, Newfoundland. In carrying out the research, three methods have been employed: formal interview, participant-observation, and questionnaires. Eleven musicians were interviewed and the performances of many more observed in a number of bars in or close to the downtown area of St. John's. Questionnaires were distributed to the bar patrons who made up their audiences. -- Rather than taking a generic or biographical approach> as has been previously used, a locus, the bars in which musicians perform, is the principal focus. -- The main objective of this study is to describe and analyze what it is that musicians do each night in the bars. Before this examination could be made, a descriptive framework had to be developed within which to view bar behaviour. Accordingly the thesis is divided into three major sections: the first offers a description of the bars, noting their types, clientele, physical structure, and management; the second examines the attitudes and expectations of performers towards professionalism, the union, management, status, and role; the third discusses performer/audience relationships and interaction. -- It was concluded that in order to survive in the bars, musicians must employ a number of occupational strategies which are used to counter the often disruptive effects of audience behaviour. Such strategies are as much a part of the work technique as the performance of a song. They are enacted to deal with such hazards as drunks, troublemakers, and inattentive audiences. These strategies are learned through the constant doing of the job, as musicians learn to anticipate possible situations and encounters in the bar and to reflexively respond to them.

abstract: This thesis is a discourse analysis of three Edinburgh-based ghost tour companies: Mercat Tours, Witchery Tours and City of the Dead. It explores the attitudes, values and aesthetics of these companies and their construction and presentation of self-images to their audiences. It identifies key characteristics of the tours and links them to important themes in scholarship on contemporary tourism. Firstly, the construction of an ideology of authenticity within the Mercat Tours discourse exemplifies the model of modem tourism as a "quest for authenticity" (MacCannell, Tourist). In contrast, the light-hearted performance aesthetic of Witchery Tours reflects recent scholarship on postmodern- or post-tourism, in which tourism is seen as a playful game rather than a serious quest. Lastly, the case of City of the Dead offers an insight into the role of fear as a motivating factor in visits to tourism sites.

abstract: Objective: The current study was designed to compare global gene expression profiles of subcutaneous adipose tissue (SCAT) from obese and non-obese young men using whole human genome microarrays. -- Research methods and procedures: Sixteen healthy young men aged 20-27 participated in the study. Total RNA was isolated from SCAT, and competitively hybridized with a universal human reference RNA to Agilent's 44K whole human genome chip. A paired study design was used; ratios for each obese individual were directly compared to those of a matched non-obese individual. -- Results and Discussion: We identified 114 significantly up-regulated and 204 downregulated genes and transcripts in obese SCAT, 232 of which have defined names. For 181 of the genes with defined names, adipose tissue expression has not been reported previously. Gene Ontology (GO) analysis revealed an over-representation of genes involved in apoptosis, cell adhesion, cellular morphogenesis, and cell growth as up regulated in obese subjects. Genes with functions in the mitochondria, including genes involved in ATP coupled electron transport, were down regulated in obese subjects. Clustering analysis identified a sub-set of 27 genes that was able to accurately distinguish obese from non-obese subjects. Moreover, numerous genes that may influence the rate of lipolysis were also found to be differentially expressed.

abstract: In southeastern New Brunswick, located along the Northumberland Strait, shellfish aquaculturists are interested in the option of cultivating sea scallops, Placopecten magellanicus, in shallow water embayments, along with oysters and or mussels. However, sea scallops are not naturally found in the shallow waters of southeastern New Brunswick and environmental conditions at these sites may not be suitable for their culture. The objectives of this study were to investigate the potential for scallop culture in these environments. Laboratory studies were undertaken using two size classes of juvenile scallops (10.0-20.0 mm and 20.1-35.0 mm shell height) to determine their salinity and temperature tolerances. Results indicated that 100% survival was found in salinities ≥25 ppt, and temperatures ≤18°C. The health status of the surviving juvenile scallops was assessed by measuring clearance and ingestion rates, oxygen consumption and secretion of stress related enzymes. The highest indicators for these physiological parameters were observed at 13°C at ambient salinity which was above 30 ppt. -- Field studies were undertaken using the same size classes to examine scallop growth and survival and environmental parameters in four bays, ranging in minimum depth from 3-7 m, in southeastern New Brunswick which are characterized by heavy freshwater inflow during spring and high temperatures (≥20°C) in summer. The scallops held in Bouctouche Bay had the highest survival after 13 months, 84.3% for small juveniles and 88.1% for large juveniles. Lowest percent survival values (0.0 %) were observed in Little Shemogue Bay, Richibucto Bay (sites 2 and 3). The growth rate for small juvenile scallops was the highest in Richibucto Bay (site 1) and Bouctouche Bay (0.061 mm/d ± 0.006 and 0.057 mm/d ± 0.001, respectively). Whereas, for large juvenile scallops the highest growth rate was recorded in Cocagne Bay (0.075 mm/d ± 0.008). -- Overall, based on growth, survival and environmental parameters (mainly salinity), Bouctouche Bay has the best potential of the sites tested for the development of a sea scallop aquaculture site. It is concluded that sea scallop aquaculture farming has a limited future in the region of southeastern New Brunswick. It may be possible, however, at some sites in which the environmental parameters are found to meet criteria that are proposed in this study.

abstract: In the process of defining the emic term “intentional community”, this thesis tells the story of the McMillan House, a Mennonite intentional community in Winnipeg that existed between 2000 and 2007. This thesis also shares the stories of seventeen other young adults who have lived in various intentional communities across North America. This thesis uses ethnography and auto-ethnography to examine the seemingly common association between those who choose to live in intentional community and the often difficult move between moving away from one’s childhood home and inherited traditions to creating a home for oneself and, thus, having the space to discover one’s unique vernacular expression of these said traditions. Through the close and intimate relationships found in their different intentional communities, the young adults interviewed in this thesis found the emotional support they needed to move into the next stages in their life, to come to terms with their varying identities, and to actively live-out their belief in love. This abstract belief in love is expressed tangibly and actively by the participants through things such as environmental sustainability, the overcoming of social alienation, simplicity, and food justice - food justice being the most explored n this thesis.

abstract: An experiment was conducted to determine if the memory loss following electroconvulsive therapy (ECT) was due to acceleration of loss of material from storage or to impairment in the ability to retrieve that still in storage. The method used to distinguish between these two possibilities was recall cuing, which should serve to provide access to any material retained. Twenty psychiatric inpatients heard equivalent lists of words, grouped into five taxonomic categories of three words each, prior to and after a series of bilateral ECT treatments. After each list, two recall periods were given, with three hours between them. Ten subjects were tested by means of free recall, and ten were given category names as cues to aid recall. Recall of words, categories, and words per category dropped significantly after ECT and over the time lapse, but though the administration of ECT resulted in anterograde amnesia, there was insufficient evidence to conclude that the amnesia was due to acceleration of forgetting. Thus, a retrieval-failure hypothesis of the post-ECT amnesia was also not supported, and though cuing resulted in higher category recall, it had no effect on word recall, and did not modify the recall loss over time and after ECT. It was concluded that an impairment in retention or retrieval was not a significant part of the post-ECT memory disorder for the present subjects; rather, the disorder was likely a result of difficulty in getting the material to be learned into storage. Large between-subject variability and the possibility that the cuing procedure was not maximally effective for this group of subjects were also discussed in relation to the findings.

abstract: Parental overprotection has been previously identified as a risk factor for child anxiety. Research efforts are now focusing on the control-related cognition locus of control as a cognitive mediator to explain the relationship between parental overprotection and child anxiety. The purpose of the present study was to identify the different ages at which locus of control functions as a mediator or moderator of the relationship between overprotection and anxiety in children. A non-clinical sample of children (N =146) ranging in age from 7 to 19 years comprised three age groups (8-10, 12-14, and 16-18 years). Participants completed self-report measures that assessed parental overprotection, child locus of control, and child anxiety. Contrary to predictions, significant correlations between the main constructs were found only in the full sample, but not within separate age groups. The lack of statistically significant findings precluded further testing of mediation of moderation models within the age groups. However, testing of these models in the full sample suggested that a non-significant mediation model was a better fit than a moderation model. Differences in the relationships among overprotection, locus of control, and child anxiety may exist when examined across a wide age range compared to when examined by age groups and thus, further investigation with respect to the role of child age is warranted.

Masters thesis, Memorial University of Newfoundland.

abstract: The purpose of this study was to evaluate Level One of the Rehabilitation Certificate Program offered by Memorial University of Newfoundland Extension Service, September, 1978 to December 1979. The study focused on attitude change toward the disabled as a function of the program. The relationship between attitudes toward the disabled and dogmatism, age, sex, level of education and amount of previous contact with the disabled was also explored. -- The two measurement instruments used in this study were the Attitudes Toward Disabled Persons (ATOP) Scale and the Rokeach Dogmatism (OS) Scale. Pre and post test questionnaires were administered to the students, in class, before and after each of the three courses of Level One. The data were subjected to t-tests with the null hypothesis rejected at the .05 level of confidence. -- Findings indicated that a significant change of attitude occured as a result of exposure to Course II. Although slightly positive changes occured as a result of exposure to each of the other two courses, these changes were not deemed statistically significant. A slight, though not statistically significant relationship was found between attitudes toward the disabled and dogmatism. Subjects who held more favorable attitudes toward the disabled tended to hold less dogmatic views. The variables of age, sex, level of education and amount of contact were not found to be statistically related to attitudes toward the disabled. -- A series of recommendations for the future evaluation of this and other programs is suggested.

abstract: As a nature-based religion, it is often assumed that contemporary Paganism would be antithetical to urban life. Yet, Paganism has developed and grown in urban centers as the majority of Pagans continue to dwell there. This seeming paradox is resolved through an examination of the basic tenets of Pagan beliefs, specifically the cosmologies and worldviews of Paganism, and the realities of daily Pagan practices. Despite dichotomies between nature and civilization or rural and urban habitats, Paganism's holistic worldview, in which all things are interconnected and the divine is immanent in all of creation, re-envisions cities as participating in the 'Nature' that Pagans honour. As a defining worldview, Paganism is a lived religion that not only influences perceptions of the city but is in turn influenced by regular interactions with the urban world. A study of urban expressions of Paganism is crucial to understanding Paganism as a viable, dynamic, contemporary religion.

abstract: The aim of this research is to explain how the environmental movement in Newfoundland has responded to the offshore oil industry in this province. It is based on the observation that while environmental groups in other parts of the country have undertaken issues regarding the environmental impacts of the offshore oil industry, groups in Newfoundland, for the most part, have not. In order to explore what factors have contributed to such a response, or lack of response, this research used theories of frames, political opportunities, and resource mobilization. Thirty-seven semi-structured interviews were conducted with members of environmental groups, government, industry, and the private sector, as well as unaffiliated individuals. These interviews provided information about the key factors that contributed to or hindered action against the offshore oil industry. The main findings suggest that resources, opportunities, and frames all played a part in whether action took place and if so, in what form. Both resources and opportunities were important for groups to act, as were their perceptions about these resources and opportunities, i.e. the likelihood that using them would lead to change.

abstract: Functional approaches are introduced to study the structure of marine soft-bottom communities. Results of these approaches, based on the feeding type, microhabitat preference, motility pattern and body size of benthic polychaetes, were compared to one based on taxonomy (families). The material came from grab samples collected from the continental shelf and upper slope off the east coast of Canada, in depths of 85 to 622 m ($\bar x$ = 247 m). Various multivariate analyses are used to identify recurrent biological patterns in macrofaunal assemblages. These patterns are then correlated with environmental variables via canonical analysis. No distinct faunal associations are identified from the various approaches. Instead, there was a gradual shift from one type of faunal grouping to another. -- The value of each approach in characterizing community structure is evaluated in part by the amount of variation explained by the relationship between the biological and environmental data, and by the statistical significance of this relationship as determined by Monte Carlo tests. The recognition of homogenous groupings of samples based on faunal composition and environmental conditions, however, tends to weigh more heavily in this evaluation. With one exception, all functional and taxonomic approaches show statistically significant patterns. The approach based on feeding microhabitat indicates that this biological attribute of marine benthic polychaetes may not play an important role in the structuring of their communities. The functional approach that comprises all functional attributes (i.e. foraging attributes and body size) provides the most meaningful ecological characterization of community structure. In this functional approach, groups of samples along the faunal gradients are strongly associated with large-scale topographic features of the Labrador continental shelf and upper slope. Although the taxonomic approach yields similar results, it does not appear to be as efficient in distinguishing between sample points in multivariate analyses. In functional approaches, interpretation of the results in terms of community structure is greatly facilitated by the direct use of ecological attributes such as foraging mode and body size. -- About half the variation in the biological data can be explained by variables such as water depth, current regime, sediment grain size and benthic biomasses which are associated with two major environmental gradients extracted by Redundancy Analysis. The effect of other biotic and abiotic factors on benthic community structure is discussed. The remaining variability in the biological data unaccounted for in this study may be explained by these factors, other unidentified processes and noise. The spatial scales at which the biological and environmental data are collected may also influence the outcome of a multivariate analysis and its interpretation.

Masters thesis, Memorial University of Newfoundland.

abstract: An apparatus has been designed and constructed to determine accurately, using the pulse transmission method, compressional (± 1%) and shear (± 2%) wave velocities as functions of temperature and pressure. A significant feature of the design, made possible by stacking the piezoelectric transmitting and receiving P and S-wave transducers, is the ability to measure both shear and compressional velocities with each experiment. The device has been employed to study sedimentary core samples taken from wells on the Labrador Shelf and the Grand Banks of Newfoundland. With a few exceptions the results show qualitative agreement with Biot’s theory for propagation of elastic waves through porous solids. Comparison with well log velocities, however, shows significant discrepancies which arise for several reasons. – Velocity anisotropy has been observed between samples taken parallel and perpendicular to the bedding plane. The most extreme case exhibited an anisotropic effect of 10%. The dominant mechanisms proposed to explain anisotropy are crack and pore alignment and inhomogeneous distribution of rock constituents. – The effect of temperature is found to be small compared with the influence of hydrostatic pressure. A 40°C change in temperature in the range studied (7°C - 90°C) does not affect velocities by more than 2%.

Masters thesis, Memorial University of Newfoundland.

abstract: Statement of Problem -- The purpose of this study was two-fold: 1.) to determine the expressed reading interests of beginning grade VI pupils; 2.) to determine the extent to which these expressed interests are reflected in the content of selected basal readers. The basal readers utilized in the investigation were limited to those basal texts which are classified as provincially adopted texts for the Province of Newfoundland and Labrador. -- Procedure -- The study population consisted of grade five pupils who were attending the last four weeks of their school year and had completed the instructional program for that grade. Since the pupils were in the process of being promoted to grade six, they were classified in the study as beginning grade six pupils. -- A questionnaire was designed which contained 171 short annotations based on the various selections contained in the basal readers used in the investigation. Due to the length of the questionnaire it was divided into two parts. Ten annotations which appeared in part one of the instrument were repeated in part two as a measure of reliability. -- A pilot study of the questionnaire was conducted which resulted in minor changes. The final questionnaire was administered to 197 grade V pupils towards the end of their school year. The data were coded on computer cards, analyzed by computer, recorded and studied. -- Results and Recommendations -- The major findings of the study were: -- 1. Differences in the reading interests between boys and girls were significant in ten areas: adventure, mystery and detective, school stories, hobbies, science and invention, sports, and humorous and nonsensical poems. -- 2. Significant differences between boys and girls in the content of basal readers existed for only one text, Exploring Afar. -- 3. Verbal I.Q. significantly influenced reading interests in the areas of mystery and detective, and sports. -- 4. No significant differences existed between verbal intelligence and the content of the basal readers investigated. -- 5. Non-verbal I.Q. significantly influenced the reading interest of pupils in only one category, sports. -- 6. No significant differences existed between nonverbal I.Q. and the content of the basal readers investigated. -- 7. Reading achievement significantly influenced the reading interests of pupils in four areas: animals, mystery and detective, science fiction and biographies. -- 8. Significant differences between reading achievement and the content of basal readers existed for only one text, Voyager 11. -- 9. Chronological age significantly influenced reading interests in two areas: people and places in other countries, and sports. -- 10. No significant differences existed between chronological age and the content of the basal readers investigated. -- As a result of the findings emerging from the study, a number of recommendations were made: -- 1. Further investigations should be conducted at other grade levels to determine the reading interests of pupils. -- 2. Investigations of this type should be undertaken periodically to determine the level of interest of pupils in provincially adopted texts. Furthermore, reading texts should not be purchased without some knowledge of the interest rating of their contents for children. -- 3. Provision should be included in the procedure for adopting basal texts to allow for textbook changes to be made regularly in order to meet the reading interest requirements of school children. -- 4. The Provincial Department of Education should establish a committee which would have as its prime task to assess the reading interests of pupils throughout the province with a view of creating provincial basal readers for the province. -- 5. Schools and school districts should be encouraged to develop adequate library facilities with materials compatible with children's reading interest.

abstract: Cytotoxic T lymphocytes (CTL) are important mediators of cellular immune responses and play a central protective role in many human viral infections. In human immunodeficiency virus (HIV) infection a vigorous antiviral CTL response is induced. However, defining the precise role of HIV-specific CTL over the clinical course of HIV infection has been the subject of much speculation. Because anti-HIV CTL kill infected CD4⁺ and antigen-presenting cells, some investigators suggest that they mediate CD4⁺ T cell depletion, contributing to the immunopathology associated with progression to AIDS. An extensive body of evidence now supports at least a partially protective role for HIV-specific CTL in controlling viral replication and delaying disease progression. However it is also clear that anti-HIV CTL fail to control HIV infection indefinitely. Multiple diverse mechanisms with the potential for contributing to the progressive deterioration of HIV -specific CTL have been shown to arise over the natural course of HIV infection, but the relative contribution of the various mechanisms to CD8⁺ T cell dysfunction has not yet been clearly defined. -- The present study examined properties of anti-HIV CTL at various stages of disease. The primary objectives of the experiments were to further elucidate the biological relevance of HIV-specific CTL, and identify reasons for their inadequate immunoprotective role. The CD8⁺ T cell population that persists through the advanced stages of infection was examined, to determine if characteristics peculiar to progressive infection were imposed on CTL over the course of disease. HIV-specific memory T cell responses of individuals at various stages of infection were examined longitudinally, to identify immunological and virological parameters affecting the maintenance of HIV-specific memory T cells, and to determine the relationship between the expanded CD8⁺CD28⁻ T cell population and disease progression. -- The studies clearly demonstrate that CD8⁺ T cells retain many functional and genetic attributes through the advanced stages of HIV infection. However, an in vivo defect in the ability to generate an effector CTL response becomes evident in the later stages of disease, despite the persistence of intact HIV-specific memory CTL precursors. This defect is overcome with effective therapy, allowing reconstitution of CD8⁺ T cell immune responses, including HIV-specific CTL activity, even following prolonged periods of advanced infection. The accumulation of CD8⁺CD8⁻ HIV-specific CTL was found to be associated with progressive disease, and these cells showed a skewed T cell receptor (TCR) beta chain variable gene (~V) usage and decreased cytokine output in comparison to their CD8⁺CD28⁺ counterparts. Most HIV-infected individuals maintained stable anti-HIV memory T cells over prolonged periods of effective viral suppression, but a minority demonstrated a specific defect in memory T cell maintenance that was associated with present or past CD4⁺ T cell depletion. -- The results of this thesis confirm the importance of HIV-specific CTL in controlling HIV disease progression and identify some of the determinants related to the CD8⁺ T cell dysfunction that is observed concurrent with progression to AIDS.

abstract: Brillouin spectroscopy has been used to determine the adiabatic elastic constants for the hexagonal close-packed (β) phase of solid carbon monoxide near the triple point. In units of 10⁹ N/M², the elastic constants were found to be: -- c₁₁ = 1.909 -- c₁₂ = 1.151 -- c₁₃ = .955 -- c₃₃ = 2.104 -- c₄₄ = .356 -- Each of the above values is subject to an uncertainty of about 4%. However, most of this error is included in a multiplicative factor common to all five elastic constants, and uncertainties of less than 1% remain if this factor is divided out. The elastic constants were calculated from experimental data consisting of 35 Brillouin spectra showing various combinations of the longitudinal and the first and second transverse Brillouin components. The spectra were obtained by using a triple-pass Fabry-Perot interferometer to analyze laser light scattered by a single crystal of β-carbon monoxide with a known orientation. The crystal orientations were established from Laue x-ray diffraction photographs, and a fully algebraic procedure for interpreting the photographs has been developed and described in considerable detail. Derived elastic properties, in particular, bulk modulus, linear compressibility, and Young's modulus, have been calculated for β-CO and the values have been compared with those of four other materials having hexagonal crystal symmetry. A high degree of similarity was observed when comparing the elastic properties of β-CO with those of β-N₂.

abstract: Finite element methods offer versatile tools in structural mechanics to analyze various types of structures. The Finite Element Method (FEM) is extended to Linear Elastic Fracture Mechanics (LEFM) for the calculation of stress intensity factors, crack growth tc., with sufficient accuracy. The conventional FEM applied to LEFM is comparatively complicated since the crack tip region involves the singularities. Higher order conventional isoparametric elements are used in the analysis while near the crack tip, where the singularity occurs, enriched crack tip elements are used. Achieving significant accuracy with fewer elements is one of the main criterion in structural analysis. The method developed here has the advantage of fewer elements with minimal re-meshing and ease of modeling with less concern to aspect ratio. The p-version analysis helps in increasing the order of polynomial without the need tore-mesh and to reuse the same mesh repetitively to get the change in stress intensity factors and eventually the crack growth parameters. Stress intensity factors are a measure of stresses at the crack tip. SIF’s are calculated for various crack problems and results are compared, analyzed and presented.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Dietary lipids are recognized as one of the most important nutritional factors that affect fish larval growth and survival. Rotifers and Artemia sp. are widely used as live-feed during the larviculture of marine fish species. However, these organisms are naturally poor in essential fatty acids, and provide only sub-optimum nutrition to the larvae. The present thesis evaluated the use of commercial products for the enrichment of rotifers and Artemia, and the effects of these enriched live-feed on the early growth, survival and lipid composition of Atlantic cod and haddock larvae. For both species the enrichments tested during the rotifer phase were: 1) AlgaMac 2000®, 2) AquaGrow® Advantage, and 3) a combination of Pavlova sp. paste and AlgaMac 2000®. During the Artemia phase of cod larviculture, the same three treatments were tested in addition to a combination of DC DHA Selco® + AlgaMac 2000® as a fourth treatment. Treatments two, three, and four were tested during the Artemia phase of haddock larviculture. Larvae from both species performed better when fed with rotifers enriched with a combination of Pavlova sp. and AlgaMac 2000. At the end of the rotifer phase, larval dry weight ranged from 1.03 to 1.50 mg for cod, and from 1.03 to 1.10 mg for haddock. The larval lipid composition of both species was affected differently by the treatments. During the rotifer phase, larvae from both species maintained high levels of DHA (22:6ω3) while levels of EPA (20:5ω3) decreased significantly. During the Artemia phase, cod larvae fed with AlgaMac 2000-enriched Artemia and haddock larvae fed with DC DHA Selco + AlgaMac 2000-enriched Artemia showed the best overall performance. The cod larvae final dry weight ranged from 5.31 to 12.06 mg, and haddock larvae final dry weight ranged from 4.47 to 6.40 mg. Larvae from both species had their lipid composition affected differently by the treatments. However, in contrast to the rotifer phase, during the Artemia phase, larvae from both species accumulated EPA and reduced DHA levels. Results from the present study indicate that two closely related gadoids raised under similar conditions have different growth, survival and lipid composition responses to lipid-enriched live-feed.

abstract: Cancer has long been known as a dreadful disease characterized by uncontrolled proliferation of tumor cells. Despite many breakthroughs in biotechnological fields and the discovery of various potent anticancer agents the need in chemotherapy is still unmet. Cancer develops by various mechanisms and the most common mechanism involves mutations in genes. Topoisomerase II is critical for DNA replication, transcription and chromosome segregation and is a well validated target of anti-neoplastic drugs including the anthracyclines and epipodophyllotoxins. However, these drugs are limited by common tumor resistance mechanisms and side-effect profiles. Novel topoisomerase IT-targeting agents may benefit patients who prove resistant to currently available topoisomerase IT-targeting drugs or encounter unacceptable toxicities. Quinolones form an interesting group of molecules that have been intriguing the scientific world in recent years. The last few generations have seen the development of quinolone based drugs. They are well known for their activity against a broad spectrum of bacteria. Drugs such as ciprofloxacin, gatifloxacin, levofloxacin have stormed the clinical world within a short span of time. The last few years have witnessed the development of numerous novel tricyclics and tetracyclic quinolones that target mammalian topoisomerase I and II. The starting point of this research was a thiazoloquinolone which was patented by Kyorin/Kyowa-Hallo. This compound exhibited a promising cytotoxic profile in different animal models. -- Using Alchemy-3™, the optimum configuration of the patented compound was determined and based on this a linear tricyclic quinolone scaffold was designed and used in our research as a fundamental pharmacophore to synthesize novel molecules with antineoplastic profiles. -- This thesis is arranged into four chapters. The first chapter gives a brief history of cancer, quinolones and some of the classic synthetic reactions in the synthesis of 4-quinolones. Chapter 2 provides a review of anticancer quinolones structure-activity relationships and outlines the potential medical uses of quinolones apart from their classic use as antibacterial agents. Chapter 3 describes various aspects of synthetic procedures involved in the preparation of novel quinolone compounds and biological evaluation methods. Finally, chapter 4 concludes this thesis with a discussion of a possible future work. Thus, a number of thieno[2,3-b ]quinolones and the corresponding furoquinolones have been synthesized adapting conventional methods. The cytotoxicity screening of the target compounds was performed against HeLa and Kb cell lines. Unfortunately, the compounds have not shown reasonable activity.

abstract: MEDINET is an interface that will allow electronic exchange of laboratory orders and results between heterogeneous laboratory information systems, in real-time. This study was designed to examine the expected impact of Medinet, prior to implementation. It was the pre-implementation component of a two phase evaluation study. -- Study sites included two of the Province's Institutional Health Boards and two Provincial reference laboratories. Study instruments included: a) key informant interviews; b) a survey of laboratory personnel; c) a survey of physicians; d) laboratory turnaround time (TAT); and e) a measure of the accuracy with which orders are transmitted to the laboratory. -- As a result of improved timeliness of results delivery and more accurate transmission of laboratory orders and results, it is expected that the implementation of Medinet will improve information management, reduce unnecessary utilization of laboratory services and enhance the quality of patient care. Several concerns with the implementation of Medinet were identified and discussed. -- Baseline measurements of turnaround time TAT) and order accuracy were established. The post-implementation study, planned for 6 and 12 months after implementation, will assess the impact of Medinet on each. -- Ultimately, study participants would like to see province-wide integration of laboratory information that supports electronic exchange of orders and results between geographically dispersed sites, direct physician order entry (POE) and immediate access to a patient's longitudinal history of laboratory services.

abstract: The archaeology of gentry life in seventeenth-century Ferryland revolves around the excavation and analysis of a large timber-framed dwelling occupied by Sir David Kirke and family more than 350 years ago. The midden deposits associated with the house contained an impressive collection of artifacts, which not only assisted in dating the site and its range of occupation but it also provided a valuable opportunity to learn about the day-to-day activities of this gentry family. Clay tobacco pipes, coins and other datable objects clearly demonstrate that this structure was erected sometime in the 1640s and that occupation continued until the latter years of the seventeenth century - likely coinciding with the devastating French attack of 1696. -- The Kirke house was very large by Colonial Newfoundland standards. The principal dwelling was 21 by 53 feet but there was also a 12 by 22 foot lodging/servants' quarters, an 8 by 8 foot well house and a cobblestone courtyard. This domestic compound underwent a series of structural modifications and improvements over the course of the seventeenth century including the addition of a 14 by 14 foot buttery/pantry and an 8 by 12 foot dairy. These different phases reveal a household that was far from stagnant after the death of Sir David Kirke in 1654. Rather, they show a family that sought to expand upon their existing accommodations and diversify their business operations in light of changing social and economic times. -- The range of activities conducted in this series of buildings included everything from food preparation, cooking and sewing to serving alcoholic beverages in a tippling room, conducting business transactions relating to the family's Pool Plantation, frequently partaking in fine and elaborate dining practices, and possibly providing medical attention to those in need. Some of the latter activities distinguish the Kirkes from the majority of Newfoundland planter society, for the artifacts reveal that they were both literate and numerate, were involved in international commerce that may have relied upon close personal contacts and were surrounded by a diverse, and in some cases rare, collection of expensive household items and personal adornments. -- The Kirkes were not alone in their conventions regarding a lifestyle befitting their social and economic position. A comparison with contemporaneous gentry occupation in English North America illustrates numerous similarities; yet some lifestyle choices were influenced and shaped by specific environmental, economic or social conditions. Comparatively speaking, the Kirke occupation at Ferryland appears to be "average" in terms of architecture but truly exceptional with regard to other material culture.

X-ray diffraction (XRD) patterns were obtained using monochromatic Cu-K-α radiation at 40kV and 40mA on Rigaku DMax 2200V-PC. Profile fitting was performed using Pearson VII and Pseudo--Voigt functions over 5° to 35° and 60° to 110° = 2θ. Furthermore, to our knowledge, it is the first time we introduced XRD spectra modeled using a Generalized Fermi Function (GFF) for asphalt binders. The analysis of the diffraction line broadening in x-ray thin film is analytically calculated and simulated using these functions. The results showed a correlation among Pearson VII, Pseudo-Voigt and GFF. -- X-ray line broadening investigations from the integral width or the full width at half maximum (FWHM) of the diffraction line is used for approximation of the experimental x-ray line profiles obtained from the samples. Asphalt binder samples measured by x-ray diffraction on thin asphalt films, are identified as two factors that correlate reasonably well with aging tendency at low temperatures. From the application perspective, cracking in asphalt pavements in colder climates and rutting in hot climates are on-going problems. Therefore, investigation and understanding of structural and compositional properties of asphalt binders at the microscopic level is aimed at improving the performance and durability of asphalt pavements.

abstract: It is the thesis or this dissertation that the sociopolitical phenomenon, termed anti-Semitism, is not much older than the term itself and is not a mere continuation of the traditional Christian hostility toward the Jews. The latter constitutes only a necessary, but not sufficient cause. Profound changes effecting society as a whole, due to the coincidence of Germany’s national unification under Prussian leadership with the onset of her rapid industrialization, gave rise to modern anti-Semitism. -- The traditional hostility toward the Jews was primarily of a religious nature. In the seclusion of their European ghettos they turned into a pariah caste. By early assuming economic functions disdained by good Christians they were regarded in time as the driving element of the new economic system and were blamed for its disruptive effect on the old religious and social order. -- The changing nature of the Jewish question was revealed during the constitutional debates of the North German Confederation (1866-1870) when the emancipation of the Jews became entangled Ln the conflict between those who wanted to retain the pre-industrial social order and those who proposed a new liberal order, with all its economic, political, legal, moral, and national implications. -- The new phenomenon of antisemitism emerging in the 1870's derived its initial support from those social groups who were adversely affected by the coincidence of rapid industrialization, depression, Kulturkampf and liberal Federal legislation. Political anti-Semitism represented part of an organized social-conservative backlash, and was re-enforced by the rising integral nationalism. Jews were now seen and portrayed in new roles which were explicitly dissociated from their religious background. They were alleged to be the prime movers behind and thus responsible for the negative effects of all these simultaneous radical changes.

abstract: This internship was motivated by a desire to find a solution to the problem of teaching reading effectively in classrooms where a wide range of reading ability exists. The solution proposed, explored, and evaluated during this internship involved leaving the classes intact and using reading material with identical content but written at more than one level of difficulty. -- Material written at more than one level of difficulty was provided by rewriting existing material to a lower level of difficulty and using this material together with the original material. The use of this material was explored in a classroom situation. This approach was then evaluated by examining the feasibility of classroom teachers rewriting existing material and thus providing two levels of material with identical content for use in the classroom, the original and the rewritten. The advantages of using reading material of identical content but written at more than one level of difficulty in a classroom situation and the effects that this approach had on students were also investigated. -- Given the limitations of this report, there is clear indication that the rewriting of existing reading materials to a lower level of difficulty by classroom teachers is feasible, that use of this material together with the original has many advantages when used in a classroom situation, and that there are benefits to students when this approach is used to provide for the range of reading ability in a classroom.

abstract: The purpose of this dissertation is to analyze the role published diaries, letters and memoirs of Canadian soldiers played in shaping, consolidating, and preserving the "myth of the [Great] war experience" in Canada. In Death So Noble, Memory, Meaning, and the First World War, Jonathan Vance argues that, during and shortly after the First World War, Canadian politicians, artists and historians created this myth to soften the horrible realities of the trenches. To justify and explain the deaths of more than 60,000 Canadians, the war was most often portrayed as a positive, if costly, experience that led a colony to full nationhood. At the same time, Canadian soldiers were described as backwoodsmen; natural soldiers who evinced a strong disdain for army discipline. -- Although Vance's interpretation of the Great War legacy in Canada has been well received, the role that Canadian soldiers played in the creation of this legacy has yet to be examined. One approach to this enormous task is to probe the hundreds of published soldier sources composed by members of the Canadian Expeditionary Force (CEF). Granted, they are limited in number compared to total enlistment figures. Thus, no final claim can be made that they speak categorically for the CEF as a whole. Indeed, in some cases, the reliability of individual writers might be quite dubious. Still, these sources exist and are part of the historical record. They have, however, yet to be analyzed systematically. When they are, these unique sources collectively offer some intriguing, if conditional, insights into soldier agency in the process of myth-making about Canada's Great War. -- Published sources suggest that the way Canadian soldiers portrayed the war fits, almost seamlessly, with the "myth of the war experience." This is not only because the myth influenced soldier writings, but also because Canadian soldiers had both embraced and helped to generate it during the war. The latter point is often overlooked. Although the war divided the dominion as much as it united it, these soldier sources reveal that, layer by layer, something of a pan-Canadian "corps identity" developed, at least among many within the wartime CEF. Moreover, this "corps identity" is present in material written at the time, as well as in memoirs published long after it. -- Volunteers had not consciously set out in 1914 to create this identity. However, traveling and training together created an esprit de corps before Canadians even set foot in the trenches. Apart from their shared experience, this rudimentary identity was also based on the retelling of anecdotes, generally detailing the CEF's pioneer disdain for army discipline. The fact that British civilians viewed the CEF as a homogenous unit, often as a result of the CEF's unique maple leaf uniform and cap badges, only heightened the soldiers' sense of collective identity. -- The CEF's participation in major battles, Second Ypres, Vimy, Passhendaele and the Hundred Days, added another, more positive, layer to this newfound identity. Considering that the Canadians Corps sometimes managed to succeed where British or French armies had failed, it is not surprising that many soldiers depicted these battles as the crowning moments of Canada's war effort. After April 1917, the successful storming of Vimy Ridge, soldiers generally showed little surprise about the CEF's combat effectiveness. Many explained this by pointing to the outstanding soldierly qualities Canadians had brought to the trenches. Even though most volunteers came from urban and industrial professions, the belief that many CEF soldiers had, in some shape or form, experienced Canada's vast wilderness was, perhaps strangely, deeply entrenched. In any case, this helped to create the perception that 'colonials' were ideally suited for the war. -- There can be no doubt that the Great War furthered a Canadian consciousness amongst many soldiers of the CEF. By portraying themselves as different, Canadian soldiers created a "corps identity" that set them aside from others. This identity, perhaps based more on perception than reality, strongly coloured these soldiers' memory of the war. It is exactly this perception of a "corps identity" that we see in the countless letters, diaries and memoirs that have been published in the more than ninety years since the war.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Axial vibration generators improve oilwell drilling efficiency by reducing drillstring-wellbore friction. However, tool vibration can cause unwanted vibrations of the drillstring, and thus premature failure of components. The only effective way to benefit from the positive consequences of these tools is to develop vibration models to predict the vibration pattern of the drillstring for any mode of interest, and implement suppression tools, such as a shock sub to isolate the imposed vibration from the rest of the drillstring. -- Transverse vibration, which is coupled to axial vibration, is the main cause of premature failure of drillstrings. Nonlinear coupled axial-transverse vibration of a drillstring with a downhole vibration generator and shock sub is investigated. Analytical elastodynamic and finite element models are developed. -- The Newtonian approach and the "Bypassing PDEs" method were implemented in developing the analytical models and the ABAQUS Explicit solver package® was used to develop finite element method (FEM) models. The bottom-hole assembly was assumed as a multi-span bottom-hole assembly (BHA) and realistic boundary conditions were assumed. The lateral comparison functions for a multi-span BHA and axial comparison functions for a system of hybrid  continuous (step-beam drillstring) and discrete elements (springs and dampers of the shock sub and the equivalent top boundary condition) were developed analytically. The effects of mud damping, spatially varying axial force along the drillstring, bit-rock interaction and lateral contacts were included. Nonlinearities due  to strain energy, geometry, axial stiffening and Hertzian contact forces were also captured in the models. -- The simulation results were used to extract modal characteristics and analyze the downhole vibration trends of a drill string with a shock sub and vibrating tool installed on the BHA. Multi-mode analysis in the expanded Galerkin's method with accurate comparison functions enabled a multi-point contact analysis, multi mode modal dynamic analysis, and prediction of more realistic critical rotary speeds. A simulated shock sub effectively isolated the vibrating tool from the drillstring, while amplifying the tool force at the bit. Analytical and FEM models showed excellent agreement. The models in their current form can be used to guide the design of drillstrings and to predict drilling parameters such as speed and weight-on-bit (WOB) that will result in acceptable vibration levels.

abstract: Gas phase chemistry of ions provides important insight into the reactivity, thermochemistry, reaction mechanisms, and structures of ions without the added complexity of solvent. Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometry is the most commonly used and ideally suited technique to study chemistry of ions in the gas phase. The ICR cell is like a small laboratory with controllable conditions, where ions are trapped and undergo reactions, therefore elementary steps of reactions can be easily tracked. Structural studies employing activation/fragmentation techniques such as infrared multiple photon dissociation (IRMPD) or sustained off resonance irradiation collisionally induced dissociation (SORI-CID) can be easily conducted using an FTICR instrument. -- This thesis presents study of transition metal complexes reactions with neutral molecules in the gas phase. The first kinetic experiments were conducted for the association reactions of unsaturated ruthenium complexes [Ru(bipy)X]²⁺ (X bipyridine, 2-(pyridin-4-yl)-1, 3-benzothiazole, or 5-aminophenathroline) with CO and O₂ to explore mechanism of the ion-molecule reactions in the low pressure environment of the ICR cell. The association adduct complex [Ru(bipy)₂CO]²⁺ was then used to activate C-H or C-C bonds of various alkanes. Computational chemistry was also employed to further investigate the mechanism of the dehydrogenation and demethanation reactions between chemically activated [Ru(bipy)₂CO]²⁺ and alkane molecules. -- Finally, structures and fragmentation pathways of Zn²⁺ complexes with proline were studied. IRMPD spectroscopy in conjunction with computational chemistry was used to explore the structures of the deprotonated zinc-proline complex, [Zn(Pro-H)]⁺, and the singly hydrated complex [Zn(Pro-H)(H₂O)]⁺. Furthermore, fragmentation reactions of deprotonated zinc-amino acid dimer complexes [Zn(A-H)(A)]⁺ (A = proline, sarcosine, alanine, and glycine) were studied using IRMPD and SORI-CID. The different fragmentation channels observed for secondary amine complexes, proline and sarcosine, and primary amine complexes, alanine and glycine, were interpreted by computational chemistry results.

abstract: Early Psychosis Programs have been developed as a solution to reduce delays and improve outcome for first episode psychotic patients. Evaluations of the programs worldwide have found that the programs help reduce symptoms and hospitalizations and improve quality of life. The purpose of this thesis is to evaluate the overall impact of the Newfoundland and Labrador Early Psychosis Program (NL Program) for its patients. Traditionally, programs are evaluated by pre-post methodology. However, this method may have limitations since it does not use standard control groups and any changes seen in the patients from entry to completion of the program may be due to natural events, such as maturation and changes in hormones, since the patients tend to be fairly young. Therefore, this study will test a novel methodology, propensity matching, as an alternative method to evaluate the NL Program. The patients are matched to a national population from the Canadian Community Health Survey (CCHS) on several clinical and social outcomes to determine how the patients differ from the general population at entry into the NL Program and then after two years, to see if they converge back to the population after completing the NL Program. Propensity matching results are then compared to the pre-post results. Analysis of the data found the propensity matching methodology did produce similar results as the pre-post evaluation approach on social and clinical outcomes such as reducing substance use, depression, hospitalizations and suicide, and improving quality of life and vocational functioning. In conclusion, this study found the NL Program is having a major treatment effect for its patients, and propensity matching may serve as a model in future evaluations in mental health research.

abstract: Calix[4]naphthalenes are "basket shaped" molecules capable of supramolecular complexation with neutral species such as C₆₀. They were first synthesized by Li and Georghiou in 1993. Over the past decade much progress has been made towards developing practical synthetic routes to other regioisomeric calixnaphthalenes. To date, the best synthetic route involves a "one-pot" TiCl₄-mediated cyclocondensation of 3-(hydroxymethyl)-2-naphthol, but affords low yields. Since the chemical properties of calix[4]naphthalenes need to be fully explored, there is a need for more efficient methods of synthesizing these types of compounds. -- Ionic liquids, have shown great potential for use in organic synthesis. Several reports have been published which describe the efficient synthesis of cyclotriveratrylene, another basket shaped compound of interest, in ionic liquids. ²⁹,³⁰  In principle, the methodology employed could be applicable to the synthesis of calix[4]naphthalenes. We therefore explored the use of ionic liquids for their synthesis of calix[ 4]naphthalenes. -- Recently, an unusual method for synthesizing the related calix[4]azulene was reported. This synthesis involved a Florisil®-mediated reaction between azulene and paraformaldehyde. We investigated the generality of this process for the synthesis of calix[4]naphthalenes. The synthesis of calix[4]azulene was reproducible and provided us with a unique chance to look at an unfunctionalized "basket-like" molecule and its supramolecular complexation with C₆₀. The low solubility of calix[4]azulene also allowed us to use a unique method for the ¹H NMR and uv-vis spectroscopy studies. We report our methods and results in this thesis. These methods were then used to examine the stoichiometry of complexes formed between two different calix[n]arene with C₆₀.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Resonance is a biophysical characteristic of a subset of neurons in which the voltage response of oscillating input peaks at a preferred frequency. Given the widespread distribution of histaminergic neurons and the known physiology of histamine receptors in the CNS, it was hypothesized that histamine modulates the resonance of pyramidal neurons by shifting the activation and kinetics of the hyperpolarization activated cationic current, Ih. -- Employing standard whole cell voltage clamp recording, investigation of the modulation of Ih was confounded by a time dependent hyperpolarizing shift of Ih. The addition of cAMP to the recording pipette prevented rundown and resulted in a depolarizing shift in Ih activation consistent with an important role for intracellular cAMP in the maintenance and modulation of Ih. -- In the presence of cAMP in the pipette, bath application of histamine, 8-bromo-cAMP, and forskolin, mimicked cAMP-induced changes in Ih. Histamine's action was mimicked by amthamine (H₂ agonist), blocked by tiotidine (H₂ antagonist), and occluded by forskolin, consistent with an H₂ receptor-mediated activation of adenylyl cyclase. H7, a nonspecific protein kinase inhibitor, blocked both the forskolin and histamine-induced effects on Ih consistent with involvement of a phosphorylation event. -- Using the Impedance Amplitude Profile (ZAP) methodology to profile the resonant properties of pyramidal neurons, histamine increased both the resonant frequency (fres) and its magnitude (Q) in a concentration-dependent manner that closely resembled histamine's action on Ih. This was confirmed by application of ZD-7288, an -- irreversible blocker of Ih, which blocked both the histamine-induced action and resonance. -- It is concluded that histamine, acting via H₂ receptor activation of adenylyl cyclase and possibly a protein kinase, shifts the activation of h to more depolarized potentials. This action modulates the resonant behaviour of these neurons, which in tum can influence their oscillatory properties and consequently aid in the synchronization of larger neuronal networks.
