abstract: This internship report considers the role of a district school board program implementation specialist in promoting the use of adolescent literature in junior and senior high schools in Newfoundland and Labrador. It consists of a case study in which one particular program implementation specialist discussed his beliefs about the meaning of this role and about how it might be achieved best. -- It concludes that the participant believed strongly in the importance of adolescent literature, including how the use of it in junior and senior high classrooms helps meet the learning outcomes of the new Atlantic Canada Language Arts Curriculum: Grades 7-9. (hereafter referred to as English 7-9). The case study revealed that, driven by these beliefs, this program implementation specialist was of key importance in promoting adolescent literature through encouraging its use in diverse ways to administrators, teachers, and parents. Giving teacher support as a facilitative leader in this curricular initiative, especially through related in-service, was of particular importance and received positive reaction from teachers overall. However, time restrictions disallowed! this participant to do the in-depth promotion desired. -- The program implementation specialist believed the promotion of adolescent literature could be achieved best by teachers becoming well read in adolescent literature; by a program specialist who is credible and enthusiastic about his or her knowledge related to adolescent literature and who concentrates on providing meaningful and related in-service; and by some changes being made, especially in an arrangement whereby a school board program implementation specialist for Language Arts can focus on this subject at a particular level, (e.g., junior and senior high school), thus enabling the time needed to do in-depth work

type: Thesis NonPeerReviewed

format: application/pdf application/pdf

abstract: Much has been written about Julian of Norwich's theological conclusions that alle schalle be wele and that loue was his menyng. Less attention has been paid to how Julian arrived at these affirmations. It is herein argued that an examination of the two direct questions Julian asked God during her visionary experience demonstrates that theodicy was her purpose. Essentially, Julian was struggling with the most religious of all questions: how could she reconcile the existence of a loving God with the prevalence of suffering and evil in her world? Her world consisted of plague, war, and pestilence, and because every aspect of medieval life held symbolic religious meaning, interpreted and delivered by the Church, social conditions of life could not be disentangled from one's religiosity. These two aspects of Julian's consciousness, her medieval world and the religious meaning assigned to it, are crucial to one's understanding of Julian's central theological concern and are reflected in her questions to God. Julian's vision is an optimistic answer to her anxieties, and although it provided direct emotional consolation, it did not leave her intellectually satisfied. Julian would spend another twenty years studying her visionary insights before the deeper theological meaning surfaced. This intellectual examination transformed Julian's work from an existential theodicy to an enduring theoretical theodicy with which she could be satisfied. This thesis will examine that progression.

abstract: The satisfaction of police officers and their spouses with two 12-hour compressed work week shift schedules and two traditional 8-hour shift schedules was examined. Data were collected from three detachments of the Royal Newfoundland Constabulary using structured interview and questionnaire procedures. Additionally, the Dyadic Adjustment Scale (Spanier, 1987) was used in a follow-up mail survey of spouses to assess the impact of the stress of police work and shift work on the quality of marital adjustment. The instruments were administered from May to September, 1994. -- In each detachment a number of groups were surveyed: the constables working the 12-hour shifts (N = 122); the shift working supervisors (N = 12); the day working supervisors (N = 7); and the spouses of the constables and supervisors working the 12-hour shifts N =77). Comparisons were drawn between the two types of 12-hour shift schedules and between the 12-hour shift schedules and the two 8-hour shift schedules previously worked in the detachments. Comparisons were also drawn between the constables, supervisors, and spouses within the detachments. -- The data provided support for the major hypothesis of this study: workers and their spouses preferred the 12-hour compressed work week shift schedules over the 8-hour shift schedules. There was no correlation between the composite satisfaction scores of workers and their spouses, implying that the factors which foster satisfaction for a worker are different from those which foster satisfaction for that worker's spouse. Surveyed spouses had, on average, a lower level of adjustment in their marriages than did respondents from previously studied non-police families. The workers reported no change in their quality of sleep or their levels of fatigue after the change to the 12-hour shift schedules. The high preference and satisfaction levels were related to the longer periods of consecutive time off and free weekend time. Overall, the 12-hour compressed work week shift schedule appeared to meet the psychosocial needs of most of the police officers and the spouses surveyed.

abstract: The presence of carbon dioxide in natural gas, synthetic gas and liquid streams has prompted the industrial community to examine the properties of carbon dioxide mixtures with the intent of finding novel methods for removing this acidic impurity. Carbon dioxide is also of interest to researchers because it possesses a readily accessible critical point. This has stimulated studies of the phase behaviour and thermodynamic properties of supercritical fluid mixtures, particularly in systems used in supercritical fluid chromatography (SFC) and supercritical fluid extraction (SFE). For both of these applications, it is important to obtain information pertaining to the vapour-liquid phase boundaries for the carbon dioxide mixtures and their thermodynamic properties over a wide range of pressure and temperature. The (CO: + MeOH) system is of interest to applied research on fluid properties because the pure liquids have widely differing critical points. -- There are many experimental issues associated with supercritical fluids, and laboratory equipment must be specially designed to handle these high pressure, high temperature   fluids.  A high  precision  isothermal  microcalorimeter  has been commissioned to measure the excess molar enthalpy of mixing Hm for the mixture at 298.15 K and pressures of 7.5 and 10.0 MPa. A platinum vibrating U-tube densitometer with a specially designed injection system has been used to measure the densities of (CO: + MeOH) mixtures at temperatures from 298.15 K to 523.15 K and pressures up to 20.0 MPa, from which excess molar volumes VEm were calculated. -- The HEmcurves display sigmoidal shapes and negative minima in the methanol-rich regions and were observed at both pressures. A positive maximum at high CO: molefraction, xco2, was obtained at the higher pressure. These results, along with those obtained for (CO2 + MeOH) mixtures from Christensen et al. (1987) at higher temperatures were interpreted in terms of the states of the mixtures and pure components. The volumetric results obtained from the density data showed negative VE results that became much more negative as the temperature was increased.   Reduced excess molar volumes VRm = VEm/ [x(l-x)] obtained at high xco2 showed very large negative deviations from ideal behaviour, indicating strong interactions between supercritical CO2 and molecular methanol.  The VEm data were used to determine the apparent molar volumes and the standard partial molar volumes of CO: and methanol in the mixtures. Once again, the results were interpreted in terms of phase behaviour of the mixture relative to the pure components.

title: The syntax of object shift in Icelandic

abstract: The focus of this thesis is an investigation of object shift in Icelandic within the Minimalist framework. Object shift here involves movement of a direct object or an indirect object from base position to a position higher in the syntactic structure. Adverb placement is often employed as evidence for object shift: in situ elements follow, and shifted elements precede a sentential adverb such as negation. -- A description of the object shift phenomenon is presented in Chapter One. Background research is discussed, including a description of Icelandic verb properties by Holmberg and Platzack (1995), an investigation of the category E by Travis (1994), and work on negator movement by Moritz and Valois (1994). -- Chapter Two illustrates various hypotheses concerning the syntactic derivation of the word order combinations involved in (double) object shift, with an emphasis on Icelandic data. These include work by Groat and O’Neil (1996), Collins and Thrainsson (1993), and Bobaljik (1995). Problems with each of the proposals are laid out after the respective analyses. -- Chapter Three represents an alternative analysis to the previous works. The analysis assumes the lowest position of an indefinite subject and the vP-external position of a shifted direct object to be the same position [Spec, EP]; and overt Shift of the negator to [Spec, NegP] is proposed. Object shift is derived by a process whereby the presence of strong features is triggered in a head whose maximal projection is immediately dominated by the maximal projection of another head which itself contains strong features. The implication of the latter is that shift of an indirect object alone is actually shifting of the indirect object, the negator, and the direct object to higher positions. The posibility of vP-internal shift of the direct object is also raised.

abstract: The main focus of this study was whole language teaching amongst primary teachers, grades kindergarten to three, within the Conception Bay South Integrated School District, The literature was examined with respect to detailed descriptions of whole language philosophy, both in theory and practice. A field survey was conducted with a select group of primary teachers to ascertain their level of knowledge of whole language philosophy and how this knowledge translates into learning experiences for children. -- Scheduled interviews were conducted with the provincial primary consultant with the Department of Education, the language arts program coordinator with the Conception Bay South Integrated School Board, and five primary teachers from schools within the Conception Bay South Integrated School District. A mailed questionnaire was distributed to the 49 primary teachers within the five primary/elementary schools under the Conception Bay South Integrated School Board. Thirty-eight or 78 percent of the questionnaires were completed and returned to the examiner. -- The many advantages and benefits which a whole language philosophy of teaching and learning can offer to teachers and children alike, were strongly evident from the literature. The literature illustrated also, many activities, approaches, and procedures which have the potential to fit a whole language framework. -- Findings from the study revealed that the Department of Education articulates a whole language philosophy in its primary language curriculum guide, and the Conception Bay South Integrated School Board includes a whole language philosophy in its goals for the school district. The results of the survey indicated that the teachers are working within a whole language framework or are heading in that direction. This is not to say that they are textbook examples of whole language teachers; however, they engage in many practices which are consistent with and reflect a whole language philosophy. Those who indicated that they are whole language teachers are well aware of the benefits whole language can offer to children and to themselves, but are equally aware of the problems associated with it, if teachers are not well informed. Concerns were expressed, particularly with respect to support through inservice and other type sharing sessions, deemed essential in the advancement of knowledge of whole language, and in the successful development of whole language teachers. -- Based on findings from this study, recommendations were made for additional support and assistance in the area of whole language, and for further research.

abstract: English settlement of Ferryland and other south Avalon communities, 1630 to 1700, is considered within the context of the early modern West Country migratory cod fishery at Newfoundland. The planter economy diversified but fishing remained the staple resource. In 1638 Sir David Kirke expropriated Ferryland from Sir George Calvert, who had invested in a permanent fishing station there. The Kirkes were wine merchants with commercial connections in London, Spain, the Atlantic Islands, New England and the Gulf of St. Lawrence. Archaeology at Ferryland suggests that Kirke and his partners invested as much as his predecessor. The Kirkes profited from their Newfoundland investment and remained important planters until 1696. -- The over-wintering population of the English Shore reached about 1500 by 1660 but did not grow much beyond 1700 for the rest of the century. Documents suggest the 1620s and 1640s were important for settlement in the study area. Demography and mobility rates indicate that heads of households were no more transient than in many communities elsewhere. The society of the English Shore can be understood as consisting of servants, planter employers and a planter gentry of literate merchants. The relation of planters and gentry was a form of clientage. The roles of women and religion are briefly considered. -- Fishermen's incomes in seventeenth-century Newfoundland were not as low as often assumed nor did payment by wages replace shares in this period. Comparative statistical analysis of archaeological assemblages confirms documentary indications that wine and tobacco were major components of demand. These preferences were related to contemporary consumption patterns and terms of exchange at the fishing periphery. These little luxuries functioned as symbols of warmth and sociability. Both supply and restriction of these goods can be understood as forms of social control. Retarded development c. 1700 had as much to do with devastation of the English Shore by the French, as it did with economic factors such as wage levels or socio-cultural factors such as consumption preferences.

abstract: The purpose of the present study was to examine the attitudes of both younger and older adults toward two target groups -older adults (65-74 year-olds) and younger adults (18-25 year-olds). This study was also designed to assess the importance of cognitive and affective information in predicting attitudes toward the elderly. As expected, when an evaluation thermometer was used to assess attitudes toward older targets, results revealed that both younger and older adults held positive attitudes toward the elderly and that older adults evaluated others more positively than did younger adults. In addition, the results of this study suggest that older and younger participants do not differ in their evaluations of younger and older targets. -- Although past research suggests that gender plays a role in determining attitudes toward older adults, these findings were not supported in the present study. Results revealed that older male and female targets were evaluated similarly regardless of the respondents’ gender. In addition, no relationship was found between contact with elderly adults and attitudes toward this group. -- The results of the present study only partially support the tripartite model of attitude formation. When stereotypes, emotional responses, symbolic beliefs, age of target, and age and gender of participant were used to predict attitudes toward older targets, only affect was found to be a significant predictor of attitudes. In addition, none of the above variables predicted attitudes toward younger targets. The implications of this finding are discussed and suggestions are made for future research.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: The primary purpose of this study was to further the understanding of the deposit-feeding strategies through an overall comprehension of the environmental and physiological constraints and the feeding opportunities encountered by the obligate deposit feeding protobranch Yoldia hyperborea . -- Seasonal variation in the feeding response by Yoldia hyperborea from the deep-depositional zone of Conception Bay (∼250 m) was monitored through periodic quantification of morphological (digestive cell height) and biochemical changes (protein content, activity of acid protease and α-amylase) in the digestive gland. Results showed an increase of digestive cell height and protein content as soon as sinking organic material from the spring bloom fallout reached the benthic zone, suggesting storage of metabolic energy during spring and summer, this was followed by a decline of both variables in late summer, coinciding with gamete development. Sharp increases of digestive enzyme activity occurred only in early spring of each year, coinciding with the timing of the primary bloom fallout, and suggests activation of the formerly depressed lysosomal system after a prolonged period of low food availability ( i.e. late summer to autumn). Individuals exposed to laboratory simulated events of sedimenting algae showed an increase of digestive cell height to similar levels observed in the field, whereas digestive cell height in animals exposed to impoverished sediment remained at the low levels shown by animals within the inter-bloom period. -- Yoldia hyperborea is primarily a sub-surface deposit feeder, but switches to surface deposit-feeding when surface sediment is enriched with algae. Behavioural changes to the downward flux of sedimenting microalgae was displayed as it extended its siphons into the water column when suspended algae were in high concentration. This behaviour was followed by partial reemergence of individuals and extension of the palp proboscides over the sediment surface once suspended algal concentration decreased and algae accumulated on the sediment. Concurrently, orientation of the siphon changed from vertical to horizontal, thereby always keeping closer contact with the area of highest algal concentration. In contrast, activity of animals not exposed to algae was primarily restricted to strata below the sediment surface. -- Siphon extension into the water column and active ventilation during periods of high suspended algal concentration suggest active suspension-feeding during algal sedimentation events, although deposit-feeding would be resumed once suspended algae decreased. Despite the fact that feeding experiments demonstrated the feasibility of suspension-feeding behaviour in Yoldia hyperborea , ingestion rates were extremely low and individuals were not capable of meeting their metabolic energy demands, although absorption efficiency of organic carbon was high (50-72%). In contrast, high ingestion rates (4.358 mg sed. • ind⁻¹ • h ⁻¹ ) were observed during deposit-feeding on algae-enriched sediments, which together with high assimilation efficiency of algae-derived organic carbon (87.7-95%), supplied sufficient energy to meet metabolic demand and provide a positive scope for growth. -- The results of both field and laboratory studies suggest that the suite of behavioural changes displayed by Yoldia hyperborea during algal sedimentation events are linked to its nutritional dependence on this food source.

abstract: This thesis is concerned with the study of text-tune relations in the song complex of a Newfoundland local song, The Moonshine Can. The aim of the work is to examine the combination and re-combination of words and music in the complex, and to account for their interrelations. -- The song complex comprises the extant versions of The Moonshine Can, from both folk and popular traditions, and the other songs known to have been sung to its principal melody. The texts and tunes of these songs are analysed and compared within the framework of a diachronic model, incorporating consideration of the people, places, historical periods and events referred to in the songs, and the songs' composers and re-creators. A synthesis of the various levels of the model produces a life history of the song complex and a theory of the text-tune relations evidenced in it. -- Attention is directed towards the elucidation of the content of The Moonshine Can with reference to illicit distillation in general and the particular incident portrayed in the song. The manner of the song's composition and contexts and styles of its subsequent performance are also described and a detailed study made of its text and tune variants. The Newfoundland recompositions and re-combinations of The Moonshine Can are then presented and the nature of their relationship to the The Moonshine Can explored. This leads to an exposition of the life history of the song complex and the dynamics of its text-tune combinations.

abstract: Educational restructuring is changing curriculum, instructional design, and classroom practices. In today's learning environment, students are actively engaged in their learning, enabled by access to a vast array of multi-sensory resources. One of the driving forces behind this change is technology, and educators must begin to use the tools provided by it or the future may overcome them. -- A radical change, in philosophy and conception, brought about by technology, is also altering the environment of the school library resource centre, its programs, and the role of teacher-librarians to more accurately reflect the environment in which they function. The increase in electronic and interactive media has transformed the school library resource centre from a repository of books to an information technology centre. A new information literacy has evolved to access, analyze, apply, create, and communicate that information. The teacher-librarian no longer manages a collection, but rather integrates technology into the curriculum through cooperatively planned and taught units of study. -- School library resource centres and their programs, as well as teacher-librarians who have not kept pace with these changes or constructed a vision for thefuture, may not be empowering students to be independent, life-long learners.

abstract: Women in fishing communities have always been involved either directly or indirectly in the fishing industry, yet their involvement has sometimes been overlooked. In recent decades, changes in both the global fishing industry and the economy have often negatively impacted the lives of India's traditional fisherfolk, a marginalized coastal people. Much can be learned from their experiences. This report examines the experiences of women in two fishery dependent areas of India for their wider lessons. -- From 1952 to 1972 several villages in Kerala, India, received Norwegian fisheries development assistance - the first bilateral development agreement in the Third World. The Indo-Norwegian Fisheries Project (INP) was a community development project that emphasized fisheries development. The construction of a health clinic and wells for safe drinking water have benefitted the women fisherfolk of the area. During another fisheries development initiative in the early 1980s, the Indian government introduced trawlers to several villages in another state, West Bengal. The mechanization of the fishing industries of both Kerala and West Bengal displaced women from traditional activities and changed their work roles. -- These cases are not exceptions; they illustrate a global phenomenon. Industrialization has generally, in the long run, negatively impacted the lives of small-scale artisanal fisherfolk, those most dependent on fishing for subsistence. In response to changes in the biological, economic and social dimensions of the fishing industry India's fishworkers have organized to gain a voice in the decision-making affecting their industry and lives. -- This report concludes with recommendations toward a more beneficial approach to development planning for arsitanal fishing populations. This goal may best be realized by balanced consideration and representation of the voices, roles and needs of both fishermen and women in their industry and community.

abstract: This study gathered descriptive information on the status of classroom-based delivery of speech and language services in Canada. A sample of Canadian speech- language pathologists working in schools were surveyed using a questionnaire mailed in March, 1996. By June, 1996,253 usable questionnaires had been received, resulting in an 82% return rate. A total of 73% of respondents spent time on intervention in classrooms. The mean percentage of time spent was 22.1%. -- Seven service delivery approaches for classroom-based intervention, ranging from least collaborative (Approach One) to most collaborative (Approach Seven), were listed on the questionnaire. Respondents were asked to indicate the approaches they had used. Use was compared to respondents’ personal, professional, and situational characteristics. Results of chi-square analyses revealed no pattern of significant relationships among variables. -- Respondents were questioned about their use of the seven classroom-based approaches with four disorder types and four grade level categories. Additionally, they were asked to judge the success and appropriateness of the approaches. The approaches were used by the largest percentages of respondents for language disorders, followed in order by those for articulation, fluency, and voice disorders, and for students in Kindergarten to Grade 3, followed in order by those for Grades 4 to 6, Grades 7 to 9, and Grades 10 to 12. The approaches were judged successful and appropriate with all disorder types and all grade level categories by a majority of respondents who used them. -- Respondents were asked to rank advantages and disadvantages of the approaches to speech-language pathologists, teachers, and caseload and non-caseload students, and factors that encourage and discourage use of the approaches. The chief benefits of classroom- based service delivery were considered the increased harmonization of speech and language goals and curriculum goals and the carryover of speech and language skills to the classroom. The prime drawbacks of classroom-based approaches.were judged to be the additional time required for planning and the de-emphasis on individualized programming for students requiring speech and language services. The largest factor facilitating the use of classroom-based intervention was perceived to be teacher support. The greatest constraining factor was considered lack of time. -- Respondents were queried on needs for further information about the approaches and preferred methods of obtaining information. A large majority of respondents perceived that further information is needed for speech-language pathologists who use classroom-based approaches. The area of greatest need was judged to be curriculum content. The preferred method of obtaining information was inservices or conferences. -- Chi-square analyses showed that for all disorder types and grade level categories, the approaches were judged more appropriate by respondents who had used them than by respondents who had not used them. Nondirectional independent samples r-tests were conducted to test for differences between the views of the two groups on advantages and disadvantages of the approaches to speech-language pathologists, teachers, caseload and non-caseload students, and on factors that encourage and discourage use. The two groups' views on advantages and disadvantages to the four groups were similar to one another, although the groups’ views on encouraging and discouraging factors differed. More respondents who had used the approaches perceived a need for additional information. Respondents in the two groups shared views on perceived areas of need and preferred methods of obtaining information. -- Results of the study are consistent with reports in the literature on the use of classroom-based approaches by speech-language pathologists. Its findings reflect the speech-language pathologist's current shift from a diagnostician of speech and language disorders to a language specialist who collaborates with teachers through use of a holistic approach to students' communication needs.

Masters thesis, Memorial University of Newfoundland.

abstract: The object of this thesis is to compare the practice of giving offerings to the fairies between two broad groups: the traditional or folk cultures of the Celtic areas and contemporary Earth-Centred spiritual groups. These offerings are discussed in terms of form and function in each of the two groups, and compared between groups. -- The data for this study comes primarily from printed sources in the case of the folk tradition and printed and online sources in the case of Earth-Centred Spirituality. Information for both groups has been supplemented by personal communications and e-mail correspondence. -- The emphasis of this thesis is on comparison between the folk tradition and Earth-Centred Spirituality, however, differences within each group are also noted. Most people following Earth-Centred Spiritualities have looked to folklore to some degree for inspiration or at the very least for enjoyment. It is this which forms the basis for the relationship between the two groups.

Masters thesis, Memorial University of Newfoundland.

abstract: This thesis begins by reviewing the mandate of Newfoundland and Labrador Adult Correctional Services with specific emphases on the service's position regarding rehabilitation, and some of the assumptions underlying its mission statement. The degree to which false assumptions and under-explored external and internal factors have combined to hinder the quality and quantity of rehabilitative programs at the Newfoundland and Labrador Correctional Center for Women (NLCCW), form the main crux of the thesis. Internal factors considered include offender demographics and correctional officer work orientations. External forces consist of the location and structural design of the institution, as well as social, political, and economic considerations. Data, largely in the form of semi-structured interviews, were collected between April and June, 1999. Key informants included female prisoners, correctional officers, prison administrators, and treatment personnel. These data are augmented by selective observations and secondary sources. Findings are informed by concepts and ideas derived from feminist, sociological, and criminological theories of crime, as well as the theory of human motivation. The thesis concludes by providing a summary of the main findings, avenues of future research, and some policy alternatives for interested parties.

abstract: A major challenge for maternal and child health services is the promotion of healthy pregnancy outcomes. In order to improve perinatal outcomes, risks in the prenatal period must be identified and reduced by offering appropriate targeted programs. Clinical and research findings suggest that prenatal care regimens which provide social and behavioral services along with medical care are more effective in improving mothers health and pregnancy outcomes than traditional prenatal programs. In 1994, Healthy Baby Clubs (HBCs) were established in nine regions of Newfoundland. HBCs are based on a peer support model which provides services to high risk pregnant women through a support network of resource mothers, nutritionists, and public health nurses. -- The purpose of this grounded theory study was to describe how HBCs are influencing health-related issues. Interviews were conducted with 20 women attending HBCs in 1999. Results, using the constant comparative method of analysis indicated three theoretical constructs: creating a supportive environment (facilitating access to HBC, providing supports, reinforcing healthy food choices), becoming empowered (acquiring knowledge, encouraging healthy behaviors, increased self-confidence, giving recognition to unmet needs), and evolving social self (valuing social contact, sharing experiences, improved family relations). Findings suggest that HBCs exerted a positive impact on participants1 psychological, emotional, and social functioning. The study emphasized the importance of a collaborative approach and incorporating peer support, when providing prenatal care to disadvantaged pregnant women. The findings from this study provide new insights into the needs of pregnant mothers of low socioeconomic status, so that, prenatal care can target their needs and, in turn, improve perinatal outcomes. The implications of this study for nursing practice, nursing education, and nursing research are addressed.

abstract: This thesis considers computer-mediated communications through a case study of a select group of Usenet newsgroups at Carleton University during the Fall of 1999 and the Winter of 2000. At the time that the data were collected for this thesis, Carleton University was the only post-secondary institution in Canada that utilised an Internet discussion group to support all undergraduate and graduate courses offered by the institution. -- Some of the specific areas considered included a content analysis of these Internet discussion groups, the nature of utilisation of these groups, the differences in student usage of these groups based on a variety of instructional approaches, and studentimpressions of their own usage and the usage of their instructors of these Internet discussion groups. -- At the conclusion of this thesis, the researcher was able to determine that there was little student participation in terms of posting messages to the newsgroups at Carleton University. However, the completed student surveys indicated that over half of the students in the class would access the newsgroup on a regular basis.

abstract: This study was part of a larger interdisciplinary Eco-Research program entitled "Sustainability in a Changing Cold-Ocean Coastal Environment", which assessed the impact of the fishery closure on various aspects of individuals and communities in coastal Newfoundland. The purpose of this study was to compare the level of mental distress experienced by unemployed and employed women, in two areas of Newfoundland that were affected by the northern cod moratorium. In addition, the relationships between women's mental distress and a number of variables, which included having a partner, age, level of education, number of children under 16 years of age, partner's employment status, and history and duration of unemployment, were explored. The sample consisted of women between the ages of 25 and 64, who were unemployed (n = 112) and employed (n = 112). Data were collected in the spring of 1995, three years after the moratorium began. Demographic data were collected using the Eco-Research Health Survey (ERHS), which was used in the health component of the study to assess the health status of the participants. Mental distress was measured using the abbreviated 28 item General Health Questionnaire (GHQ28). The findings showed that the unemployed women reported significantly poorer mental well-being in the year prior to data collection as compared to their employed counterparts. At the time of the study, however, the stress levels of the unemployed and employed women were similar, with both groups of women experiencing high levels of distress. The moratorium, financial problems, and feelings of uncertainty were identified as key stressors for all the women, but especially for those without work. It is proposed that although employment can be stressful for women, it may be protective of good mental health for a lot of women. The results also revealed that none of the variables significantly correlated with the level of distress for the unemployed women. Among the working women, past experience with unemployment and level of education had significant correlations with their mental well-being. Recommendations for nursing practice, education, theory, and research were made.

abstract: In the design of ships and offshore structures, it is often desirable to assess the effects of environmental forces such as wind and waves on the vessel prior to its construction. Hence, several computational methods have been developed to predict the seakeeping performance of a prototype vessel in the design stage. Many of the commonly used methods are limited in their applicability to either vessel geometry or vessel operating conditions. The time-domain ship seakeeping simulation code, MOTSIM, has recently been extended for use with multi-waterplane vessels such as semi-submersibles and catamarans. As a further extension, the MOTSIM solver was modified to allow simulation of two vessels connected by a mechanical constraint such as an Articulated Tug Barge (ATB) Unit. -- Some validation studies were carried out to validate the modifications to the MOTSIM code. Model test data for a triangular semi-submersible platform was compared against simulated results. Comparison between the experiment and simulations was generally good except for very low wave frequencies which was likely due to wave reflection in the model basin. -- Similarly, simulations were performed for an ATB unit. Comparison of the connection loads and relative motion between the vessels appears quite reasonable for the limited set of simulations completed. Instability of the constraint algorithm caused a reduction in the number of simulations included in this study. -- The results presented indicate a strong potential for the application of the MOTSIM seakeeping code to problems involving multiple waterplane vessels or multiple vessels in proximity. However, further validation work is needed to confirm the accuracy of the code for more general vessel geometries.

abstract: Transition metal-mediated diastereoselective synthesis is one of the most important and extensively used methods to create chiraiity at carbon and other heteroatom centres. This thesis focuses on chiral induction from an asymmetric, pseudo- octahedral metal centre in the Arbuzov-like dealkylation of prochiral phosphonites. A series of η⁵-cyclopentadienyl, η⁵-pentamethylcyclopentadienyl, and η⁵-indenyl three- legged piano-stool complexes have been studied as chiral auxiliaries. The effects of ligand sphere steric and electronic properties on M*→P optical induction have been examined. -- The synthesis, structure, spectroscopic properties of a series of chiral η⁵-indenyl cobalt complexes are described. X-ray crystal structure and solution conformational analysis showed that all η⁵-indenyl complexes have a propensity to distort away from η⁵ toward η³ coordination, and that the indenyl ring always has certain conformational preferences with respect to the ligands on the metal. Distortion and conformational preferences of indenyl complexes are fully discussed on the basis of extended Huckel molecular orbital (EHMO) calculations, and fragment molecular orbital (FMO) analysis. -- Arbuzov reactions of η⁵-indenyl, η⁵-cyclopentadienyl, and η⁵-pentamethyIcyclopentadienyl cobalt iodide auxiliaries with PR'(OMe)₂ (R' = OMe, Ph) proceed via an ionic mechanism to form the corresponding cobaltophosphonates or phosphinates. Ionic intermediates were observed by ¹H NMR spectroscopy at ambient temperature in most cases and isolated in some cases. -- The following conclusions can be drawn from the results presented in this thesis: (i) The chiral metal center is essential for stereoselectivity, (ii) The steric requirements of the spectator ligands is crucial in determining chiral induction. The bulkier the spectator ligands, the higher the chiral induction. (iii) The stereochemical properties of the entering phosphonites, PR'(OMe)₂ is also important for diastereoselectivity. Large substituent R’ result in high diastereoselectivity. (iv) Intramolecular hydrogen bonding plays a significant role in controlling the stereoselectivity in the Arbuzov reaction by restricting population of solution conformations, maximizing the preference of one diastereomer over another.

abstract: The work described in this thesis deals mainly with the application of the valence isomerization-dehydrogenation (VID) approach, previously developed by our group, to the synthesis of pyrenophanes with extended aromatic surfaces. As ultimate goal a fully aromatic "Vögtle" belt is proposed. -- Key intermediates for the synthesis of pyrenophanes via the VID approach are syn -2,11-dithia[3.3]metacyclophanes. In Chapter 2 the results of a study of the bridge conformational behavior of these compounds is discussed. This behavior is correlated with Hammett's constant (σm ) of the substituents in the 6- and 15-positions. The effect of the solvent is discussed and the study is completed with a DNMR study on several of the 6,15-disubstituted syn -2,11-dithia[3.3]metacyclophanes. -- In Chapter 3, a synthetic effort toward the synthesis of a pyrenophane with two para -phenylene units in the tether is described. In this case the VID methodology fails to give the desired pyrenophane. -- A straightforward synthetic plan for the synthesis of a Vögtle belt is described in Chapter 4. The synthesis stalled due to unavoidable side reactions during ring contraction of an advanced intermediate. -- The synthesis of pyrenophanes with one phenylene unit in the tether is described in Chapter 5. For two such pyrenophanes, [2]paracyclo[2](2,7)pyrenophane and [2]metacyclo[2](2,7)pyrenophane, a successful synthesis is reported, as well as their X-ray crystal structures. In both compounds the tether forces the pyrene unit to adopt a non-planar geometry and a spoons-like orientation of the aromatic decks is observed.

abstract: This thesis describes studies of thiophenophane ligands and their coordination chemistry. In Chapter 1, aspects of macrocyclic thioether chemistry have been briefly reviewed. In Chapter 2, synthesis and characterization of eight thiophenophane ligands are described. The molecular structures of 2,5,8-trithia[9](2,5)thiophenophane, 2,5,8,1 l-tetrathia[12](2,5)thiophenophane and 2,5,9,13-tetrathia[ 13](2,5)thiophenophane have been determined by X-ray methods. The effect of the rigid thiophene subunit with its two attached methylenes on the solid state conformations of the three macrocycles is discussed. In chapter 3, synthesis and properties of 15 copper(I) and (II) complexes of thiophenophane ligands and the open-chain ligand, 2,5-bis(2-hydroxyethylthiomethyl)thiophene, are described. The molecular structures of seven of these compounds are presented and spectral details are interpreted in the light of these structures. The redox properties of the complexes have been examined by cyclic voltammetry and the effect of solvent on their electrochemistry is discussed. In the first part of Chapter 4, synthesis and properties of palladium(II) and platinum(II) complexes of open-chain and macrocyclic thioether ligands are presented. The molecular structure of [PdBr₂L1] (L1=2,5,8-trithia[9](2,5)thiophenophane) has been determined. Variable temperature ¹H nmr spectra show that the open-chain dithioether complexes undergo rapid conformational exchange at room temperature but are configurationally rigid while the macrocyclic thioether complexes, [MX₂L1] (M=Pt, X=C1; M=Pd, X=C1, Br, I, SCN), undergo very limited conformational and no configurational exchange up to their decomposition temperatures. Chemical exchange of acidic ligand hydrogens and a metal-ligand dissociative equilibrium were detected when M=Pd and X=SCN. In the second part of Chapter 4, preparations of seven π-allylpalladium complexes of open-chain dithioether and macrocyclic thiophenophane Iigands are described. The molecular structure of [Pd(C₃H₅)L1]⁺ reveals an asymmetric π-allyl group and a rare, unusually short apical Pd-S(thiophene) bond (2.786(4)A). Variable temperature ¹H nmr spectra of these complexes show that open-chain dithioether complexes undergo rapid inversion at coordinated sulfurs while the complex, [Pd(C₃H₅)L1]CF₃SO₃  undergoes a 14-metallotropic shift on the heteroatoms of the macrocycle at room temperature and a dissociative inversion at thioether sulfurs at elevated temperatures. In Chapter 5, synthesis and properties of thirteen silver(I) complexes are presented. The molecular structure of [Ag₂(L2)₂](ClO₄) ₂’ which contains a centrosymmetric dinuclear cation with a slightly distorted trigonal bypyramidal coordination geometry about each silver atom has been determined. The chemical and photochemical stabilities of these complexes are discussed with respect to the structure of  [Ag₂(L2)₂](ClO₄) ₂²⁺.

abstract: The total synthesis of the sesquiterpene (+)-longifolene by an intramolecular Diels-Alder cycloaddition strategy is described. The route utilized an addition initiated ring closure involving methyllithium and epoxyfulvene 80. The cyclopentadienyl anion 81 that resulted cyclized in an exo-tet manner to generate a substituted spiro[2.4]hepta-4,6-diene 82 in which the cyclopropane ring blocked the 1,5-sigmatropic rearrangement and acted as a latent methylene group. Oxidation with active Mn02 afforded cyclopropyl aldehyde 83, which was condensed with the anion derived from methyl 3,3-dimethyIacryIate 97 in the presence of cadmium chloride. These conditions resulted in selective v substitution and were a consequence of isomerization to the thermodynamically most favored product This procedure was shown to be general for related systems. -- The resulting alcohol-protected triene 100 was cyclized directly to tetracyclic adduct 103 under thermal conditions in a microwave oven. Modification of the functional groups gave cyclopropyl ketone 118, which opened to the longifolene ring system by lithium/ammonia reduction. -- The route to optically active material followed a different pathway which involved the Lewis acid catalyzed addition of methanol to the optically active spirocyclopropane-cyclopentadiene 134. The product 137 was capable of rapid sigmatropic rearrangement, which in principle could give rise to several different Diels-Alder adducts. In practice, because of the constrained nature of the cyclic dienophile, the lowest energy path led to the adduct 138 with the tricyclic nucleus required for (+)-longifolene. This was the only product isolated and represented the first successful synthesis of a cycloheptane directly from a cyclopentadiene in a carbocyclic precursor. In order to complete the synthesis the lactone 138 was reduced and the primary alcohol converted selectively to its acetate 144. Sequential removal of the secondary  hydroxyl functions was accomplished under  free   radical   conditions.    Pyrolysis  of  the  acetate   146   at   525°C   provided  (+)-longifolene.

abstract: Today, organizations find themselves faced with constant change resulting in re-organization, downsizing, rightsizing, outplacement, mergers, and an ever increasing pressure to become more competitive and better able to do more with less. This has become a challenging task for leaders in many- organizations . -- Research is showing though, that some organizations are enjoying significant success. The leaders and the employees are dealing much more effectively with the onslaught of change. Many of these are what Peter Senge (1990) calls learning organizations. In these organizations there is a shared vision, teamwork, open-ness, and a deep rooted commitment to the principle of learning at all levels. -- For many other organizations such as government, steeped in the conventions of traditional bureaucracy, it appears to be an almost impractical approach to leading an organization. These large bureaucratic machines have struggled perhaps more than others, to adapt to new demands and become more change-agile. The reasons for this are numerous. This paper examines the bureaucracies, clarifies some of the challenges it faces, and outlines a set of principles and guidelines which would move an organization toward the concept of a learning organization. -- Prior to that however, a comprehensive review of the literature reveals what Senge and others are saying about the learning organization. Senge is used as a benchmark against which other opinions are explored, compared and contrasted. The five disciplines which Senge outlines are fully explored and discussed, with a view to developing a definition of the learning organization. Throughout this review, there is continuous reference to the bureaucracy and the unique problems it faces in becoming more of a learning organization. Also, as part of the literature review, the concepts of organizational learning and the learning organization are examined. This is necessary in order to develop an appreciation for the overall process of becoming a learning organization. The inter-relationship and interdependence of these concepts are discussed. Finally, as these appreciations and understandings are fully developed, a set of principles and guidelines are compiled which recapitulate the ideas and perspectives presented throughout the paper on how to move toward the concept of the learning organization.

abstract: Pinnipeds are ecologically and socially diverse, attributes that are reflected in their systems of communication. The purpose of this investigation was to document the vocal repertoire and annual cycle of vocal activity in the harp seal, a species that communicates mainly underwater, but whose social and communicative systems are poorly known. -- The study's main objectives were to describe the vocal repertoire of captive harp seals through a complete annual cycle and to document annual, seasonal and diet trends in vocal activity. Plasma testosterone in males before, during and after the breeding season were also analyzed to document relationships of testosterone concentration to vocal activity. -- The repertoire comprised 18 vocal classes, eight of which have not been described previously. Vocal activity varied seasonally and with time of day. Calls of low frequency (≤ 3 kHz) and with few harmonics (≤ 3) were predominantly used outside the breeding season, and calls of high frequency and with a high number of harmonics predominated in the breeding season. -- Levels of plasma testosterone were investigated in four captive harp seals of different ages. Concentrations varied from a minimum of ca. 0.01 ng/ml in April and May to a maximum of 9.4 ng/ml in March. Peaks in concentration occurred at the time when testes are largest in mature wild males, which is several weeks before wild females enter oestrus. Also, peaks in concentration were correlated with high rates of vocalisation. Peak levels of testosterone were lowest in the young and socially subordinate seals.

abstract: The human papovavirus JC virus (JCV) replicates only in glial cells and exhibits strict cell-specificity for expression. JC virus (JCV) has been frequently found in the plaques of brains of victims of the fatal demyelinating brain disease, progressive multifocal leukoencephalopathy (PML). PML is associated with immunodeficiency and has been identified recently as a frequent complication of acquired immunodeficiency syndrome (AIDS) . The regulatory region of JCV is contained mainly within the two 98 base pairs (bp) tandem repeats and is functional in both directions, with the early and late promoter-enhancer (JCVE and JCVL) controlling expression of large and small tumour antigens and viral structural proteins, respectively.  --  Previously, it was shown in our laboratory that the regulatory region of JCV confers glial cell-specificity to JCV and contains three potential nuclear factor 1 (NF1) motifs (Nakshatri et al. 1990a). One motif towards the late side of the genome has a 3 bp palindromic repeat and the other two located within the 98 bp repeats have 6 bp inverted palindromic sequences. --  My initial objective was to evaluate the functional role of NF1 motifs in the restricted cell-specificity of JCV. This was approached by site-directed mutagenesis of the nuclear factor 1 (NF1) motifs within the viral regulatory region. The NF1 motifs, located within the 98 bp tandem repeats which contain 6 bp perfect inverted palindromic sequences were important for glial cell-specific expression of JC virus in differentiated embryonal carcinoma cells in vivo. The NF1 site on the late side of the repeats was not important, an observation confirmed by in vitro transcription studies. These observations were correlated with in vitro DNase I footprinting and mobility shift assays, which demonstrated specific interactions of factors in glial cell nuclear extracts with NF1 sites. -- To characterize the brain-specific factor(s) inducing the expression of JCV, a cDNA encoding the factor binding to NF1 II/III located in the repeats was isolated by screening the cDNA library prepared from retinoic acid-differentiated P19 embryonal carcinoma cells by Southwestern blotting. Co- transfection of cDNA with JCVE and JCVL reporter plasmids resulted in the expression of JCV in nonglial cells such as HeLa cells. These results suggested that NF1 II/III plays a key role in the glial cell type-specificity of JCV. --  Mutations in all the three potential NF1 binding sites greatly reduced the transcriptional activity of JCV early promoter-enhancer in glial cells. However, a residual greater than basal level of activity was still observed. Examination of the JCV promoter-enhancer sequences revealed a cyclic AMP response element (CRE) motif, TGAGCTCA, 4 bp from the NF1 II/III binding site in the repeats. This increased the transcriptional activity of JCVE after treatment with the cAMP analogue dibutyryl cAMP and cyclic AMP inducer forskolin.  Mutations in CRE motifs abolished the induction of JCV expression by cAMP. In vitro binding studies showed the interaction of an approximately 43 kDa protein with CRE oligonucleotide. The results indicated an additive effect of NF1 II/III and CRE in the glial cell-specific expression of JCV.  -- JCV large T-antigen functionally transactivates the viral late promoter only in glial cells and the molecular mechanism for transactivation has remained elusive. The NF1 sequences of JCV and the amino acids of JCV T-antigen required for the transactivation have remained unclear. I performed experiments to address these issues. Using site-directed mutagenesis of NF1 sites of JCVL, the integrity of nuclear factor 1 (NF1) binding motifs in the 98 bp repeats (NF1 II/III), but not the motif external to the repeats, was found to be essential for the induction of JCVL activity by JCV T- antigen, a result which was confirmed by in vitro transcription assays. Mobility shift assays detected the increased binding of NF1 to the NF1 II/III sequences in the presence of T-antigen. This suggests that JCV T-antigen facilitates the increased binding of NF1 to NF1 II/III site, thereby activating the late promoter of JCV.  A model describing the mechanism has been proposed.  -- The region(s) of T-antigen necessary for the transactivation of JCVL was assessed with a series of constructs containing mutated coding sequences which I generated. The amino acids 196-437 region of JCV T-antigen was required for most of the transactivation of JCVL and transformation of primary baby rat kidney cells.

abstract: Considerable attention has been given to the role of Strategic Environmental Assessment (SEA) in policy, plan and program (PPP) assessment; however, there is still very little consensus on appropriate methodologies for SEA. Despite calls for SEA to develop more independently of project-level assessment, existing SEA methodologies still tend to be based on project-level EIA principles, rather than also on a trickling down of objectives of broader environmental policy. This thesis argues that if SEA is to advance in application and effectiveness then a different, but structured methodological framework is required. -- While SEA can perhaps utilize many of the existing methods and techniques from project- level assessment, the types of questions being addressed in strategic assessment are inherently different from those in project-level assessment. Accordingly, a different methodological assessment framework is required for SEA. The emphasis of strategic assessment is on the development of an appropriate strategy for action, addressing alternative courses of action, rather than the assessment of the potential impacts of a pre-determined option. In order to accomplish this, SEA methodology must be more broad brush than project-level assessment in order to allow the assessment of both the more general policy issues and the more technical plan and program issues. Similar to project-level assessment, however, a structured framework is desired in order to facilitate a more systematic and replicable assessment process. -- This thesis develops a structured, generic seven-phase assessment framework to guide SEA application. The framework is demonstrated through a case study SEA of potential Canadian energy policy alternatives. Through the use of a modified policy-type Delphi and multi-criteria analytical methods, alternative options for Canadian energy policy are evaluated and the 'best practicable environmental option' is determined. While the geographic scale of the case study and the number of participants involved is perhaps not pragmatic with respect to 'real-world' policy SEA, it does serve to demonstrate the utility of the proposed SEA framework. The emphasis of this research is on the process of strategic assessment, rather than the policy implications of the results of the case study. A number of specific recommendations for 'good-practice' SEA are presented, and key issues are raised for future SEA research.

abstract: The development of the western Newfoundland tree-ring chronologies from cross- sections collected by the Newfoundland Forest Service is the basis for this study. Sampling undertaken by the Newfoundland Forest Service started in 1985 and continued through the summer of 1997 and beyond. The data obtained from the Newfoundland Forest Service were cross-dated, time-series evaluated and standardized to achieve five ring-width indices. -- Abies balsamea is the dominant species used in the Western Newfoundland chronologies. Northern Peninsula ring widths are correlated with mean summer and winter temperatures. These ring widths are also correlated with sea-surface temperature and mean monthly surface-air temperature. The Northern Peninsula chronologies show evidence of 1820-1830s warming and subsequent cooling as well as the 1960-1970s North Atlantic anomalies. -- Comparison between published data and developed tree-ring chronologies depicts much similarity in areas from the North Atlantic sector. Comparison between temperature correlation significance in Scandinavia and the Northern Peninsula chronologies shows a definite relationship between mean monthly surface temperature for winter months and ring-width indices. -- Monthly climate data for western insular Newfoundland do not extend backward beyond the early 1930s. The development of tree-ring chronologies, extending as far back as 1760, will improve the understanding of environmental change in the Northwest Atlantic sector.

Masters thesis, Memorial University of Newfoundland.

abstract: The human breast cancer cell line MDA-468 is characterized by an overexpression of the epidermal growth factor (EGF) receptor. As a result of this overexpression, MDA-468 cells have the unique characteristic of undergoing arrest of cell cycle in G₁ when treated with pharmacological concentrations of EGF. While the ability of EGF to cause arrest of this cancer cell line is well documented, the effectors that mediate this arrest remain unknown. Since the tumour suppressor gene, p21Cipl, is a potent inhibitor of cyclin dependent kinases with a well-defined ability to confer G₁  arrest on tumour cells, it is proposed that p21Cipl may play a role in the EGF-mediated arrest of these cells. An antisense against p21cipI expression was transfected into MDA-468 cells to test this hypothesis. Single-clone cell lines were derived and examined for (i) an elimination of p21Cipl mRNA and protein, and (ii) a reduction of the ability of these cells to undergo G₁  arrest when treated with EGF. Three antisense-transfected clones demonstrated that antisense expression caused a reduction of p21Cipl with a significantly decreased capacity to undergo G₁  arrest In these cell lines an absence of p21Cipl reduced the ability of EGF-treatment to cause growth arrest This correlation may indicate that p21Cipl is an important player in the EGF-mediated growth arrest of MDA-468 cells.

Masters thesis, Memorial University of Newfoundland.

abstract: The purpose of this paper folio is to provide a resource for educators to combat bullying in their schools. Dealing with bullying can be very frustrating. Learning that there are effective preventative measures and interventions that can be applied to counter bullying is extremely encouraging. -- Understanding the complexities of bullying is a first step in beginning the fight. It is important for educators to understand the bully's view of the world as well as the victim's perspective so that they can in turn attempt to tackle the problem. Research also suggests that establishing an anti-bullying policy is essential to bullying prevention and intervention. An understanding of the policy development process is critical in establishing a successful policy that will endure. Central to the literature on policy development is the necessity to involve all stakeholders.  But policies cannot exist in isolation. Policies must become an integral part of the school culture. Nurturing an anti-bullying culture can be achieved in a variety of ways such as through the physical environment, a cooperative curriculum, the peer group, teacher interventions and community involvement. Schools have an important role to play in taking up the challenge of tackling bullying.

abstract: This study will examine the activities and philosophies of the Woman's Peace Party of New York/Woman's International League during the period of the formation of a distinct women's peace movement in the United States, 1914-1919. Inspired by the belief that women shared a unique perspective on issues of peace, war and militarism, the Woman's Peace Party of New York organized and participated in many of the ground-breaking United States peace, antimilitarist and free speech/civil liberties activities of the World War I period. One of the few peace organizations which managed to continue to function as a critical voice towards war and militarism during 1914-1919, this study aims to reveal how and why their protest against the system of war and militarism developed into a challenge to the economic and gender power structures of their society. Specifically, the party's broad definition of peace, strong affiliations with other peace and antimilitarist organizations, and versatile conception of gender as both distinct and equal led party members to articulate the connections between sexism and militarism in seeking the route to freedom for women and lasting peace.

abstract: In this thesis a system of lexical aspects, or Aktionsarten, is considered from the point of view of Guillaumian Psychomechanics, which is a form of cognitive linguistics. Guillaume proposes that verbal systems have developmental stages, the total system of stages being called the chronogenesis, that is the development of the time image. We have proposed the existence of pre-chronogenetic levels, which concern the development of the event image of the lexeme, which in Guillaumian terms concerns the ideogenesis (choice and development of lexical notion) rather than the morphogenesis (development of the grammatical notion). The development of the event image is viewed as comprising five successive stages at the pre-chronogenetic level, each of them rooted in perception. -- At the first stage the perceiving subject and the perceived event are separated in consciousness which results in the realisation of the cognitive feature 'Occurrence'. This feature is presumed to have a linguistic representation of the Inherent lexical aspect, i.e. the basic meaning which unites words of different parts of speech (e.g. shoot, shot) and serves to lexically identify the same kind of event. -- The second stage comprises the realisation of staticity and movement, or change. The cognitive features Stasis and Kinesis of the event correspond to the linguistic categories of Stative and Non-Stative lexical aspects. -- The third stage is based on the preceding notion of movement, developing the realisation of two kinds of movement - determinate, proceeding in a definite direction and thus bound to reach its end-point, and indeterminate, unorderly movement. The linguistic exponents of these cognitive notions are the determinate and Indeterminate lexical aspects. -- The fourth stage is based on the notion of orderly movement which is goal oriented and proceeds from a beginning through a unidirectional process to an end. The binary tensor provides the remaining two features of this level - punctual and repetitive occurrence. These cognitive realizations of the manner of occurrence correspond to the Punctual and Iterative lexical aspects. -- The final stage involves the separation of the event and its subject, or pivot, which allows for the subject to be viewed either externally, corresponding to the Perfective lexical aspect, or internally, corresponding to the Imperfective lexical aspect. The hierarchical system of lexical aspects is subsequently provided. -- The second part of the thesis is an application of the proposed theoretical constructs for the analysis of the aspectual subsystems of Russian.

The retrospective exploratory research was conducted with 32 juvenile sexual offenders who had been sentenced to secure custody at the Newfoundland and Labrador Youth Centre in Whitbourne. Each of these offenders, while in custody, had completed varying degrees of a treatment program, entitled 'Healthy Lifestyles. The program was led by facility therapists between April 1994 and October 1997. There were three groups. Group 1 completed the program, group 2 was not offered the program, and group 3 completed the educational component ofthe program. The study investigated both sexual and nonsexual recidivism of the three groups. It explored factors such as prior convictions, typology, sex of victim, and post release follow-up period. It also investigated a single case of juvenile sexual recidivism. The findings suggested that the educational component of the treatment program was effective in reducing both sexual and nonsexual recidivism. The nonsexual recidivism rate of offenders, who completed the educational component of the program, was much lower than the recidivism rate of the group of juveniles who were not exposed to any of the treatment components. There was a positive correlation between follow-up period and nonsexual recidivism. Juveniles who were not exposed to any of the treatment programs were more likely to re-offend as the follow-up period increased.

Masters thesis, Memorial University of Newfoundland.

abstract: Alkanolamines are an industrially important class of compounds that are used in a wide variety of applications because of their thermal stability, volatility, and basicity. Since they are ideal for probing solvation behavior in high temperature water, they are of considerable interest in the development of theoretical models for ionic solvation. Standard partial molar volumes V°, heat capacities C°p, and compressibilities K°are important in this context because they define the temperature and pressure dependence of important parameters such as the ionization constant. This comprehensive study presents thermodynamic data leading to standard partial molar properties and excess properties of the tertiary alkanolamine, methylchethanolamine (MDEA) and its chloride salt over a wide temperature range at various pressures. -- Apparent molar volumes of aqueous methyldiethanolamine and its salt were determined with platinum vibrating tube densitometers over a range of temperatures from 283 to 573 K and at pressures from 0.1 MPa to 20 MPa. Apparent molar heat capacities were obtained using a Sodev Picker flow microcalorimeter at a pressure of 0.1 MPa and within the temperature range of 283 to 328 K. The experimental results for the neutral amine were well represented using linear expressions with corrections for partial ionization and then extrapolated to infinite dilution to obtain values for V° and C°. The experimental results for the salt were determined as a function of ionic strength and analyzed by means of the Guggenheim form of the extended Debye-Hiickel equation to obtain values for V° and C°p. Apparent molar isothermal compressibilities kt° at a pressure of 0.1 MPa were obtained at temperatures from 283 to 313 K with speed of sound measurements. Compressibilities were important in this study since they account for the small pressure dependence observed in the measured apparent molar volumes. -- The standard partial molar volumes V° for the neutral amine and its ionized form show increasingly positive and negative values at high temperatures and pressures, as predicted by corresponding states and group additivity arguments. The standard partial molar volume data were used to successfully extrapolate low temperature C°p data to elevated temperatures. The density model and the revised Helgeson-Kirkham-Flowers (HKF) model have been used to represent the temperature and pressure dependence of the standard partial molar properties to yield a full thermodynamic description of the systems. Further, using appropriate expressions, the density model was employed to obtain the concentration dependence of the apparent molar properties. -- Excess heat capacities CpEX from 278 to 373 K were determined with a CSC 4100 differential scanning calorimeter over the entire mole fraction range for the water- methyldiethanolamine system and the results were analyzed using Redlich-Kister type equations. Calculations were made in accordance with appropriate water vapor corrections based on Raoult's law and the Clausius-Clapeyron equation. The excess heat capacities are positive in magnitude over the entire mole fraction range which is typical of completely miscible water + polar organic systems and indicates a large positive deviation from ideality. In general, the CpEX become progressively more positive as the temperature increases with the maxima shifting to larger mole fractions in the water-rich region. Direct data reduction yields reduced excess heat capacities which appear to be consistent with solute-induced structural changes in the intermolecular structure of the water/MDEA system.

abstract: The electronic band spectra of the neutral molecule 12C16O, its isotopomers 13C16O, 12C18O, and 13C18O, and the molecular ion 12C16O+ are of considerable importance in astrophysics and atmospheric physics. The rotational emission spectra of these molecules are routinely used in millimeter radio astronomy to map the molecular densities in the interstellar medium. These molecules are present in circumstellar envelopes, and cometary and planetary atmospheres. The molecular ion CO+ has applications in the study of radiative heating of hypersonic space craft at escape velocity and in the atmospheric fringe of Venus. – The vacuum ultraviolet spectra of the fourth positive (A 1Π – X 1Σ+) system of carbon monoxide isotopomers 12C18O and 13C18O excited in the anode column of a hollow-cathode discharge tube, and of the isotopomers 13C16O and 13C18O generated in emission in a jet discharge apparatus were photographed in the spectral region 1370 – 1935 Å on a 10.6 m vacuum grating spectrograph. Detailed rotational analysis for thirty nine bands of the three isotopomers of the A-X system has been carried out. Several perturbations occurring in the A 1Π state due to its neighbouring states e 3Σ-, a´ 3Σ+, d 3Δi, I 1Σ-, and D 1Δ were observed. From a deperturbation analysis, the deperturbed molecular constants, were obtained for the A 1Π state as well as for the perturbing states of the three isotopomers. Perturbing parameters and mixing coefficients which characterize perturbations were also derived. – Using the experimental data of the fourth positive system of the three isotopomers, the term values of the A 1Π, v=0 to 9 levels of 13C16O, v=1 and 2 levels of 12C18O, and v=1 level of 13C18O were determined. The term values of the Rydberg states B 1Σ+, v=0 and 1, C 1Σ+, and E 1Π, v=0 were calculated for the isotopomers 12C18O and 13C18O, by combining the present data and those of the B 1Σ+ - A 1Π, C 1Σ+ - A 1Π, and E 1Π – A 1Π systems taken from the literature. The molecular constants of Rydberg states B, C, and E were determined from the calculated term values. – The comet-tail (A 2Πi – X 2Σ+) system of 12C16O+ occurring in the cathode glow of a hollow cathode discharge tube and photographed in the spectral range 3345 – 8500 Å at high resolution was reinvestigated. Spin-splitting of the rotational levels of all the analyzed ten bands was observed. The observed intensity distribution of the branches is in good agreement with theoretical calculations. Rotational constants were obtained for the A 2Πi and X 2Σ+ states from a global fit of the present data of the comet-tail system and the infrared and microwave data available from the literature.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: The Northwest Atlantic ecosystem is currently undergoing changes in species interactions and ocean climate. Capelin (Mallotus villosus ), the dominant forage fish in the ecosystem, is the main prey item of marine birds, mammals and piscivorous fish. In the 1990s, spawning capelin were small, spawned later, shifted their distribution southerly to non-traditional areas compared to historical accounts, and abundance estimates have varied widely. During these changes and divergent biomass estimates, this research was initiated. The focus of this thesis is the multi-scale behavioural interactions of marine predators and prey: a marine diving bird, the common murre ( Uria aalge ), and its main prey species, capelin. This study integrates both colony-based and vessel-based techniques. I showed that some aggregations of capelin are stable in space and time on a number of scales: fine- (1-100 m; minute-hour), coarse- (1-100 km; day-week) meso-scale (100-1000 km; annual), allowing murres to use memory to locate prey at sea during different periods during their annual cycle. Social foraging techniques appeared to be important on fine- and coarse-scales (local enhancement, network foraging) while no evidence was found for social foraging techniques over larger spatial scales (Information Center Hypothesis). Spatial scales at which murres tracked capelin were highly variable, as found in other studies examining predator-prey interactions of mobile organisms. The tracking scales of murres to capelin were smallest during the breeding (0.8-5.1 km) and pre-breeding periods (3.1-8 km), compared to post-breeding (6.0-50.0 km). This variability in spatial associations between predators and their prey was likely due to different energetic requirements, locomotory constraints and search strategies used among these periods. Inter-colony comparisons of provisioning behaviour by murres revealed low feeding rates of chicks at the largest murre colony in eastern Canada relative to a smaller colony, which resulted in the lowest average mass and condition of fledgling murres (191.6 ± 4.0 g) reported in the literature. Density-dependence, both while foraging at sea and rearing chicks at the colony, and prey distribution around the largest colony resulted in additional provisioning constraints relative to a smaller colony and divergent life history strategies at the two colonies. Poorer chick condition, and presumably lower recruitment, may have resulted in a lack of population growth at the larger colony, which contains 85% of the common murres in the Northwest Atlantic. Clearly, common murres interact with their prey over multiple temporal and spatial scales and these behavioural interactions are manifested in demographic parameters.

abstract: Nitrilotriacetic acid  (NTA),  N(CH2CO2H), has been the subject of considerable research and public interest  over the past few years. The need to predict the environmental impact of NTA became necessary when this chemical was prepared as a replacement  for polyphosphates in household detergents and this instigated the bulk of recent research on this Compound.  A summary of this research,  given in the Introduction Section of this thesis,  shows that little work had been done in studying the effect NTA might have on the marine environment. -- Our contribution to this area of research includes the development of a gas chromatographic method of analysis capable of determining NTA below the ppm level in seawater. This method should facilitate further studies of NTA in seawater.  The analytical procedure developed was then put to use in a study of the biodegradability of NTA in seawater which is also described in this thesis

abstract: The objective of this study was to concentrate polyunsaturated fatty acids (PUFA) from seal blubber oil and to investigate the use of lipases as catalysts for synthesizing acylglycerols from glycerol and polyunsaturated fatty acid concentrates. Additionally, the study of the oxidative stability of acylglycerols synthesized by lipases was intended. Urea complexation was used to concentrate polyunsaturated fatty acids from seal blubber oil. The concentration of docosapentaenoic acid in final products reached as high as 24%. Enzymatic synthesis of acyglycerols directly from glycerol and fatty acid concentrates in organic solvents was studied. Three lipases (Lipase SP435 from Candida Antactica, lipase IM60 from Mucor miehei, lipase PS30 from Pseudomonas sp.) were used as biocatalysts for esterification. Lipase SP435 from Candida Antarctica showed the highest activity for esterification. Effects of reaction parameters, namely temperature, time course and mole ratio of glycerol to fatty acids were followed with all three lipases. The optimal reaction time was 24 h at 30 °C and the mole ratio of glycerol to fatty acid was 14 for lipase SP435. The maximum degree of acylglycerol synthesis exceeded 90%. The effect of time course and mole ratio of glycerol to fatty acids on acylglycerols distribution was also determined. The proportion of monoacylglycerols in samples was low and remained almost constant as the reaction proceeded. However, the proportion of diacylglycerol was increased rapidly in a short time period and then decreased gradually to some extent, depending on the lipase, and then plateaued. The proportion of triacylglycerol was increased gradually to some extent depending on the lipase, than it was maintained constant.   The effect of mole ratio of glycerol to fatty acids on the acylglycerols distribution was studied. The higher mole ratio of glycerol to fatty acids, the higher was the proportion of monoacylglycerols and the lower the proportion of triacylglycerols. The oxidative stability of different samples was tested under Schaal- oven conditions. Progression of oxidation was monitored by determination of conjugated dienes (CD), propanal content and TBARS (thiobarbituric acid reactive substances) values. In this study, three samples were used - original seal blubber oil, and concentrate of fatty acid esters and triacylglycerols synthesized by lipase SP435. The results demonstrated that the oxidative stability of synthesized acylglycerols was superior to that of the fatty acid esters. At the beginning, the CD and TBARS values of the three samples were similar. However, fatty acid esters gave rise to higher CD and TBARS values compared to the other two samples as oxidation reaction proceeded.

Masters thesis, Memorial University of Newfoundland.

abstract: To better understand the cycling of carbon in a cold ocean coastal environment, molecular distributions and stable carbon isotopic compositions of various aliphatic and poly cyclic aromatic hydrocarbons (PAH) have been determined for marine sediments of Trinity Bay, Newfoundland. Sediments were collected in the form of grab and core samples from the Northwest and Southwest Arms, extending into Trinity Bay. High levels of sulfur in the sediments required an exhaustive procedure for the complete removal sulfur interferences in chromatography. Separation of aliphatic hydrocarbons from PAH was accomplished through alumina/silica column chromatography. The combination of molecular characterization by gas chromatography mass spectrometry (GCMS) and isotopic fingerprinting through gas chromatography combustionisotope ratio mass spectrometry (GC/CIRMS) enabled the distinction between marine, terrestrial. and anthropogenic sources of some of the hydrocarbons. -- Aliphatic hydrocarbon results indicate large biogenic influences from marine sources, with particular evidence being the abundance of C25 highly branched isoprenoid alkenes. It is believed that these compounds are produced by certain diatoms immediately preceding the spring diatom bloom. The molecular distributions and carbon isotopic compositions of /z-alkanes can be attributed to contributions from mari The concentration levels of PAH in most sediment samples are extremely low, revealing that the marine environment in this area is relatively pristine. The distribution patterns and isotopic results of PAH present indicate source inputs from combustion, most likely due to wood-burning, with minor contributions from petroleum sources.ne and terrestrial sources with slight mixing of anthropogenic petroleum sources.

abstract: Switching is one of the bottlenecks restraining the efforts of researchers toward implementing broadband communication systems. In this dissertation, we provide a comprehensive study of a promising switching architecture called the Balanced Gamma (BG) network. The BG network has shown good performance in terms of throughput, average cell delay, and reliability, and has displayed potential for application in broadband communications switch fabrics. -- Designing highly reliable systems is a crucial requirement in the industry of broadband communications where consequences of the system failures are very expensive. Accordingly, we provide an exact model for network reliability of the BG network. The model demonstrates that the network is highly reliable and can be confidently deployed in communication systems. -- The performance of the network is further investigated under different payloads containing uniform and non-uniform traffic. Uniform random and bursty are the traffic types used. Several simulation experiments are carried out to measure the ceil loss, cell average delay, and buffering requirements of the BG network. In addition, we pursue an analytical model under uniform random traffic to verify our simulation results. The performance of the network is compared with both an ideal nonblocking network and the crossbar network. It is determined that the network has much better behavior than the crossbar switch and operates very closely to the ideal architecture under most types of offered traffic loads. -- Finally, we introduce a VLSI design for the BG network using 0.35 CMOS technology supported by the Canadian Microelectronics Corporation. The design has mainly three components, the switching element, the output port, and the network main controller. The design features built-in self-test (BIST) which has become an essential part of any fast digital system. We also parametrize the design such that the amount of effort needed to generate a fabric with arbitrary size is minimal. We describe the design in the Very High Speed Integrated Circuit Description Language (VHDL).

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Many epidemiological and experimental studies have strongly implicated human papillomavirus type 16 (IIPV-16) in cervical neoplasia. The oncogenic potential of this virus can be demonstrated by transformation of primary baby rat kidney (BRK) cells by cotransfection of the viral genome with the activated EJ-ras oncogene. I performed a mutational analysis of the viral genome to map the regions essential for its transforming activity. For the SV40-bascd early region expression plasmids, the disruption of the E6, E2, E5 and the 3' region of the El open reading frames (ORFs) did not affect the transforming activity of mutated plasmids, whereas the insertion of translation termination linkers within the E7 ORE abolished transformation. Additional sequences present in the 3'-flanking region of the E7 ORF were also required for efficient transformation. -- The 3' flanking region sequences were analyzed in detail in SV40-based E7 expression plasmids by progressive deletion analysis and site-directed mutagenesis. Disruption of the nucleotide (nt) 880 splice donor site within this 3'-flanking region abolished transformation. Regeneration of the wild- type sequence in a previously transformation incompetent splice site mutant restored transformation. Mutating the wild-type splice donor site to the consensus splice site resulted in higher levels of transformation, whereas mutating the + 2 position of the consensus sequence significantly reduced the frequency of transformation. It was shown with RNase protection assays that the transformation-deficient splice site mutants accumulated lower levels of E7 RNA, primarily because of rapid destabilization of E7 RNA. -- The splice sites present within the E6 ORF were examined for their ability to substitute for the loss of nt 880 splice donor site function. The wild-type E6 splice sites, as well as the heterologous splice sites of the SV40 intron, were able to partially substitute for the nt 880 splice site function. These results indicated that the efficient accumulation of HPV-16 E7 RNA and transformation of BRK cells depend on the presence of an intron in the transcription unit. -- Recent studies have indicated the presence of naturally occurring HPV-16 antisense (AS) RNA in cervical carcinomas. I have detected AS E7 and E7/E1 RNA in Cos-1 cells transiently transfected with SV40-based HPV-16 early region expression plasmids. By deletion mutation analysis, the AS promoter was localized to nt 4031-4338 of HPV-16. Primer extension analysis and RNase protection assays indicated that the AS RNA was initiated from multiple sites in an AT-rich region around nt 4100. The AS promoter was active when cloned downstream of the chloramphenicol acetyl transferase (Cat) gene, giving rise to AS Cat RNA. -- AS E7 RNA was detected in both the nucleus and cytoplasm. The AS RNA formed a duplex with the sense (S) E7 RNA. The presence of AS RNA was correlated with reduced splicing of E7 RNA from the nt 880 splice site and the synthesis of E7 protein.
