abstract: The acute blockade of spinal glycinergic inhibition with intrathecal strychnine (i.t. STR; a glycine antagonist) in rats produces a change in somatosensory processing which resembles allodynia, a symptom of clinical neural injury pain. In the present study, the effects of i.t. STR were examined in urethane-anesthetized rats. Noxious paw pinch (PP) , or tail immersion (TI) in 55°C water, evoked a pronounced pressor response, tachycardia, a motor withdrawal reflex and de synchronization of the electroencephalogram (EEG) . Non-noxious, hair deflection (HD) , applied to the back, flanks, legs and tail of the rat, elicited only minor cardiovascular responses. Following i.t. STR (40 μg) , an identical HD stimulus evoked responses resembling those seen with noxious stimuli: an increase in mean arterial blood pressure (M.A.P) , tachycardia and a motor withdrawal reflex. All manifestations of this HD-evoked, STR-dependent allodynia were: 1) observed only with a light plane of anesthesia (as determined by EEG), 2) reversible with time (within 15-30 minutes) , 3) observed without convulsions, 4) evoked only when HD was applied to cutaneous dermatomes with innervation from spinal segments near the i.t. STR injection site (segmental), and 5) i.t STR dose-dependent (10-50 μg) . I.t. glycine produced dose-dependent inhibition of all indices of STR-dependent allodynia with ED₅₀ and 95% C.I. values of 609(429-865), 694(548-878) and 549 (458-658) μg for inhibition of heart rate (HR) increases, M.A.P. increases and motor withdrawal reflexes, respectively. I.t. betaine (a glycine derivative) also dose-dependently inhibited STR-dependent allodynia, possibly through metabolism to glycine. The ED₅₀ and 95% C.I. values were 981(509-1889), 1045(740-1476) and 1083(843-1391) μg for inhibition of HR, M.A.P. and motor withdrawal responses, respectively. EEG synchrony was unaffected by i.t. glycine or i.t. betaine. Neonatal capsaicin (25 mg/kg, s.c, post-natal day (PND) 1, and 50 mg/kg, s.c, PND 2, 3, 4, 11, 25, 55 and 85) significantly attenuated responses evoked by mechanical (PP), thermal (TI) or chemical (topical xylene) noxious stimuli, but did not affect STR-dependent allodynia. All indices of STR-dependent allodynia were also unaffected by i.t. morphine at a dose (50 μg, i.t.) which completely abolished responses evoked by noxious TI or PP. STR-dependent allodynia was dose-dependently suppressed by i.t. γ-D-glutamylglycine (DGG; nonselective excitatory amino acid [EAA] antagonist) and i.t. 2,3 -dihychroxy-6-nitro-7-sulf amoyl-benzo (f) quinoxaline (NBQX, AMPA receptor antagonist). The ED₅₀'s and 95% C.I. values for DGG against HD-evoked, STR-dependent HR, M.A.P. and motor responses were 15.6 (11.3-21.6), 16.9 (11.7-24.3) and 8.1 (5.2-12.5) μg, respectively. The corresponding values for NBQX were 12.2 (6.8-21.8), 14.4 (8.6-24.0) and 10.4 (5.5- 19.6) μg. EEG synchrony was unaffected by i.t. DGG or i.t. NBQX. The results of the present study indicate that glycine plays an important role in the spinal modulation of  non-nociceptive input and supports the hypothesis that a loss of glycinergic modulation may underlie allodynia. The failure of i.t. morphine and neonatal capsaicin to prevent STR-dependent allodynia indicates that this phenomenon is initiated by primary afferent neurons not normally involved in nociception, presumably Αβ-fibers. The sensitivity of STR-dependent allodynia to both NMDA and non-NMDA receptor antagonists, and the failure of i.t. STR to produce hyperalgesia to mechanical, thermal or chemical noxious stimuli, confirm the independence of nociceptive pathways and STR-sensitive input in this model. The i.t. STR model allows the investigation of an important symptom of neural injury pain (opioid-resistant allodynia) in anesthetized animals, without having to inflict injury or to expose a conscious animal to aversive painful conditions, and might provide a useful alternative to chronic conscious animal models of allodynia.

abstract: This thesis reviews the research on Phonemic Awareness and Inservice Training Programs and culminates in the development of an Inservice Program on Phonemic Awareness. The research on phonemic awareness reviewed studies dealing with the correlation between phonemic awareness and reading, the predictive ability of phonemic awareness on reading ability, the effect of training in phonemic awareness skills on reading achievement and the levels of phonemic awareness. The research on inservice training programs reviewed studies dealing with different types of inservice programs, characteristics of effective inservice programs, and some models of staff development. -- An inservice training program was developed for teachers and early childhood educators. The inservice is comprised of four two-hour sessions, designed to be presented over a period of three months. The inservice participants are required to read supplemental articles between sessions, observe their peers using the strategies discussed in the training sessions either in person or through videotape , and administer an assessment to their students both before and at the end of the inservice. The facilitator is required to provide videotapes of several of the activities being used with children and is encouraged to provide examples of some of the activities to show the participants. Definitions and theoretical background are provided for both the facilitator and the participants. An evaluation of the inservice is provided for the participants to complete at the end of the inservice training program.

abstract: In the last decade, waterjet propulsors have found increasing acceptance as an alternative to marine screws and other propeller types. Over the same interval, waterjets have evolved from relatively small, simple propulsors for small recreational craft, to sophisticated engineering systems appropriate for high speed and high power vessels. The continuing development of propulsors for such vessels is aided by research for improvement and evaluation of designs. The development of research capabilities in this field is in progress at the Institute for Marine Dynamics. It has been focusing on the ability to perform experiments of vessels and their propulsors at model scale in order to evaluate the performance of the integrated system. -- Model testing techniques for waterjet propelled craft are reviewed and discussed from various relevant works on the subject. Several types of waterjet propulsors as well as some of the common vessel types are identified with respect to the scope of the testing capabilities of the facility. Two phases of experiments were prepared for a model of a 12 metre recreational craft with simple model jets. The phases consisted of bare hull resistance tests and self-propulsion tests. The experiments were intended as trials for testing techniques and instrumentation since results could be compared with the full scale performance of the vessel. One conclusion drawn from the tests was that a model waterjet propulsor would have to be designed and instrumented specifically for such experiments. -- An experimental waterjet propulsor test platform was then developed to accommodate the requirements derived from the initial test phases. The platform housed a model which employed a modular design allowing variation of internal geometry of the waterjet design if required. The platform was fully instrumented to measure flow speeds and pressures in the nozzle and near the impeller. A transparent impeller region was designed to observe possible cavitation phenomena. Thrust, torque, shaft speed and volume flow rate were also measured. The design, instrumentation, test program and test results of the model waterjet and platform are presented and discussed.

Masters thesis, Memorial University of Newfoundland.

abstract: The Newfoundland and Labrador Department of Education (1996) has issued policy documents to all schools, emphasizing collaboration in the delivery of services to students in the province. Educators are expected to implement collaborative practices in this delivery of services. In the absence of any direction within the policy documents, this paper addresses the educator's role when collaborating with school personnel.  A brief history of collaboration within organizational structures is presented in order to interpret the current trend toward collaborative practices in school systems. A review of the literature clarifies the skills and the principles of collaboration within the context of consultation, team structures, and school reform initiatives. This paper provides educators with the information they require in order to enact collaborative practices, as outlined in government policy documents.

abstract: Kuwajima et al. reported that the Lewis acid-catalysed reaction of a ketal with 1,2-bis(trimethylsilyloxy)cyclobutene (1) followed by rearrangement of the resulting cyclobutanone derivative with trifluoroacetic acid can provide a 2,2-disubstituted 1,3-cyclopentanedione in a reasonable yield. White this transformation has been improved by several groups, we now report, contrary to the literature, the analogous reaction between ketones and 1 occurs. For many substrates addition of a small amount of water to the reaction medium after completion of the first step assisted the subsequent rearrangement to the product, such that reversion of the intermediate to the starting ketone became an insignificant process. Yields were best with cyclohexanones (>90%), but steric hindrance and the presence of conjugated double bonds reduced yields considerably. This new spiro-annulation procedure has been applied to model studies towards the syntheses of fredericamycin A and a [4.3.3]-propellane. -- Model studies towards fredericamycin A began with 1-indanone. Geminal acylation with 1 followed by dehydrogenation provided the key enedione, spiro[3-cyclopentene-1,r-indan]-2,5-dione (83), which had established the key spiro center required for fredericamycin A. Our efforts concentrated on the condensation of 83 with 5,7-dimethoxy-1 (3H)~ isobenzofuranone (143). In an alternative approach, a Diels-Alder cyclization between the xylylene precursor, 3,4-bis(dibromomethyl)-1-methoxybenzene (114) and 83 was developed. -- Our studies towards the synthesis of propellanes was based on a novei intramolecular geminal acylation of a bis(trimethylsilyloxy)- cyclononene moiety (175). We had hoped that 175 could be prepared from diethyl 5-(1\3'-dioxocyclopentane)-4-methyl-1,9-nonanedioate (174), however geminal acylation of diethyl 4-methyl-5-(1,3-dioxolan-2- yl)nonanedioate (173) with 1 provided 174 in only trace amounts. As reported from our studies on the geminal acylation of ketals and ketones with  1 we attributed this lack of reactivity to the methyl substituent. Our second approach concentrated on a symmetrical bis(trimethylsilyloxy)- nonene compound. Double Grignard addition of the organomagnesium compound derived from 5-bromo-1-pentene to an ester gave 1,10- undecadien-6-ol (177), which established the carbon skeleton required for the nonene structure. Oxidation to 1,10-undecadien-6-one (179), followed by geminal acylation with 1 afforded 2,2-bis(4'- pentenyl)cyclopentane-1,3-dione (181). Conversion of the terminal double bonds of 181 into esters gave the nonene precursor, dimethyl 5-(1',3'- dioxocyclopentane)nonane-1,9-dioate (185). Unfortunately, our attempts to effect the acyloin condensation (diester 18£i to nonene species) and the subsequent intramolecular geminal acylation were not successful.

abstract: The purpose of this Major Report is to address the issue of gender in relation to the fishery crisis and two of the largest federal government adjustment programs (NC ARP and TAGS) designed and implemented to meet the needs of those left unemployed in the fishing industry. The working hypothesis of this Major Report is that NCARP and TAGS neglected to meet adequately the needs of women working in the processing sector of the fishery due, in large part, to a lack of attention to previous research and experience on the part of those responsible for designing and implementing these adjustment programs. -- One of the most important findings of this research is what it revealed about the lack of coordination of efforts of the federal and provincial government departments responsible for responding to the crisis. In particular, these programs have not adequately addressed the needs of women working in the processing sector of the fishery. Arguably, it is very much in the public interest that the failure of the adjustment programs and their differential impact on men and women be fully understood. It is one of the recommendations of this report that such research be carried out.

Masters thesis, Memorial University of Newfoundland.

abstract: The decade of the nineties has been one of change in the province of Newfoundland and Labrador, a change which has permeated the entire socio-economic fabric. Within this context the educational system has attempted to adjust accordingly to provide programs which would enable graduates of provincial schools to be competent and competitive in the global realities of our province. -- One of the more notable changes has been the move to provide courses of study which are global in nature, either by offering global studies, inserting units with a global focus, or infusing existing curricula with global elements. This change serves to enhance the literature component of the English language arts curriculum as literature is especially well suited to the infusing of a global perspective. The global orientation of the Atlantic provinces' senior high English language arts curriculum is notable in terms of its philosophy, stated curriculum outcomes, and program design. -- Yet, simultaneously, the English language arts curriculum has a utilitarian focus in which emphasis is placed upon promoting information technology in response to the perceived importance of technology in the society of the twenty-first century. The end result is a potential threat to the study of literature as the technologies may be given greater emphasis while literature is used only for its utilitarian worth of promoting literacy among students. This, too, is evident in the philosophy, curriculum outcomes, and program design. -- The eclectic nature of the English language arts curriculum provides an interesting study of how differing perspectives help determine the emphasis of the curriculum. However the senior high English language arts program is interpreted, the current design of the curriculum is a marked shift in focus from traditional perspectives of literature study, a factor which will impact dramatically upon how students in the secondary schools of Newfoundland and Labrador experience literature.

abstract: It is a constant challenge for kindergarten teachers to create learning experiences and find materials to meet curriculum objectives, in addition to their other daily duties. Therefore, I have developed a thematic unit for kindergarten, which stresses early literacy and integrates all the subject areas. -- The unit, Going Places, explores the social studies topics of transportation and safety. This curriculum package includes a theoretical framework on the functions or uses of language and discourses on early literacy and how the kindergarten child learns, as well as detailed objectives, lesson plans, resource lists and documented copies of resources, to implement a month-long thematic unit. -- Going Places is based on a functional communications perspective for learning language. The theoretical information comes primarily from Allen, Brown and Yatvin's (1986) book, Learning Language Through Communication: A Functional Perspective. Much of the theory included here can be credited to Michael Halliday (1969, 1975, 1994) and others such as Frank Smith (1977). The communicative functions emphasized are the informative, affective, imaginative, ritualistic and persuasive functions. The research component outlines the functional perspective and the unit, Going Places, is built around this perspective or framework.

abstract: This study explores Grade 4 students' perceptions of themselves as readers and what factors influenced these perceptions. Grade 4 students, consisting of nine females and eight males were observed in their natural classroom setting over a seven-week period. Multiple data collection methodologies included formal and semi-formal interviews, observations, written self-assessments, a parent questionnaire, informal interviews with former teachers, and school records/data. The constant comparative method of data analysis was utilized. -- The Grade 4 students viewed themselves as good readers. They view reading as decoding and stated that daily practice would improve their reading. The factors, which emerged as having influenced their perceptions of themselves as readers, are presented in five main categories of A) Decoding, B) Perceptions, C) Reading Affect, D) Value of Reading and E) Physical Characteristics of Print/Books. -- The findings have implications for educators in the classroom. Prior to creating a classroom atmosphere and classroom instruction to best meet the needs of the students, it is necessary to understand the student's perception of him/herself as a reader and the factors which influence this perception.

abstract: This thesis represents a historical-comparative analysis of two major types of grammatical aspect.  The morphological means of expressing aspect in Ancient Greek and Latin, inherited from late PIE, is compared with the grammaticalized Aktionsart, i.e. lexical aspect, of Ancient Slavic. The verb systems of Ancient Greek and Latin are analyzed with reference to the origin and development of verb category functions from late PIE. Grammatical aspectual functions, which are morphologically expressed in Ancient Greek and Latin, are contrasted with Aktionsart or lexical aspectual functions. Interrelations between tense and aspect within the verb system established by the Cognitive-Functional analysis represent a diagnostic criterion in distinguishing grammatical from lexical aspectual functions. -- The verb system of Ancient Slavic undergoes a major change of grammaticalizing Aktionsart. One of the major goals of this thesis is to determine the causal factors for this recategorization of giammatical aspectual function. Grammaticalization of Aktionsart also carries a number of consequences for certain grammatical formations of modem Slavic languages to be examined. -- The choice of these three languages is related to a major theme of this thesis, i.e. to represent two types of grammatical aspectual functions and to explain grammaticalization change from morphological to lexical aspect.   Ancient Greek and Latin are chosen as examples of the old Indo-European languages that preserve late PIE morphological means of expressing aspect. Specifically, the verb system of Ancient Greek resembles that of late PIE, while Latin underwent major restructuring of the verb system from a three-way to a two-way aspectual contrast among verb categories. Ancient Slavic is chosen to exemplify and explain grammaticalization of Aktionsart which represents a change from the inherited to a new type of grammatical aspect. The choice of Ancient Slavic is also related to typological similarity of a three-way aspectual contrast with that in Ancient Greek.

abstract: A major problem plaguing programmable robot-based assembly systems today is the lack of communication between robot programming and assembly planning. Whereas a robot learns to perform assembly tasks through programming, it assembles mechanical parts into a product by following the assembly sequence determined by planning. Robot programming and assembly planning have been dealt with mostly as two separate research topics. Nevertheless, the internal representation of parts and their topological and geometrical relationship required by planning could be automatically synthesized from the information obtained in programming. This observation becomes a view in advanced assembly automation systems that integrate robot programming and assembly planning for better performance and higher efficiency. -- This thesis addresses the issues of graphical integration of the robot programming process and the sequence planning process for mechanical assembly. It treats the robotic assembly sequencing as a motion-planning problem with special constraints. During the programming phase, the order of effective assembly actions is built once a robot effectively performs an assembly task. As a result, the information of an assembly scene and ordered robotic actions can be produced and stored. In the unified system presented in the thesis, the sequence planning process directly retrieves this information for automatic and fast planning. Since analyzing ordered robotic actions and executing partial geometric checks are usually much fast than performing full geometric checks, this integrated approach offers significant computational advantages in comparison with other 'full-automatic' planning approaches. In addition, the approach feeds all the feasible sequences generated from the planning process to the programming process, and provides the 'automatic re-programming' feature to the programming process. As a link between the programming and planning processes, this integrated approach presents a richer form of communication between them, which is necessary to efficiently solve real-world robot-based automation problem. The validity of this approach is justified with a prototype system, namely INTEG. Experimental results are also given in the thesis that include examples varying from simple to complex assembly tasks.

abstract: The fate of spring phytoplankton production at subzero temperatures in Conception Bay, Newfoundland, was traced using chloropigments as biomarkers of phytoplankton biomass and flux, and as indicators of biological processes. The study included conventional fluorometric and HPLC analyses of seston, zooplankton and bivalve gut tracts and faeces, trap collections, and sediments. Chloropigment conservation during copepod grazing was examined in experiments conducted at 0°C for 24 hr, using various concentrations of natural seston and cultured diatoms. Transformation to nonfluorescent products was negligible or low (<35%) at seston concentrations >3 μg chlorophyll α/l. At lower food levels, chloropigment destruction was high (>80%). Losses were primarily due to post-starvation feeding and digestive processes. In situ gut and faecal pigment levels in copepods and oikopleurids were highest during mid-bloom production. The dominant copepod grazers exhibited diet feeding rhythms, while oikopleurids showed near-continuous feeding activity. Pyrophaeophorbide a was the primary fluorescent degradation product of copepod grazing; more complex compositions of chlorophyll α derivatives were found in oikopleurid and mussel faeces. Considerable amounts of undegraded chlorophylls were also commonly found in oikopleurid faecal pellets. The contribution of copepod and oikopleurid faecal pellets to the vertical flux of bloom production was highest following the mass sedimentation of primarily senescent diatoms (20-23 m/d) during early May. POC flux to bottom waters was 30-40% of estimated primary production, and 75% of this flux occurred during May. The relative contribution of zooplankton grazing products increased from 35 % at 40 m to 67% at 240 m. Relatively constant carbon/chloropigment ratios at all depths throughout the bloom, and comparable losses of POC and pigment flux between surface and bottom waters, support the use of chloropigments as reliable tracers of vertical flux. C/N ratios of cumulative fluxes were low (7.0-8.8), indicating little decay of the bulk of sedimenting material. High quality particulate material (20% POM) reached near-bottom waters during the terminal phase of the bloom, resulting in elevated carbon and chloropigment levels in the surface sediments. Chloropigment concentrations decreased with sediment depth in the uppermost 5 cm, but composition remained uniform down to 10 cm, presumably due to the bioturbating activities of abundant polychaetes, and pigment preservation processes following burial.

Masters thesis, Memorial University of Newfoundland.

abstract: Nursery culture of the sea scallop, Placopecten magellanicus, is an important transitional phase in hatchery-rearing practices. The Belleoram Sea Scallop Hatchery utilizes the farm-based mesh equipment as the nursery. The purpose of this study was to examine growth rates and recovery of scallops in the farm-based nursery. These factors were monitored with respect to time of year, depth, gear mesh size and type, stocking density, and time of deployment. Remote setting, hatchery flow-through options and ammonia toxicity were also studied for nursery-sized scallops. -- Growth rates of nursery-sized scallops dropped over the winter followed by an increase in the spring. Recovery of scallops (number of live scallops still in equipment after mortality and loss through mesh), however, decreased in the autumn, and leveled off over the winter, which was attributed to handling practices, including the need for acclimation. Growth rates and recovery were highest in the scallops deployed in the largest mesh size which may have been due to better food availability as well as better acclimation by larger scallops. Growth rates were higher in 3.0 mm pearl nets than 3.0 mm collector bags, however, they exhibited the same recovery. The difference in growth may be explained by gear design. No differences in food quantity or temperature existed between 5 and 10 m. however, growth rates were greater at 5 m where fouling was always higher than 10 m. Recovery was similar at both depths. Fouling-induced flow reduction (thus better exploitation of food) or food quality may have influenced growth rates at 5 m. No density dependent effects were noted between 2600 and 5200 spat/bag. Deployment of remote set-or nursery-sized scallops in early to late summer allowed them to have superior growth rates and recovery than deploying during the autumn when temperature and food quantity and quality have dropped. Practicing temperature acclimation and feeding scallops a diet high in essential fatty acids may improve growth and recovery during deployment to sub-optimal farm-based nursery conditions. Scallops held on mesh in flow-through tanks exhibited higher growth than scallops on solid trays. Low growth rates overall in flow-through tanks, however, suggests that flow-through may not be useful for enhancing growth of scallops in autumn sea water temperatures. Summer flow- through trials should be investigated. Ammonia toxicity bioassays suggest that scallops have an increasing tolerance to ammonia with size and that feeding is influenced by the presence of low concentrations of ammonia. -- With this knowledge of important influences of the farm-based nursery, the operators of Belleoram Sea Scallop Hatchery should be able to develop new protocol for scallop nursery practices and thus improve the growth and recovery of their product.

abstract: Verification of integrity and authenticity of information is a prime requirement in computer networks. In open networks such as the Internet, a strong mechanism to provide these security services is essential With the introduction of Internet Protocol Security (IPSEC), the need has arisen to have a simple, efficient and widely available Message Authentication Code (MAC) mechanism. The standard approach for message authentication in Internet applications has been based on the use of cryptographic hash functions such as Secure Hash Algorithm-1 (SHA-1) and Message Digest 5 (MD5). The wide availability of software implementations, efficiency in software and freedom of license and export restrictions are some of the reasons for adoption of hash-based MACs or HMACs. In high-speed network applications hardware encryption and authentication have become essential to meet the performance requirements. Field Programmable Gate Arrays (FPGAs) are an attractive option because they are capable of providing the required speed, algorithm agility and flexibility of dynamic system evolution. When these factors are considered, FPGA devices are a promising alternative for implementing cryptographic algorithms. -- In this research, FPGA implementations of MD5, SHA-1 and HMAC using SHA-1 as the basis hash algorithm have been carried out. MD5 and SHA-1 have been implemented using an iterative and full loop unrolled architectures. The target device has been selected as the XILINX Virtex series FPGA. Performance analysis in terms of hardware utilization and speed are executed. Different design optimization techniques are also discussed. -- The Internet is one of the main areas of application of cryptographic hash functions and the size of the message has a considerable impact on the performance of these algorithms. Hence the performance of HMAC both in hardware and software are investigated using four Internet traffic models. The same analysis is performed on CBC- MAC-AES for performance comparison. -- Due to the sequential nature of the structure of these algorithms, it is difficult to make them fast enough to ensure suitability for very high-speed applications. Therefore some alternative methods have to be investigated for high-speed applications. One of the proposed algorithms based on universal hashing, the Universal Message Authentication Code (UMAC), is analyzed for its hardware performance. Finally the conclusion and recommendations for future research are presented.

abstract: This thesis focuses on the ways in which the folk tradition was perceived and presented by selected twentieth-century Newfoundland authors during the period in which an indigenous literature was developing on the Island, and it argues that, because Newfoundland also witnessed sweeping political, economic and cultural changes during the decades between 1920 and 1970, various conceptions of the worldview, communicative structures, and other expressive forms of the folk tradition provided writers with a means of addressing the anxieties and uncertainties which accompanied the society's transition from a traditional to a modern one. In order to create a framework for the study, Chapter One provides a general overview of the scholarship on the interrelationships between the verbal and written arts in general, and between folklore and literature in particular, and argues that an understanding of this interrelationship is facilitated by the view which sees folklore as the result of repeated patterns and processes and not simply as items or texts. Chapter Two discusses the notion of the folk culture as an intellectual construction in historical and scholarly perspective as related to folkloristics generally, discusses the notion specifically in terms of the Newfoundland context, and advances the concept of a regional mythology as a notion less susceptible to high cultural bias because it evolves as a product of both the folk and literate traditions. Chapter Three presents an overview of the socio-political forces that moulded the evolving Newfoundland society which formed the background against which the indigenous literature developed, and provides a survey of the Island's literary history to 1920. Chapters Four and Five discuss the different responses to the folk tradition in the works of writers who published between 1920 and 1970, and Chapter Five suggests, as a basis for further study, that, once an indigenous literature was fully established, the uses made of the folk tradition by the literate culture were radically different from those which had marked the period during which an indigenous literature was developing.

abstract: The brine shrimp Artemia spp. is a widely used food item in aquaculture. Almost the entire worldwide production of brine shrimp eggs and biomass comes from extensive harvesting of inland saline lakes or coastal solar saltworks. Declining salt prices and growing aquaculture demand has switched the focus to Artemia production in hypersaline environments. NE Brazil has a salt-producing area of 35,000 ha, half of which is abandoned or under strictly artisanal operation. The present research evaluated the effect of supplemental feeding on Artemia franciscana (Brazilian “Macau” population) production and developed semi-intensive culture techniques for this region. -- Preliminary laboratory trials with dried microalgae (Spirulina maxima) were performed to test feeding rations and a feeding table was produced. Low cost feedstuffs available in NE Brazil were evaluated for their digestibility and processing yields, and three brewery by-products were selected (i.e., malt bran, brewer's yeast and spent grains). These were then tested individually and combined in laboratory feeding trials, and their performance was recorded as growth and survival of the Artemia. Malt bran showed significantly better results for both parameters and was selected to be tested in the field. -- Malt bran was efficiently converted into biomass by the Artemia (FCE = 39.16 %) and supplemental feeding was very effective in increasing biomass production. Monthly yields in fertilized control ponds averaged 306.17 kg• ha⁻¹, while feeding ponds produced up to 977.78 kg• ha⁻¹. Increasing feeding levels (rations), although not showing marked differences in size and survival, exhibited gains in individual weight and, consequently, in biomass output. The fatty acid profile of the cultured Artemia was greatly influenced by the diet, while protein content and amino acids did not show significant variations among treatments. -- High salinities were the most efficient predator control method in semi- intensive field systems, and a minimum of 90 ppt was identified as a safe limit to avoid the major predators in the area (i.e., cyclopoid copepods and the fish, Poecilia vivipara). The high mortalities experienced (above 70%) were believed to be related to high temperatures and stocking densities. Measures should be taken to reduce pond water temperature (deeper ponds, shading) and stocking densities below 100 ind• L⁻¹ are recommended.

Masters thesis, Memorial University of Newfoundland.

abstract: This work focused on two sets of comparisons: the first was an inter year comparison of the chick diets and related breeding parameters of Common and Thick-billed Murres (Una aalge and U. lomvia) breeding at the Gannet Islands, Labrador before and after a local decline in capelin abundance. The second was an interspecies comparison of these parameters. In 1996 and 1997, years of locally low capelin abundance, I measured murre chick diet composition , feeding rates, breeding success, chick growth, adult masses, maximum dive depths and off-duty pair members' time spent at site. I then compared these data with those gathered by previous researchers in years when capelin were more abundant (1981, 1982 and 1983). After the decline, murres fed their chicks up to 75 percent less capelin and up to 65 per cent more daubed shannies than they had fifteen years previously. Feeding rates of both species varied by up to 250 per cent among the five years, but this variation was not concomitant with changes in the proportion of capelin in the chicks' diets. The murres' dietary shift did not seem to affect their colony attendance adversely; counts of both murres on some plots increased, while on others they did not differ significantly. Neither murre species had significantly different breeding success among years. Chicks of both species grew well following the decline in capelin availability. Masses of adult murres were not significantly different after capelin became scarce. No time-at-site data were taken before the decline in capelin abundance, but after the decline, members of chick rearing Common and Thick-billed Murre pairs both spent a mean of ten minutes together at their sites per feeding visit. Results from the interspecies comparison suggest that chick food resource partitioning might have been negligible between Common and Thick-billed Murres at the Gannet Islands in 1996 and 1997. In both years, the murres' chick rearing periods overlapped almost exactly. In the year they were both measured, the sizes of the principal item in their chicks'  diets did not differ significantly. During one of two aU- day feeding watches, the murres’ chick feeding peaks were concurrent, but during the other they were not. In the year dive depths of both species were measured, Common and Thick-billed Murres dove to similar maximum depths.

title: Forgetting foundationalism

abstract: Foundationalism is a traditional metaphilosophical position which holds that reality can be explained and described absolutely. Foundationalists maintain that our questions about reality inquire beyond the capabilities of our ordinary language and that, therefore, these questions require absolute answers that are phrased in a metaphysical vocabulary which reaches beyond ordinary language to an absolute reality or metaphysical foundation. I maintain that we should forget foundationalism because the notion of a metaphysical foundation is a needless presupposition that results from incoherent assumptions about the nature of language and reference. -- In order to make a case against foundationalist philosophy I investigate its application to traditional questions addressed by Richard Rorty and Hilary Putnam in the current realism/antirealism debate. I examine both Rorty’s and Putnam's critiques of metaphysical realism, which is a clear example of a foundationalist approach to questions about reality, and I compare the kinds of nonfoundational pragmatism with which they attempt to replace it. -- Although Rorty and Putnam agree that metaphysical realism is incoherent, Putnam professes that he does not agree with Rorty*s replacement - ethnocentric pragmatism. However, my comparison of Rorty*s ethnocentric pragmatism with Putnam's natural realism reveals that, despite Putnam's criticism of Rorty's position, both positions are remarkably similar. In his arguments against metaphysical realism Putnam clearly recognizes the incoherence of foundationalism, but Putnam's charge of relativism against Rorty contradicts the very arguments that Putnam himself employs against metaphysical realism. I contend that Putnam's discomfort with Rorty’s ethnocentrism suggests that Putnam has not quite succeeded in forgetting foundationalism. -- The postmodern recommendation to forget foundationalism is not a new one; Wittgenstein proposed it in his Philosophical Investigations fifty years ago and Rorty and Putnam are proposing it now. I am reiterating this recommendation in order to show that the criticism Rorty (especially) and Putnam have received is an unwarranted and often dogmatic refusal to accept the limits of philosophical inquiry.

abstract: This thesis examines an important topic in international relations which has preoccupied diplomats for thousands of years and for the better part of this century — the evolution of the law of the sea. Some recent changes can be linked to new technologies and the growing concern about fishery conservation. It is argued that changes in the law of the sea are essentially evolutionary in character, notwithstanding the recognition that crisis situations provide periodic stimuli towards some kind of action. -- In this century, three distinct phases and events have shaped the development of the law of the sea, with regard to straddling stocks. The United Nations Convention on the Law of the Sea is the foundation for modem sea law and serves as the basis for discussion. Increased understanding of the oceans and expressions of heightened concern for protecting and sustaining the marine environment, including fisheries, were an important themes at the 1992 United Nations Conference on the Environment and Development. Thirdly, the New York Conference on Straddling Fish Stocks and Highly Migratory Fish Stocks, and its resultant draft treaty, has provided a framework within which fisheries law can change and develop. -- In light of the deteriorating state of the global environment and the rapidly declining fish stocks, it is argued that international law must respond more rapidly and effectively to meet environmentally destructive technological developments, if the international marine eco-system is to be preserved for future generations.

abstract: Studies have shown that the integration of wind turbines into an autonomous diesel- electric system (i.e., wind-diesel) can be economically viable, and that the potential market for wind-diesel is considerable. High-penetration, no-storage wind-diesel (HPNSWD) is considered to be the most economical approach to implementing wind-diesel. A HPNSWD system requires a fast-acting dump load controller to maintain the system frequency stability and quality, and, under some applications, additional voltage control is needed to maintain the voltage quality. -- In this thesis a detailed comprehensive dynamic model of a HPNSWD system is presented. The model is implemented in the software packages Matlab and Simulink, and is based on the wind-diesel test-bed at the Atlantic Wind Test Site (AWRS) in PEL Canada. Simulations using 1st 2nd and 3rd-order electric machine models are compared with simulations using the full-order electric machine models. Wherever possible, components of the model are validated with available measurements from the AWTS system. -- Three different frequency transducers (one phase detector and two frequency detectors) are modelled and incorporated into the design of a PID dump load frequency controller. The fast frequency detector (360 Hz pulse rate) outperforms the phase detector of the same speed. The slow frequency detector (36 Hz pulse rate) is unable to sufficiently dampen the swing of the system against the wind turbine's rotor. -- The simulated voltage transients that result from the disconnection of the wind turbine are found to be well above the specified limit When a capacitor bank is added to the wind turbine these voltage transients are reduced, but the susceptibility of the system to flicker emissions due to wind turbulence remains high and unchanged. -- In this thesis, a static VAR compensator (SVC) is uniquely applied to the wind-diesel system to improve its voltage stability. With the SVC configured to compensate the reactive power of the wind turbine, the wind turbine disconnections yield similar responses as with the capacitor bank, but the flicker emissions due to wind turbulence are virtually eliminated. Adding a novel voltage control loop to the SVC reduces the voltage transients from the wind turbine disconnections to well within the specifications. In addition, the voltage stability of the entire system is improved.

abstract: This study examines the phenomenon of Fascism in Canada during the Depression and how the authorities, primarily the Royal Canadian Mounted Police, chose to deal with it. The topic of Canadian Fascism has been largely ignored in favour of the more fashionable topic of Communism.  Fascism was never a large scale movement in Canada; it did, however, effect portions of the German and Italian communities as well as individual French and English Canadians. -- The conventional view of the RCMP Security Service argues that the RCMP ignored Fascist movements until external events caused them to take internal actions. I would challenge this-argument, marshaling evidence that the RCMP was indeed watching Fascist organizations from their inception, although choosing not to view them as a serious threat. The RCMP began investigating Fascist movements in Canada in the early 1930's but did not view them as much of a threat, seeing them as largely disorganized and, if not as potential allies in their fight against Communists, at least as the lesser of two evils. As both the RCMP and the Fascists were anti-Communists, the RCMP viewed Fascists with rather a benevolent eye. The RCMP was more ideologically to the right and this effected how the RCMP viewed both Fascists and Communists. -- Once war broke out the Canadian Government decided to act against groups it had consistently said were not dangerous.  For years the Government, via the RCMP and other government departments, turned a blind eye to foreign interference by the Consuls in both the German and Italian communities, choosing to view events in the immigrant communities as matters for the communities to decide.  By viewing Fascism as a limited threat and by allowing foreign coercion to occur in Canada it can be argued that the Canadian government failed to defend its own citizens.

abstract: This thesis presents an artificial neural network system for edge detection and edge enhancement. The system can accomplish the following tasks: (a) obtain edges; (b) enhance edges by recovering missing edges and eliminate false edges caused by noise. The research is comprised of three stages, namely, adaptive fuzzification which is employed to fuzzify the input patterns, edge detection by a three-layer feedforward fuzzy neural network, and edge enhancement by a modified Hopfield neural network. The typical sample patterns are first fuzzified. Then they are used to train the proposed fuzzy neural network. After that, the trained network is able to determine the edge elements with eight orientations. Pixels having high edge membership are traced for further processing. Based on constraint satisfaction and the competitive mechanism, interconnections among neurons are determined n the Hopfield neural network. A criterion is provided to find the final stable result which contains the enhanced edge measurement. -- The proposed neural networks are simulated on a SUN Sparc station. One hundred and twenty-three training samples are well chosen to cover all the edge and non-edge cases and the performance of the system will not be improved by adding more training samples. Test images are degraded by random noise up to 30% of the original images. Compared with standard edge detection operators, the proposed fuzzy neural network obtains very good results.

Masters thesis, Memorial University of Newfoundland.

abstract: To describe the temporal spawning of cod and its relation to water temperature, sexual maturity, length, and age, the condition and gonado-somatic index of Atlantic cod sampled at four sites in northern Placentia Bay were monitored from March 1998 to April 1999. Similar information collected by the Department of Fisheries and Oceans over 1995-1997 was added to this data set. A histological procedure was used to verify spawning condition and improve the visual classification of spawning females. The visual classification was found to underestimate the percentage of spawning females by up to 29.7 %. No significant differences of biological variables and temperatures were found among the four fishing locations. Spawning fish were present from March to August, and several peak spawning periods per year were observed. A correlation between spawning patterns and temperature existed, but with a difference between sexes. Catch per unit effort, which gave a representative image of movement and abundance of fish, was more important in fixed than free locations, and was low during the spawning season.

abstract: While advertising permeates many aspects of our lives, how it is perceived to influence the choices we make around areas that can have a marked effect on our health has been relatively unexplored. The purpose in this phenomenoiogical study is to use cigarette advertising found in magazines targeted towards young adolescent women as a hermeneutic prompt and explore the questions: What are the social pressures on young women to smoke that are reinforced through cigarette advertisements? and, How do they experience these social pressures? Through the use of phenomenoiogical methodology, the study aims to provide nurses and others with a richer and deeper understanding of young women and smoking. -- The experience of social pressures on young adolescent women to smoke that are reinforced through cigarette advertising is a complex interrelationship among the following themes: Being with others: smoking is a social event, Being like your peers: developmental issues, Parents, family and other important relationships matter, Not having an effective voice, Addiction warnings are not enough: you don't read the small print, Leading by misleading: seeing through the ads, and Smoke and you will be attractive, popular and slim: myths in ads. Through these themes a greater understanding of just how easy it is for young women to smoke is more clearly understood. The essence of the lived experience of the young women is, It is so easy to smoke. The findings also provide some insights into why smoking prevention and cessation programs targeted towards this group may not have the desired effect in practice. Implications for nursing practice and education, nursing research, and health policy are discussed.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: The comparative respiratory metabolism of Asterias vulgaris and Leptasterias polaris was determined by oxygen consumption  measurements   in both  whole organisms and excised  tissues under different   temperatures.  Oxygen consumption was   measured by using Winkler' s method for whole organisms and  by  the Warburg  technique for  excised tissues. Various levels of some important environmental   factors  influencing  the oxygen  consumption of whole sea stars were  evaluated. Statistical analyses were  applied to estimate and compare the effect of these  factors on respiration  in both  species of  sea stars. – The relation between the body weight of sea stars and oxygen consumption was  expressed as   a logarithmic linear regression. Regression lines  of oxygen consumption of  whole  sea stars rise from  0°C  to 5°C. The mean  slope of the regression  line was 0.72-0.89 for A. vulgaris and   0-75-0.92 for L. polaris.  There  is no significant difference in oxygen consumption  of whole sea stars between the   sexes  within  a  species.  L.  polaris has   a lower  oxygen consumption  than  A.  vulgaris  except in the larger  L. polaris at 15°C. The  oxygen  consumption rate of sea  stars is dependent  on  the  ambient  oxygen content  in the  sea water. The  relationship showed  a curvilinear instead of simple linear  correlation as  general  oxyconformer  invertebrates do.  The oxygen  consumption  rate decreases  as  the pH value in sea water is changed  from normal  sea water.  The oxygen  consumption rate  of sea stars  decreased more sharply with  pH values above that of  normal  sea water (toward basic) compared to pH  value below that of normal sea water.  A. vulgaris is more sensitive than  L. polaris to the  pH effect.  Salinity  changes above or below the salinity  of  normal  sea  water also reduced oxygen consumption   rate.  Short-term  food  deprivation  does not  affect  the oxygen consumption  of sea  stars.  The oxygen consumption rate  of various tissues  in sea stars showed a tendency  similar to that of   whole  sea  stars,  but the slopes varied  greatly for different  tissues. Some regression lines are not significant at the 5%  level.  It may be due to the different relative weights  of various organs. Coelomic fluid exhibited the lowest  oxygen uptake  because there are few living cells in the fluid. The mature  gonad of male  sea stars indicate positive correlation between body weights and  the oxygen consumption  rate. This is as expected because the mature and full  grown sea star would more likely possess  active sperm. -- The moving speed of A. vulgaris is faster than that of   L. ,polaris  and  is  more sensitive   to temperature  change. The moving speed of sea stars is not related to body weight,  but  righting  response time is a function of body weight. The smaller sea stars require less time to right themselves. When both  species  employed the same righting method,  there  was  no significant difference  between them. However, most  larger sizes of  L. Polaris  quite often applied the tulip method which  consumes more time than the rest. Temperature does affect the uptake of amino acids. A. vulgaris appears to have better absorption capacity at high temperature.  On the other hand,  L.   polaris exhibits better ability at low temperature. A.  vulgaris  is distributed from Southern Labrador to   Cape Hatteras. This species can be found in shallow water in Northern North America, but south of Long  Island Sound,  it is not found along the  shore. Temperature limits their distribution to deeper and  cooler water in more southern regions. Therefore,  it  is classified  as a boreal  species. On the other hand, L.  Polaris occurs from the high  Arctic region to Nova Scotia and can be recognized as an Arctic   species.

abstract: On Canada's eastern seaboard where hydrocarbon deposits have now been determined, the operational hazards are numerous. Damage by icebergs to installations on and in the ocean floor is one of the major threats. An understanding of the Interaction of an iceberg with the continental shelf surface sediment during the process of grounding is needed to establish safe design standards for bottom structures in offshore drilling operations. Knowledge of icebergs, their size, shape and drift, is still very limited and so is the engineering behavior of the surface sediment of the oceans. -- In this thesis, the behavior of an iceberg of idealized shape is analyzed while it grounds in a uniform slope of very weak and compressible sediment. An expression was derived for the  theoretical size of the scour that could be caused and this was substantiated by laboratory experiments. -- A tiltable towing tank was fabricated in which a 9” wide plexiglass model of the idealised iceberg was tested. Forces and pressures on the model were measured during the process of its scouring into an artificially sedimented  slope. The frontal soil resistance was found to be the predominanting force confirming the assumptions made. Soil failure was dominantly local. A soil front of about 5 feet was under compression during the gouging process and a similar phenomenon was also noticed below the maximum scour depth.  About 30% of the pushing effort was computed to be lost in the compression.  Observations in a small tank with 2” wide models confirmed the soil compression phenomenon and also led to a qualitative understanding of the effects of Iceberg shape. -- Scour sizes, computed and compared with reported side-scan observations off the Newfoundland  coast showed that the predictions made by the analytical model are realistic.

abstract: This thesis presents a novel technique of speed control for permanent magnet (PM) motors. Robust and precise speed control is of critical importance in the high performance drive applications. Unavoidable system disturbances, such as parameter variations, effects of sudden load impact and other system noises are resolved by developing on-line self tuning artificial neural network control structures for both PM dc and PM brushless synchronous motor drives. The newly devised artificial neural network controllers are capable of overcoming the limitations of model dependent conventional fixed gain and existing adaptive speed controllers. -- Utilizing the concepts of inverse motor dynamics and non-linear load characteristics, artificial neural network based controllers arc designed on the basis of feed-forward neural networks. The transient arid dynamic behaviors of the proposed drive systems are improved by incorporating a unique feature of adaptive-learning rate which aids the on-line robust speed control over a wide operating range. The stability of the proposed systems has been ensured by a combination of off-line and on-line trainings of the artificial neural networks. -- As an integral part of this work, efforts have been directed at the real-time implementation of the artificial neural network based PM motor drive systems using a digital signal processor (DSP) controller board-DS 1102. A new circuit topology has been developed in order to lessen the computation burden of the DSP controller board for the implementation of the PM brushless synchronous motor drive system. A series of tests has been carried out with both PM dc and PM synchronous motors in order to evaluate the performances of the artificial neural network based drive systems. The laboratory test results validate the feasibility of the artificial neural network as an adaptive controller in the high performance drives.

title: Spiritual concepts in therapeutic touch

abstract: This work examines the partial acceptance by the Western medical establishment of Therapeutic Touch as a form of medical treatment in Western orthodox medicine. The primary focus of this thesis is on how Dolores Krieger, founder of TT, was able to successfully introduce this healing practice into Western medical establishments such as nursing schools, medical clinics, and hospitals, despite its basis in Eastern philosophical, metaphysical, and medical concepts such as prana , ch'i , chakras , and the theory of yin-yang . Therapeutic Touch emphasizes the concept of "human energy" transference, an idea borrowed from Eastern belief systems that suggest that humans are energy systems, interconnected with all things in the cosmos. Within Indian cultural context, for example, the concept of "human energy" has historically been known as prana. Within the cultural context of China, the term ch'i has been used to refer to human energy systems. Krieger borrows these concepts of "energy" to explain her own system of healing. By examining and comparing the work of Dolores Krieger with these Eastern concepts in their historical, philosophical and spiritual contexts, this work will illustrate how Dolores Krieger minimized, Westernized, and medicalized these concepts in order for the practice of Therapeutic Touch to gain partial acceptance in the field of Western, allopathic medicine.

abstract: In 1621, Captain Edward Wynne (along with 11 settlers) established a colony at Ferryland, Newfoundland, on behalf of George Calvert. Recent archaeological excavations uncovered a number of structures associated with this initial settlement as well as those built later. These excavations also uncovered over 1,000,000 artifacts, including thousands of fragments of wine and case bottles. Although the historical record suggests that the inhabitants of Ferryland were avid consumers of alcohol, there are few direct references to glass bottles or other containers associated with alcohol consumption. Thus, the analysis of bottle fragments will provide answers to several questions relating to consumption as well as social status. Four different glass assemblages representing different functional areas and time periods were examined in order to identify any changes over time. Such an analysis required the formulation of a model that allowed for the accurate dating of fragments. Based on a number of measurements taken on bottles of known dates or those excavated from well-dated contexts, this model provides a means not only for dating fragments uncovered in future excavations at the Ferryland site but on other historic archaeological sites of the period.

Masters thesis, Memorial University of Newfoundland.

abstract: During a 1993 survey of eighteenth-century civilian gun batteries on The Mount in Renews, Newfoundland evidence of a seventeenth-century occupation was uncovered. Subsequent excavation of the site in the summer of 1994 exposed the foundation and internal features of a one-room domestic structure and more than 34,000 artifacts. Many of these artifacts, including several tools associated with the fishery, were associated with the occupation of the site during the third quarter of the seventeenth century. Ceramics and other artifacts from the Barnstable and Bideford area of north Devonshire in England's West Country dominated the assemblage. Fifty ceramic vessels were identified from the pot sherds, including many vessels associated with the storage, preparation, presentation and consumption of food and drink. Other ceramic and glass vessels were associated with medicinal products. The nature of the artifacts from the seventeenth-century deposits, together with the substantial structural remains, suggest that a long-term habitation had occurred at this site. -- This thesis describes and interprets the findings from the site including the architectural remains and the artifactual remains. Chapter I introduces the site and its physiography and the early historical background to Renews. The methodology employed for the study is also explained in this chapter as are the dating techniques and the site stratigraphy. Chapter II focuses on the architectural evidence and describes each element of the house present within the archaeological record. Missing elements of the dwelling are inferred by the archaeological and historical evidence. Chapter HI is dedicated to the artifacts discovered on the site. The research parameters are described as are all the major artifact groups. Chapter IV offers interpretations on what the various artifacts represent and what they can tell about the life of a planter in Renews during the seventeenth century. The artifact assemblage was analyzed in a way to allow for inferences to be made regarding several important facets of seventeenth-century life on the site. These facets include foodways, health care, leisure activities and occupational activities. Chapter V concludes the study by summarizing the findings. The appendices contain the figures and information on clay tobacco pipe stem bore analysis, Event descriptions and an informative report on pollen discovered in the seventeenth-century cultural deposits.

abstract: Very little documentation exists on the architecture and construction techniques employed at early colonial establishments in seventeenth-century Newfoundland.  In those cases when records have been kept, descriptions are often only from the fledgling years of the colonial venture or are vague and hence, open to broad interpretation.  It is for these reasons that archaeological excavation is vital to our understanding of how colonists constructed their buildings, which tools they used and from where the raw materials originated. -- This thesis focuses on seventeenth-century stone construction as reflected in the archaeological remains excavated at Ferryland, Newfoundland (site Area C). The main points of investigation centre on the location of quarry sites used by early colonists, the dates to which Area C's structures were constructed, the functions of the buildings, the various construction techniques used in building these structures, the use of slate for roofing, possible Welsh or Devon construction influences and several aspects of colonial planning and economics. All of these topics were researched using a combination of geologic survey, artifact analysis, excavation, fieldwork in Britain, the recording of construction techniques and study of historical documents. -- The results show that Area C's stone structures were constructed in two separate phases, one in the 1620s and the second in the fourth quarter of the seventeenth century. A massive stone seawall, privy and slate-roofed storehouse constituted the first series of structures which were in use until the Dutch raid of 1673. Soon after this raid, a second structure was erected at Area C and served as a cowhouse-storage shed. This building, like many of the others at Ferryland, was destroyed as a result of the French attack in 1696. -- Both building phases involved the construction of thick slate-stone walls and flagstone or cobblestone floors. The raw materials for which were obtained from nearby slate/shale outcrops and a cobblestone beach.  Thousands of roof slate fragments were also found in association with the storehouse destruction. From these remains it was possible to ascertain the slate sizes used at Area C and the various steps involved in the construction of a slate roof. -- The historical records and archaeological remains demonstrate that craftsmen from either Wales or Devon could have been involved in the first construction phase at Area C.  By studying these stone structures it was also determined why Area C's waterfront buildings were constructed entirely of stone, how they played a integral role in the economics and operations of the early colony and how the changing lives of Ferryland's colonists are reflected in the two different construction phases.

abstract: This thesis explores the social construction of female sexuality in popular women's magazines and draws attention to the commercial interests that are served by the simultaneous processes of creating sexual difference and sexing desire. The teen magazines Seventeen, Ym, and Teen, and the young women's magazines Cosmo, Glamour, and New Woman, are used to track the cultivation of a specifically feminine form of desire, a form of desire which is differentiated from masculine desire, offered only to female bodies, and which bears no inherent relation to female bodies. It is shown that for the purposes of generating revenue, the cosmetic, fashion, diet, and magazine industries participate in the creation of feminine desire. In these magazines, feminine desire is established as the desire for male sexual desire and for committed, monogamous relationships while male desire is characterized as the desire for sexual gratification. This thesis also elucidates the ways that popular women's magazines often react to the differences that they themselves have helped to create. Numerous contradictions become visible through an examination of the advice given to readers on how to deal with or overcome the consequences of sexed desire. Ultimately, my analysis reveals that contradiction is a key feature of the women's magazines' treatment of female sexuality and suggests that contradiction may be an integral part of the magazines’ success.

abstract: The Shear Lag Effect reduces the ultimate net-section capacity of steel members due to uneven stress distribution at the connection zone. Bolted connections have been studied in detail for shear lag. The applicable design specifications for both bolted and welded members are currently based on the behavior of bolt-connected elements. There is a need for investigating such assumed similarities with weld-connected members. -- An experimental study was therefore carried out on welded steel members in tension. It included twenty-seven steel plate specimens and twenty-two steel angle specimens with different weld configurations. Analytical studies using finite element techniques were carried out. Material non-linearity including strain hardening effects and large deformation effects were considered in the analysis. The effects of various parameters were studied experimentally and analytically. Physical parameters such as length of member, size of member, length of connection, configuration of connections and material parameters such as ratio of yield stress and ultimate stress were considered. A study was also carried out to obtain an elastic solution using Fourier Series for discontinuous tensile loading. -- The relevant current design provisions of North American specifications have been examined. Efficiencies predicted by these standards were compared with the experimental results. Modifications to the standards have been recommended.

Masters thesis, Memorial University of Newfoundland.

abstract: Nickel is a ubiquitous trace metal which occurs in soil, water, air, and in the biosphere. Some nickel compounds have been shown to induce tumor at injection site in animals. Lung and nasal cancers have been observed in workers at nickel refineries. The mining of nickel in Voisey's Bay may possibly pose risks of environmental concern, especially to aquatic species. The sublethal effects of nickel subsulfide and nickel ore with respect to oxidative damage, antioxidant and detoxicating enzymes were examined in short term studies in rats. -- The rats were given nickel subsulfide (100 mg/rat or 200 mg/rat), i.p., as a single dose or two doses, 2 weeks prior to sacrifice. Nickel subsulfide suppressed catalase and superoxide dismutase (SOD) activities in rat liver but not in kidney. The inhibition in hepatic SOD showed a dose-dependent relationship. The decrease of hepatic catalase and SOD by nickel subsulfide could be a reflection of nickel insult which could make target tissues more vulnerable under oxidative stress. -- Other groups of rats were given nickel ore (100, 200 mg/rat), i.p., as a single dose, two days, one week or two weeks prior to sacrifice. Nickel ore treatment did not affect lipid peroxidation, protein carbonyi content, aminolevulinic dehydratase, catalase, superoxide dismutase, glutathione peroxidase, glutathione levels, glutathione reductase, glutathione S- transferase (l-nitro-2,4-dichlorobenzene, ethacrynic acid, trans-4-phenyi-3-buten-3-one) in rat liver or kidney to any significant extent. A statistically significant increase was observed in liver NAD(P)H: quinone reductase activity in the group treated with 200 mg/rat (2 w); the enhancement rate averaged 117%. An significant increase also occurred in kidney glutathione S-transferase (l-chloro-2,4-dinitrobenzene) activity in the groups treated with 100, 200 mg/rat (2 d) and this activation seemed to be induced in a dose-dependent manner. It appears that nickel ore does not pose a serious toxic insult to rats in short term studies and hence the risk posed to aquatic species could be minor. However, long-term studies with rainbow trout and bivalves need to be conducted to investigate possible risks of more broadscale environmental concern.

abstract: Estimation of inelastic strains in notched mechanical components and structures are necessary for low cycle fatigue evaluations. This has been a topic of considerable interest to pressure vessel designers. -- The Generalized Local Stress Strain (GLOSS) method is a robust technique that is based on two linear elastic finite element analyses, and has been used for evaluating inelastic strains in pressure components subjected to mechanical loadings. This thesis endeavors to determine the inelastic strains of components and structures that are subjected to both mechanical as well as thermal loadings. A two bar kinematic model is used to explain the fundamental aspects of modulus reduction method. Using the elastic-inelastic equivalence, a procedure to obtain the complete relaxation locus has been provided. Based on the relaxation locus, the GLOSS method is extended for combined mechanical and thermal loadings.  -- In this thesis, GLOSS method is applied to several pressure component configurations of practical interest. The strain estimates are then validated by comparing them with inelastic finite element results.

abstract: A descriptive correlational design was used to investigate acute care nurses' perceptions of the impact of health care reforms and their work-related attitudes and behavioral intentions following restructuring of acute care services in Newfoundland and Labrador. The interrelationships among the key study variables (i.e., personal characteristics and staffing issues, impact of reforms, work-related attitudes, and behavioral intentions) were also examined. The Conceptual Model of Behavioral Intentions (CMBI) was used as the framework for this study. -- The stratified random sample was comprised of 223 registered nurses working in acute care settings under the institutional/integrated boards responsible for health care services in the eight health districts of the province of Newfoundland and Labrador. A response rate of 34.1% was achieved. The majority of respondents were female (97.8%), had a diploma/certificate education level (86.1%), were employed on a full-time permanent basis (76.2%), had 10 or more years of nursing experience (74%), were in their current positions for less than 10 years (64.1%), and were employed in facilities outside of the St. John's region (58.8%). The mean age of the sample was 38.26 {SD ±8.07). Data were collected via a mail-out questionnaire (i.e., Employee Attitudes Survey) between November, 1999 and February, 2000. -- Study findings indicated that acute care nurses were generally negative about the overall impact of health care reforms five to six years post- implementation. Respondents were most negative about the emotional climate of the workplace and the quality of care, and most positive about the importance of reforms. As well, most respondents felt their employers had violated psychological contracts made upon hiring, were generally dissatisfied with their jobs, had slightly low levels of commitment to their organizations, and were uncertain about staying with current employers. -- Most of the reform impact variables (i.e., importance of reforms, emotional climate, practice-related issues, quality of care, safety concerns, and standards of care) depicted significant, positive relationships with intervening attitudes (i.e., psychological contract violation, restructuring satisfaction, job satisfaction, and organizational commitment) and behavioral intentions (i.e., intent to stay). As well, intervening attitudes depicted significant, positive relationships with each other and behavioral intentions. Several personal characteristics (i.e., employment status, work experience, current position tenure, and age) and most staffing issues variables exerted a minimal, but significant, influence on work- related attitudes and behavioral intentions. -- Study findings provided partial support for the major assumptions of the CMBI. Consistent with model predictions different combinations of reform impact variables exerted a direct effect on intermediate outcomes (i.e., psychological contract violation, restructuring satisfaction, job satisfaction, and organizational commitment) and behavioral intentions. As well, most intermediate outcomes were strong predictors of one another and behavioral intentions. As predicted, personal characteristics and staffing issues had limited influence on intermediate outcomes and behavioral intentions. Importantly, study findings did not always support the causal, linear process proposed by the CMBI (i.e., mediating influence of intervening attitudes for the reform impact variables and each other). -- Although study findings supported previous research, generalizability of the results to other acute care nurses is cautioned. There is an obvious need for further research to develop a greater understanding of those aspects of the job and work environment most affected by health care reforms in the acute care sector. Most importantly, the onus is on health care researchers to investigate the long-term impact of system changes on nurses' work-related attitudes and behavioral intentions.

title: Image segmentation for coding

abstract: The segmentation of regions is an important first step for a variety of image analysis and visualization tasks. There is a wide range of image segmentation techniques in the literature. Conventional segmentation techniques for monochromatic images can be categorized into two distinct approaches. One is region based, which relies on the homogeneity of spatially localized features, whereas the other is based on boundary finding, using discontinuity measures. Based on one or both of these properties, diverse approaches to image segmentation exhibiting different characteristics have been suggested in the literature. -- The research of this thesis was aimed at combining region growing and edge detection methods to provide better segmentation results. Existing schemes that use region-based processing provide unambiguous segmentation, but they often divide regions that are not clearly separated, while merging regions across a break in an otherwise strong edge. Edge-based schemes are subject to noise and global variation in the picture (e.g. illumination), but do reliably identify strong boundaries. The proposed combined algorithm begins by using region growing to produce an over-segmented image. This phase is fast (order N, where N is the number of pels in the image). The over-segmented output of the region growing is then modified using edge criteria such as edge strength, edge straightness, edge smoothness and edge continuity. Two techniques - line-segment subtraction and line-segment addition - have been investigated. In the subtraction technique, the weakest edge (based on a weighted combination of the criteria) is removed at each step. Every time that a weakest edge is removed, the combined edge strengths of the remaining edges are recalculated. In the addition technique, the strongest edge (based on the weighted combination of all criteria) of all the edges is calculated first. It is used to seed a multi-segment line that grows out from it at both ends. At each end of the strongest edge, a binary tree containing four branches is investigated. The adjoining edge that has the highest edge strength is appended to the seed. This process of appending continues until a closed loop or a boundary is reached. The overall procedure for both techniques for segmentation has been developed. -- In order to investigate the performance of the proposed segmentation techniques, a segmentation evaluation method is demonstrated. Since a human is the ultimate judge, a subjective evaluation method is developed. Segmentation produced by a human is compared to segmentation produced by the algorithm and correlation is calculated between the human method and the algorithms. Subjective tests performed on the algorithms and the results confirm that the proposed algorithms can be used to produce better image segmentation than the segmentation produced by existing region-based techniques.

abstract: This thesis explores the line of fault (Smith, 1987) between women's experiences in the fishery crisis in Newfoundland and Labrador and the construction of the fishery crisis in the print media in this province. -- An analytical framework based on the work of Dorothy Smith guides the analysis. Smith (1987: 50) argues that a line of fault or a disjuncture between experiences and the forms in which these experiences are socially expressed occurs in society. In this case, the experiences of women in the fishery crisis as expressed in a series of workshops entitled Gathering Our Voices are contrasted with the results of a media analysis of The Evening Telegram coverage of the crisis. This analysis reveals two different stories: women's expressed realities in the fishery crisis and the expression and framing of the fishery crisis in the print media. -- Women are under represented in the print media of Newfoundland and Labrador. Their absence as authorized knowers, reporters, and in news photos show that there is a lack of news stories written from women's point of view. A qualitative analysis of The Evening Telegram also shows that women's issues and concerns are not represented in the coverage of the fishery crisis. Instead, the fishery crisis is framed from a male centered point of view in the print media. -- Women's experiences in the fishery crisis are unique and different from men's as women held different roles in the paid and unpaid sectors of the fishing industry. Women worked as mothers, wives and daughters in the household and as fish plant workers and harvesters in the paid sectors of the fishery. Women are concerned about themselves, their families and their future in the rural fishing communities of Newfoundland and Labrador.

abstract: This project presents research findings regarding multi-age education and practical ideas for the implementation of a multi-age approach to teaching and learning. This project grew out of a need in School District # 3 for a handbook outlining material on multi-age education. A committee was struck to draft policies, guidelines and procedures for multi-age classrooms within the District. The committee completed this task in draft form. This project is intended to support the work of the District committee and to be a resource for teachers interested in teaching in a multi-age setting. The data for this project was collected from four primary sources: a comprehensive review of literature, document analysis, surveys, as well as observations and personal experiences of the author. The surveys were developed and administered to teachers, principals and parents involved with multi-age education within the District. The results of these surveys confirm the research findings from prominent researchers as well as personal experiences of the author that indicate quite clearly the value of a multi-age approach to teaching and learning. Once compiled, the results of the surveys were incorporated into a multi-age handbook outlining research findings, implementation, and day-to-day practices for the use of teachers wishing to learn more about the multi-age approach to teaching and learning.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: The Gram negative bacterial fish pathogen Aeromonas salmonicida is the causative agent of furunculosis in salmonid fishes.  The lipopolysaccharide (LPS) from A. salmonicida, a major factor in determining bacterial virulence, was incorporated into liposomes to determine the ability of these formulations to function as delivery vehicles and immunological adjuvants in rainbow trout (Oncorhynchus mykiss).  Several aspects were considered important in examining the potential of liposomal LPS formulations as vehicles and adjuvants. -- 1H-Nuclear Magnetic Resonance (1H-NMR), mass spectroscopic (MS), and polyacrylamide gel electrophoresis (SDS-PAGE) analyses indicated that the LPS from A. salmonicida was consistent with the structures previously proposed for the O- antigen and the core-oligosaccharide moieties using conventional chemical analyses. These studies also suggested that an unusual resonance at 0 ppm in the 1H-NMR spectrum of the LPS may relate to both the LPS and a component of the antifoaming agent, Antifoam A™. -- Incorporation studies demonstrated that LPS and PS from A. salmonicida can be incorporated into multi- and unilamellar vesicles composed of both positively and negatively charged lipid to form liposomes of varying incorporation ratios, sizes and lamellarities, -- Biodistribution studies indicated that the uptake of LPS, liposomes, and liposomally-incorporated LPS administered via the IV, IP and IM routes was primarily by the kidney and spleen in rainbow trout.   Although oral administration of the antigens resulted in the lowest overall uptake, an enhanced uptake by the liver was observed as compared to the other tissues and organs examined.  These results propose that liposomes may serve as efficient delivery vehicles for LPS to the primary hemopoietic organs of rainbow trout. -- Immunization experiments demonstrated that multi- and unilamellar vesicles composed of both positively and negatively charged lipid are capable of prolonging the humoral immune response to LPS from A. salmonicida in rainbow trout when compared to the non-incorporated LPS. -- ABx chromatography is a practical procedure for the purification of rainbow trout immunoglobulins from serum.  It is likely that this protocol may be adapted for the isolation of IgM from other fish species. -- Our data suggests that liposomally-incorporated LPS can safely be administered to rainbow trout and function as delivery vehicles and immunological adjuvants.  These results propose that liposomal LPS formulations are worthy of farther investigation in terms of potential and application in rainbow trout.

abstract: The performance of smart antenna in an indoor environment, with the emphasis on improving the system capacity of direct sequence code division multiple access (DS-CDMA) base station is studied. A model for the uplink CDMA is presented which assumes that the base station alone uses an antenna array to transmit and receive signals. In the channel model we assume that the signal bandwidth is much larger than the coherence bandwidth to assure the existence of resolvable paths. The base station uses Differential Phase Shift Keying (DSPK) for modulation and a RAKE receiver. -- Evaluation of different performance measures such as bit error probability and outage probability is performed. A significant improvement in capacity for the 8 sensors smart antenna over the conventional one antenna element is achieved.
