description: Cancer is predominantly a disease affecting older persons. 43% of new cancer cases in Canada occur among those who are at least 70 years old, while 25% occur in those aged 60--69 years. Cancer fatigue is the most common symptom associated with cancer and its treatment, and is often the most distressing symptom reported by cancer patients. Cancer fatigue adversely affects physical activity levels, physical function, and quality of life. Physical function is essential to older adults in maintaining independence and associated quality of life which is often more important to older adults than cancer survival. Recent research studies suggest that physical activity may reduce fatigue, and maintain or improve physical function levels and quality of life in cancer patients during and following treatment. This thesis examines cancer fatigue and its relationship to physical activity, physical function, and quality of life in older adults with cancer. The results of a systematic review and the findings of a secondary analysis research study are presented. The systematic review provided evidence that physical activity may reduce fatigue in older cancer patients during and after cancer treatment and may help to maintain or improve physical function and quality of life in this population. Results of the secondary analysis indicated that cancer fatigue is prevalent and was the most frequently reported symptom at baseline, three months and six months post consultation for cancer treatment. Cancer fatigue was associated with lower levels of physical function and quality of life. Physical activity, a modifiable factor, was found to be significantly related to cancer fatigue at three months and six months, regardless of age, and was significantly related to physical function at six months.

description: Chinese historical places, with their extensive history spanning thousands of years, serve as profound symbols of the nation's rich cultural legacy. Capturing their historical changes in a consistent data model for describing cultural heritage, however, poses significant challenges due to shifts in the places’ name, administrative boundaries, administrative units, and geographical locations. Various data models on platforms like Wikidata offer differing approaches: some separate place names and locations into distinct classes, while others consolidate them. This poster showcases the authors’ investigation into different data models for describing cultural heritage historical places and their chosen approach. By leveraging Wikibase as a testbed database, the authors delve into the merits and limitations of each data model, unveiling the techniques employed for bulk data creation, complexities encountered, and valuable insights derived from this exploration.

description: This thesis describes the immunization protocols for the production of antibodies against tetanus toxin and toxoid in guinea pigs and mice. Antibodies were successfully raised against the toxin without mortalities in either species. The murine sera obtained, were isotyped by ELISA and the toxin was proven to be a superior antigen in eliciting production of IgG$\rm\sb{2a}$ and IgG$\sb3$. The two isotypes which have demonstrated antitumor activity. The anti-toxoid sera exhibited a lower reactivity towards the toxin and toxoid when compared with anti-toxin sera. The reactivity of recombinant tetanus toxin fragment C was studied and the results indicated that in the murine serum, 72% of anti-toxin or anti-toxoid antibodies were directed against epitopes on fragment C. The study of the guinea pig sera suggested that similar to mouse serum, it can develop in response to toxin as an antigen, antibodies against toxin which are mostly directed against the fragment C portion. On the other hand. guinea pigs seem to respond to the toxoid as an antigen by producing antibodies to more than fragment C. (Abstract shortened by UMI.)

description: Efficient navigation through space encompasses the ability to maintain a representation of self-location relative to the external environment in real behavioral time. Beyond the here and now, recalling a past experience or imagining a future scenario can be rather rapid, but experienced as if it were occurring in real time. Interestingly, damage to the hippocampus or its interactions with the prefrontal cortex impairs navigational decisions, memory retrieval, and future planning. How could the hippocampal-prefrontal system flexibly support these distinct timescale functions? To investigate the underlying physiological mechanisms, we continuously tracked the same hippocampal and prefrontal ensembles in rats throughout learning of a spatial alternation task. We found flexible expression of neuronal sequences at multiple timescales in both regions, including slow behavioral-timescale sequences (~seconds), as well as two types of fast sequences (~100-200 ms) as theta sequences during online periods and replay sequences during offline periods. The focus of my dissertation was to characterize and assess the function roles of these sequences, and to consider how these multiple-timescale neural codes may function as neuronal substrates to link memory to navigational decisions.
description: This dissertation first examines hippocampal-prefrontal replay in awake versus sleep states, and further discusses our findings in the context of earlier studies towards a framework of how sleep and awake replay may work together to support learning and memory. Second, it investigates the learning dynamics of hippocampal-prefrontal replay, and how such dynamics contribute to different stages of learning to support our ability of retrospective evaluation and prospective planning. Third, it interrogates the functional roles of theta sequences in both the hippocampus and prefrontal cortex, and considers the idea of how replay and theta sequences may contribute to complementary parts of a coordinated mechanism for learning and memory. Finally, it provides a synthesis of these observations, and suggests that these multiple-timescale neural codes in the hippocampal-prefrontal system contribute to flexible use of memories for future planning during navigational decisions.
The Individual's Journey Toward a Fulfilling Sense of Judaism

description: What leads people to leave behind the communities that they grew up in and pursue a new lifestyle and Jewish observance? How is that discussed, and how do those who have been situated in their community for 10+ years talk about it versus those who are just beginning the process of finding new community? This paper examines how individuals talk about that moment in their lives and their experiences in the midst of going through the process. It further examines how they become members of their new, chosen communities through the frameworks of situated learning, legitimate peripheral participation, and communities of practice. These frameworks help to understand the effort that must be put in by individuals as they enter new spaces and seek to become legitimate members within their confines.

description: This thesis investigates Nicholas Love's negotiation of the social and religious tensions of early fifteenth-century England---caused by increasing lay literacy, the ongoing Wycliffite controversy, and the aftermath of the Lancastrian takeover---in the Mirror of the Blessed Life of Jesus Christ, his translation of the pseudo-Bonaventuran Meditationes vitae Christi. It demonstrates that although Love's Middle English translation extended the Meditationes to a broad lay readership, manuscripts of the Mirror circulating ever more widely as the fifteenth century progressed, the work was early associated with figures in positions of power, ranging from Archbishop Arundel, the leader of the orthodox suppression of Lollardy, to Thomas Beaufort, an extender of Lancastrian military power abroad, to Sibyl de Felton, the abbess of a prosperous and somewhat worldly convent, who might have used the Mirror to stir up orthodox zeal among her nuns. It is argued that despite these connections, the intentional conservatism with which Love condescends to his lay readers, and even the aggressive orthodoxy of the Treatise on the Sacrament, which is original to Love, this work is more than a piece of Church propaganda, for, retaining the Meditationes's emphasis on Christ's human relationships, it invites its readers to an intimate and emotionally charged encounter with Jesus, the divine human being who is both the instigator and the object of their devotion. Finally, it notes the paradox that in the Treatise on the Sacrament, which closes the work, Love incorporates material that is dramatically powerful but theologically problematic.

description: This research explores the intriguing socio-economic landscapes of Hamburg and Saint Petersburg, delving into the complex relationship between key macroeconomic variables and economic growth from 2016 to 2021. Focusing on the "second capitals" of Germany and Russia, the study examines the impact of Construction, Industrial Production, Services, Unemployment, and Salary Levels on economic output in both cities. Utilizing multiple regression analysis, the research reveals surprising similarities and divergences in underlying economic mechanisms, highlighting the often ambiguous and time-dependent influence of these factors. The analysis underscores the need for more transparent and uniform tracking of macroeconomic data on a high-frequency and regional level to better understand the dynamics of city-level economies.

description: The necessity for the industrial-scale conversion of renewable to also storable energy is the base from which this work arose. The thrive towards innovative, cheap, non-toxic and stable catalysts was the motivation to synthesize, characterize and apply a material the comprises only of the metal iron and bears the potential to produce molecular hydrogen from water efficiently and sustainably. The naturally-occurring mineral “green rust” of the fougèrite group lays the foundation to access a Fe3+-only material named mössbauerite that has been overlooked so far from many. The transient nature of the precursor green rust, the highly disordered layered structure and its flexibility regarding redox-activity, composition, and morphology make it an equally intriguing and frustrating material. In this regard, no previous work has collectively looked at the synthetic details, compositional and structural details, interlayer state, electronic properties or electrocatalytic properties.

description: Microbially induced calcite precipitation (MICP) using s.pasteurii demonstrates high plausibility. This research aimed to develop a lab-based “push-pull” injection system which improves treated soil’s homogeneity. Different injection methods and spacing had been studied using the “push-pull” mechanism on 444 mm x 278 mm x 150 mm sized samples.
Effluents were collected for pH and ammonium content analyses. Surface strength, surface calcite contents and core unconfined compressive strength were determined after curing.
One directional alternating diagonally injection method yielded the most homogenous strength sample without valley. Sample exhibits more than 4 MPa surface strength and 0.59 MPa core unconfined compressive strength.

description: La présente thèse a pour objectif d'améliorer notre compréhension des caractéristiques du comportement électoral des Franco-Ontariens. Tout en cherchant à palier à la rareté des études sur le sujet, notre thèse tente de déterminer les conditions présidant à l'existence d'un vote distinctement franco-ontarien aux élections législatives de la province de l'Ontario. Il s'agit d'une analyse longitudinale des résultats électoraux dans les circonscriptions électorales ayant au moins 30 p. cent de francophones dans le cadre des dix élections générales provinciales de 1971 à 2003. La comparaison de ces résultats avec ceux de l'ensemble de la province nous a permis de déceler à plusieurs reprises une volonté politique franco-ontarienne distincte, particulièrement acquise au Parti libéral et au Nouveau parti démocratique dans les régions de l'Est et du Nord-Est de la province. Toutefois, nous n'avons pas été en mesure de démontrer que le vote franco-ontarien était imputable au degré de francité des circonscriptions franco-ontariennes. Ainsi, cette thèse constitue un tremplin pour des études futures en vue d'approfondir cette appréciation des caractéristiques du comportement électoral franco-ontarien.

description: Due to persistent shortages of rehabilitation resources and services, collaboration tools for motion analysis have received great attention. High quality Internet connectivity and rich-content Web application platforms - Adobe Media Server and Flash Player, have created opportunities for integrating motion analysis into Flash based whiteboard and video conference applications to enhance rehabilitation services. For this thesis, clinical motion analysis software was created using Flash. The Motion Analysis Tools runs directly from a URL with a Web browser. The video synchronization procedure was supported by shared objects on a Flash Media Server. Program evaluation was conducted from accessibility and quality perspectives. Video synchronization error evaluation, angle and distance measurements, whiteboard functional, network latency impact, and ease of access were discussed during the evaluation phase. The Motion Analysis program can be access via Real-time Media Protocol (RTMP). A single TCP port was used for both signaling and media to maximize the chance of establishing a connection. Synchronization error was maintained at an acceptable level (maximum 160ms, average 49.3 ms, standard deviation 0.21). Average root mean square errors were 2.7 degrees for angle measures and 1.95 cm for length measures. The test results were consistent with video motion analysis results and within an acceptable range for rehabilitation motion analysis. This Web-based motion analysis approach provided an enhanced tool for quantitative motion analysis.

Sudden unexplained death

description: Sudden death in the young (SDY) is a public health issue that affects thousands of individuals in the United States annually. Both non-inherited and inherited causes of SDY have been identified, with the latter potentially putting surviving family members at risk of sudden death as well. Utilization of family history along with autopsy findings can lead to the identification of at-risk families who should have screening in order to identify other affected individuals. The SDY Case Registry was created to determine the incidence of sudden young deaths, better understand causes and risk factors, and inform ways to prevent these deaths. This is the first study from the Registry regarding site-specific processes for family history collection and recommendation of familial medical screening. This study investigates these processes among the SDY Case Registry through semi-structured interviews with nine individuals from seven sites. Questions explored these procedures, focusing on logistics, barriers, methods for combating barriers, and recommendations for improvements. Transcripts were coded and analyzed, and three themes emerged: (1) Variation between sites, (2) Barriers, and (3) Triggers of familial medical screening recommendations. Though there is variation in practice among the sites, many experienced the same barriers of (i) Timing and grief, (ii) Lack of family history in medical records, and (iv) Families lost to follow-up. Sites also had devised ways of combating these barriers by (iii) Utilizing other sources of information. This study provides insight into the inner workings of these processes across the SDY Case Registry and recommendations to improve prevention efforts for at-risk family members.

description: The 12.9 km Confederation Bridge, crossing the Northumberland Strait in eastern Canada, is one of the longest reinforced concrete bridges in the world. The bridge was designed for a service life of 100 years, which is twice the service life considered in the Canadian codes for highway bridges that were in use at the time. Much higher safety factors than those for typical highway bridges were used. In the design of the bridge, the seismic hazard was represented by a seismic design spectrum. This spectrum was derived by applying spectral amplification factors to the peak ground acceleration, velocity and displacement, corresponding to the design service life and the required safety of the bridge. The design forces and displacements due to seismic loads were computed using the response-spectrum analysis method. This thesis presents results from a seismic evaluation study of the Confederation Bridge. The following seismic excitations were considered in the study: (i) excitations represented by the uniform hazard spectrum for the bridge location, (ii) ground motion records representative of seismic motions in eastern Canada, (iii) ground motion records representative of seismic motions from large earthquakes at large distances, (iv) records obtained during the 1988 Saguenay, Quebec earthquake, (v) records obtained during the 1982 Miramichi, New Brunswick earthquake, and (vi) simulated seismic ground motions for the bridge location. The bending moments and displacements obtained from the seismic analysis were compared with the design values. It was found that the seismic parameters used in the design are quite representative of the seismic hazard of the bridge location. (Abstract shortened by UMI.)

description: The distinctive properties of graphene, characterized by its high carrier mobility and biocompatibility, have stimulated extreme scientific interest as a promising nanomaterial for future nanoelectronic applications. In particular, graphene-based transistors have been developed rapidly and are considered as an option for DNA sensing applications. Recent findings in the field of DNA biosensors have led to a renewed interest in the identification of genetic risk factors associated with complex human diseases for diagnosis of cancers or hereditary diseases. In this paper, an analytical model of graphene-based solution gated field effect transistors (SGFET) is proposed to constitute an important step towards development of DNA biosensors with high sensitivity and selectivity. Inspired by this fact, a novel strategy for a DNA sensor model with capability of single-nucleotide polymorphism detection is proposed and extensively explained. First of all, graphene-based DNA sensor model is optimized using particle swarm optimization algorithm. Based on the sensing mechanism of DNA sensors, detective parameters (Ids and Vgmin) are suggested to facilitate the decision making process. Finally, the behaviour of graphene-based SGFET is predicted in the presence of single-nucleotide polymorphism with an accuracy of more than 98% which guarantees the reliability of the optimized model for any application of the graphene-based DNA sensor. It is expected to achieve the rapid, quick and economical detection of DNA hybridization which could speed up the realization of the next generation of the homecare sensor system.

description: Delirium Tremens is a piece of new music composed for percussion, flute, piano, and electric bass. In composing this piece, I endeavored to find a way to convincingly integrate the electric bass into an otherwise traditional classical chamber ensemble of acoustic instruments. The bass is quite versatile, and the addition of amplification and electronics introduces another realm of possibility for this underused and underappreciated instrument; I set out to explore the tonal range and timbral breadth of the electric bass with alacrity. Utilizing the bass in its conventional role as a rhythm section instrument as well as exploiting it as a melodic counterpart with the rest of the ensemble allowed me to achieve my goal of seamless integration. This dual role allowed the bass to achieve timbral similarity and tonal clarity when necessary, blending into the music in a very natural way. Conversely, it also allowed for the idiosyncratic nature of the instrument to be showcased in a memorable fashion that was still musically and compositionally sound. I also paid particular attention to the use of natural harmonics on the bass in a melodic fashion, something relatively uncommon in this setting. The resulting music sounds organic and emblematic of the style while still retaining a unique component in the synthesis of chamber music and the electric bass.
Impacts of late-season soil and foliar nitrogen fertilizer supplements on wine grape yeast assimilable nitrogen (Yan) and canopy growth in Vitis vinifera L. Riesling

description: Nitrogen (N) application type and timing in Vitis vinifera L. wine grape production has been extensively studied in various grape growing regions and on countless cultivars. Due to the central role of N in vine growth and development, N status in the vineyard is carefully monitored and followed. Vines that are N deficient are provided with additional N to stimulate N metabolism and protein synthesis, but vines that have access to surplus N however, respond with excessive vegetative growth, which can lead to a reduction in yield, reduced fruit quality, and/or a hospitable environment for pests and diseases due to increased canopy density. Since wine grapes in central Washington are historically low in yeast assimilable nitrogen (YAN), the objective of this study was to evaluate the impact of supplemental post-véraison nitrogen (N) applications of organic or conventional sourced fertilizer, via soil and foliar, on irrigated 'Riesling' wine grape. In 2011 and 2012 N applications were made by either soil (simulated drip) or foliarly at the rates of 0, 17, or 34 kg/ha N in a commercial vineyard. Fruit was harvested within 2 days of commercial harvest from each plot and quality measurements taken included: yield, oBrix, TA, pH, average cluster weight, and cluster count. In addition, a subsample of fruit was collected for YAN and aromatic compound analysis. Small lot wines were made and fermentation rate was monitored. Soil NO3-N and tissue total N concentrations resulted in no evidence in treatment effects, but possible climatic effects between years. No indication of significant differences in canopy vigor resulting from N fertilizer applications could be found in 2011 or 2012, but many differences were found between years, which are possibly related to climatic differences. Results from 2011 indicate that foliar N applications and organic soil applied N, at 34 kg/ha N rate, increased YAN, but this did not hold true for 2012. Overall, differences between years are being attributed to climatic differences, and not from treatment effects.
Stories in the Sherds: A Typological Analysis of Indigenous North Carolina Ceramics

description: The Outer Banks of North Carolina are comprised of several islands that run alongside the mainland. These islands have access to estuaries and smaller bays, which host a rich marine habitat, thereby having a diverse collection of prehistoric to historic archaeological sites. One island is called Cape Creek, where many archaeology studies have found a vast number of Indigenous artifacts including thousands of pottery sherds, or pieces, which archaeologists have sorted into defined categories. This study focuses on pottery sherds from an excavation that took place from 2009 to 2017 by archaeologists from the University of Bristol. Using these previously documented categories, the research analyzes over 300 sherds from this recently-excavated assemblage, estimating their age and identifying the cultures that most likely created them. The results mostly match previous excavations, but new materials and decorations in the ceramics reveal previously undocumented complexities in the Indigenous communities who lived here long before European contact.

description: In this dissertation, I explore Liszt’s significance as author and music critic through an analysis of four of his series of character portraits from his Weimar period (1848-1861). In these writings, Liszt not only contributes to the mid-century debate over musical aesthetics on the side of the musical progressives (the New Germans), but he also effectively continues to promote his own musical values and aesthetics to his audience, many ideas of which he had introduced in earlier prose works. Through examination of Liszt’s essays on John Field, Clara Schumann, Robert Franz, and Pauline Viardot-Garcia, I illustrate how Liszt strives to achieve the overarching goal of his prose works: to educate the musical public (both contemporary and in the future) to recognize, support, and promote “true” musical artists and artistry. By deconstructing the talents of these well-known musical figures in his character portraits, Liszt explains to his reader why this specific artist should be venerated. Liszt is seldom viewed in music history as an influential writer, nor is the content of his literary works frequently examined in scholarship. Through my analysis of Liszt’s character portraits I will demonstrate his importance as a music critic, thus acknowledging Liszt’s significance in each facet of his life, of which his role as author is of integral importance.
title: A Cultural Analysis of Ageing: Baby Boomers and the Lived Experience of Extended Youthfulness
Creators: name: Brown, Neil Mackenzie
Publisher: name: Goldsmiths, University of London
Year: 2005

description: The thesis examines how contemporary members of the so-called baby boom generation (born between 1946-1964) in the UK, Ireland and North America present themselves in relation to ageing. Focusing upon the resources or categories they draw upon to do so, in an in-depth, semi-structured, interview situation. Much of the previous scholarly research into ageing has focused primarily upon issues relating to either social policy or demography, which, whilst being valid concerns, have tended to neglect broader cultural aspects relating to identity and representations of ageing. These representations currently serve to further distance middle from old age and death, reconfiguring the process of ageing around an extended period of youthfulness. This needs to be addressed, of which my research forms a part. Primarily by interrogating the production of aged subjectivities; to look for evidence of resistance to norms that construct ageing as an inevitable period of uniform decline; to demonstrate how this may be occurring and with what effects, such as for example, a paradoxical contribution to increased ageism. While people inevitably grow older physiologically, how these processes are understood are neither universal, nor 'natural'. Rather, they are historically specific and are conceived in particular societies in culturally specific practices, ideas and philosophies. I adopt a discursive approach to identity and ageing. Where the data is not treated as providing the 'answers' to questions of age and identity (Skeggs, 1997) but treated instead as material that requires further explanation and interpretation, and which is itself productive of aged/ageing identities. Viewed in this manner, close attention is paid to the variety of techniques through which the interviewees present themselves in relation to age. Such techniques include for example, the use of narrative, or the rhetorical use of notions of 'experience' or 'generation' as resources for the performance of (aged) identity (Scott, 1992).

A scheme for dynamic deployment of bandwidth in opto-electronic switches and agile optical networks

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2005
Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis investigates a novel scheme of Flexible Bandwidth Provision (FBP) in a three-stage packet switch. The proposed switch architecture is a hybrid optics/electronics Clos-like switch. The electronics domain is used as a memory technology, and the photonics domain is used as a communication technology. The architecture and method are suitable for the relatively slow reconfiguration of current transparent photonic switch technology. The advantage of including both optics and electronics implementation is that packets do not contend over resources, such as shared buses, that are not fundamental to a packet switch. The FBP algorithm is used to change the configuration of the optical centre stage to provide the bandwidth required by the incoming traffic. The switching performance generally constrains by either the data rate or the total port number of the switch. This thesis will then examine the mapping of FBP onto an Agile All-Photonic Network (AAPN). AAPN proposes an overlaid-star topology with edge-nodes interconnected by the beams of the stars via the core switches located at the hub of each star. The Adaptive Wavelength-Timeslot Allocation (AWTA) algorithm is introduced for the network to adapt the configuration of a core node to meet the demands of changing traffic patterns. If the algorithm is used over more than one core node, it may also provide an option to the edge nodes to choose distinct routes with different propagation delays, which can relieve the routing of delay-critical traffic. The results show that the queuing delay performance is directly proportional to the time between configurations of the core node and the links propagation delays.

description: Graphene, which as a new carbon material shows great potential for a range of applications because of its exceptional electronic and mechanical properties, becomes a matter of attention in these years. The use of graphene in nanoscale devices plays an important role in achieving more accurate and faster devices. Although there are lots of experimental studies in this area, there is a lack of analytical models. Quantum capacitance as one of the important properties of field effect transistors (FETs) is in our focus. The quantum capacitance of electrolyte-gated transistors (EGFETs) along with a relevant equivalent circuit is suggested in terms of Fermi velocity, carrier density, and fundamental physical quantities. The analytical model is compared with the experimental data and the mean absolute percentage error (MAPE) is calculated to be 11.82. In order to decrease the error, a new function of E composed of α and β parameters is suggested. In another attempt, the ant colony optimization (ACO) algorithm is implemented for optimization and development of an analytical model to obtain a more accurate capacitance model. To further confirm this viewpoint, based on the given results, the accuracy of the optimized model is more than 97% which is in an acceptable range of accuracy.

Subjects: subject: Political Science, General.

description: During World War II, the American foreign policy opinion elites conducted an intense debate in the popular and academic presses on the problem of how to treat the people of Germany. Taking place during a war conducted by a democracy against a totalitarian regime and coinciding with the introduction of scientific public opinion measurement, the debate emphasised American democratic ideology. The participants in the debate, from government officials to journalists, often constructed their arguments around national character theories which allowed them to proceed rapidly to the conclusion that the whole German people bore the blame for the war. On this basis these commentators outlined plans to both permanently curb German aggression and to bring democracy to Germany. These developments fostered impractical public expectations for foreign policy achievements and drove the public debate on the German problem to extremes which found their way into policy planning. These extremes precipitated an elitist reaction that presaged the development of the postwar realist approach to foreign policy, including its emphasis on planning by experts and its concomitant dismissal of mass public opinion. This approach is apparent in the pollsters' wartime analyses of mass public opinion on the German question.

description: The Naegleria genus encompasses a remarkable amount of diversity such that analyzing the delineation of species within the genus using genomic data is incredibly informative. Naegleria species cannot be completely defined on the basis of morphology or sexual
description: reproduction, and thus it is necessary to rely on DNA sequence comparisons for observing species boundaries. For several years, sequences from the ribosomal plasmid gene ITS (internal transcribed spacer) have been used to define Naegleria species. Overall, a portion of the mitochondrial gene CO1 (cytochrome c oxidase I) is widely used to define and ‘barcode’ species. The goal of this study was to first determine whether there would be consilience (agreement) between the ITS and CO1 phylogenetic trees in terms of whether the same strains would group with the same species between the different gene trees. Despite the fact that certain species clusters were not always in the same location between the ITS and CO1 trees, consilience was achieved between the ITS and CO1 Maximum Likelihood phylogenetic trees such that the same strains always clustered together to create the same species groupings. This consilience indicates that either DNA sequence provides a useful way to examine Naegleria species. Moreover, in comparing both the within- and between-species sequence variation for both ITS and CO1 gene sequences, the range of sequence variation that existed for each gene was achieved here. In general, greater within-species sequence variation existed with CO1 sequences than with ITS sequences, but there was a greater amount of between-species sequence variation with ITS sequences than with CO1 sequences. Finally, the diversity of species found in a small micro-environment (a birdbath) was examined. Overall, the results of this study indicate that there are many more species in the Naegleria genus than were anticipated a few years ago, but the results also leave open numerous questions about species delineation in molecular species such as Naegleria, especially when considering the worldwide distribution of Naegleria species.

description: Within the profession of nursing, reflective journal writing is enthusiastically endorsed as an essential pedagogical strategy for producing reflective practitioners. Despite a lack of empirical evidence to substantiate the claims associated with reflective journaling, the prevailing belief in contemporary nursing education reflects an assumption that this practice is essential in the production of critically engaged nurses. This has resulted in a totalizing discourse that presents the adoption of reflective journaling within nursing curricula as unproblematic. This study combines the methodological principles of grounded theory, along with a poststructuralist approach, to explore the experience of reflective journaling from the perspective of university nursing students. Application of a Foucauldian analysis demonstrates how assumptions related to the utility of reflective journal writing are embedded within a variety of powerful discourses that shape how we think and speak about this practice. Of particular relevance is Foucault's exploration of the impact of surveillance, observation and disciplinary power. Reflective journaling is identified as a ritual of confession that produces self-regulating and compliant students. This study reveals that journal writing is largely viewed as a prescribed activity and assumptions are made by nurse educators regarding the ability of journals to facilitate critical reflection. The discourses that emerged from this analysis reflect different aspects of the socialization process that ultimately results in the construction of an "authentic" nurse. In closing, students and nurse educators are encouraged to develop alternative discourses that challenge the uncritical acceptance of reflective journal writing within contemporary nursing education.

description: Like many rivers around the world, the Rideau River is under pressure from a number of human induced activities resulting in a loss of species and habitat. In order to prioritise conservation efforts, it is necessary to understand what type of habitats will support the widest range of species. This study examines which physical and chemical factors exert the strongest influence on the diversity and community composition of aquatic macrophytes in the Rideau River. Macrophyte species were surveyed at 33 sites on the Rideau River, Ontario, in six 1 m2 quadrats aligned in a belt transect perpendicular to shore along a depth gradient of 0.5 m to 2.0 m. Regression analysis showed species richness and Shannon diversity were significantly related to water velocity, transect length, slope, and organic content. Multiple regression provided a model whereby 70% of species richness was explained by organic content, transect length, water velocity and chlorophyll a, and 77% of Shannon diversity was explained by organic content and water velocity. Mantel tests showed only chlorophyll a was weakly correlated with species composition. Canonical correlation analysis showed floating and floating-leaved species to favour habitats with low water velocity. No other significant patterns were found. It appears that while species diversity can be predicted from physical environmental variables, species composition cannot.

description: In recent years, we have witnessed a growing interest in the synchronous collaboration based class of applications. Several techniques for Collaborative Virtual Environments (CVE) and Collaborative Haptic, Audio and Visual Environments (C-HAVE) have been designed. However, several challenging issues remain to be resolved before CVE and C-HAVE technologies become a common place. In this thesis, we focus on applications that are based on closely coupled and highly synchronized haptic tasks that require a high-level of coordination among the participants. Four main protocols have been designed, in the literature, to resolve the synchronization issues in collaborative virtual environments: the Synchronous Collaboration Transport Protocol (SCTP), the Selective Reliable Transmission Protocol (SRTP), the Reliable Multicast Transport Protocol (RMTP) and the Scalable Reliable Multicast (SRM). However, none of these protocols has been able to meet all of the basic CVE requirements, i.e., scalability, reliability, synchronization, and minimum delay. In this thesis, we propose a hybrid multicast transport protocol, which we refer to as HMTP that aims at meeting the CVE requirements. We describe our protocol, discuss its implementation and report on the performance results we have obtained for two virtual tele-surgery training class of applications.

description: Part I. The development and mechanistic study of a biomimetic decarboxylative aldol reaction. A reaction has been developed in which malonic acid half thioesters (MAHTs) and malonic acid half oxyesters (MAHOs) are shown to undergo decarboxylative nucleophilic addition reactions with ketone and aldehyde electrophiles under exceptionally mild conditions. In the presence of Et3N at room temperature in THF, various nucleophile and electrophile analogues form beta3-hydroxyester and thioester products in moderate to good yields. It is also demonstrated spectroscopically that these decarboxylative aldol reactions proceed through a post-addition, pre-decarboxylation intermediate. The formation of this intermediate is shown to be reversible using both experimental and kinetic means of analysis. The rate constants for intermediate formation and decomposition to product in various solvents have been calculated using two different models and calculation methods. Part II. Ruthenium-catalyzed dehydrogenation of ammonia-boranes. The dehydrogenation of ammonia-borane (AB) and methylammonia-borane (MeAB) is shown to be catalyzed by several Ru-amido complexes. Up to one equivalent H2 (1.0 system wt %) is released from AB by as little as 0.03 mol % Ru within 5 minutes, and up to two equivalents H2 (3.0 system wt %) are released from MeAB with 0.5 mol % Ru in under 10 minutes at room temperature, the first equivalent emerging within 10 seconds. Also, a mixture of AB/MeAB yields up to 3.6 system wt % H2 within 1 hour with 0.1 mol % Ru. Several catalytic analogues were synthesized to evaluate the active species the catalytic cycle, and computational studies were performed to elucidate the mechanism of dehydrogenation of AB. Finally, it was shown that alkylamine-boranes can serve as a source of H2 in the Ru-catalyzed reduction of ketones and imines.
