description: Using an online survey with randomisation, we illustrate how identity-based utility can be harnessed to encourage pro-environmental behaviours. Results show that providing farmers with an opportunity to demonstrate their ‘green credentials’ increases their intention of maintaining environmental practices by an average of 19%, while the use of descriptive norms increases intent to participate in a biodiversity activity by an average of 8%. Interventions such as these represent a low-cost, yet powerful supplement to traditional policy tools. New approaches for engendering behavioural change are likely to be particularly important in a UK context as the UK transitions out of the EU.
Laboratory ADCP bedload measurements: Comparison with capture rates and dune tracking
Creators: name: Ramooz, Rauf

Subjects: subject: Engineering, Civil.

description: Moving bottom bias in acoustic Doppler current profiler (ADCP) bottom tracking has been used as an estimate of apparent bedload velocity (Rennie et al., 2002). However, it remains unknown if the apparent bedload velocity is an unbiased estimate of average bedload particle velocity. This paper presents a controlled laboratory calibration of ADCP bedload velocity, which was performed in the Main Test Channel at the St. Anthony Falls Laboratory as part of the National Centre for Earth-Surface Dynamics SedT project. The length of the sediment-recirculating mobile bed test section was 20 m. Both sand-bed (d50 = 0.98 mm) and gravel-bed (d50 = 11.06 mm) bedload transport experiments were conducted, with five flow rates tested for each sediment. Bottom track data were collected with both 600 and 1200 kHz Rio Grande ADCPs, and over a range of bottom track pulse lengths (&R20 to &R40). Actual bedload transport rates were measured using (1) conventional samplers, (2) five automatic weigh pans spread across the channel at the end of the test section, (3) dune tracking by means of eight sonars, and (4) high speed digital videography. In this paper, measured apparent bedload velocity is compared to bedload transport rate from the weigh pans and dune tracking. In addition, the influence of bottom track pulse length and operating frequency on measured bedload velocity is assessed. The results show correlation between ADCP bottom tracking and measured bedload transport rates, with coefficient of determination (r 2) ranging from 0.59 to 0.93 with RMSE (root mean square error) ranging from 0.059 m/s to 0.106 m/s for sand bed. For the gravel bed, correlation was found between capture rates and dune tracking with r2 0.52 to 0.97; however, the results were scattered. Initial experimental test results verified that moving bottom bias in acoustic Doppler current profiler (ADCP) bottom tracking can be used as an estimate of bedload velocity. A comparison was achieved successfully with measured flux of capture rates and dune tracking transport rates. The preliminary results were promising for sand bed experiments; however for gravel bed it appears that the flow depths were insufficient for the operation of ADCP.
RNA processing of the ccmFn-rps1 and rpl5-Psirps14-cox3 loci in wheat mitochondria during seedling development

description: Plant mitochondria possess a gene expression system in which post-transcriptional events, such as transcript end maturation and turnover mechanisms play a key role in regulating the transcriptome. In addition, during early developmental stages of embryo germination, differing transcript profiles have been seen. This research focuses on two loci in wheat mitochondria, ccmFn-rps1 and rpl5-Psirps14-cox3, to elucidate the transcription and post-transcriptional events involved in their expression. Northern analysis of the ccmFN-rps1 genes during early seed-to-seedling development reveals a 3.2 kb primary transcript and a 2.7 kb bicistronic mRNA. A 0.7 kb monocistronic rps1 mRNA is detectable up to 2d but there is no detectable monocistronic ccmFN transcript during the stages examined. Transcript ends were mapped using circular-RT-PCR and phosphatase treatment at three different developmental stages and revealed two processing sites as well as a single 3' end common to all three transcripts. The 5' ends of the processed rps1 transcripts are heterogeneous and do not always include the start codon, questioning the rps1 transcript functionality. Gene order varies between plant species due to the high recombination rate in mitochondrial genomes, as is seen for rpl5-Psirps14 in wheat and rice. In both plants, the functional rps14 gene is encoded in the nucleus and the mitochondrial rps14 copy is a pseudogene. In wheat, rpl5-Psirps14 are co-transcribed with cox3 as two RNA species of 3.5 kb and 2.7 kb at 24hr post-imbibition and exhibit developmentally-specific differences in abundance in seedlings. Two promoter regions were mapped in wheat upstream of rpl5 and both transcripts have the same 3' end. In rice 24hr and 6d however, rpl5-Psirps14 are co-transcribed as a 1.4 kb bicistronic mRNA. This presumably reflects the different regulatory signals used in different species. In addition, rpl5 has been subject to several independent gene transfers to the nucleus in the cereal lineages. For example, there is a functional copy of rpl5 in the mitochondria and the nucleus in wheat but it is absent from the mitochondria in rye and maize. In oat mitochondria, rpl5 appears to be a pseudogene and in barley, rearrangements at the 3' end and low transcript levels question its functionality. The characterization of transcription initiation sites, processing sites and 3' ends for these two loci reflect the relaxed nature and flexibility of signals exploited by plant mitochondria. This research supports the significant role of post-transcriptional events in the regulation of gene expression in plant mitochondria.

Habitat use and movement patterns of juvenile black ratsnakes (Elaphe obsoleta) and their conservation implications

description: The central goal of this study was to describe the habitat use and movement patterns of juvenile black ratsnakes and contrast them to those of adults to identify any ontogenetic changes that should be included in the management plan of the species. My results indicated a clear ontogenetic shift in the movement patterns and spatial ecology of black ratsnakes. I found that daily and seasonal movements, home range size and fidelity, behaviour, and fidelity to over-wintering sites all vary with size. The results suggested that juvenile black ratsnakes, especially males, may be in a dispersal stage. If juveniles are playing a significant role in maintaining gene flow through dispersal, then adequate protection requires sufficient protected habitat to allow juvenile dispersal. I also showed that juveniles rarely attend communal hibernacula and often switch between hibernacula. Therefore, habitat to be protected cannot simply be defined as a fixed radius around a communal hibernaculum because many juveniles do not attend these communal hibernacula. This study reinforces the importance of understanding ontogenetic changes in the ecology of species of conservation concern. Insight into an ontogenetic shift in habitat use would be essential for sound management of any species where juveniles have more specific structural needs than adults, due to intense predation risk, specific prey requirements, etc. Ontogenetic shifts in movement patterns and spatial ecology have to be considered in management decisions.

description: Australians have adopted wireless broadband with fervor. People can be seen sitting over their morning coffee reading the screen on their mobile phone, or hunched over their laptop in cafes all around the country. This paper explores from a social perspective the behaviours of a particular group of end users who through their use of wireless broadband and mobile devices continue to work anytime and anywhere. In contrast to the telecommuters of the early 1990s who worked from home, this group of end users known as Mobile Knowledge Workers or more generically as mobile workers continue to work away from the workplace but not necessarily in a fixed location such as home. Mobile Knowledge Workers continue to conduct work across a range of locations and rely on their wireless broadband to perform tasks and to keep connected with the office. The results of an online questionnaire demonstrated that through the use of wireless broadband and a range of mobile devices such as laptops, smart-phones, and tablets, Mobile Knowledge Workers continue to productively perform a range of tasks across a number of different locations.

The effects of running-induced neuronal activation on the plastic expression of mouse cerebral GLUTI
Creators: name: Allen, Angela
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Psychology, General.

description: Glucose, the predominant energy substrate of the central and peripheral nervous system, is delivered to neurons via a family of facilitative glucose transporters (GLUTs). The majority of glucose is transported to the brain via GLUT1 located at the blood-brain barrier. Several types of memory and learning tasks leading to changes in neuronal activity have also been linked to increases in glucose demand and local cerebral glucose utilization (LCGU). Current research has indicated a corresponding change in GLUT1 expression in response to increased metabolic demand in operant tasks. However, concomitant neuronal structural plasticity has not been currently investigated. In addition to operant learning tasks, voluntary running has also been identified as a source of neuronal activation. The purpose of this study is to examine the effects of neuronal activation induced by voluntary running on the plastic expression of GLUT1 and the concomitant remodeling of neurons in the mouse brain.
Ribosomes of moderately halophilic bacteria.

Subjects: subject: Biology, Animal Physiology.

description: The ribosomes of Vibrio costicola were stable over a wide range of salt concentrations. Sucrose gradient profiles of ribosomes from cells grown in different salt concentrations and isolated in various salt concentrations were similar. The sedimentation coefficients of the ribosomal particles were 64, 48, and 28 S for the monosome, large subunit, and small subunit, respectively. These values were not altered by the NaCl concentration of the growth medium nor by the salt concentration of the isolation buffer. There was, however, slight evidence that higher salt concentrations were removing some of the ribosomal proteins. The total ribosomal proteins were found to be more acidic (B/A = 1.08) than the total ribosomal proteins of E. coli (B/A = 1.58) but less acidic than the total ribosomal proteins of H. cutirubrum (B/A = 0.69). The relative acidity of the total ribosomal proteins was not changed by the NaCl concentration the growth medium. Two ribosomal proteins equivalent to the E. coli S1 and L7/12 were purified and the partial amino acid sequence of the latter was determined. The V. costicola protein was 79% homologous with the E. coli protein and 74% homologous with an equivalent protein from the unclassified moderate halophile, H.x. The average hydrophobicity of the V. costicola total and purified ribosomal proteins were not significantly different than those of E. coli. An in vitro protein synthesizing system was developed for V. costicola. The in vitro system was energy dependent and sensitive to inhibitors of protein synthesis. The poly-uridylic acid dependent system incorporated phenylalanine into oligophenylalanines. The in vitro system directed by poly-U had a salt optimum of 0.15 M with greater activity in NH4Cl than KCl which had greater activity than NaCl. The magnesium optimum was approximately 18 mM. The in vitro system directed by "endogenous" messenger had similar salt response as the poly-U system except that NaCl was inhibitory at all concentrations. Increasing the salt concentration above the optimum increased the misreading of the poly-U message. The in vitro protein synthesizing system was stable for at least 8 hours in 1.0 M NaCl, KCl, or NH4Cl. The ribosomes and protein synthesizing system demonstrated considerable salt stability. The low salt optimum of the protein synthesis system and previously studied V. costicola enzymes and the effects of salts on misreading of poly-U suggest that the distribution of ions measured as intracellular may not be uniform throughout the cell. The envelope of the cell may bind large amounts of these ions leaving the cytoplasm with a relatively low "free" ion concentration.

description: Background Many parasites (protozoa and helminths) can be transmitted through food and lead to infections with high morbidity, as well as disease outbreaks. Although the importance of foodborne parasites (FBP) is recognised by many sectors of the food industry, standardized analytical methods and validation procedures for testing food for FBP are lacking. Scope and approach:Current methods for detection of FBP, and their validation, are critically reviewed, focusing on priority FBP in Europe: the helminths Echinococcus multilocularis, Echinococcus granulosus, Taenia saginata, Trichinella spp., and Anisakidae, and the protozoa Toxoplasma gondii, Cryptosporidium spp., and Giardia duodenalis. Key findings and conclusions:Standard methods exist for detection of T. saginata in beef, and Trichinella spp. in meat (and are mandatory at meat inspection in Europe), Anisakidae in fish, and Cryptosporidium spp. and G. duodenalis in leafy green vegetables and berry fruits. For other FBP or foods, methods used in sample surveys have been described, but validation data are generally absent; limits of detection are not provided, ring trials have rarely been performed, and for most FBP quality control materials, proficiency schemes, and reference standards are lacking. The use of surrogate particles or organisms for method development or validation purposes needs to be carefully considered. Documented procedures for validation, such as ISO17468 and ISO16140-2:2016 that were established for bacteria, are mostly inappropriate for FBP. The development and application of standardized and validated detection methods would enhance understanding of the foodborne route of transmission, improve risk assessments, and help identify and verify critical control points.

Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis presents a study on the biomagnetic response of the lobster nerve. Experiments have been made on the circumesophageal connective of the lobster in order to investigate the influence of a constant intense magnetic field upon (i) the nerve impulse conduction velocity of the entire trunk by recording the compound action potentials, and (ii) the membrane potentials and the transmembrane currents under voltage-clamp conditions of the giant axon of this nerve, using the double sucrose gap technique. It was found that within the limitations of these exploratory experiments the conduction velocity, the membrane potentials and the transmembrane currents of the lobster nerve are not affected in any detectable manner by a constant 1.2 T magnetic field parallel or perpendicular to the nerve.

Material surface chemistry influences the differentiation of human macrophages and their degradative and inflammatory response
Creators: name: Dinnes, Donna Lee M
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Chemistry, Biochemistry.

description: Numerous medical devices are comprised partially or completely of polyurethane (PU) materials, used as a result of their flexible, segmented structure, tensile strength and relative biocompatibility. The polycarbonate-based PU (PCNU), has been incorporated in the use of many devices as a result of their enhanced resistance to oxidative and hydrolytic degradation. Although relatively biocompatible, these materials still are sensitive to hydrolytic degradation and attachment of inflammatory cell types. Monocyte-derived macrophages (MDM) have been found as the primary cell type to adhere and remain at the cell-material interface of long-term implant devices. Although efforts are continually targeting the modification and design of improved PCNUs, cellular responses and MDM-mediated degradation of PCNU materials are not completely understood. The participation of inflammatory phospholipase A2 (PLA2) pathways were investigated for their participation in mechanisms leading to PCNU degradation by macrophages. Moreover, the influence of these materials on the stimulation of PLA2 pathways and the hydrolysis product, arachidonic acid, was further explored. Fully differentiated human MDM have been typically used for subsequent studies evaluating PCNU degradation, however, studies here were the first to examine the morphology and function of monocytes differentiating along the macrophage lineage under the influence of altered material surface chemistry. Finally, the tools of proteomics were employed here for the first time in the investigation of material surface influence on both the differentiation of MDM and in assessments of degradative capacity of MDM adherent to PCNU. The results presented here in this collection of manuscripts has provided evidence that PCNU materials induce changes in expression and activation of PLA2 enzymes, that in turn may have indirect participation in the mechanisms of degradation. In addition, the material surface upon which MDM differentiate, greatly influences not only cellular morphology but also function in terms of degradative capacity and cytoskeletal protein expression and rearrangement of actin-based structures. Proteomics techniques have identified proteins that may link contributors to the multi-factorial foreign body response to PCNU materials in vitro, involving PLA2 and the structural proteins actin, vinculin and vimentin that would ultimately lead to the release of hydrolytic enzymes that contribute to material breakdown. The understanding of these cellular responses and mechanisms of material destruction is an essential base of knowledge required for efficient design of medical implant materials for their intended use.

description: Objective We describe epidemiological trends of human brucellosis in Germany over a 13 year period based on national surveillance data. Methods We analyzed demographic, clinical, laboratory and exposure information of symptomatic laboratory-confirmed brucellosis cases notified 2006–18. Using official population data, we calculated incidences and risk ratios (RR). Results From 2006 to 2018, 408 brucellosis cases were notified in Germany (mean annual incidence: 0.38/1,000,000 population), of which 75% were travel-associated. Yearly notifications peaked in 2014 (n = 47) and remained elevated compared to 2006–2013 (mean: n = 25). Asylum seekers (AS) arriving in Germany accounted for 9/44 (2015) and 15/36 (2016) cases, respectively. RR AS/non-AS 2015–2016: 28, 95% CI: 17–45. Unpasteurized milk products were most frequently notified as source of infection. Imported food and occupational exposure played a role in autochthonous cases. Conclusions The incidence of human brucellosis has markedly increased in recent years. Most of the observed rise in notifications can be explained by infections in AS. Exposure still predominantly occurs abroad. Risk factors for autochthonous infections need to be investigated further, though imported dairy products seem to play a role. Physicians should consider brucellosis as differential diagnosis in AS and people with travel to endemic regions with compatible symptoms.

description: Background: The Government of Kenya is making plans to implement a social health insurance program by transforming the National Hospital Insurance Fund (NHIF) into a universal health coverage program. The objective of this study was to examine the determinants associated with health insurance ownership among women in Kenya. Methods Data came from the 2008–09 Kenya Demographic and Health Survey, a nationally representative survey. The sample comprised 8,435 women aged 15–49 years. Descriptive statistics and multivariable logistic regression analysis were used to describe the characteristics of the sample and to identify factors associated with health insurance ownership. Results Being employed in the formal sector, being married, exposure to the mass media, having secondary education or higher, residing in households in the middle or rich wealth index categories and residing in a female-headed household were associated with having health insurance. However, region of residence was associated with a lower likelihood of having insurance coverage. Women residing in Central (OR = 0.4; p < 0.01) and North Eastern (OR = 0.1; p < 0.5) provinces were less likely to be insured compared to their counterparts in Nairobi province. Conclusions As the Kenyan government transforms the NHIF into a universal health program, it is important to implement a program that will increase equity and access to health care services among the poor and vulnerable groups.
Constitution over convenience: Reaffirming the Labour Conventions rule on the application of the division of powers to international treaty implementation
Creators: name: Anderson, Pamela Louise
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: History, Canadian.
subject: Law.

description: This thesis calls for the reaffirmation of the Labour Conventions rule, which holds that the authority to legislate in implementation of international treaties follows the division of powers as laid out in sections 91 and 92 of the Constitution Act, 1867. It argues that the criticism that has plagued the rule since its inception has neglected constitutional considerations in favour of an assertion that a federal treaty-implementation authority is necessary for reasons of international expedience. It contends that this assertion is irrelevant in the absence of evidence that such international considerations are themselves constitutionally mandated, as constitutionalism is not trumped by convenience. To this end, it maintains that neither established principles of constitutional interpretation nor the supposed intentions of the Fathers of Confederation provide grounds for ignoring one of the fundamental tenets of the division of powers, that one level of government cannot unilaterally usurp the other's authority.
Impact of multipath angular distribution on performance of MIMO systems

Subjects: subject: Engineering, Electronics and Electrical.

description: The objective of this thesis is to analyze the impact of multipath angular distribution on the channel correlation and performance of MIMO systems. A full breadth of AOA models is used in this study, and they cover most scattering scenarios of the physical propagation channel. Closed-form expressions for parameters and corresponding correlations of these AOA models are derived. A simulation model was developed and extensive Monte Carlo simulations were performed to obtain the MIMO channel capacity, correlation, and diversity gain for various scenarios. Two major results are (i) the distributions shape has minor impact on the correlation, capacity and diversity gain; the major impact is due to the angular spread; (ii) the continuous and impulsive distributions have dramatically different impacts on the correlation, capacity and diversity gain.
Modelling of particle pyrolysis in a packed bed combustor
Creators: name: Tuck, Arden R. C
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Engineering, Chemical.

description: The combustion process of a dry wood particle within a packed bed combustor starts with the heat up and devolatilization of the wood to form char which then travels down through the reduction and oxidation zones to complete the combustion process. This thesis describes the development of a computational model for overfeed packed bed combustion of wood and other biomass fuels, including the modelling and tracking of individual particles within the devolatilization region of the bed. It builds on an earlier continuum bed model, with no description of processes within individual particles. A numerical model for the heat-up and pyrolysis of an individual particle is developed and numerically tested to determine the preferred grid sizing, time step (Deltat) and node number. The impact of particle density, size, the heat of pyrolysis and kinetics on devolatilization are studied. The particle model is then incorporated into the overall bed model by developing a mechanism for particle tracking in the devolatilization region of the bed, coupled with interpolation processes to transfer information between the bed and the particles. The resultant model shows that the model not only produces more detail about particle processes in the combustor but also produces profiles that compare well to the Girgis (2004) experimental data.
Design of a composite SMA actuator for a pressurized hyper-redundant manipulator
Creators: name: Lanteigne, Eric
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2006
Subjects: subject: Engineering, Mechanical.

description: Hyper-redundant devices are characterized by repeating independently controlled structures connected in series, much like the architecture of a snake or worm. This thesis evaluates the performance of a pressurized hyper-redundant manipulator design driven by high strain shape memory alloy actuators. The proposed design is composed of four identical modules; each providing three degrees of freedom from three symmetrically positioned actuators. The modules have an outer diameter of 31mm and a length of 33mm at full extension. The actuator return force and manipulator stiffness are controlled by an air pump connected at the base. Although connection failures between the actuator tabs and vertebrae prevented the validation of the hyper-redundant manipulator prototype, the unit module element was successfully fabricated and evaluated. The unit module could achieve linear contractions of 40% and rotations of over 50° at a frequency of 0.05Hz. Several limitations remain to be addressed in order to build a reliable device; these include: (1) The high current requirement of the actuators, (2) The inefficient actuation system, and (3) The connectivity issues between the actuators and the modules.
Estrogen regulation of the human 5-HT1A receptor gene
Creators: name: Cockburn, Amanda M
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2004
Subjects: subject: Biology, Neuroscience.

description: Altered regulation of the 5-HT1A receptor is implicated in depression. Since depression is twice as prevalent in women versus men and major hormonal events in women trigger depression, I evaluated estrogen regulation of the 5-HT1A receptor in rat RN46A raphe cells. Estrogen (100 nM) induced no change in transcriptional activity of the 5-HT1A promoter (-1515bp/ATG). A putative estrogen response element (1AERE, -433bp) was identified in human and mouse but not rat 5-HT1A promoter. At least one nuclear protein complex from RN46A cells expressing estrogen receptor (ERbeta) bound specifically to the 1AERE, which mediated estrogen repression that was blocked upon mutational inactivation of 1AERE. Mutation of 1AERE derepressed the human 5-HT1A promoter but, paradoxically, estrogen induced rat 5-HT1A RNA in RN46A cells. Thus estrogen, via ERbeta action at 1AERE, represses human 5-HT1A promoter activity, but has an opposite effect on rat 5-HT1A expression that could reflect species-specific or post-transcriptional regulation.
Simulation of blood flow in a ventricular assist device with fluid-structure interaction effects

description: Numerical simulations combining solid and fluid models and fluid-structure interaction effects were performed for a diaphragm-type ventricular assist device (VAD). These simulations include an open loop configuration, in which the VAD inlet and outlet tubes are open to the surroundings, and a closed loop configuration, in which the VAD is connected to an idealized model of the circulatory system. Comparisons have been made between the open loop case and previous experimental and numerical results for a similar VAD designed by a group at Brunel University. Differences between the two models can be partially accounted for by differences in flow forcing. Even with these differences, this comparison validates this method as a tool for the design and optimization of VADs. For the closed loop case, results were limited by the required use of a slightly compressible fluid model. Further relaxation of this requirement is needed to fully explore closed loop simulations.
Cause-effect validation of requirements for distributed systems.
Creators: name: Nursimulu, Khenaidoo.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1994
Subjects: subject: Computer Science.

description: In this thesis we propose a requirement validation technique based on the Cause-Effect Graphing (CEG) technique. Originally, the CEG technique, proposed by Elmendorf (Elme73) as a black-box testing technique, was used to derive test cases from an informal specification to test the corresponding implementation. The test cases obtained from this method are correct only if the requirements are correct in the first place. Therefore, a technique is required to validate the requirements themselves. The key contribution of this thesis is a framework and methodology for employing the Cause-Effect Graphing approach as a technique for validation of specifications especially in the context of distributed systems. This technique has also been extended to apply to distributed software. The extension has given rise to the Extended Cause-Effect Graphing (ECEG) technique where we use scenarios as an effective means of checking network behaviors against customer expectations. Our ECEG approach has been validated by case studies of telephony features. In these case studies, we give some examples of instances of undesirable scenarios, such as feature interactions, which were derived directly from customer specifications, thus demonstrating that major problems in requirements definitions can be detected and corrected even before software design begins. This validation approach is based on heuristics which in turn are based on a limited survey of the practices in the application domain. A key benefit of this approach is that scenarios can be derived automatically from the CEG based on path sensitization, an idea borrowed from the world of Integrated Circuits verification methods. A tool prototype has also been developed on the Macintosh and Sun Workstation environments.

Subjects: subject: Health Sciences, Recreation.

description: The purpose of this study was to explore the mental skill used by top taekwondo athletes and to determine how well Orlick's "Wheel of Human Excellence" (1995) could be applied to these athletes. In-depth interviews were conducted with nine Canadian taekwondo athletes who had completed and won medals at the international level. The results indicated that Orlick's element of commitment, belief, full focus, positive images, mental readiness, distraction control and, constructive evaluation were common to all subjects. The presentation of rich quotes and experiences offer valuable insights and strategies for taekwondo athletes. A survey of the mental skills of Canadian taekwondo athletes was also completed by 29 athletes to determine the importance of each of the mental skills indentified in Orlick's model.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Exploring word and sentence similarity in corpus

description: This research addresses the problem of deriving semantic similarity between words of language using corpora and contextual distributions comparison methods. It aims to capture, in a comprehensive way, the similar behavior of words and henceforth properly estimates the semantic similarity between words of the language. The framework proposed for this purpose is incremental and iterative. The system combines the Edit distance and the incremental results as a way for accurate similarity measure. Moreover, a sentence similarity system is developed on top of the word similarity model. Naturally, the proposed model rests on observing the words behavior in large amount of natural text. As for the strategy followed in this thesis, we first examine existing similarity measures, their hypotheses and show how these measures unfortunately fail to account for some linguistic features for estimating words similarity when they come under fine scrutiny. Furthermore, we present a model to enhance these measures to take into account linguistic characteristics. Indeed, the suggested model takes large amount of raw data as input, extracts distributions of contexts and infers accordingly similarity between words using these distributions and Normalized Edit distance (NED).

Purls for peace: The Voice of Women, maternal feminism, and the knitting project for Vietnamese children

description: In the fall of 1966, the Voice of Women, a Canadian-based, women's peace organization began participating in a humanitarian aid project to provide clothing for the victims of the Vietnam War. The intention of the project, began by another Canadian organization, the Canadian Aid for Vietnam Civilians, was to provide hand-made clothing and blankets to those most defenseless to the atrocities of the war: namely, Vietnamese children. What resulted was an assistance program to which the Voice of Women would dedicate more than ten years of its efforts and which would create a resurgence in an organization that had recently been shaken by several damaging events. What appeared to be simply women providing assistance to children in need was in fact an example of the result of maternal feminism at work. Not only did members of the Voice of Women utilize their roles and instincts as women and mothers to gain support from others for the knitting project; they also use these same roles and instincts as a means to make a strong political statement regarding the Vietnam War. This study will examine the mean by which the Voice of Women gained a great deal of support from both Canadian and American women. Likewise, it will analyze the role that maternal feminism played in the organization of a project that would prove to be a highly political and controversial endeavor.
An experimental study of natural convection in vertical open-ended concentric and eccentric annuli

description: The effects of eccentricity on the natural convection heat transfer from a vertical open-ended cylindrical annulus with diameter ratio of 1.63 and aspect ratio of 18:1 have been investigated experimentally. Measurements of transient and steady state wall temperature distributions for different eccentricities were collected to help understand the heat transfer processes and also to serve as benchmarks for the validation of future CFD studies. Particle image velocimetry was used to validate the calculated mass flow rate in the annulus. It was found that, whereas at very low eccentricities there was insensitivity to eccentricity on the overall heat transfer, a diminishing of the heat transfer occurred for higher eccentricities. Plots of the local azimuthal variation of the Nusselt number showed that at low eccentricities heat transfer improved on one side of the annulus but decreased on the other side. The Nusselt number was found to decrease with eccentricity, while the Rayleigh and Grashof numbers had an increasing trend. It was also found that the mass flow rate did not appear to be strongly influenced by varying eccentricity within the experimental range. The Reynolds number was calculated and the flow within the annulus was found to be transitional nearing laminar with increased distance from the inlet.
L'émergence de réseaux sociaux sur le Web comme nouveaux outils de marketing

subject: Mass Communications.

description: La montée en popularité des réseaux sociaux sur le Web ont bousculé les modèles traditionnels de marketing établis depuis plus d'un siècle au Québec et ailleurs dans le monde. La question de qui contrôle du message est au centre des préoccupations exprimées par de nombreux experts en marketing. Comment communiquer efficacement dans un univers où les individus sont désormais des acteurs impliqués dans l'échange d'information et d'opinions sur les biens et services offerts par les entreprises? Les internautes peuvent désormais influencer l'adoption de comportements consommatoires, de même que contribuer à faire fructifier ou à anéantir les efforts de commercialisation produits par les professionnels du marketing. Cette recherche a une double visée: d'une part, découvrir l'ampleur de l'adoption des réseaux sociaux comme outils de communication et, d'autre part, anticiper les tendances lourdes en communications de marketing sur le Web au Québec.

description: Objective. To evaluate the effect of metal artifact reduction techniques on dGEMRIC T₁ calculation with surgical hardware present. Materials and Methods. We examined the effect of stainless steel and titanium hardware on dGEMRIC T₁ maps. We tested two strategies to reduce metal artifact in dGEMRIC: 1) saturation recovery (SR) instead of inversion recovery (IR) and 2) applying the Metal Artifact Reduction Sequence (MARS), in a gadolinium-doped agarose gel phantom and in vivo with titanium hardware. T₁ maps were obtained using custom curve-fitting software and phantom ROIs were defined to compare conditions (metal, MARS, IR, SR). Results. A large area of artifact appeared in phantom IR images with metal when TI≤700ms. IR maps with metal had additional artifact both in vivo and in the phantom (shifted null points, increased mean T₁ (+151% IR ROIartifact) and decreased mean inversion efficiency (f; 0.45 ROIartifact, versus 2 for perfect inversion)) compared to the SR maps (ROIartifact: +13% T1 SR, 0.95 versus 1 for perfect excitation), however SR produced noisier T₁ maps than IR (phantom SNR: 118 SR, 212 IR). MARS subtly reduced the extent of artifact in the phantom (IR and SR). Conclusion. dGEMRIC measurement in the presence of surgical hardware at 3T is possible with appropriately applied strategies. Measurements may work best in the presence of titanium and are severely limited with stainless steel. For regions near hardware where IR produces large artifacts making dGEMRIC analysis impossible, SRMARS may allow dGEMRIC measurements. The position and size of the IR artifact is variable, and must be assessed for each implant/imaging set-up.
