description: Thermal diffusivity of silk fibroin films, α = (1.6 ± 0.24) × 10-7 m2 s-1, was measured by a direct contact method. It was shown to be reduced down to ∼1 × 10-7 m2 s-1 in the crystallized phase, consistent with the multi-domain composition of β-sheet assemblies. Crystalline silk with β-sheets was made by dipping into alcohol and was used as a positive electron beam lithography (EBL) resist. It is shown by direct IR imaging of the 1619 cm-1 amide-I CO spectral signature and 3290 cm-1 amide-A N-H stretching band that an e-beam is responsible for unzipping β-sheets, which subsequently results in exposed areas returning to a water soluble state. This makes it possible to develop a water-based biocompatible silk resist and use it in lithography applications. The general principles of protein crystallization, traceable to spectral changes in IR amide bands of silk, can be used as a guide for the creation of new protein EBL resists and to quantify the electron dose required for solubility. Foam formation and laser treatments of silk can provide new approaches in surface functionalization and fabrication of 3D bio-scaffolds.

description: While research has explored the individual barriers that negatively affect refugee care, there is a lack of research on how licensed clinical social workers (LCSWs) might affect refugee clients to whom they offer mental health care services. In particular, we know little about how LCSWs understand and deliver mental health care services to refugee clients. This is important because LCSWs are frontline workers in addressing refugee mental health care needs and may impact refugee mental health outcomes.
description: This paper helps fill this gap by examining the language of LCSWs when talking about and enacting refugee mental health care. I analyzed LCSW language to better understand how LCSWs make sense of refugee clients and refugee mental health care. Specifically, I analyzed LCSW language and how white supremacy culture (WSC) characteristics are enacted when discussing refugees and refugee mental health care.
description: Interview transcripts were analyzed using CDA to identify the dominant discourses that arose across LCSWs, using the existing language of white supremacy culture characteristics (Okun, 2021). Findings identified two discourses: discourse of power and discourse of care. By connecting discourse of power and discourse of care to an existing white supremacy culture framework, this dissertation identifies ways LCSWs sustain and transform existing power relations. Finally, this dissertation suggests action-based change across social work education, practice and research to move beyond established interventions that enact white supremacy culture.

description: Presented in this study is an investigation of turbulent flow and heat transfer near narrow gaps of rod bundles. At first, practical empirical correlations for the subchannel average and the gap local heat transfer coefficients were fitted to experimental results available in the literature. Then, the thesis presents a new technique, using a pendulum, for the calibration of hot-wire anemometers over low velocity ranges, a signal analysis procedure for three-sensor hot-wire probes, and a method for the enhancement of the results of the Variable Interval Time Average (VITA) conditional sampling technique, all used in the main experimental study. The experimental investigation was conducted in a rectangular channel with an aspect ratio of 2/3, containing a suspended rod, having a diameter equal to half the channel height. The rod was positioned so that it would form a narrow rod-wall gap with the channel base. The flow Reynolds number, based on bulk velocity and hydraulic diameter, was 140,000. Two-point correlations and conditional sampling measurements, using hot-wire anemometry, as well as flow visualization were employed in this study. The experimental investigation substantiated the occurrence of large-scale coherent structures in the gap region, documented their properties and proposed a physical model for them. An explanation for their formation and spatial configuration was also offered. The insensitivity of the intersubchannel mixing and the local heat transfer coefficient to the gap size was explained as a result of the presence of these coherent structures in the gap region. The turbulence structure in the gap region was also investigated. Measurements of the coherent, incoherent and Reynolds averaged statistical properties of the flow were presented and compared to those in turbulent pipe flow.

description: La presente etude vise a essentiellement a tester le modele theorique propose par Barrette et Berard (1998) relativement au concept integre de gestion de la performance. En effet, la recherche tente de determiner le lien entre les trois niveaux d'integration presentes dans ce modele, soit l'integration au niveau strategique, l'integration au niveau des composantes de la gestion des ressources humaines et l'integration au niveau des pratiques operationnelles de gestion de la performance, et la performance organisationnelle telle que mesuree a l'aide d'indicateurs percus. L'echantillon a l'etude est forme de 177 entreprises canadiennes de domaines d'activites varies. Les resultats indiquent que plus les pratiques de gestion de la performance integrent les elements de la gestion strategique de l'organisation, plus la mesure de la performance percue est grande. La premiere hypothese de recherche est donc corroboree. Les resultats demontrent egalement que plus le niveau de coherence entre les pratiques operationnelles liees au systeme de gestion de la performance est grand, plus la performance organisationnelle percue est elevee. La troisieme hypothese de recherche est donc corroboree. Toutefois, la deuxieme hypothese posee dans le cadre de la presente etude n'a pu etre que partiellement corroboree. Nous ne pouvons donc pas conclure, comme nous l'avions suggere en se basant sur la litterature consultee, que plus les pratiques de gestion de la performance sont complementaires avec les autres composantes de la gestion des ressources humaines, plus la mesure de la performance percue est grande.

description: Low back pain is a significant public health burden. It is both a leading cause of disability worldwide and one of the most expensive conditions to manage in the US. It is highly prevalent in the US military and a common cause of combat duty interruption. Clinical practice guidelines recommend non-invasive, non-drug therapies, typical of chiropractic care, for the treatment of low back pain. Previous work has demonstrated a benefit on low back pain intensity and pain- related disability when adding chiropractic care to usual medical care for US active-duty military members. The aim of this work is to explore how and for whom these effects occur.
description: We conducted secondary analyses of data from a pragmatic, multi-site trial comparing 6 weeks of treatment with usual medical care plus chiropractic care to usual medical care alone for US active-duty military members with low back pain. Natural effect, multiple mediator models were conducted to evaluate mediation of 12-week pain interference and pain intensity by 6-week biopsychosocial factors and vice versa. Linear mixed-effect regression models over baseline, 6, and 12 weeks were used to evaluate effect modifier x treatment x time interaction terms. When applicable, analyses were adjusted for factors such as baseline sex, age, site, low back pain duration, physical function, fatigue, sleep disturbance, anxiety, depression, satisfaction with participation in social role, pain interference, and pain intensity.
description: Moderate mediation of effect on pain occurred through mostly physical and social factors. Most of the effect on biopsychosocial factors occurred through pain intensity. Fatigue and anxiety were important effect modifiers of chiropractic care on pain at 12 weeks.
description: Chiropractic care improves outcomes for US active-duty military members mostly through effects on pain intensity leading to changes in other quality of life factors. Chiropractic care should be added to usual medical care for active-duty military members with higher levels of fatigue and anxiety to improve pain outcomes for these patients. Future work should determine if mechanisms and effect modifiers differ in non-military populations.

Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis proposes a detailed design layout for the next generation optical metropolitan network to be equipped with Reconfigurable Optical Add/Drop Multiplexer (ROADM) subsystems. It demonstrates the key features of ROADM subsystems including the development of ring-to-ring interconnection in optical domain. Simulation models are developed for the ROADM subsystems that can easily be configured according to the devices' available specification sheet. The developed simulation models have been verified with experimental measurements obtained from a reconfigurable all-optical metro network testbed. Such simulation modules will be valuable in planning and designing the next generation metro optical networks. Combining the outcome of the research results presented in the thesis, a hybrid reconfigurable add/drop module is proposed. The proposed hybrid architecture can achieve lower loss among the existing 3rd generation ROADM modules. The functionality of ROADMs can also be improved by an Intelligent ROADM subsystem proposed for the next generation dynamically provisioned wavelength network.

description: Objective To compare the association between different anthropometric measurements and incident type 2 diabetes mellitus (T2DM) and to assess their predictive ability in different regions of Germany. Methods Data of 10 258 participants from 4 prospective population-based cohorts were pooled to assess the association of body weight, body mass index (BMI), waist circumference (WC), waist-to-hip-ratio (WHR) and waist-to-height-ratio (WHtR) with incident T2DM by calculating HRs of the crude, adjusted and standardised markers, as well as providing receiver operator characteristic (ROC) curves. Differences between HRs and ROCs for the different anthropometric markers were calculated to compare their predictive ability. In addition, data of 3105 participants from the nationwide survey were analysed separately using the same methods to provide a nationally representative comparison. Results Strong associations were found for each anthropometric marker and incidence of T2DM. Among the standardised anthropometric measures, we found the strongest effect on incident T2DM for WC and WHtR in the pooled sample (HR for 1 SD difference in WC 1.97, 95% CI 1.75 to 2.22, HR for WHtR 1.93, 95% CI 1.71 to 2.17 in women) and in female DEGS participants (HR for WC 2.24, 95% CI 1.91 to 2.63, HR for WHtR 2.10, 95% CI 1.81 to 2.44), whereas the strongest association in men was found for WHR among DEGS participants (HR 2.29, 95% CI 1.89 to 2.78). ROC analysis showed WHtR to be the strongest predictor for incident T2DM. Differences in HR and ROCs between the different markers confirmed WC and WHtR to be the best predictors of incident T2DM. Findings were consistent across study regions and age groups (<65 vs ≥65 years). Conclusions We found stronger associations between anthropometric markers that reflect abdominal obesity (ie, WC and WHtR) and incident T2DM than for BMI and weight. The use of these measurements in risk prediction should be encouraged.

description: Polycomb repressive complex 2 (PRC2) is an essential epigenetic modifier mutated in several cancers and implicated in disease progression. PRC2 subunits, EED and SUZ12, are mutated in malignant peripheral nerve sheath tumors (MPNSTs), an aggressive, highly metastatic soft tissue sarcoma. In Chapter 1, I discuss the history of epigenetics and its roles in cancer development as it pertains to soft tissue sarcomas, specifically MPNSTs. I also discuss some challenges of treating sarcomas, completed and ongoing clinical trials utilizing epigenetic-based interventions, and promising preclinical epigenetic drug combinations. Finally, I consider future directions and how epigenetic crosstalk could be harnessed for MPNST treatment and monitoring.
description: In Chapter 2, I describe how loss of PRC2 increases MPNST metastatic-like phenotypes in vitro, in mouse models of metastasis, and patient tumor samples. This phenotype can be rescued with pharmacological and genetic inhibition of key pro-metastatic genes, MMPs and LOXs, which are upregulated in a PRC2-dependent manner.
description: In Chapter 3, I utilize publicly available datasets of gene expression and DNA methylation in sarcomas to interrogate PRC2-dependent mechanisms of epigenetic crosstalk. I have shown that loss of PRC2 correlates with a global hypermethylation profile, tumor microenvironment changes, and patient outcome. These findings have potential implications for biomarker development and patient outcomes in multiple sarcoma subtypes.
description: Our group was one of the first to utilize CRISPR technology to generate somatic patient-relevant mouse models of sarcoma. In Chapter 4, I highlight some discrepancies in the new indel analysis technology available to the field. I conducted a side-by-side analysis of three common platforms using Nf1 sanger sequencing files. These findings have implications for the preclinical and clinical space as the number of CRISPR-based clinical trials increase and progress from ex vivo applications to in vivo editing.
description: In Chapter 5, I discuss some of the differences between SUZ12 and EED mutations regarding PRC2-dependent signaling and metastatic-like phenotypes. I also consider the alternate functions of SUZ12 and EED in other epigenetic complexes that contribute to epigenetic crosstalk in MPNSTs. I end this chapter and dissertation by outlining how multi-omics approaches paired with validation in different model systems could be used to identify biomarkers for sarcoma diagnosis, monitoring treatment response, and increasing therapeutic benefit.
A new characterization of topologically amenable groups

description: A countable group G is called topologically amenable if there exist a compact Hausdorff space X on which G acts by homeomorphisms and weak*-continuous maps b n from X to the space, prob (G), of probability measures on G such that for every g ∈ G, limn→infinity supx∈X gbnx-bn gx1=0. For example, every amenable group is topologically amenable but not vice versa: The free group F2 is topologically amenable without being amenable. Inspired by a characterization of amenable groups due to Giordano and de la Harpe (a countable group G is amenable if and only if every continuous action of G on the Cantor set C admits an invariant probability measure), we give a new characterization of topologically amenable groups: A countable group G is topologically amenable if and only if it admits an amenable action on the Cantor set C.

description: Metals reach humans through food and drinking water intake and inhalation of airborne particles and can have detrimental health effects in particular for children. The metals presented here (lead, cadmium, chromium, and mercury) could lead to toxic effects such as neurotoxicity, mutagenicity, and have been classified as (possible) carcinogens. Using population representative data from the German Environmental Survey 2014-2017 (GerES V) from 3- to 17-year-old children on lead and cadmium in blood (n = 720) and on cadmium, chromium, and mercury in urine (n = 2250) we describe current internal exposure levels, and socio-demographic and substance-specific exposure determinants. Average internal exposure (geometric means) in blood was 9.47 (micro)g/L for lead and below 0.06 (micro)g/L (limit of quantification) for cadmium, and in urine 0.072 (micro)g/L for cadmium, 0.067 (micro)g/L for mercury, and 0.393 (micro)g/L for chromium, respectively. Younger children have higher concentrations of lead and chromium compared to 14-17-year-old adolescents, and boys have slightly higher mercury concentrations than girls. With respect to substance specific determinants, higher lead concentrations emerged in participants with domestic fuel and in non-smoking children with smokers in the household, higher levels of cadmium were associated with smoking and vegetarian diet and higher levels of mercury with the consumption of seafood and amalgam teeth fillings. No specific exposure determinants emerged for chromium. The health based guidance value HBM-I was not exceeded for mercury and for cadmium in urine it was exceeded by 0.6% of the study population. None of the exceedances was related to substantial tobacco smoke exposure. Comparisons to previous GerES cycles (GerES II, 1990-1992; GerES IV, 2003-2006) indicate continuously lower levels. © 2021 Elsevier GmbH

description: We measure the evolution of the quiescent fraction and quenching efficiency of satellites around star-forming and quiescent central galaxies with stellar mass at . We combine imaging from three deep near-infrared-selected surveys (ZFOURGE/CANDELS, Ultra Deep Survey, and UltraVISTA), which allows us to select a stellar-mass complete sample of satellites with . Satellites for both star-forming and quiescent central galaxies ('centrals') have higher quiescent fractions compared to field galaxies matched in stellar mass at all redshifts. We also observe 'galactic conformity': satellites around quiescent centrals are more likely to be quenched compared to the satellites around star-forming centrals. In our sample, this conformity signal is significant at for , whereas it is only weakly significant at and . Therefore, conformity (and thus satellite quenching) has been present for a significant fraction of the age of the universe. The satellite quenching efficiency increases with increasing stellar mass of the central, but does not appear to depend on the stellar mass of the satellite to the mass limit of our sample. When we compare the satellite quenching efficiency of star-forming centrals with stellar masses 0.2 dex higher than quiescent centrals (which should account for any difference in halo mass), the conformity signal decreases, but remains statistically significant at . This is evidence that satellite quenching is connected to the star formation properties of the central galaxy as well as to the mass of the halo. We discuss physical effects that may contribute to galactic conformity, and emphasize that they must allow for continued star formation in the central galaxy even as the satellites are quenched.

description: Bile acids (BAs) are increasingly recognised as metabolic regulators, potentially improving insulin sensitivity following bariatric surgery. However, physiological relevance of such observations remains unknown. Hence, we analysed serum BA composition and associated gut-derived hormone levels following lifestyle-induced weight loss in individuals with metabolic syndrome (MetS). 74 non-smoking men (45–55 yr) with MetS were randomised to a lifestyle-induced weight loss program (supervision via telemonitoring) or to a control arm. Before and after a 6 months intervention period clinical and laboratory parameters, body composition, serum BA profile, FGF-19, and GLP-1 concentrations were determined in fasting blood samples. 30 participants in the control and 33 participants in the treatment arm completed the study and were included in the data analysis. In participants of the treatment arm lifestyle-induced weight loss resulted in markedly improved insulin sensitivity. Serum levels of BA species and total GLP-1 decreased, while FGF-19 remained stable. Serum BA composition changed towards an increased 12α- hydroxylated/non-12α-hydroxylated ratio. None of these parameters changed in participants of the control arm. Our results demonstrate that improved metabolic control by lifestyle modifications lowers serum levels of BAs and GLP-1 and changes serum BA composition towards an increased 12α/non-12α ratio (ICTRP Trial Number: U1111-1158-3672).

description: The sea state of the Beaufort and Chukchi seas is controlled by the wind forcing and the amount of ice-free water available to generate surface waves. Clear trends in the annual duration of the open water season and in the extent of the seasonal sea ice minimum suggest that the sea state should be increasing, independent of changes in the wind forcing. Wave model hindcasts from four selected years spanning recent conditions are consistent with this expectation. In particular, larger waves are more common in years with less summer sea ice and/or a longer open water season, and peak wave periods are generally longer. The increase in wave energy may affect both the coastal zones and the remaining summer ice pack, as well as delay the autumn ice-edge advance. However, trends in the amount of wave energy impinging on the ice-edge are inconclusive, and the associated processes, especially in the autumn period of new ice formation, have yet to be well-described by in situ observations. There is an implicit trend and evidence for increasing wave energy along the coast of northern Alaska, and this coastal signal is corroborated by satellite altimeter estimates of wave energy.

description: The detection of five new fast radio bursts (FRBs) found in the 1.4-GHz High Time Resolution Universe high-latitude survey at Parkes, is presented. The rate implied is 7+5 -3 × 103 (95 per cent) FRBs sky-1 d-1 above a fluence of 0.13 Jy ms for an FRB of 0.128 ms duration to 1.5 Jy ms for 16 ms duration. One of these FRBs has a two-component profile, in which each component is similar to the known population of single component FRBs and the two components are separated by 2.4 ± 0.4 ms. All the FRB components appear to be unresolved following deconvolution with a scattering tail and accounting for intrachannel smearing. The two-component burst, FRB 121002, also has the highest dispersion measure (1629 pc cm-3) of any FRB to-date. Many of the proposed models to explain FRBs use a single high-energy event involving compact objects (such as neutron-star mergers) and therefore cannot easily explain a two-component FRB. Models that are based on extreme versions of flaring, pulsing, or orbital events, however, could produce multiple component profiles. The compatibility of these models and the FRB rate implied by these detections is discussed.

description: Glyphosate-based pesticides are the highest-volume used herbicides worldwide. International concerns regarding the potential human adverse effects of glyphosate exposures have heightened since IARC classified glyphosate as probably carcinogenic to humans. Human biomonitoring (HBM) studies have identified ubiquitous exposure to glyphosate and its main breakdown product, aminomethylphosphonic acid (AMPA), from environmental exposures. The IMAGE research project aimed to investigate farm and non-farm families' exposure to glyphosate while aligning with the Human Biomonitoring for Europe (HBM4EU) initiative. The study recruited non-farm and farm families (who use glyphosate on their farms). Each family member provided a urine sample that was analysed using gas chromatography coupled with tandem mass spectrometry, with a limit of quantification of 0.05 (micro)g/L for glyphosate and AMPA. In addition to general information on background exposures in farm and non-farm families, we investigated relationships in exposure between families and family members. We recruited 68 families, including 54 non-farm and 14 farm families (180 vs. 45 individuals). Some pesticide users (n = 14, all male farmers) had slightly elevated AMPA levels compared to other adult participants but, overall, we observed no significant differences between farm and non-farm families. The main metabolite, AMPA, was quantifiable in twice as many samples as glyphosate (61% vs. 32%), with a maximum concentration of 7.24 (micro)g/L vs. 3.21 (micro)g/L. Compared to previous studies, exposure levels were relatively low and far below current health-based guidance values (3% or less for glyphosate and AMPA). Study results suggest potential exposures from residential co-exposures or living with a pesticide user. This is the first study internationally to investigate glyphosate and AMPA across family members (farm and non-farm). We found comparably low glyphosate and AMPA exposures among these families. These results enhance our understanding of glyphosate exposures for different demographic groups and contribute to the scientific knowledge on exposures required for regulatory risk assessments and the re-evaluation of glyphosate in 2022 by the European Commission. © 2022 by the authors

description: We perform a kinematic analysis of galaxies at z ∼ 2 in the COSMOS legacy field using near-infrared (NIR) spectroscopy from Keck/MOSFIRE as part of the ZFIRE survey. Our sample consists of 75 Ks-band selected star-forming galaxies from the ZFOURGE survey with stellar masses ranging from log(M ∗/M ₒ) = 9.0-11.0, 28 of which are members of a known overdensity at z = 2.095. We measure H emission-line integrated velocity dispersions (σ int) from 50 to 230 km s⁻¹, consistent with other emission-line studies of z ∼ 2 field galaxies. From these data we estimate virial, stellar, and gas masses and derive correlations between these properties for cluster and field galaxies at z ∼ 2. We find evidence that baryons dominate within the central effective radius. However, we find no statistically significant differences between the cluster and the field, and conclude that the kinematics of star-forming galaxies at z ∼ 2 are not significantly different between the cluster and field environments.

description: The aim of the thesis was to study the molecular genetic and function offing, a novel gene having important role in central nervous system (CNS) and respiratory (tracheal) system development during Drosophila embryogenesis. We established by sequencing the gene that jing has three C2H2 zinc finger motifs, and several putative transcriptional regulatory sequences. jing plays an essential role in controlling CNS midline and tracheal cell differentiation. Mutation results in the appearance of a premature stop codon in the middle of the second zinc finger decreases survival ratio in those cells. This effect appears to be a result of the functional relationship between jing and the Egfr (Epidermal growth factor receptor) pathway in the developing CNS midline and trachea. jing is also a target of Trachealess:: Tango (Trh::Tgo) heterodimers, two members of the bHLH-PAS transcription factors, which play essential role in the development of CNS and trachea. However, jing expression is under multiple control mechanisms including auto-inhibition, inhibition by the POU domain transcription factor Drifter and the ETS transcription factor Aop. On the other hand, jing is required for the balance between repression and activation that regulates Trh- and Tgo-mediated btl transcription and subsequent growth factor levels to control signaling during the primary and secondary branching processes in the respiratory system. In conclusion, jing is a downstream target of Trh::Tgo complex and its function is required for CNS midline and tracheal cell development during Drosophila embryogenesis.
Canada and the Far East crisis in 1941: Intelligence, strategy and the coming of the Pacific War
Creators: name: Wilford, Timothy

Subjects: subject: History, Canadian.
subject: History, Modern.

description: Historians specializing in the Second World War have often characterized Canada as an Atlantic Power whilst tending to ignore its important role in the Pacific. Moreover, historians have often characterized Canada as a very minor component of the Anglo-American alliance that emerged in 1941. Canada's response to the Far East crisis may be better understood through a detailed study of the intelligence operations and strategic planning that preceded the outbreak of war in the Pacific. Several primary sources, including contemporaneous war records, internal histories, memoirs and post-war accounts from former participants in wartime intelligence operations, suggest that Canada was better prepared for the Pacific War than previously known. In 1941, Canadian intelligence staff and strategists worked closely with their Allied and American counterparts to prepare for war with Japan. Canada monitored Japan's preparations for war and participated in Allied-American conferences concerning the Far East crisis, using multiple intelligence sources to optimize strategic planning. Throughout the developing crisis in the Far East, Canada sought to avoid conflict with Japan until American participation was assured, but fully anticipated action in Southeast Asia and the North Pacific, making various preparations for national and imperial defence.

Locating mobile agents through distributed mechanisms
Creators: name: Xie, Ming
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2008
Subjects: subject: Computer Science.

description: Mobile agents are processes that may be dispatched from a source computer and be transported to remote servers for execution. In any mobile agent system, the ability to communicate with agents in real-time is essential for retrieving any data or information that they have collected, and for supporting coordination and cooperation among them. Communication with a mobile agent requires the ability to track it. In the thesis, we propose several distributed mechanisms for tracking (or locating) mobile agents. We first propose a method based on distributed hashing table (DHT) to locate mobile agents efficiently in a large-scale network. The idea is to treat mobile agents and hosts similarly to the way peers are treated in a peer-to-peer system, and to implement a lookup protocol that is based on that principle, while taking care of the mobile nature of the agents. We then introduce a new locating mechanism. Our technique is based on appropriate delays that the mobile agents must perform while moving on the network so to facilitate its tracking, should it be needed. The searching agent computes a particular searching path that will guarantee the tracking within one traversal of the network. We indicate various strategies, and we perform experiments for computing the searching path and for comparing their performances in synchronous and asynchronous settings, in arbitrary and specific topologies.
Organizational effectiveness: The case of Oman Football Association.
Creators: name: Al-Tauqi, Mansour Sultan.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Business Administration, Management.

description: The purpose of the study was to determine the effectiveness of the Oman Football Association (OFA) in selected dimensions, namely, complexity, formalization, centralization, activities to ensure resources, work flow activities, and control activities, identification activities, and homeostatic activities. The study used a document analysis to gather qualitative data, and a survey to collect constituent perceptions on these dimensions. Four constituent groups were identified: administrators, official referees, national team athletes, and coaches. Their perceptions were assessed by a nine point scale ranging from $-$4 to +4. Fifty-eight participants responded to a survey questionnaire. A Kruskal Wallis non parametric test was carried out to test differences between constituent's perceptions in the five dimensions. From the overall perceptions all dimensions were perceived to be contributing to organizational effectiveness. The only significant difference was found between administrators, and referees and coaches in the control dimension. This finding supported the statement problem examined in the current study, and indicated that there is need for a valid evaluation process for programs and personnel within the organization. The constituent's comments to the open-ended questions revealed some important issues, the employee involvement in decision making, the recruitment of professional administrators, and the influence of the General Organization of Sport and Youth activities (GOSYA) in OFA's activities.
"Évaluation de la réponse du modèle CANBEIS (CANadian Biogenic Emissions Inventory System) aux modifications de certains facteurs environnementaux."
Creators: name: Ratté, Dominique.
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Physics, Atmospheric Science.

description: The evaluation of the model CANBEIS that allows the estimation of biogenic VOC emissions has been performed through various sensitivity analyses. Numerous simulations involving the variation of key parameters such as meteorological conditions were conducted and analyzed in comparison with the results from existing literature. Most of the time, there were similarities in the comparisons although in some cases, divergence brought up the consideration of re-assessment of some methodologies in the model. The impact of the terrain elevation on temperature and consequently on emissions, was also evaluated to determine its potential role in the model. This analysis, performed for the lower Fraser Valley in British Columbia, has confirmed that when terrain elevation was involved in the calculation of emissions, the latter indicated significant variations.

Subjects: subject: Education, Technology.

description: The academic environment has been witnessing the rise of a new form of teaching and transferring knowledge; that is telelearning via the Internet. A certain number of problem areas are still facing telelearning practitioners, which should be worked an and resolved soon, if most of the expectations of a universal effective and successful telelearning environment are to be realized. Some of these issues include Internet security, copyrights of digital material, and accreditation of on-line degrees and programs. This thesis includes four parts. Part I includes a description of a variety of synchronous and asynchronous Internet tools, as well as their advantages and drawbacks. In part II, some case studies of Internet-based telelearning applications are described, in addition to a discussion of the results of two investigations about the current implementations of the Internet tools within a telelearning setting. Part III provides an analysis of the different economics of telelearning which comprises costs related to both: the students and the institution. Finally, in part IV a number of Internet issues relating to telelearning were examined. These include: security and policy issues such as copyright of on-line material, accreditation of on-line degrees and virtual institutions, on-line academic fraud, and evaluation of the Web's material.

description: In this thesis, the theoretical models describing the physical origins of differential group delay (DGD) are presented, and methods of measuring the DGD process are discussed. Three measurement methods are evaluated for their practical usefulness (Jones matrix eigen-analysis, wave-length-scanning and interferometric techniques). Characterization based on measurements of the mean and correlation coefficients of the DGD process with respect to time, wave-length/frequency and temperature are made using the Jones matrix eigen-analysis method. A comparison between the measurements and numerical simulations based on the physical models of the origins of PMD are made. Measurements of the DGD of a system's components and the overall system are made to validate the theoretical models we have that describe how component DGD relates to the overall system DGD. The results of the measurement agree with the theoretical models that the DGD is described by a Maxwellian distribution, and support the cascaded link rule for predicting the system DGD; the correlation bandwidth measurement is seen to agree with the findings of the numerical simulations.
