description: Signal decomposition finds its applications in a wide range of areas. The problem of basis selection for signal decomposition consists of determining a small, possibly smallest, subset of vectors chosen from a large redundant set of vectors to match the given data. However, it is shown that finding the sparsest solution to linear systems is a nondeterministic polynomial time (NP) hard problem and requires combinatorial search. For a simpler solution, greedy heuristic algorithms, namely matching pursuit (MP) algorithms are proposed. These algorithms require sequential selection of basis vectors from a set of vectors, termed as dictionary. This dictionary can be undercomplete, overcomplete or complete, depending on the number of basis vectors it contains. The contributions of this dissertation are composed of two complementary parts. In the first part, the limitations of the MP based algorithms are considered. Combination of orthogonal matching pursuit (OMP) algorithm with tree-based combinatorial search techniques is proposed in order to overcome the limitations of the greedy heuristic algorithms. A novel flexible tree-search based OMP (FTB-OMP) algorithm is introduced for sparse signal representations. The algorithm provides some design parameters, giving flexibility to establish a tradeoff between performance and complexity. The efficiency is achieved by using a correlation based pruning in the search tree, and reducing the number of leaves as the depth of nodes increases. It must be noted that this algorithm can be applied to any kind of detection problem that can be modeled as a set of linear equations. In the second part of the dissertation, parameter estimation problems related to wireless communications are considered. These problems are channel estimation, direction of arrival (DOA) estimation and multi-user detection (MUD). These problems are modeled with different types of dictionaries due to their physical characteristics. The channel estimation problem is modeled with undercomplete dictionary. DOA estimation and MUD have overcomplete and complete dictionary models, respectively. It is shown that the family of MP algorithms, especially FTB-OMP, provides a low complexity solution for parameter detection problems with different types of dictionaries. These algorithms provide a practical solution for detection and estimation problems that are widely encountered in wireless communications.

description: Background: Depression has been associated with impaired nitric oxide (NO)-mediated vasodilation and vascular dysregulation (VD). Whether depression and NO levels will disturb retinal hemodynamics is not clear. Objectives and methods: Associations between the retinal vasculature, diastolic ocular perfusion pressure (DOPP) as measure of hypoperfusion, NO metabolites (NOx) and depression symptoms were assessed. Chronic VD risk markers [depression symptoms (Patient Health Questionnaire/PHQ-9 ≥ 10) and 24h pulse pressure] were determined in a bi-ethnic cohort (n=313; 48.6 ± 9 years; 53.9% men). At 3 year follow-up, retinal vessel calibre and retinopathy signs were quantified from digital images. Salivary NOx was obtained pre- and post-flicker light-induced provocation (FLIP). DOPP was defined as diastolic blood pressure minus intraocular pressure. Results: Chronic VD risk was evident in Blacks opposed to acute risk in Whites (P<0.05). At follow-up, retinopathy (Blacks 60.4%/Whites 39.6%), lower pre-FLIP (μM) and higher post-FLIP NOx (changes from baseline, %), arteriolar narrowing and wider venular calibre values were evident in Blacks compared to Whites, independent of confounders. A wider venular calibre, an index of stroke risk, was associated with chronic depression symptoms [cut point 248 MU: Area under the curve 0·61 (95% CI: 0·51, 0·72); 71% sensitivity; 55% specificity] as well as with hypoperfusion in the Blacks. In this group, arteriolar narrowing was associated with hypoperfusion; and attenuated arteriolar dilation with increased post-FLIP NOx responses. Conclusions: Chronic depression symptoms may alter NO regulation and facilitate VD. NO-mediated vasoconstriction presumably impeded perfusion, retinal hemodynamics and -remodelling; potentiating stroke risk in Blacks.
An exploratory study of the psychological and behavioural impacts of genetic testing for thrombophilia among asymptomatic first-degree relatives of patients with venous thrombosis

description: Objective. To conduct a preliminary exploration of psychological outcomes and health behaviour in individuals undergoing testing for genetic mutations associated with thrombophilia. Methods. Subjects were 57 carriers and 54 non-carriers identified through an existing pilot study. Part I analyzed perceived risk and psychological data collected at baseline, 1 week and 12 months post-test. Part II used a cross-sectional survey to collect data regarding: test implications, perceived causes and control, and behaviour change post-test. Results. Accuracy of risk perception improved post-test due to decreased risk perception among non-carriers. No major psychological harms were identified, but a subgroup of carriers may experience distress. Participants had a high sense of control over their risk of venous thromboembolism and had a good understanding of risk factors. Many tried to change their behaviours post-test, but did not report doing this specifically to reduce their risk of a blood clot. Conclusions. This exploratory study suggests no major psychological harm arising from genetic testing, but its findings need replication with larger samples.

description: The hyperinsulinemia of obesity is a function of both increased pancreatic insulin secretion and decreased insulin clearance, and contributes to cardiovascular risk. Whilst weight loss is known to enhance insulin clearance, there is a paucity of data concerning the underlying mechanisms. This study was conducted to examine the inter-relationships between changes in sympathetic nervous system (SNS) activity, vascular function and insulin clearance during a weight loss program. Seventeen non-smoking, un-medicated individuals aged 55 ± 1 years (mean ± SEM), body mass index (BMI) 33.9 ± 1.7 kg/m(2), underwent a 4-month hypocaloric diet (HCD), using a modified Dietary Approaches to Stop Hypertension diet, whilst seventeen age- and BMI-matched subjects acted as controls. Insulin sensitivity and insulin clearance were assessed via euglycemic hyperinsulinemic clamp (exogenous insulin clearance); hepatic insulin extraction was calculated as fasting C-peptide to insulin ratio (endogenous insulin clearance); SNS activity was quantified by microneurographic nerve recordings of muscle sympathetic nerve activity (MSNA) and whole-body norepinephrine kinetics; and vascular function by calf venous occlusion plethysmography and finger arterial tonometry. Weight loss averaged -8.3 ± 0.6 % of body weight in the HCD group and was accompanied by increased clamp-derived glucose utilization (by 20 ± 9 %, P = 0.04) and exogenous insulin clearance (by 12 ± 5 %, P = 0.02). Hepatic insulin extraction increased from 6.3 ± 0.8 to 7.1 ± 0.9 (P = 0.09). Arterial norepinephrine concentration decreased by -12 ± 5 %, whole-body norepinephrine spillover rate by -14 ± 8 %, and MSNA by -9 ± 5 bursts per 100 heartbeats in the HCD group (P all >0.05 versus control group). Step-wise regression analysis revealed a bidirectional relationship between enhanced exogenous insulin clearance post weight loss and reduction in calf vascular resistance (r = -0.63, P = 0.01) which explained 40 % of the variance. Increase in hepatic insulin extraction was predicted by enhanced finger reactive hyperaemic response (P = 0.006) and improvement in oral glucose tolerance (P = 0.002) which together explained 64 % of the variance. Insulin clearance is independently and reciprocally associated with changes in vascular function during weight loss intervention. Trial registration ClinicalTrials.gov: NCT01771042 and NCT00408850.

Behavior of low-carbon cementitious composites incorporating wood ash and basalt powder for enhanced strength and durability
Creators: name: Razi, Mohd Akif
Publisher: name: University of British Columbia
Year: 2025

description: This research explores the potential of wood ash and basalt powder in developing sustainable, low-carbon cementitious composites. The study evaluates the effectiveness of wood ash as a supplementary cementitious material and basalt powder as a sand substitute in mortar and concrete mixtures. Wood ash was incorporated as a cement replacement, up to 30%, and basalt powder was used to replace the sand by up to 100%. A series of experimental tests were carried out to assess fresh properties, mechanical performance, microstructural characteristics, and durability, including freeze-thaw resistance, chloride penetration, sorptivity, and elevated temperature exposure. Results indicate that increasing wood ash content was detrimental, whereas increasing basalt powder was reported to positively impact the mortar and concrete properties. At optimal replacement levels, wood ash enhances long-term strength due to its pozzolanic activity, while basalt powder improves particle packing, leading to denser concrete. The optimal replacement ratio of wood ash was recorded as 10% in both mortar and concrete mixes. In the case of basalt powder, the optimal replacement was concluded as 100% and 50% in mortars and concrete, respectively. The strength was found to be increased by 60.81% compared to the reference sample after 28 days at 100% substitution of basalt powder as fine aggregate. The strength of mortar and concrete mixes was improved by 25% and 18.2% at 10% wood ash content in addition to basalt powder as sand substitute after 28 days. However, the addition of these materials resulted in reduced workability, requiring appropriate admixtures for practical applications. Besides, incorporating wood ash and basalt powder in concrete production can reduce environmental impact by utilizing industrial waste, lowering carbon emissions, and minimizing the depletion of natural resources. These findings provide valuable insights for researchers and industry professionals seeking sustainable alternatives in modern construction.

description: In November 2018, an EU workshop on non-chemical alternatives for rodent control was held in Brussels. The overall goal was to take the next step into the direction of rodent control with less risks for the environment and human health. During the workshop, it became evident that rodent traps are already viable alternatives to rodenticides in professional rodent control. However, the lack of criteria for their assessment is hindering the establishment of traps as a first choice control measure and their recognition as non-chemical alternatives within the comparative assessment for (anticoagulant) rodenticides under the EU Biocides Legislation. It was thus decided to initiate a working party. Its tasks should be to define criteria for the assessment and certification of traps and to draft a testing guideline. A broader range of experts is expected to discuss a draft testing guidelines in a follow-up workshop in 2020. Quelle: Bericht

description: Background: The exact pathophysiology of Tako-Tsubo cardiomyopathy (TTC) remains unknown but a role for sympathetic hyperactivity has been suggested. Up to now, no direct evidence of sympathetic nerve hyperactivity has been established nor involvement of sympathetic baroreflex identified. The aim of our study was to determine, by direct sympathetic nerve activity (SNS) recording if sympathetic nervous system activity is increased and spontaneous baroreflex control of sympathetic activity reduced in patients with TTC. Methods: We included 13 patients who presented with TTC and compared their SNS activity and spontaneous baroreflex control of sympathetic activity with that of 13 control patients with acutely decompensated chronic heart failure. SNS activity was evaluated by microneurography, a technique assessing muscle sympathetic nerve activity (MSNA). Spontaneous baroreflex control of sympathetic activity was evaluated as the absolute value of the slope of the regression line representing the relationship between spontaneous diastolic blood pressure values and concomitant SNS activity. Control patients were matched for age, sex, left ventricular ejection fraction and creatinine clearance. Results: The mean age of the patients with TTC was 80 years, all patients were women. There were no significant differences between the two groups of patients for blood pressure, heart rate or oxygen saturation level. TTC patients presented a significant increase in sympathetic nerve activity (MSNA median 63.3 bursts/min [interquartile range 61.3 to 66.0] vs median 55.7 bursts/min [interquartile range 51.0 to 61.7]; p = 0.0089) and a decrease in spontaneous baroreflex control of sympathetic activity compared to matched control patients (spontaneous baroreflex control of sympathetic activity median 0.7%burst/mmHg [interquartile range 0.4 to 1.9] vs median 2.4%burst/mmHg [interquartile range 1.8 to 2.9]; p = 0.005). Conclusions: We report for the first time, through direct measurement of sympathetic nerve activity, that patients with TTC exhibit elevated SNS activity associated with a decrease in spontaneous baroreflex control of sympathetic activity. These data may explain the pathophysiology and clinical presentation of patient with TTC.
L'intégration de la variation sociolinguistique en français langue seconde: Une étude de documents pédagogiques

description: La présente thèse s'inscrit dans un courant interdisciplinaire de recherche en langue seconde qui utilise les techniques et connaissances de la sociolinguistique variationniste, afin de tirer des conclusions quant à l'inclusion de la variation sociolinguistique dans les documents pédagogiques (DP) de français langue seconde (FLS). Des études telles que Mougeon, Nadasdi et Rehner (2002) montrent que les apprenants éprouvent des difficultés à acquérir la compétence sociolinguistique qui leur permet d'adapter leur langue au contexte socioculturel. Cette thèse s'interroge sur le rôle potentiel des DP et cherche à répondre à la question suivante: "dans quelle mesure les DP de FLS utilisés en contexte communicatif incluent-ils la variation sociolinguistique?". Une analyse systématique de quatre variables (le futur, la négation, les auxiliaires et les phrases hypothétiques) dans un corpus de 38 DP utilisés dans les classes de FLS de la 9eme à la 12eme dans la région d'Ottawa, permet de conclure que la variation sociolinguistique est généralement ignorée ou mal représentée. En effet, les variantes vernaculaires sont incluses en quantité insuffisante et les variantes standard, en quantité excessive. De plus, très peu de commentaires ou explications soulignent la variation sociolinguistique et lorsque de tels mentions explicites sont présentés, elles vont à l'encontre de ce que l'on observe dans la langue des locuteurs natifs. Les résultats montrent donc que les DP sont en effet une cause possible sinon probable des difficultés encourues par les apprenants de FLS.

description: Neuroadrenergic function in type 2 diabetic (T2D) patients without neuropathy is poorly characterized. We therefore compared sympathetic nervous system activity at rest and during an oral glucose tolerance test in obese metabolic syndrome (MetS) subjects classified as glucose intolerant (impaired glucose tolerance [IGT]; n = 17) or treatment-naive T2D (n = 17). Untreated subjects, matched for age (mean 59 ± 1 year), sex, BMI (32.4 ± 0.6 kg/m(2)), and family history of diabetes were studied. We measured resting muscle sympathetic nerve activity (MSNA) by microneurography, whole-body norepinephrine kinetics by isotope dilution, insulin sensitivity by euglycemic-hyperinsulinemic clamp (steady-state glucose utilization adjusted for fat-free mass and steady-state insulin concentration [M/I]), and MetS components. T2D subjects had higher resting MSNA burst incidence (67 ± 4 versus 55 ± 3 bursts per 100 heartbeats; P = 0.05) and arterial norepinephrine levels (264 ± 33 versus 167 ± 16 pg/mL; P = 0.02), lower plasma norepinephrine clearance (by 17%; P = 0.03), and reduced neuronal reuptake compared with IGT subjects (by 46%; P = 0.04). Moreover, norepinephrine spillover responses to glucose ingestion were blunted in T2D subjects. The M/I value independently predicted whole-body norepinephrine spillover (r = -0.47; P = 0.008), whereas fasting insulin level related to neuronal norepinephrine reuptake (r = -0.35, P = 0.047). These findings demonstrate that progression to T2D is associated with increased central sympathetic drive, blunted sympathetic responsiveness, and altered norepinephrine disposition.
Moral Identity-Driven Communication Model for the Not-For-Profit Sector: A Social Media Context

Publisher: name: Swinburne
Year: 2024

description: This thesis proposes a novel communication framework that aims to help not-for-profit organisations strategically shape their social media messages in order to generate consumer support for social causes. Grounded in moral identity theory, the framework suggests that marketers have the power to trigger consumers’ moral identity by strategically framing social media messages. This approach has the potential to motivate consumers to embrace and actively endorse social causes on social media. The research further identifies the specific conditions within social media environments that maximise the impact of moral identity-driven messages on consumer online endorsements.

description: Congestion control is an important issue and challenge in both wired and wireless networks. This thesis evaluates the feasibility of implementing an adaptive Proportional and Integral (PI) rate control algorithm for streaming traffic applications in wireless Ad-hoc networks. A performance analysis and a comparison of this adaptive rate controller with TCP New Reno have been conducted. The performance of this congestion controller in different stationary and mobile scenarios is evaluated by means of simulation. The simulation measurements take into consideration the impact of the number of nodes, the number of simultaneous traffic flows, node mobility, as well as the interaction of different routing protocols. The simulation results demonstrate that the adaptive PI rate control algorithm can improve the overall average throughput.

description: Drawing freehand sketches of mechanical components on multimedia devices for AI-based engineering modeling has become a new trend. However, its development is being impeded because existing works cannot produce suitable sketches for data-driven research. These works either generate sketches lacking a freehand style or utilize generative models not originally designed for this task resulting in poor effectiveness. To address this issue, we design a two-stage generative framework mimicking the human sketching behavior pattern, called MSFormer, which is the first time to produce humanoid freehand sketches tailored for mechanical components. The first stage employs Open CASCADE technology to obtain multi-view contour sketches from mechanical components, filtering perturbing signals for the ensuing generation process. Meanwhile, we design a view selector to simulate viewpoint selection tasks during human sketching for picking out information-rich sketches. The second stage translates contour sketches into freehand sketches by a transformer-based generator. To retain essential modeling features as much as possible and rationalize stroke distribution, we introduce a novel edge-constraint stroke initialization. Furthermore, we utilize a CLIP vision encoder and a new loss function incorporating the Hausdorff distance to enhance the generalizability and robustness of the model. Extensive experiments demonstrate that our approach achieves state-of-the-art performance for generating freehand sketches in the mechanical domain. Project page: https://mcfreeskegen.github.io .

Troublingly, the bacteria within a biofilm are adaptively resistant to antibiotic treatment and it can take up to 1000 times more antibiotic to kill cells within a biofilm when compared to planktonic bacterial cells. Identifying and optimizing compounds that specifically target bacteria growing in biofilms is required to address this growing concern and the reported antibiofilm activity of natural and synthetic host defence peptides has garnered significant interest. However, a standardized assay to assess the activity of antibiofilm agents has not been established. In the present work, we describe two simple assays that can assess the inhibitory and eradication capacities of peptides towards biofilms that are formed by both Gram-positive and negative bacteria. These assays are suitable for high-throughput workflows in 96-well microplates and they use crystal violet staining to quantify adhered biofilm biomass as well as tetrazolium chloride dye to evaluate the metabolic activity of the biofilms. The effect of media composition on the readouts of these biofilm detection methods was assessed against two strains of Pseudomonas aeruginosa (PAO1 and PA14), as well as a methicillin resistant strain of Staphylococcus aureus. Our results demonstrate that media composition dramatically alters the staining patterns that were obtained with these dye-based methods, highlighting the importance of establishing appropriate biofilm growth conditions for each bacterial species to be evaluated. Confocal microscopy imaging of P. aeruginosa biofilms grown in flow cells revealed that this is likely due to altered biofilm architecture under specific growth conditions. The antibiofilm activity of several antibiotics and synthetic peptides were then evaluated under both inhibition and eradication conditions to illustrate the type of data that can be obtained using this experimental setup.

description: We report on quartz and glass cutting by a lateral scanning of femtosecond pulses (150 fs at 1 kHz repetition rate) of 800 nm wavelength at room and low pressure (5 Torr) air ambience. Pulses were focused by a low numerical aperture (NA < 0.1) objective lens. Optimization of fabrication conditions: pulse energy and scanning speed were carried out to achieve large-scale (millimeter-to-centimeter) cutting free of microcracks of submicron dimensions along the edges and walls of the cut. Cutting through out the samples of 0.1-0.5 mm thickness was successfully achieved without apparent heat affected zone. At low air pressure (5 Torr) ambience, redeposition of ablated material was considerably reduced. It is demonstrated that the damage on the rear surface was induced by the stress waves, which originated from the plasma ablation pressure pulse. The mechanism of femtosecond-laser cutting of transparent materials at high irradiance and the influence of stress waves generated by plasma plume are discussed.

Revisiting the partition of Bengal in 1947 : an epistolary search for the human dimension
Creators: name: Sengupta, Sheila
Publisher: name: University of British Columbia
Year: 2025

description: Although much has been written about the ‘high politics’ of Partition and the conflict between the Congress Party and the Muslim League in India, little attention has been paid to the active presence of other political organizations, namely the Hindu Mahasabha and the everyday logistics of how Bengali people, mostly Hindus, experienced this event. This study attempts to address that lacuna by analyzing letters written in the immediate months before, during and after the Partition (1946-1952). It revisits the Partition of Bengal, using an epistolary approach that analyzes the voices of a diversity of dispossessed people within translated archival letters. Given the paucity of other forms of contemporary testimony in official records, insights gained from these letters—both personal and public—help build a partial archive to help understand how the twin events of Independence and Partition played out in people’s lives. I argue that, as fragmented life documents, the letters provide immense insight into the multiple dimensions of communal Partition violence. When contextualized historically through these letters, the story of Partition gets transformed from one about two nations, two communities, and two religions into a story about immediate responses and needs in the face of dispossession, dislocation, and disillusionment. By focusing on a submerged archive of voices not counted in official histories, I explore Partition both as geopolitical event and also, an emotional process. This study’s significance lies in addressing a need to bring Bengal more centrally within the purview of Partition Studies. I argue that what we understand as the Partition experience may extend significantly when Partition Studies include a more detailed Bengal story as well.
From moral panic to moral narrative: The construction of 'The Prostitute' in "The Province" newspaper, 1993--2003

description: Based on previous literature, the dominant discourse of 'The Prostitute' was established, deeming it a high-risk trade, among other personal characteristics commonly associated with sex workers. A qualitative content analysis was conducted on a widely distributed provincial newspaper, The Province, in order to assess any meaningful discursive shifts in the discourse of 'The Prostitute' between 1993 and 2003. Notions of risk and discourse were incorporated into prior literature on moral panic theory. With the use of this theory, it was found that this rise in media attention could not be said to be a moral panic, but instead, a moral narrative. The latter term was used to signify the moral dimension of a discourse in which the message is directed toward the victim and pertains largely to a discourse of risk and proper risk management, otherwise implicating the subject their victimization. It was found that The Province reinforced the dominant discourse of 'The Prostitute' by dissociating the Missing Women from murdered sex workers from other locations. Setting them apart to be acknowledged, emphasized the quasi-victim status given those involved in the sex industry. The murders were incorporated into a moral narrative that served as a warning to sex workers, thus problematizing them as victims. Presented as either illegitimate choice makers or victims of social ills and prostitution itself, the problems identified throughout the coverage of this case pertained mostly to a serial killer, while the solutions offered spoke largely to a need to get women off drugs and out of prostitution. This again reaffirmed the high-risk discourse of prostitution, rather than recognizing them as 'true' victims, and considering realistic and meaningful options that might reduce the particular vulnerability of street sex workers.

description: Background: Over the past several decades, there have been numerous peer-reviewed articles written about people who use drugs (PWUDs) from the Downtown Eastside neighborhood of Vancouver, Canada. While individual researchers have engaged and acknowledged this population as participants and community partners in their work, there has been comparatively little attention given to the role of PWUDs and drug user organizations in directing, influencing, and shaping research agendas. Methods: In this community-driven research, we examine 20 years of peer-reviewed studies, university theses, books, and reports that have been directed, influenced, and shaped by members of the activist organization the Vancouver Area Network of Drug Users (VANDU). In this paper, we have summarized VANDU’s work based on different themes from each article. Results: After applying the inclusion criteria to over 400 articles, 59 items containing peer-reviewed studies, books, and reports were included and three themes of topics researched or discussed were identified. Theme 1: ‘health needs’ of marginalized groups was found in 39% of articles, Theme 2: ‘evaluation of projects’ related to harm reduction in 19%, and Theme 3: ‘activism’ related work in 42%. Ninety-four percent of co-authors were from British Columbia and 44% of research was qualitative. Works that have been co-authored by VANDU’s members or acknowledged their participations created 628 citations. Moreover, their work has been accessed more than 149,600 times. Conclusions: Peer-based, democratic harm reduction organizations are important partners in facilitating groundbreaking health and social research, and through research can advocate for the improved health and wellbeing of PWUDs and other marginalized groups in their community. This article also recommends that PWUDs should be more respectfully engaged and given appropriate credit for their contributions.

A comparative study of individual travel patterns of urban fringe dwellers in Ottawa, Canada; Kuala Lumpur, Malaysia; and Yogyakarta, Indonesia

description: A technique for gathering, analyzing and grouping individual travel pattern data is developed and tested in an international case study to compare the travel behaviours of urban fringe dwellers in three cities. The cities are Ottawa, Canada; Kuala Lumpur, Malaysia; and Yogyakarta, Indonesia. The technique makes a contribution to research methodology through implementation of the following elements in combination: (1) an urban fringe, spatial, residential sampling procedure; (2) a household survey that gathers detailed data on respondents and their travel patterns for three days over the period of a week including both work and non-work time periods; and, (3) an analysis that decomposes the travel patterns into various dimensions, facilitated by a Geographic Information System (GIS) which is followed by a segmentation of the travel patterns using cluster analysis. Based on the Ottawa component of the survey, an approach is suggested for collecting spatial familiarity data from urban fringe dwellers. The approach explores relationships involving respondents' previous residential locations in the city region. This evaluates their areal familiarity: a factor which influences their travel patterns. The comparative study examines empirical relationships by means of comprehensive data analysis and hypothesis testing. The dimensions of travel investigated are: travel activities, modes of travel, distance, time and speed of travel, trip destinations, reasons for travel, frequency of travel, complexity of travel, and, spatial familiarity. Case study results reveal several commonalities and differences between the three field sites: (a) the car is the dominant mode in Ottawa, compared to a wider diversity of modes operating in the Southeast Asian field sites; (b) individual respondents in Yogyakarta travelled by a greater number of modes than those in Ottawa and Kuala Lumpur; (c) car modal share increased on non-work days compared to work days in all sites; (d) respondents in Ottawa exhibited the highest mean travel distances, travel times and speeds, followed by respondents in Kuala Lumpur and Yogyakarta; (e) the urban fringe was the destination of over half of all stops in both the Kuala Lumpur and Yogyakarta surveys, compared to less than half in Ottawa; and, (f) across field sites and survey days, the clusters with the highest mean tours per day have daily destinations concentrated in the urban fringe.
